Lens cover with bistable membrane for spring effect

The invention relates to a lens cover with a bistable membrane for spring effect. A lens cover (100) for protecting a lens (200) having an optical portion (201) has: a base (101) having a spring film (102); a side wall (104) arranged to surround the optical portion (201) so as to form a cavity (110) between the base (101) and the optical portion (201), in which the spring membrane (102) is arranged to be movable between: a deformed position in which the spring membrane (102) is deformed towards the optical portion (201); and a rest position in which the spring membrane (102) extends away from the optical portion (201). 本申请涉及用于弹簧效应的具有双稳态膜的透镜盖。用于保护具有光学部分(201)的透镜(200)的透镜盖(100)具有：基部(101)，其具有弹簧膜(102)；侧壁(104)，其被布置成围绕所述光学部分(201)，以便在所述基部(101)和所述光学部分(201)之间形成腔(110)，其中所述弹簧膜(102)被布置成可在以下位置之间移动：变形位置，在该变形位置中所述弹簧膜(102)朝向所述光学部分(201)变形；以及静止位置，在该静止位置中所述弹簧膜(102)远离所述光学部分(201)延伸。
