具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
投影仪是一种能够投射出影像画面的设备，一种投影仪可以包括光源组件、光阀组件以及投影镜头等结构。其中，光源组件可以用于向光阀组件提供光源，光阀组件用于基于光源组件提供的光源生成影像光束，投影镜头可以用于对光阀组件生成的影像光束进行处理以及调整，并将经过处理以及调整后的影像光束射出投影仪，例如，可以投射至投影幕布上，以在投影幕布上呈现出影像画面。
图1是相关技术中一种投影仪的结构示意图，该投影仪中可以包括光源组件01以及投影镜头02等结构。图2是图1所示的投影仪中的光源组件的立体结构示意图，图3是 图2所示的光源组件中的激光器以及激光器电路板的一种立体结构示意图，图4是图2所示的光源组件的结构框图。请参考图1、图2、图3以及图4。其中，该光源组件01包括光源壳体11、激光器12、激光器电路板13以及连接引线14，激光器12安装于激光器电路板13上，且激光器12与激光器电路板13电连接，激光器电路板13安装于光源壳体11上，连接引线14的一端与激光器电路板13电连接，连接引线14的另一端与电源组件15电连接，电源组件15可以为激光器电路板13上的激光器12供电。另外，由于激光器电路板13的尺寸通常较大，为了降低激光器电路板13与光源壳体11之间的振动发出的声音，该光源组件还可以包括位于激光器电路板13和光源壳体11之间的消音泡棉16。
但是，上述光源组件中，激光器安装于激光器电路板上，并与激光器电路板上的走线连接，激光器电路板上的走线还与连接引线的一端连接，该连接引线的另一端与电源组件连接，对应的，电源组件提供的电流会依次经过连接线、连接线与激光器电路板之间的连接点、激光器电路板上的导电线路以及激光器电路板上的导电线路和激光器之间的连接点，再流入激光器中，因此光源组件的结构较复杂。
在该复杂的结构下，光源组件的安装过程也会较为繁琐，示例性的，将激光器安装于激光器电路板上，目前通过焊接的方式将激光器焊接于激光器电路板上，之后再将激光器电路板通过螺钉固定于光源壳体上。整个安装过程较为繁琐，耗时较长，导致光源壳体的制造效率较低。
另外，为了保证激光器电路板的结构强度，且在激光器电路板上需要设置与激光器以及各种连接线的连接点，使得光源组件中激光器电路板(激光器电路板可以为印制电路板(Printed Circuit Board，PCB))的尺寸较大，这一方面会导致光源壳体的整体体积较大，另一方面需要在光源壳体上设置对应的尺寸较大的安装结构(如定位柱等结构)，用以安装激光器电路板。这大大限制了光源壳体的大小，不利于光源壳体的小型化，且会限制激光器在光源壳体上的位置。示例性的，请参考图2，尺寸较大激光器电路板13会导致光源壳体11在区域q1处的尺寸较大，阻碍了光源壳体的小型化。
本申请实施例提供了一种光源组件以及投影仪，能够简化激光器的供电驱动结构，从而简化光源组件的结构，利于光源组件的小型化。
图5是本申请实施例提供的一种光源组件的结构示意图，图6是图5所示的光源组件中激光器的结构示意图，图7是图5所示的光源组件中连接端子的结构示意图。请参考图5、图6以及图7，其中，光源组件包括光源壳体31、激光器32、以及连接端子33。
激光器32包括激光器本体321以及激光器引脚322，激光器引脚322位于激光器本体321上，且激光器引脚322与激光器本体321电连接。
激光器本体321与光源壳体31固定连接，连接端子33与激光器本体321上的激光器引脚322电连接，且所述连接端子33还被配置为与电源组件(图3和图4中未示出)电 连接。
综上所述，本申请实施例提供的一种光源组件，通过将激光器本体与光源壳体固定连接，并通过连接端子来将电源组件与激光器本体电连接，由连接端子实现了相关技术中激光器电路板的电连接功能，如此便无需在光源壳体中设置激光器电路板，解决了相关技术中光源组件的结构较为复杂的问题，实现了简化光源组件的结构的效果。
另外，由于该光源组件中不包括激光器电路板，节省了将激光器安装于激光器电路板上的过程，进而便实现了提升光源壳体的生产效率的效果。且由于激光器电路板的体积通常较大，进而同样实现了缩小光源组件的体积的效果，有利于光源组件的小型化。并且通过连接端子电连接的方式，还可以避免相关技术中使用驱动电路板时的噪音问题。
图8是本申请实施例提供的另一种光源组件的结构示意图，图9是图8所示的光源组件的爆炸结构示意图，图10是图8所示的光源组件中连接端子以及激光器的结构示意图。该光源组件在图5所示的结构的基础上进行了一些调整。请参考图8、图9以及图10，其中，连接端子33包括第一连接头331以及第一连接引线332，第一连接头331与激光器引脚322电连接，第一连接引线332的一端与第一连接头331电连接，另一端被配置为与电源组件电连接。
在一种示例性的实施例中，第一连接头331与光源壳体31固定连接。也即是在图5所示的光源组件的基础上，将第一连接头331也与光源壳体31进行固定连接。如此可以进一步提升第一连接头331的稳固程度，提升光源组件的稳定性。
图5所示的光源组件中，激光器与光源壳体固定连接，第一连接头通过引脚与激光器实现了连接，并基于该连接，实现了固定于光源壳体上的效果。而图8、图9以及图10所示的光源组件中，进一步将第一连接头331也与光源壳体31进行固定连接，以提升第一连接头331与光源壳体31之间连接的稳固程度。
在本申请实施例提供的光源组件中，第一连接头331也与光源壳体31之间可以通过多种方式实现固定连接，在一种示例性的实施例中，第一连接头331包括插接结构331a、连接片331b，连接片331b与插接结构331a连接。其中，连接片331b通过锁固件与光源壳体连接固定。在一具体实施中，锁固件为第一螺钉331c。其中，连接片和第一螺钉的数量对应，可以为多个。
插接结构331a与激光器本体321上的激光器引脚电连接，且第一连接引线332的另一端与插接结构331a电连接。
具体地，连接片331b上具有第一开孔k1，光源壳体31上具有第一螺孔s1，第一螺钉331c穿过连接片331b上的第一开孔k1，并与光源壳体31上的第一螺孔s1螺纹连接，以将连接片331b固定在光源壳体31上。在此基础上，由于连接片331b与插接结构331a连接，进而便可以将插接结构同样固定在光源壳体31上。其中，插接结构可以包括插口， 激光器的引脚可以插入该插口中，以与插接结构电连接。
此种结构下，第一连接头331可以通过螺钉实现与光源壳体31的固定连接，当然，该第一连接头331还可以通过其他方式实现与光源壳体31的固定连接，本申请实施例对此不进行限制。
上述实施例提供了一种第一连接头与激光器引脚的连接结构，此种连接结构中，激光器引脚与第一连接头插接，但激光器引脚与第一连接头还可以通过其他结构实现连接，如搭接等，本申请实施例对此不进行限制。
图11是本申请实施例提供的光源组件中一种连接端子的结构示意图，请参考图11。其中，第一连接头331中的连接片331b与插接结构331a为一体件。连接片的数量为偶数个，且在插接结构的两侧相对设置。在一具体实施中，连接片331b的数量为2，两个连接片331b在插接结构331a的两侧。
以及，在本申请多个示例中，激光器具有多组引脚，分别位于激光器本体相对的两侧。激光器引脚的组数为偶数个，从而激光器引脚的个数也为偶数个。
为简便示例，请参考图4，激光器中激光器引脚322的组数为2，两组激光器引脚322分别位于激光器本体相对的两侧；其中，每组激光器引脚322可以包括两个引脚。
第一连接头331的数量为2，两个第一连接头331分别与两组引脚电连接。
请参考图11，第一连接引线332的组数为2，两组第一连接引线332的一端分别与两个第一连接头331电连接。示例性的，每组第一连接引线332可以具有两根连接线。
在一种示例性的实施例中，光源组件还包括第二连接头35，两组第一连接引线332的另一端分别与第二连接头35电连接，第二连接头35被配置为与电源组件电连接。该第二连接头可以为用于与电源组件连接的一个接头，该接头的规格可以与电源组件上用于与光源组件供电的接口匹配，以便于与第二连接头电连接。
请参考图9，对于每个第一连接头331，第一螺钉331c的数量对应的为2，两个第一螺钉331c分别穿过两个连接片331b上的第一开孔k1，并与光源壳体31上的第一螺孔s1螺纹连接。该第一螺孔s1的规格与第一螺钉331c的规格相匹配。
在一种示例性的实施例中，还包括第二螺钉323，光源壳体31上还具有第二螺孔s2。该第二螺孔s2的规格与第二螺钉323的规格相匹配。
激光器本体321的边缘具有缺口k3，第二螺钉323位于缺口k3处，且与光源壳体31上的第二螺孔s2螺纹连接。如此结构下，第二螺钉323可以通过该缺口k3来将激光器本体321固定于光源壳体31上，该通过缺口k3的固定方式，可以降低第二螺钉323与激光器本体321的连接区域在激光器本体321上占用的空间，进而可以便于缩小激光器本体321的尺寸，有利于光源组件以及投影仪的小型化。当然，在本申请实施例提供的光源组件中，激光器还可以通过其他方式来与光源壳体来实现固定连接，示例性的，激光器还可以通过 粘结、卡接、焊接中的至少一种方式来与光源壳体来实现固定连接，本申请实施例对此不进行限制。
在一种示例性的实施例中，激光器本体的边缘具有第二开孔，第二螺钉穿过第二开孔，且与光源壳体上的第二螺孔螺纹连接。也即是激光器也可以通过螺钉穿过开孔并与光源壳体上的螺孔连接的方式，来将激光器固定于光源壳体上。
在一示例中，光源组件可以包括多组激光器，每组激光器的数量为1个，这多组激光器发出相同颜色的激光，且这多组激光器并联。在具体实施中，每一组激光器分布配置有一组连接端子，每组连接端子包括一个连接端子。
以及，在另一实施中，多组激光器发出不同颜色的激光，比如包括3组激光器，分别发出蓝色激光，绿色激光和红色激光，每一组激光器发出的颜色均与其他组激光器不同。以及，每一组激光器分别配置有一个连接端子。
图12是本申请实施例提供的另一种光源组件的拆解结构示意图，请参考图12，可以看出，由于在光源组件中无需设置激光器电路板，使得光源壳体上可以空出一些区域，示例性的，与图2所示的光源组件相比，图12所示的光源组件中，区域q2由于未被激光器电路板占用，进而可以将此部分的光源壳体31进行缩减，以缩小光源壳体31的整体尺寸，以便于实现投影仪的小型化。
在一种示例性的实施例中，光源组件还包括密封结构，密封结构位于激光器本体以及光源壳体之间，且与激光器本体以及光源壳体抵接。该密封结构可以在激光器本体以及光源壳体的压力的作用下，实现激光器本体与光源壳体之间的密封，以提升光源壳体内部的运行环境的稳定，避免受到外界环境的干扰。
在一种示例性的实施例中，光源组件中可以包括一个激光器或多个激光器。其中，每个激光器的引脚个数为偶数个，分别对称排布在激光器本体的两侧。其中这些偶数个引脚中，设置有一个正极引脚，其他为负极引脚。
具体地，请参考图13，图13是本申请实施例提供的光源组件中另一种激光器以及连接端子的结构示意图，该图13中示出了激光器中的多个激光单元u。该图可以是图10所示的结构在另一侧的结构示意图，由图13可以看出多个激光单元u在激光器本体中排成了两行。
图14是本申请实施例提供的光源组件中一种激光器的结构示意图，其中，激光器本体321包括基板3211以及位于基板3211上阵列排布的多个激光单元(芯片)。这多个激光单元可以包括用于发出红色激光光束的红光激光单元u3，用于发出绿色激光光束的绿光激光单元u2，以及用于发出蓝色激光光束的蓝光激光单元u1。这些激光单元在基板3211上排成两行，一行包括7颗红色激光单元，另一行包括3颗蓝色激光单元以及4颗绿色激光单元。当然，本申请实施例提供的光源组件中，激光器还可以为其他结构，本申请实施例 对此并不进行限制。
激光器引脚322可以包括第一导电引脚t1、第二导电引脚t2、第三导电引脚t3以及第四导电引脚t4。其中，第一导电引脚t1可以为正极引脚，第二导电引脚t2、第三导电引脚t3以及第四导电引脚t4可以为负极引脚，或者，第一导电引脚t1可以为负极引脚，第二导电引脚t2、第三导电引脚t3以及第四导电引脚t4可以为正极引脚。第一导电引脚t1可以同时与串联的多个红光激光单元u3的第一端、串联的多个绿光激光单元u2的第一端和串联的多个蓝光激光单元u1的第一端连接；第二导电引脚t2、第三导电引脚t3以及第四导电引脚t4可以分别与串联的多个红光激光单元u3的第二端、串联的多个绿光激光单元u2的第二端和串联的多个蓝光激光单元u1的第二端连接。
当第一导电引脚t1为正极引脚，第二导电引脚t2、第三导电引脚t3以及第四导电引脚t4为负极引脚时，串联的多个红光激光单元u3、串联的多个绿光激光单元u2和串联的多个蓝光激光单元u1共用一个正极引脚。当第一导电引脚t1为负极引脚，第二导电引脚t2、第三导电引脚t3以及第四导电引脚t4为正极引脚时，串联的多个红光激光单元u3、串联的多个绿光激光单元u2和串联的多个蓝光激光单元u1共用一个负极引脚。如此结构下，激光器通过共用正极引脚或者负极引脚，简化了激光器的封装工艺，降低了激光器的制造成本。
第一导电引脚t1、第二导电引脚t2、第三导电引脚t3以及第四导电引脚t4的一端与各个激光单元连接，另一端向外伸出，用于和第一连接头连接。
综上所述，本申请实施例提供的一种光源组件，通过将激光器本体与光源壳体固定连接，并通过连接端子来将电源组件与激光器本体电连接，由连接端子实现了相关技术中激光器电路板的电连接功能，如此便无需在光源壳体中设置激光器电路板，解决了相关技术中光源组件的结构较为复杂的问题，实现了简化光源组件的结构的效果。
另外，由于该光源组件中不包括激光器电路板，节省了将激光器安装于激光器电路板上的过程，进而便实现了提升光源壳体的生产效率的效果。且由于激光器电路板的体积通常较大，进而同样实现了缩小光源组件的体积的效果，有利于光源组件的小型化。并且通过连接端子电连接的方式，还可以避免相关技术中使用驱动电路板时的噪音问题。
图15是本申请实施例提供的一种投影仪的内部结构示意图，该投影仪包括控制电路10(仅在图15中示出部分控制电路)，光机40，投影镜头30以及光源组件20。光源组件20用于在控制电路10的控制下发出照明光束，并将照明光束入射光机40进行调制，调制后的光束进入投影镜头30成像。其中，投影仪还包括电源组件(图中未示出)，电源组件可以是电路板，电路板上通常设置有变压器元件，用于输出各光学部件和电学部件所需的供电电压，以及，电源组件也可以是适配器，在微型投影仪中，可以通过适配器和转接板的方式提供电源信号输出，此时，投影仪的各待供电部件可以和转接板连接，实现与适配 器的间接连接。
图16是本申请实施例提供的光源组件中连接端子以及激光器的结构示意图。参见图16，激光器本体321两侧各设置有4根引脚，对应地，连接端子33包括第一连接头331以及第一连接引线332，第一连接头331与激光器引脚322电连接，第一连接引线332的一端与第一连接头331电连接，另一端被配置为与电源组件电连接。具体地，每一侧的第一连接引线332对应每一侧的4根引脚也设置有4根。第二连接头35上共连接有8根第一连接引线。
图17A和图17B是本申请实施例提供的另一种激光器与连接端子、电源组件的连接结构的正反两个面的示意图。其中图17A为激光器与连接端子、电源组件的正面连接示意图，如图17A所示，激光器本体321与第一连接头331插接连接，通过第一连接引线332连接至电源组件37。在本示例中，电源组件37可以为投影设备中的电源板，电源板为整个系统提供供电，电源板上外接交流电，并通过电压转换为投影设备提供低压直流供电。也可以是连接适配器的电路转接板，适配器进行电压转换，电路转接板提供一个转接接口。参见图17B所示，为激光器、连接端子与电源组件连接的反面结构示意图。其中，激光器本体321通过第一连接头331，第一连接引线332，并最终通过第二连接头35插接连接到电源组件37上。
图18A和图18B是本申请实施例提供的再一种激光器与连接端子、电源组件的连接结构示意图，对应第，图18A和图18B为上述连接结构的正反两个视图。
与图17A和图17B的示例不同的是，本示例中，连接至第二连接头35的第一连接引脚332的数量可以小于激光器本体321上的激光器引脚总数。如图19示例的一种激光器内部引脚电连接结构示意图。参见图19，激光器本体两侧具有4组共8根引脚，其中每组引脚对应一组正负极。激光器本体内部的发光芯片具有多个，当按照行列规则排列时，每一行发光芯片对应一组正负极的引脚，比如图示中具有四行发光芯片，在一种示例中，当这些发光芯片均发出相同颜色激光，则可以同时驱动发光，则这四行发光芯片的每一行的正负极可视为具有能够首尾相连的串联关系。这种情形下，一种实施方式中为了结构简便，可以如图17A和图17B中所示，每一行芯片的正负极分别对应一根连接引线，这样每一组正负极需要连接两根连接引线。在另一实施方式中，也可以将上一行的负极和下一行的正极直接连接，而不经过第二连接头。如图18A和图18B和图19所示，可以将第三行的负极和第四行的正极连接，这样可以减少两根连接至第二连接头35的第二连接引线，从而可以简化第二连接头35的结构。
以及，在一实施方式中，仍可参见图19，当第一行发光芯片和第二行发光芯片发出的不同颜色的激光，第三行发光芯片和第四行发光芯片发出相同颜色的激光且与第一发光芯片、第二行发光芯片发出的激光颜色均不相同的情况下，就可以如图18A和图18B所示， 第一行引脚1和第二行的引脚2的正负极各连接一组连接引线，而第三行引脚3的负极和第四行引脚4的正极先进行串联，第三行引脚3的正极和第四行引脚4的负极再分别连接一根连接引线，并最终连接到第二连接头上。
需要说明的是，为了简便说明原理，图18A和图18B所示例中有一组引脚进行了正负极的串联。本申请实施例并不限定进行串联的正负极引脚的组数。
综上所述，本申请实施例提供的投影仪，通过将激光器本体与光源壳体固定连接，并通过连接端子来将电源组件与激光器本体电连接，由连接端子实现了相关技术中激光器电路板的电连接功能，如此便无需在光源壳体中设置激光器电路板，解决了相关技术中光源组件的结构较为复杂的问题，实现了简化光源组件以及投影仪的结构的效果。
另外，由于该光源组件中不包括激光器电路板，节省了将激光器安装于激光器电路板上的过程，进而便实现了提升光源壳体的生产效率的效果。且由于激光器电路板的体积通常较大，进而同样实现了缩小光源组件的体积的效果，有利于光源组件以及投影仪的小型化。并且通过连接端子电连接的方式，还可以避免相关技术中使用驱动电路板时的噪音问题。
如图20所示，图20是本申请实施例还提供一种光源组件的组装方法的方法流程图，该方法可以用于组装上述实施例提供的任一光源组件，该光源组件的组装方法可以包括下面几个步骤：
步骤2001、将第一连接头与激光器进行连接。
可以参考图10，第一连接头331的数量可以为2，两个第一连接头331分别在激光器22的两侧，与位于激光器22两侧的激光器引脚插接，以实现第一连接头331与激光器22之间的电连接。请参考图11，其中，第一连接引线332的组数为2，两组第一连接引线332的一端分别与两个第一连接头331电连接。示例性的，每组第一连接引线332可以具有两根连接线。在一种示例性的实施例中，光源组件还包括第二连接头35，两组第一连接引线332的另一端分别与第二连接头35电连接，第二连接头35被配置为与电源组件电连接。该第二连接头可以为用于与电源组件连接的一个接头，该接头的规格可以与电源组件上用于与光源组件供电的接口匹配，以便于与第二连接头电连接。
步骤2002、将连接的第一连接头以及激光器固定于光源壳体上。
本步骤可以包括将第一连接头固定于光源壳体，以及将激光器固定于光源壳体上两个部分，其中，将第一连接头固定于光源壳体的方式可以参考图9，对于每个第一连接头331，第一螺钉331c的数量对应的为2，可以使两个第一螺钉331c分别穿过两个连接片331b上的第一开孔k1，并与光源壳体31上的第一螺孔s1螺纹连接，以将连接片331b固定在光源壳体31上。在此基础上，由于连接片331b与插接结构331a连接，进而便可以将插接结构同样固定在光源壳体31上。其中，插接结构可以包括插口，激光器的引脚可以插入该 插口中，以与插接结构电连接。
此种结构下，第一连接头331可以通过螺钉实现与光源壳体31的固定连接，当然，该第一连接头331还可以通过其他方式实现与光源壳体31的固定连接，本申请实施例对此不进行限制。
激光器固定于光源壳体上的方式可以继续参考图9，其中，激光器本体321的边缘具有缺口k3，可以将第二螺钉323设置于该缺口k3处，且与光源壳体31上的第二螺孔s2螺纹连接。如此结构下，第二螺钉323可以通过该缺口k3来将激光器本体321固定于光源壳体31上，该通过缺口k3的固定方式，可以降低第二螺钉323与激光器本体321的连接区域在激光器本体321上占用的空间，进而可以便于缩小激光器本体321的尺寸，有利于光源组件以及投影仪的小型化。当然，在本申请实施例提供的光源组件中，激光器还可以通过其他方式来与光源壳体来实现固定连接，本申请实施例对此不进行限制。
步骤2003、将与第一连接头连接的第一连接线与电源组件电连接。
在一种示例性的实施例中，请参考图11，该光源组件还包括第二连接头35，两组第一连接引线332的另一端分别与第二连接头35电连接，该第二连接头可以为用于与电源组件连接的一个接头，该接头的规格可以与电源组件上用于与光源组件供电的接口匹配，以便于与第二连接头电连接。
在将与第一连接头连接的第一连接线与电源组件电连接时，可以将第二连接头36与电源组件电连接。
当然，步骤2003也可以在步骤2001之前执行，也即是可以先将第一连接头与电源组件电连接，再将第一连接头与激光器插接，本申请实施例对此不进行限制。
综上所述，本申请实施例提供的光源组件的组装方式，通过将第一连接头与激光器进行连接，并将连接的第一连接头以及激光器固定于光源壳体上，如此便节省了将激光器安装于激光器电路板上的过程，解决了相关技术中光源壳体的组装过程较为繁琐，组装效率较低的问题，实现了提升光源壳体的组装效率的效果。
以上所述仅为本申请的可选实施例，并不用以限制本申请，凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
