[0031]多个第一齿轮组13设置于第一安装部111的远离多个叶片12的一侧,例如图1中,第一齿轮组13与叶片12分别位于第一安装部111的相对两侧。 [0031] The plurality of first gear set 13 is disposed on the side facing away from the first plurality of blades 12 of the mounting portion 111, for example, in FIG. 1, the first gear set 13 and the blade 12 are positioned opposite the first two of the mounting portion 111 side. 每一第一齿轮组13包括第一齿轮131和第二齿轮132,其中第一齿轮131与第二齿轮132相互啮合并交替设置于第一安装部111,第一齿轮131与第一转轴121固定连接,如此,当第一齿轮131转动时即可带动第一转轴121转动。 Each of the first gear set 13 includes a first gear 131 and second gear 132, wherein the first gear 131 and second gear 132 meshing with each other and are alternately disposed on the first mounting portion 111, the first gear 131 and the first shaft 121 is fixed connection, so, when the first driven gear 131 is rotated to a first rotation shaft 121 rotates. 第二齿轮132的第二转轴1320与第一安装部111连接,且第二齿轮132可相对第一安装部111绕第二转轴1320转动。 The second gear 132 of the second rotary shaft 1320 is connected to the first mounting portion 111, and the second gear 132 relative to the first mounting portion 111 may be rotated about a second rotary shaft 1320.

[0032]请继续参照图1和图2所示,当向第一齿轮131或者第二齿轮132施加第一方向上的力时,多个第一齿轮组13中第一齿轮131与第二齿轮132因相互啮合而发生连动以带动第一转轴121旋转,进而带动多个叶片12的转动,以使该通气结构处于开启状态或关闭状态。 [0032] Still referring to FIGS. 1 and 2, when a force is applied in a first direction to a first gear 131 or second gear 132, a plurality of first gear set 13 of the first gear 131 and second gear 2 132 occurs due to the interlocking engagement with each other to drive the first shaft 121 is rotated so as to drive the rotation of a plurality of blades 12, so that the venting structure is in open or closed state. 当该通气结构处于开启状态时,气流可通过该通气结构;当该通气结构处于关闭状态时,气流不能通过该通气结构;并且,本发明多个第一齿轮131和多个第二齿轮132交替设置且相互啮合,因此,可以实现多个叶片12的同时转动。 When the vent structure in the ON state, the gas flow through the vent structure; when the vent structure in the closed state, the air flow can not pass through the vent structure; and, the present invention is a plurality of first gear 131 second gear 132 and a plurality of alternating arranged and engage with each other, and therefore, can be realized simultaneously a plurality of blades 12 rotatably.

[0033]进一步的,第一安装部111和该第二安装部上具有安装孔,第一转轴121的相对两端分别装入两个该安装孔以使第一转轴121于该安装孔内可转动。 [0033] Further, the first upper mounting portion 111 and the second mounting portion having a mounting hole, opposite ends of the first shaft 121 respectively, into the two mounting holes so that the first shaft to the mounting hole 121 may be rotation.

[0034]本实施例中,多个第一齿轮131的直径相同,从而使得多个第一齿轮131的角速度相同,即多个第一齿轮131可转动相同的角度,进而使得与多个第一齿轮131连接的多个叶片12转动相同的角度,从而实现了多个叶片12的同步转动。 [0034] embodiment, a plurality of the same diameter as the first gear 131 of the present embodiment, so that the angular velocity of the plurality of first gear 131 is the same, i.e., a plurality of first gear 131 rotatable at the same angle, thereby making the first plurality a plurality of blades 131 connected to the gear 12 is rotated the same angle, in order to achieve synchronous rotation of a plurality of blades 12.

[0035]进一步的,第二转轴1320与第一安装部111固定连接,且第二齿轮132相对第二转轴1320可转动。 [0035] Further, the second shaft 1320 and the first mounting portion 111 is fixedly connected, and the second gear 132 relative to the second rotatable shaft 1320. 当然,于其它实施例中,第二转轴1320亦可以设计成与第一安装部111枢接,第二转轴1320与第二齿轮132固定连接,如此当通过马达提供驱动力时,马达可与第二转轴1320的凸出第二齿轮132的部分固定连接,以实现该马达驱动第二转轴1320转动,进而带动多个第一齿轮组13转动。 Of course, in other embodiments, also the second shaft 1320 may be designed to contact with the first pivot mounting portion 111, a second rotary shaft 1320 is fixedly connected with the second gear 132, so when the driving force is provided by a motor, the motor may first two projecting portions 1320 of the second shaft gear 132 is fixedly connected, in order to achieve the second motor drive shaft 1320 is rotated, thereby bringing a plurality of first gear set 13 rotates. 需要特别说明的是,上述两种第二转轴1320的设置方式,都可以采用以下两种方式进行驱动:第一种是使用者手动使任意一个第一齿轮131或者第二齿轮132转动,实现多个第一齿轮组13转动;第二种是,以马达为驱动力,且该马达上具有传动齿轮,该传动齿轮与任意一个第一齿轮131和/或第二齿轮132啮合,当该马达驱动该传动齿轮转动时,该传动齿轮的转动会带动与其啮合的第一齿轮131和/或第二齿轮132转动,实现多个第一齿轮组13的转动。 Of particular note is that the two second shaft arrangement 1320, will be driven in two ways can be employed: The first is that the user manually to any one of the first or the second gear 131 rotates gear 132, multi- a first gear set 13 rotates; second, the driving force of a motor, and the motor having a driving gear, a first gear 131 and / or the drive gear meshing with the second gear 132 any, when the drive motor when the transmission gear, the first gear 131 will drive rotation of the transmission gear engaged therewith and / or the second gear 132 rotates, effect rotation of the plurality of first gear set 13. 多个第一齿轮组13的驱动方式并不以上述为限,具体由设计人员根据实际情况而定,在此不再赘述。 A plurality of first gear set 13 is not driven in the above-described embodiment is limited, particularly in accordance with the actual situation by the designer, are not repeated here.

[0036]进一步的,当该通气结构处于开启状态时,相邻两个叶片12的间距等于两个第一齿轮131的半径与位于该两个第一齿轮131之间的第二齿轮132的直径之和,其中该两个第一齿轮131分别与该两个叶片12对应的第一转轴121连接。 [0036] Further, when the vent structure in the on state, two adjacent vanes 12 is equal to the pitch diameter of the first two gears 131 located at the radius of the second gear of the two gear 131 between the first 132 sum, wherein the two first gears 131 are respectively connected to the two first rotary shaft 12112 corresponding blade.

[0037]于实际应用中,多个第一齿轮131与多个第二齿轮132的直径都相同,对应多个叶片12的宽度相同,则当该通气结构处于开启状态时,相邻两个叶片12的间距等于第一齿轮131或者第二齿轮132的直径的两倍;当该通气结构处于关闭状态时,通气结构的厚度等于第一齿轮131或者第二齿轮132的直径,即该通气结构的厚度由第一齿轮131或者第二齿轮132的直径决定,而第一齿轮131或者第二齿轮132的直径由相邻叶片12之间的间距也即叶片12的尺寸决定,也就是说,该通气结构的厚度由叶片12的尺寸决定,因此,叶片12的宽度越小,则第一齿轮131和第二齿轮132的直径越小,通气结构的厚度也越小,从而利于薄型化的需求。 [0037] In practical applications, the diameter of the plurality of first gear 131 and the plurality of second gears 132 are the same, the same width corresponding to the plurality of blades 12, the vent when the structure is in the ON state, two adjacent vanes 12 or 131 is equal to the pitch twice the diameter of the first gear of the second gear 132; and when in the closed state of the vent structure, the vent structure is equal to the thickness of the diameter of the first gear 131 or second gear 132, i.e., the vent structure the thickness is determined by the diameter of the first gear 131 or second gear 132, and the diameter of the first gear 131 or second gear 132 by the spacing between adjacent vanes 12 determines the size of the blade 12 i.e., that is, the vent the thickness is determined by the size of the blade structure 12, and therefore, the smaller the width of the blade 12, the diameter of the first gear 131 and second gear 132 is smaller, the smaller the thickness of the vent structure, thereby facilitating thickness reduction demand.

[0038]并且,当多个第一齿轮131与多个第二齿轮132的直径都相同,叶片12的宽度相同时,本发明通气结构的厚度小于传统的连杆组通气结构的厚度。 [0038] Further, when the diameter of the plurality of first gear 131 and the plurality of second gears 132 are the same, the same width of the blade 12, the thickness of the ventilation structure of the present invention is less than the thickness of a conventional ventilation structure linkage. 传统的连杆组通气结构包括叶片和安装部组,叶片上有第一叶片转轴和第二叶片转轴,安装部组包括固定连杆和可动连杆,该固定连杆使该第一叶片转轴在该固定连杆上的特定位置上绕着轴心转动,该可动连杆使该第二叶片转轴在可动连杆上的特定位置上绕着轴心旋转,传统的该连杆组通气结构的厚度等于该第一叶片转轴的直径、该第二叶片转轴的直径、该第一叶片转轴和该第二叶片转轴的转轴间距以及该可动连杆的局部厚度之和,其中,以相邻叶片12之间的间距为18.0毫米为例进行比较,该第一叶片转轴通常的直径为1.5毫米,该第二叶片转轴通常的直径为1.5毫米,该转轴间距通常为6.75毫米,该可动连杆的局部厚度为2.0毫米,因此,该传统的连杆组通气结构的厚度为11.75;而本发明通气结构的厚度为该间距的一半,即为9.0毫米,显然小于传统的连杆组 Traditional vent linkage structure includes a blade and a mounting portion groups, the blade has a first blade and a second blade shaft rotation axis, the fixed link includes a mounting portion groups and a movable rod, the fixing rod blade such that the first rotary shaft rotatable around an axis at a specific position on the fixed link, the link movable blade so that the second axis of rotation around an axis at a specific position on the movable rod, the linkage conventional ventilation thickness of the structure is equal to the diameter of the blade of the first rotary shaft, the shaft diameter of the second blade, the first blade shaft and the rotating shaft of the second blade pitch rotation shaft and the local thickness of the movable link, and wherein, relative 12 o the blade pitch of 18.0 mm between the example for comparison, the first blade shaft diameter typically of 1.5 mm, the second blade shaft diameter typically of 1.5 mm, the spindle spacing is typically 6.75 mm, the movable link local thickness of 2.0 mm, and therefore, the thickness of the conventional aeration linkage structure is 11.75; and the thickness of the ventilation structure of the present invention for a half pitch, namely 9.0 mm, is clearly less than conventional linkage 通气结构的厚度。 The thickness of the ventilation structure. 并且需要特别说明的是,该转轴间距影响马达的施力矩和固定连杆的结构厚度,因此,该转轴间距不是自由参数,不能随意变动,从而限制了传统连杆组通气结构的厚度,不同于本发明中,通气结构厚度随着叶片12的尺寸的减小而减小,即通气结构的厚度可自由调降。 And it should be particularly noted that the spacing on the shaft of the motor torque applied to a structure and a thickness of the fixed link, and therefore, the spindle spacing is not a free parameter and can not change, thus limiting the thickness of the conventional ventilation structure linkage, unlike in the present invention, the thickness of the structure decreases the size of the ventilation vanes 12 is reduced, i.e., the thickness of the vent structure may be cut free.
