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 its original 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.

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 exerts a downward force on the button in the upper and lower 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 connected to the button and extends to 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 extending to the accommodating space. 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 portion has a screw hole. The abutting structure includes a threaded portion and a head connected to each other. The threaded part and the screw hole are screwed together. The biasing element abuts between the head 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 mouse device further includes a gasket. The gasket abuts between the housing and the biasing element.

In one or more embodiments of the present invention, the housing has a through hole. The abutting structure 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 guide wall protrudes to the accommodating space, and is connected to opposite sides of the through hole respectively.

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.

As shown in FIGS. 1 and 2, the mouse device 100 includes a housing 110, a circuit board 120, buttons 130, and a 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. according to The key 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 112c1 (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 112c (see FIG. 2), and pivotally connected The hole 112c1 is located in the recess 112c. In other words, the pivot portion 131 of the button 130 is pivotally connected to the pivot hole 112c1 in the recess 112c. 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 112c. The trigger portion 132 extends to the accommodating space S. The biasing element 140 is located between the pivoting portion 131 and the trigger portion 132, and applies a downward force to the button 130 in the vertical axis A2 of the mouse device 100, so that the trigger portion 132 remains in contact with the switch 121.

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. In this way, the button 130 of this embodiment not only does not have the problem 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 extends to 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 extending to the accommodating space S. Extension 133 in The front and rear axis A1 of the mouse device 100 is located between the pivoting portion 131 and the triggering portion 132. The trigger portion 132 and the extension portion 133 extend substantially downward in the vertical axis A2 of the mouse device 100. The abutting structure 150 is connected to the extension part 133. The biasing element 140 abuts between the abutment structure 150 and the top shell 112 of the housing 110.

Specifically, the extension 133 of the button 130 has a screw hole 133a. The abutting structure 150 includes a threaded portion 151 and a head 152 connected to each other. The threaded portion 151 and the screw hole 133a are screwed to each other. In other words, the extension 133 of the button 130 and the abutting structure 150 are screwed together. The width of the head 152 is greater than the width of the threaded portion 151, so the biasing element 140 can abut between the head 152 and the top shell 112 of the housing 110. In some embodiments, 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. In other words, the biasing element 140 abuts the top shell 112, and provides a stable downward force to the button 130 in the vertical axis A2 of the mouse device 100 via the abutment structure 150.

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 controlling the depth of the threaded portion 151 of the abutting structure 150 into the screw hole 133a of the extension portion 133, the user can adjust the head 152 and the top of the abutting structure 150. The distance between the shells 112 is adjusted so as to adjust the force exerted by the biasing element 140 on the top shell 112 of the shell 110 and the button 130 (via the abutment structure 150).

In practical applications, the abutting structure 150 and the button 130 can also be two connected parts of a single structure, and can be made of plastic through an injection molding process, but the present invention is not limited to this.

In some embodiments, as shown in FIGS. 2 to 4, the mouse device 100 further includes a gasket 160. The gasket 160 abuts between the top shell 112 and the biasing element 140. In this way, the abrasion between the top shell 112 and the biasing element 140 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 112a. The abutting structure 150 extends to the accommodating space S through the through hole 112a. 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 112a of the top shell 112 is perpendicular to the axis of the pivoting portion 131 A horizontal plane (for example, the plane shown in FIG. 2) has a maximum width to allow the extension 133 passing through the through hole 112a to not collide with the inner wall of the through hole 112a when the button 130 swings.

As shown in FIGS. 3 and 4, the top shell 112 of the housing 110 also has two guide walls 112b. The guiding wall 112b protrudes to the accommodating space S, and is connected to opposite sides of the through hole 112a, respectively. With this configuration, the extension portion 133 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 112b is smaller than the aforementioned maximum width of the through hole 112a. In addition, as shown in FIG. 4, the washer 160 abuts between the biasing element 140 and the two guide walls 112b.

It should be noted that the biasing element 140 is not limited to the above The type is set in the mouse device 100. In practical applications, the biasing element may include two mutually attracting magnetic components, which are respectively arranged on the top shell 112 and the button 130, and can also be applied to the top shell 112 and the button 130 to bring the two close together. The purpose of the power.

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.
