Description

Technical Field

[0001] This utility model belongs to the field of charging pile maintenance technology, and specifically relates to a charging pile maintenance device. Background Technology

[0002] A charging station is a device that provides electrical energy to electric vehicles. The input end of the charging station is directly connected to the AC power grid, and the output end is equipped with a charging plug. When in use, the electric vehicle is charged by connecting the charging plug to the car's charging interface. In order to ensure the safety and stability of the charging station, it is usually necessary to inspect and maintain the charging station regularly.

[0003] Portable charging pile testers are common charging pile maintenance devices. Due to their advantages of ease of use, rapid testing, and high efficiency, they are widely used in the maintenance of charging piles. Currently, common portable charging pile testers mainly consist of a power supply module, a load simulation module, a communication module, a data acquisition and processing module, a safety protection module, and a human-machine interface. In use, the charging interface of the charging pile is connected to the interface of the portable charging pile tester. Subsequently, the power supply module, load simulation module, communication module, and data acquisition and processing module detect parameters such as output voltage, current, and power of the charging pile.

[0004] In order to ensure the advantages of small size and ease of use, most of the existing portable charging pile testers have integrated their internal modules. However, during actual maintenance, the portable charging pile testers will generate heat due to the influence of current and resistance. At the same time, the confined space will also cause heat to accumulate. This makes the portable charging pile testers prone to heat buildup during maintenance. The accumulation of heat will not only affect the service life of the portable charging pile testers, but also affect the accuracy of the test.

[0005] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a charging pile maintenance device.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

Detailed Implementation

[0030] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0031] like Figures 1 to 6 As shown, a charging pile maintenance device in one embodiment of the present invention includes: a housing 1, an integrated module 101, a heat dissipation mechanism 2, and a conductive heat dissipation mechanism 3.

[0032] like Figures 1 to 4 As shown, an integrated module 101 is installed inside the housing 1. The integrated module 101 is used to detect the parameters of the charging pile.

[0033] like Figures 1 to 4 As shown, a cover 102 is hinged to one side of the housing 1. The cover 102 and the housing 1 cooperate to form a closed box, thereby providing closed protection for the integrated module 101.

[0034] like Figures 1 to 4 As shown, multiple evenly distributed support columns 103 are fixedly assembled at the bottom of the housing 1. The housing 1 is supported and positioned by the multiple support columns 103.

[0035] like Figures 1 to 4 As shown, the heat dissipation mechanism 2 is fixedly mounted on the outside of the integrated module 101. The heat dissipation mechanism 2 includes a support and positioning ring 201, which is fitted onto the top of the integrated module 101. The support and positioning ring 201 is used to fix and limit the integrated module 101.

[0036] Specifically, multiple evenly distributed exhaust holes 205 are provided above the supporting positioning ring 201, and all exhaust holes 205 are connected to the guide cavity 203. The gas in the guide cavity 203 is discharged through the multiple exhaust holes 205, thereby facilitating heat dissipation protection of the integrated module 101 by the airflow in the guide cavity 203 flowing upward along the bottom of the integrated module 101.

[0037] like Figures 1 to 2 As shown, a pair of support base plates 202 are arranged at the bottom of the integrated module 101. The integrated module 101 is supported and limited by the pair of support base plates 202.

[0038] like Figures 1 to 2 As shown, each of the pair of support base plates 202 has multiple evenly distributed through holes 206, which are matched with the airflow direction of the cooling fan 204. The airflow generated by the cooling fan 204 during operation is transported and circulated through the multiple through holes 206.

[0039] like Figure 1 As shown, the housing 1, the supporting positioning ring 201 and the integrated module 101 cooperate to form a flow guiding cavity 203. Cooling fans 204 are fixedly installed on both sides of the housing 1, and the cooling fans 204 are connected to the flow guiding cavity 203.

[0040] It is worth noting that the air inlet of the cooling fan 204 is located on the outside of the casing 1, and the air outlet of the cooling fan 204 is located inside the air guide cavity 203.

[0041] like Figures 1 to 2 As shown, dust filters 207 are fixedly mounted on both sides of the cooling fan 204. The dust filters 207 provide dust protection for the cooling fan 204.

[0042] like Figures 1 to 5 As shown, a support and positioning frame 208 is provided at the bottom of the integrated module 101. The support and positioning frame 208 consists of a base plate 2081 and a side plate 2082. The base plate 2081 is located at the bottom of the integrated module 101, and the side plate 2082 is fitted onto the outside of the integrated module 101. The bottom of the integrated module 101 is supported and limited by the cooperation between the base plate 2081 and the side plate 2082.

[0043] like Figures 1 to 5 As shown, multiple evenly distributed connecting and fixing posts 209 are arranged between the support and positioning frame 208 and the housing 1. The two ends of the connecting and fixing posts 209 are connected to the inner wall of the housing 1 and the outer wall of the side plate 2082, respectively. The support and positioning frame 208 and the housing 1 are connected by multiple connecting and fixing posts 209, thereby ensuring the stability of supporting and fixing the housing 1.

[0044] like Figures 1 to 3As shown, the conductive heat dissipation mechanism 3 is fixedly mounted on the bottom of the integrated module 101. The conductive heat dissipation mechanism 3 includes a heat-conducting plate 301, which is fixedly mounted between a pair of supporting base plates 202. The heat-conducting plate 301 provides auxiliary support and heat conduction for the integrated module 101.

[0045] like Figures 1 to 3 As shown, multiple evenly distributed heat dissipation fins 302 are fixedly mounted below the heat-conducting plate 301, and all the heat dissipation fins 302 penetrate the casing 1. The multiple heat dissipation fins 302 play a role in conducting heat dissipation for the heat-conducting plate 301.

[0046] Specifically, the heat-conducting plate 301 and the multiple heat dissipation fins 302 are all hollow, and the multiple heat dissipation fins 302 are all in communication with the heat-conducting plate 301. This facilitates the flow of heat exchange fluid 303 within the heat-conducting plate 301 and the multiple heat dissipation fins 302, thereby facilitating auxiliary heat dissipation for the integrated module 101.

[0047] It is worth noting that the length of the heat dissipation fins 302 outside the casing 1 is less than the height of the support column 103. This reduces the direct contact between the heat dissipation fins 302 and the support platform, ensuring the effective support and positioning of the casing 1 by the support column 103.

[0048] like Figures 1 to 3 As shown, the heat-conducting plate 301 and the multiple heat dissipation fins 302 are all filled with heat exchange fluid 303. The heat exchange fluid 303 absorbs heat from the integrated module 101, thereby facilitating auxiliary heat dissipation for the integrated module 101.

[0049] In practical use, when the integrated module 101 is used to maintain the charging pile, the operation of a pair of cooling fans 204 can be controlled to allow outside air to be transported along the cooling fans 204 into the guide cavity 203. During the operation of the cooling fans 204, dust can be filtered through the dust filter 207.

[0050] The airflow generated during the operation of the cooling fan 204 can circulate within the guide cavity 203, thereby cooling the integrated module 101 by accelerating the airflow speed outside the integrated module 101. Simultaneously, the heat-conducting plate 301, the heat dissipation fins 302, and the heat exchange fluid 303 work together to further support and conduct heat dissipation of the integrated module 101, ensuring effective heat dissipation protection for the integrated module 101.

[0051] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0052] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
