Description

Technical Field

[0001] This invention relates to the field of new energy vehicles, and in particular to an integrated European standard charging gun for new energy electric vehicles. Background Technology

[0002] New energy vehicles refer to automobiles that use unconventional vehicle fuels as a power source and integrate advanced technologies in vehicle power control and drive, resulting in vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include four main types: hybrid electric vehicles, pure electric vehicles, fuel cell electric vehicles, and other new energy vehicles. Unconventional vehicle fuels refer to fuels other than gasoline and diesel.

[0003] For new energy vehicles, they are all equipped with a charging gun for charging. The charging gun consists of two parts: a charging head and a connecting wire. The charging head is connected to the output wire of the charging pile through the connecting wire. When in use, the charging head is plugged into the charging port of the new energy vehicle to complete the charging.

[0004] In related technologies, to ensure the safety of charging guns during use, some charging guns have a protective cover on the outside of the charging head to protect the front connector. When charging, people need to manually remove the protective cover, press the start switch, and then connect it to the car interface. The whole process requires three steps, which is relatively slow and troublesome to use.

[0038] First Embodiment

[0039] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 A schematic diagram of the external structure of the integrated European standard charging gun for new energy electric vehicles provided by the present invention; Figure 2 A schematic diagram of the internal structure of the integrated European standard charging gun for new energy electric vehicles provided by the present invention. Figure 3 for Figure 2 The enlarged schematic diagram of part A shown below; Figure 4 for Figure 2 The diagram shows the external structure of the control circuit board and rotating clamp. The integrated European standard charging gun for new energy electric vehicles includes:

[0040] Casing 1;

[0041] The plug structure 2 is disposed inside the housing 1. The plug structure 2 includes a plug 21, a rotating locking member 22, and a sliding rod 23. The plug 21 slides on the right side inside the housing 1. The rotating locking member 22 rotates on the upper side inside the housing 1. The sliding rod 23 is fixedly installed between the two sides of the inner wall of the housing 1. A sliding block 24 is slidably connected to the outside of the sliding rod 23. An elastic member 25 is sleeved on the outside of the sliding rod 23 and on the left side of the sliding block 24. A connecting groove 26 is opened on the top of the plug 21. A button 27 is fixedly installed on the left side of the rotating locking member 22. A support spring 28 is fixedly installed on the bottom of the button 27.

[0042] The control structure 3 is disposed inside the housing 1. The control structure 3 includes a control circuit board 31 and a push switch 32. The push switch 32 is located at the bottom of the rotating clamp 22 and is wired to the control circuit board 31.

[0043] The housing 1 is divided into two parts, front and back, and the two housings 1 are fixed together by screws, and the appearance is similar to the shape of a pistol.

[0044] The plug structure 2 is mainly used for interface connection with new energy vehicles. The outside of the plug 21 is slidably connected to the right side of the inside of the housing 1, allowing it to slide horizontally inside. When in use, it retracts into the inside of the housing 1, and when not in use, it extends to the right side of the housing 1, thus providing good protection for the plug 21. The connecting groove 26 on the top of the plug 21 is adapted to the protrusion on the top of the inner wall of the housing 1. The two slide together, allowing the top of the plug 21 to maintain a stable connection with the housing 1. The bottom of the plug 21 is fixedly connected to the sliding block 24, and the sliding block 24 is slidably connected to the outside of the sliding rod 23, limiting the bottom of the plug 21 and allowing it to be positioned within the housing 1. The internal horizontal direction is stable for sliding, while the elastic element 25 is located between the sliding block 24 and the inner wall of the housing. It mainly provides elastic support for the left side of the sliding block 24. When the plug 21 retracts into the housing 1, it can simultaneously squeeze the elastic element 25 to retract. When the plug 21 unfolds outward, the elastic force of the elastic element 25 can push the sliding block 24 outward in the horizontal direction, thereby driving the plug 21 to extend outward. In order to avoid the sliding block 24 being affected by the elastic force of the elastic element 25, a rubber layer is provided on its right side, which mainly plays a buffering role, preventing wear when the right side of the sliding block 24 contacts the inner wall of the housing 1, and keeping the plug 21 in stable movement.

[0045] The connecting groove 26 is provided with a trapezoidal protrusion that matches the right end of the rotating clip 22. When the plug 21 retracts into the housing 1, the protrusion can press the right side of the rotating clip 22 and make it rotate upward, eventually engaging with the protrusion. At this time, under the engaging action of the rotating clip 22, the plug 21 can remain stable and retract into the housing 1. The button 27 connected to the left end of the rotating clip 22 is located at the top of the housing 1 in the normal state. When it is necessary to unfold the plug 21, simply press the button 27 downward manually to drive the rotating clip 22 to rotate, eventually separating its right end from the connecting groove 26.

[0046] The control structure 3 is mainly used to control the start-up of the entire charging gun. The control circuit 31 serves as the control center, and the push switch 32 is used to activate the control circuit 31. By being positioned on the left side of the bottom of the rotating clamp 22, when the rotating clamp 22 rotates, its bottom can squeeze the push switch 32, thereby opening the push switch 32. Then, the control circuit 31 starts to operate, enabling the charging gun to normally deliver electrical energy to the new energy vehicle. This allows the plug 21 to unfold and the charging gun to open simultaneously, achieving a one-step operation.

[0047] A rubber layer is provided on the right side of the sliding block 24, and the outside of the sliding block 24 is slidably connected to the bottom of the inner wall of the housing 1.

[0048] A sliding groove adapted to the sliding block 24 is provided at the bottom right side of the inner wall of the housing 1, which can effectively limit the sliding block 24 and allow it to slide stably inside the sliding block 24.

[0049] The left side of the plug 21 is wired to the control circuit board 31, and the top of the inner wall of the housing 1 is slidably connected to the inside of the connecting groove 26.

[0050] The plug 21 is wired to the control circuit board 31, enabling the transmission of electrical energy to the new energy vehicle and completing the charging process.

[0051] The right side of the plug 21 extends from the inside of the housing 1 to the right side of the housing 1, and the top of the button 27 extends from the inside of the housing 1 to the top of the housing 1.

[0052] The control circuit board 31 is fixedly installed in the middle of the inside of the housing 1, and the push switch 32 is fixedly installed in the upper part of the inside of the housing 1.

[0053] The control structure 3 is mainly used to control the opening of the charging gun and the normal power supply to the new energy vehicle. When the push switch 32 is pressed, it can open the control circuit board 31, thereby putting the charging gun into operation. When the push switch is pressed again, it will close the control circuit board 31, thereby putting the charging gun into a power-off state, increasing the safety of the charging gun during use.

[0054] A connecting wire 33 is connected to the left side of the control circuit board 31, and one end of the connecting wire 33 is connected to the output end of the charging pile.

[0055] The connecting wire 33 is connected to the output end of the charging pile, enabling the charging gun to be used with the charging pile.

[0056] The connecting wire 33 is fitted with a fixing member 34, which is snapped into the left side of the housing 1.

[0057] The fastener 34 is mainly used to limit and fix the connecting wire located on the left side of the housing 1, so as to prevent the connecting wire 33 from being pulled and becoming loose from the control circuit board 31 when the charging gun is used.

[0058] The working principle of the integrated European standard charging gun for new energy electric vehicles provided by this invention is as follows:

[0059] When in use, by manually pressing down button 27, the rotating clip 22 rotates inside the housing 1, and its right end separates from the connecting groove 26 at the top of the plug 21. At this time, under the elastic force of the elastic member 25, the sliding block 24 can be pushed to move horizontally, thereby driving the plug 21 to extend to the right side of the housing 1 until the right side of the sliding block 24 moves to fit against the right side of the inner wall of the housing 1. At this time, the plug 21 is fully unfolded.

[0060] While the rotating card 22 is rotating, its bottom left side can press down on the switch 32, thereby activating the control circuit board 31. At this time, the entire charging gun is in operation. Finally, the plug 21 is plugged into the new energy vehicle interface. Since the left side of the plug 21 is in contact with the right side of the rotating card 22, the plug 21 will not move when connected to the interface, and the connection is completed normally, thereby realizing the charging of the new energy vehicle.

[0061] When charging is complete, unplug the plug 21 and press the button 27 down again to make the rotating latch 22 rotate again and separate from the left side of the plug 21. Then press the plug 21 to the left to make it retract into the housing 1, and at the same time drive the sliding block 24 to press the elastic member 25 to the left until the plug 21 is completely retracted into the housing 1. Stop pressing the button 27, and under the elastic force of the support spring 28, the button 27 can be reset. At the same time, when the rotating latch 22 rotates, the press switch 32 is pressed again, which makes the control circuit board 31 close, and the charging gun is powered off.

[0062] Compared with related technologies, the integrated European standard charging gun for new energy electric vehicles provided by this invention has the following beneficial effects:

[0063] The plug structure 2 is mainly used for connection with the interface of new energy vehicles, enabling the charging gun to connect with the new energy vehicle. In conjunction with the control structure 3, when in use, simply pressing down the button 27 can realize two functions: starting the charging gun and automatically popping out the plug 21. After use, the plug 21 can be retracted to turn off the charging gun, changing the traditional separate operation method and realizing one-step operation. It can also effectively prevent the charging gun from being forgotten to be turned off, further increasing the safety of the charging gun, and making it more convenient and easier to use. At the same time, by setting the retractable plug 21, it can automatically pop out when in use and retract into the shell 1 when not in use. It is very simple and convenient in actual operation, and can isolate itself from the external environment, thus playing a protective role.

[0064] Second Embodiment

[0065] See also Figure 5 and Figure 6Based on the first embodiment of the present invention, an integrated European standard charging gun for new energy electric vehicles is provided. The second embodiment of the present invention provides another integrated European standard charging gun for new energy electric vehicles. The second embodiment does not prevent the independent implementation of the technical solution of the first embodiment.

[0066] Specifically, the present invention provides another integrated European standard charging gun for new energy electric vehicles, which differs in that:

[0067] It also includes a cable winding structure 4 installed on the charging pile 1a. The cable winding structure 4 includes a winding shell 41 and a sliding switch 46. The winding shell 41 is fixedly installed on the outside of the charging pile 1a by screws. The sliding switch 46 is installed on the top of the shell 1 and is wired to the control circuit board 31.

[0068] The winding shell 41 is rotatably connected to a winding reel 42. The connecting wire 33 is wound around the outside of the winding reel 42. A micro motor 43 is fixedly installed inside the winding shell 41. A transmission wheel 44 is fixedly installed on one side of both the micro motor 43 and the winding reel 42. The two transmission wheels 44 are connected by a transmission belt.

[0069] A battery 45 is fixedly installed on the left side of the inner wall of the winding shell 41. The battery 45 is wired to the micro motor 43, and the control circuit board 31 is signal-connected to the micro motor 43.

[0070] The winding structure 4 is mainly used to wind up the connecting wire 33. The winding shell 41 is fixedly installed on the outside of the charging pile 1a to avoid the tension on the connecting wire 33. The winding wheel 42 can rotate freely inside the winding shell 41. By winding the connecting wire 33 around the outside of the winding wheel 42, the connecting wire 33 can be lengthened and shortened when the winding wheel 42 rotates. The micro motor 43 is located on the left side inside the winding shell 41. It is a forward and reverse motor. It is connected to the battery 45 by wire to provide it with power. At the same time, it can be controlled to rotate by signal connection with the control circuit board 31. The slide switch 46 is used to send start, forward rotation and reverse rotation commands to the control circuit board 31 for the micro motor 43. The rotation of the micro motor 43 can make the two transmission wheels 44 rotate, which can drive the winding wheel 42 to rotate, thereby realizing the lengthening and winding of the connecting wire 33.

[0071] The winding structure 4 is mainly used to wind up the connecting wire 33. When not in use, the connecting wire 33 is wound up on the outside of the winding wheel 42, so that it is inside the winding shell 41 and isolated from the external environment, thus avoiding long-term exposure to the external environment and providing good protection for its exterior and extending its service life. When in use, it is only necessary to push the sliding switch 46 to make the micro motor 43 drive the winding wheel 42 to wind up the connecting wire 33, which is very convenient and simple to use.

[0072] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
