DETAILED DESCRIPTION

[0071] In order to enable a more complete understanding of the above-mentioned purposes, features and advantages of the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0072] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, however, the present application can also be implemented in other ways different from those described herein, therefore, the protection scope of the present application is not limited by the specific embodiments disclosed below.

[0073] The following refers to Figures 1 to 10 The battery storage device 4, the battery assembly 3, the electrical equipment 1 and the energy storage device 2 of some embodiments of the present application are described.

[0074] At present, new energy batteries are more and more widely used in life and industry. New energy is not only applied to energy storage power supply systems such as hydroelectric, thermal, wind and solar power stations, but also widely used in electric bicycles, electric motorcycles, electric vehicles and other electric vehicles in many fields. With the continuous expansion of the application field of power batteries, the market demand is also increasing.

[0075] When the battery device 30 of the power battery is not assembled in the electric equipment 1 or the energy storage equipment 2, the battery device 30 needs to be transported or stored somewhere. The battery device 30 includes battery monomers. The battery device 30 can also be a battery module, a battery pack, and other forms of energy storage devices such as an electric cabinet. If the battery device 30 is directly placed in the external environment, the air, water and dirt in the external environment will directly contact the battery device 30, which will corrode the shell of the battery device 30, resulting in electrolyte leakage. If the battery device 30 is directly placed in the external environment, the mechanical impact force will directly act on the battery device 30, so that the shell of the battery device 30 will be deformed, and then the electrolyte leakage is easy to occur. Electrolyte leakage not only leads to the decline of battery performance and shortens the service life of the battery device 30, but also may cause more serious safety problems, such as short circuit, fire and even explosion.

[0076] In the related art, by setting a battery storage device, a cavity is arranged in the battery storage device, and the battery device is placed in the battery storage device, the battery device in the battery storage device is protected by the battery storage device, so that the battery device is isolated from the external environment, and the mechanical impact force directly acting on the battery device is reduced. However, no structure is arranged in the battery storage device to fix and protect the battery device. In order to enable the battery device to be smoothly placed in the cavity, the size of the cavity is greater than that of the battery device, that is, a gap is formed between the battery device and the cavity wall of the cavity. In this way, when the battery storage device is subjected to mechanical impact, the battery device will hit the cavity wall of the cavity, and the shell of the battery device will be deformed, which is easy to cause the battery device to leak. It can be understood that the size of the cavity is fixed, and therefore the battery storage device can only store one battery device 30 of a fixed size, and cannot meet the use demand of storing battery devices 30 of different sizes.

[0077] In view of the above, in order to reduce the probability of battery device 30 leakage, effectively protect battery device 30, and enable battery storage device 4 to store battery devices 30 of different sizes, the present application provides a battery storage device 4, which comprises a shell assembly 40 and an adjusting and protecting assembly 41, the adjusting and protecting assembly 41 comprising an adjusting structure 411 and a buffer structure 44. The shell assembly 40 and the adjusting and protecting assembly 41 cooperate to effectively fix battery device 30. When the battery storage device 4 is subjected to mechanical impact, the shell assembly 40 and the adjusting and protecting assembly 41 cooperate to effectively fix battery device 30 while slowing down the external force acting on battery device 30, thereby reducing the probability of deformation of the shell of battery device 30 and reducing the probability of battery device 30 leakage. At the same time, since the distance between the adjusting plate 412 and the positioning surface 428 of the battery storage device 4 is adjustable, the distance between the adjusting plate 412 and the positioning surface 428 can be adjusted adaptively according to the size of the shape of battery device 30, so as to achieve the purpose that the battery storage device 4 can store battery devices 30 of different sizes.

[0078] The battery storage device 4 disclosed in the present application is used to store battery device 30. After battery device 30 is placed in the battery storage device 4, the battery storage device 4 can effectively protect battery device 30, not only reducing the frequency of contact between water, air, dirt and other substances in the external environment and battery device 30, but also reducing the probability of battery device 30 leakage due to external force impact. In addition, when battery device 30 leaks, the battery storage device 4 can also reduce the probability of liquid flowing into the external environment, without polluting the external environment. When it is necessary to transport battery device 30, battery device 30 can be placed in the battery storage device 4, and the battery storage device 4 is moved to protect battery device 30 during transportation. When it is necessary to install battery device 30 in the electric device 1 or the energy storage device 2, battery device 30 can be taken out of the battery storage device 4 and installed in the electric device 1 or the energy storage device 2 correspondingly.

[0079] When battery device 30 is a battery pack, the battery pack can be used in an electric device 1 using a battery as a power source. The battery pack can also be used in various energy storage devices 2 using a battery as an energy storage element. The electric device 1 includes but is not limited to a mobile phone, a tablet, a notebook computer, an electric toy, an electric tool, an electric vehicle, an electric car, a ship, a spacecraft, etc. Among them, the electric toy can include a fixed or mobile electric toy, such as a game console, an electric car toy, an electric ship toy, an electric plane toy, etc., and the spacecraft can include an airplane, a rocket, a space shuttle, a spacecraft, etc. The energy storage device 2 includes an energy storage container, an energy storage cabinet, and a battery swap station, etc. The battery pack includes a battery module, which is a component of the battery pack.

Alternatively, the pressure detecting member 45 is disposed on the adjusting structure 411, and is used to detect the pressure at the positioning surface 428. Alternatively, the pressure detecting member 45 is disposed on the cavity wall of the cavity 401 and on the adjusting structure 411, and is used to detect the pressure at the positioning surface 428. The shell assembly 40 has the cavity 401, and the adjusting and protecting assembly 41 is disposed in the cavity 401. When the battery device 30 is placed in the battery storage device 4, the battery device 30 is also located in the cavity 401. The shell assembly 40 provides a containing space for the adjusting and protecting assembly 41 and the battery device 30, that is, the shell assembly 40 serves as a mounting carrier for the adjusting and protecting assembly 41 and the battery device 30. It can be understood that the cavity 401 is a hollow cavity, and the cavity 401 is a closed cavity to isolate the battery device 30 from air, water, dirt and the like in the external environment. The shell assembly 40 can have various shapes, such as a cylinder, a cuboid, and the like, which are not listed one by one. Even if the battery device 30 located in the cavity 401 leaks, the shell assembly 40 can collect and store the electrolyte, thereby reducing the probability of the electrolyte flowing into the external environment. The material of the shell assembly 40 includes, but is not limited to, copper, iron, aluminum, stainless steel, and aluminum alloy.

[0082] The adjusting and protecting assembly 41 not only has the function of fixing the battery device 30, but also has the function of protecting the battery device 30. When the battery storage device 4 is subjected to mechanical impact, the adjusting and protecting assembly 41 can not only limit the battery device 30, but also slow down the external force acting on the battery device 30, so that the battery device 30 will not collide with the cavity wall of the cavity 401, the probability of deformation of the battery device 30 can be reduced, and the probability of liquid leakage of the battery device 30 due to a large deformation amount can be reduced.

[0083] The adjusting and protecting assembly 41 comprises an adjusting structure 411 and a buffering structure 44. The adjusting structure 411 and the buffering structure 44 are component parts of the adjusting and protecting assembly 41. The adjusting structure 411, the buffering structure 44 and the shell assembly 40 cooperate with each other to adaptively adjust the distance between the adjusting plate 412 and the positioning face 428 according to the size of the battery device 30, so as to effectively clamp and fix the battery device 30. The contact face 441 of the buffering structure 44 abuts against the battery device 30, so as to slow down the external force acting on the battery device 30.

[0084] The adjusting structure 411 comprises the adjusting plate 412 and a driving part 418. The driving part 418 is connected with the adjusting plate 412. The driving part 418 is used to drive the adjusting plate 412 to move relative to the shell assembly 40. It can be understood that there is a gap between the outer peripheral wall of the adjusting plate 412 and the cavity wall of the cavity 401. The adjusting plate 412 can move in the cavity 401 under the action of the driving part 418, and the cavity wall of the cavity 401 will not interfere with the adjusting plate 412.

[0085] One of the cavity wall of the cavity 401 and the adjusting structure 411 has the positioning face 428, which is used to abut against one side end face of the battery device 30 to limit the battery device 30. The cavity wall of the cavity 401 has the positioning face 428, or part of the cavity wall of the cavity 401 forms the positioning face 428. Alternatively, the adjusting structure 411 has the positioning face 428.

[0086] The positioning face 428 is arranged opposite and spaced apart from the adjusting plate 412, that is, the positioning face 428 is arranged opposite the adjusting plate 412, and there is a gap between the positioning face 428 and the adjusting plate 412. Specifically, the adjusting plate 412 and the positioning face 428 enclose a clamping area 431, and the battery device 30 is located in the clamping area 431.

[0087] The buffering structure 44 has a contact face 441, which is located in the clamping area 431. At least one of the side of the adjusting plate 412 facing the positioning face 428 and the cavity wall of the cavity 401 is connected with the buffering structure 44. The contact face 441 is used to contact and abut against the battery device 30.

[0088] The side of the adjusting plate 412 facing the positioning surface 428 is connected with the buffer structure 44, and the contact surface 441 of the buffer structure 44 is located in the clamping area 431.

[0089] Alternatively, the cavity wall of the cavity 401 is connected with the buffer structure 44, and the contact surface 441 of the buffer structure 44 is located in the clamping area 431.

[0090] Alternatively, the side of the adjusting plate 412 facing the positioning surface 428 and the cavity wall of the cavity 401 are both connected with the buffer structure 44, and the contact surface 441 of the buffer structure 44 is located in the clamping area 431. The contact surface 441 includes a first sub-surface 445 and a second sub-surface 446. The part of the buffer structure 44 connected with the adjusting plate 412 has the first sub-surface 445, the part of the buffer structure 44 connected with the cavity wall of the cavity 401 has the second sub-surface 446, the battery device 30 abuts between the first sub-surface 445 and the positioning surface 428, and the second sub-surface 446 abuts with the battery device 30.

[0091] In the case that the side of the adjusting plate 412 facing the positioning surface 428 is connected with the buffer structure 44, and the contact surface 441 of the buffer structure 44 is located in the clamping area 431, the battery device 30 is located between the contact surface 441 of the buffer structure 44 and the positioning surface 428. When the driving part 418 drives the adjusting plate 412 to move relative to the shell assembly 40, the distance between the adjusting plate 412 and the positioning surface 428 can be adjusted, and thus the distance between the contact surface 441 and the positioning surface 428 can be adjusted, so as to effectively clamp and fix the battery device 30 by the contact surface 441 and the positioning surface 428. When the battery storage device 4 is subjected to mechanical impact, the contact surface 441 of the buffer structure 44 will move relative to the positioning surface 428 under the action of the impact force, so as to absorb or dissipate the energy of the external force impact, thereby slowing down the impact force transmitted to the battery device 30, so as to reduce the probability of deformation of the battery device 30.

[0092] In the case that the cavity wall of the cavity 401 is connected with the buffer structure 44, and the contact surface 441 of the buffer structure 44 is located in the clamping area 431, the battery device 30 is located between the adjusting plate 412 and the positioning surface 428. When the driving part 418 drives the adjusting plate 412 to move relative to the shell assembly 40, the distance between the adjusting plate 412 and the positioning surface 428 can be adjusted, so as to effectively clamp and fix the battery device 30 by the adjusting plate 412 and the positioning surface 428, and since the contact surface 441 is located in the clamping area 431, the contact surface 441 can contact and abut with the battery device 30. When the battery storage device 4 is subjected to mechanical impact, the contact surface 441 of the buffer structure 44 will move relative to the shell assembly 40 under the action of the impact force, so as to absorb or dissipate the energy of the external force impact, thereby slowing down the impact force transmitted to the battery device 30, so as to reduce the probability of deformation of the battery device 30.

[0093] In the case that the side of the adjusting plate 412 facing the locating surface 428 and the cavity wall of the cavity 401 are both connected with the buffer structure 44, the contact surface 441 of the buffer structure 44 is located in the clamping area 431. The contact surface 441 includes a first sub-surface 445 and a second sub-surface 446. The part of the buffer structure 44 connected with the adjusting plate 412 has the first sub-surface 445, and the part of the buffer structure 44 connected with the cavity wall of the cavity 401 has the second sub-surface 446. When the driving part 418 drives the adjusting plate 412 to move relative to the shell assembly 40, the distance between the adjusting plate 412 and the locating surface 428 can be adjusted, and thus the distance between the first sub-surface 445 and the locating surface 428 can be adjusted, so as to effectively clamp and fix the battery device 30 by the first sub-surface 445 and the locating surface 428, while the second sub-surface 446 is in contact with and abuts against the battery device 30. When the battery storage device 4 is subjected to a mechanical impact, the first sub-surface 445 moves relative to the locating surface 428 under the impact force, and the second sub-surface 446 moves relative to the shell assembly 40 under the impact force. The first sub-surface 445 and the second sub-surface 446 cooperate to absorb or dissipate the energy of the external force impact from multiple positions and multiple directions, so as to slow down the impact force transmitted to the battery device 30, thereby reducing the probability of deformation of the battery device 30.

[0094] It can be understood that the contact surface 441 of the buffer structure 44 is located in the clamping area 431, and the contact surface 441 can effectively contact the battery device 30, and the contact surface 441 is used to contact and abut against the battery device 30.

[0095] Since the distance between the adjusting plate 412 and the locating surface 428 is adjustable, the battery storage device 4 can store battery devices 30 of different sizes. For example, in the case that the side of the adjusting plate 412 facing the locating surface 428 is connected with the buffer structure 44, when it is needed to store a battery pack in the battery storage device 4, the driving part 418 drives the adjusting plate 412 to move away from the locating surface 428, and the contact surface 441 moves away from the locating surface 428, so as to increase the distance between the contact surface 441 and the locating surface 428. Then, the battery pack is placed in the clamping area 431, and the driving part 418 drives the adjusting plate 412 to move again to adaptively adjust the distance between the contact surface 441 and the locating surface 428 according to the shape of the battery pack, until the contact surface 441 and the locating surface 428 clamp the battery pack. When it is needed to store a battery module in the battery storage device 4, the driving part 418 drives the adjusting plate 412 to move towards the locating surface 428, and the contact surface 441 moves towards the locating surface 428, so as to decrease the distance between the contact surface 441 and the locating surface 428. Then, the battery module is placed in the clamping area 431, and the driving part 418 drives the adjusting plate 412 to move again to adaptively adjust the distance between the contact surface 441 and the locating surface 428 according to the shape of the battery module, until the contact surface 441 and the locating surface 428 clamp the battery pack.

[0096] Therefore, the shell assembly 40 and the adjusting protection assembly 41 cooperate to fix and limit the battery device 30 effectively, and to slow down the external force acting on the battery device 30 when the battery storage device 4 is subjected to mechanical impact, thereby reducing the probability of deformation of the battery device 30 and reducing the probability of liquid leakage of the battery device 30. When storing and transporting the battery device 30, the battery storage device 4 can effectively protect the battery device 30. At the same time, the battery storage device 4 can also meet the use demand of storing battery devices 30 of different sizes, and improve the use adaptability of the battery storage device 4.

[0097] The battery storage device 4 further comprises a pressure detection member 45, and the detection data of the pressure detection member 45 is used to confirm the pressure at the positioning surface 428.

[0098] The pressure detection member 45 is arranged on at least one of the cavity wall of the cavity 401 and the adjusting structure 411. That is, the pressure detection member 45 is arranged on the cavity wall of the cavity 401. Alternatively, the pressure detection member 45 is arranged on the adjusting structure 411. Alternatively, the pressure detection member 45 is arranged on the cavity wall of the cavity 401, and the pressure detection member 45 is also arranged on the adjusting structure 411. At least one of the cavity wall of the cavity 401 and the adjusting structure 411 serves as a mounting carrier of the pressure detection member 45, and has the function of mounting and fixing the pressure detection member 45.

[0099] It can be understood that the pressure detection member 45 is located at the positioning surface 428, and the pressure detection member 45 is used to detect the pressure at the positioning surface 428.

[0100] Exemplarily, when the positioning plate 425 forms the positioning surface 428, the positioning plate 425 and the pressure detection member 45 are integrally connected, and the combination structure of the positioning plate 425 and the pressure detection member 45 can be referred to as a pressure plate.

[0101] Exemplarily, when the cavity wall of the cavity 401 forms the positioning surface 428, the cavity wall of the cavity 401 and the pressure detection member 45 are integrally connected, and the combination structure of the shell assembly 40 and the pressure detection member 45 can be referred to as a pressure shell.

[0102] Therefore, when the battery device 30 is assembled, the driving part 418 drives the adjusting plate 412 to move towards the positioning surface 428 to reduce the distance between the adjusting plate 412 and the positioning surface 428, so as to achieve the effect of fixing the battery device 30. Since the pressure detection part 45 is arranged, the pressure on the positioning surface 428 due to the extrusion of the adjusting plate 412 on the battery device 30 can be known through the pressure detection part 45. When the pressure value at the positioning surface 428 is within the target range, the driving part 418 stops driving the adjusting plate 412 to move. At this time, the battery device 30 has been effectively fixed. In this way, the probability of deformation of the battery device 30 due to excessive pressure for extruding and fixing the battery device 30 can be reduced, and the probability of the battery device 30 not being effectively fixed due to insufficient pressure for extruding and fixing the battery device 30 can be reduced, thereby providing structural support for the adjusting and protecting assembly 41 to effectively fix and protect the battery device 30. In some embodiments, as shown in FIG. 2, the number of the adjusting and protecting assemblies 41 is multiple. The multiple adjusting and protecting assemblies 41 are arranged at intervals. Figure 4

[0103] The number of the adjusting and protecting assemblies 41 is multiple, and the multiple adjusting and protecting assemblies 41 are all located in the cavity 401. Each adjusting and protecting assembly 41 can fix and protect one battery device 30. When the number of the adjusting and protecting assemblies 41 is multiple, the multiple adjusting and protecting assemblies 41 can be used to simultaneously fix and protect multiple battery devices 30. The sizes of the multiple battery devices 30 can be the same or different. Of course, according to actual use requirements, only part of the multiple adjusting and protecting assemblies 41 can be used.

[0104] Specifically, the number of the adjusting and protecting assemblies 41 is n, when m battery devices 30 need to be stored, only m adjusting and protecting assemblies 41 need to be used to fix and protect the m battery devices 30, and when n battery devices 30 need to be stored, n adjusting and protecting assemblies 41 need to be used to fix and protect the n battery devices 30, wherein n is a positive integer greater than or equal to 2, m is a positive integer less than or equal to 1, and m < n.

[0105] That is to say, the battery storage device 4 can store multiple battery devices 30, and the battery storage device 4 can also store only one battery device 30. Multiple means greater than or equal to 2.

[0106] Further, the multiple adjusting and protecting assemblies 41 are arranged at intervals. There is a gap between any two adjacent adjusting and protecting assemblies 41, and interference does not occur between any two adjacent adjusting and protecting assemblies 41, thereby providing a space for disassembling and assembling the battery device 30, and simplifying the difficulty of disassembling and assembling the battery device 30.

[0107] ​Exemplarily, the plurality of adjustment protection assemblies 41 are arranged in a matrix. For example, the plurality of adjustment protection assemblies 41 can be arranged in a structure of one row and multiple columns. For example, the plurality of adjustment protection assemblies 41 can be arranged in a structure of multiple rows and multiple columns.

[0108] Therefore, by arranging the plurality of adjustment protection assemblies 41, the battery storage device 4 can meet the use requirement of storing multiple battery devices 30 at the same time, and the use adaptability of the battery storage device 4 is improved.

[0109] In some other embodiments, one adjustment protection assembly 41 is arranged in the cavity 401.

[0110] In some embodiments, as shown in Figure 3 The number of the positioning surfaces 428 in the adjustment protection assembly 41 is multiple, and the number of the adjustment plates 412 is multiple. Each adjustment plate 412 cooperates with one positioning surface 428. The plurality of adjustment plates 412 at least includes a first adjustment plate 413 and a second adjustment plate 414. The plurality of positioning surfaces 428 at least includes a first positioning surface 429 and a second positioning surface 430. The first adjustment plate 413 and the first positioning surface 429 are arranged at intervals along a first direction. The second adjustment plate 414 and the second positioning surface 430 are arranged at intervals along a second direction. The first direction and the second direction intersect.

[0111] The adjustment protection assembly 41 includes a plurality of adjustment plates 412 and a plurality of positioning surfaces 428.

[0112] The plurality of adjustment plates 412 are classified such that the plurality of adjustment plates 412 at least includes the first adjustment plate 413 and the second adjustment plate 414.

[0113] The plurality of positioning surfaces 428 are classified such that the plurality of positioning surfaces 428 at least includes the first positioning surface 429 and the second positioning surface 430.

[0114] The first adjustment plate 413 cooperates with the first positioning surface 429, and the second adjustment plate 414 cooperates with the second positioning surface 430.

[0115] Specifically, the first adjustment plate 413 and the first positioning surface 429 are arranged at intervals along a first direction. The second adjustment plate 414 and the second positioning surface 430 are arranged at intervals along a second direction. The first direction and the second direction intersect. That is, the first direction and the second direction are different. In other words, the direction of the first adjustment plate 413 to the first positioning surface 429 is different from the direction of the second adjustment plate 414 to the second positioning surface 430. Specifically, the first direction intersects the second direction.

[0116] Specifically, the adjusting and protecting assembly 41 comprises a first adjusting plate 413, a first locating surface 429, a second adjusting plate 414 and a second locating surface 430. In the first direction, the battery device 30 is abutted between the first adjusting plate 413 and the first locating surface 429. In the second direction, the battery device 30 is abutted between the second adjusting plate 414 and the second locating surface 430.

[0117] Exemplarily, the first portion of the buffering structure 44 is connected to the side of the first adjusting plate 413 facing the first locating surface 429, and / or the second portion of the buffering structure 44 is connected to the side of the second adjusting plate 414 facing the second locating surface 430.

[0118] Wherein, the intersection of the first direction and the second direction means that the first direction and the second direction can be arranged perpendicular to each other, or the first direction and the second direction can only intersect and be arranged non-perpendicular, such as the first direction and the second direction are arranged to intersect at an acute angle, such as the first direction and the second direction are arranged to intersect at an obtuse angle. For example, the first direction and the second direction are arranged at 30°, 40°, 50°, 60°, 70°, 80°, 100°, 110°, 120°, 130°, 140°, 150°, 160° or 170°.

[0119] Therefore, the first adjusting plate 413, the first locating surface 429, the second adjusting plate 414 and the second locating surface 430 cooperate to clamp and fix the battery device 30 from two different directions, so as to increase the contact area of the adjusting and protecting assembly 41 and the battery device 30, increase the contact angle of the adjusting and protecting assembly 41 and the battery device 30, and enable the battery device 30 to be stably and reliably assembled in the battery storage device 4.

[0120] In some embodiments, as shown in Figure 3 , Figure 5 and Figure 8 , the driving part 418 comprises a motor 419, a screw rod 420 and a guide rod 421. The screw rod 420 is screwed with the adjusting plate 412. The output end of the motor 419 is connected with the screw rod 420. The motor 419 drives the screw rod 420 to rotate, so as to drive the adjusting plate 412 to move along the axial direction of the screw rod 420. The guide rod 421 penetrates the adjusting plate 412, and the guide rod 421 is gap-fitted with the adjusting plate 412.

[0121] The driving part 418 comprises a motor 419, a screw rod 420 and a guide rod 421.

[0122] The motor 419 is a device capable of converting electrical energy into mechanical energy. The motor 419 works based on the principle of electromagnetic induction. Specifically, the energized conductor is subjected to the action of Ampere force in the magnetic field to make the output end of the motor 419 produce rotary motion.

[0123] The screw rod 420 is a kind of cylinder with helical grooves cut on the outer surface.

[0124] The guide rod 421 is a rod body with a guiding function, and is used to guide the axial movement of the adjusting plate 412 along the screw rod 420.

[0125] The guide rod 421 penetrates the adjusting plate 412 and is in a clearance fit with the adjusting plate 412. The guide rod 421 has a function of guiding the movement path of the adjusting plate 412, so that the adjusting plate 412 can move stably along the axial direction of the screw rod 420. Since the guide rod 421 is in a clearance fit with the adjusting plate 412, the guide rod 421 only guides the movement track of the adjusting plate 412, and does not hinder the movement of the adjusting plate 412.

[0126] The guide rod 421 and the screw rod 420 cooperate to enable the adjusting plate 412 to move stably and orderly along the axial direction of the screw rod 420, and have the advantages of convenient assembly, high feasibility, and low production cost. If the guide rod 421 is replaced by the screw rod 420, the machining precision requirement of the driving part 418 will be increased, and the problem of the adjusting plate 412 being stuck at a certain position of the screw rod 420 due to machining errors is likely to occur.

[0127] The output end of the motor 419 is connected with the screw rod 420. When the motor 419 works, the output end of the motor 419 rotates and drives the screw rod 420 to rotate. The rotation of the screw rod 420 can drive the adjusting plate 412 which is screwed with the screw rod 420 to move along the axial direction of the screw rod 420.

[0128] Therefore, the motor 419, the screw rod 420, and the guide rod 421 cooperate to achieve the purpose of adjusting the distance between the adjusting plate 412 and the positioning surface 428. The adjusting plate 412 can move stably and reliably along the axial direction of the screw rod 420.

[0129] In other embodiments, the driving part 418 includes a cylinder and a telescopic rod. The adjusting plate 412 is connected with the telescopic rod. The cylinder drives the telescopic rod to extend or retract. The adjusting plate 412 moves relative to the positioning surface 428 under the driving of the telescopic rod, so as to achieve the purpose of adjusting the distance between the adjusting plate 412 and the positioning surface 428.

[0130] In some embodiments, as shown in Figure 3 , Figure 5 and Figure 6 , the number of screw rods 420 is multiple, the number of motors 419 is multiple, and the number of guide rods 421 is multiple. Each motor 419 is connected with one screw rod 420. One threaded hole 415 or one guide hole 416 is arranged at each corner 417 of the adjusting plate 412. The threaded hole 415 is used to cooperate with the screw rod 420, and the threaded hole 415 is screwed with the screw rod 420. The guide hole 416 cooperates with the guide rod 421. The guide rod 421 penetrates the guide hole 416, and the guide rod 421 is in a clearance fit with the guide hole 416.

[0131] The number of the screw rods 420, the motors 419 and the guide rods 421 is multiple, and each motor 419 is connected with one screw rod 420.

[0132] The adjusting plate 412 has multiple corners 417, and each corner 417 is provided with a threaded hole 415 or a guide hole 416. The threaded hole 415 is used for cooperating with the screw rod 420, and the guide hole 416 is used for cooperating with the guide rod 421.

[0133] When the corner 417 of the adjusting plate 412 is provided with the threaded hole 415, the screw rod 420 is screwed with the threaded hole 415.

[0134] When the corner 417 of the adjusting plate 412 is provided with the guide hole 416, the guide rod 421 is inserted into the guide hole 416, and there is a gap between the outer surface of the guide rod 421 and the hole wall of the guide hole 416.

[0135] In addition, since the connection positions of the screw rod 420 and the guide rod 421 with the adjusting plate 412 are located at the corners 417 of the adjusting plate 412, the volume of the clamping area 431 can be increased, so that the battery device 30 with different sizes can be effectively assembled in the clamping area 431, the probability of interference between the screw rod 420 and the guide rod 421 and the battery device 30 is reduced, and the use requirement that the adjusting and protecting assembly 41 effectively clamps and fixes the battery device 30 can be met.

[0136] Exemplarily, the number of the threaded holes 415 and the guide holes 416 is multiple, and the number of the threaded holes 415 is equal to the number of the guide holes 416. The multiple threaded holes 415 are located on the same side of the adjusting plate 412, and the multiple guide holes 416 are located on the same side of the adjusting plate 412.

[0137] Therefore, the screw rod 420 or the guide rod 421 is arranged at each corner 417 of the adjusting plate 412, so as to increase the cooperation area of the driving part 418 and the adjusting plate 412, increase the cooperation angle of the driving part 418 and the adjusting plate 412, guide the movement track of the adjusting plate 412 from multiple directions and multiple angles, and enable the adjusting plate 412 to effectively move along the axial direction of the screw rod 420.

[0138] In some embodiments, the adjusting structure 411 further comprises a mounting base 422. The adjusting plate 412 is located between the mounting base 422 and the positioning surface 428. The screw rod 420 and the guide rod 421 are located on a first side of the mounting base 422, and a part of the motor 419 is located on a second side of the mounting base 422, which is opposite to the first side of the mounting base 422 in a direction from the adjusting plate 412 to the mounting base 422. An output end of the motor 419 penetrates through the mounting base 422 and is connected with the screw rod 420. The guide rod 421 is connected with the mounting base 422. A side of the mounting base 422 away from the adjusting plate 412 is provided with a partition plate 432.

[0139] The adjusting structure 411 further comprises a mounting base 422, which is located on a side of the adjusting plate 412 away from the positioning surface 428.

[0140] The mounting base 422 is a block structure, which has high structural strength and rigidity and can effectively support the motor 419. A side of the mounting base 422 away from the adjusting plate 412 is provided with the partition plate 432, which protrudes from an outer surface of the mounting base 422. The partition plate 432 is arranged such that a gap is formed between the side of the mounting base 422 away from the adjusting plate 412 and a cavity wall of the cavity 401, so as to provide space support for the motor 419, and a part of the motor 419 can be located on the side of the mounting base 422 away from the adjusting plate 412.

[0141] For example, in a height direction of the battery storage device 4, a position of the partition plate 432 is lower than a position of the motor 419. The partition plate 432 does not hinder the assembly of the motor 419 and the mounting base 422. For example, the partition plate 432 is located at a bottom of the mounting base 422, and the motor 419 is located at a top of the mounting base 422. For example, the partition plate 432 is located at a middle of the mounting base 422, and the motor 419 is located at a top of the mounting base 422.

[0142] The guide rod 421 and the screw rod 420 are located on the same side of the mounting base 422, and the guide rod 421 is connected with the mounting base 422. The mounting base 422 supports and fixes the guide rod 421. The mounting base 422 and the motor 419 cooperate to provide structural support for the axial movement of the adjusting plate 412 along the screw rod 420.

[0143] The mounting base 422 serves as a mounting carrier of the motor 419 and supports and fixes the motor 419. A part of the motor 419 is located on a side of the mounting base 422 away from the adjusting plate 412, which can reduce the space occupancy of the motor 419 on the clamping area 431, increase the volume of the clamping area 431, and provide structural support for the battery storage device 4 to store battery devices 30 of different sizes without changing the size of the battery storage device 4.

[0144] In some embodiments, as shown in FIG. 4A, the adjusting structure 411 further comprises a positioning plate 425. The positioning plate 425 is arranged opposite to the adjusting plate 412 and spaced apart from the adjusting plate 412. The side end face of the positioning plate 425 facing the adjusting plate 412 is a positioning face 428. The screw rod 420 and the guide rod 421 are both located on the circumferential side of the positioning face 428. Figure 1 , Figure 3 , Figure 5 and Figure 6 In the case that the cavity wall of the cavity 401 has the positioning face 428, the guide rod 421 is fixedly connected with the shell assembly 40. That is, the guide rod 421 is connected with the shell assembly 40, but the guide rod 421 cannot move relative to the shell assembly 40. The guide rod 421 can be welded with the shell assembly 40, or the guide rod 421 can be locked with the shell assembly 40 by fasteners, and the like, which are not listed one by one. The shell assembly 40, the adjusting plate 412 and the mounting seat 422 cooperate to effectively limit the guide rod 421.

[0145] In the case that the cavity wall of the cavity 401 has the positioning face 428, the guide rod 421 is fixedly connected with the shell assembly 40. That is, the guide rod 421 is connected with the shell assembly 40, but the guide rod 421 cannot move relative to the shell assembly 40. The guide rod 421 can be welded with the shell assembly 40, or the guide rod 421 can be locked with the shell assembly 40 by fasteners, and the like, which are not listed one by one. The shell assembly 40, the adjusting plate 412 and the mounting seat 422 cooperate to effectively limit the guide rod 421.

[0146] In the case that the cavity wall of the cavity 401 has the positioning face 428, the screw rod 420 is rotatably connected with the shell assembly 40. The screw rod 420 can move relative to the shell assembly 40. The shell assembly 40 not only supports the screw rod 420, but also does not prevent the screw rod 420 from rotating, so that the screw rod 420 can rotate under the drive of the motor 419, and provides structural support for the axial movement of the adjusting plate 412 along the screw rod 420.

[0147] Therefore, the shell assembly 40 not only has the function of forming the positioning face 428, but also has the function of supporting the screw rod 420 and the guide rod 421, which can meet the use requirement of effectively adjusting the distance between the adjusting plate 412 and the positioning face 428.

[0148] In the case that the adjusting structure 411 has the positioning face 428, the adjusting structure 411 further comprises the positioning plate 425. The side end face of the positioning plate 425 facing the adjusting plate 412 forms the positioning face 428. That is, the adjusting plate 412 and the positioning plate 425 of the adjusting structure 411 enclose a clamping area 431. The screw rod 420 and the guide rod 421 are both located on the circumferential side of the positioning face 428. That is, the screw rod 420 is located on the circumferential side of the positioning plate 425, and the guide rod 421 is also located on the circumferential side of the positioning plate 425. When the battery device 30 is clamped, one end of the battery device 30 abuts against the positioning face 428, and the guide rod 421 and the screw rod 420 are both located on the circumferential side of the battery device 30, so that the guide rod 421 and the screw rod 420 do not interfere with the battery device 30.

[0149] Therefore, the positioning plate 425, the guide rod 421 and the screw rod 420 cooperate to meet the use requirement of effectively fixing the battery device 30, and the guide rod 421 and the screw rod 420 do not interfere with the battery device 30, which is beneficial to the disassembly and assembly of the battery device 30.

[0150] In some embodiments, as shown in FIG. 4A and FIG. 4B, the adjusting structure 411 has a positioning surface 428, and the adjusting structure 411 further includes a top plate 423. Figure 3 Figure 5 As shown in FIG. 4A and FIG. 4B, when the adjusting structure 411 has the positioning surface 428, the adjusting structure 411 further includes the top plate 423. The positioning plate 425 is located between the top plate 423 and the adjusting plate 412, and the positioning plate 425 is connected with the cavity wall of the cavity 401 through the top plate 423. The outer peripheral wall 424 of the top plate protrudes from the outer peripheral wall 426 of the positioning plate. The guide rod 421 is fixedly connected with the part of the top plate 423 located on the side of the positioning plate 425. The screw rod 420 is rotatably connected with the part of the top plate 423 located on the side of the positioning plate 425.

[0151] When the adjusting structure 411 has the positioning surface 428, the adjusting structure 411 further includes the top plate 423, that is, the adjusting structure 411 includes the adjusting plate 412, the driving part 418, the positioning plate 425 and the top plate 423. The positioning surface 428 of the positioning plate 425 is used to abut against the battery device 30.

[0152] The outer peripheral wall 424 of the top plate protrudes from the outer peripheral wall 426 of the positioning plate, that is, the positioning plate 425 and the top plate 423 are respectively cut along the direction perpendicular to the positioning plate 425 to the top plate 423, and the cross-sectional area of the positioning plate 425 is smaller than the cross-sectional area of the top plate 423.

[0153] The guide rod 421 is fixedly connected with the top plate 423. That is, the guide rod 421 is connected with the top plate 423, but the guide rod 421 cannot move relative to the top plate 423. The guide rod 421 can be welded with the top plate 423, or the guide rod 421 can be locked with the top plate 423 through a fastener, and the like, which are not listed one by one. The top plate 423, the adjusting plate 412 and the mounting seat 422 cooperate to effectively limit the guide rod 421.

[0154] The screw rod 420 is rotatably connected with the top plate 423. The screw rod 420 can move relative to the top plate 423. The top plate 423 not only supports the screw rod 420, but also does not prevent the screw rod 420 from rotating, so that the screw rod 420 can rotate under the driving of the motor 419, and provides structural support for the axial movement of the adjusting plate 412 along the screw rod 420.

[0155] ​Therefore, the top plate 423 not only has the functions of connecting the cavity wall of the cavity 401 and the positioning plate 425, but also has the functions of mounting the screw rod 420 and the guide rod 421. Meanwhile, the guide rod 421 is fixedly connected with the part of the top plate 423 located on the side of the positioning plate 425, and the screw rod 420 is rotatably connected with the part of the top plate 423 located on the side of the positioning plate 425. That is, the screw rod 420 and the guide rod 421 are both located on the side of the positioning plate 425, and when the battery device 30 is clamped, one end of the battery device 30 abuts against the positioning plate 425, and the guide rod 421 and the screw rod 420 are both located on the side of the battery device 30, so that the guide rod 421 and the screw rod 420 do not interfere with the battery device 30, and the disassembly and assembly of the battery device 30 are facilitated.

[0156] In some embodiments, as shown in Figs. 4A and 4B, the side of the adjusting plate 412 facing the positioning surface 428 is connected with the buffer structure 44, and the buffer structure 44 includes an elastic member 442 and a pressing plate 443. Figure 3 、 Figure 6 、 Figure 7 and Figure 8 In the case that the side of the adjusting plate 412 facing the positioning surface 428 is connected with the buffer structure 44, the buffer structure 44 includes an elastic member 442 and a pressing plate 443. The elastic member 442 is located between the pressing plate 443 and the adjusting plate 412, and is connected with the pressing plate 443 and the adjusting plate 412. The side end face of the pressing plate 443 away from the elastic member 442 is a contact surface 441.

[0157] In the case that the side of the adjusting plate 412 facing the positioning surface 428 is connected with the buffer structure 44, the buffer structure 44 includes an elastic member 442 and a pressing plate 443. The elastic member 442 is connected between the adjusting plate 412 and the pressing plate 443, and the pressing plate 443 is located between the adjusting plate 412 and the positioning surface 428. When the battery storage device 4 is subjected to a mechanical impact, the pressing plate 443 will move in the direction away from the positioning surface 428 under the action of the impact force to extrude the elastic member 442, so as to absorb or dissipate the energy of the external force impact, thereby slowing down the impact force transmitted to the battery device 30, so as to reduce the probability of deformation of the battery device 30. When the mechanical impact force is reduced or even the external force acting on the battery storage device 4 is removed, the elastic member 442 resets and drives the pressing plate 443 to move in the direction of the positioning surface 428 to effectively fix the battery device 30.

[0158] It can be understood that the side end face of the pressing plate 443 away from the elastic member 442 forms the contact surface 441, which can increase the contact area of the pressing plate 443 and the battery device 30, so that the force at different positions of the battery device 30 is more balanced, and the probability of local deformation of the battery device 30 caused by excessive local force of the battery device 30 is reduced.

[0159] Exemplarily, the elastic member 442 includes a spring, a gas pressure rod, a hydraulic damping member, etc., which are not listed one by one here.

[0160] Therefore, when the adjusting plate 412 is connected to the buffer structure 44 on the side facing the positioning surface 428, the buffer structure 44 includes an elastic element 442 and a pressure plate 443. While effectively fixing the battery device 30, it can effectively reduce the impact force transmitted to the battery device 30, effectively protect the battery device 30, and also has the advantages of simple structure and easy disassembly and assembly.

[0161] In some embodiments, such as Figure 3 , Figure 6 , Figure 7 and Figure 8 As shown, when the cavity wall of cavity 401 is connected to buffer structure 44, buffer structure 44 includes elastic seat 444. Elastic seat 444 is located between adjustment plate 412 and positioning surface 428. The end face of the portion of elastic seat 444 located within clamping area 431 is contact surface 441.

[0162] One end face of the elastic seat 444 can form a contact surface 441, and the elastic seat 444 can contact and abut against the battery device 30. Specifically, when the battery device 30 is installed in the battery storage device 4, the contact surface 441 of the portion of the elastic seat 444 located in the clamping area 431 contacts and abuts against the battery device 30.

[0163] When the battery storage device 4 is subjected to mechanical impact, the elastic seat 444 is squeezed and deformed under the impact force, absorbing or dissipating the energy of the external impact, thereby reducing the impact force transmitted to the battery device 30 and reducing the probability of deformation of the battery device 30. When the mechanical impact force is reduced or even removed from the external force acting on the battery storage device 4, the elastic seat 444 recovers its deformation and drives the battery device 30 to reset, effectively fixing the battery device 30. It also has the advantages of simple structure and easy assembly, effectively reducing the impact force transmitted to the battery device 30 and effectively protecting the battery device 30.

[0164] Therefore, when the cavity wall of cavity 401 is connected to buffer structure 44, buffer structure 44 includes elastic seat 444, which is located between adjustment plate 412 and positioning surface 428. It can effectively reduce the impact force transmitted to battery device 30, effectively protect battery device 30, and also has the advantages of simple structure and easy assembly.

[0165] For example, along the height direction of the battery storage device 4, the battery device 30 is located above the elastic seat 444, which serves to support the battery device 30. The contact surface 441 of the elastic seat 444 can effectively contact and abut against the battery device 30, thereby increasing the sensitivity of the elastic seat 444 to deformation under external impact and providing structural support for effectively mitigating the impact force transmitted to the battery device 30.

[0166] For example, along the direction perpendicular to the height of the battery storage device 4, the battery device 30 is located on the side of the elastic seat 444, and the contact surface 441 of the elastic seat 444 can effectively contact and abut against the battery device 30, providing structural support for effectively mitigating the impact force transmitted to the battery device 30.

[0167] For example, there are multiple elastic seats 444, including a first elastic seat and a second elastic seat. Along the height direction of the battery storage device 4, the battery device 30 is located above the first elastic seat, which supports the battery device 30. The contact surface 441 of the first elastic seat can effectively contact and abut against the battery device 30, increasing the sensitivity of the first elastic seat to deformation under external impact and providing structural support for effectively mitigating the impact force transmitted to the battery device 30. Along the direction perpendicular to the height of the battery storage device 4, the battery device 30 is located on the side of the second elastic seat, and the contact surface 441 of the second elastic seat can effectively contact and abut against the battery device 30, providing structural support for effectively mitigating the impact force transmitted to the battery device 30.

[0168] For example, the resilient seat 444 includes any one or a combination of the following: a rubber seat, a silicone seat, and a spring seat.

[0169] In some embodiments, such as Figure 8 As shown, the battery storage device 4 also includes a sealing layer 46. The sealing layer 46 covers at least a portion of the bottom wall 404 of the cavity, at least a portion of the side wall 403 of the cavity, and the junction of the bottom wall and the side wall.

[0170] The battery storage device 4 also includes a sealing layer 46. The sealing layer 46 covers at least a portion of the bottom wall 404 of the cavity, at least a portion of the side wall 403 of the cavity, and the junction of the bottom wall and the side wall.

[0171] For example, the sealing layer 46 includes any one or a combination of the following: a ceramic composite coating and a liquid oxide-like composite coating. For example, the sealing layer 46 is applied to the cavity wall of the cavity 401 by coating. For example, the sealing layer 46 is applied to the cavity wall of the cavity 401 by adhesive bonding.

[0172] The sealing layer 46 serves to seal the cavity wall of the cavity 401. In this way, even if the battery device 30 installed in the battery storage device 4 leaks, the liquid will not leak into the external environment due to the sealing layer 46. That is, the liquid will be retained in the cavity 401, thus reducing the probability of liquid leakage and pollution of the external environment.

[0173] Due to the effect of gravity, even if the battery device 30 leaks, the liquid will accumulate at the bottom of the cavity 401, so that the sealing layer 46 covers at least part of the cavity bottom wall 404 of the cavity, at least part of the cavity side wall 403 of the cavity, and the junction of the cavity bottom wall 404 and the cavity side wall 403 of the cavity, while effectively sealing the cavity 401, reducing the material input of the sealing layer 46, and helping to reduce the production cost of the product.

[0174] In other embodiments, the sealing layer 46 covers all the cavity walls of the cavity 401.

[0175] In some embodiments, as shown in Figure 8 The cavity bottom wall 404 of the cavity is provided with a flow guide groove 402.

[0176] The cavity bottom wall 404 of the cavity is provided with a flow guide groove 402.

[0177] Exemplarily, part of the cavity wall of the cavity 401 is recessed to form the flow guide groove 402.

[0178] The flow guide groove 402 has the functions of guiding flow and collecting leaked liquid. In this way, even if the battery device 30 leaks, the liquid flowing to the flow guide groove 402 will be collected in the flow guide groove 402 along the groove wall of the flow guide groove 402. The flow guide groove 402 can direct the corrosive electrolyte to flow to a specific safe area, reducing the probability of short circuit or corrosion of the battery device 30 caused by liquid accumulation.

[0179] In some embodiments, the number of flow guide grooves 402 is multiple. The cavity 401 has a first side and a second side. Part of the multiple flow guide grooves 402 is located on the first side of the cavity 401. Another part of the multiple flow guide grooves 402 is located on the second side of the cavity 401.

[0180] The number of flow guide grooves 402 is multiple. Part of the multiple flow guide grooves 402 is located on the first side of the cavity 401. Another part of the multiple flow guide grooves 402 is located on the second side of the cavity 401.

[0181] Specifically, the arrangement positions of the multiple flow guide grooves 402 are divided so that the multiple flow guide grooves 402 include a first flow guide groove and a second flow guide groove, the first flow guide groove is located on the first side of the cavity 401, and the second flow guide groove is located on the second side of the cavity 401. The first flow guide groove and the second flow guide groove are located on different sides of the cavity 401.

[0182] By reasonably setting the arrangement positions of the multiple flow guide grooves 402, the leaked liquid can be guided and collected from multiple directions and multiple positions, the corrosive electrolyte can be directed to flow to a specific safe area, and the probability of short circuit or corrosion of the battery device 30 caused by liquid accumulation can be reduced.

[0183] Exemplarily, the first side of the cavity 401 and the second side of the cavity 401 are oppositely arranged. Alternatively, the first side of the cavity 401 and the second side of the cavity 401 are adjacently arranged.

[0184] In some other embodiments, the number of the flow guide grooves 402 is one.

[0185] In some embodiments, as shown in Figure 3 and Figure 5 The positioning face 428 is provided with a positioning part 427. The positioning part 427 comprises a positioning recess, or the positioning part 427 comprises a positioning protrusion.

[0186] The positioning face 428 is provided with a positioning part 427. The positioning part 427 comprises a positioning recess, or the positioning part 427 comprises a positioning protrusion.

[0187] The positioning face 428 is provided with a positioning recess. It can be understood that a part of the positioning face 428 is recessed in a direction away from the adjusting plate 412 to form the positioning recess.

[0188] The positioning face 428 is provided with a positioning protrusion. It can be understood that a part of the positioning face 428 is protruded in a direction towards the adjusting plate 412 to form the positioning protrusion.

[0189] In the case that the side end face of the battery device 30 is provided with a clamping groove, the positioning part 427 comprises a positioning protrusion. After the battery device 30 is assembled in the battery storage device 4, the positioning protrusion is clamped in the clamping groove, and the positioning protrusion and the clamping groove are matched to limit the displacement of the battery device 30 relative to the positioning face 428, so that the battery device 30 can be stably assembled with the positioning face 428.

[0190] In the case that the side end face of the battery device 30 is provided with a protruding structure, the positioning part 427 comprises a positioning recess. After the battery device 30 is assembled in the battery storage device 4, the protruding structure is clamped in the positioning recess, and the protruding structure and the positioning recess are matched to limit the displacement of the battery device 30 relative to the positioning face 428, which can reduce the difficulty of fixing the battery device 30 by the adjusting and protecting assembly 41 subsequently, so that the battery device 30 can be stably assembled with the positioning face 428.

[0191] In some embodiments, as shown in Figure 2 The battery storage device 4 further comprises a thermometer 47. The thermometer 47 is arranged on the shell assembly 40. The thermometer 47 is used to detect and display the temperature of the cavity 401.

[0192] The battery storage device 4 further comprises a thermometer 47.

[0193] The thermometer 47 is arranged on the shell assembly 40, and the shell assembly 40 serves as a mounting carrier of the thermometer 47 and has the function of mounting and fixing the thermometer 47.

[0194] The thermometer 47 can detect the temperature of the cavity 401 and display the temperature of the cavity 401. In this way, the operator can learn the temperature in the cavity 401 in time through the thermometer 47 and learn the storage condition of the battery device 30 in time. The temperature of the battery device 30 can be monitored in real time through the thermometer 47, and the risk of thermal runaway can be prevented. It can be understood that the battery device 30 will catch fire and explode when the temperature is too high. By arranging the thermometer 47, the reliability of the battery storage device 4 can be improved, and the risk of thermal runaway can be reduced.

[0195] Exemplarily, the thermometer 47 includes a mercury thermometer and / or an electronic thermometer.

[0196] Exemplarily, the number of the thermometer 47 is one.

[0197] Exemplarily, the number of the thermometer 47 is multiple. The multiple thermometers 47 are arranged on the same side of the shell assembly 40. Alternatively, the multiple thermometers 47 are arranged on at least two sides of the shell assembly 40, so that the operator can learn the temperature of the cavity 401 from the thermometers 47 at different positions.

[0198] Exemplarily, the thermometer 47 is arranged on the top of the shell assembly 40, so as to facilitate the operator to monitor the temperature of the thermometer 47.

[0199] In some embodiments, as shown in Figure 2 The shell assembly 40 is also provided with a vent 406. The vent 406 is in communication with the cavity 401.

[0200] The shell assembly 40 is provided with a vent 406, and the vent 406 is in communication with the cavity 401.

[0201] Exemplarily, the battery storage device 4 further includes a one-way valve arranged at the vent 406, and the one-way valve can seal the vent 406. The one-way valve is open in the direction from the cavity 401 to the outside of the shell assembly 40. When the battery device 30 stored in the battery storage device 4 is in thermal runaway and rapidly releases internal high-pressure gas and heat, the gas flows out of the battery storage device 4 through the one-way valve.

[0202] Exemplarily, the vent 406 is arranged on the top of the shell assembly 40, so as to facilitate the rapid release of gas.

[0203] When the battery device 30 stored in the battery storage device 4 is in thermal runaway and releases internal high-pressure gas and heat rapidly, the gas can be discharged out of the battery storage device 4 through the explosion vent 406, achieving the purpose of rapid pressure release, reducing the probability of explosion due to sudden increase of pressure in the cavity 401, and improving the reliability of use of the battery storage device 4.

[0204] In some embodiments, as shown in Figure 2 At least one reinforcing rib 405 is arranged on the shell assembly 40.

[0205] At least one reinforcing rib 405 is arranged on the shell assembly 40. The reinforcing rib 405 includes any one or a combination of the following: a rib strip, a rib block, and a rib plate.

[0206] Exemplarily, the plurality of reinforcing ribs 405 are located on the same side of the shell assembly 40.

[0207] Exemplarily, the plurality of reinforcing ribs 405 are distributed on at least two sides of the shell assembly 40.

[0208] The reinforcing rib 405 has the effect of enhancing the structural strength and the structural rigidity of the shell assembly 40, so as to enhance the deformation resistance of the shell assembly 40. Meanwhile, the reinforcing rib 405 can also enhance the load-bearing capacity of the shell assembly 40, so that the battery device 30 with a relatively large weight can be placed in the battery storage device 4, or a relatively large number of battery devices 30 can be placed in the battery storage device 4.

[0209] In addition, by arranging the reinforcing rib 405, the strength can be improved without increasing the wall thickness of the shell assembly 40, which is conducive to reducing the material usage of the shell assembly 40, reducing the weight of the shell assembly 40, and reducing the production cost of the battery storage device 4. The structural arrangement of the reinforcing rib 405 can also increase the surface friction of the shell assembly 40, so that the battery storage device 4 will not slip when being transported.

[0210] In some embodiments, as shown in Figure 2 The shell assembly 40 includes a box body 407 and a cover body 408. The cover body 408 is arranged on the box body 407 in a detachable manner. The box body 407 and the cover body 408 enclose the cavity 401.

[0211] The shell assembly 40 includes a box body 407 and a cover body 408.

[0212] The cover body 408 is detachably connected with the box body 407, that is, the cover body 408 can be arranged on the box body 407 to seal the box body 407, and the box body 407 and the cover body 408 enclose the cavity 401. The cover body 408 can also be removed from the box body 407.

[0213] By setting the structure of the shell assembly 40, the use requirement of installing the battery device 30 in the battery storage device 4 and taking out the battery device 30 from the battery storage device 4 can be met.

[0214] In some embodiments, as shown in Figure 2 The battery storage device 4 further comprises a first connecting part 48 and a second connecting part 49. The first connecting part 48 is arranged on the box body 407. The second connecting part 49 is arranged on the cover body 408. The box body 407 and the cover body 408 are detachably connected through the first connecting part 48 and the second connecting part 49. The first connecting part 48 and the second connecting part 49 are snap-fit connected, and / or the first connecting part 48 and the second connecting part 49 are locked connected, and / or the first connecting part 48 and the second connecting part 49 are magnetically attracted connected.

[0215] The battery storage device 4 further comprises a first connecting part 48 and a second connecting part 49.

[0216] In the case of snap-fit connection of the first connecting part 48 and the second connecting part 49, the box body 407 and the cover body 408 are snap-fit connected through the first connecting part 48 and the second connecting part 49. When it is needed to separate the box body 407 and the cover body 408, only an external force is needed to overcome the snap-fit force between the first connecting part 48 and the second connecting part 49, so that the separation of the box body 407 and the cover body 408 can be realized.

[0217] In the case of locked connection of the first connecting part 48 and the second connecting part 49, the first connecting part 48 and the second connecting part 49 are locked connected through fasteners, including bolts, screws or rivets.

[0227] As shown in Figure 8As shown, some other embodiments of the battery assembly 3 provided by the present application include the battery device 30 and the battery storage device 4 of any of the above embodiments. The battery device 30 includes battery cells. The battery device 30 is detachably arranged in the cavity 401. In the case that the side of the adjusting plate 412 facing the positioning surface 428 is connected with the buffer structure 44, the battery device 30 is abutted between the contact surface 441 and the positioning surface 428. In the case that the cavity wall of the cavity 401 is connected with the buffer structure 44, the battery device 30 is abutted between the adjusting plate 412 and the positioning surface 428, and the contact surface 441 is abutted with the battery device 30. In the case that the side of the adjusting plate 412 facing the positioning surface 428 and the cavity wall of the cavity 401 are both connected with the buffer structure 44, the contact surface 441 includes a first sub-surface 445 and a second sub-surface 446, the part of the buffer structure 44 connected with the adjusting plate 412 has the first sub-surface 445, the part of the buffer structure 44 connected with the cavity wall of the cavity 401 has the second sub-surface 446, the battery device 30 is abutted between the first sub-surface 445 and the positioning surface 428, and the second sub-surface 446 is abutted with the battery device 30.

[0229] The battery assembly 3 includes the battery device 30 and the battery storage device 4. The battery device 30 includes battery cells.

[0230] In the case that the side of the adjusting plate 412 facing the positioning surface 428 is connected with the buffer structure 44, the contact surface 441 of the buffer structure 44 is located in the clamping area 431, and the battery device 30 is located between the contact surface 441 of the buffer structure 44 and the positioning surface 428. When the driving part 418 drives the adjusting plate 412 to move relative to the shell assembly 40, the distance between the adjusting plate 412 and the positioning surface 428 can be adjusted, and thus the distance between the contact surface 441 and the positioning surface 428 can be adjusted, so that the battery device 30 is abutted between the contact surface 441 and the positioning surface 428. When the battery storage device 4 is subjected to mechanical impact, the contact surface 441 of the buffer structure 44 will move relative to the positioning surface 428 under the action of the impact force, so as to absorb or dissipate the energy of the external force impact, thereby slowing down the impact force transmitted to the battery device 30, so as to reduce the probability of deformation of the battery device 30.

[0231] When the cavity wall of cavity 401 is connected to buffer structure 44, the contact surface 441 of buffer structure 44 is located within clamping area 431, and battery device 30 is located between adjustment plate 412 and positioning surface 428. When drive unit 418 drives adjustment plate 412 to move relative to shell assembly 40, the distance between adjustment plate 412 and positioning surface 428 can be adjusted to effectively clamp and fix battery device 30 through adjustment plate 412 and positioning surface 428, so that battery device 30 abuts between adjustment plate 412 and positioning surface 428, and since contact surface 441 is located within clamping area 431, contact surface 441 can contact and abut with battery device 30. When battery storage device 4 is subjected to mechanical impact, contact surface 441 of buffer structure 44 will move relative to shell assembly 40 under the action of impact force to absorb or dissipate the energy of external impact, thereby reducing the impact force transmitted to battery device 30 and reducing the probability of deformation of battery device 30.

[0232] With the side of the adjusting plate 412 facing the positioning surface 428 and the cavity wall of the cavity 401 both connected to the buffer structure 44, the contact surface 441 of the buffer structure 44 is located within the clamping area 431.

The portion of the buffer structure 44 connected to the adjusting plate 412 has the first sub-surface 445, and the portion of the buffer structure 44 connected to the cavity wall of the cavity 401 has the second sub-surface 446. When the driving unit 418 drives the adjusting plate 412 to move relative to the housing assembly 40, the distance between the adjusting plate 412 and the positioning surface 428 can be adjusted, thereby adjusting the distance between the first sub-surface 445 and the positioning surface 428, so as to effectively clamp and fix the battery device 30 through the first sub-surface 445 and the positioning surface 428. At the same time, the second sub-surface 446 contacts and abuts against the battery device 30. When the battery storage device 4 is subjected to mechanical impact, the first sub-surface 445 will move relative to the positioning surface 428 under the action of the impact force, and the second sub-surface 446 will move relative to the shell assembly 40 under the action of the impact force. The first sub-surface 445 and the second sub-surface 446 cooperate to absorb or dissipate the energy of the external impact from multiple positions and multiple directions, thereby reducing the impact force transmitted to the battery device 30 and reducing the probability of deformation of the battery device 30.
