Description
Technical field
The present invention relates to the holding brake devices and motor vehicle of a kind of mobility vehicle.
Background technique
The holding brake device of motor vehicle refers to the hand-operated brake of motor vehicles installation, abbreviation parking brake, after vehicle comes to a complete stop
For stablizing vehicle, avoid vehicle in slope pavement parking since car slipping causes the accident.Common parking brake is typically disposed in driving
Member's right hand pendant position, is easy to use.
The holding brake device of traditional motor vehicle is set to the middle position or installation of front-seat two seats in automobile
In on console.Referring to Figure 1, the holding brake device of motor vehicle shown in FIG. 1 is installed on console, including braking parts with
And for operating brake operating portion whether braking parts are braked, the braking parts are set to the accommodating cavity of interior corresponding position
Interior, the lower end in the brake operating portion is connect to cooperate with braking parts and brake with the braking parts, and upper end is from accommodating top of chamber
Via hole on panel is pierced by expose to panel；The braking parts include the third lock piece 10 with brake operating portion cooperation
An and brake component 12；The brake operating portion include one with the brake component 12 braking cooperation motion arm 20, can be with institute
State the 4th lock piece 22 of 10 locking of third lock piece cooperation and for driving the 4th lock piece 22 and the first lock piece locking
The actuator 24 of cooperation.
The accommodating cavity having inside platform for accommodating 20 lower section of brake portion and motion arm, accommodating cavity top are specifically controlled in the car
The panel in portion is then central control panel, and the via hole being pierced by for motion arm 20 is equipped on central control panel.
Motion arm 20 includes third operating stick 201 and the 4th operating stick 202 connecting with 201 bending of third operating stick, the
The lower end of three operating sticks 201 and the brake component 12 of preparing department connect.It is worn from the via hole of central control panel the upper end of third operating stick 201
Out and expose to central control panel.The lower end of 4th operating stick 202 and the upper end of third operating stick 201, which are bent, to be connected, they can one
Body forming.In the prior art, third operating stick 201 and the 4th operating stick 202 are straight-bar, and whole is in bending, therefore, it is necessary to
Sufficiently large via hole is opened up on panel, is detached from the 4th lock piece 22 in third lock piece 10, then again in braking Shi Caineng
Lifting motion arm 20 is braked.Biggish via hole need the covering (such as utilizing leather and fur products etc.) of enough large area come
The via hole is covered, cost is increased；Biggish via hole needs the panel of enough large area to support, and increases design area, interior
Structural compactness is lower, is not able to satisfy requirement of the user to interior topology layout compactedness, reduces user satisfaction.
In addition, actuator 24 in the prior art directlys adopt mechanical driven, i.e. actuator 24 includes length and motion arm
20 match third push rod 241, third push rod 241 upper end button 242 is installed, the 4th lock piece 22 passes through the 4th rotation
Axis is installed on the lower end of third push rod 241 and can rotate around the 4th rotary shaft.
Braking principle is as follows: when needing to brake, by lower button 242, button 242 push mechanical third push rod 241 so that
4th lock piece 22 of mechanical 241 lower end of third push rod is detached from third lock piece 10, while pulling the 4th operating stick 202 upwards
To drive the drag-line of brake portion, so that brake-shoe be made to be pressed on wheel hub, key is then unclamped, the 4th lock piece 22 is stuck at this time
Braking is realized in corresponding position on third lock piece 10.It is equally pressed the button when releasing braking, key pushes third push rod 241
It pushes latch to be detached from castellated plates, pulls operation handle and return to home position, drive drag-line that brake-shoe is detached from wheel hub, braking solution
It removes.By the way of mechanical driven, have the disadvantage that each component of actuator 24 is all made of mechanical connection, with using
The problems such as time is continuously increased, may be due to aging, service life between mechanical parts causes especially third at each machinery
, there are the problems such as abnormal sound etc. in Caton between cooperation between push rod 241, third push rod 241 and the 4th lock piece 22, causes to push not
Flexibly, and then the cooperation between the 4th lock piece 22 and third lock piece 10 is led to problems such as Caton occur, is needed more when serious
Change entire actuator 24, motion arm etc..
