[0035] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0036] The beam structure 100 according to an embodiment of the present utility model will be described below with reference to the drawings.

[0037] As Figure 1 shown, the beam structure 100 according to an embodiment of the present utility model is used for a tray. The beam structure 100 is fixedly connected or integrally connected to the tray body of the tray, so that the beam structure 100 and the tray are an integral whole, and the beam structure 100 includes a beam body 1.

[0038] Specifically, as Figure 1 and Figure 2 It should be noted that there seems to be an incomplete or incorrect description in the original text at the end (lines 47 - 50). The translation is done based on the existing content as accurately as possible. If there are any further clarifications or corrections to the original text, the translation can be adjusted accordingly.As shown, at least one side of both sides in the thickness direction of the beam body 1 is provided with a receiving groove 13, and the receiving groove 13 extends along the length direction of the beam body 1 for placing the electrical connector 200. It can be understood that the receiving groove 13 can be provided only on one side of both sides in the thickness direction of the beam body 1, or can be provided on both sides in the thickness direction of the beam body 1 at the same time, and the receiving groove 13 on the beam body 1 can be arranged according to the wiring position and cross-sectional shape of different electrical connectors 200. The cross-sectional shape of the electrical connector 200 can be circular or rectangular. If the cross-sectional shape of the electrical connector 200 is circular, the dimension in the depth direction of the receiving groove 13 is adapted to the cross-sectional diameter of the electrical connector 200. If the cross-sectional shape of the electrical connector 200 is rectangular, the dimension in the depth direction of the receiving groove 13 is adapted to the cross-sectional length of the electrical connector 200. The adaptability between the receiving groove 13 and the electrical connector 200 can be improved.

[0039] The receiving groove 13 can be provided at any position on both sides in the thickness direction of the beam body 1 and avoid other electrical components in the tray, so that the beam structure 100 in the tray and other electrical components can reasonably allocate the volume space in the tray together, and the volume utilization rate in the tray can be improved. Moreover, by placing the electrical connector 200 in the receiving groove 13, the electrical connector 200 can be prevented from contacting other electrical components, ensuring the safety and reliability of the electrical connector 200 and other electrical components. The electrical connector 200 can connect the battery management system in the battery pack and the vehicle drive unit, and convert the electric energy stored in the battery pack into the power required by the vehicle.

[0040] For example, as Figure 1 and Figure 2 shown, by placing the electrical connector 200 in the receiving groove 13, interference of the electrical connector 200 during the assembly process of the tray and the battery pack of the battery can be avoided. Therefore, the beam structure 100 of the present application is also beneficial to improving the assembly efficiency of the tray and other components and shortening the production beat.

[0041] According to the beam structure 100 of the embodiment of the present utility model, by adding a receiving groove 13 on at least one side of both sides in the thickness direction of the beam body 1 and placing the electrical connector 200 in the receiving groove 13, the volume utilization rate in the tray can be improved, and at the same time, the electrical connector 200 can be prevented from contacting other electrical components, ensuring the safety and reliability of the electrical connector 200 and other electrical components. Meanwhile, it is also beneficial to improving the assembly efficiency of the tray and other components and shortening the production beat.

[0042] In some embodiments of the present utility model, such as Figure 2As shown, the beam structure 100 further includes an insulating protective layer 2. The insulating protective layer 2 is pasted on the beam body 1 and is used to block the open mouth of the receiving groove 13, playing a protective role for the electrical connectors 200 in the receiving groove 13, separating the electrical connectors 200 from other electrical components and insulating them, so as to avoid short circuits and the like caused by the contact between the electrical connectors 200 and other electrical components. Among them, the insulating protective layer 2 has the characteristics of high temperature resistance and fire protection, playing a certain heat insulation role for the electrical connectors 200 in the receiving groove 13, and can provide a good temperature environment for the electrical connectors 200 in the receiving groove 13.

[0043] Optionally, the insulating protective layer 2 can be made of mica or Pi (Polyimide). The insulating protective layer 2 made of mica or Pi (Polyimide) has good electrical insulation, high temperature resistance and flame retardance. Of course, the insulating protective layer 2 can also be made of other materials with the same or similar characteristics.

[0044] For example, as Figure 2 shown, the open mouth of the receiving groove 13 is arranged opposite to the explosion-proof valve of the battery cell in the battery pack. Then, it is necessary to paste the insulating protective layer 2 on the open mouth of the receiving groove 13 to play a protective role for the electrical connectors 200 in the receiving groove 13. When the explosion-proof valve of the battery cell in the battery pack releases pressure, it plays a protective and heat insulation role for the electrical connectors 200 in the receiving groove 13, avoiding damage to the electrical connectors 200 in the receiving groove 13. If the open mouth of the receiving groove 13 is not arranged opposite to the explosion-proof valve of the battery cell in the battery pack, the insulating protective layer 2 may not be pasted on the open mouth of the receiving groove 13.

[0045] In some embodiments of the present invention, in the length direction of the beam body 1, the receiving groove 13 extends linearly or curvilinearly. For example, as Figure 1 shown, in the length direction of the beam body 1, the receiving groove 13 extends linearly, then the structure of the receiving groove 13 is simple and easy to process. If the receiving groove 13 hinders the assembly of the tray and other components, the receiving groove 13 can extend curvilinearly in the length direction of the beam body 1 to avoid other components, preventing the electrical connectors 200 from contacting other electrical components, and ensuring the safety and reliability of the electrical connectors 200 and other electrical components.

[0046] In some embodiments of the present invention, as Figure 2 shown, the adjacent two inner walls of the receiving groove 13 are connected by an arc surface for protecting the electrical connectors 200. During the process of placing the electrical connectors 200 into the receiving groove 13, it can prevent damage to the electrical connectors 200.

[0047] In some embodiments of the present invention, as Figure 2As shown, the beam body 1 includes a main body portion 11 and a limiting portion 12. The main body portion 11 is provided with the limiting portion 12 on at least one of the two sides in the thickness direction of the beam body 1. A receiving groove 13 is defined between the limiting portion 12 and the main body portion 11. It is understandable that the limiting portion 12 can be provided on only one of the two sides in the thickness direction of the beam body 1, or can be provided on both sides of the thickness direction of the beam body 1. The limiting portion 12 protrudes from the main body portion 11. The main body portion 11 and the limiting portion 12 jointly define the receiving groove 13. The receiving groove 13 can be adapted to the electrical connector 200. The limiting portion 12 can separate the electrical connector 200 from other components, ensuring the safety and reliability of the electrical connector 200 and other components.

[0048] In some embodiments of the present invention, Figure 2 As shown, the stopper 12 does not extend beyond the thickness of the main body 11, preventing interference with the assembly of the tray and other components. For example, during battery pack assembly, the tray is snapped onto the battery pack perpendicular to the tray's bottom wall. The outermost edge of the stopper 12 in the thickness direction of the main body 11 does not exceed the overall width of the main body 11, preventing interference with the inverted assembly of the battery pack.

[0049] In some embodiments of the present invention, Figure 2 As shown, the main body 11 includes a body portion 111 and a sealing portion 112 .

[0050] Specifically, the limiting portion 12 is located on at least one of the two sides of the main body 111 along the thickness direction of the beam body 1 and is connected to the main body 111. It is understood that the limiting portion 12 can be provided on only one of the two sides along the thickness direction of the main body 111, or it can be provided on both sides of the main body 111 in the thickness direction. The main body 111 and the limiting portion 12 jointly define a receiving groove 13, which is adapted to accommodate the electrical connector 200. The limiting portion 12 can separate the electrical connector 200 from other components, ensuring the safety and reliability of the electrical connector 200 and other components.

[0051] The main body 111 has sealing portions 112 on both sides along the thickness direction of the beam body 1. The sealing portion 112 is located at one end of the main body 111 along the width direction of the beam body 1 and is spaced apart from the limiting portion 12. The sealing portion 112, the main body 111, and the limiting portion 12 define a receiving groove 13. The sealing portion 112 can effectively limit the electrical connector 200 and prevent the electrical connector 200 from falling out of the receiving groove 13. In the width direction of the beam structure 100, the sealing portion 112 is connected to the end of the main body 111 facing away from the bottom wall of the tray. Furthermore, a glue groove 1121 is provided on the side of the sealing portion 112 facing away from the bottom wall of the tray. When the beam body 1 is assembled and connected to the upper cover, the glue layer in the glue groove 1121 on the sealing portion 112 can tightly fit the upper cover, ensuring a secure and tight connection between the beam body 1 and the upper cover.

[0052] In addition, the above-mentioned insulating protective layer 2 is adhered to the side of the sealing part 112 close to the accommodating groove 13 and the side of the limiting part 12 away from the accommodating groove 13, which can ensure that the insulating protective layer 2 is firmly and reliably adhered to the beam body 1. The insulating protective layer 2 is used to seal the open mouth of the accommodating groove 13 and protect the electrical connector 200 in the accommodating groove 13.

[0053] In some embodiments of the present invention, Figure 2 As shown, the limiting portion 12 includes a first section 121 and a second section 122. The first section 121 is connected to the main body 111, so that the limiting portion 12 and the main body 111 are connected as a whole, ensuring that the limiting portion 12 and the main body 111 are securely and reliably connected. The second section 122 is connected to one end of the first section 121 that is away from the main body 111, and the other end extends toward the sealing portion 112 and is spaced apart from the sealing portion 112. The sealing portion 112, the main body 111 and the limiting portion 12 jointly define a receiving groove 13. This can simplify the structure and processing technology of the limiting portion 12, and in combination with the sealing portion 112, the electrical connector 200 can be better protected and limited. The limiting portion 12 is L-shaped as a whole, and the gap between the second section 122 of the limiting portion 12 and the sealing portion 112 is the open mouth of the receiving groove 13, thereby allowing the electrical connector 200 to be assembled into the receiving groove 13. The receiving groove 13 can be adapted to the electrical connector 200 , and the limiting portion 12 can separate the electrical connector 200 from other components, thereby ensuring the safety and reliability of the electrical connector 200 and other components.

[0054] The following describes a tray according to an embodiment of the present invention.

[0055] The tray according to the embodiment of the present invention includes a tray body and the beam structure 100 described above.

[0056] Specifically, beam structure 100 is provided within the tray body, dividing the interior space into multiple cavities for accommodating battery packs. The width of beam structure 100 is perpendicular to the bottom wall of the tray body. For example, at least one cavity for accommodating a battery pack is provided on each side of beam structure 100 in the thickness direction. A battery pack comprises multiple cells, which are arranged along the length of beam structure 100. This facilitates assembly of the tray and battery packs and effectively allocates the volumetric space within the tray.

[0057] According to the pallet of the embodiment of the present invention, by adding a receiving groove 13 on at least one of the two sides in the thickness direction of the beam body 1, the electrical connector 200 is placed in the receiving groove 13, which can improve the volume utilization rate in the pallet, and avoid contact between the electrical connector 200 and other electrical components, thereby ensuring the safety and reliability of the electrical connector 200 and other electrical components. At the same time, it is also beneficial to improve the assembly efficiency of the pallet and other components and shorten the production cycle.

[0058] In some embodiments of the present utility model, the beam structure 100 extends along the length direction of the tray body; or, the beam structure 100 extends along the width direction of the tray body; or, there are multiple beam structures 100 including a first beam structure and a second beam structure, the first beam structure extends along the length direction of the tray body, and the second beam structure extends along the width direction of the tray body.

[0059] It can be understood that the beam structure 100 in the tray can only extend along the length direction of the tray body, and the beam structure 100 can be one or multiple spaced apart along the width direction of the tray body. The beam structure 100 in the tray can also only extend along the width direction of the tray body, and the beam structure 100 can be one or multiple spaced apart along the length direction of the tray body. The beam structure 100 in the tray can also be multiple and simultaneously include a first beam structure extending along the length direction of the tray body and a second beam structure extending along the width direction, where the first beam structure can be one or multiple spaced apart along the width direction of the tray body, and the second beam structure can be one or multiple spaced apart along the length direction of the tray body.

[0060] The beam structure 100 in the tray body divides the volume space in the tray body into multiple cavities for placing battery packs. The multiple battery cells of the battery pack can be arranged along the length direction or the thickness direction of the beam structure 100, so that the battery pack and the beam structure 100 can jointly and reasonably allocate the volume space in the tray body, improving the space utilization rate in the tray body.

[0061] The following describes the battery pack according to the embodiments of the present utility model.

[0062] The battery pack according to the embodiments of the present utility model includes the above-mentioned tray, battery pack, upper cover, and electrical connector 200. A battery pack is provided in each cavity. The multiple battery cells of the battery pack can be arranged along the length direction or the thickness direction of the beam structure 100, and a receiving groove 13 is provided on the beam structure 100, and the electrical connector 200 is assembled into the receiving groove 13, so that the battery pack and the beam structure 100 can jointly and reasonably allocate the volume space in the tray body, improving the space utilization rate in the tray body. The upper cover is covered above the tray, facilitating the assembly of the upper cover with the tray and the battery pack. The electrical connector 200 is provided in the receiving groove 13 and extends along the length direction of the receiving groove 13, ensuring the safety and reliability of the electrical connector 200 and other electrical components.

[0063] For the battery pack according to the embodiments of the present utility model, by adding at least one receiving groove 13 on at least one side of the two sides in the thickness direction of the beam body 1 and placing the electrical connector 200 in the receiving groove 13, the volume utilization rate in the tray can be improved, and at the same time, the electrical connector 200 is prevented from contacting other electrical components, ensuring the safety and reliability of the electrical connector 200 and other electrical components. Also, it is beneficial to improve the assembly efficiency of the tray and other components and shorten the production beat.

[0064] In some embodiments of the present utility model, there is an adhesive layer between the battery pack and the upper cover. In the depth direction of the disc body, the difference between the size of the beam structure 100 and the size of the battery pack is the same as the thickness of the adhesive layer. The adhesive layer can be placed between the battery pack and the upper cover to prevent a large gap between the battery pack and the upper cover, thereby avoiding the risk of the adhesive layer peeling off from the battery pack or the upper cover, and ensuring reliable and firm connection between the battery pack and the upper cover.

[0065] In some embodiments of the present utility model, fixing holes are provided on the inner wall of the receiving groove 13 at intervals along the length direction of the receiving groove 13, and fixing members are provided on the electrical connector 200 at intervals along the length direction of the electrical connector 200. The plurality of fixing members are respectively fixed in the plurality of fixing holes. The electrical connector 200 in the receiving groove 13 can be fixed to prevent the size of the receiving groove 13 from being too large and the electrical connector 200 from shaking in the receiving groove 13, ensuring the reliability of the fixation of the electrical connector 200.

[0066] In some embodiments of the present utility model, as Figure 3 shown, in the width direction of the beam body 1, the opening size of the receiving groove 13 is x, and the size of the electrical connector 200 is h, and it satisfies: 1.2h ≤ x ≤ 1.5h. In the width direction of the beam body 1, if the opening size x of the receiving groove 13 < 1.2h, the opening size of the receiving groove 13 is too small, making it inconvenient to assemble the electrical connector 200 into the receiving groove 13. If the opening size x of the receiving groove 13 > 1.5h, the opening size of the receiving groove 13 is too large, and the electrical connector 200 may come out of the receiving groove 13. If the opening size x of the receiving groove 13 satisfies 1.2h ≤ x ≤ amounts of the receiving groove 13, while preventing the electrical connector 200 from coming out of the receiving groove 13.

[0067] In some embodiments of the present utility model, as Figure 3 shown, in the width direction of the beam body 1, the depth size of the receiving groove 13 is y, and the size of the electrical connector 200 is h, and y ≥ 2h / 3. In the width direction of the beam body 1, if the depth size y of the receiving groove 13 < 2h / 3, the depth size of the receiving groove 13 is too small, and the electrical connector 200 may come out of the receiving groove 13. If the depth size y of the receiving groove 13 satisfies y ≥ 2h / 3, the electrical connector 200 can be prevented from coming out of the receiving groove 13.

[0068] In some embodiments of the present utility model, as Figure 3As shown, in the thickness direction of the beam body 1, the size of the accommodation groove 13 is z, and the size of the electrical connector 200 is w, and it satisfies: 1.2w ≤ z ≤ 1.5w. In the thickness direction of the beam body 1, if the size z of the accommodation groove 13 < 1.2w, the size of the accommodation groove 13 is too small, which is not convenient for assembling the electrical connector 200 into the accommodation groove 13. If the size z of the accommodation groove 13 > 1.5w, the size of the accommodation groove 13 is too large, and the electrical connector 200 is likely to shake in the accommodation groove 13, affecting the performance of the battery pack. If the size z of the accommodation groove 13 satisfies 1.2w ≤ z ≤ 1.5w, while facilitating the assembly of the electrical connector 200 into the accommodation groove 13, it prevents the electrical connector 200 from shaking in the accommodation groove 13 and affecting the performance of the battery pack.

[0069] In some embodiments of the present utility model, as Figure 3 shown, one or more electrical connectors 200 are provided in the accommodation groove 13. Only one electrical connector 200 can be provided in the accommodation groove 13, or multiple electrical connectors 200 can be provided. And the cross-sectional size of the accommodation groove 13 can be designed according to the superposition of the cross-sections of the multiple electrical connectors 200, so that the accommodation groove 13 is adapted to the multiple electrical connectors 200, which can further improve the adaptability between the electrical connector 200 and the accommodation groove 13. It can be understood that when one electrical connector 200 is provided in the accommodation groove 13, the above size setting is defined according to the size of one electrical connector 200. When multiple electrical connectors 200 are provided in the accommodation groove 13, according to the arrangement mode of the multiple electrical connectors 200, in the thickness direction of the beam body 1, the size of the accommodation groove 13 is z and / or in the width direction of the beam body 1, the depth size y of the accommodation groove 13 needs to be defined according to the superposition of the sizes of the multiple electrical connectors 200.

[0070] The electrical equipment according to the embodiment of the present utility model includes the above-mentioned battery pack. The electrical equipment can be a vehicle, an aircraft, an energy storage device, a computer, etc.

[0071] The electrical equipment according to the embodiment of the present utility model can improve the volume utilization rate in the tray by adding the accommodation groove 13 on at least one side of the two sides in the thickness direction of the beam body 1 and placing the electrical connector 200 in the accommodation groove 13.
