Description

Technical Field

[0001] The present invention relates to the field of charging piles, and in particular to a dust-proof and heat-dissipating new energy charging pile. Background Art

[0002] New energy charging piles are devices that provide power supply for new energy vehicles (such as pure electric vehicles, plug-in hybrid vehicles, etc.). Their main components are: charging guns, charging cables, control systems, and display screens. At the same time, new energy charging piles provide convenient charging facilities for new energy vehicles, solve the concerns about the range of new energy vehicles, and promote the popularization and promotion of new energy vehicles.

[0003] For example, the Chinese invention patent with authorization announcement number CN111267657B provides a charging pile, which uses a vortex spring to store the cable of the charging gun, thereby avoiding long-term exposure of the charging gun and the cable to the outside, reducing the erosion of the charging gun and the cable by rain and sunlight, and reducing the risk of human damage. At the same time, in the prior art, a support seat and a metal hoop are usually set at the wiring port of the shell, and the cable is clamped and fixed by the metal hoop and the support seat. In this traditional fixing structure, the metal hoop is easily squeezed and deformed by the cable and loses its binding force, causing the cable to loosen and the installation stability to be poor. The loose cable is easily clamped by the metal hoop when it shakes. The cable will be damaged by cutting the epidermis, resulting in a shortened service life; long-term friction will gradually wear out the insulation layer of the cable and reduce the insulation performance of the cable, which will lead to safety problems such as leakage and short circuit, causing harm to users and vehicles. In addition, long-term friction will damage the conductor inside the cable, resulting in increased resistance. When the resistance increases, more heat will be generated during the charging process, reducing the charging efficiency, and also affecting the battery life. The friction between the cable and the charging pile will also cause wear and scratches on the outer casing of the charging pile, affecting the appearance and service life of the charging pile, especially in outdoor environments, where the worn outer casing is more susceptible to erosion by rain, dust, etc., further reducing the reliability of the charging pile.

[0004] Many charging piles on the market mainly rely on a single radiator for heat dissipation, such as fan cooling or natural convection cooling. These heat dissipation methods are often difficult to effectively dissipate heat when facing high-power charging or high-temperature environments, resulting in an increase in the internal temperature of the charging pile. In order to improve the heat dissipation effect, some charging piles on the market need to add additional heat dissipation equipment, such as air-conditioning systems or liquid cooling devices. This not only increases the cost and complexity of the equipment, but also the additional heat dissipation equipment that needs to be added usually consumes additional energy. At the same time, due to poor heat dissipation, the internal temperature of charging piles on the market is prone to increase, which will lead to accelerated thermal aging of electronic components. Long-term high temperature environment will cause the performance of electronic components to decline, shorten their lifespan, and even cause failures, affecting the normal operation of the charging pile.

[0005] Therefore, it is necessary to provide a dust-proof and heat-dissipating new energy charging pile to solve the above problems. Summary of the invention

[0006] In view of the deficiencies in the prior art, the object of the present invention is to provide a dust-proof and heat-dissipating new energy charging pile.

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a dust-proof and heat-dissipating new energy charging pile, comprising a charging pile shell, a radiator and a charging head, wherein the radiator is arranged inside the charging pile shell, one end of the charging head is arranged on the outer wall of the radiator, and the other end of the charging head is connected to the inside of the charging pile shell, an anti-wear component for reducing the wear of the charging head is arranged at the bottom of the charging pile shell, and a heat dissipation component for assisting the radiator in dissipating heat is arranged inside the charging pile shell.

[0008] Preferably, the anti-wear component includes a sleeve member, which is fixedly connected to the bottom of the charging pile housing, a U-shaped groove is provided at one end of the sleeve member away from the charging pile housing, the internal sliding connection of the U-shaped groove is a limited position bead group, the outer side of the sleeve member is slidingly connected to a resistance block, the outer side of the sleeve member is fixedly connected to a positioning ring, the outer side of the sleeve member is sleeved with a reset spring, and one end of the reset spring is fixedly connected to the positioning ring, and the other end of the reset spring is fixedly connected to the resistance block.

[0009] Preferably, the anti-wear component also includes an annular positioning block, which is fixedly connected to one end of the sleeve member close to the charging pile housing, and the inside of the annular positioning block is slidably connected to an electric telescopic rod, and the end of the electric telescopic rod away from the annular positioning block is fixedly connected to a shift-blocking ring.

[0010] Preferably, the heat dissipation assembly includes a positioning plate, the positioning plate is fixedly connected to the interior of the charging pile housing, a trapezoidal gas gathering groove is provided at the bottom of the positioning plate, and a Tesla block is fixedly connected to the top of the positioning plate.

[0011] Preferably, the heat dissipation assembly includes a fixed block, the fixed block is fixedly connected to the top of the positioning plate, the top of the fixed block is fixedly connected to a distance increasing ring, the inner side of the distance increasing ring is fixedly connected to a cooling tube, the interior of the cooling tube is provided with air inlet holes in a ring-shaped arrangement, one end of the cooling tube is fixedly connected to an air blocking block, and the end of the cooling tube away from the air blocking block is fixedly connected to the interior of the positioning plate.

[0012] Preferably, the sleeve member is sleeved on an end of the charging head away from the charging pile housing, the inner wall of the abutment block is arranged to be inclined, and the limiting bead group is arranged on the inner side of the abutment block.

[0013] Preferably, the electric telescopic rod is electrically connected to a power source used by the device.

[0014] Preferably, the positioning plate is arranged above the radiator, and the trapezoidal gas gathering groove is connected with the Tesla block and the fixed block.

[0015] Preferably, the fixed block is sleeved on the outside of the Tesla block, and the interior of the Tesla block is provided with strip blocks in a herringbone shape.

[0016] Preferably, the air inlet is opened in an inclined shape.

[0017] The dust-proof and heat-dissipating new energy charging pile provided by the present invention has the following beneficial effects compared with the prior art: 1. Through the setting of the anti-wear component, under normal circumstances, the resistance block will cause the limit bead group to squeeze one end of the charging head, thereby fixing the cable of the charging head, reducing the contact area between the cable of the charging head and the charging pile shell to prevent the cable of the charging head from shaking, thereby effectively improving the cable installation stability of the charging head and reducing cable wear. Secondly, the market usually adopts a clamping method for the cable of the charging head, and the clamping block of this method needs to resist the cable of the charging head, which leads to the cable of the charging head often being worn during the movement. Due to the setting of the limit bead group, the spherical surface of the limit bead group is used to fix the cable of the charging head, and the cable of the charging head on the market is often made of rubber. Therefore, the limit bead group can also fix the cable of the charging head by using the spherical surface, and correspondingly reduces the contact area between the fixed parts and the cable of the charging head. The limit bead group uses "points" to fix the charging cable, which is different from the "surface" used for fixing in the prior art, thereby avoiding wear on the cable of the charging head. Secondly, the staff can compress the reset spring toward the positioning ring through the resistance block, so that the inclined part of the resistance block and the limit bead group are on the same horizontal line, so that there is a certain gap between the resistance block and the limit bead group, so that the resistance block releases the restriction on the limit bead group. At this time, the staff can pull the cable of the charging head to charge the vehicle, avoiding the wear of the charging head cable caused by the spring pulling the charging head quickly when the resistance block is not pulled, and avoiding the situation where part of the cable of the charging head is exposed outside the charging pile for a long time due to misoperation; Secondly, when the charging pile is not started, the electric telescopic rod will limit the resistance block through the blocking ring, thereby limiting the cable length of the charging head, thereby reducing the risk of damage by human pulling when the charging head is not in use, and at the same time reducing the frequency of the charging head cable being pulled, thereby increasing the service life of the charging head cable.

[0018] 2. Through the arrangement of the heat dissipation component, the hot air discharged from the radiator will flow into the interior of the heat dissipation tube through the inclined air inlet hole. At the same time, the inclined air inlet hole can better guide the hot air discharged from the radiator to flow into the interior of the heat dissipation tube. Compared with the vertical or horizontal air inlet holes used in the prior art, the inclination angle can prevent the discharged hot air from flowing back to the radiator to a certain extent, ensuring the unidirectionality of the heat dissipation process. At the same time, the inclined air inlet hole can make use of the natural flow trend of the airflow to make the hot air vortex-shaped, and then part of the hot air will flow out from the gap between the air blocking block and the cooling tube in a spiral shape along the wall of the cooling tube, and be discharged into the shell of the charging pile. The remaining hot air then flows in an opposite spiral due to the obstruction of the air blocking block. In this process, the energy loss of the hot air and the convection between the exhausted hot air and the remaining hot air quickly cool down the hot air. Then, the cooled airflow flows back into the charging pile shell through the cooling pipe near the end of the positioning plate, thereby achieving the purpose of cooling, avoiding the damage of the electronic components inside the charging pile caused by excessive temperature of the radiator. At the same time, the auxiliary heat sink effectively absorbs the heat generated during the operation of the charging pile, and the auxiliary radiator is kept within a safe operating temperature range, extending the life of the charging pile shell. Compared with the existing technology on the market that only uses heat sinks for cooling, this design uses the principle of vortex tubes to assist the heat sink of the charging pile to cool down, avoiding the addition of additional equipment. At the same time, this design method does not require additional energy consumption, and only uses spiral flow and convection to consume heat to achieve the purpose of assisting the radiator to dissipate heat. At the same time, it can continuously cool the heat emitted by the heat sink, improve the heat dissipation effect of the radiator during the operation of the charging pile, and at the same time reduce the temperature inside the charging pile, reduce the thermal aging and damage of electronic components, and extend the service life of the charging pile; Among them, the setting of the trapezoidal gas gathering groove and the Tesla block enables the trapezoidal gas gathering groove to preliminarily collect the hot air discharged from the radiator, and the strip blocks arranged in a herringbone pattern inside the Tesla block. In the area formed by the strip blocks and the inner walls of the Tesla block, due to the effect of inertia, the fluid tends to continue moving forward in the curved direction rather than flowing in the opposite direction. This inertial effect enables the hot air to maintain a certain flow direction in the Tesla valve and accelerates the flow of the hot air to a certain extent. Subsequently, the Tesla block is used to accelerate the flow of the collected hot air, so that the hot air can smoothly flow into the cooling pipe through the air inlet, thereby improving the cooling effect of the cooling pipe.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present invention.

[0023] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0024] Implementation example Figures 1 to 11As shown, a dust-proof and heat-dissipating new energy charging pile provided by an embodiment of the present invention includes a charging pile shell 11, a radiator 12 and a charging head 13. The radiator 12 is arranged inside the charging pile shell 11, one end of the charging head 13 is arranged on the outer wall of the radiator 12, and the other end of the charging head 13 is connected to the inside of the charging pile shell 11. An anti-wear component for reducing the wear of the charging head 13 is arranged at the bottom of the charging pile shell 11, and a heat dissipation component for assisting the radiator 12 in dissipating heat is arranged inside the charging pile shell 11.

[0025] The anti-wear component includes a sleeve member 21, which is fixedly connected to the bottom of the charging pile housing 11. A U-shaped groove 22 is provided at one end of the sleeve member 21 away from the charging pile housing 11. The internal sliding connection of the U-shaped groove 22 is a limited position bead group 23. The outer side of the sleeve member 21 is slidingly connected to a resistance block 24. A positioning ring 25 is fixedly connected to the outer side of the sleeve member 21. A reset spring 26 is sleeved on the outer side of the sleeve member 21, and one end of the reset spring 26 is fixedly connected to the positioning ring 25, and the other end of the reset spring 26 is fixedly connected to the resistance block 24.

[0026] The anti-wear component also includes an annular positioning block 27, which is fixedly connected to one end of the sleeve member 21 close to the charging pile housing 11, and an electric telescopic rod 28 is slidably connected inside the annular positioning block 27, and an end of the electric telescopic rod 28 away from the annular positioning block 27 is fixedly connected to a shift-blocking ring 29.

[0027] The sleeve member 21 is sleeved on one end of the charging head 13 away from the charging pile housing 11, so that when the staff pulls the charging head 13, the charging head 13 needs to contact the sleeve member 21, and the inner wall of the contact block 24 is set to be inclined, so that there is a partial gap between the contact block 24 and the limiting bead group 23, and the limiting bead group 23 is set on the inner side of the contact block 24, so that the contact block 24 can limit the position of the limiting bead group 23.

[0028] The electric telescopic rod 28 is electrically connected to the power source used by the device, so that when the charging pile is not in use, the electric telescopic rod 28 limits the position of the resistance block 24 through the blocking ring 29.

[0029] The heat dissipation assembly includes a positioning plate 31 , which is fixedly connected to the interior of the charging pile housing 11 , a trapezoidal gas gathering groove 32 is provided at the bottom of the positioning plate 31 , and a Tesla block 33 is fixedly connected to the top of the positioning plate 31 .

[0030] The heat dissipation assembly includes a fixed block 34, which is fixedly connected to the top of the positioning plate 31, and a distance-increasing ring 35 is fixedly connected to the top of the fixed block 34. A cooling tube 36 is fixedly connected to the inner side of the distance-increasing ring 35. The interior of the cooling tube 36 is provided with air inlet holes 37 in a ring-shaped pattern. One end of the cooling tube 36 is fixedly connected to an air blocking block 38, and the end of the cooling tube 36 away from the air blocking block 38 is fixedly connected to the interior of the positioning plate 31.

[0031] The positioning plate 31 is arranged above the radiator 12 so that the hot air emitted by the radiator 12 can be initially collected by the trapezoidal gas collecting groove 32. The trapezoidal gas collecting groove 32 is connected with the Tesla block 33 and the fixed block 34 so that the hot air collected by the trapezoidal gas collecting groove 32 can flow into the interior of the fixed block 34.

[0032] The fixed block 34 is sleeved on the outside of the Tesla block 33 so that the hot air inside the Tesla block 33 can flow into the fixed block 34. The interior of the Tesla block 33 is provided with strip blocks in a herringbone shape. The area formed by the strip blocks inside the Tesla block 33 and the inner wall of the Tesla block 33, due to inertia, the fluid tends to continue to move forward in the curved direction rather than flow in the opposite direction. This inertial effect enables the hot air to maintain a certain flow direction in the Tesla valve and accelerates the flow of the hot air to a certain extent.

[0033] The air inlet 37 is opened in an inclined shape so that the air flowing through the air inlet 37 will be in a spiral shape.

[0034] Working principle: In the initial state, the limit bead group 23 is in conflict with the abutment block 24, the return spring 26 is not compressed, the blocking ring 29 is in conflict with the abutment block 24, and the electric telescopic rod 28 is in an extended state.

[0035] When the staff needs to use the charging pile during work, the staff first needs to scan the code of the charging pile to start it, and then the staff needs to pull the charging head 13 to connect the charging head 13 with the vehicle; At this time, the staff has an electrical connection between the electric telescopic rod 28 and the power supply used by the equipment. When the charging pile is started, the electric telescopic rod 28 is powered on and retracts toward the inside of the annular positioning block 27. Then, the electric telescopic rod 28 drives the blocking ring 29 to move synchronously toward the annular positioning block 27, so that the annular positioning block 27 releases the restriction on the position of the resistance block 24. At this time, the staff member holds the resistance block 24 and moves it in the direction of the blocking ring 29, and then the resistance block 24 will gradually compress the reset spring 26 in the direction of the positioning ring 25. Because the inner wall of the resistance block 24 is set to an inclined shape, the resistance block 24 cannot limit the position of the limit bead group 23 at this time. At this time, the staff can pull the charging head 13 away from the charging pile housing 11. At this time, the cable of the charging head 13 will resist the limit bead group 23 and slide along the inside of the U-shaped groove 22. Therefore, the limit bead group 23 is not restricted by the resistance block 24 at this time, thereby achieving the purpose of normal pulling of the charging head 13. In this process, due to the setting of the limit bead group 23, the ball surface of the limit bead group 23 is used to fix the cable of the charging head 13, and the cable of the charging head 13 on the market is often made of rubber, thereby avoiding wear on the cable of the charging head 13. At the same time, after the staff pulls the cable of the charging head 13, the return spring 26 will elastically stretch and push the resistance block 24 to move away from the positioning ring 25, so that the resistance block 24 will resist the limit bead group 23 again to restrict the cable of the charging head 13, and at the same time avoid the situation that when the staff does not pull the resistance block 24, the spring in the prior art quickly pulls the cable of the charging head 13 to cause wear. When the charging pile is not started, the electric telescopic rod 28 will limit the resistance block 24 through the blocking ring 29, thereby limiting the length of the cable of the charging head 13, thereby reducing the risk of damage by human pulling when the charging head 13 is not in use, and reducing the frequency of the cable of the charging head 13 being pulled, thereby increasing the service life of the cable of the charging head 13, and avoiding the situation that part of the cable of the charging head 13 is exposed outside the charging pile for a long time due to misoperation; During the operation of the charging pile, it is necessary to convert AC power into DC power or adjust parameters such as voltage and current. Energy loss will inevitably occur during this power conversion process, and most of this lost energy will be dissipated in the form of heat. Since a large amount of heat is generated during the operation of the charging pile, the radiator 12 is often in a load state. The hot air generated during the radiator 12 process will naturally rise, and the trapezoidal gas collection groove 32 will collect the hot air and make it gradually flow into the bottom of the Tesla block 33. Because the interior of the Tesla block 33 is in a herringbone shape with strip blocks, the hot air passing through the Tesla block 33 is accelerated. At the same time, the trapezoidal gas collection groove 32 is connected to the Tesla block 33 and the fixed block 34. At this time, the hot air collected by the trapezoidal gas collection groove 32 gradually flows into the interior of the fixed block 34 through the Tesla block 33; The hot air flowing into the top of the fixed block 34 will flow in a ring shape around the cooling tube 36 due to the setting of the distance increasing ring 35. At the same time, because the air inlet 37 is opened in an inclined shape, the air flowing into the cooling tube 36 through the air inlet 37 will flow in a spiral shape. At this time, the hot air flow will flow out from the gap between the air blocking block 38 and the cooling tube 36 in a spiral shape along the wall of the cooling tube 36 and be discharged from the inside of the charging pile housing 11. The remaining hot air then flows in an opposite spiral manner due to the obstruction of the air blocking block 38. In this process, the hot air loses energy and the exhaust hot air forms convection with the remaining hot air, thereby rapidly cooling the hot air. The cooled air then flows back into the charging pile housing 11 through the cooling pipe 36 near the end of the positioning plate 31, thereby achieving the purpose of cooling. In the above process, the load state of the radiator 12 is reduced, and the damage to the internal electronic components of the charging pile caused by excessively high temperature is avoided. At the same time, the auxiliary heat sink effectively absorbs the heat generated during the operation of the charging pile, and the auxiliary radiator 12 is kept within a safe operating temperature range, thereby extending the life of the charging pile housing 11; At the same time, compared with the existing technologies on the market, this design uses the principle of vortex tubes to assist in cooling the heat sink of the charging pile, avoiding the addition of additional equipment. At the same time, this design does not require additional energy consumption, and only uses spiral flow and convection to consume heat to achieve the purpose of assisting the radiator 12 in dissipating heat, thereby improving the heat dissipation effect of the radiator 12 during the operation of the charging pile, while reducing the temperature inside the charging pile, reducing thermal aging and damage of electronic components, and extending the service life of the charging pile.
