Abstract
Description
Technical Field
[0001] This utility model belongs to the field of helmet technology, specifically a helmet with an anti-theft rope. Background Technology
[0002] With the rapid development of the sharing economy, shared electric bikes have become an important means of transportation for short-distance urban travel due to their convenience and environmental friendliness, providing great convenience for users' daily travel. In order to ensure the personal safety of users during the ride and to comply with relevant traffic safety regulations, shared electric bikes on the market are generally equipped with special helmets, which are mandatory or guided for users to wear while riding.
[0003] However, in actual operation, the dedicated helmets provided with shared electric bikes face serious problems of loss or theft. Since the helmets are accessories independent of the vehicle body, they lack effective anti-theft measures. Some users may occupy or take the helmets away without permission, or the helmets may be maliciously stolen. This not only prevents subsequent users from using the helmets normally, affecting the quality of shared electric bike operation services, but also requires operating companies to frequently purchase new helmets to replenish them, which greatly increases the company's operating costs and management burden.
[0004] To reduce the risk of helmet loss and regulate user behavior, some shared electric bikes have incorporated helmet detection mechanisms into their designs. This is a common anti-theft improvement solution in existing technology. The core design idea of this solution is to embed a sensing device (such as an RFID sensing module or a Bluetooth sensing module) inside the helmet, and at the same time set up a corresponding signal receiving module on the vehicle body, so that the helmet and the vehicle body can establish a wireless connection.
[0005] However, existing technologies require the additional integration of sensors and corresponding communication modules inside the helmet, as well as the addition of signal receiving modules and circuit modifications to the vehicle body. This makes the structural design of the helmet and vehicle more complex, significantly increases the manufacturing cost of the product, and is not conducive to large-scale promotion and application. Because electronic components such as sensors and communication modules are exposed to the outdoor environment for a long time, they are susceptible to failure due to factors such as rain, dust, and impact. In addition, electronic components themselves have a certain lifespan limit, which undoubtedly increases the difficulty and cost of later maintenance. Operating companies need to invest a lot of manpower and resources in equipment repair and component replacement, further increasing the operational burden. Furthermore, this solution relies on the coordinated operation of electronic sensing and system control. If system failures or signal interference occur, the detection mechanism may fail, resulting in misjudgments that the helmet has not been returned or that the vehicle cannot be locked and returned properly, affecting the user experience and the company's operational efficiency. Utility Model Content
[0006] To overcome the above-mentioned defects, this utility model provides a helmet with an anti-theft rope, which solves the technical problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a helmet with an anti-theft rope, comprising a helmet body, an elastic rope, and a frame. A strap assembly is fixedly connected to the bottom of the helmet body, and a connecting buckle is provided on the strap assembly. A connecting rope is fixedly connected to one side of the helmet body, and the outer side of the connecting rope is snapped together with the connecting buckle. An elastic rope is fixedly provided at the other end of the connecting rope, and the other end of the elastic rope is fixedly connected to the frame.
[0008] As a further embodiment of this utility model: the strap assembly includes a first strap and a second strap, the end of the first strap is fixedly connected to the inner wall of the helmet body, the first strap is located on both sides of the helmet body, and the second strap is fixed between the first straps, and a buckle is provided between the second straps.
[0009] As a further embodiment of this utility model: the elastic rope has a spring-type structure, and the elastic rope and the connecting rope are integrally formed.
[0010] As a further embodiment of this utility model: the connecting buckle is disposed on the outside of the second strap, and a slot for cooperating with the connecting rope is provided on one side of the connecting buckle, the inner diameter of the slot being larger than the opening.
[0011] As a further embodiment of this utility model: one end of the connecting rope is provided with a bent part, a metal connecting block is sleeved on the outside of the bent part, a buckle is provided on one side of the inner wall of the helmet body, and the metal connecting block is fixedly connected to one side of the helmet body through the buckle.
[0012] As a further embodiment of this utility model: a metal shelf is provided on one side of the vehicle frame, and two sets of connecting pipes are provided above the metal shelf, with springs sleeved on the outer walls of the ends of the two sets of connecting pipes, and a metal U-shaped tube sleeved on the other end of the springs.
[0013] As a further embodiment of this utility model: a connecting plate is provided on one side of the metal shelf, and the connecting plate is fixedly connected to the vehicle frame by bolts.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The helmet's stability is ensured by using a strap assembly with a buckle and a connecting rope, preventing it from falling off during riding. It also allows for quick disassembly or reassembly for easy storage. The connection between the connecting rope and the frame via an elastic cord allows for integrated helmet and frame transport, eliminating the need for a separate storage bag or handheld helmet. This avoids issues like lost helmets or inconvenient carrying. The elastic cord also provides some flexibility, preventing excessive strain on the helmet due to bike movement during riding and adapting to different frame positions. Adjustments, storage, and retrieval are all quick and easy, enhancing the user experience. Through the cooperation of the first and second straps within the strap assembly, the first strap is fixed to both sides of the helmet body, and the second strap connects between the two first straps. With the locking buckle between the second straps, the helmet can be worn accurately and securely, adapting to the needs of people with different head circumferences and improving the reliability of wearing. The connecting buckle is set on the outside of the second strap, so that the connection point between the connecting rope and the strap assembly is located at the center of the strap assembly. With this structure, the end of the connecting rope connects to the connecting buckle located at the center of the strap assembly, below the user's chin. When wearing the helmet, the tension point of the spring-loaded elastic rope will be below the geometric center of the helmet, forming a stable and balanced force point. This can effectively prevent the helmet from tilting or twisting under the pull of the elastic rope, greatly improving the stability and comfort of wearing, and avoiding fatigue caused by unilateral pressure on the neck during long-term wear.

[0017] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0018] like Figures 1-7 As shown, this utility model provides a technical solution: A helmet with an anti-theft rope includes a helmet body 1, an elastic rope 8, and a frame 10. A strap assembly 2 is fixedly connected to the bottom of the helmet body 1. A connecting buckle 12 is provided on the strap assembly 2. A connecting rope 7 is fixedly connected to one side of the helmet body 1. The outer side of the connecting rope 7 is fastened to the connecting buckle 12. An elastic rope 8 is fixedly provided at the other end of the connecting rope 7. The other end of the elastic rope 8 is fixedly connected to the frame 10. Specifically, when in use, the strap assembly 2, which is fixedly connected to the bottom of the helmet body 1, is wrapped around the underside of the head and secured. If the helmet is not needed, the strap assembly 2 can be untied and the connecting rope 7 can be untied from the connecting buckle 12 on the strap assembly 2. Since the other end of the connecting rope 7 is fixed with an elastic rope 8, and the other end of the elastic rope 8 is fixedly connected to the frame 10, the helmet body 1 can be naturally hung next to the frame 10 without additional storage or holding. When using it again, simply remove the helmet body 1 from the side of the frame 10. If the buckle between the connecting rope 7 and the connecting buckle 12 was previously unfastened, you need to re-fasten the outer side of the connecting rope 7 to the connecting buckle 12, and then repeat the wearing and adjustment steps. The strap assembly 2, together with the connecting buckle 12 and the connecting rope 7, ensures the stability of the helmet body 1 when worn, preventing the helmet from falling off during riding. It also facilitates quick disassembly or reassembly when hanging and storing, making it easy to operate. The connecting rope 7, together with the elastic rope 8, is fixedly connected to the frame 10, realizing the integrated carrying of the helmet and the frame 10. There is no need to prepare an extra storage bag or hold the helmet by hand, avoiding the problems of helmet loss or inconvenience in carrying. At the same time, the elastic rope 8 has a certain degree of elasticity, so it will not cause excessive pulling on the helmet body 1 due to the shaking of the vehicle during riding. Whether it is wearing adjustment, hanging and storing, or retrieving, it can be done quickly, improving the user experience, and is especially suitable for daily use by cycling enthusiasts. The strap assembly 2 includes a first strap 3 and a second strap 4. The end of the first strap 3 is fixedly connected to the inner wall of the helmet body 1. The first strap 3 is located on both sides of the helmet body 1, and the second strap 4 is fixed between the first strap 3. A buckle 5 is provided between the second straps 4. The elastic rope 8 has a spring structure. The elastic rope 8 and the connecting rope 7 are integrally formed. The connecting buckle 12 is located on the outside of the second strap 4. A slot 13 for cooperating with the connecting rope 7 is opened on one side of the connecting buckle 12. The inner diameter of the slot 13 is larger than the opening. Specifically, the strap assembly 2 includes a first strap 3 and a second strap 4. First, the ends of the first straps 3 on both sides are fixed to the inner wall of the helmet body 1. Then, the second strap 4, which is fixed between the first straps 3 on both sides, is wrapped around the lower part of the head and locked by the buckle 5 set between the second straps 4 to complete the helmet wearing and fixing operation. Next, the connecting rope 7 is connected to the strap assembly 2. Since the elastic rope 8 is a spring structure and is integrally formed with the connecting rope 7, the end of the connecting rope 7 is aligned with the connecting buckle 12 set on the outside of the second strap 4. The connecting rope 7 is inserted into the opening of the slot 13 on one side of the connecting buckle 12 to achieve a stable connection between the connecting rope 7 and the connecting buckle 12. Through the cooperation of the first strap 3 and the second strap 4 in the strap assembly 2, the first strap 3 is fixed to both sides of the helmet body 1, and the second strap 4 is connected between the first straps 3 on both sides. With the buckle 5 between the second straps 4, the helmet can be worn accurately and stably, adapting to the needs of people with different head circumferences and improving the reliability of wearing. The connecting buckle 12 is set on the outside of the second strap 4, so that the connection point between the connecting rope 7 and the strap assembly 2 is located at the center of the strap assembly 2. With this structure, the end of the connecting rope 7 is connected to the connecting buckle 12 located at the center of the strap assembly 2 and below the user's chin. When wearing the helmet, the tension point of the spring elastic rope 8 will be below the geometric center of the helmet (i.e., at the chin), forming a stable and balanced force point. Compared with the existing technology where the elastic rope 8 is simply connected to one side of the helmet, which easily causes the helmet to be tilted and uncomfortable due to lateral tension, this can effectively prevent the helmet from tilting or twisting under the pull of the elastic rope 8, greatly improving the stability and comfort of wearing, and avoiding fatigue caused by unilateral pressure on the neck during long-term wearing. One end of the connecting rope 7 is provided with a bend, and a metal connecting block 6 is sleeved on the outside of the bend. A buckle 14 is provided on one side of the inner wall of the helmet body 1. The metal connecting block 6 is fixedly connected to one side of the helmet body 1 through the buckle 14. A metal shelf 11 is provided on one side of the frame 10. Two sets of connecting tubes are provided on the top of the metal shelf 11, and springs 16 are sleeved on the outer wall of the ends of the two sets of connecting tubes. A metal U-shaped tube 15 is sleeved on the other end of the springs 16. A connecting plate 9 is provided on one side of the metal shelf 11. The connecting plate 9 is fixedly connected to the frame 10 by bolts. Specifically, using the buckle 14 on one side of the inner wall of the helmet body 1, the metal connecting block 6 is connected to the buckle 14, thereby achieving a stable fixation of the connecting rope 7 to one side of the helmet body 1. Then, the installation of the metal shelf 11 on the side of the frame 10 is completed. The metal shelf 11 on one side of the frame 10 is fixedly connected to the frame 10 with bolts through the connecting plate 9 on its side. After the overall installation is completed, when it is necessary to place the helmet, first move the metal U-shaped tube 15 connected to the spring 16 sleeved on the outer wall of the two sets of connecting tubes above the metal shelf 11 to open the metal U-shaped tube 15. Then, place the helmet on the metal shelf 11. Then, release the metal U-shaped tube 15. Under the action of the restoring force of the spring 16, it automatically presses the top of the helmet to achieve the fixation of the helmet. To retrieve the helmet, simply flip the metal U-shaped tube 15 again to open it, and the helmet can be taken out. Since the connecting rope 7 is fixed to the helmet body 1, it can prevent the helmet from being lost when it is retrieved or placed. The connecting rope 7 is fixed to the inner wall of the helmet body 1 by a metal connecting block 6 fitted at the end bend. This structure ensures the firmness of the connection between the connecting rope 7 and the helmet body 1, and facilitates disassembly and maintenance. The metal connecting block 6 can enhance the structural strength of the bend and reduce the risk of breakage of the connecting rope 7 due to long-term stress. The working principle of this utility model is as follows: First, the helmet body 1 is secured to the head by the strap assembly 2 at the bottom. The ends of the first straps 3 on both sides of the assembly are fixed to the inner wall of the helmet body 1. The second straps 4, which are connected between the first straps 3 on both sides, are wrapped around the underside of the head and locked by the buckles 5 between the second straps 4, thus completing the secure wearing of the helmet and preventing the helmet from falling off during riding. Secondly, one end of the connecting rope 7 is fixed to the buckle 14 on one side of the inner wall of the helmet body 1 through the metal connecting block 6 sleeved on the end bend, so as to achieve a stable connection between the connecting rope 7 and the helmet body 1. The connecting rope 7 and the elastic rope 8 with spring structure are integrally formed. The other end of the elastic rope 8 is connected to the metal shelf 11 on the side of the frame 10. The connecting rope 7 can be connected to the connecting buckle 12 on the outside of the second strap 4. When wearing, the connecting rope 7 and the connecting buckle 12 are fixed, so that the tension point of the elastic rope 8 is located below the geometric center of the helmet (at the chin), forming a balanced force point. When not wearing, the buckle 5 and the buckle between the connecting rope 7 and the connecting buckle 12 are released, and the helmet can be fixed by the metal shelf 11 to achieve integrated carrying. It is worth mentioning that the metal rack 11 on the side of the frame 10 is fixed to the bolts by the side connecting plate 9. Two sets of connecting tubes with springs 16 are set on the top of the rack. The other end of the spring 16 is fitted with a metal U-shaped tube 15, which constitutes a spring pressure limiting mechanism. When the helmet is placed in the metal rack 11, the metal U-shaped tube 15 automatically presses the top of the helmet under the restoring force of the spring 16, realizing the active fixation of the helmet and effectively preventing the helmet from shifting or falling off when the frame 10 shakes or bumps. Finally, the metal connecting block 6 not only fixes the connecting rope 7 to the helmet body 1, but also enhances the structural strength of the bent part of the connecting rope 7, reducing the risk of breakage caused by long-term stress. The slot 13 on one side of the connecting buckle 12 adopts a design with an inner diameter larger than the opening, which not only facilitates the quick snapping of the connecting rope 7, but also ensures the stability of the connection. The spring-type elastic rope 8 has good elasticity and can adapt to the suspension requirements of different frame positions 10, avoiding excessive pulling on the helmet due to the shaking of the vehicle body, preventing the helmet from tilting or twisting under the traction of the elastic rope 8, improving wearing stability and comfort, and avoiding fatigue from unilateral pressure on the neck.
[0019] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
