Description

Technical Field

[0001] The utility model relates to the technology of non-combustion smoking devices, especially to an elastic openable box body structure. Background Art

[0002] An electronic cigarette, also known as an e-cigarette, is mainly used for quitting smoking and replacing cigarettes. It has the same appearance and similar taste as a cigarette. Since an electronic cigarette does not contain harmful components such as tar and suspended particles in a cigarette and produces smoke by heating rather than burning, it has gradually been recognized by everyone. People who love smoking usually carry an electronic cigarette with them. Due to the lack of a portable electronic cigarette case, people usually place the electronic cigarette in their pockets or handbags, which is likely to contaminate the mouthpiece and is very unfavorable for maintaining health.

[0003] To solve this problem, cigarette cases for electronic cigarettes have emerged on the market. Usually, a top cover is provided at the top of the cigarette case. When the smoking device is not in use, the top cover can be opened, and the smoking device can be put into and stored in the chamber of the cigarette case; when the smoking device needs to be used, the top cover can be opened to take out the smoking device from the cigarette case. However, since an electronic cigarette is usually put into the cigarette case after being smoked a few times, the top cover needs to be opened and closed frequently; and the top cover is reset by a spring. After long-term and high-frequency elastic deformation, the spring is prone to fatigue, resulting in the inability to strongly drive the top cover to flip, so that the top cover cannot be completely reset to the inside of the cigarette case, bringing inconvenience to users. In addition, when opening and closing the top cover of such a cigarette case, a gear mechanism with damping needs to be set to achieve the effect of the slow falling of the top cover, but the gear mechanism with damping has a high cost and a poor damping effect. Therefore, the existing cigarette case for an electronic cigarette should be improved to solve the above problems and improve the user experience. Summary of the Utility Model

[0004] In view of this, in view of the deficiencies existing in the prior art, the main purpose of the utility model is to provide an elastic openable box body structure, which forms an automatically resetable box body structure by arranging an auxiliary mechanism with a piston damper, a gear and a spring between the box body and the top cover. The piston damper not only provides damping for the opening and closing process of the top cover, making the opening and closing of the top cover smoother; at the same time, the piston damper provides a reset driving force compensation for the spring. When the reset force of the spring weakens, it can still ensure the complete reset of the top cover, improving the product experience and durability.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A pop-up box structure, which includes a box body and a top cover. The interior of the box body is hollow, and an opening is formed at the top of the box body. The top cover is adapted to the opening. One end of the top cover is pivotally connected to the end of the opening. A pressing portion is formed at the end of the pivotally connected end of the top cover, which can make the other end tilt relative to the opening by pressing downwards. And a receiving groove for accommodating a smoking device is provided on the inner side of the top cover. An auxiliary mechanism for assisting the top cover to flip open and close is provided between the top cover and the box body. The auxiliary mechanism is located on one side of the pressing portion, and it includes a first gear, a second gear, a piston damper and a spring. The first gear is located on the box body, and the second gear is located at the lower end of the top cover and meshes with the first gear. The piston damper is rotatably installed on the box body, and the upper end of the plunger of the piston damper is hinged to the lower end of one side of the pressing portion of the top cover. The spring is connected between the box body and the lower end of one side of the pressing portion of the top cover.

[0007] As a preferred solution: The piston damper includes a pump body and a plunger. The interior of the pump body has a cavity, and an air hole is provided at the lower end of the cavity. The plunger is slidably installed in the cavity, and an oil groove for storing lubricating oil is spirally provided on the outer wall of the plunger.

[0008] As a preferred solution: The second gear is an incomplete gear, which is integrally provided on the lower surface of the end of the top cover pivotally connected to the box body.

[0009] As a preferred solution: A connecting portion is downwardly provided at the hinged end of the top cover and the box body. The upper end of the plunger of the piston damper and the first connecting end of the spring are respectively connected to the connecting portion.

[0010] As a preferred solution: A bracket is provided in the box body. The first gear is located on the bracket. The pump body of the piston damper is rotatably installed on the bracket. The second connecting end of the spring is connected to the bracket. And the first gear is located above the piston damper and the spring.

[0011] As a preferred solution: The bracket includes a base and a support seat integrally provided on the top of the base. The first gear, the piston damper and the spring are all installed on the base. The top cover is rotatably pivotally connected to the support seat.

[0012] As a preferred solution: The connection position of the upper end of the plunger of the piston damper and the connection portion is higher than the connection position of the first connection end of the spring and the connection portion.

[0013] As a preferred solution: A clearance notch is provided between the base and the support seat for the second gear.

[0014] As a preferred solution: A support plate is extended from the pivotally connected end of the top cover to the other end of the top cover. The receiving groove is formed between the support plate and the top cover.

[0015] As a preferred solution: a base is provided at one end where the top cover is pivotally connected to the box body, and the support plate and the second gear are integrally provided on the base.

[0016] Compared with the prior art, the present utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solutions, by providing an auxiliary mechanism having a piston damper, a gear, and a spring between the box body and the top cover to form a box body structure that can automatically reset, the piston damper not only provides damping for the opening and closing process of the top cover, making the opening and closing of the top cover smoother; at the same time, the piston damper provides a reset driving force compensation for the spring, and when the spring reset force weakens, it can still ensure the complete reset of the top cover, improving the product experience and durability. In addition, using a piston damper as the damping component has better effects and lower costs compared to the traditional box body structure with a damping component provided at the gear position; moreover, by adjusting the plunger stroke, cavity size, and pore diameter of the piston damper, different damping effects of the piston damper can be achieved, making the reset stroke speed of the top cover controllable and meeting different reset dynamic requirements.

[0029] The utility model Figures 1 to 9 As shown, a pop-up box structure includes a box body 10 and a top cover 20, wherein:

[0030] The box body 10 is hollow inside, and a strip-shaped opening 11 is formed at the top of the box body 10; the top cover 20 is adapted to the opening 11, and one end of the top cover 20 is pivotally connected to the end of the opening 11, and a pressing portion 21 is formed at the end of the pivoted end of the top cover 20, which can be pressed downward to tilt the other end relative to the opening 11, and a receiving groove 22 for accommodating the smoking article 30 is provided on the inner side of the top cover 20. After the pressing portion 21 applies downward pressure, the other end of the top cover 20 will tilt like a seesaw, so that the smoking article 30 located in the receiving groove 22 is exposed.

[0031] An auxiliary mechanism 40 for assisting the top cover 20 to flip and open and close is provided between the top cover 20 and the box body 10. The auxiliary mechanism 40 is located on one side of the pressing portion 21, and includes a first gear 41, a second gear 42, a piston damping member 43 and a spring 44. The first gear 41 is located on the box body 10, and the second gear 42 is located at the lower end of the top cover 20 and meshes with the first gear 41; the piston damping member 43 can be flipped and installed on the box body 10, and the upper end of the plunger 432 of the piston damping member 43 is hingedly connected to the lower end of one side of the pressing portion 21 of the top cover 20; the spring 44 is connected between the box body 10 and the lower end of one side of the pressing portion 21 of the top cover 20.

[0032] The piston damper 43 includes a pump body 431 and a plunger 432. The interior of the pump body 431 has a cavity 4311 for accommodating the plunger 432, and an air hole 4312 communicating with the outside is provided at the lower end of the cavity 4311. The plunger 432 is slidably installed in the cavity 4311, and an oil groove 4321 for storing lubricating oil is spirally provided on the outer wall of the plunger 432. When the plunger 432 slides in the cavity 4311, the air hole 4312 can serve as an air inlet and outlet channel to reduce the air pressure resistance for the sliding of the plunger 432. While ensuring the smooth sliding of the plunger 432, it has a certain damping effect, making the reset process of the top cover 20 smoother.

[0033] A connecting portion 23 is provided downward at one end where the top cover 20 is hinged to the box body 10. The upper end of the plunger 432 of the piston damper 43 and the first connection end 441 of the spring 44 are respectively connected to the connecting portion 23. Moreover, the connection position of the upper end of the plunger 432 of the piston damper 43 with the connecting portion 23 is higher than the connection position of the first connection end 441 of the spring 44 with the connecting portion 23. This design enables that whether the top cover 20 is pressed to open or reset and rebound, a part of the acting force of the top cover 20 is first transmitted to the plunger 432, reducing the force on the spring 44 and avoiding fatigue damage caused by elastic deformation of the spring 44 due to long-term force. In addition, the acting force is transmitted to the plunger 432 immediately, and the damping generated by the sliding of the plunger 432 in the pump body 431 can offset the impact force when the top cover 20 is reset, making the reset action of the top cover 20 smooth and presenting a dynamic effect of slowly resetting.

[0034] A bracket 12 is provided in the box body 10. In this embodiment, the bracket 12 includes a base 121 and a support seat 122 integrally provided on the top of the base 121; the first gear 41, the piston damper 43 and the spring 44 are all installed on the base 121. Specifically, the first gear 41 is installed on the base 121, and the pump body 431 of the piston damper 43 is rotatably installed on the base 121. The rotatable setting is mainly because when the top cover 20 is flipped open and closed, the piston damper 43 will swing as a whole. Therefore, the piston damper 43 needs to be rotatably installed on the base 121. The second connection end 442 of the spring 44 (torsion spring or tension spring) is also connected to the base 121, and the first gear 41 is located above the piston damper 43 and the spring 44. The top cover 20 is rotatably pivoted on the support seat 122 through a pivot shaft. A clearance notch 123 is provided between the base 121 and the support seat 122 for the rotation of the second gear 42. The second gear 42 is an incomplete gear, which is integrally provided on the lower surface of the end of the top cover 20 pivoted to the box body 10. The number of teeth and the distribution angle of the incomplete gear can be set according to the designed opening amplitude of the top cover 20; during the opening and closing process of the top cover 20, it is flipped relative to the opening 11, and the second gear 42 meshes with the first gear 41 as the top cover 20 flips, and cooperates with the piston damper 43 and the spring 44 to make the opening and closing of the top cover 20 smoother, reflecting the mechanical sense of the action.

[0035] A tray 24 extends from the end of the top cover 20 pivoted to the box body 10 to the other end. The accommodation groove 22 is formed between the tray 24 and the top cover 20. It should be noted that the accommodation groove 22 can also be in the form of directly integrally providing a jack below the top cover 20, which can be specifically designed according to needs. A base 25 is provided at the end of the top cover 20 pivoted to the box body 10. The tray 24, the second gear 42 and the connecting portion 23 are all integrally provided on the base 25. The integrated design can make the component structure more stable, while reducing the part assembly process and improving the assembly efficiency.

[0036] The working principle of the box body structure is as follows: When opening the box body structure, downward force can be applied at the pressing part 21. The other end of the top cover 20 will tilt upward to expose the smoking device 30, and then the smoking device 30 can be removed at this time. When closing the box body structure, release the pressing part 21. Driven by the elastic restoring force of the spring 44, the pressing part 21 drives the entire top cover 20 to flip upward, and the plunger 432 of the piston damping member 43 moves obliquely upward accordingly. On the one hand, it provides a certain damping for the reset of the top cover 20 to make the closing action of the top cover 20 proceed slowly. On the other hand, the plunger 432 has a certain inertia force when moving obliquely upward. When the restoring force of the spring 44 gradually weakens, the inertia force of the plunger 432 moving obliquely upward will bring a force compensation to the restoring deformation of the spring 44, so that the top cover 20 is completely reset and closed in the opening 11. During the process of opening and closing the box body structure, the first gear 41 and the second gear 42 always move with the flipping of the top cover 20, so that the opening and closing process of the top cover 20 is stable and has a certain mechanical effect.

[0037] It should be noted that the box body structure is not limited to being a container for electronic cigarettes. It can also be applied in other scenarios that require popping open and automatically closing for storage, such as pen cases, cosmetic cases, etc. There are many applicable scenarios and it has a wide range of uses.

[0038] The design focus of the present utility model is to form an automatically resetting box body structure by arranging an auxiliary mechanism with a piston damping member, gears and a spring between the box body and the top cover. The piston damping member not only provides damping for the opening and closing process of the top cover, making the opening and closing of the top cover smoother; at the same time, the piston damping member provides a restoring driving force compensation for the spring. When the restoring force of the spring weakens, it can still ensure the complete reset of the top cover, improving the product experience and durability. In addition, using the piston damping member as the damping component has a better effect and lower cost compared with setting a damping member at the gear position in the traditional box body structure; moreover, by adjusting the plunger stroke, cavity size and pore diameter of the piston damping member, different damping effects of the piston damping member can be achieved, making the reset stroke speed of the top cover controllable to meet different reset dynamic requirements.

[0039] The above is only a preferred embodiment of the present utility model, and does not impose any limitation on the technical scope of the present utility model. Therefore, any minor modification, equivalent change and modification made to the above embodiments according to the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
