Abstract
Description
Technical Field
[0001] This utility model relates to the field of charging equipment technology, and in particular to a charging pile. Background Technology
[0002] Outdoor charging stations typically consist of a charging station body and a charging connector. The charging station body connects to a power source, providing power to the charging connector. The charging connector is used to connect to an energy storage device to transfer electrical energy to it. In existing technology, to allow users to easily monitor the charging station's status, an indicator light is installed on the top of the charging station body.

[0030] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0031] Please refer to the following: Figures 1 to 6 The charging pile provided in the embodiment of this utility model will now be described. The first direction is shown as the X direction in the figure.
[0032] like Figures 1 to 3 As shown, the charging pile of this utility model embodiment includes: a pile body 100, an indicator light 200, and a light guide column 300;
[0033] Among them, reference Figure 3 and Figure 4The pile body 100 has a closed light-transmitting portion 110 on its surface; the indicator light 200 is disposed inside the pile body 100; the light guide column 300 is disposed inside the pile body 100; the two ends of the light guide column 300 are a light receiving end 310 and a light emitting end 320, respectively; the light emitting end 320 has a light emitting surface 321, and the light emitting surface 321 faces the light-transmitting portion 110; the light receiving end 310 has a light receiving surface 311, and the light receiving surface 311 faces the indicator light 200; wherein, the indicator light 200 is used to direct light toward the light receiving surface 311; the light guide column 300 can guide the light entering from the light receiving surface 311 to the light emitting surface 321. Since the light emitting surface 321 faces the light-transmitting portion 110, the light emitted from the light emitting surface 321 can exit from the light-transmitting portion 110. The light-transmitting part 110 is sealed to prevent external moisture from seeping into the pile body 100 through the light-transmitting part 110. The light-transmitting part 110 may be composed of transparent or translucent parts so that light can be emitted from the light-transmitting part 110.
[0034] The indicator light 200 is a light source and can be made of LED beads. In this embodiment, the light-transmitting part 110 is located on the upper surface of the pile body 100 so that the user can see the light emitted by the indicator light 200. The light emitting end 320 is located below the light-transmitting part 110. The light emission direction of the indicator light 200 is parallel to the first direction X and intersects the vertical direction. The light emission direction of the LED beads is parallel to the first direction X and intersects the vertical direction. That is, the light emission direction of the indicator light 200 is neither vertical nor up-down. It is not necessary for the indicator light 200 to emit light directly towards the light-transmitting part 110.
[0035] The light guide post 300 is an optical element used to guide and uniformly distribute light. It can be made of materials such as polymethyl methacrylate, acrylic plastic, polycarbonate, and optical-grade glass. Its shape can be set according to the specific optical path and can be straight, arc, curved, or other shapes. When the light guide post 300 is arc or curved, it means that the light guide post 300 is bent and not straight.
[0036] In this embodiment, since the light emitted by the indicator light 200 is directed along the first direction X towards the light receiving surface 311, and the first direction X intersects with the vertical direction, the light guide column 300 is curved to guide and transmit the light emitted by the indicator light 200 to the light emitting surface 321 of the light emitting end 320. This allows the light emitted by the indicator light 200 to be guided along the curved light guide column 300 to the light-transmitting portion 110 on the upper surface of the charging pile 100, causing the top of the charging pile 100 to emit an indicator light to provide feedback on the current usage status of the charging pile to the user, making it convenient for the user to know the current usage status of the charging pile. Therefore, the light emitted by the indicator light 200 does not have to be directed towards the light-transmitting portion 110, allowing the light to be transmitted to the light-transmitting portion. This allows the indicator light 200 to be arranged in other positions below the light-transmitting portion 110, so that the position of the indicator light 200 inside the charging pile 100 is not limited by the position of the light-transmitting portion 110. The indicator light 200 can be placed in other places inside the charging pile 100, making the internal space configuration of the charging pile 100 more flexible. Moreover, the light guide column 300 can be arranged using the gaps between the internal structures of the pile body 100, thereby improving the rational utilization rate of the internal space of the pile body 100.
[0037] Understandably, the charging station has a charging connector 120, which is mounted on the station body 100. To allow the charging connector 120 to connect to the power supply and to control the output voltage of the charging connector 120, the charging station contains a circuit board 500 connected to the power supply. The circuit board 500 connects the charging connector 120 and the indicator light 200, and is an essential component of the charging station. The indicator light 200 can be directly mounted on the circuit board 500 connected to the power supply.
[0038] In this embodiment, the light emitted by the indicator light 200 can be guided to the light-transmitting part 110 through the light guide column 300. Therefore, the indicator light 200 does not need to be placed below the light-transmitting part 110, and there is no need to set an additional circuit board with LED beads below the light-transmitting part 110. Furthermore, there is no need to make an additional waterproof structure for the circuit board with LED beads at the top. Therefore, the production cost of the charging pile can be reduced.
[0039] In addition, in some other embodiments, the light-transmitting part 110 can be located on the left, right, front, or rear side of the charging pile, and the arrangement of the light-transmitting part 110 can be made according to the specific structure of the charging pile.
[0040] In some embodiments of this utility model, reference is made to Figure 3 and Figure 4In order to better allow the light emitted by the indicator light 200 to enter the light guide column 300, the plane where the light receiving surface 311 is located is perpendicular to the first direction X. This allows the light emitted by the indicator light 200 to enter the light receiving surface 311 perpendicularly, which can maximize the reception of the light emitted by the indicator light 200 and reduce the scattering loss of the light when entering the light guide column 300.
[0041] In some embodiments of this utility model, reference is made to Figures 4 to 6 The charging station further includes: a power supply box 400; the power supply box 400 has a receiving cavity 410; the power supply box 400 is disposed inside the charging station body 100 to prevent rainwater from directly washing the outside of the power supply box 400 and to protect the objects inside the power supply box 400; the indicator light 200 is located inside the receiving cavity 410; the power supply box 400 is provided with a through hole 420 communicating with the receiving cavity 410; the light guide post 300 passes through the through hole 420, and the light receiving end 310 is located inside the receiving cavity 410. In other words, the power supply box 400 encloses the indicator light 200 inside the receiving cavity 410 to protect the indicator light 200 and the light receiving end 310 from damage by external objects. Based on the above, the charging pile further includes: a circuit board 500; the circuit board 500 is used to connect to the power supply, and the circuit board 500 is disposed on the power supply box 400 and located in the receiving cavity 410, so that the power supply box 400 can protect the circuit board 500 connected to the power supply; the indicator light 200 is disposed on one side of the circuit board 500, that is, the indicator light 200 is located on the circuit board 500 connected to the power supply, making full use of the necessary components on the charging pile, eliminating the need to additionally set a circuit board with LED beads below the light-transmitting part 110, thus saving the production cost of the charging pile.
[0042] In some embodiments of this utility model, reference is made to Figures 4 to 6 The side of the circuit board 500 facing the indicator light 200 is parallel to the vertical direction, and the first direction X is perpendicular to the vertical direction. Since the circuit board 500 is a flat plate, meaning the plane containing the circuit board 500 is parallel to the vertical direction, the indicator light 200 emits light in a left-right direction. Even if the indicator light 200 does not emit light towards the top light-transmitting part 110, the light can still be guided to the light-transmitting part 110 using the light guide column 300. This allows for multiple position options for the indicator light 200, facilitating adjustment of its position when upgrading various functions of the charging pile and preventing interference with other components due to the indicator light 200's position.
[0043] In some embodiments of this utility model, reference is made to Figures 4 to 6Since the light-emitting end 320 of the light guide column 300 needs to be located below the light-transmitting part 110, in order to reduce the length of the light guide column 300, the through hole 420 is set on the top of the power box 400. This allows the light guide column 300 to directly extend into the receiving cavity 410 of the power box 400 from the through hole 420 on the top of the power box 400, so that the light receiving end of the light guide column 300 is close to the indicator light 200, so that the light from the indicator light 200 can be guided along the light guide column 300 to the light-transmitting part 110 on the top of the charging pile 100. Compared with the solution of setting the through hole 420 on the side or bottom of the power box 400, setting the through hole 420 on the top can effectively shorten the length of the light guide column 300 and reduce the production cost of the charging pile.
[0044] In some embodiments of this utility model, reference is made to Figures 4 to 6 The power supply box 400 has a fixing cylinder 430 on its top. The through hole 420 extends vertically through the fixing cylinder 430. The middle part of the light guide column 300 is located inside the fixing cylinder 430, and the light emitting end 320 is located above the fixing cylinder 430. The fixing cylinder 430 is used to support and fix the light guide column 300, so that the light guide column 300 is installed in a fixed position, ensuring that the light receiving end 310 of the light guide column 300 corresponds to the indicator light 200, and ensuring that the light emitting end 320 is aligned with the light-transmitting part 110.
[0045] In some embodiments of this utility model, reference is made to Figures 4 to 6 A sealing ring 330 is provided on the outer side of the light guide post 300, which is used to seal the upper end of the through hole 420. The sealing ring 330 cooperates with the through hole 420 to fix the position of the light guide post 300, prevent the light guide post 300 from shaking, and ensure stable light transmission. Specifically, the outer periphery of the sealing ring 330 is tightly fitted to the inner wall of the fixing cylinder 430 to seal the upper end of the through hole 420, thereby achieving a sealing effect and preventing moisture from entering the power box 400 through the through hole 420.
[0046] In some embodiments of this utility model, reference is made to Figures 4 to 6The outer side of the light guide post 300 is also provided with a guide ring 340 that can pass through the through hole 420. The shape of the guide ring 340 is adapted to the through hole 420. The guide ring 340 is located below the sealing ring 330 and is used to cover the lower end of the through hole 420. When the light guide post 300 extends downward from the upper end of the fixed cylinder 430, there is a certain gap between the outer periphery of the guide ring 340 and the inner wall of the fixed cylinder 430, so that the guide ring 340 guides the light guide post 300 into the through hole 420 and can fix the orientation of the light guide post 300 so that the light receiving end 310 is aligned with the indicator light 200. Moreover, when the sealing ring 330 closes the upper end of the fixed cylinder 430, the guide ring 340 can reach the lower end of the fixed cylinder 430 to cover the lower end of the fixed cylinder 430. It should be noted that, in order to prevent the light guide post 300 from shaking randomly, the through hole 420 can be polygonal, strip-shaped, or other shapes, and the outer side of the corresponding guide ring 340 is also polygonal, strip-shaped, or other shapes, so that the light guide post 300 can be positioned and installed.
[0047] In some embodiments of this utility model, reference is made to Figures 4 to 6 The light-transmitting part 110 includes a light-transmitting opening 111 and a light-transmitting cover 112. The light-transmitting opening 111 is disposed on the surface of the charging pile body 100, and the light-transmitting cover 112 is disposed inside the light-transmitting opening 111 and closes the light-transmitting opening 111. The light-transmitting cover 112 can be a semi-transparent or transparent part to facilitate light to pass through the light-transmitting part 110, so as to provide feedback on the current usage status of the charging pile to the user.
[0048] In summary, in this embodiment, the indicator light 200 inside the charging pile body 100 can guide light to the top light-transmitting part 110 through the light guide column 300, so that the charging pile body 100 emits indicator light to provide feedback to the user on the current usage status of the charging pile. The shape of the light guide column 300 is set according to the specific structure. The curved light guide column 300 allows the light emitted by the indicator light 200 to be transmitted along the curved light guide column 300. Therefore, even if the light emitted by the indicator light 200 is not directed towards the light-transmitting part 110, the light can still be transmitted to the light-transmitting part 110. That is, the arrangement position of the indicator light 200 is not limited by the position of the light-transmitting part 110. Thus, the charging pile does not need to additionally set a circuit board with LED beads below the light-transmitting part 110, nor does it need to additionally waterproof the circuit board with LED beads at the top. This can reduce the production cost of the charging pile and improve its economic benefits.
[0049] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this utility model, and these improvements and substitutions should also be considered within the protection scope of this utility model.
