Description

Technical Field

[0001] The present application relates to the technical field of vehicle parts, and more specifically, to a vehicle body painting bracket, a vehicle body painting structure assembly and a vehicle. Background Art

[0002] Currently, the front painting lifting points of the vehicle body are usually realized by directly drilling holes in the front longitudinal beam, door sill beam connecting plate and other front vehicle body structures. The existing direct drilling method will destroy the integrity of the vehicle body structure and affect the strength of the vehicle body structure. Especially when the holes used for painting and assembly processes cannot be shared and multiple holes are required in this area, it will significantly affect the force transmission effect of the front vehicle body structure and reduce the collision safety performance. In addition, the method of directly drilling holes in the front vehicle body structure such as the door sill beam connecting plate for lifting relies on the large surface of the connecting plate to support the hanging, and the support force transmission efficiency is not high. In order to improve the force transmission effect of the vehicle body structure that has been drilled, it is necessary to increase the material thickness or add reinforcement plates, but this method will make the vehicle body structure bulky and costly.

[0059] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0060] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may also be a centered element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may also be a centered element. When an element is considered to be "set on" another element, it may be directly set on the other element or there may also be a centered element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0061] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present application. The terms used herein in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0062] Some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.

[0063] From design to production, automobiles need to go through four major processes: stamping, welding, painting, and assembly. In order to facilitate production, various process holes need to be designed and reserved on parts and bodies. For example, the body painting lifting point requires a hoist to lift the body through the painting lifting point and put it into the electrothermal tank in the painting process line. The popularization of smart factories and smart production equipment and the improvement of flexible production requirements have put higher and higher requirements on process holes.

[0064] Currently, the front painting lifting points of the vehicle body are usually realized by directly drilling holes in the front longitudinal beam, door sill beam connecting plate and other front vehicle body structures. The existing direct drilling method will destroy the integrity of the vehicle body structure and affect the strength of the vehicle body structure. Especially when the holes used for painting and assembly processes cannot be shared and multiple holes are required in this area, it will significantly affect the force transmission effect of the front vehicle body structure and reduce the collision safety performance. In addition, the method of directly drilling holes in the front vehicle body structure such as the door sill beam connecting plate for lifting relies on the large surface of the connecting plate to support the hanging, and the support efficiency is not high. In order to improve the force transmission effect of the vehicle body structure that has been drilled, it is necessary to increase the material thickness or add reinforcement plates, but this method will make the vehicle body structure bulky and costly.

[0065] The present application provides a vehicle body painting bracket, a vehicle body painting structure assembly and a vehicle, wherein the vehicle body painting bracket includes a support panel and a support portion. The support panel includes an integrally formed first part and a second part, and the first part and the second part form a partially enclosed structure with a notch, so that the support panel roughly forms a triangular structure, which is conducive to improving the support effect of the bracket. At least one through hole is provided on the first part and / or the second part, which is used as a vehicle body painting hanging point. The support portion is connected to the side of the first part and the second part, and the support portion extends along the vehicle body height direction. The support panel and the support portion of the vehicle body painting bracket can be respectively configured to connect the longitudinal beam structure, the sill beam structure and the connecting plate in the front structure of the vehicle body, so as to add a painting hanging point without destroying the front structure of the vehicle body, avoid affecting the force transmission effect of the front structure of the vehicle body, and can ensure the force transmission efficiency in the length direction of the vehicle body while improving the force transmission efficiency in the height direction of the vehicle body. The triangular support structure formed by the first part and the second part can also form a stable support in the connecting structure of the longitudinal beam structure, the sill beam structure and the connecting plate, thereby improving the strength and rigidity of the front structure of the vehicle body.

[0066] Those skilled in the art can understand that the "body painting structure assembly" is a part of the vehicle body structure and is a structure for hoisting during the painting process. The body painting structure assembly of the present application includes a longitudinal beam structure, a threshold beam structure, a connecting plate and the above-mentioned body painting bracket. The longitudinal beam structure, the threshold beam structure and the connecting plate are connected by the body painting bracket, and the hoisting point is set on the body painting bracket to avoid opening holes in the main body structure, maintain the integrity of the body structure, and ensure the force transmission effect of the body structure.

[0067] It should be noted that, in the figure, the X direction is the length direction X of the vehicle body, the Y direction is the width direction Y of the vehicle body, and the Z direction is the height direction Z of the vehicle body. Among them, the X direction, the Y direction, and the Z direction are perpendicular to each other, and the positional relationship of each element in this coordinate system will be explained in the subsequent embodiments.

[0068] The following will describe exemplary embodiments in conjunction with the accompanying drawings. It should be noted that the components depicted in the reference drawings are not necessarily shown to scale; and the same or similar components will be given the same or similar reference numerals or similar technical terms.

[0069] See also Figure 1 and Figure 2 , this embodiment provides a vehicle body painting bracket 100, including a support panel 10 and a support portion 13. The support panel 10 includes an integrally formed first part 11 and a second part 12, and the first part 11 and the second part 12 form a partially enclosed structure with a notch 18, so that the support panel 10 roughly forms a triangular structure, which is conducive to improving the support effect of the bracket. In this embodiment, the partially enclosed structure refers to the support panel 10 being constructed as a non-enclosed structure along its circumference, and the notch 18 is formed between the two ends of the length direction of the partially enclosed structure itself. In this way, the surface of the support panel 10 is strip-shaped, and compared with the planar surface, the possibility of deformation of the support panel 10 when subjected to force is greatly reduced, thereby improving the force transmission efficiency and structural stability of the support panel 10. Among them, the first part 11 and the second part 12 can be constructed as two straight strip structures that intersect obliquely, or as two connected arc-shaped strip structures, or one of the first part 11 and the second part 12 is a straight strip structure and the other is an arc-shaped strip structure, as long as an unenclosed structure with a notch 18 is formed.

[0070] At least one through hole 17 is provided on the first part 11 and / or the second part 12, which is used as a hanging point for the vehicle body painting. The support part 13 is connected to the side of the first part 11 and the second part 12, and the support part 13 extends along the height direction Z of the vehicle body. Figure 3 and Figure 4 As shown, the support panel 10 and the support part 13 of the vehicle body painting bracket 100 can be respectively configured to connect the longitudinal beam structure 20, the sill beam structure 30 and the connecting plate 40 in the front structure of the vehicle body, so as to add a painting hanging point without destroying the front structure of the vehicle body, so as to avoid affecting the force transmission effect of the front structure of the vehicle body. The triangular support structure formed by the first part 11 and the second part 12 can also form a stable support in the connection structure of the longitudinal beam structure 20, the sill beam structure 30 and the connecting plate 40, thereby improving the strength and rigidity of the front structure of the vehicle body.

[0071] Specifically, Figure 1 and Figure 2As shown, the vehicle body painting bracket 100 can be a sheet metal structure. The support panel 10 is roughly in the plane where the vehicle body length direction X and the vehicle body width direction Y are located. The support portion 13 is arranged below the support panel 10 along the vehicle body height direction Z, and is connected to the side of the first part 11 and the second part 12. The adjacent outer edges of the first part 11 and the second part 12 intersect and form an angle less than 180°. A gap 18 is formed between the adjacent inner sides of the first part 11 and the second part 12, and the gap 18 can avoid other structures of the vehicle body during the installation of the vehicle body painting bracket 100, and adapt to a variety of complex installation situations. In an embodiment of the present application, the first part 11 and the second part 12 each have two through holes 17 as vehicle body painting hanging points. In other embodiments, the through holes 17 on the first part 11 and the second part 12 can be more or less than two, and can be set according to the hoisting requirements, and the present application is not limited to this. The plurality of through holes 17 can be used as various process holes, such as welding positioning holes, assembly transfer holes, etc., so that various process holes can be integrated on the support panel 10.

[0072] In some embodiments, Figures 1 to 4 As shown, the end of the first part 11 away from the second part 12 extends along the first direction M so that the first part 11 can be connected to the body 301 of the vehicle 300. The body painting bracket 100 also includes a first connecting portion 15, which is arranged at the end of the first part 11 away from the second part 12. In this embodiment, after the body painting bracket 100 is installed on the vehicle body 301, the first direction M is roughly parallel to the body width direction Y (that is, the first direction M is parallel to the body width direction Y, or the angle between the two is within 10°). The first connecting portion 15 is configured to connect the sill beam structure 30 to connect the body painting bracket 100 and the sill beam structure 30 in the body width direction Y.

[0073] In some embodiments, the number of the first connection parts 15 is two, one of which is arranged on the side of the first part 11 away from the support part 13, so as to form a sheet-like structure that folds upward at the free end of the first part 11. After the vehicle body painting bracket 100 is installed on the vehicle body 301, the first connection part 15 is arranged on the first part 11 along the vehicle body height direction Z, so as to facilitate the connection with the surface structure of the threshold beam structure 30. Another first connection part 15 is arranged on the side of the first part 11 along the second direction N, and is connected to the support part 13 on the side of the first part 11. The first connection part 15 extends along the second direction N to form a sheet-like structure that folds toward the first direction M on the side of the free end of the first part 11. After the vehicle body painting bracket 100 is installed on the vehicle body 301, the second direction N is roughly parallel to the vehicle body length direction X (that is, the second direction N is parallel to the vehicle body length direction X, or the intersection angle between the two is within 10°). The surfaces of the two first connection parts 15 are substantially in the same plane, so as to be connected to the sill beam structure 30 in the vehicle body width direction Y, and realize the connection and positioning of the first part 11 and the sill beam structure 30. It can be understood that in other embodiments, the number of the first connection parts 15 can also be one or more than two, as long as the connection and positioning requirements of the first part 11 and the sill beam structure 30 in the vehicle body width direction Y are met, and the present application is not limited thereto.

[0074] In some embodiments, the end of the second part 12 away from the first part 11 extends along the second direction N so that the second part 12 can be connected to the vehicle body 301. The vehicle body painting bracket 100 also includes a second connecting portion 16, which is disposed at the end of the second part 12 away from the first part 11. The second connecting portion 16 is configured to connect the longitudinal beam structure 20 to connect the vehicle body painting bracket 100 and the longitudinal beam structure 20 in the vehicle body length direction X. The second connecting portion 16 is disposed on the side of the second part 12 away from the support portion 13 along the vehicle body height direction Z to form an upwardly folded sheet structure at the free end of the second part 12, which is convenient for connection with the surface structure of the longitudinal beam structure 20. In the embodiments of the present application, the number of the second connecting portion 16 is one, and in other embodiments, the number of the second connecting portion 16 can also be two or more, and the present application is not limited thereto.

[0075] In some embodiments, the vehicle body painting bracket 100 further includes a third connection portion 14, which is disposed at one end of the support portion 13 away from the support panel 10. The third connection portion 14 is substantially parallel to the support panel 10, so as to form a sheet structure at the free end of the support portion 13, increase the connection area between the support portion 13 and the connection plate 40, and facilitate welding and fixing the surfaces of the support portion 13 and the connection plate 40 along the vehicle body height direction Z.

[0076] The present application sets support parts 13 on the side edges of each part of the support panel 10 along the vehicle body height direction Z to connect with the front structure of the vehicle body. The support part 13 is designed to increase a direct force transmission path, directly transfer the load to the vehicle body, improve the load transmission efficiency, and avoid the problem of force transmission path damage caused by the opening of the front structure of the vehicle body; at the same time, a first connecting part 15 and a second connecting part 16 are respectively set in the vehicle body width direction Y and the vehicle body length direction X to connect with the longitudinal beam structure 20 and the threshold beam structure 30 respectively, thereby increasing the force transmission path of the vehicle body painting bracket 100 in the vehicle body width direction Y and the vehicle body length direction X. Combined with the force transmission path of the support part 13 in the vehicle body height direction Z, the stiffness, strength and bearing capacity of the entire vehicle body painting bracket 100 in three-dimensional space are greatly improved to meet the transportation and painting flipping requirements of the vehicle 300.

[0077] In some embodiments, there are multiple support parts 13, and the multiple support parts 13 are spaced apart and distributed on the sides of the first part 11 and the second part 12. The positions and sizes of the multiple support parts 13 can be designed according to actual installation requirements, and the connection requirements of the vehicle body painting bracket 100 and the connecting plate 40 in the vehicle body height direction Z can be met, and the present application is not limited thereto.

[0078] In other embodiments, the support portion 13 arranged on the adjacent sides of the first part 11 and the second part 12 is connected as a whole, so that the support portion 13 becomes a sheet structure surrounding the side of the support panel 10, and the entire vehicle body painting bracket 100 is roughly box-shaped, which is conducive to simplifying the manufacturing process of the vehicle body painting bracket 100.

[0079] In some embodiments, the side of the support panel 10 and / or the side around the through hole 17 are further provided with a reinforcement edge 101. Specifically, the reinforcement edge 101 can be a flange structure integrally formed with the support panel 10. The reinforcement edge 101 on the side of the support panel 10 is set in an area not connected to the support portion 13. The side around the through holes 17 of some of the multiple through holes 17 are provided with a reinforcement edge 101, which is conducive to further improving the structural strength of the vehicle body painting bracket 100. In other embodiments, the side around the through holes 17 can be provided with a reinforcement edge 101 to meet the design requirements, and the present application is not limited thereto.

[0080] See also Figures 1 to 6 The embodiment of the present application further provides a vehicle body painting structure assembly 200, comprising a longitudinal beam structure 20, a threshold beam structure 30, a connecting plate 40 and a vehicle body painting bracket 100 described in the above embodiment or a combination of embodiments. The threshold beam structure 30 connects the longitudinal beam structure 20, the connecting plate 40 is installed at the connection between the longitudinal beam structure 20 and the threshold beam structure 30, and the vehicle body painting bracket 100 connects the longitudinal beam structure 20, the threshold beam structure 30 and the connecting plate 40.

[0081] This application connects the longitudinal beam structure 20, the threshold beam structure 30 and the connecting plate 40 through the body painting bracket 100, and the lifting point is set on the body painting bracket 100, so that the painting hanging point is designed separately from the collision force transmission path, avoiding opening holes on the main body structure of the body, while achieving the painting hanging effect, maintaining the integrity of the body structure, ensuring the force transmission effect of the body structure, and maximizing the collision safety performance of the front structure of the body. In addition, the through hole 17 used as the process hole is set on the body painting bracket 100, which is flexible in design, improving production flexibility and the commonality rate of the same architecture model. When the vehicle 300 is transferred to the factory and the production line is changed, only the outline size of the body painting bracket 100 needs to be changed to meet the requirements of different production lines, and the structure is universal. At the same time, for different models of the same architecture, the same longitudinal beam structure 20, the threshold beam structure 30 and the connecting plate 40 can be used through the design of the body painting bracket 100, and the model development is realized with minimal changes to improve the commonality rate.

[0082] Furthermore, if Figures 3 to 6 As shown, the vehicle body painting bracket 100 is arranged above the connecting plate 40 along the vehicle body height direction Z, the supporting portion 13 of the vehicle body painting bracket 100 is fixedly connected to the connecting plate 40, the first portion 11 of the supporting panel 10 in the vehicle body painting bracket 100 is fixedly connected to the threshold beam structure 30, and the second portion 12 of the supporting panel 10 is fixedly connected to the longitudinal beam structure 20. The connection method is preferably welding connection, but is not limited to welding, riveting, screwing and the like. The vehicle body painting bracket 100 forms a triangular support structure at the connection between the longitudinal beam structure 20, the threshold beam structure 30 and the connecting plate 40, rigidifies the area, plays an auxiliary force transmission role, further improves safety during collision, and can protect the battery pack located on the inner side of the threshold beam. On the other hand, the triangular support structure has better stability, and the vehicle body painting bracket 100 has higher stability.

[0083] Since each component of the vehicle body painting structure assembly 200 can be designed independently, by differentiating the thickness of the components and adjusting the thickness and size of the longitudinal beam structure 20, the door sill beam structure 30, the connecting plate 40 and the vehicle body painting bracket 100 according to the stress conditions of different parts, a lightweight design of the local structure can be achieved, which is beneficial to reducing weight and cost.

[0084] In some embodiments, Figure 4 , Figure 5 and Figure 6As shown, the longitudinal beam structure 20 includes a first section 21 and a second section 22 connected to each other. The first section 21 is arranged along the length direction X of the vehicle body, and the second section 22 is inclined relative to the first section 21 and connected to the sill beam structure 30. In this way, the first section 21 and the sill beam structure 30 are staggered by a certain distance in the width direction Y of the vehicle body to meet other design and installation requirements of the bottom of the vehicle 300. The connecting plate 40 is installed at the connection between the second section 22 and the sill beam structure 30, and the connecting plate 40 includes a first connecting section 41 and a second connecting section 42 connected to each other. The first connecting section 41 is connected to the second section 22 of the longitudinal beam structure 20, and the second connecting section 42 is connected to the sill beam structure 30. The vehicle body painting bracket 100 is located above the connecting plate 40 and is arranged at the connection between the first connecting section 41 and the second connecting section 42. The support portion 13 in the vehicle body painting bracket 100 is fixedly connected to the first connection section 41 of the connecting plate 40 in the vehicle body height direction Z, the first connection portion 15 on the first portion 11 is fixedly connected to the threshold beam structure 30 along the vehicle body width direction Y, and the second connection portion 16 on the second portion 12 is fixedly connected to the second section 22 of the longitudinal beam structure 20 along the vehicle body length direction X, so that the vehicle body painting bracket 100 simultaneously connects the longitudinal beam structure 20, the threshold beam structure 30 and the connecting plate 40 to form a triangular support structure in this area. The connecting plate 40 also includes a third connection section 43, which is arranged at one end of the first connection section 41 away from the second connection section 42, and is used to connect other structures of the vehicle body. The connecting plate 40 can also be a sheet metal part, and the first connection section 41, the second connection section 42 and the third connection section 43 are integrally formed.

[0085] Further, the first connecting section 41 includes a first connecting panel 411, a first upper side plate 412 and a first lower side plate 413. The first upper side plate 412 is connected to the second section 22 of the longitudinal beam structure 20, and the first lower side plate 413 is arranged on the side of the first connecting panel 411 away from the first upper side plate 412, and the first lower side plate 413 extends downward along the vehicle body height direction Z. The second section 22 of the longitudinal beam structure 20 also has an upper surface 221 and an upper side edge 222, and the upper side edge 222 of the second section 22 is located on the side of the upper surface 221 away from the connecting plate 40. The first upper side plate 412 of the first connecting section 41 is overlapped on the upper surface 221 of the second section 22. The second connecting portion 16 on the vehicle body painting bracket 100 is fixedly connected to the side plate of the second section 22 to fix the vehicle body painting bracket 100 and the longitudinal beam structure 20 in the vehicle body length direction X.

[0086] When there are multiple support parts 13, a part of the support parts 13 is fixedly connected to the first connection panel 411 and the first upper side plate 412 through the third connection part 14. Since the first upper side plate 412 overlaps the upper surface 221 of the second section 22, when the support part 13 is fixedly connected to the first upper side plate 412, it is also fixedly connected to the upper surface 221 of the second section 22 to fix the longitudinal beam structure 20, the connection plate 40 and the vehicle body painting bracket 100 in the vehicle body height direction Z. Another part of the support part 13 can extend downward along the vehicle body height direction Z and be fixedly connected to the first lower side plate 413 of the first connection section 41 to improve the connection reliability between the vehicle body painting bracket 100 and the connection plate 40.

[0087] Further, the second connection section 42 includes a second connection panel 421, a second upper side panel 422 and a second lower side panel 423, which are respectively arranged corresponding to the first connection panel 411, the first upper side panel 412 and the second lower side panel 423, and are fixedly connected to the threshold beam structure 30. Specifically, the second upper side panel 422 is overlapped and fixed to the side panel of the threshold beam structure 30, and the second connection panel 421 and the second lower side panel 423 are overlapped and fixed to the inner protruding structure of the threshold beam structure 30. The first connection portion 15 on the vehicle body painting bracket 100 can also be fixedly connected to the second upper side panel 422 along the vehicle body width direction Y. Since the second upper side panel 422 is overlapped to the side panel of the threshold beam structure 30, when the first connection portion 15 is fixedly connected to the second upper side panel 422, it is also fixedly connected to the side panel of the threshold beam structure 30. Specifically, when there are two second connection parts 16, one of the first connection parts 15 is directly fixedly connected to the side panel of the rocker beam structure 30 along the vehicle body width direction Y, and the other first connection part 15 is fixedly connected to the side panel of the rocker beam structure 30 along the vehicle body width direction Y through the second upper side plate 422.

[0088] See also Figure 7 An embodiment of the present application further provides a vehicle 300 , including a vehicle body 301 and the vehicle body painting structure assembly 200 described in the above embodiment or combination of embodiments, wherein the vehicle body painting structure assembly 200 is installed on the vehicle body 301 .

[0089] The body painting bracket 100, body painting structure assembly 200 and vehicle 300 of the present application avoid opening holes on the longitudinal beam structure 20, the threshold beam structure 30 and the connecting plate 40, so as to solve the problem that the painting process holes weaken the strength of the front structure of the body and thus affect the collision force transmission path; the large-surface support form of the traditional hanging structure is changed through the direct force transmission design of the support part 13, the connecting part, etc., to improve the support efficiency, and greatly improve the support and bearing capacity of the painting structure in the height direction Z of the body, and solve the problem that the conventional body painting hanging point structure piles up materials or adds reinforcement plates in order to improve the strength of the painting hanging point, and the structure is bulky and costly. At the same time, the body painting bracket 100 structure of the present application can be installed and positioned through the support part, the connecting part and other structures, with good safety performance, light weight and easy assembly. The body painting bracket 100 bracket can be integrated with multiple process holes, with simple size, high processing precision, flexible design and low transfer cost.
