It is characterized in that a driving gear for driving the steering gear to rotate is arranged on the vehicle frame and at the side end relative to the steering gear. A driving motor for driving the driving gear to work is connected to the lower end of the driving gear. The driving motor is connected to the lower end of the vehicle frame through a connecting housing. Four fixing rods are fixedly arranged on the connecting housing. Four through holes for the fixing rods to pass through are formed on the vehicle frame. A positioning component for positioning the connecting housing on the vehicle frame is arranged on the four fixing rods. The positioning component is composed of a positioning piece and a return spring. The connecting housing is fixed on the vehicle frame by the positioning piece abutting against the upper end of the vehicle frame.

[0006] In the above-mentioned novel steering module, an installation groove for installing the positioning component is formed on the fixing rod. One end of the positioning piece extends out of the installation groove, and the other end of the positioning piece extends into the installation groove and is connected to the return spring. The positioning piece contracts in the installation groove through the return spring.

[0007] In the above-mentioned novel steering module, a gearbox component is arranged in the connecting housing. A transmission shaft is arranged on the driving gear and is connected to the inside of the gearbox component.

[0008] In the above-mentioned novel steering module, the driving gear meshes with the steering gear.

[0009] Compared with the prior art, in this new steering module, the connection housing is fixedly installed on the vehicle frame through the positioning component. When it is necessary to repair the drive motor, it is convenient for the staff to disassemble it from the vehicle frame to repair and replace the drive motor. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The following are specific embodiments of the present utility model in conjunction with the accompanying drawings to further describe the technical solutions of the present utility model, but the present utility model is not limited to these embodiments.

[0014] As Figure 1 , Figure 2 shown, this new steering module includes a wheel 1 and a vehicle frame 2. A steering gear 3 connected to the wheel 1 and controlling the steering of the wheel 1 is provided on the vehicle frame 2. A driving gear 4 for driving the steering gear 3 to rotate is provided on the vehicle frame 2 and on the side end relative to the steering gear 3. The lower end of the driving gear 4 is connected to a drive motor 5 for driving the driving gear 4 to work. The motor shaft of the drive motor 5 extends into the gearbox, and the driving force is transmitted to the driving gear 4 through the gearbox assembly. The rotation of the driving gear 4 drives the meshing steering gear 3 to rotate. The drive motor 5 is connected to the lower end of the vehicle frame 2 through a connection housing 6. Four fixing rods 7 are fixedly provided on the connection housing 6. The fixing rods 7 and the connection housing 6 are integrally formed and penetrate through the vehicle frame 2 from the lower end of the opening of the vehicle frame 2. Four openings for the fixing rods 7 to penetrate are provided on the vehicle frame 2. A positioning component 8 for positioning the connection housing 6 on the vehicle frame 2 is provided on the four fixing rods 7. The positioning component 8 is composed of a positioning piece 9 and a return spring 10. The connection housing 6 is fixed to the vehicle frame 2 by the positioning piece 9 abutting against the upper end of the vehicle frame 2.

[0015] In further detail, an installation groove for installing the positioning component 8 is provided on the fixing rod 7. One end of the positioning piece 9 extends out of the installation groove, and the other end of the positioning piece 9 extends into the installation groove and is connected to the return spring 10. The return spring 10 enables the positioning piece 9 to contract in the installation groove.

[0016] Specifically, when the drive motor 5 needs to be disassembled, the staff uses a tool to apply pressure to the positioning member 9, the return spring 10 is compressed, the positioning member 9 contracts into the installation groove, and the fixing rod 7 can be removed from the opening of the vehicle frame 2, so as to repair and replace the gearbox assembly of the drive motor 5 and the connecting housing 6. When the drive motor 5 needs to be installed, the staff first uses a tool to apply pressure to the positioning member 9, the return spring 10 is compressed, the positioning member 9 contracts into the installation groove, then the fixing rod 7 is inserted from the opening of the vehicle frame 2 until the positioning assembly 8 is located at the upper end of the vehicle frame 2, the return spring 10 rebounds, and the positioning member 9 contacts the upper end of the vehicle frame 2, thereby fixing the gearbox assembly of the drive motor 5 and the connecting housing 6 to the vehicle frame 2.

[0017] Specifically, a gearbox assembly is provided in the connecting housing 6, and a transmission shaft is provided on the driving gear 4 and is connected to the inside of the gearbox assembly.

[0018] Specifically, the driving gear 4 meshes with the steering gear 3.

[0019] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0020] Although terms such as wheel 1, vehicle frame 2, steering gear 3, driving gear 4, drive motor 5, connecting housing 6, fixing rod 7, positioning assembly 8, positioning member 9, return spring 10, etc. are used more frequently in this article, the possibility of using other terms is not excluded.
