Detailed Implementation
[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0016] like Figures 1-12 As shown, this utility model proposes an adjustable height rear footrest for a two-wheeled electric vehicle. The rear footrest mainly includes a C-shaped mounting bracket 1, which is the basic structure of the entire bracket and is used to securely install the bracket on the two-wheeled electric vehicle. On the bottom plate of the C-shaped mounting bracket 1, there is a hexagonal wrench box 12, and a sliding cover 13 is movably provided on its top, which facilitates the user to store and retrieve the hexagonal wrench used by the loosening component 6. Inside the top plate of the C-shaped mounting bracket 1, there is an internal threaded cylinder 10, which is one of the key components for realizing height adjustment. An adjustment component 2 is provided inside, and the top of the adjustment component 2 is connected to the footrest component 3 for the user to rest their feet. At the same time, a loosening component 6 is also provided on the inner wall of the C-shaped mounting bracket 1, which plays a role in ensuring the stability of the bracket. The adjusting component 2 mainly consists of a screw 20 and a rotating wheel 21. The screw 20 is threaded inside the internal threaded cylinder 10. The height can be adjusted by rotating the screw 20. The bottom of the screw 20 is fixedly connected to the rotating wheel 21. The user can easily drive the screw 20 to rotate inside the internal threaded cylinder 10 by rotating the rotating wheel 21. When the rotating wheel 21 rotates clockwise, the screw 20 rises; when the rotating wheel 21 rotates counterclockwise, the screw 20 falls. The top of the screw 20 is provided with a bearing 22. The function of the bearing 22 is to reduce the friction between the foot support component 3 and the screw 20, so that the foot support component 3 can rotate more smoothly during height adjustment, and also helps to maintain the stability of the foot support component 3. The foot support assembly 3 is fitted onto the bearing 22 and includes a foot support block 30 and a foot support block 33 connected thereto. The foot support block 30 is fitted onto the bearing 22 and can move up and down with the lifting and lowering of the screw 20. A slot 15 is provided on one side of the top of the C-shaped mounting bracket 1. A limit guide plate 31 is provided at the position of the foot support block 30 corresponding to the slot 15. The limit guide plate 31 is embedded in the slot 15. Its function is to limit and guide the foot support block 30 during the lifting and lowering process of the foot support assembly 3, prevent the foot support block 30 from shifting or shaking, and ensure the accuracy and stability of the height adjustment. A second foot block 33 is movably mounted on the top corner of the foot rest block 30 away from the limiting guide plate 31 via a hinge pin 32. This allows the second foot block 33 to rotate around the hinge pin 32. When it is necessary to expand the foot rest area to accommodate users with different foot widths, the second foot block 33 can be rotated to be flush with the first foot block 30. The first foot block 30 and the second foot block 33 are symmetrically provided with insertion holes 2 34, and each has an insertion hole 35 on its front side. The two are fixed together by a fixing rod 36. In normal use, the fixing rod 36 is inserted into the insertion hole 2 34 to fix the first foot block 30 and the second foot block 33 into a whole. When it is necessary to adjust the state of the second foot block 33, the fixing rod 36 can be pulled out. In addition, a slide cylinder 37 is provided on one side of the foot block 33. A fixing post 38 is movably installed inside the slide cylinder 37. A pull rod 311 is connected to the tail of the fixing post 38. A pull head 310 is provided at the top of the end of the pull rod 311 located outside the slide cylinder 37 for easy pulling by the user. A compression spring 39 is provided between the fixing post 38 and the inner top surface of the slide cylinder 37. The function of the fixing post 38 is to fix the fixing rod 36 and prevent it from falling off. To increase friction when resting the feet and prevent the user's feet from slipping, the top of the first footrest block 30 is provided with a first anti-slip texture 4, and the top and bottom of the second footrest block 33 are provided with a second anti-slip texture 5. The inner wall of the C-shaped mounting bracket 1 has a pair of sliding grooves 14. The anti-loosening component 6 includes a pair of fixing handles 60. Each fixing handle 60 has a slider 61 at its tail. The slider 61 fits perfectly into the sliding groove 14, allowing the fixing handle 60 to move along the sliding groove 14 on the inner wall of the C-shaped mounting bracket 1. The top of the fixing handle 60 has a clamping head 62. The two clamping heads 62 are arranged opposite each other. Several barbs 63 are provided on the inner wall. When it is necessary to fix the screw 20 and prevent it from rotating, the two fixing handles 60 are pushed to make the clamping heads... The clamping head 62 grips the top of the screw 20, and the clamping bar 63 increases the friction between the clamping head 62 and the screw 20, further enhancing the fixing effect. A nut 64 is fixedly installed on the outer wall of one of the fixing handles 60, and the other fixing handle 60 is fixed to the nut 64 by an internal hex bolt 65. In use, the internal hex bolt 65 is passed through the fixing handle 60 and screwed into the nut 64. By tightening the internal hex bolt 65, the clamping force of the two clamping heads 62 on the screw 20 can be adjusted to ensure that the screw 20 is firmly fixed.
[0017] When using this device, height adjustment is very simple. Just rotate the wheel 21. When the wheel 21 rotates forward, the screw 20 rotates in one direction in the internal threaded cylinder 10, thereby driving the foot support assembly 3 to rise. If the wheel 21 rotates in reverse, the screw 20 rotates in the opposite direction, and the foot support assembly 3 lowers accordingly, thus meeting the personalized needs of different users for foot support height. After the height is adjusted to the appropriate position, the height of the foot support assembly 3 needs to be fixed. At this time, a hex wrench can be taken out from the hex wrench box 12 and the internal hex bolt 65 can be turned. As the internal hex bolt 65 is turned, the two clamping heads 62 connected to it gradually approach and hug the bottom of the screw 20, increasing the friction and effectively preventing the screw 20 from rotating, thereby limiting the height of the foot support assembly 3 and ensuring that the height of the foot support assembly 3 will not change arbitrarily during use. If the user's feet are wide enough that the existing footrest area is insufficient, refer to... Figure 2 To operate, first, pull out the fixing rod 36 to release the fixation restriction on the second foot support block 33; then, manually rotate the second foot support block 33 to flip it to be flush with the first foot support block 30, increasing the bearing area of the foot support; next, manually pull the pull head 310 to retract the fixing post 38, then insert the fixing rod 36 into the insertion hole 35 to fix the first foot support block 30 and the second foot support block 33 again. Release the pull head 310, and under the action of the compression spring 39, the fixing post 38 rebounds, passes through the fixing rod 36, and limits its movement, ensuring that the two foot support blocks are firmly connected during use, providing users with comfortable and stable foot support.
