[0055] 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.

[0056] Figure 1 The connector device 1 according to one embodiment of the present application is schematically shown. Figure 1As 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 (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 installed on the vehicle body and the second connector 200 installed on the battery pack as an example.

[0057] 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 mounting holes 104 are provided on the first substrate 101, and each mounting hole 104 extends from the first mounting surface 105 to the second mounting surface 106. The shielding plate 150 is movably provided on the first mounting surface 105, and the shielding plate 150 is configured with two through holes 1501 (such as Figure 6 As shown). The two through holes 1501 correspond to the two mounting holes 104 on the first substrate 101 respectively. The number of the first joint components 110 is also two, and they are respectively installed at the corresponding mounting holes 104 and the through holes 1501 (this will be described below). The two first joint components 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. In the present application, the first substrate 101 is generally parallel to the XY plane in the XYZ three-dimensional rectangular coordinate system; the central axis of the mounting hole 104 is generally parallel to the Z direction in the XYZ three-dimensional rectangular coordinate system.

[0058] like Fig.12 As shown, the second connector 200 includes two second connector assemblies 220. The two second connector assemblies 220 are adapted to be connected to the corresponding first connector assemblies 110, respectively, so as to connect the second connector 200 and the first connector 100 together (which will be described below). Of course, the second connector assembly 220 can also be separated from the first connector assembly 110 to separate the second connector 200 from the first connector 100. Optionally, as Fig.12As shown, the second connector 200 further includes a second substrate 202 , and two second connector assemblies 220 are disposed on the second substrate 202 .

[0059] Next, the first joint assembly 110 will be described.

[0060] like Figure 3 As shown, the first joint assembly 110 includes a pipe 111. Figure 7 and Figure 8 The pipe 111 is provided with a flange 1113 extending radially outward. The pipe 111 is arranged corresponding to the corresponding through hole 1501 and the flange 1113 abuts against the shielding plate 150 (such as Figure 3 In other words, the shielding plate 150 supports the pipe 111.

[0061] Overall, the first substrate 101 holds the support shielding plate 150, and the shielding plate 150 holds the support flange 1113. In this way, the pipe 111 (or the first connector assembly 110) will not fall off from the first substrate 101 or the shielding plate 150, thereby preventing the first connector 100 from being damaged.

[0062] Also like Figure 3 As shown, the first joint assembly 110 also includes a valve assembly 112. Figure 3 and Fig. 9 As shown, the valve assembly 112 includes a valve housing 1125. The valve housing 1125 includes a body 1129 and a first pipe section 1121 extending from the body 1129. The first pipe section 1121 extends through the corresponding mounting hole 104 and the corresponding through hole 1501 and is connected to the connecting pipe 111 (for example, the first pipe section 1121 is inserted into the connecting pipe 111). The shielding plate 150 and the flange 1113 always keep covering the gap between the valve housing 1125 and the corresponding mounting hole 104. In this way, the first joint assembly 110 and / or the shielding plate 150 can be effectively prevented from falling off, and external contaminants can be prevented from entering the mounting hole 104.

[0063] In one embodiment, in the first connector 100, the first joint assembly 110 is adapted to be offset in the XY plane (i.e., offset in the radial direction of the mounting hole 104). It is known that the offset may occur during the installation of the connector device 1 or during the use of the connector device 1. The shielding plate 150 is movably disposed on the first mounting surface 105 so as to be able to move with the offset of the first joint assembly 110. For example, in the process of connecting the first connector 100 to the second connector 200, if the body 1129 of the valve housing 1125 is not aligned with the second joint assembly 220, the valve housing 1125 of the first joint assembly 110 can be substantially offset in the radial direction of the mounting hole 104 until the second joint assembly 220 is aligned with the body 1129. The second joint assembly 220 can also be smoothly inserted into the body 1129, thereby realizing the connection between the first connector 100 and the second connector 200. In other words, the first valve assembly 112 can adapt to the assembly deviation when the first connector 100 and the second connector 200 are docked. It is known that, when the connector device 1 is installed and put into use, the first connector 100 may also be offset in the XY plane due to the influence of the external use environment.

[0064] like Figure 6 As shown, both ends of the circumferential edge 1502 of the shielding plate 150 form arc portions 1503. The arc portions 1503 are concentric with the corresponding through holes 1501. Fig.10 As shown, a protrusion 1127 suitable for contacting the inner surface of the connecting pipe 111 is configured on the outer surface of the first pipe section 1121. The radius A of the arc portion 1503 and the radius E of the through hole 1501 (as shown in FIG. Figure 6 As shown), the radius B of the mounting hole 104 (as shown Figure 5 As shown), the radius D of the flange 1113 (as shown Figure 8 As shown), and the outer radius G of the protrusion 1127 (as Fig.10 The following relationship is satisfied:

[0065] (AB)+(EG)>X; and D+G>2E;

[0066] Wherein, X is the maximum preset offset of the first pipe section 1121 in the corresponding mounting hole 104 along the radial direction of the mounting hole 104 .

[0067] When the dimensions of the various parts of the first connector 100 satisfy the relationship of the above formula, no matter how the first connector assembly 110 is offset in the XY plane, the shielding plate 150 and the flange 1113 can always completely cover the gap between the valve housing 1125 and the corresponding mounting hole 104, thereby ensuring that the first substrate 101 always supports the shielding plate 150, and the shielding plate 150 always supports the flange 1113, thereby more effectively preventing the first connector assembly 110 from falling off from the first substrate 101 or the shielding plate 150. In addition, dust is also prevented from falling into the mounting hole 104. It should be understood that those skilled in the art can set the value of X according to the situation, and the value of X should satisfy the above relationship.

[0068] like Figure 3 As shown, a floating member 140 is provided between the first pipe section 1121 and the corresponding mounting hole 104. Thus, when the first pipe section 1121 deviates radially in the mounting hole 104, the floating member 140 acts as a buffer to prevent the first connector 100 from being damaged.

[0069] Alternatively, if Fig.11 As shown, the floating member 140 is constructed as an elastic bushing and is sleeved on the first pipe section 1121. In one embodiment, a plurality of pores 1402 are constructed in the bushing, which makes the bushing suitable for being compressed. In addition, since the baffle 150 and the flange 1113 always cover the gap between the valve housing 1125 and the corresponding mounting hole 104, the bushing is always covered. This can prevent pollutants in the external environment from contaminating the bushing. 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 repeated here.

[0070] Optionally, Fig.11 As shown, an axial cutout 1401 is configured on the bushing. Thus, when assembling the bushing, the bushing can be opened along the cutout 1401 to install the bushing on the first pipe section 1121. After the bushing is assembled in place on the first pipe section 1121, the bushing will automatically resume closing to stably fit on the first pipe section 1121.

[0071] Optionally, Figure 4 As shown, the floating member 140 has a mating end face 1403 facing the flange 1113, and the mating end face 1403 is flush with the first mounting surface 105. In this way, when the shielding plate 150 moves along the first mounting surface 105, it will not be blocked by the floating member 140, and the offset movement of the first pipe section 1121 will not be hindered by the shielding plate 150. It should be understood that the mating end face 1403 can also be recessed in the mounting hole 104.

[0072] A floating member 140 is provided between each first pipe section 1121 and the corresponding mounting hole 104, and the two floating members 140 are independent of each other. Thus, 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.

[0073] Alternatively, if Fig. 9 and Fig.10 As shown, the body 1129 of the valve housing 1125 includes a second pipe section 1122 and a shoulder 1123, and the shoulder 1123 is located between the first pipe section 1121 and the second pipe section 1122. Figure 3 As shown, the shoulder 1123 abuts the second mounting surface 106 of the first substrate 101. In this way, in the first connector 100, the first pipe section 1121 is inserted into the connecting pipe 111, so that the valve assembly 112 is connected to the connecting pipe 111; at the same time, the shoulder 1123 of the valve assembly 112 (or the valve housing 1125) abuts the second mounting surface 106 of the first substrate 101, and the flange 1113 of the connecting pipe 111 abuts the shielding plate 150, thereby realizing the interconnection of the connecting pipe 111, the valve assembly 112, the shielding plate 150 and the first substrate 101, that is, a stable and reliable connection can be achieved without 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.

[0074] The working process of the first connector 100 is described below.

[0075] like Figure 3 As shown, the valve assembly 112 includes a valve core assembly 113 disposed in a valve housing 1125. The valve core assembly 113 includes: a tubular sliding sleeve 1131, a valve plug 1132 disposed in the sliding sleeve 1131, and an elastic member 1133. The two ends of the elastic member 1133 abut against the sliding sleeve 1131 and the valve plug 1132 respectively. The sliding sleeve 1131 is in sliding and sealing contact with the inner surface of the first pipe section 1121; the valve plug 1132 is suitable for sealing contact or separation with the inner surface of the sliding sleeve 1131.

[0076] When the second joint assembly 220 of the second connector 200 is inserted into the second pipe section 1122, the second joint assembly 220 pushes the sleeve 1131 in the direction from the valve assembly 112 to the pipe 111 (i.e., generally in the direction of the Z direction to the pipe 111), so that the sleeve 1131 moves generally in the direction of the Z direction to the pipe 111 relative to the valve housing 1125 and separates from the valve plug 1132 (at this time, the elastic member 1133 is squeezed). In this way, the valve assembly 112 is turned on and a closed liquid coolant circulation loop is formed. The liquid coolant can flow through the first connector 100 and the second connector 200.

[0077] When the second connector assembly 220 of the second connector 200 is pulled out from the second pipe section 1122, the elastic member 1133 recovers and drives the sleeve 1131 to return to a sealed contact with the sleeve 1131. In this way, the valve assembly 112 is cut off, the liquid coolant circulation loop is disconnected, and the liquid coolant will not leak from the valve assembly 112. 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.

[0078] 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.
