Battery pack assembly of electric vehicle

Abstract

The invention relates to a battery pack assembly of an electric vehicle, which comprises a battery box (8), a plurality of lithium batteries (1) in the battery box (8), and a handle (3), wherein the lithium batteries (1) are provided with locking devices (5) which comprise slide seats (51), clamping strips (52) in slide fit with the slide seats (51), and elastic devices (53) used for pushing the clamping strips (52) to inwards move; when the handle (3) is lifted, the clamping strips (52) are released and are pushed by the elastic devices (53) to inwards contract, and the lithium batteries are in unlocked state; when the handle (3) is pressed downwards, the clamping strips (52) are pushed and extruded outwards by the handle (3) so that the outer end parts of the clamping strips (52) are extruded out of the slide seats (51) and inserted into locking holes (83) of the inner wall of the battery box (8); and the lithium batteries (1) are locked on the battery box (8). In the battery pack assembly of the electric vehicle of the invention, the lithium batteries and the battery box are positioned firmly and stably; and the charging period is long, which is convenient for quickly replacing well-charged batteries in a charging station and prevents vehicle owners from waiting for a long time.

Description

technical field [0001] The invention relates to a power supply assembly of a vehicle driven by a power source, in particular to a battery pack assembly of a portable electric vehicle, which is especially suitable for electric vehicles such as electric motorcycles, electric bicycles, and electric tricycles. Background technique [0002] Along with the attention of the country and society to environmental protection, the vehicle that uses electric power to drive is just just more and more paid attention to by people because of its advantages such as environmental protection, cleanness, less pollution, also more and more popular. In the prior art, vehicles driven by power sources, especially electric motorcycles, generally have the following problems: 1. The battery is usually directly placed in the mounting seat of the electric vehicle, and the activity space of the battery is limited by the inner wall of the mounting seat, while the mounting seat There is always a certain gap...

AI Technical Summary

Problems solved by technology

In the prior art, vehicles driven by power sources, especially electric motorcycles, generally have the following problems: 1. The battery is usually directly placed in the mounting seat of the electric vehicle, and the activity space of the battery is limited by the inner wall of the mounting seat, while the mounting seat There is always a certain gap between the inner wall of the battery and the outer wall of the battery, so the battery is likely to shake a lot when the vehicle is driving on an uneven road, which will affect the normal operation of the battery

2. Usually, only one set of batteries is used for power supply. The continuous driving mileage of the vehicle is short, and the charging cycle is short. It needs to be charged almost every day, and the charging time is long, so the car mainly waits for a long time; 3. The battery is generally not removable, which is not conducive to Battery replacement and maintenance; 4. Only use one type of battery, such as lead-acid battery or lithium battery, but only using lead-acid battery is not convenient to carry, and only using lithium battery is more expensive

Therefore the battery of existing electric vehicle is very inconvenient to use, has also limited the popularization of electric vehicle greatly
