Description

Technical Field

[0001] This utility model relates to the field of bicycle storage technology, and more specifically, to a bicycle rack. Background Technology

[0002] In long-distance travel or outdoor activities, bicycles often need to be carried to the destination for further riding. Therefore, the demand for mounting bicycles on the outside of vehicles is increasing. In this case, bicycle racks play a crucial role, needing not only to ensure the bicycle's safety and stability during transport but also to consider user convenience and the overall aesthetics of the vehicle. Traditional bicycle racks primarily mount bicycles on the roof or rear. While roof racks are widely used, they are more difficult to operate when loading and unloading, easily causing physical strain on the user. Furthermore, the increased height may affect the bicycle's ability to navigate low obstacles, and at high speeds, it increases wind resistance, affecting the bicycle's range. In contrast, rear bicycle racks are generally accepted due to their ease of installation and removal and minimal impact on vehicle performance.

[0003] When not carrying the bicycle, to reduce the space occupied by the rack and minimize the safety hazards posed by the rack protruding from the bicycle body to surrounding vehicles and pedestrians, a folding structure is often used to fold and store the rack, thus reducing its size. Existing racks typically use a combination of pneumatic rods, hydraulic rods, or connecting blocks and plates to ensure that the rack can be folded and unfolded. However, existing rack folding structures are bulky and complex, still occupying a significant amount of space even when folded. Utility Model Content

[0004] The main purpose of this utility model is to provide a bicycle rack that can solve the problem of the large size of the existing bicycle rack folding structure, reduce the space occupied by the folding structure, and has a simple structure and low cost.

[0005] To achieve the above objectives, according to one aspect of the present invention, a bicycle hanger is provided, including a first connecting frame, a second connecting frame, and a support frame. A first end of the second connecting frame is connected to a second end of the first connecting frame, and the second end of the second connecting frame is adapted to connect to a trailer structure at the rear of a vehicle. A sliding member is provided at the first end of the first connecting frame, and a connecting member is provided at the first end of the support frame. The sliding member has a locked position and an unlocked position. The sliding member and the connecting member are slidably connected and can switch between the locked position and the unlocked position. When the sliding member is in the unlocked position, the support frame can switch between a folded state and an unfolded state.

[0006] Furthermore, the connector is provided with a limiting groove, which has a locked position and an unlocked position. The slider passes through the limiting groove and can switch between the locked position and the unlocked position.

[0007] Furthermore, the limiting groove includes a first limiting section, a second limiting section, and a third limiting section. The second limiting section is located at the first end of the first limiting section, and the third limiting section is located at the second end of the first limiting section. When the slider is located in the first limiting section, the slider is in the unlocked position. When the slider enters the second limiting section, the slider is in the first locked position, and the support frame is in the unfolded state. When the slider enters the third limiting section, the slider is in the second locked position, and the support frame is in the folded state.

[0008] Furthermore, a lifting component is provided at the first end of the first connecting frame, and an elastic element is provided at the first end of the first connecting frame. The elastic element is used to drive the lifting component to move relative to the first connecting frame. The lifting component is connected to the sliding element, and the lifting component can drive the sliding element to switch between the locked position and the unlocked position.

[0009] Furthermore, the lifting assembly includes a fixing part, the first end of the first connecting frame is a hollow structure, the fixing part is movably disposed in the first connecting frame, the fixing part is provided with a mounting hole, and the sliding member is fixedly disposed in the mounting hole; the side of the hollow structure is provided with a first sliding groove, and the sliding member passes through the first sliding groove.

[0010] Furthermore, a mounting base is fixedly installed inside the first connecting frame, the fixing part is slidably installed inside the mounting base, the mounting base is provided with a second slide groove corresponding to the first slide groove, and the sliding member passes through the first slide groove and the second slide groove.

[0011] Furthermore, an elastic element is provided at the bottom of the fixing part, one end of which abuts against the fixing part and the other end of which abuts against the mounting base. A pressing part is also provided at the top of the fixing part, with the top of the pressing part being higher than the mounting base.

[0012] Furthermore, a mounting base is fixedly installed inside the first connecting frame, and a locking component is rotatably installed on the mounting base, which can engage with the lifting assembly.

[0013] Applying the technical solution of this utility model, the first connecting frame is one of the main support structures of the bicycle hanger, used to connect the rear of the car and the support frame, ensuring that the hanger can be firmly fixed to the car. Simultaneously, the first connecting frame provides support for the support frame. The second connecting frame connects the first connecting frame to the trailer structure at the rear of the vehicle, ensuring the hanger is firmly attached to the vehicle. A sliding member is provided at the first end of the first connecting frame, and a connecting member is provided at the first end of the support frame. The sliding member and the connecting member are slidably connected, allowing the support frame to switch between a folded and unfolded state through this sliding engagement. Simultaneously, the support frame is limited and fixed in either the folded or unfolded state, ensuring it does not loosen. The support frame carries the bicycle; when folded, its volume is reduced, minimizing space occupation and making it more suitable for storage; when unfolded, it provides sufficient space to carry the bicycle, ensuring its fixation and safety.

[0014] The bicycle rack provided by this utility model allows the support frame to switch between a folded state and an unfolded state by setting a sliding member and a connecting member. Compared with the existing folding structure of pneumatic rods, hydraulic rods or connecting blocks and connecting plates, it significantly reduces the volume of the folding structure, thereby solving the problem of the large volume of the existing bicycle rack folding structure, reducing the space occupied by the folding structure, and using the sliding member and connecting member to achieve unlocking and locking. The structure is simple and low cost. Attached Figure Description

[0040] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0041] See also Figures 1 to 22 As shown, this utility model provides a bicycle rack, which includes a first connecting frame 1, a second connecting frame 5, and a support frame 4. The first end of the second connecting frame 5 is connected to the second end of the first connecting frame 1, and the second end of the second connecting frame 5 is adapted to be connected to the trailer structure at the rear of the vehicle. The first end of the first connecting frame 1 is provided with a sliding member 11, and the first end of the support frame 4 is provided with a connecting member 2. The sliding member 11 has a locked position and an unlocked position. The sliding member 11 is slidably connected to the connecting member 2 and can switch between the locked position and the unlocked position. When the sliding member 11 is in the unlocked position, the support frame 4 can switch between a folded state and an unfolded state.

[0042] In the above technical solution, the first connecting frame 1 is one of the main supporting structures of the bicycle rack, used to connect the rear of the car and the support frame, ensuring that the rack can be firmly fixed to the car. Simultaneously, the first connecting frame 1 provides support for the support frame 4. The second connecting frame 5 connects the first connecting frame 1 to the trailer structure at the rear of the vehicle, ensuring the rack is firmly attached to the vehicle. A sliding member 11 is provided at the first end of the first connecting frame 1, and a connecting member 2 is provided at the first end of the support frame 4. The sliding member 11 and the connecting member 2 are slidably connected. Through the sliding cooperation between the sliding member 11 and the connecting member 2, the support frame 4 can switch between a folded state and an unfolded state, while simultaneously limiting and fixing the support frame in either the folded or unfolded state, ensuring that the support frame 4 does not loosen. The support frame 4 is used to carry the bicycle. When folded, the support frame 4 is smaller in size, reducing space occupation and making it more suitable for storage; when unfolded, it provides sufficient space to carry the bicycle, ensuring its fixation and safety.

[0043] The bicycle rack provided by this utility model allows the support frame 4 to switch between a folded state and an unfolded state by setting a sliding member 11 and a connecting member 2. Compared with the folding structure of the prior art that uses a combination of pneumatic rods, hydraulic rods or connecting blocks and connecting plates, the volume of the folding structure is significantly reduced, thus solving the problem of the large volume of the existing bicycle rack folding structure and reducing the space occupied by the folding structure. In addition, the unlocking and locking are achieved by using the sliding member and the connecting member in combination, which is simple in structure and low in cost.

[0044] In one embodiment of the present invention, the connector 2 is provided with a limiting groove 21, the limiting groove 21 having a locked position and an unlocked position, and the sliding member 11 passing through the limiting groove 21 and being able to switch between the locked position and the unlocked position.

[0045] In the above technical solution, the connector 2 serves as the connecting hub between the support frame 4 and the first connecting frame 1. The limiting groove 21 provided on the connector 2 provides a sliding path for the slider 11 and limits the sliding of the slider 11. The slider 11 is installed in the limiting groove 21 and can slide along the limiting groove 21. By changing the position of the slider 11 in the limiting groove 21, the support frame 4 can be locked and unlocked, simplifying the structure and method of locking and unlocking.

[0046] In one embodiment of this utility model, the limiting groove 21 includes a first limiting segment 211, a second limiting segment 212, and a third limiting segment 213. The second limiting segment 212 is disposed at the first end of the first limiting segment 211, and the third limiting segment 213 is disposed at the second end of the first limiting segment 211. When the slider 11 is located in the first limiting segment 211, the slider 11 is in the unlocked position. When the slider 11 enters the second limiting segment 212, the slider 11 is in the first locked position, and the support frame 4 is in the unfolded state. When the slider 11 enters the third limiting segment 213, the slider 11 is in the second locked position, and the support frame 4 is in the folded state. Specifically, the first limiting segment 211 is an arc-shaped hole, and the second limiting segment 212 and the third limiting segment 213 are both turned at a certain angle relative to the first limiting segment 211.

[0047] In the above technical solution, the limiting groove 21 is subdivided into three different sections, each corresponding to a specific state of the support frame 4. By adjusting the position of the slider 11 within the limiting groove, the position and state of the support frame 4 can be easily adjusted. When the slider 11 is in the first limiting section 211, it is in the unlocked position, allowing the user to fold or unfold the support frame 4. When the slider 11 enters the second limiting section 212, it is in the first locked position, where the support frame 4 is unfolded and firmly locked, effectively preventing accidental folding during cycling and ensuring the stability and safety of the support frame 4 and the bicycle on it. When the slider 11 enters the third limiting section 213, it is in the second locked position, where the support frame 4 is folded to its most compact state and firmly locked, reducing the space occupied by the support frame 4 and preventing accidental unfolding after storage.

[0048] Compared to existing folding structures that use pneumatic rods, hydraulic rods, or combinations of connecting blocks and connecting plates, this utility model, by setting a first limiting segment 211, a second limiting segment 212, and a third limiting segment 213, allows users to easily control the folding and unfolding of the support frame 4 simply by adjusting the position of the sliding member 11 within the limiting groove 21, thus reducing the difficulty of adjusting the support frame 4.

[0049] In one embodiment of the present invention, a lifting component 12 is further provided at the first end of the first connecting frame 1. An elastic element 17 is provided at the first end of the first connecting frame 1. The elastic element 17 is used to drive the lifting component 12 to move relative to the first connecting frame 1. The lifting component 12 is connected to the sliding element 11. The lifting component 12 can drive the sliding element 11 to switch between the locked position and the unlocked position.

[0050] In the above technical solution, the lifting assembly 12 can move up and down relative to the first connecting frame 1, thereby effectively driving the sliding member 11 to switch between the locked and unlocked positions. Users only need to control the lifting position of the lifting assembly 12 to easily switch the rack between the unfolded and folded states, significantly improving the convenience of state switching for the support frame 4. The elastic member 17 provides power for the reset action of the lifting assembly 12. When the user operates the lifting assembly 12 to adjust the support frame 4 to the target state, and the sliding member 11 needs to move from the unlocked position to the locked position to lock the adjusted state, the elastic member 17 releases elastic potential energy to drive the sliding member 11 into the locked position, thus locking the current state of the support frame 4. Simultaneously, the elastic member 17 can also provide additional locking force after the sliding member 11 reaches the predetermined position, ensuring the stability of the sliding member 11 in the locked position, thereby ensuring the safe fixation of the support frame 4 and the bicycle it carries. The combination of the lifting assembly 12 and the elastic member 17 makes the folding and unfolding operation of the support frame 4 easy and quick, significantly reducing the difficulty of operation.

[0051] In one embodiment of the present invention, the lifting assembly 12 includes a fixing part 121, the first end of the first connecting frame 1 is a hollow structure, the fixing part 121 is movably disposed in the first connecting frame 1, the fixing part 121 is provided with a mounting hole 122, and the sliding member 11 is fixedly disposed in the mounting hole 122; the side of the hollow structure is provided with a first sliding groove 13, and the sliding member 11 passes through the first sliding groove 13.

[0052] In the above technical solution, the fixing part 121 provides a mounting base for the sliding part 11, and the sliding part 11 is mounted on the fixing part 121, so that the fixing part 121 drives the sliding part 11 to slide together. The first end of the first connecting frame 1 is a hollow structure, which provides mounting space for the fixing part 121 and guides the sliding of the fixing part 121, ensuring that the fixing part 121 and the sliding part 11 on it can only slide along the extension direction of the first connecting frame 1. The mounting hole 122 is used to fix the sliding part 11, ensuring that it can maintain correct alignment and sliding with the limiting groove 21 when the fixing part 121 moves, avoiding unstable shaking or displacement during the lifting process. The first sliding groove 13 is set on the side of the hollow structure of the first connecting frame 1, providing a guide path for the sliding part 11, ensuring that it can slide smoothly along the limiting groove 21 when the lifting assembly 12 moves up and down, making the movement of the sliding part 11 smoother and more accurate.

[0053] In one embodiment of the present invention, a mounting base 14 is fixedly provided inside the first connecting frame 1, and a fixing part 121 is slidably provided inside the mounting base 14. A second sliding groove 15 corresponding to the first sliding groove 13 is provided on the mounting base 14, and a sliding member 11 passes through the first sliding groove 13 and the second sliding groove 15.

[0054] In the above technical solution, the mounting base 14 is fixedly disposed within the first connecting frame 1 to accommodate and guide the fixing part 121, further improving the accuracy of the movement of the fixing part 121 and preventing the fixing part 121 from shifting or jamming during movement. The second slide groove 15 ensures that the sliding member 11 can pass through the mounting base 14 and cooperate with the external structure. The position and size of the second slide groove 15 are set to correspond to the first slide groove 13. The sliding member 11 passes through the first slide groove 13 and the second slide groove 15. The first slide groove 13 and the second slide groove 15 together guide the movement of the sliding member 11 and limit the extreme positions of the lifting and lowering of the sliding member 11, thereby improving the accuracy and reliability of the lifting and lowering movement of the sliding member 11.

[0055] In one embodiment of the present invention, an elastic member 17 is provided at the bottom of the fixing part 121, one end of the elastic member 17 abuts against the fixing part 121 and the other end abuts against the mounting base 14, and a pressing part 124 is also provided at the top of the fixing part 121, with the top end of the pressing part 124 being higher than the mounting base 14.

[0056] In the above technical solution, the elastic element 17 usually includes a spring, an elastic column, etc. The elastic element 17 is disposed at the bottom of the fixing part 121, one end of which abuts against the bottom of the fixing part 121, and the other end contacts the mounting base 14. When the user manually or automatically presses down the pressing part 124, the pressing part 124 pushes the fixing part 121 downward, compressing the elastic element 17 and converting kinetic energy into elastic potential energy for storage. During this process, the fixing part 121 drives the sliding element 11 downward, causing both ends of the sliding element 11 to disengage from the second limiting section 212 or the third limiting section 213 of the connecting part 2. At this time, the position of the support frame 4 can be adjusted by rotating it. When the user adjusts the support frame 4 to the desired folded or unfolded state, the user releases the pressing part 124. The elastic element 17, having lost pressure, returns to its original state, thereby releasing the elastic potential energy and pushing the fixing part 121 upward to reset. This, in turn, causes the sliding element 11 to move upward into the locking position within the second limiting section 212 or the third limiting section 213 of the connecting part 2, thus locking the support frame 4. The pressing part 124 is located at the top of the fixing part 121, and its top is designed to be higher than the mounting base 14, so that it is easier for the user to access and operate.

[0057] By incorporating a pressing part 124, the user can move the fixing part 121 simply by pressing, thereby causing the sliding part 11 to switch between the unlocked and locked positions. This design simplifies the operation process, allowing users to fold and unfold the rack without additional tools, thus improving the overall ease of use of the bicycle rack.

[0058] In the above embodiments, all of the fixing part 121 and the elastic member 17 and most of the sliding member 11 are located in the hollow structure of the first connecting frame 1, which does not occupy external space and effectively reduces the volume of the folding structure.

[0059] In one embodiment of this utility model, a mounting base 14 is fixedly provided inside the first connecting frame 1, and a locking member 16 is rotatably provided on the mounting base 14. The locking member 16 can engage with the lifting assembly 12.

[0060] In the above technical solution, the mounting base 14 can provide a stable mounting platform for the locking member 16. The locking member 16 is rotatably mounted on the mounting base 14. When the sliding member 11 is in the locked position, rotating the locking member 16 causes the locking member 16 to enter the locking position that engages with the lifting assembly 12, preventing the support frame 4 from accidentally folding or unfolding due to accidental contact with the pressing part 124. This improves the reliability of the bicycle rack, protects the safety of the bicycle and vehicle, and enhances the user experience.

[0061] In one embodiment of this utility model, two connectors 2 are spaced apart on the support frame 4, forming an installation space 22 between the two connectors 2, and the first connecting frame 1 is rotatably connected to the two connectors 2 within the installation space 22.

[0062] In the above technical solution, the two connecting pieces 2 are spaced apart, which not only disperses the load and improves the overall load-bearing capacity of the structure, but also serves as a fixed point for the support frame 4 to rotate, ensuring smooth and stable movement during folding and unfolding. The spaced arrangement also avoids stress concentration at a single connection point, extending the service life of the hanger. An installation space 22 is formed between the two connecting pieces 2, and the first connecting frame 1 is installed within the installation space 22 and rotatably connected to the two connecting pieces 2.

[0063] In one embodiment of the present invention, a gasket 36 is provided between the first connecting frame 1 and the connecting member 2. The gasket 36, the first connecting frame 1 and the mounting base 14 are all provided with connecting holes 37. A connecting member 38 is passed through the connecting hole 37. The gasket 36 is installed on the outside of the connecting member 2 through the connecting member 38, and the mounting base 14 is installed and fixed inside the connecting member 2.

[0064] In the above technical solution, the gasket 36, made of plastic or steel, can reduce local pressure at the connection point, prevent the first connecting frame 1 and the connecting member 2 from directly contacting and rotating relative to each other, thus avoiding wear and extending the service life of both. The connection hole 37 is formed in the gasket 36, the first connecting frame 1, and the mounting base 14, for inserting the through-connector 38. Common through-connectors 38 include bolts, pins, and bushings. Their main function is to install the gasket 36 on the outside of the first connecting frame 1 and simultaneously fix the mounting base 14 inside the connecting member 2, ensuring the stability of the mounting base 14.

[0065] In one embodiment of this utility model, the lifting assembly 12 is provided with a locking groove 18. Specifically, the locking groove 18 is provided on the pressing part 124. When the locking member 16 is in the locked state, the locking member 16 is engaged with the locking groove 18. When the locking member 16 is in the unlocked state, the locking member 16 is disengaged from the locking groove 18.

[0066] In the above technical solution, the locking member 16 is mainly used to cooperate with the locking groove 18 to lock the pressing part 124. When the user adjusts the support frame 4 to the desired folded or unfolded state, the locking member 16 is rotated to engage with the locking groove 18 to lock the pressing part 124, thereby preventing the pressing part 124 from being accidentally unlocked and thus preventing the support frame 4 from moving unexpectedly. In one embodiment of this utility model, the support frame 4 is provided with a beam support assembly 6, which includes a beam support body 61 and a beam support pad 62 disposed on the top of the beam support body 61. At least one side of the beam support body 61 is provided with a first pull strap 63. The beam support body 61 is provided with a mounting hole, and the support frame 4 passes through the mounting hole. The beam support body 61 is fixed to the support frame 4 by stepped screws.

[0067] In the above technical solution, the beam support assembly 6 in the bicycle mounting system is mainly used to stabilize and protect the bicycle, especially the frame. The beam support body 61 is the basic structure of the beam support, used to install and fix the beam support on the support frame 4, and also provides a mounting base for the beam support pad 62 and the first pull strap 63. The beam support pad 62 is in direct contact with the bicycle body, and its main function is to protect the bicycle frame from direct wear, while increasing friction to prevent the bicycle from sliding during transportation. Its material is generally chosen to absorb impact, prevent slippage, and minimize damage to the bicycle surface, such as rubber or EVA foam. The first pull strap is usually set on one or more sides of the beam support body, mainly used to support and fix other parts of the bicycle to prevent the bicycle from moving back and forth or swaying during transportation, thus improving the safety and stability of the bicycle mounting. The support frame 4 is provided with screw holes for mounting and fixing the support frame. After the beam support assembly 6 is sleeved on the support frame 4 and moved to the position corresponding to the screw hole, the beam support assembly 6 is locked and fixed with fasteners such as stepped screws. At the same time, the screw hole that mates with the stepped screw is a racetrack-shaped stepped screw groove, which can restrict the beam support assembly 6 from rotating in the circumferential direction.

[0068] In one embodiment of this utility model, the rotatable angle θ of the beam support assembly 6 on the support frame 4 is 58°.

[0069] In the above technical solution, the rotation angle θ of the beam support assembly 6 is set at 58°, mainly based on considerations of safety and ease of operation. This design ensures that the beam support assembly 6 can stably fix the bicycle during rotation, while avoiding potential collisions with the rear of the vehicle or other external structures, thus improving the stability and safety of the bicycle when it is mounted.

[0070] In one embodiment of the present invention, the beam support body 61 includes a first beam support member 64 and a second beam support member 65, which are connected by a snap fastener, screw, or bolt to form the beam support body 61.

[0071] In the above technical solution, the first beam support 64 and the second beam support 65 constitute the main structure of the beam support body. The split design facilitates the replacement of individual damaged or worn beam support components without replacing the entire beam support assembly. Clips, screws, or bolts are used to secure the first and second beam support components together, forming a complete beam support body. Clips provide a quick, tool-free connection method, suitable for temporary adjustments or rapid disassembly; while screws ensure long-term stability and robustness, suitable for more durable fixing needs. By selecting appropriate connection methods, the beam support assembly can meet both immediate adaptive adjustments and ensure safety and reliability during long-term use.

[0072] In one embodiment of the present invention, a first button 66 is also provided on the beam support body 61. The first button 66 can control the first pull strap 63 to switch between locked and unlocked states. The first button 66 and the first pull strap 63 are respectively installed on the beam support body 61 with different screws.

[0073] In the above technical solution, the first button 66 is used to control the first pull strap 63 to switch between locked and unlocked states. By setting the first button 66, the user can quickly unlock and adjust the pull strap, and then lock it again, without the need for complicated tools or cumbersome operations, thus improving the convenience of mounting the bicycle. The first button 66 and the first pull strap 63 are respectively installed on the beam support body 61 with different screws. The independent installation of the first button 66 and the first pull strap 63 avoids misoperation that may be caused by mutual interference between components during operation, increasing the reliability of the system and the accuracy of operation. At the same time, it is convenient to replace individual first buttons 66 and first pull straps 63 that are damaged or worn. Compared with the design of the first button 66 and the first pull strap 63 being installed and fixed as a whole, the independent installation of the first button 66 and the first pull strap 63 does not require the replacement of the entire first button 66 and the first pull strap 63, reducing the difficulty and cost of maintenance.

[0074] In one embodiment of the present invention, the support frame 4 is further provided with a side support assembly 7, which is rotatably connected to the beam support assembly 6. The side support assembly 7 includes a side support body 71, and at least one side of the side support body 71 is provided with a second pull strap 72.

[0075] In the above technical solution, the side support assembly 7 is mainly designed to increase the stability and safety of the bicycle during loading, preventing lateral or longitudinal swaying of the bicycle during riding, thereby avoiding collisions between bicycles or damage to the bicycle. Through its rotatable connection with the beam support assembly 6, the side support assembly 7 can adjust its angle with the beam support assembly 6 according to bicycles of different sizes and shapes, improving the adaptability of the side support assembly 7. It can also be folded up when not in use, reducing space occupation. The side support body 71 is the basic structure of the side support assembly 7, providing a mounting base for the second pull strap 72. The second pull strap 72 is located on at least one side of the side support body, used to directly fix the side of the bicycle, such as the frame's triangle or the bar under the seat. The use of the second pull strap effectively restricts the lateral or longitudinal movement of the bicycle, enhancing the stability of the bicycle load.

[0076] In one embodiment of the present invention, the side support assembly 7 is rotatable relative to the beam support assembly 6 to switch between an unfolded position and a retracted position. When the side support assembly 7 is in the retracted position, the first pull strap 63 and the second pull strap 72 are parallel. When the side support assembly 7 is in the unfolded position, the first pull strap 63 and the second pull strap 72 are set at an angle, preferably 90°.

[0077] In the above technical solution, the side support assembly 7 can rotate relative to the beam support assembly 6, thereby switching between the extended and retracted positions. This design aims to enhance the overall stability and space management capabilities of the bicycle rack. When the side support assembly is in the retracted position, the first pull strap 63 and the second pull strap 72 are parallel, minimizing the size of the rack and facilitating storage when not in use. In the extended position, the two pull straps are set at a 90° angle, forming stronger lateral and longitudinal constraints, effectively preventing the bicycle from swaying and moving back and forth during riding, and improving the reliability and stability of the bicycle rack.

[0078] In one embodiment of this utility model, a side support pad 73 is also provided on the side support body 71.

[0079] In the above technical solution, the side support pad 73 is in direct contact with the bicycle. Its material is usually a soft and cushioning material, such as rubber or high-density foam, which is intended to reduce the hard contact between the side of the bicycle and the rack, effectively absorb vibration, prevent scratches and wear, and protect the surface paint of the bicycle from damage.

[0080] In one embodiment of the present invention, a second button 74 is also provided on the side support body 71. The second button 74 can control the second pull strap 72 to switch between locked and unlocked states. The second button 74 and the second pull strap 72 are respectively installed on the side support body 71 with different screws.

[0081] In the above technical solution, the second button 74 is used to control the second pull strap 72 to switch between locked and unlocked states. By setting the second button 74, the user can quickly unlock and adjust the pull strap, and then lock it again, without the need for complicated tools or cumbersome operations, thus improving the convenience of mounting the bicycle. The second button 74 and the second pull strap 72 are respectively installed on the side support body 71 with different screws. The independent installation of the second button 74 and the second pull strap 72 avoids misoperation that may be caused by mutual interference between components during operation, increasing the reliability of the system and the accuracy of operation. At the same time, it is convenient to replace individual damaged or worn second buttons 74 and second pull straps 72. Compared with the design of the second button 74 and the second pull strap 72 being installed and fixed as a whole, the independent installation of the second button 74 and the second pull strap 72 does not require the replacement of the entire second button 74 and the second pull strap 72, reducing the difficulty and cost of maintenance.

[0082] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: The first connecting frame 1 is one of the main support structures of the bicycle rack, used to connect the rear of the car and the support frame, ensuring that the rack can be firmly fixed to the car. At the same time, the first connecting frame 1 provides support for the support frame 4. The second connecting frame 5 is used to connect the first connecting frame 1 to the trailer structure at the rear of the vehicle, ensuring that the rack is firmly attached to the vehicle. The first end of the first connecting frame 1 is provided with a sliding member 11, and the first end of the support frame 4 is provided with a connecting member 2. The sliding member 11 and the connecting member 2 are slidably connected. Through the sliding cooperation between the sliding member 11 and the connecting member 2, the support frame 4 can switch between a folded state and an unfolded state. At the same time, the support frame in the folded or unfolded state is limited and fixed to ensure that the support frame 4 will not loosen. The support frame 4 is used to carry the bicycle. When the support frame 4 is folded, its volume is reduced, reducing space occupation and making it more suitable for storage. When unfolded, it provides sufficient space to carry the bicycle, ensuring the bicycle's fixation and safety.

[0083] The bicycle rack provided by this utility model allows the support frame 4 to switch between a folded state and an unfolded state by setting a sliding member 11 and a connecting member 2. Compared with the existing folding structure of pneumatic rods, hydraulic rods or connecting blocks and connecting plates, the volume of the folding structure is significantly reduced, thereby solving the problem of the large volume of the existing bicycle rack folding structure and reducing the space occupied by the folding structure.
