The application relates to the technical field of batteries, and discloses a battery cell and a battery pack. The battery cell comprises a shell with an open end, the open end of the shell forms a first end face, a cover plate assembly comprises a cover plate body, the cover plate body comprises a body part and a boss, the boss is connected to one side of the body part in the Z direction, the body part is lapped on the first end face, the boss extends into the inner cavity of the shell, and the boss is arranged in a spaced mode with the shell; a guide ring is sleeved on the boss and clamped between the boss and the shell, and the height of the guide ring in the Z direction is greater than the thickness of the boss in the Z direction. By sleeving the guide ring on the outer circumferential side of the boss, the area where the guide ring is in contact with the inner wall of the shell forms a support area, the setting of the guide ring increases the support height of the inner wall of the shell, improves the support stability, reduces the strain of the heat affected zone without increasing the thickness of the cover plate body, avoids the abnormal problem that the welding heat affected zone of the shell is prone to cracking under the action of a large fatigue stress, and improves the safety of the battery cell.

The utility model discloses an old man turning-over device relates to medical auxiliary instrument technical field, including frame body part, control part and lifting part, replace manual heavy physical operation: device relies on the drive motor of control part, screw rod and abutment plate cooperation, through motor drive screw rod rotation, drive abutment plate to lift to promote first side plate, second side plate rotation around pivot, realize the mechanical lifting of old man body position and turn over, replace traditional manual auxiliary turning-over's heavy physical labor. Without nursing staff consuming physical strength to move or lift the old man, solve the problem of nursing staff fatigue caused by frequent turning over at night, reduce the work burden of long-term nursing, adapt to the scene of family lack of professional nursing staff.

The application relates to the fields of biological medicine and tissue engineering materials, and particularly discloses a Janus microneedle capable of promoting inflammation subsiding and blood vessel regeneration of a diabetic wound surface as well as a preparation method and application of the Janus microneedle, the microneedle is a double-layer structure, the upper layer is loaded with an SLC7A11 inhibitor and an apoptotic body, and the lower layer is loaded with an engineered exosome overexpressing miR-17-5p. Through a unique double-layer hydrogel matrix design and a two-phase crosslinking process, the Janus microneedle realizes rapid release of active ingredients in the upper layer in the early healing stage to promote inflammation subsiding and phagocytosis, and slow release of active ingredients in the lower layer in the middle and late healing stage to continuously promote angiogenesis. The microneedle patch can intelligently simulate and synergistically regulate the natural timing of wound healing, solves the problem of space-time disconnection of the existing single therapy, and provides a novel and precise delivery strategy for efficient repair of chronic and difficult-to-heal wounds such as diabetes.

The utility model discloses a kind of arc slide plate base support structures of displacement trolley, which is used to slide support to mould frame when moving mould frame. The arc slide plate base support structure includes slide and slide mounting seat, the bottom surface of slide is arc, arc support plate is provided in the inside of slide mounting seat, the arc bottom surface of slide and the arc support plate surface contact, so that arc support plate can provide enough support effect (surface contact, provide enough stress surface) for slide, and slide can also slide along arc support plate in arc direction, to adapt to the pitch angle change of mould frame in moving process.

The utility model relates to photovoltaic power generation technical field discloses the fastening device for photovoltaic module, including support structure, first pressure structure, second pressure structure and connecting structure, support structure is located between photovoltaic board and support purlin, and the both ends along the first direction are respectively with photovoltaic board and support purlin and abut; first pressure structure and photovoltaic module and support structure are away from the side of support purlin and all abut; Second pressure structure sets up at the side of support purlin away from photovoltaic board, connecting structure connects first pressure structure, support structure and second pressure structure in proper order, the utility model not only has guaranteed the direct close connection between photovoltaic board and support purlin, still through multiple pressure and support mechanism, has improved the stability and durability of whole structure, guarantees the firmness of connection between photovoltaic board and support purlin together, ensures that photovoltaic module can bear the impact of bad weather, has guaranteed the safe operation of photovoltaic power station, and has reduced the maintenance cost of photovoltaic module.
