Technical Field

[0001] This application relates to the field of waterproofing technology, specifically to an electronic device. Background Technology

[0002] During the production and assembly process of electronic devices, the casing needs to have openings to ensure the realization of corresponding functions, such as sound generation, wire passage, and light transmission. Since moisture can cause short circuits and corrode electronic components, electronic devices typically need to have good waterproof performance.

[0003] Compared to other parts of the casing, moisture can more easily enter the interior of electronic devices through openings, damaging the internal circuitry. Therefore, improving the waterproof performance of electronic devices is a pressing issue that needs to be addressed. Utility Model Content

[0004] In view of the above problems, embodiments of this application provide an electronic device that can ensure that moisture does not easily enter the interior of the casing, thereby improving the waterproof performance of the electronic device.

[0005] This application provides an electronic device, including: a housing, with a sound outlet at the bottom of the housing and insertion portions on both sides of the sound outlet; a speaker, inserted into the insertion portions, with the sound-emitting portion of the speaker facing the sound outlet; and a first sealing ring, disposed between the speaker and the housing, for sealing the gap between the speaker and the housing.

[0006] In one alternative embodiment, the connector includes a first slot and a second slot disposed opposite to each other, and stepped structures are provided on opposite sides of the speaker, the stepped structures being inserted into the first slot and the second slot respectively.

[0007] In one alternative embodiment, the loudspeaker has a fixing groove on the outer periphery of the sound-emitting part, and a first sealing ring is accommodated in the fixing groove and at least partially protrudes from the opening of the fixing groove; the fixing groove is used to limit the first sealing ring during the insertion of the stepped structure into the first slot and the second slot, and after the stepped structure is inserted into place, the first sealing ring is clamped between the inner wall of the fixing groove and the inner wall of the housing.

[0008] In one alternative embodiment, the first sealing ring has multiple raised rings on the side facing the housing, each raised ring abutting against the inner wall of the housing.

[0009] In one alternative embodiment, the housing has a wire-passing hole for the wire harness to pass through, and the electronic device also includes a pressure plate and a second sealing ring. The pressure plate is fixed to the wire-passing hole of the housing and is used for the wire harness to pass through. The second sealing ring is clamped between the pressure plate and the housing and is used to seal the gap between the pressure plate and the housing.

[0010] In one alternative approach, a through hole is provided on the pressure plate, and a hollow soft rubber plug is sealed and filled inside the through hole. The wire harness passes through the soft rubber plug, and the soft rubber plug is sealed and fitted around the outer periphery of the wire harness.

[0011] In one alternative embodiment, the housing has a connecting hole on the inner wall around the wire hole, and the pressure plate has a corresponding fixing hole. The connecting hole is used for fasteners to pass through and connect with the fixing hole to fix the pressure plate to the housing; the second sealing ring is located on the outer periphery of the connecting hole.

[0012] In one alternative approach, the housing has multiple limiting holes on the inner wall around the wire passage hole, and the pressure plate is provided with multiple limiting pins accordingly. The limiting pins are inserted into the limiting holes so that the fixing hole is aligned with the connecting hole.

[0013] In one alternative embodiment, the housing has a shooting window, and the housing has a first stepped groove on the inner wall of the shooting window edge; the electronic device also includes a light-transmitting component, which has an annular convex wall; the light-transmitting component covers the outside of the shooting window, the annular convex wall extends into the shooting window and protrudes from the inner wall of the housing, and the space between the outer periphery of the annular convex wall and the inner wall of the first stepped groove is filled with sealant.

[0014] In one alternative embodiment, the light-transmitting component includes a mounting plate and a light-transmitting element, with an annular convex wall disposed on the mounting plate. The mounting plate has a light-transmitting hole on the inner circumference of the annular convex wall, and the light-transmitting element is sealed in the light-transmitting hole.

[0015] In one alternative embodiment, a supplementary light is also provided inside the housing, and a light-emitting window is provided on the housing opposite to the supplementary light. A second stepped groove is provided on the inner wall of the housing at the edge of the light-emitting window. The electronic device also includes a lens, one end of which protrudes outward to form a locking part. The lens is inserted into the light-emitting window, and the locking part abuts against the bottom wall of the second stepped groove. Sealant is filled between the outer periphery of the locking part and the inner wall of the second stepped groove.

[0016] In one alternative embodiment, the housing includes a first housing and a second housing, the first housing being snap-fitted to the second housing, and a third sealing ring being held at the junction of the first housing and the second housing.

[0017] In the electronic device provided in this application embodiment, by opening the sound outlet at the bottom of the housing, water is prevented from entering the interior through the sound outlet under the action of gravity, thus achieving a preliminary waterproofing effect. Furthermore, the speaker is assembled inside the housing using a plug-in method. With the sound-emitting part of the speaker facing the sound outlet, a first sealing ring reliably seals the assembly gap between the speaker and the housing. This ensures that when moisture enters from the sound outlet, the first sealing ring can isolate the moisture between the housing and the speaker, preventing moisture from penetrating into the housing and damaging the internal circuit components, thereby improving the waterproof performance of the electronic device.

[0041] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0042] To address the sealing of the sound outlet in electronic devices, this application employs an inverted speaker installation method. The sound outlet is positioned at the bottom of the electronic device's housing, with the speaker's sound-producing part facing downwards towards the outlet, minimizing water ingress through the outlet. For ease of assembly, a plug-in connection is used. Considering the speaker's inherent water resistance, and that water entering through the outlet could easily damage other electronic components if it bypasses the speaker and enters the housing, a sealing ring is sandwiched between the speaker's surface and the inner wall of the housing located around the outlet. If water enters the outlet, it is contained within the sealing ring by the ring, preventing it from penetrating the housing and thus ensuring the electronic device's waterproof performance.

[0043] This application provides an electronic device; please refer to the specific details. Figures 1 to 3 , Figure 1 The overall structure of the electronic device is shown. Figure 2 and Figure 3 The assembly structure and the exploded structure at the speaker inside the housing are shown respectively. It should be noted that the electronic device in the figure is a camera as an example, which does not constitute a limitation on the specific type of electronic device. For example, in some other embodiments, the electronic device may also be an electronic doorbell with a speaker, an electronic toy, etc.

[0044] like Figures 1 to 3 As shown, the electronic device 100 includes: a housing 110, a speaker 120, and a first sealing ring 130. The housing 110 has a sound outlet 111 at its bottom, and insertion portions 112 are provided on both sides of the sound outlet 111. The speaker 120 is inserted into the insertion portions 112. Please refer to further details. Figure 4 The bottom structure of the speaker 120 shown is such that after the speaker 120 is inserted into the connector 112, the sound-emitting part 121 of the speaker 120 faces the sound outlet 111 to ensure that the sound output by the sound-emitting part 121 can be transmitted to the outside through the sound outlet 111.

[0045] The first sealing ring 130 is disposed between the speaker 120 and the housing 110 to seal the gap between the speaker 120 and the housing 110. Specifically, as shown... Figure 4 As shown, the first sealing ring 130 can be clamped by the speaker 120 and the inner wall of the housing 110 on the outer periphery of the sound-emitting part 121 and the sound outlet 111 to ensure that the moisture entering from the sound outlet 111 will be isolated from the inner periphery of the first sealing ring 130 and will not further enter the interior of the housing 110, thereby providing reliable waterproof protection for the circuit inside the housing 110.

[0046] At the top of speaker 120 Figure 2 When other components are installed as shown, if the speaker 120 is installed using a vertical plug-in method, disassembling, maintaining, or replacing the speaker 120 requires first removing the other parts at the top before the speaker 120 can be properly installed or removed. This process is cumbersome, time-consuming, and labor-intensive. Therefore, to facilitate easy installation and removal of the speaker 120, the plug-in part 112 can be designed as follows: Figure 3The diagram shows a first slot 1121 and a second slot 1122 arranged opposite to each other. Stepped structures 123 are provided on opposite sides of the speaker 120. The speaker 120 slides parallel to the bottom wall of the housing 110 and is inserted into the first slot 1121 and the second slot 1122 respectively through the stepped structures 123 on both sides. This insertion assembly method ensures that other parts of the top of the speaker 120 will not interfere with the assembly and disassembly of the speaker 120, thus achieving convenient and efficient assembly and disassembly of the speaker 120. Furthermore, in the horizontal insertion assembly method, the first slot 1121 and the second slot 1122 can limit the stepped structure 123 in the vertical direction, reliably pressing the first sealing ring 130 between the speaker 120 and the inner wall of the housing 110, thereby ensuring that the first sealing ring 130 can provide a reliable sealing effect.

[0047] Furthermore, in order to improve the stability of the speaker 120 assembly, such as Figure 3 As shown, abutment blocks 1123 can be provided in the first slot 1121 and the second slot 1122. Threaded holes are provided on the abutment blocks 1123. Abutment pieces 1231 can be provided on both sides of the stepped structure 123. Through holes are provided on the abutment pieces 1231. During the insertion of the speaker 120 into the first slot 1121 and the second slot 1122, after the abutment pieces 1231 contact the abutment blocks 1123, it indicates that the speaker has been inserted into place. Then, screws can be passed through the through holes on the abutment pieces 1231 and screwed into the threaded holes on the abutment blocks 1123 to reliably fix the speaker 120 in the first slot 1121 and the second slot 1122, ensuring the structural stability of the speaker 120 after assembly.

[0048] To ensure the accuracy of the position of the first sealing ring 130 after assembly, such as Figure 4 As shown, a fixing groove 122 can be formed on the outer periphery of the sound-emitting part 121 at the bottom of the speaker 120. During assembly, the first sealing ring 130 can be accommodated in the fixing groove 122. When the speaker 120 is inserted into the first slot 1121 and the second slot 1122 together with the stepped structure 123 of the speaker 120, the first sealing ring 130 is not easy to shift due to force under the limiting effect of the fixing groove 122. After the speaker 120 is inserted into place, the first sealing ring 130 can be effectively clamped between the inner wall of the fixing groove 122 and the inner wall of the housing 110 to achieve a stable and reliable waterproof effect.

[0049] In addition, such as Figure 4 As shown, the first sealing ring 130 can be provided with multiple protrusions 131 on the side facing the housing 110. Each protrusion 131 abuts against the inner wall of the housing 110, thereby forming multiple waterproof barriers to achieve better waterproof effect.

[0050] In summary, in the electronic device 100 provided in this application embodiment, by opening the sound outlet 111 at the bottom of the housing 110, water is prevented from entering the interior through the sound outlet 111 under the action of gravity, thus achieving a preliminary waterproofing effect. Furthermore, the speaker 120 is assembled inside the housing 110 by a plug-in connection. While the sound-emitting part 121 of the speaker 120 faces the sound outlet 111, the first sealing ring 130 reliably seals the assembly gap between the speaker 120 and the housing 110. This ensures that when moisture enters from the sound outlet 111, the first sealing ring 130 can isolate the moisture between the housing 110 and the speaker 120, preventing moisture from penetrating into the interior of the housing 110 and damaging the internal circuit components, thereby improving the waterproof performance of the electronic device 100.

[0051] In addition to the waterproof design at the sound outlet 111, this application also includes a waterproof design at the wiring locations on the housing 110. Please refer to [link / reference needed] for details. Figures 5 to 7 , Figure 5 The structure of the electronic device in the state of an overall explosion is shown. Figure 6 and Figure 7 The structure at the wire pass hole is shown from two perspectives under an explosion condition. The housing 110 has a wire pass hole 113 for the wire harness 140 to pass through. The electronic device 100 also includes a pressure plate 150 and a second sealing ring 160. The pressure plate 150 is fixed to the wire pass hole 113 of the housing 110, and the pressure plate 150 allows the wire harness 140 to pass through. The second sealing ring 160 is clamped between the pressure plate 150 and the housing 110, and the second sealing ring 160 is used to seal the gap between the pressure plate 150 and the housing 110.

[0052] In this embodiment, a second sealing ring 160 is first installed on the inner wall of the outer periphery of the wire passage hole 113 to waterproof the wire passage hole 113. To ensure better sealing effect, a pressure plate 150 is used to press the second sealing ring 160 tightly against the inner wall of the housing 110, ensuring an interference fit at the second sealing ring 160. The wire harness 140 enters the housing 110 through the pressure plate 150 and connects to the corresponding circuit structure to achieve power or signal transmission. Simultaneously, the pressure plate 150 tightly fits onto the wire harness 140 to seal its outer periphery, preventing moisture from passing through the gap between the pressure plate 150 and the wire harness 140. Based on the sealing between the inner wall of the outer periphery of the wire passage hole 113 and the pressure plate 150 by the second sealing ring 160, and the sealing of the outer periphery of the wire harness 140 by the pressure plate 150, the interior of the housing 110 and the wire passage hole 113 are effectively isolated, thereby improving the waterproof performance of the wire passage hole 113.

[0053] Similar to the method of fixing the first sealing ring 130 to the speaker 120 mentioned above, a groove can also be opened on the pressure plate 150. By partially accommodating the second sealing ring 160 in the groove of the pressure plate 150, the second sealing ring 160 is limited, ensuring that the second sealing ring 160 is not easily displaced after assembly, thus preventing sealing failure.

[0054] Regarding the sealing of the outer periphery of the pressure plate 150 and the wire harness 140, a simple method of applying sealant can be used. However, considering that applying sealant would prevent the pressure plate 150 from being disassembled and separated from the wire harness 140, causing inconvenience for subsequent disassembly and maintenance, this application also proposes an alternative implementation method. Please refer to the following for details. Figure 6 and Figure 7 The pressure plate 150 has a through hole 151, and a hollow soft rubber plug 152 is sealed and filled inside the through hole 151. The wire harness 140 passes through the soft rubber plug 152, and the soft rubber plug 152 is sealed and fitted around the outer periphery of the wire harness 140.

[0055] Specifically, the soft rubber plug 152 can be filled into the through hole 151 of the pressure plate 150 by an interference fit. That is, the soft rubber plug 152 is compressed to insert into the through hole 151. After insertion, the soft rubber plug 152 tends to recover its deformation and fit tightly against the inner wall of the through hole 151, thereby achieving a seal between the outer periphery of the soft rubber plug 152 and the inner wall of the through hole 151. Similarly, the soft rubber plug 152 and the outer periphery of the wire harness 140 can also be sealed by mutual compression to form an interference fit.

[0056] By using a soft rubber plug 152 inside the pressure plate 150 for the wire harness 140 to pass through, and by sealing the outer periphery of the wire harness 140 with the soft rubber plug 152, not only can a good sealing effect be achieved, but also all components are detachable, thus providing convenience for the later disassembly and maintenance of the electronic device 100.

[0057] In order for the pressure plate 150 to better press the second sealing ring 160, such as Figure 6 and Figure 7 As shown, the housing 110 has a connecting hole 114 around the wire hole 113, and the pressure plate 150 has a corresponding fixing hole 153. The connecting hole 114 is used for fasteners 154 (such as screws, pins, etc.) to pass through and connect with the fixing hole 153 to fix the pressure plate 150 to the housing 110. At the same time, in order to prevent moisture from entering the interior of the housing 110 through the connecting hole 114, a second sealing ring 160 is provided on the outer periphery of the connecting hole 114, so that even if water enters through the connecting hole 114, the second sealing ring 160 will isolate it between the pressure plate 150 and the inner wall of the housing 110.

[0058] Both the connecting hole 114 and the fixing hole 153 can be used as follows Figure 6 and Figure 7 Multiple sealing rings are evenly arranged around the circumference of the wire hole 113, so that the pressure plate 150 can effectively press the second sealing ring 160 at each position after assembly, ensuring the sealing performance of the second sealing ring 160.

[0059] Furthermore, to facilitate the alignment of the fixing hole 153 and the connecting hole 114, and to better enable assembly operations using the fastener 154, such as... Figure 6 and Figure 7 As shown, the housing 110 has multiple limiting holes 115 on its inner wall around the wire hole 113, and the pressure plate 150 has multiple limiting pins 155 correspondingly. After the limiting pins 155 are inserted into the limiting holes 115 one by one, the pressure plate 150 cannot rotate, and the fixing hole 153 and the connecting hole 114 are aligned with each other, so that the fastener 154 can be easily connected to the fixing hole 153 after passing through the connecting hole 114.

[0060] like Figure 8 As shown, the electronic device 100 can be a camera 101, or other devices with shooting capabilities. A lens 170 can be housed within its casing 110. A shooting window 116 can be opened on the casing 110 opposite to the lens 170. Regarding the sealing of the shooting window 116, please further consider... Figure 9 and Figure 10 The figure shows the exploded structure at the shooting window 116 from both inner and outer perspectives. The housing 110 has a first stepped groove 117 on the inner wall of the edge of the shooting window 116. The electronic device 100 also includes a light-transmitting component 180, which has an annular protrusion 181. The light-transmitting component 180 covers the outer side of the shooting window 116. After assembly, as shown... Figure 11 As shown, the annular convex wall 181 extends into the imaging window 116 and protrudes from the inner wall of the housing 110. The area between the outer periphery of the annular convex wall 181 and the inner wall of the first stepped groove 117 is filled with sealant (the area where the sealant is located is...). Figure 11 (The area indicated by the medium shaded line).

[0061] It should be noted that, in Figure 11 In the specific embodiment shown, the electronic device 100 is a binocular camera, and its housing 110 has two shooting windows 116. The two shooting windows 116 are sealed in the same way. Figure 11 In this design, only one of the shooting windows 116 uses a shaded line to show the area filled with sealant. The other shooting window 116, for ease of structural visualization, is not shaded. In actual production and assembly, both shooting windows 116 need to be sealed with sealant. Of course, this binocular camera is only one example; in other embodiments, only one shooting window 116 may be used.

[0062] In this embodiment, a first stepped groove 117 is first opened on the edge of the inner wall of the shooting window 116, and an annular convex wall 181 is provided on the light-transmitting component 180. After the light-transmitting component 180 is covered on the shooting window 116 from the outside, the annular convex wall 181 extends into the shooting window 116 and protrudes out of the inner wall of the housing 110, so that the outer periphery of the annular convex wall 181 and the inner wall of the first stepped groove 117 form a complete groove-shaped space. This groove-shaped space can keep the injected sealant inside, ensuring that the position of the sealant is controllable. After the sealant dries, it can not only effectively seal the gap between the annular convex wall 181 and the housing 110, but also bond and fix the light-transmitting component 180 to the housing 110, thereby simultaneously achieving the sealing of the shooting window 116 and the assembly of the light-transmitting component 180 on the housing 110.

[0063] like Figure 9 As shown, the light-transmitting component 180 may include a mounting plate 182 and a light-transmitting element 183. The mounting plate 182 may be made of transparent or opaque plastic for decorative purposes, while the light-transmitting element 183 may be made of transparent glass or similar materials to protect the internal lens 170 while ensuring that light can pass through and enter the lens 170. An annular convex wall 181 is disposed on the mounting plate 182, and a light-transmitting hole 1821 is formed on the inner circumference of the mounting plate 182. The light-transmitting element 183 is sealed within the light-transmitting hole 1821. Specifically, a step portion 1822 may be provided on the inner circumference of the light-transmitting hole 1821. After the light-transmitting element 183 is inserted into the light-transmitting hole 1821 from the inside and abuts against the step portion 1822, a seal is achieved between the light-transmitting element 183 and the mounting plate 182 by applying sealant between the light-transmitting element 183, the step portion 1822, and the inner wall of the light-transmitting hole 1821.

[0064] To ensure image quality even in low-light conditions, such as Figures 8 to 10 As shown, a supplementary light 190 is also provided inside the housing 110. A light-emitting window 118 is provided on the housing 110 opposite to the supplementary light 190. A second stepped groove 119 is provided on the inner wall of the edge of the light-emitting window 118. The electronic device 100 also includes a lens 191. One end of the lens 191 protrudes outward to form a locking part 1911. The lens 191 is inserted into the light-emitting window 118, and the locking part 1911 abuts against the bottom wall of the second stepped groove 119. The space between the outer periphery of the locking part 1911 and the inner wall of the second stepped groove 119 is filled with sealant.

[0065] For ease of assembly, Figure 11 In the specific embodiment shown, the second step groove 119 and the first step groove 117 are interconnected to form the same step groove, therefore in Figure 11In the diagram, the shaded lines represent the sealant filling the space between the annular convex wall 181 and the inner wall of the first stepped groove 117, as well as between the snap-fit ​​portion 1911 and the inner wall of the second stepped groove 119. This arrangement allows the light-transmitting component 180 and the lens 191 to be fixed simultaneously with a single application of sealant during assembly, after the light-transmitting component 180 and the lens 191 are positioned, and the assembly gaps are sealed, thereby improving assembly efficiency.

[0066] In addition, such as Figure 9 As shown, in the embodiment where the light-transmitting component 180 includes a mounting plate 182 and a light-transmitting element 183, the mounting plate 182 can simultaneously cover the outer periphery of the lens 191 to provide a certain decorative and protective effect for the lens 191.

[0067] Please refer to it again. Figure 5 In some embodiments, the housing 110 may include a first housing 1101 and a second housing 1102, the first housing 1101 and the second housing 1102 being fastened together, and a third sealing ring 1103 being clamped at the joint between the first housing 1101 and the second housing 1102 to seal the assembly gap between the first housing 1101 and the second housing 1102.

[0068] In summary, in the various embodiments provided in this application, corresponding sealing designs have been made for the sound outlet 111, the wire hole 113, the shooting window 116, the light outlet window 118, and the assembly gap between the first housing 1101 and the second housing 1102, so that the electronic device 100 (which may be a camera 101 or other types of electronic devices) has good waterproof performance as a whole, ensuring its stability and reliability.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application. In particular, as long as there is no structural conflict, the various technical features mentioned in the various embodiments can be combined in any way.
