During the charging process, the infrared smoke camera monitors the charging situation. When an abnormal situation occurs, such as high fever or fire, since the charging gun body and the new energy vehicle remain relatively fixed, the connecting block can be controlled to shrink into the receiving cavity to complete the disconnection work between the connecting block and the new energy vehicle. At the same time, the charging gun body can be connected and fixed to the charging terminal body through the adaptive limit component, which improves the charging safety of the charging terminal while improving the anti-theft performance.

The liquid-cooling return pipes are set into several groups, so that when the liquid-cooling cable is damaged, after the damaged liquid-cooling return pipe is closed, there is always a corresponding liquid-cooling return pipe to complete the liquid-cooling circulation work, which improves the liquid-cooling supercharging effect of the charging terminal while improving the functional stability of the liquid-cooling supercharging.

[0022] 3. By controlling the two sets of electric push rods to drive the two sets of sliders to rise, since the two sets of sliders are slidably connected in the slide groove, and the control board is threadedly connected to the fixed guide threaded rod, the control board will drive the spiral wire placement plate to rotate during the rising process, and slowly release the liquid cooling cable in the wire placement groove. When the liquid cooling cable retracts inward, the reverse control can be used to replace the liquid cooling cable in the spiral wire placement groove, avoiding the problem of cables piling up when storing cables in the existing cable storage structure, thereby avoiding the problem of heat accumulation and inconvenient heat dissipation when the liquid cooling cables are piled up, thereby improving the working stability of the charging terminal.

[0023] 4. By controlling the rotation of four sets of winding rollers, the four sets of winding rollers are in contact with the outer wall of the liquid-cooling cable. When rotating, they can drive the liquid-cooling cable to retract into the anti-stacking storage mechanism, avoiding the existing charging pile cables from being placed outside, reducing the risk of damage. At the same time, during the use of the charging terminal, when the personnel hold the induction charging gun to move the liquid-cooling cable, the first wire tube can follow the liquid-cooling cable to make corresponding angle adjustments under the action of several sets of reset springs, avoiding damage caused by excessive bending of the liquid-cooling cable during use, and improving the service life of the charging terminal.

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 shall fall within the scope of protection of the present invention.

[0037] The embodiment of the present invention provides an induction separation liquid cooling super charging terminal for new energy vehicles, including a charging terminal body 1.

[0039] The charging terminal of the present invention is designed to meet the following environmental parameters: operating temperature of -20°C to +50°C; transport or storage temperature of -30°C to +70°C; operating humidity of 5% RH to 95% RH (non-condensing); operating pressure of 80 kPa to 110 kPa; overvoltage category II; altitude of 2000 m; pollution resistance level 3; and impact energy of 20 J (5 kg, 0.4 m). After the test, performance must not be degraded, the IP rating must not be affected, the door's operating and locking points must not be damaged, and deformation that could cause contact between live parts and the housing must not occur.

[0040] Specifically, the power distribution module 801 can automatically allocate appropriate power according to vehicle needs. The control module 802 can monitor relevant data such as voltage, current, temperature and humidity in real time before and after charging of the new energy vehicle to ensure charging safety. The liquid cooling circulation module 804 can drive the coolant to flow through key components such as the power distribution module 801, liquid cooling cable 4 and inductive charging gun 5, efficiently taking away the heat generated by these components during the charging process, and maintaining the temperature at a low level during the charging process.

[0041] Specifically, during the use of the charging terminal, the personnel park the vehicle close to the charging terminal, and then unlock the inductive charging gun 5 by scanning a code or swiping a card, and then pick up the inductive charging gun 5 and connect it to the charging interface of the vehicle. During this process, the liquid cooling cable 4 can extend from the anti-stacking storage mechanism 9, and automatically adjust the length of the liquid cooling cable 4 according to usage requirements. The winding mechanism 6 can follow the movement of the liquid cooling cable 4 to avoid excessive bending of the liquid cooling cable 4. After completing charging, the personnel pull out the inductive charging gun 5 and replace it on the charging terminal body 1, thereby completing the charging work.

[0042] For example, Figure 3 As shown, the liquid-cooling cable 4 includes a protective layer 401; a liquid-cooling output pipe 402 is provided at the inner center of the protective layer 401; a metal heat-conducting sleeve 403 is sleeved on the outer wall of the liquid-cooling output pipe 402; a plurality of groups of grooves are distributed in a circular array on the outer wall of the metal heat-conducting sleeve 403; a group of conductor wires 404 are provided in each group of the grooves; a plurality of groups of liquid-cooling return pipes 405 are distributed in a circular array inside the protective layer 401; one end of each group of the conductor wires 404 is electrically connected to the inductive charging gun 5, and the other end is electrically connected to the power distribution module 801; one end of the liquid-cooling output pipe 402 and the plurality of groups of liquid-cooling return pipes 405 are connected to the liquid cooling circulation module 804, and the other ends are connected to each other through the inductive charging gun 5.

[0043] During the use of the charging terminal, the power distribution module 801 charges the new energy vehicle through several groups of conductor wires 404 and the inductive charging gun 5. During this process, the coolant enters the liquid cooling cable 4 through the liquid cooling output pipe 402, taking away the heat generated by the conductor wire 404 during the charging process. Then, after cooling the inductive charging gun 5, the coolant circulates back through several groups of liquid cooling return pipes 405, and several groups of conductor wires 404 are embedded on the outer wall of the metal thermal conductive sleeve 403, which increases the contact area and can utilize the thermal conductivity of the metal to achieve efficient heat dissipation. The liquid cooling return pipe 405 is set to several groups, so that when the liquid cooling cable 4 is damaged, after the damaged liquid cooling return pipe 405 is closed, there is always a corresponding liquid cooling return pipe 405 to complete the liquid cooling circulation work, which improves the liquid cooling supercharging effect of the charging terminal while improving the functional stability of the liquid cooling supercharging.

[0044] For example, Figure 4 and Figure 5As shown, the inductive charging gun 5 includes a charging gun body 501; a handle 502 is provided on the outer wall of the charging gun body 501; a charging head 503 is provided at one end of the charging gun body 501; a connecting block 504 is provided at the end of the charging head 503 away from the charging gun body 501; a plurality of connecting columns 505 are provided on the connecting block 504; an adaptive limit assembly 506 is sleeved on the outer wall of the charging head 503; a side wall of the charging head 503 away from the charging gun body 501 is opened. A receiving cavity 507 is provided; the connecting block 504 is movable through the receiving cavity 507; two groups of electric slides 508 are symmetrically provided on the inner walls on both sides of the receiving cavity 507; the output ends of the two groups of electric slides 508 are transmission-connected to the connecting block 504; a plurality of groups of conductive posts 509 are provided on the inner wall of the receiving cavity 507 on the side away from the connecting block 504; one end of each group of connecting posts 505 passes through the receiving cavity 507 and is movable through the corresponding group of conductive posts 509.

[0045] Specifically, the adaptive limit assembly 506 includes a mounting frame 5061; four groups of guide columns 5062 are symmetrically provided on both side walls of the mounting frame 5061; four groups of movable columns 5063 are symmetrically and movably penetrated on both side walls of the mounting frame 5061; each group of the movable columns 5063 is movable through a corresponding group of guide columns 5062; two groups of double-end motors 5064 are symmetrically provided in the mounting frame 5061; the output ends of each group of the double-end motors 5064 are respectively connected to two groups of screw rods 5065 for transmission; each group of the screw rods 5065 is threadedly connected to a corresponding group of movable columns 5063; each group of the movable columns 5063 is provided with a group of limit plates 5066 at the end away from the mounting frame 5061; each group of the limit plates 5066 is fan-shaped, and a number of groups of friction blocks 5067 are evenly distributed on the curved surface.

[0046] During the use of the charging terminal, the personnel opens the charging cover of the new energy vehicle, then holds the charging gun body 501 by the grip 502, inserts the connecting block 504 on the charging head 503 into the charging port of the new energy vehicle, and simultaneously controls the two sets of double-end motors 5064 to drive the four sets of screw rods 5065 to rotate. Under the threaded connection relationship between the screw rods 5065 and the movable columns 5063, the four sets of movable columns 5063 drive the four sets of limit plates 5066 to move toward the end away from the installation frame 5061, so that the curved surfaces of the four sets of limit plates 5066 contact the inner wall of the charging slot of the new energy vehicle to limit and fix the charging gun body 501, and the corresponding sets of friction blocks 5067 complete the extrusion to increase the friction force while avoiding damage to the body of the new energy vehicle;

[0047] Specifically, during the charging process, the infrared smoke camera 10 monitors the charging status. When an abnormal situation occurs, such as high fever or fire, since the charging gun body 501 and the new energy vehicle remain relatively fixed, the two sets of electric slides 508 can be controlled to drive the connecting block 504 to retract into the accommodating cavity 507, thereby completing the disconnection between the connecting block 504 and the new energy vehicle. In the process of extension and retraction of the connecting block 504, several sets of connecting columns 505 are always movable and penetrate the conductive column 509 to maintain electrical connection, and the charging gun body 501 has a built-in independent power supply to drive the corresponding structure, which can avoid the impact of charging abnormalities on the disconnection work. At the same time, when the charging terminal is idle, the charging gun body 501 can be fixed to the charging terminal body 1 through the adaptive limit component 506, thereby improving the charging safety of the charging terminal while improving the anti-theft performance.

[0048] For example, Figure 6 and Figure 7 As shown, the winding mechanism 6 includes a mounting block 601; a corrugated hose 602 is provided on a side wall of the mounting block 601 away from the charging terminal body 1; a movable through slot 603 is provided on the mounting block 601; a first wire tube 605 is provided in the movable through slot 603; the two ends of the first wire tube 605 are respectively movable through the corrugated hose 602 and the anti-stacking storage mechanism 9; a plurality of groups of return springs 604 are distributed in a circular array on the outer wall of the first wire tube 605; one end of each group of return springs 604 away from the first wire tube 605 is connected to the inner wall of the movable through slot 603; a group of winding blocks 606 are respectively provided at both ends of the first wire tube 605; a group of winding through slots 607 are provided on each group of winding blocks 606; two groups of winding rollers 608 are respectively provided in the vertical direction of the two groups of winding through slots 607.

[0049] After the charging terminal is used, the personnel reinserts the inductive charging gun 5 into the charging terminal body 1 and controls the four sets of winding rollers 608 to rotate at the same time. The four sets of winding rollers 608 are in contact with the outer wall of the liquid-cooling cable 4. When rotating, they can drive the liquid-cooling cable 4 to shrink into the anti-stacking storage mechanism 9, avoiding the existing charging pile cables from being placed outside, reducing the risk of damage. At the same time, during the use of the charging terminal, when the personnel holds the inductive charging gun 5 to drive the liquid-cooling cable 4 to move, the first wire tube 605 can follow the liquid-cooling cable 4 to make corresponding angle adjustments under the action of several sets of reset springs 604, avoiding damage caused by excessive bending of the liquid-cooling cable 4 during use, thereby improving the service life of the charging terminal.

[0050] For example, Figure 8 and Figure 9As shown, the anti-stacking storage mechanism 9 includes a storage box 901; a wire inlet hole 902 is provided on one side wall of the storage box 901; two groups of electric push rods 903 are symmetrically provided on the top of the storage box 901; a storage cavity 904 is provided in the storage box 901; a control panel 905 is provided in the storage cavity 904; a slide groove 906 is provided on the top of the control panel 905; the slide groove 906 is annular; two groups of sliders 907 are slidably connected in the slide groove 906; the output end of each group of the electric push rods 903 is movable and penetrates the storage cavity 904, and is transmission-connected to the corresponding group of sliders 907; a guide threaded rod 908 is provided in the storage cavity 904;

[0051] Specifically, the two ends of the guide thread rod 908 are respectively fixedly connected to the top and bottom inner walls of the storage cavity 904; the control board 905 is threadedly connected to the guide thread rod 908; a wire placement plate 909 is provided at the bottom of the control board 905; the wire placement plate 909 is arranged in a spiral shape; a wire placement groove 910 is provided at the top of the wire placement plate 909; two groups of heat dissipation holes 911 are evenly distributed at the bottom of the wire placement groove 910; a second wire tube 912 is provided at the end of the wire placement plate 909 away from the control board 905.

[0052] When the liquid-cooling cable 4 extends outward, the two sets of electric push rods 903 drive the two sets of sliders 907 to rise. Since the two sets of sliders 907 are slidably connected in the slide groove 906, and the control board 905 is threadedly connected to the fixed guide threaded rod 908, the control board 905 will drive the spiral wire placement plate 909 to rotate during the rising process, and slowly release the liquid-cooling cable 4 in the wire placement groove 910. When the liquid-cooling cable 4 contracts inward, reverse control can be used to replace the liquid-cooling cable 4 in the spiral wire placement groove 910, avoiding the problem of cables piling up in the existing cable storage structure when storing cables, thereby avoiding the problem of heat accumulation and inconvenience in heat dissipation when the liquid-cooling cables 4 are piled up, thereby improving the working stability of the charging terminal.

[0053] During the use of the charging terminal, the personnel open the charging cover of the new energy vehicle, and then insert the connecting block 504 on the charging head 503 into the charging interface of the new energy vehicle, and at the same time control the adaptive limit component 506 to press against the inner wall of the charging slot of the new energy vehicle to fix the charging gun body 501. During the charging process, the infrared smoke camera 10 monitors the charging status. When an abnormal situation occurs, such as high fever or fire, since the charging gun body 501 and the new energy vehicle remain relatively fixed, the connecting block 504 can be controlled to shrink into the receiving cavity 507 to complete the disconnection of the connecting block 504 and the new energy vehicle. At the same time, the charging gun body 501 can be connected and fixed to the charging terminal body 1 through the adaptive limit component 506, which improves the charging safety of the charging terminal while improving the anti-theft performance.

[0054] The coolant enters the liquid-cooled cable 4 through the liquid-cooling output pipe 402, takes away the heat generated by the conductor wire 404 during the charging process, and then circulates back through several groups of liquid-cooling return pipes 405. Several groups of conductor wires 404 are embedded on the outer wall of the metal heat-conducting sleeve 403, which increases the contact area and can utilize the thermal conductivity of the metal to complete efficient heat dissipation. The liquid-cooling return pipe 405 is set to several groups, so that when the liquid-cooling cable 4 is damaged, after the damaged liquid-cooling return pipe 405 is closed, there is always a corresponding liquid-cooling return pipe 405 that can complete the liquid cooling circulation work, which improves the liquid-cooling supercharging effect of the charging terminal and the functional stability of the liquid-cooling supercharging.

[0055] By controlling the two groups of electric push rods 903 to drive the two groups of sliders 907 to rise, since the two groups of sliders 907 are slidably connected in the slide groove 906, and the control board 905 is threadedly connected to the fixed guide threaded rod 908, the control board 905 will drive the spiral wire plate 909 to rotate during the rising process, and slowly release the liquid cooling cable 4 in the wire groove 910. When the liquid cooling cable 4 shrinks inward, reverse control can be used to replace the liquid cooling cable 4 in the spiral wire groove 910, avoiding the problem of cables piling up when the existing cable storage structure is stored, thereby avoiding the problem of heat accumulation and inconvenience in heat dissipation when the liquid cooling cable 4 is piled up, thereby improving the working stability of the charging terminal.

[0056] By controlling the rotation of the four sets of winding rollers 608, the four sets of winding rollers 608 come into contact with the outer wall of the liquid-cooling cable 4. When rotating, they can drive the liquid-cooling cable 4 to retract into the anti-stacking storage mechanism 9, avoiding the existing situation where all the charging pile cables are placed outside, reducing the risk of damage. At the same time, during the use of the charging terminal, when the person holding the inductive charging gun 5 drives the liquid-cooling cable 4 to move, the first wire tube 605 can follow the liquid-cooling cable 4 under the action of several sets of reset springs 604 to make corresponding angle adjustments, avoiding damage caused by excessive bending of the liquid-cooling cable 4 during use, thereby increasing the service life of the charging terminal.

[0057] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
