Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, specifically a rear bumper and frame for a dump truck. Background Technology

[0002] Commercial vehicles are automobiles primarily designed and technically designed for transporting people and goods. They mainly include five categories: buses, trucks, semi-trailer tractors, incomplete bus vehicles, and incomplete truck vehicles. Specific classifications are as follows: Buses: Commercial vehicles used for transporting people, including public buses, long-distance coaches, airport shuttle buses, etc.; Trucks: Commercial vehicles used for transporting goods, which can be divided into mini-trucks, light trucks, medium trucks, and heavy trucks based on load capacity and function. Heavy trucks can be further subdivided into cargo trucks, dump trucks, and special-purpose vehicles; Semi-trailer tractors: Commercial vehicles used for towing semi-trailers, typically used in long-distance logistics or port logistics scenarios; Incomplete bus vehicles and incomplete truck vehicles: These two types of vehicles are usually based on the chassis of a bus or truck, requiring the user to install the body and superstructure themselves.

[0003] Car bumpers are safety devices that absorb and mitigate external impacts, protecting the front and rear of the vehicle. Passenger cars typically have plastic front and rear bumpers, commonly referred to as plastic bumpers. Commercial vehicles, especially freight vehicles, however, use traditional metal bumpers to better suit their commercial vehicle characteristics.

[0004] Currently, the rear bumpers installed on trucks are rigidly connected, and the rear bumpers are too high off the ground. When a car or other vehicle rear-ends a truck, it can easily cause injury or death.

[0005] Chinese patent CN103640538A discloses an adjustable rear bumper device for trucks. Although the rear bumper adopts an adjustable design, because the hydraulic cylinder is connected to a rocker arm, the rocker arm can adjust the vertical height of the bumper. In the event of an accident, the bumper will rotate around a relevant axis, so when people come into contact with the bumper, it is still a rigid contact, which does not solve the problem of reducing personal injury. Utility Model Content

[0006] To address the issue that bumpers, while enhancing their own safety, lack the ability to cushion rear-end collisions, this utility model provides a rear bumper and frame for dump trucks.

[0007] This utility model is achieved through the following technical solution:

[0008] A rear bumper for a dump truck includes a mounting bracket, the mounting bracket including a vertical support plate and a horizontal mounting plate connected to the support plate; the vertical support plate has an outwardly extending buffer on its side away from the horizontal mounting plate;

[0009] Two horizontal mounting plates are provided, which are respectively connected to the two ends of the vertical support plate in the horizontal direction. Two compression spring assemblies are connected to the end of the horizontal mounting plate away from the vertical support plate. The two compression spring assemblies are arranged vertically at intervals and can push the horizontal mounting plate to form elastic support in the horizontal direction after the vertical support plate is subjected to force.

[0010] The buffer component and compression spring assembly can form a two-stage buffer for rear-end collisions, which greatly improves the safety of the rear bumper in the event of a rear-end collision. While improving the vehicle's own safety, it also provides a certain buffer margin for protection against slow rear-end collisions.

[0011] A further improvement of this utility model is that the vertical support plate is provided with a storage groove that can accommodate the installation of the buffer component.

[0012] A further improvement of this utility model is that the above-mentioned buffer is a soft material with resilience and integral molding.

[0013] A further improvement of this invention is that the aforementioned buffer includes an outer bag and a non-Newtonian fluid disposed within the outer bag.

[0014] A further improvement of this utility model is that an upper fixing plate is connected between the horizontal mounting plate and the compression spring assembly. The upper fixing plate extends vertically, and the compression spring assembly is connected to the upper part of the upper fixing plate, while the horizontal mounting plate is connected to the lower part of the upper fixing plate.

[0015] A further improvement of this utility model is that the upper fixing plate is connected to the horizontal mounting plate via a lower inclined connecting plate.

[0016] A further improvement of this utility model is that the aforementioned inclined connecting plate is detachably connected to the horizontal mounting plate via a locking member. The horizontal mounting plate is provided with multiple sets of locking mounting holes in the horizontal direction that can be adapted to the locking member. The locking member can be adapted to different locking mounting holes to adjust the outward extension distance of the horizontal mounting plate.

[0017] A further improvement of this utility model is that the lower part of the vertical support plate is connected to the horizontal mounting plate, and the upper part of the vertical support plate is connected to the lower inclined connecting plate through a horizontal support rod.

[0018] A chassis includes a chassis body, on which a rear bumper of a dump truck is mounted; the longitudinal beams of the chassis body are provided with two guide grooves arranged vertically and extending horizontally to accommodate the compression spring assembly.

[0019] A further improvement of this utility model is that the above-mentioned compression spring assembly includes a compression spring body and a slider. The compression spring body is horizontally installed in the guide groove along the axis. The slider is slidably disposed in the guide groove and connected to one end of the compression spring body near the vertical support plate. The slider protrudes from the outer side of the longitudinal beam of the frame body and is connected to the upper fixing plate through the second locking member.

[0020] As can be seen from the above technical solutions, the beneficial effects of this utility model are: the buffer component and the compression spring assembly can form a two-stage buffer for rear-end collisions involving vehicles approaching from behind, which greatly improves the safety of the rear bumper when rear-end collisions involving vehicles approaching from behind. While improving the vehicle's own safety, it also provides protection with a certain buffer margin for slow rear-end collisions involving vehicles approaching from behind.

[0025] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0026] Example 1:

[0027] As shown in the figure, a rear bumper for a dump truck includes a mounting frame 2. The mounting frame 2 includes a vertical support plate 24 and a horizontal mounting plate 23 connected to the support plate. The vertical support plate 24 has an outwardly extending buffer 3 on its side away from the horizontal mounting plate 23. The vertical support plate 24 has a storage groove for accommodating the buffer 3. The buffer 3 is a soft material with resilience and integral molding, such as rubber or a high-hardness sponge.

[0028] Two horizontal mounting plates 23 are provided, each connected to one end of the vertical support plate 24 in the horizontal direction. Two compression spring assemblies are connected to the end of each horizontal mounting plate 23 facing away from the vertical support plate 24. The two compression spring assemblies are spaced apart vertically and can push the horizontal mounting plates 23 along the horizontal direction to form elastic support when the vertical support plate 24 is subjected to force. The buffer member 3 and the compression spring assemblies form a two-stage buffer against rear-end collisions, significantly improving the safety of the rear bumper in such situations. While enhancing the vehicle's own safety, it also provides a certain buffer margin for protection against slow rear-end collisions.

[0029] An upper fixing plate 21 connects the horizontal mounting plate 23 to the compression spring assembly. The upper fixing plate 21 extends vertically, with the compression spring assembly connected to its upper part and the horizontal mounting plate 23 connected to its lower part. The upper fixing plate 21 is connected to the horizontal mounting plate 23 via a lower inclined connecting plate 22. The lower inclined connecting plate 22 connects the upper fixing plate 21 and the horizontal mounting plate 23, which can improve the support strength of the upper fixing plate 21 for the horizontal mounting plate 23, and also helps to improve the strength of the overall support structure.

[0030] The lower inclined connecting plate 22 is detachably connected to the horizontal mounting plate 23 via a locking member. The horizontal mounting plate 23 has multiple sets of locking mounting holes in the horizontal direction that can be adapted to the locking member. The locking member can be adapted to different locking mounting holes to adjust the outward extension distance of the horizontal mounting plate 23. The rearward extension distance of the vertical support plate 24 can be selected according to the actual situation.

[0031] The lower part of the vertical support plate 24 is connected to the horizontal mounting plate 23, and the upper part of the vertical support plate 24 is connected to the lower inclined connecting plate 22 via a horizontal support rod 25. Specifically, the lower inclined connecting plate 22 is provided with a guide clamping plate assembly. The guide clamping plate assembly provides adjustable and fixed support for the horizontal support rod 25 between the horizontal mounting plate 23 and the lower inclined connecting plate 22. This allows for adjustment in the extension direction of the horizontal mounting plate 23. The guide clamping plate assembly provides coordinated support for the horizontal support rod 25 to improve the stability of the vertical support plate 24.

[0032] Example 2:

[0033] Everything else remains the same. The buffer 3 includes an outer bag and a non-Newtonian fluid disposed within the outer bag.

[0034] Example 3;

[0035] A vehicle frame includes a frame body 1, on which the rear bumper of the dump truck is mounted; the outer side of the longitudinal beam of the frame body 1 is provided with two guide grooves 11 arranged vertically and extending horizontally to accommodate the compression spring assembly.

[0036] The compression spring assembly includes a compression spring body 14 and a slider 12. The compression spring body 14 is horizontally installed in the guide groove 11 with its axis as the center line. The slider 12 is slidably disposed in the guide groove 11 and connected to one end of the compression spring body 14 near the vertical support plate 24. The slider 12 protrudes from the outer side of the longitudinal beam of the frame body 1 and is connected to the upper fixing plate 21 through the locking member 2 13.

[0037] The longitudinal beam of the frame body 1 is also provided with a first limiting plate 15 and a second limiting plate 16, which are respectively disposed at both ends of the guide groove 11. When the buffer 3 is impacted, causing the slider 12 to exert a large-amplitude rapid compression on the compression spring body 14 in the guide groove 11, the first limiting plate 15 can contact the slider 12 to form a block; the second limiting plate 16 can contact the slider 12 when the compression spring body 14 rebounds to form a block.

[0038] The rear bumper and frame of the dump truck described in this utility model can form a two-stage buffer for rear-end collisions with vehicles approaching from behind, through the buffer component and compression spring assembly. This significantly improves the safety of the rear bumper in the event of a rear-end collision with a vehicle approaching from behind. While improving the vehicle's own safety, it also provides a certain buffer margin for protection against slow rear-end collisions with vehicles approaching from behind.
