Description

Technical Field

[0001] This utility model relates to the field of automotive engine technology, and more specifically, to a welded assembly of the side beam of an automotive engine compartment. Background Technology

[0002] The engine compartment, located at the front of a car, is typically an enclosed space used to install and protect the engine and its related components. It generally includes the engine, air filter, battery, exhaust system, throttle body, coolant reservoir, relay box, brake booster pump, accelerator cable, windshield washer fluid reservoir, brake fluid reservoir, fuses, and more. Beams are installed on both sides of the engine compartment to support it and prevent damage from impacts.

[0003] A search revealed that utility model patent CN220615964U discloses an engine compartment side beam assembly and a vehicle, comprising: an engine compartment side beam assembly including an engine compartment side beam body, the engine compartment side beam body including an engine compartment side beam wall panel, a first engine compartment side beam side panel and a second engine compartment side beam side panel, the first engine compartment side beam side panel, the second engine compartment side beam side panel and the engine compartment side beam wall panel together forming a rectangular structure with a cross-section open on one side; a side beam reinforcement member, the side beam reinforcement member including a reinforcement member wall panel, a first reinforcement member side panel and a second reinforcement member side panel, the engine compartment side beam wall panel being fitted with the reinforcement member wall panel; a first connecting portion is formed on the first reinforcement member side panel, a second connecting portion is formed on the second reinforcement member side panel, the first connecting portion is connected to the first engine compartment side beam side panel, and the second connecting portion is connected to the second engine compartment side beam side panel. This patent can solve the problem of poor energy absorption performance of engine compartment side beam assemblies in the prior art. However, the aforementioned patent has the following shortcomings: It achieves energy absorption and dissipation by disconnecting the first connecting part from the first engine compartment side beam and the second connecting part from the second engine compartment side beam; when the connecting part and the engine compartment side beam are securely connected, it is inconvenient to disconnect them; when the connecting part and the engine compartment side beam are not securely connected, it affects the connection strength between the engine compartment side beam body and the side beam reinforcement, resulting in poor practicality. Therefore, we propose a welded assembly for automotive engine compartment side beams. Utility Model Content

The internally threaded tubes pass through the inner cavity of the second perforations. The two sides of the energy-absorbing sponge are respectively attached to the inner side of the energy-absorbing rubber plate and the inner wall of the side beam reinforcement.

[0011] Compared with the prior art, the advantages of this utility model are: (1) In this utility model, when a car collides, the colliding object first contacts the energy-absorbing rubber plate, and the collision force is transmitted to the energy-absorbing rubber block by the energy-absorbing rubber plate, the internal threaded tube and the extrusion plate.

In addition, the energy-absorbing rubber plate extrudes the energy-absorbing sponge on the inner side of the side beam reinforcement, and the energy-absorbing sponge absorbs the collision force of the energy-absorbing rubber plate by deformation, thereby reducing the kinetic energy of the impact.

[0012] (2) In this utility model, when the cabin side beam body is subjected to the impact force of the collision object and the energy-absorbing rubber plate, when the impact force on the cabin side beam body is too large, the connecting lug of the reinforcing member at the front of the cabin side beam body and the connecting lug of the side beam at the front of the side beam reinforcing member are separated, so as to achieve the function of absorbing and dissipating energy again, avoiding the collision force from being directly transmitted to the passenger compartment and causing injury to the passengers, thus protecting the safety of the passengers.

[0025] In this embodiment, the inner cavity of the cabin side beam body 1 is supported by the reinforcing support plate 17, and the strength of the cabin side beam body 1 is enhanced by the reinforcing rib 18.

[0026] Specifically, please refer to Figures 2 and 3. The outer side of the cabin side beam body 1 is provided with multiple tension threaded holes 19, and the energy-absorbing rubber block 4 is provided with multiple first stepped holes 20.

[0031] Working principle: In use, firstly, insert the energy-absorbing rubber block 4 into the inner side of the naval side beam body 1. Install the energy-absorbing rubber block 4 into the inner side of the naval side beam body 1 through the cooperation of the first stepped hole 20, the first bolt 21, and the tension thread hole 19.

Then, fit the side beam reinforcement 2 into the inner cavity of the naval side beam body 1, so that the front reinforcement connecting lug 11 of the naval side beam body 1 and the front side beam connecting lug 10 of the side beam reinforcement 2 are connected. The side beam reinforcement 2 is welded together to support the inner cavity of the side beam body 1, ensuring the strength of the side beam body 1. Then, when a car collision occurs, the impact object first contacts the energy-absorbing rubber plate 7. The energy-absorbing rubber plate 7, the internal threaded tube 6, and the extrusion plate 5 transmit the impact force to the energy-absorbing rubber block 4. The deformation of the energy-absorbing rubber block 4 and the energy-absorbing rubber plate 7 absorbs the impact force.

The deformation of the energy-absorbing sponge 8 absorbs the impact force of the energy-absorbing rubber plate 7, thereby reducing the kinetic energy of the impact. Finally, the side beam body 1 provides final support for the impact force on the energy-absorbing rubber block 4. When the force on the side beam body 1 is too large, the front reinforcement connecting ear 11 of the side beam body 1 and the front side beam connecting ear 10 of the side beam reinforcement 2 separate to achieve the function of absorbing and dissipating energy again.
