[0002] Energy conservation and emission reduction are the cornerstones of the sustainable development of the automotive industry. In this 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 a key factor in their development.
[0003] In the development of battery technology, in addition to improving the performance of the battery itself, the installation stability of the battery is also an issue that should not be ignored. Therefore, how to improve the installation stability of the battery is an urgent technical problem 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 consumption device that can enhance the mounting stability of the battery.
[0005] On a first side, a battery case is provided that includes a case body for accommodating a battery cell, and a first stopper installed on one side of a first wall of the case body away from the battery cell, the first wall being perpendicular to a first direction, the first direction being parallel to the traveling direction of the power consumption device after the case is attached to the power consumption device, and the first stopper being for limiting relative displacement of the case along the first direction.
[0006] According to the technical solution of an 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 a first direction. After the case is attached to the power consumption device, the first direction is parallel to the traveling 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 along the first direction on the power consumption device, that is, the first stopper can generate an acting force on the power consumption device along the traveling direction and the opposite traveling direction of the power consumption device, thereby limiting the relative displacement of the case to the traveling direction and the opposite traveling direction of the power consumption device, improving the mounting stability of the case to the traveling direction and the opposite traveling direction of the power consumption device, reducing the impact of the power consumption device in a traveling state on the battery and its case, and ensuring 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 of the case along a second direction, the second direction being 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 an acting force along a second direction on the power consumption device, that is, the second stopper can generate an acting force along the gravity direction and the anti-gravity direction on the power consumption device, thereby limiting the relative displacement of the case along the gravity direction and the anti-gravity direction, and 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 mounted on the first wall and movable along the first direction, and a buffer block mounted between the first stop block and the first wall and used to provide a buffer distance of the first stop block along the first direction.
[0010] According to the technical solution of this embodiment, when the case is attached to the power consuming device, the buffer block and the first stop block are installed in cooperation with each other, so that the first stop block can move into the case along the first direction, and the first stop block does not bring about too much installation resistance force, and the case can be conveniently attached to the power consuming device. Furthermore, after the case is attached to the power consuming device, the first stop block compresses the buffer block to put the buffer block in a compressed state, thereby providing an elastic acting force to the first stop block, so that the first stop block is tightly pressed against the power consuming device in the first direction, and the installation stability of the case along the first direction, i.e., the installation stability of the case along the running direction and anti-running direction of the power consuming device.
[0011] In some possible embodiments, the first stopper further includes a first fixing member, the first stop block being mounted to 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 the 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 relatively displaced in the first direction by the buffer block, which 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 a first end of the first stop block, which is an end of the first stop block facing in an antigravity direction.
[0014] According to the technical solution of this embodiment, when the case is attached to the power consumption device in the anti-gravity direction, it can be gradually moved toward 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 the case is attached to the power consumption device, so that the case can be attached to the power consumption device more conveniently.
[0015] In some possible embodiments, the second stopper is a resilient stop block, which is compressed to abut against the power consumer after the case is attached to the power consumer.
[0016] According to the technical solution of this embodiment, the second stopper is an elastic stop block, so that after the case is attached to the power consumption device, the elastic stop block is compressed and abuts against the power consumption device, and an elastic force exists between the elastic stop block in the compressed state and the power consumption device, and the elastic stop block is tightly pressed against the power consumption device in the second direction, thereby ensuring the mounting stability of the case along the second direction, that is, ensuring the mounting stability of the case along the gravity direction and anti-gravity direction of the power consumption device.
[0017] In some possible embodiments, a chamfer structure is provided at a first end of the resilient stop block, which is the end facing the antigravity direction.
[0018] According to the technical solution of this embodiment, when the case is attached to the power consuming device along the anti-gravity direction, the first end of the elastic stop block facing the anti-gravity direction contacts the power consuming device first and acts on the power consuming device, and the chamfer structure is provided on the first end of the elastic stop block, which makes it easier for the first end of the elastic stop block to be compressed by the power consuming device, and compared with the sharp corner structure, the chamfer structure can avoid stress concentration and prolong the service life of the elastic stop block. In addition, the chamfer structure can also improve the aesthetics of the elastic stop block.
[0019] In some possible embodiments, the first wall is provided with a receiving area for receiving the first stopper.
[0020] According to the technical solution of this embodiment, by setting up an accommodation area on the first wall of the case to accommodate the first stopper, the installation space of the first stopper can be saved, and meanwhile the accommodation area can also protect the first stopper so as to prevent it from being damaged by external influences and improve the service life of the first stopper in the case.

Furthermore, if the first stopper and the second stopper are adjacently installed on the same first wall, the acting forces between the first stopper and the power consuming device and the second stopper will be more concentrated, which can further improve the mounting stability of the case to the power consuming device, and since the first stopper and the second stopper are adjacently installed, the installation and repair of the first stopper and the second stopper are also convenient.

Therefore, after the battery case is attached to the bracket body of the power consumption device, the third stopper can generate an acting force on the case along the first direction, that is, the third stopper can generate an acting force on the case along the traveling direction and anti-traveling direction of the power consumption device, thereby limiting the relative displacement of the case along the traveling direction and anti-traveling direction of the power consumption device, improving the mounting stability of the case along the traveling direction and anti-traveling direction of the power consumption device, reducing the impact of the power consumption device in a traveling state on the battery and its case, and ensuring the normal operation of the battery and the power consumption device in which it is located.

[0033] In some possible embodiments, after the battery case is attached to the bracket body, the groove structure is adapted to receive a second stopper of the case to limit relative displacement of the case along the second direction.
[0034] According to the technical solution of this embodiment, the groove structure can be aligned with the second stopper on the battery case, and the groove structure can accommodate the second stopper and be tightly pressed against the second stopper, thereby realizing tight clamping of the case to the bracket body in the second direction, and improving the mounting stability of the bracket body of the case along the gravity direction and anti-gravity direction.
[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.

Furthermore, if the third stopper and the fourth stopper are adjacently installed on the same first beam, the acting forces between the third stopper and the fourth stopper and the case will be more concentrated, which can further improve the mounting stability of the case to the bracket, and since the third stopper and the fourth stopper are adjacently installed, the installation and repair of the third stopper and the fourth stopper are also convenient.

[0052] The terms indicating directions used in the following description are not intended to limit the specific structure of the present application, and are all directions shown in the drawings. In the description of the present application, as further explained, the terms "attached", "connected" and "connected" should be understood in a broad sense unless otherwise clearly defined or limited, and may refer to, for example, fixedly connected, detachably connected, or integrally connected, and may also refer to direct connection or connection via an intermediate object. Those skilled in the art can understand the specific meaning of the above terms in the present application based on the specific circumstances.
[0053] In this application, the term "and / or" is used only to describe the relationship between related objects and indicates that three types of relationships may exist, for example, A and / or B indicates three situations: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the symbol " / " in this document generally indicates that the related objects before and after it have an "or" relationship.
[0054] All technical and scientific terms used in this application have the same meaning as commonly understood by those skilled in the art unless otherwise defined, and the terms used in the specification of the application in this application are intended to describe specific embodiments only, without limiting the present application, and the terms "comprise" and "have" and any variations thereof described in the specification, claims and the above attached drawings of this application are intended to include non-exclusive inclusions. The terms "first" and "second" in the specification, claims and the above attached drawings of this application are intended to distinguish different objects only, and are not intended to describe a specific order or primary relationship.
[0055] When the present application refers to an "embodiment," it means that a particular feature, configuration, or characteristic described based on the embodiment may be included in at least one embodiment of the present application. When the term appears in various places in the specification, it does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. It is clearly or implicitly understood by those skilled in the art that the embodiment described herein may be combined with other embodiments.
[0056] In the present application, the battery cell may include a lithium ion secondary battery, a lithium ion primary battery, a lithium sulfur battery, a sodium lithium ion battery, a sodium ion battery, or a magnesium ion battery, etc., but is not limited to the embodiments of the present application. The battery cell may be a cylinder, a flat body, a rectangular parallelepiped, or other shape, etc., but is not limited to the embodiments of the present application. Battery cells are generally divided into three types, such as a columnar battery cell, a rectangular parallelepiped battery cell, and a pouch-type battery cell, depending on the packaging method, but is not limited to the embodiments of the present application.
[0057] The battery described in the embodiments of the present application represents a single physical module that includes one or more battery cells to provide higher voltage and capacity. For example, the battery described in the present application may include a battery module, 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 objects from affecting the charging or discharging of the battery cells.
[0058] In the development of battery technology, various design factors such as the battery's energy density, cycle life, charge / discharge capacity, charge / discharge rate, and safety performance must be considered simultaneously, and the battery installation stability must also be taken into account.
[0059] Specifically, in the application process, the battery is generally installed in the power consumption device to provide electrical energy to the power consumption device, and if the battery is not firmly attached to the power consumption device and is not stable, a certain external force will be applied to the battery when the power consumption device is in a moving state, especially in a moving state with acceleration, causing the battery to displace relative to the power consumption device, and in severe cases, the battery may come off from the fixed mounting position, affecting the electrical connection between the battery and the power consumption device as well as the performance of the battery itself, and ultimately causing the power consumption device to operate abnormally, resulting in a certain danger.
[0060] In view of the above, the present application provides a battery case used to accommodate a battery cell and including a first stopper, which is for limiting the relative displacement of the battery along the travel direction of the power consuming device after the case is attached to the power consuming device. In contrast, the present application also provides a bracket for a power consuming device, used to mount a battery of the power consuming device and including a third stopper, which is for limiting the relative displacement of the battery along the travel direction of the power consuming device after the battery case is attached to the power consuming device.
[0061] In some application scenarios, the power consumption device generally generates motion along its running direction and may generate motion with acceleration, which has a significant impact on the battery. By installing a first stopper on the battery case and / or installing 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 running direction of the power consumption device, can be enhanced, and the normal operation of the battery and the power consumption device in which it is located can be ensured.
[0062] The technical solutions described in the embodiments of the present application are all applicable to various power consuming devices that use batteries, such as electric vehicles, electric toys, electric tools, ships, and spacecraft, etc., for example, spacecraft including airplanes, rockets, spaceplanes, and spaceships, etc.
[0063] It will be understood that the technical solutions described in the embodiments of the present application are not limited to application to the various power consumption devices mentioned above, but may be applied to any apparatus or device that uses a battery. For convenience of explanation, the following embodiments will all be described using an electric vehicle as an example.
[0064] For example, FIG. 1 shows a structural schematic diagram of a vehicle 1 according to an embodiment of the present application, 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 type 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 may be installed at the bottom of the vehicle 1, or at the front or rear of the vehicle body. The battery 10 can be used to supply power to the vehicle 1, for example, the battery 10 can be used as an operating power source for the vehicle 1, and can be used for the circuit system of the vehicle 1, for example, as the power required to operate during starting, navigation, and driving the vehicle 1. In another embodiment of the present application, the battery 10 can not only be the operating power source of the vehicle 1, but also can be used as a driving power source for the vehicle 1 to replace or partially replace fuel oil or natural gas to provide driving power to the vehicle 1.
[0065] In order to meet different power utilization requirements, a battery may include multiple battery cells, among which the multiple battery cells can be connected in series, parallel, or mixed, where mixed connection means a mixture of series and parallel connections. The battery may be referred to as a battery pack. Optionally, a battery module may be first formed from the multiple battery cells through series, parallel, or mixed connections, and then a battery may be formed from the multiple battery modules through series, parallel, or mixed connections. That is, a battery may be formed directly from the multiple battery cells, or a battery module may be formed and then a battery may be formed from the battery module.
[0066] For example, Fig. 2 shows a structural schematic diagram of a battery 10 according to an embodiment of the present application, where 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) having a hollow structure, where the plurality of battery cells 100 are housed in the case body 200. As shown in Fig. 2, the case body 200 may include two parts, where the first part 2100 and the second part 2200 are respectively referred to as a first part 2100 and a second part 2200, and the first part 2100 and the second part 2200 are integrally engaged with each other. The shapes of the first part 2100 and the second part 2200 may be determined according to the shape of the combination of the plurality of battery cells 100, and each may have one opening. For example, the first part 2100 and the second part 2200 may both be hollow rectangular parallelepipeds with only one surface being an opening, with the opening of the first part 2100 and the opening of the second part 2200 facing each other, and the first part 2100 and the second part 2200 engaging with each other to form the case body 200 having a closed cavity. A plurality of battery cells 100 are combined by being connected in parallel, series or mixed with each other, and then placed in the case body 200 formed after the first part 2100 and the second part 2200 are engaged with each other.
[0067] Optionally, the battery 10 may further include other structures, which will not be described in detail here. For example, the battery 10 may further include a bus bar for realizing an electrical connection between the multiple battery cells 100, such as a parallel connection, a series connection, or a mixed connection. Specifically, the bus bar can realize an electrical connection between the battery cells 100 by connecting the electrode terminals of the battery cells 100. Furthermore, the bus bar 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 taken out through the case via a conductive mechanism. Optionally, the conductive mechanism may belong to the bus bar.
[0068] The number of battery cells 100 can be set to any value according to different power requirements. Multiple battery cells 100 can be connected in series, parallel or mixed connection to achieve large capacity or output. Since there may be a large number of battery cells 100 included in each battery 10, the battery cells 100 may be grouped for easy installation, and each group of battery cells 100 constitutes a battery module. The number of battery cells 100 included in a battery module is not limited and may be installed as needed.
[0069] In order to conveniently mount the battery 10 on the vehicle 1, Fig. 3 shows a structural schematic diagram of a bracket body 300 mounted on the vehicle 1. The case body 200 of the battery 10 can be mounted on the bracket body 300 so as to realize mounting of the battery 10 on the vehicle 1. In some embodiments, the bracket body 300 can be mounted on the chassis of the vehicle 1 so as to facilitate mounting or replacing the battery 10 mounted on the bracket body 300. In other embodiments, the bracket body 300 can be mounted on other positions on the battery 10, and the embodiments of the present application are not limited thereto.
[0070] In an embodiment of the present application, the bracket body 300 may include multiple beams, which are arranged to surround and form an accommodation space to accommodate at least one of the above-mentioned batteries 10, specifically, to accommodate at least one case body 200 of the at least one of the above-mentioned batteries 10, and to mount the 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, in which the pair of second beams 302 are installed opposite each other, and at least one first beam 301 is installed perpendicular to the extension direction of the second beams 302 and connected to the pair of second beams 302.
[0072] 3, the bracket body 300 includes three first beams 301, in which two first beams 301 are respectively connected to both ends of the pair of second beams 302, and another one 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 the three first beams 301 and the pair of second beams 302, and the first spaces 3100 and second spaces 3200 can be used to accommodate the case bodies 200 of two batteries 10, respectively, and the sizes thereof can be correspondingly designed to fit the sizes of the case bodies 200.
[0073] Of course, in other embodiments, the bracket body 300 may include other quantities of first beams 301, for example, the bracket body 300 only includes one first beam 301 connected to the middle of the pair of second beams 302, and in this embodiment, the space between the pair of second beams 302 can be divided into two symmetrical spaces for accommodating the case bodies 200 of two batteries 10. For further example, the bracket body 300 may include two first beams 301 respectively connected to both ends of the pair of second beams 302 and interconnected to form a frame-shaped structure, and the space in the frame-shaped structure is used to accommodate the case body 200 of one battery 10. For further example, the bracket body 300 may include four or more first beams 301, and the space between the pair of second beams 302 can be divided into three or more partial spaces for correspondingly accommodating the case bodies 200 of three or more batteries 10. The embodiment of the present application does not limit the specific number of the first beams 301 in the bracket body 300 .
[0074] Optionally, in order to conveniently attach the bracket body 300 to the vehicle 1, the extension directions of the first beam 301 and the second beam 302 may be parallel to the length and width directions of the vehicle 1, respectively, thereby saving space required for attaching the bracket body 300 to the vehicle 1.
[0075] Based on the embodiment of the present application shown in FIG. 2, FIG. 4 shows a schematic configuration diagram of the case 20 of the battery 10 provided in the embodiment of the present application.
[0076] As shown in FIG. 4, the case 20 of the battery 10 includes a case body 200 for accommodating the battery cells 100 (not shown in FIG. 4), and a first stopper 210 installed on one side of a first wall 201 of the case body 200 away from the battery cells 100, where the first wall 201 is perpendicular to a first direction x, the first direction x is parallel to the traveling direction of the power consumption device after the case 20 is attached to the power consumption device, and the first stopper 210 is for limiting relative displacement of the case 20 along the first direction x.
[0077] For example, the power consumption device in the embodiments of the present application may be the vehicle 1 described above, and after the battery 10 is installed in the vehicle 1, the first direction x may be parallel to the running direction of the vehicle 1. In some embodiments, the running direction of the vehicle 1 may be parallel to its length, i.e., after the battery 10 is installed in the vehicle 1, the first direction x may be parallel to the length of the vehicle 1.
[0078] Of course, the power consumption device in the embodiment of the present application may be other types of power consumption devices other than vehicle 1, and it may have a motion state, and the direction of the motion state may be referred to as the driving direction in the embodiment of the present application.
[0079] 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 are engaged with each other. Therefore, in the embodiment of the present application, the first stopper 210 installed on the first wall 201 may be independently installed on the first part 2100 of the case body 200, independently installed on the second part 2200 of the case body 200, or may be 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 FIG. 4, the first stopper 210 is installed on one part of the case body 200.
[0080] In the embodiment of the present application, the first stopper 210 is disposed on one side of the first wall 201 of the case body 200, which is away from the battery cell 100. As can be understood, the battery cell 100 is accommodated in a cavity inside the case body 200, and one side of the case body 200 close to the battery cell 100 can be understood as the inside of the case body 200, whereas one side of the case body 200 away from the battery cell 100 can be understood as the outside of the case body 200. Thus, one side of the first wall 201 of the case body 200 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 disposed on the outside of the first wall 201 can easily interact with the power consumption device, limiting the relative displacement of the case 20 with the power consumption device.
[0081] Furthermore, 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 an acting force along the first direction x on the power consumption device to limit the relative displacement of the case 20 to the power consumption device along the first direction x.
[0082] For a power consuming device capable of moving, its main motion state may be a running state, and in the running state, its motion manner may change in various ways, for example, for a vehicle, the running state may include different motion states such as starting, accelerating, decelerating, braking, etc. In the running state in which the motion manner of the power consuming device changes in various ways, the elements inside the power consuming device, such as a battery, are also significantly 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, which is away from the battery cell 100, and the first wall 201 is perpendicular to the first direction x. After the case 20 is attached to the power consumption device, the first direction x is parallel to the traveling direction 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 traveling direction and the opposite traveling direction of the power consumption device, thereby restricting the relative displacement of the case 20 to the traveling direction and the opposite traveling direction of the power consumption device, improving the mounting stability of the case 20 along the traveling direction and the opposite traveling direction of the power consumption device, reducing the impact of the traveling power consumption device on the battery 10 and its case 20, and ensuring the normal operation of the battery 10 and the power consumption device in which it is located.
[0084] As is necessary to explain, the first wall 201 in the embodiment of the present application may include a main structure and an auxiliary structure, in which the main structure can be approximately understood as a wall-like structure, and an auxiliary structure such as a convex portion or a concave portion may be provided on a surface of a part of the wall-like structure so as to conveniently install components related to the case 20 on the first wall 201. The first stopper 210 in the embodiment of the present application may be directly installed on the main wall-like structure of the first wall 201, or may be installed on an auxiliary structure such as a convex portion or a concave portion on the main wall-like structure. For example, in the embodiment shown in FIG. 4, the first stopper 210 is installed on an auxiliary convex portion protruding outward from the first wall 201 along the first direction x on the main wall-like structure of the first wall 201. For convenience of explanation, the main structure and the auxiliary structure in the first wall 201 will not be distinguished from each other and will be collectively referred to as the first wall 201 hereinafter.
[0085] Regarding the first stopper 210, FIG. 5 shows a schematic perspective configuration diagram, and FIG. 5 may be a local enlarged view of part A in FIG. 4. FIG. 6 shows a schematic exploded view of the first stopper 210. FIG. 7 shows a schematic cross-sectional view of the first stopper 210 along the xz plane in FIG. 5. In this case, the xz plane is a plane specified by the x direction and the z direction, the x direction is the first direction in the above-mentioned embodiment of the present application, 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 be parallel to the gravity direction, and the z direction includes the anti-gravity direction z1 and the gravity direction z2. For ease of display and understanding, FIG. 5 and some of the accompanying drawings below further show the y direction perpendicular to the x direction and the z direction, and these three directions jointly 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 movable along the 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 for the first stop block 211 along the first direction x.
[0087] Specifically, after the case 20 is attached to the power consumption device, the first stop block 211 of the first stopper 210 acts against the power consumption device to prevent the case from being displaced relative to the power consumption device. In order 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, for example, a wear-resistant material including, but not limited to, polyoxymethylene (POM) material having high mechanical strength and rigidity.
[0088] In order to conveniently attach the case 20 to the power consuming device, the first stopper 210 in the embodiment of the present application further includes a buffer block 212 that is installed between the first stop block 211 and the first wall 201 and 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 is not fixed to the first wall 201, but by installing the buffer block 212, there can be a buffer distance in the first direction x.
[0089] Optionally, in the embodiment of the present application, the buffering distance provided by the buffer block 212 may be determined according to a thickness size in the first direction x of the buffer block 212. For example, in an initial state, the buffer block 212 has a thickness in the first direction d1, and in a maximum compressed state of the buffer block, the thickness in the first direction d2, 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] Optionally, the buffer block 212 can be made of an elastic material, including but not limited to a polyurethane (PU) material, which can be used to make a foam or plastic sponge 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 the case 20 is attached to the power consuming device, the buffer block 212 and the first stop block 211 are installed in cooperation with each other, so that the first stop block 211 can move inside the case 20 along the first direction x, and the first stop block 211 does not bring about too much attachment resistance force, so that the case 20 can be attached to the power consuming device conveniently. Furthermore, after the case 20 is attached to the power consuming device, the first stop block 211 compresses the buffer block 212 to put the buffer block 212 in a compressed state, thereby providing an elastic acting force to the first stop block 211, so that the first stop block 211 is tightly pressed against the power consuming device in the first direction x, and thus ensuring the attachment stability of the case 20 along the first direction x, i.e., ensuring the attachment stability of the case 20 along the running direction and anti-running direction of the power consuming device.
[0092] Optionally, referring to Figures 5 to 7, the first stopper 210 in the embodiment of the present application may further include a first fixing member 213, and the first stop block 211 can be installed on the first wall 201 by the first fixing member 213, and the first fixing member 213 is for providing a buffer space along the first direction x between the first stop block 211 and the buffer block 212.
[0093] Specifically, in the embodiment of the present application, the first fixing member 213 does not directly fix the first stop block 211 to the first wall 201, but installs the first stop block 211 on the first wall 201 at a limited position, and provides a buffer space along the first direction x for the first stop block 211 and the buffer block 212. When the case 20 is attached to the power consumption device, the first stop block 211 can generate a 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 there is a certain buffer space between the head of the screw and the first wall 201 in the first direction x, and a first stop block 211 and a 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, the first stop block 211 and the buffer block 212 generate a relative displacement between the screw head and the first wall 201 in the first direction x.
[0095] In the embodiment shown in FIG. 6 , the first fixing member 213 may be a shoulder screw, which has a stepped structure, in which a first step is fixed to the first wall 201, and a second step and a screw head cooperate with the first stop block 211 and the buffer block 212 to provide a buffer space for the first stop block 211 and the buffer block 212.
[0096] Specifically, when the case 20 is not attached to the power consumption device, the buffer block 212 is in a first state by the action of the first fixing member 213 and the first stop block 211, the first state may be an initial uncompressed state or a lightly compressed compressed state, in the 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 of the first stop block 211 along the first direction x according to 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 generate a relative displacement in the first direction x by the buffer block 212. Therefore, the first stop block 211 does not bring about an excessive mounting resistance, and the case 20 can be easily mounted on the power consuming device. In addition, after the case 20 is mounted on the power consuming device, the mutual cooperation between the first stop block 211 and the buffer block 212 can ensure the mounting stability of the case 20 along the first direction, i.e., the mounting stability of the case 20 along the running direction and the counter-running direction of the power consuming device can be ensured.
[0098] Optionally, as shown in Figures 5 and 6, in the embodiment of the present application, the entire outer shape of the first stop block 211 may be approximately a block shape, and a mounting position may be provided in the middle thereof, and the first fixing member 213 is mounted on the first wall 201 in a position limited by the mounting position in the middle of the first stop block 211, and this embodiment can achieve a more preferable position fixing and limiting effect than mounting the first fixing member 213 at another position of the first stop block 211. Of course, the first fixing member 213 may be mounted at another position of the first stop block 211 according to a specific application scene or need, as long as it provides a buffer space between the first stop block 211 and the buffer block 212 and allows the first stop block 211 to generate a relative displacement in the first direction x by the buffer block 212, and the embodiment of the present application does not limit the specific position of the first fixing member 213.
[0099] 6, in the embodiment of the present application, the buffer block 212 may have an approximately block-shaped overall outer shape in order to increase the contact area between the buffer block 212 and other components and the mounting stability thereof. A through-hole is correspondingly provided in the center of the buffer block 212, and the first fixing member 213 mounts the buffer block 212 on the first wall 201 through the through-hole.
[0100] Optionally, in some application scenarios, the case 20 may be attached to the power consuming device facing the anti-gravity direction z1, for example, the power consuming device is a vehicle 1, and the case 20 can be lifted and attached to the chassis of the vehicle 1, i.e., the case 20 is attached to the 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 application, and the first end 2111 of the first stop block 211 is an end of the first stop block 211 facing the antigravity direction z1. Therefore, when the case 20 is attached to the power consuming device in the antigravity direction z1, it can be gradually moved toward the antigravity direction z1 with the help of the first end 2111 having a wedge angle of the first stop block 211, and the first end 2111 can guide and position the case 20 when the case 20 is attached to the power consuming device, making it more convenient to attach the case 20 to the power consuming device.
[0102] Optionally, and further referring to FIG. 6 and FIG. 7, in this embodiment of the present application, the first wall 201 is provided with a receiving area 2011 capable of receiving the first stopper 210. As shown in FIG.
[0103] Specifically, the receiving area 2011 may be suitable for the first stopper 210. For example, the receiving area 2011 may include a quadrilateral groove to properly receive the first stop block 211 of the first stopper 210. For example, the depth of the quadrilateral groove needs to be greater than the thickness of the buffer block 212 in the first direction x, so that the quadrilateral groove has a space to receive the buffer block 212. For example, if the first fixing member 213 is a screw, the receiving area 2011 may further include a screw hole to properly attach the screw.
[0104] According to the technical solution of the embodiment of the present application, an accommodating area 2011 is provided on the first wall 201 of the case 20 to accommodate the first stopper 210, thereby saving the installation space of the first stopper 210; meanwhile, the accommodating area 2011 can also protect the first stopper 210 from being damaged by external influences, and improve the service life of the first stopper 210 in the case 20.
[0105] FIG. 8 shows a schematic plan view along the xy plane of the case 20 of the battery 10 provided in the embodiment of the present application.
[0106] Alternatively, as shown in FIG. 8, the case 20 may include a plurality of the first stoppers 210 that can be installed in a distributed manner on two first walls 201 of the case body 200 that are parallel to each other.
[0107] Specifically, after the case 20 is attached to the power consuming device, the two first walls 201 are both perpendicular to the first direction x, i.e., perpendicular to the traveling direction of the power consuming device. In the embodiment of the present application, a plurality of first stoppers 210 are provided and distributed on the two first walls 201 due to the space between the two first walls 201, so that the first stoppers 210 on the two first walls 201 of the case 20 can all generate an acting force on the power consuming device along the first direction x, so that the case 20 can be tightly sandwiched against the power consuming device in the first direction x, and the relative displacement of the case 20 and the power consuming device along the first direction x can be further restricted, thereby improving the attachment stability of the case 20 to the power consuming device.
[0108] As is necessary to explain, in the present application, two first walls 201 parallel to each other can be understood to mean two first walls 201 whose main wall-like structures are parallel to each other, and this parallelism does not mean absolute parallelism, but may be approximately parallelism.
[0109] Optionally, the number of first stoppers 210 installed on the two first walls 201 may be equal or unequal. Optionally, multiple first stoppers 210 may be aligned on the first wall 201 along the y direction.
[0110] As an example, two first stoppers 210 can be installed on one first wall 201, and these two first stoppers 210 are distributed and installed in both end regions of the one first wall 201 along the y direction, that is, distributed and installed in two corner regions of the case body 200. Only one first stopper 210 can be installed on the other first wall 201, and the one first stopper 210 can be installed in the central region of the other first wall 201 along the y direction.
[0111] As another example, as shown in FIG. 8, each of the two first walls 201 has one first stopper 210 installed at both ends in the y direction, that is, four first stoppers 210 are distributed in the four corner regions of the case body 200.
[0112] According to the technical solution of the embodiment of the present application, 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 of the power consumption device, and comprehensively improving the mounting stability of the case 20 to the power consumption device.
[0113] FIG. 9 shows another schematic diagram of the case 20 of the battery 10 provided in the embodiment of the present application.
[0114] Optionally, as shown in FIG. 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, where the second direction z is parallel to the direction of gravity after the case 20 is attached to the power consumption device.
[0115] As can be understood, the battery cell 100 is accommodated in a cavity inside the case body 200, and one side of the case body 200 close to the battery cell 100 can be understood to be the inside of the case body 200, whereas one side of the case body 200 away from the battery cell 100 can be understood to be the outside of the case body 200. Therefore, in the embodiment of the present application, the second stopper 220 is disposed 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, i.e., limit 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. 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 on the power consumption device, i.e., the second stopper 220 can generate an acting force along the gravity direction z2 and the antigravity direction z1 on the power consumption device, thereby limiting the relative displacement of the case 20 along the gravity direction z2 and the antigravity direction z1, and further improving the attachment stability of the case 20 to the power consumption device, so as to ensure the normal operation of the battery 10 and the power consumption device in which it is located.
[0117] Optionally, the second stopper 220 provided in the embodiments of the present application can be installed on the outside of any wall of the case body 200, the purpose of which is that after the case 20 is attached to the power consumption device, the second stopper 220 can abut against the power consumption device and generate an acting force on the power consumption device along the gravity direction z2 and the anti-gravity direction z1, and the embodiments of the present application do 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 Fig. 9, the second stopper 220 can be similarly installed on the first wall 201 of the case body 200 in the embodiment of the present application described above. In this case, Fig. 10 shows a schematic perspective configuration diagram of the second stopper 220, and Fig. 10 may be a local enlarged view of part B in Fig. 9. Fig. 11 is a schematic cross-sectional view of the second stopper 220 taken along the xz plane in Fig. 10.
[0119] For example, in the embodiment shown in Figures 10 and 11, the first wall 201 may include an extension portion 2012 extending away from the battery cell 100 in the case body 200 along the first direction x and used to position the second stopper 220.
[0120] Specifically, the first wall 201 includes an extension portion 2012 extending toward the outside of the case body 200 along the first direction x, and after the second stopper 220 is attached to the extension portion 2012 in this manner, it can be installed facing the power consumption device in the second direction z and can generate an interaction with the power consumption device in the second direction z.
[0121] 9, it can be understood that the case body 200 may further include a second wall 202 perpendicular to the third direction y (i.e., the y direction shown in the figure) in addition to including the first wall 201. If the second stopper 220 is installed on the second wall 202, the second wall 202 may similarly include an extension portion in order to install the second stopper 220, and the extension portion of the second wall 202 may extend toward the outside of the case body 200 along the y direction.
[0122] It can also be understood that the case body 200, in addition to including the first wall 201 and the second wall 202, may further include a third wall 203 perpendicular to the second direction z, in which case the second stopper 220 can be installed directly on the outside of the third wall 203, for the purpose of interacting with the power consumption device.
[0123] Optionally, in some embodiments, the second stopper 220 can be an elastic stop block, and after the case 20 is attached to the power consuming device, the elastic stop block is compressed and abuts against the power consuming device, so that there is an elastic acting force between the elastic stop block in the compressed state and the power consuming device, and the elastic stop block is tightly pressed against the power consuming device in the second direction z to ensure the mounting stability of the case 20 along the second direction z, i.e., to ensure the mounting stability of the case 20 along the gravity direction z2 and the anti-gravity direction z1 of the power consuming device.
[0124] Optionally, the material of the elastic stop block in the embodiments of the present application includes, but is not limited to, a rubber material which not only has elasticity but also has a certain wear resistance and strength. After the elastic stop block made of this rubber material is attached to the power consumption device, it has little impact on the power consumption device, ensures the stability of the attachment between the case 20 and the power consumption device, and can avoid wear and tear on the power consumption device caused by vibration of the case 20 and reduce the risk of rust on the power consumption device.
[0125] Optionally, to secure the attachment of the case 20 to the power consuming device, the compression amount of the elastic stop block can be made to be equal to or greater than a predetermined threshold, so as to ensure that the acting force between the elastic stop block and the power consuming device reaches or exceeds a predetermined threshold after the case 20 is attached to the power consuming device. For example, the compression amount of the elastic stop block can be equal to or greater than 3 mm.
[0126] Optionally, in the embodiment shown in Figures 10 and 11, based on the second stopper 220 being an elastic stop block, a chamfer structure is provided on a first end 2201 of the elastic stop block, which is the end of the elastic stop block facing the anti-gravity direction z1.
[0127] When the housing 20 is attached to the power consuming device along the anti-gravity direction z1, the first end 2201 of the elastic stop block facing the anti-gravity direction will first contact and act on the power consuming device, and according to the technical solution of the embodiment of the present application, a chamfer structure is provided on the first end 2201 of the elastic stop block, which makes it easier for the first end 2201 of the elastic stop block to be compressed by the power consuming device, and compared with a sharp corner structure, the chamfer structure can avoid stress concentration and extend the service life of the elastic stop block. In addition, the chamfer structure can also improve the aesthetics of the elastic stop block.
[0128] 10 and 11 show, by way of example, a method for attaching the second stopper 220 to the extension portion 2012. FIG.
[0129] Optionally, the extension 2012 includes an accommodation area for accommodating the second stopper 220, so that the second stopper 220 can be attached and installed to the extension 2012. Furthermore, if the second stopper 220 is an elastic stop block, the elastic stop block has a protrusion at a location facing the extension 2012, and the extension 2012 has an engagement groove for engaging the protrusion, so that the elastic stop block can be stably attached and installed to the extension 2012.
[0130] Of course, in addition to the mounting method in the embodiment shown in Figures 10 and 11, the second stopper 220 can be installed and attached to the extension portion 2012 in any other manner, such as by mounting it to the extension portion 2012 using a fixing member, and the embodiments of the present application are not specifically limited thereto.
[0131] Optionally, the centre of the first stopper 210 and the centre of the second stopper 220 lie in a plane defined by the first direction x and the second direction z, ie a first plane parallel to the xz plane.
[0132] In some embodiments, the center of the first stopper 210 may be understood to be the geometric center or center of gravity of any module in the first stopper 210, for example, the center of the first stopper 210 may be the geometric center or center of gravity of said first stop block 211. Similarly, the center of the second stopper 220 may be understood to be the geometric center or center of gravity of any module in the second stopper 220, for example, the center of the second stopper 220 may be the geometric center or center of gravity of said elastic stop block.
[0133] In this case, FIG. 12 is a schematic perspective view of the first stopper 210 and the second stopper 220 in the embodiment of the present application.
[0134] 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 extension portion 2012 in which the first region extends toward the outside of the case 20 along the first direction x. In addition, in this embodiment, the center of the first stopper 210 and the center 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 all 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 can be installed on one first wall 201 of the case body 200 and the second stopper 220 can be installed symmetrically on the other first wall 201 of the case body 200, and the center of the first stopper 210 and the center of the second stopper 220 may also be located on a first plane parallel to the xz plane.
[0136] According to the technical solution of the embodiment of the present application, the center of the first stopper 210 and the center of the second stopper 220 are both on a first plane parallel to the xz plane, and after the case 20 is attached to the power consuming device, the acting forces between the first stopper 210 and the power consuming device and the acting forces between the second stopper 220 and the power consuming device are concentrated on the same plane, which further improves the attachment stability of the case 20 to the power consuming device. Furthermore, if the first stopper 210 and the second stopper 220 are adjacently installed on the same first wall 201, the acting forces between the first stopper 210 and the second stopper 220 and the power consuming device will be more concentrated, which can further improve the attachment stability of the case 20 to the power consuming device, and since the first stopper 210 and the second stopper 220 are adjacently installed, the installation and repair of the first stopper 210 and the second stopper 220 is also convenient.
[0137] Further, referring to FIG. 12 , the case 20 may further include a first mounting member 230 installed on one side of the first wall 201 of the case body 200 away from the battery cell, 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 and installing the case 20 to the power consumption device, and the first stopper 210 may be installed adjacent to the first mounting member 230.
[0138] 12, the first attachment member 230 may be a locking part, whereas the power consuming device may be provided with a locking mechanism and a passage, the locking part moves along the passage, and the locking mechanism is arranged to lock the case 20 to the power consuming device when the locking part moves to a predetermined position along the passage. The locking mechanism may further be arranged to release the locking part and disengage the locking part from the passage, thereby unlocking the case 20 from the power consuming device.
[0139] After the case 20 is attached to the power consuming device by the first attachment member 230, the first stopper 210 can generate an acting force on the power consuming device along the traveling direction and counter-travel direction of the power consuming device, thereby limiting the relative displacement of the case 20, particularly the components around the first stopper 210 of the case 20, along the traveling direction and counter-travel direction of the power consuming device. Therefore, the stability of the components around the first stopper 210 of the case 20 is high, and according to the technical solution of the embodiment of the present application, the first attachment member 230 for locking the case 20 is installed adjacent to the first stopper 210, thereby improving the stability of the first attachment member 230 and further improving the attachment stability of the case 20 to the power consuming device.
[0140] Furthermore, as shown in FIG. 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, Fig. 13 shows a schematic perspective configuration diagram of the case 20 of the battery 10. Fig. 14 shows a schematic plan view of the case 20 in Fig. 13 along the xy plane.
[0142] As shown in Figures 13 and 14, the case 20 may include a plurality of the first stoppers 210 and a plurality of the second stoppers 220, in which the plurality of first stoppers 210 can be distributed and installed on two parallel first walls 201 in the case body 200, and the plurality of second stoppers 220 are installed adjacent to and correspond one-to-one with the plurality of first stoppers 210.
[0143] Optionally, the case 20 further includes a plurality of the above-mentioned first mounting members 230 that can be distributed and installed in the four corner regions of the case body 200 to ensure the stability of the locking mounting of the case 20.
[0144] 14, the plurality of first mounting members 230 are distributed in the four corner regions of the case body 200 and are installed on two parallel first walls 201. Furthermore, the plurality of first mounting members 230 may be installed adjacent to the first stopper 210 and the second stopper 220 so that the mounting stability of the first mounting members 230 and the case 20 can be ensured by the first stopper 210 and the second stopper 220.
[0145] Above, the relevant technical solutions of the case 20 of the battery 10 provided in the embodiment of the present application have been described with reference to Figures 4 to 14. Hereinafter, the relevant technical solutions of the bracket 30 for mounting the case 20 of the battery 10 provided in the embodiment of the present application will be described with reference to Figures 15 to 24.
[0146] Based on the embodiment of the present application shown in Figure 3 above, Figure 15 shows a schematic configuration diagram of the bracket 30 provided in the embodiment of the present application, where the bracket 30 is applicable to a power consuming device, which may be the power consuming device described in the embodiments shown in Figures 4 to 14 above, including but not limited to the vehicle 1 shown in Figure 1 above.
[0147] As shown in FIG. 15, the bracket 30 includes a bracket main body 300 for mounting a case 20 (not shown) of a battery 10 of a power consumption device for accommodating battery cells 100, and a third stopper 310 installed on one side of a first beam 301 of the bracket main body 300 closer to the case 20, the extension direction of the first beam 301 being perpendicular to a first direction x parallel to the traveling direction of the power consumption device, and the third stopper 310 for limiting 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 embodiments of the present application, reference may be made to the relevant description of the embodiment shown in Fig. 3 above. The attachment of the case 20 of the battery 10 to the power consumption device in the above-mentioned Figs. 4 to 14 can be understood as attaching the case 20 of the battery 10 to the bracket 30 in the embodiments of the present application below, and specifically, to the bracket body 300 of the bracket 30.
[0149] In this embodiment, the extension direction of the first beam 301 of the bracket body 300 is perpendicular to the first direction x, which is parallel to the traveling direction of the power consuming device. If the traveling direction of the power consuming device is the length direction of the power consuming device, in this embodiment, the extension direction of the first beam 301 is perpendicular to the length direction of the power consuming device, i.e., parallel to the width direction of the power consuming device.
[0150] Furthermore, in this embodiment of the present application, a third stopper 310 is provided on one side of the first beam 301 close to the case 20 for limiting the relative displacement of the case 20 along the first direction x.
[0151] For ease of understanding, in the embodiment of the present application, one side of the first beam 301 close to the case 20 may be referred to as the inside of the first beam 301, and the inside of the first beam 301 can form a space to accommodate the case 20.
[0152] Specifically, after the case 20 of the battery 10 is attached and housed in the bracket body 300, the third stopper 310 installed on the inside of the first beam 301 interacts with the case 20 to limit the relative displacement of the case 20 and the power consumption device of the battery 10 therein.
[0153] Furthermore, 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 stored in the bracket body 300, the third stopper 310 generates an acting force on the case 20 along the first direction x, thereby limiting the relative displacement of the case 20 in the bracket body 300 along the first direction x.
[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, which is close to the case 20 of the battery 10, and the extending direction of the first beam 301 is perpendicular to the first direction x which is parallel to the traveling 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, i.e., the third stopper 310 can generate an acting force on the case 20 along the traveling direction and anti-traveling direction of the power consumption device, thereby restricting the relative displacement of the case 20 along the traveling direction and anti-traveling direction of the power consumption device, improving the mounting stability of the case 20 along the traveling direction and anti-traveling direction of the power consumption device, reducing the impact of the traveling power consumption device on the battery 10 and its case 20, and ensuring the normal operation of the battery 10 and the power consumption device in which it is located.
[0155] Optionally, in an embodiment of the present application, after the case 20 of the battery 10 is attached to the bracket 30 of the power consumption device, the third stopper 310 installed on the bracket body 300 can cooperate with the first stopper 210 installed on the case body 200 in the above-mentioned embodiment of the present application, and the third stopper 310 can generate an acting force on the first stopper 210 along the traveling direction and counter-traveling direction of the power consumption device, thereby limiting the relative displacement of the case 20 along the traveling direction and counter-traveling direction of the power consumption device.
[0156] Regarding the third stopper 310, Fig. 16 shows a schematic perspective configuration diagram, which may be a local enlarged view of part C in Fig. 15. Fig. 17 shows a schematic exploded view of the third stopper 310. Fig. 18 shows a schematic cross-sectional view of the third stopper 310 along the xz plane in Fig. 16, in which the xz plane is a plane specified by the x direction and the z direction, the x direction is the first direction x in the above-mentioned embodiment of the present application, and the z direction may be parallel to the gravity direction, in which 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 having a wedge angle 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] 16 and 17, in the embodiment of the present application, the third stop block 311 may have an approximately solid overall outer shape and a mounting position may be provided in the middle thereof, and the second fixing member 312 may fixedly install the third stop block 311 to the first beam 301 through the mounting position in the middle of the third stop block 311, which can provide a more preferable fixing effect than installing the second fixing member 312 at another position of the third stop block 311. In this regard, the second fixing member 312 may include, but is not limited to, a screw and a nut, which can conveniently attach and detach the third stop block 311.
[0159] Specifically, after the case 20 is attached to the bracket 30, the third stop block 311 of the third stopper 310 acts against the case 20 to prevent the case 20 from being displaced relative to the case 20. In order 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, for example, a wear-resistant material including, but not limited to, a polyoxymethylene (POM) material having high mechanical strength and rigidity.
[0160] Optionally, in some application scenarios, the case 20 may be attached to the power consuming device facing the anti-gravity direction z1, for example, the power consuming device is a vehicle 1, and the case 20 can be lifted and attached to a bracket 30 on the chassis of the vehicle 1, i.e., the case 20 is attached to the bracket 30 on the vehicle 1 facing the anti-gravity direction.
[0161] In this application scenario, a wedge angle may be set on the end 3111 of the third stop block 311 facing the anti-gravity direction in the embodiment of the present application, so that when the case 20 is attached to the bracket 30, with the help of the end 3111 of the third stop block 311, it can be gradually moved toward the anti-gravity direction z1, and the end 3111 can guide and position the case 20 when the case 20 is attached to the bracket 30, making it more convenient to attach the case 20 to the bracket 30.
[0162] It should be noted that in the embodiment of the present application, the bracket 30 includes a third stopper 310 that can be aligned with the first stopper 210 of the case 20 in the embodiment 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 of the bracket 30 and the case 20 are exchanged with each other, after the case 20 is attached to the bracket 30, the first stopper 210 and the third stopper 310 can be aligned with each other, and the case 20 can be stably attached to the bracket 30.
[0163] However, the first stopper 210 has a somewhat complicated structure and requires a buffer block 212 to realize the buffering movement of the first stop block 211, and requires more frequent repair or replacement than the third stopper 310. Therefore, by installing the first stopper 210 on the case 20, it is possible to make it easier to repair and replace the first stopper 210.
[0164] FIG. 19 shows a schematic plan view of a bracket 30 provided in an embodiment of the present application.
[0165] Alternatively, as shown in FIG. 19, the bracket 30 may include a plurality of the third stoppers 310 that can be installed in a distributed manner on at least two first beams 301 that are parallel to each other in the bracket body 300 .
[0166] Specifically, in the embodiment of the present application, the extending directions of the at least two first beams 301 are all perpendicular to the first direction x, i.e., perpendicular to the traveling direction of the power consuming device. In the embodiment of the present application, a plurality of third stoppers 310 are provided and distributed on the at least two first beams 301 according to the space between the at least two first beams 301, so that the third stoppers 310 of the at least two first beams 301 in the bracket body 300 can all generate an acting force in the first direction x on the case 20, so that the case 20 is tightly sandwiched against the bracket body 300 in the first direction x, and the relative displacement of the case 20 in the bracket 30 in the first direction x can be further restricted, thereby improving the mounting stability of the case 20 to the power consuming device.
[0167] Optionally, in the embodiment of the present application, a plurality of third stoppers 310 may be further distributed at the four corner regions of the space for accommodating 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 bracket 30 at the four corner regions of the case 20, and comprehensively improving the mounting stability of the case 20 to the bracket 30 and the power consumption device in which it is located.
[0168] For example, in the embodiment shown in FIG. 19 , the bracket body 300 includes a first space 3100 and a second space 3200 for accommodating the cases 20, and a plurality of third stoppers 310 are distributed and installed in the four corner regions 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] FIG. 20 shows a schematic diagram of a bracket 30 provided in an embodiment of the present application.
[0170] Optionally, as shown in FIG. 20 , the bracket 30 provided in the embodiment of the present application may include a fourth stopper 320 that is installed on the bracket body 300 and is used to limit relative displacement of the case 20 along a second direction z parallel to the gravity direction.
[0171] Optionally, in the embodiments of the present application, the fourth stopper 320 can be installed on any beam of the bracket body 300, and in some embodiments, it can be installed on one side of the arbitrary beam of the bracket body 300 in the gravity direction, or on one side of the arbitrary beam of the bracket body 300 in the anti-gravity direction.
[0172] According to the technical solution of the embodiment of the present application, by installing a 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, i.e., the fourth stopper 320 can generate an acting force on the case 20 along the gravity direction z2 and the antigravity direction z1, thereby limiting the relative displacement of the case 20 along the gravity direction z2 and the antigravity direction z1, and further improving the mounting stability of the case 20 to the bracket 30, so as to ensure 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 Fig. 20, the fourth stopper 320 can be similarly installed on the first beam 301 of the bracket body 300 in the embodiment of the present application. In this case, Fig. 21 shows a schematic perspective configuration diagram of the fourth stopper 320, and Fig. 21 may be a locally enlarged view of part D in Fig. 20.
[0174] For example, in the embodiment shown in FIG. 21, the fourth stopper 320 is disposed on one side of the first beam 301 in the gravity direction z2, and includes a groove structure 321 with an opening facing the gravity direction z2.
[0175] When this embodiment is adopted, when the case 20 of the battery 10 is attached 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 come into contact with 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 realizing engagement between the groove structure 321 and the protruding member inside the case 20, thereby limiting the relative displacement of the case 20 in the bracket body 300, and improving the mounting stability of the case 20 to the bracket 30.
[0177] Optionally, in some embodiments, the groove structure 321 in the embodiments of the present application can be mutually aligned with the second stopper 220 in the above-mentioned embodiments of the present application, and the groove structure 321 can accommodate the second stopper 220 and be tightly pressed against the second stopper 220 to realize tight clamping of the bracket body 300 of the case 20 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] In addition to realizing tight clamping of the case 20 relative to the bracket body 300 in the second direction z, the groove structure 321 can also realize positional limitation of the case 20 relative to the bracket body 300 in the third direction y, thereby improving the mounting stability of the case 20 relative to the bracket body 300 along the third direction y.
[0179] In the embodiment of the present application, since the fourth stopper 320 needs to interact with the case 20, in order to prevent rust due to wear and tear caused by the case 20 and to maintain a tight clamping relationship with the case 20, the material of the fourth stopper 320 includes, but is not limited to, a material having wear resistance and rust resistance such as stainless steel, and the fourth stopper 320 can also achieve good close cooperation with the second stopper 220 of the case 20, such as an elastic stop block.
[0180] It should be noted that in the embodiment of the present application, the bracket 30 includes a fourth stopper 320 that can be aligned with the second stopper 220 of the case 20 in the embodiment 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 of the bracket 30 and the case 20 are exchanged with each other, after the case 20 is attached to the bracket 30, the second stopper 220 and the fourth stopper 320 can be aligned with each other, and the case 20 can be stably attached 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, it is possible to facilitate repair and replacement of the second stopper 220.
[0182] Optionally, the centre of the third stopper 310 and the centre of the fourth stopper 320 may lie in a first plane parallel to a plane defined by the first direction x and the second direction z.
[0183] Optionally, in some embodiments, the center of the third stopper 310 can be understood to be the geometric center or center of gravity of any module in the third stopper 310, for example, the center of the third stopper 310 can be the geometric center of the third stop block 311. Similarly, the center of the fourth stopper 320 can be understood to be the geometric center or center of gravity of any module in the fourth stopper 320, for example, the center of the fourth stopper 320 can be the geometric center of the groove structure 321.
[0184] In this case, FIG. 22 shows a schematic perspective configuration diagram of the third stopper 310 and the fourth stopper 320 in the embodiment of the present application.
[0185] 22, the third stopper 310 and the fourth stopper 320 may both be 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 both sides of the first beam 301 that are perpendicular to each other and adjacent to each other. In this embodiment, the center of the third stopper 310 and the center of 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 all 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 can be installed on one first beam 301 of the bracket body 300 and the fourth stopper 320 can 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 can also be located 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, and after the case 20 is attached to the bracket 30, the acting forces of the third stopper 310 and the case 20 and the acting forces of the fourth stopper 320 and the case 20 are concentrated on the same plane, which further improves the mounting stability of the case 20 to the bracket 30. Furthermore, if the third stopper 310 and the fourth stopper 320 are adjacently installed on the same first beam 301, the acting forces between the third stopper 310 and the fourth stopper 320 and the case 20 will be more concentrated, which can further improve the mounting stability of the case 20 to the bracket 30. In addition, since the third stopper 310 and the fourth stopper 320 are adjacently installed, the installation and repair of the third stopper 310 and the fourth stopper 320 is also convenient.
[0188] Furthermore, referring to FIG. 22, the bracket 30 may further include a second mounting member 330 for locking the case 20 to 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 FIG. 22, the second mounting member 330 may include a locking mechanism and passageway that can cooperate with the first mounting member 230 on the case 20 (e.g., the locking portion shown in FIG. 12) to lock and unlock the case 20 to the bracket 30.
[0190] According to the technical solution of the embodiment of the present application, the second mounting member 330 for locking the case 20 is installed adjacent to the third stopper 310, and the position limiting action of the third stopper 310 improves the reliability of the locking mounting of the case 20 by the second mounting member 330, and further improves the mounting stability of the case 20 to the bracket 30.
