Abstract: The present application relates to the technical field of lithium batteries. Disclosed is a lateral-weld soft connector having a pole column. The connector comprises a first connector, which a top end face configured to face upward; a pole column which extends upwards protrudes out of the top end face of the first connector; a second connected extending outwards and connected to a cell is provided at one side of the first connector; the second connector is bent downwards with respect to the first connector and is disposed at a side edge of the cell.

Abstract: The present application relates to the technical field of battery explosion-proof and discloses an explosion-proof sheet including a sheet body. A recess loop in a shape of an enclosed loop is formed in the sheet body, and a flip portion is formed in the sheet body within a region enclosed by the recess loop. A score in a shape of a non-enclosed loop is arranged within the recess loop, the score extends along a circumference direction of the recess loop, and a portion of the recess loop located between two ends of the score forms a connection segment configured for turning over the flip portion.

Abstract: The present invention relates to dual-lens eyeglasses including an eyeglass frame and two lens units permanently installed on the eyeglass frame. Each lens unit includes two lenses arranged in optical alignment with each other. The lenses can be optical lenses or sunglass lenses. The optical lenses can be selected from known lenses such as corrective lenses, myopic corrective lenses, reading glasses lenses, progressive lenses, etc. The sunglass lenses can be selected from polarized lenses, tinted lenses, or photochromic lenses. Without the use of sub-frames, two lens units are permanently installed on eyewires of the eyeglass frames, enhancing the integration effect of the eyeglass frames. In addition, each lens is directly fixed and installed on the eyeglass frames, so that the installation is reliable and the lenses will not fall off easily. Furthermore, the lenses can be easily installed on full-rim, half-rim or rimless eyeglass frame.
