Description

Technical Field

[0001] The utility model relates to the technical field of vehicle frames, in particular to a high-load-bearing and fatigue-resistant vehicle frame assembly. Background Art

[0002] The frame assembly is a frame structure that spans the front and rear axles of the car, commonly known as the beam. It is the base of the car. It is generally composed of two longitudinal beams and several cross beams, and is supported on the wheels via the suspension device, front axle and rear axle. It connects the body, engine, suspension and other components, and bears their weight and the impact from the road. The frame assembly not only supports and connects the various assemblies of the car, but also ensures that they remain in a relatively correct position. It is vital to the overall structural strength and stability of the car. If there is a slope or bulge in front of the vehicle, the bottom of the vehicle will likely collide directly with these inclined obstacles, causing scratches. Therefore, protection is needed to prevent scratches from occurring to avoid damage to the vehicle.

[0003] The utility model with the authorization publication number CN217198353U provides a frame assembly, which belongs to the technical field of "frame", and the protected claim: "including a first main frame cross beam, both sides of the first main frame cross beam are fixedly connected to a main frame longitudinal beam, and one side of the two main frame longitudinal beams is provided with a plurality of first fixing holes, and the plurality of first fixing holes are linearly and evenly distributed, one side of the first main frame cross beam is fixedly connected to two supporting longitudinal beams, and one side of the two supporting longitudinal beams is fixedly connected to a second main frame cross beam. The advantage of the utility model is that the first fixing hole in the first main frame cross beam in the frame assembly is used to fix multiple components such as the first support beam, the second support beam and the tail support plate, so that such components are very easy and convenient to install, and the stabilization effect can be achieved by installing the components in the corresponding fixed air, and the bottom of each section of the supporting structure has a supporting longitudinal beam of the supporting cross beam for reinforcement."

[0004] Although this equipment has the advantages of high stability and easy installation, when the vehicle is running with high load, the frame is pressed down and the bottom of the frame is easily scratched. If no measures are taken to deal with it, the frame will be damaged or its performance will be affected. For this reason, we propose a high-load and fatigue-resistant frame assembly.

DETAILED DESCRIPTION

[0022] 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.

[0023] Embodiment 1

[0024] like Figure 1-4 As shown, in this embodiment, a high-load-bearing and fatigue-resistant frame assembly includes a crossbeam 1 and a protection component 2, and the protection component 2 is arranged at the bottom of the crossbeam 1;

[0025] The protection component 2 includes a rotating block 201 and a rotating rod 206; the rotating block 201 is fixedly connected to the bottom of the beam 1, the bottom end of the rotating block 201 is rotatably connected to a rotating plate 202, the upper end surface of the rotating plate 202 is fixedly connected to a first rotating shaft 203, the first rotating shaft 203 is rotatably connected to a suspension 204 outside, the top of the suspension 204 is rotatably connected to a second rotating shaft 205, and the top of the second rotating shaft 205 is fixedly connected to the bottom surface of the beam 1; the rotating rod 206 is rotatably connected to one side of the rotating plate 202, and the external fixed sleeve of the rotating rod 206 is provided with a rubber sleeve 207.

[0026] During specific implementation, the two parts of the power assembly are respectively installed on the front plate 401 and the rear plate 402, and then the frame assembly and other components are installed. When the vehicle is driving and is scratched, it will first touch the rubber sleeve 207, and then immediately drive the rotating rod 206 to rotate. Through the rotation, a part of the scratching force is deflected. When the rotating rod 206 rotates, it will drive the rotating plate 202 to rotate upward through the cooperation of the rotating block 201, and drive the multiple suspensions 204 to contract and buffer with the cooperation of the first rotating shaft 203 and the second rotating shaft 205. In this way, by deflecting and buffering the force generated by the scratch, it is possible to avoid damage to the frame or affecting its performance.

[0027] In addition, it should be noted that the suspension 204 is a prior art and is provided with a damping mechanism, and the prior art will not be described in detail.

[0028] like Figure 3 As shown, the bottom surfaces of the two rotating plates 202 are arc-shaped, and the bottoms of the two rotating plates 202 are tilted downward. The downward tilted setting allows them to directly contact the scratched object and perform corresponding deflection and offset. The bottom surfaces of the rotating plates 202 are arc-shaped, and the arc shape can form a transition, which is convenient for deflecting scratches.

[0029] Furthermore, the three rubber sleeves 207 are all made of high-density rubber material, which has excellent durability and wear resistance. It can withstand repeated use and friction without being easily damaged.

[0030] like Figure 1 As shown, the number of cross beams 1 is set to two, and a plurality of longitudinal beams 3 are fixedly connected between the two cross beams 1. By setting a plurality of longitudinal beams 3, the strength can be improved to adapt to high load and fatigue resistance. A plurality of hollow grooves are opened in the plurality of longitudinal beams 3. The opening of the hollow grooves can reduce the weight without affecting the strength.

[0031] Furthermore, a front plate 401 and a rear plate 402 are fixedly connected between the two cross beams 1 , and two parts of the power assembly are respectively mounted on the front plate 401 and the rear plate 402 .

[0032] Furthermore, a plurality of grab hooks 5 are fixedly connected to the outer sides of the two cross beams 1, and the grab hooks 5 are used to cooperate and fix other components.

[0033] Working principle: First, the two parts of the power assembly are installed on the front plate 401 and the rear plate 402 respectively, and then the frame assembly is installed with other components through the cooperation of the grab hook 5. When the vehicle is driving and is scratched, it will first touch the rubber sleeve 207, and then immediately drive the rotating rod 206 to rotate. Through the rotation, a part of the scratching force is deflected. While the rotating rod 206 rotates, it will drive the rotating plate 202 to rotate upward through the cooperation of the rotating block 201, and drive the multiple suspensions 204 to shrink and buffer under the cooperation of the first rotating shaft 203 and the second rotating shaft 205. In this way, by deflecting and buffering the force generated by the scratch, it can avoid damage to the frame or affecting its performance.

[0034] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
