Description

Technical Field

[0001] This utility model relates to the field of scooter technology, and specifically to a folding structure for scooters. Background Technology

[0002] A scooter is a short-distance transportation tool that relies on the user to push off the ground to move forward. With the development of technology, electric scooters have also been invented. The structure of a scooter includes a base for pedaling and a front fork connected to the base. The front fork connects to the front wheel at the bottom, and a seat tube is located at the top of the fork, with a handlebar at the top. The seat tube is fixedly connected to the front fork, so it cannot be folded, making the scooter relatively bulky and inconvenient to store. The scooter rotates by rotating the handlebar on the seat tube, which in turn rotates the front fork and then the front wheel. However, the seat tube is typically a single rod connected to the connecting tube at the top of the front fork (a single-point connection), while the front fork connects to both ends of the front wheel axle. The front fork has two symmetrical mounting points at its bottom that connect to both ends of the axle. Therefore, the seat tube is not directly connected to the mounting points, but rather moves the two ends through a single-point connection, requiring a significant amount of force and resulting in unstable rotation. Summary of the Invention

[0003] The purpose of this invention is to provide a folding structure for scooters. By rotating the fork and the stem and using a limiting structure, folding is achieved and the folding is limited when not folded, thus ensuring that it will not fold during use. Secondly, the bottom of the mounting tube is rotatably mounted on the top of the mounting part, meaning that the stem is directly connected to the mounting part and drives the movement of the shaft end. Compared with existing designs, this invention applies less force and rotates more smoothly, thus solving the problems of existing designs that do not fold and have single-bar connections.

[0004] The purpose of this utility model is achieved as follows:

[0005] A folding structure for a scooter includes a front fork and a stem, wherein the front fork includes a connecting part, a connecting tube is provided at the top of the connecting part, and mounting parts are provided at both ends of the connecting part, and the bottom of the mounting part is connected to the end of the axle of the front wheel.

[0006] The riser includes two mounting pipes connected by an assembly pipe, and an assembly seat is provided between the two mounting pipes. The bottom of the mounting pipe is rotatably mounted on the top of the mounting part, and the top of the connecting pipe is located inside the assembly seat. The assembly seat is provided with a limiting structure, which is used to restrict the disconnection of the connecting pipe and thus restrict the rotation of the riser. By releasing the limiting structure and rotating the riser, the riser can be folded and the assembly seat and connecting pipe can be separated at the same time.

[0007] Preferably, the limiting structure includes a handle and a pressure block, and a groove 1 is provided on one side of the assembly base, and a groove 2 communicating with the groove 1 is provided at the bottom of the assembly base. The top of the connecting pipe is located in the groove 2, and a rotatable handle and a pressure block are provided in the groove 1.

[0008] The handle is connected to the pressure block and drives the pressure block to rotate. The pressure block is located on one side of the connecting tube.

[0009] Preferably, the handle has a limiting hole, and the limiting component includes a pin, which includes a connecting rod and a rotating rod, and the connecting rod is connected to the assembly base;

[0010] The rotating rod includes a limiting part and a rod located at the bottom of the limiting part, with the bottom of the rod passing through the connecting rod and protruding. The limiting part has a limiting block on the outside of the rod. The top of the connecting rod has a slot, and the limiting block is located in the slot, so that the bottom of the rod is located in the limiting hole, thereby restricting the rotation of the handle. By moving and rotating the rotating rod, the limiting block is separated from the slot and abuts against the top of the connecting rod, thereby separating the rod from the limiting hole and allowing the handle to rotate.

[0011] Preferably, the assembly base has a limiting groove and the pressure block has a limiting hole. The limiting component includes a pin, and the pin includes a moving rod and a cap. The cap is connected to the moving rod and drives the moving rod to move and rotate.

[0012] The cap has a protrusion on one side, and the bottom of the moving rod passes through the assembly base and is located in the second limiting hole, thereby restricting the rotation of the pressure block. By moving and rotating the cap, the moving rod is driven to move and rotate, and the protrusion is located in the limiting groove, thereby separating the moving rod from the second limiting hole and allowing the pressure block to rotate.

[0013] Preferably, the pressure block has a movable clamping block on the side near the connecting pipe, and an adjusting rod is threadedly connected to the other side of the pressure block. One end of the adjusting rod passes through the pressure block and abuts against the clamping block, while the other end of the adjusting rod is located outside the pressure block. By rotating the adjusting rod, the pressure block is pushed towards the connecting pipe and makes the pressure block fit against the connecting pipe.

[0014] Preferably, the pressure block has a groove on the side near the connecting pipe, and the clamping block has a connecting plate on the side near the pressure block. The connecting plate has an elongated hole. The connecting plate is located in the groove, and a fastener is inserted into the groove and located in the elongated hole. The fastener is connected to the pressure block.

[0015] Preferably, one end of the handle has a groove three, and this end of the handle is rotatably connected to the assembly base, and one end of the pressure block is located in the groove three, and this end of the pressure block is rotatably connected to the handle.

[0016] Preferably, there are two assembly tubes, and a support tube is provided between the two assembly tubes.

[0017] Preferably, the assembly base includes a main body and two fixed seats, and the main body and fixed seats are provided with arc-shaped grooves corresponding to the mounting tube. The main body and fixed seats are located on both sides of the mounting tube, and fasteners pass through the fixed seats and are connected to the main body to set the assembly base on the mounting tube.

[0018] Alternatively, the top of the mounting part is provided with a mounting plate, and the bottom of the mounting tube is provided with a mounting groove corresponding to the mounting plate, and a rotating shaft passes through the bottom of the mounting tube and the mounting plate to realize the connection between the mounting part and the mounting tube.

[0019] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0020] The bottom of the mounting tube of this utility model is rotatably mounted on the top of the mounting part, and the assembly base is connected to the connecting tube and is provided with a limiting structure. Therefore, by rotating between the fork and the riser and cooperating with the limiting structure, folding can be achieved and the riser can be limited when not folded, thereby ensuring that it will not fold during use. At the same time, the bottom of the mounting tube is rotatably mounted on the top of the mounting part, that is, the riser is directly connected to the mounting part and drives the movement of the shaft end. Compared with the prior art, this utility model applies less force and rotates more smoothly. Attached Figure Description

[0035] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0036] like Figures 1-7 As shown, the folding structure for a scooter includes a front fork 1 and a stem 2. The front fork 1 includes a connecting part 11, and a connecting tube 12 is provided at the top of the connecting part 11. Mounting parts 13 are provided at both ends of the connecting part 11, and the bottom of the mounting part 13 is connected to the end of the axle of the front wheel.

[0037] Meanwhile, the riser 2 includes two mounting pipes 21, which are connected by an assembly pipe 22. An assembly seat 3 is provided between the two mounting pipes 21. The bottom of the mounting pipe 21 is rotatably mounted on the top of the mounting part 13, and the top of the connecting pipe 12 is located inside the assembly seat 3. The assembly seat 3 is provided with a limiting structure, which is used to limit the disconnection of the connecting pipe 12 and thus limit the rotation of the riser 2.

[0038] Therefore, in actual use, by releasing the limiting structure and rotating the riser 2, the riser 2 can be folded while the assembly seat 3 and connecting pipe 12 are separated. Thus, by rotating the fork 1 and the riser 2 in conjunction with the limiting structure, folding is achieved and the riser is limited when not folded, thereby ensuring that it will not fold during use. At the same time, the bottom of the mounting pipe 21 is rotatably mounted on the top of the mounting part 13, meaning that the riser 2 is directly connected to the mounting part 13 and drives the movement of the shaft end. Compared with the prior art, the force applied by this invention is smaller and the rotation is more stable.

[0039] There are two assembly pipes 22, and a support pipe 23 is provided between the two assembly pipes 22 to ensure the stability of the riser 2 itself.

[0040] like Figures 1-7 As shown, the specific structure of the limiting structure is as follows: First, the limiting structure includes a handle 5 and a pressure block 6, and a groove 31 is provided on one side of the assembly base 3, and a groove 32 communicating with the groove 31 is provided at the bottom of the assembly base 3. The top of the connecting pipe 12 is located in the groove 32, and a rotatable handle 5 and a pressure block 6 are provided in the groove 31.

[0041] At the same time, the handle 5 is connected to the pressure block 6 and drives the pressure block 6 to rotate. The pressure block 6 is located on one side of the connecting tube 12. A limiting component for limiting rotation is provided between the handle 5 and the assembly base 3 or / and between the pressure block 6 and the assembly base 3.

[0042] Therefore, in actual use, the rotation of the handle 5 and / or the pressure block 6 is restricted by the limiting component, so that the top of the connecting pipe 12 is located in the groove 32 and cannot be disengaged, that is, the riser 2 cannot be rotated. By releasing the limiting component, the handle 5 and the pressure block 6 can be rotated. At this time, the handle 5 and the pressure block 6 no longer restrict the connecting pipe 12, so the riser 2 can be rotated, thereby driving the top of the connecting pipe 12 to disengage from the groove 32.

[0043] The structure of the limiting component varies. It can be that the handle 5 has a limiting hole 51, and the limiting component includes a pin 7. The pin 7 includes a connecting rod 71 and a rotating rod 72, and the connecting rod 71 is connected to the assembly base 3.

[0044] Meanwhile, the rotating rod 72 includes a limiting part 721 and a rod 722 located at the bottom of the limiting part 721. The bottom of the rod 722 passes through the connecting rod 71 and protrudes. The limiting part 721 provides a limiting block 723 on the outside of the rod 722. The connecting rod 71 has a slot 711 at the top.

[0045] Therefore, in actual use, the limiting block 723 is located in the slot 711 and the bottom of the rod 722 is located in the limiting hole 51, thereby restricting the rotation of the handle 5. By moving and rotating the rotating rod 72, the limiting block 723 is separated from the slot 711 and the limiting block 723 abuts against the top of the connecting rod 71, thereby separating the rod 722 from the limiting hole 51 and allowing the handle 5 to rotate.

[0046] Furthermore, the assembly base 3 has a hole 36, through which the connecting rod 71 passes and is threadedly connected to the hole 36.

[0047] Secondly, the limiting component can also be that the assembly base 3 has a limiting groove 33 and the pressure block 6 has a limiting hole 61. The limiting component includes a pin 8, and the pin 8 includes a moving rod 81 and a cap 82. The cap 82 is connected to the moving rod 81 and drives the moving rod 81 to move and rotate. A protrusion 821 is provided on one side of the cap 82.

[0048] Therefore, in actual use, the bottom of the moving rod 81 passes into the assembly base 3 and is located in the limiting hole 61, thereby restricting the rotation of the pressure block 6. By moving and rotating the cap 82, the moving rod 81 is moved and rotated, and the protrusion 821 is located in the limiting groove 33, thereby separating the moving rod 81 from the limiting hole 61 and allowing the pressure block 6 to rotate.

[0049] Furthermore, the assembly base 3 has a second hole 37, through which the moving rod 81 passes, and a spring can be provided between the moving rod 81 and the assembly base 3 to facilitate the reset of the moving rod 81.

[0050] like Figure 4 As shown, the pressure block 6 has a movable clamping block 9 on the side near the connecting pipe 12, and an adjusting rod is threadedly connected to the other side of the pressure block 6. One end of the adjusting rod passes through the pressure block 6 and abuts against the clamping block 9, while the other end of the adjusting rod is located outside the pressure block 6.

[0051] Therefore, in actual use, by rotating the adjusting rod, the pressure block 6 is pushed towards the connecting tube 12 and made to fit against the connecting tube 12. Thus, when not folded, the stability of the connection and the limiting position is ensured.

[0052] Furthermore, the moving structure between the pressure block 6 and the clamping block 9 is as follows: First, the pressure block 6 has a groove 62 on the side near the connecting pipe 12, and the clamping block 9 has a connecting plate 91 on the side near the pressure block 6. The connecting plate 91 has an elongated hole 911, and the connecting plate 91 is located inside the groove 62. A fastener is inserted into the groove 62 and located inside the elongated hole 911, and the fastener is connected to the pressure block 6. The fastener is a screw.

[0053] Therefore, in actual use, the fastener is connected to the pressure block 6 and located in the elongated hole 911, thereby preventing the pressure block 9 from detaching from the pressure block 6. When the adjusting rod moves the pressure block 6, the connecting plate 91 moves in the groove 62, and the fastener moves relative to the elongated hole 911 in the elongated hole 911.

[0054] like Figures 3-7As shown, the rotating structure of the handle 5 and the pressure block 6 is as follows: First, a groove 3 52 is opened at one end of the handle 5, and this end of the handle 5 is rotatably connected to the assembly base 3, that is, the rotatable connection between the assembly base 3 and the handle 5 is achieved by using two screws. The fact that the screw connection allows for rotation is existing technology, and because the tightness and gap of the screws can be adjusted, there is room for rotation.

[0055] Moreover, one end of the pressure block 6 is located in the groove 3 52, and this end of the pressure block 6 is rotatably connected to the handle 5, that is, the rotatable connection between the pressure block 6 and the handle 5 is achieved by using the rotating shaft 2 63.

[0056] like Figure 3 and Figure 4 As shown, the installation structure of the assembly base 3 is as follows: First, the assembly base 3 includes a main body 34 and two fixing seats 35. The main body 34 and the fixing seats 35 are provided with arc-shaped grooves corresponding to the mounting tube 21. The main body 34 and the fixing seats 35 are located on both sides of the mounting tube 21. Fasteners 2 pass through the fixing seats 35 and are connected to the main body 34, thereby setting the assembly base 3 on the mounting tube 21. The fasteners 2 are screws.

[0057] At the same time, such as Figure 2 As shown, the structure between the mounting part 13 and the mounting tube 21 is as follows: First, a mounting plate 131 is provided on the top of the mounting part 13, and a mounting groove 211 is opened at the bottom of the mounting tube 21 corresponding to the mounting plate 131. A rotating shaft passes through the bottom of the mounting tube 21 and the mounting plate 131 to realize the connection between the mounting part 13 and the mounting tube 21.

[0058] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. However, this utility model is not limited to the above embodiments; therefore, various changes and modifications can be made without departing from the principles and scope of this utility model, and all such changes and modifications fall within the scope of the claimed utility model.
