Problems solved by technology
However, the parking motor has a high speed and low torque, which cannot meet the low speed and high torque requirements of the parking system.
At present, some companies use the integrated worm gear mechanism or integrated planetary gear mechanism on the motor for deceleration and torque increase. Due to the addition of the deceleration mechanism, the structure of the motor itself needs to be redesigned, which increases the development and production costs of the motor, especially the motor. The protection level of the electric vehicle is reduced due to the complexity of the structure, which increases the safety hazard of electric vehicles

Embodiment Construction
[0032] In order to describe the technical content of the present invention more clearly, further description will be given below in conjunction with specific embodiments.
[0033] Such as figure 1 Shown is a schematic structural diagram of the parking system for electric vehicles in the first embodiment of the present invention when it is unlocked.
[0034] In order to improve the safety performance of electric vehicles, especially pure electric vehicles, an electric parking system has been invented, wherein the parking system includes a ratchet 1, a pawl 2, a drive shaft 3, a first drive plate 41, and a second drive plate 42, driving plate pin 43, driving plate pin 44, stage clip 5, pressing plate 6, limit mechanism 62, driving plate connection block 7, return spring 90, drive shaft bearing 92, screw transmission pair 100 and parking motor 200.
[0035] The drive shaft 3 and the pressing plate 6 have a screw transmission pair 100 that cooperates, and the screw transmission p...

The invention relates to a parking system for an electric vehicle. The parking system for the electric vehicle comprises a drive motor, a drive shaft, a rotating movement conversion part, a first drive plate and a ratchet mechanism; the drive shaft rotates along with the rotation of the drive motor; the rotating movement conversion part is used for converting the rotating movement of the drive shaft into the linear movement along the axial direction of the drive shaft; the first end of the first drive plate is rotatably connected with the rotating movement conversion part; and the second end of the first drive plate is connected with the pawl of the ratchet mechanism. By the adoption of the parking system with the structure, the electric vehicle can be parked and unlocked safely; the safety performance of the overall vehicle is improved; a parking motor is an independent structure, so that the model of the parking motor is not limited by the structure any longer; the possibility that the pawl is disengaged because the parking is not in place or the unlocking is not in place is eliminated; and the parking system is simple in structure and convenient to install and has a wide application range.
Description
technical field [0001] The invention relates to the field of vehicle transmission, in particular to the field of car parking, in particular to a parking system for electric cars. Background technique [0002] With the application of electric vehicles more and more widely, the safety performance requirements of electric vehicles are getting higher and higher. At present, most electric vehicles do not have a parking system, which cannot meet the safety performance requirements of electric vehicles. However, the parking system on conventional fuel vehicles cannot be directly applied to electric vehicles due to different control methods and a very complicated mechanical structure. [0003] In order to facilitate control, the electric vehicle parking system is directly driven by the parking motor. However, the parking motor has high speed and low torque, which cannot meet the low speed and high torque requirements of the parking system. At present, some companies use the integ...
