Description

Technical Field

[0001] This utility model relates to the field of bicycle handlebar technology, and in particular to a folding bicycle handlebar with adjustable handlebar spacing. Background Technology

[0002] The handlebars are one of the core components of a folding bicycle, ensuring both handling and comfort while allowing for quick and reliable folding. Existing folding bicycle handlebars mainly consist of the handlebar crossbars, stem, vertical tube, cable housing, grips, and additional functional components (such as bells, lights, brake levers, shifters, etc.). The most crucial structural difference between folding bicycle handlebars and ordinary bicycles lies in the folding function, primarily focusing on: folding hinges: enabling the physical folding action; locking mechanisms: ensuring a secure lock during riding (most commonly quick-release levers); safety locks / locking devices: preventing accidental opening of the locking mechanism; positioning devices: ensuring precise angle and no wobbling when unfolded; cable management systems: ensuring smooth, undamaged, and tangle-free cable management during folding and unfolding; and vertical tube folding hinges (on some models): enabling the entire handlebar assembly to fold forward.

[0003] However, current split-type folding bicycle handlebars have the problem that the spacing between the left and right handlebars and the stem cannot be adjusted, resulting in insufficient adaptability for users of different body types. This causes the user's arms to be excessively tucked in or out, causing discomfort. Utility Model Content

[0004] Therefore, it is necessary to provide a folding bicycle handlebar with adjustable handlebar spacing to address the problem that existing split folding bicycle handlebars cannot adjust the left and right handlebar width and stem spacing.

[0005] A folding bicycle handlebar with adjustable handlebar spacing includes handlebar crosses, handlebar sleeves, a stem, and a folding mechanism. The handlebar crosses are located at both ends of the stem, and the handlebar sleeves are respectively fitted onto the side surfaces of the handlebar crosses at both ends, thus forming the basic structure of the handlebar.

[0006] The stem is divided into two independent and symmetrically arranged sub-stems by a middle section; correspondingly, there are two mirror-image handlebars, which are respectively located at the outer ends of the two sub-stems; correspondingly, there are two mirror-image handle sleeves, which are respectively fitted onto the two handlebars; a folding mechanism is located between the two sub-stems, and the folding mechanism is connected to the opposite ends of the two sub-stems, so that the spacing between the two sub-stems can be adjusted and folded around the center of the folding mechanism.

[0007] The folding mechanism includes a mating part and a connecting part. The mating part is fitted onto the opposite ends of the two handlebar stems, and the two handlebar stems are movably connected to the inner wall of the mating part. The connecting part is disposed on the outer surface of the mating part relative to the handlebar stems.

[0008] The mating part is provided with two symmetrically arranged L-shaped grooves. The two L-shaped grooves are respectively located at both ends of the inner wall of the mating part, and each L-shaped groove extends outward at a predetermined distance along the length direction of the mating part, and then folds and extends towards the top to form an L-shaped structure. The two stems slide into the mating part through the L-shaped grooves at both ends, so that the two stems can slide and flip along the corresponding L-shaped grooves respectively.

[0009] In one embodiment, each of the above-mentioned stems is provided with a spring positioning bead assembly, which is disposed on the side wall of the stem and extends to the outer side of the side wall of the stem; each stem is connected to the corresponding L-shaped groove through the corresponding spring positioning bead assembly.

[0010] In one embodiment, each of the aforementioned stem members has a through hole corresponding to the L-shaped groove at one end that mates with the mating part. Correspondingly, the spring positioning bead assembly includes a mating part, a fixing part, and an elastic part. The fixing part is connected to the inner wall of the stem member corresponding to the through hole. The mating part mates with the through hole, and mating rods are respectively provided at the inner and outer ends of the mating part relative to the side wall of the stem member. The mating rod at the outer end slides with the L-shaped groove, and the mating rod at the inner end moves with the fixing part. Based on the above configuration, the elastic part is sleeved on the mating rod of the inner section, and the two ends of the elastic part abut against the main body of the mating part and the fixing part, respectively.

[0011] In one embodiment, the main body of the aforementioned mating part is configured as a spherical structure with a slightly larger diameter corresponding to the through hole. Under the action of the elastic element, the mating part normally moves and fits into the through hole, and protrudes to a predetermined height towards the outside of the handlebar.

[0012] In one embodiment, the spherical structure corresponding to the L-shaped groove is provided with a plurality of locking holes, so that when the handlebar slides relative to the mating part to a preset position, the mating part can be inserted into the corresponding locking hole relative to the protrusion of the through hole.

[0013] In one embodiment, each of the above-mentioned L-shaped grooves has a locking hole at its end extending towards the top side. When the corresponding sub-stem slides outward along the horizontal groove of the L-shaped groove, the spring positioning bead assembly can slide along the vertical groove of the L-shaped groove and engage with the locking hole at the end by rotation. At this time, the corresponding sub-stem can swing around the locking hole as the axis.

[0014] In one embodiment, the connecting part is configured as a U-shaped plate, and the two end faces of the U-shaped connecting part are respectively connected to the top and bottom connections of the opposite side surfaces of the mating part, thereby forming a stable connecting structure.

[0015] In one embodiment, the connecting part is provided with a connecting hole that extends from the top side surface of the connecting part to the bottom side surface of the connecting part, so as to allow the connecting part to be connected with the corresponding vertical pipe.

[0016] In one embodiment, the folding mechanism further includes a connecting plate disposed on the bottom side surface of the mating part.

[0017] In one embodiment, the aforementioned adjustable handlebar spacing folding bicycle handlebar also includes two mounting seats, which are respectively fitted onto the side surfaces of the two sub-stems to provide mounting points for the adapted handlebar components.

[0018] In one embodiment, each of the above-described mounting bases is disposed at one end of the corresponding sub-stem transitioning to the handlebar.

[0019] The aforementioned adjustable handlebar spacing folding bicycle handlebars features stems whose spacing is limited by a mating section, enabling both spacing adjustment and folding functionality. The handlebars as a whole connect to the corresponding vertical tube via a connecting section, and then to the head tube of the frame. The mating section has two symmetrically arranged L-shaped grooves; the two stems slide into the mating section through the L-shaped grooves at both ends, allowing them to slide and flip along their respective L-shaped grooves. This expands the adjustment range of the stem spacing and the folding method, thereby improving the folding convenience and versatility of the folding bicycle. Based on the above design, two independent movement dimensions are achieved through the L-shaped groove track (horizontal sliding + vertical flipping): Horizontal sliding segment: the two stems slide laterally along the track, steplessly adjusting the handlebar spacing; Vertical flipping segment: the stems fold upwards, achieving vertical folding. The mirror-symmetric design of the stems / handlebars / handle sheaths ensures independent movement on both sides without interference, improving structural reliability and operational flexibility.

The adjustable handlebar spacing folding bicycle handlebar 1 includes handlebar crossbars 10, handlebar sleeves 20, handlebar stems 30, and a folding mechanism 40. The handlebar crossbars 10 are disposed at both ends of the handlebar stems 30, and the handlebar sleeves 20 are respectively fitted onto the side surfaces of the handlebar crossbars 10 at both ends, thus forming the basic structure of the handlebar. Specifically, the handlebar stems 30 are divided into two independent and symmetrically arranged sub-handlebar stems 31 by a middle section; correspondingly, the handlebar crossbars 10 include two mirror-image sections, respectively disposed at the outer ends of the two sub-handlebar stems 31; correspondingly, the handlebar sleeves 20 include two mirror-image sections, respectively fitted onto the two handlebar crossbars 10; the folding mechanism 40 is disposed between the two sub-handlebar stems 31, and the folding mechanism 40 is connected to the opposite ends of the two sub-handlebar stems 31, thereby enabling the spacing between the two sub-handlebar stems 31 to be adjusted and folded around the center of the folding mechanism 40. More specifically, the folding mechanism 40 includes a mating part 41 and a connecting part 42. The mating part 41 is fitted onto the opposing ends of the two stems 31, and the two stems 31 are movably connected to the inner wall of the mating part 41. The connecting part 42 is disposed on the outer surface of the mating part 41 relative to the stems 31. Based on the above configuration, the two stems 31 can be spaced apart by the mating part 41, while simultaneously achieving spacing adjustment and folding functions. The handlebar as a whole can be connected to the corresponding stem tube by the connecting part 42, and then connected to the head tube of the frame. More specifically, the mating part 41 is provided with two symmetrically arranged L-shaped grooves a. The two L-shaped grooves a are respectively located at both ends of the inner wall of the mating part 41, and each L-shaped groove a extends outward at a predetermined distance along the length direction of the mating part 41, and then folds and extends towards the top to form an L-shaped structure. The two sub-stems 31 are slidably mated to the mating part 41 through the L-shaped grooves a at both ends, so that the two sub-stems 31 can slide and flip along the corresponding L-shaped grooves a respectively, thereby expanding the adjustment range of the spacing between the sub-stems 31 and the folding method, thereby improving the folding convenience of the folding bicycle and its applicability in multiple scenarios.

[0031] Furthermore, each stem 31 is provided with a spring positioning bead assembly 50, which is disposed on the side wall of the stem 31 and extends to the outer side of the side wall of the stem 31; each stem 31 is connected to the corresponding L-shaped groove a through the corresponding spring positioning bead assembly 50, so that the stem 31 can be stably connected to and slide stably with the mating part 41.

[0032] Furthermore, each stem 31 has a through hole b at one end corresponding to the L-shaped groove a, which mates with the mating part 41. Correspondingly, the spring positioning bead assembly 50 includes a mating part 51, a fixing part 52, and an elastic part 53. The fixing part 52 is connected to the inner wall of the stem 31 corresponding to the through hole b. The mating part 51 mates with the through hole b, and mating rods 511 are respectively provided at the inner and outer ends of the mating part 51 relative to the side wall of the stem 31. The mating rod 511 at the outer end slides with the L-shaped groove a, allowing the stem to... The stem 31 can slide with the L-shaped groove a through the outer end mating rod 511, and the mating rod 511 set at the inner end can move with the fixing member 52, so that the mating member 51 can move with the fixing member 52 through the inner end mating rod 511; based on the above configuration, the elastic member 53 is sleeved on the inner section of the mating rod 511, and the two ends of the elastic member 53 abut against the main body of the mating member 51 and the fixing member 52 respectively, so that the elastic member 53 can lift the mating member 51 towards the outside of the side wall of the stem 31.

[0033] Furthermore, the main body of the mating part 41 is configured as a spherical structure with a slightly larger diameter corresponding to the through hole b.

Based on the above configuration, the L-shaped groove a is provided with a plurality of locking holes c corresponding to the spherical structure of the mating part 41, so that when the handlebar stem 31 slides relative to the mating part 41 to the predetermined position, the mating part 41 can be inserted into the corresponding locking hole c relative to the protrusion of the through hole b, thereby locking the relative position of the handlebar stem 31 and the mating part 41.

[0034] Furthermore, each L-shaped groove a has a locking hole c at its end extending towards the top side. When the corresponding sub-stem 31 slides outward along the horizontal groove of the L-shaped groove a, the spring positioning bead assembly 50 can slide along the vertical groove of the L-shaped groove a and engage with the locking hole c at the end by rotation. At this time, the corresponding sub-stem 31 can swing around the locking hole c as the axis, thereby realizing the folding of the two sub-stems 31 towards each other.

[0035] Furthermore, the connecting part 42 is configured as a U-shaped plate, and the two end faces of the U-shaped connecting part 42 are respectively connected to the top and bottom connections of the opposite side surfaces of the mating part 41, thereby forming a stable connection structure. Based on the above configuration, the connecting part 42 is provided with a connecting hole d, which extends from the top side surface of the connecting part 42 to the bottom side surface of the connecting part 42, for the connecting part 42 to be mated and connected with the corresponding vertical pipe.

[0037] Furthermore, the adjustable handlebar spacing folding handlebar 1 also includes two mounting seats 60, which are respectively fitted onto the side surfaces of the two sub-stems 31 to provide mounting points for the adapted handlebar components. Specifically, each mounting seat 60 is located at one end of the corresponding sub-stem 31 where it transitions to the handlebar crossbar 10.

[0038] In summary, the adjustable handlebar spacing folding bicycle handlebars disclosed in this utility model allow the two stems to be spaced through a mating part, simultaneously achieving spacing adjustment and folding functions. The handlebar as a whole can be connected to the corresponding vertical tube through a connecting part, and then connected to the head tube of the frame. The mating part is provided with two symmetrically arranged L-shaped grooves; the two stems slide into the mating part through the L-shaped grooves at both ends, allowing the two stems to slide and flip along the corresponding L-shaped grooves, thereby expanding the adjustment range of the stem spacing and the folding method, thus improving the folding convenience and multi-scenario applicability of the folding bicycle. Based on the above settings, two independent movement dimensions are achieved through the L-shaped groove track (horizontal sliding + vertical flipping): Horizontal sliding segment: the two stems slide laterally along the track, infinitely adjusting the handlebar spacing; Vertical flipping segment: the stems fold upwards to achieve longitudinal folding. The mirror-symmetric design of the stems / handlebars / handle sheaths ensures that the independent movements of the left and right sides do not interfere with each other, improving structural reliability and operational flexibility.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

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