Detailed description of the invention
With reference to the accompanying drawing the utility model is made further to describe and illustrate.
Fig. 1 is the schematic diagram of the automotive safety hand brake system of the utility model first choice embodiment.
Specific embodiment
Below in conjunction with attached drawing, by the description to preferred embodiments of the present invention, more clearly and completely explain
State the technical solution of the utility model.
As shown in Figure 1, the automotive safety hand brake system of the utility model first choice embodiment includes seat portion 1, parking brake
Part 2, safety hand braking pull string 3, parking brake tripper 4.
Seat portion 1 includes seat 11, seat shaft 12, tension spring 13.
Seat 11 is installed in rotation on automobile by seat shaft 12.The bottom of seat 11 is arranged in tension spring 13
Portion, and it is located at the intermediate position of seat bottom.
Tension spring 13 applies a upward spring force to seat 11, so that seat 11 has the tendency that being rotated up,
Under the action of not having external force, seat 11 is in upper lift position (i.e. shown position) under the action of tension spring 13.Work as driver
When being sitting on seat 11, so that tension spring 13 compresses, seat 11 arrives rotationally clockwise along diagram for the self weight of driver
Seat bottom is in a horizontal position.
Seat portion 1 includes also position-limit mechanism (not shown), for limiting the upper lift position of seat 11.Preferably,
When seat 11 is in upper lift position, angle is 10 °~15 ° between seat bottom and horizontal line.In view of the weight of driver,
The elastic force of tension spring 13 is at least 80kg.
Parking brake part 2 includes hand brake lever 21, manual brake button 22, the rotating disk 23 with shaft, ratchet 24, pawl 25, steel
Silk bracing wire 26, brake 27.
Hand brake lever 21 is fixedly connected with rotating disk 23, and hand brake lever 21 rotates upwardly and downwardly the forward and reverse rotation that will drive rotating disk 23
Turn.The first end of steel wire pull line 26 is fixed in rotating disk 23, and second end is fixedly connected with brake 27.
Manual brake button 22 is arranged in the end of hand brake lever 21, and is mechanically connected with pawl 25, for discharge pawl 25 with
The engagement of ratchet 24.
Safety hand braking pull string 3 is arranged between seat portion 1 and parking brake part 2, and connects the two parts, so that seat
Interaction relation is generated between part 1 and parking brake part 2, realizes safe parking brake function.Specifically, one end of safety hand braking pull string 3
It is connect with tension spring 12, the other end is connect with the first end of steel wire pull line 26.In other embodiments, safety hand braking pull string
3 can also connect with rotating disk 23.
Parking brake tripper 4 includes steel wire 41 and spring 42.Spring 42 is arranged below hand brake lever 21.At spring 42
When original state, the upper end of spring 42 is contacted with hand brake lever 21, and when spring 42 is compressed, hand brake lever 21 is left in the upper end.
One end of steel wire 41 is connected to below 11 front end of seat, and the other end is connect with the upper end of spring 42.
When driver is not sitting on seat 11, automobile is in dead ship condition, when seat 11 is located at upper lift position, spring 42
In initial position, hand brake lever 21 is resisted upwards, and hand brake lever 21 is the state being pulled up；When driver is sitting on seat 11, seat
Chair 11 turns to horizontal position, and steel wire 41 drives spring 42 to compress downwards, and hand brake lever 21, hand brake lever 21 are left in the upper end of spring 42
It is released, driver can push hand brake lever 21 and start-up a car.
Automotive safety hand brake system also includes a seat locking device, for seat to be locked in horizontal position.The seat
Chair locking device is arranged between safety belt lock catch and seat, and specifically, one end of seat locking device and safety belt lock catch connect
It connects, the tension spring 13 of the other end and under-seat connects.When driver takes seat 11 and fastens one's safety belt, seat locking
Tension spring 13 is locked in compressive state by device, does not apply upward power to seat 11, and design is so that driver is sitting in this way
When adjusting sitting posture on seat or raising oneself slightly, tension spring 13 will not lift seat 11, so that safe parking brake be driven to move to system
Dynamic position also ensures the comfort of the seat of driver on the seat.Only when driver unlocks safety belt, seat locking dress
It sets and just discharges tension spring 13, restore the function of safe parking brake.In other embodiments, the other end of seat locking device
It can act on seat 11, when safety belt is fastened, seat 11 is locked in horizontal position, Wu Fashang by seat locking device
Lift, the program can equally play the role of locking seat.
The working principle of above-mentioned automotive safety automatic hand brake system is as follows:
When driver, which takes seat 11, prepares driving, the self weight of driver pushes seat 11, so that seat 11 is around seat
Rotationally clockwise along diagram, spring 42 compresses shaft 12, and hand brake lever 21 is released, while tension spring 13 compresses, peace
Tensioning between full parking brake bracing wire 3 and steel wire pull line 26 is released.At this point, parking brake part 2 plays traditional parking brake effect.
In driving procedure, when driver is to be stopped, driver should pull-up parking brake, by pulling up hand brake lever
21, hand brake lever 21 drives rotating disk 23 to be pivoted, and rotating disk 23 drives steel wire pull line 22 to be pulled along, so that braking be driven
Power passes to brake 21.Brake 21 is drum brake, is generated using the engagement of shoe plate and friction plate in brake rim
Brake force, so that automobile be made to remain stationary.When automobile brake in place after, the pawl 24 connecting with hand brake lever 21 is stuck in ratchet 25
On, prevent 21 return of hand brake lever.
When driver is intended to continue when driving, to need to unclamp parking brake, driver holds hand brake lever 26, first presses parking brake with thumb
Then button 27 rotates hand brake lever 26 so that pawl 24 is disengaged with ratchet 25 still further below, hand brake lever 26 drives rotating disk 23
It reversely rotates, steel wire pull line 22 is walked backward, brake force of the release action on brake 21.
When driver is stopped and leaves the non-pull-up parking brake of seat 11, spring 42 restores to original state, stretches upwards,
Hand brake lever 21 is jacked up to extended position, while the compression of tension spring 13 is released and extends, seat 11 is in tension bullet
It is bounced under the action of spring 13, along rotating counterclockwise for diagram.The stretching, extension of tension spring 13 tenses safety hand braking pull string 3,
Safety hand braking pull string 3 pulls steel wire pull line 26 again, and brake force is passed to brake 27 by steel wire pull line 26, and brake 27 generates system
Power, hand brake lever 21 have been automatically pulled, and remain stationary automobile, and car slipping phenomenon will not occur.
The automotive safety hand brake system of the utility model will form interaction relation between seat portion and parking brake part, pass through
Lifting for seat drives parking brake part to work, accordingly even when driver forgets to pull the hand brake, car slipping phenomenon will not occur.The vapour
The safe hand brake system of vehicle solve the problems, such as in the prior art as parking when do not pull the hand brake and caused by car slipping, improve vehicle
Safety, structure is simple, cost is relatively low, easy to accomplish.
Above-mentioned specific embodiment is only described preferred embodiments of the present invention, and not practical to this
Novel protection scope is defined.Under the premise of not departing from the utility model design conception and scope, this field
Those of ordinary skill is according to verbal description provided by the utility model, attached drawing to made by the technical solution of the utility model
Various modifications, substitution and improvement should belong to the protection category of the utility model.The protection scope of the utility model is wanted by right
Ask determining.
