Description

Technical Field

[0001] This application relates to the field of energy storage equipment technology, and in particular to a detachable handling handle. Background Technology

[0002] In the production, assembly, or field deployment of energy storage devices (such as battery packs), multiple energy storage units (i.e., energy storage stacking systems) are often stacked layer by layer to form an overall energy storage module. In traditional technology, each energy storage stacking system is fixedly equipped with a pair of dedicated handles, which workers use to move and stack the system. However, this traditional approach has at least the following drawbacks: (1) The handle only serves a portable function during the stacking installation process. Once the stacking is completed, the handle loses its actual function and remains idle on the energy storage stacking system for a long time without participating in the operation of subsequent equipment. In other words, the handle has a single function and low utilization rate.

[0003] (2) Each energy storage stack system needs to be equipped with a pair of handles independently. As the number of energy storage systems increases, the material cost, processing cost and installation cost of the handles increase significantly, which increases the overall production cost of the energy storage equipment.

[0004] (3) Fixed handles will occupy additional external space required by the overall energy storage module, which may affect the compactness of the overall structure after stacking, or cause inconvenience to subsequent equipment maintenance. Utility Model Content

[0005] In view of this, the purpose of this application is to provide at least one detachable handling handle. By designing a detachable snap-fit ​​component, a detachable connection between the handle and the object to be moved can be achieved. For objects of the same size, only one pair of handles is needed to complete the movement of all objects, thereby improving the utilization rate of the handle, reducing the production cost of energy storage devices, and reducing the external space occupation.

[0006] This application mainly includes the following aspects: In a first aspect, embodiments of this application provide a detachable handling handle, which includes a detachable snap-fit ​​component and a handle component. The cross-section of the detachable snap-fit ​​component is a multi-bend semi-closed shape, and the detachable snap-fit ​​component forms a detachable connection with the edge of the object to be transported through the semi-closed notch. The handle component is integrally connected with the detachable snap-fit ​​component.

[0007] In one possible implementation, the multi-bend semi-closed shape includes a main body segment, a first extension segment, and a second extension segment. One end of the main body segment is integrally connected to one end of the first extension segment to form a first bend angle. The other end of the main body segment away from the first extension segment is integrally connected to one end of the second extension segment to form a second bend angle. The first extension segment and the second extension segment are arranged opposite to each other, and an opening of the multi-bend semi-closed shape is formed between the other ends of the first extension segment and the other ends of the second extension segment.

[0008] In one possible implementation, the other end of the first extension segment away from the main body segment is bent to form a hook-shaped structure that fits the edge of the object to be transported. The detachable snap-fit ​​assembly has a first preset length in the vertical direction of its cross section, and the semi-closed notch is formed by the hook-shaped structure and the second extension segment surrounding it.

[0009] In one possible implementation, the first distance between the other end of the second extension segment away from the main body segment and the hook structure is less than the width of the edge of the object to be transported.

[0010] In one possible implementation, when the detachable snap-fit ​​assembly is installed on the edge of the object to be transported, the other end of the second extension, away from the main body, abuts against the side wall of the object to be transported, to which the edge belongs. In one possible implementation, one end of the grip assembly is integrally connected to the detachable snap-fit ​​assembly, and the other end of the grip assembly forms a handle; the grip assembly has a second preset length in a cross-sectional direction perpendicular to the detachable snap-fit ​​assembly.

[0011] In one possible implementation, the grip assembly includes a grip fixing member, a first connecting rod, a second connecting rod, and a handle, wherein the grip fixing member is integrally connected to the main body segment, one end of the grip fixing member is connected to one end of the handle via the first connecting rod, and the other end of the grip fixing member is connected to the other end of the handle via the second connecting rod.

[0012] In one possible implementation, the first connecting rod and the second connecting rod are positioned along the length of one end of the main body segment.

[0013] In one possible implementation, the handle has a C-shaped cross-section.

[0014] In one possible implementation, the C-shaped cross-section includes a C-shaped main body segment, a first arc segment, and a second arc end. One end of the C-shaped main body segment is integrally connected to the first arc segment, and the other end of the C-shaped main body segment away from the first arc segment is integrally connected to the second arc end. On the cross-section at one end of the handle, the other end of the C-shaped main body segment away from the first arc end is also connected to one end of the grip fixing member via a first connecting rod. On the cross-section at the other end of the handle along its length, the other end of the C-shaped main body segment away from the first arc segment is also connected to the other end of the grip fixing member via a second connecting rod.

[0015] This application provides a detachable handling handle, comprising a detachable snap-fit ​​assembly and a handle assembly. The detachable snap-fit ​​assembly has a multi-bend semi-closed cross-section, forming a detachable connection with the edge of the object to be moved through a semi-closed notch. The handle assembly is integrally connected to the detachable snap-fit ​​assembly. By designing the detachable snap-fit ​​assembly, a detachable connection between the handle and the object to be moved is achieved. For objects of the same size, only one pair of handles is needed to move all objects, improving handle utilization, reducing the production cost of energy storage devices, and minimizing external space occupation.

Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0021] In the production, assembly, or field deployment of energy storage devices (such as battery packs), multiple energy storage units (i.e., energy storage stacking systems) are often stacked layer by layer to form an overall energy storage module. In traditional technology, each energy storage stacking system is fixedly equipped with a pair of dedicated handles, which workers use to move and stack the system. However, this traditional approach has at least the following drawbacks: (1) The handle only serves a portable function during the stacking installation process. Once the stacking is completed, the handle loses its actual function and remains idle on the energy storage stacking system for a long time without participating in the operation of subsequent equipment. In other words, the handle has a single function and low utilization rate.

[0022] (2) Each energy storage stack system needs to be equipped with a pair of handles independently. As the number of energy storage systems increases, the material cost, processing cost and installation cost of the handles increase significantly, which increases the overall production cost of the energy storage equipment.

[0023] (3) Fixed handles will occupy additional external space required by the overall energy storage module, which may affect the compactness of the overall structure after stacking, or cause inconvenience to subsequent equipment maintenance.

[0024] Based on this, this application provides a detachable handling handle. By designing a detachable snap-fit ​​component, a detachable connection between the handle and the object to be moved is achieved. For objects of the same size, only one pair of handles is needed to move all objects, improving handle utilization, reducing the production cost of energy storage devices, and reducing external space occupation. Specifically, as follows: Please see Figure 1 , Figure 1 This illustration shows one of the structural schematic diagrams of a detachable carrying handle provided in an embodiment of this application. Figure 1 As shown in the embodiment of this application, the detachable handling handle includes a detachable snap-fit ​​component 1 and a handle component 2. The cross-section of the detachable snap-fit ​​component 1 is a multi-bend semi-closed shape. The detachable snap-fit ​​component 1 forms a detachable connection with the edge of the object to be transported through the semi-closed notch. The detachable snap-fit ​​component 1 has a first preset length L1 in the vertical direction of its cross-section. The handle component 2 is integrally connected with the detachable snap-fit ​​component 1.

[0025] like Figure 1 As shown, the detachable handling handle provided in this application is snapped onto the edge 3 of the object to be transported by a detachable snap-fit ​​component 1, and can achieve a detachable connection with the edge 3 of the object to be transported through the semi-closed notch of the detachable snap-fit ​​component 1. Generally, the detachable snap-fit ​​component 1 has a first preset length L1 in the vertical direction of its cross section that is smaller than the length L3 of the edge 3 of the object to be transported.

[0026] Please see Figure 2 , Figure 2 This illustration shows one of the cross-sectional schematic diagrams of a detachable snap-fit ​​assembly provided in an embodiment of this application. For example... Figure 2 As shown, for the cross-section of the detachable snap-fit ​​assembly, its corresponding multi-bend semi-closed shape includes a main body segment A1, a first extension segment A2, and a second extension segment A3. One end of the main body segment A1 is integrally connected to one end of the first extension segment A2, and a first bend angle is formed at the junction of the main body segment A1 and the first extension segment A2. The other end of the main body segment A1, away from the first extension segment A2, is integrally connected to one end of the second extension segment A3, and a second bend angle is formed at the junction of the main body segment A1 and the second extension segment A3. Figure 2 In the illustrated embodiment, the first bending angle is smaller than the second bending angle.

[0027] The first extension segment A2 and the second extension segment A3 are arranged opposite to each other, and an opening with a multi-bend semi-closed shape is formed between the other end of the first extension segment A2 and the other end of the second extension segment A3, so that the detachable snap-fit ​​assembly 1 forms a notch of a first preset length L1 in the vertical direction of its cross section.

[0028] In one specific embodiment provided in this application, the surfaces of the main body segment A1, the first extension segment A2, and the second extension segment A3 may be wavy, serrated, or smooth, and no specific limitation is made here.

[0029] In a preferred embodiment, such as Figure 2 As shown, the other end of the first extension segment A2, which is away from the main body segment A1, is bent to form a hook-shaped structure A4 that fits into the edge 3 of the object to be transported.

[0030] The semi-closed opening is formed by the hook-shaped structure A4 and the second extension A3.

[0031] In a specific embodiment, when the detachable handling handle is used, the hook-shaped structure A4 engages with the edge 3 of the object being transported, and as... Figure 2 As shown, after the hook-shaped structure A4 fits into the edge 3 of the object to be transported, the other end of the second extension A3, away from the main body A1, abuts against the side wall 4 of the object to be transported to which the edge 3 belongs.

[0032] Please see Figure 3 , Figure 3 This is a second cross-sectional schematic diagram of a detachable snap-fit ​​assembly provided in an embodiment of this application. For example... Figure 3 As shown, the first distance D1 between the other end of the second extension segment A3 away from the main segment A1 and the hook structure A4 is less than the width W of the edge 3 of the object to be transported.

[0033] The width W of the edge 3 of the object to be moved is set to be greater than D1, which reduces the possibility of the detachable handle falling off the edge 3 when the detachable handle is under force.

[0034] In a preferred embodiment, such as Figure 1 As shown, one end of the grip assembly 2 is integrally connected to the detachable snap-fit ​​assembly 1, and the other end of the grip assembly 2 forms a handle. The grip assembly 2 has a second preset length L2 in the cross-sectional direction perpendicular to the detachable snap-fit ​​assembly 1.

[0035] Please see Figure 4 , Figure 4 This is a second schematic diagram of a detachable carrying handle provided in an embodiment of this application. (See attached diagram.) Figure 4 As shown, the grip assembly 2 includes a grip fixing member 21, a first connecting rod 22, a second connecting rod 23, and a handle 24. The grip fixing member 21 is integrally connected to the main body section A1 of the detachable snap-fit ​​assembly 1. One end of the grip fixing member 21 is connected to one end of the handle 24 through the first connecting rod 22, and the other end of the grip fixing member 21 is connected to the other end of the handle 24 through the second connecting rod 23.

[0036] The handle 24 of this application is designed with an exemplary rough surface or with a corresponding anti-slip strap wrapped around it to increase the friction between the hand and the handle 24.

[0037] Preferably, the first connecting rod 22 and the second connecting rod 23 are arranged along the length of one end of the main body segment A1 of the detachable snap-fit ​​assembly 1.

[0038] like Figure 4 As shown, the handle 24 has a C-shaped cross section, which includes a C-shaped main body section B1, a first arc-shaped section B2, and a second arc-shaped end B3. One end of the C-shaped main body section B1 is integrally connected to the first arc-shaped section B2, and the other end of the C-shaped main body section B1 away from the first arc-shaped section B2 is integrally connected to the second arc-shaped end B3.

[0039] On one end of the handle 24, the other end of the C-shaped main body section B1, which is away from the first arc-shaped section B2, is also connected to one end of the grip fixing member 21 via the first connecting rod 22.

[0040] On the cross-section of the other end of the handle 24 along its length, the other end of the C-shaped main body segment B1, away from the first arc segment, is also connected to the other end of the grip fixing member 21 via the second connecting rod 23.

[0041] The first arc segment B2 is opposite to the second arc end B3.

[0042] In a preferred embodiment, such as Figure 4 As shown, a gap is formed between the end of the first arc segment B2 away from the C-shaped main body segment B1 and the end of the second arc segment B3 away from the C-shaped main body segment B1.

[0043] In another preferred embodiment, the end of the first arc segment B2 away from the C-shaped main body segment B1 is integrally connected to the end of the second arc segment B3 away from the C-shaped main body segment B1, so that the handle 24 forms a fully enclosed structure.

[0044] In this application, the handle 24 can be selected from either the above-mentioned notch structure or the fully enclosed structure according to actual needs, and no specific restrictions are made here.

[0045] In this application, the detachable snap-fit ​​component 1 can be a sheet metal part, a die-cast part, or an injection molded part, etc., and the handle component 2 can also be a sheet metal part, a die-cast part, or an injection molded part, etc. The material selection for the detachable handling handle can be based on actual needs, and will not be elaborated on here.

[0046] Based on the same concept, this application also provides a detachable handling handle assembly. The detachable handling handle assembly includes two detachable handling handles as provided in any of the above embodiments. Generally, two detachable handling handles are needed to move an object. The detachable handling handle assembly provided in this application is used for moving energy storage stacking systems / energy storage devices. The specific operation method is as follows: The two detachable handling handles are respectively secured to the opposite sides of the energy storage devices to be stacked using their respective detachable locking components. For details, refer to... Figure 2 For each detachable handle, the detachable snap-fit ​​component 1 corresponding to the detachable handle is snapped onto the corresponding edge in a forward / clockwise direction, ensuring a secure connection.

[0047] In one specific embodiment, for each detachable handling handle, the installation and mating process between the detachable handling handle and the edge of the energy storage device is performed in the following manner: exist Figure 2 In the indicated direction, rotate the detachable handling handle clockwise / forward to rotate the hook structure A4 corresponding to the detachable snap-fit ​​assembly 1 to the 5 o'clock position. Insert the hook structure A4 into the edge of the energy storage device along this direction. The edge of the energy storage device fits into the hook structure A4, thus completing the installation process between the detachable handling handle and the edge of the energy storage device.

[0048] After installation, the staff can lift the detachable handling handle upwards by holding the corresponding handle 24 of the detachable handling handle. At this time, the detachable handling handle rotates counterclockwise, and the other end of the second extension section A3 of the detachable handling handle, away from the main body section A1, abuts against the side wall of the energy storage device at the edge. In this way, the energy storage device can be moved to the target location, completing the stacking of the energy storage system / energy storage device.

[0049] As exemplified by this application, the detachable handling handle provided in this application can be applied to the handling process of objects with edges to be moved, and no specific limitations are made herein.

[0050] After the energy storage device is moved to the target location, for each detachable handling handle, the disassembly and engagement process between the detachable handling handle and the edge of the energy storage device is performed in the following manner: exist Figure 2In the indicated direction, rotate the detachable handle clockwise / forward to rotate the hook-shaped structure A4 corresponding to the detachable snap-fit ​​assembly 1 to the 5 o'clock position. During the rotation, the other end of the second extension section A3 corresponding to the detachable handle, away from the main body section A1, separates from the side wall of the energy storage device to which the edge belongs. After the hook-shaped structure A4 corresponding to the detachable snap-fit ​​assembly 1 is rotated to the 5 o'clock position, detach the hook-shaped structure A4 from the edge of the energy storage device along this direction. This completes the installation process between the detachable handle and the edge of the energy storage device, releases the snap-fit ​​between the detachable handle and the energy storage system, and removes the detachable handle.

[0051] Apply the two removed detachable handling handles to the next energy storage system / energy storage device, repeating the process until the stacking of energy storage systems / energy storage devices is complete.

[0052] Therefore, in the stacking process of energy storage systems / energy storage devices, only a pair of detachable handling handles provided by this application are needed. There is no need to set up corresponding handles for each energy storage system / energy storage device separately, which reduces the overall production cost of energy storage devices and improves the utilization rate of handles in the entire stacking process. After the stacking is completed, the handles are avoided from occupying the external space of the energy storage system, improving the compactness of the overall structure after stacking and providing convenience for subsequent equipment maintenance.

[0053] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
