Description

Technical Field

[0001] This utility model relates to the field of lifting structure technology, and in particular to a lifting structure without an external tube, which can be applied to electric scooters. The lifting structure is connected to the handlebar assembly to drive the handlebar assembly to lift and lower, allowing the user to ride at a better height. Background Technology

[0002] Scooters are a common form of transportation, consisting of a footboard between the front and rear wheels for the user to stand on. The user propels the scooter forward by pushing off with one foot, but prolonged pedaling can easily lead to fatigue. Therefore, electric scooters use batteries and motors to power their movement. When the user is tired, simply turning the ignition switch activates the motor, providing a more relaxed riding experience.

[0003] Some scooters offer adjustable handlebars, allowing users of different heights to adjust the height of the handlebar assembly for a comfortable standing posture. Patent No. 437673 discloses an improvement to a scooter handlebar height adjustment device, which releases the quick-release sleeve, allowing the outer tube to release its fixation on the bushing and handlebar vertical tube, enabling the handlebar vertical tube to move freely up and down, thus adjusting the handlebar to the desired height.

[0004] Because modern electric scooters use throttle grips in their handlebar structure, a cable needs to be run from the battery to the throttle grip to transmit a signal to the battery when the throttle grip is turned. Typically, the wiring connects to the throttle grip through the hollow area of ​​the upper tube. However, if the traditional lifting structure of the aforementioned patent is applied to an electric scooter, the wiring would run through both the handlebar vertical tube and the outer tube. Therefore, during the movement of the handlebar vertical tube, the wiring could get stuck at the junction of the handlebar vertical tube and the outer tube, making the handlebar vertical tube difficult to adjust and potentially shortening the lifespan of the wiring due to constant friction between the handlebar vertical tube and the wiring.

[0005] Therefore, the applicant considered how to provide a lifting structure that allows for smooth adjustment of the handlebars of an electric scooter. Utility Model Content

[0006] Given that the existing lifting structures still have many defects, the main purpose of this utility model is to provide a lifting structure without an external tube, so that users can adjust the height more smoothly.

[0007] To achieve the aforementioned main objectives, this utility model provides a tubeless lifting structure, comprising an upper tube, an adapter sleeve, and a fixing assembly. The upper tube has a first connecting portion and a quick-release unit. The first connecting portion forms a through hole for fitting the upper tube, and the quick-release unit is assembled to the first connecting portion. Operating the quick-release unit tightens or loosens the upper tube at the first connecting portion. The fixing assembly is assembled to the adapter sleeve and adjacent to the first connecting portion. The fixing assembly has an operating component and an actuating rod. The actuating rod is movably disposed on the operating component and also passes through the adapter sleeve. The operating component can move the actuating rod between a first position and a second position. In the first position, the actuating rod engages with the upper tube to fix its position; in the second position, the actuating rod disengages from the upper tube to release the fixation of the upper tube's position.

[0008] Through the aforementioned technical features, the upper tube of this invention no longer needs to be inserted into the outer tube, allowing for independent adjustment of its position. The wiring inside the upper tube will not interfere with its movement, enabling smooth adjustment of the height of the handle assembly connected to the upper tube. Traditional lifting structures only use a quick-release mechanism to fix the upper tube's position. This invention, in addition to a quick-release unit for tightening or loosening the upper tube, further provides a fixing component. When the quick-release unit is unlocked, and the operating component moves the actuating lever to the second position, the user can then adjust the upper tube. This achieves a two-stage unlocking mechanism, preventing accidental lowering of the upper tube due to accidental contact with the quick-release unit.

[0009] Preferably, one end of the first joint of the adapter sleeve has two joint sections, and one end of the quick-release unit is provided with a pivot. A connecting shaft passes through these joint sections and is then fixed to the pivot, allowing the quick-release unit to pivot relative to the first joint. Therefore, the user can tighten or loosen the upper tube by operating the quick-release unit.

[0010] Preferably, the adapter sleeve also has a second connecting portion forming a circular groove to accommodate the lower tube. The second connecting portion also has a slot, with at least one clamping member connecting the walls on both sides of the slot. Thus, the lower tube is secured by clamping, allowing it to be reconnected to the fork.

[0011] Preferably, the operating component of the fixing assembly includes a handle, a slider, an elastic element, an elastic element fixing seat, and a pin. The handle is connected to the slider and can move relative to the adapter sleeve. The elastic element is housed in the elastic element fixing seat, which is fixed to the adapter sleeve. The pin passes through the actuating rod, with one side of the pin abutting one end of the slider and the other side abutting the elastic element. The handle can drive the slider to move, which in turn drives the pin to move, causing the actuating rod to move from a first position to a second position. Therefore, the handle, slider, pin, and actuating rod are interconnected, allowing the user to easily operate the handle to change the position of the actuating rod. When the user releases the handle, the elastic element's rebound force can automatically return the actuating rod from the second position to the first position.

[0012] Preferably, a groove is formed on the outer peripheral surface of the handle. This provides the user with a convenient position to apply force, allowing the handle to be operated easily.

[0013] Preferably, one end of the slider protrudes to form two hooks, which abut against one side of the pin. Therefore, the slider and the pin are linked to smoothly drive the pin to move.

[0014] Preferably, the operating component of the fixing assembly further includes a limiting member, and a limiting groove is formed in the sliding member, with the limiting member passing through the limiting groove and the adapter sleeve. Therefore, when the actuating lever moves between the first position and the second position, the range of movement of the operating component can be limited, preventing the operating component from accidentally separating from the adapter sleeve.

[0015] Preferably, a flat portion is formed on one side of the outer peripheral surface of the upper tube, and multiple insertion holes are provided in the flat portion. When the actuating rod of the fixing component is in the first position, one end is inserted into any one of the insertion holes. Therefore, the upper tube can be adjusted to a suitable height according to the insertion position of the actuating rod.

[0016] The detailed structure, features, assembly, and usage of the tubeless lifting structure provided by this utility model will be described in the subsequent detailed description of the embodiments. However, those skilled in the art will understand that these detailed descriptions and the specific embodiments listed for implementing this utility model are for illustrative purposes only and are not intended to limit the scope of protection of this utility model.

[0062] Please see Figures 1 to 5 The tubeless lifting structure provided by this utility model mainly includes an upper tube 10, a connecting sleeve 20 and a fixing component 30, which can be combined with an electric scooter 40.

[0063] The upper tube 10 is a hollow tube body, with a flat portion 11 formed on one side of its outer circumference, and multiple insertion holes 12 formed in the flat portion 11. A handle assembly 41 is connected to the top end of the upper tube 10. The ignition grip of this handle assembly 41 is electrically connected to the electronic control system of the electric scooter 40 via a wire 42, which can be run through the interior of the upper tube 10. Since the main technical feature of this utility model is for adjusting the lifting structure of the upper tube 10, therefore... Figure 1 The electric scooter 40 in the picture does not specifically show the throttle handle, electronic control system or pedals.

[0064] The adapter sleeve 20 is L-shaped and has a first connecting portion 21, a quick-release unit 22, and a second connecting portion 23. The first connecting portion 21 is formed at one end of the adapter sleeve 20 and has a through hole 211 and two connecting sections 212. The through hole 211 penetrates the top and bottom ends of the first connecting portion 21, while the two connecting sections 212 are formed on the sides of the first connecting portion 21, with a distance between them. A pivot 221 is provided at one end of the quick-release unit 22. A connecting shaft 24 passes through the two connecting sections 212 of the first connecting portion 21 and is then fixed to the pivot 221, so that the quick-release unit 22 is pivotally connected to the first connecting portion 21. The second connecting portion 23 is formed at the other end of the adapter sleeve 20 and has a circular groove 231. A slot 232 is also formed on the side of the second connecting portion 23.

[0065] In this design, the upper tube 10 of the electric scooter 40 passes through the through hole 211 of the first joint 21. The user can change the distance between the two joint sections 212 by moving the quick-release unit 22, so that the first joint 21 can tighten or loosen the upper tube 10. The lower tube of the electric scooter 40 passes through the circular groove 231 of the second joint 23. Two clamping members 25 are then used, for example, bolts, to connect the walls on both sides of the groove 232. After tightening the bolts, the walls on both sides of the groove 232 move closer to each other, thereby tightening and fixing the lower tube.

[0066] The fixing component 30 is assembled to the adapter sleeve 20. A recessed area is formed on the side of the adapter sleeve 20 adjacent to the first joint 21 to provide space for the fixing component 30. The fixing component 30 has an operating part 31 and an actuating lever 32. The operating part 31 of the fixing component 30 has a handle 311, a slider 312, an elastic element 313, an elastic element fixing seat 314, and a pin 315. The outer peripheral surface of the handle 311 is recessed to form a groove 3111. The slider 312 is bolted to the handle 311, and the slider 312 has two hooks 3121 formed at one end of the slider 312. The elastic element 313 is a spring, which is received in the receiving groove 3141 of the elastic element fixing seat 314, and the elastic element fixing seat 314 is fixed to the screw hole 28 of the adapter sleeve 20 by a screw 3142. One end of the actuating rod 32 is inserted into the spring, and the other end passes through the inner hole 26 of the adapter sleeve 20 and faces the flat portion 11 of the upper tube 10, with a pin hole 321 formed in the actuating rod 32. The pin 315 is inserted into the pin hole 321 of the actuating rod 32, and one side of the pin 315 abuts against the two hooks 3121 of the sliding member 312, while the other side abuts against the elastic member 313. In this way, by pulling the handle 311, the sliding member 312 can be moved, and the sliding member 312 then moves the pin 315. The pin 315 compresses the spring, which in turn moves the actuating rod 32, causing the actuating rod 32 to move from the first position P1 to the second position P2.

[0067] To limit the movement distance of the actuating lever 32 and prevent the handle 311 of the operating component 31 from separating from the sliding member 312 via the rotating sleeve 20, the operating component 31 also has a limiting member 33. A limiting groove 3122 is formed on both sides of the sliding member 312, and a side hole 27 is formed on the rotating sleeve 20 corresponding to the limiting groove 3122. The limiting member 33 passes through both the side hole 27 of the rotating sleeve 20 and the limiting groove 3122 of the sliding member 312. When the actuating lever 32 moves between the first position P1 and the second position P2, the limiting member 33 remains stationary, while the limiting groove 3122 moves along the limiting member 33. The length of the limiting groove 3122 is the distance the actuating lever 32 can move.

[0068] Please refer to this document as well. Figure 6 When the quick-release unit 22 of the adapter sleeve 20 is in the tightened state and the actuating rod 32 of the fixing component 30 is in the first position P1, the actuating rod 32 is inserted into the insertion hole 12 at the bottom of the upper tube 10, so that the upper tube 10 is fixed and cannot be moved.

[0069] When the user needs to store the electric scooter 40 or adjust the height of the handlebar assembly 41, first, the quick-release unit 22 of the adapter sleeve 20 is activated to increase the distance between the two connecting sections 212 of the first connecting part 21, thereby relieving the clamping force on the upper tube 10. Then, the user operates the handle 311 of the operating part 31 of the fixing assembly 30. Simply place your finger in the groove 3111 of the handle 311 and pull outwards to move the handle 311. Since the elastic element fixing seat 314 is fixed to the adapter sleeve 20, the elastic element fixing seat 314 will not move, while the sliding element 312, pin 315, and actuating rod 32 will move simultaneously. The elastic element 313 is compressed by the pin 315, and one end of the actuating rod 32 separates from the insertion hole 12 at the bottom of the upper tube 10, moving from the first position P1 to the second position P2. Figure 7 As shown. At this time, the upper tube 10 can move freely up and down. The user can press down the handle assembly 41 to drive the upper tube 10 to move downward along the through hole 211 of the adapter sleeve 20. The end of the action rod 32 facing the upper tube 10 will be against the flat part 11. When the insertion hole 12 at the top of the upper tube 10 is aligned with the action rod 32, the elastic element 313 of the fixing assembly 30 will use the rebound force to push the pin 315, so that the action rod 32, the sliding element 312 and the pull handle 311 will automatically return to their original positions, that is, move from the second position P2 to the first position P1 to fix the position of the upper tube 10. Finally, the user can pull the quick release handle to make the first joint 21 tighten the upper tube 10 again, improving the fixing effect of the upper tube 10.

[0070] Although the above embodiment uses only two insertion holes 12, respectively located at the top and bottom of the upper tube 10, they are mainly used for the use and storage of the electric scooter 40. However, this utility model does not limit the number of insertion holes 12. If multiple equidistant insertion holes 12 are formed on the flat part 11 of the upper tube 10, the actuating rod 32 of the fixing component 30 can be inserted into different insertion holes 12, and the upper tube 10 can be fixed in different positions, so that the handle assembly 41 can be adjusted to multiple heights to suit users of various heights. In addition, if the upper tube 10 is not equipped with insertion holes 12, the actuating rod 32 of the fixing component 30 can also directly abut against the outer peripheral surface of the upper tube 10. Since the adapter sleeve 20 is provided with a quick-release unit 22, it also has a fixing effect on the upper tube 10 and can adjust the handle assembly 41 to the required height more quickly.

[0071] In summary, the tubeless lifting structure provided by this utility model has at least the following advantages compared with the prior art:

[0072] 1. The external tubeless lifting structure provided by this utility model utilizes the combination of the adapter sleeve 20 and the fixing component 30 to allow the upper tube 10 to move up and down independently, so as to achieve the function of adjusting the position of the upper tube 10. The wiring 42 passing through the upper tube 10 will not be interfered with by other components, thus avoiding the chance of the wiring 42 being worn.

[0073] 2. The external tubeless lifting structure provided by this utility model uses the quick-release unit 22 and the fixing component 30 of the adapter sleeve 20 to achieve a double fixing effect on the upper tube 10. Only when both the quick-release unit 22 and the fixing component 30 are released from fixing the upper tube 10 can the upper tube 10 move freely up and down, avoiding the situation where the upper tube 10 suddenly drops and causes danger.

[0074] Finally, it must be stated again that the constituent elements disclosed in the above embodiments of this utility model are merely illustrative examples and are not intended to limit the scope of protection of this utility model. Substitutions or variations of other equivalent elements should also be covered by the scope of protection of this utility model.
