Description

Technical Field

[0001] This invention relates to the field of vehicle charging pile technology, specifically to a new energy vehicle charging pile that can dissipate heat evenly. Background Technology

[0002] New energy vehicle charging stations are specialized equipment that provides electrical replenishment for new energy vehicles such as electric vehicles and hybrid vehicles, similar to gas stations for traditional gasoline vehicles. They are a core component of new energy vehicle infrastructure, directly impacting the user's charging experience and the convenience of vehicle use.

[0003] Patent CN212737800U discloses an internal self-heating structure for a new energy vehicle charging pile, relating to the field of charging pile technology. The structure includes a charging pile housing, characterized in that a lead screw is rotatably connected to the inner wall of the housing via a bearing, and a second gear is fixedly connected to one end of the lead screw's outer surface. This internal self-heating structure, through the arrangement of a micro-motor, a first gear, a second gear, a lead screw, a threaded block, and an electric fan, enables the electric fan to reciprocate left and right, effectively dissipating heat from inside the charging pile housing through heat dissipation holes, thus improving heat dissipation efficiency. The arrangement of a water tank, a first connecting pipe, a water pump, a second connecting pipe, a delivery pipe, a condenser pipe, and openings further facilitates effective heat absorption on the outer and inner walls of the charging pile housing, thereby rapidly achieving a cooling effect and extending the charging pile's service life.

[0004] However, the aforementioned device is difficult to seal when not in use, which can easily lead to dust, debris, and insects entering the device and causing short circuits inside, thus affecting the device's service life. Therefore, a new energy vehicle charging pile that can dissipate heat evenly is proposed to solve the above-mentioned problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a new energy vehicle charging pile that can dissipate heat evenly, in order to address the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a new energy vehicle charging pile with uniform heat dissipation, including a base, a box fixedly connected to the top of the base, a charging module installed inside the box, a sealing mechanism and a winding mechanism provided on the inner wall of the box, a door hinged to the back of the box, a maintenance mechanism provided on the inner wall of the door, a protective mechanism provided on the front of the box, an air outlet on the left side of the box, an air inlet on the right side of the box, and an exhaust fan fixedly connected to the surface of the air outlet on the left side of the box. The sealing mechanism includes: a mounting plate, a sealing plate, an air inlet grille, a filter plate, a connecting rod, an air intake fan, a multi-fold sealing plate, and a connecting arm. The mounting plate is fixedly connected to the inner wall of the housing on one side of the housing's air inlet. The sealing plate is rotatably connected to the inner wall of the mounting plate. The air inlet grille is hinged to the top of the right air inlet of the housing. The filter plate is installed on the back of the air inlet grille. The connecting rod is movably connected to the side of each sealing plate away from the mounting plate. The air intake fan is fixedly connected to the right air inlet of the housing's inner wall. The multi-fold sealing plate is hinged to the inner wall of the left air outlet of the housing. The connecting arm is hinged to the surface of the multi-fold sealing plate. Each multi-fold sealing plate has a magnetic block inside for fixing it to the housing. The air intake fan is located between the inner wall of the housing and the sealing plate. The front of the housing has a communication opening. The sealing plate is driven to open and close by a motor inside the mounting plate. When the device is charging an external vehicle, the winding mechanism loosens the cable, allowing the user to pull the charging gun cable out of the device. As the winding mechanism operates, the slider moves, causing the multi-fold sealing plate to fold. With each movement, the multi-fold sealing plate folds open to create an air vent grille. Meanwhile, the sealing plate is flipped open by the motor inside the mounting plate. Then, the intake fan starts, drawing in outside air, filtering it through the filter plate, and then dissipating heat from the charging module. The air is then discharged through the exhaust grille, forming a heat exchange cycle to evenly dissipate heat from the device. After charging is complete, the sealing plate closes to seal the device, effectively preventing dust, debris, and insects from entering the box, avoiding dust accumulation on internal components, and reducing the need for cleaning and maintenance. The sealing plate can also guide the intake air, optimizing the internal airflow and precisely directing cool air to the surface of the heating elements of the charging module, thus improving heat dissipation efficiency.

[0007] Preferably, the winding mechanism includes: a mounting base, a fixing plate, an electric slide rail, a slider one, a pulley one, a pulley two, and a cable. The mounting base is fixedly connected to the inner wall of the housing, the fixing plate is fixedly connected to the inner wall of the housing, the electric slide rail is fixedly connected between the mounting base and the fixing plate, the slider one is fixedly connected to the output end of the electric slide rail, the pulley one is rotatably connected to the axis of the slider one, the pulley two is rotatably connected to the inner wall of the housing, one end of the cable is fixedly connected to the back of the charging module, the surface of the slider one is hinged to the connecting arm, the cable is coiled between each pulley one and pulley two, and the other end of the cable is connected to the charging gun outside the housing. After the device completes charging of an external vehicle and the charging gun is plugged back in, the winding mechanism operates, and the pulley two is moved from inside the mounting base. The motor drives the cable to rotate counterclockwise, causing it to retract. Simultaneously, the electric slide rail drives the slider to move to the left, tightening the cable and guiding it back into the device via the top pulley. This prevents the cable from scattering on the ground, reducing the risk of tripping over users. It also prevents the cable from being run over or pulled by vehicles or exposed to sunlight for extended periods, reducing the risk of sheath aging and breakage and extending cable life. As the slider moves, it also pushes the connecting arm, which in turn folds the multi-fold sealing plate back onto the surface of the air outlet grille. By winding the cable in an S-shape between pulleys one and two, it effectively prevents the cable from tangling and knotting, avoiding damage to the internal core of the cable caused by tangling. Compared to traditional reel reels, the horizontal S-shaped winding makes full use of the flat space inside the charging pile, reducing space occupation.

[0008] Preferably, the convenient maintenance mechanism includes: a fixed block, a threaded rod, a rotating rod, a pull rod, a second slider, a guide rail, a nut push rod, a limiting rod, and a lever. The fixed block is fixedly connected to the inner wall of the box. The threaded rod is rotatably connected to the bottom of the fixed block. The rotating rod is fixedly connected to the circumferential surface of the threaded rod. One end of the pull rod is hinged to the end of the rotating rod away from the threaded rod. The guide rail is fixedly connected to the inner wall of the box door. The second slider is slidably connected to the inner wall of the guide rail. The nut push rod is movably connected to the end of the threaded rod away from the fixed block through an internal threaded groove. The limiting rod is fixedly connected to the bottom of the partition on the inner wall of the box. The lever is rotatably connected to the inner wall of the housing, with one end of the lever contacting the air inlet grille and the other end contacting the nut push rod. The other end of the lever is rotatably connected to the inner wall of the slider. The threaded rod has a threaded groove on its circumferential surface, and the nut push rod has a guide groove on its surface. The limiting rod is slidably connected to the guide groove on the surface of the nut push rod. The protective mechanism includes: a charging gun cover, a cover plate, a locking block, and a baffle. The charging gun cover is fixedly connected to the front of the housing, the cover plate is hinged to the top of the front of the charging gun cover, the locking block is slidably connected to the inner wall of the communication opening on the front of the housing, and the baffle is slidably connected to... The locking block is attached to the inner wall of the front connecting opening of the housing to seal the housing. When in its initial position, the locking block engages with the notch on the cover surface. The back of the locking block is fixedly connected to the slider. The baffle is fixedly connected to the locking block. Before the device starts charging, the cover is locked to the surface of the charging gun cover by the locking block and cannot be opened, thus protecting the charging gun from damage caused by human error or severe weather. After the user unlocks the cover, the winding mechanism starts, and the slider moves to the right to loosen the cable, causing the locking block to move away from the cover. The cover is then unrestrained and opens, allowing the charging gun to be pulled out for charging. This mechanism is also used for maintenance and upkeep of the device. Opening the door causes the guide rail to rotate, which in turn moves the second slider. The second slider then moves the pull rod, which in turn pulls the rotating rod to rotate. The rotating rod, through the bottom thread, causes the nut push rod to rotate. Because the nut push rod is constrained by the limiting rod, it can only move downwards. The downward movement of the nut push rod pushes the lever to rotate, and the rotation of the lever lifts the air intake grille, making it convenient for maintenance personnel to replace the filter plate at the bottom of the air intake grille. Opening the door opens the air intake grille simultaneously, simplifying the operation steps and increasing the speed of filter plate replacement. In the process of maintaining and repairing large-scale charging piles, this significantly improves replacement efficiency and reduces labor costs.

[0009] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This new energy vehicle charging pile, which can dissipate heat evenly, can effectively prevent dust, debris, and insects from entering the box, avoid dust accumulation on internal components, and reduce the need for cleaning and maintenance. Through the sealing plate, it can also guide the intake air, optimize the internal airflow, and accurately guide the cool air to the surface of the heat-generating components of the charging module to improve heat dissipation efficiency.

[0010] 2. This new energy vehicle charging pile, which can dissipate heat evenly, can prevent cables from scattering on the ground, reducing the risk of tripping over users. It can also prevent cables from being run over or pulled by vehicles or exposed to sunlight for a long time, reducing the risk of outer sheath aging and breakage, extending the cable life. It can also effectively prevent cables from tangling and knotting, avoiding damage to the internal core of the cable caused by tangling. Compared with traditional reel, the horizontal S-shaped winding makes full use of the flat space inside the charging pile, reducing space occupation.

[0011] 3. This new energy vehicle charging pile, which can dissipate heat evenly, can protect and prevent the charging gun from being damaged by human error or severe weather. It can also open the air intake grille at the same time as opening the box door, simplifying the operation steps and improving the speed of filter plate replacement. In the process of maintaining and repairing large-scale charging piles, it can greatly improve the replacement efficiency and reduce labor costs. Attached Figure Description

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] Please see Figures 1-15One embodiment of the present invention is as follows: a new energy vehicle charging pile with uniform heat dissipation, including a base 1, a box 2 fixedly connected to the top of the base 1, a charging module 3 installed inside the box 2, a sealing mechanism 4 and a winding mechanism 5 provided on the inner wall of the box 2, a door 8 hinged to the back of the box 2, a maintenance mechanism 6 provided on the inner wall of the door 8, a protective mechanism 7 provided on the front of the box 2, an air outlet on the left side of the box 2, an air inlet on the right side of the box 2, an air outlet grille 9 fixedly connected to the surface of the air outlet on the left side of the box 2, and the sealing mechanism 4 including: a mounting plate 401, a sealing plate 402, an air inlet grille 403, a filter plate 404, a connecting rod 405, an air intake fan 406, a multi-fold sealing plate 407, and a connecting arm 408. The mounting plate 401 is fixedly connected to the inner wall of the box 2 on the side of the air inlet of the box 2, the sealing plate 402 is rotatably connected to the inner wall of the mounting plate 401, and the air inlet grille 403 is hinged to the door 405. At the top of the air inlet on the right side of the housing 2, a filter plate 404 is installed on the back of the air inlet grille 403. A connecting rod 405 is movably connected to the side of each sealing plate 402 away from the mounting plate 401. An intake fan 406 is fixedly connected to the air inlet on the right side of the inner wall of the housing 2. A multi-fold sealing plate 407 is hinged to the inner wall of the air outlet on the left side of the housing 2. A connecting arm 408 is hinged to the surface of the multi-fold sealing plate 407. Each multi-fold sealing plate 407 has a magnetic block inside for fixing to the housing 2. The intake fan 406 is located between the inner wall of the housing 2 and the sealing plate 402. A connecting opening is provided on the front of the housing 2. The sealing plate 402 is driven to open and close by a motor inside the mounting plate 401, which can effectively prevent dust, debris, and insects from entering the housing, avoid dust accumulation on internal components, and reduce cleaning and maintenance needs. The sealing plate 402 can also guide the intake air, optimize the internal airflow, and accurately guide the cold air to the surface of the heating element of the charging module 3 to improve heat dissipation efficiency.

[0016] Working principle: When the device is charging an external vehicle, the winding mechanism 5 loosens the cable, allowing the user to pull the charging gun cable out of the device. As the winding mechanism 5 operates, the slider 504 moves, causing the multi-fold sealing plate 407 to fold. As the slider 504 moves, the multi-fold sealing plate 407 folds open the air outlet grille 9. At the same time, the sealing plate 402 is driven to flip open by the motor inside the mounting plate 401. Subsequently, the intake fan 406 starts, drawing in external air, filtering it through the filter plate 404, and then cooling the charging module 3. The air is then discharged through the air outlet grille 9, forming a heat exchange cycle to evenly cool the device. After charging is complete, the sealing plate 402 closes to seal the device, effectively preventing dust, debris, and insects from entering the box, avoiding dust accumulation on internal components, and reducing cleaning and maintenance needs. The sealing plate 402 also guides the intake air, optimizing internal airflow and precisely directing cool air to the surface of the heating elements of the charging module 3, improving heat dissipation efficiency.

[0017] Please see Figures 1-15Based on the above embodiments, in another embodiment of the present invention, the winding mechanism 5 includes: a mounting base 501, a fixing plate 502, an electric slide rail 503, a first slider 504, a first pulley 505, a second pulley 506, and a cable 507.

The end is fixedly connected to the back of the charging module 3. The surface of slider 1 504 is hinged to the connecting arm 408. The cable 507 is interlaced and coiled between each pulley 1 505 and pulley 2 506. The other end of the cable 507 is connected to the external charging gun of the box 2. This can prevent the cable from falling to the ground, reduce the risk of tripping over users, and also prevent the cable from being run over or pulled by vehicles or exposed to sunlight for a long time, reducing the risk of outer sheath aging and breakage, extending the cable life. It can also effectively prevent the cable from tangling and knotting, avoiding damage to the internal core of the cable caused by tangling. Compared with the traditional reel, the horizontal S-shaped coiling makes full use of the flat space inside the charging pile and reduces space occupation.

[0018] The maintenance mechanism 6 includes: a fixed block 601, a threaded rod 602, a rotating rod 603, a pull rod 604, a slider 605, a guide rail 606, a nut push rod 607, a limit rod 608, and a lever 609. The fixed block 601 is fixedly connected to the inner wall of the housing 2. The threaded rod 602 is rotatably connected to the bottom of the fixed block 601. The rotating rod 603 is fixedly connected to the circumferential surface of the threaded rod 602. One end of the pull rod 604 is hinged to the end of the rotating rod 603 away from the threaded rod 602. The guide rail 606 is fixedly connected inside the door 8. The slide block 605 is slidably connected to the inner wall of the guide rail 606. The nut push rod 607 is movably connected to the end of the threaded rod 602 away from the fixed block 601 through an internal threaded groove. The limit rod 608 is fixedly connected to the bottom of the partition plate on the inner wall of the housing 2. The toggle block 609 is rotatably connected to the inner wall of the housing 2, with one end of the toggle block 609 contacting the air inlet grille 403 and the other end of the toggle block 609 contacting the nut push rod 607. The other end of the pull rod 604 is rotatably connected to the inner wall of the slide block 605. The circumferential surface of the threaded rod 602 has a... The nut push rod 607 has a threaded groove, and a guide groove is formed on its surface. The limiting rod 608 is slidably connected in the guide groove on the surface of the nut push rod 607. The protective mechanism 7 includes: a charging gun cover 701, a cover plate 702, a locking block 703, and a baffle 704. The charging gun cover 701 is fixedly connected to the front of the housing 2. The cover plate 702 is hinged to the top of the front of the charging gun cover 701. The locking block 703 is slidably connected to the inner wall of the front connecting opening of the housing 2. The baffle 704 is slidably connected to the inner wall of the front connecting opening of the housing 2 for sealing. When the sealing box 2 and the locking block 703 are in the initial position, they are engaged with the notch on the surface of the cover plate 702. The back of the locking block 703 is fixedly connected to the slider 504. The baffle 704 is fixedly connected to the locking block 703. This can protect the charging gun and prevent it from being damaged by human error or severe weather. It can also open the air inlet grille 403 at the same time as opening the box door 8, simplifying the operation steps and improving the replacement speed of the filter plate 404. In the process of maintaining and repairing large-scale charging piles, it can greatly improve the replacement efficiency and reduce labor costs.

[0019] Working principle: After the device completes charging of an external vehicle and the charging gun is plugged back in, the winding mechanism 5 operates. The pulley 2 506 is driven by the motor inside the mounting base 501 to rotate counterclockwise, driving the cable to retract. At the same time, the electric slide rail 503 drives the slider 1 504 to move to the left to tighten the cable. The cable is then guided back into the device through the top pulley 2 506. This prevents the cable from scattering on the ground, reducing the risk of tripping over users. It also prevents the cable from being run over or pulled by vehicles or exposed to sunlight for a long time, reducing the risk of outer sheath aging and breakage and extending the cable's lifespan. While the slider 1 504 moves, it also pushes the connecting arm 408 to move. The moving connecting arm 408 pushes the multi-fold sealing plate 407 to fold back onto the surface of the air outlet grille 9. By winding the cable in an S-shape between the pulley 1 505 and the pulley 2 506, it can effectively prevent the cable from tangling and knotting, avoiding damage to the internal core of the cable caused by tangling. Compared with traditional winding reels, the horizontal S-shaped winding makes full use of the flat space inside the charging pile and reduces space occupation.

[0020] Before the device starts charging, the cover 702 is locked to the surface of the charging gun cover 701 by the locking block 703 and cannot be opened. This protects the charging gun and prevents it from being damaged by human error or severe weather. After the user unlocks it, the winding mechanism 5 starts, and the slider 504 moves to the right to loosen the cable, causing the locking block 703 to move away from the cover 702. The cover 702 is then unrestrained and opens, allowing the charging gun to be pulled out for charging. When the device is being maintained, opening the cabinet door 8 causes the guide rail 606 to rotate. The rotation of the guide rail 606 causes the slider 605 to move, which in turn causes the pull rod 604 to move. The movement of 604 pulls the rotating rod 603 to rotate. The rotation of the rotating rod 603 drives the nut push rod 607 to rotate through the bottom thread. Due to the constraint of the limiting rod 608, the nut push rod 607 can only move downward. The downward movement of the nut push rod 607 pushes the toggle block 609 to rotate. The rotation of the toggle block 609 lifts the air intake grille 403, making it convenient for maintenance personnel to replace the filter plate 404 at the bottom of the air intake grille 403. The air intake grille 403 opens at the same time when the box door 8 is opened, simplifying the operation steps and improving the replacement speed of the filter plate 404. In the process of maintenance of large-scale charging piles, the replacement efficiency is greatly improved and the labor cost is reduced.
