Technical Field
[0001] The utility model relates to the technical field of hearing aid testing, in particular to a Bluetooth hearing aid testing device. Background Art
[0002] A Bluetooth hearing aid is a small loudspeaker that uses Bluetooth transmission technology to amplify sounds that are originally inaudible, and then use the residual hearing of the hearing-impaired to send the sound to the auditory center of the brain, so that the sound can be felt, which brings great convenience to the hearing-impaired. It is mainly composed of five parts: microphone, amplifier, earphones, power supply and volume control. According to the conduction method, it can be divided into air conduction hearing aids and bone conduction hearing aids. After the Bluetooth hearing aid is produced and put into use, it should be tested to ensure that the produced Bluetooth hearing aids meet the corresponding requirements. At this time, a Bluetooth hearing aid testing device is needed.
[0003] According to the search, the Chinese patent website with patent number CN113473344A discloses a "testing device for hearing aid production". Through the arrangement of a first motor, a second motor, a screw rod, a moving block, a support plate, a conveying tray, a test tray and different test areas, the conveying tray is driven to rotate by the second motor to push the hearing aid to fall from the through hole on the support plate onto the test tray. Since there are different partitions on the test tray, the anti-fall performance of the hearing aid falling on different ground surfaces can be simulated. During the test, starting the first motor can adjust the height of the hearing aid test, thereby simulating the anti-fall performance of the hearing aid falling on patients of different heights. The anti-fall test of the hearing aid is relatively comprehensive. However, when the hearing aid is pushed to rotate with the rotation of the conveying tray, the bottom of the hearing aid will rub against the support plate, and according to the different positions of the placement holes of the hearing aid, the distance the hearing aid moves with the rotation of the conveying tray is different, resulting in different degrees of friction at the bottom of the hearing aid, and different effects on its appearance. The irrelevant variables of all the Bluetooth hearing aids participating in the test are not well controlled, thus affecting the accuracy of the test. Utility Model Content

DETAILED DESCRIPTION
[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0035] The following describes an embodiment of the utility model based on its overall structure. Embodiment 1:
[0036] A Bluetooth hearing aid test device, such as Figure 1-Figure 5 As shown, it includes a device body 1, a display screen 2 and a displacement mechanism 3.

The displacement mechanism 3 includes a screw motor 301, a slider 305 and a support plate 306. A screw 302 is arranged at the output end of the screw motor 301. A slide groove 303 is opened on the device body 1. A slide rail 304 is arranged in the slide groove 303. An intermittent parabolic mechanism 4 is arranged on the support plate 306. The intermittent parabolic mechanism 4 includes a first stepper motor 401, a rotating seat 402, an auxiliary plate 408 and an electromagnet 409. The rotating seat 4 02 is provided with a placement hole 403 and a groove 404, a movable plate 405 and a spring 407 are arranged in the groove 404, a block 406 is arranged on one side of the movable plate 405, and a magnetic seat 410 is arranged on one side of the electromagnet 409. The setting of the intermittent parabolic mechanism 4 makes the bottom of the Bluetooth hearing aid not directly contact the support plate 306, but abut against the movable plate 405. Therefore, when each Bluetooth hearing aid is thrown down, the degree of influence of the friction force is consistent, so that the irrelevant variable of the influence of the friction force is better controlled. The setting of the displacement mechanism 3 and the rotating disk 6 can be used to simulate users of different heights wearing Bluetooth hearing aids, and the influence of different ground materials on the anti-fall performance of the hearing aid, which increases the comprehensiveness of the test.

The tile test area 7, the wood board test area 8, the cement test area 9 and the asphalt test area 10 are distributed in a circle. When the second stepper motor 5 is started, it will drive the rotating disk 6 fixedly connected thereto, thereby realizing the replacement of different ground test areas during the rotation process. The fixed connection between the second stepper motor 5 and the rotating disk 6 ensures the stability of the rotating disk 6 during rotation. The setting of different test areas distributed in a circle enables the test device to quickly switch the test area, thereby improving the test efficiency.
[0038] See also Figure 1 , Figure 2 , Figure 3 The screw motor 301 is fixedly connected to the screw rod 302, the screw rod 302 is threadedly connected to the slider 305, the slider 305 is slidably connected to the slide rail 304, and two groups of sliders 305 and the slide rail 304 are provided. The two groups of sliders 305 and the slide rail 304 are symmetrically arranged. When the screw motor 301 is started, it drives the screw rod 302 fixedly connected to it to rotate, and with the assistance of the slide rail 304, the slider 305 moves up and down, and assists in adjusting the movable plate 405 to different test heights to simulate the anti-fall situation of users of different heights wearing Bluetooth hearing aids. The fixed connection between the screw motor 301 and the screw rod 302, as well as the design of threaded connection and sliding connection, ensure the accuracy and stability of the movement of the support plate 306, and the symmetrically arranged sliders 305 and slide rails 304 enhance the structural stability of the displacement mechanism.
[0039] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 The card block 406 is made of ferritic stainless steel, and a card slot 411 is provided on the magnetic base 410. The card block 406 is adapted to the card slot 411. The card block 406 is made of ferritic stainless steel and is adapted to the card slot 411 on the magnetic base 410, which provides good magnetic connection and positioning accuracy. At the same time, this material selection helps to improve the durability and corrosion resistance of the card block 406 and extend the service life of the equipment.
[0040] See also Figure 2 , Figure 3 , Figure 4There are multiple placement holes 403, and the multiple placement holes 403 are distributed in a circle. The number of movable plates 405 is consistent with the number of placement holes 403. The placement holes 403 are connected to the groove 404. Multiple Bluetooth hearing aids to be tested can be placed in the multiple circularly distributed placement holes 403 at one time, so that multiple hearing aids can be tested at the same time, which improves the test efficiency. The number of movable plates 405 and placement holes 403 is consistent, so that each Bluetooth hearing aid has a movable plate 405 for temporary auxiliary support underneath, and after the movable plate 405 is removed, the Bluetooth hearing aid can fall smoothly.
[0041] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 The first stepper motor 401 is fixedly connected to the rotating seat 402, the moving plate 405 is fixedly connected to the block 406, the block 406 is connected to the groove 404 through the spring 407, and the moving plate 405 is slidably connected to the groove 404 and the auxiliary plate 408. The first stepper motor 401 can be used to replace the Bluetooth hearing aid thrown down, and after the replacement is completed, the moving plate 405 and the block 406 are pulled out of the groove 404 by the magnetic attraction force of the electromagnet 409, so that the falling channel of the Bluetooth hearing aid can be opened smoothly. The use of the spring 407 provides a reset force for the moving plate 405, ensuring the reliability during the test.
[0042] See also Figure 4 The movable plate 405 has a U-shaped structure. The diameter of the arc-shaped part of the movable plate 405 is larger than the diameter of the placement hole 403.

The movable plate 405 made of polytetrafluoroethylene has an extremely low friction coefficient, ensuring that when the movable plate 405 is pulled away from the bottom of the Bluetooth hearing aid, the friction force has less impact on the Bluetooth hearing aid. Embodiment 2:
[0043] See also Figure 1 , Figure 2 A catheter 11 is provided on one side of the bottom of the support plate 306, and a first camera 12 and a second camera 13 are provided on the outer side of the catheter 11. The setting of the catheter 11 and the first camera 12 and the second camera 13 provides multi-angle image acquisition for the test and enhances the observation ability of the test, so that before the anti-fall test, the appearance of the Bluetooth hearing aid is first collected and displayed on the display screen 2 to make an initial record of the appearance of the Bluetooth hearing aid, so as to facilitate comparison with the situation after being thrown down.
[0044] See also Figure 1 , Figure 2 The placement hole 403 passes through the rotating seat 402, and the catheter 11 is connected to the placement hole 403. The catheter 11 is made of transparent material. The setting of the placement hole 403 and its connection with the catheter 11 enable the Bluetooth hearing aid to have its falling path opened smoothly after the movable plate 405 is pulled out of the groove 404, thereby ensuring the smooth progress of the anti-fall test. The catheter 11 is made of transparent material, which facilitates the first camera 12 and the second camera 13 to collect the appearance information of the Bluetooth hearing aid, thereby ensuring the clarity and accuracy of the image acquisition.
[0045] See also Figure 1 The lens of the first camera 12 is tilted upward, and the lens of the second camera 13 is tilted downward. When the Bluetooth hearing aid falls, the first camera 12 tilted upward captures images from an upward perspective, and the second camera 13 tilted downward captures images from a downward perspective, ensuring that the appearance images of the Bluetooth hearing aid at all angles are well captured. At the same time, the tilted settings of the first camera 12 and the second camera 13 provide upward and downward perspectives, which increases the three-dimensional sense and comprehensiveness of the test image.
[0046] The implementation principle of the utility model is as follows: first, the Bluetooth hearing aid to be tested is placed in the corresponding placement hole 403, the screw motor 301 is started to drive the screw 302 to rotate, and with the assistance of the slide rail 304 in the slide groove 303, the slider 305 drives the support plate 306 to move until it moves to the required height; then, the second stepper motor 5 is started to drive the rotating disk 6 to rotate until the center of the tile test area 7 is aligned with the center of the conduit 11; secondly, the first stepper motor 401 drives the rotating seat 402 After the rotation is completed, the electromagnet 409 is energized, and when the rotating seat 402 stops rotating, the magnetic attraction of the electromagnet 409 acts on the card block 406 through the magnetic seat 410, pulling the card block 406 and the movable plate 405 to move to the side of the card slot 411, and the movable plate 405 is pulled out of the groove 404, opening the upper and lower parts of the placement hole 403, so that the Bluetooth hearing aid in the placement hole 403 can fall smoothly. In this process, the spring 407 is stretched smoothly by the tension; when the movable plate 405 is moved When the Bluetooth hearing aid starts to fall, the first camera 12 and the second camera 13 are controlled to respectively capture the appearance images of the hearing aid, and the captured images are displayed through the display screen 2 for the test personnel to check the appearance of the fallen Bluetooth hearing aid, and the fallen Bluetooth hearing aid successfully falls on the tile test area 7, and the anti-fall performance test of this type of ground is carried out; again, the control process of the displacement mechanism 3 can be repeated to simulate the scene when users of different heights wear the Bluetooth hearing aid, and the anti-fall test is carried out on it, and the electromagnet 409 is powered off. Under the action of the elastic restoring force of the spring 407, the moving plate 405 and the card block 406 are smoothly reset, and the first stepper motor 401 is started again to drive the rotating seat 402 to rotate a certain angle, and the above-mentioned process of throwing the Bluetooth hearing aid down is repeated; finally, the second stepper motor 5 is repeated to drive the rotation of the rotating disk 6, and the test area is replaced with the wooden board test area 8, the cement test area 9 and the asphalt test area 10, and the anti-fall test of the Bluetooth hearing aid is repeated, and it is ensured that only one variable is changed in each test.
