[0031] Now, the present utility model will be further described in detail with reference to the drawings and embodiments. These drawings are all simplified schematic diagrams, and only illustrate the basic structure of the present utility model in a schematic manner. Therefore, they only show the components related to the present utility model.

[0032] A battery box mounting bracket, as shown in Figures 1-9 the figure, is installed on a large truck for placing the battery 23 and facilitating loading and unloading. The height of the girder 1 is greater than or equal to the height of the battery 23, and the width of the girder 1 is equal to or greater than the width of the battery 23 to ensure the placement of the battery 23. The battery box mounting bracket includes an upper battery frame 21 and a lower battery frame 22, and the battery 23 is placed in both the upper battery frame 21 and the lower battery frame 22. The lower battery frame 22 is arranged below the upper battery frame 21 and connected to the upper battery frame 21. When the upper battery frame 22 is connected to the vehicle, the lower battery frame 22 is located below the girder 1.

[0033] There are two vehicle girders 1. To ensure the strength and stability of the girders 1, reinforcing ribs are provided on the two girders 1. The reinforcing ribs connect the two girders 1, which can reinforce the girders 1 and ensure sufficient strength after the battery box mounting bracket is installed on the girders 1.

[0034] A connecting frame is provided on the vehicle girder 1 to facilitate the connection between the upper battery frame 21 and the vehicle girder 1. The connecting frame is connected to the vehicle and the girder 1. The connecting frame includes a number of frame connecting beams provided on the girder 1, and is connected to the upper battery frame 21 through the frame connecting beams.

[0035] A number of longitudinal beams 211, a number of cross beams 212 and a number of connecting beams 213 are connected to form the upper battery frame 21. The number of the longitudinal beams 211 is arranged at intervals, and the distance between two adjacent longitudinal beams 211 is equal. Of course, it can also be set to unequal distances, but it is necessary to ensure that it is greater than or equal to the width of the battery 23. Moreover, if the set distances are unequal, after the upper battery frame 21 is connected to the girder 1, it is easy to cause the upper battery frame 21 to tilt and the forces on both sides to be uneven. In this solution, four longitudinal beams 211 are provided, and the distance between two adjacent longitudinal beams 211 is equal, and the distance between two adjacent longitudinal beams 211 is greater than or equal to the width of the battery 23.

[0036] The number of the cross beams 212 is arranged at intervals, and each cross beam 212 is connected to each longitudinal beam 211. Of course, it can also be set that each cross beam is connected to two adjacent longitudinal beams 211. For example, if there are four longitudinal beams 211 arranged from left to right, and four cross beams 212 are arranged from front to back along the extension direction of the longitudinal beams 211, the first cross beam is connected to all four longitudinal beams, the second cross beam is connected to all four longitudinal beams, the third cross beam is connected to all four longitudinal beams, and the fourth cross beam is also connected to all four longitudinal beams. Or, four parallel and spaced cross beams are provided between the first longitudinal beam and the second longitudinal beam for connection, four parallel and spaced cross beams are provided between the second longitudinal beam and the third longitudinal beam for connection, and four parallel and spaced cross beams are provided between the third longitudinal beam and the fourth longitudinal beam for connection.

[0037] For the convenience of placing the battery 23 and subsequent maintenance of the battery 23, the upper battery frame 21 includes an upper layer beam and a lower layer beam. No cross beam 212 is provided in the middle of the longitudinal beam 211 of the lower layer beam, ensuring that when the upper battery frame 21 is connected to the lower battery frame, the second layer of battery 23 arranged on the lower battery frame can enter the upper battery frame 21. That is to say, a plurality of cross beams 212 are connected and arranged on the longitudinal beam 211 of the upper layer beam, and the plurality of cross beams 212 are evenly arranged along the extending direction of the longitudinal beam 211. On the longitudinal beam 211 of the lower layer beam, cross beams 212 are only arranged at both ends of the longitudinal beam 211 to ensure that the battery 23 can be placed in the upper battery frame 21.

[0038] The upper layer beam and the lower layer beam are connected by a plurality of connecting beams 213. The connecting beams 213 are arranged on the longitudinal beam 211. That is to say, both ends of the connecting beam 213 are connected to the longitudinal beam 211. The connecting beam 213 is vertically arranged with the longitudinal beam 211, and the connecting beam 213 extends in the height direction. The arrangement of the connecting beam 213 can not only be used for connection but also ensure the strength of the upper battery frame 21. The number of connecting beams 213 arranged on each longitudinal beam 211 is not limited, as long as the connection and strength are ensured. In this solution, four connecting beams 213 are arranged on each longitudinal beam 211. The length of the connecting beam 213 is greater than or equal to the height of the battery 23 to ensure the placement of the battery 23.

[0039] The upper battery frame 21 can be set as a whole, including a first battery placement space, a second battery placement space, and a third battery placement space arranged in sequence. The vehicle girder 1 passes through the second battery placement space. The upper battery frame 21 can also be set as a separated frame body. Two separated frame bodies respectively form a first battery placement space and a second battery placement space. An intermediate beam 215 is arranged on the upper battery frame 21. The intermediate beam 215 straddles the vehicle girder 1 and connects the first battery placement space and the second battery placement space to form a third battery placement space. The third battery placement space is located between the first battery placement space and the second placement space, and the vehicle girder 1 is located in the third placement space. The arrangement of the intermediate beam 215 can not only connect the first battery placement space and the second battery placement space but also strengthen the strength of the upper battery frame 21.

[0040] To ensure the strength of the upper battery frame 21, a plurality of strengthening beams are also arranged on the upper battery frame 21, and the arrangement of the strengthening beams does not affect the placement of the battery 23.

[0041] To place the battery 23, a battery placement space is provided on the upper battery frame 21. The battery placement space is formed by enclosing the longitudinal beam 211, the cross beam 212, and the connecting beam 213. At least one battery placement space is provided, and the number of battery placement spaces is preferably set to an odd number. When there is one battery placement space, there are two vehicle girders 1, and the battery 23 is located in the middle of the girder 1, hidden in the girder 1. The shape of the battery 23 can be adapted to the girder 1, allowing for a greater number of batteries 23 to be set while reducing the occupied volume of the battery mounting bracket. When there are three battery placement spaces, the middle one is the second placement space, and the first placement space and the third placement space are on both sides of the second placement space. After the upper battery frame 21 is connected to the girder 1, the girder 1 passes through the second placement space and is connected to the upper battery frame 21. At this time, the battery in the second placement space is located between the two girders 1, and the first placement space and the third placement space are on both sides of the girder 1 to ensure balance. The battery placement spaces can also be set to five, seven, or more, but it should adapt to the width of the vehicle to avoid protruding from both sides of the vehicle. One battery 23 is provided in each battery placement space.

[0042] The length direction of the battery placement space is the same as the extension direction of the girder 1, and the placement of the battery 23 is adapted to the girder 1 to ensure that more batteries 23 can be placed.

[0043] The lower battery frame 22 includes an upper layer beam, a lower layer beam, and a connecting beam 213 connecting the upper layer beam and the lower layer beam. The upper layer beam and the lower layer beam each include a number of cross beams 212 and a number of longitudinal beams 211. That is, a number of cross beams 212, a number of longitudinal beams 211, and a number of connecting beams 213 enclose to form the lower battery frame 22. The setting of the lower battery frame 22 is similar to that of the upper battery frame 21. Taking the lower layer beam as an example, a number of the longitudinal beams 211 are arranged at intervals, and the distance between two adjacent longitudinal beams 211 is equal. Of course, it can also be set to an unequal distance, but it is necessary to ensure that it is greater than or equal to the width of the battery 23. In this solution, four longitudinal beams 211 are provided, and the distance between two adjacent longitudinal beams 211 is equal, and the distance between two adjacent longitudinal beams 211 is greater than or equal to the width of the battery 23.

[0044] A number of the cross beams 212 are arranged at intervals, and each cross beam 212 is connected to each longitudinal beam 211. For example, there are four longitudinal beams 211 arranged from left to right, and four cross beams 212 are arranged from front to back along the extension direction of the longitudinal beams 211. The first cross beam is connected to all four longitudinal beams, the second cross beam is connected to all four longitudinal beams, the third cross beam is connected to all four longitudinal beams, and the fourth cross beam is also connected to all four longitudinal beams. Or, four parallel and spaced cross beams are arranged and connected between the first longitudinal beam and the second longitudinal beam, four parallel and spaced cross beams are arranged and connected between the second longitudinal beam and the third longitudinal beam, and four parallel and spaced cross beams are arranged and connected between the third longitudinal beam and the fourth longitudinal beam.

[0045] Before the battery 23 is placed completely, the middle cross beam 212 of the upper layer beam is not provided to facilitate the placement of the battery 23. After the battery 23 is placed completely, then connect the middle cross beam 212 with the longitudinal beam 211. Of course, the middle cross beam 212 of the lower layer beam can also be not provided, but the middle cross beam 212 of the lower layer beam bears all the weight of the battery 23. Therefore, the best case is to not provide the middle cross beam 212 of the upper layer beam at the beginning. After the battery 23 is placed completely in the battery placement space of the lower battery frame 22, install the middle cross beam 212 on the upper layer beam. Then, place another layer of battery 23 on the upper layer beam, that is, set another layer of battery 23 on the upper surface of the lower battery frame 22, and there are two layers of battery 23 set on the lower battery frame 22.

[0046] The upper layer beam and the lower layer beam are connected by a number of connecting beams 213. The connecting beams 213 are arranged on the longitudinal beams 211, that is, both ends of the connecting beam 213 are connected to the longitudinal beams 211. The connecting beam 213 is vertically arranged with the longitudinal beam 211 and the connecting beam 213 extends along the height direction. Arranging the connecting beam 213 can not only be used for connection, but also ensure the strength of the lower battery frame 22. The number of connecting beams 213 arranged on each longitudinal beam 211 is not limited, as long as the connection and strength are ensured. In this solution, four connecting beams 213 are arranged on each longitudinal beam 211. The length of the connecting beam 213 is greater than or equal to the height of the battery 23 to ensure the placement of the battery 23.

[0047] To ensure the strength of the lower battery frame 22, a number of strengthening beams are also arranged on the lower battery frame 22. The arrangement of the strengthening beams does not affect the placement of the battery 23. At the same time, since the bearing capacity of the lower battery frame 22 for the battery 23 is greater than that of the upper battery frame 21, the strength of the cross beam 212 of the lower battery frame 22 is preferably greater than the strength of the upper battery frame 21.

[0048] To place the battery 23 in the lower battery frame 22, a battery 23 placement space is also arranged in the lower battery frame 22. The battery 23 placement space of the lower battery frame 22 is arranged in the same way as that of the upper battery frame 21, which will not be elaborated here.

[0049] A water and electricity connection module is arranged at the front end of the lower battery frame 22. The water and electricity connection module is hidden inside the vehicle frame 1 and can adapt to the shape of the vehicle frame 1, thus saving space.

[0050] To ensure the quick alignment of the upper battery frame 21 and the lower battery frame 22 and the precise connection therebetween, positioning holes 52 are provided on the upper battery frame 21. At least two positioning holes 52 are provided. A positioning pin 51 is provided on the lower battery frame 22. The positioning pin 51 is arranged opposite to the positioning hole 52. When the positioning pin 51 is inserted into the positioning hole 52, the upper battery frame 21 and the lower battery frame 22 are aligned. In this solution, four positioning holes 52 are provided, and the four positioning holes 52 are respectively arranged at the four corners of the upper battery frame 21. Four positioning pins 51 are also provided and are arranged in cooperation with the positioning holes 52.

[0051] To ensure the quick and accurate connection of the upper battery frame 21 and the lower battery frame 22, a quick connection structure is provided. The quick connection structure includes a quick connection seat 41 provided on the upper battery frame 21 and a quick connection plug 42 provided on the lower battery frame 22. The quick connection seat 41 is arranged on one side of the upper battery frame 21 close to the lower battery frame 22. The quick connection plug 42 is arranged corresponding to the quick connection seat 41. When the quick connection plug is inserted into the quick connection seat 41, it indicates that the docking of the upper battery frame 21 and the lower battery frame 22 is completed. After the quick connection seat 41 and the quick connection plug are connected, the connection of the upper battery frame 21 and the lower battery frame 22 is completed. Since the battery box mounting bracket equipped with the battery 23 has a large mass, to ensure the reliable connection of the upper and lower battery frames, multiple quick connection structures are provided. In this solution, twelve quick connection structures are provided. The quick connection structures are arranged on the longitudinal beams 211, and three quick connection structures are arranged on each longitudinal beam 211. At the same time, the quick connection structure can also realize the quick separation and connection of the upper battery frame 21 and the lower battery frame 22 during battery maintenance, reducing the cumbersome steps during battery 23 maintenance.

[0052] When the battery on the vehicle needs to be removed, the vehicle drives into the battery swapping platform. However, in most cases, the vehicle cannot park in the specified position, and the battery swapping cart needs to find the position of the battery. To better identify the precise position of the battery box mounting bracket, feature grooves are provided on the two outer sides of the battery box mounting bracket parallel to the girder. The feature grooves are consistent with the vehicle's forward direction and are used for external reference, while also identifying the precise position of the battery box mounting bracket. The longitudinal beams 211 on both sides of the upper girder are arranged towards the side closer to the middle beam 215 and are connected to the cross beam 212 of the upper girder. The part of the cross beam 212 away from the middle beam 215 and the longitudinal beam 211 enclose to form a feature groove. To ensure the reliable connection of the longitudinal beam 211, a reinforcing beam is provided between the cross beam 212 and the longitudinal beam 211 for connection.

[0053] During the vehicle's driving process, a large amount of foreign matter such as sediment and cinder will enter. Therefore, a sealing plate is provided on the outer side after the upper battery frame 21 and the lower battery frame 22 are connected to protect the battery 23.

[0054] The specific connection method between the upper and lower battery frames and the vehicle girder 1 is as follows:

[0055] Batteries 23 are respectively placed in the three battery placement spaces of the lower battery frame 22. After the batteries 23 are placed, the middle cross beam 212 is installed on the lower battery frame 22. Then, another layer of battery 23 is provided on the upper surface of the lower battery frame 22. The upper battery frame 21 and the lower battery frame 22 are quickly positioned through the positioning pins 51 and the positioning holes 52, and a quick connection structure is used to achieve quick docking. At this time, the three batteries 23 located on the lower battery frame 22 are within the battery placement space of the upper battery frame 21. After the upper and lower battery frames are connected, the upper battery frame 21 is connected to the connection frame to achieve connection with the vehicle.

[0056] In summary, in this solution, the upper battery frame 21 and the lower battery frame 22 are formed by connecting a number of cross beams 212, a number of longitudinal beams 211, and a number of connecting beams 213. The structure is simple and the operation is convenient. The setting of the upper battery frame 21 and the lower battery frame 22 can realize the setting of multiple batteries 23. Currently, the battery placement is mostly in one layer, and this solution can realize the placement of two layers of batteries, which can place more batteries 23 compared with other structures, and at the same time, it is hidden at the vehicle girder 1, saving space. The setting of the positioning pins 51 and the positioning holes 52 can realize the quick positioning of the upper battery frame 21 and the lower battery frame 22, and the setting of the quick connection structure can realize the quick connection of the batteries 23, completing the disassembly and assembly of the battery more quickly and conveniently than the prior art.
