Abstract

A diversion apparatus, adapted to be arranged at the tail end of a vehicle, includes a diversion assembly and a slide mechanism. The inside of the diversion assembly is hollow and formed an airflow channel. The slide mechanism is arranged fixedly at the tail end of the vehicle body and has slot tracks extended along the lengthwise direction of the tail end of the vehicle body. The diversion assembly arranged on the slot tracks can be activated and slipped thereon. Therefore, the diversion assembly can be slipped on the slot tracks and activated toward the front of the vehicle body to prevent the opening of the door leaf of the vehicle from being hindered by the diversion assembly.

Claims

1. A slippage-typed diversion apparatus for reducing drag of vehicle, adapted to be arranged at a tail end of a vehicle body (2), including:

a diversion assembly (10), an inside of which is hollow and formed an airflow channel (102); and

a slide mechanism (11), which is arranged fixedly at the tail end of the vehicle body (2), and which has slot tracks (112) extended along a lengthwise direction of the tail end of the vehicle body (2), the diversion assembly (10) arranged on the slot tracks (112) being able to be activated and slipped thereon.

2. The slippage-typed diversion apparatus for reducing drag of vehicle according to claim 1, wherein the diversion assembly (10) is a frame body, an outside and an inside of which respectively have an outer deflector (100) and an inner deflector (101), between which the airflow channel (102) is formed.

3. The slippage-typed diversion apparatus for reducing drag of vehicle according to claim 2, wherein the diversion assembly (10) is arranged a first fastener (105) at an outside of the inner deflector (101), and a second fastener (210) arranged correspondingly to the vehicle body (2) is inter-buckled correspondingly with the first fastener (105) together.

4. The slippage-typed diversion apparatus for reducing drag of vehicle according to claim 2, wherein the diversion assembly (10) is arranged a buffer pad (106) at the outside of the inner deflector (101).

5. The slippage-typed diversion apparatus for reducing drag of vehicle according to claim 2, wherein the outer and inner deflectors (100, 101) are respectively shown as an arc configuration.

6. The slippage-typed diversion apparatus for reducing drag of vehicle according to claim 1, wherein the airflow channel (102) is formed an air inlet (103) and an air outlet (104) respectively at a front side and a rear side of the diversion assembly (10).

7. The slippage-typed diversion apparatus for reducing drag of vehicle according to claim 1, wherein the diversion assembly (10) is a long piece body shown as an arc configuration.

8. The slippage-typed diversion apparatus for reducing drag of vehicle according to claim 1, wherein the diversion assembly (10) is arranged a first fastener (105) at an outside of the inner deflector (101), and a second fastener (210) arranged correspondingly to the vehicle body (2) is inter-buckled correspondingly with the first fastener (105) together.

9. The slippage-typed diversion apparatus for reducing drag of vehicle according to claim 1, wherein the slide mechanism (11) further includes two track seats (110) arranged by interspaced to each other and two slip rods (111) connecting the diversion assembly (10) onto the two track seats (110), and the slot tracks (112) are respectively located on the two track seats (110), and the slip rods (111) all have a connection end (113) assembled to one side of the diversion assembly (10) and a slippage end (114) movably arranged in the slot track (112).

10. The slippage-typed diversion apparatus for reducing drag of vehicle according to claim 9, wherein the two track seats (110) are respectively arranged at an upper side and a lower side of one lateral surface at the tail end of the vehicle body (2).
