Description

Technical Field

[0001] This application relates to the field of mobility scooter technology, and more particularly to a folding handlebar and a mobility scooter. Background Technology

[0002] The handlebars of scooters and other mobility scooters typically consist of a base and a handlebar assembly. To reduce the space occupied when folded, some scooter handlebar assemblies can be rotated relative to the base to switch from an unfolded state to a folded state.

[0003] In related technologies, the unfolded handlebar assembly typically utilizes a threaded locking structure or a spring-loaded tensioning structure to achieve quick locking with the base. However, threaded locking and spring-loaded tensioning structures cannot eliminate the mating gap between the base and the handlebar assembly, resulting in the handlebar assembly wobbling in the unfolded state, affecting the user's operating experience and even posing a riding safety risk. Utility Model Content

[0004] In view of this, embodiments of this application aim to provide a folding handlebar and a mobility scooter that can keep the handlebar assembly stable in the unfolded state.

[0006] In one embodiment, the backlash elimination block abuts against the handle assembly and the base respectively to achieve an anti-rotation engagement between the backlash elimination block and the handle assembly; And / or, the force application component includes a first force application element and a transmission structure that is respectively connected to the first force application element and the backlash elimination structure.

[0007] In one embodiment, the first force-applying member is rotatably connected to the base, and the transmission structure includes an eccentric rotating member connected to the first force-applying member and a transmission member that is tractively connected to the eccentric rotating member and the backlash elimination structure, respectively. Under the action of an external force, the first force-applying member drives the eccentric rotating member to rotate eccentrically around the rotation axis of the first force-applying member, so that the transmission member drives the backlash elimination block to move between the locked position and the unlocked position under the force of the eccentric rotating member.

[0008] In one embodiment, the eccentric rotating component is one of an eccentric wheel and a crankshaft; And / or, the transmission member has a mounting hole, and the eccentric rotating member is rotatably disposed within the mounting hole.

[0009] In one embodiment, there are two handle assemblies and two gap-eliminating structures. The two handle assemblies are respectively disposed on opposite sides of the base, and the gap-eliminating structures correspond one-to-one with the handle assemblies. The folding handlebar also includes a connecting rod that is connected to the transmission structure, and the two backlash elimination structures are respectively disposed at opposite ends of the connecting rod; the transmission structure drives the connecting rod to move, so that the connecting rod drives the two backlash elimination structures to move between the locked position and the unlocked position.

[0011] In one embodiment, the base has a near rider side and a far rider side on opposite sides along a first direction, the first force-applying member is located on the near rider side of the base, and the gap-eliminating block is located on the far rider side of the base.

[0012] In one embodiment, the connector is movably connected to the mounting base, and the connector moves relative to the mounting base under the action of an external force to adjust the distance between the gap-eliminating block and the mounting base.

[0013] In one embodiment, the gap-eliminating structure further includes an elastic anti-loosening member, one end of which abuts against the mounting base, and the other end of which abuts against the connector or the gap-eliminating block.

[0014] In one embodiment, the folding handlebar includes a guide member with a guide channel, the guide member being disposed on the base; The gap-eliminating structure includes a mounting base and a connector. The connector is connected to the mounting base and the gap-eliminating block respectively. The mounting base is slidably inserted into the guide channel. Alternatively, the gap-eliminating block may be slidably inserted into the guide channel.

[0015] In one embodiment, the base has a first receiving groove, and when the gap-eliminating structure is in the locked position, at least a portion of the gap-eliminating block is located within the first receiving groove; And / or, the handle assembly has a second receiving groove, in which at least a portion of the gap-eliminating block is located when the gap-eliminating structure is in the unlocked position.

[0016] In one embodiment, the folding handlebar further includes a locking assembly disposed on one of the base and the handlebar assembly, and engaging with the other lock to lock the unfolded handlebar assembly.

[0017] In one embodiment, the locking assembly includes a pin retractably disposed in one of the base and the handle assembly, the other of the base and the handle assembly having a locking groove, the pin extending into the locking groove to lock the handle assembly when it is extended.

[0018] In one embodiment, one of the base and the handle assembly has a mounting groove, and the locking groove is disposed in the other of the base and the handle assembly. The mounting groove communicates with the locking groove, and the pin is slidably disposed in the mounting groove. A portion of the structure of the pin can extend into the locking groove from the communication between the mounting groove and the locking groove.

[0019] In one embodiment, the locking assembly further includes an elastic reset member and a second force-applying member connected to the pin. The elastic reset member abuts against the pin and the groove wall of the mounting groove, respectively. The second force-applying member is located outside the mounting groove. The pin extends into the locking groove under the elastic force of the elastic reset member. Under the action of an external force, the second force-applying member drives the pin to disengage from the locking groove, thereby unlocking the locking assembly.

[0020] In one embodiment, the locking assembly includes a second force-applying member, an elastic tension member, and hooks respectively connected to the second force-applying member and the elastic tension member. The end of the elastic tension member opposite to the hook is connected to one of the base and the handle assembly. Under the action of an external force, the second force-applying member drives the hook to engage with the other one.

[0021] Another embodiment of this application provides a personal mobility vehicle, including the folding handlebars described above.

[0022] In one embodiment, the mobility scooter further includes an electronic component disposed on the handlebar assembly and a cable connected to the electronic component. The handlebar assembly has a first cable passage, and the base has a second cable passage communicating with the first cable passage. At least a portion of the cable is located within the first cable passage and the second cable passage.

[0023] This application provides a folding handlebar and a personal mobility vehicle. The folding handlebar includes a base, a handlebar assembly, a backlash elimination structure, and a force-applying component. The handlebar assembly rotates relative to the base to switch between an unfolded and a folded state. When the handlebar assembly switches from the folded to the unfolded state, the user can operate the force-applying component to move the backlash elimination structure from an unlocked position to a locked position. In the locked position, the backlash elimination block of the backlash elimination structure engages with the handlebar assembly to prevent relative rotation, thus ensuring the handlebar assembly remains stably in the unfolded state. Furthermore, it effectively eliminates any wobbling caused by assembly gaps between the handlebar assembly and the base. Therefore, the folding handlebar of this application, by engaging the backlash elimination block with the handlebar assembly to prevent rotation, can maintain stability of the handlebar assembly in the unfolded state, thereby improving the user's operating experience.

Detailed Implementation

[0026] This application provides a folding handlebar; please refer to [link / reference]. Figures 1 to 10 The folding handlebar includes a base 10, a handlebar assembly 20, a gap-eliminating structure 30, and a force-applying assembly 40.

[0027] The handle assembly 20 is rotatably disposed on the base 10, and the handle assembly 20 can switch from an unfolded state to a folded state by rotating relative to the base 10.

[0028] The unfolded state refers to the working state in which the handle assembly 20 pivots around its connection point with the base 10 and unfolds to a predetermined position, so that the handle assembly 20 and the base 10 together form a stable load-bearing frame, capable of safely bearing external operating loads. The folded state refers to the non-working state in which the handle assembly 20 is folded close to or parallel to the base 10 by pivoting around its connection point with the base 10, thereby forming a compact overall profile for easy packaging and storage.

[0029] The structure of the handle assembly 20 is not limited; for example, please refer to [link to relevant documentation]. Figure 2 , Figure 9 and Figure 10The handle assembly 20 may include a handle body 21 (body 311) and a folding seat 22 rotatably connected to the base 10. The folding seat 22 has an assembly hole. A portion of the handle body 21 (body 311) is located in the assembly hole and is interference-fitted with the assembly hole, thereby achieving stable installation of the handle body 21 (body 311).

[0030] Please see Figure 2 , Figure 5 and Figure 9 The folding handlebar may also include a first rotating shaft 80, and the handlebar assembly 20 is rotatably connected to the base 10 via the first rotating shaft 80.

[0031] Preferably, the base 10 can be integrally cast to improve assembly accuracy and reduce the assembly gap between it and the handle assembly 20.

[0032] Please continue reading. Figures 1 to 7 , Figure 9 The gap-eliminating structure 30 is movably disposed on the base 10, and includes a gap-eliminating block 31. Under the action of an external force, the force-applying component 40 drives the gap-eliminating structure 30 to move between a locked position and an unlocked position. Specifically, when the handle assembly 20 is in the extended state, the gap-eliminating structure 30 is in the locked position, and the gap-eliminating block 31 engages with the handle assembly 20 to prevent rotation, thus keeping the handle assembly 20 in the extended state. When the gap-eliminating structure 30 moves from the locked position to the unlocked position under the action of the force-applying component 40, the anti-rotation engagement between the gap-eliminating block 31 and the handle assembly 20 is released, allowing the handle assembly 20 to rotate relative to the base 10.

[0033] The user applies force to the force-applying component 40, which in turn causes the backlash-eliminating structure 30 to move between a locked position and an unlocked position. The locked position refers to the position where the backlash-eliminating block 31 is in a position that restricts the relative rotation of the handle assembly 20, while the unlocked position refers to the position where the backlash-eliminating block 31 is in a position that does not restrict the relative rotation of the handle assembly 20.

[0034] The anti-rotation fit means that the backlash block 31 can prevent the handle assembly 20 from rotating relative to the base 10. In other words, when the handle assembly 20 is in the unfolded state and the backlash block 31 is in the locked position, the backlash block 31 can constrain the rotation of the handle assembly 20.

[0035] Since the anti-rotation engagement of the backlash block 31 with the handle assembly 20 is accompanied by the reaction force exerted by the handle assembly 20 on the backlash block 31, the backlash block 31 can be made of high-strength steel. More preferably, it can be produced by forging process to improve the structural strength of the backlash block 31.

[0036] For example, please refer to Figure 2 , Figure 4 , Figure 6 , Figure 7 and Figure 9 The gap-eliminating structure 30 may also include a mounting base 32 and a connector 33, wherein the connector 33 is connected to the mounting base 32 and the gap-eliminating block 31 respectively.

[0037] Mounting base 32 is used to mount gap-eliminating block 31, and connector 33 is used to connect gap-eliminating block 31 and mounting base 32.

[0038] Preferably, the connector 33 can be movably connected to the mounting base 32. Under the action of external force, the connector 33 moves relative to the mounting base 32 to adjust the distance between the backlash elimination block 31 and the mounting base 32. When the backlash elimination block 31 wears down due to long-term use, resulting in insufficient locking force of the backlash elimination block 31, the locking force between the backlash elimination block 31 and the handle assembly 20 can be adjusted by adjusting the distance between the backlash elimination block 31 and the mounting base 32. This can improve the service life of the backlash elimination assembly and enhance the user experience.

[0039] The type of connector 33 is not limited; for example, please refer to [link to relevant documentation]. Figure 2 , Figure 4 , Figure 6 , Figure 7 and Figure 9 The connector 33 can be a bolt, screw or other fastener, and the connector 33 is threadedly engaged with the mounting base 32.

[0040] Please see Figure 2 , Figure 4 , Figure 6 , Figure 7 and Figure 9 The gap-eliminating structure 30 may also include an elastic anti-loosening element 34, one end of which abuts against the mounting base 32, and the other end of which abuts against the connector 33 or the gap-eliminating block 31. That is, the elastic anti-loosening element 34 is in a compressed state to generate a continuous preload through elastic deformation, compensating for assembly gaps caused by vibration. At the same time, the elastic anti-loosening element 34 can also absorb vibration energy through elastic buffering, preventing the connector 33 and the gap-eliminating block 31 from failing to connect due to vibration, thereby improving the installation stability of the connector 33 and the gap-eliminating block 31.

[0041] The type of elastic anti-loosening element 34 is not limited; for example, Figure 2 , Figure 4 , Figure 6 , Figure 7 and Figure 9 The elastic anti-loosening element 34 is a cylindrical spring, and the connecting element 33 is a fastener such as a bolt or screw. The cylindrical spring is sleeved on the connecting element 33, which not only generates axial preload but also restricts the rotation of the connecting element 33 relative to the mounting base 32, thereby further preventing loosening. In other embodiments, the elastic anti-loosening element 34 may also be a spring washer.

[0042] Another embodiment of this application provides a mobility scooter that includes the folding handlebars provided in any embodiment of this application.

[0043] Personal mobility vehicles are vehicles used for short-distance personal mobility, as opposed to conventional passenger cars. Examples include, but are not limited to, electric scooters and electric bicycles.

[0044] For example, please refer to Figure 4 , Figure 9 and Figure 10 The mobility scooter may also include electronic components disposed on the handlebar assembly 20 and cables connected to the electronic components. The handlebar assembly 20 has a first cable passage 20c, and the base 10 has a second cable passage 10c communicating with the first cable passage 20c. At least a portion of the cable structure is located within the first cable passage 20c and the second cable passage 10c.

[0045] Electronic components include, but are not limited to, turn signals, turn switches, Hall effect brake levers, and shifters. Electrical connection refers to the conductive connection between the electronic components and the vehicle's control module via cables capable of transmitting electrical signals.

[0046] By setting a first cable passage 20c and a second cable passage 10c in the handle assembly 20 and the base 10 respectively, the cable can be hidden inside the handle assembly 20 and the base 10, which not only protects the cable but also improves the appearance of the mobility scooter.

[0047] Please see Figure 2 and Figure 8 The base 10 may include a base 11 and a cover 12 detachably disposed on the base 11. The base 11 and the cover 12 together enclose the second cable passage 10c. Since the cover 12 can be separated from the base 11, it can facilitate the wiring of cables and also facilitate the assembly of the gap elimination structure 30.

[0048] The folding handlebar of this embodiment includes a base 10, a handlebar assembly 20, a backlash elimination structure 30, and a force application component 40. The handlebar assembly 20 rotates relative to the base 10 to switch between an unfolded and a folded state. When the handlebar assembly 20 switches from the folded to the unfolded state, the user can operate the force application component 40 to move the backlash elimination structure 30 from the unlocked position to the locked position. In the locked position, the backlash elimination block 31 of the backlash elimination structure 30 engages with the handlebar assembly 20 to prevent relative rotation, thus ensuring the handlebar assembly 20 remains stably in the unfolded state. Furthermore, it effectively eliminates the wobbling caused by assembly gaps between the handlebar assembly 20 and the base 10. Therefore, the folding handlebar of this embodiment, by engaging the backlash elimination block 31 with the handlebar assembly 20 to prevent rotation, can keep the handlebar assembly 20 stable in the unfolded state, thereby improving the user's operating experience.

[0049] In some embodiments, please refer to Figures 1 to 9 The backlash block 31 can abut against the handle assembly 20 and the base 10 respectively to achieve a non-rotational fit between the backlash block 31 and the handle assembly 20.

[0050] In other words, when the gap-eliminating block 31 is in the locked position, it continuously contacts both the handle assembly 20 and the base 10, applying pressure to both to restrict rotation of the handle assembly 20 relative to the base 10. Simultaneously, because the gap-eliminating block 31 abuts against both the handle assembly 20 and the base 10, it can fit tightly against both, thereby mitigating the problem of wobbling between the handle assembly 20 and the base 10 due to gaps and improving the operational stability of the handle assembly 20 in the unfolded state.

[0051] More preferably, please refer to Figure 5 The clearance elimination block 31 can be located on the side of the handle assembly 20 opposite to its rotation axis. Its purpose is that the fit clearance between the handle assembly 20 and the base 10 is mainly radial clearance (i.e., clearance in the direction perpendicular to the rotation axis of the handle assembly 20). By setting the clearance elimination block 31 on the side of the handle assembly 20 opposite to its rotation axis, the problem of shaking between the handle assembly 20 and the base 10 due to the fit clearance can be further alleviated.

[0052] For example, please refer to Figures 5 to 7The base 10 has two opposite sides along a first direction, namely the rider-friendly side X1 and the rider-distancing side X2. The handlebar assembly 20 is located on at least one side of the base 10 along a second direction. The rotation axis of the handlebar assembly 20 can be located on the rider-friendly side X1 of the base 10 along the first direction. That is, the handlebar assembly 20 can rotate towards the rider-friendly side X1 to reduce the space occupied by the handlebar assembly 20 in the folded state. Here, the rider-friendly side X1 refers to the side of the base 10 along the first direction that is closer to the rider (i.e., the user), and the rider-distancing side X2 refers to the side of the base 10 along the first direction that is away from the rider.

[0053] Please continue reading. Figures 5 to 7 The gap-eliminating block 31 can be located on the side of the handle assembly 20 opposite to its rotation axis along the first direction. That is, the gap-eliminating block 31 can abut against the handle assembly 20 and the base 10 on the side along the first direction respectively. This allows the gap-eliminating block 31 to fit tightly against the handle assembly 20 and the base 10, and allows the squeezing force of the gap-eliminating block 31 to act on the anti-rotation of the handle assembly 20 to the maximum extent, so as to further keep the handle assembly 20 stably in the unfolded state.

[0054] In some embodiments, please refer to Figures 1 to 3 , Figures 5 to 9 The force application component 40 may include a first force application element 41 and a transmission structure 42 that is connected to the first force application element 41 and the gap elimination structure 30 respectively. Under the action of external force, the first force application element 41 moves relative to the base 10, causing the transmission structure 42 to drive the gap elimination structure 30 to move between the locked position and the unlocked position.

[0055] The user applies a force to the first force-applying component 41, causing the first force-applying component 41 to drive the transmission structure 42 to move. The transmission structure 42, through its movement, drives the backlash-eliminating structure 30 to move between the locked and unlocked positions. This structure is convenient for user operation, and its simple structure makes it easy to maintain.

[0056] Please see Figures 5 to 7 The first force-applying component 41 can be located on the rider-side X1 of the base 10, and the gap-eliminating block 31 can be located on the rider-side of the base 10, thereby facilitating user operation of the first force-applying component 41. In other embodiments, the first force-applying component 41 can be located on the rider-side of the base 10, and the gap-eliminating block 31 can be located on the rider-side X1 of the base 10.

[0057] For example, please refer to Figures 1 to 3 , Figures 5 to 9The first force-applying component 41 can be rotatably connected to the base 10. The transmission structure 42 includes an eccentric rotating component 421 connected to the first force-applying component 41 and a transmission component 422 that is pulsatorically connected to the eccentric rotating component 421 and the backlash elimination structure 30 respectively. Under the action of external force, the first force-applying component 41 drives the eccentric rotating component 421 to rotate eccentrically around the rotation axis of the first force-applying component 41, so that the transmission component 422 drives the backlash elimination block 31 to move between the locked position and the unlocked position under the action of the eccentric rotating component 421.

[0058] Eccentric rotating component 421 refers to a rotating component whose rotation center has an eccentricity with the geometric center. Under the action of the first force-applying component 41, the eccentric rotating component 421 rotates eccentrically and, through cooperation with the transmission component 422, converts its own eccentricity into the reciprocating linear motion or oscillation of the transmission component 422. While ensuring stable transmission, the conversion of motion form can be achieved without a complex structure.

[0059] Please see Figure 8 The transmission component 422 may have a mounting hole 422a, and the eccentric rotating component 421 is rotatably disposed in the mounting hole 422a. That is, the eccentric rotating component 421 drives the transmission component 422 to move by eccentrically rotating in the mounting hole 422a. This can improve the transmission stability between the eccentric rotating component 421 and the transmission component 422 while ensuring the stable movement of the eccentric rotating component 421.

[0060] The material of the eccentric rotating component 421 is not limited. For example, the eccentric rotating component 421 can be made of stainless steel to reduce the possibility of jamming after rusting.

[0061] The type of eccentric rotating component 421 is not limited. For example, the eccentric rotating component 421 can be either an eccentric wheel or a crankshaft. That is, the eccentric rotating component 421 can be either an eccentric wheel or a crankshaft.

[0062] Taking the eccentric rotating component 421 as an example of an eccentric wheel, please refer to [link / reference]. Figures 6 to 8 The force application component 40 also includes a second rotating shaft 43 disposed on the base 10. The first force application member 41 has a first rotating hole 41a, and the eccentric wheel has an eccentrically disposed second rotating hole (not shown in the figure). The second rotating shaft 43 passes through the first rotating hole 41a and the second rotating hole, so that while the first force application member 41 rotates about the second rotating shaft 43 as the rotating axis, it drives the eccentric wheel to rotate eccentrically about the second rotating shaft 43 as the rotating axis.

[0063] Please continue reading. Figures 6 to 8The first force-applying component 41 has a first pin hole 41b, and the eccentric wheel has an eccentrically set second pin hole. The force-applying component 40 may also include an eccentric wheel pin 44, which passes through the first pin hole 41b and the second pin hole, so that the first force-applying component 41 can drive the eccentric wheel to rotate eccentrically.

[0064] In some embodiments, please refer to Figures 1 to 3 , Figure 5 and Figure 9 There are two handle assemblies 20 and two gap-eliminating structures 30. The two handle assemblies 20 can be respectively set on opposite sides of the base 10, and the gap-eliminating structures 30 correspond one-to-one with the handle assemblies 20.

[0065] In other words, one handle assembly 20 corresponds to one gap-eliminating structure 30, and each handle assembly 20 is locked by the corresponding gap-eliminating block 31. This allows for flexible configuration of the handle assembly 20 and the gap-eliminating structure 30, while also ensuring that both handle assemblies 20 can be stably kept in the unfolded state.

[0066] Please continue reading. Figure 2 , Figure 8 and Figure 9 The folding handlebar also includes a connecting rod 50 that is connected to the transmission structure 42, and two backlash-eliminating structures 30 are respectively disposed at opposite ends of the connecting rod 50. The transmission structure 42 drives the connecting rod 50 to move, which in turn causes the connecting rod 50 to move the two backlash-eliminating structures 30 between a locked position and an unlocked position.

[0067] In other words, the force-applying component 40 can simultaneously drive the two backlash-eliminating structures 30 to move via the connecting rod 50. The user only needs to operate the first force-applying component 41 to drive the two backlash-eliminating blocks 31 to move between the locked and unlocked positions, thereby simultaneously locking or unlocking the two handle assemblies 20, which can improve operating efficiency and enhance the user's operating experience.

[0068] For example, the gap-eliminating blocks 31 of the two gap-eliminating structures 30 can be connected to the connecting rod 50 respectively. In other embodiments, the two gap-eliminating blocks 31 can also be integrally formed with the connecting rod 50. That is, the two gap-eliminating blocks 31 and the connecting rod 50 are an integrally formed structure.

[0069] For an embodiment of the gap-eliminating structure 30 including the mounting base 32 and the connector 33, please refer to... Figure 9 The mounting bases 32 of the two gap-eliminating structures 30 can be connected to the connecting rod 50 respectively. In other embodiments, the two mounting bases 32 can also be integrally formed with the connecting rod 50.

[0070] In some embodiments, please refer to Figure 2 , Figure 4 and Figure 9The folding handlebars may include a guide 60 having a guide channel 60a, the guide 60 being disposed on the base 10.

[0071] The guide channel 60a is used to limit the movement trajectory of the gap-eliminating structure 30 and ensure that the gap-eliminating block 31 moves along a fixed trajectory.

[0072] For example, please refer to Figure 2 , Figure 4 and Figure 9 The gap-eliminating structure 30 includes a mounting base 32 and a connector 33. The connector 33 is connected to the mounting base 32 and the gap-eliminating block 31 respectively. The mounting base 32 is slidably disposed in the guide channel 60a. In some other embodiments, the gap-eliminating block 31 may also be slidably disposed in the guide channel 60a.

[0073] In one specific embodiment, please refer to Figure 2 , Figure 4 and Figure 9 The mounting base 32 is connected to the transmission component 422. Under the action of external force, the first force-applying component 41 drives the eccentric rotating component 421 to rotate eccentrically around the rotation axis of the first force-applying component 41. The eccentric rotating component 421 drives the transmission component 422 to move through the eccentric rotation, so that the mounting base 32 or the backlash elimination block 31 slides along the guide channel 60a under the drive of the transmission component 422. Finally, the backlash elimination block 31 moves between the locked position and the unlocked position. In other words, the eccentric rotating component 421, the transmission component 422 and the guide component 60 cooperate to convert the rotational motion of the first force-applying component 41 into the translation of the backlash elimination structure 30.

[0074] Please see Figure 5 and Figure 9 The guide channel 60a can pass through the guide member 60 in the first direction to realize the translation of the gap elimination block 31 in the first direction. That is, when the gap elimination block 31 switches from the locked position to the unlocked position, it actually moves away from the handle assembly 20 in the first direction. When the gap elimination block 31 switches from the unlocked position to the locked position, it actually moves closer to the handle assembly 20 in the first direction.

[0075] In some embodiments, please refer to Figure 4 and Figure 9 The base 10 may have a first receiving groove 10a, and when the gap elimination structure 30 is in the locked position, at least a portion of the gap elimination block 31 is located in the first receiving groove 10a.

[0076] When the gap-eliminating structure 30 moves from the unlocked position to the locked position, the gap-eliminating block 31 moves toward the first receiving groove 10a, so that at least a portion of the structure extends into the first receiving groove 10a and abuts against the groove wall of the first receiving groove 10a, thereby locking the handle assembly 20. When the gap-eliminating structure 30 moves from the locked position to the unlocked position, the gap-eliminating block 31 moves away from the first receiving groove 10a, and at least a portion of the gap-eliminating block 31 is located outside the first receiving groove 10a.

[0077] By extending at least a portion of the gap-eliminating block 31 in the locked position into the first receiving groove 10a, the flatness of the folding handle's appearance can be improved, thereby enhancing its aesthetic appeal. In addition, the first receiving groove 10a can also restrict the position of the gap-eliminating block 31, preventing the gap-eliminating block 31 from affecting the locking effect due to displacement.

[0078] Please see Figure 4 and Figure 9 The handle assembly 20 may have a second receiving groove 20a, and when the gap-eliminating structure 30 is in the unlocked position, at least a portion of the gap-eliminating block 31 is located in the second receiving groove 20a.

[0079] When the gap-eliminating structure 30 moves from the unlocked position to the locked position, the gap-eliminating block 31 moves toward the second receiving groove 20a, so that at least a portion of the structure extends into the second receiving groove 20a and abuts against the groove wall of the second receiving groove 20a, thereby locking the handle assembly 20. When the gap-eliminating structure 30 moves from the locked position to the unlocked position, the gap-eliminating block 31 moves away from the second receiving groove 20a, and at least a portion of the gap-eliminating block 31 is located outside the second receiving groove 20a.

[0080] By extending at least a portion of the gap-eliminating block 31 in the locked position into the second receiving groove 20a, the flatness of the folding handle's appearance can be improved, thereby enhancing its aesthetic appeal. In addition, the second receiving groove 20a can also restrict the position of the gap-eliminating block 31, preventing the gap-eliminating block 31 from affecting the locking effect due to displacement.

[0081] For example, please refer to Figure 4 and Figure 9The gap-eliminating block 31 includes a main body 311 and two abutting feet 312 disposed on the same side of the main body 311. The two abutting feet 312 have abutting surfaces 312a on opposite sides. From the end near the main body 311 to the end away from the main body 311, the abutting surfaces 312a of the two abutting feet 312 are inclined in a direction away from each other. When the gap-eliminating structure 30 is in the locked position, one of the two abutting feet 312 extends into the first receiving groove 10a, and the other extends into the second receiving groove 20a. Part of the sidewalls of the first receiving groove 10a and the second receiving groove 20a are in contact with the abutting surfaces 312a of each abutting foot 312 to increase the contact area between the gap-eliminating block 31 and the handle assembly 20 and the base 10 respectively. At the same time, the abutting surfaces 312a can match the direction of action of the reaction force of the handle assembly 20 and the base 10 by inclination to enhance the locking reliability.

[0082] In some embodiments, please refer to Figures 1 to 8 , Figure 10 The folding handlebar may also include a locking assembly 70, which is disposed on one of the base 10 and the handlebar assembly 20 and engages with the other locking assembly to lock the unfolded handlebar assembly 20.

[0083] The locking engagement refers to the mechanical engagement between the locking component 70 and the handle component 20 to form a constraint, so as to prevent the handle component 20 in the unfolded state from rotating relative to the base 10.

[0084] The locking component 70 can be disposed on the handle assembly 20 and lock the handle assembly 20 by locking it with the base 10. Alternatively, the locking component 70 can also be disposed on the base 10 and lock it with the handle assembly 20. That is to say, when the handle assembly 20 is in the unfolded state, not only can the backlash-eliminating block 31 engage with the handle assembly 20 to prevent rotation and keep the handle assembly 20 in the unfolded state, but the locking component 70 can also lock the unfolded handle assembly 20, thereby keeping the handle assembly 20 in the unfolded state, which can further improve the stability of the handle assembly 20 in the unfolded state.

[0085] The structure of the locking component 70 is not limited; for example, please refer to [link to relevant documentation]. Figures 1 to 8 , Figure 10 The locking assembly 70 may include a pin 71 retractably disposed in one of the base 10 and the handle assembly 20, the other of the base 10 and the handle assembly 20 having a locking groove 10b, the pin 71 extending into the locking groove 10b to lock the extended handle assembly 20.

[0086] Figures 1 to 8 , Figure 10The latch 71 is retractably disposed on the handle assembly 20, and the base 10 has a locking groove 10b. That is, the latch 71 can extend relative to the handle assembly 20 to enter the locking groove 10b on the base 10, thereby forming a rotational constraint on the handle assembly 20 in the unfolded state and restricting the relative rotation of the handle assembly 20. When the latch 71 retracts into the handle assembly 20, the latch 71 can disengage from the locking groove 10b to release the locking engagement, allowing the handle assembly 20 to transition to the folded state. In other embodiments, the latch 71 may also be disposed on the base 10, and the handle assembly 20 may have a locking groove 10b.

[0087] The engagement between the pin 71 and the locking groove 10b is highly reliable and can withstand large operating loads, thereby further improving the stability of the handle assembly 20 in the unfolded state.

[0088] Please see Figure 10 One of the base 10 and the handle assembly 20 may have a mounting groove 20b, and a locking groove 10b is provided in the other of the base 10 and the handle assembly 20. The mounting groove 20b communicates with the locking groove 10b. A pin 71 is slidably disposed in the mounting groove 20b, and a portion of the structure of the pin 71 can extend into the locking groove 10b from the communication between the mounting groove 20b and the locking groove 10b.

[0089] The mounting groove 20b can restrict the movement direction of the pin 71. That is, when the pin 71 slides in the mounting groove 20b, it can accurately extend into the locking groove 10b or disengage from the locking groove 10b, thereby improving the user's operating experience.

[0090] Please continue reading. Figure 10 The locking assembly 70 may also include an elastic reset member 72 and a second force-applying member 73 connected to the pin 71. The elastic reset member 72 abuts against the pin 71 and the groove wall of the mounting groove 20b respectively. The second force-applying member 73 is located outside the mounting groove 20b. Under the elastic force of the elastic reset member 72, the pin 71 extends into the locking groove 10b. Under the action of external force, the second force-applying member 73 drives the pin 71 to disengage from the locking groove 10b, thereby unlocking the locking assembly 70.

[0091] The elastic reset member 72 applies a force to the pin 71, causing the pin 71 to tend to extend into the locking groove 10b. That is, the opposite ends of the elastic reset member 72 along the extension / contraction direction abut against the pin 71 and the groove wall of the mounting groove 20b, respectively, allowing the pin 71 to slide within the mounting groove 20b through its own elastic extension and contraction. When the second force-applying member 73, under the action of an external force, causes the pin 71 to disengage from the locking groove 10b, the pin 71 causes the elastic reset member 72 to contract and deform, storing elastic potential energy. When the external force is removed, the elastic reset member 72 releases this elastic potential energy, causing the pin 71 to extend into the locking groove 10b. This achieves automatic locking of the pin 71, improving user convenience.

[0092] Preferably, in order to keep the pin 71 more stably in the position of extending into the locking groove 10b, when the pin 71 is in the extreme position of extending into the locking groove 10b, the elastic reset member 72 is still in a compressed state. That is to say, the elastic reset member 72 always applies a force to the pin 71 to move the pin 71 away from the mounting groove 20b and into the locking groove 10b.

[0093] The type of elastic reset element 72 is not limited; please refer to [link / reference]. Figure 10 The elastic reset element 72 can be a spring.

[0094] In other embodiments, the locking assembly 70 may also include a second force-applying member 73, an elastic tension member, and hooks connected to the second force-applying member 73 and the elastic tension member respectively. The end of the elastic tension member away from the hook is connected to one of the base 10 and the handle assembly 20. Under the action of an external force, the second force-applying member 73 drives the hook to engage with the other one.

[0095] In other words, when the handle assembly 20 is in the unfolded state, the user can use the second force-applying member 73 to drive the hook to hook the base 10 or the handle assembly 20. At this time, the elastic tension member remains in the stretched state to always apply a pulling force to the base 10 and the handle assembly 20, so that the handle assembly 20 is stably kept in the unfolded state. Moreover, if the handle assembly 20 needs to switch from the unfolded state to the folded state, the second force-applying member 73 can be used to disengage the hook from the base 10 or the handle assembly 20, so that the handle assembly 20 can rotate relative to the base 10.

[0096] The hook and elastic tension member have a simple structure and low maintenance cost. Moreover, the elastic tension member can further eliminate the shaking of the handle assembly 20 by absorbing the radial vibration of the handle assembly 20.
