Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1, the spare wheel cover structure of the automobile comprises a rear door panel 1, the spare wheel cover structure comprises a cylindrical housing 2, one end of the housing 2 is open, the other end of the housing is closed, the spare wheel cover structure further comprises a positioning sleeve 3 with one end fixed on the outer side wall of the rear door panel 1 in an annular shape and a screw rod 4 with one end fixed on the outer side wall of the rear door panel 1 and arranged coaxially with the positioning sleeve 3, a connecting sleeve 5 in threaded connection with the screw rod 4 is arranged on the inner bottom surface of the housing 2, a flange 21 is arranged at the outer end of the housing 2, a gap 6 is arranged between the outer end surface of the housing 2 and the outer side wall of the rear door panel 1, the positioning sleeve 3 extends into the housing 2, an annular boss 31 is arranged on the outer peripheral surface of the positioning sleeve 3, and a drain hole 22. The design size of the positioning sleeve 3 is matched with the size of a corresponding spare tire, after the spare tire is placed in the positioning sleeve 3, the housing 2 is connected with the screw rod 4 in a screwing mode through the connecting sleeve 5, so that the housing 2 is fixed on the screw rod 4, the positioning sleeve 3 is wrapped by the housing 2, and a gap 6 between the outer end face of the housing 2 and the outer side wall of the rear door panel 1 ensures that the inside of the housing 2 and the inside of the positioning sleeve 3 can be ventilated with the outside; when raining, rainwater can flow to the outer peripheral face of the positioning sleeve 3 along the outer side wall of the rear door panel 1 through the gap 6, but due to the existence of the boss 31, the boss 31 forms a water baffle plate to prevent the rainwater from entering the positioning sleeve 3, the rainwater can drip on the inner peripheral face of the bottom end of the housing 2 along the outer peripheral face of the positioning sleeve 3, and the rainwater is discharged outwards through the gap 6 and the drainage hole 22. This spare wheel cover structure's simple structure, the installation and the easy dismounting of housing 2 to can have the effect of keeping off the rain and ventilating simultaneously.

As shown in fig. 1, a through hole 23 is opened on the outer peripheral surface of the outer end of the housing 2, a threaded hole 31a corresponding to the through hole 23 is opened on the outer peripheral surface of the boss 31, a fastening member 7 is provided in the through hole 23, and one end of the fastening member 7 is in threaded connection with the threaded hole 31 a. This structure carries out circumference location to housing 2 through fastener 7, avoids the vehicle to lead to housing 2 to take place to become flexible because of jolting at the in-process of traveling, improves housing 2's location effect.

As shown in fig. 1, a rubber pad 8 is fixed on a portion of the outer side wall of the rear door panel 1 located inside the positioning sleeve 3. This structure is kept apart back door plant 1 and spare tyre through rubber pad 8, avoids spare tyre and door plant 1 direct contact fish tail back door plant 1 to can also reduce the noise that the spare tyre drunkenness sent when the vehicle traveles.

As shown in fig. 1, an inner annular sleeve 9 and an outer annular sleeve 10 are fixed on the inner bottom surface of the housing 2, the inner annular sleeve 9 and the outer annular sleeve 10 are coaxially arranged, and the outer end of the positioning sleeve 3 extends between the inner annular sleeve 9 and the outer annular sleeve 10. The structure enables the outer end part of the positioning sleeve 3, the inner ring sleeve 9 and the outer ring sleeve 10 to form labyrinth seal, external dust is not easy to enter the positioning sleeve 3, and the dustproof effect is improved.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
