[0030] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0031] At present, electric vehicle battery packs are usually equipped with at least one explosion-proof valve. When the battery is in thermal runaway, the explosion-proof valve can relieve the pressure and cool the battery pack to prevent the battery pack from exploding due to the accumulation of high-temperature and high-pressure gas. However, the current explosion-proof valve cannot allow the high-temperature gas to erupt in a directional manner. If the high-temperature gas is ejected in all directions without restriction, it is easy to cause damage to the vehicle or the people or objects around it.

[0032] Reference below Figure 1-Figure 3 A battery pack assembly according to an embodiment of the present invention is described.

[0033] According to the utility model, the battery pack assembly includes a battery pack explosion-proof valve body 11 and a cover body 12. The explosion-proof valve body 11 is suitable for being connected to the battery pack and an air flow channel connected to the interior of the battery pack is formed in the explosion-proof valve body 11; the cover body 12 is movably arranged on the explosion-proof valve body 11 to open or close the air flow channel; wherein, when the cover body 12 opens the air flow channel, a side surface of the cover body 12 facing the air flow channel is inclined toward the bottom of the vehicle in the opening direction of the air flow channel.

[0034] According to the battery pack assembly of the utility model, an explosion-proof valve body 11 is provided on the battery pack, and an air flow channel is formed in the explosion-proof valve body 11, and the air flow channel is connected to the inside of the battery pack. When the battery pack is thermally runaway, the high-temperature gas can be discharged to the outside through the air flow channel to avoid the battery pack from exploding due to the sudden accumulation of high-temperature gas. A cover body 12 is also provided on the explosion-proof valve body 11, and the cover body 12 is movably connected to the explosion-proof valve body 11. When the battery pack is thermally runaway, the high-temperature airflow enters the air flow channel and impacts the cover body 12. At this time, the cover body 12 can move relative to the explosion-proof valve body 11 to open the air flow channel to discharge the high-temperature gas. It is worth noting that when the cover body 12 opens the air flow channel, the side surface of the cover body 12 facing the air flow channel is inclined toward the bottom of the vehicle in the opening direction of the air flow channel. The inclined cover body 12 can guide the high-temperature gas so that the high-temperature gas is ejected toward the bottom of the vehicle, avoiding the high-temperature gas directly impacting the vehicle and causing damage to the vehicle, realizing the directional discharge of the high-temperature gas generated when the battery pack is out of control, and improving the safety of the battery pack.

[0035] According to an embodiment of the utility model, the cover 12 is flippably disposed on the explosion-proof valve body 11. When the explosion-proof valve needs to release pressure, the cover 12 flips to open the airflow channel so that the airflow can flow out in a preset direction. Compared with other movement modes, the flip design of the cover 12 can improve the efficiency of the cover 12 in opening the airflow channel.

[0036] According to one embodiment of the utility model, the cover body 12 is provided with a pivot shaft 13 so as to be pivotally arranged on the explosion-proof valve body 11, and the pivot shaft 13 is arranged at the top edge of the open mouth of the airflow channel. Specifically, the top edge of the cover body 12 can be provided with a pivot shaft 13 so that the cover body 12 and the explosion-proof valve body 11 can be rotatably connected. When the battery pack is out of control, the high-temperature airflow impacts the cover body 12 so that the cover body 12 rotates around the pivot shaft 13 and opens the airflow channel. At this time, the cover body 12 is rotated with the pivot shaft 13 at the top edge of the cover body 12 as the rotation axis. Therefore, after the cover body 12 rotates a certain angle, it tilts toward the bottom of the vehicle to guide the high-temperature gas, thereby realizing the function of the battery pack assembly to discharge the high-temperature gas in a directional manner.

[0037] According to an embodiment of the utility model, the top edge of the explosion-proof valve body 11 is provided with a first pivot portion 111, the top edge of the cover body 12 is provided with a second pivot portion 121, and the pivot shaft 13 is connected to the second pivot portion 121 and passes through the first pivot portion 111 so that the second pivot portion 121 is rotatably connected to the first pivot portion 111. Specifically, the top edge of the explosion-proof valve body 11 is provided with a first pivot portion 111, and the top edge of the cover body 12 is provided with a second pivot portion 121. During assembly, the pivot shaft 13 sequentially passes through the first pivot portion 111 and the second pivot portion 121, so that the cover body 12 and the explosion-proof valve body 11 can both rotate around the pivot shaft 13 as the axis, thereby improving the flexibility of the cover body 12 to rotate relative to the explosion-proof valve body 11.

[0038] According to an embodiment of the utility model, the battery pack assembly further includes a reset member 14, which is disposed on the explosion-proof valve body 11 and connected to the cover body 12, and is suitable for guiding the cover body 12 to reset after the high-temperature airflow is discharged. Specifically, the battery pack assembly can be provided with a reset member 14 connected to the cover body 12 in the explosion-proof valve body 11, and when the battery pack is depressurized and the high-temperature gas is discharged through the airflow channel, the reset member 14 can drive the cover body 12 to reset to close the airflow channel, thereby preventing external water mist or other gases from entering the battery pack and affecting the safety of the battery pack.

[0039] According to one embodiment of the utility model, the reset member 14 includes a fixed seat 141, a connecting member 142 and an elastic member. The fixed seat 141 is arranged on the side of the explosion-proof valve body 11 away from the cover body 12 and an accommodating cavity is formed in the fixed seat 141; at least part of the connecting member 142 is movably accommodated in the accommodating cavity and connected to the cover body 12; the elastic member is arranged in the accommodating cavity and connects the connecting member 142 to the fixed seat 141, and the elastic member is suitable for driving the cover body 12 to rotate after the high-temperature airflow is discharged.

[0040] The reset member 14 is provided with a fixed seat 141, a connecting member 142 and an elastic member, wherein the fixed seat 141 is a structure for fixing and supporting the reset member 14 as a whole, and the fixed seat 141 is arranged on the side of the explosion-proof valve body 11 away from the cover body 12, thereby avoiding the assembly of the fixed seat 141 and the interference of the cover body 12, thereby improving the space utilization rate; an accommodating cavity is formed in the fixed seat 141, one end of the connecting member 142 is connected to the cover body 12, and the other end of the connecting member 142 is movably accommodated in the accommodating cavity, and the connecting member 142 can be driven to move when the cover body 12 rotates. The setting of the accommodating cavity avoids the connection member 142 from being separated from the fixed seat 141 after the cover body 12 rotates and cannot be reset; an elastic member is also arranged between the fixed seat 141 and the connecting member 142, which can also be understood as: the elastic member is arranged on the bottom wall of the accommodating cavity and connected to the connecting member 142, and the elastic member can apply a pulling force to the connecting member 142 to reset the connecting member 142. Specifically, when the battery pack experiences thermal runaway, the high-temperature gas impacts the cover body 12, and the cover body 12 is forced to rotate and open the air flow channel, and the high-temperature gas flows out to the outside through the air flow channel. At this time, the elastic member is in a stretched state. After the battery pack is depressurized, the cover body 12 is no longer impacted by the high-pressure gas. The elastic member pulls the connecting member 142 to drive the cover body 12 to reset and close the air flow channel, thereby preventing impurities such as water mist from the outside from entering the battery pack and causing safety hazards.

[0041] According to an embodiment of the present invention, the connecting member 142 includes a slider 1421 and a pivoting member 1422. The slider 1421 is received in the receiving cavity; the pivoting member 1422 is hinged to the slider 1421 and the cover 12. Since the connecting member 142 is connected to the cover 12, and the connecting seat is movably received in the receiving cavity, the structure of the connecting member 142 affects the rotation of the cover 12. Specifically, the connecting member 142 is provided with a slider 1421 and a pivot member 1422, wherein at least a portion of the slider 1421 is accommodated in the accommodating cavity and can slide in the accommodating cavity; the pivot member 1422 connects the slider 1421 and the cover body 12, the slider 1421 can rotate relative to the pivot member 1422, and the cover body 12 can also rotate relative to the pivot member 1422. When the cover body 12 is reset, the slider 1421 is driven by the elastic member to slide toward the bottom wall of the accommodating cavity in the accommodating cavity, and the pivot member 1422 is driven to drive the cover body 12 to rotate. The setting of the pivot member 1422 can prevent the mutual interference between the axial movement of the slider 1421 and the rotation of the cover body 12, thereby improving the flexibility of the rotation of the cover body 12.

[0042] According to one embodiment of the utility model, a first groove 14211 is formed at one end of the slider 1421 facing the cover body 12, and a protrusion 122 is provided on the side of the cover body 12 facing the explosion-proof valve body 11, and a second groove 1221 is formed on the protrusion 122; a first sphere 14221 and a second sphere 14222 are respectively formed at both ends of the pivot member 1422, the first sphere 14221 is accommodated in the first groove 14211, and the second sphere 14222 is suitable for being accommodated in the second groove 1221. The first sphere 14221 can rotate in the first groove 14211, and the second sphere 14222 can rotate in the second groove 14221. When the battery pack is thermally runaway and generates high-temperature gas, the high-temperature gas impacts the cover 12, and the cover 12 rotates relative to the second sphere 14222, while pulling the second sphere 14222 to move. The second sphere 14222 can drive the first sphere 14221 to move. In this process, the first sphere 14221 can rotate in the first groove 14211 and pull the slider 1421 to move, which can be simply It is understood that the cover body 12 rotates relative to the pivot member 1422 through the cooperation between the second groove 1221 and the second sphere 14222, and the second pivot members 1422 rotate relative to the slider 1421 through the cooperation between the first sphere 14221 and the first groove 14211. The cooperation between the first sphere 14221 and the first groove 14211 and the cooperation between the second sphere 14222 and the second groove 1221 can improve the flexibility of the movement of the cover body 12 and the reset member 14, so that the battery pack can respond quickly to open the air flow channel for pressure relief in the event of thermal runaway.

[0043] According to an embodiment of the utility model, a first support rib 151 and a second support rib 152 are orthogonal to each other in the air flow channel, and the fixing seat 141 is respectively connected to the first support rib 151 and the second support rib 152. The first support rib 151 and the second support rib 152 are orthogonal to each other and are respectively connected to the inner wall of the air flow channel, thereby improving the structural strength of the explosion-proof valve body 11. During assembly, the fixing seat 141 can be arranged at the connection between the first support rib 151 and the second support rib 152 to improve the stability of the fixing seat 141 assembly.

[0044] In some embodiments, a support portion 153 is formed at the connection between the first support rib 151 and the second support rib 152, and a through hole 154 is formed on the support portion 153 and passes through the extension direction of the airflow channel. The slider 1421 can pass through the through hole 154 and then extend into the accommodating cavity. The setting of the support portion 153 can improve the stability of the slider 1421 during movement.

[0045] According to an embodiment of the utility model, a first seal 161 is provided between the cover 12 and the explosion-proof valve body 11, and a second seal 162 is provided on the side of the explosion-proof valve body 11 away from the cover 12. During assembly, the battery pack assembly may also be provided with a first seal 161 and a second seal 162, wherein the first seal 161 is provided between the cover 12 and the explosion-proof valve body 11, and the second seal 162 is provided between the explosion-proof valve body 11 and the battery pack. The provision of the first seal 161 can improve the sealing effect between the cover 12 and the explosion-proof valve body 11, and prevent external water mist from entering the battery pack from the gap between the cover 12 and the explosion-proof valve body 11; the provision of the second seal 162 can improve the sealing effect between the explosion-proof valve body 11 and the battery pack, and prevent external water mist from entering the battery pack from the gap between the explosion-proof valve body 11 and the battery pack assembly position, thereby improving the safety of the battery pack.
