[0046] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0047] In this embodiment of the application, the axial direction of the horizontal tube 100 is the x-axis shown in the figure, the radial direction of the horizontal tube 100 is the y-axis shown in the figure, and the vertical direction is the z-axis shown in the figure.

[0048] refer to Figure 1 and Figure 2 The folding handlebars provided in this application embodiment include: a horizontal tube 100 and two handlebars 200. The horizontal tube 100 has openings at both ends along its axial direction. The connecting segments 201 of the two handlebars 200 extend into the two ends of the horizontal tube 100 from the openings and are slidably connected to the two ends of the horizontal tube 100 along the axial direction (x-axis shown in the figure).

[0049] A first connector 400 is fixedly installed on the connecting section 201.

[0050] A second connector 500 is slidably connected inside the horizontal tube 100. The second connector 500 can slide inside the horizontal tube 100 along the axial direction (x-axis shown in the figure).

[0051] The second connector 500 is rotatably connected to the first connector 400 via a pivot 600, which is perpendicular to the axial direction (x-axis shown in the figure) of the horizontal tube 100. Since the second connector 500 is located inside the horizontal tube 100, the horizontal tube 100 restricts the second connector 500 from rotating around the pivot 600. When the first connector 400 is located inside the horizontal tube 100, it is also restricted by the horizontal tube 100 and cannot rotate around the pivot 600. However, when the first connector 400 is located outside the horizontal tube 100, the restriction of the horizontal tube 100 on the first connector 400 is lifted, and the first connector 400 can rotate around the pivot 600.

[0052] The second connector 500 can slide within the horizontal tube 100 along the axial direction (x-axis shown in the figure) between a first position and a second position, the first position being close to the center of the horizontal tube 100 and the second position being close to the end opening of the horizontal tube 100.

[0053] Continue to refer to Figure 1 and Figure 2 When the handlebars 200 are in use, the second connector 500 slides to the first position along the axial direction (x-axis shown in the figure) of the cross tube 100. The first connector 400 and the connecting section 201 are both located inside the cross tube 100. That is to say, as the turning point of the folding handlebars, the rotational connection between the second connector 500 and the first connector 400 is located inside the cross tube 100. The rotation of the first connector 400 around the pivot 600 is restricted. The user does not experience any force at the turning point during riding, which greatly increases the user's riding safety.

[0054] Meanwhile, the second connector 500, the first connector 400, and the connecting section 201 are all located inside the horizontal tube 100, which improves the structural strength of the folding handlebars and can prevent the handlebars from shaking when encountering bumpy roads during riding.

[0055] refer to Figure 5 and Figure 6 When the handlebar 200 is in the folded state, the second connector 500 slides to the second position along the axial direction (x-axis shown in the figure) of the cross tube 100. The first connector 400 and the connecting section 201 are both located outside the cross tube 100. That is to say, as the turning point of the folding handlebar: the rotating connection between the second connector 500 and the first connector 400 is located outside the cross tube 100, the restriction of the cross tube 100 on the first connector 400 is released, and the first connector 400 can rotate around the pivot 600.

[0056] The folding mechanism composed of the second connector 500 and the first connector 400 has a simple structure, small size and low cost. It can achieve the folding of the handlebars through a simple mechanical connection and can also avoid taking up too much handlebar space.

[0057] refer to Figure 2 Fasteners 300 are provided at both ends of the horizontal tube 100 along its axial direction (x-axis shown in the figure). The fasteners 300 are used to limit the sliding of the connecting section 201.

[0058] When the handlebar 200 is in use, the fastener 300 can lock the connecting section 201, ensuring that the handlebar 200 can no longer slide along the axial direction (x-axis shown in the figure) of the cross tube 100, preventing the handlebar 200 from sliding out of the cross tube 100 when in use, thus improving the structural stability of the folding handlebar and further increasing the safety of the user's riding.

[0059] When the handlebars 200 need to be folded, the fasteners 300 are released from locking the connecting section 201, allowing the handlebars 200 to slide out of the cross tube 100 along the axial direction (x-axis shown in the figure).

[0060] In this embodiment, the horizontal tube 100 is provided with fastening holes at both ends along its axial direction (x-axis shown in the figure), and the fastening holes are through holes; the fastener 300 is connected to the fastening hole, and the end of the fastener 300 extends into the horizontal tube 100 through the fastening hole, so that the end of the fastener 300 protrudes from the inner peripheral wall of the horizontal tube 100.

[0061] When the connecting segment 201 is located inside the horizontal tube 100, and there is a gap between the end of the fastener 300 and the outer peripheral wall of the connecting segment 201 along the radial direction of the horizontal tube 100 (y-axis shown in the figure), the fastener 300 releases the locking of the connecting segment 201, and the connecting segment 201 can slide.

[0062] When the connecting segment 201 is located inside the horizontal tube 100, and along the radial direction of the horizontal tube 100 (y-axis shown in the figure), when the end of the fastener 300 abuts against the outer peripheral wall of the connecting segment 201, the fastener 300 can lock the connecting segment 201, and the connecting segment 201 cannot slide.

[0063] refer to Figure 3 and Figure 4 The outer peripheral wall of the second connector 500 is provided with a limiting protrusion 501, and the inner peripheral wall of the horizontal tube 100 is provided with a limiting groove 101 that is adapted to the limiting protrusion 501. The limiting protrusion 501 is slidably connected in the limiting groove 101.

[0064] The sliding connection between the limiting protrusion 501 and the limiting groove 101 can limit the second connector 500, preventing the second connector 500 from rotating around the axis (x-axis shown in the figure) of the horizontal tube 100, thereby improving the structural stability of the folding mechanism composed of the second connector 500 and the first connector 400.

[0065] refer to Figure 7 The second position is close to the end opening of the horizontal tube 100, and the fastener 300 is disposed at the end of the horizontal tube 100; when the second connector 500 slides to the second position, the second connector 500 is close to the fastener 300, and at this time the first end face of the limiting protrusion 501 abuts against the end of the fastener 300.

[0066] The end of the fastener 300 can restrict the limiting protrusion 501 in the axial direction (x-axis shown in the figure) of the horizontal tube 100, thereby preventing the second connector 500 from sliding out of the horizontal tube 100.

[0067] In other words, the fastener 300 can not only lock the connecting section 201, but also limit the sliding of the second connector 500; multiple effects can be achieved with one component, without the need to introduce other components, reducing costs and further reducing the volume of the folding mechanism composed of the second connector 500 and the first connector 400.

[0068] refer to Figures 1-4 In this embodiment of the application, both openings of the horizontal tube 100 along its axial direction are retractable; a clamping kit 700 is respectively fitted around the outer periphery of the two openings. The clamping kit 700 is a C-shaped hoop. The opening end of the C-shaped hoop has two connecting ears 702 spaced apart along its circumference. Each of the two connecting ears 702 is provided with a fixing hole. The fixing member 701 is connected to both fixing holes, and the fixing member 701 can tighten the opening end of the C-shaped hoop so that the clamping kit 700 is tightened.

[0069] When the clamp kit 700 is tightened, the opening shrinks, and the shrinking opening can clamp the connecting section 201, so that the outer peripheral wall of the connecting section 201 abuts against the inner peripheral wall of the horizontal tube 100.

[0070] The clamp kit 700 is used to limit the sliding of the connecting section 201 when the handlebar 200 is in use, preventing the handlebar 200 from sliding out of the cross tube 100 when in use, thus improving the structural stability of the folding handlebar and further increasing the user's riding safety.

[0071] When the handlebars 200 need to be folded, the fastener 701 is disconnected from the two fixing holes so that the clamp kit 700 is released and the handlebars 200 can slide out of the cross tube 100 along the axial direction (x-axis shown in the figure).

[0072] Meanwhile, the clamp kit 700 is also provided with a connection hole, that is, the C-shaped clamp body is provided with a connection hole, the connection hole corresponds to the fastening hole provided at the end of the horizontal tube 100, and the fastener 300 is connected to both the connection hole and the fastening hole.

[0073] Fastener 300 can fix clamp kit 700 to horizontal tube 100, preventing clamp kit 700 from coming off horizontal tube 100 when it is loosened, or preventing clamp kit 700 from sliding from opening of horizontal tube 100 to other positions of horizontal tube 100 when it is loosened, thereby improving the connection stability of clamp kit 700.

[0074] refer to Figure 4 and Figure 8 In this embodiment of the application, both ends of the horizontal tube 100 along its axial direction (x-axis shown in the figure) are provided with through grooves 102. The inner wall surface of the through groove 102 along the axial direction of the horizontal tube 100 coincides with the opening so that the opening can be contracted.

[0075] Users can also observe the sliding of the internal components of the horizontal tube 100 through the through groove 102.

[0076] refer to Figure 2 and Figure 3 In this embodiment of the application, a limiting member 800 is provided on the inner peripheral wall of the horizontal tube 100, and the limiting member 800 is provided close to the first position; when the second connecting member 500 slides to the first position along the axial direction (x-axis shown in the figure) of the horizontal tube 100, the second end face of the limiting protrusion 501 abuts against the limiting member 800, and the second end face and the first end face are opposite to each other along the axial direction of the horizontal tube 100.

[0077] The limiting member 800 can restrict the second connector 500 in the axial direction (x-axis shown in the figure) of the horizontal tube 100 and provide an endpoint for the sliding of the second connector 500, thereby providing the user with a signal that the second connector 500 has slid into place.

[0078] refer to Figure 3 , Figure 7 , Figure 8 and Figure 9 In this embodiment of the application, the folding handlebars also include: an elastic element 901 and a rotating block 902.

[0079] The second connector 500 includes a connector body 502, which has a mounting groove 5021. The opening of the mounting groove 5021 is opposite to the bottom of the groove along the axial direction (x-axis shown in the figure) of the horizontal tube 100. The elastic element 901 and the rotating block 902 are both disposed in the mounting groove 5021.

[0080] The two ends of the elastic element 901 along its elastic extension direction are fixedly connected to the bottom of the mounting groove 5021 and the rotating block 902, respectively. The rotating block 902 is provided with a connecting protrusion 9021 at the end away from the elastic element 901. The connecting protrusion 9021 extends out of the mounting groove 5021 from the opening of the mounting groove 5021.

[0081] The connecting body 502 is also provided with a rotating connecting part 503 extending outward from the slot of the mounting groove 5021. The rotating connecting part 503 is rotatably connected to the first connecting member 400 through a rotating shaft 600.

[0082] The first connector 400 has an intersecting first connecting surface 401 and a second connecting surface 402. When the handlebar 200 is in use, the first connecting surface 401 and the second connector 500 are opposite each other along the axial direction of the cross tube 100 (x-axis shown in the figure). When the handlebar 200 is in a folded state, the second connecting surface 402 and the second connector 500 are opposite each other along the axial direction of the cross tube 100 (x-axis shown in the figure).

[0083] A first connecting groove 4011 is provided on the first connecting surface 401, and a second connecting groove 4021 is provided on the second connecting surface 402. Both the first connecting groove 4011 and the second connecting groove 4021 are adapted to the connecting protrusion 9021.

[0084] When the handlebar 200 is in use, the connecting protrusion 9021 is connected to the first connecting groove 4011.

[0085] When the handlebar 200 needs to be folded, pulling the handlebar 200 causes the connecting section 201 to slide out of the cross tube 100. At this time, the second connecting member 500 slides to the second position, and the cross tube 100 releases the restriction on the first connecting member 400, applying downward pressure to the handlebar 200. This causes the handlebar 200 to drive the first connecting member 400 to rotate around the pivot 600. When the first connecting member 400 rotates, it will drive the connecting protrusion 9021 to slide from the first connecting groove 4011 to the second connecting groove 4021 and connect therein. During the process of the connecting protrusion 9021 sliding from the first connecting groove 4011 to the second connecting groove 4021, the elastic member 901 experiences a state of first stretching and then contracting. When the elastic member 901 contracts, it can pull the connecting protrusion 9021 to engage with the second connecting groove 4021 to achieve a segmented feel, thereby providing the user with a signal that the folding is complete.

[0086] refer to Figure 9 In this embodiment of the application, the connecting protrusion 9021 is arc-shaped, and the first connecting groove 4011 and the second connecting groove 4021 are arc-shaped.

[0087] When the arc-shaped connecting protrusion 9021 contacts the arc-shaped first connecting groove 4011 and the second connecting groove 4021, it can reduce wear and improve the uniformity of contact stress distribution on the mating surfaces of the two.

[0088] Continue to refer to Figure 9 In this embodiment of the application, the shape of the intersection area of ​​the first connecting surface 401 and the second connecting surface 402 between the first connecting groove 4011 and the second connecting groove 4021 is an arc-shaped surface.

[0089] The curved surface ensures a smooth transition as the connecting protrusion 9021 slides from the first connecting groove 4011 to the second connecting groove 4021, improving the smoothness of folding.

[0090] refer to Figure 8 In this embodiment of the application, the rotating connection part 503 includes two parts. The two rotating connection parts 503 are arranged opposite to each other and spaced apart along the radial direction (y-axis shown in the figure) of the horizontal tube 100. The two rotating connection parts 503 are respectively provided with a first rotating connection hole 5031.

[0091] The first connector 400 includes a fixed connecting part 403 and a transition part 404 connected to each other. The fixed connecting part 403 is fixedly connected to the connecting section 201, wherein the fixed connecting part 403 can be fixed to the connecting section 201 by crimping. The transition part 404 is disposed between two rotating connecting parts 503. The transition part 404 is provided with a second rotating connecting hole 4041, which corresponds to two first rotating connecting holes 5031. The rotating shaft 600 is rotatably connected to both the second rotating connecting hole 4041 and the two first rotating connecting holes 5031.

[0092] In other words, the adapter 404 rotates between the two rotating connecting parts 503 via the rotating shaft 600, and the two rotating connecting parts 503 can limit the adapter 404 in the radial direction (y-axis shown in the figure) of the horizontal tube 100.

[0093] Continue to refer to Figure 7 and Figure 8 The diameter of the fixed connection part 403 is smaller than that of the adapter part 404, so that an abutment surface is formed at the position where the fixed connection part 403 and the adapter part 404 are connected. When the fixed connection part 403 is pressed into the connecting section 201, the abutment surface abuts against the end face of the entrance of the connecting section 201, ensuring that the fixed connection part 403 is completely fixedly connected into the connecting section 201; at the same time, it prevents the adapter part 404 from entering the connecting section 201 and affecting the rotation of the adapter part 404.

[0094] This application also provides a vehicle that includes the folding handlebars described above.

[0095] The vehicle may include a scooter, a bicycle, or a wheelchair. The scooter may be an electric scooter, the bicycle may be an electric bicycle, and the wheelchair may be an electric bicycle.

[0096] In summary, this application provides a folding handlebar and a vehicle. The folding handlebar includes a cross tube 100 and two handlebars 200. Connecting segments 201 of the two handlebars 200 are slidably connected to both ends of the cross tube 100 along its axial direction (x-axis shown in the figure). Fasteners 300 are provided at both ends of the cross tube 100 along its axial direction to restrict the sliding of the connecting segments 201. A first connector 400 is fixedly provided on the connecting segment 201, and a second connector 500 is slidably connected inside the cross tube 100. The second connector 500 is connected via a pivot 60. The first connecting member 400 is rotatably connected to the first connecting member 400, and the rotating shaft 600 is perpendicular to the axis of the horizontal tube 100. When the second connecting member 500 slides along the axis of the horizontal tube 100 (x-axis shown in the figure) to the first position, the first connecting member 400 and the connecting section 201 are both located inside the horizontal tube 100, and the handlebar 200 is in use. When the second connecting member 500 slides along the axis of the horizontal tube 100 (x-axis shown in the figure) to the second position, the first connecting member 400 and the connecting section 201 are both located outside the horizontal tube 100, the first connecting member 400 can rotate around the rotating shaft 600, and the handlebar 200 is in a folded state.

[0097] The folding mechanism composed of the second connector 500 and the first connector 400 is simple in structure, small in size, and low in cost. It can achieve handlebar folding through a simple mechanical connection and avoids occupying too much handlebar space. When the handlebar 200 is in use, the second connector 500, the first connector 400, and the connecting section 201, which serve as the pivot point for the folding handlebar, are all located inside the cross tube 100. The rotation of the first connector 400 around the pivot 600 is restricted, and the pivot point is not subjected to force during the ride, which greatly increases the user's riding safety. At the same time, it also improves the structural strength of the folding handlebar and can prevent the handlebar 200 from shaking when encountering bumpy roads during the ride.

[0098] Furthermore, when the handlebar 200 is in use, the fastener 300 can lock the connecting section 201, ensuring that the handlebar 200 can no longer slide along the axial direction (x-axis shown in the figure) of the cross tube 100, preventing the handlebar 200 from sliding out of the cross tube 100 when in use, thus improving the structural stability of the folding handlebar and further increasing the safety of the user's riding.

[0099] The various embodiments or embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments, and the same or similar parts between the various embodiments can be referred to each other.

[0100] It should be noted that the terms "one embodiment," "embodiment," "exemplary embodiment," and "some embodiments" used in the specification indicate that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, such phrases do not necessarily refer to the same embodiment. Moreover, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments, whether explicitly described or not, is within the knowledge scope of those skilled in the art.

[0101] Generally speaking, terms should be understood at least in part by their use in context. For example, at least in part by context, the term "one or more" as used in the text can be used to describe any feature, structure, or characteristic of the singular meaning, or a combination of features, structures, or characteristics of the plural meaning. Similarly, at least in part by context, terms such as "a" or "the" can also be understood to convey either singular or plural usage.

[0102] It should be readily understood that the terms “on,” “above,” and “on top of” in this disclosure should be interpreted in the broadest possible sense, such that “on” means not only “directly on something” but also “on something” with an intermediate feature or layer therebetween, and that “above” or “on top of” means not only “on top of something” but also “on top of something” without an intermediate feature or layer therebetween (i.e., directly on something).

[0103] Furthermore, for ease of explanation, spatially relative terms such as "below," "below," "under," "above," and "above" may be used to describe the relationship of one element or feature relative to other elements or features as shown in the figures. Spatially relative terms are intended to encompass different orientations of the device in use or operation other than those shown in the figures. The device may have other orientations (rotated 90 degrees or in other orientations), and the spatially relative descriptive terms used herein may be interpreted accordingly.

[0104] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
