DETAILED DESCRIPTION

[0026] The embodiments of the present application disclose a household power adapter. Through the arrangement of the pushing spring 302 and the pushing plate 303, when the vertical connection platform 3 is unlocked, the elastic force of the pushing spring 302 can cause the pushing plate 303 to push out the pin 2, so that a part of the pin 2 can be exposed, facilitating the user to pinch the pin 2 with the hand and then pull out the pin 2, achieving the effect of automatically pushing out the pin 2. When not in use, the pin 2 can enter the power adapter housing 1 for storage, preventing it from rubbing and colliding with other items in the bag, thereby improving the safety of the power adapter during use.

[0027] To better understand the above technical solution, the following will describe the above technical solution in detail in conjunction with the specification drawings and specific embodiments.

[0028] Embodiment 1: Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 5 A household power adapter disclosed in the embodiments of the present application includes a pin 2. The pin 2 is arranged inside the power adapter housing 1. A guide plate 205 is fixedly arranged on one side of the pin 2. Side guide posts 206 are symmetrically and fixedly arranged on the outside of the guide plate 205. Second magnets are arranged at one ends of the side guide posts 206. A vertical connection platform 3 is arranged inside the power adapter housing 1. A guide port 3011 is opened on one side of the vertical connection platform 3. An anti-friction inner layer 3012 is fixedly arranged on the inner side of the guide port 3011. The guide plate 205 is slidably arranged inside the anti-friction inner layer 3012. Fixed plates 301 are symmetrically and fixedly arranged on both sides of the vertical connection platform 3. The fixed plates 301 are fixedly connected to a pushing plate 303 through a pushing spring 302. A first magnet 3041 is arranged on the other side of the pushing plate 303. The pushing plate 303 is slidably arranged on both sides of the vertical connection platform 3. The first magnet 3041 and the second magnet are arranged with opposite polarities.

[0029] When pushing out the pin 2, the pin 2 can be pushed out partially by the elastic force of the pushing spring 302, facilitating the pulling out of the pin 2.

[0030] When retracting the pin 2, the pin 2 is pushed forcefully into the inside of the power adapter housing 1, so that the second magnet attracts the first magnet 3041, preventing the pin 2 from being easily detached, further improving the degree of stable storage of the pin 2 inside. At the same time, the pushing plate 303 will be pushed, causing the pushing spring 302 to be in a compressed state until the locking block 307 is located on the other side of the fixed plate 301. At this time, the pin 2 is completely inside the power adapter housing 1. When unlocking, with the downward pressing of the pressing frame 401, the connecting plate 311 can drive the guide pressure rod 309 and the unlocking block 308 to press down together, and then the locking block 307 leaves the fixed plate 301, thus reaching the unlocking state, which is simple and convenient to use.

[0031] Among them, the friction-increasing inner layer 3012 is made of rubber material. On one side of the pin 2, a first connecting arm 201 is symmetrically and rotatably arranged. At the other end of the first connecting arm 201, a connecting member 202 and a second connecting arm 203 are rotatably arranged. At the other end of the second connecting arm 203, a transfer rod 204 is fixedly arranged. On one side of the connecting member 202, a sealing plate 207 is fixedly arranged. The transfer rod 204 is rotatably arranged at the inner top end of the power adapter housing 1. At the bottom end of the vertical connection platform 3, a power main board 106 is fixedly arranged. The power main board 106 is fixedly arranged at the inner bottom end of the power adapter housing 1. Heat dissipation openings 101 are formed on both sides of the power adapter housing 1.

[0032] The material of the friction-increasing inner layer 3012 is set as the friction-increasing inner layer 3012 to increase the resistance of the pin 2 to slide, so as to facilitate the insertion of the pin 2 into the socket jack and prevent the pin 2 from moving easily. When the pin 2 moves, the angle between the first connecting arm 201 and the second connecting arm 203 will become larger, so that the sealing plate 207 moves away from the heat dissipation opening 101, facilitating the heat dissipation of the internal power main board 106. When the sealing plate 207 seals the heat dissipation opening 101, it can prevent external dust from entering the power adapter housing 1.

[0033] Further, referring to Figure 3 and Figure 5 , on the other side of the pushing plate 303, a bracket 304 is fixedly arranged. A sliding guide post 306 is penetrated and slidably arranged on one side of the bracket 304. A reset spring 305 is fixedly arranged on the side of the bracket 304 close to the vertical connection platform 3. The other ends of the reset spring 305 and the sliding guide post 306 are fixedly arranged with a locking block 307. The side of the locking block 307 close to the fixing plate 301 is beveled. On the other side of the fixing plate 301, an unlocking block 308 is slidably arranged. The side of the unlocking block 308 away from the vertical connection platform 3 is beveled. The unlocking block 308 is fixedly connected to the receiving connecting plate 311 through a guide pressure rod 309. A suspension cylinder 310 is slidably arranged on the outer side of the guide pressure rod 309. The suspension cylinder 310 is fixedly arranged at the inner top end of the power adapter housing 1.

[0034] While the sealing plate 504 is being opened, the pin 2 will slowly emerge from the inside of the power adapter housing 1. The moving force of the pin 2 comes from the elastic force of the pushing spring 302. The elastic force of the pushing spring 302 will push the pushing plate 303, thereby pushing the side guide post 206 and the guide plate 205, enabling the pin 2 to move. Then the user can pinch the pin 2 and pull it out forcefully. And due to the setting of the friction-increasing inner layer 3012, the pin 2 will not move easily when inserted into the socket jack.

[0035] Embodiment 2: Referring to Figure 2 , Figure 4 , Figure 6 , Figure 7 and Figure 8A driving assembly 4 is symmetrically arranged on one side of the front baffle 104, and the driving assembly 4 includes a pressure frame 401, and a connecting rod 402 is symmetrically fixedly arranged on one side of the bottom end of the pressure frame 401, and a fixed sliding shell 405 is slidably arranged on the outer side of the connecting rod 402, and a return spring 403 is fixedly arranged on the inner bottom end of the fixed sliding shell 405, and a tooth block 404 is fixedly arranged on the other end of the connecting rod 402 and the return spring 403, and the top side of the tooth block 404 is an inclined surface setting, and the pressure frame 401 is fixedly connected to the connecting plate 311, and an elastic telescopic rod 4011 is fixedly arranged on one side of the top end of the pressure frame 401, and a slider 4012 is fixedly arranged on the other end of the elastic telescopic rod 4011, and the height of the tooth block 404 is less than the unlocking block 308.

[0036] When the slider 4012 is slid into the second groove 103, the elastic telescopic rod 4011 will be compressed, so that the slider 4012 can enter the first groove 102 and return to its original position after use, and the pressing frame 401 is pressed down, so that the connecting rod 402 can drive the tooth block 404 to slide on the inner side of the fixed sliding shell 405, and the return spring 403 will be compressed. The compression of the return spring 403 will generate a rebound force, so that the tooth block 404, the connecting rod 402 and the pressing frame 401 can automatically rise. When the spur plate 407 moves into place, the pressing frame 401 can be released.

[0037] Specifically, the driving assembly 4 also includes a beveled tooth plate 406 and a spur tooth plate 407. The beveled tooth plate 406 is fixedly arranged at the bottom end of the spur tooth plate 407, and the beveled tooth plate 406 is engaged with the tooth block 404. A force storage spring 409 is fixedly arranged on one side of the spur tooth plate 407, and a fixed plate 410 is fixedly arranged on the other end of the force storage spring 409. The fixed plate 410 is fixedly arranged on one side of the interior of the power adapter housing 1. A fixed slide 408 is slidably arranged on one side of the spur tooth plate 407, and the fixed slide shell 405 is fixedly arranged on one side of the fixed slide 408. The fixed slide 408 is fixedly arranged on one side of the front baffle 104. The pressure frame 401 passes through and is slidably arranged on the top end of the power adapter housing 1. The top end of the power adapter housing 1 is provided with a first groove 102 and a second groove 103. The pressure frame 401 is located on the inner side of the second groove 103, and the slider 4012 is slidably arranged on the inner side of the first groove 102.

[0038] When using the driving assembly 4, first slide the slider 4012 into the second groove 103, so that the pressure frame 401 can move up and down freely, and the pressure frame 401 can be directly pressed down to make the locking tooth block 404 leave the bevel tooth plate 406. At the same time, the bevel tooth plate 406 and the straight tooth plate 407 will automatically move by relying on the elastic force of the force storage spring 409, thereby providing the opening and closing mechanism 5 with the required power for opening, and the setting of the fixed slide 408 allows the straight tooth plate 407 to move along a straight line.

[0039] Example 3: Reference Figure 2, Figure 6 and Figure 7 , on the inner side of the inlet and outlet 105, an opening and closing mechanism 5 is symmetrically arranged. The opening and closing mechanism 5 includes a connecting drive gear 501. One end of the connecting drive gear 501 is fixedly provided with a connecting arm rod 502. On the outer side of the connecting arm rod 502, first rotating arms 503 are symmetrically and fixedly arranged. The other end of the first rotating arm 503 is rotatably provided with a sealing plate 504. The connecting drive gear 501 is meshed and connected with a straight tooth plate 407. On one side of the sealing plate 504, second rotating arms 509 are symmetrically rotatably arranged. The connecting drive gear 501, the connecting arm rod 502 and the second rotating arms 509 are all rotatably arranged at the top and bottom of the inner side of the front baffle 104. The first rotating arm 503 is arranged in the middle of one side of the sealing plate 504.

[0040] When the straight tooth plate 407 is pushed to move, the connecting drive gear 501 in the opening and closing mechanism 5 rotates, thereby driving the connecting arm rod 502 to rotate, so that the first rotating arm 503 can drive the sealing plate 504 to move, achieving the effect of opening the sealing plate 504. The state of the second rotating arm 509 will change accordingly, so that the sealing plate 504 can move along a specific trajectory.

[0041] Among them, referring to Figure 7 , on one side of the sealing plate 504, a first cushion plate 505 is fixedly provided. On the other side of the first cushion plate 505, an elastic member 506 is rotatably provided. On the other side of the elastic member 506, a second cushion plate 507 is rotatably provided. A support arm 508 is arranged between the first cushion plate 505 and the second cushion plate 507. The elastic member 506 is made of a shape memory alloy material.

[0042] Gently press the power adapter housing 1, so that the elastic member 506 deforms, and the first cushion plate 505 and the second cushion plate 507 will approach, and the connecting drive gear 501 will rotate, and the straight tooth plate 407 will move. Then, the slider 4012 is put into the first groove 102 to achieve a locking effect. Thus, the power adapter housing 1 can be completely inserted into the socket jack, and further, the power adapter can achieve the effect of converting alternating current into direct current.

[0043] Working principle: When in use, first move the slider 4012 in the driving component 4 to one side, so that the elastic telescopic rod 4011 is compressed. After the slider 4012 enters the second groove 103, the pressing frame 401 can move freely up and down. At the same time, the elastic force of the energy storage spring 409 makes the helical tooth plate 406 and the straight tooth plate 407 move to one side. The movement of the helical tooth plate 406 enables the tooth locking block 404 to move up and down. Due to the shape design of the tooth teeth of the helical tooth plate 406 and the tooth locking block 404, the helical tooth plate 406 cannot move back actively. When the tooth locking block 404 descends, the return spring 403 will be compressed. The elastic force of the return spring 403 makes the tooth locking block 404 rise, so that the tooth locking block 404 will be stuck into the next tooth. The movement of the straight tooth plate 407 makes the drive gear 501 in the opening and closing mechanism 5 rotate, and then drives the connecting arm rod 502 to rotate, so that the first rotating arm 503 can drive the sealing plate 504 to move, achieving the effect of opening the sealing plate 504, and the state of the second rotating arm 509 will change accordingly, so that the sealing plate 504 can move along a specific trajectory; At this time, the energy storage spring 409 is at its original length. It should be noted that when the sealing plate 504 is in the closed state, the energy storage spring 409 is in a compressed state. Since the initial position of the slider 4012 is in the first groove 102, the pressing frame 401 cannot move up and down, thus achieving a locking effect on the closing sealing plate 504; When the sealing plate 504 is being opened, the plug 2 will slowly protrude from the inside of the power adapter housing 1. The moving force of the plug 2 comes from the elastic force of the pushing spring 302. The elastic force of the pushing spring 302 will push the pushing plate 303, thereby pushing the side guide post 206 and the guide plate 205, enabling the plug 2 to move. Then the user can pinch the plug 2 and pull it out forcefully. And due to the setting of the friction increasing inner layer 3012, the plug 2 will not move easily when inserted into the socket jack. While the plug 2 is moving, the angle between the first connecting arm 201 and the second connecting arm 203 will become larger, so that the blocking plate 207 leaves the heat dissipation port 101, facilitating the heat dissipation of the internal power main board 106. When the blocking plate 207 blocks the heat dissipation port 101, it can prevent external dust from entering the power adapter housing 1; When the plug 2 is inserted into the socket jack, the sealing plate 504 will contact the socket. At this time, gently press the power adapter housing 1, so that the elastic member 506 is deformed, and the first cushion plate 505 and the second cushion plate 507 will approach, and the drive gear 501 will rotate, and the straight tooth plate 407 will move. Then the slider 4012 is put back into the first groove 102 to achieve a locking effect. At this time, the pressing frame 401 returns to its original state. When closing the sealing plate 504, the driving component 4 unlocks the elastic member 506. At this time, through the elastic force of the elastic member 506, the whole power adapter housing 1 can retreat backward by a certain distance, so that the power adapter can be removed without having to pull out the plug 2 forcefully; When retracting the pin 2, the pin 2 can be pushed forcefully into the interior of the power adapter housing 1, causing the second magnet to attract the first magnet 3041, preventing the pin 2 from easily detaching, further improving the degree of stable internal storage of the pin 2. At the same time, the push plate 303 will be pushed, causing the push spring 302 to be in a compressed state until the locking block 307 is located on the other side of the fixed plate 301. At this time, the pin 2 is completely inside the power adapter housing 1. When unlocking, as the pressure frame 401 is pressed down, the connecting plate 311 can drive the guide pressure rod 309 and the unlocking block 308 to be pressed down together, and then the locking block 307 leaves the fixed plate 301, thus achieving the unlocking state, which is simple and convenient to use; After the pin 2 is retracted, manually move the sealing plate 504 so that the sealing plate 504 enters the inlet 105. This step is carried out when the second magnet attracts the first magnet 3041. While continuing to push the pin 2, manually close the sealing plate 504, thereby achieving the effect of blocking the inlet 105 and preventing foreign objects from entering the power adapter housing 1, protecting the electronic components inside the power adapter housing 1; It should be noted that the height of the tooth block 404 is different from that of the unlocking block 308, and the height of the unlocking block 308 is greater than that of the tooth block 404. When closing the sealing plate 504, only need to gently press the pressure frame 401 to prevent the unlocking block 308 from contacting the locking block 307. Therefore, when the pin 2 completely enters the power adapter housing 1 and the locking block 307 is locked, the unlocking block 308 will not unlock the locking block 307, which can not only make the pin 2 be retracted smoothly but also make the sealing plate 504 be closed smoothly, and is simple and convenient to use.

[0044] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these modifications and variations.
