[0032] In order to further understand the application content, features and effects of this application, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0033] Example 1

[0034] See also Figure 1 , Figure 1This is a three-dimensional diagram of a folding handlebar structure. The folding handlebar structure in this example includes a stem 1 and two handle mechanisms 2. The stem is used to support the two handle mechanisms 2 and connect to the vehicle body. The handle mechanisms 2 are used to facilitate the user to control balance and direction.

[0035] Please also refer to Figure 2 and Figure 3 , Figure 2 This is a cross-sectional view of the folding handlebar structure. Figure 3 Schematic diagram of the coordination relationship between the stem and the connecting assembly, wherein the stem includes a vertical rod 11 and a main rod 12, the main rod 12 is vertically connected to the vertical rod 11, and a groove 121 is provided at each end of the main rod 12; the handle mechanism 2 includes a connecting assembly 21, a handlebar 22 and a grip 23; the connecting assembly 21 includes a connecting shaft 211 and a connecting member 212, the connecting shaft 211 is radially arranged on the main rod 12, one end of the connecting member 212 is arranged in the groove 121 and is rotatably connected to the connecting shaft 211, and the other end extends into the handlebar 22, the handlebar 22 is sleeved on one end of the main rod 12, is clamped with the main rod 12, and is threadedly connected to the connecting member 212, and the grip 23 is provided on the handlebar 22; the two handle mechanisms 2 are respectively located at both ends of the main rod 12.

[0036] In this example, the vertical rod 11 is used to connect to the front fork arm of the bicycle, the handle is T-shaped, and the two handle mechanisms 2 are symmetrically arranged at both ends of the main rod 12. The groove 121 is arranged radially along the main rod 12, and the connecting member 212 is movably arranged in the groove 121 along the opening direction of the groove 121. In this example, the connecting member 212 rotates in the groove 121 along the height direction, and rotates through the groove 121 axially. The handlebar 22 is provided with an internal thread.

[0037] In specific application, the stem is mounted on the front fork arm of the bicycle body. When riding the bicycle, the user holds the two handle mechanisms 2 with both hands. When the handlebars need to be folded, the user rotates the handlebar 22, and the handlebar 22 rotates relative to the main rod 12, so that the threads of the handlebar 22 and the threads of the connecting member 212 are loosened, and the handlebar 22 gradually moves away from the main rod 12 until the handlebar 22 is no longer engaged with the main rod 12, that is, the handlebar 22 is no longer sleeved on the main rod 12, and at this time the connecting member 212 can move in the groove 121. At this time, the handlebar 22 is still threadedly connected to the connecting member 212, that is, the handlebar 2 2 is not completely separated from the threaded connection state of the connecting member 212, and then the handlebar 22 is rotated along the side opening direction of the groove 121, and the connecting member 212 rotates relative to the connecting shaft 211, and the folding step of the folding handlebar structure is completed; when the folding handlebar structure needs to be unfolded, the user rotates the handlebar 22 relative to the main rod 12 so that the handlebar 22 is parallel to the main rod 12, and then rotates the handlebar 22 so that the thread of the handlebar 22 is locked with the thread of the connecting member 212 until one end of the handlebar 22 is sleeved on the main rod 12, and the handlebar 22 and the main rod 12 are locked, thereby completing the folding step of the folding handlebar structure.

[0038] In this way, by providing grooves 121 at both ends of the main rod 12, the connecting shaft 211 passes through the grooves 121 and is provided on the main rod 12, and a connecting piece 212 that can move along the grooves 121 is provided, so as to realize the rotational connection between the stem 1 and the handle mechanism 2. At the same time, the main rod 12 and the handlebar 22 are clamped together by the handlebar 22 being sleeved on the main rod 12. The connecting piece 212 is threadedly connected to the main rod 12, so that the handlebar 22 can move toward the main rod 12 or move away from the main rod 12, thereby realizing that the handlebar 22 is sleeved on the main rod 12 or completely withdrawn from the main rod 12. When the handlebar 22 is completely withdrawn from the main rod 12, the handlebar 22 and the main rod 12 are no longer clamped, and the handlebar 22 can rotate relative to the main rod 12, thus completing the folding of the folding handlebar structure.

[0039] Please also refer to Figure 4 and Figure 5 , Figure 4 This is a diagram showing the relationship between the stem and the handlebar. Figure 5 This is a schematic diagram of the connecting component structure. Further, the connecting part 212 includes a sleeve 2121, a connecting rod 2122 and a limiting column 2123. One end of the connecting rod 2122 is fixedly connected to the sleeve 2121, and the other end is fixedly connected to the limiting column 2123. The sleeve 2121 is sleeved on the connecting shaft 211 and is rotatably connected to the connecting shaft 211. One end of the connecting rod 2122 extends into the groove 121, and the other end extends into the handlebar 22. The limiting column 2123 has an external thread, which is located in the handlebar 22 and is threadedly connected to the handlebar 22.

[0040] Specifically, the sleeve 2121 is sleeved on the connecting shaft 211 to realize the rotational connection between the connecting piece 212 and the main rod 12. The diameter of the limiting column 2123 is larger than the diameter of the connecting rod 2122. The external thread of the limiting column 2123 is matched with the internal thread of the handle bar 22. The handle bar 22 is rotated, and the handle bar 22 rotates relative to the limiting column 2123. The connecting rod 2122 connects the limiting column 2123 and the main rod 12, and the handle bar 22 can move relative to the main rod 12.

[0041] In this way, the handle bar 22 is connected to the main bar 12 , or the handle bar 22 is no longer sleeved on the main bar 12 .

[0042] Furthermore, the handle 22 has a first section 221, a second section 222 and a third section 223 connected in sequence, the first section 221, the second section 222 and the third section 223 are all cylindrical, and the inner wall diameter of the first section 221 is larger than the inner wall diameter of the second section 222, and the length of the second section 222 is larger than the length of the first section 221; the first section 221 is sleeved on the main rod 12 and clamped with the main rod 12, the second section 222 is sleeved on the limiting column 2123 and is threadedly connected to the limiting column 2123, and the handle is sleeved on the third section 223.

[0043] Specifically, the first segment 221 faces the main rod 12, the second segment 222 is located between the first segment 221 and the third segment 223, the third stage is facing away from the main rod 12, and there are shoulders between the first segment 221 and the second segment 222, and between the second segment 222 and the third segment 223. When the third segment 223 of the handle 22 is rotated, the internal thread of the second segment 222 cooperates with the external thread of the limiting column 2123, and the second segment 222 can move relative to the limiting column 2123, and the second segment 222 faces away from the main rod 12. After the movement, the first segment 221 follows the second segment 222 to move, and the first segment 221 is no longer sleeved on the main rod 12, that is, the first segment 221 is no longer clamped to the main rod 12, and the main rod 12 can swing relative to the main rod 12; align the axis of the first segment 221 with the axis of the main rod 12, rotate the third segment 223, and after the second segment 222 moves toward the direction facing the main rod 12, the first segment 221 follows the second segment 222 to move, and the first segment 221 can be sleeved on the main rod 12, realizing the clamping connection between the first segment 221 and the main rod 12.

[0044] Furthermore, the connecting assembly 21 further includes an elastic member 213 , which is sleeved on the connecting rod 2122 , with one end thereof abutting against the main rod 12 , and the other end abutting against the second segment 222 ; the elastic member 213 is a spring.

[0045] In this way, the user can be assisted in rotating the handle 22 .

[0046] Furthermore, the diameter of the inner wall surface of the second segment 222 is greater than the diameter of the inner wall surface of the third segment 223 .

[0047] In this way, the second section 222 can limit the main rod 12 to prevent the user from rotating the main rod 12 too many times and causing the main rod 12 to enter the second section 222 .

[0048] Furthermore, the grip 23 is provided at one end of the handle 22 facing away from the main rod 12 , and the grip 23 is provided with anti-slip grooves 231 .

[0049] In this way, the friction force when the user grips the handle 23 can be increased.

[0050] Example 2

[0051] The bicycle handlebar in this example includes the folding handlebar structure in the first embodiment.

[0052] In summary, by setting grooves at both ends of the main rod, the connecting shaft passes through the grooves and is set on the main rod, and a connecting piece that can move along the groove is set, the rotational connection between the handlebar and the handle mechanism is realized. At the same time, the main rod and the handlebar are clamped together by the handlebar being sleeved on the main rod. The connecting piece is threadedly connected to the main rod so that the handlebar can move toward the main rod or away from the main rod, thereby realizing the handlebar being sleeved on the main rod or completely withdrawn from the main rod. When the handlebar is completely withdrawn from the main rod, the handlebar and the main rod are no longer clamped, and the handlebar can rotate relative to the main rod, thereby completing the folding of the folding handlebar structure.

[0053] The above is merely an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included within the scope of the claims of the present application.
