Description

Technical Field

[0001] This utility model relates to the field of switch testing technology, specifically to a test device for counting the presses of automotive push-button switches. Background Technology

[0002] As a crucial component of automotive interiors, automotive push-button switches directly impact driver experience and driving safety. Therefore, the manufacturing process often involves testing parameters such as button feedback, contact stability, and lifespan through press counts. However, while conventional testing equipment for push-button switches can count the number of presses, it often lacks the ability to monitor and adjust the specific pressure applied during the pressing process. Consequently, the feedback effect of the switch under different pressure levels and press counts cannot be observed and adjusted in real time. Furthermore, for different types and specifications of push-button switches, excessive pressure can cause unnecessary damage and shorten lifespan, while insufficient pressure will negatively affect the test results. This highlights the limitations and functional simplification of such testing equipment. Utility Model Content

This test device can conveniently perform push-button switch press-counting tests while simultaneously adjusting the pressing force in real time according to the specific pressing depth of the button on the push-button switch, reducing unnecessary damage to the button. Furthermore, it can observe in real time the changes in pressing force caused by the feedback effect of the button on the push-button switch during the press-counting test, facilitating monitoring and adjustment, and further improving the testing effect of this test device.

[0004] The technical solution adopted by this utility model to solve the above problems is:

[0005] A test device for counting and pressing push buttons on a vehicle includes a base, a frame mounted on the base, and a test machine body consisting of multiple sets of pressing parts mounted on mounting seats and connecting seats slidably disposed at the upper and lower ends of the frame, and a clamping assembly for clamping and fixing the push buttons.

[0012] Compared with the prior art, this utility model has the following advantages and effects:

[0013] This utility model relates to a test device for counting and pressing automotive push-button switches. Compared to conventional push-button life testing machines, the overall structure of this test machine features a sliding connecting seat on the frame and a locking component rotatably mounted on the connecting seat. Combined with the upper drive component, this allows for the movement and corresponding distance of the mounting base and multiple pressing parts on it. This not only facilitates the clamping and fixing of push-button switches of different specifications and the adjustment of their pressing positions, but also allows for real-time display of the pressing pressure changes of the push-button switch by a pressure sensor connected to the bottom of the connecting rod within the pressing part.

Detailed Implementation

[0020] The present invention will now be described in detail with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0021] See Figure 1-2 This embodiment relates to a test device for counting the presses of a vehicle push button switch 110. The main body of the test device includes a base 100, a frame 101 mounted on it, and multiple sets of pressing parts 3 mounted on mounting seats 1 and connecting seats 2 that are slidably mounted at the upper and lower ends of the frame 101, and a clamping assembly 4 for clamping and fixing the push button switch 110. The multiple sets of pressing parts 3 are driven to slide up and down by a driving component 102 mounted on the top of the frame 101 and a connecting rod 103 that is hinged to the driving component 102 and the mounting seat 1 at both ends. The pressing part 3 includes a connecting rod 31 that acts on the mounting seat 1 and a pressing head 33 that is connected to the bottom of the connecting rod 31 through a pressure sensor 32. A locking member 20 is rotatably mounted on the seat body corresponding to the connection position between the connecting seat 2 and the frame 101.

[0022] Specifically in this embodiment, such as Figure 1In practical use, the overall structure of this testing machine allows the button switch 110 to be tested to be placed on the connecting seat 2 and clamped and fixed by the clamping component 4 provided on the connecting seat 2. The clamping component 4 can adopt a commonly used clamping structure found on testing machines for counting button switches 110 presses. After the button switch 110 is clamped and fixed on the connecting seat 2 by the clamping component 4, the position of the connecting seat 2 on the frame 101 can be adjusted and locked at the corresponding position by sliding the connecting seat 2 and rotating the locking component 20, which is a bolt-type structure on the connecting seat 2. During adjustment, the multiple sets of pressing parts 3 on the drive mounting base 1 can slide up and down according to the driving component 102, and the corresponding position adjustment and locking operation of the connecting seat 2 on the frame 101 can be determined in combination with the specific depth of the button on the button switch 110. The connecting rod 31 is hinged to the driving component 102 and the mounting base 1 respectively through pins 1031 with rotatable ends. The end of the connecting rod 31 connected to the driving component 102 is eccentrically connected to the corresponding drive shaft 1021 of the driving component 102, so that under the drive of the driving component 102, the connecting rod 31 is connected to the drive shaft. The eccentric rotation of 1021 drives the mounting base 1 and its multiple sets of pressing parts 3 to slide up and down along the frame 101. During the sliding process, the multiple sets of pressing parts 3 repeatedly press the corresponding button switch 110 on the lower connecting base 2, which is clamped and fixed by the clamping assembly 4. At the same time, during the pressing process, the test module set inside the base 100 and the operation panel 104 and display screen 105 connected to the test module on the base 100 display the corresponding number of presses and other working parameters in real time and adjust them accordingly. Specifically, the test module inside the base 100 and its... The upper operation panel 104 and display screen 105 can be adapted and set using the modular test element structure and corresponding connection method commonly used in conventional button life testing machines. In addition, under the drive of the drive component 102, the pressing part 3 on the mounting base 1 repeatedly presses the button switch 110 on the connecting base 2 through the pressing head 33 installed at the bottom of the connecting rod 31. The pressure sensor 32 installed at the bottom of the connecting rod 31 can be connected to the internal test module of the base 100, so that the pressure sensor 32 can display the real-time change of the pressing force during the pressing of the button switch 110.Compared to conventional button life testing machines, this type of testing machine features a sliding connecting seat 2 on its frame 101 and a locking element 20 rotatably mounted on the connecting seat 2. Combined with the upper drive component 102 driving the mounting base 1 and its multiple pressing parts 3, this design facilitates the clamping and fixing of button switches 110 of different specifications and the adjustment of their corresponding pressing positions. Furthermore, the pressing head 33, connected to the bottom of the connecting rod 31 via a pressure sensor 32, can display the real-time changes in the pressing force of the button on the button switch 110 during the pressing process. Simultaneously, during position adjustment, the connecting seat 2 can also adjust the pressing force by having the pressing head 33 abut against the button and being driven by the drive component 102 to sequentially press the button. The maximum and minimum pressures displayed by the pressure sensor 32 are set to a threshold, thereby ensuring that the corresponding button on the push-button switch 110 has the optimal pressing force and depth during the pressing process. The real-time feedback effect of the button on the push-button switch 110 can be judged based on the pressure changes on the pressure sensor 32. Furthermore, abnormal situations such as non-rebound of the button on the push-button switch 110 can be dealt with in a timely manner based on the pressure changes. This not only effectively reduces unnecessary damage to the button due to the special structure of the automotive push-button switch 110, but also ensures the uniformity of the pressing force of multiple pressing parts 3 during the pressing process and the adaptability of the corresponding structural settings and feedback effects of the button on the push-button switch 110. This effectively improves the testing effect and applicability, and meets different usage requirements.

[0023] The connecting rod 31 is connected to the driving component 102 via a connecting part 106 provided at a corresponding position on the frame 101. The connecting part 106 includes a bushing 1061 rotatably mounted on the top of the frame 101 and a second connecting seat 1062 mounted on the bushing 1061 via a second locking member 1063 and eccentrically connected to the driving component 102 and adjustable. One end of the connecting rod 103 is hinged to the second connecting seat 1062. (See reference for details.) Figure 3As shown, when the drive component 102 is working, it drives the drive shaft 1021 to rotate within the corresponding bushing 1061 on the frame 101. Simultaneously, the second connecting seat 1062, which is eccentrically connected to the drive shaft 1021 of the drive component 102 via the second locking member 1063, rotates eccentrically. At the same time, the hinged connecting rod 31 drives the lower mounting seat 1 to slide up and down along the frame 101. In actual use, the specific pressing depth of the button on the push-button switch 110 can be determined by the matching grooves provided at corresponding positions on the second locking member 1063 and the second connecting seat 1062, which are designed with bolt-like structures. The body 10621 can realize the position adjustment and corresponding locking process of the second connecting seat 1062 on the drive shaft 1021 of the drive component 102, thereby appropriately adjusting the eccentricity of the second connecting seat 1062 on the drive shaft 1021 of the drive component 102, and accordingly changing the corresponding sliding distance of the mounting seat 1 connected by the connecting rod 31 on the frame 101. Combined with the position adjustment process of the connecting seat 2, the pressing heads 33 in the multiple pressing parts 3 on the mounting seat 1 can perform a continuous pressing process at a corresponding depth relative to the specific pressing structure on the button switch 110, further improving the adjustability and flexibility of this testing machine body.

[0024] like Figure 3 As shown, a first locking ring 311 and a second locking ring 312 are rotatably mounted on the corresponding rods at the upper and lower ends of the connecting rod 31. The pressing part 3 is detachably mounted on the mounting base 1 via the second locking ring 312 on the connecting rod 31. Multiple sets of weights 313 of different weights are sleeved on the corresponding rods between the first locking rings 311 on the connecting rod 31, which are located above the mounting base 1. A compression spring 314 is also sleeved on the corresponding rods between the second locking rings 312 on the connecting rod 31, which are located below the mounting base 1. Specifically, the first locking rings 311 and the second locking rings 312 are bolted together and rotated through the threaded adapter rods at the upper and lower ends of the connecting rod 31. The second locking ring 312 allows for the detachable connection of the connecting rod 31 to the mounting base 1. (See installation instructions.) Figure 1As shown, by rotating the second locking ring 312 at the lower end of the connecting rod 31 in conjunction with the elastic force of the compression spring 314, the pressing force of the pressing head 33 connected to the bottom of the connecting rod 31 via the pressure sensor 32 can be appropriately changed while ensuring the stability of the connecting rod 31 in its fixed position on the mounting base 1. Furthermore, according to usage requirements, the weight of the connecting rod 31 can be adjusted by using multiple sets of weights 313 with different weights fitted on the upper end of the connecting rod 31 and the first locking ring 311. Combined with the action of the second locking ring 312 at the lower end of the connecting rod 31 and the compression spring 314 that abuts against the mounting base 1, the initial pressing force can be adjusted. This is then combined with the subsequent connection of the connecting base 2 and the connecting part 1. The second connecting seat 1062 in section 06 is adjusted in position, and the pressure of the pressing head 33 is displayed by the pressure sensor 32 during the pressing process, so as to adjust the optimal pressing force and pressing depth. The pressing part 3 with this structure can further improve the structural detachability, functional diversity and usage flexibility of the pressing part 3, and further improve its adjustable range of pressing force, so as to facilitate installation, disassembly and replacement. Combined with the addition and connection of the pressure spring 314 on the corresponding rod, it can play a certain buffering effect during the pressing of the pressing head 33, so as to ensure the pressing stability of the pressing part 3 and further reduce the unnecessary damage to the button switch 110, thus meeting different usage needs.

[0025] The pressure sensor 32 is detachably mounted on the corresponding rod body at the bottom of the connecting rod 31 via a detachable structure. The pressing head 33 is detachably mounted on the pressure sensor 32 via a detachable structure. A pressing end 331 can also be detachably mounted on the bottom of the pressing head 33. (See details...) Figure 4 As shown, the pressure sensor 32 is detachably connected to the bottom of the connecting rod 31 via bolts that are rotatably mounted in a matching threaded hole 315 on the corresponding rod body. The pressing head 33 is detachably mounted on the detection end of the pressure sensor 32 via multiple sets of bolts. This facilitates the installation, removal, replacement, and cleaning of the pressure sensor 32 and the pressing head 33 on the connecting rod 31, improving ease of use. In addition, the pressing head 33 is rotatably provided with a pressing end 331 via a threaded connection structure. The pressing end 331 can be configured as a capsule-shaped structure or a rubber pad structure according to usage requirements, thereby further improving the cushioning effect on the button during pressing and reducing unnecessary damage to the button switch 110. Furthermore, the detachable connection of the pressing end 331 also facilitates replacement and adjustment.

[0026] from Figure 1 , Figure 4 as well as Figure 5As can be seen, the clamping assembly 4 includes a first clamping member 41 and a second clamping member 42. The first clamping member 41 includes a plurality of first clamping blocks 411 with a plurality of first sliding grooves 21 arranged in a crisscross pattern along the top surface of the connecting seat 2, which slide towards each other and have slots 412. The second clamping member 42 includes two sets of fixing plates 421 that are slidably disposed relative to each other along the second sliding grooves 22 on both sides of the connecting seat 2, and two sets of clamping plates 423 that are slidably disposed towards each other along both ends of the connecting seat 2 on the two sets of fixing plates 421 via adjusting members 422. A third locking member 4211 is also rotatably disposed on the fixing plate 421 at the sliding position with the connecting seat 2. Figure 4 As shown, the first clamping member 41 can be installed, disassembled, and slid through multiple sets of first clamping blocks 411 arranged along several sets of first sliding grooves 21 on the top surface of the connecting seat 2. Combined with the corresponding slots 412, it enables the clamping, fixing, and removal of the button switch 110 with an adaptive structure. Figure 5 As shown, the second clamping member 42 can be installed, disassembled, and its position adjusted during sliding by the second sliding groove 22 provided on the corresponding positions of the two sets of fixing plates 421 along the two sides of the connecting seat 2. It is locked in the corresponding position by the third locking member 4211 which is rotatably set with a bolt structure. Then, by rotating the adjusting member 422 on the fixing plate 421, the two sets of clamping plates 423 on the two sets of fixing plates 421 can slide towards each other and clamp and fix the corresponding button switch 110 and remove it. Specifically, the first clamping member 41 and the second clamping member 42 can be selected according to the different specifications of the button switch 110, thereby further improving the adjustable range, clamping stability and usage flexibility of this clamping component 4, meeting different clamping needs, and improving the applicability of this testing machine body for pressing and counting tests of automotive button switches 110.

[0027] An anti-slip pad 4231 is also attached to the corresponding clamping surface of the clamping plate 423. The additional structure of the anti-slip pad 4231 can provide a certain buffering, shock absorption and anti-slip protection effect on the surface of the button switch 110 during the clamping process of the second clamping member 42 through the corresponding clamping surface of the clamping plate 423, thereby improving the stability of the vehicle button switch 110 during the press counting test through the pressing part 3.

[0028] The pressing part 3 is slidably mounted on the mounting base 1 via a through groove 11 provided at a corresponding position on the mounting base 1. The through groove 11 is H-shaped. For details, please refer to [link / reference needed]. Figure 6As shown, the pressing part 3, which slides on the mounting base 1 via the through groove 11, can be easily adjusted in position. Combined with the "H"-shaped through groove 11 structure, the flexibility of adjusting the position of the pressing part 3 on the corresponding through groove 11 of the mounting base 1 can be further improved. This allows for the simultaneous pressing test of multiple automotive button switches 110 on the steering wheel or center console via the position adjustment of the pressing part 3 on the corresponding through groove 11 of the mounting base 1. In addition, the through groove 11 structure can also be arranged in multiple "H"-shaped parallel arrangements according to usage requirements, thereby realizing the corresponding position adjustment process of multiple sets of pressing parts 3 on multiple rows to meet different testing needs.
