4results about How to "Reduce post-use costs" patented technology

The application provides a battery device and a power utilization device, and belongs to the technical field of batteries. The battery device comprises a battery monomer, a first box body and a second box body. The first box body is provided with a mounting structure, and comprises a bearing plate and a first side wall plate. The bearing plate has a bearing surface for supporting the battery monomer in a first direction, and the first side wall plate is connected to the bearing plate and protrudes from the bearing surface. The second box body comprises a top plate and a second side wall plate. The top plate and the bearing plate are oppositely arranged in the first direction, and the second side wall plate is connected to the first side wall plate and the top plate. In the first direction, the size of the first side wall plate protruding from the bearing surface is less than one fourth of the maximum size of the second side wall plate. At least part of the top plate is raised in a direction away from the bearing plate and forms a protrusion. The cross section of the protrusion perpendicular to the extension direction of the protrusion is arc-shaped. The protrusion can release the stress received by the top plate, and is beneficial to alleviate the cracking or damage of the top plate during use.

This utility model discloses a double-through aluminum shell tenon and mortise structure, including an upper aluminum shell and a lower aluminum shell, with the upper and lower aluminum shells having the same surface area. Lower tenon blocks are fixedly installed on both sides of the lower surface of the upper aluminum shell, and tenon holes are opened on the sides of the lower tenon blocks. Lower tenon plates are fixedly installed at the center of the lower surface at both ends of the upper aluminum shell, and two symmetrically distributed tenon plate holes are opened on the lower tenon plates. Lower mortise grooves adapted to the lower tenon blocks are opened on both sides of the upper surface of the lower aluminum shell, and side through holes are opened at the bottom side of the lower mortise grooves. A plug with a diameter adapted to the hole is installed in the side through hole, and a magnetic ring is fixedly installed on the outside of the side through hole. A magnetic sheet is fixedly installed at the tail end of the plug. This utility model's tenon and mortise connection and separation structure allows for targeted shell replacement, effectively improving the actual utilization efficiency of the other shell, avoiding the waste of structural materials from uniform dismantling, effectively reducing actual maintenance and repair costs, lowering later usage costs, and improving practicality.

The application relates to the technical field of disc brake detection of electric vehicles, in particular to a use environment rapid simulation detection device applied to disc brakes of electric vehicles, which comprises a bottom-mounted detection box, a driving motor and a suction pump, and an arc-shaped detection chamber with an upper end opening is arranged in the bottom-mounted detection box. The use environment rapid simulation detection device applied to disc brakes of electric vehicles controls the introduction of a disc brake disc into the arc-shaped detection chamber through a disc type adjusting mode, cooperates with a disc brake caliper in the arc-shaped detection chamber, completes the detection operation in the interior, adopts a continuous detection mode, and greatly improves the detection efficiency; adopts a split type layout design, can detect the cooperation effect of different specifications of disc brake assemblies, thereby detects the optimal combination, and the detection range is more extensive; through the cavity detection mode, the influence of the external environment on the detection result can be avoided, the influence of the detection process on the external environment can be avoided, and the detection precision is guaranteed.
