[0002] A recumbent bicycle is a bicycle with a seat and backrest, offering two riding styles: recumbent and normal. In recumbent riding, the user's back rests against the seat backrest; in normal riding, the user's back is separated from the seat backrest. Clearly, the user adopts two distinct postures in these two riding styles. To ensure comfortable riding in both postures, some bicycles now feature an angle adjustment mechanism between the front fork and stem. This mechanism adjusts the angle between the handlebars and stem, locking it in place once a suitable angle is achieved. This allows the user to ride comfortably in both recumbent and normal riding positions.

[0041] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0042] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other. The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0043] Please see Figures 1-9 This utility model provides a ring-locking angle adjustment structure for semi-reclining non-motorized vehicles. The semi-reclining non-motorized vehicle can be a semi-reclining bicycle, a semi-reclining tricycle, or an electric scooter. One end of the ring-locking angle adjustment structure is connected to the handlebar stem, and the other end is connected to the front fork. The ring-locking angle adjustment structure is used to adjust the ring-locking angle, and after adjustment to a suitable angle, locks the handlebar stem and front fork to accommodate different riding postures. Of course, its application is not limited to the handlebar stem and front fork; it is suitable for any two of the adjustable angle structures in semi-reclining bicycles, semi-reclining tricycles, and electric scooters.

[0044] Please see Figure 1 and Figure 2The circumferential locking angle adjustment structure includes: a base 10, a rotating member 20, clamps 30, and a locking assembly 40. The rotating member 20 is rotatably mounted on the base 10, and the clamps 30 are respectively sleeved on the peripheral wall of the base 10. The first end of each clamp 30 is hinged to the rotating member 20, and the second end is detachably connected to the rotating member 20. The locking assembly 40 is detachably connected to both the base 10 and the rotating member 20.

[0045] The present invention relates to a ring-locking adjustment mechanism in which a clamp 30 is fitted onto the peripheral wall of a rotating base. The first end of the clamp 30 is hinged to the base 10, and the second end is mutually locked to the base 10, thereby achieving a single locking of the base 10 and the rotating component 20. A locking assembly 40 is provided, which is mutually locked to the base 10 and locked to a limiting member, achieving a double locking of the base 10 and the rotating component 20. The double locking of the clamp 30 and the locking assembly 40 improves the locking stability of the ring-locking adjustment mechanism, resulting in strong safety.

[0046] The rotating member 20 is rotatably mounted on the base 10, and can rotate relative to the base 10. That is, the angle-adjusting ring locking structure is adjusted by the internal structure of the ring locking structure. Furthermore, the rotating member 20 is in direct contact with the base 10, and the rotation direction of the rotating member 20 is clockwise or counterclockwise along its own axial direction.

[0047] Two clamps 30 are provided, each sleeved onto the peripheral wall of the rotating member 20. When the clamps 30 are locked to the base 10, the clamps 30 utilize the static friction between themselves and the rotating member 20 to lock the rotating member 20, restricting its rotation relative to the base 10. Correspondingly, when the second end of the clamp 30 separates from the base 10, the rotating member 20 can rotate relative to the base 10.

[0048] It should be noted that: the locking component 40 is fixed to the base 10 during use, but is disassembled into two parts when adjusting the angle. The locking component 40 is fixed to the rotating component 20 during use, but is disassembled into two parts when adjusting the angle.

[0049] When the rotating part 20 rotates relative to the base 10, the locking assembly 40 and the base 10 are disassembled into two parts, or the locking assembly 40 and the rotating part 20 are disassembled into two parts.

[0050] In one specific embodiment, the locking component 40 includes a limiting baffle 45, which is detachably connected to the base 10 and detachably connected to the rotating component 20.

[0051] The limiting baffle 45 is detachably connected to the base 10. During use, the limiting baffle 45 and the base 10 are fixed together; when adjusting the angle, they are detached from the base 10 and become two separate parts. The limiting baffle 45 is also detachably connected to the rotating component 20. During use, the limiting baffle 45 and the rotating component 20 are fixed together; when adjusting the angle, they are detached from the rotating component 20 and become two separate parts.

[0052] The limiting baffle 45 is detachably connected to the base 10 and the rotating member 20, so that the base 10 and the rotating member 20 are fixed to each other. When the limiting baffle 45 and the base 10 are disassembled into two parts, or when the limiting baffle 45 and the rotating member 20 are disassembled into two parts, the rotating member 20 rotates relative to the base 10.

[0053] Furthermore, the limiting baffle 45 is provided with a first locking part 451, and the rotating member 20 is provided with a second locking part 25. Fasteners are inserted through the first locking part 451 and the second locking part 25 to fix the limiting baffle 45 and the rotating member 20.

[0054] The fastener can be a screw. Locking the limit baffle 45 and the rotating part 20 by tightening the screw can effectively overcome radial external forces, with high locking strength and reliable locking effect.

[0055] Please continue reading. Figure 3 and Figure 4 In one specific embodiment, the base 10 has a first end and a second end disposed opposite to each other. A receiving cavity 11 is formed in the second end of the base 10, and a limiting baffle 45 is detachably covered at the opening of the receiving cavity 11. The opening of the receiving cavity 11 is located at the second end of the base 10.

[0056] It should be further noted that the locking assembly also includes a fixed seat 41 and a support 42, both of which are located within the receiving cavity 11. Thus, the arrangement of the receiving cavity 11 fully utilizes the internal space of the base 10, making the circumferential locking angle adjustment structure more compact. Furthermore, the limiting baffle 45 protects the fixed seat 41 and support 42 inside the receiving cavity 11, preventing foreign objects from entering and affecting the fit between the fixed seat 41 and support 42. This results in more stable operation and a longer service life for the circumferential locking angle adjustment structure.

[0057] When the fastener passes through the first locking part 451 and the second locking part 25, the limiting baffle 45 is locked onto the base 10. That is, the limiting baffle 45 is fixed relative to the base 10, and the limiting baffle 45 cannot rotate or move linearly relative to the base 10 in any direction. When the fastener is removed from the first locking part 451 and the second locking part 25, the limiting baffle 45 can be removed from the base 10.

[0058] Preferably, the limiting baffle 45 is threadedly connected to the base 10.

[0059] Please see Figure 3 , Figure 4 and Figure 8 Specifically, the outer peripheral wall of the limiting baffle 45 is provided with a first internal thread 452, and the inner peripheral wall of the base 10 is provided with a first external thread 12 that is adapted to the first internal thread 452.

[0060] The threaded connection can lock the limit baffle 45 and the base 10, effectively preventing external forces in the axial direction from acting on the limit baffle 45, and the locking effect is stable and reliable.

[0061] When the fastener is inserted through the first locking part 451 and the second locking part 25, the limiting baffle 45 is locked onto the base 10. That is, the limiting baffle 45 and the base 10 cannot rotate relative to each other. When the fastener is removed from the first locking part 451 and the second locking part 25, the limiting baffle 45 and the base 10 can be rotated open or closed.

[0062] In other alternative embodiments, the limiting baffle 45 and the base 10 can be detachably connected by a snap-fit ​​groove or a pin-hole.

[0063] For example, the limiting baffle 45 has a buckle, and the base 10 has a slot. The buckle of the limiting baffle 45 engages with the slot of the base 10 to lock the limiting baffle 45 and the base 10 together. When the buckle of the limiting baffle 45 disengages from the slot of the support 42, the limiting baffle 45 and the support 42 can be separated. The limiting baffle 45 has a slot, and the base 10 has a pin. When the pin of the base 10 is inserted into the slot of the limiting baffle 45, the limiting baffle 45 and the support 42 are locked together. When the pin of the support 42 disengages from the slot of the limiting baffle 45, the limiting baffle 45 and the support 42 can be separated.

[0064] To further improve the locking strength of the limiting baffle 45, in one specific embodiment, the locking assembly 40 further includes a limiting screw 43. The limiting baffle 45 is hollow, the limiting screw passes through the limiting baffle 45, and is detachably connected to the base 10.

[0065] An axial through hole is provided at the geometric center of the limiting baffle 45. The limiting screw 43 passes through this through hole and enters the receiving cavity 11. A lateral hole is provided on the base 10 for the limiting screw 43 to pass through, so as to achieve the positioning of the limiting screw 43. The lateral hole is a threaded hole, which allows the limiting screw 43 to be screwed into the lateral hole and suspended at any position, so that the limiting screw 43 can provide different limiting heights according to the usage requirements.

[0066] The limiting screw 43 can limit the radial movement of the limiting baffle 45, further improving the installation strength of the limiting baffle 45 and ensuring stable and reliable locking.

[0067] In one specific embodiment, the locking assembly 40 further includes a fixing seat 41, a support 42, and an elastic element 44. The fixing seat 41 is fixedly disposed on the bottom wall of the receiving cavity 11. The elastic element 44 is sleeved on the limiting screw 43, with one end of the elastic element 44 abutting against the bottom wall of the receiving cavity 11 and the other end of the elastic element 44 abutting against the support 42. The support 42 is sleeved on the limiting screw 43 and passes through the limiting baffle 45.

[0068] The fixed base 41 and the support 42 switch between a locked state and a released state. In the locked state, the limiting screw 43 restricts the position of the elastic element 44 so that the support 42 is fixed on the fixed base 41. In the released state, the limiting screw 43 remains stationary, and the elastic element 44 drives the support 42 to move relative to the fixed base 41 until the support 42 moves to the head of the limiting screw 43. At this time, the support 42 and the limiting baffle 45 are detachably connected.

[0069] Both the fixed base 41 and the support 42 are hollow, and the limiting screw 43 passes through the fixed base 41, the support 42 and the base 10. The limiting screw 43 is used to limit the height of the elastic element 44 that lifts the support 42.

[0070] The locking assembly 40, through the fixed base 41, the support 42, and the elastic element 44, locks the limit baffle 45 with the support 42, further improving the locking stability of the limit baffle 45. Furthermore, by controlling the position of the limit screw 43 within the lateral hole, the positional relationship between the support 42 and the fixed base 41 can be effectively adjusted, allowing the support 42 to quickly switch between locked and released states, making operation simple and convenient.

[0071] It should be noted that the elastic element 44 can be a tension spring, but it is not limited to this form. Although the support 42 and the fixed seat 41 move relative to each other, the support 42 remains in contact with the fixed seat 41. In the locked state, the support 42 is not detachably connected to the limit baffle 45. In the released state, the support 42 is detachably connected to the limit baffle 45.

[0072] Furthermore, the limiting baffle 45 is threadedly connected to the support 42.

[0073] Please see Figure 7 and Figure 8Specifically, the limiting baffle 45 is hollow, and its inner peripheral wall is provided with a second external thread 453. The support 42 is provided with a second internal thread 422 that matches the second external thread 453. When the fixed seat 41 and the support 42 are in the released state, the second external thread 453 of the limiting baffle 45 and the second internal thread 422 of the support 42 are threadedly connected to each other. In this way, the limiting baffle 45 and the support 42 are threadedly connected, and the locking and separation of the limiting baffle 45 and the support 42 can be achieved simply by rotating the limiting baffle 45 relative to the support 42. The locking strength is high, which further improves the stability of locking the limiting baffle 45.

[0074] Of course, the limit baffle 45 and the support 42 are not limited to a threaded connection. The limit baffle 45 and the support 42 can also be locked by the cooperation of limit teeth and limit grooves, snap-fit ​​grooves or pin slots.

[0075] Specifically, the limiting baffle 45 has one or more limiting teeth in its circumferential direction, and the support 42 has one or more limiting grooves that are adapted to the limiting teeth. When the limiting baffle 45 and the support 42 are in the released state, the limiting teeth are engaged in the limiting grooves. When the limiting baffle 45 and the support 42 are in the locked state, the limiting teeth disengage from the limiting grooves.

[0076] In one embodiment, multiple limiting teeth cover the peripheral wall of the support 42. The density of the limiting teeth can be adjusted according to actual needs, thereby adjusting the adjustment range of the support 42 and the limiting baffle 45 in one step. For example, if the distance between two adjacent limiting teeth of the support 42 is 10°, then the minimum adjustment angle between the support 42 and the limiting baffle 45 is 10°. If the distance between two adjacent limiting teeth of the support 42 is 6°, then the minimum adjustment angle between the support 42 and the limiting baffle 45 is 6°.

[0077] For example, the limiting baffle 45 has a buckle, and the support 42 has a slot. When the limiting baffle 45 and the support 42 are in the released state, the buckle of the limiting baffle 45 engages with the slot of the support 42 to lock. When the limiting baffle 45 and the support 42 are in the locked state, the buckle of the limiting baffle 45 disengages from the slot of the support 42. The limiting baffle 45 has a slot, and the support 42 has a pin. When the limiting baffle 45 and the support 42 are in the released state, the pin of the support 42 is inserted into the slot of the limiting baffle 45. When the limiting baffle 45 and the support 42 are in the locked state, the pin of the support 42 disengages from the slot of the limiting baffle 45.

[0078] Furthermore, the fixed base 41 is square, and the support 42 has a square limiting groove that matches the shape of the fixed base 41. In this way, when the support 42 is fitted onto the fixed base 41, the support 42 cannot rotate relative to the fixed base 41, further improving the stability of the locking of the limiting baffle 45.

[0079] In one specific embodiment, the locking assembly 40 further includes a press cover 46, a hollow limiting baffle 45, and an extension 421 at one end of the support 42 (see [reference]). Figure 7 The extension 421 passes through the hollow part of the limiting baffle 45, and the pressing cover 46 is located at the free end of the extension 421. Thus, when the extension 421 is a cylindrical body, the pressing cover 46 can, on the one hand, block the extension 421 to prevent the limiting screw 43 from directly contacting the outside, and on the other hand, by pressing the pressing cover 46 axially toward the base 10, the pressing cover 46 can drive the support 42 to engage with the fixed seat 41, so that the support 42 and the fixed seat 41 are locked together. The user only needs to press the pressing cover 46 to lock the circumferential locking angle adjustment structure into the locked state without opening the limiting baffle 45. The operation is simple and quick, and highly interactive.

[0080] It should be noted that the press cover 46 is fixedly installed on the support 42. Of course, the press cover 46 and the support 42 can also be integrally formed.

[0081] In summary, the working principle of the locking component 40 is explained as follows:

[0082] Taking a semi-reclining bicycle as an example, when the user needs to lock the position of the handlebars and fork, they apply axial force to the base 10 to press the pressing cover 46. The pressing cover 46 drives the support 42 to move towards the bottom wall of the receiving cavity 11 until the pressing cover 46 is locked onto the fixed seat 41. The elastic element 44 contracts under the pressure of the support 42.

[0083] First, a limiting screw 43 is inserted through the support 42 and the fixed base 41 and screwed into the lateral hole to limit the highest position of the support 42. The elastic element 44 restores its elastic deformation to drive the support 42 toward the head of the limiting screw 43. Then, the limiting baffle 45 is rotated to cover the opening of the receiving cavity 11 and threaded to the support 42, so that the support 42 limits the limiting baffle 45, and the base 10 limits the limiting baffle 45. Finally, the first locking part 451 and the second locking part 25 of the limiting baffle 45 are locked with fasteners to lock the limiting baffle 45 and the rotating element 20, thereby restricting the limiting baffle 45 to be relatively fixed to the base 10 or the support 42 and preventing relative rotation.

[0084] Correspondingly, when the user adjusts the angle between the handlebars and the fork, the fasteners are first removed from the first locking part 451 and the second locking part 25 to allow the limiting baffle 45 to rotate relative to the base 10 and the support 42. However, the limiting baffle 45 needs to be rotated to separate it from the base 10 and the support 42; finally, the press cover 46 is removed from the support 42, and the limiting screw 43 is unscrewed from the side hole. Thus, the locking effect of the locking assembly 40 is lost between the base 10 and the rotating member 20, and with the clamp 30 released, the rotating member 20 can rotate relative to the base 10 to accommodate the user's adjustment of the handlebar and fork angle.

[0085] The base 10 and the rotating member 20 can be detachably connected based on the detachable connection between the locking component 40 and the base 10, and the detachable connection between the locking component 40 and the rotating member 20. In other alternative embodiments, the locking component 40 can be modified.

[0086] Combination Figure 3 and Figure 4 In short, based on the aforementioned locking assembly 40, the limiting screw 43 and the pressing cover 46 are removed, and the extension 421 of the support 42 is solidified.

[0087] Please see Figure 9 The locking assembly 40 includes a fixed base 41, a support 42, an elastic element 44, and a limiting baffle 45. The support 42 is mounted on the fixed base 41. The elastic element 44 is located on the bottom wall of the receiving cavity 11 and on the support 42, and is used to support the support 42 in a detachable connection with the limiting baffle 45. The support 42 and the limiting baffle 45 are threaded together. The limiting baffle 45 is hollow, and the extension 421 of the support 42 is solid and passes through the limiting baffle 45.

[0088] Since the limiting screw 43 and the press cover 46 are eliminated, the solid setting of the extension 421 can increase its own mechanical strength, and there is no need to reserve space for the limiting screw 43, and there is no need to use the press cover 46 to open the space inside the extension 421 to install or remove the limiting screw 43.

[0089] In this embodiment, the structure of the locking component 40 is designed in such a way that the structure is simpler, the assembly is simpler and faster, the manufacturing cost is reduced, and the practicality is stronger.

[0090] Please see Figure 5 and Figure 6 In one specific embodiment, the first end of the clamp 30 is provided with a first fixing hole 32, and the second end of the clamp 30 is provided with a sleeve 31.

[0091] The rotating component 20 is provided with a second fixing hole 26 that matches the first fixing hole 32. Specifically, the first fixing hole 32 is arranged circumferentially towards the rotating component 20, and the second fixing hole 26 is arranged circumferentially towards the rotating component 20. There are two clamps 30, each clamp is provided with a first fixing hole 32, and the rotating component 20 is provided with two second fixing holes 26, which are respectively matched with the two first fixing holes 32 of the two clamps 30.

[0092] Fasteners are inserted through the first fixing hole 32 and the second fixing hole 26 to lock the clamp 30 and the rotating member 20 together, and the degree of tightening of the clamp 30 is adjusted by the tightness of the fasteners. Thus, the clamp 30 can adapt to different sizes of ring-locking angle-adjusting structures, making it highly versatile. Furthermore, the tightness of the clamp 30 can be adjusted according to the fasteners, making it flexible and reliable in use.

[0093] The clamp 30 is fitted onto the peripheral wall of the rotating component 20. The curvature of the clamp 30 is adapted to the peripheral wall of the rotating component 20, so that the clamp 30 can be fixedly positioned relative to the base 10 when locked with the rotating component 20.

[0094] Furthermore, the opening of the sleeve 31 is oriented axially toward the rotating member 20, and the first fixing hole 32 is oriented circumferentially toward the rotating member 20. Thus, the opening direction of the sleeve 31 can be adapted to the rotating member 20, allowing the sleeve 31 to rotate relative to the rotating member 20. The specific structure will be described in detail below. The first fixing hole 32 can be positioned opposite to the second fixing hole 26.

[0095] Please refer to it again. Figure 1 and Figure 2 In one specific embodiment, the sleeves 31 of the two clamps 30 are provided with a first rotating shaft 24; the rotating part 20 is provided with two lugs 21, the two lugs 21 are provided with a second rotating shaft 22, and the first rotating shaft 24 and the second rotating shaft 22 are provided with a connecting seat 23.

[0096] Specifically, the first rotating shaft 24 is fixedly sleeved on the sleeve 31 of the clamp 30, the second rotating shaft 22 is fixedly sleeved on the two lugs 21, and the connecting seat 23 is rotatably sleeved on the first rotating shaft 24 and the second rotating shaft 22. Thus, when the clamp 30 switches between the locked and released states, the connecting seat 23 rotates around the first rotating shaft 24 and around the second rotating shaft 22, so as to realize that the clamp 30 locks the connecting member away from the peripheral wall of the rotating member 20.

[0097] Furthermore, the first rotating shaft 24 is eccentrically positioned relative to the sleeve 31.

[0098] It should be noted that the axis of the first rotating shaft 24 is offset from the axis of the sleeve 31 of the clamp 30. This offset allows the clamp 30 to move more smoothly relative to the first rotating shaft 24 and the sleeve 31, making the disassembly and removal of the clamp 30 from the first rotating shaft 24 quicker. That is, the entire first rotating shaft 24, the second rotating shaft 22, the connecting seat 23, and the two lugs 21 form a quick-release structure.

[0099] Of course, the first end of the clamp 30 may only have the first fixing hole 32, or the second end of the clamp 30 may only have the sleeve 31. Alternatively, other structures may be used to ensure that the first end of the first clamp 30 is detachable from the rotating part 20, and the second end is fixedly connected to the first rotating shaft 24.

[0100] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom still fall within the protection scope of this invention.
