Detailed Description
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is apparent that the embodiments described below are only some embodiments of the present invention, not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In the description of the present invention, it will be understood that when one component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components may also be present. When an element is referred to as being "disposed on" another element, it can be directly on the other element or intervening elements may also be present.
Furthermore, the terms "long," "short," "inner," "outer," and the like, as used herein, refer to an orientation or positional relationship based on that shown in the drawings, for convenience of description of the present invention, and are not intended to indicate or imply that the apparatus or elements referred to must have this particular orientation, operate in a particular orientation configuration, and thus should not be construed as limiting the invention.
The wake-up distance and the sleep distance are collectively referred to as a detection distance of the electronic device, and a distance detection component generally includes a magnet and a hall sensor separately disposed on the screen and the host. According to the association standard, the sleep distance of the electronic device is required to be larger than 20mm, and the wake-up distance is required to be smaller than 100mm. In the prior art, the magnetic flux of the magnet is reduced to meet the requirement that the awakening distance is smaller than 100mm, but the magnetic flux of the magnet is too small to ensure that the sleeping distance is larger than 20mm, and even the bad phenomenon that the cover is closed and the screen is not closed can occur, so that the detection distance of the electronic equipment needs to be simulated during production to determine whether the requirements are met.
Although the detection distance can be simulated by a magnetic field analysis method to be applied to the electronic equipment products, the actual detection distance is inconsistent with the simulated detection distance due to the fact that the tolerance exists in the magnet technology and the introduction of the theoretical simulation, so that the actual detection distance exceeds the standard, and the actual requirement is not met.
In order to solve the foregoing problems, the present invention provides a detection distance testing scheme for an electronic device, and the technical scheme of the present invention is further described below by taking a notebook computer as an example, and referring to the accompanying drawings and through specific embodiments.
Example 1
Referring to fig. 1 and fig. 2 in combination, an embodiment of the present invention provides a method for testing a detection distance of an electronic device, and provides a screen opening/closing simulation mechanism 10, where the screen opening/closing simulation mechanism 10 includes: a first rotating portion 11 provided with a magnetic element 111; a second rotating portion 12 provided with a hall element 121; the first rotating part 11 and the second rotating part 12 are connected by a rotating member such that the first rotating part 11 can be driven to rotate relative to the second rotating part 12.
In this embodiment, the test method includes:
S1, in the magnetic field functional region formed by the magnetic element 111, the first rotating portion 11 and the second rotating portion 12 are rotated relatively until the magnetic flux acting on the hall element 121 changes to the switching trigger threshold value of the hall element 121.
It can be understood that in the present embodiment, the first rotating portion 11 is regarded as a screen of the notebook computer, the second rotating portion 12 is regarded as a host of the notebook computer, the first rotating portion 11 is opened relative to the second rotating portion 12 to simulate a screen opening motion of the notebook computer, and the first rotating portion 11 is closed relative to the second rotating portion 12 to simulate a screen closing motion of the notebook computer.
Specifically, the switching trigger threshold of the hall element 121 includes a wake-up threshold and a sleep threshold, and when the magnetic flux passing through the hall element 121 reaches the wake-up threshold or the sleep threshold, the level state output from the hall element 121 is switched.
Based on this, in step S1, the first rotating portion 11 and the second rotating portion 12 are rotated relatively until the magnetic flux acting on the hall element 121 changes to the switching trigger threshold value of the hall element 121, and the method includes:
Opening the first rotary part 11 with respect to the second rotary part 12 until the magnetic flux passing through the hall element 121 changes to a wake-up threshold value; or, during the opening process, the magnetic flux passing through the hall element 121 gradually decays, and reaches the wake-up threshold value when decaying to the induction lower limit value of the hall element 121.
Closing the first rotating portion 11 with respect to the second rotating portion 12 until the magnetic flux passing through the hall element 121 changes to the sleep threshold value; during the closing process, the magnetic flux passing through the hall element 121 gradually increases, and when the induction upper limit value of the hall element 121 is increased, the sleep threshold value is reached.
When the magnetic flux passing through the hall element 121 reaches the wake-up threshold value, the hall element 121 is switched from low level to high level, so as to simulate the wake-up action of the notebook computer in the process of opening the screen; when the magnetic flux passing through the hall element 121 reaches the sleep threshold value, the hall element 121 is switched from high level to low level, so as to simulate the sleep action of the notebook computer in the process of closing the screen.
It can be understood that the rotating member is a rotating shaft, and the rotating shaft can rotate relative to the second rotating portion 12 and drives the first rotating portion 11 to rotate when rotating; the rotation of the shaft can be achieved by driving the motor.
S2, when the magnetic flux acting on the hall element 121 changes to the switching trigger threshold value of the hall element 121, the relative distance between the reference positions on the first rotating portion 11 and the second rotating portion 12 is acquired.
In the process of opening the first rotating part 11 relative to the second rotating part 12, when the magnetic flux acting on the hall element 121 changes to the switching trigger threshold value of the hall element 121, the acquired relative distance between the reference positions on the first rotating part 11 and the second rotating part 12 is the wake-up distance for triggering the notebook computer to wake up;
In the process of closing the first rotating part 11 relative to the second rotating part 12, when the magnetic flux acting on the hall element 121 changes to the switching trigger threshold value of the hall element 121, the obtained relative distance between the reference positions on the first rotating part 11 and the second rotating part 12 is the sleep distance for triggering the sleep of the notebook computer.
The reference positions on the first rotating part 11 and the second rotating part 12 can be determined according to the requirement, specifically, the positions corresponding to the simulated front edge of the notebook computer, so that the detection distance of the notebook computer can be simulated.
It will be appreciated that the reference positions may be located on the first rotating part 11 and the second rotating part 12, or may be located on an extension line of the first rotating part 11 and the second rotating part 12, and the specific positions may be determined according to the specific size of the notebook computer, and the reference positions on the first rotating part 11 and the second rotating part 12 are obtained based on similar triangles. In particular, a distance measuring element, which may be a laser distance measuring device, may be provided at the reference position for acquiring the relative distance between the reference positions on the first rotary part 11 and the second rotary part 12.
And S3, judging whether the relative distance meets the preset standard distance condition, and obtaining a judging result.
Specifically, in step S3:
When the magnetic flux passing through the hall element 121 reaches the wake-up threshold value, judging whether the relative distance satisfies a preset wake-up distance condition; and when the relative distance is smaller than or equal to a preset awakening distance threshold value, a preset awakening distance condition is met.
When the magnetic flux passing through the hall element 121 reaches the sleep threshold value, it is judged whether the relative distance satisfies a preset sleep distance condition; and when the relative distance is greater than or equal to a preset dormancy distance threshold value, a preset dormancy distance condition is met.
Further, when the relative distance satisfies a preset wake-up distance condition, and when the relative distance satisfies a preset sleep distance condition, the current relative distance, the magnetic flux passing through the hall element 121, and the operating voltage of the hall element 121 are recorded, respectively, so as to be applied to a notebook computer product.
Specifically, a distance measuring element, which may be a laser distance meter, is provided on the first rotating part 11 or the second rotating part 12, for acquiring a relative distance between reference positions on the first rotating part 11 and the second rotating part 12.
Meanwhile, a voltmeter and a gaussmeter are connected to the hall element 121 to achieve acquisition of the magnetic flux passing through the hall element 121 and the operating voltage of the hall element 121.
Referring to fig. 3, further, the method for testing a detection distance of an electronic device according to the present embodiment further includes:
S4, adjusting the unit change amount of the magnetic flux acting on the hall element 121 when the first rotating portion 11 and the second rotating portion 12 are rotated relative to each other according to the determination result.
As can be appreciated, the amount of change in magnetic flux acting on the hall element 121 is specifically: the amount of change in magnetic flux per unit displacement during rotation of the first rotating portion 11 relative to the second rotating portion 12.
Referring to fig. 4, specifically, the amount of change in the magnetic flux passing through the hall element 121 can be adjusted by:
S41, adjusting the distance between the mounting positions of the magnetic element 111 and the hall element 121 and the rotation axis to adjust the amount of change in magnetic flux acting on the hall element 121.
For example, when the first rotating portion 11 is opened with respect to the second rotating portion 12 and the magnetic flux passing through the hall element 121 reaches the wake-up threshold value, if the relative distance is greater than the preset wake-up distance threshold value, the mounting positions of the magnetic element 111 and the hall element 121 are adjusted in a direction away from the rotation axis, so as to increase the amount of change in the magnetic flux passing through the hall element 121 during the opening.
Similarly, the first rotating portion 11 is closed relative to the second rotating portion 12, and if the relative distance is smaller than the preset sleep distance threshold when the magnetic flux passing through the hall element 121 reaches the sleep threshold, the mounting positions of the magnetic element 111 and the hall element 121 are adjusted in a direction away from the rotation axis, so as to increase the amount of change in the magnetic flux passing through the hall element 121 during the opening process.
It is understood that the distances between the magnetic element 111 and the hall element 121 and the rotation axis may be equal or unequal; in this embodiment, a case where the distances between the magnetic element 111 and the hall element 121 and the rotation axis are equal will be described as an example.
Further, slide rails for mounting the magnetic element 111 and the hall element 121 may be provided on the first rotating portion 11 and the second rotating portion 12, respectively, so as to achieve positional adjustment of the magnetic element 111 and the hall element 121; meanwhile, graduations may be provided corresponding to the extending direction of the guide rail so as to obtain distances between the magnetic element 111 and the hall element 121, respectively, and the rotation shaft.
In one alternative embodiment, a set of magnetic elements 111 and hall elements 121 may be provided for the opening and closing actions of the first rotating portion 11 with respect to the second rotating portion 12, and magnetic fluxes of the magnetic elements 111 and induction parameters of the hall elements 121 may be provided, respectively, so as to acquire distance data between the two sets of magnetic elements 111 and hall elements 121 and the rotating shaft.
In another alternative embodiment, the opening and closing actions of the first rotating part 11 relative to the second rotating part 12 are implemented by using the same set of magnetic elements 111 and hall elements 121, and distance data between one magnetic element 111 and hall element 121 and the rotating shaft are obtained during the opening and closing test, and then a weighted average of the two distance data is taken as data finally applied to the notebook computer product.
Further, in the present embodiment, the magnetic element 111 is a magneto coil; the magnetic field intensity in the magnetic field functional area can be flexibly adjusted by using the magnetic generating coil so as to simulate different types of magnets. Generally, the magnet proofing period is 7-14 days, and the magnet is replaced by the magnet generating coil in the embodiment, so that the magnet proofing step can be omitted, the testing time period is shortened, and the production progress is ensured.
Referring to fig. 5, based on this, the test method provided in the present embodiment further includes:
s01, controlling the magnetic element 111 to generate target magnetic flux to form a magnetic field functional area.
In this step, the magnetic field functional region is formed by controlling the current through the magnetic element 111 so that the magnetic element 111 generates a target magnetic flux.
Further, in step S4, the amount of change in magnetic flux acting on the hall element 121 may be adjusted by:
Referring to fig. 6, S42, the current through the magnetic element 111 is adjusted to increase or decrease the target magnetic flux.
It will be appreciated that steps S41 and S42 may be used simultaneously to effect adjustment of the amount of change in magnetic flux through the hall element 121, or one implementation may be adopted.
For example, when the mounting positions of the magnetic element 111 and the hall element 121 are fixed, the current passing through the magnetic element 111 may be adjusted by step S42 until the relative distance satisfies a preset standard distance condition, thereby obtaining an optimal target magnetic flux, and customizing a magnet applied to a notebook computer based on the target magnetic flux;
When the magnet model applied to the notebook computer is fixed, the distance between the installation positions of the magnetic element 111 and the hall element 121 and the rotation axis can be adjusted through step S41 until the relative distance satisfies a preset standard distance condition, thereby obtaining the optimal installation positions of the magnetic element 111 and the hall element 121, and installing the magnet and the hall sensor in the notebook computer based on the installation positions.

The rotating member is a rotating shaft, and the rotating shaft can rotate relative to the second rotating part 12 and drives the first rotating part 11 to rotate when rotating; the rotation of the shaft can be achieved by driving the motor. The control unit 20 is used for controlling the start and stop of the motor and the rotation direction so as to enable the first rotating part 11 and the second rotating part 12 to rotate relatively.
Specifically, the control unit 20 is further configured to:
Opening the first rotating part 11 with respect to the second rotating part 12 until the magnetic flux passing through the hall element 121 reaches the wake-up threshold value; the first rotating portion 11 is closed with respect to the second rotating portion 12 until the magnetic flux passing through the hall element 121 reaches the sleep threshold value.
It is understood that the control unit 20 may open or close the first rotating part 11 with respect to the second rotating part 12 by controlling the rotation direction of the motor.
