Embodiment 1

[0034] see Figure 1-4 , an electric vehicle power battery frame lifting device, comprising a lifting frame 1, a lifting mechanism 2 is connected to the lower end of the lifting frame 1, a battery frame 4 is fixedly connected to the bottom inner wall of the lifting frame 1 through a shock absorbing mechanism 3, and the battery frame 4 is installed There is a battery body 5, the upper outer wall of the battery body 5 is symmetrically fixedly connected with two fixed plates 6, the outer wall of the battery frame 4 is fixedly connected with a fixed block 7 corresponding to the fixed plate 6, and the fixed plate 6 and the fixed block 7 pass through a limit Bit mechanism 8 connections;

[0035] Lifting mechanism 2 comprises support box 21, and the inner wall of support box 21 left and right opposite sides is connected with two rotating rods 22 symmetrically rotating back and forth through ball bearings, and the rod wall of rotating rod 22 is fixedly sleeved with two active helical ...

Embodiment 2

[0045] see Figure 5-Figure 6 A lifting device and a lifting method for a power battery frame of an electric vehicle are arranged in a power management system, and a control chip of the power management system controls a driving motor 25 in the lifting device through a circuit connection.

[0046] The power management system also includes: a temperature detection board located at the bottom of the battery frame 4, and a heat dissipation device arranged on the inner side of the battery frame 4; The internal circulating air duct 13 is introduced by the cooling device to exchange the air inside and outside the battery frame 4, and the high-temperature air in the battery body 5 is exported to the battery frame 4 through the cooling fan 12, and the external air introduced first enters the circulating air duct 13 A spiral coil 14 is installed in the circulating air duct 13, and water at a constant temperature is provided inside the spiral coil 14. After the air passes through the sp...

Embodiment 3

[0049] It also includes a heat-conducting tube sleeved in the shock-absorbing rubber ring, and the heat-conducting tube communicates with the spiral coil 14 to form a temperature control path. When the temperature is higher than the predetermined temperature, such as in summer, the rubber ring is cooled by the temperature control device, and at the same time, the heat around the battery is absorbed to prevent the rubber ring from being oxidized and invalidated due to excessive temperature. When the temperature is lower than the predetermined temperature, the rubber ring is kept warm by the temperature control device to prevent the rubber ring from becoming brittle and losing the shock absorption effect when it is cold.

Abstract

The invention relates to the technical field of automobiles, and discloses an electric automobile power battery frame lifting device and a lifting method. A lifting frame is included. The lower end ofthe lifting frame is connected with a lifting mechanism. The inner wall of the bottom of the lifting frame is fixedly connected with a battery frame through a damping mechanism. A battery body is arranged in the battery frame. Two fixing plates are symmetrically and fixedly connected to the outer wall of the upper end of the battery body, and the outer wall of the battery frame is fixedly connected with fixing blocks corresponding to the fixing plates. The fixing plates and the fixing blocks are connected through limiting mechanisms. The electric automobile power battery frame lifting devicehas the advantages that the relative height of the battery frame can be rapidly and conveniently adjusted, battery replacement is convenient, and heightening of an automobile chassis cannot be caused.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a lifting device and a lifting method for a power battery frame of an electric vehicle. Background technique [0002] New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, and other new energy vehicles. There is no economic scale, so the purchase price is more expensive. Electric vehicles can also make full use of the surplus electricity when the electricity consumption is low at night to charge, so that the power generation equipment can be fully utilized day and night, greatly improving its economic benefits. Relevant studies have shown that the same crude oil is crudely refined, sent to a power plant to generate electricity, charged into a battery, and then powered by a battery to drive a car. and reduce carbon dioxide emissions. [0003] At present, the two power batt...
