Description

Technical Field

[0001] The invention belongs to the field of extremely cold charging piles. Background Art

[0002] In high-cold areas, the ambient temperature is extremely low. Traditional charging piles may face problems such as reduced charging efficiency, affected battery performance, and possible failure of the equipment itself in low temperature environments. Extremely low temperature environments may cause damage to the electronic components and mechanical parts inside the charging piles, such as causing various components on the circuit board to crack, relay action parts to be inflexible, performance degradation and other risks; the heating materials used in existing charging piles have certain limitations, such as uneven heating, high energy consumption, or the inability to effectively maintain a suitable working temperature at extremely low temperatures. The use of fans combined with heating wires will also accelerate the heat exchange between the relatively high temperature gas in the cabinet and the inner wall of the chassis shell, resulting in a high heat loss rate. Summary of the invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a temperature control system for flexible carbon fiber micro-electric heating materials in charging piles in cold regions, which reduces heat loss and improves the uniformity and pertinence of heating.

[0004] Technical solution: To achieve the above-mentioned purpose, the temperature control system of the flexible carbon fiber micro-electric heating material in the high-cold area charging pile of the present invention includes an electrical cabinet for the high-cold area charging pile, which includes at least an upper cabinet cavity and a lower cabinet cavity, and both the upper cabinet cavity and the lower cabinet cavity are provided with a roller-curtain type carbon fiber micro-electric heater, which includes a rolled-up state and an unfolded state.

[0005] Furthermore, the rolling-curtain type carbon fiber micro-electric heater is installed at the upper end of the upper cabinet cavity or the lower cabinet cavity; the rolling-curtain type carbon fiber micro-electric heater is hung in the center of the upper cabinet cavity or the lower cabinet cavity in the unfolded state.

[0006] Furthermore, the roller-type carbon fiber micro-electric heater includes a roller-type roller blind shaft and a heat-equalizing roller blind cloth. The heat-equalizing roller blind cloth is a heat-resistant fiber cloth structure made of insulating material. The roller-type roller blind shaft is horizontally arranged. The upper edge of the heat-equalizing roller blind cloth in the unfolded state is fixedly connected to the roller blind shaft along the length direction, and the lower edge of the heat-equalizing roller blind cloth in the unfolded state is fixedly connected to the transverse counterweight bar along the length direction.

[0007] Furthermore, two metal rings are fixedly mounted on the roller blind shaft made of insulating material, and the two metal rings are respectively a first metal ring and a second metal ring; conductive carbon fiber heating ribbons are evenly sewn in a zigzag and evenly distributed manner inside the fabric body of the heat-isolating roller blind fabric, and the head and tail ends of the conductive carbon fiber heating ribbons are respectively electrically connected to the first metal ring and the second metal ring.

[0008] Furthermore, a mounting beam is arranged parallel to the upper side of the rolling shutter shaft, and the mounting beam is fixedly installed on the upper end of the upper cabinet cavity or the lower cabinet cavity. Two bearing seats are arranged on the lower sides of both ends of the mounting beam, and the two ends of the rolling shutter shaft are rotatably installed on the bearing seats through bearings. A roller drive motor is fixedly installed on one end of the mounting beam, and the roller drive motor is drive-connected to the rolling shutter shaft.

[0009] Furthermore, two electrical connection boxes made of bonding material with openings facing downward are fixedly provided on the lower side of the mounting beam, and the two electrical connection boxes are respectively a first electrical connection box and a second electrical connection box; the first electrical connection box and the second electrical connection box are respectively directly above the first metal ring and the second metal ring; each electrical connection box has a curled electrode sheet fixedly installed in it through an electrode holder; the electrode sheets in the first electrical connection box and the second electrical connection box are respectively electrically connected to the positive and negative poles of the DC power supply.

[0010] Furthermore, a metal swing shaft is provided between each electrical box and the metal ring directly below, the axis of the metal swing shaft is parallel to the roller blind axis, one end of the metal swing shaft is coaxially connected to a rotating shaft, the end of the rotating shaft is rotatably mounted on a rotating shaft bracket through a bearing, and the upper section of the rotating shaft bracket is fixedly connected to the electrical box;

[0011] The lower side of the metal swing shaft is integrally connected with an arc-shaped brush sheet extending obliquely downward, with the convex surface of the arc-shaped brush sheet facing downward, and the upper side of the metal swing shaft is integrally connected with an arc-shaped conductive spring sheet extending obliquely upward, with the convex surface of the arc-shaped conductive spring sheet facing upward;

[0012] A torsion plate is coaxially arranged at the connection between the rotating shaft and the metal swing shaft, and a torsion spring is arranged outside the rotating shaft, and the torsion spring applies a clockwise torque to the torsion plate;

[0013] When the heat-averaging rolling curtain cloth is fully unfolded and hanging, the torsion spring applies a clockwise torque to the metal swing shaft, so that the convex surface of the upper end of the arc-shaped conductive spring sheet swings upward into the power connection box, and the convex surface of the upper end of the arc-shaped conductive spring sheet electrically contacts the electrode sheet in the power connection box. A part of the torsion force applied by the torsion spring to the torsion disk is converted into a top pressure between the convex surface of the upper end of the arc-shaped conductive spring sheet and the electrode sheet in the power connection box, so that the arc-shaped conductive spring sheet undergoes adaptive elastic deformation at this time; at the same time, another part of the torsion force applied by the torsion spring to the torsion disk is converted into a top pressure between the convex surface of the arc-shaped brush sheet and the outer peripheral surface of the metal ring, so that the convex surface of the arc-shaped brush sheet is closely tangent to the outer peripheral surface of the metal ring and is electrically connected.

[0014] Furthermore, on the basis of the heat-equalizing rolling curtain cloth being fully unfolded and hanging, the active rotation of the rolling curtain shaft causes the heat-equalizing rolling curtain cloth to be gradually wound on the rolling curtain shaft, forming a rolled cloth wound outside the rolling curtain shaft, and the newly formed rolled cloth isolates the metal ring from the arc-shaped brush sheet, so that the convex arc surface of the arc-shaped brush sheet is tangent to the outermost layer of the rolled cloth. As the rolled cloth is further wound, the outer diameter of the outermost layer of the rolled cloth gradually increases, and gradually pushes the arc-shaped brush sheet tangent to it, so that the metal swing shaft overcomes the torsion of the torsion spring and gradually rotates counterclockwise, thereby driving the originally elastically deformed arc-shaped conductive spring sheet to gradually recover to a free state and continue to swing downward, so that the arc-shaped conductive spring sheet is separated from the electrode sheet.

[0015] Beneficial effect: The roller curtain type carbon fiber micro-electric heater of the present invention is hung in the center of the upper cabinet cavity or the lower cabinet cavity in the unfolded state; thereby further dividing the space in the upper cabinet cavity or the lower cabinet cavity is achieved, reducing the air flow in the upper cabinet cavity or the lower cabinet cavity, and further reducing the heat exchange between the air in the upper cabinet cavity or the lower cabinet cavity and the inner wall of the cabinet of the charging pile electrical cabinet in the high-cold area; at the same time, the heat-equalizing roller curtain cloth in the heating state hanging in the center of the upper cabinet cavity or the lower cabinet cavity is uniformly heated by heat conduction to the air in the upper cabinet cavity or the lower cabinet cavity, so that the temperature in the upper cabinet cavity or the lower cabinet cavity is uniformly increased and reaches a dynamic balance. At the same time, the two sides of the heat-equalizing roller curtain cloth in the heating state radiate heat to the electrical components distributed on both sides of the heat-equalizing roller curtain cloth in the form of thermal radiation, so that the electrical components on both sides of the heat-equalizing roller curtain cloth maintain a stable temperature under the action of thermal radiation, and avoid damage due to extremely cold temperatures;

[0016] During the upward winding process of the hot rolling curtain cloth, at the initial stage of winding, the newly formed rolling cloth will isolate the metal ring and the arc-shaped brush piece in advance, so that the conductive carbon fiber heating ribbon in the heat-averaging rolling curtain cloth will be powered off in advance, structurally avoiding the risk of overheating and fire caused by power being supplied while still in the wound state. At the same time, the convex arc surface of the arc-shaped brush piece is tangent to the outermost layer of the newly wound rolling cloth. As the rolling cloth is further wound, the outer diameter of the outermost layer of the rolling cloth gradually increases, gradually pushing the arc-shaped brush piece tangent to it, so that the metal swing shaft overcomes the torsion of the torsion spring and gradually rotates counterclockwise, thereby driving the originally elastically deformed arc-shaped conductive spring piece to gradually recover to a free state and continue to swing downward, so that the arc-shaped conductive spring piece is separated from the electrode piece, thereby physically disconnecting the exposed arc-shaped brush piece from the arc-shaped brush piece hidden in the electrical box, avoiding the risk of electric shock caused by touching the exposed arc-shaped brush piece during the maintenance stage.

[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] As attached Figures 1 to 9 The temperature control system of the flexible carbon fiber micro-electric heating material in the high-cold area charging pile shown in the figure includes an electrical cabinet 1 of the high-cold area charging pile, such as Figure 1 The high-cold region charging pile electrical cabinet 1 includes at least an upper cabinet cavity 2 and a lower cabinet cavity 3, and a rolling curtain type carbon fiber micro-electric heater 6 is arranged in both the upper cabinet cavity 2 and the lower cabinet cavity 3. The rolling curtain type carbon fiber micro-electric heater 6 includes a rolled-up state and an unfolded state. The rolling curtain type carbon fiber micro-electric heater 6 is installed at the upper end of the upper cabinet cavity 2 or the lower cabinet cavity 3; Figure 2 The roller-curtain-type carbon fiber micro-electric heater 6 is hung in the center of the upper cabinet cavity 2 or the lower cabinet cavity 3 in the unfolded state; thereby further dividing the space in the upper cabinet cavity 2 or the lower cabinet cavity 3 is achieved, reducing the air flow in the upper cabinet cavity 2 or the lower cabinet cavity 3, and thereby reducing the heat exchange between the air in the upper cabinet cavity 2 or the lower cabinet cavity 3 and the inner wall of the cabinet of the high-cold area charging pile electrical cabinet 1; at the same time, the heat-equalizing roller curtain 4 in the heating state hanging in the center of the upper cabinet cavity 2 or the lower cabinet cavity 3 uniformly heats the air in the upper cabinet cavity 2 or the lower cabinet cavity 3 through heat conduction, so that the temperature in the upper cabinet cavity 2 or the lower cabinet cavity 3 is uniformly increased and reaches a dynamic balance. At the same time, the two sides of the heat-equalizing roller curtain 4 in the heating state radiate heat to the electrical components distributed on both sides of the heat-equalizing roller curtain 4 in the form of thermal radiation, so that the electrical components on both sides of the heat-equalizing roller curtain 4 maintain a stable temperature under the action of thermal radiation, avoiding damage due to extremely cold temperatures.

[0028] The roller-curtain type carbon fiber micro-electric heater 6 includes a roller-curtain shaft 11 and a heat-equalizing roller-curtain cloth 4. The heat-equalizing roller-curtain cloth 4 is a heat-resistant fiber cloth structure made of insulating material. The roller-curtain shaft 11 is horizontally arranged. The upper edge of the heat-equalizing roller-curtain cloth 4 in the unfolded state is fixedly connected to the roller-curtain shaft 11 along the length direction, and the lower edge of the heat-equalizing roller-curtain cloth 4 in the unfolded state is fixedly connected to the transverse counterweight bar 9 along the length direction.

[0029] Two metal rings 13 are fixedly sleeved on the roller blind shaft 11 of insulating material, and the two metal rings 13 are respectively the first metal ring 13a and the second metal ring 13b; the conductive carbon fiber heating ribbon 5 is evenly sewn in a zigzag and evenly distributed manner in the cloth body of the heat-averaging roller blind cloth 4, and the ends of the conductive carbon fiber heating ribbon 5 are electrically connected to the first metal ring 13a and the second metal ring 13b respectively; the conductive carbon fiber heating ribbon 5 uses polyacrylonitrile (PAN)-based carbon fiber with high strength and good conductivity, and the use of thinner carbon fiber tows has more advantages in flexibility and heating uniformity. The carbon fiber is combined with the matrix through composite processes such as lamination and winding to ensure the continuity of the carbon fiber and the integrity of the conductive path. It can quickly generate heat when powered on, and has high heating efficiency, and can raise the internal temperature of the charging pile to a suitable working range in a short time. The carbon fiber material itself has good flexibility and strength, can adapt to the complex installation environment inside the charging pile, and is not easy to be damaged.

[0030] like Figure 3 and 4 A mounting beam 7 is arranged parallel to the upper side of the rolling curtain shaft 11, and the mounting beam 7 is fixedly installed on the upper end of the upper cabinet cavity 2 or the lower cabinet cavity 3. Two bearing seats 10 are arranged on the lower sides of both ends of the mounting beam 7. Both ends of the rolling curtain shaft 11 are rotatably mounted on the bearing seats 10 through bearings. A reel drive motor 8 is fixedly installed on one end of the mounting beam 7, and the reel drive motor 8 is drivingly connected to the rolling curtain shaft 11.

[0031] Two junction boxes 12 with openings facing downward are fixedly arranged on the lower side of the mounting beam 7. The two junction boxes 12 are respectively a first junction box 12a and a second junction box 12b. The first junction box 12a and the second junction box 12b are respectively located directly above the first metal ring 13a and the second metal ring 13b. Figure 7 A curled electrode sheet 21 is fixedly mounted in each electrical connection box 12 through an electrode holder 20; the electrode sheets 21 in the first electrical connection box 12a and the second electrical connection box 12b are electrically connected to the positive and negative electrodes of the DC power supply respectively.

[0032] like Figure 6 and 7A metal swing shaft 24 is arranged between each electrical box 12 and the metal ring 13 directly below. The axis of the metal swing shaft 24 is parallel to the roller blind shaft 11. One end of the metal swing shaft 24 is connected to a rotating shaft 27 coaxially. The end of the rotating shaft 27 is rotatably mounted on a rotating shaft bracket 28 through a bearing. The upper section of the rotating shaft bracket 28 is fixedly connected to the electrical box 12; the lower side of the metal swing shaft 24 is connected to an arc-shaped brush piece 23 extending obliquely downward, with the convex surface of the arc-shaped brush piece 23 facing downward, and the upper side of the metal swing shaft 24 is connected to an arc-shaped conductive spring piece 22 extending obliquely upward, with the convex surface of the arc-shaped conductive spring piece 22 facing upward; a torsion plate 25 is coaxially arranged at the connection between the rotating shaft 27 and the metal swing shaft 24, and a torsion spring 26 is arranged outside the rotating shaft 27. The torsion spring 26 applies a clockwise torque to the torsion plate 25; in the heat balancing When the rolling curtain 4 is fully unfolded and hanging, the torsion spring 26 applies a clockwise torque to the metal swing shaft 24, so that the upper convex surface of the arc-shaped conductive spring piece 22 swings upward into the power connection box 12, and the upper convex surface of the arc-shaped conductive spring piece 22 electrically contacts the electrode piece 21 in the power connection box 12. A part of the torsion force applied by the torsion spring 26 to the torsion plate 25 is converted into a pressing force between the upper convex surface of the arc-shaped conductive spring piece 22 and the electrode piece 21 in the power connection box 12, so that the arc-shaped conductive spring piece 22 undergoes adaptive elastic deformation at this time; at the same time, another part of the torsion force applied by the torsion spring 26 to the torsion plate 25 is converted into a pressing force between the convex surface of the arc-shaped brush piece 23 and the outer peripheral surface of the metal ring 13, so that the convex surface of the arc-shaped brush piece 23 is closely tangent to the outer peripheral surface of the metal ring 13 and is electrically connected.

[0033] On the basis that the heat-distributing rolling curtain 4 is in a fully unfolded and hanging state, the active rotation of the rolling curtain shaft 11 causes the heat-distributing rolling curtain 4 to be gradually wound around the rolling curtain shaft 11, such as Figure 8 and 9 , forming a roll cloth 4a wound outside the rolling blind shaft 11, the newly formed roll cloth 4a isolates the metal ring 13 from the arc-shaped brush piece 23, so that the convex arc surface of the arc-shaped brush piece 23 is tangent to the outermost layer of the roll cloth 4a. As the roll cloth 4a is further wound, the outer diameter of the outermost layer of the roll cloth 4a gradually increases, and gradually pushes the arc-shaped brush piece 23 tangent thereto, so that the metal swing shaft 24 overcomes the torsion of the torsion spring 26 and gradually rotates counterclockwise, thereby driving the originally elastically deformed arc-shaped conductive spring piece 22 to gradually recover to a free state and continue to swing downward, so that the arc-shaped conductive spring piece 22 is separated from the electrode piece 21.

[0034] Working method and working principle: When the charging pile is working in an extremely cold ambient temperature, the rolling curtain type carbon fiber micro-electric heater 6 in the upper cabinet cavity 2 and the lower cabinet cavity 3 are both in an unfolded state;

[0035] In the unfolded state, the heat-distributing rolling curtain fabric 4 of the rolling curtain type carbon fiber micro-electric heater 6 is hung in the center of the upper cabinet cavity 2 or the lower cabinet cavity 3 in the unfolded state; at this time, each torsion spring 26 applies a clockwise torque to the corresponding metal swing shaft 24, so that the upper convex surface of the arc-shaped conductive spring sheet 22 swings upward to the power connection box 12, and the upper convex surface of the arc-shaped conductive spring sheet 22 electrically contacts the electrode sheet 21 in the power connection box 12, and a part of the torsion force applied by the torsion spring 26 to the torsion plate 25 is converted into the arc-shaped conductive spring sheet 2 2 and the electrode sheet 21 in the electrical connection box 12, so that the arc-shaped conductive spring sheet 22 undergoes adaptive elastic deformation; at the same time, another part of the torsion force applied by the torsion spring 26 to the torsion plate 25 is converted into a top pressure between the convex surface of the arc-shaped brush sheet 23 and the outer peripheral surface of the metal ring 13, so that the convex surface of the arc-shaped brush sheet 23 and the outer peripheral surface of the metal ring 13 are closely tangent and electrically connected; so that the conductive carbon fiber heating ribbon 5 in the heat-averaging rolling curtain fabric 4 is connected to the positive and negative terminals of the power supply. The heat released by the conductive carbon fiber heating ribbon 5 is transferred to the unfolded heat-distributing roller curtain 4 to heat up the heat-distributing roller curtain 4 as a whole. Since the heat-distributing roller curtain 4 in the heated state is hung in the center of the upper cabinet cavity 2 or the lower cabinet cavity 3, the space in the upper cabinet cavity 2 or the lower cabinet cavity 3 is further divided, and the air flow in the upper cabinet cavity 2 or the lower cabinet cavity 3 is reduced, thereby reducing the heat exchange between the air in the upper cabinet cavity 2 or the lower cabinet cavity 3 and the inner wall of the cabinet of the high-cold area charging pile electrical cabinet 1; at the same time, the heat-distributing roller curtain 4 in the heated state hanging in the center of the upper cabinet cavity 2 or the lower cabinet cavity 3 is uniformly heated by heat conduction to the air in the upper cabinet cavity 2 or the lower cabinet cavity 3, so that the temperature in the upper cabinet cavity 2 or the lower cabinet cavity 3 is uniformly increased and reaches a dynamic balance. At the same time, the two sides of the heat-distributing roller curtain 4 in the heated state radiate heat to the electrical components distributed on both sides of the heat-distributing roller curtain 4 in the form of thermal radiation, so that the electrical components on both sides of the heat-distributing roller curtain 4 maintain a stable temperature under the action of thermal radiation, avoiding damage due to extremely cold temperatures;

[0036] Although the heat-distributing rolling curtain 4 in the unfolded state has the above-mentioned advantages, since the heat-distributing rolling curtain 4 is hung in the center of the upper cabinet cavity 2 or the lower cabinet cavity 3 in the unfolded state, it blocks the sight of the maintenance and repair personnel, etc., which will seriously affect and interfere with the unpacking maintenance and repair of the high-cold area charging pile electrical cabinet 1 by the staff. At the same time, the metal ring 13 at the upper end of the heat-distributing rolling curtain 4 in the unfolded state is in an exposed state, which poses a risk of electric shock; therefore, once the charging pile enters the maintenance state, the heat-distributing rolling curtain 4 needs to be safely rolled up; the specific rolling process is as follows:

[0037] The roller drive motor 8 drives the roller blind shaft 11 to actively rotate in the positive direction. The active rotation of the roller blind shaft 11 causes the heat-equalizing roller blind fabric 4 to be gradually wound around the roller blind shaft 11, forming a roll cloth 4a wound outside the roller blind shaft 11. In the initial stage of winding, the newly formed roll cloth 4a isolates the metal ring 13 and the arc-shaped brush sheet 23 in advance, so that the conductive carbon fiber heating ribbon 5 in the heat-equalizing roller blind fabric 4 is powered off in advance, thereby structurally avoiding the risk of overheating and fire caused by power being supplied while still in the wound state. At the same time, the convex arc surface of the arc-shaped brush sheet 23 is tangent to the outermost layer of the newly wound roll cloth 4a. As the roll cloth 4a is further wound, the outer diameter of the outermost layer of the roll cloth 4a gradually increases. , gradually pushes the arc-shaped brush piece 23 tangent to it, so that the metal swing shaft 24 overcomes the torsion of the torsion spring 26 and gradually rotates counterclockwise, thereby driving the originally elastically deformed arc-shaped conductive spring piece 22 to gradually recover the free state and continue to swing downward, so that the arc-shaped conductive spring piece 22 is separated from the electrode piece 21, so that the exposed arc-shaped brush piece 23 is physically disconnected from the arc-shaped brush piece 23 hidden in the electrical box 12, avoiding the risk of electric shock caused by touching the exposed arc-shaped brush piece 23 during the maintenance stage; with the continuous positive rotation of the rolling curtain shaft 11, until the heated rolling curtain cloth 4 in the unfolded state is transformed into the rolled cloth 4a in the wound state, the safe winding process is completed;

[0038] When the inspection is completed, the rolling cloth 4a needs to be changed back to the unfolded state and powered on. At this time, the roller blind shaft 11 is driven by the roller drive motor 8 to rotate in the opposite direction until the roller blind shaft 11 is completely exposed. The convex surface of the arc-shaped brush piece 23 is tightly tangent to the outer peripheral surface of the metal ring 13 again and is electrically connected, so that the unfolded heat-averaging rolling cloth 4 is heated again.

[0039] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.

The temperature control system of the flexible carbon fiber micro-electric heating material in the charging pile in the cold region according to claim 7, characterized in that: On the basis that the heat-equalizing rolling curtain cloth (4) is in a fully unfolded hanging state, the active rotation of the rolling curtain shaft (11) causes the heat-equalizing rolling curtain cloth (4) to be gradually wound around the rolling curtain shaft (11), forming a rolled cloth (4a) wound outside the rolling curtain shaft (11); the newly formed rolled cloth (4a) isolates the metal ring (13) from the arc-shaped brush sheet (23), so that the convex arc surface of the arc-shaped brush sheet (23) is tangent to the outermost layer of the rolled cloth (4a); as the rolled cloth (4a) is further wound, the outer diameter of the outermost layer of the rolled cloth (4a) gradually increases, thereby gradually pushing the arc-shaped brush sheet (23) tangent thereto, causing the metal swing shaft (24) to overcome the torsion of the torsion spring (26) and gradually rotate counterclockwise, thereby driving the originally elastically deformed arc-shaped conductive spring sheet (22) to gradually recover to a free state and continue to swing downward, so that the arc-shaped conductive spring sheet (22) is separated from the electrode sheet (21).
