Description

Technical Field

[0001] This utility model belongs to the field of braking technology, specifically relating to brake devices and electromagnetic braking systems. Background Technology

[0002] A braking structure is a mechanical braking device that slows down a vehicle; it is also known as a speed reducer. Current braking structures primarily use mechanical brakes. However, with the development of drone technology, more and more drones are appearing in our lives, and drones are evolving towards ultra-high speed, high maneuverability, lightweight design, miniaturization, and low cost.

[0003] However, traditional hydraulic and pneumatic brakes have disadvantages such as being heavy, bulky, and costly to maintain. In particular, the wear and tear on the brake pads cannot be detected in time, leading to a gradual decrease in braking performance and affecting the responsiveness of stopping.

[0004] In view of the above factors, a braking device and an electromagnetic braking system are provided to adjust the distance between the brake pads and the brake disc, which are fixedly installed by the fixing block, so that the distance that the worn brake pads travel to brake the brake disc is the same as the distance that the intact brake pads travel to brake the brake disc. This improves the braking stability of the electromagnetic braking device, extends the service life of the brake pads, and reduces accidents caused by brake failure due to brake pad wear. Utility Model Content

[0005] The purpose of this invention is to provide a braking device and an electromagnetic braking system to solve the problems mentioned in the background art.

[0006] The purpose of this utility model is achieved through the following technical solution: a brake device, including a brake disc and a brake caliper bracket, with brake pads provided on both sides of the brake disc, two thickness sensors fixedly installed on the brake caliper bracket, an electromagnetic device provided on one side of each of the two thickness sensors, and multiple spring plates fixedly connected between the electromagnetic device and the iron core inserted thereon, with a position control structure installed on each of the two iron cores, and the two position control structures respectively provided on both sides of the brake disc, the position control structure being used to control the position of the brake pads on the same side;

[0007] The iron core is fixedly connected to the outer wall of the pneumatic cylinder. The pneumatic cylinder pushes the electromagnet, iron plate, and fixed block to move, adjusting the distance between the brake pads and brake disc fixedly installed on the fixed block, so that the distance the worn brake pads travel to brake the brake disc is the same as the distance the intact brake pads travel to brake the brake disc.

[0008] Furthermore, the position control structure includes an installation groove at one end of the iron core and a fixing block disposed inside the installation groove, one end of the fixing block being fixedly connected to the brake pad.

[0009] The position control structure also includes multiple mounting shafts provided at the bottom of the fixed block, both ends of the multiple mounting shafts are fixedly connected to the iron core, and gear components are sleeved on the outer side of the multiple mounting shafts;

[0010] Multiple one-way bearings are fixedly connected between the gear component and the mounting shaft. The bottom of the fixing block is provided with tooth grooves, and the multiple gear components are in a meshing state with the fixing block through the tooth grooves.

[0011] Furthermore, a magnet is fixedly sleeved on the outside of the plurality of one-way bearings. The magnet is disposed inside the gear component, and the outer wall of the magnet is in contact with the inside of the gear component. The magnet attracts and fixes the iron gear component by magnetic force, so that the gear component rotates after being subjected to force. The arrangement of multiple magnets and multiple one-way bearings enables the gear component to rotate in one direction after being subjected to force, thereby limiting the position of the fixing block.

[0012] Furthermore, the top of the fixing block is provided with multiple support frames, and the end of the support frame near the brake pad is provided with a hexagonal groove. The support frame is internally threaded with bolts, and one end of the bolts is fixedly connected to the iron core.

[0013] The mounting shaft and gear components block the downward movement of the fixing block. The two sides of the fixing block are in contact with the iron core 5. The fixing block is blocked from the top and bottom by multiple support frames and multiple gear components.

[0014] Furthermore, a reserved groove is provided at the end of the fixing block away from the brake pad, and an iron plate is provided inside the reserved groove. The iron plate is fixedly connected to the fixing block, and an electromagnet is provided on the side of the iron plate away from the brake pad. A pneumatic cylinder is fixedly connected to one end of the electromagnet, and the outer wall of the pneumatic cylinder is fixedly connected to the iron core.

[0015] Furthermore, both of the electromagnetic devices are fixedly mounted on the brake caliper bracket, which is U-shaped, and the brake disc is provided with multiple heat dissipation holes;

[0016] Side grooves are provided on both sides of the bottom of the fixed block, and side plates are provided inside the side grooves. One end of the side plate is fixedly connected to the iron core, and the side plate limits the maximum movement distance of the fixed block.

[0017] An electromagnetic braking system for a braking device, wherein a thickness sensor is electrically connected to the electromagnetic braking system, the electromagnetic braking system includes a displacement sensor, the displacement sensor is electrically connected to a braking data calculation module, the braking data calculation module is electrically connected to a data feedback module, a current control module and a wear calculation module, the wear calculation module is electrically connected to a displacement calculation module, and the displacement calculation module is electrically connected to a control module.

[0018] The thickness sensor detects the thickness of the brake pads, and the detection result is fed back to the electromagnetic braking system of the vehicle. Based on the thickness of the worn brake pads, the electromagnetic braking system controls the pneumatic cylinder in the corresponding position control structure to work. The pneumatic cylinder pushes the electromagnet, the iron plate, and the fixed block to move, adjusting the distance between the brake pads fixedly mounted on the fixed block and the brake disc, so that the distance the worn brake pads travel to brake the brake disc is the same as the distance the intact brake pads travel to brake the brake disc.

[0019] Furthermore, in the electromagnetic braking system, the displacement sensor acquires the distance traveled by the driver when pressing the brake pedal, and the braking data calculation module converts it into current calculation parameters. The current control module, which is electrically connected to the braking data calculation module, controls the power supply from the vehicle's electrical system to the electromagnetic device according to the current calculation parameters, controls the thrust applied by the electromagnetic device to the iron core, and controls the friction between the brake pads and the brake disc.

[0020] A method for applying an electromagnetic braking system in a braking device includes a thickness sensor detecting the wear thickness and feeding it back to the electrically connected electromagnetic braking system. A data feedback module in the electromagnetic braking system receives the feedback data and converts it into calculation parameters. The data feedback module then outputs these calculation parameters to a braking data calculation module. The braking data calculation module calculates the brake pad wear thickness data based on the calculation parameters. Simultaneously, the data feedback module obtains braking speed data of the brake disc after wear and before wear from the vehicle system, using the same current parameters. The braking data calculation module then calculates the braking speed of the brake disc when the brake pads are not worn. The braking efficiency reduction ratio of the brake pads is compared with the first comparison parameter. The wear thickness data and the first comparison parameter are sent to the wear calculation module connected to the brake stop data calculation module. The wear calculation module calculates the impact parameter of the brake pad wear thickness on the vehicle braking. When the impact parameter is greater than the preset value, the displacement calculation module calculates the brake pad movement distance based on the brake pad wear thickness. The control module controls the air cylinder and electromagnet to perform corresponding work based on the calculation results of the displacement calculation module, controls the relative distance between the brake pad and the iron core, automatically adjusts the brake pad position, and supplements the brake pad wear thickness to ensure the braking effect of the brake disc.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] This invention uses a timed control system to operate two thickness sensors. The thickness sensors detect the thickness of the brake pads, and the detection results are fed back to the electromagnetic braking system on the vehicle. Based on the thickness of the worn brake pads, the electromagnetic braking system controls the operation of the pneumatic cylinder in the corresponding position control structure. The pneumatic cylinder pushes the electromagnet, iron plate, and fixed block to move, adjusting the distance between the brake pads and the brake disc fixed by the fixed block. This ensures that the distance the worn brake pads travel to brake the brake disc is the same as the distance a healthy brake pad travels to brake the brake disc, improving the stability of the electromagnetic braking device, extending the service life of the brake pads, and reducing accidents caused by brake failure due to brake pad wear.

[0023] In this utility model, multiple one-way bearings that can only rotate in one direction are fixedly connected between the gear components and the mounting shaft. Since the bottom of the fixed block has a toothed groove, and the multiple gear components are meshed with the fixed block through the corresponding toothed grooves, the mounting shaft and gear components block the downward movement of the fixed block. Since the two sides of the fixed block are in contact with the iron core, and the fixed block is blocked from the top and bottom by multiple support frames and multiple gear components, the fixed block can only move horizontally under the action of the pneumatic cylinder, ensuring the stability of the fixed block in supporting the brake pads.

[0024] In this invention, wear thickness data and comparison parameters are transmitted from the brake stop data calculation module to the electrically connected wear calculation module. The wear calculation module calculates the influence parameters of brake pad wear thickness on vehicle braking. When the influence parameters are greater than the preset values, the displacement calculation module calculates the brake pad movement distance based on the brake pad wear thickness. The control module controls the pneumatic cylinder and electromagnet to perform corresponding operations based on the calculation results of the displacement calculation module, controls the relative distance between the brake pad and the iron core, automatically adjusts the brake pad position, and supplements the brake pad wear thickness to ensure the braking effect of the brake disc.

Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0036] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0038] like Figure 1-9 As shown, the braking device includes a brake disc 1 and a brake caliper bracket 3. Brake pads 8 are provided on both sides of the brake disc 1. Two thickness sensors 22 are fixedly installed on the brake caliper bracket 3. An electromagnetic device 4 is provided on one side of each of the two thickness sensors 22. Multiple spring plates 25 are fixedly connected between the electromagnetic device 4 and the iron core 5 inserted on it. A position control structure is installed on each of the two iron cores 5. The two position control structures are respectively provided on both sides of the brake disc 1. The position control structure is used to control the position of the brake pads 8 on the same side.

[0039] The iron core 5 is fixedly connected to the outer wall of the pneumatic cylinder 18. The pneumatic cylinder 18 pushes the electromagnet, the iron plate 16, and the fixing block 7 to move, adjusting the distance between the brake pad 8 fixedly installed on the fixing block and the brake disc 1, so that the distance the worn brake pad moves to brake the brake disc 1 is the same as the distance the intact brake pad moves to brake the brake disc.

[0040] Specifically, the electromagnetic braking device, composed of a brake disc 1, brake caliper bracket 3, two brake pads 8, two electromagnetic devices 4, two position control structures, and two iron cores 5, operates on the following principle:

[0041] A U-shaped brake caliper bracket 3 is fitted onto the outside of the brake disc 1. Electromagnetic devices 4 are fixedly connected to both ends of the brake caliper bracket 3, and the two electromagnetic devices 4 are symmetrically arranged on both sides of the brake disc 1. Figure 1 As shown, when the brake disc 1 needs to be stopped, the control electromagnetic device 4 is activated. Since an iron core 5 is inserted inside the electromagnetic device 4, the electromagnetic module inside the electromagnetic device 4 generates magnetic force to push the iron core 5, causing the iron core 5 to push the brake pad 8 towards the brake disc 1 and make it fit against the brake disc 1. Under the action of friction between the brake disc 1 and the brake pad 8, the brake disc 1 is stopped. The electromagnetic device 4 is directly driven by electricity as the braking power, which reduces the space occupied by the brake structure, has good braking stability, and is less prone to failures such as oil leakage and increased oil impurities affecting stability that occur in traditional hydraulic power brakes.

[0042] When the electromagnetic device 4 stops working, the spring plate 25, which is fixedly connected between the iron core 5 and the electromagnetic device 4, contracts and drives the iron core 5 to reset. Since the iron core 5 has a limited range of motion at one end of the electromagnetic device 4, although the elastic spring plate 25 drives the iron core 5 to reset, the iron core 5 and the brake plate 8 still reset to their initial state.

[0043] Two thickness sensors 22 are fixedly installed on the upper brake caliper bracket 3. After the two brake pads 8 return to their initial positions, the two brake pads 8 are respectively on the detection paths of the two thickness sensors 22. The two thickness sensors 22 are controlled to work at regular intervals. The thickness sensors 22 detect the thickness of the brake pads 8. The detection results of the thickness sensors 22 are fed back to the electromagnetic braking system of the vehicle's upper brake. The electromagnetic braking system of the brake controls the corresponding position control structure to work according to the thickness of the worn brake pads 8.

[0044] In the position control structure, the mounting slot 6 is located at one end of the iron core 5, and one end of the fixing block 7 inside the mounting slot 6 is fixedly connected to the brake pad 8, so that the brake pad 8 and the iron core 5 are in a movable installation state. A reserved slot 15 is provided at the end of the fixing block 7 away from the brake pad 8. An iron plate 16 is fixedly connected to the fixing block 7 inside the reserved slot 15. The iron plate 16 is made of iron material and can be attracted by magnetic force. An electromagnet 17 is provided on the side of the iron plate 16 away from the brake pad 8. The outer wall of the pneumatic cylinder 18 is fixedly connected to the iron core 5. The electromagnetic braking system of the brake controls the pneumatic cylinder 18 to work and extend a certain distance according to the thickness of the worn brake pad 8, and the electromagnet 17 is in working state after the vehicle is started. In the vehicle's motion, the electromagnet 17 operates and is magnetically attracted and fixed to the iron plate 16, causing the fixing block 7 and the pneumatic cylinder 18 to move synchronously. The relative position between the brake pad 8 fixed by the fixing block 7 and the iron core 5 on which the pneumatic cylinder 18 is installed remains unchanged. After the pneumatic cylinder 18 operates, it pushes the electromagnet 17, the iron plate 16, and the fixing block 7 to move, adjusting the distance between the brake pad 8 fixed by the fixing block 7 and the brake disc 1. This ensures that the distance the worn brake pad 8 travels to brake the brake disc 1 is the same as the distance the intact brake pad 8 travels to brake the brake disc 1, improving the stability of the electromagnetic braking device, extending the service life of the brake pad 8, and reducing accidents caused by brake failure due to brake pad wear.

[0045] Multiple support frames 19 are provided on the top of the fixed block 7. Bolts 20 are threaded inside the support frames 19, and one end of the bolts 20 is fixedly connected to the iron core 5. Therefore, the iron core 5 is equipped with multiple support frames 19 by multiple bolts 20. The multiple support frames 19 are in line contact with the top of the fixed block 7, which limits the upward movement of the fixed block 7. Multiple mounting shafts 10 are provided at the bottom of the fixed block 7. Both ends of the multiple mounting shafts 10 are fixedly connected to the iron core 5. The mounting shafts 10 cannot rotate. Gear components 12 are sleeved on the outside of the multiple mounting shafts 10. Multiple one-way bearings 11 that can only rotate in one direction are fixedly connected between the mounting shaft 10 and the mounting shaft 2. Since the bottom of the fixing block 7 has a toothed groove 9 and multiple gear components 12 are meshed with the fixing block 7 through the corresponding toothed groove 9, the mounting shaft 10 and gear components 12 block the downward movement of the fixing block 7. Since the two sides of the fixing block 7 are in contact with the iron core 5, the fixing block 7 is blocked from the top and bottom by multiple support frames 19 and multiple gear components 12. Therefore, the fixing block 7 can only move horizontally under the action of the pneumatic cylinder 18, ensuring the stability of the fixing block 7 in supporting the brake pad 8.

[0046] Since the inner and outer rings of the one-way bearing 11 can only rotate in one direction, and the inner ring of the one-way bearing 11 is fixedly connected to the mounting shaft 10, while the outer ring of the one-way bearing 11 is fixedly installed inside the gear component 12, the gear component 12 can only rotate in one direction outside the mounting shaft 10. When the fixed block 7 is pushed by the pneumatic cylinder 18, the fixed block 7 drives the meshing gear component 12 to rotate in the direction of the one-way bearing 11's rotation. The fixed block 7 can drive the brake pad 8 to move, adjusting the relative position between the brake pad 8 and the iron core 5. When the electromagnetic device 4 works to push the iron core 5 to move, causing the brake pad 8 to fit against the brake disc 1, the force transmission direction between the fixed block 7 and the gear component 12 is the self-locking direction of the one-way bearing 11. Therefore, when the electromagnetic device 4 works to control the brake pad 8 to brake the brake disc 1, the relative position between the fixed block 7 and the iron core 5 will not change under the limitation of the pneumatic cylinder 18 and multiple gear components 12. The multiple gear components 12 share the force on the pneumatic cylinder 18, slowing down the damage rate of the pneumatic cylinder 18.

[0047] Magnets 24 are fixedly sleeved on the outside of multiple one-way bearings 11. The outer wall of the magnets 24 is in contact with the inside of the gear 12. The magnets 24 attract and fix the iron gear 12 with magnetic force, so that the gear 12 can only rotate after being subjected to a certain force. The arrangement of multiple magnets 24 and multiple one-way bearings 11 ensures that the gear 12 can only rotate in one direction after being subjected to a certain force, and limits the fixed block 7. Even after the vehicle is closed, the fixed block 7 is still limited and cannot move, thus avoiding the situation where the fixed block 7 moves due to vehicle vibration, which would affect the working stability of the electromagnetic braking device.

[0048] When the brake pad 8 needs to be replaced, a hexagonal groove 21 is provided at one end of the multiple support brackets 19 near the brake pad 8. Using a hexagonal wrench matching the hexagonal groove 21, the support bracket 19 is rotated to move away from the outside of the bolt 20. Then, the pneumatic cylinder 18 is extended to its limit, at which point the fixing block 7 is pushed to its limit. At this point, the multiple gear components 12 are in the same state as when one end of the fixing block 7 is inserted into the mounting groove 6 and engages with the iron core 5. Furthermore, under the action of the magnet 24, the gear components 12 will not rotate due to the operation of the iron core 5. Then, the support bracket 19 is retracted. Since the electromagnet 17 is not working, the pneumatic cylinder 18 cannot drive the fixing block 7 to reset. Without the support frame 19 blocking the upper part of the fixed block 7, after moving the fixed block 7 and brake pad 8 upwards, the fixed block 7 can be pulled out of the mounting slot 6, and the fixed block 7 and brake pad 8 can be removed. Then, the new fixed block 7 is inserted into the mounting slot 6. Since the reserved slot 15 is set as a reserved space for the electromagnet 17 and the pneumatic cylinder 18, the electromagnet 17 and the pneumatic cylinder 18 will not affect the insertion of the fixed block 7. When one end of the fixed block 7 is in contact with the iron core 5, the fixed block 7 is moved down so that the multiple toothed grooves 9 opened at the bottom of the fixed block 7 mesh with the multiple gear parts 12. At this time, the iron plate 16 is in contact with the electromagnet 17. Then, the support frame 19 is rotated and installed on the outside of the bolt 20, and the installation of the new brake pad 8 and the fixed block 7 with the iron core 5 is completed.

[0049] Multiple heat dissipation holes 23 are provided on the brake disc 1 for heat dissipation. Side grooves 13 are provided on both sides of the bottom of the fixing block 7. One end of the side plate 14 provided inside the side groove 13 is fixedly connected to the iron core 5. The side plate 14 limits the maximum movement distance of the fixing block 7 to prevent the fixing block 7 from going out of control.

[0050] A method for applying an electromagnetic braking system in a braking device is disclosed. During operation, a thickness sensor 22 detects and feeds back the results to an electrically connected electromagnetic braking system 2. A data feedback module 202 in the electromagnetic braking system 2 receives the feedback data and converts it into calculation parameters. The data feedback module 202 then outputs these calculation parameters to a braking data calculation module 203. The braking data calculation module 203 calculates the wear thickness data of the brake pad 8 based on the calculation parameters. Simultaneously, the data feedback module 202 obtains braking speed data of the brake disc 1 after wear and before wear of the brake pad 8 from the vehicle system, along with braking speed data of the brake disc 1 when the brake pad 8 is not worn. The braking data calculation module 203 calculates the braking efficiency reduction ratio of the brake pad 8 using a comparison parameter. The wear thickness data and the comparison parameter are then processed by the braking data calculation module 203. The data is transmitted to the wear calculation module 204, which is electrically connected. The wear calculation module 204 calculates the influence parameters of the wear thickness of the brake pad 8 on the vehicle's braking. When the influence parameters are greater than the preset values, the displacement calculation module 205 calculates the movement distance of the brake pad 8 based on the wear thickness of the brake pad 8. The control module 207 (which uses an AT89C51 microcontroller with built-in A / D conversion in the central processing unit; the braking data calculation module, wear calculation module, displacement calculation module, data feedback module, and current control module are existing modular structures, and the selection of models is not described here; the selection of the above modules only needs to achieve the function of electrical connection) controls the pneumatic cylinder 18 and electromagnet 17 to perform corresponding operations based on the calculation results of the displacement calculation module 205, controls the relative distance between the brake pad 8 and the iron core 5, automatically adjusts the position of the brake pad 8, and supplements the wear thickness of the brake pad 8 to ensure the braking effect of the brake disc 1.

[0051] In the electromagnetic braking system 2, the displacement sensor 201 acquires the distance the driver moves when pressing the brake pedal. The braking data calculation module 203 converts this into current calculation parameters. The current control module 206, which is electrically connected to the braking data calculation module 203, controls the power supply from the vehicle's electrical system to the electromagnetic device 4 based on the current calculation parameters. It also controls the thrust applied by the electromagnetic device 4 to the iron core 5 and controls the friction between the brake pads 8 and the brake disc 1.

[0052] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0053] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
