Description

Technical Field

[0001] This utility model belongs to the field of automotive bracket technology, and in particular relates to an automotive mounting bracket. Background Technology

[0002] Anti-collision beams are protective components used to absorb collision energy when a vehicle is involved in a collision. They are connected to the longitudinal beams of the vehicle frame via mounting brackets.

[0003] The mounting brackets currently used for anti-collision beams have the following defects: poor buffering performance and low safety. When the anti-collision beam is subjected to a large impact force, the mounting bracket cannot effectively buffer the impact force. The mounting bracket will deform and be damaged, and most of the impact force will be transmitted to the longitudinal beams of the vehicle frame, which will cause certain damage to the vehicle body. In severe cases, it will also endanger the health of the people inside the vehicle. Summary of the Invention

[0004] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art and to provide a car mounting bracket with novel structure, impact resistance, good cushioning performance, durability and strong practicality.

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

[0006] An automotive mounting bracket includes: a base for connecting to a vehicle frame longitudinal beam; and a beam mounting plate for connecting to a crash beam. The bracket is characterized by: an elastic buffer assembly between the base and the beam mounting plate; a buffer plate on the back of the beam mounting plate with protrusions and corresponding grooves; and a transverse through-slot filled with foam blocks. This automotive mounting bracket features a novel structure, is impact-resistant, provides excellent cushioning, is durable, and highly practical.

[0007] Furthermore, the elastic buffer assembly includes a first housing, a second housing, and a buffer spring. The first housing is mounted on the beam mounting plate, and the second housing is mounted on the base. The first housing and the second housing are slidably connected, and the buffer spring is located between the first housing and the second housing. When the steel beam is impacted, the beam mounting plate moves the first housing closer to the second housing, thereby compressing the buffer spring. The buffer spring absorbs the impact energy and generates a rebound force to prevent the first housing from continuing to move, thus stabilizing the beam mounting plate and minimizing the impact energy received by the frame.

[0008] Furthermore, the beam mounting plate has a concave structure, with the bottom of the groove connecting to the beam mounting plate, and the opening of the concave structure serving as a locking slot. This concave design improves the energy absorption effect of the beam mounting plate, making it more impact-resistant.

[0009] Furthermore, the first box body is fixedly connected to the top of the concave structure via a fixing plate. The fixing plate binds the two convex tops of the concave structure together, which can limit its lateral deformation, improve the structural stability of the beam mounting plate, and extend its service life.

[0010] Furthermore, the fixing plate is securely connected to the beam mounting plate with screws. This ensures reliable fixation, and the first box is easy to assemble and disassemble, allowing for immediate use and flexibility.

[0011] Furthermore, both ends of the buffer spring are equipped with fixing blocks, which are fixedly connected to the first and second housings by screws. This ensures reliable fixation, easy disassembly and assembly of the buffer spring, convenient replacement, and flexible use.

[0012] Furthermore, foam strips are embedded in the slot, with protrusions located between the foam strips. The foam strips on both sides simultaneously abut against the protrusions, which can limit the left and right displacement of the buffer plate and improve the installation stability of the buffer plate. The foam strips fill the empty part of the slot and play an internal support role for the beam mounting plate, which can resist the deformation of the beam mounting plate into the slot.

[0013] Furthermore, the buffer plate is provided with grooves corresponding to the protrusions. By embedding the protrusion of the next buffer plate into the groove of the previous buffer plate, multiple buffer plates can be stacked together to form a buffer plate assembly. This assembly can adapt to the actual distance between the beam mounting plate and different vehicle frames. The buffer plate assembly is in full contact with the vehicle frame, avoiding gaps that would affect the buffering effect.

[0014] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0015] 1. When the steel beam is impacted, the buffer plate provides support to the beam mounting plate, resists the deformation of the beam mounting plate, and avoids the gap between the beam mounting plate and the frame, which makes it easy to be deformed by pressure. The buffer plate can also absorb impact energy, thereby reducing the impact energy transmitted to the frame.

[0016] 2. When installing the buffer plate, insert the protrusion into the slot to achieve quick positioning of the buffer plate on the beam mounting plate. The operation is simple and the replacement is convenient. The protrusion is in close contact with the inner wall of the slot, and there is a large friction force, so the buffer plate is not easy to fall off freely.

[0017] 3. The protrusion of the rear buffer plate is embedded into the groove of the front buffer plate, which allows multiple buffer plates to be stacked together to form a buffer plate assembly. This assembly can adapt to the actual distance between the beam mounting plate and different vehicle frames. The buffer plate assembly is in full contact with the vehicle frame, avoiding gaps that would affect the buffering effect. Attached Figure Description

Detailed Implementation

[0027] like Figures 1 to 7 As shown, this utility model discloses an automotive mounting bracket, comprising: a base 1, a beam mounting plate 2, and a buffer plate 3. The base 1 has mounting through holes 4, through which bolts are inserted to connect and fix the base 1 to the longitudinal beam of the vehicle frame. The beam mounting plate 2 has fixing through holes 5, through which bolts are inserted to connect and fix the beam mounting plate 2 to the anti-collision steel beam.

[0028] An elastic buffer assembly is provided between the base 1 and the beam mounting plate 2. The elastic buffer assembly includes a first housing 6, a second housing 7, and a buffer spring 8. The first housing 6 is fixed on the beam mounting plate 2, and the second housing 7 is fixed on the base 1. The first housing 6 and the second housing 7 are slidably connected. Both ends of the buffer spring 8 are provided with fixing blocks 9. The fixing blocks 9 are fixedly connected to the first housing 6 and the second housing 7 by screws, which is reliable. The buffer spring 8 is easy to disassemble and replace, and can be used immediately after installation, which is flexible and convenient.

[0029] When the steel beam is impacted, the beam mounting plate 2 moves the first box 6 closer to the second box 7, which in turn compresses the buffer spring 8. The buffer spring 8 absorbs the impact energy and generates a rebound force to prevent the first box 6 from continuing to move, thus stabilizing the beam mounting plate 2 and minimizing the impact energy on the frame.

[0030] The beam mounting plate 2 adopts a double-layer steel plate design, which is formed by roll forming, creating a concave structure. The bottom of the groove in the concave structure connects to the beam mounting plate 2. The concave structure design improves the energy absorption effect of the beam mounting plate 2, making it more impact-resistant.

[0031] The first housing 6 is fixedly connected to the top of the concave structure via a fixing plate 10. The fixing plate 10 binds the two convex tops of the concave structure together, which can limit its lateral deformation, improve the structural stability of the beam mounting plate 2, and extend its service life. The fixing plate 10 is fixedly connected to the beam mounting plate 2 with screws, which is reliable. The first housing 6 is easy to assemble and disassemble, and can be used immediately after installation, making it flexible and convenient.

[0032] The two transverse through slots 11 of the beam mounting plate 2 are filled with foam blocks 12. The foam blocks 12 are made of polypropylene foam. The foam blocks 12 provide internal support for the beam mounting plate 2, resist the lateral deformation of the two protrusions of the beam mounting plate 2, and improve the structural stability of the beam mounting plate 2.

[0033] The buffer plate 3 is located on the back of the beam mounting plate 2, between the frame and the beam mounting plate 2. The buffer plate 3 can be made of polypropylene foam material, offering good cushioning performance and low operating costs. When the steel beam is impacted, the buffer plate 3 provides support to the beam mounting plate 2, resisting deformation and preventing gaps between the beam mounting plate 2 and the frame that could easily lead to deformation under pressure. The buffer plate 3 also absorbs impact energy, thereby reducing the impact energy transmitted to the frame.

[0034] The concave structure has an opening called a slot 13, and a protrusion 14 corresponding to the slot 13 is provided on one side of the buffer plate 3. The protrusion 14 is inserted into the slot 13 to achieve quick positioning of the buffer plate 3 on the beam mounting plate 2. The operation is simple and the replacement is convenient. The protrusion 14 is in close contact with the inner wall of the slot 13, and there is a large friction force, so the buffer plate 3 is not easy to fall off freely.

[0035] The other side of the buffer plate 3 is provided with a groove 15 corresponding to the protrusion 14. By inserting the protrusion 14 of the next buffer plate 3 into the groove 15 of the previous buffer plate 3, multiple buffer plates 3 can be stacked together to form a buffer plate 3 assembly. This assembly can adapt to the actual distance between the beam mounting plate 2 and different vehicle frames. The buffer plate 3 assembly is in full contact with the vehicle frame, avoiding gaps that would affect the buffering effect.

[0036] Foam strips 16 are embedded in the slot 13. The foam strips 16 are made of polypropylene foam. The protrusions 14 are located between the foam strips 16. The foam strips 16 on both sides simultaneously abut against the protrusions 14, which can limit the left and right displacement of the buffer plate 3 and improve the installation stability of the buffer plate 3. The foam strips 16 fill the empty part of the slot 13 and play an internal support role for the beam mounting plate 2, which can resist the deformation of the beam mounting plate 2 into the slot 13.

[0037] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
