Description

Technical Field

[0001] This utility model relates to the field of shared bicycle technology, specifically a structure for preventing shared bicycles from being forgotten. Background Technology

[0002] With the booming development of the sharing economy, shared bicycles have become an important choice for citizens' short-distance travel due to their convenience and environmental friendliness. However, in daily use, users often carelessly leave their belongings in the baskets of shared bicycles after riding, resulting in personal property loss and increasing the difficulty of finding and managing these items.

[0003] Currently, most shared bicycles on the market focus on technological improvements in areas such as anti-theft, GPS tracking, and riding comfort, while designs to prevent users from forgetting items in the baskets are relatively lacking. The few devices with reminder functions rely solely on voice prompts, which are ineffective in drawing users' attention. Utility Model Content

[0004] The purpose of this invention is to provide a structure to prevent shared bicycles from being forgotten, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a shared bicycle anti-forgotten structure, including a bicycle body, a bicycle basket connected to the bicycle body, a mounting frame fixedly connected to the bicycle basket, a hollow cylinder fixedly connected to the mounting frame, a protrusion provided on the inner wall of the hollow cylinder, a rotating shaft coaxially rotatably connected to the middle of the hollow cylinder, a connecting rod hinged to the side wall of the rotating shaft, a striking ball fixedly connected to the end of the connecting rod, a foot support provided on the bicycle body, when the foot support falls, the rotating shaft rotates inside the hollow cylinder, thereby the striking ball is driven by centrifugal force to swing the connecting rod upward, so that the striking ball hits the protrusion, thereby making the hollow cylinder produce sound.

[0006] As a further preferred embodiment of this technical solution, multiple striking balls and multiple protrusions are provided. The multiple striking balls are arranged in a ring array on the side wall of the rotating shaft, and the multiple protrusions are arranged in a ring array on the inner wall of the hollow cylinder. The multiple striking balls can alternately strike the multiple protrusions, so that the hollow cylinder can continuously produce sound.

[0007] As a further preferred embodiment of this technical solution, a small gear is fixedly connected to the bottom of the rotating shaft, an mounting ring is fixedly connected to the basket, a rotating cylinder is rotatably connected to the middle of the mounting ring, a rotating rod is coaxially rotatably connected to the middle of the rotating cylinder, a large gear meshing with the small gear is fixedly connected to the top of the rotating rod, a torsion spring is fixedly connected between the rotating rod and the inner wall of the rotating cylinder, and a pull rope is connected between the foot support and the outer wall of the rotating cylinder. The pull rope is wound around the rotating cylinder. When the foot support falls, the pull rope is released from the rotating cylinder, thereby driving the torsion spring to deform. The torsion spring returns to its original shape and drives the rotating rod to rotate.

[0008] As a further preferred embodiment of this technical solution, a basket cover is hinged to the basket, a lever is fixedly connected to the lower surface of the basket cover, a rack is slidably connected through the basket, the lever can abut against the rack, and a storage gear is rotatably connected to the rotating drum via a one-way bearing. The storage gear meshes with the rack, and when the basket cover is opened or closed, it can drive the rack to slide first towards the basket and then away from the basket. Thus, the rack drives the storage gear to rotate relative to the rotating drum first, and then drives the rotating drum to rotate synchronously to store the pull rope.

[0009] As a further preferred embodiment of this technical solution, a tension spring is fixedly connected between the end of the rack away from the basket and the vehicle body.

[0010] As a further preferred embodiment of this technical solution, a one-way bearing is connected between the rotating rod and the large gear. When the rotating drum rotates and houses the pull rope, the rotating rod rotates relative to the large gear.

[0011] This utility model provides a structure to prevent shared bicycles from being forgotten, which has the following beneficial effects:

[0012] This invention utilizes the interplay of a rotating shaft, connecting rod, striking ball, protrusion, small gear, large gear, rotating cylinder, torsion spring, and pull rope to enable the rotating cylinder to rotate via the pull rope when the footrest is lowered. The rotating cylinder then drives the rotating rod and large gear to rotate via the torsion spring. The large gear in turn drives the small gear and rotating shaft to rotate, which in turn causes the connecting rod to swing the striking ball and strike the protrusion, thus producing a sound from the hollow cylinder to remind the user and effectively prevent the user from forgetting items.

Detailed Implementation

[0019] 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.

[0020] Reference Figures 1-5 The present invention provides the following technical solution: In this embodiment, a shared bicycle anti-forgotten structure includes a bicycle body 100, a bicycle basket 200 connected to the bicycle body 100, a mounting frame 230 fixedly connected to the bicycle basket 200, a hollow cylinder 240 fixedly connected to the mounting frame 230, a protrusion 241 provided on the inner wall of the hollow cylinder 240, a rotating shaft 250 coaxially rotatably connected to the middle of the hollow cylinder 240, a connecting rod 251 hinged to the side wall of the rotating shaft 250, a striking ball 252 fixedly connected to the end of the connecting rod 251, and a foot support 110 provided on the bicycle body 100. When the foot support 110 falls, the rotating shaft 250 rotates inside the hollow cylinder 240, thereby causing the striking ball 252 to be driven by centrifugal force to swing the connecting rod 251 upward, so that the striking ball 252 hits the protrusion 241, thereby making the hollow cylinder 240 make a sound.

[0021] When the ride ends, the footrest 110 is lowered. At this time, the footrest 110 drives the shaft 250 to rotate rapidly. When the shaft 250 rotates rapidly, the striking ball 252 continuously hits the protrusion 241 under the action of centrifugal force, making a crisp sound, reminding the user to check whether there are any items left in the basket 200, effectively preventing forgetting. The hollow cylinder 240 is made of metal material. When the striking ball 252 hits the metal hollow cylinder 240, the hollow cylinder 240 vibrates and makes a sound.

[0022] Multiple striking balls 252 and multiple protrusions 241 are provided. Multiple striking balls 252 are arranged in a ring array on the side wall of the rotating shaft 250, and multiple protrusions 241 are arranged in a ring array on the inner wall of the hollow cylinder 240. Multiple striking balls 252 can alternately strike multiple protrusions 241, so that the hollow cylinder 240 can continuously produce sound.

[0023] The design incorporating multiple striking balls 252 and raised bumps 241 ensures the continuity and clarity of the sound, effectively enhancing the reminder effect.

[0024] A small gear 260 is fixedly connected to the bottom of the rotating shaft 250. An installation ring 300 is fixedly connected to the basket 200. A rotating cylinder 310 is rotatably connected to the middle of the installation ring 300. A rotating rod 320 is coaxially rotatably connected to the middle of the rotating cylinder 310. A large gear 340 that meshes with the small gear 260 is fixedly connected to the top of the rotating rod 320. A torsion spring 330 is fixedly connected between the rotating rod 320 and the inner wall of the rotating cylinder 310. A pull rope 120 is connected between the foot support 110 and the outer wall of the rotating cylinder 310. The pull rope 120 is wound around the rotating cylinder 310. When the foot support 110 falls, the pull rope 120 is released from the rotating cylinder 310, thereby driving the rotating cylinder 310 to deform the torsion spring 330. The torsion spring 330 returns to its original shape and drives the rotating rod 320 to rotate.

[0025] The rotation of the lever 320 drives the large gear 340 to rotate, which in turn drives the small gear 260 to rotate. Since the large gear 340 has far more teeth than the small gear 260, the small gear 260 rotates faster, further accelerating the rotation of the shaft 250. This increases the frequency of the striking ball 252 hitting the protrusion 241, making the sound louder and longer, ensuring that the user can hear the reminder even in noisy environments. When the footrest 110 is lowered, the pull rope 120 pulls the rotating cylinder 310 to rotate around the mounting ring 300. Since the small gear 260 initially resists the large gear 340, the rotating cylinder 310 can rotate relative to the lever 320 first, causing the torsion spring 330 to be tightened. Subsequently, the torsion spring 330 slowly and continuously releases potential energy, so that the user can hear a crisp reminder sound after parking, ensuring that no items in the basket 200 are left behind.

[0026] A blue cover 210 is hinged to the basket 200. A lever 211 is fixedly connected to the lower surface of the blue cover 210. A rack 360 is slidably connected through the basket 200. The lever 211 can abut against the rack 360. A storage gear 350 is rotatably connected to the rotating drum 310 through a one-way bearing. The storage gear 350 meshes with the rack 360. When the blue cover 210 is opened or closed, it can drive the rack 360 to slide towards the basket 200 first, and then slide away from the basket 200. Thus, the rack 360 drives the storage gear 350 to rotate relative to the rotating drum 310 first, and then drives the rotating drum 310 to rotate synchronously to store the pull rope 120.

[0027] When placing items, the user needs to open the blue cover 210 first and then close it. The blue cover 210 drives the lever 211 to press and release the rack 360, allowing the rack 360 to slide back and forth. When the blue cover 210 is opened, the lever 211 first moves away from the rack 360, and the rack 360 drives the storage gear 350 to rotate. The one-way bearing between the storage gear 350 and the rotating drum 310 allows the storage gear 350 to rotate relative to the rotating drum 310. When the blue cover 210 is closed, the lever 211 pushes the rack 360 to slide. At this time, the rack 360 drives the storage gear 350 to drive the rotating drum 310 to rotate synchronously. At this time, the rotating drum 310 stores the pull rope 120, so that when the foot support 110 falls, it can pull the pull rope 120 and release it to the rotating drum 310, at which point the rotating drum 310 rotates again.

[0028] That is, for the hollow tube 240 to make a sound, the blue cover 210 needs to be opened and then closed before it can be triggered by the falling of the foot support 110.

[0029] A tension spring 370 is fixedly connected between the end of the rack 360 away from the basket 200 and the vehicle body 100.

[0030] The tension spring 370 applies tension to the rack 360, so that when the lever 211 moves away from the rack 360, the tension spring 370 can drive the rack 360 to slide, thereby causing the receiving gear 350 to rotate relative to the rotating drum 310.

[0031] A one-way bearing is connected between the rotating rod 320 and the large gear 340. When the rotating drum 310 rotates and takes in the pull rope 120, the rotating rod 320 rotates relative to the large gear 340.

[0032] The one-way bearing between the rotating rod 320 and the large gear 340 allows the rotating drum 310 to rotate synchronously when the receiving gear 350 drives it. The rotating drum 310 transmits power to the rotating rod 320, enabling the rotating rod 320 to rotate relative to the large gear 340, thus reducing the sliding resistance of the rack 360.

[0033] This utility model provides a structure to prevent shared bicycles from being forgotten, and its specific working principle is as follows:

[0034] When a user arrives at their destination on a shared bicycle and prepares to park, they need to lower the kickstand 110 to support the bicycle body 100. At this time, the pull rope 120 between the kickstand 110 and the outer wall of the rotating drum 310 is released, and the rotating drum 310 begins to rotate under the action of the torsion spring 330. The rotation of the rotating drum 310 drives the rotating shaft 250 to rotate rapidly through the meshing relationship between the large gear 340 and the small gear 260 on the rotating rod 320. Under the action of centrifugal force, the striking ball 252 on the rotating shaft 250 continuously strikes the protrusion 241 on the inner wall of the hollow cylinder 240, thus producing a crisp sound. This design can effectively remind the user to check whether there are any items left in the basket 200, preventing... The design avoids forgetting, and because there are multiple striking balls 252 and protrusions 241 arranged in a circular array, the continuity and clarity of the sound are ensured, further enhancing the reminder effect. In addition, when the user needs to place or take out an item, the blue cover 210 needs to be opened and closed. This action drives the rack 360 to slide, and through the meshing relationship between the storage gear 350 and the rotating drum 310, the pull rope 120 is stored. In this way, when the user stops the car again, the footrest 110 can trigger the striking balls 252 and protrusions 241 to strike again and emit a reminder sound. This design not only increases the convenience of use, but also avoids unnecessary noise interference.

[0035] 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.
