[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The manual release device for an electric vehicle after parking is provided with a mounting frame, a switch button, a support plate, a drive motor, a front stabilizer bar, a handbrake cable body, a mounting frame, a handle, a damping shaft, a mounting column, a first gear, a second gear, a rack plate, a limit block, a connecting block, a telescopic column, a mounting cylinder and a contact ring. When in use, when the vehicle needs to be parked, the handle is held and the handle is rotated counterclockwise, and the handle drives the damping shaft, the mounting column and the first gear to rotate at the same time, and then the first gear is meshed with the second gear. When the first gear rotates, the handbrake cable body is pulled, so that the vehicle starts to park, and then the second gear is rotated clockwise. At this time, the second gear drives the rack plate to move to the left, and then the rack plate can be limited by the design of the limit block, and then the telescopic column is driven to move inside the mounting cylinder by the rack plate, and then the telescopic column pushes the contact ring, and then the contact ring The spring body is squeezed, and the connecting column is inserted into the inside of the groove. Then the left surface of the resistance ring will resist the right surface of the resistance ring, so that the resistance ring will apply pressure to the pressure ring. The pressure ring can sense the pressure and transmit a signal to the switch button, so that the switch button can turn off the power of the drive motor, so that the entire vehicle cannot be driven. At this time, the vehicle can successfully complete the parking operation through the cooperation of the drive motor and the handbrake cable body. When the operation needs to be released, the handle is restored to its original position by holding the handle. At this time, the handbrake cable body begins to loosen, and then the rack plate will move to the right, and then the rack plate will drive the side block and the pressure block to move to the right, and then the pressure block will enter the inside of the pressure frame. After the pressure block applies pressure to the pressure frame, the pressure frame will feel the pressure and then transmit a signal to the switch button to turn on the power of the switch button, so that the overall contact parking operation effect is better, and the overall use is relatively safe, which reflects the functionality of the design.

[0019] 2. The manual release device for the electric vehicle after parking is provided with a top block, a stabilizing plate, a limiting roller, a mounting block, an installation wire, a limiting frame, a fixing frame, a positioning frame, a lower pressure plate and a heat-conducting frame. When in use, the limiting roller is limited by the design of the top block and the stabilizing plate, and the position of the handbrake cable body can be limited by the limiting roller to avoid the handbrake cable body from being entangled during use, which affects subsequent use. Then, the installation wire can be limited by the design of the limiting frame to ensure that the overall installation wire has a limiting effect during installation. The position of the limiting frame can be limited and fixed by the fixing frame, and the overall fixing effect is good. Subsequently, the heat-conducting frame is fitted with the outer surface of the drive motor to absorb and transfer the heat emitted by the drive motor, thereby eliminating the heat emitted by the drive motor as a whole. At the same time, the stability of the heat-conducting frame can be enhanced by the positioning frame and the lower pressure plate, which reflects the ingenuity of the design.
