Parking lock with double torsion spring balancing device

Abstract

The invention relates to a parking lock with a double torsion spring balancing device. Compared with an existing remote parking lock in the market at present, double torsion springs are adopted by the parking lock; when the parking lock with the double torsion spring balancing device is locked, a driving gear drives a driven gear to rotate, so that a drive shaft drives the rotating shaft to reversely rotate. The rotating shaft rotates and further drives a retaining wall to rotate to a vertical position from a horizontal position. In the process, a pressure-bearing end of each torsion spring has elasticity generated to restore elastic deformation due to gravity of the retaining wall, so that a drive device can lift the retaining wall by providing relatively low power, so that the power consumption of the drive device is greatly reduced and the service life of a power supply device is prolonged. When the retaining wall is vertical to the ground, if the retaining wall is pushed by external force, the drive device can restore the retaining wall into the vertical state by using relatively low power consumption due to the actions of the double torsion springs no matter which side the external force faces.

Description

technical field [0001] The invention relates to the technical field of remote control parking locks, in particular to a parking lock with a double torsion spring balancing device. Background technique [0002] With the continuous increase of car ownership, parking spaces have become a scarce resource. Therefore, there are some special parking spaces in the existing parking lots. In order to prevent the special parking spaces from being occupied, the owners or management units of the parking spaces will Parking berth locks are set on special parking spaces. For the convenience of drivers, existing berth locks have begun to adopt remote control berth locks. [0003] The remote control parking lock is an intelligent mechanical device. Its function is to prevent others from occupying your own parking space. Your own car can be parked at any time through the remote control, and it is not like a physical lock that you have to get out of the car to unlock and lock. [0004] On Mar...

AI Technical Summary

Problems solved by technology

[0006] 1. The speed of the worm wheel and the worm is relatively large, and the worm needs to rotate enough times to rotate to the required angle. In order to reduce the transmission time, the motor needs to rotate at high speed through the transmission shaft to drive the worm to rotate at high speed, so the motor consumes a lot of power. Use higher cost;

[0007] 2. The high rotational speed of the worm also requires the worm to have good wear resistance and to be lubricated frequently, and the maintenance cost is high;

[0008] 3. Due to the reverse locking function of the worm gear and worm, in the actual use of the remote control parking lock, the blocking arm will be hit or pressed, and the worm gear will generate a large locking force, which makes the worm gear mechanism easy to be damaged. Destruction, higher requirements on the strength of the turbine and worm, and higher manufacturing costs of the turbine and worm

If the anti-collision device of this parking lock needs to realize the two-way anti-collision function, two sets of devices need to be arranged on the main shaft, and its structure is relatively complicated, and the manufacturing cost is relatively high.
