One end of the fourth adhesive injection passage 152is connected to the third adhesive receiving groove 151, and the other end of thefourth adhesive injection passage 152 is disposed on a top surface of the frame150.
[0046] One or more adhesive receiving grooves may be disposed on the innerside of the battery compartment 110. The adhesive receiving groove may beformed by the first adhesive receiving groove 121, the second adhesive receivinggroove 131, and the third adhesive receiving groove 151. When multiple adhesivereceiving grooves are disposed on the inner surface of the battery compartment110, the adhesive receiving grooves may be disposed in parallel. That is, theadhesive receiving grooves are not intersected with each other. At this time, aconnecting passage may be disposed between adjacent ones of the adhesivereceiving grooves to connect the adhesive receiving grooves.
[0047] In an embodiment of the disclosure, the battery container may alsoinclude the spacer 160. The spacer 160 is disposed in the battery compartment110. The adhesive receiving portion 161 is disposed on the spacer 160. Theadhesive receiving portion 161 is filled with the connection adhesive to connecttwo sides of the spacer 160 with the batteries.
[0048] A third adhesive injection passage is disposed on the spacer 160. Thethird adhesive injection passage is in communication with the adhesive receivingportion 161. One end of the third adhesive injection passage away from theadhesive receiving portion 161 is exposed from a top surface of the spacer 160.The top surface of the spacer 160 is a surface of the spacer 160 away from thebase plate 140.
[0049] The spacer 160 may be connected to the first beam 120 and the frame150. At this time, the active force from the spacer 160 acts on the first beam 120and the frame 150. That is, after the batteries are adhered to the spacer 160, atleast part of the gravity of the batteries and the impact force generated bymovement are transmitted through the spacer 160 to the first beam 120 and theframe 150. Accordingly, the gravity of the batteries and the impact forcegenerated by movement acting on the temperature regulating plate may bereduced, and damage to the temperature regulating plate may be prevented.
[0050] For example, the spacer 160 and the first beam 120 and the frame 150may be connected by one of or a combination of welding, bolting, riveting, plugconnection, and adhesive connection. For example, the spacer 160 may beconnected to the first beam 120 and the frame 150 by welding and adhesiveconnection, by plug connection and riveting, or the like, which is not specificallylimited by the embodiment of the disclosure.
[0051] In a feasible embodiment of the disclosure, as shown in FIG. 7, thespacer 160 includes a first spacing plate 162. The first spacing plate 162 isdisposed in the battery compartment 110. A through groove is disposed on thefirst spacing plate 162 to form the adhesive receiving portion 161. The throughgroove penetrates the first spacing plate 162 along the first direction. That is, theadhesive receiving portion 161 on the first spacing plate 162 penetrates the firstspacing plate 162. A connection adhesive in the adhesive receiving portion 161may connect the batteries on the two sides of the first spacing plate 162.
[0052] The through groove extends from one end of the first spacing plate 162to the other end of the first spacing plate 162. That is, the through grooveseparates the first spacing plate 162 into an upper spacing plate and a lowerspacing plate. The adhesive receiving portion 161 is disposed between the upperspacing plate and the lower spacing plate. The connection adhesive in theadhesive receiving portion 161 may connect the batteries on the two sides of thefirst spacing plate 162.
[0053] For example, as shown in FIG. 6, the first direction (the arrangementdirection of the batteries) is a Y direction, and the length direction of the batteriesis an X direction. In the X direction, a through groove G extends from one end ofthe first spacing plate 162 to the other end of the first spacing plate 162 to formthe adhesive receiving portion. In the X direction, a first end of the throughgroove G corresponds to the first adhesive receiving groove 121 on the first beam120, and the first adhesive receiving groove 121 is in communication with thethrough groove G, a second end of the through groove G corresponds to the thirdadhesive receiving groove 151 on the frame 150, and the third adhesive receivinggroove 151 is in communication with the through groove G. The adhesive liquidmay flow into the through groove G along the first adhesive receiving groove 121and / or the third adhesive receiving groove 151, and may as well flow into the firstadhesive receiving groove 121 and / or the third adhesive receiving groove 151along the through groove G, for example, to facilitate adhesive injection. Asanother example, the battery compartment 110 includes two first beams 120disposed opposite to each other. Two ends of the through groove G arerespectively opposite to the two first adhesive receiving grooves 121 of the twofirst beams 120. Optionally, the first adhesive receiving groove 121 is incommunication with the through groove G. The adhesive liquid may flow into thethrough groove G along the first adhesive receiving grooves 121, and may as wellflow into the first adhesive receiving grooves 121 along the through groove G, forexample, to facilitate adhesive injection.
[0054] Naturally, in actual application, the through groove may also be locatedinside the first spacing plate 162. At this time, a communication passage isdisposed between the first adhesive receiving groove 121 on the first beam 120,the third adhesive receiving groove 151 on the frame 150, or the second adhesivereceiving groove 131 on the second beam 130 and the through groove. Theconnection adhesive in the first adhesive receiving groove 121 on the first beam120 or the second adhesive receiving groove 131 on the second beam 130 mayflow into the through groove along the communication passage.
[0055] A third adhesive injection passage 164 is disposed on the first spacingplate 162. The third adhesive injection passage 164 is in communication with theadhesive receiving portion 161. One end of the third adhesive injection passage164 away from the adhesive receiving portion 161 is exposed from a top surfaceof the first spacing plate 162. The top surface of the first spacing plate 162 is asurface of the first spacing plate 162 away from the base plate 140. Naturally, inactual application, the one end of the third adhesive injection passage 164 awayfrom the adhesive receiving portion 161 may also be exposed from anothersurface of the first spacing plate 162, and the embodiment of the disclosure is notlimited thereto.
[0056] The first spacing plate 162 may be connected to the frame 150 and thefirst beam 120. At this time, the active force from the first spacing plate 162 actson the frame 150 and the first beam 120. That is, after the batteries are adhered tothe first spacing plate 162, at least part of the gravity of the batteries and theimpact force generated by movement are transmitted through the first spacingplate 162 to the frame 150 and the first beam 120. Accordingly, the gravity of thebatteries and the impact force generated by movement may be prevented fromentirely acting on the temperature regulating plate, and damage to the temperatureregulating plate may be prevented.
[0057] For example, the first spacing plate 162 may be connected to the frame150 and the first beam 120 by one of or a combination of welding, bolting,riveting, plug connection, and adhesive connection. For example, the first spacingplate 162 may be connected to the frame 150 and the first beam 120 by weldingand adhesive connection, by plug connection and riveting, or the like, which is notspecifically limited by the embodiment of the disclosure.
