[0002] As the infrastructure for providing charging services for electric vehicles, the charging pile functions similarly to a gas station for traditional vehicles. The working principle of the charging pile is to convert the alternating current input from the three-phase power grid into direct current through a rectifying circuit, and then output the required direct current voltage through a power converter to charge the battery of the electric vehicle. With the rapid development of the new energy vehicle industry, the construction and demand for charging piles are also increasing day by day.

[0003] In the patent with the publication number CN117584780A, a temperature regulation device for an electric vehicle charging pile is disclosed. This device is the existing heat dissipation mechanism for charging piles. The existing heat dissipation mechanism for charging piles is relatively ordinary. During daily use, when the temperature of the charging pile body changes, the actual effect of the temperature regulation device is affected by the inside of the chassis. This makes the heat dissipation efficiency of the general heat dissipation mechanism unstable in different temperature environments, and there will be problems with poor heat dissipation effect in extreme temperature environments.

[0004] In summary, there is a problem in the prior art that the charging pile heat dissipation system cannot adaptively adjust the heat dissipation power according to its own temperature. Content of the Utility Model

[0013] When the rotating shaft rotates, it drives the shaft sleeve to move up and down.

[0014] Furthermore, the shaft sleeve is sleeved on the rotating shaft and is threadedly connected to the rotating shaft.

[0015] Furthermore, circular hinge holes are provided at both ends of the short rod. One end of the circular hinge hole is connected to the shaft sleeve, and the other end is connected to the eccentric end rod;

Detailed implementation mode

[0042] Embodiment 1

[0043] The present utility model provides an adaptive cooling type charging pile. Please refer to Figures 1 - 6 simultaneously, this charging pile includes a refrigeration cycle system 200 arranged below the chassis assembly 300, and an air outlet system 100 arranged below the refrigeration cycle system 200;

[0044] The air outlet system 100 includes an angle adjustment mechanism 110;

[0045] The angle adjustment mechanism 110 includes a bush 111, a short rod 112, an eccentric end rod 113 and a blade unit. One end of the short rod 112 is hinged to the bush 111, the other end of the short rod 112 is sleeved on the eccentric end rod 113, and the eccentric end rod 113 is connected to the eccentric position of the blade unit;

[0046] When the bush 111 moves up and down, the short rod 112 swings to drive the eccentric end rod 113 to rotate, and then drives the blade unit to deflect.

[0047] When the temperature changes in the chassis assembly 300 part, the temperature sensor connected to its outside first sends out a signal and transmits the signal to the first motor 115 in the angle adjustment mechanism 110. At this time, the first motor 115 responds, starts to work and drives the rotating shaft 114 in the angle adjustment mechanism 110 to rotate. At this time, the threaded bush 111 connected to the rotating shaft 114 starts to move up and down, driving the short rod 112 to drive the eccentric end rod 113 on the blade unit to rotate around the center of the blade unit fixed on the housing 121. At this time, a horizontal angle deflection occurs relative to the housing 121. This action is continuously carried out when the rotation mechanism 120 works and can be continuously adjusted according to the temperature change.

[0048] During the whole process, according to the continuous change of the temperature inside the machine body, the blades of the air outlet system continuously adjust the deflection angle, change the wind force of the heat dissipation system, and can realize that when the temperature changes, the heat dissipation system improves the heat dissipation efficiency through its own adjustment.

[0049] In order to enable the air outlet system 100 to adjust the blade 117, the angle adjustment mechanism 110 further includes a rotating shaft 114 and a first motor 115; the rotating shaft 114 is arranged inside the air outlet system 100, and the upper end of the rotating shaft 114 is connected to the first motor 115; the first motor 115 drives the rotating shaft 114 to rotate; when the rotating shaft 114 rotates, it drives the shaft sleeve 111 to move up and down. This angle adjustment mechanism 110 is a link mechanism. One end of the rotating shaft 114 has a keyway connected to the coupling. When the first motor 115 receives the signal sent by the sensor, the motor moves, and provides torque to the rotating shaft 114 through the coupling. In order to adapt to a certain torque, the cylinder diameters at both ends of the rotating shaft are smaller than the cylinder diameter in the middle, with a certain structural strength, and threads are machined on the middle cylinder surface.

[0050] In an alternative and more feasible solution of this embodiment, the shaft sleeve 111 is sleeved on the rotating shaft 114 and is threadedly connected to the rotating shaft 114. When the rotating shaft 114 rotates, the shaft sleeve 111 starts to move up and down relative to the housing 121 along the thread. There are multiple hinge slots on the shaft sleeve 111, and the number of hinge slots is the same as the number of short rods 112 and blade units.

[0051] Among them, circular hinge holes are provided at both ends of the short rod 112. One end of the circular hinge hole is connected to the shaft sleeve 111, and the other end is connected to the eccentric end rod 113; the short rod 112 drives the eccentric end rod 113 to rotate around the center of the blade unit. Attention should be paid when the circular hinge hole at one end of the short rod 112 is assembled with the reserved hinge slot on the shaft sleeve 111. Its structural characteristics do not interfere with the movement of the short rod 112 and the eccentric end rods 113 of other blade units. Inside the limited space of the housing 121, the thickness and length of the short rod 112 should also adapt to the stroke during movement to ensure that the blade deflects smoothly and steadily during movement. Here, it is required not to be too long.

[0052] In order to ensure that the entire air outlet system 100 completes the blowing action of basic blade rotation, the air outlet system 100 further includes a rotating mechanism 120; the rotating mechanism includes a housing 121 and a second motor 122, and the blade unit is connected to the housing 121; the second motor 122 drives the housing 121 to rotate. Among them, the second motor 122 can also be equipped with a temperature sensing control element according to actual needs, and the motor speed can be adjusted according to the temperature, further affecting the accuracy of the adjustment system. One end of the housing 121 is connected to the coupling by screws, and the other end is connected to the rotating shaft of the second motor 122. The second motor 122 provides torque for the rotation of the housing 121.

[0053] In an alternative embodiment of the present example, preferably, the blade unit includes a blade base 116 and a blade 117; a plurality of circular through-holes are provided on the housing 121; the blade base 116 is disposed within the circular through-hole, and the blade 117 is disposed outside the housing 121. The structural feature of the blade unit is that a frustum-shaped blade base 116 fitted on the circular hole of the housing 121 and an eccentric rod extending towards the lower end of the frustum, combined with a thin sheet fan blade above the frustum, and the independent blade units do not interfere with each other.

[0054] In order to better achieve the refrigeration cycle and air convection, the device further includes a refrigeration cycle system 200, which includes a refrigerant pipeline 210, a compressor 220, and a turbine motor 230. A charging pile housing is also provided, and the chassis assembly 300 is snap-fitted to the charging pile housing; there are chassis heat dissipation openings 320 on both sides and the bottom of the chassis assembly 300. It further includes an exhaust system 400, which includes an exhaust fan 410 and an exhaust opening 420; an exhaust fan 410 is provided on one side of the charging pile housing, and an exhaust opening 420 is provided on the other side. Among them, turbine blades are provided inside the turbine motor 230, and the turbine motor 230 can accelerate its own rotation according to the signal of the temperature sensor when the temperature changes, so as to improve the working efficiency of the water cooling system; the exhaust fan 410 and the exhaust opening 420 of the exhaust system 400 are on the same horizontal plane as the chassis heat dissipation openings 320 provided on both sides of the chassis assembly 300, and are connected in series to form a heat dissipation path, and air forms convection with the inside of the charging pile through this heat dissipation path to accelerate the internal heat dissipation and heat exchange.

[0055] Under the combined operation of the refrigeration cycle system 200, the exhaust system 400, and the air outlet system 100, the temperature sensor of the charging pile chassis assembly 300 transmits signals to each system, and each system adjusts its own operating power with the assistance of the temperature sensor as the temperature changes. The refrigeration cycle system 200 adjusts the refrigeration effect of the refrigerant pipeline 210 through the turbine motor 230; the air outlet system 100 affects the air outlet efficiency by adjusting the blade deflection angle; the exhaust system 400 and the chassis heat dissipation openings 320 of the chassis assembly 300 form a heat dissipation path, and each system enables the charging pile to achieve adaptive temperature regulation as a whole.

[0056] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: it is still possible to modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
