[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.
[0019] See also Figures 1 to 6The present invention provides a charging head for new energy vehicles that is easy to connect, including a charging head body 1 and a connecting head 2 connected to the end of the charging head body 1, the connecting head 2 is connected to a buffer mechanism, and there are two buffer mechanisms, which are relatively distributed. The buffer mechanism includes a connecting plate 3, an arc plate 12, a connecting block 21, and two springs 22. One end of the connecting plate 3 is rotatably connected to the connecting head 2, and the other end is fixed to the charging head body 1. The connecting block 21 is fixedly connected to the connecting plate 3, and the connecting block 21 is movably connected to the arc plate 12. The two ends of the spring 22 are connected to the connecting block 21 and the arc plate 12. When the charging head body 1 is impacted, the impact direction is Figure 5 In the middle X direction, b represents the spring 22 on one side, and c represents the spring 22 on the other side. c is stretched and b is compressed. The two springs 22 are used together to achieve a good buffering effect. When the impact force disappears, the spring 22 drives the connecting block 21 to return to its original position, and simultaneously drives the connecting plate 3 and the charging head body 1 to return to their original position, which is convenient for the subsequent limiting protrusion 14 to dock with the connecting plate 3. The connecting head 2 is connected to a docking mechanism for docking with the car charging port 6, and the docking mechanism is used to limit the connecting plate 3.
[0020] When charging, hold the charging head body 1 and align the connector 2 with the car charging port 6. At this time, the limiting protrusion 14 and the connecting plate 3 are in a docking state, realizing the limiting of the connecting plate 3. At this time, the charging head body 1 and the connector 2 are equivalent to an integrated design, which is convenient for controlling the position of the connector 2. Then insert the connector 2 into the quasi-car charging port 6, and push the moving plate 9 forward to connect the positioning block 10 with the limiting seat 5. At this time, the spring 3 26 is in a compressed state, which can press the connector 2 against the car charging port 6, that is, the sealing surface 11 is pressed against the connecting surface 16, which can improve the stability and tightness of the connection between the two, facilitate charging operations, and prevent external dust and water stains from invading the interior of the car charging port 6 to cause leakage. It is safe and reliable to use.
[0021] The buffer mechanism also includes an arc guide column 23 and an arc groove 24. The arc groove 24 is provided on the arc plate 12. The connecting block 21 is slidably connected to the arc groove 24. The arc guide column 23 runs through the connecting block 21. After the connector 2 is docked with the car charging port 6, the limiting protrusion 14 and the connecting plate 3 are in a separated state, so that the connecting plate 3 is loosened. When the charging head body 1 is hit, the charging head body 1 rotates around the axis of the fixed shaft 4, and synchronously drives the connecting plate 3 to rotate, so that the connecting block 21 slides in the arc groove 24. The spring 22 can absorb the corresponding impact force, which has a good buffering effect. Secondly, it effectively prevents the connector 2 from causing damage to the car charging port 6, which is convenient for continuing the charging operation and has strong practicality.
[0022] The arc-shaped guide pillar 23 is fixed in the arc-shaped groove 24 , and the second spring 22 is sleeved on the arc-shaped guide pillar 23 . The arc-shaped guide pillar 23 and the arc-shaped groove 24 play a good guiding role for the connecting block 21 .
[0023] The outer side of the connecting head 2 is connected with a fixed shaft 4, and the end of the connecting plate 3 is rotatably connected to the fixed shaft 4. When the charging head body 1 is hit, the charging head body 1 and the connecting plate 3 can rotate around the axis of the fixed shaft 4.
[0024] The docking mechanism includes a limiting protrusion 14, a movable plate 9, a pressing block 8, a positioning block 10, a lifting plate 18, an inclined surface 19, two springs 1 20, a guide block 25, a spring 3 26, a slide groove 27, and a straight guide column 28. The limiting protrusion 14 is connected to the end of the movable plate 9, and the limiting protrusion 14 is used to position the connecting plate 3, the slide groove 27 is used to guide the guide block 25, the straight guide column 28 runs through the guide block 25, the spring 3 26 is used to drive the guide block 25 to move toward the direction close to the charging head body 1, the guide block 25 is connected to the bottom of the movable plate 9, the pressing block 8 and the movable plate 9 can be lifted and connected to the movable plate 9, the two ends of the lifting plate 18 are connected to the pressing block 8 and the movable plate 9, the two ends of the spring 1 20 are connected to the lifting plate 18 and the movable plate 9, and the inclined surface 19 is set on the positioning block 10. When the connector 2 is connected to the car charging port 6, the pressing block 8 can be manually pushed forward, and the movable plate 9 can be driven forward synchronously. At this time, the guide block 25 slides in the slide groove 27, and the spring three 26 is gradually compressed. The inclined surface 19 slides relative to the front end of the limit seat 5, and the positioning block 10 can be driven to move downward. The spring one 20 is gradually compressed until the positioning block 10 completely penetrates the limit seat 5. The compressed spring one 20 drives the positioning block 10 to return, so that the positioning block 10 is connected to the rear end of the limit seat 5. At this time, the spring three 26 is in a compressed state. According to the reaction of the force, the connection between the connector 2 and the car charging port 6 is stable. When the connector 2 needs to be separated from the car charging port 6, pressure is applied to the pressing block 8, and the use of the lifting plate 18 can simultaneously drive the positioning block 10 to move downward until the positioning block 10 is aligned with the connecting hole 15, that is, the top of the positioning block 10 is aligned with the e-plane of the top of the connecting hole 15, so that the positioning block 10 is loosened, and the compressed spring three 26 drives the moving plate 9 to return quickly, and the positioning block 10 is away from the limit seat 5, so that the connector 2 is loosened, which is convenient for separation from the car charging port 6, and the operation is simple and convenient.
[0025] The end of the connecting plate 3 is provided with a connecting groove 13, and the limiting protrusion 14 matches the connecting groove 13. When the charging head is not in use, the spring three 26 applies a thrust to the guide block 25, so that the limiting protrusion 14 is always connected to the connecting groove 13 to limit the connecting plate 3. At this time, the charging head body 1 and the connecting head 2 are equivalent to an integrated design. Holding the charging head body 1 facilitates the operation of the connecting head 2 and facilitates docking with the car charging port 6. During the charging process, the limiting protrusion 14 and the connecting groove 13 are in a separated state. At this time, the charging head body 1 has good impact resistance. When charging is completed, the compressed spring three 26 drives the moving plate 9 to return to its position, so that the limiting protrusion 14 is automatically connected to the connecting groove 13. At this time, the charging head body 1 and the connecting head 2 are an integrated structure.
[0026] The spring three 26 is sleeved on the straight guide column 28 , and the two ends of the spring three 26 are connected to the guide block 25 and the connector 2 .
[0027] The positioning block 10 matches the limiting seat 5 arranged outside the car charging port 6. A connecting hole 15 is arranged in the limiting seat 5. The size of the connecting hole 15 is larger than the positioning block 10. In the initial position, the top plane of the positioning block 10 is higher than the e-plane.

At this time, the spring 3 26 is in a compressed state, so that the positioning block 10 applies a pulling force to the limiting seat 5, thereby improving the stability of the connection between the connector 2 and the car charging port 6 and preventing the connector 2 from being accidentally loosened. At the same time, the sealing surface 11 is pressed against the connecting surface 16 to improve the sealing performance of the connection between the connector 2 and the car charging port 6. At this time, the limiting protrusion 14 is separated from the connecting plate 3 to loosen the connecting plate 3. Step 3: When the charging head body 1 is hit, the charging head body 1 will rotate, synchronously driving the connecting plate 3 to rotate, and the spring 22 can absorb the corresponding impact force, play a good buffering effect, and secondly effectively prevent the connecting head 2 from causing damage to the vehicle charging port 6.
