Chassis battery locking mechanism of electric passenger car

Abstract

The invention relates to a chassis battery locking mechanism of an electric passenger car, which is simple in structure, convenient for battery mounting and demounting, easy for production and processing and high in use reliability. The chassis battery locking mechanism of the electric passenger car comprises a mechanical part and an electrical part, wherein the mechanical part comprises a frame; a hook gear and a hook are mounted on a rotating shaft; the rotating shaft is mounted on the frame and at least one axial limiter is arranged at the shaft end of the rotating shaft; a motor is further mounted on the frame; the motor is connected to a motor reducer; the output end of the motor reducer is connected to a motor gear; the motor gear is engaged with the hook gear; the electrical part comprises a position sensor mounted at the lower part of the hook gear; the position sensor is connected to a control panel through a state acquisition board; the control panel is connected to a motor drive module and a power source, and drives the motor to move; and simultaneously, the control panel is further communicated with an input circuit and a display circuit, as well as a vehicle master control station and a background monitoring apparatus, respectively.

Description

technical field [0001] The invention relates to a battery locking mechanism, in particular to a battery locking mechanism for an electric passenger car chassis. Background technique [0002] With the continuous increase of the dual pressure of resources and the environment, in order to alleviate the shortage of oil resources and reduce the pollution of automobile fuel to the environment, the development of new energy vehicles has become one of the future development directions of the automobile industry. In practical applications, due to the limitation of the current battery energy density, the cruising range of electric vehicles is generally between 100 kilometers and 200 kilometers. Whether it can quickly provide energy supply for electric vehicles directly affects the popularization and application of electric vehicles. Normally, it takes several hours to charge the battery slowly, and fast charging will have an impact on the life of the battery, so the research on the b...

Problems solved by technology

[0005] Chinese patent 200910193454.4 proposes a battery installation structure for electric vehicles, but its existing problems are that the mechanism is complex, prone to failure, and the stress condition is not good, and it is easy to deform and fail

[0007] 1. There is no independent control device, and it can only be controlled by the replacement device control system. The unlocking / locking action of the locking mechanism is completed by the battery replacement device. It is necessary to increase the degree of freedom of the replacement device and be equipped with corresponding power and actuators;

[0008] 2. The operation of the locking mechanism can only be monitored and controlled from the replacement device monitoring system, and the status display and operation control of the vehicle center console and on-site status cannot be realized without adding additional devices
