Description

Technical Field

[0001] This utility model relates to the field of energy storage battery technology, specifically to a stacked battery assembly with a handle. Background Technology

[0002] With the rapid development of electric vehicles, energy storage systems, and other fields, rechargeable battery packs, as their core power or energy storage units, are evolving towards higher energy density and higher integration. In order to accommodate more cells in a limited space, multiple battery modules are usually stacked to build battery packs.

[0003] In existing battery pack designs, a common approach is to stack battery modules vertically. To simplify the assembly process and improve production efficiency, blind-mating connectors are typically used to achieve electrical interconnection between the stacked battery modules. "Blind-mating" refers to the process where, during module mating, the male and female connectors automatically align and engage without the need for precise visual positioning, relying solely on a mechanical guiding structure.

[0004] However, existing stacking installation methods have significant technical drawbacks. Due to the substantial weight of the battery modules, simple positioning structures alone are insufficient for stable and precise guidance when stacking them vertically. During installation, the lower battery modules cannot provide effective lateral constraint to the upper modules, making relative misalignment or overall skewness between modules highly likely. This misalignment directly causes blind-mating connectors to experience additional lateral stress at the moment of mating, resulting in a stiff and difficult insertion / removal feel, impacting the customer's assembly experience. More seriously, it can cause bending, wear, or even breakage of the connector pins, posing safety risks such as connection failure and short circuits. Furthermore, collision damage to the connectors increases maintenance costs and reduces the reliability of the battery pack.

[0005] In view of this, it is necessary to improve the existing stacked battery assemblies to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a stacked battery assembly with a handle to solve the problem that existing stacked batteries suffer additional lateral stress when blind-mating connectors are subjected to misalignment during stacking.

[0007] To achieve the above objectives, this utility model provides a stacked battery assembly with a handle. The stacked battery assembly with a handle includes at least two battery modules stacked vertically. Each battery module includes a battery box, a first connector disposed at the upper end of the battery box, a second connector disposed at the lower end of the battery box, a handle disposed at the upper end of the battery box, and a receiving cavity disposed at the lower end of the battery box. When the two battery boxes are stacked vertically, the handle of the lower battery box is inserted into the receiving cavity of the upper battery box and abuts against the upper battery box along the length and width directions. The first connector of the lower battery box is inserted into and engages with the second connector of the upper battery box.

[0008] As a further improvement of this utility model, each of the battery boxes is provided with two handles and two receiving cavities, and the two handles are spaced apart along the length of the battery box.

[0009] As a further improvement of this utility model, the second connector is arranged adjacent to one of the receiving cavities.

[0010] As a further improvement of this utility model, the handle and the battery box are detachably and fixedly connected by fastening screws.

[0011] As a further improvement of this utility model, the handle has connecting holes through both ends in the width direction and in the height direction, and the battery box has fixing screw holes. The fastening screw passes through the connecting holes and is threaded into the fixing screw holes.

[0012] As a further improvement of this utility model, the first connector includes a plug-in terminal and a plug-in housing surrounding the plug-in terminal, the plug-in housing protruding upward from the top of the battery box.

[0013] As a further improvement of this utility model, the stacked battery assembly with handle also includes a limiting screw. A limiting hole is provided on the battery box, and the limiting hole communicates with the receiving cavity. When the upper and lower battery boxes are stacked, the limiting screw is inserted from the limiting hole and abuts against the handle of the lower battery box in the height direction.

[0014] As a further improvement of this utility model, the handle is ring-shaped, and the limiting screw is inserted into the middle of the handle.

[0015] As a further improvement of this utility model, the battery box also includes a threaded ring fixed in the receiving cavity. The threaded ring is fixed on the battery box and coaxially arranged with the limiting hole. The threaded ring is used to be threadedly connected with the limiting screw.

[0016] As a further improvement of this utility model, a clearance groove extending vertically is provided on the outer side of the handle. When the upper and lower battery boxes are stacked, the clearance groove is used to make way for the threaded ring.

[0017] The beneficial effects of this utility model are: the stacked battery assembly with handle of this utility model ensures horizontal stability by inserting and resisting the handle with the receiving cavity, which facilitates the insertion and cooperation of the first connector and the second connector, and does not bear additional lateral stress during insertion.

Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] like Figures 1 to 8 As shown, the stacked battery assembly 100 with handle of this utility model includes at least two battery modules 1 stacked vertically.

[0023] The battery module 1 includes a battery box 11, a first connector 12 disposed at the upper end of the battery box 11, a second connector 13 disposed at the lower end of the battery box 11, a handle 14 disposed at the upper end of the battery box 11, and a receiving cavity 15 disposed at the lower end of the battery box 11.

[0024] When the two battery boxes 11 are stacked, the handle 14 of the lower battery box 11 is inserted into the receiving cavity 15 of the upper battery box 11 and abuts against the upper battery box 11 along the length and width directions. The first connector 12 of the lower battery box 11 is inserted into and engaged with the second connector 13 of the upper battery box 11.

[0025] The handle 14 of the lower battery compartment 11 inserts into the receiving cavity 15 of the upper battery compartment 11, and abuts against it in the length and width directions, forming a mechanical lock. This effectively prevents the stacked modules from shifting or shaking in the horizontal direction, improves the overall structure's vibration and impact resistance, ensures stable stacking, and prevents the first connector 12 and the second connector 13 from experiencing additional lateral stress during insertion, thus avoiding damage or breakage. The insertion design of the handle 14 and the receiving cavity 15 acts as a guide mechanism, making the stacking process fast and accurate, reducing errors and time spent on manual alignment, and improving installation efficiency.

[0026] When stacked, the first connector 12 of the lower battery box 11 automatically engages with the second connector 13 of the upper battery box 11, achieving a plug-and-play electrical connection. No additional wiring is required, reducing installation complexity, preventing connection errors, and improving safety and reliability. The modular plug-in design supports rapid expansion or replacement of battery modules 1, facilitating system maintenance and capacity adjustment.

[0027] Each battery module 1 is equipped with a handle 14 for easy individual handling and operation; when stacked, the cooperation between the handle 14 and the receiving cavity 15 further simplifies the assembly and disassembly process and reduces maintenance costs. In addition, the top handle 14 after stacking facilitates the handling of the entire stacked battery assembly 100 with handles.

[0028] In this embodiment, the handle 14 serves the functions of positioning, limiting, and providing a grip for the user.

[0029] Each of the battery cases 11 is provided with two handles 14 and two receiving cavities 15, with the two handles 14 spaced apart along the length of the battery case 11. The two handles 14 arranged along the length direction facilitate gripping by the user. In some embodiments, the two handles 14 may also be arranged along the width direction.

[0030] The second connector 13 is disposed adjacent to one of the receiving cavities 15. In this embodiment, the second connector 13 is located near one end along its length.

[0031] The handle 14 and the battery box 11 are detachably and fixedly connected by fastening screws 16. The handle 14 of the topmost battery module 1 can be removed. The detachable handle 14 structure provides flexibility in use: during handling and stacking, the handle 14 is easy to grip and position; and after final installation, removing the topmost handle 14 keeps the top surface of the stacked components flat, which avoids the safety risks or space interference that may be caused by the protruding structure, and makes the appearance simpler, adapting to diverse installation environments and aesthetic requirements.

[0032] The handle 14 has connecting holes 141 extending through both ends in the width direction and through in the height direction. The battery box 11 has fixing screw holes 111. The fastening screws 16 pass through the connecting holes 141 and are threaded into the fixing screw holes 111. The method of fixing at both ends ensures that the handle 14 is subjected to uniform force, which significantly enhances the stability of the connection and the fatigue resistance, and improves the reliability of long-term use.

[0033] The first connector 12 includes a plug-in terminal 121 and a plug-in housing 122 surrounding the plug-in terminal 121. The plug-in housing 122 protrudes upward from the top of the battery box 11. In this embodiment, the plug-in housing 122 protrudes in the same direction as the handle 14, and the height of the plug-in housing 122 is less than the height of the handle 14, so that when the two battery modules 1 are stacked, the handle 14 can first protrude into the receiving cavity 15 for guidance and positioning.

[0034] The stacked battery assembly 100 with a handle also includes a limiting screw 3. A limiting hole 112 is provided on the battery box 11, which communicates with the receiving cavity 15. When the upper and lower battery boxes 11 are stacked, the limiting screw 3 is inserted through the limiting hole 112 and abuts against the handle 14 of the lower battery box 11 along the height direction. By directly abutting against the lower handle 14 with the limiting screw 3, the risk of the battery module 1 accidentally detaching from the receiving cavity 15 due to gravity or inertia during handling or impact is eliminated. This design adds a detachable rigid connection to the existing plug-in abutment, fixing the upper and lower boxes in the height direction as well, significantly improving the integrity and anti-separation capability of the stack. When disassembly is required, simply loosening the limiting screw 3 releases the vertical lock, ensuring safe and controllable operation and achieving a balance between secure fixation and convenient maintenance.

[0035] The handle 14 is ring-shaped, and the limiting screw 3 is inserted into the middle of the handle 14. The ring-shaped handle 14 makes it easy for the user to grip, and at the same time, it allows the limiting screw 3 to abut against the handle 14 from above and below. In this embodiment, the handle 14 and the battery 11 are arranged in a ring to allow the limiting screw 3 to be inserted.

[0036] The battery box 11 also includes a threaded ring 113 fixed in the receiving cavity 15. The threaded ring 113 is fixed to the battery box 11 and coaxially arranged with the limiting hole 112. The threaded ring 113 is used to thread with the limiting screw 3. In this embodiment, the threaded connection with the limiting screw 3 is achieved by setting an independent threaded ring 113.

[0037] In other embodiments, a screw hole can be directly made on the handle 14, and the limiting screw 3 can be directly threaded to the handle 14 instead of just abutting along the height direction.

[0038] The handle 14 has a vertically extending clearance groove 142 on its outward-facing side. When the two battery boxes 11 are stacked, the clearance groove 142 is used to make way for the threaded ring 113. To ensure positioning, the clearance groove 142 is only provided in the middle of the threaded ring 113, effectively preventing structural interference between the handle 14 and the threaded ring 113 when inserted into the receiving cavity 15. This ensures smooth stacking and protects the threaded ring 113 from scratches and damage, thus guaranteeing reliable engagement of the vertical locking mechanism.

[0039] The stacked battery assembly 100 with a handle of this invention features a handle 14 that engages with a receiving cavity 15, ensuring horizontal stability. Combined with a vertical locking mechanism formed by a limiting screw 3 and a threaded ring 113, this creates a rigid stack resistant to displacement in all directions, facilitating the insertion and engagement of the first connector 12 and the second connector 13 without incurring additional lateral stress. The adjacent arrangement of the connectors and the receiving cavity 15 allows for simultaneous electrical and mechanical alignment. The detachable design of the handle 14 and the clearance groove 142 enable rapid assembly. The modular stacking and detachable handle 14 support on-demand expansion and convenient maintenance. These features collectively optimize the battery system's space utilization, deployment efficiency, and operational safety.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
