[0003] Existing technology, CN202023307612.5, still relies on simple testing tools and manual reading for testing the unlocking force of car door locks. Due to factors such as manual reading, the test results are inaccurate, unstable, and inefficient. Furthermore, current testing methods struggle to simulate various real-world usage scenarios, making it difficult to evaluate the performance of car door locks.

[0004] Therefore, it is necessary to design a testing platform that can simulate the unlocking force of car door locks to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a testing platform that can simulate the unlocking force of a car door lock, thereby overcoming the aforementioned shortcomings of the existing technology.

[0016] Reference Figures 1 to 3 A testing bench device capable of simulating the unlocking force of a car door lock includes a testing bracket 1 for testing, a door lock mounting mechanism 2 mounted on the testing bracket, an inner door lock unlocking cable mechanism 3 and an outer door lock unlocking cable mechanism 4 mounted on the testing bracket for use in conjunction with the door lock mounting mechanism, and a control system 5 for receiving and testing the force of the door lock mounting mechanism, the inner door lock unlocking cable mechanism, and the outer door lock unlocking cable mechanism;

[0017] The door lock mounting mechanism 2 includes a mounting bracket 21 placed on the detection bracket, a lock body mounting seat 22 placed on one side of the mounting bracket for mounting the lock body, and a latch adjustment module 23 set on the other side of the mounting bracket for engaging with the lock body.

[0018] The latch adjustment module 23 includes a fixed plate 231 installed at the end of the mounting bracket, a shaft 232 set on the fixed plate, an adjustment base 234 connected by a lead screw 233 and sleeved on the shaft, a latch mounting plate seat 235 placed on the adjustment base, a latch 236 placed on the side of the latch mounting plate seat, an elbow clamp 237 for driving the latch to lock and tighten, a pressure spring 238 sleeved on the shaft and pressing against the adjustment base and the latch mounting plate seat respectively, and a force sensor placed at the bottom of the adjustment base;

[0019] By rotating the lead screw, the position of the adjustment base is adjusted, and the pressure spring is squeezed, which puts pressure on the latch mounting plate. By adjusting the lead screw, the squeezing force of the pressure spring is adjusted, which is then converted into the holding force on the latch mounting plate. The latch is then pressed down and locked into the door lock by the elbow clamp, thereby adjusting the locking force to be tested.

[0020] The inner door lock unlocking cable mechanism 3 and the outer door lock unlocking cable mechanism 4 have the same structure, but are set at different parts of the door lock mounting mechanism. Both the inner and outer door lock unlocking cable mechanisms include an unlocking mounting base 31 set on the detection bracket, a screw adjustment module 32 set on the unlocking mounting base, an unlocking mounting plate 33 driven by the screw adjustment module, a mounting block 34 set on the unlocking mounting plate, a door lock cable threaded connection block 35 set at the end of the mounting block, and a car lock unlocking cable 36 connected to the door lock cable threaded connection block by a threaded connection. The car lock unlocking cable is connected to the corresponding door lock unlocking block. The screw adjustment module is adjusted to drive the unlocking mounting plate to move, thereby driving the car lock unlocking cable to move until the door lock unlocking block is pulled to unlock.

[0021] In order to detect the force applied by the unlocking cord, a sensor is also installed at the end of the unlocking cord;

[0022] The control system includes a control frame, an industrial computer placed inside the control frame, a power supply, and a display mounted on the control frame for displaying detection data.

[0023] Both the force sensor and the sensor are electrically connected to the control system, and the display is used to show the detected data.

[0024] In this implementation, the position of the adjusting base is adjusted by rotating the lead screw, which compresses the pressure spring, thus applying pressure to the latch mounting plate. Adjusting the lead screw further adjusts the spring's compressive force, converting it into a holding force on the latch mounting plate. This adjustment is made as needed until the required force is achieved. The door lock with detection is then installed onto the lock body mounting base, and the latch is engaged in the lock body for locking. The unlocking ropes for the inner and outer door locks are connected to their corresponding unlocking blocks. Adjusting the lead screw module moves the unlocking mounting plate, which in turn moves the unlocking ropes until they pull the unlocking block, unlocking the door lock. Simultaneously, the force required to unlock the door lock is displayed on the monitor, along with the force required to unlock the door lock, thus completing the detection process.

[0025] The advantages of this utility model are that this technical solution sets up an adjustable latch adjustment module to adjust the corresponding door lock adjustment force, and then uses the inner door lock unlocking pull cable mechanism and the outer door lock unlocking pull cable mechanism to unlock the door lock. This detects how much force is required to unlock the corresponding door lock, and the detection results are quickly obtained by the sensors set on the inner door lock unlocking pull cable mechanism and the outer door lock unlocking pull cable mechanism. It can be adjusted according to needs, has high practicality, and converts the collected data into curves, which can be used to conveniently and quickly compare product differences.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
