[0024] Furthermore, it should be understood that for ease of description, the sizes of the various components shown in the drawings are not drawn according to actual proportions. For example, the thickness or width of certain layers may be exaggerated relative to other layers.

[0025] It should be noted that like numbers and letters represent similar items in the following figures, so once an item is defined or described in one figure, it will not need to be further discussed and described in detail in the description of the subsequent figures.

[0026] In order to solve the technical problems in the background technology, such as Figure 1-4 As shown, the present application provides a technical solution: a new lightweight wheel hub with a temperature sensing device, which has the following characteristics:

[0027] The hub body 1 is made of high-strength aluminum alloy, offering excellent mechanical strength and lightweight properties. A concave reinforcement groove 2 is located in the center of the hub body 1, effectively enhancing its strength and rigidity. Furthermore, the hub body 1 is formed with rolled edges 3 on both sides, which contribute to the stability and safety of the hub. The spokes 4 are located within the hub body 1 and include herringbone-shaped reinforcement ribs 5 and a central bearing frame 6. Multiple herringbone-shaped reinforcement ribs 5 are evenly distributed throughout the hub body 1, effectively enhancing its strength and rigidity while reducing its overall weight. The central bearing frame 6 is located at the center of the spokes 4 and supports bearings and rotating components, ensuring the proper operation of the hub body 1. Ventilation holes 7 are distributed along the spokes 4, with one located between every two adjacent reinforcement ribs 5. These ventilation holes 7 enhance air circulation within the hub, reducing temperatures and extending its service life. The fixing ring 8 is arranged on the inner side of the hub body 1, and is used to fix and support the spokes 4 and the temperature sensing device 9. The design of the fixing ring 8 ensures the stability and safety of the overall structure of the hub. The temperature sensing device 9 includes a temperature sensor 10, a wireless signal transmitter 11 and a data cable 12. The temperature sensor 10 is attached to the hub body 1 and is used to monitor the temperature of the hub body 1 in real time. The temperature sensor 10 transmits the temperature information to the wireless signal transmitter 11 through the data cable 12, and the wireless signal transmitter 11 transmits the received information to the central processor in the cab. The data cable 12 connects the temperature sensor 10 and the wireless signal transmitter 11 for transmitting temperature information.

[0028] During use, a plurality of reinforcement rings 13 are designed, which are coaxially arranged with the wheel hub and are located around the wheel hub body 1. The reinforcement ring 13 is annular, with the inner side fitting tightly against the outer wall of the wheel hub body 1, and the outer side protruding outward to form a certain bulge. The design of the reinforcement ring 13 is intended to provide additional support and strength to improve the overall stability and durability of the wheel hub. The reinforcement ring 13 can be made of the same high-strength aluminum alloy material as the wheel hub body 1, or other lightweight and high-strength materials, such as carbon fiber composite materials, can be selected to further reduce the weight of the wheel hub. The reinforcement rings 13 are evenly distributed around the wheel hub body 1, and can be a continuous annular structure or a plurality of segmented small rings. The reinforcement ring 13 is fixed to the wheel hub body 1 by welding, riveting or integral molding to ensure that the connection between the reinforcement ring 13 and the wheel hub body 1 is firm and reliable.

[0029] It's worth noting that the curled edges 3, located on both sides of the hub body 1, curl toward the reinforcement groove 2 to form a hollow circle. This design not only enhances the hub's strength but also provides additional cushioning at low tire pressures, thereby improving driving comfort and hub durability.

[0030] Furthermore, a decorative light strip 14 is integrated around the perimeter of the fixing ring 8 and can utilize LED light strips, which are lightweight, durable, and have low energy consumption. The LED light strip can be designed in a variety of colors to enhance the aesthetics of the wheel hub and provide additional visual identification during nighttime driving. The light strip can be connected to a battery pack 15 (not shown in the figures) via a waterproof connector or welding to ensure a reliable electrical connection and waterproof performance. The battery pack 15 is housed within the fixing ring 8 and can be a compact, high-capacity lithium battery to provide sufficient energy for the decorative light strip 14. The battery pack 15 must be secured within the fixing ring 8 to prevent displacement or damage during vehicle operation. A dedicated bracket or adhesive can be used for securing the decorative light strip 14. The decorative light strip 14 can be controlled by the vehicle's central control system to achieve various lighting modes, such as steady on, flashing, or gradual changes. It can also be designed with an automatic sensing mode, automatically illuminating upon unlocking or locking the vehicle, enhancing vehicle safety and convenience. The specific design of the decorative light strip 14 is prior art and will not be described in detail here.

[0031] It should be noted that the reinforcing rib 5 is an important component of the spoke 4 and is used to improve the strength and rigidity of the hub. In this embodiment, the branch of the reinforcing rib 5 connecting to the center bearing frame 6 is thicker than the branch connecting to the hub body 1. Such a design can provide better support and load-bearing capacity. Generally, the branch connecting to the center bearing frame 6 needs to withstand greater bending moments and torques, so it is designed with a thicker cross-section to improve its strength and rigidity. The reinforcing rib 5 is subjected to greater forces at the branch connecting to the center bearing frame 6. Since the cross-sectional area of ​​the reinforcing rib 5 is larger, it can effectively resist the effects of these forces. At the same time, the reinforcing rib 5 is subjected to smaller forces at the branch connecting to the hub body 1, which helps to reduce the overall weight of the hub.

[0032] Furthermore, grooves 16 are provided in the branch connecting the reinforcing rib 5 to the center bearing frame 6. Grooves 16 can be longitudinal or transverse, with their specific shape and dimensions determined based on force analysis and structural optimization. The design of grooves 16 reduces material usage without compromising the strength and rigidity of the wheel hub, contributing to its lightweight design.

[0033] It's important to note that the widened portion 17 is located midway between the branch where the reinforcing rib 5 connects to the hub body 1. This design aims to enhance the hub's load-bearing capacity and stability by increasing strength in this localized area, particularly under high-load and high-speed driving conditions. The widened portion 17 effectively disperses the stress experienced by the hub during driving, reducing material fatigue and damage caused by concentrated stress. Furthermore, the widened portion 17 provides a larger connection surface for the reinforcing rib 5, strengthening its connection to the hub body 1 and thereby improving overall structural stability.

[0034] Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
