Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and in particular to a charging pile with a modular structure and a silent heat dissipation system. Background Art

[0002] The function of a charging pile is similar to that of a gas pump in a gas station. It can be fixed on the ground or on a wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. It can charge various models of electric vehicles according to different voltage levels.

[0003] Most existing charging piles adopt an integrated design, with various accessories tightly integrated and wired together, which lacks flexibility. This makes the charging pile difficult to install and maintain. For example, when a component fails, the entire charging pile needs to be disassembled and repaired, which is not only time-consuming and labor-intensive, but may also affect the operation of other normal components.

[0004] In addition, in order to ensure normal operation, existing charging piles need to dissipate heat from internal electronic components. Traditional heat dissipation methods usually use fans, which generate a lot of noise. In addition, transformers and inductor components also generate certain electromagnetic noise, which will interfere with the surrounding environment.

[0005] Therefore, there is a need for a charging pile with a modular structure and a silent heat dissipation system, which can solve the problems of the existing charging pile structure being difficult to install and maintain and having high noise during operation. Summary of the invention

DETAILED DESCRIPTION

[0045] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Embodiment 1

[0046] like Figure 1-Figure 7As shown, the present embodiment discloses a charging pile with a modular structure and a silent heat dissipation system, comprising an equipment chassis 1, a front chassis door 2 is provided at the front end of the equipment chassis 1, a rear chassis door 3 is provided at the rear end of the equipment chassis 1, and air inlets 12 are provided at both left and right ends of the equipment chassis 1. When the charging pile is in a working state, outside air enters from the air inlet 12 to dissipate internal heat, and two mounting plates 13 arranged left and right are fixedly installed on the bottom wall of the inner cavity of the equipment chassis 1. The material of the two mounting plates 13 is sound insulation material (i.e., a type of material that can block sound propagation or reduce transmitted sound energy, such as gypsum board or sound-absorbing cotton attached to its surface, etc.), and a first bearing plate 14 located in the middle and a second bearing plate 15 located in the upper part are fixedly installed between the two mounting plates 13. The first bearing plate 14 and the second bearing plate 15 divide the interior of the equipment chassis 1 into three parts: upper, middle and lower. Two mounting rods 110 arranged front and back are commonly provided between the first bearing plate 14 and the second bearing plate 15.

[0047] Furthermore, a power control module 6 is provided at the bottom of the inner cavity of the equipment chassis 1. The power control module 6 is a prior art, and contains a circuit breaker and an AC contactor therein, which can connect and disconnect the circuit and control the power-on state of the entire charging pile. A charging module 5 is provided at the upper end of the first carrier plate 14. The charging module 5 is the core component of the charging pile, and can convert the input AC power into DC power to provide a suitable charging voltage and current for the battery of the electric vehicle. The charging module 5 is composed of two left-right symmetrical charging components, and the two charging components are respectively located on the left and right sides of the two mounting rods 110. Since different electric vehicle batteries have different requirements for charging current and voltage, a control module 4 is provided at the front of the upper end of the second carrier plate 15. The control module 4 can accurately control the current and voltage output by the charging module to meet the charging needs of different types of electric vehicle batteries, and the control module 4 needs to be connected to the cable of the charging gun of the charging pile. An insulating plate 11 is provided at the rear of the upper end of the second carrier plate 15.

[0048] Specifically, Figure 8-Figure 10 As shown, the charging assembly includes two partitions 51, and limit strips 52 are provided on the upper and lower sides of the ends of the two partitions 51 that are close to each other. A plurality of symmetrical bending strips 53 are provided in the middle of the ends of the two partitions 51 that are close to each other. A plurality of charging modules 54 are provided between the two partitions 51. The charging module 54 is a prior art and is an important component of the charging module 5. The purpose of the charging module 54 is to convert the alternating current in the power grid into direct current that can be used to charge the power battery of the new energy vehicle. In the process of rectification and transformation, part of the electrical energy will be converted into heat. The charging module 54 is the component with the most serious heat generation in the entire charging pile.

[0049] Furthermore, two cooling fans 55 are provided at the front ends of the multiple charging modules 54. When the charging modules 54 are working, they can drive the cooling fans 55 to work, draw air from the front side and pass through the inside of the charging modules 54 for heat dissipation, and then discharge the air from the rear side. The cooling fans 55 and multiple charging modules 54 are all provided at the upper ends of the corresponding two bending strips 53 or the limiting strips 52. Fig.10 It can be seen that the bending strip 53 is processed by adopting the process of sheet metal incision bending (that is, first making an incision on the sheet metal part, and then bending along the incision to form the sheet metal part into a structure with a certain angle and shape), and the limit strip 52 is processed by adopting the process of sheet metal bending (that is, using pressure to force the sheet metal part to produce plastic deformation, thereby forming a stamping process with a certain angle and curvature). Therefore, the bending strips 53 or the limit strips 52 on both sides are integrated with the partition 51, so that the two are not easily deformed due to their weight when supporting the cooling fan 55, and the incision generated when processing the bending strip 53 can ensure smooth air circulation while ensuring that the upper and lower sides of the cooling fan 55 are suspended in the air, thereby improving the heat dissipation effect. The front ends of the multiple charging modules 54 are fixedly connected with the hollow front baffle 56, and the rear ends of the two partitions 51 are commonly fixedly connected with the hollow rear baffle 58, which is convenient for air to enter and exit.

[0050] In addition, the two partitions 51 close to each other in the two charging components are fixedly connected to the two mounting rods 110, and the two partitions 51 far from each other in the two charging components are fixedly connected to the first cover plate 16 on the corresponding side. Therefore, when the installer installs the charging module 5, the four partitions 51 can be installed first, and the partitions 51 can be fixedly installed with the corresponding mounting rods 110 or the first cover plate 16 by bolts, and then the rear baffles 58 on both sides can be installed. At this time, the multiple front baffles 56 with the charging module 54 can be directly pushed into the corresponding position in turn, and the front baffles 56 and the limit strips 52 and the mounting rods 110 located on the front side can be fixedly connected by bolts. When the charging module 54 needs to be taken out for inspection, the corresponding charging module 54 can be pulled out by directly loosening the bolts at the front end of the front baffle 56. In addition, the front ends of the multiple front baffles 56 are fixedly connected with handles 57 to facilitate the removal and placement of the front baffles 56.

[0051] Since the conventional charging pile requires the installer to connect the wires in the equipment chassis 1 during installation, and the various accessories are tightly integrated together for wiring, the operation is inconvenient. In order to improve the convenience of the installation of the charging pile, Figure 11-Figure 17As shown, the control module 4 includes a rectangular frame 41, the upper end and the left and right ends of the rectangular frame 41 are hollowed out, the front end of the rectangular frame 41 is rotatably mounted with a flip cover 42, and the front end of the flip cover 42 is fixedly connected with a mainboard 45, which is a prior art. The mainboard 45 mainly plays the role of overall coordination and control, and can receive feedback information from various sensors and input signals, including power control unit 46. The mainboard 45 will make comprehensive judgments and decisions based on this information to ensure the safe and stable operation of the charging pile. The rear wall of the inner cavity of the rectangular frame 41 is provided with a plurality of power modules 43, which is a prior art. The power module 43 can convert different levels of input voltage into output voltage suitable for specific electronic equipment or systems, that is, convert the 220V AC power of the city power into 5V, 12V, 24V and other DC power for the operation of the equipment in the charging pile. A power control unit 46 is provided at the rear end of the rectangular frame 41. The power control unit 46 is connected to the charging gun. The power control unit 46 is a prior art. The power control unit 46 includes accessories such as a sensor group and a DC contactor. The main purpose of the power control unit 46 is to control the output power of the charging gun during operation. A support frame 44 is also provided on one side between the rectangular frame 41 and the flip cover 42. When the flip cover 42 is opened, the support frame 44 is used to support between the flip cover 42 and the rectangular frame 41. A connecting block 421 is fixedly connected to the rear end of the flip cover 42 corresponding to the position of the support frame 44.

[0052] It should be noted that, since the upper end and the left and right ends of the rectangular frame 41 are hollow, when installing the control module 4, the power module 43, the main board 45, and the power control unit 46 can be pre-connected outside the charging pile, and then the installed control module 4 is pushed into the device chassis 1 along the second bearing plate 15 as a whole, and then the gun wire of the charging gun is connected to the power control unit 46 from both sides (the installer installs from the back side of the device chassis 1), and finally the insulating plate 11 is installed. In this way, most of the accessories can be avoided from being wired in the device chassis 1, and the modular structure of first completing the wiring of the control module 4 can improve the work efficiency of the installer.

[0053] Further, such as Figure 16-Figure 18As shown, the support frame 44 includes a first connecting rod 441 and a second connecting rod 446, the first connecting rod 441 is rotatably connected to the connecting block 421, the second connecting rod 446 is rotatably connected to the rectangular frame 41, the end of the first connecting rod 441 away from the connecting block 421 is fixedly connected to the limiting plate 443, the end of the second connecting rod 446 away from the rectangular frame 41 is fixedly connected to the positioning pin 444, the outer surface of the first connecting rod 441 away from the connecting block 421 is also provided with a straight groove 442 running through the left and right, the positioning pin 444 is movably installed in the straight groove 442, and the outer surface of the second connecting rod 446 away from the rectangular frame 41 is also provided with a limiting opening 445 corresponding to the position of the limiting plate 443. When the flip cover 42 is perpendicular to the rectangular frame 41, the limiting plate 443 will be inserted into the limiting opening 445 downward by the gravity of the flip cover 42, and at this time, the first connecting rod 441 is located on the inner surface of the straight groove 442 near the connecting block 421. Therefore, when the user needs to inspect the control module 4, the user can first push the flip cover 42 upward, so that the limiting piece 443 can be inserted downward into the limiting opening 445 under the gravity of the flip cover 42, so that the limiting opening 445 can clamp the limiting piece 443, so that the first connecting rod 441 and the second connecting rod 446 are located on the same straight line, thereby supporting the flip cover 42 to prevent it from falling (such as Fig.18 state).

[0054] Therefore, the specific implementation of this embodiment is as follows: when installing the charging module 5 of this charging pile, the four partitions 51 can be installed first, and the partitions 51 can be fixedly installed with the corresponding mounting rods 110 or the first cover plate 16 by bolts, and then the rear baffles 58 on both sides are installed. At this time, the multiple front baffles 56 with the charging module 54 can be directly pushed into the corresponding positions in turn, and the front baffles 56 and the limit strips 52 and the mounting rods 110 located at the front side are fixedly connected by bolts;

[0055] When installing the control module 4, the power module 43, the main board 45, and the power control unit 46 can be pre-connected outside the charging pile, and then the installed control module 4 is pushed into the device chassis 1 along the second bearing plate 15, and then the gun wires of the charging gun are connected to the power control unit 46 from both sides, and finally the insulating plate 11 is installed. This can avoid wiring most accessories in the device chassis 1, and the modular structure of first completing the wiring of the control module 4 can improve the work efficiency of the installer;

[0056] When the user needs to inspect the control module 4, the user can first push the flip cover 42 upwards, so that the limiting piece 443 will be inserted downward into the limiting opening 445 due to the gravity of the flip cover 42, so that the limiting opening 445 will clamp the limiting piece 443, so that the first connecting rod 441 and the second connecting rod 446 are located in the same straight line, thereby supporting the flip cover 42 to prevent it from falling. Embodiment 2

[0057] This embodiment further improves the device chassis 1 and the rear chassis door 3 on the basis of the first embodiment, so as to solve the problem of high noise during the operation of the charging pile.

[0058] Specifically, Figure 5-Figure 7 As shown, the upper parts of the ends of the two mounting plates 13 away from each other are fixedly connected with the second cover plate 17, the rear parts of the ends of the two mounting plates 13 away from each other are fixedly connected with the first cover plate 16, the ends of the two first cover plates 16 and the two second cover plates 17 away from the corresponding mounting plates 13 are fixedly connected to the inner wall of the device chassis 1, and the upper front sides of the two second cover plates 17 are fixedly connected with the sealing plate 18. When the control module 4 and the charging module 5 have been installed in the device chassis 1, due to the presence of the mounting plate 13, the first cover plate 16, the second cover plate 17 and the sealing plate 18, the inner cavity of the device chassis 1 will be divided into two relatively independent spaces, front and back. The air entering the device chassis 1 can only be transported from front to back from the position of the cooling fan 55 to cool the charging module 54.

[0059] In addition, the middle of the rear end of the two sealing plates 18 is fixedly connected with a support rod 19, and the rear of the end of the two support rods 19 close to each other is fixedly connected with a baffle 191, and the middle of the upper end of the second carrier plate 15 is fixedly connected with a baffle 151 located in the same plane as the two baffles 191, and the rear end of the rectangular frame 41 is fixedly connected with the two baffles 191 and the baffle 151, so when installing the control module 4, the installer directly pushes the control module 4 backward at the upper end of the second carrier plate 15 into the equipment chassis 1 until it contacts the baffle 151 and the baffle 191. The front end of the insulating plate 11 is fixedly connected with the two baffles 191 and the baffle 151, and the left and right ends of the insulating plate 11 are in contact with the left and right sides of the inner wall of the equipment chassis 1, and the insulating plate 11 is used to block the front and rear air flow at the upper part of the inner cavity of the equipment chassis 1.

[0060] like Fig.19 As shown, the front end of the rear chassis door 3 is fixedly connected with a sealing cover 33, and there is an independent cavity between the sealing cover 33 and the rear chassis door 3. An exhaust fan unit 34 is provided at the upper front end of the sealing cover 33, and an air outlet 31 communicating with the front and rear is provided at the lower rear end of the rear chassis door 3. An inclined guide plate 32 is also fixedly installed at the upper front end of the rear chassis door 3. The material of the guide plate 32 is sound insulation material. Through the sound insulation effect of the rear side of the charging pile, the guide plate 32 is located on the rear side of the sealing cover 33. Therefore, when the exhaust fan unit 34 is working, the airflow direction in the rear chassis door 3 is as shown in the figure: first, the exhaust fan unit 34 will draw the air in the equipment chassis 1 into the gap between the sealing cover 33 and the rear chassis door 3, and then the air will move downward along the guide plate 32 to the air outlet 31 for discharge.

[0061] like Figure 3As shown, a sound insulation board 21 is provided at the rear end of the front chassis door 2. The material of the sound insulation board 21 is sound insulation material. The ends of the two mounting plates 13 that are away from each other are provided with sound insulation cotton, which can further improve the sound insulation effect of the front side and the left and right sides of the charging pile.

[0062] Therefore, the overall air flow direction inside the charging pile is as follows: Fig. 20 and Fig.21 As shown: First, with the simultaneous operation of multiple cooling fans 55, the outside air will first enter the interior of the device chassis 1 from the air inlet 12. Due to the obstruction of the mounting plate 13, the first cover plate 16, the second cover plate 17, and the sealing plate 18, the air can only be drawn into the charging module 5 from the front side, thereby achieving a cooling effect on the charging module 54. Then, the negative pressure generated by the operation of the exhaust unit 34 will draw out the air entering the charging module 54 and move it upward. The exhaust unit 34 will draw the air in the device chassis 1 into the gap between the sealing cover 33 and the rear chassis door 3. Then, the air will move downward along the guide plate 32 to the air outlet 31 for discharge.

[0063] Therefore, the specific implementation of this embodiment is as follows: the charging pile, by providing the mounting plate 13, the first cover plate 16, the second cover plate 17, and the sealing plate 18, divides the inner cavity of the equipment chassis 1 into two relatively independent spaces at the front and rear, and by providing the sealing cover 33, an independent cavity is provided between the sealing cover 33 and the rear chassis door 3;

[0064] When the charging pile is working, under the action of multiple cooling fans 55 working simultaneously, the outside air will first enter the inside of the equipment chassis 1 from the air inlet 12. Due to the obstruction of the mounting plate 13, the first cover plate 16, the second cover plate 17, and the sealing plate 18, the air can only be drawn into the charging module 5 from the front side, so as to achieve the cooling effect of the charging module 54. Then, the negative pressure generated by the operation of the exhaust unit 34 will draw out the air entering the charging module 54 and move it upward. The exhaust unit 34 will draw the air in the equipment chassis 1 into the gap between the sealing cover 33 and the rear chassis door 3. Then, the air will move downward along the guide plate 32 to the air outlet 31 for discharge.

[0065] In summary, after entering the charging pile, the air will continuously and tortuously pass through multiple cavities. On the one hand, the air can fully pass through various components in the device chassis 1 to form a cooling effect. On the other hand, by setting multiple sound insulation boards, the noise generated in the device chassis 1 is reduced to a certain extent. The sound can only be transmitted mainly through the air. After entering the charging pile, the air will pass through a continuously tortuous channel into each cavity, so that the sound energy of the noise is dispersed and dissipated, thereby reducing the intensity of the noise.
