[0002] With the continuous development of the automotive industry, more and more cars are choosing to be equipped with electronic parking brake systems. Their convenient and comfortable operation makes them a top choice for many car buyers. Among these, cable-operated electronic parking brake systems are widely used due to their simple structure, low cost, and ease of adoption in various car models.

[0003] However, during the development of cable-operated electronic parking brake (EPB) systems, it is necessary to test the actual output force of the EPB actuator to verify its reliability and durability. Currently, however, there is no suitable dedicated testing equipment to verify the operational durability of the EPB actuator. The EPB actuator must be installed on a vehicle to test its stability and durability, making the entire testing process time-consuming, labor-intensive, and inefficient.

[0019] Example 1 This utility model provides an EPB durability testing device, such as Figures 1-3 As shown, it includes a tooling base plate 1, on which an actuator fixing fixture and a load loading test fixture are provided. The actuator fixing fixture includes an actuator fixing mechanism, an actuator fixing base 14, and an actuator bearing mechanism.

The fixed base 13 is mounted on the tooling base plate 1, and the support block 12 is mounted on the fixed base 13. The head of the EPB actuator 15 is mounted on the support block 12. The support block 12 is used to resist the reaction force of the EPB actuator 15 during the clamping process.

[0021] The actuator mounting base 14 is mounted on the tooling base plate 1, and the actuator fixing mechanism is fixed to the actuator mounting base 14 by bolts. The actuator fixing mechanism includes a hinge support 17, a push rod 16, a connecting rod 18, a rocker arm 19, and an adjusting pressure rod 20. The hinge support 17 is mounted on the actuator mounting base 14, and the push rod 16 and the rocker arm 19 are connected to the hinge support 17. The connecting rod 18 connects the push rod 16 and the rocker arm 19, and the adjusting pressure rod 20 is mounted on the rocker arm 19.

[0022] The push rod 16 and rocker arm 19 are connected to the hinge support 17 via a pin, and the rocker arm 19 and push rod 16 are connected to the connecting rod 18 via a pin. The adjusting rod 20 is connected to the rocker arm 19 via a thread. In use, turning the adjusting rod 20 will press down the adjusting rod 20 to fix the EPB actuator 15 on the actuator fixing base 14, and at the same time, it will serve a positioning function.

Its head abuts against the bearing block 12, and the steel wire core 11 pulled out by the EPB actuator 15 is connected in the core wire slot 8.

[0026] When the EPB actuator 15 operates, it pulls the steel wire core 11.
