Description

Technical Field

[0001] This utility model relates to the field of front shock absorption technology for electric tricycles, and in particular to a novel front shock absorption structure for electric tricycles. Background Technology

[0002] The front shock absorber of an electric tricycle is a core component that ensures the vehicle's driving safety, stability, and riding comfort. It is usually integrated into the front fork structure and mainly undertakes the functions of buffering road bumps, absorbing impact energy, and stabilizing steering and control.

[0003] To meet the driving needs under different load scenarios, most new electric tricycles currently use adjustable shock absorbers for the front shock absorption. The core principle is to adjust the position of the spring seat to change the compression ratio of the spring, thereby adjusting the stiffness of the shock absorber and improving the driving comfort when unloaded or carrying passengers.

[0004] These shock absorbers, which rely on adjusting the spring seat to switch between soft and hard shocks, have significant limitations in practical operation. Because the spring itself has strong elastic tension, special tools such as screwdrivers and pry bars must be used to forcibly compress the spring before adjustment to unlock the spring seat's fixing structure and adjust its position. This adjustment method is highly dependent on tools. If a user experiences sudden discomfort with the shock absorption in scenarios such as outdoor delivery or driving on rural roads, and does not have the corresponding tools, they cannot adjust the shock absorption performance in time, making it difficult to meet diverse immediate usage needs. Therefore, a novel front shock absorption structure for electric tricycles is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a novel front shock absorption structure for electric tricycles, aiming to solve the problem mentioned in the prior art that "adjustable shock absorbers require tools to compress the springs to achieve adjustment".

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a novel front shock absorption structure for an electric tricycle, comprising a shock absorber, wherein a positioning block is fixedly connected to the outer wall of the piston rod of the shock absorber, a spring is fixedly connected to the bottom of the positioning block, and an adjustment mechanism is provided on the outer wall of the shock absorber;

[0007] The adjustment mechanism includes a sleeve fitted onto the outer wall of the shock absorber. A limiting plate is fixedly connected to the outer wall of the sleeve. A slot is radially formed on the side wall of the limiting plate. A retaining ring is fixedly connected to the outer wall of the shock absorber. A positioning shaft is fixedly connected to the outer wall of the retaining ring. A handle is hinged to the outer wall of the positioning shaft. A push rod is fixedly connected to the side wall of the handle near the positioning shaft. A positioning mechanism is provided inside the handle.

[0008] As a further description of the above technical solution:

[0009] The positioning mechanism includes a slide plate, which is slidably connected to the inner wall of the handle. A plug rod is fixedly connected to one side of the slide plate, and a spring is fixedly connected to the other side of the slide plate.

The upper and lower ends of the slots are arc-shaped structures, and the radius of the arc is the same as the radius of the positioning shaft.

[0016] As a further description of the above technical solution:

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figure 1 - Figure 3 One embodiment of this utility model is a novel front shock absorption structure for an electric tricycle, comprising a shock absorber 1, which is a hydraulic shock absorber. A positioning block 2 is fixedly connected to the outer wall of the piston rod of the shock absorber 1, and a spring 3 is fixedly connected to the bottom of the positioning block 2. The piston rod of the shock absorber 1 can be quickly reset by the elastic push of the positioning block 2 by the spring 3. An adjustment mechanism 4 is provided on the outer wall of the shock absorber 1.

[0030] Reference Figure 2 - Figure 4 The adjustment mechanism 4 includes a sleeve 41, which is fitted onto the outer wall of the shock absorber 1. The sleeve 41 is a hollow cylindrical structure with open ends. The bottom end of the spring 3 abuts against the top of the sleeve 41. The sleeve 41 is used to support the spring 3. The stiffness of the spring 3 can be adjusted through the sleeve 41. A limiting plate 42 is fixedly connected to the outer wall of the sleeve 41. A slot 43 is radially opened on the side wall of the limiting plate 42. The slot 43, in conjunction with the positioning shaft 45, can limit the sleeve 41. A retaining ring 44 is fixedly connected to the outer wall of the shock absorber 1. A positioning shaft 45 is fixedly connected to the outer wall of the retaining ring 44. A handle 46 is hinged to the outer wall of the positioning shaft 45. A push rod 47 is fixedly connected to the side wall of the handle 46 near the positioning shaft 45. Rotating the handle 46 upwards, in conjunction with the push rod 47, can push the limiting plate 42 upwards by lever, allowing the user to easily compress the spring 3. A positioning mechanism 5 is provided inside the handle 46.

[0031] Reference Figure 3 The slots 43 are spirally and equidistantly distributed along the outer circumference of the sleeve 41, and there are at least three sets. Adjacent slots 43 are connected. Multiple sets of slots 43 are spirally and equidistantly distributed on the outside of the sleeve 41. This layout provides a precise and orderly gear position basis for the soft and hard adjustment of the shock absorber 1. The upper and lower ends of the slots 43 are arc-shaped structures, and the radius of the arc is the same as the radius of the positioning shaft 45. The positioning shaft 45 is engaged with the inner wall of the slots 43. The arc-shaped structure at the top of the slots 43, in conjunction with the positioning shaft 45, can limit the sleeve 41 in the radial and horizontal directions, so that the sleeve 41 remains fixed.

[0032] Reference Figure 1 - Figure 3 The positioning mechanism 5 includes a slide plate 51, which is slidably connected to the inner wall of the handle 46. A rod 52 is fixedly connected to one side of the slide plate 51. The sliding of the slide plate 51 can drive the rod 52 to be inserted into or pulled out of the insertion hole 54. A spring 53 is fixedly connected to the other side of the slide plate 51. The elasticity of the spring 53 can push the slide plate 51 to slide and reset on the inner wall of the handle 46. The inner wall of the positioning shaft 45 is radially provided with an insertion hole 54 for the rod 52 to be inserted. The rod 52 and the insertion hole 54 can be used to limit the handle 46, so that the handle 46 and the central axis of the shock absorber 1 can be kept in a stable parallel state. A push block 55 is fixedly connected to the outer wall of the slide plate 51. By pushing the push block 55, the slide plate 51 can be driven to slide on the inner wall of the handle 46.

[0033] Working principle: The pusher 55 pushes the slide plate 51, causing it to slide on the inner wall of the handle 46 and compress the spring 53. At the same time, the slide plate 51 will drive the insertion rod 52 to move out of the insertion hole 54, thereby releasing the insertion rod 52 from the limit of the handle 46. At this time, the handle 46 can be pushed to rotate on the outer wall of the positioning shaft 45.

[0034] When the handle 46 is not needed, rotate the handle 46 to move the plug rod 52 synchronously. When the plug rod 52 is completely aligned with the socket 54 during the movement, the previously compressed spring 53 can push the slide plate 51 to slide back to its original position on the inner wall of the handle 46. At the same time, the slide plate 51 will drive the plug rod 52 to insert into the socket 54. At this time, the plug rod 52 and the socket 54 can be used to limit the handle 46, so that the handle 46 and the central axis of the shock absorber 1 can be kept in a stable parallel state.

[0035] When it is necessary to adjust the stiffness of the shock absorber 1, first release the limiting force of the handle 46 by inserting rod 52, and then rotate the handle 46 upward, causing the handle 46 to drive the push rod 47 to swing upward around the axis of the positioning shaft 45. When the push rod 47 contacts the limiting plate 42, the push rod 47 will push the limiting plate 42 upward, causing the limiting plate 42 to drive the sleeve 41 to move upward on the outer wall of the shock absorber 1 and compress the spring 3. The upward movement of the sleeve 41 allows the positioning shaft 45 to move out of the arc-shaped structure at the top of the slot 43. At this time, the sleeve 41 can be rotated, and while the sleeve 41 is rotating, the positioning shaft 45 will... Move from the inside of slot 43 to the inside of another set of slots 43. After the adjustment is completed, release handle 46 so that it no longer drives top rod 47 to push limit plate 42 upward. At this time, the compressed spring 3 will push sleeve 41 downward, so that sleeve 41 slides downward on the outer wall of shock absorber 1. After sleeve 41 slides downward, positioning shaft 45 will be locked into the arc-shaped structure at the top of slot 43 again. At this time, the arc-shaped structure at the top of slot 43, together with positioning shaft 45, can limit sleeve 41 in the radial and horizontal directions, so that sleeve 41 is kept in a fixed state, thereby completing the adjustment of the stiffness of shock absorber 1.

[0036] Multiple sets of slots 43 are evenly distributed on the outside of the sleeve 41 in a spiral structure. This layout provides a precise and orderly basis for adjusting the stiffness of the shock absorber 1. When the positioning shaft 45 is engaged in the bottom slot 43, the sleeve 41 is at its highest position under the limiting action of the positioning shaft 45 and the slot 43. At this time, the axial compression force of the sleeve 41 on the spring 3 reaches its maximum, and the spring 3 is compressed to its maximum deformation state. The elastic tension of the spring 3 is significantly enhanced, which makes the shock absorber 1 exhibit a stiffer working state, which can effectively cope with road impacts under heavy loads and prevent the fork from sinking excessively. When the positioning shaft 45 is switched to the top slot 43, the sleeve 41 moves down to the lowest position. The previously compressed spring 3 is released and elastically reset. The compression amplitude is greatly reduced, and the elastic tension is correspondingly weakened. The shock absorber 1 then switches to a softer working state, which can more fully absorb road bumps and improve the riding comfort when unloaded or carrying passengers. By cooperating with the positioning shaft 45 and the slots 43 of different heights, the up and down position of the sleeve 41 can be adjusted, thereby changing the compression force and deformation of the spring 3, and finally achieving convenient adjustment of the soft and hard state of the shock absorber 1.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
