[0027] Please refer to Figures 1-3The electric vehicle trunk upper cover disclosed in the application comprises an upper cover body, a hinge part 1 is arranged on the upper cover body, and the hinge part 1 is specifically a shaft connecting structure provided with a shaft hole, which can be hinged to the trunk body through cooperation with a rotating shaft.
[0028] A plurality of combined clamping joints 2 are arranged on the inside of the opening part of the upper cover body, and the combined clamping joint 2 comprises a clamping head 21 and a clamping groove 22.
[0029] The clamping head 21 comprises a clamping head 211, the bottom of the clamping head 211 is provided with a buffer cavity 212, and the clamping head 211 is provided with an elastic deformation position 213; the elastic deformation position 213 can be elastically deformed inwardly when the clamping head 211 is subjected to the circumferential clamping action of the corresponding clamping groove to avoid hard abrasion. The buffer cavity 212 can buffer the vertical pressure received by the clamping head 211.
[0030] The clamping groove 22 comprises a clamping groove 221 and a plurality of groove-in clamping heads 222; the groove-in clamping heads 222 are arranged in parallel in the clamping groove 221. The groove-in clamping head 222 comprises a horizontal extension 223 and a vertical extension 224; the horizontal extension 223 is arranged on the groove bottom of the clamping groove 221, and the vertical extension 224 extends vertically along the side wall of the clamping groove 221; the horizontal extension 223 and the vertical extension 224 are integrally formed and are connected at the groove bottom part of the clamping groove 221. One groove-in clamping position 225 is defined between every two adjacent groove-in clamping heads 222.
[0031] The groove-in clamping head 222 can be elastically deformed to buffer the hard impact when the corresponding clamping head on the trunk body is inserted into the groove-in clamping position 225. The plurality of groove-in clamping positions 225 arranged in parallel can form multi-point embedded connection with the corresponding clamping head on the trunk body, which is beneficial to improve the stability of the cover.
[0032] In a changed embodiment of the application, the size of the upper end of the vertical extension 224 is greater than that of the rest of the vertical extension 224 to form an anti-loosening structure.
[0033] In a changed embodiment of the application, a single clamping head 3 is further arranged on the upper cover body, and the single clamping head 3 has the same structure as the clamping head 21 of the combined clamping joint 2. The single clamping head 3 can increase the number of connection points to balance the stress of the upper cover body when it is opened and closed and prevent local deformation of the body.
[0034] In a changed embodiment of the application, in order to improve the locking effect between the trunk upper cover and the trunk body, a transverse lock catch 4 is further arranged on the upper cover body. The transverse lock catch 4 comprises a lock catch groove 41, and the groove body of the lock catch groove 41 is provided with a locking hole 42 perpendicular to the groove body. The elastic member such as a wave bead screw assembled in the locking hole 42 can form a transverse locking action.
