Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0032] Such as Figure 1 to Figure 5 As shown: this embodiment discloses an electric vehicle battery pack installation and fastening mechanism: it includes a housing 1, a rotating lock block 2 and a locking block, and the battery pack 5 is provided with a laterally extending locking protrusion 51, due to locking The protrusion 51 extends laterally, so the locking protrusion 51 forms a downwardly sloping slope with the portion below the battery pack 5 that does not extend laterally.

[0033] The rotary lock block 2 is hinged to the housing 1 and is provided with a locking slope 21 , and the locking slope 21 is matched with the locking protrusion 51 .

[0034] During use, when the locking block ...

Abstract

The invention discloses an electric automobile battery pack installing and fastening mechanism and an electric automobile, and belongs to the technical field of electric automobiles. The electric automobile battery pack installing and fastening mechanism comprises a shell, a rotary locking block and a locking block, the battery pack is provided with a locking protrusion extending transversely, andthe rotary locking block is hinged to the shell and provided with a locking slope; when the locking block enables the rotary locking block to be in a locking state, the locking inclined plane transversely extends out of the shell and is connected with the locking bulge; and when the locking block enables the rotary locking block to be in a release state, the locking inclined surface shrinks towards the interior of the shell and is separated from the locking bulge. The locking block comprises the locking elastic piece and the elastic piece support arranged in the locking elastic piece, the locking elastic piece can play a role in buffering and shock absorption, and errors in size are compensated to a certain extent. When a battery pack is locked by using a plurality of rotary locking blocks, and after the rotary locking blocks and the locking bulges are repeatedly abraded and worn, the relative positions of the rotary locking blocks and the locking bulges can be automatically adjusted,so that the rotary locking blocks are uniformly stressed to a certain extent.

Description

technical field [0001] The invention relates to the technical field of electric vehicle battery pack installation, in particular to an electric vehicle battery pack installation fastening mechanism and an electric vehicle. Background technique [0002] At present, the battery packs of electric vehicles are all installed with threaded connections, that is, the battery packs are installed and fastened to the vehicle body floor by screws or bolts. The screw connection technology is mature, the structure is simple, the cost is low, and the safety and reliability are relatively high. However, there is an obvious shortcoming of the threaded connection, which is that it cannot be installed and disassembled quickly and repeatedly. The safety and reliability of the threaded connection requires that the contact between the screw / bolt and the nut must be relatively static, in a preset locked state, without looseness, and the force-bearing surface must be uniform, otherwise the threade...
