[0034] As a crucial component of vehicle security, the performance of car door locks directly impacts the safety of the vehicle and its occupants. To ensure the reliability and security of car door locks, comprehensive testing is necessary.

[0035] Please see Figure 1 and Figure 2 The vehicle door lock testing device provided in the embodiments of this application will now be described. The vehicle door lock testing device includes:

[0036] Fixing component 1; Fixing component 1 is used to fix the door lock;

[0037] Conveying assembly 2; fixing assembly 1 is disposed on conveying assembly 2, and conveying assembly 2 is used to convey the door lock on fixing assembly 1 to the test station;

[0038] Locking component 3; Locking component 3 is used to lock the door lock at the test station;

[0039] At least one test component; the test component is used to test the door lock located at the test station.

[0040] The main function of the fixing component 1 is to firmly secure the door lock, ensuring that it will not move or fall off during testing, thereby guaranteeing the accuracy and safety of the test. The fixing component 1 can be implemented using methods such as clamping, holding, or bolt tightening. For example, clamping can be achieved using a cylinder; the holding device can be designed with adjustable clamping arms, allowing for adjustments to the spacing and force of the clamping arms to accommodate different door lock models.

[0041] Conveying assembly 2 is responsible for transporting fixed assembly 1 and its attached door locks from the initial loading position to the testing station. Conveying assembly 2 may take the form of a conveyor belt, slide rail, or robotic arm. Conveying assembly 2 may also be equipped with sensors and controllers to monitor the position of fixed assembly 1. Conveying assembly 2 can be configured for reciprocating transport to facilitate the loading and unloading of door locks.

[0042] Locking component 3 is used to precisely lock the door lock in a predetermined position at the test station to prevent the door lock from moving during testing. Locking component 3 can employ methods such as pressure locking or locating pin locking. Taking the latter as an example, locking component 3 can be designed as a locating pin system driven by a cylinder or electric push rod. When the fixing component 1 is delivered to the test station, the locating pin automatically extends and inserts into the locating hole, thereby locking the door lock at the test station.

[0043] The testing components are used to perform performance tests on the door locks located at the testing station. Performance testing can include several aspects of door lock performance, primarily encompassing mechanical, electrical, and functional testing. Specifically, the door lock must have both a fully locked and a partially locked position, and maintain this locked state under varying loads and accelerations. For example:

[0044] Locking and unlocking force: This test measures the force required for the door lock to lock and unlock, ensuring reliable locking and unlocking while facilitating user operation.

[0045] Motor performance: Test the operating voltage, current, speed, torque and other parameters of the door lock motor to ensure that it can provide sufficient power to drive the door lock.

[0046] Child lock function: Test whether the child lock function is working properly to prevent children from accidentally opening the car door.

[0047] Emergency unlocking function: Test whether the car door can be opened mechanically in the event of a power outage or other emergency.

[0048] The testing process is as follows:

[0049] First, install the door lock onto the fixing component 1, ensuring it is securely fixed. Then, activate the conveying component 2 to transport the fixing component 1, with the door lock attached, from its initial position to the testing station. When the fixing component 1 arrives at the testing station, the locking component 3 locks the door lock in place. Next, activate the testing component to perform various tests on the door lock.

[0050] Since multiple tests are often performed on car door locks, involving multiple test components, the area near the testing station contains numerous components, making direct installation of the door locks difficult. Therefore, in this embodiment, the door lock is installed on a fixing component 1, then transported to the testing station via a conveying component 2, and locked in place at the testing station by a locking component 3. This significantly improves the convenience of door lock testing and facilitates the arrangement of test components. For example, the conveying component 2 can be placed on one side of the testing station, and multiple test components can be placed on the other sides of the testing station. Figure 1 In the illustrated embodiment, the conveying station is located behind the testing station, the emergency lock testing component 6 is located in front of the testing station, and the locking / unlocking testing component 5 is located above the testing station. Compared to manual testing, the door lock testing device of this embodiment can significantly improve testing efficiency, accuracy, and consistency. Figure 2 As shown, multiple test stations can be set up, and each test station is equipped with a corresponding fixed component 1, conveying component 2, locking component 3 and test component.

[0051] In some embodiments of this application, the test components may refer to the following test items:

[0052] Double-pull opening: The inward-opening mechanism uses double-pulling to centrally control and unlock the door. The first pull of the inward handle deactivates the anti-theft mechanism, and the second pull unlocks the door. The specific testing method involves locking the lock body and engaging the central locking system, then manipulating the inward-opening mechanism to observe the lock's functionality.

[0053] Central locking, external opening does not unlock: This function prevents the doors from being opened from the outside by using the central locking and unlocking functions. The specific testing method is as follows: when the central locking system is engaged, moving the external opening arm in the unlocking direction should not change the central locking status, nor should it change the mechanical locking status or signal; the electronic lock should not show any such signal.

[0054] Operating the outward and inward opening mechanisms does not change the central locking status, and both inward and inward opening are disabled: When the superlock is engaged, operating the inward and inward opening mechanisms does not change the central locking status, and both inward and inward opening are disabled. Specifically, after the central locking is engaged, the superlock is engaged simultaneously, and then the inward and inward opening mechanisms of the door locks are operated.

[0055] When the super lock motor is not secured, it does not affect the locking and unlocking operations of the central control motor: When the super lock motor is not secured, the central control motor can be locked and unlocked.

[0056] Lock cylinder test: The central locking and unlocking functions are controlled by the external mechanical lock cylinder of the car door, and the function of preventing the car door from being opened from the outside can also be tested.

[0057] Internal opening test: When the super lock is unlocked, the door lock is operated in a simulated real vehicle state. The internal opening arm can unlock and open the door lock mechanism normally.

[0058] Emergency Lock Test: When the vehicle's power is depleted or the remote key fails, the emergency locking mechanism of the door locks activates the central locking function to prevent the doors from being opened from the outside. Specifically, the emergency lock knob is moved to the engaged position; pulling the outward-opening lever will not unlock the door. The central locking system then disengages the lock, and pushing the emergency lock knob back to the disengaged position with the central locking lever engaged will release the lock.

[0059] Please see Figure 3 In some embodiments of this application, the fixing component 1 includes a fixing plate 11 and a first pressing mechanism 13. The fixing plate 11 is provided with a receiving groove 12 for placing a car door lock. The first pressing mechanism 13 is disposed toward the receiving groove 12 and is used to press the car door lock to restrict the car door lock within the receiving groove 12.

[0060] The mounting plate 11 is a fundamental component that provides a stable platform for holding the door lock. A specific receiving slot 12 is designed into the mounting plate 11. The shape and size of this receiving slot 12 are designed according to the shape and dimensions of the door lock to ensure that the door lock can be accurately placed and remain stable within it. The mounting plate 11 can be made of metal or plastic to ensure its strength and durability. The shape and size of the receiving slot 12 are determined based on the specific design of the door lock and can be achieved using CNC machining or other precision manufacturing techniques to ensure accuracy.

[0061] The first clamping mechanism 13 is positioned facing the receiving groove 12. The function of the first clamping mechanism 13 is to firmly retain the door lock within the receiving groove 12 by pressing against it. This prevents the door lock from moving or falling off during processing, testing, or transportation, ensuring operational accuracy and safety. The first clamping mechanism 13 can be implemented in various ways. For example, it can be implemented using a spring, a pneumatic cylinder, or a hydraulic cylinder.

[0062] When the door lock needs to be secured using the fixing component 1, the door lock is first placed into the receiving groove 12 on the fixing plate 11. Then, the first clamping mechanism 13 is activated or operated to apply pressure to the door lock within the receiving groove 12. This pressure firmly secures the door lock within the receiving groove 12, thus completing the fixing process.

[0063] In addition, the mounting plate 11 can be installed in a detachable manner, so that the mounting plate 11 with the corresponding receiving slot 12 can be replaced for different door locks, while other structures of other fixing components 1 can be universal.

[0064] Please see Figure 3In some embodiments of this application, the test assembly includes a lock cylinder test assembly 4, which includes a first drive mechanism 42 and a door key 41. The door key 41 is located on the side of the receiving groove 12 away from the first pressing mechanism 13. The receiving groove 12 is provided with a hollow portion for exposing the lock cylinder of the door key 41 on the side away from the first pressing mechanism 13. The door key 41 is used to rotate the lock cylinder exposed from the hollow portion. The first drive mechanism 42 is used to drive the door key 41 to rotate.

[0065] The lock cylinder testing assembly 4 can be used to test the lock cylinder function and the functions related to outward-opening doors. The door key 41 is a key that matches the door lock cylinder and is used to simulate the insertion and rotation of a real key during testing. The door lock is placed in the receiving groove 12, with a cutout on one side of the groove to expose the lock cylinder. The door key 41 is also located on the side of the receiving groove 12 opposite to the first pressing mechanism 13, so that when the first pressing mechanism 13 presses the door lock into the receiving groove 12, the door key 41 can be smoothly inserted into the door lock from the opposite side. The first drive mechanism 42 is used to drive the door key 41 to rotate, thereby causing the door key 41 to rotate the lock cylinder. The first drive mechanism 42 can adopt a structure such as an electric motor or a hydraulic motor. To enable precise control of the rotation of the door key 41 by the first drive mechanism 42, a servo motor can be used.

[0066] Please see Figure 4 In some embodiments of this application, the conveying component 2 includes a second driving mechanism 22 and a first guide rail 21. The fixing component 1 is disposed on the first guide rail 21. The second driving mechanism 22 is connected to the fixing component 1 and is used to drive the fixing component 1 to move along the first guide rail 21.

[0067] The conveying assembly 2 is used to convey the door lock on the fixed assembly 1 to the testing station. In this embodiment, the conveying assembly 2 includes a second drive mechanism 22 and a first guide rail 21. The first guide rail 21 provides a track for the movement of the fixed assembly 1. The second drive mechanism 22 is connected to the fixed assembly 1 and is used to drive the fixed assembly 1 to move along the first guide rail 21. The second drive mechanism 22 can be an electric motor, a pneumatic device, or a hydraulic cylinder. Figure 4 In the illustrated embodiment, the second drive mechanism 22 employs a leverless cylinder, which, in conjunction with the first guide rail 21, enables the forward and backward movement of the fixed component 1. Furthermore, a limit switch can be provided to control the conveying position of the fixed component 1.

[0068] Please see Figure 1 In some embodiments of this application, the locking component 3 includes a second pressing mechanism for pressing the door lock into the test station.

[0069] The second clamping mechanism is the core component of the locking assembly 3, used to press the door lock firmly onto the test station to prevent movement or shaking during testing. The second clamping mechanism can be mechanical, pneumatic, or hydraulic, depending on the required clamping force and precision. Figure 1 In the embodiment shown, the second clamping mechanism uses a cylinder, which is installed above the test station.

[0070] Please see Figure 5 In some embodiments of this application, the test component includes an opening and closing test component 5, which includes a third drive mechanism 51, a first pressure sensor 52, and a lock tongue 53. The first pressure sensor 52 is connected between the third drive mechanism 51 and the lock tongue 53. The third drive mechanism 51 is used to drive the lock tongue 53 to enter or exit the door lock.

[0071] The locking / unlocking test assembly 5 is used to simulate and test the locking / unlocking performance of the vehicle door. The latch 53 is responsible for opening and closing the door. During the locking / unlocking test, the latch 53, driven by the third drive mechanism 51, simulates real opening and closing actions. The third drive mechanism 51 is the power source of the locking / unlocking test assembly 5, used to drive the latch 53 into or out of the door lock. The third drive mechanism 51 can be a motor, cylinder, or hydraulic cylinder, etc., the specific choice depending on the required driving force, speed, and accuracy. Figure 5 In the illustrated embodiment, the third drive mechanism 51 employs a servo motor and lead screw structure, enabling precise control of the latch 53 to simulate full and partial lock states. A first pressure sensor 52 is connected between the third drive mechanism 51 and the latch 53 to monitor the resistance or pressure experienced by the latch 53 during the process of entering and exiting the door lock, thereby testing the force required to open and close the door lock.

[0072] Please see Figure 6 In some embodiments of this application, the test component includes an emergency lock test component 6, which includes an emergency contouring component 61, a fourth drive mechanism 62, and a fifth drive mechanism 63. The fourth drive mechanism 62 is used to drive the emergency contouring component 61 to insert into the door lock, and the fifth drive mechanism 63 is used to drive the emergency contouring component 61 to rotate.

[0073] The emergency lock test assembly 6 is a key component used to simulate and test the unlocking performance of the vehicle door lock in an emergency. The emergency contour piece 61 is a component whose shape matches the emergency lock hole of the vehicle door lock, used to simulate an emergency lock key or tool. The design of the emergency contour piece 61 must ensure that it can be smoothly inserted into the emergency lock hole of the vehicle door lock and that it can trigger the emergency lock unlocking mechanism upon rotation. The fourth drive mechanism 62 is responsible for driving the emergency contour piece 61 to insert into the emergency lock hole of the vehicle door lock. Once the emergency contour piece 61 is inserted into the lock hole, the fifth drive mechanism 63 begins to operate, driving the emergency contour piece 61 to rotate within the lock hole. This rotational action simulates the rotation process of an emergency lock key, used to trigger the unlocking mechanism.

[0074] The fifth drive mechanism 63 also needs precise rotation control and stable driving force. The fourth drive mechanism 62 can be an electric actuator or a cylinder, and the fifth drive mechanism 63 can be an electric rotary device or a pneumatic rotary motor. In such cases... Figure 6 In the embodiment shown, the fourth drive mechanism 62 may be a cylinder, and the fifth drive mechanism 63 may be a servo motor.

[0075] Please see Figure 6 In some embodiments of this application, the test component includes a child lock test component 7, which includes a sixth drive mechanism 71 and a lever 72. The sixth drive mechanism 71 is connected to the lever 72 and is used to drive the lever 72 to open or close the child lock of the car door.

[0076] The child lock test assembly 7 is used to simulate and verify whether the child lock function of the car door lock is working properly. The sixth drive mechanism 71 is the power source for the child lock test assembly 7, responsible for driving the lever 72. The sixth drive mechanism 71 can be electrically, pneumatically, or hydraulically driven, depending on the overall design and requirements of the test system. The lever 72 is the component that directly contacts the child lock mechanism of the car door lock, used to simulate the process of operating the child lock. Figure 6 In the embodiment shown, the sixth drive mechanism 71 is driven by a cylinder.

[0077] Please see Figure 7 In some embodiments of this application, the test assembly includes a cable test assembly 8, which includes a cable fixing member 81, a toggle member 82, a second sensor 83, and a seventh drive mechanism 84. The cable fixing member 81 is used to fix the cable of the door lock. The second sensor 83 is connected between the toggle member 82 and the seventh drive mechanism 84. The seventh drive mechanism 84 is used to drive the toggle member 82 to toggle the cable fixing member 81 to pull the cable of the door lock.

[0078] The cable test assembly 8 is used to simulate and verify the reliability and functionality of the door lock cable. The cable is typically an inward-opening drive structure for the door. In the cable test assembly 8, the cable fixing member 81 is used to secure the door lock cable, ensuring its stability during testing. The cable fixing member 81 is designed to match the shape and size of the cable to ensure it is firmly secured. The actuating member 82 is a component that contacts the cable fixing member 81, pulling or releasing the cable through interaction with it. The actuating member 82 is designed to smoothly and stably actuate the cable fixing member 81, thus simulating the actual working state of the door lock cable. The second sensor 83 monitors the movement of the actuating member 82 to test the opening force of the cable. The seventh drive mechanism 84 is the power source for the cable test assembly 8, used to drive the actuating member 82. It can be electrically, pneumatically, or hydraulically driven, depending on the overall design and requirements of the test system. Figure 7 In the embodiment shown, the seventh drive mechanism 84 uses a servo motor in conjunction with a lead screw to achieve drive.

[0079] Before the cable test begins, the door lock is secured in the test station, and the cable is correctly connected to the cable fixing member 81. When the test system receives the cable test command, the seventh drive mechanism 84 starts working, driving the actuating member 82 to move in the specified direction to actuate the cable fixing member 81 and pull the door lock cable. During this process, the second sensor 83 monitors the force on the actuating member 82 in real time. The seventh drive mechanism 84 continues to work until the predetermined test conditions are met or the specified test steps are completed. During this process, the test system collects relevant data through the second sensor 83. Then, the test system analyzes this data to evaluate the performance and reliability of the cable.

[0080] Please see Figure 7 In some embodiments of this application, the cable fixing member 81 is disposed on the fixing component 1, and the conveying component 2 can convey the fixing component 1 along the first direction so that the cable fixing member 81 corresponds to the actuating member 82 in the second direction. The second direction is perpendicular to the first direction, and the actuating member 82 is used to actuate the cable fixing member 81 along the second direction.

[0081] Because the door lock is fixed to the fixing assembly 1, the cable fixing member 81 is mounted on the fixing assembly 1. This allows the cable to be secured when the door lock is fixed, and it will not be affected by subsequent transport. Due to space constraints, the other components of the cable testing assembly 8 are difficult to mount on the fixing assembly 1, and therefore, they will not move with the fixing assembly 1. To allow the actuating member 82 to move the cable fixing member 81... Figure 7As shown, A represents the first direction and B represents the second direction. When the conveying component 2 conveys the fixing component 1 along the first direction, the cable fixing component 81 can be aligned with the actuating component 82 in the second direction. In this way, the actuating component 82 can be used to move the cable fixing component 81 along the second direction. The second direction is perpendicular to the first direction, ensuring that the actuating component 82 will not affect the movement of the fixing component 1.

[0082] To ensure the stability of the cable fixing component 81, the cable fixing component 81 can be set on a track arranged along the second direction, while the actuating component 82, the second sensor 83 and the seventh drive mechanism 84 can also be set on a track arranged along the first direction, so that they can be adjusted as a whole along the first direction, thereby ensuring that the positions of the actuating component 82 and the cable fixing component 81 correspond.

[0083] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
