Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically a chassis structure for automobiles. Background Technology

[0002] The car chassis is an important structural component used to support and install the car engine and its various parts. The function of the chassis is to support and install the car engine and its various parts and assemblies, form the overall shape of the car, receive the power from the engine, enable the car to move, and ensure normal driving.

[0003] Automobile chassis typically incorporate a buffer structure for shock absorption or collision protection. For example, a noise reduction device for an automobile chassis, disclosed in CN 115571022A, includes a top connecting plate, a mounting plate, bolts, a noise reduction partition, a vacuum sound insulation plate, a shock-absorbing column, a buffer pad, and a protective base plate. The shock-absorbing column is located between the mounting plate and the protective base plate. The upper end of the shock-absorbing column is fixed to the lower part of the mounting plate, and the lower end of the shock-absorbing column is fixed to the upper surface of the protective base plate. The shock-absorbing column includes a body, an inner plate, a piston, a spring, and a fixing column. The inner plate is fixed to the center of the body, and through holes are provided on both sides of the inner plate, forming a cavity above the inner plate. This cavity is filled with hydraulic oil. The piston is located above the inner plate, and the lower part of the piston is fixed to the upper part of the fixing column via a connecting rod. A spring is fixed between the fixing column and the inner plate, and the fixing column is fixed to the upper side of the protective base plate. The car chassis uses springs for shock absorption, and while springs are inherently elastic and do have a cushioning effect, they also generate a reaction force after being subjected to force, so the shock absorption effect cannot be guaranteed. Utility Model Content

[0004] This utility model discloses a chassis structure for automobiles to solve the technical problem of shock absorption and damping.

[0005] To solve the above-mentioned technical problems, the present invention proposes the following optimized technical solution:

[0006] A chassis structure for an automobile includes a chassis frame, two front connecting structures, and two rear connecting structures. A reinforcing frame is provided at the top front end of the chassis frame. The two front connecting structures are located on both sides of the front end of the chassis frame and are used to connect the front wheels. Each front connecting structure has a front airbag, which connects the front connecting structure and the reinforcing frame. The two rear connecting structures are located on both sides of the rear end of the chassis frame and are used to connect the rear wheels. Each rear connecting structure has a rear airbag, which connects the rear connecting structure and is used to support the vehicle body.

[0007] Furthermore, the base frame includes two vertical rods, multiple horizontal rods, and two widening strips. The two vertical rods are arranged parallel to each other, the multiple horizontal rods are evenly spaced on the two vertical rods, and the two widening strips are respectively arranged on both sides of the two vertical rods. The two ends of the horizontal rods are respectively connected to the two widening strips.

[0008] Furthermore, protective strips are provided at both ends of the vertical rod.

[0009] Furthermore, the front connection structure includes a first U-shaped component and two first connecting components. The middle part of the first U-shaped component is used to connect the front wheel. One end of each of the two first connecting components is rotatably connected to both ends of the first U-shaped component, and the other end is rotatably connected to the base frame and the reinforcing frame.

[0010] Furthermore, the first connector is V-shaped, with the middle part of the first connector rotatably connected to the first U-shaped component and both ends rotatably connected to the reinforcing frame.

[0011] Furthermore, the rear connection structure includes a second U-shaped member and a second connecting member. The middle part of the second U-shaped member is used to connect to the rear wheel. One end of the second connecting member is connected to one end of the second U-shaped member and the other end is connected to the chassis. The other end of the second U-shaped member is connected to one end of the rear airbag.

[0012] Furthermore, the second connector is V-shaped, with the middle part of the second connector rotatably connected to the second U-shaped component and both ends rotatably connected to the base frame.

[0013] Furthermore, the first U-shaped component is vertically arranged, and the two first connecting components are stacked one on top of the other.

[0014] Furthermore, one end of the front buffer airbag is rotatably connected to the first connecting piece below, and the other end is rotatably connected to the reinforcing frame.

[0015] The present invention has the following advantages over the prior art:

[0016] The automotive chassis structure provided by this utility model has front and rear buffer airbags respectively installed in the front and rear connecting structures. The front buffer airbag is used to connect the reinforcement frame and the front connecting structure, and has a buffering effect between the front wheels and the chassis. Specifically, when the front wheels or chassis are impacted, the front buffer airbag has a counteracting effect on the force, thereby achieving shock absorption and collision protection. The rear buffer airbag is used to connect the chassis and the vehicle body. When the chassis is impacted, the rear buffer airbag counteracts the force on the chassis, preventing the vehicle body from vibrating. Overall, it plays a dual role in counteracting the force, greatly improving shock absorption and collision protection. Attached Figure Description

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] See Figures 1-4 A chassis structure for an automobile includes a chassis frame 1, two front connecting structures 2, and two rear connecting structures 3. A reinforcing frame 4 is provided at the top front end of the chassis frame 1. The two front connecting structures 2 are located on both sides of the front end of the chassis frame 1 and are used to connect the front wheels 15. Each front connecting structure 2 is equipped with a front airbag 5. The front airbag 5 connects the front connecting structure 2 and the reinforcing frame 4, and provides a buffering effect between the front wheels 15 and the chassis frame 1. Specifically, the vibration generated by an impact on the front wheels 15 or the chassis is transmitted to the front airbag 5. The airbag 5 cancels out the force, thus eliminating the force and achieving the effect of shock absorption and collision prevention. The two rear connecting structures 3 are set on both sides of the rear end of the chassis 1 and are used to connect the rear wheels 16. The rear connecting structure 3 is equipped with a rear buffer airbag 6. The rear buffer airbag 6 is connected to the rear connecting structure 3 and is used to support the vehicle body. The rear buffer airbag 6 has a buffering effect between the chassis 1 and the vehicle body. That is, for the vehicle body, the front buffer airbag 5 and the rear buffer airbag 6 provide double buffering, which greatly eliminates vibration and provides better shock absorption and collision prevention.

[0024] In this embodiment, the chassis 1 includes two vertical rods 7, multiple horizontal rods 8, and two widening strips 9. The two vertical rods 7 are arranged parallel to each other, and the multiple horizontal rods 8 are evenly spaced on the two vertical rods 7. The two widening strips 9 are respectively located on both sides of the two vertical rods 7, and the two ends of the horizontal rods 8 are respectively connected to the two widening strips 9. The two vertical rods 7 and the multiple horizontal rods 8 form a simple yet highly rigid support structure. The widening strips 9 are used to widen the middle part of both sides of the chassis 1 to match the shape of the vehicle body.

[0025] In this embodiment, protective strips 10 are provided at both ends of the vertical rod 7 to prevent collisions.

[0026] In this embodiment, the front connection structure 2 includes a first U-shaped member 11 and two first connecting members 12. The middle part of the first U-shaped member 11 is used to connect the front wheel 15. One end of each of the two first connecting members 12 is rotatably connected to both ends of the first U-shaped member 11, and the other end is rotatably connected to the base frame 1 and the reinforcing frame 4, respectively. The first U-shaped member 11 has a U-shaped structure, which can withstand greater pressure in the vertical direction. Furthermore, the U-shaped structure has a certain curvature, which allows it to resiliently offset some stress when subjected to a strong impact, making it more reliable than simple rigid bearing. Specifically, the first U-shaped member 11 is vertically arranged, and the two first connecting members 12 are stacked vertically. This connection method makes the connection between the front wheel 15 and the base frame 1 more stable. The first U-shaped member 11 and the first connecting members 12 are rotatably connected, meaning they can adaptably rotate when vibration occurs, avoiding any impact on rigidity.

[0027] In this embodiment, the first connector 12 is V-shaped, with the middle part of the first connector 12 rotatably connected to the first U-shaped member 11 and both ends rotatably connected to the reinforcing frame 4. The first V-shaped member is designed with an enlarged surface area to increase load-bearing capacity, resulting in a higher overall load-bearing capacity.

[0028] In this embodiment, the rear connection structure 3 includes a second U-shaped member 13 and a second connecting member 14. The middle part of the second U-shaped member 13 is used to connect to the rear wheel 16. One end of the second connecting member 14 is connected to one end of the second U-shaped member 13, and the other end is connected to the chassis 1. The other end of the second U-shaped member 13 is connected to one end of the rear airbag 6. The second U-shaped member 13 has a U-shaped structure. In the vertical direction, the U-shaped structure can withstand greater pressure, and the U-shaped structure has a certain curvature, which can toughly offset some stress when subjected to a strong impact, making it more reliable than simple rigid pressure bearing.

[0029] In this embodiment, the second connector 14 is V-shaped, with the middle part of the second connector 14 rotatably connected to the second U-shaped member 13 and both ends rotatably connected to the base frame 1. The second V-shaped member is designed with an enlarged surface area to increase load-bearing capacity, resulting in a higher overall load-bearing capacity.

[0030] In this embodiment, one end of the front airbag 5 is rotatably connected to the first connecting member 12 below, and the other end is rotatably connected to the reinforcing frame 4. When the base frame 1 or the front wheel 15 is subjected to force transmitted to the front airbag 5, the front airbag 5 can adapt to the direction of the force and rotate accordingly, thus avoiding any impact on its rigidity.

[0031] The aforementioned rotatable connections all involve connecting lugs and connecting strips with through holes passing through a pivot shaft to achieve a rotatable connection.

[0032] The above description is merely a specific embodiment of the present invention, enabling those skilled in the art to understand or implement the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features claimed herein.
