[0045] The battery tray 100, power battery pack 1000 and vehicle according to the embodiments of the present invention will be described below with reference to the drawings.

[0046] Refer to Figure 1 and Figure 2, the battery tray 100 according to an embodiment of the first aspect of the present utility model includes a receiving space 10a for receiving a battery and a partition beam 30. The partition beam 30 is used to divide the receiving space 10a into at least two receiving units 10b; a first exhaust passage 30a is provided on the partition beam 30, and the first exhaust passage 30a is used to communicate one receiving unit 10b with the outside of the battery tray.

[0047] Specifically, referring to Figure 1 and Figure 2 , the battery tray 100 in the embodiment of the present utility model includes a partition beam 30. The partition beam 30 divides the receiving space 10a into at least two receiving units 10b. The partition beam 30 divides the receiving space 10a, which is convenient for the partition setting of the battery module 200 and is beneficial to the partition management of the battery module 200, improving the use safety of the battery pack. The partition beam 30 can be one, two, four, seven, etc. The shapes and volumes of at least two receiving units 10b can be the same or different.

[0048] A first exhaust passage 30a is provided on the partition beam 30. The first exhaust passage 30a communicates one receiving unit 10b with the outside of the battery tray 100. In this way, the first exhaust passage 30a can communicate the receiving unit 10b with the outside of the battery tray 100. In this way, when the battery module 200 has a thermal runaway, the smoke can be discharged through the first exhaust passage 30a, improving the use safety of the battery module 200.

[0049] Thus, referring to Figure 1 and Figure 2 , for the battery tray 100 according to the present utility model, by providing the first exhaust passage 30a on the partition beam 30, the partition beam 30 not only plays a partitioning role, but also can discharge the smoke when the battery module 200 has a thermal runaway, improving the use safety of the battery module 200.

[0050] In some embodiments of the present utility model, at least two mutually isolated first exhaust passages 30a are provided on the partition beam 30.

When one battery module 200 has a thermal runaway, it will not affect the normal use of other battery modules 200, ensuring the normal use of the battery pack and improving the use safety of the battery pack.

[0052] In some embodiments of the present utility model, at least two exhaust holes 30c are provided on the partition beam 30, and the exhaust holes 30c communicate one receiving unit 10b and one first exhaust passage 30a.

[0053] By providing exhaust holes in the partition beam 30 to connect the accommodation unit 10b and a first exhaust passage 30a, the structure is simple and easy to set up.

[0054] An accommodation unit 10b and a first exhaust passage 30a can be connected through an exhaust hole 30c, or two or more exhaust holes 30c.

[0055] In some embodiments of the present utility model, the partition beam 30 has a channel cavity, and the channel cavity is divided into at least two mutually isolated first exhaust passages 30a by a partition plate.

[0056] By dividing the channel cavity into at least two mutually isolated first exhaust passages 30a by a partition plate, the structure is simple and easy to set up.

[0057] The partition plate can divide the channel cavity into at least two mutually isolated first exhaust passages 30a arranged along the height direction or the width direction of the partition beam 30. Of course, other division methods can also be used.

[0058] In some embodiments of the present utility model, referring to Figure 1 and Figure 2 , the partition beam 30 includes a partition cross beam 31 and a partition longitudinal beam 32, and the first exhaust passage 30a is arranged on the partition cross beam 31; the partition longitudinal beam 32 is connected to the middle section of the partition cross beam 31, and the partition longitudinal beam 32 and the partition cross beam 31 together divide an accommodation unit 10b into at least two sub-accommodation units 10b1.

[0059] By providing the partition cross beam 31 and the partition longitudinal beam 32, the accommodation space 10a can be divided into an appropriate number of sub-accommodation units 10b1 for installing the battery module 200.

[0060] In the solution of the present application, the battery tray 100 is divided into six accommodation units 10b by a partition longitudinal beam 32 and three partition cross beams 31, and the first exhaust passage 30a is arranged on the partition cross beam 31, shortening the exhaust path and simplifying the setting of the exhaust passage.

[0061] Of course, the present application is not limited to this. In other embodiments, the first exhaust passage 30a can also be arranged on the partition longitudinal beam 32 or on both the partition cross beam 31 and the partition longitudinal beam 32.

[0062] In some embodiments of the present utility model, a first card slot 31a is provided on the partition cross beam 31, a second card slot is provided on the partition longitudinal beam 32, and the partition cross beam 31 and the partition longitudinal beam 32 are connected through the first card slot 31a and the second card slot.

[0063] Specifically, the first card slot 31a passes through the second card slot and is connected to the partition longitudinal beam 32, and the second card slot passes through the first card slot and is connected to the partition cross beam 31.

[0064] Of course, the present application is not limited to this, and the partition cross beam 31 and the partition longitudinal beam 32 can also be connected in other ways.

[0065] In some embodiments of the present utility model, the battery tray further includes a bottom plate 10 and side beams 20. The side beams 20 are connected to the bottom plate 10 and form a certain angle with the bottom plate 10 to enclose an accommodation space 10a with the bottom plate 10; the partition beam 30 is connected to the bottom plate 10 and the side beams 20.

[0066] Specifically, the bottom plate 10 is used to support the battery module 200. The shape of the bottom plate 10 is not limited and can be quadrilateral, polygonal, circular, etc.

[0067] The side beam 20 is connected to the bottom plate 10, specifically, it can be connected to the circumference of the bottom plate 10, etc., for protecting the battery module 200 on the side. The side beam 20 forms a certain angle with the bottom plate 10. In this way, an accommodation space 10a can be formed between the side beam 20 and the bottom plate 10 to accommodate the battery module 200. The angle between the side beam 20 and the bottom plate 10 can be an acute angle, a right angle, an obtuse angle, etc. Preferably, the angle between the side beam 20 and the bottom plate 10 is a right angle, so that the accommodation space 10a can be fully utilized and the volume of the battery tray 100 is reduced.

[0068] In some embodiments, referring to Figure 1 and Figure 3 , the bottom plate 10 is quadrilateral; the side beam 20 includes two first side beams 21 arranged oppositely and two second side beams 22 arranged oppositely; the second exhaust passage 20a is provided in the first side beam 21.

[0069] The bottom plate 10 is set as quadrilateral, which is beneficial to improving the utilization rate of the accommodation space 10a. Specifically, the bottom plate 10 can be set as a rectangle, a square, a trapezoid, a parallelogram, etc. Preferably, the bottom plate 10 is set as a rectangle.

[0070] The side beam 20 includes two first side beams 21 arranged oppositely and two second side beams 22 arranged oppositely. Specifically, the first side beam 21 and the second side beam 22 are respectively the length and width of the bottom plate 10. Of course, the first side beam 21 and the second side beam 22 are respectively the width and length of the bottom plate 10.

[0071] In some embodiments of the present utility model, referring to Figure 3 , a second exhaust passage 20a is provided on the side beam 20, and the first exhaust passage 30a is communicated with the outside of the battery tray 100 through the second exhaust passage 20a.

[0072] By providing a second exhaust passage 20a on the side beam 20, the first exhaust passage 30a is communicated with the outside of the battery tray 100. In this way, the smoke can sequentially pass through the first exhaust passage 30a and the second exhaust passage 20a and then be discharged to the outside of the battery tray 100. The first exhaust passage 30a is communicated with the outside of the battery tray 100 through the second exhaust passage 20a, so that the exhaust path can be unified.

[0073] In some embodiments, at least two second exhaust passages 20a are provided on the side beam 20, and each second exhaust passage 20a communicates one accommodating unit 10b with the outside of the battery tray 100. In this way, each accommodating unit 10b can be communicated with the outside of the battery tray 100 through the side beam 20, further improving the exhaust rate when the battery module 200 undergoes thermal runaway and enhancing the use safety of the battery pack.

[0074] Of course, the present application is not limited thereto. In other embodiments, the first exhaust passage 30a and the second exhaust passage 20a may not be communicated, and both the first exhaust passage 30a and the second exhaust passage are independently communicated with the outside of the battery tray 100.

[0075] In some embodiments, each second exhaust passage 20a communicates one accommodating unit 10b with the outside of the battery tray 100. In this way, the emission efficiency of the smoke in the accommodating unit 10b is improved, and the use safety of the battery is enhanced.

[0076] The second exhaust passage 20a is provided on the first side beam 21 so as to be adjacent to the accommodating unit 10b, facilitating the communication between the accommodating unit 10b. Of course, the second exhaust passage 20a may also be provided on the second side beam 22 or both the first side beam 21 and the second side beam 22. There is no limitation here as long as it is convenient to directly communicate the accommodating unit 10b with the second exhaust passage 20a for exhaust.

[0077] In some embodiments of the present utility model, referring to Figure 3 and Figure 4 , the side beam 20 is provided with a plurality of second exhaust passages 20a arranged along the extending direction of the side beam 20. The plurality of second exhaust passages 20a are spaced apart, and the plurality of second exhaust passages 20a are arranged in one-to-one correspondence with the plurality of first exhaust passages 30a.

[0078] Specifically, the second exhaust passage 20a is provided on the first side beam 21. Of course, the second exhaust passage 20a may also be provided on the second side beam 22.

[0079] Arranging multiple second exhaust channels 20a at intervals in the height direction of the first side beam 21 and extending along the extending direction of the first side beam 21 can improve the structural strength of the first side beam 21 and enhance the protection of the battery module 200. Setting multiple second exhaust channels 20a facilitates ensuring that each accommodation unit 10b corresponds to one second exhaust channel 20a. It should be noted that the number of second exhaust channels 20a should be greater than or equal to the number of accommodation units 10b to ensure that each accommodation unit 10b corresponds to one second exhaust channel 20a.

[0080] Specifically, the second exhaust channels 20a can be multiple exhaust pipes arranged inside the first side beam 21 and along the height direction of the first side beam 21, or the interior of the first side beam 21 can be divided into multiple channels, etc.

[0081] In some embodiments of the present utility model, referring to Figure 3 and Figure 4 , the side beam 20 includes multiple partition ribs 21a, and the multiple partition ribs 21a are arranged at intervals in the height direction of the side beam 20 to divide the interior of the side beam 20 into multiple second exhaust channels 20a.

[0082] Dividing the interior of the side beam 20 into multiple second exhaust channels 20a by the partition ribs 21a improves the space utilization rate inside the side beam 20. On the premise that the number of second exhaust channels 20a is the same, the inner diameter of each second exhaust channel 20a is increased, the exhaust rate is improved, and the use safety of the battery pack is enhanced.

[0083] Specifically, the partition ribs 21a are arranged on the first side beam 21, and both ends of the partition ribs 21a are respectively connected to two second side beams 22 to ensure that the multiple second exhaust channels 20a are not connected.

[0084] In some embodiments of the present utility model, referring to Figure 4 and Figure 5 , the second exhaust channel 20a includes a first air outlet 22a, and the opening direction of the first air outlet 22a is the extending direction of the side beam 20.

[0085] Setting the opening direction of the first air outlet 22a along the extending direction of the side beam 20 makes the emission direction of the smoke and steam along the extending direction of the side beam 20. In this way, the heat is not easily conducted above the battery pack. Especially when there is a seat above the battery pack, it will not affect the passengers on the seat.

[0086] Specifically, the first air outlet 22a is arranged on the second side beam 22. Of course, the first air outlet 22a can also be arranged along the extending direction of the second side beam 22.

[0087] In some embodiments of the present utility model, referring to Figure 3 and Figure 4, along the extending direction of the side beam 20, the side beam 20 includes at least two segmented side beams 211, and each segmented side beam 211 corresponds to a sub-accommodating unit 10b1; the segmented side beam 211 is provided with a first air inlet hole 20b and a second air inlet hole 20c, the first air inlet hole 20b communicates the first exhaust passage 30a with the second exhaust passage 20a, and the second air inlet hole 20c communicates the accommodating unit 10b with the second exhaust passage 20a.

[0088] By providing at least two segmented side beams 211 respectively corresponding to an accommodating unit 10b, and each segmented side beam 211 is provided with a first air inlet hole 20b and a second air inlet hole 20c, the accommodating unit 10b is communicated with the second exhaust passage 20a through the second air inlet hole 20c, and the first air inlet hole 20b communicates the first exhaust passage 30a with the second exhaust passage 20a, so that the smoke and steam in the accommodating unit 10b can enter the second exhaust passage 20a through the first air inlet hole 20b and the second air inlet hole 20c, and is discharged to the outside of the battery tray 100 through the second exhaust passage 20a.

[0089] Specifically, the number of the first exhaust passages 30a of each partition cross beam 31 is the same as the number of the adjacent accommodating units 10b. The partition cross beam 31 is provided with a third air inlet hole on the side facing the accommodating unit 10b, each third air inlet hole communicates a first exhaust passage 30a with an accommodating unit 10b, and multiple third air outlet holes can be provided in each accommodating unit 10b.

[0090] In some embodiments of the present invention, referring to Figure 3 and Figure 4 , the first air inlet hole 20b and the second air inlet hole 20c of each segmented side beam 211 communicate with the second exhaust passage 20a at the same height, and the first air inlet holes 20b of at least two segmented side beams 211 communicate with the second exhaust passages 20a at different heights.

[0091] The first air inlet hole 20b and the second air inlet hole 20c of each segmented side beam 211 communicate with the second exhaust passage 20a at the same height, so that no matter whether an accommodating unit 10b exhausts through the first exhaust passage 30a or the second passage, it finally discharges from the second exhaust passage 20a at the same height; the first air inlet holes 20b of at least two segmented side beams 211 communicate with the second exhaust passages 20a at different heights, so that at least two accommodating units 10b correspond to the second exhaust passages 20a at different heights, and the accommodating unit 10b corresponds to the second exhaust passage 20a one by one, ensuring that the exhausts between the accommodating units 10b do not affect each other.

[0092] Of course, it can be understood that the first air inlet holes 20b and the second air inlet holes 20c of each segmented side beam 211 can also communicate with the second exhaust channels 20a at different heights. At this time, the first air inlet holes 20b and the second air inlet holes 20c of at least two segmented side beams 211 respectively communicate with the second exhaust channels 20a at different heights. For example, the first air inlet hole 20b and the second air inlet hole 20c of the front segmented side beam 211 respectively communicate with the second exhaust channels 20a at the first height and the second height, and the first air inlet hole 20b and the second air inlet hole 20c of the rear segmented side beam 211 respectively communicate with the second exhaust channels 20a at the third height and the fourth height.

[0093] Alternatively, the first air inlet holes 20b and / or the second air inlet holes 20c of at least two segmented side beams 211 are located in the second exhaust channels 20a at the same height. The second exhaust channels 20a can be divided into a front exhaust channel and a rear exhaust channel by arranging partition blocks 21b in the exhaust channels, so as to realize the one-to-one correspondence between different accommodation units 10b and the outside of the tray.

[0094] In some embodiments, referring to Figure 3 、 Figure 4 and Figure 8 ,the first side beam 21 includes at least three segmented side beams 211; the second air inlet holes 20c of the at least three segmented side beams 211 all communicate with the second exhaust channels 20a at the first height. The second exhaust channels 20a at the first height are separated into a front side beam exhaust section 20a1, a middle side beam exhaust section 20a2, and a rear side beam exhaust section 20a3 by at least two partition blocks 21b. The second air inlet holes 20c of the at least three segmented side beams 211 respectively communicate with the front side beam exhaust section 20a1, the middle side beam exhaust section 20a2, and the rear side beam exhaust section 20a3, and the middle side beam exhaust section 20a2 communicates with the second exhaust channels 20a at the second height.

[0095] Dividing the first side beam 21 into at least three segmented side beams 211 increases the number of battery modules 200 that the battery tray 100 can accommodate. The second air inlet holes 20c of the at least three segmented side beams 211 all communicate with the second exhaust channels 20a at the first height, which is convenient for manufacturing the partition cross beam 31. The partition cross beam 31 does not need to be provided with second air inlet holes 20c at different heights and is convenient for installation.

[0096] Separated into a front side beam exhaust section 20a1, a middle side beam exhaust section 20a2, and a rear side beam exhaust section 20a3 by at least two partition blocks 21b, so that even if the second air inlet holes 20c of the at least three segmented side beams 211 communicate with the second exhaust channels 20a at the same height, the exhaust of each other will not be affected. Among them, the front side beam exhaust section 20a1 and the rear side beam exhaust section 20a3 are respectively discharged from the first air outlet at both ends of the first side beam 21, referring to Figure 6 and Figure 7, the exhaust section 20a2 of the middle side beam communicates with the second exhaust passage 20a of the second height through the communication hole 20d and is discharged from the first air outlet hole 22a of the second exhaust passage 20a, thus ensuring that the exhausts of at least three segmented side beams 211 do not affect each other. Among them, one or more communication holes 20d can be provided, etc.

[0097] It can be understood that the position setting of the first air inlet hole 20b has a relatively low production difficulty. Therefore, the first air inlet holes 20b of at least three segmented side beams 211 can be respectively communicated with the second exhaust passages 20a of different heights, simplifying the structure of the first side beam 21. It should be noted that when the first air inlet holes 20b and the second air inlet holes 20c of different segmented side beams 211 are in the second exhaust passage 20a at the same height, they can be separated by the partition block 21b. Of course, the heights of the first air inlet holes 20b can also be set to be the same, and the above separation logic can be adopted for separation to ensure that the exhausts between different accommodating units 10b do not affect each other.

[0098] By separating the second exhaust passage 20a through the partition block 21b, the number of the second exhaust passages 20a can be reduced, the inner diameter of a single second exhaust passage 20a can be increased, the exhaust rate can be improved, and the use safety can be improved.
