Lithium ion battery pack capable of adjusting shift gravity center

Abstract

The invention discloses a lithium ion battery pack capable of adjusting the shift gravity center. The lithium ion battery pack comprises a shell and a left and right shift screw rod mechanism, wherein the left and right shift screw rod mechanism is arranged on a base plate in an inner cavity of the shell, and comprises a gear module, a screw rod and a fixed support; the center of the gear module penetrates through and is screwed on the screw rod; the rear surface of the fixed support is connected with the screw rod; a lithium ion battery pack body is fixed on the top surface of the fixed support, and is positioned in the shell; when the gear module is adjusted, the gear module drives the screw rod to rotate; the screw rod drives the fixed support and the lithium ion battery pack body to move left and right. When the lithium ion battery pack provided by the embodiment is applied to an automobile model, the shift gravity center of the lithium ion battery pack can be regulated according to requirements of users, so that application of users is facilitated.

Description

technical field [0001] The invention relates to the field of lithium-ion battery packs, in particular to a lithium-ion battery pack with an adjustable offset center of gravity. Background technique [0002] At present, there are more and more world car model championships, and most of the current competition regulations are speed competitions. The participating car models must run to the front in the shortest time in order to win the competition ranking; the car model competition track is basically curved. On the road, the vehicle must slow down when passing the turn on the track, so as to ensure that the vehicle can avoid the danger of tilting and overturning when turning at high speed. [0003] The inventor finds in the course of carrying out the research of the present invention, there is following defect in the prior art lithium-ion battery pack for model car: [0004] At present, the battery packs for car model competitions use the existing lithium-ion battery packs in...
