However, the existing mechanical hand brake pull rod occupies a large space in a cab, is not attractive, is difficult to pull up or release a hand brake, and often causes accidents due to the fact that a user forgets to pull a handle to brake and slides a car.

To this end, an embodiment of the present utility model provides a mechanical automatic hand brake, referring to fig. 1 and 2, the automatic hand brake includes: the device comprises a shell 100, a moving part 200, a driving part 300 and a limiting assembly 400, wherein a cavity is arranged in the shell 100; the moving member 200 is movably disposed in the cavity and connected to the brake by a hand brake cable 600, the moving member 200 being configured to switch between an unlocked position and a locked position; when the moving part 200 is positioned at the unlocking position, the brake is in a braking state; when the moving part 200 is positioned at the locking position, the brake is in an unlocking state; the driving member 300 is connected to the moving member 200 and the housing 100, respectively, for driving the moving member 200 to move from the locking position to the unlocking position; the limiting assembly 400 is connected to the housing 100 and the triggering device for limiting the moving member 200 in the locking position and releasing the limiting of the moving member 200 after being triggered by the triggering device.

It should be noted that the triggering device may be a hand brake button or a main driving door, in this embodiment, the triggering device is a main driving door, and the main driving door is connected with the limiting component 400 through a pull wire; specifically, one end of the pull wire is connected to the restraint assembly 400 and the other end of the pull wire is connected to the primary steering door. The moving member 200 is also connected with a reset stay 500, one end of the reset stay 500 is connected with the moving member 200, and the other end is connected with a brake pedal, a clutch pedal or an accelerator pedal, and the moving member 200 can be moved from the unlocking position to the locking position by pressing the brake pedal, the clutch pedal or the accelerator pedal. The driving members 300 are preferably provided with two groups, and the two groups of driving members 300 are symmetrically arranged in the cavity.

The specific principle of the scheme is as follows: in the initial state, the moving member 200 is blocked in the locking position by the limiting assembly 400, and at this time, the driving member 300 is in a power storage state, and once the limiting assembly 400 releases the limiting of the moving member 200, the driving member 300 pushes the moving member 200 to move from the unlocking position to the locking position.

The effect of beautiful atmosphere is realized, the later maintenance is more convenient, and the maintenance cost is reduced. The hand brake can be braked in a door opening mode, so that the hand brake is labor-saving, and people with weak strength can use the hand brake conveniently.

In some other embodiments, the housing 100 is a rectangular structure with a top surface removed, and three holes are provided on the housing 100 for inserting the hand brake cable 600 and the reset cable 500. The specific material of the housing 100 may be made of stainless steel, or some other material with a certain rigidity. The mover 200 is slidably provided inside the housing 100, and in order to reduce friction of the mover 200 inside the housing 100, lubricating oil may be provided on a sliding track of the mover 200 and the housing 100. Thus, on one hand, the smoothness of the movement of the moving member 200 can be improved, and on the other hand, the abrasion to the moving member 200 can be reduced, and the service life of the moving member 200 can be prolonged. The moving member 200 may be made of some metal materials with wear resistance, and in particular, may be stainless steel.

An embodiment of the driving member 300 is provided below, with reference to fig. 1 and 2, in which the driving member 300 is a spring that is in compression when the moving member 200 is in the locked position. Specifically, one end of the spring is fixedly connected with the inner wall of the housing 100, and the other end is fixedly connected with the moving member 200. The hand brake cable 600 is connected with the moving member 200 through the inside of the spring, and the hand brake cable 600 has a double-back structure. The length of the spring can be designed according to practical situations, but the following needs to be satisfied: when the moving member 200 is in the locking position, the spring is in a power storage state, and when the moving member 200 is unlocked, the spring has enough elastic force to push the moving member 200 to move to the unlocking position, and meanwhile, the hand brake can be in a braking state. The use of a spring for the driver 300 has the following advantages: firstly, the mechanical properties of the spring itself can be such that it has two states of accumulation and force generation, by switching between which the switching of the movement 200 between the locking position and the unlocking position is satisfied.

Embodiments of the relative positions of the mover 200 and the defining assembly 400 are provided below, with the defining assembly 400 being switched with the mover 200 between a first position and a second position; in the first position, the limiting assembly 400 is in positive engagement with the mover 200; in the second position, the restraint assembly 400 releases the restraint of the mover 200. The first and second positions are relative positions of the mover 200 and the limiting assembly 400. Specifically, the moving member 200 moves along the length direction of the bottom wall of the housing 100, the limiting assembly 400 moves perpendicular to the moving direction of the moving member 200, and the trajectories of the two have an intersection. The first and second positions are specifically the sides of the mover 200 defining the assembly 400. When the moving member 200 is on one side of the limiting assembly 400, the limiting assembly 400 locks the moving member 200, i.e. when the limiting assembly 400 contacts the moving member 200, the limiting assembly 400 can block the moving member 200 from further movement; when the mover 200 is located on the other side of the limiter assembly 400, the limiter assembly 400 will unlock the mover 200, i.e., when the two are in contact, the limiter assembly 400 will not prevent further movement of the mover 200.

Referring to fig. 1, the limiting assembly 400 is disposed in the cavity through the fixing frame 700, the fixing frame 700 has a U-shaped structure, the opening is disposed toward the housing 100, and two ends of the fixing frame 700 are respectively connected to two sides of the housing 100 through a plurality of bolts. In some other embodiments, the mount 700 may also be fixedly coupled to the housing 100. Mount 700 is made of a material having a certain rigidity, such as stainless steel. When the fixing frame 700 and the housing 100 are both made of stainless steel, they may be connected by welding.

Referring to fig. 1 and 3, the limiting assembly 400 includes a carriage 410 and a limiting block 430, the carriage 410 extending through the mount 700 and slidably coupled to the mount 700, a first end of the carriage 410 coupled to the trigger device, a second end of the carriage 410 coupled to the limiting block 430, the limiting block 430 including a vertical surface and a first inclined surface; in the first position, the mover 200 is located on the vertical surface side; in the second position, the mover 200 is located on the first incline side. By providing the stopper 430 with the vertical surface and the first inclined surface, the stopper 430 may have different effects on the moving member 200 when the moving member 200 passes the stopper 430. When the moving member 200 moves from the direction of the vertical surface of the limiting block 430, the vertical surface will clamp the moving member 200, preventing further movement of the moving member 200, and thus locking the moving member 200. When the moving member 200 moves from the first inclined plane direction of the limiting block 430, the first inclined plane will not block the moving member 200, and conversely, the moving member 200 will push the limiting block 430 to move upwards, and then pass through the limiting block 430.

An embodiment of further defining the moving member 200 is provided below, referring to fig. 1 and 2, a sliding block 210 is provided on the moving member 200, and a second inclined surface is provided on the sliding block 210, and the second inclined surface is used to slidingly mate with the first inclined surface. Specifically, the sliding block 210 is disposed corresponding to the limiting block 430, and when the moving member 200 moves to the position defining the assembly 400, the sliding block 210 can contact with the limiting block 430. Wherein the first and second inclined surfaces are arranged in parallel, which is relatively permissible with a certain error. When the sliding block 210 contacts with the limiting block 430, the bottom of the second inclined plane on the sliding block 210 contacts with the bottom of the first inclined plane of the limiting block 430, the two inclined planes are in sliding fit, and as the moving member 200 moves further, the two inclined planes further interfere, the sliding block 210 pushes the limiting block 430 to move upwards, so that the moving member 200 passes through the limiting assembly 400 and reaches the other side of the limiting assembly 400.

An embodiment of further defining the housing 100 is provided below, wherein the inner wall of the cavity is provided with a sliding rail 110, and the moving member 200 is slidably engaged with the sliding rail 110. The sliding rail 110 may specifically be a plurality of protruding strips disposed on the inner wall of the housing 100, the plurality of protruding strips are disposed at intervals, and two sides of the moving member 200 are slidably disposed between the protruding strips. It is also possible to provide a plurality of grooves on the inner wall of the housing 100, and to provide sliders on both sides of the moving member 200, which are matched with the grooves.

An embodiment for further defining the defining assembly 400 is provided below, where the defining assembly 400 further includes a return spring 420, a spring collar 440 is disposed at a second end of the sliding frame 410, the return spring 420 is sleeved on the sliding frame 410, one end of the return spring 420 abuts against the fixing frame 700, and the other end abuts against the spring collar 440. When the moving member 200 passes the stopper 430, the return spring 420 is compressed; after the moving member 200 passes through the limiting block 430, the limiting block 430 is reset under the action of the reset spring 420, so as to limit the moving member 200, and at this time, the moving member 200 is located at the locking position.
