Description

Can conveniently aim at quick battery replacement device of electric motor car battery of formula Technical Field The invention relates to the technical field of battery replacement of electric vehicles, in particular to a quick battery replacement device for an electric vehicle, which can be conveniently aligned. Background In the present urban traffic system, the two-wheeled electric vehicle becomes an important choice for short-distance travel of masses of citizens by virtue of the characteristics of flexibility, convenience, economy and environmental protection, however, the battery endurance of the electric vehicle is limited, the charging time is long, the convenience and the efficiency of the use of the electric vehicle are seriously restricted, the battery changing cabinet is generated for effectively solving the problem, the convenience service for quickly changing the full-charge battery is provided for users, and the use experience of the electric vehicle is greatly improved. The current two-wheeled electric motor car battery trades electric cabinet has satisfied user's trading electric demand to a certain extent, take chinese patent with publication number CN119821173a as an example, its structure and function to trading electric cabinet have carried out corresponding improvement, it discloses an electric motor car battery trades electric cabinet, including a plurality of cabinet body, a plurality of cabinet body laminates in proper order, every cabinet body's top all is provided with lifting unit, lifting unit is including the positioning seat that is located cabinet body top, the inner wall rotation of positioning seat is installed and is received the roll, receive and releases the outer wall winding of roll has the connecting band, the one end fixed mounting who receives the roll is kept away from to the connecting band has the lifter, be provided with between two lifters and place the subassembly, a plurality of storehouse that charges has been seted up in the front of the cabinet body, the inboard in storehouse that charges is provided with moving subassembly and charging unit. When the battery is taken out, the battery is moved to the corresponding charging bin through the lifting component, the fully charged battery is pulled out under the action of the moving component, then the battery is controlled to be lowered to the lowest position through the lifting component, and the battery is taken down. However, the above prior art has some drawbacks in the process of rapidly replacing the battery: 1. Above-mentioned prior art is through the inside moisturizing of the mode with battery lift to cabinet body, only keeps the taking and discharging pond mouth of cabinet body bottom, consequently influences the efficiency of changing electricity, especially in the delivery lunch, supper and express delivery waiting in a rush-time such as waiting in a line that needs the takeaway of changing electricity and express delivery person need, leads to changing the electricity time to increase, influences user experience, and promotes out the battery of full electricity and descend to the minimum, leads to the user to need squat down to take, the operation is inconvenient. 2. Although can push the battery into the storehouse that charges through removing the group and trade, but need the user place the battery that will trade down on placing the subassembly, and be difficult to ensure that the user follows the operation instruction of trading the electric cabinet completely and place the battery, lead to the battery to not place in appointed position easily to remove the subassembly and can't push the battery into the storehouse that charges accurately, easily cause the battery to bump or the jamming to take place with the storehouse entry edge that charges because of the angle is slightly off-set in the pushing process, increased the risk of returning failure. Therefore, under the above stated viewpoints, the existing battery changing cabinet for the electric vehicle has room for improvement. Disclosure of Invention In order to solve the problems, the invention provides a quick battery replacing device for an electric vehicle, which can conveniently align to the electric vehicle, and comprises a cabinet body, wherein one side of the cabinet body is provided with a plurality of power supplementing cabins, and a cabin door for closing the power supplementing cabins is arranged in a horizontal manner; The guiding and fixing unit comprises a U-shaped storage rack which is arranged on the inner wall of the electricity supplementing bin in a sliding manner, a charging plug is arranged on the U-shaped storage rack, a main controller and an information processing terminal are arranged in the cabinet body, the main controller and the information processing terminal are connected through an electric signal, a secondary controller is arranged on the U-shaped storage rack, the secondary controller and the main contro
