Abstract

An elastic apparatus and a terminal, comprising: a connecting part (10); a first elastic arm (21), wherein the first elastic arm (21) comprises a first front end (211), a first bending part (212) and a first rear end (213) that are connected in sequence, and the first rear end (213) is fixedly connected to the connecting part (10); a second elastic arm (22), wherein the second elastic arm (22) comprises a second front end (221), a second bending part (222) and a second rear part (223) that are connected in sequence, and the second rear end (223) is fixedly connected to the connecting part (10); and a third elastic arm (23), wherein the third elastic arm (23) comprises a third front end (231), a third bending part (232) and a third rear part (233) that are connected in sequence, and the third rear end (233) is connected to the connecting part (10). The first elastic arm (21), the second elastic arm (22) and the third elastic arm (23) are on a same side of the connecting part (10), the second front end (221) is located between the first front end (211) and the connecting part (10), and the third front end (231) is located between the second front end (221) and the connecting part (10).

Description

technical field [0001] The invention relates to mechanical technology, in particular to an elastic device and a terminal. Background technique [0002] Structural elastic devices generally include helical elastic devices and bent elastic devices. [0003] Wherein, the helical elastic device is such as a spring, and the bent elastic device is such as a shrapnel. [0004] Usually, the bending elastic device is a shrapnel that has been bent once, and the elastic force that can be provided is relatively small. In order to increase the elastic force, the prior art method is to thicken the elastic piece, or increase the volume of the elastic piece to provide greater elastic force. [0005] However, thickening the shrapnel is likely to cause plastic deformation of the shrapnel, and increasing the volume of the shrapnel will take up more space. Contents of the invention [0006] In view of this, the embodiments of the present invention provide an elastic device and a terminal, ...
