Title (EN) PROJECTION DEVICE
(FR) DISPOSITIF DE PROJECTION
(ZH) 投影装置
Abstract:
(EN) A projection device (100) comprises: a housing (110); an optical engine (120); a sensor switch (140); and a dust cap assembly (130). The optical engine (120) is disposed inside the housing (110) and is connected to the sensor switch (140). The optical engine (120) comprises a lens (122) embedded in one side surface of the housing (110). A sliding groove (150) is formed on an outer side of the side surface in which the lens (122) is embedded. The dust cap assembly (130) is slidably disposed in the sliding groove (150) and is configured to shield the lens (122). The sensor switch (140) is disposed on the side surface in which the lens (122) is embedded, and is configured to sense a location of the dust cap assembly (130) and to generate a switch control signal upon sensing a location variation of the dust cap assembly (130). The switch control signal is configured to control an operation state of the optical engine (120). The invention solves technical problems in which dust caps of existing projection devices tend to be lost easily and structures thereof are complex.
(FR) L'invention concerne un dispositif de projection (100) qui comprend : un boîtier (110) ; un moteur optique (120) ; un commutateur de capteur (140) ; et un ensemble capuchon anti-poussière (130). Le moteur optique (120) est disposé à l'intérieur du boîtier (110) et est connecté au commutateur de capteur (140). Le moteur optique (120) comprend une lentille (122) incorporée dans une surface latérale du boîtier (110). Une rainure de coulissement (150) est formée sur un côté externe de la surface latérale dans laquelle la lentille (122) est incorporée. L'ensemble capuchon anti-poussière (130) est disposé de manière coulissante dans la rainure de coulissement (150) et est configuré pour protéger la lentille (122). Le commutateur de capteur (140) est disposé sur la surface latérale dans laquelle la lentille (122) est incorporée, et est configuré pour détecter un emplacement de l'ensemble capuchon anti-poussière (130) et générer un signal de commande de commutateur lors de la détection d'une variation d'emplacement de l'ensemble capuchon anti-poussière (130). Le signal de commande de commutateur est configuré pour commander un état de fonctionnement du moteur optique (120). L'invention résout les problèmes techniques dans lesquels des capuchons anti-poussière de dispositifs de projection existants ont tendance à être facilement perdus et leurs structures sont complexes.
(ZH) 一种投影装置(100),包括:机壳(110)、光机(120)、感应器开关(140)及防尘盖组件(130)。所述光机(120)设置于所述机壳(110)内,所述光机(120)与所述感应器开关(140)连接,所述光机(120)包括一个光机镜头(122),所述光机镜头(122)内嵌于所述机壳(110)的一个侧面内。在所述光机镜头(122)内嵌的侧面外侧上设置有滑槽(150),所述防尘盖组件(130)滑动的设置于所述滑槽(150)内。所述防尘盖组件(130)用于遮挡所述光机镜头(122)。所述感应器开关(140)设置于所述光机镜头(122)内嵌的侧面上,所述感应器开关(140)用于感应所述防尘盖组件(130)的位置并在感应到所述防尘盖组件(130)位置变化时产生开关控制信号,所述开关控制信号用于控制所述光机(120)的工作状态。解决了现有技术中投影装置防尘盖存在的易丢失、结构复杂等技术问题。
