Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicle charging piles, and specifically to a new energy vehicle charging pile with a heat dissipation mechanism. Background Art

[0002] A charging pile refers to an energy charging device that provides charging services for new energy vehicles. With the popularization of new energy electric vehicles, new energy electric vehicle charging piles will surely become the focus of the development of the new energy industry. The large-scale investment in new energy charging piles enables new energy electric vehicles to be quickly charged, just like a car gas station, and can provide charging and energy storage for new energy electric vehicles. The charging equipment is an important guarantee in the electric vehicle industrial chain. The charging pile can be fixed on the ground or the wall and installed in public scenarios (commercial buildings, parking lots, charging stations, etc.) to escort the popularization of electric vehicles.

[0003] The existing electric vehicle charging piles assembled in charging stations are all high-power DC charging piles. Although the high-power feature of the DC charging pile can reduce the charging time, the excessive power brings great pressure to the heat dissipation of the charging pile, which is one of the main reasons for the failure of the DC charging pile. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: A new energy vehicle charging pile with a heat dissipation mechanism, including a cabinet body, and a main body fixedly installed inside the cabinet body. A wire is fixedly connected to the bottom of the main body, and the wire penetrates through the cabinet body;

[0005] A ventilation component, the ventilation component is fixedly installed on the outer side of the cabinet body, and a fan is fixedly connected to one side of the cabinet body close to the ventilation component;

[0006] A charging component, the charging component is snap-fitted and installed on the outer side of the cabinet body close to the ventilation component, and the charging component is fixedly connected to the end of the wire away from the main body;

[0007] Among them, the ventilation component includes a frame which is fixedly connected to the cabinet body and embedded inside the cabinet body. The left fan of the power distribution cabinet operates to suck in the cold air from the outside, so that the cold air enters the inside of the power distribution cabinet through the left ventilation component, thereby absorbing the heat inside the power distribution cabinet. Subsequently, the right fan operates, so that the hot air after absorbing the heat is discharged through the right ventilation component, forming an air convection path of left-in and right-out, taking away the heat generated by the equipment operation, avoiding too high internal temperature, reducing the aging and failure risks of electrical components caused by high temperature, and prolonging the equipment life. An inclined plate is arranged inside the frame, and a square plate is fixedly connected to the end of the inclined plate. When the rainwater impacts the outside of the inclined plate, the rainwater flows outward, so that the rainwater drips vertically along the outside of the square plate, away from the inside of the louver, reducing the risk of secondary splashing. A baffle is fixedly connected to the end of the inclined plate away from the square plate. A vertical baffle is added on the side of the inclined plate close to the inside of the equipment, which can form an L-shaped blocking structure. When the rainwater slides down along the outside of the inclined plate, the vertical baffle can intercept a small amount of splashed rainwater to prevent it from directly entering the inside of the power distribution cabinet. At the same time, when the cold air enters the inside of the power distribution cabinet through the adjacent inclined plates, after the dust particles in the cold air impact the inclined plate with the airflow, the vertical baffle can change the airflow direction, so that the heavier particles settle due to inertia, reducing the internal dust accumulation. The number of the inclined plates is multiple, and the multiple inclined plates are evenly arranged inside the frame. The baffle and the square plate are vertically arranged.

[0008] Preferably, the number of the fans is two, the number of the ventilation components is two, the two ventilation components are symmetrically arranged on the left and right sides of the cabinet body, the number of the wires is two, the two wires are symmetrically arranged on the left and right sides of the cabinet body, and the number of the charging components is two, the two charging components are symmetrically arranged on the left and right sides of the cabinet body.

[0009] Preferably, a frame is fixedly connected to the side of the inner wall of the frame, and a fixing block is fixedly connected to the outside of the frame. There are two frames, and the two frames are symmetrically arranged with the inclined plate as the center. Fixing blocks are fixedly connected to the opposite sides of the frames. The fixing blocks and the L-shaped plates are made of plastic. During installation, by means of the fixing blocks and the L-shaped plates provided on the two frames on both sides, the slight deformation of the fixing blocks and the L-shaped plates is utilized to clamp the inclined plate. At this time, the up-and-down displacement, left-and-right swing, and front-and-back rotation of the inclined plate can be restricted, avoiding wear or deformation caused by direct hard contact of metal parts. At the same time, when the fan is running, the fan will drive the airflow to impact the inclined plate. At this time, the elasticity of the plastic fixing blocks and the L-shaped plates provided at both ends of the inclined plate can buffer high-frequency vibrations, reducing the risk of abnormal noise or loosening of the inclined plate caused by resonance. There are multiple fixing blocks, and the multiple fixing blocks are vertically and evenly arranged on the frame. The square plate is located at the interval between two adjacent fixing blocks. An L-shaped plate is fixedly connected to the side of the frame away from the fixing block. There are multiple L-shaped plates, and the multiple L-shaped plates are vertically and evenly arranged on the frame. The L-shaped plate is located at the interval between the two frames. The connection part between the inclined plate and the baffle is located inside the L-shaped plate close to the fixing block. A flow guide plate is fixedly connected to the bottom of the inner wall of the frame. A trapezoidal groove is opened in the middle of the top of the flow guide plate. When it rains, after the rain hits the outside of the inclined plate, it flows along the outside of the inclined plate to the outside of the cabinet body. Some of the splashed rainwater flows downward and falls on the flow guide plate. Due to the structure design of the trapezoidal groove with a wider top and a narrower bottom, the wide opening at the top is convenient for quickly collecting rainwater at this time. The collected rainwater is discharged from the feeding hole at the bottom of the trapezoidal groove, thereby avoiding the accumulation of water on the bottom surface of the frame. A feeding hole is opened at the bottom of the trapezoidal groove, and there are multiple feeding holes, and the multiple feeding holes are evenly arranged on the flow guide plate.

[0010] Preferably, the cabinet body includes a housing. Through holes are provided on the left and right sides of the housing. The frame is located inside the through holes. A fixing member is fixedly connected to one side of the housing close to the through holes. A partition is fixedly connected to the inner wall of the housing. When the left fan of the power distribution cabinet works, it sucks in the cold air from the outside, so that the cold air enters the interior of the power distribution cabinet through the left ventilation component. The cold air moves along the space between the main body and the housing towards the through hole at the air outlet end. During the flow of the cold air, it contacts the main body, thereby absorbing heat from the main body. Subsequently, the right fan works, so that the hot air after absorbing heat is discharged through the right ventilation component. By arranging a partition in the space between the main body and the housing, at this time, the partition divides the space between the housing and the main body into multiple parallel gaps, forming a flow guiding structure for the heat sink, avoiding poor heat dissipation caused by air flow disorder. The number of partitions is multiple, and the partitions are located on the adjacent surfaces of the housing close to the through holes. The number of fixing members is two, and the two fixing members are symmetrically arranged on the left and right sides of the housing. A fixing ring is fixedly connected to the outside of the housing. The wire passes through the housing through the fixing ring. A connecting plate is fixedly connected to the inner wall of the fixing ring. The connecting plate is designed in a U shape, and the two sides of the connecting plate are inclined. The outside of the wire contacts the roller. By arranging the roller, rolling friction is used to replace sliding friction, reducing the friction between the wire and the housing and reducing frictional loss. At the same time, the axes of the two rollers at both ends of the connecting plate are parallel, thus forming a linear guiding channel to ensure that the wire always moves along the axis of the fixing ring during movement, avoiding winding or jamming caused by deviation. The end of the connecting plate is rotatably connected to the roller. The number of rollers is two, and the two rollers are arranged at both ends of the connecting plate. The number of connecting plates is three, and the three connecting plates are evenly distributed circumferentially around the fixing ring.

[0011] Preferably, the fixing member includes a support block. The support block is fixedly connected to the housing and is located inside the housing. An inner cavity is provided inside the support block. The opening of the inner cavity is located at one end of the support block away from the main body. A socket is fixedly connected to the middle of the bottom of the inner wall of the inner cavity. The socket is designed in a hexagon shape. A cylinder is fixedly connected to the inside of the socket. The number of cylinders is multiple. The outer side of one end of the cylinder close to the inner wall of the inner cavity is designed with an inclined edge to avoid the hard blockage of the right-angle edge to the fixing seat, reducing the friction and jamming during insertion and extraction and improving the operation smoothness. Two card slots are provided in the middle of the bottom of the inner side of the inner cavity. The two card slots are symmetrically arranged with the socket as the center. A convex block is fixedly connected to the inner side of the inner cavity. The convex block is located on the adjacent side of the card slot. The number of convex blocks is multiple, and the multiple convex blocks are symmetrically arranged with the socket as the center.

[0012] Preferably, the charging assembly includes a handle. A fixing seat is fixedly connected to the end of the handle. One end of the handle away from the fixing seat is fixedly connected to an electric wire. A sliding groove is formed on the outer side of the fixing seat. The sliding grooves are symmetrically arranged on both sides of the fixing seat. The convex block is located inside the sliding groove. In the middle of the end of the fixing seat away from the handle, a plug is fixedly connected. The charging assembly is installed inside the fixing member, so that the fixing seat slides inside the inner cavity through the convex block and the sliding groove. At the same time, the rotating plate contacts and is squeezed by the inner wall of the inner cavity, and the Z-shaped plate is compressed by force, so that the fixing seat drives the rotating plate into the inner part of the inner cavity. At this time, the cylinder is located inside the round hole. When the fixing seat moves to the bottom of the inner wall of the inner cavity, by using the elastic performance of the Z-shaped plate, the rotating plate rotates so that the clamping block is located inside the clamping groove, and the charging assembly is clamped on the cabinet body. A round hole is formed at the end of the plug away from the handle, and the cylinder is located inside the round hole. A through groove is formed in the adjacent surface of the fixing seat close to the sliding groove. A rotating plate is rotatably connected inside the through groove. A clamping block is fixedly connected to the outer side of the end of the rotating plate. The clamping block is located inside the clamping groove. A Z-shaped plate is fixedly connected to the side of the rotating plate away from the clamping block. The Z-shaped plate has elasticity. One end of the Z-shaped plate away from the rotating plate is fixedly connected to the inner wall of the through groove. A square hole is formed in the fixing seat close to the handle. The number of the square holes is two. The two square holes are symmetrically arranged at the upper and lower ends of the handle. A limiting block is slidably connected inside the square hole. The opposite ends of the two limiting blocks are inclined. The limiting block has magnetism, and the magnetisms between the two limiting blocks are opposite. The limiting block is located at the end of the rotating plate away from the clamping block. An inclined groove is formed inside the handle close to the fixing seat. The inclined grooves are symmetrically arranged on the handle. The user holds the handle. The user contacts and squeezes the arc plates at the upper and lower ends of the handle, so that the arc plates drive the pressing block to move towards the inclined groove under force. The pressing block contacts and is squeezed by the sliding block, so that the sliding block moves away from the pressing block under the squeezing force. Thus, the sliding block squeezes the inclined end of the limiting block, so that the limiting block moves towards the through groove, and further the limiting block contacts the bottom of the rotating plate. At this time, the rotating plate is rotated by force, so that the clamping block is away from the clamping groove, and the charging assembly can be taken down smoothly. Then charging is carried out. The inclined groove is communicated with the square hole. A sliding block is slidably connected to the inner wall of the inclined groove. One end of the sliding block close to the pressing block is inclined. The number of the sliding blocks is two. The two are symmetrically arranged at the upper and lower ends of the handle. A pressing block is slidably connected inside the handle. The pressing block penetrates through the handle and extends into the inclined groove. An arc plate is fixedly connected to the end of the pressing block away from the inclined groove.

[0013] The present invention provides a new energy vehicle charging pile with a heat dissipation mechanism. It has the following beneficial effects:

[0014] 1. For this new energy vehicle charging pile with a heat dissipation mechanism, when the fan on the left side of the power distribution cabinet operates, it sucks in the cold air from the outside, allowing the cold air to enter the interior of the power distribution cabinet through the left ventilation component, thereby absorbing the heat inside the power distribution cabinet. Subsequently, the fan on the right side operates, enabling the hot air after absorbing heat to be discharged through the right ventilation component, forming an air convection path of entering from the left and exiting from the right, taking away the heat generated during the operation of the equipment and preventing the internal temperature from being too high.

[0015] 2. For this new energy vehicle charging pile with a heat dissipation mechanism, by adding a vertical baffle on the side of the inclined plate close to the interior of the equipment, an L-shaped blocking structure can be formed. When rainwater slides down the outside of the inclined plate, the vertical baffle can intercept a small amount of splashed rainwater to prevent it from directly entering the interior of the power distribution cabinet. At the same time, when cold air enters the interior of the power distribution cabinet through the adjacent inclined plates, after the dust particles in the cold air impact the inclined plate with the airflow, the vertical baffle can change the airflow direction, causing the heavier particles to settle due to inertia and reducing the internal dust accumulation.

[0016] 3. For this new energy vehicle charging pile with a heat dissipation mechanism, through the fixing blocks and L-shaped plates provided on both side frames, by utilizing the slight deformation of the fixing blocks and L-shaped plates, the inclined plate can be clamped. At this time, the up-and-down displacement, left-and-right swing, and front-and-back rotation of the inclined plate can be restricted, avoiding wear or deformation caused by direct hard contact of metal parts.

[0017] 4. For this new energy vehicle charging pile with a heat dissipation mechanism, by arranging partitions in the space between the main body and the outer shell, at this time, the partitions divide the space between the outer shell and the main body into multiple parallel gaps, forming a flow guiding structure for the heat dissipation fins, avoiding poor heat dissipation effects caused by air flow disorder.

[0018] 5. For this new energy vehicle charging pile with a heat dissipation mechanism, by setting rollers, using rolling friction to replace sliding friction, reducing the friction between the wire and the outer shell, reducing friction loss. At the same time, the axes of the two rollers at both ends of the connecting plate are parallel, thus forming a linear guiding channel to ensure that the wire always moves along the axis of the fixed ring during movement, avoiding winding or jamming caused by deviation.

[0032] The first embodiment, as Figures 1 to 6 shown, the present invention provides a technical solution: a new energy vehicle charging pile with a heat dissipation mechanism, including a cabinet body 1, and a main body 5 fixedly installed inside the cabinet body 1.

Subsequently, the fan 6 on the right side works, so that the hot air after absorbing heat is discharged from the right ventilation component 2, forming an air convection path of left-in and right-out, taking away the heat generated by the operation of the equipment, avoiding too high internal temperature, reducing the aging and failure risks of electrical components caused by high temperature, extending the service life of the equipment. An inclined plate 22 is arranged inside the frame 21, and a square plate 24 is fixedly connected to the end of the inclined plate 22.

A baffle 23 is fixedly connected to the end of the inclined plate 22 away from the square plate 24. By adding a vertical baffle 23 on the side of the inclined plate 22 close to the inside of the equipment, an L-shaped blocking structure can be formed. When the rain slides down along the outside of the inclined plate 22, the vertical baffle 23 can intercept a small amount of splashed rainwater and prevent it from directly entering the inside of the power distribution cabinet. At the same time, when the cold air enters the inside of the power distribution cabinet through the adjacent inclined plates 22, after the dust particles in the cold air impact the inclined plate 22 with the air flow, the vertical baffle 23 can change the air flow direction, so that the heavier particles settle due to inertia, reducing internal dust accumulation.

A Z-shaped plate 410 is fixedly connected to the side of the rotating plate 48 away from the locking block 49. The Z-shaped plate 410 has elasticity. One end of the Z-shaped plate 410 away from the rotating plate 48 is fixedly connected to the inner wall of the through groove 47. Square holes 411 are formed inside the fixed seat 42 close to the handle 41. The number of the square holes 411 is two. The two square holes 411 are symmetrically arranged at the upper and lower ends of the handle 41. A limiting block 412 is slidably connected inside the square hole 411. The opposite ends of the two limiting blocks 412 are inclined. The limiting block 412 has magnetism, and the magnetism between the two limiting blocks 412 is opposite. The limiting block 412 is located at one end of the rotating plate 48 away from the locking block 49. An inclined groove 413 is formed inside the end of the handle 41 close to the fixed seat 42. The inclined grooves 413 are symmetrically arranged on the handle 41. The user holds the handle 41, and contacts and squeezes between the user and the arc plates 415 at the upper and lower ends of the handle 41, so that the arc plates 415 drive the pressing block 414 to move towards the inclined groove 413 under force. The pressing block 414 contacts and is squeezed by the sliding block 46, so that the sliding block 46 moves in the direction away from the pressing block 414 under the squeezing force. Thus, the sliding block 46 is squeezed by the inclined end of the limiting block 412, so that the limiting block 412 moves towards the through groove 47. Further, the limiting block 412 contacts the bottom of the rotating plate 48. At this time, the rotating plate 48 is rotated under force, so that the locking block 49 is away from the clamping groove 143, and the charging assembly 4 can be taken down smoothly. Then charging is carried out. The inclined groove 413 is communicated with the square hole 411. A sliding block 46 is slidably connected to the inner wall of the inclined groove 413. One end of the sliding block 46 close to the pressing block 414 is inclined. The number of the sliding blocks 46 is two. The two are symmetrically arranged at the upper and lower ends of the handle 41.A pressing block 414 is slidably connected inside the handle 41. The pressing block 414 penetrates through the handle 41 and extends into the inside of the inclined slot 413. One end of the pressing block 414 away from the inclined slot 413 is fixedly connected to an arc plate 415.,

[0041] During use, the charging assembly 4 is installed inside the fixing member 14, so that the fixing base 42 slides inside the inner cavity 142 through the convex block 144 and the sliding slot 43. At the same time, the rotating plate 48 contacts and is squeezed by the inner wall of the inner cavity 142, and the Z-shaped plate 410 is compressed by the force, so that the fixing base 42 drives the rotating plate 48 towards the inside of the inner cavity 142. At this time, the cylinder 146 is located inside the circular hole 45. When the fixing base 42 moves to the bottom of the inner wall of the inner cavity 142, by using the elastic performance of the Z-shaped plate 410, the rotating plate 48 rotates so that the locking block 49 is located inside the clamping groove 143, and the charging assembly 4 is clamped on the cabinet body 1.

[0042] The user holds the handle 41. The user contacts and squeezes between the arc plates 415 at the upper and lower ends of the handle 41, so that the arc plates 415 drive the pressing block 414 to move towards the inclined slot 413 under the force. The pressing block 414 contacts and squeezes the sliding block 46, so that the sliding block 46 moves away from the pressing block 414 under the action of the extrusion force. Thus, the sliding block 46 squeezes between the inclined ends of the limiting block 412, so that the limiting block 412 moves towards the through slot 47. Furthermore, the limiting block 412 contacts the bottom of the rotating plate 48. At this time, the rotating plate 48 is rotated by the force, so that the locking block 49 is away from the clamping groove 143, and the charging assembly 4 can be taken down smoothly and then charged.

[0043] The left fan 6 of the power distribution cabinet works to suck in the cold air from the outside, so that the cold air enters the inside of the power distribution cabinet through the left ventilation assembly 2. The cold air moves along the gap between the main body 5 and the outer shell 11 towards the through hole 12 at the air outlet end. During the flow of the cold air, it contacts the main body 5, thereby absorbing heat from the main body 5. Then the right fan 6 works, so that the hot air after absorbing the heat is discharged from the right ventilation assembly 2.
