Description

Technical Field

[0001] This invention relates to the field of vehicle towing equipment technology, and more particularly to a motorcycle trailer frame. Background Technology

[0002] With the increasing popularity of motorcycle riding and outdoor activities, the demand for motorcycle towing is growing. Motorcycle trailer racks, as crucial devices for securing motorcycles to trailers or vehicles, facilitate transporting motorcycles to different locations. Their structural design and ease of operation directly impact transportation safety and user experience. Therefore, providing a stable, easy-to-operate, and reliable motorcycle trailer rack is of significant practical importance.

[0003] Currently, existing motorcycle trailer racks have many shortcomings in practical use. For example, the side panels of most trailer racks are fixed and cannot be folded or are inconvenient to fold, occupying a large space when not in use, which is not conducive to storage and transportation. In addition, the fixing devices can usually only lock a few parts of the motorcycle, making it difficult to adapt to the fixing requirements of different models or different parts, causing the motorcycle to easily shake or shift during transportation, affecting safety. On the other hand, there is a lack of effective speed control mechanisms between the relatively flippable parts of the trailer rack, which can easily cause impact due to excessive speed during flipping operations, posing a risk of collision with people or objects; at the same time, the flipping locking structure is often complicated to operate or has insufficient reliability, posing a safety hazard of accidental flipping.

[0004] Chinese patent CN220996232U discloses a motorcycle trailer that is easy to load and unload. It uses a hydraulic cylinder to drive the vehicle body to rise and fall, and a ramp to load and unload motorcycles. A movable locking plate and slot are used for locking. However, this device still has the following shortcomings: it lacks foldable side panel assemblies, requiring additional ramps or manual lifting when loading and unloading motorcycles, making loading and unloading operations extremely inconvenient; furthermore, the fixing frame and trailer frame are locked only by a single limiting pin, a simple locking method that is prone to loosening or even falling out due to vibrations caused by road bumps during transportation, resulting in insufficient locking reliability and a safety hazard of motorcycles slipping off.

[0005] Therefore, how to provide a motorcycle trailer frame that is compact, safe to operate, reliable in fixation, and has a controllable flipping process is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0041] Figure 7 This is an example diagram of the base component structure according to an embodiment of the present invention. Figure 8 This is a partial example diagram of a motorcycle trailer frame according to an embodiment of the present invention, as shown below. Figure 7 , Figure 8 As shown, the base assembly 2 includes a base 21, a locking member 22, and a trailer hitch 23. The base 21 has symmetrically arranged second rotating holes 211 and locking pin fixing holes 212 on both sides. A limiting block 213 is provided at the lower end of the base 21, which restricts the rotation range of the base 21 relative to the bracket assembly 1. The locking member 22 is located on one side of the base 21, and the trailer hitch 23 is connected to one end of the base 21.

[0042] The locking component 22 includes a connecting seat 221, a first fixing pin 222, and a sleeve 223. The sleeve 223 is mounted on the bracket 11, and the connecting seat 221 is mounted on the base 21. The first fixing pin 222 is connected to the connecting seat 221 via a rope. In practical applications, the insertion of the first fixing pin 222 into the sleeve 223 prevents the bracket assembly 1 from accidentally overturning relative to the base assembly 2. One end of the trailer hook 23 is connected to the base 21, and the other end can be converted from a square hole interface to a round hole interface to connect to a trailer, depending on the actual application.

[0043] Figure 9 This is an example diagram of the flipping mechanism structure according to an embodiment of the present invention, such as... Figure 9 As shown, in this embodiment, the flipping mechanism 5 includes a transmission block 51, a transmission rope 52, a rotating assembly 53, and a locking pin assembly 54. One end of the transmission block 51 is connected and fixed to the drive rod 14, and the other end of the transmission block 51 is connected and fixed to the transmission rope 52. The two ends of the transmission rope 52 are respectively connected to the transmission block 51 and the locking pin assembly 54. In practical applications, when the drive rod 14 rotates inward, it drives the transmission block 51 to flip outward. The transmission rope 52 then pulls the locking pin assembly 54, releasing the lock between the support assembly 1 and the base assembly 2. Pulling the handle 13 can realize the rotation of the support assembly 1 relative to the base assembly 2.

[0044] The application principle of this invention is as follows:

[0045] First, remove the third side plate 33 from the bracket assembly 1 (when the third side plate 33 is not in use, it can be fixed to the bracket assembly 1 by the fixing block 114 and the second fixing clip 131). Connect one end of the third side plate 33 to one end of the second side plate 32, so that the motorcycle can travel along the third side plate 33 to the first side plate 31 and the second side plate 32, and the motorcycle wheels are placed upright on the side plate assembly 3.

[0046] Then, the motorcycle foot pedals are placed on the fixing clamp 41 to lock them in place. Depending on the actual needs, the first fixing clamp 421 can be adjusted to any position on the handlebar 13, and the fixing strap 424 can be adjusted appropriately according to the shape and size of the fixed part (such as the motorcycle handlebars, frame, etc.), and tightened after passing around the appropriate position on the motorcycle.

[0047] The trailer hook 23 at one end of the base assembly 2 can be converted from a square hole interface to a round hole interface to connect to a trailer, depending on the actual application. When it is necessary to flip the trailer frame, the drive rod 14 is rotated inward, which drives the transmission block 51 to flip outward. The transmission rope 52 then pulls the locking pin assembly to release the lock between the bracket assembly 1 and the base assembly 2. Pulling the handle 13 allows the bracket assembly 1 to rotate relative to the base assembly 2. The rotating component 53 provides friction for rotation, allowing the bracket assembly 1 to rotate slowly at a controllable speed, preventing it from rotating too fast and colliding with people or objects. At the same time, the limiting block 213 at the lower end of the base 21 can limit the rotation range of the base 21 relative to the bracket assembly 1, preventing excessive flipping. When flipping is not required, the first fixing pin 222 is inserted into the sleeve 223 to prevent the bracket assembly 1 from accidentally flipping relative to the base assembly 2.

[0048] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
