Description

Technical Field

[0001] This utility model relates to the field of bicycle handlebar technology, specifically a handlebar locking structure for shared bicycles. Background Technology

[0002] Shared bicycles, as a convenient and environmentally friendly mode of transportation, have been well received by a wide range of users.

[0003] When scheduling or parking shared bikes, in order to save space, the spacing between shared bikes is usually very small. Furthermore, if a shared bike at the edge is damaged, the user needs to pull out the shared bike in the middle to use it. Since the existing shared bikes do not have a handlebar return and locking function, it is difficult to move the shared bikes arranged in the middle, which affects the user experience. Utility Model Content

[0004] The purpose of this invention is to provide a handlebar locking structure for shared bicycles to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a handlebar locking structure for a shared bicycle, including a frame, a stem rotatably connected to the frame, a limiting protrusion provided on the side wall of the stem, an annular groove provided on the frame to cooperate with the limiting protrusion, and an arc-shaped block slidably connected in the annular groove, wherein the arc-shaped block can push the limiting protrusion to return the stem to its upright position when it slides.

[0006] As a further preferred embodiment of this technical solution, there are two limiting protrusions and two arc-shaped blocks. The two limiting protrusions are symmetrically arranged on both sides of the handlebar, and the two arc-shaped blocks slide symmetrically in the annular groove. The two arc-shaped blocks can slide synchronously to approach the two limiting protrusions respectively.

[0007] As a further preferred embodiment of this technical solution, a passive hydraulic cylinder is fixedly connected inside the frame, and a first connecting rod is fixedly connected to the output end of the passive hydraulic cylinder. A hinge seat is fixedly connected to the output end of the first connecting rod, and two second connecting rods are symmetrically hinged to the hinge seat. The ends of the two second connecting rods are respectively hinged to the two arc-shaped blocks.

[0008] As a further preferred embodiment of this technical solution, a seat post is connected to the frame, and a seat is connected to the seat post.

[0009] As a further preferred embodiment of this technical solution, a baffle is fixedly connected to the bottom of the seat, and a hook is slidably connected to the seat between the baffle and the seat post. An active hydraulic cylinder is connected between the hook and the baffle, and an oil pipe connects the active hydraulic cylinder and the passive hydraulic cylinder.

[0010] As a further preferred embodiment of this technical solution, the active cylinder includes a piston cylinder and a piston rod that slides within the piston cylinder, and a spring connects the hook and the baffle.

[0011] As a further preferred embodiment of this technical solution, the upper part of the stem is connected to the handlebar body, and the lower part of the stem is connected to the fork.

[0012] This utility model provides a handlebar locking structure for shared bicycles, which has the following advantages:

[0013] A handlebar locking structure for a shared bicycle includes a frame, a stem rotatably connected to the frame, a limiting protrusion on the side wall of the stem, an annular groove on the frame that mates with the limiting protrusion, and an arc-shaped block slidably connected within the annular groove. When the arc-shaped block slides, it can push the limiting protrusion to return the stem to its upright position.

[0014] When shared bikes are packed tightly together and difficult to move, the control arc block slides in the annular groove, causing the arc block to abut against the limiting protrusion on the handlebar, pushing the handlebar to the upright position. At this time, the front wheel of the bike faces forward, making it easier to pull the shared bike out of the tight arrangement when pulling it from behind. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Reference Figures 1-4 This utility model provides a technical solution: a handlebar locking structure for a shared bicycle, including a frame 100, a handlebar stem 120 rotatably connected to the frame 100, a limiting protrusion 250 provided on the side wall of the handlebar stem 120, an annular groove 251 provided on the frame 100 to cooperate with the limiting protrusion 250, and an arc-shaped block 240 slidably connected in the annular groove 251. When the arc-shaped block 240 slides, it can push the limiting protrusion 250 to make the handlebar stem 120 return to the center position.

[0022] When shared bicycles are tightly packed and difficult to move, the control arc block 240 slides within the annular groove 251, causing the arc block 240 to abut against the limiting protrusion 250 on the handlebar 120, pushing the handlebar 120 to the upright state. At this time, the front wheel of the bicycle faces forward, making it easier to pull the shared bicycle out of the tight arrangement when pulling it from behind.

[0023] The number of the limiting protrusion 250 and the number of the arc-shaped block 240 are both two. The two limiting protrusions 250 are symmetrically arranged on both sides of the handlebar 120. The two arc-shaped blocks 240 slide symmetrically in the annular groove 251, and the two arc-shaped blocks 240 can slide synchronously to approach the two limiting protrusions 250 respectively.

[0024] The two arc-shaped blocks 240 move synchronously and at equal distances, approaching the corresponding limiting protrusions 250. When the stem 120 is not in the centered state, one of the arc-shaped blocks 240 can first approach the limiting protrusions 250, thereby pushing the stem 120 to rotate towards the centered state. When the two arc-shaped blocks 240 respectively abut against the corresponding limiting protrusions 250, the stem 120 is in the centered state.

[0025] A passive hydraulic cylinder 200 is fixedly connected inside the frame 100. A first connecting rod 210 is fixedly connected to the output end of the passive hydraulic cylinder 200. A hinge seat 220 is fixedly connected to the output end of the first connecting rod 210. Two second connecting rods 230 are symmetrically hinged on the hinge seat 220. The ends of the two second connecting rods 230 are respectively hinged to the two arc-shaped blocks 240.

[0026] When the passive cylinder 200 extends, it can drive the first link 210 to slide towards the stem 120. At this time, the angle between the two second links 230 and the opening of the stem 120 increases. After being pushed by the first link 210, the second link 230 is transmitted to the corresponding arc block 240, which in turn causes the arc block 240 to slide and push the limiting protrusion 250. When the passive cylinder 200 shortens, the angle between the two second links 230 decreases, and at the same time, it pulls the two arc blocks 240 to slide away from the corresponding limiting protrusion 250, ensuring that the rotation of the stem 120 is not interfered with during normal driving.

[0027] A seat post 140 is connected to the frame 100, and a seat 150 is connected to the seat post 140.

[0028] The 150 seat height is adjustable to suit the rider's needs, ensuring both riding comfort and safety.

[0029] A baffle 340 is fixedly connected to the bottom of the seat 150. A hook 300 is slidably connected on the seat 150 between the baffle 340 and the seat post 140. An active hydraulic cylinder is connected between the hook 300 and the baffle 340. An oil pipe 320 connects the active hydraulic cylinder and the passive hydraulic cylinder 200.

[0030] When it is necessary to move bicycles out of a closely spaced area that is not at the edge, manually pull the hook 300. The hook 300 will move closer to the baffle 340. At this time, the active cylinder between the two will compress, and the hydraulic pressure in the oil pipe 320 will be transmitted to the passive cylinder 200, thereby extending the passive cylinder 200. This will drive the first connecting rod 210 to slide, and the included angle of the second connecting rod 230 will increase. The arc block 240 will push the limit protrusion 250, realizing the return of the stem 120 to the center, ensuring that the bicycle can be moved out smoothly. After the hook 300 resets, the active cylinder will return to its original state, and the hydraulic pressure will flow back to the passive cylinder 200, causing it to shorten. The included angle of the second connecting rod 230 will decrease, and the arc block 240 will move away from the limit protrusion 250, returning to the initial state, ensuring that the bicycle can be used normally.

[0031] The active cylinder includes a piston cylinder 310 and a piston rod 350 that slides within the piston cylinder 310. A spring 330 is connected between the hook frame 300 and the baffle 340.

[0032] The passive cylinder 200 is located inside the frame 100. The oil pipe passes through the frame 100 and is connected to the passive cylinder 200. The spring 330 provides a reverse elastic force when the active cylinder is compressed, ensuring that the hook 300 returns to its original position quickly. The piston rod 350 is equipped with a sealing ring to prevent hydraulic oil leakage and improve system stability. The oil pipe 320 is made of high-pressure resistant material to ensure efficient and reliable hydraulic transmission. The overall design is compact and easy to operate, greatly improving the convenience and safety of moving the bicycle out. In addition, the baffle 340 can also be removed from the seat 150, thereby separating the piston rod 350 from the piston cylinder 310, which facilitates the replenishment and replacement of hydraulic oil later.

[0033] The upper part of the stem 120 is connected to the handlebar body 110, and the lower part of the stem 120 is connected to the fork 130.

[0034] The front fork 130 is connected to the frame 100 via a steering bearing (not shown in the figure), and the handlebars 110 are also equipped with grips and brakes (not shown in the figure) for easy control by the rider.

[0035] This utility model provides a handlebar locking structure for shared bicycles, and its specific working principle is as follows:

[0036] When shared bicycles are closely arranged, the rider can manually move the hook 300 closer to the baffle 340. At this time, the active cylinder is compressed, and hydraulic pressure is transmitted to the passive cylinder 200 through the oil pipe 320. The passive cylinder 200 extends, pushing the first connecting rod 210 to slide towards the stem 120. Then, through the transmission of the second connecting rod 230, the arc-shaped block 240 slides within the annular groove 251. During the sliding process, the arc-shaped block 240 abuts against and pushes the limiting protrusion 250, and the limiting protrusion 250 is subjected to the arc. The thrust of the block 240 drives the stem 120 to rotate towards the center position until the stem 120 is fully centered. At this time, the front wheel of the bicycle faces forward, making it easier for the rider to move out of the tightly packed bicycle. After the hook 300 is reset, the active cylinder returns to its original position, and the hydraulic pressure flows back to the passive cylinder 200. The passive cylinder 200 shortens, and through the linkage, the arc block 240 slides away from the limit protrusion 250, returning to the initial state. At this time, the stem 120 can rotate normally, meeting the rider's control needs.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
