[0036] Example 1:

[0037] An integrated European standard charging gun for new energy electric vehicles comprises: a housing 1;

[0038] A wiring tube 2, the wiring tube 2 being installed at a wiring terminal of the housing 1;

[0039] A control mainboard 3 , the surface of which is embedded in the inner surface of the housing 1 ;

[0040] The gun head assembly 4 is installed at the output end of the housing 1. The gun head assembly 4 includes a connecting tube 41 and a charging head 42. The charging head 42 is installed on the inner surface of the connecting tube 41. The charging head 42 is provided with a socket 421 and a buffer groove 422. The detection assembly 43 is installed inside the buffer groove 422.

[0041] The regulating switch 5 is fixedly mounted on the housing 1 .

[0042] By setting up a detection component 43 inside the charging head 42, it is possible to detect whether the docking of the charging interface is completed. After complete docking, the input end of the gun head component 4 can normally input power to charge the vehicle body charging interface. When there is an abnormality in the detection component 43 and the detection is not complete, there is no power output at the output end of the gun head component 4, and the gun head component 4 and the control motherboard 3 are in a disconnected state, which prevents non-users from unplugging and playing with the device during charging, especially children. This is especially important when using unattended outdoor charging piles to enhance the protection of the environment and children after the charging piles are deployed.

[0043] The interior of the buffer slot 422 is communicated with the interior of the jack 421 , and the output end of the detection component 43 is electrically connected to the power output end of the control mainboard 3 .

[0044] The detection component 43 includes a contact switch 431 and a buffer spring 432. The bottom end of the buffer spring 432 is fixedly installed on the bottom of the inner wall of the buffer groove 422. The top end of the buffer spring 432 is fixedly connected to the bottom of the contact switch 431. The surface of the contact switch 431 is located between the inside of the hole 421 and the inside of the buffer groove 422.

[0045] The upper surface of the contact switch 431 is an arc-shaped structure and is located between the buffer groove 422 and the inside of the insertion hole 421. When the contact switch 431 is pressed, it can stably shrink into the inside of the buffer groove 422.

[0046] There are at least five groups of contact switches 431 , and the five groups of contact switches 431 are connected in series to the control end of the charging head 42 .

[0047] The installation structure and connection structure of each group of contact switches 431 are the same. Each group of contact switches 431 corresponds to a buffer slot 422, and at least five jacks are provided.

[0048] The wiring tube 2 is made of rubber, and the surface of the wiring tube 2 adopts a mesh structure.

[0049] Provide buffering for line connection to ensure stability after line connection.

[0050] The input end of the control main board 3 is welded to the output end of the wiring tube 2 , and the control end of the control main board 3 is adapted to the regulating switch 5 .

[0051] The housing 1 is formed by an integral glue-injection process, and a handle is reserved on the housing 1 .

[0052] The working principle of the integrated European standard charging gun for new energy electric vehicles provided by the present invention is as follows:

[0053] When the socket 421 of the charging head 42 is fully connected to the plug of the vehicle body charging interface, the detection component 43 is fully activated, and the output end of the control motherboard 3 can normally provide power to the input end of the charging head 42, thereby providing charging support for the new energy vehicle;

[0054] When the charging head 42 is unplugged, the detection component 43 is in a completely closed state, and the output end of the control mainboard 3 cannot provide power to the input end of the charging head 42;

[0055] When a child inserts a finger or other object into the charging head 42, the separate detection component 43 is activated, and the control motherboard 3 cannot normally supply power to the charging head 42, while providing stable support and protection for the safety of children or non-professionals, so that the charging pile can be installed and used in an unsupervised outdoor environment.

[0056] Compared with related technologies, the integrated European standard charging gun for new energy electric vehicles provided by the present invention has the following beneficial effects:

[0057] By setting up a detection component 43 inside the charging head 42, it is possible to detect whether the docking of the charging interface is completed. After complete docking, the input end of the gun head component 4 can normally input power to charge the vehicle body charging interface. When there is an abnormality in the detection component 43 and the detection is not complete, there is no power output at the output end of the gun head component 4, and the gun head component 4 and the control motherboard 3 are in a disconnected state, which prevents non-users from unplugging and playing with the device during charging, especially children. This is especially important when using unattended outdoor charging piles to enhance the protection of the environment and children after the charging piles are deployed.

[0058] Example 2:

[0059] The surface of the charging head 42 is slidably connected to the inner surface of the connecting tube 41 , and a mounting groove 423 is provided on the charging head 42 . A fixing plate 6 is fixedly installed on the inner wall of the connecting tube 41 , and a telescopic member 61 is fixedly installed on the inner wall of the mounting groove 423 .

[0060] The interface portion of the charging head 42 is movably connected to the connecting tube 41. The telescopic member 61 adopts an electric telescopic rod when in use. When in use, the power is connected through the control motherboard 3. The telescopic member 61 provides sliding support for the telescopic adjustment of the charging head 42 when in use;

[0061] When the telescopic part 61 contracts, it is convenient to drive the charging head 42 to contract inside the connecting tube 41. When the charging head 42 contracts, the charging head 42 and the charging interface can be disconnected from the power supply without the gun head assembly 4 part being separated from the charging interface of the vehicle body, so as to facilitate the separation of the charging head 42 and the interface after full charging, and avoid long-term connection of the interface which may affect the service life of the charging head 42, especially when the user forgets to unplug the charging gun.

[0062] The surface of the telescopic member 61 is adapted to the inner surface of the mounting groove 423 , and the output end of the telescopic member 61 is fixedly connected to the surface of the fixing plate 6 .

[0063] The front end surface of the charging head 42 and the front end surface of the connecting tube 41 are on the same plane, and the top end of the charging head 42 is a planar structure.

[0064] Beneficial effects:

[0065] The retractable and adjustable charging head 42 facilitates the automatic plugging and unplugging of the charging structure without unplugging the gun head assembly 4 from the vehicle charging port. Although the gun head is still installed on the vehicle charging port, the internal charging head 42 has been separated. After charging is completed, even if the gun head assembly 4 is not unplugged, the impact of long-term plugging on the charging head 42 is reduced.

[0066] Based on Example 2, under the condition that the charging head 42 can be retracted and adjusted, the following supplement is made. This embodiment is not connected to the charging port when retracted, is used in a non-charging environment, and operates independently in conjunction with Example 2, and does not conflict with Example 2:

[0067] Furthermore, a contraction groove 411 and a connecting hole 412 are respectively provided on the connecting tube 41, the interior of the connecting hole 412 is communicated with the interior of the contraction groove 411, and the interior of the connecting hole 412 is communicated with the interior of the connecting tube 41, and the inner wall of the contraction groove 411 is installed with a supporting shaft 7, the surface of the supporting shaft 7 is rotatably connected to the rotating rod 71, one side of the rotating rod 71 is fixedly connected to a protective cover 72, one side of the protective cover 72 is fixedly connected to a telescopic ring 73, one side of the telescopic ring 73 is fixedly connected to a contraction spring 74, one side of the contraction spring 74 is fixedly connected to the inner wall of the contraction groove 411, one side of the rotating rod 71 is fixedly connected to a traction rope 8, the surface of the traction rope 8 passes through the interior of the connecting hole 412 and extends to the interior of the connecting tube 41, and the bottom end of the traction rope 8 is fixedly connected to the top of the charging head 42.

[0068] When the battery is fully charged, the charging head 42 is automatically charged and the charging port 42 is automatically charged, so that the charging head 42 can be charged and the battery is fully charged.

[0069] When the charging head 42 needs to be used, the charging head 42 is preferably extended outward and reset to keep the charging head 42 in use. When the charging head 42 extends and moves, the telescopic ring 73 contracts and moves under the elastic tension of the contraction spring 74. When the telescopic ring 73 contracts and moves, it can synchronously drive the protective cover 72 to move toward the inside of the contraction groove 411. When the protective cover 72 moves, it is convenient to drive the rotating rod 71 to rotate downward through the traction rope 8. When the rotating rod 71 rotates downward, the protective cover 72 gradually contracts inside the contraction groove 411, thereby facilitating the stable rotation and contraction of the rotating rod 71, thereby facilitating the opening and use of the charging head 42 and providing support for the normal use of the equipment.

[0070] Beneficial effects:

[0071] The rotating rod 71 can drive the protective cover 72 to fully unfold and block and protect the charging port of the charging head 42, so that the gun head assembly 4 can be automatically blocked and protected when not in use, preventing non-charging personnel from damaging and clogging the charging gun head. At the same time, it can prevent the entry of dirt and dust into the interior of the gun head, thereby improving the protection of the charging gun head during installation and use, and extending the service life of the charging gun head. The above is only an embodiment of the present invention and does not limit the scope of the patent of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly used in other related technical fields, are also included in the scope of patent protection of the present invention.
