Description

Technical Field

[0001] The utility model relates to the technical field of energy storage equipment, in particular to an energy storage battery module plug-in structure. Background Art

[0002] Energy storage devices are often composed of battery modules and storage structures. The storage structures often store battery modules by providing insertion slots that are compatible with the battery modules. To facilitate access to the battery modules, a plug-in installation method is often used. The battery modules are inserted into the corresponding insertion slots, and their external interfaces are connected to the internal interfaces of the energy storage device. To reduce resistance during the insertion and removal of the battery modules and make the insertion and removal process easier, a certain gap is often left between the inner wall of the insertion slot and the inserted battery module. As a result, when the energy storage device is subjected to external forces, the battery module inevitably shakes slightly within the insertion slot. Due to the plug-in relationship between the external interface and the internal interface of the slot, the external interface of the battery module is easily damaged and loosened, affecting the service life of the battery module.

[0013] The present invention will be further described below in conjunction with the accompanying drawings.

[0014] As attached Figure 1-2 The energy storage battery module insertion structure includes an insertion cavity 2 located inside the energy storage device 1, with an insertion port 3 provided at the bottom of the insertion cavity 2, which is inserted and matched with the external port 41 of the battery module 4; a support structure 5 is provided on the bottom surface of the insertion cavity 2, which fits the bottom side surface of the battery module 4; the upper end opening of the energy storage device 1 constitutes the insertion port of the insertion cavity 2, and a pressure cover 6 is provided at the insertion port, which presses the upper end surface of the battery module 4; an elastic abutment 7 is provided on the side wall of the insertion cavity 2, which fits against the side wall of the battery module 4; a limit strip 8 is provided on the side wall of the battery module 4, and a card slot 73 adapted to the limit strip 8 is provided on the elastic abutment 7. A single energy storage device 1 can be provided with multiple insertion cavities 2.

[0015] This solution is provided with an insertion cavity for installing the battery module, and a constraint limit structure is provided in the cavity to maintain the stability of the battery module in the cavity, reduce the influence of external forces, and ensure the smoothness of the plug-in and pull-out process. Specifically, a support structure is provided to fill the gap between the end face of the battery module plug-in interface and the inner wall of the insertion cavity, and the battery module is pressed tightly against the support structure by the clamping limit of the pressure cover, ensuring the tight plug-in relationship between the external interface and the plug-in interface while reducing the swing of the battery module relative to the plug-in interface, thereby ensuring the stability of the plug-in and avoiding the battery module from shaking due to external forces and causing damage to the external interface of the battery module. The side walls of the battery module are supported by elastic abutments, which can be used to offset external forces and have a shock-absorbing effect, making the position of the battery module in the insertion cavity more stable. At the same time, sufficient gap space is left between the battery module and the inner wall of the insertion cavity to facilitate heat dissipation of the battery module. The corresponding locking devices of the limit strip and the card slot cooperate to constrain the lateral movement of the battery module in the insertion slot, further constrain the position of the battery module in the insertion cavity, minimize the impact of external force on the relative position of the battery module in the cavity, effectively protect the stable connection between the external interface and the insertion interface, and extend the service life of the battery module.

[0016] The elastic abutment member 7 is a multi-bend elastic sheet. The bottom end of the elastic abutment member 7 is fixedly connected to the inner wall of the insertion cavity 2. The middle portion of the elastic abutment member 7 is a contact section 72 that contacts the battery module 4, and the upper portion of the elastic abutment member 7 is a guide section 71 that tilts away from the battery module 4. Before the battery module is inserted, the two opposing elastic sheets are tilted close together, forming an insertion space that is narrow at the top and wide at the bottom between the abutment sections of the two elastic sheets. The width of the gap at the bottom matches the width of the battery module. During the insertion process, the two elastic sheets are stretched apart by the cooperation of the limiting bars on the sides of the battery module and the guide sections at the top of the elastic sheets. Once fully inserted, the limiting bars precisely engage the corresponding slots on the elastic sheets, and the abutment sections of the elastic sheets precisely abut against the side walls of the battery module. Under the restoring force of the elastic sheets, a clamping force is generated on the battery module, maintaining the battery module in a stable position.

[0017] The top of the guide slide section 71 rests against the bottom side of the gland 6. The gland can further constrain the top of the elastic sheet, causing the guide slide section to bend slightly outward relative to the abutment section, thereby enhancing the elastic sheet's clamping force on the battery module. At the same time, the elastic restoring force of the guide slide section generates a reverse thrust on the gland, ensuring the gland's sealing and the safety of energy storage.

[0018] Elastic gaskets 9 are provided on the contact surfaces of the support structure 5, the gland 6, and the elastic abutment member 7 with the battery module 4. The elastic gaskets 9 on the elastic abutment member 7 are located on both sides of the slots 73. The elastic gaskets provide a certain amount of buffer space, reduce the rigid restraint on the battery module, increase the friction between the contact surfaces, and effectively protect the battery module.

[0019] The upper end of the limit bar 8 is configured as an inclined guide surface. When the battery module is pulled out, the limit bar is facilitated to disengage from the slot and to open the elastic abutment members on both sides, so that the elastic gasket is separated from the side wall of the battery module, reducing the resistance during extraction and making the battery module easier to extract.

[0020] Several limiting plates 10 surround the outer side of the plug-in port 3, supporting the bottom surface of the battery module 4. The limiting plates guide the insertion and removal of the external port and reinforce the plug-in joint after insertion, further protecting the external port and extending the service life of the battery module.

[0021] The above descriptions of directions, such as top, bottom, top, etc., only correspond to the directions shown in the drawings and are used to clearly express the structure. The actual insertion cavity can be arranged in any direction, and the insertion direction can be adjusted according to actual storage needs.

[0022] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
