[0040] Figure 1 A first perspective view of the handle sleeve provided by the embodiment of the present disclosure is shown. Figure 2 A sectional view of the handle sleeve provided by the embodiment of the present disclosure is shown. The handle sleeve 100 is provided with a sleeve opening at one end and has an exhaust hole 21 at the other end. In the process of sleeving the handle sleeve 100 on the handlebar 210 through the sleeve opening, the air inside the handle sleeve 100 is squeezed and discharged through the air hole 21. When the handle sleeve 100 is installed in place, the exhaust hole 21 is closed, and a negative pressure cavity is formed in the flexible sleeve part 1, so that the handle sleeve 100 is tightly fitted on the handlebar 210 and cannot be easily detached.

[0041] In some possible embodiments, the handle sleeve 100 includes a flexible sleeve part 1, an end piece part 2 and a film part 3. The flexible sleeve part 1 has an inner cavity 15. The flexible sleeve part 1 is provided with a first port and a second port 11 at two ends along the length direction, respectively. The first port and the second port 11 are both communicated with the inner cavity 15. The end piece part 2 is arranged at one end of the flexible sleeve part 1, and covers the first port. The end piece part 2 is provided with an exhaust hole 21 communicated with the inner cavity. The film part 3 is connected to the end piece part, and covers the exhaust hole 21. The film part 3 is provided with an exhaust slit 31. The handle sleeve 100 is configured to open the exhaust slit 31 of the film part 3 to communicate the inner cavity 15 and the exhaust hole 21 to discharge the gas in the inner cavity 15 in the process of sleeving on the handlebar 210 through the second port 11. When the handle sleeve 100 is installed in place, the exhaust slit 31 of the film part 3 is closed to close the exhaust hole 21.

[0042] The handle sleeve 100 can be made of soft plastic material or silica gel material, has soft and comfortable hand feeling, and has good flexibility, so that the inner surface can be tightly fitted on the handlebar 210 when sleeving on the handlebar 210. Figure 5A partial structure schematic diagram of a two-wheeled vehicle handlebar sleeve in a separated state is shown. Figure 6 A partial structure schematic diagram of a two-wheeled vehicle handlebar sleeve in a separated state is shown. Figure 5 An enlarged view of the middle A part. There is no air or better air between the inner wall of the handlebar sleeve 100 and the outer surface of the handlebar 210. The handlebar sleeve 100 is tightly matched with the handlebar 210, and the handlebar sleeve 100 will not easily separate from the handlebar 210. The end of the handlebar 210 is a closed structure, and the surface is flat or convex, without a recessed groove. When the handlebar sleeve 100 is completely sleeved on the handlebar 210, the end of the handlebar 210 is attached to the end piece part 2 of the handlebar sleeve 100, and the film part 3 is pressed tightly, so that the film part 3 is closed, and external air cannot enter the inside of the handlebar sleeve 100 through the film part 3.

[0043] It should be noted that the flexible sleeve part 1, the end piece part 2, and the film part 3 can be made of the same material, that is, the handlebar sleeve 100 can be a one-piece molded part.

[0044] In some possible embodiments, as shown in Figure 2 The end piece part 2 has an exposed surface 22 and an inner side surface 23 constituting one side boundary of the inner cavity 15. The exposed surface 22 is exposed to the surface of the handlebar sleeve 100, and the inner side surface 23 is located on one side of the inner cavity 15. The film part 3 is arranged on the inner side surface 23.

[0045] The film part 3 is hidden inside the handlebar sleeve 100 and is not exposed, which can be protected by the flexible sleeve part 1 and will not be damaged, so that the reliability of the handlebar sleeve 100 is high. The film part 3 is arranged on the inner surface of the handlebar sleeve 100, and when the handlebar sleeve 100 is sleeved on the handlebar 210, the surface of the handlebar 210 can abut against the film part 3 to close the exhaust gap 31 on the film part 3. External air cannot enter the inside of the handlebar sleeve 100 through the exhaust hole 21 on the film part 3, so that the space between the handlebar sleeve 100 and the handlebar 210 is kept in a negative pressure state, which is conducive to keeping the handlebar sleeve 100 tightly connected to the handlebar 210.

[0046] In some possible embodiments, the thickness of the film part 3 can be 0.15mm-1.25mm. The film part 3 is provided with an exhaust gap 31 at a position opposite to the exhaust hole 21. When the thickness of the film part 3 is too large, the exhaust gap is difficult to close, which is not conducive to keeping the inside of the handlebar sleeve 100 in a negative pressure state. When the thickness of the film part 3 is too small, the film part 3 is easy to be damaged, resulting in failure. A large number of experiments have verified that when the thickness of the film part 3 is 0.15mm-1.25mm, the performance of the film part 3 is good after the handlebar sleeve 100 is sleeved on the handlebar 210. The exhaust gap 31 on the film part 3 can be effectively opened and closed, the film is relatively strong and not easy to be damaged, has good durability, and has high reliability.

[0047] In some possible embodiments, the grip 100 is either a soft plastic part or a silicone part. By using a flexible material, the grip 100 has a soft and comfortable grip, and the grip 100 has good flexibility so that when it is put on the handlebar 210, the inner surface of the grip 100 fits tightly to the handlebar 210 and the grip 100 will not easily fall off the handlebar 210.

[0048] Figure 3 This image shows a second view of the handlebar sleeve provided in an embodiment of this disclosure. (In conjunction with...) Figure 2 and Figure 3 As shown, an inner protruding ring 12 is provided on the inner wall of the flexible sleeve 1 on one side of the second port 11. The handlebar sleeve 100 is configured such that, when it is fitted onto the handlebar 210, the inner protruding ring 12 fits tightly against the outer surface of the handlebar 210.

[0049] With the grip 100 fitted onto the handlebar 210, the inner protruding ring 12 on the grip 100 is stretched open and in an elastic deformation state. The inner protruding ring 12 fits tightly against the handlebar 210, forming a fastening effect. The inner protruding ring 12 can also seal the gap between the flexible sleeve 1 and the handlebar 210, so that the inside of the grip 100 is in a sealed state, preventing outside air from entering the grip 100. The inside of the grip 100 is kept under negative pressure, allowing the grip 100 to be stably attached to the handlebar 210.

[0050] Figure 4 This is a third-view view of the handlebar grip provided in an embodiment of the present disclosure. A glue inlet 13 is provided on the flexible sleeve portion 1. To improve the reliability of the assembly structure between the handlebar grip 100 and the handlebar 210, after the handlebar grip 100 is fitted onto the handlebar 210, glue can be injected into the flexible sleeve portion 1 through the glue inlet 13. This glue fills the space between the inner wall of the flexible sleeve portion 1 and the outer wall of the handlebar 210, effectively bonding the flexible sleeve portion 1 and the handlebar 210. Simultaneously, by injecting glue into the handlebar grip 100, air in the gap between the handlebar grip 100 and the handlebar 210 can be further expelled, strengthening the vacuum effect in the circumferential direction of the handlebar grip 100 and extending the vacuum duration. This allows the connection structure between the handlebar grip 100 and the handlebar to be used outdoors for many years.

[0051] In some possible implementations, the glue inlet 13 is located near the second port 11, and the glue inlet 13 is located on the side of the inner convex ring 12 near the end piece 2, so that the glue inlet 13 connects the sealed space formed between the grip 100 and the handlebar 210. The glue inlet 13 is located on the side of the second port 11 of the grip 100, which allows glue to be gradually filled from one end of the sealed space, which is beneficial to fill the inner wall of the grip 100 with glue and avoid unfilled areas. Applying glue on the side of the second port 11 can gradually drive away the air between the grip 100 and the handlebar 210 from the side of the second port 11 towards the vent 21.

[0052] In some possible embodiments, as shown in Figure 3 The inner wall of the flexible sleeve part 1 is provided with a plurality of ribs 14, each of which is arranged along the circumference of the flexible sleeve part 1 and extends along the length direction of the flexible sleeve part 1. The ribs 14 are located between the inner convex ring 12 and the end piece part 2 and do not interfere with the sealing fit structure of the handlebar 210 and the inner convex ring 12. By arranging a plurality of ribs 14, when the handlebar cover 100 is arranged on the handlebar 210, the ribs 14 tightly press the surface of the handlebar 210, thereby improving the stability of the connection structure of the handlebar cover 100 and the handlebar 210.

[0053] The embodiments of the present disclosure also provide a two-wheeled vehicle, Figure 5 A partial structure schematic view of a handlebar cover of a two-wheeled vehicle in a separated state is shown. Figure 6 An enlarged view of part A in Figure 5 is shown. Figure 7 A partial structure schematic view of a handlebar cover of a two-wheeled vehicle connected to a handlebar is shown. Figure 8 A structure schematic view of a two-wheeled vehicle is shown. The two-wheeled vehicle comprises a frame 200 and the handlebar cover 100 described above. The frame 200 has a handlebar 210, which has a cylindrical wall 211 and an end wall 212 located at the end of the cylindrical wall 211 and connected to the cylindrical wall 211. The flexible sleeve part 1 of the handlebar cover 100 is sleeved on the cylindrical wall 211, the inner wall of the flexible sleeve part 1 of the handlebar cover 100 is attached to the cylindrical wall 211, and the end piece part 2 of the handlebar cover 100 is attached to the end wall 212 of the handlebar 210. The end wall 212 can be an outward convex surface or a flat surface, so that when the handlebar cover 100 is sleeved on the handlebar 210, the end wall 212 can be stably attached to the end piece part 2 as a whole and can effectively support the film part 3, so that the exhaust gap 31 on the film part 3 can be effectively closed.

[0054] In some possible embodiments, the cylindrical wall 211 and the end wall 212 are connected and transitioned through an annular chamfer surface 213. The annular chamfer surface 213 is generally conical, the outer diameter of the side close to the end wall 212 is small, for example, smaller than the inner diameter of the second port 11 of the flexible sleeve part 1, and the outer diameter of the side away from the end wall 212 can be larger than the inner diameter of the second port 11 of the flexible sleeve part 1, thereby facilitating the smooth sleeving of the flexible sleeve part 1 on the handlebar 210.

[0055] The above description has been given for the purpose of illustration and description. Furthermore, this description is not intended to limit the embodiments of the present disclosure to the forms disclosed herein. Although a plurality of example aspects and embodiments have been discussed above, those skilled in the art will recognize certain variations, modifications, changes, additions and sub-combinations thereof.
