[0052] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0053] Figure 1The connector device 1 according to one embodiment of the present application is schematically shown. Figure 1 As shown, the connector device 1 includes a first connector 100 and a second connector 200. The first connector 100 is suitable for connecting or separating with the second connector 200. When the connector device 1 is used, the first connector 100 is arranged on one of the vehicle body and the battery pack and is connected to the corresponding liquid coolant assembly (not shown in the figure); accordingly, the second connector 200 is arranged on the other of the vehicle body and the battery pack and is connected to the corresponding liquid coolant assembly (not shown in the figure). After the first connector 100 and the second connector 200 are connected together (for example, when the battery pack is installed on the vehicle body), a closed liquid coolant circulation loop is formed; after the first connector 100 and the second connector 200 are separated (for example, when the battery pack is removed from the vehicle body), the liquid coolant circulation loop is disconnected. For simplicity, in this application, the connector device 1 of the present application is described by taking the first connector 100 as installed on the battery pack and the second connector 200 as installed on the vehicle body as an example.

[0054] like Figure 3 As shown, the first connector 100 includes a first substrate 102 and two first connectors 224 mounted on the first substrate 102. Specifically, the first substrate 102 has a first end face 205 and a second end face 206 opposite to the first end face 205. Two mounting holes 204 are configured on the first substrate 102, and each mounting hole 204 extends from the first end face 205 to the second end face 206. The two first connectors 224 are respectively mounted in the corresponding mounting holes 204. The two first connectors 224 are respectively used to form a liquid coolant return channel and a liquid coolant outflow channel to facilitate the use of the user. As also shown in FIG. Figure 3 As shown, in the present application, the first substrate 102 is substantially parallel to the XY plane in the XYZ three-dimensional rectangular coordinate system; the central axis of the mounting hole 204 is substantially parallel to the Z direction in the XYZ three-dimensional rectangular coordinate system.

[0055] like Figure 4 As shown, the second connector 200 includes a second substrate 201 and two second connectors 210 mounted on the second substrate 201. The two first connectors 224 are adapted to be connected to the corresponding second connectors 210 to connect the first connector 100 and the second connector 200 together. Of course, the first connector 224 can also be separated from the second connector 210 to separate the first connector 100 from the second connector 200.

[0056] like Figure 6 and Figure 7As shown, the first joint 224 includes a first valve housing 2248. The first valve housing 2248 includes a fitting section 2249 and a first connecting section 2241 and a second connecting section 2242 axially located on both sides of the fitting section 2249. After the first joint 224 is mounted on the first substrate 102, the fitting section 2249 is located in the mounting hole 204, and the first connecting section 2241 and the second connecting section 2242 are located on both sides of the first substrate 102. The first connecting section 2241 is suitable for connecting or separating with the corresponding second joint 210 to connect or separate the first connector 100 and the second connector 200. An elastic first sealing ring 301 is arranged between the fitting section 2249 and the inner surface 2041 of the mounting hole 204. The elastic first sealing ring 301 can be compressed along the radial direction of the mounting hole 204. For example, when the first connector 100 and the second connector 200 are connected together, if the two first connection sections 2241 (or the two first joints 224) are not aligned with the two second joints 210 (for example, the distance between the central axes of the two first connection sections 2241 is not equal to the distance between the central axes of the two second joints 210), the first sealing ring 301 can adapt to the radial displacement movement of the matching section 2249 (or the first joint 224) along the mounting hole 204. In other words, during the radial displacement of the first joint 224, the first sealing ring 301 is compressed to a certain extent, and at the same time, it elastically supports the first joint 224, so that the first connection sections 2241 of the two first joints 224 are adjusted to be aligned with the two second joints 210 respectively, and then the first connector 100 and the second connector 200 can be smoothly connected together. At the same time, the first sealing ring 301 also seals the gap between the matching section 2249 and the mounting hole 204. Since the first connecting section 2241 of the first valve housing 2248 extends out of the battery pack housing 4, the first substrate 102 is located inside the battery pack housing 4 (eg, Figure 6 As shown in FIG. 2 , the first sealing ring 301 can prevent pollutants in the external environment from entering the battery pack through the gap between each matching section 2249 and the corresponding mounting hole 204. When driving in water, the first sealing ring 301 can also prevent water from entering the battery pack, thereby ensuring the safety of the battery pack and the vehicle.

[0057] It can be seen that the first sealing ring 301 not only has the sealing function of preventing water and pollutants, but also can adapt to the radial offset movement of the matching section 2249 (or the first valve housing 2248) along the mounting hole 204.

[0058] For example, in some early connector devices, a structure (usually a spring or an elastic bushing) specifically used to respond to the offset movement of the first joint and / or the second joint is not provided on the first connector and / or the second connector. When the first connector of such early connector devices needs to be replaced, the first joint of the replacement first connector provided may not be exactly the same as the first joint of the first connector of the early connector device, resulting in the first joint of the replacement first connector and the second joint of the second connector of the early connector device being unable to be precisely aligned, thereby causing the replacement first connector and the second connector of the early connector device to be unable to connect or the reliability and stability of the connector device after maintenance to be adversely affected. The two first joints 224 of the first connector 100 of the present application can be adjusted to be precisely aligned with the two second joints of the second connector, respectively, so that the use of the first connector 100 of the present application helps to improve the reliability and stability of the connector device after maintenance.

[0059] In addition, there are also some connector devices that do not require a structure specifically for responding to the displacement movement of the first connector and / or the second connector in their original products due to their high structural precision (for example, connector devices made of metal). However, during the subsequent maintenance of the connector device, when a replacement first connector is used, the above-mentioned connection problem will also occur. In the first connector 100 of the present application, each first sealing ring 301 provides appropriate radial displacement movement capability for the corresponding first connector 224, so the first connector 100 of the present application can be smoothly and accurately assembled with the second connector of the above-mentioned connector device.

[0060] In one embodiment, the cross-sectional diameter of the first sealing ring 301 may be between 3 mm and 6 mm. Such a first sealing ring 301 can well adapt to the radial displacement movement of the corresponding first joint 224, and play a good elastic supporting role for the first joint 224 when the first joint 224 is radially displaced. Of course, the first sealing ring 301 may also be configured to have other cross-sectional diameter sizes, which are not limited here.

[0061] In another embodiment, the first sealing ring 301 may be made of EPDM rubber (ie, ethylene propylene diene monomer rubber), and of course, may also be made of other elastic rubbers.

[0062] Also like Figure 6 As shown, the first connecting section 2241 is configured with a shoulder 2243 extending radially outward, and the shoulder 2243 abuts against the second end surface 206 of the first substrate 102. The second connecting section 2242 is configured with a rib 2247 extending radially outward. At least a portion of the rib 2247 is located in the mounting hole 204, and the rib 2247 is radially spaced apart from the inner surface 2041 of the mounting hole 204 (e.g., Figure 8 ). A groove is formed between the rib 2247 and the shoulder 2243, and the first sealing ring 301 is located in the groove, that is, between the rib 2247 and the shoulder 2243. According to this structure, the rib 2247 and the shoulder 2243 limit the first sealing ring 301 along the axial direction of the first valve housing 2248, so as to prevent the first sealing ring 301 from moving away from the mounting hole 204 when the first connector 100 is connected to the second connector 200.

[0063] The radial clearance between the rib 2247 and the inner surface 2041 of the mounting hole 204 provides a movement space for the radial displacement movement of the first valve housing 2248 (or the first joint 224). In one embodiment, the radial clearance between the rib 2247 and the inner surface 2041 of the second mounting hole 204 is between 0.2 mm and 0.5 mm.

[0064] like Figure 6 As shown, the first connector 100 further includes a pipe 223. The pipe 223 is provided with a flange 2233 extending radially outward. Figure 6 As shown, when the first connector 224 is mounted on the first substrate 102, the second connecting section 2242 extends through the mounting hole 204 and is connected to the connecting pipe 223, and the flange 2233 abuts against the first end face 205 of the first substrate 102; at the same time, the shoulder 2243 abuts against the second end face 206 of the first substrate 102. In this way, in the first connector 100, the connecting pipe 223, the first connector 224 and the first substrate 102 are mutually constrained and assembled together along the Z direction through their own structures (for example, through the mounting hole 204, the flange 2233 and the shoulder 2243), without the need for additional fixings. As a result, the number of parts of the first connector 100 is reduced, which reduces the cost of the first connector 100 (and the connector device 1), and also facilitates the assembly of the first connector 100.

[0065] like Fig. 9 As shown, the connecting pipe 223 is configured with a connecting groove 2231. At least a portion of the second connecting section 2242 is inserted into the connecting groove 2231. In this way, at least a portion of the second connecting section 2242 is sleeved together with the connecting pipe 223, which helps to improve the connection stability of the two.

[0066] Also like Fig. 9 As shown, the connection groove 2231 includes a circumferential side wall 2234 , and the flange 2233 is located at the end of the circumferential side wall 2234 facing the first substrate 102 .

[0067] The pipe 223 includes an opening 2235 formed on a circumferential side wall 2234 and an elastic sheet 2232 in the opening 2235. The elastic sheet 2232 extends from an edge portion of the opening 2235 close to the flange 2233 to the inside of the opening 2235 and is separated from the remaining edge portion of the opening 2235. Figure 7 As shown, a protrusion 2244 protruding radially outward is configured on the second connecting section 2242. The protrusion 2244 is adapted to fit into the opening 2235 and engage with the elastic sheet 2232. According to this structure, the elastic sheet 2232 stably holds the protrusion 2244 in the opening 2235, so that the connecting pipe 223 and the first joint 224 are stably connected together without the need for additional fixing members. In other embodiments, the connecting pipe 223 and the second connecting section 2242 (or the first joint 224) can also be threadedly connected.

[0068] Also like Figure 6 As shown, the first joint 224 also includes a first valve core assembly 213 in the first valve housing 2248. The first valve core assembly 213 includes a first valve plug 2131 and a first elastic member 2133. The first valve plug 2131 is suitable for sealing contact or separation with the inner surface of the first connecting section 2241. The two ends of the first elastic member 2133 abut against the first valve plug 2131 and the connecting pipe 223 respectively, so that the first valve housing 2248 and the first valve plug 2131 can axially reciprocate relative to each other.

[0069] In one embodiment, Figure 2 and Figure 4 As shown, the second joint 210 includes a second valve housing 2015, a sleeve 2031 disposed in the second valve housing 2015, a second valve plug 2032 disposed in the sleeve 2031, and a second elastic member 2033. The second valve plug 2032 is adapted to be in sealing contact with or separated from the inner surface of the sleeve 2031. Both ends of the second elastic member 2033 abut against the sleeve 2031 and the second valve plug 2032, respectively, so that the sleeve 2031 can axially reciprocate relative to the second valve housing 2015 and the sleeve 2031.

[0070] like Figure 2As shown, when the first connector 224 is connected to the second connector 210, the first valve plug 2131 abuts against the second valve plug 2032, and the first connecting section 2241 of the first valve housing 2248 abuts against the sleeve 2031. The first valve housing 2248 moves in the direction from the second connecting section 2242 to the first connecting section 2241 (i.e., generally in the direction of the second connector 200 along the Z direction) and pushes the sleeve 2031 to move. As a result, the first valve plug 2131 is separated from the inner surface of the first connecting section 2241, and the first connector 100 is turned on (at this time, the first elastic member 2133 is compressed); the second valve plug 2032 is also separated from the inner surface of the sleeve 2031, and the second connector 200 is turned on (at this time, the second elastic member 2033 is compressed). In this way, the connector assembly 1 is turned on and forms a closed liquid coolant circulation loop, and the liquid coolant can flow through the connector assembly 1.

[0071] When the first connector 224 is separated from the second connector 210, the first elastic member 2133 recovers and drives the first valve housing 2248 to return to the inner surface of the first connecting section 2241 of the first valve housing 2248 to seal contact with the first valve plug 2131, and the first connector 100 is cut off. The second elastic member 2033 recovers and drives the sleeve 2031 to return to seal contact with the second valve plug 2032, and the second connector 200 is cut off. In this way, the liquid coolant circulation loop is disconnected, and the liquid coolant will not leak from the first connector 100 or the second connector 200. Therefore, by using the connector device 1 of the present application, when replacing the battery pack of the vehicle, the liquid coolant circulation loop can be quickly disconnected and connected, which helps to improve the replacement efficiency of the battery pack.

[0072] Also like Figure 6 As shown, the inner surface of the end of the first connecting section 2241 away from the second connecting section 2242 is configured as a slope 2246 that is inclined radially inward. Overall, the end of the first connecting section 2241 forms a constricted shape. A second sealing ring 302 is provided between the first valve plug 2131 and the slope 2246. According to this structure, when the first valve plug 2131 and the first valve housing 2248 move relative to each other, the second sealing ring 302 brings less resistance to the first valve plug 2131 and / or the first valve housing 2248, so as to easily connect or separate the first connector 100 and the second connector 200.

[0073] In one embodiment, the second sealing ring 302 is disposed on the first valve plug 2131 .

[0074] like Figure 5As shown in FIG. 1 , a mounting area 203 is provided on the first substrate 102, and the mounting hole 204 is located in the mounting area 203. In addition, a third sealing ring 303 is provided on the first substrate 102 to surround the mounting area 203. After the first connector 100 is installed in the battery pack, the third sealing ring 303 is in sealing contact with the battery pack housing 4 (as shown in FIG. 1 ). Figure 6 As shown), to seal the gap between the first substrate 102 and the battery pack housing 4, which helps prevent contaminants such as water and dust from entering the battery pack.

[0075] Also like Figure 6 As shown in FIG. 1 , a fourth sealing ring 304 is disposed along the circumferential edge of each mounting hole 204 on the first substrate 102. Each fourth sealing ring 304 surrounds the corresponding first valve housing 2248. When the first connector 100 is connected to the second connector 200, the second valve housing 2015 of the second connector 210 abuts against the fourth sealing ring 304 (as shown in FIG. 1 ). Figure 2 In this way, the fourth sealing ring 304 seals the connection position between the first connector 100 and the second connector 200, thereby isolating the internal environment of the connector device 1 from the external environment to prevent pollutants such as water and dust in the external environment from entering the connector device 1.

[0076] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
