Description

Mouse structure capable of regulating roller actuating force

Technical Field

The present invention relates to a mouse structure, and more particularly to a mouse structure capable of preventing a user from touching a micro switch by mistake due to too much force for moving a roller.

Background

Along with the development of science and technology, the popularity of computers is increasing, and most of the work and entertainment are related to computers, wherein a mouse is an essential important accessory when people operate computers, the basic structure of the mouse is provided with a sensor (such as a sensing mechanism formed by a traditional rolling ball and a rotating shaft, or an optical recognition mechanism popularized in recent years) at the bottom, and two keys at the top are provided for users to change the cursor position on the computer screen and input corresponding instructions, and a roller is also usually provided on the mouse, so that the users can intuitively and conveniently perform finer control (such as scrolling pictures) on the computer by shifting the roller.

For the office workers who need to use the computer for a long time, or users such as electronic competition game players, besides paying attention to the hand feeling of pressing the keys, the scroll wheel is also the most commonly used component of computer users, for example, the scroll wheel is shifted to browse the web page or move the cursor, or the scroll wheel is pressed to output signals to switch different function modes, so the quality of the pressing hand feeling of the mouse keys and the sensitivity of the scroll wheel after being shifted are the key of selecting the mouse, however, in the process of quickly shifting the mouse scroll wheel by the user, the situation of generating error messages due to improper force application is easy to occur, so how to effectively solve the above problems to meet the harsh requirements of the consumers on electronic products is an important subject to be solved by the present application.

SUMMERY OF THE UTILITY MODEL

In view of the above-mentioned shortcomings of the conventional mouse structure, after repeated research, testing and refinement, the applicant finally developed a mouse structure capable of adjusting the actuating force of the roller, and the application is expected to effectively solve the above-mentioned problems and form the required conductive portion by spraying.

In order to solve the above technical problem, a technical solution adopted in the present application is to provide a mouse structure capable of adjusting an actuating force of a roller, wherein the mouse structure includes a housing, a circuit board, a supporting seat, a roller module, and a gasket.

Optionally, a first groove is disposed on the top side of the other end of the support seat, and the mouse structure further includes a cover and a first elastic component. The cover body is arranged in the shell, and at least a local area of the cover body can be positioned above the top surface of the first groove. The first elastic component is located between the first groove and the cover body.

Optionally, two sides of the supporting seat are respectively provided with a second pivot hole, the roller module is provided with a pivot shaft, and two ends of the pivot shaft can respectively extend into the second pivot holes, so that the roller module can be pivoted to the supporting seat.

An annular space is arranged in the roller, the pivot shaft is positioned in the annular space, and the roller is pivoted to the supporting seat through the pivot shaft. The roller frame is sleeved on the roller, and the local area of the roller frame can be exposed out of the shell from the roller opening.

Optionally, the roller module further comprises: an assembly member, a pushing member, at least one second elastic member and a ball. The assembly part is provided with a through hole at two opposite side surfaces, the assembly part can extend into the annular space, so that the pivot shaft can pass through the through hole, the assembly part is pivoted to the roller, and at least one assembly space is concavely arranged at the top side of the assembly part. The top side of the pushing piece is provided with a second groove. The second elastic component is positioned between the assembly part and the pushing part, and the pushing part can be displaced in a direction away from the assembly part by the action force generated by the second elastic component. The ball is arranged in the second groove.

Optionally, a plurality of grooves are recessed in an inner side surface of the roller, a tooth portion is formed between each two adjacent grooves, the grooves and the tooth portions can be exposed out of the annular space, and when the assembly member, the second elastic element, the pushing member, and the ball are assembled in the roller, the ball is pressed against one of the grooves under the influence of the acting force of the second elastic element.

The present application is a mouse structure capable of adjusting the actuating force of a roller, wherein the present application is mainly designed for the relevant structure of a roller module 14, and therefore, the following description will not additionally describe the relevant mechanisms of a left button 101 and a right button 102 of the mouse structure 1, and the left/

right buttons

101 and 102 can follow the existing button structure of the mouse (for example, the left/

right buttons

101 and 102 can respectively trigger corresponding micro switches after being pressed). For convenience of explanation, the following embodiments use the upper side of fig. 1 as the top side (upper) position of the component, the lower side of fig. 1 as the bottom side (lower) position of the component, the upper left of fig. 1 as the front side position of the component, and the lower right of fig. 1 as the rear side position of the component. Referring to fig. 1 and fig. 2, in one possible embodiment of the present application, the mouse structure 1 includes a housing 11, a circuit board 12, a supporting base 13 and a roller module 14, wherein the housing 11 has a receiving space therein for receiving components required by the normal operation of the mouse structure 1.

In summary, referring to fig. 1 and fig. 2, the housing 11 at least includes a base 111 and an outer cover 112, wherein the circuit board 12, the supporting base 13 and the roller module 14 can be disposed on the base 111, the outer cover 112 is disposed with a roller opening 1121, the roller opening 1121 is communicated with the accommodating space, the outer cover 112 can cover a top side of the base 111 to shield the circuit board 12 and the supporting base 13, and a local area of the roller module 14 can be exposed out of the roller opening 1121. In addition, one end (front end) of the supporting base 13 is pivoted to the base 111, and the other end (rear end) thereof extends toward the rear side of the base 111, so that the supporting base 13 can rotate around the one end thereof as an axis, so that the other end thereof can move up and down. Referring to fig. 2 and 3, in the embodiment, two opposite sides of one end of the supporting base 13 are respectively provided with a fixing shaft 131 protruding outwards, one end (front end) of the base 111 is provided with two first pivot holes 1111, and each fixing shaft 131 can respectively extend into each first pivot hole 1111, so that the supporting base 13 can be pivoted to the base 111, that is, the supporting base 13 can use the front end thereof as a supporting point, and the rear end thereof can freely move up and down. Referring to fig. 3, a micro switch 15 is disposed on the circuit board 12, the micro switch 15 is electrically connected to the circuit of the circuit board 12, and the micro switch 15 corresponds to the other end of the supporting base 13.

Furthermore, referring to fig. 1 to fig. 3, the roller module 14 is pivotally connected to the supporting base 13, and a local area of the roller module is exposed out of the outer cover 112 from the roller opening 1121, so that the roller module 14 can be rotated or pressed downward by a user, in this embodiment, two sides of the supporting base 13 are respectively provided with a second pivot hole 132, the roller module 14 is provided with a pivot shaft 1421, two ends of the pivot shaft 1421 can respectively extend into the second pivot holes 132, so that the roller module 14 can be pivotally connected to the supporting base 13, that is, the roller module 14 can be rotated by being stirred with the pivot shaft 1421 as a supporting point. Moreover, when the roller module 14 is pressed downward by a user, the roller module 14 can drive the other end of the supporting base 13 to move downward, so as to directly or indirectly press and activate the micro switch 15 (described in detail later) through the supporting base 13, so that the micro switch 15 can send a corresponding touch signal through a circuit on the circuit board 12.

When the user dials the wheel module 14, especially when the user dials the wheel module 14 quickly with a finger, the wheel module 14 will be subjected to a downward force, so that, in order to prevent the wheel module 14 from touching the micro switch 15 by mistake and generating an error signal due to an excessive dialing force, a gasket 16 (as shown in fig. 3) is disposed between the supporting base 13 and the micro switch 15, wherein the gasket 16 is made of an elastic material (such as silica gel) to have an elastic restoring force, and when the gasket is deformed by an external force, the gasket restores its original shape due to the elastic restoring force when the external force is removed. Here, referring to fig. 3 to 6, in the embodiment, a protruding part 135 is protruded downward from the bottom side of the other end of the supporting base 13, a button 151 is protruded upward from the top side of the micro switch 15, an opening is opened on the top side of the spacer 16, and a space is formed therein, the opening is communicated with the space, the protruding part 135 can extend into the space through the opening, so that the spacer 16 can be fixed on the protruding part 135 in an inserting manner, but not limited thereto, in other possible embodiments of the present application, the spacer 16 can be fixed on the supporting base 13 in other manners. Alternatively, the pad 16 can be bonded or otherwise secured to the surface of the microswitch 15 not corresponding to the button 151.

In this embodiment, the middle portion of the bottom end of the pad 16 is in an upward concave configuration, the bottom end of the middle portion is adjacent to two opposite sides and can abut against the top side of the micro switch 15, and the key 151 can correspond to the concave configuration of the pad 16 (as shown in fig. 4), when the pad 16 is fitted (engaged) on the convex member 135, the length of the convex member 135 can be adjacent to, the same as, or exceed the concave configuration of the pad 16, when the roller module 14 is not pressed downward, the convex member 135 does not press the key 151, but when the roller module 14 is pressed downward and the force of the downward pressing is greater than the elastic restoring force of the pad 16, the roller module 14 can drive the other end of the supporting seat 13 to move downward, so that the pad 16 is pressed by the supporting seat 13 to deform, the bottom edge of the convex member 135 and/or a partial bottom edge of the pad 16 can press the key 151, the micro switch 15 is pressed by the protrusion 135 and/or the pad 16 to generate a signal. However, in other possible embodiments of the present application, when the pad 16 is engaged (embedded) in the protruding portion 135, the length of the protruding portion 135 can be shorter, so that the key 151 is only pressed by the pad 16, when the roller module 14 is not pressed, a partial bottom edge of the pad 16 does not press the key 151, but when the roller module 14 is pressed downward and the force of the pressing downward is greater than the elastic restoring force of the pad 16, the roller module 14 can drive the other end of the supporting base 13 to move downward, so that the pad 16 is pressed by the supporting base 13 to deform, and the partial bottom edge of the pad 16 can press the key 151, so that the micro switch 15 is pressed by the pad 16 to generate a signal.

In addition, in other possible embodiments of the present application, the other end of the supporting base 13 can be provided with no protruding member 135, the middle portion of the bottom end of the gasket 16 can be provided with an upward concave configuration for accommodating the key 151, the bottom end of the gasket 16 adjacent to the two opposite sides can be adhesively fixed on the surface of the micro switch 15 not corresponding to the key 151, and the bottom edge of the gasket 16 can not touch the key 151 when the roller module 14 is not pressed; however, when the roller module 14 is pressed downward, the roller module 14 can drive the other end of the supporting base 13 to move downward, so that the pad 16 is pressed by the supporting base 13 to deform, and a local bottom edge of the pad 16 can touch the button 151, so that the micro switch 15 is touched by the pad 16 to generate a signal.

Moreover, when the roller module 14 is no longer pressed downward, the pad 16 will generate a restoring force to force the supporting base 13 to move upward, so that the micro switch 15 is no longer pressed by the protrusion 135 and/or the pad 16, thus, although a user pulls the roller module 14, a part of downward component force is applied to the roller module 14, the component force is not enough to overcome the elastic restoring force of the pad 16, and therefore, when the user pulls the roller module 14, the micro switch 15 can be prevented from being triggered by the roller module 14 by mistake. In addition, in a state where the mouse structure 1 is operated by a user, the pad 16 can also reduce the vibration generated after the wheel module 14 is toggled or pressed, so that the operation of the mouse structure 1 can be more stable.

Referring to fig. 3 to 6, in the embodiment, a first groove 134 is formed at the top of the other end of the supporting seat 13, a cover 18 is disposed in the housing 11, at least a partial region of the cover 18 can be located above the top surface of the first groove 134 (to avoid the complicated drawings of fig. 5 and 6, the cover 18 is omitted in fig. 5 and 6), a fixing member 1341 is disposed in the first groove 134 in a protruding manner, one end (bottom end) of a first elastic member 17 extends into and is fixed to the fixing member 1341, and the other end (top end) of the first elastic member 17 abuts against the cover 18, so that the first elastic member 17 is accommodated between the first groove 134 and the cover 18, and when a user presses the roller module 14 first and then does not press the roller module 14 any more, the other end of the supporting seat 13 is influenced by the restoring force of the gasket 16 and moves upward, moreover, after the first elastic component 17 is compressed by the action force of the upward displacement of the other end of the supporting seat 13, its own elastic restoring force (i.e., restoring to the position before the deformation) can make the other end of the supporting seat 13 displace downward, so that the other end of the supporting seat 13 can be kept stable by the action force of the first elastic component 17 and the gasket 16, and no excessive shaking amplitude is formed, therefore, the vibration generated by the user stirring or pressing the roller module 14 can be absorbed by the first elastic component 17 and the gasket 16, and the actuation of the mouse structure 1 can be more stable.

Referring to fig. 2, 7 and 8, in this embodiment, the mouse structure 1 can use the wheel decoder of the existing mouse to determine the rotating amplitude and the rotating direction of the wheel module 14, when the user dials the wheel module 14, the wheel module 14 can use the wheel decoder to determine the rotating speed thereof, further calculate the actual rotating amplitude and confirm the rotating direction of the wheel module 14, and then generate the wheel operation signal according to the determined rotating amplitude and rotating direction, but the above features are not the focus of this application, and are not described herein. In addition, the roller module 14 includes a roller 142 and a roller frame 143, the roller 142 has an annular space 1420, a plurality of grooves 1422 are recessed in an inner side of the roller 142, a tooth 1423 is formed between two adjacent grooves 1422, the grooves 1422 and the tooth 1423 are exposed in the annular space 1420, the pivot 1421 is located in the annular space 1420, so that the roller 142 can be pivoted to the supporting base 13 via the pivot 1421, the roller frame 143 is sleeved on an outer side of the roller 142 and can be exposed out of the housing 11, so that a user's finger can move the exposed roller frame 143. In addition, the roller module 14 further includes an assembly member 141, a pushing member 144, at least one second elastic element 145 and a ball 146, wherein two opposite side surfaces (left and right side surfaces) of the assembly member 141 are formed with a through hole 1411, and a top side thereof is recessed with at least one assembly space 1412, the assembly member 141 can extend into the annular space 1420, so that the pivot 1421 can pass through the through hole 1411, and the assembly member 141 can be pivotally connected to the roller 142.

In view of the above, referring to fig. 2, fig. 7 and fig. 8, the second elastic element 145 can be located between the assembly member 141 and the pushing member 144, in this embodiment, one end (bottom side) of the second elastic element 145 can extend into and abut against the inner bottom surface of the assembling space 1412, the other end (top side) thereof can be connected to the bottom surface of the pushing member 144, the top side of the pushing member 144 is further provided with a second groove 1440, the ball 146 can be disposed in the second groove 1440, when the assembly member 141, together with the second elastic element 145, the pushing member 144 and the ball 146, is assembled in the roller 142, the pushing member 144 can be influenced by the force of the second elastic element 145 to displace in a direction away from the assembly member 141, so that the ball 146 can be located in one of the grooves 1422.

To explain the foregoing features in detail, referring again to fig. 2, 7 and 8, in the embodiment, in a state where the assembly member 141 is assembled into the roller 142, the ball 146 can be indirectly pressed in one of the grooves 1422 by the elastic force provided by the second elastic element 145, when the user pushes the wheel module 14, the force overcomes the force applied by the second elastic element 145 to the ball 146, such that the teeth 1423 adjacent to the groove 1422 can push the ball 146 to retract (i.e., the ball 146 moves toward the pivot 1421) until the ball 146 passes the current teeth 1423, and then is influenced by the force of the second elastic element 145, and extends into another groove 1422, so that the user can feel the touch of the section generated by rotation when dialing the roller module 14, for example: the user feels a stop every time the wheel module 14 rotates one scale. In addition, when the user does not pull the roller module 14 any more, since the force applied to the ball 146 by the teeth 1423 is smaller than the force indirectly applied to the ball 146 by the second elastic element 145, the ball 146 is pressed against the groove 1422 without displacement, and thus the roller module 14 can be reliably and stably stopped at the current position. In particular, the teeth 1423 of the present application are tapered, so that when the roller module 14 stops rotating, if the ball 146 exactly corresponds to the teeth 1423, since the contact area between the ball 146 and the teeth 1423 is small, the ball 146 indirectly affected by the force of the second elastic element 145 will slide into the groove 1422, so as to ensure that the ball 146 can stably stay in the groove 1422.

The above description is only an alternative embodiment of the present application, and not intended to limit the scope of the claims of the present application, so that all the modifications that can be made by those skilled in the art without inventive changes in the technical content disclosed in the present application are all included in the scope of the claims of the present application.
