A fender assembly 100 for a wheel 101 according to an embodiment of the utility model will now be described with reference to the accompanying drawings.

As shown in fig. 1-5, according to baffle assembly 100 for wheel 101 of an embodiment of the present invention, wheel 101 includes a hub 1011, a spoke 1012, and a rim 1013, spoke 1012 being connected between hub 1011 and rim 1013. The baffle plate assembly 100 is suitable for being installed on a wheel 101, and the baffle plate assembly 100 comprises a plurality of baffle plates 1, and the baffle plates 1 are suitable for being sequentially matched end to end along the circumferential direction of the wheel 101.

It should be explained here that the baffles 1 are sequentially engaged end to end in the circumferential direction of the wheel 101, that is, the tail part of each baffle 1 is engaged with the head part of the adjacent baffle 1 to form a closed loop, for example, in fig. 1 and 2, the baffles 1 are eight, the eight baffles 1 are sequentially arranged in the circumferential direction of the wheel 101, the eight baffles 1 are respectively a first baffle, a second baffle, a third baffle, a fourth baffle, a fifth baffle, a sixth baffle, a seventh baffle and an eighth baffle, the first baffle is engaged with the second baffle, and the second baffle is engaged with the third baffle … … and the eighth baffle is engaged with the first baffle.

As shown in fig. 4 and 5, each baffle plate 1 is movable between a shielding position in which each baffle plate 1 is in the shielding position and the baffle plate assembly 100 is adapted to completely shield the hub 1011 and the spokes 1012, and an open position in which each baffle plate 1 is in the open position and the baffle plate assembly 100 is adapted to expose at least a portion of the hub 1011, so that in the open position, the baffle plate assembly 100 may expose only a portion of the hub 1011, may expose not only a portion of the hub 1011 but also other portions of the wheel 101, such as exposing another portion of the hub 1011 to expose the entire hub 1011, or exposing the spokes 1012, or at least a portion of the rim 1013, etc., so that the baffle plate assembly 100 is switchable between the shielding position and the open position.

Specifically, as shown in fig. 1, the baffle assembly 100 is in a shielding state, and each baffle 1 is in a shielding position at this time, the hub 1011 and the spoke 1012 are completely shielded by the baffle assembly 100, so that when the wheel 101 is applied to a vehicle, a user cannot directly see the hub 1011 and the spoke 1012 from the appearance of the vehicle, and the wind resistance of the vehicle is effectively reduced; as shown in fig. 3, the baffle plate assembly 100 is in an open state, and each baffle plate 1 is in an open position, and a part of the hub 1011, for example, a mounting space corresponding to the mounting bolt 1016 on the hub 1011 is exposed, so that the wheel 101 can be conveniently assembled and disassembled without affecting the disassembly of the tire, and at the same time, because at least a part of the hub 1011 is exposed, the air flow can be increased, so that the effective heat dissipation of the wheel 101 is realized.

Therefore, the baffle plate assembly 100 is applied to the vehicle, and when the vehicle is at a high speed, the baffle plate assembly 100 can be switched to a shielding state, so that the wind resistance of the whole vehicle is reduced; when the vehicle is at a low vehicle speed, the barrier 1 of the barrier assembly 100 may be pushed away from the shielding position, for example, the barrier assembly 100 may be switched to the open state, so that the wheels 101 have different shapes; when the wheel 101 and brake temperatures are high, the damper assembly 100 may be switched to the open state to increase air flow for heat dissipation; when the wheel 101 has no heat dissipation requirement, the baffle plate assembly 100 can be switched to the shielding state to reduce the wind resistance.

According to the baffle plate assembly 100 for the wheel 101, the baffle plate assembly 100 can be switched between the shielding state and the opening state through the matching of the plurality of baffle plates 1, the wind resistance of the baffle plate assembly 100 is reduced in the shielding state, the heat dissipation of the wheel 101 is facilitated in the opening state of the baffle plate assembly 100, and the heat dissipation requirement of the wheel 101 is not influenced while the wind resistance is reduced.

It is understood that the exterior configuration of the baffle assembly 100 may be fabricated in various styling patterns to enrich the exterior styling of the vehicle.

Alternatively, when the barrier assembly 100 is switched from the shielding state to the opening state, the exposed portion of the wheel 101 of the barrier assembly 100 is gradually increased until the barrier assembly 100 is switched to the opening state, and the exposed portion of the wheel 101 of the barrier assembly 100 is the largest. At this time, as long as the shutter assembly 100 is switched to be away from the shielding state, for example, when the shutter assembly 100 is in a state between the shielding state and the open state, as shown in fig. 2, the heat dissipation of the wheel 101 can be also achieved.

Optionally, the baffle 1 is a metal piece, and the metal piece has the advantages of high structural strength, good heat conduction effect and the like; it will of course be appreciated that the material of the baffle 1 is not so limited.

According to a further embodiment of the present invention, as shown in fig. 4-9, each baffle plate 1 is adapted to be slidably engaged with the wheel 101 through the first sliding assembly 2, such that each baffle plate 1 is movable between a shielding position and an opening position, adjacent two baffle plates 1 are slidably engaged with each other through the second sliding assemblies 3, respectively, and in a shielding state, the extending direction of the second sliding assemblies 3 is parallel to the radial direction of the wheel 101. Particularly, baffle 1 moves between sheltering from the position and the open position through first subassembly 2 that slides, realize the state and the open mode of sheltering from of baffle subassembly 100, slide the cooperation through second subassembly 3 between two adjacent baffles 1, the frictional force has been reduced, it is too big to avoid direct fit frictional force between two baffles 1, the jam, the noise scheduling problem, simultaneously can avoid taking place to interfere when every baffle 1 moves relative wheel 101 with between the adjacent baffle 1, make baffle 1 move smoothly between sheltering from the position and the open position.

Moreover, when the barrier assembly 100 is switched between the shielding state and the opening state, each barrier 1 may only move relative to the wheel 101, so that the movement mode of the barrier 1 is simple, which is beneficial to simplifying the structure of the barrier assembly 100. For example, as shown in fig. 2, the barrier 1 moves 40mm from the shielding position with respect to the wheel 101, and as shown in fig. 3, the barrier 1 moves 60mm from the shielding position to the opening position with respect to the wheel 101.

It can be understood that when the baffle 1 is moved relative to the wheel 101 by the first sliding assembly 2, the extending direction of the second sliding assembly 3 can be changed. The "extending direction of the second sliding assembly 3" can be understood as the relative moving direction of two adjacent baffles 1.

According to a further embodiment of the present invention, the angle between the extending direction of the first sliding assembly 2 and the radial direction of the wheel rim 1013 is greater than 45 °, so that the moving direction of each baffle 1 relative to the wheel 101 is relatively biased to the circumferential direction of the wheel 101, so that when multiple baffles 1 slide simultaneously, the multiple baffles 1 move simultaneously to the open position and simultaneously move to the shielding position, and the baffle assembly 100 can be switched between the shielding state and the open state quickly. The "extending direction of the first sliding component 2" can be understood as the moving direction of the baffle plate 1 relative to the wheel 101.

Alternatively, as shown in fig. 13, the direction AA' in the figure is the extending direction of the first sliding module 2, and the angle between the extending direction of the first sliding module 2 and the radial direction of the rim 1013 is 67.5 °. The distance between the first sliding component 2 and the center of the wheel 101 can be specifically set according to actual requirements, and it can be understood that the distance between the first sliding component 2 and the center of the wheel 101 does not affect the switching of the baffle component 100 between the shielding state and the opening state.

According to some embodiments of the present invention, as shown in fig. 1, fig. 2, fig. 3, and fig. 8, eight baffle plates 1 are provided, each baffle plate 1 is formed into an isosceles triangle whose radial outer edge is an arc edge, that is, the baffle plate 1 is formed into a sector, the second sliding assembly 3 is disposed between the edges of two adjacent baffle plates 1, at this time, a vertex angle corresponding to each baffle plate 1 may be 45 °, and in a shielding state, the edge of each baffle plate 1 may extend in a radial direction of the hub 1013, so that on the premise of ensuring that eight baffle plates 1 can effectively shield the hub 1011 and the spoke 1012, material usage of the baffle plate 1 may be saved, and cost may be reduced. It is of course understood that the number of baffles 1 is not limited to 8 in the figure, for example, the number of baffles 1 may be 6.

Wherein, when the baffle plate assembly 100 is in the shielding state, the radially outer edge of the baffle plate 1 can be approximately flush with the radially inner edge of the rim 1013, that is, the radius of the structure formed by the plurality of baffle plates 1 can be substantially equal to the inner diameter of the rim 1013, so as to ensure that the baffle plate assembly 100 effectively and completely shields the hub 1011 and the spoke 1012; but is not limited thereto.

For example, in the example of fig. 8 and 9, the second sliding assembly 3 includes a second slide rail 31 and a second slider 32, the second slide rail 31 is formed on an edge of one of the two adjacent flappers 1, and the second slide rail 31 extends in an extending direction of the edge, the second slider 32 is formed on an edge of the other of the two adjacent flappers 1, and the second slider 32 extends in the extending direction of the edge.

According to some embodiments of the present invention, as shown in fig. 4-7, the first sliding assembly 2 includes a first slide rail 21 and a first sliding block 22, the first slide rail 21 extends along a straight line, the first slide rail 21 is adapted to be fixed on the rim 1013, the first sliding block 22 is fixed on the baffle plate 1, and the first sliding block 22 is in sliding fit with the first slide rail 21. Specifically, the first slide rail 21 and the first slide block 22 cooperate to enable the baffle 1 to move between the shielding position and the opening position relative to the wheel 101, and the first sliding assembly 2 is simple in structure and convenient to implement, and the number of the first slide rail 21 and the number of the first slide block 22 are the same as that of the baffle 1. It is understood, of course, that the form of the first sliding assembly 2 is not limited thereto.

For example, in the example of fig. 6, a plurality of baffle plates 1 may be disposed at one axial end of the wheel 101, and the first slider 22 may be disposed at a side of the baffle plate 1 facing the wheel 101, that is, the first slider 22 may be disposed at a back side of the baffle plate 1, so that the baffle plate 1 shields the first sliding assembly 2, and the appearance performance of the baffle plate assembly 100 is ensured.

According to some embodiments of the present invention, as shown in fig. 8 and 9, the second sliding assembly 3 includes a second slide rail 31 and a second slider 32, the second slide rail 31 is formed on one of the two adjacent baffle plates 1, the second slider 32 is formed on the other of the two adjacent baffle plates 1, and the second slider 32 is in sliding fit with the second slide rail 31. Particularly, the two adjacent baffles 1 are matched through the second sliding rail 31 and the second sliding block 32 to enable the two adjacent baffles 1 to slide relatively, the second sliding assembly 3 is simple in structure and convenient to realize, and the number of the second sliding rail 31 and the number of the second sliding block 32 are consistent with that of the baffles 1. It will of course be appreciated that the construction of the second glide assembly 3 is not so limited.

It should be noted that in the description of the present application, "and/or" is meant to include three parallel schemes, and taking "a and/or B" as an example, the scheme includes a scheme, or B scheme, or a scheme satisfied by both a and B. For example, in the structure of the first sliding assembly 2 and the second sliding assembly 3 in the present invention, the first sliding assembly 2 may be a first slide rail 21 matched with a first slide block 22, and the second sliding assembly 3 may be another structure; the first sliding component 2 can be in other structures, and the second sliding component 3 is a second sliding rail 31 matched with a second sliding block 32; or the first sliding component 2 may be a first slide rail 21 matched with the first slide block 22, and the second sliding component 3 may be a second slide rail 31 matched with the second slide block 32.

According to some embodiments of the present invention, as shown in fig. 3, the hub 1011 is provided with a mounting bolt 1016, the mounting bolt 1016 is used for mounting the hub 1011 to the vehicle body, and the shutter assembly 100 exposes the mounting bolt 1016 when the shutter assembly 100 is in the open state. Specifically, when the damper assembly 100 is in the open state, the mounting bolts 1016 are exposed, and at this time, the wheel 101 can be dismounted by dismounting the mounting bolts 1016, so that the mounting and dismounting of the wheel 101 is not affected by the arrangement of the damper assembly 100. It is understood that the baffle assembly 100 may shield the mounting bolts 1016 when the baffle assembly 100 is in the shielding state.

According to a further embodiment of the present invention, as shown in fig. 3, the number of the mounting bolts 1016 is plural, the plural mounting bolts 1016 are arranged at intervals along the circumferential direction of the hub 1011, the radius of the mounting space required for the plural mounting bolts 1016 is R, and the distance that the barrier 1 slides relative to the wheel 101 between the shielding position and the opening position is L, R, L satisfies:

where α is an angle between the moving direction of the barrier 1 between the shielding position and the opening position and the circumferential direction of the wheel 101. Therefore, the baffle plate assembly 100 can be effectively ensured to expose all the mounting bolts 1016 in the opening state, and meanwhile, the space area where the baffle plate assembly 100 is exposed can meet the requirement of dismounting and mounting space of the mounting bolts 1016.

For example, as shown in fig. 13, the AA 'direction is a moving direction of the barrier 1 between the shielding position and the opening position, the BB' direction is a circumferential direction of the wheel 101, and α is an angle between the AA 'direction and the BB' direction. Optionally, α is 22.5 °.

It will be appreciated that the value of R can be obtained by measurement, and that it is also easily possible to determine the sliding direction α of the first sliding assembly 2, i.e. to obtain the distance L by which the barrier 1 slides with respect to the wheel 101 between the blocking position and the open position.

According to a further embodiment of the present invention, as shown in fig. 10, the baffle plate assembly 100 further comprises: the driving device 4 comprises a driver 41, a rotating arm 42 and a pull rod 43, the driver 41 is suitable for being fixedly arranged on the hub 1011, the rotating arm 42 extends along the radial direction of the hub 1011, the rotating arm 42 is connected with the driver 41 to be driven by the driver 41 to rotate, one end of the length of the pull rod 43 is hinged with one end of the rotating arm 42, which is far away from the driver 41, and the other end of the length of the pull rod 43 is hinged with the baffle plate 1 to drive the baffle plate 1 to move. Specifically, the driver 41 drives the rotating arm 42 to rotate, the rotating arm 42 drives the pull rod 43, and the pull rod 43 drives the barrier 1 to move between the shielding position and the opening position, for example, the pull rod 43 can drive the barrier 1 to move in a straight line between the shielding position and the opening position.

Therefore, by arranging the driving device 4, the intelligent switching of the baffle assembly 100 between the shielding state and the opening state can be realized by controlling the driving device 4, the operation of the baffle assembly 100 is simplified, and the use convenience of the baffle assembly 100 is improved; moreover, the rotating arm 42 and the pull rod 43 which are connected in a hinged mode are arranged, so that the phenomenon that the pull rod 43 drives the baffle 1 to be blocked when the baffle 1 moves between the blocking position and the opening position is avoided, and smooth movement of the baffle 1 is achieved.

For example, in the example of fig. 10, 11 and 12, the driver 41 may be embedded in the center of the hub 1011, the driver 41 may be disposed coaxially with the hub 1011, the rotating arm 42 may extend in the radial direction of the wheel 101, the radially inner end of the rotating arm 42 may be connected to the driver 41, and the radially outer end of the rotating arm 42 is hinged to the pull rod 43.
