具体实施方式detailed description
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。The technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present invention.
参见图1至图4，本实施例一种风道组件，包括竖向设置的风道骨架100、竖向设置的导板200和驱动机构300，风道骨架100上设有出风口110，与空调室内机前面板上的出风口对应，驱动机构300用于驱动导板200转动以开闭风道骨架出风口，从而使其出风口与空调室内机前面板上的出风口相通；导板200包括面板部210和位于面板部210两端处的连接部220，驱动机构300为两套，分别安装在风道骨架100的两端部上，以平稳驱动导板200转动；与现有技术不同的是，本实施例中驱动机构300包括电机310、小齿轮320和大齿轮330，电机310、小齿轮320和大齿轮330的转动轴线均为竖向轴线，电机310同现有技术采用偏心电机，小齿轮320与电机310的输出轴传动连接，且小齿轮320与大齿轮330啮合，大齿轮330和与其处于同一端的连接部220传动连接。Referring to FIGS. 1 to 4, this embodiment of an air duct assembly includes an air duct skeleton 100 disposed vertically, a guide plate 200 disposed vertically, and a driving mechanism 300. The air duct skeleton 100 is provided with an air outlet 110 and an air conditioner. Corresponding to the air outlet on the front panel of the indoor unit, the driving mechanism 300 is used to drive the guide plate 200 to rotate to open and close the air duct skeleton air outlet, so that the air outlet communicates with the air outlet on the front panel of the air-conditioning indoor unit; the guide panel 200 includes a panel portion 210 and the connecting part 220 at both ends of the panel part 210, the driving mechanism 300 is two sets, which are respectively installed on both ends of the air duct frame 100 to smoothly drive the guide plate 200 to rotate; unlike the prior art, this In the embodiment, the driving mechanism 300 includes a motor 310, a pinion 320, and a large gear 330. The rotation axes of the motor 310, the pinion 320, and the large gear 330 are all vertical axes. The motor 310 uses the eccentric motor and the pinion 320 as in the prior art. It is drivingly connected to the output shaft of the motor 310, and the small gear 320 meshes with the large gear 330, and the large gear 330 is drivingly connected to the connecting portion 220 at the same end thereof.
驱动机构300的工作原理是，电机310工作，带动小齿轮320同步转动，进而带动大齿轮330转动，大齿轮330通过导板200的连接部220带动整个导板200转动，以开闭出风口110。由于小齿轮320和大齿轮330始终处于啮合状态，若电机310停止工作，仅掰动导板200，无法使小齿轮320和大齿轮330转动，进而无法使导板200转动打开，减少安全隐患，提高了使用安全性。The working principle of the driving mechanism 300 is that the motor 310 works to drive the pinion gear 320 to rotate synchronously, and then drive the large gear 330 to rotate. The large gear 330 drives the entire guide plate 200 to rotate through the connection portion 220 of the guide plate 200 to open and close the air outlet 110. Since the small gear 320 and the large gear 330 are always in the meshing state, if the motor 310 stops working, only the guide plate 200 is moved, and the small gear 320 and the large gear 330 cannot be rotated, so that the guide plate 200 cannot be rotated and opened, which reduces potential safety hazards and improves Use security.
进一步地，如图2至图4所示，驱动机构300还包括固定安装在风道骨架100的端部上的电机座340，电机座340包括顶板341和位于顶板341底面上并贯穿顶板341的小齿轮容置腔342，电机310固设在顶板341上，小齿轮320安装在小齿轮容置腔342内。这样电机310、电机座340和小齿轮320可构成一个整体模块，从而便于模块化安装，提高安装效率和安装精度。Further, as shown in FIGS. 2 to 4, the driving mechanism 300 further includes a motor base 340 fixedly mounted on the end of the air duct skeleton 100. The motor base 340 includes a top plate 341 and a bottom plate 341 that penetrates the top plate 341. The pinion gear accommodation cavity 342, the motor 310 is fixed on the top plate 341, and the pinion gear 320 is installed in the pinion gear accommodation cavity 342. In this way, the motor 310, the motor base 340 and the pinion gear 320 can form an integrated module, thereby facilitating modular installation and improving installation efficiency and installation accuracy.
进一步地，对于电机座340在风道骨架100端部上的安装，具体地，在其顶板341的底面上还固设有多个定位柱343，多个定位柱343用于将电机座340固设在风道骨架100的端部上，如图2至图4所示，其中部分定位柱343的自由端上具有卡扣3431，相应地风道骨架100的端部上具有相适配的 卡扣部120，此部分定位柱343与风道骨架100的端部卡扣连接，剩余定位柱343与风道骨架100的端部螺钉连接。本实施例中，定位柱343数量为3个，形成三角分布，以提高电机座340的安装稳固性，其中两个定位柱343通过上述卡扣结构连接在风道骨架100的端部上，另一定位柱343通过螺钉固设在风道骨架100的端部上，从而在保证电机座340安装可靠性的基础上，提高安装效率。Further, for the installation of the motor base 340 on the end of the air duct skeleton 100, specifically, a plurality of positioning posts 343 are further fixed on the bottom surface of the top plate 341, and the plurality of positioning posts 343 are used to fix the motor base 340 Set on the end of the air duct skeleton 100, as shown in FIGS. 2 to 4, part of the positioning post 343 has a buckle 3431 on the free end, correspondingly there is a matching card on the end of the air duct skeleton 100 In the buckle portion 120, this part of the positioning post 343 is snap connected to the end of the air duct skeleton 100, and the remaining positioning post 343 is screwed to the end of the air duct skeleton 100. In this embodiment, the number of positioning posts 343 is three, forming a triangular distribution to improve the installation stability of the motor base 340. Among them, two positioning posts 343 are connected to the end of the air duct frame 100 through the above-mentioned snap structure, and A positioning post 343 is fixed on the end of the air duct skeleton 100 by screws, thereby improving the installation efficiency on the basis of ensuring the installation reliability of the motor base 340.
对于大齿轮330在风道骨架100的端部上的安装，具体地，在风道骨架100上设有大齿轮支撑套筒130，大齿轮330包括中心轴331和齿轮部332，中心轴331具有位于齿轮部332下方的阶梯轴部333，阶梯轴部333插设在大齿轮支撑套筒130内并支撑在大齿轮支撑套筒130上，大齿轮330通过其阶梯轴部333的自由端与连接部220传动连接。具体地，如图3和图4所示，阶梯轴部333的自由端呈扁轴状或者为D字形截面，相应地，连接部220上设有与之相适配的连接孔221，阶梯轴部333与连接部220上的连接孔221过盈配合，实现大齿轮330与导板200的传动连接。For the installation of the large gear 330 on the end of the air duct skeleton 100, specifically, a large gear support sleeve 130 is provided on the air duct skeleton 100. The large gear 330 includes a central shaft 331 and a gear portion 332, and the central shaft 331 has A stepped shaft portion 333 located below the gear portion 332 is inserted into the large gear support sleeve 130 and supported on the large gear support sleeve 130, and the large gear 330 is connected to the free end of the stepped shaft portion 333部220 Transmission connection. Specifically, as shown in FIGS. 3 and 4, the free end of the stepped shaft portion 333 has a flat shaft shape or a D-shaped cross-section.
