Description

Technical fields:

[0001] This utility model relates to a rear anti-collision beam pedal assembly and an automobile body, which belongs to the field of automobile body technology. Background technology:

[0002] The rear bumper beam assembly is a key component for rear-end collision safety. In the event of a rear-end collision, the rear bumper beam assembly plays a crucial role in protecting the safety of passengers and the vehicle itself. In vehicles with higher ground clearance, the steps serve as a transitional foothold for passengers getting on and off the vehicle, providing support and facilitating their entry and exit.

[0003] like Figure 1 As shown, a traditional rear bumper beam assembly typically consists of a rear bumper beam body 100, a right rear bumper beam energy-absorbing box 200, a left rear bumper beam energy-absorbing box 300, a right rear bumper beam mounting plate 400, and a left rear bumper beam mounting plate 500. The traditional rear bumper beam assembly only serves as a rear-collision safety structural component and does not have a step support function.

[0004] Therefore, it is indeed necessary to improve existing technologies to address their shortcomings. Utility Model Content:

[0005] This utility model provides a rear bumper beam pedal assembly and a car body to solve the problems existing in the prior art. It has the functions of a traditional rear bumper beam as a rear collision safety structure and as a pedal support, providing a transitional footing area for passengers to get on and off the vehicle from the tailgate.

[0006] This utility model adopts the following technical solution: a rear bumper beam pedal assembly, including a rear bumper beam body, a left connecting plate, a middle connecting plate, and a right connecting plate. The rear bumper beam body includes a main body and a front sidewall and a rear sidewall formed by folding down from the front and rear ends of the main body. The left connecting plate, the middle connecting plate, and the right connecting plate are welded to the front sidewall of the rear bumper beam body. A spaced-apart bracket is welded to the rear sidewall of the rear bumper beam body, and the rear end of the bracket extends to the rear of the rear sidewall of the rear bumper beam body. A rear bumper is mounted on the bracket.

[0007] Furthermore, the bracket comprises two parts: the left bracket is located between the left connecting plate of the rear bumper beam and the middle connecting plate of the rear bumper beam, and the right bracket is located between the right connecting plate of the rear bumper beam and the middle connecting plate of the rear bumper beam.

[0008] Furthermore, the rear end of the connecting plate in the rear anti-collision beam is welded to the front side wall of the rear anti-collision beam body, and the upper ends of the left and right side walls of the connecting plate in the rear anti-collision beam are respectively folded outward to form a middle plate connecting part, and a first through hole is formed on the middle plate connecting part.

[0009] Furthermore, the left connecting plate of the rear anti-collision beam includes a front part and a rear part connected together. The rear end of the rear part is welded to the front side wall of the rear anti-collision beam body. The upper ends of the left and right side walls of the rear part are respectively folded outward to form side plate connecting parts, and a second through hole is formed on the side plate connecting parts.

[0010] Furthermore, a third through hole is formed at the upper end of each of the left and right sidewalls of the front part.

[0011] Furthermore, the left connecting plate and the right connecting plate of the rear bumper beam have the same structure.

[0012] Furthermore, the width of the main body is 160mm.

[0013] The present invention also adopts the following technical solution: a car body, including the aforementioned rear anti-collision beam pedal assembly.

[0014] This utility model has the following beneficial effects: The rear bumper beam pedal assembly of this utility model can simultaneously function as a rear bumper beam as a rear-collision safety structure and as a step to facilitate passenger entry and exit. By integrating the step support function into the rear bumper beam, the number of parts is reduced. Attached image description:

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] The rear bumper beam pedal assembly of this utility model includes a rear bumper beam body 1, a left connecting plate 2, a middle connecting plate 3, and a right connecting plate 4. The rear bumper beam body 1 includes a main body 10 and a front side wall and a rear side wall formed by folding down from the front end and the rear end of the main body 10. The width of the main body 10 is 160mm, which can provide a foothold for passengers and serve as a support for the rear pedal, thereby meeting the needs of passengers to get on and off the vehicle from the rear.

[0021] The left connecting plate 2, the middle connecting plate 3, and the right connecting plate 4 of the rear bumper beam are welded to the front side wall of the rear bumper beam body 1. Two spaced-apart brackets 5 are welded to the rear side wall of the rear bumper beam body 1. The rear ends of the brackets 5 extend to the rear of the rear side wall of the rear bumper beam body 1, and a rear bumper (not shown) is installed on the brackets 5.

[0022] The left bracket 5 is located between the left connecting plate 2 and the middle connecting plate 3 of the rear bumper beam, while the right bracket 5 is located between the right connecting plate 4 and the middle connecting plate 3 of the rear bumper beam.

[0023] The rear end of the connecting plate 3 in the rear anti-collision beam is welded to the front side wall of the rear anti-collision beam body 1. The upper ends of the left and right side walls of the connecting plate 3 in the rear anti-collision beam are respectively folded outward to form a middle plate connecting part 30. A first through hole 301 is formed on the middle plate connecting part 30.

[0024] The left connecting plate 2 and the right connecting plate 4 of the rear bumper beam have the same structure. The structure of the left connecting plate 2 will be described below as an example. The left connecting plate 2 includes a connected front part 20 and a rear part 21. The rear end of the rear part 21 is welded to the front sidewall of the rear bumper beam body 1. The upper ends of the left and right sidewalls of the rear part 21 are respectively folded outwards to form side plate connecting parts 210, and a second through hole 2100 is formed on the side plate connecting parts. The upper ends of the left and right sidewalls of the front part 20 are respectively formed with third through holes 201.

[0025] The rear bumper beam pedal assembly of this utility model is a welded assembly. The rear bumper beam pedal assembly is fixed to the rear of the vehicle body by tightening bolts in the Z direction at the positions of the first through hole 301 and the second through hole 2100, and by tightening bolts in the Y direction at the position of the third through hole 201.

[0026] When a rear-end collision occurs, the rear bumper beam pedal assembly experiences an X-axis force, which is transmitted to the vehicle body through the left connecting plate 2, the middle connecting plate 3, and the right connecting plate 4 of the rear bumper beam, thus protecting the safety of the occupants and preventing damage to the vehicle's main structure. When used as a step for passengers to get on and off the vehicle, the rear bumper beam pedal assembly experiences a Z-axis force, which is transmitted to the vehicle body through the left connecting plate 2, the middle connecting plate 3, and the right connecting plate 4 of the rear bumper beam, providing Z-axis support for passengers stepping on the pedals.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
