Technical Field

[0001] The present invention relates to the field of vehicle doors, and in particular to an adjustable vehicle door anti-collision tube beam assembly and a vehicle. Background Art

[0002] The traditional anti-collision tube beam assembly of automobile doors generally includes an anti-collision tube beam, a front connecting plate, and a rear connecting plate; the two ends of the anti-collision tube beam are respectively connected by two-way welding through the front connecting plate and the rear connecting plate to form an anti-collision tube beam assembly structure; the two ends of the anti-collision tube beam assembly structure are respectively connected to the door inner panel by spot welding through the front connecting plate and the rear connecting plate, and connected to the door outer panel by seismic isolation glue; this traditional anti-collision tube beam assembly structure will have the following problems:

[0003] 1. The anti-collision tube beam is a straight round tube, and the surface of the door outer panel has styling features, which makes the gap between the anti-collision tube beam assembly and the door outer panel in many areas too large, and the connection function of the seismic isolation glue cannot be realized, resulting in many areas of the door outer panel without support, and the overall anti-dent performance and anti-deformation ability are reduced, affecting the anti-collision performance of the door assembly;

[0004] 2. Many areas of the door outer panel cannot be supported. When customers press the door outer panel, it will deform or even make abnormal noises, which seriously reduces the customer's experience of use;

[0005] 3. To provide support for the door outer panel and match the outer panel shape, an outer panel support plate is added. The front and rear doors need to add outer panel support plates with different structures, which increases the weight and cost, and it is impossible to achieve universal support plates for the entire vehicle; Summary of the invention

[0006] In view of the defects in the prior art, the purpose of the present invention is to provide an adjustable vehicle door anti-collision tube beam assembly and a vehicle, which can effectively improve the dent resistance and external force deformation resistance of the vehicle door outer panel compared to the traditional vehicle door anti-collision tube beam assembly, thereby improving the anti-collision performance of the vehicle door, and at the same time can match door outer panels of different shapes, realize the standardization of parts, reduce parts costs, and optimize the weight of the entire vehicle.

[0010] The outer panel support plate includes an outer panel support plate groove, an outer panel support plate positioning hole and an outer panel support plate vertical flange, wherein the outer panel support plate groove is used to place seismic isolation glue and is bonded to the vehicle door outer panel through the seismic isolation glue; the outer panel support plate vertical flange is welded to the anti-collision tube beam body; the outer panel support plate positioning hole is used to cooperate with a positioning tooling fixture, and the positioning tooling fixture clamps the outer panel support plate so that the outer panel support plate vertical flange can be adjusted up and down or rotated relative to the anti-collision tube beam body.

[0011] In this technical solution, the seismic isolation glue is placed in the groove of the outer panel support plate and bonded to the door outer panel to form a support point, which plays a role in supporting the door outer panel, enhancing the supporting shock absorption effect, and further increasing the anti-dent performance of the door outer panel.

[0049] First Embodiment

[0050] like Figure 1As shown, this embodiment provides an adjustable door anti-collision tube beam assembly 2, including a front connecting plate 3, an outer plate support plate 4, an anti-collision tube beam body 5, and a rear connecting plate 6; wherein the front connecting plate 3 and the rear connecting plate 6 are connected to the front and rear ends of the anti-collision tube beam body 5 by two weldings 2A, and can also be connected to the anti-collision tube beam body 5 in an integrated manner. The middle of the anti-collision tube beam body 5 is connected to one or two spaced outer plate support plates 4 by two weldings 2A, thereby forming an adjustable door anti-collision tube beam assembly 2; one side of the anti-collision tube beam body 5 is spot-welded to the door inner panel by the front connecting plate 3 and the rear connecting plate 6, and the other side is bonded to the door outer panel 1 by the seismic isolation glue 7 on the outer plate support plate 4, thereby supporting the door outer panel 1.

[0051] like Figure 2 and Figure 3 As shown, each outer panel support plate 4 includes an outer panel support plate groove 4A, an outer panel support plate positioning hole and an outer panel support plate vertical flange 4D, wherein the seismic isolation glue 7 is clamped in the groove 4A of the outer panel support plate and bonded to the door outer panel 1 to form a support point, which plays a role in supporting the door outer panel 1, enhancing the supporting shock absorption effect, and further increasing the anti-dent performance of the door outer panel 1; the outer panel support plate vertical flange 4D is welded to the anti-collision tube beam body 5 by two protection welds 2A. The outer panel support plate positioning hole is used to cooperate with the positioning fixture 8, so that the positioning fixture 8 clamps the outer panel support plate 4 so that it can be adjusted up and down or rotated relative to the anti-collision tube beam body 5. The outer panel support plate 4 includes at least one outer panel support plate positioning hole, such as Figure 3 As shown, the outer plate support plate 4 includes an outer plate support plate secondary positioning hole 4B and an outer plate support plate main positioning hole 4C.

[0052] The adjustable principle is as follows: because the anti-collision tube beam body 5 is a straight tube beam, the door outer panel 1 has a shape feature. Before the second welding 2A is performed between the outer panel support plate 4 and the anti-collision tube beam body 5, the outer panel support plate 4 must be clamped by the positioning fixture 8, so that it can be adjusted up and down or rotated along the direction of the outer panel support plate vertical flange 4D, and the positioning height of the outer panel support plate 4 is adjusted, so as to ensure that the outer panel support plate 4 and the door outer panel 1 are bonded by the seismic isolation glue 7, and finally the door outer panel 1 with different shapes can be matched. Specifically, as Figure 4 , Figure 5As shown, the positioning fixture 8 includes a fixture adjustment end 8A, a fixture base 8E and an adjustment gasket 8D. The fixture adjustment end 8A and the fixture base 8E are connected by the adjustment gasket 8D, and the fixture adjustment end 8A is height-adjusted by the adjustment gasket 8D. The fixture adjustment end 8A is provided with a main positioning pin 8C and a secondary positioning pin 8B. The main positioning hole 4C and the secondary positioning hole 4B of the outer panel support plate are accurately positioned and fixed by the main positioning pin 8C and the secondary positioning pin 8B respectively. By adjusting the gasket 8D, the height adjustment of the positioning fixture adjustment end 8A is achieved, and the height adjustment of the outer panel support plate 4 fixed on the main positioning pin 8C and the secondary positioning pin 8B is achieved, thereby ensuring that the outer panel support plate 4 is bonded to the vehicle door outer panel 1 through the seismic isolation glue 7, and finally the vehicle door outer panel 1 of different shapes can be matched.

[0053] like Figure 3 The schematic diagram of the welding assembly of the adjustable outer panel support plate 4 and the anti-collision tube beam body 5 is shown. The door tube beam assembly can be equipped with one or more outer panel support plates 4. Each outer panel support plate 4 can be positioned up and down or rotated relative to the door outer panel 1 under the clamping of the clamp to meet the anti-dent requirements of door outer panels 1 of different shapes.

[0054] The adjustable door anti-collision tube beam assembly provided in the present embodiment increases multiple door outer panel support points by assembling two or more adjustable outer panel support plates 4 on the door tube beam assembly, thereby meeting the dent resistance requirements of door outer panels of different shapes (by increasing the support points, the dent resistance of the door outer panel of a certain vehicle model is improved by about 16.2%), while improving the safety performance of the door; in addition, the outer panel support plate 4 can be made universal (the whole vehicle saves at least 3 sets of outer panel support plate molds and inspection fixtures, totaling about 200,000 yuan); and the types of parts products are reduced, thereby reducing the cost of parts (the types of vehicle parts products are reduced from 4 to 1, saving about 2 yuan in costs).
