Description

Technical Field

[0001] The utility model relates to the technical field of parking mechanisms, in particular to a parking mechanism of a foot-operated mechanism. Background Technique

[0002] The structure of the parking mechanism is mainly designed according to the layout of the internal space of the gearbox. Generally, it includes parts such as a ratchet wheel, a pawl, a return spring, a taper pin push rod assembly, a pressure guide block, and a rotating toothed plate. When performing a P-gear operation, the taper pin push rod enters between the pressure guide block and the pawl, pressing down the pawl to make the ratchet wheel and pawl teeth mesh, completing the locking action. When exiting the P-gear, the taper pin push rod is withdrawn, and the ratchet wheel and the pawl are disengaged, releasing the P-gear lock.

[0003] Traditional automotive parking brakes usually rely on a hand-operated drive mechanism to generate a braking torque on the rear axle brake or the central brake, and then act on the rear wheels, thereby causing the road surface to generate a braking force on the rear wheels to achieve parking. This method has a fatal problem, that is, due to the different operating forces of the driver, the generated braking torques are also different, which will inevitably reduce the operating safety. Therefore, a parking mechanism of a foot-operated mechanism is proposed to solve the above problems. Content of the Utility Model

[0005] To achieve the above object, the utility model provides the following technical solution: A parking mechanism of a foot-operated mechanism, including an operating handle, a connecting kit is fixedly connected to the left side of the operating handle, an operating rod is rotatably connected to the left side of the connecting kit, a connecting member is rotatably connected to the bottom of the operating rod, a rotating shaft is rotatably connected to the inside of the connecting member, a connecting rod is fixedly connected to the bottom of the connecting member, a ratchet tooth is rotatably connected to the bottom of the connecting rod, a transmission shaft is installed at the bottom of the ratchet tooth, and a ratchet gear is movably connected to the outer surface of the transmission shaft.

[0006] Further, a protective plate is fixedly connected to the outer surface of the operating handle, a same bolt rod passes through the connecting kit and the operating rod, and a fastening nut is threadedly connected to the outer surface of the bolt rod.

[0007] Further, a rotating column is passed through the inside of the connecting member, the bottom of the operating rod is rotatably connected to the connecting member through the rotating column, and the connecting member rotates around the rotating shaft as the axis.

[0008] Further, a compression spring is movably connected between the connecting rod and the ratchet tooth, and the connecting rod is movably connected to the ratchet tooth.

[0009] Further, one end of the transmission shaft away from the ratchet gear is rotatably connected to the support rod of the device, and a transmission rod is rotatably connected to the bottom of the ratchet gear.

[0010] Further, a groove is provided inside the ratchet tooth, and a convex tooth is provided on the top of the ratchet gear.

[0011] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0012] For the parking mechanism of the pedal mechanism, when the pedal mechanism performs parking braking on the transmission shaft, by moving the operating handle to the lower right corner direction, the connecting sleeve rod drives the operating rod to move downward, and then squeezes the connecting rod to rotate on the outer surface of the rotating shaft. At this time, the connecting rod is pushed upward, and the ratchet tooth disengages from the groove inside the ratchet gear, so that the transmission shaft can move without being limited; when parking braking is required, the operating handle is pulled back upward, the operating rod is lifted upward, the connecting rod is pushed downward, and at this time the ratchet tooth is locked inside the ratchet gear, thereby achieving the purpose of braking and parking of the pedal mechanism, which is more convenient and fast in operation and use.
