Description

Technical Field

[0001] This utility model relates to the field of smart socket technology, and in particular to an adapter and its adapter base. Background Technology

[0002] Track sockets are a new type of power socket product, mainly consisting of a power track and an adapter socket. Track sockets are divided into surface-mounted and recessed types. Surface-mounted sockets have the power track attached to the wall, and the adapter socket is then connected to the power track. This is suitable for situations where installation grooves were not pre-reserved during home renovation. Recessed sockets have the power track installed inside the wall, so that the adapter socket is located within the wall surface, resulting in a smooth, aesthetically pleasing surface and high safety.

[0003] Currently, adapter sockets in existing technology can usually only be used for surface-mounted tracks. When used for recessed tracks, the power supply port of the socket is located inside the wall and is covered by the wall, making the power supply port unusable and greatly reducing the practicality of the track socket. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the present invention provides an adapter and its adapter base, which can be adapted to both surface-mounted and concealed tracks.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adapter base includes a main frame and a circuit board assembly. The main frame has an installation space inside. The main frame includes a first side and a second side with different extending directions. The first side has a first power port communicating with the installation space, and the second side has a second power port communicating with the installation space.

[0010] In one embodiment, the first side is parallel to the length direction of the main frame, and the second side is parallel to the width direction of the main frame; the IoT adapter base also includes a plug, which is disposed in the installation space and connected to the main frame, and the plug has a through hole; wherein, the second connection terminal is connected to the second power port through the through hole.

[0011] In one embodiment, the adapter base further includes a power receiving part connected to the main frame. One end of the power receiving part is connected to the circuit board assembly, and the other end extends out of the main frame to be electrically connected to an external power source.

[0012] In one embodiment, the main frame includes an outer shell, a bottom cover, and a buckle. The bottom cover is connected to the outer shell, and the bottom cover and the outer shell enclose the installation space. The buckle is connected to the bottom cover and is used to engage with an external power source.

[0013] In one embodiment, the adapter base further includes an adapter for connecting an external product and for adjusting the connection angle of the external product.

[0014] This utility model also adopts another technical solution: a transfer device, including a track and a transfer base as described in any of the above embodiments, the track including a guide rail and a conductive sheet, the main frame in the transfer base being movably connected to the guide rail, and the conductive sheet being electrically connected to the circuit board assembly in the transfer base.

[0015] In one embodiment, the first side is parallel to the extension direction of the guide rail, and the second side is perpendicular to the extension direction of the guide rail.

[0016] In one embodiment, the guide rail includes a bottom and side portions symmetrically arranged on both sides of the bottom. The side portions and the bottom enclose a receiving space. When the adapter base is connected to the rail, the side portions cover the first power port and the second power port is located within the receiving space; or, both the first power port and the second power port are located outside the receiving space.

[0017] The beneficial effects of this utility model are as follows: This application provides an adapter device, including an adapter base and a track, with the adapter base connected to the track. The adapter base includes a main frame and a circuit board assembly. An installation space is provided inside the main frame, and the circuit board assembly is disposed within the installation space.

This adapter base is compatible with both surface-mounted and recessed tracks, greatly improving its practicality. The adapter device using this adapter base is suitable for various home environments, providing users with more installation options. Attached Figure Description

Therefore, they should not be construed as limitations on this application.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] Furthermore, in addition to indicating direction or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this utility model according to the specific circumstances.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0034] See Figure 1 This application provides an adapter device, including an adapter base 20 and a track 10. The adapter base 20 is connected to the track 10, and the track 10 is connected to an external power source to provide power to the adapter base 20. The adapter base 20 is used to electrically connect to an external product 30 for charging the external product 30.

[0035] It should be noted that the adapter base 20 is a power socket with power supply or network connection functions. In addition to charging the external product 30, the adapter base 20 also has mounting holes for installing the external product 30. Specifically, the mounting holes are usually opened on the side of the adapter base 20 away from the rail 10. The mounting holes and the rail 10 are located on opposite sides of the adapter base 20 to facilitate the installation of the external product 30.

[0036] In one embodiment, the adapter base 20 includes a main frame 201 and a circuit board assembly 204. The main frame 201 has an installation space 2016 inside, and the circuit board assembly 204 is disposed in the installation space 2016. The main frame 201 includes a first side 2014 and a second side 2015 with different extending directions. The first side 2014 has a first power port 2017 communicating with the installation space 2016, and the second side 2015 has a second power port 2018 communicating with the installation space 2016. The external product 30 extends into the installation space 2016 from the first power port 2017 and the second power port 2018 and is electrically connected to the circuit board assembly 204.

[0037] It should be noted that the track 10 is divided into surface-mounted track and concealed track. The surface-mounted track is mounted against the wall, with the track 10 protruding from the wall surface. The adapter base 20 is then connected to the track 10, as shown below. Figure 1 As shown, this method allows the adapter base 20 to be fully exposed in the wall, facilitating the connection of the external product 30; concealed track refers to having a certain length of mounting groove cut into the wall, installing the track 10 in the mounting groove, with the track 10 located inside the wall, and then connecting the adapter base 20 to the track 10, as shown. Figure 2 As shown, this method allows the adapter base 20 to be located entirely within the wall, with its bottom side flush with the wall surface, resulting in a high level of aesthetics and safety.

[0038] In order to make this application compatible with both surface-mounted and concealed tracks, the first side 2014 and the second side 2015 of the adapter base 20 are respectively provided with a first power port 2017 and a second power port 2018. Since the first side 2014 and the second side 2015 extend in different directions, the plane where the first side 2014 is located and the plane where the second side 2015 is located are set at an angle. For example, the extension direction of the first side 2014 can be consistent with the length direction of the track 10, while the extension direction of the second side 2015 is inconsistent with the length direction of the track 10. In this way, when the adapter base 20 is installed in the concealed track, the first side 2014 is blocked by the groove wall (or wall) of the mounting groove, while the second side 2015 is located in the wall. However, since the length direction of the mounting groove in the wall is consistent with the length direction of the track, the extension direction of the second side 2015 is inconsistent with the length direction of the mounting groove. Thus, the second side 2015 is not blocked by the groove wall (or wall) of the mounting groove and is exposed to the outside. Therefore, the second power port 2018 can be used for the external product 30 to extend into, so that the external product 30 can be electrically connected to the circuit board assembly 204 in the installation space 2016.

[0039] Understandably, when the adapter base 20 is installed on a surface-mounted track, both the first side 2014 and the second side 2015 are exposed outside the wall, and both the first power port 2017 and the second power port 2018 allow external products 30 to extend into them. Compared to the prior art, this application provides the first power port 2017 and the second power port 2018 on both sides of the main frame 201 in different extension directions. The adapter base 20 is connected to either a surface-mounted or concealed track, and at least one of the first power port 2017 and the second power port 2018 can be exposed to the outside, allowing the power cord of the smart product to extend into and electrically connect with the circuit board assembly 204 in the installation space 2016. The adapter base 20 of this application is compatible with both surface-mounted and concealed tracks, greatly improving the practicality of the adapter base. The adapter device using this adapter base 20 can be applied to a variety of different home environments, providing users with more installation options.

[0040] See Figure 3 For ease of description, Figure 3The X direction represents the length direction X of the main frame 201. In one embodiment, the first side 2014 and the second side 2015 are two adjacent sides. The main frame 201 can be rectangular or polygonal. When the main frame 201 is rectangular, the first side 2014 and the second side 2015 are parallel to the length direction X and the width direction Y of the main frame 201, respectively. When the adapter base 20 is connected to the concealed track, the length direction of the track 10 is parallel to the length direction X of the main frame 201. At this time, the second side 2015 is perpendicular to the length direction of the track 10. The second side 2015 is completely exposed to the outside and is not blocked by the track 10 (or the wall), which facilitates the external product 30 to extend into the second power port 2018. If the main frame 201 is polygonal, the adjacent first side 2014 and the second side 2015 ensure that at least one side is not completely blocked by the track 10 (or the wall), which is beneficial for the connection of the external product 30.

[0041] See Figure 4 and Figure 5 The circuit board assembly 204 includes a circuit board 2043, a first connection terminal 2041, and a second connection terminal 2042. The first connection terminal 2041 and the second connection terminal 2042 are electrically connected to the circuit board 2043, respectively. The first connection terminal 2041 is disposed opposite to the first power port 2017, and the second connection terminal 2042 is disposed opposite to the second power port 2018. The first connection terminal 2041 and the second connection terminal 2042 are used for electrical connection with the external product 30.

[0042] In practical use, circuit board 2043 receives electrical energy from an external power source (which can be rail 10) and transmits the energy to external product 30 through the first connection terminal 2041 or the second connection terminal 2042. Specifically, external product 30 is usually equipped with a charging cable, such as a USB interface. Connecting the charging cable to the first connection terminal 2041 or the second connection terminal 2042 enables external product 30 to be powered. Therefore, the first connection terminal 2041 is positioned opposite to the first power port 2017, and the second connection terminal 2042 is positioned opposite to the second power port 2018. The first power port 2017 and the second power port 2018 have a guiding function, facilitating the connection of the charging connector of external product 30 to the first connection terminal 2041 or the second connection terminal 2042.

[0043] In one embodiment, the first connection terminal 2041 is inserted into the first power port 2017, and the second connection terminal 2042 is inserted into the second power port 2018. This arrangement increases the convenience of connecting the external product 30 with the first connection terminal 2041 and the second connection terminal 2042. On the other hand, the first power port 2017 or the second power port 2018 limits the charging cable of the external product 30, which is beneficial to the connection stability between the external product 30 and the first connection terminal 2041 or the second connection terminal 2042. At the same time, the charging cable does not need to be fully inserted into the installation space 2016, making it easy for the charging cable of the external product 30 to be removed from the first power port 2017 or the second power port 2018.

[0044] See again Figure 4 and Figure 5 , Figure 4 In the diagram, the X direction represents the length direction of the main frame 201, and the Y direction represents the width direction of the main frame 201. The length direction of the main frame 201 can be parallel to the extension direction of the track 10, and the width direction of the main frame 201 can be perpendicular to the extension direction of the track 10. In one embodiment, the first side 2014 is parallel to the length direction X of the main frame 201, and the second side 2015 is parallel to the width direction Y of the main frame 201. The IoT adapter base 20 also includes a plug 207, which is disposed in the installation space 2016 and connected to the main frame 201. The plug 207 has a through hole 2071. The second connection terminal 2042 is connected to the second power port 2018 through the through hole 2071.

[0045] It is understandable that the extension length of the main frame 201 in its length direction X is much greater than its extension length in its width direction Y. The size of the circuit board 2043 is designed according to the actual charging requirements. In order to save economic costs, the length of the circuit board 2043 is usually less than the length of the main frame 201.

[0046] The second power port 2018 is located on the second side 2015 of the main frame 201. Therefore, the second connection terminal 2042 on the circuit board assembly 204 inside the main frame 201 is far from the second power port 2018, which is not conducive to the connection between the external product 30 and the second connection terminal 2042. Based on this, this application provides a plug 207. Through the transition connection function of the plug 207, the second power port 2018 and the second connection terminal 2042 are interconnected. The plug 207 also acts as a guide, allowing the charging cable of the external product 30 to connect to the second connection terminal 2042 from the second power port 2018 through the through hole 2071 on the plug 207, which is beneficial for the accurate connection between the external product 30 and the second connection terminal 2042. At the same time, the plug 207 and the main frame 201 can be detachably connected, making the assembly of the adapter base 20 simpler.

[0047] It should be noted that the main frame 201 can be made by injection molding. The end cap 207 can also reduce the thickness of the local molding on the side of the main frame 201, which facilitates the manufacturing process of the main frame 201.

[0048] See Figure 5 and Figure 6 The adapter base 20 also includes a power connection part 202, which is connected to the main frame 201. One end of the power connection part 202 is connected to the circuit board assembly 204, and the other end extends out of the main frame 201 to be electrically connected to an external power source.

[0049] In one embodiment, one end of the power receiving part 202 extends out of the main frame 201 and is electrically connected to the track 10, which is electrically connected to an external power source. The other end of the power receiving part 202 is connected to the circuit board assembly 204 to provide power to the circuit board assembly 204. The circuit board assembly 204 then provides power to the external product 30, enabling the external product 30 to be powered on. The power receiving part 202 can be a power contact, which is simple in structure and easy to connect.

[0050] See Figure 6 In one embodiment, the main frame 201 includes a housing 2011, a bottom cover 2012, and a buckle 2013. The bottom cover 2012 is connected to the housing 2011, and the bottom cover 2012 and the housing 2011 enclose an installation space 2016. The buckle 2013 is connected to the bottom cover 2012 and is used to engage with an external power source.

[0051] Specifically, the bottom cover 2012 and the outer shell 2011 are detachably connected together. The buckle 2013 on the bottom cover 2012 is used to engage with the rail 10. The main frame 201 is connected to the rail 10 through the buckle 2013 and slides with the rail 10. At this time, the electrical contact part 202 extending out of the main frame 201 is electrically connected to the rail 10. With this configuration, the adapter base 20 is movably connected to the rail 10 through the engagement of the buckle 2013 with the rail 10, so that the adapter base 20 can slide along the length of the rail 10, realizing the flexible installation function of the adapter base 20 to meet the power supply needs of multiple locations.

[0052] See Figure 7In one embodiment, the adapter base 20 further includes an adapter 205 for connecting an external product 30 and for adjusting the connection angle of the external product 30. In practical applications, the main frame 201 has mounting holes. One end of the adapter 205 is inserted into the mounting hole, and the other end is threaded for threaded connection with the external product 30, so that the external product 30 is fixed to the adapter base 20. Then, the charging cable of the external product 30 is inserted from the first power port 2017 or the second power port 2018 and connected to the circuit board assembly 204 to realize the charging function. The adapter 205 can use imperial screws.

[0053] In one embodiment, the adapter base 20 further includes an elastic element 206, which is connected to the main frame 201 and protrudes from the main frame 201. The elastic element 206 has an adjustment hole opposite to the mounting hole. The adapter 205 passes through the adjustment hole and is inserted into the mounting hole. Since the elastic element 206 has the ability to deform, when the external product 30 is connected to the adapter 205 and connected to the elastic element 206, the user can continue to rotate the external product 30 to squeeze the elastic element 206 until the external product 30 is rotated to a suitable angle, such as rotating the charging port of the external product 30 to the same orientation as the first power port 2017 or the second power port 2018. This makes the connection between the external product 30 and the adapter base 20 more stable.

[0054] See Figure 8 This application also provides a connecting device, which includes a track 10 and the aforementioned connecting base 20. The track 10 includes a guide rail 101 and a conductive sheet 102. The main frame 201 in the connecting base 20 is movably connected to the guide rail 101. Specifically, the main frame 201 includes a buckle 2013, and the guide rail 101 is provided with a snap-fit ​​part 1013 along its length direction. The main frame 201 and the guide rail 101 are movably connected by snap-fit ​​between the buckle 2013 and the snap-fit ​​part 1013. Furthermore, the main frame 201 also includes a first magnetic suction member 203, which is connected to the bottom cover 2012. The guide rail 101 is connected to a second magnetic suction member 103. The magnetic connection between the first magnetic suction member 203 and the second magnetic suction member 103 further enhances the connection stability between the main frame 201 and the guide rail 101.

[0055] The conductive sheet 102 is connected to the side of the guide rail 101 near the main body frame 201. The conductive sheet 102 is connected to an external power source. When the main body frame 201 and the guide rail 101 are snapped together 2013, one end of the power receiving part 202 extends out of the main body frame 201 and is electrically connected to the conductive sheet 102. The other end of the power receiving part 202 is connected to the circuit board assembly 204 so as to provide the power of the external power source to the circuit board assembly 204, thereby enabling the circuit board assembly 204 to charge the external product 30.

[0056] The guide rail 101 includes a bottom 1011 and side portions 1012 symmetrically arranged on both sides of the bottom 1011. The side portions 1012 extend away from the bottom 1011, and the side portions 1012 and the bottom 1011 enclose a receiving space 1014.

[0057] In one embodiment, when the main frame 201 is connected to the surface-mounted track, such as Figure 8 As shown, the first power port 2017 and the second power port 2018 are both located outside the accommodating space 1014. At this time, the charging cable of the external product 30 can be inserted into both the first power port 2017 and the second power port 2018.

[0058] In one embodiment, when the main frame 201 is connected to the concealed track, such as Figure 9 As shown, the side 1012 of the concealed track extends to the first side 2014 covering the main frame 201. The main frame 201 is located in the receiving space 1014. The side 1012 of the guide rail 101 covers the first power port 2017 and the second power port 2018 is located in the receiving space 1014. The second power port 2018 is exposed to the outside. At this time, the charging cable of the external product 30 can be inserted into the second power port 2018.

[0059] It is understandable that the first side 2014 of the main frame 201 is parallel to the extension direction of the guide rail 101, and the second side 2015 of the main frame 201 is perpendicular to the extension direction of the guide rail 101. With this arrangement, when the adapter base 20 is connected to the concealed track, the second side 2015 is perpendicular to the extension direction of the guide rail 101, which ensures that the second side 2015 is exposed and not blocked by the side 1012 of the guide rail 101, which is beneficial for the connection of external products 30.

[0060] Unlike existing technologies, this application provides an adapter device, including an adapter base 20 and a track 10, with the adapter base 20 connected to the track 10. The adapter base 20 includes a main frame 201 and a circuit board assembly 204. The main frame 201 has an installation space 2016 inside, and the circuit board assembly 204 is disposed within the installation space 2016. The main frame 201 includes a first side 2014 and a second side 2015 extending in different directions. The first side 2014 has a first power port 2017 communicating with the installation space 2016, and the second side 2015 has a second power port 2018 communicating with the installation space 2016. An external product 30 extends into the installation space 2016 from the first power port 2017 and the second power port 2018 and is electrically connected to the circuit board assembly 204. Compared to existing technologies, this application provides a first power port 2017 and a second power port 2018 on both sides of the main frame 201 in different extension directions. Whether the adapter base 20 is connected to a surface-mounted or recessed track, at least one of the first power port 2017 and the second power port 2018 can be exposed externally, allowing the power cord of the smart product to extend into and electrically connect to the circuit board assembly 204 within the installation space 2016.
