[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0035] Embodiment 1

[0036] like Figure 1 - Figure 4 As shown, this embodiment discloses an automatic driving steering gear assembly and a frame, including a column mounting beam 1, a manipulator 2 is arranged on the upper part of the column mounting beam 1, a steering component 3 is arranged on one side of the manipulator 2, a transmission shaft 4 connected through a universal joint is arranged on the upper part of the steering component 3, a rotating column 5 connected through a universal joint is arranged on the upper part of the transmission shaft 4, a multi-tooth groove 51 is arranged in the middle part of the outer surface of the rotating column 5, a driving device 6 is arranged on the lower part of the outer surface of the rotating column 5, and a steering wheel 8 is arranged on the upper end of the rotating column 5.

[0037] Specifically, when the driver turns, the steering wheel 8 can be turned to drive the rotating column 5 to rotate, and then the rotating column 5 drives the transmission shaft 4 to rotate through the universal joint, and the transmission shaft 4 drives the steering component 3 to rotate through the universal joint, and then the steering component 3 drives the manipulator 2 to rotate, so that the manipulator 2 drives the wheels on both sides to rotate.

[0038] During the automatic driving process, the driver will not provide power, so the drive device 6 is required to provide kinetic energy to drive the rotating column 5 to rotate in order to achieve the corresponding steering action. In this process, the corresponding control unit is required to give the drive device 6 an output signal so that the drive device 6 can drive the rotating column 5 to rotate. This is all existing technology and will not be described in detail in this specification.

[0039] In order to provide the power for turning the rotating column 5 and facilitate the installation of the driving device 6 by the staff, Figure 4 As shown, the driving device 6 includes a driving motor 61, a quick mounting part 63 is provided at the lower part of the outer surface of the driving motor 61, and a mounting ring 62 is provided on the side of the outer surface of the quick mounting part 63 away from the driving motor 61. The mounting ring 62 is fixedly installed at the lower part of the outer surface of the rotating column 5.

[0040] Further, such as Figure 5 and Figure 6 As shown, the quick installation part 63 includes a U-shaped frame 631, which is fixedly installed on the outer surface of the mounting ring 62. Limiting holes 632 are provided on both sides of the outer surface of the U-shaped frame 631. A mounting block 633 is provided in the middle of the U-shaped frame 631. Three pairs of positioning blocks 634 are provided in the middle of the mounting block 633. Springs are provided at the ends of the three pairs of positioning blocks 634 close to each other. E-shaped rods 635 are provided on both sides of the outer surfaces of the three pairs of positioning blocks 634. The two E-shaped rods 635 are adapted for use with the limiting holes 632.

[0041] Specifically, when installing the drive motor 61, the staff can press the E-shaped rods 635 on both sides so that the E-shaped rods 635 on both sides squeeze the three pairs of positioning blocks 634, so that the springs in the middle of the three pairs of positioning blocks 634 are compressed, and then the staff can put the mounting block 633 into the inner cavity of the U-shaped frame 631. During this process, the E-shaped rod 635 will slide in the inner cavity of the limiting hole 632. After the mounting block 633 is placed in the corresponding position, the E-shaped rods 635 on both sides are released so that the three pairs of positioning blocks 634 are stuck on the inner wall of the U-shaped frame 631. Since the mounting block 633 is fixedly connected to the drive motor 61, the installation of the drive motor 61 is completed.

[0042] Furthermore, before performing the above-mentioned actions, the staff needs to fix the mounting ring 62 on the lower portion of the outer surface of the multi-tooth slot 51 .

[0043] Embodiment 2

[0044] This embodiment further improves the transmission device 7 on the basis of the first embodiment, such as Figure 1 - Figure 3 As shown, the output end of the driving device 6 is provided with a transmission device 7 for transmitting power to the rotating pipe column 5 .

[0045] In order to transmit the power output by the driving motor 61 to the rotating column 5 for steering, and at the same time, it is convenient for the staff to install the transmission device 7, such as Figure 7 As shown, the transmission device 7 includes a mounting shell 71, which is fixedly mounted on the upper part of the driving motor 61, a gear 72 is rotatably mounted on the side of the inner cavity of the mounting shell 71 away from the rotating column 5, the middle part of the gear 72 is fixedly connected to the output end of the driving motor 61, a transmission mechanism 1 73 is arranged on the side of the inner cavity of the mounting shell 71 close to the rotating column 5, a transmission mechanism 2 74 is arranged on the outer surface of the mounting shell 71, an energy storage device 75 is arranged in the middle of the outer surface of the mounting shell 71, and observation holes 711 are opened on both sides of the connection between the mounting shell 71 and the transmission mechanism 2 74.

[0046] Specifically, during the automatic driving process, when steering is required, the corresponding control unit outputs a signal to control the drive motor 61 to rotate. At this time, the kinetic energy output by the drive motor 61 is transmitted to the transmission mechanism 1 73 and the transmission mechanism 2 74 through the gear 1 72. Then, the transmission mechanism 1 73 and the transmission mechanism 2 74 drive the rotating column 5 to rotate. The transmission mechanism 1 73 and the transmission mechanism 2 74 can form a complete gear, so it will not hinder the gear 1 72 from driving the transmission mechanism 1 73 and the transmission mechanism 2 74 to rotate.

[0047] Furthermore, during the installation of the transmission device 7, the staff first removes the transmission mechanism 2 74 from one side of the mounting shell 71. At this time, the transmission mechanism 1 73 and the transmission mechanism 2 74 are separated, and then the inner surface of the transmission mechanism 1 73 is fitted on the multi-tooth slot 51, and then the transmission mechanism 2 74 is re-attached to the mounting shell 71. This method makes it easier for the staff to install the transmission device 7.

[0048] Furthermore, since the mounting shell 71 and the drive motor 61 are fixedly connected, the staff needs to remove the transmission mechanism 2 74 before installing the drive motor 61. When the staff installs the drive motor 61, the transmission mechanism 1 73 is also installed to the corresponding position, and then the transmission mechanism 2 74 is reconnected to the mounting shell 71. During this process, the mounting ring 62 can play a positioning role, so that the semicircular transmission retaining ring on the inner surface of the transmission mechanism 1 73 can be in close contact with the multi-tooth groove 51, avoiding a large difference in the installation position, which affects the transmission effect of the drive motor 61 on the rotating pipe column 5 through the transmission device 7.

[0049] The transmission mechanism 1 73 and the transmission mechanism 2 74 cooperate to transmit the power output by the driving motor 61 to the rotating column 5. At the same time, in order to facilitate the staff, the transmission device 7 is installed on the outer surface of the rotating column 5, such as Figure 8 - Fig.10As shown, the transmission mechanism 2 74 includes a semicircular frame 741, which is connected to the mounting shell 71 by a buckle, a semicircular gear 3 742 is slidably installed in the middle of the inner cavity of the semicircular frame 741, a brake member 743 is provided on the lower middle side of the semicircular gear 3 742, and limiting rods 2 745 are provided on both sides of the brake member 743, and the limiting rods 2 745 are slidably installed in the inner wall of the semicircular gear 3 742, and a spring is provided for the connection between the limiting rod 2 745 and the semicircular gear 3 742, and the lower ends of the two limiting rods 2 745 are provided with conical rubber blocks 7451, and the upper part of the semicircular frame 741 is provided with a pushing member 744, and the pushing member 744 is adapted for use with the brake member 743 and the two pushing members 744, and limiting rings 746 are provided on both sides of the lower end of the semicircular frame 741, and the two limiting rings 746 are adapted for use with the conical rubber blocks 7451 in the two limiting rods 2 745 respectively.

[0050] Further, such as Fig.12 As shown, the brake member 743 includes a hydraulic frame 7431, which is fixedly installed in the inner wall of the lower middle part of the semicircular gear three 742. A piston 7432 is arranged in the middle of the inner cavity of the hydraulic frame 7431, and brake rods 7433 are arranged on both sides of the upper end of the piston 7432. The upper ends of the two brake rods 7433 extend to the outside of the semicircular gear three 742, and the two brake rods 7433 are adapted for use with the push member 744.

[0051] Further, such as Fig.11 and Fig.13 As shown, the transmission mechanism 73 includes a semicircular gear 4 731, which is slidably installed in the inner cavity of the mounting shell 71. Mounting holes are provided on the end faces of both sides of the semicircular gear 731, and a plurality of elastic limit members 732 are provided on the outer sides of the two mounting holes. A fixing mechanism 733 is provided in the middle of the inner cavity of the two mounting holes. One end of the two fixing mechanisms 733 close to the brake member 743 extends to the outside of the semicircular gear 4 731, and the inner cavities of the two fixing mechanisms 733 are connected to the upper inner cavity of the hydraulic frame 7431 through hydraulic pipes.

[0052] Furthermore, the inner surfaces of the semicircular gear four 731 and the semicircular gear three 742 are both provided with semicircular transmission clamping rings adapted for use with the multi-tooth clamping groove 51.

[0053] Further, such as Fig.12 and Fig.14As shown, the fixing mechanism 733 includes a mounting cylinder 7331, which is fixedly mounted in the middle of the inner cavity of the mounting hole, and an array of positioning blocks 7333 is arranged on the outer surface of the mounting cylinder 7331, and multiple positioning blocks 7333 are matched with multiple elastic limiting members 732. A hydraulic push rod 7332 is arranged on one side of the inner cavity of the mounting cylinder 7331, and the end face of the hydraulic push rod 7332 extends to the outside of the mounting cylinder 7331, and the inner cavity of the hydraulic push rod 7332 is communicated with the upper part of the inner cavity of the hydraulic frame 7431 through a hydraulic pipe, and a limiting rod 7335 is arranged at the protruding end of the hydraulic push rod 7332, and multiple annular limiting grooves 7334 are opened on the outer surface of the limiting rod 7335, and the multiple annular limiting grooves 7334 are respectively matched with multiple positioning blocks 7333.

[0054] Specifically, before installing the transmission device 7 on the outer surface of the rotating pipe column 5, the staff can first press the pushing member 744 so that the pushing member 744 drives the brake member 743 and the limiting rods 745 on both sides to move downward. During this process, the conical rubber blocks 7451 at the lower parts of the limiting rods 745 on both sides will pass through the limiting rings 746, and the limiting rods 745 will be stuck through the cooperation of the conical rubber blocks 7451 and the limiting rings 746, so that the semicircular gear three 742 is also restricted from sliding in the inner cavity of the semicircular frame 741. At the same time, when the pushing member 744 pushes the brake rods 7433 on both sides to move downward, the brake rods 7433 on both sides will push the piston 7432 to move downward. During this process, the brake member 743 sucks the hydraulic oil in the inner cavity of the hydraulic push rods 7332 on both sides into its inner cavity. At this time, the hydraulic push rods 7332 contract and drive the limiting rod 1 7335 to move.

[0055] Furthermore, when the limit rod 1 7335 moves, the inner cavity surface of the annular limit groove 7334 on the limit rod 1 7335 will contact the multiple positioning blocks 2 7333, so that the multiple positioning blocks 2 7333 are disengaged from the inner cavity of the elastic limit member 732 under the push of the multiple elastic limit members 732, and then the positioning blocks 2 7333 enter the inner cavity of the annular limit groove 7334. At this time, the staff can pull the semicircular frame 741 to the side away from the driving device 6, so that the fixing mechanism 733 is pulled out from the installation cavity on the semicircular gear four 731, thereby releasing the fixing relationship between the semicircular gear four 731 and the semicircular gear three 742.

[0056] Furthermore, when the staff installs the driving device 6 to the corresponding position, the transmission mechanism 1 73 is also installed to the corresponding position. At this time, the fixing mechanism 733 can be inserted into the mounting holes on both sides of the semicircular gear 4 731 again, and then the pushing piece 744 is released. At this time, the piston 7432 moves upward under the action of multiple springs, and the hydraulic oil on the upper part of the hydraulic frame 7431 is squeezed into the inner cavity of the two hydraulic push rods 7332 again, so that the hydraulic push rod 7332 pushes the limit rod 1 7335 to move. In this process, the multiple positioning blocks 2 7333 can be pushed outward again through the inclined surface on the inner side of the annular limit groove 7334, so that the multiple positioning blocks 2 7333 can enter the inner cavity of the multiple elastic limit members 732 again. At this time, the springs inside the multiple elastic limit members 732 are squeezed by force. At this time, the semicircular gear 4 731 and the semicircular gear 3 742 form a complete gear again.

[0057] Furthermore, after the semicircular gear four 731 and the semicircular gear three 742 are fixed together, since the conical rubber block 7451 is made of rubber, the staff can push the conical rubber block 7451 upward so that the limiting ring 746 no longer blocks the limiting rod two 745. At this time, the gear composed of the semicircular gear four 731 and the semicircular gear three 742 can rotate in the inner cavity of the mounting shell 71 and the semicircular frame 741, so that the gear one 72 can drive the rotating column 5 to rotate through the gear composed of the semicircular gear four 731 and the semicircular gear three 742.

[0058] Embodiment 3

[0059] This embodiment further improves the energy storage device 75 based on the first embodiment, such as Figure 7 As shown, the energy storage device 75 includes a second gear 751, which is rotatably installed in the inner cavity of the mounting shell 71. The upper and lower ends of the second gear 751 extend to the outside of the mounting shell 71. A knob 752 is provided on the upper part of the second gear 751, and a small generator 753 is fixedly installed on the lower end of the mounting shell 71 at the lower end of the second gear 751.

[0060] Furthermore, gear two 751 is adapted for use with semicircular gear four 731 and semicircular gear three 742 .

[0061] Specifically, during the automatic driving process, when the drive motor 61 drives the semicircular gear four 731 and the semicircular gear three 742 to rotate through the gear one 72, the gear composed of the semicircular gear four 731 and the semicircular gear three 742 will also drive the knob 752 to rotate, so that the knob 752 drives the small generator 753 to operate, and then the steering kinetic energy of the vehicle is converted into electrical energy and stored through the small generator 753, which is used to provide part or all of the energy for the drive motor 61 of the steering gear assembly, thereby improving energy utilization efficiency and reducing the energy consumption of the vehicle.

[0062] Furthermore, when the transmission device 7 needs to be installed or disassembled, at this time, the semicircular gear four 731 and the semicircular gear three 742 may not be in the corresponding disassembly position. At this time, the staff can turn the knob 752 to adjust the position of the semicircular gear four 731 and the semicircular gear three 742, and then observe through the observation hole 711 on the upper part of the mounting shell 71 whether the position of the semicircular gear four 731 and the semicircular gear three 742 has reached the corresponding disassembly position.

[0063] It should be noted that the specific installation method, circuit arrangement and connection method, and control method of the drive motor 61 used in the above-mentioned embodiment 1 are conventional designs in the prior art and will not be elaborated in detail in the present invention.

[0064] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
