[0035] It can be understood that the main body 10 of the embodiment further comprises a control mainboard 13 arranged in the main shell 11, the trigger switch 12 is electrically connected with the control mainboard 13, so as to apply an electric signal to the control mainboard 13 when the force receiving plate 211 is pressed, so as to realize the control of the cursor; and further comprises a scroll wheel 50, a side key 40 and other structures, so as to realize the basic control mode of the mouse 100.

[0037] In the embodiment, the sensitivity of the force receiving plate 211 to trigger the trigger switch 12 is improved by the provision of the elastic member 23. The material of the key 21 can be one of magnesium alloy, aluminum alloy, magnesium-aluminum alloy, nickel alloy, zinc alloy, ABS (Acrylonitrile Butadiene Styrene), or carbon fiber when being provided, so that the key 21 has good structural strength.

[0038] The force receiving plate 211 and the force arm 212 can be integrally provided or separately provided, and when they are separately formed, they can be connected subsequently, such as welding between metal materials or ultrasonic welding between plastic materials, to realize the connection of the two, so that the rotation of the force receiving plate 211 is realized by the rotation of the force arm 212 relative to the main shell 11 through the rotating shaft 22.

[0039] Specifically, the force receiving plate 211 and the force arm 212 of the embodiment are integrally formed, so that the rapid forming of the key 21 is facilitated, and the structural strength between the two can be guaranteed. Further, the material of the key 21 of the embodiment is preferably magnesium-aluminum alloy. Since the density of magnesium-aluminum alloy is generally less than 1.8 g·cm-3, it has the characteristics of low density, so that the prepared key 21 can have the characteristics of light weight, facilitating the movement of the mouse 100 during use by the user. At the same time, magnesium-aluminum alloy has the advantages of good structural strength, good rigidity and stable properties, so when it is used to prepare the key 21 of the embodiment, the key 21 itself can not deform to transmit the pressing force signal when the pressing force is applied to the trigger switch 12, has higher sensitivity of signal transmission, and at the same time avoids deformation of the key 21, guarantees the number of clicks, and has a longer service life.

In other embodiments, the force arm 212 can be provided with a limiting column, and the second mounting portion 152 can be provided with a limiting groove, and the movement of the force arm 212 in the left-right direction can also be limited.

[0048] Further, please refer to Figure 2 , Figure 5 and Figure 8The third limiting structure 2112 is arranged on the stress plate 211, the fourth limiting structure 17 is arranged on the first mounting portion 151 of the mounting frame 15, the third limiting structure 2112 and the fourth limiting structure 17 are matched, the button 21 can be in a stable installation state when the button 21 is in a static state, and the stress plate 211 is prevented from excessively moving upwards relative to the first mounting portion 151 and from being separated from the mounting frame 15 when the button 21 returns to the original position after the pressing force disappears; further, the third limiting structure 2112 and the fourth limiting structure 17 are matched, and the elastic member 23 can be in a compressed state when the stress plate 211 is in a static state.

[0049] Specifically, the third limiting structure 2112 of the embodiment is in the shape of a hook, the fourth limiting structure 17 is a through groove arranged on the first mounting portion 151, and the third limiting structure 2112 is arranged in the through groove and hooked on the groove wall of the through groove.

[0050] Please refer to Figure 6 In an embodiment of the utility model, in order to reduce the weight of the force arm 212, the force arm 212 is provided with a weight-reducing hole 2121, the weight of the force arm 212 can be reduced through the arrangement of the weight-reducing hole 2121, and the rotation of the button 21 and the force arm 212 is prevented from being affected when the button 21 receives a pressing force.

[0051] Further, when the weight-reducing hole 2121 is arranged, the force arm 212 is provided with a reinforcing rib 2122 to ensure the rigidity of the force arm 212, the reinforcing rib 2122 extends in the length direction of the force arm 212 and also extends in the height direction, thus the rigidity of the force arm 212 is increased through the arrangement of the reinforcing rib 2122, the force arm 212 does not need to be deformed through the arrangement of the elastic member 23 in the application, the rigidity of the force arm 212 is increased through the arrangement of the reinforcing rib 2122, and the force arm 212 is prevented from being deformed.

[0052] Please refer to Figure 2 , Figure 4 , Figure 5 and Figure 7 In an embodiment of the utility model, in order to increase the feedback speed of triggering the trigger switch 12, the trigger switch 12 and the bottom plate 14 of the main shell are arranged at an included angle, the included angle is an acute angle, as shown in Figure 7 The trigger arm 2111 is arranged on the stress plate 211, and the trigger arm 2111 and the trigger switch 12 are arranged opposite to each other, compared with the mode that the trigger switch 12 is arranged on the control main plate 13 in the horizontal direction, the trigger arm 2111 arranged in this way can be close to the “0 threshold value” with the trigger key 121 on the trigger switch 12, and the pressure can be directly transmitted to the trigger key 121 in a straight line when the stress plate 211 is pressed, as shown inFigure 7 As shown by the arrow a, when the pressing force is transmitted to the trigger key 121, the pressing force is transmitted along an arc route. The inclined arrangement of the trigger switch 12 improves the feedback rate of the pressing force, and the reaction speed is faster, and the efficiency is high.

[0053] It can be understood that the trigger key 121 is provided with a reset spring. When the key 21 presses the trigger key 121, the reset spring is elastically deformed. When the pressing force disappears, the reset spring quickly pushes the key 21 back to the original position.

[0054] Further, referring to Figure 7 , the trigger arm 2111 has a trigger surface 2113, and the trigger key 121 of the trigger switch 12 has a matching surface 1211. The trigger surface 2113 and the matching surface 1211 are arranged in parallel to enable the trigger surface 2113 and the matching surface 1211 to quickly resist each other, realize force transmission, and thus ensure the feedback rate of the pressing force.

Part of the elastic member 23 is accommodated in the guide column 2123 to limit the installation of the elastic member 23. The second mounting portion 152 is provided with a guide member 155, and the elastic member 23 is sleeved on the guide member 155 to limit the extension and contraction of the elastic member 23 and ensure the stability of the extension and contraction of the elastic member 23 along the axis thereof.

[0056] The above mouse 100 is provided with the elastic member 23 at the end of the force arm 212. When the force receiving plate 211 is in a static state, the front end of the force receiving plate 211 can be in a "0 threshold" state with the trigger switch 12, i.e., the force receiving plate 211 can be in a state close to or in contact with the trigger switch 12. When the force receiving plate 211 is pressed downward, the elastic member 23 applies an upward elastic force to the force arm 212, and the force receiving plate 211 tends to move downward. The force receiving plate 211 and the trigger switch 12 can be quickly triggered, and a small force applied by the hand can drive the trigger switch 12, improving the efficiency of the trigger switch 12 and thus improving the reaction rate of the entire mouse 100 and the use feeling. The material of the key 21 is magnesium-aluminum alloy. The magnesium-aluminum alloy is light in weight and has sufficient rigidity, avoiding deformation under the pressing force and ensuring the service life. Two keys 21 are arranged side by side. Each key 21 can independently receive the pressing force, ensuring the sensitivity of the pressing feedback. The first limiting structure 24 and the second limiting structure 16 are matched to avoid the key 21 from swinging left and right under the pressing force, thus ensuring the accuracy of the force feedback.
