Referring to fig. 1 and 7, the present embodiment provides a battery pack 100, including a case 110, a cover 120, a first buffer structure 130, and a second buffer structure 150, wherein a mounting portion 111 is disposed on the case 110; the cover 120 is connected to the case 110, and the cover 120 is provided with a plug member 121; the first buffer structure 130 is arranged on the mounting part 111; the second buffer structure 150 is disposed on the plug 121. Due to the arrangement of the first buffer structure 130 and the second buffer structure 150, the battery pack 100 has a good shock absorption and buffering effect after being mounted on a frame, stable and reliable connection is ensured, the shock resistance is better, and stable operation of the battery pack 100 is facilitated. It can be understood that the first buffer structure 130 and the second buffer structure 150 are respectively disposed on the case 110 and the cover 120, so as to absorb impact energy at different positions and in different directions, and have better impact resistance and better shock absorption and buffering effects.

In this embodiment, the mounting portion 111 includes a cross beam 113, the cross beam 113 is protruded from a sidewall of the box 110, and the cross beam 113 is provided with a first mounting hole 114. The cross member 113 is used to connect the case 110 with the vehicle. Alternatively, the cross beam 113 is protruded on two opposite sidewalls of the case 110. The box body 110 is rectangular, and the cross beam 113 may be disposed on two side walls in the length direction, or two side walls in the width direction, or the cross beam 113 is disposed on four side walls of the box body 110 at the same time, which is not limited herein. In this embodiment, the beams 113 are disposed on two side walls of the box body 110 in two length directions, two first mounting holes 114 are disposed on each beam 113, and the first mounting holes 114 on the two beams 113 are symmetrically disposed, so that the box body 110 is more uniformly stressed when being mounted on a frame. Of course, the number and distribution of the first mounting holes 114 can be flexibly adjusted, and are not limited to the above-mentioned example. For example, the number of the first mounting holes 114 on each cross member 113 is one, three, four, or more.

Referring to fig. 2 and 3, the first buffer structure 130 includes a connection member 131 and an elastic member 135; the connecting piece 131 is arranged in the first mounting hole 114, one end of the elastic piece 135 is connected with the cross beam 113, and the other end is connected with the connecting piece 131; the connecting member 131 is used to connect with a vehicle frame. Optionally, the connecting member 131 is provided with a second mounting hole 133 coaxial with the first mounting hole 114, and the second mounting hole 133 is used for a fastener 137 to pass through so as to connect with the frame. It should be appreciated that the fasteners 137 may be bolts or the like that pass through the connection points on the frame and the connecting members 131 in the cross member 113 in turn to securely fasten the battery pack 100 to the frame.

Optionally, at least one side of the connecting member 131 is provided with one or more elastic members 135; if the connecting member 131 has a plurality of elastic members 135 on the same side, the elastic members 135 are uniformly spaced. Optionally, one or more elastic members 135 are respectively disposed at two sides of the connecting member 131, and the elastic member 135 at one side is symmetrically disposed with the elastic member 135 at the other side. Of course, without limitation, in other alternative embodiments, the elastic members 135 may be arranged in an asymmetric design, and the number of the elastic members 135 on one side of the connecting member 131 may be the same as or different from that of the elastic members 135 on the other side, and is not limited herein.

In this embodiment, the elastic element 135 can be, but is not limited to, a spring plate, an elastic rubber pad, or the like.

With reference to fig. 2, a first structural form of the first buffer structure 130 is as follows: the upper and lower sides of the connecting member 131 are respectively provided with a spring, the inner diameter of the spring is larger than the diameter of the second mounting hole 133, and the axis of the spring and the axis of the second mounting hole 133 are positioned on the same line. One end of the spring is fixedly connected to the surface of the connecting member 131, and the other end is fixedly connected to the cross beam 113. The axes of the springs on the two sides are all positioned on the same straight line. It will be appreciated that the fastener 137 passes through the second mounting hole 133 to be fixedly connected to a connection point (such as a lifting lug) on the frame. For example, one end of the fastener 137 passes through the second mounting hole 133 and abuts against the connecting member 131, and the other end is fastened to the lifting lug by a bolt or a nut. If the impact force applied to the battery pack 100 is too large, the battery pack 100 can move up and down along the axial direction of the spring (i.e., the axial direction of the second mounting hole 133 or the axial direction of the fastening member 137) to perform shock absorption and buffering, so as to achieve a buffering effect, improve the impact resistance, and effectively reduce the damage of the impact force to the battery pack 100.

It should be noted that, after the fastener 137 fixes the battery pack 100 and the frame, the resilience forces of the springs at both sides at this time are respectively set to be F2, and the axial force when the fastener 137 is tightened is set to be F1, where F1 is smaller than F2. Namely, the spring is not completely compacted in the initial state after installation, and a buffer allowance is left. When the battery pack 100 is subjected to large impact force F3, F3 is larger than F2, the battery pack 100 can generate upward or downward deviation in the state, and the spring has compression allowance for buffering, so that the battery pack has a good damping and buffering effect and good impact resistance, has a good digestion and absorption effect on the impact force, and reduces the risk of damage to the battery pack 100 in collision.

For example, two, three, four, five or more springs are provided at the upper side of the connection member 131. Two, three, four, five or more springs are provided at the lower side of the connection member 131. The plurality of springs of each side are disposed at the outer circumference of the second mounting hole 133 at regular intervals. Alternatively, the plurality of springs may be arranged in a ring shape in a square, rectangular, circular, or the like shape. In this embodiment, two springs are respectively disposed on the upper side and the lower side, and the two springs on the same side are symmetrically disposed about the second mounting hole 133. The four springs on both sides are symmetrically distributed about the connecting member 131. One end of each spring is fixedly connected with the connecting piece 131, and the other end is fixedly connected with the cross beam 113. It is understood that the fixed connection includes, but is not limited to, welding, adhesive bonding, bolting or snapping, etc. The springs on the same side or different sides are symmetrically distributed, so that the stress is more uniform, and the damping and buffering effects are improved.
