[0069] 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.

[0070] Figure 1 The 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 being connected together or separated from 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, 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 the present application, the connector device 1 of the present application is described by taking the first connector 100 as installed on the vehicle body and the second connector 200 as installed on the battery pack as an example.

[0071] like Figure 2 and Figure 5 As shown, the first connector 100 includes a first substrate 101, a shielding plate 150 and a first connector assembly 110. The first substrate 101 has a first mounting surface 105 and a second mounting surface 106 opposite to the first mounting surface 105. Two first mounting holes 104 are also provided on the first substrate 101, and each first mounting hole 104 extends from the first mounting surface 105 to the second mounting surface 106. Figure 6 As shown, the shielding plate 150 is disposed on the first mounting surface 105, and two through holes 1501 are configured on the shielding plate 150. The two first through holes 1501 correspond to the corresponding first mounting holes 104, respectively. The number of the first joint assemblies 110 is also two, and they are respectively installed at the corresponding first mounting holes 104 and the through holes 1501. The two first joint assemblies 110 are respectively used to form a liquid coolant return channel and a liquid coolant outflow channel to facilitate the user to use the first connector 100. Also as shown Figure 2 As shown, in the present application, the first substrate 101 is substantially parallel to the XY plane in the XYZ three-dimensional rectangular coordinate system; the central axis of the first mounting hole 104 is substantially parallel to the Z direction in the XYZ three-dimensional rectangular coordinate system.

[0072] like Fig.12 As shown, the second connector 200 includes two second connector components 220. The two second connector components 220 are adapted to be connected to the corresponding first connector components 110, respectively, so as to connect the second connector 200 to the first connector 100. Of course, the second connector component 220 can also be separated from the first connector component 110 to separate the second connector 200 from the first connector 100.

[0073] Optionally, Fig.12 As shown, the second connector 200 further includes a second substrate 202. The second substrate 202 has a first end surface 205 and a second end surface 206 opposite to the first end surface 205. Two second mounting holes 204 are configured on the second substrate 202, and each mounting hole 204 extends from the first end surface 205 to the second end surface 206. Two second connector assemblies 220 are respectively installed in the corresponding second mounting holes 204. Fig.12 As shown, in the present application, the second substrate 202 is substantially parallel to the XY plane in the XYZ three-dimensional rectangular coordinate system; the central axis of the second mounting hole 204 is substantially parallel to the Z direction in the XYZ three-dimensional rectangular coordinate system.

[0074] Next, the first joint assembly 110 will be described.

[0075] like Figure 3 As shown, the first joint assembly 110 includes a first valve assembly 112 and a first pipe 111 .

[0076] Reference Figure 7 and Figure 8 The first connecting pipe 111 is provided with a first flange 1113 extending radially outward. The first connecting pipe 111 is arranged corresponding to the corresponding through hole 1501 and the first flange 1113 abuts against the shielding plate 150. In this way, the shielding plate 150 supports the first connecting pipe 111.

[0077] Reference Fig. 9 and Fig.10 , the first valve assembly 112 includes a first valve housing 1125. The first valve housing 1125 includes a first pipe section 1121, a second pipe section 1122, and a first shoulder 1123 between the first pipe section 1121 and the second pipe section 1122. The first shoulder 1123 abuts against the second mounting surface 106 of the first substrate 101; and the first pipe section 1121 extends through the corresponding first mounting hole 104 and the corresponding through hole 1501 and is connected to the corresponding first connecting pipe 111.

[0078] In the first connector 100, the first pipe section 1121 is connected to the first connecting pipe 111; at the same time, the first shoulder 1123 of the first valve assembly 112 (or the first valve housing 1125) abuts against the second mounting surface 106 of the first substrate 101, and the first flange 1113 of the first connecting pipe 111 abuts against the shielding plate 150, so that the first connecting pipe 111, the first valve assembly 112, the shielding plate 150 and the first substrate 101 are connected to each other along the Z direction through the structures of the four (for example, the first mounting hole 104, the first flange 1113 and the first shoulder 1123, etc.), without the need for additional connectors. This helps to reduce the number of parts of the first connector 100, reduces the cost of the first connector 100 (and the connector device 1), and also facilitates the assembly of the first connector 100.

[0079] Alternatively, if Figure 7 and Figure 8 As shown, the first connecting pipe 111 is configured with a first receiving groove 1111. At least a portion of the first pipe section 1121 of the first valve housing 1125 is inserted into the first receiving groove 1111. In this way, at least a portion of the first pipe section 1121 is sheathed together with the first connecting pipe 111, which helps to improve the connection stability between the two.

[0080] Also like Figure 7 and Figure 8 As shown, the first receiving groove 1111 includes a first circumferential side wall 1114, and the first flange 1113 is located at the end of the first circumferential side wall 1114 facing the shielding plate 150. The first connecting pipe 111 also includes a first opening 1115 constructed on the first circumferential side wall 1114 and a first elastic sheet 1112 located in the first opening 1115. The first elastic sheet 1112 extends from the edge portion of the first opening 1115 close to the first flange 1113 into the first opening 1115 and is separated from the remaining edge portion of the first opening 1115. Fig. 9 As shown, a first protrusion 1124 protruding radially outward is configured on the first pipe section 1121. The first protrusion 1124 fits into the first opening 1115 and engages with the first elastic sheet 1112. According to this structure, the first elastic sheet 1112 stably holds the first protrusion 1124 in the first opening 1115, so that the first connecting pipe 111 and the first valve assembly 112 are stably connected together without the need for additional connectors. In other embodiments, the first connecting pipe 111 and the first pipe section 1121 (or the first valve housing 1125) can also be threadedly connected.

[0081] Optionally, Fig. 9As shown, a chamfer 1128 is configured on each first shoulder 1123, and the two first joint assemblies 110 are arranged so that the chamfers 1128 of the two first shoulders 1123 face each other. According to this structure, the distance between the two first valve assemblies 112 (or the two first valve housings 1125) can be reduced, thereby making the structure of the first connector 100 more compact. As a result, it is helpful to miniaturize the first connector 100 and the connector device 1 to facilitate installation in a small space.

[0082] Alternatively, if Figure 3 and Figure 4 As shown, the first pipe section 1121 is suitable for being offset in the radial direction of the first mounting hole 104 in the first mounting hole 104, and a floating member 140 is provided between the first pipe section 1121 and the inner surface of the corresponding first mounting hole 104. In this way, in the process of connecting the first connector 100 with the second connector 200, if the second pipe section 1122 of the first valve housing 1125 is not aligned with the second joint assembly 220, the first pipe section 1121 of the first valve housing 1125 is offset in the radial direction of the first mounting hole 104 in the first mounting hole 104 and presses the floating member 140, so that the second pipe section 1122 is also offset accordingly, and then the second pipe section 1122 is aligned with the second joint assembly 220. In this way, the second joint assembly 220 can be smoothly inserted into the second pipe section 1122, so that the first connector 100 and the second connector 200 are connected together.

[0083] Optionally, Figure 3 As shown, a floating member 140 is disposed between each first pipe section 1121 and the inner surface of the corresponding first mounting hole 104, and the two floating members 140 are independent of each other. In this way, when the connector device 1 is used, the two floating members 140 act independently and will not be involved with each other. In addition, since the two floating members 140 are independent of each other, it is also convenient to maintain and replace each floating member 140 separately. In another embodiment, the two floating members 140 can also be connected into a whole.

[0084] Alternatively, if Fig.11 As shown, the floating member 140 is configured as an elastic bushing and is sleeved on the first pipe section 1121. In one embodiment, a plurality of pores 1402 are configured in the bushing, so that the bushing can be compressed. In other embodiments, the floating member 140 can also be a spring, which is well known to those skilled in the art and will not be described in detail here.

[0085] Optionally, Fig.11As shown, an axial cutout 1401 is configured on the bushing. Thus, when the bushing is fitted onto the first pipe segment 1121, the bushing can be opened along the cutout 1401 to install the bushing onto the first pipe segment 1121. After the bushing is fitted into place onto the first pipe segment 1121, the bushing will automatically resume closing to stably fit onto the first pipe segment 1121.

[0086] Next, the second joint assembly 220 will be described.

[0087] like Fig.13 As shown, the second joint assembly 220 includes a second connecting pipe 223 and a second valve assembly 224. The second valve assembly 224 includes a second valve housing 2248. The second connecting pipe 223 is configured with a second flange 2233 extending radially outward. The second valve housing 2248 includes a first connecting section 2241, a second connecting section 2242, and a mating section 2249 between the first connecting section 2241 and the second connecting section 2242. The first connecting section 2241 is configured with a second shoulder 2243 extending radially outward.

[0088] Also like Fig.13 As shown, when the second joint assembly 220 is mounted on the second substrate 202, the second connecting section 2242 extends through the second mounting hole 204 and is connected to the second connecting pipe 223. The second flange 2233 abuts on the first end face 205. At the same time, the second shoulder 2243 abuts on the second end face 206. In the second connector 200, the second connecting pipe 223, the second valve housing 2248 and the second substrate 202 are mutually constrained and assembled together along the Z direction through their own structures (for example, through the second mounting hole 204, the second flange 2233 and the second shoulder 2243), without the need for additional connectors. As a result, the number of parts of the second connector 200 is reduced, which reduces the cost of the second connector 200 (and the connector device 1), and also facilitates the assembly of the second connector 200.

[0089] like Fig.15 As shown, the second connecting pipe 223 is configured with a second connecting groove 2231. At least a portion of the second connecting section 2242 is inserted into the second connecting groove 2231. In this way, at least a portion of the second connecting section 2242 is sheathed together with the second connecting pipe 223, which helps to improve the connection stability between the two.

[0090] Also like Fig.15As shown, the second connection groove 2231 includes a second circumferential side wall 2234, and the second flange 2233 is located at the end of the second circumferential side wall 2234 facing the second substrate 202. The second connecting pipe 223 includes a second opening 2235 configured on the second circumferential side wall 2234 and a second elastic sheet 2232 located in the second opening 2235. The second elastic sheet 2232 extends from the edge portion of the second opening 2235 close to the second flange 2233 into the second opening 2235 and is separated from the remaining edge portion of the second opening 2235. Fig.14 As shown, a second protrusion 2244 protruding radially outward is configured on the second connecting section 2242. The second protrusion 2244 is adapted to fit into the second opening 2235 and engage with the second elastic sheet 2232. According to this structure, the second elastic sheet 2232 stably holds the second protrusion 2244 in the second opening 2235, so that the second connecting pipe 223 and the second valve housing 2248 are stably connected together without the need for additional fixings. In other embodiments, the second connecting pipe 223 and the second connecting section 2242 may also be threadedly connected.

[0091] The working process of the connector device 1 is described below.

[0092] like Figure 3 As shown, the first valve assembly 112 also includes a first valve core assembly 113 slidably disposed in the first valve housing 1125. The first valve core assembly 113 includes: a tubular sliding sleeve 1131, a first valve plug 1132 disposed in the sliding sleeve 1131, and a first elastic member 1133. The first valve plug 1132 is suitable for sealing contact with or separation from the inner surface of the sliding sleeve 1131. The two ends of the first elastic member 1133 respectively abut the sliding sleeve 1131 and the first valve plug 1132, so that the sliding sleeve 1131 can axially reciprocate relative to the first valve core assembly 113.

[0093] like Fig.13 As shown, the second valve assembly 224 also includes a second valve core assembly 213. The second valve core assembly 213 includes a second valve plug 2131 and a second elastic member 2133. The second valve plug 2131 is adapted to be in sealing contact with or separated from the inner surface of the first connecting section 2241. Both ends of the second elastic member 2133 abut against the second valve plug 2131 and the second connecting pipe 223, respectively, so that the second valve housing 2248 and the second valve plug 2131 can axially reciprocate relative to each other.

[0094] like Fig.16As shown, when the first connector 100 is connected to the second connector 200, the first connecting section 2241 of the second valve housing 2248 of the second connector 200 is inserted into the second pipe section 1122 of the first valve housing 1125 of the first connector 100. The first valve plug 1132 abuts against the second valve plug 2131, and the first connecting section 2241 of the second valve housing 2248 abuts against the sliding sleeve 1131. The second 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 pointing to the first connector 100 along the Z direction) and pushes the sliding sleeve 1131 to move. As a result, the second valve plug 2131 is separated from the inner surface of the first connecting section 2241, and the second connector 200 is turned on (at this time, the second elastic member 2133 is compressed); the first valve plug 1132 is also separated from the inner surface of the sliding sleeve 1131, and the first connector 100 is turned on (at this time, the first elastic member 1133 is compressed). In this way, the connector assembly 1 is conductive and forms a closed liquid coolant circulation loop, and the liquid coolant can flow through the connector assembly 1.

[0095] When the first connector 100 is separated from the second connector 200, the first connecting section 2241 of the second valve housing 2248 of the second connector 200 is pulled out from the second pipe section 1122 of the first valve housing 1125 of the first connector 100. The second elastic member 2133 restores and drives the second valve housing 2248 to return to the inner surface of the first connecting section 2241 of the second valve housing 2248 to seal contact with the second valve plug 2131, and the second connector 200 is cut off. The first elastic member 1133 restores and drives the sleeve 1131 to return to seal contact with the first valve plug 1132, and the first connector 100 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.

[0096] 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.
