The utility model provides an electromagnetic shielding flat door assembly, which comprises a door plate and a door frame. The door frame is surrounded by the peripheral edge of the door plate. The door plate is movably connected to the door frame through the door axle, and the peripheral edge surface of the door plate is provided with a clamp spring. When the door plate is closed, the clamp spring rests on the inner wall of the door frame, and the inner wall of the door frame is inclined and gradually enlarges along the closing direction of the door plate. The outer edge surface of the door panel is parallel to the inner wall of the door frame, so that the deformation direction of the clip spring is not perpendicular to the closing direction of the door panel. When the clamp spring of the electromagnetic shielding flat door assembly contacts the door frame, the reaction force produced by the door frame to the clamp spring will produce a component force along the deformation direction of the clamp spring, which is offset by the deformation force of the clamp spring, so as to reduce the pressure produced by the clamp spring on the door frame. In addition, the distance between the clamp spring and the door frame which causes relative sliding is also effectively reduced compared with the existing technology of electromagnetic shielding flat door assembly, thereby improving the service life of the electromagnetic shielding flat door assembly.

电磁屏蔽平开门组件
本技术涉及一种电磁屏蔽平开门组件。
技术介绍
现有技术中具有电磁屏蔽功能的平开门由门板、门框等部件组成,门框环绕于门板的周缘设置,而门板通过门轴与门框保持活动连接关系,以使其能够在开启和关闭状态之间切换。门板和门框表面均包覆着例如铜皮等金属材料,以用于在门板处于关闭状态时通过门板与门框表面的金属材料屏蔽电磁波。当该电磁屏蔽平开门组件的门板在处于关闭状态时,门板与门框之间的细小缝隙成为了电磁波的主要泄露通道。如图1所示,为提高该电磁屏蔽平开门组件1'的电磁屏蔽效果,通常会在门板2'的外周缘21'上设置金属卡簧4',并在关闭状态时通过该卡簧4'与门框3'的内壁面31'直接接触,使该金属材质的卡簧4'将门板2'与门框3'之间的缝隙封死。然而在门板2'开启或关闭的过程中,门板2'的外周缘21'表面与门框3'的内壁面31'之间平行地远离或靠近,导致卡簧4'在与门框3'的内壁面31'接触时,会在卡簧4'的接触表面上沿关门方向A产生巨大的摩擦力。该摩擦力的方向与卡簧4'的形变方向B垂直,因此无法通过卡簧4'的自身变形进行抵消。在长期使用过程中,该摩擦力不仅会导致卡簧4'的表面磨损并增加维修成本,还可能会使卡簧4'产生局部变形,从而无法有效阻挡电磁波从门板2'和门框3'之间的缝隙泄露,导致该电磁屏蔽平开门组件1'的电磁屏蔽能力下降。
