Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to an electronic equipment. Background Art

[0002] With the advancement of technology, people's requirements for the waterproof performance of electronic devices are also increasing. Function buttons such as the power button and volume control button of electronic devices are usually installed on the side of the device frame. Because there is a gap between these function buttons and the device frame, if water enters the device through the gap, it can easily damage the components inside the device.

[0003] To improve the waterproof performance of function keys, a sealing structure is installed in the assembly gap between the function keys and the frame of the electronic device. Since the function keys generate friction with the sealing structure when pressed, long-term use may cause the sealing structure to wear out, thereby deteriorating the waterproof performance. Summary of the Invention

[0004] The present application discloses an electronic device to solve the problem in the related art that a sealing structure is easily worn out, resulting in deterioration of the waterproof performance of the electronic device.

[0005] In order to solve the above technical problems, this application is implemented as follows: The embodiment of the present application discloses an electronic device, which includes a frame, a key module and a sealing structure; The frame is used to mount the display module of the electronic device, and includes a frame and a support plate. The frame surrounds the outer periphery of the support plate, and is provided with a first mounting groove, the notch of the first mounting groove faces the display module, and a side surface of the frame is provided with a button mounting groove connected to the first mounting groove; The button module includes a button body and a flexible circuit board. The button body is arranged in the button mounting groove. The main body of the flexible circuit board is arranged in the first mounting groove. The connecting end of the flexible circuit board is connected to the main body via a bent portion. The connecting end is arranged on the side of the support plate facing the display module. The sealing structure at least covers the notch of the first installation slot and the connecting end to form a sealing area at the covered position.

[0006] The technical solution adopted in this application can achieve the following technical effects: The electronic device disclosed in the embodiment of the present application improves the relevant technology, and sets a sealing structure covering the notch of the first mounting groove and the connection end of the flexible circuit board, so that a sealing area can be formed at the position covered by the sealing structure. When the electronic device is in a wading scene, the water immersed in the key mounting groove will be confined in the first mounting groove under the barrier of the sealing structure, and will not flow further into the interior of the electronic device to cause damage to other components, and the key module itself will not be affected because it has a high waterproof level. With the above-mentioned sealing scheme, since there is no need to set an additional seal between the key body and the frame, the problem of deterioration of the waterproof performance of the electronic device due to wear of the seal is avoided, thereby improving the durability of the electronic device.

DETAILED DESCRIPTION

[0009] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the specific embodiments of this application and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0010] The terms "first," "second," etc. in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or sequential sequence. It should be understood that the numerals used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than those illustrated or described herein, and that the objects distinguished by "first," "second," etc. are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally represents that the objects associated with each other are in an "or" relationship.

[0011] The technical solutions disclosed in various embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0012] Please refer to Figures 1 to 18 , an embodiment of the present application discloses an electronic device, which may be a mobile phone, a tablet computer, a laptop computer, a wearable device, a vehicle-mounted device, etc. The embodiment of the present application does not limit the specific type of the electronic device.

[0013] The above-mentioned electronic device may include a frame 110, a key module 120 and a sealing structure 130, wherein the frame 110 is the structural basis of the electronic device, and the frame 110 is used to install the display module 150 of the electronic device. In addition, the frame 110 can also be used to install the circuit board 160, battery, speaker and other components of the electronic device. Specifically, the frame 110 has a first side and a second side opposite to each other along its own thickness direction, and the display module 150 has a display side and an installation side. The installation side of the display module 150 can be connected to the first side of the frame 110 by bonding, snapping, etc., and the circuit board 160, battery, speaker and other components can be connected to the second side of the frame 110. It should be noted that the circuit board 160 can be the main board of the electronic device or the sub-board of the electronic device. It should be explained that the thickness direction can be perpendicular to the display surface of the display module 150.

[0014] The frame 110 includes a frame 111 and a support plate 112. The frame 111 surrounds the outer periphery of the support plate 112. When the display module 150 is assembled with the frame 110, the edge region of the display module 150 can be connected to the frame 111, and the non-edge region of the display module 150 can be connected to the support plate 112. The frame 111 is provided with a first mounting groove 1111, the notch of the first mounting groove 1111 facing the display module 150. The side of the frame 111 is provided with a button mounting groove 1112 that communicates with the first mounting groove 1111. The side of the frame 111 is the surface of the frame 111 facing away from the support plate 112.

[0015] The aforementioned key module 120 can be a power button, volume control button, custom shortcut key, etc. of an electronic device. The key module 120 can include a key body 121 and a flexible circuit board 122. The key body 121 is disposed in the key mounting slot 1112. The flexible circuit board 122 includes a main body 1221, a bent portion 1223, and a connecting end 1222. The main body 1221 is connected to the connecting end 1222 via the bent portion 1223. The main body 1221 of the flexible circuit board 122 is provided with a membrane switch, a pot switch, etc., and the connecting end 1222 can be provided with a conductive contact 1224, a plug connector, and other structures. The main body 1221 of the flexible circuit board 122 is arranged in the first mounting groove 1111 and is in contact with the button body 121 arranged in the button mounting groove 1112. The button body 121 can be a mechanical button, a capacitive button, etc. Taking a mechanical button as an example, when the user presses the button body 121, the button body 121 can move into the button mounting groove 1112 and apply a certain pressure to the membrane switch, pot switch and other switching elements arranged on the main body 1221 to trigger the corresponding operation instructions.

[0016] The main body 1221 of the flexible circuit board 122 is connected to the connecting end 1222 via a bent portion 1223. The bent portion 1223 extends from the notch of the first mounting slot 1111. The connecting end 1222 is disposed on the side of the support plate 112 facing the display module 150. The connecting end 1222 is used to electrically connect to the circuit board 160 of the electronic device, thereby transmitting the aforementioned operating instructions to the circuit board 160, which then controls the electronic device to perform the corresponding operation. It should be noted that the button body 121 can be mounted in the button mounting slot 1112 via a bracket, which can be fixed within the button mounting slot 1112. When the button body 121 is pressed, the button body 121, the bracket, and the frame 111 can move relative to each other. After the pressure applied to the button body 121 is removed, the button body 121 can return to its previous position.

[0017] Since the button mounting groove 1112 and the first mounting groove 1111 are connected to each other, the end of the button body 121 needs to extend from the bottom of the button mounting groove 1112 into the first mounting groove 1111 and contact the main body 1221 of the flexible circuit board 122. Therefore, an assembly gap needs to be reserved between the button body 121 and the button mounting groove 1112 for the button body 121 to move relative to the button mounting groove 1112 (frame 111). When the electronic device is in a wading scene, external water will enter the first mounting groove 1111 from the assembly gap between the button mounting groove 1112 and the button body 121, and then flow out from the notch of the first mounting groove 1111, and further flow to the electrical components in the frame 110, such as the display module 150, the circuit board 160, etc., which may easily cause damage to these electrical components.

[0018] To address the above issues, a sealing structure 130 can be provided on the first side of the frame 110. The sealing structure 130 covers at least the notch of the first mounting slot 1111 and the connection end 1222 of the flexible circuit board 122. The sealing structure 130 can be made of a sealant, a silicone sealant, or the like. The sealing structure 130 is sealedly connected to the frame 111 and the support plate 112, respectively, thereby forming a sealed area at the covered locations. When the notch of the first mounting slot 1111 and the connection end 1222 of the flexible circuit board 122 are sealed by the sealing structure 130, water can be prevented from flowing further from the notch of the first mounting slot 1111 into the interior of the electronic device.

[0019] It should be noted that, since the key module 120 itself has a high waterproof rating, even if water enters the first mounting groove 1111, it will not affect the normal operation of the key module 120. In other words, the first mounting groove 1111 is actually a wading area. The notch of the above-mentioned first mounting groove 1111 faces the side of the display module 150. This is because the first side of the frame 110 is relatively flat, which is convenient for setting the sealing structure 130, while the second side of the frame 110 needs to be equipped with batteries and speaker components, which has a more complex structure and is not conducive to setting the sealing structure 130. Of course, when the second side of the frame 110 meets the installation conditions required for the sealing structure 130, the first mounting groove 1111 can also be set on the second side of the frame 110.

[0020] As can be seen from the above, the electronic device disclosed in the embodiment of the present application improves the relevant technology. When the electronic device is in a wading scene, the water entering through the notch of the first mounting groove 1111 will be confined within the first mounting groove 1111 under the obstruction of the sealing structure 130, and will not flow further into the interior of the electronic device to cause damage to other components, while the key module 120 itself has a high waterproof level and will not be affected. With the above-mentioned sealing solution, since no additional seal is required between the key body 121 and the frame 111, the problem of deterioration of the waterproof performance of the electronic device due to wear of the seal is avoided, thereby improving the durability of the electronic device. Moreover, since the seal between the key body 121 and the frame 111 is eliminated, it is also beneficial to free up the internal space of the frame 111 to improve the lightness and thinness of the electronic device. In addition, since no additional seal is required between the key body 121 and the frame 111, the triggering feel of the key body 121 can be improved to a certain extent, which is beneficial to improving the user experience.

[0021] like Figures 1 to 9The support plate 112 is provided with a second mounting groove 1121, which can be used to mount the connection end 1222 of the flexible circuit board 122. The bottom wall of the second mounting groove 1121 (i.e., the bottom wall of the second mounting groove 1121 opposite its notch) has a through hole 1122 for exposing a partial area of ​​the connection end 1222. The notch of the second mounting groove 1121 faces the display module 150. The second mounting groove 1121 communicates with the first mounting groove 1111 via a first groove 1123. The bent portion 1223 of the flexible circuit board 122 connects the main body 1221 and the connection end 1222 via the first groove 1123. In some embodiments, to ensure smooth installation of the sealing structure 130, the notch of the first mounting groove 1111 is flush with the notch of the second mounting groove 1121.

[0022] The circuit board 160 can be positioned on the side of the support plate 112 facing away from the display module 150. The aforementioned through-hole 1122 can also be used to expose a partial area of ​​the circuit board 160. The connection end 1222 of the flexible circuit board 122 can be electrically connected to the circuit board 160 through the through-hole 1122. To facilitate the placement of the flexible circuit board 122, the bent portion 1223 of the flexible circuit board 122 needs to extend out of the first mounting slot 1111 through the first groove 1123. However, the first groove 1123 also serves as a water channel. Water in the first mounting slot 1111 may flow along the first groove 1123 into the second mounting slot 1121, and may even continue to flow into the through-hole 1122 on the bottom wall of the second mounting slot 1121, which can easily damage the circuit board 160.

[0023] Based on the above problem, when installing the connection end 1222 of the flexible circuit board 122, the connection end 1222 can be covered on the through hole 1122, and the connection end 1222 can be sealed to the outer periphery of the through hole 1122. The above-mentioned sealing structure 130 can then be used to seal the notch of the first installation groove 1111 and the connection end 1222 of the flexible circuit board 122. Even if water flows along the first groove 1123 to the vicinity of the connection end 1222, it will be confined within the sealing area formed by the sealing structure 130, thereby further improving the waterproof performance of the electronic device.

[0024] For example, a silicone sealing pad may be provided between the connection end 1222 and the periphery of the through hole 1122 , a waterproof double-sided tape may be provided between the connection end 1222 and the periphery of the through hole 1122 , or glue injection sealing may be performed between the connection end 1222 and the periphery of the through hole 1122 .

[0025] In an optional embodiment of the present application, Figures 1 to 3As shown, the sealing structure 130 may include a first sealing member 131, which is bonded to the frame 111 and the support plate 112 respectively, and the first sealing member 131 covers at least the notch of the first mounting groove 1111 and the notch of the second mounting groove 1121, thereby forming a sealing area at the notch of the first mounting groove 1111 and the notch of the second mounting groove 1121. The first sealing member 131 may be a waterproof double-sided tape, or the sealing glue may be applied to the frame 111 and the support plate 112, and the first sealing member 131 may be formed after the sealing glue is cured. Under the sealing action of the first sealing member 131, a sealing area is formed above the notch of the first mounting groove 1111 and the notch of the second mounting groove 1121, thereby confining water within the first mounting groove 1111 and the second mounting groove 1121, preventing water from further flowing into the interior of the electronic device and damaging the electrical components.

[0026] like Figure 3 The first seal 131 may include a first sub-seal 1311 and a second sub-seal 1312 connected to each other. The first sub-seal 1311 covers the notch of the first mounting groove 1111 and the notch of the second mounting groove 1121. To prevent water from entering the interior of the electronic device through the edge of the display module 150, a second sub-seal 1312 may be disposed between the display module 150 and the frame 110 during assembly. The second sub-seal 1312 extends along the circumference of the frame 111 and serves to bond the display module 150 to the frame 110 (the frame 111 and the support plate 112). The second sub-seal 1312 is located near the edge of the display module 150. In other words, the first sealant 131 can not only seal the notch of the first installation groove 1111 and the notch of the second installation groove 1121, but can also be reused for sealing and bonding the display module 150 and the frame 110, thereby bonding and fixing the display module 150 to the frame 110, achieving a dual-purpose effect.

[0027] In an optional embodiment of the present application, Figures 4 to 13As shown, the sealing structure 130 may further include a cover plate 132 and a second sealing member 133. The second sealing member 133 is disposed at the edge of the surface of the cover plate 132 facing the first mounting groove 1111. The second sealing member 133 may be waterproof double-sided tape, or the second sealing member 133 may be formed by applying sealing glue to the edge of the surface of the cover plate 132. The cover plate 132 is bonded to the frame 111 and the support plate 112 via the second sealing member 133. The cover plate 132 covers the notches of the first mounting groove 1111 and the second mounting groove 1121, and the second sealing member 133 surrounds the notches of the first mounting groove 1111 and the second mounting groove 1121, thereby forming a sealed area at the notches of the first mounting groove 1111 and the second mounting groove 1121. Under the sealing effect of the cover plate 132, water can be confined within the first mounting groove 1111 and the second mounting groove 1121, preventing water from flowing further into the interior of the electronic device and damaging the electrical components.

[0028] like Figures 8 to 11 As shown, to prevent the cover plate 132 from excessively protruding beyond the frame 111 and support plate 112 and thereby interfering with components such as the display module 150, a first recessed groove 140 can be defined in the frame 110. The first recessed groove 140 circumferentially surrounds the notch of the first mounting groove 1111 and the notch of the second mounting groove 1121. The cover plate 132 covers the first recessed groove 140 and is bonded to the bottom wall of the first recessed groove 140 (i.e., the bottom wall of the first recessed groove 140) via a second sealing member 133. Furthermore, the sidewalls of the first recessed groove 140 can also limit the side edges of the cover plate 132, preventing the cover plate 132 from shifting relative to the frame 110 and affecting the sealing effect.

[0029] like Figures 5 to 13 As shown, to improve the assembly accuracy of the cover plate 132, a first positioning portion 1321 can be provided on the first end of the cover plate 132, and a second positioning portion 141 can be provided on the sidewall of the first recessed groove 140. When the cover plate 132 is covered in the first recessed groove 140, the first positioning portion 1321 and the second positioning portion 141 engage with each other, thereby accurately controlling the installation position of the cover plate 132. The first positioning portion 1321 can be a protrusion, and the second positioning portion 141 can be a groove, or the first positioning portion 1321 can be a groove, and the second positioning portion 141 can be a protrusion.

[0030] Considering that the cover plate 132 is bonded to the bottom wall of the first sink 140 only through the second seal 133, there may be a risk of the cover plate 132 falling off. Therefore, a first connecting hole 1322 can be provided at the second end of the cover plate 132, and a second connecting hole 142 can be provided at the bottom wall of the first sink 140. Fasteners are respectively passed through the first connecting hole 1322 and the second connecting hole 142 to reinforce the cover plate 132 and the first sink 140. The fasteners can be structures such as bolts and snaps. For example, the second connecting hole 142 can be a threaded hole, which passes through the first connecting hole 1322 and is threadedly connected to the second connecting hole 142. In particular, in some embodiments, the second end of the cover plate 132 is disposed in the circumference of the second mounting groove 1121, and the first end of the cover plate 132 is disposed in the circumference of the first mounting groove 1111.

[0031] To prevent water from flowing onto the circuit board 160 through the through-hole 1122, the connection end 1222 of the flexible circuit board 122 is sealed to the periphery of the through-hole 1122. A silicone sealing gasket may be provided between the connection end 1222 and the periphery of the through-hole 1122 to achieve sealing. In an optional embodiment of the present application, the key module 120 may further include a third sealing member 123. The third sealing member 123 may be a waterproof double-sided tape. Alternatively, the sealing glue may be applied to the edge area of ​​the surface of the connection end 1222 facing away from the display module 150 to form the aforementioned third sealing member 123. The connection end 1222 of the flexible circuit board 122 may be bonded to the support plate 112 via the third sealing member 123. In this case, the third sealing member 123 is disposed around the circumference of the through-hole 1122, thereby forming a sealed area around the through-hole 1122 and preventing water from flowing onto the circuit board 160 through the through-hole 1122.

[0032] To enhance the structural strength of the connection end 1222 of the flexible printed circuit board 122 and ensure a stable, sealed connection with the circumference of the through-hole 1122, the key module 120 may further include a reinforcing plate 124. The reinforcing plate 124 may be made of metal and attached to the surface of the connection end 1222 facing away from the through-hole 1122. The specific attachment method may be adhesive bonding, snap-fitting, or other methods. To prevent the reinforcing plate 124 from excessively protruding from the support plate 112, when the connection end 1222 is positioned within the second mounting groove 1121, at least a portion of the reinforcing plate 124 may extend into the second mounting groove 1121. Furthermore, the sidewalls of the second mounting groove 1121 may also limit the side edges of the reinforcing plate 124 to prevent positional displacement between the reinforcing plate 124 and the support plate 112, which could affect the sealing effect and the stability of the electrical connection. In some embodiments, after installation, the thickness of the reinforcing plate 124 may be less than or equal to the depth of the second mounting groove 1121.

[0033] like Figure 1As shown, the electronic device may further include a circuit board 160, which is provided on a side of the support plate 112 facing away from the display module 150 (i.e., the second side of the frame 110), and the connection end 1222 of the flexible circuit board 122 is used to be electrically connected to the circuit board 160. The specific connection method may be conductive bonding, abutment, plugging, etc. In an optional embodiment of the present application, as shown in FIG. Figure 1 As shown, the circuit board 160 of the electronic device can be provided with an elastic electrical connector 161, such as an elastic conductive sheet, an elastic metal clip, etc., and the elastic electrical connector 161 can be soldered to the circuit board 160. The connection end 1222 has a conductive contact 1224. When the connection end 1222 is covered in the through hole 1122, the conductive contact 1224 can elastically contact the elastic electrical connector 161 to electrically connect the flexible circuit board 122 and the circuit board 160. This can improve the reliability of the connection between the connection end 1222 and the circuit board 160, and the electrical connection between the key flexible circuit board 122 and the circuit board 160 can achieve signal transmission.

[0034] Circuit board 160 employs the aforementioned design of elastic electrical connector 161. This elastic connector 161 exerts an elastic force on connecting end 1222 and reinforcing plate 124, which is directed away from circuit board 160. This can easily cause circumferential separation between connecting end 1222 and through-hole 1122, thereby affecting the sealing effect. To address this issue, an elastic snap 1124 can be provided on the sidewall of second mounting slot 1121. When connecting end 1222 and reinforcing plate 124 are positioned over through-hole 1122, the edge of reinforcing plate 124 can engage with the elastic snap 1124, thereby pressing connecting end 1222 and reinforcing plate 124 against the bottom wall of second mounting slot 1121 and counteracting the elastic force exerted by elastic connector 161 on connecting end 1222 and reinforcing plate 124. This can also further enhance the reliability of the electrical connection between connecting end 1222 and circuit board 160. In some embodiments, the elastic electrical connector 161 is a conductive foam, a conductive spring, a conductive adhesive, etc., which is not specifically limited in this application.

[0035] like Figures 15 to 18 As shown, the main body 1221 of the flexible circuit board 122 further includes a trigger end 1225. The trigger end 1225 can be a pot switch, a membrane switch, or the like. The trigger end 1225 is disposed on the flexible circuit board 122 and corresponds to the key mounting slot 1112. To ensure that the key body 121 can stably cooperate with the trigger end 1225 to trigger the corresponding operation command, the key module 120 further includes a mounting bracket 125. The mounting bracket 125 is disposed within the first mounting slot 1111 and is connected to the flexible circuit board 122. The mounting bracket 125 can be connected to the slot wall of the first mounting slot 1111 by bonding, snapping, or other means.

[0036] In addition, the key module 120 may also include a strike post disposed at the end of the key body 121. The bottom wall of the key mounting groove 1112 has a strike post through-hole. The strike post extends through the strike post through-hole into the first mounting groove 1111 and presses the trigger end 1225. In the related art, to ensure waterproof performance, a sealing ring is provided between the strike post and the strike post through-hole. However, due to frequent friction between the strike post and the strike post through-hole, the sealing ring can easily wear out and fail. In the present application, by moving the sealing structure 130 to above the notch of the first mounting groove 1111 and the notch of the second mounting groove 1121, it is not affected by the pressing activity of the key module 120, thus avoiding the problem of deterioration of the electronic device's waterproof performance due to seal ring wear. The sealing ring structure is discarded, and the durability of the electronic device is improved. The present application improves the waterproof surface from the strike post to the interface between the display module 150 and the frame 110, saving seal rings while achieving a highly efficient waterproof structure.
