Description

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] Traditional automobile door anti-collision tube beam assemblies generally include 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 spot-welded to the door inner panel through the front connecting plate and the rear connecting plate, and connected to the door outer panel with seismic isolation glue. This traditional anti-collision tube beam assembly structure has the following problems:

[0003] 1. The anti-collision beam is a straight circular tube. The door outer panel has surface features that create large gaps between the anti-collision beam assembly and the door outer panel. This prevents the seismic isolation rubber from providing a connection. This leaves many areas of the door outer panel unsupported, reducing overall dent and deformation resistance, and impacting the door assembly's anti-collision performance.

[0004] 2. Many areas of the door outer panel cannot support the vehicle. When customers press on the door outer panel, it will cause deformation or even abnormal noise, which seriously reduces the customer's experience of use.

[0005] 3. To provide support for the door outer panels and match the outer panel shape, additional outer panel support plates are required. These outer panel support plates have different structures for the front and rear doors, increasing weight and cost, and preventing the support plates from being universal across the vehicle. Summary of the Invention

[0006] In response to 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. Compared with traditional automobile door anti-collision tube beam assemblies, the vehicle door outer panel's anti-dent performance and resistance to external force deformation can be effectively improved, thereby improving the vehicle door's anti-collision performance. At the same time, it can match vehicle door outer panels of different shapes, realize the standardization of parts, reduce parts costs, and optimize the weight of the entire vehicle.

[0007] In order to achieve the above technical effects, the present invention adopts the following technical solutions:

[0008] According to a first aspect of the present invention, there is provided an adjustable vehicle door anti-collision tube beam assembly, comprising a front connecting plate, an outer panel support plate, an anti-collision tube beam body, and a rear connecting plate;

[0009] The front connecting plate and the rear connecting plate are respectively connected to the two ends of the anti-collision tube beam body, and the anti-collision tube beam body is connected to one or more spaced outer plate support plates by two-way welding; one side of the anti-collision tube beam body is spot-welded to the vehicle door inner panel by the front connecting plate and the rear connecting plate, and the other side is bonded to the vehicle door outer panel by the seismic isolation glue on the outer plate support plate;

[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 the 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 the positioning fixture, and the positioning 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 adhesive is placed in the groove of the outer panel support plate and bonded to the door outer panel, forming a support point. This supports the door outer panel, enhances the support and shock absorption effect, and further improves the door outer panel's dent resistance. Furthermore, by adjusting the positioning height of the outer panel support plate, it can be matched to different door outer panel shapes to meet the dent resistance requirements of different door outer panel shapes.

[0012] Optionally, the front connecting plate and the rear connecting plate are connected to both ends of the anti-collision tube beam body by double welding.

[0013] Optionally, the front connecting plate and the rear connecting plate are integrally connected to both ends of the anti-collision tube beam body.

[0014] Optionally, the vertical flange of the outer plate support plate is connected to the anti-collision tube beam body by double welding.

[0015] Optionally, the outer plate support plate includes at least one outer plate support plate positioning hole.

[0016] Optionally, the positioning fixture is provided with a positioning pin, which can cooperate with the positioning hole of the outer panel support plate to position and fix the outer panel support plate on the positioning fixture, so that the outer panel support plate can be adjusted up and down or rotated along with the positioning fixture.

[0017] According to a second aspect of the present invention, a vehicle is provided, comprising the above-mentioned adjustable door anti-collision tube beam assembly.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The adjustable door anti-collision tube beam assembly provided by the present invention can be equipped with one or more outer panel support plates. On the one hand, multiple door outer panel support points are added. On the other hand, due to the adjustable positioning of the outer panel support plates, the safety performance of the door can be improved while meeting the dent resistance requirements of door outer panels of different shapes.

[0020] 2. The adjustable door anti-collision tube beam assembly provided by the present invention can match door outer panels of different shapes through an adjustable structure composed of one or more adjustable outer panel support plates, thereby realizing the universalization of outer panel support plates, reducing parts costs, and optimizing the weight of the entire vehicle.

[0049] First embodiment

[0050] like Figure 1As shown, this embodiment provides an adjustable vehicle door anti-collision tube beam assembly 2, comprising 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 vehicle door anti-collision tube beam assembly 2; one side of the anti-collision tube beam body 5 is spot-welded to the vehicle door inner panel by the front connecting plate 3 and the rear connecting plate 6, and the other side is bonded to the vehicle door outer panel 1 by the seismic isolation glue 7 on the outer plate support plate 4, thereby supporting the vehicle 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 vehicle door outer panel 1 to form a support point, which plays the role of supporting the vehicle door outer panel 1, enhancing the supporting shock absorption effect, and further increasing the anti-dent performance of the vehicle door outer panel 1; the outer panel support plate vertical flange 4D is welded to the anti-collision tube beam body 5 by two weldings 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 auxiliary 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 car door outer panel 1 has a styling feature. Before performing the second welding 2A 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. The positioning height of the outer panel support plate 4 is adjusted to ensure that the outer panel support plate 4 and the car door outer panel 1 are bonded by the seismic isolation glue 7, and finally the car 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 can be 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 precisely positioned and fixed by the main positioning pin 8C and the secondary positioning pin 8B respectively. The height of the positioning fixture adjustment end 8A is adjusted by adjusting the gasket 8D, and the height of the outer panel support plate 4 fixed on the main positioning pin 8C and the secondary positioning pin 8B is adjusted, thereby ensuring that the outer panel support plate 4 and the vehicle door outer panel 1 are bonded by the seismic isolation glue 7, and ultimately can match vehicle door outer panels 1 of different shapes.

[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 with different shapes.

[0054] The adjustable door anti-collision tube beam assembly provided in this 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, which can meet 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 model is improved by about 16.2%), while improving the safety performance of the door; in addition, it can also realize the universalization of the outer panel support plate 4 (saving at least 3 sets of molds and inspection fixtures for the outer panel support plate of the whole vehicle, totaling about 200,000 yuan); and reduce the variety of parts products and reduce the cost of parts (the variety of parts products for the whole vehicle is reduced from 4 to 1, saving about 2 yuan in costs).
