Description

Technical Field

[0001] This utility model belongs to the field of mobile phone testing technology, specifically a positioning device for mobile phone coupling testing. Background Technology

[0002] Mobile phone coupling test is a test method used to evaluate the wireless performance of mobile phones. As a wireless communication device, the ability of a mobile phone to receive and transmit signals directly determines the communication quality. Through coupling test, the performance of a mobile phone under different frequency bands, signal strengths and complex environments can be detected, and its wireless performance, including antenna efficiency, transmit power and receive sensitivity, can be evaluated.

[0003] However, the following problems were found in the implementation of the relevant technologies:

[0004] First, many existing positioning devices for mobile phone coupling testing rely on manual operation to clamp the phone, which is not only cumbersome and time-consuming, but also prone to operator fatigue when testing a large number of phones, resulting in low testing efficiency. Furthermore, the clamping structure of existing positioning devices is relatively fixed, making it difficult to stably clamp phones of different sizes and shapes. Second, most coupling testing devices are not convenient for adjusting the distance between the phone and the coupling plate, and may only support simple manual adjustment, making it impossible to precisely adjust the coupling plate to the required height. This makes it difficult to meet diverse testing needs when testing the coupling effect of phones at different distances, resulting in incomplete and inaccurate test data. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 4 As shown, this utility model provides a positioning device for mobile phone coupling testing, including a base plate 1. A bracket 4 and an adjustment frame 2 are fixedly mounted on the upper surface of the base plate 1. A coupling test plate 3 is mounted on one side of the adjustment frame 2. A gear 44 is rotatably mounted on the upper surface of the bracket 4. A carrier plate 41 is mounted on the upper side of the bracket 4, and clamping plates 42 are symmetrically mounted on the upper surface of the carrier plate 41. A servo motor 43 is mounted between the bracket 4 and the carrier plate 41, and the output end of the servo motor 43 is fixedly connected to the gear 44. Tooth plates 45 are symmetrically meshed on both sides of the outer surface of the gear 44, and a vertical rod 46 is fixedly mounted on the outer side of the upper surface of the tooth plates 45. The upper end of 46 is fixedly connected to the corresponding clamping plate 42. When the mobile phone needs to be positioned, the servo motor 43 is turned on. The output end of the servo motor 43 drives the gear 44 to rotate. Since the outer surfaces of the gear 44 are symmetrically meshed with toothed plates 45, when the gear 44 rotates, it will drive the toothed plates 45 on both sides to make linear movements in opposite directions. The upright rod 46 fixed on the outer side of the upper surface of the toothed plate 45 moves with the toothed plate 45. The upper end of the upright rod 46 is fixedly connected to the corresponding clamping plate 42. Therefore, the upright rod 46 drives the clamping plate 42 to move, thereby realizing the operation of clamping or releasing the mobile phone placed on the carrier plate 41.

[0024] Specifically, a lead screw 21 is rotatably mounted inside the adjustment frame 2. A DC motor 22 is fixedly mounted on the upper surface of the adjustment frame 2. The output end of the DC motor 22 passes through the adjustment frame 2 and is fixedly connected to the lead screw 21. A lifting block 23 is threadedly mounted on the outer surface of the lead screw 21. A connecting plate 24 is fixedly mounted on one side of the lifting block 23. A lifting plate 25 is detachably connected to one side of the connecting plate 24. One side of the lower surface of the lifting plate 25 is fixedly connected to the coupling test plate 3. When it is necessary to adjust the height of the coupling test plate 3, the DC motor 22 is started. The output end of the DC motor 22 drives the lead screw 21 inside the adjustment frame 2 to rotate. The lifting block 23 is threadedly mounted on the outer surface of the lead screw 21. A connecting plate 24 is fixedly mounted on one side of the lifting block 23. A lifting plate 25 is detachably connected to one side of the connecting plate 24. One side of the lower surface of the lifting plate 25 is fixedly connected to the coupling test plate 3. Therefore, the up and down movement of the lifting block 23 will drive the coupling test plate 3 to rise and fall through the connecting plate 24 and the lifting plate 25, thereby adjusting the distance between the coupling test plate 3 and the mobile phone to test the coupling effect of the mobile phone at different distances.

[0025] Furthermore, a shielding protective sleeve 47 is fixedly connected between the bracket 4 and the carrier plate 41. The servo motor 43 is fixedly installed inside the shielding protective sleeve 47. The shielding protective sleeve 47 is made of a metal material with high magnetic permeability, which can effectively shield the electromagnetic interference generated by the servo motor 43 during operation.

[0026] Furthermore, the upper surface of the bracket 4 is symmetrically provided with sliding grooves 48, and the lower surface of the toothed plate 45 is fixedly connected with a sliding strip 49, and the sliding strip 49 is locked in the corresponding sliding groove 48. The sliding strip 49 fixedly connected to the lower surface of the toothed plate 45 is locked in the sliding grooves 48 symmetrically provided on the upper surface of the bracket 4, which ensures the stability of the movement of the toothed plate 45.

[0027] It is worth noting that the support 4 and the carrier plate 41 are connected by bolts with a support leg 410. The support leg 410 not only supports the carrier plate 41, but also enhances the stability of the entire structure. When the servo motor 43 drives the gear 44 to rotate, a certain amount of vibration and torque will be generated. The support leg 410 can disperse these forces and prevent relative displacement or deformation between the support 4 and the carrier plate 41.

[0028] It is worth noting that the upper surface of the carrier plate 41 is symmetrically provided with through slots 411, and the upright rod 46 is locked in the corresponding through slot 411. The upright rod 46 is locked in the through slots 411 symmetrically provided on the upper surface of the carrier plate 41, so the upright rod 46 drives the clamping plate 42 to move along the through slot 411.

[0029] It is worth mentioning that a limiting post 26 is fixedly provided inside the adjusting frame 2, and the limiting post 26 passes through the lifting block 23. The limiting post 26 restricts the rotation of the lifting block 23, so that when the lead screw 21 rotates, the lifting block 23 can only move up and down in a straight line along the lead screw 21.

[0030] It is worth emphasizing that one side of the connecting plate 24 is secured to the adjusting frame 2, and one side of the lifting plate 25 is secured to the connecting plate 24. The connecting plate 24 and the lifting plate 25 are connected by bolts. This connection method ensures the stability of the structure and has good maintainability. When the coupling test plate 3 needs to be replaced or repaired, the lifting plate 25 can be easily removed from the connecting plate 24 by simply unscrewing the bolts. The operation is simple and convenient.

[0031] Among them, the servo motor 43, DC motor 22, and coupling test board 3 are all existing technologies and will not be described in detail; at the same time, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail; the "front, back, left, and right" perspectives of this device are as follows: Figure 1 The direction shown in the diagram is the reference.

[0032] Working principle: When it is necessary to locate the mobile phone, the servo motor 43 is turned on. The output end of the servo motor 43 drives the gear 44 to rotate. Since the gear 44 has toothed plates 45 symmetrically meshed on both sides of its outer surface, when the gear 44 rotates, it will drive the toothed plates 45 on both sides to move in opposite directions or in a straight line. The upright rod 46 fixed on the outer side of the upper surface of the toothed plate 45 moves with the toothed plate 45. The upper end of the upright rod 46 is fixedly connected to the corresponding clamping plate 42, and the upright rod 46 is locked in the through groove 411 symmetrically opened on the upper surface of the carrier plate 41. Therefore, the upright rod 46 drives the clamping plate 42 to move along the through groove 411, thereby realizing the operation of clamping or releasing the mobile phone placed on the carrier plate 41. The slide bar 49 fixedly connected to the lower surface of the toothed plate 45 is locked in the slide groove 48 symmetrically opened on the upper surface of the bracket 4, ensuring the stability of the movement of the toothed plate 45.

[0033] When the height of the coupling test board 3 needs to be adjusted, the DC motor 22 is started. The output end of the DC motor 22 drives the lead screw 21 in the adjustment frame 2 to rotate. The outer surface of the lead screw 21 is threaded with a lifting block 23. A connecting plate 24 is fixedly installed on one side of the lifting block 23. A lifting plate 25 is detachably connected to one side of the connecting plate 24. The lower surface of the lifting plate 25 is fixedly connected to the coupling test board 3. Therefore, the up and down movement of the lifting block 23 will drive the coupling test board 3 to rise and fall through the connecting plate 24 and the lifting plate 25, thereby adjusting the distance between the coupling test board 3 and the mobile phone to test the coupling effect of the mobile phone at different distances.
