Abstract: The present invention belongs to the field of wigs, and discloses a detachable wig headgear, including a rear end part, a front end part connected to the rear end part, and a zipper provided between the rear end part and the front end part. In the present invention, a zipper structure is adopted to detachably connect the front end part and the rear end part. If there is a need to change the styling of wigs or the wig headgear is damaged, the wig headgear needs to be replaced. The front end part and the rear end part of the wig headgear may be split by the zipper. Then, a part that is needed to be changed or a damaged part is replaced. Finally, the zipper is used to connect the front end part and the rear end part, which saves costs significantly.

Abstract: A battery housing includes: a tray including a first channel; an explosion-proof valve disposed on the tray, the first channel being in communication with the explosion-proof valve; at least one module transverse beam disposed in the tray and including an accommodating portion, at least a part of a bottom of the accommodating portion being depressed downward to form a groove, and an opening disposed at at least one end of the groove along a length direction of the module transverse beam; and a liquid cooling plate connected to an outside of a bottom of the module transverse beam, at least one connection channel being formed between the liquid cooling plate and the module transverse beam, and the opening of the at least one module transverse beam being in communication with the first channel through the connection channel.

Abstract: A battery assembly, a battery pack and a vehicle are provided. The battery assembly includes: multiple cells; a connecting member, where the cells is electrically connected to each other through the connecting member; and a thermally conductive member, where the cell has a housing, the thermally conductive member is provided between the connecting member and the housing, and the thermally conductive member is thermally conductively connected to the connecting member and the housing.

Abstract: The present disclosure relates to a composite temperature control plate and a battery pack. The composite temperature control plate includes a temperature control layer and a protective layer. The temperature control layer is configured to lower or raise a temperature of the battery pack. The protective layer is laminated and fixed on the temperature control layer. The protective layer includes a heat insulating layer. The heat insulating layer is made of a heat insulating material. The protective layer includes a mounting portion extending at least to an periphery of the temperature control layer. The mounting portion is configured to connect with outside.

Abstract: Provided are Streptococcus thermophilus for producing ?-aminobutyric acid and an application thereof. The Streptococcus thermophilus for producing ?-aminobutyric acid is named Streptococcus thermophilus ST 36 and is preserved in the Institute of Microbiology of the Chinese Academy of Sciences, the preservation number being CGMCC NO. 20676, and the preservation date being 18 Sep. 2020. Also provided are a screening method for Streptococcus thermophilus for producing ?-aminobutyric acid, a preparation method for a dairy product containing ?-aminobutyric acid, and a dairy product containing ?-aminobutyric acid prepared by using the preparation method. The Streptococcus thermophilus for producing ?-aminobutyric acid has strong ?-aminobutyric acid synthesis capability and short fermentation time, and the prepared dairy product contains rich ?-aminobutyric acid.

Abstract: An electromagnetic relay which is improved in arc blocking performance without being increased in size is desired. An electromagnetic relay according to the present invention is provided with a fixed contact, a moving contact which is movable respect to the fixed contact, a pair of magnets which is arranged at the side of the fixed contact and the moving contact so that pole faces with mutually reversed polarity are separated from and face each other and a pair of arc cooling plates which is arranged in a spaces between the magnets and which has first surfaces which face each other across a gap and second surfaces which face a pole face of either of the magnets, respectively.

Abstract: An electromagnetic relay includes a first stationary contact; a second stationary contact that is aligned with the first stationary contact in a first direction; a first movable contact that is movable toward/away from the first stationary contact in a second direction perpendicular to the first direction; a second movable contact that is movable toward/away from the second stationary contact in the second direction; and a first permanent magnet and a second permanent magnet that face each other. A first contact part, formed by the first stationary contact and the first movable contact, and a second contract part, formed by the second stationary contact and the second movable contact, are interposed between the first permanent magnet and the second permanent magnet in the first direction. The first permanent magnet and the second permanent magnet extend in a third direction, which is perpendicular to the first direction and the second direction.
