Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a locking mechanism, a handlebar system, and a vehicle. Background Technology

[0002] Bicycles and electric bikes are important means of transportation, convenient and environmentally friendly, and are loved by people. Especially in big cities where road congestion is very serious, lightweight and flexible means of transportation are the first choice for people to travel. Bicycles and electric bikes are smaller in size, easier to learn and operate than traditional fuel vehicles, and are quieter and safer when driving, making them very advantageous for short-distance travel.

[0003] The function of the handlebar system of the above vehicles is to control the front wheel. The handlebar system includes handlebars, front fork stem, and locking mechanism. The handlebars and front fork stem are connected by the locking mechanism. The front fork stem is connected to the head tube with the front wheel, so that the handlebar system controls the direction of the front wheel to control the direction of the electric vehicle.

[0004] Please see below. Figure 1 , Figure 1 The diagram shows the structure of a locking mechanism in the prior art. The locking mechanism includes a first locking mechanism 1' for connecting the fork steerer tube and a second locking mechanism 2' for connecting the handlebars. The first locking mechanism 1' includes two connectors 11', each with a connecting hole 12' for accommodating the fork steerer tube. The two connectors 11' are locked together by a threaded connector 13', thus locking the fork steerer tube within the connecting hole 12'. However, the threaded connector 13' is located behind the fork steerer tube (here, "behind" refers to the side of the fork steerer tube furthest from the handlebars), occupying a significant amount of space behind the fork steerer tube and impacting riding comfort.

[0005] Therefore, this application provides a new locking mechanism, handlebar system, and vehicle to address the above-mentioned problems. Utility Model Content

[0060] This arrangement places the first opening 12 near the locking seat 3 on the first locking member 1, and the second opening 22 near the locking seat 3 on the second locking member 2.

[0061] The first opening 12 is located on the left and right sides of the vertical diameter 4 and is situated near the locking seat 3 of the first locking member 1, thus being far from the rear of the fork steerer tube and further reducing the impact on riding.

[0062] Optionally, the first end is provided with a first fixing hole, the second end is provided with a second fixing hole 13, and the first fastener can pass through the second fixing hole 13 and be tightened into the first fixing hole; or, the third end is provided with a third fixing hole 23, the fourth end is provided with a fourth fixing hole, and the second fastener can pass through the third fixing hole 23 and be tightened into the fourth fixing hole.

[0067] For example, the first locking element 1 may have two, three, or four locking elements, and the second locking element 2 may have two, three, or four locking elements. This arrangement improves the connection strength and stability of the locking mechanism to the handlebars and fork steerer tube.

[0068] Optionally, a first reinforcing plate is connected between adjacent first locking members 1, or a second reinforcing plate is connected between adjacent second locking members 2.

[0069] Preferably, in this embodiment, a first reinforcing plate is connected between adjacent first locking members 1, and a second reinforcing plate is connected between adjacent second locking members 2.

[0074] When assembling the handlebar system of this embodiment, the second fastener is unlocked to enlarge the second opening 22, and the handlebar is inserted into the second locking hole 21. The second opening 22 is then locked by the second fastener, thus locking the handlebar into the second locking hole 21. The first fastener is then unlocked to enlarge the first opening 12, and the fork steerer is inserted into the first locking hole 11. The first opening 12 is then locked by the first fastener, thus locking the fork steerer into the first locking hole 11.

[0075] In the locking mechanism, since the first opening 12 is located on the left or right side of the vertical diameter 4, after the fork steerer is inserted into the first locking hole 11, the first fastener is located on the left and right sides of the fork steerer, rather than on the rear side of the fork steerer.
