[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figure 1 - Figure 3This utility model provides an embodiment of a pull-out handlebar for an electric scooter, including a vehicle body 1. A fixing frame 2 is provided on the right side of the vehicle body 1. The fixing frame 2 is the main support frame of the scooter in the prior art. A clamp 3 is provided on the outer wall of the top of the fixing frame 2. A secondary support 4 is slidably connected to the inner wall of the top of the fixing frame 2. The inner wall of the clamp 3 is in contact with the outer wall of the secondary support 4. The clamp 3 is in the prior art and has locking bolts on its surface. The locking bolts can be loosened by a special tool to remove the ribs of the secondary support 4, thereby extending the length of the secondary support 4 on the inner wall of the fixing frame 2. The clamp 3 can be locked again by a special tool, thereby fixing the secondary support 4 at multiple positions extending on the inner wall of the fixing frame 2. Handles a5 are hinged to both sides of the top of the secondary support 4. A folding component 6 is provided on the surface of the secondary support 4. An extension mechanism 7 is provided on the inner wall of the two sets of handles a5.
[0034] Reference Figure 2 and Figure 3 The extension mechanism 7 includes a handle b71, which is slidably connected to the inner wall of the handle a5. The inner wall of the handle a5 has a cavity. The handle b71 can be pulled and extended within the inner wall of the handle a5 to adjust for different arm extension sizes. The surface of the handle b71 has anti-slip holes for easy gripping by cyclists. A lever 73 is elastically connected to the inner wall of the handle b71 via a return spring 72. The lever 73 is slidably connected to the inner wall of the handle b71. The surface of the handle a5 has a groove, and the outer wall of the lever 73 is slidably connected to it. The handle a5 is connected to the inner wall of the slide groove. By opening a slide groove on the surface of the handle a5 and corresponding to the protrusion on the outer side of the toggle block 73, the handle a5 can also guide the movement of the toggle block 73. One end of the return spring 72 is fixedly connected to the outer wall of the toggle block 73, and the other end of the return spring 72 is fixedly connected to the inner wall of the handle b71. The function of the return spring 72 is to move the toggle block 73 so that the two sets of connecting rods 74 pull the corresponding positioning blocks 75 to move closer to each other and automatically reset the position. The end of the toggle block 73 away from the return spring 72 is hinged with two sets of connecting rods 74.
[0035] Reference Figure 3Two sets of connecting rods 74 are hinged to positioning blocks 75 at their ends away from the lever 73. When the lever 73 moves, the two sets of connecting rods 74 pull the corresponding positioning blocks 75 together, thereby disengaging them from the through hole at the current position of the handle a5. This facilitates the extension of the position of the handle b71. The connecting rods 74 are hinged at the lever 73 in a staggered manner. Multiple through holes are provided on the inner wall of the handle a5. The positioning blocks 75 pass through and slide on the end of the handle b71. The positioning blocks 75 are inserted into the inner wall of the through hole of the handle a5. This insertion allows the handle b71 to be adjusted and fixed on the inner wall of the handle a5 according to different arm spread widths, thereby avoiding discomfort caused by riding when the length is too narrow.
[0036] Reference Figure 2 and Figure 4 - Figure 5 The folding assembly 6 includes a slider 61. A groove is formed on the surface of the sub-support 4, and the slider 61 is slidably connected to the inner wall of the groove on the sub-support 4. By providing a guide groove on the surface of the sub-support 4 to fit the slider 61, the slider 61 can only move up and down within the inner wall of the sub-support 4 and cannot detach from it. One end of a limiting spring 63 is fixedly connected to the surface of the insertion rod 64, and the other end is fixedly connected to the inner wall of the slider 61. The limiting spring 63 automatically resets the position of the insertion rod 64 after it is pulled outward. Two sets of hinge rods 62 are hinged to the surface of the slider 61, with the two sets of hinge rods 62 being staggered front and rear on the surface of the slider 61. The end of the slider 62 away from the slider 61 is hinged to the outer wall of the handle a5. By moving the slider 61 up and down, the two sets of hinge rods 62 will push the corresponding handle a5 to unfold or fold at the top of the sub-support 4, making it convenient to carry and use. The inner wall of the bottom end of the slider 61 is elastically connected to the insertion rod 64 by the limiting spring 63. The insertion rod 64 passes through and slides on the inner wall of the slider 61. The inner wall of the sliding groove of the sub-support 4 has two sets of slots. The bottom end of the outer wall of the insertion rod 64 is inserted into the inner wall of the slot. The insertion between the two allows the slider 61 to move up and down to push the corresponding handle a5 to unfold and close, and then fix its position.
[0037] Working principle: When it is necessary to adjust the length of the sub-bracket 4 within the fixed frame 2, use a special tool to loosen the locking bolt on the clamp 3 to release the clamping effect of the clamp 3 on the sub-bracket 4. Then, you can manually pull the sub-bracket 4 to slide on the inner wall of the fixed frame 2 to adjust the extension length. After adjusting to the appropriate position, use a special tool to tighten the clamp 3 again. At this time, the clamp 3 tightly presses the sub-bracket 4, fixing the extension position of the sub-bracket 4 on the inner wall of the fixed frame 2, thereby changing the height of the entire handlebar part from the vehicle body 1 to adapt to different riding needs.
[0038] When the handle length needs to be adjusted according to the arm extension of different users, first grasp handle b71 and pull it outward. Handle b71 extends along the inner wall of handle a5. During the pulling process, handle b71 drives the lever 73 to slide along its inner wall. At the same time, lever 73 slides along the groove on the surface of handle a5. When lever 73 moves, it pulls the corresponding positioning blocks 75 together through the two sets of connecting rods 74. At this time, the return spring 72 is stretched, and after the positioning blocks 75 come together, they disengage from the through hole of the current position of handle a5, thus releasing the fixation of handle b71. The mechanism allows the handlebar b71 to continue to extend along the inner wall of the handlebar a5. Once the handlebar b71 has extended to the appropriate length to meet the rider's arm extension width requirements, the handlebar b71 is released. The lever 73 automatically resets under the elastic action of the return spring 72. After resetting, the lever 73 drives the positioning block 75 back to its original position via the connecting rod 74. The positioning block 75 is inserted into the corresponding through hole of the handlebar a5, fixing the handlebar b71 in the position adjusted according to different arm extension widths on the inner wall of the handlebar a5, thus avoiding discomfort caused by the handlebar being too narrow during riding.
[0039] When the handle a5 needs to be folded at the top of the sub-support 4 for easy carrying, first pull the insert rod 64 outward to disengage it from the slot in the inner wall of the slide groove of the sub-support 4. At this time, the limiting spring 63 is stretched. Then, push the slider 61 downward to slide on the inner wall of the slide groove of the sub-support 4. When the slider 61 moves, the two sets of hinge rods 62 hinged to its surface will rotate with the movement of the slider 61. Since the end of the hinge rod 62 away from the slider 61 is hinged to the outer wall of the handle a5, the hinge rod 62 will push the handle a5 to fold inward at the top of the sub-support 4, thus realizing the folding operation of the handle a5. When the handle a5 needs to be unfolded for use, the operation is reversed.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
