Technical Field

[0001] This application relates to the field of vehicle technology, and more specifically, to a motorcycle. Background Technology

[0002] Motorcycle fuel tanks are equipped with fuel tank locks to open or close the fuel filler neck. In related technologies, the lock body and cover of the fuel tank lock are usually integrated, requiring the lock body and cover to be designed and replaced together. This necessitates adjustments to the appearance and structure of the fuel tank lock, resulting in high design and replacement costs. Utility Model Content

[0003] In view of this, this application provides a motorcycle with lower design and replacement costs when adjusting the appearance structure of its fuel tank lock.

[0004] One embodiment of this application provides a motorcycle. The motorcycle includes a fuel tank and a fuel tank lock. The fuel tank has a fuel filler neck. The fuel tank lock is mounted on the fuel filler neck of the fuel tank to open or close the fuel filler neck. The fuel tank lock includes a mounting bracket, a first fastener, a lock body, a cover plate, and a second fastener. The mounting bracket is connected to the fuel tank. The mounting bracket includes a mounting portion. The first fastener passes through the mounting portion from the side of the mounting portion away from the fuel tank and is connected to the fuel tank. The lock body is rotatably connected to the mounting bracket and can rotate relative to the mounting bracket to a locked position or an open position. When the lock body is in the locked position, the lock body can be connected to the fuel filler neck to close the fuel filler neck. When the lock body is in the open position, the lock body is separated from the fuel filler neck to open the fuel filler neck. The cover plate is mounted on the lock body and covers the side of the lock body away from the fuel tank. The cover plate includes a mounting portion. The second fastener passes through the lock body and is connected to the mounting portion. When the lock body is in the locked position, the cover plate covers the side of the first fastener away from the fuel tank, and the second fastener passes through the lock body and is connected to the side of the mounting portion facing the fuel tank.

[0005] In some embodiments of this application, the mounting bracket further includes a ring seat. The ring seat has an annular structure and an assembly space is formed within the annular structure. The mounting part is connected to / disposed on the ring seat and is located within the assembly space. When the lock body is in the locked position, both the lock body and the cover plate are at least partially located within the assembly space. When the lock body is in the open position, the mounting part is exposed within the assembly space.

[0006] In some embodiments of this application, there are multiple assembly parts, each assembly part is connected to a first fastener, and the multiple first fasteners are arranged at intervals around the center line of the ring seat. When viewed along the center line of the ring seat, the angle between the center of two adjacent first fasteners and the line connecting the center line of the ring seat ranges from 30° to 110°.

[0007] In some embodiments of this application, the cover plate further includes a plate body. The mounting portion is disposed on one side of the plate body. When the lock body is in the locked position, the annular structure ring of the ring seat is located on the outer periphery of the plate body, and the outer periphery of the plate body facing the oil tank is closer to the oil tank than the side of the ring seat facing away from the oil tank.

[0008] In some embodiments of this application, the mounting bracket further includes a hinge seat. The hinge seat is connected to the ring seat, and the hinge seat is located on the side of the ring seat facing the oil tank. The lock body is rotatably connected to the hinge seat.

[0009] In some embodiments of this application, the first fastener is provided in multiple forms, and at least some of the first fasteners pass through the hinge seat and are connected to the oil tank.

[0010] In some embodiments of this application, multiple mounting portions are provided, each connected to a second fastener. These second fasteners are spaced apart around the centerline of the cover plate. When viewed along the centerline of the cover plate, the angle between the line connecting the centers of two adjacent second fasteners and the centerline of the cover plate ranges from 30° to 110°. In some embodiments of this application, when viewed along the centerline of the cover plate, the distance between the centerline of the cover plate and the centerline of the second fastener is defined as a first distance, and the distance between the centerline of the cover plate and the outer edge of the cover plate is defined as a second distance. The ratio of the first distance to the second distance ranges from 0.05 to 0.5.

[0011] In some embodiments of this application, the lock body has a lock hole on the side opposite to the fuel tank. The cover plate has a recess to expose the lock hole. The fuel tank lock also includes a protective cover assembly. The protective cover assembly includes a protective cover body. The protective cover body is rotatably connected to the cover plate and is rotatable relative to the cover plate to a first position or a second position. When the protective cover body is in the first position, the protective cover body covers the lock hole. When the protective cover body is in the second position, the protective cover body separates from the lock hole to expose the lock hole.

[0012] In some embodiments of this application, the protective cover assembly further includes an elastic element. The elastic element is disposed between the protective cover body and the lock body. The protective cover body has a first mating surface and a second mating surface. When the protective cover body is in a first position, the elastic element abuts against the first mating surface to maintain the protective cover body in the first position. When the protective cover body is in a second position, the elastic element abuts against the second mating surface to maintain the protective cover body in the second position.

[0013] In this application, the mounting bracket, cover plate, and lock body are set separately. When adjusting the appearance structure of the fuel tank lock, it can be achieved by replacing the mounting bracket and cover plate without replacing the lock body, which reduces the replacement cost. Moreover, when designing the shape of the fuel tank lock, only the shape design of the mounting bracket and cover plate needs to be considered, thereby reducing the design difficulty and thus reducing the design cost.

Detailed Implementation

[0016] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0018] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be interpreted as indicating or implying relative importance.

[0019] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0020] See Figure 1 One embodiment of this application provides a motorcycle 100. The motorcycle 100 includes a fuel tank 10 and a fuel tank lock 20. The fuel tank 10 has a fuel filler neck (not shown). The fuel tank lock 20 is fitted onto the fuel filler neck of the fuel tank 10 to open or close the fuel filler neck.

[0021] See Figures 1 to 4 In some embodiments, the fuel tank lock 20 includes a mounting bracket 21, a first fastener 22, a lock body 23, a cover plate 24, and a second fastener 25. The mounting bracket 21 is connected to the fuel tank 10. The mounting bracket 21 includes a mounting portion 211. The first fastener 22 is configured to pass through the mounting portion 211 from the side of the mounting portion 211 opposite to the fuel tank 10 and connect to the fuel tank 10. The lock body 23 is rotatably connected to the mounting bracket 21 and can rotate relative to the mounting bracket 21 to a locked position or an open position. When the lock body 23 is in the locked position, it can connect to the fuel inlet to close the fuel inlet. When the lock body 23 is in the open position, it separates from the fuel inlet to open the fuel inlet. The cover plate 24 is connected to the lock body 23 and rotates with the lock body 23 relative to the mounting bracket 21. The cover plate 24 includes a mounting portion 241. The second fastener 25 is configured to pass through the lock body 23 and connect to the mounting portion 241. Specifically, the side of a structure facing away from the fuel tank 10 can be understood as the side of the structure that faces the user when looking at the fuel tank 10; conversely, the side of a structure facing the fuel tank 10 can be understood as the side of the structure that faces away from the user when looking at the fuel tank 10. Figure 2 The diagram shows the structure of the lock body 23 in the open position; Figure 3 The diagram shows the structure of lock body 23 in the locked position. Figure 3 The first fastener 22 has been omitted; Figure 4 Compared Figure 2 The first fastener 22 has been omitted.

[0022] The mounting bracket 21, cover plate 24, and lock body 23 are separate components. Adjustments to the appearance of the fuel tank lock 20 can be made simply by replacing the mounting bracket 21 and cover plate 24, without needing to replace the lock body 23. This reduces replacement costs. Furthermore, since the lock body 23 is used to close or open the fuel tank 10's filling port, the sealing performance between the lock body 23 and the fuel tank 10 can be maintained well, thus reducing design complexity and costs.

[0023] When the lock body 23 is in the locked position, the cover plate 24 covers the mounting part 211 and the first fastener 22 on the side away from the oil tank 10, and the second fastener 25 passes through the lock body 23 and is connected to the mounting part 241 on the side facing the oil tank 10.

[0024] When the lock body 23 is in the open position, the assembly part 211, the first fastener 22, the mounting part 241, and the second fastener 25 are all exposed, allowing the first fastener 22 to be assembled or disassembled with the assembly part 211 and the second fastener 25 to be assembled or disassembled with the mounting part 241, thereby enabling the assembly or disassembly of the fuel tank lock 20. When the lock body 23 is in the locked position, the lock body 23 can be locked with the fuel tank 10 to close the oil inlet. The lock body 23 and the cover plate 24 are fixed relative to the mounting bracket 21 and cannot rotate. Thus, the assembly part 211, the first fastener 22, the mounting part 241, and the second fastener 25 are all within the relatively enclosed space formed by the cover plate 24, the mounting bracket 21, and the fuel tank 10, making it impossible to remove the first fastener 22 and the second fastener 25. This is beneficial for theft prevention and protects the security of the fuel tank lock 20 locked in the fuel tank 10.

[0025] See Figure 2 and Figure 4 It is understood that in some embodiments, the first fastener 22 is a bolt, the assembly part 211 has a through hole and the oil tank 10 has a screw hole. The first fastener 22 passes through the through hole of the assembly part 211 and is threaded to the screw hole of the oil tank 10, thereby enabling the first fastener 22 to lock the assembly bracket 21 to the oil tank 10; the second fastener 25 is a bolt, the lock body 23 has a through hole and the mounting part 241 has a screw hole. The second fastener 25 passes through the through hole of the lock body 23 and is threaded to the screw hole of the mounting part 241, thereby enabling the second fastener 25 to lock the lock body 23 to the cover plate 24; the threaded connection fixing method of the first fastener 22 and the second fastener 25 facilitates assembly and disassembly, and facilitates the reuse of the assembly bracket 21 and the cover plate 24.

[0026] See Figures 2 to 5 In some embodiments, the assembly bracket 21 further includes a ring seat 212. The ring seat 212 has an annular structure and an assembly space 2121 is formed within the annular structure. The assembly part 211 is connected to / disposed on the ring seat 212 and is located within the assembly space 2121.

[0027] When the lock body 23 is in the locked position, both the lock body 23 and the cover plate 24 are at least partially located in the assembly space 2121. The assembly part 211 is located within the assembly space 2121, which allows the cover plate 24 to partially cover the assembly part 211 within the annular structure of the ring seat 212, thereby improving the anti-theft effect.

[0028] When the lock body 23 is in the open position, the assembly part 211 is exposed in the assembly space 2121. After the lock body 23 opens the oil filling port, the cover plate 24 also leaves the assembly space 2121 to avoid obstructing the assembly part 211, thus facilitating the assembly or disassembly of the first fastener 22 and the assembly part 211.

[0029] See Figure 4 and Figure 5It is understood that in some embodiments, the assembly part 211 and the ring seat 212 are integrally formed structures, which improves the structural stability of the assembly bracket 21 and reduces assembly and disassembly steps.

[0030] See Figure 1 and Figure 2 In some embodiments, multiple assembly parts 211 are provided. Each assembly part 211 is provided with a first fastener 22. The multiple assembly parts 211 are arranged at intervals along the annular structure of the ring seat 212, and the multiple first fasteners 22 are arranged at intervals around the center line of the ring seat 212. The inner circumference of the annular structure of the ring seat 212 is approximately circular, and the multiple assembly parts 211 are distributed in a ring relative to the same center. The radii of different assembly parts 211 relative to the center can be the same or different. The multiple assembly parts 211, in conjunction with the multiple first fasteners 22, can improve the stability of the connection and fixation between the assembly bracket 21 and the oil tank 10.

[0031] See Figure 6 In some embodiments, when viewed along the centerline of the ring seat 212, the angle α between the center of two adjacent first fasteners 22 and the line connecting the centerline of the ring seat 212 ranges from 30° to 110°. For example, α can be 110°, 90°, 75°, 60°, or 45°. It should be noted that the first fastener 22 is a bolt, and its center is on the centerline of the bolt. In the above structure, the portion of the ring seat 212 located between two adjacent assembly parts 211 is difficult to pry up, improving the anti-theft effect.

[0032] See Figure 2 , Figure 3 and Figure 5 In some embodiments, the cover plate 24 further includes a plate body 242. A mounting portion 241 is provided on one side of the plate body 242. When the lock body 23 is in the locked position, the plate body 242 can cover the mounting portion 211 and the first locking member, and fasten the mounting portion 241 and the second locking member to the underside to improve the anti-theft effect.

[0033] See Figure 4 and Figure 5 It is understood that in some embodiments, the mounting part 241 and the plate 242 are integrally formed structures, which improves the structural stability of the cover plate 24 and reduces assembly and disassembly steps.

[0034] See Figure 1 , Figure 2 and Figure 4In some embodiments, when the lock body 23 is in the locked position, the annular structure of the ring seat 212 is arranged around the periphery of the plate body 242, and the side of the periphery of the plate body 242 facing the oil tank 10 is closer to the oil tank 10 than the side of the ring seat 212 facing away from the oil tank 10. When the lock body 23 is in the locked position, the plate body 242 can be at least partially embedded in the annular structure of the ring seat 212, thereby reducing the possibility of prying the plate body 242 open from between the plate body 242 and the ring seat 212, and improving the anti-theft effect.

[0035] See Figures 4 to 6 In some embodiments, multiple mounting portions 241 are provided. These multiple mounting portions 241 are located on the same side of the plate 242. Each mounting portion 241 is provided with a second fastener 25. The multiple mounting portions 241 are arranged in a ring around the same center, and the radii of different mounting portions 241 relative to this center can be the same or different; and the center of the ring distribution of the multiple mounting portions 241 can coincide with the center of the ring distribution of the multiple assembly portions 211. The multiple mounting portions 241 are arranged at intervals around the lock body 23. The multiple mounting portions 241, in conjunction with the multiple second fasteners 25, can improve the stability of the connection and fixation between the cover plate 24 and the lock body 23.

[0036] See Figure 6 In some embodiments, when viewed along the centerline of the cover plate 24, the angle β between the center of two adjacent second fasteners 25 and the line connecting the centerline of the cover plate 24 ranges from 30° to 110°. For example, β can be 110°, 90°, 75°, 60°, or 45°. The second fastener 25 is a bolt, and its center is located on the centerline of the bolt. In this structure, the portion of the cover plate 24 between two adjacent mounting portions 241 is difficult to pry up, improving the anti-theft effect.

[0037] See Figure 5 and Figure 6 In some embodiments, multiple mounting portions 241 are provided. These multiple mounting portions 241 are located on the same side of the plate 242. Each mounting portion 241 has at least one second fastener 25. The multiple mounting portions 241 are spaced apart around the lock body 23. Viewed along the centerline of the cover plate 24, the distance between the centerline of the cover plate 24 and the centerline of the second fastener 25 is defined as a first distance L1, and the distance between the centerline of the cover plate 24 and the outer edge of the cover plate 24 is defined as a second distance L2. The ratio of the first distance L1 to the second distance L2 ranges from 0.05 to 0.5. For example, L1 can be half, two-thirds, or three-quarters of L2. In the above structure, each mounting portion 241 is closer to the outer edge of the plate 242 to increase the difficulty of prying up the edge of the plate 242, thereby improving the anti-theft effect.

[0038] in, Figure 6The cover plate 24 and the protective cover body 261 (described later) are omitted; the structure of the lock body 23 through which the second fastener 25 passes corresponds to the position of the mounting part 241, therefore... Figure 6 The position of the through hole through the second fastener 25 in the lock body 23 corresponds to the position of the mounting part 241 and is used to indicate L1; when the lock body 23 is in the locked position, the outer edge of the plate 242 basically abuts against the inner circumference of the annular structure of the ring seat 212, therefore Figure 6 L2 is represented by the radius of the inner circumference of the annular structure of the ring seat 212.

[0039] See Figure 4 and Figure 5 In some embodiments, the mounting bracket 21 further includes a hinge seat 213. The hinge seat 213 is connected to the ring seat 212, and the hinge seat 213 is located on the side of the ring seat 212 facing the oil tank 10. The lock body 23 is rotatably connected to the hinge seat 213. In the above structure, the ring seat 212 can cover the side of the structure opposite to the oil tank 10 at the rotatable connection between the lock body 23 and the mounting bracket 21, thereby enclosing the rotatable connection structure between the ring seat 212 and the oil tank 10. When the lock body 23 closes the oil inlet (i.e., when the lock body 23 is in the locked position), it can prevent the rotatable structure from being exposed, thereby improving the anti-theft effect.

[0040] See Figure 3 and Figure 5 Understandably, in some embodiments, the hinge seat 213 has two spaced-apart hinge arms 2131. Both hinge arms 2131 protrude toward the ring seat 212. The mounting bracket 21 also includes a first rotation shaft 214. A portion of the lock body 23 is located between the two hinge arms 2131, and the first rotation shaft 214 passes through the two hinge arms 2131 and the portion of the lock body 23 located between the two hinge arms 2131, so that the lock body 23 can rotate relative to the hinge seat 213. A portion of the ring seat 212 can stop on the opposite sides of the two hinge arms 2131 to prevent the first rotation shaft 214 from disengaging from the lock body 23 and the hinge arms 2131.

[0041] See Figures 1 to 3 In some embodiments, the first fastener 22 passes through the hinge seat 213 and is connected to the oil tank 10. The first fastener 22 connects multiple structures to simplify the structure of the assembly bracket 21, save the space occupied by the assembly bracket 21, and help reduce production costs.

[0042] See Figure 1 , Figure 3 and Figure 5In some embodiments, the lock body 23 has a lock hole 231 on the side opposite to the fuel tank 10. The cover plate 242 has a recess 2421 to expose the lock hole 231. The fuel tank lock 20 also includes a protective cover assembly 26. The protective cover assembly 26 includes a protective cover body 261. The protective cover body 261 is rotatably connected to the cover plate 24 and is rotatable relative to the cover plate 24 to a first position or a second position. When the protective cover body 261 is in the first position, the protective cover body 261 covers the lock hole 231 to conceal the lock hole 231. When the protective cover body 261 is in the second position, the protective cover body 261 separates from the lock hole 231 to expose the lock hole 231. By setting the protective cover assembly 26, when it is not necessary to unlock the lock body 23, the protective cover 261 can be rotated to the first position to protect the key hole 231, which helps to maintain the working performance of the lock body 23; when it is necessary to unlock the lock body 23, the protective cover can be rotated to the second position to expose the key hole 231, making it convenient to unlock the lock body 23.

[0043] in, Figure 2 The diagram shows the structure of the protective cover 261 in the first position; the diagrams do not show the structure of the protective cover 261 in the second position.

[0044] See Figure 4 , Figure 5 and Figure 7 In some embodiments, the protective cover assembly 26 further includes an elastic element 262. The elastic element 262 is disposed between the protective cover body 261 and the lock body 23. The protective cover body 261 has a first mating surface 2611 and a second mating surface 2612. When the protective cover body 261 is in a first position, the elastic element 262 abuts against the first mating surface 2611 to maintain the protective cover body 261 in the first position. When the protective cover body 261 is in a second position, the elastic element 262 abuts against the second mating surface 2612 to maintain the protective cover body 261 in the second position. When the protective cover body 261 rotates, it can compress the elastic element 262 to elastically deform, thereby allowing the protective cover body 261 to switch the surface that abuts against the elastic element 262. For example, the elastic element 262 can be a spring sheet. In the above structure, the elastic member 262 applies an elastic force to the first mating surface 2611 or the second mating surface 2612, so that the protective cover 261 can be stably maintained in the first position to protect the lock body 23 or stably maintained in the second position to facilitate unlocking the lock body 23 when no external force is applied.

[0045] In some embodiments, the protective cover assembly 26 further includes a second rotating shaft 263. The second rotating shaft 263 is disposed between the cover plate 24 and the lock body 23, and the second drive shaft passes through the protective cover body 261, so that the protective cover body 261 can rotate relative to the cover plate 24. As the cover plate 24 is placed on the lock body 23, the cover plate 24 can cooperate with the lock body 23 to clamp the second rotating shaft 263 between the two and constrain the position of the second rotating shaft 263, which helps to simplify the structure of the cover plate 24 and the lock body 23, so as to reduce the overall size of the fuel tank lock 20.

[0046] Understandably, in some embodiments, the elastic element 262 is located between the second rotating shaft 263 and the lock body 23. The second rotating shaft 263 can cooperate with the lock body 23 to constrain the position of the elastic element 262 so as to protect the cover body 261 from rotation.

[0047] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
