Damping member, impact damping structure of electronic device, and electronic device

Abstract

The subject of the present invention is to provide a damping member capable of reliably absorbing impact even through the impact is strong or weak, an impact damping structure of an electronic device, and an electronic device. When a watch casing (1) is subjected to an outer weak impact corresponding to non elastic deformation of a first damping member (16), the impact is absorbed by volume change of a second damping member (17). In addition, when the watch casing (1) is subjected to an outer strong impact corresponding to elastic deformation of the first damping member (16), the strong impact is absorbed by the elastic deformation of the first damping member (16). It is possible to effectively damp outer impact to a watch core (4) within the watch casing (1), a driving electronic circuitportion (4a) of a display panel (13), and various required electronic members (4b) of a watch.

Description

technical field [0001] The present invention relates to electronic equipment used in watches, mobile phones, etc., a buffer member for absorbing external shocks, a shock buffer structure for electronic equipment, and electronic equipment. Background technique [0002] Conventionally, there is known a wristwatch having a shock-absorbing structure described in JP-A-2000-46964, in which a plurality of cushioning members are provided between a watch case and a watch movement housed in the watch. , the impact from the outside is buffered by the plurality of buffer parts to protect the watch movement. In the case of such a watch shock absorbing structure, each of the plurality of absorbing members is formed of an elastic material such as rubber. [0003] That is, the plurality of cushioning members is configured such that some of the cushioning members are annularly provided on the peripheral portion of the upper surface of the watch movement to elastically cushion impacts from t...

Problems solved by technology

[0004] However, in the case of the impact buffer structure of such a conventional watch, since a plurality of buffer members are respectively formed of elastic materials such as rubber, when the watch case receives an impact from the outside, because the structure is such that the impact passes through multiple The elastic deformation of the cushioning parts cushions with elastic force so that the impact is not directly transmitted to the watch movement. Therefore, there is a problem that the range of impact force that can be absorbed by the elastic force of multiple cushioning parts is limited.

[0005] That is, in such a shock-absorbing structure, when the shock is buffered, the elastic force corresponding to the buffer member buffers the shock, so when receiving a strong impact to the extent that the buffer member elastically deforms, the shock can be buffered by the buffer member. , but when receiving a weak shock to the extent that the cushioning part does not undergo elastic deformation, the shock cannot be absorbed by the cushioning part, and there is a problem that the shock is transmitted to the watch movement as it is.
