[0002] With the rapid development of automobile technology, new energy vehicles have emerged as a new energy vehicle. New energy vehicles use unconventional automotive fuels as a power source, and more and more automakers are using high voltage and high current methods for high-power charging. In order to improve the charging time of new energy vehicles, dedicated charging connectors are required.

[0003] The existing automobile charging connector is a charging pile, and the charging pile is generally divided into a pile body, a cable and a charging gun. The charging gun is inserted into the car charging port, and then the pile body adjusts the charging parameters, and the cable ensures the transmission of current to complete the charging operation of the new energy vehicle. Therefore, when using the charging connector, the new energy vehicle is generally parked in a parking space for charging. However, when the driver encounters an emergency, he forgets to unplug the charging gun, resulting in the new energy vehicle being driven away directly, causing the charging gun inserted in the charging port to pull the pile body through the cable, causing damage to the components on the charging pile, resulting in large economic losses.

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] like Figures 1 to 9 As shown, a high-power charging connector for new energy vehicles is provided. The device includes a charging gun part 1, a connecting cable 2 is provided in the charging gun part 1, and the bottom of the connecting cable 2 extends to the outside of the charging gun part 1. The connecting cable 2 includes a connecting block 201, a connecting end 202 is movably sleeved on the inner side of the connecting block 201, a metal guide rod 203 is provided on the inner side of the connecting end 202, and a protective sleeve 204 is sleeved on the metal guide rod 203. There is a gap connection between the protective sleeve 204 and the connecting end 202. The inner cavities of the connecting end 202 and the protective sleeve 204 are provided with a connecting frame 205. The connecting frame 205 is elastically connected to the protective sleeve 204 and the connecting end 202 respectively through two springs 206;

[0033] The inner side of the connection block 201 is in contact with the lower end of the charging gun part 1;

[0034] When the connecting cable 2 is ejected from the inner cavity of the charging gun part 1, the elastic force of the two springs 1 206 drives the protective cover 204 and the connecting end 202 to move outward, removing the protective cover 204 from the inside of the metal guide rod 203. The protective cover 204 and the connecting frame 205 store the metal guide rod 203 in the inner cavity, preventing the metal guide rod 203 from being accidentally touched when the connecting cable 2 is ejected, thereby avoiding safety hazards.

[0035] The end of the metal guide rod 203 is electrically connected to a contact member located in the inner cavity of the connection end 202. A cable is installed inside the connection block 201. A conductive member is provided at the end of the cable. The contact member and the conductive member are in contact with each other.

[0036] When the charging gun 1 is pulled by the car, the cable pulls the connecting block 201, which drives the conductive parts inside to rotate together, so that the conductive parts and the contact parts remain connected, ensuring stable current transmission;

[0037] A mounting block 207 is provided on the inner side of the connecting block 201;

[0038] The connecting cable 2 is mounted on the charging gun 1 via the mounting block 207. When the driver forgets to unplug the charging gun 1 and starts driving, the connecting cable 2 drives the connecting block 201 to rotate, which in turn drives the mounting block 207 to rotate, thereby driving the mounting block 207 to slide out of the plug-in sleeve mechanism 3 and releasing the position limit on the mounting block 207, thereby facilitating the ejection of the connecting cable 2 from the charging gun 1.

[0039] The plug sleeve mechanism 3 is disposed outside the connecting cable 2 and inside the charging gun part 1. The plug sleeve mechanism 3 includes an outer sleeve assembly 310 and an inner sleeve assembly 320. The outer sleeve assembly 310 includes an outer shell 311, which is connected to the charging gun part 1. A plug end 312 is installed inside the outer shell 311, and the plug end 312 is socketed with the metal guide rod 203.

[0040] By inserting the metal guide rod 203 on the connecting cable 2 into the plug end 312, the current transmitted on the connecting cable 2 is directed to the charging gun part 1, thereby completing the charging of the car;

[0041] A limit ring 313 is provided at the end of the outer shell 311, and the outer shell 311 is elastically connected to the inner sleeve assembly 320 via a second spring 314;

[0042] When the connecting cable 2 is pulled and rotated, the cable drives the connecting block 201 to rotate, thereby driving the mounting block 207 to move in the inner cavity of the outer shell 311, so that the mounting block 207 squeezes the inner sleeve component 320 on the limiting ring 313, driving the inner sleeve component 320 to rotate, releasing the limit of the mounting block (207), and being used to eject the connecting cable 2 from the plug sleeve mechanism 3, so that the protective charging gun part 1 is automatically separated when it is pulled, thereby preventing the vehicle charging connector from being damaged;

[0043] A metal slide rail 315 is provided outside the plug end 312, and the metal slide rail 315 has a horizontal slide rail portion and an inclined slide rail portion;

[0044] The inner sleeve assembly 320 includes an inner housing 321 that is sleeved within the outer housing 311. Sliding blocks 322 are mounted on the outer side of the inner housing 321. The sliding blocks 322 are movably sleeved on the retaining ring 313 and are located on both sides of the mounting block 207. A slot 323 is defined within the inner housing 321, and one side of the slot 323 is provided with an inclined surface.

[0045] When the charging gun part 1 is forgotten to be unplugged from the car, the cable connected to the bottom of the charging gun part 1 is pulled due to the movement of the car, driving the connecting block 201 and the mounting block 207 to rotate, causing the sliding block 322 to rotate on the limiting ring 313. Then, the sliding block 322 drives the inner housing 321 to rotate, completing the squeezing and ejecting of the connecting cable 2. At the same time, when the mounting block 207 rotates, it slides out from the limit of the inner cavity of the outer housing 311, releasing the limit of the mounting block 207 on the outer housing 311.

[0046] The protective structure 4 is provided on the connecting cable 2 and includes a movable block 401 provided in the inner cavity of the protective sleeve 204. A guide rod 402 is provided on the outer side of the movable block 401. The other end of the guide rod 402 extends into the interior of the card slot 323.

[0047] When the driver forgets to unplug the car charging gun, after starting the vehicle, the car drives the charging gun part 1 and the connecting cable 2 to gradually rotate. The cable rotation drives the mounting block 207 to squeeze the sliding block 322, and then the inner housing 321 also rotates accordingly. During this process, the guide rod 402 on the movable block 401 continues to rotate within the slot 323 to keep the movable block 401 in the same position.

[0048] The movable block 401 is elastically connected to the protective sleeve 204 through a spring piece 403, and an inclined slot 404 is provided in the inner cavity of the movable block 401;

[0049] When the connecting cable 2 is separated from the plug-in sleeve mechanism 3, the protective sleeve 204 drives the guide rod 402 to move out of the slot 323. The elastic force of the spring 403 drives the movable block 401 to move upward, releasing the friction of the ball 405 on the metal guide rod 203, thereby facilitating the separation of the protective sleeve 204. The protective sleeve 204 protects the metal guide rod 203 extending outside, preventing accidental contact.

[0050] A ball 405 is provided in the inner cavity of the inclined groove 404. The outer surface of the ball 405 is in contact with the outer surface of the metal guide rod 203. The surface of the ball 405 is provided with rubber. A second spring piece 406 is installed on the inner wall of the inclined groove 404. The bottom of the second spring piece 406 is in contact with the ball 405.

[0051] The elastic force of the second spring piece 406 can continuously pressurize the ball 405 to prevent it from positional displacement. At the same time, when the connecting cable 2 is separated from the plug-in sleeve mechanism 3, the guide rod 402 moves out from the inside of the card slot 323, and the movable block 401 is driven to move upward by the action of the first spring piece 403, thereby releasing the squeezing of the ball 405 on the metal guide rod 203, and the protective sleeve 204 is driven to move out from the outside of the metal guide rod 203 by the first spring 206, protecting the end of the separated connecting cable 2 to prevent accidental touch. At the same time, when the movable block 401 moves upward, the second spring piece 406 is reset, thereby driving the ball 405 to move to the bottom of the inclined groove 404, and is limited by the reset of the second spring piece 406, so that the ball 405 is limited in the hole of the protective sleeve 204, blocking the hole on the protective sleeve 204, and avoiding safety hazards.

[0052] The ejection mechanism 5 is provided on the inner sleeve assembly 320 and includes a positioning rod 501 provided on the inner housing 321. A sleeve rod 502 is sleeved on the outer surface of the positioning rod 501. The other end of the sleeve rod 502 is connected to a push plate 503. The outer side of the push plate 503 contacts and connects with the inner side of the protective sleeve 204. A movable frame 504 is movably sleeved on the sleeve rod 502. A metal slider 505 located on the horizontal portion of the metal slide rail 315 is installed on the inner side of the movable frame 504.

[0053] When a pulling force is formed between the stretched cable and the charging gun part 1, the cable first drives the connecting block 201 and the mounting block 207 to rotate, and the mounting block 207 drives the inner shell 321 to move through the sliding block 322. As the inner shell 321 rotates, the sleeve rod 502 and the movable frame 504 on the positioning rod 501 are driven to rotate, and the metal slider 505 is driven to move on the horizontal part of the metal slide rail 315 through the movable frame 504. However, when the cable is pulled more, the connecting block 201 drives the inner shell 321 to rotate more, and the metal slider 505 moves from the horizontal part of the metal slide rail 315 to the inclined part. Then, the inclined part limits the metal slider 505, driving the movable frame 504 to move on the sleeve rod 502, and then the movable frame 504 drives the metal slider 505 to move from the inclined part of the metal slide rail 315 to the horizontal part, changing the position of the movable frame 504 on the sleeve rod 502;

[0054] The movable frame 504 is elastically connected to the push plate 503 via a spring 3 506;

[0055] As the inner housing 321 deflects, the metal slider 505 on the movable frame 504 moves along the horizontal and inclined parts of the metal slide rail 315, and the movable frame 504 moves forward along the sleeve rod 502. During the movement, the movable frame 504 continuously squeezes the spring 3 506. Then, as the connecting block 201 rotates continuously, the mounting block 207 releases the limit of the outer housing 311. At this time, the elastic force of the spring 3 506 squeezes the connection cable 2 to release the limit, and the connection cable 2 is ejected from the inside of the plug-in sleeve mechanism 3, thereby separating the charging gun part 1 and the cable. By separating the components, damage caused by pulling when the car charging gun is forgotten to be unplugged is prevented;

[0056] An alarm mechanism 6 is provided inside the plug socket mechanism 3. The alarm mechanism 6 includes a pressure block 601 disposed within the inner cavity of the plug end 312. The pressure block 601 is disposed below the metal slide rail 315. The bottom of the pressure block 601 is elastically connected to the plug end 312 via a spring clip 3 602. A buzzer 603 is provided within the inner cavity of the plug end 312.

[0057] When a driver forgets to unplug the charging gun while driving a new energy vehicle, a sufficiently long cable will be reserved between the vehicle charging gun and the charging pile. As the car drives out of the parking space, the cable will gradually become stretched between the charging gun and the cable, thereby generating a pulling force on the bottom of the charging gun. The cable will first drive the connecting block 201 to rotate, and the connecting block 201 will drive the inner shell 321 to rotate through the mounting block 207. At this time, the inner shell 321 drives the movable frame 504 to move in the horizontal metal slide rail 315. The metal slider 505 will squeeze the pressing block 601 during the rotation process. When the pressing block 601 moves downward, it will energize the disconnected buzzer 603, and then the buzzer 603 will sound an alarm to remind the driver that the charging gun is not unplugged, so as to avoid damage to the charging connector caused by excessive pulling.

[0058] The charging gun part 1 includes a gun body 101, a slide groove 102 is opened on the gun body 101, a grip 103 is installed inside the gun body 101, and a sliding gap 104 is set between the grip 103 and the gun body 101;

[0059] When the new energy vehicle needs to be charged, the driver holds the grip 103 of the gun body 101, closes the grip 103 and the gun body 101 to fill the sliding gap 104, and moves toward the inside of the gun body 101 along the sliding gap 104. At the same time, the bottom of the grip 103 is inserted into the slide groove 102, and the grip 103 is connected to the gun body 101. In this way, during the charging process of the charging gun part 1, the connecting cable 2 on the grip 103 will be moved forward for a distance as a whole, which will squeeze and drive the protective cover 204 to retreat. The ball 405 rests against the top of the inclined groove 404, so that when the protective sleeve 204 moves backward, it also drives the ball 405 to move backward, causing it to be pressed against the ball 405 by the spring 2 406 during the resetting process of the handle 103. Moreover, due to the large friction between the ball 405 and the metal guide rod 203, when the protective sleeve 204 is reset, the ball 405 frictionally contacts the metal guide rod 203, clamping the metal guide rod 203 in the protective sleeve 204, thereby stabilizing the connection between the metal guide rod 203 and the plug end 312.

[0060] The working principle and use process of the present invention:

[0061] When the charging gun 1 is forgotten to be unplugged, the car will first straighten the cable of sufficient length when driving out of the parking space. When a pulling force is generated between the stretched cable and the charging gun, the cable first drives the connecting block 201 to rotate. At this time, the rotating pressing block 601 gradually makes the disconnected circuit electrodes inside contact, thereby energizing the circuit. At this time, the internal buzzer 603 sounds an alarm. When the driver knows that the alarm comes from the charging gun, the driver's attention will be diverted to the rear of the car, so that the driver can see from the rearview mirror that the charging gun is not unplugged. When the charging gun of this design is commercially replaceable, the driver will hear the alarm and automatically brake.

[0062] When the driver continues to drive the vehicle in the above situation, the cable squeezes and rotates the bottom of the charging gun part 1, driving the cable and the connecting block 201 to rotate, and then driving the mounting block 207 to squeeze the sliding blocks 322 on both sides. The sliding blocks 322 rotate along the limiting ring 313, driving the sliding blocks 322 and the connected inner shell 321 to rotate. The metal slider 505 provided on the inner shell 321 moves within the metal slide rail 315 as it rotates. Guided by the horizontal part of the metal slide rail 315, the metal slider 505 and the movable frame 504 rotate horizontally, and the metal slider 505 squeezes the pressing block 601, driving the pressing block 601 to move downward, and the pressing block 601 triggers the buzzer 603, thereby reminding the driver that the charging gun part 1 has not been unplugged from the vehicle charging port.

[0063] However, when the driver pulls the charging gun out of the car's charging port, the elastic force of the second spring 314 drives the sliding block 322 to return to its original position. The sliding block 322 then drives the mounting block 207 and the connecting block 201 to rotate, thereby returning the charging gun part 1 to its original position, thereby facilitating the continued use of the car's charging connector.

[0064] At the same time, when the charging gun is not unplugged after the buzzer 603 sounds, the car continues to move, causing the cable to continuously pull the connecting block 201 to rotate, which drives the inner housing 321 to rotate through the mounting block 207, causing the metal slider 505 to gradually move from the horizontal portion on the metal slide rail 315 to the inclined portion. The metal slider 505 then drives the movable frame 504 to move on the sleeve rod 502, which is used to compress the spring 3 506. As the metal slider 505 moves forward, the elastic force of the spring 3 506 continues to increase.

[0065] At this time, after the metal slider 505 moves from the inclined part of the metal slide rail 315 to the horizontal part, the pressure on the spring three 506 is completed. Then, as the connecting block 201 continues to rotate, the mounting block 207 is released from the limit at the end of the outer shell 311. At this time, the elastic force exerted by the spring three 506 squeezes the connecting cable 2, separating the connecting cable 2 as a whole from the plug sleeve mechanism 3, and at the same time drives the metal guide rod 203 to be pulled out from the plug end 312, so as to disconnect the connection between the charging gun and the cable. In this way, if the driver forgets to unplug the new energy vehicle when using it, the charging gun part 1 can be separated from the cable to avoid damage to the cable or the charging gun part 1 caused by the pull of the car when starting, thereby preventing the subsequent continued use from being affected.

[0066] When the plug end 312 does not pop out from the inner shell 321, the slot 323 opened on the inner shell 321 limits the guide rod 402, so that the movable block 401 will not be offset when the inner shell 321 rotates. Then, when the plug end 312 pops out from the inner shell 321, the guide rod 402 moves out from the inside of the slot 323, releasing the limit on the guide rod 402, and the elastic force of the spring piece 403 drives the movable block 401 to move outward, driving the movable block 401 and the ball 405 to move upward, and then the upper part of the movable block 401 moves, releasing the ball 405 frictionally blocks the metal guide rod 203, and at the same time, the pop-up plug end 312 drives the protective sleeve 204 outward through the spring 1 206, and the metal guide rod 203 is received in the protective sleeve 204 cavity. At this time, the ball 405 releases the squeeze on the metal guide rod 203, so that the spring 2 406 pushes the ball 405 against the bottom of the inclined groove 404 and falls into the protective sleeve 204 cavity, and is used to block the protective sleeve 204 cavity, so that the separated metal guide rod 203 is protected by the ball 405 to prevent accidental touch by people and avoid safety hazards;

[0067] Afterwards, when the charging gun part 1 needs to be reset and installed after being separated from the cable, the unfolded protective sleeve 204 is inserted into the inner shell 321, and then the spring 1 206 is squeezed, and the metal guide rod 203 on the plug end 312 moves along the inner cavity of the protective sleeve 204, and the metal guide rod 203 squeezes the blocked ball 405, and squeezes the ball 405 out of the installation port of the metal guide rod 203 on the protective sleeve 204, and falls into the inclined groove 404, and then the mounting block 207 on the connecting block 201 is fitted with the outside of the outer shell 311, and the bottom of the mounting block 207 is inserted between the sliding block 322, thereby rotating the connecting block 201, and the sliding block 322 is driven to rotate on the limiting ring 313 by the bottom of the mounting block 207, and the mounting block 207 is rotated to the end opening of the outer shell 311, thereby pressing the connecting block 201 and the mounting block 20 When the cam 201 is in the closed position, the spring 207 is pressed against the guide rail 203 and the spring 206 is pressed against the guide rail 203. ...
