[0032] The hub power generation device 1 according to an embodiment of the present utility model is described below with reference to the accompanying drawings.

[0033] like Figures 1 - 3 As shown, the wheel hub power generation device 1 according to the embodiment of the present utility model includes a wheel hub 100 and a motor assembly 200 .

[0034] The motor assembly 200 includes a motor housing and a generator 210. The generator 210 is mounted on the motor housing through a connecting plate 10. The wheel hub 100 is connected to the generator 210 through a pulley mechanism 300. The rotation of the wheel hub 100 drives the generator 210 to rotate so that the motor assembly 200 generates electricity. The connecting plate 10 is configured with an adjustment hole 11. The extension path of the adjustment hole 11 is configured as a straight line or a curve. The adjustment hole 11 is penetrated with a fastener 20 to mount the generator 210 on the motor housing.

[0035] For example, when the vehicle is traveling, the wheel hub 100 rotates, driving the generator 210 of the motor assembly 200 to rotate accordingly, thereby driving the rotor of the engine 210 to operate, thereby generating electricity and charging the battery pack.

[0036] According to the wheel hub generator 1 of the embodiment of the utility model, the outer wall of the connecting plate 10 is provided with an adjustment hole 11, and the generator 210 is fixed on the connecting plate 10 by the fastener 20 penetrating the adjustment hole 11. Since the extension path of the adjustment hole 11 of the connecting plate 10 can be a straight line or a curve, the fastener 20 can slide along the path in the adjustment hole 11 so as to change its fixed position, and the generator 210 will also move with the movement of the fastener 20. And due to the existence of the adjustment hole 11, the operator can quickly adjust the position of the fastener on the connecting plate 10 according to actual needs, and the staff does not need to disassemble the wheel hub 100 as a whole. It only needs to change the position of the engine 210 to replace the pulley mechanism 300, and quickly complete the maintenance work, which improves the convenience of device disassembly, shortens the maintenance time and improves efficiency.

[0037] In addition, the structure of the adjustment hole 11 makes the installation process easier, without replacing the connecting plate 10 or adding or removing parts. The generator 210 can be easily connected to the motor housing by simply adjusting the position of the fastener, and ensuring that the connection is firm and reliable.

[0038] Therefore, for the hub power generation device 1 according to the embodiments of the present invention, the adjustable function is added to the motor assembly 200, thereby improving the convenience of device disassembly.

[0039] In some specific embodiments of the present invention, as Figure 1 shown, the belt pulley mechanism 300 includes a driving pulley 340, a driven pulley 310, and a belt 320. The driving pulley 340 is connected to the hub 100. The driven pulley 310 is connected to the generator 210. The belt 320 is respectively in driving connection with the driving pulley 340 and the driven pulley 310. Specifically, the driving pulley 340 and the driven pulley 310 can both be belt pulleys. The driving pulley 340 and the driven pulley 310 are connected by the belt 320. When the driving pulley 340 rotates, it drives the driven pulley 310 to rotate through the belt 320.

[0040] The driving pulley 340 is connected to the hub 100 and is the core component that drives the entire device to operate. The driving pulley 340 is connected to an engine or other power source to provide power, drive the belt 320 to rotate, and thus drive the driven pulley 310 and the generator 210 to work. The rotational speed and performance of the driving pulley 340 directly affect the output power and efficiency of the hub power generation device 1. The driven pulley 310 is connected to the generator 210, receives the power transmitted by the driving pulley 340, and converts it into mechanical energy to drive the generator 210 to generate electricity. The structure of the driven pulley 310 and the connection method with the generator 210 directly affect the rotational speed of the generator 210 and the efficiency of electricity generation. The belt 320, as a transmission component between the driving pulley 340 and the driven pulley 310, plays a role in transmitting power. The driving pulley 340 drives the belt 320 to rotate, and then transmits it to the driven pulley 310 through the belt 320, thereby realizing energy conversion and power generation. The belt 320 usually has certain elasticity and wear resistance and can withstand a certain amount of tension and torque.

[0041] In some specific embodiments of the present invention, as Figure 2 and Figure 3 shown, the generator 210 and the driven pulley 310 are respectively located on both sides of the thickness direction of the connecting plate 10. The generator 210 is connected to the driven pulley 310 through a rotating shaft passing through the connecting plate 10. By connecting the generator 210 to the driven pulley 310 through the rotating shaft passing through the connecting plate 10, a complex transmission structure is avoided, and the overall structure of the hub power generation device 1 is simplified. This simple structure is not only easy to install and maintain but also can improve the stability and reliability of the hub power generation device 1.

[0042] In some specific embodiments of the present invention, as Figure 2 and Figure 3As shown in the figure, the connecting plate 10 is configured with an avoidance hole 12 through which the rotating shaft passes. The extending path of the avoidance hole 12 is the same as that of the adjustment hole 11. Among them, the size of the extending path of the avoidance hole 12 is larger than that of the adjustment hole 11. The same extending paths of the avoidance hole 12 and the adjustment hole 11 mean that whether adjusting the position of the generator 210 or other positions, the adjustment is carried out along the same path. By flexibly adjusting the installation positions of the fasteners and the generator 210, the disassembly and maintenance of the belt 320 are made more convenient and efficient. In addition, due to the relatively large volume of the generator 210, the size of the extending path of the avoidance hole 12 is larger, and they can cooperate well when adjusting the position of the generator 210, improving the reliability of the hub power generation device 1.

[0043] In some specific embodiments of the present invention, as Figure 1 shown in the figure, the diameter of the driving wheel 340 is larger than that of the driven wheel 310. For example, when driving at a low speed, the larger driving wheel 340 can ensure that the driven wheel 310 obtains sufficient torque, thus maintaining a stable power generation capacity. When driving at a high speed, although the rotational speed of the driven wheel 310 is relatively high, due to the larger diameter of the driving wheel 340, it can still maintain a relatively high torque to ensure the stable operation of the generator 210.

[0044] The fact that the diameter of the driving wheel 340 is larger than that of the driven wheel 310 means that the circumference of the driving wheel 340 is longer. When the driving wheel 340 drives the driven wheel 310 to rotate, due to the difference in circumference, the driving wheel 340 will apply a greater moment to the driven wheel 310, which can increase the torque output by the hub power generation device 1 and improve the power generation efficiency. The larger diameter of the driving wheel 340 and the smaller diameter of the driven wheel 310 result in different speed ratios in the energy transfer process of the hub power generation device 1. This difference can improve the transmission efficiency and reduce energy loss. By optimizing the distribution of torque and speed, the hub power generation device 1 can more effectively convert rotational motion into electrical energy.

[0045] In some specific embodiments of the present invention, as Figure 3 shown in the figure, there are multiple adjustment holes 11 distributed on both sides of the generator 210. Installation ears 211 extending outward are configured on both sides of the generator 210, and the installation ears 211 correspond to the adjustment holes 11 in position to jointly pass through fasteners. The installation ears 211 are of an "L" - shaped structure and are symmetrically arranged with respect to the central axis of the generator 210. One side of the installation ear 211 is connected to the connecting plate 10 through a fastener, and the other side is connected to the generator 210.

[0046] The mounting ears 211 extend out from both sides of the generator 210 in an "L" shape. By corresponding to the position of the adjustment holes 11, it ensures the stable installation of the generator 210 on the connecting plate 10. The mounting ears 211 are connected to the generator 210 and the connecting plate 10 by passing through fasteners together, providing reliable support and preventing the motor assembly 200 from shaking or loosening during use. At the same time, the adjustment holes 11 are distributed on both sides of the generator 210. By corresponding the mounting ears 211 to the positions of the adjustment holes, the generator 210 can be supported evenly, dispersing the pressure at the fixing points and avoiding stress concentration at one position, thus improving the structural stability and reliability of the hub power generation device 1.

[0047] In some specific embodiments of the present invention, as Figures 1 - 3 shown, multiple adjustment holes 11 are all configured as oblong holes and their extending paths are parallel to each other. Through the structure of the adjustment holes 11, the positions of components such as the generator 210 and the driven wheel 310 can be flexibly adjusted along the extending paths. Since the extending paths are parallel to each other, the position adjustment can be carried out in the same direction to ensure good alignment and balance among the components.

[0048] In some specific embodiments of the present invention, as Figure 1 shown, the belt pulley mechanism 300 further includes a tensioning device 330. The tensioning device 330 is installed on the connecting plate 10 and presses the belt 320. The tensioning device 330 installed on the connecting plate 10 serves to press the belt 320. By adjusting the tensioning device 330, the belt 320 can be effectively maintained at an appropriate tension, ensuring that the belt 320 does not become loose or slip during operation, and improving the transmission efficiency. At the same time, an appropriate tension force can reduce the friction between the belt 320 and the hub 100, reducing the wear degree of the belt 320. The presence of the tensioning device 330 can effectively extend the service life of the belt 320 and other transmission components, reduce the frequency of maintenance and replacement, and lower the maintenance cost.

[0049] The belt 320 is an important transmission component in the hub power generation device 1. Maintaining the appropriate tension of the belt 320 can make the transmission effect more stable. By adjusting the tension of the belt 320 through the tensioning device 330, the loss during energy transfer can be minimized, and the transmission efficiency can be improved. Keeping the belt 330 working within the specified tension range can effectively improve the power generation performance of the hub power generation device 1.

[0050] In some specific embodiments of the present invention, as Figure 1As shown, the hub power generation device 1 further includes a protective frame 400. The protective frame 400 is installed on the connecting plate 10, and the protective frame 400 partially surrounds the driving wheel 340 and the belt 320. The protective frame 400 can effectively enclose the driving wheel 340 and the belt 320 to form a protective barrier, preventing external objects from accidentally entering the device and avoiding accidents and injuries. Through the structure of the protective frame 400, the safety of the operator can be guaranteed to a certain extent. At the same time, the setting of the protective frame 400 can prevent the belt 320 from running off during operation, ensuring that the belt 320 stably transmits energy between the driving wheel 340 and the driven wheel 310. The fixing effect of the protective frame 400 helps to maintain the normal operation state of the hub power generation device 1. In addition, the coverage of the protective frame 400 can, to a certain extent, prevent impurities such as dust and foreign objects from entering components such as the driving wheel 340 and the belt, reducing problems such as dust accumulation and pollution, and is beneficial to keeping the hub power generation device 1 clean and operating normally.
