[0046] The following embodiments of the technical solution of the present application will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application and are therefore only examples and are not intended to limit the scope of protection of the present application.

[0047] The electronic device described in the embodiments of this application takes a battery-powered camera as an example. Because such cameras require no power cords, they are relatively simple to install and are widely popular in the market. At the same time, to achieve wireless transmission of images, videos, and other information, the camera requires an antenna for signal transmission and reception. When an external antenna is used, the antenna's size is no longer limited by the camera's internal space, and its operation is largely unaffected by interference from the camera's internal circuitry. This significantly improves the antenna's signal strength, extends transmission distance, and accelerates transmission speed. However, existing external antennas have poor waterproofing at the connection between the camera and the main body, resulting in poor stability and reliability of the internal circuitry.

[0048] To enhance the waterproof performance of the connection between the external antenna and the device body (for cameras, this is the connection between the external antenna and the camera body), the embodiment of the present application utilizes an antenna housing plugged into the device body for assembly. The antenna board cable passes through the portion of the antenna housing that plugs into the device body and then connects to the circuit structure within the device body, enabling signal transmission between the antenna and the circuit structure within the device body while also providing good protection for the cable. A sealing ring is used to reliably seal the assembly gap between the antenna housing and the device body. The assembly gap between the through-hole in the antenna housing through which the cable extends and the cable is sealed with a soft rubber plug that is sleeved onto the cable and at least partially removed and clamped in the through-hole. This achieves a reliable seal at the connection between the external antenna and the device body, providing favorable protection for the antenna's operation.

[0049] According to one aspect of the embodiment of the present application, an external antenna is provided. Figure 1 and Figure 2 The figure shows the overall structure and explosion structure of the external antenna, which is used in electronic equipment. Figure 3 and Figure 4 , Figure 3 and Figure 4 The overall structure and explosion structure of the electronic device with the external antenna are shown in FIG. Figure 3 and Figure 4 The electronic device shown in the figure is a camera, which does not constitute a limitation on the specific type of electronic device. For electronic devices that can use external antennas, such as routers, wireless network cards, etc., the external antennas provided in the embodiments of the present application are applicable.

[0050] like Figure 3 and Figure 4 As shown in FIG, the electronic device 500 includes a device body 200, a plug hole 210 is provided on the device body 200, and a circuit structure 300 is provided in the device body 200. Figure 1 and Figure 2As shown in FIG, the external antenna 100 includes: an antenna housing 110 and an antenna plate 120, wherein the antenna plate 120 is disposed in the antenna housing 110. A plug-in post 111 is disposed on one side of the antenna housing 110, and a sealing ring 112 is provided on the outer periphery of the plug-in post 111. Figures 1 to 4 , the plug-in column 111 is inserted into the plug-in hole 210, and the sealing ring 112 is as Figure 5 The center cross-sectional structure is shown clamped in the plug hole 210 to form a sealed connection.

[0051] Specifically, the plug-in column 111 can be inserted into the plug-in hole 210 by riveting to realize the assembly and fixation of the antenna shell 110 on the device body 200. Of course, the antenna shell 110 can also be assembled and fixed on the device body 200 by using a method in which the clamping blocks are squeezed and deformed and then engaged with each other. Alternatively, the antenna shell 110 can be assembled and fixed on the device body 200 by limiting the plug-in column 111 inside the device body 200 by means of pins, screws, etc. The specific assembly method is not limited here.

[0052] Regarding the sealing between the plug-in post 111 and the inner wall of the plug-in hole 210, specifically, after the plug-in post 111 is inserted into the plug-in hole 210, Figure 5 The portion of the sealing ring 112 shown in the figure that overlaps with the plug-in column 111 and the inner wall of the plug-in hole 210 (actually it is physical interference) will be compressed, so that the sealing ring 112 is clamped between the plug-in column 111 and the inner wall of the plug-in hole 210 to form an interference fit, thereby achieving the purpose of reliable sealing. Here is a sealing design for the assembly gap between the plug-in column 111 and the plug-in hole 210.

[0053] Please combine Figure 2 and Figure 4 A through hole 113 is provided in the plug post 111 , and a cable 121 is connected to the antenna board 120 . The cable 121 passes through the through hole 113 into the interior of the device body 200 and is electrically connected to the circuit structure 300 inside the device body 200 .

[0054] For sealing at through hole 113, see Figure 2 and Figure 5 , a soft rubber plug 122 is sleeved on the cable 121, and the soft rubber plug 122 is at least partially inserted into the through hole 113, and the soft rubber plug 122 is clamped in the through hole 113 to form a sealed connection. Similar to the sealing ring 112 mentioned above, after the soft rubber plug 122 is sleeved on the cable 121 and inserted into the through hole 113, Figure 5The overlapping portions of the middle soft rubber plug 122, the cable 121, and the inner wall of the through-hole 113 are compressed, causing the soft rubber plug 122 to be clamped between the cable 121 and the inner wall of the through-hole 113 to form an interference fit, thereby achieving a reliable seal between the cable 121 and the inner wall of the through-hole 113. Based on this, combined with the sealing effect of the sealing ring 112 on the plug post 111 and the inner wall of the plug hole 210, the overall waterproof performance of the connection between the external antenna 100 and the device body 200 is improved.

[0055] To sum up, in the external antenna 100 provided in the embodiment of the present application, the antenna shell 110 is connected to the plug hole 210 of the device body 200 through the plug-in column 111 set on one side to realize the installation of the external antenna 100 on the device body 200. For the electrical connection between the antenna board 120 and the circuit structure 300 in the device body 200, a cable 121 passing through the through hole 113 inside the plug-in column 111 is used to realize it, so that the plug-in column 111 can play a certain protective role for the cable 121.

[0056] Based on the above structural design, there are two main locations that need to be sealed at the connection between the external antenna 100 and the device body 200. One of them is the assembly gap between the plug-in column 111 and the inner wall of the plug-in hole 210. Here, a clamping sealing ring 112 is used to seal and waterproof. The other is the gap between the cable 121 and the inner wall of the through hole 113. Considering that the gap is large, it is difficult for the sealing ring to achieve reliable sealing. Therefore, a soft rubber plug 122 is provided. The soft rubber plug 122 is sleeved on the cable 121 and at least partially inserted into the through hole 113. The soft rubber plug 122 is squeezed by the inner wall of the through hole 113 so that the soft rubber plug 122 is tightly wrapped around the outer periphery of the cable 121, and at the same time, the gap between the cable 121 and the inner wall of the through hole 113 is tightly filled, thereby achieving sealing inside the through hole 113, so that the waterproof performance of the connection between the external antenna 100 and the device body 200 is effectively improved.

[0057] Regarding the specific structure of the soft rubber plug 122, this application further proposes an implementation method. Figure 5 , and combined with Figure 6 , Figure 6 The explosion structure of the soft rubber plug 122 is shown in FIG. As shown in the figure, the soft rubber plug 122 includes a sealing section 1221 and a limiting section 1222 adjacent to each other. The sealing section 1221 and the limiting section 1222 are both sleeved on the cable 121. The sealing section 1221 is inserted into the through hole 113, and the limiting section 1222 is located at the end of the sealing section 1221 facing the inside of the antenna housing 110 ( Figure 5 The side of the limiting section 1222 protrudes from the sealing section 1221, and the limiting section 1222 and the through hole 113 face inward ( Figure 5The inner wall around the left end of the through hole 113 (in the perspective view) abuts to limit the insertion depth of the soft rubber plug 122 as a whole in the through hole 113.

[0058] In this embodiment, the sealing section 1221 of the soft rubber plug 122 is responsible for squeezing and inserting into the through hole 113 to reliably seal the inside of the through hole 113. At the same time, in order to prevent excessive force from causing the soft rubber plug 122 to be completely inserted into the through hole 113 and difficult to remove, the inward end of the sealing section 1221 also has a side-protruding limiting section 1222. In this way, after the sealing section 1221 is fully inserted into the through hole 113, the side-protruding part of the limiting section 1222 from the sealing section 1221 will abut against the inner wall around the inner end of the through hole 113, thereby limiting the insertion depth of the soft rubber plug 122. At the same time, the abutment between the limiting section 1222 and the inner wall around the inward end of the through hole 113 can further increase the contact area between the soft rubber plug 122 as a whole and the inner wall of the antenna shell 110 to achieve a better sealing effect.

[0059] In order to ensure that the sealing ring 112 can achieve a stable and reliable sealing effect, Figure 7 As shown in the exploded structure of the middle sealing ring 112 , an annular positioning groove 114 is provided on the outer periphery of the plug-in column 111 , and the sealing ring 112 is sleeved and fixed in the positioning groove 114 .

[0060] In this embodiment, the sealing ring 112 is fixedly sleeved in the positioning groove 114 on the outer periphery of the plug-in column 111. During the process of inserting the plug-in column 111 into the plug-in hole 210, the sealing ring 112 will be restricted by the side wall of the positioning groove 114. Therefore, when the sealing ring 112 is squeezed against the inner wall of the plug-in hole 210, the sealing ring 112 can still remain in the positioning groove 114, thereby ensuring the accuracy of the position of the sealing ring 112 and ensuring that the sealing ring 112 can provide a reliable seal for the assembly gap between the plug-in column 111 and the plug-in hole 210 after assembly.

[0061] Regarding the position design of the sealing ring 112, this application proposes an implementation method. Figure 5 and Figure 7 , and further combined with Figure 8 The explosion structure between the middle plug-in column 111 and the plug-in hole 210. Figure 5 and Figure 8 As shown in FIG, a docking portion 220 is formed on the device body 200, and a plug hole 210 is formed in the docking portion 220. A step structure 115 is provided on the periphery of the plug post 111 adjacent to the antenna housing 110. Figure 7 As shown in , the positioning groove 114 includes a first positioning groove 1141 , which is opened on the plug-in column 111 and adjacent to the step structure 115 , and the sealing ring 112 includes a first sealing ring 1121 sleeved and fixed in the first positioning groove 1141 .

[0062] like Figure 5 and Figure 7 As shown in the figure, after the plug-in column 111 is inserted into the plug-in hole 210, the step surface 1151 on the step structure 115 facing away from the antenna housing 110 abuts against the end of the docking part 220, and the first sealing ring 1121 is pressed into the first positioning groove 1141 by the inner wall at the end of the docking part 220.

[0063] To enhance the stability of the external antenna 100's installation, the plug post 111 is inserted into a raised docking portion 220 on the device body 200. Once inserted and installed, the docking portion 220 radially limits the plug post 111, ensuring the stability of the external antenna 100. Furthermore, a stepped structure 115 is provided at the bottom end of the plug post 111 (i.e., where the plug post 111 meets the antenna housing 110). This step 115 abuts against the end of the docking portion 220 to limit the insertion depth of the plug post 111. On the basis of the above-mentioned structural setting, the gap between the step structure 115 and the end of the docking part 220 is the most likely to allow water to enter. In order to reliably seal this place, a first positioning groove 1141 is opened at the position where the plug-in column 111 is adjacent to the step structure 115, and a first sealing ring 1121 is set in the first positioning groove 1141, so that after the plug-in column 111 is inserted into the docking part 220, the first sealing ring 1121 will be pressed into the first positioning groove 1141 by the inner wall at the end of the docking part 220, and the first sealing ring 1121 fits tightly against the surface of the docking part 220 and the plug-in column 111 to seal the assembly gap between the two.

[0064] Considering that the first sealing ring 1121 may fail to seal after being in a compression deformation state for a long time, in order to further ensure the sealing performance after long-term use, Figure 7 As shown in FIG, the positioning groove 114 may further include a second positioning groove 1142, the second positioning groove 1142 is opened on the plug-in column 111 and is located at the end of the first positioning groove 1141 and the plug-in column 111 ( Figure 7 The sealing ring 112 may further include a second sealing ring 1122 which is sleeved and fixed in the second positioning groove 1142. Figure 5 As shown in the figure, after the plug-in column 111 is inserted into the plug-in hole 210, the second sealing ring 1122 is pressed into the second positioning groove 1142 by the inner wall of the docking part 220, so that the assembly gap between the plug-in column 111 and the inner wall of the docking part 220 is reliably sealed through the cooperation between the second sealing ring 1122 and the first sealing ring 1121.

[0065] In order to further improve the sealing effect, the present application also improves the structure of the second sealing ring 1122. Figure 7 As shown in FIG, the outer periphery of the second sealing ring 1122 is formed with a plurality of convex rings 11221 spaced apart from each other. Figure 7 Two are taken as an example, which does not constitute a limitation on the specific number of the protruding rings 11221. Each protruding ring 11221 abuts against the inner wall of the docking portion 220 to be pressed.

[0066] By designing multiple convex rings 11221 that are spaced apart from each other on the outer periphery of the second sealing ring 1122 and can be pressed by the inner wall of the docking part 220, after assembly, the multiple convex rings 11221 can close the gap between the plug-in column 111 and the inner wall of the docking part 220 at multiple spaced apart positions to achieve a more complete sealing effect.

[0067] Regarding the specific structure of the antenna housing 110, this application also proposes an implementation method. Figure 2 As shown, the antenna housing 110 includes a first housing 1101 and a second housing 1102 that are buckled together. The first housing 1101 and the second housing 1102 are fixed and sealed by welding (for example, ultrasonic welding, etc.).

[0068] Specifically, taking the first shell 1101 and the second shell 1102 as plastic parts, and using ultrasonic welding as an example, ultrasonic welding uses high-frequency vibration waves to transmit to the surfaces of the first shell 1101 and the second shell 1102. Under pressure, the first shell 1101 and the second shell 1102 rub against each other to generate heat energy, and the plastic melts and forms a fusion between the molecular layers, and finally solidifies into one piece.

[0069] During ultrasonic welding, the initial area of ​​the first shell 1101 and the second shell 1102 must be small enough to concentrate the energy and reduce the overall energy required for melting and fusing the plastic. Figure 2 As shown in FIG, the fuse (also called fuse column or ultrasonic line) is a raised triangular column 116 provided on the interface between the second shell 1102 and the first shell 1101. The physical structure range of the triangular column 116 is Figure 2 The area marked with the middle hatched line has a pointed top, which is used to focus energy on the tip of the triangular column 116. The heat accumulated at the tip forms a uniform plastic melt flow in the entire welding interface, and finally after solidification, the first shell 1101 and the second shell 1102 are completely joined around the edge, thereby achieving the sealing of the internal space after the first shell 1101 and the second shell 1102 are fixed.

[0070] According to another aspect of the embodiment of the present application, an electronic device is provided. Figure 3, the following text and the accompanying drawings all take the camera as an example, Figure 3 As shown, the electronic device 500 includes a device body 200 and an external antenna 100 in any of the above embodiments. The external antenna 100 is connected to the device body 200. The specific connection method between the external antenna 100 and the device body 200 can refer to the content mentioned in the relevant embodiments of the external antenna 100 described above, and the details will not be repeated here.

[0071] The electronic device 500 provided in the embodiment of the present application adopts the external antenna 100 in the above embodiment to be connected to the device body 200, which can improve the waterproof performance of the connection between the external antenna 100 and the device body 200 to ensure that the electronic device 500 is stable and reliable when working in outdoor environments.

[0072] In order to adjust the direction of the external antenna 100 to enhance its signal strength in different situations, the plug post 111 can be inserted into the plug hole 210 in a rotating manner. In this regard, considering that the cable 121 is passed through the plug post 111, in order to prevent the plug post 111 from excessively rotating and causing the cable 121 to be entangled and damaged, a limited position structure is also provided for the rotation of the plug post 111. For details, please refer to Figure 9 In the explosion state, a first annular protrusion 211 is provided in the plug-in hole 210 on the device body 200, a second annular protrusion 117 is provided on the outer periphery of the plug-in column 111, and a first rotation limit block 2111 and a second rotation limit block 1171 are respectively provided on the two sides facing each other between the first protrusion 211 and the second protrusion 117.

[0073] like Figure 5 As shown in FIG, after the plug-in column 111 is inserted into place, the first protrusion 211 and the second rotation limit block 1171 are aligned along the axial direction of the plug-in hole 210 ( Figure 5 The left and right directions of the viewing angle, that is, the depth direction of the plug hole 210) abut against each other to limit the insertion depth of the plug post 111. Similarly, the second protrusion 117 and the first rotation limit block 2111 also abut against each other along the axial direction of the plug hole 210, except that the abutment between the second protrusion 117 and the first rotation limit block 2111 is not located at Figure 5 On the cross section taken.

[0074] When the plug-in column 111 rotates to the maximum angle, the first rotation limit block 2111 and the second rotation limit block 1171 abut against each other along the circumference of the plug-in column 111. Figure 10 and Figure 11 , Figure 11 Shown Figure 10As shown in the cross-sectional structure along AA, taking the maximum rotation angle of the plug-in column 111 as 180° and the rotation range from vertical upward to vertical downward as an example, when the external antenna 100 rotates to the vertical upward state, the lower end of the first rotation limit block 2111 and one end of the second rotation limit block 1171 abut against each other along the circumference of the plug-in column 111, and the external antenna 100 can no longer rotate in the clockwise direction. Figure 11 On the basis, the external antenna 100 is rotated in the counterclockwise direction until it is vertically downward. Figure 12 The status shown is Figure 12 As shown, the upper end of the first rotation limiter 2111 and the other end of the second rotation limiter 1171 now abut against each other along the circumference of the plug post 111, preventing the external antenna 100 from further counterclockwise rotation. Based on the above principle, the rotation range of the external antenna 100 is limited to prevent excessive rotation from causing entanglement or even damage to the internal cable 121.

[0075] Regarding the method of assembling and fixing the external antenna 100 to the device body 200, this application proposes an implementation scheme. Figure 13 , Figure 13 The exploded structure at the plug hole 210 in the device body 200 is shown. The plug post 111 has a through portion 1111 that completely passes through the plug hole 210. The outer periphery of the through portion 1111 is provided with a clamping portion 1112. The external antenna 100 also includes a clamping member 130. The clamping member 130 is clamped into the clamping portion 1112 and abuts against the inner wall of the device body 200 to limit and fix the plug post 111 relative to the device body 200 along the axial direction of the plug hole 210, while also ensuring the normal rotation of the plug post 111. Specifically, the clamping portion 1112 can be Figure 13 The card slot shown in FIG, accordingly, the card connector 130 is Figure 13 In addition to the elastic insert shown in the figure, the clamping portion 1112 can also be a slot, and the clamping member 130 can correspondingly adopt a pin, which is inserted into the slot to form a clamping connection to limit and fix the plug-in column 111.

[0076] Existing external antennas are mostly assembled and fixed to the device body using a threaded connection between a stud and a nut. This method results in the external antenna being fixed at the angle at which the nut and stud are tightened, making it impossible to adjust the antenna's direction. Rotating the antenna to adjust its direction will cause the nut and stud to loosen, causing the antenna to shake or even come loose.

[0077] In this embodiment, a snap-fit ​​portion 1112 is provided on the through portion 1111 through which the plug-in post 111 completely passes through the plug-in hole 210, and the snap-fit ​​member 130 is used to engage the snap-fit ​​portion 1112 on the inner side of the plug-in hole 210 and abut against the inner wall of the device body 200. This not only enables the plug-in post 111 to be limited and fixed while ensuring the rotation adjustment of the external antenna 100, but also facilitates the assembly operation of the external antenna 100 on the device body 200, thereby improving assembly efficiency.

[0078] Furthermore, on the basis that the external antenna 100 is assembled and fixed to the device body 200 and can rotate relative to the device body 200, combined with the principle description of the sealing ring 112 in the above-mentioned embodiments of the external antenna 100, it can be seen that there is a large contact area and a large interaction force between the sealing ring 112 mounted on the plug-in column 111 and the inner wall of the plug-in hole 210, that is, there is a large friction force between the sealing ring 112 and the inner wall of the plug-in hole 210. This large friction force can provide damping to the rotation of the external antenna 100, so that after the external antenna 100 is rotated to the desired orientation, the external antenna 100 will hover in the current orientation and will not rotate easily, thereby providing reliable protection for the signal reception and transmission of the external antenna 100.

[0079] When the electronic device 500 is Figure 14 Regarding the camera 510 shown, the present application proposes an embodiment of the structure of the device body 200. For details, please refer to the exploded structure shown. The device body 200 includes a front housing assembly 230, a bracket assembly 240, and a rear housing assembly 250. The front housing assembly 230 and the rear housing assembly 250 are interlocked and connected. Specifically, they can be fixed to each other by means of snaps, threaded fasteners, etc., and a sealing ring is provided at the joint to ensure sealing performance. Of course, ultrasonic welding, as described above in the relevant description of the antenna housing 110, can also be used to achieve mutual fixation and sealing between the front housing assembly 230 and the rear housing assembly 250. The bracket assembly 240 is disposed in the internal space formed by the interlocking of the front housing assembly 230 and the rear housing assembly 250.
