Description

Mouse with tilted scroll wheel coding mechanism

technical field

The invention relates to a wheel mouse, in particular to a mouse with an inclined wheel coding structure.

Background technique

When a user operates a computer through an input device such as a mouse or a keyboard, the user can often use a scroll wheel (scroll wheel) on the mouse or keyboard to generate a specific control signal, for example, when browsing a web page, the user only It is necessary to move the scroll wheel back and forth to make the webpage scroll up and down. However, not every picture (or picture) displayed on the computer screen can be completely browsed by scrolling up and down, because these pictures may also include parts that are not displayed on the left and right sides.

In order to allow the user to directly operate the scroll wheel to make the pages on the computer screen scroll horizontally, a scroll wheel module that can be tilted left and right is proposed and applied to input devices such as a mouse or a keyboard. Referring to FIG. 1 and FIG. 2 , it shows a perspective view of the appearance of a known mouse 1 provided with an inclined wheel module and a three-dimensional structural view of the inclined wheel module, wherein the wheel 12 of the inclined wheel module 11 is partially protruded The opening 101 of the mouse body 10 is provided for the user to operate; and the inclined wheel module 11 can not only allow the user to turn the wheel in a forward and backward manner (as shown in the direction of arrow F-B) to generate a control signal In addition, the user can also generate three other control signals by pressing down (as shown in the direction of arrow D) or moving the scroll wheel 12 left and right (as shown in the direction of arrow L-R).

Referring to FIG. 2 , it shows a perspective view of the inclined roller module 11 in FIG. 1 . First of all, the main components of the inclined roller module 11 include: a roller 12, a roller rotating shaft 13, a carrier 14, a support frame 15 with an accommodating portion 151, and three rollers arranged on the left and right sides of the carrier 14 and the carrier 14 respectively. Switch 16A, switch 16B, and switch 16C on the lower front. Wherein, a wheel axle accommodation portion 141 is formed on the carrier 14 to combine with the roller rotating shaft 13 and allow the roller 12 to be rotated in the carrier 14 .

Continuing to refer to FIG. 2, the inclined roller module 11 forms side wings 142A and side wings 142B on the left and right sides of the carrier 14, respectively, and arranges the switches 16A and 16B located on the left and right sides of the carrier 14 under the side wings 142A and 142B; The inclined roller module 11 also forms a protruding shaft 143A and a protruding shaft 143B at the front and rear ends of the carrier 14, wherein the protruding shaft 143A can be combined to the accommodating portion 151 of the support frame 15 and maintained in a rotatable state. The other protruding shaft 143B is placed directly on top of the switch 16C. In this way, when the user turns the roller 12 to the left or right, the carrier 14 can use the accommodating portion 151 of the support frame 15 and the top of the switch 16C as two fulcrums to swing to the left or right, and then the side wings 142A Or the side wing 142B triggers the switch 16A or switch 16B; and when the user presses the roller 12 downward, the protruding shaft 143B of the carrier 14 will use the accommodating portion 151 of the support frame 15 as a fulcrum to generate a downward displacement, thereby enabling Toggle switch 16C.

However, this known inclined roller module has the following problems. When the user does not operate the roller 12, the protruding shaft 143B of the carrier 14 only touches the top of the switch 16C, but does not trigger the switch 16C, and when the user presses down the roller 12, the protruding shaft 143B of the carrier 14 will trigger the switch 16C. But at this moment, the roller 12 and the carrier 14 are still in a state of being able to swing left and right; therefore, the user is easy to let the roller turn left or Tilting to the right makes the side wings 142A or 142B of the carrier 14 trigger the switch 16A or 16B, thus causing the mouse 1 to interrupt the control signal originally output, or output a control signal that the user did not expect.

In order to improve the deficiencies of the known tilting wheel module, the applicant filed a patent application in Taiwan, China No. 95100875 entitled "Input Device with Tilting Wheel Module" on January 10, 2006.

Please refer to FIG. 3 , which is a schematic diagram of China Taiwan Patent Application No. 95100875. The main feature of the No. 95100875 patent application for invention is that in the tiltable roller module 21, a pair of stoppers 27 and 28 that can be snapped together when combined are set under the carrier 24, which are used for when the user goes down When the roller 22 is pressed to trigger the switch 26C, the stopper 27 arranged on the carrier 24 also moves downward and then engages with another stopper 28, so that the carrier 24 can no longer move left or right. Swing, or reduce the degree to which the carrier 24 can swing left or right, so that the carrier 24 can no longer trigger other switches 26A or 26B. And when the user stops pressing the roller 22 downward, the carrier 24 will be pushed upward by the switch 26C and move upward. The carrier 24 returns to the original state where it can swing freely to the left or to the right.

Although the No. 95100875 invention patent application of Fig. 3 has solved the defect of the known inclined roller module shown in Fig. 2, yet, the inclined roller modules of Fig. 2 and Fig. 3 all need to be respectively provided with a switch and a switch on both sides of the roller. Mechanism design for triggering the switch. This makes the known tilting wheel module occupy a large volume when assembled into the mouse, and because there are many parts, it takes a lot of assembly time to install the trigger switch mechanism and switch to the correct position.

Therefore, there is a need for a mouse with a more simplified tilt-type scroll wheel coding structure.

Detailed ways

Please refer to FIG. 4 , which is an exploded view of a coding structure of a preferred embodiment of a mouse with an inclined scroll wheel coding structure according to the present invention.

FIG. 4 shows the bottom 200 of the mouse housing, the scroll wheel 201 , the scroll wheel seat 202 , the first support part 203 , the second support part 204 and the multi-directional switch 205 . The roller carrier 202 includes: two sidewalls 202A, 202B, a first end 2021 , a second end 2022 and a trigger arm 2023 having a groove 20231 (see FIG. 6 ).

In the embodiment of FIG. 4 , the roller carrier 202 further includes a horizontal rotating shaft 202C, and the first supporting portion 203 is a supporting piece having a concave portion 203A. In addition, in the embodiment of FIG. 4 , the roller carrier 202 further includes a vertical support piece 202D, and the second support portion 204 includes or is a limiting groove formed on the bottom 200 of the casing.

The constituent elements of the embodiment shown in FIG. 4 will be described in detail below. An accommodating space 202E is formed between the two sidewalls 202A and 202B of the roller carrier 202 for rotatably accommodating the roller 201 therein. The horizontal shaft 202C at the first end 2021 of the roller base 202 is disposed in the recess 203A of the first support portion 203 , and the vertical support piece 202D at the second end 2022 of the roller base 202 is inserted into the limiting groove. In addition, FIG. 4 also shows that an encoder holder 202B1 is disposed on the side wall 202B of the roller holder 202 for accommodating an encoder 202B2 therein.

The multi-directional switch 205 is disposed on a circuit board (not shown in this figure), and the trigger button 205A of the multi-directional switch 205 extends into the groove 20231 of the trigger arm 2023 of the roller carrier 202 .

Please refer to FIG. 5A and FIG. 5B , which are schematic diagrams of two embodiments of the multi-directional switch 205 . In the present invention, the multi-directional switch can be a three-way switch, as shown in FIG. 5A ; or a five-way switch, as shown in FIG. 5B . The characteristic of the three-way switch in Fig. 5A is that only the trigger button 205A' of the three-way switch 205' can be operated to generate three trigger signals. When the trigger button 205A' receives forces along the directions of arrows R1, R2 and R3, respectively, the three-way switch 205' will generate a first switch signal, a second switch signal and a third switch signal. When the external force disappears, the trigger button 205A' will return to the original position before no force is applied. In other words, a single three-way switch 205' can generate three switching signals, while the aforementioned known switch can only generate one trigger signal. FIG. 5B shows a five-way switch 206 . Same as the principle of the three-way switch 205' in FIG. 5A, as long as the trigger button 206A of the five-way switch 206 is tilted along the R1 direction, the R2 direction, the R3 direction, the R4 direction and the R5 direction, five switch signals can be generated.

Please refer to FIG. 6 , which is an assembly diagram of the encoding structure with inclined rollers in FIG. 4 . The operation diagram of the first embodiment of the encoding structure with inclined rollers of the present invention will be described below with reference to FIG. 4 and FIG. 6 .

The inclined scroll wheel coding structure is arranged inside a mouse, and the scroll wheel 201 partially protrudes from the surface of the mouse casing, so that the user can rotate the scroll wheel 201 with fingers.

When the user rotates the scroll wheel 201 , the mechanical encoder 202B2 located in the encoder holder 202B1 can be driven to generate a third-axis encoding signal, for example, to control the scrolling of the scroll bar on the screen. And when the user presses the roller 201 down, it will drive the roller carrier 202 to move downward, so that the trigger arm 2023 of the roller carrier 202 touches the trigger button 205A' of the three-way switch 205' (even if the trigger button 205A' is affected by R1 directional force) to generate a first switch signal. When the user turns the roller 201 in the R2 direction, the roller carrier 202 will take the limit groove as the fulcrum, and the length between the limit groove and the trigger arm 2023 (such as represented by D) as the radius, and move in the R2 direction. Swinging makes the trigger button 205A′ protruding into the groove 20231 of the trigger arm 2023 of the roller base 202 tilt in the R2 direction, thereby generating the second switch signal. Similarly, when the roller 201 is turned toward the R3 direction, the trigger button 205A' can be tilted toward the R3 direction, thereby generating a third switch signal.

In particular, the length of the swing radius D is related to the swing amplitude required for the roller carrier 202 to press the multi-directional switch 205 . For example, if there is another coding structure with a swing radius of D1, where D1>D, then in the case of D1, the roller carrier 202 can press the multi-directional switch 205 only with a small swing range.

Of course, a five-way switch may also be used instead of the three-way switch. In the case of using a five-way switch, five switch signals can be generated by operating the roller 201 .

It can be understood from the above description that, compared with the known inclined roller structure, the present invention only needs one multi-directional switch to realize the function of the known inclined roller structure, and does not produce the known problem of using three one-way switches. The problem of accidentally touching the switch.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the scope of patent protection of the present invention. Therefore, all other equivalent changes or modifications completed without departing from the spirit disclosed in the present invention shall include In the following patent protection scope.
