[0030] Schematic anti-theft wheel hub,

[0031] refer to Figures 2 to 7 According to a preferred embodiment of the utility model, an anti-theft wheel hub includes a wheel hub body 10 and an anti-theft component 20.

[0032] Specifically, Figure 3 As shown, the hub body 10 has a plurality of bolt holes 101 arranged in a circular array. In the embodiment of the present application, the number of the bolt holes 101 is six.

[0033] In addition, if Figure 2 and Figure 3 As shown, the anti-theft component 20 includes a plurality of baffles 201, which are rotatably mounted on the hub body 10. When the baffles 201 rotate at a predetermined angle, the baffles 201 block the bolt holes 101 or expose the bolt holes 101. In the embodiment of the present application, there are two baffles 201, both of which are semicircular ring-shaped. More specifically, each of the baffles 201 has a semicircular notch 2011, and each of the baffles 201 blocks or exposes three of the bolt holes 101.

[0034] It should be noted that, under normal circumstances, the two blocking pieces 201 block the bolts on the corresponding bolt holes 101, so that other people cannot screw the bolts, thereby achieving the technical purpose of anti-theft; when the anti-theft wheel hub needs to be removed, the blocking piece 201 is first rotated, and the blocking piece 201 no longer blocks the bolts on the corresponding bolt holes 101, so as to facilitate screwing of the bolts, thereby achieving maintenance and disassembly. It is obvious that compared with the prior art in which the bolts on the bolt holes 101 are normally exposed and easy to be screwed and the wheel hub is stolen, the embodiment of the present application has the advantage of selectively blocking the bolts.

[0035] Furthermore, in order to realize that the blocking piece 201 is locked and blocks the bolts on the corresponding bolt holes 101 under normal conditions, as shown in FIG. Figure 4 , Figure 5 and Figure 6 As shown, the anti-theft wheel hub also includes a locking assembly 30, which includes a lock core 301 and a plurality of lock tongues 302. Each of the baffles 201 has a limiting protrusion 2012 on a side close to the bolt hole 101, and each of the limiting protrusions 2012 has a limiting hole 2013. The lock tongues 302 correspond to the limiting holes 2013 one by one. When the lock core 301 is actuated, each of the lock tongues 302 is inserted into or disengaged from the corresponding limiting hole 2013.

[0036] It should be noted that when the lock tongue 302 is inserted into the corresponding limiting hole 2013, the baffle 201 is arranged horizontally and cannot rotate. At this time, the baffle 201 blocks the bolt on the bolt hole 101 to achieve anti-theft; when the lock tongue 302 is separated from the corresponding limiting hole 2013, the rotation of the baffle 201 is no longer restricted, and the baffle 201 can rotate around the rotation connection between the baffle 201 and the hub body 10, and expose the bolt on the bolt hole 101, so as to facilitate the disassembly of the anti-theft hub. In addition, since the lock core 301 is mature in technology and widely used in the market, the internal structure and model of the lock core 301 are not described here. The lock core 301 includes but is not limited to the lock core that can be rotated after the corresponding key is inserted as disclosed in the patent document (CN201723016U).

[0037] Furthermore, in order to realize that the baffle 201 is rotatably mounted on the hub body 10, as shown in FIG. Figure 2 As shown, the hub body 10 has a central hole 102. Figure 4 and Figure 5As shown, the anti-theft component 20 further includes two bases 202, which are respectively located on both sides of the center hole 102 and are symmetrically arranged, each of the bases 202 is fixedly connected to the hub body 10, and the fixed connection method includes but is not limited to welding or bolt connection, and the two ends of each baffle 201 are respectively rotatably connected to the two bases 202, and the two baffles 201 are symmetrically arranged. In addition, when the lock tongue 302 is inserted into the corresponding limiting hole 2013, the semicircular notch 2011 is directly opposite to the center hole 102.

[0038] Furthermore, if Figure 6 and Figure 7 As shown, each of the bases 202 is provided with a locking assembly 30, the lock core 301 is rotatably mounted on the base 202 through a bearing, the number of the lock tongues 302 is two, the lock core 301 is located between the two lock tongues 302, the two lock tongues 302 are slidably arranged on the base 202, a first magnet 3021 is provided at one end of the two lock tongues 302 facing each other, and two symmetrically arranged second magnets 3011 are provided at one end of the lock core 301 close to the lock tongue 302, the magnetic properties of the first magnet 3021 and the second magnet 3011 are opposite, and when the lock core 301 is rotated by a predetermined angle, each of the second magnets 3011 is arranged parallel to or vertically with the corresponding first magnet 3021.

[0039] It should be noted that the second magnet 3011 is a strip plate, and the magnetic poles are evenly distributed up and down. Now, assuming that the magnetic pole from the top surface of the second magnet 3011 to the center plane is the N pole, the magnetic pole from the bottom surface of the second magnet 3011 to the center plane is the S pole. Assuming that the side of the first magnet 3021 that is away from the corresponding lock tongue 302 is the S pole, when the second magnet 3011 is parallel to the first magnet 3021, that is, the top surface of the second magnet 3011 is arranged in parallel with the side of the first magnet 3021 that is away from the lock tongue 302, then under the action of the magnetic force, the lock tongue 302 slides toward the lock core 301 and disengages from the corresponding limiting hole 2013. At this time, the blocking piece 201 can be rotated and the bolt of the bolt hole 101 can be screwed; when the second magnet 3011 is arranged vertically with the first magnet 3021, the two end faces of the second magnet 3011 face the side of the first magnet 3021 away from the lock tongue 302. Since the magnetic poles of the second magnet 3011 are evenly distributed up and down, the two end faces of the second magnet 3011 have N poles and S poles, so it is difficult for this magnet to drive the lock tongue 302 to move toward the lock core 301. It should be pointed out that in this state, the lock tongue 302 is inserted into the corresponding limiting hole 2013, and the blocking piece 201 blocks the bolt on the bolt hole 101.

[0040] Specifically, in order to realize that the locking tongue 302 is inserted into the corresponding limiting hole 2013 under normal conditions, as shown in FIG. Figure 6 As shown, the base 202 has a rotating hole 2021 and a sliding cavity 2022, the rotating hole 2021 and the sliding cavity 2022 are arranged vertically and connected to each other, the lock core 301 is rotatably installed in the rotating hole 2021, the two lock tongues 302 are slidably set at the two ends of the sliding cavity 2022, and the sliding cavity 2022 also has two blocking edges 2023. In the embodiment of the present application, the blocking edge 2023 is in a circle, and the blocking edge 2023 and the cavity wall of the sliding cavity 2022 are made of insulating materials such as plastic or insulating paint is applied on the blocking edge 2023 and the cavity wall of the sliding cavity 2022. The lock core 301 is located between the two blocking edges 2023, and each of the locking components 30 also includes two elastic members 303, and the two ends of the elastic member 303 are respectively connected to the corresponding blocking edge 2023 and the lock tongue 302, and the connection method includes but is not limited to welding.

[0041] It should be noted that the second magnet 3011 and the first magnet 3021 are normally arranged vertically. Under the elastic force of the elastic member 303, the lock tongue 302 is normally inserted into the corresponding limiting hole 2013, so that the blocking piece 201 is normally locked to be horizontally arranged and blocks the bolt on the bolt hole 101; when the anti-theft wheel hub needs to be replaced, the car owner can insert the key into the lock core 301 and rotate it 90°. The lock core 301 drives the second magnet 3011 to rotate 90° and makes the second magnet 3011 and the first magnet 3021 arranged in parallel. At this time, the magnetic force is greater than the elastic force of the elastic member 303, and the lock tongue 302 moves toward the lock core 301 and disengages from the limiting hole 2013. At this time, the blocking piece 201 can rotate to facilitate unscrewing the bolt on the bolt hole 101.

[0042] Furthermore, when the two baffles 201 are flipped at an obtuse angle toward the center plane direction of the base 202, that is, one baffle 201 is flipped in the counterclockwise direction and the other baffle 201 is flipped in the clockwise direction, the two baffles 201 and the base 202 form an acute triangle as a whole to prevent the baffles 201 from falling under the action of their own weight when the bolts on the bolt holes 101 are screwed. Figure 2 As shown, each of the baffles 201 is provided with a third magnet 2014. When the two baffles 201 are flipped at an obtuse angle toward the central plane direction of the base 202, the two third magnets 2014 approach each other and provide an adsorbing magnetic force, so that the two baffles 201 and the base 202 maintain an acute triangle arrangement as a whole.

[0043] Furthermore, to facilitate heat dissipation of the external brake disc, e.g. Figure 2 As shown, the hub body 10 has a plurality of heat dissipation holes 103 arranged in a ring shape, and the heat dissipation holes 103 are located outside the central hole 102 .

[0044] In summary, the anti-theft wheel hub according to the embodiment of the present application is explained, which provides the anti-theft wheel hub with advantages such as selectively blocking bolts.

[0045] It is worth mentioning that in the embodiment of the present application, the anti-theft wheel hub has a simple structure, does not involve complex manufacturing processes and expensive materials, and has high economic efficiency. At the same time, for manufacturers, the anti-theft wheel hub provided by the present application is easy to produce and has low cost, which is more conducive to controlling production costs and further facilitating product promotion and use.

[0046] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved.
