The first mounting hole is used to be fixedly connected with the battery pack through the first fastener. A second mounting hole for a second fastener to pass through is formed on the flange. The second mounting hole is used to be fixedly connected with the bottom wall of the vehicle frame body through the second fastener;

[0005] At least one avoidance portion recessed toward a first direction is formed on the bracket body, and the avoidance portion is used to be correspondingly disposed with the side beam of the battery pack.

[0006] Optionally, at least one protruding portion protruding toward the first direction is formed on the bracket body. Along the length direction of the bracket body, the avoidance portion and the protruding portion are alternately arranged in sequence.

[0007] Optionally, a weight reduction hole is further formed on the bracket body, and the weight reduction hole penetrates the bracket body along the thickness direction of the bracket body.

[0008] Optionally, the weight reduction hole is formed on the protruding portion.

[0009] Optionally, the flanging has at least one extension, the extension is connected to the end of the protruding portion, and the extension extends in a direction opposite to the first direction. Each of the extensions is formed with the second mounting hole.

[0010] Optionally, there are a plurality of the second mounting holes, and adjacent two of the second mounting holes are spaced along the length direction of the flanging.

[0027] In addition, the "up and down direction" is defined based on the vehicle frame in the actual driving state, and specifically, reference can be made to Figure 3 the up and down direction shown, and the "length direction" is defined based on the battery pack bracket, and specifically, reference can be made to Figure 3 the length direction shown. In addition, it should be noted that the terms such as "first" and "second" are used to distinguish one element from another, and do not have an order and importance. In addition, in the description with reference to the drawings, the same reference numerals in different drawings represent the same elements.

[0028] In the description of the present disclosure, it should also be noted that, unless otherwise clearly specified and limited, the terms "arranged", "connected", "coupled", and "installed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0029] Referring Figures 1 to 3 As shown, a first aspect of the present disclosure provides a battery pack bracket 1, including a bracket body 12 and a flange 20 formed on one side of the bracket body 12. The flange 20 is arranged at an angle with the bracket body 12 and manufactured integrally. A first mounting hole 110 for a first fastener to pass through is formed on the bracket body 12. The first mounting hole 110 is used to be fastened to the battery pack 200 through the first fastener. A second mounting hole 22 for a second fastener to pass through is formed on the flange 20. The second mounting hole 22 is used to be fastened to the bottom wall of the vehicle frame body 101 through the second fastener; at least one avoidance portion 11 recessed toward the first direction is formed on the bracket body 12, and the avoidance portion 11 is used to be correspondingly arranged with the side beam 201 of the battery pack 200.

[0030] Through the above technical solution, the flange 20 and the bracket body 12 are manufactured integrally, and there is no need to provide a fastening structure to connect the flange 20 and the bracket body 12. Therefore, the overall structure of the battery pack bracket 1 is simplified, the weight of the battery pack bracket 1 is reduced, and it is convenient for production personnel to install and disassemble the battery pack 200.

[0031] As Figures 1 to 3 shown, in addition, an avoidance groove corresponding to the side beam 201 of the battery pack 200 is also formed on the bracket body 12 provided by the present disclosure. In this way, when connecting and installing and fixing the bracket body 12 and the battery pack 200, the side beam 201 of the battery pack 200 can be embedded in the avoidance groove, so that the connection between the bracket body 12 and the battery pack 200 is not restricted by the side beam 201 protruding from the outer wall of the battery pack 200, and the close contact between the bracket body 12 and the outer wall of the battery pack 200 is maintained, improving the fixing effect on the battery pack 200.

[0032] Moreover, when the battery pack bracket 1 is assembled to the vehicle frame main body 101, the flange 20 of the battery pack bracket 1 is connected to the bottom wall of the vehicle frame main body 101, that is, the battery pack bracket 1 is hung directly below the vehicle frame main body 101 in the up and down direction. Compared with the prior art in which the battery pack bracket 1 is installed on the side of the vehicle frame main body 101, on the one hand, the space occupied by the battery pack bracket 1 in the width direction of the vehicle frame main body 101 can be greatly reduced, thereby reducing the installation space of the battery pack. On the other hand, installing the battery pack in a hanging manner can also reduce the stress on the battery pack bracket 1, achieving the effect of improving the stability and service life of the battery pack bracket 1.

[0033] It should be noted that the above-mentioned flange 20 and the bracket body 12 can be integrally formed by injection molding or by sheet metal stamping. The present disclosure does not limit this.

[0034] In order to improve the connection effect between the bracket body 12 and the battery pack 200, optionally, as Figures 1 to 3 shown, a first mounting hole 110 is formed on each of the avoidance portions 11. That is to say, a plurality of first mounting holes 110 can be formed on the bracket body 12, and the plurality of first mounting holes 110 can respectively realize the fastening connection between the bracket body 12 and the vehicle frame main body 101 through a plurality of first fasteners, thereby improving the connection strength between the bracket body 12 and the battery pack 200.

[0035] It should be noted that for the embodiment in which the first connection hole is formed on the avoidance portion 11, a first mating hole can be formed on the side beam 201 of the battery pack 200. In this way, when connecting the bracket body 12 and the battery pack 200, the first fastener can sequentially pass through the first mounting hole 110 and the second mating hole on the side beam 201 accommodated in the avoidance portion 11 to realize the connection between the bracket body 12 and the side beam 201, and further realize the connection and fixation between the bracket body 12 and the battery pack 200.

[0036] Moreover, by forming the first mating hole on the side beam 201 to realize the fixation between the bracket body 12 and the battery pack 200, there is no need to open holes or provide fastening structures on the battery pack 200, so the overall structure of the battery pack 200 will not be damaged and the stability of the battery pack 200 will not be affected.

[0037] Optionally, as Figures 1 to 3As shown, at least one convex portion 21 protruding toward the first direction is formed on the bracket body 12. Along the length direction of the bracket body 12, the avoidance portion 11 and the convex portion 21 are alternately arranged in sequence. That is to say, the protruding direction of the convex portion 21 is opposite to the concave direction of the avoidance portion 11. In this way, when the bracket body 12 is fixed on the battery pack 200 (that is, when the avoidance portion 11 is buckled on the side beam 201), the convex portion 21 protrudes toward the battery pack 200. The convex portion 21 can abut against the outer wall of the battery pack 200, thereby increasing the contact area when the bracket body 12 is connected and fixed to the battery pack 200 and improving the fixing effect on the battery pack 200.

[0038] In order to further improve the fixing effect on the battery pack 200, as Figures 1 to 3 shown, in an embodiment provided by the present disclosure, a plurality of third mounting holes may be provided on the convex portion 21. The third mounting holes are used to connect with the battery pack 200 through third fasteners, thereby increasing the connection points between the bracket body 12 and the battery pack 200 and making the connection to the battery pack 200 more stable.

[0039] Optionally, as Figures 1 to 3 shown, a weight reduction hole 210 is further formed on the bracket body 12. The weight reduction hole 210 penetrates the bracket body 12 along the thickness direction of the bracket body 12. By providing the weight reduction hole 210 on the bracket body 12, the overall weight of the bracket body 12 can be reduced, and the weight of the battery pack bracket 1 can be further reduced, facilitating the lightweight of the vehicle.

[0040] As Figures 2 to 3 shown, in an embodiment provided by the present disclosure, the weight reduction hole 210 may be formed on the convex portion 21. Since there is no direct connection relationship between the convex portion 21 and the battery pack 200, forming the weight reduction hole 210 on the convex portion 21 will not affect the connection strength between the bracket body 12 and the battery pack 200.

[0041] Optionally, as Figures 1 to 3 shown, the flanging 20 has at least one extension portion 23. The extension portion 23 is connected to the end of the convex portion 21, and the extension portion 23 extends in a direction opposite to the first direction. A second mounting hole 22 is formed on each extension portion 23. When the avoidance portion 11 is buckled on the side beam 201 of the battery pack 200, since the extension portion 23 extends in a direction opposite to the first direction, the extension portion 23 can be exposed on the outside. In this way, it is more convenient for the processing personnel to install and disassemble the second mounting hole 22 provided on the extension portion 23 through the second fastener.

[0042] In addition, as Figures 1 to 3As shown, the second mounting holes 22 can also be multiple. Along the length direction of the flange 20, two adjacent second mounting holes 22 are arranged at intervals. By arranging multiple second mounting holes 22 at intervals along the length direction of the flange 20, the connection points between the extension part 23 and the vehicle frame main body 101 can be increased, thereby enhancing the connection strength between the bracket body 12 and the vehicle frame main body 101.

[0043] For the embodiment in which there are multiple second mounting holes 22, each extension part 23 can be formed with one second mounting hole 22, or can be formed with multiple second mounting holes 22. For example, in an exemplary embodiment provided by the present disclosure, the above-mentioned flange 20 can have three extension parts 23. One second mounting hole 22 is respectively arranged on the two extension parts 23 located at the edges, and three second mounting holes 22 are arranged on the extension part 23 located in the middle.

[0044] The second aspect of the present disclosure provides a vehicle frame 100, including a vehicle frame main body 101 and the battery pack bracket 1 as above. The battery pack bracket 1 is connected to the vehicle frame main body 101. The vehicle frame 100 has all the beneficial effects of the above-mentioned battery pack bracket 1, and the present disclosure does not limit this.

[0045] Optionally, the flange 20 of the battery pack bracket 1 is connected to the bottom wall of the vehicle frame main body 101, and the projection of the battery pack bracket 1 in the up-down direction is located within the projection of the vehicle frame main body 101 in the up-down direction. In this way, since the flange 20 in the present disclosure is fixedly connected to the bottom wall of the vehicle frame main body 101 through the second fastener, and the projection of the battery pack bracket 1 in the up-down direction is located within the projection of the vehicle frame main body 101 in the up-down direction, compared with the connection method directly to the side wall of the vehicle frame main body 101 in the related art, the space below the vehicle frame main body 101 can be fully utilized, and the problem that the flange 20 or the bracket body 12 protrudes in the width direction of the vehicle frame main body 101 after the flange 20 is connected to the vehicle frame main body 101 can be avoided, that is, the arrangement of the flange 20 and the bracket body 12 will not occupy or squeeze the space inside and outside the vehicle frame main body 101, so that a battery pack 200 with a larger volume can be arranged below the vehicle frame main body 101 to improve the endurance of the battery pack 200.

[0046] The third aspect of the present disclosure provides a vehicle, including the battery pack bracket 1 as above or the vehicle frame 100 as above. The vehicle has all the beneficial effects of the above-mentioned battery pack bracket 1 and vehicle frame 100, and the present disclosure does not describe this here.

[0047] It should be noted that the above-mentioned vehicle can be a hybrid vehicle or a pure electric vehicle.

[0048] The preferred embodiments of the present disclosure have been described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure. Additionally, it should be noted that, among the various specific technical features described in the above specific embodiments, they can be combined in any appropriate manner without conflict.
