The specific structure of the testing device of the locking assembly according to the embodiment of the present invention will be described with reference to fig. 1 and 2.
As shown in fig. 1 and 2, fig. 1 discloses a testing device of a locking assembly, which comprises a mounting table 1, a load output mechanism 2, a connecting mechanism 3 and a signal transmission mechanism 4. The mounting table 1 is used for mounting the locking assembly 6. The load output mechanism 2 is provided on the mount table 1. One end of the connecting mechanism 3 is detachably connected with the output end of the load output mechanism 2, the load output mechanism 2 can adjust the load applied to the connecting mechanism 3, and the other end of the connecting mechanism 3 is detachably connected with the locking assembly 6. The signal transmission mechanism 4 is arranged on the mounting table 1, and the transmission end of the signal transmission mechanism 4 is detachably matched with the connector of the locking assembly 6.
It can be understood that the output end of the load output mechanism 2 can be connected with the locking assembly 6 through the connecting mechanism 3, so that a load torque capable of simulating the running condition of the whole vehicle is provided for the locking assembly 6, the locking assembly 6 can perform gear switching under the environment simulating the running condition of the whole vehicle, and the reliability of the test result of the locking assembly 6 is improved. And load output mechanism 2 can also adjust its load of applying through coupling mechanism 3 to locking assembly 6, is favorable to testing locking assembly 6 under multiple operating condition, further improves the reliability of locking assembly 6's capability test result. The transmission end of the signal transmission mechanism can be matched with the connector of the locking assembly 6, so that the signal can be conveniently input into the locking assembly 6, the locking assembly 6 can complete various different function tests, the application range of the testing device is improved, meanwhile, the signal transmission mechanism can also transmit the operation parameters of the locking assembly 6 in the testing process to a lower computer, the user can acquire the performance of the locking assembly 6 according to the parameter change in the operation process, the intuitive acquisition of the related performance of the locking assembly 6 by the user is facilitated, and the use experience of the user is improved.
According to the testing arrangement of locking assembly of this embodiment, load output mechanism 2, coupling mechanism 3 and signal transmission mechanism 4 all set up on mount table 1, make whole device have little volume, high integration, light weight and low-cost characteristics, be convenient for transport, be applicable to the application of multiple occasion, simultaneously because the device volume is less, can lay in multiple environmental equipment, thereby can test locking assembly 6 under multiple environment such as low temperature, normal atmospheric temperature and high temperature, locking assembly 6's test range has been improved greatly.
In some embodiments, as shown in fig. 1 and 2, the load output mechanism 2 includes a power source 21 and a loading assembly 22. The power source 21 is provided on the mount table 1. The loading assembly 22 is connected with the output end of the power source 21, the loading assembly 22 can clamp the connecting mechanism 3, and the power source 21 can adjust the power output by the loading assembly 22 so as to adjust the load applied by the loading assembly 22 to the connecting mechanism 3.
It can be understood that, by adjusting the power output by the power source 21, the load applied by the loading component 22 to the connecting mechanism 3 can be conveniently adjusted, and then the test environment of the locking assembly 6 can be adjusted, so that the test range of the locking assembly 6 is improved.
In some embodiments, as shown in fig. 1 and 2, the loading assembly 22 includes a pneumatic brake having a friction disc removably coupled to the coupling mechanism 3.
It can be understood that when the air pressure inside the pneumatic brake is changed, the friction force between the friction disc of the pneumatic brake and the connecting mechanism 3 is also changed relatively, and when the air pressure inside the pneumatic brake is constant, the output friction force is also fixed, so that the locking assembly 6 can be conveniently provided with stable torque load through the connecting mechanism 3. When the friction disc of the pneumatic brake clamps the connecting mechanism 3, the friction limiting effect is achieved on the rotation of the connecting mechanism 3, and the locking assembly 6 drives the connecting mechanism 3 to rotate in working processes of gear switching and the like. When the friction discs of the pneumatic brake exert different clamping forces on the connecting mechanism 3, namely, the friction discs exert different torque loads on the locking assembly 6, so that gear shifting of the locking assembly 6 under the running environment of the whole vehicle can be conveniently simulated. It should be noted that, in the process of switching between different gears, the locking assembly 6 can drive the connecting mechanism 3 to rotate in the clockwise direction, and can also drive the connecting mechanism 3 to rotate in the counterclockwise direction, because the connecting mechanism 3 of this embodiment is fixedly connected under the clamping action of the friction disc of the pneumatic brake, no matter the rotation trend of the connecting mechanism 3 is clockwise or counterclockwise, the pneumatic brake can apply a load in the opposite direction of the rotation trend to the connecting mechanism 3, therefore, the problem that the forward and reverse damping between the connecting mechanism 3 and the cylinder or the weight are mutually offset when the load is loaded by the cylinder or the weight in the prior art can be avoided by using the pneumatic brake with simple structure and relatively low cost, thereby effectively improving the test range of the test, and improving the reliability of the test result of the locking assembly 6.
In some embodiments, as shown in fig. 1 and 2, the load output mechanism 2 further includes a switch 23, a display assembly 24, and an adjustment assembly 25. The switch 23 is connected to the power source 21, and the switch 23 is used to control the start or stop of the power source 21. The display assembly 24 is used for displaying the power value output by the power source 21. The adjustment assembly 25 is used to adjust the power output by the power source 21.
It will be appreciated that the switch 23 ensures that the power source 21 is deactivated to prevent accidental transport of the test device. The display assembly 24 can facilitate a user to observe the load output by the load output mechanism 2 in real time at the testing device, so that the user does not need to move back and forth between the lower computer and the testing device during adjustment, and the testing convenience is improved. The adjustment assembly 25 can facilitate a user in adjusting the load output by the load output mechanism 2 in real time.
Specifically, when the power source 21 is a pneumatic brake, the switch 23 may be provided as a pneumatic control valve capable of controlling the air pressure in the pneumatic brake so as to stop outputting the load. The display assembly 24 can be configured as a high-precision pressure gauge to feed back the air pressure value in the pneumatic brake in real time, so as to obtain the load output by the pneumatic brake in real time according to the air pressure value. The adjusting assembly 25 may be configured as a pressure reducing valve to adjust the load output by adjusting the air pressure in the pneumatic brake, and is also beneficial to improving the stability of the air pressure in the pneumatic brake, and thus the stability of the torque load output of the pneumatic brake.
In some embodiments, as shown in fig. 1 and 2, the connection mechanism 3 comprises a brake disc 31 and a transmission shaft 32. The brake disc 31 is detachably connected to the output of the load output 2. One end of the transmission shaft 32 is connected with the brake disc 31, and the other end is detachably connected with the locking assembly 6.
It can be understood that the brake disc 31 can be conveniently matched with the load output mechanism 2, and the transmission shaft 32 can be conveniently matched with the locking assembly 6, so that the actual operation environment of the locking assembly 6 can be better simulated, and the test reliability of the locking assembly 6 is improved.
In some embodiments, as shown in fig. 1 and fig. 2, the brake disc 31 is provided with a limiting hole, one end of the transmission shaft 32 is fitted in the limiting hole, the locking assembly 6 is provided with a limiting opening 61, the other end of the transmission shaft 32 can be fitted in the limiting opening 61, and both the limiting hole and the limiting opening 61 are used for limiting the circumferential rotation of the transmission shaft 32.
It can be understood that, because the limiting hole and the limiting opening 61 can both limit the circumferential rotation of the transmission shaft 32, when the load output mechanism 2 outputs a torque load through the brake disc 31, the transmission shaft 32, the brake disc 31 and the locking assembly 6 cannot rotate relatively, so that the test reliability of the locking assembly 6 is ensured. Meanwhile, the limiting port 61 and the limiting hole are convenient for dismounting the locking assembly 6, the connecting mechanism 3 and the load output mechanism 2, so that the whole testing device is favorable for transportation and use, and the use convenience is improved.
Particularly, in this embodiment, the cross section of the matching portion of the transmission shaft 32 and the limiting opening 61 and the limiting hole may be set to be a polygon, and the cross section of the limiting opening 61 and the limiting hole may also be set to be a polygon, so that the limiting effect can be better achieved. For example, may be arranged as a pentagon, hexagon, etc.

It can be understood that the driving module 41 can not only drive the transmission terminal to be separated from the connector, but also better ensure that the transmission terminal is stably matched with the connector, thereby preventing the problem that the transmission terminal is separated from the connector or is not well matched with the connector in the testing process, and improving the reliability of the test.
In some specific embodiments, as shown in fig. 1 and 2, the testing assembly 42 includes a harness box 421 and a probe 422, the harness box 421 is connected to the output end of the driving module 41, the probe 422 is disposed on the harness box 421, and the probe 422 can be matched with the connector.

In some embodiments, as shown in fig. 1 and 2, the signal transmission mechanism 4 further comprises a guide 43, the testing component 42 is connected with the guide 43, and the guide 43 is used for guiding the testing component 42.
It can be understood that the guide 43 can guide the movement of the testing component 42 to prevent the testing component 42 from deviating from the moving direction during the movement, thereby preventing the testing component 42 and the connector from interfering and damaging, and prolonging the service life of the testing device.
