[0030] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0031] As Figures 1 to 7 shown, this embodiment provides a test tooling for an automotive travel switch. The test tooling for the automotive travel switch includes a support frame 1, a clamping assembly 2, and a magnetic attraction impact assembly 3. Among them, the magnetic attraction impact assembly 3 includes a mounting frame 31, a magnetic attraction impact portion 32, and a drive control portion 33. The mounting frame 31 is arranged on the support frame 1, the magnetic attraction impact portion 32 is arranged on the mounting frame 31, and the drive control portion 33 is drivingly connected to the magnetic attraction impact portion 32. In the present utility model, the drive control portion 33 is drivingly connected to the magnetic attraction impact portion 32, so that the drive control portion 33 controls the operation of the magnetic attraction impact portion 32, so that the magnetic attraction impact portion 32 can impact the travel switch clamped by the clamping assembly 2, thereby achieving the purpose of performing a durability test on the travel switch. And the above control method adopts a circuit control method, and the on-off frequency of the magnetic attraction impact portion 32 can be controlled through the circuit control to achieve the test purpose of the impact frequency of the automotive travel switch. At the same time, the circuit control method is used to replace the expensive programmable power supply, and the cost price is relatively low, effectively solving the problem that the test tooling for the automotive travel switch in the prior art cannot be used in a low-temperature environment.

[0032] Specifically, as Figure 7 shown, the drive control portion 33 includes a controller 331, a relay 332, and a counter 333. The input end of the controller 331 is electrically connected to the input end of the relay 332, the output end of the relay 332 is electrically connected to the magnetic attraction impact portion 32, and the input end of the counter 333 is electrically connected to the controller 331, and the output end of the counter 333 is electrically connected to the travel switch. With such a setting, the controller 331 can control the on-off frequency of the working voltage of the magnetic attraction impact portion 32 through the connection of the relay 332, that is, the frequency of the up and down movement of the magnetic attraction impact portion 32. The magnetic attraction impact portion 32 impacts the automotive travel switch, causing the automotive travel switch to work or disconnect. At the same time, the counter 333 is set to be able to monitor the on-off times of the travel switch to achieve the purpose of testing the travel switch.

[0033] Furthermore, the drive control portion 33 further includes a supply power source 334. The controller 331, the relay 332, and the counter 333 are all electrically connected to the supply power source 334, so that the supply power source 334 can supply power to the controller 331, the relay 332, and the counter 333. Among them, the controller 331 is a programmable logic controller (PLC).

[0034] In this embodiment, the supply power source 334 is a DC power source, which can output a DC voltage of 0 - 60V and an output current of 0 - 10A. The model parameters of the relay 332 are: the operating voltage is 24V and the operating current is 10A. The connections between the controller 331, the relay 332, the counter 333 and the supply power source 334 in the drive control unit 33 are all made of high and low temperature resistant wires. Among them, the high and low temperature resistant wires can withstand working temperatures ranging from minus 40 degrees Celsius to 90 degrees Celsius.

[0035] It should be noted that the circuit control process is as follows: The DC power source outputs 24V of direct current. Since the working current of the magnetic attraction impact part 32 is relatively large, directly connecting it to the controller 331 will directly burn out the controller 331. Therefore, a relay 332 is added between the controller 331 and the DC power source. The controller 331 controls the coil end of the relay 332. The controller 331 is equivalent to a switch. One end of the controller 331 is connected to the positive pole of the DC power source, the other end of the controller 331 is connected to the coil (located) end of the relay 332, the other end of the relay 332 is connected to the negative pole of the DC power source, one end of the contact end of the relay 332 is connected to the positive pole of the DC power source, the other end of the contact end of the relay 332 is connected to the positive pole of the magnetic attraction impact part 32, and the negative pole of the magnetic attraction impact part 32 is connected to the negative pole of the DC power source. By programming, the controller 331 outputs the on-off frequency required in the automotive travel switch test. The positive pole of the counter 333 is connected to one end of the automotive travel switch, the other end of the automotive travel switch is connected to the DC power source, and the negative pole of the counter 333 is connected to the negative pole of the DC power source. The number displayed by the counter 333 is the on-off times of the automotive travel switch. If the automotive travel switch is damaged and always on or always off, the counter 333 will no longer count, and the displayed number will stay at the number when the automotive travel switch was working. The number displayed by the counter 333 serves to monitor the working condition of the automotive travel switch.

[0036] Specifically, the magnetic attraction impact part 32 includes a push-pull magnetic part 321 and an impact part 322. Among them, the impact part 322 is arranged with adjustable length to adapt to different travel switches, and at the same time, the versatility of the magnetic attraction impact part 32 is also improved. The iron core of the push-pull magnetic part 321 is connected to the impact part 322, and the drive control unit 33 is drivingly connected to the push-pull magnetic part 321. In this way, by driving the push-pull magnetic part 321 to expand and contract through the drive control unit 33, the impact part 322 can impact the travel switch clamped by the clamping assembly 2.

[0037] Among them, such as Figure 1 and Figure 2As shown in the figure, the impact member 322 includes an impact sleeve 3221, an adjustment rod 3222, and a locking member 3223. One end of the iron core of the push-pull magnetic attraction member 321 is connected to the impact sleeve 3221, and the adjustment rod 3222 extends into the other end of the impact sleeve 3221 and is slidably engaged with the inner wall of the impact sleeve 3221. In this way, the length of the adjustment rod 3222 extending into the impact sleeve 3221 can be adjusted to achieve the purpose of adjusting the length. At the same time, the locking member 3223 is sleeved on the adjustment rod 3222 to lock the adjustment rod 3222.

[0038] In this embodiment, the inner wall of the impact sleeve 3221 has internal threads, the outer wall of the adjustment rod 3222 has external threads, and the locking member 3223 is a locking nut. By the cooperation of the external threads and the internal threads, the purpose of adjusting the length of the adjustment rod 3222 extending out of the impact sleeve 3221 is achieved. Then, by the threaded engagement of the locking nut and the external threads, the adjustment rod 3222 can be locked.

[0039] Specifically, the clamping assembly 2 includes a clamping rod 21, a first clamping plate 22, a second clamping plate 23, and a clamping member 24. The first clamping plate 22 can be arranged on the support frame 1, the second clamping plate 23 and the first clamping plate 22 are sequentially sleeved on the clamping rod 21, and the area between the second clamping plate 23 and the first clamping plate 22 can accommodate a travel switch. Subsequently, the clamping member 24 is sleeved on the clamping rod 21 and is located on the side of the second clamping plate 23 away from the first clamping plate 22, so as to achieve the purpose of clamping the travel switch located between the second clamping plate 23 and the second clamping plate 23.

[0040] Further, as Figure 1 shown, the support frame 1 includes a first support plate 11, a second support plate 12, and a support column 13. Among them, the first support plate 11 is connected to the second support plate 12 through the support column 13. The first support plate 11 has an avoidance hole 111. A part of the clamping assembly 2 passes through the avoidance hole 111 and is connected to the first support plate 11. The mounting frame 31 is connected to the first support plate 11 and is arranged corresponding to the clamping assembly 2.

[0041] Optionally, the first clamping plate 22 includes a connecting circular plate 221 and a pressing circular plate 222 that are connected to each other. The diameter of the connecting circular plate 221 is larger than the diameter of the pressing circular plate 222. The connecting circular plate 221 is connected to the periphery of the avoidance hole 111, and the pressing circular plate 222 passes through the avoidance hole 111.

[0042] Specifically, the mounting frame 31 includes a mounting plate 311, a first connecting plate 312 and a second connecting plate 313 connected to both ends of the mounting plate 311. The magnetic attraction impact part 32 is arranged on the mounting plate 311, and both the first connecting plate 312 and the second connecting plate 313 are connected to the support frame 1. Among them, the shape of the mounting plate 311 is generally U-shaped.

[0043] In this embodiment, there are multiple clamping assemblies 2 and multiple magnetic attraction impact assemblies 3, and the multiple magnetic attraction impact assemblies 3 and the multiple clamping assemblies 2 are arranged in one-to-one correspondence. With this arrangement, multiple sets of travel switch tests can be carried out simultaneously, improving the test efficiency.

[0044] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here.
