Detailed Description

The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

In the present disclosure, the use of directional terms such as "inner and outer" is intended to refer to the proper profile of the corresponding component without the contrary intention. Furthermore, the terms "first," "second," and the like, as used in this disclosure, are intended to distinguish one element from another, and not necessarily for order or importance.

As shown in fig. 1, the present disclosure provides a wheel guard fixing bracket, including a base 1 for connecting with a vehicle frame and a tubular beam 2 fixed on the base 1 for mounting a wheel guard, wherein the tubular beam 2 includes a first branch section 21 and a second branch section 22 adjacent to each other, a friction coefficient of the first branch section 21 is greater than a friction coefficient of the second branch section 22, and the first branch section 21 is formed at least at a portion of the tubular beam 2 for being sleeved by the wheel guard. Through the technical scheme, the wheel shield can be sleeved on the tubular beam 2 in an interference fit manner, so that the wheel shield and the first support section 21 generate large friction force and can be prevented from generating movement along the axial direction of the tubular beam 2. Like this, the wheel guard shield can not frequent wearing and tearing to can improve life, and the wheel guard shield remains the position of settlement throughout, can protect automobile body and chassis effectively, promotes the stability of whole car.

It should be noted that in the present disclosure, the first branch section 21 and the second branch section 22 of the tubular beam 2 have the same diameter and can be sleeved by the wheel guard in an interference fit manner, wherein the friction force between the first branch section 21 and the wheel guard is greater than the friction force between the second branch section 22 and the wheel guard.

Specifically, the wheel guard cover includes the installation cover, and the installation of wheel guard cover is realized through the cooperation of cup jointing of installation cover and tubular beams 2. The first branch section 21 is formed at least on the portion of the tubular beam 2 for being sleeved by the wheel guard, that is, the first branch section 21 at least partially coincides with the mounting sleeve. For example, according to an example, the first branch section 21 has the same length as the mounting sleeve, in this case, the two sections may be completely overlapped or staggered, and when the two sections are completely overlapped, the first branch section 21 may also play a positioning role in mounting the wheel guard; according to another example, the length of the first branch section 21 may be smaller than the length of the mounting sleeve, in which case the first branch section 21 may be completely covered by the mounting sleeve or may be staggered from the mounting sleeve; according to another example, the length of the first branch section 21 may be greater than the length of the mounting sleeve, in which case the first branch section 21 may completely cover the mounting sleeve or may be offset from the mounting sleeve.

The present disclosure is not limited to the method for forming the difference between the friction coefficients of the first branch section 21 and the second branch section 22, for example, according to an embodiment, referring to fig. 1, the outer circumference of the first branch section 21 may be formed with a knurled knurl to increase the friction coefficient. In this case, when the tubular beam 2 is machined, the optical axis may be first formed, and the first leg 21 may be formed by embossing a portion of the axial section, and the second leg 22 may be formed by an axial section that is not embossed. The manner in which the present disclosure increases the coefficient of friction of the first branch section 21 is not limited to the formation of cross-hatched knurls, and other methods may be used, for example, the first branch section 21 may also be provided as a frosted outer surface.

According to some embodiments, the number of the first branch sections 21 and the second branch sections 22 may be plural respectively and arranged alternately. That is, the first branch sections 21 are formed at a plurality of positions of the tubular beam 2, ensuring that the wheel guard does not axially shift. And, compare in the form that whole tubular beams 2 all designed for this kind of big coefficient of friction of first subsection 21, this kind of segmentation design can reduce manufacturing cost, and whole tubular beams 2 all designs big coefficient of friction and can lead to the difficult installation of wheel guard shield. The number of the first branch sections 21 is not particularly limited in the present disclosure, and may be set according to actual needs.

According to some embodiments, the wheel guard may include two of the above-described mounting sleeves, in which case, as shown in fig. 1, the first branch sections 21 may be two in number and disposed corresponding to the positions of the two mounting sleeves, respectively.

According to some embodiments, the base 1 and the tubular beam 2 may be connected by welding, for example, in the form of friction welding. The strength of the welding part can be higher than that of the tubular beam 2, and the mode of using vulcanized rubber in the related technology is replaced through a welding mode, so that the problems of structure aging and the like can be avoided, and the service life and the stability of the structure are improved.

Further, referring to fig. 1 and 2, one end of the base 1 close to the tubular beam 2 may be formed with a connection column 12 for welding with the tubular beam 2, wherein the connection column 12 may be configured as a hollow sleeve, and the tubular beam 2 is inserted into the hollow sleeve in a shape-fitting manner, i.e. the tubular beam 2 and the hollow sleeve may first be in a sleeved relationship and then welded, so that the connection between the tubular beam 2 and the base 1 is firmer. According to another embodiment, one end of the tubular beam 2 close to the base 1 can also be provided as a hollow structure, and the base 1 is inserted into the tubular beam 2 in a form-fitting manner.

Further, as shown in fig. 1 to 3, one end of the base 1 near the vehicle frame may be formed with a support pillar 11 for abutting against the vehicle frame, and the base 1 is mounted to the vehicle frame by a fastener passing through the support pillar 11. This fastener can be parts such as bolt, screw, and under this kind of connected mode, base 1 can have torsional deformation's trend when the motion of following the frame shakes to absorb partial energy, reduce stress concentration, and then can avoid the emergence of wheel guard fixed bolster fracture phenomenon.

Further, the number of the supporting columns 11 may be three, and the three supporting columns 11 enclose a triangular structure, that is, on the premise of ensuring sufficient stability of the connection, the base 1 has a greater tendency of torsional deformation.

According to one embodiment, the support columns 11 may be configured as cylinders, which facilitates the spreading of the forces acting on the support columns 11 and avoids stress concentrations.

The present disclosure also provides a vehicle including the wheel guard fixing bracket described above. The vehicle provided by the present disclosure has all the advantages of the wheel guard fixing bracket, and the description is omitted here.

The preferred embodiments of the present disclosure are described in detail with reference to the accompanying drawings, however, the present disclosure is not limited to the specific details of the above embodiments, and various simple modifications may be made to the technical solution of the present disclosure within the technical idea of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.

It should be noted that, in the foregoing embodiments, various features described in the above embodiments may be combined in any suitable manner, and in order to avoid unnecessary repetition, various combinations that are possible in the present disclosure are not described again.
