Mobile terminal and falling protection method thereof
ActiveCN107094194AReduce impact stressGood cushioning effectDigital data processing detailsDevices with sensorFall protectionImpact stress
The invention discloses a mobile terminal and a falling protection method thereof and belongs to the technical field of mobile communication. The mobile terminal comprises a display panel, a middle frame, a rear shell, a protection module and a detection module. The middle frame is mounted in the rear shell. The display panel is arranged on the middle frame. The protection module comprises a buffering popup block and a popup block control unit. The buffering popup block is mounted on the middle frame. The popup block control unit is used for controlling the buffering popup block to be popped up when the detection module detects falling of the mobile terminal. At the moment when the mobile terminal falls to the ground, the buffering popup block absorbs the impulse generated in the falling process of the mobile terminal, the instantaneous impact stress of the mobile terminal is reduced, so a module is protected, and a stress concentrated phenomenon is avoided. The buffering popup block is arranged on the middle frame, so the mobile terminal can be protected well, and the problems such as screen breakage and internal module damage resulting from the falling of the mobile terminal can be avoided.

Multiple punch and die assembly providing hand disassembly, punch length adjustment and replacement
ActiveUS7726554B2Eliminate scoring and marking of sheet materialReduce impact stressDigitally marking record carriersPerforating toolsStress boneEngineering
A multiple punch and multiple die assembly has a workpiece protector which is a punch lifter that is operatively associated with each punch for supporting each of the punches in an inactive position as an active punch is moved by the ram to the active, i.e. operating position to thereby eliminate scoring or marking of the sheet material or other workpiece that is being punched. To eliminate the need for hand tools and hand assembly or disassembly, a manually moveable retainer on the punch assembly is provided that can be moved by hand between a punch-releasing and punch-retaining position for holding the punches within the multi-punch assembly during operation. To prevent stress fractures that formerly occurred in die carriers, support of each die is distributed between two different die components thereby reducing impact stress on the carrier as the ram drives the punch through the workpiece.

A diverter valve includes a valve bore having a set of valve seats associated with each fluid outlet port. Each set of valve seats is at least partially separated from one another by a flow channel. The valve seat configuration increases the impact area for the valve element. As a result, the impact force upon seating against the valve seats is reduced. Moreover, by including flow channels between the sets of valve seats, the switching force and performance of the valve element is not adversely affected.
