[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] The following is combined Figures 1-6 Description of the present invention: Automotive steering gear bracket

[0033] like Figures 1 to 6 As shown, this utility model provides an automotive steering gear bracket, including: a bracket body 1, which includes a frame connecting portion 11 and a steering gear connecting portion 12 connected together. The end face of the frame connecting portion 11 away from the steering gear connecting portion 12 includes a first end face 111 and a second end face 112, the height of the first end face 111 being greater than the height of the second end face 112. The frame connecting portion 11 is configured to connect to the frame via the first end face 111 and the second end face 112 respectively. The steering gear connecting portion 12 is used to connect to the steering gear.

[0034] In this embodiment, the bracket body 1 includes a connected frame connecting portion 11 and a steering gear connecting portion 12. The frame connecting portion 11 is used to connect to the frame, and the steering gear connecting portion 12 is used to connect to the steering gear, so as to install and fix the steering gear on the frame. Specifically, the end face of the frame connecting portion 11 away from the steering gear connecting portion 12 includes a first end face 111 and a second end face 112 with a height difference. It is understood that the height in this embodiment refers to the distance from the first end face 111 or the second end face 112 to the frame connecting portion 11. The frame connecting portion 11 is connected to different planes of the frame through the first end face 111 and the second end face 112, so that the multiple connection points between the frame connecting portion 11 and the frame are not located on the same plane, which helps to improve the connection strength between the bracket body 1 and the frame and the fastening effect is better.

[0035] This utility model discloses an automotive steering gear bracket. The bracket body 1 is divided into a frame connection portion 11 and a steering gear connection portion 12, which are respectively connected and fixed to the frame and the steering gear, thereby securing the steering gear to the frame. Simultaneously, by providing a first end face 111 and a second end face 112 with a height difference on the frame connection portion 11, and by connecting and fixing the first end face 111 and the second end face 112 to different planes on the frame, the connection strength and fastening effect between the frame connection portion 11 and the frame are improved, effectively solving the defects of low connection strength and poor fixing effect in existing brackets. Furthermore, it is understood that the first end face 111 and the second end face 112 of the frame connection portion 11 can also better adapt to irregularly shaped frame structures, making the automotive steering gear bracket fit more tightly to the frame, resulting in a more compact structure and less space occupation.

[0036] It is understood that the frame connection part 11 may include two independent structures, and the first end face 111 and the second end face 112 may be the end faces on the two independent structures respectively; or, the frame connection part 11 may be an integral structure, and the first end face 111 and the second end face 112 may be the stepped parallel surfaces on the integral structure.

[0037] Specifically, in some embodiments, such as Figure 1 , Figure 3 and Figure 4 As shown, the end face of the frame connection portion 11 away from the steering gear connection portion 12 also includes a transition connection surface 113, and the first end face 111 and the second end face 112 are connected through the transition connection surface 113.

[0038] In this embodiment, the first end face 111 and the second end face 112 are connected by a transition connecting surface 113, so that the first end face 111 and the second end face 112 can be connected into a whole, thereby allowing the first end face 111, the second end face 112 and the transition connecting surface 113 to fit together on the frame, thereby increasing the contact area between the frame connecting part 11 and the frame, which is beneficial to improving the connection strength between the frame connecting part 11 and the frame.

[0039] Furthermore, in some embodiments, such as Figure 1 , Figure 3 and Figure 4 As shown, the transition connection surface 113 includes a first arc surface 1131, a transition slope 1132, and a second arc surface 1133 connected in sequence. The first arc surface 1131 is connected to the first end face 111. The second arc surface 1133 is connected to the second end face 112.

[0040] In this embodiment, by providing a first arc surface 1131, a transition slope 1132, and a second arc surface 1133 between the first end face 111 and the second end face 112, the transition between the first end face 111 and the second end face 112 is made smoother, reducing stress concentration.

[0041] In some embodiments, such as Figure 1 , Figure 2 and Figure 5 As shown, the frame connection part 11 is provided with mounting holes for fasteners to be inserted and fixedly installed on the frame.

[0042] In this embodiment, mounting holes are provided on the frame connection part 11 for fasteners such as bolts to pass through, so that the frame connection part 11 can be installed on the frame. The structure is simple and easy to assemble and disassemble.

[0043] Specifically, in some embodiments, such as Figure 1 , Figure 2 and Figure 5 As shown, the mounting holes include a plurality of first mounting holes 114 and a plurality of second mounting holes 115. The first mounting holes 114 are arranged along the length of the first end face 111. The second mounting holes 115 are arranged along the length of the second end face 112.

[0044] In this embodiment, by arranging multiple first mounting holes 114 along the length of the first end face 111 and multiple second mounting holes 115 along the length of the second end face 112, the connection points between the frame connection part 11 and the frame can be distributed on the first end face 111 and the second end face 112, making the stress points of the frame connection part 11 more dispersed and more uniform, and making the connection strength between the entire car steering bracket and the frame higher and the load-bearing capacity stronger.

[0045] Specifically, in some embodiments, the length direction of the first end face 111 is parallel to the length direction of the second end face 112.

[0046] In this embodiment, by arranging the length direction of the first end face 111 parallel to the length direction of the second end face 112, the structures of the first end face 111 and the second end face 112 can be arranged more compactly, thereby reducing the overall area occupied by the first end face 111 and the second end face 112, which is beneficial to reducing the space occupied by the entire car steering gear bracket.

[0047] In some embodiments, such as Figure 2 and Figure 6 As shown, the steering gear connection part 12 is provided with a clearance groove 121, which is used to accommodate the output shaft of the steering gear.

[0048] In this embodiment, by providing a clearance groove 121 on the steering gear connection part 12, the output shaft of the steering gear can be inserted into the clearance groove 121 through the slot of the clearance groove 121 and rotate freely within the clearance groove 121 without affecting the normal operation of the steering gear. At the same time, the connection between the steering gear connection part 12 and the steering gear is more compact, and the overall structure of the car steering gear bracket and the steering gear occupies less space.

[0049] It is understandable that the groove wall of the clearance groove 121 and the side wall of the entire bracket body 1 opposite to the output shaft of the steering gear need to be designed according to the movement trajectory of the output shaft and the rocker arm on the output shaft. If necessary, grooves can be set on the groove wall of the clearance groove 121 or the side wall of the bracket body 1 to ensure that there is sufficient clearance between the entire bracket body 1 and the output shaft and the rocker arm.

[0050] Specifically, in some embodiments, the wall of the clearance groove 121 is a regular arc-shaped groove wall without sharp edges, so as to reduce stress concentration in the groove wall.

[0051] In some embodiments, such as Figure 3 and Figure 6 As shown, the end face of the steering gear connection portion 12 away from the frame connection portion 11 is angled to the first end face 111, and the steering gear connection portion 12 is connected to the steering gear through this end face.

[0052] In this embodiment, the steering gear is connected to the end of the steering gear connection 12 away from the frame connection 11. By tilting the end face of the steering gear connection 12 relative to the first end face 111, the end face of the steering gear connection 12 can better fit and connect with the steering gear, making the steering gear and the steering gear connection 12 more compact and occupying less space overall.

[0053] Specifically, in some embodiments, the angle between the steering gear connection 12 and the first end face 111 is 3°.

[0054] In some embodiments, such as Figure 1 , Figure 2 and Figure 5 As shown, the steering gear connection portion 12 is provided with a plurality of third mounting holes 122, which are arranged at intervals along the edge of the end face 11 of the steering gear connection portion 12 away from the frame connection portion. The third mounting holes 122 are used to insert fasteners for fixed connection with the steering gear.

[0055] In this embodiment, by arranging multiple third mounting holes 122 at intervals along the edge of the end face of the steering gear connection portion 12, the third mounting holes 122 can be used to install fasteners such as bolts for fixing to the steering gear. This allows the connection points between the steering gear connection portion 12 and the steering gear to be distributed across the end face of the steering gear connection portion 12, making the stress points of the steering gear connection portion 12 more dispersed and uniform, resulting in higher connection strength and stronger load-bearing capacity between the entire vehicle steering gear bracket and the steering gear.

[0056] In one specific embodiment, such as Figure 1 and Figure 2 As shown, a third mounting hole 122 is provided on the end face of the steering gear connection part 12 near each of the four corners.

[0057] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a weight-reducing cavity 13 is provided inside the support body 1. In this embodiment, by providing a weight-reducing cavity 13 inside the support body 1, the weight of the support body 1 can be effectively reduced, while stress concentration in the casting can be reduced.

[0058] In some embodiments, the weight reduction cavity 13 is a through cavity, with one end of the weight reduction cavity 13 penetrating through the end face of the frame connection portion 11 and the other end penetrating through the end face of the steering gear connection portion 12.

[0059] Specifically, in some embodiments, the first end face 111, the second end face 112, and the end of the steering gear connecting part 12 connected to the steering gear are provided with countersunk surfaces to facilitate processing.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
