[0018] Beneficial effects of the present invention:

[0019] 1. After the helmet body presses the supporting piece, the supporting piece drives the trapezoidal block to move downward. When the trapezoidal block moves downward, the inclined surfaces on both sides of the trapezoidal block squeeze the rotating plates on both sides. At this time, the rotating plates on both sides flip along the round rod in the middle. When the rotating plate flips, the push-pull plate pushes the T-shaped rod. At this time, the T-shaped rods on both sides drive the clamping plates to approach each other, thereby clamping and fixing the lower edge of the helmet body. Since the helmet body is placed on the supporting piece and the supporting piece is pressed by gravity, the clamping plates will not loosen, so as to ensure the stability of the helmet body when testing the performance of the helmet Bluetooth headset. The sliding adjustment rod makes it slide to the right in the adjustment groove. At this time, the adjusting rod drives the T-shaped rod to move synchronously, and the T-shaped rod drives the clamping plate to cancel the clamping of the helmet body when moving. At this time, the rotating plates on both sides flip away from each other, and at this time, the lower part of the rotating plate pushes the trapezoidal block upward, thereby causing the supporting piece to drive the helmet body to push out upward.

[0020] 2. The present invention turns on the electric push rod to rise, and the center piece moves upward. When the center piece moves upward, it drives the folding plate to flip on the L-shaped block. At this time, the folding plate drives the synchronous plate to rotate on the L-shaped block through the moving frame. At this time, the moving frame is driven by the synchronous plate and the folding plate to move in the horizontal direction. At this time, multiple moving frames drive the rubber blocks to move away from each other and then fix the inner wall of the helmet body in a circumferential manner. The lower part of the helmet body is clamped and fixed by cooperating with multiple supporting boxes to achieve multiple fixations of the helmet body, thereby effectively avoiding the loosening and falling off of the helmet body due to bumps and vibrations during the performance test of the helmet Bluetooth headset, thereby affecting the accuracy of the performance test of the helmet Bluetooth headset.

[0021] 3. The present invention drives the threaded rod to rotate by opening the electric slider so that the helmet Bluetooth headset on the contact plate moves forward and backward along the threaded rod, thereby simulating the influence of wind on it when driving on the road. At the same time, controlling the number of revolutions of the electric slider can control the movement speed of the contact plate so that different wind speeds are generated when it moves. By selecting different arc plates to move up, different degrees of bumps of the simulated road surface can be made when the contact plate moves. At this time, turning on the audio analyzer to simulate whether the performance of the helmet Bluetooth headset is normal under the influence of different bumps and different wind speeds in actual use.

[0022] 4. The present invention opens the earphone body to put it in use, and then turns on the audio analyzer. At this time, the electric slider opens to allow the installation box to drive the audio analyzer to move in a circular direction on the inner side of the ring. When collecting the audio data of the earphone body, the circular movement also satisfies the collection and analysis of the audio in the earphone body from different directions, so as to ensure that the audio data of the earphone body is collected more accurately and comprehensively.

[0023] 5. The present invention turns on the electric slider to drive the gear ring to rotate, and when the gear ring rotates, it synchronously drives multiple driving wheels to rotate. When the multiple driving wheels rotate, they synchronously drive the movable plates meshing with them to move along the axis of the outer ring, thereby making the multiple movable plates move away from each other or away from each other, thereby meeting the need to place helmets of different sizes, thereby ensuring the stability of the helmet during the Bluetooth headset performance test.

[0038] A performance testing device for a helmet Bluetooth headset is used to test whether the audio data of the Bluetooth headset is normal during use. The helmet Bluetooth headset is a kind of high-fidelity ultra-thin audio product. The audio analyzer (model: TES TB1673-TES-1358C) used for testing the audio of the helmet Bluetooth headset belongs to an intelligent sensing system.

[0039] like Figure 1-Figure 10 As shown, the helmet Bluetooth headset comprises a helmet body 1, and mounting grooves 10 are provided on both sides of the helmet body 1. Buttons 11 installed on the helmet body 1 are provided on the upper and lower sides of the mounting groove 10. An earphone body 12 is provided in the mounting groove 10. It is characterized in that the performance testing device comprises a contact plate 2;

[0040] Telescopic rods 20 placed on the ground are provided at the four corners of the contact plate 2, a connecting seat 21 is fixedly installed on the top of the telescopic rod 20, two groups of connecting seats 21 are provided, and a threaded rod 22 is slidably installed between each group of connecting seats 21 through an electric slider, the threaded rod 22 penetrates and is threadedly rotated in the contact plate 2, an adjusting unit 3 is fixedly installed on the upper end surface of the contact plate 2, an internal fixing unit 4 fixedly connected to the contact plate 2 is provided in the middle of the adjusting unit 3, a test unit 5 fixed to the contact plate 2 is provided outside the adjusting unit 3, and a simulation unit 6 is provided below the contact plate 2.

[0041] The mounting groove 10 is used to mount the earphone body 12 on the helmet body 1, so as to facilitate the normal use of the earphone body 12 when wearing a helmet. By arranging the mounting grooves 10 on both sides of the helmet body 1, the user can install the earphone body 12 in the mounting grooves 10 as needed according to the usage habits. By pressing the button 11, the fixation and disassembly between the earphone body 12 and the helmet body 1 are facilitated. The setting of the adjustment unit 3 facilitates the placement and fixation of helmet bodies 1 of different specifications. The internal fixing unit 4 facilitates the internal fixation of the placed helmet body 1. The double internal and external fixation prevents the helmet body 1 from loosening and falling under the simulation of different road surfaces and speeds, thereby affecting the audio test of the earphone body 12 in the helmet body 1.

[0042] The adjustment unit 3 includes an outer ring 31, an inner ring 32 fixedly connected to the contact plate 2 is provided in the middle of the outer ring 31, grooves are circumferentially provided on the upper end faces of the inner ring 32 and the outer ring 31, a gear ring 33 is rotatably installed on the inner side of the outer ring 31 through an electric slider, a plurality of equally spaced driving wheels 34 are provided on the side of the gear ring 33 away from the outer ring 31, the driving wheel 34 is meshed with the lower part of the gear ring 33, the driving wheel 34 is rotatably connected to the contact plate 2, a movable plate 35 is slidably installed in the grooves on the inner ring 32 and the outer ring 31, and teeth arranged on one side of the movable plate 35 are meshed with the upper part of the driving wheel 34.

[0043] When placing helmet bodies 1 of different specifications, turn on the electric slider to drive the ring gear 33 to rotate. When the ring gear 33 rotates, it synchronously drives the multiple driving wheels 34 to rotate. When the multiple driving wheels 34 rotate, they synchronously drive the movable plates 35 meshing therewith to move along the axis of the outer ring 31, thereby making the multiple movable plates 35 move away from each other or away from each other, thereby meeting the need to place helmet bodies 1 of different specifications and sizes, thereby ensuring the stability of the helmet Bluetooth headset during performance testing.

[0044] A support frame 36 is fixedly installed on the upper end surface of the movable plate 35, and a supporting box 37 is fixedly installed on the upper end surface of the support frame 36. Side blocks 371 are symmetrically installed on both sides of the middle of the supporting box 37, and a supporting piece 372 is slidably installed between the two side blocks 371. A spring connected to the supporting piece 372 is provided in the middle of the side block 371, and a trapezoidal block 373 is fixedly installed on the lower end surface of the supporting piece 372. Round rods 374 are fixedly installed on both sides of the inner cavity of the supporting box 37, and a rotating plate 375 is rotatably installed on the round rod 374. The rotating plates 375 on both sides are symmetrically arranged and a spring connected to the supporting box 37 is provided on the side away from the two rotating plates 375. The lower part of the rotating plate 375 is arranged with an inclined surface and fits with the inclined surface of the trapezoidal block 373.

[0045] A T-shaped rod 376 is provided above the side block 371 and passes through and slides in the supporting box 37. A clamping plate 377 is fixedly installed on the adjacent side of the two T-shaped rods 376. A push-pull plate 378 is fixedly installed on one side of the upper part of the rotating plate 375. The push-pull plate 378 is located at one end of the T-shaped rod 376 to limit it. An adjusting groove 379 is provided on one side of the supporting box 37. An adjusting rod 3790 fixedly connected to one end of the T-shaped rod 376 is provided in the adjusting groove 379. A fixed block 3791 fixedly connected to the supporting box 37 is provided on the upper part of the adjusting groove 379. A limiting plate 3792 with a U-shaped side is slidably installed in the middle of the fixed block 3791.

[0046] When the helmet body 1 is fixed before the performance test of the helmet Bluetooth headset, the lower edge of the helmet body 1 is aligned with the multiple supporting boxes 37 and then lowered. After the helmet body 1 presses the supporting piece 372, the supporting piece 372 drives the trapezoidal block 373 to move downward. When the trapezoidal block 373 moves downward, the inclined surfaces on both sides of the trapezoidal block 373 squeeze the rotating plates 375 on both sides. At this time, the rotating plates 375 on both sides are flipped along the round rod 374 in the middle. When the rotating plate 375 flips, the T-shaped rod 376 is pushed by the push-pull plate 378. At this time, the T-shaped rod 376 on both sides drives the clamping plates 377 to approach each other, so as to clamp and fix the lower edge of the helmet body 1. Since the helmet body 1 is placed on the supporting piece 372 and the supporting piece 372 is pressed by gravity, the clamping plate 377 will not loosen. In order to ensure the stability of the helmet body 1 during the performance test of the helmet Bluetooth headset, when the helmet body 1 is taken out after the performance test of the helmet Bluetooth headset is completed, the limit plate 3792 is pulled upward to cancel the restriction on the adjustment rod 3790, and then the adjustment rod 3790 is slid to slide to the right in the adjustment slot 379. At this time, the adjustment rod 3790 drives the T-bar 376 to move synchronously, and the T-bar 376 drives the clamping plate 377 to cancel the clamping of the helmet body 1 when it moves. At this time, the rotating plates 375 on both sides are flipped away from each other. At this time, the lower part of the rotating plate 375 pushes the trapezoidal block 373 upward, and then the supporting piece 372 drives the helmet body 1 to be pushed upward. Compared with the existing device, the present invention can cancel the clamping of the helmet body 1 while also pushing the helmet body 1 upward.

[0047] The internal fixing unit 4 includes a support column 41, a placement frame 42 is fixedly installed on the top of the support column 41, an electric push rod 43 is fixedly installed in the middle of the placement frame 42, the telescopic end of the electric push rod 43 passes through and slides in the placement frame 42, an L-shaped block 44 is annularly fixedly installed on the upper end surface of the placement frame 42, and a center piece 45 is fixedly installed on the upper end surface of the electric push rod 43.

[0048] A folding plate 46 is rotatably installed between the center piece 45 and multiple L-shaped blocks 44. A synchronous plate 47 rotatably connected to the L-shaped block 44 is provided on the side of the folding plate 46 away from the center piece 45. A movable frame 48 is rotatably installed together with the synchronous plate 47 and the side of the folding plate 46 away from the L-shaped block 44, and a rubber block 49 is fixedly installed on one end of the movable frame 48.

[0049] When the helmet body 1 is internally fixed, the electric push rod 43 is turned on and rises. At this time, the center piece 45 moves up. When the center piece 45 moves up, it drives the folding plate 46 to flip on the L-shaped block 44. At this time, the folding plate 46 drives the synchronous plate 47 to rotate on the L-shaped block 44 through the moving frame 48. At this time, the moving frame 48 is moved in the horizontal direction under the drive of the synchronous plate 47 and the folding plate 46. At this time, the multiple moving frames 48 drive the rubber blocks 49 to move away from each other, thereby annularly abutting and fixing the inner wall of the helmet body 1. By cooperating with multiple supporting boxes 37 to clamp and fix the lower part of the helmet body 1, multiple fixations of the helmet body 1 are achieved, thereby effectively avoiding the loosening and falling off of the helmet body 1 due to bumps and vibrations during the performance test of the helmet Bluetooth headset, thereby affecting the accuracy of the performance test of the helmet Bluetooth headset.

[0050] The test unit 5 includes vertical plates 51 symmetrically installed on both sides above the contact plate 2. A circular ring 52 is fixedly installed on the upper end surfaces of the two vertical plates 51. A T-shaped groove 53 is circumferentially opened on the inner side of the circular ring 52. An installation box 54 is slidably installed in the T-shaped groove 53 through an electric slider. An audio analyzer 55 is detachably installed in the installation box 54.

[0051] When testing the audio during the performance test of the helmet Bluetooth headset, the headset body 12 is opened to put it in use, and then the audio analyzer 55 is turned on. At this time, the electric slider is opened to allow the installation box 54 to drive the audio analyzer 55 to move in a circumferential direction on the inner side of the ring 52. When collecting the audio data of the headset body 12, the circumferential movement also satisfies the collection and analysis of the audio in the headset body 12 from different directions, so as to ensure that the audio data of the headset body 12 is collected more accurately and comprehensively.

[0052] The simulation unit 6 includes a rectangular box 61, and a plurality of groups of placement grooves 62 are arranged at equal intervals on the upper end surface of the rectangular box 61. The placement grooves 62, and the front side of the rectangular box 61 are provided with through grooves that correspond to the plurality of groups of placement grooves 62 and pass through the through grooves at equal intervals. An arc plate 63 is slidably installed in the placement groove 62, and an adjustment block 64 that passes through the through groove is fixedly installed on one side of the arc plate 63 close to the through groove.

[0053] A transversely arranged concave plate 65 is fixedly installed at the front part of the front side of the rectangular box 61, a concave member 66 is slidably installed in the concave plate 65, a cylinder 67 is fixedly installed on the upper end surface of the concave member 66, and a support plate for supporting the adjustment block 64 is fixedly installed at the telescopic end of the cylinder 67.

[0054] Since the use of helmet Bluetooth headsets when riding on the road will be affected by wind speed and bumps, in order to ensure the authenticity of the performance test of the helmet Bluetooth headset, the electric slider is turned on to drive the threaded rod 22 to rotate so that the helmet Bluetooth headset on the contact plate 2 moves back and forth along the threaded rod 22, thereby simulating the impact of wind on it when driving on the road. At the same time, controlling the number of revolutions of the electric slider can control the movement speed of the contact plate 2 so that different wind speeds are generated when it moves. By selecting different arc plates 63 to move up, different degrees of bumps on the simulated road surface can be achieved when the contact plate 2 moves. At this time, the audio analyzer 55 is turned on to simulate whether the performance of the helmet Bluetooth headset is normal under the influence of different bumps and different wind speeds in actual use. Compared with the existing device, the present invention can simulate the performance of the helmet Bluetooth headset in different usage environments.

[0055] The arc plate 63 is arranged in an arc-shaped corrugation, and the arc plate 63 is arranged to simulate the bumps of the actual road surface. When the contact plate 2 moves, it always contacts with one of the arc plates 63 .

[0056] When the present invention is in use, when placing helmet bodies 1 of different specifications, the electric slider is turned on to drive the gear ring 33 to rotate. When the gear ring 33 rotates, it simultaneously drives multiple driving wheels 34 to rotate. When the multiple driving wheels 34 rotate, they simultaneously drive the movable plates 35 meshing therewith to move along the axis of the outer ring 31, thereby making the multiple movable plates 35 move away from each other or away from each other, thereby satisfying the placement of helmet bodies 1 of different specifications and sizes, thereby ensuring the stability of the helmet Bluetooth headset performance test, and lowering the lower edge of the helmet body 1 after it corresponds to the multiple supporting boxes 37. After that, after the helmet body 1 presses the supporting piece 372, the supporting piece 372 drives the trapezoidal block 373 to move downward. When the trapezoidal block 373 moves downward, the inclined surfaces on both sides of the trapezoidal block 373 squeeze the rotating plates 375 on both sides. At this time, the rotating plates 375 on both sides flip along the round rod 374 in the middle. When the rotating plate 375 flips, the T-shaped rod is pushed by the push-pull plate 378 376, at this time, the T-shaped rods 376 on both sides drive the clamping plates 377 to approach each other so as to clamp and fix the lower edge of the helmet body 1. Since the helmet body 1 is placed on the supporting member 372 and the supporting member 372 is pressed by gravity, the clamping plates 377 will not be loosened, so as to ensure the stability of the helmet body 1 during the performance test of the helmet Bluetooth headset. When the helmet body 1 is taken out after the performance test of the helmet Bluetooth headset is completed, the limit plate 3792 is pulled upward to cancel the restriction on the adjustment rod 3790, and then the adjustment rod 3790 is slid to slide to the right in the adjustment slot 379. At this time, the adjustment rod 3790 drives the T-shaped rod 376 to move synchronously. When the T-shaped rod 376 moves, it drives the clamping plates 377 to cancel the clamping of the helmet body 1. At this time, the rotating plates 375 on both sides are flipped away from each other. At this time, the lower part of the rotating plate 375 pushes the trapezoidal block 373 upward, so that the supporting member 372 drives the helmet body 1 to be pushed upward;

[0057] When the helmet body 1 is internally fixed, the electric push rod 43 is turned on to rise, and the center piece 45 moves up. When the center piece 45 moves up, it drives the folding plate 46 to flip on the L-shaped block 44. At this time, the folding plate 46 drives the synchronous plate 47 to rotate on the L-shaped block 44 through the moving frame 48. At this time, the moving frame 48 is moved in the horizontal direction under the drive of the synchronous plate 47 and the folding plate 46. At this time, the multiple moving frames 48 drive the rubber blocks 49 to move away from each other, thereby performing annular resistance and fixation on the inner wall of the helmet body 1. By cooperating with multiple supporting boxes 37 to clamp and fix the lower part of the helmet body 1, multiple fixations of the helmet body 1 are achieved, thereby effectively avoiding the loosening and falling off of the helmet body 1 due to bumps and vibrations during the performance test of the helmet Bluetooth headset, thereby affecting the accuracy of the performance test of the helmet Bluetooth headset;

[0058] In order to ensure the authenticity of the performance test of the helmet Bluetooth headset, the electric slider is turned on to drive the threaded rod 22 to rotate so that the helmet Bluetooth headset on the contact plate 2 moves forward and backward along the threaded rod 22, thereby simulating the influence of wind force on it when driving on the road. At the same time, controlling the number of revolutions of the electric slider can control the moving speed of the contact plate 2 so that different wind speeds are generated when it moves. By selecting different arc plates 63 to move up, the contact plate 2 simulates different degrees of bumps on the road when it moves. At this time, the audio analyzer 55 is turned on to simulate whether the performance of the helmet Bluetooth headset is normal under the influence of different bumps and different wind speeds in actual use.

[0059] When testing the audio during the performance test of the helmet Bluetooth headset, the headset body 12 is opened to put it in use, and then the audio analyzer 55 is turned on. At this time, the electric slider is opened to allow the installation box 54 to drive the audio analyzer 55 to move in a circumferential direction on the inner side of the ring 52. When collecting the audio data of the headset body 12, the circumferential movement also satisfies the collection and analysis of the audio in the headset body 12 from different directions, so as to ensure that the audio data of the headset body 12 is collected more accurately and comprehensively.
