Referring to fig. 1 and 2, a battery frame 100 according to an embodiment of the present invention includes at least two battery holders 10, each battery holder 10 includes a holder fixing portion 11, a battery fixing portion 12, and a transition portion 13 located between the holder fixing portion 11 and the battery fixing portion 12, and a longitudinal direction of the holder fixing portion 11 intersects a longitudinal direction of the battery fixing portion 12. Each battery bracket 10 has an i-shaped cross section, a bracket fixing portion 11 is fixedly connected to the vehicle body, and a battery fixing portion 12 has a mounting surface S on which the battery 200 is mounted.

The battery frame 100 is composed of only a plurality of battery holders 10, and has a very simple structure, a very easily controlled weight, and a light weight. The battery 200 is placed on the mounting surface S of the battery fixing portion 12 of the battery tray 10, and the size thereof may exceed the size of the battery frame 100, so that the battery frame 100 can accommodate batteries 200 of different kinds and sizes, and occupies a very small space with low requirements for space, and does not affect the direction and installation of the cooling and high-voltage wiring harness. The "i" shape also provides the battery holder 10 with good strength, and the mounting surface S is formed to facilitate the mounting of the battery 200. In the present embodiment, the battery frame 100 includes two battery trays 10, and it is understood that a user may increase or decrease the number of battery trays 10 and adjust the installation distance between different battery trays 10 according to the size, weight and installation space of the battery 200, which is not specifically limited herein.

Specifically, the battery carrier 10 is manufactured by integral molding casting. The battery bracket 10 is made of cast iron or cast aluminum. The integrally formed battery bracket 10 has good mechanical performance, avoids the hidden connection danger caused by the existence of breakpoints, has mature casting process, is suitable for large-scale industrial production, and has easy control of cost. Both cast aluminum and cast iron are casting materials which are very frequently used, and have wide application range and low manufacturing cost. The battery bracket 10 made of cast iron has good rigidity and strength. In the battery holder 10 made of cast aluminum, the weight of the battery holder 10 itself is reduced due to the low density of aluminum while the rigidity and strength are ensured, which contributes to the weight reduction of the battery frame 100, and the cast aluminum has excellent anti-rusting ability and is not prone to rusting even in a complicated environment.

Further, the battery frame 100 further includes at least one bracket fixing member 112, each bracket fixing portion 11 is provided with at least one first fixing hole 111, and one end of the bracket fixing member 112 penetrates through the bracket fixing portion 11 through the first fixing hole 111 and fixes the bracket fixing portion 11 to the vehicle body. And reinforcement is done at a fixed location. Thus, the battery bracket 10 can be easily, conveniently and stably fixed to the vehicle body through the bracket fixing portion 11, and is easy to detach. In this embodiment, the number of the bracket fixing member 112 and the first fixing hole 111 is two, and in other embodiments, the number of the bracket fixing member 112 and the first fixing hole 111 is appropriately changed according to the size and the fixing position of the battery bracket 10, and is not particularly limited herein.

Further, the angle a between the connection of the bracket fixing portion 11 and the transition portion 13 is less than or equal to 180 °. At least a partial region of the transition 13 is curved. An included angle is formed between the transition part 13 and the bracket fixing part 11, so that the transition part 13 can be convenient to avoid other parts on the vehicle. Similarly, the arc design is also beneficial for the transition part 13 to avoid other parts on the vehicle, and is also beneficial for dispersing the stress of the transition part 13.

In some embodiments, the width of the battery fixing portion 12 gradually narrows in a direction toward the distal end near the proximal end of the transition portion 13. Considering that the rigidity and strength requirements of the battery fixing portion 12 from the position close to the transition portion 13 toward the distal end are gradually reduced, the contraction width does not worry that the requirements are not met, but the volume of the battery fixing portion 12 can be reduced, which contributes to controlling the overall weight, helps to achieve light weight of the battery frame 100, and also reduces the occupied space.

Further, the battery frame 100 further includes at least one battery fixing member 122, each battery fixing portion 12 is provided with at least one second fixing hole 121, and one end of the battery fixing member 122 passes through the battery fixing portion 12 through the second fixing hole 121 and is matched with the battery 200 to fix the battery 200 on the battery fixing portion 12. And reinforcement is done at a fixed location. The battery 200 can be stably fixed to the mounting surface S by the battery holder 122 and the second fixing hole 121, and the mounting and dismounting are very convenient. In this embodiment, the battery fixing member 122 and the second fixing hole 121 are two, wherein the two second fixing holes 121 are respectively close to two ends of the battery fixing portion 12, so as to stably fix the battery 200 on the mounting surface S. It is understood that in other embodiments, the number and the positions of the battery fixing member 122 and the second fixing hole 121 are appropriately changed according to the size and the fixing position of the battery bracket 10, and are not particularly limited herein.

Further, each of the battery fixing parts 12 is opened with at least one third fixing hole 123, and each of the third fixing holes 123 is used for fixing the high-voltage harness and the cooling pipe of the battery 200. The third fixing hole 123 can regulate the high-voltage wire harness and the cooling pipeline to a certain extent, so that the arrangement is prevented from being excessively messy, and meanwhile, the high-voltage wire harness and the cooling pipeline are prevented from being damaged and broken due to random shaking and even scratch with other parts or the outside.

Specifically, when the battery bracket 10 is fixed to the vehicle body, the longitudinal direction of the battery fixing portion 12 is parallel to the horizontal direction. Thus, it is convenient to smoothly mount the battery 200 on the mounting surface S of the battery fixing portion 12, and the operational stability of the battery holder 12 is ensured, thereby avoiding the uncontrollable burden on other components due to the generation of the oblique force caused by the existence of the oblique angle.

When the battery frame 100 is used, the battery carrier 10 can be fixed to the vehicle body by the carrier fixing member 112, and the battery 200 can be fixed to the mounting surface S of the battery fixing portion 12 of the battery carrier 10 by the battery fixing member 122, thereby achieving fixation to the vehicle body. After the fixing of the battery 200 is completed, the battery frame 100 does not obstruct the arrangement of the high-voltage harness and the cooling pipe, and the high-voltage harness and the cooling pipe may be fixed through the third fixing hole 123. The arrangement position of the battery bracket 10 is very flexible, the requirement on space is low, and the occupied space is small. The number of the battery brackets 10 and the installation distance between the different battery brackets 10 can be adjusted by the user according to the size of the battery 200, and both ends of the battery 200 can also be beyond the range of the battery frame 100, so the adaptability of the battery frame 100 is very strong.

The utility model also provides a vehicle, which comprises the battery frame 100 and the power battery, wherein the battery frame 100 is fixed on a vehicle frame 300 of the vehicle, and the power battery is fixed on the battery frame 100. The power battery is provided with a battery mounting frame, and the battery mounting frame is provided with a battery fixing hole corresponding to the second fixing hole 121. After one end of the battery fixing member 122 passes through the battery fixing portion 12 through the second fixing hole 121, the power battery is fixed to the battery fixing portion 12, that is, to the battery frame 100, in cooperation with the battery fixing hole. The vehicle with the battery frame 100 is convenient to disassemble and assemble the power batteries, and the vehicle can be provided with the power batteries of different models by adjusting the number and the installation distance of the battery brackets 10.
