Problems solved by technology

[0003] The existing handbrakes for automobile parking still have certain deficiencies during use. The parking principle of the existing automobile handbrakes is that the user pulls the handbrake lever, thereby driving the parking pawl to deflect through the brake bar. , so that the convex part of the parking pawl is buckled at the groove of the parking ratchet, so as to brake the parking ratchet; wherein, the convex part of the parking pawl and the parking ratchet is relatively opposite to the parking ratchet. The ratchet is relatively small overall. Using the ratchet to pin the ratchet for a long time is essentially equal to the fact that the ratchet is "pulled by the body" by gravity to apply torque to the ratchet in reverse from the transmission structure, which is directly acting on the protrusion of the ratchet. When the protruding part of the pawl is subjected to torque force for a long time, this force will gradually cause the metal fatigue of the protruding part of the pawl, causing internal metal fracture between the protruding part of the pawl and the whole pawl The phenomenon of the pawl will eventually lead to damage to the raised part of the pawl, so that the entire parking device cannot be used normally. Therefore, we propose a new energy vehicle parking structure

Abstract

The invention discloses a new energy automobile parking structure which comprises a driving shell, a first transmission gear, a second transmission gear, a ratchet wheel, a first output gear, a second output gear and a hand brake connecting rod. An input shaft is fixedly mounted on the inner side of the first transmission gear, and the input shaft penetrates the driving shell. Through cooperation of a transmission mechanism and a braking mechanism, in the process that a driver pulls a hand brake, a steel cable drives a rotating pressing piece to rotate through a connecting piece, pressure oil in a first sealing oil barrel and a second sealing oil barrel is adjusted, a ratchet wheel is braked through braking columns, the ratchet wheel is braked through the multiple braking columns arranged in a circumferential array at the same time, the multiple brake columns share the torque force applied by the ratchet wheel together, so that the torque force borne by each brake column is reduced, the service life of the brake columns can be effectively guaranteed, the brake columns are not prone to being damaged, meanwhile, an auxiliary spring-back piece can help the first spring to spring back the sliding block, and the elasticity of a first spring is prevented from being weakened.

Description

technical field [0001] The invention relates to the technical field of parking of new energy vehicles, in particular to a parking structure of new energy vehicles. Background technique [0002] The car parking structure is used to fix the parked vehicle so that the wheels no longer roll. There are usually two parking methods for modern cars, one is electronic handbrake and the other is manual handbrake. If the car needs to be parked for a long time, It is safest to park the car mainly through the manual handbrake; [0003] The existing handbrakes for automobile parking still have certain deficiencies during use. The parking principle of the existing automobile handbrakes is that the user pulls the handbrake lever, thereby driving the parking pawl to deflect through the brake bar. , so that the convex part of the parking pawl is buckled at the groove of the parking ratchet, so as to brake the parking ratchet; wherein, the convex part of the parking pawl and the parking ratch...
