Detailed Description of the Embodiment
[0033] The following further describes the present application in detail with reference to the drawings.
[0034] The embodiment of the present application discloses a connected handlebar for an electric vehicle. Refer to Figure 1 and Figure 2, the integrated handlebar includes a handlebar tube 1. At both ends of the handlebar tube 1, there are inserted handles 2. At the bottom of the handlebar tube 1, there is welded a riser tube 3. The riser tube 3 is made of a metal tube and is bent into a U shape. Both ends of the riser tube 3 are fixedly connected to the handlebar tube 1. At the bottom of the riser tube 3, there is welded an insertion tube 31. At the bottom of the riser tube 3, there abuts an installation seat 4. The installation seat 4 is welded to the top of the front fork riser of the electric vehicle. The top surface of the installation seat 4 is recessed into an arc shape that matches the bottom of the riser tube 3, and at the center position of the top surface of the installation seat 4, there is opened an installation hole 41 for the insertion tube 31 to be snap-fitted. At the bottom of the riser tube 3, there is provided a pipe clamp 5. The pipe clamp 5 abuts against the side of the riser tube 3 away from the installation seat 4, and the bottom of the pipe clamp 5 is in an arc shape that matches the circumferential wall of the riser tube 3. At the four corners of the top surface of the pipe clamp 5, there are respectively penetrated fastening bolts 51. The threaded section of the fastening bolt 51 is inserted into the installation seat 4 and is threadedly connected to the installation seat 4.
[0035] When using this integrated handlebar, by inserting the insertion tube 31 at the bottom of the riser tube 3 into the installation seat 4, and then adjusting the position where the bottom of the riser tube 3 abuts against the installation seat 4, so that the circumferential wall of the riser tube 3 is in full contact with the top surface of the installation seat 4. Place the pipe clamp 5 on the side of the riser tube 3 away from the installation seat 4, adjust the position of the pipe clamp 5 so that the bottom surface of the pipe clamp 5 is in full contact with the circumferential wall of the riser tube 3. Use the fastening bolt 51 to tightly connect the pipe clamp 5 and the installation seat 4. At the same time, clamp and fix the riser tube 3 between the installation seat 4 and the pipe clamp 5. By inserting the insertion tube 31 at the bottom of the riser tube 3 into the installation seat 4, the stability of the connection between the riser tube 3 and the installation seat 4 can be ensured. When the fastening bolt 51 becomes loose, the insertion tube 31 can ensure that the connection between the riser tube 3 and the handlebar tube 1 does not rotate, ensuring that the driver can normally rotate the handlebar to control the steering of the electric vehicle and ensuring the safe driving of the electric vehicle.
[0036] Refer to Figure 2 and Figure 3 , the inner diameter at both ends of the handlebar tube 1 is larger than the outer diameter of the section of the handle 2 inserted into the handlebar tube 1, and an elastic washer 21 is sleeved on the circumferential wall of the handle 2. After the handle 2 is inserted into the handlebar tube 1, the elastic washer 21 is clamped between the end faces of the handlebar tube 1 and the handle 2. On the inner wall of the handlebar tube 1, there is welded a fixing plate 22. On the side of the fixing plate 22 away from the handle 2, there is penetrated a screw rod 23, and the threaded section of the screw rod 23 passes through the fixing plate 22 and the handle 2 and extends outside the handle 2. At one end of the screw rod 23 away from the fixing plate 22, there is threadedly connected a nut 231. On the circumferential wall of the end of the handle 2 away from the handlebar tube 1, there is machined a bolt groove 6. At the abutting position between the nut 231 and the bottom of the bolt groove 6, there is machined an anti-slip thread.
[0037] When using this integrated handlebar, the handle 2 inserted at both ends of the handlebar tube 1 is fastened by the screw rod 23. The anti-slip threads can ensure the stable connection between the nut 231 and the screw rod 23. When the electric vehicle is running on the road surface, the handle 2 and the handlebar tube 1 can telescopically move stably within a certain stroke. When the handle 2 moves, the elastic washer 21 can reduce the vibration generated by the collision between the handlebar tube 1 and the handle 2, reduce the amplitude of the handle 2 shaking caused by the vibration of the road surface, reduce the vibration received by the driver's hand when holding the handle 2 while riding the electric vehicle, and improve the comfort of the driver when riding the electric vehicle.
[0038] Refer to Figure 2 , a coil 9 is fixedly connected to the peripheral wall on one side of the riser 3. There are four coils 9 and they are arranged at intervals along the height direction of the riser 3. When using this integrated handlebar, the wire harness passing through the riser 3 is wound in the coil 9, which can limit the wire harness and ensure that the wire harness will not affect the operation of the driver and the rotation of the integrated handlebar during driving.
[0039] Refer to Figure 2 , anti-slip sections 10 are formed by machining on the section of the handlebar tube 1 close to the handle 2. There are two anti-slip sections 10 arranged at intervals and both are located between the two handles 2. When using this integrated handlebar, the handle controller is sleeved on the anti-slip section 10 and fastened, which can increase the stability of the handle controller fixation and ensure the safety during the driving of the electric vehicle.
[0040] Refer to Figure 2 , bolt seats 11 are welded to the peripheral wall of the section of the handlebar tube 1 close to the anti-slip section 10. There are two bolt seats 11 and both are located between the two threaded sections. When using this integrated handlebar, the threaded section of the rearview mirror is inserted into the bolt seat 11 and fastened. Compared with the method of fixing the rearview mirror on the handlebar through a ferrule, it can increase the stability of the rearview mirror fixation.
[0041] Refer to Figure 3 , an anti-slip handle 7 is welded to the outer wall of the bolt groove 6. When using this integrated handlebar, the anti-slip handle 7 can ensure that the hand of the rider will not slip off from one end of the handle 2, improve the safety when driving the electric vehicle, and when the electric vehicle topples during driving, the anti-slip handle 7 can protect the hand of the rider from being scratched by the ground.
[0042] Refer to Figure 3 , an anti-slip cover 8 is clamped in the bolt groove 6. A clamping groove 61 is formed in the inner wall of the bolt groove 6. There are four clamping grooves 61 arranged at intervals along the peripheral wall of the bolt groove 6. A clamping block 81 that matches the clamping groove 61 is formed on the peripheral wall of the anti-slip cover 8. An anti-slip groove 82 that can be sleeved on the nut 231 is formed on the bottom surface inside the anti-slip cover 8.
[0043] When using this combined handlebar, snap the anti - detachment cover 8 into the bolt groove 6. At this time, the anti - slip groove 82 of the anti - detachment cover 8 sleeves and positions the nut 231 away from one end of the bolt. At the same time, the clamping block 81 is snapped into the clamping groove 61, which can prevent the nut 231 from loosening due to rotation caused by vibration, and ensure the stability of the fixation between the handlebar and the handlebar tube 1.
[0044] This specific embodiment is only an interpretation of the present application and is not a limitation thereof. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as they are within the scope of the claims of the present application, they are protected by the patent law.
