Description

Technical Field

[0001] This utility model relates to the field of charging gun technology, specifically to an adaptive temperature control protection structure for electronic components of charging piles. Background Technology

[0002] When charging at high power, the charging gun generates a lot of heat inside. Prolonged high-power charging can cause the high temperature to accumulate and be difficult to dissipate in time, which can damage the internal components of the charging gun. To protect the charging gun, a charging gun with heat dissipation function is designed.

[0003] For example, Chinese patent CN214267374U describes a charging gun with a heat dissipation device. The charging gun body has a handle fixedly connected to one side. Thermally conductive cooling units are provided on both the front and rear sides of the charging gun body. Each thermally conductive cooling unit includes a thermally conductive copper sheet and a cooling fan. Placement slots are provided on both the front and rear sides of the charging gun body. The inner surface of the placement slot is bonded to the outer surface of the thermally conductive copper sheet using an adhesive. This utility model relates to the field of charging gun cooling technology. This charging gun with a heat dissipation device, by incorporating the thermally conductive cooling units, uses the thermally conductive copper sheet to collect the internal heat and the cooling fan to dissipate the heat. Combined with the placement slots and the charging gun body, this achieves the effect of cooling the charging gun casing and accelerating the dissipation of internal heat. This not only greatly protects charging safety but also avoids the problem of burns caused by personnel handling the charging gun.

[0004] However, the above-mentioned structure uses a thermally conductive copper sheet to absorb heat from the contact area for heat dissipation, resulting in a significant decrease in the temperature at the contact point of the thermally conductive copper sheet, which is not conducive to overall cooling.

[0005] Based on this, the present invention designs an adaptive temperature control protection structure for the electronic components of charging piles to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, this utility model provides an adaptive temperature control protection structure for electronic components of charging piles.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

All components are installed inside the charging gun. The two ends of the resistor are fixedly connected to the base and emitter of the transistor, respectively. The positive terminal of the capacitor is connected to the collector of the transistor. The two ends of the temperature sensor are connected to the emitter of the transistor and the negative terminal of the capacitor, respectively. The positive and negative terminals of the motor are connected to the positive and negative terminals of the capacitor. The negative terminal of the capacitor is connected to the negative terminal of the power supply. The base of the transistor is connected to the positive terminal of the power supply. The motor is connected to the air drive assembly. The air outlet of the air drive assembly is oriented towards the electronic components of the charging pile.

[0010] The charging gun is equipped with a flow guiding component for guiding the flow of air.

[0011] The charging gun has an air intake component for air intake and an air outlet component for air exhaust at both ends of the temperature control component. The air intake component is located at the air intake end of the air drive component, and the air outlet component is located at the air outlet end of the air drive component. When the air is not flowing, the air outlet component and the air intake component are in the closed state. When the air is flowing, the air intake component automatically applies negative pressure, and the air outlet component automatically opens.

[0012] Furthermore, the air drive assembly includes an outer gear ring, fan blades, an inner gear ring, and a rotating cylinder. The rotating cylinder is rotatably connected to the inner wall of the charging gun via a bearing. An outer gear ring is fixedly connected to the inner wall of one end of the rotating cylinder, and the outer gear ring meshes with the inner gear ring. The inner gear ring is fixedly connected to the drive end of the motor. Fan blades are fixedly connected to the inner wall of the other end of the rotating cylinder at equal intervals along the circumference.

[0013] Furthermore, the flow guiding component includes a first annular inclined plate and a second annular inclined plate. The larger diameter portion of the first annular inclined plate and the larger diameter portion of the second annular inclined plate are fixedly connected to the charging gun. The smaller diameter portion of the first annular inclined plate is connected to the smaller diameter portion of the second annular inclined plate. The larger diameter portion of the first annular inclined plate is located near the inner gear ring.

[0014] Furthermore, the air outlet assembly includes a first straight hole, a first baffle, a first horizontal shaft, a first torsion spring, and a second straight hole. The charging gun has a second straight hole located below the end of the electronic component away from the air inlet assembly. The charging gun has a first straight hole located below the second straight hole. The size of the first straight hole is larger than that of the second straight hole. The first horizontal shaft is fixedly connected to the side wall of the first straight hole. The first baffle is rotatably connected to the first horizontal shaft. The first torsion spring is sleeved on the outer wall of the first horizontal shaft, and the two ends of the first torsion spring contact the first baffle and the inner wall of the first straight hole, respectively.

[0015] Furthermore, the first torsion spring always has an upward restoring force, and the magnitude of the restoring force is the same as the magnitude of the weight of the first baffle.

[0016] Furthermore, the air intake assembly includes a third straight hole, a second baffle, a fourth straight hole, a second horizontal shaft, and a second torsion spring. The charging gun has a fourth straight hole located below the air intake end of the temperature control assembly. The charging gun has a third straight hole located below the fourth straight hole.

[0017] Furthermore, the second torsion spring always has an upward restoring force, and the magnitude of the restoring force is the same as the magnitude of the weight of the second baffle.

[0018] Beneficial effects

[0019] During charging, the temperature sensor of the temperature control component detects the temperature. When the temperature rises, the power supply enters the motor through a resistor, transistor, and capacitor, starting the motor. The motor drives the air drive component to rotate, causing airflow inside the charging gun. The airflow guide component directs the airflow to the outside of the electronic components, providing air cooling for them. A negative pressure is created in the chamber of the air intake component, causing the air intake component to open automatically and allowing air to enter the charging gun. Simultaneously, a positive pressure is created in the chamber of the air outlet component, causing the air outlet component to open automatically, achieving overall adaptive temperature control protection. When protection is not in effect, both the air outlet and air intake components are closed, reducing the possibility of dust and moisture entering the charging gun. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] The present invention will be further described below with reference to the embodiments.

[0033] Example 1

[0034] Please refer to the instruction manual appendix. Figure 1-8 The charging pile electronic components adaptive temperature control protection structure includes temperature control component 4;

[0035] The temperature control component 4 includes an air drive component, a motor 43, a capacitor 46, a temperature sensor 47, a resistor 48, and a transistor 49. The air drive component, motor 43, capacitor 46, temperature sensor 47, resistor 48, and transistor 49 are all installed inside the charging gun 1. The two ends of the resistor 48 are fixedly connected to the base and emitter of the transistor 49, respectively. The positive terminal of the capacitor 46 is connected to the collector of the transistor 49. The two ends of the temperature sensor 47 are connected to the emitter of the transistor 49 and the negative terminal of the capacitor 46, respectively. The positive and negative terminals of the motor 43 are connected to the positive and negative terminals of the capacitor 46. The negative terminal of the capacitor 46 is connected to the negative terminal of the power supply. The base of the transistor 49 is connected to the positive terminal of the power supply. The motor 43 is connected to the air drive component. The air outlet of the air drive component is set towards the electronic components of the charging pile.

[0036] The charging gun 1 is equipped with a flow guiding component 5 for guiding the flow of air.

[0037] The power supply is a 12V power supply shared by the charging station;

[0038] The charging gun 1 has an air intake component 3 for air intake and an air outlet component 2 for air outlet at both ends of the temperature control component 4. The air intake component 3 is located at the air intake end of the air drive component, and the air outlet component 2 is located at the air outlet end of the air drive component of the air intake component 3. When the air is not flowing, the air outlet component 2 and the air intake component 3 are in a closed state. When the air flows, the air intake component 3 automatically applies negative pressure, and the air outlet component 2 automatically opens.

[0039] During charging, the temperature sensor 47 of the temperature control component 4 detects the temperature of the charging gun 1. After the temperature rises, the power supply enters the motor 43 through the resistor 48, transistor 49, and capacitor 46. The motor 43 starts and drives the air drive component to rotate. The rotating air drive component rotates the air flow in the charging gun 1. The air guide component 5 guides the air flow to the outside of the electronic components. The air flow cools the electronic components of the charging gun 1. A negative pressure is formed in the chamber of the air intake component 3 where the charging gun 1 is located. The air intake component 3 opens automatically and air enters the charging gun 1 through the air intake component 3. At the same time, a positive pressure is formed in the chamber of the air outlet component 2 where the charging gun 1 is located. The air outlet component 2 opens automatically, realizing overall adaptive temperature control protection. At the same time, when protection is not possible, the air outlet component 2 and the air intake component 3 are in the closed state to reduce the possibility of dust and moisture entering the charging gun 1.

[0040] The air drive assembly includes an outer gear ring 41, a fan blade 42, an inner gear ring 44, and a rotating cylinder 45. The rotating cylinder 45 is rotatably connected to the inner wall of the charging gun 1 via a bearing. An outer gear ring 41 is fixedly connected to the inner wall of one end of the rotating cylinder 45. The outer gear ring 41 is meshed with the inner gear ring 44, and the inner gear ring 44 is fixedly connected to the drive end of the motor 43. The fan blade 42 is fixedly connected to the inner wall of the other end of the rotating cylinder 45 at equal intervals along the circumference.

[0041] After the motor 43 is powered on, the motor 43 drives the internal gear ring 44 to rotate, the internal gear ring 44 drives the external gear ring 41 to rotate, the external gear ring 41 drives the rotating cylinder 45 to rotate, the rotating cylinder 45 drives the fan blade 42 to rotate, and the fan blade 42 drives the air to flow.

[0042] The flow guiding component 5 includes a first annular inclined plate 51 and a second annular inclined plate 52. The larger diameter portion of the first annular inclined plate 51 and the larger diameter portion of the second annular inclined plate 52 are fixedly connected to the charging gun 1. The smaller diameter portion of the first annular inclined plate 51 and the smaller diameter portion of the second annular inclined plate 52 are connected. The larger diameter portion of the first annular inclined plate 51 is located near the internal gear ring 44.

[0043] When the air driven by the fan blade 42 flows, the first annular inclined plate 51 guides the flowing air and sprays it towards the end of the electronic component near the temperature control component 4 to cool the end of the electronic component. The end of the electronic component is refracted onto the second annular inclined plate 52, and then the second annular inclined plate 52 refracts and moves to the inner wall of the charging gun 1, where it flows and cools the outer wall of the electronic component.

[0044] The air outlet assembly 2 includes a first straight hole 21, a first baffle 22, a first horizontal shaft 23, a first torsion spring 24, and a second straight hole 25. The charging gun 1 is located below the end of the electronic component away from the air inlet assembly 3 and has the second straight hole 25. The charging gun 1 has the first straight hole 21 below the second straight hole 25. The size of the first straight hole 21 is larger than the size of the second straight hole 25. The first horizontal shaft 23 is fixedly connected to the side wall of the first straight hole 21. The first baffle 22 is rotatably connected to the first horizontal shaft 23. The first torsion spring 24 is sleeved on the outer wall of the first horizontal shaft 23, and the two ends of the first torsion spring 24 are in contact with the first baffle 22 and the inner wall of the first straight hole 21, respectively.

[0045] The first torsion spring 24 always has an upward torsional restoring force, and the magnitude of the restoring force is the same as the magnitude of the weight of the first baffle 22;

[0046] Air flows toward the end of the electronic component away from the air intake assembly 3, and the air pressure at the end of the electronic component away from the air intake assembly 3 increases. The air pressure pushes the first baffle 22 downward and flips along the first horizontal axis 23. Air flows out from the second straight hole 25 and the gap between the first straight hole 21 and the first baffle 22.

[0047] When not air-cooled, the restoring force of the first torsion spring 24 causes the first baffle 22 to rotate upward until it contacts the top of the first straight hole 21, thus sealing the bottom of the second straight hole 25 and reducing the possibility of dust and moisture entering the charging gun 1.

[0048] The air intake assembly 3 includes a third straight hole 31, a second baffle 32, a fourth straight hole 33, a second horizontal shaft 34, and a second torsion spring 35. The charging gun 1 is located below the air intake end of the temperature control assembly 4 and has a fourth straight hole 33. The charging gun 1 has a third straight hole 31 below the fourth straight hole 33. The size of the third straight hole 31 is larger than the size of the fourth straight hole 33. The second horizontal shaft 34 is fixedly connected to the side wall of the fourth straight hole 33. The second baffle 32 is rotatably connected to the second horizontal shaft 34. The second torsion spring 35 is sleeved on the outer wall of the second horizontal shaft 34, and the two ends of the second torsion spring 35 are respectively in contact with the inner walls of the fourth straight hole 33 and the second baffle 32.

[0049] The second torsion spring 35 always has an upward restoring force, and the magnitude of the restoring force is the same as the magnitude of the weight of the second baffle 32;

[0050] Air flows toward the end of the electronic components away from the air intake assembly 3. The air pressure at the air intake end of the temperature control assembly 4 decreases, forming a negative pressure. The negative pressure causes the second baffle 32 to flip downward along the second horizontal axis 34. Air flows out from the gap between the third straight hole 31, the fourth straight hole 33, and the second baffle 32 and enters the charging gun 1.

[0051] When not air-cooled, the restoring force of the second torsion spring 35 causes the second baffle 32 to rotate upward until it contacts the top of the second horizontal shaft 34, sealing the top of the third straight hole 31 and reducing the possibility of dust and moisture entering the charging gun 1.

[0052] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
