[0028] In order to more clearly understand the above-mentioned objectives, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application can also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present application, not all of the embodiments.

[0030] The present application provides an electronic device, including but not limited to tablet electronic devices and foldable electronic devices. Tablet electronic devices include but are not limited to tablet phones, tablet personal computers, tablet laptop computers, tablet personal digital assistants (PDAs), tablet vehicle-mounted devices, and tablet wearable devices.

[0032] The side key wiring structure of the embodiment of the present application is described below.

[0033] See also Figure 1-Figure 3 , Figure 1 This is a schematic diagram of the side key wiring structure provided in some embodiments of the present application. Figure 2 This is an exploded view of the side key wiring structure provided in some embodiments of the present application. Figure 3A partial schematic diagram of a side key wiring structure provided in some embodiments of the present application. The side key wiring structure 100 provided in the embodiment of the present application may include a front housing body 1, a wiring component 2, and an injection molded component 3.

[0034] A first wiring groove 11 may be provided on the bottom wall of the front shell body 1. When there are multiple side keys, the extending direction of the first wiring groove 11 may be the same as the length direction of the front shell body 1.

[0035] A button hole 13 may be provided on the side wall of the front shell body 1 , and the button hole 13 may be used to connect the internal space of the electronic device with the outside.

[0036] For example, the front shell body 1 may be substantially formed in an “L” shape, and the side walls of the front shell body 1 may extend upward from the bottom wall.

[0037] The button hole 13 is connected to the first wiring groove 11. There can be multiple button holes 13, and the multiple button holes 13 can be arranged at intervals on the side wall of the front shell body 1.

[0038] Exemplarily, when there are multiple button holes 13, the first wiring groove 11 may include multiple spaced-apart first wiring sub-grooves, and one first wiring sub-groove may correspond to one button hole 13, so that the wiring harness can be separated, making the wiring harness layout of the side key wiring structure 100 more reasonable.

[0039] The wiring member 2 may include a pressing portion 21 and a connecting portion 22. The pressing portion 21 may pass through the key hole 13. Specifically, the pressing portion 21 is positioned opposite the key hole 13, with a portion of the pressing portion 21 located inside the key hole 13 and the remaining portion located outside the key hole 13.

[0040] The wiring portion 22 may be located in the first wiring groove 11. Specifically, a wiring harness may be provided in the wiring portion 22, and the wiring portion 22 may be electrically connected to a mainboard of the electronic device through the connecting portion 23.

[0041] The injection molded part 3 can be connected to the front shell body 1 and is used to cover the first wiring groove 11 and the button hole 13. Specifically, in the height direction of the front shell body 1, the first wiring groove 11 is located within the orthographic projection of the injection molded part 3 on the plane where the first wiring groove 11 is located, and in the width direction of the front shell body 1, the button hole 13 is located within the orthographic projection of the injection molded part 3 on the plane where the button hole 13 is located. Therefore, the injection molded part 3 can be connected to the inner side wall and bottom wall of the front shell body 1 and cover the first wiring groove 11 and the button hole 13, thereby preventing water from flowing into the interior of the electronic device through the button hole 13 or the upper portion of the front shell body 1, thereby facilitating improved waterproof performance of the electronic device.

[0042] According to the side key wiring structure 100 of the embodiment of the present application, a first wiring groove 11 is provided on the bottom wall of the front shell body 1, a button hole 13 is provided on the side wall, the button hole 13 is connected to the first wiring groove 11, and the connecting portion 22 of the wiring member 2 is provided in the first wiring groove 11, so that the pressing portion 21 passes through the button hole 13, and the injection molded part 3 covers the button hole 13 and the first wiring groove 11, so that the wiring member 2 can be connected to the front shell body 1 through the injection molded part 3, so that the wiring member 2 can be covered by the injection molded part 3, which can prevent water from flowing into the wiring member 2, and further avoid the use of soft or hard boards for carrying wiring, which is beneficial to reducing the cost of the electronic device. At the same time, the injection molded part 3 can prevent water from flowing into the electronic device from the button hole 13 or the upper part of the front shell body 1, thereby improving the waterproof performance of the electronic device.

[0043] Please continue reading Figure 1 In some embodiments, the wiring member 2 and the front housing body 1 can be integrally formed. The wiring member 2 and the front housing body 1 can be connected by ribs before injection molding, and the ribs can be removed by CNC after injection molding. The wiring member 2 and the front housing body 1 do not need to be connected and can be directly in-mold into the interior of the electronic device.

[0044] This helps improve the manufacturing efficiency of electronic devices and reduces the number of flexible or rigid boards carrying wiring, thereby reducing material costs.

[0045] It should be noted that the wiring component 2 and the front shell body 1 can also be formed separately, and this application does not impose any restrictions on this.

[0046] Please continue reading Figure 1 In some embodiments, the top of the button hole 13 may have an opening 131. The injection molded part 3 may be provided with the opening 131. The pressing portion 21 may be connected to the inner wall of the button hole 13 through the injection molded part 3. Specifically, the "top" refers to the side of the button hole 13 away from the bottom wall in the height direction of the front shell body 1. Part of the injection molded part 3 may cover the top of the side wall of the front shell body 1, and may pass through the opening 131 to enter the button hole 13, so that the injection molded part 3 may cover the opening 131 and may fill the space between the pressing portion 21 and the button hole 13.

[0047] This increases the width of the waterproof surface of the front housing body 1 and better prevents water from flowing in through the key holes 13, thereby reducing the water ingress path and improving the waterproof performance of the electronic device. Furthermore, the provision of the injection molded part 3 facilitates the connection between the front housing body 1 and other components of the electronic device, thereby improving the assembly efficiency of the electronic device.

[0048] Please continue reading Figure 1In some embodiments, the side key wiring structure 100 may further include a metal dome switch 4. The metal dome switch 4 may be connected to the pressing portion 21. The metal dome switch 4 may also be referred to as a dome switch, i.e., a metal dome conductive film. It may be a thin sheet containing a metal dome and may be used as a switch on a flexible circuit board such as a PCB or FPC. This may improve the service life of the side key wiring mechanism and reduce the manufacturing cost of the side key wiring structure 100.

[0049] Please continue reading Figure 1 In some embodiments, a positioning groove 14 may be formed on the side of the button hole 13 away from the first wiring groove 11. The metal dome 4 may be disposed in the positioning groove 14. This helps to reduce the difficulty of assembling the metal dome 4, facilitates assembly of the metal dome 4, and thus improves the assembly efficiency of the electronic device.

[0050] For example, when part of the injection molded part 3 is located on the top of the side wall of the front shell body 1 , the injection molded part 3 and the front shell body 1 may jointly define a positioning groove 14 .

[0051] Please continue reading Figure 1 In some embodiments, the key hole 13 is provided with an exhaust groove. The exhaust groove is located within the orthographic projection of the pot piece 4 on the plane where the key hole 13 is located. Thus, the reliability of the use of the pot piece 4 can be ensured.

[0052] Please continue reading Figure 1 In some embodiments, the side key wiring structure 100 may further include a waterproof membrane 5. The waterproof membrane 5 may be disposed on the outer side of the front housing 1 and cover the key holes 13. The provision of the waterproof membrane 5 further enhances the waterproofing of the electronic device while also ensuring a superior user experience.

[0053] Exemplarily, the waterproof membrane 5 may be a Mylar sheet.

[0054] Please continue reading Figure 1 In some embodiments, a second wiring groove 12 may be provided on the inner sidewall of the front housing 1. The second wiring groove 12 may communicate with the key hole 13. The connection portion 22 may be located within the first wiring groove 11, while the remaining portion may be located within the second wiring groove 12. This allows for full utilization of the structural space and a more rational layout of the side key wiring structure 100.

[0055] Please continue reading Figure 1In some embodiments, a connecting groove 15 may be provided on the bottom wall of the front shell body 1. One end of the first wiring groove 11 is connected to the button hole 13, and the other end is connected to the connecting groove 15. The wiring member 2 also includes a connecting portion 23, which is arranged in the connecting groove 15 and is connected to the connecting portion 22. Specifically, one end of the connecting portion 22 is connected to the pressing portion 21, and the other end is connected to the connecting portion 23, and the connecting portion 23 can be connected to the motherboard of the electronic device. In this way, the layout of the side key wiring structure 100 can be made more reasonable, so that the wiring of the side key can be more conveniently connected to the motherboard.

[0056] The injection molded part 3 can cover the connection groove 15. Thus, the connection portion 23 can be connected to the front shell body 1 through the injection molded part 3, and water can also be prevented from entering the connection portion 23, which is beneficial to improving the waterproof performance of the electronic device.

[0057] The surface of the connecting portion 23 away from the front housing body 1 is exposed to the injection molded part 3. This arrangement can prevent the injection molded part 3 from affecting the connection between the connecting portion 23 and the main board.

[0058] It should be noted that, in the description of the embodiments of the present application, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Among them, "fixed connection" means that the two are connected to each other and the relative position relationship after connection remains unchanged. In addition, the directional terms mentioned in the embodiments of the present application, such as "inside" and "outside", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present application, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application.

[0059] The foregoing is merely a list of specific embodiments of the present application, intended to enable those skilled in the art to understand and implement the present application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application.
