Description

Technical Field

[0001] Embodiments of the present application relate to the field of batteries, and more specifically, to battery cases, batteries, brackets, and power-consuming devices.

Background Art

[0002] Energy conservation and emission reduction are crucial for the sustainable development of the automotive industry. In such a context, electric vehicles have become an important component of the sustainable development of the automotive industry due to their energy-saving and environmentally friendly advantages. However, for electric vehicles, battery technology is an important factor related to their development.

[0003] In the development of battery technology, in addition to improving the performance of the battery itself, the mounting stability of the battery is also a problem that cannot be ignored. Therefore, how to strengthen the mounting stability of the battery has become a technical problem that urgently needs to be solved in battery technology.

Summary of the Invention

[0004] The present application provides a battery case, a battery, a bracket, and a power-consuming device capable of enhancing the mounting stability of the battery.

[0005] In a first aspect, there is provided a battery case including a case body for accommodating battery cells, and a first stopper disposed on one side of the first wall of the case body away from the battery cells, wherein the first wall is perpendicular to a first direction, the first direction is parallel to the traveling direction of the power-consuming device after the case is attached to the power-consuming device, and the first stopper is for restricting the relative displacement of the case along the first direction.

[0006] According to the technical solution of the embodiment of the present application, a first stopper is installed on one side of the first wall of the case body away from the battery cell, and the first wall is perpendicular to the first direction. After the case is attached to the power consumption device, the first direction is parallel to the travel direction of the power consumption device. Therefore, after the case is attached to the power consumption device, the first stopper can generate an acting force on the power consumption device along the first direction, that is, the first stopper can generate an acting force on the power consumption device along the travel direction and the opposite travel direction of the power consumption device. This limits the relative displacement of the case along the travel direction and the opposite travel direction of the power consumption device, improves the mounting stability of the case along the travel direction and the opposite travel direction of the power consumption device, reduces the influence of the power consumption device in motion on the battery and its case, and ensures the normal operation of the battery and the power consumption device in which it is located.

[0007] In some possible embodiments, the case further includes a second stopper installed on one side of the case body away from the battery cell and used to limit relative displacement along a second direction of the case, wherein the second direction is parallel to the direction of gravity after the case is attached to the power consumption device.

[0008] According to the technical solution of this embodiment, a second stopper is installed on one side of the case body away from the battery cell, and after the case is attached to the power consumption device, the second stopper can generate a force acting on the power consumption device along a second direction, that is, the second stopper can generate a force acting on the power consumption device along both the gravitational and anti-gravity directions, thereby limiting the relative displacement of the case along the gravitational and anti-gravity directions, further improving the mounting stability of the case to the power consumption device, and ensuring the normal operation of the battery and the power consumption device in which it is located.

[0009] In some possible embodiments, the first stopper includes a first stop block installed on the first wall and movable along the first direction, and a buffer block installed between the first stop block and the first wall and used to provide a buffer distance for the first stop block along the first direction.

[0010] According to the technical solution of this embodiment, when attaching the case to the power consumption device, the mutual cooperation of the buffer block and the first stop block allows the first stop block to move into the case along the first direction, and the first stop block does not provide excessive mounting resistance, allowing the case to be conveniently attached to the power consumption device. Furthermore, after the case is attached to the power consumption device, the first stop block compresses the buffer block, putting the buffer block into a compressed state, thereby providing an elastic force to the first stop block, which in turn presses the first stop block tightly against the power consumption device in the first direction, ensuring mounting stability of the case along the first direction, that is, ensuring mounting stability of the case along the direction of travel and the direction opposite to travel of the power consumption device.

[0011] In some possible embodiments, the first stopper further includes a first fixing member, the first stop block being installed on the first wall by the first fixing member, and the first fixing member is for providing a buffer space between the first stop block and the buffer block along the first direction.

[0012] According to the technical solution of this embodiment, the first stop block is installed on the first wall of the case body by a first fixing member, and a buffer space is provided between the first stop block and the buffer block, so that the first stop block can be displaced relative to the buffer block in a first direction, and further contributes to the mounting of the case to the power consumption device and the mounting stability of the case along the first direction.

[0013] In some possible embodiments, a wedge angle is provided at the first end of the first stop block, which is the end of the first stop block facing the anti-gravity direction.

[0014] According to the technical solution of this embodiment, when attaching the case to the power consumption device in the anti-gravity direction, the case can be gradually moved in the anti-gravity direction with the help of the first end having a wedge angle in the first stop block, and the first end can guide and position the case when attaching it to the power consumption device, making it easier to attach the case to the power consumption device.

[0015] In some possible embodiments, the second stopper is an elastic stop block, and after the case is attached to the power consumption device, the elastic stop block is compressed and comes into contact with the power consumption device.

[0016] According to the technical solution of this embodiment, by making the second stopper an elastic stop block, after the case is attached to the power consumption device, the elastic stop block is compressed and comes into contact with the power consumption device, creating an elastic force between the compressed elastic stop block and the power consumption device, and the elastic stop block is pressed tightly against the power consumption device in the second direction, ensuring mounting stability of the case along the second direction, that is, ensuring mounting stability of the case along the direction of gravity and anti-gravity of the power consumption device.

[0017] In some possible embodiments, a chamfered structure is provided on the first end of the elastic stop block, which is the end of the elastic stop block facing the anti-gravity direction.

[0018] According to the technical solution of this embodiment, when the case is attached to the power consumption device along the anti-gravity direction, the first end of the elastic stop block facing the anti-gravity direction contacts and acts on the power consumption device first. By installing a chamfered structure on the first end of the elastic stop block, the first end of the elastic stop block is easily compressed by the power consumption device. Furthermore, compared to a sharp-angled structure, the chamfered structure avoids stress concentration, extending the service life of the elastic stop block. In addition, the chamfered structure can also improve the aesthetic appearance of the elastic stop block.

[0019] In some possible embodiments, the first wall is provided with a housing area for accommodating the first stopper.

[0020] According to the technical solution of this embodiment, by providing a housing area in the first wall of the case to house the first stopper, the mounting space for the first stopper can be saved, and at the same time, the housing area can protect the first stopper so as to prevent it from being damaged by external influences and thus improve the service life of the first stopper in the case.

[0021] In some possible embodiments, the first wall includes an extension that extends away from the battery cell along the first direction and is used to install the second stopper.

[0022] In some possible embodiments, the centers of the first stopper and the second stopper are located in a first plane parallel to the plane specified in the first and second directions.

[0023] According to the technical solution of this embodiment, the centers of the first stopper and the second stopper are both on a first plane parallel to the planes specified in the first and second directions. After the case is attached to the power consumption device, the forces acting on the first stopper and the power consumption device, and the forces acting on the second stopper and the power consumption device, converge on the same plane, further improving the mounting stability of the case to the power consumption device. Furthermore, if the first stopper and the second stopper are installed adjacent to each other on the same first wall, the forces acting between the first and second stoppers and the power consumption device become even more concentrated, further improving the mounting stability of the case to the power consumption device. Also, because the first and second stoppers are installed adjacent to each other, installation and repair of the first and second stoppers become more convenient.

[0024] In some possible embodiments, the case includes a plurality of first stoppers distributed between two parallel first walls in the case body.

[0025] According to the technical solution of this embodiment, by providing a plurality of first stoppers in the space between the two first walls and distributing them among these two first walls, the first stoppers on the two first walls of the case can each generate an acting force along the first direction relative to the power consumption device. In this way, the case is tightly sandwiched between the power consumption device in the first direction, and the relative displacement of the case along the first direction relative to the power consumption device is further limited, thereby improving the mounting stability of the case to the power consumption device.

[0026] In some possible embodiments, multiple first stoppers are distributed and installed in the four corner regions of the case body.

[0027] According to the technical solution of this embodiment, the multiple first stoppers included in the case are distributed and installed in the four corner regions of the case body, thereby limiting the relative displacement of the power consumption device in the four corner regions of the case and comprehensively improving the mounting stability of the case to the power consumption device.

[0028] On the second side, there is a bracket applied to a power consumption device, including a bracket body used to attach a battery case of the power consumption device for accommodating a battery cell, and a third stopper installed on one side of the first beam of the bracket body close to the case, wherein the extending direction of the first beam is perpendicular to a first direction parallel to the traveling direction of the power consumption device, and the third stopper is for restricting the relative displacement of the case along the first direction.

[0029] According to the technical solution of the embodiment of the present application, since the third stopper is installed on one side of the first beam of the bracket body close to the battery case and the extending direction of the first beam is perpendicular to the first direction parallel to the traveling direction of the power consumption device, after the battery case is attached to the bracket body of the power consumption device, the third stopper can generate a acting force along the first direction on the case, that is, the third stopper can generate a acting force along the traveling direction and the reverse traveling direction of the power consumption device on the case. Thereby, the relative displacement of the case along the traveling direction and the reverse traveling direction of the power consumption device is restricted, the mounting stability of the case along the traveling direction and the reverse traveling direction of the power consumption device is improved, the influence of the power consumption device in the traveling state on the battery and its case is reduced, and the normal operation of the battery and the power consumption device where it is located is ensured.

[0030] In some possible embodiments, the bracket further includes a fourth stopper installed on the bracket body and used for restricting the relative displacement of the case along a second direction parallel to the gravity direction of the case.

[0031] According to the technical solution of the embodiment, by installing the fourth stopper on the bracket body, the fourth stopper can generate a acting force along the second direction on the case, that is, the fourth stopper can generate a acting force along the gravity direction and the reverse gravity direction on the case. Thereby, the relative displacement of the case along the gravity direction and the reverse gravity direction is restricted, the mounting stability of the case to the bracket is further improved, and the normal operation of the battery and the power consumption device where it is located is ensured.

[0032] In some possible embodiments, the fourth stopper includes a groove structure with an opening facing the direction of gravity.

[0033] In some possible embodiments, after the battery case is attached to the bracket body, the groove structure accommodates a second stopper for the case to limit the relative displacement of the case along the second direction.

[0034] According to the technical solution of this embodiment, the groove structure can cooperate with a second stopper in the battery case, and by accommodating the second stopper and being tightly pressed against the second stopper, the groove structure can achieve tight clamping of the case to the bracket body in a second direction, thereby improving the mounting stability of the case to the bracket body in both the direction of gravity and the direction of anti-gravity.

[0035] In some possible embodiments, the third stopper includes a third stop block having a wedge angle at one end facing the direction of gravity, and a second fixing member for fixing the third stop block to the first beam.

[0036] According to the technical solution of this embodiment, a wedge angle may be provided at one end of the third stop block facing the anti-gravity direction. When attaching the case to the bracket facing the anti-gravity direction, the end of the third stop block with the wedge angle can be used to gradually move the case in the anti-gravity direction. The end with the wedge angle can guide and position the case when attaching it to the bracket, making it easier to attach the case to the bracket.

[0037] In some possible embodiments, the centers of the third stopper and the fourth stopper are located in a first plane parallel to the planes specified in the first and second directions.

[0038] According to the technical solution of this embodiment, the centers of the third stopper and the fourth stopper are both on a first plane parallel to the planes specified in the first and second directions. After the case is attached to the bracket, the forces acting on the third stopper and the case, and the forces acting on the fourth stopper and the case, converge on the same plane, further improving the mounting stability of the case to the bracket. Furthermore, if the third stopper and the fourth stopper are installed adjacent to each other on the same first beam, the forces acting on the third and fourth stoppers and the case become even more concentrated, further improving the mounting stability of the case to the bracket. Also, because the third and fourth stoppers are installed adjacent to each other, installation and repair of the third and fourth stoppers become more convenient.

[0039] In some possible embodiments, the bracket includes a plurality of third stoppers distributed on at least two parallel first beams of the bracket body.

[0040] According to the technical solution of this embodiment, by providing a plurality of third stoppers in the space of at least two first beams and distributing them among these at least two first beams, the third stoppers on at least two first beams in the bracket body can all generate an acting force on the case along the first direction. In this way, the case is tightly sandwiched between the bracket body in the first direction, and the relative displacement of the case in the bracket along the first direction is further limited, thereby improving the mounting stability of the case to the power consumption device.

[0041] In some possible embodiments, multiple third stoppers are distributed in the four corner regions of the space in the bracket body for housing the case.

[0042] According to the technical solution of this embodiment, a plurality of third stoppers may be further distributed and installed in the four corner regions of the space for housing the case in the bracket body, and may also be installed corresponding to the four corner regions of the case. This limits the relative displacement of the bracket in the four corner regions of the case, thereby comprehensively improving the mounting stability of the case to the bracket and the power consumption device in which it is located.

[0043] The present invention provides a battery comprising a battery cell and a battery case for housing the battery cell, in a possible embodiment of the first side or the first side.

[0044] The present invention provides a power consumption device comprising, in a fourth aspect, a battery in the third aspect and a bracket in either the second aspect or in any possible embodiment of the second aspect, wherein the third stop block thereof cooperates with the first stopper of the battery to limit the relative displacement of the battery along the first direction.

[0045] A fifth aspect provides a battery manufacturing method comprising the steps of: providing a battery cell; providing a case comprising a case body for housing the battery cell; and a first stopper installed on one side of a first wall of the case body away from the battery cell, wherein the first wall is perpendicular to a first direction, and after the case is attached to a power consumption device, the first direction is parallel to the direction of travel of the power consumption device, and the first stopper is for limiting the relative displacement of the case along the first direction; and housing the battery cell in the case.

[0046] In the sixth aspect, a first supply module for providing a battery cell, A second providing module for providing a case, the case comprising a case body for housing the battery cell, and a first stopper installed on one side of the first wall of the case body away from the battery cell, wherein the first wall is perpendicular to a first direction, and after the case is attached to a power consumption device, the first direction is parallel to the direction of travel of the power consumption device, and the first stopper is for limiting the relative displacement of the case along the first direction. The present invention provides a battery manufacturing apparatus that includes a mounting module for housing the battery cell in the case.

[0047] According to the technical solution of the embodiment of the present application, a first stopper is installed on one side of the first wall of the case body away from the battery cell, and the first wall is perpendicular to the first direction. After the case is attached to the power consumption device, the first direction is parallel to the travel direction of the power consumption device. Therefore, after the case is attached to the power consumption device, the first stopper can generate an acting force on the power consumption device along the first direction x, that is, the first stopper can generate an acting force on the power consumption device along the travel direction and the opposite travel direction of the power consumption device. This limits the relative displacement of the case along the travel direction and the opposite travel direction of the power consumption device, improves the mounting stability of the case along the travel direction and the opposite travel direction of the power consumption device, reduces the influence of the power consumption device in motion on the battery and its case, and ensures the normal operation of the battery and the power consumption device in which it is located.

[0050] Embodiments of the present application will be described in more detail below with reference to the attached drawings and examples. The detailed description of the embodiments below and the attached drawings are not intended to limit the scope of the present application, but are for illustrative purposes to illustrate the principles of the present application; that is, the present application is not limited to the embodiments described.

[0051] In the description of this application, unless otherwise stated, "multiple" means two or more, and the directions or positional relationships indicated by technical terms such as "up," "down," "left," "right," "inside," and "outside" are merely for the purpose of easily describing this application and simplifying the description. The described devices or elements do not necessarily have a specific direction, or are configured or operated in a specific direction, and therefore should not be understood as limiting this application. Furthermore, technical terms such as "first," "second," and "third" are merely for the purpose of describing the purpose and should not be understood as explicitly or implicitly indicating relative importance. "Perpendicular" does not mean strictly perpendicular, but rather within the allowable margin of error. "Parallel" does not mean strictly parallel, but rather within the allowable margin of error.

[0052] The directional terms used in the following description do not limit the specific structure of this application, but all refer to the directions shown in the diagrams. As further explanation is needed in the description of this application, the terms "attachment," "connection," and "connection" should be understood broadly unless explicitly defined or limited elsewhere. For example, they may be fixedly connected, detachably connected, integrally connected, directly connected, or connected via an intermediate element. Those skilled in the art will be able to understand the specific meaning of these terms in this application based on the specific circumstances.

[0053] In this application, the term "and / or" is used solely to describe the relationship between related objects, indicating that three types of relationships are possible. For example, A and / or B represents three situations: A existing alone, A and B existing simultaneously, and B existing alone. The symbol " / " in the text generally indicates that the preceding and succeeding related objects have an "or" relationship.

[0054] All technical and scientific terms used in this application have the same meaning as those commonly understood by those skilled in the art unless otherwise defined. Terms used in the specification of this application are for the sole purpose of describing specific embodiments, without limiting the application. The terms “including,” “having,” and any variation thereof as described in the specification, claims, and accompanying drawings of this application include non-exclusive inclusion. The terms “first,” “second,” and so on in the specification, claims, and accompanying drawings of this application are for the sole purpose of distinguishing different subjects and not to describe any predetermined order or primary relationship.

[0055] Where the “Examples” are referred to in this Application, it means that certain features, configurations, or characteristics described in the Examples may be included in at least one Example of this Application. Where the term appears in the Specification, it does not necessarily refer to the same Example, nor does it mean that the Examples are independent or candidate Examples that are mutually exclusive with each other. It will be clearly and implicitly understood by those skilled in the art that the Examples described in the Text may be combined with other Examples.

[0056] In this application, the battery cell may include, but is not limited to, lithium-ion secondary batteries, lithium-ion primary batteries, lithium-sulfur batteries, sodium-lithium-ion batteries, sodium-ion batteries, or magnesium-ion batteries. The battery cell may also be cylindrical, flattened, rectangular, or have other shapes, but is not limited to, the embodiments of this application. Generally, battery cells are classified into three types based on their packaging method: columnar battery cells, rectangular parallelepiped battery cells, and pouch-type battery cells, and are not limited to, the embodiments of this application.

[0057] The battery described in the embodiments of this application represents a single physical module containing one or more battery cells to provide higher voltage and capacity. For example, the battery described in this application may include a battery module or a battery pack, etc. The battery generally includes a housing for packaging one or more battery units. The housing can prevent liquids or other foreign matter from affecting the charging or discharging of the battery cells.

[0058] Regarding the development of battery technology, it is necessary to simultaneously consider various design elements such as the energy density, cycle life, charge / discharge capacity, charge / discharge rate, and safety performance of the battery, as well as the mounting stability of the battery.

[0059] Specifically, batteries are generally installed in power consumption devices during the application process to supply electrical energy to the device. If the battery is not securely attached to the power consumption device and its stability is poor, a certain external force will be applied to the battery when the power consumption device is in motion, especially when it is in motion with acceleration. This can cause the battery to undergo relative displacement within the power consumption device, and in severe cases, it may detach from its fixed mounting position, affecting the electrical connection between the battery and the power consumption device, as well as affecting the battery's own performance. Ultimately, this can lead to abnormal operation of the power consumption device and pose a certain risk.

[0060] In view of the foregoing, the present invention provides a battery case used to house a battery cell and including a first stopper, wherein after the case is attached to the power consumption device, the first stopper is for limiting the relative displacement of the battery along the direction of travel of the power consumption device. Alternatively, the present invention may further provide a bracket for a power consumption device used to mount the battery of the power consumption device and including a third stopper, wherein after the battery case is attached to the power consumption device, the third stopper is for limiting the relative displacement of the battery along the direction of travel of the power consumption device.

[0061] In some application scenarios, power consumption devices generally generate motion along their direction of travel and may generate motion with acceleration, which can have a significant impact on the battery. By installing a first stopper on the battery case and / or a third stopper on the bracket of the power consumption device, the mounting stability of the battery to the power consumption device, especially the mounting stability along the direction of travel of the power consumption device, can be enhanced, thereby ensuring the normal operation of the battery and the power consumption device in which it is located.

[0062] The technical solutions described in the embodiments of this application are applicable to various power consumption devices that utilize batteries, such as electric vehicles, electric toys, power tools, ships, and spacecraft, for example, spacecraft include airplanes, rockets, spaceplanes, and spaceships.

[0063] It should be understood that the technical solutions described in the embodiments of this application are not limited to application to the various power consumption devices mentioned above, but are applicable to all devices or equipment that utilize batteries. For the sake of explanation, the embodiments below will all be described using electric vehicles as examples.

[0064] For example, Figure 1 shows a schematic diagram of the structure of a vehicle 1 according to one embodiment of the present invention, where the vehicle 1 may be a fuel oil 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 electric vehicle, etc. A motor 14, a controller 13, and a battery 10 may be installed inside the vehicle 1, and the controller 13 is for controlling the battery 10 to supply power to the motor 14. For example, the battery 10 can be installed at the bottom of the vehicle 1, the front of the vehicle body, or the rear of the vehicle body. The battery 10 can be used to supply power to the vehicle 1, for example, as an operating power source for the vehicle 1, and can be used for the circuit systems of the vehicle 1, for example, as the power required to start up the vehicle 1, for navigation, and to operate during driving. In another embodiment of the present invention, the battery 10 can not only be an operating power source for the vehicle 1, but can also be used as a driving power source for the vehicle 1, providing driving power to the vehicle 1 by replacing or partially replacing fuel oil or natural gas.

[0065] To accommodate different power usage requirements, a battery may contain multiple battery cells, which can be connected in series, parallel, or a mixed configuration. A mixed configuration is a combination of series and parallel connections. The battery may also be called a battery pack. Optionally, a battery module can be constructed first from multiple battery cells by series, parallel, or mixed connections, and then a battery can be constructed from these battery modules by series, parallel, or mixed connections. In other words, a battery can be constructed directly from multiple battery cells, or a battery module can be constructed first, and then a battery can be constructed from the battery module.

[0066] For example, Figure 2 shows a schematic diagram of the structure of a battery 10 according to one embodiment of the present invention, and the battery 10 may include a plurality of battery cells 100. The battery 10 may further include a case body 200 (also referred to as a housing body) which has a hollow internal structure, and the plurality of battery cells 100 are housed inside the case body 200. As shown in Figure 2, the case body 200 may include two parts, which are referred to as a first part 2100 and a second part 2200, respectively, and the first part 2100 and the second part 2200 engage integrally. The shapes of the first part 2100 and the second part 2200 can be determined according to the shape of the plurality of battery cells 100 combined, and each may have one opening. For example, the first part 2100 and the second part 2200 may both be hollow rectangular parallelepipeds, and each may have only one open surface, with the openings of the first part 2100 and the second part 2200 facing each other, and the first part 2100 and the second part 2200 engaging with each other to form a case body 200 having a closed cavity. Multiple battery cells 100 are combined by parallel, series, or mixed connections and then placed inside the case body 200 formed after the first part 2100 and the second part 2200 engage.

[0067] Optionally, the battery 10 may include other structures, which will not be described in detail here. For example, the battery 10 may further include busbars for realizing electrical connections between multiple battery cells 100, such as parallel, series, or mixed connections. Specifically, the busbars can realize electrical connections between the battery cells 100 by connecting the electrode terminals of the battery cells 100. Furthermore, the busbars can be fixed to the electrode terminals of the battery cells 100 by welding. The electrical energy of the multiple battery cells 100 can further be extracted through the case via a conductive mechanism. Optionally, the conductive mechanism may belong to the busbars.

[0068] The number of battery cells 100 can be set to any number according to different power requirements. Multiple battery cells 100 can be connected in series, parallel, or mixed configurations to achieve a large capacity or output. Since each battery 10 may contain a large number of battery cells 100, they may be grouped together for convenient installation, and each group of battery cells 100 can form a battery module. The number of battery cells 100 included in a battery module is not limited and can be set as needed.

[0069] To conveniently attach the battery 10 to the vehicle 1, Figure 3 shows a schematic diagram of the structure of a bracket body 300 installed on the vehicle 1. The battery case body 200 can be attached to the bracket body 300 to enable the attachment of the battery 10 to the vehicle 1. In some embodiments, the bracket body 300 can be installed on the chassis of the vehicle 1 to facilitate the attachment and replacement of the battery 10 installed on the bracket body 300. In other embodiments, the bracket body 300 may be installed at a different location from the battery 10, and the embodiments of this application are not limited thereto.

[0070] In the embodiment of the present invention, the bracket body 300 may include a plurality of beams, which surround and form a housing space for housing at least one of the batteries 10, specifically housing at least one case body 200 of at least one of the batteries 10, and for mounting at least one battery 10 to the vehicle 1.

[0071] Optionally, the bracket body 300 may include at least one first beam 301 and a pair of second beams 302, wherein the pair of second beams 302 are installed facing each other, and at least one first beam 301 is installed perpendicular to the extending direction of the second beams 302 and connected to the pair of second beams 302.

[0072] For example, in the embodiment shown in Figure 3, the bracket body 300 includes three first beams 301, where two first beams 301 are connected to the ends of a pair of second beams 302, and another first beam 301 is connected to the middle of the pair of second beams 302. Two symmetrical first spaces 3100 and second spaces 3200 can be formed between these three first beams 301 and the pair of second beams 302, and these first spaces 3100 and second spaces 3200 can each be used to house two battery case bodies 200, and their sizes can be correspondingly designed to fit the size of the case bodies 200.

[0073] Naturally, in other embodiments, the bracket body 300 may include a different number of first beams 301. For example, the bracket body 300 may include only one first beam 301 connected to the middle of the pair of second beams 302, in which case the space between the pair of second beams 302 may be divided into two symmetrical spaces for housing two battery 10 case bodies 200. Furthermore, for example, the bracket body 300 may include two first beams 301, each connected to both ends of the pair of second beams 302, to connect with each other and form a frame structure, the space within which the frame structure is used to housing one battery 10 case body 200. Furthermore, for example, the bracket body 300 may include four or more first beams 301, and the space between the pair of second beams 302 may be divided into three or more subspaces for correspondingly housing three or more battery 10 case bodies 200. The embodiments of this application do not limit the specific number of first beams 301 in the bracket body 300.

[0074] To allow for convenient attachment of the bracket body 300 to the vehicle 1, the extending directions of the first beam 301 and the second beam 302 may be made parallel to the length and width directions of the vehicle 1, respectively, thereby saving mounting space for the bracket body 300 on the vehicle 1.

[0075] Based on the embodiment of the present invention shown in Figure 2 above, Figure 4 shows a schematic configuration diagram of the case 20 of the battery 10 provided in the embodiment of the present invention.

[0076] As shown in Figure 4, the case 20 of the battery 10 includes a case body 200 for housing battery cells 100 (not shown in Figure 4), and a first stopper 210 installed on one side of the first wall 201 of the case body 200 away from the battery cells 100, wherein the first wall 201 is perpendicular to a first direction x, and after the case 20 is attached to the power consumption device, the first direction x becomes parallel to the direction of travel of the power consumption device, and the first stopper 210 is for limiting the relative displacement of the case 20 along the first direction x.

[0077] For example, the power consumption device in the embodiment of the present application may be the vehicle 1 described above, and after the battery 10 is attached to the vehicle 1, the first direction x may be parallel to the direction of travel of the vehicle 1. In some embodiments, the direction of travel of the vehicle 1 may be parallel to its longitudinal direction, that is, after the battery 10 is attached to the vehicle 1, the first direction x may be parallel to the longitudinal direction of the vehicle 1.

[0078] Naturally, the power consumption device in the embodiment of the present application may be of a different type than vehicle 1, and it may have a motion state, and the direction of that motion state may all be referred to as the direction of travel in the embodiment of the present application.

[0079] Referring to Figures 2 and 4, the case body 200 in the embodiment of the present application may include the first part 2100 and the second part 2200, and the first wall 201 of the case body 200 may be a wall formed after the first part 2100 and the second part 2200 engage with each other. Therefore, in the embodiment of the present application, the first stopper 210 installed on the first wall 201 may be installed independently on the first part 2100 of the case body 200, or independently on the second part 2200 of the case body 200, or as two parts, installed on the first part 2100 and the second part 2200 of the case body 200, respectively. For example, in the embodiment shown in Figure 4, the first stopper 210 is installed on one part of the case body 200.

[0080] In the embodiment of the present invention, the first stopper 210 is installed on one side of the first wall 201 of the case body 200 that is away from the battery cell 100. As can be understood, the battery cell 100 is housed in a cavity inside the case body 200, and the side of the case body 200 closer to the battery cell 100 can be understood as the inside of the case body 200, while the side of the case body 200 that is away from the battery cell 100 can be understood as the outside of the case body 200. Therefore, the side of the first wall 201 of the case body 200 that is away from the battery cell 100 can be understood as the outside of the first wall 201, and after the case 20 is attached to the power consumption device, the first stopper 210 installed on the outside of the first wall 201 can easily interact with the power consumption device to limit the relative displacement of the case 20 in the power consumption device.

[0081] Furthermore, if the first wall 201 on which the first stopper 210 is installed is perpendicular to the first direction x, and after the case 20 is attached to the power consumption device, the first stopper 210 can generate a force acting along the first direction x relative to the power consumption device, thereby limiting the relative displacement of the case 20 along the first direction x in the power consumption device.

[0082] For a power-consuming device that can move, its primary state of motion may be driving, and within that state, its mode of motion can vary in many ways. For example, a vehicle may have different states of motion such as starting, accelerating, decelerating, and braking while driving. In a driving state where the mode of motion of a power-consuming device changes in many ways, the elements inside the power-consuming device, such as a battery, are also greatly affected.

[0083] According to the technical solution of the embodiment of the present application, a first stopper 210 is installed on one side of the first wall 201 of the case body 200 of the battery case 20 away from the battery cell 100, and the first wall 201 is perpendicular to a first direction x. After the case 20 is attached to the power consumption device, the first direction x is parallel to the direction of travel of the power consumption device. Therefore, after the case 20 is attached to the power consumption device, the first stopper 210 can generate an acting force on the power consumption device along the first direction x. That is, the first stopper 210 can generate an acting force on the power consumption device along the direction of travel and the opposite direction of travel of the power consumption device. This limits the relative displacement of the case 20 along the direction of travel and the opposite direction of travel of the power consumption device, improves the mounting stability of the case 20 along the direction of travel and the opposite direction of travel of the power consumption device, reduces the influence of the power consumption device in a travel state on the battery 10 and its case 20, and ensures the normal operation of the battery 10 and the power consumption device in which it is located.

[0084] As needs to be explained, the first wall 201 in the embodiment of the present application may include a main structure and an auxiliary structure, the main structure can be approximately understood as a wall-like structure, and an auxiliary structure such as a protrusion or recess may be installed on a part of the surface of the wall-like structure so as to allow for the convenient installation of components related to the case 20 on the first wall 201. The first stopper 210 in the embodiment of the present application may be installed directly on the main wall-like structure of the first wall 201, or on an auxiliary structure such as a protrusion or recess in the main wall-like structure. For example, in the embodiment shown in Figure 4, the first stopper 210 is installed on an auxiliary protrusion in the main wall-like structure of the first wall 201 that protrudes outward from the first wall 201 along the first direction x. For convenience of explanation, the main structure and the auxiliary structure in the first wall 201 will not be distinguished below and will be collectively referred to as the first wall 201.

[0085] Regarding the first stopper 210 described above, Figure 5 shows a schematic perspective view, which may be a localized enlargement of portion A in Figure 4. Figure 6 shows a schematic exploded view of the first stopper 210. Figure 7 shows a schematic cross-sectional view of the first stopper 210 along the xz plane in Figure 5. In this plane, the xz plane is defined by the x and z directions, where the x direction is the first direction in the embodiment of the present application described above, and the z direction is parallel to the first wall 201 and perpendicular to the x direction. After the case 20 is attached to the power consumption device, the z direction may become parallel to the gravity direction, where the z direction includes the anti-gravity direction z1 and the gravity direction z2. For ease of display and understanding, Figure 5 and some of the accompanying drawings below also show a y direction perpendicular to the x and z directions, and these three directions together form a spatial rectangular coordinate system.

[0086] As shown in Figures 5 to 7, the first stopper 210 may include a first stop block 211 installed on the first wall 201 and capable of moving along a first direction x, and a buffer block 212 installed between the first stop block 211 and the first wall 201 and used to provide a buffer distance along the first direction x of the first stop block 211.

[0087] Specifically, after the case 20 is attached to the power consumption device, the first stop block 211 in the first stopper 210 interacts with the power consumption device to prevent relative displacement of the case. To ensure the wear resistance of the first stop block 211 and improve its service life, the first stop block 211 can be made of a wear-resistant material, which includes, but is not limited to, polyoxymethylene (POM) material having high mechanical strength and rigidity.

[0088] To conveniently attach the case 20 to a power consumption device, the first stopper 210 in the embodiment of the present application further includes a buffer block 212 installed between the first stop block 211 and the first wall 201, which can provide a buffer distance along the first direction x of the first stop block 211. In other words, the first stop block 211 in the embodiment of the present application does not need to be fixed to the first wall 201, but rather a buffer distance in the first direction x can be provided by installing the buffer block 212.

[0089] In the embodiments of the present invention, the buffering distance provided by the buffer block 212 can be optionally determined according to the thickness size of the buffer block 212 in a first direction x. For example, in the initial state, the buffer block 212 has a thickness d1 in the first direction, and in the maximum compression state of the buffer block, its thickness d2 in the first direction, and therefore the buffering distance provided by the buffer block 212 may be less than or equal to the difference between d1 and d2.

[0090] The buffer block 212 can be optionally made of an elastic material, which includes, but is not limited to, polyurethane (PU) material. A foam or plastic sponge can be made from the polyurethane material to form the buffer block 212 in the embodiment of the present application.

[0091] According to the technical solution of the embodiment of the present application, when attaching the case 20 to the power consumption device, the mutually coordinated installation of the buffer block 212 and the first stop block 211 allows the first stop block 211 to move into the case 20 along the first direction x, and the first stop block 211 does not provide excessive mounting resistance, allowing the case 20 to be conveniently attached to the power consumption device. Furthermore, after the case 20 is attached to the power consumption device, the first stop block 211 compresses the buffer block 212, thereby providing an elastic force to the first stop block 211, which is pressed tightly against the power consumption device in the first direction x, ensuring the mounting stability of the case 20 along the first direction x, that is, ensuring the mounting stability of the case 20 along the direction of travel and the direction of non-travel of the power consumption device.

[0092] Referencing Figures 5 to 7, the first stopper 210 of the embodiment of the present application may further include a first fixing member 213, the first stop block 211 being installable on the first wall 201 by the first fixing member 213, and the first fixing member 213 providing a buffer space between the first stop block 211 and the buffer block 212 along a first direction x.

[0093] Specifically, in the embodiment of the present invention, the first fixing member 213 does not directly fix the first stop block 211 to the first wall 201, but rather installs the first stop block 211 on the first wall 201 in a limited position, and provides a buffer space between the first stop block 211 and the buffer block 212 along the first direction x. When the case 20 is attached to the power consumption device, the first stop block 211 can be subjected to relative displacement in the first direction x by the buffer block 212.

[0094] For example, the first fixing member 213 in the embodiment of the present application includes, but is not limited to, a screw, one end of which is fixed to the first wall 201, and in the first direction x, there is a certain buffer space between the screw head and the first wall 201, and the first stop block 211 and buffer block 212 are installed in the buffer space between the screw head and the first wall 201. When the case 20 is attached to the power consumption device, in the first direction x, the first stop block 211 generates a relative displacement between the screw head and the first wall 201 by the buffer block 212.

[0095] In the embodiment shown in Figure 6, the first fixing member 213 may be a stepped screw, which has a stepped structure, with the first step fixed to the first wall 201, and the second step and screw head working in conjunction with the first stop block 211 and buffer block 212 to provide a buffer space between the first stop block 211 and buffer block 212.

[0096] Specifically, when case 20 is not attached to the power consumption device, the buffer block 212 is in a first state due to the action of the first fixing member 213 and the first stop block 211. This first state may be an uncompressed initial state or a slightly compressed state. In this first state, the buffer block 212 has a thickness d3 in the first direction, and in the maximum compression state, the buffer block 212 has a thickness d2 in the first direction. Thus, in the embodiment of the present application, the buffer distance provided by the buffer block 212 to the first stop block 211 may be the difference between d3 and d2. The first fixing member 213 is for determining the first state of the buffer block 212 and for limiting the buffer distance along the first direction x of the first stop block 211 based on the first state of the buffer block 212.

[0097] According to the technical solution of the embodiment of the present application, the first stop block 211 is installed on the first wall 201 of the case body 200 by the first fixing member 213, and a buffer space is provided between the first stop block 211 and the buffer block 212, so that the first stop block 211 can be subjected to relative displacement in the first direction x by the buffer block 212. Therefore, the first stop block 211 does not provide excessive mounting resistance, and the case 20 can be easily attached to the power consumption device. Furthermore, after the case 20 is attached to the power consumption device, the mutual cooperation between the first stop block 211 and the buffer block 212 ensures mounting stability along the first direction of the case 20, that is, it ensures mounting stability along the travel direction and the non-travel direction of the power consumption device.

[0098] As can be selected, as shown in Figures 5 and 6, in the embodiments of the present application, the overall shape of the first stop block 211 may be approximately a solid block, and the mounting position may be located in the middle of it, and the first fixing member 213 installs the first stop block 211 on the first wall 201 in a position-limited manner by the mounting position in the middle of the first stop block 211, and according to this embodiment, a preferred position-fixing limiting effect can be achieved compared to installing the first fixing member 213 at other positions on the first stop block 211. Of course, depending on the specific application scene or demand, the first fixing member 213 may be installed at other positions on the first stop block 211, for the purpose of providing a buffer space between the first stop block 211 and the buffer block 212, so that the buffer block 212 can cause a relative displacement in the first direction x on the first stop block 211, and the embodiments of the present application do not limit the specific position of the first fixing member 213.

[0099] In addition, as can be selected, in the embodiment of the present invention, the overall shape of the buffer block 212 may be approximately a solid structure in order to increase the contact area between the buffer block 212 and other members and its mounting stability. Furthermore, a through hole is provided correspondingly in the middle of the buffer block 212, and the first fixing member 213 installs the buffer block 212 to the first wall 201 through the through hole.

[0100] Optionally, in some application scenarios, the case 20 may be mounted on the power consumption device facing the anti-gravity direction z1, for example, if the power consumption device is vehicle 1, the case 20 can be lifted and mounted on the chassis of vehicle 1, i.e., the case 20 is mounted on vehicle 1 facing the anti-gravity direction z1.

[0101] In this application scenario, as shown in Figures 5 to 7, a wedge angle may be provided at the first end 2111 of the first stop block 211 in the embodiment of the present invention, and the first end 2111 of the first stop block 211 is the end facing the anti-gravity direction z1. Therefore, when attaching the case 20 to the power consumption device facing the anti-gravity direction z1, the first end 2111 with the wedge angle of the first stop block 211 can be used to gradually move it toward the anti-gravity direction z1, and the first end 2111 can guide and position the case 20 relative to the power consumption device when attaching the case 20, making it easier to attach the case 20 to the power consumption device.

[0102] Refer to Figures 6 and 7 for further options, in the embodiment of the present invention, a housing area 2011 capable of accommodating the first stopper 210 is provided in the first wall 201.

[0103] Specifically, the accommodation area 2011 may be appropriate for the first stopper 210. For example, the accommodation area 2011 may include a quadrilateral groove to appropriately accommodate the first stop block 211 in the first stopper 210. Furthermore, for example, in the first direction x, the depth of the quadrilateral groove needs to be greater than the thickness of the buffer block 212, thereby providing space in the quadrilateral groove for accommodating the buffer block 212. Furthermore, for example, if the first fixing member 213 is a screw, the accommodation area 2011 may further include a screw hole to appropriately attach the screw.

[0104] According to the technical solution of the embodiment of the present application, by providing a housing area 2011 in the first wall 201 of the case 20 to house the first stopper 210, the mounting space for the first stopper 210 can be saved, and at the same time, the housing area 2011 can protect the first stopper 210 so as to prevent it from being damaged by external influences and thus improve the service life of the first stopper 210 in the case 20.

[0105] Figure 8 shows a schematic plan view of the case 20 of the battery 10 provided in the embodiment of the present invention, along the xy plane.

[0106] Optionally, as shown in Figure 8, the case 20 may include a plurality of the first stoppers 210 that can be distributed and installed on two parallel first walls 201 in the case body 200.

[0107] Specifically, after the case 20 is attached to the power consumption device, both of these first walls 201 are perpendicular to the first direction x, that is, perpendicular to the direction of travel of the power consumption device. In the embodiment of the present application, by providing a plurality of first stoppers 210 in the space between the two first walls 201 and distributing them on these two first walls 201, the first stoppers 210 on the two first walls 201 of the case 20 can each generate an acting force along the first direction x relative to the power consumption device. In this way, the case 20 is tightly sandwiched between the power consumption device in the first direction x, and the relative displacement of the case 20 along the first direction x relative to the power consumption device is further limited, thereby improving the mounting stability of the case 20 to the power consumption device.

[0108] As needs to be explained, in this application, the two mutually parallel first walls 201 can be understood as two main wall-like structures that are parallel to each other. Furthermore, this mutual parallelism does not mean absolute parallelism, but may be approximately parallel.

[0109] The number of first stoppers 210 installed on the two first walls 201 may or may not be equal. Multiple first stoppers 210 can be arranged along the first wall 201 in the y-direction, as selectable.

[0110] As an example, two first stoppers 210 can be installed on one first wall 201, and these two first stoppers 210 can be distributed in the areas at both ends of the first wall 201 along the y-direction, that is, distributed in the two corner areas of the case body 200. Alternatively, only one first stopper 210 may be installed on another first wall 201, and this one first stopper 210 can be installed in the central area of ​​the other first wall 201 along the y-direction.

[0111] As another example, as shown in Figure 8, one first stopper 210 is installed at each end of the two first walls 201 in the y-direction, that is, four first stoppers 210 are distributed and installed in the four corner areas of the case body 200.

[0112] According to the technical solution of the embodiment of the present invention, the multiple first stoppers 210 included in the case 20 are distributed and installed in the four corner regions of the case body 200, thereby limiting the relative displacement of the case 20 in the four corner regions with respect to the power consumption device and comprehensively improving the mounting stability of the case 20 to the power consumption device.

[0113] Figure 9 shows another schematic configuration diagram of the case 20 of the battery 10 provided in the embodiment of the present application.

[0114] Optionally, as shown in Figure 9, the case 20 of the battery 10 provided in the embodiment of the present application may include a second stopper 220 installed on one side of the case body 200 away from the battery cells and used to limit the relative displacement of the case 20 along a second direction z, after the case 20 is attached to a power consumption device and the second direction z is parallel to the direction of gravity.

[0115] To make it understandable, the battery cell 100 is housed in a cavity inside the case body 200, and one side of the case body 200 closer to the battery cell 100 is considered the inside of the case body 200, while the other side of the case body 200 further away from the battery cell 100 is considered the outside of the case body 200. Therefore, in the embodiment of the present application, the second stopper 220 is installed on the outside of the case body 200, and after the case 20 is attached to the power consumption device, the second stopper 220 can limit the displacement of the case 20 along the second direction z, that is, the relative displacement of the case 20 along the gravity direction z2 and the anti-gravity direction z1.

[0116] According to the technical solution of the embodiment of the present application, a second stopper 220 is installed on one side of the case body 200 of the battery case 20 away from the battery cell 100, and after the case 20 is attached to the power consumption device, the second stopper 220 can generate an acting force along the second direction z with respect to the power consumption device, that is, the second stopper 220 can generate an acting force along the direction of gravity z2 and the direction of anti-gravity z1 with respect to the power consumption device, thereby limiting the relative displacement of the case 20 along the direction of gravity z2 and the direction of anti-gravity z1, further improving the mounting stability of the case 20 to the power consumption device, and ensuring the normal operation of the battery 10 and the power consumption device in which it is located.

[0117] The second stopper 220 provided in the embodiment of the present application can be optionally installed on the outside of any wall of the case body 200, for the purpose that after the case 20 is attached to the power consumption device, the second stopper 220 can come into contact with the power consumption device and generate forces acting on the power consumption device along the direction of gravity z2 and the direction of antigravity z1, and the embodiment of the present application does not limit the specific position of the second stopper 220 on the outside of the case body 200.

[0118] For example, in the embodiment shown in Figure 9, the second stopper 220 can be installed on the first wall 201 of the case body 200 in the embodiment of the present application described above. In this case, Figure 10 shows a schematic perspective view of the second stopper 220, and Figure 10 may be a local enlargement view of portion B in Figure 9. Figure 11 is a schematic cross-sectional view of the second stopper 220 along the xz plane in Figure 10.

[0119] For example, in the embodiment shown in Figures 10 and 11, the first wall 201 may extend along a first direction x away from the battery cell 100 inside the case body 200 and may include an extended portion 2012 used to install the second stopper 220.

[0120] Specifically, the first wall 201 includes an extension 2012 that extends outward from the case body 200 along a first direction x, and after the second stopper 220 is attached to the extension 2012 in this manner, it can be installed facing the power consumption device in a second direction z, and can generate interaction with the power consumption device in the second direction z.

[0121] Referring back to Figure 9, it can be seen that the case body 200 may include not only the first wall 201, but also a second wall 202 perpendicular to the third direction y (i.e., the y direction shown in the figure). If the second stopper 220 is installed on the second wall 202, the second wall 202 may similarly include an extended portion for installing the second stopper 220, and this extended portion of the second wall 202 may extend outward from the case body 200 along the y direction.

[0122] In addition to including the first wall 201 and the second wall 202, the case body 200 may also include a third wall 203 perpendicular to the second direction z. In this case, the second stopper 220 can be installed directly outside the third wall 203, and the purpose of this is for them to interact with the power consumption device.

[0123] In some embodiments, the second stopper 220 can be optionally replaced with an elastic stop block, which, after the case 20 is mounted to the power consumer, is compressed and comes into contact with the power consumer, creating an elastic force between the compressed elastic stop block and the power consumer, and the elastic stop block is pressed tightly against the power consumer in the second direction z, ensuring mounting stability of the case 20 along the second direction z, i.e., ensuring mounting stability of the case 20 along the gravity direction z2 and anti-gravity direction z1 of the power consumer.

[0124] The material of the elastic stop block in the embodiments of the present application may include, but is not limited to, a rubber material that is not only elastic but also has a certain degree of wear resistance and strength. After the elastic stop block of the rubber material is attached to the power consumption device, it has little impact on the power consumption device, ensures mounting stability between the case 20 and the power consumption device, avoids wear of the power consumption device due to vibration of the case 20, and reduces the risk of rust occurring on the power consumption device.

[0125] Optionally, in order to secure the attachment of case 20 to the power consumption device, the compression amount of the elastic stop block can be set to a predetermined threshold or higher, so as to ensure that the force acting between the elastic stop block and the power consumption device reaches a predetermined threshold or higher after case 20 has been attached to the power consumption device. For example, the threshold for the compression amount of the elastic stop block can be set to 3 mm or higher.

[0126] In the embodiments shown in Figures 10 and 11, based on the fact that the second stopper 220 is an elastic stop block, a chamfered structure is installed on the first end 2201 of the elastic stop block, which is one end of the elastic stop block facing the anti-gravity direction z1.

[0127] When case 20 is attached to the power consumption device along the anti-gravity direction z1, the first end 2201 of the elastic stop block facing the anti-gravity direction comes into contact with the power consumption device first and acts upon it. According to the technical solution of the embodiment of the present application, by installing a chamfered structure on the first end 2201 of the elastic stop block, the first end 2201 of the elastic stop block is easily compressed by the power consumption device. Furthermore, compared to a sharp-angled structure, the chamfered structure avoids stress concentration, extending the service life of the elastic stop block. In addition, the chamfered structure can also improve the aesthetic appearance of the elastic stop block.

[0128] As an example, Figures 10 and 11 show a method of attaching the second stopper 220 to the extended portion 2012.

[0129] The extension portion 2012 includes a housing area to accommodate the second stopper 220, which can be selected, and the second stopper 220 can be attached and installed in the extension portion 2012 in this way. Furthermore, if the second stopper 220 is an elastic stop block, it has a projection facing the extension portion 2012, and the extension portion 2012 has an engagement groove for engaging the projection, which allows the elastic stop block to be stably attached and installed in the extension portion 2012 in this way.

[0130] Naturally, aside from the mounting methods shown in the embodiments in Figures 10 and 11, the second stopper 220 can be installed and mounted on the extension portion 2012 by any other method, such as by attaching it to the extension portion 2012 with a fixing member, and the embodiments of this application do not specifically limit this.

[0131] Selectively, the centers of the first stopper 210 and the second stopper 220 lie on a first plane parallel to the plane defined by the first direction x and the second direction z, i.e., the xz plane.

[0132] In some embodiments, the center of the first stopper 210 can be understood as the geometric center or centroid of any module within the first stopper 210, for example, the center of the first stopper 210 may be the geometric center or centroid of the first stop block 211. Similarly, the center of the second stopper 220 can also be understood as the geometric center or centroid of any module within the second stopper 220, for example, the center of the second stopper 220 may be the geometric center or centroid of the elastic stop block.

[0133] In this case, Figure 12 is a schematic perspective view of the first stopper 210 and the second stopper 220 in the embodiment of the present application.

[0134] In the embodiment shown in Figure 12, both the first stopper 210 and the second stopper 220 can be installed on the first wall 201 of the case body 200, and the first stopper 210 and the second stopper 220 are installed adjacent to each other. Specifically, the first stopper 210 can be installed in a first region of the first wall 201, and the second stopper 220 can be installed in an extended portion 2012 in which the first region extends outward from the case 20 along a first direction x. In addition, in this embodiment, the centers of the first stopper 210 and the centers of the second stopper 220 are on a first plane parallel to the xz plane.

[0135] In addition to the first stopper 210 and the second stopper 220 being able to be installed on the same first wall 201 of the case body 200, as in the embodiment shown in Figure 12, the first stopper 210 may be installed on one first wall 201 of the case body 200, and the second stopper 220 may be installed symmetrically on another first wall 201 of the case body 200, and the centers of the first stopper 210 and the second stopper 220 may be on a first plane parallel to the xz plane.

[0136] According to the technical solution of the embodiment of the present application, the centers of the first stopper 210 and the second stopper 220 are both on a first plane parallel to the xz plane. After the case 20 is attached to the power consumption device, the forces acting on the first stopper 210 and the power consumption device, and the forces acting on the second stopper 220 and the power consumption device converge on the same plane, further improving the mounting stability of the case 20 to the power consumption device. Furthermore, if the first stopper 210 and the second stopper 220 are installed adjacent to each other on the same first wall 201, the forces acting between the first stopper 210 and the second stopper 220 and the power consumption device become even more concentrated, further improving the mounting stability of the case 20 to the power consumption device. Also, because the first stopper 210 and the second stopper 220 are installed adjacent to each other, installation and repair of the first stopper 210 and the second stopper 220 become more convenient.

[0137] Furthermore, referring to Figure 12, the case 20 may also include a first mounting member 230 installed on one side of the first wall 201 of the case body 200 away from the battery cells, i.e., installed on the outside of the first wall 201 of the case body 200, wherein the first mounting member 230 is for locking the case 20 to the power consumption device, and the first stopper 210 may be installed adjacent to the first mounting member 230.

[0138] For example, in the embodiment shown in Figure 12, the first mounting member 230 may be a locking part, and the power consumption device may have a locking mechanism and a passage. The locking part moves along the passage, and the locking mechanism is arranged so that when the locking part moves to a predetermined position in the passage, it locks the locking part, thereby locking the case 20 to the power consumption device. The locking mechanism may also be arranged to release the locking from the locking part, detach the locking part from the passage, and unlock the case 20 from the power consumption device.

[0139] After the case 20 is attached to the power consumption device by the first mounting member 230, the first stopper 210 can generate an acting force on the power consumption device along the direction of travel and the direction of non-travel of the power consumption device, thereby limiting the relative displacement of the case 20, and especially the members surrounding the first stopper 210 in the case 20, along the direction of travel and the direction of non-travel of the power consumption device. Consequently, the stability of the members surrounding the first stopper 210 in the case 20 is high, and according to the technical solution of the embodiment of the present application, by installing the first mounting member 230 for locking the case 20 adjacent to the first stopper 210, the stability of the first mounting member 230 can be improved, and the mounting stability of the case 20 to the power consumption device can be further improved.

[0140] Furthermore, as shown in Figure 12, if the second stopper 220 is installed adjacent to the first stopper 210, the second stopper 220 will also be installed adjacent to the first mounting member 230, and it can be understood that the mounting stability of the first mounting member 230 and the case 20 can be further improved.

[0141] In this embodiment, Figure 13 shows a schematic perspective view of the case 20 of the battery 10. Figure 14 shows a schematic plan view of the case 20 in Figure 13 along the xy plane.

[0142] As shown in Figures 13 and 14, the case 20 may include a plurality of first stoppers 210 and a plurality of second stoppers 220, in which the plurality of first stoppers 210 can be distributed and installed on two parallel first walls 201 of the case body 200, and the plurality of second stoppers 220 can be installed adjacent to the plurality of first stoppers 210 in a one-to-one correspondence.

[0143] Optionally, the case 20 further includes a plurality of the first mounting members 230 which can be distributed and installed in the four corner areas of the case body 200 to ensure the stability of the lock mounting of the case 20.

[0144] For example, in the embodiment shown in Figure 14, these multiple first mounting members 230 are distributed in the four corner regions of the case body 200 and installed on two parallel first walls 201. Furthermore, these multiple first mounting members 230 may be installed adjacent to the first stopper 210 and the second stopper 220 in a corresponding manner so as to ensure the mounting stability of the first mounting members 230 and the case 20 by the first stopper 210 and the second stopper 220.

[0145] The relevant technical solutions for the battery case 20 provided in the embodiment of the present application have been described above with reference to Figures 4 to 14. Now, the relevant technical solutions for the bracket 30 for mounting the battery case 20 provided in the embodiment of the present application will be described below with reference to Figures 15 to 24.

[0146] Based on the embodiment of the present application shown in Figure 3, Figure 15 shows a schematic configuration diagram of the bracket 30 provided in the embodiment of the present application. The bracket 30 is applicable to a power consumption device, which may be the power consumption device described in the embodiments shown in Figures 4 to 14 above, and includes, but is not limited to, the vehicle 1 shown in Figure 1 above.

[0147] As shown in Figure 15, the bracket 30 includes a bracket body 300 for mounting a battery case 20 (not shown) of a power consumption device for housing battery cells 100, and a third stopper 310 installed on one side of the first beam 301 of the bracket body 300 closer to the case 20, wherein the extending direction of the first beam 301 is perpendicular to a first direction x parallel to the travel direction of the power consumption device, and the third stopper 310 is for limiting the relative displacement of the case 20 along the first direction x.

[0148] Specifically, for technical solutions related to the bracket body 300 and the first beam 301 in the embodiment of the present application, refer to the relevant description of the embodiment shown in Figure 3 above. The attachment of the battery case 20 to the power consumption device in Figures 4 to 14 above can be understood as attaching the battery case 20 to the bracket 30 in the embodiment of the present application described below, and specifically, the bracket 30 can be attached to the bracket body 300.

[0149] In the embodiment of the present application, the extending direction of the first beam 301 in the bracket body 300 is perpendicular to the first direction x, and the first direction x is parallel to the travel direction of the power consumption device. If the travel direction of the power consumption device is the longitudinal direction of the power consumption device, then in the embodiment of the present application, the extending direction of the first beam 301 is perpendicular to the longitudinal direction of the power consumption device, that is, parallel to the width direction of the power consumption device.

[0150] Furthermore, in the embodiment of the present invention, a third stopper 310 is installed on one side of the first beam 301 closer to the case 20 to limit the relative displacement of the case 20 along the first direction x.

[0151] For ease of understanding, in the embodiment of the present application, the side of the first beam 301 closest to the case 20 may be referred to as the inside of the first beam 301, and this inside of the first beam 301 can form a space for housing the case 20.

[0152] Specifically, after the battery case 20 is attached to and housed in the bracket body 300, the third stopper 310 installed inside the first beam 301 interacts with the case 20 to limit the relative displacement of the case 20 and the battery 10 power consumption device inside it.

[0153] Furthermore, if the extension direction of the first beam 301 on which the third stopper 310 is installed is perpendicular to the first direction x, and after the case 20 is attached to and housed in the bracket body 300, the third stopper 310 generates a force acting on the case 20 along the first direction x, thereby limiting the relative displacement of the case 20 along the first direction x in the bracket body 300.

[0154] According to the technical solution of the embodiment of the present application, a third stopper 310 is installed on one side of the first beam 301 of the bracket body 300 of the bracket 30 that is close to the case 20 of the battery 10, and the extending direction of the first beam 301 is perpendicular to a first direction x which is parallel to the travel direction of the power consumption device. Therefore, after the case 20 of the battery 10 is attached to the bracket body 300 of the power consumption device, the third stopper 310 can generate an acting force on the case 20 along the first direction x, that is, the third stopper 310 can generate an acting force on the case 20 along the travel direction and the opposite travel direction of the power consumption device. This limits the relative displacement of the case 20 along the travel direction and the opposite travel direction of the power consumption device, improves the mounting stability of the case 20 along the travel direction and the opposite travel direction of the power consumption device, reduces the influence of the power consumption device in motion on the battery 10 and its case 20, and ensures the normal operation of the battery 10 and the power consumption device in which it is located.

[0155] In the embodiments of the present application, after the battery case 20 is attached to the bracket 30 of the power consumption device, a third stopper 310 installed on the bracket body 300 can cooperate with the first stopper 210 installed on the case body 200 in the embodiments of the present application described above, and the third stopper 310 can generate an acting force on the first stopper 210 along the direction of travel and the direction of non-travel of the power consumption device, thereby limiting the relative displacement of the case 20 along the direction of travel and the direction of non-travel of the power consumption device.

[0156] Regarding the third stopper 310 described above, Figure 16 shows a schematic perspective view, and Figure 16 may be a local enlargement view of portion C in Figure 15. Figure 17 shows a schematic exploded view of the third stopper 310. Figure 18 shows a schematic cross-sectional view of the third stopper 310 along the xz plane in Figure 16, where the xz plane is a plane defined by the x and z directions, where the x direction is the first direction x in the embodiment of the present application described above, and the z direction may be parallel to the gravity direction, where the z direction includes the anti-gravity direction z1 and the gravity direction z2.

[0157] As shown in Figures 16 to 18, the third stopper 310 may include a third stop block 311 with a wedge angle installed at one end 3111 facing the direction of gravity, and a second fixing member 312 for fixing the third stop block 311 to the first beam 301.

[0158] As can be selected, as shown in Figures 16 and 17, in the embodiments of the present application, the overall shape of the third stop block 311 may be approximately a solid block, and a mounting position may be located in its middle, and the second fixing member 312 fixes the third stop block 311 to the first beam 301 by the mounting position in the middle of the third stop block 311, and according to this embodiment, a preferable fixing effect can be achieved compared to installing the second fixing member 312 at other positions on the third stop block 311. In this embodiment, the second fixing member 312 includes, but is not limited to, screws and nuts that allow the third stop block 311 to be conveniently attached and detached.

[0159] Specifically, after the case 20 is attached to the bracket 30, the third stop block 311 in the third stopper 310 acts relative to the case 20 to prevent relative displacement of the case 20. To ensure the wear resistance of the third stop block 311 and improve its service life, the third stop block 311 can be made of a wear-resistant material, which includes, but is not limited to, polyoxymethylene (POM) material having high mechanical strength and rigidity.

[0160] In some application scenarios, the case 20 may be mounted to the power consumption device facing the anti-gravity direction z1, for example, if the power consumption device is vehicle 1, the case 20 can be lifted and mounted to a bracket 30 on the chassis of vehicle 1, i.e., the case 20 is mounted to the bracket 30 on vehicle 1 facing the anti-gravity direction.

[0161] In this application scenario, a wedge angle may be provided at one end 3111 of the third stop block 311 facing the anti-gravity direction in the embodiment of the present invention. This allows the case 20 to be gradually moved toward the anti-gravity direction z1 with the help of one end 3111 of the third stop block 311 when attaching it to the bracket 30. This end 3111 can guide and position the case 20 relative to the bracket 30 when attaching it, making it easier to attach the case 20 to the bracket 30.

[0162] In the embodiments of the present application, it is necessary to explain that the bracket 30 includes a third stopper 310 which can engage with the first stopper 210 of the case 20 in the embodiments of the present application described above. In other embodiments, the bracket 30 may include the first stopper 210, and the case 20 may include the third stopper 310, that is, even if the stoppers in the bracket 30 and the case 20 are interchangeable, the first stopper 210 and the third stopper 310 can engage with each other after the case 20 is attached to the bracket 30, thereby achieving stable mounting of the case 20 to the bracket 30.

[0163] However, the first stopper 210 has a somewhat complex structure and requires a buffer block 212 to achieve the cushioning motion of the first stop block 211. Therefore, it requires more frequent repair or replacement than the third stopper 310. Installing the first stopper 210 in the case 20 makes it easier to repair and replace the first stopper 210.

[0164] Figure 19 shows a schematic plan view of the bracket 30 provided in the embodiment of the present application.

[0165] As optional, as shown in Figure 19, the bracket 30 may include a plurality of the third stoppers 310 that can be distributed and installed on at least two parallel first beams 301 in the bracket body 300.

[0166] Specifically, in the embodiment of the present application, the extending directions of at least two first beams 301 are both perpendicular to the first direction x, that is, perpendicular to the direction of travel of the power consumption device. In the embodiment of the present application, the space between at least two first beams 301 provides a plurality of third stoppers 310 which are distributed and installed on these at least two first beams 301. This allows the third stoppers 310 on at least two first beams 301 to generate an acting force on the case 20 along the first direction x in the bracket body 300. In this way, the case 20 is tightly sandwiched between the bracket body 300 in the first direction x, and the relative displacement of the case 20 along the first direction x in the bracket 30 is further limited, thereby improving the mounting stability of the case 20 to the power consumption device.

[0167] In the embodiments of the present invention, optionally, a plurality of third stoppers 310 may be further distributed and installed in the four corner regions of the space for housing the case 20 in the bracket body 300, and further installed corresponding to the four corner regions of the case 20, thereby limiting the relative displacement of the four corner regions of the case 20 at the bracket 30 and comprehensively improving the mounting stability of the case 20 to the bracket 30 and the power consumption device on which it is located.

[0168] For example, in the embodiment shown in Figure 19, the bracket body 300 includes a first space 3100 and a second space 3200 for housing the case 20, and a plurality of third stoppers 310 are distributed and installed in the four corner areas of the first space 3100 and the second space 3200 respectively to improve the mounting stability of the two cases 20 attached to the bracket 30.

[0169] Figure 20 shows a schematic configuration diagram of the bracket 30 provided in the embodiment of the present application.

[0170] Optionally, as shown in Figure 20, the bracket 30 provided in the embodiment of the present application may include a fourth stopper 320 mounted on the bracket body 300 and used to limit the relative displacement of the case 20 along a second direction z parallel to the direction of gravity.

[0171] In the embodiments of the present application, the fourth stopper 320 can be optionally installed on any beam of the bracket body 300, and in some embodiments, it may be installed on one side of the arbitrary beam in the bracket body 300 in the direction of gravity, or on one side of the arbitrary beam in the direction of anti-gravity.

[0172] According to the technical solution of the embodiment of the present application, by installing the fourth stopper 320 on the bracket body 300, the fourth stopper 320 can generate an acting force on the case 20 along the second direction z, that is, the fourth stopper 320 can generate an acting force on the case 20 along the direction of gravity z2 and the direction of anti-gravity z1. This limits the relative displacement of the case 20 along the direction of gravity z2 and the direction of anti-gravity z1, further improving the mounting stability of the case 20 to the bracket 30, and ensuring the normal operation of the battery 10 and the power consumption device in which it is located.

[0173] For example, in the embodiment shown in Figure 20, the fourth stopper 320 can similarly be installed on the first beam 301 of the bracket body 300 in the embodiment of the present application. In this case, Figure 21 shows a schematic perspective view of the fourth stopper 320, and Figure 21 may be a localized enlarged view of portion D in Figure 20.

[0174] For example, in the embodiment shown in Figure 21, the fourth stopper 320 is installed on one side of the first beam 301 in the direction of gravity z2 and includes a groove structure 321 with an opening facing the direction of gravity z2.

[0175] By adopting this embodiment, when attaching the battery case 20 to the bracket 30 in the anti-gravity direction z1, the groove structure 321 installed on one side of the first beam 301 in the gravity direction z2 can conveniently contact and engage with the case 20.

[0176] Specifically, the groove structure 321 accommodates the protruding member inside the case 20 of the battery 10, thereby enabling engagement between the groove structure 321 and the protruding member inside the case 20, limiting the relative displacement of the case 20 on the bracket body 300, and improving the mounting stability of the case 20 to the bracket 30.

[0177] In some embodiments, the groove structure 321 in the embodiments of the present application can cooperate with the second stopper 220 in the embodiments of the present application described above, and the groove structure 321 can accommodate the second stopper 220 and be pressed tightly against the second stopper 220 to achieve tight clamping of the case 20 to the bracket body 300 in the second direction z, thereby improving the mounting stability of the bracket body 300 of the case 20 along the gravity direction z2 and the anti-gravity direction z1.

[0178] Furthermore, the groove structure 321 not only enables tight clamping of the case 20 to the bracket body 300 in the second direction z, but also enables positional limitation of the case 20 to the bracket body 300 in the third direction y, thereby improving the mounting stability of the case 20 along the third direction y relative to the bracket body 300.

[0179] In the embodiments of the present application, since the fourth stopper 320 needs to interact with the case 20, the material of the fourth stopper 320 includes, but is not limited to, a wear-resistant and rust-resistant material such as stainless steel, in order to prevent rusting due to wear on the case 20 and to maintain a tight grip between the fourth stopper 320 and the case 20. Furthermore, the fourth stopper 320 can achieve good tight cooperation with the second stopper 220 in the case 20, for example, an elastic stop block.

[0180] In the embodiments of the present application, it is necessary to explain that the bracket 30 includes a fourth stopper 320 which can interact with the second stopper 220 of the case 20 in the embodiments of the present application described above. In other embodiments, the bracket 30 may include the second stopper 220, and the case 20 may include the fourth stopper 320, that is, even if the stoppers in the bracket 30 and the case 20 are interchangeable, the second stopper 220 and the fourth stopper 320 can interact with each other after the case 20 is attached to the bracket 30, thereby achieving stable mounting of the case 20 to the bracket 30.

[0181] However, if the second stopper 220 is an elastic stop block, it will require more frequent repair or replacement than the fourth stopper 320. Therefore, by installing the second stopper 220 in the case 20, the repair and replacement of the second stopper 220 can be made more convenient.

[0182] The centers of the third stopper 310 and the fourth stopper 320 may be located on a first plane parallel to the plane defined by the first direction x and the second direction z, respectively.

[0183] In some embodiments, the center of the third stopper 310 can be understood as the geometric center or centroid of any module within the third stopper 310, for example, the center of the third stopper 310 may be the geometric center of the third stop block 311. Similarly, the center of the fourth stopper 320 can also be understood as the geometric center or centroid of any module within the fourth stopper 320, for example, the center of the fourth stopper 320 may be the geometric center of the groove structure 321.

[0184] In this case, Figure 22 shows a schematic perspective view of the third stopper 310 and the fourth stopper 320 in the embodiment of the present application.

[0185] In the embodiment shown in Figure 22, both the third stopper 310 and the fourth stopper 320 are installed on the same first beam 301 of the bracket body 300, and the third stopper 310 and the fourth stopper 320 may be installed adjacent to each other. Specifically, the third stopper 310 and the fourth stopper 320 are installed on mutually perpendicular and adjacent sides of the first beam 301. In this embodiment, the centers of the third stopper 310 and the fourth stopper 320 are on a first plane parallel to the xz plane.

[0186] In addition to the third stopper 310 and the fourth stopper 320 being able to be installed on the same first beam 301 of the bracket body 300, as in the embodiment shown in Figure 22, the third stopper 310 may be installed on one first beam 301 of the bracket body 300, and the fourth stopper 320 may be installed on another first beam 301 of the bracket body 300, and the centers of the third stopper 310 and the fourth stopper 320 may similarly be on a first plane parallel to the xz plane.

[0187] According to the technical solution of the embodiment of the present application, the centers of the third stopper 310 and the fourth stopper 320 are both on a first plane parallel to the xz plane. After the case 20 is attached to the bracket 30, the forces acting on the third stopper 310 and the case 20, and the forces acting on the fourth stopper 320 and the case 20 converge on the same plane, further improving the mounting stability of the case 20 to the bracket 30. Furthermore, if the third stopper 310 and the fourth stopper 320 are installed adjacent to each other on the same first beam 301, the forces acting between the third stopper 310 and the fourth stopper 320 and the case 20 become even more concentrated, further improving the mounting stability of the case 20 to the bracket 30. Also, because the third stopper 310 and the fourth stopper 320 are installed adjacent to each other, installation and repair of the third stopper 310 and the fourth stopper 320 become more convenient.

[0188] Furthermore, referring to Figure 22, the bracket 30 may further include a second mounting member 330 for locking the case 20 onto the bracket body 300, and the third stopper 310 may be installed adjacent to the second mounting member 330.

[0189] For example, in the embodiment shown in Figure 22, the second mounting member 330 may include a locking mechanism and passage that cooperate with the first mounting member 230 (for example, the locking portion shown in Figure 12) in the case 20 to enable locking and unlocking of the case 20 to the bracket 30.

[0190] According to the technical solution of the embodiment of the present application, by installing the second mounting member 330 for locking the case 20 adjacent to the third stopper 310, the reliability of the locking of the case 20 by the second mounting member 330 can be improved by the position-limiting action of the third stopper 310, and further the mounting stability of the case 20 to the bracket 30 can be improved.

[0191] Furthermore, as shown in Figure 22, if the fourth stopper 320 is installed adjacent to the third stopper 310, the fourth stopper 320 will also be installed adjacent to the second mounting member 330, which can be seen as further improving the reliability of the locking of the case 20 by the second mounting member 330 and the stability of the case 20's mounting to the bracket 30.

[0192] In this embodiment, Figure 23 shows a schematic perspective view of the bracket 30. Figure 24 shows a schematic plan view of the case 20 in Figure 23 along the xy plane.

[0193] As shown in Figures 23 and 24, the bracket 30 may include a plurality of third stoppers 310 and a plurality of fourth stoppers 320, wherein the plurality of third stoppers 310 can be distributed and installed on at least one first beam 301 of the bracket body 300, and the plurality of fourth stoppers 320 are installed adjacent to the plurality of third stoppers 310 in a one-to-one correspondence.

[0194] Optionally, the bracket 30 may further include a plurality of the second mounting members 330, which are distributed and installed in the four corner regions of the space for housing the case 20 in the bracket body 300, and may also be installed corresponding to the four corner regions of the case 20. This limits the relative displacement of the case 20 at the bracket 30 in the four corner regions of the case 20, thereby comprehensively improving the mounting stability of the case 20 to the bracket 30 and the power consumption device in which it is located.

[0195] For example, in the embodiment shown in Figure 24, the bracket body 300 includes two spaces, space 3100 and space 3200, for housing the case 20. Multiple second mounting members 330 are distributed and installed in the four corner regions of spaces 3100 and 3200, respectively, and are installed on two parallel first beams 301. Furthermore, these multiple second mounting members 330 can be installed adjacent to and corresponding to the third stopper 310 and the fourth stopper 320. In this way, the reliability of the locking of the case 20 by the second mounting members 330 and the stability of the mounting of the case 20 to the bracket 30 can be ensured by the third stopper 310 and the fourth stopper 320.

[0196] One embodiment of the present invention further provides a battery 10 which may include a battery cell 100 and a case 20 as described in each of the above embodiments for housing the battery cell 100.
