Background Art

[0003] Energy conservation and emission reduction are key points in the sustainable development of the automotive industry. Electric vehicles, due to their advantages of energy conservation and environmental friendliness, have become an important part of the sustainable development of the automotive industry. For electric vehicles, battery technology is an important factor related to their development.

[0004] In the development of battery technology, how to improve the reliability of batteries is an urgent technical problem to be solved in battery technology.

Summary of the Invention

[0005] This application provides a housing, a battery and a power - consuming device, and the reliability of the battery can be improved by the technical solution according to this application.

[0006] This application is realized by the following technical solutions.

[0007] According to a first aspect, this application provides a housing applied to a battery. The housing includes a first housing, a second housing, a first sealing member and a position - regulating portion. The first housing has a first sealing surface. The second housing has a second sealing surface. The first sealing member is provided between the first sealing surface and the second sealing surface to seal - connect the first sealing surface and the second sealing surface. The position - regulating portion is convexly provided on the second sealing surface and is used to regulate the movement of the first sealing member.

[0008] In the above technical solution, by providing a position-regulating portion on the second sealing surface, the movement of the first sealing member can be effectively restricted, reducing the risk of loss of the sealing effect between the first and second sealing surfaces due to misalignment of the first sealing member during housing assembly. This results in a highly reliable housing and, consequently, improved battery reliability.

[0009] According to some embodiments of the present application, the position regulating portion includes a first position regulating projection and a second position regulating projection provided at intervals, and the first sealing member is positioned between the first position regulating projection and the second position regulating projection.

[0010] In the above technical solution, by providing a first position-regulating projection and a second position-regulating projection spaced apart from each other on the second sealing surface, and positioning the first and second position-regulating projections on both sides of the first sealing member, the movement of the first sealing member can be effectively restricted, the first sealing member can be held in the correct position, the risk of loss of sealing effect between the first and second sealing surfaces due to misalignment of the first sealing member during housing assembly can be reduced, the housing can have high reliability, and consequently the reliability of the battery can be improved.

[0011] According to some embodiments of the present application, let b be the width of the first sealing member in its natural state. Let B be the minimum distance between the first position regulating projection and the second position regulating projection along the direction of spacing between them, satisfying b+2mm ≤ B ≤ b+20mm.

[0012] When assembling the housing, the first housing and the second housing are connected to each other, and the first sealing member located between the first sealing surface and the second sealing surface is compressed. That is, the first sealing member, in its natural state, is deformed and compressed by the forces acting from the first housing and the second housing, and the width of the first sealing member increases. By limiting the numerical relationship between the minimum distance B between the first position regulating projection and the second position regulating projection and the width b of the first sealing member in its natural state, the above technical solution effectively reduces the risk of the first sealing member interfering with the position regulating part after compression, resulting in damage to the first sealing member and a decrease in the sealing effect. As a result, the housing has high reliability, and consequently the battery has reliability.

[0013] According to some embodiments of the present application, let h be the thickness of the first sealing member in its natural state. Let H1 be the height at which the position regulating portion protrudes from the second sealing surface, satisfying 0.3h ≤ H1 ≤ 0.7h.

[0014] When assembling the housing, the first housing and the second housing are connected to each other, and the first sealing member located between the first sealing surface and the second sealing surface is compressed. That is, the first sealing member in its natural state is deformed and compressed by the forces acting from the first housing and the second housing, and the height of the first sealing member decreases. According to the above technical solution, by limiting the numerical relationship between the height H1 to which the position regulating portion protrudes from the second sealing surface and the thickness h of the first sealing member in its natural state, the height of the first sealing member decreases after compression, and as a result the position regulating portion interferes with the first sealing surface, the risk of the first sealing surface being damaged and the sealing effect decreasing can be effectively reduced, the housing can have high reliability, and consequently the battery can have high reliability.

[0015] According to some embodiments of the present invention, the housing further includes a connecting member, and the first sealing surface and the second sealing surface are connected by the connecting member.

[0016] In the above technical solution, by providing a connecting member that connects the first sealing surface and the second sealing surface, the sealing effect of the first sealing surface and the second sealing surface can be effectively enhanced, the connection stability between the first sealing surface and the second sealing surface can be improved, the structural stability of the housing can be enhanced, and the battery can have high reliability.

[0017] According to some embodiments of the present application, the projection of the connecting member along a direction perpendicular to the second sealing surface does not overlap with the projection of the first sealing member.

[0018] In the above technical solution, by positioning the first sealing member and the connecting member offset from each other on the second sealing member, they do not interfere with each other, and the interference that the connecting member causes to the first sealing member can be reduced. As a result, the first sealing member can exert an effective sealing effect between the first sealing surface and the second sealing surface, and the risk of the first sealing member being damaged and failing to seal due to the connecting member penetrating the first sealing member can be reduced.

[0019] According to some embodiments of the present invention, the first housing and the second housing jointly enclose a sealed space for housing a battery cell. The second sealing surface has a first edge close to the sealed space and a second edge further away from the sealed space, and the first sealing member is closer to the first edge than the connecting member.

[0020] In the above technical solution, the first edge of the second sealing surface is closer to the sealed space than the second edge, meaning that the side of the second sealing surface away from the second edge can be considered the inside, and the side of the second sealing surface away from the first edge can be considered the outside. Therefore, the first sealing member can be understood to be closer to the first edge than the connecting member, that is, located inside the connecting member. By positioning the first sealing member inside the connecting member, even after the connecting member is damaged and the connection is lost, the first sealing member can still provide a certain sealing effect, resulting in a highly reliable housing and, consequently, a highly reliable battery.

[0021] According to some embodiments of the present invention, a through hole is formed in the first sealing surface, a screw hole is formed in the second sealing surface, and the connecting member passes through the through hole and engages with the screw hole by screwing.

[0022] In the above technical solution, by providing through holes in the first sealing surface and screw holes in the second sealing surface, the connecting member can effectively connect the first sealing surface and the second sealing surface by screw connection, thereby improving the sealing effect of the first and second sealing surfaces as well as the connection stability between them. As a result, the housing can have high reliability, and the battery can have high reliability.

[0023] According to some embodiments of the present invention, the connecting member includes a main body and a first position regulating body, one end of the main body is connected to the first position regulating body, the other end of the main body is screw-fitted to a screw hole, the cross-sectional area of ​​the first position regulating body is larger than the cross-sectional area of ​​the main body, and the first position regulating body is in contact with a surface of the first housing that is away from the second sealing surface.

[0024] In the above technical solution, the connecting member includes a main body and a first position restrictor, and by setting the cross-sectional area of ​​the first position restrictor to be larger than the cross-sectional area of ​​the main body, the surface of the first housing that moves away from the second sealing surface can be effectively restrained, improving the connection stability between the first sealing surface and the second sealing surface, and enhancing the structural stability of the housing.

[0025] According to some embodiments of the present invention, the connecting member further includes a second position regulating body, the second position regulating body is provided between the first position regulating body and the main body, the cross-sectional area of ​​the first position regulating body is larger than the cross-sectional area of ​​the second position regulating body, the cross-sectional area of ​​the second position regulating body is larger than the cross-sectional area of ​​the main body, and a portion of the second position regulating body is located in a through hole and in contact with the second sealing surface.

[0026] In the above technical solution, a second position restricting body is provided between the first position restricting body and the main body, and the cross-sectional area of the second position restricting body is set to be smaller than the cross-sectional area of the first position restricting body and larger than the cross-sectional area of the main body. By doing so, the end surface of the second position restricting body separating from the first position restricting body contacts the second sealing surface, and the depth of screw fitting into the screw hole of the main body can be restricted. Thereby, the degree of compression of the first sealing member is restricted. On one hand, it can reduce the problem that an excessive load acts on the first sealing member due to an excessive screw fitting depth, causing damage and loss of the sealing effect. On the other hand, it can reduce the risk that the first sealing member fails to perform the sealing action or the sealing effect is insufficient due to an insufficient screw fitting depth.

[0027] According to some embodiments of the present application, the first housing includes a first side wall, the through hole is formed in the first side wall, and the first position restricting body contacts the surface separating from the second sealing surface of the first side wall. Let the thickness of the first sealing member in the natural state be h, the thickness of the first side wall be d, and the length of the second position restricting body be H2, and 0.3h + d ≤ H2 ≤ 0.7h + d is satisfied.

[0028] When assembling the housing, the first housing and the second housing are connected to each other, and the first sealing member located between the first sealing surface and the second sealing surface is compressed. That is, the first sealing member in its natural state is deformed and compressed under the acting force from the first housing and the second housing, and the height of the first sealing member decreases. According to the above technical solution, by limiting the numerical relationship among the thickness d of the first side wall, the length H2 of the second position restricting body, and the thickness h of the first sealing member in its natural state, the compression rate of the first sealing member in the thickness direction can be effectively controlled. On the one hand, it can reduce the problem that due to the excessive screw fitting depth, an excessive load acts on the first sealing member, causing damage and loss of the sealing effect. On the other hand, it can reduce the risk that due to the excessive small screw fitting depth, the compression rate of the first sealing member in the thickness direction becomes inappropriate, resulting in the failure to achieve the sealing action or insufficient sealing effect. Furthermore, by controlling the compression rate of the first sealing member in the thickness direction, the risk that the reaction force associated with the screw fitting becomes excessive and damages the first side wall can be reduced, whereby the housing has high reliability, and thus the battery can have high reliability.

[0029] According to some embodiments of the present application, the first sealing surface and the second sealing surface intersect the horizontal plane.

[0030] In the above technical solution, the horizontal plane is a plane perpendicular to the upright direction (in some embodiments, the upright direction may be parallel to the gravity direction). If the first sealing surface and the second sealing surface are limited to intersect the horizontal plane, there is a risk that the first sealing member slides relative to the second sealing surface under the influence of gravity when provided on the second sealing surface. In contrast, by protruding a position restricting portion on the second sealing surface, the displacement of the first sealing member due to the influence of gravity can be effectively restricted, and the risk that the sealing effect between the first sealing surface and the second sealing surface is lost due to the displacement of the first sealing member during the assembly of the housing can be reduced, so that the housing has high reliability, and thus the reliability of the battery can be improved.

[0031] According to some embodiments of the present application, the first sealing surface and the second sealing surface are provided perpendicular to the horizontal plane.

[0032] In the above technical solution, by making the first sealing surface and the second sealing surface perpendicular to the horizontal plane, on the one hand, the space occupied horizontally by the connection between the first housing and the second housing can be saved, and the space occupied by the housing can be reduced. On the other hand, by providing a position regulating portion on the second sealing surface, the gravity of the first sealing member can be effectively overcome and the first sealing member can be held in the correct position, reducing the risk of loss of sealing effect of the first sealing surface and the second sealing surface due to misalignment of the first sealing member during housing assembly, resulting in a highly reliable housing and, consequently, improved battery reliability.

[0033] According to some embodiments of the present application, the first housing includes a first end wall and a first side wall. The second housing includes a second end wall, the second end wall is provided opposite the first end wall along a first direction, the second housing has a second sealing surface in the second direction, the first direction intersects the second direction, the second direction is parallel to the horizontal plane, one end of the first side wall is connected to the first end wall and the other end has a first sealing surface.

[0034] In the above technical solution, by connecting the first sealing surface at one end of the first side wall of the first housing to the second sealing surface of the second housing, the connection between the first housing and the second housing can be achieved without providing a flange structure that protrudes in the second direction. This increases the space utilization rate of the battery in the second direction, making it possible to accommodate more battery cells or reduce the volume of the battery, and ultimately improving the volumetric energy density of the battery.

[0035] According to some embodiments of the present application, the position regulating portion includes a first position regulating projection, and along the first direction, the first sealing member is closer to the first end wall than the first position regulating projection.

[0036] In the above technical solution, the position regulating portion may include a first position regulating projection. By positioning the first position regulating projection further from the first end than the first sealing member, the gravitational force of the first sealing member can be effectively overcome, and the displacement of the first sealing member can be restricted. This reduces the risk of loss of sealing effect between the first and second sealing surfaces due to misalignment of the first sealing member during housing assembly, resulting in a highly reliable housing and, consequently, improved battery reliability.

[0037] According to some embodiments of the present application, along the third direction, the first position regulating projection extends from one end to the other of the second sealing surface, and the third, first, and second directions are perpendicular to each other.

[0038] In the above technical solution, by extending the first position-regulating projection along the third direction and extending from one end to the other end of the second sealing surface, the displacement of any point in the third direction of the first sealing member can be effectively restricted, reducing the risk of loss of sealing effect of the first and second sealing surfaces due to misalignment of the first sealing member during housing assembly, resulting in a highly reliable housing and, consequently, improved battery reliability.

[0039] According to some embodiments of the present application, the position regulating portion further includes a second position regulating projection, and the first position regulating projection and the second position regulating projection are provided opposite to each other and spaced apart along the first direction, and the first sealing member is positioned between the first position regulating projection and the second position regulating projection.

[0040] In the above technical solution, by providing a second position-regulating projection and positioning it opposite the first position-regulating projection in the first direction with a gap between them, the displacement of the first sealing member in the first direction can be effectively restricted. This reduces the risk of loss of sealing effect between the first and second sealing surfaces due to misalignment of the first sealing member during housing assembly, resulting in a highly reliable housing and, consequently, improved battery reliability.

[0041] According to some embodiments of the present application, along the third direction, the second position regulating projection extends from one end to the other of the second sealing surface, and the third, first, and second directions are perpendicular to each other.

[0042] In the above technical solution, by extending the second position-regulating projection along the third direction and extending from one end to the other end of the second sealing surface, the displacement of any point in the third direction of the first sealing member can be effectively restricted. This reduces the risk of loss of sealing effect between the first and second sealing surfaces due to misalignment of the first sealing member during housing assembly, resulting in a highly reliable housing and, consequently, improved battery reliability.

[0043] In some embodiments of the present application, there are two first side walls, which are arranged opposite each other along a second direction. A second end wall is located between the two first side walls, and the second housing has two second sealing surfaces arranged opposite each other along the second direction, with each second sealing surface corresponding one-to-one with a first side wall.

[0044] In the above technical solution, a first sealing surface and a second sealing surface are provided on both sides of the housing along the second direction. That is, the first housing and the second housing are connected by the corresponding first sealing surface and second sealing surface on both sides in the second direction. The connection between the first housing and the second housing can be achieved without providing a flange structure protruding along the second direction on either side of the housing. This increases the space utilization rate of the battery in the second direction, making it possible to accommodate more battery cells or reduce the volume of the battery, and consequently improve the volumetric energy density of the battery.

[0045] According to some embodiments of the present invention, openings are formed at both ends of the first housing along the third direction, and the first, second, and third directions are perpendicular to each other. The second housing further includes two second side walls, which are spaced apart and facing each other in the third direction, and are connected to a second end wall, with each of the two second side walls sealing two openings.

[0046] In the above technical solution, by providing a second side wall, on the one hand, components such as explosion-proof valves, water cooling connectors, or high / low pressure plugs can be attached to the second side wall, and normal charging and discharging operation of the battery can be achieved. On the other hand, compared to the case in which a flange structure protruding in a third direction is provided between the first housing and the second housing, two By providing side walls and sealing the opening, the space utilization rate of the battery in the third direction can be increased, and the volumetric energy density of the battery can be improved.

[0047] According to some embodiments of the present application, the housing further includes a second sealing member, the second side wall having a third sealing surface, the first housing having a fourth sealing surface, and the second sealing member provided between the third sealing surface and the fourth sealing surface to seal and connect the third sealing surface and the fourth sealing surface.

[0048] In the above technical solution, by providing a second sealing member between the third sealing surface and the fourth sealing surface, the sealing performance between the second side wall and the first housing can be improved, thereby improving the sealing performance of the housing and enabling the battery to have high reliability.

[0049] According to some embodiments of the present invention, both ends of the first sealing member are connected to two second sealing members.

[0050] In the above technical solution, the first sealing member and the second sealing member may be integrally molded, or they may be connected as separate components. By providing the first sealing member and the second sealing member, good sealing performance can be provided between the first housing and the second housing, thereby improving the reliability of the battery.

[0051] According to a second aspect, several embodiments of the present application further provide a battery, comprising a battery cell and a housing according to any one of the first aspects, wherein the battery cell is housed within the housing.

[0052] In the above technical solution, by providing a position regulating portion on the second sealing surface inside the housing to regulate the position of the first sealing member, the housing has good sealing properties, the battery cells inside the housing can be effectively protected, and the battery has high reliability.

For example, they may be fixed connections, removable connections, or integral connections. They may be mechanical connections or electrical connections. They may be directly connected, indirectly connected via an intermediate medium, or be internal communication between two elements or an interaction relationship between two elements. Those skilled in the art will be able to understand the specific meaning of the above terms in the embodiments of this application depending on the specific circumstances.

[0066] The battery as referred to in the embodiments of this application refers to a single physical module comprising one or more battery cells to provide higher voltage and capacity. For example, the battery referred to in this application may comprise one or more battery cells. The battery further comprises a housing, which comprises a first housing and a second housing, the first and second housings connected together to enclose a sealed space, and the battery cells are arranged within this sealed space. To enhance the reliability of the battery and reduce the risk of liquid or other foreign matter entering the housing and damaging the battery cells, a first sealing member may be further provided between the first and second housings. For example, the first sealing member may be provided between a first sealing surface of the first housing and a second sealing surface of the second housing, and the elastic or plastic deformation of the first sealing member may fill in any uneven or non-flat areas on the first and second sealing surfaces, thereby achieving a sealed connection between the first and second sealing surfaces.

[0067] The development of battery technology requires the simultaneous consideration of various design elements, such as performance parameters including battery life, energy density, discharge capacity, and charge / discharge rate. Battery reliability also needs to be considered. In the battery assembly process, the first sealing member is first placed on the second sealing surface of the second housing, then the first housing is placed on the second housing, and then bolts are passed through through holes in the first housing and the first sealing member to connect the second housing. However, because the first sealing member is placed directly on the second sealing surface, it is susceptible to displacement due to gravity or other external impacts before the bolts are fastened to connect the first and second housings. As a result, an effective seal is not formed between the first and second sealing members, which ultimately affects the reliability of the battery.

[0068] In view of this, several embodiments of the present invention provide a housing to solve the problem that the first sealing member is displaced by gravity or other external impacts, resulting in an inability to form an effective seal between the first housing and the second housing, which affects the reliability of the battery. The housing includes a first housing, a second housing, and a first sealing member. A position regulating portion is provided as a protrusion on the second sealing surface of the second housing, thereby restricting the movement of the first sealing member.

[0069] In the above technical solution, by providing a position-regulating portion on the second sealing surface, the movement of the first sealing member due to gravity or other impacts can be effectively suppressed, reducing the risk of loss of the sealing effect between the first and second sealing surfaces due to displacement of the first sealing member. As a result, the housing has high reliability, and consequently, the reliability of the battery can be improved.

[0070] The housing according to the embodiment of the present invention is applied to a battery and includes, but is not limited to, a structure for housing other workpieces or components within the housing.

[0071] The battery according to the embodiment of this application may be used in power consumption devices such as vehicles, ships, or aircraft, but is not limited thereto.

[0072] Embodiments of the present invention provide a power consumption device powered by a battery, which may be, but is not limited to, a mobile phone, tablet PC, laptop computer, electric toy, power tool, electric bicycle, electric motorcycle, electric vehicle, ship, large truck, bus, spacecraft, etc. Electric toys may include, for example, fixed or mobile electric toys such as game consoles, electric car toys, electric boat toys and electric aircraft toys, and spacecraft may include aircraft, rockets, space shuttles and spacecraft, etc.

[0073] In the following embodiments, for the sake of explanation, the power consumption device of the embodiment of the present application will be described as a vehicle 1000.

[0074] Please refer to Figure 1. Figure 1 is a schematic diagram of a vehicle according to several embodiments of the present invention. The vehicle 1000 may be a gasoline vehicle, a natural gas vehicle, or a new energy vehicle, and the new energy vehicle may be a pure electric vehicle, a hybrid vehicle, or a range extender vehicle, etc. The type of vehicle 1000 may be a passenger car, an off-road vehicle, a heavy truck, or a bus, etc. A battery 2000 is provided inside the vehicle 1000, and the battery 2000 may be located at the bottom, front, or rear of the vehicle 1000. The battery 2000 is used to supply power to the vehicle 1000, and for example, the battery 2000 can be used as the operating power source for the vehicle 1000's circuit system, for example, to meet the power requirements for starting the vehicle 1000, navigation, and driving.

[0075] The vehicle 1000 may further include a controller 200 and a motor 300, the controller 200 being used to control the battery 2000 to supply power to the motor 300, for example, to meet the power requirements for starting, navigating, and driving the vehicle 1000.

[0076] In some embodiments of the present invention, the battery 2000 can provide driving power to the vehicle 1000 not only as an operating power source for the vehicle 1000, but also as a driving power source for the vehicle 1000, by substituting or partially substituting fuel or natural gas.

[0077] Please refer to Figure 2. Figure 2 is a schematic diagram of the internal structure of a battery 2000 according to some embodiments of the present invention. The battery 2000 includes a housing 100 and a battery cell 2001, the battery cell 2001 being housed within the housing 100. Here, the housing 100 is intended to provide a sealed space 100a for the battery cell 2001, thereby reducing the risk of liquid or other foreign matter entering the housing 100 and damaging the battery cell 2001.

[0078] In the battery 2000, there may be multiple battery cells 2001, and the multiple battery cells 2001 can be connected in series, in parallel, or in series-parallel. Series-parallel connection means that the multiple battery cells 2001 can be connected in both series and parallel. Multiple battery cells 2001 can be directly connected in series, in parallel, or in series-parallel, and then the entire assembly composed of multiple battery cells 2001 can be housed in the housing 100. Alternatively, the battery 2000 may first be formed in the form of a battery module by connecting multiple battery cells 2001 in series, in parallel, or in series-parallel, and then the multiple battery modules may be further connected in series, in parallel, or in series-parallel to form a single unit which can then be housed in the housing 100. The battery 2000 may further include other structures, such as bus members for realizing electrical connections between multiple battery cells 2001.

[0079] Each battery cell 2001 may be a secondary battery cell or a primary battery cell, and may be, but is not limited to, a lithium-sulfur battery cell, a sodium-ion battery cell, or a magnesium-ion battery cell. The battery cell 2001 may be cylindrical, flattened, rectangular, or have other shapes.

[0080] According to several embodiments of the present application, a housing 100 is provided which can be applied to a battery 2000. Please refer to Figures 3 to 5. Figure 3 is a perspective view of the housing 100 according to several embodiments of the present application, Figure 4 is an exploded view of the housing 100 according to several embodiments of the present application, and Figure 5 is an internal schematic diagram of the local structure of the housing 100 according to several embodiments of the present application.

[0081] The housing 100 includes a first housing 10, a second housing 20, a first sealing member 30, and a position regulating part 40. The first housing 10 has a first sealing surface 11. The second housing 20 has a second sealing surface 21. The first sealing member 30 is provided between the first sealing surface 11 and the second sealing surface 21, thereby sealing the first sealing surface 11 and the second sealing surface 21 together. The position regulating part 40 is provided protruding from the second sealing surface 21 and is for restricting the movement of the first sealing member 30.

[0082] In some embodiments, the first housing 10 and the second housing 20 are interconnected, forming a sealed space 100a for housing the battery cell 2001. In some embodiments, the first housing 10 can be considered as the upper housing of the battery 2000, i.e., in the direction of gravity, the first housing 10 is located above the second housing 20. The second housing 20 can be considered as the lower housing of the battery 2000, i.e., in the direction of gravity, the second housing 20 is located below the first housing 10. .stomach In some embodiments, two cabinet 20 The material can be anything from copper, iron, aluminum, stainless steel, aluminum alloy, or plastic. In some embodiments, the materials of the first housing 10 and the second housing 20 may be the same or different.

[0083] The first sealing surface 11 is a surface of the first housing 10 that seals and connects with the second sealing surface 21 of the second housing 20 to form a sealed space 100a. The second sealing surface 21 is a surface of the second housing 20 that seals and connects with the first sealing surface 11 of the first housing 10 to form a sealed space 100a.

[0084] The first sealing member 30 is provided between the first sealing surface 11 and the second sealing surface 21. The first sealing member 30 undergoes elastic or plastic deformation upon receiving a load, filling in any uneven or non-flat areas on the first sealing surface 11 and the second sealing surface 21, thereby achieving a sealed connection between the first sealing surface 11 and the second sealing surface 21. In some embodiments, the material of the first sealing member 30 may be a material that can undergo plastic or elastic deformation, such as plastic or rubber. In some embodiments, the first sealing member 30 may be in the form of a sheet, for example, a first sealing gasket.

[0085] In some embodiments, the first sealing member 30 is provided between the first sealing surface 11 and the second sealing surface 21, and the first sealing surface 11 and the second sealing surface 21 are connected to each other by means of adhesion, welding or bolting, thereby causing the first sealing member 30 to plastically or elastically deform and achieve a sealing connection between the first sealing surface 11 and the second sealing surface 21.

[0086] The position regulating portion 40 is provided on the second sealing surface 21 and is a member that protrudes from the second sealing surface 21 in a direction toward the first sealing surface 11.

[0087] In some embodiments, the position regulating portion 40 may be formed integrally with the second housing 20 by molding. In other embodiments, the position regulating portion 40 may be provided on the second sealing surface 21 after the manufacturing of the second housing 20 is completed by bonding, welding, or bolting.

[0088] In the above technical solution, by providing a position regulating portion 40 protruding from the second sealing surface 21, the movement of the first sealing member 30 can be effectively restricted, reducing the risk of loss of the sealing effect between the first sealing surface 11 and the second sealing surface 21 due to misalignment of the first sealing member 30 during the assembly of the housing 100. As a result, the housing 100 has high reliability, and consequently, the reliability of the battery 2000 can be improved.

[0089] For some embodiments of the present application, please refer to Figures 5 and 6. Figure 6 is a schematic diagram of the local structure of the second housing 20 according to some embodiments of the present application. The position regulating portion 40 includes a first position regulating projection 41 and a second position regulating projection 42 provided at intervals, and the first sealing member 30 is positioned between the first position regulating projection 41 and the second position regulating projection 42.

[0090] The first position regulating projection 41 and the second position regulating projection 42 are both provided on the second sealing surface 21, and both project from the second sealing surface 21 in the direction toward the first sealing surface 11. The first position regulating projection 41 and the second position regulating projection 42 are provided spaced apart from each other, and the first sealing member 30 may be positioned between the first position regulating member and the second position regulating member.

[0091] In the above technical solution, by providing a first position regulating projection 41 and a second position regulating projection 42 spaced apart from each other on the second sealing surface 21, and positioning the first position regulating projection 41 and the second position regulating projection 42 on both sides of the first sealing member 30, the movement of the first sealing member 30 can be effectively restricted, the first sealing member 30 can be held in the correct position, the risk of loss of sealing effect between the first sealing surface 11 and the second sealing surface 21 due to misalignment of the first sealing member 30 during assembly of the housing 100 can be reduced, the housing 100 can have high reliability, and consequently the reliability of the battery 2000 can be improved.

[0092] For some embodiments of the present application, please refer to Figure 7. Figure 7 is a schematic diagram of the first sealing member 30 according to some embodiments of the present application.

[0093] Let b be the width of the first sealing member 30 in its natural state. Let B be the minimum distance between the first position regulating projection 41 and the second position regulating projection 42 along the direction of spacing between them, satisfying b+2mm ≤ B ≤ b+20mm.

[0094] "Let b be the width of the first sealing member 30 in its natural state" means that the width dimension of the first sealing member 30 when it is not subjected to external force is b. The width direction of the first sealing member 30 may be perpendicular to the thickness direction of the first sealing member 30, or it may be perpendicular to the length direction of the first sealing member 30. The width direction of the first sealing member 30 may be the direction of the distance between the first position regulating projection 41 and the second position regulating projection 42, or the direction in which the first position regulating projection 41 is directed toward the second position regulating projection 42, or the direction in which the second position regulating projection 42 is directed toward the first position regulating projection 41.

[0095] In some embodiments, the minimum distance B between the first position regulating projection 41 and the second position regulating projection 42 may be any of the following values: b+2mm, b+3mm, b+4mm, b+5mm, b+6mm...b+18mm, b+19mm, or b+20mm, or any value between two adjacent values.

[0096] When assembling the housing 100, the first housing 10 and the second housing 20 are connected to each other, and the first sealing member 30 located between the first sealing surface 11 and the second sealing surface 21 is compressed. That is, the first sealing member 30, which is in its natural state, is deformed and compressed by the forces acting from the first housing 10 and the second housing 20, and the width of the first sealing member 30 increases. By limiting the numerical relationship between the minimum distance B between the first position regulating projection 41 and the second position regulating projection 42 and the width b of the first sealing member 30 in its natural state, the above technical solution effectively reduces the risk that the first sealing member 30 will interfere with the position regulating part 40 after compression, resulting in damage to the first sealing member 30 and a decrease in the sealing effect. As a result, the housing 100 can have high reliability, and consequently, the battery 2000 can have high reliability.

[0097] According to some embodiments of the present application, the thickness of the first sealing member 30 in its natural state is h. The height at which the position regulating portion 40 protrudes from the second sealing surface 21 is H1, satisfying 0.3h ≤ H1 ≤ 0.7h.

[0098] "Let h be the thickness of the first sealing member 30 in its natural state" means that the thickness dimension of the first sealing member 30 when it is not subjected to external force is h. The thickness direction of the first sealing member 30 may be perpendicular to the width direction of the first sealing member 30, or it may be perpendicular to the length direction of the first sealing member 30. The thickness direction of the first sealing member 30 may be perpendicular to the plane on which the second sealing surface 21 is located, or it may be the direction in which the second sealing surface 21 is directed toward the first sealing surface 11.

[0099] The statement "H1 is the height at which the position regulating portion 40 protrudes from the second sealing surface 21" can be understood as meaning that H1 is the dimension of the position regulating portion 40 along the thickness direction of the sealing member.

[0100] In some embodiments, the height H1 at which the position regulating portion 40 protrudes from the second sealing surface 21 may be any of the values ​​0.3h, 0.4h, 0.5h, 0.6h, or 0.7h, or any value between two adjacent numbers.

[0101] When assembling the housing 100, the first housing 10 and the second housing 20 are connected to each other, and the first sealing member 30, located between the first sealing surface 11 and the second sealing surface 21, is compressed. That is, the first sealing member 30, in its natural state, is deformed and compressed by the forces acting from the first housing 10 and the second housing 20, and the height of the first sealing member 30 decreases. According to the above technical solution, by limiting the numerical relationship between the height H1 to which the position regulating portion 40 protrudes from the second sealing surface 21 and the thickness h of the first sealing member 30 in its natural state, the height of the first sealing member 30 decreases after compression, and as a result the position regulating portion 40 interferes with the first sealing surface 11, the risk of damage to the first sealing surface 11 and a decrease in the sealing effect can be effectively reduced, the housing 100 can have high reliability, and consequently the battery 2000 can have high reliability.

[0102] For some embodiments of the present invention, please refer to Figure 5. The housing 100 further includes a connecting member 50, and the first sealing surface 11 and the second sealing surface 21 are connected by the connecting member 50.

[0103] The connecting member 50 may be a member for connecting the first sealing surface 11 and the second sealing surface 21. In some embodiments, the connecting member 50 may be a bolt, screw, or rivet. In some other embodiments, the connecting member 50 may be an adhesive member provided between the first sealing surface 11 and the second sealing surface 21, for example, an adhesive provided between the first sealing surface 11 and the second sealing surface 21.

[0104] In the above technical solution, by providing a connecting member 50 that connects the first sealing surface 11 and the second sealing surface 21, the sealing effect of the first sealing surface 11 and the second sealing surface 21 can be effectively enhanced, improving the connection stability between the first sealing surface 11 and the second sealing surface 21, thereby increasing the structural stability of the housing 100, and enabling the battery 2000 to have high reliability.

[0105] According to some embodiments of the present invention, the projection of the connecting member 50 along a direction perpendicular to the second sealing surface 21 does not overlap with the projection of the first sealing member 30.

[0106] "The direction perpendicular to the second sealing surface 21" may be understood as the thickness direction of the first sealing member 30, or as the direction in which the first sealing surface 11 faces the second sealing surface 21.

[0107] "The projection of the connecting member 50 does not overlap with the projection of the first sealing member 30" means that on the second sealing surface 21, the positions of the connecting member 50 and the first sealing member 30 are offset from each other so that they do not interfere with each other. For example, on the second sealing surface 21, the connecting member 50 is located on one side of the first sealing member 30.

[0108] In the above technical solution, by positioning the first sealing member 30 and the connecting member 50 offset from each other on the second sealing member 31, they do not interfere with each other, and the interference that the connecting member 50 causes to the first sealing member 30 can be reduced. As a result, the first sealing member 30 can exert an effective sealing effect between the first sealing surface 11 and the second sealing surface 21, and the risk of the first sealing member 30 being damaged and unable to provide a seal due to the connecting member 50 penetrating the first sealing member 30 can be reduced.

[0109] According to some embodiments of the present invention, the first housing 10 and the second housing 20 jointly enclose a sealed space 100a for housing a battery cell 2001. The second sealing surface 21 has a first edge 210 that is close to the sealed space 100a and a second edge 211 that is further away from the sealed space 100a, and the first sealing member 30 is closer to the first edge 210 than the connecting member 50.

[0110] For some embodiments of the present application, please refer to Figures 5 and 8. Figure 8 is an enlarged view of part A in Figure 4. The first housing 10 and the second housing 20 jointly enclose a sealed space 100a for housing the battery cell 2001. The second sealing surface 21 has a first edge 210 that is close to the sealed space 100a and a second edge 211 that is further away from the sealed space 100a, and the first sealing member 30 is closer to the first edge 210 than the connecting member 50.

[0111] The sealed space 100a may be a space jointly enclosed by the first housing 10 and the second housing 20. The battery cells 2001 of the battery 2000 are housed within the sealed space 100a.

[0112] "First edge 210" refers to the edge of the second sealing surface 21 that is close to the sealed space 100a, and can be considered the "inner edge" of the second sealing surface 21. "Second edge 211" refers to the edge of the second sealing surface 21 that is farther from the sealed space 100a, and can be considered the "outer edge" of the second sealing surface 21. "The first sealing member 30 is closer to the first edge 210 than the connecting member 50" can be understood as the first sealing member 30 being closer to the sealed space 100a than the connecting member 50, that is, being located inside the second sealing surface 21 than the connecting member 50. In some embodiments, when an external liquid enters the sealed space 100a from outside the housing 100, the liquid first passes over the location of the connecting member 50, and then passes over the location of the first sealing member 30.

[0113] In the above technical solution, the first edge 210 of the second sealing surface 21 is closer to the sealed space 100a than the second edge 211, that is, the side of the second sealing surface 21 away from the second edge 211 can be considered the inside, and the side of the second sealing surface 21 away from the first edge 210 can be considered the outside. Therefore, the first sealing member 30 is closer to the first edge 210 than the connecting member 50. It can be understood that the first sealing member 30 is located inside the connecting member 50. By positioning the first sealing member 30 inside the connecting member 50, even after the connecting member 50 is damaged and the connection is lost, the first sealing member 30 can still exert a certain sealing effect, the housing 100 can have high reliability, and consequently the battery 2000 can have high reliability.

[0114] For some embodiments of the present application, please refer to Figures 5, 6, and 8. A through hole 110 is formed in the first sealing surface 11, and a threaded hole 212 is formed in the second sealing surface 21. The connecting member 50 passes through the through hole 110 and is screw-fitted into the threaded hole 212.

[0115] "A through hole 110 is formed in the first sealing surface 11" means that a through hole 110 is formed in the first housing 10 at the location of the first sealing surface 11, and the connecting member 50 is inserted through the through hole 110. "A screw hole 212 is formed in the second sealing surface 21" means that a screw hole 212 is formed in the second housing 20 at the location of the second sealing surface 21, and the opening of the screw hole 212 is located on the second sealing surface 21.

[0116] In some embodiments, the connecting member 50 may be a screw-type fastening member, that is, an external thread is formed on at least a portion of the circumferential surface of the connecting member 50, and it engages with the screw hole 212.

[0117] In the above technical solution, by providing a through hole 110 in the first sealing surface 11 and a screw hole 212 in the second sealing surface 21, the connecting member 50 can effectively connect the first sealing surface 11 and the second sealing surface 21 using a screw connection method, thereby improving the sealing effect of the first sealing surface 11 and the second sealing surface 21, as well as the connection stability between them. As a result, the housing 100 can have high reliability, and the battery 2000 can have high reliability.

[0118] According to some embodiments of the present invention, the connecting member 50 includes a main body 51 and a first position regulating body 52, one end of the main body 51 is connected to the first position regulating body 52, and the other end of the main body 51 is screw-fitted with a screw hole 212. The cross-sectional area of ​​the first position regulating body 52 is larger than the cross-sectional area of ​​the main body 51, and the first position regulating body 52 is in contact with a surface of the first housing 10 that is separated from the second sealing surface 21.

[0119] In some embodiments, the main body 51 may be the main part of the connecting member 50. External threads may be formed on at least a portion of the circumferential surface of the main body, allowing it to be screw-fitted with the screw holes 212. The first position regulating body 52 may be connected to one end of the main body 51 and may be structured to abut the location where the first sealing surface 11 of the first housing 10 is located. In some embodiments, the main body 51 may be rod-shaped, and the first position regulating body 52 is provided at one end of the main body 51. In some embodiments, the axial direction of the main body 51 may be parallel to the direction in which the first sealing surface 11 faces the second sealing surface 21.

[0120] The cross-sectional area of ​​the first position restrictor 52 is the projected area of ​​the first position restrictor 52 onto the surface perpendicular to the axial direction of the main body 51. And, Alternatively, it is the cross-sectional area of ​​the first position restrictor 52 on the surface perpendicular to the axial direction of the main body 51. It can be understood as such. The cross-sectional area of ​​the main body 51 is the projected area of ​​the main body 51 onto a surface perpendicular to the axial direction of the main body 51. And, Alternatively, it is the cross-sectional area of ​​the main body 51 on a surface perpendicular to the axial direction of the main body 51. It can be understood as such. .

[0121] In the above technical solution, the connecting member 50 includes a main body 51 and a first position restrictor 52. By setting the cross-sectional area of ​​the first position restrictor 52 to be larger than the cross-sectional area of ​​the main body 51, the surface of the first housing 10 that moves away from the second sealing surface 21 can be effectively restrained, improving the connection stability between the first sealing surface 11 and the second sealing surface 21, and enhancing the structural stability of the housing 100.

[0122] According to some embodiments of the present invention, the connecting member 50 further includes a second position restrictor 53, which is provided between the first position restrictor 52 and the main body 51, the cross-sectional area of ​​the first position restrictor 52 being larger than the cross-sectional area of ​​the second position restrictor 53, and the cross-sectional area of ​​the second position restrictor 53 being larger than the cross-sectional area of ​​the main body 51. A portion of the second position restrictor 53 is located within the through hole 110 and is in contact with the second sealing surface 21.

[0123] The second position restrictor 53 is located between the first position restrictor 52 and the main body 51. On the surface of the main body 51 perpendicular to the axial direction, the projected area of ​​the second position restrictor 53 is smaller than the projected area of ​​the first position restrictor 52, and the projected area of ​​the second position restrictor 53 is larger than the projected area of ​​the main body 51.

[0124] In some embodiments, when assembling the connecting member 50, the second position regulating body 53 may pass through the through hole 110 of the first sealing surface 11. When the assembly of the connecting member 50 is complete, a portion of the second position regulating body 53 may be located within the through hole 110 and in contact with the second sealing surface 21.

[0125] In the above technical solution, a second position restrictor 53 is provided between the first position restrictor 52 and the main body 51, and the cross-sectional area of ​​the second position restrictor 53 is set to be smaller than the cross-sectional area of ​​the first position restrictor 52 and larger than the cross-sectional area of ​​the main body 51. This causes the end face of the second position restrictor 53 that is separated from the first position restrictor 52 to contact the second sealing surface 21, thereby restricting the depth of screw engagement with the screw hole 212 of the main body 51. This restricts the degree of compression of the first sealing member 30, reducing the problem of excessive load acting on the first sealing member 30 due to excessive screw engagement depth, which can cause damage and loss of sealing effect. On the other hand, it reduces the risk that the first sealing member 30 will not perform its sealing function or will have an insufficient sealing effect due to insufficient screw engagement depth.

[0126] In some embodiments, a plurality of connecting members 50 can be provided along the extending direction of the second sealing surface 21, and the plurality of connecting members 50 are arranged at intervals from one another.

[0127] For some embodiments of the present application, please refer to Figures 4 and 5. The first housing 10 includes a first side wall 12, a through hole 110 is formed in the first side wall 12, and the first position regulating body 52 is in contact with the surface of the first side wall 12 that is away from the second sealing surface 21. Let h be the thickness of the first sealing member 30 in its natural state, d be the thickness of the first side wall 12, and H2 be the length of the second position regulating body 53, satisfying 0.3h+d≦H2≦0.7h+d.

[0128] The first side wall 12 is part of the structure of the first housing 10. The first sealing surface 11 is provided on the first side wall 12. The statement "the first position restrictor 52 contacts the surface of the first side wall 12 that is separated from the second sealing surface 21" can be understood to mean that the first position restrictor 52 of the connecting member 50 abuts against the first side wall 12, restraining the first side wall 12, and that the first side wall 12 is effectively connected to the second sealing surface 21 of the second housing 20.

[0129] "Let h be the thickness of the first sealing member 30 in its natural state" means that the thickness dimension of the first sealing member 30 when it is not subjected to external force is h. The thickness direction of the first sealing member 30 may be perpendicular to the width direction of the first sealing member 30, or it may be perpendicular to the length direction of the first sealing member 30. The thickness direction of the first sealing member 30 may be perpendicular to the plane on which the second sealing surface 21 is located, or it may be the direction in which the second sealing surface 21 is directed toward the first sealing surface 11.

[0130] "Let the thickness of the first side wall 12 be d" can be understood as the dimension of the first side wall 12 in the thickness direction of the first sealing member 30 being d. "Let the length of the second position regulating body 53 be H2" can be understood as the dimension of the second position regulating body 53 in the thickness direction of the first sealing member 30 being H2 It can be understood that this is the case.

[0131] In some embodiments, the length H2 of the second position restrictor 53 may be any of the following values: 0.3h+d, 0.4h+d, 0.5h+d, 0.6h+d, or 0.7h+d, or any value between two adjacent values.

[0132] When assembling the housing 100, the first housing 10 and the second housing 20 are connected to each other, and the first sealing member 30 located between the first sealing surface 11 and the second sealing surface 21 is compressed. That is, the first sealing member 30 in its natural state is deformed and compressed by the forces acting from the first housing 10 and the second housing 20, and the height of the first sealing member 30 decreases. According to the above technical solution, by limiting the numerical relationship between the thickness d of the first side wall 12, the length H2 of the second position regulating body 53, and the thickness h of the first sealing member 30 in its natural state, the compression ratio in the thickness direction of the first sealing member 30 can be effectively controlled. On the one hand, the problem of excessive load acting on the first sealing member 30 due to an excessive screw engagement depth, causing damage and loss of sealing effect, can be reduced. On the other hand, the risk of the compression ratio in the thickness direction of the first sealing member 30 being inappropriate due to an insufficient screw engagement depth, resulting in no sealing function or insufficient sealing effect, can be reduced. Furthermore, by controlling the compression ratio in the thickness direction of the first sealing member 30, the risk of excessive reaction force associated with screw fitting causing damage to the first side wall 12 can be reduced, thereby giving the housing 100 high reliability, and consequently, the battery 2000 high reliability.

[0133] According to some embodiments of the present application, the first sealing surface 11 and the second sealing surface 21 intersect with the horizontal plane.

[0134] In some embodiments, under normal operating conditions of the battery 2000, both the first sealing surface 11 and the second sealing surface 21 intersect with a horizontal plane. The horizontal plane may be a surface perpendicular to the vertical direction.

[0135] In the above technical solution, the horizontal plane is a plane perpendicular to the vertical direction (in some embodiments, the vertical direction may be parallel to the direction of gravity), and if the first sealing surface 11 and the second sealing surface 21 are limited to intersecting the horizontal plane, there is a risk that the first sealing member 30 will slide relative to the second sealing surface 21 due to the influence of gravity when it is installed on the second sealing surface 21. In contrast, by providing a position regulating portion 40 protruding on the second sealing surface 21, the displacement of the first sealing member 30 due to the influence of gravity can be effectively restricted, reducing the risk that the sealing effect of the first sealing surface 11 and the second sealing surface 21 will be lost due to the misalignment of the first sealing member 30 during the assembly of the housing 100, thereby giving the housing 100 high reliability and, consequently, improving the reliability of the battery 2000.

[0136] According to some embodiments of the present application, the first sealing surface 11 and the second sealing surface 21 are provided perpendicular to the horizontal plane.

[0137] The statement "The first sealing surface 11 and the second sealing surface 21 are provided perpendicular to the horizontal plane" can be understood as meaning that, in the normal operating state of the battery 2000, both the first sealing surface 11 and the second sealing surface 21 are perpendicular to the horizontal plane, for example, both the first sealing surface 11 and the second sealing surface 21 are parallel to the upright direction. In some embodiments, the first sealing surface 11 and the second sealing surface 21 may be referred to as "vertical surfaces".

[0138] In the above technical solution, by making the first sealing surface 11 and the second sealing surface 21 perpendicular to the horizontal plane, on the one hand, the space occupied horizontally by the connection between the first housing 10 and the second housing 20 can be saved, and the space occupied by the housing 100 can be reduced. On the other hand, by providing a position regulating portion 40 protruding on the second sealing surface 21, the gravity of the first sealing member 30 can be effectively overcome and the first sealing member 30 can be held in the correct position, reducing the risk that the sealing effect of the first sealing surface 11 and the second sealing surface 21 will be lost due to misalignment of the first sealing member 30 during the assembly of the housing 100, thereby giving the housing 100 high reliability and, consequently, improving the reliability of the battery 2000.
