Abstract

The invention discloses an expansion type locating pin and belongs to the technical field of new energy automobiles. The expansion type locating pin is designed to solve the technical problems that the comfort level of a user driving a vehicle is relatively low as a battery pack swings obviously and the locating precision of the battery pack and a vehicle body is not high and the like. The expansion type locating pin is used for fixing the battery pack to the vehicle body and comprises a locating pin sleeve, a protrusion, expansion blocks and a cover plate. A through hole is formed in the locating pin sleeve, at least one protrusion block is arranged, a connecting turnup is arranged on the peripheral edge of each protrusion, the connecting turnup leans against the inner circumferential wall of the locating pin sleeve, the protrusions are arranged by penetrating the through hole and are arranged outside the locating pin sleeve in a protruding manner, the cover plate is closed at an opening of the locating pin sleeve, the expansion block is placed in a space formed by the locating pin sleeve and the cover plate, and the expansion block leans against the connecting turnups. The expansion type locating pin limits a battery pack play phenomenon effectively, so that the battery pack and the vehicle body are located precisely, and the comfort level of the user driving the vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to an expansion type positioning pin. Background technique [0002] During the production of new energy vehicles, battery packs need to be installed on the body. In the prior art, a cylinder is used to fix the battery pack on the vehicle body, but due to the large gap between the battery pack and the cylinder, the battery pack is easy to move, especially when the car brakes suddenly and the road is uneven. The package shaking is more obvious, the positioning accuracy of the battery pack and the body is not high, and the user's driving comfort is low. Contents of the invention [0003] The purpose of the present invention is to provide an expansion-tight positioning pin, which effectively limits the movement of the battery pack, ensures the precise positioning of the battery pack and the vehicle body, and improves the comfort of the user driving the vehicle. [0004] ...
