Description

Technical Field

[0001] The invention relates to the technical field of sockets, and in particular to a socket capable of rotating and switching modes, and an electric vehicle charging system. Background Art

[0002] With the rapid development of society and the popularization of smart home and new energy concepts, sockets, as key components for power distribution and electrical appliance connection, are increasingly becoming the focus of consumer attention for their safety, convenience, and intelligence. Traditional sockets mainly meet basic power access needs, but they have obvious limitations in the following aspects: 1. The compatibility is relatively low, and each socket of traditional sockets often only supports a single mode. 2. The design is not user-friendly, and the spacing between sockets of various modes is small, which is not only difficult to plug and unplug, but also occupies a large space. 3. Sockets with multiple modes have high material costs and waste of resources because the sockets support a single mode. For example, the Chinese invention with application number CN201910442994.5 discloses an environmentally friendly socket, which is provided with a module with a straight-line socket, and the function of the socket is adjusted by rotating the module. The straight-line socket meets national safety standards, which improves the safety performance of environmentally friendly sockets. The mode switching of the environmentally friendly socket is achieved by manually toggling the toggle plate. The movement of the toggle plate drives the second cylindrical module and the third cylindrical module to rotate through the cooperation of the rack plate and the follower gear, thereby adjusting the angle of the live wire socket and the neutral wire socket to achieve the switching between the two-pin state and the three-pin state. The Chinese utility model with application number CN201320845037.5 discloses a simple rotary multifunctional socket, which drives the extension rod to move by pressing a button, and then realizes the rotation switching of the second socket hole through a spring-type automatic device. Specifically, when the button is pressed, the extension rod drives the movable rod to move, and the movable rod moves inward through the engagement of the boss teeth and the first teeth. At the same time, the second teeth on the extension rod engage with the teeth on the second socket hole, driving the second socket hole to rotate, and realizing the switching between the two-pin state and the three-pin state. When the button is released, the return force of the spring restores the device to the initial state. It can be seen that the existing solutions can already realize the switching between the two-pin state and the three-pin state, but the switching requires additional manual switching operations, which limits the user experience. The traditional automation method using motors for driving is complex, not only costly but also low in reliability.

[0046] The first spring bracket 10 is installed in the housing 1 at a position corresponding to the first jack 114, and a socket metal spring 5 is provided on the top of the first spring bracket 10;

[0047] A movable pressing block 2; an angled block 211 is provided on the movable pressing block 2 to convert pressure into a driving force for left-right movement; the angled block 211 is provided on the surface of the socket panel 11, and the bottom width is larger than the width of the first plug hole 114 and smaller than the width of the storage bin hole 111, and can move left-right between the first plug hole 114 and the storage bin hole 111; the first plug hole 114 is connected to the storage bin hole 111; the angled block 211 is at a certain angle to the horizontal, and when the metal plug of the ground wire of the three-pin plug 13 contacts and presses the angled block 211, the movable pressing plate will move horizontally to the right;

[0049] When static, the second sockets 43 of the two socket assemblies 4 are parallel to each other, matching the plugging and unplugging of the two-pin plug 12; when using the two-pin socket mode, the position and distance between the two second sockets 43 correspond to the position and distance of the two metal plugs of the plug; when using the three-pin socket mode, the position and distance between the two second sockets 43 and the first socket 114 correspond to the position and distance of the three metal plugs of the plug.

[0050] This solution is designed for a variety of industries, covering home appliances, electric vehicles, charging piles and industrial areas. It is suitable for a variety of socket modes, and the socket is very small, taking up little space, and the socket shell 1 is insulated, meeting the industrial grade long-term durability, multiple identical materials, high material utilization rate, and reducing costs. The design ratio is perfectly adapted to a variety of plugs, solving the problem of plugging and unplugging difficulties for users, and realizing quasi-automatic and non-sensing switching of usage modes, which improves the user experience while the solution is simple, reliable, and low-cost.

[0051] In specific implementation, Figure 5As shown, the movable pressure block 2 also includes a buckle plate 213 arranged under the socket panel 11, and the width of the buckle plate 213 is larger than the width of the storage bin hole 111 to prevent the movable pressure block 2 from popping out of the panel when it is completely in the storage bin hole 111; the buckle plate 213 is provided with a accommodating cavity, and the accommodating cavity corresponds to the position of the bevel block 211, and the tail of the buckle plate 213 is connected to the tail of the bevel block 211 to prevent interference when the first metal plug is inserted into the first plug hole 114; the tail of the buckle plate 213 is provided with a guide column through hole 212, which is used to limit the connection guide column 6.

[0052] Furthermore, the bevel block 211 has ribs on both sides of the bevel to form a groove, so that the ground wire metal plug of the three-pin plug 13 can be stably pressed on the bevel block 211 and can only slide relative to the bevel block 211 left and right.

[0053] In specific implementation, Figure 2 As shown, the linkage assembly includes a sliding plate 9, a Y-axis spring 8, a Z-axis spring 7 and two guide pillars 6; Figure 4 As shown, a rack 91 is provided on the first side of the sliding plate 9 and connected to the gear 421 at the bottom of the jack assembly 4 to enable it to rotate; two guide column sleeves 92 are provided on both sides of the sliding plate 9 and matched with the bottoms of the two guide columns 6; a spring pressing groove 93 is provided on the second side of the sliding plate 9; the Y-axis spring 8 is located between the spring pressing groove 93 and the wall of the shell 1 to provide a restoring elastic force for the sliding plate 9 after the sliding plate 9 moves to the right, and at the same time, the Y-axis spring 8 is limited by the spring pressing groove 93; the guide column 6 is connected to the buckle plate 213 through the guide column through hole 212; the Z-axis spring 7 is sleeved on the guide column 6 and is located between the sliding plate 9 and the buckle plate 213.

[0054] In specific implementation, Figure 2 , Figure 3 As shown, the jack assembly 4 includes a jack seat 42 and a jack end cover 41; the jack end cover 41 is installed on the jack seat 42 and forms a second jack 43 with the jack seat 42; a rotating sleeve 3 is also provided between the jack end cover 41 and the sleeve matching hole 112; a gear 421 is provided at the bottom of the jack seat 42 and is connected to the rack 91, and the rotation of the jack seat 42 drives the entire jack assembly 4 to rotate under the drive of the rack 91.

[0055] Furthermore, the jack seat 42 and the jack end cover 41 are of cylindrical structure; the outer side surface of the bottom of the jack seat 42 is provided with a toothed structure to form a gear 421 meshing with the rack 91.

[0056] Furthermore, the jack seat 42 has a first spring clip cavity; the jack end cover 41 has a square groove for inserting a metal insert of a plug; the square groove is connected to the first spring clip cavity to form a second jack 43, and the socket metal spring clip 5 is disposed in the first spring clip cavity, with the opening of the socket metal spring clip 5 facing upward.

[0057] Furthermore, a wiring port communicating with the first spring cavity is provided on the side of the socket seat 42 , so that the wire can enter the first spring cavity from the wiring port and connect with the socket metal spring 5 .

[0058] Furthermore, the bottom end of the jack seat 42 is provided with a rotating sleeve 3, and the bottom surface of the housing 1 is provided with a corresponding rotating shaft; the rotating sleeve 3 of the jack seat 42 can be rotatably inserted on the rotating shaft, so that the jack seat 42 can rotate around the rotating shaft under the drive of the rack 91. Furthermore, the height of the rotating shaft is slightly greater than the depth of the rotating sleeve 3, so that the bottom end of the jack seat 42 is slightly separated from the bottom surface of the housing 1 and does not contact, which can reduce the friction resistance of the jack seat 42 when it rotates, and avoid excessive interaction when the jack seat 42 is rotated under force.

[0059] The socket panel 11 is provided with a storage bin hole 111, the purpose of which is to provide a large enough placement space for the bevel block 211 of the movable pressing block 2. The socket panel 11 is provided with two sleeve matching holes 112, which can be used to install the rotating sleeve 3, so that the friction force is reduced when the socket assembly 4 rotates.

[0060] In specific implementation, Figure 2 , Fig.13 As shown, it also includes a baffle 15 component; a slide groove 113 connected to the first socket 114 is provided on the socket panel 11; the baffle 15 component can be telescopically installed up and down in the shell 1 and extend out of the socket panel 11 through the slide groove 113, so that the baffle 15 component can slide up and down in the slide groove 113.

[0061] Furthermore, the baffle 15 assembly includes a baffle spring 14, a baffle 15 and a support member 16; a sleeve shaft is provided in the middle of the lower part of the baffle 15; the upper part of the baffle spring 14 is sleeved on the sleeve shaft, and the lower end is connected to the mounting groove provided on the support member 16; the two sides of the support member 16 are respectively connected to the side walls of the shell 1; limiting bosses are respectively provided on both sides of the lower part of the baffle 15; the width distance of the limiting bosses on both sides is greater than the length of the slide groove 113, and the baffle 15 can slide up and down in the slide groove 113 without falling off the socket panel 11.

[0062] like Figure 7As shown, it is a schematic diagram of the internal structure of the socket. The guide post through hole 212 of the movable pressure block 2 is sleeved on the two guide posts 6, and is connected to the guide post sleeve 92 of the sliding plate 9 through the two guide posts 6. A Z-axis spring 7 is sleeved on each of the two guide posts 6, so that when the movable pressure block 2 is under pressure above the storage bin hole 111, it can be pressed down because there is no support from the socket panel 11. When there is no pressure, the Z-axis spring 7 opens, and the movable pressure block 2 can return to its initial state. At the same time, it cannot bounce off the socket panel 11 due to the limiting effect of the buckle plate 213. Figure 8 As shown, the sliding plate 9 is installed on the bottom plate of the housing 1 through a guide groove, and the Y-axis spring 8 is also installed on the bottom plate of the housing 1 (a spring tube is provided on the right end side of the housing 1, and the right end of the Y-axis spring 8 is installed in the spring tube); the left end of the Y-axis spring 8 is installed in the spring pressure groove 93, and is constrained and limited by the spring pressure groove 93. At the same time, the left end of the spring tube is also located in the spring pressure groove 93, so that the sliding plate 9 can reciprocate in the horizontal direction. In addition, the first spring clip bracket 10 is fixed on the bottom plate of the housing 1, so the rack 91 of the sliding plate 9 passes through the first spring clip bracket 10 and is connected to the jack assembly 4, so that the sliding stroke of the sliding plate 9 in the horizontal direction is the distance between the first spring clip bracket 10 and the right end side of the bottom plate of the housing 1. At the same time, the first spring clip bracket 10 also limits the vertical movement of the sliding plate 9, playing a role in stabilizing the sliding plate 9. The two jack assemblies 4 are distributed on both sides of the rack 91 of the sliding plate 9. The gear 421 of the jack assembly 4 cooperates with the rack 91. When the rack 91 slides, the two gears 421 rotate at the same time, and the rotation directions are opposite. When static, the Y-axis spring 8 is opened, and the sliding plate 9 is tightly attached to the first spring bracket 10. When the force is applied, the Y-axis spring 8 is compressed, and the sliding plate 9 slides to the right side of the bottom plate of the housing 1 until it is tightly attached, and the two jack assemblies 4 rotate in opposite directions to a certain angle to meet the live and neutral line insertion angles of the three-pin plug 13.

[0063] like Fig. 9 , Fig.10 The figure shows the state of inserting the two-pin plug 12, the two jack components 4 of the socket are in a parallel state, and the two metal sheets of the two-pin plug 12 are respectively inserted into the second jack 43. At this time, the movable pressing block 2 is not subjected to force, the bevel block 211 covers the first jack 114, the jack component 4 will not rotate, and the socket remains static. This situation is suitable for plugging in a two-pin plug.

[0064] like Fig.11 , Fig.12 , Fig.13The figure shows the state of inserting the three-pin plug 13. When the three-pin plug 13 is inserted into the socket, the first metal sheet 1311 (ground wire metal sheet) of the three-pin plug 13 first contacts the bevel block 211 of the movable pressing block 2. When the three-pin plug 13 continues to be inserted downward, the movable pressing block 2 is subjected to force and moves horizontally to the right at the same time. Since the movable slider is connected to the sliding block, the sliding block moves horizontally to the right at this time, the Y-axis spring 8 is also squeezed, and the two rotating jack components 4 rotate in opposite directions. When the second and third metal sheets 1313 of the three-pin plug 13 are flush with the upper surface of the socket panel 11, that is, the first metal sheet 1311 of the three-pin plug 13 has completely squeezed the bevel block 211 of the movable pressing block 2, so that the bevel block 211 completely leaves the first jack 114 area and completely enters the storage bin hole 111 area, at this time, the movable pressing block 2 and the sliding plate 9 stop moving, and the two jack components 4 rotate to the angle where the second and third metal sheets 1313 can be inserted. That is, the three sockets of the socket meet the plugging conditions of the three-pin plug 13. Continue to plug the three-pin plug 13 downward, and the first metal sheet 1311, the second metal sheet 1312 and the third metal sheet 1313 can all contact with the socket metal spring sheet 5, satisfying the use function of the plug and the socket. When the bottom surface of the three-pin plug 13 is in close contact with the upper surface of the bevel block 211, the plug can be inserted downward, because the socket panel 11 is provided with a storage compartment hole 111, and the bevel block 211 will shrink into the storage compartment hole 111 after being subjected to pressure, until the bottom surface of the three-pin plug 13 is in close contact with the upper surface of the socket panel 11.

[0065] The three-pin plug 13 is pulled out of the socket. When the plug is pulled out to a certain height, due to the action of the Z-axis spring 7, the movable pressure block 2 is also ejected to a certain height synchronously until it is fully ejected. At this time, the second and third metal sheets 1313 of the three-pin plug 13 are still in the socket, so the movable pressure block 2 is resisted and cannot move horizontally to the left. When the plug is fully pulled out, the Y-axis spring 8 will slowly recover, and the sliding plate 9 and the movable pressure block 2 will move horizontally synchronously until they reach the initial state.

[0066] Furthermore, the lower surface edge of the bevel block 211 near the first metal insert is chamfered. If the elastic force of the Z-axis spring 7 weakens and the upward pop-up height decreases, the bevel block 211 can still return to the position of the first socket 114 under the guidance of the chamfer, thereby increasing the reliability of the socket.

[0067] The structure of this solution has the following advantages:

[0068] 1. The structure of this solution is highly flexible, can be adapted to a wide range of occasions, can share parts, and reduce product development and manufacturing costs.

[0069] 2. Due to its simple structure, compact size and very small footprint, it is suitable for installation in a variety of working conditions and has low design, manufacturing and use costs.

[0070] 3. The overall protection strength of the socket is high, and the outer surface is insulated and fireproof, providing protection for the safety of users.

[0071] 4. This structure is easy to install on the equipment and can be completed in just a few steps, which can greatly improve production efficiency.

[0072] 5. This design is flexible and the jack position is reasonable, which solves the difficulty of plugging and unplugging, adapts to the senseless switching of the two modes, and provides convenience for users.
