[0039] Refer to the following Figures 1 to 4 The handlebar structure and the vehicle according to the embodiments of the present application are described.

[0040] See also Figures 1 to 4As shown, an embodiment of the present application provides a handlebar structure, which includes a handlebar 1, a front fork 2, a locking bowl assembly 4, an elastic buffer 5 and a frame 3, wherein the handlebar 1 is connected to the front fork 2, the locking bowl assembly 4 is arranged on the front fork 2, and the locking bowl assembly 4 is located between the front fork 2 and the handlebar 1, the front fork 2 and the frame 3 are connected and locked through the locking bowl assembly 4, the elastic buffer 5 is elastic, and the elastic buffer 5 is arranged on the locking bowl assembly 4. When one of the handlebar 1 or the front fork 2 is subjected to external force, the elastic buffer 5 can be deformed due to its own elasticity, thereby offsetting the interaction force between the front fork 2 and the handlebar 1, and at the same time offsetting the twisting movement tendency of the locking bowl assembly 4, avoiding the loosening of the locking bowl assembly 4 and causing relative movement, thereby effectively avoiding the loosening between the handlebar 1 and the front fork 2, causing the handlebar 1 to shake.

[0041] Specifically, the handlebar 1 includes: a handlebar connecting portion 101 and a handlebar crossbar 102 . The handlebar crossbar 102 is used as a control part for the rider to control the direction, brakes, etc., and the handlebar connecting portion 101 is connected to the front fork 2 .

[0042] Furthermore, the front fork 2 includes: a front fork connecting portion 201 and a wheel connecting portion 202, the wheel connecting portion 202 is fixedly connected to the front fork connecting portion 201, and the wheel connecting portion 202 is used to connect the front wheel of a vehicle using the handlebar structure, so that the rider can drive the front wheel of the vehicle to change the direction of travel when manipulating the handlebar cross bar 102.

[0043] The front fork connection part 201 has a tube structure or a rod structure, and the front fork connection part 201 is provided with a first connection hole, and the first connection hole extends along the radial direction of the rod structure of the front fork connection part 201. The handlebar connection part 101 at least partially has a tube structure, specifically, the part of the handlebar connection part 101 used for connecting with the front fork connection part 201 has a tube structure, and the inner diameter of the handlebar connection part is slightly larger than the outer diameter of the front fork connection part 201, so that the end of the front fork connection part 201 away from the wheel connection part 202 can be inserted into the front fork connection part 201.

[0044] The side wall of the handlebar connecting part 101 is provided with second connecting holes, and there are two second connecting holes, which are arranged opposite to each other. After the end of the front fork connecting part 201 is inserted into the handlebar connecting part 101, one of the second connecting holes is arranged opposite to one end of the first connecting hole, and the other second connecting hole is arranged opposite to the other end of the first connecting hole, so that the handlebar 1 and the front fork 2 can be fixed by using bolts passing through the second connecting holes and the first connecting holes and locking with nuts.

[0045] Furthermore, the handlebar structure also includes a frame 3, which specifically includes a first connection portion 301 and a second connection portion 302. The first connection portion 301 is used to connect with the front fork 2, and the second connection portion 302 is used to connect with other components of the vehicle such as the rear fork. The first connection portion 301 and the second connection portion 302 are arranged at an angle, the first connection portion 301 is tubular, and the front fork connection portion 201 is inserted into the first connection portion 301.

[0046] Furthermore, the locking bowl assembly 4 includes: an upper locking bowl 401 and a lower locking bowl 402, both of which have an annular structure, and the upper locking bowl 401 and the lower locking bowl 402 are coaxially arranged with the first connecting part 301 and the front fork connecting part 201, and the two are sequentially sleeved on the front fork connecting part 201 and installed between the front fork connecting part 201 and the first connecting part 301, and the upper locking bowl 401 is located above the lower locking bowl 402, and the locking bowl assembly 4 can lock the front fork connecting part 201 and the first connecting part 301 to avoid shaking between the two. It should be noted that in this embodiment, the upper locking bowl 401 and the lower locking bowl 402 are common components in the prior art, and the fixing of the front fork 2 and the frame 3 by the locking bowl assembly 4 is also an existing mature technology. This part of the content is not the key protection content of this application, and those skilled in the art can fully understand it, so no excessive elaboration is made here.

[0047] Furthermore, the elastic buffer 5 is annular in structure as a whole. Preferably, the elastic buffer 5 is made of elastic metal stamping, which has the advantages of low cost and short production cycle. The elastic buffer 5 is composed of multiple spring leaves, and the spring leaves have a closed annular structure or a partially unclosed annular structure. The multiple spring leaves are distributed along the axial direction of the annular structure. Preferably, each spring leaf extends in a wave-like manner along its circumference. With this arrangement, not only each spring leaf has elasticity itself, but also the elastic buffer 5 composed of multiple spring leaves has good elasticity as a whole, and the elastic buffer 5 can shrink or rebound along its axial direction.

[0048] Specifically, in this embodiment, the number of the reeds may be four, namely a first reed 501, a second reed 502, a third reed 503 and a fourth reed 504. Figure 4 As shown, along the direction from top to bottom, the first reed 501, the second reed 502, the third reed 503 and the fourth reed 504 are arranged in sequence. Preferably, the first reed 501 and the fourth reed 504 have a long arc structure, and the first reed 501 and the fourth reed 504 are both wavy, the second reed 502 and the third reed 503 have a circular ring structure, and the second reed 502 and the third reed 503 are both wavy, both ends of the first reed 501 are connected to the upper side of the second reed 502, and both ends of the fourth reed 504 are connected to the lower side of the third reed 503.

[0049] More preferably, the trough position of the first reed 501 is connected to the crest position of the second reed 502, and correspondingly, the trough position of the second reed 502 is connected to the crest position of the third reed 503, and the trough position of the third reed 503 is connected to the crest position of the fourth reed 504. Through the combination of the above four reeds, the elastic buffer 5 as a whole has a mesh hollow ring structure, thereby ensuring that the elastic buffer 5 has good elasticity.

[0050] It should be noted that the number of reeds is not limited to four. The number of reeds can be increased or decreased according to the hardness requirements of the elastic buffer 5. When the number of reeds is more than four, multiple reeds are arranged in the same way as described above, with the first reed and the last reed being set as a semi-ring structure or a ring structure with a partial notch, and the reed in the middle position being set as a ring structure.

[0051] In the present application, a plurality of reeds are integrally formed and have an integrated structure, wherein a reed having a relatively long length is coiled several times to form a mesh-like hollow ring structure as described above.

[0052] Furthermore, a part of the height wall surface of the front fork connection part 201 is provided with threads, and the upper locking bowl 401 and the lower locking bowl 402 are threadedly connected to the front fork connection part 201. During assembly, the lower locking bowl 402 is first installed and fixed to the upper end port of the first connection part 301, and then the lower locking bowl 402 is threadedly connected to the front fork connection part 201 through an adaptive thread to ensure the stability between the front fork connection part 201 and the first connection part 301, and then the elastic buffer 5 is installed, and finally the upper locking bowl 401 is installed, and the upper locking bowl 401 is threadedly connected to the front fork connection part 201 through an adaptive thread. While the front fork connection part 201 and the first connection part 301 are locked by the upper locking bowl 401 and the lower locking bowl 402, The elastic buffer 5 is limited between the upper locking bowl 401 and the lower locking bowl 402, and in the process of tightening the upper locking bowl 401, the upper locking bowl 401 can squeeze the elastic buffer 5, so that the elastic buffer 5 is arranged between the upper locking bowl 401 and the lower locking bowl 402 in a slightly compressed state. When driving on a bumpy road, or when the handlebar 1 or the body of the bicycle falls or bumps, the elastic buffer 5 can be deformed. The deformation here can be axial expansion and contraction of the elastic buffer 5, or slight torsion of the elastic buffer 5 along the circumferential radial direction, thereby offsetting the relative movement between the upper locking bowl 401 and the lower locking bowl 402 and causing looseness, thereby avoiding shaking between the handlebar 1 and the front fork 2, resulting in dangerous situations such as difficulty in controlling the direction when riding and the handlebar 1 falling off.

[0053] Furthermore, the lock bowl assembly 4 also includes a gasket. Gaskets are arranged between the upper lock bowl 401 and the front fork connecting part 201, between the lower lock bowl 402 and the front fork connecting part 201, and between the lower lock bowl 402 and the first connecting part 301. By arranging the gasket, the locking effect of the lock bowl assembly 4 on the front fork 2 and the frame 3 can be strengthened, the risk of the lock bowl assembly 4 loosening can be further reduced, and the stability between the front fork 2 and the frame 3 can be enhanced.

[0054] Furthermore, the thread on part of the wall surface of the front fork connecting portion 201 corresponding to the upper locking bowl 401 and the lower locking bowl 402 serves as a groove 2011, and part of the spring leaf is clamped in the groove 2011, thereby enhancing the stability of the elastic buffer 5 between the upper locking bowl 401 and the lower locking bowl 402, and preventing the elastic buffer 5 from loosening or displacement.

[0055] In summary, the handlebar structure provided by the present application can effectively alleviate or offset the loosening of the lock bowl assembly 4 caused by factors such as road bumps or accidental bumps, which in turn causes the handlebar 1 to shake or even fall off, and other dangerous situations, by configuring the elastic buffer 5 for the lock bowl assembly 4. After testing, the handlebar structure provided by the present application has not loosened after 4 million vibration tests. Based on this, it can be fully predicted that the vehicle using the handlebar structure can meet at least a four-year riding cycle without the handlebar 1 of the bowl assembly loosening.

[0056] An embodiment of the present application also provides a vehicle, comprising the handlebar structure described in any of the above embodiments, and thus having all the beneficial technical effects of the handlebar structure, which will not be elaborated here.

[0057] It should be noted that the vehicle in this embodiment may be a bicycle, a two-wheeled electric vehicle, a three-wheeled electric vehicle, a motorcycle, etc.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
