[0002] The cloud printer is favored by many users because of its remote printing function. In order to improve the portability of the user, the paper cover of the cloud printer usually adopts an automatic pop-up structure. However, when the paper cover is automatically popped up, a large impact force will be generated when reaching the final stop position due to the mass of the paper cover and the pop-up speed, which not only causes the paper cover to vibrate back and forth, but also collides with the printing host, affecting the user's experience.

[0003] In the prior art, in order to solve the problem of impact force, a professional damper is arranged in the cloud printer. The damper can effectively buffer the impact force after the paper cover is popped up through the internal damping mechanism, thereby avoiding the collision and back-and-forth vibration of the paper cover with the printing host. However, the professional damper has a large volume and occupies a large space, thereby increasing the weight of the printer.

[0032] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0033] The present application provides a printing device for reducing the impact force after the paper cover is opened. The specific implementation process of the present application is described as follows.

[0034] Please refer to Figures 1 to 6 The printing device provided by the present application comprises:

[0035] The printer body support 01, the paper cover 02, the elastic member and the damping structure; the paper cover 02 is arranged on the printer body support 01, the first end of the paper cover 02 is connected with one side of the printer body support 01, and the second end of the paper cover 02 can rotate around the connection between the first end and the printer body support 01; the elastic member is arranged between the paper cover 02 and the printer body support 01, and the elastic member is used to provide elastic force for opening the paper cover 02; the damping structure comprises a first interference body arranged on the paper cover 02 and a second interference body arranged on the printer body support 01, and the second interference body is used to interfere with the first interference body when the paper cover 02 is opened.

[0036] The main printing part, such as a print head, an ink cartridge, a paper feeding system, etc., is arranged in the printer body support 01. The paper cover 02 is connected to the printer body support 01. The opening and closing of the paper cover 02 is achieved by a flip type. Specifically, the first end of the paper cover 02 is connected to one side of the printer body support 01 by a hinge, a slide rail or other rotatable connection mode. When the paper cover 02 is opened or closed, the second end of the paper cover 02 can rotate around the connection between the first end and the printer body support 01.

[0037] To open the paper cover 02 on the printer body support 01, an elastic member is arranged between the paper cover 02 and the printer body support 01. Under the action of the elastic force provided by the elastic member, the second end of the paper cover 02 rotates around the connection between the first end and the printer body support 01, thereby achieving automatic opening of the paper cover 02. The elastic member can be a spring, an elastic band or the like. The specific embodiments are not limited herein, and the actual implementation is used as a reference.

[0038] The damping structure provides a buffering and deceleration effect in the opening process of the paper cover 02 through the interaction of the first interference body and the second interference body. The first interference body is arranged on the paper cover 02, and the second interference body is arranged on the printer body support 01. The positions of the first interference body and the second interference body correspond to each other, thereby ensuring that when the first interference body and the second interference body interfere with each other, sufficient friction can be generated to slow down the opening speed of the paper cover 02.

[0039] In the present embodiment, the damping structure is composed of the first interference body arranged on the paper cover 02 and the second interference body arranged on the printer body support 01. The positions of the first interference body and the second interference body correspond to each other. During the opening process of the paper cover 02, the first interference body and the second interference body interfere with each other, and the mutual interference generates friction, thereby slowing down the opening speed of the paper cover 02, reducing the impact force after the paper cover 02 is opened, and avoiding the impact and reciprocating vibration between the paper cover 02 and the printer body support 01. In addition, the damping structure occupies a small position, and compared with the existing professional damper, the damping structure can reduce the occupied space and the overall weight of the printer.

[0040] In an optional embodiment, the first end of the paper cover 02 is provided with a support leg 04. One side of the support leg 04 is provided with a rotating shaft 07. The printer body support 01 is provided with a connecting plate 05. The connecting plate 05 is provided with a rotating shaft hole 06, and the rotating shaft 07 is connected in the rotating shaft hole 06. The first interference body is arranged on the support leg 04, and the second interference body is arranged on the connecting plate 05. When the support leg 04 rotates around the rotating shaft 07, the first interference body and the second interference body interfere with each other.

[0041] The connection between the paper cover 02 and the printer body support 01 is realized through the connection between the supporting leg 04 and the connecting plate 05. The connecting plate 05 is provided with a rotating shaft hole 06, and the supporting leg 04 is provided with a rotating shaft 07. The rotating shaft 07 is located in the rotating shaft hole 06 and can rotate in the rotating shaft hole 06, so that the supporting leg 04 can rotate freely around the rotating shaft 07.

[0042] The first interference body is arranged on the supporting leg 04, and the second interference body is arranged on the connecting plate 05. The positions of the first interference body on the supporting leg 04 correspond to the positions of the second interference body on the connecting plate 05. When the supporting leg 04 rotates around the rotating shaft 07 (rotation in the process of opening the paper cover 02), the first interference body and the second interference body interfere with each other, thereby improving the friction between the supporting leg 04 and the connecting plate 05.

[0043] In the embodiment, two supporting legs 04 are arranged on the paper cover 02, and two connecting plates 05 are correspondingly arranged in the printer body support 01. The positions of one supporting leg 04 correspond to the positions of one connecting plate 05. One first interference body is arranged on each supporting leg 04, and one second interference body is arranged on each connecting plate 05.

[0044] Please continue to refer to Figure 3 With Figure 4 In an optional embodiment, the first interference body is a convex block 08, and the second interference body is a groove. The convex block 08 is arranged on the outer periphery of the rotating shaft 07, and the groove is arranged beside the rotating shaft hole 06. The groove is provided with an adjacent bottom surface 10 and a first inclined surface 11. The convex block 08 is located in the groove, so that when the paper cover 02 is opened, the convex block 08 moves from the bottom surface 10 to the first inclined surface 11.

[0045] The rotating shaft 07 is arranged in the rotating shaft hole 06, and at this time, the convex block 08 is arranged in the groove. There is a slope on the first inclined surface 11. The direction from the bottom surface 10 to the first inclined surface 11 is uphill, and the direction from the first inclined surface 11 to the bottom surface 10 is downhill. In the embodiment, when the paper cover 02 is in the process of opening, the convex block 08 rotates with the rotating shaft 07 and moves from the bottom surface 10 to the first inclined surface 11, which is in a climbing state. At this time, the convex block 08 and the first inclined surface 11 are gradually pressed, thereby improving the interference degree between the convex block 08 and the first inclined surface 11, that is, improving the friction, achieving the effect of slowing down the opening speed. On the contrary, in the closing process, the convex block 08 moves from the first inclined surface 11 to the bottom surface 10, and the interference degree between the convex block 08 and the first inclined surface 11 gradually decreases, that is, the friction is reduced, and the closing process is realized easily.

[0046] In the opening process, the supporting leg 04 is deformed outwardly under the action of the first inclined surface 11, and the convex block 08 on the supporting leg 04 extrudes the first inclined surface 11, thereby increasing the friction.

[0047] In an alternative embodiment, the convex 08 is provided with a second slope on the side facing the first slope 11. In this embodiment, the second slope is also provided on the convex 08, and matches the first slope 11. During the opening and closing of the cover, the first slope 11 moves on the second slope.

[0048] In an alternative embodiment, the first slope 11 and the second slope are respectively provided with a wear-resistant layer. In this embodiment, the wear-resistant layer is provided on the two slopes, which can improve the durability of the first slope 11 and the second slope, and improve the service life. The wear-resistant layer can be made of ceramic material, high polymer wear-resistant material, metal alloy, etc.

[0049] In an alternative embodiment, the convex 08 and the foot 04 are integrally formed, and the convex 08 is attached to the shaft 07. In this embodiment, the groove is adjacent to the shaft hole 06, and extends outward from the shaft hole 06. The convex 08 extends outward from the shaft 07, and the position of the convex 08 corresponds to the position of the groove.

[0050] In an alternative embodiment, the elastic member is a torsion spring 03, the foot 04 is provided with a fixed shaft 16 on the side away from the shaft 07, the middle position of the torsion spring 03 is sleeved on the fixed shaft 16, and the two ends of the torsion spring 03 are respectively abutted on the foot 04 and the printer body support 01.

[0051] In this embodiment, the shaft 07 and the fixed shaft 16 are respectively located on the two sides of the foot 04, the shaft 07 is inserted into the shaft hole 06, the fixed shaft 16 extends outward from the other side of the foot 04 away from the shaft 07, the middle position of the torsion spring 03 is sleeved on the fixed shaft 16, one end of the torsion spring 03 is abutted on the foot 04, and the other end is abutted on the printer body support 01 (the connecting plate 05).

By providing the extension 14 and the second clamping groove 13, the torsion spring 03 can be prevented from being randomly detached from the fixed shaft 16.

[0054] Please continue to refer to Figure 6 In an alternative embodiment, the fixed shaft 16 is provided with a stopper 15 at one end away from the leg 04. In this embodiment, the provision of the stopper 15 can further restrict the torsion spring 03 from disengaging from the fixed shaft 16.
