Description

Technical Field

[0001] This utility model relates to the field of electric vehicle charging pile technology, and in particular to an electric vehicle charging pile. Background Technology

[0002] Electric vehicle charging stations are devices that provide power to electric vehicles. They connect the power grid to the electric vehicle and are an important part of the energy supply for electric vehicles. Simply put, just like a mobile phone charger, charging stations "charge" electric vehicles so that they can continue to drive.

[0003] Most charging piles use air cooling to dissipate the heat generated internally during charging. For example, the prior art Chinese patent announcement number "CN217421010U" discloses a heat dissipation door panel, including a louvered door assembly, including a plurality of rotatable louvers arranged sequentially along a first direction, and at least one connecting strip connected to the same side of the plurality of rotatable louvers; a flipping control mechanism, including at least a motor and a push rod mechanism; the push rod mechanism is mechanically connected to the motor and at least one rotatable louver respectively; the motor drives the push rod mechanism to move; the push rod mechanism drives the rotatable louvers to flip; a controller, including a motor control signal output terminal, is electrically connected to the control terminal of the motor. The controller is used to control the operating state of the motor, so that when heat dissipation is needed, the push rod mechanism can drive the rotatable louvers to flip in the opening direction under the drive of the motor to open the louvered door to the maximum extent to improve heat dissipation efficiency, and when heat dissipation is not needed, it can drive the rotatable louvers to flip in the closing direction to effectively prevent dust.

[0004] In actual operation, the heat dissipation door panel is equipped with a louvered door assembly. The louvered door assembly dissipates heat by opening and closing under the control of the motor. However, considering that the motor and louvered door assembly are not easy to clean and maintain after long-term use, and that long-term cleaning and maintenance will affect the normal heat dissipation of the equipment, its practicality is poor. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where the heat dissipation components are difficult to clean and maintain, and to propose an electric vehicle charging station.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The design includes a charging pile housing, with a heat dissipation vent communicating with the interior on the side of the charging pile housing, and a heat dissipation component located on the side, the heat dissipation component including a heat dissipation cover, a dust baffle and a filter screen;

[0008] The heat dissipation shroud is installed over the heat dissipation opening, and the dust baffle is installed inside the heat dissipation shroud through a stop structure. The dust baffle is used to cover the first heat dissipation groove inside the heat dissipation shroud, and the filter screen is also provided inside the heat dissipation shroud.

[0009] Furthermore, the heat dissipation cover has a circular structure, and a stepped groove is provided on the side near the outer shell of the charging pile. The midpoint of the stepped groove extends outward to form a receiving groove, and two sets of the first heat dissipation grooves are symmetrically distributed in a circular structure within the receiving groove.

[0010] The two sets of first heat dissipation slots are arranged radially, and the slot opening heights of adjacent sets of first heat dissipation slots are staggered.

[0011] Furthermore, the dust baffle plate has a second heat dissipation groove with the same structure as the first heat dissipation groove on its end face. Rotating the dust baffle plate allows the second heat dissipation groove to block or connect with the first heat dissipation groove.

[0012] Furthermore, the stop structure includes a stop portion, and at least one pair of the stop portions are provided at the midpoint of the receiving groove, and the stop portion has an L-shaped structure;

[0013] The dust baffle is rotatably connected in the receiving groove, and the protruding part at the end of the stop part slides through the central through hole of the dust baffle to stop the dust baffle.

[0014] Furthermore, the dust baffle has a protruding post on its side, which is slidably connected in one of the first heat dissipation slots. Deformation parts are provided at both ends of the first heat dissipation slot, and the protruding post is fixed to the heat dissipation cover through the deformation parts.

[0015] Furthermore, the diameter of the filter screen is adapted to the stepped groove, and both sides of the filter screen abut against the stepped groove and the charging pile housing, respectively.

[0016] The electric vehicle charging pile proposed in this utility model has the following advantages: The charging pile casing is equipped with a cooling fan, a heat dissipation cover, and a filter screen at the heat dissipation vent. The cooling fan guides and exhausts the high-temperature air inside the charging pile, dissipating heat through air exchange. During this process, the heat dissipation cover and the dust baffle are connected by a stop structure to facilitate heat dissipation between the first and second heat dissipation slots, working in conjunction with the cooling fan and filter screen. When the charging pile is not in use, rotating the dust baffle causes the first and second heat dissipation slots to be staggered, achieving mutual shielding and closure to prevent external dust from entering the charging pile through the heat dissipation slots when it is idle. Furthermore, after removing the heat dissipation cover, the dust baffle and filter screen can be cleaned and maintained. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-6 The charging pile includes a charging pile housing 1, a heat dissipation vent communicating with the interior is provided on the side of the charging pile housing 1, and a heat dissipation component 2 is also provided on the side, the heat dissipation component 2 includes a heat dissipation cover 21, a dust baffle 22 and a filter screen 23.

[0026] The heat sink 21 is installed over the heat dissipation opening, and the dust baffle 22 is installed inside the heat sink 21 through the stop structure 3. The dust baffle 22 is used to cover the first heat dissipation groove 211 inside the heat sink 21. The filter screen 23 is also provided inside the heat sink 21.

[0027] In some embodiments, a cooling fan is also fixedly connected to the inner bottom of the heat dissipation vent. The cooling fan is electrically connected to the power module and control module inside the charging pile housing 1. The cooling fan, together with the filter screen 23, guides the high-temperature air inside the charging pile to be discharged, and dissipates heat through the exchange of internal and external air.

[0028] Furthermore, the dust baffle 22 is rotatably connected and fixed to the heat sink 21 through the stop structure 3. When the charging pile is in use, the operator manually rotates the dust baffle 22 to make the second heat sink 221 connect with the first heat sink 211. Similarly, when the charging pile is idle, the second heat sink 221 and the first heat sink 211 are closed to prevent external dust from entering the charging pile along the heat sink.

[0029] It is worth mentioning that at least one pair of support feet are distributed around the heat sink 21. The support feet fit into the charging pile housing 1 and can be fixed between them by locking bolts. Specifically, a sealing gasket can be provided between the heat sink 21 and the outer wall of the charging pile housing 1 to further improve the sealing performance.

[0030] Furthermore, the heat dissipation cover 21 has a circular structure, and a stepped groove 212 is provided on the side near the charging pile shell 1. The midpoint of the stepped groove 212 extends outward to form a receiving groove 213. Two sets of the first heat dissipation grooves 211 are symmetrically distributed in a circular structure within the receiving groove 213.

[0031] The two sets of first heat dissipation slots 211 are arranged radially, and the slot opening heights of adjacent sets of first heat dissipation slots 211 are staggered.

[0032] Furthermore, the dust baffle 22 has a second heat dissipation groove 221 with the same structure as the first heat dissipation groove 211 on its end face. Rotating the dust baffle 22 allows the second heat dissipation groove 221 to block or connect with the first heat dissipation groove 211.

[0033] It should be added that the operation method of rotating the heat sink 21 and the dust baffle 22 to make the second heat sink 221 and the first heat sink 211 mutually shield or connect is similar to the actual product air freshener box lid structure. The specific principle is that the heat sink 21 and the dust baffle 22 achieve mutual connection or shielding through the staggered heat sink slots.

[0034] It should be added that the spacing between the second heat dissipation slots 221 can be slightly smaller than that between the first heat dissipation slots 211, so as to prevent the gaps from not fitting tightly when the first and second heat dissipation slots cover each other. In addition, the heat dissipation cover 21 and the dust baffle 22 are fitted with a gap through the stop part 31 to further prevent dust from entering.

[0035] More specifically, the stop structure 3 includes a stop portion 31, and at least one pair of the stop portions 31 are provided at the midpoint of the receiving groove 213. The stop portions 31 have an L-shaped structure.

[0036] The dust baffle 22 is rotatably connected in the receiving groove 213, and the protruding part at the end of the stop part 31 slides through the central through hole of the dust baffle 22 to stop the dust baffle 22.

[0037] In this embodiment, the stop part 31 and the heat sink 21 are integrally formed, and both are preferably made of materials with deformation capabilities such as rubber and plastic. The protruding part at the end of the stop part 31 abuts against the dust baffle 22 and deforms, and then passes through the central through hole of the dust baffle 22, so that the dust baffle 22 can be limited in the receiving groove 213 by the stop action.

[0038] Specifically, the receiving groove 213 is used to allow the dust baffle 22 to rotate, and the stepped groove 212 is set so that the filter screen 23 and the dust baffle 22 are spaced apart to avoid mutual contact.

[0039] In general, the dust baffle 22 has a protruding post 32 on its side, which is slidably connected in one of the first heat dissipation slots 211. Deformation parts 33 are provided on both ends of the first heat dissipation slot 211, and the protruding post 32 is fixed to the heat dissipation cover 21 through the deformation parts 33.

[0040] In this embodiment, as Figure 3 and Figure 4 As shown, the deformation part 33 includes a deformation groove, the first heat dissipation groove 211 is provided with a pair of corresponding deformation grooves at both ends, and a protrusion structure is provided at the movable end of the deformation groove, with the protrusion structures on both sides arranged opposite to each other.

[0041] Specifically, the protruding post 32 slides along the first heat dissipation groove 211. When its outer wall comes into contact with the protruding structures on both sides, the protruding structures are subjected to force and deform under the action of the deformation groove to avoid the protruding post 32. After the protruding structure recovers its deformation, it stops the protruding post 32, thereby fixing the position of the heat dissipation cover 21 and the dust baffle 22.

[0042] Finally, the diameter of the filter screen 23 is adapted to the stepped groove 212, and the two sides of the filter screen 23 abut against the stepped groove 212 and the charging pile shell 1, respectively.

[0043] Specifically, the filter 23 is designed to filter out dust from the outside environment during the heat dissipation process.

[0044] Working method: When the operator uses the charging pile to charge, the dust baffle 22 is driven to rotate manually by the protrusion 32. After the protrusion 32 is detached from the fixing of the deformation part 33 on one side, it can slide into the deformation part 33 on the other side for fixing. In this way, the dust baffle 22 can be fixed. At this time, the first heat dissipation groove 211 and the second heat dissipation groove 221 are connected to each other, and heat dissipation is carried out through the exchange of internal and external cavities under the action of the cooling fan and the filter screen 23.

[0045] After charging is complete, the operator rotates the dust baffle 22 in the opposite manner. Once the dust baffle 22 is fixed, the first heat dissipation groove 211 and the second heat dissipation groove 221 close together to prevent external dust from entering the interior when the charging pile is idle.

[0046] Finally, the dust baffle 22 and filter screen 23 can be replaced and maintained by removing the heat sink 21.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
