Abstract
Description
Technical Field
[0001] This application belongs to the field of electric vehicle accessories, specifically relating to a reflective wheel rim with side air valves. Background Technology
[0002] Electric bicycles, electric motorcycles, or electric tricycles are electrically powered tools for personal travel and short-distance transportation. The wheels of an electric vehicle are the only point of contact between the vehicle and the ground, serving as the foundation for load-bearing and movement, as well as the core components for power transmission, braking, and steering. The core structure of the wheel includes the rim, tire, bearing, spokes, and valve.
[0003] The wheel rim, also called the wheel hub, is the component on the periphery of the wheel that mounts and supports the tire. The wheel rim is a crucial component of electric vehicles. It serves as the base for tire assembly and fixation, providing a stable support structure that allows the tire to maintain a specific shape and position, ensuring good contact between the tire and the ground during vehicle operation. When the vehicle is in motion, the wheel rim must bear the weight of the vehicle itself, the weight of passengers and cargo, as well as various impacts, friction, and inertial forces generated during travel. These forces are transmitted to the wheel rim through the tire, and the wheel rim must possess sufficient strength and rigidity to withstand these loads to ensure safe vehicle operation. Currently, the valve position of the front wheel rim on existing electric vehicles is controlled by the spoke shape, and it is mounted face-up on the rim, meaning the valve is directly opposite the rim's central axis. The valve position restricts the spoke shape. Currently, most electric vehicles have reflectors mounted on the front fork riser tube or rear of the vehicle. At night, especially in environments without streetlights, these reflectors only alert the driver to vehicles directly in front or behind the vehicle. When an electric vehicle appears to the side or front of the vehicle, the reflectors fail to promptly alert the driver, posing a safety hazard. Utility Model Content
[0004] To address the problems existing in the prior art, this utility model provides a reflective wheel rim with a side air nozzle. The side of the wheel rim is punched to reduce the restriction of the air nozzle on the wheel spoke shape. At the same time, reflective surfaces are set on both sides of the wheel spoke to reduce safety accidents.
[0005] The technical solution adopted in this utility model is as follows:
[0006] A reflective wheel rim with a side air valve includes a rim body that matches the tire, a side air valve fixing hole on the rim body, a spoke fixed on the inner side of the rim body, a reflective surface arranged on the outer surface of the spoke, a mounting cylinder for mounting an axle at the center of the spoke, two bearings arranged at intervals inside the mounting cylinder, the inner ring of the bearings connected to the axle, and the two ends of the axle extending out of the bearings and connected to the front fork of the electric vehicle.
[0007] Furthermore, the wheel rim body has a circular ring structure, including a flat section connected to the spokes. On both sides of the flat section, a first conical section, a sloped section, and a second conical section are sequentially arranged outwards. A rounded corner is formed between the flat section and the first conical section to achieve a smooth transition. An upward-protruding annular peak is formed between the first conical section and the sloped section. This annular peak reduces stress concentration and increases wheel rim strength. The second conical section forms the rim flange of the wheel rim body. The outward extension length of the second conical section along the axis of the wheel rim body is less than the outward extension length of the first conical section along the axis of the wheel rim body. The outer periphery of the second conical section forms an inward-curved edge. This curled edge increases the tightness of contact between the wheel rim body and the tire, preventing tire detachment and providing higher safety performance.
[0008] Furthermore, the valve stem fixing hole is located on the first conical section of the wheel rim body. Since the first conical section is axially inclined relative to the wheel rim body, the valve stem fixing hole is obliquely arranged relative to the spokes, which does not restrict the spoke shape, expands the design space of the spokes, enhances the overall aesthetics of the wheel, and provides consumers with more choices.
[0009] Furthermore, the spokes include a spoke plate connected to the outer periphery of the wheel rim body and a spoke ring disposed on one side of the spoke plate and surrounding the mounting cylinder. The spoke plate is an annular plate, and the wall thickness of the spoke ring gradually increases towards the spoke plate, thereby improving the strength of the connection between the spoke plate and the spoke ring. The outer surfaces on both sides of the spoke plate form reflective surfaces. The reflective surfaces can be achieved by pasting reflective decals, or by controlling the roughness of the spoke plate through machining to achieve a reflective effect. For example, reflection can be achieved by machining and controlling the roughness to be below Ra3.2.
[0010] Furthermore, a support ring is provided around the periphery of the spoke. The support ring increases the contact area with the wheel rim body and improves the stability of the connection. The support ring and the spoke ring are located on different sides of the spoke.
[0011] Furthermore, the mounting cylinder extends through the center of the spoke, and the length of the mounting cylinder on the same side as the spoke ring is shorter than the length of the mounting cylinder on the other side. Preferably, the spoke and the mounting cylinder are integrally formed.
[0012] Furthermore, one side of the wheel spoke is provided with multiple threaded mounting posts arranged at intervals around the mounting cylinder. The threaded mounting posts are used to connect with the brake disc. A reinforcing ring is provided around the threaded mounting posts. Multiple first reinforcing ribs are provided between the mounting cylinder and the reinforcing ring in a radial pattern. The first reinforcing ribs are intersected with the threaded mounting posts. A second reinforcing rib is provided between the outer wall of the reinforcing ring and the wheel spoke. The first and second reinforcing ribs are used to enhance the strength of the entire wheel.
[0013] Furthermore, two bearings are respectively installed at both ends of the mounting cylinder, and the spaced-apart bearings improve the stability of the axle.
[0014] Furthermore, the material of the wheel rim body can be, for example, iron, to reduce the cost of the wheel rim while increasing its strength. The material of the spokes can be, for example, aluminum alloy, to reduce weight. The flat section of the wheel rim body and the support ring of the spokes can be welded together.
[0015] Furthermore, rubber rings are provided on the outer side of the bearings to protect them and provide waterproof and dustproof protection.
[0016] The beneficial effects of this utility model are:
[0017] This utility model provides a reflective wheel rim with a side air nozzle. The rim body includes a flat section, a first conical section, an inclined section, and a second conical section. The first conical section is axially inclined relative to the rim body. An air nozzle fixing hole is located on the first conical section of the rim body, and the fixing hole is obliquely arranged relative to the spokes, thus not restricting the spoke shape, expanding the design space for the spokes, enhancing the overall aesthetics of the wheel, and providing consumers with more choices. The spokes include spoke plates and spoke rings. The outer surfaces of both sides of the spoke plates form reflective surfaces, thereby alerting vehicles approaching from the side that an electric vehicle is approaching, allowing for timely handling and preventing accidents. A rolled edge on the outer periphery of the second conical section increases the tightness of contact between the rim body and the tire, preventing tire detachment. Support rings, reinforcing rings, a first reinforcing rib, and a second reinforcing rib are provided around the spoke plates to enhance the strength of the rim and spokes, preventing wheel deformation, improving the wheel's load-bearing capacity, and ensuring the safety of the electric vehicle under various driving conditions.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0030] like Figure 1-5As shown, a reflective wheel rim with a side air valve includes a wheel rim body 1 that matches the tire. The wheel rim body 1 has a side air valve fixing hole 2. A spoke 3 is fixed on the inner side of the wheel rim body 1. A reflective surface 4 is arranged on the outer surface of the spoke 3. A mounting cylinder 5 for mounting an axle is provided at the center of the spoke 3. Two bearings 6 are arranged at intervals inside the mounting cylinder 5. The inner ring of the bearing 6 is connected to the axle. The two ends of the axle extend out of the bearing 6 and are connected to the front fork of the electric vehicle.
[0031] like Figure 1 , Figure 4 , Figure 5 As shown, the wheel rim body 1 has a circular structure. The wheel rim body 1 includes a planar segment 101 connected to the spokes 3. On both sides of the planar segment 101, a first conical segment 102, a sloped segment 103, and a second conical segment 104 are sequentially arranged outwards from the periphery. A rounded corner is formed between the planar segment 101 and the first conical segment 102, achieving a smooth transition between them. An upwardly raised annular peak 105 is formed between the first conical segment 102 and the sloped segment 103. The annular convex peak 105 reduces stress concentration and increases rim strength. The second conical section 104 forms the rim of the rim body 1. The length of the second conical section 104 extending outward along the axis of the rim body 1 is less than the length of the first conical section 102 extending outward along the axis of the rim body 1. The outer periphery of the second conical section 104 forms an inward rolled edge 106. The rolled edge 106 increases the tightness of contact between the rim body 1 and the tire, preventing the tire from falling off and providing higher safety performance.
[0032] like Figure 1 , Figure 5 As shown, the valve stem fixing hole 2 is opened on the first conical section 102 of the wheel rim body 1. Since the first conical section 102 is axially inclined relative to the wheel rim body 1, the valve stem fixing hole 2 is obliquely arranged relative to the spokes 3, which does not restrict the shape of the spokes 3, expands the design space of the spokes 3, enhances the aesthetics of the entire wheel, and provides consumers with more choices.
[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the spoke 3 includes a spoke plate 301 connected to the outer periphery of the wheel rim body 1 and a spoke ring 302 disposed on one side of the spoke plate 301 and surrounding the mounting cylinder 5. The spoke plate 301 is an annular plate, and the spoke ring 302 is shaped like a volcano. The wall thickness of the spoke ring 302 gradually increases towards the spoke plate 301, thereby improving the connection strength between the spoke plate 301 and the spoke ring 302. Reflective surfaces 4 are formed on both sides of the spoke plate 301. The reflective surfaces 4 can be achieved by pasting reflective decals, or by controlling the roughness of the spoke plate 301 through machining to achieve a reflective effect. For example, reflection can be achieved by machining and controlling the roughness to be below Ra3.2.
[0034] like Figure 4 As shown, a support ring 304 is provided around the periphery of the spoke 301. The support ring 304 increases the contact area with the wheel rim body 1 and improves the stability of the connection. The support ring 304 and the spoke ring 302 are located on different sides of the spoke 301.
[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the mounting cylinder 5 passes through the center of the spoke 3. The length of the mounting cylinder 5 on the same side as the spoke ring 302 is shorter than the length of the mounting cylinder 5 on the other side. The spoke 3 is preferably integrally formed with the mounting cylinder 5.
[0036] like Figure 1 As shown, one side of the wheel spoke 3 is provided with a plurality of threaded mounting posts 7 arranged at intervals around the mounting cylinder 5. The threaded mounting posts 7 are used to connect with the brake disc. A reinforcing ring 8 is provided around the threaded mounting posts 7. A plurality of first reinforcing ribs 9 are provided between the mounting cylinder 5 and the reinforcing ring 8 in a radial pattern. The first reinforcing ribs 9 are intersected with the threaded mounting posts 7. A second reinforcing rib 10 is provided between the outer wall of the reinforcing ring 8 and the wheel spoke 3. The first reinforcing ribs 9 and the second reinforcing ribs 10 are used to enhance the strength of the entire wheel.
[0037] like Figure 4 As shown, two bearings 6 are respectively set at both ends of the mounting cylinder 5, and the two bearings 6 set at intervals improve the stability of the axle.
[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the material of the wheel rim body 1 can be, for example, iron, to reduce the cost of the wheel rim and increase its strength. The material of the spokes 3 can be, for example, aluminum alloy, to reduce weight. The flat section 101 of the wheel rim body 1 and the support ring 304 of the spokes 3 are welded and fixed, for example. Iron sheets are embedded in the outer periphery of the spokes 3 during die casting for welding connection with the wheel rim body 1.
[0039] like Figure 1 , Figure 2 , Figure 4 As shown, each bearing 6 is provided with a rubber ring 11 on its outer side to protect the bearing 6 and to provide waterproof and dustproof protection.
[0040] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
