The fourth cylinder 16 cooperates with the closing block 13 to provide sufficient closing driving force for the vehicle door and ensure a certain speed requirement when the vehicle door is closed.

[0044] In combination with Figure 1 When the test device in the technical scheme of the present application is used for detecting the durability performance of the vehicle door, three mechanisms are mainly used to complete the detection. First, the second cylinder 26 in the side door opening and unlocking mechanism 60 drives the unlocking gripper to open and close to realize the gripping action of the side door handle, and the first cylinder 30 drives the unlocking gripper to move to finally realize the unlocking action. At this time, the side door has been pulled open to a certain gap. Then, the third cylinder 5 of the side door secondary opening mechanism 61 drives the second swing arm 11 to swing around the rotating shaft to make the door opening hook hand hook the edge of the side door, and cooperates with the driving assembly of the driving seat 59 to drive the first swing arm 49 to swing around the rotating center to open the side door. Finally, the fourth cylinder 16 of the side door closing mechanism 62 drives the closing block 13 to move to realize the closing action of the side door. The technical scheme of the present application divides the unlocking of the side door and the opening of the side door into two actions, which are respectively executed by the side door opening and unlocking mechanism 60 and the side door secondary opening mechanism 61. The scheme of directly using the unlocking gripper to execute the opening action is abandoned. The edge of the side door is hooked by the side door secondary opening mechanism 61, and the opening action is further realized by the first swing arm 49. The rotating center of the first swing arm 49 and the hinge of the vehicle door do not need to be arranged on the same axis line during the operation, so that the adverse effect of the rotating center of the first swing arm 49 and the hinge of the vehicle door not being arranged on the same axis line on the door lock can be avoided.

[0045] In some embodiments, referring to Figure 4 , Figure 5 The side door opening and unlocking mechanism 60 further includes a first mounting seat 42 and an extension support 25. The first mounting seat 42 is provided with a first guide rail for guiding the unlocking action. The extension support 25 extends from the first end to the second end along the direction of the first guide rail, and the extension support 25 is a lengthened support. The extension support 25 is mounted on the first guide rail through a first sliding block, and the first cylinder 30 is mounted on the first mounting seat 42 through a cylinder support 29. The output end of the first cylinder 30 is connected with the first end of the extension support 25, and is used for driving the extension support 25 to move along the first guide rail to realize the unlocking action.

[0046] The unlocking gripper includes a first unlocking hook 27 and a second unlocking hook 39 hinged to the second end of the extension bracket 25. Both the first unlocking hook 27 and the second unlocking hook 39 are arc-shaped hooks, forming an openable and closable gripper structure. A second cylinder 26 is mounted on the extension bracket 25. The output end of the second cylinder 26 extends along the direction of the first guide rail to the space between the first unlocking hook 27 and the second unlocking hook 39. The output end of the second cylinder 26 is provided with a hinge shaft 34, which is connected to the first unlocking hook 27 and the second unlocking hook 39 on both sides via a connecting rod 35. The second cylinder 26 is used to drive the first unlocking hook 27 and the second unlocking hook 39 to perform a gripping action.

[0047] Combination Figure 4 , Figure 5 When unlocking the car side door handle, the second cylinder 26 drives the first unlocking hook 27 and the second unlocking hook 39 to open. The first cylinder 30 drives the extension bracket 25 to move along the first guide rail, bringing the unlocking gripper at the second end of the extension bracket 25 closer to the car side door handle. The second cylinder 26 then drives the first unlocking hook 27 and the second unlocking hook 39 to close. The first cylinder 30 then drives the extension bracket 25 to move in the opposite direction along the first guide rail, thus cooperating with the unlocking gripper to achieve the unlocking action. The technical solution of this invention can simulate the action of a real human hand, avoiding abnormal damage to the car door handle. Simultaneously, the unlocking gripper uses the first unlocking hook 27 and the second unlocking hook 39 hinged to the second end of the extension bracket 25. Cooperating with the second cylinder 26 to extend and retract along the first guide rail, this unlocking gripper effectively reduces the weight at the front end of the unlocking mechanism and improves the accuracy of the unlocking action.
