The technical scheme of the utility model is further described below by the specific embodiments with reference to the accompanying drawings.
Example 1
The embodiment of the utility model provides a battery box, which can facilitate the assembly of the battery box and is beneficial to reducing the overall deformation degree of the battery box.
Referring to fig. 1 to 10, the battery box includes a bottom plate 1 and a surrounding frame 2, the bottom plate 1 is used for supporting the battery cell, and the surrounding frame 2 is used for defining the position of the battery cell and protecting the battery cell.
In this embodiment, the periphery of the outer edge of the bottom plate 1 is provided with the first plugging portion 101, the enclosure frame 2 is formed by combining a plurality of coamings 21, in this embodiment, the enclosure frame 2 is shaped like a "mouth", and the number of coamings 21 may be a positive integer greater than three. As shown in fig. 9, each of the coamings 21 is provided with a second plug-in portion 201 for plug-in connection with the first plug-in portion 101, the first plug-in portion 101 and the second plug-in portion 201 are plug-in connected so that the base plate 1 and all the coamings 21 are combined to form a sealed case, and a gap between the first plug-in portion 101 and the second plug-in portion 201 is filled with a sealant.
In this embodiment, no welding connection is required between the coaming 21 and the bottom plate 1, so that the coaming 21 and the bottom plate 1 cannot deform due to heat generated by welding in the assembly process, so that the deformation degree of the finally assembled battery box is small, and the dimensional accuracy of the battery box can be effectively ensured.
It should be further noted that the first plug portion 101 and the second plug portion 201 can be plug-connected, and the gap between the first plug portion 101 and the second plug portion 201 is further sealed by the sealant, so that the difficulty of assembling can be effectively reduced, and the battery box can be assembled more simply and conveniently. It should be noted that the heat transfer effect of the sealant is poor, and the heat on the bottom plate 1 is not transferred to the surrounding frame 2 in a large amount.
Optionally, the bottom plate 1 comprises a water cooling plate 11 and connecting strips 12 arranged at two ends of the water cooling plate 11, a plurality of water cooling flow channels 111 are arranged in the water cooling plate 11, two adjacent water cooling flow channels 111 are mutually communicated, and the connecting strips 12 at two ends seal two ends of the water cooling flow channels 111. Specifically, at this time, the water cooling plate 11 may be an extruded profile, and the connecting strips 12 close two ends of the water cooling channels 111, so that all the water cooling channels are mutually communicated, and the cooling liquid can fill all the water cooling channels 111 to cool the battery cells. It should be further noted that each water cooling channel 111 may be in a serial structure or a parallel structure. Preferably, each water cooling channel 111 forms a serpentine cooling channel. It should be further noted that, the heat conducting property of the sealant is worse than that of metal, so that heat on the water-cooling plate 11 is not easy to transfer to the coaming 21, the heat conducting coefficient of the water-cooling plate 11 and the coaming 2 is reduced, and heat loss of the water-cooling plate 11 is reduced.
Optionally, a water inlet joint 13 and a water outlet joint 14 are further installed on the bottom plate 1, and the water inlet joint 13 and the water outlet joint 14 are respectively communicated with the water cooling flow channel 111. Preferably, when the plurality of water cooling channels 111 form a serpentine cooling channel, the water inlet joint 13 and the water outlet joint 14 are respectively communicated with two opposite ends of the serpentine cooling channel. Or the distance between the water cooling flow passage 111 communicated with the water inlet joint 13 and the water cooling flow passage 111 communicated with the water outlet joint 14 is as far as possible so as to improve the cooling effect of the water cooling plate 11.
Alternatively, the water cooling plate 11 is welded to the connecting strip 12, in this embodiment, the connecting strip 12 seals two ends of the water cooling channel 111 and the connecting strip 12 by friction welding to achieve sealing connection, and it should be further noted that the connecting strip 12 may be an aluminum piece, a copper piece or other metal piece formed by machining.
Alternatively, the first insertion portion 101 forms an insertion groove 1001, the shroud 21 is formed with an insertion projection 2001 for insertion connection with the insertion groove 1001, and the insertion projection 2001 is perpendicular to the shroud 21. As shown in fig. 1 and 9, the insertion projection 2001 is inserted into the insertion groove 1001, and the sealant is filled in the gap between the insertion projection 2001 and the insertion groove 1001, thereby improving the connection fastening effect and further improving the sealing performance of the connection.
In one particular embodiment, the opposing sides of the mating protrusion 2001 are provided with a sealant. Specifically, the plugging projection 2001 includes opposite first and second side surfaces, the first side surface being opposite to the first groove wall surface of the plugging groove 1001, the second side surface being opposite to the second groove wall surface of the plugging groove 1001, a sealant being provided on the first side surface to seal a gap between the first side surface and the first groove wall surface, and a sealant being provided on the second side surface to seal a gap between the second side surface and the second groove wall surface. On the one hand, the sealing performance of the battery box is improved by the sealant, on the other hand, the possibility of contact between the coaming 21 and the bottom plate 1 can be effectively reduced by the sealant on both sides, the heat conductivity coefficient of the water cooling plate 11 and the coaming 2 is reduced, and the heat loss of the water cooling plate 11 is reduced.

It should be noted that, the connection between the adjacent two coamings 21 is realized by the L-shaped connection block 4, so that the connection between the coamings 21 can be more stable. It should be further specifically noted that, the existence of the avoiding corner 401 can avoid interference between the L-shaped connecting block 4 and the coaming 21, so as to further facilitate the installation of the battery box. It should be noted that, the screw of the threaded fastener 5 enters the through connection hole 211 and is screwed into the threaded hole, so as to realize the fixed connection between the coaming 21 and the L-shaped connection block 4, and the L-shaped connection block 4 connects the two coamings 21 respectively, that is, realizes the fixed connection of the two coamings 21.
