In this embodiment, the abovementioned cold plate is taken as an example of the temperature regulating plate for description.
For each part of the battery container according to the embodiment of the disclosure, detailed description will be provided as follows.
In an embodiment of the disclosure, the base plate 140 may be a flat plate structure or a similar structure. For example, the base plate 140 may be, but not limited to, a stainless steel plate or an aluminum alloy plate. An accommodating area is disposed on the base plate 140. The accommodating area is configured to place a battery or a battery set. An orthographic projection of the batteries or the battery set on the base plate 140 is located in the accommodating area. The batteries or the battery set may be directly placed in the containing area. Alternatively, other devices, such as cooling devices, may be disposed between the batteries or the battery set and the base plate 140, which is not specifically limited by the embodiment of the disclosure.

The battery container may include one first beam 120 and one second beam 130. The first beam 120 is parallel to the first frame beam, and the second beam 130 is parallel to the second frame beam. The first beam 120 and the second beam 130 separate the accommodating space into four battery compartments 110. The battery set is disposed in each of the four battery compartments 110. Naturally, in actual application, it is also possible that the first beam 120 includes a plurality of first beams and the second beam 130 includes a plurality of second beams. For example, only one first beam 120 is present in the battery container. At this time, the battery container has two battery compartments 110. Alternatively, the battery container has two first beams 120 and one second beam 130. At this time, the battery container has six battery compartments 110. Nonetheless, the embodiment of the disclosure is not limited thereto.

A bottom surface of the interior beam is in contact with a top surface of the base plate 140. The bottom surface of the interior beam is a flat surface, and the top surface of the base plate 140 is a flat surface. As a result, fillet welding may be performed on two sides of the interior beam to connect the interior beam to the base plate 140. A bottom surface of the frame beam is in contact with the top surface of the base plate 140. The bottom surface of the frame beam is a flat surface, and the top surface of the base plate 140 is a flat surface. As a result, fillet welding may be performed on inner and outer sides of the frame beam to connect the frame beam to the base plate 140.

Alternatively, the third adhesive receiving groove 151 may be not in communication with the first adhesive receiving groove 121 and the second adhesive receiving groove 131.
When the third adhesive receiving groove 151 is not in communication with the first adhesive receiving groove 121 and the second adhesive receiving groove 131, as shown in
One or more adhesive receiving grooves may be disposed on the inner side of the battery compartment 110. The adhesive receiving groove may be formed by the first adhesive receiving groove 121, the second adhesive receiving groove 131, and the third adhesive receiving groove 151. When multiple adhesive receiving grooves are disposed on the inner surface of the battery compartment 110, the adhesive receiving grooves may be disposed in parallel.

At this time, a connecting passage may be disposed between adjacent ones of the adhesive receiving grooves to connect the adhesive receiving grooves.
In an embodiment of the disclosure, the battery container may also include the spacer 160. The spacer 160 is disposed in the battery compartment 110. The adhesive receiving portion 161 is disposed on the spacer 160. The adhesive receiving portion 161 is filled with the connection adhesive to connect two sides of the spacer 160 with the batteries.
A third adhesive injection passage is disposed on the spacer 160. The third adhesive injection passage is in communication with the adhesive receiving portion 161. One end of the third adhesive injection passage away from the adhesive 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 the base plate 140.
The spacer 160 may be connected to the first beam 120 and the frame 150. At this time, the active force from the spacer 160 acts on the first beam 120 and the frame 150. That is, after the batteries are adhered to the spacer 160, at least part of the gravity of the batteries and the impact force generated by movement are transmitted through the spacer 160 to the first beam 120 and the frame 150. Accordingly, the gravity of the batteries and the impact force generated by movement acting on the temperature regulating plate may be reduced, and damage to the temperature regulating plate may be prevented.
For example, the spacer 160 and the first beam 120 and the frame 150 may be connected by one of or a combination of welding, bolting, riveting, plug connection, and adhesive connection. For example, the spacer 160 may be connected to the first beam 120 and the frame 150 by welding and adhesive connection, by plug connection and riveting, or the like, which is not specifically limited by the embodiment of the disclosure.

The top surface of the first spacing plate 162 is a surface of the first spacing plate 162 away from the base plate 140. Naturally, in actual application, the one end of the third adhesive injection passage 164 away from the adhesive receiving portion 161 may also be exposed from another surface of the first spacing plate 162, and the embodiment of the disclosure is not limited thereto.
The first spacing plate 162 may be connected to the frame 150 and the first beam 120. At this time, the active force from the first spacing plate 162 acts on the frame 150 and the first beam 120. That is, after the batteries are adhered to the first spacing plate 162, at least part of the gravity of the batteries and the impact force generated by movement are transmitted through the first spacing plate 162 to the frame 150 and the first beam 120.

The connection adhesive in the adhesive receiving groove may flow into the adhesive receiving portion 161 and form a connection adhesive layer in the adhesive receiving portion 161 to connect the batteries with the spacer 160. The connection adhesive layer may be formed in the adhesive receiving portion 161. Alternatively, the connection adhesive may flow over the adhesive receiving portion 161 and form the connection adhesive layer in a gap between the spacer 160 and the batteries.
For example, the spacer 160 may include the first spacing plate 162 or the second spacing plate 163. When the spacer 160 includes the first spacing plate 162, N batteries are in the battery set, and the battery container may include N−1 first spacing plates 162. The N−1 first spacing plates 162 are sequentially arranged in accordance with the arrangement direction of the batteries. The N−1 first spacing plates 162 and the bilateral container beams form N accommodating parts. One battery is disposed in each accommodating part. The adhesive receiving portion 161 is disposed on the first spacing plate 162. The connection adhesive in the adhesive receiving portion 161 is connected with the battery adjacent thereto.
When the spacer 160 includes the second spacing plate 163, N batteries are in the battery set, and the battery container may include N−1 second spacing plates 163. The N−1 second spacing plates 163 are sequentially arranged in accordance with the arrangement direction of the batteries. The N−1 second spacing plates 163 and the bilateral container beams form N accommodating parts. One battery is disposed in each accommodating part. The adhesive receiving portion 161 is disposed on the second spacing plate 163. The connection adhesive in the adhesive receiving portion 161 is connected with the battery adjacent thereto.
Note that, in the embodiment of the disclosure, the structure of the battery container has been described in detail in the implementation of the battery container, and the description thereof will not be repeated herein in the embodiment of the disclosure.
Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the disclosure disclosed herein. The disclosure is intended to cover any variations, uses or adaptations of the disclosure.
