Embodiment Construction

[0013] The invention provides a supporting device for a battery pack of an electric vehicle. Further description will be given below in conjunction with the accompanying drawings.

[0014] figure 1 Shown is a schematic diagram of the structure of the supporting device. In the figure, the battery pack 1 is connected to the vehicle frame 4 through four sets of parallel springs 2 and dampers 3 to reduce the shock and vibration transmitted to the battery pack 1 during the operation of the vehicle, thereby improving The stressed condition of the battery pack 1 improves the service life. The spring stiffness of spring 2 can be calculated and selected according to the following formula:

[0015] C S = P f = Gd 4 8 D m 3 i...

Abstract

The invention discloses a supporting device for a battery pack of an electric automobile, belonging to the electric automobile manufacturing technical field. The battery pack of the supporting device is connected to a frame through four sets of parallelly connected springs and dampers, wherein the dampers are used for damping vibration. The purpose of using a rubber type or dual-action cylinder type shock absorber battery pack to be connected with the frame through the springs and the dampers, instead of adopting a bolt fixing type to implement hard connection, is to reduce the impact and the vibration which are transferred to the battery pack when the automobile is in motion, so that the load-carrying situation of the battery pack is improved, and the service life is prolonged.

Description

technical field [0001] The invention belongs to the technical scope of design and manufacture of electric vehicles, and in particular relates to a supporting device for battery packs of electric vehicles. Background technique [0002] At present, the research and development of electric vehicles focus on the integration and control of the power system, as well as the development of key components of the power system, and the problem of vibration has not yet been paid attention to. The vibration generated when the vehicle is running will have a direct impact on the battery connection, plate fixing, and electrolyte flow, causing damage to the battery and motor, thereby affecting battery life and safety performance. If the shock resistance and vibration strength of the series-parallel battery connection structure design is not enough, the battery pack is prone to performance fluctuations and attenuation under long-term complex use conditions, and even serious accidents such as ...
