Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a front bracket of a corrosion-resistant auxiliary frame. Background Art

[0002] The automobile subframe carries most of the weight of the car. The front subframe is an important safety and load-bearing component in the automobile chassis system. Its strength, rigidity, fatigue, etc. have extremely high requirements. It bears the steering, braking and vertical loads during the car's driving. The strength, rigidity, fatigue, etc. of the front subframe directly affect the safety and ride comfort of the entire vehicle.

[0003] After searching, in the prior art, Chinese Patent Publication (Announcement) No.: CN210912613U discloses a front subframe and a car with energy absorption function. In this utility model, when the vehicle collides, the concave design of the left and right longitudinal beams can make them have greater elastic deformation, which can unload part of the impact force, thereby enhancing their compressive resistance. In addition, both the left and right longitudinal beams adopt a three-section design. When the impact force borne by the left front curved end reaches the limit, the left vertical end will deform. This process enhances the deformation capacity of the left longitudinal beam and effectively improves the energy absorption capacity of the left longitudinal beam during the collision.

[0004] However, the device still has the following defects: the applicant believes that although the above-mentioned front subframe can reduce the energy generated by the collision when the vehicle collides, the front subframe is an integral structure and the replacement cost is high. At the same time, the traditional front subframe has poor corrosion resistance.

[0005] Therefore, those skilled in the art provide a corrosion-resistant front bracket of a sub-frame to solve the problems mentioned in the above-mentioned prior art. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The embodiment of the present application discloses a corrosion-resistant front bracket of a sub-frame, including a frame body 1, a front bracket body 2 is provided on both sides of the back of the frame body 1, a splitting mechanism is provided between the front bracket body 2 and the frame body 1, the splitting mechanism includes a docking block 3 fixedly assembled on the front of the front bracket body 2, a docking groove 4 used for matching with the docking block 3 is provided on the back of the frame body 1, a first mounting hole 5 is provided on the front and back of the top of the docking block 3, and a second mounting hole 6 corresponding to the position of the first mounting hole 5 is provided on the top and bottom of the frame body 1. The inner cavities of the mounting holes 6 are all threadedly connected with mounting parts 7, and a reinforcement mechanism is provided between the front bracket body 2. The frame body 1 and the front bracket body 2 are both made of aluminum alloy. The surfaces of the frame body 1 and the front bracket body 2 are sequentially provided with a corrosion-resistant structure consisting of an inner layer 8, a middle layer 9 and an outer layer 10 from the inside to the outside. The inner layer 8 is a galvanized layer, which is galvanized by an electroplating method. The middle layer 9 is an anodized layer, and a dense oxide film is formed on the surface of the inner layer 8 by electrolysis. The outer layer 10 is a coating layer, and the epoxy resin paint is evenly applied to the surface of the middle layer 9 using a spray gun.

[0025] As a technical optimization solution of the present invention, by removing the mounting member 7 from the inner cavity of the first mounting hole 5 and the second mounting hole 6, and removing the docking block 3 from the docking groove 4, the front bracket body 2 can be disassembled and replaced separately, and vice versa, the front bracket body 2 can be quickly installed, thereby significantly reducing the replacement cost of the vehicle in the event of a collision, making maintenance more convenient and economical;

[0026] By immersing the frame 1 and the front bracket body 2 in a galvanizing solution, performing galvanizing treatment by electroplating, and then immersing the plated surface in an anodizing solution, a dense oxide film is formed on the surface by electrolysis, and finally using a spray gun to evenly apply epoxy resin paint on the surface of the anodized layer, and then performing a fixation treatment, the corrosion resistance of the frame 1 and the front bracket body 2 in harsh environments can be effectively improved.

[0027] The reinforcing mechanism includes a card slot 11 fixedly assembled on the inner side of the front bracket body 2, and a cross bar 12 is clamped on the inner side of the card slot 11. A first fixing slot 13 is provided on both sides of the top of the cross bar 12, and a second fixing slot 14 corresponding to the position of the first fixing slot 13 is provided on the top and bottom of the card slot 11. The inner cavities of the first fixing slot 13 and the second fixing slot 14 are both threadedly connected with a fixing piece 15.

[0028] As a technical optimization solution of the present invention, the design of the cross bar 12 can improve the strength of the front bracket body 2, thereby improving the overall safety, and the card slot 11 can facilitate the connection between the cross bar 12 and the front bracket body 2, and then the fixing member 15 can be installed and disassembled with the first fixing groove 13 and the second fixing groove 14 through a threaded connection. In the event of a collision, if the cross bar 12 is not damaged, it can be disassembled and reused, further reducing maintenance costs.

[0029] The sizes of the docking block 3 and the docking slot 4 match, and the docking block 3 is snap-fitted into the inner cavity of the docking slot 4 .

[0030] As a technical optimization solution of the present invention, by docking the docking block 3 and the docking groove 4, the first mounting hole 5 and the second mounting hole 6 can be easily aligned, thereby facilitating the fixation of the mounting member 7.

[0031] Working principle: When a collision occurs, the front bracket body 2 is impacted first. If it is damaged and needs to be replaced, the front bracket body 2 can be disassembled by moving the mounting member 7 away from the inner cavity of the first mounting hole 5 and the second mounting hole 6, thereby achieving a separate replacement of the front bracket body 2. If the cross bar 12 used to increase the strength of the front bracket body 2 does not need to be replaced, the user can disassemble and reuse the cross bar 12 through the cooperation of the first fixing groove 13, the second fixing groove 14 and the fixing member 15, thereby reducing maintenance costs. At the same time, the frame 1 and the front bracket body 2 are made of aluminum alloy, and multi-level protection is provided through the cooperation of the inner layer 8, the middle layer 9 and the outer layer 10, which can significantly improve the corrosion resistance and surface quality of the subframe front bracket.

[0032] In the present invention, unless otherwise clearly stipulated and limited, the terms "install", "set", "connect", "fix", "screw" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the present invention according to the specific circumstances.

[0033] In summary, the above is only a preferred embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. All equivalent changes and modifications based on the shape, structure, characteristics and spirit described in the claims of the present invention should be included in the scope of the claims of the present invention.
