Abstract: A fixing device of electronic element comprises a main body and a hook. The main body contains an electronic element and comprises a guiding groove and a block. The guiding groove is disposed at a sidewall of the main body. The block is disposed on a side of the guiding groove and has a blocking surface. The hook is disposed in the guiding groove to fix the electronic element and comprises a body, a pressing portion, a cantilever and a cushion structure. The pressing portion is disposed on one end of the body. The cantilever has a contact surface to press the blocking surface. Two ends of the cushion structure are connected to the other end of the body and the cantilever, respectively.

Abstract: A battery device is provided, which includes a fixing frame, a battery and a heat dissipating structure. The fixing frame includes a first plane, a second plane and a third plane. The first plane stands apart from the second plane, and the third plane connects the first plane and second plane. A receiving space is formed between the first and the second planes. The battery is disposed in the receiving space. The heat dissipating structure includes a plate and a block connected to the plate. The plate is disposed on the second plane and comes into contact with the battery. The block is disposed on the third plane and has an input hole and an output hole for liquid to pass therethrough. With this arrangement, the heat dissipating structure can quickly dissipate heat from the battery by the liquid flow. A battery device module is also provided in this disclosure.

Abstract: A battery module includes a first battery bracket, a second battery bracket, and a liquid cold heat-dissipating mechanism. The first battery bracket and the second battery bracket are stacked on each other. Each of the first battery bracket and the second battery bracket includes plural hollow portions for accommodating plural battery cells. The liquid cold heat-dissipating mechanism is used for removing heat from the plural battery cells. The liquid cold heat-dissipating mechanism includes an input channel, an output channel, a first flow-channel plate, at least one first connecting member, and at least one second connecting member. After a cooling liquid is introduced into the input channel, the cooling liquid is sequentially transferred through the first end of the first flow-channel plate, the first flow channel, the second end of the first flow-channel plate and the second connecting member, and discharged from the output channel.

Abstract: A battery module including a plurality of cell units is disclosed. Each cell unit has a first surface and a second surface, and the cell units are stacked alone a direction. The cell unit includes a frame, at least one cell and at least two conductors. The frame has at least a first accommodating recess located at the first surface. The cell having two tabs is accommodated in the first accommodating recess. The conductors and the frame are connected at the second surface, and each conductor has a connecting portion located at the first surface. The connecting portions of the two conductors are ultrasound welded with the two tabs respectively. The conductors of adjacent cell units are fixed to each other.

Abstract: A method of manufacturing an end cap of a linear guideway can keep the finished end cap from constant deformation during storage. The method is to arrange a rib on the intermediate product during the manufacturing process, the rib can be cut away from the intermediate product after stress relief, and thus preventing severe deformation of the intermediate product caused by stress relief.

Abstract: A roller retainer module includes an upper and lower thin boards disposed flush with each other, with a plurality of separated space each having a hexagonal cell structure, in which a corresponding roller is fixed in position. Since such cell structure may not exert a large friction force on the roller, the roller may be maintained with its direction changing function.
