The automobile air conditioner control panel that air quantity knob controls with big current, the conversion of air quantity knob gear is by knob housing rotational motion, and axle maintains static in knob, the conversion of knob gear can not at pcb board upper knob shaft core position perforate direct-drive air quantity assembly, and namely operation knob can not Direct driver air quantity assembly.In order to solve above-mentioned technical barrier, some producers arrange a circle external tooth on knob base, and be connected with air quantity assembly by gear mechanism, such complex structure, assembling difficulty, productive costs is high, and easily produces stroke drop in transmission process, can affect the synchronism that air quantity assembly and knob shell move.
Utility model content
Technical problem to be solved in the utility model be to provide a kind of structure simple, for the transmission device of automobile air conditioner control panel.
The technical solution of the utility model is as follows: a kind of transmission device for automobile air conditioner control panel, knob shell is set above pcb board, axle in knob is provided with in knob shell, the below of pcb board arranges air quantity assembly, it is characterized in that: install transmission circle in the bottom of described knob shell, the bottom one extension downwards of this transmission circle, forms transmission driving lever, described transmission driving lever through the circular hole that pcb board is offered, and is connected with the transmission handle that air quantity assembly top is installed.
Adopt above technical scheme, transmission circle and knob shell assemble fastening, are connected through pcb board with transmission handle again, and transmission handle is fixed on air quantity assembly, and operation knob shell drives transmission circle, transmission handle is synchronized with the movement, thus realize the object driving air quantity assembly.Compared with background technology, the utility model structure simplifies greatly, and not only easily, efficiency of assembling is high, and decreases mould, effectively reduces productive costs in assembling.
Described transmission circle is ring set structure, the outer circumference surface on transmission circle top is formed with multiple well-distributed discount, discount is up-small and down-big wedge shape, and the top of described transmission circle is stretched in knob shell, and the catching groove that arrange corresponding on knob shell of the discount on transmission circle is interlockingly connected.The moulding of above structure driven circle is simple, tight with knob shell spiral-lock, and the fixing that both connect is good, and dismounting is convenient; Whole transmission device adopts concentric shafts design, and can guarantee that transmission circle and transmission handle are synchronized with the movement, namely knob switches a gear, air quantity assembly corresponding switching gear.
The outer circumference surface on described transmission circle top is formed with multiple well-distributed limit rib, this limit rib is the strip shape that above-below direction extends, and limit rib and discount are arranged at circumferentially interval, described limit rib to snap on knob shell in the corresponding opening arranged.Transmission circle interval arranges assembling button bit and limit rib, is greater than 1/2nd of part body height, fully ensure that the operational stability of transmission circle, improve product quality with the fit dimension of knob shell.
Described transmission handle is made up of sleeve and cantilever, sleeve set in air quantity assembly top is arranged on spindle nose, both flush fits; Described cantilever is " L " shape, and crosspiece and the sleeve of cantilever are connected as a single entity, and the perpendicular section of cantilever offers slot, the slot grafting flush fit on described transmission driving lever and cantilever.The moulding of above structure driven handle is simple, and be connected firmly with air quantity assembly, dismounting is convenient; Transmission circle and transmission handle slot precision-fit, when avoiding rotary motion there is stroke drop in transmission circle and transmission handle, ensure that being synchronized with the movement therebetween.
Beneficial effect: the utility model structure is simple, parts are few, assembling is easy, productive costs is low, stable drive is reliable, can not produce stroke drop in transmission process, effectively ensure that the synchronism that air quantity assembly and knob shell move.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the grafting schematic diagram of transmission circle and transmission handle.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1 and Figure 2, the utility model is made up of axle 2, transmission circle 3, pcb board 4, transmission handle 5 and air quantity assembly 6 etc. in knob shell 1, knob.Wherein, arrange knob shell 1 above pcb board 4, be provided with axle 2 in knob in knob shell 1, in knob, axle 2 maintains static, and knob shell 1 can rotate by axle 2 in knob.Transmission circle 3 is provided with in the bottom of knob shell 1, transmission circle 3 is ring set structure, and the outer circumference surface on transmission circle 3 top is formed with multiple well-distributed discount 32, and discount 32 is up-small and down-big wedge shape, the number of discount 32 is determined according to actual needs, and the present embodiment is preferably four.The top of transmission circle 3 is stretched in knob shell 1, and the catching groove that arrange corresponding on knob shell 1 of the discount 32 on transmission circle 3 is interlockingly connected, and transmission circle 3 and knob shell 1 are linked together.The outer circumference surface on transmission circle 3 top is formed with multiple well-distributed limit rib 33, limit rib 33 is preferably four, the strip shape that this limit rib 33 extends for above-below direction, and limit rib 33 and discount 32 are arranged at circumferentially interval, limit rib 33 to snap on knob shell 1 in the corresponding opening arranged.
