Description

Technical Field:

[0001] The utility model relates to an anti - falling wheel protective cover, which belongs to the technical field of automobiles. Background Art:

[0002] As an important part of an automobile, the wheel assembly mainly plays the role of bearing the weight of the whole vehicle and transmitting the driving force. In the field of commercial vehicles, wheels generally have aluminum alloy rims or steel rims. Steel wheels have lower costs compared to aluminum alloy wheels and are widely used in truck models. However, when steel wheels are used, a protective cover is generally installed on the side of the wheel. The protective cover is usually a plastic part, which plays a role in decorating the whole vehicle, reducing the wind resistance of the wheel, and helping the wheel dissipate heat.

[0003] Due to the relatively complex operating conditions of trucks and the relatively common phenomenon of overloading of trucks, when the vehicle is in use, when the wheel is deformed due to overloading or being subjected to a large impact, due to the defects in the fixing structure between the wheel protective cover and the wheel, it is easy to cause the protective cover to fall off during vehicle driving, resulting in safety and after - sales quality problems.

[0004] Therefore, it is necessary to improve the existing technology to solve the deficiencies of the existing technology. Content of the Utility Model:

[0005] The utility model provides an anti - falling wheel protective cover to solve the problems existing in the above - mentioned existing technology, which can effectively avoid the situation of the wheel protective cover falling off.

[0006] The utility model adopts the following technical scheme: An anti - falling wheel protective cover is installed on a steel rim. It includes a wheel cover body and a wheel cover snap ring installed on the wheel cover body. The wheel cover body includes a plurality of outer - ring fixed feet formed on the inner surface of its outer circumference and spaced apart. Grooves are formed on the steel rim at positions corresponding to the outer - ring fixed feet. The wheel cover snap ring is installed on the inner side wall of the outer - ring fixed feet. A plurality of spaced - apart middle - part sinking platforms are formed on the inner surface of the wheel cover body and inside the outer - ring fixed feet. Through - holes are formed on the steel rim at positions corresponding to the middle - part sinking platforms. Bolts are passed through the through - holes and the middle - part sinking platforms, and wheel nuts are screwed on the bolts. A plurality of spaced - apart inner - ring fixed feet and inner - ring positioning feet are formed on the inner surface of the wheel cover body and inside the middle - part sinking platforms. Grooves are respectively formed on the steel rim at positions corresponding to the inner - ring fixed feet and the inner - ring positioning feet.

[0007] Furthermore, outer - ring positioning feet are formed on both sides of each outer - ring fixed foot on the inner surface of the wheel cover body. A notch for supporting the wheel cover snap ring is formed at the end of the outer - ring positioning foot.

[0008] Furthermore, the outer wall of the outer ring fixing clip and the groove are in interference fit, and the interference amount is 0.1 - 0.2 mm.

[0009] Furthermore, the wheel cover retaining ring is made of 65Mn high-elastic material.

[0010] Furthermore, the material of the wheel cover body is PC + ABS or PA6.

[0011] Furthermore, the wheel nut and the steel rim are in tapered surface fit.

[0012] The utility model has the following beneficial effects: By designing a plurality of limiting and fixing structures on the wheel cover, the axial reliable fixing and radial installation and positioning fixing of the wheel protection cover are realized, and the problem of falling off caused by various factors is avoided.

[0021] The following further describes the present utility model with reference to the drawings.

[0022] The anti-dropping wheel protection cover 2 of the present utility model is installed on the steel rim 1, and it includes a wheel cover body 2-2 and a wheel cover retaining ring 2-1 installed on the wheel cover body 2-2. The wheel cover retaining ring 2-1 can be made of 65Mn high-elastic material, and the wheel cover body 2-2 can be made of plastic parts, and the common materials include PC + ABS, PA6, etc.

[0023] The wheel cover body 2-2 includes a plurality of outer ring fixing clips 2-21 formed on the inner surface at the outer circumference thereof and spaced apart. Grooves are formed at positions on the steel rim 1 corresponding to the outer ring fixing clips 2-21. The outer side wall of the outer ring fixing clip 2-21 and the groove are in interference fit, and the interference amount is 0.1-0.2 mm. A wheel cover retaining spring 2-1 is installed on the inner side wall of the outer ring fixing clip 2-21. Outer ring positioning clips 2-22 are formed on both sides of each outer ring fixing clip 2-21 on the inner surface of the wheel cover body 2-2. A notch 2-22-1 for supporting the wheel cover retaining spring 2-1 is formed at the end of the outer ring positioning clip 2-22. After the wheel cover body 2-2 is assembled, when the wheel cover body 2-2 is pulled outwards, the outer ring fixing clip 2-21 needs to deform inwards. The groove of the steel rim 1 and the wheel cover retaining spring 2-2 act together in two directions to provide a large pulling-off force to prevent the wheel guard 2 from falling off. At the same time, the outer ring positioning clip 2-22 provides axial positioning and limiting functions.

[0024] A plurality of spaced-apart middle sunk platforms 2-23 are formed on the inner surface of the wheel cover body 2-2 at positions inside the outer ring fixing clips 2-21. Through holes (not shown) are formed at positions on the steel rim 1 corresponding to the middle sunk platforms 2-23. After bolts pass through the through holes and the middle sunk platforms 2-23, wheel nuts 3 are tightened.

[0025] The wheel nut 3 and the steel rim 1 are in tapered surface fit. The middle sunk platform 2-23 is designed on the wheel cover body 2-2. After the wheel guard 2 is assembled, the middle sunk platform 2-23 is clamped between the steel rim 1 and the wheel nut 3. When the wheel guard 2 is pulled outwards, the wheel nut 3 provides resistance to prevent pulling-off at this place. At the same time, the middle sunk platform 2-23 can play a role in circumferential positioning, realizing the axial pressing and anti-rotation functions of the wheel guard 2.

[0026] A plurality of spaced-apart inner ring fixing clips 2-24 and inner ring positioning clips 2-25 are formed on the inner surface of the wheel cover body 2-2 at positions inside the middle sunk platforms 2-23. Slots (not shown) are respectively formed at positions on the steel rim 1 corresponding to the inner ring fixing clips 2-24 and the inner ring positioning clips 2-25. The axial positioning of the wheel guard 2 is realized through the cooperation of the inner ring positioning clip 2-25 and the slot. When the wheel guard 2 is pulled outwards, the axial fixation of the wheel guard 2 is realized through the cooperation of the inner ring fixing clip 2-24 and the slot.

[0027] For the anti-detachment wheel protective cover of the present utility model, during assembly, place the wheel protective cover 2 on the rim of the steel rim 1. Align the sunken platform 2-23 in the middle of the wheel cover body 2-2 with the through hole on the steel rim 1, and tighten the 6 wheel nuts 3 one by one. Apply a certain force in the direction towards the steel rim 1 to the outer fixing feet 2-21 and the inner fixing feet 2-24, so that the outer fixing feet 2-21 and the inner fixing feet 2-24 are successively clamped into the corresponding grooves and card slots of the steel rim 1 to complete the assembly of the wheel protective cover 1.

[0028] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be regarded as the protection scope of the present utility model.
