[0025] Please refer to Figures 1-3 , the three-dimensional connecting electric vehicle trunk provided by the application comprises a trunk main body 1; the trunk main body 1 is a square trunk, and the fixed connection between the trunk main body 1 and the trunk upper cover is established through a plurality of three-dimensional connectors 2; the three-dimensional connectors 2 are arranged at the opening edge position of the trunk main body 1 and are symmetrically distributed.

[0026] The three-dimensional connector 2 comprises a buffer cavity 24; a vertical clamping head 23 is arranged on the buffer cavity 24; a left clamping head 25 and a right clamping head 26 are further arranged on the buffer cavity 24; the left clamping head 25 and the right clamping head 26 are respectively located on the left and right sides of the vertical clamping head 23; the left clamping head 25 and the right clamping head 26 and the trunk body 1 define a parallel clamping groove 21; the left clamping head 25 and the right clamping head 26 and the vertical clamping head 23 define a vertical clamping groove 22. The vertical clamping head 23 has a cylindrical structure and is provided with a vertical positioning hole 27.

[0027] The parallel clamping groove 21, the vertical clamping groove 22 and the vertical clamping head 23 are respectively used to establish the clamping connection between the trunk body 1 and the trunk upper cover in the parallel direction, the vertical direction and the vertical direction of the edge of the trunk body 1. Among them: the parallel direction is the direction parallel to the edge of the trunk body (or called the circumferential direction), the vertical direction is the direction perpendicular to the edge of the trunk body (or called the normal direction), and the vertical direction is the direction perpendicular to the parallel direction and the vertical direction.

[0028] Therefore, any two directions among the circumferential direction, the normal direction and the vertical direction are orthogonal in space, forming an XYZ three-axis connection structure.

[0029] The buffer cavity 24 comprises a left buffer chamber 241 and a right buffer chamber 242; a chamber partition plate 243 is arranged between the left buffer chamber 241 and the right buffer chamber 242. The vertical clamping head 23 is arranged at the outer side connecting position of the left buffer chamber 241 and the right buffer chamber 242; the left clamping head 25 and the right clamping head 26 are respectively arranged at the outer side edge position of the left buffer chamber 241 and the right buffer chamber 242.

[0030] The buffer cavity 24 is used to buffer the pressure received by the three-dimensional connector 2 through elastic deformation, so as to avoid the rigid cooperation such as hard plugging or hard clamping between the three-dimensional connector 2 and the connecting and cooperating structure on the trunk upper cover.

[0031] Principle and effect description: after the three-dimensional connector 2 and the connecting and cooperating structure on the trunk upper cover are connected, the parallel clamping groove 21 applies the connecting force from the circumferential direction, the vertical clamping groove 22 applies the connecting force from the normal direction, and the vertical clamping head 23 applies the connecting force from the vertical direction, so as to form the XYZ three-axis connection structure which is orthogonal in pairs. Compared with the connection mode in the same dimension, it is helpful to increase the mechanical strength of the connecting position and improve the reliability of the connection.

[0032] In a changed embodiment of the present application, the trunk body 1 is a circular trunk. Therefore, the parallel clamping groove 21 in the circumferential direction is in an arc shape, the vertical clamping groove 22 in the normal direction is in a straight line shape, and the vertical clamping head 23 in the vertical direction is in a straight line shape. The structure and implementation principle of the three-dimensional connector 2 in the circular trunk body are similar to those of the square trunk body, which will not be described here.

[0033] The technical solutions and technical effects of the present application are described in detail above in combination with the accompanying drawings and specific embodiments, and it should be noted that other embodiments can be developed by those skilled in the art on the basis of the present application; any simple modification and equivalent replacement without departing from the innovative concept of the present application are covered by the present application and belong to the protection scope of the present patent.
