Detailed Description
Fig. 1 is a top view of a mouse according to an embodiment of the present invention. Fig. 2 is a perspective view of a part of the components of the mouse of fig. 1. Referring to fig. 1 and 2, a mouse 100 of the present embodiment includes a mouse body 110 and a scroll wheel module 120. The wheel module 120 includes a first wheel 122 and a second wheel 124, and the first wheel 122 and the second wheel 124 are respectively rotatably disposed on the mouse body 110, so that the wheel module 120 is in the form of a dual wheel.
With this configuration, the mouse 100 of the present embodiment can provide more diversified operation functions through the wheel module 120, compared to a mouse with only a single wheel. For example, the first wheel 122 and the second wheel 124 can be used to perform at least two functions of drawing a window, zooming a window, and adjusting a volume. Therefore, the user can alternately operate the first wheel 122 and the second wheel 124 with a single finger to perform various functions without adding additional function keys to provide the required functions, so that the operation of the mouse 100 is simple and intuitive.
In the present embodiment, the first roller 122 may be made of plastic, and the second roller 124 may be made of metal, so that the two rollers can be easily distinguished by users through different materials. In addition, the first roller 122 and the second roller 124 may have different colors or have different outer diameters to generate a height difference, which is helpful for a user to distinguish the two rollers.
FIG. 3 is a cross-sectional view of the mouse of FIG. 2 taken along line I-I. Referring to fig. 3, specifically, the first roller 122 has a first shaft portion 1221 and a first wheel portion 1222 connected to each other, and the second roller 124 has a second shaft portion 1241 and a second wheel portion 1242 connected to each other. The first wheel 122 and the second wheel 124 are rotatably disposed on the mouse body 110 along the same rotation axis a1 by the first shaft portion 1221 and the second shaft portion 1241, respectively. A user may apply force to the first wheel portion 1222 to rotate the first roller 122 or to the second wheel portion 1242 to rotate the second roller 124. The roller module 120 further includes a shaft connecting assembly 126, the shaft connecting assembly 126 is, for example, a bearing and is connected between the first shaft portion 1221 and the second shaft portion 1241, and the first shaft portion 1221 and the second shaft portion 1241 are adapted to rotate relative to each other via the shaft connecting assembly 126. Specifically, the first shaft portion 1221 is formed on an inner wall of the first wheel portion 1222 and extends therefrom through the shaft connection assembly 126 along the rotational axis a 1. The second shaft portion 1241 is formed in an inner wall of the second wheel portion 1242 and extends therefrom along the rotational axis a 1. In addition, the second shaft portion 1241 includes a stop structure 1241a and a hollow portion 1241c, the stop structure 1241a is connected between the inner wall of the second wheel portion 1242 and the hollow portion 1241c, the thickness of the stop structure 1241a and the thickness of the hollow portion 1241c are different to form a stepped groove structure, the stop structure 1241a stops the shaft connecting assembly 126 at its position, and the hollow portion 1241c is sleeved on the shaft connecting assembly 126. That is, in the radial direction of the rotation axis a1, the first shaft portion 1221, the shaft connection assembly 126, and the second shaft portion 1241 are arranged in this order from the inside to the outside.
As described above, the shaft connecting assembly 126 is disposed between the first roller 122 and the second roller 124 which are coaxially disposed, so that the first roller 122 and the second roller 124 can smoothly rotate relatively. Therefore, either one of the first roller 122 and the second roller 124 can be independently operated without undesirably moving the other, thereby having good controllability.
In the present embodiment, the shaft connecting element 126 is, for example, a ball bearing, and includes an inner layer structure 1261 connected to the first shaft portion 1221, an outer layer structure 1262 connected to the second shaft portion 1241, and a ball layer structure 1263 disposed between the inner layer structure 1261 and the outer layer structure 1262. The inner layer 1261 and the outer layer 1262 can slide relative to each other about the rotation axis a1 by rolling of the balls 1263a in the ball layer 1263, so that the first shaft portion 1221 and the second shaft portion 1241 rotate relative to each other along the rotation axis a 1. Specifically, when the first roller 122 rotates, the first shaft portion 1221 rotates together with the inner layer structure 1261 connected thereto. At this time, the inner layer structure 1261 can be smoothly rotated without moving the outer layer structure 1262 by the rolling of the balls 1263a of the ball layer structure 1263, and the outer layer structure 1262 and the second shaft portion 1241 connected thereto are not rotated. Conversely, when the second roller 124 rotates, the second shaft portion 1241 rotates with the outer structure 1262 coupled thereto. At this time, the outer layer structure 1262 can smoothly rotate without moving the inner layer structure 1261 by the rolling of the balls 1263a of the ball layer structure 1263, and the inner layer structure 1261 and the first shaft portion 1221 connected thereto do not rotate. Therefore, when the user operates the first roller 122, the second roller 124 is not undesirably driven to rotate, and when the user operates the second roller 124, the first roller 122 is not undesirably driven to rotate. In other embodiments, the shaft connecting assembly 126 may be another type of bearing, or another suitable type of shaft connecting assembly, and the invention is not limited thereto.
Referring to fig. 3, in more detail, the first wheel portion 1222 and the second wheel portion 1242 of the present embodiment are sequentially arranged along a direction parallel to the rotation axis a1 and are close to each other, so that the fingers of the user can easily move from one of the first wheel portion 1222 and the second wheel portion 1242 to the other. In addition, the first wheel portion 1222 and the second wheel portion 1242 together form an accommodating space S, and at least a portion of the first shaft portion 1221, at least a portion of the second shaft portion 1241 and the shaft connecting component 126 are located in the accommodating space S, so that the configuration space outside the first wheel portion 1222 and the second wheel portion 1242 can be saved.
Fig. 4 is a perspective view of the magazine of fig. 2. In the present embodiment, the mouse body 110 includes a main housing 112 (shown in fig. 1) and a frame 114 (shown in fig. 2 to 4), the frame 114 is disposed in the main housing 112 and is used for carrying the roller module 120, and the roller module 120 is rotatably connected to the frame 114 through a first shaft 1221 thereof, for example. Further, the frame body 114 of the present embodiment is connected to the main housing 110 in a manner of being deflectable along the other rotation axis a2, for example, by the shaft structure 1141, so that the roller module 120 can be tilted along with the deflection of the frame body 114, thereby improving the flexibility and comfort of the user when operating the roller module 120. The axis of rotation a2 is, for example, substantially perpendicular to the axis of rotation a 1. Further, the wheel module 120 and the frame 114 can be integrated into a single module and then assembled to the main housing 112, so as to simplify the assembly of the mouse 100 and avoid too many assembly tolerances due to too complicated assembly processes.
In the embodiment shown in fig. 3, the shaft connection assembly 126 is configured to be positioned opposite the first wheel portion 1222. Accordingly, the second shaft portion 1241 connects the shaft connection assembly 126 by means of the stepped groove structure formed by the stop structure 1241a and the hollow portion 1241c as described above. However, the invention is not limited thereto. FIG. 5 is a cross-sectional view of a mouse according to another embodiment of the present invention. The embodiment of FIG. 5 differs from the embodiment of FIG. 3 in that in the roller module 120A of FIG. 5, the shaft connection assembly 126 is not to a first wheel portion 1222 of the first roller 122A but to a second wheel portion 1242 of the second roller 124A. Accordingly, in contrast to the embodiment shown in fig. 3, the second shaft portion 1241A of fig. 5 does not include the stop structure 1241A as shown in fig. 3, and the hollow portion 1241c of the second shaft portion 1241A extends directly from the inner wall of the second wheel portion 1242 to connect the shaft connection assembly 126. That is, the second shaft portion 1241A of fig. 5 has a smaller extension length than the second shaft portion 1241 of fig. 3 for connection to the shaft connecting assembly 126. Also, the first shaft portion 1221A has a stop structure 1221c on the periphery thereof, and the stop structure 1221c partially overlaps the shaft connecting assembly 126 in the axial direction of the shaft connecting assembly 126 (the direction parallel to the rotation axis a 1) to stop the shaft connecting assembly 126 at its position when the shaft connecting assembly 126 is unexpectedly disengaged from the hollow portion 1241 c. In the embodiment, a gap is formed between the stopping structure 1221c and the hollow portion 1241c, for example, to avoid resistance generated by contact friction between the stopping structure 1221c and the hollow portion 1241c when the first roller 122A and the second roller 124A rotate relatively. By configuring the axle connection assembly 126 to be positioned in the second wheel portion 1242 as shown in FIG. 5, the axle connection assembly 126 may be utilized to provide good support for the second roller 124.
In the embodiment shown in fig. 5, the shaft connecting component 126 is a ball bearing, however, the invention is not limited thereto. FIG. 6 is a cross-sectional view of a mouse according to another embodiment of the present invention. The embodiment of FIG. 6 differs from the embodiment of FIG. 5 in that the shaft connecting assembly 126A of FIG. 6 is a self-lubricating material, which may be in the form of a sleeve. When the first roller 122A rotates, the first shaft portion 1221A can smoothly rotate without the second shaft portion 1241A due to the low friction of the self-lubricating material. On the contrary, when the second roller 124A rotates, the second shaft portion 1241A can rotate smoothly without driving the first shaft portion 1221A by the low friction force of the self-lubricating material. Therefore, when the user operates the first roller 122A, the second roller 124A is not undesirably driven to rotate, and when the user operates the second roller 124A, the first roller 122A is not undesirably driven to rotate.
In the embodiment shown in fig. 3, the first shaft 1221 has a first pivot end 1221a and a second pivot end 1221b opposite to each other, and the roller module 120 is rotatably connected to the frame 114 of the mouse body 110 by the first pivot end 1221a and the second pivot end 1221 b. Specifically, the first pivoting end 1221a of the first shaft 1221 is rotatably connected to the frame 114 and the encoder (encoder)130 of the mouse, and the second pivoting end 1221b of the first shaft 1221 is rotatably connected to the frame 114. However, the invention is not limited thereto. FIG. 7 is a cross-sectional view of a mouse according to another embodiment of the present invention. The difference between the embodiment shown in fig. 7 and the embodiment shown in fig. 3 is that in the roller module 120B of fig. 7, the first shaft portion 1221B of the first roller 122B has a first pivot end 1221a, the second shaft portion 1241B of the second roller 124B has a second pivot end 1241B opposite to the first pivot end 1221a, and the roller module 120B is rotatably connected to the frame 114 of the mouse body 110 by the first pivot end 1221a and the second pivot end 1241B. Specifically, the first pivot end 1221a of the first shaft portion 1221B is rotatably connected to the frame 114 and the encoder 130, and the second pivot end 1241B of the second shaft portion 1241B is rotatably connected to the frame 114.
FIG. 8 is a cross-sectional view of a mouse according to another embodiment of the present invention. The embodiment shown in fig. 8 is different from the embodiment shown in fig. 7 in that in the roller module 120C of fig. 8, the shaft connecting assembly 126 is disposed around the second shaft portion 1241C of the second roller 124C, the first shaft portion 1221C of the first roller 122C includes a hollow portion 1221d, the hollow portion 1221d extends from the inner wall of the first wheel portion 1222 and is sleeved on the shaft connecting assembly 126, and the stopping structure 1241a of the second shaft portion 1241C partially overlaps the shaft connecting assembly 126 in the axial direction (the direction parallel to the rotation axis a 1) of the shaft connecting assembly 126 to stop the shaft connecting assembly 126 at its position when the shaft connecting assembly 126 is unexpectedly disengaged from the hollow portion 1221 d. That is, in the radial direction of the rotation axis a1, the first shaft portion 1221C, the shaft connection assembly 126, and the second shaft portion 1241C are arranged in this order from the outside toward the inside. In the present embodiment, a gap is formed between the stopping structure 1241a and the hollow portion 1221d, for example, to avoid a resistance generated by the contact friction between the stopping structure 1241a and the hollow portion 1221d when the first roller 122C and the second roller 124C rotate relatively.
The following describes a signal output manner of the wheel module according to an embodiment of the present invention. As shown in fig. 3, the mouse 100 (shown in fig. 1) further includes the encoder 130, and the encoder 130 is disposed in the mouse body 110 (shown in fig. 1) and connected to the first shaft 1221 of the first wheel 122, and is adapted to sense the rotation of the first shaft 1221. In addition, as shown in fig. 3, the mouse 100 (shown in fig. 1) further includes a non-contact sensor 140, for example, an optical sensor, which is disposed in the mouse body 110 (shown in fig. 1) and faces the second wheel 124, and is adapted to sense the rotation of the second wheel 124. Specifically, the second roller 124 may have a plurality of sensed portions 1242a at the second wheel portion 1242 thereof, and these sensed portions 1242a may be concave portions or other suitable forms, which are configured around the rotation axis a1 to be suitable for sequentially aligning with the optical sensors (the non-contact sensors 140) as the second roller 124 rotates. Thus, the optical sensor can obtain the rotation amount and the rotation speed of the second roller 124 by sensing the sensed portions 1242 a. In other embodiments, the sensed portion 1242a may be formed at other suitable positions of the second roller 124, and the contactless sensor 140 may be configured at other suitable positions to be suitable for sensing the sensed portion 1242a accordingly.
FIG. 9 is a cross-sectional view of a mouse according to another embodiment of the invention. The embodiment shown in fig. 9 is different from the embodiment shown in fig. 3 in that in the wheel module 120D of fig. 9, the non-contact sensor 140D is a magnetic sensor, which may be a Hall (Hall) sensor. The second roller 124D may have a plurality of magnetic portions 1242b at the second wheel portion 1242D, and these magnetic portions 1242b may be permanent magnets and arranged in a polarity staggered manner about the rotation axis a1 to be adapted to be sequentially aligned at the magnetic sensor (the non-contact sensor 140D) as the second wheel portion 1242D rotates. Thus, the magnetic sensor can obtain the rotation amount and the rotation speed of the second roller 124D by sensing the magnetic portions 1242 b. In other embodiments, the magnetic portion 1242b may be formed at other suitable positions of the second roller 124D, and the contactless sensor 140D may be configured at other suitable positions accordingly to sense the magnetic portion 1242 b.
The embodiments shown in fig. 5-8 are configured with the optical sensor (the non-contact sensor 140) and the corresponding sensed portion 1242a shown in fig. 3. However, the invention is not limited thereto, and the optical sensor (the non-contact sensor 140) and the corresponding sensed portion 1242a shown in fig. 5 to 8 may be replaced by the magnetic sensor (the non-contact sensor 140D) and the corresponding magnetic portion 1242b shown in fig. 9.
FIG. 10 is a block diagram of some of the components of the mouse of FIG. 1. Referring to fig. 10, further, the mouse 100 of the present embodiment further includes a determination unit 150, where the determination unit 150 is, for example, a determination circuit, which is disposed in the mouse body 110 (shown in fig. 1) and coupled to the non-contact sensor 140. When the user accidentally touches the second roller 124 while operating the first roller 122 to cause the second roller 124 to undesirably rotate, since the first roller 122 has a smaller rotation speed due to the mechanical action of the encoder 130, and the second roller 124 rotated by the user synchronously with the first roller 122 also has a smaller rotation speed, the non-contact sensor 140 senses that the rotation speed of the second roller 124 is less than the predetermined value, and the determining unit 150 determines that the rotation of the second roller 124 is a false operation. Therefore, the user can be prevented from mistakenly contacting the second roller 124 to output an unexpected signal when operating the first roller 122. The determining unit 150 can be applied to any of the embodiments shown in fig. 5 to 9.
FIG. 11 is a schematic diagram of a portion of the components of a mouse according to another embodiment of the invention. The embodiment of fig. 11 differs from the embodiment of fig. 3 in that the mouse in the embodiment of fig. 11 further comprises a support 160. The supporting member 160 is disposed in the frame 114 of the mouse body 110 and adapted to support the first roller 122 along a radial direction of the rotation axis a1, so as to prevent the roller module 120 from being damaged by a user's downward pressure on the roller module 120. Further, the supporting member 160 may be an idler wheel, which is rotatably disposed on the frame body 114. Due to the rotatable characteristic of the idler wheel (the support member 160), the resistance generated by the contact of the first roller 122 with the support member 160 during the rotation can be avoided.
