The specific embodiment
Below in conjunction with accompanying drawing, a preferred embodiment of utility model is done detailed description.
As shown in Figure 1; The air channel of the vehicle air conditioner that the utility model provides; Comprise main air duct 1, be arranged on main air duct 1 upper reaches air inlet duct 2, be arranged on the exhaust passage 3 in main air duct 1 downstream and be arranged on the drive motors 4 on the main air duct 1; Wherein, as shown in Figures 2 and 3, main air duct 1 comprises upper shell 11 and lower house 12; Upper shell 11 assembles through buckle with lower house 12 or assembles through bolt, the first passage 14 and second channel 15 that are provided with roller shutter air door 13 between upper shell 11 and the lower house 12 and are communicated with roller shutter air door 13.
Like Fig. 4 and shown in Figure 5; Roller shutter air door 13 comprises the roller shutter 133 between first spool 131, second spool 132 and first spool 131 and second spool 132; Roller shutter 133 can be crispaturaed in inner chamber 1311 and the inner chamber 1321 in first spool 131 and second spool 132 automatically; By this, first spool 131 and second spool 132 are clockwise or be rotated counterclockwise and drive roller shutter 133 and between first spool 131 and second spool 132, move; Roller shutter 133 is preferably processed by the perspex material of good toughness, and thickness is preferably 2mm.
At first passage 14 correspondence positions first air door 134 is set; At second channel 15 correspondence positions second air door 135 is set; Between first air door 134 and second air door 135 driving shaft 136 is set, driving shaft 136 is driven by drive motors 4, between first air door 134 and first spool 131 first driven shaft 137 is set; Second driven shaft, 138, the first driven shafts 137 and second driven shaft 138 are set between second air door 135 and second spool 132 to be driven by roller shutter 133; Roller shutter air door 13 is communicated with 2 through the opening 16 between first spool 131 and second spool 132 with air inlet duct, and first passage 14 is communicated with exhaust passage 3 with second channel 15.The said driving shaft 136 and first driven shaft 137 preferably are arranged on the inboard of roller shutter air door 13, and said second driven shaft 138 is arranged on the outside of roller shutter air door 13.Because roller shutter air door inboard has the wheel toothing; Driving shaft 136 can play driving action through the gear teeth meshing with roller shutter air door 13 both sides; So being arranged on the inboard of roller shutter air door 13, driving shaft 136 cooperates with the gear teeth; First driven shaft 137 need cooperate rotation to support the roller shutter air door with driving shaft 136, makes roller shutter 133 perpendicular to passage 14, so the driving shaft 136 and first driven shaft 137 preferably are arranged on the inboard of roller shutter air door 13.And 138 effects of playing guiding of second driven shaft self need not taken turns toothing, and for simplifying the structure of second driven shaft 138, second driven pulley is arranged on the outside of roller shutter air door 13 and matches.
During use; Drive motors 4 drive driving shafts 136 clockwise be rotated counterclockwise; Driving shaft 136 rotates drive roller shutter 133 and between first spool 131 and second spool 132, moves; Adjust the corresponding connected relation between first air door 134 and second air door 135 and first passage 14 and the second channel 15, thus the air quantity in the control air channel.The air channel that present embodiment provides has three kinds of ventilation operation patterns, and first pattern is that first air door 134 and second air door 135 are opened simultaneously, and second pattern is that first air door 134 is closed; Second air door 135 is opened, and three-mode is that first air door 134 is opened, and second air door 135 is closed; Wherein, first pattern is default conditions, because under three-mode; Trend is more straight in the middle of the air channel, and the path that wind passes through is the shortest under three-mode, and the resistance coefficient of corresponding wind channels is also minimum; When under the identical condition of air-conditioning intake, the resistance of three-mode is minimum, and the air quantity that can distribute is maximum.For example; When the air channel was in default conditions, in order to reach maximum intake, the button on driver's rotating panel was to three-mode; Motor turns clockwise; The revolution of driving shaft axle rotation multiply by girth that the driving shaft axle rotates a circle equal first air door 134 and second air door 135 apart from the time, duty converts three-mode into, can obtain maximum quantity of wind.
In order to prevent driving shaft 136 idle running, on the roller shutter 133 gear teeth 139 can also be set.As a kind of preferred version of the utility model, the two edges of roller shutter 133 are respectively arranged with row's gear teeth 139 in the present embodiment, the said gear teeth 139 and driving shaft 136 and 137 engagements of first driven shaft, and in the present embodiment, the gear teeth 139 width are preferably 5mm.The size of the gear teeth can design according to driving shaft 136, driving shaft 136 can according to self the axle diameter design.
Shown in Fig. 6 a and Fig. 6 b; Fig. 6 b is the enlarged diagram of Fig. 6 a at the A place; Roller shutter 133 width in the present embodiment are greater than the width of first passage mouth 14 or second channel mouth 15; Also be provided with the groove 5 of taking in the roller shutter edge on said upper shell and the lower house, said roller shutter edge is the part roller shutter of roller shutter greater than first passage mouth 14 or second channel mouth 15.Form groove 5 through bolt or buckle butt joint upper shell with lower house, containing section roller shutters in the groove 5, and then the operation of roller shutter played position-limiting action, prevent that first air door or second air door from departing from perhaps second wind passage mouth of first wind passage mouth.A kind of preferred version as present embodiment; Roller shutter 133 width are than the big 10mm of width of first passage mouth 14 or second channel mouth 15; Be the roller shutter 133 monolateral interior 5mm of groove that extend to; The height of groove 5 is preferably 8.5mm, and the wall thickness of upper shell 11 or lower house 12 is 1.5mm, and the gap of roller shutter 133 and groove 5 is preferably 2mm.
As a kind of preferred version of the utility model, as shown in Figure 7, be respectively arranged with tenon on air inlet duct 2 and the exhaust passage 3; Main air duct 1 is provided with and the suitable tongue-and-groove of said tenon; Air inlet duct 2 is fixed with main air duct 1 joggle, and exhaust passage 3 is fixed with main air duct 1 joggle, in addition; Monolateral gap 2mm preferably is set between tongue-and-groove and tenon; To guarantee not exist in the assembling process phenomenon of clamping stagnation, in order further to guarantee the sealing in air channel, main air duct 1 can also adopt sponge to seal with the junction of air inlet duct 2 and exhaust passage 3.
The foregoing description only supplies to explain the usefulness of the utility model; And be not to be the restriction to the utility model; The those of ordinary skill in relevant technologies field under the situation of spirit that does not break away from the utility model and scope, can also be made various variations and modification; Therefore all technical schemes that are equal to also should belong to the category of the utility model, and the scope of patent protection of the utility model should be limited each claim.
