Specific embodiment

A kind of electric automobile seat air-conditioning device with reference to shown in Fig. 1-7, the air conditioner housing 1 including being in seat shape are described In seat shape namely as shown in fig. 1, shell 1 is substantially l-shaped, is in use mounted on the utility model for shell 1 Inside automotive seat, the inner frame of seat is formed, it is complete by laying the compositions such as sponge, spring, rubber cushion, leather sheath on inner frame Automotive seat.

The preceding facade of the shell 1 also just sets air inlet 2 with opposite shell 1 on front side of Chain cushion；Facade afterwards, Be exactly backrest 1 middle part of the opposite shell in the back side set after air outlet 3；Shell 1 top surface opposite with backrest top Air outlet 4 in setting.1 inside of shell sets wind turbine 5, heat exchanger 6 and movable air door 7.The wind turbine 5 is located under shell 1 The front side in portion and close air inlet 2, in order to ensure the air supply efficiency of wind turbine 5, and are convenient for the installation of wind turbine 5, the wind turbine 5 is best Select crossflow fan 5.

The heat exchanger 6 is inclined at the corner in shell 1, and heat exchanger 6 is used to carry out heat exchange, heat exchange with air Device 6 can both coordinate with mounted air conditioner system, using on-board air conditioner as the heat source and low-temperature receiver of heat-conducting medium in heat exchanger 6；Also may be used To set independent heat source and low-temperature receiver in heat exchanger 6, such as：Electrothermal tube, semiconductor chilling plate etc. pass through independent low-temperature receiver and heat source Heat-conducting medium is heated, is freezed.Then heat exchange is carried out by the heat-conducting medium in heat exchanger 6 and air again.To improve The heat transfer efficiency of heat-conducting medium in hot gas 6, better way is to use glycol water as heat-conducting medium, that is, is changed Heat-conducting medium inside hot device 6 is glycol water.

The namely rotary air door of movable air door 7, in being enough to block the flat of upper air outlet 4 and rear air outlet 3 Plate, that is to say, that movable air door 7 can completely cover upper air outlet 4, can also completely cover rear air outlet 3.It is living When dynamic air door 7 turns to certain position, the air circulation of air outlet 4 in blocking, when turning to another location, air outlet after blocking 3 air circulation.Outwardly extending rotating bar 8 is both provided at left and right sides of 7 one side of movable air door, movable air door 7 is by turning Lever 8 and the left and right sidewall of shell 1 are formed and are hinged, and movable air door 7 is driven by driving mechanism.Driving mechanism can drive movable air door 7 are pivoted about with rotating bar 8.In order to eliminate the influence in the gap between movable air door 7 and shell 1, raising activity wind 7 accuracy when carrying out state switching of door, better way are the 7 front edge of movable air door and the opposite shell of back edge It first is respectively arranged on 1 inner wall keeps out fin 15 and second and keep out fin 16.First, which keeps out fin 15 and second, keeps out fin 16 one side can play the position-limiting action to movable air door 7, on the other hand when the edge of movable air door 7 be overlapped on completely keep out it is convex Better seal effect can be realized when on rib 15.Usual first keeps out fin 15 and the second surface for keeping out fin 15 is additionally provided with One layer of rubber layer.

Manual structure can be used in the driving mechanism of movable air door 7 described in the utility model, such as：7 one side of movable air door One rotating bar 8 extends outwardly and sets swing handle and corresponding locked component, and 8 turns of rotating bar is driven by rotating handles It is dynamic, it is locked after rotateing in place using locked component.

Certainly, better way is that the driving mechanism of the utility model movable air door 7 uses automatic structure, such as：Institute Stating driving mechanism includes being arranged on the servomotor 9 of 1 left or right side outer surface of shell, and servomotor 9 is fixed with shell 1, institute The output shaft for stating servomotor 9 is connected by transmission component with corresponding rotating bar 8, and the transmission component includes the first linking arm 10 and second linking arm 11.First linking arm 10 is vertical with rotating bar 8 and one end and rotating bar 8 are affixed, the first linking arm It is provided with bar hole 12 on 10 along its length, one end of second linking arm 11 is provided with matched short with bar hole 12 Bar 13, the other end are fixedly connected with the output shaft of servomotor 9, and the quarter butt 13 is threaded through in bar hole 12.When servomotor 9 When driving the rotation of the second linking arm 11, the second linking arm 11 drives the first linking arm 10 to rotate, and the first linking arm 10, which drives, to be rotated Bar 8 rotates, and then movable air door 7 is driven to adjust the angle.In use, by be arranged on the operation of console or steering wheel etc. by Button controls servomotor 9, and operation is more convenient.Meanwhile bar hole 12 and quarter butt 13 form the cooperation of mutual /V, prevent Degree, which rotates, causes movable air door 7 to be not tight seal.

The mode that the first linking arm of the utility model 10 is fixedly connected with rotating bar 8, the second linking arm 11 and servomotor 9 The mode that output shaft is fixedly connected is more, such as：It welds, be bolted.In order to easily facilitate installation, better way It is that one end, the second linking arm 11 that first linking arm 10 is connected with rotating bar 8 export the one of axis connection with servomotor 9 End is both provided with inner spline housing 14, and the rotating bar 8 and 9 output shaft of servomotor are both provided with what is be meshed with inner spline housing 14 External splines, the inner spline housing 14 of 10 and second linking arm 11 of the first linking arm are respectively sleeved at rotating bar 8 and servomotor 9 Outside output shaft.

In use, air is entered by air inlet 2 in shell the utility model under the action of wind turbine 5, with heat exchange Device 6 into heating or refrigeration heat exchange, then by upper air outlet 4 and/or after air outlet 3 blow out.The utility model mainly divides For：Ventilated seating blows foot and ventilation-blow three kinds of operating modes of foot, and the switching between Three models is completed by movable air door 7, activity Air door 7 turns to air outlet 3 after closing, in conducting during the position of air outlet 4, then the utility model enters ventilated seating pattern； When movable air door 7 turns to the position of air outlet 3 after the upper air outlet 4 of closing, conducting, then the utility model is into blowing foot pattern； When movable air door 7 turns to the position for simultaneously turning on air outlet 4 and rear air outlet 3, then the utility model enters foot of divulging information-blow Pattern；Function is more diversified, disclosure satisfy that different use demands.Meanwhile the wind turbine 5 set inside the utility model can Accelerate air to flow to rear row seat, and heat exchanger 6 can carry out reheating or refrigeration to air, cooling in summer effect is more preferable, the winter Season heating effect more preferably, can effectively improve the comfort of the comfort, especially rear row seat in riding space.Further, since The utility model is arranged on inside seat when in use, is not take up interior space, rational and compact.
