The clearance recess 12 extends through the housing 10 along a first preset direction, and the opening of the clearance recess 12 is oriented toward a second preset direction. The first preset direction and the second preset direction are perpendicular to each other. A hanger 80 is used to connect to the beam 8, and the battery 1 is connected to the hanger 80.

[0035] The battery mounting structure of this utility model includes a battery 1 and a hanger 80. The housing 10 of the battery 1 has a relief recess 12, which can avoid the vehicle's main beam 8, making it easy to install the battery and making full use of the vehicle body space. Furthermore, the battery 1 is fixedly connected to the main beam 8 through the hanger 80. This installation method can improve the overall connection rigidity between the battery and the vehicle, while reducing the vehicle body weight and manufacturing costs.

[0036] In practice, the main beam 8 is simply inserted into the relief recess 12 and is not connected to the relief recess 12.

[0037] Specifically, the battery mounting structure also includes a first connector 81, through which the hanger 80 is fixedly connected to the main beam 8. The first connector 81 is located outside the clearance recess 12. This arrangement achieves a fixed connection between the hanger 80 and the main beam 8, and the location of the first connector 81 outside the clearance recess 12 provides more installation space, facilitating installation.

[0038] Specifically, the battery mounting structure also includes a second connector 82, through which the housing 10 is fixedly connected to the hanger 80. This arrangement achieves a fixed connection between the housing 10 and the hanger 80.

[0039] Specifically, the first connecting component 81 is a bolt, the hanger 80 has a first fastening hole, and the main beam 8 has a second fastening hole.

[0042] Specifically, the housing 10 also has receiving protrusions 11 for accommodating the battery cell 20, and receiving protrusions 11 are provided on both sides of the recess 12 along a third preset direction; wherein, the first preset direction, the second preset direction, and the third preset direction are arranged perpendicularly to each other; the hanger 80 and the main beam 8 form a receiving area 83, and the receiving area 83 includes a plurality of receiving spaces 831 arranged sequentially along the third preset direction, and the plurality of receiving spaces 831 are arranged one-to-one with the plurality of receiving protrusions 11 of the battery 1, with each receiving protrusion 11 inserted into the corresponding receiving space 831. This arrangement allows the receiving protrusions 11 to be arranged in the receiving spaces 831, making full use of the vehicle body space.

[0043] In specific implementation, since both sides of the avoidance recess 12 have accommodating protrusions 11 in the third preset direction, each accommodating protrusion 11 can accommodate a battery cell, so that the space of the housing 10 is fully utilized, more battery cells can be accommodated in a unit volume, improving space utilization and thus improving the energy density of the battery.

[0044] It should be noted that the first preset direction is the width direction of battery 1, the second preset direction is the height direction of battery 1, and the third preset direction is the length direction of battery 1.

[0045] Specifically, the battery mounting structure includes multiple batteries 1 arranged sequentially along a first preset direction; a hanger 80 and a main beam 8 enclose multiple receiving areas 83 arranged sequentially along the first preset direction, with each battery 1 corresponding to one of the multiple receiving areas 83, and the receiving protrusion 11 of each battery 1 inserted into the receiving space 831 of the corresponding receiving area 83. This arrangement realizes the installation and arrangement of multiple batteries 1.

The multiple connecting beams 843 are spaced-apart between the two main beams 8 to form multiple receiving spaces 831 arranged sequentially along the first preset direction. One end of each connecting beam 843 is connected to one of the two main beams 8 through the first connector 81, and the other end of each connecting beam 843 is connected to the other of the two main beams 8 through the first connector 81.

[0047] In practice, the connection position of the connecting beam 843 is not within the range of the avoidance recess 12. This setting provides more installation space and facilitates installation.

[0048] Specifically, the housing 10 is provided with at least two battery layers 30 stacked along a second preset direction. Each battery layer 30 includes a battery cell 20, and the at least two battery layers 30 include a first battery layer 31.

[0049] In practice, each of the avoidance recesses 12 is used to avoid the main beam, which meets the actual use requirements; the first battery layer 31 is arranged in a hollow manner, which increases the space utilization of the battery; and the arrangement of at least two battery layers 30 improves the energy density of the battery.

[0050] Specifically, at least two battery layers 30 include a second battery layer 32 disposed within the housing 13. The second battery layer 32 includes at least two battery cells 20, which are sequentially disposed within the housing 13 along a third preset direction.

[0051] Optionally, the battery includes two battery layers 30, namely a first battery layer 31 and a second battery layer 32.

[0052] Specifically, the housing 10 further includes at least one reinforcing plate, which is disposed within and fixedly connected to the housing 13 to divide the housing 13 into at least two cavities for accommodating the battery cells 20. In practice, the reinforcing plate can increase the overall strength of the housing 10. The reinforcing plate is welded to the housing 10.

[0053] Optionally, the housing 10 includes a reinforcing plate to divide the housing 13 into two cavities, each of which houses a battery cell 20.

[0054] Specifically, the tops of the multiple receiving protrusions 11 are aligned flush with each other in a second predetermined direction. This arrangement makes the multiple receiving protrusions 11 have the same structure, and each of the multiple receiving protrusions 11 can accommodate a single battery cell, thereby improving space utilization and thus increasing the energy density of the battery.

[0055] This utility model also provides a vehicle, including a battery mounting structure and a main beam 8, wherein the battery mounting structure is the battery mounting structure described above.

[0056] This utility model's battery mounting structure fully utilizes vehicle body space, improves the overall connection rigidity between the battery and the vehicle body, and simultaneously reduces vehicle weight and manufacturing costs. The battery mounting structure connects the hanger to the vehicle's main beam, and the bottom-mounted battery is then bolted to the hanger. The accommodating protrusion 11 is inserted into the space between the main beam and the hanger, effectively addressing the shortcomings of traditional mounting methods: firstly, the battery fails to fully utilize the space between the longitudinal beams, resulting in limited placement space; secondly, the lack of connection between the battery and the vehicle floor leads to poor overall connection rigidity, posing safety hazards in collisions; and thirdly, to meet battery installation requirements, additional structures such as brackets and crossbeams are needed, increasing vehicle weight and manufacturing costs.

[0057] Specifically, the battery mounting structure of this invention reduces the number of batteries 1 to 2-3, significantly decreasing the number of batteries 1 required for vehicle installation. This also brings the following advantages: fewer batteries, fewer wiring harnesses between batteries, fewer water connection channels, easier connection, stronger system stability, and lower costs. Batteries 1 are changed from multiple small-capacity battery cells to a few large-capacity battery cells, reducing the number of battery structural components and other parts, thus lowering PACK assembly costs. The volume utilization rate of the batteries in the overall vehicle layout is improved.

[0058] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0059] The battery mounting structure of this utility model includes a battery 1 and a hanger 80.
