[0023] This utility model provides a mounting bracket for a steering device, comprising: a base plate and a fixing plate assembly. The steering device is mounted on one side of the base plate in a first direction; the fixing plate assembly includes multiple fixing plates, which are fixed to the other side of the base plate in the first direction. The fixing plates are arranged sequentially along a second direction. A limiting groove is formed on the side of the fixing plate in the first direction opposite to the steering device.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0037] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0039] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0040] like Figures 1 to 5 As shown, this utility model provides a mounting bracket 100 for a steering device, comprising: a base plate 1 and a fixing plate assembly 2. The steering device 200 is mounted on one side of the base plate 1 in a first direction X; the fixing plate assembly 2 includes multiple fixing plates, which are fixed to the other side of the base plate 1 in the first direction X. The multiple fixing plates are arranged sequentially along a second direction Y. A limiting groove 201 is formed on the side of the fixing plate in the first direction X opposite to the steering device 200. The limiting groove 201 is used to install a bridge tube 300. The axial direction of the bridge tube 300 is parallel to the second direction Y. The bridge tube 300 is inserted into the limiting groove 201, and a portion of the outer sidewall of the bridge tube 300 is tightly attached to and fixed to the inner sidewall of the limiting groove 201. The first direction X is perpendicular to the second direction Y.

[0041] With this configuration, the bridge tube 300 and the steering device 200 are spaced apart in the first direction X and fixed to the steering device mounting bracket 100, reducing interference during assembly. The limiting groove 201 in the fixing plate positions the bridge tube 300 during assembly, allowing it to be installed relatively accurately on the steering device mounting bracket 100. The outer wall of the bridge tube 300 is tightly fitted and fixed to the inner wall of the limiting groove 201, reducing the gap between the bridge tube 300 and the fixing plate. Furthermore, the fixing plate has multiple connections along the second direction Y, creating multiple connection points between the steering device mounting bracket 100 and the bridge tube 300, making their fixing relationship more reliable and maintaining the relative stability of the steering device 200 and the bridge tube 300 mounted on the steering device mounting bracket 100.

[0042] For example, the bridge tube 300 is cylindrical with a circular outer wall and the inner wall of the limiting groove 201 is a corresponding arc shape, so that the inner wall of the limiting groove 201 can fit with the outer wall of the bridge tube 300. Due to the lack of gap, the two are not suitable for relative movement.

[0043] Furthermore, the substrate 1 supports the steering device 200 below the steering device 200, reducing the suspended area of ​​the steering device 200.

[0044] Optionally, the fixing plate assembly 2 includes a first fixing plate A21 and a first fixing plate B22. The first fixing plate A21 is fixed to one end face of the substrate 1 in the second direction Y, and the first fixing plate B22 is fixed to the other end face of the substrate 1 in the second direction Y.

[0045] Optionally, the fixing plate assembly 2 also includes a second fixing plate A23 and a second fixing plate B24. Along the second direction Y, the first fixing plate A21, the second fixing plate A23, the second fixing plate B24 and the first fixing plate B22 are arranged in sequence. A first mounting part 11 is formed between the first fixing plate A21 and the second fixing plate A23, and a second mounting part 12 is formed between the second fixing plate B24 and the first fixing plate B22. The steering device 200 is connected to the base plate 1 through threaded fasteners at the first mounting part 11 and the second mounting part 12 respectively.

[0046] With this configuration, the first mounting part 11 and the second mounting part 12 are located at opposite ends of the second direction Y, and the steering device 200 is fixed to the base plate 1 at the first mounting part 11 and the second mounting part 12, respectively. This results in a larger support range of the base plate 1 for the steering device 200 in the second direction Y, which can reduce the shaking between the base plate 1 and the steering device 200.

[0047] Furthermore, the steering device 200 is connected to the base plate 1 by threaded fasteners, making the assembly simple and easy to disassemble and maintain.

[0048] Optionally, the substrate 1 has slots A13 and B14 on its edge in the first direction X, a second fixing plate A23 is inserted into slot A13, and a second fixing plate B24 is inserted into slot B14.

[0049] For example, the depth direction of slot A13 is parallel to the first direction X, the width direction of slot A13 is parallel to the second direction Y, and the length direction of slot A13 is parallel to the third direction Z; the depth direction of slot B14 is parallel to the first direction X, the width direction of slot B14 is parallel to the second direction Y, and the length direction of slot B14 is parallel to the third direction Z; the first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0050] During assembly, the second fixing plate A23 is inserted into the slot A13 along the first direction X. The opposite side walls of the slot A13 in the second direction Y can restrict the movement of the second fixing plate A23 relative to the substrate 1 in the second direction Y. The second fixing plate B24 is inserted into the slot B14 along the first direction X. The opposite side walls of the slot B14 in the second direction Y can restrict the movement of the second fixing plate B24 relative to the substrate 1 in the second direction Y. This facilitates the assembly and positioning of the second fixing plates A23 and B24 with the substrate 1, increases the contact area between the second fixing plates A23 and B24 and the substrate 1, and also facilitates fixing processes such as welding.

[0051] During assembly, the second fixing plate A23 and the second fixing plate B24 can also be inserted into the slots A13 and B14 respectively along the third direction Z.

[0052] Optionally, the substrate 1 is L-shaped. In the first direction X, the length of the first mounting portion 11 is greater than the length of the second mounting portion 12. The first mounting portion 11 has a plurality of mounting holes, which are sequentially opened along the first direction X. The mounting holes are used to insert threaded fasteners.

[0053] For example, the mounting hole in the first mounting portion 11 is designated as the first mounting hole 111, and the mounting hole in the second mounting portion 12 is designated as the second mounting hole 121. The first mounting portion 11 has a relatively large dimension in the first direction X and has multiple first mounting holes 111 along the first direction X, providing multiple mounting positions for the steering device 200 arranged along the first direction X, so that the steering device 200 can be mounted more stably on the substrate 1. The second mounting portion 12 has a relatively small dimension in the first direction X and has only one second mounting hole 121 in the first direction X. In this way, while ensuring stable mounting of the steering device 200 and the substrate 1, the volume of the substrate 1 can be reduced, thereby reducing the weight of the substrate 1.

[0054] Optionally, the fixing plate assembly 2 further includes a third fixing plate 25, which is mounted on the centerline of the base plate 1 in the second direction Y. First fixing plates A21 and B22 are symmetrically arranged on both sides of the third fixing plate 25, and second fixing plates A23 and B24 are symmetrically arranged on both sides of the third fixing plate 25. This arrangement ensures that the support points between the steering device mounting bracket 100 and the bridge tube 300 are symmetrically distributed, avoiding stress concentration.

[0055] Optionally, a third mounting portion 16 is formed between the third fixing plate 25 and the second fixing plate A23, and a fourth mounting portion 17 is formed between the third fixing plate 25 and the second fixing plate B24. The third mounting portion 16 and the fourth mounting portion 17 are each provided with a weight-reducing hole 15. The weight-reducing holes 15 reduce the overall weight of the steering device mounting bracket 100. Furthermore, the weight-reducing holes 15 and the mounting holes are staggered in the first direction X, which avoids the problem of reduced structural strength caused by the concentration of openings in the substrate 1.

[0056] Optionally, the fixing plate is perpendicular to the substrate 1.

[0057] Optionally, the fixing plate is welded to the base plate 1; and / or, the fixing plate is welded to the bridge tube 300. The welding fixing method is relatively simple in process and has high structural strength, which makes the mounting bracket of the steering device 200 have strong stability.

[0058] An unmanned logistics vehicle is also provided, including an axle tube 300, a steering device 200, and the aforementioned steering device mounting bracket 100, wherein the steering device 200 is fixed to the axle tube 300 via the steering device mounting bracket 100.

[0059] For example, the steering device 200 is a DP-EPS (Dual Power Electric Power Steering) system.

[0060] Furthermore, the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the protection scope of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
