The steering axle is rotatably connected to the frame body. The synchronous steering structure includes a steering drive rod, a synchronous transmission rod, a first steering seat, and a second steering seat.

Description

Technical Field

[0001] This utility model belongs to the field of transportation technology, specifically relating to a steering structure that is easy to assemble and level. Background Technology

[0002] Chinese patent publication number "CN211809956U" discloses an Ackerman steering structure for an inspection AGV (Automated Guided Vehicle), including a base. A motor is mounted on the upper end of the base and connected to the vehicle's power supply via wires. A gear is mounted on the left side of the motor, and a rack is mounted on the lower end of the gear. A connecting block is mounted on the lower end of the rack, and the connecting block is fixedly connected to the rack by bolts. Universal ball joints are mounted on both sides of the connecting block, and the connecting block and the universal ball joints are movably connected via universal ball joints. A crank is mounted at the end of the universal ball joint, and a steering block is fixedly connected to the crank. A wheel is connected to the drive shaft of the steering block.

[0003] The two wheels in the aforementioned patent are driven by two universal ball joints arranged in a figure-eight shape, so that when one wheel turns, the other wheel can be driven to rotate synchronously through the two universal ball joints.

[0004] During assembly, the two swivel joints must be connected sequentially to the steering blocks containing the wheels. After connecting one swivel joint to its corresponding steering block, the worker must connect the other swivel joint while maintaining the parallelism of the two wheels. During this process, the two wheels are prone to misalignment or tilting, resulting in inconsistent swing amplitudes during subsequent steering and potentially causing an accident. Ensuring the two wheels are parallel after installation requires additional tools or single-handed operation, which is inconvenient and reduces assembly efficiency. Utility Model Content

[0005] To overcome the shortcomings of the existing technology, this utility model provides a steering structure that is easy to assemble and level, so as to solve the technical problem of inconvenient assembly of the existing steering mechanism.

[0006] To achieve the above objectives, the specific technical solution of this utility model is as follows: A steering structure that is easy to assemble and level includes a frame body, a steering axle, and a synchronous steering structure. The steering axle is rotatably connected to the frame body.

[0007] The synchronous steering structure includes a steering drive rod, a synchronous transmission rod, a first steering seat, and a second steering seat. The first and second steering seats are rotatably connected to both ends of the vehicle frame body, respectively. The steering drive rod and the synchronous transmission rod are arranged at intervals along the vertical direction.

[0008] The two ends of the steering drive rod are rotatably connected to the bottom of the steering shaft and the first steering seat, respectively; the two ends of the synchronous transmission rod are rotatably connected to the first steering seat and the second steering seat, respectively, forming a double-layer steering transmission structure.

[0009] Furthermore, the steering shaft is divided into an upper main body and a lower transmission part. The inner end of the steering drive rod is rotatably connected to the transmission part.

[0010] Furthermore, the top and bottom of the first steering seat extend outward to form a first transmission bracket and a synchronizing bracket that are parallel to each other. The top of the second steering seat extends outward to form a second transmission bracket. The two ends of the rotation drive rod are rotatably connected to the bottom of the rotation shaft and the synchronizing bracket, respectively. The two ends of the synchronizing transmission rod are rotatably connected to the first transmission bracket and the second transmission bracket, respectively.

[0011] Furthermore, the synchronization bracket and the transmission part of the steering shaft are flush in the height direction. The second transmission bracket is flush in the height direction with the first transmission bracket.

[0012] Furthermore, both ends of the steering drive rod and the synchronous transmission rod are equipped with fisheye bearings.

[0013] Furthermore, the projection of the axis of the steering drive rod and the axis of the synchronous transmission rod onto the horizontal plane coincides.

[0014] Compared with the prior art, the present invention has the following advantages: 1. This utility model uses a steering drive rod and a synchronous transmission rod arranged at intervals along the vertical direction and parallel to each other to achieve synchronous steering of the two wheels. During assembly, while assembling one end of the synchronous transmission rod and then assembling the other end, the balance, i.e., the parallelism, between the two wheels can be adjusted to ensure that the two wheels are parallel to each other when assembled. This avoids inconsistent steering angles of the two wheels when the mobility scooter turns, which would affect the balance performance of the mobility scooter when turning.

[0015] 2. This utility model makes the projections of the steering drive rod axis and the synchronous transmission rod axis on the horizontal plane coincide, so that when the two wheels are subjected to external impact force, the steering drive rod and the synchronous transmission rod can be subjected to force simultaneously and evenly. Compared with the force of a single rod arranged in front and behind, the even distribution of the force points can improve the safety of the steering structure. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, 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.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] like Figure 1 and 2 As shown, a steering structure that is easy to assemble and level includes a frame body 1, a steering axle 2, and a synchronous steering structure 3. The steering axle 2 is rotatably connected to the frame body 1, and its bottom is connected to the middle of the synchronous steering structure 3, used to drive the synchronous steering structure 3 to move left and right. The two ends of the synchronous steering structure 3 are respectively connected to two wheels, enabling the two wheels to steer synchronously during left and right movement, thereby ensuring the synchronicity of the two wheels during adjustment.

[0021] like Figure 2 As shown, the synchronous steering structure 3 includes a steering drive rod 4, a synchronous transmission rod 5, a first steering seat 6, and a second steering seat 7. The first steering seat 6 and the second steering seat 7 are rotatably connected to both ends of the vehicle frame body 1, respectively. The steering drive rod 4 and the synchronous transmission rod 5 are arranged at intervals along the vertical direction. The two ends of the steering drive rod 4 are rotatably connected to the steering shaft 2 and the first steering seat 6, respectively; the two ends of the synchronous transmission rod 5 are rotatably connected to the first steering seat 6 and the second steering seat 7, respectively, forming a double-layer steering transmission structure.

[0022] When performing a steering operation, the user rotates the steering shaft 2, which in turn causes the steering drive lever 4 to swing horizontally to the left or right. The first steering seat 6 rotates under the push of the steering drive lever 4, and pulls the synchronous transmission rod 5 to swing horizontally in the same synchronous manner as the steering drive lever 4, which in turn causes the second steering seat 7 to rotate, thereby realizing synchronous steering of the two wheels mounted on the first steering seat 6 and the second steering seat 7.

[0023] Furthermore, such as Figure 2 and 3 As shown, the top and bottom of the first steering seat 6 extend outward to form a first transmission bracket 8 and a synchronous bracket 9 that are parallel to each other. The synchronous bracket 9 is flush with the bottom of the steering shaft 2 in the height direction. The top of the second steering seat 7 extends outward to form a second transmission bracket 10. The second transmission bracket 10 is flush with the first transmission bracket 8 in the height direction. Both ends of the rotation drive rod are rotatably connected to the bottom of the rotation shaft and the synchronous bracket 9, respectively. Both ends of the synchronous transmission rod 5 are rotatably connected to the first transmission bracket 8 and the second transmission bracket 10, respectively.

[0024] In this embodiment, both the steering drive rod 4 and the synchronous transmission rod 5 employ balance bars. Both ends of the steering drive rod 4 and the synchronous transmission rod 5 are equipped with spherical bearings. The spherical bearings, in conjunction with bolts and nuts, enable the rotational connection between the steering drive rod, the synchronous transmission rod, and the first and second bearing seats. Specifically, both the first and second bearing seats have mounting holes. Bolts pass through the mounting holes and the corresponding spherical bearings in sequence, and the nuts define their positions, thereby completing the rotational connection between the ends of the steering drive rod 4 and the synchronous transmission rod 5 and the first and second bearing seats.

[0025] Furthermore, the projections of the axis of the steering drive rod 4 and the axis of the synchronous transmission rod 5 on the horizontal plane coincide, so that when the two wheels are subjected to external impact force, the steering drive rod 4 and the synchronous transmission rod 5 can be subjected to force simultaneously and evenly. Compared with the force of a single rod arranged in front and behind, the even distribution of the force points can improve the safety of the steering structure.

[0026] like Figure 4 As shown, in this embodiment, the steering shaft 2 is divided into an upper main body 11 and a lower transmission part 12. The inner end of the steering drive rod 4 is rotatably connected to the transmission part 12.

[0027] The assembly and working principle of this utility model are as follows: During assembly, workers sequentially assemble both ends of the synchronous transmission rod 5 with the first steering seat 6 and the second steering seat 7. Simultaneously, while assembling one end of the synchronous transmission rod 5 and then proceeding with the assembly of the other end, the balance, or parallelism, between the two wheels can be adjusted. This ensures that the two wheels are parallel to each other upon completion, preventing inconsistent steering angles between the two wheels during subsequent turns and ensuring the vehicle's balance during cornering.

[0028] Secondly, after the installation of the synchronous transmission rod 5 is completed, the workers can free their hands to complete the assembly between the steering drive rod 4, the steering shaft 2, and the first bearing seat. During the assembly process, the balance between the two wheels is maintained by the synchronous transmission rod 5, effectively preventing the relative position between the two wheels from shifting during the installation of the steering drive rod 4, which would affect subsequent use.

[0029] During use, when steering, the user rotates the steering shaft 2, which in turn causes the steering drive lever 4 to swing horizontally to the left or right. The first steering seat 6 rotates under the push of the steering drive lever 4, and pulls the synchronous transmission rod 5 to swing horizontally in the same synchronous manner as the steering drive lever 4, which in turn causes the second steering seat 7 to rotate, thereby achieving synchronous steering of the two wheels mounted on the first steering seat 6 and the second steering seat 7.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the 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 or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
