Description

Technical Field

[0001] This utility model relates to the field of bicycle repair auxiliary equipment technology, and more specifically to an electric bicycle repair rack. Background Technology

[0002] With the popularization of cycling and the widespread use of various cycling devices such as shared bicycles and electric-assist bicycles, the demand for bicycle repair and maintenance has increased significantly. Traditional repair methods often use simple stands or manual lifting frames, requiring repair personnel to bend over or squat, which is not only physically demanding but also creates unstable working postures, easily leading to fatigue and safety hazards. For heavier cycling devices such as electric bicycles, manual lifting and securing are particularly difficult, compromising both repair efficiency and safety.

[0003] In existing technologies, some maintenance racks have incorporated electric lifting functions to replace manual lifting. However, existing electric maintenance racks still have the following shortcomings:

[0004] Firstly, most electric repair racks use a fixed column structure, which is bulky, heavy, and difficult to move and store. These structures are mostly arranged vertically with a single or double column. While they offer smooth lifting, disassembly is complex, they occupy a lot of space, and are difficult to meet the needs of repair shops, small workshops, or mobile service points.

[0005] Secondly, some products use a multi-section telescopic tube lifting structure, which can shorten the storage length to a certain extent. However, the telescopic joints have many gaps and the coaxiality is difficult to control. After long-term use, they are prone to shaking and wear, resulting in unstable lifting or reduced clamping accuracy.

[0006] Third, some existing devices have simple transmission mechanisms, often using screw lifting or direct chain drive, lacking tension adjustment structures. After a period of use, the transmission chain is prone to loosening, affecting lifting speed and stability, and may even cause jamming or chain skipping.

[0007] To address the aforementioned shortcomings, it is necessary to provide a compact, foldable, stable lifting, reliable clamping, and easy-to-operate electric bicycle repair rack to achieve comprehensive optimization in terms of portability, applicability, and stability. This repair rack should be able to achieve smooth lifting and secure locking while ensuring high load-bearing capacity, and should also be easy to fold and store quickly, making it suitable for various scenarios involving individual users, repair shops, and cycling teams. Utility Model Content

[0008] The purpose of this utility model is to provide a bicycle electric repair rack with a compact structure, stable lifting, reliable clamping and easy storage, so as to overcome the defects of existing repair racks, such as large size, complex structure, unstable transmission and inconvenient clamping.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] The electric bicycle repair rack includes an upper body, a lower body, a transmission mechanism, a clamping mechanism, an electronic control mechanism, a base, and a body reinforcement assembly.

[0011] The upper body and the lower body are connected by hinges; the upper body is provided with an upper guide rail and the lower body is provided with a lower guide rail, and the upper guide rail and the lower guide rail are connected by an outer V-shaped mating surface and an inner V-shaped mating surface.

[0012] The transmission mechanism includes a motor, a reducer, a first sprocket, a second sprocket, a transmission chain, and a guide rail slider assembly. The motor is connected to the first sprocket through the reducer. The transmission chain connects the first sprocket and the second sprocket. The transmission chain is connected to the guide rail slider assembly.

[0013] The clamping mechanism includes a double-jaw clamp and a clamping seat, with the clamping seat mounted on the guide rail slider assembly;

[0014] The electrical control mechanism includes an AC-DC power supply board, a control circuit board, an aviation socket, and wiring terminals;

[0015] The fuselage reinforcement assembly includes a back panel reinforcement assembly and a side panel reinforcement assembly. The back panel reinforcement assembly and the side panel reinforcement assembly can be replaced by an L-shaped reinforcement member, either together or separately. The L-shaped reinforcement member spans the connection area between the upper fuselage and the lower fuselage.

[0016] Preferably, a tension spring is connected to the transmission chain, with one end of the tension spring connected to the end of the chain and the other end fixed to the machine body.

[0017] Preferably, the transmission chain in the transmission mechanism can be replaced with a synchronous belt, and the first sprocket and the second sprocket can be replaced with a first synchronous pulley and a second synchronous pulley, respectively.

[0018] Preferably, the double-jaw clamp in the clamping mechanism is adjustable along the lateral side of the clamping seat.

[0019] Preferably, the electronic control mechanism is connected to a handheld controller or a foot controller via an aviation plug.

[0020] Preferably, the upper guide rail and the lower guide rail are connected by a connector.

[0021] Preferably, the back panel reinforcement assembly includes a straight connector and mounting holes, and the side panel reinforcement assembly includes fixing bolts; when an L-shaped reinforcement is used to replace the back panel reinforcement assembly and the side panel reinforcement assembly, the L-shaped reinforcement is connected to the upper fuselage and the lower fuselage by fixing bolts.

[0022] Preferably, the base is provided with a leveling screw.

[0023] Preferably, the hinge is provided with a limiting part.

[0024] Compared with existing technologies, the electric bicycle repair rack provided by this utility model features a foldable upper and lower body structure, allowing for flexible conversion between use and storage states. Its compact overall size facilitates transport and storage. The upper and lower guide rails utilize a mating structure with an outer V-shaped joint surface and an inner V-shaped joint surface, ensuring high sliding guidance precision and guaranteeing stability and smoothness during the lifting process.

[0025] The transmission mechanism employs a combination of a motor, reducer, sprocket, and chain (or timing belt) for reliable transmission and sensitive response, enabling smooth lifting and lowering for bicycle maintenance. By incorporating a tension spring structure on the transmission chain, appropriate tension is maintained during operation, preventing chain skipping and slippage, thereby improving service life and operational stability.

[0026] The fuselage reinforcement assembly consists of a back plate reinforcement assembly and a side plate reinforcement assembly, which together enhance the overall rigidity and load-bearing strength of the fuselage connection area. In different application scenarios, the back plate reinforcement assembly and the side plate reinforcement assembly can be replaced by L-shaped reinforcement components. The L-shaped reinforcement components have a simple structure and are easy to assemble. They can simultaneously reinforce the back and side structures of the fuselage, which helps to further improve the bending and torsional resistance of the entire machine.

[0027] The base is equipped with leveling screws, allowing for fine-tuning of the repair rack's level according to ground conditions, ensuring stable support for the equipment in various locations. The hinge structure features limiters to control the folding angle and prevent structural damage from excessive rotation during transport or operation.

[0028] In summary, the electric bicycle repair rack of this utility model has significantly improved upon existing technologies in terms of structural stability, ease of assembly, scope of application, and operational safety, and can meet the needs of bicycle repair, debugging, and display in various scenarios.

[0058] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0059] Example 1:

[0060] like Figures 1 to 15 As shown, this embodiment provides an electric bicycle repair rack, including an upper body 1, a lower body 2, a clamping mechanism 3, a base 4, a hinge 5, a transmission mechanism 6, an electronic control mechanism 7, and a body reinforcement assembly.

[0061] The upper body 1 and the lower body 2 are hinged together by a hinge 5, allowing the overall structure to switch between use and storage modes. The upper body 1 has an upper guide rail 101, and the lower body 2 has a lower guide rail 201. The two guide rails are mated together by an outer V-shaped mating surface 102 and an inner V-shaped mating surface 202 to form an integrated guide rail structure. The upper guide rail 101 and the lower guide rail 201 are fixed together by a connector 103, ensuring the positioning accuracy and sliding stability of the guide rails.

[0062] The transmission mechanism 6 is installed inside the machine body and is used to drive the clamping mechanism 3 to move up and down along the guide rail. The transmission mechanism 6 includes a motor 605, a reducer 606, a first sprocket 603, a second sprocket 604, a transmission chain 602, and a guide rail slider assembly 601. The motor 605 is connected to the first sprocket 603 through the reducer 606. The transmission chain 602 is installed between the first sprocket 603 and the second sprocket 604, and the transmission chain 602 is connected to the guide rail slider assembly 601. When the motor 605 drives the sprocket to rotate, the chain 602 drives the guide rail slider assembly 601 to move up and down along the guide rail, thereby realizing the lifting and lowering operation of the clamping mechanism 3. A tension spring 607 is connected to the transmission chain 602. One end of the tension spring 607 is connected to the end of the chain, and the other end is fixed to the machine body to maintain appropriate tension of the chain and prevent it from loosening or shifting during operation.

[0063] The clamping mechanism 3 consists of a market-standard double-jaw clamp 301 and a clamp base 302. The clamp base 302 is mounted on the guide rail slider assembly 601, and the double-jaw clamp 301 is connected to the clamp base 302 by mounting bolts. The double-jaw clamp 301 is a common and universal structure, including two opposing clamping arms. The distance between the clamping arms can be adjusted by a threaded adjusting rod to accommodate bicycle frames of different specifications and tube diameters. This universal clamping structure is widely available, easy to install, stable and reliable, and easy to replace and maintain. It can be directly used with the guide rail slider assembly 601 to achieve rapid clamping and release of the frame.

[0064] The electrical control mechanism 7 is installed inside the side wall of the upper fuselage 1 and includes an AC-DC power supply board 701, a control circuit board 702, an aviation socket 703, and a wiring terminal 704. The electrical control mechanism 7 is connected to the motor 605 via a cable and is externally connected to a handheld controller 801 or a foot pedal controller 801' via an aviation plug 8 to realize the start, stop, and steering control of the motor. The handheld controller 801 enables manual lifting operation, while the foot pedal controller 801' is suitable for the operation needs of maintenance personnel working with both hands.

[0065] The base 4 is located at the bottom of the lower body 2 and is used to support the entire repair frame structure. The base 4 is equipped with a leveling screw, which can be used to finely adjust the height according to the flatness of the ground to ensure that the equipment remains stable in different ground environments.

[0066] The fuselage reinforcement assembly is installed in the fuselage connection and stress-bearing areas to improve structural strength and rigidity. In this embodiment, the fuselage reinforcement assembly includes a back plate reinforcement assembly 9 and a side plate reinforcement assembly 10. The back plate reinforcement assembly 9 is bolted to the back joint of the upper fuselage 1 and the lower fuselage 2, and has a straight connector 901 and mounting holes 901' inside; the side plate reinforcement assembly 10 is installed on both sides of the fuselage side plate and connected by fixing bolts 1001 to enhance the bending strength of the fuselage folding connection parts.

[0067] Both the back panel reinforcement assembly 9 and the side panel reinforcement assembly 10 can be replaced by the L-shaped reinforcement 9' in terms of structural design. The L-shaped reinforcement 9' spans both the back panel and side panel areas of the fuselage. Its shape is a right-angle bend. It is connected to the upper fuselage 1 and the lower fuselage 2 by fixing bolts 1001, achieving the same reinforcement effect in the overall structure.

[0068] The hinge 5 is located between the upper body 1 and the lower body 2. The hinge 5 is equipped with a limiting part to limit the folding angle. By controlling the folding range through the limiting part, excessive rotation of the body can be prevented during handling or storage, thus maintaining the stability of the overall structure.

[0069] In this embodiment, the electric bicycle repair rack, when unfolded, achieves lifting and lowering operations via a motor driven by the transmission mechanism 6, allowing repair personnel to raise the bicycle to a suitable height for maintenance. In the stowed state, the upper body 1 folds downwards via hinge 5, fitting snugly against the lower body 2, reducing the overall size and facilitating transportation and storage. The entire device is compact, with stable transmission and reliable connections, enabling support and height adjustment for different types of bicycles, facilitating maintenance and debugging.

[0070] Example 2:

[0071] like Figure 16 As shown, this embodiment has the same basic structure as embodiment 1, the difference being that the transmission mechanism 6 adopts a synchronous belt structure.

[0072] The transmission mechanism 6 includes a motor 605, a reducer 606, a first synchronous pulley 603', a second synchronous pulley 604', a synchronous belt 602', and a guide rail slider assembly 601. The motor 605 is connected to the first synchronous pulley 603' via the reducer 606. A synchronous belt 602' is wound between the first synchronous pulley 603' and the second synchronous pulley 604', and the synchronous belt 602' is connected to the guide rail slider assembly 601. When the motor 605 operates, the first synchronous pulley 603' drives the synchronous belt 602' in a cyclical motion, thereby driving the guide rail slider assembly 601 to move up and down along the guide rail, realizing the lifting and lowering of the clamping mechanism 3.

[0073] The synchronous belt 602' consists of a rubber matrix and an internal reinforcing fiber layer, with a toothed structure on its surface that meshes with the tooth grooves of the synchronous pulley, making the transmission smoother. Compared with the chain drive in Example 1, this structure has lower operating noise, higher motion accuracy, and requires no lubrication or maintenance, making it suitable for clean environments in indoor maintenance workshops.

[0074] The guide rail section still consists of an upper guide rail 101 and a lower guide rail 201. The two guide rails are connected to each other through an outer V-shaped mating surface 102 and an inner V-shaped mating surface 202, and are fixed by a connector 103. The guide rail slider assembly 601 moves vertically on it.

[0075] The clamping mechanism 3 is the same as that in Embodiment 1, including a double-jaw clamp 301 and a clamp seat 302. The two clamping arms of the double-jaw clamp 301 are adjustable laterally along the clamp seat 302 to accommodate installations with different frame widths.

[0076] The fuselage reinforcement assembly still includes a back panel reinforcement assembly 9 and a side panel reinforcement assembly 10, which are installed on the back and side panels of the fuselage, respectively, during assembly. The back panel reinforcement assembly 9 is fixedly connected to the mounting hole 901' via a straight connector 901, and the side panel reinforcement assembly 10 is locked to the fuselage via fixing bolts 1001. In specific applications, both components can be replaced by an L-shaped reinforcement 9', which spans the area between the back panel and the side panels of the fuselage and is installed at the connection point between the upper fuselage 1 and the lower fuselage 2 via fixing bolts 1001, achieving integrated structural reinforcement.

[0077] The electrical control mechanism 7 is the same as in Embodiment 1, including an AC-DC power supply board 701, a control circuit board 702, an aviation socket 703, and a wiring terminal 704. The external control terminal is connected to a handheld controller 801 or a foot pedal controller 801' via an aviation plug 8 to realize lifting operation.

[0078] The base 4 is located at the bottom of the lower body 2, and is equipped with a leveling screw to adjust the stability of the repair rack on different surfaces. The hinge 5 still has a limiting part to ensure the range of folding angle.

[0079] This embodiment employs a synchronous belt drive, resulting in lower transmission noise and higher transmission accuracy for the repair rack. It also avoids the oil contamination issues associated with chain lubrication, making it suitable for repair or display environments where high cleanliness is required. The overall assembly structure is compatible with Embodiment 1, allowing for the selection of either chain or synchronous belt drive during manufacturing based on the intended use.

[0080] Example 3:

[0081] like Figure 17As shown, this embodiment improves the structural form of the fuselage reinforcement assembly based on Embodiments 1 and 2. This embodiment uses a single L-shaped reinforcement member 9' to replace both the backplate reinforcement assembly 9 and the sideplate reinforcement assembly 10, further simplifying the assembly structure and improving the overall rigidity of the fuselage.

[0082] The L-shaped reinforcing member 9' is an integrally bent structure, with its main body in a right-angle bend shape. One end extends along the back panel of the fuselage, and the other end extends along the side panel of the fuselage. The L-shaped reinforcing member 9' is installed across the connection between the upper fuselage 1 and the lower fuselage 2. Its back portion contacts and fits with the back panel surface of the upper fuselage 1 and the lower fuselage 2, while its side portion fits against the side panels of the fuselage. The L-shaped reinforcing member 9' is connected to the upper fuselage 1 and the lower fuselage 2 by fixing bolts 1001, ensuring the stability of the fuselage in both folded and unfolded states.

[0083] The L-shaped reinforcing member 9' has multiple mounting holes 901', which are used for bolt positioning and tightening, ensuring a reliable connection between the reinforcing member and the fuselage. This structure reinforces the back and sides of the fuselage simultaneously with a single component, reducing the number of parts, simplifying the installation process, and enhancing the bending and torsional resistance of the connection.

[0084] The structures of the transmission mechanism 6, electrical control mechanism 7, clamping mechanism 3, base 4, and hinge 5 are the same as in Embodiment 1. The transmission mechanism 6 can be selected from either chain drive or synchronous belt drive as needed, with the chain drive option corresponding to... Figures 3-4 Structure, corresponding synchronous belt scheme Figure 16 structure.

[0085] During assembly, the L-shaped reinforcing member 9' is connected to the upper fuselage 1 and the lower fuselage 2 respectively by fixing bolts 1001, and its installation position covers the adjacent area of ​​the fuselage folding hinge 5. Since the reinforcing member is distributed on both the back plate and the side plate, a closed support structure is formed at the folding joint, thereby improving the structural strength and stability of the entire repair frame during load-bearing and lifting processes.

[0086] The L-shaped reinforcing member 9' can be made by bending steel plate or extruding aluminum alloy, and the surface is treated with spraying or anodizing to improve corrosion resistance and extend service life. Depending on different requirements, the thickness of the L-shaped reinforcing member 9' can be selected between 2mm and 5mm to balance weight and rigidity.

[0087] The structure of this embodiment makes the repair rack less prone to loosening or deformation at the joints during long-term use, thus improving the overall reliability and durability of the equipment. The L-shaped reinforcing member 9' forms an integrated support frame with the machine body, which is simple in structure, easy to disassemble and maintain, and can be adjusted in size according to different machine body structures, thus having good versatility.

[0088] In summary, this embodiment replaces the back plate reinforcement assembly 9 and the side plate reinforcement assembly 10 with an L-shaped reinforcement member 9' to form a more compact integrated reinforcement structure. While maintaining the folding function, it improves the structural strength and assembly efficiency, making it suitable for mass production and multi-scenario applications.

[0089] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
