Description

Technical Field

[0001] This application relates to the field of electromagnetic compatibility testing technology, and in particular to an electromagnetic compatibility testing device for smart glasses. Background Technology

[0002] Electromagnetic compatibility (EMC) refers to the ability of a device or system to operate within its electromagnetic environment without causing unacceptable electromagnetic interference to any other equipment in that environment. EMC includes two aspects: firstly, the electromagnetic interference generated by the device during normal operation must not exceed certain limits; secondly, the device must have a certain degree of immunity to electromagnetic interference present in its environment, i.e., electromagnetic susceptibility.

[0003] Because smart glasses contain various electronic components, some of which have magnetic permeability, they can disturb the magnetic field during testing. This is especially true when the smart glasses move or vibrate during testing, as these components can interfere with the results. The electromagnetic permeability of these electronic components is an inherent electromagnetic susceptibility of the smart glasses themselves; therefore, strengthening the mounting structure of the smart glasses during electromagnetic compatibility testing becomes a crucial issue. Utility Model Content

[0004] In order to strengthen the fixation structure of smart glasses during the electromagnetic compatibility testing process and reduce the impact of movement or shaking of smart glasses on the test results, this application provides an electromagnetic compatibility testing device for smart glasses.

[0005] The electromagnetic compatibility testing device for smart glasses provided in this application adopts the following technical solution:

[0006] An electromagnetic compatibility testing device for smart glasses includes a storage box for holding the glasses. Coils are symmetrically mounted at both ends of the storage box, with the axes of the two coils aligned on the same horizontal line. A detector with one end extending into the storage box is fixedly mounted on the side of the storage box adjacent to the coils. Two mounting plates are symmetrically slidably arranged inside the storage box, with a sliding structure between the mounting plates and the storage box. An elastic clamp is rotatably mounted on each mounting plate. The elastic clamp includes two symmetrically arranged clamping pieces and a base plate for connecting the two clamping pieces and located at the same end of the two clamping pieces. Bending areas are provided on the two clamping pieces, with the inner sides of the bending areas on the two clamping pieces close to each other.

[0007] By adopting the above technical solution, the temples of the smart glasses can be locked and fixed by the bending area on the clip. The sliding mounting plate is designed to be applicable to glasses of different widths, thereby improving the practicality of the testing equipment. In addition, the rotating connection between the mounting plate and the elastic clip is designed to prevent the test results from being affected by the rotation of the temples during the electromagnetic testing process.

[0008] Optionally, the storage box has an installation groove on its bottom side. The sliding structure includes a drive motor fixedly installed at one end of the installation groove and a bidirectional screw rod rotatably installed in the installation groove along its length. One end of the bidirectional screw rod is fixedly connected to the output shaft of the drive motor, and both installation discs are threaded onto the bidirectional screw rod. The two installation discs are symmetrically arranged on the bidirectional screw rod.

[0009] By adopting the above technical solution, the drive motor drives the bidirectional screw to rotate, thereby causing the two mounting plates threadedly connected to the bidirectional screw to move closer or further apart. This allows the temples of smart glasses of different widths to be fixed by adjusting the position of the mounting plates. The operation method and structure are simple, giving this device higher economic value.

[0010] Optionally, the mounting plate has a cross-sectional dimension larger than that of the mounting groove, and the mounting plate is movably disposed above the opening of the mounting groove.

[0011] By adopting the above technical solution, the installation plate will not collide with the installation slot or the storage box during the movement of the installation plate, so as to avoid damage to the smart glasses, improve the safety of the device during operation, and facilitate the elastic clip to fix the temples.

[0012] Optionally, the mounting plate is provided with an elastic limiting mechanism for controlling the rotation angle of the elastic clamp. The elastic limiting mechanism includes a limiting rod fixedly inserted vertically onto the base plate and several limiting loops elastically disposed circumferentially at the end of the limiting rod. The limiting loops can completely enter the interior of the limiting rod. A limiting groove is formed on the mounting plate. Several limiting blocks are integrally disposed circumferentially at the bottom of the limiting groove. The limiting blocks abut against one end of the limiting loops. A torsion spring is connected between the limiting rod and the inner wall of the limiting groove.

[0013] By adopting the above technical solution, the limiting rod and the base plate fixedly connected to the limiting rod can drive the entire elastic clamp to rotate in a certain direction on the mounting plate. When it rotates to a suitable angle, the limiting loop will abut against the limiting block under the action of the torsion spring, and the limiting block will abut against the limiting loop to restrict the rotation of the elastic clamp, so as to prevent the elastic clamp from rotating on its own during the detection process, which would make the clamping structure of the smart glasses not stable enough, and thus affect the accuracy of the detection results.

[0014] Optionally, the two ends of the limiting block along the axial direction of the limiting groove are arc-shaped structures, and the end of the limiting loop that abuts against the limiting loop on the limiting block is an arc-shaped structure that cooperates with the limiting block.

[0015] By adopting the above technical solution, the elastic clamp can be rotated in reverse manually, so that the smart glasses can be disassembled after the test is completed. The structure is simple and easy to operate, which improves the economic applicability of the testing equipment. It can also strengthen the structure of the limiting block and the limiting loop to prevent damage.

[0016] Optionally, the elastic clip is provided with an adjustment component that can adjust the elasticity of the elastic clip. The adjustment component includes a screw threaded through one end of the clip near the base plate. The end of the screw is threadedly connected to one of the clips. A spring is movably sleeved in the middle of the screw, and the two ends of the spring are fixedly connected to the screw and the clip.

[0017] By adopting the above technical solution, the elastic clamping force between the two clamping plates of the elastic clamp can be adjusted by screws to avoid the clamping effect of the elastic clamp weakening after repeated use of the elastic clamp and the tension spring.

[0018] Optionally, an elastic pad is provided on the inner side of the bending area, and when the elastic clip is not holding the glasses, the sides of the elastic pads on the two clips that are close to each other abut against each other.

[0019] By adopting the above technical solution, the temples of smart glasses can be protected to prevent wear and tear, while the vibration generated by the smart glasses during the operation of the testing equipment can be effectively reduced, thus improving the stability of the testing process.

[0020] Optionally, each of the two clips has a support piece integrally connected to the end away from the base plate. The support piece is tilted to the side away from the other clip, and the two support pieces are arranged symmetrically.

[0021] By adopting the above technical solution, it is more convenient to place the smart glasses to be tested into the clamping position, without having to find special equipment or manually separate the two clamps, thus improving the ease of operation of the testing equipment.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] This application strengthens the fixing structure of smart glasses in the testing equipment, which greatly improves the detection accuracy of smart glasses during electromagnetic testing.

[0024] This application can be adjusted according to the size of different smart glasses, providing operational flexibility and a wider range of applications. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0034] This application discloses an electromagnetic compatibility testing device for smart glasses.

[0035] Reference Figure 1 An electromagnetic compatibility (EMC) testing device for smart glasses includes a storage box 1 for holding the smart glasses to be tested and coils 2 symmetrically fixed on both sides of the storage box 1. The axes of the two coils 2 are on the same horizontal line, so that when the two coils 2 are energized, a magnetic field can penetrate the storage box 1, creating a magnetic field-filled environment inside the storage box 1. A detector 3 is provided on the side of the storage box 1 adjacent to both coils 2, with one end extending into the interior of the storage box 1, for detecting the EMC of the smart glasses when they are in a magnetic field.

[0036] Reference Figure 1 , Figure 2 and Figure 3 Furthermore, the storage box 1 contains two symmetrically sliding mounting plates 4, on which elastic clips 5 are rotatably mounted for holding the temples of the smart glasses. Each elastic clip 5 includes two symmetrically arranged clips 51, integrally connected by a base plate 52 located at the same end of each clip 51. Both clips 51 have an elastic force that pulls them closer together, causing their adjacent sides to press tightly together. To avoid excessive clamping force on the temples of the smart glasses, bending areas 511 are provided on the clips 51, and these bending areas 511 are symmetrically arranged. When the smart glasses are held in place by the clips 51, their temples are located within the annular area formed by the two bending areas 511.

[0037] Reference Figure 2 and Figure 3 Furthermore, to ensure that the electromagnetic compatibility testing equipment of this application can be applied to glasses of any shape and size, elastic pads 512 are fixedly installed on two closely spaced inner sides. The elastic pads 512 abut against the sides of the temples and form an elastic clamp 5. At the same time, the elastic pads 512 can also reduce the vibration amplitude of the smart glasses during equipment operation, improve the stability of the equipment during testing, and enhance the accuracy of the test results.

[0038] Preferably, when the two clips 51 are not holding the smart glasses, the two elastic pads 512 abut against each other on their closest sides to improve the compatibility of the elastic clips 5 with glasses of different temple sizes.

[0039] Reference Figure 3 Furthermore, each of the two clips 51 has an integral support piece 53 at the end furthest from the base plate 52. The two support pieces 53 are symmetrically arranged and tilted away from each other from the other clip 51, so as to make it easier to insert the temples of the smart glasses between the two clips 51 of the elastic clip 5, avoiding the difficult operation of manually prying the two clips 51 apart.

[0040] Reference Figure 1 and Figure 4 The storage box 1 has a mounting groove 11 at its bottom inner side. Inside the storage box 1 is a sliding structure 8 for driving two symmetrical mounting discs 4 to move closer or further apart. The sliding structure 8 includes a drive motor 81 fixedly mounted inside the mounting groove 11 at one end along its length, and a bidirectional screw 82 rotatably mounted inside the mounting groove 11 along its length. One end of the bidirectional screw 82 is fixedly sleeved onto the output shaft of the drive motor 81. The lower ends of the two mounting discs 4 have threaded holes 42 with opposite internal thread directions, and the two mounting discs 4 are symmetrically threaded onto the bidirectional screw 82.

[0041] Reference Figure 4 , Figure 5 and Figure 6 The mounting plate 4 is equipped with an elastic limiting mechanism 6 for controlling the rotation angle of the elastic clamp 5. This mechanism includes a limiting rod 61 fixedly inserted into the base plate 52 and several limiting loops 62 arranged circumferentially at the end of the limiting rod 61 away from the base plate 52. The limiting loops 62 are elastically connected to the limiting rod 61, and the limiting loops 62 can retract into the limiting rod 61. A limiting groove 41 is formed on the side of the mounting plate 4 near the base plate 52. Several limiting blocks 63 are integrally connected circumferentially to the side wall of the limiting groove 41 near the bottom. The limiting blocks 63 abut against one end of the limiting loops 62. A torsion spring 64 connects the limiting rod 61 to the side wall of the limiting groove 41 to achieve elastic restriction of the limiting rod 61.

[0042] It should be noted that the dimensions of the two mounting plates 4 along their cross-sections are larger than the dimensions of the mounting groove 11 along its cross-sections, so that the mounting plates 4 can slide against the inner bottom side wall of the storage box 1.

[0043] Reference Figure 5 and Figure 6 Furthermore, both the limiting block 63 and the limiting loop 62 that abuts against the limiting block 63 are arc-shaped structures, so that the limiting rod 61 can be reset under manual operation, thus preventing the elasticity of the torsion spring 64 from being too large and exceeding the elastic limit between the limiting loop 62 and the limiting rod 61.

[0044] Reference Figure 2 and Figure 7 The elastic clip 5 is equipped with an adjustment component 7 that can adjust the elastic force between the two clips 51 to prevent the elastic clip 5 from weakening after repeated use. This component includes a screw 71 threaded through one end of each clip 51 near the base plate 52, and a tension spring 72 connected to the middle of the screw 71, with both ends fixedly connected to the two clips 51. The tension spring 72 also increases the elastic clip 5's holding force.

[0045] The implementation principle of the electromagnetic compatibility testing device for smart glasses in this application is as follows:

[0046] When the smart glasses undergo electromagnetic compatibility testing, the two temples are respectively placed into the bending area 511 between the two clips 51 inside the two elastic clips 5 on the two mounting plates 4 to fix the temples. The elastic clips 5 on the mounting plates 4 can rotate to adapt to temples with different degrees and shapes of bending. At the same time, the width between the two mounting plates 4 can be adjusted by the bidirectional screw 82 to ensure stable clamping for smart glasses of different widths.

[0047] When the elastic clip 5 is used multiple times and its holding force decreases, the screws 71 located on the two clips 51 can be rotated to move them away from each other, thereby changing the elastic tension on the tension spring 72 and indirectly adjusting and restoring the elastic force of the elastic clip 5.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
