[0003] The battery case generally includes a first shell and a second shell, and the second shell is connected to the opening of the first shell to seal the first shell. In the related art, the second shell is fixed to the first shell by bolts, and repeated screwing is required during installation and disassembly, which makes the operation inconvenient. Utility Model Content

[0004] The purpose of the present application is to provide a battery box, a battery and an electrical device, aiming to solve the technical problem of poor convenience in the installation and disassembly process of the battery box.

[0005] In a first aspect, the present application provides a battery box, comprising:

[0006] A first shell having an inner cavity, wherein an opening communicating with the inner cavity is formed on the first shell;

[0007] A second shell is connected to the first shell and covers the opening;

[0008] A structural member connected to the first shell;

[0009] The connecting component is arranged between the second shell and the structural component to enable the second shell and the structural component to be adsorbed and connected.

[0010] In this example, a connecting component capable of generating an adsorption force is provided, and the connecting component is configured on the second shell and a structural component connected to the first shell, and the second shell is connected and fixed to the first shell by adsorption. During the adsorption connection, the adsorption and fixation can be achieved only by abutting and squeezing the connecting component against the second shell or the connecting component. During disassembly, separation can be achieved by overcoming the adsorption force through external force, and there is no need to configure components such as bolt assemblies, and of course there is no need to perform screwing operations, thereby making the assembly and disassembly of the first shell and the second shell faster and more convenient, saving time and effort, and helping to improve the work efficiency during assembly and disassembly of the battery case.

[0011] In one embodiment, the connecting component includes a connecting body and a first suction cup connected to the connecting body, the connecting body is connected to the structural member, and the first suction cup is adsorbed and connected to the second shell.

[0012] In this example, by configuring the first suction cup, the first suction cup and the second shell are adsorbed and connected, which can achieve quick adsorption connection between the second shell and the first shell, and also make it unnecessary to open holes in the second shell, and no longer need to open holes and connect bolts. After reducing the number of holes on the second shell, the airtightness of the accommodating space after the second shell and the first shell are assembled can be increased, reducing the risk of airtight failure of the battery case.

[0013] In one embodiment, the connector is detachably or fixedly connected to the structural member.

[0014] In this example, the connecting component is not easily separated from the structural component and lost, thereby ensuring the reliability of the connection between the connecting component, the structural component and the first shell.

[0015] In one embodiment, the connecting component includes a connecting body and a first suction cup connected to the connecting body, the connecting body is connected to the second shell, and the first suction cup is adsorbed and connected to the structural member.

[0016] In this example, the first suction cup is adsorbed and connected to the structural member, so that the second shell and the first shell can be quickly adsorbed and connected, which is beneficial to improving the convenience of connecting and disassembling the second shell and the first shell and improving work efficiency.

[0017] In one embodiment, the connector is detachably or fixedly connected to the second shell.

[0018] In this example, the connecting component is not easily separated from the second shell and lost, thereby ensuring the reliability of the connection between the connecting component and the second shell. In addition, by welding or one-piece molding, there is no need to open holes in the second shell. After reducing the number of holes on the second shell, the airtightness of the accommodating space after the second shell and the first shell are assembled can be increased, thereby reducing the risk of airtight failure of the battery case.

[0019] In one embodiment, a connecting head is formed on the connecting body, and the connecting head includes a plurality of ring tooth structures protruding from the surface of the connecting head, and the plurality of ring tooth structures are arranged at intervals along a preset direction on the connecting body, or the plurality of ring tooth structures are transitionally connected along a preset direction on the connecting body to form a spiral shape; the connecting head is connected to the structural member or the second shell through the ring tooth structure.

[0020] In this example, the end of the connector away from the first suction cup is detachably connected to the structural member or the second shell. The design of the ring tooth structure enables the connector to be detachably connected by screwing, making the connection more reliable.

[0021] In one embodiment, the first suction cup is extended outward from a connection position with the connecting body toward a direction away from the connecting body, and a first adsorption groove is formed at the extended end.

[0022] In this example, the adsorption force is generated by exhausting air from the first adsorption groove to generate negative pressure. The first suction cup can be used manually, which is convenient and flexible to use and is conducive to improving work efficiency.

[0023] In one embodiment, the connecting component further includes a second suction cup, the second suction cup is connected to the connecting body, and the connecting body is adsorbed to the structural member through the second suction cup.

[0024] In this example, the connecting component is an independent component that is independent of the first shell body, the second shell body and the structural parts. The adsorption connection between the first shell body and the second shell body is achieved by adsorbing the second shell body with the first suction cup and adsorbing the structural parts on the first shell body with the second suction cup. When installing and disassembling the battery box, vacuum adsorption can be achieved by squeezing the first suction cup and the second suction cup, which makes the operation more convenient and helps to improve work efficiency.

[0025] In one embodiment, the second suction cup is extended outward from a connection position with the connecting body toward a direction away from the connecting body, and a second suction groove is formed at the extended end.

[0026] In this example, the second suction cup expands outward to form a cone and forms a second adsorption groove. The adsorption force is generated by exhausting air from the second adsorption groove to generate negative pressure. The second suction cup can be used manually, which is convenient and flexible to use and helps to improve work efficiency.

[0027] In one embodiment, the connecting body is configured to extend in a columnar shape, and the first suction cup is connected to an extending end of the connecting body.

[0028] In this example, a columnar connector is used, and the first suction cup and the second suction cup are respectively arranged at its two ends, or the first suction cup and the connecting head are respectively arranged at the two ends of the connector. Then, the connecting component can form a stable support between the second shell and the structural member, which is beneficial to improving the stability of the support. In addition, the overall structure of the connecting component is simpler, which is beneficial to improving the convenience of processing.

[0029] In one embodiment, a plurality of the connecting components are provided, and the plurality of connecting components are arranged at intervals between the second shell and the structural component.

[0030] In this example, when the second shell is connected to the first shell, multiple connecting components can provide adsorption force, thereby improving the connection strength and firmness, making the connection between the second shell and the first shell more firm.

[0031] In one of the embodiments, the battery box further includes a pipe component and a control valve, a channel is formed inside the pipe component, and the channel is connected to both the first suction cup and the control valve.

[0032] In this example, by configuring a pipe component, the channel inside the pipe component is connected to the first suction cup, so that the purpose of generating negative pressure in the first adsorption groove can be achieved directly by controlling the pressure in the channel. The pipe component can extend to a position away from the first suction cup, combined with an external vacuum component, etc., so as to achieve the purpose of long-distance adsorption control of the first suction cup.

[0033] In one of the embodiments, the battery box further includes a pipe component and a control valve, a channel is formed inside the pipe component, and the channel is connected to the first suction cup, the second suction cup and the control valve.

[0034] In this example, by configuring a pipe component, the channel inside the pipe component is connected to the first suction cup and the second suction cup, so that the purpose of generating negative pressure in the first adsorption groove and the second adsorption groove can be achieved directly by controlling the pressure in the channel. The pipe component can extend to a position away from the first suction cup and the second suction cup, and combined with an external vacuum component, etc., so as to achieve the purpose of long-distance adsorption control of the first suction cup and the second suction cup.

[0035] In one embodiment, the control valve is mounted on the first housing or the second housing.

[0036] In this example, the air suction component works and can control the adsorption force of the first suction cup and the second suction cup at the position of the control valve outside the first shell and the second shell, thereby improving the convenience of operation.

[0037] In one of the embodiments, the battery box further includes an air extraction component, and the air extraction component is connected to the channel.

[0038] In this example, by configuring an air suction component, automatic adsorption can be performed between the first suction cup and the second shell, as well as between the second suction cup and the structural member; in addition, when air leakage occurs at the positions of the first suction cup and the second suction cup, resulting in a decrease in the adsorption force, the air suction component can be operated to further evacuate the first suction cup and the second suction cup, thereby increasing the adsorption force at the positions of the first suction cup and the second suction cup and improving the connection strength and connection reliability.

[0039] In one embodiment, there are multiple connecting components, and the multiple connecting components are arranged at intervals between the second shell and the structural member; there are multiple pipe components, and the multiple connecting components are connected by the pipe components so that the channels in each pipe component are connected.

[0040] In this example, multiple connecting components are connected between the second shell and the first shell at the same time, which can enhance the connection strength between the second shell and the first shell. In addition, when the vacuum component vacuums the channel in the pipeline component, the first suction cups and the second suction cups on all connecting components can simultaneously generate negative pressure, and then generate adsorption force at the same time. The adsorption effect of all connecting components on the first shell and the second shell can be completed in one operation, and the convenience is improved.

[0041] In one embodiment, the pipeline component includes a connecting pipe and a sleeve, one end of the connecting pipe is connected to the connector, the other end of the connecting pipe is detachably connected to the sleeve, and the channel is formed in the connecting pipe and the sleeve.

[0042] In this example, the pipeline component is in the form of a combination of a connecting pipe and a sleeve, so that the sleeve and the connecting component in the pipeline component can be installed and disassembled independently, making the overall structure formed by the pipeline component and the connecting component more convenient and flexible during disassembly and installation.

[0043] In one embodiment, the sleeve is sleeved on the other end of the connecting pipe; the pipeline component further includes a sealing member connected between the sleeve and the connecting pipe.

[0044] In this example, a seal is provided at the connection position between the sleeve and the connecting pipe to improve the sealing performance of the connection position between the sleeve and the connecting pipe, reduce the possibility of air leakage, and thereby ensure the pressure state in the channel, the first adsorption tank and the second adsorption tank, and ensure the reliability of the connection between the connecting component and the first shell and the second shell.

[0045] In one embodiment, there are a plurality of connecting components, which are arranged at intervals between the second shell and the structural member; there are a plurality of pipe components, which are connected by the sleeves so that the channels in the sleeves are connected.

[0046] In this example, the connecting pipe is connected to the connecting body, and the sleeve and the connecting pipe can be detachably connected, so the sleeve and the connecting component can be independently installed and disassembled, and the sleeve extends from the connection position with the connecting pipe in a direction away from the connecting pipe to communicate with another sleeve, so that the sleeves are mutually connected and communicated with each other, so that the various connecting components can be connected and form a whole, and the overall structure formed by the pipeline component and the connecting component is more convenient and flexible during disassembly and installation.

[0047] In one of the embodiments, the battery box further includes a monitoring component, which is connected to the connecting component to monitor the adsorption pressure between the second shell and the structural member.

[0048] In this example, the monitoring component can monitor the pressure values ​​of the first suction cup, the second suction cup and the channel in real time, so as to promptly detect when leakage occurs in the first suction cup and the second suction cup, thereby ensuring the reliability of the connection between the first shell and the second shell.

[0049] In one of the embodiments, the battery case includes a frame for supporting the battery cells, the frame is connected to the first shell, and the structural member is fixedly or detachably connected to the frame.

[0050] In this example, the frame for assembling the battery cells located in the inner cavity of the first shell has a stronger structural stability. Therefore, arranging the structural parts on the frame can improve the deformation resistance between the first shell and the second shell and enhance the connection reliability.

[0051] In one of the embodiments, the battery box includes a support beam, the support beam is connected to the first shell, and the structural member is fixedly or detachably connected to the support beam.

[0052] In this example, by adding a support beam to the first shell, the deformation resistance of the first shell is improved. Therefore, the structural member can be directly connected to the support beam, which can also make the first shell and the second shell have a higher connection stability.

[0081] The battery 100 generally includes a battery case 10 and a battery cell 70. The battery cell 70 is contained in the battery case 10. The battery case 10 is a wrapping structure for containing the battery cell 70. In order to facilitate the installation of the battery cell 70 in the battery case 10, the battery case 10 adopts a split structure. The battery case 10 includes a first shell 12 and a second shell 11. The second shell 11 is detachably connected to the first shell 12. Generally, the second shell 11 is connected to the first shell 12 through a bolt assembly. During the assembly and disassembly process of the second shell 11 and the first shell 12, it is necessary to use external tools such as wrenches to tighten the bolts. During the operation, bolts and nuts are easy to fall off. The process is relatively cumbersome and inconvenient, which affects work efficiency.

[0082] Considering the convenience of assembling the second shell 11 and the first shell 12, the present application adopts an adsorption connection method, and adopts a connecting component 20 that can perform adsorption connection between the second shell 11 and the first shell 12, so that the second shell 11 is adsorbed and fixed on the first shell 12. The adsorption method can reduce the use of external tools and eliminate the need for tedious screwing work, which is conducive to reducing labor intensity and improving work efficiency.

[0083] Specifically, the first aspect of the embodiment of the present application provides a battery case 10, so that the first shell 12 and the second shell 11 are connected by adsorption to improve the convenience of assembling the battery case 10; wherein, it should be noted that the battery case 10 disclosed in the embodiment of the present application is applied to an electrical device using a battery 100 as a power source or various energy storage systems using a battery 100 as an energy storage element.

Among them, the electric toy may include a fixed or mobile electric toy, for example, a game console, 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.

[0084] For the convenience of description, the following embodiments are described by taking a vehicle 1000 as an example of an electrical device according to an embodiment of the present application.

[0085] Please refer to Figure 1 , Figure 1 A schematic diagram of the structure of a vehicle 1000 provided for some embodiments of the present application. The vehicle 1000 may be a fuel vehicle, a gas vehicle or a new energy vehicle, and the new energy vehicle may be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc. A battery 100 is provided inside the vehicle 1000, and the battery 100 may be provided at the bottom, head or tail of the vehicle 1000. The battery 100 may be used to power the vehicle 1000, for example, the battery 100 may be used as an operating power source for the vehicle 1000. The vehicle 1000 may also include a controller 200 and a motor 300, and the controller 200 is used to control the battery 100 to power the motor 300, for example, for starting, navigating and driving the vehicle 1000.

[0086] In some embodiments of the present application, the battery 100 can not only serve as an operating power source for the vehicle 1000, but also serve as a driving power source for the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.

[0087] Please refer to Figure 2 , Figure 2An exploded view of a battery 100 provided for some embodiments of the present application. The battery 100 includes a battery case 10 and a battery cell 70, and the battery cell 70 is contained in the battery case 10. Among them, in the battery 100, there can be multiple battery cells 70, and the multiple battery cells 70 can be connected in series, in parallel, or in mixed connection. Mixed connection means that the multiple battery cells 70 are both connected in series and in parallel. The multiple battery cells 70 can be directly connected in series, in parallel, or in mixed connection, and then the whole formed by the multiple battery cells 70 is contained in the battery case 10; of course, the battery 100 can also be a battery module formed by connecting multiple battery cells 70 in series, in parallel, or in mixed connection, and the multiple battery modules are then connected in series, in parallel, or in mixed connection to form a whole, and contained in the battery case 10. The battery 100 may also include other structures. For example, the battery 100 may also include a busbar component for realizing electrical connection between the multiple battery cells 70.

[0088] The battery cell 70 refers to the smallest unit that constitutes the battery. Each battery cell 70 can be a secondary battery or a primary battery; it can also be a lithium-sulfur battery, a sodium-ion battery or a magnesium-ion battery, but is not limited thereto. The battery cell 70 can be cylindrical, flat, rectangular or other shapes.

[0089] According to some embodiments of the present application, referring to Figure 3 , Figure 3 This is a partial structural diagram of the battery box 10 provided in some embodiments of the present application, and please refer to Figure 4 , Figure 4 A partial structural schematic diagram of a battery case 10 provided for other embodiments of the present application is provided to show the connection relationship between the connecting component 20 and the second shell 11 and the structural component 30. Specifically, an embodiment of the present application provides a battery case 10. The battery case 10 includes a first shell 12, a second shell 11, a structural component 30 and a connecting component 20; the first shell 12 has an inner cavity, and an opening connected to the inner cavity is formed on the first shell 12; the second shell 11 is connected to the first shell 12 and covers the opening; the structural component 30 is connected to the first shell 12; the connecting component 20 is arranged between the second shell 11 and the structural component 30, so as to enable the second shell 11 and the structural component 30 to be adsorbed and connected.

[0090] Among them, the battery case 10 is used to provide a storage space for the battery cell 70, and the battery case 10 can adopt a variety of structures. In some embodiments, the battery case 10 may include a first shell 12 and a second shell 11, the first shell 12 and the second shell 11 cover each other, and the first shell 12 and the second shell 11 jointly define a storage space for accommodating the battery cell 70. The first shell 12 can be a hollow structure with one end open, and the hollow part of the first shell 12 forms an inner cavity. The second shell 11 can be a plate-like structure, and the second shell 11 covers the open side of the first shell 12, so that the first shell 12 and the second shell 11 jointly define a storage space; the first shell 12 and the second shell 11 can also be hollow structures with one side open, and the hollow parts of the first shell 12 and the second shell 11 can both form an inner cavity, and the open side of the first shell 12 covers the open side of the second shell 11. Of course, the battery case 10 formed by the first shell 12 and the second shell 11 can be a variety of shapes, such as a cylinder, a cuboid, etc.

[0091] Taking the first shell 12 as a hollow structure as an example, an inner cavity is formed on the first shell 12, and the inner cavity is used to accommodate the battery cell 70. The battery cell 70 enters and exits the inner cavity through the opening on the first shell 12 that is connected to the inner cavity. The second shell 11 and the first shell 12 are covered to jointly form a accommodating space for accommodating the battery cell 70.

[0092] The structural member 30 may be a plate-like structure or a rod-like structure, and the way in which the structural member 30 is connected to the first shell 12 includes a fixed connection or a detachable connection, wherein the fixed connection method includes welding or one-piece molding; therefore, it can be understood that the structural member 30 may be a part of the first shell 12 or an independent component independent of the first shell 12, for example, the structural member 30 may be a support beam or support rib on the first shell 12, and the structural member 30 is located in the inner cavity of the first shell 12 or on the open end surface of the first shell 12.

[0093] The connecting component 20 is used to enable the second shell 11 to be adsorbed and connected to the structural component 30. It can be seen that the connecting component 20 has at least an adsorption portion that can generate an adsorption force. After the connecting component 20 is arranged between the second shell 11 and the structural component 30, the adsorption portion is adsorbed by the adsorption force, thereby achieving the purpose of fixing the second shell 11 and the structural component 30.

[0094] The adsorption method includes generating an adsorption force by means of negative pressure. For example, the connecting component 20 can generate an adsorption force by means of negative pressure between the second shell 11 or the structural component 30 at the position where it is connected to the second shell 11 or the structural component 30, thereby connecting the second shell 11 and the structural component 30. In addition, the adsorption method may also include magnetic adsorption, etc. For example, the connecting component 20 can be adsorbed and connected to the position where it is connected to the second shell 11 and the structural component 30 by means of magnetic force.

[0095] The connecting component 20 may have one or two adsorption parts. When the connecting component 20 has one adsorption part, the adsorption part can be adsorbed on the second shell 11 or on the structural member 30. Specifically, when the connecting component 20 is connected to the second shell 11, the adsorption part can be adsorbed on the structural member 30. When the connecting component 20 is connected to the structural member 30, the adsorption part can be adsorbed on the second shell 11. When the connecting component 20 has two adsorption parts, the two adsorption parts are adsorbed on the second shell 11 and the structural member 30 respectively, so as to achieve the purpose of connecting the second shell 11 with the structural member 30 and the first shell 12.

[0096] When the battery case 10 in this example is in use, the first shell 12 covers the opening of the second shell 11. After the first shell 12 and the second shell 11 are sealed and connected, the connecting component 20 is connected between the second shell 11 and the structural component 30. The connecting component 20 generates an adsorption force, thereby adsorbing the second shell 11 on the structural component 30. Since the structural component 30 is connected to the first shell 12, it can be known that the connecting component 20 adsorbs and fixes the second shell 11 on the first shell 12, thereby realizing the assembly of the second shell 11 and the first shell 12. It should be pointed out that the purpose of connecting the second shell 11 and the first shell 12 is to jointly enclose and form a accommodating space for accommodating the battery cell 70.

[0097] The battery case 10 in this example adopts a split structure including a first shell 12 and a second shell 11. By providing a connecting component 20 capable of generating an adsorption force, the connecting component 20 is arranged on the second shell 11 and a structural component 30 connected to the first shell 12. The connecting component 20 generates an adsorption force on the second shell 11 or the structural component 30, or the connecting component 20 generates an adsorption force on both the second shell 11 and the structural component 30. The second shell 11 is connected and fixed to the first shell 12 by adsorption. When the adsorption connection is performed, only the connecting component 20 and the second shell 11 or the connecting component 20 need to be connected. The first shell 12 and the second shell 11 can be assembled and disassembled more quickly and conveniently, saving time and effort, which is conducive to improving the work efficiency of the battery case 10 during assembly and disassembly. The use of adsorption can also reduce the wear on the first shell 12 and the second shell 11. Moreover, when vibration occurs, the battery case 10 can increase the main frequency of the second shell 11 and reduce the probability of abnormal noise.

[0098] In some examples, reference Figure 3As shown, the connecting component 20 includes a connecting body 23 and a first suction cup 21 connected to the connecting body 23 . The connecting body 23 is connected to the structural member 30 , and the first suction cup 21 is adsorbed and connected to the second shell 11 .

[0099] Specifically, the connecting body 23 is a structural member used to support and connect the first suction cup 21. The connecting body 23 can adopt a columnar structure or a tubular structure or other special-shaped structures, and the first suction cup 21 can be connected to the connecting body 23 by interference connection, bonding, welding, snap connection, etc. When the connecting body 23 is columnar, the first suction cup 21 can be connected to one end of the connecting body 23 along its axis. Therefore, it can be known that the other end of the connecting body 23 along its axis is connected to the structural member 30.

[0100] Among them, the connection method between the connector 23 and the structural member 30 may include various methods, for example, welding, interference connection, snap connection, threaded connection, bonding or adsorption connection, etc. The adsorption connection may include magnetic adsorption, vacuum adsorption (negative pressure adsorption), etc., so that the connector 23 can be connected to the structural member 30.

[0101] The first suction cup 21 can be made of elastic material, wherein the elastic material can include silicone, rubber, etc.; the first suction cup 21 can generate a vacuum adsorption force between the second shell 11 and the second shell 11 when being fitted and squeezed with the surface of the second shell 11, so that the first suction cup 21 is adsorbed on the second shell 11. The first suction cup 21 is connected to the structural member 30 through the connector 23, and the structural member 30 is connected to the first shell 12. Therefore, it can be known that the first suction cup 21 adsorbs the second shell 11 on the first shell 12. During disassembly, the adsorption force can be eliminated by destroying the vacuum environment between the first suction cup 21 and the second shell 11 by external force, then the first suction cup 21 can be separated from the second shell 11, and the disassembly of the second shell 11 and the first shell 12 is completed.

[0102] In this example, by configuring the first suction cup 21, the first suction cup 21 and the second shell 11 are adsorbed and connected, which can achieve quick adsorption connection between the second shell 11 and the first shell 12, and also make it unnecessary to open holes in the second shell 11, and no need to open holes and connect bolts. After reducing the number of holes on the second shell 11, the airtightness of the accommodating space after the second shell 11 and the first shell 12 are assembled can be increased, thereby reducing the risk of airtight failure of the battery box 10.

[0103] In some examples, reference Figure 3 As shown, the connecting body 23 can be detachably or fixedly connected to the structural member 30 .

[0104] Among them, the detachable connection methods may include threaded connection, snap connection, pin connection and key connection, etc. For example, the connecting body 23 is threadedly connected to the structural member 30, and an external thread structure may be formed on the connecting body 23, then, correspondingly, an internal thread structure is formed on the structural member 30; or, an internal thread structure is formed on the connecting body 23, then, correspondingly, an external thread structure is formed on the structural member 30, and the internal thread structure and the external thread structure are threadedly matched to achieve the connection between the connecting body 23 and the structural member 30.

[0105] The fixed connection methods include welding, interference connection and one-piece molding, among which, in the interference connection method, the connector 23 can be interference-inserted into the socket opened on the structural member 30, or, a socket hole is opened on the connector 23, and an outer protrusion is formed on the structural member 30, and the outer protrusion can be interference-inserted into the socket hole.

[0106] In this example, the connector 23 is connected to the structural member 30 in a detachable or fixed manner. It can be seen that the connecting member 20 will also be connected to the structural member 30 and the first shell 12 when not assembled with the second shell 11, so that the connecting member 20 is not easily separated from the structural member 30 and lost, thereby ensuring the reliability of the connection between the connecting member 20 and the structural member 30 and the first shell 12.

[0107] Optionally, in some examples, reference Figure 4 As shown, the connecting component 20 includes a connecting body 23 and a first suction cup 21 connected to the connecting body 23 . The connecting body 23 is connected to the second shell 11 , and the first suction cup 21 is adsorbed and connected to the structural member 30 .

[0108] Similarly, the connection method between the connector 23 and the second shell 11 may include various methods, such as welding, interference connection, snap connection, threaded connection, bonding or adsorption connection, etc. The adsorption connection may include magnetic adsorption, vacuum adsorption (negative pressure adsorption), etc., so that the connector 23 can be connected to the second shell 11.

[0109] Similarly, the first suction cup 21 can be made of elastic material, wherein the elastic material may include silicone, rubber, etc.; the first suction cup 21 can generate a vacuum adsorption force between the first suction cup 21 and the structural member 30 when being fitted and squeezed with the surface of the structural member 30, so that the first suction cup 21 is adsorbed on the structural member 30, and the structural member 30 is connected to the first shell 12, and the first suction cup 21 is connected to the second shell 11 through the connector 23, so it can be known that the first suction cup 21 adsorbs the first shell 12 on the second shell 11. During disassembly, the adsorption force can be eliminated by destroying the vacuum environment between the first suction cup 21 and the structural member 30 by external force, then the first suction cup 21 can be separated from the structural member 30, and the disassembly of the second shell 11 and the first shell 12 is completed.

[0110] In this example, by configuring the first suction cup 21, the first suction cup 21 and the structural member 30 are adsorbed and connected, so that the second shell 11 and the first shell 12 can be quickly adsorbed and connected, which is beneficial to improving the convenience of connecting and disassembling the second shell 11 and the first shell 12 and improving work efficiency.

[0111] In some examples, reference Figure 3 As shown, the connecting body 23 can be detachably or fixedly connected to the second shell 11 .

[0112] Similarly, the detachable connection methods may include threaded connection, snap connection, pin connection and key connection, etc. For example, the connecting body 23 is threadedly connected to the second shell 11, and an external thread structure may be formed on the connecting body 23, then, correspondingly, an internal thread structure is formed on the second shell 11; or, an internal thread structure is formed on the connecting body 23, then, correspondingly, an external thread structure is formed on the second shell 11, and the internal thread structure and the external thread structure are threadedly matched, thereby realizing the connection between the connecting body 23 and the second shell 11.

[0113] The fixed connection methods include welding, interference connection and one-piece molding, among which, in the interference connection method, the connector 23 can be interference-inserted into the socket opened on the second shell 11, or, a socket hole is opened on the connector 23, and an outer protrusion is formed on the second shell 11, and the outer protrusion can be interference-inserted into the socket hole.

[0114] In this example, the connector 23 is connected to the second shell 11 in a detachable or fixed manner. It can be seen that the connecting component 20 will also be connected to the second shell 11 when not assembled with the structural member 30, so that the connecting component 20 is not easily separated from the second shell 11 and lost, thereby ensuring the reliability of the connection between the connecting component 20 and the second shell 11; in addition, by welding or one-piece molding, there is no need to perform hole drilling operations on the second shell 11. After reducing the number of holes on the second shell 11, the airtightness of the accommodating space after the second shell 11 and the first shell 12 are assembled can be increased, thereby reducing the risk of airtight failure of the battery case 10.

[0115] In some examples, reference Figure 5 As shown, a connecting head 22 is formed on the connecting body 23, and the connecting head 22 includes a plurality of annular tooth structures 221 protruding from the surface of the connecting head 22, and the plurality of annular tooth structures 221 are arranged at intervals along a preset direction on the connecting body 23, or, the plurality of annular tooth structures 221 are transitionally connected along a preset direction on the connecting body 23 to form a spiral shape; the connecting head 22 is connected to the structural member 30 or the second shell 11 through the annular tooth structure 221.

[0116] Specifically, a plurality of ring tooth structures 221 are arranged at intervals along a preset direction on the connector 23, which means that the ring tooth structure 221 extends outward from the surface of the connector 23 along the central axis of the connector 23 toward a direction away from the connector 23 to form a conical thin shell, and the ring tooth structure 221 expands in a direction close to the first suction cup 21, that is, the ring tooth structure 221 is conical, and the larger end of the ring tooth structure 221 is close to the first suction cup 21; a plurality of ring tooth structures 221 are arranged in sequence at intervals along the central axis of the connector 23 to form a multi-layer conical structure, and the ring tooth structure 221 can be screwed with the matching structure on the structural member 30 or the second shell 11 to achieve the purpose of fixation.

[0117] Alternatively, the plurality of ring tooth structures 221 are connected in a spiral transition manner to form a threaded structure, so that the connector 22 and the structural member 30 or the second housing 11 are fixed by a threaded connection.

[0118] In this example, the end of the connector 23 away from the first suction cup 21 is detachably connected to the structural member 30 or the second shell 11. The design of the ring tooth structure 221 allows the connector 23 to be detachably connected by screwing, making the connection more reliable.

[0119] In some examples, reference Figure 6 As shown, the first suction cup 21 is extended outward from the connection position with the connecting body 23 toward the direction away from the connecting body 23, and a first adsorption groove 211 is formed at the extended end.

[0120] Specifically, the first suction cup 21 adopts a conical suction cup structure. The first suction cup 21 extends outward from the connection position with the connecting body 23 toward the direction away from the connecting body 23 to form a cone shape, and a first adsorption groove 211 is formed at the center of the extended end. The groove of the first adsorption groove 211 is the suction cup mouth. The suction cup mouth of the first suction cup 21 is located at the end opposite to the connecting body 23.

[0121] For example, when the first suction cup 21 is connected to the second shell 11 by adsorption, the suction cup mouth of the first suction cup 21 is made to abut against the surface of the second shell 11, squeezing the first suction cup 21 and exhausting the air in the first adsorption groove 211, so that negative pressure is generated in the first adsorption groove 211. The first suction cup 21 generates an adsorption force with the surface of the second shell 11 due to the negative pressure, thereby being adsorbed on the second shell 11.

[0122] In this example, the first suction cup 21 expands outward to form a cone and forms a first adsorption groove 211. The adsorption force is generated by exhausting air from the first adsorption groove 211 to generate negative pressure. The first suction cup 21 can be used manually, which is convenient and flexible to use and helps to improve work efficiency.

[0123] In some examples, reference Figure 7 and Figure 8 As shown, the connecting component 20 further includes a second suction cup 24 , which is connected to the connecting body 23 , and the connecting body 23 is adsorbed on the structural member 30 via the second suction cup 24 , and the first suction cup 21 is adsorbed on the second shell 11 .

[0124] Specifically, the second suction cup 24 can be made of elastic material, wherein the elastic material can include silicone, rubber, etc.; the second suction cup 24 can generate a vacuum adsorption force between the second suction cup 24 and the structural member 30 when being fitted and squeezed with the surface of the structural member 30, so that the second suction cup 24 is adsorbed on the structural member 30, and the structural member 30 is connected to the first shell 12, so it can be known that the second suction cup 24 and the first shell 12 are adsorbed and connected. During disassembly, the vacuum environment between the second suction cup 24 and the structural member 30 can be destroyed by external force to eliminate the adsorption force, so that the second suction cup 24 can be separated from the structural member 30, and the disassembly of the connecting component 20 and the first shell 12 is completed.

[0125] In this example, the connecting component 20 includes a connecting body 23 and a first suction cup 21 and a second suction cup 24 respectively connected to the connecting body 23. The first suction cup 21 and the second suction cup 24 can be arranged opposite to each other. It can be seen that the connecting component 20 is an independent component that is independent of the first shell 12, the second shell 11 and the structural member 30. By adding a connecting component 20 between the first shell 12 and the second shell 11, and adsorbing the second shell 11 by the first suction cup 21, and adsorbing the structural member 30 on the first shell 12 by the second suction cup 24, an adsorption connection between the first shell 12 and the second shell 11 is achieved, so that when installing and disassembling the battery box 10, vacuum adsorption can be achieved by squeezing the first suction cup 21 and the second suction cup 24, which makes the operation more convenient and helps to improve work efficiency.

[0126] In some examples, reference Figure 8 As shown, the second suction cup 24 is extended outward from the connection position with the connecting body 23 toward a direction away from the connecting body 23, and a second adsorption groove 241 is formed at the extended end.

[0127] Specifically, the second suction cup 24 adopts a conical suction cup structure. The second suction cup 24 extends outward from the connection position with the connecting body 23 toward the direction away from the connecting body 23 to form a cone shape, and a second adsorption groove 241 is formed at the center of the extended end. The groove of the second adsorption groove 241 is the suction cup mouth. The suction cup mouth of the second suction cup 24 is located at the end opposite to the connecting body 23.

[0128] For example, when the second suction cup 24 is adsorbed and connected to the structural member 30, the suction cup mouth of the second suction cup 24 is brought into contact with the surface of the structural member 30, squeezing the second suction cup 24 to discharge the air in the second adsorption groove 241, thereby generating a negative pressure in the second adsorption groove 241. The second suction cup 24 generates an adsorption force with the surface of the structural member 30 due to the negative pressure, thereby being adsorbed on the structural member 30.

[0129] In this example, the second suction cup 24 expands outward to form a cone and forms a second adsorption groove 241. The adsorption force is generated by exhausting air from the second adsorption groove 241 to generate negative pressure. The second suction cup 24 can be used manually, which is convenient and flexible to use and helps to improve work efficiency.

[0130] In some examples, reference Figure 3 As shown, the connecting body 23 is configured to extend in a columnar shape, the first suction cup 21 is connected to one extending end of the connecting body 23, and the connecting head 22 is formed at the other extending end of the connecting body 23; or, the second suction cup 24 is connected to the other extending end of the connecting body 23, so that the first suction cup 21 and the second suction cup 24 are configured to face each other.

[0131] Specifically, the connector 23 can be prepared using a columnar structure or a cylindrical structure, and the outer contour of the cross section of the connector 23 can be circular, elliptical, polygonal or other special shapes; when the connector 23 adopts a hollow cylindrical structure, it is beneficial to reduce the overall weight of the connecting component 20.

[0132] In this example, a columnar connector 23 is used, and the first suction cup 21 and the second suction cup 24 are respectively arranged at its two ends, or the first suction cup 21 and the connecting head 22 are respectively arranged at the two ends of the connector 23. Then, the connecting component 20 can form a stable support between the second shell 11 and the structural member 30, which is beneficial to improve the stability of the support. In addition, the overall structure of the connecting component 20 is simpler, which is beneficial to improve the convenience of processing.

[0133] In some examples, reference Fig.14 As shown, a plurality of connecting components 20 are provided, and the plurality of connecting components 20 are arranged between the second housing 11 and the structural member 30 at intervals.

[0134] Specifically, a connecting component 20 can be provided to achieve the effect of adsorbing the second shell 11 onto the structural component 30 and the first shell 12. However, the adsorption force of a connecting component 20 is limited. Therefore, in this example, multiple connecting components 20 are configured, and the multiple connecting components 20 are distributed between the second shell 11 and the structural component 30 at intervals, so that when the second shell 11 and the first shell 12 are snapped or closed, the multiple connecting components 20 can be adsorbed between the second shell 11 and the structural component 30 at the same time.

[0135] In this example, by configuring multiple connecting components 20, when the second shell 11 is connected to the first shell 12, the multiple connecting components 20 can provide adsorption force, thereby improving the connection strength and firmness, making the connection between the second shell 11 and the first shell 12 more secure.

[0136] In some examples, reference Fig. 9 and Fig.10 As shown, the battery box 10 further includes a pipe component 40 and a control valve 50 . A channel 44 is formed inside the pipe component 40 . The channel 44 is connected to both the first suction cup 21 and the control valve 50 .

[0137] Specifically, the pipe component 40 can be prepared using a tubular structure or a cylindrical structure. A channel 44 is formed in the middle of the pipe component 40. The channel 44 needs to be connected to the first adsorption groove 211 of the first suction cup 21. It can be seen that when the channel 44 is vacuumed, a negative pressure can be formed in the first adsorption groove 211 to generate adsorption force.

[0138] The pipe component 40 can be directly connected to the first suction cup 21, so that the channel 44 of the pipe component 40 is directly connected to the first adsorption groove 211 of the first suction cup 21. Alternatively, the pipe component 40 can also be connected to the connecting body 23, and a connecting cavity is opened inside the connecting body 23. The connecting cavity is respectively connected to the channel 44 and the first adsorption groove 211, thereby realizing the connection between the channel 44 and the first adsorption groove 211.

[0139] The control valve 50 can be connected to the pipeline component 40. The control valve 50 can realize the connection and blocking of the channel 44 with the external space. When the control valve 50 is closed and the first suction cup 21 is adsorbed on the second shell 11 or the structural member 30, a closed environment can be formed in the first adsorption groove 211 and the channel 44. A monitoring component 60 for detecting pressure can be connected at the position of the control valve 50, or an exhaust component can be connected.

[0140] The control valve 50 may be a manually controlled valve or an automatically controlled valve. For example, the control valve 50 may be a stop valve, a butterfly valve, a ball valve, an electric regulating valve, a pneumatic regulating valve, and the like.

[0141] In this example, by configuring the pipe component 40, the channel 44 inside the pipe component 40 is connected to the first suction cup 21, so that the purpose of generating negative pressure in the first suction groove 211 can be achieved by directly controlling the pressure in the channel 44. The pipe component 40 can be extended to a position far away from the first suction cup 21, and combined with an external air extraction component, etc., so as to achieve the purpose of remote adsorption control of the first suction cup 21. The control valve 50 can control the channel 44 to communicate with the external space. When the air extraction component is connected to the position of the control valve 50, the purpose of vacuuming the channel 44 can also be achieved, so that the first suction cup 21 can achieve the purpose of rapid adsorption.

[0142] Optionally, in some examples, reference Fig. 9 and Fig.10 As shown, when the connecting component 20 also includes the second suction cup 24, the battery box 10 includes a pipe component 40 and a control valve 50, and a channel 44 is formed inside the pipe component 40, and the channel 44 is connected to the first suction cup 21, the second suction cup 24 and the control valve 50.

[0143] Specifically, the pipe component 40 can be prepared using a tubular structure or a cylindrical structure, and a channel 44 is formed in the middle of the pipe component 40. The channel 44 needs to be connected to the first adsorption groove 211 of the first suction cup 21 and the second adsorption groove 241 of the second suction cup 24. It can be seen that when the channel 44 is vacuumed, negative pressure can be formed in the first adsorption groove 211 and the second adsorption groove 241 to generate adsorption force.

[0144] The pipe component 40 may have two connection ports, which are directly connected to the first suction cup 21 and the second suction cup 24 respectively, so that the channel 44 of the pipe component 40 is directly connected to the first adsorption groove 211 and the second adsorption groove 241. Alternatively, the pipe component 40 may also be connected to the connecting body 23, and a connecting cavity is opened inside the connecting body 23. The connecting cavity is connected to the channel 44 and the first adsorption groove 211 and the second adsorption groove 241 respectively, thereby realizing the connection between the channel 44 and the first adsorption groove 211 and the second adsorption groove 241.

[0145] Similarly, the control valve 50 can be connected to the pipeline component 40. The control valve 50 can realize the connection and blocking of the channel 44 with the external space. When the control valve 50 is closed, a closed environment can be formed in the first adsorption groove 211, the second adsorption groove 241 and the channel 44. A monitoring component 60 for detecting pressure can be connected at the position of the control valve 50, or an exhaust component can be connected.

[0146] Likewise, the control valve 50 may be a manually controlled valve or an automatically controlled valve. For example, the control valve 50 may be a stop valve, a butterfly valve, a ball valve, an electric regulating valve, a pneumatic regulating valve, and the like.

[0147] In this example, by configuring the pipe component 40, the channel 44 inside the pipe component 40 is connected to the first suction cup 21 and the second suction cup 24, so that the purpose of generating negative pressure in the first adsorption groove 211 and the second adsorption groove 241 can be achieved by directly controlling the pressure in the channel 44. The pipe component 40 can be extended to a position far away from the first suction cup 21 and the second suction cup 24, and combined with an external air extraction component, etc., so as to achieve the purpose of remote adsorption control of the first suction cup 21 and the second suction cup 24. The control valve 50 can control the channel 44 to communicate with the external space. When the air extraction component is connected to the position of the control valve 50, the purpose of vacuuming the channel 44 can also be achieved, so that the first suction cup 21 and the second suction cup 24 can achieve the purpose of rapid adsorption.

[0148] In some examples, reference Figure 3 As shown, the battery case 10 further includes an air extraction component, which is in communication with the channel 44 .

[0149] Specifically, the air extraction component can be operated manually or electrically, for example, the air extraction component can be a manual air extraction pump or an electric air extraction pump, etc. The air extraction component can be connected to the pipeline component 40 and can be communicated with the channel 44 to evacuate the channel 44, so that a negative pressure environment is formed inside the channel 44, thereby enabling the first suction cup 21 and the second suction cup 24 to generate adsorption force.

[0150] In this example, by configuring the vacuum component, when the first suction cup 21 and the second suction cup 24 are in use, after the first suction cup 21 is in contact with the surface of the second shell 11 and the second suction cup 24 is in contact with the surface of the structural member 30, there is no need to squeeze them, and only the vacuum component needs to be operated to generate negative pressure in the first adsorption groove 211 and the second adsorption groove 241, so that the first suction cup 21 and the second shell 11, as well as the second suction cup 24 and the structural member 30 can be automatically adsorbed; in addition, when air leakage occurs at the position of the first suction cup 21 and the second suction cup 24, resulting in a decrease in the adsorption force, by operating the vacuum component, the first suction cup 21 and the second suction cup 24 can be further evacuated, thereby increasing the adsorption force at the position of the first suction cup 21 and the second suction cup 24, and improving the connection strength and connection reliability.

[0151] In some examples, reference Fig. 9 , Fig.10 and Fig.14 As shown, the control valve 50 is installed on the first housing 12 or the second housing 11 .

[0152] Specifically, in the case of only the first suction cup 21, when the first suction cup 21 is connected to the structural member 30 through the connecting body 23, the end of the pipe component 40 can extend to the first shell 12, so that the control valve 50 is connected to the end of the pipe component 40 and installed on the first shell 12; when the first suction cup 21 is connected to the second shell 11 through the connecting body 23, the end of the pipe component 40 can extend to the second shell 11, so that the control valve 50 is connected to the end of the pipe component 40 and installed on the second shell 11.

[0153] When the connecting component 20 has a first suction cup 21 and a second suction cup 24, the first suction cup 21 is adsorbed and connected to the second shell 11, and the second suction cup 24 is adsorbed and connected to the structural member 30. When the second shell 11 is a plate-like structure, the inner cavity of the first shell 12 is used to accommodate the battery cell 70 or the battery core, and the end of the pipe component 40 can extend to the first shell 12, so that the control valve 50 is connected to the first shell 12.

[0154] In this example, the control valve 50 can be connected to an external vacuum component to perform a vacuum operation on the channel 44. The control valve 50 is connected to the first shell 12 or the second shell 11. Then, the vacuum component can be directly connected to the first shell 12 or the second shell 11, and the vacuum component is connected to the control valve 50. When the vacuum component is working, it can control the adsorption force of the first suction cup 21 and the second suction cup 24 outside the first shell 12 and the second shell 11, thereby improving the convenience of operation.

[0155] In some examples, reference Fig.14 As shown, there are multiple connecting components 20, and the multiple connecting components 20 are arranged at intervals between the second shell 11 and the structural member 30; there are multiple pipe components 40, and the multiple connecting components 20 are connected by the pipe components 40 so that the channels 44 in each pipe component 40 are connected.

[0156] Specifically, the connecting component 20 can simultaneously play the role of adsorption between the second shell 11 and the structural component 30. It can be seen that by configuring a plurality of connecting components 20, the connection strength between the second shell 11 and the structural component 30 can be enhanced, and the connection reliability can be improved.

[0157] Correspondingly, a plurality of pipe components 40 are configured, and the plurality of pipe components 40 are connected between the plurality of connecting components 20. For example, two adjacent connecting components 20 are connected via a pipe component 40, and the ends of each pipe component 40 are connected to the connecting body 23, and a connecting hole connecting the first adsorption groove 211 and the second adsorption groove 241 is provided on the connecting body 23, so that the ends of the two adjacent pipe components 40 are connected to the connecting hole, so that the channels 44 in each pipe component 40 are connected, and then, the first adsorption groove 211 and the second adsorption groove 241 on the plurality of connecting components 20 can be connected to each other.

[0158] In this example, multiple connecting components 20 are simultaneously connected between the second shell 11 and the first shell 12, which can enhance the connection strength between the second shell 11 and the first shell 12. In addition, by configuring the pipe component 40, the pipe component 40 connects the first adsorption groove 211 and the second adsorption groove 241 of each connecting component 20. Therefore, when the vacuum component vacuums the channel 44 in the pipe component 40, the first suction cup 21 and the second suction cup 24 on all the connecting components 20 can simultaneously generate negative pressure, and then generate adsorption force at the same time. The adsorption effect of all the connecting components 20 on the first shell 12 and the second shell 11 can be completed in one operation, and the convenience is improved.

[0159] In some examples, reference Figure 11-13 As shown, the pipeline component 40 includes a connecting pipe 41 and a sleeve 42 , one end of the connecting pipe 41 is connected to the connecting body 23 , the other end of the connecting pipe 41 is detachably connected to the sleeve 42 , and a channel 44 is formed in the connecting pipe 41 and the sleeve 42 .

[0160] Specifically, a channel 44 is formed inside the connecting tube 41, one end of the connecting tube 41 is connected to the connecting body 23, and a connecting hole is formed in the connecting body 23, which is connected to the first suction cup 21, or the second suction cup 24, or both the first suction cup 21 and the second suction cup 24, so that the channel 44 in the connecting tube 41 is connected to the first suction cup 21 and the second suction cup 24 through the connecting hole.

[0161] The length of the connecting tube 41 can be smaller than the distance between two adjacent connecting parts 20, and the length of the connecting tube 41 can be set close to the length of the connecting body 23. The length of the connecting tube 41 is shorter, so that the connecting tube 41 can be welded or integrally formed with the connecting body 23, which facilitates the integrated preparation of the connecting tube 41 and the connecting body 23.

[0162] The sleeve 42 adopts a hollow thin-walled tube structure, and a channel 44 is formed inside the sleeve 42. One end of the sleeve 42 is sleeved and connected to the extended end of the connecting tube 41, and the connecting position between the sleeve 42 and the connecting tube 41 is sealed; the length of the sleeve 42 is greater than the length of the connecting tube 41, so that the sleeve 42 can connect two adjacent connectors 23.

[0163] In this example, the pipe component 40 is in the form of a combination of a connecting pipe 41 and a sleeve 42, so that the sleeve 42 in the pipe component 40 and the connecting component 20 can be independently installed and disassembled, respectively, making the overall structure formed by the pipe component 40 and the connecting component 20 more convenient and flexible during disassembly and installation.

[0164] In some examples, reference Figure 11-13 As shown, the sleeve 42 is sleeved on the other end of the connecting pipe 41 ; the pipeline component 40 further includes a sealing member 43 , which is connected between the sleeve 42 and the connecting pipe 41 .

[0165] Specifically, the seal 43 can be made of elastic material, for example, the elastic material can be silicone, rubber, etc. The seal 43 can include a plurality of sealing ring bodies arranged around the outer peripheral surface of the connecting tube 41, and the plurality of sealing ring bodies are arranged at intervals along the central axis of the connecting tube 41 to form a multi-layer seal. The sealing surface of each sealing ring body can be gradually expanded from the connection position with the connecting tube 41 to the direction away from the connecting tube 41 along the central axis of the connecting tube 41, and the outer expansion end of the sealing ring body is arranged toward the connecting body 23.

[0166] In this example, a seal 43 is provided at the connection position between the sleeve 42 and the connecting tube 41 to improve the sealing performance of the connection position between the sleeve 42 and the connecting tube 41 and reduce the possibility of air leakage, thereby ensuring the pressure state in the channel 44, the first adsorption groove 211 and the second adsorption groove 241, and ensuring the reliability of the connection between the connecting component 20 and the first shell 12 and the second shell 11.

[0167] In some examples, reference Fig.14 As shown, there are multiple connecting components 20, which are arranged at intervals between the second shell 11 and the structural member 30; there are multiple pipe components 40, which are connected by sleeves 42 so that the channels 44 in each sleeve 42 are connected.

[0168] Specifically, multiple connecting components 20 are connected by multiple pipe components 40, so that the channel 44 in each pipe component 40 is connected to the first suction cup 21 and the second suction cup 24 of the connecting component 20. For example, between two adjacent connecting components 20, each connecting body 23 is connected to a connecting pipe 41, and a sleeve 42 is sleeved on the outside of the connecting pipe 41. The two sleeves 42 are docked to make the channel 44 in the sleeve 42 connected. It can be understood that in actual applications, the two sleeves 42 between the two adjacent connecting components 20 can be formed as one piece.

[0169] In this example, the connecting tube 41 is connected to the connecting body 23, and the sleeve 42 and the connecting tube 41 can be detachably connected, so the sleeve 42 and the connecting component 20 can be independently installed and disassembled respectively. The sleeve 42 extends from the connection position with the connecting tube 41 in a direction away from the connecting tube 41 to communicate with another sleeve 42, so that the sleeves 42 are mutually connected and communicated with each other, so that the various connecting components 20 can be connected and form a whole. The overall structure formed by the pipeline component 40 and the connecting component 20 is more convenient and flexible during disassembly and installation.

[0170] In some examples, reference Fig.10 and Fig.14 As shown, the battery box 10 further includes a monitoring component 60 , which is connected to the connecting component 20 to monitor the adsorption pressure between the second shell 11 and the structural member 30 .

[0171] Specifically, the monitoring component 60 may include a pressure sensor, a pressure transmitter and a pressure gauge, etc. The monitoring component 60 is used to monitor or detect the vacuum pressure on the first suction cup 21 and the second suction cup 24 on the connecting component 20. Therefore, it can be seen that the monitoring component 60 can be directly connected to the connecting body 23 or the first suction cup 21 or the second suction cup 24, so that the monitoring component 60 is connected to the first adsorption groove 211 and the second adsorption groove 241, or the monitoring component 60 can also be connected to the pipeline component 40, so that the monitoring component 60 is connected to the channel 44. Since the channel 44 is connected to the first adsorption groove 211 and the second adsorption groove 241, it can be seen that the monitoring component 60 is connected to the first adsorption groove 211 and the second adsorption groove 241.

[0172] The monitoring component 60 can transmit the detected pressure numerical signal to the external control component. The control component can be connected to the vacuum component for communication. The control component can control the vacuum component through a set program according to the pressure numerical signal. For example, when the pressure value detected is less than the preset value, the control component controls the vacuum component to start vacuuming, thereby increasing the negative pressure value at the positions of the first suction cup 21 and the second suction cup 24, increasing the adsorption force, and ensuring the reliability of the connection between the first shell 12 and the second shell 11.

[0173] In this example, the monitoring component 60 can monitor the pressure values ​​of the first suction cup 21, the second suction cup 24 and the channel 44 in real time, so as to promptly detect when leakage occurs in the first suction cup 21 and the second suction cup 24, thereby ensuring the reliability of the connection between the first shell 12 and the second shell 11.

[0174] In some examples, the battery case 10 includes a frame for supporting the battery cells, the frame is connected to the first shell 12, and the structural member 30 is fixedly or detachably connected to the frame.

[0175] Specifically, the frame can be prepared using a plate-shaped or rod-shaped structure, and multiple installation spaces can be formed in the frame. Battery cells, battery cells 70 or battery modules 100 are installed in the installation spaces. The frame is used to support the battery cells, battery cells 70 and battery modules 100.

[0176] The structural member 30 can be connected to the side of the frame facing the second shell 11. The structural member 30 can be fixedly connected to the frame. The fixed connection method includes welding and integral molding. When the structural member 30 and the frame are integrally molded, it can also be considered that the structural member 30 is a part of the frame. The structural member 30 can also be connected to the frame in a detachable manner. The detachable connection method includes threaded connection, snap connection, etc. The frame is accommodated in the inner cavity of the first shell 12. In order to ensure the stability of the frame, the frame is generally connected to the first shell 12. Therefore, it can be known that the positions of the structural member 30 and the first shell 12 are relatively fixed. It can be considered that the structural member 30 is connected to the first shell 12.

[0177] In this example, considering that the first shell 12 is generally prepared with a thin shell structure, the overall deformation resistance of the first shell 12 can be relatively weak, but the structural stability of the frame for assembling battery cells located in the inner cavity of the first shell 12 is stronger. Therefore, arranging the structural member 30 on the frame can improve the deformation resistance between the first shell 12 and the second shell 11, and can improve the connection reliability.

[0178] In some examples, reference Figure 3 , Figure 4 and Fig.14 As shown, the battery box 10 includes a support beam, the support beam is connected to the first shell 12, and the structural member 30 is fixedly or detachably connected to the support beam.

[0179] Specifically, the support beam can adopt a plate-shaped or rod-shaped structure. The support beam is a support member connected to the first shell 12 to strengthen and stabilize the first shell 12, for example, a ring-shaped support beam arranged on the inner wall of the cavity opening of the inner cavity of the first shell 12.

[0180] Similarly, the fixed connection methods include welding and integral molding. When the structural member 30 and the support beam are integrally molded, it can be considered that the support beam is a part of the first shell 12; the structural member 30 can also be connected to the support beam in a detachable manner. The detachable connection methods include threaded connection, snap connection, etc.

[0181] In this example, by adding a support beam to the first shell 12, the deformation resistance of the first shell 12 is improved. Therefore, the structural member 30 can be directly connected to the support beam, which can also make the first shell 12 and the second shell 11 have a higher connection stability.

[0182] Based on the above-mentioned battery case 10, the present application further proposes an example of a battery 100. The battery 100 includes the battery case 10 and a battery cell 70 as described in any of the above-mentioned examples.

[0183] The battery 100 in this example includes a battery case 10 and a battery cell 70, and the battery cell 70 is installed in the battery case 10. The battery 100 may include one battery cell 70, or may include multiple battery cells 70. When multiple battery cells 70 are provided in the battery 100, the multiple battery cells 70 may be arranged according to a preset rule. The multiple battery cells 70 may be arranged in a row of multiple columns or multiple rows of multiple columns. The multiple battery cells 70 may be connected in series, in parallel, or in series-parallel hybrid.

[0184] It is understandable that in this example, only the battery 100 including the above-mentioned battery cell 70 is described, and the battery 100 may also include other functional components, which will not be described in detail.
