Description

High-strength vehicle seat angle adjustor core members with rolling structure

Technical field

The utility model relates to angle regulating device for seat of vehicle technical fields, and in particular to a kind of high intensity with rolling structure Angle regulating device for seat of vehicle core members.

Background technique

Angle regulating device for seat of vehicle is more comfortably to multiply for adjusting back angle to obtain for driver or occupant The component of vehicle environment.Currently, there are many type of angle regulating device for seat of vehicle both at home and abroad.Wherein built-in round automotive seat angle modulation Favor of device due to its is small in size, compact-sized by vast automobile vendor.

The built-in round angle regulating device for seat of vehicle of the prior art, including shell, the circular tooth disk with internal tooth, disk Seat, driving structure, are equipped with tooth plate in disc seat, outside tooth plate end i.e. opposite with circular tooth disk be equipped with have in circular tooth disk The end of the external tooth of tooth cooperation, the internal tooth for the separate circular tooth disk that tooth plate inside cooperates with driving structure is equipped with allocating slot, disc seat It is interior to be equipped with for tooth plate merging and for the accommodation groove that tooth plate is moved radially along disc seat, it constitutes and is used between circular tooth disk and disc seat The inner cavity of driving structure is accommodated, driving structure includes drive shaft, disc spring, latch segment, and the outer wall of latch segment is equipped with to be cooperated with allocating slot Pusher dog, drive shaft turns drive latch segment when rotating in one direction, and the pusher dog of latch segment drives the tooth plate edge with allocating slot Circular tooth disk is moved radially outward, and is locked after the internal tooth cooperation of the external tooth and circular tooth disk of tooth plate, tooth plate and circular tooth disk limit drive Axis and circular tooth disk limit, and when drive shaft turns drive latch segment to rotate towards another opposite direction, the pusher dog of latch segment drives tool There is the tooth plate of allocating slot to move radially inwardly along circular tooth disk, the external tooth of tooth plate and the internal tooth of circular tooth disk are detached from and unlock, tooth plate and circle Fluted disc does not limit i.e. drive shaft and does not limit with circular tooth disk.

In the prior art, multiple protrusions only are set to reduce between circular tooth disk and shell towards circular tooth disk in cavity bottom surface Friction, the friction reduction effect of this structure is still not good enough, and shell is still easy stuck with circular tooth disk；Also or in shell cavity Rolling structure is set on the outer peripheral surface of side wall and knuckle-tooth, which can make the concentricity of shell and circular tooth disk be deteriorated, and then cause It is stuck between shell and circular tooth disk.

Summary of the invention

The technical problem to be solved by the utility model is to provide relative motion effect between a kind of shell and circular tooth disk is good High-strength vehicle seat angle adjustor core members with rolling structure.

A kind of the technical scheme in the invention for solving the above technical problem are as follows: high-strength vehicle with rolling structure Seat angle adjustor core members, including circular tooth disk, shell, are equipped with the cavity of accommodating circular tooth disk in the shell, knuckle-tooth side surface with Being equipped between cavity bottom surface makes circular tooth disk and shell roll the rolling structure of cooperation.

Compared with the prior art, the advantages of the utility model are: being set between the end face of circular tooth disk and the bottom surface of cavity Rolling structure is set, two kinds of designs compared to the prior art, rolling effect is good, and does not influence circular tooth disk and cavity in rolling process In concentricity, avoid circular tooth disk and cavity stuck.

As a kind of also improvement of the utility model, the rolling structure includes retainer, rolling member, the rolling member Be it is multiple and along the circumferentially-spaced arrangement of retainer, the retaining hole being placed in for rolling member is equipped in the retainer, is changed by described Into simultaneously the first embodiment that rolling member is rolling structure is arranged in setting retainer in retainer, to reduce shell and knuckle-tooth Friction between disk improves shell movable flexibility ratio opposite with circular tooth disk, and rolling structure is arranged in the end face of circular tooth disk It will not influence the alignment of circular tooth disk and shell when circular tooth disk and shell relatively rotate with the basal surface position of cavity, avoid justifying Fluted disc is blocked with shell.

As a kind of also improvement of the utility model, the rolling structure includes the multiple accommodatings being located on cavity bottom surface Hole and the rolling member for being located in accommodating hole and cooperating with accommodating hole are arranged accommodating hole and are simultaneously set in accommodating hole by the improvement Second of embodiment that rolling member is rolling structure is set, this kind of structure can reduce the processing and setting of retainer, reduce manufacture Cost and assembly cost, and this rolling structure equally can reduce the friction between shell and circular tooth disk, improve shell and circle The relatively movable flexibility ratio of fluted disc, and rolling structure is arranged in the end face of circular tooth disk and the basal surface position of cavity, in circular tooth disk When being relatively rotated with shell, it will not influence the alignment of circular tooth disk and shell, circular tooth disk avoided to block with shell.

As the utility model there are also a kind of improvement, the rolling structure includes the annular groove being located on cavity bottom surface and sets Multiple rolling members in annular groove, by the improvement, this kind of structure is the third embodiment of rolling structure, when shell and circle Power between fluted disc it is larger and reduce the requirement of friction it is relatively high when, annular groove can be set on the shell, full or root is set in annular groove According to demand, rolling member is set.

As the utility model there are also a kind of improvement, the rolling member is ball or roller, passes through the improvement, rolling Moving part can according to need selection ball either roller.

As the utility model there are also a kind of improvement, the number of the rolling member is 3~300, by the improvement, Need to select the number of rolling member appropriate according to the size of core members and rolling.
