Description

Technical Field

[0001] This utility model belongs to the field of tricycle technology, specifically relating to a tricycle steering handle mounting device. Background Technology

[0002] Currently, the front shock absorber assemblies for three-wheeled motorcycles and electric tricycles mainly fall into two categories. One is the double-plate front shock absorber, whose main structure is as follows: a steering shaft passes through the steering tube of the tricycle frame, and the steering shaft is connected to bearings at both ends of the steering tube, allowing for rotational connection between the steering shaft and the steering tube. A lower plate is fixed to the lower end of the steering shaft, and an upper plate is fitted onto the upper end of the steering shaft near the upper surface of the steering tube. The upper plate is secured to the steering shaft by a nut at the upper end of the steering shaft. A steering handle fixing slot is located on the upper surface of the upper plate near the front of the steering shaft, and the steering handle is fixed to the upper plate with bolts. Shock absorber rod mounting holes are located on the front sides of both the lower and upper plates. The upper ends of the shock absorber rods of the two shock absorbers pass through the rod mounting holes of the upper and lower plates, respectively, and are secured with bolts. This constitutes the double-plate front shock absorber assembly and its steering connection to the frame.

[0003] Another type is the single-plate front shock absorber. Its main structure consists of a high-strength steering shaft, which has higher strength than the double-plate structure, passing through the steering tube of the frame. The upper end of the steering shaft is fitted with a steering handlebar connector and fastened to the high-strength steering shaft with a nut. The lower end of the high-strength steering shaft is fixed with a high-strength lower plate, which also has higher strength than the double-plate structure. Shock absorber rod mounting holes are provided on both sides of the front of the high-strength lower plate. The upper ends of the shock absorber rods of the two shock absorbers pass through the rod mounting holes of the high-strength lower plate and are fastened with bolts. This constitutes the single-plate front shock absorber assembly and its steering connection to the frame.

[0004] The advantages, disadvantages, and applications of the two types of front shock absorbers are as follows: The double-leaf front shock absorber has a longer damping rod, resulting in a longer damping stroke, better damping performance, and lower cost. Its disadvantage is that the two damping rods, upper plate, and steering handle occupy too much space when stationary and turning, making it unsuitable for vehicles with dashboard interiors and cabs with or without enclosed cabs. The single-leaf front shock absorber, on the other hand, is suitable for vehicles with dashboard interiors and cabs with or without enclosed cabs. Its disadvantage is that the shorter damping rod results in a shorter damping stroke, leading to poorer damping performance, lower comfort, and generally higher cost. Summary of the Invention

[0005] This utility model addresses the problems of existing double-plate front shock absorption structures for tricycles, where the two shock absorber rods, upper plate, and steering handle occupy too much space when stationary or turning, making them unsuitable for models with dashboard interiors and driver's cabs or semi-enclosed cabs. Single-plate shock absorption structures, on the other hand, suffer from poor shock absorption and ride comfort due to their shorter shock absorber rods and shorter shock absorption stroke. The invention provides a tricycle steering handle mounting device that separates the steering handle fixing clip from the upper plate by setting a mounting shaft, thus freeing up space for dashboard interior installation. Simultaneously, a support mechanism ensures support for the steering handle.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A tricycle steering handle mounting device includes a steering tube fixedly connected to the frame, a steering shaft passing through the steering tube, a lower end of the steering shaft extending out of the steering tube and fixedly connected to a lower connecting plate, and an upper end extending out of the steering tube and fixedly connected to an upper connecting plate. Shock absorber rods corresponding to the two shock absorbers of the tricycle's front wheel are respectively fixedly sleeved on the lower and upper connecting plates. The steering shaft extends upwards out of the upper connecting plate and is fixedly connected to a mounting shaft. The upper end of the mounting shaft is connected to a steering handle mounting clip, and the steering handle mounting clip is connected to a steering handle. There is a gap between the steering handle mounting clip and the upper connecting plate. A support mechanism is provided on the mounting shaft to support the steering handle mounting clip. A dashboard upper panel is provided between the steering handle mounting clip and the upper connecting plate. By setting the mounting shaft, the steering handle is raised to meet the space required for the installation of dashboard interior trim, etc.

[0008] Preferably, the upper end of the mounting shaft is connected to the steering handle plate, the steering handle plate is fixedly connected to the steering handle fixing clip, and an instrument panel top panel is provided between the steering handle plate and the upper plate. The steering handle plate ensures the coaxial rotatable connection between the steering handle fixing clip and the upper plate.

[0009] Preferably, the support mechanism includes a support sleeve fitted on the mounting shaft. The support sleeve is fixedly disposed between the steering handle connecting plate and the upper connecting plate. The support sleeve supports the steering handle connecting plate to prevent the steering handle from moving downward, and at the same time realizes the torque transmission between the steering handle and the shock absorber when steering.

[0010] Preferably, the support mechanism includes an extension shaft, the upper end of which is fixedly connected to the mounting shaft. The diameter of the extension shaft is smaller than that of the mounting shaft. The steering handle plate is sleeved on the extension shaft and keyed to it. The mounting shaft supports the steering handle plate and cooperates with the extension shaft to transmit torque to the steering shaft.

[0011] Preferably, the upper end of the mounting shaft extends out of the steering handlebar connecting plate and is threadedly connected to a cover. The cover is placed on the upper end of the mounting shaft to fix the steering handlebar connecting plate and to protect the upper end of the mounting shaft.

[0012] The beneficial effects of this utility model through the above technical solution are as follows:

[0013] 1. This utility model has a mounting shaft that is fixedly connected after the upper connecting plate extends from the upper end of the steering shaft, which realizes the setting of the instrument panel installation space, avoids interference between the upper connecting plate and the shock absorber rod when the steering handle is turned, and ensures that the steering handle can be turned smoothly after the instrument panel interior is installed, which is conducive to the installation of the instrument panel interior and the cab of the tricycle.

[0014] 2. This utility model uses a mounting shaft and a support sleeve to transmit torque when the steering handle is turned, and supports the steering handle plate, thereby extending the service life of the mounting shaft and the steering shaft. In this way, while ensuring the shock absorption effect, it does not affect the installation of the tricycle's dashboard interior and cab.

[0015] 3. By setting up the mounting shaft and the extension shaft, this utility model can, on the one hand, limit the up and down movement of the steering handlebar connecting plate while realizing the installation of the dashboard interior, and on the other hand, make minimal structural changes to the existing front shock absorber assembly of the tricycle, which is conducive to modification.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0022] like Figures 1-4As shown, this embodiment provides a tricycle steering handlebar mounting device, including a steering tube 2 fixedly connected to the frame 1. A steering shaft 3 passes through the steering tube 2. The lower end of the steering shaft 3 extends out of the steering tube 2 and is fixedly connected to a lower connecting plate 4, and the upper end extends out of the steering tube 2 and is fixedly connected to an upper connecting plate 5. The shock absorber rods 6 corresponding to the two shock absorbers of the tricycle's front wheel are respectively fixedly sleeved on both ends of the lower connecting plate 4 and the upper connecting plate 5. The steering shaft 3 extends upward out of the upper connecting plate 5 and is fixedly connected to a mounting shaft 7. The steering shaft 3 and the mounting shaft 7 are integrally formed. The upper end of the mounting shaft 7 is connected to a steering handlebar fixing clip 8, and the steering handlebar fixing clip 8 is connected to a steering handlebar 9. Figure 4 As shown, the steering handle fixing clip 8 includes an upper clip and a lower clip. The middle part of the steering handle 9 is located between the upper clip and the lower clip. The upper clip and the lower clip are fastened together by bolts, so that when the steering handle 9 is turned, it drives the steering handle fixing clip 8 to rotate.

[0023] There is a gap between the steering handle fixing clip 8 and the upper connecting plate 5. A support mechanism is provided on the mounting shaft 7. The support mechanism is used to support the steering handle fixing clip 8. The instrument panel top panel 10 is provided between the steering handle fixing clip 8 and the upper connecting plate 5. Specifically, the mounting shaft 7 passes through the instrument panel top panel 10.

[0024] The upper end of the mounting shaft 7 is connected to the steering handle plate 11, the steering handle plate 11 is fixedly connected to the steering handle fixing clip 8, and the instrument panel top panel 10 is provided between the steering handle plate 11 and the upper connecting plate 5. The setting of the mounting shaft 7 makes it possible for there to be an instrument panel mounting space between the steering handle fixing clip 8 and the upper connecting plate 5.

[0025] As one possible implementation, the steering handle plate 11 and the steering handle fixing clip 8 are integrally formed. Specifically, the steering handle plate 11 and the lower clip of the steering handle fixing clip 8 are integrally formed, and the upper clip and the lower clip of the steering handle fixing clip 8 are connected by bolts.

[0026] A cover 14 is provided on the upper end of the mounting shaft 7 above the steering handle plate 11. The cover 14 covers the upper end of the mounting shaft 7. The inner side of the cover 14 and the outer side of the upper end of the mounting shaft 7 are respectively provided with threads. The mounting shaft 7 and the cover 14 are connected by threads, which fixes the steering handle plate 11. The cover 14 is provided to limit the steering handle plate 11 on the one hand, and to prevent rainwater from contacting the mounting shaft 7 on the other hand.

[0027] like Figure 1As shown, the support mechanism includes a support sleeve 12 sleeved on the mounting shaft 7. The support sleeve 12 is fixedly disposed between the steering handle connecting plate 11 and the upper connecting plate 5. When the steering handle fixing clip 8 rotates, the steering handle connecting plate 11 drives the support sleeve 12 to rotate, which in turn drives the upper connecting plate 5 and the shock absorber rod 6 to rotate, thereby realizing the steering of the tricycle. At the same time, the mounting shaft 7 and the steering shaft 3 rotate, and the torque is transmitted through the support sleeve 12. There is no need for torque transmission between the mounting shaft 7 and the steering shaft 3, which reduces the strength requirements of the mounting shaft 7 and the steering shaft 3 and extends the service life of the mounting shaft 7 and the steering shaft 3.

[0028] In one possible implementation, the steering handlebar connecting plate 11 and the support sleeve 12 are connected by multiple circumferentially arranged positioning pins to achieve synchronous rotation. Specifically, the upper side of the support sleeve 12 has multiple circumferentially arranged lower grooves, and the lower side of the steering handlebar connecting plate 11 has multiple upper grooves corresponding to the lower grooves. The two ends of the multiple positioning pins are respectively located in the corresponding upper and lower grooves. The lower side of the support sleeve 12 and the upper connecting plate 5 are connected by multiple circumferentially arranged positioning pins to achieve synchronous rotation. The positioning pin setting method is the same as the connection method between the upper end of the support sleeve 12 and the steering handlebar connecting plate 11. At the same time, the buckle cover 14 ensures the axial limiting and fixing of the steering handlebar connecting plate 11 and the support sleeve 12, that is, the tight installation along the axial direction of the mounting shaft 7, so that the steering handlebar connecting plate 11 and the support sleeve 12 can be easily disassembled and assembled.

[0029] As one possible implementation, the support sleeve 12 and the steering handle plate 11 are integrally formed.

[0030] The support mechanism includes an extension shaft 13. The upper end of the mounting shaft 7 is fixedly connected to the extension shaft 13. The extension shaft 13 and the mounting shaft 7 are integrally formed. The diameter of the extension shaft 13 is smaller than that of the mounting shaft 7. The steering handle connecting plate 11 is sleeved on the extension shaft 13 and is connected to the extension shaft 13 with a key. When the steering handle fixing clip 8 rotates, the steering handle connecting plate 11 drives the extension shaft 13 to rotate, which in turn drives the steering shaft 3 to rotate. Since the steering shaft 3 is fixedly connected to the lower connecting plate 4, the lower connecting plate 4 and the shock absorber rod 6 are driven to rotate. At this time, the buckle cover 14 is threadedly connected to the upper end of the extension shaft 13.

[0031] like Figure 2 As shown, in one possible implementation, the extension shaft 13 and the mounting shaft 7 are arranged in a stepped shape, the steering handle plate 11 is located on the stepped surface, the steering handle plate 11 is connected to the lower end of the extension shaft 13 by a flat key, and the steering handle plate 11 is supported by the stepped surface.

[0032] like Figure 3 As shown, in one possible implementation, the extension shaft 13 and the mounting shaft are provided with a tapered surface, the steering handle plate 11 is sleeved on the tapered surface, and the steering handle plate 11 and the tapered surface are connected by a flat key.

[0033] As one possible implementation, with a support sleeve 12 provided on the mounting shaft 7, the steering handle plate 11 and the mounting shaft 7 are connected by a flat key. In this case, the shaft body formed by the mounting shaft 7 and the steering shaft 3 and the support sleeve 12 simultaneously transmit the steering torque.

[0034] It should be noted that when the support sleeve 12 is not provided, the diameter of the mounting shaft 7 is larger than that of the steering shaft 3 to ensure its strength.

[0035] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
