Description

Technical Field

[0001] This utility model belongs to the field of folding vehicles, and in particular relates to a folding structure and a vehicle having the structure. Background Technology

[0002] Currently, due to the limited size of two-wheeled vehicles, they are inconvenient to carry and transport. Applying folding mechanisms can effectively reduce vehicle size, making them easier to carry and transport. However, existing folding structures have many problems during use, such as protruding structural components, insufficient connection reliability, inconvenient folding operation, and complex structure.

[0003] Existing technologies include: Chinese Patent CN105292358B, published on February 3, 2016, which discloses "a folding handle, mainly composed of a connecting crossbar installed on the upper part of a telescopic rod and a pair of handles connected to both ends of the connecting crossbar. The characteristic feature is that a handle folding device is provided between the handles and the connecting crossbar. The handle folding device mainly consists of a movable part, a pin, a spring, a folding rotation shaft, and a spring button switch. Because of the handle folding device, when the user presses the spring button switch, the movable part, along with the handles, can be easily pulled outward from the connecting crossbar and folded downward at 90° to be housed on both sides of the frame telescopic rod. This achieves the effect of quick handle folding and space saving. Furthermore, the locking mechanism is very secure after the handle is unfolded, thus solving the problem of insufficient fixation when the handle is unfolded in existing technologies. In addition, this utility model has the advantages of simple structure and convenient and quick handle folding and unfolding processes."

[0004] However, this utility model has the following problems:

[0005] During the folding process, one hand needs to press the button to disengage the moving part from the switch lock. When released, it will return to its original position under the action of the spring. That is, you need to keep pressing during the folding process. At the same time, the other hand needs to overcome the elastic force of the spring and pull the handle towards the handle side. At this time, both hands can only operate the folding on one side at a time.

[0006] In summary, a folding structure and a vehicle incorporating this structure are proposed, which allows for the unfolding or folding of a single-sided bent component with one hand. The structure is simple, the operation is easier, and the unfolded or folded state is more stable. Utility Model Content

[0007] In view of this, the present invention aims to propose a folding structure and a vehicle having the structure, mainly to solve the problem that existing folding structures require both hands to operate simultaneously to fold and store the vehicle.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: According to one aspect of the present invention, a folding structure is provided, comprising:

[0009] The fixed component has at least one end pivotally connected to the bent component;

[0010] A limiting component is fitted onto the outer wall of the bending component;

[0011] An elastic component is connected at one end to a limiting component and at the other end to a bending component. When the elastic component is unfolded, it pushes the distal end of the limiting component to fit onto the corresponding end of the fixed component, locking the relative positions of the fixed component and the bending component. When the elastic component is compressed, the relative position locking is released.

[0012] Furthermore, the limiting component has a locking part at one end near the fixing component, and the fixing component has a mating part at one end near the limiting component, and the locking part is used to couple with the mating part.

[0013] Furthermore, the locking part has an internal thread, and the mating part has an external thread.

[0014] Furthermore, the locking part is a groove, and the mating part is a protrusion that mates with the groove.

[0015] Furthermore, the end of the fixing component is provided with a baffle to restrict the bending component and the fixing component from rotating within 90 degrees.

[0016] Furthermore, the fixing component and the limiting component are pivotally connected by a connecting component.

[0017] Furthermore, the connecting component is a pin.

[0018] Furthermore, a friction-reducing component is fitted onto the outer wall of the connecting component, with one side of the friction-reducing component connected to the fixing component and the other side connected to the bending component.

[0019] Furthermore, there are two friction-reducing components, symmetrically distributed on both sides of the bending assembly.

[0020] According to another aspect of the present invention, a vehicle is provided, including the aforementioned folding structure.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. This folding structure unlocks the device by pushing the limiting component with one hand and compressing the elastic component, and then bends the bending component in this state to achieve quick folding with one hand.

[0023] 2. This folding mechanism locks the unfolded state by pressing the limiting component with the elastic component. When the bending component is subjected to forces in different directions, the limiting component will not be unlocked, thus achieving a stable locking state.

[0024] 3. In this folding mechanism, the limiting component is set on the outside of the bending component and the fixing component. When the hand moves the limiting component, it can control and reduce the contact between the limiting component and the bending component and the fixing component, reduce the friction caused by the uneven force on the limiting component and the relative angle change of the bending component and the fixing component, and realize smooth and fast folding and unfolding.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present utility model can be combined with each other, and the described embodiments are only some embodiments of the present utility model, not all embodiments.

[0033] It should be noted that the descriptions of "left," "right," "left side," "right side," "upper part," "lower part," "top," and "bottom" in this utility model are defined based on the orientation or positional relationships shown in the accompanying drawings. They are used solely for the convenience of describing this utility model and for simplifying the description, and are not intended to indicate or imply that the described structure must be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0034] In the description of this utility model, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] Referring to the accompanying drawings, this embodiment provides a folding structure according to one aspect of the present invention, comprising:

[0036] The fixing component 3 has at least one end pivotally connected to the bending component 1; the fixing component 3 may have multiple connecting ends, and in this embodiment, it is preferred that both ends are rotatably connected to the bending component 1.

[0037] A limiting component 2 is fitted onto the outer wall of the bending component 1. The limiting component 2 is slidably connected to the folding tube 1-1 of the bending component 1. The folding tube 1-1 can be hollow to reduce weight. A connecting post 1-2 is provided at the end of the folding tube 1-1, which is rotatably connected to the fixing component 3. A positioning pin 1-3 is provided between the connecting post 1-2 and the folding tube 1-1 to prevent loosening. By positioning the limiting component 2 on the outside of the bending component 1 and the fixing component 3, the hand can control and reduce contact with the bending and fixing components when moving the limiting component 2. This reduces the angular changes relative to the bending and fixing components caused by uneven force on the limiting component, thereby reducing unnecessary friction and achieving stable and rapid folding.

[0038] The elastic component 4 is connected at one end to the limiting component 2 and at the other end to the bending component 1. When the elastic component 4 is unfolded, it pushes the distal end of the limiting component 2 onto the corresponding end of the fixing component 3, locking the relative position of the fixing component 3 and the bending component 1. When the elastic component 4 is compressed, the relative position lock is released. In this embodiment, the elastic component 4 is preferably a spring, which is sleeved on the connecting post 1-2. One end contacts the folding tube 1-1, and the other end contacts the protrusion provided on the inner side of the limiting component 2. The spring pushes the limiting component 2 onto the fixing component 3 to achieve locking. This is beneficial because when the folding tube 1-1 is subjected to forces in different directions, the folding tube 1-1 tends to change angle relative to the limiting component, and a force is generated at the contact point. However, since the limiting component is sleeved on the folding tube 1-1 and the fixing component 3, and the spring presses against the limiting component 2, the limiting component 2 will not move along the axial direction, thus preventing the limiting component from unlocking and achieving a stable locking state. By pushing the limiting component 2 with one hand and compressing the elastic component 4, the unlocked state is achieved. In this state, the bending component can be bent to achieve quick folding with one hand.

[0039] In this embodiment, the limiting component 2 has a locking part near the fixing component 3, and the fixing component 3 has a mating part near the limiting component 2. The locking part is used to couple with the mating part. The locking part and mating part make the locking state of the limiting component 2 more stable. When the folding tube 1-1, the limiting component 2, and the fixing component 3 are cylindrical, this reduces the rotation of the limiting component 2 in the locking position, thus improving the grip feel.

[0040] In this embodiment, the locking part is a groove, and the mating part is a protrusion that mates with the groove. Both the groove and the protrusion are axially arranged to reduce the rotation of the limiting component 2.

[0041] In this embodiment, a baffle is provided at the end of the fixing component 3 to restrict the bending component 1 and the fixing component 3 from rotating within 90 degrees. Restricting the rotation range of the bending component 1 and the fixing component 3 can control the folding direction, making the folding direction singular and facilitating quick folding and storage; without directional restriction, in actual use, the folding direction may be incorrect, requiring refolding in the opposite direction, which affects the folding and storage effect.

[0042] In this embodiment, the fixing component 3 and the limiting component 2 are pivotally connected by the connecting component 5. The detachable and replaceable connecting component 5 helps reduce future replacement and maintenance costs.

[0043] In this embodiment, the connecting component 5 is a pin 5-1. Screws 5-2 are provided at both ends of the pin to limit the pin 5-1.

[0044] In this embodiment, a friction-reducing component 5-3 is fitted onto the outer wall of the connecting component 5. One side of the friction-reducing component 5-3 is connected to the fixing component 3, and the other side is connected to the bending component 1. The friction-reducing component 5-3 is made of nylon or other wear-resistant materials, which can reduce the relative sway between the connecting column 1-2 and the fixing component 3, make the folding and unfolding process smoother, and increase the service life of the fixing component 3 and the bending component 1.

[0045] In this embodiment, there are two friction-reducing components 5-3, which are symmetrically distributed on both sides of the bending assembly 1.

[0046] According to one aspect of this utility model, a vehicle is provided, including the aforementioned folding structure. The connection between the folding structure and the vehicle can be designed accordingly based on actual needs, so that the vehicle, after having the corresponding structure, possesses the same functions.

[0047] The working principle of the two states during use;

[0048] In the unfolded state, simply rotate the bending component 1 to achieve a coaxial position with the fixed component 3. At this time, under the action of the spring, the spring pushes the limiting component 2 to move towards the fixed component 3 and finally fits onto the fixed component 3. This achieves coaxial fixation between the bending component 1 and the fixed component 3, thus reaching the extended state.

[0049] Since a baffle is provided on the fixed component 3, it is only necessary to rotate the bending component 1 to contact the baffle. At this time, the bending component 1 and the fixed component 3 are coaxial. The spring pushes the limiting component 2 to contact the fixed component 3 and is sleeved on the fixed component 3, thus achieving the extended state.

[0050] In the folded state, simply push the limiting component 2 with one hand to press the locking spring, and the limiting component 2 will disengage from the fixing component 3. In this state, bend the bending component 1 to achieve folding and storage.

[0051] Because a baffle is set on the fixed component 3, the relative rotation direction of the bending component 1 is limited, and the problem of incorrect folding direction will not occur during the folding process. Specific implementation method 2:

[0053] The only difference between this specific embodiment and Specific Embodiment 1 is that the locking part is an internal thread and the mating part is an external thread.

[0054] The working principle of this embodiment is as follows: when unfolded, the limiting component 2 needs to rotate due to the threads in order to connect with the fixing component 3. When folded, it rotates in the opposite direction. The advantage of this method is that the connection between the limiting component 2 and the fixing component 3 is more stable through the threaded connection, the movable gap is smaller, and the user experience is better.

[0055] The embodiments of the present invention disclosed above are merely illustrative of the present invention. The embodiments do not exhaustively describe all details, nor do they limit the present invention to the specific implementations described. Many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to better understand and utilize the present invention.
