[0027] The embodiments of the present invention will be described in detail below. The embodiments described with reference to the drawings are exemplary. Below, reference is made to Figure 1 - Figure 2 Describe the connecting bracket 100 according to the embodiment of the present invention. The connecting bracket 100 includes: a first bracket 10 and a second bracket 30.

[0028] Specifically, as Figure 1 shown, the first bracket 10 is connected to the second bracket 30. Both the first bracket 10 and the second bracket 30 include a first connecting plate 11 and a second connecting plate 12. The two first connecting plates 11 are connected to each other. The two second connecting plates 12 are connected to the corresponding first connecting plate 11 on the side where the two first connecting plates 11 are away from each other. The connecting bracket 100 has a first direction A and a second direction B, and the first direction A and the second direction B are perpendicular.

[0029] The first bracket 10 and the second bracket 30 are arranged along the first direction A and are connected to each other. The connecting bracket 100 formed by connecting the first bracket 10 and the second bracket 30 is symmetrically arranged along the first direction A and the second direction B respectively. The first bracket 10 and the second bracket 30 are independently designed and connected, and the connection method can be welding. The first bracket 10 and the second bracket 30 can be formed by stamping.

[0030] In this embodiment, the first bracket 10 and the second bracket 30 with thin-walled structures are formed by a stamping process. The first bracket 10 and the second bracket 30 are two identical and symmetrical structures. When the first bracket 10 and the second bracket 30 are connected, the two ends of the first bracket 10 and the second bracket 30 extend in directions away from each other. Both the first bracket 10 and the second bracket 30 include a first connecting plate 11 and a second connecting plate 12, and the first connecting plate 11 of the first bracket 10 and the first connecting plate 11 of the second bracket 30 are connected to each other. The connection method can be welding. The second connecting plate 12 of the first bracket 10 and the second connecting plate 12 of the second bracket 30 are respectively vertically connected to the corresponding first connecting plate 11 and are located on one side where the first connecting plates 11 of the first bracket 10 and the second bracket 30 are away from each other, simplifying the structures of the first bracket 10 and the second bracket 30 and improving their structural strength.

[0031] For the connecting bracket 100 according to the embodiment of the present invention, the first bracket 10 and the second bracket 30 are connected by two first connecting plates 11, and the first connecting plates 11 and the second connecting plates 12 in the first bracket 10 and the second bracket 30 are connected to each other, simplifying the structure of the connecting bracket 100, contributing to the lightweight design of the connecting bracket 100, reducing the design requirements of the connecting bracket 100, improving the bending resistance and torsional resistance of the first bracket 10 and the second bracket 30 in the first direction A and the second direction B, making the structure of the connecting bracket 100 stronger and the processing cost lower; and because the first bracket 10 and the second bracket 30 are symmetrically arranged, the connecting bracket 100 is uniformly stressed in the first direction A and the second direction B, improving the overall structural strength of the connecting bracket 100 and increasing the service life of the connecting bracket 100.

[0032] According to some embodiments of the present invention, as Figure 1 shown, the distance between the two ends of the two first connecting plates 11 gradually increases in the direction away from each other along the first direction A, and the extending direction of the second connecting plate 12 is adapted to that of the first connecting plate 11.

[0033] In this embodiment, taking the first bracket 10 as an example, the distance between the two ends of the first connecting plate 11 of the first bracket 10 gradually increases in the direction away from the second bracket 30 along the first direction A, that is, the two ends of the first connecting plate 11 of the first bracket 10 extend along the second direction B and are inclined in the direction away from the second bracket 30. The second connecting plate 12 is connected to the first connecting plate 11 on the side where the first connecting plate 11 is away from the second bracket 30, and the two ends of the second connecting plate 12 extend along the second direction B and are inclined in the direction away from the second bracket 30.

[0034] The first connecting plate 11 extends along the second direction B and along the third direction C, and the second direction B and the third direction C are perpendicular. The second connecting plate 12 extends along the second direction B and along the first direction A. For example, the width of the first connecting plate 11 in the first direction A is less than or equal to the width of the second connecting plate 12 in the first direction A, and the height of the first connecting plate 11 in the third direction C is greater than or equal to the width of the second connecting plate 12 in the third direction C. The first connecting plate 11 and the second connecting plate 12 are vertically connected in the first direction A. Thus, the arrangement of the first connecting plate 11 can increase the force on the connecting bracket 100 in the third direction C, and the arrangement of the second connecting plate 12 can increase the force on the connecting bracket 100 in the first direction A.

[0035] Therefore, the distance between the two ends of the two first connecting plates 11 gradually increases in the direction away from each other along the first direction A, and the extending direction of the second connecting plate 12 is adapted to that of the first connecting plate 11, which can increase the structural strength of the connecting bracket 100, improve the adaptability between the first connecting plate 11 and the second connecting plate 12 at the same time, facilitate the connection between the first bracket 10 and the second bracket 30 of the connecting bracket 100 and the vehicle frame 200, avoid stress concentration on the first connecting plate 11 and the second connecting plate 12, and improve the stability of the connecting bracket 100; at the same time, the second connecting plate 12 is vertically connected to the first connecting plate 11, which can effectively improve the anti-torsion ability of the first bracket 10 and improve the overall structural strength of the connecting bracket 100.

[0036] According to some embodiments of the present invention, as Figure 1 shown, the first connecting plate 11 includes: a first plate body 111 and two second plate bodies 112. One ends of the two second plate bodies 112 are respectively connected to the two ends of the first plate body 111, and the other ends of the two second plate bodies 112 extend obliquely in the direction away from the second bracket 30 along the second direction B. The first direction A and the second direction B are perpendicular.

[0037] That is, the first connecting plate 11 of the first bracket 10 and the second bracket 30 both includes a first plate body 111 and two second plate bodies 112 that are connected to each other. Among them, the first plate body 111 is disposed between the two second plate bodies 112. One ends of the two second plate bodies 112 are respectively connected to the two ends of the first plate body 111, and the other ends of the two second plate bodies 112 extend obliquely in the direction away from the second bracket 30 along the first direction A. The first plate body 111 extends along the second direction B, and the first connecting plates 11 of the first bracket 10 and the second bracket 30 are welded and connected through the corresponding first plate bodies 111. The two second plate bodies 112 can be formed by the two ends of the first plate body 111 along the second direction B extending obliquely in the direction away from the second bracket 30.

[0038] Thus, the setting of the first plate body 111 facilitates the connection between the first bracket 10 and the second bracket 30, improving the structural strength of the connection. The two second plate bodies 112 are obliquely connected to the first plate body 111, which can avoid stress concentration on the first connecting plate 11, facilitate the dispersion of the stress of the connecting bracket 100, improve the structural stability of the first connecting plate 11, facilitate the connection between the connecting bracket 100 and the vehicle frame 200, and reduce the manufacturing precision requirements for the connecting bracket 100.

[0039] According to some embodiments of the present invention, as Figure 1 shown, the included angle between the second plate body 112 and the first plate body 111 is α, and α satisfies: 30° ≤ α ≤ 60°.

[0040] That is, in this embodiment, taking the first plate body 111 and the second plate body 112 included in the first connecting plate 11 of the first bracket 10 as an example, the first plate body 111 extends along the second direction B, and one end of the second plate body 112 far from the first plate body 111 extends along the second direction B and is inclined towards the direction away from the second bracket 30. The included angle between the first plate body 111 and the second plate body 112 is α = 45°. If the included angle between the second plate body 112 and the first plate body 111 is less than 30°, the included angle between the second plate body 112 and the first plate body 111 is too small, and the second plate body 112 is almost perpendicular to the first plate body 111, which may cause stress concentration on the two second plate bodies 112 in the first connecting plate 11, resulting in bending or fracture of the first connecting plate 11, and is not conducive to increasing the anti-torsion ability of the connecting bracket 100 in the second direction B. At the same time, it is not convenient for the setting of the second connecting plate 12 and the connection between the connecting bracket 100 and the vehicle frame 200 in the second direction B, which will cause the width of the connecting bracket 100 in the second direction B to be smaller, resulting in inability to be installed with the vehicle frame 200. If the included angle between the second plate body 112 and the first plate body 111 is greater than 60°, the included angle between the second plate body 112 and the first plate body 111 is too large, and the lengths of the two second plate bodies 112 increase, resulting in a decrease in the structural strength of the first connecting plate 11, especially reducing the force on the connecting bracket 100 in the first direction A, and at the same time increasing the cost of the connecting bracket 100.

[0041] Thus, limiting the included angle range between the second plate body 112 and the first plate body 111 can avoid stress concentration on the first connecting plate 11, make the stress evenly distributed on the first connecting plate 11, facilitate improving the structural strength of the first connecting plate 11, so as to increase the bending resistance characteristics of the connecting bracket 100 in the first direction A and the second direction B, and at the same time facilitate the setting of the second connecting plate 12 on the first connecting plate 11, saving the material cost of the connecting bracket 100.

[0042] According to some embodiments of the present invention, as Figure 1As shown, the second connecting plate 12 includes: a third plate body 121 and two fourth plate bodies 122. One end of each of the two fourth plate bodies 122 is connected to both ends of the third plate body 121 respectively, and the other ends of the two fourth plate bodies 122 extend obliquely away from the second bracket 30 in the second direction B.

[0043] In this embodiment, both the first bracket 10 and the second bracket 30 include the second connecting plate 12. Taking the first bracket 10 as an example, the two fourth plate bodies 122 are respectively arranged at both ends of the third plate body 121 along the second direction B and are connected to the third plate body 121. While the ends of the two fourth plate bodies 122 away from the third plate body 121 extend along the second direction B, they are inclined in the direction away from the second bracket 30. The extending direction and bending direction of the first connecting plate 11 are the same as the extending and bending directions of the second connecting plate 12. Thus, the setting of the second connecting plate 12 can increase the structural strength of the first connecting plate 11 and at the same time increase the force on the connecting bracket 100 in the first direction A.

[0044] According to some embodiments of the present utility model, as Figure 1 shown, the third plate body 121 is in contact with and connected to the first plate body 111, and the two fourth plate bodies 122 are respectively in contact with and connected to the two second plate bodies 112.

[0045] In this embodiment, the first plate bodies 111 included in the first bracket 10 and the second bracket 30 are connected to each other. The third plate bodies 121 included in the first bracket 10 and the second bracket 30 are respectively arranged on one side of the two first plate bodies 111 away from each other along the first direction A and are respectively connected to the first plate bodies 111. The adjacent ends of the two second plate bodies 112 adjacent to each other along the first direction A are abutted or connected to each other, and the other ends of the two second plate bodies 112 extend along the second direction B and are inclined in the direction away from each other. The fourth plate bodies 122 of the second connecting plate 12 are connected to the corresponding second plate bodies 112 on one side where the two adjacent second plate bodies 112 are away from each other.

[0046] Thus, the third plate body 121 and the two fourth plate bodies 122 are perpendicularly connected to the first plate body 111 and the two second plate bodies 112 respectively along the first direction A to improve the overall structural strength and force-bearing capacity of the first connecting plate 11, avoid deformation of the first bracket 10 and the second bracket 30, and further improve the overall structural strength of the connecting bracket 100.

[0047] Optionally, the second connecting plate 12 is connected to the first connecting plate 11 at a position in the middle of the first connecting plate 11, and the first connecting plate 11 is symmetrically arranged about the second connecting plate 12 along the third direction C, so that the connecting bracket 100 can be evenly stressed when stressed, ensure the structural strength of the connecting bracket 100, avoid uneven stress on the upper and lower sides of the first connecting plate 11, and increase the structural strength of the connecting bracket 100.

[0048] According to some embodiments of the present utility model, as Figure 1 shown, from the other end of the fourth plate body 122, that is, the end far from the third plate body 121, to one end of the fourth plate body 122, that is, the end connected to the third plate body 121, the cross-sectional area of the fourth plate body 122 gradually increases.

[0049] In this embodiment, taking the first bracket 10 as an example, for the second connecting plate 12, the cross-sectional area of the fourth plate body 122 gradually decreases from the end connected to the third plate body 121 to the end far from the third plate body 121. Specifically, for example, the width of the fourth plate body 122 gradually decreases in the direction away from the third plate body 121, which is convenient for the second connecting plate 12 to be adapted to the first connecting plate 11, and increases the structural strength at the connection of the first bracket 10 and the second bracket 30.

[0050] Thus, from the end of the fourth plate body 122 far from the third plate body 121 to the end of the fourth plate body 122 adjacent to the third plate body 121, the cross-sectional area of the fourth plate body 122 gradually increases. The overall cross-section of the fourth plate body 122 adopts a variable cross-section design, so that different parts of the fourth plate body 122 bear appropriate forces, thereby realizing the structural optimization of the first bracket 10, effectively improving the anti-torsion ability of the first bracket 10 in the first direction A and the second direction B, effectively improving the structural strength of the connecting bracket 100, while reducing the weight of the connecting bracket 100 and saving the cost of the connecting bracket 100.

[0051] According to some embodiments of the present utility model, mounting grooves are respectively formed at both ends of the first connecting plate 11, and the bottom surface of the mounting groove is an arc surface;

[0052] In this embodiment, taking the first bracket 10 as an example, in combination with Figure 1 , the mounting groove includes a first mounting groove and a second mounting groove. The first mounting groove and the second mounting groove are respectively formed at both ends of the first connecting plate 11 and are located at the end of the first connecting plate 11, specifically at the end face of the end of the first connecting plate 11, that is, the first mounting groove and the second mounting groove are respectively arranged on the end face of the second plate body 112. When forming the first mounting groove and the second mounting groove, they are recessed from the corresponding end face along the extending direction of the second plate body 112 towards the end where the second plate body 112 is connected to the first plate body 111, and the first mounting groove and the second mounting groove penetrate through the second plate body 112 along the thickness direction of the second plate body 112. The bottom surface of the mounting groove is an arc surface.

[0053] Optionally, as Figure 1 shown, the connecting bracket 100 further includes: an annular structural member 20, the annular structural member 20 cooperates with the mounting groove, and the outer surface of the annular structural member 20 is adapted to the arc surface.

[0054] In this embodiment, the annular structural member 20 is adapted to be installed at the installation groove. The annular structural member 20 includes a first annular structural member 201 and a second annular structural member 202. The outer surface of the first annular structural member 201 is attached to the arc surface of the first installation groove, so that the first annular structural member 201 cooperates with the first installation groove; the outer surface of the second annular structural member 202 is attached to the arc surface of the second installation groove, so that the second annular structural member 202 cooperates with the second installation groove.

[0055] Thus, the arrangement of the installation groove facilitates the cooperation between the annular structural member 20 and the installation groove, so that the connection bracket 100 is connected to the vehicle frame 200 through the annular structural member 20, improving the connection efficiency and connection accuracy of the connection bracket 100 on the vehicle frame 200 and simplifying the structure when the connection bracket 100 is connected to the vehicle frame 200.

[0056] After the annular structural member 20 is fitted with the installation groove, it is fixedly connected by welding at the connection. The rotation center line of the annular structural member 20 and the central plane of the second connecting plate 12 along the third direction C are located on the same layer. Wherein, the annular structural member 20 and the connection bracket 100 are integrally formed.

[0057] When the connection bracket 100 is connected to the vehicle frame 200 of the vehicle, as Figure 2 shown, it further includes a flexible ball joint. The flexible ball joint is arranged inside the annular structural member 20 and extends out of both ends of the annular structural member 20 along the center line of the annular structure, so as to facilitate connection with the vehicle frame 200 and simplify the connection structure. At the same time, the influence of the vibration of the vehicle frame 200 on the structure of the connection bracket 100 is reduced.

[0058] According to some embodiments of the present invention, as Figure 1 and Figure 2 shown, the first bracket 10 and the second bracket 30 are arranged in an "X" shape.

[0059] That is, the first bracket 10 and the second bracket 30 are connected along the first direction A of the connecting bracket 100. The shape of the connecting bracket 100 can be approximately designed in an "X" shape. The connecting bracket 100 is designed with an X-shaped structure. For example, the first connecting plate 11 of the first bracket 10 and the first connecting plate 11 of the second bracket 30 are connected to each other. Among them, the first plate bodies 111 of the two first connecting plates 11 are connected to each other along the first direction A. The second plate bodies 112 provided at the same end of the two first plate bodies 111 along the second direction B extend away from the first plate bodies 111 in a direction away from each other. That is, an included angle is formed between the two second plate bodies 112 opposite to each other along the first direction A of the two first connecting plates 11. In this embodiment, the two second plate bodies 112 opposite to each other and adjacent to each other along the first direction A are perpendicular to each other. Similarly, the second plate bodies 112 connected to the other ends of the two first plate bodies 111 along the second direction B are inclined and extended in a direction away from each other at the ends away from the first plate bodies 111. The connecting bracket 100 is symmetrically arranged along both the first direction A and the second direction B.

[0060] The connecting bracket 100 is arranged in this way so that the connecting bracket 100 can be stressed evenly and is suitable for the vehicle frame 200 with a high-load-bearing structure. Compared with the traditional V-shaped thrust rod that must be used in cooperation with the lateral stabilizer bar, the X-shaped connecting bracket 100 eliminates the lateral stabilizer bar and has more assembly positions on the vehicle frame 200. And in this embodiment, the connecting bracket 100 is welded by the first bracket 10 and the second bracket 30, with a simple process, low cost, and it is easy to change the angles of the first bracket 10 and the second bracket 30 to facilitate application in more occasions.

[0061] Therefore, the first bracket 10 and the second bracket 30 are designed in an "X" shape, which improves the integrated design of the connecting bracket 100, improves the connection efficiency and stability of the connecting bracket 100, improves the generalization degree of the connecting bracket 100 and the processing die, reduces the number of parts, and on the premise of realizing the lightweight design of the connecting bracket 100, the connecting bracket 100 can be quickly mass-produced, reducing the production cost and reducing the weight of the vehicle.

[0062] According to the vehicle of the second aspect embodiment of the present invention, as Figure 2 shown, it includes the connecting bracket 100 in the above embodiment.
