Description

Technical Field

[0001] This utility model belongs to the field of motorcycle parts technology, and in particular relates to a motorcycle rear rack. Background Technology

[0002] As a convenient means of transportation, the rear rack of a motorcycle is an important functional component for users to carry luggage and goods, especially indispensable for long-distance riding or daily transportation. Its expandability and functionality directly affect the user experience.

[0003] For example, Chinese utility model patent publication number CN216424634U discloses a motorcycle rear rack that increases the carrying area by inserting an extension bracket. However, the extension bracket is rigidly connected to the main body, making it impossible to quickly disassemble and assemble, and it lacks an independent storage unit design.

[0004] Therefore, there is an urgent need for a motorcycle rear rack with a detachable storage unit and a highly reliable locking structure. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a motorcycle rear rack.

[0006] The objective of this utility model can be achieved through the following technical solution: A motorcycle rear rack includes a main frame, a storage frame detachably connected to the rear end of the main frame, a plug-in part at the front end of the storage frame, a connecting component fixed on the main frame to cooperate with the plug-in part, the connecting component including a support rod fixed to the surface of the main frame, a plug-in rod extending horizontally from the end of the support rod, a support plate vertically sleeved and fixed on the plug-in rod, and a locking nut threaded to the plug-in rod for pressing the side wall of the storage frame, a first limiting hole for the plug-in rod to be inserted on the plug-in part at the front end of the storage frame, a load-bearing bracket at the bottom of the storage frame, the load-bearing bracket including a vertical plate and a horizontal support plate extending horizontally from the vertical plate and supporting the bottom of the storage frame, the vertical plate being sleeved and fixed on the plug-in rod and clamped and fixed by the support rod and the support plate.

[0007] Preferably, the bottom of the support plate is also provided with an anti-detachment limiting component, which includes a V-shaped bracket fixed to the bottom of the support plate and a limiting pin at the end of the V-shaped bracket. The front end of the storage frame is provided with a second limiting hole for the limiting pin to be inserted.

[0008] Preferably, the surface of the support plate is fitted with a reflective strip, which is made of glass microsphere-type reflective material with a thickness of 0.1mm-0.5mm.

[0009] Preferably, the storage box has two symmetrically arranged suspension hooks at its rear end.

[0010] Preferably, the limiting pin and the insertion rod are arranged in parallel vertically, and the central axis of the limiting pin is perpendicular to the insertion rod.

[0011] Preferably, the surface of the V-shaped bracket is in contact with the vertical plate.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. Adopting a detachable modular design, the storage frame can be quickly assembled and disassembled through the cooperation of the plug-in rod and the locking nut, solving the problem that traditional rear racks cannot flexibly expand storage space. The vertical plate of the load-bearing bracket is sleeved and fixed on the plug-in rod to form a rigid force transmission chain. Combined with the direct support of the bottom horizontal support plate, the load is effectively distributed, avoiding the risk of fracture caused by the concentrated force of traditional cantilever structures, while reducing structural redundancy to optimize space utilization.

[0014] 2. The V-shaped bracket at the bottom of the support plate and the limiting pin form a double-point constraint at the top and bottom. Even if the locking nut is accidentally loosened, it can still prevent the storage frame from falling off. The elastic deformation of the V-shaped bracket can also absorb the energy of bumps.

[0015] 3. The glass microbead reflective strip embedded on the surface of the support panel solves the problem of easy aging and falling off of traditional adhesive reflective strips. It can significantly improve the visibility of the rear in low light conditions and enhance driving safety.

[0016] 4. The symmetrical suspension hooks at the rear of the storage box expand the suspension function, and the symmetrical layout of the double hooks can counteract the eccentric moment and prevent tipping. The overall structure has achieved effective improvement in functionality, reliability and safety. Attached Figure Description

Detailed Implementation

[0022] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0023] like Figures 1-4 As shown, this embodiment provides a motorcycle rear rack, including a main frame 1. A storage frame 4 is detachably connected to the rear end of the main frame 1. The storage frame 4 has a plug-in part at its front end. A connecting component 2 that mates with the plug-in part is fixed on the main frame 1. The connecting component 2 includes a support rod 21 fixed to the surface of the main frame 1, a plug-in rod 26 extending horizontally from the end of the support rod 21, a support plate 24 vertically sleeved and fixed on the plug-in rod 26, and a locking nut 22 threadedly connected to the plug-in rod 26 for pressing the side wall of the storage frame 4. The plug-in part at the front end of the storage frame 4 is provided with a first limiting hole 41 for the plug-in rod 26 to be inserted. A load-bearing bracket 3 is provided at the bottom of the storage frame 4. The load-bearing bracket 3 includes a vertical plate 31 and a horizontal support plate 32 extending horizontally from the vertical plate 31 and supporting the bottom of the storage frame 4. The vertical plate 31 is sleeved and fixed on the plug-in rod 26 and clamped and fixed by the support rod 21 and the support plate 24.

[0024] The working principle of the rear rack of this motorcycle in practical applications is as follows:

[0025] During assembly, firstly, the vertical plate 31 of the load-bearing bracket 3 is fitted onto the plug-in rod 26, and then the support plate 24 is vertically fitted and fixed onto the plug-in rod 26. Next, the plug-in part at the front end of the storage frame 4 is aligned with the connecting component 2, so that the plug-in rod 26 is inserted into the first limiting hole 41, and at the same time, the limiting pin 23 of the anti-detachment limiting component is inserted into the second limiting hole 42. Tighten the locking nut 22, push the side wall of the storage frame 4 to fit tightly with the support plate 24, and achieve lateral compression. The horizontal support plate 32 of the load-bearing bracket 3 automatically supports the bottom of the storage frame 4, and together with the plug-in rod 26, it bears the vertical load.

[0026] The storage frame 4 adopts a detachable modular design. Through the cooperation of the plug-in rod 26 and the locking nut 22, the storage frame 4 can be quickly assembled and disassembled, solving the problem that the tail frame cannot flexibly expand the storage space after traditional welding or bolt fixing. The vertical plate 31 of the load-bearing bracket 3 is directly sleeved and fixed on the plug-in rod 26 to form a rigid force transmission chain, avoiding the risk of breakage caused by the concentration of stress points in traditional cantilever expansion frames. The bottom of the storage frame 4 is directly supported by the horizontal support plate 32, without the need for an additional support frame, reducing structural redundancy and optimizing space utilization.

[0027] Furthermore, such as Figure 3 As shown, in this embodiment, the bottom of the support plate 24 is also provided with an anti-detachment limiting component. The anti-detachment limiting component includes a V-shaped bracket 27 fixed to the bottom of the support plate 24 and a limiting pin 23 provided at the end of the V-shaped bracket 27. The front end of the storage frame 4 is provided with a second limiting hole 42 for the limiting pin 23 to be inserted.

[0028] The limiting pin 23 of the V-shaped bracket 27 and the plug rod 26 form a double-point constraint at the top and bottom. Even if the locking nut 22 is accidentally loosened, the storage box 4 is still restricted in its displacement by the limiting pin 23 to prevent it from falling off completely. The elastic deformation of the V-shaped bracket 27 can absorb the energy of road bumps.

[0029] Furthermore, the surface of the support plate 24 is embedded with a reflective strip 25, which is made of glass microsphere-type reflective material with a thickness of 0.1mm-0.5mm.

[0030] The glass microsphere reflective strip 25 is directly embedded in the supporting plate 24, eliminating the need for external reflective sheets and solving the problem of easy aging and detachment of traditional adhesive reflective strips. A thickness range of 0.1mm-0.5mm ensures a reflective efficiency >300cd / lx / m². 2 In low-light environments, the recognition distance is increased to over 150 meters. In dimly lit environments (such as at night or inside tunnels), it can reflect surrounding light sources (such as the lights of other vehicles), improving the visibility of the motorcycle's rear end, warning vehicles behind, reducing the risk of rear-end collisions, and enhancing driving safety.

[0031] Furthermore, the storage frame 4 is symmetrically provided with two suspension hooks 33 at its rear end.

[0032] The symmetrical suspension hooks 33 extend the suspension function of helmets, backpacks, etc., and prevent users from adding extra hooks that would damage the structural integrity; the symmetrical double hook layout counteracts the eccentric moment of suspension on one side and prevents the storage box 4 from tipping over.

[0033] Furthermore, the limiting pin 23 and the insertion rod 26 are arranged in parallel vertically, and the central axis of the limiting pin 23 is perpendicular to the insertion rod 26.

[0034] The vertical distribution of the limiting pin 23 and the plug rod 26 forms a couple resistance structure, which suppresses the torsional deformation of the storage frame 4 when turning and effectively improves the torsional stiffness.

[0035] The surface of the V-shaped bracket 27 is in contact with the vertical plate 31.

[0036] The contact surface between the V-shaped bracket 27 and the vertical plate 31 forms an auxiliary force transmission path, dispersing the impact load of the storage frame 4 to the main frame 1 and reducing the peak shear stress of the plug rod 26.

[0037] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
