The invention adopts three-dimensional human body scanning data to analyze the young girls and divides the human body into a lower body and an upper body for explanation. It mainly solves three problems: the problem of the two-dimensional form relationship between the local three-dimensional body characteristics of the human body and the template curve, the problem of realizing the diversity of the body shapes and the problem of realizing the individual clothing templates.

The clothing pattern generating method based on three-dimensional scanning comprises the following steps:

s1: scanning by a human body three-dimensional scanner to obtain three-dimensional human body scanning data, defining human body characteristic parts and a measuring method thereof to describe human body shape characteristics aiming at the three-dimensional human body scanning data, and simultaneously decomposing the specificity of the individualized garment template into the specificity of template structure lines to obtain a template curve form;

Further, according to the three-dimensional human body scanning data, after the human body is divided into a lower body and an upper body, body type characteristics of the lower body and the upper body are respectively described;

determining the characteristic part of the lower body, measuring the characteristic part, classifying the body type of the lower body, analyzing data and subdividing local characteristics to determine the relationship between the characteristic part of the lower body and the corresponding template curve;

The above "upper body and lower body" are defined by the waist circumference in anthropometric terms, which is referred to as the upper body above the waist circumference and the lower body below. Therefore, the clothing pattern generation method based on three-dimensional scanning is an analysis method mainly developed aiming at the geometric form of the human body characteristic part, and the relation between the form characteristic of the part and the clothing pattern curve is researched from the view point of parameters required by clothing modeling.

Based on the above, the present invention provides the following specific embodiments:

the invention takes the young girl university student group which completes physiological development as a scanning object. The determination of the sample size n is one of the important contents of the sampling scheme, the selected sample represents more people as much as possible, and the error of the important size index is within an allowable range.

Extracting a sample from a single population to measure an item, x_i(i is 1 to n) and the sizes of the respective parts of the human body follow a normal distribution as known from anthropometry

For the sample mean, a 95% confidence level is typically used in industrial production and scientific research, and the error is:

then the sample size

Wherein

Where A is the relative assurance error. Generally, the value of A in major scientific research is 1-2%, the value of general scientific research is 3-4%, and 5% is suitable for industrial production. In order to reduce the error, the value of A is 1%. cv is a coefficient of variation, and the larger the coefficient of variation indicates the larger the individual fluctuation range, the larger the required sample size. s is the standard deviation of the samples and,

In order to obtain the characteristic size variation coefficient of young women, the sizes of the heights, the chest circumferences, the waistlines, the abdominal circumferences, the hip circumferences and the like of a plurality of young women can be measured. The cv value of the main measurement items of the body for clothing was calculated from these data, and the sample amount n required for the fractional measurement was obtained, and the calculation results are shown in table 1.

TABLE 1 determination of sample size of measurement object

First, lower body characteristics and individualized pants prototype template generation rules

(I) study of lower body figure characteristics

In order to quantify the local characteristic form of the human body, the invention adopts a measuring method, and the method considers the relationship between the human body structure and the clothing structure in the human body measuring process: the side line of the body is used as a boundary to divide the human body into a front part and a rear part, and the measured values of the side line of the human body correspond to the front piece structure line and the rear piece structure line of the garment respectively.

The invention firstly defines human body characteristic points and basic characteristic lines, which comprise: abdomen salient points, hip salient points, crotch bottom points, lower body lateral midline and the like. Wherein, abdominal convex point: in a side view of a human body, a convex point at the outermost part of the abdomen; buttock salient point: in a side view of a human body, the outermost convex point of the hip part; crotch bottom point: making a median plane of waist projection in the side view, and making an intersection point of the median plane and a median sagittal plane of the human body; lower body lateral midline: divided into a lateral midline and a medial midline. In a side view, the former is a connecting line between the middle point of waist thickness and the middle point (outside) of calf girth thickness; the medial midline is the connecting line of the crotch base point and the thickness (medial side) of the calf girth.

The measurement of the sizes of all the characteristic parts is realized by using a human body three-dimensional scanner and the operation of experiment software (such as Imageware). The lower body characteristic part and the measuring method thereof are as follows: for example, the waist feature is specified, and the waist circumference (horizontal girth of the thinnest part of the waist), the waist width (projected distance of the waist circumference in front view of the human body), the front waist circumference (front half length of the waist circumference bounded by the lateral centerline), the back waist circumference (rear half length of the waist circumference bounded by the lateral centerline), the front waist thickness (projected length of the front waist in side view of the human body), the back waist thickness (projected length of the back waist in side view of the human body), and the waist height (vertical distance from the plane of the waist to the ground) can be measured. And respectively measure abdominal, crotch, hip, thigh, knee, calf, ankle, body side, etc. in a similar manner.

In order to characterize the torso regions of the female lower body (e.g., bellied, flat, hip-up, hip-down, abdomen-lift, abdominal obesity, abdomen-lift, hip-flat, abdominal hip-lift, etc.), the present invention introduces parameters to quantify the characterization of these regions: the ratio (R) of the front waist thickness to the waist thickness_{Thickness of waist}) Representing the waist characteristics, the ratio (R) of the front abdominal thickness to the abdominal thickness_{Thickness of abdomen}) Representing the abdominal characteristics, the ratio of the posterior hip thickness to the hip thickness (R)_{Thickness of buttocks}) And (difference between waist height and hip height)/(difference between waist height and crotch height) (R)_{High of buttocks}) To illustrate the hip characteristics. And taking the indexes as the characterization parameters of the corresponding characteristic parts. The invention divides the lower body shapes with different differences into different categories according to the characteristic indexes, so that when the individual trousers are generated, the categories of the individual trousers can be found according to the characteristic indexes of a certain characteristic part of a specific human body, and further the curve generation rules of the individual trousers can be found.

To R_{Thickness of waist}、R_{Thickness of abdomen}、R_{Thickness of buttocks}、R_{High of buttocks}And (4) carrying out box diagram analysis by using SPSS software, finding out singular values in the box diagram, and removing the singular values. The four ratios were ranked by 0.1 step, and the number of people falling in each step was counted, and the results are shown in Table 2.

TABLE 2 lower body characteristic location parameter distribution (Unit: human)

According to the practical situation, the waist feature is divided into one gear, and the gear dividing coefficient is 0.5; the abdominal characteristics are divided into three grades, and the grading coefficients are 0.4, 0.5 and 0.6; the hip thickness characteristic is divided into two grades, the grading coefficient is 0.5 and 0.6, the hip height characteristic is divided into three grades, and the grading coefficient is 0.5, 0.6 and 0.7. By combining these indices, the shape of the lower torso is classified into 1 × 3 × 2 × 3 or 18.

(II) research on prototype template curve generation rule of trousers

The invention regards the lower body as close-fitting individualized trousers, regards the characteristic points and lines of the human body as the structural points and lines of the close-fitting individualized trousers, restrains the relationship between the structural lines from the directions of height regulation and girth regulation respectively, and researches the parameter relationship between the characteristic parts and the structural lines of the clothes.

Wherein, regarding the determination of the height rule:

the height of the lower body characteristic part determines the longitudinal distribution of important structure lines such as waistline, abdominal circumference, hip circumference and the like in the trousers in the sample plate. In order to explore the rule of the positions of the girth of each characteristic part in the lower body, the invention introduces the concept of 'height coefficient of the characteristic part', namely the ratio of the height of the characteristic part to the height of the lower body.

After measuring the heights of the waist, abdomen, hip, thigh and knee in the test subject, calculating the ratio of the heights to the height, sorting the heights by taking 0.1 as the grade difference, and counting the number of people falling in each grade, wherein the results are shown in table 3.

TABLE 3 lower body height characteristic parameter distribution (Unit: human)

As can be seen from the table, 98% of the population in the waist height coefficient is concentrated in 0.55-0.64 grades; the number of people with 83% of the abdomen height coefficient is concentrated in the 0.45-0.54 grade, and the number of people with 17% of the abdomen height coefficient is concentrated in the 0.55-0.64 grade; 47% of people in the hip height coefficient are concentrated in 0.35-0.44 grades, and 51% of people are concentrated in 0.45-0.54 grades; 67% of people in the height coefficient of the thigh root are concentrated in 0.35-0.44 grades, and 26% of people are concentrated in 0.25-0.34 grades; 37% of the population in the knee height coefficient is concentrated in 0.15-0.24 grades, and 63% of the population is concentrated in 0.25-0.34 grades. Based on table 3, the height of the girth of the human body feature part is linearly and obviously correlated with the height by analyzing the trend of the scatter diagram of the height and the height of the human body feature part and then analyzing the correlation between the height of each feature part and the height.

Again, regarding the determination of the girth rule:

the difference of the shape of the cross section of the circumference of the human body is mainly expressed as the difference of the flatness degree. The invention classifies the section shape characteristics of the girth of each characteristic part and classifies the section shape characteristics by adopting the thickness/width value.

In the experimental content, the invention performs fitting on the waist circumference, the abdominal circumference, the hip circumference, the thigh circumference, the knee circumference and the calf circumference; in the experimental method, firstly, a box-type graph is used for analysis, singular values of the ratio are removed, the maximum value and the minimum value are found, classification is carried out between the two values according to the grade difference of 0.05, the grades with the number of less than 5 persons are deleted without analysis, the classification result is shown in a table 4, and the table shows that all grades have obvious aggregation phenomena, which indicates that the thickness-width ratio of most women is regularly distributed.

TABLE 4 cases of grading the circumference parts according to the thickness-width ratio

Based on table 4, by analyzing the correlation between the width and thickness values of the characteristic parts of the human body and the circumference values, it is possible to obtain a large correlation coefficient between the circumference (i.e., the front waist circumference, the rear waist circumference, the front abdominal circumference, the rear abdominal circumference, the front hip circumference, the rear hip circumference, the thigh circumference, the knee circumference, and the calf circumference) of each characteristic part of the human body and the width and thickness of the cross section thereof.

Finally, regarding the determination of the crotch camber line rule:

the contour curve of the waist-crotch of the human body is obtained by utilizing the sagittal plane and the 3D B spline simulation in the human body. In the experiment, the body surface length from the convex point of the abdomen to the crotch base point in the sagittal plane of the human body is defined as the curve length of the front crotch curve; the body surface length from the hip prominence point to the crotch base point is defined as the back crotch camber line length.

On the side view of the contour line, as shown in fig. 1, the waist-abdominal distance, waist-hip distance, and crotch distance are measured; meanwhile, the length of the front midline, the length of the rear midline, the length of the front crotch curve and the length of the rear crotch curve are measured.

A plane vertical to the Z axis is made through the bottom point of the crotch, and then the lateral line of the upper body can be obtained; making a line segment parallel to the Z direction from the crotch bottom point, making a line segment parallel to the-Y direction from the abdomen salient point, and intersecting the two line segments to determine the height and the width of the front crotch; similarly, the height and width of the rear gear can also be determined; dividing the front and back crotch height into five equal parts to obtain equal lines, and respectively intersecting the lines with the contour lines of the front and back crotch at A₁～A₅And B₁～B₅Dots, as shown in fig. 1. In the experiment, the shape of the crotch curve line of the experimental object has certain similarity, and the crotch curve has better correlation with other indexes (such as waist-abdomen distance and the like) which are easy to measure.

Second, upper body characteristic and individual upper-loading prototype template generation rule

(I) determination and measurement of chest characteristic points, lines

Chest height point: the most prominent point of the chest BP, i.e. the breast point; milk root point: the lowest point of the junction of the breast and the upper body; chest circumference: the horizontal circumference of the transthoracic elevation point is represented by B; surrounding the root of the breast: horizontal circumference of the breast-crossing root point, denoted RB; a body side line: the boundary line of the front part and the rear part of the upper body is represented by LL, and the middle perpendicular line of the thickness of the milk root circumference is taken as the lateral line of the upper body in the experiment; front half bust: the body lateral line is taken as a boundary, and the front half part of the bust is expressed by FHB; anterior galactoside rhizosphere: the body lateral line is used as a boundary, and the first half part of the radicle periphery is expressed by FHRB.

Because there are more characteristic points of the upper body part and the determination process is more complicated than that of the lower body part, the description steps are as follows:

1. the chest height point and the bust section are determined. And determining the chest height point BP by a software conversion view and a space coordinate positioning function. Intercepting point clouds through the BP point, and automatically obtaining a chest circumference point cloud section; 2. and determining the mammary root point and the mammary root surrounding section. Wherein, the cross section of the point cloud of the chest circumference and the cross section of the breast root point and the breast root circumference are shown in fig. 2.

(II) chest saver model

1. Chest model

The female breast, especially when wearing a corset, is considered herein as approximately a cone, the radius of the breast base R and the chest height H determining the shape of the cone, as shown in fig. 3 (a). As can be seen from the solid geometry principle, the cone can be flattened into a fan shape, as shown in fig. 3 (b).

Observing the relationship between the human body structure and the pattern, it can be found that the breast is located at the front part of the human body, the breast dart is located at the front part of the pattern, and the correlation between the breast dart and the front half bust and the front half galactoside circumference should be the highest from the principle of garment modeling. The invention generates the chest dart by adopting the relation between the front half chest circumference and the front half galactose root circumference.

To express the relationship between breast and thoracic provinces, the experiment introduced some parameters to create a mathematical model. Wherein DG is used to represent the difference between chest circumference and breast root circumference, DHG is used to represent the difference between anterior half chest circumference and anterior half breast circumference, and alpha is used_tIndicating the angle of the thoracic province and L the length of the thoracic province. This experiment abstracts the body chest convexity into a cone model, then has following mathematical relationship:

2. chest model

As can be seen from the principle of garment modeling,

namely the thoracic province model. By experimental analysis, in this model, α_tThe relevance to H, R, DG, DHG and H/R is obvious, especially to DHG.

3. Chest province classification model

Due to alpha_tThe relevance with DHG is most obvious, and the invention is used as the basis to carry out thoracic province classification, namely, the DHG is classified to establish a thoracic province classification model:

the DHG value is first calculated and ranked. The distribution range of the value is found to be 0-9 by calculation. The difference between the two shifts was set to 1, the DHG was divided into nine shifts, and the number of persons who met the conditions of each shift was counted, and the results are shown in table 5.

TABLE 5 DHG grading and people statistics

Then, the relevance of DHGs of each stage is analyzed. The analysis results show that the correlation is significant.

And finally, taking the DHG of each grade as an independent variable and the corresponding chest dart angle as a dependent variable, and performing regression analysis and error test to perform regression analysis and error test. Let the classification model of the chest province built by DHG in different grades be alpha_PdhgThe results of the regression analysis are shown in Table 6. Error checking using | α_Pdhg-α_tThe ratio of the number of people with less than or equal to 3 degrees to the total number of people is between 84 and 87.9 percent.

TABLE 6 thoracic province classification model built by DHG grading

According to the above idea, a model of a characteristic portion of a waist, a shoulder, a neck, a shoulder, an armpit, or the like, and a characteristic portion classification model can be obtained in this order.

The invention divides the upper body into five parts of chest, waist, shoulder, neck, shoulder and axilla, establishes a part characteristic model for the parts, adopts a stepping mode to refine the part model into a part classification model, and establishes the corresponding relation between the characteristic part and an individualized sample plate curve.

Third, realizing the ready-made clothes sample plate based on the individual prototype sample plate

Study on clothing bulk distribution rule

In the overall design of the experiment, the experiment is divided into three stages of obtaining the state of the bulk space, quantitatively describing the bulk and exploring the bulk rule; in the technical means, firstly, scanning a human body before and after dressing to obtain point cloud data; then, superposing the data of the clean body and the dressing human body to obtain a 'clothing-human body' section ring of each characteristic part; secondly, selecting sampling points, and measuring the distance between the clothes and the human body in the cross-section ring, namely the distance looseness; thirdly, a rule between the distance bulk and the given bulk is explored through data analysis, and a model of 'given bulk-distance bulk' is established; and finally, establishing a distance loose-template increment model by researching the quantitative relation between the distance loose and the clothing template increment, converting the given loose into the circumference increment of the clothing template by taking the distance loose as an intermediate bridge, and completing the conversion from the individual prototype template to the individual clothing template.

1. Clothing bulk test

In the experiment, a college and girl university student is selected as a human body model, the body type characteristics of the college and girl university student refer to GB/T1335-2008, and the sizes of the characteristic parts are as follows: 164cm in height, 84cm in chest circumference, 66cm in waist circumference, and 90cm in hip circumference.

The experiment takes the suit-dress as a sample garment for research. In total, 7 tops, 4 trousers, the sample garment bulk and the control part size are shown in tables 7 to 8. These garments encompass all of the range of bulk that may be involved in a practical garment.

TABLE 7 sample clothes lower garment size table

TABLE 8 sample clothes size table

After human body data before and after dressing are obtained through scanning of a human body three-dimensional scanner, the net body scanning data and the dressing scanning data are read in sequence, and then the superposition data of the net body scanning data and the dressing scanning data can be obtained. The position of the characteristic part of the human body is determined by adopting a three-dimensional coordinate adjusting tool of software, and then a clothing-human body section ring of each characteristic section part of the human body can be obtained by utilizing a parallel section tool and a multi-angle view tool, as shown in figure 4. Based on this, the measurement work of the distance looseness can be carried out.

In the experiment, the sections of hip circumference, thigh circumference and knee circumference are cut at the lower part, and the sections of shoulder (shoulder end point), chest circumference, waist circumference, abdomen circumference and hip circumference are cut at the upper part. Since the measurements of the top and bottom garments are identical in terms of the method, the process and method of measuring the distance bulk will be described only with reference to the measurement of the hip circumference of the bottom garment.

First, the body side line and the center line of the human body are specified, and the intersection thereof is set as the origin of coordinates O (0, 0). The method has similar processes in the foregoing and is not repeated here.

Then, the position of the intermediate point is determined. As shown in FIG. 5 (only the left half is taken as an example), the width of the left and right human bodies is trisected to obtain a bisecting point O₁、O₂(ii) a Dividing one part close to the body side into two parts, and determining an equal division point O₃. Per O₁、O₂、O₃Making a perpendicular line of the medial line of the human body; the intersection points of the vertical lines and the human body front contour line are named as A from the front middle to the body side direction₀～A₄The intersection points with the contour line of the human body rear part are named as B from the rear middle to the body side direction in sequence₀～B₃(ii) a The intersection points with the front contour lines of the trousers are named as A from the front middle to the side direction_1n～A_4n(n is 1,2,3, 4; the first foot code represents the position of the intersection, the second foot code represents the serial number of the pants, the same below), the intersection point with the rear contour line of each pants is named as B from the rear middle to the body side direction_1n～B_3n(n is 1,2,3, 4). Due to the limitation of spatial position in the figureIn FIG. 5, only at A₁The position labels show all intersection codes.

Finally, the distance bulk is measured. The experiment adopts a method of carrying out coordinate translation according to the relation between the clothes and the human body by taking a human body contour line measuring frame as a support, respectively measuring the sizes of the corresponding parts of the human body and the clothes, and obtaining the distance looseness by calculating the difference value of the human body contour line measuring frame and the clothes. In the experimental process, distance looseness measurement work is respectively carried out on the left part and the right part of the trousers, and the average value of the distance looseness measurement work is obtained to be used as the final experimental result.

2. Model of' given bulk-distance bulk

After obtaining the original data of the distance bulk at different positions in different bulk states, the relationship between the distance bulk and the given bulk value will be discussed here. For this reason, correlation analysis was first performed, and the results showed that there was a significant correlation between the two. A linear regression analysis was performed using the given bulk x as the independent variable and the distance bulk y as the dependent variable, and the results are shown in Table 9.

TABLE 9 model of "given bulk-distance bulk" of hip circumference of pants

In the same way, the distance looseness of the thigh circumference and the knee circumference of the pants can be analyzed.

3. Distance loose-sample increment model

If the looseness relation between the clothes and the human body in the clothes-human body section ring is abstracted into two concentric circles as shown in fig. 6, a model can be established: delta_L＝L_c-L_b＝DE*α

Wherein DE is the distance bulk R_c-R_b；Δ_LIndicates the length (L) of the surface of the garment in a certain area_c) Length (L) of human body surface_b) A difference of (d); alpha is the angle between the two measuring points, and the measuring method is shown in figure 7 (in the figure, the cross section of the No. 3 trousers-the hip circumference of the human body). The positions of the sampling points (i.e., the intermediate points) are the same as those of the sampling points in fig. 5. It should be noted that the loose distance in the model is substantially the radial distance between the garment and the surface of the human body; due to the narrow space between the garment and the human body, the radial distance value and the distance looseness are approximately equally processed.

The model can calculate the template increment corresponding to each part. Next, the procedure of "loose distance-sample increment" will be described by selecting the 3# pants as a reference.

As shown in table 10, the given bulk of the 3# pants is x ═ 10cm, and the value is substituted into the regression formula in the table, so that the distance bulk y can be obtained; then the distance loose amount and the measured angle are substituted into a distance loose amount-sample plate increment model, and the numerical value delta of the sample plate increment of each sampling position can be obtained_L。

4. Method for converting individual prototype sample plate into ready-made clothes sample plate

The invention takes the process of converting the trousers prototype template into the individual trousers template as an example to explain the process.

Firstly, drawing an individualized trousers prototype template, wherein drawing data is as follows: the prototype sample has a length of 98cm, a waist length of 68cm, a hip circumference of 90cm and a foot opening of 20cm, and has a looseness (set value) of 2cm at the waist position, no looseness at the hip position, and looseness of 4cm at the knee circumference and the foot opening, as shown in fig. 8 (a). The template can be understood as an expanded view of the topography of the tights.

Then, the amount of looseness of the pants at the hip circumference was set to 10cm, and the 3# pants in the test sample clothes were used as a reference. According to the corresponding relation between the human body and the clothing structure, the position of the sampling point is found on the hip circumference line of the prototype template by referring to the determination method of the sampling point in FIG. 5; the distance bulk values at the hip circumference can be obtained by the regression formula in table 9, and then these values are substituted into the regression formula in table 10, so that the template increment Δ at the sampling point can be obtained_L. Finally, the incremental value delta calculated by the experiment is calculated_LAnd the size of the hip circumference of the trousers corresponding to the characteristics of the lower body of the model can be obtained by adding the sampling points to the corresponding positions. It should be noted that, in the incremental adding process, consideration is given to the template balance as a basis, and the direction of incremental addition is flexibly considered.

By adopting the same method, the increment of the sample garment caused by the addition of loose quantity at the thigh circumference and the knee circumference can be calculated, and the specific process is omitted. Finally, the curve state is adjusted, and the trouser ready-made clothes sample plate with the bulk and according with the lower body shape of the experimental model can be obtained. In conclusion, through the model of 'given bulk-distance bulk-sample increment', the conversion from the individualized prototype sample plate to the individualized garment sample plate can be realized, so that the aim of the experiment is fulfilled.

In addition, the upper end of the first supporting member 201 is fixed with a peripheral member 203 for covering the upper end opening of the first supporting member 201 and for defining the space range in which the human body stands.

Further, the power output end of the first power assembly 102 faces upward and is fixed with the lower end of the transmission member 101a, so as to drive the transmission member to rotate. The transmission component 101a is further connected with the speed reducing component 105 through the transmission component 104 to form transmission, wherein the transmission component 101a transmits the torque to the transmission component 104, the transmission component 104 transmits the torque to the speed reducing component 105 again, the speed reducing component 105 can adopt a worm gear speed reducer which is provided with an input shaft 105a and an output shaft 105b which are perpendicular to each other, the input shaft 105a is a high-speed end, and the output shaft 105b is a low-speed end after the speed reduction of the worm gear.

Specifically, the transmission assembly 104 includes a first mating member 104a, a second mating member 104b and a transmission main shaft 104c, wherein the first mating member 104a and the second mating member 104b are bevel gears vertically mating with each other, and the connection therebetween can form a transmission in a vertical direction.

Referring to fig. 12 to 15, a second embodiment of the present invention is different from the previous embodiment in that: the lower end face of the rotating assembly 106 is further provided with a platform compensation unit 400, the platform compensation unit 400 is used for: when the rotating assembly 106 rotates, the platform compensation unit 400 can adjust the balance state of the rotating assembly 106 in real time without stopping the operation of the rotating assembly, so as to compensate the standing inclination deviation of the human body in real time, and acquire each accurate item of data of the human body information.

Platform compensation unit 400 includes a linkage assembly 401, a second power assembly 402, and a second carriage assembly 403. Wherein, the second bracket assembly 403 is used for fixing and mounting the second power assembly 402; the second power assembly 402 is used to provide power to compensate for motion; the connecting assembly 401 is used for connecting the second power assembly 402 with the rotating assembly 106 and transmitting the output power of the second power assembly 402 to the rotating assembly 106, so as to perform compensatory adjustment on the inclination state of the rotating assembly 106. The lower end of the second power assembly 402 is fixed to the lower end surface of the outer member 203 through the second bracket assembly 403, and the upper end of the second power assembly 402 is connected to the lower end surface of the rotating assembly 106 through the connecting assembly 401. The second power assembly 402 of the present invention is vertically disposed, and can be implemented by a member capable of performing linear telescopic motion, such as a servo electric cylinder, and the telescopic end of the second power assembly 402 faces upward.

Further, the connecting assembly 401 includes a first fitting member 401a and a second fitting member 401b, wherein the upper end of the first fitting member 401a is embedded in the second fitting member 401b, the lower end thereof encloses the upper end of the second power assembly 402, and the first fitting member 401a is movable in all directions at the end of the second power assembly 402. Wherein the second fitting member 401b is connected to the rotating assembly 106.

Further, the first fitting member 401a includes a first connecting portion 401a-1 and a clamping portion 401a-2, and a ball 402a is fixed to the upper end of the second power assembly 402. The interior of the clamping part 401a-2 is provided with a hollow space M matched with the sphere 402a, and the hollow space M is used for wrapping the sphere 402a in a clearance fit manner, so that the sphere 402a can freely move in the hollow space M. The first connecting part 401a-1 is located at the upper end of the clamping part 401a-2, and is a ring structure with an outer diameter of the edge larger than that of the clamping part 401a-2, and is used for connecting the first fitting part 401a and the second fitting part 401 b.

The second fitting member 401b includes a sliding portion 401b-1 on the upper end surface and a second connecting portion 401b-2 on the lower end surface, and the second connecting portion 401b-2 is engaged with the structure of the first connecting portion 401a-1 and covers the outer edge of the first connecting portion 401a-1 in a clearance fit manner, so that the first fitting member 401a and the second fitting member 401b can rotate horizontally relative to each other.

Further, the platform compensating units 400 are provided in at least three groups and are uniformly distributed on a circumference of the lower layer of the rotating assembly 106. When it is desired to adjust the rotating assembly 106, one (or two, three) of the second power assemblies 402 is activated to extend or retract. When the horizontal rotation of the rotating component 106 is not considered, since the second engaging element 401b is fixed to the lower side of the rotating component 106 through the sliding part 401b-1, it can be kept stationary relative to the rotating component 106, and the first engaging element 401a cannot be spatially displaced relative to the second engaging element 401b (in addition, the first engaging element 401a is connected to the rotating component 106 in a manner similar to a "ball joint"), so that the second power component 402 can raise or lower the height of the rotating component 106 at this point through the control of the length thereof, and finally control the gradient of the rotating component 106. It should be noted here that: the horizontal grade of the spinner assembly 106 may be finely adjusted when one or two of the second power assemblies 402 are activated, and the vertical height of the spinner assembly 106 (relative to the coarse adjustment of the motion unit 100) may be finely adjusted when three second power assemblies 402 are simultaneously activated.

When considering the horizontal rotation of the rotating assembly 106, since the upper end of the second fitting part 401b has the sliding part 401b-1 fitted to the annular sliding groove 106a, when the second power assembly 402 is activated, the connecting assembly 401 can support the rotating assembly 106 and the rotating assembly 106 can horizontally rotate relative to the connecting assembly 401. From the above, the present invention can still adjust the horizontal slope of the rotating assembly 106 and the vertical height thereof without affecting the horizontal rotation of the rotating assembly 106.

Referring to fig. 16 to 22, a third embodiment of the present invention is different from the previous embodiment in that: the human body three-dimensional scanner is of a detachable and assembled structure. Wherein:

the action unit 100 is integrated and is connected with the base assembly 200 through the lower end of the connecting plate 101e (the lower end of the connecting plate 101e is connected with one end of the first support 201 through a bolt);

the other end of the first support member 201 is connected with the second support member 202 through a bolt;

the top of the first support 201 is bolted to the horizontal panel of the periphery 203.

External wires S of all electric equipment (including the first power assembly 102 and the like) are uniformly laid in the first supporting piece 201, and the first supporting piece 201 is of a hollow box structure.

Because the human body three-dimensional scanner is large-scale equipment and is not easy to move and carry, the human body three-dimensional scanner is designed into a detachable and assembled structure, and the human body three-dimensional scanner is designed as follows: the external wires S of all the electric equipment are divided into two sections, and the two sections can be detached and assembled simultaneously along with all the functional units.

The two-segment type electric wire S is connected by a wire connection mechanism J, which includes a cover assembly 500 and a docking assembly 600. The covering assembly 500 has two halves with the same structure and is used for wrapping and clamping and connecting the ends of two butt-jointed wires S; and the docking assembly 600 serves to connect, lock, and compress and densify the wires S inserted into the interior of the closure assembly 500. The covering assembly 500 of the present invention can be divided into a first unit 501 and a second unit 502, which have the same structure, are opposite to each other and are spliced, and are fixed by the docking assembly 600, and the structure of the first unit 501 is first described in detail herein.

The first single body 501 includes a first receiving part 501a and a first pressing part 501 b. The first container 501a mainly includes: the tubular body is axially cut into one half of the structure and comprises an external shell and an accommodating space in the shell; and the first pressing piece 501b is a block-shaped structure for directly telescopically pressing the electric wire S-terminal. The first accommodating member 501a is provided with an insertion hole 501a-1 matched with the first pressing member 501b, the first pressing member 501b is inserted into the insertion hole 501a-1 and extends into the first accommodating member 501a, and the first pressing member 501b can stretch and slide back and forth in the insertion hole 501a-1 to squeeze and loosen the wire S.

A pair of limiting blocks 501c are disposed inside the first accommodating member 501a (the limiting blocks 501c are fixed on the inner sidewall of the first accommodating member 501 a), and in a spatial position, the limiting blocks 501c are located at two ends (symmetrically distributed) of the first pressing member 501 b. It should be noted that: the side surface of the limiting block 501c opposite to the first pressing piece 501b is provided with a first protrusion 501c-1, two end surfaces of the first pressing piece 501b are provided with first sliding grooves 501b-1 matched with the first protrusion 501c-1, the first protrusion 501c-1 is embedded in the first sliding groove 501b-1, and the direction of the first sliding groove 501b-1 is consistent with the direction of the insertion hole 501a-1, so that the first pressing piece 501b can linearly and telescopically slide along the direction of the first sliding groove 501 b-1.

In the present invention, both ends of the first single body 501 can be inserted with the electric wire S and enter the inside of the first accommodating member 501a, and the end of the first accommodating member 501a has a first through hole 501a-2 fitted to the electric wire S, and it is obvious that the first through hole 501a-2 is a semicircular hole fitted to the outer diameter of the cross section of the electric wire S because the first single body 501 is a half structure of the covering assembly 500. The ends of the electric wires S penetrated from both ends of the first container 501a are overlapped, and the first pressing piece 501b can press the overlapped electric wires S by the pressing of the docking assembly 600. Preferably, the inner edge of the first pressing piece 501b is provided with a densely distributed scissors-like bifurcated structure: each scissor-like bifurcation is in the form of a sheet and the array is in plurality. The middle corner of the branched structure can press the electric wire S. Preferably, the first pressing member 501b may be made of rubber or other flexible and tough insulating materials, which can ensure the compactness of extruding the connector of the electric wire S, prevent the electric wire S and the first pressing member 501b from being damaged, and is non-conductive, safe and reliable.

Further, the first single body 501 further includes a sealing member 501d for ensuring a waterproof and dust-proof sealing function between the surface layer of the electric wire S penetrating into the first accommodating member 501a and the outer port of the first accommodating member 501 a. The sealing member 501d includes a push block 501d-1 which is in press contact with both ends of the first pressing member 501b, a sealing portion 501d-3 which is provided inside the first penetration opening 501a-2, and a transmission portion 501d-2 which connects the push block 501d-1 and the sealing portion 501 d-3. The pushing block 501d-1 is a block that can slide linearly along the longitudinal direction of the first accommodating element 501a, and the two ends of the first pressing element 501b are provided with a docking port 501b-2 corresponding to the pushing block 501d-1, where the docking port 501b-2 is a notch structure at the outer end of the first pressing element 501b, the bottom surface of the docking port 501b-2 is a slope, and the slope makes the width of the outer port of the docking port 501b-2 larger than the width of the inner port. Therefore, when the outer end of the pushing block 501d-1 is inserted into the docking port 501b-2, if the initial state is set as: the outer end of the pushing block 501d-1 abuts against the inner opening of the abutting opening 501b-2, so that when the first pressing piece 501b is pressed upwards, the top surface of the abutting opening 501b-2 can press the end of the pushing block 501d-1, so that the pushing block 501d-1 slides outwards in a straight line.

The above-mentioned "pushing block 501d-1 slides linearly outward" is realized by further including the following structure: the limiting block 501c is provided with a second sliding groove 501c-2 matched with the pushing block 501d-1, and the pushing block 501d-1 is inserted into the second sliding groove 501c-2 and can slide linearly under the pressing of the slope surface of the interface 501 b-2.

In the invention, the two ends of the inside of the first accommodating piece 501a are respectively provided with an accommodating groove 501a-3, the accommodating grooves 501a-3 are accommodating spaces positioned at the inner side of the first penetrating opening 501a-2, and the inner end of the accommodating grooves can be provided with a plug. The receiving groove 501a-3 is opposite to and communicated with the first through opening 501a-2, and the sealing portion 501d-3 is embedded in the receiving groove 501 a-3. The sealing portion 501d-3 in the present invention may be a half structure of a bellows, which is capable of length expansion and contraction. A transmission part 501d-2 for transmitting linear motion is arranged between the sealing part 501d-3 and the pushing block 501d-1 (the transmission part 501d-2 is a middle transitional block-shaped body structure), so when the pushing block 501d-1 slides outwards linearly by the first pressing piece 501b, the pushing block 501d-1 presses the sealing part 501d-3 through the transmission part 501d-2, so that the sealing part 501d-3 is compressed and the cross section is expanded, the contact pressure between the sealing part 501d-3 and the accommodating groove 501a-3 and the contact pressure of the wire S penetrating through the sealing part 501d-3 are increased, and the compactness is also improved.

It should be noted that: the wire S can sequentially pass through the first through hole 501a-2 and the sealing portion 501d-3 and be inserted into the first accommodating member 501a, and the sealing portion 501d-3 covers the periphery of the wire S.

As can be seen from the above, in the present invention, the second unit 502 and the first unit 501 have the same structure and are aligned with each other (the openings of the two housings are aligned with each other and cover each other to form a closed structure). Specifically, the second single body 502 includes a second accommodating member 502a corresponding to the first accommodating member 501a, a second penetrating opening 502a-1 corresponding to the first penetrating opening 501a-2 is formed at an end of the second accommodating member 502a, and when the first single body 501 and the second single body 502 are just spliced, the first penetrating opening 501a-2 and the second penetrating opening 502a-1 can jointly form a threading opening K-1 matched with the electric wire S. In addition, the second unit 502 further includes a second pressing piece 502b corresponding to the first pressing piece 501b, the second pressing piece 502b can be inserted into the second accommodating piece 502a, and the rest corresponding parts are not described in a list.

In the first single body 501 (and the second single body 502) according to the present invention, a functional region formed by the first pressing piece 501b, the stopper 501c and the sealing piece 501d inside the first accommodating piece 501a is a "connecting unit" capable of connecting a set of electric wire S connectors. Preferably, in the present invention, a plurality of "connecting units" may be arranged in parallel in the first accommodating part 501a to be suitable for a plurality of thread ends. The invention is illustrated in the figures as two sets of "connecting units", without limiting the scope of protection of the invention.

In the present invention, the docking assembly 600 is sleeved on the periphery of the covering assembly 500, and locks the combination between the first single body 501 and the second single body 502, and the inner sidewall of the docking assembly 600 can inwardly press the first pressing piece 501 b.

Specifically, the docking assembly 600 includes a first end cap 601 and a second end cap 602 that are coupled to the two end structures of the closing assembly 500, and a tightening member 603 that connects the first end cap 601 and the second end cap 602, that is: when the first monomer 501 and the second monomer 502 are just spliced, the first end cover 601 and the second end cover 602 can be respectively sleeved at two ends of the covering assembly 500, the outer end faces of the first end cover 601 and the second end cover 602 are respectively provided with a second threading opening K-2 corresponding to the threading opening K-1, and the electric wire S can sequentially pass through the second threading opening K-2 and the threading opening K-1 to enter the covering assembly 500 and is finally extruded and compacted.

Both the first end cap 601 and the second end cap 602 are structured as follows: one end is an open end which is not structurally closed; the other end is a plugging end, and a second threading opening K-2 penetrates through the plugging end. But the difference between the two is that: the outer side wall of the open end of the first end cap 601 has external threads 601a, and the open end of the second end cap 602 has a ring of first limiting rings 602 a. The first confinement ring 602a has an inner ring diameter that is the same as the open end of the second end cap 602 and an outer ring diameter that is larger than the open end of the second end cap 602.

Specifically, one end of the tension member 603 has a second limiting ring 603a fitted to the first limiting ring 602a, the inner diameter of the second limiting ring 603a is smaller than the inner diameter of the tension member 603 and the outer diameter of the first limiting ring 602a, and the inner diameter of the tension member 603 is slightly larger than or equal to the outer diameter of the first limiting ring 602 a. In summary, after the tension member 603 is sleeved on the second end cap 602, the second limiting ring 603a can pull the first limiting ring 602a (i.e. the tension member 603 can be connected to the second end cap 602 through the limitation between the second limiting ring 603a and the first limiting ring 602 a).

The tension member 603 has an inner wall at the other end thereof provided with an internal thread 603b to be engaged with the external thread 601a, and is connected to the first end cap 601 by engagement of the two. Therefore, when one end of the tension member 603 is connected to the second end cap 602, the other end is rotated by the screw thread engagement, so as to tension the first end cap 601 and the second end cap 602 at the same time, thereby shortening the distance between them.
