Description

Technical Field

[0001] The utility model relates to the technical field of vehicle parking brakes, in particular to a push-pull type parking operating mechanism with an adjustable lever ratio. Background Art

[0002] At present, the parking brakes of conventional vehicles on the market basically adopt the handle rotation and pull-up type. For the convenience of operation, they are basically placed on the left and right of the main driver's seat of the vehicle, occupying the driving and riding space, and the lever ratio of the mechanism is fixed and cannot be changed, and the parking control force is fixed.

[0003] Therefore, a push-pull parking control mechanism with adjustable lever ratio is proposed. Summary of the invention

[0004] The utility model aims to provide a push-pull parking control mechanism with adjustable lever ratio to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A push-pull parking control mechanism with adjustable lever ratio, comprising a push-pull handle and a mounting support, wherein the mounting support is provided with a cable rocker arm, one end of the push-pull handle is provided with a push-pull operating rod, the rod body of the push-pull operating rod is provided with an operating rod guide sleeve matched therewith, and the operating rod guide sleeve is installed on the mounting support;

[0007] A joystick gear limiting paddle is provided at the connection between the mounting support and the guide sleeve;

[0008] A joystick connecting fork is provided at one end of the push-pull joystick, and the joystick connecting fork is connected to the wire-pulling rocker arm;

[0009] The wire-pulling rocker arm is provided with a wire-pulling connection fork.

[0010] Furthermore, the mounting support is provided with a parking switch bracket.

[0011] Furthermore, the mounting bracket is fixed to the vehicle body through the mounting hole.

[0012] Furthermore, the push-pull operating rod passes through the operating rod guide sleeve and is connected to the operating rod connecting fork through a fixed pin shaft.

[0013] Furthermore, the joystick guide sleeve is fixed to the mounting support via a pin shaft and a locking pin.

[0014] Furthermore, the operating lever shifting gear limiting shifting piece is fixed to the mounting support through a pin shaft and a locking pin.

[0015] Furthermore, the joystick connecting fork is connected to the cable rocker arm through a pin shaft and a locking pin.

[0016] Furthermore, the cable connection fork is connected to the cable rocker arm through a pin shaft and a locking pin.

[0017] Furthermore, the wire pulling rocker arm is connected to the mounting support via a pin shaft and a locking pin, and the mounting support is provided with a torsion spring for resetting.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] The push-pull operation type can be arranged in front of the driver. Compared with the traditional rotary pull-up handbrake, it releases the left and right space of the main driver, and the driver's left and right operation space becomes larger; by adjusting the position of the pull rod rotation axis, the mechanism leverage ratio can be changed, and the operating force can be adjusted to meet the different operating force needs of different drivers, thereby improving the selectivity of product function expansion. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Figure 2 It is a schematic diagram of the top structure of the utility model. DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] Embodiment 1:

[0024] See also Figure 1-2 , the utility model provides a technical solution:

[0025] A push-pull parking control mechanism with an adjustable lever ratio, wherein a push-pull handle 1 and a push-pull operating rod 2 are fixed together by threads, the push-pull operating rod 2 passes through a guide sleeve and is connected to an operating rod connecting fork 5 by a fixed pin shaft, the operating rod guide sleeve 3 is fixed to a mounting support 9 by a pin shaft and a locking pin, the operating rod shifting tooth limit paddle 4 is fixed to the mounting support 9 by a pin shaft and a locking pin, the lower paddle is returned by a torsion spring, the operating rod connecting fork 5 is assembled with a cable rocker arm 6 by a pin shaft and a locking pin, the cable connecting fork 7 is assembled with the cable rocker arm 6 by a pin shaft and a locking pin, the cable rocker arm 6 is assembled on the mounting support 9 by a pin shaft and a locking pin, and is returned by a torsion spring 16, and the mounting support 9 is fixed to the vehicle body by three mounting holes.

[0026] Working principle:

[0027] The driver controls the push-pull handle 1 to move forward and backward along the joystick guide sleeve 3 to pull the cable rocker arm 6 to move, and actuates the cable connection fork 7 to pull the cable to achieve parking;

[0028] When the operating force needs to be increased or decreased, the operating force arm is increased or decreased by changing the installation hole position of the operating lever connecting fork 5 and the cable rocker arm 6, thereby realizing the change of the mechanism lever ratio and meeting the expansion function of parking force adjustment.
