Description
Technical Field
[0001] This utility model relates to the field of vehicle-mounted bicycle brackets, and more specifically, it relates to a bicycle bracket. Background Technology
[0002] A Chinese patent with publication number CN117622009A discloses a pivotable bicycle bracket, which includes a bicycle support plate assembly, wheel retaining arms, retaining arm pivot locks, and a pull rod assembly; the retaining arm pivot locks act on a strut between each wheel retaining arm and the plate to which each wheel retaining arm is attached; the pull rod assembly is attached to the bicycle support plate assembly, and the pull rod assembly includes a pull rod for attaching a receiver to a tubular trailer.
[0003] However, the bicycle bracket in the above patent still has the following problems: 1. The force of the wheel retaining arm is transmitted to the bicycle support plate assembly through the strut and retaining arm pivot lock, and then transmitted to the pull rod assembly by the bicycle support plate assembly. If it carries a heavy vehicle, such as an electric bicycle, the stability of the bicycle bracket is insufficient; 2. The wheel retaining arm can only limit one side of the wheel, resulting in insufficient stability of the bicycle. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a bicycle bracket that can improve the load-bearing capacity and stability of the bracket, thus making it suitable for bicycles with larger weights.
[0005] To achieve the above objectives, the present invention provides the following technical solution: A bicycle support bracket includes a support base, a wheel support plate, an outer wheel limit bracket, and a support arm; The far end of the wheel support plate is rotatably connected to the outer wheel limiting frame, and the near end is connected to the support base. The distal end of the support arm is rotatably connected to the outer wheel limit frame, and the proximal end is rotatably connected to the support base.
[0006] Furthermore, a first support shaft is provided between the support base, the wheel support plate, and the support arm; Alternatively, a first support shaft may be provided between the support base and the wheel support plate, and between the support base and the support arm.
[0007] Furthermore, the support base includes a support base plate and two support vertical plates; the wheel support plate is embedded between the two support vertical plates, and the support arm is located on the outside of the support base.
[0008] Furthermore, the first support shaft passes sequentially through the support arm, one of its support vertical plates, the wheel support plate, and another support vertical plate.
[0009] Furthermore, a limiting structure is provided between the support base and the wheel support plate.
[0010] Furthermore, the limiting structure includes a limiting shaft, which is parallel to the first support shaft.
[0011] Furthermore, the wheel support plate has a cavity, and a reinforcing plate is provided inside the cavity; the reinforcing plate has a clearance groove for the first support shaft to pass through.
[0012] Furthermore, the support arm includes a support tube and a support rod passing through the support tube; a one-way locking structure or a two-way locking structure is provided between the support tube and the support rod.
[0013] Furthermore, the one-way locking structure includes a one-way rack disposed on the side wall of the support rod and a lock head disposed on the support tube; an elastic element is disposed between the lock head and the support tube, and the elastic force of the elastic element causes the lock head to have a tendency to rotate to engage with the one-way rack.
[0014] Furthermore, the bicycle bracket also includes an inner wheel retainer mounted on the wheel plate.
[0015] Furthermore, the inner wheel limiting frame includes a limiting base and a limiting groove plate rotatably connected to the limiting base.
[0016] Furthermore, the position of the limiting base relative to the wheel support plate is adjustable.
[0017] In summary, this utility model has the following beneficial effects: 1. Connect the near end of the support arm to the support base, bypassing the wheel tray, and let the support base directly bear the stress. This can effectively improve the load-bearing capacity and stability of the bracket. 2. A first support shaft is inserted between the support base, wheel support plate and support arm, which simplifies the structure, reduces the number of parts and assembly steps, and lowers the cost; 3. When in the unfolded state, the first support shaft cooperates with the limiting shaft, which on the one hand prevents the wheel support plate from rotating relative to the support base, and on the other hand improves the load-bearing capacity and stability of the bracket. 4. The use of reinforcing plates can improve the structural strength of the wheel support plate, thereby improving the load-bearing capacity and stability of the bracket; passing the first support shaft, the limiting shaft and the second support shaft through the reinforcing plates can further improve the structural strength, load-bearing capacity and stability of the bracket. 5. The inner wheel limit bracket is installed on the wheel support plate and works in conjunction with the outer wheel limit bracket to limit and fix a wheel, thereby improving the stability of the vehicle.

[0023] Reference Figures 1 to 5In this embodiment, the far end of the wheel support plate 2 is rotatably connected to the outer wheel limit frame 3, and the near end is connected to the support base 11; the far end of the support arm 4 is rotatably connected to the outer wheel limit frame 3, and the near end is rotatably connected to the support base 11; that is, by connecting the near end of the support arm 4 to the support base 11, the wheel support plate 2 is bypassed, and the stress is directly borne by the support base 1, which can effectively improve the load-bearing capacity and stability of the bracket.
[0024] Reference Figures 1 to 5 Preferably, a first support shaft 61 is provided between the support base 11, the wheel support plate 2, and the support arm 4; that is, the stress of the wheel support plate 2 is transmitted to the support base 11 via the first support shaft 61, and the stress of the support arm 4 is transmitted to the support base 11 via the first support shaft 61. This simplifies the structure, reduces the number of parts and assembly steps, and lowers the cost. Of course, in other optional embodiments, the first support shaft can also be provided between the support base 11 and the wheel support plate 2, and between the support base 11 and the support arm 4, respectively. This is not a limitation.
[0025] Reference Figures 1 to 5 Preferably, the support base 11 includes a support base plate 111 and two support vertical plates 112; the wheel support plate 2 is embedded between the two support vertical plates 112, and the support arm 4 is located on the outside of the support base 11; the first support shaft 61 passes through the support arm 4, one support vertical plate 112, the wheel support plate 2, and the other support vertical plate 112 in sequence; the wheel support plate 2 is embedded between the two support vertical plates 112, and the support vertical plates 112 provide limiting support for the wheel support plate 2, which can improve the stability of the bracket; the first support shaft 61 passes through the two support vertical plates 112 respectively, so the first support shaft 61 and the support base 11 form two force points, which can also improve the load-bearing capacity and stability of the bracket.
[0026] Reference Figures 1 to 5 In this embodiment, the first support shaft 61 also serves as the pivot shaft for the support arm 4 and the wheel support plate 2 respectively; that is, the support arm 4 can rotate around the first support shaft 61, and the wheel support plate 2 can rotate around the first support shaft 61, thereby realizing the folding of the bracket; in this embodiment, one end of the first support shaft 61 is provided with a bolt head, and the other end is screwed with a nut, thereby realizing axial fixation.
[0027] Reference Figures 1 to 5 A second support shaft 63 is provided between the outer wheel limit frame 3 and the wheel support plate 2 to achieve a rotatable connection; one end of the second support shaft 63 is provided with a bolt head, and the other end is screwed with a nut to achieve axial fixation.
[0028] Reference Figures 1 to 5In this embodiment, a limiting structure is provided between the support base 11 and the wheel support plate 2. In the unfolded state, the limiting structure prevents the wheel support plate 2 from rotating and also improves the load-bearing capacity and stability of the bracket. Specifically, the limiting structure includes a limiting shaft 62, which is parallel to the first support shaft 61. The limiting shaft 62 passes through one support vertical plate 112, the wheel support plate 2, and another support vertical plate 112 in sequence, thus forming two force points between the limiting shaft 62 and the support base 11. In the unfolded state, the first support shaft 61 cooperates with the limiting shaft 62, which on the one hand prevents the wheel support plate 2 from rotating relative to the support base 11, and on the other hand improves the load-bearing capacity and stability of the bracket. One end of the limiting shaft 62 is provided with a bolt head, and the other end is screwed with a nut to achieve axial fixation. If the wheel support plate 2 needs to be folded, the limiting shaft 62 can be removed first, and then the wheel support plate 2 can be rotated, which is convenient to operate.
[0029] Reference Figures 1 to 5 Preferably, the wheel support plate 2 has a cavity extending along its length, and a reinforcing plate 21 extending along its length is provided in the cavity; specifically, in this embodiment, the wheel support plate 2 has two spaced cavities, and each cavity is provided with a reinforcing plate 21; preferably, the reinforcing plate 21 is provided with clearance grooves 22 for the first support shaft 61, the limiting shaft 62 and the second support shaft 63 to pass through; using the reinforcing plate 21 can improve the structural strength of the wheel support plate 2, thereby improving the load-bearing capacity and stability of the bracket; passing the first support shaft 61, the limiting shaft 62 and the second support shaft 63 through the reinforcing plate 21 can further improve the structural strength, load-bearing capacity and stability of the bracket.
[0030] Reference Figures 1 to 5 In this embodiment, the support arm 4 includes a support tube 41 and a support rod 42 passing through the support tube 41; a one-way locking structure or a two-way locking structure is provided between the support tube 41 and the support rod 42; the outer wheel limiting frame 3 can rotate around the second support shaft 63, and the support arm 4 provides support and limiting for the outer wheel limiting frame 3, restricting the rotation of the outer wheel limiting frame 3; specifically, in this embodiment, a one-way locking structure is provided between the support tube 41 and the support rod 42, so the outer wheel limiting frame 3 can rotate inward around the second support shaft 63, but cannot rotate outward, thereby ensuring the limiting effect on the wheel; in this embodiment, the support rod 42 is embedded in the support tube 41, which can improve the structural strength of the support arm 4, thereby improving the load-bearing capacity and stability of the bracket.
[0031] Reference Figures 1 to 5Specifically, the one-way locking structure includes a one-way rack 43 disposed on the side wall of the support rod 42, and a lock head 44 disposed on the support tube 41; an elastic element 45 is disposed between the lock head 44 and the support tube 41, and the elastic force of the elastic element 45 makes the lock head 44 tend to rotate to engage with the one-way rack 43; disposing the lock head 44 on the support tube 41 has the advantage of convenient operation.
[0032] Reference Figures 1 to 5 The inner wheel limiting frame 5 is mounted on the wheel support plate 2 and works in conjunction with the outer wheel limiting frame 3 to limit and fix a wheel, thereby improving vehicle stability. Specifically, the inner wheel limiting frame 5 includes a limiting base 51 and a limiting groove plate 52 rotatably connected to the limiting base 51. Preferably, the position of the limiting base 51 relative to the wheel support plate 2 is adjustable. The rotatable limiting groove plate 52 and the movable limiting base 51 can match wheels of different sizes, improving the applicability of the bracket and enhancing the stability of wheel limiting. Specifically, the limiting base 51 and the wheel support plate 2 are connected by a bolt and nut assembly. The wheel support plate 2 has multiple base mounting holes 23 arranged along its length. By passing bolts through different base mounting holes 23, the position of the limiting base 51 can be adjusted, making operation convenient.
