Abstract

The utility model relates to a ventilation and temperature drop device for the passenger and freight room of an automobile. The frame of the automobile is provided with an exhaust fan. A driving wheel which is fixed on the transmission of the automobile is used to drive the exhaust fan to operate through a belt or a friction wheel transmission. The air intake surface of the impeller of the exhaust fan is provided with a funnel shape cover casing whose tail pipe is sheathed with a flexible pipe which is communicated with the inner part of the steering room of the automobile. Besides, the ceiling of the back part of the passenger and freight room of the automobile is provided with a start stop and slim antitropic skylight.

Description

Ventilation and temperature drop device for automobile

The utility model relates to the aeration-cooling device of a kind of aeration-cooling equipment, the particularly passenger-cargo chamber of automobile.

Existing automobile, be provided with interior environment system and be used for regulating the temperature in luxury bus, general vehicle is in order to reduce cost, all attached aeration-cooling device in addition not, every paramount warm season, complete aeration-cooling by big driving window, this way drawback is a lot of, for example, if meet the rainy day driving, often Yin Gaowen and air were dirty and make driver and conductor's muggy and oppressive after vehicle window was closed, and also can form the fuzzy sight line of one deck aqueous vapor on the Windshield, influenced the safety traffic of vehicle; The fine driving of high temperature, if big driving window, then because of the climate drying, a large amount of sand-limes enters passenger-cargo chamber with the wind, and is extremely unhygienic, is harmful to driver and conductor's health.

The purpose of this utility model is to provide a kind of simple in structure, cheap, need not drive greatly window and the fresh circulation of passenger-cargo room air and have the aeration-cooling device that significant cooling-down effect, Windshield can not form steam yet.

The purpose of this utility model is achieved in that installs an axial-flow type exhaust fan on automobile chassis frame, direct and the operator's compartment communication of flexible pipe of bonded assembly on the case of the inlet end of exhaust fan, belt pulley on the exhaust fan or friction wheel and the belt pulley or the friction wheel that are installed on the propeller-shaft constitute driving device, in addition, open a long and narrow skylight dorsad that can open and close at the rear portion of the passenger-cargo chamber of automobile ceiling, like this, when vehicle ', the power of transmission shaft makes exhaust fan carry out exhaust work to passenger-cargo chamber by above-mentioned driving device, long and narrow skylight dorsad then replenishes fresh air to passenger-cargo chamber simultaneously continuously, because the Rapid Cycle of air, make whole passenger-cargo chamber become an air flue, both reach the purpose of ventilation and heat cooling, and kept passenger-cargo indoor air fresh and clean again.

The utility model is shown in the following drawings:

Fig. 1 is an integral structure scheme drawing of the present utility model;

Fig. 2 is a driving pulley elevation cross-sectional view on the transmission shaft;

Fig. 3 is the birds-eye view of driving pulley on the transmission shaft.

Now contrasting accompanying drawing is described in further detail the utility model: as shown in Figure 1, exhaust fan is made of impeller [7], impeller cover [8], flexible pipe [9], rotating shaft [6], bearing seat [5] and power wheel [4], the construction parameter of impeller is the same with general prerotator, but blade material needs to make of steel plate.Impeller cover [8] is with sheet steel or moulds a square-shaped hopper of making firmly, afterbody is a cylindrical shape, and with plastics coil pipe [9] socket of leading to operator's compartment, one side of case is screwed on the basal plane of installation shaft bearing, exhaust fan rotating shaft [6], the structure of bearing seat [5] all belongs to known, bearing seat [5] is according to the difference of automotive type, can be fixed by bolts to the automobile flute profile, side longeron top or below, be fixed in the above or the additional steel plate [10] of following horizontal expansion on, steel plate [10] is welded on the longeron, and at both ends respectively welds a triangle reinforced rib.The axis hole axial line of bearing seat [5] must with the propeller-shaft axial line in same plane.Driving wheel [2] on follower on the exhaust fan [4] and the propeller-shaft can adopt belt-driving or friction wheel transmission, and when adopting belt-driving, belt [3] adopts laminated v-belt.Shown in Fig. 2,3, the driving wheel on the propeller-shaft adopts band brake type to fix above-mentioned exhaust fan, except that available axial fan, also can adopt centrifugal blower, at this moment, the case adaptor union overhead that connects coil pipe, the air outlet side, the impeller of parallel side blade formula needs totally-enclosed.The last thin-and-long that can open and close the together skylight dorsad of opening backward at the top of back, passenger-cargo chamber.

The utility model has the advantages that: simple in structure, cheap, air fresh cleaning in passenger-cargo chamber during the high temperature season driving, ventilation effect is remarkable, is of value to traffic safety and driver and conductor's health, can be widely used in passenger-cargo chamber ventilated cooling of various vehicles.

Claims

1, the passenger-cargo chamber ventilated cooler of a kind of automobile, comprise the air regulator on passenger-cargo chamber, it is characterized in that on automobile chassis frame, settling an air draft or aspirator system, be communicated with a flexible pipe and automobile cab communication on the case of the inlet end of air draft or aspirator system, the follower on air draft or the aspirator system constitutes a kind of friction gear with the driving wheel that is fixed on the propeller-shaft.Rear portion, passenger-cargo chamber ceiling has together skylight dorsad.

2, the passenger-cargo chamber ventilated cooler of automobile according to claim 1 is characterized in that, described air draft or aspirator system are a kind of exhaust fan or air pump.
