Description

Technical Field

[0001] The utility model relates to the technical field of handle covers, in particular to an anti-falling handle cover for an electric vehicle. Background Art

[0002] The handle is mounted on the end of the handlebar of an electric vehicle to improve the stability and comfort of the driver when holding the handlebar to control the vehicle. Generally, the handle cover is made of rubber material and is fixed to the handlebar by being mounted on the handlebar and having an interference fit with the handlebar. In the prior art, in order to strengthen the stability of the handle cover connected to the handlebar and prevent the handle cover from falling off the handlebar, an anti-falling structure is provided on the handle cover. For example, the utility model patent: An electric vehicle handle cover with an anti-falling structure (Announcement No.: CN219257604U) discloses a handle cover that achieves an anti-falling function by cooperating with a nylon expansion block and an aluminum alloy expansion sleeve. The anti-falling function is achieved by the nylon expansion block being stuck in the aluminum alloy expansion sleeve to cause the aluminum alloy expansion sleeve to deform and expand. When the handle cover is aged and needs to be replaced, even if the nylon expansion block is released to tighten the aluminum alloy expansion sleeve, the aluminum alloy expansion sleeve is still in an open state because it has no recovery after expansion, which makes it more troublesome to disassemble the handle cover.

[0003] In view of the above problems, the present invention makes improvements. Utility Model Content

[0004] The utility model provides an anti-falling electric bicycle handle cover, which solves the above-mentioned problems existing in the prior art during use.

[0008] Preferably, a positioning pile is formed at the center of the end face of the support plate away from the closed end of the sleeve body, and the support rod is fixedly connected to the positioning pile.

[0009] Preferably, a reinforcing plate is fixedly connected to the ends of several of the support rods, and the end of the transmission screw is rotatably connected to the reinforcing plate.

[0010] Preferably, the outer wall of the free end of the expansion arm is arc-shaped and several anti-slip protrusions are formed on the outer wall of the free end of the expansion arm.

[0011] Preferably, the expansion block is frustum-shaped and the small head end of the expansion block faces the expansion arm, and the inner wall of the expansion arm is in the shape of an inclined plane matching the inclined plane of the expansion block.

[0012] Preferably, a butting pile is formed at the center of the end face of the support plate facing the closed end of the sleeve body, a butting hole matching the butting pile is opened at the closed end of the sleeve body, the butting pile passes through the butting hole and abuts against the connecting plate, and a sliding hole is opened on the end face of the butting pile.

A limiting hole matching the limiting part is formed on the inner wall of the operating hole. The limiting ring abuts against the connecting plate under the action of the spring, so that the limiting part passes through the operating hole and penetrates into the limiting hole.

[0013] In summary, the beneficial effects of the present invention are as follows: The function of preventing detachment is realized by driving the expansion block with the transmission screw to push the expansion arm against the inner wall of the handlebar. When disassembling the handlebar cover, rotate the transmission screw to drive the expansion block to withdraw from between the free ends of several expansion arms. After the expansion arm loses the tight abutment of the expansion block, it swings away from the position where it tightly abuts against the inner wall of the handlebar, making the expansion arm loose from the handlebar. At this time, pull the sleeve body outwards to remove it from the handlebar to realize the disassembly of the handlebar cover. Since there is almost no force restricting the relative displacement between the expansion arm and the inner wall of the handlebar during the disassembly of the handlebar cover, the disassembly operation is very labor-saving and convenient, facilitating the operation when replacing the handlebar cover.

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying Figures 1-4 , in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0021] As shown in the figure, an anti-detachment electric vehicle handlebar sleeve includes a sleeve body 1. The sleeve body 1 is a circular tube with one end closed. A support plate 2 is fixedly connected to the closed end of the sleeve body 1. A plurality of support rods 3 are fixedly connected to the support plate 2 and are arranged in a circular array along the center of the support plate 2 and extend axially into the sleeve body 1. A support seat 4 is fixedly connected to the plurality of support rods 3. A plurality of expanding arms 5 are hinged to the support seat 4 and are arranged in a circular array along the axis of the sleeve body 1. A plurality of expanding blocks 6 that can slide into the free ends of the plurality of expanding arms 5 are arranged on the plurality of support rods 3. A transmission screw 7 screwed to the expanding block 6 is rotatably arranged at the center of the support plate 2, and the end of the transmission screw 7 passes through the closed end of the sleeve body 1.

[0022] Specifically, the structure in which the support plate 2 is fixedly connected to the sleeve body 1: On the end face of the support plate 2 facing the closed end of the sleeve body 1, a number of connecting sleeves 21 are formed. The support plate 2 abuts against the inner wall of the closed end of the sleeve body 1, so that the connecting sleeves 21 penetrate into a number of connecting holes 11 opened on the closed end of the sleeve body 1. A connecting plate 8 is provided on the outer wall of the closed end of the sleeve body 1. A number of connecting bolts 83 that correspond to the number of connecting sleeves 21 one by one and are screwed into the connecting sleeves 21 are inserted through the connecting plate 8, and an operation hole 81 aligned with the transmission screw rod 7 is opened at the center of the connecting plate 8. By the cooperation of the connecting bolts 83 and the connecting sleeves 21, the support plate 2 and the connecting plate 8 are tightened to clamp the closed end of the sleeve body 1, realizing the detachable connection between the support plate 2 and the sleeve body 1.

[0023] In the above-mentioned embodiment, when the handlebar cover is installed on the handlebar, the sleeve body 1 is sleeved on the outer wall of the handlebar, so that the support rod 3 and the expansion blocks 6 and expansion arms 5 arranged on the support rod 3 extend into the handlebar. After the sleeve body 1 is installed in place, the end of the handlebar abuts against the support plate 2. Then, the transmission screw rod 7 is rotated by passing through the end of the closed end of the sleeve body 1. The transmission screw rod 7 drives the expansion block 6 to slide on the support rod 3 towards the expansion arm 5 through the threaded cooperation with the expansion block 6. The expansion block 6 sliding towards the expansion arm 5 enters between the free ends of a number of expansion arms 5 and contacts the inner wall of the expansion arm 5, pushing the expansion arm 5 to swing towards the inner wall of the handlebar, so that the outer wall of the free end of the expansion arm 5 tightly abuts against the inner wall of the handlebar. Through the friction force between the two, the expansion arm 5 and the handlebar are fastened, and further the handlebar cover and the handlebar are fastened, preventing the handlebar cover from falling off the handlebar to achieve the anti-falling function. When it is necessary to disassemble the handlebar cover, the transmission screw rod 7 is rotated to drive the expansion block 6 to withdraw from between the free ends of a number of expansion arms 5. After the expansion arm 5 loses the tight abutment of the expansion block 6, it swings away from the position where it tightly abuts against the inner wall of the handlebar, loosening the expansion arm 5 and the handlebar. At this time, the sleeve body 1 is pulled outwards to remove it from the handlebar, and the disassembly of the handlebar cover can be realized. Since the expansion arm 5 hardly has a force restricting the relative displacement between the two during the disassembly of the handlebar cover and the inner wall of the handlebar, the disassembly operation is very labor-saving and convenient, facilitating the operation when replacing the handlebar cover. After the handlebar cover is removed, the connecting bolts 83 are removed to separate the support plate 2 and the connecting plate 8, and the anti-falling structure composed of the support plate 2, the support rod 3, the expansion block 6, the expansion arm 5 and the transmission screw rod 7 is removed from the sleeve body 1. At this time, only the aging sleeve body 1 needs to be replaced, thus saving the later use cost of the handlebar cover.

[0024] Preferably, a positioning pile 22 is formed at the center of the end face of the support plate 2 away from the closed end of the sleeve body 1. The support rod 3 is fixedly connected to the positioning pile 22. The outer diameter of the positioning pile 22 matches the inner diameter of the handlebar. When installing the handlebar grip, during the process of sleeving the sleeve body 1 on the outer wall of the handlebar, the positioning pile 22 is inserted into the port of the handlebar to support the support plate 2 and thus the handlebar grip, which enhances the stability of the handlebar grip installed on the handlebar. At the same time, through the positioning function of the positioning pile 22 inserted into the handlebar, when several expansion arms 5 extend into the interior of the handlebar, they are accurately located at the center of the handlebar, so as to better tightly abut against the inner wall of the handlebar when pushed by the expansion block 6 to achieve the anti-detachment function.

[0025] Preferably, a reinforcing plate 9 is fixedly connected to the ends of several support rods 3. The end of the transmission screw 7 is rotatably connected to the reinforcing plate 9. The reinforcing plate 9 enhances the stability of several support rods 3 and the transmission screw 7, and also enhances the supporting strength of the support rods 3 for the expansion block 6 and the expansion arms 5, so as to ensure a more stable anti-detachment function achieved by the cooperation of the expansion block 6 and the expansion arms 5.

[0026] Preferably, the outer wall of the free end of the expansion arm 5 is arc-shaped and several anti-slip protrusions 51 are formed on the outer wall of the free end of the expansion arm 5. The arc-shaped outer wall of the free end of the expansion arm 5 increases the contact area between it and the inner wall of the handlebar when they are in contact, and the anti-slip protrusions 51 enhance the friction between them, thereby enhancing the stability of the expansion arm 5 when tightly abutting against the inner wall of the handlebar and ensuring the stability of the anti-detachment function.

[0027] Preferably, the expansion block 6 is frustum-shaped and the small head end of the expansion block 6 faces the expansion arm 5. The inner wall of the expansion arm 5 is in the shape of an inclined plane matching the inclined plane of the expansion block 6. When the expansion block 6 pushes the expansion arm 5 to tightly abut against the inner wall of the handlebar, the inclined plane of the expansion block 6 fits with the inclined plane-shaped inner wall of the expansion block 6, increasing the contact area between the expansion block 6 and the expansion arm 5, and enhancing the supporting effect of the expansion block 6 on the expansion arm 5, so as to ensure the stability of the anti-detachment function.

[0028] Further, a butting pile 23 is formed at the center of the end face of the support plate 2 facing the closed end of the sleeve body 1. An abutting hole 12 matching the butting pile 23 is formed in the closed end of the sleeve body 1. The butting pile 23 passes through the abutting hole 12 and abuts against the connecting plate 8, and a sliding hole 24 is formed in the end face of the butting pile 23. A driving part 71 in the shape of a multi-prismatic column is formed at the end of the driving screw rod 7 penetrating into the sliding hole 24. An operating rod 10 is arranged in the sliding hole 24. A driving hole 101 matching the driving part 71 is formed in the end face of the operating rod 10 facing the driving screw rod 7. The driving part 71 penetrates into the driving hole 101. A limiting ring 102 matching the sliding hole 24 is formed on the circumferential side surface of the operating rod 10. A spring 25 abutting against the limiting ring 102 is arranged in the sliding hole 24. A limiting part 103 in the shape of a multi-prismatic column is formed at the end of the operating rod 10 away from the driving screw rod 7. A limiting hole 82 matching the limiting part 103 is formed on the inner wall of the operating hole 81. The limiting ring 102 abuts against the connecting plate 8 under the action of the spring 25, so that the limiting part 103 passes through the operating hole 81 and penetrates into the limiting hole 82.

[0029] In the above preferred embodiment, the operating rod 10 and the driving screw rod 7 can realize the rotational transmission between the two through the cooperation of the driving hole 101 and the driving part 71. After the limiting part 103 penetrates into the limiting hole 82, the rotational limit of the limiting hole 82 restricts the rotation of the operating rod 10, and thus restricts the rotation of the driving screw rod 7, so that the expansion block 6 can be more stably maintained at the position driven by the driving screw rod 7. When the expansion block 6 pushes the expansion arm 5 to expand and tightly abuts against the inner wall of the handlebar, it is more stable, thereby ensuring the stability of the anti-detachment function. When it is necessary to rotate the driving screw rod 7 to drive the expansion block 6, the operating rod 10 is pressed inward to slide inward in the sliding hole 24 and compress the spring 25, so that the limiting part 103 leaves the limiting hole 82. At this time, the driving screw rod 7 can be rotated by rotating the operating rod 10. In order to facilitate the rotation of the operating rod 10, an inner hexagonal hole is formed on the end face of the operating rod 10. After rotating the operating rod 10 to drive the driving screw rod 7 and then drive the expansion block 6 to move in place, the operating rod 10 is released to slide outward in the sliding hole 24 under the action of the spring 25, so that the limiting part 103 penetrates into the limiting hole 82 again to apply a rotational limit to the driving screw rod 7.

[0030] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
