Description

Technical Field

[0001] This invention relates to the field of electrical equipment technology, and in particular to a smart socket with a charging interface. Background Technology

[0002] In smart grid scenarios, some smart sockets can be linked with the power grid system to realize basic intelligent management and control functions such as load monitoring, energy consumption statistics, and remote on / off control. They are adapted to the core requirements of smart grids for "efficient power use, precise management and control, and energy saving and consumption reduction". They solve the problems of traditional ordinary sockets having single functions and being unable to adapt to multi-device charging and basic intelligent power management. Existing smart sockets are important power terminal devices at the end of the smart grid. Their core purpose is to provide stable mains power access for various power devices such as traditional home appliances and digital products. At the same time, they integrate charging interfaces such as USB and USB-C to realize convenient charging of lithium batteries of mobile devices such as mobile phones and tablets. They are widely used in desktop power use scenarios such as homes and offices.

[0003] However, existing smart sockets still have the following problems that need to be addressed:

[0004] Most existing smart sockets are either freestanding desktop sockets or fixed recessed sockets. Desktop smart sockets are further divided into concealed vertical sockets and non-concealed ones. Concealed vertical sockets mostly use electric drive to achieve height adjustment, which is not only complex in structure and high in manufacturing cost, but also relies on external power. The height of the socket cannot be adjusted when the power is off. Some height-adjustable sockets without electric drive lack a locking mechanism, so they cannot be fixed at the specified height after being raised or lowered, and are prone to slipping due to gravity or accidental contact. They cannot be adjusted according to the needs of user devices, such as chargers of different heights or electrical devices of different sizes, resulting in poor adaptability. Moreover, the power cord of concealed vertical sockets is mostly designed with a fixed length or lacks a dedicated winding mechanism. During installation, the excess power cord is exposed under the desktop. When the concealed vertical socket is raised or lowered, the power cord will also move, which can easily lead to safety hazards such as leakage and short circuit due to the pulling of the power cord. Summary of the Invention

[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0037] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0038] Example 1, referring to Figures 1-6This is the first embodiment of the present invention. This embodiment provides a smart socket with a charging interface, including a mounting cylinder 1. A socket housing 4 is slidably connected inside the mounting cylinder 1. The side walls of the socket housing 4 and the bottom cover 44 are integrally formed with protrusions. The cylinder cover 3 is fixed on the top surface of the mounting cylinder 1. The top surface of the cylinder cover 3 has a groove and a through groove that adapts to the socket housing 4. The protrusion is slidably connected in the groove. A fixing ring 2 is threadedly connected to the top side wall of the mounting cylinder 1. When the socket housing 4 is pulled out from the mounting cylinder 1, the protrusion slides axially in a straight line along the groove of the cylinder cover 3. The through groove provides a lifting channel for the socket housing 4.

[0039] During installation, the mounting cylinder 1 is inserted into the pre-drilled hole in the desktop, and the retaining ring 2 is fitted onto the mounting cylinder 1 from the bottom and screwed onto the top of the mounting cylinder 1 by threads, clamping it in the hole in the desktop, so that the socket housing 4 is fixed to the desktop as a whole.

[0040] The socket housing 4 has a socket panel 41 installed on its side wall. The socket panel 41 integrates a USB interface 42 and a USB-C interface 43. After the socket housing 4 is pulled out, the socket panel 41 is exposed. The mains power interface supplies power to traditional electrical appliances, while the USB interface 42 and USB-C interface 43 charge the lithium batteries of digital devices such as mobile phones. The interfaces are connected to the power supply circuit inside the socket housing 4, meeting the power and charging needs of multiple devices, thus adapting to modern desktop power usage scenarios.

[0041] A transmission assembly 7 is rotatably mounted on the side wall of the cylinder cover 3. The transmission assembly 7 is connected to the winding assembly 6. The first partition 11 is fixedly connected inside the mounting cylinder 1. The top of the first partition 11 is the lowest stroke position of the socket housing 4. At the same time, the first partition 11 divides the winding assembly 6 and the socket housing 4 into two working areas.

[0042] The take-up assembly 6 includes a conductive slip ring 66. The outer ring of the conductive slip ring 66 is fixedly mounted on the second partition 12 inside the mounting cylinder 1. The take-up assembly 6 includes a driven gear 61, a one-way transmission mechanism 63, and a take-up drum 65. The driven gear 61 is internally keyed to a first transmission shaft 62. The bottom end of the first transmission shaft 62 is internally keyed to the one-way transmission mechanism 63. The one-way transmission mechanism 63 is mounted in a rotating seat 64. The bottom end of the rotating seat 64 is fixedly connected to the inner ring of the conductive slip ring 66. The bottom of the inner ring of the conductive slip ring 66 is fixedly mounted to the take-up drum 65.

[0043] When the transmission component 7 rotates, it drives the driven gear 61 to rotate, and transmits the torque to the one-way transmission mechanism 63 through the first transmission shaft 62. The one-way transmission mechanism 63 transmits torque only in one direction of rotation, that is, when winding the wire, which drives the rotating seat 64 and the inner ring of the conductive slip ring 66 to rotate synchronously, thereby driving the take-up drum 65 to rotate. The rotation of the take-up drum 65 winds up the power supply wire 9 scattered outside the mounting drum 1 to adapt to different installation scenarios.

[0044] The outer ring of the conductive slip ring 66 is fixedly installed in the mounting shell on the bottom surface of the second partition plate 12, so that the outer ring can be fixed while the inner ring can rotate, so as to provide winding of the power supply line 9 without affecting the power transmission.

[0045] The one-way transmission mechanism 63 includes a ratchet 631 and a limiting tooth 632. The ratchet 631 is rotatably connected in a rotating groove 643 on the top surface of the rotating seat 64. A sliding groove 641 is provided on the side wall of the rotating groove 643. The limiting tooth 632 is pressed and installed in the sliding groove 641 by a second spring 633, and the limiting tooth 632 slides and meshes with the tooth groove on the side wall of the ratchet 631. A second transmission shaft 642 is fixed at the center of the bottom surface of the rotating seat 64. The second transmission shaft 642 is fixedly installed with the inner ring of the conductive slip ring 66.

[0046] When the first drive shaft 62 drives the ratchet 631 to rotate, that is, when the line is being taken in, the ratchet 631 teeth mesh with the limiting teeth 632, driving the rotating seat 64 to rotate. When the power supply line 9 on the take-up drum 65 is pulled out, the rotating seat 64 rotates in the opposite direction, the ratchet 631 teeth push open the limiting teeth 632, the limiting teeth 632 compress the second spring 633 and slide into the next tooth groove, so that the power supply line 9 of the required length can be pulled out from the mounting drum 1.

[0047] The transmission assembly 7 includes a first drive gear 71 and a drive rod 72. The bottom of the drive rod 72 is keyed to the first drive gear 71. The first drive gear 71 is meshed with the side wall of the driven gear 61. The top of the drive rod 72 is keyed to a second drive gear 74. The side wall of the drive rod 72 is rotatably mounted near the inner side wall of the mounting cylinder 1 via a bearing 73. The side wall of the second drive gear 74 is meshed with the inner side wall of the gear ring 75. The top surface of the gear ring 75 is fixedly connected to the rotating disk 76. Both the rotating disk 76 and the gear ring 75 are rotatably connected in an annular groove opened inside the cylinder cover 3.

[0048] In use, manually rotate the disc 76 on the top of the cylinder cover 3 to drive the gear ring 75 to rotate synchronously. The gear ring 75 meshes with the second drive gear 74, driving the second drive gear 74 and the drive rod 72 to rotate around the shaft seat 73. The first drive gear 71 at the bottom of the drive rod 72 meshes with the driven gear 61, transmitting the rotational torque to the driven gear 61 of the take-up assembly 6, thereby driving the take-up cylinder 65 to take up the line. This allows the excess power supply line 9 to be wound up simply by manually turning the disc 76.

[0049] Example 2, refer to Figures 7-8This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The bottom surface of the mounting cylinder 1 is equipped with a base plate 5. The bottom end of the take-up cylinder 65 is rotatably connected in the rotating hole opened in the center of the base plate 5 through a fixed shaft. When the take-up cylinder 65 rotates around the fixed shaft, it winds the power supply line 9 around the side wall. The bottom side wall of the mounting cylinder 1 is provided with a notch, through which the power supply line 9 passes. The notch provides an entry and exit channel for the power supply line 9.

[0050] The power supply line 9 is wound around the side wall of the take-up drum 65, and the power supply end of the power supply line 9 is electrically connected to the power supply end of the inner ring of the conductive slip ring 66. One end of the conductive component 10 is electrically connected to the outer ring outlet end of the conductive slip ring 66. A bottom cover 44 is installed on the bottom surface of the socket housing 4. The other end of the conductive component 10 slides against the elastic element 45 on the bottom cover 44. The conductive component 10 includes a conductive wire 101 and a conductive copper plate 103. One end of the conductive wire 101 is electrically connected to the power supply terminal on the outer ring of the conductive slip ring 66. The conductive wire 101 is installed along the groove opened on the inner side wall of the mounting cylinder 1. The conductor 102 inside the other end of the conductive wire 101 is fixedly installed on the bottom surface of the cylinder cover 3 by the wire clamp 104. The free ends of the two conductors 102 are welded to the conductive copper plate 103. The conductive copper plate 103 is vertically installed on the inner side wall of the mounting cylinder 1.

[0051] By using conductive wire 101 in conjunction with conductive copper plate 103, the power supply terminal of socket housing 4 is changed from the existing method of directly connecting to socket housing 4 via wire 102 to power supply via elastic element 45 when socket housing 4 is raised. When not in use, socket housing 4 is fully inserted into mounting cylinder 1, and elastic element 45 is separated from conductive copper plate 103, thereby cutting off the power supply to the inside of socket housing 4 and realizing the power cut-off of socket housing 4.

[0052] The elastic element 45 includes a conductive contact 451, which is slidably mounted on the two side walls of the protrusion. A relief groove is provided inside the protrusion. The limiting plate of the conductive contact 451 is pressed and mounted in the relief groove by the first spring 452. The relief groove provides the conductive contact 451 with extension and retraction space. The limiting plate restricts the extension and retraction stroke of the conductive contact 451 to prevent the conductive contact 451 from falling out of the protrusion and to ensure contact stability.

[0053] The first spring 452 ensures the contact pressure between the contact and the copper plate. A wiring copper piece 453 is fixedly connected to the side wall of the limit plate. The wiring copper piece 453 is connected to the power supply device wire of the socket housing 4 through the wire.

[0054] When the socket housing 4 is raised and lowered, the conductive contact 451, under the push of the first spring 452, always elastically contacts and slides with the conductive copper plate 103, reducing incomplete contact and suppressing the generation of electric sparks. When the socket housing 4 is fully retracted, the contact moves down with the protrusion, separates from the copper plate and cuts off the power, realizing power-off storage and improving safety.

[0055] Example 3, referring to Figures 7-11 This is the third embodiment of the present invention. This embodiment is based on the first two embodiments. A guide plate 13 is fixedly connected to the inner side wall of the mounting cylinder 1. A wave groove 8 is opened on the inner side wall of the guide plate 13. A limiting component 14 is slidably connected to the bottom cover 44. The limiting component 14 is slidably connected to the wave groove 8 on the guide plate 13. A locking component 15 is installed on the top of the socket housing 4. The locking component 15 is slidably inserted into the limiting component 14.

[0056] When the socket housing 4 is needed, manually pull the socket housing 4 out of the mounting cylinder 1. The limiting component 14 slides along the wave groove 8 and engages with the trough of the wave groove 8 to lock the position. By operating the locking component 15, the engagement between the limiting component 14 and the wave groove 8 can be released, allowing the socket housing 4 to rise and fall freely. This achieves the desired height of the socket housing 4 protruding from the mounting cylinder 1. The amount of the socket housing 4 protruding from the mounting cylinder 1 can be selected according to the user's equipment requirements, enabling multi-position lifting without electricity and without the need for a motor drive.

[0057] The limiting component 14 includes a locking tongue 141 and a third spring 143. A rectangular groove is provided inside the bottom cover 44. The limiting frame of the locking tongue 141 is slidably connected to both ends of the rectangular groove. A fixing block 144 is fixed in the middle of the rectangular groove. The third spring 143 is pressed and installed between the fixing block 144 and the locking tongue 141 to ensure that the locking tongue 141 is continuously engaged with the wave groove 8, realizing passive self-locking. The position can be fixed without additional operation. The end face of the locking tongue 141 is arc-shaped. The locking tongue 141 is locked in the wave groove 8. The arc-shaped surface reduces the frictional resistance during lifting and lowering, making the lifting and lowering operation smooth, while preventing the locking tongue 141 from jamming.

[0058] The rectangular groove and the limiting frame are used to limit the lateral sliding stroke of the locking tongue 141 and prevent the locking tongue 141 from dislodging.

[0059] When the socket housing 4 is manually pulled up, the arc surface of the locking tongue 141 is squeezed by the crest of the wave groove 8, compressing the third spring 143 to retract into the rectangular groove. After sliding past the crest, the third spring 143 pushes the locking tongue 141 out and locks into the next trough. When the socket housing 4 is lowered, the locking tongue 141 slides along the arc surface of the wave groove 8 and locks into the corresponding trough to achieve low-position locking.

[0060] The locking assembly 15 includes a moving rod 151 and a moving frame 152. A limiting hole 142 is provided on the top surface of the locking tongue 141. The bottom end of the moving rod 151 is inserted into the limiting hole 142. The top end of the moving rod 151 is fixedly connected to the moving frame 152. An inclined groove 1521 is provided inside the moving frame 152. The moving frame 152 and the moving rod 151 move vertically on the top of the socket housing 4. A fourth spring 153 is provided at the top end of the moving frame 152.

[0061] When the movable frame 152 moves downward under the push of the inclined groove 1521, it drives the movable rod 151 to move downward synchronously and insert into the locking hole 142 of the locking tongue 141, so that the locking tongue 141 cannot be retracted and remains in the low-level engagement state with the wave groove 8. At this time, the height between the socket housing 4 and the mounting cylinder 1 is limited to prevent the socket housing 4 from being accidentally pressed into the mounting cylinder 1 during the use of the socket housing 4.

[0062] A plug rod 154 is slidably connected to the top of the socket housing 4. One end of the plug rod 154 is slidably connected in the inclined groove 1521, and the other end of the plug rod 154 is fixed with a pressing plate 155. A plug plate is integrally formed in the middle of the pressing plate 155. A square groove 157 is opened in the top of the socket housing 4. A fifth spring 156 is installed in the square groove 157, and the plug plate is slidably connected in the square groove 157.

[0063] When it is necessary to pull out the socket housing 4 of the mounting cylinder 1, the user pinches the press plate 155 on the top side wall of the socket housing 4 with his / her fingers, so that the press plate 155 drives the plug rod 154 to move towards the moving frame 152. The end of the plug rod 154 slides along the inclined groove 1521, pushing the moving frame 152 to move upward, thereby causing the moving rod 151 to move upward and be pulled out from the limiting hole 142 of the locking tongue 141, unlocking the limiting component 14, releasing the press plate 155, the fifth spring 156 rebounds, pushing the plug plate, the press plate 155, and the plug rod 154 to reset.
