[0002] As a peripheral device of a computer, the mouse can increase the convenience of the user. However, most mice are now relatively large and cannot be folded, making them inconvenient to carry. In particular, forcing a mouse into a laptop bag may cause damage to the mouse or other computer-related equipment. In order to facilitate carrying a mouse, users usually hope to reduce the size of the mouse as much as possible. However, because the mouse is usually ergonomically designed according to the human hand to improve the user's comfort, if the size of the mouse is reduced too much, the user's comfort will also decrease. Therefore, it is necessary to design a foldable mouse to meet the user's requirement for easy carrying.

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] like Figure 1-Figure 8 As shown, an external foldable mouse comprises a bottom plate 1, a housing 3 is fixedly and sealedly connected to the upper end of the bottom plate 1, a power supply 8 and a control circuit are fixed inside the housing 3, and a cover 5 is sealedly sleeved on the housing 3. The cover 5 is connected to the bottom plate 1 through a spring 7. Specifically, a first retaining ring 4 is fixed to the outer side of the upper end of the housing 3, and the first retaining ring 4 is in sliding and sealing contact with the inner edge of the cover 5, and a second retaining ring 6 is fixed to the lower end of the cover 5, and the second retaining ring 6 is in sliding contact with the outer edge of the housing 3.

[0027] When the pressure in the housing 3 increases, the cover 5 can move upward. A gas charging and discharging unit is installed at the rear end of the bottom plate 1, and the gas charging and discharging unit is communicated with the interior of the housing 3.

[0028] The inflation and deflation unit includes a reversible air pump 9 fixed to the rear end of the bottom plate 1 . A first channel 10 is provided on the bottom plate 1 . The air outlet of the reversible air pump 9 is connected to the interior of the housing 3 through the first channel 10 .

[0029] A plurality of protrusions are processed at the front end of the bottom plate 1, and a circular cavity 17 is opened in each protrusion. The plurality of circular cavities 17 are arranged concentrically, and a first rotating shaft 19 concentric with the circular cavity 17 is rotatably and sealably connected to the protrusion, and the first rotating shaft 19 is connected to the protrusion through a torsion spring. Specifically, one end of the torsion spring is fixedly connected to the first rotating shaft 19, and the other end of the torsion spring is fixedly connected to the bottom plate 1. The elastic force of the torsion spring is greater than the elastic force of the spring 7.

[0030] One end of the first rotating shaft 19 extends into the circular cavity 17, and a fixed plate 18 is fixedly and sealedly connected in the lower end of the circular cavity 17, and the fixed plate 18 is rotatably and sealedly connected with the first rotating shaft 19. A rotating plate 20 is fixed at the rear end of the first rotating shaft 19 in the circular cavity 17, and the rotating plate 20 is in sealing contact with the inner wall of the circular cavity 17 where it is located, and a sealed cavity is formed between the rotating plate 20 and the fixed plate 18 in the circular cavity 17, and the sealed cavity is connected with the inside of the housing 3. Specifically, a second channel 21 is opened at the front end of the bottom plate 1, and the sealed cavity is connected with the inside of the housing 3 through the second channel 21.

[0031] A rotating frame 22 is fixed on each of the first rotating shafts 19 , and the rotating frame 22 is fixedly connected to the upper cover 12 . A plurality of rotating frames 22 are fixedly connected via a second rotating shaft 23 , and a roller module 24 is installed on the second rotating shaft 23 . A long groove corresponding to the roller module 24 is opened on the cover body 5 .

[0032] The lower ends of the upper covers 12 on both sides of the cover body 5 are fixed with limit plates 11, which are in sliding contact with the outer side of the cover body 5. The upper end of the bottom plate 1 below the upper cover 12 is fixed with a protective cover 2, and the limit plates 11 are located inside the protective cover 2.

[0033] The left and right sides of the front end of the upper cover 12 are respectively fixed with a left key plate 13 and a right key plate 14, both of which are elastic, and the left key plate 13 and the right key plate 14 are respectively fixed with a left key module 15 and a right key module 16 on the bottom plate 1 below the left key plate 13 and the right key plate 14. The left key module 15, the right key module 16, the roller module 24, the power supply 8, the reversible air pump 9 and the control circuit are electrically connected.

[0034] When the mouse is unfolded, the reversible air pump 9 is started to inflate the shell 3. After the air pressure in the shell 3 increases, the cover 5 and the second retaining ring 6 move upward, and the spring 7 is stretched. When the cover 5 moves upward, the upper cover 12, the first rotating shaft 19, the rotating plate 20, the limit plate 11 and the rotating frame 22 rotate around the axis of the first rotating shaft 19, and the torsion spring is compressed. When the first retaining ring 4 and the second retaining ring 6 come into contact, the shell 3 stops moving upward, and then the reversible air pump 9 is turned off to use the mouse.

[0035] During use, when the rear end of the upper cover 12 needs to continue to rotate upward, the reversible air pump 9 is started to continue to inflate the shell 3. Since the first baffle ring 4 and the second baffle ring 6 are in contact, the shell 3 cannot continue to move upward. The rotating plate 20 will drive the first rotating shaft 19, the rotating frame 22 and the upper cover 12 to rotate, and the torsion spring will continue to be compressed. The inclination angle of the upper cover 12 can be adjusted according to the needs of the user, thereby adjusting the palm support strength of the rear end of the upper cover 12 on the user.

[0036] When the mouse needs to be folded, the reversible air pump 9 is turned on to pump out the air in the housing 3. Under the elastic force of the spring 7 and the torsion spring, the cover 5 and the upper cover 12 are restored. When the lower end of the limit plate 11 contacts the upper end of the bottom plate 1, the mouse is folded. At this time, the volume of the mouse becomes smaller and it is convenient to carry.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
