Therefore, they should not be construed as limitations on this utility model.

[0026] The terms “first,” “second,” “third,” etc., are used merely to distinguish elements with similar attributes, not to indicate or imply relative importance or a specific order.

[0027] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.

[0028] Within a battery swapping station, wiring harnesses between various loads (such as cooling systems and video surveillance systems) and power distribution terminals (such as electrical control cabinets and distribution cabinets) are typically connected via transition structures (such as connectors) to enable power and signal transmission. However, current technology does not strictly differentiate between these transition structures. On the one hand, this makes it easy to misconnect, leading to short circuits or equipment damage. On the other hand, it is prone to electromagnetic interference, compromising the safety and reliability of power and signal transmission.

[0029] To solve at least one of the above technical problems, it is necessary to improve or optimize the structure of the existing technology.

[0030] Example 1 Please see Figure 1 , Figure 2 and Figure 3 An embodiment of the first aspect of this utility model provides a wire harness adapter. The wire harness adapter 100 includes an adapter mounting plate 10, a high-voltage power adapter 20, a low-voltage communication adapter 30, and a low-voltage power communication adapter 40, wherein the high-voltage power adapter 20, the low-voltage communication adapter 30, and the low-voltage power communication adapter 40 are mounted on the adapter mounting plate 10. It is worth noting that, as used herein and hereinafter, high voltage refers to a voltage greater than 60V, such as 220V or 380V, and low voltage refers to a voltage less than or equal to 60V, such as 3V or 12V.

[0031] It should be noted that, to facilitate the differentiation of adapters with different operating voltage ranges, the adapter mounting plate 10 includes an independent high-voltage zone 13 and a low-voltage zone 14. The high-voltage zone 13 is used to house the high-voltage power adapter 20, and the low-voltage zone 14 is used to house the low-voltage communication adapter 30 and the low-voltage power communication adapter 40. Preferably, the distance between the high-voltage zone 13 and the low-voltage zone 14 is greater than or equal to 40mm, such as 40mm, 50mm, or 60mm.

[0032] For example, such as Figure 2As shown, the adapter mounting plate 10 is used to separate the wiring harness between the power distribution end and the load end of the battery swapping station into two parts. It is worth noting that the power distribution end refers to equipment used for power distribution, signal control, and circuit protection, such as electrical control cabinets, distribution cabinets, and other final-level power distribution equipment. The load end includes, but is not limited to, the cooling system and video surveillance system of the battery swapping station. The wiring harnesses include, but are not limited to, high-voltage power harnesses, low-voltage communication harnesses, and low-voltage power communication harnesses, and each of these harnesses includes a compatible connector (such as a plug) for connection. For example, the high-voltage power harness includes a high-voltage connector, the low-voltage communication harness includes a low-voltage communication connector, and the low-voltage power communication harness includes a low-voltage power communication connector, etc., to facilitate quick connection of the wiring harnesses separated into two parts by the adapter mounting plate 10.

[0033] Specifically, the adapter mounting plate 10 is elongated and includes a base plate 11 and a side plate 12, wherein the bottom of the side plate 12 is connected to or integrally formed with the base plate 10. Preferably, the side plate 12 is perpendicularly connected to the base plate 10. It should be noted that the base plate 11 is used to fix the adapter mounting plate 10 with fasteners, such as fixing it on the gantry frame (gantry-type swapping frame between two swapping compartments in the swapping station); the side plate 12 is provided with a high-voltage zone 13 and a low-voltage zone 14, and the high-voltage zone 13 and the low-voltage zone 14 each extend along the length direction of the side plate 12.

[0034] For example, to enable the installation of the high-voltage power adapter 20, the low-voltage communication adapter 30, and the low-voltage power-communication adapter 40 on the adapter mounting plate 10, the high-voltage zone 13 has a first mounting port 15, and the low-voltage zone 14 has a second mounting port 16 and a third mounting port 17. The first mounting port 15 is used to install the high-voltage power adapter 20, the second mounting port 16 is used to install the low-voltage communication adapter 30, and the third mounting port 17 is used to install the low-voltage power-communication adapter 40. Furthermore, the shape of the first mounting port 15 is adapted to the outer contour of the high-voltage power adapter 20, the shape of the second mounting port 16 is adapted to the outer contour of the low-voltage communication adapter 30, and the shape of the third mounting port 17 is adapted to the outer contour of the low-voltage power-communication adapter 40. In this first embodiment, the first mounting port 15 is circular, the second mounting port 16 is also circular, and the third mounting port 17 is rectangular, but this is not a limitation.

[0035] To enable power and signal transmission between the power distribution terminal and each load, in some embodiments, the number of first mounting ports 15, second mounting ports 16, and third mounting ports 17 are each multiple. In this first embodiment, there are four first mounting ports 15, six second mounting ports 16, and six third mounting ports 17, to meet the design requirements of each battery swapping compartment.

[0036] For example, such as Figure 2 , Figure 4 As shown, the high-voltage power adapter 20 is used to connect the high-voltage power output harness at the distribution end to the high-voltage power input harness at the load end. Specifically, the high-voltage power adapter 20 is installed in the high-voltage zone 13 and includes a first adapter body 21, a first snap-fit ​​portion 22, and a first fixing portion 23. One end of the first adapter body 21 is used to connect to the high-voltage power output harness at the distribution end, and the other end has the first snap-fit ​​portion 22, which is used to connect to the high-voltage power input harness at the load end. The first fixing portion 23 is formed on the outer wall of the first adapter body 21 and is used to connect to the side plate 12 of the adapter mounting plate 10.

[0037] Furthermore, the end of the first adapter body 21 that is used to connect to the high-voltage power output harness of the power distribution end has an external thread, which is adapted to the internal thread of the high-voltage connector of the high-voltage power output harness of the power distribution end. This facilitates the connection of one end of the high-voltage power adapter 20 to the high-voltage power output harness of the power distribution end through a threaded connection.

[0038] It should be noted that, to ensure connection stability, in some embodiments, the number of first latching portions 22 is multiple. In this first embodiment, the number of first latching portions 22 is three. These three first latching portions 22 are distributed circumferentially at the other end of the first adapter body 21, and each first latching portion 22 protrudes from the outer wall of the first adapter body 21, such as in the shape of a convex column. Preferably, these three first latching portions 22 are arranged in a triangular shape on the outer wall of the first adapter body 21, such as an isosceles triangle or an equilateral triangle.

[0039] Furthermore, to prevent mis-connection, the high-voltage power adapter 20 also includes a positioning part 24 for positioning the high-voltage power input harness at the load end on the high-voltage power adapter 20. Specifically, the positioning part 24 is groove-shaped, formed at the other end of the first adapter body 21 where the first latching part 22 is provided, and extends axially along the columnar first adapter body 21. It should be noted that the shape of the positioning part 24 depends on the shape of the high-voltage connector of the high-voltage power input harness at the load end, and is not limited to a groove shape. Thus, before the high-voltage power input harness at the load end is connected to the high-voltage power adapter 20, the high-voltage power adapter 20 contacts the high-voltage connector of the high-voltage power input harness at the load end through the positioning part 24. This helps to ensure the accuracy of the connection position and direction of the two, thereby preventing mis-connection.

[0040] For example, such as Figure 5As shown, the low-voltage communication adapter 30 is used to connect the low-voltage communication control harness at the power distribution end to the low-voltage communication receiving harness at the load end. Specifically, the low-voltage communication adapter 30 includes a second adapter body 31, a second latching portion 32, and a second fixing portion 33. Each end of the second adapter body 31 has a second latching portion 32, which is used to connect to the low-voltage communication control harness at the power distribution end and the low-voltage communication receiving harness at the load end, respectively. The second fixing portion 33 is formed on the outer wall of the second adapter body 31 and is used to connect to the side plate 12 of the adapter mounting plate 10.

[0041] It should be noted that, to ensure connection stability, in some embodiments, the number of second latching portions 32 is multiple. In this first embodiment, the number of second latching portions 32 is six. Three of these six second latching portions 32 are distributed circumferentially at one end of the second adapter body 31, and the other three are distributed circumferentially at the other end of the second adapter body 31. Furthermore, each second latching portion 32 protrudes from the outer wall of the second adapter body 31, such as in the shape of a convex column. Preferably, the three first latching portions 22 at each end of the second adapter body 31 are arranged in a triangular pattern on the outer wall of the first adapter body 21, such as an isosceles triangle or an equilateral triangle. In this way, by providing three mounting points arranged in a triangular pattern at each of the opposite ends of the low-voltage communication adapter 30, the connection stability between the low-voltage communication adapter 30 and the low-voltage communication control harness at the power distribution end and the low-voltage communication receiving harness at the load end can be ensured.

[0042] For example, such as Figure 6 As shown, the low-voltage power communication adapter 40 is used to connect the low-voltage power communication output harness at the power distribution end to the low-voltage power communication input harness at the load end. Specifically, the low-voltage power communication adapter 40 includes a third adapter body 41, a third latching part 42, and a third fixing part 43. One end of the third adapter body 41 is used to connect to the low-voltage power communication output harness at the power distribution end, and the other end has the third latching part 42, which is used to connect to the low-voltage power communication input harness at the load end. The third fixing part 43 is formed on the outer wall of the third adapter body 41 and is used to connect to the side plate 12 of the adapter mounting plate 10.

[0043] It should be noted that, to ensure connection stability, in some embodiments, there are multiple third latching portions 42. In this first embodiment, there are two third latching portions 42. These two third latching portions 42 are distributed circumferentially at the other end of the third adapter body 41, and each third latching portion 42 protrudes from the outer wall of the third adapter body 41, such as a wedge-shaped protrusion. Preferably, the two third latching portions 42 are disposed opposite to each other on the outer wall of the third adapter body 41.

[0044] like Figure 3 As shown, it should be noted that, in order to achieve connection and facilitate differentiation between adapters with different operating voltage ranges, the cross-sectional shapes of the interfaces of the high-voltage power adapter 20, low-voltage communication adapter 30, and low-voltage power communication adapter 40 are different. For example, the high-voltage power adapter 20 has a high-voltage interface 25 that penetrates the first adapter body 21, and the cross-section of the high-voltage interface 25 is circular; and / or, the low-voltage communication adapter 30 has a low-voltage communication interface 34 that penetrates the second adapter body 31, and the cross-section of the low-voltage communication interface 34 is convex; and / or, the low-voltage power communication adapter 40 has a low-voltage power communication interface 44 that penetrates the third adapter body 41, and the cross-section of the low-voltage power communication interface 44 is rectangular, but not limited to these. This facilitates the prevention of incorrect connection between the wire harness and the adapter through differentiated interface shapes.

[0045] Furthermore, the wiring harness adapter 100 also includes a high-voltage label 50 and a low-voltage label 60. The high-voltage label 50 is affixed to the high-voltage area 13 to indicate its location; the low-voltage label 60 is affixed to the low-voltage area 14 to indicate its location. For example, an orange high-voltage label 50 indicates that the area where the high-voltage label 50 is located is the high-voltage area 13; a blue low-voltage label 60 indicates that the area where the low-voltage label 60 is located is the low-voltage area 14. This allows for a direct visual determination of the operating voltage range of the adapter, such as high voltage or low voltage, based on the color difference.

[0046] Furthermore, such as Figure 2 As shown, the wire harness adapter 100 also includes a wiring rod 70 for fixing the wire harness. Specifically, the wiring rod 70 is disposed on the side of the side plate 12 near the power distribution end and is fixedly connected to the side plate 12.

[0047] Furthermore, to achieve connection, the wire harness adapter 100 also includes an adapter fastener 80 and a mounting plate fastener 90. The adapter fastener 80 connects the high-voltage power adapter 20, low-voltage communication adapter 30, and low-voltage power communication adapter 40 to the side plate 12 of the adapter mounting plate 10. The mounting plate fastener 90 connects the base plate 11 of the adapter mounting plate 10 to the gantry of the power swapping station. Correspondingly, the high-voltage power adapter 20, low-voltage communication adapter 30, low-voltage power communication adapter 40, and adapter mounting plate 10 each have mounting holes corresponding to and adapted to the adapter fastener 80, and the adapter mounting plate 10 and the gantry each have connection holes corresponding to and adapted to the mounting plate fastener 90. This ensures the connection stability of the wire harness adapter 100.

[0048] In summary, compared to existing technologies, this wiring harness adapter 100 provides an adapter mounting plate 10 with independent high-voltage zones 13 and low-voltage zones 14 between the power distribution end and the load end of the power swapping station. A high-voltage power adapter 20 is installed in the high-voltage zone 13, and a low-voltage communication adapter 30 and a low-voltage power communication adapter 40 are installed in the low-voltage zone 14. Furthermore, the cross-sectional shapes of the interfaces of the high-voltage power adapter 20, the low-voltage communication adapter 30, and the low-voltage power communication adapter 40 are different. This facilitates the differentiation of different applications. As a voltage range adapter, it prevents mis-connection and short circuits or equipment damage caused by mis-connection. On the other hand, since the adapters for different operating voltage ranges are separated, it can reduce the electromagnetic interference between the high-voltage power supply line where the high-voltage power supply adapter 20 is located and the low-voltage communication line where the low-voltage communication adapter 30 and the low-voltage power supply communication adapter 40 are located, thus solving the problem of communication instability caused by electromagnetic interference and improving the safety and reliability of power transmission and signal transmission.

[0050] Example 3 A third aspect of this utility model provides a battery swapping station that includes a wiring harness system as described in Embodiment 2, which is beneficial to giving the battery swapping station higher safety and reliability.

[0051] 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 disclosed 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 appended claims.
