Description

Technical Field

[0001] This utility model relates to the field of electric scooter technology, and more specifically, to a handlebar detachment and assembly structure for an electric scooter. Background Technology

[0002] The handlebars of an electric scooter are one of the widest parts of the scooter. The fixed handlebars mean that the scooter still occupies a large amount of lateral space when folded. To facilitate carrying and transportation, the handlebars need to be disassembled and reassembled.

[0003] Traditional electric scooter handlebar disassembly mechanisms often require users to bend down or squat to see and operate the screws or quick-release levers. This "downward operation" posture is very uncomfortable and inconvenient. Structures using numerous hexagonal screws and other fasteners require specialized tools (such as hex wrenches), which users easily forget to bring, making it impossible to disassemble the handlebars on-site when needed, thus reducing convenience. Furthermore, the screws on existing electric scooter handlebars are exposed outdoors. These exposed screws (especially ordinary steel screws) are easily oxidized and corroded when exposed to rain, moisture, dust, and salt (in coastal areas or areas where salt is applied in winter). Corroded screws can seize up and become difficult to disassemble.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a handlebar detachment and assembly structure for electric scooters, aiming to solve the technical problem of inconvenient handlebar detachment and assembly.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a handlebar assembly / disassembly structure for an electric scooter, comprising a scooter body and a pole fixedly installed at the front end of the scooter body, a handlebar being provided at the top of the pole, a threaded hole being provided at the top of the pole along the axial centerline, a positioning groove being provided at the bottom of the handlebar, the top of the pole being movably inserted into the positioning groove, a through hole corresponding to the threaded hole being provided at the top of the positioning groove, a hand-tightening bolt being movably connected in the through hole, the handlebar being inserted into the top of the pole through the positioning groove at its bottom end, and the hand-tightening bolt being threaded through the through hole and threadedly connected to the threaded hole in sequence, thereby achieving the fixed installation of the handlebar and the pole.

[0007] The present invention is further configured such that: the upright is cylindrical in shape, and its top cross-section is an irregular cross-section that is straight in the left and right direction and curved in the front and back direction. The cross-sectional shape of the positioning groove is completely matched with the cross-sectional shape of the top of the upright to achieve circumferential positioning.

[0008] The present invention is further configured such that: a groove is provided at the top of the handlebar, and two limiting grooves are symmetrically provided on the left and right side walls of the middle part of the groove; a sealing cap is movably inserted into the opening end of the groove by an interference fit; two handle grooves are provided on the outer surface of the sealing cap; and the outer circumferential surface of the sealing cap is in frictional contact with the inner wall of the groove to achieve detachable fixing.

[0009] The present invention is further configured such that the sealing cap is made of an elastic material.

[0010] The present invention is further configured such that: the head of the hand-tightening bolt is located in the groove, and two opposing hand-tightening handles are fixed on the head surface of the hand-tightening bolt; extension handles are movably inserted through the opposite sides of the two hand-tightening handles, and a lever is fixed at the top of the extension handle.

[0011] In summary, this utility model has the following beneficial effects:

[0012] 1. By centrally arranging all operating parts (hand-tightening bolts, hand-tightening handles, and extension handles) in the groove at the top of the handlebars, users can operate while standing upright, whether installing or disassembling. Their line of sight is naturally downward, allowing them to clearly see the operating area without any bending or squatting. This "top operation" method greatly enhances the ergonomic experience, making the operation process more comfortable and convenient.

[0013] 2. With the integrated design of the hand-tightening bolt and handle, users can complete basic tightening and loosening operations by hand. For situations requiring greater torque, the built-in extension handle provides additional lever arm, further reducing the demand on hand strength. The entire process requires no external tools, improving the convenience of disassembling and assembling the handlebars. The hand-tightening bolt and its connection parts are completely covered and sealed by a removable elastic sealing cap. The sealing cap is made of elastic materials such as silicone and rubber, forming a tight interference fit with the groove, which can effectively block the intrusion of rainwater, moisture, dust, gravel and salt spray, preventing the oxidation and corrosion of metal parts and protecting them, thus facilitating disassembly and assembly.

[0023] The present invention will now be described in detail with reference to the accompanying drawings.

[0024] A handlebar detachment structure for an electric scooter, such as Figures 1 to 5As shown, the vehicle includes a body 1 and a pole 2 fixedly installed at the front end of the body 1. A handlebar 3 is provided at the top of the pole 2. A threaded hole 4 is opened at the top of the pole 2 along the axial centerline. A positioning groove 5 is opened at the bottom of the handlebar 3. The top of the pole 2 is movably inserted into the positioning groove 5. A through hole 6 corresponding to the threaded hole 4 is opened at the top of the positioning groove 5. A hand-tightening bolt 7 is movably connected in the through hole 6. The handlebar 3 is inserted and engaged with the top of the pole 2 through the positioning groove 5 at its bottom end, and the hand-tightening bolt 7 passes through the through hole 6 in sequence and is threadedly connected to the threaded hole 4, thereby realizing the fixed installation of the handlebar 3 and the pole 2.

[0025] like Figure 2 As shown, the upright 2 is cylindrical in shape, with an irregular cross-section at its top that is straight in the left-right direction and curved in the front-back direction. The cross-sectional shape of the positioning groove 5 perfectly matches the cross-sectional shape at the top of the upright 2 to achieve circumferential positioning. When the traditional circular upright 2 and circular positioning groove 5 are matched, the handlebar 3 may rotate at any angle after installation, causing the handlebar 3 to be skewed, affecting handling safety and aesthetics. The core function of this design is to achieve circumferential positioning (anti-rotation) between the handlebar 3 and the upright 2. The handlebar 3 can only be inserted in one correct direction during installation, ensuring that the handlebar 3 is in the correct centered and horizontal position after each installation, avoiding directional deviation caused by incorrect installation.

[0026] like Figure 1 He Ru Figure 3 As shown, a groove 8 is provided at the top of the handlebar 3. Two limiting grooves 9 are symmetrically provided on the left and right side walls of the middle of the groove 8. A sealing cover 10 is movably inserted into the opening end of the groove 8 by an interference fit. Two handle slots 11 are provided on the outer surface of the sealing cover 10. The outer peripheral surface of the sealing cover 10 is in frictional contact with the inner wall of the groove 8 to achieve detachable fixation. The groove 8 serves as a space for the internal operating mechanism (hand-tightening bolt 7, extension handle 13, etc.) to achieve hidden integration of components. The handle slots 11 are recessed structures on the outer surface of the sealing cover 10 to provide functional grip points. The sealing cover 10 completely seals the key fasteners such as the hand-tightening bolt 7, effectively isolating rainwater, dust, mud and salt spray.

[0027] The sealing cap 10 is made of an elastic material. By utilizing the deformation properties of the elastic material (such as silicone or rubber), the sealing cap 10 can be tightly "inserted" into the groove 8 and fixed by friction. This allows for tool-free and reusable disassembly and assembly. The sealing cap 10 covers and seals the opening of the groove 8, protecting the internal precision components.

[0028] like Figure 5As shown, the head of the hand-tightening bolt 7 is located in the groove 8, and two opposing hand-tightening handles 12 are fixed to the surface of the head of the hand-tightening bolt 7. Extension handles 13 are movably inserted through the opposite sides of the two hand-tightening handles 12, and a lever 14 is fixed to the top of each extension handle 13. The hand-tightening bolt 7, as the core fastener, achieves detachable fixing of the handlebar 3 and the stem 2 through a threaded connection. The hand-tightening handles 12, fixed to the bolt head, provide a gripping point for hand operation, enabling tool-free assembly and disassembly. Users do not need to carry special tools such as Allen wrenches; they can complete the installation and disassembly of the handlebar 3 using the hand-tightening handles 12, solving the pain point of "reliance on tools" and greatly improving convenience. When encountering significant resistance... When the user lacks sufficient strength, after manually turning the hand-tightening handle 12 out of the groove 8, the extension handle 13, which is movably inserted on the opposite side of the hand-tightening handle 12, can be pulled outward through the lever 14 at its top. At this time, the extension handle 13 forms a longer lever arm, and the user can easily apply greater torque by simply turning the extension handle 13, thus achieving labor-saving operation. The extension handle 13 is covered with an elastic material, such as thermoplastic elastomer (TPE), silicone, or rubber, to provide a soft and comfortable grip. The elastic material itself has a high coefficient of friction, so that the extension handle 13 can be movably inserted into the hand-tightening handle 12, and can also prevent it from slipping between the hand-tightening handle 12 during hand-tightening, thus reducing stability.

[0029] Working principle: When the user needs to disassemble or install the handlebar 3, first use your fingers to hook the two handle grooves 11 on the outer surface of the sealing cover 10, and use the interference fit friction between it and the inner wall of the groove 8 to pull the sealing cover 10 vertically out of the opening end of the groove 8. This operation is simple and intuitive and does not require any auxiliary tools.

[0030] After the sealing cap 10 is removed, the head of the hand-tightening bolt 7 located inside the groove 8 is fully exposed. Direct hand-tightening mode: The user can directly grasp the two hand-tightening handles 12 fixed to the head of the hand-tightening bolt 7 and rotate clockwise to tighten the bolt, and counterclockwise to loosen it. Effort-saving extension mode: After manually turning the hand-tightening handle 12 out of the groove 8, the extension handle 13, which is movable through the opposite side of the hand-tightening handle 12, can be pulled outwards via the lever 14 at its top. At this time, the extension handle 13 forms a longer lever arm, allowing the user to easily apply greater torque simply by moving the extension handle 13, achieving effortless operation.

[0031] Installation: Align the positioning groove 5 at the bottom of the handlebar 3 with the top of the pole 2 and insert it vertically downwards. Since the top of the pole 2 has an irregular cross-section with "straight lines on the left and right and curved lines on the front and back", and the shape of the positioning groove 5 is perfectly matched, the two achieve precise circumferential positioning during the insertion process, ensuring that the handlebar 3 is in the correct direction. Then, pass the hand-tightening bolt 7 through the through hole 6 and screw it into the threaded hole 4 at the top of the pole 2 until it is completely locked.

[0032] Disassembly: Perform the above operations in reverse order. First, completely unscrew the hand-tightening bolt 7 by hand-tightening handle 12 or extension handle 13. Then, pull the handlebar 3 vertically upwards to complete disassembly.

[0033] After the operation is completed, when the hand-tightening handle 12 is rotated to a cross-shaped position with the handlebar 3, the extended end of the extension handle 13 will abut against the front side of the limiting groove 9 on the inner wall of the groove 8. When the extension handle 13 is manually extended, it goes deep into the limiting groove 9. The extension handle 13 just abuts against the groove wall of the limiting groove 9. Since the hand-tightening bolt 7 may loosen due to long-term use or bumpy road surface, the extension handle 13 going deep into the limiting groove 9 can provide a certain pre-tightening force for the hand-tightening bolt 7, forming a mechanical block to prevent the hand-tightening bolt 7 from loosening or even being completely unscrewed. Finally, the sealing cover 10 is reinserted into the groove 8 and firmly fixed by the friction generated by the interference fit of its elastic material (such as silicone or rubber), completely sealing and protecting the entire fastening mechanism.

[0034] In summary, this solution centrally arranges all operating components (hand-tightening bolt 7, hand-tightening handle 12, and extension handle 13) within the groove 8 at the top of the handlebar 3. Whether installing or disassembling, the user can operate while standing upright, with their line of sight naturally pointing downwards, clearly seeing the operating area without any bending or squatting. This "top-operation" method greatly enhances the ergonomic experience, making the operation process more comfortable and convenient. The integrated design of the hand-tightening bolt 7 and hand-tightening handle 12 allows users to complete basic tightening and loosening operations by hand. For applications requiring greater torque... In cases of torque, the built-in extension handle 13 provides an additional lever arm, further reducing the requirement for hand strength. The entire process requires no external tools, improving the ease of disassembling and assembling the handlebar 3. The removable elastic sealing cover 10 completely covers and seals the hand-tightening bolt 7 and its connection parts. The sealing cover 10 is made of elastic materials such as silicone and rubber, forming a tight interference fit with the groove 8. It can effectively block the intrusion of rainwater, moisture, dust, gravel and salt spray, preventing the oxidation and corrosion of metal parts and protecting them, thus facilitating disassembly and assembly.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
