Description

TECHNICAL FIELD

[0001] The utility model relates to a charging seat and the charging seat assembly including this charging seat. BACKGROUND

[0002] In the prior art, in order to charge the battery pack of a new energy electric vehicle, a charging seat adapted to be matched with a charging gun needs to be installed on the new energy electric vehicle. In order to improve the charging speed, the charging current needs to be increased, and the current charging current is as high as 600A, and will even be increased to 1000A in the future. When a large current flows through the power terminal in the charging seat, a large amount of heat will be generated, which will cause the temperature of the power terminal in the charging seat to rise sharply. If the temperature rise cannot be controlled in time, it will cause a safety accident, for example, the charging seat or other electrical equipment will be burned out.

[0003] In the prior art, in order to control the temperature rise of the power terminal, a lead frame is usually arranged in the charging seat, and a temperature detection module is integrated on the lead frame. The temperature detection module includes a temperature sensor and a heat-conducting pad wrapped outside the temperature sensor. The heat-conducting pad is in thermal contact with the power terminal, and the temperature sensor is electrically connected with the lead frame. However, in the prior art, the lead frame is relatively large in size, and needs to be pre-installed in the charging seat shell, which is very inconvenient to use. In addition, in the prior art, in order to facilitate the installation of the lead frame, the charging seat shell needs to be designed in a split type, which leads to a complex structure of the charging seat shell. In addition, the existing lead frame needs to be able to rotate between a locking position for locking the power terminal and an unlocking position for unlocking the power terminal, which will cause the lead frame and the charging seat shell to be more complex, more difficult to assemble, and higher in cost.

[0053] The technical solutions of the present application will be further described in detail below with reference to the drawings. In the description, identical or similar reference numerals indicate identical or similar components. The following description of the embodiments of the present application with reference to the drawings is intended to explain the general inventive concept of the present application and should not be construed as a limitation of the present application.

[0054] In addition, in the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the present disclosure. However, it will be apparent to one skilled in the art that one or more embodiments can be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to simplify the drawings.

[0055] According to one general inventive concept, a charging base is provided. The charging base includes a charging base housing formed with a terminal receptacle and a slot communicating with the terminal receptacle; a terminal assembly including a power terminal and inserted into the terminal receptacle; and a temperature detection module inserted from an outside of the charging base housing into the slot for detecting a temperature of the power terminal. The temperature detection module includes a connector interface for mating with a connector on the outside of the charging base housing, and a limiting feature is formed on the charging base housing. When the temperature detection module is inserted into a predetermined mounting position, the limiting feature is in a position not interfering with a connector housing to allow the connector to mate with the connector interface. When the temperature detection module is not inserted into the predetermined mounting position, the limiting feature is in a position interfering with the connector housing so that the connector cannot mate with the connector interface.

[0056] According to another general inventive concept, a charging base assembly is provided. The charging base assembly includes the aforementioned charging base; and a connector mating with a connector interface of a temperature detection module of the charging base.

[0057] Figure 10A perspective view of a charging dock according to an exemplary embodiment of the present invention is shown; Figure 11 This diagram shows an exploded view of a charging dock according to an exemplary embodiment of the present invention. Figure 12 Showing an anatomical view of a charging dock according to an exemplary embodiment of the present invention; Figure 13 Showing an axial sectional view of a charging dock according to an exemplary embodiment of the present invention; Figure 14 A perspective view of a charging dock assembly according to an exemplary embodiment of the present invention is shown; Figure 15 An exploded view of a charging dock assembly according to an exemplary embodiment of the present invention is shown. Figure 16 This shows a cross-sectional view of a charging dock assembly according to an exemplary embodiment of the present invention, wherein the connector 8 has not yet been mated with the connector interface 120; Figure 17 This shows a cross-sectional view of a charging dock assembly according to an exemplary embodiment of the present invention, wherein connector 8 has been mated with connector interface 120; Figure 18 This shows a cross-sectional view of a charging dock assembly according to an exemplary embodiment of the present invention, wherein the temperature detection module 100 is not inserted into the predetermined installation position, and the limiting feature 68 prevents the connector 8 from mating with the connector interface 120.

[0058] like Figures 10 to 18 As shown, in an exemplary embodiment of this utility model, a charging dock is disclosed. The charging dock includes: a charging dock housing 6, a terminal assembly 5, and a temperature detection module 100. The charging dock housing 6 has a terminal socket 61 and a slot 62 communicating with the terminal socket 61. The terminal assembly 5 includes a power terminal 50 and is inserted into the terminal socket 61. The temperature detection module 100 is inserted from the outside of the charging dock housing 6 into the slot 62 for detecting the temperature of the power terminal 50. The temperature detection module 100 includes a connector interface 120 located outside the charging dock housing 6 for mating with a connector 8.

[0059] like Figures 10 to 18 As shown, in the illustrated embodiment, a limiting feature 68 is formed on the exterior of the charging base housing 6. When the temperature detection module 100 is inserted into the predetermined installation position, the limiting feature 68 is in a position that does not interfere with the connector housing 80, allowing the connector 8 to mate with the connector interface 120. When the temperature detection module 100 is not inserted into the predetermined installation position, the limiting feature 68 is in a position that interferes with the connector housing 80. Figure 18The positioning shown prevents the connector 8 from mating with the connector interface 120. Therefore, in the illustrated embodiment, the limiting feature 68 on the charging housing 6 will not obstruct the mating of the connector 8 with the connector interface 120 of the temperature detection module 100 only when the temperature detection module 100 is inserted into the predetermined installation position. Thus, this invention ensures that the temperature detection module 100 is inserted into the predetermined installation position.

[0060] like Figures 10 to 18 As shown in the illustrated embodiment, the limiting feature 68 is adapted to engage with the mating feature 88 on the connector housing 80. When the temperature detection module 100 is inserted into the predetermined installation position and the connector 8 is mated with the connector interface 120, the limiting feature 68 on the charging base housing 6 engages with the mating feature 88 on the connector housing 80, thereby engaging the connector housing 80 with the charging base housing 6. This allows the connector 8 and the connector interface 120 to withstand greater external forces without being damaged by them.

[0061] like Figures 10 to 18 As shown, in the illustrated embodiment, the limiting feature 68 on the charging base housing 6 is a raised tongue-shaped feature adapted to engage with a slot (i.e., the aforementioned mating feature 88) on the connector housing 80. However, the present invention is not limited to the illustrated embodiment; for example, the limiting feature 68 on the charging base housing 6 may be a raised column-shaped feature adapted to engage with a slot on the connector housing 80.

[0062] like Figures 10 to 18 As shown in the illustrated embodiment, when the temperature detection module 100 is inserted into the predetermined installation position, the limiting feature 68 is aligned with the mating feature 88 on the connector housing 80 to allow the connector 8 to mate with the connector interface 120. When the temperature detection module 100 is not inserted into the predetermined installation position, the limiting feature 68 is misaligned with the mating feature 88 on the connector housing 80, preventing the connector 8 from mating with the connector interface 120. Figure 18 As shown, when the temperature detection module 100 is not inserted into the predetermined installation position, the limiting feature 68 will abut against the front end face of the connector housing 80, preventing the connector 8 from mating with the connector interface 120.

[0065] like Figures 1 to 18 As shown, in the illustrated embodiment, the temperature detection module 100 is adapted to be pluggably mounted from the outside of the charging base housing 6 into a slot 62 on the charging base housing 6. The thermal pad 2 makes thermal contact with the power terminal 50 when the temperature detection module 100 is mounted into the slot 62, so as to transfer the heat of the power terminal 50 to the temperature sensor 3.

[0066] like Figures 1 to 18 As shown in the illustrated embodiment, if the temperature detection module 100 is not inserted into the aforementioned predetermined installation position, the thermal pad 2 and the power terminal 50 will not be in reliable thermal contact. To ensure reliable thermal contact between the thermal pad 2 and the power terminal 50, the temperature detection module 100 must be inserted into the aforementioned predetermined installation position.
