Below in conjunction with accompanying drawing the concrete structure of the swing mechanism of application the utility model technology is made an explanation.
As shown in Figure 1, a kind of fan comprises column 1 and fan head 2, but described fan head 2 horizontal huntings be arranged on the described column 1.
As Fig. 2 and shown in Figure 5, the swing mechanism of described fan head 2 comprises supporting base 9 that upper branching holder 92 and lower support seat 91 formed, is arranged on the upper frame 4 on the described supporting base 9 and be connected in the drive motor 8 of described upper frame 4 bottoms rotationally.Described upper frame 4 substantially horizontal settings, at the lateral location of described upper frame 4 fan electromotor 5 that is connected, described fan electromotor 5 has rotating output shaft 51, and the flabellum of fan is connected on the described rotating output shaft 51.
As shown in Figure 2, described fan head 2 also comprises housing, and described housing comprises main casing 31, front case 33 and rear case 32, and described upper frame 4, described fan electromotor 5 and supporting base 9 are contained in the described housing.Secondly the rotating output shaft 51 of described fan electromotor 5 center hole that passes front case 33 extends to the outside of housing, and described fan head 2 outsides are provided with the outside that fan screen is connected in described front case 33.
As shown in Figure 2, the control circuit board 6 of control usefulness is set on described upper frame 4, described control circuit board 6 is connected on the double-screw bolt 42 of described upper frame 4 by screw 61; Secondly described main casing 31 is provided with button 34, and described button 34 is electrically connected with described control circuit board 6.
As shown in Figure 2, described upper frame 4 is provided with upper frame positioning hole 41, and described upper frame positioning hole 41 is positioned at the lateral location of described fan electromotor 5, thereby makes the approaching as much as possible described fan electromotor 5 of the strong point of described upper frame 4.The top wall body of described upper frame positioning hole 41 is provided with draw-in groove 410.
As Fig. 2, Fig. 4 and shown in Figure 5, the bottom of described upper branching holder 92 is provided with two groups of ball positioning holes 920 symmetrically, and every group of ball positioning hole 920 is 5, can form 30 ° to 45 ° regulation range.Described ball positioning hole 920 is a kind of superficial pits, and its degree of depth is less than the radius of described ball 94.Described lower support seat 91 is provided with the spring eye 90 adaptive with described ball positioning hole 920, pack in the described spring eye 90 spring 93 and ball 94, described ball 94 embeds in the described ball positioning hole 920 under the promotion of described spring 93, like this when described upper branching holder 92 snaps together up and down with described lower support seat 91, not only can relatively rotate between them, and can form the location of described upper frame 4 by cooperating between described ball 94 and the described ball positioning hole 920 in different amount.Secondly on described lower support seat 91, be provided with and protrude sheet 97, on described upper branching holder 92, adaptive spacing hole 96 is set, thereby described protrusion sheet 97 inserts the rotating range that can limit in the described spacing hole 96 between described upper branching holder 92 and the described lower support seat 91.
As Fig. 2, Fig. 4 and shown in Figure 5, at the center of described upper branching holder 92 through hole 951 is set, at the center of described lower support seat 91 through hole 952 is set, also comprise locating column 7, the top of described locating column 7 is provided with hinge last 72 radially, top is provided with boss 73 radially, the lower end is provided with jump ring groove and jump ring 74, the top of described locating column 7 is passed center hole 951 backs of described upper branching holder and is inserted in the upper frame positioning hole 41 that is provided with on the described upper frame 4, latch 71 snaps in the draw-in groove 410 of described upper frame positioning hole 41 tops setting after inserting described hinge last 72, radial location between described locating column 7 and the described upper frame 4, thereby cooperate by between described latch 71 and the described boss 73, described upper frame 4 axially is connected with described upper branching holder 92 but can radially relatively rotating; Described through hole 952 backs that the center setting of described lower support seat 91 is passed in the bottom of next described locating column 7 are positioned in the through hole 952 at described lower support seat 91 centers by described jump ring 74, and described like this locating column 7 can rotate in described through hole 952 but can not move axially.Described for this reason upper frame 4 can be that the center rotates on described upper branching holder 92 with described through hole (951,952) with described locating column 7, and described locating column 7 is clamped down on described upper frame 4 by means of described latch 71 and is in the same place with described supporting base 9.
According to said structure, under the situation of the cardinal points of not considering to regulate described fan head 2, described ball 94 and corresponding positioning means thereof can be set between described upper branching holder 92 and the described lower support seat 91, also need not separate being set to two parts between described upper branching holder 92 and the described lower support seat 91, get final product but only directly be set on rotationally in the center hole of described supporting base 9 by described locating column 7.Like this, described upper frame 4 just can be only be that rotate at the center with described locating column 7 with the center hole of described supporting base 9.
As Fig. 2, Fig. 3 and shown in Figure 5, the described drive motor 8 of connection below described upper frame 4, described drive motor 8 are to be arranged in 5 minutes with described fan electromotor and can drive fan 2 to rotate in the horizontal direction or the driving sources of swing.
Described drive motor 8 rotates on described supporting base 9 by the described upper frame 4 of swing arm driving.Described swing arm is a kind of mechanism that can form oscillating motion, it comprise with the galianconism 81 of the output shaft fixed connection of described drive motor 8 and with described supporting base be rotatably connected long-armed 82; Wherein said galianconism 81 is rotatably connected to by screw 83 between described long-armed 82, and described long-armed 82 the other end also is rotatably connected on the locating point 921 of described upper branching holder 92 sides by screw 84.Because described locating point 921 is positioned at the lateral location of described upper branching holder 92, when described drive motor 8 rotates, described galianconism 81 rotates and then drives described long-armed 82 rotations on described upper branching holder 92 with the output shaft of described drive motor 8, impelling described upper frame 4 and being arranged on fan electromotor 5 on the described upper frame 4 is that swing in certain angular range at the center on described upper branching holder 92 and with described through hole (951,952).
As Fig. 1, Fig. 2 and shown in Figure 5, the columns 1 below the described fan head 2 are the cylinders of supports fan 2, and described supporting base 9 can directly be connected on the described column 1.Can also be that the control mechanism 10 of nodding is set between described supporting base 9 and described column 1.Thereby the fan head generally can be raised or force down to the described control mechanism 10 of nodding under manual operation height adapts to the crowd who is in different heights.The described control mechanism 10 of nodding inserts in the described column 1.
Described supporting base 9 is positioned on the same axis with described column 1, and both external diameter basically identicals, thereby only needs to be provided with below described main casing 31 circular hole, and described main casing 31 can be around described supporting base 9 or 1 rotation of described column.Described column 1 even can directly be deep in the described main casing 31, overcome traditional product because described supporting, 9 with described column 1 between have the same Adam's apple of similar Abduction arm, the housing of fan electromotor and swing mechanism thereof must be positioned at the structural imperfection on this Adam's apple.
