Detailed Implementation
[0044] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0045] Example:
[0046] like Figures 1-6 As shown, the charging pile host cabinet provided in this embodiment includes a cabinet 100, a sound-absorbing structure 300, a filter, and a filter screen 500, wherein:
[0047] The cabinet 100 has an air inlet and an air outlet. The interior of the cabinet 100 forms an installation space for installing various electrical components required by the charging stack main unit (such as charging modules, switching modules, power control modules, etc.). It is worth noting that the charging stack includes a main unit and a terminal. The main unit is electrically connected to the terminal, thereby supplying power to the terminal and controlling the terminal's operating status. Therefore, various electrical components are installed inside the main unit's cabinet 100. This is existing technology and will not be described in detail here.
[0048] An air inlet frame 120 and an air outlet frame 140 are connected to the air inlet and air outlet respectively. The air inlet frame 120 is adapted to the air inlet, and the air outlet frame 140 is adapted to the air outlet. A silencer structure 300 is installed in both the air inlet frame 120 and the air outlet frame 140. A fan 400 is installed in the air outlet frame 140. The fan 400 is used to draw air in from the air inlet frame 120 and blow it out from the air outlet frame 140. The fan 400 is electrically connected to the electrical control components inside the main unit cabinet, thereby supplying power to the fan 400 and controlling its operation. The silencer structure 300 of the air outlet frame 140 is located outside the fan 400. A filter screen 500 is installed in the air inlet frame 120. The filter screen 500 is used to filter the air drawn in from the air inlet frame 120, preventing impurities from the external environment from entering the cabinet 100 of the main unit cabinet.
[0049] With the above structure, when the fan 400 is running, it draws in air from the air inlet frame 120 and blows it out from the air outlet frame 140, thereby creating airflow inside the cabinet 100 to cool the electrical components installed inside the cabinet 100. Since both the air inlet frame 120 and the air outlet frame 140 are equipped with silencing structures 300, and the silencing structure 300 of the air outlet frame 140 is located outside the fan 400, the fan 400 and the electrical components inside the cabinet 100 are located between the silencing structures 300 in the air inlet frame 120 and the silencing structures 300 in the air outlet frame 140. Therefore, the silencing structure 300 can eliminate some of the noise emitted outwards by the charging host and the fan 400 during operation, resulting in lower noise pollution to the outside world during the operation of the charging host.
[0050] An optional implementation of this embodiment is as follows: the air inlet is located on the front wall of the cabinet 100, and the air outlet is located on the rear wall of the cabinet 100. Since other components are typically placed on the left and right sides of the charging pile host cabinet, and the air inlets and outlets on existing charging pile host cabinets are usually located on the left and right walls of the cabinet, these other components will affect the air intake and exhaust during air intake and exhaust. Therefore, the air inlet and outlet on the charging pile host cabinet provided in this embodiment are respectively located on the front and rear walls of the cabinet 100, thus allowing for better air intake and exhaust. Of course, the air inlet and outlet on the cabinet 100 provided in this embodiment can also be located on the left and right walls, respectively, as in the prior art.
[0051] In addition, the silencing structure 300 at the air inlet frame 120 is located on the outside of the filter screen 500. In this way, the silencing structure 300 can eliminate some of the noise generated when the air passes through the filter screen 500, thus achieving a better silencing effect. Of course, the silencing structure 300 at the air inlet frame 120 can also be located on the inside of the filter screen 500.
[0052] It is worth noting that the "inner side" and "outer side" mentioned above refer to the interior and exterior of the cabinet 100, respectively. Specifically, in this embodiment, a sealing plate 600 is installed at one end of the air outlet frame 140 near the interior of the cabinet 100, and a mounting hole is provided on the sealing plate 600, in which the aforementioned fan 400 is installed.
[0053] An optional implementation of this embodiment is as follows: In this embodiment, both the air inlet frame 120 and the air outlet frame 140 are frames 200. The frame 200 is a frame structure that runs through the front and back and is assembled from sheet metal. The above-mentioned sound-absorbing structure 300 includes several blades 310 with sound-absorbing function. Several blades 310 are installed in the frame 200, and several blades 310 and the frame 200 form a louver.
[0054] Thus, this embodiment has two louvers as described above, which are installed at the air inlet and air outlet respectively. The blades 310 of the louvers have a sound-absorbing function. Since each louver has several blades 310, the sound-absorbing effect of several blades 310 is better. Moreover, the gap between two adjacent blades 310 in the louver can maintain a good ventilation effect, so that the wind can easily pass through several blades 310.
[0055] Of course, the aforementioned sound-absorbing structure 300 can also be a sound-absorbing sheet bonded to the inner wall of the frame 200.
[0056] An optional implementation of this embodiment is as follows: The blade 310 includes a mounting component 311 and sound-absorbing cotton 312, wherein:
[0057] The mounting component 311 is detachably and fixedly connected to the inner wall of the frame 200. A sandwich layer is provided within the mounting component 311, and the sound-absorbing cotton 312 is sandwiched within this layer, thereby installing the sound-absorbing cotton 312 inside the blade 310. In this embodiment, the mounting component 311 can be understood as a mounting bracket, while the sound-absorbing cotton 312 is a block-shaped structure with a certain thickness. The sound-absorbing cotton 312 and the mounting component 311 together constitute the blade 310, and the sound-absorbing cotton 312 can absorb noise, thus achieving a sound-absorbing function.
[0058] Optionally, the aforementioned mounting component 311 includes a top plate 3111, two side plates 3112, and two bottom plates 3113, wherein:
[0059] The top plate 3111, side plates 3112, and bottom plate 3113 are all thin plates. Two side plates 3112 are fixed to the bottom walls at both ends of the top plate 3111. The side plates 3112 are bolted to the inner wall of the frame 200, thus detachably mounting the entire mounting component 311 onto the frame 200. Alternatively, the side plates 3112 can be riveted to the frame 200. Two bottom plates 3113 are fixed to the bottom ends of the two side plates 3112. It is worth noting that the connection between the top plate 3111, side plates 3112, and bottom plate 3113 can be welded or integrally formed, ensuring a stable connection between the top plate 3111, side plates 3112, and bottom plate 3113.
[0060] Specifically, two side panels 3112 are respectively connected to the inner walls of the left and right sides of the frame 200, while the top panel 3111 spans the frame 200. A sandwich structure is formed between the top panel 3111, the two side panels 3112, and the two bottom panels 3113. To illustrate more clearly, in this embodiment, the top panel 3111, the two side panels 3112, and the two bottom panels 3113 actually form a downward-facing "C"-shaped structure. The sound-absorbing cotton 312 is placed between the top panel 3111, the two side panels 3112, and the two bottom panels 3113. Specifically, the sound-absorbing cotton 312 overlaps the bottom panel 3113. The two side panels 3112 position and limit the left and right positions of the sound-absorbing cotton 312, while the top panel 3111 presses down on the sound-absorbing cotton 312. This ensures that the sound-absorbing cotton 312 is securely installed within the frame 200. Furthermore, the above structure forms a front opening and a rear opening on the front and rear sides of the mounting member 311, respectively, so that the sound-absorbing cotton 312 can be inserted into the above-mentioned interlayer.
[0061] Of course, the aforementioned mounting component 311 can also be two clamping grooves installed on the left inner wall and right inner wall of the frame 200 respectively, with the two ends of the sound-absorbing cotton 312 clamped in the two clamping grooves respectively.
[0062] Since the top plate 3111 restricts the freedom of the sound-absorbing cotton 312 from above in the aforementioned mounting component 311, and most of the bottom area of the sound-absorbing cotton 312 is actually suspended, in order to prevent the middle of the sound-absorbing cotton 312 from collapsing downwards, in this embodiment, a connecting plate 3114 is also fixed between the two aforementioned bottom plates 3113. The connecting plate 3114 is located below the sound-absorbing cotton 312. Specifically, the connecting plate 3114 is welded to the bottom plate 3113. In this way, when the middle of the sound-absorbing cotton 312 collapses downwards, the connecting plate 3114 can support the sound-absorbing cotton 312. Of course, more importantly, the connecting plate 3114 connects the two bottom plates 3113, thereby enhancing the structural strength of the mounting component 311.
[0063] Optionally, in this embodiment, the blade 310 is installed at an angle in the frame 200, with the angle pointing outward and downward toward the outside of the cabinet 100, that is, the front opening of the mounting member 311 is located below its rear opening. Specifically, the angle of inclination of the blade 310 is 45°, but of course, the angle of inclination can also be 30° or 60°, etc.
[0064] An optional implementation of this embodiment is as follows: A first door panel 110 is also installed at the air inlet, and a second door panel 130 is also installed at the air outlet. It should be noted that the first door panel 110 and the second door panel 130 are installed in the same way as conventional embedded doors, and are locked to the cabinet 100 by a lock body.
[0065] The aforementioned air inlet frame 120 is bolted to the first door panel 110 and located on the side closer to the interior of the cabinet 100. The air outlet frame 140 is bolted to the second door panel 130 and located on the side closer to the interior of the cabinet 100, thus installing the air inlet frame 120 at the air inlet and the air outlet frame 140 at the air outlet. Furthermore, when the first door panel 110 is opened, the air inlet frame 120 can be removed from the cabinet 100, and when the second door panel is opened, the air outlet frame 140 can be removed from the cabinet 100, facilitating the replacement and maintenance of the aforementioned sound-absorbing cotton 312. The first door panel 110 and the second door panel 130 protect the aforementioned louvers from the outside, not only protecting the louvers but also making the overall appearance of the charging pile main unit cabinet more aesthetically pleasing.
[0066] Several air holes are provided in both the first door panel 110 and the second door panel 130 to allow air to pass through.
[0067] Of course, the air inlet frame 120 can also be directly welded to the inner wall of the air inlet, and the air outlet frame 140 can be directly welded to the inner wall of the air outlet.
[0068] To enhance the structural strength of the first door panel 110 and the second door panel 130, in this embodiment, reinforcing ribs 150 are welded to both the first door panel 110 and the second door panel 130. These reinforcing ribs 150 are located on the inner side of the cabinet body 100. Each of the aforementioned louver blades 310 has a reinforcing rib 150 on its side. Specifically, the reinforcing rib 150 blocks the front opening of the mounting member 311 to contain the sound-absorbing cotton 312 within the interlayer.
[0069] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope described in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
