DETAILED DESCRIPTION

[0052] 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.

[0053] In order to solve the problem that when the existing charging gun is charging a vehicle, water enters between the charging gun and the charging port of the vehicle, causing corrosion and rust, thereby reducing the contact performance of the charging gun and affecting the charging efficiency. For this purpose, a new charging gun is designed. The core of the new charging gun is to implement effective sealing treatment between the vehicle charging port and the charging gun before each charging operation starts to prevent the intrusion of moisture from the external environment, thereby greatly improving the reliability and durability of the charging gun and ensuring the efficiency and safety of the charging process.

[0054] Example 1: A regional management stress cooling high-efficiency temperature-controlled liquid cooling charging pile, such as Figure 1-Figure 8As shown, it includes: a charging pile box 10; a charging gun 11 is placed in the charging pile box 10, a temperature sensor is arranged in the charging gun 11, and a connecting line 12 is fixedly connected between the charging gun 11 and the charging pile box 10; a fixed disk 13, which is arranged on the charging gun 11; a limiting member 14, which is fixedly connected to the fixing disk 13, and a first protective cover 15 is fixedly connected to the limiting member 14, and a first fixing ring 16 is fixedly connected to the side of the first protective cover 15 away from the limiting member 14; a charging head 17, which is detachably connected to the charging gun 11, and the charging head 17 is electrically connected to the connecting line 12, and the temperature sensor in the charging gun 11 is used to monitor the temperature of the charging head 17; a sealing component, which is arranged on the fixing disk 13, and is used to make the charging head 17 maintain its sealing with the vehicle during the charging process; a cooling component, which is arranged on the connecting line 12, and is used to cool the charging head 17.

[0055] In the above scheme, the charging gun 11 is composed of two shells, which are connected by bolts. The temperature sensor in the charging gun 11 is located on the upper side of the charging head 17. The temperature sensor in the charging gun 11 is used to monitor the temperature of the charging head 17. The medium used for connecting electricity in the connecting line 12 is a battery cell. In this embodiment, the battery cell in the connecting line 12 is used to connect the charging head 17 and the charging pile box 10. The limiter 14 is composed of two connecting rings and multiple bolts. The left side of the first protective cover 15 is made of soft material, and the middle and right sides of the first protective cover 15 are both made of plastic transparent material (the description of the material here is only taken as an example, not a limitation, and different materials can be replaced according to actual conditions).

[0056] like Figure 4-Figure 6 As shown, a plurality of arc-shaped pieces 20 are fixedly connected to a side of the first protective cover 15 facing away from the limiting member 14 , and arc-shaped trapezoidal notches are arranged on the plurality of arc-shaped pieces 20 , and the upper bottoms of the trapezoidal notches face the limiting member 14 .

[0057] In the above scheme, the arc-shaped sheet 20 and the first fixing ring 16 are both made of soft deformable materials. The left sides of the arc-shaped sheet 20 and the first fixing ring 16 have magnetic force (a magnet sheet can be fixedly connected). The trapezoidal notch on the arc-shaped sheet 20 is used to adapt to the curvature of different vehicle charging port positions and can quickly contact the position of the vehicle charging port.

[0058] like Figure 2-Figure 5 As shown, the sealing assembly includes: a second protective cover 30, which is fixed to the limiting member 14, and there is a gap between the second protective cover 30 and the first protective cover 15; an elastic airbag 31, which is arranged on the limiting member 14, and the elastic airbag 31 is fixed with a connecting pipe connected to the gap between the second protective cover 30 and the first protective cover 15, and the second protective cover 30 is fixed with an elastic member 32 on the side away from the limiting member 14, and the elastic member 32 is a hollow ring, and the cross-section of the elastic member 32 is elliptical.

[0059] In the above scheme, the left side of the second protective cover 30 is made of soft material, and the middle and right sides of the second protective cover 30 are made of transparent plastic material. When the elastic airbag 31 is squeezed, the gas in the elastic airbag 31 enters the gap between the second protective cover 30 and the first protective cover 15 through the connecting tube, and is finally ejected from the two to achieve the discharge of the gas in the gap between the second protective cover 30 and the first protective cover 15. The negative pressure environment presented at the gap between the second protective cover 30 and the first protective cover 15 is enhanced by the tendency of the elastic airbag 31 to deform and reset, thereby enhancing the fixing effect of the second protective cover 30 and the first protective cover 15 when they are in contact with the vehicle charging port. The shape of the elastic member 32 is defined to enable the elastic member 32 to be blown by the gas blown out from the gap between the second protective cover 30 and the first protective cover 15, so that the elastic member 32 can be quickly reset when reset to present Figure 5 status in .

[0060] like Figure 7-Figure 9 As shown, the cooling component includes: a second fixed ring 41, which is arranged in the charging gun 11 and fixedly connected to the charging head 17, there is a gap between the charging gun 11 and the second fixed ring 41, and a liquid infusion tube 40 is fixedly connected in the connecting line 12 and wound around the gap between the charging gun 11 and the second fixed ring 41, and the part of the liquid infusion tube 40 located in the gap between the charging gun 11 and the second fixed ring 41 is spiral, and a cooling circulation device connected to the liquid infusion tube 40 is arranged in the charging pile box 10.

[0061] In the above scheme, the infusion tube 40 is filled with silicone oil (this material limitation is only an example and not a limitation) when in use, and the silicone oil in the infusion tube 40 is made to flow through the cooling circulation equipment (existing mechanism, not shown in the figure) in the charging pile box 10. The flow of silicone oil in the infusion tube 40 is used to take away the heat around the charging head 17 to achieve liquid cooling of the charging head 17.

[0062] Working principle: After the construction of the charging station is completed, the staff will electrically connect all the charging piles in the charging station to achieve centralized control of the unified management and scheduling of multiple charging piles (to achieve the effect of regional management). This management mode has the following benefits:

[0063] 1. Resource optimization: intelligently allocate charging resources according to vehicle demand and grid load to improve charging efficiency;

[0064] 2. Remote monitoring: Support remote monitoring and maintenance, reduce the number of on-site inspections, and reduce operation and maintenance costs;

[0065] 3. Fault warning: Real-time monitoring of charging pile status, timely detection and handling of faults, and improvement of system reliability and safety.

[0066] When the vehicle needs to be charged, the user removes the charging gun 11 from the charging pile box 10, and then moves the charging gun 11 to the right side of the vehicle charging port. During this process, the left sides of the first protective cover 15, the first fixing ring 16 and all the arc-shaped pieces 20 are deformed to adapt to the curvature of the vehicle charging port. When the charging gun 11 drives the second protective cover 30 and the elastic member 32 to move to the left side of the elastic member 32 and contact the position of the vehicle charging port, the left sides of the first protective cover 15, the first fixing ring 16 and all the arc-shaped pieces 20 have been in contact with the position of the vehicle charging port. Under the action of the magnetic force of the first fixing ring 16 and the arc-shaped piece 20, they are adsorbed on the position of the vehicle charging port to achieve pre-fixation of the first protective cover 15 and its accessories, and to achieve shielding of the vehicle charging port.

[0067] When the position of the vehicle charging port contains an arc, the user needs to place all the arc sheets 20 at the arc of the vehicle charging port. Under the action of the magnetic force of the arc sheet 20 itself, the right side of the arc sheet 20 is deformed and the left side is adsorbed to the position of the vehicle charging port. Under the action of the trapezoidal notch of the arc sheet 20, the arc sheet 20 can be quickly deformed and quickly fit the position of the vehicle charging port.

[0068] When all the arc-shaped sheets 20 are fitted with the vehicle charging port, the elastic member 32 is also fitted with the position of the vehicle charging port (the elastic member 32 is deformed during the fitting process). At this time, the user squeezes the elastic airbag 31, and the elastic airbag 31 contracts and allows the gas inside to enter the gap between the second protective cover 30 and the first protective cover 15 through the connecting pipe, and then be discharged to the left through the gap between the second protective cover 30 and the first protective cover 15. During the exhaust process, the elastic member 32 temporarily breaks away from the position of the vehicle charging port.

[0069] When the gas in the elastic airbag 31 is discharged, the gas in the gap between the second protective cover 30 and the first protective cover 15 no longer squeezes the elastic member 32, and the elastic member 32 is then reset and resumes its fit with the vehicle charging port. Under the action of the elastic force of the elastic airbag 31 itself, the elastic airbag 31 draws the gas in the gap between the second protective cover 30 and the first protective cover 15 through the connecting tube, reduces the pressure in the gap between the second protective cover 30 and the first protective cover 15 to make it a negative pressure state, and through the negative pressure state in the gap between the second protective cover 30 and the first protective cover 15, the negative pressure fixation of the vehicle charging port is achieved, thereby enhancing the fit strength between the first protective cover 15 and the left side of the second protective cover 30 and the vehicle charging port.

[0070] After the left sides of the first protective cover 15 and the second protective cover 30 are fitted to the position of the vehicle charging port, the position of the vehicle charging port is covered to effectively block the intrusion of moisture from the external environment.

[0071] After covering the charging port of the vehicle, the user controls the vehicle to open the cover of the charging port, and then the user holds the charging gun 11 and inserts the charging head 17 into the charging port of the vehicle. The staff then controls the charging pile box 10, and the charging pile box 10 transmits electricity to the vehicle through the connecting line 12 and the charging head 17.

[0072] During the process of the charging head 17 transmitting electricity, the temperature sensor in the charging gun 11 continuously monitors the heat of the charging head 17. When the temperature sensor in the charging gun 11 detects that the temperature of the charging head 17 has increased, the cooling circulation equipment in the charging pile box 10 is quickly started, and the silicone oil in the infusion tube 40 is circulated and cooled by the cooling circulation equipment. The silicone oil in the infusion tube 40 can achieve heat exchange with the charging gun 11 during the circulation process, so as to cope with the heating of the charging gun 11, and cool the charging gun 11 by liquid cooling, thereby extending the service life of the charging gun 11. Through the above steps, stress cooling of the charging head 17 is achieved, and real-time monitoring of the charging head 17 by the temperature sensor in the charging gun 11 is achieved to control the temperature around the charging head 17.

[0073] After the vehicle is charged, the user squeezes the second protective cover 30 to change the pressure in the gap between the second protective cover 30 and the first protective cover 15, thereby releasing the negative pressure fixation of the vehicle by the second protective cover 30 and the first protective cover 15. At this time, the elastic airbag 31 automatically resets, and then the user pulls out the charging gun 11 until the charging head 17 is no longer in contact with the charging port of the vehicle. Finally, the user pulls out the charging gun 11 until the arc piece 20 and the first fixing ring 16 are no longer attached to the charging port of the vehicle (after the charging gun 11 is pulled out, place the charging gun 11 in the Figure 1 status in the .

[0074] Embodiment 2: Based on embodiment 1, Figure 8 , Fig.10 and Fig.11 As shown, it also includes: a connecting component, which is arranged in the charging gun 11 and is used for electrically connecting the connecting wire 12 and the charging head 17. The connecting component includes: a first connecting member 50, which is fixed in the charging gun 11 and electrically connected to the connecting wire 12; a second connecting member 51, which is slidably connected to the charging gun 11 and the first connecting member 50, and is electrically connected to the charging head 17, and the second connecting member 51 is electrically connected to the first connecting member 50; a limiting component, which is arranged in the charging gun 11 and is used to limit the second connecting member 51, and a cavity is provided in the second connecting member 51, and an inclined surface is provided on the side of the first connecting member 50 close to the second connecting member 51 and in the second connecting member 51, and the inclined surface on the first connecting member 50 is in contact with the inclined surface in the second connecting member 51, and the width of the first connecting member 50 close to the second connecting member 51 is smaller than the width of the cavity in the second connecting member 51, and the side of the first connecting member 50 close to the charging head 17 is sprayed with an insulating coating.

[0075] In the above scheme, the second electrical connector 51 and the first electrical connector 50 are both made of conductive materials, and an active connection between the two is adopted here, so that when an unexpected situation occurs, the charging head 17 can actively disconnect the physical connection between the second electrical connector 51 and the charging head 17, so that the second electrical connector 51 no longer transmits power to the charging head 17. The left side of the first electrical connector 50 is located in the cavity of the second electrical connector 51. When the left side of the first electrical connector 50 is attached to the second electrical connector 51, the inclined surface in the first electrical connector 50 does not contact the inclined surface of the second electrical connector 51. At this time, the second electrical connector 51 is not electrically connected to the first electrical connector 50. Conversely, when the inclined surface of the first electrical connector 50 contacts the inclined surface in the second electrical connector 51, the second electrical connector 51 is electrically connected to the first electrical connector 50.

[0076] like Figure 8 , Fig.10 and Fig.11 As shown, the limiting assembly includes: a first spring telescopic rod 60, fixedly connected to the charging gun 11; a fixed block 61, fixedly connected to the telescopic end of the first spring telescopic rod 60 and the second connecting member 51; a spring pin 62, fixedly connected to the charging gun 11, and the spring pin 62 is used to limit the fixing block 61; a driving assembly, arranged on the charging gun 11, used to drive the telescopic end of the first spring telescopic rod 60 to move.

[0077] In the above scheme, the first spring telescopic rod 60 is initially in a stretched state. When the telescopic portion of the spring pin 62 no longer limits the fixed block 61, the first spring telescopic rod 60 can drive the second electrical connection part 51 to actively move away from the electrical connection with the charging head 17 through the fixed block 61.

[0078] like Figure 8 , Fig.10 and Fig.11 As shown, the driving assembly includes: a fixed shell 70, fixedly connected to the charging gun 11, and the elastic airbag 31 is in contact with the fixed shell 70; a second spring telescopic rod 71, fixedly connected in the fixed shell 70; a sliding frame 72, limitedly slidably connected in the fixed shell 70, the sliding frame 72 is fixedly connected to the telescopic end of the second spring telescopic rod 71, the volume of the elastic airbag 31 is larger than the volume of the space between the sliding frame 72 and the fixed shell 70, the fixed shell 70 is fixedly connected with a wire sleeve 73 that passes through the charging gun 11 and is fixed thereto, a wire core 74 is slidably connected in the wire sleeve 73, one end of the wire core 74 is fixedly connected to the sliding frame 72, and the other end of the wire core 74 is fixedly connected to the telescopic part of the spring pin 62.

[0079] In the above solution, the elastic airbag 31 is initially located on the upper side of the fixed shell 70, and the sliding frame 72 is initially located in the upper middle portion of the fixed shell 70, and the sliding frame 72 can only slide upward.

[0080] like Fig.10 and Fig.11 As shown, the sliding frame 72 is provided with a trapezoidal groove, the upper bottom of which faces the second spring telescopic rod 71 , and the trapezoidal groove in the sliding frame 72 contacts the elastic airbag 31 , which is used to squeeze the sliding frame 72 .

[0081] In the above solution, the trapezoidal groove on the sliding frame 72 facilitates the elastic airbag 31 to enter the fixed shell 70 .

[0082] Before charging the vehicle and after the first fixing ring 16 is fixed, the staff squeezes the elastic airbag 31 and presses it downward so that the elastic airbag 31 can move downward along the trapezoidal groove of the sliding frame 72 during the contraction process. When the elastic airbag 31 is pressed into the fixing shell 70, the staff no longer squeezes the elastic airbag 31.

[0083] After completing the above operations, the charging pile box 10 transfers electricity to the charging head 17 through the battery cells in the connecting line 12, the first connecting piece 50 and the second connecting piece 51, and the charging head 17 transfers the electricity to the battery of the vehicle to charge the vehicle.

[0084] When the outside world is in a harsh environment with wind and rain, and the wind is strong enough to separate all the arc-shaped sheets 20 and the first fixing ring 16 from the vehicle charging port, the negative pressure fixation of the first protective cover 15 and the second protective cover 30 for the position of the vehicle charging port has failed. At this time, the elastic airbag 31 is reset, and the elastic airbag 31 first contacts the sliding frame 72 during the reset process.

[0085] When the squeezing force provided by the self-reset of the elastic airbag 31 is greater than the pulling force of the second spring telescopic rod 71 on the sliding frame 72, the elastic airbag 31 squeezes the sliding frame 72 upward (at this time, the telescopic part of the second spring telescopic rod 71 contracts), so that the sliding frame 72 pulls the wire core 74 upward. During the movement of the wire core 74, the telescopic part of the spring pin 62 is driven to move upward. After the telescopic part of the spring pin 62 moves until it no longer contacts the fixed block 61, the first spring telescopic rod 60 drives the second electrical connector 51 to move to the right through the fixed block 61, so that the second electrical connector 51 slides along the first electrical connector 50 and actively disconnects the electrical connection with the charging head 17. , so as to achieve physical power disconnection between the charging head 17 and the vehicle, and prevent the charging head 17 and the vehicle charging port from coming into contact with moisture when connected to electricity, thereby causing the current to pass through the electrolyte in the water to accelerate the corrosion of metal parts. Through the above steps, only the power disconnection between the charging head 17 and the vehicle charging port is achieved, and it will not affect the offset of the position of the charging head 17 and the vehicle charging port (when the left side of the first connecting member 50 is attached to the second connecting member 51, the inclined surface in the first connecting member 50 does not contact the inclined surface of the second connecting member 51. At this time, the second connecting member 51 is not electrically connected to the first connecting member 50, preventing the risk of electric shock in the future).

[0086] When it is necessary to disconnect the charging head 17 from the vehicle charging port, the user pulls out the charging gun 11 according to the steps mentioned in Example 1 and hands it over to the staff. At this time, the staff pulls out the elastic airbag 31 from the fixed shell 70, so that the elastic airbag 31 is in a Figure 8 and Fig. 9 status in .
