Description

Technical Field

[0001] This invention relates to a mouse device. Background Technology

[0002] As an important external input device for computers, the mouse allows users to quickly move the cursor on the computer screen and perform quick input operations such as confirming and canceling. Therefore, the mouse greatly improves the convenience of computer operation.

[0003] Currently, a mouse device with a lateral scroll wheel has ribs extending from both sides of the scroll wheel base. When a finger touches the scroll wheel and the scroll wheel base is swung, the left and right ribs press left and right button switches, thus producing the function of the scroll bar moving left and right in the software. However, this design is not conducive to the flexibility of the internal component layout and the efficiency of space utilization of the mouse device.

[0004] Therefore, how to develop a mouse device that can solve the above problems is one of the issues that the industry is currently eager to address by investing research and development resources in. Summary of the Invention

[0005] In view of this, the object of the present invention is to provide a mouse device that can solve the above-mentioned problems.

[0006] To achieve the above objectives, according to one embodiment of the present invention, a mouse device includes a housing, a button switch, a swing arm, a scroll wheel holder, and a scroll wheel. The housing includes a base plate. The button switch is located above the base plate and includes a button. The swing arm includes a pivot portion, a first extension portion, and a second extension portion. The pivot portion is pivotally connected to the base plate. The first extension portion connects to the pivot portion and abuts against the button. The second extension portion connects to the pivot portion. The scroll wheel holder is located above the base plate and is configured to swing laterally toward the second extension portion to move the second extension portion, thereby rotating the swing arm to press the button with the first extension portion. The swing arm is located on the side of the scroll wheel holder. The scroll wheel is rotatably disposed within the scroll wheel holder.

[0007] In one or more embodiments of the present invention, the second extension abuts against the roller seat.

[0008] In one or more embodiments of the present invention, the first extension has a contact point that contacts the button. The second extension has a trigger point and is configured to be subjected to force by the roller seat.

[0009] In one or more embodiments of the present invention, the distance from the contact point to the rotation axis of the swing arm is greater than the distance from the trigger point to the rotation axis.

[0010] In one or more embodiments of the present invention, the roller base includes a first magnet. The second extension includes a second magnet. The like poles of the first magnet and the second magnet are opposite each other.

[0011] In one or more embodiments of the present invention, the mouse device further includes a reset member. The reset member is disposed on the side of the second extension away from the scroll wheel seat and configured to reset the second extension toward the scroll wheel seat.

[0012] In one or more embodiments of the present invention, the housing further includes a baffle wall. The baffle wall is disposed on the base plate. A second extension is located between the roller seat and the baffle wall. A reset member is disposed between the second extension and the baffle wall.

[0013] In one or more embodiments of the present invention, the push-button switch and the roller seat are located on the same side of the swing arm.

[0014] In one or more embodiments of the present invention, the housing further includes a support structure. The support structure is disposed on a base plate and includes two limiting walls. The roller seat includes an extension post. The extension post is positioned between the two limiting walls.

[0015] In one or more embodiments of the present invention, the extension post includes a insert. A communicating receiving groove and a slot are formed between the two limiting walls. The receiving groove receives a portion of the extension post. The slot is located between the receiving groove and the base plate and is configured for insertion of the insert.

[0016] In one or more embodiments of the present invention, when the insert is outside the slot, the extension post is rotatably limited between the two limiting walls. When the insert is inserted into the slot, the insert engages between the two inner walls of the slot.

[0017] In one or more embodiments of the present invention, the junction between the receiving groove and the slot has a chamfered structure.

[0018] In summary, in the mouse device of the present invention, the scroll wheel base can be laterally swung to rotate the swing arm, thereby pressing the button switch via the rotating swing arm. This allows the position of the button switch relative to the scroll wheel base to be arbitrarily changed by adjusting the shape of the swing arm, effectively increasing the flexibility of the internal component layout and space utilization efficiency of the mouse device. By making the distance from the contact point between the swing arm and the button to the rotation axis of the swing arm greater than the distance from the trigger point between the scroll wheel base and the swing arm to the rotation axis, the distance the scroll wheel base needs to swing and the force applied to trigger the button switch are increased, thereby reducing the chance of accidentally pressing the button switch when the scroll wheel is pressed vertically. By designing a slot in the support structure on the base plate for the insertion of the extension post of the scroll wheel base, the scroll wheel base can be effectively prevented from swaying when the scroll wheel is pressed vertically, thus avoiding accidental button switch activation.

[0064] The following describes several embodiments of the present invention with reference to the drawings. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details are not intended to limit the invention. That is, in some embodiments of the invention, these practical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and elements will be shown in the drawings in a simple schematic manner.

[0065] Please refer to Figure 1 as well as Figure 2 . Figure 1 A perspective view of a mouse device 100 according to an embodiment of the present invention is shown. Figure 2 To show Figure 1 A partial perspective view of some components of the mouse device 100. (See attached image.) Figure 1 and Figure 2 As shown, in this embodiment, the mouse device 100 includes a housing 110, a circuit board 120, and two swing arms 130. Figure 2 Only one is shown in the diagram), roller seat 150, and roller 160. Housing 110 includes a base plate 111. Circuit board 120, swing arm 130, and roller seat 150 are disposed within housing 110 and located above base plate 111. Circuit board 120 has two push-button switches 121 (…). Figure 2 (Only one is shown in the image). Two push-button switches 121 are located on opposite sides of the roller base 150. Each push-button switch 121 includes a button 121a. Two swing arms 130 are located on opposite sides of the roller base 150. Each swing arm 130 includes a pivot portion 131, a first extension portion 132, and a second extension portion 133. The pivot portion 131 is pivotally connected to the base plate 111 via a rotation axis A2, allowing the swing arm 130 to rotate around the rotation axis A2. The first extension portion 132 connects to the pivot portion 131 and abuts against the button 121a of the corresponding push-button switch 121. The second extension portion 133 connects to the pivot portion 131. Specifically, the first extension portion 132 and the second extension portion 133 extend in opposite directions from opposite sides of the pivot portion 131. The first extension 132 extends rearward relative to the pivot 131 toward the mouse device 100, while the second extension 133 extends forward relative to the pivot 131 toward the mouse device 100. The scroll wheel seat 150 is configured to laterally swing toward the second extension 133 to move the second extension 133, thereby rotating the swing arm 130 to press the button 121a of the key switch 121 with the first extension 132. The two swing arms 130 are located on opposite sides of the scroll wheel seat 150. The scroll wheel seat 150 includes a receiving frame 151. The scroll wheel 160 is rotatably received within the inner edge of the receiving frame 151.

[0066] With the aforementioned structural configuration, the position of the button switch 121 relative to the scroll wheel base 150 can be arbitrarily changed by adjusting the shape of the swing arm 130, thereby effectively increasing the flexibility of the internal component layout and the efficiency of space utilization of the mouse device 100.

[0067] For example, such as Figure 2 As shown, the push-button switch 121 and the roller seat 150 are located on the same side of the corresponding swing arm 130. With this configuration, the push-button switch 121 can be positioned on the rear side of the roller seat 150, and the swing arm 130 can extend from the front to the rear side of the roller seat 150, thereby freeing up space on both sides of the roller seat 150 for the layout of other components. In practical applications, depending on the position of the push-button switch 121 relative to the roller seat 150, the shape of the swing arm 130 can also be adjusted to an L-shape or a U-shape, but this invention is not limited to these limitations.

[0068] like Figure 2 As shown, in this embodiment, the mouse device 100 further includes a fixing member 140. The fixing member 140 fixes the swing arm 130 to the base plate 111. Specifically, the swing arm 130 is rotatably sleeved on the outer edge of the fixing member 140 to rotate about the aforementioned rotation axis A2. In some embodiments, the fixing member 140 is a screw fastened to the base plate 111, but the present invention is not limited thereto. In other embodiments, the fixing member 140 and the base plate 111 are a single-piece structure made of plastic by injection molding, but the present invention is not limited thereto.

[0069] Furthermore, such as Figure 2 As shown, in this embodiment, the housing 110 further includes support structures 113a and 113b. Support structures 113a and 113b are disposed on the base plate 111. The roller seat 150 further includes extension columns 152a and 152b. Extension columns 152a and 152b are connected to opposite sides of the receiving frame 151 and extend in the opposite direction. With the extension columns 152a and 152b rotatably supported on the support structures 113a and 113b respectively, the roller seat 150 can rotate about the rotation axis A1 passing through the extension columns 152a and 152b. Thus, the receiving frame 151 of the roller seat 150 can swing left and right based on the rotation axis A1 to achieve lateral swinging towards and away from the second extension 133.

[0070] In some embodiments, the extension columns 152a, 152b and the base plate 111 are integrally formed from plastic by injection molding, but the present invention is not limited thereto.

[0071] Please refer to Figure 3A as well as Figure 3B . Figure 3A To show Figure 2The structure in the image is viewed in cross-section along line segment 3A-3A. Specifically, Figure 3A The diagram shows a cross-sectional view of roller 160 when it is not under pressure and is not wobbling. Figure 3B To show Figure 2 Another cross-sectional view of the structure viewed along line segment 3A-3A. Specifically, Figure 3B A cross-sectional view is shown with roller 160 swinging to one side (left side). (See diagram below.) Figures 2 to 3B As shown, in this embodiment, since the second extension 133 of the swing arm 130 directly abuts against the roller seat 150, the receiving frame 151, which swings laterally toward the second extension 133, pushes the second extension 133, thereby causing the swing arm 130 to rotate around the rotation axis A2 and press the button 121a of the push-button switch 121 with the first extension 132. In practical applications, the user can push the roller 160 laterally with their finger to make the roller seat 150 swing to the left and right, thereby triggering the push-button switches 121 located on both sides of the roller seat 150 respectively. When the user's finger leaves the roller 160, the button 121a of the push-button switch 121 will rebound, causing the swing arm 130 to rotate in the opposite direction, thereby causing the roller seat 150 to be pushed back by the swing arm 130 and reset to its initial position before being pushed laterally (e.g., the swing arm 130 is at the initial position before being pushed laterally). Figure 2 (Position in the middle). For example, in this embodiment, when the roller seat 150 is pushed to the left, the left swing arm 130 can trigger the button switch 121 located on the left side of the roller seat 150; when the roller seat 150 is pushed to the right, the right swing arm 130 can trigger the button switch 121 located on the right side of the roller seat 150.

[0072] Please refer to Figure 3C It is shown Figure 2 Another cross-sectional view of the structure viewed along line segment 3A-3A. Specifically, Figure 3C The diagram shows a cross-sectional view after roller 160 is pressed down. Figure 2 , Figure 3A and Figure 3CAs shown, in this embodiment, a push-button switch 122 is also provided on the circuit board 120. The push-button switch 122 is located below the roller seat 150 and includes a button 122a. Specifically, when the roller 160 is not pressed, the extension post 152a of the roller seat 150 is located above and separated from the button 122a of the push-button switch 122 by a gap; when the roller 160 is pressed, the extension post 152a of the roller seat 150 can press down the button 122a to trigger the push-button switch 122. The support structure 113a includes two limiting walls 113a1 and 113a2. The extension post 152a is limited between the two limiting walls 113a1 and 113a2, so as to be guided by the two limiting walls 113a1 and 113a2 when moving toward and away from the push-button switch 122. In practical applications, the user can press the scroll wheel 160 with their finger to cause the extension post 152a of the scroll wheel seat 150 to press down toward the push-button switch 122. When the user's finger leaves the scroll wheel 160, the button 122a of the push-button switch 122 will spring back and push the extension post 152a upward, thereby returning the scroll wheel seat 150 to its initial position before it was pressed down (such as the swing arm 130 at...). Figure 3A (Position in the middle). It can be seen that the extension column 152a can not only rotate relative to the supporting structure 113a based on the rotation axis A1, but also move linearly toward and away from the base plate 111.

[0073] In addition, such as Figure 2 As shown, the support structure 113b supports and limits the extension column 152b, so that the extension column 152b can rotate relative to the support structure 113b based on the rotation axis A1.

[0074] like Figures 3A to 3C As shown, in this embodiment, the extension post 152a includes a connected post body 152a1 and a insert 152a2. The post body 152a1 extends substantially along the axis of rotation A1 away from the receiving frame 151. The insert 152a2 extends downward from the bottom of the post body 152a1. A communicating receiving groove C1 and a slot C2 are formed between the aforementioned two limiting walls 113a1 and 113a2. The receiving groove C1 receives a portion of the post body 152a1 of the extension post 152a. The slot C2 is located between the receiving groove C1 and the base plate 111 and is configured for insertion of the insert 152a2. Specifically, the width of the receiving groove C1 is larger than the width of the slot C2. When the insert 152a2 is outside the slot C2, the extension post 152a is rotatably limited between the aforementioned two limiting walls 113a1 and 113a2, as shown. Figure 3A and Figure 3B As shown. When the insert 152a2 is inserted into the slot C2, the insert 152a2 engages between the two inner walls of the slot C2, as shown. Figure 3CAs shown. Therefore, when a user presses the scroll wheel 160 with their finger, causing the extension post 152a of the scroll wheel base 150 to depress and trigger the push-button switch 122, the support structure 113a can prevent the scroll wheel base 150 from swinging based on the rotation axis A1 by engaging the slot C2 of the insert 152a2, thereby preventing accidental activation of the push-button switch 121. Furthermore, this structural configuration ensures that the scroll wheel 160 makes stable contact with the button 122a of the push-button switch 122 when pressed down.

[0075] Please refer to Figure 3D It is shown Figure 2 The structure within is shown in a partial stereoscopic view from another perspective. Specifically, Figure 3D This diagram shows roller 160 without pressure and without wobbling. Figure 3D As shown, in this embodiment, the extension post 152a further includes a protrusion 152a3 extending downward from the bottom of the post 152a1. The protrusion 152a3 is configured to abut against the button 122a of the push-button switch 122. Thus, when the roller 160 is not pressed, the protrusion 152a3 is located above and spaced apart from the button 122a of the push-button switch 122; when the roller 160 is pressed, the protrusion 152a3 presses down on the button 122a, triggering the push-button switch 122. This structural configuration ensures precise pressing contact between the protrusion 152a3 and the button 122a, but the invention is not limited thereto.

[0076] like Figures 3A to 3C As shown, in this embodiment, a chamfered structure C3 is provided at the junction between the receiving groove C1 and the slot C2. The width of the chamfered structure C3 gradually decreases from the receiving groove C1 toward the slot C2. The chamfered structure C3 can increase the smoothness of the insert 152a2 during insertion into the slot C2. In some embodiments, the chamfered structure C3 is an inclined surface relative to the inner walls of the receiving groove C1 and the slot C2, but the present invention is not limited thereto.

[0077] like Figure 1 and Figure 2 As shown, the mouse device 100 further includes a left button 181 and a right button 182. The left button 181 and the right button 182 are movably connected to the housing 110 and configured to move toward and away from the base plate 111. The circuit board 120 is further provided with push-button switches 123a and 123b. The push-button switches 123a and 123b are located on opposite sides of the scroll wheel base 150 and are respectively configured to be triggered by the pressed left button 181 and right button 182.

[0078] Please refer to Figure 4 It is shown Figure 2 A top view of some of the components. (e.g.) Figure 4As shown, in this embodiment, the first extension 132 of the swing arm 130 has a contact point P1 that contacts the button 121a of the push-button switch 121. The second extension 133 of the swing arm 130 has a trigger point P2 configured to be subjected to force by the roller seat 150. In this embodiment, the trigger point P2 is a protrusion protruding from the surface of the second extension 133 facing the roller seat 150 and contacting the roller seat 150. The distance D1 from the contact point P1 to the rotation axis A2 of the swing arm 130 is greater than the distance D2 from the trigger point P2 to the rotation axis A2. This increases the distance the roller seat 150 needs to swing and the force applied when the push-button switch 121 is to be triggered, thereby reducing the chance of accidentally triggering the push-button switch 121 when the roller 160 is pressed vertically. However, the present invention is not limited to this embodiment. In some embodiments, the second extension 133 of the swing arm 130 contacts the roller seat 150 in a surface contact manner, and therefore there is no specific trigger point P2. In some embodiments, the trigger point P2 may also be disposed on the surface of the roller seat 150 facing the second extension 133 and abut against the surface of the second extension 133.

[0079] In some implementations, such as Figure 2 As shown, the housing 110 further includes a retaining wall 112. The retaining wall 112 is disposed on the base plate 111. The mouse device 100 further includes a reset member 170. The reset member 170 is disposed between the second extension 133 on the side away from the scroll wheel seat 150 and the retaining wall 112, and is configured to allow the second extension 133 to reset towards the scroll wheel seat 150. Thus, in addition to the button 121a of the push-button switch 121 being able to spring back and reset the swing arm 130, this embodiment can also ensure that the swing arm 130 can reset by means of the reset member 170.

[0080] In some embodiments, the retaining wall 112 and the base plate 111 are single-piece structures made of plastic by injection molding, but the present invention is not limited thereto. In some embodiments, the retaining wall 112 and the base plate 111 are two-piece structures (i.e., not integrally molded), and the retaining wall 112 is fixed to the base plate 111, for example, by insertion.

[0081] In some embodiments, the reset member 170 is a compression spring, but the present invention is not limited thereto.

[0082] Please refer to Figure 5 as well as Figure 6 . Figure 5 A partial perspective view showing some components of a mouse device 100 according to another embodiment of the present invention. Figure 6 To show Figure 5 A 3D view of the swing arm 230. (See diagram below.) Figure 5 and Figure 6As shown, in this embodiment, the base plate 111, circuit board 120, fixing member 140, roller 160, and reset member 170 are the same as those in the previous embodiment. Figure 2 The embodiments shown are described above, and therefore, the relevant descriptions of these components can be found in the preceding text and will not be repeated here. Compared to Figure 2 The embodiment shown is a modification of the swing arm 230 and the roller seat 250.

[0083] In detail, in this embodiment, the roller seat 250 includes a receiving frame 251 and extension posts 152a and 152b. Compared to Figure 2 In the embodiment shown, the receiving frame 251 of this embodiment has a first magnet 251a on its side. Additionally, each swing arm 230 includes a pivot portion 131, a first extension portion 132, and a second extension portion 233. Compared to Figure 2 In the illustrated embodiment, the second extension 233 includes a second magnet 233a located on the side of the second extension 233 facing the roller seat 250. The like poles of the first magnet 251a and the second magnet 233a are opposite each other. That is, the first magnet 251a and the second magnet 233a, when brought close together, increase the magnetic repulsion force. Therefore, the roller seat 250, which swings laterally toward the second extension 233, can use the magnetic repulsion force to move the second extension 233 in a non-contact manner, thereby causing the swing arm 230 to rotate and achieving the purpose of triggering the push-button switch 121 with the first extension 132.

[0084] From the detailed description of the specific embodiments of the present invention above, it is clear that the position of the scroll wheel base can be arbitrarily changed by adjusting the shape of the swing arm, thereby effectively increasing the flexibility of the internal component layout and space utilization efficiency of the mouse device. By making the distance from the contact point between the swing arm and the button to the rotation axis of the swing arm greater than the distance from the trigger point between the scroll wheel base and the swing arm to the rotation axis, the distance the scroll wheel base needs to swing and the force applied when the button switch is to be triggered can be increased, thereby reducing the situation of accidentally triggering the button switch when the scroll wheel is pressed vertically. By designing a slot on the support structure of the base plate for the insertion of the extension post of the scroll wheel base, the scroll wheel base can be effectively prevented from swinging when the scroll wheel is pressed vertically, thereby avoiding accidental triggering of the button switch.

[0085] Although the present invention has been described above with reference to embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the appended claims.
