Technical Field
[0001] This invention relates to the field of wheel hub technology, and in particular to a car wheel hub with an anti-theft mechanism. Background Technology
[0002] A car wheel hub is a component that supports the tire. Fastening bolts pass through the mounting surface at the end of the hub and are fixed to the car axle or body, thus connecting the hub to the axle or body. These bolts are usually exposed and can be removed and installed using a socket wrench. To prevent wheel hub theft or accidental loosening of bolts by unqualified personnel, special-shaped bolts and nuts are typically used for fastening, or concealing devices are installed. While special-shaped bolts and nuts achieve the purpose of theft prevention, they suffer from poor versatility and limited anti-theft methods. Although concealing devices can cover the bolts and nuts, they must be disassembled before repairing or replacing the wheel hub, making wheel hub disassembly and assembly inconvenient.

[0007] Preferably, an elastic structure is provided between the switching ring and the movable groove, so that the switching sleeve has a tendency to move away from the movable groove.
[0008] Preferably, the elastic structure includes at least two spring bodies, each of which is evenly distributed along the circumference of the switching ring.

[0016] Compared with the prior art, the beneficial effects of the present invention are:
[0017] 1. The present invention relates to a car wheel hub with an anti-theft mechanism, the anti-theft mechanism consisting of a flange and a movable plate. By changing the relative position of the flange and the movable plate, the anti-theft mechanism can be switched to an anti-theft state or an operating state. When the anti-theft mechanism is in the operating state, all fastening bolts are fully exposed, facilitating car maintenance. When the anti-theft mechanism is switched to the anti-theft state, the fastening bolts are partially covered by the movable plate. This car wheel hub effectively prevents non-professionals from arbitrarily disassembling the fastening bolts through the switching mechanism, thereby improving anti-theft security. The operation of switching the state of the anti-theft mechanism is convenient, facilitating the maintenance and replacement of the car wheel hub.
[0018] 2. During the process of switching the anti-theft mechanism from the anti-theft state to the operational state, the operator rotates the movable plate relative to the flange so that each movable hole corresponds to each movable slot. This allows the operator to insert a socket wrench into the switching sleeve and loosen the fastening bolts. The operator only needs to loosen one of the fastening bolts to move a part of the corresponding switching sleeve into the movable hole, thereby limiting the movable plate to maintain the operational state of the anti-theft mechanism. This allows the operator to disassemble the remaining fastening bolts without having to separate the movable plate of the anti-theft mechanism, thus enabling the disassembly of the car wheel hub and the car axle.
[0019] 3. During the process of switching the anti-theft mechanism from the operating state to the anti-theft state, the staff must tighten all the fastening bolts to ensure that all the switching sleeves are inserted into the movable slots and that all the switching sleeves are completely disengaged from the inner wall of the movable holes. At this time, the movable plate can rotate relative to the flange, thereby switching the anti-theft mechanism to the anti-theft state. This prevents the staff from missing any fastening bolts and improves the security of the car wheel hub. Attached Figure Description

[0028] The present invention will be further described below with reference to the embodiments and accompanying drawings.
[0029] refer to Figure 1 , Figure 2 , Figure 3 A car wheel hub with an anti-theft mechanism includes a wheel hub body 1, an anti-theft mechanism 2, and a special switching tool 8. The wheel hub body 1 includes a rim 11, a center disc 12, and several spokes 13. Each spoke 13 is evenly distributed around the circumference of the center disc 12 and fixedly connected to the rim 11. Five mounting sleeves 101 are fixedly connected to the center disc 12 and evenly arranged around its circumference. One end of each mounting sleeve 101 extends to the outer side wall of the center disc 12. A first centering hole 102 is provided through the center of the center disc 12, and a mounting ring 104 is also provided at the center of the center disc 12.
[0030] The anti-theft mechanism 2 includes a flange 21 and a movable plate 22. Both the flange 21 and the movable plate 22 are inserted into the mounting ring 104. A second centering hole 205 is passed through the center of the flange 21. The first centering hole 102 is adapted to and connected to the second centering hole 205. A rotating shaft 207 is provided at the center of the movable plate 22. The rotating shaft 207 is inserted into the second centering hole 205 and the first centering hole 102 in sequence, so that the center plate 12, the flange 21 and the movable plate 22 are arranged coaxially, and the movable plate 22 can rotate relative to the flange 21. The flange 21 and the movable plate 22 are in a contact fit or clearance fit. At least one guide component 7 is provided between the flange 21 and the movable plate 22. The guide component 7 includes a guide post 71 and a track groove 72 extending circumferentially along the movable plate 22. The guide post 71 is slidably disposed in the track groove 72 and is fixedly connected to the movable plate 22. The track groove 72 is opened on the flange 21, thereby guiding and restricting the rotation of the movable plate 22 relative to the flange 21.
[0031] The inner wall of the opening at the end of the first centering hole 102 away from the flange 21 has a mounting groove 103. One end of the rotating shaft 207 extends into the mounting groove 103 and is fitted with a limiting plate 208. The limiting plate 208 is bolted to one end of the rotating shaft 207. The limiting plate 208 is rotatably connected in the mounting groove 103 to prevent the movable plate 22 and the flange 21 from detaching from the center plate 12. The side wall of the limiting plate 208 away from the rotating shaft 207 cooperates with the side wall of the center plate 12 to prevent interference with the assembly of the car wheel hub and the car axle.
[0032] The flange 21 has five alignment holes 201 evenly arranged around its circumference, which are used for the insertion of the mounting sleeve 101 to position the flange 21 on the central plate 12. A movable groove 202 is formed on the inner wall of the opening of the alignment hole 201 away from the central plate 12. A movable hole 206, which is adapted to and communicates with the movable groove 202, is provided through the movable plate 22. The inner diameter of the movable hole 206 is the same as that of the central plate 12.
[0033] refer to Figure 2 , Figure 3 , Figure 6 , Figure 7 A switching sleeve 3 is slidably disposed in the movable groove 202. The outer wall of the switching sleeve 3 is provided with three guide parts 302 arranged in a ring array. The inner wall of the movable groove 202 is provided with a guide groove 203 for sliding engagement of the guide parts 302, thereby guiding and restricting the sliding of the switching sleeve 3. A switching ring 301 is formed on the side of the switching sleeve 3 near the mounting sleeve 101. The inner wall of the switching ring 301 is in contact engagement or clearance engagement with the outer wall of the mounting sleeve 101 to avoid the mounting sleeve 101 interfering with the axial translation of the switching sleeve 3.
[0034] The guide part 302 is a V-shaped elastic hook structure. The outer wall of the guide part 302 is inclined. The opening side of the movable groove 202 is provided with an inclined guide surface 204 relative to the guide groove 203. When the switching sleeve 3 is installed in the movable groove 202, the outer wall of the guide part 302 abuts against the guide surface 204 to guide the switching sleeve 3 to be aligned and inserted into the movable hole 206. At the same time, the guide part 302 is also driven to deform under pressure, so that the switching sleeve 3 can be smoothly inserted into the position until the guide part 302 is located in the guide groove 203. Then the guide part 302 returns to its original shape so that the wire part can enter the wire groove.
[0035] Mounting sleeve 101 is fitted with fastening bolt 4. The shank of fastening bolt 4 passes through mounting sleeve 101, extends to the outside of the intermediate disc, and is threadedly connected to the vehicle axle. The inner diameter of switching sleeve 3 is larger than the outer diameter of the head of fastening bolt 4. The head of fastening bolt 4 is located inside switching sleeve 3. A guide wall 303 is provided on the open side of switching sleeve 3. The guide wall 303 is tapered to facilitate the insertion of a socket wrench into switching sleeve 3. The socket of the socket wrench engages with the anti-rotation insert of the head of fastening bolt 4. The outer diameter of the head of fastening bolt 4 is larger than the inner diameter of switching ring 301. The head of fastening bolt 4 abuts against switching ring 301. When fastening bolt 4 is tightened, it drives switching sleeve 3 to move within movable groove 202 along the side closest to mounting sleeve 101.
[0036] refer to Figures 1 to 7 The anti-theft mechanism 2 of the car wheel hub consists of a flange 21 and a movable plate 22. By changing the relative position of the flange 21 and the movable plate 22, the anti-theft mechanism 2 can be switched to an anti-theft state or an operational state. When the anti-theft mechanism 2 is in the operational state, the outer wall of at least one switching sleeve 3 abuts against the inner wall of the movable hole 206, so that each movable hole 206 corresponds completely with each movable groove 202, and the heads of each fastening bolt 4 are fully exposed for easy vehicle maintenance. When the anti-theft mechanism 2 is switched to the anti-theft state, each switching sleeve 3 is completely detached from the inner wall of each movable hole 206, and the movable plate 22 can rotate relative to the flange 21, so that each movable hole 206 is at least partially misaligned with each movable groove 202, and at least a portion of the head of each fastening bolt 4 is blocked by the movable plate 22, thus achieving the anti-theft effect. The car wheel hub effectively prevents non-professionals from arbitrarily disassembling the fastening bolts 4 through a switching mechanism, thereby improving anti-theft security. The operation of the anti-theft mechanism 2 in switching states is convenient, making it easy to maintain and replace the car wheel hub.
[0037] When the anti-theft mechanism 2 is in operation, each movable hole 206 corresponds perfectly to each movable groove 202, and the heads of each fastening bolt 4 are fully exposed. When the fastening bolt 4 is not tightened, part of the switching sleeve 3 is located in the movable groove 202, and the other part of the switching sleeve 3 is located in the movable hole 206. The outer wall of the switching sleeve 3 abuts against the inner wall of the movable hole 206, and the switching sleeve 3 limits the movable plate 22, thereby maintaining the operation of the anti-theft mechanism 2, so that the staff can install or remove the car wheel hub and car axle. The head of the fastening bolt 4 abuts against the switching ring 301, so that the switching sleeve 3 moves horizontally as the fastening bolt 4 is tightened, until the fastening bolt 4... When tightened to the correct position, the switching sleeve 3 is completely misaligned with the movable hole 206, thereby releasing the limiting effect of the switching sleeve 3 on the movable plate 22. Only when all fastening bolts 4 are tightened and all switching sleeves 3 are completely misaligned with each movable hole 206 can the movable plate 22 rotate relative to the flange 21, so that each movable hole 206 is at least partially misaligned with each movable groove 202. At least a portion of the head of each fastening bolt 4 is blocked by the movable plate 22, which serves as an anti-theft measure. At the same time, it also makes it easier for workers to determine whether each fastening bolt 4 is tightened to the correct position when installing the car wheel hub and car axle, avoiding negligence by workers when installing or removing the car wheel hub.
[0038] During the process of switching the anti-theft mechanism 2 from the anti-theft state to the operating state, the operator drives the movable plate 22 to rotate relative to the flange 21, so that each movable hole 206 corresponds to each movable slot 202. This allows the operator to insert a socket wrench into the switching sleeve 3 and loosen the fastening bolt 4 by using the socket wrench. The operator only needs to loosen one of the fastening bolts 4 to move a part of the corresponding switching sleeve 3 into the movable hole 206, thereby limiting the movable plate 22 to maintain the operating state of the anti-theft mechanism 2. This allows the operator to disassemble the remaining fastening bolts 4 without having to disassemble the movable plate 22 of the anti-theft mechanism 2. This allows for the disassembly of the car wheel hub and the car axle.
[0039] During the process of switching the anti-theft mechanism 2 from the operating state to the anti-theft state, the staff needs to tighten all the fastening bolts 4 to ensure that all the switching sleeves 3 are inserted into the movable slots 202 and that all the switching sleeves 3 are completely disengaged from the inner walls of the movable holes 206. At this time, the movable plate 22 can rotate relative to the flange 21, thereby switching the anti-theft mechanism 2 to the anti-theft state. This prevents the staff from missing any fastening bolts 4 that are not tightened, thereby improving the security of the car wheel hub.
[0040] An elastic structure 5 is provided between the switching ring 301 and the movable groove 202. The elastic structure 5 includes three spring bodies 501. Each spring body 501 is evenly distributed along the circumference of the switching ring 301. One end of the spring body 501 is fixedly connected to the switching ring 301, and the other end of the spring body 501 abuts against the inner wall of the movable groove 202, so that the switching sleeve 3 has a tendency to move away from the movable groove 202. This ensures that when the operator uses a socket wrench to loosen the fastening bolt 4, the switching sleeve 3 can be translated and reset by the elastic structure 5, so that the outer wall of the switching sleeve 3 abuts against the inner wall of the movable hole 206, thereby realizing that the anti-theft mechanism 2 maintains its operating state after the fastening bolt 4 is loosened.
[0041] The limiting plate 208 and the mounting groove 103 are spaced apart. A coil spring 6 is provided between the limiting plate 208 and the mounting groove 103. The outer end of the coil spring 6 is fixed to the limiting plate 208, and the inner end of the coil spring 6 is fixed to the mounting groove 103. Under the action of the coil spring 6, the movable plate 22 has a tendency to rotate relative to the flange 21. When each fastening bolt 4 is tightened to the correct position, each switching sleeve 3 releases the limiting position on the movable plate 22. At this time, the coil spring 6 restores its deformation to drive the movable plate 22 to rotate, so that the anti-theft mechanism 2 has a tendency to switch from the operating state to the anti-theft state, and realizes that the anti-theft mechanism 2 automatically switches to the anti-theft state after each fastening bolt 4 is tightened to the correct position.
[0042] refer to Figure 2 , Figure 4 , Figure 5The special switching tool 8 includes an operating handle 81 and an operating structure 82 fixedly connected to the operating handle 81. The operating structure 82 has three operating heads 801. The operator can hold the operating handle 81 to operate the special switching tool 8, so that each operating head 801 is inserted into the corresponding movable hole 206, driving the movable plate 22 to rotate relative to the flange 21, thereby switching the anti-theft mechanism 2 to the operating state, so that the fastening bolt 4 in the movable hole 206 that was not inserted by the operating head 801 is fully exposed. Then, the operator only needs to operate the socket wrench to pass through the movable hole 206 and insert it into the switching sleeve 3, so that the socket of the socket wrench cooperates with the anti-rotation sleeve of the head of the fastening bolt 4, thereby unscrewing the fastening bolt 4, releasing the head of the fastening bolt 4 from the limiting position of the switching ring 301, and the switching ring... The elastic structure 5 on 301 resets to move the switching sleeve 3 away from the movable slot 202 until the outer wall of the switching sleeve 3 abuts against the inner wall of the movable hole 206. At this point, the switching sleeve 3 limits the movable plate 22, and the operator no longer needs to operate the special switching tool 8. Afterward, the operator can unscrew the other fastening bolts 4 in sequence to complete the disassembly of the car wheel hub. Similarly, when the car wheel hub is installed on the car axle, the operator can rotate the movable plate 22 by operating the special switching tool 8 so that each movable hole 206 corresponds to each movable slot 202. The switching sleeve 3 is reset by the driving force of the elastic structure 5 returning to its original position so that the switching sleeve 3 is inserted into the corresponding movable hole 206. The outer wall of the switching sleeve 3 abuts against the inner wall of the movable hole 206, thereby maintaining the operation of the anti-theft mechanism 2.
[0043] Of course, the above are just typical examples of the present invention. In addition, the present invention may have many other specific embodiments. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.
