Description

Technical Field

[0001] This application relates to the field of electric vehicle technology, and more particularly to a basket fixing bracket assembly and an electric vehicle. Background Technology

[0002] Driven by the demand for modern urban commuting and short-distance travel, the appearance design and structural functions of two-wheeled electric bicycles and electric motorcycles are becoming increasingly diversified.

[0003] Two-wheeled electric bicycles, electric motorcycles and other vehicles are equipped with baskets to improve the convenience of carrying goods.

[0004] However, the existing connection structure between the frame tube and the basket support has low stability. When bumping or turning, uneven displacement of the connection points on both sides is likely to occur, causing the basket to shake, make abnormal noises, or even loosen the bolts, which poses a safety hazard. Utility Model Content

[0005] In view of the above problems, this application provides a basket fixing bracket assembly and an electric vehicle to solve the problem that the existing connection structure between the frame tube and the basket bracket has low stability. When bumping or turning, uneven displacement of the connection points on both sides is easy to occur, which leads to basket shaking, abnormal noise, and even loosening of bolts, posing a safety hazard.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0007] A first aspect of this application provides a bicycle basket fixing bracket assembly, comprising:

[0008] Basket support;

[0009] The frame tube has a first connecting part at both ends along its extension direction. The first connecting part is located at the end of the frame tube near the basket support.

[0010] The U-shaped bracket connects the basket bracket and the frame tube. Along the extension direction of the U-shaped bracket, the two ends of the U-shaped bracket are provided with second connecting parts, which are fixed to the first connecting parts. The U-shaped bracket is also provided with a fixing part, which is used to fix the basket bracket.

[0011] In one possible implementation, the first connecting part is provided with at least two first through holes; the second connecting part is provided with at least two first threaded holes, and the first threaded holes and the first through holes are arranged opposite to each other along the wall thickness direction of the first connecting part.

[0012] The basket mounting bracket assembly also includes a first fastener, which passes through a first through hole and engages with a first threaded hole. The first fastener is used to fix the first connecting part and the second connecting part.

[0013] In one possible implementation, the U-shaped bracket includes a bracket body and a shell; the bracket body, the fixing part, and the second connecting part are integrally formed; the shell covers the bracket body, and the shell covers the first connecting part and the second connecting part.

[0014] In one possible implementation, the support body includes a first connecting segment and a second connecting segment connected to both ends of the first connecting segment, the two second connecting segments being arranged at an angle; a second connecting portion is provided at the end of the second connecting segment away from the first connecting segment;

[0015] Fixing parts are provided on the first connecting section and the two second connecting sections.

[0016] In one possible implementation, the outer casing includes a first casing and a second casing, which are disposed opposite to each other along the wall thickness direction of the support body in a cross section perpendicular to the extension direction of the support body.

[0017] The first housing includes a first housing segment and a second housing segment connected to both ends of the first housing segment;

[0018] The basket mounting bracket assembly also includes a second fastener for securing the first shell section to the first connecting section and the second shell section to the second connecting section.

[0019] The second shell is welded to the first shell.

[0020] In one possible implementation, a first clearance hole is provided on the outer casing for clearance of the fixing part; and the fixing part extends at least partially to the side of the outer casing away from the bracket body, and the fixing part abuts against the bottom wall of the basket bracket.

[0021] In one possible implementation, a second clearance hole is provided on the housing, which is used to avoid the first fastener.

[0022] In one possible implementation, a second threaded hole is provided on the fixing part; a second through hole is provided on the basket bracket;

[0023] The basket mounting bracket assembly also includes a third fastener, which passes through the second through hole and engages with the second threaded hole. The third fastener is used to fix the basket bracket to the mounting part.

[0024] In one possible implementation, at least one side of the first connecting portion is provided with a first reinforcing rib along the wall width direction of the first connecting portion;

[0025] And / or, along the wall width direction of the second connection portion, at least one side of the second connection portion is provided with a second reinforcing rib.

[0026] A second aspect of this application provides an electric vehicle, including the basket fixing bracket assembly as described above.

[0027] The basket mounting bracket assembly provided in this application integrates two originally independent connection points into a rigid, integral frame by setting a U-shaped bracket between the basket bracket and the frame tube. The U-shaped bracket itself is a single load-bearing component, and its two ends, after being fixed to the first connection point of the frame tube, effectively resist forces (mainly torque) that cause relative displacement between the two connection points. Whether experiencing longitudinal bumps or lateral turns, the U-shaped bracket ensures that the force is absorbed and redistributed within its own structure before acting on the basket bracket, thus preventing the two legs of the frame tube from being pried apart or misaligned, improving connection stability, and effectively eliminating shaking and abnormal noise. Under load, the complex loads from the basket (such as downward gravity and impact forces in the forward direction) first act on the basket bracket, and then are transmitted to the entire body of the U-shaped bracket through the fixing parts on the U-shaped bracket. Since both ends of the U-shaped bracket are fixed to the frame tube, the force is effectively distributed to the two legs of the frame tube, rather than being concentrated at a single point. This reduces the load on individual connection points, effectively decreasing the likelihood of bolt loosening and thus improving the safety and durability of the entire structure.

[0028] In addition to the technical problems solved by the embodiments of this application, the technical features constituting the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions described above, other technical problems that the basket fixing bracket assembly and electric vehicle provided by the embodiments of this application can solve, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further explained in detail in the specific implementation.

[0046] First, those skilled in the art should understand that these embodiments are merely for explaining the technical principles of this application and are not intended to limit the scope of protection of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0047] Secondly, it should be noted that, in the description of the embodiments of this application, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0048] As described in the background section, the existing connection structure between the frame tube and the basket support in the related technology has low stability. When bumping or turning, uneven displacement of the connection points on both sides is likely to occur, causing the basket to shake, make abnormal noises, or even loosen the bolts, which poses a safety hazard.

[0049] To address the aforementioned technical problems, this application provides a basket fixing bracket assembly and an electric vehicle. The basket fixing bracket assembly includes: a basket bracket; a frame tube, with first connecting portions at both ends of the frame tube along its extension direction, the first connecting portions being located at the ends of the frame tube near the basket bracket; a U-shaped bracket connecting the basket bracket and the frame tube; second connecting portions at both ends of the U-shaped bracket along its extension direction, the second connecting portions being fixed to the first connecting portions; and a fixing portion on the U-shaped bracket for fixing the basket bracket.

[0050] The basket mounting bracket assembly provided in this application integrates two originally independent connection points into a rigid, integral frame by setting a U-shaped bracket between the basket bracket and the frame tube. The U-shaped bracket itself is a single load-bearing component, and its two ends, after being fixed to the first connection point of the frame tube, effectively resist forces (mainly torque) that cause relative displacement between the two connection points. Whether experiencing longitudinal bumps or lateral turns, the U-shaped bracket ensures that the force is absorbed and redistributed within its own structure before acting on the basket bracket, thus preventing the two legs of the frame tube from being pried apart or misaligned, improving connection stability, and effectively eliminating shaking and abnormal noise. Under load, the complex loads from the basket (such as downward gravity and impact forces in the forward direction) first act on the basket bracket, and then are transmitted to the entire body of the U-shaped bracket through the fixing parts on the U-shaped bracket. Since both ends of the U-shaped bracket are fixed to the frame tube, the force is effectively distributed to the two legs of the frame tube, rather than being concentrated at a single point. This reduces the load on individual connection points, effectively decreasing the likelihood of bolt loosening and thus improving the safety and durability of the entire structure.

[0051] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0052] Please refer to the attached document. Figure 1-11 The first aspect of this application provides a bicycle basket fixing bracket assembly, comprising:

[0053] 10 basket support;

[0054] The frame tube 20 has a first connecting part 201 at both ends along its extension direction. The first connecting part 201 is located at the end of the frame tube 20 near the basket support 10.

[0055] The U-shaped bracket 30 is connected between the basket bracket 10 and the frame tube 20. Along the extension direction of the U-shaped bracket 30, the two ends of the U-shaped bracket 30 are provided with second connecting parts 3101, which are fixed to the first connecting parts 201. The U-shaped bracket 30 is also provided with a fixing part 3103, which is used to fix the basket bracket 10.

[0056] The basket mounting bracket assembly provided in this application integrates two originally independent connection points into a rigid integral frame by setting a U-shaped bracket 30 between the basket bracket 10 and the frame tube 20. The U-shaped bracket 30 itself is an integral load-bearing component, and its two ends of the second connecting part 3101 are fixed to the first connecting part 201 of the frame tube 20, thereby effectively resisting the forces (mainly torque) that cause relative displacement between the two connection points. Whether it is longitudinal bumps or lateral turns, the U-shaped bracket 30 can ensure that the force is absorbed and redistributed within its own structure before acting on the basket bracket 10, thereby preventing the two legs of the frame tube 20 from being pried apart or misaligned, improving the connection stability, and effectively eliminating shaking and abnormal noise. When under force, the complex load from the basket (such as downward gravity and forward impact force) first acts on the basket bracket 10, and then is transmitted to the entire body of the U-shaped bracket 30 through the fixing part 3103 on the U-shaped bracket 30. Since both ends of the U-shaped bracket 30 are fixed to the frame tube 20, the force is effectively distributed to the two legs of the frame tube 20, rather than being concentrated at a single point. This reduces the load on individual connection points, effectively decreasing the possibility of bolt loosening and thus improving the safety and durability of the entire structure.

[0057] Furthermore, the U-shaped bracket 30, as a single component, provides all the necessary connection points in one go (the second connecting part 3101 is used to connect the frame tube 20, and the fixing part 3103 is used to connect the basket bracket 10). During installation, simply align the U-shaped bracket 30 with the frame tube 20, fix the second connecting part 3101 to the first connecting part 201, and then fix the basket bracket 10 to the fixing part 3103. This simplifies the operation steps and ensures the accurate positioning of the basket bracket 10's installation reference, avoiding uneven stress caused by installation errors.

[0058] Furthermore, the basket support 10 can be made of metal.

[0059] Furthermore, the frame tube 20 can be made of metal.

[0060] In one possible implementation, please see Figure 6 As shown, the first connecting portion 201 has at least two first through holes 202; please refer to Figure 9 As shown, at least two first threaded holes 3102 are provided on the second connecting part 3101, and the first threaded holes 3102 are arranged opposite to the first through holes 202 along the wall thickness direction of the first connecting part 201.

[0061] Please see Figure 4As shown, the basket fixing bracket assembly also includes a first fastener 41, which passes through the first through hole 202 and is threaded into the first threaded hole 3102. The first fastener 41 is used to fix the first connecting part 201 and the second connecting part 3101.

[0062] In this embodiment, the first connecting portion 201 has at least two first through holes 202, and the second connecting portion 3101 has at least two first threaded holes 3102 corresponding to the first through holes 202. This forms at least two spaced-apart fastening points on the first connecting portion 201 and the second connecting portion 3101, effectively resisting the torque from the basket and preventing slight rotation of the U-shaped bracket 30 relative to the frame tube 20, ensuring the safety and durability of the connection. At least two first fasteners 41 fix the first connecting portion 201 and the second connecting portion 3101, ensuring a uniform and tight fit across the entire connection contact surface, effectively enhancing the rigidity of the connection. This makes the U-shaped bracket 30 and the frame tube 20 form an integral load-bearing structure, effectively suppressing displacement and deformation in various directions, further ensuring the stability of the basket and eliminating abnormal noise.

[0063] Furthermore, the first fastener 41 can be an anti-loosening screw, which can effectively resist the continuous, high-frequency micro-vibrations during vehicle operation, ensure that the connection point always remains tight, effectively avoid the possibility of loosening, and improve safety.

[0064] Further, please see Figure 6 As shown, one of the first through holes 202 can be a strip-shaped hole, thus providing adjustment allowance and compensating for manufacturing and assembly tolerances. During assembly, the first fastener 41 can be passed through the standard round hole and slightly tightened, at which point the approximate positions of the first connecting part 201 and the second connecting part 3101 are fixed. Then, the other first fastener 41 can be easily inserted at any position within the length of the strip-shaped hole. This compensates for manufacturing and assembly tolerances, improving the convenience and error tolerance of assembly.

[0065] In one possible implementation, please see Figure 7 , Figure 8 and Figure 9 As shown, the U-shaped bracket 30 includes a bracket body 31 and a shell 32; the bracket body 31, the fixing part 3103, and the second connecting part 3101 are integrally formed; the shell 32 covers the bracket body 31, and the shell 32 covers the first connecting part 201 and the second connecting part 3101.

[0066] In this embodiment, the bracket body 31 undertakes core mechanical functions, ensuring the entire U-shaped bracket 30 has high mechanical strength, rigidity, and durability. The bracket body 31, the fixing part 3103, and the second connecting part 3101 are integrally formed, further ensuring the continuity of force and overall stability. The outer shell 32 covers the bracket body 31, effectively isolating it from moisture and corrosive substances, protecting the internal bracket body 31 from rusting, and preventing users from directly contacting the edges and corners of the bracket body 31, providing a more user-friendly feel and preventing scratches, while also improving aesthetics. The outer shell 32 covers the first connecting part 201 and the second connecting part 3101, effectively preventing water and mud from directly impacting and corroding the first fastener 41 and the first threaded hole 3102, effectively slowing down the corrosion rate of the first fastener 41, and ensuring that it can still be easily disassembled after long-term use.

[0067] Furthermore, the support body 31 can be made of high-strength metal materials, such as high-strength steel, aluminum alloy, etc.

[0068] Furthermore, the outer casing 32 may be made of engineering plastics, nylon, or decorative alloys.

[0069] In one possible implementation, please see Figure 9 As shown, the bracket body 31 includes a first connecting section 311 and a second connecting section 312 connected to both ends of the first connecting section 311. The two second connecting sections 312 are arranged at an angle. A second connecting part 3101 is provided at the end of the second connecting section 312 away from the first connecting section 311.

[0070] A fixing part 3103 is provided on the first connecting section 311 and the two second connecting sections 312.

[0071] In this embodiment, by providing fixing parts 3103 on both the first connecting section 311 and the two second connecting sections 312, the basket support 10 is securely fastened at at least three different positions. These three points form a stable support plane, making the combination of the basket support 10 and the U-shaped support 30 more rigid, able to resist torsional loads from multiple directions, effectively preventing the basket support 10 from swaying relative to the U-shaped support 30, and achieving a stable and reliable rigid connection. Moreover, the two angled second connecting sections 312 and the first connecting section 311 together form an approximately triangular or trapezoidal rigid frame; arranging the fixing parts 3103 on the three sides of this rigid frame enhances the overall rigidity of the basket support 10 mounting base. This makes the entire mounting structure less deformable when facing complex loads, and the structure more stable.

[0072] In one possible implementation, please see Figure 8 and Figure 11As shown, the outer shell 32 includes a first shell 321 and a second shell 322. On a cross section perpendicular to the extending direction of the support body 31, the first shell 321 and the second shell 322 are arranged opposite to each other along the wall thickness direction of the support body 31.

[0073] The first housing 321 includes a first housing segment 3211 and a second housing segment 3212 connected to both ends of the first housing segment 3211;

[0074] The basket mounting bracket assembly also includes a second fastener 42, which is used to fix the first shell section 3211 to the first connecting section 311 and the second shell section 3212 to the second connecting section 312.

[0075] The second housing 322 is welded to the first housing 321.

[0076] In this embodiment, the first shell segment 3211 and the first connecting segment 311, and the second shell segment 3212 and the second connecting segment 312 are fixedly connected by the second fastener 42, thereby rigidly connecting the bracket body 31 and the first shell 321 together. This eliminates the possibility of relative movement between the bracket body 31 and the first shell 321, thus preventing abnormal noise. By welding the second shell 322 to the first shell 321, the joint between the first shell 321 and the second shell 322 is completely fused and sealed, making the outer shell 32 a sealed protective sleeve. This effectively prevents moisture, dust, and corrosive substances from penetrating the interior of the U-shaped bracket 30, which helps to extend the service life of the entire assembly.

[0077] During assembly, the bracket body 31 is first positioned with the first housing 321 (the first housing segment 3211 corresponds to the first connecting segment 311, and the second housing segment 3212 corresponds to the second connecting segment 312). Then, the second fastener 42 is used to fix the bracket body 31 and the first housing 321 together. Finally, the second housing 322 is fastened to the first housing 321 and welded to it. This optimized assembly process enables convenient assembly from the inside out, simplifies the assembly flow, avoids the difficulty of aligning and encapsulating the complex bracket body 31 into a single housing, and improves production efficiency and yield.

[0078] Furthermore, the second housing 322 and the first housing 321 can be ultrasonically welded.

[0079] In one possible implementation, please see Figure 7 and Figure 10 As shown, a first clearance hole 3201 is provided on the outer shell 32, which is used to avoid the fixing part 3103; and the fixing part 3103 extends at least partially to the side of the outer shell 32 away from the bracket body 31, and the fixing part 3103 abuts against the bottom wall of the basket bracket 10.

[0080] In this embodiment, the support body 31 is the main mechanical load-bearing component, and the fixing part 3103 is a part of the support body 31. By opening a first clearance hole 3201 on the outer shell 32, the bottom wall of the basket support 10 directly contacts and is fastened to the fixing part 3103. In this way, the force from the basket is transmitted to the high-strength support body 31 through the shortest and most direct path from the basket support 10 to the fixing part 3103, and finally distributed to the frame tube 20. The outer shell 32 is completely unaffected by the core load. This not only ensures that the entire structure has higher rigidity and strength, but also avoids the slight friction and impact noise that may be generated between the basket support 10 and the outer shell 32 due to long-term vibration, thus avoiding abnormal noise.

[0081] In one possible implementation, please see Figure 2 , Figure 7 and Figure 10 As shown, a second clearance hole 3202 is provided on the outer casing 32, which is used to avoid the first fastener 41.

[0082] In this embodiment, the first fastener 41 needs to pass through the first through hole 202 on the frame tube 20 and be screwed into the first threaded hole 3102 on the bracket body 31 to complete the mechanical connection. The second clearance hole 3202 provides a physical channel for the passage of the first fastener 41 and the operation of tools. This ensures that the rigid connection function of the bracket body 31 and the connection between the bracket body 31 and the frame tube 20 is not affected when fully enclosed by the outer shell 32. Moreover, the second clearance hole 3202 facilitates the disassembly of the first fastener 41. When maintenance is required, the first fastener 41 can be loosened and removed using tools through the second clearance hole 3202, thereby facilitating the removal of the U-shaped bracket 30 from the frame tube 20.

[0083] In one possible implementation, please see Figure 4 and Figure 9 As shown, a second threaded hole 3104 is provided on the fixing part 3103; please refer to Figure 5 As shown, a second through hole 101 is provided on the basket support 10;

[0084] Please see Figure 2 As shown, the basket mounting bracket assembly also includes a third fastener 43, which passes through the second through hole 101 and is threaded into the second threaded hole 3104. The third fastener 43 is used to fix the basket bracket 10 to the fixing part 3103.

[0085] In this embodiment, by passing the third fastener 43 through the second through hole 101 of the basket bracket 10 and directly screwing it into the second threaded hole 3104 on the bracket body 31, a rigid connection can be formed between the basket bracket 10 and the bracket body 31. This connection can withstand enormous tensile and shear forces, tightly locking the basket bracket 10, the U-shaped bracket 30, and the frame tube 20 into a single unit. It effectively resists the upward impact force generated by the basket during bumpy rides, as well as the torsional load generated during turning or under load, ensuring the stability of the connection.

[0086] Moreover, the force transmission path is very direct and efficient: basket → basket support 10 → third fastener 43 → support body 31 → frame tube 20. This path is entirely supported by high-strength components, ensuring smooth force flow without elastic deformation in intermediate links. This allows the load from the basket to be effectively distributed to the frame tube 20 through the two legs of the support body 31, avoiding stress concentration and improving the fatigue life of the entire structure.

[0087] In one possible implementation, please see Figure 4 As shown, along the wall width direction of the first connecting portion 201, at least one side of the first connecting portion 201 is provided with a first reinforcing rib 203;

[0088] And / or, along the wall width direction of the second connecting portion 3101, at least one side of the second connecting portion 3101 is provided with a second reinforcing rib 3105.

[0089] In this embodiment of the application, by providing a first reinforcing rib 203 on the first connecting part 201 and a second reinforcing rib 3105 on the second connecting part 3101, it is possible not only to effectively resist deformation force and ensure that the pre-tightening force of the first fastener 41 remains stable, thereby avoiding the possibility of loosening, but also to reduce the weight of the entire assembly while ensuring or even improving the connection strength and rigidity between the first connecting part 201 and the second connecting part 3101.

[0090] A second aspect of this application also provides an electric vehicle, including the basket fixing bracket assembly as described above.
