Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of electric vehicle riser tubes, specifically relating to a quick-locking electric vehicle folding riser tube structure. Background Technology
[0002] Current riser structures are divided into two categories:
[0003] 1. Fixed riser: It adopts an integrated rigid welded structure, which cannot be folded, resulting in inconvenience in storage and carrying (such as taking up too much volume in narrow spaces).
[0004] 2. Folding riser: including pin-type and snap-on structures. The pin-type structure achieves connection through the pin hole, but frequent insertion and removal can easily wear down the hole wall, leading to increased gaps and loosening of the lock; the snap-on structure uses mechanical interlocking for locking, but it is prone to deformation after long-term use, reducing reliability, and may be accidentally unlocked during vibration.
[0005] Folding risers are cumbersome to fold / unfold, taking 1 to 3 minutes. Some steps require tools. Furthermore, loose bolts or pins can easily lead to riser misalignment and loss of steering control, resulting in low safety. When folding / unfolding is in place, there is no "locked in place" feedback, making it difficult for users to judge the locking status. This can easily lead to over-locking / folding, damaging the equipment and affecting subsequent use. Utility Model Content
[0006] The purpose of this invention is to provide a quick-locking folding riser structure for electric vehicles, aiming to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A quick-locking electric vehicle folding upright structure includes a folding locking component, comprising an upper upright tube and a lower upright tube disposed below the upper upright tube. A folding shaft is fixedly connected inside the upper upright tube, and a self-locking component is disposed outside the folding shaft. A telescopic component is disposed inside the upper upright tube. The rigid locking component includes a groove, which is formed inside the end of the upper upright tube adjacent to the lower upright tube. An internal locking slider is movably connected inside the groove.
[0009] As a preferred embodiment of this utility model, the self-locking assembly includes a handle, which is rotatably connected to the outside of the folding shaft, and the folding shaft is rotatably connected to the inside of the lower upright tube. A first tension spring is fixedly connected inside the handle, and a self-locking push block is fixedly connected to the end of the first tension spring away from the handle. Two first fixing screws are internally threaded to the self-locking push block, and self-locking hangers are externally threaded to the two first fixing screws. A locking hook is fixedly connected to the outside of the upper upright tube.
[0010] As a preferred embodiment of this utility model, the self-locking plate is attached to the self-locking push block by two first fixing screws, the bottom inner side of the self-locking plate is beveled, and the self-locking plate is engaged with the locking hook. The folding shaft is rotatably connected to the bottom eccentric position of the handle.
[0011] As a preferred embodiment of this utility model, the telescopic component includes a telescopic tube, which is inserted into the interior of the upper vertical tube. A quick-release pipe clamp locking unit is provided at the connection between the upper vertical tube and the telescopic tube, and a quick-release pipe clamp is provided at the top of the telescopic tube.
[0012] In a preferred embodiment of this utility model, the quick-release tube clamp is connected to the handlebars, and the quick-release tube clamp locking unit is fixedly connected to the upper stem via a slot.
[0013] As a preferred embodiment of this utility model, the upper tube is internally threaded with two second fixing screws, and the inner locking slider has two sliding grooves at corresponding positions of the two second fixing screws. The inner locking slider is internally fixedly connected with two spring set screws, and a second tension spring is fixedly connected to the side of each spring set screw near the second fixing screw. An eccentric shaft top block is fixedly connected to the side of the inner locking slider near the folding shaft.
[0014] As a preferred embodiment of this utility model, the eccentric shaft top block corresponds to the position of the self-locking component, the end of the second tension spring away from the spring top screw contacts the second fixing screw, the second fixing screw passes through the sliding groove and is threaded into the inside of the upper tube, and the front end of the internal locking slider is provided with two arc-shaped protrusions, and the two arc-shaped protrusions are engaged in the two grooves of the upper tube and the lower tube.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. With the folding locking component, folding / unfolding can be completed within ten seconds by simply pushing the self-locking push block and turning the handle. No tools are required. The mechanical locking sound ("click") and the handle limit travel allow the user to intuitively judge the locking status and avoid insecure locking or excessive operation.
[0017] 2. Through the rigid locking component, the internal locking slider is embedded in the groove of the upper and lower stem tubes, combined with the secondary locking of the handle (the self-locking plate and the locking hook are engaged) to prevent loosening or accidental unlocking during riding, thus improving stability. The entire stem tube is made of 6061 aluminum alloy in one piece, which reduces the weight by 30% compared to the steel structure, reducing the overall load on the vehicle. At the same time, the rigid locking component is built-in, with a smooth appearance to avoid scratches and dust accumulation, and the built-in rigid locking component also improves the overall aesthetics.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0028] Example 1
[0029] Reference Figures 1-6This is the first embodiment of the present utility model. This embodiment provides a quick-locking electric vehicle folding upright structure, including a folding locking component, including an upper upright 10, a lower upright 11 disposed below the upper upright 10, a folding shaft 12 fixedly connected inside the upper upright 10, a self-locking component 13 disposed outside the folding shaft 12, and a telescopic component 14 disposed inside the upper upright 10.
[0030] The self-locking component 13 allows the upper upright tube 10 and the lower upright tube 11 to be folded and locked together, and the folding function can be realized around the folding axis 12, making it smaller and more convenient to transport.
[0031] Furthermore, the self-locking assembly 13 includes a handle 131, which is rotatably connected to the outside of the folding shaft 12. The folding shaft 12 is rotatably connected to the inside of the lower upright tube 11. A first tension spring 132 is fixedly connected inside the handle 131. A self-locking push block 133 is fixedly connected to the end of the first tension spring 132 away from the handle 131. Two first fixing screws 135 are threaded inside the self-locking push block 133. A self-locking hanging piece 134 is threaded outside the two first fixing screws 135. A locking hook 136 is fixedly connected to the outside of the upper upright tube 10.
[0032] The self-locking plate 134 is attached to the self-locking push block 133 by two first fixing screws 135. The bottom inner side of the self-locking plate 134 is beveled, and the self-locking plate 134 is engaged with the locking hook 136. The folding shaft 12 is rotatably connected to the bottom eccentric position of the handle 131.
[0033] The upper riser 10 and the lower riser 11 can switch between folding and unfolding states via the folding shaft 12, and the state switch can be completed within ten seconds.
[0034] Preferably, the telescopic assembly 14 includes a telescopic tube 141, which is inserted into the interior of the upper riser 10. A quick-release tube clamp locking unit 142 is provided at the connection between the upper riser 10 and the telescopic tube 141. A quick-release tube clamp 143 is provided at the top of the telescopic tube 141. The quick-release tube clamp 143 is connected to the handlebars. The quick-release tube clamp locking unit 142 is fixedly connected to the upper riser 10 through a slot.
[0035] It should be noted that when adjusting the height of the quick-release pipe clamp 143, loosen the quick-release pipe clamp locking unit 142, and then pull the telescopic pipe 141 inside the upper riser 10. After adjusting to the appropriate angle, tighten the quick-release pipe clamp locking unit 142. The adjustment is convenient and quick.
[0036] In use, when the upper riser 10 and lower riser 11 are in the folded state, the upper riser 10 is located to the right of the lower riser 11, and the handle 131 is located between the upper riser 10 and the lower riser 11. At this time, the handle 131 is in the following state: Figure 6When the upper riser 10 and lower riser 11 need to be unfolded for use, rotate 180 degrees and press down the self-locking push block 133 to disengage the self-locking hanging piece 134 from the locking hook 136 outside the upper riser 10. Rotate the upper riser 10. At this time, the position of the handle 131 remains unchanged while the position of the upper riser 10 changes. When the upper riser 10 rotates to vertical and its bottom is in contact with the top of the lower riser 11, rotate the handle 131 counterclockwise. During the rotation, the locking hook 136 squeezes the inclined side of the self-locking hanging piece 134, causing the self-locking push block 133 to gradually move away from the folding axis 12. At this time, the first tension spring 132 is compressed. When the handle 131 is rotated to vertical, the locking hook 136 no longer contacts the inclined side of the self-locking hanging piece 134. At this time, the first tension spring 132 rebounds and drives the self-locking push block 133 to descend, so that the self-locking hanging piece 134 and the locking hook 136 engage. Folding / unfolding can be achieved by simply rotating the handle 131, which takes less than ten seconds.
[0037] It should be noted that when the self-locking plate 134 and the locking hook 136 engage, a "click" sound will be produced, which increases the mechanical locking sound and allows for a direct judgment of the locking status, avoiding incomplete locking or excessive operation.
[0038] It should be further explained that when folded and locked, the upper upright tube 10 and the lower upright tube 11 are perpendicular to each other. The internal self-locking hanging piece 134 is attached to the upper locking hook 136 of the upper upright tube 10. The lower part of the external handle 131 contacts the outer periphery of the locking hook 136 of the upper upright tube 10 to prevent shaking and to prevent the upper part of the handle 131 from colliding with the upper upright tube 10, thereby protecting the surface of the upper upright tube 10. When unfolded, the maximum rotation of the handle 131 is ≤185°. The front of the handle 131 contacts the lower upright tube 11, limiting the maximum angle. The limit stroke of the handle 131 avoids not locking or excessive operation.
[0039] Example 2
[0040] Reference Figure 4 , Figure 7This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a rigid locking component, including a groove 20. The groove 20 is located inside the end adjacent to the upper riser 10 and the lower riser 11. An internal locking slider 21 is movably connected inside the groove 20. Two second fixing screws 22 are threadedly connected inside the upper riser 10. Two sliding grooves 23 are formed inside the internal locking slider 21 at corresponding positions of the two second fixing screws 22. Two spring set screws 24 are fixedly connected inside the internal locking slider 21. 4. A second tension spring 25 is fixedly connected to the side near the second fixing screw 22. An eccentric shaft top block 26 is fixedly connected to the side of the inner-locking slider 21 near the folding shaft 12. The eccentric shaft top block 26 corresponds to the position of the self-locking component 13. The end of the second tension spring 25 away from the spring top screw 24 contacts the second fixing screw 22. The second fixing screw 22 passes through the sliding groove 23 and is threaded into the inside of the upper tube 10. The front end of the inner-locking slider 21 is provided with two arc-shaped protrusions, and the two arc-shaped protrusions are engaged in the two grooves 20 of the upper tube 10 and the lower tube 11.
[0041] Specifically, the front end of the internal locking slider 21 is provided with two arc-shaped protrusions, which correspond to the two grooves 20 of the upper upright tube 10 and the lower upright tube 11, so that the upper upright tube 10 and the lower upright tube 11 are rigidly locked, thereby improving stability.
[0042] When in use, with the handle 131 positioned between the upper riser 10 and the lower riser 11, the deflection part of the handle 131 presses against the eccentric shaft top block 26. At this time, the two arc-shaped protrusions engage with the two grooves 20 inside the upper riser 10 and the lower riser 11. When folding and locking are required, the self-locking push block 133 is pressed down, causing the self-locking plate 134 to disengage from the locking hook 136. The upper riser 10 is rotated, and while the handle 131 remains in the same position, the upper riser 10 rotates. The upper riser 10 causes the position of the inner locking slider 21 to change. At this time, the contact position between the eccentric shaft top block 26 and the handle 131 changes. The short radius of the handle 131 near the folding shaft 12 gradually approaches the eccentric shaft top block 26, causing the handle 131 to gradually reduce its pressure on the eccentric shaft top block 26. At this time, the second tension spring 25 rebounds, causing the inner locking slider 21 to move linearly backward under the limiting action of the two second fixing screws 22. At this time, the inner locking is achieved. The two arc-shaped protrusions at the front end of the slider 21 disengage from the grooves 20 of the upper and lower risers 10 and 11, allowing the upper and lower risers 10 to fit tightly together. When the upper riser 10 is rotated to a vertical position, the handle 131 is rotated upwards, and the long radius of the handle 131 gradually fits against the eccentric shaft top block 26. This causes the inner locking slider 21 to slide forward through the eccentric shaft top block 26, so that the arc-shaped protrusions at the front end of the inner locking slider 21 are embedded into the grooves 20 of the upper and lower risers 10 and 11, achieving rigid locking. The inner locking slider 21 and the grooves 20 tightly combine the upper and lower risers 10 and 11, improving stability and reliability, and also providing secondary locking for the upper and lower risers 10 and 11. When the riser needs to be unfolded, the inner locking slider 21 slides axially away from the grooves 20, and the upper and lower risers 10 and 11 can rotate relative to each other around the hinge shaft structure, achieving folding and realizing the locking and unlocking functions.
[0043] It should be noted that the front end of the internal locking slider 21 is provided with an arc-shaped convex groove structure, the two rear ends are provided with spring pre-installation holes, and the inside is provided with a screw sliding groove 23.
[0044] It should be noted that the entire device is forged from aluminum alloy, which increases structural strength and reduces weight by 30% compared to existing steel folding structures, thus reducing the overall vehicle load.
[0045] It should be noted that the locking mechanism is built-in, and the folded appearance is smooth and aesthetically pleasing, reducing the risk of scratches and abrasions.
[0046] It should be added that the locking of the self-locking plate 134 and the locking hook 136 also prevents accidental opening caused by the shaking of the upper riser 10 and the lower riser 11. The two locking mechanisms complement each other.
[0047] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
