Description

Technical Field

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

[0002] A new energy charging pile is a device that provides electrical energy supply for new energy vehicles (such as pure electric vehicles, plug-in hybrid vehicles, etc.). Its main components include: a charging gun, a charging cable, a control system, and a display screen. At the same time, the new energy charging pile provides a convenient charging facility for new energy vehicles, solves the worry about the cruising range of new energy vehicles, and promotes the popularization and promotion of new energy vehicles.

[0003] For example, a Chinese invention patent with the authorization announcement number CN111267657B provides a charging pile that uses a spiral spring to store the cable of the charging gun, avoiding the charging gun and cable being exposed outside for a long time, reducing the erosion of rain and sunlight on the charging gun and cable, and at the same time reducing the risk of being damaged by humans. At the same time, in the prior art, a support seat and a metal hoop are usually provided at the wire outlet of the outer 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 deformed by the extrusion of the cable and loses its binding force, resulting in the cable becoming loose and the installation stability being poor; when the loose cable shakes, it is easily cut by the metal hoop and damaged, resulting in a shortened service life; and the long-term friction will gradually wear the insulating layer of the cable, reducing the insulation performance of the cable, which will cause safety problems such as electric leakage and short circuit, endangering users and vehicles, and the long-term friction will also damage the conductor inside the cable, resulting in an increase in resistance. After the resistance increases, more heat will be generated during the charging process, reducing the charging efficiency, and at the same time affecting the life of the battery. In addition, the friction between the cable and the charging pile will also cause wear and scratches on the outer shell of the charging pile, affecting the appearance and service life of the charging pile. Especially in the outdoor environment, the worn outer shell is more vulnerable 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 devices, such as an air-conditioning system or a liquid cooling device. This not only increases the cost and complexity of the device, but also the additional heat dissipation devices usually consume additional energy. At the same time, due to the poor heat dissipation effect, the internal temperature of the charging piles on the market is likely to increase, which will accelerate the thermal aging of electronic components. The long-term high-temperature environment will cause the performance of electronic components to decline, the service life to be shortened, and even malfunction, 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:

[0018] 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.

[0019] 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;

[0020] 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.

[0021] 2. Through the setting of the heat dissipation component, the hot air discharged by the radiator will flow into the interior of the heat dissipation cylinder through the inclined air inlet holes. At the same time, the inclined air inlet holes can better guide the hot air discharged by the radiator into the interior of the heat dissipation cylinder. Compared with the vertical or horizontal air inlet holes used in the prior art, the inclined 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 holes can make the hot air form a vortex shape by utilizing the natural flow trend of the air flow. Subsequently, part of the hot air flow flows out of the gap between the air blocking block and the cooling pipe in a spiral shape along the wall of the cooling pipe and is discharged from the interior of the charging pile housing. Then, the remaining hot air flows in the opposite spiral flow mode due to the blockage of the air blocking block. During this process, due to the energy loss of the hot air and the convection formed by the discharged hot air and the remaining hot air, the part of the hot air is quickly cooled. Subsequently, the cooled air flow of this part flows back into the interior of the charging pile housing through the end of the cooling pipe close to the positioning plate, thereby achieving the purpose of cooling, avoiding the damage to the internal electronic components of the charging pile caused by the excessive temperature generated by the radiator, and at the same time, the auxiliary heat dissipation plate effectively absorbs the heat generated during the operation of the charging pile, assisting the radiator to maintain within a safe operating temperature range and extending the service life of the charging pile housing;

[0022] Compared with the prior art that only uses heat dissipation blocks for cooling in the market, this design uses the principle of the vortex tube to assist the heat dissipation block of the charging pile for cooling, avoiding the addition of extra 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 for heat dissipation. At the same time, it can continuously cool the heat dissipated by the heat dissipation block, improving the heat dissipation effect of the radiator during the operation of the charging pile, reducing the temperature inside the charging pile, reducing the thermal aging and damage of electronic components, and extending the service life of the charging pile;

[0023] Among them, the setting of the trapezoidal air gathering groove and the Tesla block enables the trapezoidal air gathering groove to initially collect the hot air discharged by the radiator. In the area formed by the strip-shaped blocks arranged in a herringbone pattern inside the Tesla block and the inner wall of the Tesla block, due to the inertia effect, the fluid tends to continue to move forward along the curved direction rather than reverse flow. 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, enabling the hot air to smoothly flow into the interior of the cooling pipe through the air inlet holes, improving the cooling effect of the cooling pipe.

[0038] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0039] In the description of the present invention, the orientation or positional relationship indicated by terms such as "center", "lateral", "upper", "lower", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0040] The following describes the specific implementation of the present invention in detail in conjunction with specific embodiments.

[0041] As shown in the embodiment Figures 1 to 11 A dust-proof and heat-dissipating new energy charging pile provided by an embodiment of the present invention includes a charging pile housing 11, a radiator 12 and a charging head 13. The radiator 12 is arranged inside the charging pile housing 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 housing 11. An anti-wear component for reducing the wear of the charging head 13 is arranged at the bottom of the charging pile housing 11, and a heat-dissipating component for assisting the radiator 12 in heat dissipation is arranged inside the charging pile housing 11.

[0042] The anti-wear component includes a sleeve member 21. The sleeve member 21 is fixedly connected to the bottom of the charging pile housing 11. A U-shaped groove 22 is opened at one end of the sleeve member 21 away from the charging pile housing 11. A limiting bead group 23 is slidably connected inside the U-shaped groove 22. A contact block 24 is slidably connected to the outside of the sleeve member 21. A positioning ring 25 is fixedly connected to the outside of the sleeve member 21. A return spring 26 is sleeved on the outside of the sleeve member 21, and one end of the return spring 26 is fixedly connected to the positioning ring 25, and the other end of the return spring 26 is fixedly connected to the contact block 24.

[0043] The anti-wear component further includes an annular positioning block 27. The annular positioning block 27 is fixedly connected to one end of the sleeve member 21 close to the charging pile housing 11. An electric telescopic rod 28 is slidably connected inside the annular positioning block 27. One end of the electric telescopic rod 28 away from the annular positioning block 27 is fixedly connected to a displacement blocking ring 29.

[0044] The sleeve member 21 is sleeved on one end of the charging head 13 away from the charging pile housing 11. When a staff member pulls the charging head 13, the charging head 13 needs to contact the sleeve member 21. 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 arranged inside the contact block 24, so that the contact block 24 can limit the position of the limiting bead group 23.

[0045] The electric telescopic rod 28 has an electrical connection relationship with the device power supply. When the charging pile is not in use, the electric telescopic rod 28 limits the position of the contact block 24 through the displacement blocking ring 29.

[0046] The heat dissipation component includes a positioning plate 31, the positioning plate 31 is fixedly connected to the inside of the charging pile housing 11, a trapezoidal air-gathering groove 32 is formed at the bottom of the positioning plate 31, and a Tesla block 33 is fixedly connected to the top of the positioning plate 31.

[0047] The heat dissipation component includes a fixing block 34, the fixing block 34 is fixedly connected to the top of the positioning plate 31, an extension ring 35 is fixedly connected to the top of the fixing block 34, a cooling pipe 36 is fixedly connected to the inside of the extension ring 35, air inlet holes 37 are annularly distributed inside the cooling pipe 36, a gas-blocking block 38 is fixedly connected to one end of the cooling pipe 36, and the other end of the cooling pipe 36 away from the gas-blocking block 38 is fixedly communicated with the inside of the positioning plate 31.

[0048] The positioning plate 31 is arranged above the radiator 12, so that the hot air dissipated by the radiator 12 can be initially collected by the trapezoidal air-gathering groove 32. The trapezoidal air-gathering groove 32 is communicated with the Tesla block 33 and the fixing block 34, so that the hot air collected by the trapezoidal air-gathering groove 32 can flow into the inside of the fixing block 34.

[0049] The fixing block 34 is sleeved outside the Tesla block 33, so that the hot air inside the Tesla block 33 can flow into the inside of the fixing block 34. Strip-shaped blocks are arranged in a herringbone shape inside the Tesla block 33. For the area formed by the strip-shaped blocks inside the Tesla block 33 and the inner wall of the Tesla block 33, due to the inertia effect, the fluid tends to continue to move along the curved direction rather than flow in the reverse direction. This inertia 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.

[0050] The air inlet holes 37 are inclined, so that the air flowing through the air inlet holes 37 will be in a spiral shape.

[0051] Working principle: In the initial state, the limit bead group 23 abuts against the abutting block 24, the reset spring 26 is not compressed, the anti-displacement ring 29 abuts against the abutting block 24, and the electric telescopic rod 28 is in the extended state.

[0052] When working, when the staff needs to use the charging pile, the staff first needs to scan the code to start the charging pile, and then the staff needs to pull out the charging head 13 to connect the charging head 13 with the vehicle.

[0053] At this time, since there is an electrical connection relationship between the electric telescopic rod 28 and the power supply used by the device, when the charging pile is started, after the electric telescopic rod 28 is powered on, it contracts towards the inside of the annular positioning block 27. Then the electric telescopic rod 28 drives the anti-displacement ring 29 to move towards the annular positioning block 27 synchronously, so that the annular positioning block 27 releases the restriction on the position of the abutting block 24.

[0054] 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.

[0055] 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;

[0056] 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;

[0057] The hot air flowing into the top of the fixed block 34 will, due to the setting of the spacer ring 35, cause the hot air in this part to flow in a circular manner around the cooling pipe 36. At the same time, since the air inlet holes 37 are inclined, the air flowing into the cooling pipe 36 through the air inlet holes 37 will flow in a spiral manner. At this time, the divided hot air flows out from the gap between the air blocking block 38 and the cooling pipe 36 in a spiral shape along the wall of the cooling pipe 36 and is discharged from the inside of the charging pile housing 11;

[0058] Subsequently, the remaining hot air, due to the blockage of the air blocking block 38, flows in the opposite spiral flow mode. During this process, due to the energy loss of the hot air and the convection formed by the discharged hot air and the remaining hot air, the hot air in this part is quickly cooled. Subsequently, the cooled air in this part flows back into the inside of the charging pile housing 11 through the end of the cooling pipe 36 close to the positioning plate 31, thereby achieving the purpose of cooling;

[0059] In the above process, the load state of the radiator 12 is reduced, avoiding the damage to the internal electronic components of the charging pile caused by excessive temperature. At the same time, the auxiliary heat dissipation plate effectively absorbs the heat generated during the operation of the charging pile, assisting the radiator 12 to maintain within a safe operating temperature range and extending the service life of the charging pile housing 11;

[0060] At the same time, compared with the existing technologies in the market, this design uses the principle of the vortex tube to assist in cooling the heat dissipation block of the charging pile, avoiding the addition of extra 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 12 in heat dissipation, improving the heat dissipation effect of the radiator 12 during the operation of the charging pile, reducing the temperature inside the charging pile, reducing the thermal aging and damage of electronic components, and extending the service life of the charging pile.
