[0033] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0034] See also Figure 1 An embodiment of the present application provides a transfer device, including a transfer base 20 and a track 10. The transfer base 20 is connected to the track 10. The transfer base 20 is used to connect to a smart product and charge the smart product.

[0035] It should be noted that the adapter base 20 can be a power socket with power supply or network connection function. The adapter base 20 is provided with a power port for connecting to the power cord of the smart product; the track 10 is used to connect to the circuit to provide power to the adapter base 20. Unlike the traditional socket, the adapter base 20 can be connected to any position of the track 10 along its length, so that the installation position of the adapter base 20 is more flexible and more convenient to use.

[0036] The above-mentioned adapter base 20 includes a main body 201 and a bottom cover 202, the bottom cover 202 is connected to the main body 201, and is connected to the track 10; the main body 201 is provided with a first mounting hole 2011 and at least one second mounting hole 2012, one of the second mounting holes 2012 or the first mounting hole 2011 is used to install a first smart product 30 fixed by a single hole; at least two of the at least one second mounting hole 2012, or the first mounting hole 2011 and at least one second mounting hole 2012 are used to jointly install a second smart product 40 fixed by multiple holes.

[0037] In one embodiment, in addition to the power supply requirement, some smart products are also installed on the track 10 through the adapter base 20 for use. For example, products such as gateways, cameras and sensors are installed on the adapter base 20 and can move with the adapter base 20, thereby realizing the flexible installation function of the smart product and effectively avoiding the separation of the smart product from the power port of the adapter base 20; based on this, the adapter base 20 of the present application is also provided with a first mounting hole 2011 and a second mounting hole 2012 to meet the connection requirements of various smart products. Smart products are generally divided into a first smart product fixed with a single hole and a second smart product 40 fixed with multiple holes. Specifically, the first smart product 30 fixed with a single hole refers to the smart product itself having only one fixing hole, and the second smart product 40 fixed with multiple holes refers to the smart product itself having multiple fixing holes.

[0038] See also Figures 1 to 3At least two second mounting holes 2012 are used to fix the second smart product 40, or the first mounting hole 2011 and at least one second mounting hole 2012 are used to fix the second smart product 40 to adapt to multiple models of the second smart product 40, such as a second smart product 40 with two fixing holes or three fixing holes.

[0039] Compared with the prior art, the adapter base 20 of the present application is provided with a first mounting hole 2011 and at least one second mounting hole 2012, which meet the installation requirements of most smart products on the market. A single first mounting hole 2011 or a single second mounting hole 2012 can be used to install a single-hole fixed first smart product 30, and multiple second mounting holes 2012 can be used to install a multi-hole fixed second smart product 40. The first mounting hole 2011 and multiple second mounting holes 2012 can also be used to install a multi-hole fixed second smart product 40, so that the adapter base 20 of the present application is adaptable to a variety of smart products; the adapter device using this adapter base 20 can realize flexible installation of a variety of smart products, enhancing the practicality and convenience of the device.

[0040] In one embodiment, the first mounting hole 2011 and the at least one second mounting hole 2012 are arranged along the length direction X of the main body 201 .

[0041] See also Figure 1 and Figure 2 For the convenience of description, the X direction represents the length direction of the main body 201. Along the length direction X of the main body 201, more first mounting holes 2011 and second mounting holes 2012 can be set, and the distance range between adjacent mounting holes can be set larger. In this way, various models of porous smart products can be adapted.

[0042] Among them, the first mounting hole 2011 and the second mounting hole 2012 have different apertures or different threads, which can meet the installation requirements of various different models of smart products, such as a first smart product 30 using ordinary screws and a first smart product 30 using imperial screws, or a second smart product 40 with three fixing holes, one of which has a different aperture.

[0043] It should be noted that imperial screws and metric screws generally refer to two different thread standard systems, which differ in size, specification and thread series.

[0044] The first mounting hole 2011 and the second mounting hole 2012 are both provided on a side of the main body 201 opposite to the bottom cover 202. The bottom cover 202 is used to connect with the track 10. The first mounting hole 2011 and the second mounting hole 2012 are provided on the side opposite thereto, which can provide a larger installation space for the smart product and prevent the track 10 from interfering with the installation of the smart product.

[0045] See also Figure 4 In one embodiment, the number of the second mounting holes 2012 is multiple, and the multiple second mounting holes 2012 are distributed on opposite sides of the first mounting hole 2011. Since the fixing holes of different apertures in the second smart product 40 are usually located in the middle, the multiple second mounting holes 2012 are distributed on opposite sides of the first mounting hole 2011 to meet the installation requirements of most second smart products 40 on the market; at the same time, the first mounting holes 2011 and the second mounting holes 2012 are distributed more evenly on the main body 201, and the design is more reasonable.

[0046] Specifically, the number of the second mounting holes 2012 can be an even number, such as two, four, or the like, and the plurality of second mounting holes 2012 are symmetrically distributed on opposite sides of the first mounting hole 2011, and the first mounting hole 2011 is located at the center of the side of the main body 201. In this way, compared with the above-mentioned embodiment, the first mounting hole 2011 and the second mounting hole 2012 are more evenly distributed on the main body 201. The first mounting hole 2011 is located at the center of the main body 201, which is usually also the center of gravity, and the second mounting holes 2012 are symmetrically distributed on opposite sides of the first mounting hole 2011, that is, symmetrically arranged along the center of gravity of the main body 201. In this way, when the first mounting hole 2011 is installed with the first smart product 30 fixed by a single hole, the center of gravity of the first smart product 30 is aligned with the center of gravity of the main body 201. 1 is approximately coincident with the center of gravity of the main body 201, thereby improving the load-bearing capacity of the main body 201; at the same time, the center of gravity of the first mounting hole 2011 and the smart product is also approximately coincident, so when the first mounting hole 2011 and the second mounting hole 2012 are used to install the second smart product 40 fixed by multiple holes, the second mounting holes 2012 symmetrically located on both sides thereof are subjected to the same gravity of the second smart product 40, and the weight of the second smart product 40 is evenly distributed on the plurality of second mounting holes 2012, thereby improving the load-bearing capacity of the second mounting holes 2012.

[0047] See again Figure 4 The adapter base 20 further includes an adapter screw 204, and the adapter screw 204 is detachably connected to the first mounting hole 2011. The adapter screw 204 can be an English screw.

[0048] In one embodiment, the single-hole fixed smart product can be a first smart product 30 that is provided with an imperial nut. When installing such a first smart product 30, it is necessary to connect it to the first mounting hole 2011 through an imperial screw, and then connect the first smart product 30 to the imperial screw to achieve the connection of the first smart product 30.

[0049] It is understandable that the imperial screw is a double-headed screw. Specifically, one end of the imperial screw is provided with a thread for threaded connection with the first smart product 30, and the other end may or may not be provided with a thread for detachable connection with the first mounting hole 2011.

[0050] The adapter base 20 further includes a fastening screw 205, which is used to penetrate the first smart product 30 or the second smart product 40 and is connected to at least one of the first mounting hole 2011 and the second mounting hole 2012 to fix the first smart product 30 or the second smart product 40. The fastening screw 205 can be a metric screw.

[0051] It should be noted that the single-hole fixed smart products are generally divided into the first smart products 30 with imperial nuts and the first smart products 30 with metric nuts, while the multi-hole fixed smart products are mostly the second smart products 40 with metric nuts.

[0052] Based on this, the adapter base 20 also includes a fastening screw 205, which is a metric screw. When fixing the first smart product 30 or the second smart product 40, the threaded end of the fastening screw 205 is passed through the fixing hole on the first smart product 30 or the second smart product 40, and is threadedly connected to the first mounting hole 2011 or the second mounting hole 2012 to achieve the connection of the first smart product 30 or the second smart product 40.

[0053] It is understandable that the metric screw may be a countersunk screw. Specifically, a countersunk screw has a thread at one end and a countersunk head or a flat head at the other end.

[0054] See also Figure 5 In one embodiment, the adapter base 20 also includes a fastening base 203, which is located in the main body 201 and connected to the main body 201. The fastening base 203 is provided with a first fixing hole 2031 and a second fixing hole 2032 which are respectively opposite to and connected to the first mounting hole 2011 and the second mounting hole 2012.

[0055] In order to enhance the connection stability between the smart product and the adapter base 20, the present application provides a fastening base 203, and the adapter screw 204 and the fastening screw 205 pass through the first mounting hole 2011 and the second mounting hole 2012 and are connected to the first fixing hole 2031 and the second fixing hole 2032. The gravity of the smart product is transmitted to the fastening base 203 through the adapter screw 204 and the fastening screw 205. The fastening base 203 itself has rigidity and a certain thickness and can withstand greater stress, thereby avoiding the gravity from being transmitted to the main body 201 and preventing the main body 201 from deformation.

[0056] The material of the fastening base 203 can be metal, such as iron or copper, which effectively enhances its structural rigidity.

[0057] See also Figure 6 In one embodiment, the adapter base 20 also includes a fixing member 206, the main body 201 includes a shell 2013 and a gasket 2014, the fastening base 203 is located in the shell 2013 and connected to the shell 2013, the gasket 2014 is arranged between the fastening base 203 and the shell 2013, the gasket 2014 is provided with a first mounting hole 2011 and a second mounting hole 2012, the fixing member 206 passes through the fastening base 203 and is connected to the shell 2013 to fix the fastening base 203 and the shell 2013.

[0058] Specifically, the fixing member 206 fixes the fastening base 203 to the housing 2013. Since the gasket 2014 is arranged between the fastening base 203 and the housing 2013, the fastening base 203 generates an abutting force on the gasket 2014, and the abutting force abuts the gasket 2014 to the housing 2013 to achieve the fixing of the gasket 2014. The gasket 2014 can at least partially protrude from the housing 2013, and the first mounting hole 2011 and the second mounting hole 2012 are provided at the position where the gasket 2014 protrudes from the housing 2013, so as to facilitate the connection between the fastening screw 205 and the adapter screw 204; preferably, the material of the gasket 2014 can be soft glue. When the single-hole first smart product 30 abuts against the gasket 2014, the smart product can be continuously screwed to adjust the connection angle between the smart product and the main body 201 through the flexibility of the soft glue, which is beneficial to the connection stability between the smart product and the adapter base 20.

[0059] The fixing member 206 may be a screw or a rivet, which has low cost and is easy to disassemble.

[0060] See also Figure 7The adapter device includes a track 10 and the above-mentioned adapter base 20, wherein the track 10 includes a guide rail 101 and a buckle 103, the buckle 103 is connected to the guide rail 101, and is connected to the bottom cover 202 of the adapter base 20 and slides with the bottom cover 202; the adapter base 20 slides with the guide rail 101 through the bottom cover 202, so that the adapter base 20 can move to a specified position along the length direction of the guide rail 101, so that the adapter base 20 drives the smart product connected thereto to move to the specified position, realizing the flexible use function of the smart product and expanding the installation range of the smart product.

[0061] In one embodiment, a first magnetic member may be provided on the guide rail 101, and a second magnetic member may be provided inside the main body 201. The guide rail 101 and the main body 201 are magnetically connected by the first magnetic member and the second magnetic member, which further enhances the connection stability between the adapter base 20 and the track 10 and facilitates the sliding of the adapter base 20 on the track 10.

[0062] See again Figure 7 The guide rail 101 further includes a conductive sheet 102, which is connected to one side of the guide rail 101 close to the main body 201, and is electrically connected to the main body 201. Specifically, the main body 201 is provided with a power contact, and when the bottom cover 202 is engaged with the buckle 103, the power contact is connected to the conductive sheet 102, and the conductive sheet 102 is connected to a household or commercial circuit. In this way, the electrical connection between the track 10 and the adapter base 20 is realized through the conductive sheet 102, so as to provide the adapter base 20 with electrical energy, and further realize the function of the adapter base 20 to power the smart product.

[0063] Different from the prior art, the present application provides an adapter device, including an adapter base 20 and a track 10, the adapter base 20 is connected to the track 10; the adapter base 20 includes a main body 201 and a bottom cover 202, the bottom cover 202 is connected to the main body 201, and is connected to the track 10; the main body 201 is provided with a first mounting hole 2011 and at least one second mounting hole 2012, one of the second mounting holes 2012 or the first mounting hole 2011 is used to install a first smart product 30 fixed by a single hole; at least two of the at least one second mounting hole 2012, or the first mounting hole 2011 and at least one second mounting hole 2012 are used to jointly install a second smart product 40 fixed by multiple holes. Compared with the prior art, the adapter base 20 of the present application is provided with a first mounting hole 2011 and at least one second mounting hole 2012, which meet the installation requirements of most smart products on the market. A single first mounting hole 2011 or a single second mounting hole 2012 can be used to install a single-hole fixed first smart product 30, and multiple second mounting holes 2012 can be used to install a multi-hole fixed second smart product 40. The first mounting hole 2011 and multiple second mounting holes 2012 can also be used to install a multi-hole fixed second smart product 40, so that the adapter base 20 of the present application is adaptable to a variety of smart products; the adapter device using this adapter base 20 can realize flexible installation of a variety of smart products, enhancing the practicality and convenience of the device.

[0064] The above is only a specific implementation method of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
