Description

Technical Field

[0001] The utility model relates to the technical field of fender brackets, in particular to a lightweight fender bracket. Background Art

[0002] Heavy truck fenders are installed above the wheels to prevent mud from being brought onto the vehicle body by the wheels, and to prevent mud, sand and stones from being thrown onto the vehicle body on rainy days and scratching the paint. The fenders are fixed to the vehicle beams through fender brackets. Currently, existing automobile fender brackets are usually made of steel, which has fatigue damage and a short service life. Some fender brackets are made of aluminum alloy, which is slightly stronger than steel fenders and has a slightly longer service life.

[0003] However, the main reasons why the existing fender bracket has poor fatigue performance of metal materials are:

[0004] Due to the limited layout space, the fender mounting pipe beam needs to extend a long cantilever beam to install the fender, which easily causes the fender to shake during the movement of the vehicle body. Usually, the fender mounting pipe beam is a straight structure, and the pipe beam and the mounting seat are rigidly connected. The vibration generated during the driving of the car can easily cause fatigue durability and resonance failure of the rigid connection of the bracket. The fender bracket is prone to fatigue fracture and has a short service life. Utility Model Content

[0005] The utility model aims to provide a lightweight fender bracket to solve the technical problems in the prior art of fatigue durability and resonance failure of the fender bracket due to vibration during the driving of the car.

[0006] In order to solve the above technical problems, the utility model specifically provides the following technical solutions:

[0007] A lightweight fender bracket comprises a tube beam, one end of which is connected to a fender support, and the tube beam is perpendicular to the fender support, at least two groups of reinforcing ribs are arranged on the beam body of the tube beam close to the fender support, at least two groups of the reinforcing ribs are evenly distributed on the circumferential surface of the tube beam, at least one portion of the reinforcing ribs is connected to the fender support, and bolt holes are arranged at the four corners of the fender support.

[0008] As a preferred solution of the utility model, the fender support is provided with a mounting hole for mounting the tube beam, the end of the tube beam passing through the fender support is provided with a hollow plastic plate, and the fender support is provided with a mounting groove matching the hollow plastic plate.

[0009] As a preferred solution of the utility model, at least two groups of the reinforcing ribs are centrally symmetrically distributed on the circumferential surface of the tube beam relative to the axis of the tube beam, and the thickness of at least one group of the reinforcing ribs is greater than the thickness of the reinforcing ribs of other groups.

[0010] As a preferred solution of the utility model, the connection end between the tube beam and the fender support deviates from the geometric center of the fender support.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model arranges multiple groups of reinforcing ribs at the connection between the tube beam and the fender support to support the tube beam, while reducing the impact of vibration caused by the action of a force couple on the tube beam and improving the stability of the connection between the tube beam and the fender support.

[0013] In order to more clearly illustrate the implementation of the utility model or the technical solution in the prior art, the following is a brief introduction to the drawings required for the implementation or the prior art description. Obviously, the drawings in the following description are only exemplary, and for ordinary technicians in this field, other implementation drawings can be derived from the provided drawings without creative work.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1 As shown, the utility model provides a lightweight fender bracket.

[0020] It includes a tube beam 1, one end of which is connected to a fender support 2, and the tube beam 1 is perpendicular to the fender bracket 3, at least two groups of reinforcing ribs 4 are arranged on the beam body of the tube beam 1 close to the fender support 2, at least two groups of reinforcing ribs 4 are evenly distributed on the circumferential surface of the tube beam 1, at least one part of the reinforcing ribs 4 is connected to the fender support 2, and bolt holes 5 are arranged at the four corners of the fender support 2.

[0021] Since the pipe beam 1 needs to be installed with a fender, the installation of the fender is limited by the space of the wheel part of the car and cannot be directly installed on the car. A very long pipe beam needs to be extended for installation. Then, the force couple received by the pipe beam 1 during the operation of the car easily causes fatigue damage to the pipe beam 1, especially the connection between the pipe beam 1 and the fender support 2. To this end, the utility model sets multiple groups of reinforcing ribs at the connection between the pipe beam 1 and the fender support 2 to support the pipe beam 1, and at the same time can reduce the influence of vibration caused by the force couple on the pipe beam 1, and improve the stability of the connection between the pipe beam 1 and the fender support 2.

[0022] Furthermore, if the fender bracket 2 is directly rigidly connected to the tube beam 1, the vibration of the tube beam 1 will still cause fatigue damage to the tube beam 1 and the connection between the tube beam 1 and the fender bracket 2. It is just that in the above structure, the service life of the connection between the two can be extended as much as possible. In order to optimize the connection between the fender bracket 2 and the truck structure, the fender bracket 2 of the utility model is provided with a mounting hole 6 for mounting the tube beam 1, and the end of the tube beam 1 passing through the fender bracket 2 is provided with a hollow plastic plate 7, and the fender bracket 3 is provided with a mounting groove 3 for matching the hollow plastic plate 7, wherein the hollow plastic plate 7 is made of PET material and has a hollow structure, and its purpose is to provide a shock-absorbing connection between the fender bracket 2 and the automobile structure.

[0023] like Figure 2 As shown, the range of the installation groove 3 of the hollow plastic plate 7 does not include the bolt hole 5, so that the bolt installed in the bolt hole 5 is still fastened to the automobile structure by bolts, and the force couple between the tube beam 1 and the fender support 2 will act on the hollow plastic plate 7, and the hollow plastic plate 7 plays the role of a shock-absorbing pad, thereby effectively reducing the fatigue damage effect between the tube beam 1 and the fender support 2.

[0024] The pipe beam 1 of the utility model is not designed at the center of the fender support. The connection end of the pipe beam 1 and the fender support 2 deviates from the geometric center of the fender support 2 and is arranged at a place where the moment is reduced and fatigue fracture is most likely.

[0025] Correspondingly, in the fatigue-prone area, at least two groups of reinforcing ribs 4 are centrally symmetrically distributed on the circumferential surface of the tube beam 1 relative to the axis of the tube beam 1, and the thickness of at least one group of reinforcing ribs 4 is greater than the thickness of the other groups of reinforcing ribs 4.

[0026] It is further explained that in order to improve the lightweight effect and performance of the fender support 2, the utility model adopts a composite material reinforced with continuous glass fibers.

[0027] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
