Description

Technical Field

[0001] This utility model belongs to the field of charging pile technology, and in particular relates to a protective shell based on a charging pile. Background Technology

[0002] Charging stations, also known as electric vehicle charging stations or electric vehicle power supply equipment, are devices that provide electrical energy to electric vehicles, enabling them to store enough electricity to support their operation. For convenience, some car owners typically install private charging stations on the walls of their garages, and protective casings are often installed around these stations for added protection.

[0003] Currently, the protective shells of common charging piles on the market usually lack quick-disassembly structures, resulting in inconvenient installation, disassembly, and maintenance. In addition, charging piles generate a lot of heat during operation, and the heat in the part of the charging pile that is in close contact with the shell is difficult to dissipate quickly. The accumulation of heat will affect the lifespan of the internal components of the charging pile, leading to accelerated aging and even causing safety hazards such as fire.

[0004] Therefore, there is an urgent need to improve the protective shell of existing charging piles and provide a protective shell based on charging piles that is quick and easy to disassemble and repair, and has good heat conduction. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the existing technology by providing a charging pile protective shell that is reasonably designed, simple in structure, quick and convenient to disassemble and repair, and has good thermal conductivity, thereby solving the problems existing in the prior art.

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

[0007] A protective housing for a charging pile includes a charging pile body, an outer shell covering the outer side of the charging pile body, a door mounted on the front end of the outer shell via a hinge, a door lock mounted on the door, a heat-conducting component mounted on the bottom rear end of the outer shell, a base plate detachably connected to the rear of the outer shell, a positioning component mounted inside the top end of the base plate, a through-flow air supply cavity opened inside the bottom end of the base plate, and two electric fans symmetrically mounted on the outer wall of the bottom front end of the base plate via bolts, with the suction end of the electric fans located inside the air supply cavity.

[0008] Preferably, the heat-conducting component includes a heat-conducting plate, an air-guiding plate, and heat dissipation fins. The heat-conducting plate is embedded and fixed on the inner wall of the bottom rear end of the outer casing. The charging pile body is fixedly installed on the front end face of the heat-conducting plate. An air-guiding plate is fixedly connected to the outer wall of the rear end of the heat-conducting plate. Several heat dissipation fins are arranged at equal intervals along the length direction of the air-guiding plate.

[0009] Preferably, one end of each of the heat dissipation fins passes through the air intake plate and is fixedly connected to the heat conduction plate.

[0010] Preferably, the rear end face of the air-expelling plate is inclined.

[0011] Preferably, the two fans are located behind the middle of the heat dissipation fins.

[0012] Preferably, the positioning assembly includes a horizontal bar, a first slider, a vertical bar, a second slider, a spring, a connecting rod, and a disc. The two horizontal bars are respectively fixed in through slots opened on the left and right sides of the top of the substrate. The first slider is slidably sleeved on the outer side of each of the two horizontal bars. The front end of the first slider is fixed with a disc. The top of the substrate is fixed inside the vertical bar. The second slider is slidably sleeved on the outer side of the vertical bar. The bottom end of the second slider is fixedly connected to the substrate with a spring. The left and right sides of the second slider are hinged to the two first sliders. The two first sliders and the second slider are linked together.

[0013] Preferably, the top rear interior of the outer casing has two first positioning grooves and one second positioning groove. The two first positioning grooves are arranged symmetrically about the second positioning groove. The first positioning groove includes a circular hole and a horizontal straight section, and the second positioning groove has a vertical structure.

[0014] Preferably, the width of the first slider is equal to the width of the horizontal straight portion of the first positioning groove, the diameter of the circular hole portion of the first positioning groove is equal to the diameter of the disk, and the front end of the second slider is provided with a vertically downward extension portion, which is engaged and connected to the outer shell through the second positioning groove.

[0015] Preferably, the bottom end of the extension of the second slider is internally threaded with a positioning bolt, and the inner wall of the outer shell is provided with a positioning hole that matches the positioning bolt, and the positioning hole is located directly below the second positioning groove.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In this invention, the positioning bolt is rotated off. At this time, the second slider can be lifted and reset by the spring along the vertical rod. The two connecting rods can push the two first sliders to drive the two discs to slide synchronously along the horizontal rod in a direction away from each other until the discs move to the circular hole of the first positioning groove. At this time, the outer shell can be pulled forward directly, which makes it easy to disassemble the outer shell from the base plate. The disassembly and assembly are quick, easy to maintain, and easy to operate.

[0018] When the charging pile is in operation, the heat generated can be transferred to multiple equidistant heat dissipation fins through the heat conduction plate. At this time, the fan can be turned on to draw in the outside cold air through the air delivery cavity and blow it out towards the outer shell, which facilitates air cooling of multiple heat dissipation fins, accelerates heat loss and dissipation, and can achieve a good and efficient heat dissipation effect. This can improve the safety of the charging pile in operation and extend its service life. In addition, the air guide plate with an inclined surface at the rear end can easily guide the air blown by the fan downwards to avoid air convection, facilitate the circulation of cold air, and facilitate the rapid removal of heat.

Two fans 11 are symmetrically installed on the outer wall at the front of the bottom end of the base plate 8 via bolts. The suction end of the fan 11 is located inside the air supply cavity 10.

[0030] As a preferred embodiment, based on the above structure, two first positioning grooves 4 and one second positioning groove 5 are further provided inside the rear top of the outer shell 1. The two first positioning grooves 4 are arranged symmetrically about the second positioning groove 5. The first positioning groove 4 includes a circular hole and a horizontal straight section, and the second positioning groove 5 has a vertical structure.

[0031] In this embodiment, the opening of the first positioning groove 4 and the second positioning groove 5 facilitates quick assembly and disassembly between the substrate 8 and the outer shell 1 through the positioning component 9.

[0032] As a preferred embodiment, based on the above structure, the heat-conducting component 7 preferably includes a heat-conducting plate 71, an air-guiding plate 72, and heat dissipation fins 73. The heat-conducting plate 71 is embedded and fixed on the inner wall of the bottom rear end of the outer casing 1. The charging pile body 12 is fixedly installed on the front end face of the heat-conducting plate 71. The air-guiding plate 72 is fixedly connected to the outer wall of the rear end of the heat-conducting plate 71. A plurality of heat dissipation fins 73 are arranged at equal intervals along the length direction of the air-guiding plate 72.

[0033] As a preferred embodiment, based on the above structure, preferably, one end of each of the plurality of heat dissipation fins 73 passes through the air guide plate 72 and is fixedly connected to the heat conduction plate 71, the rear end face of the air guide plate 72 is inclined, and the two electric fans 11 are located behind the middle of the heat dissipation fins 73.

[0034] In this embodiment, the heat generated by the charging pile body 12 during operation is quickly dissipated through the heat-conducting plate 71 and several equidistant heat dissipation fins 73, thereby achieving heat dissipation.

[0035] In a preferred embodiment, based on the above structure, the positioning component 9 preferably includes a horizontal bar 91, a first slider 92, a vertical bar 93, a second slider 94, a spring 95, a connecting rod 96, and a disc 97. The two horizontal bars 91 are respectively fixed in the through slots opened on the left and right sides of the top of the substrate 8. The first slider 92 is slidably sleeved on the outer side of the two horizontal bars 91. The disc 97 is fixed at the front end of the first slider 92. The vertical bar 93 is fixed inside the top of the substrate 8. The second slider 94 is slidably sleeved on the outer side of the vertical bar 93. The bottom end face of the second slider 94 is fixedly connected to the substrate 8 with a spring 95. The left and right sides of the second slider 94 are hinged to the two first sliders 92. The two first sliders 92 and the second slider 94 are linked together.

[0036] As a preferred embodiment, based on the above structure, preferably, the width of the first slider 92 is equal to the width of the horizontal straight portion of the first positioning groove 4, the diameter of the circular hole portion of the first positioning groove 4 is equal to the diameter of the disk 97, and the front end of the second slider 94 is provided with a vertically downward extension portion, which is engaged and connected to the outer shell 1 through the second positioning groove 5.

[0037] In this embodiment, the second slider 94 is pushed downward to engage with the outer shell 1 through the second positioning groove 5. During this process, the connecting rod 96 can pull the two first sliders 92 to slide horizontally and move closer to each other, so that the two discs 97 can engage with the outer shell 1 through the first positioning groove 4, which facilitates the quick installation of the outer shell 1. Similarly, it also facilitates the quick disassembly of the outer shell 1.

[0038] As a preferred embodiment, based on the above structure, the bottom end of the front extension of the second slider 94 is further threaded with a positioning bolt 98, and a positioning hole 6 adapted to the positioning bolt 98 is provided on the inner wall of the outer shell 1. The positioning hole 6 is located directly below the second positioning groove 5.

[0039] In this embodiment, by tightening the positioning bolt 98 and inserting one end into the positioning hole 6, the second slider 94 can be positioned, and the first slider 92 and the disc 97 can also be positioned, which facilitates the stable installation of the outer shell 1.

[0040] The working principle of this utility model is as follows:

[0041] When the charging pile body 12 is used to charge an electric vehicle, the heat generated during the operation of the charging pile body 12 can be transferred through the heat conduction plate 71 to multiple heat dissipation fins 73 that are set outside the outer shell 1 and are equidistantly arranged, so as to facilitate the heat dissipation. It can also enable the electric fan 11 to work, draw in the outside cold air through the air delivery cavity 10 and blow it out towards the outer shell 1 through the electric fan 11, so as to provide air cooling for the multiple heat dissipation fins 73, thereby accelerating the heat loss and dissipation, achieving a good and more efficient heat dissipation effect, and also helping to improve the safety of the operation of the charging pile body 12 and extend its service life. During the air cooling process, the air guide plate 72 with an inclined surface at the rear end is used to guide the air blown out by the electric fan 11 downward and discharge it between the outer shell 1 and the base plate 8. By guiding the air downward, the convection between the incoming air and the return air can be avoided, which facilitates the rapid circulation of cold air and facilitates the rapid removal of heat.

[0042] When installing the outer casing 1, place the outer casing 1 directly in front of the base plate 8 and let the disc 97 pass through the circular hole of the first positioning groove 4. At the same time, let the front extension of the second slider 94 pass through the second positioning groove 5. Then, manually press down the second slider 94 to make it engage with the outer casing 1. When the second slider 94 moves down, the connecting rod 96 can pull the two first sliders 92 to drive the two discs 97 to slide synchronously along the crossbar 91 in the same direction, so that both discs 97 are engaged with the outer casing 1. Then tighten the positioning bolt 98 and insert one end into the positioning hole 6 to achieve the positioning of the first slider 92, the second slider 94 and the disc 97, which facilitates the stable installation of the outer casing 1 and also facilitates the quick disassembly and maintenance of the outer casing 1.

[0043] It should be noted that both the electric fan 11 and the charging pile body 12 are existing products. When the charging pile body 12 is powered on to charge the vehicle, the electric fan 11 is powered on and turned on. The specific circuit layout and control methods are mature technologies. Moreover, the door lock 3 is also an existing product, so it will not be described in detail.

[0044] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any equivalent changes, modifications, substitutions, and variations made by those skilled in the art based on the concept of this utility model and on the basis of existing technology through logical analysis, reasoning, or limited experiments shall be within the scope of protection defined by the claims.
