Description

Technical Field

[0001] This utility model relates to the field of anti-collision beam technology, specifically to a safety protection buffer structure for the main cab. Background Technology

[0002] The driver's cab safety protection buffer structure is the front anti-collision beam structure of a car. The anti-collision beam is a device used to reduce the impact energy absorbed when a vehicle is involved in a collision. It consists of a main beam, an energy-absorbing box, and a mounting plate that connects to the car. Both the main beam and the energy-absorbing box can effectively absorb the impact energy when the vehicle is involved in a low-speed collision, minimizing the damage to the longitudinal beams of the vehicle body. In this way, it plays its role in protecting the vehicle.

[0003] Most existing automotive front bumper beams are closed cavities with springs, rubber, and other materials to help absorb kinetic energy. Their structures are relatively complex, costly, and have only average impact protection.

[0004] In summary, the existing chassis-type front anti-collision beam structure for automobiles has the following problems when in use: it relies on springs, rubber, and other materials to help absorb kinetic energy, resulting in a relatively complex structure, high cost, and only average anti-collision effect. Utility Model Content

[0005] The purpose of this utility model is to provide a safety protection buffer structure for the driver's cab, so as to solve the technical problems of most existing front anti-collision beam structures of automobiles relying on springs, rubber and other materials to help absorb kinetic energy, which are relatively complex, costly and have a general anti-collision effect.

[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0007] A safety protection buffer structure for the main driver's cab includes:

[0008] An energy-absorbing component, comprising two sets of anti-collision beams welded together at their upper and lower ends, wherein the anti-collision beams comprise two sets of symmetrically distributed protrusions and a recess disposed between the protrusions;

[0009] The energy-absorbing assembly also includes recessed arc grooves formed on the outer wall of the protrusion and the inner wall of the depression, an energy-absorbing frame body disposed inside the protrusion, with the upper and lower ends of the energy-absorbing frame body being brazed and fixed to the end face of the recessed arc groove, and auxiliary plates symmetrically disposed on both sides of the energy-absorbing frame body, with the two ends of the auxiliary plates being brazed and fixed to both sides of the energy-absorbing frame body and the side wall of the protrusion, respectively.

[0010] Preferably, the cross-sectional shape of the anti-collision beam is U-shaped.

[0011] Preferably, the cross-sectional shape of the energy-absorbing frame is a parallelogram.

[0012] Preferably, the cross-sectional shape of the auxiliary plate is wavy.

[0013] Preferably, a fixing plate is provided on one side of the energy-absorbing component, and the fixing plate is fixedly connected to the energy-absorbing component by bolts.

[0014] Preferably, one side of the fixing plate is provided with a C-shaped plate 1 and a C-shaped plate 2 that are interlocked, and the width of the C-shaped plate 1 is greater than the width of the C-shaped plate 2. The C-shaped plate 1 and the C-shaped plate 2 are fixedly connected by rivets.

[0015] Preferably, the first and second shaped plates are provided with a fixing plate two at the ends away from the fixing plate one.

[0016] Preferably, a fixing hole is provided through the central area of ​​the fixing plate 2.

[0017] Preferably, the four corners of the fixing plate are symmetrically provided with fixing holes.

[0018] Preferably, the protective buffer structure is made entirely of aluminum alloy.

[0019] The beneficial effects of this utility model are:

[0020] 1. In this utility model, the cross-section of the anti-collision beam is U-shaped, and its recessed part is distributed away from the impact direction of the device, which ensures that the anti-collision beam can deform smoothly when it is impacted. The U-shaped design not only enhances the structural strength of the anti-collision beam, but also provides it with additional energy absorption space. The recessed arc groove, through its special arc design, can more effectively guide and disperse stress during the collision, so that the anti-collision beam can collapse towards the inside of the protrusion, thereby increasing the energy absorption efficiency. When the protrusion collapses inward, the parallelogram-shaped energy-absorbing frame set inside the protrusion can undergo controllable deformation, thereby further absorbing a large amount of energy.

[0021] 2. In this utility model, the auxiliary plate has a wavy cross-sectional shape, and its two ends are brazed and fixed to the two sides of the energy-absorbing frame and the side wall of the protrusion, respectively. When the anti-collision beam and the energy-absorbing frame deform, the auxiliary plate will also collapse or stretch accordingly, thereby playing an auxiliary buffering effect and further enhancing the energy absorption capacity of the structure.

[0027] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0028] like Figure 1-3 As shown, a safety protection buffer structure for the main driver's cab includes...

[0029] The energy-absorbing component includes two sets of anti-collision beams 1 welded together at their upper and lower ends. The anti-collision beam 1 includes two sets of symmetrically distributed protrusions 101 and a recess 102 disposed between the protrusions 101. The cross-sectional shape of the anti-collision beam 1 is U-shaped.

[0030] The energy-absorbing assembly also includes recessed arc grooves 8 formed on the outer wall of the protrusion 101 and the inner wall of the recess 102, an energy-absorbing frame 9 disposed inside the protrusion 101, and the upper and lower ends of the energy-absorbing frame 9 being brazed and fixed to the end faces of the recessed arc grooves 8, respectively. The cross-sectional shape of the energy-absorbing frame 9 is a parallelogram. Auxiliary plates 10 are symmetrically arranged on both sides of the energy-absorbing frame 9, and the two ends of the auxiliary plates 10 are brazed and fixed to the sides of the energy-absorbing frame 9 and the side walls of the protrusion 101, respectively. The cross-sectional shape of the auxiliary plates 10 is wavy. The anti-collision beam 1, as the main structure of the device, provides installation positions for other structures and ensures the stability of other structures during operation. The cross-section of the anti-collision beam 1 is U-shaped, and its recessed portion 102 is distributed away from the impact direction of the device, thereby ensuring that the anti-collision beam 1 can deform smoothly when it encounters an impact, thus achieving the effect of energy absorption. Therefore, the U-shaped design not only enhances the structural strength of the anti-collision beam 1, but also... In addition to providing additional energy absorption space, the recessed arc groove 8, through its special arc design, can more effectively guide and disperse stress during a collision, allowing the anti-collision beam 1 to collapse towards the inside of the protrusion 101, thereby increasing energy absorption efficiency. When the protrusion 101 collapses inward, the parallelogram-shaped energy-absorbing frame 9 set inside the protrusion 101 can undergo controllable deformation, thereby further absorbing a large amount of energy. The upper and lower ends of the energy-absorbing frame 9 are respectively brazed and fixed to the end face of the recessed arc groove 8, further ensuring the integrity and stability of the protrusion 101. The auxiliary plate 10 has a wavy cross-section, and its two ends are respectively brazed and fixed to the sides of the energy-absorbing frame 9 and the side wall of the protrusion 101. When the anti-collision beam 1 and the energy-absorbing frame 9 deform, the auxiliary plate 10 will also collapse or stretch accordingly, thereby playing an auxiliary buffering role and further enhancing the energy absorption capacity of the structure.

[0031] In this embodiment, specifically, a fixing plate 2 is provided on one side of the energy-absorbing component, and the fixing plate 2 is fixedly connected to the energy-absorbing component by bolts. On one side of the fixing plate 2, two interlocking C-shaped plates 3 and 4 are provided, with the width of the C-shaped plate 3 being greater than the width of the C-shaped plate 4. The C-shaped plates 3 and 4 are fixedly connected by rivets. A fixing plate 5 is provided at the end of the C-shaped plates 3 and 4 away from the fixing plate 2. A fixing hole 6 is provided through the center of the fixing plate 5, and fixing holes 7 are symmetrically provided at the four corners of the fixing plate 5. The fixing plate 2 is located on one side of the energy-absorbing component and is fixedly connected to the energy-absorbing component by bolts. The components are fixedly connected, providing a stable support point for the entire structure. The C-shaped plate 3 and the C-shaped plate 4 are interlocked to form an adjustable connection, which ensures the firmness of the connection while allowing for some fine-tuning to adapt to different installation requirements. The width of the C-shaped plate 3 is greater than that of the C-shaped plate 4. This design helps to disperse stress and improve the durability of the connection. In the event of an impact, the C-shaped plate 3 and the C-shaped plate 4 can deform independently, thereby achieving a good energy absorption effect. The fixing holes 6 and 7 on the fixing plate 5 are used to firmly install the entire protective buffer structure at the front end of the vehicle's main cab.

[0032] In this embodiment, the protective buffer structure is made of aluminum alloy. Aluminum alloy has good energy absorption effect and is lightweight. Using aluminum alloy as the protective buffer structure reduces the structural weight and improves the vehicle's fuel economy.

[0033] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] The working principle of this utility model is as follows: First, the fixing holes 6 and 7 on the fixing plate 2 are used to firmly install the entire protective buffer structure at the front end of the vehicle's driver's cab. When the vehicle collides, the protective buffer structure is the first to be impacted. The impact force first acts on the anti-collision beam 1. The concave design and recessed arc groove 8 of the anti-collision beam 1 begin to play their role. The recessed arc groove 8 can guide the deformation of the anti-collision beam 1, thereby guiding and dispersing stress. At the same time, the energy-absorbing frame 9 deforms under the impact force and absorbs a large amount of energy. The auxiliary plate 10 also participates in the energy absorption process, further enhancing the stability of the structure. Subsequently, the C-shaped plate 3 and C-shaped plate 4 also collapse under the impact force, further absorbing energy.

[0035] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
