Description

Electronic device and its buttons

The invention relates to an electronic device and its keys.

The keys of the existing electronic device usually include one or more independent sub-keys, a rubber block under each sub-key, and a rotating shaft provided under each sub-key to fix the sub-key to the electronic device. The button rotating shaft is usually fixed directly below the button, so when the user presses the button to complete the input, when the pressing button is near the center, there is a situation that there is no touch or a bad touch, that is, the feel of the button is around the rotating shaft. There is a button touch zone in the area. Therefore, the user will repeatedly press the button.

In view of this, it is necessary to provide a button with better touch to solve the above problem.

It is also necessary to provide an electronic device having a better tactile sensation to solve the above problems.

An electronic device includes a housing having an opening and a button portion secured within the opening. The button portion includes a plurality of buttons, a fixing portion for fixing the button to the housing, and a rubber strip engaged with the button. The fixing portion includes a connecting portion connected to the button at both ends of the button portion, a sleeve connected to the connecting portion, and a rotating shaft that fixes the button to the housing through the sleeve.

The present invention also provides a button that is fixed to a housing of an electronic device. The button includes a plurality of sub-buttons, a fixing portion for fixing the button to the housing, and a rubber strip engaged with the button. The rubber strip is in the form of an elongated strip. The fixing portion includes a connecting portion connected to the sub-buttons at both ends of the button, a bushing connected to the connecting portion, and a rotating shaft passing through the bushing and fixed to the housing.

The electronic device and the button provided by the invention cooperate with the button by providing an integrally formed rubber strip to form a button with a long cantilever structure, so that the button of the electronic device has a better tactile sensation.

Referring to FIGS. 1 and 2 , the electronic device 99 includes a housing 100 having an opening 101 , a button 200 received in the opening 101 and fixed to the housing 100 . The button 200 includes a plurality of sub-buttons, a rubber strip 210 disposed under the button 200 and coupled to the sub-button 200 and fixed to the housing 100, and a fixing portion 220 for fixing the sub-button to the housing 100. Among them, the number of buttons can be set according to actual needs.

In the present embodiment, the button 200 includes four sub-keys, that is, a first button 201, a second button 202, and two third buttons 203 symmetrically disposed at two ends of the second button 202. The electronic device 99 is an electronic book, the first button 201 is a home button, the second button 202 is a page down button, and the two third buttons 203 are all page-up keys, and the page turning function can be completed through the above buttons. . In addition, in the case that the e-book also has other functions, such as music playing, the above buttons can also perform corresponding control of other functions, such as adjusting the volume of music playing. In other embodiments, the electronic device 99 may also be a music player, a mobile phone, etc., and the number and function of the buttons may be set as needed.

The fixing portion 220 includes a connecting portion 2221, a sleeve 2220, and a rotating shaft 2222. The connecting portion 2221 is provided with a positioning hole 2224, and the two ends thereof are respectively connected to the third button 203 and the sleeve 2220. The sleeve 2220 is provided with a through hole through which the rotating shaft 2222 passes.

Referring to FIG. 2 and FIG. 3 together, the lower surfaces of the first button 201, the second button 202, and the third button 203 are each provided with a groove 204 and a protrusion 205 is protruded from the bottom of the groove 204. The rubber strip 210 is an integrally formed strip shape, and the lower surface of the four buttons is matched with the four buttons: the corresponding groove 204 is provided with a protrusion 2104, and the corresponding protrusion 205 is provided with a recess 2105. A plurality of lugs 2106 are also provided on both side edges of the rubber strip 210.

Two positioning members 102 and two fixing members 103 respectively located on two sides of the opening 101 are protruded from the inner surface of the housing 100. The positioning member 102 passes through the positioning hole 2224 of the fixing portion 220. The fixing member 103 passes through the rotating shaft 2222 and fixes the rotating shaft 2222, thereby fixing the button 200 to the housing 100.

When assembling, the bump 2104 on the rubber strip 210 and the groove 204 of the button, the recess 2105 and the protrusion 205 are aligned, and the rubber strip 210 is assembled with the button (as shown in FIG. 4), and then the rubber strip 210 is assembled. The fixing portion 220 passes through the opening 101, and the rotating shaft 2222 passes through the sleeve 2220 to fix the button 200 to the housing 100. The lug 2106 on the rubber strip is then overlapped with a plurality of holes in the inner surface of the housing 100, and the rubber strip 210 is fixed to the housing 100 by screws or the like passing through the holes in the lug 2106 and the housing 100.

In use, due to the long cantilever structure adopted by the button 200, the rotating shaft 2222 of the button is disposed at both ends of the button 200, and cooperates with the button through the integrally formed rubber strip 210, so that the user presses the first button 201, the second button 202, and Any position on the third button 203 has a good tactile sensation.

In addition, those skilled in the art can make other changes in the spirit of the present invention. Of course, the changes made in accordance with the spirit of the present invention should be included in the scope of the present invention.
