Description

Input device and method for manufacturing the same

Technical Field

The present invention relates to an input device and a method for manufacturing the same, and more particularly, to an input device having a switch and a method for manufacturing the same.

Background

Many input devices, such as keyboards, mice, touch pads, trackballs, and optical scanners, are widely used to operate electronic devices. In order to input commands conveniently, intuitively, and quickly, most of the input devices used are mice. As shown in fig. 4, the mouse mainly includes a housing 1001, a micro-switch 1002 provided in the housing, a mouse button 1003 provided on the top of the housing, and a key shaft 1004 protruding from the bottom of the mouse button 1003 toward the micro-switch 1002. When a user clicks a mouse button, the key shaft 1004 touches the microswitch 1002 to input a command to the electronic device.

Ideally, manufacturers would like to produce a mouse in which the key shaft would just touch but not activate the micro-switch when the user did not hit the mouse key. However, in the conventional mouse, the key shaft is easily formed with a manufacturing tolerance, so that the actual length of the key shaft is too long or too short. In addition, assembly tolerance is easy to generate between the mouse button and the shell. Therefore, when the mouse button is assembled with the housing, the button shaft is prone to have a problem of idle stroke or pre-compression. The problem of idle stroke refers to that after assembly, a gap exists between the key shaft and the micro switch, so that when a user clicks a mouse button, the key shaft moves downwards for an idle stroke and then contacts the micro switch, rather than directly triggering the micro switch to input an instruction; the problem of pre-pressing is that the micro-switch is normally kept pressed by the key shaft after assembly, that is, the micro-switch is pressed down by the key shaft in a natural state, so that the mouse is too sensitive and a user can easily input an instruction by mistake. The idle stroke and the pre-pressure will cause the reduction of the product yield and affect the smooth operation of the user. One current practice of manufacturers is to measure each mouse after assembling the mouse to check whether there is an idle stroke or pre-compression problem, and if so, disassemble and readjust the mouse and then reassemble the mouse again until the idle stroke or pre-compression phenomenon is eliminated. The assembly, measurement, disassembly and reassembly method causes the manufacturing and production efficiency of the mouse to be low.

Disclosure of Invention

In view of the above problems, the present invention discloses an input device and a method for manufacturing the same, which is helpful for solving the problem that the conventional key shaft generates idle stroke or preload.

The manufacturing method of the input device disclosed by the invention comprises the following steps of: providing a main body, wherein the main body comprises a shell part and a switch part arranged in a cavity defined by the shell part; a cover body is provided, wherein the cover body comprises a pressed piece, a contact piece and an elastic fixing piece. The contact element is directly connected with the pressure-bearing piece, or the contact element is connected with the pressure-bearing piece through the elastic fixing piece; the cover body is arranged on the main body, wherein one part of the pressed piece is arranged on the shell piece, and the other part of the pressed piece is arranged in the cavity. The contact piece is directly connected with the other part or connected with the other part through an elastic fixing piece; adjusting the relative position between the contact piece and the pressed piece so that the contact piece just contacts the switch piece; and fixing the relative position between the pressure receiving member and the contact member by the elastic fixing member.

The input device disclosed by the invention comprises a main body and a cover body. The main body comprises a shell part and a switch part arranged in a cavity defined by the shell part. The cover body comprises a pressed piece, a contact piece and an elastic fixing piece. The elastic fixing piece is used for fixing the relative position between the pressure-bearing piece and the contact piece, so that the contact piece just contacts the switch piece. One part of the pressure piece is arranged on the shell piece, and the other part of the pressure piece is arranged in the cavity. The contact piece is directly connected with the other part or connected with the other part through the elastic fixing piece, and the contact piece just contacts the switch piece.

According to the input device and the manufacturing method thereof disclosed by the invention, the cover body of the input device comprises the elastic fixing piece for fixing the relative position between the pressure-receiving piece and the contact piece. When the cover body is arranged on the main body, the contact piece can move relative to the pressed piece and just contact the switch piece. Finally, the relative position between the pressure piece and the contact piece is fixed through an elastic fixing piece. Therefore, the axial length of the whole pressed part and the contact part can be adjusted through the movement of the elastic fixing part and the contact part, so that the problem of idle stroke or prepressing is avoided, the product yield can be improved, and the operation smoothness of a user can be improved.

In the method for manufacturing the input device disclosed in an embodiment of the present invention, if the elastic member and the blocking member are used as the elastic fixing member, before the assembly, an opening is formed in one side surface of the housing, the opening is suitable for the blocking member to extend into the cavity surrounded by the housing through the opening, the elastic member is connected between the pressure receiving member and the contact member, and the components are combined with each other.

Therefore, by adopting the input device and the manufacturing method thereof provided by the embodiment of the invention, the key shaft is formed or fixed when being completely assembled, so that the height of the key shaft is completely matched with the switch piece below the key shaft, the idle stroke or prepressing condition is prevented, and a feasible scheme is provided for improving the use experience of a user; in addition, the complicated processes of assembly, measurement, disassembly and reassembly, which are the same as those of the traditional manufacturing method, are not needed, so that the manufacturing and production efficiency of the input device is improved.

The detailed features and advantages of the present invention are described in detail below by embodiments, which are sufficient for anyone skilled in the art to understand the technical contents of the present invention and to implement the present invention, and the related objects and advantages of the present invention can be easily understood by anyone skilled in the art according to the disclosure of the present specification, the patent protection scope and the accompanying drawings. The following examples further illustrate aspects of the present invention in detail, but are not intended to limit the scope of the invention in any way.

Fig. 1A is a schematic cross-sectional view of an input device according to a first embodiment of the invention. In the present embodiment, the input device 1 includes a main body 10, a cover 20, and a curable material 30. The input device 1 may be a computer mouse or a computer keyboard, for example. In the present embodiment, the input device 1 is exemplified by a computer mouse.

The main body 10 includes a housing member 110 and a switch member 120 disposed in a cavity defined by the housing member 110. The switch member 120 is, for example, a micro switch of a computer mouse, and has a switch contact contacting the contact member 220. In addition, the main body 10 may further include a circuit board, a roller, an LED lamp and a sensor, which are disposed in the cavity 111 of the casing 110 and electrically connected to the switch 120, but the configuration of these elements is not intended to limit the present invention. Fig. 1A only shows the switch member 120, and other elements of the main body 10 disposed in the casing member 110 are not shown.

The cover body 20 includes a pressure receiving member 210 and a contact member 220 connected to the pressure receiving member 210. The pressure receiving member 210 is partially disposed on the housing member 110 of the main body 10, and partially disposed in the cavity defined by the housing member 110, and a contact member 220 rotatably connected to the portion contacts the switching member 120 of the main body 10. Specifically, the pressure receiving member 210 includes a pressure receiving portion 211 and a connecting portion 212 protruding from the pressure receiving portion 211 toward the switch member 120. The pressed portion 211 is, for example, a key of a computer mouse, the connecting portion 212 is, for example, a portion of a key shaft of the computer mouse, and the contact 220 is, for example, another portion of the key shaft of the computer mouse. The pressure receiving portion 211 is disposed on the housing member 110 of the main body 10, and the contact 220 is connected to one end of the connecting portion 212 remote from the pressure receiving portion 211. When the curable material 30 is not yet added, the area of the portion where the contact 220 is connected to the connection portion 212 is small, and deformation may occur. In detail, the cross-sectional area W1 of at least a part of the connection portion 212 gradually decreases toward the contact 220 along the axial direction thereof to the connection point P of the contact 220 at the connection portion 212, and the cross-sectional area W2 of the contact 220 gradually decreases toward the connection portion 212 along the axial direction thereof to the connection point P. The function of the above structure will be described in detail later.

The pressed member 210 is, for example, a left button or a right button of a computer mouse, and the connecting portion 212 and the contact member 220 are, for example, a key shaft of the computer mouse. When the user does not press the pressure receiving member 210, the contact member 220 connected to the pressure receiving member 210 abuts and contacts the switching member 120. When the user presses the pressure receiving portion 211 of the pressure receiving member 210, the contact member 220 presses the trigger switch member 120, so that the input device 1 generates an input command.

The curable material 30 is an elastic material, and may be, for example, a photo-curable material such as a photosensitive resin (Photopolymer), a thermal-curable material such as silicone (organic silicon), a quick-drying adhesive, or a combination thereof. The curable material 30 is disposed at a connection portion 212 of the pressure receiving member 210 of the cover body 20 and the contact member 220.

The following describes a method of manufacturing the input device 1 of the present embodiment. Please refer to fig. 1B to fig. 1F. FIG. 1B is a flowchart illustrating steps of a method of manufacturing the input device of FIG. 1A. Fig. 1C to 1F are schematic views illustrating a process of manufacturing the input device of fig. 1A.

First, step S1 is executed to provide the main body 10 and the cover 20. The main body 10 and the cover 20 can be manufactured by plastic injection molding, for example. At this time, the main body 10 is provided to include the housing member 110 and the switch member 120, and the cover 20 includes the pressure receiving member 210 and the contact member 220, wherein the connection between the pressure receiving member 210 and the contact member 220 is not cured, for example, the contact member 220 of the cover 20 is movably connected to the pressure receiving member 210 at this time. At this stage, the area of the portion where the contact 220 is connected to the connection portion 212 is small, and deformation may occur. In detail, the contact 220 of the present embodiment is integrally connected to the pressure receiving member 210, and the contact 220 can rotate relative to the pressure receiving member 210 with the connection point P as a rotation center.

Next, step S2 is executed to dispose the curable material 30 in an uncured state at the connection portion 212 and the contact 220. In detail, step S2 may include the following steps: as shown in fig. 1C and fig. 1D, two adhesive members 2 are disposed on two opposite sides of the contact member 220, so that the connection portion 212 of the pressure receiving member 210, the contact member 220 and the adhesive member 2 together form a receiving space 40 near the connection portion 212 and the contact member 220; then, the uncured curable material 30 is disposed in the accommodating space 40, so that the area of the portion where the connecting portion 212 is connected with the contact 220 is increased due to the presence of the curable material; finally, the adhesive element 2 can be selectively removed.

After the step S2, the step S3 is performed to install the cover 20 on the main body 10. In detail, step S3 may include the following steps: as shown in fig. 1E, the pressure receiving member 210 is disposed on the outer shell 110; next, as shown in fig. 1F, the relative position of the contact member 220 and the pressure receiving member 210 is adjusted, so that the contact member 220 moves relative to the pressure receiving member 210 to just contact the switch member 120. In the present embodiment, the relative positions of the contact member 220 and the pressure receiving member 210 are adjusted by the way of the stationary main body 10 and the cover body 20. Since the curable material 30 is not cured yet and has a certain fluidity, the contact member 220 can be rotated by its own weight relative to the connection portion 212 of the pressure receiving member 210 to hang down and contact the switch member 120. By resting the main body 10 and the cover 20, it is helpful to ensure that sufficient time is provided for the contact member 220 to just contact the switch element 120 before proceeding with the subsequent manufacturing steps. In other embodiments, the contact member 220 can be manually rotated to adjust the relative position of the contact member 220 and the pressure receiving member 210, so that the contact member 220 just contacts the switch member 120. The term "just touch" as used herein means that the contact member 220 just touches the switching element 120 without displacing the switching element.

Finally, step S4 is performed to fix the relative position between the pressure receiving member 210 and the contact member 220. Step S4 may include the following steps: and curing the curable material 30 arranged on the pressure receiving member 210 and the contact member 220. In detail, if the curable material 30 includes a photo-curable material, the curable material 30 may be cured by external light or by using an LED lamp (not shown) disposed on the housing member 110; if the curable material 30 comprises a thermosetting material, the entirety of the input device 1 may be heated to cure the curable material 30; if the curable material 30 includes the quick-drying adhesive, the main body 10 and the cover 20 may be continuously left standing after step S3 is performed, until the curable material 30 is completely cured. When the curable material 30 is cured, the contact 220 can no longer rotate relative to the connection portion 212, and thus the axial length L (shown in fig. 1F) of the connection portion 212 and the contact 220 as a whole is fixed.

In summary, according to the input device 1 and the manufacturing method thereof disclosed in the present embodiment, the cover 20 of the input device 1 includes the contact member 220 movably disposed on the pressure receiving member 210 before the assembly is completed. When the cover 20 is disposed on the main body 10, the contact member 220 can move relative to the pressure receiving member 210 to just contact the switch member 120. When the contact member 220 just contacts the switching member 120, the curable material 30 is cured to fix the relative position between the pressure receiving member 210 and the contact member 220. Therefore, when the curable material 30 is not cured, the axial length L of the connection portion 212 and the contact member 220 can be adjusted by the movement of the contact member 220, so as to avoid a gap between the contact member 220 and the switch member 120, thereby preventing the cover 20 from generating an idle stroke after being disposed on the main body 10, and improving the yield of products and the smoothness of operations of users.

In the present embodiment, the step S2 of disposing the uncured curable material 30 on the pressure receiving member 210 and the contact element 220 is earlier than the step S3 of disposing the cover 20 on the main body 10. Therefore, the curable material 30 can be arranged before the pressure receiving member 210 and the contact member 220 are covered by the shell member 110 of the main body 10, which helps to reduce the manufacturing difficulty.

Furthermore, in the present embodiment, the step S2 includes providing the adhesive member 2 to form the accommodating space 40 suitable for accommodating the uncured curable material 30. Thereby, the adhesive member 2 helps to suitably restrict the flow direction of the uncured curable material 30, avoiding that the curable material 30 sticks to other components of the input device 1 during the setting process. After the flowability of the settable material 30 is slightly reduced (e.g., standing for a part of the fluid components in the settable material 30 to volatilize), the adhesive element 2 can be selectively removed.

In addition, in the present embodiment, the cross-sectional area W1 of the connection portion 212 of the pressure receiving member 210 gradually decreases toward the contact 220 along the axial direction thereof to the connection point P of the contact 220 with the connection portion 212, and the cross-sectional area W2 of the contact 220 gradually decreases toward the connection portion 212 along the axial direction thereof to the connection point P. Thereby, the sectional area of the connecting portion 212 and the contact 220 at the connecting point P can be reduced, and the contact 220 can be more easily rotated and hung down with respect to the connecting portion 212 by its own weight.

In the first embodiment, the axial length of the whole of the pressure-receiving member and the contact member is adjusted by moving the contact member, and the curable material is used to fix the relative position between the pressure-receiving member and the contact member, so as to solve the problem of idle stroke. For example, the contact member 220 may be precisely contacted with the switch member 120 by measuring, for example, a precise instrument, and the curable material 30 may be cured, thereby helping to prevent the pre-pressing phenomenon and improving the use experience of the input device. Please refer to fig. 2A to fig. 2C. Fig. 2A is a schematic cut-away view of an input device according to a second embodiment of the invention. Fig. 2B to 2C are schematic diagrams illustrating the manufacturing of the input device of fig. 2A. Since the second embodiment is similar to the first embodiment, only the differences will be described below.

In the present embodiment, as shown in fig. 2B, the contact member 220 of the cover body 20 contacts the switch member 120 of the main body 10 before the pressure receiving member 210 is disposed on the housing member 110. As shown in fig. 2C, when the step of disposing the pressure-receiving member 210 on the housing member 110 is continuously performed, the moving path below the contact 220 is stopped by the switch member 120, so that the contact 220 rotates relative to the connecting portion 212 of the pressure-receiving member 210 to adjust the relative positions of the contact 220 and the pressure-receiving member 210, and the axial length L of the connecting portion 212 and the contact 220 is shortened. Finally, the curable material 30 is cured to fix the axial length L. Therefore, the input device and the manufacturing method thereof disclosed in the embodiment help to prevent the contact element 220 from normally pressing the switch element 120 when the user is not in use, thereby avoiding the pre-pressing condition, and improving the product yield and the operation smoothness of the user.

In the first and second embodiments, the structure and connection relationship of the pressure receiving member 210, the contact member 220 and the curable material 30 are not intended to limit the present invention. Please refer to fig. 3A to fig. 3C. Fig. 3A is a schematic cut-away view of an input device according to a third embodiment of the invention. Fig. 3B to 3C are schematic diagrams illustrating the manufacturing of the input device of fig. 3A. Since the third embodiment is similar to the first embodiment, only the differences will be described below.

In the present embodiment, the cover 20 of the input device 1 ″ includes the pressure receiving member 210 and the contact member 220 ″. The contact member 220 "has a groove 221" on a side facing the connection portion 212 of the pressure receiving member 210. One end 2121 of the connecting portion 212 remote from the pressure receiving portion 211 is located inside the groove 221 ", and the end 2121 is separated from the groove wall surface of the groove 221". The curable material 30 is disposed within the recess 221 "and covers the end 2121 of the connection 212.

As shown in fig. 3B and 3C, in the manufacturing method of the present embodiment, an uncured curable material 30 is first disposed in the groove 221 ″; then, the pressure receiving member 210 is disposed on the housing member 110, and the main body 10 and the cover 20 are placed still, so that the contact member 220 ″ moves relative to the pressure receiving member 210 to just contact the switch member 120. Since the curable material 30 is not cured yet and has a certain fluidity, the contact member 220 ″ can hang down against the connection portion 212 of the pressure receiving member 210 by its own weight and just contact the switch member 120.

Finally, the curable material 30 disposed in the groove 221 "of the contact 220" is cured to fix the relative position between the pressure receiving member 210 and the contact 220 ". Therefore, a gap between the contact member 220 ″ and the switch member 120 can be prevented, which helps to prevent an idle stroke after the cover 20 is disposed on the main body 10. The present embodiment is provided to solve the idle stroke problem, but the invention is not limited thereto. In other embodiments, the contact member 220 "contacts the switching member 120 before the pressure receiving member 210 is disposed on the housing member 110. When the pressure receiving member 210 is further disposed on the housing member 110, the contact member 220 "is moved upward relative to the connecting portion 212 to make the end 2121 extend into the groove 221", so that the axial length of the connecting portion 212 and the contact member 220 "is shortened. The curable material 30 is then cured to fix the relative positions of the connection 212 and the contact 220 "so that the contact 220" just contacts the switch member 120. Thus, the contact 220 "in combination with the curable material 30 also solves the pre-compression problem.

In summary, in the input device and the manufacturing method thereof disclosed in the present invention, the cover of the input device includes the contact member movably disposed on the pressure receiving member. When the cover body is arranged on the main body, the contact piece can move relative to the pressed piece to contact the switch piece. The curable material is cured to fix the relative position between the pressure receiving member and the contact. Therefore, when the curable material is not cured, the axial length of the whole of the pressed part and the contact part can be adjusted through the movement of the contact part, so that the problem of idle stroke or prepressing is avoided, the product yield can be improved, and the operation smoothness of a user can be improved.

Although the embodiments of the present invention have been disclosed, they are not intended to limit the present invention.
