[0041] In order to make the objectives, technical solutions and advantages of the present application clearer, the following will be combined with the accompanying drawings for describing the present application in detail. Figures 1-5 The present application will be described in further detail with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments.

[0042] It should be understood that, although the terms first, second, third, etc. can be used in embodiments of the present application to describe, these descriptions should not be limited to these terms. These terms are only used to distinguish the descriptions. For example, in the absence of departing from the scope of the embodiments of the present application, the first can also be called the second, and similarly, the second can also be called the first.

[0043] A kind of openable and closeable rim covering structure for automobile, comprising:

[0044] The telescopic adjusting part 1 is fixed to the inner surface of the rear wheel cover, and the output end is connected with the covering mechanism 2, the telescopic adjusting part 1 is used for driving the covering mechanism 2 to move linearly and rotating the covering mechanism 2, the covering mechanism 2 is adjacent to the outer surface of the rear wheel 5, when the covering mechanism 2 is unfolded, the outer surface of the rear wheel 5 can be shielded.

[0045] The telescopic adjusting part 1 and the covering mechanism 2 are further connected with the driving part 3, the driving part 3 is arranged on the inner surface of the rear wheel cover and is drivingly connected with the telescopic adjusting part 1, the driving part 3 is used for driving the telescopic adjusting part 1 to rotate and synchronously driving the covering mechanism 2 to rotate, so that the covering mechanism 2 is unfolded or retracted.

[0046] When the covering mechanism 2 is unfolded, the telescopic adjusting part 1 can drive the covering mechanism 2 to move linearly, so that the outer surface of the unfolded covering mechanism 2 is in the same plane, thereby shielding the upper part of the outer surface of the rear wheel 5.

[0047] The telescopic adjusting part 1 comprises a plurality of telescopic adjusting devices 11 which are the same in structure, and each of the telescopic adjusting devices 11 is connected with the covering mechanism 2; the telescopic adjusting device 11 comprises an electromagnetic unit 110, a telescopic rod 111, a spring 112 and a limiting sheet 113; the electromagnetic unit 110 is fixed on the rear wheel cover and is connected with the telescopic rod 111, the electromagnetic unit 110 is used for driving the telescopic rod 111 to move linearly, the telescopic rod 111 is externally sleeved with the spring 112 and the limiting sheet 113 near the electromagnetic unit 110, the spring 112 is supported between the electromagnetic unit 110 and the limiting sheet 113, the limiting sheet 113 is in interference fit with the telescopic rod 111, the telescopic rod 111 is fixed with a pinion 4, the pinion 4 is connected with the driving part 3, and the free end of the telescopic rod 111 is fixedly connected with the covering mechanism 2.

[0048] It should be explained that the electromagnetic unit 110 controls the telescopic rod 111 to move linearly through the magnetic rod and the electromagnetic coil arranged inside, so as to drive the covering mechanism 2 to move linearly, and it should be explained that the linear movement of the telescopic rod 111 is controlled by the magnetic force inside the electromagnetic unit 110, so that the rotation of the telescopic rod 111 is not restricted in structure and has a certain degree of freedom.

[0049] The advantage of this design is that when the electromagnetic unit 110 is working, the telescopic rod 111 moves back under the suction of the electromagnetic unit 110, and the spring 112 is in a compressed state and is kept in the compressed state by the limiting piece 113. When the telescopic rod 111 extends, the limiting piece 113 moves outward under the action of the spring 112, drives the telescopic rod 111 to move synchronously, and limits the contact with the driving component 3 through the limiting piece 113, so that the outer surface of the covering mechanism 2 is exactly in the same plane, and the outer surface of the rear wheel 5 is covered. At the same time, due to the arrangement of the spring 112, when the telescopic rod 111 moves back and the spring 112 is compressed to the maximum deformation, the pinion 4 on the telescopic rod 111 and the driving component 3 cannot be completely separated, providing secondary protection, instead of relying on the electromagnetic unit 110 to control the telescopic rod 111 to move back to ensure that the pinion 4 on the telescopic rod 111 and the driving component 3 cannot be completely separated.

[0050] Further, the covering mechanism 2 comprises a plurality of sectors 21, each of which is connected with a telescopic rod 111, and a connection point is formed at the connection position. When the covering mechanism 2 is unfolded, the telescopic rod 111 can drive the sector 21 connected therewith to move linearly, so that the outer surfaces of the unfolded sectors 21 are flush, thereby wrapping the outer surface of the rear wheel 5.

[0051] In this embodiment, the covering mechanism 2 comprises eight sectors 21.

[0052] Further, the distance from the connection point formed at the connection position of each sector 21 and the tip of the sector 21 is the same, the eight connection points formed at the connection positions of the eight sectors 21 and the telescopic rods 111 are located on the same circumferential line, and the eight sectors 21 are uniformly arranged along the circumferential line. When the telescopic rod 111 and the sector 21 connected with the telescopic rod 111 rotate synchronously with the connection point as the center, the sector 21 can be unfolded or retracted.

[0053] Further, the driving component 3 comprises two driving units 31 which are the same in structure and are symmetrically distributed on the left and right sides of the inner surface of the rear wheel cover. The left driving unit 31 drives the telescopic rod 111 of the telescopic adjusting device 11 and the sector 21 connected with the telescopic rod 111 to rotate clockwise through the driving pinion 4, and the right driving unit 31 drives the telescopic rod 111 of the telescopic adjusting device 11 and the sector 21 connected with the telescopic rod 111 to rotate counterclockwise through the pinion 4, thereby unfolding or retracting the eight sectors 21.

[0054] Further, the number of the fan sectors 21 connected with the left driving unit 31 is the same as that of the fan sectors 21 connected with the right driving unit 31, both of which are four, and the fan sectors 21 on both sides are symmetrically arranged, further, the fan sectors 21 connected with the left driving unit 31 are arranged in staggered manner from inside to outside, and correspondingly, the fan sectors 21 connected with the right driving unit 31 are arranged in staggered manner from inside to outside.

[0055] Both of the driving units 31 comprise a driving motor 310 and a rack 311, the driving motor 310 is fixed on the rear wheel cover for driving the rack 311 to slide, the rack 311 is arranged on the inner surface of the rear wheel cover and engages with the pinion 4 on the telescopic rod 111, the output shaft of the driving motor 310 drives the rack 311 to slide through the transmission gear 312, and the rack 311 synchronously drives the pinion 4, the telescopic rod 111 of the telescopic adjusting device 11 and the fan sector 21 connected with the telescopic rod 111 to rotate, so as to expand or retract the fan sector 21.

[0056] Further, the outer surface of the rack 311 is provided with a limiting strip protruding along the length direction of the automobile, and correspondingly, the inner surface of the rear wheel cover is provided with a limiting groove matched with the limiting strip, the limiting groove is used for presetting the moving track of the rack 311.

[0057] It should be noted that the electromagnetic unit 110 of the telescopic adjusting device 1 and the driving motor 310 of the driving device 3 are respectively electrically connected with the central controller of the automobile, and the user can intelligently control the expansion and retraction of the covering mechanism 2 in the cab, which is simple to operate.

[0058] It should be further noted that a sunken platform is arranged at the lower edge of the rear wheel arch, and when the fan sector 21 is retracted, the fan sector 21 can be hidden in the sunken platform.

[0059] In use, the openable wheel cover structure for a vehicle is converted from the retracted state to the expanded state, at which time the drive motors 310 of the two drive units 31 drive the corresponding racks 311 to rotate by the same angle, that is, the drive motor 310 on the left side drives the corresponding rack 311 to rotate clockwise, and synchronously drives the sector 21 connected with the left rack 311 to rotate, and the drive motor 310 on the right side drives the corresponding rack 311 to rotate counterclockwise, and synchronously drives the sector 21 connected with the right rack 311 to rotate, when the sector 21 rotates to the specified position, at which time the electromagnetic unit 110 is turned off, the telescopic rod 111 pushes the sector 21 to the same plane under the action of the spring 112 and the limiting sheet 113, so as to eliminate the gap between the sectors 21, thereby reducing the wind resistance of the vehicle and improving the economy of the vehicle, when the cover structure 2 is converted from the expanded state to the retracted state, the telescopic rod 111 moves back under the action of the electromagnetic unit 110, thereby compressing the spring 112, so that the sectors 21 are sequentially misaligned and are on different planes, at which time the drive motors 310 of the two drive units 31 drive the corresponding racks 311 to rotate by the same angle, that is, the drive motor 310 on the left side drives the corresponding rack 311 to rotate counterclockwise, and synchronously drives the sector 21 connected with the left rack 311 to rotate, and the drive motor 310 on the right side drives the corresponding rack 311 to rotate clockwise, and synchronously drives the sector 21 connected with the right rack 311 to rotate, and stops when the sector 21 rotates to the specified position.
