The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
In the present disclosure, without being stated to the contrary, the term "up and down" refers to the orientation or position relationship of the product that is usually placed when in use, and can be understood as up and down along the gravity direction, and also corresponds to the "up and down" in the drawing; "front" is front in the horizontal direction, specifically the front of the vehicle as referred to in this disclosure; "inner" refers to "inner" relative to the contour of the component or structure itself. In addition, it should be noted that terms such as "first", "second", and the like are used for distinguishing one element from another, and have no order or importance.
An embodiment of the present disclosure provides an auxiliary brake apparatus for a vehicle, which includes a brake pedal 100 and a linear driving member for coupling with a vehicle body, the linear driving member being coupled with the brake pedal 100 to drive the brake pedal 100 to move in an axial direction of the linear driving member, the auxiliary brake apparatus having an operating position in which the brake pedal 100 is extended for contacting the ground and a non-operating position in which the brake pedal 100 is retracted, with reference to fig. 1.
Through the technical scheme, under the effect of the linear driving piece, the linear driving piece can drive the brake plate 100 to move along the axis direction of the linear driving piece, so that the brake plate 100 can be in contact with the ground, the contact area between the vehicle and the ground is increased by making the brake plate 100 in contact with the ground, the friction force of the ground facing the vehicle can be increased, the braking distance of the vehicle is shortened, the safety performance of the vehicle is favorably improved, and the probability of accidents is reduced. In addition, the auxiliary braking device is used for reducing the abrasion of the vehicle tire and enabling the vehicle to be free from being provided with an ABS. Particularly, when the original brake system of the vehicle fails, the auxiliary brake device can effectively brake the vehicle, so that the safety performance of the vehicle is greatly improved.
It can be understood that when the brake plate 100 is attached to the ground, the contact area of the brake plate 100 with the ground is larger, so that the friction force between the vehicle and the ground can be increased. Also, brake pedal 100 is adapted to move along a trajectory parallel to the ground due to the limited space at the bottom of the vehicle. That is, when the auxiliary brake device is not operated, the brake pad 100 is away from the ground and parallel to the ground, and when the auxiliary brake device is operated, the brake pad 100 is close to and attached to the ground and parallel to the ground, so that the brake pad 100 is always lifted and lowered in a horizontal state with respect to the ground between the operating position and the non-operating position.
Referring to fig. 1, in the embodiment of the present disclosure, the linear actuator is disposed to be inclined with respect to the brake pedal 100 to drive the brake pedal 100 to move toward the front lower side of the vehicle body, and since the linear actuator is disposed to be inclined with respect to the brake pedal 100 and the brake pedal 100 is disposed parallel to the ground, the linear actuator is inclined with respect to the ground, or the linear actuator is disposed to be inclined with respect to the vehicle body and extends toward the front lower side of the vehicle. In this case, when the braking vane 100 is driven by the inclined linear driving member to move to the front lower side of the vehicle body and contact with the ground, the acting force of the linear driving member on the ground can be reduced, the damage of the connection part of the linear driving member and the vehicle body can be avoided, and the service life of the auxiliary braking device can be prolonged.
Referring to fig. 1, in the embodiment of the present disclosure, a brake rotor 100 includes a main body 101, and the main body 101 is configured to contact with a ground surface, so that the main body 101 is disposed parallel to the ground surface and has a plate-shaped structure. The front end of the main body 101 is provided with an avoiding part 102 which extends in an upward inclined manner relative to the main body 101, an included angle between the avoiding part 102 and the main body 101 is an obtuse angle, or the avoiding part 102 extends in a forward upward direction relative to the main body 101, so that an avoiding space can be formed between the avoiding part 102 and the ground, when a vehicle travels forwards and encounters an obstacle such as a stone or an uneven road surface, the avoiding part 102 contacts the obstacle such as the stone and enables the main body 101 to be lifted, so that the obstacle such as the stone passes through, the setting of the avoiding part 102 can enable the brake pad 100 to smoothly pass through the obstacle or the uneven road surface, and further enable the vehicle to smoothly pass through the obstacle or the uneven road surface. In addition, the situation that the vehicle collides with an obstacle and turns over forwards due to the fact that the speed of the vehicle is too high can be avoided.
The length of the escape part 102 may be equal to the width of the main body part 101, so that the overall shape of the brake pad 100 is rectangular, which is advantageous for increasing the contact area between the brake pad 100 and the ground.
Referring to fig. 1, in one embodiment of the present disclosure, the main body 101 and the avoiding portion 102 are in arc transition, so that the bottom side of the connection portion between the main body 101 and the avoiding portion 102 is a cambered surface, which enables the brake pad 100 to pass through obstacles or uneven road surfaces more smoothly.

In the embodiment of the disclosure, the main body portion 101 and the avoiding portion 102 are integrally formed, that is, the main body portion 101 and the avoiding portion 102 are formed by bending a flat plate structure, so that the connection strength between the main body portion 101 and the avoiding portion 102 can be enhanced, and the difficulty of the processing process is simplified.

In addition, when the piston cylinder 110 is a hydraulic cylinder, the auxiliary brake device further includes a brake pump (not shown) connected to the cylinder body, and the brake pump may be installed on the vehicle body by supplying hydraulic oil to the hydraulic cylinder through the brake pump so as to push the first piston rod 111 and the second piston rod 112.
