The embodiments of the present utility model will be described in detail below with reference to the drawings.

[0030] It should be understood that the accompanying drawings are only used for exemplary illustration of this application.

[0031] Now, the present utility model will be further described in detail with reference to the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, only illustrating 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 Figures 1 - 9 shown, is arranged on a large truck for placing the battery 23, and at the same time is convenient for 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 is connected to the upper battery frame 21. At the same time, 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, stiffeners are arranged on the two girders 1. The stiffeners connect the two girders 1, which can reinforce the girders 1 and ensure sufficient strength after the battery box mounting bracket is arranged on the girders 1.

[0034] A connection frame is arranged on the vehicle girder 1 to facilitate the connection between the upper battery frame 21 and the vehicle girder 1. The connection frame is connected to the vehicle and the girder 1. The connection frame includes several frame connection beams arranged on the girder 1 and is connected to the upper battery frame 21 through the frame connection beams.

[0035] Several longitudinal beams 211, several cross beams 212 and several connection beams 213 are connected to form the upper battery frame 21. The several 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 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 arranged, 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] A plurality of the cross beams 212 are arranged at intervals, and each cross beam 212 is connected to each longitudinal beam 211. Of course, it can also be arranged that each cross beam is connected to two adjacent longitudinal beams 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 extending 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 between the first longitudinal beam and the second longitudinal beam and connected thereto, four parallel and spaced cross beams are arranged between the second longitudinal beam and the third longitudinal beam and connected thereto, and four parallel and spaced cross beams are arranged between the third longitudinal beam and the fourth longitudinal beam and connected thereto.

[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 arranged in the middle of the longitudinal beams 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 batteries 23 arranged on the lower battery frame can enter the upper battery frame 21. That is, a plurality of cross beams 212 are connected and arranged on the longitudinal beams 211 of the upper layer beam, and the plurality of cross beams 212 are evenly arranged along the extending direction of the longitudinal beams 211. On the longitudinal beams 211 of the lower layer beam, cross beams 212 are only arranged and connected at both ends of the longitudinal beams 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 beams 211. That is, both ends of the connecting beams 213 are connected to the longitudinal beams 211. The connecting beams 213 are perpendicular to the longitudinal beams 211, and the connecting beams 213 extend in the height direction. Arranging the connecting beams 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 beams 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 three successively arranged first battery placement spaces, second battery placement spaces, and third battery placement spaces. The vehicle beam 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 the first battery placement space and the second battery placement space. An intermediate beam 215 is arranged on the upper battery frame 21. The intermediate beam 215 spans across the vehicle beam 1 and connects the first battery placement space and the second battery placement space to form the third battery placement space. The third battery placement space is located between the first battery placement space and the second placement space. The vehicle beam 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 number of reinforcing beams are also arranged on the upper battery frame 21. The arrangement of the reinforcing beams does not affect the placement of the battery 23.

[0041] To place the battery 23, a battery placement space is arranged on the upper battery frame 21. The battery placement space is formed by enclosing a longitudinal beam 211, a cross beam 212, and a connecting beam 213. At least one battery placement space is arranged, and the number of the battery placement spaces is preferably set to an odd number. When one battery placement space is arranged, two vehicle beams 1 are arranged. The battery 23 is located in the middle of the beam 1, so that it is hidden in the beam 1. The battery 23 can be placed according to the shape of the beam 1, and more batteries 23 can be arranged. At the same time, the occupied volume of the battery mounting bracket is reduced. When three battery placement spaces are arranged, the middle one is the second placement space. The first placement space and the third placement space are located on both sides of the second placement space. After the upper battery frame 21 is connected to the beam 1, the beam 1 passes through the second placement space and is connected to the upper battery frame 21. At this time, the battery located in the second placement space is simultaneously located between the two beams 1. The first placement space and the third placement space are located on both sides of the beam 1 to ensure balance. The battery placement space 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 arranged in each battery placement space.

[0042] The length direction of the battery placement space is the same as the extension direction of the beam 1. The placement of the battery 23 is adapted to the beam 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 plurality of cross beams 212 and a plurality of longitudinal beams 211. That is, a plurality of cross beams 212, a plurality of longitudinal beams 211, and a plurality 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 plurality 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 be unequal, 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, 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 plurality 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 extending 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, which is convenient for placing the battery 23. After the battery 23 is placed completely, the middle cross beam 212 is then connected to 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 that the middle cross beam 212 of the upper layer beam is not provided at the beginning. After the battery 23 is placed completely in the battery placement space of the lower battery frame 22, the middle cross beam 212 on the upper layer beam is installed. Then, another layer of the battery 23 is placed on the upper layer beam, that is, another layer of the battery 23 is provided on the upper surface of the lower battery frame 22, and two layers of the battery 23 are provided on the lower battery frame 22.

[0046] The upper beam and the lower 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 perpendicular to the longitudinal beam 211 and the connecting beam 213 extends in the height direction. The setting of 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 reinforcing beams are also arranged on the lower battery frame 22. The setting of the reinforcing 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 that 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 connector module is arranged at the front end of the lower battery frame 22. The water and electricity connector module is hidden in the vehicle girder 1 and adapts to the shape of the vehicle girder 1, which can save space.

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

[0051] To ensure the quick and accurate connection between 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 socket 41 provided on the upper battery frame 21 and a quick-connection plug 42 provided on the lower battery frame 22. The quick-connection socket 41 is provided on the side of the upper battery frame 21 close to the lower battery frame 22, and the quick-connection plug 42 is arranged corresponding to the quick-connection socket 41. When the quick-connection plug is inserted into the quick-connection socket 41, it indicates that the docking of the upper battery frame 21 and the lower battery frame 22 is completed. After the quick-connection socket 41 and the quick-connection plug are connected, the connection between the upper battery frame 21 and the lower battery frame 22 is completed. Since the battery box mounting bracket with the battery 23 installed has a relatively large mass, to ensure the reliable connection between the upper and lower battery frames, multiple quick-connection structures are provided. In this solution, twelve quick-connection structures are provided, and the quick-connection structures are arranged on the longitudinal beams 211, with three arranged on each longitudinal beam 211. At the same time, the quick-connection structure can also achieve the quick separation and connection between 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 trolley needs to find the position of the battery. To better identify the precise position of the battery box mounting bracket, characteristic grooves are provided on the two outer sides of the battery box mounting bracket parallel to the girder. The characteristic grooves are consistent with the vehicle's forward direction and are used for external reference to identify the precise position of the battery box mounting bracket at the same time. The longitudinal beams 211 on both sides of the upper layer beam are arranged towards the side close to the middle beam 215 and are connected to the cross beam 212 of the upper layer beam. The part of the cross beam 212 away from the middle beam 215 and the longitudinal beam 211 enclose to form a characteristic 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] Since a large amount of foreign matter such as sediment and coal cinder will enter during the vehicle's driving, 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 described below:

[0055] Place the batteries 23 in the three battery placement spaces of the lower battery frame 22 respectively. After the placement of the batteries 23 is completed, install the middle cross beam 212 on the lower battery frame 22. Then, set another layer of batteries 23 on the upper surface of the lower battery frame 22. Position the upper battery frame 21 and the lower battery frame 22 quickly through the positioning pins 51 and the positioning holes 52, and achieve quick docking through the quick connection structure. At this time, the three batteries 23 on the lower battery frame 22 are located in the battery placement spaces of the upper battery frame 21. After the upper and lower battery frames are connected, connect the upper battery frame 21 with 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 several cross beams 212, several longitudinal beams 211, and several 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, most battery placements are 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. 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 batteries more quickly and conveniently than the prior art.
