Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic products, in particular to an electric connection assembly and a smart wearable device. BACKGROUND

[0002] In related technologies, a smart wearable device such as a virtual reality (VR) / mixed reality (MR) device usually needs to be connected to a power cord for power supply during use. Since the user may move in a large amplitude during use of the smart wearable device, the smart wearable device will move accordingly with the movement of the user's head. When the electronic device moves, the power cord may be pulled, which may cause the connection between the power cord and the smart wearable device to loosen, and further may cause the device to lose power. Alternatively, when the smart wearable device falls, it may also cause the connection between the power cord and the smart wearable device to loosen.

[0003] Therefore, related technologies propose that the connection between the power cord and the smart wearable device can be achieved by an electric connection structure with a self-locking function at the connection position. In related technologies, the electric connection structure with the self-locking function usually requires the user to insert the connection terminal of the power cord into the power supply hole of the smart wearable device from a specific angle, and then manually rotate the connection terminal of the power cord by a certain angle to electrically connect the connection terminal of the power cord with the power supply hole and to lock the connection terminal of the power cord. However, since the connection terminal of the power cord needs to be inserted from a specific angle and needs to be rotated by a specific angle to supply power and lock, the user usually cannot achieve blind insertion of the power cord in a relatively dark environment, which causes the problem of inconvenient connection of the power cord with the power supply hole. SUMMARY

[0004] Embodiments of the present application provide an electric connection assembly and a smart wearable device, which can solve the problem of inconvenient connection of the electric connection structure with the self-locking function in related technologies.

[0005] In a first aspect, an electric connection assembly is provided, comprising:

[0006] The female seat comprises a plug-in portion and a second limiting portion, the plug-in portion comprises a power connection portion and a ground connection portion, and the power connection portion and the ground connection portion are concentric and annular members arranged at intervals.

[0007] The female seat comprises a plug-in portion and a second limiting portion, the plug-in portion comprises a power connection portion and a ground connection portion, and the power connection portion and the ground connection portion are concentric and annular members arranged at intervals.

[0008] When the plug-in portion is inserted into the plug-in slot, the grounding terminal contacts the side wall of the grounding connection portion, the power terminal contacts the side wall of the power connection portion, and the first limiting portion and the second limiting portion engage in a limiting cooperation.

[0009] In a second aspect, a smart wearable device is provided, including a wearable device body and a connecting cable, wherein the wearable device body includes the female connector in the electrical connection assembly described in the first aspect, and the connecting cable includes the male connector in the electrical connection assembly described in the first aspect.

[0010] In this embodiment, by making the power connection portion and ground connection portion of the female connector concentric and spaced annular members, and by providing a first terminal group in the male connector's insertion slot, the female connector can be smoothly inserted into the working insertion slot regardless of the angle from which it is inserted. After insertion, the ground terminal and the power terminal are always in contact with the sidewall of the ground connection portion, ensuring a stable electrical connection between the first terminal group and the female connector. Furthermore, by including a first limiting portion in the male connector and a second limiting portion in the female connector, the first and second limiting portions are always engaged after insertion, regardless of the angle from which the female connector's insertion portion is inserted into the working insertion slot. This improves the convenience of the electrical connection process, as it eliminates the need for insertion at a specific angle and rotation after insertion to achieve electrical connection. In addition, by making the length of the grounding terminal greater than the length of the power supply terminal, the grounding terminal contacts first and the power supply terminal contacts last during the insertion of the male connector into the female connector, thus avoiding circuit breakdown problems caused by electrostatic discharge.

[0024] The electrical connection components and smart wearable devices provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0025] Please see Figures 1 to 11 This application provides an electrical connection component, including:

[0026] Male connector 100, the male connector 100 includes a plug groove 110 and a first limiting part 120, the plug groove 110 is annular, and the inner wall of the plug groove 110 is provided with a first terminal group 140, the first terminal group includes a power terminal 142 and a ground terminal 141, the length of the ground terminal 141 is greater than the length of the power terminal;

[0027] The female connector 200 includes a plug-in portion 220 and a second limiting portion 240. The plug-in portion 220 includes a power connection portion 222 and a ground connection portion 221. The power connection portion 222 and the ground connection portion 221 are concentric and spaced-apart annular components.

[0028] When the plug-in portion 220 is inserted into the plug-in slot 110, the grounding terminal 141 contacts the side wall of the grounding connection portion 221, the power terminal 142 contacts the side wall of the power connection portion 222, and the first limiting portion 120 and the second limiting portion 240 are in a limiting engagement.

[0029] In some embodiments of this application, the female connector 200 further includes a female connector circuit board 210, and the insertion portion 220 is a protruding insertion portion 220 from the surface of the female connector circuit board 210. The insertion groove 110 is circular, the insertion portion 220 is circular, and the insertion portion 220 matches the insertion groove 110. The second limiting portion 240 is annular, and the axis of the second limiting portion 240 coincides with the axis of the insertion portion 220.

[0030] When the plug-in portion 220 is inserted into the plug-in slot 110, the first terminal group 140 contacts the side wall of the plug-in portion 220, the first terminal group 140 is electrically connected to the female circuit board 210 through the plug-in portion 220, and the first limiting portion 120 and the second limiting portion 240 are mutually limiting and cooperating.

[0031] The aforementioned electrical connection components can be applied to various scenarios involving pluggable connections between cables and devices. Specifically, in practical applications, one of the devices and the cable includes the aforementioned male connector 100, and the other includes the aforementioned female connector 200.

[0032] The aforementioned first limiting portion 120 may be a limiting portion capable of engaging with the annular second limiting portion 240 in the female connector 200. For example, when the second limiting portion 240 is an annular groove, the first limiting portion 120 may include a limiting protrusion capable of being embedded in the annular groove or other limiting structures with similar functions. As another example, when the second limiting portion 240 is an annular protrusion, the first limiting portion 120 may include a limiting protrusion capable of being embedded in the gap between the second limiting portion 240 and the female connector circuit board 210, or other limiting structures with similar functions.

[0033] It is understood that the aforementioned male connector 100 may also include a wiring harness 191 and a male connector circuit board 190, wherein the wiring harness 191 can be electrically connected to the terminals in the first terminal group 140 through the male connector circuit board 190.

[0034] In some embodiments of this application, the power terminal 142 is a GND terminal, the ground terminal 141 is a VBUS terminal, and when the plug portion 220 is inserted into the plug slot 110, the distance between the ground terminal 141 and the female circuit board 210 is less than the distance between the power terminal 142 and the female circuit board 210.

[0035] It is understood that the protrusion heights of the grounding connection portion 221 and the power connection portion 222 relative to the female circuit board 210 can be the same. The length of the grounding terminal 141 can be greater than the length of the power terminal 142, so that when the plug portion 220 is inserted into the plug slot 110, the distance between the grounding terminal 141 and the female circuit board 210 is less than the distance between the power terminal 142 and the female circuit board 210.

[0036] Please see Figure 5 In some embodiments of this application, the power connection portion 222 and the ground connection portion 221 can be two concentric and spaced-apart annular electrodes. The power connection portion 222 can be located inside or outside the ground connection portion 221, depending on the specific configuration. When the plug portion 220 is inserted into the plug slot 110, the ground terminal 141 can contact the outer or inner wall of the ground connection portion 221. Correspondingly, when the plug portion 220 is inserted into the plug slot 110, the power terminal 142 contacts the inner or outer wall of the power connection portion 222, depending on the specific configuration.

[0037] In this embodiment, by making the power connection portion 222 and the ground connection portion 221 of the plug portion 220 of the female connector 200 concentric and spaced annular members, and by providing a first terminal group 140 in the plug slot 110 of the male connector 100, the plug portion 220 of the female connector 200 can be smoothly inserted into the working plug slot 110 from any angle. After insertion, it can be ensured that the ground terminal is in contact with the side wall of the ground connection portion 221 and the power terminal is in contact with the side wall of the power connection portion 222, so that a stable electrical connection is maintained between the first terminal group 140 and the female connector 200. Meanwhile, by including a first limiting part 120 in the male connector 100 and a second limiting part 240 in the female connector 200, regardless of the angle at which the female connector 200's insertion part 220 is inserted into the working insertion slot 110, the first limiting part 120 and the second limiting part 240 can be guaranteed to engage in a limiting fit after the insertion part 220 is inserted into the insertion slot 110. Thus, since the male connector 100 and female connector 200 do not need to be inserted from a specific angle, and no specific angle needs to be rotated after insertion to achieve electrical connection, the convenience of the electrical connection structure connection process is improved. Furthermore, by making the length of the GND terminal greater than the length of the VBUS terminal, the GND terminal contacts first and the VBUS terminal contacts second during the insertion of the male connector 100 into the female connector 200, avoiding circuit breakdown problems caused by electrostatic discharge.

[0038] Optionally, the outer diameter of the power connection portion 222 is smaller than the inner diameter of the ground connection portion 221, and when the plug portion 220 is inserted into the plug slot 110, the ground terminal 141 contacts the outer side wall of the ground connection portion 221, and the power terminal 142 contacts the inner side wall of the power connection portion 222.

[0039] In this embodiment, by making the outer diameter of the power connection portion 222 smaller than the inner diameter of the ground connection portion 221, and when the plug portion 220 is inserted into the plug slot 110, the ground terminal 141 contacts the outer side wall of the ground connection portion 221, and the power terminal 142 contacts the inner side wall of the power connection portion 222. In this way, the power terminal 142 can be separated from the ground connection portion 221 by the power connection portion 222 to avoid electrical conduction between the power terminal 142 and the ground connection portion 221. At the same time, the ground terminal 141 can be separated from the power connection portion 222 by the ground connection portion 221 to avoid electrical conduction between the ground terminal 141 and the power connection portion 222, thereby helping to ensure the stability of the electrical connection between the internal circuits of the electrical connection component.

[0040] Optionally, the male connector 100 includes a first housing 180, a support body 150, and a second terminal group 143. The first housing 180 includes an open end 181, the support body 150 is connected to the open end 181, and the support body 150 includes a protruding section 151 extending from one side of the open end 181. The insertion groove 110 is formed at the end of the protruding section 151 opposite to the first housing 180.

[0041] One end of a terminal in the second terminal group 143 passes through the support 150 and extends to the end of the protrusion 151 opposite to the first housing 180. The female connector 200 includes a pad group 260 corresponding to the second terminal group 143.

[0042] When the plug portion 220 is inserted into the plug slot 110, the terminals in the second terminal group 143 contact the pad group 260.

[0043] The first housing 180 is a cylindrical hollow housing, and the open end 181 of the first housing 180 is in communication with the internal space of the first housing 180.

[0044] The aforementioned support 150 can be used to support or mount related devices in the male seat 100. The support may also consist only of the aforementioned protruding section 151. Furthermore, please refer to... Figure 1 and Figure 2 In some embodiments of this application, the support 150 may further include an embedded section 152 connected to the protruding end. The embedded section 152 is hollow cylindrical and fits against the inner wall of the first housing 180. Thus, the support 150 and the first housing 180 together form a closed mounting cavity, in which the relevant components in the male connector 100 can be installed. The support 150 may be various insulating supports, for example, a support 150 made of plastic.

[0045] Please see Figure 2 In some embodiments of this application, the male connector 100 may further include a second housing 182, which covers the surface of the first housing 180. The second housing 182 has an opening for the terminals in the male connector 100 to extend out and for the insertion portion 220 of the female connector 200 to be inserted. Specifically, the second housing 182 has an annular opening for insertion into the insertion groove 110 to expose the insertion groove 110. In addition, the middle part of the second housing 182 also has an opening for the terminals in the second terminal group 143 to extend out.

[0046] The aforementioned pad group 260 may include at least one pad, and the number of pads in the pad group 260 may be equal to the number of terminals in the second terminal group 143. The pads in the pad group 260 may be pad structures disposed in the female connector circuit board 210, or they may be electrical connection areas formed by exposed copper on the female connector circuit board 210.

[0047] The terminal types in the second terminal group 143 described above can be other types of terminals besides GND terminals and VBUS terminals, for example, they can be signal terminals.

[0048] In this embodiment, by including a second terminal group 143 in the male connector 100, with one end of a terminal in the second terminal group 143 passing through the support body 150 and extending to the end of the protruding section 151 opposite to the first housing 180, and the female connector 200 including a pad group 260 corresponding to the second terminal group 143, when the insertion part 220 is inserted into the insertion slot 110, the terminal in the second terminal group 143 contacts the pad group 260, thus further increasing the number of terminals connected between the male connector 100 and the female connector 200.

[0049] Optionally, the pad group 260 includes a circular pad 262 and an annular pad 261. The circular pad 262, the annular pad 261 and the power connection portion 222 are concentric, and the outer diameter of the annular pad 261 is smaller than the inner diameter of the power connection portion 222, and the diameter of the circular pad 262 is smaller than the inner diameter of the annular pad 261.

[0050] The second terminal group 143 includes a first signal terminal 1432 and a second signal terminal 1431, wherein when the plug portion 220 is inserted into the plug slot 110, the first signal terminal 1432 contacts the annular pad 261, and the second signal terminal 1431 contacts the circular pad 262.

[0051] In this application, both the first signal terminal 1432 and the second signal terminal 1431 are signal terminals, and the specific terminal types can be customized with different pin definitions according to the charging scheme. For example, in some embodiments of this application, one of the first signal terminal 1432 and the other of the second signal terminal 1431 is a DP terminal and the other is a DM terminal. As another example, in some embodiments of this application, one of the first signal terminal 1432 and the other of the second signal terminal 1431 is a CC terminal and the other is a VCON terminal.

[0052] It should be noted that, in the embodiments of this application, the number of grounding terminal 141, power supply terminal 142, first signal terminal 1432 and second signal terminal 1431 can be set as needed. For example, each type of terminal can be greater than or equal to one.

[0053] In this embodiment, by making the pad group 260 include a circular pad 262 and an annular pad 261, the circular pad 262, the annular pad 261 and the power connection portion 222 are coaxial, and the outer diameter of the annular pad 261 is smaller than the inner diameter of the power connection portion 222, and the diameter of the circular pad 262 is smaller than the inner diameter of the annular pad 261; the second terminal group 143 includes a first signal terminal 1432 and a second signal terminal 1431, wherein, when the plug portion 220 is inserted into the plug slot 110, the first signal terminal 1432 contacts the annular pad 261, and the second signal terminal 1431 contacts the circular pad 262, it is beneficial to improve the utilization rate of the internal space of the ground connection portion 221, so that more terminal connection areas are provided inside the ground connection portion 221.

[0054] Optionally, the male seat 100 includes a first housing 180, a support body 150, and a hook assembly 130. The first housing 180 includes an open end 181. The support body 150 is connected to the open end 181, and the support body 150 includes a protruding section 151 extending from one side of the open end 181. The insertion groove 110 is formed at the end of the protruding section 151 opposite to the first housing 180.

[0055] The hook assembly 130 includes at least two hooks, which are arranged at intervals around the protruding section 151. One end of each hook is located inside the first housing 180, and the other end of each hook extends through the opening end 181 to the outside of the first housing 180. The end of each hook outside the first housing 180 has a bent portion that bends toward the protruding section 151. The first limiting portion 120 includes the bent portion.

[0056] The second limiting portion 240 includes a limiting protrusion extending outward from the outer side wall of the insertion portion 220, and when the insertion portion 220 is inserted into the insertion groove 110, the limiting protrusion and the first limiting portion 120 limit each other in the axial direction of the insertion groove 110.

[0057] In some embodiments of this application, a first limiting gap 230 is provided between the limiting protrusion and the female circuit board 210; when the plug-in portion 220 is inserted into the plug-in slot 110, the bent portion of the hook is embedded in the first limiting gap 230 so that the first limiting portion 120 and the second limiting portion 240 are limited and engaged.

[0058] The number of the aforementioned hooks can be set as needed; for example, please refer to [link / reference]. Figure 1 In some embodiments of this application, the hook assembly 130 includes two hooks.

[0059] Please see Figure 5 In some embodiments of this application, the female connector 200 further includes a female connector plastic body 250, which is located between the insertion portion 220 and the limiting protrusion.

[0060] In this embodiment, the male seat 100 includes a first housing 180, a support body 150, and a hook assembly 130. The first housing 180 includes an open end 181, the support body 150 is connected to the open end 181, and the support body 150 includes a protruding section 151 extending from one side of the open end 181. The insertion groove 110 is formed at the end of the protruding section 151 opposite to the first housing 180. The hook assembly 130 includes at least two hooks, which are arranged at intervals around the protruding section 151. One end of each hook is located inside the first housing 180, and the other end of each hook passes through the open end. 181 extends beyond the first housing 180. The end of the hook outside the first housing 180 has a bent portion that bends toward the protruding section 151. The first limiting portion 120 includes the bent portion. The second limiting portion 240 includes a limiting protrusion extending outward from the outer side wall of the insertion portion 220. When the insertion portion 220 is inserted into the insertion groove 110, the limiting protrusion and the first limiting portion 120 limit each other in the axial direction of the insertion groove 110. In this way, when the male seat 100 and the female seat 200 are inserted and engaged, the connection between the male seat 100 and the female seat 200 can be locked.

[0061] Optionally, the male seat 100 further includes a first support base 161, a second support base 162, and a drive assembly 170. The first support base 161 and the second support base 162 are respectively fixedly disposed within the first housing 180. The at least two hooks include a first hook 131 and a second hook 132. The first hook 131 is rotatably connected to the first support base 161, and the second hook 132 is rotatably connected to the second support base 162. The drive assembly 170 is connected to the first hook 131 and the second hook 132 respectively to drive the first hook 131 to rotate relative to the first support base 161 and to drive the second hook 132 to rotate relative to the second support base 162.

[0062] The shape and specific structure of the first support 161 and the second support 162 can be set according to actual needs. For example, please refer to... Figure 1 In some embodiments of this application, the first hook 131 and the second hook 132 are respectively rod-shaped. Therefore, the first support base 161 and the second support base 162 can be respectively hollow column-shaped. The first hook 131 is inserted into the first support base 161, and the second hook 132 is inserted into the second support base 162. The first hook 131 is rotatably connected to the first support base 161 through the first rotating shaft 133, and the second hook 132 is rotatably connected to the second support base 162 through the second rotating shaft 134.

[0063] Please see Figure 1 and Figure 2 To facilitate the rotation of the first hook 131 relative to the first support base 161, the cross-sectional area of ​​the cavity inside the first support base 161 can be larger than the cross-sectional area of ​​the first hook 131, and the width of the area of ​​the first hook 131 used for connection with the first rotating shaft 133 can be larger than the width of other areas. Thus, the first hook 131 can swing slightly within the first support base 161. Accordingly, please refer to 1 and... Figure 2 In order to facilitate the rotation of the second hook 132 relative to the second support 162, the cross-sectional area of ​​the cavity inside the second support 162 can be made larger than the cross-sectional area of ​​the second hook 132, and the width of the area of ​​the second hook 132 used to connect with the second rotating shaft 134 can be made larger than the width of other areas. In this way, the second hook 132 can swing slightly inside the second support 162.

[0064] The aforementioned drive assembly 170 can be any drive structure capable of driving the first hook 131 and the second hook 132 to rotate around their corresponding rotation axes. For example, please refer to [reference needed]. Figure 1In some embodiments of this application, one end of the first hook 131 located inside the first housing 180 and one end of the second hook 132 located inside the first housing 180 are respectively connected to the driving assembly 170. The driving assembly 170 can drive the tops of the first hook 131 and the second hook 132 to move left and right, thereby causing the first hook 131 to rotate relative to the first support base 161 and the second hook 132 to rotate relative to the second support base 162. Thus, when it is necessary to separate the male seat 100 from the female seat 200, the driving assembly 170 can drive the first hook 131 to rotate clockwise and the second hook 132 to rotate counterclockwise, thereby causing the first hook 131 and the second hook 132 to disengage from the first limiting gap 230, so that the user can directly pull the male seat 100 out of the female seat 200.

[0065] In this embodiment, the male seat 100 further includes a first support base 161, a second support base 162, and a drive assembly 170. The first support base 161 and the second support base 162 are respectively fixedly disposed within the first housing 180. The at least two latches include a first latch 131 and a second latch 132. The first latch 131 is rotatably connected to the first support base 161, and the second latch 132 is rotatably connected to the second support base 162. The drive assembly 170 is connected to the first latch 131 and the second latch 132 respectively to drive the first latch 131 to rotate relative to the first support base 161 and to drive the second latch 132 to rotate relative to the second support base 162. In this way, the user can easily disengage the first latch 131 and the second latch 132 from the first limiting gap 230 through the drive assembly 170 to release the locking state between the male seat 100 and the female seat 200.

[0066] Optionally, the drive assembly 170 includes a first sliding rod 171, a second sliding rod 172, a control rod 173, and a first elastic element 174. The first housing 180 is provided with a first slide rail 163. The first sliding rod 171 and the second sliding rod 172 are slidably disposed in the first slide rail 163.

[0069] The first elastic element 174 can be any type of elastic element, such as a spring or an elastic rope.

[0070] Please see Figure 2 In some embodiments of this application, the first support 161, the first slide rail 163, and the second support 162 are sequentially connected to form a U-shaped bracket, and the top of the first slide rail 163 is open. Simultaneously, a cover plate 192 covers the opening of the first slide rail 163, forming the top wall of the first slide rail 163. Please refer to... Figure 1 A terminal plastic body 1100 is provided between the first slide rail 163 and the protruding section 151 of the support body 150. All terminals in the male connector 100 pass through the terminal plastic body 1100. The male connector 100 also includes a screw 193, which passes through the cover plate 192, the male connector circuit board 190 and the terminal plastic body 1100 in sequence to fix the position of the cover plate 192, the male connector circuit board 190 and the terminal plastic body 1100.

[0071] Please see Figure 9 and Figure 10 When the user needs to connect the male connector 100 and the female connector 200, the insertion slot 110 of the male connector 100 can be aligned with the insertion part 220 of the female connector 200, so that the insertion part 220 of the female connector 200 is inserted into the insertion slot 110. When the insertion part 220 is inserted to the point that the first hook 131 and the second hook 132 are in contact with the limiting protrusion, as insertion continues, under the action of the relative force between the first hook 131 and the limiting protrusion, the first hook 131 can rotate clockwise, and under the action of the relative force between the second hook 132 and the limiting protrusion, the second hook 132 can rotate counterclockwise. That is, the first hook 131 and the second hook 132 open outward relative to each other. At this time, the first sliding rod 171 and the second sliding rod 172 slide towards the control rod 173, thereby pushing the control rod 173 to move upward. When the bent portions of the first hook 131 and the second hook 132 move to below the limiting protrusion, under the pulling force of the first elastic element 174, the control rod 173 is pushed downward, thereby pushing the first sliding rod 171 and the second sliding rod 172 to move in opposite directions, causing the first hook 131 and the second hook 132 to retract inward, so that the bent portions of the first hook 131 and the second hook 132 are respectively embedded in the first limiting gap 230, so as to achieve automatic locking between the male seat 100 and the female seat 200 during the process of pushing the male seat 100.

[0072] In this embodiment, by having a first inclined surface at the end of the first sliding rod 171 facing the control rod 173, the first inclined surface being located on the side of the first sliding rod 171 opposite to the opening end 181, and a second inclined surface at the end of the second sliding rod 172 facing the control rod 173, the second inclined surface being located on the side of the second sliding rod 172 opposite to the opening end 181, and the control rod 173 including a third and a fourth inclined surface opposite to each other, the third inclined surface matching the first inclined surface and the fourth inclined surface matching the second inclined surface, the control rod 173 can slide toward or away from the first inner wall 165; the first elastic member 174 is in an elastically stretched state so that the first inclined surface fits against the third inclined surface and the second inclined surface fits against the fourth inclined surface, thus achieving automatic locking between the male seat 100 and the female seat 200 during the pushing of the male seat 100.

[0073] Optionally, the drive assembly 170 further includes a drive module 175, a second elastic element 176, and a third elastic element 177. The drive module 175 is connected to the end of the control rod 173 away from the receiving groove 164, and the drive module 175 is used to drive the control rod 173 to slide away from the first inner wall 165.

[0074] The second elastic member 176 is disposed between the end of the first sliding rod 171 away from the control rod 173 and the inner wall of the first housing 180, and the second elastic member 176 is in an elastically compressed state to push the first sliding rod 171 to slide toward the control rod 173.

[0075] The third elastic element 177 is disposed between the end of the second sliding rod 172 away from the control rod 173 and the inner wall of the first housing 180, and the third elastic element 177 is in an elastically compressed state to push the second sliding rod 172 to slide toward the control rod 173.

[0076] Among them, the drive module 175 and the aforementioned drive assembly 170 can be various drive structures capable of driving the control lever 173 to slide away from the first inner wall 165, that is, capable of driving... Figure 1 The control lever 173 in the middle is driven by an upward movement mechanism. For example, it could be a pull rod or other similar structure.

[0077] The aforementioned second elastic element 176 and third elastic element 177 can be various types of elastic elements such as springs or torsion springs.

[0078] Please see Figure 11In this embodiment, when the male seat 100 and female seat 200 are locked, the user can use the drive module 175 to slide the control lever 173 away from the first inner wall 165. This causes the second elastic element 176 to push the first sliding rod 171 towards the control lever 173, causing the first latch 131 to rotate clockwise. Conversely, the third elastic element 177 pushes the second sliding rod 172 towards the control lever 173, causing the second latch 132 to rotate counterclockwise, thus unlocking the male seat 100 and female seat 200. After unlocking, the user can directly separate the male seat 100 and female seat 200.

[0079] In this embodiment, by further comprising a drive module 175, a second elastic element 176, and a third elastic element 177, the drive module 175 is connected to the end of the control rod 173 away from the receiving groove 164, and the drive module 175 is used to drive the control rod 173 to slide away from the first inner wall 165; the second elastic element 176 is disposed between the end of the first sliding rod 171 away from the control rod 173 and the inner wall of the first housing 180, and the second elastic element 176 is in an elastically compressed state to push the first sliding rod 171 to slide towards the control rod 173; the third elastic element 177 is disposed between the end of the second sliding rod 172 away from the control rod 173 and the inner wall of the first housing 180, and the third elastic element 177 is in an elastically compressed state. Thus, it is convenient for the user to control the unlocking of the male seat 100 and the female seat 200 based on the drive module 175.

[0080] Optionally, one end of the control rod 173 away from the receiving groove 164 is located outside the first slide rail 163, and the end of the control rod 173 away from the receiving groove 164 is connected to a limiting plate 178, and the limiting plate 178 has a second limiting gap with the outer side wall of the first slide rail 163.

[0081] The drive module 175 includes an elastic shell 1752 and a button 1751. The first shell 180 has a first through hole, which is opposite to the end of the control rod 173 away from the receiving groove 164. The button 1751 is movably embedded in the first through hole. The elastic shell 1752 is a shell-shaped structure that protrudes towards the side of the button 1751. The elastic shell 1752 includes a first elastic arm 1753 and a second elastic arm 1754. The first elastic arm 1753 and the second elastic arm 1754 extend from both sides of the edge of the elastic shell 1752 to the second limiting gap, respectively.

[0082] Please seeFigure 4 When the user presses down on button 1751, button 1751 generates a downward thrust on elastic shell 1752. At this time, elastic shell 1752 is squeezed downward, and the first elastic arm 1753 and the second elastic arm 1754 extend inward and press against the outer wall of the first slide rail 163. At this time, the extension direction changes, and the first elastic arm 1753 and the second elastic arm 1754 push the limiting plate 178 upward, thereby driving the control rod 173 to slide away from the first inner wall 165.

[0083] In this embodiment, the control rod 173, with one end away from the receiving groove 164, extends through the side wall of the first slide rail 163 and beyond it. A limiting plate 178 is connected to the end of the control rod 173 away from the receiving groove 164, and a second limiting gap exists between the limiting plate 178 and the outer side wall of the first slide rail 163. The drive module 175 includes an elastic shell 1752 and a button 1751.
