[0044] The present invention is described below with specific embodiments, but they are not intended to be limiting of the invention.

[0045] Embodiment 1

[0046] like Figure 1-Figure 8 As shown, in this embodiment, a battery compartment is provided, including a compartment body 1, a receiving chamber 101 is arranged inside the compartment body 1, an inner box 102 for receiving a battery module is arranged inside the receiving chamber 101, a gap is left between the outer wall of the inner box 102 and the inner wall of the receiving chamber 101, and a soft filling layer with flame retardant performance can be filled in the gap, and a compartment cover 103 is arranged at the upper end of the compartment body 1; a bearing part 2 is arranged inside the receiving chamber 101, and the bearing part 2 is used to support the inner box 102 placed in the receiving chamber 101; a plurality of The buffer assembly 3 can effectively reduce the vibration and impact of the battery module caused by bumps during the driving of the vehicle, thereby reducing the risk of damage to the battery module and improving the safety of the entire battery compartment. Each buffer assembly 3 includes a fixed block 301, which is fixed to the bottom of the accommodating cavity 101; two cross bars 302 are hinged on both sides of the fixed block 301, and the cross bars 302 can rotate upward or downward on the fixed block 301; an elastic body 303 is provided on the cross bar 302, and two elastic bodies 303 are provided on each cross bar 302;

[0047] Among them, the middle parts of the two elastomers 303 on the same cross bar 302 are slidably connected to the bottom of the accommodating cavity 101, the ends of the two elastomers 303 on the same cross bar 302 close to the fixed block 301 are fixed to the cross bar 302, the ends of the two elastomers 303 on the same cross bar 302 away from the fixed block 301 slide along the axis of the cross bar 302, and the ends of the two elastomers 303 on the same cross bar 302 away from the fixed block 301 are connected to the bottom of the bearing part 2.

[0048] The elastic body 303 is in an arc shape, and the projection of the two elastic bodies 303 of the same crossbar 302 to the bottom of the accommodating cavity 101 is an ellipse.

[0049] The battery module is placed in the inner box 102. At this time, the buffer assembly 3 supports the battery module in the inner box 102. In the initial state, the inner box 102 presses down the bearing part 2 due to the weight of the battery module in the inner box 102, causing the bearing part 2 to exert downward pressure on the buffer assembly 3. At this time, the end of the elastomer 303 away from the fixed block 301 is pressed down by the bearing part 2, and the elastomer 303 is deformed. At the same time, the cross bar 302 rotates downward by a certain angle. When the elastomer 303 is deformed to a certain extent and is sufficient to bear the weight of the battery module in the inner box 102, the initial buffer state of the buffer assembly for the battery module is formed.

[0050] In the above description, the elastic body 303 produces two kinds of deformations, one is that the elastic body 303 gradually deforms toward smoothness, and the other is that the middle parts of the two elastic bodies 303 slide away from each other.

[0051] When the vehicle is running, the buffer component 3 can effectively buffer the battery module;

[0052] The buffering process is as follows: when the vehicle bumps up and down, the inner box 102 will move up and down with the battery module, and this movement will further produce dynamic pressure changes on the load-bearing part 2. The elastic body 303 in the buffer assembly 3 will respond to these pressure changes in real time, absorb and disperse the impact force through its own deformation, thereby reducing the vibration of the battery module. The arc design of the elastic body 303 can flexibly respond to impact forces of different directions and intensities, and maintain stable support for the battery module.

[0053] In addition, if Figure 2 and Figure 5 As shown, in order to reduce the friction between the middle of the elastic body 303 and the bottom of the accommodating cavity 101 , a slider 6 is fixedly connected to the middle of the elastic body 303 , and a universal ball 601 for universal rolling on the bottom of the accommodating cavity 101 is provided at the bottom of the slider 6 .

[0054] During the buffering process of the buffer component 3 on the battery module in the inner box 102, the rolling of the universal ball 601 at the bottom of the accommodating cavity 101 replaces the sliding of the middle part of the elastomer 303 at the bottom of the accommodating cavity 101, which can effectively reduce the friction between the middle part of the elastomer 303 and the bottom of the accommodating cavity 101 and increase the service life of the elastomer 303. In addition, the universal ball 601 can roll in all directions at the bottom of the accommodating cavity 101 and can adapt to the deformation of the elastomer 303.

[0055] Embodiment 2

[0056] like Figure 5-Figure 7As shown, on the basis of the first embodiment, in order to realize that the two elastic bodies 303 on the same cross bar 302 have one end close to the fixed block 301 fixed to the cross bar 302, and the end away from the fixed block 301 slides along the axis of the cross bar 302, a fixed block 4 and a movable block 5 are provided on the cross bar 302, the fixed block 4 is fixedly sleeved on the cross bar 302, and the end of the elastic body 303 close to the fixed block 301 is fixed to the fixed block 4; the movable block 5 is slidably sleeved on the cross bar 302, and the end of the elastic body 303 away from the fixed block 301 is fixed to the movable block 5, and the movable block 5 supports the bearing part 2. A first bolt 7 is provided on the fixed block 4 and is perpendicular to the axis of the cross bar 302. The threaded end of the first bolt 7 passes through the side wall of the fixed block 4 and is meshed and connected to the side wall of the cross bar 302. A second bolt 8 is provided on the moving block 5 and is perpendicular to the axis of the cross bar 302. The threaded end of the second bolt 8 passes through the side wall of the fixed block 4 and is slidably connected in a slide groove 3021 opened on the side wall of the cross bar 302. The slide groove 3021 is opened along the axial direction of the cross bar 302.

[0057] The fixed block 4 is firmly fixed on the cross bar 302 by the first bolt 7, and the end of the elastic body 303 close to the fixed block 301 is fixed on the fixed block 4, thus ensuring the stability of one end of the elastic body 303 on the cross bar 302. The moving block 5 is connected to the cross bar 302 by sliding sleeves, and is allowed to slide freely along the axis direction of the cross bar 302. The end of the elastic body 303 away from the fixed block 301 is fixed on the moving block 5, so when the moving block 5 slides, it will drive the end of the elastic body 303 to slide. The second bolt 8 passes through the moving block 5 and is slidably connected to the slide groove 3021 on the side wall of the cross bar 302. The design of the slide groove 3021 allows the second bolt 8 (moving block 5) to slide freely along the axis direction on the cross bar 302 while maintaining the connection with the cross bar 302.

[0058] When the battery module applies downward pressure to the inner box 102, the load-bearing part 2 presses down the buffer assembly 3. At this time, the elastic body 303 begins to deform, and the movable block 5 slides downward on the cross bar 302 to adapt to the downward movement of the load-bearing part 2. As the deformation of the elastic body 303 intensifies, they gradually absorb and disperse the impact force, slowing down the vibration of the battery module. When the vehicle encounters bumps during driving, the elastic body 303 and the movable block 5 will respond and adjust in real time to maintain stable support and buffering for the battery module.

[0059] Embodiment 3

[0060] like Figure 2-Figure 4As shown, on the basis of the second embodiment, in order to enable the buffer assembly 3 to perform buffering in multiple directions, four buffer assemblies 3 are provided in this embodiment, and the four buffer assemblies 3 are respectively distributed on the four sides of the accommodating cavity 101, and the projections of the cross bars 302 on the two adjacent buffer assemblies 3 to the bottom of the accommodating cavity 101 are perpendicular to each other, and the projections of the cross bars 302 on the two opposite buffer assemblies 3 to the bottom of the accommodating cavity 101 are parallel to each other;

[0061] Among them, the bearing part 2 includes a first carrier plate 201 and a second carrier plate 202, and the first carrier plate 201 and the second carrier plate 202 are arranged perpendicularly and crosswise to each other. The first carrier plate 201 is supported by movable blocks 5 on two opposite buffer components 3, and the second carrier plate 202 is supported by movable blocks 5 on another two opposite buffer components 3.

[0062] The first carrier plate 201 and the second carrier plate 202 are mounted on the buffer assembly 3 in the following manner:

[0063] Take the second carrier board 202 as an example: Figure 7 As shown, a through hole for inserting the second bolt 8 is opened on the second carrier plate 202. After the movable block 5 is sleeved on the cross bar 302, the second carrier plate 202 is placed in the accommodating chamber 101 and supported by the movable block 5. The through hole opened on the second carrier plate 202 is aligned with the threaded hole on the movable block 5, and the second bolt 8 is inserted from the through hole of the second carrier plate 202. The second bolt 8 is rotated. At this time, the second bolt 8 is engaged with the movable block 5. As the second bolt 8 is tightened, the threaded end of the second bolt 8 is inserted into the slide groove 3021. At this time, the second bolt 8 can be used to fix the second carrier plate 202 on the movable block 5 and install the movable block 5 on the cross bar 302, and the sliding range of the movable block 5 is limited by the cooperation between the second bolt 8 and the slide groove 3021.

[0064] When the battery module is placed in the inner box 102 and placed on the carrying portion 2, its weight is evenly distributed on the first carrier plate 201 and the second carrier plate 202. The two carrier plates then transfer the pressure to the buffer assembly 3 below them.

[0065] Horizontal buffering: When the vehicle encounters bumps in the horizontal direction (such as shaking left and right or shaking forward and backward), the first carrier plate 201 and the second carrier plate 202 will be subjected to pressure from the horizontal direction. For example, if the first carrier plate 201 is subjected to pressure when shaking left and right, the second carrier plate 202 will be subjected to pressure when shaking forward and backward. These pressures are transmitted to the crossbar 302 and the elastic body 303 through the moving block 5. Since the crossbars 302 of two adjacent buffer assemblies 3 are projected perpendicular to each other, they can absorb and disperse the impact force from the horizontal direction respectively.

[0066] Vertical buffering: When the vehicle encounters bumps in the vertical direction (such as up and down vibrations), the entire load-bearing part 2 will move downward as a whole. At this time, the four buffer components 3 will be subjected to downward pressure at the same time, and absorb and disperse the impact force through the deformation of the elastic body 303, working together to provide a stronger vertical buffering effect.

[0067] like Figure 2-Figure 4 As shown, in order to enable the first carrier plate 201 and the second carrier plate 202 to support the inner box 102 at the same time, the bottom plate 10 is fixedly connected to the lower end of the inner box 102, and a sink 12 is provided between the side of the bottom plate 10 and the inner box 102. Four ear plates 9 are fixed to the upper surfaces of the first carrier plate 201 and the second carrier plate 202. The side of each ear plate 9 extends upward and is plugged into the inside of the sink 12 on the same side. The width of the ear plate 9 is the same as the width of the sink 12. Figure 2 As shown in the enlarged view in , there is a gap between the ear plate 9 and the groove wall of the sink 12. For example, under the impact, when the inner box 102 moves horizontally forward and backward with the bottom plate 10, the ear plates 9 located on the front and rear sides of the bottom plate 10 slide in the sink 12 on the front and rear sides, and the ear plates 9 located on the left and right sides of the bottom plate 10 cooperate with the sink 12 on the left and right sides of the bottom plate 10, so that the buffer components 3 on the left and right sides buffer the battery modules in the inner box 102. Similarly, under the impact, when the inner box 102 moves horizontally left and right with the bottom plate 10, the ear plates 9 located on the left and right sides of the bottom plate 10 slide in the sink 12 on the left and right sides, and the ear plates 9 located on the front and rear sides of the bottom plate 10 cooperate with the sink 12 on the front and rear sides of the bottom plate 10, so that the buffer components 3 on the front and rear sides buffer the battery modules in the inner box 102. A plurality of rolling balls 11 for supporting the bottom of the bottom plate 10 are distributed on the upper surface of the ear plate 9. The arrangement of the rolling balls 11 can reduce the friction between the ear plate 9 and the bottom plate 10.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents. Any modification or partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
