Description

Technical Field

[0001] This utility model relates to a semi-automatic, controllable electric zipper, belonging to the field of zipper technology. Background Technology

[0002] Zippers, as a commonly used detachable connecting component, are widely used in various products such as clothing, bags, tents, and sleeping bags. Their core function is to enable quick closing and separation between two independent components, while ensuring a tight seal and stability after connection. The structure of traditional zippers is a mature system, typically consisting of three core components: two parallel base tapes, each with linearly arranged pairs of teeth (i.e., zipper teeth), and a slider to drive the teeth to engage or disengage. The teeth and base tapes are usually tightly connected using a one-piece molding process or sewing, ensuring the teeth are fixed in position on the tapes. Their working principle is as follows: by manually pushing or pulling the slider, the guide structure inside the slider forces the teeth on both sides of the tape to sequentially engage with their corresponding slots, achieving engagement and closure; operating the slider in the opposite direction disengages the teeth, completing separation.

[0003] Although traditional zippers are widely used in daily life, they still have many shortcomings and deficiencies due to limitations in structural design and operation, as follows:

[0004] Traditional zippers have their teeth fixedly connected to the fabric tape, and there is no active guiding structure during the closing process. When zippers are used on clothing, if the clothing shrinks after washing, the fabric tape stretches due to changes in body shape during wear, or the fabric tape deforms due to lateral external force during use, the teeth on both sides of the fabric tape will become misaligned. Either the teeth cannot be accurately aligned with the grooves, making it impossible to pull up, or even if it is pulled up, the teeth will not mesh properly, and it will break open under slight external force, seriously affecting the user experience and connection reliability.

[0005] Traditional zippers rely entirely on manual operation of the zipper pull, requiring users to precisely grip the pull and move it longitudinally along the fabric strip. When users are in situations where their hands are occupied (such as carrying heavy objects or holding infants), or when their hand function is limited (such as hand injuries or joint diseases like arthritis), it is difficult to smoothly push or pull the zipper pull. The operation is cumbersome and inefficient, failing to meet the needs of semi-automatic or low-manual-reliance usage. Utility Model Content

[0006] This invention provides a semi-automatic, controllable electric zipper to solve the problems in the prior art where the deformation of the fabric tape easily leads to misalignment of the chain teeth, poor reliability of opening and closing, reliance on both hands for opening and closing, and insufficient convenience in special scenarios.

[0007] This utility model provides a semi-automatic controllable electric zipper, which includes a main zipper and a secondary zipper. The main zipper includes a first base tape and a limiting hook, and the secondary zipper includes a second base tape and a limiting component that match the first base tape and the limiting hook.

[0008] The main zipper and the secondary zipper are secured to each other by a fixing component;

[0009] The limiting hook is movably connected to the first base fabric belt through a control component, and the control component drives the limiting hook to rotate circumferentially on the first base fabric belt.

[0010] Preferably, there are multiple limiting hooks, which are linearly arranged on the first base fabric tape. The limiting component includes a limiting plate and a limiting post. The limiting plate is located on both sides of the secondary zipper, and the limiting post is located between the two limiting plates and corresponds to the limiting hook.

[0011] Preferably, the limiting plates on both sides are symmetrically arranged, and there are multiple limiting posts. The multiple limiting posts are linearly arranged between the two limiting plates, and the first base fabric strip is provided with a positioning plate that matches the limiting hook.

[0012] Preferably, there are multiple fixing components, and the multiple fixing components are linearly arranged between the first base fabric strip and the second base fabric strip.

[0013] Preferably, the fixing component includes a first magnet and a second magnet that attracts each other to the first magnet, and the first magnet and the second magnet are fixedly connected to the positioning plate and the limiting plate, respectively.

[0014] Preferably, the positioning plate is provided with a through hole that matches the limiting hook, and the limiting hook is provided with a rotating shaft that passes through the through hole. The limiting hook is movably connected to the through hole through the rotating shaft.

[0015] Preferably, the control component includes a traction rope and a drive component. The traction rope is connected to the first base fabric belt via a traction spring, and the traction rope is connected to the limit hook.

[0016] Preferably, the traction spring is located at the top of the traction rope, and the drive assembly is located at the bottom of the traction rope away from the traction spring. The drive assembly is a drive motor.

[0017] Preferably, the driving component includes a support frame, a pressing cap, and a connecting block. The pressing cap is slidably connected to the support frame. The pressing cap is provided with a connecting block that matches the connecting block. The top of the connecting block can slide between itself and the connecting block. The support frame is provided with a plurality of first limiting blocks. The top of the connecting block can slide between itself and the first limiting blocks.

[0018] Preferably, the support frame is provided with a plurality of first sliding grooves that match the pressing cap, the pressing cap slides along the first sliding groove, the connecting block is provided with a support block that matches the first sliding groove, and the top of the support block can slide correspondingly to the connecting block and the first limiting block.

[0019] The beneficial effects of this utility model are:

[0020] This invention provides a semi-automatic, controllable electric zipper. It actively guides the alignment of the first and second base fabric strips by mutual attraction between multiple first and second magnets, ensuring a smooth closing process. This effectively avoids the misalignment of the chain teeth on both sides when the zipper is deformed due to shrinkage during washing, changes in body shape during wearing, or external pulling, which can cause it to be unable to be pulled up or to break open after being pulled. The drive component drives the traction rope, thereby simultaneously controlling the rotation of multiple limit hooks, realizing the semi-automatic opening and closing of the zipper. This greatly reduces the reliance on hands, especially in scenarios where hands are occupied or hand functions are limited, improving the convenience and efficiency of use.

[0021] In Embodiment 2, the drive component adopts a completely mechanical structure and does not rely on electric drive. Therefore, the zipper can be operated by manually pressing the press cap in any scenario, avoiding the risk of the zipper becoming unusable due to power failure and improving the product's safety and emergency response capabilities.

[0031] 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.

[0032] Example 1

[0033] This utility model proposes a semi-automatic controllable electric zipper, including a main zipper 1 and a secondary zipper 2. The main zipper 1 and the secondary zipper 2 are connected by a fixing component 3. The main zipper 1 includes a first base tape 11 and a limiting hook 12. The secondary zipper 2 includes a second base tape 21 that matches the first base tape 11 and a limiting component 22 that matches the limiting hook 12. There are multiple limiting hooks 12 arranged linearly on the first base tape 11. The limiting component 22 includes a limiting plate 221 and limiting posts 222. The limiting plate 221 is symmetrically arranged on both sides of the second base tape 21 near the first base tape 11. The limiting plate 221 is fixedly connected to the second base tape 21. There are multiple limiting posts 222 arranged linearly between the two limiting plates 221. There are gaps between the multiple limiting posts 222 and between the limiting posts 222 and the second base tape 21.

[0034] The first base fabric strip 11 is provided with a positioning plate 111 that matches the limiting hook 12. The positioning plate 111 is located on both sides of the first base fabric strip 11 and is fixedly connected to the first base fabric strip 11. The positioning plate 111 is provided with a through hole 112 that matches the limiting hook 12. The limiting hook 12 passes through the through hole 112 and is rotatably connected to the positioning plate 111. There are multiple limiting hooks 12, which are linearly arranged on the positioning plate 111.

[0035] There are multiple fixing components 3, which are linearly arranged on the positioning plate 111 and the limiting plate 221. The fixing components 3 are spaced apart from the limiting hooks 12 and the limiting posts 222. Each fixing component 3 includes a first magnet 31 and a second magnet 32. The first magnet 31 is fixedly connected to the positioning plate 111, and the second magnet 32 ​​is fixedly connected to the limiting plate 221. The first magnet 31 and the second magnet 32 ​​attract each other.

[0036] The control component includes a traction rope 4 and a drive component 5. The traction rope 4 is connected to the first base fabric 11 by a traction spring 6. The traction rope 4 is arranged along the longitudinal direction of the first base fabric 11. The traction rope 4 is sequentially fixedly connected to a plurality of limit hooks 12. The drive component 5 is located at the bottom of the traction rope 4 away from the traction spring 6. The drive component 5 is a drive motor. The output shaft of the drive motor is connected to the drive component 5 to drive the drive component 5 to wind up.

[0037] In use, the limiting hook 12 on the first base fabric belt 11 and the limiting component 22 on the second base fabric belt 21 cooperate to fix the zipper. The end of the limiting hook 12 away from the first base fabric belt 11 is hooked onto the limiting post 222. When it is necessary to unzip the zipper, the drive component 5 is activated, causing the drive motor to drive the traction rope 4 to wind up through the output shaft. The traction rope 4 begins to move downwards, simultaneously pulling the traction spring 6. During the downward movement of the traction rope 4, multiple limiting hooks 12 rotate clockwise around the through hole 112, causing the limiting hooks 12 to disengage from the limiting post 222, thereby separating the second base fabric belt 21 from the first base fabric belt 11. When it is necessary to tighten the zipper, the control component begins to move in the opposite direction, and the traction spring 6 begins to drive the traction rope 4 to reset. At this time, the positioning is achieved. The first magnet 31 and the second magnet 32 ​​on the positioning plate 111 and the limiting plate 221 begin to attract each other, thereby locking and fixing the limiting hook 12 and the limiting post 222. The first magnet 31 and the second magnet 32 ​​are linearly arranged on the positioning plate 111 and the limiting plate 221, respectively. The fixing component 3 is spaced apart from the limiting hook 12 and the limiting post 222. The mutual attraction between the multiple first magnets 31 and the second magnets 32 actively guides the alignment of the two sides of the fabric tape, ensuring a smooth closing process. Furthermore, by providing the first magnet 31 and the second magnet 32 ​​between the limiting hook 12 and the limiting post 222, the use of traditional zippers can avoid the misalignment of the chain teeth on both sides when the fabric tape is deformed due to the shrinkage of the clothing during washing, changes in body shape during wearing, or external pulling, which would cause the zipper to be unable to be pulled up or to break open after being pulled and closed.

[0038] Compared to existing designs, the linear arrangement of multiple limiting hooks 12 on the first base fabric 11 ensures even force distribution on the zipper during fixing. Each limiting hook 12 can independently engage with the limiting component 22, increasing the reliability of the fixation. The multiple limiting hooks 12 design avoids the problem of zipper loosening or damage due to excessive local force. Multiple limiting posts 222 are linearly arranged between the two limiting plates 221, and gaps exist between the multiple limiting posts 222 and between the limiting posts 222 and the second base fabric 21, allowing the limiting hooks 12 to smoothly hook onto the limiting posts 222. This also provides space for the limiting hooks 12 to rotate and disengage. The positioning plate 111 provides a stable rotation axis for the limiting hooks 12, enabling the limiting hooks 12 to move smoothly along the traction rope 4. When pulled, the zipper rotates smoothly. Multiple first magnets 31 and second magnets 32 attract each other, actively guiding the first base fabric strip 11 and the second base fabric strip 21 to align, ensuring a smooth closing process. This prevents misalignment of the chain teeth on both sides when the fabric strip deforms due to shrinkage during washing, changes in body shape during wear, or external pulling. When the zipper is tightened, the first magnets 31 and second magnets 32 attract each other, further enhancing the locking and fixing effect between the limit hook 12 and the limit post 222, improving the stability of the zipper. The drive component 5 can simultaneously drive multiple limit hooks 12 to rotate via the traction rope 4, realizing semi-automatic opening and closing of the zipper.

[0039] Example 2

[0040] The difference between this embodiment and the previous embodiment is that the driving component 5 includes a support frame 51, a pressing cap 52, and a connecting block 53. The pressing cap 52 and the connecting block 53 are located inside the support frame 51. The support frame 51 is provided with a first sliding groove 511 and a first limiting block 512 that matches the first sliding groove 511. The first sliding groove 511 and the first limiting block 512 are multiple and arranged circumferentially on the inner wall of the support frame 51. The first limiting block 512 is located on one side of the top of the first sliding groove 511, and the top of the first limiting block 512 is provided with a first inclined surface. The pressing cap 52 is slidably connected to the support frame 51 through the first sliding groove 511. The pressing cap 52 is provided with a first inclined surface. The first slide groove 511 has a matching protrusion, which is slidably connected to the first slide groove 511. The top of the pressing cap 52 is provided with multiple circumferentially arranged connecting blocks 521. The connecting block 53 is provided with multiple supporting blocks 531 that match the connecting block 521. The multiple 531 are arranged circumferentially around the connecting block 53 and correspond to the first slide groove 511. The bottom of the supporting block 531 is provided with a second inclined surface that matches the first inclined surface. The connecting block 521 is provided with a third inclined surface that matches the second inclined surface. The top of the connecting block 53 is fixedly connected to the traction rope 4. The connecting block 53 is connected to the bottom of the first base cloth belt 11 by a compression spring 54.

[0041] During use, the connecting block 53 is in its initial position, and the support block 531 is engaged between multiple first limiting blocks 512. When it is necessary to move the traction rope 4 downward, pressing the pressing cap 52 causes it to slide upward along the first slide groove 511. The pressing cap 52 squeezes the support block 531, causing the connecting block 53 to slide synchronously inside the support frame 51. The compression spring 54 is compressed. When the support block 531 disengages from the first limiting blocks 512... At this time, the support block 531 slides through the second inclined surface and the third inclined surface on the connecting block 521, the connecting block 53 rotates, the pressing cap 52 is released, and the connecting block 53 begins to reset under the action of the compression spring 54. The support block 531 drives the connecting block 53 to slide down along the first slide groove 511. The connecting block 53 drives the traction rope 4 to pull down, and the limiting hook 12 begins to rotate around the through hole 112. The limiting hook 12 separates from the limiting post 222, thereby realizing the first base cloth belt 11, The second base fabric tape 21 separates. When the zipper needs to be tightened, the pressing cap 52 is pressed again, causing the pressing cap 52 to drive the connecting block 53 to move upward along the first slide groove 511. When the support block 531 disengages from the first slide groove 511, the second inclined surface on the support block 531 and the third inclined surface on the connecting block 521 cooperate with each other. The support block 531 begins to slide along the third inclined surface, and the connecting block 53 rotates. The pressing cap 52 is released, and the connecting block 53, under the action of 54, drives the pressing cap 52 and the connecting block 53 to reset. After rotation, the connecting block 53 is engaged between multiple first limit blocks 512 by the support block 531. At the same time, the traction rope 4 moves upward and begins to serve, driving the limit hook 12 to rotate counterclockwise. The limit hook 12 and the limit post 222 cooperate with each other to achieve fixation, thus eliminating the dependence on electricity. It can be operated in any scenario, avoiding the risk of failure due to power failure. The pressing action directly drives the connecting block 53 and the traction rope 4, and the response is faster in emergency situations.

[0042] Compared to existing designs, the drive assembly 5 relies entirely on a mechanical structure to control the opening and closing of the zipper, eliminating the need for electric drive. In any scenario, including power outages, the zipper can be operated manually by pressing the press cap 52, avoiding the risk of the zipper becoming unusable due to power failure and improving its practicality and reliability. The pressing action directly drives the connecting block 53 and the traction rope 4, reducing intermediate transmission links and signal transmission time. In emergencies, such as when the zipper needs to be opened or closed quickly, it can respond rapidly to meet emergency needs. The connecting block 521 and the support block 531 on the connecting block 53 cooperate with each other, using the sliding between inclined planes to achieve force transmission and rotation of the connecting block 53. Utilizing the mechanical principle of inclined planes, the linear motion of the press cap 52 is converted into the rotation and linear motion of the connecting block 53, achieving control of complex movements.

[0043] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
