[0044] Through the above-mentioned drawings, specific embodiments of the present application have been shown, and there will be more detailed descriptions hereinafter. These drawings and textual descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed implementation manners

[0045] As described in the background art, the tray is an important part of the battery pack, which can accommodate the battery cell module and control components of the battery pack, etc., so as to play a supporting and protecting role for the battery cell module and control components. Electric vehicles usually have one or more flow channels to realize the transportation of the cooling medium through the flow channels. In the related art, the flow channels can usually be relatively fixed to the tray to install the flow channels through the tray.

[0046] In the tray of the related art, the flow channels can be installed on the outside of the tray. And, in order to ensure the stability of the installation of the flow channels, a fixing structure for fixing the flow channels is usually required to be provided on the tray. For example, the flow channels can be fixedly connected to the frame of the tray through fixing structures such as fixing ties or fixing bolts, so that the flow channels are fixed to the tray through the fixing structures.

[0047] However, since a fixing structure is required to install the flow channels on the outside of the tray, the tray cannot directly fix the flow channels, and the function of the tray is relatively single. Moreover, the flow channels need to occupy the space outside the tray, so that the assembly space of the tray is compressed. In addition, the tray and the flow channels need to be connected through fixing structures such as fixing ties or fixing bolts, and the integration of the tray is poor.

[0048] To solve the above technical problems, the embodiments of the present application provide a tray, a battery pack and an electrical equipment. The tray includes a frame and flow channels. An accommodation cavity is provided inside the frame, and an opening communicating with the accommodation cavity; the flow channels are arranged in the accommodation cavity, and the flow channels communicate with the outside of the frame through the opening. By arranging the flow channels in the accommodation cavity inside the frame, the frame can play a certain protective role for the flow channels, reducing the possibility of damage to the flow channels and other situations.

[0049] In the tray of the related art, the flow channels usually need to be installed on the outside of the tray, so that the flow channels need to occupy the space outside the tray. And, in order to ensure the stability of the installation of the flow channels, a fixing structure is usually required to be provided on the tray to fix the flow channels to the tray through the fixing structure, which further compresses the assembly space of the tray.

[0050] Compared with the trays in the related art, the tray of the embodiment of the present application can be provided with a receiving cavity, so that the flow channel can be arranged in the receiving cavity, enabling the tray to not only support and protect the battery cell module and the control device, but also integrate the flow channel inside the tray, making the functions of the tray more abundant and improving the integration of the tray.

[0051] Here, the exemplary embodiments will be described in detail, and the examples are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0052] The technical solution of the present application and how the technical solution of the present application solves the above technical problems will be described in detail below with specific embodiments. These several specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below with reference to the accompanying drawings.

[0053] Referring to Figure 1 and Figure 2 , an embodiment of the present application provides a tray, including a frame 100 and a flow channel 200. A receiving cavity 130 is provided inside the frame 100, and an opening communicating with the receiving cavity 130. The flow channel 200 is arranged in the receiving cavity 130, and the flow channel 200 communicates with the outside of the frame 100 through the opening, so that the flow channel 200 is arranged in the receiving cavity 130 inside the frame 100, thereby enabling the frame 100 to play a certain protective role on the flow channel 200 and reducing the possibility of damage to the flow channel 200.

[0054] In some possible implementation manners, the frame 100 may include a front beam 100a and a rear beam 100b that are parallel and opposite to each other, and two side beams 100c that are parallel and opposite to each other. The front beam 100a, the rear beam 100b, and the two side beams 100c together enclose a rectangular frame 100, and the inside of the frame 100 can be used to accommodate the battery cell module to play a certain supporting and protecting role on the battery cell module through the frame 100.

[0055] When the installation base is set as the vehicle body and the battery pack is applied to an electric vehicle, the frame 100 of the battery pack is arranged in the horizontal direction. The front beam 100a can face the front side of the vehicle, the rear beam 100b can face the rear side of the vehicle, one of the two side beams 100c can face the left side of the vehicle, and the other of the two side beams 100c can face the right side of the vehicle. The length of the side beam 100c can be greater than the lengths of the front beam 100a and the rear beam 100b.

[0056] Exemplarily, at least one of the two side beams 100c may be provided with a flow channel 200.

[0057] For example, when the flow channel 200 is used to convey a cooling medium from the front side of the vehicle to the rear side of the vehicle, the flow channel 200 may be disposed inside the side beam 100c, and the extending direction of the flow channel 200 is parallel to the direction connecting the front and rear sides of the vehicle, so that the flow channel 200 can be used to realize the conveying process of the cooling medium.

[0058] The length of the side beam 100c is greater than the lengths of the front beam 100a and the rear beam 100b. By disposing the flow channel 200 in the side beam 100c, the length advantage of the side beam 100c can be better utilized, so that the length of the flow channel 200 located inside the frame 100 is greater, and the space outside the tray occupied by the flow channel 200 is further reduced.

[0059] Moreover, the side beam 100c generally does not need to be provided with structures such as connectors and control valves, so that the structure of the side beam 100c is more complete, and the airtightness of the accommodation cavity 130 formed inside the side beam 100c is better. By disposing the flow channel 200 inside the side beam 100c, the side beam 100c can better support and protect the flow channel 200, and further reduce the possibility of damage to the flow channel 200.

[0060] Referring to Figure 1 and Figure 2 , in some possible implementation manners, the frame 100 may include a main body 110 and a connecting portion 120. The main body 110 may be at least used for accommodating the battery cell module. The connecting portion 120 may be disposed outside the main body 110, and the connecting portion 120 may be at least used for connecting to an installation base such as a vehicle body, so that the battery pack can be connected to the installation base through the connecting portion 120.

[0061] Exemplarily, the flow channel 200 may be disposed between the main body 110 and the connecting portion 120. The flow channel 200 may be fixedly connected to the main body 110, and / or the flow channel 200 may be fixedly connected to the connecting portion 120, so as to jointly accommodate the flow channel 200 through the main body 110 and the connecting portion 120. By disposing the accommodation cavity 130 between the main body 110 and the connecting portion 120, the volume of the accommodation cavity 130 can be increased, and the installation space of the flow channel 200 in the accommodation cavity 130 can be increased.

[0062] Moreover, when the volume of the accommodation cavity 130 is increased, the cross-sectional area of the flow channel 200 can also be increased, and the flow rate of the cooling medium in the flow channel 200 can be increased. Compared with the implementation manner in which the flow channel 200 is disposed outside the frame 100, by disposing the flow channel 200 inside the frame 100, increasing the cross-sectional area of the flow channel 200 does not occupy the assembly space of the battery pack, so that the setting manner of the flow channel 200 can be made more reasonable.

[0063] It is easily understandable that by disposing the accommodation cavity 130 between the main body 110 and the connecting portion 120, a part of the accommodation cavity 130 is disposed inside the main body 110, and the remaining part of the accommodation cavity 130 is disposed inside the connecting portion 120. The main body 110 and the connecting portion 120 jointly enclose the accommodation cavity 130, so that the accommodation cavity 130 does not occupy a large amount of the inner space of the main body 110 or the connecting portion 120, and the inner sides of the main body 110 and the connecting portion 120 can be provided with the strengthening structure 140. Thus, through the provided strengthening structure 140, the stability of the main body 110 and the connecting portion 120 can be improved.

[0064] Exemplarily, taking the flow channel 200 disposed on the side beam 100c as an example, in a plane perpendicular to the extending direction of the main body 110, the length direction of the main body 110 can be the thickness direction of the battery pack, and the two sides of the main body 110 along the length direction are respectively the inner side of the frame 100 and the outer side of the frame 100.

[0065] The length direction of the main body 110 and the length direction of the connecting portion 120 can be arranged crosswise. The connecting portion 120 can be disposed at the bottom of the main body 110, and the length direction of the connecting portion 120 can be arranged parallel to the extending direction from the inner side of the frame 100 to the outer side of the frame 100, so as to make the process of installing the connecting portion 120 on an installation base such as a vehicle body more convenient.

[0066] The first end of the connecting portion 120 can be connected to the main body 110, the second end of the connecting portion 120 can extend toward the outer side of the main body 110, and the length direction of the connecting portion 120 can be arranged perpendicular to the length direction of the main body 110. The main body 110 and the connecting portion 120 can form a bending portion 150, and the bending portion 150 can be fixedly connected to the flow channel 200, so that the flow channel 200 can be relatively fixed to the main body 110 and the connecting portion 120 through the bending portion 150.

[0067] Exemplarily, the bending portion 150 can be jointly formed by the main body 110 and the connecting portion 120. The main body 110 forms the first part of the bending portion 150, the connecting portion 120 forms the second part of the bending portion 150, and an included angle is formed between the first part of the bending portion 150 and the second part of the bending portion 150.

[0068] For example, when the length direction of the main body 110 and the length direction of the connecting portion 120 are arranged perpendicular to each other, the first part of the bending portion 150 and the second part of the bending portion 150 can be arranged perpendicular to each other, and the inner surface of the bending portion 150 can be used to form the accommodation cavity 130, and the inner surface of the bending portion 150 can face the flow channel 200.

[0069] Refer to Figure 1 and Figure 2, in some possible embodiments, taking a plane perpendicular to the extending direction of the flow channel 200 as a cross-section, the cross-sectional shape of the flow channel 200 can be set as a circular tube shape. The axial direction of the flow channel 200 is arranged parallel to the extending direction of the frame 100.

[0070] Exemplarily, the flow channel 200 can be fixed to the frame 100 by means such as welding or screw connection. Or, the flow channel 200 can also be integrally formed with the frame 100, so as to make the connection between the flow channel 200 and the frame 100 more stable and reduce the possibility of the flow channel 200 detaching from the frame 100.

[0071] For example, the main body 110, the connecting portion 120 and the flow channel 200 can be integrally formed, so as to make the overall structure of the tray more stable. And there is no need to connect and fix the flow channel 200 to the frame 100, making the assembly process of the frame 100 more convenient, thereby improving the assembly efficiency of the frame 100.

[0072] It is easy to understand that when the battery pack is in a working state, the battery pack frame 100 may generate relatively large shaking. By integrally forming the flow channel 200 with the frame 100, the possibility of the flow channel 200 becoming loose and other situations can be reduced, the stability of the connection between the flow channel 200 and the frame 100 can be improved, and the possibility of the flow channel 200 colliding with the frame 100 to generate noise can be reduced.

[0073] Exemplarily, in a plane perpendicular to the extending direction of the flow channel 200, the flow channel 200 can include a connected first part and a second part. The first part and the second part of the flow channel 200 can be arranged circumferentially around the flow channel 200 to enclose a circular cavity, and the circular cavity can be used to accommodate a cooling medium.

[0074] The first part of the flow channel 200 can be fixedly connected to the bending portion 150, and the second part of the flow channel 200 can be fixedly connected to at least one of the main body 110 and the connecting portion 120, so as to make the connection between the flow channel 200 and the frame 100 more stable and reduce the possibility of mutual impact and other situations between the flow channel 200 and the frame 100.

[0075] The bending portion 150 can be reused to form the first part of the flow channel 200, so as to make the forming process of the frame 100 more convenient. And the bending portion 150 forming the first part of the flow channel 200 can also increase the connection strength between the flow channel 200 and the frame 100 and reduce the possibility of loosening and other situations between the flow channel 200 and the frame 100.

[0076] Exemplarily, the second part of the flow channel 200 may be provided with reinforcing ribs 210. The second part of the flow channel 200 may be fixedly connected to at least one of the main body 110 and the connecting part 120 through the reinforcing ribs 210, so as to make the connection between the flow channel 200 and the frame 100 more stable.

[0077] The number of the reinforcing ribs 210 may be set to one or more.

[0078] The number of the reinforcing ribs 210 may be set to one. The second part of the flow channel 200 may be fixedly connected to the main body 110 through the reinforcing ribs 210. Setting the number of the reinforcing ribs 210 to one can reduce the overall weight of the tray and can also reduce the overall cost of the tray. The reinforcing ribs 210 can also be used to form an energy-absorbing structure. When the frame 100 is subjected to a lateral collision, the reinforcing ribs 210 can absorb part of the collision energy, thereby reducing the possibility of damage to the flow channel 200.

[0079] Alternatively, the number of the reinforcing ribs 210 may also be set to multiple. The multiple reinforcing members may be arranged circumferentially along the flow channel 200. When the number of the reinforcing ribs 210 is set to multiple, the second part of the flow channel 200 may be fixedly connected to the main body 110 through some of the reinforcing ribs 210, and the second part of the flow channel 200 may be fixedly connected to the connecting part 120 through the remaining reinforcing ribs 210.

[0080] When the number of the reinforcing ribs 210 is set to multiple, the flow channel 200 is fixedly connected to the main body 110 and the connecting part 120 through the multiple reinforcing ribs 210, so as to improve the connection strength between the flow channel 200 and the frame 100, reduce the possibility of detachment between the flow channel 200 and the frame 100, and make the installation of the flow channel 200 more stable.

[0081] By adopting the above technical solution, by providing the accommodation cavity 130 inside the frame 100, the flow channel 200 can be arranged in the accommodation cavity 130 located inside the frame 100. The first part of the flow channel 200 can be fixedly connected to the bending part 150 of the frame 100, and the second part of the flow channel 200 can be fixed to the frame 100 through the reinforcing ribs 210, so as to make the connection between the flow channel 200 and the frame 100 more stable.

[0082] Refer to Figures 2 - 5 , in some possible implementation manners, the tray may further include a joint 300. The joint 300 may be fixedly connected to the frame 100. The joint 300 communicates with the flow channel 200 through an opening. The flow channel 200 can communicate with a pipeline located outside the battery pack through the joint 300, so as to realize the transmission process of the cooling medium.

[0083] For example, the joint 300 may be provided with an inserting portion 310 . The inserting portion 310 may be inserted into the flow channel 200 , and the joint 300 may be communicated with the flow channel 200 through the inserting portion 310 .

[0084] The outer surface of the plug-in part 310 may be provided with at least one mounting groove 311. A sealing ring 312 is provided in the mounting groove 311, the inner side of the sealing ring 312 abuts against the groove bottom surface of the mounting groove 311, and the outer side of the sealing ring 312 abuts against the inner surface of the flow channel 200, so that the gap between the outer surface of the plug-in part 310 and the inner surface of the flow channel 200 can be closed by the sealing ring 312, reducing the possibility of the cooling medium flowing out from between the plug-in part 310 and the flow channel 200.

[0085] The number of the mounting grooves 311 can be set to two, and the two mounting grooves 311 are arranged along the extension direction of the plug-in part 310. A sealing ring 312 is arranged in each mounting groove 311, so that the sealing between the plug-in part 310 and the flow channel 200 can be achieved through the two sealing rings 312, thereby improving the sealing effect of the sealing ring 312 on the plug-in part 310 and the flow channel 200.

[0086] For example, the frame 100 may be provided with a fixing platform 160. The joint 300 may be provided with an abutting portion 320 and a locking member 321, and the abutting portion 320 is fixedly connected to the fixing platform 160 through the locking member 321, so that the connection between the joint 300 and the frame 100 is more stable.

[0087] The fixing platform 160 can be fixedly set on at least one of the main body 110 and the connecting part 120, and the abutment portion 320 can be arranged on the outside of the plug-in portion 310. When the plug-in portion 310 is inserted into the flow channel 200, the abutment portion 320 can abut against the fixing platform 160. The abutment portion 320 can be fixed to the fixing platform 160 by the locking member 321, thereby realizing the connection between the joint 300 and the frame 100.

[0088] The fixing platform 160 can be integrally formed with the frame 100 to make the structure of the fixing platform 160 and the frame 100 more stable, thereby reducing the possibility of the fixing platform 160 being detached from the frame 100 .

[0089] The fixing platform 160 can also be relatively fixed to the frame 100 by means of plug-in or bolt connection. The fixing platform 160 and the frame 100 can be processed and formed separately, which makes the processing process of the fixing platform 160 and the frame 100 more convenient and reduces the preparation cost of the fixing platform 160 and the frame 100. The locking member 321 can be set as a locking bolt, and the bolt head of the locking bolt can abut against the surface of the abutment 320 away from the fixing platform 160. The threaded section of the locking bolt can be penetrated into the fixing platform 160, so that the abutment 320 can be connected to the fixing platform 160 through the locking bolt.

[0090] When it is necessary to connect the joint 300 with the flow channel 200 so that the cooling medium in the flow channel 200 can be connected with the pipeline located outside the battery pack through the joint 300, the plug-in part 310 can be inserted into the flow channel 200. The outer side of the sealing ring 312 can be abutted against the inner surface of the flow channel 200. The abutting part 320 moves towards the fixing table 160 and abuts against the fixing table 160. Then, the threaded section of the locking part 321 is threadedly connected with the fixing table 160, so that the joint 300 can be fixed to the frame 100, and the joint 300 is connected with the flow channel 200.

[0091] In summary, the tray includes a frame 100 and a flow channel 200. An accommodation cavity 130 is arranged inside the frame 100, and an opening communicated with the accommodation cavity 130; the flow channel 200 is arranged in the accommodation cavity 130, and the flow channel 200 is communicated with the outside of the frame 100 through the opening. By arranging the flow channel 200 in the accommodation cavity 130 inside the frame 100, the frame 100 can play a certain protective role on the flow channel 200, reducing the possibility of damage to the flow channel 200.

[0092] In the trays of related technologies, the flow channel 200 usually needs to be installed outside the tray, so that the flow channel 200 needs to occupy the space outside the tray. Moreover, in order to ensure the installation stability of the flow channel 200, a fixing structure usually needs to be arranged on the tray so that the flow channel 200 is fixed to the tray through the fixing structure, which further compresses the assembly space of the tray.
