Description

Technical Field

[0001] This utility model relates to the field of automotive anti-collision beam technology, and in particular to an automotive aluminum alloy anti-collision beam with a surface that is corrosion-resistant and wear-resistant. Background Technology

[0002] The aluminum alloy anti-collision beam of a car is mainly a structure set between the bumper and the body to absorb large impacts. In order to ensure that the anti-collision beam maintains a certain strength after being installed in the body for a long time, it is coated with anti-rust and wear-resistant paint to ensure that the metal material properties of the anti-collision beam do not change.

[0003] However, in actual use, since the anti-collision beam is directly exposed at the bottom of the vehicle, the sand and water kicked up by the wheels during long-term driving, as well as the influence of the weather, will directly damage the paint layer on the surface of the bumper. In particular, after the sand and gravel hit the anti-collision beam and caused pinholes in the surface paint layer, water will corrode the anti-collision beam through the pinholes, forming honeycomb-like rust spots on the surface of the anti-collision beam. This directly weakens the structural strength of the anti-collision beam, and it cannot play a good role in buffering and absorbing energy in emergency situations. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide an automotive aluminum alloy anti-collision beam with a corrosion-resistant and wear-resistant surface, thereby solving the problem that the paint on the surface of the anti-collision beam is prone to pinholes during actual driving, leading to erosion of the anti-collision beam structure.

[0005] The technical solution of this utility model is: a car aluminum alloy anti-collision beam with surface anti-corrosion and wear resistance, including a main beam. The surface of the main beam is provided with a spindle-shaped groove. Several reinforcing plates are evenly spaced inside the main beam. The upper and lower sides of the inner wall of the spindle-shaped groove are provided with through grooves that communicate with the inside of the main beam. The spindle-shaped groove is connected to a main baffle through the through groove. A secondary baffle is provided on both the upper and lower sides of the main baffle.

[0006] The main beam is covered with soft rubber caps at both ends. The inner wall of the soft rubber caps is provided with protrusions that adapt to the gap between the main beam and the reinforcing plate. The surface of the protrusions is provided with a locking block corresponding to the reinforcing plate, and the surface of the reinforcing plate is provided with a locking groove corresponding to the locking block.

[0007] Furthermore, there are three reinforcing plates. One of them is horizontally positioned at the center of the main beam, connecting the inner wall of the main beam to the spindle-shaped groove. The other two reinforcing plates are symmetrically positioned on both sides of the horizontal reinforcing plate in an inclined state, which strengthens the lateral support inside the main beam and prevents the main beam from losing strength due to the spindle-shaped groove.

[0008] Furthermore, the main baffle is composed of a connecting part and an extension part. The connecting part is adapted to the internal shape of the shuttle-shaped groove and has protrusions on its surface that engage with the through groove. The extension part is located on both sides of the connecting part and extends upward and downward to cover the impact surface of the main beam, so that the main baffle can be connected to the main beam without additional fixing and ensures reliable connection strength.

[0009] Furthermore, both the secondary baffle and the main baffle are made of plastic. The secondary baffle has a lower hardness and greater toughness than the main baffle. The different properties of the plastic materials can be adapted to different coverage areas of the main baffle and the secondary baffle to optimize the usage effect.

[0010] Furthermore, the secondary baffles extend towards one side of the main beam along the connection with the main baffle, wherein the length of the secondary baffle located at the top of the main beam is shorter than that of the secondary baffle located at the bottom, and the connection between the secondary baffle and the main baffle is thickened and reinforced to ensure that no gap is generated between the secondary baffle and the main beam during use.

[0011] Furthermore, the hardness of the protrusion is greater than that of the soft rubber cover, and the soft rubber cover is distributed in a skirt-like shape on the edge of the protrusion to ensure that the soft rubber cover as a whole has sufficient structural support.

[0012] Furthermore, the soft rubber cover extends to cover both ends of the main beam and both ends of the main baffle and the secondary baffle, thereby optimizing the coverage effect of the main baffle and the secondary baffle on the main beam by covering the gaps between the main baffle and the secondary baffle and between the main beam.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model covers the impact surface and upper and lower sides of the main beam with a main baffle and a secondary baffle, preventing sand and sewage kicked up by the wheels from contacting the main beam. At the same time, the main baffle and the secondary baffle are independent of the main beam and can be replaced by the driver according to the actual situation after a certain period of driving. The soft rubber cover on both sides of the main beam can seal the cavity inside the main beam from the outside, preventing external pollution from contacting the unpainted part inside the main beam, thus strengthening the protection of the main beam and extending the service life of the anti-collision beam.

[0015] 2. This utility model also separates the deformation area of ​​the main beam by setting grooves on the surface of the main beam to place the main baffle and the secondary baffle. At the same time, a reinforcing plate is set at a specific position inside the main beam to prevent the main beam from reducing the overall strength due to the grooves. This allows the main beam to connect the main baffle and the secondary baffle without additional components while ensuring structural strength. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] like Figure 1-6 As shown, an aluminum alloy anti-collision beam for automobiles with a surface that is corrosion-resistant and wear-resistant includes a main beam 1. The surface of the main beam 1 is provided with a spindle-shaped groove 2. A number of reinforcing plates 3 are evenly spaced inside the main beam 1. There are three reinforcing plates 3 in total. One of them is horizontally set at the center of the main beam 1 and connects the inner wall of the main beam 1 with the spindle-shaped groove 2. The other two reinforcing plates 3 are symmetrically set on both sides of the horizontal reinforcing plate 3 in an inclined state to enhance the lateral support force inside the main beam 1 and prevent the main beam 1 from losing strength due to the spindle-shaped groove 2.

[0025] The inner wall of the spindle-shaped groove 2 has through slots 4 on both the upper and lower sides, which communicate with the interior of the main beam 1. The spindle-shaped groove 2 is engaged with a main baffle 5 through the through slots 4. The main baffle 5 consists of a connecting part and an extending part. The connecting part is adapted to the internal shape of the spindle-shaped groove 2 and has protrusions on its surface that engage with the through slots 4. The extending part is located on both sides of the connecting part and extends upward and downward to cover the impact surface of the main beam 1, so that the main baffle 5 can be connected to the main beam 1 without additional fixing and ensures reliable connection strength. Auxiliary baffles 6 are provided on both the upper and lower sides of the main baffle 5. Both the baffle 6 and the main baffle 5 are made of plastic. The material of the secondary baffle 6 is less hard than that of the main baffle 5 but more tough. The different properties of the plastic materials can be adapted to the different coverage areas of the main baffle 5 and the secondary baffle 6 to optimize the use effect. The secondary baffle 6 extends towards the main beam 1 along the connection with the main baffle 5. The length of the secondary baffle 6 at the top of the main beam 1 is shorter than that at the bottom. The connection between the secondary baffle 6 and the main baffle 5 is thickened and reinforced to ensure that there is no gap between the secondary baffle 6 and the main beam 1 during use.

[0026] The main beam 1 is covered with soft rubber caps 101 at both ends. The soft rubber caps 101 cover both ends of the main beam 1 and extend to cover both ends of the main baffle 5 and the secondary baffle 6. By covering the gaps between the main baffle 5 and the secondary baffle 6 and between the soft rubber caps 101 and the main beam 1, the coverage effect of the main baffle 5 and the secondary baffle 6 on the main beam 1 is optimized. The inner wall of the soft rubber cap 101 is provided with protrusions 102 that adapt to the gap between the main beam 1 and the reinforcing plate 3. The hardness of the protrusions 102 is greater than that of the soft rubber cap 101. The soft rubber caps 101 are distributed in a skirt shape on the edge of the protrusions 102 to ensure that the soft rubber cap 101 as a whole has sufficient structural support. The surface of the protrusions 102 is provided with a locking block 103 corresponding to the reinforcing plate 3, and the surface of the reinforcing plate 3 is provided with a locking groove 104 corresponding to the locking block 103.

[0027] Working principle of this utility model:

[0028] Firstly, during use, the operator can push the main baffle 5 along the side end of the spindle groove 2 or directly along the front of the spindle groove 2, depending on the actual situation. After deformation, the main baffle 5 is engaged with the main beam 1 through the through groove 4. At this time, the main baffle 5 covers the front of the main beam 1, and the auxiliary baffle 6 covers the upper and lower sides of the main beam 1. Then, the operator uses the soft rubber cover 101 to seal both ends of the main beam 1. During the installation process, ensure that the protrusion 102 is adapted to the inner reinforcing plate 3 of the main beam 1 and is pushed in. During the pushing process, the locking block 103 on the surface of the protrusion 102 engages with the locking groove 104 on the surface of the reinforcing plate 3 to complete the installation of the soft rubber cover 101.

[0029] In actual use, the sand and wastewater kicked up by the vehicle wheels will first and mainly come into contact with the main baffle 5 and the sub-baffle 6 at the bottom of the main baffle 5. The main baffle 5 and the sub-baffle 6 prevent debris from directly contacting the main beam 1. At the same time, water vapor and impurities in the air cannot directly contact the unpainted part inside the main beam 1 through the soft rubber cover 101, thus optimizing the protection effect on the main beam 1.

[0030] When the main baffle 5 and the auxiliary baffle 6 wear out after a period of use, they can be pulled out directly for maintenance or replacement. The replacement process is the same as above, and no other auxiliary tools are needed during the replacement process. The operation is simple and quick.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
