Description

Technical Field

[0001] The present disclosure relates to the technical field of battery packs, and in particular to battery packs and vehicles. Background Art

[0002] A battery pack includes a housing and electrical components mounted within it. In related art, a horizontal partition is typically installed within the housing to separate the interior space of the housing into an upper layer and a lower layer, where the upper layer is the electrical compartment and the lower layer is the energy compartment. The partition has mounting holes for power connectors, which are used to electrically connect the electrical compartment and the energy compartment. The energy compartment contains a large number of battery cells, which are susceptible to mechanical impact during use or transportation, causing the housing to deform. This can lead to the risk of loosening or falling cells in the energy compartment. Furthermore, the cells can easily short-circuit with the housing, posing a safety hazard. Utility Model Content

[0007] an adapter, which passes through the mounting hole and has a mounting gap with a hole wall of the mounting hole; and

[0008] The sealing portion is used to seal the installation gap so as to isolate the first space and the second space from each other.

[0010] Optionally, the sealing component includes a sleeve arranged in the mounting hole, an annular groove for the hole wall to extend into is formed on the outer peripheral surface of the sleeve, and the sleeve elastically presses between the hole wall and the side wall of the adapter.

[0011] Optionally, a first chamfer is formed at the lower edge of the inner ring of the sheath.

[0012] Optionally, the sealing component includes a sealing ring sleeved on the side wall of the adapter, and the sealing ring elastically presses between the hole wall and the side wall of the adapter.

[0013] Optionally, a second chamfer is formed at the upper edge of the outer ring of the sealing ring.

[0014] Optionally, the adapter includes:

[0015] a main body, passing through the mounting hole; and

[0016] A flange is provided on the outer periphery of the main body, the flange is parallel to the partition plate and is fixedly connected to the partition plate via a fastener, and the bottom surface of the sealing member abuts against the top surface of the flange.

[0017] Optionally, the adapter includes:

[0018] a main body, passing through the mounting hole; and

[0019] A flange is provided on the outer periphery of the main body, the flange is parallel to the partition plate and is fixedly connected to the partition plate by fasteners,

[0020] The sealing member comprises a sealing gasket sleeved on the main body, and the sealing gasket elastically presses between the bottom surface of the partition plate and the top surface of the flange.

[0021] Optionally, an annular positioning groove is formed on the top surface of the flange, and the sealing gasket is arranged in the positioning groove.

[0022] Optionally, the diameter of the inner ring of the sealing gasket is equal to the diameter of the outer circumference of the main body.

[0023] Optionally, it also includes:

[0024] a first electrical connector disposed in the first space and electrically connected to the adapter and the first electrical component in the first space; and

[0025] The second electrical connector is disposed in the second space and electrically connected to the adapter and the second electrical component in the second space.

[0026] The technical solutions provided by the embodiments of the present disclosure may include the following beneficial effects: By pouring filler glue into the first space, the connection stability between electrical components (e.g., battery cells) and the housing within the first space is improved, as well as the first space's resistance to external forces and deformation. The filler glue also insulates the electrical components from the housing, preventing short circuits and other issues. During actual battery pack assembly, the divider plate is installed after the first space is filled with glue, while the adapter is installed before. Therefore, after the first space is filled with glue, the portion of the adapter located within the first space is secured by the filler glue, effectively fixing the position of the adapter. During separator plate installation, since the adapter and mounting hole are fixed in position, any positional error between the mounting hole and the adapter (e.g., due to uncontrollable foaming factors, process accuracy, etc.) can lead to misalignment between the two. However, a mounting clearance between the mounting hole wall and the adapter can mitigate this issue. The mounting clearance is defined as the inner contour of the mounting hole being larger than the outer contour of the adapter. This allows the adapter to fit into the mounting hole within a certain range of positional error, completing the separator plate installation. Furthermore, the installation gap can be sealed by providing a sealing portion, thereby preventing the filling glue in the first space from overflowing into the second space.

[0027] It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0036] Reference Figures 1-4 The present disclosure exemplifies a battery pack, comprising a shell 1, a partition plate 2 disposed within the shell 1, an adapter 3, and a sealing portion. The partition plate 2 divides the interior of the shell 1 into a first space 101 and a second space 102. The partition plate 2 has a mounting hole 21 connecting the first space 101 and the second space 102. The first space 101 is located on the lower side of the partition plate 2 and is filled with a filling glue 6. The partition plate 2 serves as the upper cover of the first space 101 and also serves as the bottom plate of the second space 102. During the assembly process, the partition plate 2 is installed after the filling glue 6 is poured into the first space 101. The mounting hole 21 can be formed integrally with the partition plate 2, or it can be processed later by a lathe or the like. The adapter 3 is inserted through the mounting hole 21 and has an installation gap with the hole wall of the mounting hole 21, that is, the inner contour of the mounting hole 21 is larger than the outer contour of the adapter 3, so that the installation gap exists when the adapter 3 is inserted through the mounting hole 21. The sealing portion is used to seal the installation gap so that the first space 101 and the second space 102 are isolated from each other. The present disclosure does not limit the specific structure of the sealing part, as long as it can achieve a sealing effect. The specific structure can be found below.

[0037] In the embodiments of the present disclosure, the size of the installation gap can be greater than or equal to 4mm, thereby ensuring that the adapter 3 and the mounting hole 21 are within the allowable position error range, the adapter 3 can be smoothly installed in the mounting hole 21, and it can be ensured that the sheath 41, sealing ring 42, etc. mentioned below can be installed in the installation gap to form a seal. In this case, the size difference between the mounting hole 21 and the corresponding position of the adapter 3 needs to be greater than or equal to 8mm, 10mm, etc., to ensure that the installation gap can be greater than or equal to 4mm within the allowable position error range. In addition, in some other embodiments, the installation gap can also be greater than or equal to 6mm, etc., and the specific design can be adaptive according to actual conditions.

[0038] The “pouring” mentioned in the present disclosure refers to filling all or almost filling the gaps in the first space 101 with the filling glue 6 to ensure the connection stability and insulation between the various components, as well as to improve the impact resistance and deformation resistance of the space, thereby protecting the internal components. The present disclosure does not limit the type of the filling glue 6. For example, in some embodiments, the filling glue 6 may be a foaming glue. Foaming glue refers to a glue with foaming and bonding properties, which is mainly used for filling, sealing, bonding, etc. It is a polyurethane elastic sealing foam material that relies on moisture curing. Alternatively, in some other embodiments, the filling glue 6 may also be a non-foaming glue, as long as it can fill the gap in the first space 101.

[0039] Adapter 3 is an electrical connector that extends from one end of mounting hole 21 to the other, with one end located in first space 101 and the other in second space 102. This allows each end to connect to the electrical components within the corresponding spaces, thereby establishing an electrical connection between the electrical components in first space 101 and second space 102. The ends of adapter 3 can be designed to adapt to the structure of the electrical components to be connected, and can specifically include pluggable terminals, copper plates, etc.

[0040] By using the above-described technical solution, by pouring filler 6 into first space 101, the connection stability between electrical components (e.g., battery cells) and the housing 1 within first space 101 can be improved, as can the first space 101's resistance to external forces and deformation. The filler 6 also insulates the electrical components from the housing 1, preventing problems such as short circuits. During actual assembly of the battery pack, the partition plate 2 needs to be installed after the first space 101 is filled with glue, while the adapter 3 is installed before. Therefore, after the first space 101 is filled with glue, the portion of the adapter 3 located within the first space 101 is secured by the filler 6, effectively fixing the position of the adapter 3. When installing the partition plate 2, since the adapter 3 and the mounting hole 21 are fixed in position, any positional error between the mounting hole 21 and the adapter 3 (e.g., due to uncontrollable foaming factors, process accuracy, etc.) can prevent the two from being aligned. However, a mounting gap between the hole wall of the mounting hole 21 and the adapter 3 can avoid this problem. The mounting gap is defined as the inner contour of the mounting hole 21 being larger than the outer contour of the adapter 3. This allows the adapter 3 to extend into the mounting hole 21 within a certain range of positional error, completing the installation of the partition plate 2. Furthermore, the sealing portion can be provided to seal the mounting gap, preventing the filler 6 in the first space 101 from overflowing into the second space 102.

[0041] Reference Figure 2-Figure 4 In an embodiment of the present disclosure, the sealing portion may include a sealing member 4 surrounding the adapter 3, and the sealing member 4 may be elastically pressed between the adapter 3 and the partition plate 2. By elastically pressing the sealing member 4 between the adapter 3 and the partition plate 2, the sealing member 4 always has an elastic restoring force, thereby pressing the adapter 3 and the partition plate 2 tightly, thereby improving the sealing effect.

[0042] The present disclosure does not limit the specific structure of the sealing member 4. Several embodiments will be described below with reference to the accompanying drawings. Specifically:

[0043] First embodiment:

[0044] Reference Figure 2In this embodiment, the sealing member 4 can include a sleeve 41 arranged in the mounting hole 21, and an annular groove 411 can be formed on the outer circumferential surface of the sleeve 41 for the hole wall to extend into. The sleeve 41 can be elastically abutted between the hole wall and the side wall of the adapter 3. In assembly, the sleeve 41 is arranged in the mounting hole 21 through the annular groove 411, and at this time, the hole wall extends into the annular groove 411. Then, the partition plate 2 is arranged so that the adapter 3 passes through the sleeve 41, so that the sleeve 41 is elastically abutted between the hole wall and the side wall of the adapter 3, forming the above-mentioned sealing effect, avoiding the filling glue 6 in the first space 101 from overflowing into the second space 102. In addition, the sealing member 4 is arranged as an elastic member, which can absorb the installation error between the adapter 3 and the mounting hole 21 when the adapter 3 extends into the mounting hole 21. That is, when there is a certain misalignment between the axial centers of the adapter 3 and the mounting hole 21, the elastic member can provide different compression deformation amounts at different positions to absorb the misalignment size, so that the adapter 3 can be smoothly arranged into the mounting hole 21 and form a sealing effect.

[0045] Referring to Figure 2 In this embodiment, the lower edge position of the inner ring of the sleeve 41 can form a first chamfered bevel 412. The first chamfered bevel 412 can be used as a guide during assembly. Specifically, when the adapter 3 is moved from the lower side of the partition plate 2 to the upper side, the chamfered bevel arrangement can provide a larger extension space for the adapter 3, and through the guiding effect of the chamfered bevel, it is easier to enter the sleeve 41 and pass through and extend into the second space 102.

[0046] Referring to Figure 2 In this embodiment, the adapter 3 can include a main body 31 arranged in the mounting hole 21, and a flange 32 arranged on the outer circumference of the main body 31. The flange 32 can be parallel to the partition plate 2 and fixedly connected to the partition plate 2 through the fastener 5, and the bottom surface of the sleeve 41 can abut against the top surface of the flange 32. In this way, when the adapter 3 moves from the lower side of the partition plate 2 to the upper side, when the flange 32 abuts against the bottom surface of the sleeve 41, it is installed in place, and at this time, it can be locked by locking the fastener 5.

[0047] Second embodiment:

[0048] Referring to Figure 3In the embodiment, the sealing member 4 can include a sealing ring 42 sleeved on the side wall of the adapter 3, and the sealing ring 42 can be elastically abutted between the hole wall and the side wall of the adapter 3. During installation, the sealing ring 42 is first sleeved on the side wall of the adapter 3, and the adapter 3 is moved from one side of the mounting hole 21 to the other side until the sealing ring 42 is elastically abutted between the hole wall and the side wall of the adapter 3, thereby achieving the sealing effect described above and preventing the filling glue 6 in the first space 101 from overflowing into the second space 102. In addition, the sealing member 4 is provided as an elastic member, which can absorb the installation error between the adapter 3 and the mounting hole 21 when the adapter 3 is inserted into the mounting hole 21. That is, when there is a certain misalignment between the shaft centers of the adapter 3 and the mounting hole 21, different compression deformation amounts can be provided at different positions of the elastic member to absorb the misalignment size, so that the adapter 3 can be smoothly installed into the mounting hole 21 and the sealing effect can be achieved.

[0049] With reference to Figure 3 In the embodiment, the upper edge position of the outer ring of the sealing ring 42 is formed with a second chamfered bevel 421. The second chamfered bevel 421 can be used as a guide during installation. Specifically, when the adapter 3 drives the sealing ring 42 to move upward, the outer contour of the top end position of the chamfered bevel 421 of the sealing ring 42 is smaller, which makes it easier to extend into the mounting hole 21, and the sealing ring 42 is further extended into the mounting hole 21 through the chamfered bevel, thereby achieving the sealing effect.

[0050] With reference to Figure 3 In the embodiment, the adapter 3 can include a main body 31 sleeved in the mounting hole 21 and a flange 32 provided on the outer periphery of the main body 31. The flange 32 can be fixedly connected with the partition plate 2 in parallel to the partition plate 2 through the fastener 5, and the bottom surface of the sealing ring 42 can abut against the top surface of the flange 32. By positioning the bottom surface of the sealing ring 42 on the top surface of the flange 32, the top surface of the flange 32 can function as a stop during the “insertion” of the sealing ring 31 into the mounting hole 21, thereby preventing the sealing ring 42 from sliding downward under force during installation.

[0051] In the first and second embodiments, the bottom surface of the sealing member 4 abuts against the top surface of the flange 32 to function as a stop, while the function of the flange 32 in the third embodiment is to seal the surface, specifically:

[0052] Third embodiment:

[0053] With reference to Figure 4In this embodiment, the adapter 3 may include: a main body 31, which is inserted into the mounting hole 21; and a flange 32, which is disposed on the outer periphery of the main body 31. The flange 32 may be parallel to the partition plate 2 and fixedly connected to the partition plate 2 via a fastener 5. The sealing member 4 may include a sealing gasket 43, which is sleeved on the main body 31 and can elastically abut between the bottom surface of the partition plate 2 and the top surface of the flange 32. By providing the elastically abutting sealing gasket 43 between the bottom surface of the partition plate 2 and the top surface of the flange 32, the installation gap between the hole wall and the adapter 3 can be sealed, thereby preventing the filling glue 6 in the first space 101 from overflowing into the second space 102.

[0054] Reference Figure 4 In this embodiment, the top surface of the flange 32 may be formed with an annular positioning groove 321, and the sealing gasket 43 may be disposed in the positioning groove 321. The positioning groove 321 may be provided to position the sealing gasket 43 in the radial direction to prevent the sealing gasket 43 from moving during operation.

[0055] The present disclosure does not impose any restrictions on the positional relationship between the sealing gasket 43 and the main body 31. For example, in some embodiments, the diameter of the inner ring of the sealing gasket 43 can be equal to the diameter of the outer circumference of the main body 31. That is, the sealing gasket 43 fits neatly on the main body 31, thereby limiting radial movement of the sealing gasket 43. In addition, in other embodiments, the diameter of the inner ring of the sealing gasket 43 can also be greater than the diameter of the outer circumference of the main body 31.

[0056] In order to make the electrical components in the first space 101 and the second space 102 electrically connected, refer to Figure 1 In an embodiment of the present disclosure, the battery pack may further include: a first electrical connector 71, disposed in the first space 101 and electrically connected to the adapter 3 and a first electrical component (not shown in the figure) in the first space 101; and a second electrical connector 72, disposed in the second space 102 and electrically connected to the adapter 3 and a second electrical component (not shown in the figure) in the second space 102. Here, the first electrical connector 71 and the second electrical connector 72 may be copper busbars or wiring harnesses, etc. When the first electrical connector 71 is a copper busbar, in addition to performing the same conductive function as the second electrical connector 72, the first electrical connector 71 may also support the adapter 3 before glue is poured, so that the adapter 3 is supported during the glue pouring process.

[0057] According to a second aspect of the present disclosure, a vehicle is provided, comprising the above-mentioned battery pack. Since the vehicle has all the beneficial effects of the above-mentioned battery pack, they are not described in detail here.

[0058] In the foregoing detailed description, reference is made to the accompanying drawings, which illustrate, by way of illustration, specific aspects of the present disclosure in which it may be practiced. In this regard, terms indicating directions or expressing positional relationships, such as "center," "longitudinal," "lateral," "length," "width," "thickness," "up," "down," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inside," "outside," "clockwise," "counterclockwise," "axial," "radial," "circumferential," etc., may be used with reference to the orientation of the figures being described. Since the components of the described devices may be positioned in a plurality of different orientations, the directional terms may be used for illustrative purposes rather than restrictive. It should be understood that other aspects may be utilized and structural or logical changes may be made without departing from the concepts of the present disclosure. Therefore, the following detailed description should not be taken in a limiting sense.

[0059] It should be understood that, unless otherwise specifically noted, the features of the various embodiments of the present disclosure described herein may be combined with each other. As used herein, the term "and / or" includes any one of the relevant listed items and any combination of any two or more thereof; similarly, "at least one of" includes any one of the relevant listed items and any combination of any two or more thereof.

[0060] It should be understood that, unless otherwise expressly specified or limited, the terms "join," "attach," "install," "connect," "connect," "fix," etc. used in the embodiments of the present disclosure should be understood in a broad sense. For example, they can be fixedly connected, detachably connected, or integrated; they can be mechanically connected, electrically connected, or communicable with each other; they can be directly connected, or indirectly connected through an intermediate medium, and they can be internally connected between two elements or an interactive relationship between two elements, unless otherwise expressly limited. For those skilled in the art, the specific meanings of the above terms in this article can be understood according to specific circumstances.

[0061] Additionally, the term "over" as used in reference to a component, element, or material layer being formed "over" or located "over" a surface may be used herein to mean that the component, element, or material layer is "indirectly" positioned (e.g., placed, formed, deposited, etc.) on the surface such that one or more additional components, elements, or layers are disposed between the surface and the component, element, or material layer. However, the term "over" as used in reference to a component, element, or material layer being formed "over" or located "over" a surface may alternatively have a specific meaning: the component, element, or material layer is "directly" positioned (e.g., placed, formed, deposited, etc.) on the surface, e.g., in direct contact with the surface.

[0062] Although terms such as "first", "second" and "third" may be used herein to describe various components, parts, regions, layers or sections, these components, parts, regions, layers or sections are not limited to these terms. On the contrary, these terms are only used to distinguish one component, part, region, layer or section from another component, part, region, layer or section. Therefore, without departing from the teachings of each example, the first component, part, region, layer or section mentioned in the examples described herein may also be referred to as the second component, part, region, layer or section. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" can explicitly or implicitly include at least one such feature. In the description herein, the meaning of "multiple" is at least two, for example, two, three, etc., unless otherwise clearly and specifically defined.

[0063] It should be understood that spatially relative terms, such as "above," "upper," "below," and "lower," are used herein to describe the relationship of one element to another element shown in the figures. Such spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, an element described as being "above" or "upper" relative to another element would then be "below" or "lower" relative to the other element. Thus, the term "above" encompasses both above and below orientations, depending on the spatial orientation of the device. The device may be oriented in other ways (e.g., rotated 90 degrees or in other orientations), and the spatially relative terms used herein should be interpreted accordingly.

[0064] Furthermore, the word "exemplary" is used herein to mean serving as an example, instance, or illustration. Any aspect or design described herein as "exemplary" is not necessarily to be construed as advantageous over other aspects or designs. Rather, the use of the word exemplary is intended to present concepts in a concrete manner. As used herein, the term "or" is intended to mean an inclusive "or" rather than an exclusive "or." That is, unless otherwise specified or clear from the context, "X applies to A or B" is intended to mean any of the natural inclusive permutations. That is, if X applies to A; X applies to B; or X applies to both A and B, then "X applies to A or B" satisfies any of the aforementioned instances. Furthermore, the articles "a" and "an," as used in this application and the appended claims, are generally understood to mean "one or more," unless otherwise specified or clear from the context to refer to the singular form.

[0065] Likewise, although the present disclosure has been shown and described with respect to one or more implementations, equivalent variations and modifications will occur to those skilled in the art upon reading and understanding this specification and the accompanying drawings. The present disclosure includes all such modifications and variations and is limited only by the scope of the claims. With particular regard to the various functions performed by the components described above (e.g., elements, resources, etc.), unless otherwise indicated, terms used to describe such components are intended to correspond to any component (functionally equivalent) that performs the specific function of the described component, even if not structurally equivalent to the disclosed structure. In addition, although particular features of the present disclosure may have been disclosed with respect to only one of several implementations, such features may be combined with one or more other features of other implementations as may be desired and advantageous for any given or particular application. Furthermore, to the extent that the terms "include," "have," "have," "have," or variations thereof are used in the detailed description or claims, such terms are intended to be inclusive in a manner similar to the term "comprising."

[0066] Those skilled in the art will readily appreciate other embodiments of the present disclosure after considering the specification and practicing the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of the present disclosure that follow the general principles of the present disclosure and include common knowledge or customary techniques in the art not disclosed herein. The description and examples are to be considered as exemplary only, with the true scope and spirit of the present disclosure being indicated by the appended claims.

[0067] It should be understood that the present disclosure is not limited to the exact structures that have been described above and shown in the drawings, and that various modifications and changes can be made without departing from the scope thereof. The scope of the present disclosure is limited only by the appended claims.
