[0025] As Figure 1As shown, the application provides a folding mechanism, which comprises a first rotating part 100, a second rotating part 200, a pedal 300, and a locking assembly 400. The first rotating part 100 and the second rotating part 200 are rotationally connected. The pedal 300 is rotationally arranged on the first rotating part 100. The locking assembly 400 comprises a pull rope 410 and a sliding rod 420. The sliding rod 420 is slidingly arranged in the first rotating part 100. One end of the pull rope 410 is fixedly connected with the pedal 300, and the other end of the pull rope 410 is fixedly connected with the sliding rod 420. When the pedal 300 is in a first position in a natural state, the sliding rod 420 is inserted into the second rotating part 200, so that the relative position of the first rotating part 100 and the second rotating part 200 is fixed. When the pedal 300 is stepped on and is in a second position, the pull rope 410 pulls the sliding rod 420, so that the sliding rod 420 is separated from the second rotating part 200, and then the first rotating part 100 and the second rotating part 200 can relatively rotate.

[0026] In an embodiment, the first rotating part 100 is a key component in the folding mechanism, which cooperates with the second rotating part 200 to realize the rotating function. The first rotating part 100 is also the installation base of the pedal 300. The first rotating part 100 can be a metal or plastic component with certain strength and shape, which can bear a certain force and ensure the smoothness of rotation. The second rotating part 200 cooperates with the first rotating part 100 to build the rotating pivot of the entire folding mechanism. The second rotating part 200 is internally provided with a structure matched with the sliding rod 420, which is used to cooperate with the sliding rod 420 to realize the locking or unlocking function in a specific state. The pedal 300 is a component operated by the user, which is convenient for the user to trigger the unlocking process of the folding mechanism through the foot action. The pedal 300 is rotationally arranged in the middle of the first rotating part 100. The surface of the pedal 300 is provided with anti-slip texture to increase the safety and stability when stepping on.

[0027] The locking assembly 400 comprises a pull rope 410 and a slide bar 420. The first rotating part 100 is provided with a first mounting groove 110 on the side close to the pedal 300. The first mounting groove 110 is horizontally arranged and has a shape matching that of the slide bar 420. The slide bar 420 is slidingly arranged in the first mounting groove 110. The pull rope 410 serves to transmit the movement force of the pedal 300. It is generally made of a rope material with certain strength and flexibility, such as a steel wire rope or a nylon rope. The slide bar 420 is directly cooperated with the second rotating part 200 to realize the locking. The slide bar 420 is slidingly arranged in the first rotating part 100 and is horizontally arranged. It is made of metal and has a proper length and diameter to ensure that the slide bar 420 can be accurately inserted into or separated from the second rotating part 200. When the pedal 300 is in a natural state, the slide bar 420 is inserted into the second rotating part 200 under the action of the related structure to prevent the relative rotation of the first rotating part 100 and the second rotating part 200 and ensure that the folding mechanism is in a stable locking state. When the pedal 300 is stepped on, the pull rope 410 is pulled to make the slide bar 420 separate from the second rotating part 200, so that the relative rotation of the first rotating part 100 and the second rotating part 200 is allowed, and the folding function is realized.

[0028] In summary, the design structure of the folding mechanism is relatively simple. The locking and unlocking of the first rotating part 100 and the second rotating part 200 are realized through the linkage of the pedal 300, the pull rope 410 and the slide bar 420. The operation is convenient. The user only needs to control the state of the folding mechanism through a simple stepping action without the aid of other complex tools or operation procedures, which saves time and effort.

[0029] As shown in Figure 2 , the second rotating part 200 comprises a fixed shaft 220. The fixed shaft 220 is rotatably arranged in the second rotating part 200. The first rotating part 100 is fixedly mounted on the fixed shaft 220.

[0030] In an embodiment, the fixed shaft 220 is cylindrical, the fixed shaft 220 is horizontally arranged, the second rotating part 200 includes two extension arms 210, the two extension arms 210 are symmetrically arranged on two sides of the second rotating part 200, the fixed shaft 220 is arranged between the two extension arms 210, and the fixed shaft 220 is rotationally assembled with the extension arms 210. The fixed shaft 220 is horizontally arranged and parallel to the slide rod 420. A second mounting groove 120 is arranged on the side of the first rotating part 100 away from the pedal 300, the shape of the second mounting groove 120 matches the shape of the fixed shaft 220, the first rotating part 100 is fixedly mounted with the fixed shaft 220 through the second mounting groove 120, and the fixed shaft 220 provides a stable shaft center for rotation of the first rotating part 100 relative to the second rotating part 200, so that the first rotating part 100 can rotate relative to the second rotating part 200 through the fixed shaft 220.

[0031] In summary, the rotation connection between the first rotating part 100 and the second rotating part 200 is more stable through the arrangement of the fixed shaft 220. As the rotation center, the fixed shaft 220 can bear a larger radial and axial force, effectively disperses the stress generated in the folding and unfolding process, and improves the carrying capacity of the entire folding mechanism.

[0032] As shown in Figure 2 The two groups of pull ropes 410 and slide rods 420 are arranged on the two sides of the pedal 300.

[0033] In an embodiment, the first mounting groove 110 is symmetrically arranged on the two sides of the pedal 300, the two groups of slide rods 420 are respectively arranged in the two first mounting grooves 110, and the two pull ropes 410 are also correspondingly arranged on the two sides of the pedal 300. One end of the pull rope 410 is fixedly connected with the pedal 300, and the other end of the pull rope 410 is fixedly connected with the end of the slide rod 420 close to the pedal 300. When the pedal 300 is stepped on, the pull ropes 410 on the two sides can be stressed at the same time, and the force is uniformly transmitted to the corresponding slide rods 420. The length and tension of the pull rope 410 need to be accurately designed according to the rotation range of the pedal 300, the stroke of the slide rod 420, and the mechanical requirements of the entire folding mechanism, so as to ensure that the pull ropes 410 on the two sides can effectively pull the slide rods 420 at the same time when the pedal 300 is actuated. The above-mentioned bilateral arrangement can avoid problems such as jamming, wear or incomplete unlocking caused by uneven unilateral stress, and improve the stability and reliability of the operation of the folding mechanism.

[0034] In summary, the bilateral arrangement of the pull ropes 410 and the slide rods 420 can significantly improve the stress uniformity and stability of the folding mechanism. Even if one side of the pull rope 410 or the slide rod 420 fails, the other side can still maintain the basic function of the mechanism to a certain extent,

[0035] As shown inFigure 3 As shown, the folding mechanism also includes a guide part 500, which is fixedly installed on the first rotating part 100. The guide part 500 includes a guide post 520, through which the pull rope 410 passes.

[0036] In one specific embodiment, the guide portion 500 includes a fixed plate 510 and guide posts 520. The fixed plate 510 is a rectangular plate and is vertically arranged. Two guide posts 520 are provided, horizontally spaced apart on the fixed plate 510. The guide posts 520 and the fixed plate 510 are integrally formed. Screws pass through the fixed plate 510 and the guide posts 520 to fix the guide portion 500 to the first rotating portion 100. The guide portion 500 is located below the pedal 300. The pull rope 410 passes through the guide post 520. The guide post 520 can guide and constrain the movement trajectory of the pull rope 410, so that the pull rope 410 can pull the slide rod 420 along the axial direction of the slide rod 420 to reduce the wear of the slide rod 420.

[0037] like Figure 3 As shown, the locking assembly 400 also includes a housing 430 and an elastic member 440. Both the elastic member 440 and the slide bar 420 are disposed within the housing 430. One end of the elastic member 440 abuts against the end of the housing 430, and the other end of the elastic member 440 abuts against the slide bar 420. When the pedal 300 is in its natural first position, the elastic member 440 is in a compressed state, and the elastic member 440 pushes the slide bar 420 into the second rotating part 200.

[0038] In one specific embodiment, the outer shell 430 serves as a housing for the elastic element 440 and the slide bar 420, providing them with a relatively enclosed and stable working environment. The shape of the outer shell 430 matches the shape of the first mounting groove 110, and the outer shell 430 is fixedly installed in the first mounting groove 110. The outer shell 430 is generally cylindrical, and an annular first abutment portion is provided on the side of the outer shell 430 near the pedal 300. The slide bar 420 is slidably disposed in the outer shell 430, and a second abutment portion is provided in the middle of the slide bar 420. In this embodiment, the elastic element 440 is a spring, sleeved on the slide rod 420, and located between the first and second contact parts 423. The elastic element 440 plays a crucial role in resetting and locking in this folding mechanism. When the pedal 300 is in its natural state, the elastic element 440 is compressed, and its stored elastic potential energy pushes the slide rod 420 into the second rotating part 200, locking the first and second rotating parts 100 and 200. When the pedal 300 is pressed, the pull rope 410 overcomes the elastic force of the elastic element 440, pulling the slide rod 420 away from the second rotating part 200. When the external force on the pedal 300 disappears, the elastic element 440 pushes the slide rod 420 back to its initial locked position, ensuring that the folding mechanism can automatically reset and maintain its locked state.

[0039] In summary, the elastic element 440 provides automatic locking and reset functions for the folding mechanism, making the folding mechanism more convenient to use. Users do not need to manually operate the slide bar 420 to reset it. They only need to release the pedal 300, and the elastic element 440 will automatically push the slide bar 420 back to the locked position, avoiding safety hazards caused by forgetting to lock it.

[0040] like Figure 2 As shown, the second rotating part 200 also includes a locking part 230, which includes a fixing hole 231. The fixing hole 231 is provided on the second rotating part 200, and the position of the fixing hole 231 corresponds to that of the slide rod 420 so that the slide rod 420 can be inserted into the fixing hole 231.

[0041] In one specific embodiment, the locking part 230 is a key component in the folding mechanism for achieving precise locking of the first rotating part 100 and the second rotating part 200. The fixing holes 231 in the locking part 230 are symmetrically arranged on the two side extension arms 210 of the second rotating part 200, and the position and size of the fixing holes 231 are closely matched with the slide bar 420, ensuring that when the pedal 300 is in its natural state, the slide bar 420 can be accurately inserted into the fixing holes 231, thus achieving reliable locking of the first rotating part 100 and the second rotating part 200.

[0042] like Figure 2As shown, the locking portion 230 further comprises a sleeve 232 fixedly installed in the fixing hole 231, and the sleeve 232 is shaped to match the shape of the slide rod 420 so that the slide rod 420 can be inserted into the sleeve 232.

[0043] In a specific embodiment, the sleeve 232 serves as an inner lining component of the fixing hole 231, further optimizing the cooperation between the slide rod 420 and the locking portion 230. The sleeve 232 is shaped to match the slide rod 420, and the inner diameter of the sleeve 232 is slightly larger than the diameter of the slide rod 420. The sleeve 232 is usually made of metal material, which has high hardness and wear resistance. The sleeve 232 is fixedly installed in the fixing hole 231 to ensure that the sleeve 232 does not loosen or displace during use. The inner wall of the sleeve 232 can be specially treated, such as polishing or chrome plating, to reduce the frictional resistance when the slide rod 420 is inserted and pulled out. During the operation of the folding mechanism, after the slide rod 420 is inserted into the sleeve 232, the sleeve 232 can provide good guidance and support for the slide rod 420, making the movement of the slide rod 420 more smooth during locking and unlocking, and further improving the operation performance of the folding mechanism.

[0044] In summary, the addition of the sleeve 232 significantly improves the cooperation effect between the slide rod 420 and the locking portion 230. On the one hand, the sleeve 232 reduces the wear caused by the direct contact between the slide rod 420 and the fixing hole 231, prolonging the service life of the slide rod 420 and the fixing hole 231. On the other hand, the precise guiding effect of the sleeve 232 makes the slide rod 420 more stable and accurate during insertion and pulling out, reducing the risk of locking failure or unlocking difficulty caused by the deviation or jamming of the slide rod 420.

[0045] As shown, Figure 3 The slide rod 420 comprises a first slide rod 421 and a second slide rod 422, and the first slide rod 421 and the second slide rod 422 are concentrically arranged. The diameter of the first slide rod 421 is smaller than the diameter of the second slide rod 422, and the elastic member 440 is sleeved on the first slide rod 421.

[0046] In a specific embodiment, the first slide rod 421 and the second slide rod 422 are both cylindrical, and the first slide rod 421 and the second slide rod 422 are integrally formed. The first slide rod 421 is located on the side of the second slide rod 422 close to the pedal 300. The first slide rod 421 and the second slide rod 422 are concentrically arranged, and the diameter of the first slide rod 421 is smaller than the diameter of the second slide rod 422, so that a second abutting portion 423 is formed at the connection between the first slide rod 421 and the second slide rod 422. Thus, the elastic member 440 sleeved on the first slide rod 421 can contact the second abutting portion 423 to push the slide rod 420 to move.

[0047] In order to achieve the purpose of the utility model, in one embodiment, the application further provides a scooter, the scooter comprising the folding mechanism, the handle part of the scooter is installed through the folding mechanism, so that the handle part of the scooter can be conveniently folded and unfolded, and the storage of the scooter is facilitated.

[0048] The above are only the preferred embodiments of the application, and do not limit the patent scope of the application, and any equivalent structure or equivalent process transformation using the content of the specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the application.
