The present application provides a connection structure, a power supply device and a sofa. The connection structure includes a socket assembly, an elastic limit assembly and a plug assembly. The socket assembly includes a mounting seat, and the mounting seat is provided with a plug-in slot and a mounting hole that are interconnected. One end of the elastic limit assembly is installed in the mounting hole, and the other end of the elastic limit assembly protrudes from the plug-in slot. The plug assembly includes a plug body and a pusher, and the pusher protrudes and is connected to the outside of the plug body. The plug body and the pusher are both inserted into the plug-in slot. The elastic limit assembly is used to protrude from the plug-in slot when the plug body and the pusher are inserted into the plug-in slot, so that the pusher is limited in the plug-in slot. The pusher is used to abut and push the elastic limit assembly to contract when plugging and unplugging the plug body and the pusher. The force required to pull out the plug assembly is relatively large, thereby improving the connection reliability between the plug body and the pusher, and avoiding the problem of accidental separation of the plug assembly and the socket assembly.

Description

In addition to the original traditional functions, these smart home products also have the functions of leisure, entertainment and massage. In order to achieve leisure, entertainment and massage, the smart home products need to be powered on.

[0003] In traditional technology, smart home products are connected to household sockets through electric wires, so that household electricity can power smart home products. However, once the power grid company stops supplying power, smart home products can no longer work. As a result, a power supply device has appeared on the market. This power supply device is electrically connected to smart home products through a traditional charging cable, that is, the two ends of the traditional charging cable are directly plugged into the power supply device and the smart home product respectively. However, this connection method is not reliable, and the electrical connection between the power supply device and the smart home product is easy to disconnect after being pulled, causing the power supply device to stop supplying power to the smart home product. For example, when the user accidentally pulls the charging cable, the two ends of the charging cable are separated from the power supply device and the smart home product respectively, resulting in poor reliability of the electrical connection between the power supply device and the smart home product.

[0032] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly understood.

[0033] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0035] like Figures 1 to 3As shown, a connection structure of an embodiment includes a socket assembly 100, an elastic limiting assembly 300 and a plug assembly 500, wherein the socket assembly 100 includes a mounting seat 110, and the mounting seat 110 is provided with a plug slot 111 and a mounting hole 113 that are interconnected. One end of the elastic limiting assembly 300 is installed in the mounting hole 113, and the other end of the elastic limiting assembly 300 protrudes from the plug slot 111. The plug assembly 500 includes a plug body 510 and a pusher 530, and the pusher 530 protrudes and is connected to the outside of the plug body 510. The plug body 510 and the pusher 530 are both inserted into the plug slot 111, and the elastic limiting assembly 300 is used to protrude from the plug slot 111 when the plug body 510 and the pusher 530 are inserted into the plug slot 111, so that the pusher 530 is limited in the plug slot 111. The pushing member 530 is used to abut against and push the elastic limiting assembly 300 to contract when plugged into or pulled out of the plug slot 111 , and an angle exists between the direction in which the pushing member 530 is plugged into or pulled out of the plug slot 111 and the elastic expansion and contraction direction of the elastic limiting assembly 300 .

[0036] like Figure 1 As shown, in this embodiment, the mounting seat 110 is fixed on the smart home product so that the socket assembly 100 can be stably mounted on the smart home product, and the circuit contact of the smart home product is arranged in the plug slot 111. The plug assembly 500 is used to connect to the power source, and the contact of the power source is arranged on the surface of the plug body 510. When the plug assembly 500 is inserted into the plug slot 111 of the socket assembly 100, the contact of the power source contacts the contact of the smart home product, thereby realizing the electrical connection between the power source and the smart home product.

[0037] like Figure 2 and Figure 3 As shown, further, the plug slot 111 includes a bottom surface and a side surface arranged around the bottom surface, that is, the slot wall of the plug slot 111 includes a bottom surface and a side surface arranged around the bottom surface. The mounting hole 113 is located on the side surface of the plug slot 111, that is, the mounting hole 113 is connected to the plug slot 111 through the side surface of the plug slot 111. One end of the elastic limit assembly 300 is installed in the mounting hole 113, and the other end of the elastic limit assembly 300 protrudes from the plug slot 111 through the side surface of the plug slot 111, and the other end of the elastic limit assembly 300 extends into the plug slot 111 through the side surface of the plug slot 111. When the plug body 510 and the pushing member 530 are inserted into and pulled out of the insertion slot 111, the pushing member 530 abuts against one end of the elastic limiting component 300 protruding from the insertion slot 111 to push the elastic limiting component 300 to contract, thereby causing one end of the elastic limiting component 300 to move toward the direction close to the mounting hole 113, thereby causing the elastic limiting component 300 to leave the movement path of the pushing member 530.

[0038] Furthermore, there is an angle between the direction in which the pushing member 530 is inserted and removed from the plug-in slot 111 and the telescopic direction of the elastic limiting assembly 300, that is, there is an angle between the movement direction of the pushing member 530 and the telescopic direction of the elastic limiting assembly 300, that is, the movement direction of the pushing member 530 is not parallel to the telescopic direction of the elastic limiting assembly 300, so that the component of the abutment force of the pushing member 530 acting on the elastic limiting assembly 300 in the telescopic direction of the elastic limiting assembly 300 is smaller than the external force required for inserting and removing the pushing member 530, thereby requiring a larger external force to insert and remove the pushing member 530.

[0039] Furthermore, when the plug body 510 and the pusher 530 are inserted into the insertion slot 111, one end of the elastic limiting component 300 protrudes from the insertion slot 111, so that the pusher 530 is limited in the insertion slot 111, that is, one end of the elastic limiting component 300 limits the movement of the pusher 530 in the insertion slot 111, that is, one end of the elastic limiting component 300 blocks the movement path of the pusher 530 to block the movement of the pusher 530. When the plug body 510 and the pusher 530 are pulled out of the insertion slot 111, one end of the elastic limiting component 300 protrudes from the insertion slot 111, so that one end of the elastic limiting component 300 blocks the movement path of the pusher 530, so that the plug body 510 and the pusher 530 need external force to be inserted into the insertion slot 111 again.

[0040] In the above-mentioned connection structure, after the plug body 510 and the pushing member 530 are inserted into the plug-in slot 111, the elastic limiting component 300 protrudes from the plug-in slot 111, so that the pushing member 530 is limited in the plug-in slot 111, and there is an angle between the direction in which the pushing member 530 is inserted and pulled out of the plug-in slot 111 and the extension and contraction direction of the elastic limiting component 300, so that only a part of the force for pulling out the plug body 510 and the pushing member 530 is used to push the elastic limiting component 300 to compress, so that when pulling out the plug body 510 and the pushing member 530, a larger force is required to compress the elastic limiting component 300 and leave the movement path of the pushing member 530, so that the force required to pull out the plug assembly 500 is larger, thereby improving the connection reliability between the plug assembly 500 and the socket assembly 100, and avoiding the problem of accidental separation of the plug assembly 500 and the socket assembly 100.

[0041] It should be noted that, in this embodiment, the force required to pull the plug body 510 and the pusher 530 out of the insertion slot 111 is equal to 10 N. Of course, in other embodiments, the force required to pull the plug body 510 and the pusher 530 out of the insertion slot 111 is not limited to 10 N, and the force required to pull the plug body 510 and the pusher 530 out of the insertion slot 111 can be adjusted according to the use environment.

[0042] like Figure 5 and Figure 6 As shown, in one of the embodiments, the two sides of the pushing member 530 respectively abut against the groove wall of the plug-in groove 111 and the end of the elastic limiting component 300 adjacent to the plug-in groove 111, that is, the two sides of the pushing member 530 respectively abut against the bottom surface of the plug-in groove 111 and the end of the elastic limiting component 300 adjacent to the plug-in groove 111, so that the bottom surface of the plug-in groove 111 and the elastic limiting component 300 clamp the pushing member 530 together, avoiding the problem of position deviation of the pushing member 530, thereby improving the stability of the plug assembly 500.

[0043] like Figure 6 As shown, in one embodiment, the elastic limiting assembly 300 includes an elastic element 310 and an abutment member 330, the elastic element 310 is disposed in the mounting hole 113, one end of the elastic element 310 adjacent to the plug slot 111 is connected to the abutment member 330, and at least a portion of the abutment member 330 is located in the plug slot 111. In this embodiment, when the plug body 510 and the pusher 530 are inserted into the plug slot 111 together, the pusher 530 abuts against the abutment member 330, so that the abutment member 330 pushes the elastic element 310 to compress, so that the abutment member 330 moves in the direction of compressing the elastic element 310, so that the abutment member 330 leaves the moving path of the pusher 530, and then the plug body 510 and the pusher 530 are smoothly inserted into the plug slot 111. After the plug body 510 and the pushing member 530 are inserted into the plug-in slot 111, the pushing member 530 is separated from the abutting member 330, so that the elastic element 310 extends and pushes the abutting member 330 into the plug-in slot 111, so that the abutting member 330 blocks the pushing member 530, and further the pushing member 530 is limited in the plug-in slot 111, thereby avoiding the problem of the plug assembly 500 being separated from the mounting seat 110 when there is no external force.

[0044] Further, when the plug body 510 and the pushing member 530 are pulled out of the plug slot 111, the pushing member 530 abuts against the abutting member 330, so that the abutting member 330 pushes the elastic element 310 to be compressed, so that the abutting member 330 moves toward the mounting hole 113, so that the abutting member 330 leaves the movement path of the pushing member 530, and then the plug body 510 and the pushing member 530 are pulled out of the plug slot 111. After the plug body 510 and the pushing member 530 are pulled out of the plug slot 111, the elastic member 310 stretches and pushes the abutting member 330 into the plug slot 111, so that the abutting member 330 enters the movement path of the pushing member 530. In this way, under the push of the pusher 530, the abutment member 330 compresses the elastic element 310 and leaves the movement path of the pusher 530, avoiding the problem of the pusher 530 directly contacting the elastic element 310, thereby preventing the elastic element 310 from entering the movement path of the pusher 530 after deformation and interfering with the movement of the pusher 530, ensuring that the plug assembly 500 is smoothly plugged into and out of the socket assembly 100. In other embodiments, the elastic element 310 is a spring, a rubber spring or other springs in the prior art.

[0045] like Figure 6 As shown, in one embodiment, the portion of the abutment member 330 located in the insertion slot 111 is provided with an arc surface 331, and the arc surface 331 elastically abuts against the pusher 530. In this embodiment, the pusher 530 contacts the arc surface 331 of the abutment member 330, so that the pusher 530 abuts against the abutment member 330 smoothly, avoiding the problem of large stress concentration at the abutment point between the pusher 530 and the abutment member 330, thereby improving the service life of the pusher 530 and the abutment member 330. It can be understood that the abutment member 330 can be a sphere or other structure with an arc surface 331.

[0046] Of course, in other embodiments, the portion of the abutment member 330 located at the insertion slot 111 is provided with two opposite inclined surfaces, one of which is adjacent to the bottom surface of the insertion slot 111, and the other is away from the bottom surface of the insertion slot 111. When the pusher 530 is inserted into the insertion slot 111, the pusher 530 abuts against the inclined surface of the abutment member 330 away from the bottom surface of the insertion slot 111, and the pusher 530 pushes the abutment member 330 away from the movement path of the pusher 530. When the pusher 530 is pulled out of the insertion slot 111, the pusher 530 abuts against the inclined surface of the abutment member 330 adjacent to the bottom surface of the insertion slot 111, and the pusher 530 pushes the abutment member 330 away from the movement path of the pusher 530.

[0047] like Figure 6As shown, in one embodiment, the elastic limiting assembly 300 further includes an elastic mounting member 350, and the elastic mounting member 350 includes a receiving portion 351 and a limiting portion 353. The receiving portion 351 is provided with a receiving space, and the elastic element 310 and the abutting member 330 are both movably arranged in the receiving space, and the receiving portion 351 is arranged in the mounting hole 113. The limiting portion 353 is provided with an abutting hole, and the limiting portion 353 is connected to one end of the receiving portion 351 adjacent to the plug slot 111, and the abutting hole is communicated with the receiving space, and a portion of the abutting member 330 extends into the plug slot 111. In this embodiment, the elastic element 310 and the abutment member 330 are both arranged in the accommodating space, one end of the elastic element 310 adjacent to the plug-in slot 111 is connected to the abutment member 330, and a portion of the abutment member 330 enters the plug-in slot 111 through the abutment hole of the limiting portion 353, that is, the elastic element 310 is completely arranged in the accommodating space, avoiding the problem of the elastic element 310 extending into the plug-in slot 111, thereby avoiding the elastic element 310 from being directly abutted by the pushing member 530 and entering the movement path of the pushing member 530, thereby avoiding the problem of the elastic element 310 interfering with the movement of the pushing member 530, thereby ensuring that the plug assembly 500 is smoothly plugged in and out of the socket assembly 100.

[0048] In one embodiment, the accommodating portion 351 is overmolded on the mounting seat 110. In this embodiment, when connecting the accommodating portion 351 and the mounting seat 110, the accommodating portion 351 is first placed in a mold for molding the mounting seat 110; then, molten plastic is filled into the mold; after the molten plastic is cooled, the mounting seat is molded, and the accommodating portion 351 is adhered to the mounting seat 110. Since the accommodating portion 351 is overmolded on the mounting seat 110, the accommodating portion 351 is adhered to the mounting seat 110, so that there is no gap between the accommodating portion 351 and the mounting seat 110, the movement of the accommodating portion 351 relative to the mounting seat 110 is avoided, and the position stability of the accommodating portion 351 is improved.

[0049] like Figure 2 and Figure 6As shown, in one embodiment, the mounting seat 110 is also provided with an anti-plastic sticking groove 115, and the anti-plastic sticking groove 115 is located between the mounting hole 113 and the plug-in slot 111, and the mounting hole 113 is connected with the plug-in slot 111 through the anti-plastic sticking groove 115, the limiting portion 353 is located in the anti-plastic sticking groove 115, and part of the abutment 330 enters the plug-in slot 111 through the abutment hole and the anti-plastic sticking groove 115 in turn. In this embodiment, when the accommodating portion 351 is overmolded on the mounting seat 110, the molten plastic flows out from the mounting hole 113. Since the limiting portion 353 is located in the anti-plastic sticking groove 115, the molten plastic flowing out of the mounting hole 113 flows to the side wall of the limiting portion 353 and solidifies, preventing the molten plastic from flowing through the abutment hole to the abutment 330, thereby avoiding the problem of the molten plastic adhering the abutment 330 to the limiting portion 353, and ensuring that the abutment 330 can push the elastic element 310 to compress.

[0050] like Figure 2 As shown, in one embodiment, the plug-in slot 111 includes a guide slot 111a and a positioning slot 111c that are interconnected, the extension direction of the guide slot 111a is parallel to the plug-in direction of the plug body 510, the guide slot 111a is adapted to the plug body 510, and the plug body 510 is inserted into the guide slot 111a. The positioning slot 111c is also connected to the mounting hole 113, the positioning slot 111c is adapted to the push member 530, and the push member 530 is inserted into the positioning slot 111c. In this embodiment, since the guide groove 111a is matched with the plug body 510, and the positioning groove 111c is matched with the pusher 530, the installation position of the plug assembly 500 can be determined by aligning the plug body 510 and the pusher 530 with the guide groove 111a and the positioning groove 111c respectively, which saves the time of aligning the plug body 510 and improves the efficiency of inserting the plug assembly 500 into the socket assembly 100. In addition, since the extension direction of the guide groove 111a is parallel to the plugging direction of the plug body 510 and the guide groove 111a is matched with the plug body 510, the guide groove 111a guides the plug body 510, so that the guide groove 111a guides the plug assembly 500, further improving the efficiency of inserting the plug assembly 500 into the mounting seat 110.

[0051] like Figure 2 and Figure 3As shown, in one embodiment, the socket assembly 100 further includes an anti-rotation member 130, which is disposed on the slot wall of the plug slot 111. The plug body 510 is provided with an anti-rotation slot 511 on one side adjacent to the plug slot 111, and the anti-rotation member 130 is inserted into the anti-rotation slot 511. In this embodiment, after the plug body 510 and the push member 530 are inserted into the plug slot 111, the anti-rotation member 130 is also inserted into the anti-rotation slot 511, so that the anti-rotation member 130 limits the rotation of the plug body 510, thereby avoiding the problem of the plug assembly 500 rotating in the plug slot 111, thereby improving the position stability of the plug assembly 500.

[0052] It is understood that when the flow rate of the molten plastic is fast, the molten plastic will enter the gap between the abutment member 330 and the limiting portion 353, thereby bonding the abutment member 330 to the limiting portion 353. In order to avoid the above problems, as Figure 6 As shown, in one embodiment, the elastic mounting member 350 further includes a plastic blocking portion 355, one end of which is connected to the outer side of the limiting portion 353, and a plastic containing groove 3551 is provided at one end of the plastic blocking portion 355 away from the outer side of the limiting portion 353, and the plastic containing groove 3551 is arranged opposite to the outer side of the limiting portion 353. In this way, when the molten plastic flows through the outer side of the limiting portion 353 and enters the plastic containing groove 3551 of the plastic blocking portion 355, the plastic containing groove 3551 plays a role in storing the molten plastic, thereby preventing the molten plastic from flowing into the gap between the abutment member 330 and the limiting portion 353, thereby preventing the abutment member 330 from losing its movement function due to adhesion to the limiting portion 353. Furthermore, the elastic mounting member 350 further includes a paraffin layer, and the paraffin layer is coated on the groove wall of the plastic containing groove 3551. The paraffin layer is used to absorb the heat of the molten plastic to shorten the solidification time of the molten plastic, and further avoid the problem that the abutment member 330 is adhered to the limiting portion 353 due to the molten plastic.

[0053] like Figure 6As shown, in one embodiment, an adjustment hole 3511 is provided at one end of the accommodating portion 351 away from the abutting member 330, and a threaded hole 117 communicating with the adjustment hole 3511 is provided at the mounting seat 110. The elastic limit assembly 300 further includes a force adjustment member 370, one end of which is passed through the threaded hole 117 and the adjustment hole 3511 and abuts against the elastic element 310, wherein the force adjustment member 370 is threadedly connected with the threaded hole 117. In this embodiment, the force adjustment member 370 is rotated to adjust the length of the force adjustment member 370 extending into the accommodating portion 351, so as to adjust the compression amount of the elastic element 310, thereby adjusting the elastic force of the elastic element 310, thereby adjusting the force required for the abutting member 330 to push the elastic element 310 to compress, and then adjusting the difficulty of the plug assembly 500 being pulled out of the socket assembly 100. In addition, when the elastic element 310 is damaged, the elastic element 310 can be replaced after the force adjustment member 370 is screwed out, which facilitates the replacement of the elastic element 310. It can be understood that the force adjustment member 370 is a bolt, a stud, a screw or other fasteners in the prior art.

[0054] In order to prevent moisture in the air from corroding the elastic element 310, in one embodiment, the elastic limiting assembly 300 further includes a sealing member 390, which is disposed between the accommodating portion 351 and the end of the force adjusting member 370 away from the accommodating portion 351, and the sealing member 390 abuts against the accommodating portion 351 and the force adjusting member 370 respectively, so as to close the gap between the accommodating portion 351 and the end of the force adjusting member 370 away from the accommodating portion 351. Further, the elastic limiting assembly 300 further includes an elastic coating layer, which coats the abutting member 330, and the elastic coating layer elastically abuts against the limiting portion 353, so that the elastic coating layer closes the gap between the abutting member 330 and the limiting portion 353. In this way, after the plug assembly 500 is inserted into the socket assembly 100, the accommodating space of the accommodating portion 351 is in a closed state, and moisture in the air cannot enter the accommodating space to corrode the elastic element 310, thereby avoiding the problem of corrosion of the elastic element 310 and further improving the stability of the plug assembly 500 inserted in the socket assembly 100.

[0055] In order to make the plug assembly 500 easier to insert into the socket assembly 100, in one embodiment, an inclined surface 531 is provided on the outer side of the push member 530, and the inclined surface 531 abuts against the abutment member 330 and is arranged toward the abutment member 330 when the push member 530 is inserted into the insertion slot 111. In this embodiment, when the push member 530 is inserted into the insertion slot 111, the inclined surface 531 abuts against the abutment member 330 and is arranged toward the abutment member 330, so that the direction of the abutment force of the push member 530 on the abutment member 330 forms an acute angle with the elastic element 310, so that more components of the abutment force are used to push the elastic element 310 to contract, thereby reducing the force required to insert the plug assembly 500 into the socket assembly 100. In this way, while ensuring that the plug assembly 500 requires a greater force to be pulled out of the socket assembly 100, the force required when the plug assembly 500 is inserted into the socket assembly 100 is reduced, thereby reducing the difficulty of inserting the plug assembly 500 into the socket assembly 100.

[0056] Furthermore, the plug assembly 500 also includes a lubricating layer, which is arranged on the inclined surface. When the pusher 530 is inserted into the plug slot 111, the inclined surface 531 of the pusher 530 pushes the abutment 330 to compress the elastic element 310. At this time, the lubricating layer lubricates the inclined surface 531 and the abutment 330, reducing the friction between the inclined surface 531 and the abutment 330, making it easier for the inclined surface 531 to push the abutment 330 to compress the elastic element 310, thereby making it easier for the plug assembly 500 to be inserted into the socket assembly 100. It can be understood that the lubricating layer can be a paraffin layer structure, a lubricating oil layer structure, or other layer structures with lubrication functions in the prior art.

[0057] like Figure 7 and Figure 8 As shown, in one embodiment, the socket assembly 100 further includes a first wedge-shaped fixing member 150, which is connected to the slot wall of the plug slot 111 adjacent to the outer side of the plug body 510, and the first wedge-shaped fixing member 150 is staggered with the pushing member 530. The plug assembly 500 further includes a second wedge-shaped fixing member 550, which is protrudingly connected to the outer side of the plug body 510, and the second wedge-shaped fixing member 550 is staggered with the pushing member 530, and the first wedge-shaped fixing member 150 and the second wedge-shaped fixing member 550 are in abutment with each other. After the plug assembly 500 is inserted into the socket assembly 100, the plug assembly 500 is fixed by the elastic limiting assembly 300. In order to improve the stability of the plug assembly 500 in the socket assembly 100, in the present embodiment, after the plug assembly 500 is inserted into the socket assembly 100, the first wedge-shaped fixing member 150 abuts against the second wedge-shaped fixing member 550 to fix the plug assembly 500, thereby improving the stability of the plug assembly 500.

[0058] Furthermore, the mounting seat 110 of the socket assembly 100 is also provided with an avoidance groove, which is connected to the guide groove 111a. In this embodiment, when the plug assembly 500 is inserted into the socket assembly 100, the first wedge-shaped fixing member 150 passes through the avoidance groove and abuts against the second wedge-shaped fixing member 550, thereby avoiding the problem that the first wedge-shaped fixing member 150 hits the mounting seat 110 of the socket assembly 100 and ensuring that the first wedge-shaped fixing member 150 and the second wedge-shaped fixing member 550 abut against each other.

[0059] Further, the socket assembly 100 further includes a first adjusting member 170, which is respectively connected to the slot wall of the plug slot 111 adjacent to the outer side of the plug body 510 and the first wedge fixing member 150, and the first wedge fixing member 150 pushes the first adjusting member 170 to compress when it abuts against the second wedge fixing member 550. However, in actual use environment, the plug assembly 500 may have different specifications. In order to make the socket assembly 100 adapt to plug assemblies 500 of different specifications, further, the slot wall of the plug slot 111 adjacent to the outer side of the plug body 510 is connected to the first wedge fixing member 150 through the first adjusting member 170. When the plug assembly 500 is inserted into the socket assembly 100, the first wedge-shaped fixing member 150 and the second wedge-shaped fixing member 550 abut against each other, so that the first wedge-shaped fixing member 150 pushes the first adjusting member 170 to compress, thereby preventing the first wedge-shaped fixing member 150 from blocking the insertion movement of the plug assembly 500, thereby enabling plug assemblies 500 of different specifications to be inserted into the socket assembly 100, so that the socket assembly 100 is adapted to plug assemblies 500 of different specifications, thereby improving the versatility and adaptability of the socket assembly 100. In this way, while ensuring that plug assemblies 500 of different specifications are inserted into the socket assembly 100, the first wedge-shaped fixing member 150 and the second wedge-shaped fixing member 550 abut against each other, so as to improve the stability of the plug assembly 500. It can be understood that the first adjusting member 170 can be selected from springs, silicone or other elastic structures.

[0060] In one embodiment, the plug assembly 500 further includes a second adjusting member 570, which is connected to the plug body 510 and the second wedge fixing member 550 respectively, and the second wedge fixing member 550 pushes the second adjusting member 570 to be compressed when it abuts against the first wedge fixing member 150. However, the socket assembly 100 has different specifications. In order to make the plug assembly 500 adapt to the socket assembly 100 of different specifications, further, the plug body 510 is fixedly connected to the second wedge fixing member 550 through the second adjusting member 570. When the plug assembly 500 is inserted into the socket assembly 100, the first wedge-shaped fixing member 150 abuts against the second wedge-shaped fixing member 550, so that the second wedge-shaped fixing member 550 pushes the second adjusting member 570 to compress, thereby preventing the second wedge-shaped fixing member 550 from blocking the insertion movement of the plug assembly 500, thereby enabling the plug assembly 500 to be inserted into socket assemblies 100 of different specifications, so that the plug assembly 500 is adapted to socket assemblies 100 of different specifications, thereby improving the versatility and adaptability of the plug assembly 500. In this way, while ensuring that the plug assembly 500 is inserted into socket assemblies 100 of different specifications, the first wedge-shaped fixing member 150 and the second wedge-shaped fixing member 550 abut against each other, so as to improve the stability of the plug assembly 500. It can be understood that the second adjusting member 570 can be selected from springs, silicone or other elastic structures.

[0061] In one embodiment, the socket assembly 100 further includes a first guide post 190, which is connected to the slot wall of the plug slot 111 adjacent to the outer side of the plug body 510, and the first wedge-shaped fixing member 150 is provided with a first guide hole 151, and the first guide post 190 is movably inserted in the first guide hole 151. When the first wedge-shaped fixing member 150 pushes the first adjusting member 170 to be compressed, the first wedge-shaped fixing member 150 moves along the first guide post 190 toward the slot wall of the plug slot 111. In this way, the first guide post 190 guides the movement of the first wedge-shaped fixing member 150 to prevent the first wedge-shaped fixing member from deviating during the movement, thereby ensuring that the first wedge-shaped fixing member 150 and the second wedge-shaped fixing member 550 are in contact with each other. Furthermore, the first guide post 190 is inserted into the first adjusting member 170, so that the structure of the socket assembly 100 is compact and the space utilization rate of the socket assembly 100 is improved.

[0062] Furthermore, the plug assembly 500 further includes a second guide post 590, which is connected to the plug body 510, and the second wedge-shaped fixing member 550 is provided with a second guide hole 551, and the second guide post 590 is movably inserted in the second guide hole 551. When the second wedge-shaped fixing member 550 pushes the second adjusting member 570 to be compressed, the second wedge-shaped fixing member 550 moves along the second guide post 590 toward the direction close to the plug body 510, so that the second guide post 590 guides the movement of the second wedge-shaped fixing member 550 to prevent the second wedge-shaped fixing member 550 from being offset during the movement, thereby ensuring that the first wedge-shaped fixing member 150 and the second wedge-shaped fixing member 550 are in contact with each other. Furthermore, the second guide post 590 is inserted into the second adjusting member 570, so that the structure of the socket assembly 100 is compact, and the space utilization rate of the socket assembly 100 is improved.

Further, the connection structure includes a socket assembly 100, an elastic limit assembly 300 and a plug assembly 500, wherein the socket assembly 100 includes a mounting seat 110, wherein the mounting seat 110 is provided with a plug slot 111 and a mounting hole 113 that are interconnected. One end of the elastic limit assembly 300 is installed in the mounting hole 113, and the other end of the elastic limit assembly 300 protrudes from the plug slot 111. The plug assembly 500 includes a plug body 510 and a push member 530, wherein the push member 530 protrudes and is connected to the outside of the plug body 510. The plug body 510 and the pusher 530 are both inserted into the insertion slot 111, and the elastic limiting assembly 300 is used to protrude into the insertion slot 111 when the plug body 510 and the pusher 530 are inserted into the insertion slot 111, so that the pusher 530 is limited in the insertion slot 111. The pusher 530 is used to abut against and push the elastic limiting assembly 300 to contract when plugged into or pulled out of the insertion slot 111, and there is an angle between the direction in which the pusher 530 is plugged into or pulled out of the insertion slot 111 and the elastic expansion and contraction direction of the elastic limiting assembly 300.

[0064] The present application also provides a sofa, comprising a sofa body and the power supply device described in the above embodiment, wherein the mounting seat 110 is mounted on the sofa body. Furthermore, the connection structure comprises a socket assembly 100, an elastic limiting assembly 300 and a plug assembly 500, wherein the socket assembly 100 comprises a mounting seat 110, wherein the mounting seat 110 is provided with a plug slot 111 and a mounting hole 113 that are interconnected. One end of the elastic limiting assembly 300 is mounted in the mounting hole 113, and the other end of the elastic limiting assembly 300 protrudes from the plug slot 111. The plug assembly 500 comprises a plug body 510 and a pusher 530, wherein the pusher 530 protrudes and is connected to the outside of the plug body 510. The plug body 510 and the pusher 530 are both inserted into the insertion slot 111, and the elastic limiting assembly 300 is used to protrude into the insertion slot 111 when the plug body 510 and the pusher 530 are inserted into the insertion slot 111, so that the pusher 530 is limited in the insertion slot 111. The pusher 530 is used to abut against and push the elastic limiting assembly 300 to contract when plugged into or pulled out of the insertion slot 111, and there is an angle between the direction in which the pusher 530 is plugged into or pulled out of the insertion slot 111 and the elastic expansion and contraction direction of the elastic limiting assembly 300.

[0065] Compared with the prior art, the present invention has at least the following advantages:

[0066] After the plug body 510 and the pushing member 530 are inserted into the plug-in slot 111, the elastic limiting assembly 300 protrudes from the plug-in slot 111, so that the pushing member 530 is limited in the plug-in slot 111, and there is an angle between the direction in which the pushing member 530 is inserted and pulled out of the plug-in slot 111 and the extension and contraction direction of the elastic limiting assembly 300, so that only a part of the force for pulling out the plug body 510 and the pushing member 530 is used to push the elastic limiting assembly 300 to compress, so that when pulling out the plug body 510 and the pushing member 530, a larger force is required to compress the elastic limiting assembly 300 and leave the movement path of the pushing member 530, so that the force required to pull out the plug assembly 500 is larger, thereby improving the connection reliability between the plug assembly 500 and the socket assembly 100, and avoiding the problem of accidental separation of the plug assembly 500 and the socket assembly 100.
