DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] Reference Figure 1 to Figure 4 The present embodiment provides a split handlebar structure, including a handlebar assembly, a stem assembly and a fastening assembly. The handlebar assembly includes a handlebar cross tube and an upper gland, which is welded and fixed to the upper side of the handlebar cross tube. The stem assembly includes a handlebar riser and a lower gland, which is welded and fixed to the upper end of the handlebar riser. The upper gland and the lower gland are fixed by a fastening assembly, and the upper gland and the lower gland are provided with mounting holes for the fastening assembly to pass through.
[0026] The working principle of the split handlebar structure of this embodiment is as follows:
[0027] The upper pressure cover welded on the handlebar cross tube and the lower pressure cover welded on the handlebar riser are fixedly connected through a fastening assembly, so that the handlebar cross tube and the handlebar riser are relatively fixed. The above connection structure does not need to be provided with a knurling structure, which reduces the processing difficulty and reduces the processing cost.
[0028] It should be noted that, in the existing split handlebar structure, the thickness of the upper gland is generally 5 mm, so that the nut can be welded on the upper gland. As a possible example, in this embodiment, the nut is not welded on the upper gland, so the thickness of the upper gland can be reduced accordingly. For example, the thickness of the upper gland is greater than 2 mm and less than 4 mm, and preferably 3 mm, so as to reduce the material used for the upper gland and reduce the material cost.
[0029] As a possible example, in this embodiment, the upper gland includes an upper semi-cylinder, a first upper connecting plate and a second upper connecting plate, the first upper connecting plate and the second upper connecting plate are respectively located on both sides of the upper semi-cylinder, and the upper semi-cylinder is respectively connected to the first upper connecting plate and the second upper connecting plate as a whole. The inner side surface of the upper semi-cylinder is welded to the upper side of the middle portion of the handlebar cross tube.
[0030] The lower pressure cover includes a lower semi-cylinder, a first lower connecting plate and a second lower connecting plate. The first lower connecting plate and the second lower connecting plate are respectively located on both sides of the lower semi-cylinder. The lower semi-cylinder is respectively connected to the first lower connecting plate and the second lower connecting plate as a whole.
[0031] The first upper connecting plate is fixedly connected to the first lower connecting plate through a fastening assembly. The second upper connecting plate is fixedly connected to the second lower connecting plate through a fastening assembly.
[0032] In this embodiment, the cross-section of the upper semi-cylinder and the lower semi-cylinder is approximately semicircular, so as to better adhere to the outer side of the middle part of the handlebar cross tube.
[0033] As a possible example, in this embodiment, two vertical plates are provided on the first lower connecting plate, and mounting holes are provided on the vertical plates. The vertical plates are perpendicular to and integrally connected to the first lower connecting plate, and the two vertical plates are opposite to each other and are respectively located on both sides of the first upper connecting plate. The two vertical plates can be used to install the basket or other components.
[0034] As a possible example, in this embodiment, the first upper connecting plate is fixedly connected to the first lower connecting plate by one fastening assembly, and the second upper connecting plate is fixedly connected to the second lower connecting plate by two fastening assemblies. Due to the existence of the two vertical plates, the area of the first lower connecting plate is smaller than that of the second lower connecting plate, so only one fastening assembly needs to be arranged at the center position of the first lower connecting plate.
[0035] As a possible example, in this embodiment, a pin hole is provided at the lower end of the handlebar riser, and the pin hole is perpendicular to the axis of the handlebar riser. After the lower end of the handlebar riser passes through the mounting tube at the front end of the frame, it is connected to the wheel bracket through a pin shaft passing through the pin hole.
[0036] As a possible example, in this embodiment, the fastening assembly includes bolts and nuts, and the fastening assembly is not welded to the upper gland or the lower gland. Those skilled in the art may also use other types of fastening assemblies, such as a combination of studs and nuts.
[0037] As a possible example, in this embodiment, the handlebar cross tube is generally curved, and when in use, its middle portion (the portion used to connect the upper gland and the lower gland) is generally arranged horizontally. The handlebar riser can be arranged vertically or inclined when in use.
[0038] This embodiment also provides a vehicle, including the above-mentioned split handlebar structure. Since the vehicle includes the above-mentioned split handlebar structure, it also has the above-mentioned advantages of the split handlebar structure, which will not be described in detail here.
[0039] The present invention uses specific examples to illustrate the principle and implementation of the present invention. The above examples are only used to help understand the method and core idea of the present invention. At the same time, for those skilled in the art, according to the idea of the present invention, there will be changes in the specific implementation and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
