Description

Technical Field

[0001] This utility model relates to the field of self-balancing scooters, and more particularly to a self-balancing scooter with quick-release handlebars. Background Technology

[0002] Self-balancing scooters, as a popular personal short-distance transportation tool, are widely welcomed by users for their flexibility and environmental friendliness. To improve the comfort and convenience of handling, many self-balancing scooters are equipped with handlebars or grips for users to hold onto.

[0003] In existing technologies, there are two main ways to connect the handlebars of self-balancing scooters to the scooter body: one is a fixed connection, where the handlebars are permanently fixed to the body using screws or other fasteners; the other is a simple detachable connection. While fixed handlebars offer structural stability, they result in a bulky overall size for the scooter, making them inconvenient to transport and store, especially in car trunks or corners of the home, where they take up considerable space. Existing detachable handlebars, while solving the storage problem to some extent, are typically cumbersome to remove. A common practice is to require users to use additional tools (such as Allen wrenches) to loosen multiple screws to remove the handlebars. This process is not only time-consuming and laborious, but small parts like screws are also prone to being lost or improperly stored after disassembly, leading to inconvenience during reinstallation. Furthermore, some handlebars using simple plug-and-play structures generally suffer from unstable connections and a wobbly feel, affecting the user experience and sense of safety.

[0004] Therefore, the market urgently needs a self-balancing scooter that can ensure a secure and reliable connection while also enabling quick disassembly and installation. Utility Model Content

[0005] The main purpose of this utility model is to provide a balance scooter with quick-release handlebars, which aims to solve the technical problems of difficult folding and storage of balance scooter handlebars, unstable connection, and wobbling.

[0006] To achieve the above objectives, this utility model provides a balance scooter with a quick-release handlebar, comprising: a handlebar assembly including a handlebar stem, the handlebar stem having a pressing hole and a locking hole; a frame upper shell, internally provided with a connector that mates with the handlebar stem; a quick-release assembly disposed within the handlebar stem, including an elastic element and a quick-release component, the quick-release component including a pressure plate, a locking button, and a hook block, the elastic element and the pressure plate being disposed within the handlebar stem, the elastic element pressing the pressure plate against the inner wall of the handlebar stem, and the locking button... A button is located on the side of the pressure plate opposite to the elastic element, and a hook is located on the side of the pressure plate opposite to the elastic element. The hook passes through the locking hole and presses against the bottom of the side wall of the handle riser and the insertion tube. The locking button and the hook can extend or retract synchronously from the pressing hole and the locking hole under the action of the elastic element. When disassembling, pressing the locking button makes the quick-release assembly completely inside the handle riser, and then pulling out the handle riser separates the handle riser and the insertion tube.

[0007] Preferably, the handle assembly further includes grip sleeves and a handle tube, the handle tube being disposed at the top end of the handle riser, and a pair of grip sleeves being sleeved on both ends of the handle tube.

[0008] Preferably, the handle tube is provided with a plurality of first length adjustment holes, and the handle riser is provided with a plurality of second length adjustment holes corresponding to the first length adjustment holes. Any one of the first length adjustment holes can be aligned and locked with any one of the second length adjustment holes to adjust the height of the handle assembly.

[0009] Preferably, the pressure plate has a cross-shaped protrusion on the side near the elastic member, one end of the elastic member abuts against the handle riser tube, and the other end abuts against the periphery of the cross-shaped protrusion.

[0010] Preferably, it also includes a lower frame shell, which is disposed at the bottom of the upper frame shell. The lower frame shell has a first annular groove that matches the shape of the handlebar riser port, and the handlebar riser is inserted into the first annular groove.

[0011] Preferably, the lower shell of the frame is provided with a second annular groove that matches the shape of the connector tube, and the connector tube is inserted into the second annular groove.

[0012] Preferably, the insertion tube is provided with a sliding notch for the hook block to slide, and a limiting part is provided in the sliding notch, and the hook block abuts against the limiting part.

[0013] Preferably, the hook block includes a pressing surface and a sliding surface. The pressing surface contacts the inner wall of the clamping hole and the limiting part. The sliding surface is located at the end opposite to the pressing surface. The angle between the sliding surface and the pressing surface is less than or equal to 45°.

[0014] Preferably, the elastic element includes a spring and a cylinder.

[0015] Preferably, a pair of the cross protrusions are located at both ends of the pressure plate, and a pair of elastic members are respectively supported on the two cross protrusions.

[0016] In the technical solution provided by this utility model, in the locked state, the built-in elastic element continuously applies pressure to the pressure plate, forcing the hook block on the quick-release component to extend outward and pass through the locking hole on the handlebar stem, ultimately firmly pressing against the bottom end of the side wall of the frame connector tube, forming a rigid connection. This effectively prevents shaking during use and ensures the stability and safety of the handlebar. When disassembly is required, the user only needs to press the locking button with one hand. The button pushes the pressure plate to move inward against the elastic force of the elastic element, and simultaneously drives the hook block to retract from the locking hole, so that the quick-release component is completely housed in the handlebar stem tube. At this time, the mechanical lock between the handlebar stem tube and the frame connector tube is released, and the two can be easily separated. This mechanism enables the handrail to be truly "one-click" quick-release, requiring no tools and making the operation extremely simple and fast. At the same time, all key components are concealed within the handrail uprights, resulting in a compact structure and simple appearance. While providing a stable experience similar to fixed handrails, it also greatly facilitates the storage and transportation of the balance bike, completely resolving the contradiction between portability and stability in traditional handrails.

[0023] Please refer to Figures 1 to 4 This utility model provides a balance scooter with quick-release handlebars, including: a handlebar assembly 1, including a handlebar stem 11, the handlebar stem 11 having a pressing hole 111 and a locking hole 112; a frame upper shell 2, with an insert tube 21 that mates with the handlebar stem 11; and a quick-release assembly 3, disposed inside the handlebar stem 11, including an elastic element 31 and a quick-release element 32, the quick-release element 32 including a pressure plate 321, a locking button 322 and a hook block 323, the elastic element 31 and the pressure plate 321 being disposed inside the handlebar stem 11, the elastic element 31 pressing the pressure plate 321 against the inner wall of the handlebar stem 11, and the locking button 323... 2 is set on the side of the pressure plate 321 away from the elastic element 31, and the hook block 323 is set on the side of the pressure plate 321 away from the elastic element 31. The hook block 323 passes through the locking hole 112 and presses against the bottom end of the side wall of the handle riser tube 11 and the insertion tube 21. The locking button 322 and the hook block 323 can extend or retract synchronously under the action of the elastic element 31 to press the hole 111 and the locking hole 112. When disassembling, press the locking button 322 to make the quick release assembly 3 completely inside the handle riser tube 11, and then pull out the handle riser tube 11 to separate the handle riser tube 11 and the insertion tube 21. The elastic element 31 includes a spring and a cylinder.

[0024] In the technical solution provided by this utility model, in the locked state, the built-in elastic element 31 continuously applies pressure to the pressure plate 321, forcing the hook block 323 on the quick-release component 32 to extend outward and pass through the locking hole 112 on the handlebar stem 11, ultimately firmly pressing against the bottom side wall of the frame connector tube 21 to form a rigid connection. This effectively prevents shaking during use and ensures the stability and safety of the handlebar. When disassembly is required, the user only needs to press the locking button 322 with one hand. The button pushes the pressure plate 321 to move inward against the elastic force of the elastic element 31, and simultaneously drives the hook block 323 to retract from the locking hole 112, so that the quick-release component 3 is completely housed in the handlebar stem 11. At this time, the mechanical lock between the handlebar stem and the frame connector tube 21 is released, and the two can be easily separated. This mechanism enables the handrail to be truly "one-click" quick-release, requiring no tools and making the operation extremely simple and fast. At the same time, all key components are concealed within the handrail uprights, resulting in a compact structure and simple appearance. While providing a stable experience similar to fixed handrails, it also greatly facilitates the storage and transportation of the balance bike, completely resolving the contradiction between portability and stability in traditional handrails.

[0025] Please refer to Figures 1 to 4In this embodiment, the handle assembly 1 further includes grip sleeves 12 and handle tubes 13. The handle tube 13 is disposed at the top of the handle riser 11, and a pair of grip sleeves 12 are fitted onto both ends of the handle tube 13. By providing a horizontal handle tube 13 at the top of the handle riser 11 and fitting grip sleeves 12 at both ends, a comfortable ergonomic grip is provided for the user, effectively improving the comfort and stability of the balance vehicle. The traditional design separates the riser support and horizontal grip functions, with the handle riser 11 providing the main support, while the handle tubes 13 and grip sleeves 12 are specifically optimized for a better grip, making the overall handle assembly 1 structurally sound and easy to operate.

[0026] Please refer to Figures 1 to 4 In this embodiment, the handle tube 13 is provided with a plurality of first length adjustment holes 131, and the handle riser tube 11 is provided with a plurality of second length adjustment holes 132 corresponding to the first length adjustment holes 131. Any first length adjustment hole 131 can be aligned and locked with any second length adjustment hole 132 to adjust the height of the handle assembly 1. By changing the alignment position of the first and second length adjustment holes 132 and fixing them with locking parts (such as screws) passing through the aligned holes, stepless or multi-level adjustment of the overlap length between the handle riser tube 11 and the handle tube 13 is achieved, ultimately changing the usable height of the entire handle assembly 1.

[0027] Please refer to Figures 1 to 4 In this embodiment, the pressure plate 321 has a cross-shaped protrusion on the side near the elastic member 31. One end of the elastic member 31 presses against the handle riser 11, and the other end presses against the periphery of the cross-shaped protrusion 321. This provides a precise positioning and support point for the elastic member 31 (such as a spring), effectively preventing the elastic member 31 from skewing or misaligning during compression and rebound, ensuring the stability of the direction of the force of the quick-release assembly 3 and the efficiency of its transmission, improving the smoothness of operation and the service life of the components. The structure of the cross-shaped protrusion naturally forms a limiting area on its periphery, and one end of the elastic member 31 is reliably restricted within this area, thus maintaining centering during the reciprocating motion of the pressure plate 321.

[0028] Please refer to Figures 1 to 4In this embodiment, a lower frame shell 4 is also included. The lower frame shell 4 is disposed at the bottom of the upper frame shell 2. The lower frame shell 4 is provided with a first annular groove 41 that matches the shape of the handlebar riser tube 11 port. The handlebar riser tube 11 is inserted into the first annular groove 41. By providing a first annular groove 41 on the lower frame shell 4 that matches the shape of the handlebar riser tube 11 port, a precise insertion and positioning base is provided for the bottom of the handlebar riser tube 11, enhancing the overall structural stability and anti-shaking ability of the handlebar after installation. When the handlebar riser tube 11 is inserted into the insertion tube 21 of the upper frame shell 2 and finally abuts against the first annular groove 41, the annular groove wraps around and constrains the port of the handlebar riser tube 11 from the bottom, forming multiple positioning from top to bottom, effectively dispersing the force and preventing the base of the handlebar from swaying due to force.

[0029] Please refer to Figures 1 to 4 In this embodiment, the lower frame shell 4 is provided with a second annular groove 42 that matches the shape of the insertion tube 21, and the insertion tube 21 is inserted into the second annular groove 42. By providing a second annular groove 42 on the lower frame shell 4 that matches the shape of the insertion tube 21, the lower end of the insertion tube 21 is firmly positioned and fixed on the lower frame shell 4, thereby enhancing the rigidity and strength of the insertion tube 21, the core load-bearing structure in the upper frame shell 2, making the armrest installation more stable; the lower end of the insertion tube 21 is embedded in the second annular groove 42, and this structure effectively transmits and distributes the lateral force and bending moment from the armrest borne by the insertion tube 21 to the more robust lower frame shell 4, forming a reliable reinforced support. It also works together with the first annular groove 41 to provide precise positioning.

[0030] Please refer to Figures 1 to 4 In this embodiment, the insertion tube 21 is provided with a sliding notch 211 for the hook block 323 to slide. A limiting part 212 is provided in the sliding notch 211, and the hook block 323 presses against the limiting part 212. When the handrail riser is inserted, the hook block 323 slides along the sliding notch 211 until it contacts the limiting part 212. At this time, the limiting part 212 acts as a solid mechanical blocking surface. The hook block 323 presses tightly against this surface under the pressure of the elastic member 31, thereby rigidly locking the handrail riser and the insertion tube 21 together.

[0031] Please refer to Figures 1 to 4In this embodiment, the hook block 323 includes a pressing surface 3231 and a sliding surface 3232. The pressing surface 3231 contacts the inner wall of the clamping hole 112 and the limiting part 212. The sliding surface 3232 is located at one end away from the pressing surface 3231. The angle between the sliding surface 3232 and the pressing surface 3231 is less than or equal to 45°. By designing the included angle between the sliding surface 3232 and the top pressing surface 3231 of the hook block 323 to be less than or equal to 45°, the hook block 323 can slide back from the locked position more smoothly when disassembling the handrail, greatly reducing the pressing force and jamming phenomenon required for operation, and achieving a more effortless and smoother "one-click disassembly" experience; when the locking button 322 is pressed, the hook block 323 is driven to retract, and its inclined sliding surface 3232 contacts the limiting part 212 or the hole wall on the insertion tube 21 and generates a radial component force that makes it easier for the hook block 323 to slide in, thereby effectively reducing the sliding friction resistance.

[0032] Please refer to Figures 1 to 4 In this embodiment, a pair of cross protrusions 3211 are respectively disposed at both ends of the pressure plate 321, and a pair of elastic members 31 are respectively supported on the two cross protrusions 3211. This effectively prevents the pressure plate 321 from tilting, jamming, or abnormally wearing due to unilateral force during movement, ensuring the smoothness and stability of the quick-release action.

[0033] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Under the concept of this utility model, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of different aspects of this utility model as described above. For the sake of brevity, they are not provided in detail. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
