Description

Technical Field

[0001] The present invention relates to the technical field of brakes, and in particular to a brake with an anti-lock structure for non-motor vehicles. Background Art

[0002] Non-motor vehicles are favored by the low- and middle-income classes in cities due to their advantages such as low cost, convenience, and environmental protection. The braking system of non-motor vehicles is crucial for driving safety. Traditional brakes directly brake the wheels through mechanical friction; Chinese Patent Authorization Publication No. CN115435032A discloses an electric vehicle braking device, including a brake bottom plate in the shape of a shell and a brake drum. A pair of brake shoes are symmetrically connected inside the brake bottom plate, and an adjusting mechanism for adjusting the distance between the two brake shoes is connected inside the brake bottom plate; one end of each of the two brake shoes is connected to the adjusting mechanism, and a brake oil cylinder is connected between the other ends of the two brake shoes; the two brake shoes are driven to rotate by the brake oil cylinder, so that the brake shoes contact the inner surface of the brake drum to achieve the braking effect; The above-mentioned prior art solutions have the following deficiencies: When the brake is suddenly applied, due to the rapid elongation of the brake oil cylinder, a sudden rigid contact is generated between the brake shoes and the brake drum, which easily causes the wheels to lock instantly, leading to the risk of skidding or tail flicking. Moreover, since the heat generated by the locked braking friction is concentrated in the contact area, it easily causes heat fade of the brake shoes, shortening the service life and reducing the braking stability. Therefore, there is room for improvement. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the problem that the prior art easily causes wheel lock-up during sudden braking. The present invention proposes a brake with an anti-lock structure for non-motor vehicles.

[0004] To solve the above technical problems, the technical solution adopted by the present invention is as follows: A brake for an anti-lock structure of a non-motor vehicle includes a brake housing, which is fixedly connected to the vehicle frame. A wheel axle penetrates through the interior of the brake housing. A brake disc is sleeved outside the wheel axle, and the brake disc is located inside the brake housing. A brake cover plate is installed on one side of the brake housing. On both sides inside the brake housing, brake shoes are rotatably connected. The brake shoes are respectively located on both sides of the brake disc. One ends of the two brake shoes are jointly connected to a brake opening and closing mechanism, and the brake opening and closing mechanism is movably connected to the inner wall of the brake housing. On the outer sides of the brake shoes away from the brake disc, tension springs are connected. One ends of the tension springs are fixedly connected to the inner side walls of the brake disc. Grooves are respectively formed on the inner sides of the brake shoes close to the brake disc. Inside the grooves, brake clamping plates are rotatably connected. Wear-resistant sheets are respectively fixed on the sides of the brake clamping plates close to the brake disc. Elastic columns are respectively connected between one ends of the brake clamping plates close to the brake opening and closing mechanism and the inner walls of the grooves. Inside the brake clamping plates close to the wear-resistant sheets, point braking magnets are respectively embedded. On the outer wall of the brake disc close to the brake shoes, a plurality of braking magnets are equidistantly embedded. The magnetic poles of adjacent braking magnets on the side close to the brake shoes are opposite. When the brake disc rotates, the point braking magnets alternately generate attraction and repulsion forces on the plurality of braking magnets in sequence.

[0005] Preferably, the brake opening and closing mechanism includes an L-shaped sliding plate slidably installed inside the brake housing. One end of the L-shaped sliding plate away from the brake disc is fixed with a brake wire, and one end of the brake wire penetrates to the outside of the brake housing. The other end of the L-shaped sliding plate is fixed with a guide plate. Straight guide holes are respectively formed on both sides of the guide plate. Guide columns respectively penetrate through the straight guide holes in a sliding manner. One ends of the guide columns are respectively connected to one ends of the adjacent brake shoes. The cross-section of the guide plate is in an inverted V shape, and the straight guide holes are distributed in an eight-shaped manner on the guide plate. The L-shaped sliding plate moves radially along the brake disc on the brake housing.

[0006] Preferably, a toothed ring is fixed on the outer end face edge of the brake disc. Guide assemblies are respectively arranged on the outer end faces of the brake shoes. Inside the guide assemblies, rotating rods are rotatably connected. Gears are respectively sleeved outside the rotating rods. A plurality of fan blades are evenly fixed on the outer ends of the rotating rods. When the brake shoes move closer to the brake disc, the gears mesh with the toothed ring.

[0007] Preferably, the guide assembly includes an arc-shaped guide frame fixed on the outer end face of the brake shoe. A slider is slidably installed inside the arc-shaped guide frame. One side of the slider is fixed with a spring B, and one end of the spring B is connected to the inner wall of the arc-shaped guide frame. The rotating rod is rotatably connected to the slider.

[0008] Preferably, one end of the arc-shaped guide frame is located at the center position of the brake shoe, and the other end of the arc-shaped guide frame is arranged along the direction away from the brake disc. There are two rotating rods, and the two rotating rods are collinearly distributed radially along the brake disc.

[0009] Preferably, a brake cover plate is installed on the outer side of the brake housing. A plurality of heat dissipation holes are provided on the brake cover plate. Air guide covers are fixed on the outer walls of the brake cover plate outside the heat dissipation holes. There are two groups of heat dissipation holes, with eight heat dissipation holes in each group. Each group of heat dissipation holes is equidistantly distributed along the outer edge direction of the brake disc. There are two groups of air guide covers, with eight air guide covers in each group. The opening directions of the two groups of air guide covers are opposite, and the opening direction of one of the groups of air guide covers faces the forward side of the vehicle.

[0010] Preferably, a plurality of annularly distributed sliding grooves are equidistantly arranged on the end face of the brake disc away from the brake cover plate. Centrifugal components are slidably connected inside the sliding grooves. Springs A are fixed inside the centrifugal components. One end of each spring A is connected to the inner wall of the sliding groove. A deceleration ring is fixed to the inner wall of the brake disc close to the sliding groove. The farthest end of the sliding groove away from the wheel axle is located below the adjacent brake magnet. The diameter of the deceleration ring is adapted to the distance between the farthest ends of two relatively distributed sliding grooves.

[0011] Preferably, the centrifugal component includes a sliding sleeve slidably installed inside the sliding groove. A deceleration block slidably penetrates through the inside of the sliding sleeve. An elastic block is fixed to the top end of the deceleration block. A deceleration magnet is embedded inside the deceleration block.

[0014] Compared with the prior art, the beneficial effects of the present invention include: Through the outward movement of the L-shaped slide plate, the guide post slides along the straight guide hole and drives the brake shoes on both sides to clamp and hold the brake disc inward, thereby achieving the braking effect on the brake disc. And by using the inertial rotation of the brake disc during braking, multiple brake magnets rotate synchronously. Under the alternating attraction and repulsion forces between different brake magnets and the point brake magnet, slight movement of the brake clamp inside the brake shoe is realized, so that the clamping force of the brake clamp on the outer wall of the brake disc is adjusted intermittently, achieving a high-frequency point brake effect, which is beneficial to preventing the rigid lock-up of the brakes in traditional brakes and reducing the risk of vehicle side slip. At the same time, during braking, the meshing of the toothed ring and the gear is utilized to synchronously drive the rotation of the fan blades by the inertial rotation of the brake disc, thereby increasing the air flow on the braking side of the brake clamp and the brake disc. Then, in cooperation with the heat dissipation holes and the air guide covers, the outward transmission of the frictional heat during braking is further improved, delaying the heat fade phenomenon of the brake clamp and increasing the service life of the brake.

Detailed embodiments

[0017] It is easy to understand that according to the technical solution of the present invention, without changing the essence of the present invention, those of ordinary skill in the art can propose various interchangeable structural forms and implementation methods. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as the whole of the present invention or as a limitation or restriction on the technical solution of the present invention.

[0018] Embodiment 1: In order to solve the problems that the prior art is prone to wheel lock-up during sudden braking, and at the same time, it is easy to increase the heat fade of the brake shoe during lock-up, affecting the service life of the brake, the following solution is disclosed. Specifically, as Figures 1 - 3 、 Figures 6 - 8 shown: A brake for an anti-lock structure of a non-motor vehicle includes a brake housing 1, the brake housing 1 is fixedly connected to the vehicle frame, a wheel shaft penetrates through the interior of the brake housing 1, a brake disc 2 is sleeved outside the wheel shaft, the brake disc 2 is located inside the brake housing 1, a brake cover plate 6 is installed on one side of the brake housing 1, both sides inside the brake housing 1 are rotatably connected with brake shoes 3, the brake shoes 3 are respectively located on both sides of the brake disc 2, one ends of the two brake shoes 3 are jointly connected with a brake opening and closing mechanism 4, the brake opening and closing mechanism 4 is movably connected with the inner wall of the brake housing 1, tension springs 5 are connected to the outer sides of the brake shoes 3 far away from the brake disc 2, one ends of the tension springs 5 are fixedly connected to the inner side walls of the brake disc 2, grooves 14 are respectively formed in the inner sides of the brake shoes 3 close to the brake disc 2, brake clamping plates 10 are rotatably connected inside the grooves 14, wear-resistant sheets 13 are fixed on the sides of the brake clamping plates 10 close to the brake disc 2, elastic columns 11 are connected between one ends of the brake clamping plates 10 close to the brake opening and closing mechanism 4 and the inner walls of the grooves 14, point brake magnets 12 are respectively embedded on one side of the brake clamping plates 10 close to the wear-resistant sheets 13, a plurality of brake magnets 9 are equidistantly embedded on the outer wall of the brake disc 2 close to the brake shoes 3, the magnetic poles of adjacent brake magnets 9 on the side close to the brake shoes 3 are opposite, when the brake disc 2 rotates, the point brake magnets 12 alternately generate attraction and repulsion forces on the plurality of brake magnets 9 in sequence; The brake opening and closing mechanism 4 includes an L-shaped sliding plate 41 slidably installed inside the brake housing 1, a brake wire 45 is fixed to one end of the L-shaped sliding plate 41 far away from the brake disc 2, one end of the brake wire 45 penetrates to the outside of the brake housing 1, a guide plate 42 is fixed to the other end of the L-shaped sliding plate 41, straight guide holes 44 are respectively formed on both sides of the guide plate 42, guide columns 43 are slidably penetrated inside the straight guide holes 44, one ends of the guide columns 43 are respectively connected to one ends of the adjacent brake shoes 3, the cross-section of the guide plate 42 is in an inverted V shape, the straight guide holes 44 are distributed in an eight-character shape on the guide plate 42, and the L-shaped sliding plate 41 moves radially along the brake disc 2 on the brake housing 1; Specifically, as Figures 1 - 3As shown, during braking, since the magnetic poles of the multiple braking magnets 9 on the side of the brake disc 2 close to the brake shoe 3 alternate between N / S poles, when the brake disc 2 rotates inertially, the spot braking magnet 12 contacts different magnetic pole regions in sequence, thereby alternately generating magnetic attraction / repulsion forces, thus realizing slight rotation of the braking clamp 10, thereby changing the clamping force of the wear-resistant piece 13 on the brake disc 2, achieving an intermittent clamping effect. By using intermittent automatic adjustment, when the brake cable 45 is tightened for braking, the wear-resistant piece 13 automatically achieves a high-frequency spot braking effect on the brake disc 2, thereby preventing sudden locking of the brake disc 2; A toothed ring 19 is fixed to the outer end face edge of the brake disc 2, guiding components 20 are arranged on the outer end faces of the brake shoes 3, rotating rods 21 are rotatably connected inside the guiding components 20, gears 22 are sleeved on the outer parts of the rotating rods 21, and a plurality of fan blades 23 are evenly fixed to the outer ends of the rotating rods 21. When the brake shoes 3 move closer to the brake disc 2, the gears 22 mesh with the toothed ring 19; The guiding component 20 includes an arc-shaped guiding frame 201 fixed to the outer end face of the brake shoe 3, a slider 202 is slidably installed inside the arc-shaped guiding frame 201, a spring B203 is fixed to one side of the slider 202, and one end of the spring B203 is connected to the inner wall of the arc-shaped guiding frame 201. The rotating rod 21 is rotatably connected to the slider 202; One end of the arc-shaped guiding frame 201 is located at the center position of the brake shoe 3, the other end of the arc-shaped guiding frame 201 is arranged along the direction away from the brake disc 2, there are two rotating rods 21, and the two rotating rods 21 are collinearly distributed along the radial direction of the brake disc 2; Specifically, as Figure 6 、 Figure 7 shown, by means of the action of the arc-shaped guiding frame 201, when the brake shoe 3 moves closer to the brake disc 2 for braking, the slider 202 can slide along the arc-shaped guiding frame 201 to ensure that the toothed ring 19 always meshes with the gear 22 during the continuous clamping braking process of the brake shoe 3. Then, by using the inertial rotation of the brake disc 2, the rotation of the fan blades 23 is realized to improve the air flow at the braking friction position, thereby timely discharging the frictional heat generated during braking, reducing the frictional heat deformation of the wear-resistant piece 13. On the one hand, the service life of the wear-resistant piece 13 is improved, and on the other hand, the wear-resistant piece 13 is prevented from being excessively deformed by heat in a short time, avoiding locking; A brake cover plate 6 is installed on the outer side of the brake housing 1, a plurality of heat dissipation holes 7 are opened on the brake cover plate 6, air guiding covers 8 are fixed to the outer walls of the brake cover plate 6 outside the heat dissipation holes 7, there are two groups of heat dissipation holes 7, each group of heat dissipation holes 7 has eight, each group of heat dissipation holes 7 is equidistantly distributed along the outer edge direction of the brake disc 2, there are two groups of air guiding covers 8, each group of air guiding covers 8 has eight, and the opening directions of the two groups of air guiding covers 8 are opposite, and the opening direction of one group of air guiding covers 8 faces the forward side of the vehicle; Specifically, as Figure 1 、Figure 8 As shown, by utilizing the function of the air guide cover 8, when the vehicle brakes, the airflow is further guided to promote the airflow to enter the interior of the brake housing 1 along the opening of the front air guide cover 8 and discharge outward along the rear air guide cover 8, improving the air exchange inside and outside the brake housing 1 during braking and enhancing the heat dissipation effect.

[0019] In this embodiment, when braking, pull the handlebar brake, so that the brake wire 45 pulls the L-shaped slide plate 41 to move outward, making the guide plate 42 move synchronously. Since the guide post 43 is always located inside the straight guide hole 44, the guide post 43 moves toward the side close to the brake disc 2 under the action of the straight guide hole 44, so that the guide post 43 drives the brake shoe 3 to rotate and approach the brake disc 2 along the rotating shaft, making the tension spring 5 stretch, and making the wear-resistant piece 13 fit and rub against the outer wall of the brake disc 2. By using the synchronous clamping and friction of the two wear-resistant pieces 13, the braking of the brake disc 2 is realized and stopped. Due to the inertial rotation of the brake disc 2 during braking, the brake disc 2 drives the brake magnet 9 to rotate synchronously. Since the outer magnetic properties between adjacent brake magnets 9 are different, during the clamping process of the wear-resistant piece 13, the point brake magnet 12 successively exerts attractive and repulsive forces on different brake magnets 9. Since the brake disc 2 is fixed on the wheel axle, the attractive and repulsive forces successively drive the brake clamp 10 to rotate slightly, and its rotation direction is successively approaching and moving away from the brake disc 2 alternately, and the elastic column 11 deforms. By using the slight rotation of the brake clamp 10 inside the brake shoe 3, the clamping tightness between the wear-resistant piece 13 and the outer wall of the brake disc 2 is adjusted in real time during braking, achieving the effect of point braking, thus effectively preventing the occurrence of locking; At the same time, during the process of the brake shoe 3 approaching the brake disc 2, the gear 22 approaches the gear ring 19 and meshes. Under the inertial rotation of the brake disc 2 during braking, the gear ring 19 drives the gear 22 to rotate. Since the brake shoe 3 continuously moves toward the brake disc 2, the gap between the two continuously decreases, making the gear ring 19 drive the gear 22 to rotate, and making the rotating rod 21 drive the slider 202 to slide inside the arc-shaped guide frame 201, stretching the spring B203. Under the action of the tensile force of the spring B203, the stable meshing of the gear ring 19 and the gear 22 during braking is ensured, so that the gear 22 drives the rotating rod 21 to rotate, and the fan blade 23 rotates. Since the fan blade 23 is located at the end face of the brake shoe 3, the fan blade 23 increases the air flow rate around the friction surface of the wear-resistant piece 13 and the brake disc 2, so as to quickly transfer the heat at the braking friction part outward through the heat dissipation holes 7, reducing the friction heat deformation rate of the wear-resistant piece 13 during braking, thereby further preventing sudden locking and improving the braking stability; At the same time, taking advantage of the decelerating forward movement of the vehicle during braking and the opening effect of the air deflector 8, the air flow is made to enter the interior of the brake housing 1 through the heat dissipation holes 7 along the air deflector 8, so as to further improve the air flow effect inside and outside the brake housing 1 during braking, and further improve the heat dissipation effect.

[0020] Embodiment 2: In order to further reduce the probability of sudden braking of non-motor vehicles and further automatically reduce the speed in the overspeed state, the following solution is thus disclosed. Specifically, as Figure 4 、 Figure 5 shown: A plurality of annularly distributed sliding grooves 16 are equidistantly arranged on the end face of the brake disc 2 away from the brake cover plate 6. The inside of each sliding groove 16 is slidably connected with a centrifugal component 18. Springs A17 are fixedly arranged inside the centrifugal components 18. One ends of the springs A17 are connected to the inner walls of the sliding grooves 16. A deceleration ring 15 is fixed to the inner wall of the brake disc 2 close to the sliding grooves 16. The farthest end of the sliding groove 16 away from the wheel axle is located below the adjacent brake magnet 9. The diameter of the deceleration ring 15 is adapted to the distance between the farthest ends of two relatively distributed sliding grooves 16; Specifically, as Figure 4 shown, when the centrifugal force is greater than the pulling force of the spring A17, by using the positive correlation between the sliding distance of the centrifugal component 18 in the sliding groove 16 and the vehicle speed, the centrifugal component 18 and the deceleration ring 15 are used to generate contact friction in the overspeed state, so as to resist the forward rotational force of the brake disc 2, thereby achieving the effect of speed reduction and speed limit and reducing the possibility of sudden braking; The centrifugal component 18 includes a sliding sleeve 181 slidably installed inside the sliding groove 16. A deceleration block 182 slides through the inside of the sliding sleeve 181. An elastic block 184 is fixed to the top end of the deceleration block 182. A deceleration magnet 183 is embedded inside the deceleration block 182. The magnetic poles of the deceleration magnet 183 and the adjacent brake magnet 9 repel each other; The sliding grooves 16 are collinearly distributed along the radius of the brake disc 2. The sliding direction of the deceleration block 182 and the sliding direction of the sliding sleeve 181 are perpendicularly distributed; Specifically, as Figure 5 shown, by using the mutual repulsion between the deceleration magnet 183 and the adjacent brake magnet 9, the contact tightness between the deceleration block 182 and the deceleration ring 15 in the overspeed state is increased, thereby increasing the frictional resistance; The bottom end face of the deceleration block 182 is a curved surface, the inner side face of the deceleration ring 15 is a chamfered curved surface, and both the bottom end face of the deceleration block 182 and the inner side face of the deceleration ring 15 are frosted textures; Specifically, as Figure 5 shown, by using the curved surfaces and frosted textures of the deceleration ring 15 and the deceleration block 182, high friction between the two is ensured. At the same time, when the deceleration block 182 slides radially along the brake disc 2, the bottom end face of the deceleration block 182 can smoothly come into contact friction with the inner side face of the deceleration ring 15.

[0021] In this embodiment, during the forward movement of the vehicle, when the wheel speed exceeds the limit, the centrifugal force is relatively large at this time, and the centrifugal force is greater than the elastic tensile force of spring A17, causing the sliding sleeve 181 to move outward along the sliding groove 16 to the maximum position, so that the sliding sleeve 181 and the magnetic pole at the inner end of the braking magnet 9 are in a relative position. At this time, the deceleration magnet 183 and the braking magnet 9 are in relative positions, and since the magnetic poles of the opposite faces are the same at this time, the deceleration magnet 183 is repelled, so that the deceleration magnet 183 moves downward along the sliding sleeve 181, and the bottom end surface of the deceleration magnet 183 is tightly abutted against the inner side surface of the deceleration ring 15. At this time, since the brake disc 2 is continuously rotating, the deceleration magnet 183 rotates by friction along the inner side surface of the deceleration ring 15. Since the deceleration ring 15 is fixed on the inner wall of the brake housing 1 and the brake housing 1 is fixed to the vehicle frame, the brake disc 2 is subjected to the frictional resistance of the deceleration ring 15 when rotating, thereby resisting the rotational force of the brake disc 2, achieving the effect of automatic deceleration and speed limit, improving the safety of the vehicle's forward movement, and at the same time using automatic deceleration to reduce sudden braking behavior and further reduce the possibility of brake lock-up.

[0022] The technical scope of the present invention is not limited to the content described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
