Abstract: The disclosure relates to a fixing band for a battery module and a battery module. The fixing band comprises a first end portion, a connecting section and a second end portion which are arranged successively in an extending direction of the fixing band. The first end portion includes a body and engaging grooves which are protruded in a thickness direction of the body. The engaging grooves are integral with the body. The second end portion has engaging protrusions which are shaped to match the engaging grooves. The first end portion and the second end portion are laminated in the thickness direction and are engaged with each other by the engaging grooves and the engaging protrusions, so that the fixing band encloses an annular accommodation space.

Abstract: The present disclosure provides a lower box body, a battery box and a vehicle, the lower box body comprises a base body, a first protecting assembly, a mounting hole. The base body comprises a bottom plate portion, a side plate portion, eave portions. The first protecting assembly is provided at outside of the base body, fixed to the base body and is attached to the eave portion. The mounting hole penetrates the eave portion and the first protecting assembly. The first protecting assembly improves the entirety structural strength of the lower box. Because the mounting hole is formed by penetrating the eave portion and the first protecting assembly, the structural stability of the mounting location of the lower box body is improved, thereby making the mounting location of the lower box body not be prone to be deformed or damaged when the battery box is subjected to the external force.

Abstract: This application provides a battery box, a battery, and an electric device. The battery box includes a bottom plate and a frame. Each of two ends of the frame is provided with an opening, the opening at one end of the frame is connected to an edge of the bottom plate to form an accommodating space, and a light energy absorber is arranged on a side of the bottom plate in the accommodating space facing the accommodating space. According to the battery box provided in this application, in a case that an impact or a collision occurs at the bottom of the battery box, the light energy absorber can absorb the impact energy produced by the impact or collision, thereby greatly reducing the vibration, extrusion, and collision intensity of a battery module in the battery box. The light energy absorber provides buffering and protection for the battery module.

Abstract: The present disclosure provides a multifunctional high-voltage connector and a battery product, the multifunctional high-voltage connector comprises: an upper cover; a pedestal; a conductive connection structure; two mating terminals; and a harness assembly. The conductive connection structure is used to make the two mating terminals be connected in series, and the harness assembly is directly connected to one of the mating terminals. When the upper cover and the pedestal are assembled, the conductive connection structure is simultaneously in contact with the two mating terminals, thereby turning on the high-voltage circuit. When the battery product requires maintenance, the upper cover is directly detached from the base, thereby turning off the high-voltage circuit. The battery product can be electrically connected to an external device via the harness assembly. The multifunctional high-voltage connector integrates both a switch function and a high-voltage connection function, therefore the connection resistance is greatly reduced.
