Description

Technical Field

[0001] The utility model relates to a two-wheeled vehicle, in particular to a two-wheeled vehicle folding structure with a semi-enclosed storage frame. Background Art

[0002] With the acceleration of urbanization and the enhancement of environmental awareness, two-wheeled vehicles, especially two-wheeled electric vehicles and two-wheeled bicycles, are becoming more and more popular as convenient and environmentally friendly means of transportation. However, there are some problems in the structural design of traditional two-wheeled vehicles that cannot be ignored, which limits their convenience and flexibility in daily use.

[0003] The structural design of traditional two-wheeled vehicles is usually large in size. Due to the fixed structure of the frame, even if some models have a folding function, the folded body is still relatively large and difficult to carry and store. In addition, the existing folding design usually cannot effectively protect the components after folding. The wheels and frame are exposed and easily damaged, and it is very inconvenient to carry.

[0004] Traditional folding methods for two-wheeled vehicles are mostly to fold the middle of the frame or simply retract the handlebars and pedals. This folding method can only partially reduce the size of the vehicle body and cannot effectively protect the wheels and other key components. When it is necessary to carry or transport, the folded two-wheeled vehicle is still large in size, which makes it difficult to carry. In addition, the lack of an effective rolling support structure increases the burden on the user, and the seat is not easy to fold and store, resulting in a further increase in size.

[0005] In addition, after the traditional two-wheeled vehicle is folded, it is not convenient to place it in any position for support. It can only be placed against a wall or laid down, which is very inconvenient for storage. Moreover, due to its large size, it is easy to take up space in the trunk of the vehicle when placed in the trunk of the vehicle, which is not conducive to carrying. Utility Model Content

That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0036] like Figure 1 and Figure 2 As shown, a folding structure of a two-wheeled vehicle with a semi-enclosed storage frame of the utility model comprises two side panels 2, which are arranged side by side and form a receiving cavity 11 in the middle, and the two side panels 2 form a vehicle body. The two side panels 2 can have the same shape in this embodiment, and of course they can also be different. The two side panels 2 form a vehicle body with a receiving cavity 11 for storing a front wheel 3 and a rear wheel 1. The two side panels 2 can be arranged parallel to each other, and of course they can also be arranged to have a certain slope.

[0037] like Figure 1 and Figure 2 As shown, it also includes a rear wheel 1, which is installed behind the two side panels 2 and is used for rear rolling support of the entire vehicle body;

[0038] It also includes a front wheel 3, which is installed on a frame rod 4. The frame rod 4 is rotatably installed on the vehicle body away from the rear wheel 1. The front wheel 3 is used as a front rolling support. When the frame rod 4 is rotated, it is stored in the accommodating cavity 11. In this embodiment, the rear wheel 1 with a motor can be used as the driving part of the entire vehicle. Of course, it can also be chain-driven, etc. The utility model does not specifically describe the driving part of the vehicle.

[0039] The vehicle also includes a foldable handlebar 6, which is rotatably mounted on the top of the frame rod 4. When the frame rod 4 is rotated and stored, the foldable handlebar 6 is folded. Figure 2 and Figure 3 As shown, when folding is required, the handlebar 6 can also be folded, so that the lateral volume of the handlebar of the vehicle is greatly reduced, further reducing the overall volume and making it easier to carry;

[0040] The vehicle seat assembly comprises a seat cushion 7, a vehicle seat adapter plate 9 and an elastic support member 8, one end of the elastic support member 8 is connected to the seat cushion 7 by a latch 17, and the other end forms a rotating connecting sleeve 81, the rotating connecting sleeve 81 is rotatably mounted on the second connecting rod 14 on the vehicle body, one end of the vehicle seat adapter plate is rotatably connected to the third connecting rod 16 on the vehicle body, and the vehicle seat adapter plate is covered and mounted on the seat cushion 7 away from the side of the third connecting rod. When folding and storage is required, the latch 17 is pulled out, and the elastic support member is rotated along the rotating connecting sleeve at the bottom and folded and retracted between the two side panels, and then the vehicle seat adapter plate is closed, so that the vehicle seat adapter plate covers between the two side panels, completing the folding and storage.

[0041] The two side plates 2 are connected and fixed by a plurality of first connecting rods 10, and the seat assembly is rotatably mounted on one or more of the first connecting rods 10. Figure 4 As shown in FIG. 6 , a plurality of first connecting rods 10 are used to connect the two side panels 2 . A larger number of first connecting rods 10 are concentrated at the upper end of the side panel 2 , and as few first connecting rods 10 as possible are arranged at the bottom to ensure that the wheel can be accommodated in the accommodating cavity 11 .

[0042] Among them, Figure 3 As shown, a transverse fixing rod 12 is provided on the top of the frame rod 4, and a U-shaped groove 121 is respectively provided on the bottom of both sides of the transverse fixing rod 12, and a rotating head 61 is provided at the position of the handlebar 6 corresponding to the U-shaped groove 121, and the rotating head 61 is rotatably installed into the U-shaped groove 121, and a locking screw 62 is provided through the rotating head 61 and the transverse fixing rod 12. When the handlebar 6 needs to be folded, it is only necessary to loosen the locking screw 62, and then use the rotating head 61 to rotate relative to the transverse fixing rod 12 to complete the folding of the handlebar 6. After folding, the width of the entire handle is greatly reduced, and the folded handlebar 6 can be used as a towing piece to tow the entire folded vehicle.

[0043] Among them, a rolling support wheel is arranged on one side of the vehicle body close to the rear wheel, and a protruding bottom support point is formed on the vehicle body located on one side of the rolling support wheel. When the front wheel is folded and stored, the vehicle body is placed vertically, and the bottom support point 15, the rolling support wheel 13 and the rear wheel form a three-point support at the bottom of the vehicle body, such as Figure 7 As shown, it can be supported and placed at will without leaning on it.

[0044] like Figure 5 As shown, when it is necessary to carry, there is no need to carry, and the rolling support wheel 15 is used as the rear rolling support, and then the handlebar 6 is pulled by hand, so that the whole two-wheeled vehicle can be rolled and dragged, which is very convenient. Since the width of the rolling support wheel is large, it can be more stable when towing, and its width is greater than the width of the entire rear wheel, which is more suitable for towing.

[0045] In this embodiment, the two side panels 2 are made of aluminum plates or carbon fiber materials. If the two side panels 2 are made of carbon fiber materials, the weight of the vehicle body can be greatly reduced while ensuring the strength. Of course, aluminum plates can also be used, which can also have a lighter weight.

[0046] A rotating part 5 is provided in the middle of the frame rod 4, and the two sides of the rotating part 5 are rotatably connected to the two side panels 2. When folded, the rotating part 5 is used as a rotating member so that the front wheel 3 can be flipped into the accommodating cavity 11. A fixed shaft can be provided between the two side panels, and the rotating part is rotatably mounted on the fixed shaft. Figure 4 As shown, when the front wheel 3 is retracted, in conjunction with the outer contour of the two side panels 2, the rear wheel 1 serves as a tail support to achieve towing, and the retracted front wheel 3 can be well protected by the two side panels 2, so that the strength of the retracted assembly is greatly improved.

[0047] In this embodiment, in order to fix the frame rod 4 during use, the rotating part 5 is configured with a locking piece, and the rotating part 5 is locked on the two side plates 2 by the locking piece. The locking piece is a fixing screw or a locking buckle, and the specific locking method is not limited.

[0048] The utility model proposes a novel two-wheeled vehicle design, which adopts two side panels 2 to form a vehicle body, and forms a receiving cavity 11 in the middle, and the wheels can be retracted into the receiving cavity 11 after folding. Through this design, the vehicle frame itself can protect the retracted vehicle components, and the seat can also be rotated and folded to fit the vehicle body, so that the folded vehicle is more compact;

[0049] In addition, after the front wheels 3 are stored, the rolling support wheels are used as the rear rolling support, and the lifting handle is used as a lifting member to achieve towing and carrying of the vehicle, which greatly improves the portability and practicality of the vehicle.

[0050] The utility model not only solves the problem that the traditional two-wheeled vehicle is large in size and inconvenient to carry after being folded, but also provides a solution with stronger protection and more convenient carrying, which significantly improves the user experience and market competitiveness of the two-wheeled vehicle.

[0051] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
