The utility model relates to the technical field of touchpads, in particular to a touchpad assembly and a notebook computer. The touchpad assembly includes an upper cover and a stiffener. The reinforcing piece is connected to the upper cover, the reinforcing piece is used for supporting the bottom of the touch panel, the reinforcing piece is further provided with a first buckling piece, and the first buckling piece is used for being connected with the bottom cover. Wherein the upper cover and the reinforcing piece are of an integrally-formed structure. The touchpad assembly is provided with the reinforcing part connected to the upper cover, and the reinforcing part can support the touchpad at the bottom of the touchpad, so that the touchpad can be clamped between the upper cover and the reinforcing part to fix the touchpad. The touch panel can be stably installed on the upper cover. Furthermore, the upper cover and the reinforcing piece are of an integrally-formed structure, and the upper cover and the reinforcing piece can be manufactured through one mold in the process of manufacturing the touch pad assembly, so that the mold opening frequency of the structure for supporting the touch pad can be reduced, and the manufacturing cost of the touch pad assembly is low.

A comb plate structure for welding side lugs and a welding fixture for lead-acid batteries are disclosed. The positive and negative electrode plates of the battery mate with the comb teeth of the comb plate. Lead-biased parts and straight terminals are placed in the grooves of the comb plate. The fixture includes a feeding structure for placing the comb plate, a clamping structure for clamping the electrode group, and a frame for placing the clamping structure. The electrode group is fixed by manually turning the handwheel of the frame, and the comb plate and lugs are fixed by manually turning the handwheel of the feeding structure to weld the lead-biased parts and the lugs of the electrode group together, thereby assembling the battery. This structure is suitable for electrode plates with side lug structures, which can save R&D costs, shorten development time, and quickly verify design schemes.

This invention relates to an electrolytic cell electrode plate and its manufacturing process, comprising a metal electrode plate and a first sealing ring; the metal electrode plate defines a mutually perpendicular X-plane and a Y-plane; a flow channel and a first annular sealing groove are respectively provided on two end faces parallel to the X-plane; an oxygen inlet and a water outlet are provided on the first end face, communicating with the flow channel on that end face and along the Y-plane direction, and a hydrogen inlet is provided on the second end face, communicating with the flow channel on that end face and along the Y-plane direction; there are two first sealing rings, respectively adapted to the shape and size of the sealing grooves on the first and second end faces, and integrally vulcanized with the metal electrode plate. This invention employs a structure that integrally vulcanizes the sealing ring and the metal electrode plate with the sealing groove, processing two components that originally required high-precision tight splicing into a single unit, reducing the risk of hydrogen leakage from the electrolytic cell while improving the stacking efficiency of the electrolytic cell and enhancing the service life and performance of the PEM electrolytic cell.
