Embodiment Construction

[0029] A compact electronic parking mechanism, see figure 1 , figure 2 , which includes ratchet 1, pawl 2, cam 3, spring leaf 4, rail plate assembly 5, main shaft 6, return spring assembly 7,

[0030] The ratchet 1 includes a plurality of ring cloth locking grooves 101, which are used to control the locking and unlocking of the gearbox;

[0031] The pawl 2 includes a pawl protrusion 21 and a driving end 22;

[0032] The cam 3 drives the pawl protrusion 21 to enter the locking groove 101 of the ratchet 1;

[0033] The spring leaf 4 includes a locking pressure attachment rod 41 and a guide pressure attachment end 42. During specific implementation, the guide pressure attachment end 42 of the spring leaf 4 is fixed at the corresponding position of the car body, and the locking pressure attachment rod 41 performs a deformation action;

[0034] The outer periphery of the rail plate assembly 5 is provided with a number of protruding stop teeth 51, and the adjacent protruding sto...

Abstract

The invention provides a compact electronic parking mechanism which is compact in structure and convenient to install, reduces parking torque and reduces impacts on a push rod assembly and a rail plate assembly during unlocking. The compact electronic parking mechanism comprises a ratchet wheel, a pawl, a cam, a spring piece, the rail plate assembly, a main rotating shaft and a return spring assembly. The ratchet wheel comprises a plurality of locking grooves which are annularly distributed and are used for controlling locking and unlocking of a gearbox. The pawl comprises a pawl protruding part and a driving end. The cam drives the pawl protruding part to enter the locking groove of the ratchet wheel. The spring piece comprises a locking pressing and attaching rod and a guiding pressing and attaching end. A plurality of protruding limiting teeth are arranged on the periphery of the rail plate assembly, and gear grooves are formed in the adjacent protruding limiting teeth. The locking pressing and attaching rod is arranged towards the gear grooves and presses and is attached to the corresponding gear grooves under the deformation of the spring piece. The main rotating shaft is externally connected with a power rotating part, the output end of the main rotating shaft is fixedly sleeved with the rail plate assembly, and the plane where protruding limiting teeth of the rail plate assembly are located is perpendicular to the main rotating shaft.

Description

technical field [0001] The invention relates to the technical field of parking mechanisms, in particular to a compact electronic parking mechanism. Background technique [0002] With the development of automobile technology, people pay more and more attention to vehicle safety. The P gear parking system can lock the vehicle when the vehicle stops or when the speed is low, preventing the vehicle from slipping on a slope and causing safety hazards. accidents and improve safety performance. The parking mechanism is a safety device to prevent the vehicle from slipping. It can make the car park at a certain position reliably and without time limit. The advantage is very obvious. Therefore, the number of vehicles equipped with the P-gear parking system is gradually increasing, the application is becoming more and more extensive, and more and more researches have been invested. [0003] Electronic parking mechanism is the development trend of the current market. The mechanism of ...
