Description

Technical Field

[0001] This application relates to the field of battery module installation and maintenance technology, and more specifically, to a top cover assembly, a battery module and an energy storage device. Background Technology

[0002] To facilitate the handling of residential energy storage battery modules, a handling handle is usually provided on the top cover of the battery module. However, most of the current handling handles are fixed to the top cover by welding. This structure means that when the battery modules are stacked and assembled, a large clearance groove needs to be designed on the bottom plate of the corresponding battery module, which in turn affects the installation space of the battery cells inside the battery module.

[0003] In summary, how to solve the problem that the design of the top cover of the battery module affects the installation space of the battery cells inside the battery module due to the design of the handling handle has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, this application provides a top cover assembly, a battery module, and an energy storage device to solve the problem that the design of the top cover of the battery module affects the installation space of the battery cells inside the battery module due to the design of a handling handle.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A top cover assembly, comprising:

[0007] Top cover body, used to be mounted on top of the battery module;

[0008] A limiting member is disposed on the top cover body, and a first limiting part is formed on the side of the top cover body facing away from the battery module;

[0009] The carrying handle is provided with a second limiting part, which is configured to engage with the first limiting part, so as to enable the carrying handle to perform the carrying function by restricting the movement of the carrying handle relative to the top cover body in a first direction;

[0010] Wherein, the first direction is the direction perpendicular to the top cover body.

[0011] In some embodiments of this application, the top cover assembly further includes a bottom support member disposed on the side of the top cover body facing the battery module. The top cover body has a through hole. A first end of the limiting member passes through the through hole and is connected to the bottom support member. A second end of the limiting member is used to form a first limiting portion on the side of the top cover body facing away from the battery module.

[0012] In some embodiments of this application, the bottom support member and the top cover body are separate structures and are not connected to each other. The limiting member and the through hole slide in the first direction and can switch back and forth between the first sliding position and the second sliding position.

[0013] When the limiting member is in the first sliding position, the bottom support member abuts against the side of the top cover body facing the battery module, and the second end of the limiting member forms the first limiting part on the side of the top cover body facing away from the battery module;

[0014] When the limiting member is in the second sliding position, the bottom support member is disengaged from the side of the top cover body facing the battery module, and the second end of the limiting member is attached to the side of the top cover body facing away from the battery module.

[0015] In some embodiments of this application, the base support member is fixed to the top cover body.

[0016] In some embodiments of this application, the limiting member is configured as a threaded fastener, the shank of which is threadedly connected to the base support member. The first limiting portion is an anti-detachment stop formed by the head of the threaded fastener on the side of the top cover body facing away from the battery module. The second limiting portion is a slot formed at the bottom of the handling handle, which can engage with the anti-detachment stop to restrict the handling handle from moving relative to the top cover body in the first direction.

[0017] In some embodiments of this application, the slot includes a sliding groove and a limiting countersink disposed at the sliding end of the sliding groove. The sliding groove is used for the shank of the threaded fastener to slide into, and the limiting countersink is used to fit with the head of the threaded fastener.

[0018] In some embodiments of this application, the first limiting portion is configured as a slot, and the second limiting portion is configured as a tongue that is adapted to the slot.

[0019] In some embodiments of this application, the number of limiting members is two sets, and they are arranged opposite to each other in a second direction, wherein the second direction is the length direction of the top cover body.

[0020] In some embodiments of this application, the carrying handle is further provided with a first fixing part and a second fixing part. The first fixing part is configured to be detachably fixed to the wall, and the second fixing part is used to connect with the top cover body so that the carrying handle can achieve a fixing function.

[0021] In some embodiments of this application, the top cover assembly further includes a connecting member configured to connect the top cover body to the second fixing portion.

[0022] In some embodiments of this application, the connecting member and the top cover body are configured as an integral structure or a separate fixed connection structure.

[0023] In some embodiments of this application, the connecting member and the second fixing part are constructed as an integral structure;

[0024] Alternatively, the connecting member and the second fixing part may be configured as a separate fixed connection structure;

[0025] In some embodiments of this application, the connecting member and the second fixing part are configured as a separate movable connection structure.

[0026] In some embodiments of this application, the second fixing part is a limiting notch disposed at the bottom of the carrying handle and arranged facing the wall, and the connecting member is provided with a limiting stop that engages with the limiting notch.

[0027] To address the issue that the design of a carrying handle on the top cover of a battery module affects the installation space of the battery cells inside the battery module, this application provides a top cover assembly, including a top cover body, a limiting member, and a carrying handle. The top cover body is disposed on the top of the battery module; the limiting member is disposed on the top cover body, and a first limiting portion is formed on the side of the top cover body facing away from the battery module; the carrying handle is provided with a second limiting portion, which is configured to engage with the first limiting portion, so as to restrict the movement of the carrying handle relative to the top cover body along a first direction, thereby enabling the carrying handle to perform a carrying function; the first direction is a direction perpendicular to the top cover body.

[0028] In practical applications, the top cover assembly is installed on top of the battery module. When the battery module needs to be moved, the second limiting part of the moving handle can be engaged with the first limiting part, thereby restricting the movement of the moving handle relative to the top cover body along a first direction, which is perpendicular to the top cover body. The battery module can then be moved by lifting the moving handle upwards, thus enabling the moving operation of the battery module. After the battery module has been moved to the designated position, the moving handle can be removed, disengaging the second limiting part from the first limiting part. The moving handle can then continue to move other battery modules. Each handling handle allows for the individual lifting and moving of multiple battery modules, significantly improving the utilization rate of the handling handles, reducing the number of handling handles required, and helping to reduce costs. In addition, when battery modules do not need to be moved, such as when battery modules are stacked, since the handling handles on the top cover of the battery module have been removed, there is no need to consider avoiding the handling handles on the bottom plate of the battery module. This avoids the problem of the handling handles on the top cover of the battery module affecting the installation space of the battery cells inside the battery module. Moreover, compared with the traditional top cover structure of battery modules, it can effectively reduce the overall volume of the battery module for the same capacity.

[0029] On the other hand, this application also provides a battery module, including a top cover assembly, which is the top cover assembly described in any of the above solutions. Since the aforementioned top cover assembly has the above-mentioned technical effects, the battery module having this top cover assembly should also have the corresponding technical effects, which will not be elaborated further here.

[0030] Furthermore, this application also provides an energy storage device, including a battery module and a switch box module disposed above the battery module, wherein the battery module is the battery module described in the above solution. Since the battery module has the aforementioned technical effects, the energy storage device having this battery module should also have corresponding technical effects, which will not be elaborated further here.

[0031] The technical features mentioned above, those to be mentioned below, and those shown individually in the accompanying drawings can be combined arbitrarily, provided that the combined technical features are not contradictory. All feasible combinations of features are the technical content explicitly described herein. Any one of the multiple sub-features contained in the same statement can be applied independently, without necessarily being applied together with other sub-features. Attached Figure Description

[0068] The core of this application is to provide a top cover assembly, a battery module, and an energy storage device to solve the problem that the design of the top cover of the battery module affects the installation space of the battery cells inside the battery module due to the design of a handling handle.

[0069] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0070] In existing technologies, with the continuous maturation of energy storage devices, residential energy storage battery modules are gradually becoming more widespread. To facilitate the handling of residential energy storage battery modules, a handling handle is usually provided on the top cover of the battery module. This handling handle is mainly used to facilitate users in moving the battery module. However, most of the current handling handles are fixed to the top cover by welding. This structural form requires that when stacking and assembling battery modules, a large clearance groove needs to be designed on the bottom plate of the corresponding battery module so that the upper battery module can be smoothly stacked on top of the lower battery module. However, it is precisely because of the concave design of the clearance groove that the internal space of the battery module is occupied, which in turn affects the installation space of the battery cells inside the battery module.

[0071] Based on this, one aspect of the present application provides a top cover assembly applied to a battery module to solve the problem that the top cover of the battery module affects the installation space of the battery cells inside the battery module due to the design of a handling handle.

[0072] Specifically, refer to Figure 1As shown, the top cover assembly 1 specifically includes a top cover body 11, a limiting member 12, and a handling handle 13. The top cover body 11 is mounted on top of the battery module 2 and is generally fixed to the top of the battery module 2 by fasteners. It needs to meet certain strength requirements and can be made of, but is not limited to, iron. The top cover body 11 can be designed with reinforcing structures, such as stamped reinforcing ribs, to enhance its resistance to deformation. The limiting member 12 is disposed on the top cover body 11. Its specific arrangement can be either fixed to the top cover body 11 or it can pass through the top cover body 11 and connect to related components on the side of the top cover body 11 facing the battery module. This will be specifically described in the following embodiments. A first limiting portion 121 is formed on the side of the top cover body 11 facing away from the battery module 2; a second limiting portion 131 is provided on the handling handle 13, which is configured to engage with the first limiting portion 121 to restrict the movement of the handling handle 13 relative to the top cover body 11 in a first direction, thereby enabling the handling handle 13 to perform a handling function. That is, the handling handle 13 has a first usage mode. In the first usage mode, the second limiting portion 131 of the handling handle 13 engages with the first limiting portion 121 to restrict the movement of the handling handle 13 relative to the top cover body 11 in the first direction, thereby enabling the handling handle 13 to perform a handling function. The first direction is specifically the direction perpendicular to the top cover body 11 as shown in Figure 1.

[0073] In practical applications, the top cover assembly 1 is installed on top of the battery module 2. When the battery module 2 needs to be moved, the handling handle 13 can be used in the first usage mode. At this time, the second limiting part 131 of the handling handle 13 engages with the first limiting part 121, thereby restricting the movement of the handling handle 13 relative to the top cover body 11 in the first direction, which is perpendicular to the top cover body. Then, the battery module 2 can be moved by lifting the handling handle 13 upwards, thus realizing the moving operation of the battery module 2. After the battery module 2 is moved to the designated position, the handling handle 13 can be removed, that is, the second limiting part 131 disengages from the first limiting part 121, and the handling handle 13 can then continue to move. For transporting other battery modules 2, multiple battery modules 2 can be lifted one by one using a single transport handle 13, which greatly improves the utilization rate of the transport handle 13, saves on the number of transport handles 13, and helps reduce costs. In addition, when it is not necessary to transport battery modules 2, such as when battery modules 2 are stacked, since the transport handle 13 on the top cover body 11 of battery module 2 has been removed, there is no need to consider avoiding the transport handle 13 on the bottom plate of battery module 2. This avoids the problem of affecting the installation space of battery units inside battery module 2 due to the design of transport handle 13 on the top cover of battery module 2. Moreover, compared with the traditional top cover structure of battery module 2, the overall volume of battery module 2 can be effectively reduced for the same capacity.

[0074] It is worth mentioning that, in order to make the operation of the second limiting part 131 engaging with the first limiting part 121 and the operation of the second limiting part 131 disengaging from the first limiting part 121 smoother, the mutual engagement of the two is generally designed with a certain amount of play. Specifically, refer to... Figure 2 As shown, the Figure 2 This illustration shows the situation where, in the first usage mode, the second limiting part 131 of the handling handle 13 is engaged with the first limiting part 121 but has not yet been lifted in the first direction. At this time, the handling handle 13 is lifted until the second limiting part 131 has no room for movement relative to the first limiting part 121 in the first direction, that is... Figure 3 As shown, if the handling handle 13 is lifted further, the battery module 2 can be lifted and moved.

[0075] In some specific implementation plans, refer to Figure 1 Combination Figure 4 As shown, the top cover assembly 1 may further include a bottom support member 14. The bottom support member 14 is disposed on the side of the top cover body 11 facing the battery module 2. Specifically, it can be directly fixed to the top cover body 11, or it can be independent and not fixed. The top cover body 11 is provided with a through hole 111. The first end of the limiting member 12 passes through the through hole 111 and is connected to the bottom support member 14. The second end of the limiting member 12 is used to form a first limiting part 121 on the side of the top cover body 11 facing away from the battery module 2. That is, the first end of the limiting member 12 is located on the bottom side of the top cover body 11 and connected to the bottom support member 14, and the second end is located on the top side of the top cover body 11 and forms the first limiting part 121. By designing the base support component 14 and connecting the first end of the limiting component 12 to the base support component 14, when the handling handle 13 is lifted upward, the upward force generated by the limiting component 12 is transmitted to the top cover body 11 through the base support component 14. The force can be dispersed through the base support component 14, which alleviates the local force acting on the top cover body 11 and reduces the risk of deformation of the top cover body 11.

[0076] In a further implementation plan, refer to Figure 4 and Figure 8As shown, the bottom support member 14 and the top cover body 11 can be designed as separate structures and are not connected. The limiting member 12 and the through hole 111 slide in the first direction and can switch back and forth between the first sliding position and the second sliding position. When the limiting member 12 is in the first sliding position, the bottom support member 14 and the side of the top cover body 11 facing the battery module 2 (i.e., the bottom surface of the top cover body 11) abut against each other. The second end of the limiting member 12 forms a first limiting part 121 on the side of the top cover body 11 facing away from the battery module 2 (i.e., the top surface of the top cover body 11). When the limiting member 12 is in the second sliding position, the bottom support member 14 and the side of the top cover body 11 facing the battery module 2 (i.e., the bottom surface of the top cover body 11) separate, and the second end of the limiting member is attached to the side of the top cover body 11 facing away from the battery module 2 (i.e., the top surface of the top cover body 11).

[0077] Specifically, refer to Figure 4 ,Should Figure 4 The illustration shows the limiting member 12 in the first sliding position. At this time, the second end of the limiting member 12 forms a first limiting part 121 on the side of the top cover body 11 facing away from the battery module 2 (i.e., the top surface of the top cover body 11). The second limiting part 131 on the handling handle 13 can be engaged with the first limiting part 121, thereby realizing the lifting function of the handling handle 13. When lifting is not required, the second end of the limiting member 12 can be pressed to slide it from the first sliding position to the second sliding position. At that time, the second end of the limiting member is in contact with the side of the top cover body 11 facing away from the battery module 2 (i.e., the top surface of the top cover body 11), so that the limiting member 12 does not protrude too much on the top surface of the top cover body 11, further reducing the clearance space design on the bottom plate of the battery module 2. Although no relevant diagram is given for this situation, it does not affect the understanding of those skilled in the art.

[0078] It is understandable that the aforementioned base support component 14 can also be directly fixed to the bottom surface of the top cover body 11, or the base support component 14 and the top cover body 11 can be designed as an integral structure. In actual application, the arrangement can be selected according to actual needs, and no more specific limitations are made here.

[0079] For example, refer to Figure 4The aforementioned limiting member 12 can be specifically constructed as a threaded fastener, such as a bolt or screw, with the shank of the threaded fastener threadedly connected to the base support member 14. In this case, the first limiting part 121 is an anti-detachment stop formed by the head of the threaded fastener on the side of the top cover body 11 facing away from the battery module 2. The second limiting part 131 can specifically be a slot formed at the bottom of the handling handle 13, which can engage with the anti-detachment stop to restrict the movement of the handling handle 13 relative to the top cover body 11 in the first direction. By designing this structural form, the connection and disassembly between the limiting member 12 and the base support member 14 are more convenient, and it is easier to maintain and replace them later.

[0080] For example, refer to Figure 5 As shown, the aforementioned slot may specifically include a sliding groove 1311 and a limiting recess 1312 disposed at the sliding end of the sliding groove 1311, wherein, referring to Figure 6 The sliding groove 1311 is used for the shank of the threaded fastener (referring to the part located on the top surface of the top cover body 11) to slide into, see reference. Figure 7 The limiting groove 1312 is used to fit with the head of the threaded fastener. Specifically, when the handling handle 13 is lifted upward, the limiting groove 1312 engages with the head of the threaded fastener, thereby preventing the second limiting part 131 from falling off from the first limiting part 121 during the lifting and handling process of the handling handle 13, which helps to improve safety performance.

[0081] It is understandable that designing the first limiting part 121 and the second limiting part 131 into the above-described structural form is merely an example of the embodiments of this application. In actual application, other limiting and engaging structures can also be designed, such as the first limiting part 121 being constructed as a slot and the second limiting part 131 being constructed as a tongue that is adapted to the slot. After the tongue and the slot are engaged, they can restrict the movement of the two along the first direction.

[0082] In some more specific implementation plans, refer to Figure 1 Combination Figure 12 The aforementioned limiting components 12 can be designed in two sets, arranged opposite each other in the second direction, which is the length direction of the top cover body 11. By designing this structure, the battery module 2 can be lifted by two handling handles 13, which are arranged opposite each other in the length direction of the top cover body 11, making the lifting effect more stable and reliable, and convenient for users to apply force.

[0083] In some other specific implementation schemes, refer to Figure 12 and Figure 13 , combined Figure 10 and Figure 11The carrying handle 13 may be provided with a first fixing part 132 and a second fixing part 133. The first fixing part 132 is configured to be detachably fixed to the wall 4. That is, the carrying handle 13 may also have a second usage mode. In the second usage mode, the first fixing part 132 is detachably fixed to the wall 4. For example, the first fixing part 132 is a fixing hole designed on the carrying handle 13, which is fixed to the wall 4 by fasteners. Or, the first fixing part 132 is a first snap-fit ​​part designed on the carrying handle 13, and the wall 4 is designed with a second snap-fit ​​part. The first snap-fit ​​part and the second snap-fit ​​part are locked together. The specific structural form and fixing method are not limited here and can be selected according to actual needs. The second fixing part 133 is used to connect to the top cover body 11 in the second usage mode. Specifically, it can be a direct connection, an indirect connection, or a movable connection with a limiting effect. It is not limited here. By designing the handling handle 13 into the above-described structure, the handling handle 13 not only has a handling function in the first usage mode, but also can fix the battery module 2 to prevent tipping in the second usage mode, eliminating some of the fixing parts of the battery module 2 and helping to save costs.

[0084] It is worth mentioning that after the battery module 2 is stacked and assembled in a designated area, it usually needs to be secured to a certain extent to prevent it from tipping over. The traditional method is to secure it by designing additional fixing components, while the handling handle 13 provided in this application can replace some of the fixing components in the second usage mode.

[0085] In some specific implementation plans, refer to Figure 12 and Figure 13 The aforementioned top cover assembly 1 may further include a connecting member 15, which is configured to connect the top cover body 11 and the second fixing part 133. Specifically, in the second usage mode, the connecting member 15 connects the top cover body 11 and the second fixing part 133. By designing this connecting member 15, the connection between the second fixing part 133 and the top cover body 11 becomes more convenient.

[0086] For example, the connecting member 15 and the top cover body 11 can be constructed as an integral structure. This embodiment does not provide relevant drawings, but this does not affect the understanding of the solution by those skilled in the art. In this case, the connection operation between the connecting member 15 and the top cover body 11 can be omitted.

[0087] For example, refer to Figure 12 and Figure 13 As shown, the connecting member 15 and the top cover body 11 can be constructed as a separate fixed connection structure, specifically, but not limited to, using fasteners for fixation. By designing it into this structural form, the connecting member 15 can be removed at any time as needed.

[0088] For example, the connecting member 15 and the second fixing part 133 can be constructed as an integral structure. This embodiment does not provide relevant drawings, but it does not affect the understanding of the solution itself by those skilled in the art. By designing it into this structural form, the connection operation between the connecting member 15 and the second fixing part 133 can be eliminated.

[0089] For example, refer to Figure 9 The connecting member 15 and the second fixing part 133 can also be constructed as a separate fixed connection structure, such as, but not limited to, using fasteners for connection.

[0090] For example, refer to Figure 10 and Figure 11 The connecting member 15 and the second fixing part 133 are configured as a separate movable connection structure. For example, the second fixing part 133 can be a limiting notch 133' located at the bottom of the handling handle 13 and facing the wall 4, and the connecting member 15 is provided with a limiting stop 151 that engages with the limiting notch 133'. By engaging the two, the limiting notch 133' can limit the battery module 2 through the connecting member 15, thus preventing it from being touched and tipped over.

[0091] On the other hand, this application also provides a battery module, including a top cover assembly 1, which is the top cover assembly 1 described in any of the above-mentioned solutions. Since the aforementioned top cover assembly 1 has the above-mentioned technical effects, the battery module 2 having the top cover assembly 1 should also have the corresponding technical effects, which will not be repeated here.

[0092] Furthermore, embodiments of this application also provide an energy storage device, referring to... Figure 14 and Figure 15 The energy storage device includes a battery module 2 and a switch box module 3 disposed above the battery module 2, wherein the battery module 2 is the battery module 2 described in the above scheme. Since the battery module 2 has the above-mentioned technical effects, the energy storage device having the battery module 2 should also have the corresponding technical effects, which will not be elaborated here.

[0093] It is worth mentioning that, referring to Figure 16 As shown, when the handle 13 is used in the second mode, the switch box module 3 can provide a certain degree of shielding effect. At this time, the handle 13 is hidden in the assembly gap between the switch box module and the wall, which serves to store the handle 13.
