Description

Technical Field

[0001] This utility model relates to the field of automotive parts, and in particular to a high-strength automotive rear suspension crossbeam connecting plate. Background Technology

[0002] The rear suspension crossbeam connecting plate is an important component of the rear suspension system. It is a component that connects the rear suspension crossbeam to other parts of the vehicle body. It is usually located at the rear of the vehicle and serves to support and fix the suspension system.

[0003] However, existing technologies lack effective central weight reduction and central strength support, as well as edge protection for connecting plates. In use, these existing connecting plates are mostly integral, which are not only prone to bending and increasing vehicle weight, but also cause significant damage and economic losses in the event of a hard impact on the bottom of the vehicle during a collision.

[0004] In view of this, this paper studies and improves upon existing problems, providing a high-strength automotive rear suspension crossbeam connecting plate. In use, it can not only reduce the overall weight of the connecting plate and increase its overall strength, but also change the angle of force transmission when the vehicle is bumped at the bottom, thus reducing damage to the vehicle. The aim of this technology is to solve the problem and improve its practical value. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-strength automotive rear suspension crossbeam connecting plate. By modifying the internal structure of the connecting plate and adding a flexible contact surface to its exterior, this invention not only reduces the overall weight of the connecting plate and increases its overall strength during use, but also changes the angle of force transmission when the vehicle is bumped at the bottom, thus reducing damage to the vehicle.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: It includes a hollow, side-arc-shaped crossbeam connecting plate. A right-side mounting plate is integrally formed on one side of the hollow, side-arc-shaped crossbeam connecting plate, and a left-side mounting plate is integrally formed on the other side. Reinforcing side plates are welded to both the upper ends of the right-side and left-side mounting plates. Alignment mounting holes are provided in the middle of both the right-side and left-side mounting plates. A left-side limiting sliding rail and a right-side limiting sliding rail are integrally formed in the middle of the four sides of the hollow, side-arc-shaped crossbeam connecting plate. The right-side limiting sliding rail is located on one side of the left-side limiting sliding rail. A triangular support core is integrally formed in the middle of the hollow, side-arc-shaped crossbeam connecting plate. A rubber protective sleeve is movably connected to the outer surface of the hollow, side-arc-shaped crossbeam connecting plate. An anti-slip rubber shell is bonded to the outer surface of the rubber protective sleeve. An internal rotating groove is provided in the middle of the rubber protective sleeve.

[0007] Preferably, the inner perimeter of the rubber protective sleeve is movably connected to the outer surfaces of the left and right limiting sliding rails via an internal rotating groove.

[0008] Preferably, one side of the right mounting plate is movably connected to one side of the rubber protective sleeve, and one side of the left mounting plate is movably connected to the other side of the rubber protective sleeve.

[0009] Preferably, the right mounting plate and the left mounting plate have the same structure, and the hollow side arc-shaped crossbeam connecting plate, the rubber protective sleeve and the anti-slip rubber sleeve shell have the same length.

[0010] Preferably, the shape of the internal rotating slot is the same as the shape of the left limiting slide rail and the right limiting slide rail.

[0011] Preferably, the interior of the triangular support core is a triangular support block, and the interior of the triangular support core forms six sets of triangular support spaces.

[0012] Preferably, the rubber protective sleeve and the anti-slip rubber shell are made of polyurethane elastomer.

[0013] This utility model has the following beneficial effects:

[0014] In this utility model, a high-strength automotive rear suspension crossbeam connecting plate is installed by connecting bolts passing through the alignment holes in the middle of the right and left mounting plates to complete the installation of the hollow side arc-shaped crossbeam connecting plate. The right and left mounting plates are reinforced by side plates to provide lateral support to the hollow side arc-shaped crossbeam connecting plate. When the bottom of the vehicle is bumped after installation, the anti-slip rubber sleeve on the rubber protective cover first contacts the object. The rubber protective cover at the bottom of the anti-slip rubber sleeve slides on the left and right limiting sliding rails on the hollow side arc-shaped crossbeam connecting plate, changing the direction of the collision transmission. In use, this not only reduces the overall weight of the connecting plate and increases its overall strength, but also changes the angle of collision force transmission when the bottom of the vehicle is bumped, reducing damage to the vehicle.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figure 1-4A high-strength automotive rear suspension crossbeam connecting plate includes a hollow side-arc crossbeam connecting plate 1. A right-side mounting plate 2 is integrally formed on one side of the hollow side-arc crossbeam connecting plate 1, and a left-side mounting plate 3 is integrally formed on the other side. Reinforcing side plates 4 are welded to both the upper ends of the right-side mounting plate 2 and the left-side mounting plate 3. Alignment mounting holes 5 are formed in the middle of both the right-side mounting plate 2 and the left-side mounting plate 3. A left-side limiting sliding rail 6 and a right-side limiting sliding rail 7 are integrally formed in the middle of the hollow side-arc crossbeam connecting plate 1, with the right-side limiting sliding rail 7 located on one side of the left-side limiting sliding rail 6. A triangular support core 8 is integrally formed in the middle of the hollow side-arc crossbeam connecting plate 1. A rubber protective sleeve 9 is movably connected to the outer surface of the hollow side-arc crossbeam connecting plate 1. An anti-slip rubber sleeve shell 10 is bonded to the outer surface of the rubber protective sleeve 9. A [missing information - likely a design feature] is formed in the middle of the rubber protective sleeve 9. The internal rotating slot 11 allows for the installation of the hollow side arc-shaped crossbeam connecting plate 1 by passing the connecting bolts through the alignment mounting holes 5 in the middle of the right mounting plate 2 and the left mounting plate 3 during the installation of the connecting plate. The right mounting plate 2 and the left mounting plate 3 are supported laterally by the reinforcing side plate 4. When the bottom of the vehicle is bumped after installation, the anti-slip rubber sleeve 10 on the rubber protective sleeve 9 will first come into contact with the object. The rubber protective sleeve 9 at the bottom of the anti-slip rubber sleeve 10 will slide and be limited by the left limiting sliding rail 6 and the right limiting sliding rail 7 on the hollow side arc-shaped crossbeam connecting plate 1, changing the direction of the collision transmission. In use, this not only reduces the overall weight of the connecting plate and increases its overall strength, but also changes the angle of the collision force transmission when the bottom of the vehicle is bumped, reducing damage to the vehicle.

[0023] Specifically, the rubber protective sleeve 9 is movably connected to the outer surfaces of the left and right limiting sliding rails 6 and 7 through the internal rotating groove 11. The rubber protective sleeve 9 contacts the left and right limiting sliding rails 6 and 7 through the internal rotating groove 11 to complete the limiting sliding work of the rubber protective sleeve 9.

[0024] Specifically, one side of the right mounting plate 2 is movably connected to one side of the rubber protective sleeve 9, and one side of the left mounting plate 3 is movably connected to the other side of the rubber protective sleeve 9. The right mounting plate 2 and the left mounting plate 3 are used to restrict the two sides of the rubber protective sleeve 9.

[0025] Specifically, the right mounting plate 2 and the left mounting plate 3 have the same structure. The hollow side arc-shaped crossbeam connecting plate 1, the rubber protective sleeve 9 and the anti-slip rubber sleeve 10 have the same length. The same length and structure can ensure the weight level of the connecting plate and avoid the center of gravity deviation.

[0026] Specifically, the shape of the internal rotating slot 11 is the same as the shape of the left limiting slide rail 6 and the right limiting slide rail 7, so that the shape of the internal rotating slot 11 and the left limiting slide rail 6 and the right limiting slide rail 7 can be engaged to ensure the stability of the movement.

[0027] Specifically, the interior of the triangular support core 8 is a triangular support block, forming six sets of triangular support spaces inside the triangular support core 8, which reduces the weight of the connecting plate and improves the structural strength.

[0028] Specifically, the rubber protective sleeve 9 and the anti-slip rubber shell 10 are made of polyurethane elastomer, which has good wear resistance as well as excellent mechanical strength, oil resistance and flexural strength.

[0029] Working principle: During the installation of the connecting plate, the hollow side arc-shaped crossbeam connecting plate 1 is installed by passing the connecting bolts through the alignment mounting holes 5 in the middle of the right mounting plate 2 and the left mounting plate 3. The right mounting plate 2 and the left mounting plate 3 are supported laterally by the reinforcing side plate 4. When the bottom of the vehicle is bumped after installation, the anti-slip rubber sleeve 10 on the rubber protective sleeve 9 first contacts the object. The rubber protective sleeve 9 at the bottom of the anti-slip rubber sleeve 10 is limited and slid by the left limiting sliding rail 6 and the right limiting sliding rail 7 on the hollow side arc-shaped crossbeam connecting plate 1, changing the direction of the collision transmission. In use, this not only reduces the overall weight of the connecting plate and increases its overall strength, but also changes the angle of the collision force transmission when the bottom of the vehicle is bumped, reducing damage to the vehicle.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
