Description

Technical Field

[0001] The embodiments of this utility model relate to the field of integrated luggage rack technology for bicycles, and more specifically, this utility model relates to an integrated luggage rack for bicycles. Background Technology

[0002] Bicycles, as a convenient and environmentally friendly means of transportation, have been widely used around the world. However, over the long term, problems have gradually emerged, such as insufficient support strength of the rear seat when carrying people or goods and the inability to effectively protect the rear wheel.

[0003] In existing technologies, integrated bicycle racks are typically single-frame structures. While this design meets basic load-bearing requirements to some extent, it often lacks sufficient support strength when dealing with heavier people or objects. Specifically, integrated racks are prone to deformation under stress, and may even break down due to their inability to withstand excessive pressure. This not only affects the normal use of the bicycle but may also pose a serious threat to the rider's safety.

[0004] Furthermore, the existing bicycle rear seat design has a significant flaw: it fails to provide effective protection for the rear wheel. During riding, the rear wheel is easily subjected to impacts or scrapes from behind, which can not only damage the rear wheel but also potentially cause traffic accidents. Utility Model Content

[0005] In order to solve one or more of the technical problems mentioned above, this utility model provides an integrated luggage rack for bicycles, which can improve the support strength of the bicycle's rear seat and also cover part of the rear wheel to protect it.

[0006] This utility model embodiment provides an integrated luggage rack for bicycles, comprising:

[0007] The rear seat support has a load-bearing surface on it;

[0008] The main frame is arranged parallel to the bearing surface and covers the bearing surface;

[0009] Two side frames are symmetrically and detachably mounted on both sides of the rear seat support along the direction of travel of the bicycle. Each side frame includes a first frame fixedly connected to the main frame and a connecting frame connected to the first frame and the main frame respectively.

[0010] The rear seat support can distribute some of the pressure on the bearing surface. The first frame includes a connecting end connected to the main frame, a first covering end located on the side connected to the connecting frame, and a second covering end further away from the main frame than the connecting end. The connecting end is connected to the side of the main frame near the bicycle seat, and the connecting frame is connected to the side of the main frame away from the bicycle seat. The connecting end, the first covering end, and the second covering end can form a covering area that covers part of the rear wheel of the bicycle.

[0011] Furthermore, the first frame is a triangular structure, and the connecting end, the first covering end, and the second covering end correspond to the three vertices of the triangular structure, respectively.

[0012] Furthermore, the area of ​​the coverage region mapped onto the rear wheel is at least one-fifth of the area of ​​the rear wheel, and the second coverage end is located closer to the center of the rear wheel.

[0013] Furthermore, the side frame also includes a reinforcing frame that is connected to the first frame at both ends and divides the triangular structure into a triangular region and a trapezoidal region.

[0014] Furthermore, the side frame also includes a connecting lug disposed on the first frame and located within the triangular area, and a first fastening bolt passing through the connecting lug and the rear seat bracket and threadedly connected to the rear seat bracket.

[0015] Furthermore, the rear seat support includes:

[0016] A support frame, on which a support surface is provided;

[0017] A connecting pipe, one end of which is connected to the tube of the bicycle, and the other end of which is connected to the rear wheel of the bicycle;

[0018] The first support pipe has one end connected to the bearing frame and the other end connected to the connecting pipe, and provides support for the bearing frame;

[0019] A reinforcing pipe has one end connected to the vehicle pipe and the other end connected to the connecting pipe, and is inclined relative to the connecting pipe.

[0020] The second support pipe has one end connected to the reinforcing pipe and the other end connected to the support frame.

[0021] Furthermore, the main frame includes a second frame that can completely cover the bearing surface of the rear seat bracket and is used for connecting the first frame and the connecting frame, and a support frame disposed in the hollow area of ​​the second frame and connected to the second frame at both ends, wherein the hollow area is the inner side of the second frame.

[0022] Furthermore, the rear seat bracket also includes a second fastening bolt that passes sequentially through the second frame and the support frame and is threadedly connected to the support frame.

[0023] Furthermore, the second frame is a rectangular structure.

[0024] Furthermore, the integrated luggage rack also includes a fastening assembly, which includes a rope and hooks at both ends of the rope. The side frame also includes a hanging lug on the second cover end for hooking the hooks.

[0025] The integrated luggage rack for bicycle rear seats provided in this embodiment has a main frame and side frames detachably mounted on both sides of the rear seat support for selective installation according to actual needs. The main frame covers the load-bearing surface, preventing external forces from directly damaging it and providing some protection. Furthermore, the addition of the main frame to the original rear seat support increases the support strength of the bicycle rear seat, thus meeting the user's load-bearing needs when supporting heavier people or objects. The covering area formed by the connecting end, the first covering end, and the second covering end of the side frame prevents external forces from directly acting on the portion of the bicycle's rear wheel covered by the covering area. Moreover, existing rear seat supports generally rely on individual tubing and cannot form a complete area. When the rear seat needs to support heavy people or objects, the pressure acting directly on the individual tubing can easily cause deformation. Therefore, the side frame, by utilizing the entire first frame with a covered area, distributes the pressure on the rear seat across the entire first frame, thus providing good support for the main frame. In addition, the rear support can also distribute some of the pressure on the bearing surface, thus working together with the main frame and side frames to improve the load-bearing capacity of the main frame.

[0035] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0036] Figure 1 This embodiment shows a schematic diagram of the structure of an integrated luggage rack for bicycles. Figure 2 A schematic diagram of the main frame 2, side frame 3, and fastening assembly 4 provided in this embodiment is shown. Figures 1-2As shown, this embodiment provides an integrated luggage rack for a bicycle, which includes a rear seat support 1, a main frame 2, and two side racks 3. The rear seat support 1 has a bearing surface 111. The main frame 2 is arranged parallel to the bearing surface 111 and covers the bearing surface 111. The two side racks 3 are symmetrically and detachably arranged on both sides of the rear seat support 1 along the direction of bicycle travel. The side rack 3 includes a first frame 31 fixedly connected to the main frame 2 and a connecting frame 32 connected to the first frame 31 and the main frame 2 respectively. The rear seat support 1 can distribute the pressure on part of the bearing surface 111. The first frame 31 includes a connecting end 311 connected to the main frame 2, a first covering end 312 located on the side connected to the connecting frame 32, and a second covering end 313 further away from the main frame 2 than the connecting end 311. The connecting end 311 is connected to the side of the main frame 2 near the bicycle seat, and the connecting frame 32 is connected to the side of the main frame 2 away from the bicycle seat. The connecting end 311, the first covering end 312, and the second covering end 313 can form a covering area that covers part of the rear wheel 100 of the bicycle.

[0037] The integrated luggage rack for bicycle rear seats provided in this embodiment has a main frame 2 and side frames 3 detachably mounted on both sides of the rear seat support 1 for selective installation according to actual needs. The main frame 2 covers the bearing surface 111, which on the one hand prevents external forces from directly acting on the bearing surface 111 of the rear seat support 1 and causing damage to the bearing surface 111, thus providing a certain degree of protection for the bearing surface 111. On the other hand, the addition of the main frame 2 to the original rear seat support 1 also improves the support strength of the bicycle rear seat, thereby meeting the user's bearing needs when facing heavier people or objects. The covering area formed by the connecting end 311, the first covering end 312, and the second covering end on the side frame 3 serves two purposes. First, it prevents external forces from directly acting on the portion of the bicycle's rear wheel 100 covered by the covering area. Second, existing rear seat supports 1 generally rely on individual tubes and cannot form a complete area. When the rear seat needs to support a heavy person or object, the pressure acting directly on the individual tubes can easily cause deformation. Therefore, the side frame 3 distributes the pressure on the rear seat across the entire first frame 31 with the covering area, thus providing good support for the main frame 2. In addition, the rear seat support 1 can also distribute some of the pressure on the bearing surface 111, thereby working together with the main frame 2 and the side frame 3 to improve the load-bearing capacity of the main frame 2.

[0038] Furthermore, the first frame 31 is a triangular structure, with the connecting end 311, the first covering end 312, and the second covering end 313 corresponding to the three vertices of the triangular structure. By utilizing the inherent stability characteristics of the triangular structure, the structural strength of the first frame 31 is significantly enhanced, thereby providing a more solid and reliable support effect for the main frame 2.

[0039] Furthermore, the area of ​​the coverage area mapped onto the rear wheel 100 is at least one-fifth of the area of ​​the rear wheel 100, and the second coverage end 313 is set closer to the center of the rear wheel 100. While ensuring that the coverage area can effectively resist the impacts and scratches that the rear wheel 100 often encounters during riding (especially most of the impacts and scratches that occur on the upper part of the rear wheel 100), this setting can also provide stable support for the main frame 2 without affecting the overall aesthetics of the bicycle rear seat.

[0040] Furthermore, the side frame 3 also includes a reinforcing frame 33 that is connected to the first frame 31 at both ends and divides the triangular structure into a triangular region and a trapezoidal region. The reinforcing frame 33 provides support for the first frame 31, reduces the possibility of the first frame 31 being deformed by external forces, and thus improves the overall structural strength of the side frame 3.

[0041] In this embodiment, the side frame 3 further includes a connecting ear 34 disposed on the first frame 31 and located within the triangular region, and a first fastening bolt 35 passing through the connecting ear 34 and the rear seat bracket 1 and threadedly connected to the rear seat bracket 1. The connecting ear 34 is a connecting piece provided by the first frame 31 to connect with the rear seat bracket 1. By screwing the first fastening bolt 35 into the connecting ear 34 and the rear seat bracket 1, the side frame 3 can be stably fixed to the rear seat bracket 1 while achieving a detachable connection, thereby ensuring that the integrated luggage rack can effectively protect the rear seat bracket 1. In other embodiments, the side frame 3 can also be detachably connected in other ways that can achieve the above effects, and this embodiment does not specifically limit this. All detachable connection methods that can achieve the above effects should be within the protection scope of the embodiments disclosed herein.

[0042] Figure 3 A schematic diagram of the structure of the rear seat bracket 1 provided in this embodiment is shown. Figure 3 and combined Figure 1 and Figure 2As shown, the rear seat support 1 includes a support frame 11, a connecting pipe 12, a first support pipe 13, a reinforcing pipe 14, and a second support pipe 15. The support frame 11 has a bearing surface 111. One end of the connecting pipe 12 is connected to the bicycle's tube 200, and the other end is connected to the bicycle's rear wheel 100. One end of the first support pipe 13 is connected to the support frame 11, and the other end is connected to the connecting pipe 12, providing support for the support frame 11. One end of the reinforcing pipe 14 is connected to the tube 200, and the other end is connected to the connecting pipe 12, and it is inclined relative to the connecting pipe 12. One end of the second support pipe 15 is connected to the reinforcing pipe 14, and the other end is connected to the support frame 11. The pressure generated by the support frame 11 when bearing heavy objects is effectively transmitted through the first support pipe 13 and the second support pipe 15, and acts on the connecting pipe 12 and the reinforcing pipe 14 respectively. The reinforced tube 14, with its sloping structure, not only cleverly distributes the pressure to the connecting tube 12 and the frame body, reducing the load on a single component, but also plays an indispensable supporting role, effectively avoiding the risk of breakage that may occur when the integrated luggage rack is carrying heavy loads, thus ensuring the safety and comfort of riding.

[0043] Furthermore, the main frame 2 includes a second frame 21 that can completely cover the bearing surface 111 of the rear seat support 1 and connect the first frame 31 and the connecting frame 32. The second frame 21, which completely covers the bearing surface 111, ensures that the main frame 2 provides comprehensive protection for the bearing surface 111, thereby improving the protective effect of the main frame 2. It also includes a support frame 22 located within the hollow area 211 of the second frame 21 and connected to the second frame 21 at both ends. The hollow area 211 is the inner side of the second frame 21, providing support for the second frame 21 through the support frame 22, reducing the possibility of deformation of the second frame 21 under external forces, thereby improving the overall structural strength of the main frame 2.

[0044] Furthermore, the rear seat bracket 1 also includes a second fastening bolt that passes through the second frame 21 and the support frame 11 in sequence and is threadedly connected to the support frame 11. The second fastening bolt connects the second frame 21 and the support frame 11, which can both enable the disassembly of the support frame 11 from the second frame 21 and ensure that the support frame 11 is stably connected to the second frame 21 to ensure effective protection and support for the main frame 2 and the side frame 3.

[0045] Preferably, multiple second fastening bolts are provided, with each support frame 22 corresponding to one second fastening bolt, so as to further ensure that the main frame 2 and the side frame 3 can effectively protect and support the rear seat support 1.

[0046] Preferably, the second frame 21 is a rectangular structure to ensure that the second frame 21 has a stable supporting effect.

[0047] Furthermore, the integrated luggage rack also includes a fastening component 4, which includes a rope 41 and hooks 42 disposed at both ends of the rope 41. The side frame 3 also includes a hanging lug 36 disposed on the second cover end 313 for the hooks 42 to hook onto. The hooks 42 and the rope 41 ensure that the fastening component 4 can fasten the fasteners and also facilitate user assembly and disassembly, thereby improving the user experience. In other embodiments, the fastening component 4 may also be a separate rope 41, with both ends of the rope 41 directly tied to the first frame 31, or other fastening components 4 with a fastening effect. This embodiment does not specifically limit this. Any fastening component 4 that can achieve the above effects should be within the protection scope of the embodiments disclosed herein.
