Description

Technical Field

[0001] This application relates to the field of brakes, and more specifically, to a reverse positioning mechanism, a reverse positioning motor, an anti-lock braking system, and a vehicle. Background Technology

[0002] The development of anti-lock braking systems (ABS) for two-wheeled vehicles stems from the urgent need for improved riding safety. Traditional braking systems are prone to wheel lock-up during emergency braking, leading to skidding or rollovers, especially on wet or uneven surfaces where the risk is even higher.

[0003] In anti-lock braking systems (ABS), high-frequency intermittent braking prevents wheel lock-up. Braking force is adjusted by a piston driven by a rotating motor shaft pressing against a pressure chamber. However, improper motor starting position can lead to excessive initial torque, affecting system stability. This is because when the motor starts in the wrong position, the controller cannot accurately apply current, causing the shaft to generate excessive torque instantaneously. This sudden increase in pressure within the pressure chamber can result in delayed or fluctuating braking response. Solving this problem requires optimizing the motor's initial position and employing a soft-start strategy to ensure a smooth start, thereby improving the reliability and braking performance of the ABS system.

[0031] Through the above technical solution, a reverse positioning mechanism can be installed on the motor shaft. When the shaft rotates in the forward direction, the positioning key slides on the positioning seat, moving from the back of the one-way boss to the front. When the shaft rotates in the reverse direction, the positioning key meets the front of the one-way boss, stopping the relative movement between the positioning key and the positioning seat, and thus braking the shaft. At the same time, for a motor equipped with this reverse positioning mechanism, when the eccentric wheel contacts the elastic seal, the setting position of the one-way boss determines the initial starting position of the motor. That is, the contact point between the eccentric wheel and the elastic seal, the eccentric point of the eccentric wheel, and the rotation point of the eccentric wheel are all on a straight line. At this time, when the shaft rotates, the resistance of the elastic seal to the eccentric wheel in the direction perpendicular to the straight line containing these three points is zero, which can ensure the smooth start of the motor. This solution has a reasonable structure, is installed in the anti-lock braking system of a two-wheeled vehicle, saves space, and has low cost.

[0041] Please refer to Figures 1 to 19 The following describes the reverse positioning mechanism, reverse positioning motor, anti-lock brake, and vehicle used in the embodiments of the present utility model. Example 1

[0042] Figure 1 This is a front view of the reversing positioning mechanism for the anti-lock braking system in Embodiment 1. The reversing positioning mechanism provided in this application is applied to the reversing positioning of the motor shaft of a two-wheeled vehicle anti-lock braking system. It aims to prevent excessive initial torque due to an improper starting position of the shaft when the anti-lock brake motor starts, which could affect system stability.

[0043] The reverse positioning mechanism for the anti-lock braking system includes a rotating shaft 1 and a positioning component 2, which are connected by a bracket 3. The positioning component 2 includes an elastic element 214, a positioning seat 211, and a positioning key 212. The positioning seat 211 is provided with at least one one-way boss 213. When the rotating shaft 1 rotates in the forward direction, one end of the positioning key 212 elastically abuts against the positioning seat 211 and slides on its surface. When the rotating shaft 1 rotates in the reverse direction, the positioning key 212 collides with the one-way boss 213, and the one-way boss 213 stops the sliding of the positioning key 212. At the same time, the rotating shaft 1 stops rotating.

[0044] For details, please refer to the following: Figure 13 In this embodiment, the positioning key 212 includes a pawl and a pawl seat 2124. The pawl consists of a pawl head 2121 and a pawl tail 2122. In the working state, the pawl head 2121 abuts against the positioning seat 211, and the pawl tail 2122 is fixedly connected to the pawl seat 2124. Simultaneously, the pawl seat 2124 is fixedly connected to the bracket 3. The pawl tail 2122 and the pawl seat 2124 are connected via a connecting shaft 2123. A torsion spring is fitted on the connecting shaft 2123 to provide elastic restoring force to the pawl in the direction of rotation around the connecting shaft 2123, thus ensuring that the pawl head 2121 abuts against the surface of the positioning seat 211 without affecting the forward rotation of the rotating shaft 1.

[0045] In this embodiment, the positioning seat 211 is sleeved on and fixed to the rotating shaft 1, and rotates synchronously with the rotating shaft 1 when the rotating shaft 1 rotates. The positioning seat 211 is disc-shaped, and an arc surface with a gradually increasing radius is formed on the outer periphery of the positioning seat 211. After the arc surface surrounds the rotating shaft 1 once, the cross-section formed by the radius difference is the one-way boss 213.

[0046] Figure 9 This is a schematic diagram of the reverse positioning mechanism for anti-lock braking systems installed on a motor. The motor body 4 is connected and fixed to the bracket 3. When the motor drives the rotating shaft 1 in the forward direction (… Figure 1 When rotating counterclockwise, the positioning seat 211 rotates accordingly. The function of the elastic element 214 is to make the pawl head 2121 abut against the outer circumferential arc surface of the positioning seat 211, and the pawl head 2121 slides over the outer circumferential surface of the positioning seat 211; when the rotating shaft 1 rotates in the reverse direction (…), the positioning seat 211 rotates counterclockwise. Figure 1 (When rotating clockwise), the pawl head 2121 meets the cross-section, i.e., the one-way boss 213. At this time, the rotation of the positioning seat 211 is stopped, and the rotating shaft stops.

[0047] Figure 10 This is a three-dimensional structural diagram of the reversible positioning motor assembled with the hydraulic pressure regulator. The hydraulic pressure regulator includes an oil reservoir 6, a pressing component 7, and an elastic sealing component 8. Figure 11 (as indicated by the Chinese designation) and oil pipe 9 ( Figure 11(Illustrated). In this embodiment, the elastic seal 8 is an elastic diaphragm, which can be replaced by a rubber stopper, piston, or similar structure in other cases. The elastic diaphragm covers the open side of the oil reservoir 6 by means of adhesive bonding, welding, etc., and the volume of the oil reservoir 6 can be adjusted by its elastic expansion and contraction; the extrusion component 1 is an eccentric wheel, which can be replaced by a cam or similar structure in other cases; the eccentric wheel is mounted on the rotating shaft 1 and rotates synchronously with the rotating shaft 1. During the rotation, its outer circumferential surface abuts against the elastic diaphragm, with the contact point being 703. The eccentric point of the eccentric wheel is 701, and the rotation point is 702, as shown. Figure 17 As illustrated, when the contact point is 703, and the eccentric point 701 and rotation point 702 of the eccentric wheel are on a straight line, the resistance from the elastic diaphragm is minimal when the motor starts. In an even better state, when the eccentric point 701 of the eccentric wheel is between the rotation point 702 and the contact point 703 during startup, the elastic diaphragm is in a state of being compressed and stretched. Its elastic restoring force acts on the outer circumference of the eccentric wheel, providing a certain assistance in its rotational direction after the eccentric wheel starts, making the motor run more smoothly.

[0048] Figure 11 The diagram illustrates the structure of an anti-lock braking system (ABS). The ABS includes a brake unit, a hydraulic pressure regulator, and a reverse positioning motor. The brake unit comprises a control element 11, a caliper 5, and a disc 10. The control element 11, hydraulic pressure regulator, and caliper 5 are connected in series via an oil pipe 9. When the control element 11 is tightened, hydraulic oil enters the hydraulic pressure regulator through the oil pipe 9. The reverse positioning motor then starts, causing the compression element 7 to repeatedly compress the elastic seal 8, resulting in changes in hydraulic pressure. When the hydraulic oil pressure increases, the caliper 5 clamps the disc; when the hydraulic pressure decreases, it releases, achieving a periodic braking effect and thus preventing lock-up. After braking, the motor reverses, and the positioning key 212 meets the one-way boss 213, stopping the motor and returning the motor shaft 1 to its original starting position. This ensures that the eccentric wheel is in the same state for the next start. Figure 17 As shown, the contact point is 703, the eccentric point 701 and the rotation point 702 of the eccentric wheel are on a straight line, the resistance from the elastic diaphragm in the horizontal direction is 0, and the motor starts smoothly. Example 2

[0049] like Figure 2 As shown, the difference from Embodiment 1 is that the reversing positioning mechanism positioning seat 211 for the anti-lock braking mechanism in this embodiment is disc-shaped, and the one-way boss 213 is movably installed on the original outer peripheral surface of the positioning seat 211, as shown. Figure 14 As shown, the outer periphery of the disk has a groove 2111 that can accommodate the one-way boss 213. An elastic element 214 is installed in the groove 2111, providing elastic force for the one-way boss 213 to extend out of the groove 2111. In this embodiment, the pawl tail 2122 is fixedly connected to the pawl seat 2124. Thus, the reverse positioning function is achieved in the same way as in Embodiment 1. Example 3

[0050] like Figure 5 and Figure 6 As shown, the difference from Embodiment 1 is that the positioning seat 211 of the reversing positioning mechanism for the anti-lock braking system in this embodiment is disc-shaped, and the one-way boss 213 is fixedly mounted on the disc surface of the positioning seat 211. In order to ensure that the positioning key 212 slides smoothly on the positioning seat 211, a slope with a gradually decreasing horizontal height around the center of the disc is formed on the disc surface of the positioning seat 211. After the slope surrounds the center of the disc once, the cross-section formed by the height difference of the slope is the one-way boss 213.

[0051] In this embodiment, both the pawl tail 2122 and the pawl seat 2124 of the positioning key 212 have connecting holes. The connecting shaft 2123 passes through the connecting holes to connect the pawl tail 2122 and the pawl seat 2124 together. The elastic element 214 is a compression spring, which is sleeved on the connecting shaft 2123. Between the pawl tail 2122 and the pawl seat 2124, it provides an elastic restoring force for the pawl to press against the surface of the positioning seat 211, so as to ensure that the pawl head 2121 abuts against the surface of the positioning seat 211. Thus, the reverse positioning function is achieved in the same way as in embodiment 1. Example 4

[0052] like Figure 7 , Figure 8 and Figure 15 As shown, the difference from Embodiment 3 is that in this embodiment, the pawl tail 2122 of the reverse positioning mechanism for the anti-lock braking system is fixedly connected to the pawl seat 2124, and the one-way boss 213 is movably disposed on the disk surface of the positioning seat 211. The positioning seat 211 is provided with a groove 2111 that can accommodate the one-way boss 213, and an elastic member 214 is disposed in the groove 2111 to provide elastic force in the direction in which the one-way boss 213 extends out of the groove 2111. Thus, the reverse positioning function is achieved in the same way as in Embodiment 3. Example 5

[0053] like Figure 3 and Figure 18As shown, the difference from Embodiment 1 is that the positioning seat 211 of the reversing positioning motor provided in this embodiment is annular, including an inner ring and an outer ring. The inner ring of the positioning seat 211 has an arc surface with a gradually increasing radius. The cross-section formed by the radius difference after the arc surface circles the central axis is the one-way boss 213 of this embodiment. The positioning key 212 is a pawl. The pawl head 2121 abuts against the inner ring arc surface, and the pawl tail 2122 has a mounting hole 2125. The rotating shaft 1 passes through the mounting hole and connects the pawl and the torsion spring. The two torsion arms of the torsion spring are fixedly connected to the pawl and the rotating shaft 1 by welding or bonding. In this embodiment, the pawl tail 2122 has a slot 2126, and the torsion arm of the torsion spring abuts against the wall of the slot 2126, which can better provide torque, causing the positioning key 212 to abut against the surface of the positioning seat 211. Thus, the reversing positioning function is achieved similarly to that of Embodiment 1. Example 6

[0054] like Figure 4 and Figure 16 As shown, the difference from Embodiment 5 is that the positioning key 212 is fixedly connected to the rotating shaft 1, the positioning seat 211 is annular, and the one-way boss 213 is movably connected to the inner ring of the positioning seat 211. A groove 2111 is formed on the inner ring of the positioning seat 211 to accommodate the one-way boss 213. The elastic element 214 is a spring installed in the groove 2111 to provide elastic force for the one-way boss 213 to extend out of the groove. Thus, the reverse positioning function is achieved in the same way as in Embodiment 5. Example 7

[0055] refer to Figure 19 Unlike Embodiment 3, in this embodiment, the reversing positioning mechanism for an anti-lock braking system uses a pawl as the positioning key 212. The tail of the pawl 2122 is fitted onto the rotating shaft 1 and is slidable along the axial direction. The elastic element 214 is a compression spring, also fitted onto the rotating shaft 1. The two ends of the compression spring are respectively bonded / welded to the surface of the rotating shaft 1 and the tail of the pawl 2122, providing elastic pressure for the pawl to press against the surface of the positioning seat 211, keeping the head of the pawl 2121 in contact with the surface of the positioning seat 211. Thus, the reversing positioning function is achieved in the same way as in Embodiment 3. Example 8

[0056] refer to Figure 19 Unlike Embodiment 4, in the reverse positioning mechanism for the anti-lock braking system provided in this embodiment, the positioning key 212 is a pawl. The tail of the pawl 2122 is fitted onto the rotating shaft 1 and fixed. The head of the pawl 2121 abuts against the surface of the positioning seat 211, thus achieving the reverse positioning function similar to that in Embodiment 4.

[0057] In the above embodiments, when the longitudinal section of the movable unidirectional boss 213 is a right-angled triangle, the unidirectional boss 213 can be inserted into or protrude from the groove more smoothly. It can be understood that the gentler the slope of the unidirectional boss 213, the smoother the sliding of the positioning key 212 on the surface of the positioning seat 211 when the rotating shaft 1 rotates forward.

[0058] In the above embodiments, the elastic seal 8 can be an elastic diaphragm that is attached to the side of the oil reservoir 6 with an opening, or it can be a rubber plug or piston that is plugged into the opening. It is understood that the inner side of the corresponding opening should have a contact surface suitable for the sliding of the rubber plug or piston.

[0059] Understandably, during the operation of the aforementioned reversing positioning motor, the motor speed and direction can be adjusted via a motor controller or microcontroller / microcontroller. The motor controller or microcontroller / microcontroller receives speed signals collected from the speed detection element. When the speed of the two-wheeled vehicle exceeds a threshold, the anti-lock braking system (ABS) is activated, and the motor starts rotating forward. When the speed falls below a threshold, the motor stops rotating, and then the motor controller or microcontroller / microcontroller adjusts the motor to rotate in reverse.
