Description

Technical Field

[0001] This patent belongs to the field of transportation technology, specifically referring to a scooter. Background Technology

[0002] In existing scooters, such as the scooter folding and locking mechanism disclosed in Chinese Patent 202021063897X, the locking buckle and its rotating structure used for fixing are exposed outside the scooter, which are easily damaged by collisions with the outside world, thus affecting the folding and locking of the scooter. Moreover, after the scooter is folded, the locking mechanism between the handlebar and the pedal is not stable enough, which can easily cause the two to fall off or loosen, affecting the storage of the scooter.

[0003] Furthermore, existing scooter wheels use a method where the tire valve is installed via an opening on the outer rim of the wheel hub that connects to one side of the hub. This opening is integrally formed on the wheel hub. This wheel hub design makes tire installation difficult, requiring the installer to manually insert a short valve into the opening. Moreover, the size of the opening is determined during wheel hub manufacturing, and when the valve is inserted into this opening, a gap inevitably exists between the opening and the valve, making it prone to leakage.

[0004] Furthermore, most existing scooters use motorized front wheels, which means that control cables for these motorized wheels are installed in the front forks on both sides of the scooter. Therefore, existing scooters also have covers on the front forks to cover these control cables. These covers are currently installed with screws, affecting the appearance and requiring a complex and inefficient installation process. Summary of the Invention

[0005] The purpose of this patent is to provide a scooter.

[0006] The purpose of this patent is achieved as follows:

[0007] A scooter includes a connecting rod and a footboard, and wheel hubs disposed at both ends of the footboard. The rod includes a rotatably folding bar. The scooter is characterized by further comprising:

[0008] A keyhole is provided on the folding rod and moves with the folding rod;

[0009] A locking groove is provided on the pedal; a locking hole is formed in the locking groove, and the locking groove is connected to a locking cavity located in the pedal through the locking hole; and

[0010] The lock cylinder has a drive assembly in the locking cavity that drives the lock cylinder to move through the locking hole; when the folding rod is rotated to the pedal, the keyhole is placed in the locking groove, and the lock cylinder passes through the locking hole and enters the keyhole.

[0011] Furthermore, the driving assembly includes a locking member rotatably disposed in the locking cavity, and a torsion spring is provided at its rotation point to drive the locking member to rotate to one side;

[0012] The locking component has a lock cylinder at one end and a drive head at the other end.

[0013] The pedal has a drive hole on one side of the locking groove, and the drive hole accommodates the drive head. When the keyhole is placed in the locking groove, the lock cylinder passes through the locking hole and enters the keyhole under the drive of the locking member. The lock cylinder is then disengaged from the keyhole by operating the drive head.

[0014] Furthermore, the size of the drive head is adapted to the drive hole, and the locking member is rotated by operating the drive head to move the edge of the drive hole.

[0015] Furthermore, the side of the wheel hub is provided with an air nozzle groove, and one end of the air nozzle groove is provided with an opening extending to the outer arc surface of the wheel hub, and a pressure block is detachably fixed in the opening.

[0016] When the pressure block is located inside the opening, an air nozzle is formed between the pressure block and the hub, through which the air nozzle passes.

[0017] Furthermore, the hub on one side of the opening is provided with an overlap groove, and the pressure block is provided with an overlap portion that overlaps in the overlap groove. When the pressure block is located inside the opening, the overlap portion is positioned in the overlap groove.

[0018] Furthermore, a cover is detachably connected to the side of the wheel hub. When the cover is fixed to the wheel hub, the cover closes the pressure block located in the opening.

[0019] Furthermore, the pressing block is made of a soft material.

[0020] Furthermore, a fork is provided between the rod and the wheel hub for connection. The fork includes a main frame, and a receiving groove is provided on one side of the main frame. A wire hole for connecting the wire in the wheel hub is provided in the receiving groove. A groove cover for closing the receiving groove is detachably fixed outside the receiving groove by a snap-fit ​​assembly.

[0021] Furthermore, the buckle assembly includes a plurality of strip holes disposed in the receiving groove, and a plurality of positioning buckles disposed on the groove cover and corresponding to the strip holes, wherein the ends of the positioning buckles have downwardly offset positioning ends.

[0022] Furthermore, the fork also includes an inner support, which is connected to the rod and the wheel hub respectively; the main frame covers and is fixed to the inner support and connected to it; a cable routing hole is provided in the receiving groove, and a cable clamping plate is provided in the cable routing hole, which is used to restrict the wire between the inner support and the cable clamping plate.

[0023] The outstanding and beneficial technical effects of this patent compared to existing technologies are:

[0024] This patent achieves locking of the folding rod by setting a drive component in the locking cavity between the upper and lower plates, and driving the lock cylinder on it to extend into or leave the locking groove through the drive component; since most of the drive component is hidden between the upper and lower plates, the drive component is not easily damaged, thereby increasing the stability and lifespan of the scooter folding.

[0025] The wheel hub in this patent features a detachable pressure block. Therefore, during valve installation, it's unnecessary to align the valve with the valve opening on the wheel hub. The user can directly place the valve into the open valve slot, and then install the pressure block for positioning. The detachable pressure block significantly reduces the difficulty of valve assembly. Furthermore, because the pressure block is made of a soft material, it compresses the valve within the valve slot during installation, eliminating gaps between the valve opening and achieving waterproofing.

[0026] The slot cover in this patent is assembled using a snap-fit ​​assembly, eliminating the need for screws and thus increasing product manufacturing efficiency. Attached Figure Description

[0049] The present patent will be further described below with reference to specific embodiments:

[0050] A scooter includes a handlebar 1, a footboard 2, and wheel hubs 3 disposed at both ends of the footboard 2, wherein a fork 4 is provided for connection between the handlebar 1 and the wheel hubs 3 and between the footboard 2 and the wheel hubs 3.

[0051] like Figure 1 , 2 As shown, the handlebar 1 consists of two parts, an upper and a lower part. It includes a connecting rod 12, which connects to the pedal 2 and the wheel hub 3. A folding rod 11 is rotatably connected to the upper end of the connecting rod 12. The connecting rod 12 and the folding rod 11 are hinged together and fixed by a lever structure 13. The lever structure 13 can refer to the folding structure in existing bicycles or scooters, and will not be described in detail in this patent. The folding rod 11 is used to rotate onto the pedal 2 for folding. A handlebar 14 is connected to the upper end of the folding rod 11, which controls the orientation of the entire handlebar 1, thereby changing the direction of the vehicle.

[0052] Specifically, such as Figure 8 As shown, the upper end of the folding rod 11 is provided with a keyhole 111, which includes a hole integrally formed on the folding rod 11 and located between the two handlebars 14. The pedal 2 is provided with a locking groove 21, and a locking hole 211 is opened in the locking groove 21. The locking groove 21 is connected to a locking cavity 22 located in the pedal 2 through the locking hole 211. A driving assembly is provided in the locking cavity 22, and a lock cylinder 231 is driven by the driving assembly, so that the lock cylinder 231 is movably inserted into the locking hole 211. When the folding rod 11 is rotated onto the pedal 2, the keyhole 111 is placed in the locking groove 21, and the lock cylinder 231 passes through the locking hole 211 and enters the keyhole 111, thereby locking the handlebars 14 and the pedal 2.

[0053] like Figure 3-5 As shown, the pedal 2 in this patent includes an upper plate 25 and a lower plate 26. A battery compartment 27 is formed at the front end of the upper plate 25, and the upper side of the battery compartment 27 is sealed by a decorative plate 28. The rear end of the upper plate 25 is located above the rear wheel hub 3 of the scooter, and a locking groove 21 is formed thereon. Specifically, the locking groove 21 is formed by bending or stretching the upper plate 25, and a locking hole 211 is opened on one side wall of the locking groove 21. The lower end of the rear end of the upper plate 25 is also provided with a lower plate 26, such as... Figure 4 , 5As shown, the tail end of the lower plate 26 is connected to the tail end of the upper plate 25. The lower plate 26 extends forward and is placed at the lower end of the tail of the upper plate 25, and the locking cavity 22 is formed between the lower plate 26 and the upper plate 25.

[0054] like Figure 5 As shown, the driving assembly in this patent includes a locking member 23 rotatably disposed in the locking cavity 22. The locking member 23 has a "V" shaped cross-section. A bracket is provided in the locking cavity 22, and the middle part of the locking member 23 is rotatably disposed on the bracket of the locking cavity 22. A torsion spring is provided at the rotation point of the locking member 23 to drive the locking member 23 to rotate to one side. One end of the locking member 23 is provided with the lock cylinder 231, and the other end is provided with a driving head 232, as shown... Figure 6 As shown, the upper plate 25 has a drive hole 24 on one side of the locking groove 21 at its tail, and the drive head 232 is accommodated in the drive hole 24.

[0055] Specifically, such as Figure 5 As shown, the lock cylinder 231 is specifically an arc-shaped hook. The upper end of the arc-shaped hook is used to accommodate the rotation of the locking member 23. A torsion spring drives the locking member 23 to rotate, causing the hook to pass through the locking hole 211 and enter the locking groove 21. Under normal conditions, the hook is located in the locking groove 21 under the drive of the locking member 23, combined with... Figure 2 , 3 As shown in Figure 5, when the end of the folding rod 11 rotates onto the pedal 2, the outer edge of the keyhole 111 abuts against the upper end of the hook. Since the hook has an arc-shaped upper surface, when the outer edge of the keyhole 111 contacts the hook, it presses against the upper surface of the hook. When the outer edge of the keyhole 111 abuts against the arc-shaped upper surface, it gives the entire locking member 23 a tendency to rotate inwards. This causes the locking member 23 to rotate inwards when the hook is pressed, causing the hook to partially exit the locking groove 21, allowing the folding rod 11 to continue rotating. Since the shape of the locking groove 21 is adapted to the end of the folding rod 11, when the folding rod 11 continues to rotate, the outer edge of its keyhole 111 abuts against the bottom of the locking groove 21, and its keyhole 111 is opposite to the locking hole 211. At this time, the hook is reset under the action of the torsion spring and enters the keyhole 111 for locking.

[0056] The drive head 232 is used to disengage the lock cylinder 231 from the keyhole 111 by operating the drive head 232. Figure 5 , 6As shown, the upper plate 25 has an inclined surface at its tail. The locking groove 21 and the driving hole 24 are arranged vertically at the tail of the upper plate 25. At this time, the upper plate 25 has a vertical abutment surface 242 on one side of the driving hole 24. The size of the driving head 232 is adapted to the driving hole 24. When the driving head 232 moves in the driving hole 24, one side of the driving head 232 is in contact with the abutment surface 242, and the movement of the driving head 232 is guided by the abutment surface 242. In addition, when the driving head 232 is pressed, the driving head 232 will also move along the edge of the driving hole 24, and is guided by the adapted driving hole 24 and the driving head 232.

[0057] The locking member 23 has a rotating pin 241 on one end where the driving head 232 is located, and the lower end of the driving head 232 is rotatably connected to the rotating pin 241. Specifically, as follows... Figure 7 As shown, the locking member 23 has a transition hole 243 on one end where the driving head 232 is located, facing the left and right sides of the locking member 23. The rotating pin 241 is inserted into the transition hole 243. The lower end of the driving head 232 has extension heads 2321 on both sides that connect to the rotating pin 241.

[0058] When it is necessary to reset the folded lever 11, simply press the drive head 232 to rotate the locking member 23 so that the lock cylinder 231 can exit the keyhole 111. At this time, the user can manually drive the folded lever 11 to reset it and reset it through the lever structure 13 on the folded lever 11.

[0059] In summary, this patent achieves the locking of the folding rod 11 by setting a drive assembly in the locking cavity 22 between the upper plate 25 and the lower plate 26, and by driving the lock cylinder 231 on it to extend into or leave the locking groove 21 through the drive assembly; since most of the drive assembly is hidden between the upper plate 25 and the lower plate 26, the drive assembly is not easily damaged, thereby increasing the stability and lifespan of the scooter folding.

[0060] Furthermore, the front end of the upper plate 25 is provided with a battery compartment 27, in which a battery 271 and wires 272 connected to the battery 271 are installed; the outer casing of the battery 271 is provided with several cable management racks 273 for placing the wires 272. Figure 16 , 17 As shown, the upper plate 25 has an opening, and the battery compartment 27 is connected below the opening; a decorative plate 28 is provided above the opening on the upper plate 25, and the battery compartment 27 is closed by closing the opening with the decorative plate 28. Figure 17As shown, the cable management rack 273 includes several support plates formed on one side of the battery 271 casing. The support plates are offset upwards, thereby forming gaps between adjacent support plates for placing wires 272. The battery 271 casing has labeling 274 on one side of the cable management rack 273, such as power supply, motor, brake, etc. The cable management rack 273 can be used to separate different wires 272 to classify and store the wires 272 in the battery compartment 27, making it easier for users to find faulty wires 272 in the battery compartment 27.

[0061] Furthermore, support plates with different offset degrees are provided for different types of wires 272. Taking power cords as an example, since power cords are thicker, the support plate used to support them has a larger offset angle and its size is correspondingly increased. Figure 17 As shown, the support plate used to support the power cord is tilted upwards at about 90 degrees and is arc-shaped, which can support thicker wires 272.

[0062] Furthermore, the side of the hub 3 is provided with an air nozzle groove 31, and one end of the air nozzle groove 31 is provided with an opening 32 extending to the outer arc surface of the hub 3. A pressure block 33 is detachably fixed in the opening 32. When the pressure block 33 is located in the opening 32, an air nozzle opening 34 for the air nozzle to pass through is formed between the pressure block 33 and the hub 3.

[0063] like Figure 11 , 14 As shown in Figure 15, the hub 3 is made of metal, and an axle 37 is inserted through the center of the hub 3. The hub 3 has a circular outer arc surface, and a tire is mounted on the outer arc surface. During the manufacturing process, a strip-shaped valve groove 31 is integrally formed on one side of the hub 3 using a mold. The valve groove 31 extends from the center of the hub 3 to the outer edge of the hub 3, and then to the outer arc surface, thereby forming an open opening 32 at one end of the valve groove 31.

[0064] Combination Figure 14 , 15 As shown, the pressure block 33 is made of a soft material, such as rubber or soft plastic. Its shape is configured to fit the opening 32, and by directly inserting the pressure block 33 into the opening 32, an air nozzle 34 is formed between the pressure block 33 and the hub 3 for the air nozzle to pass through. Specifically... Figure 15As shown, the opening 32 is provided with a first arc groove 321, and a second arc groove 322 is provided in the middle of the first arc groove 321. The upper end of the pressure block 33 is adapted to the plane from the side of the wheel hub 3, and the lower end of the pressure block 33 is provided with a first arc surface 332 adapted to the first arc groove 321. An upward third arc groove 333 is provided in the first arc surface 332. When the pressure block 33 is located in the opening 32, the air nozzle 34 is formed between the second arc groove 322 and the third arc groove 333.

[0065] When installing a vehicle tire, the wheel hub 3 in this patent first removes the pressure block 33, and then the tire is fitted onto the outer arc surface of the wheel hub 3. At this time, the user can operate the tire valve and place the valve in the open valve groove 31. Then, the pressure block 33 is driven to install in the opening 32 and fixed, so that the valve is positioned on the valve opening 34 formed in the second arc groove 322 and the third arc groove 333.

[0066] Because the wheel hub 3 in this patent has a detachable pressure block 33, the valve stem does not need to be aligned with the valve opening 34 on the wheel hub 3 during installation. The user can directly place the valve stem in the open valve slot 31. After the valve stem is placed, the pressure block 33 is installed for positioning. The detachable pressure block 33 significantly reduces the difficulty of valve stem assembly. Moreover, because the pressure block 33 is made of a soft material, when the pressure block 33 is fixed, the soft pressure block 33 will compress the valve stem located in the valve slot 31, thereby eliminating the gap between the valve opening 34 and the valve stem, achieving waterproofing.

[0067] Furthermore, a detachable cover 36 is provided on the side of the wheel hub 3. The cover 36 is annular and used for decoration. Several clearance grooves 35 are provided on the outer edge of the side of the wheel hub 3. These clearance grooves 35 reduce the material used in the wheel hub 3. The cover 36 is installed to close the clearance grooves 35, thus enhancing the aesthetics. Simultaneously, since the opening 32 is located at the outer end of the valve slot 31, it is situated between two adjacent clearance grooves 35. When the cover 36 is fixed to the wheel hub 3, it can simultaneously close the pressure block 33 located between two clearance grooves 35, thereby securing the pressure block 33.

[0068] Furthermore, the hub 3 on one side of the opening 32 is provided with an overlapping groove 351, and the pressure block 33 is provided with an overlapping part 331 that overlaps in the overlapping groove 351. When the pressure block 33 is located inside the opening 32, the overlapping part 331 is positioned within the overlapping groove 351. Figure 14 , 15As shown, the overlapping groove 351 is provided on both sides of the opening 32 and is connected to the clearance groove 35. The left and right ends of the pressure block 33 have integrally formed overlapping parts 331 that are adapted to the overlapping groove 351. The overlapping parts 331 are located in the overlapping groove 351 to position the pressure block 33 in the opening 32, and then the cover plate is used for vertical positioning to fix the pressure block 33.

[0069] Furthermore, the scooter in this patent uses motor wheels, such as... Figure 10 As shown, the axle 37 of the hub 3 is hollow, and a wire connecting the inside of the wheel is provided inside. The other end of the guide is connected to the battery compartment 27 of the pedal 2 through the fork 4.

[0070] like Figure 9 , 10 As shown, the fork 4 in this patent includes a main frame 41 with a "U" shaped cross section. The two sides of the main frame 41 are in contact with the sides of the wheel hub 3, and its ends are fixed to the sides of the wheel hub 3 on both sides of the wheel axle 37 by brackets.

[0071] like Figure 10 As shown, a square receiving groove 42 is formed on the side of the main frame 41. The receiving groove 42 is provided with a wire hole 421 for connecting the wire in the hub 3. The wire passes through the wire hole 421 and is located in the receiving groove 42, and extends upward. A groove cover 43 for closing the receiving groove 42 is detachably fixed to the outside of the receiving groove 42 by a snap-fit ​​assembly. The groove cover 43 closes the receiving groove 42 and positions the wire located in the receiving groove 42.

[0072] Specifically, such as Figure 10-12 As shown, the snap-fit ​​assembly includes a plurality of vertically oriented strip holes 422 disposed on the edge of the receiving groove 42, and a plurality of positioning buckles 431 disposed on the groove cover 43 and corresponding to the strip holes 422, as detailed below. Figure 12 As shown, the end of the positioning buckle 431 has a downwardly offset positioning end 432, so that the overall cross-section of the positioning buckle 431 is "L" shaped. When the slot cover 43 in this patent is installed, the positioning buckle 431 is first put into the strip hole 422, and then the slot cover 43 is driven to move downward so that the positioning end 432 is fastened to the lower end of the strip hole 422 for positioning, thereby realizing the installation of the slot cover 43.

[0073] At this time, the guide is confined within the receiving groove 42. Since the groove cover 43 in this patent is assembled by a snap-fit ​​assembly, no screws are required, thereby increasing product manufacturing efficiency.

[0074] Furthermore, the fork 4 also includes an inner support 44, which connects the rod 1 and the wheel hub 3 respectively; the main frame 41 covers and is fixed to the inner support 44 and connected to it. Figure 11 As shown, the inner support 44 is made of metal, and its cross-section is set in a "U" shape to fit the main support. The two ends of the inner support 44 are fixed to the two ends of the wheel hub 3 by brackets. The main frame 41 covers the inner support 44 and is fixed to the inner support 44 by screws. In addition, the main frame 41 is provided with mudguards 45 on the front and rear sides of the inner support 44. In order to facilitate the setting of the receiving groove 42 and the strip hole 422 structure, the manufacturer usually chooses to make the main frame 41 of plastic or other easy-to-shape materials. However, the main frame 41 of plastic material has limited strength and unstable structure, and cannot play the role of front fork connection. Therefore, the inner support 44 of metal material is set for support.

[0075] Furthermore, the receiving groove 42 is provided with a cable routing hole 423, and a cable clamping plate 424 is provided in the cable routing hole 423. The cable clamping plate 424 is used to restrict the wire between the inner bracket 44 and the cable clamping plate 424. Figure 10 , 13 As shown, the cable routing hole 423 is located in the middle of the receiving groove 42, and the inner support 44 is present in the cable routing hole 423; the clamping plates 424 are distributed on the left and right sides of the cable routing hole 423, and the clamping plates 424 are slightly offset upward. When the wire is located in the receiving groove 42, the lower end of the wire is supported on the inner support 44, and its upper end is positioned by the clamping plates 424; the clamping plates 424 are used to position the wire to prevent the wire from shaking in the receiving groove 42 and affecting the connection of the wire.

[0076] The above embodiments are merely preferred embodiments of this patent and are not intended to limit the scope of protection of this patent. Therefore, all equivalent changes made to the structure, shape, and principle of this patent should be included within the scope of protection of this patent.
