Description

Technical Field

[0001] The present application relates to the field of machinery, and in particular to a plug-in assembly and a waterproof motor compartment connected to the plug-in assembly. Background Art

[0002] A pool robot is a device used for pool operations and works in a water-filled environment. Therefore, waterproofing of certain parts of the pool robot is extremely important.

[0003] For example, one way to install an external sensor is to use a wiring harness directly connected to the sensor. This connection method requires drilling a hole in the sealed cabin wall, passing the wiring through the hole, and then securing it to the sealed cabin to ensure waterproofing. With this method, once the sensor is fixed and sealed, it is difficult or even impossible to remove and replace, which greatly complicates after-sales and maintenance.

[0004] Another method for installing external sensors is to connect multiple sensors together using an adapter plate and then waterproofing them. This installation method can cause multiple sensors to become entangled during production and assembly, making assembly difficult. Furthermore, if multiple sensors are connected together, if any one becomes damaged, it cannot be replaced individually, requiring all sensors to be replaced simultaneously. This situation complicates production, after-sales service, and repairs, increasing production and after-sales costs. Utility Model Content

[0027] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0028] To facilitate understanding of the technical solutions of the embodiments of the present application, the following describes the related technologies of the embodiments of the present application. The following related technologies can be combined with the technical solutions of the embodiments of the present application as optional solutions, and all of them fall within the scope of protection of the embodiments of the present application.

[0029] The plug-in assembly and its components of the present application are described in detail below with reference to the accompanying drawings. Figure 1 and Figure 2 A reference schematic diagram of a plug and a socket of a plug assembly according to an embodiment of the present application is recorded. Figure 1 is a schematic cross-sectional structural diagram of the plug in the plug assembly, Figure 2 It is a schematic cross-sectional structural diagram of the socket in the plug assembly. Figure 1 The plug shown is Figure 2 The sockets shown together constitute the plug assembly of the present application.

[0030] The plug-in assembly comprises a plug and a socket.

[0031] The plug includes: a plug body 1, the plug body 1 including a first extension portion 101 extending from the plug body 1 to a first side and a second extension portion 102 extending to a second side, wherein the plug can be installed on the bulkhead of the waterproof motor compartment 6 of the automatic pool cleaning device, and the first extension portion 101 is outside the waterproof motor compartment 6, and the second extension portion 102 is inside the waterproof motor compartment 6.

[0032] The socket includes: a socket body 2 corresponding to the first extension portion 101 ; and an annular nut 201 sleeved on the outside of the socket body 2 for connecting the socket body 2 and the first extension portion 101 .

[0033] The plug assembly can be installed in an automatic pool cleaning device. The automatic pool cleaning device can be a device such as an automatic cleaning robot. The automatic pool cleaning device can perform mobile cleaning within a pool-shaped structure, such as a swimming pool, a reservoir, a water tank, or a water trough. Hereinafter, unless otherwise specified, the robot will be used as an example of the automatic pool cleaning device, and the swimming pool will be used as an example of the pool-shaped structure. Because the robot needs to perform cleaning operations in and under water, a waterproof motor compartment is required inside the robot. Electronic components such as a controller, memory, motherboard, battery, and motor are placed in the waterproof motor compartment to isolate such electronic components from water and prevent short circuits. If the electronic components inside the waterproof motor compartment need to be electrically connected to one or more components outside the waterproof motor compartment (such as a distance sensor, depth sensor, etc.), such electrical connection can be achieved using the plug assembly provided in this application. The plug assembly can ensure a waterproof effect and effectively prevent water from the swimming pool from entering the waterproof motor compartment and the plug assembly.

[0034] The plug and the socket are described in detail below.

[0035] like Figure 1 As shown, the plug body 1 includes a first protruding portion 101 and a second protruding portion 102 .

[0036] The first extension 101 and the second extension 102 can be formed integrally with the plug body 1. The first extension 101 is outside the waterproof motor compartment 6, and the second extension 102 is inside the waterproof motor compartment 6. The outer surface of the second extension 102 includes an annular groove. The annular groove is composed of two annular protrusions (e.g. Figure 1 The first annular ridge 1021 and the second annular ridge 1022 are parallel or substantially parallel to each other, and both may protrude in the radial direction of the plug body 1 (i.e., perpendicular to the axial direction of the plug body 1).

[0037] In one embodiment, the radially projecting height of the second annular ridge 1022 along the plug body 1 is greater than or equal to the radially projecting height of the first annular ridge 1021 along the plug body 1. In another embodiment, the radially projecting height of the second annular ridge 1022 along the plug body 1 is less than the radially projecting height of the first annular ridge 1021 along the plug body 1. The relationship between the radially projecting height of the second annular ridge 1022 and the radially projecting height of the first annular ridge 1021 along the plug body 1 can be selectively set based on the angle, inclination, and roughness of the corresponding positions on the inner wall of the waterproof motor compartment 6, as long as the technical principles of the present application are implemented.

[0038] The plug body 1 and the socket body 2 are connected to realize electrical signal connection. The socket body (2) corresponds to the first extension (101). When the socket body 2 is connected to the first extension 101, the head of the socket body 2 is embedded in the first extension 101. At least one metal pin is provided in the socket body 2 or the first extension 101.

[0039] For example, a plurality of metal pins 103 penetrate the plug body 1 so that electrical signals are transmitted between the electronic components outside the waterproof motor compartment 6 and the electronic components inside the waterproof motor compartment 6. For example, the first ends of the plurality of metal pins 103 (e.g. Figure 1 The left end shown in FIG. 1 ) can extend in the direction of the first extension portion 101 (eg, to the left), and the second ends of the plurality of metal pins 103 (eg, Figure 1 The right end shown in FIG100 can extend in the direction of the second extension portion 102 (eg, rightward). The two ends of the metal pin 103 can be connected to the cable and the metal needle tube 203 respectively.

[0040] like Figure 1As shown in FIG, the first protruding portion 101 extends from the plug body 1 to one side (eg Figure 1 The first extension 101 is arranged in a ring shape around a plurality of metal pins 103, so that the space between the annular wall of the first extension 101 and the metal pins 103 can be used to accommodate at least a part of the socket body 2. Figure 2 and Figure 3 The socket body and its plugging relationship with the plug body are further explained.

[0041] The plug body 1 is mounted on the wall of the waterproof motor compartment 6 of the automatic pool cleaning device and can be fixed by a fixing nut 3. The specific installation method is as follows: Figure 1 shown.

[0042] The first extension 101 extends through the bulkhead of the waterproof compartment 6 and out of the waterproof motor compartment 6. The second extension 102 is located within the motor compartment, with its protruding edges (first annular protrusion 1021 and second annular protrusion 1022) engaging the inner wall of the motor compartment, securing the plug body 1 after installation. A fixing nut 3 is disposed on the exterior of the plug body 1. The bulkhead is engaged between the fixing nut 3 and the annular protrusion, thereby securing the plug to the corresponding bulkhead of the waterproof motor compartment 6.

[0043] The fixing nut 3 can be installed on the plug by means of a thread. For example, the outer wall surface of the first extension 101 is provided with a plug thread, and the inner wall surface of the fixing nut 3 is provided with a nut thread corresponding to the plug thread. The fixing nut 3 can be tightened by the plug thread and the nut thread, thereby fixing the plug to the corresponding bulkhead of the waterproof motor compartment 6. When the fixing nut 3 is tightened, the plug is in a state of being installed in the waterproof motor compartment 6, and the fixing nut 3 is opposite to the first annular ridge 1021. The fixing nut 3 is in close contact with the outer surface of the bulkhead of the waterproof motor compartment 6, and the first annular ridge 1021 is in close contact with the inner surface of the bulkhead of the waterproof motor compartment 6. Through the close contact between these elements, the fixing nut 3 can achieve a waterproof effect when fixing the plug to the bulkhead of the waterproof motor compartment 6.

[0044] The plug further includes a plug sealing ring 4. The plug sealing ring 4 is provided on the second extension portion 102. When the plug is installed in the waterproof motor compartment 6, the plug sealing ring 4 can prevent water from entering the waterproof motor compartment 6 along the plug, thereby achieving a better waterproof effect. The plug sealing ring 4 can be installed by snapping. For example, in the embodiment of the present application, the plug sealing ring 4 is provided on two annular protrusions ( Figure 1 The plug seal ring 4 can be, for example, Figure 1 The O-ring shown in FIG 1 has an annular groove equal to or slightly smaller than the thickness of the plug sealing ring 4, thereby ensuring the plug sealing ring 4's waterproofing effectiveness. Once installed within the annular groove, the side surface of the plug sealing ring 4 can protrude somewhat beyond the groove. When the plug is installed in the waterproof motor compartment 6, the first annular ridge 1021, the second annular ridge 1022, and the plug sealing ring 4 respectively contact the inner surface of the bulkhead of the waterproof motor compartment 6, preventing water from entering the waterproof motor compartment 6 along the plug, thus providing a seal.

[0045] The socket in the plug assembly of the present application is described in detail below with reference to the accompanying drawings. Figure 2 Schematic diagram of the cross-sectional structure of the socket in the plug assembly of this application. Figure 2 As shown, the socket includes a socket body 2 and a ring nut 201.

[0046] A plurality of metal pin tubes 203 are provided in the socket body 2, corresponding to the plurality of metal pins 103 in the plug described above. When the plug is connected to the socket, the metal pins 103 are inserted into the corresponding metal pin tubes 203 to complete the electrical connection.

[0047] An annular nut 201 is disposed outside the socket body 2, and a first end of the annular nut 201 is connected to the socket body 2. A second predetermined space 202 is defined between the inner wall surface of the annular nut 201 and the outer wall surface of the socket body 2. The second predetermined space 202 can accommodate the first extension portion 101 of the plug corresponding to the socket.

[0048] In an embodiment of the present application, the annular nut 201 is a cylindrical structure, the "bottom" of the cylindrical structure corresponds to the first end of the annular nut 201, and the side wall / barrel body of the cylindrical structure extends along the axial direction of the socket body 2.

[0049] The socket body 2 includes an annular protrusion 204. When the socket and the corresponding plug are plugged together, the socket body 2 is embedded in the first protrusion 101 to limit the head of the first protrusion 101. The first side of the annular protrusion 204 (for example Figure 2The annular protrusion 204 (shown in the figure) contacts the inner edge of the annular nut 201, thereby preventing water from seeping into the plug assembly through the gap between the annular nut 201 and the socket body 2. The inner wall surface of the annular nut 201 has an annular nut thread that can engage with the plug thread of the plug to achieve the connection between the socket and the plug. When the annular nut thread engages with the plug thread of the plug, the inner edge of the annular nut 201 abuts against the annular protrusion 204 of the socket body 2, thereby ensuring a tight connection between the socket body 2 and the plug body 1 and preventing water from seeping into the plug assembly through the gap between the annular nut 201 and the socket body 2.

[0050] To achieve a better waterproofing effect, a socket sealing ring 5 may also be provided on the socket. For example, the socket sealing ring 5 is disposed between the inner wall surface of the annular nut 201 and the outer wall surface of the socket body 2. When the socket is plugged into the corresponding plug, the socket sealing ring 5 can prevent water from entering the plug assembly. In this embodiment, as the annular nut threads engage with the plug threads of the plug, the annular protrusion 204 and the first extension 101 of the plug described above contact and compress the socket sealing ring 5 from both left and right sides, causing the sealing ring to fill and seal the gap / space between the annular nut 201, the annular protrusion 204, and the first extension 101, thereby preventing water from seeping into the plug assembly.

[0051] Another specific embodiment of the present application provides a waterproof motor compartment, which includes the above-mentioned plug-in assembly. The plug-in assembly is the same as or similar to the plug-in assembly described above in conjunction with the drawings, and will not be described again here.

[0052] When the plug of the plug assembly is installed in the waterproof motor compartment, the first extension 101 of the plug body 1 extends from the bulkhead of the motor compartment, while the second extension 102 is located inside the motor compartment. The first annular lip 1021, the plug sealing ring 4, and the second annular lip 1022 are embedded in the waterproof motor compartment and contact the inner surface of the bulkhead of the waterproof motor compartment. When the internal threads of the fixing nut 3 engage with the plug threads of the plug and are tightened, the bulkhead is trapped between the fixing nut 3 and the annular lip of the plug body 1.

[0053] The socket of the plug assembly only needs to be connected to the plug. For example, the first extension 101 of the plug body 1 is inserted into the second predetermined space 202 of the socket. At this point, the metal needle tube 203 is connected to the metal pin 103 in a one-to-one correspondence, enabling electrical signal transmission. As the annular nut threads engage with the plug threads of the plug, the first extension 101 of the plug body 1 contacts and compresses the socket sealing ring 5 within the second predetermined space 202, preventing water from seeping into the plug assembly.

[0054] To further enhance waterproofing, the waterproof motor compartment also includes a sealant that seals at least a portion of the second extension 102. For example, the sealant is applied to the end corresponding to the second extension 102. The sealant seals the contact between the second extension 102 and the inner wall of the waterproof motor compartment, thereby preventing water from entering the waterproof motor compartment along the plug assembly. The sealant application step can be performed after installing the plug and socket, or after installing the plug and before installing the socket.

[0055] In the embodiment of the present application, the plug-in combination of the plug and socket simplifies installation and reduces maintenance difficulty. The sealing ring 4 prevents water from entering the waterproof motor compartment. The sealant further improves the waterproof performance, ensures the waterproof effect of the waterproof motor compartment, and ensures connection reliability.
