Description

Mouse device

The present invention relates to a mouse device.

The mouse device is an important external input device of the computer. It allows the user to move the mouse device to quickly move the mouse (cursor) on the computer screen, and allows the user to operate the mouse device. Perform quick input operations such as confirmation and cancellation on the computer. Therefore, the mouse device greatly improves the convenience for the user to operate the computer.

The buttons of the conventional mouse generally use a cantilever design. When the user presses the key, the elasticity of the key made of plastic can be used to deform the key to trigger the switch; after releasing the key, the elasticity of the key can be used to restore the key to the initial position. However, the disadvantage of this design is that due to the accumulation of manufacturing tolerances and assembly tolerances of the parts, the problem of empty stroke or overpressure occurs in mass production, which causes unstable button triggering power and hand feeling. At the same time, if the user wants to successfully trigger the switch, the applied force must be greater than the force that can trigger the switch plus the stress of the elastic deformation of the button, which limits the pursuit of a light-weight button tactile design.

Therefore, how to propose a mouse device that can solve the above-mentioned problems is one of the problems that the industry urgently wants to invest in research and development resources to solve.

In view of this, one objective of the present invention is to provide a mouse device that can solve the above-mentioned problems.

In order to achieve the above objective, according to one embodiment of the present invention, a mouse device includes a housing, a switch, a button, and a biasing element. The shell has an accommodating space therein. The switch is located in the accommodating space. The button covers the shell and includes a pivot part and a trigger part. The pivot part is pivotally connected with the housing. The trigger part extends to the accommodating space. The biasing element is located between the pivoting portion and the triggering portion, and applies a thrust to the button in the front and rear axial directions of the mouse device.

In one or more embodiments of the present invention, the mouse device further includes an abutting structure. The abutting structure is located on one side of the key outside the accommodating space. The biasing element contacts the abutting structure and the housing.

In one or more embodiments of the present invention, the button further includes an extension portion. The abutting structure is connected to the extension part. The biasing element abuts between the abutting structure and the housing.

In one or more embodiments of the present invention, the abutting structure is movably connected to the extension portion.

In one or more embodiments of the present invention, the extension part is a screw. The abutting structure is a nut. The biasing element abuts between the abutting structure and the housing.

In one or more embodiments of the present invention, the biasing element is a spring, which is sleeved outside the extension portion.

In one or more embodiments of the present invention, the housing includes a retaining wall. The extension part extends toward the retaining wall. The biasing element abuts between the abutting structure and the retaining wall.

In one or more embodiments of the present invention, the abutting structure is a part of the outer surface of the key.

In one or more embodiments of the present invention, the housing has a through hole. The button further includes a boss. The protruding column extends to the accommodating space through the through hole.

In one or more embodiments of the present invention, the housing further has two guiding walls. The two guide walls protrude to the accommodating space and are respectively connected to opposite sides of the through hole.

In one or more embodiments of the present invention, the outer surface of the housing partially sinks toward the accommodating space to form a recess. The housing also has a pivot hole located in the recessed portion. The pivoting part is pivotally connected to the pivoting hole in the recessed part.

To sum up, in the mouse device of the present invention, the button is pivotally connected to the housing by the pivotal portion, so the user does not need to overcome the elastic force generated by the conventional button with the cantilever design when pressing the button. Even with the accumulation of manufacturing tolerances and assembly tolerances of parts, the button of the present invention can maintain the state of contact with the switch by virtue of its own gravity. In this way, the key of the present invention not only does not have the problem of idle stroke and overpressure, but also meets the design requirements of light-weight tactile feeling. Furthermore, by providing a biasing element in the mouse device of the present invention to apply force to the housing and the button, the button can be kept in contact with the switch. In this way, even if the mouse device of the present invention is shaken or turned upside down, the button can still be kept in contact with the switch without shaking.

Please refer to Figure 1, Figure 2, and Figure 3. FIG. 1 is a three-dimensional assembly diagram of a mouse device 100 according to an embodiment of the present invention. FIG. 2 is a schematic partial cross-sectional view of the mouse device 100 in FIG. 1. FIG. FIG. 3 is a perspective exploded view showing some components of the mouse device 100 in FIG. 1. FIG. As shown in Figures 1 and 2, the mouse device 100 includes a housing 110, a circuit board 120, and buttons 130 和biasing element 140. The housing 110 includes a bottom shell 111, a top shell 112 and an outer cover 113. The bottom shell 111 and the top shell 112 are detachably assembled, and the accommodating space S is formed between the bottom shell 111 and the top shell 112. The outer cover 113 is detachably assembled on the side of the top shell 112 away from the bottom shell 111 and constitutes at least a part of the exterior surface of the mouse device 100. The circuit board 120 is located in the accommodating space S, and a switch 121 is provided thereon. The button 130 covers the top shell 112 and includes a pivot portion 131 and a trigger portion 132. The pivot portion 131 is pivotally connected to the pivot hole 112d1 (see FIG. 3) of the top shell 112. Specifically, the outer surface of the top shell 112 (that is, the surface of the top shell 112 opposite to the accommodating space S) is partially depressed toward the accommodating space S to form a recess 112d (see Figure 2), and pivotally connected The hole 112d1 is located in the recess 112d. In other words, the pivot portion 131 of the button 130 is pivotally connected to the pivot hole 112d1 in the recess 112d. In addition, the front section and the rear section of the outer surface of the top shell 112 are respectively covered by the buttons 130 and the outer cover 113. Therefore, it can be seen that the buttons 130 and the outer cover 113 together form the smooth upper appearance surface of the mouse device 100 and cover The lower recess 112d. The trigger portion 132 extends to the accommodating space S. The biasing element 140 is located outside the accommodating space S and between the pivoting portion 131 and the trigger portion 132, and applies a force to the button 130 in the front and rear axial direction A1 of the mouse device 100 to cause the trigger portion 132 to keep in contact with the switch 121. Specifically, as shown in Figure 2, the biasing element 140 applies a counterclockwise torque to the key 130 relative to the pivoting portion 131, so that the triggering portion 132 of the key 130 is positioned in the upper and lower axis of the mouse device 100. A2 provides stable downward force.

With the aforementioned structural configuration, the user does not need to overcome the elastic force generated by the conventional key using the cantilever design when pressing the key 130. Therefore, even if there is an accumulation of component manufacturing tolerances and assembly tolerances, the key 130 of this embodiment It is also possible to maintain the contact state with the switch 121 by its own gravity. With this, The button 130 of this embodiment not only does not have the problems of idle stroke and overpressure, but also meets the design requirements of light-weight tactile feel.

As shown in FIG. 1 and FIG. 2, the mouse device 100 further includes an abutting structure 150. The abutting structure 150 is connected to the button 130 and is located outside the accommodating space S. The biasing element 140 contacts the abutting structure 150 and the top shell 112 of the housing 110. Specifically, please refer to Figure 3 and Figure 4. FIG. 4 is another partial cross-sectional schematic diagram showing the mouse device 100 in FIG. 1. FIG. As shown in FIGS. 2 to 4, the button 130 further includes an extension portion 133 located outside the accommodating space S. The abutting structure 150 is connected to the extension part 133. Specifically, the extension portion 133 extends substantially rearward in the front-rear axis A1 of the mouse device 100. The extension part 133 is closer to the upper side than the pivot part 131 in the vertical axis A2 of the mouse device 100. In addition, the top shell 112 of the housing 110 includes a retaining wall 112 a located outside the accommodating space S. The retaining wall 112a is located in the recess 112d, and extends upward from the bottom of the recess 112d in the vertical axis A2 of the mouse device 100. As shown in Figure 2, the retaining wall 112a is substantially in the shape of a sheet. The extension 133 extends toward the retaining wall 112a. The biasing element 140 abuts between the abutting structure 150 and the retaining wall 112a.

In some embodiments, the retaining wall 112 a is located between the pivotal portion 131 and the extension portion 133 of the button 130. With this structural configuration, the distance between the retaining wall 112a and the extension 133 of the button 130 can be effectively shortened, so that the biasing element 140 can be reduced and the cost of parts can be saved.

In some embodiments, the extension 133 of the button 130 is a screw. The abutting structure 150 is a screw cap. The screw and the nut are screwed together. In other words, the extension 133 of the button 130 and the abutting structure 150 are screwed together. The biasing element 140 can abut between the nut and the retaining wall 112 a of the top shell 112. In some embodiments Among them, the biasing element 140 is a spring (for example, a compression spring), and is sleeved outside the extension 133 of the button 130. Thereby, the biasing element 140 can apply force to the top shell 112 of the housing 110 and the button 130 (via the abutment structure 150) to bring the two close together, and the extension 133 of the button 130 can also act on the biasing element. 140 for limit.

With the aforementioned structural configuration, the trigger portion 132 of the button 130 can be kept in contact with the switch 121. Therefore, even if the mouse device 100 of this embodiment is shaken or turned upside down, the button 130 can still be kept in contact with the switch 121 without shaking.

In addition, since the extension portion 133 of the button 130 and the abutment structure 150 are screwed together, it means that the abutment structure 150 is movably connected to the extension portion 133. Therefore, by rotating the abutting structure 150 relative to the extension 133, the user can adjust the distance between the abutting structure 150 and the retaining wall 112a of the top shell 112, thereby adjusting the biasing element 140 applied to the top of the shell 110. The strength of the shell 112 and the button 130 (via the abutment structure 150).

In practical applications, the mouse device 100 may further include a gasket (not shown). The washer can abut between the biasing element 140 and the abutment structure 150/retaining wall 112a. Thereby, the abrasion between the biasing element 140 and the abutment structure 150/retaining wall 112a can be effectively avoided.

On the other hand, as shown in FIGS. 2 to 4, the top shell 112 of the housing 110 has a through hole 112b. The button 130 further includes a protrusion 134. The protrusion 134 extends to the accommodating space S through the through hole 112b. As can be seen from Figures 2 and 3, since the key 130 is pressed with the pivoting portion 131 as the axis of rotation relative to the top shell 112, the through hole 112b of the top shell 112 is perpendicular to the axis of the pivoting portion 131 Has the largest width on a plane (for example, the plane presented in Figure 2), This allows the protrusion 134 passing through the through hole 112b to not collide with the inner wall of the through hole 112b when the key 130 swings.

As shown in FIGS. 2 and 4, the top shell 112 of the housing 110 also has two guide walls 112c. The guiding wall 112c protrudes to the accommodating space S, and is connected to opposite sides of the through hole 112b, respectively. With this configuration, the protrusion 134 of the limit button 130 can be effectively assisted, thereby preventing the button 130 from swinging without the pivoting portion 131 as a rotation axis. In order to achieve the aforementioned limiting function, the distance between the two guide walls 112c is smaller than the aforementioned maximum width of the through hole 112b.

In other embodiments, the button 130 can also cancel the configuration of the protrusion 134. The through hole 112b on the top shell 112 and communicating with the accommodating space S may be formed on the retaining wall 112a outside the accommodating space S, and allows the extension 133 of the button 130 to pass through. The two guide walls 112c on the top shell 112 and located in the accommodating space S can also be disposed on the retaining wall 112a outside the accommodating space S, and are respectively connected to opposite sides of the through hole 112b. In this way, the aforementioned purpose of preventing the button 130 from swinging without the pivoting portion 131 as the rotation axis can also be achieved.

Please refer to Figure 5. FIG. 5 is a schematic partial cross-sectional view of a mouse device 200 according to an embodiment of the present invention. One difference between this embodiment and the embodiment shown in FIG. 2 is that the abutting structure 235 of this embodiment is a part of the outer surface of the button 230. Specifically, the abutting structure 235 constitutes a wall surface of the recess 112d. The biasing element 140 abuts between the abutting structure 235 and the retaining wall 112 a of the top shell 112. The biasing element 140 is a compression spring, sleeved outside the extension 233 of the button 130, and one end of the biasing element 140 abuts against the retaining wall 112a of the top shell 112. Another difference between this embodiment and the embodiment shown in FIG. 2 is that the extension 233 of this embodiment does not have an external thread. By pressing the button 230 When a force is applied to the front and rear axis A1 of the mouse device 100, the biasing element 140 can apply a counterclockwise torque to the button 230 relative to the pivot portion 131, so that the trigger portion 132 of the button 230 is on the mouse The vertical axis A2 of the device 100 provides a stable downward force.

It should be noted that the biasing element 140 is not limited to be provided in the mouse device 100 in the above-mentioned manner. In practical applications, the biasing element can be a component that includes two magnetic components that can attract each other, and the two magnetic components are respectively disposed on the top shell 112 and the button 130, which can also achieve the application of the top shell 112 and the button 130. For the purpose of bringing the two closer together.

From the above detailed description of the specific embodiments of the present invention, it can be clearly seen that in the mouse device of the present invention, the button is pivotally connected to the housing by a pivot part, so the user does not need to overcome the use of The elastic force generated by the conventional button of the cantilever design. Even with the accumulation of manufacturing tolerances and assembly tolerances of parts, the button of the present invention can maintain the state of contact with the switch by virtue of its own gravity. In this way, the key of the present invention not only does not have the problem of idle stroke and overpressure, but also meets the design requirements of light-weight tactile feeling. Furthermore, by providing a biasing element in the mouse device of the present invention to apply force to the housing and the button, the button can be kept in contact with the switch. In this way, even if the mouse device of the present invention is shaken or turned upside down, the button can still be kept in contact with the switch without shaking.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention. Anyone who is familiar with the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection of the present invention The scope shall be subject to the scope of the attached patent application.
