The electric toy may include a stationary or mobile electric toy, such as a game machine, an electric car toy, an electric ship toy, an electric airplane toy, and the like, and the spacecraft may include an airplane, a rocket, a space shuttle, a spacecraft, and the like.
For convenience of description, the following embodiments take an example in which a power consuming apparatus according to an embodiment of the present application is a vehicle 1000.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a vehicle 1000 according to some embodiments of the present disclosure. The vehicle 1000 may be a fuel automobile, a gas automobile, or a new energy automobile, and the new energy automobile may be a pure electric automobile, a hybrid electric automobile, or an extended range automobile, etc. The battery module 100 is provided inside the vehicle 1000, and the battery module 100 may be provided at the bottom or the head or the tail of the vehicle 1000. The battery module 100 may be used for power supply of the vehicle 1000, and for example, the battery module 100 may serve as an operation power source of the vehicle 1000. The vehicle 1000 may further include a controller 200 and a motor 300, wherein the controller 200 is used for controlling the battery module 100 to supply power to the motor 300, for example, for starting, navigating and driving of the vehicle 1000.
In some embodiments of the present application, the battery module 100 may be used not only as an operating power source of the vehicle 1000, but also as a driving power source of the vehicle 1000, instead of or partially in place of fuel or natural gas, to provide driving power for the vehicle 1000.
Fig. 2 to 4 respectively show a perspective view of the battery module 100 provided in one embodiment of the present disclosure, an exploded view of the battery module 100 provided in one embodiment of the present disclosure, and a cross-sectional view of the plane a of fig. 2. The battery module 100 includes a cell module 10, a bumper frame 20, and a bumper 40. The cell module 10 includes a first surface 11, a second surface 12, a first side 13, a second side 14, and a third side 15. First surface 11 and second surface 12 set up relatively, first side 13 is connected with first surface 11 and second surface 12 respectively, second side 14 is connected with first surface 11 and second surface 12 respectively, third side 15 is connected with first surface 11 and second surface 12 respectively, second side 14 is connected with first side 13 and third side 15 respectively, first side 13 and third side 15 set up relatively, electric core module 10 is equipped with utmost point post 16, utmost point post 16 sets up in first side 13 and/or third side 15. The crash frame 20 is provided with an accommodating space 21, the battery cell module 10 is accommodated in the accommodating space 21, and a gap 30 is formed between the first side surface 13 and/or the third side surface 15 provided with the pole 16 and the crash frame 20. The impact prevention member 40 is disposed in the gap 30, and one side of the impact prevention member 40 abuts against the inner surface of the impact frame 20, and the other side of the impact prevention member 40 abuts against the end of the first side 13 and/or the third side 15 provided with the pole 16 connected to one end of the second side 14.
It is understood that the design is such that, when the vehicle 1000 is pressed or bumped, the battery module 100 is deformed by the pressing or bumping. Meanwhile, the impact frame 20 is a buffering and energy absorbing structure, and at this time, the impact frame 20 is firstly subjected to impact force generated by extrusion or impact, and under the action of the impact force, the impact frame 20 collapses to perform first-step buffering and energy absorption. Secondly, the impact protection 40 can absorb energy a further step, on the one hand, and, on the other hand, transmit the remaining energy from the impact protection 40 to the end of the first side 13 and/or the third side 15 provided with the pole 16 connected to the second side 14 via the connection of the impact protection 40 to the crash frame 20. For the cell module 10, the end portion of the first side 13 connected to the second side 14 has a better force-bearing capacity. The force-bearing capacity is stronger because the end portions where the first side 13 and the second side 14 are connected are relatively larger in bending moment than the middle regions facing away from the end portions. It is worth mentioning that the cell module 10 is further provided with an explosion-proof valve 17, the explosion-proof valve 17 is used as a pressure relief device, and the explosion-proof valve 17 is disposed adjacent to the pole 16 and is disposed on the first side 13 and/or the third side 15 of the cell module 10. So that the impact frame 20 and the impact prevention member 40 can sequentially receive the impact force generated by the external compression or impact to protect the pole 16 and the explosion-proof valve 17. It should be noted that, when the terminal post 16 or the explosion-proof valve 17 is damaged by extrusion or impact, the cell module 10 may be thermally out of control due to the damage of the terminal post 16 or the explosion-proof valve 17, and further cause the cell module 10 to burn or explode. That is, the terminal post 16 is disposed on the cell module 10, and the anti-collision member 40 is disposed between the cell module 10 and the anti-collision frame 20, so that the anti-collision frame 20 and the anti-collision member 40 can sequentially bear the impact force generated by external extrusion or impact, so as to protect the terminal post 16 and the anti-explosion valve 17. For convenience of description, the cell module 10 in fig. 3 schematically includes only one cell, and it can be understood by those skilled in the art that the cell module 10 may also include a plurality of cell units, and when the cell module includes a plurality of cell units, the terminal posts of the cell module are disposed on the first side 13 and/or the third side 15.
In some embodiments, please refer to fig. 5 to 6 in combination with other drawings, which show perspective views of the battery cell module 10 and the bumper 40 provided in one embodiment of the present application. The bumper 40 includes a plurality of bumper blocks arranged at intervals.
Specifically, the plurality of crash blocks includes a first crash block 41, a second crash block 42, a third crash block 43, and a fourth crash block 44. The first bumper block 41 is located on one side of the end of the first side 13 and/or the third side 15 connected to the second side 14 close to the first surface 11, and the second bumper block 42 is located on one side of the end of the first side 13 and/or the third side 15 connected to the second side 14 close to the second surface 12. The third anti-collision block 43 is located on one side of the other end, close to the first surface 11, of the first side surface 13 and/or the third side surface 15, which is connected to the second side surface 14, and the fourth anti-collision block 44 is located on one side, close to the second surface 12, of the other end, close to the second surface 12, of the first side surface 13 and/or the third side surface 15, which is connected to the second side surface 14. That is, the first, second, third, and fourth anti-collision blocks 41, 42, 43, and 44 are respectively disposed at four corners of one side surface where the post 16 is disposed, so that the post 16 and the explosion-proof valve 17 do not need to be directly subjected to an impact force from the anti-collision frame 20 to protect the post 16 and the explosion-proof valve 17. It should be noted that the first anti-collision block 41, the second anti-collision block 42, the third anti-collision block 43 and the fourth anti-collision block 44 are all arranged in a rectangular block shape, and in other embodiments, the first anti-collision block may also be cylindrical, or may extend along the outer edge of the first side surface 13 and/or the third side surface 15 to form an "L" shape and be arranged at the corner, and the patent does not limit the specific shape of the anti-collision block.
It should be noted that, for the cell module 10, the pressure that can be borne by the cell module 10 is greater than the pressure that deviates from the middle area of the two sides, where one end of the first side surface 13 connected to the second side surface 14 is close to one side of the first surface 11, and one end of the first side surface 13 connected to the second side surface 14 is close to one side of the second surface 12. The reason is that the bending moment of the middle area of the cell module 10 away from the two sides is greater than that of the two sides, and therefore the cell module is easily deformed by pressure, so that the first anti-collision block 41 and the second anti-collision block 42 are respectively disposed on the two sides with smaller bending moment, and similarly, the third anti-collision block 43 and the fourth anti-collision block 44 are respectively disposed on the two sides with smaller bending moment away from the second side surface 14. It is understood that the first, second, third and fourth impact-prevention blocks 41, 42, 43 and 44 may also partially extend to the second side surface 14, thereby further improving the impact resistance of the battery module 100 in more directions.
