[0034] The embodiments of the present utility model will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model will be described in detail below.

[0035] Reference is made below to Figures 1 - 8 to describe the battery tray 100 according to an embodiment of the present utility model. A battery pack including the above battery tray 100 is also proposed.

[0036] In the present utility model, the length direction of the lifting lug 20 is Figures 2 - 8 the first direction of Figures 2 - 8 and the width direction of the lifting lug 20 is Figures 2 - 8 the second direction of

[0037] As Figure 1 and Figure 2 shown, the battery tray 100 includes: a tray 10 and a plurality of lifting lugs 20. The tray 10 includes: a bottom plate 11 and side plates 12. The plurality of lifting lugs 20 are connected to the outside of the side plates 12 at intervals. The bottom plate 11 and the side plates 12 are connected to each other. The side plates 12 are arranged along the circumference of the bottom plate 11 and extend upward, so that the side plates 12 and the bottom plate 11 jointly define a receiving space for installing at least one battery or battery module in the receiving space, so that the tray 10 can protect and bear the weight of the battery or battery module.

[0038] In some embodiments, there may be ten lifting lugs 20, five of which are arranged on one side of the tray 10 in the width direction and are arranged at intervals in the length direction; the other five lifting lugs 20 are arranged on the other side of the tray 10 in the width direction and are arranged at intervals in the length direction.

[0039] The lifting lug 20 includes: two first side walls 21 and four second side walls 22. The two first side walls 21 are arranged opposite to each other in the height direction. The four second side walls 22 are respectively arranged on both sides of the two first side walls 21 and are inclined relative to the height direction. The four second side walls 22 and the two first side walls 21 enclose a cavity. Specifically, the second side wall 22 is inclined relative to the height direction, that is, the second side wall 22 is inclined relative to the third direction (as Figures 3 - 8 shown). As Figure 2 shown, the second side wall 22 is connected to the side plate 12. While ensuring the connection strength between the lifting lug 20 and the side plate 12, compared with the lifting lug 20 with a right-angled corner, the material used can be reduced, ensuring the lightweight of the battery tray 100.

[0040] For example, the lifting lug 20 is a hollow structure, which can reduce the mass of the lifting lug 20, facilitate the lightweight design of the battery tray 100, and reduce costs at the same time.

[0041] In addition, there may be four second side walls 22. The lug 20 has two first side walls 21 and four second side walls 22. The two first side walls 21 are arranged perpendicular to the height direction, and the second side walls 22 are all arranged obliquely with respect to the height direction. That is, the cross-section of the lug 20 can be hexagonal, for example, a double trapezoidal structure with the bottom sides connected. The second side walls 22 that are inclined with respect to the height direction support the first side walls 21, improving the structural strength of the lug 20; compared with the lug 20 with right-angled corners in the prior art, the material consumption can be reduced, ensuring the lightweight of the battery tray 100.

[0042] Two of the second side walls 22 are located on one side of the first side wall 21. Two of the second side walls 22 are arranged in sequence along the height direction and are connected to each other. The upper end of the second side wall 22 located above is connected to one end of one of the first side walls 21, and the lower end of the second side wall 22 located below is connected to one end of the other first side wall 21; the other two second side walls 22 are located on the other side of the first side wall 21. The other two second side walls 22 are arranged in sequence along the height direction and are connected to each other. The upper end of the second side wall 22 located above is connected to the other end of one of the first side walls 21, and the lower part of the second side wall 22 located below is connected to the other end of the other first side wall 21. The second side walls 22 are obliquely arranged and are connected to the side plate 12. While ensuring the connection strength between the lug 20 and the side plate 12, compared with the lug 20 with right-angled corners in the prior art, the material consumption can be reduced, ensuring the lightweight of the battery tray 100.

[0043] Thus, the second side walls 22 being inclined with respect to the height direction can support the first side walls 21, improving the structural rigidity and durability of the lug 20; compared with the lug 20 with right-angled corners in the prior art, the material consumption can be reduced, realizing the lightweight of the battery tray 100.

[0044] In some embodiments, a plurality of reinforcing ribs are arranged in the cavity. The length directions of the plurality of reinforcing ribs are the same as the length direction of the lug 20. That is to say, the length directions of the plurality of reinforcing ribs are the first direction, and the inner ends of the plurality of reinforcing ribs are fixedly connected to the side plate 12 of the tray 10 body. The reinforcing ribs are arranged in the hollow structure of the lug 20, effectively improving the structural strength of the lug 20, effectively and evenly dispersing the force on the lug 20, thereby further improving the anti-extrusion ability of the lug 20.

[0045] Such as Figures 2 - 8As shown, the reinforcing rib includes: at least one first reinforcing rib 23, the first reinforcing rib 23 is parallel to the first side wall 21, and both ends of the first reinforcing rib 23 are respectively connected to the second side walls 22 on both sides. The first reinforcing rib 23 is parallel to the first side wall 21, and the first reinforcing rib 23 extends along the plane formed by the width direction and the length direction of the lug 20, that is, the first reinforcing rib 23 extends along the plane formed by the first direction and the second direction. The structural strength of the lug 20 in the first direction and the second direction is improved, and the anti-extrusion ability of the lug 20 in the first direction and the second direction can be ensured.

[0046] As Figures 3 - 5 shown, the reinforcing rib further includes: at least one second reinforcing rib 24, the second reinforcing rib 24 is vertically crossed with the first reinforcing rib 23, and both ends of the second reinforcing rib 24 are respectively connected to the two first side walls 21. Specifically, the second reinforcing rib 24 is vertically crossed with the first reinforcing rib 23, that is, the second reinforcing rib 24 extends along the height direction of the lug 20, and the second reinforcing rib 24 improves the structural strength of the lug 20 in the height direction, and the anti-extrusion ability of the lug 20 in the height direction can be ensured.

[0047] As Figures 3 - 6 shown, an installation hole 26 is provided on the lug 20, a sleeve 31 is connected in the installation hole 26, an installation member is provided in the sleeve 31, and a through hole is formed in the installation member. Specifically, an installation hole 26 is formed on the lug 20, and the axis of the installation hole 26 is parallel to the height direction of the lug 20. The sleeve 31 is arranged in the installation hole 26 to ensure the structural strength of the installation hole 26 of the lug 20. When the battery tray 100 is installed, a threaded fastener such as a screw can pass through the installation hole 26 on the lug 20 to fixedly connect the battery tray 100 with the vehicle body. Thus, the installation difficulty of the battery tray 100 is simplified, and the assembly efficiency is improved.

[0048] Among them, in the length direction of the lug 20, the projection of one of the second reinforcing ribs 24 can coincide with the axis of the installation hole 26. Since the strength of the opening at the installation hole 26 is relatively weak, setting the second reinforcing rib 24 at the axis of the installation hole 26 can improve the structural strength at the installation hole 26 and improve the structural strength of the lug 20 in the height direction, and the anti-extrusion ability of the lug 20 in the height direction can be ensured.

[0049] In addition, a through hole extending along the height direction of the lug 20 is formed in the middle of the installation member. When the battery tray 100 is installed, a threaded fastener such as a screw can pass through the through hole to fixedly connect with the vehicle body, ensuring the installation stability of the battery tray 100. Optionally, the installation member can be made of a cast iron part to ensure the structural strength of the installation member and reduce the wear of the installation member.

[0050] In some alternative embodiments, the mounting member is welded or threadedly connected to the sleeve 31. When the mounting member is welded to the sleeve 31, the reliability of the fixation of the mounting member can be effectively ensured. When the mounting member is threadedly connected to the sleeve 31, it is convenient for the disassembly and assembly of the mounting member. When the mounting member is damaged, the mounting member can be removed and directly replaced without replacing the entire battery tray 100.

[0051] Referring Figures 3 - 5 As shown, there are at least two second reinforcing ribs 24, and the projections of the at least two second reinforcing ribs 24 are located within the projection of the mounting hole 26. That is to say, in the length direction, the projections of the at least two second reinforcing ribs 24 are located within the projection of the mounting hole 26. Since the strength at the mounting hole 26 is relatively weak due to the opening, setting the second reinforcing ribs 24 at the mounting hole 26 can improve the structural strength at the mounting hole 26.

[0052] In some embodiments, there are multiple second reinforcing ribs 24, and the projections of at least two second reinforcing ribs 24 are located within the projection of the mounting hole 26. That is to say, the second reinforcing ribs 24 can be two, and the projections of the two second reinforcing ribs 24 are both located within the projection of the mounting hole 26. Since the strength at the mounting hole 26 is relatively weak due to the opening, setting the second reinforcing ribs 24 at the mounting hole 26 can improve the structural strength at the mounting hole 26 and prevent the mounting hole 26 from deforming due to stress concentration when the lug 20 is connected to the vehicle body.

[0053] Furthermore, there are two second reinforcing ribs 24. In the length direction of the lug 20, the projections of the two second reinforcing ribs 24 are located within the projection of the mounting hole 26, and the two second reinforcing ribs 24 are respectively arranged on both sides of the axis of the mounting hole 26. By arranging two second reinforcing ribs 24 on both sides of the axis of the mounting hole 26, the structural strength around the mounting hole 26 can be evenly improved, and the mounting hole 26 can be prevented from deforming due to stress concentration when the lug 20 is connected to the vehicle body.

[0054] In some other embodiments, the second reinforcing ribs 24 can be three. In the length direction of the lug 20, the projections of two of the second reinforcing ribs 24 are located within the projection of the mounting hole 26, and the projection of the other second reinforcing rib 24 is located outside the projection of the mounting hole 26. The projections of two of the second reinforcing ribs 24 are located within the projection of the mounting hole 26. Since the strength at the mounting hole 26 is relatively weak due to the opening, setting two second reinforcing ribs 24 at the mounting hole 26 can improve the structural strength at the mounting hole 26 and prevent the mounting hole 26 from deforming due to stress concentration when the lug 20 is connected to the vehicle body; the projection of the other second reinforcing rib 24 is located outside the projection of the mounting hole 26, which can improve the structural strength of the area on the lug 20 other than the mounting hole 26 and enhance the anti-extrusion ability of the lug 20.

[0055] In some embodiments, there may be three second reinforcing ribs 24. In the length direction of the lug 20, the projections of two of the second reinforcing ribs 24 are located within the projection of the mounting hole 26, and the projection of the other second reinforcing rib 24 is located outside the projection of the mounting hole 26. The two second reinforcing ribs 24 are respectively arranged on both sides of the axis of the mounting hole 26. By arranging two second reinforcing ribs 24 on both sides of the axis of the mounting hole 26 respectively, the structural strength of the periphery of the mounting hole 26 is uniformly improved, and the deformation of the mounting hole 26 caused by stress concentration when the lug 20 is connected to the vehicle body is avoided; the projection of the other second reinforcing rib 24 is located outside the projection of the mounting hole 26, which can improve the structural strength of the area of the lug 20 other than the mounting hole 26 and enhance the anti-extrusion ability of the lug 20.

[0056] In this way, the arrangement positions and structural designs of the first reinforcing rib 23 and the second reinforcing rib 24 are more reasonable, the mass of the lug 20 is reduced, and on the basis of lightweight, the anti-extrusion ability of the lug 20 is improved.

[0057] According to Figures 6 - 8 As shown, the reinforcing rib further includes: at least one third reinforcing rib 25. The third reinforcing rib 25 is inclined relative to the first reinforcing rib 23, and one end of the third reinforcing rib 25 is connected to the intersection of the first reinforcing rib 23 and the second reinforcing rib 24, and the other end of the third reinforcing rib 25 is connected to the connection portion of any one of the first side wall 21 and the second side wall 22. Specifically, there may be two third reinforcing ribs 25. One end of any one of the two third reinforcing ribs 25 is connected to the intersection of the adjacent second reinforcing rib 24 and the first reinforcing rib 23, and the other end of any one of the two third reinforcing ribs 25 is connected to the connection portion of any one of the first side wall 21 and the second side wall 22. In this way, the arrangement positions and structural designs of the first reinforcing rib 23, the second reinforcing rib 24, and the third reinforcing rib 25 are more reasonable, the structural strength of the lug 20 is improved, and on the premise of improving the anti-extrusion ability, the mass of the lug 20 is reduced and the cost is lowered at the same time.

[0058] Combined with Figure 5 and Figure 8 As shown, the cross-section of the lug 20 is constructed as two trapezoidal structures with the same bottom sides connected. The other end of the third reinforcing rib 25 is connected to the vertex angle of any one of the trapezoidal structures. That is to say, the four second side walls 22 are inclined and the second side walls 22 are connected to the side plate 12. While ensuring the connection strength between the lug 20 and the side plate 12, compared with the lug 20 with a right-angled corner, the material used can be reduced to ensure the lightweight of the battery tray 100. One end of the third reinforcing rib 25 is connected to the intersection of the adjacent second reinforcing rib 24 and the first reinforcing rib 23, and the other end is connected to the vertex angle of any one of the trapezoidal structures, which improves the anti-extrusion ability of the lug 20 in the height direction.

[0059] In this way, the arrangement positions and structural designs of the first reinforcing rib 23, the second reinforcing rib 24, and the third reinforcing rib 25 are made more reasonable, improving the structural strength of the lug 20. On the premise of improving the anti-extrusion ability, the mass of the lug 20 is reduced while the cost is lowered.

[0060] In some other embodiments, the trapezoidal structure is an isosceles trapezoidal structure. That is to say, the sizes of the four second side walls 22 are the same, reducing the forming difficulty of the first reinforcing rib 23, the second reinforcing rib 24, and the third reinforcing rib 25.

[0061] In some embodiments, the battery tray 100 further includes: a positioning structure provided on at least one lug 20. Specifically, when the battery tray 100 is installed, the positioning structure on the lug 20 can be first engaged with the positioning holes on the vehicle body to ensure that the mounting holes 26 on the lug 20 can correspond to the assembly holes on the vehicle body one by one. Then, a threaded fastener such as a screw is passed through the mounting holes 26 on the lug 20 and engaged with the assembly holes on the vehicle body to realize the fixed connection between the battery tray 100 and the vehicle body. Thus, the alignment rate of the mounting holes 26 and the assembly holes can be effectively improved through the positioning structure, ensuring the reliability and accuracy of the installation of the battery tray 100, and at the same time improving the assembly efficiency of the battery tray 100.

[0062] Further, the positioning structure is a positioning pin fixedly connected to the lug 20, and the free end of the positioning pin extends upward. When the battery tray 100 is installed, since the battery tray 100 is installed from the bottom of the vehicle body upward, the positioning pin with the free end extending upward is more likely to be engaged with the positioning holes on the vehicle body, so as to ensure that the mounting holes 26 on the lug 20 correspond to the assembly holes on the vehicle body. At the same time, the structure of the positioning pin is simple and convenient for processing. In other embodiments, the positioning structure can also be a positioning hole.

[0063] In some alternative embodiments, the positioning pin is welded or threadedly connected to the lug 20. When the positioning pin is welded to the lug 20, the positioning pin can be directly welded to the top surface of the lug 20, effectively ensuring the firmness of the fixed positioning pin and being convenient for operation. When the positioning pin is threadedly connected to the lug 20, it is convenient for the disassembly and assembly of the positioning pin. When the positioning pin is damaged, the positioning pin can be removed and directly replaced without replacing the entire battery tray 100.

[0064] The battery pack according to the second aspect embodiment of the present invention includes: a battery tray 100. By adopting the battery tray 100 of the first aspect embodiment of the present invention above, while improving the structural strength of the battery tray 100, the weight reduction of the battery pack is realized.
