In this embodiment, the sliding member 310 can drive the foot pad 200 to change between the first state and the second state through the action of the first elastic member 320 and the limiting member 400 on the sliding member 310, so that the user can adjust the friction force between the foot pad 200 and the working plane as required, thereby improving the user experience.

Further, the first elastic member 320 is a spring, the sliding member 310 is provided with an assembly hole 311 for installing the spring, a limiting column 312 is convexly arranged on the bottom wall of the assembly hole 311, the spring is sleeved on the limiting column 312, the spring can be limited from shaking through the limiting column 312, and the spring extends out of the assembly hole 311 and abuts against the bottom wall of the sliding groove 102.

It should be noted that the spring may be replaced by other elastic bodies, such as elastic rubber or elastic rope.

Through above-mentioned first elastic component 320, when pressing the button of mouse, first elastic component 320 can be in certain extent elastic activity, comfort when can improving the user and use the mouse, can also improve the science and technology sense of mouse.

Further, the sliding member 310 includes a first part 313 slidably disposed in the mounting hole 101 and a second part 314 integrally formed with the first part 313, the second part 314 is slidably disposed in the sliding slot 102, specifically, the second part 314 is mounted in the slot 111 on the base 110, the first part extends into the mounting hole 101, a limiting step surface 315 is formed at a connection position of the second part 314 and the first part 313, the limiting step surface 315 can limit the second part 314 from falling out of the mounting hole 101, specifically, the slot 111 is communicated with the mounting hole 101, the limiting step surface 315 can abut against a bottom wall of the slot 111 connected with the mounting hole 101, so as to limit the second part 314 from falling out of the mounting hole 101, and the foot pad 200 is abutted against the first part 313.

Specifically, when the foot pad 200 is pressed, the foot pad 200 is transformed from the first state to the second state, and when the foot pad 200 is in the second state, a gap is formed between the limiting step surface 315 and the inner wall of the housing 100, and a portion of the limiting member 400 can move into the gap to limit the foot pad 200 from being transformed from the second state to the first state.

Further, the limiting member 400 includes a metal spring plate 410, a button 420, and a second elastic member 430, the housing 100 is provided with a central hole 112 for installing the button 420, specifically, the central hole 112 is formed by enclosing the base 110 and the upper cover 120, the central hole 112 is communicated with the sliding slot 102, the button 420 is movably disposed in the central hole 112, the metal spring plate 410 is disposed on the button 420, when the foot pad 200 is in the second state, the metal spring plate 410 may partially extend into the gap in a natural state, when the foot pad 200 is in the first state, a gap may not be formed between the limiting step surface 315 and the inner wall of the housing 100, so that the limiting member 400 cannot limit the movement of the sliding member 310, when the button 420 is pressed to the pressed state, the metal spring plate 410 may be separated from the gap, so that when the foot pad 200 needs to be restored from the second state to the first state, only the button 420 needs to be pressed to the pressed state, and when the button 420 is released, the second elastic member 430 can drive the button 420 to be restored from the pressed state to the ejected state, so that preparation for next pressing of the button 420 can be made. In this embodiment, through the cooperation of the foot pad 200 and the button 420, the foot pad 200 can be conveniently pressed to the second state and the foot pad 200 can be conveniently restored to the first state from the second state, which is convenient for the user to operate.

To further enhance the user experience and to further enable the composite foot pad 10 to accommodate more types of work surfaces, in one embodiment, the thickness of the portion of the button 420 extending out of the central aperture 112 in the ejected position is not greater than the thickness of the portion extending out of the mounting aperture 101 when the foot pad 200 is in the first position, and the mounting aperture 101 and the central aperture 112 are formed in the same surface of the housing 100. When the thickness of the portion of the button 420 extending out of the central hole 112 is less than the thickness of the portion of the footpad 200 extending out of the mounting hole 101 when the footpad 200 is in the first state, the button 420 does not directly contact the working plane, and when the thickness of the portion of the button 420 extending out of the central hole 112 is equal to the thickness of the portion of the footpad 200 extending out of the mounting hole 101 when the footpad 200 is in the first state, the button 420 can serve as a footpad 200 of another material, thereby improving the adjustability.

Referring to fig. 2, in another embodiment, the central hole 112 is a circular hole, the button 420 is cylindrical, the button 420 is rotatably connected to the metal dome 410 along a central axis thereof, a mounting groove 422 is formed on a side of the button 420 facing away from the metal dome 410, the composite foot pad 10 further includes a cylindrical ball 600, the cylindrical ball 600 is rotatably mounted in the mounting groove 422 around the central axis thereof, a thickness of the cylindrical ball 600 extending beyond the central hole 112 is not greater than a thickness of the foot pad 200 extending out of the mounting hole 101 when the foot pad 200 is in the first state, a thickness of the cylindrical ball 600 extending beyond the central hole 112 is not less than a thickness of the foot pad 200 extending out of the mounting hole 101 when the foot pad 200 is in the second state, and the mounting hole 101 and the central hole 112 are formed on a same surface of the housing 100. In this embodiment, because centre bore 112 is the circular port, button 420 is cylindricly to can make things convenient for button 420 to do the rotation of arbitrary angle relative to centre bore 112, because button 420 extends its central axis and rotationally connects on metal shrapnel 410, thereby can rotate button 420 according to user's demand, thereby adjust the angle of installing the cylinder ball 600 in mounting groove 422. Since the thickness of the cylindrical ball 600 extending beyond the central hole 112 is not greater than the thickness of the foot pad 200 extending beyond the mounting hole 101 when the foot pad 200 is in the first state, and the thickness of the cylindrical ball 600 extending beyond the central hole 112 is not less than the thickness of the foot pad 200 extending beyond the mounting hole 101 when the foot pad 200 is in the second state, the foot pad 200 plays a major role of support when the foot pad 200 is in the first state, and the cylindrical ball 600 plays a role of support together with the foot pad 200 when the foot pad 200 is in the second state, in this case, when the mouse is moved in the axial direction of the cylindrical ball 600, and it is also sliding friction that the mouse is moved in the axial direction of the cylindrical ball 600, since the cylindrical ball 600 is in line contact with the pad supporting the mouse only, the mouse pad is usually a soft pad, therefore, part of the cylindrical ball 600 is pressed in the mouse pad to cause the increase of the friction force, but when the mouse moves towards the direction vertical to the axis of the cylindrical ball 600, the cylindrical ball 600 moves in a rolling way, the friction force of the rolling movement is far smaller than that of the sliding friction force, so that when a user needs to reduce the friction force in a certain direction and improve the friction force in another direction, the composite foot pad 10 in the embodiment can be used for realizing the purpose, for example, when a game is operated, higher requirements are put on the mouse foot pad 200 and the mouse pad, particularly professional players, for this reason, the mouse foot pad 200 can be further designed, for example, in a state that the mouse needs to turn around and aim transversely for many times, the mouse foot pad 200 can provide smaller resistance to the transverse movement and larger resistance to the longitudinal movement; at this time, the foot pad 200 can be pressed to the second state, and the button 420 is rotated to adjust the axial direction of the cylindrical ball 600 to be parallel to the longitudinal direction (i.e., the front-back direction of the movement of the mouse), so that the above-mentioned game requirements of rapid turning and transverse aiming can be satisfied. When the mouse moves forward and backward more and turns to a smaller body, the mouse foot pad 200 needs to move longitudinally to generate smaller resistance; at this time, the foot pad 200 can be pressed to the second state, and the button 420 is rotated to adjust the axial direction of the cylindrical ball 600 to be parallel to the transverse direction (i.e. the left and right directions of the movement of the mouse), so that the game requirement of more forward and backward movement can be met. Or the resistance of the mouse foot pad 200 in each direction is smaller under the conditions of forward and backward traveling, leftward and rightward traveling and turning, at the moment, the foot pad 200 can be restored to the first state, and the resistance in each direction is basically consistent, so that the game requirements of forward and backward traveling, leftward and rightward traveling and turning are met.

In one embodiment, the metal dome 410 includes a fixing ring 411 connected to the button 420, an elastic arm 412 integrally formed with the fixing ring 411, and a position-limiting portion 413 formed at an end of the elastic arm 412, wherein in the second state, the position-limiting portion 413 can extend into the gap under the action of the elastic arm 412, and when the button 420 is pressed, the elastic arm 412 can drive the position-limiting portion 413 to be removed from the gap.

Preferably, the position-limiting portion 413 and the fixing ring 411 are both parallel to the horizontal plane, and the elastic arm 412 and the position-limiting portion 413 form an obtuse angle. Because the elastic arm 412 and the limiting part 413 are arranged at an obtuse angle, if the sliding part 310 does not abut against the fixing ring 411 in the radial direction, the elastic arm 412 can be ejected outwards in the radial direction of the fixing ring 411 in a natural state, so that when the foot pad 200 is pressed in the direction opposite to the first direction a to enable the foot pad 200 to be in the second state, a gap is formed between the limiting step surface 315 and the inner wall of the shell 100, the elastic arm 412 is not limited by the sliding part 310 in the radial direction of the fixing ring 411 any more, and therefore the limiting part 413 can be inserted into the gap formed between the limiting step surface 315 and the shell 100 more easily and can be separated from the gap more easily, and the structure is more reasonable.
