Description

切换式电波暗室
技术领域
本发明涉及一种电波暗室,特别是用于测试手机辐射的切换式电波暗室。
背景技术
手机、电脑等电子产品在开发过程中均需要利用电波暗室进行各种不同的辐射测试,常用的电波暗室分为全电波式及半电波式,不同辐射测试需要在两者之间更换,如此,在对手机做不同测试时,需要人工在全电波暗室及半电波暗室之间更换测试设备及手机,因此需增加设备、人力、时间造成产品成本高,而且还影响测试稳定性。
发明内容
鉴于以上内容,有必要提供一种测试稳定且成本较低的可切换式电波暗室。
一种切换式电波暗室,其包括底座及罩于底座上的罩体、数个切换面板及驱动部,数个切换面板形成有反射面及与反射面相反的吸波面,该驱动部包括主动轴、与切换面板对应的随动轴及数个传送带,主动轴与随动轴旋转装于底座,每一传送带将一随动轴与主动轴连接,该切换面板可转动地装于底座上并与随动轴固定连接,主动轴旋带动传送带转动时,传送带带动数个随动轴同时转动,所述数个随动轴进而带动数个切换面板同时翻转,切换反射面与吸波面,实现全电波式电波暗室及半电波式全电波式间的切换。
本发明切换式电波暗室转换面板设有反射面及吸波面,通过驱动部带动电波暗室旋转度实现该反射面与吸波面的转换,进而实现电波暗室的全电波式与半电波式切换,即在一个电波暗室内实现不同测试,节省工时,保证测试的稳定性。

具体实施方式
请参阅图1及图2,本发明较佳实施方式切换式电波暗室100为一箱体,用于容置天线40对手机(图未示)进行辐射测试,其包括底座10、盖于底座10的涂有吸波材料的矩形罩体101,承载台15、数个转换面板20及驱动部30(如图3所示)。该底座10为盒体,其包括底壁11、与底壁11相对设置的顶壁12及设于顶壁12与底壁11之间支撑顶壁12的侧壁13(图未标)。该顶壁12、底壁11及侧壁13围成容置腔14。该顶壁12设有一背向底壁11方向的表面121及开设于顶壁12中部的与容置腔14贯通的通槽122。该表面121上通槽122的周缘涂有吸波层板。该天线40及承载台15装设于该表面121上并位于该通槽122的两侧。该承载台15用于放置待测手机。
本实施例中,该转换面板20设有三个,均为长方形板体,每一转换面板20一侧装有一反射平板21,如不锈钢板;与该反射平板21相对的另一侧装有一吸波层22,本实施例为吸波泡棉层。该三个转换面板20可并列装设于该顶壁12的通槽122内,该反射平板21及吸波层22于竖直方向凸出通槽122。
如图3所示,该驱动部30包括马达31、主动轴32、三个随动轴33及连接主动轴32与三个随动轴33的三个传送带34。该马达31装于容置腔14内的底壁11上,该主动轴32可转动连接马达31于一侧壁13上并靠近底壁11。该主动轴32上间隔装有三个传送轮321。该三个随动轴33平行间隔可转动装设于设有主动轴32的侧壁13上,且靠近顶壁12。本实施例中,该主动轴32与三个随动轴33通过轴承连接实现相对侧壁13的转动。每个随动轴33上套设有随动轮331。每一传送带34分别安装于一传送轮321与一相对应的随动轮331上,并且安装后的三个传动带34互不干涉,且通过传送带34的传动,每一传送轮321的转动能带动随动轮331作相应的转动。
请复参图1,每一切换面板20一端分别固定于随动轴33的端部,每一切换面板20的另一端通过转轴(图未示)可旋转地装设于另一侧壁13上。因此,当三个反射平板21共面,形成一反射面25并凸出该通槽122,三个吸波层22位于同一平面上形成一吸波面26并凸出该表面121,由于表面121及罩体101内测涂有吸波材料,此时,该吸波面26与表面121及罩体101围成一箱体,即全电波式电波暗室。
当需要切换电波暗室100从全电波式暗室至半电波式电波暗室时,该马达31带动主动轴32转动,该传送轮321带动传送带34运动,传送带34拉动随动轮331转动,进而带动三个随动轴33同时旋转,三个转换面板20分别随随动轴33翻转180度为止,即将反射面25露出表面121上,此时,反射面25与罩体101形成半电波式电波暗室。
该切换式电波暗室100转换面板20设有反射面25及吸波面26,通过驱动部30带动转换面板20旋转180度实现该反射面25与吸波面26的转换,进而实现电波暗室100的全电波式与半电波式切换。无需搬运待测试手机,更换不同的电波暗室,节省工时,而且保证测试稳定性。
