[0023] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] The following is a reference to the appendix. Figures 1 to 6 This invention provides a detailed description of the integrated battery pack cover 100, the battery pack, and the vehicle 1000 according to embodiments of the present invention.

[0025] like Figure 1 As shown, the vehicle 1000 of this embodiment includes a vehicle body and a battery pack. The vehicle body has a pedal beam 200.

[0026] The battery pack of this utility model embodiment includes an integrated battery pack cover 100.

[0027] like Figure 1 and Figure 2 As shown, the integrated battery pack cover 100 of this embodiment includes a cover body 1 and a seat crossbeam 2. The cover body 1 has a thickness direction (e.g., Figure 1 The seat beam 2 is integrated on the support surface 11 on one side of the seat beam (in the vertical direction). The seat beam 2 is provided with a first mounting hole 21 for connecting with the seat (not shown in the figure). Both ends of the seat beam 2 in its extension direction are connected to the pedal beam 200 of the vehicle body.

[0028] Specifically, the seat is provided with a third mounting hole. When connecting the seat and the seat crossbeam 2, fasteners are used to pass through the first mounting hole 21 and the third mounting hole to fix the seat and the seat crossbeam 2.

[0029] In this embodiment of the invention, the top cover 1 and the seat crossbeam 2 are integrated into one unit. When the battery pack is installed on the vehicle body, the integrated battery pack top cover 100 is connected to the vehicle body's pedal beam 200 via the seat crossbeam 2. When the battery pack needs to be removed from the vehicle body for maintenance, the seat crossbeam 2 can be removed from the pedal beam 200 to detach the battery pack from the vehicle body. At this time, the seat is located on the integrated battery pack top cover 100, and there is no need to remove the connection between the seat and the integrated battery pack top cover 100 (or the seat crossbeam 2). If the internal parts of the battery pack need to be repaired, the integrated battery pack top cover 100 can be removed from the battery pack housing to expose the internal parts of the battery pack without removing the seat from the seat crossbeam 2 and then removing the seat crossbeam 2 and the battery pack. After the battery pack maintenance is completed, the battery pack is assembled, and then the seat crossbeam 2 is connected to the vehicle body's pedal beam 200. When reinstalling the battery pack, there is no need to reconnect the integrated battery pack top cover 100 (or the seat crossbeam 2) and the seat.

[0030] Therefore, the integrated battery pack cover 100 of this utility model integrates the cover body 1 and the seat crossbeam 2 into one unit, which can improve the installation and disassembly efficiency of the battery pack and the vehicle body, reduce the maintenance difficulty of the battery pack, improve maintenance efficiency, and thus reduce maintenance costs.

[0031] Specifically, in Figures 1 to 6 In the embodiment shown, the thickness direction of the upper cover body 1 is the same as the vertical direction, and the extension direction of the seat beam 2 is the same as the horizontal direction.

[0032] In some embodiments, refer to Figure 2 , the seat cross member 2 comprises a mounting beam 22 and a first reinforcing beam 23, one side (lower side) of the mounting beam 22 is connected to one side (lower side) of the first reinforcing beam 23 and both are connected to the support surface 11, the other side (upper side) of the mounting beam 22 is provided with a first mounting hole 21, both ends of the mounting beam 22 in the extension direction thereof and both ends of the first reinforcing beam 23 in the extension direction thereof are configured to be connected to the pedal beam 200. That is, the seat cross member 2 mounts a seat through the mounting beam 22, and is connected to the vehicle body through the mounting beam 22 and the first reinforcing beam 23, which not only improves the strength of the seat cross member 2 itself, but also increases the contact area between the seat cross member 2 and the support surface 11 and the contact area between the seat cross member 2 and the vehicle body, thereby improving the connection strength between the seat cross member 2 and the vehicle body, further improving the connection strength between the integrated battery pack upper cover 100 and the vehicle body, and improving the connection strength between the battery pack and the vehicle body.

[0033] Specifically, refer to Figure 2 , the mounting beam 22 and the first reinforcing beam 23 are both "Ω"-shaped beams.

[0034] In some embodiments, the seat cross member 2 further comprises a first fixing nut (not shown in the figures), the first fixing nut is located between the mounting beam 22 and the support surface 11, and the first fixing nut is provided on the mounting beam 22 and opposite to the first mounting hole 21 for connecting with the seat. When mounting the seat and the seat cross member 2, a fastening bolt is passed through the third mounting hole on the seat and the first mounting hole 21 and then fitted into the first fixing nut, so as to realize the bolted connection between the seat and the seat cross member 2.

[0035] The first fixing nut is located between the mounting beam 22 and the support surface 11, that is, the first fixing nut is located on the lower side of the mounting beam 22 and in the space formed between the mounting beam 22 and the support surface 11, and is not exposed to the outside. The mounting beam 22 and the upper cover body 1 provide protection for the first fixing nut, so that during transportation and installation of the integrated battery pack upper cover 100 of the embodiment of the present utility model, there is no need to protect the first fixing nut, thereby reducing the difficulty and cost of transportation and installation of the integrated battery pack upper cover 100 of the embodiment of the present utility model, further improving the efficiency of installation and disassembly of the battery pack and the vehicle body, reducing the maintenance difficulty and maintenance cost of the battery pack, and facilitating further improvement of maintenance efficiency.

[0036] Further, the mounting beam 22 and the first reinforcing beam 23 are integrally formed, so as to ensure the integrity and connection strength of the mounting beam 22 and the first reinforcing beam 23.

[0037] Specifically, the mounting beam 22 and the first reinforcing beam 23 are sheet metal structures, that is, they are stamped and formed from metal plates.

[0038] Furthermore, the seat crossbeam 2 is bonded, welded, riveted, and / or screwed to the support surface 11. That is, each of the mounting beam 22 and the first reinforcing beam 23 is bonded, welded, riveted, and / or screwed to the support surface 11. The seat crossbeam 2 and the support surface 11 have multiple connection methods, and one or more of them can be selected for connection to ensure the connection strength between the seat crossbeam 2 and the support surface 11.

[0039] In some embodiments, the seat crossbeam 2 further includes a second fixing nut (not shown in the figure). The mounting beam 22 and the first reinforcing beam 23 are provided with second mounting holes 24 and second fixing nuts at both ends of their extension direction. The second fixing nut on the mounting beam 22 is located between the mounting beam 22 and the support surface 11. The second fixing nut on the first reinforcing beam 23 is located between the first reinforcing beam 23 and the support surface 11. The second fixing nut is opposite to the second mounting hole 24 to connect with the pedal beam 200.

[0040] Specifically, such as Figure 3 As shown, the pedal beam 200 includes a body 2001 and a connector 2002. One end of the connector 2002 is fixed to the body 2001, and the other end of the connector 2002 is provided with a fourth mounting hole 20021. When installing the seat crossbeam 2, the fourth mounting hole 20021 and the second mounting hole 24 are aligned, and a bolt is used to pass through the fourth mounting hole 20021 and the second mounting hole 24 and then fitted into the second fixing nut to realize the connection between the seat crossbeam 2 and the pedal beam 200.

[0041] The second fixing nut is located in the space between the mounting beam 22 (or the first reinforcing beam 23) and the supporting surface 11, and is not exposed. Therefore, during the transportation and installation of the integrated battery pack cover 100 of this utility model embodiment, there is no need to protect the second fixing nut, thereby reducing the difficulty and cost of transportation and installation of the integrated battery pack cover 100 of this utility model embodiment. This further improves the efficiency of battery pack installation and disassembly, reduces the difficulty and cost of battery pack maintenance, and helps to further improve maintenance efficiency.

[0042] For details, please refer to Figure 3 The height of the first reinforcing beam 23 in the vertical direction is less than the height of the mounting beam 22 in the vertical direction.

[0043] In some embodiments, such as Figure 1 and Figure 4As shown, the integrated battery pack cover 100 further includes a reinforcing beam 3, which is disposed on the support surface 11. Both ends of the reinforcing beam 3 in its extending direction are used to approach or abut against the pedal beam 200. The reinforcing beam 3 can increase the strength of the integrated battery pack cover 100. At the same time, since both ends of the reinforcing beam 3 are close to or abut against the pedal beam 200, when the pedal beam 200 is impacted, a portion of the force can be transmitted to the cover body 1 through the contact between the pedal beam 200 and the reinforcing beam 3, thereby absorbing a portion of the load borne by the pedal beam 200 and improving the reliability and stability of the connection between the integrated battery pack cover 100 and the pedal beam 200, that is, improving the reliability and stability of the connection between the battery pack and the vehicle body.

[0044] In some embodiments, such as Figure 4 As shown, the reinforcing beam 3 includes a second reinforcing beam 31 and a collision beam 32. The second reinforcing beam 31 is disposed on the support surface 11. Both ends of the second reinforcing beam 31 in its extension direction are provided with collision beams 32. One end of the collision beam 32 in the extension direction of the second reinforcing beam 31 is fastened to the second reinforcing beam 31, and the other end of the collision beam 32 in the extension direction of the second reinforcing beam 31 forms a cavity with the second reinforcing beam 31 and is used to be adjacent to or abut against the pedal beam 200. Thus, the other end of the collision beam 32 is in contact with the second reinforcing beam 31, and the other end of the collision beam 32 is higher than the first end and forms a cavity with the second reinforcing beam 31. In other words, the surface area of ​​the other end of the collision beam 32 is larger than the surface area of ​​the first end, thereby increasing the contact area between the reinforcing beam 3 and the pedal beam 200 through the other end of the collision beam 32, and further improving the strength of the reinforcing beam 3 itself, thereby improving the reliability and stability of the connection between the integrated battery pack cover 100 and the pedal beam 200, that is, improving the reliability and stability of the connection between the battery pack and the vehicle body.

[0045] In some embodiments, such as Figure 5 As shown, the reinforcing beam 3 further includes a reinforcing plate 33, which is disposed within the cavity. The reinforcing plate 33 includes a plate portion 331 and multiple connecting portions (not shown in the figure). The edge of the plate portion 331 is provided with multiple connecting portions. The multiple connecting portions of the reinforcing plate 33 correspond one-to-one with and are connected to the adjacent second reinforcing beam 31 and collision beam 32. The reinforcing plate 33 is disposed between the other end of the collision beam 32 and the second reinforcing beam 31. The reinforcing plate 33 connects the collision beam 32 and the second reinforcing beam 31 through multiple connecting portions, thereby increasing the connection strength between the other end of the collision beam 32 and the second reinforcing beam 31, and also increasing the strength of the reinforcing beam 3 at the end. This further improves the reliability and stability of the connection between the integrated battery pack cover 100 and the pedal beam 200, that is, further improves the reliability and stability of the connection between the battery pack and the vehicle body.

[0046] For details, please refer to Figure 4 and Figure 5 Both the collision beam 32 and the second reinforcing beam 31 are "U" shaped beams. The plate part 331 of the reinforcing plate 33 is a quadrilateral plate structure. Each of the four edges of the plate part 331 is provided with a connecting part. The connecting parts on the front, rear and upper sides of the plate part 331 are opposite to and connected to the collision beam 32. The connecting part on the lower side of the plate part 331 is connected to the second reinforcing beam 31.

[0047] The second reinforcing beam 31 is bonded, welded, riveted, and / or screwed to the supporting surface 11. The second reinforcing beam 31 and the supporting surface 11 can be connected in various ways, and one or more combinations can be selected to ensure the connection strength between the second reinforcing beam 31 and the supporting surface 11. The collision beam 32 is bonded, welded, riveted, and / or screwed to the second reinforcing beam 31. The second reinforcing beam 31 and the collision beam 32 can be connected in various ways, and one or more combinations can be selected to ensure the connection strength between the second reinforcing beam 31 and the collision beam 32.

[0048] Specifically, the reinforcing beam 3 has two second reinforcing beams 31, and the lower sides of the two second reinforcing beams 31 are connected, thereby further improving the strength of the reinforcing beam 3 and further improving the reliability and stability of the connection between the integrated battery pack cover 100 and the pedal beam 200, that is, improving the reliability and stability of the connection between the battery pack and the vehicle body.

[0049] In some embodiments, such as Figure 1 and Figure 6 As shown, the upper cover body 1 includes a body portion 12, a protrusion 13, and an electrical compartment cover 14. The body portion 12 has a support surface 11. The protrusion 13 is connected to the body portion 12 and protrudes to one side of the upper cover body 1 to form the electrical compartment of the battery pack. The electrical compartment cover 14 is provided on the protrusion 13. The body portion 12 and the protrusion 13 are integral structures. The upper cover body 1 forms the protrusion 13 by stamping. The protrusion 13 forms a closed area on all sides, providing an installation and protection area for the electrical components inside the battery pack.

[0050] Furthermore, the upper cover body 1 further includes a sealing ring (not shown in the figure), which is located between the electrical compartment cover 14 and the protrusion 13 to achieve sealing of the electrical compartment.

[0051] The electrical compartment cover 14 does not have an integrated seat crossbeam and does not have rear seats.

[0052] Specifically, the main body 12, the protrusion 13, and the electrical compartment cover 14 are all made of steel or aluminum.

[0053] Therefore, the battery pack of this utility model embodiment has high installation and disassembly efficiency with the vehicle body, low maintenance difficulty, and is conducive to improving maintenance efficiency and reducing maintenance costs.
