[0030] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0031] The following is for reference. Figures 1-6 Describes a vehicle 100 according to an embodiment of the present utility model.

[0032] Combination Figures 1-5 As shown, the vehicle 100 according to this utility model may mainly include: brake disc 20, brake backplate 10 and generator 30.

[0033] The brake disc 20 is adapted to be fixedly connected to the wheel hub of the vehicle and rotate synchronously with the wheel hub. The brake backing plate 10 is spaced apart on the circumferential outer side of the brake disc 20. The brake backing plate 10 is adapted to be fixedly connected to the steering knuckle 50 of the vehicle or the axle housing of the vehicle. The brake disc 20 is rotatably arranged relative to the brake backing plate 10.

[0034] Specifically, the vehicle 100 is equipped with a chassis, which supports and secures various key components of the vehicle 100 and ensures the rigidity and stability of the overall structure of the vehicle 100. The chassis is equipped with an axle and a steering knuckle 50. The axle may include an axle housing and an axle, with the axle at least partially mounted on the axle housing. A wheel hub is located at the end of the axle, and the wheel hub can be further fixedly connected to the wheel, thereby ensuring the transmission of power between the axle and the wheel. Furthermore, the steering knuckle 50 is rotatably connected to the wheel hub, so that without affecting the normal rotation of the wheel, the steering knuckle 50 can achieve multiple functions such as steering, load-bearing, and stability, ensuring the normal operation of the vehicle 100.

[0035] Furthermore, the brake disc 20 is fixedly connected to the wheel hub, allowing the brake disc 20 to rotate synchronously with the wheel hub and even the wheel. By fixing the brake caliper 60 to the axle housing or steering knuckle 50, the brake caliper 60 is positioned on the circumferential outer side of the brake disc 20. This allows the brake caliper 60 to be fixedly set relative to the brake disc 20. When the user has a braking need, the brake caliper 60 can be controlled to clamp the brake disc 20 to achieve braking of the wheel. When the user no longer needs braking, the brake caliper 60 can be controlled to release the brake disc 20, ensuring the normal rotation of the wheel.

[0036] Furthermore, the brake backing plate 10 is fixedly connected to the steering knuckle 50 or axle housing of the vehicle 100. The brake backing plate 10 is spaced out on the circumferential outer side of the brake disc 20. The brake disc 20 can rotate relative to the brake backing plate 10. The brake backing plate 10 can block external mud and water from the brake disc 20, ensuring the normal operation of the brake disc 20.

[0037] It should be noted that the chassis can have at least two axles, with the steering knuckle 50 connected to the wheel hub of at least one axle. When the axle is connected to the steering knuckle 50, both the brake caliper 60 and the brake backing plate 10 are connected to the steering knuckle 50. When the axle is not connected to the steering knuckle 50, both the brake caliper 60 and the brake backing plate 10 are connected to the axle housing. This allows for the fixed installation of the brake caliper 60 and the brake backing plate 10.

[0038] Furthermore, the generator 30 may include a stator 31 and a rotor 32. The stator 31 is fixedly disposed on the side of the brake backplate 10 facing the brake disc 20, and the rotor 32 is fixedly disposed on the outer periphery of the brake disc 20 and spaced apart from the stator 31. One of the stator 31 and the rotor 32 includes a permanent magnet 33, which forms a magnetic field. The other of the stator 31 and the rotor 32 includes a winding 34, which selectively cuts the magnetic induction lines of the magnetic field.

[0039] Specifically, by fixing the stator 31 to the brake backplate 10 so that the stator 31 faces the brake disc 20, and setting the rotor 32 on the outer periphery of the brake disc 20, the rotor 32 can rotate synchronously with the brake disc 20. The rotor 32 and the stator 31 are spaced apart. In this way, without affecting the normal operation of the brake disc 20, the original structure of the vehicle 100 can be fully utilized to realize the setting of the generator 30. When the vehicle 100 is driving normally and the wheels drive the brake disc 20 to rotate, the relative movement between the stator 31 and the rotor 32 can be realized.

[0040] By including a permanent magnet 33 in one of the stator 31 and the rotor 32, which can generate a magnetic field, and including a winding 34 in the other of the stator 31 and the rotor 32, when relative motion occurs between the stator 31 and the rotor 32, the winding 34 can cut the magnetic field lines of the magnetic field, thereby generating an electromotive force in the winding 34, and then generating a current, realizing the conversion of mechanical energy into electrical energy. This enables the recovery of vehicle energy to power other electrical components of the vehicle 100, making the vehicle 100 more energy-efficient and environmentally friendly, and enhancing the product competitiveness of the vehicle 100.

[0041] Thus, by fixing the stator 31 to the brake backplate 10 and fixing the rotor 32 to the outer periphery of the brake disc 20 and spaced apart from the stator 31, and by making one of the stator 31 and the rotor 32 include a permanent magnet 33 and the other of the stator 31 and the rotor 32 include a winding 34, the vehicle 100 can use the rotation of the wheels to make the winding 34 cut the magnetic induction lines of the magnetic field, converting mechanical energy into electrical energy, thereby realizing energy recovery and reuse.

[0042] In some embodiments of this utility model, combined with Figures 1-4 as well as Figure 6 As shown, there are multiple permanent magnets 33, the rotor 32 may include multiple permanent magnets 33, and the stator 31 may include windings 34.

[0043] Specifically, combined Figures 1-3 As shown, multiple permanent magnets 33 are arranged circumferentially around the outer periphery of the brake disc 20, and the magnetization directions of the multiple permanent magnets 33 are the same and parallel to the axial direction of the brake disc 20.

[0044] Specifically, the rotor 32 can include multiple permanent magnets 33, which are spaced apart circumferentially on the outer periphery of the brake disc 20. This creates a uniform magnetic field around the brake disc 20, allowing the magnetic field to rotate when the brake disc 20 rotates, while the winding 34 remains fixed. In other words, the winding 34 can rotate relative to the magnetic field, cutting magnetic lines of force to generate electricity and ensuring the normal operation of the generator 30. Preferably, the multiple permanent magnets 33 are evenly spaced circumferentially on the outer periphery of the brake disc 20.

[0045] Furthermore, the magnetization directions of the multiple permanent magnets 33 are the same and parallel to the axial direction of the brake disc 20. In this way, the multiple permanent magnets 33 can form a magnetic field in the axial direction, ensuring the uniformity of the magnetic field. Furthermore, it can ensure that the magnetic field generated by the multiple permanent magnets 33 is effectively transmitted to the winding 34, ensuring that the winding 34 cuts the magnetic field when the brake disc 20 rotates, thereby ensuring the normal operation of the vehicle 100 and ensuring power generation efficiency.

[0046] Combination Figures 1-3 As shown, the brake disc 20 is provided with multiple fins 22, which are spaced apart in the circumferential direction. A ventilation channel 21 is formed between two adjacent fins 22, and multiple permanent magnets 33 are correspondingly arranged at the outer end of the ventilation channel 21.

[0047] Specifically, to improve the heat dissipation efficiency of the brake disc 20, reduce its operating temperature, and ensure its performance, multiple fins 22 can be provided inside the brake disc 20, and these fins 22 can be spaced apart in the circumferential direction, with ventilation channels 21 forming between adjacent fins 22. It is understood that the multiple ventilation channels 21, spaced apart in the circumferential direction, allow air to flow through the ventilation channels 21 and carry away heat when the brake disc 20 rotates.

[0048] In this application, by correspondingly arranging multiple permanent magnets 33 in multiple ventilation channels 21 and positioning the permanent magnets 33 at the outer end of the ventilation channel 21, the structure of the ventilation channel 21 can be fully utilized. Without affecting the operation of the brake disc 20, the arrangement of the rotor 32 can be made simpler and more convenient, and the structure of the vehicle 100 can be made simpler and more reliable.

[0049] It should be noted that the dimensions of the permanent magnet 33 and the ventilation channel 21 can be designed to ensure that the permanent magnet 33 will not block the ventilation channel 21 after it is placed in the ventilation channel 21, thus ensuring the ventilation and heat dissipation performance of the brake disc 20.

[0050] Multiple permanent magnets 33 can be attached to multiple ventilation ducts 21, or an installation groove can be provided on the outer side of the ventilation duct 21, and multiple permanent magnets 33 can be placed in the installation groove. Other fixing methods are also possible, and no specific restrictions are made here.

[0051] Combination Figures 1-5 As shown, the brake backplate 10 has a plurality of winding teeth 11 on the side facing the brake disc 20. The plurality of winding teeth 11 are spaced apart in the circumferential direction, and the winding 34 is wound around the plurality of winding teeth 11.

[0052] Specifically, by providing multiple winding teeth 11 on the side of the brake backplate 10 facing the brake disc 20, and by arranging the multiple winding teeth 11 at intervals in the circumferential direction, the winding 34 is wound around the winding teeth 11. This makes full use of the structure of the brake backplate 10, so that the brake backplate 10 can provide support for the winding 34 and achieve stable setting of the winding 34.

[0053] Furthermore, the winding teeth 11 are made of stacked silicon steel sheets. This gives the winding teeth 11 not only good magnetic permeability, providing a low magnetic resistance path for the magnetic field, thus more effectively conducting the magnetic field, enhancing magnetic flux, and reducing hysteresis, but also effectively reducing the size of eddy currents and the energy loss they cause, thereby improving the efficiency of the vehicle 100. In addition, considering that silicon steel sheets can be stamped into the required shape and then stacked together to form a complex iron core structure, this facilitates the manufacturing of the winding teeth 11 and even the brake backing plate 10, ensuring the precision of the brake backing plate 10.

[0054] In some other embodiments of this utility model, there are multiple permanent magnets 33, the stator 31 may include multiple permanent magnets 33, and the rotor 32 may include windings 34.

[0055] Specifically, a plurality of permanent magnets 33 are circumferentially spaced on the side of the brake backplate 10 facing the brake disc 20, and the magnetization directions of the plurality of permanent magnets 33 are the same and parallel to the axial direction of the brake backplate 10.

[0056] Specifically, the stator 31 can include multiple permanent magnets 33, and the multiple permanent magnets 33 can be evenly spaced around the brake back plate 10. In this way, the multiple permanent magnets 33 can form a uniform magnetic field near the brake back plate 120. When the brake disc 20 rotates, the winding 34 can rotate while the magnetic field remains fixed. That is, the winding 34 rotates relative to the magnetic field. The winding 34 can cut the magnetic field lines in the magnetic field to generate electrical energy, ensuring the normal operation of the generator 30.

[0057] Furthermore, the magnetization directions of the multiple permanent magnets 33 are the same and parallel to the axial direction of the brake backplate 10. In this way, the multiple permanent magnets 33 can form a magnetic field in the axial direction, ensuring the uniformity of the magnetic field. Furthermore, it can ensure that the magnetic field generated by the multiple permanent magnets 33 is effectively transmitted to the winding 34, ensuring that the winding 34 cuts the magnetic field when the brake disc 20 rotates, thereby ensuring the normal operation of the vehicle 100 and ensuring power generation efficiency.

[0058] Multiple permanent magnets 33 can be attached to the brake backplate 10, or mounting grooves can be provided on the brake backplate 10 to place multiple permanent magnets 33 in the mounting grooves, or other fixing methods can be used, which are not specifically limited here.

[0059] Furthermore, the brake disc 20 is provided with multiple fins 22, which are spaced apart in the circumferential direction, and a ventilation channel 21 is formed between two adjacent fins 22. The winding 34 is wound around the multiple fins 22.

[0060] Specifically, to improve the heat dissipation efficiency of the brake disc 20, reduce its operating temperature, and ensure its performance, multiple fins 22 can be provided inside the brake disc 20, and these fins 22 can be spaced apart in the circumferential direction, thus forming ventilation channels 21 between adjacent fins 22. It is understood that with multiple ventilation channels 21 spaced apart in the circumferential direction, air can flow through the ventilation channels 21 and carry away heat when the brake disc 20 rotates.

[0061] By winding the winding 34 around multiple fins 22, the structure of the brake disc 20 can be fully utilized, allowing the brake disc 20 to provide support for the winding 34 and achieve stable installation of the winding 34. It should be noted that the dimensions of the winding 34 and the ventilation channel 21 can be designed to ensure that the winding 34 does not block the ventilation channel 21 after being wound around multiple fins 22, thus ensuring the ventilation and heat dissipation performance of the brake disc 20.

[0062] Combination Figure 6 As shown, winding 34 is a three-phase winding. Specifically, winding 34 can be set as a three-phase winding, which not only provides more efficient power transmission and reduces energy loss, but also improves the stability, reliability, and starting performance of vehicle 100. Optionally, a copper wire can be wound around every two winding teeth 11, or every two fins 22, to achieve the three-phase winding configuration, which will not be elaborated here.

[0063] Combination Figure 6As shown, the vehicle 100 may further include a rectifier 40, which is electrically connected to the winding 34 to convert the generated alternating current (AC) into direct current (DC). Specifically, it can be understood that when the vehicle is moving and rotating the brake disc 20, the generator 30 can convert mechanical energy into electrical energy, and this electrical energy is alternating current (AC). Considering that the vehicle primarily uses DC power, to meet the power supply needs of other electrical components in the vehicle, the rectifier 40 can be electrically connected to the winding 34. In this way, the rectifier 40 can convert the AC power generated by the winding 34 into DC power, thereby facilitating the use of the vehicle's electrical components and ensuring the normal operation of the vehicle.
