Description

Technical Field

[0001] This application relates to the field of two-wheeled vehicles, and in particular to a charging terminal heat dissipation system and a charging terminal. Background Technology

[0002] Electric vehicle charging terminals require efficient heat dissipation systems to ensure stable operation. A common forced-air cooling solution involves opening ventilation holes in the enclosure and installing fans to draw in cool air and remove heat from the heating elements. However, external dust easily accumulates inside the enclosure, so air inlets need to be equipped with air filters to remove dust. In existing technologies, the filters are directly installed inside the enclosure or close to the inner wall. Replacing them requires reaching into the narrow space filled with electronic components and cables, increasing the risk of touching live parts or damaging components, posing a risk of electric shock, and making maintenance inconvenient. Furthermore, filter replacement relies on regular maintenance inspections. If inspections are not timely or the amount of dust in the environment is abnormal, the filters may become clogged prematurely, leading to a risk of overheating. Utility Model Content

A sliding member is slidably disposed within the air inlet. An installation cavity is formed within the sliding member, and a filter device is placed in the installation cavity. The installation cavity has a replacement opening through which the filter device can pass. The sliding member has a working position and a maintenance position. When the sliding member is in the working position, the replacement opening is located inside the housing. When the sliding member is in the maintenance position, the replacement opening is located outside the housing. A fan assembly, connected to the sliding member, is configured to drive outside air through the filter and into the housing; A light intensity detection unit is disposed on the sliding member and near the replacement opening, and is used to detect the light intensity on the side of the filter device near the fan assembly; A current detection unit is used to detect the operating current of the fan assembly. The control unit is electrically connected to the light intensity detection unit and the current detection unit, respectively.

[0005] The second aspect of this application provides a charging terminal heat dissipation system, including the first aspect of the above-described embodiment.

[0006] The charging terminal heat dissipation system and charging terminal of this application embodiment can slide within the air inlet of the housing via a sliding member. During operation, the replacement opening is located inside the housing, ensuring that the filter device is adapted to the airflow path to achieve normal air filtration and heat dissipation functions. During maintenance, the replacement opening is moved to the outside of the housing, eliminating the need to insert the filter device into the narrow space filled with electronic components and cables inside the housing, effectively avoiding the risk of electric shock and component damage, and greatly improving the convenience of filter device maintenance. At the same time, the light intensity detection unit is located on the sliding member and close to the replacement opening, which can detect changes in light intensity on the side of the filter device near the fan assembly in real time, while the current detection unit can capture abnormal operating current of the fan assembly in real time.

[0013] In the description of this application, it should be noted that, unless otherwise explicitly defined, terms such as "setup," "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 application in conjunction with the specific content of the technical solution.

[0014] The technical solution of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this application, not all embodiments.

[0015] The following is for reference. Figures 2 to 10 This application describes a charging terminal heat dissipation system and a charging terminal according to embodiments thereof.

[0016] like Figures 1 to 10As shown, the charging terminal heat dissipation system of this application embodiment includes: The enclosure 100 has an air inlet 110 and an air outlet 120. The sliding member 200 is slidably disposed in the air inlet 110. An installation cavity 201 is formed in the sliding member 200. A filter device 300 is placed in the installation cavity 201. The installation cavity 201 has a replacement opening through which the filter device 300 can pass. The sliding member 200 has a working position and a maintenance position. When the sliding member 200 is in the working position, the replacement opening is located inside the housing 100. When the sliding member 200 is in the maintenance position, the replacement opening is located outside the housing 100. Fan assembly 400, connected to sliding member 200, is configured to drive outside air through filter device 300 and into housing 100; The light intensity detection unit 710 is mounted on the slider 200 and positioned close to the replacement opening. It is used to detect the light intensity of the filter device 300 on the side close to the fan assembly 400. The current detection unit 720 is used to detect the operating current of the fan assembly 400. The control unit 730 is electrically connected to the light intensity detection unit 710 and the current detection unit 720, respectively.

[0017] In this embodiment, the sliding member 200 can slide within the air inlet 110 of the housing 100. During operation, the replacement opening is located inside the housing 100, ensuring that the filter device 300 is adapted to the airflow path to achieve normal air filtration and heat dissipation functions. During maintenance, the replacement opening is moved to the outside of the housing 100, eliminating the need to insert the filter device 300 into the narrow space filled with electronic components and cables inside the housing, effectively avoiding the risk of electric shock and component damage, and significantly improving the convenience of maintaining the filter device 300; simultaneously, the light intensity detection unit 7 The 10 unit is mounted on the sliding member 200 and close to the replacement opening. It can detect changes in light intensity on the side of the filter device 300 near the fan assembly 400 in real time. The current detection unit 720 can capture abnormal operating current of the fan assembly 400 in real time. The control unit 730 is electrically connected to the light intensity detection unit 710 and the current detection unit 720, which can realize automatic early warning of filter device 300 blockage and fan failure. This reduces the lag of relying on manual inspection, prevents the heat dissipation efficiency from decreasing due to filter device 300 blockage, and can reduce operation and maintenance costs.

[0018] The aforementioned enclosure 100 is equipped with an opening and closing door for easy maintenance and repair.

[0019] The aforementioned slider 200 can be manually pushed by the operator to switch between the working position and the maintenance position.

[0020] The aforementioned fan assembly 400 is configured to drive outside air through the filter device 300 and into the housing 100. After the air enters the housing 100, it can dissipate heat inside the housing 100 and then be discharged from the air outlet 120.

[0021] The aforementioned fan assembly 400 and filter device 300 are integrated within the sliding member 200, optimizing the internal space of the housing 100.

[0022] The aforementioned sliding component 200, filter device 300, and fan assembly 400 can be produced, tested, and replaced as an independent module, making them easy to inspect and maintain.

[0023] The aforementioned filtration device 300 can be either a filter element or a filter screen. When using a filter element, a thinner filter element is used to improve ventilation. Both thin filter elements and filter screens have good light transmittance, providing a theoretical basis for light intensity detection.

[0024] The light intensity detection unit 710 can directly use a light intensity sensor and should be positioned as directly opposite the filter device 300 as possible to better detect light intensity while reducing the impact of light entering from the air outlet 120 on the detection results.

[0025] The aforementioned current detection unit 720 can detect the operating current of the fan. It can be understood that for a normally operating fan, when there is difficulty in air intake, a stall condition will occur. At this time, the fan current will be higher than the operating current during normal operation, but it will not exceed the overcurrent value. When the fan is abnormal, the current may be abnormally large or abnormally small.

[0026] Specifically, when the filter device 300 is covered with dust, the light transmittance of the filter device 300 decreases. At this time, the light intensity detection unit 710 detects that the light intensity is lower than the low light intensity threshold, and the control unit 730 can issue an alarm message. Conversely, when the filter device 300 is not covered with dust, the light transmittance of the filter device 300 still meets the usage requirements. At this time, the light intensity detection unit 710 detects that the light intensity is higher than the low light intensity threshold, and the control unit 730 will not output an alarm message.

[0027] It should be noted that, to avoid false alarms, if the light intensity detection unit 710 detects that the light intensity is below the low light intensity threshold, the current detection unit 720 can be used to detect the operating current of the fan assembly 400. If the operating current is higher than the normal operating current, i.e., higher than the preset high current threshold, it can be determined that the filter device 300 is full of dust and needs to be replaced. Conversely, if there is no increase in the operating current, there is a possibility that the light intensity detection unit 710 is malfunctioning. Furthermore, if the fan exceeds the preset high current threshold, but is not abnormally large, and the light intensity detection unit 710 still detects that the light intensity is higher than the low light intensity threshold, it indicates that the fan may be malfunctioning.

[0028] The control unit 730 mentioned above can be at least one of DSP, microcontroller, ARM, and PLC, and specifically an STM32 series processor can be selected.

[0029] The aforementioned control unit 730 can be the controller in the original circuit element 600 of the charging terminal, or it can be a separately configured controller. It is understood that, in order to reduce costs, the original controller of the charging terminal can be used directly, while if a more stable operating environment is required, a separate controller can be used. This application does not specifically limit the choice of method.

[0030] The aforementioned circuit element 600 includes at least a functional circuit that enables the charging terminal to charge the battery normally and a functional circuit that enables data interaction with the remote monitoring center. The circuit element 600 should be a technical means that should be known to those skilled in the art.

[0031] In some implementations, reference Figure 3 , Figure 4 The aforementioned charging terminal heat dissipation system also includes: A locking element 500 is provided inside the housing 100, and the locking element 500 is configured to fix the sliding element 200 when the sliding element 200 is moved to the working position and the maintenance position.

[0032] The aforementioned locking element 500 can fix the sliding element 200 in both the working and maintenance positions. The locking element 500 ensures that in the working position, the sliding element 200 will not shift due to vibration or airflow reaction force, and the air inlet 110 accurately aligns with the sliding element 200, reducing air leakage and ensuring heat dissipation efficiency. Since the locking element 500 is located inside the housing 100, the sliding element 200 cannot be pulled out from the outside during normal operation, which can, to some extent, prevent the theft of the filter device 300 in the housing 100 located in public areas. In the maintenance position, the sliding element 200 can remain stably on the outside, facilitating the replacement of the filter device 300 with both hands. The filter device 300 replacement process is simplified as follows: the locking element 500 releases the fixation on the sliding element 200, the sliding element 200 is pulled out, the filter device 300 is replaced through the replacement opening, the sliding element 200 is pushed back, and the locking element 500 fixes the sliding element 200, improving the efficiency of filter device 300 replacement.

[0033] In some implementations, reference Figure 1 , Figure 3 The fan assembly 400 includes multiple cooling fans arranged sequentially along the height direction of the housing 100. All cooling fans are electrically connected to the control unit 730. The current detection unit 720 includes multiple current sensors, which are used to detect the operating current of the multiple cooling fans.

[0034] The aforementioned fan group 400 has multiple cooling fans arranged along the height of the enclosure 100, which can fully adapt to the internal space of the enclosure 100, improve the uniformity of air intake, and ensure the heat dissipation effect on the components inside the enclosure; multiple current sensors detect the operating current of each cooling fan, which can accurately locate a single faulty fan, avoid the interruption of overall heat dissipation due to a single fan failure, reduce the difficulty of operation and maintenance troubleshooting, and work with the control unit 730 to achieve accurate fault early warning, further ensuring the stable operation of the charging terminal.

[0035] In some embodiments, the light intensity detection unit 710 is disposed on the frame of any cooling fan and located on the side close to the filter device 300.

[0036] In this embodiment, the light intensity detection unit 710 is positioned on any cooling fan frame near the filter device 300. This allows for stable installation via the fan frame, eliminating the need for additional mounting structures. It also adapts to the integrated layout of the sliding component 200 and the fan, without disrupting the original heatsink structure. Furthermore, this position, being close to the filter element, allows for direct detection of light intensity changes near the fan, accurately capturing dust accumulation on the filter element and avoiding detection lag. Additionally, its placement on the cooling fan frame near the filter device 300 also better avoids interference from light from the exhaust vent 120, improving detection accuracy.

[0037] In some implementations, reference Figure 1The aforementioned charging terminal heat dissipation system also includes a temperature detection unit 740 electrically connected to the control unit 730, which is used to detect the temperature inside the housing 100.

[0038] In this embodiment, the temperature detection unit 740 detects the temperature inside the housing 100 and is electrically connected to the control unit 730. It can monitor the heat dissipation effect of the housing 100 in real time. When the temperature rises abnormally due to filter blockage, fan failure, etc., the control unit 730 can capture and respond in time to prevent the components inside the housing from being damaged by high temperature, further ensuring the stable operation of the charging terminal. It does not require additional complex structure and is compatible with the original heat sink design.

[0039] In some embodiments, the temperature detection unit 740 is disposed on the inner side wall of the housing 100 and away from the fan assembly 400.

[0040] In this embodiment, the temperature detection unit 740 is located on the inner wall of the housing 100 and away from the fan assembly 400. This avoids interference from localized cold air near the fan, accurately detects the overall internal temperature of the housing 100, truly reflects the heat dissipation effect, and avoids detection deviations caused by localized temperature differences. Simultaneously, stable installation is achieved using the inner wall of the housing 100, eliminating the need for additional installation structures, adapting to the original heat sink layout, and working in conjunction with the control unit 730 to promptly respond to temperature anomalies, ensuring stable operation of the charging terminal.

[0041] In some implementations, reference Figure 1 The aforementioned charging terminal heat dissipation system also includes an alarm module 750 electrically connected to the control unit 730.

[0042] In this embodiment, by adding an alarm module 750, an alarm can be automatically triggered when the light intensity is lower than the light intensity threshold, the operating current of the cooling fan in the fan group 400 is too high, or the temperature inside the enclosure 100 is too high. At the same time, if the alarm module 750 has remote communication transmission capability, it can provide remote early warning, allowing maintenance personnel to proactively troubleshoot the fault as early as possible and avoid dangerous situations.

[0043] The alarm module 750 mentioned above can be an audible and visual alarm to alert local personnel to stay away and avoid casualties.

[0044] The alarm module 750 mentioned above can also be a communication module to provide remote early warning and remind personnel in the central control center to conduct early investigation of potential dangers.

[0045] The alarm module 750 mentioned above can also be a combination of an audible and visual alarm and a communication module.

[0046] In some implementations, refer to Figures 6 to 8As shown, the sliding member 200 includes an outer panel 210 and an inner support plate 220. The outer panel 210 and the inner support plate 220 are vertically arranged. The upper end of the outer panel 210 and the upper end of the inner support plate 220 are connected by a top plate 230, and the lower end of the outer panel 210 and the lower end of the inner support plate 220 are connected by a bottom plate 240. The mounting cavity 201 is formed by the outer panel 210, the inner support plate 220, the top plate 230 and the bottom plate 240. The outer panel 210 has a plurality of first flow holes 211, and the inner support plate 220 has a plurality of second flow holes 221. The fan assembly 400 is installed on the side of the inner support plate 220 away from the mounting cavity 201.

[0047] The outer panel 210 and the inner support plate 220 are both made of aluminum alloy or steel alloy.

[0048] The outer panel 210 and the inner support plate 220 are parallel to each other.

[0049] The aforementioned top plate 230 is welded to the outer panel 210 and the inner support plate 220.

[0050] The aforementioned base plate 240 is welded to the outer panel 210 and the inner support plate 220.

[0051] The first flow hole 211 and the second flow hole 221 provide air circulation on both sides of the filter device 300.

[0052] The outer panel 210, inner support plate 220, top plate 230 and bottom plate 240 together form a sturdy frame, providing a closed and independent air intake duct for the internal filter device 300, ensuring filtration efficiency.

[0053] Reference Figure 7 and Figure 8 As shown, in some embodiments, the outer panel 210 has multiple rainproof sections 212 on the side away from the mounting cavity 201. The rainproof sections 212 are used to prevent rainwater from entering the first flow hole 211. The rainproof section 212 is a curved arc-shaped plate, and each first flow hole 211 is provided with a rainproof section 212. The arc-shaped plate forms an eaves shape, effectively preventing rainwater, splashing water droplets, and even large condensate from directly entering the first flow hole 211, ensuring the normal operation of the equipment in rainy and snowy weather.

[0054] In some implementations, refer to Figures 6 to 8As shown, both the top plate 230 and the bottom plate 240 are connected to the housing 100 via guide members 250. Four guide members 250 are symmetrically arranged, and they are linear guides installed using bolt connections. A slider that mates with the linear guides is bolted to the inside of the housing 100. Since the slider 200 is primarily subjected to gravity, it needs vertical support. Linear guide pairs, as high-precision standard components, are easy to procure and install. The symmetrical arrangement of the four linear guides ensures that the slider 200 operates extremely smoothly and stably during pushing and pulling, and can withstand its weight.

[0055] Reference Figure 4 , Figure 7 and Figure 8 As shown, in some embodiments, the top plate 230 and the bottom plate 240 are bolted together with a stop 260. The stop 260 is bolted to the top plate 230 and the bottom plate 240, which is very simple to process and install, and has low manufacturing cost. The stop 260 can abut against the housing 100. The outer panel 210 is larger than the air inlet 110. The outer panel 210, the stop 260, and the side wall of the housing 100 work together to limit the travel of the slider 200. The purpose of limiting the travel of the slider 200 is to prevent the slider 200 from disengaging from the air inlet 110. This prevents accidents caused by the operator pulling the slider 200 out completely due to excessive force.

[0056] In some implementations, refer to Figure 3 and Figure 6 As shown, the portion of the slider 200 located within the housing 100 is bolted to a handle 270. The handle 270 provides a point of leverage for the operator to push or pull the slider 200. The handle 270 is ergonomically designed, allowing for a firm grip, making the pushing and pulling motion smoother, and reducing operational difficulty and physical exertion.

[0057] In some implementations, refer to Figure 4 and Figure 9 As shown, the locking member 500 includes a pin 510 and a fixing part 520. The fixing part 520 is connected to the inner side wall of the housing 100. The fixing part 520 has an insertion hole 521. The pin 510 passes through the insertion hole 521. The extension direction of the pin 510 is perpendicular to the movement direction of the sliding member 200. The top plate 230 has a working fixing hole 231 and a maintenance fixing hole 232. When the sliding member 200 is in the working position, the pin 510 is inserted into the working fixing hole 231. When the sliding member 200 is in the maintenance position, the pin 510 is inserted into the maintenance fixing hole 232.

[0058] The aforementioned locking component 500 is composed of a pin 510 and a fixed part 520 with holes, and has the advantages of low manufacturing cost, low failure rate and long service life.

[0059] The aforementioned fixing part 520 is disposed above the sliding member 200.

[0060] Both the aforementioned socket 521 and pin 510 are vertically positioned.

[0061] The aforementioned pin 510 directly blocks the movement path of the slider 200 on the guide rail, providing a reliable locking force.

[0062] When the aforementioned slider 200 is in the working position, the pin 510 is inserted into the working fixing hole 231 in a direction perpendicular to the movement of the slider 200 to resist the displacement tendency of the slider 200 caused by equipment vibration or accidental collision.

[0063] When the aforementioned sliding member 200 is in the maintenance position, the pin 510 is inserted into the maintenance fixing hole 232 in a direction perpendicular to the movement of the sliding member 200 to resist the displacement tendency of the sliding member 200 caused by equipment vibration or accidental collision.

[0064] In some embodiments, side panels 130 are vertically welded to the inner wall of the housing 100, and the side panels 130 are used to guide the sliding member 200. Two side panels 130 are provided, located on the front and rear sides of the sliding member 200 respectively. The side panels 130 limit the forward and backward movement of the sliding member 200, ensuring that the sliding member 200 maintains a linear movement during pushing and pulling, and does not wobble back and forth. When the sliding member 200 is in the working position, the side panels 130 block the front and rear sides of the filter device 300, closing the replacement opening, thus forming a complete airflow channel around the filter device 300. This ensures that the air entering the housing 100 must first pass through the filter device 300, guaranteeing filtration efficiency.

[0065] This application also provides a charging terminal, which includes the above-described charging terminal heat dissipation system.

[0066] It should be noted that since the charging terminal can adopt all the technical solutions of the above-mentioned charging terminal heat dissipation system, it has at least all the beneficial effects brought about by the above-mentioned technical solutions of the charging terminal heat dissipation system. These additional beneficial effects will not be elaborated here.

[0067] It should be clarified that this application is not limited to the specific configurations and processes described above and shown in the figures. For the sake of brevity, detailed descriptions of known methods are omitted here. In the above embodiments, several specific steps are described and shown as examples. However, the method process of this application is not limited to the specific steps described and shown. Those skilled in the art can make various changes, modifications, and additions, or change the order of steps, after understanding the spirit of this application.

[0068] The above are merely specific embodiments of this application. Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific working processes of the systems, modules, and units described above can be referred to the corresponding processes in the foregoing method embodiments, and will not be repeated here. It should be understood that the protection scope of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the protection scope of this application.
