Description

key structure

technical field

The invention relates to a key structure, in particular to a key structure of a portable electronic device.

Background technique

In electronic devices, for the fixed structure of buttons used to provide functions (such as power buttons, voice buttons, or wireless transmission buttons, etc.), the common way is to set positioning columns on the casing, and set positioning holes on the buttons. After the positioning column is inserted into the positioning hole, the keys are fixed to the casing by thermal melting. However, when the heat fusion is not correct, the key may be sunken in the casing, which will make the key unable to be pressed smoothly and affect the function opening and closing of the electronic device. In addition, if the casing and buttons are fixed by thermal fusion, a jig is required to align the desired thermal fusion area.

Detailed ways

FIG. 1 is a schematic diagram of a key structure applied to a portable electronic device according to an embodiment of the present invention. Please refer to FIG. 1 , in the present embodiment, the button structure 100 is suitable for a portable electronic device 10 , such as a notebook computer. The button structure includes a casing 110 and a button 120 . When the user presses the button 120 , the function of the electronic module (not shown) corresponding to the button 120 can be turned on or off.

FIG. 2 is a partial perspective view of the button structure in FIG. 1 . FIG. 3 is a partial perspective view of the button structure of FIG. 2 at another viewing angle. FIG. 4 is an exploded view of the button structure in FIG. 1 . Please refer to FIG. 2 , FIG. 3 and FIG. 4 , the housing 110 has a first slot 112 , a second slot 114 and a locking portion 116 . The button 120 has a pressing portion 122 , a connecting portion 124 and a sliding portion 126 , wherein the connecting portion 124 and the sliding portion 126 are located on two sides of the pressing portion 122 , and the pressing portion 122 is inserted into the first slot 112 . The sliding portion 126 is inserted into the second slot 114 , and the thickness of the sliding portion 126 adjacent to the pressing portion 122 is smaller than the thickness of the sliding portion 126 away from the pressing portion 122 .

In detail, when the assembler needs to assemble the button 120 to the casing 110, only the sliding part 126 of the button 120 is inserted into the second slot 114 of the casing 110, and the pressing part 122 of the button 120 is inserted into the second slot 114 of the casing 110. In the first slot 112 of the housing 110, finally snap the buckle part 116 of the housing 110 to the connecting part 124 of the button 120 to complete the assembly of the housing 110 and the button 120, wherein the sliding The portion 126 is, for example, a tongue structure. In this way, compared with the conventional key structure using hot-melt method, the button structure 100 not only has the advantages of easy assembly, but also does not require hot-melt jigs, thus reducing the cost of the portable electronic device 10 . In addition, the thickness of the sliding portion 126 adjacent to the pressing portion 122 is smaller than the thickness of the sliding portion 126 away from the pressing portion 122, that is, the thickness of the sliding portion 126 adjacent to the pressing portion 122 is smaller than the thickness of the sliding portion 126 away from the pressing portion 122, so It can be used as a weakening structure of the sliding part 126 to reduce the strength of a part of the sliding part 126 . When the sliding part 126 starts to deform, it will start to bend and deform at the weakened structure. In this way, the sliding portion can have better elasticity, which is helpful for the key 120 to be installed on the housing 110 , and can reduce the force exerted on the key 120 , so as to be convenient for the user to press.

FIG. 5 is a cross-sectional view of the casing of FIG. 3 along the section line I-I. FIG. 6 is a cross-sectional view of the button in FIG. 5 under a force-bearing state. Please refer to FIG. 4 , FIG. 5 and FIG. 6 , the second slot 114 of the casing 110 in this embodiment has a guiding surface 114 a, and the sliding portion 126 of the button 120 abuts against the guiding surface 114 a. The sliding part 126 is adapted to slide along the guiding surface 114a. Furthermore, when the user applies force to the pressing part 122, the sliding part 126 slides on the guiding surface 114a along a first direction d1 until the pressing part 122 touches the electronic module, and the sliding part 126 stops sliding (eg Figure 6). Conversely, when the user does not apply force to the pressing portion 122, the sliding portion 126 slides on the guiding surface 114a along a second direction d2 until the pressing portion 122 is completely inserted into the first slot 112 and abuts against the housing. 110 of the bottom surface 110a (as shown in FIG. 5 ), wherein the first direction d1 and the second direction d2 are inclined relative to the normal direction d3 of the bottom surface 110a of the housing 110, and the first direction d1 and the second direction d2 are mutually for the opposite direction. Therefore, the key 120 can move stably relative to the housing 110 by guiding the sliding portion 126 to slide through the guiding surface 114 a.

In addition, the buckle portion 116 of the housing 110 in this embodiment has a base portion 116a and a hook portion 116b. The base portion 116 a is erected on the bottom surface 110 a of the casing 110 , and the hook portion 116 b is connected to the base portion 116 a and extends toward the connection portion 124 . Furthermore, the connecting portion 124 has a first portion 124a and a second portion 124b. The first part 124 a connects the second part 124 b and the pressing part 122 . The hook portion 116b presses against the second portion 124b. When the pressing part 122 is pressed, the first part 124a of the part is driven by the pressing part 122, so that the first part 124a of the part is slightly deformed, wherein the first part 124a of this embodiment is, for example, an elastic arm structure. With this configuration, the key 120 can be pressed more easily without affecting the engagement between the connecting portion 124 of the key 120 and the buckle portion 116 of the casing 110 .

In addition, the pressing portion 122 and the connecting portion 124 of this embodiment are substantially parallel to the bottom surface 110a of the casing 110, and the sliding portion 126 extends from the bottom of the pressing portion 122, extends toward the second direction d2, and is inserted into the second slot. 114 inside. Therefore, the thickness of the sliding part 126 gradually increases along the second direction d2 after extending from the bottom of the pressing part 122 . In this way, the sliding portion 126 can form a structure with better elasticity.

Please refer to FIG. 1 , FIG. 2 and FIG. 4 , the button structure 100 of this embodiment further includes an upper cover 130 disposed on the casing 110 . The upper cover 130 has a third opening 132 at a position corresponding to the pressing portion 122 of the button 120 . When the upper cover 130 is assembled to the casing 110 , the pressing portion 122 of the button 120 is exposed through the third opening 132 . Therefore, the button 120 is located between the upper cover 130 and the casing 110 .

To sum up, in the present invention, the buckle portion of the housing is used to engage the connecting portion of the key, and the sliding portion of the key is inserted into the second slot of the housing to complete the assembly of the key and the housing. Therefore, compared with the conventional button structure using hot-melt method, the button structure of the present invention not only has the advantages of easy assembly, but also does not need hot-melt jigs, thus reducing the cost of the portable electronic device. In addition, the thickness of the sliding part adjacent to the pressing part is smaller than the thickness of the sliding part away from the pressing part, which can be used to reduce the strength of a part of the sliding part so that the sliding part starts to bend and deform from the weakened structure, so as to facilitate the button to be installed on the casing, and The user's effort can be reduced. Furthermore, when the second slot of the casing has a guiding surface, the sliding part is guided to slide by the guiding surface, so that the button can move stably relative to the casing.

Although the present invention has been disclosed above with the embodiments, it is not intended to limit the present invention, and any person of ordinary skill in the art may make some changes and modifications without departing from the spirit and scope of the present invention.
