[0014] This utility model proposes a sliding cover structure 100.

[0015] Please see Figure 1 In one embodiment of the present invention, the sliding cover structure 100 includes a housing 1, a cover 2 and a torsion spring 3. The housing 1 has a through hole 11. The cover 2 is rotatably disposed on the housing 1 to open or close the through hole 11. The two ends of the torsion spring 3 are rotatably connected to the housing 1 and the cover 2 respectively. The torsion spring 3 is configured to provide driving force during the partial stroke of the cover 2 rotating and opening the through hole 11.

[0016] In this embodiment, the sliding cover structure 100 can be applied to scenarios such as aerosol generating devices and toothpick boxes, and can also be applied to boxes with holes, such as boxes with holes for taking out and taking out items. When it is necessary to take out an item, the sliding cover 21 is opened, and after taking out the item, the sliding cover 21 is closed to prevent dirt from entering the box. These scenarios are not limited here. The housing 1 is used to provide support for the entire sliding cover structure 100. The material of the housing 1 is plastic, such as polycarbonate, acrylonitrile-butadiene-styrene copolymer, etc., which are not limited here. The cover 2 opens or closes the through hole 11 by rotating. The cover 2 rotates around a fixed axis, and the driving force of the torsion spring 3 acts on the rotation axis of the cover 2, so that the cover 2 can open or close the through hole 11 around the axis. In one embodiment, the cover 2 is connected to the housing 1 through a hinge shaft, and the cover 2 can rotate around the hinge shaft to open or close the through hole 11; in another embodiment, the cover 2 is connected to the housing 1 through a rotating shaft and a flange. The rotating shaft passes through a flange, which is fixed to the housing 1. The cover 2 is connected to the rotating shaft via the flange. A through-hole 11 provides an interface for user operation. It is understood that the housing 1 has a first rotating hole, one end of the torsion spring 3 is inserted into the first rotating hole, and the cover 2 has a second rotating hole, the other end of the torsion spring 3 is inserted into the second rotating hole. When the cover 2 rotates around the housing 1, both ends of the torsion spring 3 will rotate within the first and second rotating holes respectively. The material of the torsion spring 3 includes, but is not limited to, stainless steel, alloy steel, etc., and is not specified here. It should be noted that, in conjunction with... Figure 5 The movement process of the sliding cover structure 100 provided by this utility model is as follows: When the cover body 2 is turned clockwise, the rotating shaft 211 in the cover body 2 will drive the crank 22 to rotate clockwise. When the crank 22 is in the position of Figure 5 When moving along the middle arc a, the torsion spring 3 accumulates elastic potential energy; when the crank 22 moves to Figure 5 At the intersection of arc a and arc b, the elastic potential energy of torsion spring 3 accumulates to its peak; when crank 22 is in Figure 5 When moving along the middle arc b, the elastic potential energy of the torsion spring 3 is converted into the kinetic energy of the rotating shaft 211, driving the covering part 212 to complete the rotation.

[0017] The sliding cover structure 100 provided by this utility model, through the combined design of a housing 1, a cover 2, and a torsion spring 3, solves the problems of inconvenient operation, poor stability, and short service life of traditional sliding cover structures 100 during opening and closing. Specifically, the housing 1 serves as the basic frame of the entire sliding cover structure 100, and the through hole 11 on it is used to achieve communication or isolation between the inside and the outside. The cover 2 is rotatably mounted on the housing 1, and the through hole 11 is opened or closed by rotation. This design allows users to achieve the opening and closing function with a simple rotation operation, making operation more convenient. The two ends of the torsion spring 3 are rotatably connected to the housing 1 and the cover 2. When the cover 2 rotates, the torsion spring 3 generates an elastic force. This elastic force can assist the opening and closing of the cover 2, making the opening and closing process smoother. At the same time, it can also maintain the stability of the cover 2 in the open or closed state to a certain extent, reducing accidental opening or closing caused by external forces. In addition, the use of the torsion spring 3 can also effectively disperse the stress during the opening and closing process, reduce the risk of component damage caused by frequent operation, and thus extend the service life of the sliding cover structure 100. Furthermore, when the user flicks the cover 2 with their finger, the cover 2 rotates around the housing 1. In the initial stage, the torsion spring 3 is compressed and gradually accumulates elastic potential energy; when the cover 2 rotates more than halfway around the housing 1, the elastic potential energy stored in the torsion spring 3 is converted into the kinetic energy of the cover 2, driving the cover 2 to complete the full stroke rotation. This setup, through the rotational connection and the elastic assistance of the torsion spring 3, allows the user to easily complete the opening and closing action without applying significant force, thus improving the user experience.

[0018] In one embodiment of the present invention, the cover 2 includes a sliding cover 21 and a crank 22. The sliding cover 21 includes a pivot portion 211 and a covering portion 212. The pivot portion 211 is connected to the covering portion 212. The pivot portion 211 rotatably passes through the housing 1 and is rotatably connected to the crank 22. The crank 22 is rotatably connected to the torsion spring 3.

[0019] In this embodiment, combined with Figure 2 The sliding cover 21 is used to open and close the through hole 11. The rotating shaft 211 serves as the rotation center of the sliding cover 21. By transmitting the driving force of the torsion spring 3 to the rotating part, the covering part 212 can rotate around it, thereby realizing the opening and closing of the through hole 11. It can be understood that the covering part 212 and the rotating shaft 211 are made of polyoxymethylene (POM). The connection between the covering part 212 and the rotating shaft 211 includes, but is not limited to, welding, integral molding, etc. The covering part 212 can be understood as a cover plate-like structure, and the rotating shaft 211 can be understood as a rotating shaft rod-like structure. The crank 22 can guide the movement direction of the sliding cover 21, ensuring that the sliding cover 21 moves on the correct movement trajectory. The connection between the crank 22 and the rotating shaft 211 includes, but is not limited to, bolt connection, riveting connection, etc., which are not limited here.

[0020] In one embodiment of the present invention, the covering part 212 is provided with a slot 212a, the slot 212a extends along the rotation direction of the covering part 212, and the housing 1 is provided with a hook 14 on the side surface facing the covering part 212. The hook 14 is provided near the periphery of the through hole 11 and is locked and limited in the slot 212a.

[0021] In this embodiment, combined with Figure 2 To achieve a stable connection, the cover 212 is provided with a slot 212a, and a hook 14 is provided on one side of the housing 1. The design of the slot 212a and the hook 14 ensures a stable connection between the cover 2 and the housing 1, preventing the cover 2 from accidentally loosening or falling off during use. Figure 4 It should be noted that the covering part 212 rotates around the rotating shaft part 211, and its rotation direction is approximately an arc. The hook 14 is provided on one side of the surface of the housing 1 and remains stationary. To avoid interfering with the movement of the covering part 212, the groove 212a of the covering part 212 is provided along the rotation direction of the covering part 212, that is, it extends through along the arc. When the cover 2 rotates, the hook 14 slides along the groove 212a, limiting the rotation angle of the cover 2 and ensuring that the cover 2 stays stably in a specific position. When the cover 2 closes the through hole 11, the hook 14 is fully engaged in the groove 212a, achieving locking; when it is necessary to open the cover 2, a certain force is applied to overcome the friction between the hook 14 and the groove 212a, causing the cover 2 to rotate. It can be understood that the hook 14 and the groove 212a are in clearance fit and will not affect the normal rotation of the cover 2, only playing a limiting role when the cover 2 is tilted up.

[0022] In one embodiment of the present invention, a protruding ridge 212b is provided on the side wall of the card slot 212a near the opening of the card slot 212a, and the hook 14 is limited to the card slot 212a and slides against the protruding ridge 212b.

[0023] In this embodiment, combined with Figure 2 To further enhance connection stability, the design of the protruding ridge 212b increases the contact area and friction between the hook 14 and the slot 212a, ensuring that the cover 2 is more stable in the closed state and less prone to loosening or falling off. Simultaneously, the protruding ridge 212b provides a sliding guide surface for the hook 14, ensuring that the hook 14 slides along a predetermined trajectory within the slot 212a, preventing the hook 14 from shifting or getting stuck during movement. It is understood that the protruding ridge 212b can be designed as an inclined surface. When the hook 14 engages with the slot 212a, the inclined surface provides a guiding effect, allowing the hook 14 to slide more easily into the slot 212a and abut against the protruding ridge 212b.

[0024] In one embodiment of the present invention, the cover 2 further includes a top cover 23, which covers the covering portion 212. The inner peripheral wall of the top cover 23 is provided with a fastener 23a, and the outer peripheral wall of the covering portion 212 is provided with a mating groove 212c. The fastener 23a engages with the mating groove 212c.

[0025] In this embodiment, combined with Figure 2 and Figure 4 It should be noted that, in order to improve the aesthetics of the sliding cover structure 100, a top cover 23 is also provided on the outside of the sliding cover 21. Since the sliding cover 21 is made of POM material, its coating adhesion is poor, and the injection molding appearance is prone to defects. Therefore, a top cover 23 is provided separately on the outside of the sliding cover 21 to improve the aesthetics of the cover body 2. Furthermore, in order to improve the connection stability between the top cover 23 and the sliding cover 21, the top cover 23 is engaged with the mating groove 212c of the covering part 212 by a snap fastener 23a, which enhances the structural stability of the sliding cover 21 and prevents the covering part 212 from loosening or falling off during use. A snap fastener 23a is provided on the inner peripheral wall of the top cover 23. The snap fastener 23a is in the form of an elastic arm or elastic hook with a certain elastic deformation capability. The shape and size of the mating groove 212c match the snap fastener 23a. When the top cover 23 is installed onto the cover portion 212, the snap fastener 23a enters the mating groove 212c through elastic deformation and returns to its original shape after entering the groove, thereby achieving a snap-fit ​​connection. This snap-fit ​​method provides sufficient friction and locking force to ensure a secure connection between the top cover 23 and the cover portion 212.

[0026] In one embodiment of the present invention, the housing 1 has a shaft hole 15, and a protruding ring 12 is provided around the shaft hole 15. A step is formed between the protruding ring 12 and the surface of the housing 1. The cover 2 includes a top cover 23, and a gap is formed between the top cover 23 and the protruding ring 12.

[0027] In this embodiment, combined with Figure 2 and Figure 3 To avoid interference between the cover 2 and the housing 1 when they rotate, the housing 1 is provided with a protruding ring 12 around the shaft hole 15. A step is formed between the protruding ring 12 and the surface of the housing 1, and a gap is formed between the top cover 23 and the protruding ring 12. This can effectively prevent the rotating sliding cover 21 from rubbing against the surface of the housing 1 when the sliding cover 21 is tilted downward, thereby reducing the risk of wear and damage caused by friction.

[0028] In one embodiment of the present invention, the sliding cover structure 100 further includes a sealing ring 4 and a damping layer. The sealing ring 4 is disposed between the housing 1 and the crank 22. The sliding cover 21 includes a rotating shaft portion 211 and is sleeved on the rotating shaft portion 211. The damping layer is disposed around the outside of the sealing ring 4 and abuts against the housing 1 and the crank 22.

[0029] In this embodiment, combined with Figure 2To enhance sealing, a sealing ring 4 is positioned between the housing 1 and the crank 22, effectively preventing dust and liquids from entering the housing 1. Simultaneously, a damping layer surrounds the outer side of the sealing ring 4 and abuts against the housing 1 and crank 22, providing resistance and making the opening and closing of the sliding cover 21 smoother and more responsive, thus improving the user experience. It should be noted that the sealing ring 4 is made of materials including, but not limited to, rubber and silicone, which fill the gap between the two through elastic deformation to form a seal. The number of sealing rings 4 is not limited; it can be one, two, etc. The damping layer is typically a polymer material, such as polyurethane or rubber; in this case, it is damping grease, serving both lubrication and damping functions. Because the damping layer is viscous and the sealing ring 4 is under compression, the damping layer will not leak out. It is understood that the sealing ring 4 is sleeved on the sliding cover 21. In one embodiment, the sealing ring 4 is directly installed on the contact surface between the housing 1 and the crank 22, and the gap between the two is filled by the elastic deformation of the sealing ring 4 to form a seal. In another embodiment, an embedding groove is opened on the contact surface of the housing 1 or the crank 22, and the sealing ring 4 is embedded in the groove to ensure that the sealing ring 4 will not shift after installation. In yet another embodiment, a snap-fit ​​structure is designed on the contact surface of the housing 1 or the crank 22, and the sealing ring 4 is fixed between the housing 1 and the crank 22 by snap-fit. The above-mentioned arrangement is not limited.

[0030] In one embodiment of this utility model, the cover 2 includes a sliding cover 21, the sliding cover 21 includes a rotating shaft portion 211, the housing 1 has a shaft hole 15, the rotating shaft portion 211 passes through the shaft hole 15, the peripheral wall of the shaft hole 15 has a limiting groove 13 arranged in an annular shape, the crank 22 is limited in the limiting groove 13, the crank 22 has a receiving groove 221, the opposite ends of the sealing ring 4 abut against the inner wall of the limiting groove 13 and the bottom wall of the receiving groove 221 respectively; the damping layer abuts against the inner wall of the limiting groove 13 and the bottom wall of the receiving groove 221 respectively.

[0031] In this embodiment, combined with Figure 2 To enhance sealing, the two ends of the sealing ring 4 abut against the inner wall of the limiting groove 13 and the bottom wall of the receiving groove 221, respectively, and fill the gap between them through elastic deformation to form a seal. The damping layer abuts against the inner wall of the limiting groove 13 and the bottom wall of the receiving groove 221, respectively, and provides a certain resistance through the internal friction characteristics of the material, making the opening and closing action of the sliding cover 21 smoother.

[0032] In one embodiment of the present invention, the sliding cover structure 100 further includes a fastener 5. The sliding cover 21 has an installation groove 211a. The fastener 5 passes through the crank 22 and extends into the installation groove 211a, and is threadedly connected to the inner wall of the installation groove 211a.

[0033] In this embodiment, combined with Figure 2 and Figure 4To enhance connection stability, fastener 5 passes through crank 22 and extends into the mounting groove 211a of slide cover 21, where it is threaded into the inner wall of the groove 211a. This ensures a more secure connection between slide cover 21 and housing 1, preventing slide cover 21 from loosening or falling off during use. The type of fastener 5 includes, but is not limited to, screws and bolts. When fastener 5 is tightened, the connection between slide cover 21 and housing 1 is firmly secured, ensuring that slide cover 21 will not loosen during use. The threaded connection provides sufficient friction and locking force to ensure reliable connection.

[0034] This utility model also proposes an electronic device, which includes the sliding cover structure 100 described above. The specific structure of the sliding cover structure 100 is as described in the above embodiments. Since this electronic device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The type of electronic device includes, but is not limited to, aerogel generating devices, and can also be applied to smart toothpick holders, boxes with holes, etc. When the sliding cover structure 100 is applied to an aerogel generating device, the sliding cover 21 is opened when a conductor that needs to be heated is inserted, and closed when the conductor does not need to be heated. This effectively prevents dirt from entering the cavity of the aerogel generating device and contaminating the heated conductor, and also prevents metal substances from entering the cavity through the holes, thus activating the automatic heating program.
