All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Fig. 1 is an exploded schematic view of a vertical foldable mechanism according to an embodiment of the present invention, fig. 2a is a schematic view of a cross-sectional structure of a rotating structure of the vertical foldable mechanism according to an embodiment of the present invention, and fig. 2b is a schematic view of a cross-sectional structure of a rotating structure of a vertical foldable mechanism according to the prior art.

As shown in fig. 1 and 2a, the vertical folding mechanism includes: a body 3 and a handle 1 rotatably connected to the body 3. In the embodiment of the present invention, the rotation shaft 22 is provided on the body 3, and the rotation part 21 is provided on the handle 1. It should be understood, however, that the rotating shaft 22 may be provided on the handle 1 and the rotating portion 21 may be provided on the body 3. As long as one of the body 3 and the handle 1 is provided with the rotation shaft 22, and the other of the body 3 and the handle 1 is provided with the rotation portion 21. The rotating shaft 22 is located at one end of the body 3 close to the handle 1 or at one end of the handle 1 close to the body 3, and the rotating part 21 can be rotatably surrounded on the rotating shaft 22. The mating surfaces of the rotating portion 21 and the rotating shaft 22 include a first curved surface 101 that is the same as the folding direction Y of the handle 1 and has the same radius of curvature r as the rotating shaft 22, and a second curved surface 102 that is connected to the first curved surface 101 and has a larger radius of curvature r than the rotating shaft 22.

The vertical folding mechanism provided by the embodiment of the invention arranges the matching surfaces of the rotating part 21 and the rotating shaft 22 to be the same as the folding direction Y of the handle 1 and the curvature radius r of the rotating shaft 22 as well as a first curved surface 101 connected with the first curved surface 101 and a second curved surface 102 larger than the curvature radius r of the rotating shaft 22. Since the radius of curvature of the second curved surface 102 is larger than the radius of curvature r of the rotational shaft 22, it is possible to ensure easy assembly of the rotational portion 21 with the rotational shaft 22. Because the curvature radius R of the first curved surface 101 is the same as the curvature radius R of the rotating shaft 22, the first curved surface 101 can be attached to the rotating shaft 22, so that the surface contact between the rotating part 21 and the rotating shaft 22 is realized, and compared with the technical scheme that the existing rotating shaft 22a is in line contact with the rotating part 21a shown in fig. 2b, the swinging of the rotating shaft 22 in the rotating part 21 in the X direction can be effectively reduced, and the user experience is increased.

Fig. 3a is an exploded view of a rotating part of a vertical foldable mechanism according to an embodiment of the present invention, fig. 3b is an enlarged view of a second rotating part of the vertical foldable mechanism along a direction a1 according to an embodiment of the present invention, and fig. 3c is an enlarged view of a first rotating part of the vertical foldable mechanism along a direction a2 according to an embodiment of the present invention.

Referring to fig. 3a, in one embodiment, the rotating portion 21 of the upright folding mechanism may include two spaced apart arcuate plates 2115 and at least one reinforcing rib 2116 connected between the two arcuate plates 2115. Thus, the material consumption of the rotating part 21 can be reduced and the weight of the handle 1 can be reduced on the premise of maintaining the structural strength of the rotating part 21.

In one embodiment, the rotating portion 21 may include a first rotating portion 211 and a second rotating portion 212 fixedly connected to each other, wherein the first curved surface 101 is located at the first rotating portion 211 and the second curved surface 102 is located at the second rotating portion 212. By providing the rotating portion 21 as a separate structure, the first curved surface 101 on the first rotating portion 211 and the second curved surface 102 on the second rotating portion 212 having different radii of curvature can be easily machined separately, and the machining and manufacturing processes of the rotating portion 21 can be simplified.

In one embodiment, the first rotating portion 211 and the second rotating portion 212 are fixedly connected by a threaded fastener 23. The threaded fastener may be a bolt or a screw, however, the threaded fastener is not particularly limited by the embodiments of the present invention. The first and second

rotating portions

211 and 212 can be conveniently disassembled and assembled by fixedly connecting them using a threaded fastener.

By arranging at least one limiting protrusion 2122 and at least one limiting recess 2112 which are matched with each other around the threaded fastener 23, the axial sliding of the first mounting part 211 and the second mounting part 212 can be well limited, and the vertical foldable mechanism is prevented from shaking in the using process. The limiting protrusion 2122 may be L-shaped, and the limiting recess 2112 may also be L-shaped, so that the limiting protrusion 2122 and the limiting recess 2112, which are matched with each other, can limit axial sliding of the first mounting portion 211 and the second mounting portion 212 and radial movement of the first mounting portion and the second mounting portion 212.

Through embedded cooperation, the embedding part 311 of the body 3 is embedded into the embedded cooperation part 321 of the handle 1, and the body 3 and the handle 1 are connected through the cooperation of the second hook 41 and the clamping groove 42, so that the length of the second hook 41 can be shortened, and the strength of the second hook 41 is increased. The failure of the fit between the second hook 41 and the slot 42 is prevented.

Obviously, the above-mentioned embedded matching structure effectively solves the problem of matching the handle 1 and the body 3, however, there is a long-standing problem that the user may feel loose between the handle 1 and the body 3 during the operation process, which seriously affects the use experience.

Meanwhile, the gap between the connection surface of the machine body 3 and the handle 1 is reduced, and the user experience is increased.

Referring to fig. 8 and 9, the surface of the insertion part 311 includes a protrusion, and the surface of the insertion fitting part 321, which is engaged with the insertion part 311, may be processed to be flat for manufacturing convenience, so that the insertion part 311 may form an interference fit with the surface of the insertion fitting part 321 by the protrusion of the surface thereof. However, it should be understood that the surface of the insert-fitting portion 321 which is fitted with the insert portion 311 may be formed with a groove which is fitted with a projection of the insert portion 311, so that the body 3 is prevented from being detached from the handle 1 when the upright foldable mechanism is in the upright state by forming a snap-fit connection by the projection of the surface of the insert portion 311 and the groove of the surface of the insert-fitting portion 321. The surface shape of the insertion fitting portion 321 fitted to the insertion portion 311 is not particularly limited in the embodiments of the present invention.

In an embodiment, the vertical foldable mechanism may further include an unlocking mechanism 4, which drives the second hook 41 to be disengaged from the slot 42, and the unlocking mechanism may drive the second hook 41 to move or drive the second hook 41 to rotate, but the embodiment of the present invention is not limited thereto.

In one embodiment, the rotating shaft 22 includes two shaft ends 221 spaced apart from each other and a shaft body 222 connected between the two shaft ends 221, wherein the cross-sectional area of the shaft end 221 is larger than the cross-sectional area of the shaft body 222, and the rotating portion 21 is accommodated between the two shaft ends 221 and surrounds the shaft body 222. Note: the cross section herein means a cross section taken along the axis of the shaft end 221 or the shaft body 222 in a direction perpendicular to the shaft end 221 or the shaft body 222. The axial sliding of the rotating portion 21 can be restricted by providing the two shaft ends 221, and the stability of the fitting of the rotating portion 21 and the rotating shaft 22 is improved.
