Description

Technical Field

[0001] This utility model relates to the technical field of motorcycles, and in particular to a frame steering structure. Background Technology

[0002] In existing technologies, steering rods are mostly fixed to the outside of the vehicle frame at a single point, lacking circumferential protection. This makes them susceptible to structural failure due to impacts in off-road or complex road conditions. This invention solves this problem by using the vehicle frame cavity as a protective channel.

[0003] Meanwhile, in existing designs, the steering rod is only fixed by a single upper sleeve, lacking support at the lower end, which easily leads to vibration during high-speed steering. This invention improves stability by adding a support frame and sleeve to form a double fulcrum.

[0004] Traditional steering rods require threaded fasteners to connect to the vehicle frame, and disassembly and assembly require special tools. This invention utilizes a stepped snap-fit ​​design for the connecting rod to achieve tool-free quick disassembly, reducing maintenance costs.

[0005] Some vehicle models lack steering angle limits, and user error could lead to oversteering and rollover. This invention uses a stop-and-top block mechanical limiter to forcibly constrain the rotation range and eliminate the safety risk. Utility Model Content

[0006] Purpose of the invention: The purpose of this utility model is to provide a vehicle frame steering structure that solves the problems of poor rotation performance and poor connection protection of the vehicle frame bogie.

[0007] Technical solution:

[0008] A vehicle frame steering structure includes a frame, a sleeve fixedly connected to the top of the frame, a support frame connected to the lower side of the sleeve, a steering rod detachably connected between the support frame and the sleeve, a handle connected to the end of the steering rod near the sleeve, and a limit structure connected to the end of the steering rod near the support frame.

[0009] Preferably, a connecting ring is fixedly provided on the support frame, and a connecting rod is connected to one end of the steering rod near the connecting ring. The connecting rod is detachably connected to both the steering rod and the connecting ring.

[0010] Preferably, the connecting rod has a stepped groove on its peripheral wall, and the outer diameter of the connecting rod is larger than the inner diameter of the connecting ring.

[0011] Preferably, the limiting structure includes a stop block, which is connected to the connecting rod.

[0012] Preferably, a top block is fixedly connected to the support frame, and the stop block is provided with a guide groove that runs through the steering rod on the side facing the top block, with the top block extending into the guide groove.

[0013] In this embodiment, a mechanical limit is formed by the cooperation of the stop block and the guide groove of the top block. When the steering rod rotates to its limit angle, the top block abuts against the side wall of the guide groove, forcibly stopping the rotation and avoiding vehicle imbalance caused by oversteering. The limiting structure is integrated inside the support frame, saving space and ensuring high reliability.

[0014] Preferably, a connecting rod is connected between the sleeve and the frame, and the connecting rod and the sleeve are fixedly connected.

[0015] Preferably, the frame has a cavity at its center, through which the steering rod passes.

[0016] Preferably, the steering rod is tilted.

[0017] Beneficial effects: The steering rod passes through the multi-tube cavity of the frame, providing circumferential protection and significantly reducing the risk of deformation or breakage due to collisions or bumps during riding. The sleeve, connected to the frame by double connecting rods, forms a triangular stability structure, and welding further enhances torsional strength. The sleeve and support frame are located at opposite ends of the steering rod's axial direction, forming a "dual-pivot" support system. The stepped diameter reduction design of the connecting rod allows for quick engagement with the connecting ring, enabling steering rod assembly and disassembly without additional fasteners.

[0023] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1

[0025] like Figure 1 As shown, a vehicle frame steering structure includes a frame 10, which is a multi-tube structure and has a cavity 11 with multiple holes inside.

[0026] A steering rod 12 is connected to the frame 10. The steering rod 12 is a transmission component. A handle 13 is connected to the upper end of the steering rod 12. The steering rod 12 is rotated by controlling the handle 13.

[0027] To facilitate the operation of the steering rod 12, the axis of the steering rod 12 is angled with the longitudinal centerline of the frame 10, so that the steering rod 12 naturally tilts forward after being installed.

[0028] The steering rod 12 is installed through the internal cavity 11 of the frame 10. The frame 10 reinforces and protects the steering rod 12, reducing the possibility of the steering rod 12 being damaged by impact.

[0029] like Figure 2 As shown, a sleeve 14 is installed on the upper end of the frame 10, and a connecting rod 15 is connected to the outer wall of the sleeve 14. The connecting rod 15 is welded to the sleeve 14 and the frame 10. To ensure the connection strength, at least two connecting rods 15 are provided. The two connecting rods 15 and the frame 10 form a triangular structure. The sleeve 14 is located at the end point where the two connecting rods 15 are connected, which improves the connection effect.

[0030] The steering rod 12 is inserted into the sleeve 14, and the steering rod 12 can rotate around its own axis at the sleeve 14 to achieve angle adjustment.

[0031] like Figure 3 , 4 As shown, a support frame 16 is also connected to the chassis 10, welded to the lower side of the chassis 10, and coaxially corresponding to the sleeve 14. The support frame 16 is similar in structure to the connecting rod 15. The support frame 16 includes two side plates, both of which are fixedly connected to the chassis 10. A connecting ring 17 is fixedly connected to the end of the support frame 16 where the two side plates abut. The support frame 16 is connected to the steering rod 12 through the connecting ring 17.

[0032] The support frame 16 and the connecting rod 15 are located on opposite sides of the axial direction of the steering rod 12, which can provide better support for the steering rod 12.

[0033] The connecting ring 17 and the steering rod 12 are detachably connected. The end of the steering rod 12 is inserted into the connecting ring 17 with a connecting rod 18. The connecting rod 18 is connected to the connecting ring 17, which facilitates the installation and separation of the steering rod 12.

[0034] The connecting rod 18 has several steps on its circumference, and the outer diameter of the connecting rod 18 is reduced towards the end away from the steering rod 12. The inner diameter of the connecting ring 17 is smaller than the outer diameter of the steering rod 12 and the connecting rod 18, thereby achieving the effect of snap-fit ​​support and fixing the steering rod 12.

[0035] The connecting ring 17 can be fitted with a bearing to facilitate the rotation of the steering rod 12.

[0036] The bearing is built into the connecting ring, which reduces rotational friction and lowers the frequency of maintenance.

[0037] Furthermore, a limiting structure is connected to the connecting rod 18, and the rotation angle is controlled by the limiting structure.

[0038] The limiting structure includes a stop 19, which is fixedly connected to the connecting rod 18. The stop 19 is located between the connecting ring 17 and the steering rod 12.

[0039] Furthermore, a top block 20 is connected to the support frame 16, and a guide groove 21 is provided on the side of the stop block 19 facing the top block 20. The guide groove 21 extends axially and its opening faces the top block 20. The upper end of the top block 20 extends into the guide groove 21. When the steering rod 12 rotates, the connecting rod 18 and the stop block 19 rotate accordingly. The top block 20 abuts against the side wall of the guide groove 21 to achieve the function of limiting the steering rod 12.

[0040] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
