[0021] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0022] In the description of the present invention, if there is a description of first and second, it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0023] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0024] Reference Figures 1 to 8 The present invention discloses a plug connection mechanism, including a charging seat 100, a basic pin 200, an adapter body 300, an adapter pin 400, a locking member 500 and a conductive component 600. The charging seat 100 is provided with a groove 110, a partition block 120 is provided in the groove 110, and the partition block 120 divides the groove 110 into two slots 111. A bayonet 130 is provided at the bottom of the groove 110, and the bayonet 130 is provided in front of the partition block 120; the basic pin 200 is provided with two pieces, and the two pieces of the basic pin 200 are hinged on the charging seat 100, and the basic pin 200 is configured to enter or move away from the corresponding slot 111 by swinging.

[0025] Reference Figures 1 to 4The adapter body 300 has an adapter block 310 protruding from the lower end thereof, and the adapter block 310 is provided with an avoidance groove 320 extending in the front-to-back direction, and the avoidance groove 320 divides the adapter block 310 into two receiving parts 330, and the receiving parts 330 are provided with receiving holes 340, the adapter block 310 is configured to be inserted into the groove 110, the avoidance groove 320 is configured to accommodate the partition block 120, and the receiving parts 330 are configured to be inserted into the basic pin 200; the adapter pin 400 is connected to the upper end of the adapter body 300; the locking member 500 is arranged on the adapter block 310, and the locking member 500 is used to connect the bayonet 130 to lock the adapter body 300 and the charging base 100; the conductive component 600 is arranged in the adapter body 300, one end of the conductive component 600 is electrically connected to the adapter pin 400, and the other end of the conductive component 600 extends to the receiving socket 340, and the other end of the conductive component 600 is used to electrically connect to the basic pin 200.

[0026] It should be understood that the bayonet 130 is set at the bottom of the groove 110. After the base pin 200 is inserted into the socket 340, the force point of the socket 340 and the force point of the locking member 500 are not in the same plane, so that the force area and force space of the adapter block 310 and the slot 111 are larger, and the adapter block 310 and the slot 111 are more tightly connected to avoid the connection between the charging seat 100 and the adapter body 300 from breaking. In addition, the plug connection mechanism has a simple structure, uses the locking member 500 for a snap-on lock, and the conductive component 600 is simply installed, so that the charging seat 100 and the adapter body 300 are convenient and quick to assemble, which is conducive to production. Because a snap-in 130 is provided at the bottom of the groove 110, the force point of the locking member 500 is at the bottom of the groove 110. Also, because the force point of the receiving socket 340 is on the upper inner wall of the receiving socket 340 (when the base pin is to be vertically separated from the receiving socket 340), this arrangement allows the force points to be vertically multiplexed, thereby improving the connection stability of the charging stand 100 and the adapter 300.

[0027] It is understandable that when plugging a plug into a socket, it is often necessary to hold the plug and shake it while plugging it in, because the charging base 100 and the adapter body 300 are separate and are more sensitive to shaking. Therefore, the strength of the connection between the charging base 100 and the adapter body 300 must be sufficient to avoid the adapter block 310 of the adapter body 300 from being shaken and cracked, thereby increasing the service life of the charger; wherein the opposite sides of the adapter body 300 and the charging base 100 are in a docking state after connection, that is, the width of the adapter body 300 in the left and right direction is equal to the width of the charging base 100 in the left and right direction, which is to cooperate with the position design of the adapter block 310 and the bayonet 130, so that the connection between the charging base 100 and the adapter body 300 is more stable.

[0028] Both basic plug pins 200 can be folded. When the two basic plug pins 200 are folded up and away from the slot 111, the two basic plug pins 200 can be used as plugs to plug into a national standard double-hole socket.

[0029] In some embodiments, a stopper 121 is provided at one end of the partition block 120 near the bottom of the groove 110, and a positioning step 321 is provided in the avoidance groove 320. The portion of the avoidance groove 320 located below the positioning step 321 is expanded from top to bottom. When the partition block 120 is inserted into the avoidance groove 320, the stopper 121 clamps the positioning step 321. The set stopper 121 provides an additional fulcrum to enhance the connection stability between the adapter block 310 and the slot 111. It can be understood that the portion of the avoidance groove 320 located below the positioning step 321 is expanded from top to bottom. This is to make the inserted portion 330 and the partition block 120 present a certain left-right direction. The air gap between the two basic pins 200 is increased to enhance the resistance between them, so as to avoid the accumulation of conductive materials in the avoidance groove 320 due to long-term use, thereby preventing the charger from being burned due to a short circuit. Because the charging stand 100 and the adapter 300 are separately arranged and often need to be used in plugging and unplugging situations, some moist conductive materials are easily accumulated over time. Also, because the charging stand 100 and the adapter 300 themselves are made of plastics such as PP or PVC, dewdrops are easily formed in the avoidance groove 320 when encountering weather such as the return of the south wind in the south. Therefore, the avoidance groove 320 is expanded to isolate the air between the two basic pins 200 and reduce the risk of conductive short circuit.

[0030] Reference Figures 2 to 4 The adapter body 300 includes a first shell 300a and a second shell 300b. The lower end of the first shell 300a is provided with an adapter shell 310a. The front end of the second shell 300b is provided with a cover 310b downwardly. The first shell 300a is snap-connected to the second shell 300b, so that the cover 310b encapsulates the front end opening of the adapter shell 310a to form an adapter block 310. The avoidance groove 320 is provided on the adapter shell 310a. The avoidance groove 320 separates the adapter shell 310a into two receiving parts 330. The receiving hole 340 on the receiving part 330 is connected to the inner cavity of the adapter shell 310a. The conductive component 600 is provided in the first shell 300a. The first shell 300a and the second shell 300b are snap-fitted to form the adapter body 300. The cover 310b and the adapter shell 310a form the adapter block 310. The structure is simple and the installation is convenient.

[0031] It should be understood that the connection method between the adapter body 300 and the charging base 100 is consistent, but the adapter pin 400 on the adapter body 300 needs to be set according to specific standards, such as setting the adapter pin 400 of British standard, American standard or European standard. The purpose is to replace the adapter body 300 and obtain adapter pins 400 of different specifications for easy use.

[0032] In some embodiments, a waist-shaped hole 310c is provided on the cover 310b, and the length of the waist-shaped hole 310c extends vertically. A sliding hole 310d is provided at the lower end of the adapter shell 310a. The locking component 500 includes a locking tongue 510 and a driving rod 520. The locking tongue 510 and the driving rod 520 are integrally formed. The locking tongue 510 is slidably connected in the adapter shell 310a, and the driving rod 520 protrudes out of the waist-shaped hole 310c. The locking tongue 510 is connected to the second shell 300b through an elastic member 530. The elastic member 530 is used to drive the locking tongue 510 to protrude out of the adapter shell 310a along the sliding hole 310d. The locking tongue 510 is configured to be inserted into the bayonet 130, and the driving rod 520 is used to drive the locking tongue 510 to retract into the adapter shell 310a along the sliding hole 310d. The locking component 500 has a simple structure and eliminates complex transmission. The locking tongue 510 can be operated by operating the driving rod 520, which is simple and convenient to operate.

[0033] It is understandable that the specific structural setting of the adapter body 300 only includes two shells. The locking member 500, elastic member 530, elastic contact piece and adapter pin 400 set in the shell can all be assembled into the shell, and there is no welding or riveting in the shell to fix the locking member 500, elastic member 530, elastic contact piece and adapter pin 400. These components are all installed by interference fit or directly by embracing and pressing the two shells, which is more convenient in installation, and the structure is simple, easy to realize automation on the production line, and even manual installation is extremely convenient. The connection method of the adapter body 300 is consistent with that of the charging stand 100, but the adapter pin 400 on the adapter body 300 needs to be set according to specific standards, such as setting the adapter pin 400 of the British standard, the American standard or the European standard, in order to replace the adapter body 300 and obtain adapter pins 400 of different specifications for easy use.

[0034] Reference Figure 4 and Figure 5The conductive component 600 includes two elastic contact pieces, and the adapter pin 400 includes two legs 410. The elastic contact piece is provided with a first contact portion 610, a connecting portion 620 and a second contact portion 630. The first contact portion 610, the connecting portion 620 and the second contact portion 630 are integrally formed, and the connecting portion 620 is arranged between the first contact portion 610 and the second contact portion 630. The first contact portion 610 is arranged to be tilted upward, and the free end of the second contact portion 630 is provided with an arc-shaped guiding structure 631. The connecting portion 620 is connected in the first shell 300a, the first contact portion 610 is electrically connected to the corresponding leg 410, and the second contact portion 630 extends to the corresponding receiving hole 340. The arc-shaped guiding structure 631 is used to guide the basic pin 200 to be inserted into the receiving hole 340. The structural design of the elastic contact piece enables the first contact portion 610 and the second contact portion 630 to extend a longer space, and the second contact portion 630 can better contact the basic pin 200.

[0035] It should be noted that the arc-shaped guide structure 631 and the receiving socket 340 jointly define a smaller receiving space. Because the elastic contact piece is elastic, when the basic pin 200 is inserted into the receiving socket 340, the arc-shaped guide structure 631 can not only guide the basic pin 200 to enter, but also rely on the elasticity of the elastic contact piece to squeeze the basic pin 200 with vertical force, so that the basic pin 200 is in stable contact with the elastic contact piece, avoiding the change of the contact area between the elastic contact piece and the basic pin 200, and avoiding the generation of electric sparks. The first contact portion 610 is tilted upward so that the support leg 410 can maintain a certain contact elasticity with the first contact portion 610, thereby ensuring the contact stability between the first contact portion 610 and the support leg 410.

[0036] In some embodiments, the support leg 410 includes an external end 411 and an internal end 412. A connecting hole 611 is opened on the first contact portion 610. The internal end 412 is inserted into the connecting hole 611. The first contact portion 610 is directly plugged into the support leg 410, which is easy to assemble and improves assembly efficiency.

[0037] Reference Figure 4 and Figure 5 , and also includes a fixing plate 640, which is embedded in the first shell 300a, and the connecting part 620 is connected to the fixing plate 640. The fixing plate 640 is made of insulating material. The setting of the fixing plate 640 plays a fixed connection role, so that the elastic contact piece is fixed and maintains fixed stability.

[0038] In some embodiments, an auxiliary bending structure 641 is provided on the fixing plate 640, and the bending part of the second contact portion 630 and the connecting portion 620 abuts against the auxiliary bending structure 641. The auxiliary bending structure 641 is provided to facilitate manual adjustment from the receiving hole 340 after the elastic contact piece is deformed, without disassembling the first shell 300a and the second shell 300b, thereby facilitating operation.

[0039] A charger according to an embodiment of the second aspect of the present invention includes a plug connection mechanism according to the embodiment of the first aspect of the present invention, and also includes a PCB700. The PCB700 is arranged in a charging base 100. A charging interface 140 is arranged on the outer wall of the charging base 100. The charging interface 140 and the basic pin 200 are both electrically connected to the PCB700.

[0040] At least the following beneficial effects are achieved: This charger has all the beneficial effects brought by the above-mentioned plug connection mechanism, which will not be described repeatedly here.

[0041] In some embodiments, a charging connection component 800 is also included. A magnetic block 900 is provided in both the charging seat 100 and the charging connection component 800. The magnetic block 900 is used to adsorb the charging seat 100 and the charging connection component 800. The charging connection component 800 is configured to be electrically connected to the PCB 700. It should be noted that the charging connection component 800 can be a retractable wire module or a wireless charging module. When the charging connection component 800 is a retractable wire module, a charging wire is wound inside the module. When in use, one end of the charging wire can be pulled out and plugged into the electrical appliance for charging, and the other end of the charging wire is electrically connected to the charging seat 100. Similarly, when the charging connection component 800 is a wireless charging module, the wireless charging module in the charging connection component 800 is electrically connected to the PCB 700, which is mainly connected through contacts. The wireless charging module is conventional and is placed in the charging connection component 800. The so-called charging connection component 800 plays the function of directly connecting with the electrical appliance, which can be a wired connection or a wireless connection.

[0042] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] Of course, the present invention is not limited to the above-mentioned embodiments, and those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
