Description

Technical Field

[0001] This utility model relates to the field of bicycle accessories technology, specifically a bicycle handlebar with a split, rotating, and folding cross tube. Background Technology

[0002] With increasing global environmental awareness, green travel options are gaining popularity, and bicycles, as an environmentally friendly and healthy mode of transportation, are experiencing rising market demand year by year. Handlebars, as the control mechanism for bicycle direction, are often inconvenient to fold due to limited urban living space. Ordinary bicycle handlebars are either not foldable or inconvenient to fold, taking up considerable space for storage and transport, causing problems for parking and moving.

[0003] According to Chinese Patent CN220595099U, a handlebar assembly for a folding bicycle includes a first support rod, a second support rod slidably connected to the inner wall of the first support rod, and multiple positioning holes on the surface of the second support rod. A first bolt is rotatably connected to the front end of the first support rod. This invention designs a hinge shaft and handlebars that cooperate. When folding is required, rotating the third bolt loosens the support plate, and then rotating the two handlebars retracts them into the inner wall of the arc-shaped clamp for fixation, allowing the handlebars to fold as well, further reducing the space occupied by the bicycle after folding. At the same time, the cooperation between the first bolt and the second support rod allows for flexible adjustment of the handlebar height, improving the product's applicability. An inflatable layer and a sponge layer are designed to effectively absorb shock when passing through areas with significant vibration, making it easier for the rider to grip and improving riding safety.

[0004] The aforementioned devices primarily rely on bolt tightening for fixation, which may loosen more easily under significant external forces, affecting riding safety. Therefore, we provide a rotating folding handlebar with a split center section in the handlebar tube. Utility Model Content

[0005] The purpose of this invention is to provide a bicycle handlebar that splits in the middle of the handlebar tube and rotates and folds, in order to solve the problems mentioned in the background art.

[0009] And an operating assembly fixedly connected between the frame and the connecting rod; the operating assembly includes a folding portion fixedly connected between the frame and the connecting rod, the folding portion being connected to a reinforcing portion.

[0010] Preferably, the folding part includes a mounting tube fixedly sleeved on the outer wall of the side end of the connecting rod. The inner surface of the side end of the mounting tube is threaded through the left end of the docking rod via a threaded groove. The threaded groove is formed on the outer wall of the left end of the docking rod. A handle is fixedly connected to the right side of the docking rod. An annular groove is formed on the outer wall of the docking rod. An annular protrusion is engaged on the inner surface of the annular groove. An L-shaped rod is fixedly connected to the bottom of the annular protrusion. The left side of the bottom end of the L-shaped rod passes through the right side of the outer tube and is fixedly connected to the inner surface of the outer tube via a connecting spring. The left end of the outer tube is hinged to the surface of the mounting bracket. The left side of the mounting bracket is fixedly connected to the outer wall of the vehicle frame.

[0011] Preferably, the reinforcing part includes a reinforcing rod fixedly connected to the left side of the inner end of the connecting rod. The end of the reinforcing rod away from the connecting rod is inserted into the inner surface of the movable groove. The movable groove is opened on the side of the connecting rod. An extension groove is opened on the inner surface of the movable groove. A reinforcing groove is opened on the outer wall of one end of the reinforcing rod that extends through the extension groove. A reinforcing block is snapped into the inner surface of the reinforcing groove. An adjusting rod is fixedly connected to the top of the reinforcing block. The bottom of the adjusting rod passes through the outer wall of the guide rod. The upper and lower ends of the guide rod are respectively fixedly connected to the inner surface of the extension groove. A reinforcing elastic sheet passes through the outer wall of the guide rod. The convex surface of the reinforcing elastic sheet is fixedly connected to the bottom of the adjusting rod. A reinforcing spring is fixedly connected to the concave surface of the elastic sheet.

[0012] Preferably, the inner surface of the annular protrusion and the inner surface of the annular groove are configured to be rotatably connected, so that the connecting rod and the mounting tube can rotate flexibly to realize the rotation and folding of the handlebar.

[0013] Preferably, the outer surface of the bottom end of the L-shaped rod is configured to slide through the inner surface of the outer tube, so that the L-shaped rod can slide smoothly inside the outer tube during the operation of folding and unfolding the handlebars.

[0014] Preferably, the outer wall of the guide rod and the bottom of the adjusting rod are configured to slide through each other, so that the adjusting rod can move accurately along the direction of the guide rod during operation.

[0015] Preferably, the number of the reinforcing elastic plates is set to two. The two reinforcing elastic plates are respectively fixed through the outer wall of the guide rod and are arranged symmetrically from top to bottom. The two reinforcing elastic plates are fixedly connected by a reinforcing spring, which further enhances the stability and durability of the handlebar structure.

[0016] Compared with the prior art, this utility model provides a bicycle handlebar with a split cross tube that rotates and folds, which has the following advantages:

[0017] This bicycle handlebar features a split, rotating folding design. The mounting tube and connecting rod are threaded together via a groove, allowing for easy screwing of the connecting rod into or out of the mounting tube. This enables quick disassembly and assembly of the handlebar. When storing the bicycle, the handlebar can be conveniently folded for easy storage and transport. The connecting rod's outer wall features a ring groove and a ring protrusion for rotatable connection. The L-shaped rod provides stable guidance for the connecting rod's movement when it is screwed into or out of the mounting tube, and the spring force ensures a stable connection during normal use, preventing easy wobbling.

[0018] The handlebars are designed to be rotated and folded in the middle of the cross tube. A connecting rod drives a reinforcing rod into a movable slot. The inner end of the reinforcing rod then contacts a reinforcing block, causing the reinforcing block to slide along the outer wall of the guide rod. When the reinforcing slot aligns with the reinforcing block, the elasticity of the reinforcing sheet and spring causes the reinforcing block to engage in the reinforcing slot, thus strengthening the connection between the connecting rod and the connecting rod. During riding, the handlebars can withstand greater external forces without easily loosening or deforming. The adjusting rod controls the engagement and disengagement of the reinforcing block, allowing for convenient adjustment and maintenance of the handlebars. When repairs or replacements are needed, simply rotate the connecting rod to disengage the reinforcing block from the reinforcing slot, easily removing the connecting rod and improving maintenance efficiency. Furthermore, when the handlebars are subjected to sudden impacts, the reinforcing sheet and spring absorb some energy, reducing damage to the handlebar structure, extending the handlebar's lifespan, and improving riding comfort.

[0028] Example 1: The handlebar cross tube of this utility model is split in the middle and rotates to fold. (Example:) Figures 1 to 6 As shown: A bicycle handlebar with a split center section for rotation and folding, comprising: a connector 1;

[0029] The frame 2 is fixedly connected to the bottom of the connector 1;

[0030] A connecting rod 3 is fixedly inserted through the side of connector 1;

[0031] And an operating component 4 fixedly connected between the frame 2 and the connecting rod 3; the operating component 4 includes a folding part 41 fixedly connected between the frame 2 and the connecting rod 3, and the folding part 41 is connected to a reinforcing part 42.

[0032] The folding part 41 includes a mounting tube 411 fixedly sleeved on the outer wall of the side end of the connecting rod 3. The inner surface of the side end of the mounting tube 411 is threaded through the left end of the docking rod 412 via a threaded groove 413. The threaded groove 413 is opened on the outer wall of the left end of the docking rod 412. A handle 414 is fixedly connected to the right side of the docking rod 412. An annular groove 415 is opened on the outer wall of the docking rod 412. An annular protrusion 416 is engaged on the inner surface of the annular groove 415. An L-shaped rod 417 is fixedly connected to the bottom of the annular protrusion 416. The left side of the bottom end of the L-shaped rod 417 passes through the right side of the outer tube 419 and is fixedly connected to the inner surface of the outer tube 419 via a connecting spring 418. The left end of the outer tube 419 is hinged to the surface of the mounting bracket 410. The left side of the mounting bracket 410 is fixedly connected to the outer wall of the frame 2.

[0033] In this embodiment, the inner surface of the annular protrusion 416 and the inner surface of the annular groove 415 are configured to be rotatably connected, so that the connecting rod 412 and the mounting tube 411 can rotate flexibly to realize the rotation and folding of the handlebar.

[0034] Furthermore, the outer surface of the bottom end of the L-shaped rod 417 is designed to slide through the inner surface of the outer tube 419, so that the L-shaped rod 417 can slide smoothly inside the outer tube 419 during the operation of folding and unfolding the handlebars.

[0035] Example 2: Based on Example 1, the bicycle handlebars provided by this utility model are split and rotated folding handlebars, such as... Figures 1 to 6 As shown: The reinforcing part 42 includes a reinforcing rod 421 fixedly connected to the left side of the inner end of the connecting rod 412. The end of the reinforcing rod 421 away from the connecting rod 412 is inserted into the inner surface of the movable groove 422. The movable groove 422 is opened on the side of the connecting rod 3. An extension groove 423 is opened on the inner surface of the movable groove 422. A reinforcing groove 424 is opened on the outer wall of one end of the reinforcing rod 421 that extends through the extension groove 423. A reinforcing block 425 is snapped into the inner surface of the reinforcing groove 424. An adjusting rod 426 is fixedly connected to the top of the reinforcing block 425. The bottom of the adjusting rod 426 passes through the outer wall of the guide rod 427. The upper and lower ends of the guide rod 427 are fixedly connected to the inner surface of the extension groove 4236, respectively. A reinforcing elastic sheet 428 passes through the outer wall of the guide rod 427. The convex surface of the reinforcing elastic sheet 428 is fixedly connected to the bottom of the adjusting rod 426. A reinforcing spring 429 is fixedly connected to the concave surface of the elastic sheet 428.

[0036] In this embodiment, the outer wall of the guide rod 427 and the bottom of the adjusting rod 426 are configured to slide through each other, so that the adjusting rod 426 can move accurately along the direction of the guide rod 427 during operation.

[0037] Furthermore, the number of reinforcing elastic plates 428 is set to two. The two reinforcing elastic plates 428 are fixedly inserted through the outer wall of the guide rod 427 and are arranged symmetrically from top to bottom. The two reinforcing elastic plates 428 are fixedly connected by reinforcing springs 429, which further enhances the stability and durability of the handlebar structure.

[0038] In actual operation, when this device is used, the mounting tube 411 and the connecting rod 412 are threaded through the threaded groove 413, and the connecting rod 412 can be easily screwed into or out of the mounting tube 411, realizing the quick disassembly and assembly of the handlebars, and making the handlebars easy to fold. At the same time, the annular groove 415 and the annular protrusion 416 on the outer wall of the connecting rod 412 are rotatably connected. When the connecting rod 412 is screwed into or out of the mounting tube 411, the L-shaped rod 417 provides stable guidance for the movement of the connecting rod 412, and the elasticity of the connecting spring 418 ensures that the handlebars are firmly connected during normal use and will not easily wobble.

[0039] The connecting rod 412 drives the reinforcing rod 421 to insert into the movable groove 422. At this time, the inner end of the reinforcing rod 421 abuts against the reinforcing block 425, causing the reinforcing block 425 to drive the adjusting rod 426 to slide on the outer wall of the guide rod 427. When the reinforcing groove 424 and the reinforcing block 425 are aligned, the elastic force of the reinforcing elastic sheet 428 and the reinforcing spring 429 causes the reinforcing block 425 to be engaged in the reinforcing groove 424, thereby enhancing the connection strength between the connecting rod 412 and the connecting rod 3. During riding, the handlebars can withstand greater external forces and will not easily loosen or... The handlebars can be easily adjusted and maintained by adjusting the rod 416 to control the insertion and release of the reinforcing block 425. When the handlebars need to be repaired or parts replaced, simply rotate the connecting rod 412 to squeeze the reinforcing block 425 out of the reinforcing groove 424, and the connecting rod 412 can be easily removed, improving maintenance efficiency. At the same time, when the handlebars are subjected to sudden impact, the reinforcing elastic plate 428 and the reinforcing spring 429 can absorb some of the energy, reduce damage to the handlebar structure, extend the service life of the handlebars, and improve riding comfort.
