Technical Field

[0001] This utility model belongs to the field of automobile manufacturing technology, and more specifically, it relates to a steering column with an adjustable motor angle. Background Technology

[0002] The steering column is fixed to the instrument tube beam via upper and lower mounting points. Considering structural simplicity and strength, the industry designs the lower housing and lower mounting bracket of the steering column as a single unit, with the mold being a single die-cast aluminum alloy. Although the above design is simple in structure and has high strength, the motor position is fixed, resulting in poor cross-platform adaptability and making it difficult to borrow for new projects, thus generating high mold costs and mold development cycles.

[0003] Disadvantages of existing technology: The fixed position of the motor leads to poor cross-platform compatibility; new projects cannot use the same mold and need to create new molds, which increases costs and time; aluminum alloy die-casting molds are highly complex and have high costs for batch rework.

[0004] To address the aforementioned technical problems, this application proposes a solution. Utility Model Content

The outer mounting bracket is perpendicular to the fixing plate. The fixing plate has a groove in the middle, and an inner mounting bracket is rotatably connected in the groove. The inner mounting bracket is a semi-enclosed structure. Two mounting holes for fixing to the vehicle body are opened at the closed end of the inner mounting bracket. The open end of the inner mounting bracket abuts against the outer surface of the upper column housing. Sliding grooves are opened on both sides of the middle of the outer mounting bracket. Fastening bolts are slidably connected in the sliding grooves. The fastening bolts pass through the inner mounting bracket. A wrench is fixedly connected to one end of the fastening bolt, and a spring is fixedly connected to the other end of the fastening bolt. One end of the spring is fixedly connected to the outer mounting bracket.

[0009] Preferably, the wrench is fixedly connected to a second tooth on the side near the outer mounting bracket, and the fastening bolt is provided with a matching first tooth on the side near the second tooth.

[0010] Preferably, the upper tube column housing has a U-shaped plate fixedly connected to the upper tube column housing on the edge near the fixing plate, and the two sides of the opening of the U-shaped plate abut against the outer mounting frame.

[0011] Preferably, the U-shaped plate and the fastening bolt are located on both sides of the upper tube column housing, and the fastening bolt abuts against the upper tube column housing.

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] like Figures 1 to 7 As shown, an adjustable steering column includes an upper column housing 5. A housing 4 is fixedly connected to one end of the upper column housing 5. A motor 2 is fixedly connected to one side of the housing 4. Three sets of symmetrical limiting holes 401 are formed at both ends of one end of the housing 4. A mounting bracket 3, fixedly connected to the housing 4, is provided at one end of each limiting hole 401. By installing the mounting bracket 3 in different sets of limiting holes 401, the installation position of the steering column can be adjusted, facilitating installation on different vehicle models, increasing versatility, and saving costs. A fixing plate 1 is fixedly connected to the middle position of the upper column housing 5.

[0026] like Figure 7 As shown, the mounting bracket 3 includes a fixing frame 301. One side of the fixing frame 301 has a shaft hole 302 for fixing to the vehicle body. Mounting ears 303 are fixedly connected to both ends of the fixing frame 301, and bolts 304 are provided on the mounting ears 303 for fixing to the shaft hole 302. After determining the installation position of the steering column, the mounting bracket 3 is adjusted according to the position so that it can be fixed to both the vehicle body and the steering column.

[0027] The fixing plate 1 has mounting holes 101 at both ends for fixing to the vehicle body. An outer mounting bracket 106 is fixedly connected in the middle of the fixing plate 1. The outer mounting bracket 106 is perpendicular to the fixing plate 1. The fixing plate 1 has a groove in the middle, and an inner mounting bracket 102 is rotatably connected in the groove. The inner mounting bracket 102 is a semi-closed structure. Two mounting holes 103 for fixing to the vehicle body are opened at the closed end of the inner mounting bracket 102. The open end of the inner mounting bracket 102 abuts against the outer surface of the upper column housing 5. The outer mounting bracket 106 has sliding grooves 106A on both sides in the middle. A fastening bolt 104 is slidably connected in the sliding groove 106A. The fastening bolt 104 passes through the inner mounting bracket 102. A wrench 6 is fixedly connected to one end of the fastening bolt 104. A spring 105 is fixedly connected to the other end of the fastening bolt 104. One end of the spring is fixedly connected to the outer mounting bracket 106. The spring 105 pulls the fastening bolt 104, so that the fastening bolt 104 always abuts against the upper column housing 5, thereby fixing the upper column housing 5. The wrench 6 is fixedly connected to the side of the outer mounting bracket 106 with a second spline tooth 601, and the fastening bolt 104 is provided with a matching spline tooth 104A on the side of the side of the second spline tooth 601. When the fastening bolt 104 abuts against the upper tube column housing 5, the wrench 6 is rotated to fasten and fix the outer mounting bracket 106 and the inner mounting bracket 102 to prevent the upper tube column housing 5 from moving.

[0028] The upper tubular column housing 5 has a U-shaped plate 7 fixedly connected to the fixed plate 1 on one edge. The two sides of the opening of the U-shaped plate 7 abut against the outer mounting bracket 106. The U-shaped plate 7, located above the outer mounting bracket 106, can maintain the relative position of the upper tubular column housing 5 and the outer mounting bracket 106, while also allowing the upper tubular column housing 5 to rotate and adjust its position within the outer mounting bracket 106, facilitating installation. The U-shaped plate 7 and the fastening bolts 104 are located on both sides of the upper tubular column housing 5, and the fastening bolts 104 abut against the upper tubular column housing 5. An upper drive shaft 501 is rotatably connected inside the upper tubular column housing 5. One end of the upper drive shaft 501 is located inside the housing 4 and meshes with the motor 2 for transmission. The function of the motor 2 is to synchronously drive the upper drive shaft 501 to rotate when the upper drive shaft 501 rotates, providing assistance.

Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
