Description

[0002] With the development of new energy electric vehicle technology, the requirements for charging performance are becoming increasingly stringent, making charging bases a crucial component of new energy electric vehicles. The temperature rise characteristics of charging bases are a vital performance parameter. During charging, the temperature at the charging base terminals increases continuously with charging time, eventually reaching a dynamic equilibrium. Without precise temperature monitoring and control, the safety of the charging base will be directly compromised.

[0003] Currently, the thermal management structure of charging bases in new energy electric vehicles involves drilling holes in a plastic part, inserting a temperature sensor, and then applying adhesive to achieve temperature conduction. However, during charging, the temperature is transferred to the temperature sensor through the plastic part and the adhesive, resulting in low temperature sensing accuracy. Utility Model Content

Figures 1 to 7 This application provides a charging dock 100, which includes: a housing 110, a circuit board 120, a charging terminal 130, a temperature sensor 140, and a heat-conducting component 150.

[0034] Specifically, the housing 110 has a receiving cavity 111; the circuit board 120 is disposed in the receiving cavity 111; the charging terminal 130 is disposed in the receiving cavity 111 and is connected to the circuit board 120; the temperature sensor 140 is disposed on the circuit board 120 and is electrically connected to the circuit board 120; the heat-conducting element 150 is disposed on the outer surface of the circuit board 120 and covers the temperature sensor 140, and the heat-conducting element 150 is thermally connected to the charging terminal 130 and the temperature sensor 140 respectively.

[0035] The housing 110 may be made of plastic injection molding, but is not limited to this.

[0036] The charging terminal 130 may be made of any one of copper alloy, tin alloy and brass, but is not limited to this.

[0037] The temperature sensor 140 can be either a resistance temperature detector or a semiconductor temperature sensor, but is not limited to these.

[0038] The heat-conducting component 150 may be made of any one of boron nitride, aluminum oxide, aluminum nitride, silicon carbide or graphene, but is not limited to this.

[0039] Understandably, when the charging dock 100 is working normally, the temperature of the charging terminal 130 will increase continuously as the charging time increases. The heat generated by the charging terminal 130 is conducted to the heat conductor 150, and then conducted to the temperature sensor 140 by the heat conductor 150 for monitoring.

[0040] In this application, a heat-conducting component 150 is used to thermally connect the charging terminal 130 and the temperature sensor 140, forming a heat-conducting structure of charging terminal 130-heat-conducting component 150-temperature sensor 140. This allows the heat generated by the charging terminal 130 to be directly conducted to the temperature sensor 140 through the heat-conducting component 150, improving the temperature sensing accuracy of the charging base 100 and ensuring that the temperature sensor 140 can efficiently monitor the temperature changes of the charging base 100 during charging, thereby improving the safety performance of the charging base 100. At the same time, this application has a simple structure, is easy to install, and reduces production costs.

[0041] In some embodiments, refer to Figures 1 to 3 The housing 110 includes a first housing portion 112 and a second housing portion 113, which together form a receiving cavity 111 to facilitate the overall assembly of the charging base 100 and improve the assembly efficiency of the charging base 100.

[0042] In some embodiments, the charging dock 100 has a first direction Z, a second direction X, and a third direction Y that intersect each other; for example, the charging dock 100 has a first direction Z, a second direction X, and a third direction Y that are perpendicular to each other. Here, "perpendicular" refers to a state where the angle formed by two lines, a line and a surface, or a surface is 89° to 91°.

[0043] Specifically, refer to Figure 3 The charging terminal 130 includes a first connecting part 131 and a second connecting part 132 that are connected to each other. The first connecting part 131 and the second connecting part 132 are arranged sequentially in the first direction Z, and the first connecting part 131 is arranged close to the circuit board 120 relative to the second connecting part 132. The first connecting part 131 is thermally connected to the heat-conducting component 150.

[0044] The first connecting portion 131 and the second connecting portion 132 can be integrally formed, meaning they are a single, integrated structure. Alternatively, the first connecting portion 131 can be separately disposed from the second connecting portion 132, with a fixed connection between them. For example, the second connecting portion 132 can be fixedly connected to the first connecting portion 131 through riveting, welding, or other processes. This application does not impose specific limitations and can be configured according to actual circumstances. For example, in this application, the first connecting portion 131 can also be separately disposed from the second connecting portion 132, with a fixed connection between them.

[0045] Understandably, when the charging dock 100 is working normally, the temperature of the charging terminal 130 will increase continuously as the charging time increases. The heat generated by the charging terminal 130 is conducted to the heat conductor 150 through the first connection part 131, and then conducted to the temperature sensor 140 by the heat conductor 150, so as to be monitored by the temperature sensor 140. This improves the temperature sensing accuracy of the charging dock 100, ensures that the temperature sensor 140 can efficiently monitor the temperature changes of the charging dock 100 during charging, and improves the safety performance of the charging dock 100.

[0046] In some embodiments, refer to Figures 3 to 4 The heat-conducting component 150 extends along the second direction X; the circuit board 120 has a receiving groove 121 on one side of the second direction X, and the first connecting part 131 is disposed in the receiving groove 121 to limit the charging terminal 130, ensure the stability of the overall structure of the charging base 100, further ensure the safety performance of the charging base 100, and at the same time ensure the compactness of the overall structure of the charging base 100 and reduce the space occupied by the charging base 100.

[0047] In some embodiments, refer to Figures 3 to 4 Multiple charging terminals 130 are provided, and the multiple charging terminals 130 are arranged along the second direction X; multiple receiving slots 121 are provided, and each receiving slot 121 is respectively provided on both sides of the circuit board 120 in the second direction X, and each first connecting part 131 is respectively provided in a corresponding receiving slot 121 to limit the multiple charging terminals 130, further ensuring the stability of the overall structure of the charging base 100, further ensuring the safety performance of the charging base 100; at the same time, it ensures the compactness of the overall structure of the charging base 100 and reduces the space occupied by the charging base 100.

[0048] In some embodiments, refer to Figures 3 to 7 Multiple temperature sensors 140 are provided, and the multiple temperature sensors 140 are arranged along the second direction X.

Each temperature sensor 140 is thermally connected to the heat-conducting component 150, and each temperature sensor 140 is disposed on the side of a corresponding first connection part 131.

[0049] This application sets up multiple temperature sensors 140 to monitor the temperature of a corresponding charging terminal 130, thereby improving the temperature sensing accuracy of the charging dock 100, ensuring that the temperature sensors 140 can efficiently monitor the temperature changes of the charging dock 100 during charging, and improving the safety performance of the charging dock 100.

[0050] In some embodiments, refer to Figures 4 to 7The heat-conducting component 150 includes a fixing part 151 and a heat-conducting part 152 connected to each other. The fixing part 151 is disposed close to the circuit board 120 relative to the heat-conducting part 152. The fixing part 151 is fixedly connected to the circuit board 120 to achieve the positioning and fixation of the heat-conducting component 150, further ensuring the stability of the overall structure of the charging dock 100 and further ensuring the safety performance of the charging dock 100. The heat-conducting part 152 covers the temperature sensor 140 and is disposed between two adjacent first connecting parts 131. The heat-conducting part 152 is thermally connected to the first connecting part 131 and the temperature sensor 140 respectively, so as to realize the direct conduction of heat between the charging terminal 130 and the temperature sensor 140, improve the temperature sensing accuracy of the charging dock 100, ensure that the temperature sensor 140 efficiently monitors the temperature change of the charging dock 100 during charging, and improve the safety performance of the charging dock 100.

[0051] The fixing part 151 and the heat-conducting part 152 can be integrally formed, that is, the fixing part 151 and the heat-conducting part 152 are a single structure. Alternatively, the fixing part 151 and the heat-conducting part 152 can be separately arranged and fixedly connected, for example, the fixing part 151 can be fixedly connected to the heat-conducting part 152 by bonding, riveting, or other processes. This application does not impose specific limitations, and the specific configuration can be determined according to the actual situation.

[0052] In some embodiments, refer to Figures 4 to 7 The fixing part 151 has a fixing groove 1511 on the side near the circuit board 120.

[0053] For example, the dimension of the circuit board 120 in the second direction X is larger than the dimension of the fixing groove 1511 in the second direction X, so as to ensure that the circuit board 120 and the fixing groove 1511 are interference fit, and to ensure that the heat-conducting component 150 and the circuit board 120 are firmly connected.
