[0002] Door hinges are hidden components that enable the opening and closing of car doors. They are crucial retaining components of the entire door system and also safety components. Currently, hinges are mainly divided into steel hinges, stamped hinges, and forged hinges. They are essential functional components for enabling the opening and closing of car doors; at the same time, they are also safety components of the entire vehicle and are closely related to the vehicle's collision performance. Regulations require that during a collision, the car doors remain closed and locked; after a collision, the car doors should be able to open. Because of the important role of door hinges in vehicle safety, strength testing of door hinges is necessary.

[0003] A search revealed that Chinese Patent CN219625031U discloses a door hinge strength testing device, including a base with a fixing bracket fixedly connected to the upper left side of the base. This door hinge strength testing device utilizes a drive motor to drive a drive gear, which moves along a transmission rack, thereby causing movement on the right side of the car door body to simulate the opening and closing of the door and test the hinge's opening and closing. However, the drive gear in this device bears the weight of the car door body, making it impossible for the hinge to support the full weight of the door body, thus affecting the device's testing accuracy.

[0004] Therefore, it is necessary to improve the existing technology to solve the above-mentioned technical problems. Utility Model Content
