Referring to fig. 4 to 7, a second embodiment of the present invention is different from the previous embodiment in that: the lower terminal surface of rotating assembly 201 still is provided with platform compensation unit 400, and platform compensation unit 400 is used for: when the rotating assembly 201 rotates, the platform compensation unit 400 can adjust the balance state of the rotating assembly 201 in real time without stopping the operation of the rotating assembly, so as to compensate the inclination deviation of the standing human body in real time, and acquire each item of accurate data of the human body information.

Platform compensation unit 400 includes a linkage assembly 401, a third power assembly 402, and a third carriage assembly 403. Wherein, the third bracket assembly 403 is used for fixing and mounting the third power assembly 402; the third power assembly 402 is used to provide power to compensate for motion; the connecting assembly 401 is used for connecting the third power assembly 402 and the rotating assembly 201, and transmitting the output power of the third power assembly 402 to the rotating assembly 201, so as to perform compensatory adjustment on the inclination state of the rotating assembly 201. The lower end of the third power assembly 402 is fixed to the second moving unit 200 through the third bracket assembly 403, and the upper end of the third power assembly 402 is connected to the lower end surface of the rotating assembly 201 through the connecting assembly 401. The third power assembly 402 of the present invention is vertically disposed, and may be implemented by a member capable of performing linear telescopic motion, such as a servo electric cylinder, and the telescopic end of the third power assembly 402 faces upward.

Further, the connecting assembly 401 includes a first mating member 401a and a second mating member 401b, wherein the upper end of the first mating member 401a is embedded in the second mating member 401b, the lower end thereof encloses the upper end of the third power assembly 402, and the first mating member 401a is movable in all directions at the end of the third power assembly 402. Wherein the second fitting member 401b is connected with the rotating assembly 201.

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 third 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. The lower end face of the rotating component 201 is provided with an annular sliding groove 201a matched with the sliding part 401b-1, wherein the sliding part 401b-1 is a sliding block embedded in the annular sliding groove 201 a. In order to facilitate the relative stability of the second mating member 401b in the present invention, two sets of sliding portions 401b-1 may be provided, and the lower end surface of the rotating assembly 201 is also correspondingly provided with an inner annular sliding groove 201a and an outer annular sliding groove 201 a.

Further, the platform compensation units 400 are provided with at least three groups, and are uniformly distributed on a circumference of the lower layer of the rotating assembly 201. Each third power assembly 402 is secured to the peripheral member 204 by a third bracket assembly 403. When it is desired to adjust the rotating assembly 201 via the platform compensating unit 400, one (or two, three) of the third power assemblies 402 is activated to extend or shorten. When the horizontal rotation of the rotating component 201 is not considered, the second engaging element 401b is fixed to the lower side of the rotating component 201 through the sliding part 401b-1, so that it can be kept stationary relative to the rotating component 201, 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 201 in a manner similar to a "ball joint"), so that the third power component 402 can raise or lower the height of the rotating component 201 at this point through the control of the length thereof, and finally control the gradient of the rotating component 201. It should be noted here that: when one or two of the third power assemblies 402 are activated, it is possible to finely adjust the horizontal slope of the rotating assembly 201, and when three third power assemblies 402 are simultaneously activated, it is possible to finely adjust the vertical height of the rotating assembly 201 (coarse adjustment with respect to the first locomotion unit 100).

When considering the horizontal rotation of the rotating assembly 201, since the upper end of the second fitting part 401b has the sliding part 401b-1 fitted to the annular sliding groove 201a, when the third power assembly 402 is started, the connecting assembly 401 can support the rotating assembly 201, and the rotating assembly 201 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 201 and the vertical height thereof without affecting the horizontal rotation of the rotating assembly 201.

Referring to fig. 8 to 14, 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 first moving unit 100 is integrated and is connected with the second bracket assembly 203 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 203a through a bolt);

the other end of the first support 203a is connected with the second support 203b through a bolt;

the top of the first support 203a is bolted to the horizontal panel of the peripheral member 204.

The external wires S of the electric devices (including the first power assembly 102, the second power assembly 202, the information acquisition unit 300, and the like) in the present invention are uniformly laid inside the first supporting member 203a, and the first supporting member 203a in the present invention is a hollow box structure.

Because there are many internal circuits of the human body three-dimensional scanner, when an external power supply is needed to power on, all the wires S are uniformly laid and fixed on the bottom surface or the corners inside the first supporting member 203a for the convenience of the orderliness of the circuits and for preventing the external factors from damaging the circuits. But this also presents other problems:

because the human body three-dimensional scanner is large-scale equipment, the size and the mass of the human body three-dimensional scanner are large, and the human body three-dimensional scanner is not easy to move and carry, the human body three-dimensional scanner is designed into a detachable and assembled structure, and when the human body three-dimensional scanner needs to be carried at a long distance and a place is changed, and a merchant delivers goods, all units are detached and carried in batches, and finally are assembled uniformly. However, the disassembly of each functional unit results in a long and redundant wire attached to each unit, which is easily damaged during transportation. Therefore, the invention designs: 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 first section of the electric wire is defined as a first electric wire S-1, the short wire ends of all electric equipment are short in length and are detached together with the electric equipment, and the wire ends are short, so that inconvenience of carrying due to redundant electric wires is not influenced; the second wire is defined as a second wire S-2, which is a main line corresponding to each first wire S-1 and fixed in the box of the first support 203a for a long time. Therefore, based on the above, at the time of disassembly conveyance, the second electric wire S-2 is conveyed along with the first support member 203a case, and the first electric wire S-1 is conveyed along with other functional units. It should be noted that: the butt joint and the reassembly between the first wire S-1 and the second wire S-2 need to be performed by a quick and safe intermediate 'joint'. Therefore, the invention also provides a wiring mechanism J, which can quickly and conveniently connect the first electric wire S-1 and the second electric wire S-2, can be realized without tools and has the functions of sealing and water proofing.

The wiring mechanism J 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.

Further, the first end cap 601 and the second end cap 602 have the same main structure and are symmetrically disposed. The structures of the two are 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.

The main body of the tension member 603 is sleeve-shaped, and the front and rear ends thereof are connected to the first end cap 601 and the second end cap 602, respectively. 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. It should be noted that: the two ends of the closing assembly 500 are thin, the middle of the closing assembly is thick, and the cross section of the closing assembly 500 gradually increases from the end to the middle, and meanwhile, because the first end cap 601 and the second end cap 602 are respectively matched with the two end structures of the closing assembly 500 and are also in a variable cross section structure, when the first end cap 601 and the second end cap 602 are tightened, the inner side walls of the first end cap 601 and the second end cap 602 can inwardly extrude the first pressing piece 501b and the second pressing piece 502b, and finally extrude and compact the connection of the electric wire S.

The invention takes the first power assembly 102 as an example: the first power assembly 102 is connected with a first electric wire S-1, a second electric wire S-2 is laid in a first supporting piece 203a of the second bracket assembly 203, and a connecting end of the first electric wire S-1 and a connecting end of the second electric wire S-2 are respectively inserted into threading ports at two ends of the wiring mechanism J and are connected and fixed through the wiring mechanism J.

Therefore, other electric equipment can connect the first wire S-1 with the second wire S-2 through the wiring mechanism J and externally connect a power supply through the second wire S-2.
