In the accompanying drawings, for the sake of clarity, the thickness of the layers and regions may be enlarged, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0043] Combination Figures 1 to 4 As shown, according to a specific embodiment of the present application, a support device for leaf spring testing is provided.

[0044] Specifically, the support device includes a first base 1 and a support base. There are two first bases 1, and the two first bases 1 are arranged at intervals along a preset direction. There are multiple support bases, and any support base is detachably connected to any first base 1. The support base is provided with a support portion for connecting to a leaf spring. The structure of the support portion of at least one of the multiple support bases is set differently from the structure of the support portions of the remaining support bases. The support base is replaced to cooperate with the first base 1 to adapt to leaf springs of different structures.

[0045] It should be noted that, according to the installation position of the leaf spring, the leaf spring is divided into a front leaf spring and a rear leaf spring. The connecting parts on both sides of the front leaf spring are coiled ears, and the connecting parts on both sides of the rear leaf spring are flat steel plates.

[0046] In an embodiment of the present application, two first bases 1 are arranged at intervals along a preset direction, there are multiple support bases, any support base is detachably connected to any first base 1, and the support base is provided with a support portion for connecting to a leaf spring, and the structure of the support portion of at least one of the multiple support bases is set differently from the structure of the support portions of the remaining support bases. According to the structure of the leaf spring, an appropriate support base is selected, and the support base is installed on the first base 1 to test the leaf spring. The support device in the above scheme adapts to the test of leaf springs of different structures by replacing the support base, thereby reducing the cost of the support device and thus reducing the test cost.

[0047] Furthermore, the supporting device also includes a second base 2, which is located between the two first bases 1. A positioning member 3 is provided on the top of the second base 2. The positioning member 3 is detachably connected to the second base 2. The positioning member 3 has a first position connected to the actuator clamp of the leaf spring, and a second position detached from the actuator clamp of the leaf spring.

[0048] It should be noted that the actuator clamps the leaf spring and moves it to a preset position so that both sides of the leaf spring are supported on the support base. During the installation of the leaf spring, the positioning member 3 is connected to the actuator clamp to achieve the position positioning of the leaf spring, so that the leaf spring and the support base are stably supported to avoid the leaf spring and the support base from offsetting. After the leaf spring is installed, the positioning member 3 needs to be removed to test the leaf spring.

[0049] In an exemplary embodiment of the present application, the positioning member 3 is a telescopic rod, the positioning member 3 is telescopically arranged along the vertical direction, and the positioning member 3 is threadedly connected to the second base 2 .

[0050] It should be noted that the actuator fixture is provided with a positioning hole, and the actuator fixture is plugged and matched with the telescopic rod through the positioning hole to achieve the positioning of the leaf spring. During the test, the positioning member 3 needs to be removed. Specifically, the telescopic rod is first retracted to be separated from the actuator fixture, and then the telescopic rod is rotated to separate the telescopic rod from the second base 2.

[0051] Furthermore, the supporting device also includes a connecting member 4 , which is connected between the first base 1 and the second base 2 .

[0052] In an exemplary embodiment of the present application, the connecting member 4 is a connecting rod, and a through hole is provided on each of the first base 1 and the second base 2, and the connecting rod is connected to the first base 1 and the second base 2 through the through hole. The arrangement of the connecting member 4 eliminates the need to adjust the first base 1 and the second base 2 separately before installing the leaf spring, thereby saving testing time.
