Description

Technical Field

[0001] The utility model belongs to the technical field of electronic device accessories, and particularly relates to an auxiliary touch button and an electronic device protective case. Background Art

[0002] With the development of technology, the functions of electronic devices such as mobile phones and tablets are increasing day by day, and the buttons for controlling corresponding functions are also developed accordingly; for example, a capture button named CaptureButton is installed on the newly released iPhone 16 of Apple Inc. This capture button has a capacitive touch surface and uses advanced capacitive technology to sensitively identify the user's touch force and gesture changes, thereby triggering different photography functions. Specifically, it includes: half-press for focusing, full-press for shooting, sliding for zooming, long-press for video recording, etc. A series of complex operations are simplified to one finger, making photography more intuitive and efficient.

[0003] Currently, the capture button is embedded in the frame of the electronic device, and there is no auxiliary touch control for extending the capture button on the market. Therefore, users must touch the frame of the electronic device when using it, which makes the capture button lose its function in some special cases; for example, in order to protect the electronic device, most electronic devices are equipped with a protective case. However, since the traditional protective case does not have a corresponding auxiliary touch control for the capture button, the capture button cannot be used normally, bringing great trouble to users. Therefore, it is very necessary to design an auxiliary touch button and an electronic device protective case to solve the above problems. Summary of the Utility Model

[0041] Refer to the attached Figure 1 and the attached Figure 2 and the attached Figure 5 and the attached Figure 9 and 16 and , an auxiliary touch button for use in conjunction with the capture button 10 of the electronic device 1, which includes an insulating key block 2 and conductive columns 3; the insulating key block 2 can be arranged outside the frame of the electronic device 1, and the bottom surface of the insulating key block 2 corresponds to and fits the touch surface 100 of the capture button 10; there are multiple conductive columns 3 which are arranged at intervals on the insulating key block 2, and the leading ends of the multiple conductive columns 3 extend to the top surface of the insulating key block 2, and the trailing ends of the multiple conductive columns 3 extend to the bottom surface of the insulating key block 2 and synchronously fit multiple contacts on the touch surface 100.

[0042] Specifically, when in use, the auxiliary touch button is installed at the frame of the electronic device 1, and the bottom surface of the insulating key block 2 corresponds to and fits the touch surface 100 of the capture button 10. Multiple array-designed and charged contacts are arranged on the touch surface 100. Since the trailing ends of the multiple conductive columns 3 synchronously fit multiple contacts on the touch surface 100, the charges at the contacts will be transmitted through the bodies of the multiple conductive columns 3 to the leading ends of the multiple conductive columns 3, that is, the multiple conductive columns 3 can be regarded as multiple independent charge transfer channels, and then multiple charged points are formed at the top surface of the insulating key block 2.

[0043] When the user's finger touches the corresponding charged position, under the action of the human body electric field, a coupling capacitor is formed between the user's finger and the capture button 10 to trigger the corresponding contact point on the touch surface 100; if the finger slides on the top surface of the insulating key block 2, when the finger disconnects the old contact point, the new contact point is connected, so as to realize the sliding touch control of the capture button 10, and then adjust the camera to zoom in or out.

[0044] In addition, if the auxiliary touch control button is movably arranged on the frame of the electronic device 1, when the user presses the insulating key block 2, the capture button 10 can also be driven, so that functions such as half-press focusing, full-press shutter, sliding zoom, and long-press video recording of the capture button 10 can be used normally.

[0045] In summary, the utility model designs the insulating key block 2 to correspondingly fit the capture button 10, and installs a plurality of mutually spaced conductive columns 3 inside the insulating key block 2 to form a plurality of mutually independent charge transfer channels, so that the charges at the contact points of the touch surface 100 can be transferred to the top surface of the insulating key block 2 through each charge transfer channel, thus facilitating the user to use the finger for touch control; therefore, the design of the auxiliary touch control button solves the problem that the capture button 10 cannot be extended for use and improves the user experience.

[0046] It should be noted that regarding the installation method of the auxiliary touch control button, an adhesive layer (not shown in the figure) or an adsorption layer (not shown in the figure) corresponding to the touch surface 100 can be provided on the bottom surface of the insulating key block 2, which is convenient for the user to directly bond or adsorb the insulating key block 2 to the insulating button for use. At this time, the insulating key block 2 serves as an external functional button protruding from the frame of the electronic device 1, which is convenient for the user to touch and avoids the user accidentally touching the capture button 10, improving the usability; on the other hand, the auxiliary touch control button can also be installed on an external game handle (not shown in the figure), so that after the electronic device 1 is installed on the external game handle, the user can still normally touch and use the capture button 10 when playing games; in addition, the auxiliary touch control button can also be installed on an electronic device protection case such as a mobile phone case or a tablet case for use, so that after the electronic device 1 is installed in the protection case, the user can still normally touch and use the capture button 10. This case can be referred to in the following text; since the actual use scenarios of the auxiliary touch control button are diverse and the fixing methods are also diverse, the utility model does not limit this, and the above embodiments are only for reference and understanding.

[0047] Regarding the capture button 10, it belongs to the prior art. Its touch surface 100 uses capacitive sensing technology and has multiple charged contacts. Currently, the capture button 10 is only used on the new mobile phone iPhone 16 released by Apple, but it is not excluded that it may be applied to electronic devices 1 such as tablets and watches in the future. And currently, the capture button 10 is only used to control the camera shooting function of the mobile phone, but it is not excluded that other control programs will be set up for combined use in the future. For example, it can be designed to slide the capture button 10 up and down to slide short videos, or control music track switching, etc. Therefore, this auxiliary touch button is only used to extend the use of the capture button 10, and there are no restrictions on the usage scenarios and control functions of the capture button 10.

[0048] Refer to the attached Figure 1 - attached Figure 4 , and the attached Figure 9 , the insulating key block 2 is made of any one of PC, ABS, PC + ABS, PE, PA, PET, and PP. These materials have good insulation performance and can effectively prevent the charge of the capture button 10 from being transferred to the insulating key block 2 and interfering with the conductive column 3. In addition, there are many other insulating materials, which are not listed one by one in this utility model, but other insulating materials can be regarded as conventional replacements in this application.

[0049] Refer to the attached Figure 1 - attached Figure 4 , and the attached Figure 9 , the conductive column 3 is made of any one of copper, copper alloy, aluminum alloy, conductive plastic, and conductive rubber. These materials have good electrical conductivity and can smoothly transfer the charge of the capture button 10 to form multiple stable charge points on the top surface of the insulating key block 2 for users to touch. In addition, there are many other conductive materials, which are not listed one by one in this utility model, but other conductive materials can be regarded as conventional replacements in this application.

[0050] Refer to the attached Figure 1 - attached Figure 4 , regarding the arrangement of multiple conductive columns 3, there are various ways, which are not restricted in this utility model. For the convenience of understanding, the following embodiments are exemplified here:

[0051] Embodiment 1

[0052] Multiple conductive columns 3 are linearly arrayed on the key block to orderly correspond to multiple contacts of the touch surface 100. This design can not only make the touch button more beautiful as a whole but also have the effect of prompting the user's sliding direction, improving the user's experience. The specific style is as shown in the attached Figure 1 and the attached Figure 3 .

[0053] Embodiment 2

[0054] Multiple conductive posts 3 are randomly distributed on the key block to disorderly correspond to multiple contacts of the touch surface 100. This design allows the multiple conductive posts 3 to be randomly interspersed, which is convenient for combining various irregular patterns on the top surface of the insulating key block 2, improving the interestingness. The styles of the specific patterns are diverse, and corresponding diagrams are not given here.

[0055] Refer to Appendix Figure 1 Appendix Figure 3 Appendix Figure 9 Refer to Appendix

[0056] Appendix Figure 2 Appendix Figure 4 Appendix Figure 9 Refer to Appendix

[0057] Appendix Figure 6 - Appendix Figure 15 Refer to Appendix

[0058] Specifically, during use, the electronic device 1 is installed in the accommodation cavity 40 and the capture button 10 is aligned with the notch 400, so that the bottom surface of the insulating key block 2 and the tails of the multiple conductive posts 3 can normally contact and fit the touch surface 100 of the capture button 10. At this time, the charges of the multiple contacts of the touch surface 100 can be smoothly transferred to each conductive post 3 without interference, and finally form charged points on the top surface of the insulating key block 2, enabling the user to normally slide and touch the capture button 10 located inside the housing 4 outside the housing 4.

[0059] It should be noted that regarding the installation method of the assistive touch button, in addition to installing the assistive touch button on the protective case of the electronic device for use, the assistive touch button can also be installed on external peripherals such as an external game controller for use. The specific situation has been mentioned many times above and will not be described in detail here.

[0060] Refer to the appendix Figure 10 - Appendix Figure 15 , actually, if only the sliding zoom function of the capture button 10 needs to be used, the insulating key block 2 is fixedly installed at the notch 400, so that multiple conductive posts 3 can more stably fit the touch surface 100 of the capture button 10, thereby realizing sliding touch control; but if the sliding zoom, half-press focus, full-press shutter, long-press video recording and other functions of the capture button 10 are used at the same time, it is necessary to ensure that the insulating key block 2 has a certain range of movement when installed at the notch 400 to facilitate driving the capture button 10; for this reason, in the present utility model, a guide block 4000 is provided on the inner wall of the notch 400, and a guide groove 20 is provided on the side wall of the insulating key block 2. The guide groove 20 is slidably matched with the guide block 4000, so that the insulating key block 2 can move relative to the notch 400, and the capture button 10 can be driven by pressing the insulating key block 2.

[0061] Specifically, when the electronic device 1 is installed in the accommodation cavity 40, the bottom surface of the insulating key block 2 and the tails of multiple conductive posts 3 are attached to the touch surface 100 of the capture button 10. At this time, the guide block 4000 is located at the topmost side of the guide groove 20, so that the insulating key block 2 is restricted and fixed at the notch 400; and because the guide block 4000 is slidably matched with the guide groove 20, the assistive touch button can move along the guide groove 20. Therefore, when the user presses the insulating key block 2, the capture button 10 will be correspondingly driven to realize functions such as half-press focus, full-press shutter, and long-press video recording.

[0062] Refer to the appendix Figure 10 - Appendix Figure 16 , the present utility model further includes a diaphragm 5. The diaphragm 5 is arranged at the notch 400 and is located between the insulating key block 2 and the capture button 10, and the diaphragm 5 is attached to the touch surface 100 and the bottom ends of the conductive posts 3; the thickness of the diaphragm 5 is h, and the capacitance sensing range of the touch surface 100 is d, and h < d.

[0063] Specifically, the design of the diaphragm 5 can prevent the insulating key block 2 and the conductive posts 3 from directly contacting and scratching the touch surface 100, and has a certain protective effect; but considering that the diaphragm 5 itself does not have the ability to conduct electricity, in order to avoid the diaphragm 5 hindering the transfer of charges to the conductive posts 3, it is necessary to ensure that the thickness h of the diaphragm 5 is less than the capacitance sensing range d of the touch surface 100; the specific working principle can refer to the appendix Figure 16 , after the diaphragm 5 is attached to the touch surface 100, the charge can still pass through the diaphragm 5 and be transferred to the finger. Here, the finger is replaced by the conductive post 3, and the charge can be transferred to the conductive post 3.

[0064] Therefore, when h < d, the capture button 10 can still be used normally.

[0065] Refer to the appendix Figure 12 - Appendix Figure 15 As shown in the figure, the housing 4 includes a base housing 41 and a cover plate 42. The accommodating cavity 40 and the notch 400 are provided on the base housing 41, and the base housing 41 is further provided with a mounting groove 410 on the side wall of the accommodating cavity 40 that communicates with the notch 400; the diaphragm 5 is fixed in the mounting groove 410 and closes the notch 400, and the diaphragm 5 is made of a flexible material with waterproof ability; the cover plate 42 is mounted on the base housing 41 and closes the accommodating cavity 40, so that the electronic device 1 is in a closed space.

[0066] Specifically, with this structural design, the housing 4 has a waterproof function, enabling the user to normally view the screen of the electronic device 1 in water and use the capture button 10 to control the camera shooting function of the electronic device 1, facilitating the user to take pictures or record videos underwater.

[0067] Furthermore, there are various types of flexible materials with waterproof ability, such as flexible plastics like TPU and PVC. The present utility model does not limit this.

[0068] It should be noted that the sealing design of the base housing 41 and the cover plate 42 is clearly described in the existing waterproof cases of electronic devices 1 and belongs to the prior art. Therefore, the present utility model does not elaborate further on this; the diaphragm 5 can be fixed in the mounting groove 410 by glue bonding. Since the diaphragm 5 is flexible, when the user presses the insulating key block 2, the diaphragm 5 can undergo adaptive deformation without detaching from the mounting groove 410, ensuring that the insulating key block 2 can normally drive the capture button 10.

[0069] It should also be noted that although the embodiments of the present application have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present application.
