As shown in FIGS. 1-3 , the mouse provided in this embodiment includes a mouse body A, an upper casing 3 and an ejection mechanism 4 . Wherein, a cavity is formed inside the main body A of the mouse for accommodating various electronic components. In one embodiment, the main body A of the mouse includes a lower case 1 and a middle frame 2, the lower case 1 is formed into a pot-shaped structure, and the middle frame 2 is covered on the lower case 1 to form an accommodating cavity for storing various electronic components. Components are set internally. Simultaneously, the mouse also includes commonly used components such as the scroll wheel 5 . Further, the shape of the upper case 3 and the middle frame 2 are matched with each other, and is covered on the middle frame 2 to close the whole structure of the mouse, for example, the upper case 3 closes the battery compartment (not shown in the figure). In this embodiment, the upper casing 3 is popped up by the pop-up mechanism 4, so that operations such as maintenance and battery replacement can be performed conveniently.

As shown in FIG. 2 , the pop-up mechanism 4 includes a magnetically conductive sheet 41 , a driving element 42 , a first magnet 43 and a second magnet 44 . Wherein, as shown in FIGS. 2-4 , the first magnet 43 is fixed on the middle frame 2 and located below the magnetically conductive sheet 41 , and the second magnet 44 is fixed on the upper case 3 and located above the magnetically conductive sheet 41 . It should be noted that the first magnet 43 is opposite to the second magnet 44 with the same pole, and the magnetic guide sheet 41 between the first magnet 43 and the second magnet 44 is provided with a first escape hole 411, and the first avoidance hole 411 The size can be set as needed.

At this moment, the first magnet 43 and the second magnet 44 all produce an attractive force between the magnetically conductive sheet 41, which not only eliminates the repulsive force influence between the first magnet 43 and the second magnet 44, but also allows the second magnet 44 to drive The upper case 3 is attracted, thus increasing the assembly stability of the upper case 3 to a certain extent.

On the other hand, as shown in FIG. 13 , when the driving element 42 drives the magnetically conductive sheet 41 to move to the second position, the first avoidance hole 411 exposes the first magnet 43 and the second magnet 44, that is, the first avoidance hole 411 is located at When the first magnet 43 and the second magnet 44 are in the middle position, the second magnet 44 is acted on by the repulsive force again, and drives the upper casing 3 to bounce off the middle frame 2 . At this time, the upper case 3 is in an open state. Thus, the user of the mouse only needs to operate the drive element 42 to open the upper casing 3 under the magnetic force of the magnet, so that subsequent maintenance and battery replacement can be performed.

Furthermore, the buckle 4211 is configured to be matedly connected with the buckle 31 through the second escape hole 211 . Specifically, when the user of the mouse drives the connecting member 421 through the button 422 , the buckle 4211 can be driven to move through the second escape hole 211 , so that the buckle 4211 can break away from the buckle 31 or be buckled with the buckle 31 .

As shown in FIG. 8 , in one embodiment, the upper surface of the connecting member 421 is recessed to form an accommodating groove 4212 . It is easy to understand that the shape and size of the accommodating groove 4212 match the magnetically conductive sheet 41 , and the magnetically conductive sheet 41 is disposed in the accommodating groove 4212 . Thus, when the user of the mouse drives the connecting member 421 through the button 422 , the magnetically conductive sheet 41 in the accommodating groove 4212 can follow the connecting member 421 to move.

Further, as shown in FIG. 8 , the connecting member 421 is provided with a through hole 4213 penetrating through the bottom of the accommodating groove 4212 . When the magnetic conductive sheet 41 is arranged in the receiving groove 4212 , the first magnet 43 can be arranged under the magnetic conductive sheet 41 through the through hole 4213 .

Further, as shown in FIG. 9 , an accommodating platform 451 is formed on the supporting member 45 , and the first magnet 43 is fixed on the accommodating platform 451 . It should be noted that the accommodating platform 451 is disposed toward the connecting member 421 and protrudes into the through hole 4213 . Thus, the first magnet 43 fixed on the accommodating platform 451 can be disposed under the magnetically conductive sheet 41 . As an optional implementation manner, an accommodating cavity with an upper opening is formed on the accommodating platform 451 , and the first magnet 43 is disposed in the accommodating cavity through the opening.

As shown in FIGS. 2-4 , in one embodiment, the driving element 42 further includes a reset member 423 . Specifically, both ends of the reset member 423 abut against the supporting member 45 and the connecting member 421 respectively. It should be noted that the reset member 423 includes a spring or an elastic member made of elastic material such as rubber. In this embodiment, after the user of the mouse presses the button 422, the connecting member 421 is driven to move, so that the buckle 4211 is disengaged from the buckle 31 and the first escape hole 411 is located in the middle of the first magnet 43 and the second magnet 44, and at the same time The movement of the connecting part 421 causes the reset part 423 to be compressed. When the user of the mouse releases the button 422 , the connecting member 421 can drive the button 422 back to the initial position under the elastic force of the reset member 423 .

As shown in FIG. 4 and FIG. 8 , in one embodiment, the end of the buckle 4211 is formed as a slope inclined downward. Specifically, when the user of the mouse needs to close the upper casing 3 , the connecting member 421 has returned to the original position due to the function of the reset member 423 . At this time, the user buckles the upper housing 3 downwards, and the buckle 31 can abut against the slope at the end of the buckle 4211 , so that the driving connecting member 421 can be moved away from the button 422 through the slope. When the upper casing 3 is completely closed, the clasp 31 no longer exerts any force on the inclined surface, so that the connecting piece 421 can return to the original position under the action of the reset piece 423 , so that the buckle 4211 is snapped into the clasp 31 . Therefore, the user only needs to press down the upper casing 3 to close the upper casing 3 , and the operation is simple and convenient.

Further, as shown in FIG. 8 , the connecting member 421 is provided with a positioning post 4214 , and the reset member 423 is sleeved on the positioning post 4214 . It is easy to understand that the positioning post 4214 can prevent the reset member 423 from shifting when it is compressed or rebounded, so as to ensure that the driving element 42 can continue to work normally. As an optional implementation, the support member 45 is provided with a sixth avoidance hole 452, and the position size of the sixth avoidance hole 452 matches the positioning column 4214, so that the connecting member 421 is driven toward the support member 45 by the button 422 When moving, the positioning post 4214 can pass through the sixth avoidance hole 452 , so as to ensure that the driving element 42 can work normally.

As shown in conjunction with FIGS. 2-4 and FIG. 10 , in one embodiment, the ejection mechanism 4 further includes a non-magnetic support piece 46 .
