Problems solved by technology

The battery slot is usually larger than the size of the battery in order to facilitate the placement and removal of the battery, so that the battery will move to a certain extent due to the vibration of the vehicle during driving, and this movement will cause the battery to impact the pole , long-term impact will cause the pole to deform and make poor contact with the battery, or damage the connection between the battery and the pole and make it unusable

Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0016] Such as figure 1 and figure 2 As shown, a quick connection device for a power battery of an electric vehicle in this specific embodiment includes an insulating base 1, two poles 2 pierced on the insulating base 1 along the up and down direction, and two poles 2 for limiting the poles. The pole 2 is a limiting device for displacement travel in the up and down direction on the insulating base 1 , and a gap is provided between the pole 2 and the insulating base 1 .

[0017] In this specific embodiment, the limiting device includes an insulating cover plate 3 sleeved on the pole 2 and screwed to the upper surface of the insulating base 1, the insulating cover plate 3 and the insulating base 1 is provided with an accommodating cavity 4 through which the pole 2 can pass, the upper end and the lower end of the accommodating cavity 4 are respectively provid...

Abstract

The invention discloses a quick connecting device of a power battery for an electric vehicle. The quick connecting device comprises an insulation base, two pole terminals and a limiting device, wherein the two pole terminals are arranged on the insulation base in a penetrating way along the vertical direction; the limiting device is used for limiting the displacement stroke of the pole terminals on the insulation base in the vertical direction; gaps are arranged between the pole terminals and the insulation base. The quick connecting device disclosed by the invention has the advantages that the structure is simple, the connecting is reliable, the damage to the pole terminals is reduced, poor contact of a battery caused by deformation of the pole terminals can be avoided, and the battery protection ability is increased; in addition, the pole terminals can be rotated relative to the insulation base due to the gaps between the pole terminals and the insulation base, so that the friction of connecting positions between the pole terminals and the battery is reduced, and the service life is prolonged.

Description

technical field [0001] The invention relates to a power battery connection device, in particular to a power battery quick connection device for an electric vehicle. Background technique [0002] Electric vehicles use the electric energy stored in the on-board battery as their driving power, but the energy density and power density of power batteries are far inferior to those of gasoline and diesel, resulting in a relatively short mileage of electric vehicles on a single charge, and limited by the characteristics of the battery. It is possible to complete the charging process in a short time. To this end, the way of replacing the battery is used to meet the daily operation needs of the vehicle, that is, when the vehicle is low in power, replace the low battery with a fully charged battery, just like a fuel car refueling at a gas station. Only in this way can electric vehicles Meet people's daily needs. In order to simplify the difficulty of battery replacement, a quick-chan...
