Description

Technical Field

[0001] The present invention relates to the field of new energy charging technology, and in particular to an automatic power distribution device for solar energy storage and charging. Background Art

[0002] The new energy charging pile is a type of solar storage charging. Because it has an automatic charging gun on its side, it is called an automatic distribution pile in most scenarios. Before construction, a base is installed on the open space, and the charging piles are fixed on the base one by one. A circulating refrigeration system is set up near the charging piles, and a set of refrigeration pipes is installed in each charging pile to cool the charging pile and prevent explosion.

[0003] When a charging pile with a refrigeration function is actually used, it only cools the main body (cabinet, pile), and does not take into account the cooling of the charging gun. The charging gun head will also generate high heat when it is inserted into the charging port of a new energy vehicle for charging. When high temperature is generated, the charging port will also be at risk. Therefore, how to apply the cooling effect to the charging gun when it is charging is a problem that needs to be solved in the current field of solar energy storage and new energy charging. Summary of the invention

[0004] In order to solve the above problem and enable the charging gun to be cooled during charging, the present invention provides the following technical solutions:

[0005] An automatic power distribution device for photoelectric storage and charging comprises a photoelectric storage and charging body and a charging gun connected to the photoelectric storage and charging body, wherein the photoelectric storage and charging body is provided with a refrigeration system, the refrigeration system comprises a refrigeration pipe filled in the space of the photoelectric storage and charging body, a plug connected to the inner cavity of the photoelectric storage and charging body is installed on the side of the photoelectric storage and charging body, the gun head of the charging gun is inserted into the plug, the wire part of the charging gun is connected to the charging system from the bottom of the photoelectric storage and charging body, and the cold air emitted by the refrigeration pipe into the photoelectric storage and charging body can act on the gun head through the plug, so that the gun head is continuously cooled; a branch pipe is connected to the pipeline of the refrigeration pipe, the other end of the branch pipe enters the plug and is provided with a support portion gradually inclined upward toward the outer end of the plug, and the inner end of the plug gradually tilts downward in a direction away from the support portion. A baffle is hinged on the bottom side of the inner end of the plug, and when the gun head is extended into the plug, the baffle is pushed to open. When the baffle is opened, the cold air in the solar storage body enters the plug; a knob-type valve is installed on the pipeline of the branch pipe, and a pull rod is connected to the baffle, and the other end of the pull rod is connected to the knob-type valve. When the baffle is opened from the inner end of the plug, the pull rod is used to drive the knob-type valve to close; when the baffle is closed from the inner end of the plug, the pull rod is used to drive the knob-type valve to open, and a hose is connected to the supporting part of the branch pipe, and the hose is fixed on the wire part of the charging gun, and the hose extends to the gun head along the length direction of the wire part, and one end of the hose extending to the gun head is aligned with the gun head.

[0006] As a further preferred embodiment, the refrigeration pipe is in a multi-section curved shape and is arranged in the solar storage and charging body. The air inlet and outlet ends of the refrigeration pipe both pass through the outside of the solar storage and charging body. A circulating refrigerator is provided outside the solar storage and charging body, and the air inlet and outlet of the circulating refrigerator are connected to the two ends of the refrigeration pipe.

[0007] As a further preferred embodiment, a hinge shaft is provided at the bottom of the inner end of the tube, the bottom end of the baffle is connected to the hinge shaft to be hinged with the inner end of the tube, a torsion spring is provided on the hinge shaft, one free end of the torsion spring is overlapped on the inner surface of the baffle, and the other free end of the torsion spring is overlapped on the bottom surface of the tube.

[0008] As a further preferred embodiment, when the gun head of the charging gun is inserted into the insertion tube, the inner surface of the baffle is in close contact with the charging port of the gun head, and the charging port of the gun head is covered by the inner surface of the baffle.

[0009] As a further preference, the partial section of the refrigeration tube close to the insert tube is in multiple sections vertically arranged on one side of the insert tube, and the distance between the multiple sections of bent tubes is closer. When the baffle is opened, the gun head is exposed on one side of the multiple sections of bent tubes.

[0010] As a further preferred embodiment, the supporting portion of the branch tube entering the cannula is further provided with an L-shaped bending portion, and the bending portion is perpendicular to the side direction of the cannula. When the gun tip is inserted into the cannula, the bottom surface of its tail falls on the bending portion to form a support, and the interface of the hose is connected to the vertical end of the bending portion.

[0011] As a further preferred embodiment, the hose extends to one end of the gun head and is equipped with a plurality of nozzles, the spraying direction of which faces the gun head, and a U-shaped notch is provided at the bottom of the outer end of the cannula. The hose extends to one end of the gun head and is stuck in the notch when the gun head is inserted into the cannula.

[0012] As a further preferred embodiment, a sink cavity is provided on the gun head, and the sink cavity is opened upward from the bottom surface of the gun head to the half of the gun head, and the nozzle follows the extended end of the hose and extends into the sink cavity, and a cooling space is formed between the nozzle and the cavity surface of the sink cavity.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. When the button valve is closed by the pull rod, the cold air in the refrigeration pipe is restricted from blowing into the support part through the branch pipe, and will not enter the hose from the support part, nor will it blow to the gun head from the end of the hose. The refrigeration gas is limited to circulating in the refrigeration pipe, and is used for cooling the photovoltaic storage and charging body and the electrical components in the photovoltaic storage and charging body. However, when the baffle is deflected inward from the inner end of the plug tube by the impact of the gun head, the side of the plug tube will be connected to the photovoltaic storage and charging body, and some cold air will pass through the baffle and the plug tube into the plug tube. This part of the gas can still be used to cool the gun head. The purpose is: in summer, when the user takes the gun head to charge, the surface of the gun head is cool, which improves the comfort and prevents the gun head from being deformed or scalded due to high temperature or exposure to the sun.

[0015] 2. A baffle is rotatably arranged at the inner end of the insert tube, a connecting rod is arranged on the side of the baffle, a branch pipe is arranged on the refrigeration pipe, a hose is arranged on the air outlet end of the branch pipe, the other end of the hose is connected to the charging head along the charging line, a knob-type valve is arranged on the branch pipe, and one end of the connecting rod is connected to the knob of the valve. When the gun head is taken to charge and the gun head is removed from the insert tube, the baffle will automatically rotate to close the inner end of the insert tube under the action of the torsion spring. At this time, the cold air in the light storage and charging body will not enter the insert tube due to the inward opening of the baffle, thereby avoiding waste of cold air. At this time, when the baffle is closed, the push rod will be used to drive the knob valve to rotate, so that the knob valve will automatically open, and a part of the cold air in the refrigeration pipe will be blown into the support part through the branch pipe, and then enter the hose from the support part. Since the gun head is inserted into the charging port of the car during charging, and the gun head will also bring the nozzle part of the hose into the charging port of the car, the sprayed cold air will blow to the gun head, so that the gun head can also be cooled while charging. The refrigeration medium is cold air, and the cold air is provided by the hose, and the cold air in the hose comes from the refrigeration pipe, and the refrigeration pipe is the built-in refrigeration component in the light storage and charging body. Therefore, the existing refrigeration source is not only used when the gun head is inserted into the insertion tube for storage when not charging, but also expanded to be applied to the synchronous cooling achieved when the gun head charges the car.

[0025] The above and other embodiments and advantages of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0026] In one embodiment, Figure 1-Figure 8 As shown: This embodiment provides an automatic power distribution device for solar storage and charging, including a solar storage and charging body 1 and a charging gun 2 connected to the solar storage and charging body 1. A refrigeration system is provided in the solar storage and charging body 1. The refrigeration system includes a refrigeration pipe 3 filled in the space of the solar storage and charging body 1. The refrigeration pipe 3 is in a multi-section curved shape and is arranged in the solar storage and charging body 1. The air inlet and air outlet ends of the refrigeration pipe 3 both pass through the outside of the solar storage and charging body 1. A circulating refrigerator is provided outside the solar storage and charging body 1, and the air inlet and outlet of the circulating refrigerator are connected to the two ends of the refrigeration pipe 3.

[0027] The side of the solar storage charging body 1 is equipped with a plug 4 connected to its inner cavity. When not charging, the gun head 5 of the charging gun 2 is pressed Figure 1The charging gun 2 is inserted into the insert tube 4 as shown, and the wire part of the charging gun 2 is connected to the charging system from the bottom of the solar storage and charging body 1. The cold air emitted by the refrigeration tube 3 cools down the various components in the solar storage and charging body 1 and the solar storage and charging body itself. When the gun head 5 is idle in the insert tube 4, the cold air will also enter the insert tube 4 to cool down the gun head 5. At this time, since the gun head 5 is idle (when not charging the car, the gun head 5 is inserted in the insert tube 4 and is idle), the charging pile is also in a non-working state. Under normal circumstances, the refrigeration tube 3 does not perform cooling operations. However, when summer comes, the solar storage and charging body 1 will generate high temperature under the action of light. An automatic module is arranged in the solar storage and charging body 1, such as a controller, a temperature controller, etc. When the temperature of the solar storage and charging body 1 exceeds the set temperature, the refrigeration system will be automatically started to provide cold air to the refrigeration tube 3. At this time, part of the cold air enters the insert tube 4 to cool down the gun head 5.

[0028] like Figures 2 to 4 As shown, a branch pipe 6 is connected to the pipeline of the refrigeration pipe 3, and the other end of the branch pipe 6 enters the insert pipe 4 and is provided with a support portion 7 which is gradually inclined upward toward the outer end of the insert pipe 4. The support portion 7 is an extension of the branch pipe 6 and is a molded tube integral with the branch pipe 6. The inner end of the insert pipe 4 gradually tilts downward in a direction away from the support portion 7. A baffle 8 is hinged on the bottom side of the inner end of the insert pipe 4. When the gun head 5 is extended into the insert pipe 4, the baffle 8 is pushed to open. When the baffle 8 is opened, the cold air in the light storage and charging body 1 enters the insert pipe 4;

[0029] like Figure 2 , Figure 5 As shown, a hinge shaft 12 is provided at the bottom of the inner end of the cannula 4, and the bottom end of the baffle 8 is connected to the hinge shaft 12 to realize hinge connection with the inner end of the cannula 4. A torsion spring 13 is provided on the hinge shaft 12, and one free end of the torsion spring 13 overlaps the inner surface of the baffle 8, and the other free end of the torsion spring 13 overlaps the bottom surface of the cannula 4. It can be seen that when the baffle 8 is hit by the gun head 5, in addition to being able to deflect backward from the bottom of the inner end of the cannula 4, when the gun head 5 is removed from the cannula 4, the baffle 8 will be reversely deflected to the rear end of the cannula 4 under the rebound effect of the torsion spring 13, and the rear end of the cannula 4 will be automatically closed.

[0030] like Figure 1 , Figure 2As shown, a knob-type valve 9 is installed on the pipeline of the branch pipe 6, a pull rod 10 is connected to the baffle 8, and the other end of the pull rod 10 is connected to the knob-type valve 9. When the baffle 8 is opened from the inner end of the insert tube 4, the pull rod 10 is used to drive the knob-type valve 9 to close; when the baffle 8 is closed from the inner end of the insert tube 4, the pull rod 10 is used to drive the knob-type valve 9 to open, and a hose 11 is connected to the supporting portion 7 of the branch pipe 6. The hose 11 is fixed on the wire part of the charging gun 2, and the hose 11 extends to the gun head 5 along the length direction of the wire part, and one end of the hose 11 extending to the gun head 5 is aligned with the gun head 5. The support part 7 where the branch pipe 6 enters the insertion tube 4 is provided with an L-shaped bending part 14. The bending part 14, the support part 7 and the branch pipe 6 are a bent pipe structure formed at one time. The bending part 14 is vertical to the side direction of the insertion tube 4. When the gun head 5 is inserted into the insertion tube 4, the bottom surface of its tail falls on the bending part 14 to form a support, and the interface of the hose 11 is connected to the vertical end of the bending part 14. It needs to be further explained here that the air inlet end of the hose 11 is connected to the bending part 14 (actually connected to the branch pipe 6), the pipeline of the hose 11 extends along the length of the charging cable and is fixed to the charging cable at the same time, and the air outlet at the end of the hose 11 reaches the bottom of the gun head 5 and is connected to the bottom surface of the gun head 5.

[0031] To sum up the principle: before the charging gun 2 is used for charging the car, its gun head 5 is idle in the insert tube 4. At this time, the bottom surface of the gun head 5 is supported on the support part 7. After being tilted and supported by the support part 7, the charging joint part of the gun head 5 hits the baffle 8. The baffle 8 deflects inward under the impact of the charging joint of the gun head 5, that is, at this time, the inner end of the insert tube 4 is opened, and the lumen of the insert tube 4 will be connected with the inner lumen of the light storage charging body 1. The cold air provided by the refrigeration tube 3 to the light storage charging body 1 will enter the insert tube 4 to cool the gun head 5. It can be seen from this that whether the cold air in the light storage charging body 1 can enter the insert tube 4 depends on whether the gun head 5 is inserted (idle) in the insert tube 4. If the gun head 5 is plugged into the car charging port for charging, the gun head 5 will not be inserted (idle) in the insert tube 4, and the plug end of the gun head 5 will not hit the baffle 8, let alone open the baffle 8, and the cold air in the light storage charging body 1 will not enter the insert tube 4. In other words, when the gun head 5 charges the car, the cold air will not enter the insert pipe 4, and then be discharged outward through the insert pipe 4, resulting in waste.

[0032] The gun head 5 is inserted into the insertion tube 4. In addition to pushing the baffle 8 open, the baffle 8 will also drag the pull rod 10 inward (the pull rod 10 can also be a connecting rod structure, and the other end of the connecting rod structure is hinged to the knob of the knob valve 9 through an eccentric shaft). After the pull rod 10 drives the knob to rotate, the knob valve 9 is closed. At this time, the knob valve 9 is used to limit the cold air in the refrigeration pipe for circulation refrigeration. Most of it is used to cool the interior of the light storage and charging body 1. A small amount of cold air enters the insertion tube 4 to provide low temperature conditions for the gun head 5 in an exposed environment in summer, so as to avoid burning hands when holding it for charging. At this time, the cold air will not enter the branch pipe 6, nor will it enter the support part 7 from the branch pipe 6, nor will it enter the hose 11 from the support part 7, and it will not blow to the gun head 5 from the air outlet at the end of the hose 11. On the contrary, when the gun head 5 is taken away from the insertion tube 4 and the gun head 5 is inserted into the charging port of the car for charging, the gun head 5 no longer pushes the baffle 8. The baffle 8 will automatically rotate to the inner end of the insertion tube 4 under the rebound action of the torsion spring 13 to close the inner end of the insertion tube 4. At this time, the cold air in the light storage and charging body 1 will not enter the insertion tube 4 due to the opening of the baffle 8. Since the gun head 5 is no longer in the insertion tube 4 at this time, there is no need for cold air to enter the insertion tube 4, and there is no need to keep the gun head 5 at a low temperature in the insertion tube 4. It can be seen that when the gun head 5 is separated from the insertion tube 4, the inner end of the insertion tube 4 will be automatically closed, which can avoid the waste of cold air.

[0033] When the baffle 8 is closed, it will push the pull rod 10 to drive the knob to rotate in the opposite direction, so that the knob valve 9 is automatically opened. At this time, a part of the cold air in the refrigeration pipe 3 is blown into the support part 7 through the branch pipe 6, and then enters the hose 11 from the support part 7. Since the gun head 5 is inserted into the charging port of the car during charging, and the gun head 5 will also bring the nozzle part of the hose 11 into the charging port of the car, the cold air sprayed by the hose 11 is blown into the gun head 5 and the car charging port at the same time, so that the gun head 5 can also achieve automatic cooling when charging the car. The cooling medium used by the gun head 5 when charging in the car charging port is cold air, and the cold air is provided by the hose 11, and the cold air in the hose 11 still comes from the refrigeration pipe 3 in the light storage and charging body 1. Therefore, the present invention applies the existing cooling source in the light storage and charging body 1 not only to the gun head 5 when it is idle and stored in the insertion tube 4, but also after the hose 11 is expanded, the air source is applied to the gun head 5 to achieve synchronous cooling when charging the car.

[0034] Following the above, Figure 4As shown, a plurality of nozzles 15 are installed on one end of the hose 11 extending to the gun head 5, and the spray direction of these nozzles 15 faces the gun head 5. A U-shaped notch 16 is provided at the bottom of the outer end of the cannula 4. When the hose 11 extends to one end of the gun head 5 and the gun head 5 is inserted into the cannula 4, it is stuck in the notch 16. That is, a plurality of nozzles 15 are provided on the air outlet of the hose 11, and these nozzles 15 are used to blow air at the gun head 5 to cool the gun head 5. Since the spray intensity and the amount of air spray of the nozzle 15 are affected by the spray hole, the spray time can be extended, so that the sprayed cold air can extend the cooling time of the gun head 5.

[0035] like Figure 6 , Figure 7 As shown, a sink cavity 17 is provided on the bottom surface of the gun head 5, and the sink cavity 17 extends upward from the bottom surface of the gun head 5 to one-half of the gun head 5. The nozzle 15 follows the extension end of the hose 11 and extends into the sink cavity 17, so that the nozzle 15 is stored in the sink cavity 17. When the nozzle 15 is inserted into the charging port of the car with the gun head 5 for charging, since the nozzle 15 is stored on the gun head 5 through the sink cavity 17, even if the nozzle 15 exists, it will not affect the insertion of the gun head 5 into the charging port of the car. A cooling space is formed between the nozzle 15 and the cavity surface of the sink cavity 17. When the hose 11 sprays cold air, it is blown into the sink cavity 17 through the nozzle 15, and after being concentrated in the cooling space, it acts on the gun head 5 from the bottom, and the gun head 5 can better degrade the high temperature of the electric energy generated when the car is charged.

[0036] When the gun head 5 of the charging gun 2 is inserted into the insertion tube 4, the inner surface of the baffle 8 is closely attached to the charging port of the gun head 5, and the charging port of the gun head 5 is covered by the inner surface of the baffle 8. At this time, although cold air will enter the insertion tube 4, the cold air will not enter the charging port of the gun head 5, so as to prevent condensed water in the cold air from entering the charging port and causing the charging port to be wet.

[0037] The section of the refrigeration pipe 3 near the insertion tube 4 is in a multi-section vertical position on one side of the insertion tube 4, and the distance between the multi-section curved pipes is closer. When the baffle 8 is opened, the gun head 5 is exposed on one side of the multi-section curved pipe. Since the curved sections of the refrigeration pipe 3 near the insertion tube 4 are more concentrated, the cooling effect generated during the circulation refrigeration is more reflected near the insertion tube 4. When the gun head 5 is inserted into the insertion tube 4 and the baffle 8 at the inner end of the insertion tube 4 is opened, the cooling effect of the cold air entering the insertion tube 4 is better, so that the gun head 5 can be kept at a low temperature better.

[0038] The above orientation designations do not represent the specific orientations of the components in this implementation scheme. This implementation scheme is only for the convenience of describing the scheme, and the orientations are described relatively with reference to the figures. In essence, the specific orientations of the components are described according to their actual installation and actual use as well as the customary orientations of technicians in this field. This is hereby explained.

[0039] The specific implementation methods described above further describe the invention purpose, technical solutions, and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the protection scope of the present invention. It is particularly pointed out that for those skilled in the art, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
