Abstract
Description
Technical Field
[0001] This application relates to the field of panel switch technology, and in particular to a switch base and a panel switch. Background Technology
[0002] Panel switches are electrical devices used to disconnect or connect current to one or more circuits, and are often used in home environments to control lighting fixtures.
[0003] After installation, there is a certain gap between the panel switch and the mounting surface (such as a wall). In humid environments (such as during the spring season) or when the user operates the panel switch with wet hands, water can flow along the mounting surface and enter the switch base through the heat dissipation holes or terminal holes on the upper wall of the switch base. This can easily cause corrosion and damage to the circuit components such as the circuit board inside the switch base, resulting in internal circuit failure of the panel switch and affecting user operation. Summary of the Invention
[0004] This application provides a switch base and a panel switch, the purpose of which is to improve the waterproof performance of the switch base.
[0005] To achieve the above objectives, this application adopts the following technical solution:
[0006] In a first aspect, a switch base is provided, comprising: a housing and a frame, the housing having a receiving cavity with an opening; the frame being disposed on the outer periphery of the housing near the opening; the housing having a hole on a first surface of the housing and communicating with the receiving cavity; a guide groove being disposed on the first surface, and at least one edge of the guide groove extending to a second surface of the housing, the second surface being connected to the first surface.
[0007] In some usage scenarios, liquid may enter the interior of a switch base through holes. The switch base described in this application has a guide channel on the surface where the hole is located (e.g., the first surface). Liquid on the first surface can enter the guide channel and flow along it to the edge. In other words, liquid on the first surface can flow through the guide channel to the second surface connected to the first surface, thus guiding the liquid on the surface where the hole is located. This prevents liquid on the first surface from entering the housing cavity through holes (e.g., terminal holes, heat dissipation holes, etc.) and damaging components (e.g., circuit boards) within the housing, thereby improving the safety performance of the switch base. Therefore, the solution provided in this application can prevent liquid from entering the housing of the switch base, improving its waterproof and safety performance.
[0008] In one feasible implementation, the flow channel is closer to the edge than the hole.
[0009] In some application scenarios, the side of the switch base housing away from the frame may be embedded in the mounting surface. In this case, the side of the frame away from the opening of the housing is closer to the mounting surface than the side of the housing away from the opening. As a result, the guide channel is closer to the frame than the hole. This allows liquid on the mounting surface to flow into the guide channel, which is closer to the frame, before flowing onto the switch base housing, instead of flowing directly into the hole. This further reduces the risk of liquid entering the housing cavity from the hole, ensuring the safety of the switch base.
[0010] In one feasible implementation, the flow channel includes a first flow channel, the first flow channel including an inclined first flow surface, the first flow surface extending in a direction away from the opening of the first flow channel from the center of the first flow channel to the edge of the first flow channel facing the second surface.
[0011] By tilting the first guide surface of the first guide groove, the liquid in the first guide groove can flow quickly from the first surface to the second surface. The liquid in the first guide groove can flow from the center of the first guide groove to the edge of the first guide groove facing the second surface on the first guide surface, and then flow from the first surface to the second surface, thus avoiding the accumulation of liquid in the first guide groove and the situation where the liquid in the first surface enters the hole of the first surface.
[0012] In one feasible implementation, the second surface is connected to the border.
[0013] In some scenarios, the second side of the housing opposite to the frame may have a connection hole (such as a wiring hole) or an electrical component that communicates with the receiving cavity. If liquid flows to this second side, it may enter the receiving cavity from the second side or damage the electrical component on the second side. By guiding the liquid from the first side to the second side connected to the frame, the situation of liquid flowing into the second side and then into the receiving cavity of the housing or damaging the electrical component on the second side can be avoided.
[0014] In another possible implementation, the second surface is located on the side of the housing away from the frame.
[0015] In some scenarios, the second surface of the housing connected to the frame may have a connection hole (such as a wiring hole) or an electrical component that communicates with the receiving cavity. If liquid flows to the second surface, it may enter the receiving cavity from the second surface or damage the electrical component on the second surface. By guiding the liquid from the first surface to the second surface connected to the frame, the situation of liquid flowing into the second surface and then into the receiving cavity of the housing or damaging the electrical component on the second surface can be avoided.
[0016] In one possible implementation, the second surface comprises two opposing sides, and the first guide groove has opposing first edges and second edges, the first edge extending to one of the opposing second surfaces and the second edge extending to the other of the opposing second surfaces.
[0017] In this embodiment, the liquid in the first guide channel can flow from the opposite first edge and the second edge to the opposite two second surfaces, thereby guiding the liquid in the first guide channel to the opposite two second surfaces.
[0018] In one feasible implementation, the first guide groove extends at one end toward the frame to the junction of the first surface and the frame.
[0019] This allows liquid flowing from the side of the frame away from the opening to flow directly into the first guide groove and out along the first guide groove, further improving the waterproof performance of the switch base.
[0020] In another possible implementation, the flow channel further includes at least one second flow channel, which is closer to the frame than the first flow channel; the second flow channel communicates with the first flow channel at the end away from the frame, and the second flow channel extends to the connection between the first surface and the frame at the end facing the frame.
[0021] In this embodiment, liquid flowing into the first surface from the side opposite to the opening of the frame flows into the second guide groove, then into the first guide groove and flows out of the first surface along the first guide groove. The second guide groove can prevent liquid flowing into the first surface from the side opposite to the opening of the frame from entering the receiving cavity inside the housing, and can also ensure the connection strength between the housing (e.g., the first surface of the housing) and the frame.
[0022] In one feasible implementation, the width of the second guide channel is smaller than the width of the first guide channel.
[0023] In some application scenarios, the liquid flowing into the first surface originates from the mounting surface of the switch base, and secondly from the side of the frame away from the opening. Based on this, the size and layout of the guide channel should be reasonably set, that is, the width of the second guide channel should be set to be smaller than the width of the first guide channel. While draining the liquid from the first surface, the strength of the housing and the connection strength between the housing (such as the first surface of the housing) and the frame should be guaranteed.
[0024] In one feasible implementation, the second guide channel includes an inclined second guide surface; the second guide surface extends toward the groove opening away from the first surface from the connection between the first surface and the housing to the edge of the second guide channel away from the frame.
[0025] By tilting the second guide surface of the second guide channel, the liquid can flow quickly from the second guide surface to the first guide surface. Specifically, the liquid can flow from the connection between the first surface and the housing on the second guide surface toward the edge of the second guide channel away from the frame, and then flow into the first guide channel and out of the first surface along the first guide channel.
[0026] In one feasible implementation, the second guide channel includes a plurality of channels, which are spaced apart between two opposing second surfaces.
[0027] Since multiple second guide channels are spaced apart between two opposite second surfaces, this ensures that the liquid flowing from the frame into the first surface flows into the second guide channels as much as possible. In addition, it can further improve the strength of the shell itself and the connection strength between the shell (such as the first surface of the shell) and the frame.
[0028] In one feasible implementation, a water-blocking element is provided on the outer periphery of the hole, and the water-blocking element protrudes from the first surface.
[0029] Since the water-blocking component protrudes from the first surface, the water-blocking component set on the outer periphery of the hole can prevent water from the first surface from entering the hole. In other words, it prevents liquid from the first surface from entering the receiving cavity inside the housing through the hole, thereby further improving the waterproof performance of the switch base.
[0030] In one feasible implementation, the holes include at least two holes that share a single water-blocking element.
[0031] In this embodiment, by having at least two holes share a single water-blocking element, the cost and weight of the switch base can be reduced.
[0032] In one feasible implementation, the water-blocking element includes a water-blocking ring disposed around the outer periphery of the hole.
[0033] In this embodiment, liquid flowing into the outer periphery of the hole from the first surface can be blocked by the water-blocking ring to prevent liquid from entering the hole from the first surface.
[0034] In one feasible implementation, the water-blocking component is integrally formed with the housing.
[0035] This reduces both the processing steps and costs of the switch base, and also reduces the assembly steps.
[0036] In one feasible implementation, the second surface is provided with a first hole, which communicates with the receiving cavity, and a first water-blocking member is provided on the outer periphery of the first hole, which protrudes from the second surface.
[0037] In this way, the first water-blocking component set on the outer periphery of the first hole can prevent water from the second side from entering the first hole, that is, to prevent liquid from the second side from entering the receiving cavity inside the housing through the first hole, so as to further improve the waterproof performance of the switch base.
[0038] In one feasible implementation, the first hole includes at least two, and the at least two first holes share a first water-blocking element.
[0039] This reduces the cost and weight of the switch base.
[0040] In one feasible implementation, the first water-blocking member includes a first water-blocking ring, which is disposed around the outer periphery of the first hole.
[0041] In this embodiment, liquid flowing into the outer periphery of the second surface toward the first hole can be blocked by the first water-blocking ring to prevent liquid from the second surface from entering the first hole.
[0042] In one feasible implementation, the first water-blocking component is integrally formed with the housing.
[0043] This reduces both the processing steps and costs of the switch base housing, and also reduces the assembly steps.
[0044] In one possible implementation, the switch base further includes a seal disposed on the side of the frame away from the opening and circumferentially surrounding the housing.
[0045] Because a gap exists between the side of the frame away from the opening and the mounting surface after the switch base is installed, this seal can create a seal between the frame and the mounting surface after the switch base is assembled onto the mounting surface. This prevents liquid from flowing from the gap between the frame and the mounting surface onto the switch base housing, that is, it prevents liquid from flowing from the switch base housing into the receiving cavity inside the housing. Therefore, the seal further improves the waterproof performance of the switch base.
[0046] In one feasible implementation, the seal includes waterproof foam.
[0047] During assembly, the waterproof foam can prevent liquid from flowing from the gap between the frame and the mounting surface to the housing of the switch base. On the other hand, it can reduce the gap between the frame and the mounting surface through its own compression deformation, ensuring the installation of the switch base while improving the appearance of the switch base after installation.
[0048] In another possible implementation, the sealant includes a sealant.
[0049] This sealant is used to prevent liquid from flowing from the gap between the frame and the mounting surface onto the switch base housing and to reduce the gap between the frame and the mounting surface.
[0050] A second aspect of this application provides a panel switch, such as a socket switch, rocker switch, touch switch, rotary switch, inductive switch, etc.
[0051] The panel switch includes the aforementioned switch base and panel, with the panel mounted on the switch base.
[0052] The panel switch provided in this application includes the switch base described above. Therefore, the panel switch provided in this application and the switch base of the above-described technical solution can solve the same technical problem and have the same technical effect, which will not be repeated here.
[0053] A third aspect of this application provides a switch base housing, for example, for the switch base described above or the panel switch described above.
[0054] The switch base housing includes: a housing and a frame, the housing having a receiving cavity with an opening; the frame being disposed on the outer periphery of the housing near the opening; the housing having a hole on a first surface of the housing and communicating with the receiving cavity; a guide groove being disposed on the first surface, and at least one edge of the guide groove extending to a second surface of the housing connected to the first surface.
[0055] In some usage scenarios, liquid may enter the interior of the switch base housing along the holes. In the switch base housing provided in this application, a guide channel is provided on the surface where the hole is located (e.g., the first surface). Liquid on the first surface can enter the guide channel and flow to its edge. In other words, liquid on the first surface can flow through the guide channel to the second surface connected to the first surface, achieving a guiding effect on the surface where the hole is located. This prevents liquid on the first surface of the housing from entering the housing cavity through the holes (e.g., terminal holes, heat dissipation holes, etc.) and damaging components (e.g., circuit boards, etc.) within the housing, thus improving the safety performance of the switch base. Therefore, the solution provided in this application can prevent liquid from entering the housing cavity of the switch base, improving the waterproof and safety performance of the switch base.
[0056] In one feasible implementation, the flow channel is closer to the edge than the hole.
[0057] In some application scenarios, the side of the switch base housing away from the frame may be embedded in the mounting surface. In this case, the side of the frame away from the opening of the housing is closer to the mounting surface than the side of the housing away from the opening. As a result, the guide channel is closer to the frame than the hole. This allows liquid on the mounting surface to flow into the guide channel, which is closer to the frame, before flowing onto the switch base housing, instead of flowing directly into the hole. This further reduces the risk of liquid entering the housing cavity from the hole and ensures the safety of the switch base.
[0058] In one feasible implementation, the flow channel includes a first flow channel, the first flow channel including an inclined first flow surface, the first flow surface extending in a direction away from the opening of the first flow channel from the center of the first flow channel to the edge of the first flow channel facing the second surface.
[0059] By tilting the first guide surface of the first guide channel, it is easier for liquid to flow from the first surface to the second surface. Specifically, the liquid can flow from the center of the first guide channel to the edge of the first guide channel facing the second surface on the first guide surface, and then flow out from the first surface.
[0060] In one feasible implementation, the second surface is connected to the border.
[0061] In some scenarios, the second side of the housing opposite to the frame may have a connection hole (such as a wiring hole) or an electrical component that communicates with the receiving cavity. If liquid flows to this second side, it may enter the receiving cavity from the second side or damage the electrical component on the second side. By guiding the liquid from the first side to the second side connected to the frame, the situation of liquid flowing into the second side and then into the receiving cavity of the housing or damaging the electrical component on the second side can be avoided.
[0062] In another possible implementation, the second surface is located on the side of the housing away from the frame.
[0063] In some scenarios, the second surface of the housing connected to the frame may have a connection hole (such as a wiring hole) or an electrical component that communicates with the receiving cavity. If liquid flows to the second surface, it may enter the receiving cavity from the second surface or damage the electrical component on the second surface. By guiding the liquid from the first surface to the second surface connected to the frame, the situation of liquid flowing into the second surface and then into the receiving cavity of the housing or damaging the electrical component on the second surface can be avoided.
[0064] In one possible implementation, the second surface comprises two opposing sides, and the first guide groove has opposing first edges and second edges, the first edge extending to one of the opposing second surfaces and the second edge extending to the other of the opposing second surfaces.
[0065] In this embodiment, the liquid in the first guide channel can flow from the opposite first edge and the second edge to the opposite two second surfaces, thereby guiding the liquid in the first guide channel to the opposite two second surfaces.
[0066] In one feasible implementation, the first guide groove extends at one end toward the frame to the junction of the first surface and the frame.
[0067] This allows liquid flowing from the side of the frame away from the opening to flow directly into the first guide groove and out along the first guide groove, further improving the waterproof performance of the switch base housing.
[0068] In another possible implementation, the flow channel further includes at least one second flow channel, which is closer to the frame than the first flow channel; the second flow channel communicates with the first flow channel at the end away from the frame, and the second flow channel extends to the connection between the first surface and the frame at the end facing the frame.
[0069] In this embodiment, liquid flowing into the first surface from the side opposite to the opening of the frame flows into the second guide groove, then into the first guide groove and flows out of the first surface along the first guide groove. The second guide groove can prevent liquid flowing into the first surface from the side opposite to the opening of the frame from entering the receiving cavity inside the housing, and can also ensure the connection strength between the housing (e.g., the first surface of the housing) and the frame.
[0070] In one feasible implementation, the width of the second guide channel is smaller than the width of the first guide channel.
[0071] In some usage scenarios, the liquid flowing into the first surface mainly comes from the mounting surface of the panel switch, and secondly from the side of the frame away from the opening. Based on this, the size and layout of the guide channel should be reasonably set, that is, the width of the second guide channel should be set to be smaller than the width of the first guide channel. While draining the liquid from the first surface, the strength of the housing and the connection strength between the housing (such as the first surface of the housing) and the frame should be guaranteed.
[0072] In one feasible implementation, the second guide channel includes an inclined second guide surface; the second guide surface extends toward the groove opening away from the first surface from the connection between the first surface and the housing to the edge of the second guide channel away from the frame.
[0073] By tilting the second guide surface of the second guide channel, it is easier for liquid to flow from the second guide surface to the first guide surface. Specifically, the liquid can flow from the connection between the first surface and the housing on the second guide surface toward the edge of the second guide channel away from the frame, and then flow into the first guide channel and out of the first surface along the first guide channel.
[0074] In one feasible implementation, the second guide channel includes a plurality of channels, which are spaced apart between two opposing second surfaces.
[0075] Since multiple second guide channels are spaced apart between two opposite second surfaces, this ensures that the liquid flowing from the frame into the first surface flows into the second guide channels as much as possible. In addition, it can further improve the strength of the shell itself and the connection strength between the shell (such as the first surface of the shell) and the frame.
[0076] In one feasible implementation, a water-blocking element is provided on the outer periphery of the hole, and the water-blocking element protrudes from the first surface.
[0077] Since the water-blocking component protrudes from the first surface, the water-blocking component set on the outer periphery of the hole can prevent water from the first surface from entering the terminal hole. In other words, it prevents liquid from the first surface from entering the receiving cavity inside the housing through the hole, thereby further improving the waterproof performance of the switch base housing.
[0078] In one feasible implementation, the holes include at least two holes that share a single water-blocking element.
[0079] In this embodiment, by having at least two holes share a single water-blocking element, the cost and weight of the switch base housing can be reduced.
[0080] In one feasible implementation, the water-blocking element includes a water-blocking ring disposed around the outer periphery of the hole.
[0081] In this embodiment, liquid flowing into the outer periphery of the hole can be blocked by the water-blocking ring to prevent liquid from the first side from entering the hole.
[0082] In one feasible implementation, the water-blocking component is integrally formed with the housing.
[0083] This reduces both the processing steps and costs of the switch base housing, and also reduces the assembly steps.
[0084] In one feasible implementation, the second surface is provided with a first hole, which communicates with the receiving cavity, and a first water-blocking member is provided on the outer periphery of the first hole, which protrudes from the second surface.

[0086] In one feasible implementation, the first hole includes at least two, and the at least two first holes share a first water-blocking element.
[0087] This reduces the cost and weight of the switch base housing.
[0088] In one feasible implementation, the first water-blocking member includes a first water-blocking ring, which is disposed around the outer periphery of the first hole.
[0089] In this embodiment, liquid flowing into the outer periphery of the second surface toward the first hole can be blocked by the first water-blocking ring to prevent liquid from the second surface from entering the first hole.
[0090] In one feasible implementation, the first water-blocking component is integrally formed with the housing.
[0091] This reduces both the processing steps and costs of the switch base housing, and also reduces the assembly steps. Attached Figure Description

[0106] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0107] This application provides a panel switch 100, which can be a socket switch, rocker switch, touch switch, rotary switch, induction switch, etc. This application does not impose any special restrictions on the specific form of the panel switch 100.
[0108] Figure 1 A schematic diagram of a panel switch is provided as an example. The panel switch 100 includes a panel 20 and a switch base 10, with the panel 20 mounted on the switch base 10.
[0109] Figure 2 An illustrative diagram illustrating a use case for a panel switch is provided. For example... Figure 2 The panel switch 100 is installed on the mounting surface 200. The side of the panel 20 that is away from the panel operation surface (i.e. the user's visible surface) faces the mounting surface 200. The side of the switch base 10 that is away from the panel 20 is embedded in the mounting surface 200.
[0110] Panel 20 can be installed on switch base 10 in any suitable manner. For example, panel 20 can be detachably installed on switch base 10 by means of snap-fit connection, adhesive, plug-in, etc., which facilitates the user's installation of panel switch 100 and the maintenance and replacement of panel 20 and switch base 10. This application embodiment does not impose any special restrictions on the specific connection method between panel 20 and switch base 10.
[0111] Figure 3 An exploded view of the panel and switch base in a panel switch is provided as an example. Figure 3A latch is provided on the side of panel 20 opposite to the operating surface (i.e., the user-visible surface), and a slot is provided on switch base 10. The latch and slot cooperate to connect panel 20 and switch base 10. Alternatively, panel 20 can be electrically connected to switch base 10 in any other way. For example, a plug is provided on the side of panel 20 opposite to the operating surface, and a socket is provided on switch base 10. The plug and socket are inserted into each other to achieve electrical connection between panel 20 and switch base 10.
[0112] Figure 4 A schematic diagram of a switch base 10 is provided as an example. The switch base 10 can be a switch base for a socket switch, rocker switch, touch switch, rotary switch, inductive switch, etc., and the embodiments of this application do not impose any limitations on it.
[0113] Figure 5 An exploded view of a switch base 10 is provided as an example. Figure 2 , Figure 4 and Figure 5 The switch base 10 may include a switch base housing 101, a circuit component 102, and a cover plate 103. The switch base housing 101 may include a housing 11 and a frame 12. The frame 12 is disposed on the outer periphery of the housing 11 facing the panel 20. The end of the housing 11 away from the frame 12 is embedded in the mounting surface 200. The side of the frame 12 that is away from the panel operation surface (i.e. the user-visible surface) of the panel 20 faces the mounting surface 200.
[0114] Figure 6 An exemplary structural schematic diagram of a switch base housing is provided. For example... Figure 6 The housing 11 has a receiving cavity 111, the receiving cavity 111 has an opening 1111, and a frame 12 is disposed on the outer periphery of the housing 11 near the opening 1111. Figures 4 to 6 The circuit component 102 can be installed inside the receiving cavity 111, and the cover plate 103 is installed on the side of the switch base housing 101 where the opening 1111 is provided, to block the opening 1111.
[0115] This application does not impose any special restrictions on the structure, circuit layout, and connection method of the circuit component 102. For example, the circuit component 102 may include structures such as circuit boards, relays, and relay boards, and those skilled in the art can selectively design them according to actual needs.
[0116] like Figure 2 , Figure 4 and Figure 6When the switch base 10 is installed, the side of the housing 11 of the switch base 10 facing away from the frame 12 is embedded in the mounting surface 200. The side of the frame 12 facing away from the opening 1111 faces the mounting surface 200, and there is a gap between the side of the frame 12 away from the opening 1111 and the mounting surface 200. To prevent liquid from entering the receiving cavity 111 inside the switch base housing 101 through this gap and damaging the circuit components 102, in some examples, such as Figure 2 , Figures 4 to 6 The switch base 10 may also include a seal 104, which is disposed on the side of the frame 12 away from the opening 1111 and circumferentially surrounding the housing 11. This seal 104 establishes a seal between the frame 12 and the mounting surface 200, thereby preventing liquid from flowing from the gap between the frame 12 and the mounting surface 200 onto the switch base housing 101. In other words, it prevents liquid from flowing from the housing 11 of the switch base housing 101 into the receiving cavity 111 within the housing 11, thus ensuring the safe operation of the circuit components 102 within the receiving cavity 111.
[0117] In some examples, the seal 104 may include waterproof foam. During assembly, the waterproof foam's own waterproof properties can prevent liquid from flowing from the gap onto the switch base housing 101, and the waterproof foam can also reduce the gap between the frame 12 and the mounting surface 200 through its own compression deformation. This ensures the installation of the switch base 10 while improving the aesthetic appearance of the installed switch base 10.
[0118] Alternatively, in some other examples, seal 104 may include sealant. After the sealant is applied to the side of frame 12 away from opening 1111, the gradually solidifying sealant can create a seal between mounting surface 200 and frame 12 after the switch base 10 is installed. This prevents liquid from flowing from the gap between frame 12 and mounting surface 200 onto switch base housing 101. At the same time, it can also reduce the gap between frame 12 and mounting surface 200, improving the aesthetic appearance of the switch base 10 after installation.
[0119] In some examples, the liquid mentioned above can be water or other liquids, and this application makes no restrictions on this.
[0120] Figure 7 An exemplary structural schematic diagram of a switch base housing from another angle is provided. For example... Figure 6 and Figure 7 The housing 11 of the switch base housing 101 may have a hole 112, a first surface 113 and a second surface 114. The hole 112 is opened on the first surface 113 of the housing 11 and communicates with the receiving cavity 111.
[0121] In some examples, hole 112 may include a terminal hole. Alternatively, in other examples, hole 112 may include holes for other purposes, such as heat dissipation holes, wiring holes, etc. This application embodiment does not impose special limitations on the number and shape of holes 112. For example, there may be one or multiple holes 112, and holes 112 may be circular holes or rectangular holes, etc.
[0122] like Figure 7 In this example, hole 112 includes two terminal holes, both of which are round holes.
[0123] In some examples, the first surface 113 can be any surface of the housing 11, and the second surface 114 is the surface connected to the first surface 113, for example, such as Figure 7 The first surface 113 is the upper surface of the housing 11 in the installed state. Figure 7 As shown above and below), the second surface 114 may include the left side of the housing 11 in the installed state (i.e., the side of the housing 11 corresponding to the user's left hand when the user is facing the opening 1111, such as...). Figure 7 The left and right sides shown (i.e., the side of the housing 11 corresponding to the user's right hand when the user is facing the opening 1111, as shown) Figure 7 (as shown on the right side), one or more of the surfaces of the housing 11 facing away from the frame 12, for example, as Figure 7 The second surface 114 of the housing 11 is the left and right side of the housing 11 in the installed state.
[0124] To prevent liquid from flowing into the receiving cavity 111 inside the housing 11 from the hole 112 on the first surface 113, in some examples, a flow channel can be provided on the first surface 113, and at least one edge of the flow channel can extend to the second surface 114 of the housing 11. In this way, the liquid on the first surface 113 can flow to the second surface 114 through the flow channel, thereby achieving the flow of liquid on the first surface 113.
[0125] In some examples, such as Figure 7 The flow channel is closer to the frame 12 than the hole 112. For example... Figure 2 , Figure 6 and Figure 7 After the panel switch 100 is installed, the side of the frame 12 facing away from the opening 1111 of the housing 11 is closer to the mounting surface 200 than the side of the housing 11 facing away from the opening 1111. Therefore, by making the guide groove closer to the frame 12 than the hole 112, when the liquid on the mounting surface 200 flows to the housing 11, it first flows to the guide groove which is closer to the frame 12, instead of flowing directly into the hole 112. This further reduces the risk of liquid entering the receiving cavity 111 inside the housing 11 from the hole 112, and ensures the safety of the switch base 10.
[0126] like Figure 7 In this example, the second face 114 includes the oppositely positioned left face ( Figure 7 The left and right sides shown in the diagram Figure 7 As shown on the right side), the flow channel includes a first flow channel 115. The first flow channel 115 has a first edge 1151 and a second edge 1152 disposed opposite to each other. The first edge 1151 extends to the left side of the housing 11, and the second edge 1152 extends to the right side of the housing 11. The liquid in the first flow channel 115 can flow from the opposite first edge 1151 and the second edge 1152 to the left side and the right side of the housing 11, respectively. That is, the liquid on the upper surface of the housing 11 is guided to the left side and the right side of the housing 11.
[0127] In some examples, the first guide channel 115 may include an inclined first guide surface 1153, extending from the center of the first guide channel 115 to the edge of the first guide channel 115 toward the second surface 114 (e.g., Figure 7 In the directions A1 and A2 shown, the first guide surface 1153 extends toward the direction away from the opening of the first guide groove 115. The inclined first guide surface 1153 allows the liquid flowing into the first guide groove 115 to flow quickly to the edge of the first guide groove 115 facing the second surface 114, and then flow from the first surface 113 to the second surface 114, avoiding the accumulation of liquid in the first guide groove 115 and the situation where the liquid in the first surface 113 enters the hole 112 of the first surface 113.
[0128] like Figure 7 In this example, the first guide surface 1153 extends from the center of the first guide groove 115 to the first edge 1151 (i.e., Figure 7 The direction A1 shown extends in the direction away from the opening of the first guide channel 115, and the first guide channel 115 extends from the center of the first guide channel 115 to the second edge 1152 (i.e., Figure 7 The direction A2 shown extends away from the opening of the first guide channel 115. This can be understood as the first guide surface 1153 being higher in the middle and lower on the left and right (i.e., when the user is facing the opening 1111, the left side corresponds to the user's left hand, and the right side corresponds to the user's right hand). Figure 7 (as shown in the left and right diagrams), thereby facilitating the flow of liquid from the first guide channel 115 to the second surface 114.
[0129] The tilt angle of the first guide surface 1153 can be selectively designed according to actual needs, and this application does not impose any special restrictions on it.
[0130] In some examples, the first guide groove 115 can extend to the connection between the first surface 113 and the frame 12 at one end facing the frame 12. In this way, liquid flowing into the first surface 113 from the side of the frame 12 away from the outlet 1111 can flow directly into the first guide groove and flow out along the first guide groove, further improving the waterproof performance of the switch base 10.
[0131] Alternatively, in other examples, the flow channel may also include at least one second flow channel 116, which is closer to the frame 12 than the first flow channel 115; the second flow channel 116 communicates with the first flow channel 115 at the end opposite to the frame 12, and the second flow channel 116 extends to the junction of the first surface 113 and the frame 12 at the end facing the frame 12.
[0132] This can be understood as follows: the liquid flowing into the first surface 113 from the side of the frame 12 away from the opening 1111 first flows into the second guide groove, then merges into the first guide groove and flows out of the first surface 113 along the first guide groove. The second guide groove can prevent the liquid flowing into the first surface 113 from the side of the frame 12 away from the opening 1111 from entering the receiving cavity 111 inside the housing 11, and can also ensure the connection strength between the housing 11 and the frame 12.
[0133] Since the liquid flowing into the first surface 113 originates from the mounting surface 200 of the switch base 10, and secondly from the side of the frame 12 opposite to the opening 1111, in other words, the amount of liquid flowing in from the side of the frame 12 opposite to the opening 1111 is relatively small. Therefore, as Figure 7 The width of the second guide channel 116 is set to be smaller than that of the first guide channel 115, which can further ensure the strength of the shell 11 and the connection strength between the shell 11 and the frame 12 while draining the liquid on the first surface 113.
[0134] like Figure 7 The second guide channel 116 may further include an inclined second guide surface 1161; the direction from the connection between the first surface 113 and the housing 11 to the edge of the second guide channel 116 away from the frame 12 ( Figure 7 In the direction shown (B direction), the second guide surface 1161 extends toward the direction away from the opening of the second guide groove 116. It can be understood that the edge of the second guide groove 116 away from the frame 12 is lower than the side facing the frame 12. Therefore, the inclined second guide surface 1161 allows the liquid flowing into the second guide groove 116 to flow quickly to the first guide groove 115 and then flow out from the first guide groove 115.
[0135] The tilt angle of the second guide surface 1161 can be selectively designed according to actual needs, and this application does not impose any special restrictions on it.
[0136] In some switch base housings 101, such as Figure 7 The second guide channel 116 may include multiple channels, which are spaced apart between two opposite second surfaces 114 to ensure that the liquid flowing from the frame 12 into the first surface 113 flows into the second guide channel 116 as much as possible. In addition, it can further improve the strength of the housing 11 itself and the connection strength between the housing 11 and the frame 12.
[0137] To further improve the waterproof performance of the switch base housing 101, in some examples, such as Figure 7 A water-blocking element is provided on the outer periphery of the hole 112. The water-blocking element protrudes from the first surface 113. The water-blocking element can prevent water from the first surface 113 from entering the hole 112, that is, prevent the liquid on the first surface 113 from entering the receiving cavity 111 inside the housing 11 through the hole 112.
[0138] In some examples, the holes 112 may include at least two holes 112 that share a single water-blocking element. In these examples, by having at least two holes 112 share a single water-blocking element, the cost and weight of the switch base housing 101 can be reduced.
[0139] like Figure 7 In this example, the water-blocking component may include a water-blocking ring 117, which is arranged around the outer periphery of the hole 112. This allows liquid flowing into the hole 112 from any direction toward the outer periphery of the hole 112 to be blocked by the water-blocking ring 117, thereby preventing liquid from the first surface 113 from entering the hole 112.
[0140] In some other examples, the second surface 114 is provided with a first hole, which communicates with the receiving cavity 111. A first water-blocking member is provided on the outer periphery of the first hole, and the first water-blocking member protrudes from the second surface 114. The first water-blocking member can prevent water from the second surface 114 from entering the first hole, that is, prevent liquid from the second surface 114 from entering the receiving cavity 111 inside the housing 11 through the first hole.
[0141] In this example, the first hole includes at least two holes that share a first water-blocking element to reduce the cost and weight of the switch base 10.
[0142] The first water-blocking component may also include a first water-blocking ring. The first water-blocking component is arranged around the outer periphery of the first hole. In this example, liquid flowing into the second surface 114 toward the outer periphery of the first hole can be blocked by the first water-blocking ring to prevent liquid from the second surface 114 from entering the first hole.
[0143] In some examples, the water baffle is integrally formed with the housing 11. This reduces the number of processing steps for the switch base 10 and lowers processing costs, and also reduces the number of assembly steps for the switch base 10.
[0144] In some examples, the first water-blocking component is integrally formed with the housing 11. This reduces the number of processing steps for the switch base 10, thereby lowering processing costs, and also reduces the number of assembly steps for the switch base 10.
[0145] In some examples, the switch base housing 101 is a one-piece molded part, which is convenient for processing and manufacturing.
