[0002] In the field of hub motors, brakes and brake assemblies are often used for braking. During the operation of hub motors, brakes and brake assemblies are often equipped to ensure that they can stop safely and stably. However, traditional hub motor brake assemblies do not have independent heat dissipation structures, which leads to unstable braking effect due to the inability to dissipate heat in time during braking. With frequent use, performance is prone to decline, which not only affects the normal operation of hub motors and increases safety hazards, but also increases maintenance costs due to frequent repairs and replacements, thereby reducing the service life of the equipment. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a hub motor electric brake and electromagnetic brake assembly, which solves the technical problem that traditional hub motor brake assemblies in the prior art do not have an independent heat dissipation structure.

[0004] The purpose and effect of this utility model of a hub motor electric brake and electromagnetic brake assembly are achieved by the following specific technical means:

[0005] An electric brake and electromagnetic brake assembly for a hub motor includes a first housing and a second housing. The first housing is installed below the hub motor, and the second housing is installed below the first housing. One end of the hub motor is secured within the first housing. A locking block and a first brake disc are disposed below the hub motor. A fixing block is disposed below the locking block. A fixing groove is formed on the first brake disc, and the fixing block is secured within the fixing groove. A pressure plate is installed below the first brake disc. A support sleeve is secured within the second housing. A fan blade is disposed below the support sleeve, and a braking assembly is disposed above it. A rotating block and a connecting block are disposed within the support sleeve.

[0006] According to a preferred embodiment, the support sleeve has a rotating hole, the rotating block is engaged in the rotating hole, the rotating block has a limiting hole, the limiting hole is hexagonal, the connecting block is engaged in the limiting hole, and the connecting block and the rotating block are detachably connected; the connecting block has a connecting hole, and the lower shaft end of the hub motor is engaged in the connecting hole.

[0007] According to a preferred embodiment, the bottom of the rotating block passes through the support sleeve and is secured inside the fan blade, and the support sleeve has a heat dissipation grille above the fan blade.

[0008] According to a preferred embodiment, the braking assembly includes a spring and an electromagnetic coil, a limit ring is provided inside the support sleeve, the spring is sleeved on the outer wall of the limit ring, and the electromagnetic coil is engaged inside the limit ring.

[0009] According to a preferred embodiment, the braking assembly further includes a second brake disc, which is disposed above the electromagnetic coil, and a limit block is disposed below the second brake disc, the limit block being engaged within the support sleeve.

[0010] According to a preferred embodiment, mesh protrusions are provided below the first brake disc and above the second brake disc, and heat dissipation fins are provided above the first brake disc.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model, through the arrangement of the braking assembly, utilizes the coordinated action of the spring, electromagnetic coil, first brake disc, and second brake disc. When braking is required, the electromagnetic coil loses power and magnetic force, causing the spring to push the second brake disc, which, in conjunction with the first brake disc, effectively brakes the hub motor, thus improving the braking performance of the assembly. Furthermore, the mesh protrusions on the first and second brake discs increase friction, enabling the assembly to provide more reliable braking force during braking, thereby enhancing its braking reliability.

[0014] 2. When using this component, the user can connect the hub motor shaft end to the connecting block, enabling the hub motor to stably drive the fan blades to rotate. The airflow generated by the fan blade rotation further enhances the heat dissipation effect, allowing the user to better ensure the component's heat dissipation needs during operation and improving the component's heat dissipation efficiency. Simultaneously, the ventilation grilles on the outer walls of the first and second housings also contribute to the overall ventilation and heat dissipation of the component, further optimizing its heat dissipation performance.

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0025] Example:

[0026] like Figures 1 to 7 As shown, this utility model provides a hub motor electric brake and electromagnetic brake assembly, comprising a first housing 11 and a second housing 12 forming the main frame. The first housing 11 is installed below the hub motor 13, providing partial support and protection for the assembly. The second housing 12 is installed below the first housing 11, further improving the assembly structure. One end of the hub motor 13 is inserted into the first housing 11. Below the hub motor 13, a locking block 14 and a first brake disc 15 are provided. A fixing block is connected below the locking block 14. A fixing groove is formed on the first brake disc 15, and the fixing block is inserted into the fixing groove to fix the first brake disc 15 below the hub motor 13. A pressure plate 16 is installed below the first brake disc 15, which provides a certain degree of stability to the first brake disc 15. A support sleeve 17 is installed inside the second housing 12, which plays a key role in supporting and connecting other components in the assembly. A fan blade 18 is installed below the support sleeve 17, and a braking component is installed above it. Meanwhile, a rotating block 19 and a connecting block 21 are installed inside the support sleeve 17. These components work together to achieve the heat dissipation function of the component.

[0027] like Figures 2 to 4 , Figure 6 , Figure 7As shown, the support sleeve 17 has a rotating hole 22, and the rotating block 19 is fitted into the rotating hole 22 and can rotate within it. The rotating block 19 has a limiting hole 23, which is hexagonal. The connecting block 21 is fitted into the limiting hole 23, and the connecting block 21 and the rotating block 19 are detachably connected, facilitating component replacement or maintenance when needed. It can also be replaced according to different hub motor 13 shaft ends, increasing the flexibility and adaptability of the entire assembly and meeting diverse application requirements. The connecting block 21 has a connecting hole, and the lower shaft end of the hub motor 13 is fitted into the connecting hole. This connection method allows the rotation of the hub motor 13 to be transmitted to the rotating block 19.

[0028] The bottom of the rotating block 19 passes through the support sleeve 17 and is engaged inside the fan blade 18. When the hub motor 13 rotates, it drives the rotating block 19, which in turn drives the fan blade 18 to rotate. The support sleeve 17 has a heat dissipation grille above the fan blade 18. When the fan blade 18 rotates, it can accelerate the airflow and carry away the heat generated inside the braking assembly through the heat dissipation grille, effectively reducing the component temperature and ensuring its stable operation.

[0029] The braking assembly includes a spring 24 and an electromagnetic coil 25. A limiting ring 26 is provided inside the support sleeve 17, the spring 24 is sleeved on the outer wall of the limiting ring 26, and the electromagnetic coil 25 is held inside the limiting ring 26. When the electromagnetic coil 25 is energized, it generates a magnetic field, which interacts with other components. When de-energized, it achieves the braking function, and the spring 24 plays a resetting role during the braking process.

[0030] The braking assembly also includes a second brake disc 27, which is positioned above the electromagnetic coil 25. A limiting block 28 is provided below the second brake disc 27, which engages with the support sleeve 17 to fix the position of the second brake disc 27 and restrict its rotation, so that the second brake disc 27 can work stably during braking and work in conjunction with other braking components to achieve the braking effect.

[0031] Mesh protrusions are provided below the first brake disc 15 and above the second brake disc 27. These protrusions increase the friction between the brake discs and improve the braking effect. Cooling fins are provided above the first brake disc 15 to further enhance its heat dissipation capacity and prevent it from overheating during braking, thus affecting its performance.

[0032] like Figures 2 to 4As shown, the locking block 14 is fitted onto the lower shaft end of the hub motor 13, causing the first brake disc 15 to rotate synchronously with the hub motor 13. The pressure plate 16 is connected to the locking block 14 by bolts, which securely connects the pressure plate 16 to the hub motor 13. Multiple sets of ventilation grilles are provided on the outer walls of both the first housing 11 and the second housing 12, which further promotes the circulation of air between the inside and outside of the component, enhances heat dissipation, and ensures the normal operation of the component under various working conditions.

[0033] The specific usage and function of this embodiment are as follows:

[0034] When using the hub motor electric brake and electromagnetic brake assembly, the hub motor 13 rotates, driving the connecting block 21 and rotating block 19 to rotate, which in turn causes the fan blades 18 to rotate, dissipating heat through the heat dissipation grille. When braking is required, the electromagnetic coil 25 loses power and its magnetic field, releasing the second brake disc 27. The spring 24 pushes the second brake disc 27 to move stably under the restriction of the limiting block 28, interacting with the first brake disc 15. The first brake disc 15 is connected to the hub motor 13 through the locking block 14 and the fixing block, and its lower mesh protrusions contact the upper mesh protrusions of the second brake disc 27, increasing friction to achieve braking. At the same time, the heat dissipation fins of the first brake disc 15 and the ventilation grille on the outer shell continuously dissipate the heat generated by braking, ensuring that the assembly can stably and reliably complete the braking operation and ensuring the safe operation of the hub motor.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
