Description

Technical Field

[0001] This utility model relates to the field of vehicle parts, specifically to an arched combined welding bracket for vehicles. Background Technology

[0002] In the field of vehicle metal parts, small-sized modular brackets are widely used for the support and fixation of various components, and their structural reliability directly affects the overall assembly stability of the vehicle.

[0003] Existing small-sized modular supports mostly employ single welding or simple tongue-and-groove snap-fit ​​connections. While single welding ensures connection strength, inaccurate positioning during assembly can easily lead to weld misalignment, and stress concentration during welding can cause support deformation. Simple tongue-and-groove snap-fit ​​connections, while convenient for quick positioning, suffer from loosening due to vibration during long-term use, resulting in insufficient connection reliability. Therefore, there is a need to design a small-sized modular welded support with a simple structure, precise positioning, and reliable connection. Utility Model Content

[0004] The problem to be solved by this utility model is to provide an arched combined welded bracket for vehicles.

[0005] To solve the above problems, this utility model provides an arched combined welded bracket for vehicles. To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problems is as follows: An arched combined welded bracket for vehicles includes: a central section, which is curved; and two side sections, which are mirror-symmetrically distributed on both sides of the central section and are perpendicularly fixed to each other. The central section and the side sections each include a rectangular protrusion and a rectangular notch that interlock with each other. Each side section is bent to form an upper plate, which is in surface contact with the surface of the central section. The interlocking parts of the central section and the side sections are provided with welds, and the edges of the contact parts between the upper plate and the central section are provided with welds.

[0006] As a further improvement of this utility model, the protrusion length of the rectangular protrusion of the middle piece is less than the thickness of the side piece.

[0007] As a further improvement of this utility model, the recess depth of the rectangular notch in the side piece is greater than the thickness of the middle piece.

[0008] As a further improvement of this utility model, a weld is filled between the top of the rectangular protrusion and the bottom surface of the assembled rectangular notch.

[0009] As a further improvement of this utility model, the edge of the upper plate and the surface of the middle plate have intermittent welds.

[0010] As a further improvement of this utility model, the upper plate has a through hole, the edge of the middle piece has a notch, and the through hole and the notch are coaxial.

[0011] As a further improvement of this utility model, the inner wall of the through hole is provided with internal threads.

[0012] As a further improvement of this utility model, the inner wall of the through hole and the inner wall of the notch are connected by a weld.

[0013] As a further improvement of this utility model, the front and back sides of the middle piece are respectively provided with convex curved surfaces and concave curved surfaces, and the upper plate is in contact with the side of the middle piece where the convex curved surface is located.

[0014] As a further improvement of this utility model, the middle part of the middle piece has a waist-shaped hole.

[0015] The beneficial technical effects of using the arched combined welded bracket for vehicles according to this application are: The rectangular protrusions and notches that interlock between the middle piece and the side pieces provide structural stability for the overall connection.

[0016] The upper plate formed by bending the side plate fits against the surface of the middle plate to form a surface contact. Compared with the point contact or line contact that may exist in traditional connection methods, it greatly increases the contact area between components, which can effectively disperse the stress generated during vehicle vibration, reduce the risk of loosening after long-term use, and make up for the lack of reliability of simple concave-convex snap-fit.

[0017] Welds are provided at the interlocking parts of the middle and side pieces, and at the contact points between the upper plate and the middle piece. This combines the positioning advantages of the interlocking parts with the high strength of the welds, ensuring connection strength while dispersing welding stress through multiple welds. This reduces deformation of the bracket caused by stress concentration, ultimately improving the structural strength of the entire vehicle bracket accessory.

[0018] The arched welded bracket for vehicles described in this application is generally used as part of the car seat adjustment frame, and its core function is to participate in the angle and position adjustment of the seat. The perforated mounting blocks at both ends are used for fixing to the seat frame and slide rails. The curved arc structure of the middle section adapts to the movement trajectory during seat adjustment while ensuring strength. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to specific embodiments: To achieve the purpose of this utility model, an arched combined welded bracket for vehicles includes: a central piece, which is in a curved arched shape; and two side pieces, which are mirror-symmetrically distributed on both sides of the central piece, and the central piece and the side pieces are fixed perpendicularly to each other. The central piece and the side pieces each include interlocking rectangular protrusions and rectangular notches. Each side piece has an upper plate formed by bending, and the upper plate is in surface contact with the surface of the central piece. Figures 5 to 7 As shown, the interlocking parts of the middle piece and the side piece are provided with welds, and the contact area between the upper plate and the middle piece is provided with welds along the edge.

[0023] like Figure 1 As shown, the middle piece 1 includes two parallel convex arms 103, with an inner recessed area 102 formed between the two convex arms 103, and the upper plate 203 forms a surface contact with the convex arms 103.

[0024] like Figure 2 , Figure 3 As shown, the side panel 2 is formed by an integral and perpendicular arc plate 202 and an upper plate 203. The arc plate 202 is a flat plate, but its overall shape is approximately an arc. Figure 2 , Figure 3 Two different side panels 2 are shown respectively.

[0025] Figure 2 , Figure 3 These are the side pieces 2 on the left and right sides of the central piece 1.

[0026] Figure 5 , Figure 6 , Figure 7 Fish scale pattern is used to represent weld seam 3.

[0027] The beneficial effects of adopting the above technical solution are: the middle piece 1 and the side piece 2 are fixed perpendicularly to each other, and the rectangular protrusion 105 of the middle piece 1 and the rectangular notch 201 of the side piece 2 interlock with each other, thus forming a three-dimensional and stable vehicle accessory by means of interlocking splicing.

[0028] But that's not all. The side piece 2 is also bent with an upper plate 203. The upper plate 203 can contact the surface of the middle piece 1, increasing the contact area between the middle piece 1 and the side piece 2 in different directions, further preventing the two from coming loose.

[0029] Based on the interlocking splicing, both the interlocking parts and the increased area of ​​the upper plate 203 facilitate the layout of weld seams 3, thereby improving the connection strength between the middle piece 1 and the side piece 2, and ultimately improving the structural strength of the entire vehicle accessory.

[0030] In some other embodiments of this invention, the protrusion length of the rectangular protrusion of the central piece is less than the thickness of the side pieces.

[0031] In some other embodiments of this invention, the recess depth of the rectangular notch in the side piece is greater than the thickness of the middle piece.

[0032] In some other embodiments of this invention, a weld is provided between the top of the rectangular protrusion and the bottom surface of the assembled rectangular notch.

[0033] The beneficial effects of adopting the above technical solution are: the dimensions of the protruding and recessed parts are intentionally set so that the interlocking parts do not form a smooth plane. This increases the welding contact area, strengthens the connection strength of the interlocking parts, further distributes the load, and improves the overall structural durability.

[0034] In some other embodiments of this invention, the edge of the upper plate and the surface of the middle plate have intermittent welds.

[0035] The beneficial effects of adopting the above technical solution are: the intermittent weld 3 between the edge of the upper plate 203 and the surface of the middle plate 1 reduces the heat stress concentration caused by continuous welding, reduces the risk of bracket deformation, and maintains sufficient connection strength, thus balancing welding reliability and manufacturing process.

[0036] In some other embodiments of this utility model, the upper plate has a through hole, and the edge of the middle piece has a notch, with the through hole and the notch being coaxial.

[0037] The beneficial effects of adopting the above technical solution are: it provides a unified installation reference point, which facilitates connection or fixation with other vehicle components and enhances the functionality and assembly convenience of the bracket.

[0038] like Figure 5 As shown, in some other embodiments of this utility model, the inner wall of the through hole has an internal thread.

[0039] The beneficial effect of adopting the above technical solution is that the internal thread allows for direct connection using bolts.

[0040] In some other embodiments of this invention, the inner wall of the through hole and the inner wall of the notch are connected by a weld.

[0041] The beneficial effect of adopting the above technical solution is that if the threaded assembly method is not used, the inner wall of the through hole 204 and the notch 104 is equivalent to adding another position where the weld can be arranged. The weld 3 fills the through hole 204 and the notch 104, which means that the middle piece 1 and the side piece 2 are fixed.

[0042] In some other embodiments of this utility model, the front and back sides of the middle piece are respectively provided with convex curved surfaces and concave curved surfaces, and the upper plate contacts the side of the middle piece where the convex curved surface is located.

[0043] like Figure 1 As shown, in some other embodiments of this utility model, the middle part of the middle piece has a waist-shaped hole.

[0044] The advantages of adopting the above technical solution are: it facilitates fine-tuning of the position during vehicle installation, enhances the adaptability and practicality of the bracket, and provides space for wiring or other components to pass through, thereby improving the compactness and functionality of the overall design.

[0045] In one embodiment, the central piece 1 and the side pieces 2 are de-sharpened and have their sharp corners removed. The thickness of the central piece 1 is less than the thickness of the side pieces 2.

[0046] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
