Description

Technical Field

[0001] The utility model relates to the technical field of bicycle frames, in particular to a bicycle frame with reinforcing ribs inside. Background Art

[0002] The frame components are the basic structure of the bicycle, and are also the skeleton and main body of the bicycle. Other components are also directly or indirectly installed on the frame. Since the bicycle relies on the human body's own driving force to travel, the frame becomes an important structure that withstands the impact load generated by the bicycle during travel and whether it can carry the human body comfortably and safely.

[0003] Chinese patent publication number CN216102594U, published on March 22, 2022, discloses a bicycle frame comprising a main frame and a subframe cooperating with the main frame. The main frame and the subframe are connected by fasteners, and adhesive is coated on the contact surfaces of the two. Reinforcing ribs are provided in both the main frame and the subframe.

[0004] For example, in the above-mentioned disclosed patents, due to the influence of weight and wind resistance, most existing bicycle frames directly eliminate mudguards. That is, if mudguards are to be installed later, they need to be equipped with corresponding fastening components. The mudguards cannot be conveniently disassembled and assembled according to usage requirements, thereby increasing the limitations of the use of bicycle frames. Therefore, it is urgent to propose corresponding bicycle frames with internal reinforcing ribs to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to solve the above problems and to provide a bicycle frame with internal reinforcing ribs.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A bicycle frame with internal reinforcing ribs includes a seat connecting frame, a crossbeam, a support beam and a mudguard. The seat connecting frame, the crossbeam and the support beam are fixedly connected. Two groups of upper fork arms and lower fork arms are fixedly connected to the outer walls of the crossbeam and the support beam respectively. A reinforcing seat is fixedly connected between the two groups of upper fork arms, and the outer wall of the reinforcing seat is provided with an installation component for installing the mudguard.

[0008] Preferably, the mounting assembly includes a connecting plate, the connecting plate is fixedly connected to the outer wall of the arc-shaped end of the fender, and the connecting plate is detachably connected to the reinforcement seat.

[0009] Preferably, the outer wall of the connecting plate is engaged with the inner wall of the reinforcing seat through a slot, and the connecting plate and the reinforcing seat are fixedly connected by a locking rod.

[0010] Preferably, a rubber pad is interference-fitted inside the connecting plate, and the inner surface wall of the rubber pad abuts against the outer surface wall of the locking rod.

[0011] Preferably, a liner with a triangular structure is fixedly connected between the outer wall of the connecting plate and the outer wall of the arc-shaped end of the fender.

[0012] Preferably, the cross beam and the support beam are fixedly connected to the seat connecting frame with a first reinforcing rib, and the seat connecting frame, the cross beam and the support beam are fixedly connected inside with a second reinforcing rib.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0014] 1. In the present application, the structural strength of the entire frame is ensured by connecting the second reinforcing rib inside the seat connecting frame, the cross beam and the support frame in conjunction with the first reinforcing rib connected between the cross beam, the support beam and the seat connecting frame. The reinforcing seat is connected between the two sets of upper fork arms, thereby increasing the structural strength of the two sets of upper fork arms. The connecting plate is fixed to the reinforcing seat by a locking rod, thereby enabling the installation of the mudguard. The reinforcing seat further ensures the structural strength of the bicycle frame while allowing the frame to be quickly disassembled and assembled as needed, thereby improving the convenience of using the bicycle frame.

[0015] 2. In the present application, after the connection plate and the reinforcement seat are fixed by the locking rod, the rubber pad can be inserted into the connection plate. The interference fit ensures the stability of the position of the rubber pad. The rubber pad can isolate the locking rod. At the same time, the friction generated between the rubber pad and the locking rod can limit the loosening of the locking rod, thereby improving the stability of the bicycle frame with internal reinforcement ribs.

[0023] See also Figure 1-4 , the utility model provides a technical solution:

[0024] A bicycle frame with internal reinforcement ribs includes a seat connecting frame 1, a crossbeam 2, a support beam 3, and a fender 9. The seat connecting frame 1, crossbeam 2, and support beam 3 are fixedly connected. Two sets of upper fork arms 4 and lower fork arms 5 are fixedly connected to the outer walls of the crossbeam 2 and support beam 3, respectively. A reinforcement seat 6 is fixedly connected between the two sets of upper fork arms 4, and the outer wall of the reinforcement seat 6 is provided with a mounting assembly for mounting the fender 9.

[0025] By connecting the second reinforcing rib inside the seat connecting frame 1, the cross beam 2 and the support beam 3, and cooperating with the first reinforcing rib 7 connected between the cross beam 2, the support beam 3 and the seat connecting frame 1, the overall structural strength of the frame is ensured. The reinforcing seat 6 is connected between the two sets of upper fork arms 4, increasing the structural strength of the two sets of upper fork arms 4. The connecting plate 8 is fixed to the reinforcing seat 6 by the locking rod 13, so that the installation of the mudguard 9 can be realized. While the structural strength of the bicycle frame is further ensured by the reinforcing seat 6, the mudguard 9 can be quickly disassembled and assembled as needed, thereby improving the convenience of using the bicycle frame.

[0026] Specifically, such as Figure 2 and Figure 4 As shown, the installation assembly includes a connecting plate 8, which is fixedly connected to the outer wall of the arc-shaped end of the fender 9, and is detachably connected to the reinforcement seat 6. The outer wall of the connecting plate 8 is engaged with the inner wall of the reinforcement seat 6 through the card slot 11, so as to facilitate the rapid alignment of the connecting plate 8 and the reinforcement seat 6, and the connecting plate 8 and the reinforcement seat 6 are fixedly connected by the locking rod 13, which ensures the convenience of disassembly and assembly of the connecting plate 8.

[0027] Specifically, such as Figure 2 and Figure 3As shown, a rubber pad 12 is interference-fitted inside the connecting plate 8, and the inner wall of the rubber pad 12 abuts against the outer wall of the locking rod 13. After the connecting plate 8 and the reinforcement seat 6 are fixed by the locking rod 13, the rubber pad 12 can be inserted into the connecting plate 8. The interference fit method ensures the stability of the position of the rubber pad 12. The rubber pad 12 can isolate the locking rod 13, and the friction generated between the rubber pad 12 and the locking rod 13 can limit the loosening of the locking rod 13, thereby improving the stability of the bicycle frame with internal reinforcement ribs.

[0028] Specifically, such as Figure 1 and Figure 2 As shown, a triangular-shaped liner 10 is fixedly connected between the outer wall of the connecting plate 8 and the outer wall of the curved end of the fender 9 to ensure the structural strength between the connecting plate 8 and the fender 9. A reinforcing rib 7 is fixedly connected between the cross beam 2 and the support beam 3 and the seat connecting frame 1, and a reinforcing rib 2 is fixedly connected inside the seat connecting frame 1, the cross beam 2 and the support beam 3. By connecting the reinforcing rib 2 inside the seat connecting frame 1, the cross beam 2 and the support beam 3, in combination with the reinforcing rib 7 connected between the cross beam 2, the support beam 3 and the seat connecting frame 1, the overall structural strength of the frame is ensured.

[0029] Working principle: The two reinforcing ribs connected inside the seat connecting frame 1, the cross beam 2 and the support beam 3, in conjunction with the reinforcing rib 1 7 connected between the cross beam 2, the support beam 3 and the seat connecting frame 1, ensure the overall structural strength of the frame. The reinforcing seat 6 is connected between the two sets of upper fork arms 4, increasing the structural strength of the two sets of upper fork arms 4. The connecting plate 8 is fixed to the reinforcing seat 6 by the locking rod 13, so that the installation of the mudguard 9 can be realized. While the structural strength of the bicycle frame is further ensured by the reinforcing seat 6, the mudguard 9 can be quickly disassembled and assembled as needed, thereby improving the convenience of using the bicycle frame. After the connecting plate 8 and the reinforcing seat 6 are fixed by the locking rod 13, the rubber pad 12 can be inserted into the connecting plate 8. The interference fit method ensures the stable position of the rubber pad 12. The rubber pad 12 can isolate the locking rod 13 while the friction generated between the rubber pad 12 and the locking rod 13 can limit the loosening of the locking rod 13, thereby improving the stability of the bicycle frame with internal reinforcing ribs.
