An inspection door is installed on the outside of the battery box cover, and the inspection door and the battery box cover are rotatably connected. The inspection door and the battery box cover are installed by stainless steel piano hinges and stainless steel riveting. When the inspection door is closed, the inspection door and the battery box cover are connected by installing fixing bolts, so that the inspection door can close the battery box cover. When the battery inside the battery box cover needs to be inspected, it is rather troublesome. Therefore, it is particularly important to improve the existing battery box cover and design a new electric bus battery box cover appearance structure to solve the above-mentioned technical defects and improve the practicability of the overall battery box cover.

[0026] The connection assembly 3 is used for limiting the connection between the inspection door 2 and the battery box cover body 1 .

[0027] When the battery is in the closed position, the locking nut 5 is engaged with the locking nut 5, and the locking nut 5 is engaged with the locking nut 5. When the battery is in the closed position, the locking nut 5 is engaged with the locking nut 5, and the locking nut 5 is engaged with the locking nut 5. When the battery is in the closed position, the locking nut 5 is engaged with the locking nut 5, and the locking nut 5 is engaged with the locking nut 5. When the battery is in the closed position, the locking nut 5 is engaged with the locking nut 5, and the locking nut 5 is engaged with the locking nut 5.

[0028] Among them, a fixing plate 7 is provided inside the battery box cover body 1 and at one end close to the clip 5, and a plurality of clip grooves are provided inside the fixing plate 7. The internal structure size of the clip grooves is designed to correspond to the external structure size of the clip 5. The fixing plate 7 is connected to the clip 5 through the clip grooves, and the clip 5 is connected to the clip grooves, so that the clip 5 can be connected to the fixing plate 7, thereby enabling the clip 5 to be connected to the battery box cover body 1.

[0029] Secondly, a limiting groove 8 is provided inside the fixing plate 7 and the clamping part 5. The internal structure size of the limiting groove 8 is designed to correspond to the external structure size of the limiting rod 6. The fixing plate 7 and the clamping part 5 are connected to the limiting rod 6 through the limiting groove 8. The limiting groove 8 is connected to the limiting rod 6, so that the fixing plate 7 and the clamping part 5 can be connected with the limiting rod 6.

[0030] Furthermore, a limit block 9 is provided on the outside of the limit rod 6 and inside the inspection door 2, and a compression spring 10 is provided on the top of the limit block 9 and on the outside of the limit rod 6. The compression spring 10 is connected to the limit rod 6 through the limit block 9. The compression spring 10 is connected to the limit block 9 so that the compression spring 10 can be connected to the limit rod 6. When the compression spring 10 drives the limit block 9 to move, the limit rod 6 can move, and the limit rod 6 is pulled to move it out of the inner position of the clamping groove. When the clamping member 5 is rotated to the inner position of the clamping groove, the clamping member 5 is released. The limiting rod 6 is displaced by compressing the limiting block 9 with the compression spring 10, so that the limiting rod 6 can be displaced and moved to the inside of the two groups of limiting grooves 8, so that the clamping member 5 can be limitedly connected with the clamping groove, thereby being limitedly connected with the fixing plate 7, and the inspection door 2 is closed. When it is necessary to inspect the battery inside the battery box cover body 1, the above operation is performed in reverse, so that the inspection door 2 can be opened to inspect the battery.

The battery box cover main body 1 is formed as a whole by RTM process, and the surface flatness is better. Foam reinforcing ribs are added to make the strength better. The lightweight design reduces the weight by 20%. The original hand-layup process has a large deformation amount and often causes the risk of deformation and water accumulation during use. The current RTM process has the increase of reinforcing ribs, which is much better than the original process in strength.

[0032] Furthermore, a plurality of groups of sealing strips are provided on the outside of the inspection door 2 and inside the battery box cover body 1, a sealing groove is provided inside the battery box cover body 1 and on the outside of the inspection door 2, and the battery box cover body 1 is connected to the sealing strip through the sealing groove. The sealing strip is installed on the outside of the inspection door 2.

The sealing strip can increase the sealing performance of the connection between the inspection door 2 and the battery box cover body 1 to ensure sealing, and no water can enter during the rain test.

[0033] In this embodiment, the implementation scenario is specifically as follows: when the inspection door 2 is closed, the inspection door 2 and the battery box cover body 1 can be closed through the connecting assembly 3, and the limit rod 6 is pulled to move it out from the inside of the clamping groove. When the clamping member 5 rotates to the inside of the clamping groove, the limit rod 6 is released, and the limit block 9 is displaced by compressing the spring 10, so that the limit rod 6 can be displaced and displaced to the inside of the two groups of limit grooves 8, so that the clamping member 5 can be limitedly connected with the clamping groove, thereby increasing the stability of the connection between the clamping member 5 and the battery box cover body 1, so that the inspection door 2 can be closed. When the battery inside the battery box cover body 1 needs to be repaired, When carrying out maintenance, the above-mentioned operation is performed in reverse so that the maintenance door 2 can be opened for maintenance of the battery. Through the overall design, it is convenient to open the maintenance door 2 for maintenance of the battery. The battery box cover main body 1 is integrally formed by the RTM process, and the surface flatness is better. Foam reinforcement ribs are added to make the strength better. The lightweight design reduces the weight by 20%. The original hand-layup process has a large deformation amount and often causes the risk of deformation and water accumulation during use. The current RTM process has an increase in reinforcement ribs, which is much better than the original process in strength. Compared with the existing box cover shape structure, the utility model can improve the overall practicality of the box cover shape structure through design.
