[0022] The following will be combined with the attached examples of the present application Figure 1 To Attachment Fig.11 , the technical solutions in the embodiments of the present application are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.
[0023] The present application provides a testing tool.
[0024] Specifically, the test tooling provided in the present application is applied to the testing of eyewear products. The test tooling is mainly used to simulate eyewear products with different specifications and parameters so as to achieve the wearing comfort test of the eyewear products through the test tooling.
[0025] Among them, the eyewear products can be VR glasses, Bluetooth glasses, camera glasses and other smart glasses.
[0026] Please refer to Figure 1 and Figure 2 , Figure 1 A schematic diagram of the structure of the test tool provided in the embodiment of the present application, Figure 2 An exploded schematic diagram of a test fixture provided for an embodiment of the present application. In an embodiment of the present application, the test fixture 10 includes a first bracket 100, a second bracket 200, a first wearing portion 310, and a second wearing portion 320. Among them, the second bracket 200 is slidably connected to the first bracket 100, and the second bracket 200 can slide relative to the first bracket 100 to move closer to or away from the first bracket 100. The first wearing portion 310 is connected to the first bracket 100, and the second wearing portion 320 is connected to the second bracket 200 and is arranged opposite to the first wearing portion 310. The second wearing portion 320 and the first wearing portion 310 are used to cooperate with each other and be worn on the human ear.
[0027] In the description of this application, it should be understood that terms such as "first" and "second" are only used to distinguish similar objects and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.
[0028] Among them, the first bracket 100 and the second bracket 200 are used as a whole to simulate the frame part of the eyeglass product (or the structural part that realizes the main function of the eyeglass product), and the whole connected by the first bracket 100 and the second bracket 200 is used to be installed in front of the human eye under the connection action of the first wearing part 310 and the second wearing part 320.
[0029] The first bracket 100 and the second bracket 200 may be in a frame shape or in a solid block shape. The first bracket 100 and the second bracket 200 may be designed with a symmetrical structure to accurately simulate the structure of the eyeglass product.
[0030] It is understandable that the first bracket 100 and the second bracket 200 can be configured to have a reasonable weight as a whole, so as to more accurately and realistically simulate the wearing of eyewear products on the human body. The first bracket 100 and the second bracket 200 are made of the same material, and the material of the first bracket 100 and the second bracket 200 can be metal or plastic.
[0031] Optionally, in some optional embodiments, in order to simulate some special eyewear products, the materials used to prepare the first bracket 100 and the second bracket 200 may also be different.
[0032] The first wearing portion 310 and the second wearing portion 320 are used to simulate the temple portion of the eyeglass product (or the structural portion that realizes the wearing function of the eyeglass product). The first wearing portion 310 and the second wearing portion 320 are respectively wearably matched with the left and right ears of the human body, so that the first bracket 100 and the second bracket 200 are located in front of the human eye. It can be understood that the first wearing portion 310 and the second wearing portion 320 can be ergonomically designed according to the contour shape of the human ear, so that the first wearing portion 310 and the second wearing portion 320 can be stably worn on the human ear, while improving the wearing comfort.
[0033] For example, in one embodiment, Figure 1 As shown, both the first wearing portion 310 and the second wearing portion 320 may be temples.
[0034] The first bracket 100 is slidably connected to the second bracket 200, so that the first bracket 100 and the second bracket 200 can be moved closer to or farther away from each other, thereby driving the first wearing portion 310 and the second wearing portion 320 to be moved closer to or farther away from each other. Then, the relative distance between the first wearing portion 310 and the second wearing portion 320 can be adjusted, thereby simulating the wearing conditions of the two temple parts of the eyeglass product at different widths.
[0035] The test fixture 10 of the present application, the first bracket 100 and the second bracket 200 are connected, the first wearing part 310 and the second wearing part 320 are respectively connected to the first bracket 100 and the second bracket 200, the first wearing part 310 and the second wearing part 320 are used to cooperate with each other to be worn on the human ear, and the first bracket 100 and the second bracket 200 are located in front of the human eye, which can simulate the situation of the eyewear product being worn on the human body. The present application sets a first bracket 100 and a second bracket 200 in sliding connection, and the first bracket 100 and the second bracket 200 can be close to or away from each other, and at the same time drive the first wearing part 310 and the second wearing part 320 to be close to or away from each other, so that the relative distance between the first wearing part 310 and the second wearing part 320 can be adjusted, and the wearing comfort test of the two temple parts of the simulated eyeglass product at different widths can be realized, and then the structural design of the eyeglass product can be confirmed or adjusted according to the test results. The present application performs simulation testing through the test tool 10, so that there is no need to manufacture actual test products of the eyeglass product during the research and development process. The test tool 10 is much simpler than the structure of the eyeglass product and can be adjusted to realize multiple tests, which can greatly reduce the product development cycle and research and development cost.
[0036] Specifically, in the process of testing the wearing comfort of the test tool 10 simulating the eyewear product at different widths, the wearing comfort can be measured through the tester's intuitive feeling, or through specific test data such as the clamping force of the first wearing part 310 and the second wearing part 320 and the human ear.
[0037] Exemplarily, in one embodiment, the test fixture 10 further includes a detection element (not shown in the figure). The detection element is attached between the wearing portion and the human ear to measure the clamping force between the wearing portion and the human ear.
[0038] Specifically, one detection element may be provided, and the detection element is used to be attached between one of the wearing parts and the human ear, for example, it may be attached between the first wearing part 310 and the human ear, or it may be attached between the second wearing part 320 and the human ear. Two detection elements may also be provided, and one detection element may be provided between each wearing part and the human ear.
[0039] Exemplarily, in one embodiment, the number of detection elements is two, one of which is attached to the side of the first wearing portion 310 facing the second wearing portion 320, and the other is attached to the side of the second wearing portion 320 facing the first wearing portion 310. Then, one of the detection elements can detect the clamping force between the first wearing portion 310 and one of the ears of the human body, and the other detection element can detect the clamping force between the second wearing portion 320 and the other ear of the human body. In general, the clamping force values measured by the two detection elements are the same or the difference is very small. When the clamping force values measured by the two detection elements differ greatly, it means that one of the detection elements is abnormal, such as damaged, and needs to be replaced. By setting two detection elements to measure and obtain two clamping force data, and comparing the two clamping force data, the status of the two detection elements can be determined, which can prevent the inaccurate clamping force data from being measured due to failure to detect damage to the detection elements.
[0040] The detection element may be a pressure sensor, for example, a strain gauge pressure sensor, a piezoresistive pressure sensor, or a piezoelectric pressure sensor.
[0041] The detection element may be connected to a terminal such as a computer for communication so as to transmit the clamping force data to the terminal.
[0042] Optionally, in one embodiment, the detection element can also be configured with a wireless module to achieve wireless communication with the terminal, and each detected clamping force data can be wirelessly transmitted to the terminal. Compared with information transmission through a data cable connection, the data cable can be prevented from affecting the wearing of the test tool 10.
[0043] Optional, please combine Figure 1 And refer to Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the structure of the support base of the test fixture of the embodiment of the present application. Figure 4 Schematic diagram of the structure of the screw rod of the test fixture of the embodiment of the present application. In one embodiment, the test fixture 10 includes a support seat 400 and a screw rod 500.
[0044] The support base 400 is connected to the first bracket 100 and the second bracket 200, and the support base 400 is provided with a slide groove 410. The screw rod 500 includes a first threaded portion 520 and a knob portion 510 connected to the first threaded portion 520, the first threaded portion 520 is threadedly connected to one of the first bracket 100 and the second bracket 200, and the knob portion 510 is used to drive the first threaded portion 520 to rotate under the action of an external force, so as to drive one of the first bracket 100 and the second bracket 200 to slide relative to the other along the slide groove 410.
[0045] Specifically, the tester can apply force by hand to drive the knob portion 510 to rotate, which can drive the first threaded portion 520 of the screw 500 to rotate, thereby driving the first bracket 100 or the second bracket 200 to slide through the force transmission of the thread, so that the first bracket 100 and the second bracket 200 are close to or away from each other, and then the distance between the first wearing portion 310 and the second wearing portion 320 can be adjusted. It can be understood that by setting the knob portion 510, a better force application position is provided on the screw 500, so that the tester can apply force to drive the screw 500 to rotate, thereby facilitating the adjustment of the distance between the first wearing portion 310 and the second wearing portion 320, improving the operability of the test tool 10, and facilitating the use of the tester.
[0046] Optionally, the outer diameter of the knob portion 510 may be greater than the outer diameter of the first threaded portion 520 to further facilitate the tester to apply force.
[0047] Normally, in order to simulate the wearing comfort test of the two temple parts of the eyeglass product at different widths, the distance between the first wearing part 310 and the second wearing part 320 is gradually adjusted, and the distance increased or decreased each time is small, that is, the sliding distance of the first bracket 100 or the second bracket 200 each time is small. In this embodiment, the first threaded portion 520 of the screw 500 drives the first bracket 100 or the second bracket 200 to slide, which makes it easier to achieve fine-tuning of the distance, and can facilitate the tester to adjust and control the sliding distance of the first bracket 100 or the second bracket 200, further facilitating the tester to use.
[0048] In addition, the first threaded portion 520 of the screw 500 has a self-locking capability. When not affected by external force, the screw 500 can limit the first bracket 100 and the second bracket 200, so that the first bracket 100 and the second bracket 200 can maintain their current positions after adjustment, preventing the first bracket 100 and the second bracket 200 from sliding relative to each other due to the tester shaking his head or nodding, and preventing the distance between the first wearable portion 310 and the second wearable portion 320 from changing, thereby ensuring the accuracy and reliability of the test results.
[0049] Optional, please combine Figure 1 , Figure 3 , Figure 4 And refer to Figures 5 to 7 , Figure 5 This is a front view of the test tool provided in the embodiment of the present application. Figure 6 for Figure 5 The cross-sectional view of the test fixture along section AA, Figure 7 for Figure 6A partial enlarged view of the B in the middle. In one embodiment, the screw rod 500 further includes a second threaded portion 530, the first threaded portion 520 and the second threaded portion 530 are respectively connected to opposite sides of the knob portion 510, the first threaded portion 520 is threadedly connected to the first bracket 100, the second threaded portion 530 is threadedly connected to the second bracket 200, and the first threaded portion 520 and the second threaded portion 530 have opposite thread rotation directions. The knob portion 510 is used to drive the first threaded portion 520 and the second threaded portion 530 to rotate synchronously under external force, so as to drive the first bracket 100 and the second bracket 200 to slide synchronously in opposite directions along the slide groove 410.
[0050] Then, this embodiment also sets the second threaded portion 530, so that the first bracket 100 and the second bracket 200 are both threadedly connected to the screw 500. When the knob portion 510 is rotated by an external force, the screw 500 can drive the first bracket 100 and the second bracket 200 to move synchronously. In addition, this embodiment also sets the first threaded portion 520 and the second threaded portion 530 to have opposite rotation directions, so that the screw 500 can drive the first bracket 100 and the second bracket 200 to move synchronously in opposite directions, which can better adjust the relative distance between the first wearing portion 310 and the second wearing portion 320.
[0051] The first threaded portion 520 and the second threaded portion 530 are configured to have the same thread pitch and thread diameter, so that the first bracket 100 and the second bracket 200 move synchronously by the same distance.
[0052] Specifically, in one embodiment, when the knob portion 510 rotates clockwise under the action of an external force, the screw 500 drives the first bracket 100 and the second bracket 200 to move toward each other synchronously, so that the first bracket 100 and the second bracket 200 are close to each other, which can reduce the relative distance between the first wearing portion 310 and the second wearing portion 320. When the knob portion 510 rotates counterclockwise under the action of an external force, the screw 500 drives the first bracket 100 and the second bracket 200 to move away from each other synchronously, so that the first bracket 100 and the second bracket 200 are away from each other, which can increase the relative distance between the first wearing portion 310 and the second wearing portion 320.
[0053] In practical applications, the first bracket 100 may be provided with a first threaded hole 1112 matched with the first threaded portion 520, and the first threaded hole 1112 and the slide groove 410 extend in the same direction. Similarly, the second bracket 200 may be provided with a second threaded hole 2112 matched with the second threaded portion 530, and the second threaded hole 2112 and the slide groove 410 extend in the same direction. Moreover, the first bracket 100 may be provided with a first slide rail 1111 matched with the slide groove 410, and the first slide rail 1111 is slidably inserted in the slide groove 410, so that the first bracket 100 slides along the slide groove 410 through the first slide rail 1111; the second bracket 200 may be provided with a second slide rail 2111 matched with the slide groove 410, and the second slide rail 2111 is slidably inserted in the slide groove 410, so that the second bracket 200 slides along the slide groove 410 through the second slide rail 2111.
[0054] Optional, please refer to Figure 3 The support seat 400 is provided with a limiting groove 420 for the knob portion 510 to rotate.
[0055] By providing the limiting groove 420 on the support base 400, the knob portion 510 is at least partially located in the limiting groove 420, so as to prevent the knob portion 510 from interfering with the support base 400 when rotating. Moreover, the limiting groove 420 can limit the knob portion 510, prevent the knob portion 510 from moving horizontally, and ensure that the screw rod 500 always rotates at a fixed position under the action of external force.
[0056] Exemplarily, in one embodiment, the limiting groove 420 is disposed in the middle of the support base 400. By disposing the limiting groove 420 in the middle of the support base 400, it can be ensured that the knob portion 510 is always in the middle of the support group, so that the first bracket 100 and the second bracket 200 always slide synchronously in opposite directions relative to the center line (or axis of symmetry) of the test fixture 10.
[0057] Please combine Figure 1 And refer to Figure 8 , Figure 8 Schematic diagram of the structure of the first bracket of the test fixture of the embodiment of the present application. In one embodiment, the first bracket 100 includes a first bracket body 110 and a first connecting arm 120. The first bracket body 110 includes a first support arm 111, the first support arm 111 extends along a first direction, and the first support arm 111 can slide relative to the second bracket 200 along the first direction. The first connecting arm 120 extends along a second direction and is connected to the first bracket body 110 at one end and connected to the first wearing portion 310 at the other end, and the second direction intersects with the first direction.
[0058] The second direction may be perpendicular to the first direction, so that the first connecting arm 120 and the first support arm 111 are arranged at 90°; the second direction may also be obliquely intersected with the first direction, so that the first connecting arm 120 and the first support arm 111 are arranged at an acute angle or an obtuse angle.
[0059] Exemplarily, in some embodiments, the angle formed by the first connecting arm 120 and the first support arm 111 is less than 90°, that is, the second direction intersects the first direction at an angle, so that the first connecting arm 120 can be tilted toward the center line of the test tool 10, so that the test tool 10 can be better worn on the human body.
[0060] The first slide rail 1111 may be disposed on the first arm 111 , and the first arm 111 is slidably connected to the support seat 400 via the first slide rail 1111 , so that the first arm 111 can slide relative to the second bracket 200 along the first direction.
[0061] Specifically, in actual applications, the first bracket body 110 and the first connecting arm 120 can be fixedly connected by screws, that is, the first bracket 100 is composed of two independent structures, the first bracket body 110 and the first connecting arm 120. Compared with the first bracket 100 as a whole, the structures of the first bracket body 110 and the first connecting arm 120 are relatively simple, and it is relatively easier to produce and process them separately, which is conducive to the production of the first bracket 100.
[0062] Optionally, in other optional embodiments of the present application, the first bracket body 110 and the first connecting arm 120 may also be integrally formed.
[0063] Please combine Figure 1 refer to Fig. 9 , Fig. 9 Schematic diagram of the structure of the second bracket of the test fixture of the present application embodiment. In one embodiment, the second bracket 200 includes a second bracket body 210 and a second connecting arm 220. The second bracket body 210 includes a second arm 211, and the second arm 211 extends along the first direction. The second arm 211 can slide relative to the first bracket 100 along the first direction. The second connecting arm 220 extends along a third direction and is connected to the second bracket body 210 at one end and connected to the second wearing portion 320 at the other end. The third direction intersects with the first direction.
[0064] The third direction may be perpendicular to the first direction, so that the second connecting arm 220 and the second support arm 211 are arranged at 90°; the third direction may also be obliquely intersected with the first direction, so that the second connecting arm 220 and the second support arm 211 are arranged at an acute angle or an obtuse angle.
[0065] Exemplarily, in some embodiments, the angle formed by the second connecting arm 220 and the second supporting arm 211 is less than 90°, that is, the third direction intersects obliquely with the first direction, so that the second connecting arm 220 can also be inclined toward the center line of the test fixture 10, so that the test fixture 10 can be better worn on the human body. Further, the angle formed by the second connecting arm 220 and the second supporting arm 211 is the same as the angle formed by the first connecting arm 120 and the first supporting arm 111, so that the second connecting arm 220 and the first connecting arm 120 are symmetrically arranged about the center line of the test fixture 10.
[0066] The second slide rail 2111 may be disposed on the second arm 211 , and the second arm 211 is slidably connected to the support seat 400 via the second slide rail 2111 , so that the second arm 211 can slide relative to the first bracket 100 along the first direction.
[0067] Specifically, in actual applications, the second bracket body 210 and the second connecting arm 220 can be fixedly connected by screws, that is, the second bracket 200 is composed of two independent structures, the second bracket body 210 and the second connecting arm 220. Compared with the second bracket 200 as a whole, the structures of the second bracket body 210 and the second connecting arm 220 are relatively simple, and it is relatively easier to produce and process them separately, which is conducive to the production of the second bracket 200.
[0068] Optionally, in other optional embodiments of the present application, the second bracket body 210 and the second connecting arm 220 may also be integrally formed.
[0069] It is understandable that in order to simulate the eyewear product more realistically and accurately, the test fixture 10 may be weighted.
[0070] For example, please combine Figure 1 And refer to Fig.10 The test fixture 10 includes a first counterweight assembly 610. The number of the first counterweight assembly 610 can be one or more, and the first counterweight assembly 610 is used to be arranged at a specific position of the first bracket 100 and / or the second bracket 200 to simulate the actual weight and center of gravity position of the eyewear product.
[0071] Specifically, different types of eyewear products generally adopt different structural designs to achieve their respective different usage functions. Accordingly, the overall weight and center of gravity of different eyewear products are different. Therefore, the specific number and location of the first counterweight assembly 610 need to be set according to the design requirements of the eyewear product simulated by the test fixture 10.
[0072] Optionally, in some embodiments, the first counterweight assembly 610 may be disposed on at least one of the first support arm 111 and the first connecting arm 120 .
[0073] Specifically, when the weight of the eyewear product simulated by the test requires that the test fixture 10 only needs to be equipped with one first counterweight assembly 610, the first counterweight assembly 610 can be set on the first arm 111 according to the center of gravity required by the test, or the first counterweight assembly 610 can be set on the first connecting arm 120. When the weight of the eyewear product simulated by the test requires that the test fixture 10 needs to be equipped with multiple first counterweight assemblies 610, all of the multiple first counterweight assemblies 610 can be set on the first arm 111 according to the center of gravity required by the test, or all of the multiple first counterweight assemblies 610 can be set on the first connecting arm 120, or some of the first counterweight assemblies 610 can be set on the first arm 111, and the other part of the first counterweight assemblies 610 can be set on the first connecting arm 120. It should be noted that the "multiple" mentioned herein includes two or more.
[0074] Optionally, in other embodiments, the first counterweight assembly 610 may be disposed on at least one of the second support arm 211 and the second connecting arm 220 .
[0075] Similarly, when the weight of the eyewear product simulated by the test requires that the test fixture 10 only needs to be equipped with one first counterweight assembly 610, the first counterweight assembly 610 can be set on the second arm 211 according to the center of gravity required by the test, or the first counterweight assembly 610 can be set on the second connecting arm 220. When the weight of the eyewear product simulated by the test requires that the test fixture 10 needs to be equipped with multiple first counterweight assemblies 610, all of the multiple first counterweight assemblies 610 can be set on the second arm 211 according to the center of gravity required by the test, or all of the multiple first counterweight assemblies 610 can be set on the second connecting arm 220, or some of the first counterweight assemblies 610 can be set on the second arm 211 and the other part of the first counterweight assemblies 610 can be set on the second connecting arm 220.
