Referring to fig. 1 to 3, an embodiment of the present disclosure provides a flow guiding device 100. The deflector 100 is intended to be mounted on both sides of a van trailer (not shown) and between the vehicle body 10 and the wheels (not shown). The deflector 100 includes: bracket 110, first mounting portion 120, elastic expansion device 130 and apron 140.

The bracket 110 is for fixing under the vehicle body 10. Specifically, in the present embodiment, the support 110 is a triangular support 110. The triangular bracket 110 has a first right-angle side and a second right-angle side perpendicular to and fixed to the first right-angle side. The first right-angle side may be fixed below the vehicle body 10 by means of bolting.

One end of the elastic expansion device 130 is hinged to the bracket 110. The skirt 140 is hinged to the other end of the elastic expansion device 130.

In particular, the elastic expansion device 130 may be a gas spring. The first mounting portion 120 is a gas spring mounting bracket. The lower end of the elastic expansion device 130 is hinged to the bracket 110. The upper end of the elastic expansion device 130 is hinged to the skirt panel 140 through the first mounting portion 120. One end of the first mounting portion 120 is fixedly connected to the skirt panel 140, and the other end of the first mounting portion 120 is hinged to the upper end of the elastic expansion device 130, so that the upper end of the elastic expansion device 130 is hinged to the skirt panel 140 through the first mounting portion 120.

One end of the skirt 140 is hinged to the vehicle body 10, and the other end is a movable end. The skirt panel 140 has a closed state and an open state. By rotating the skirt panel 140 relative to the vehicle body 10, the skirt panel 140 can be switched between the closed state and the open state. The skirt panels 140, when in a closed state, block the space between the vehicle body 10 and the wheels, thereby functioning to reduce wind resistance during travel of the van. The skirt panels 140, when in an open state, expose the space between the vehicle body 10 and the wheels, thereby facilitating access to the underside of the vehicle body 10 for maintenance work when the van-type trailer fails.

When the skirt panel 140 is in the closed state, the skirt panel 140 abuts against the bracket 110 by the restoring force of the elastic expansion device 130. When the skirt panel 140 is in the open state, the restoring force of the elastic expansion device 130 supports the weight of the skirt panel 140.

Specifically, when the skirt panel 140 is in the closed state, one end of the elastic expansion device 130 connected to the skirt panel 140 is inclined toward the bracket 110, and the restoring force of the elastic expansion device 130 is obliquely directed to the bracket 110, so that the acting force of the elastic expansion device 130 on the first mounting part 120 and the skirt panel 140 is obliquely directed to the direction of the bracket 110, thereby the skirt panel 140 is abutted against the bracket 110. Since the skirt panel 140 abuts against the bracket 110 in the closed state, the skirt panel 140 is stable in position in the closed state, and a special locking mechanism is not required to be provided to lock the position of the skirt panel 140, which simplifies the structure.

In the process of switching the skirt panel 140 from the closed state to the open state, the skirt panel 140 rotates with respect to the vehicle body 10, and the elastic expansion device 130 rotates with respect to the bracket 110, so that the angle of the elastic expansion device 130 is changed. At this time, one end of the elastic expansion device 130 connected to the skirt panel 140 is inclined in a direction away from the bracket 110. When one end of the elastic expansion device 130 connected to the skirt panel 140 is inclined in a direction away from the bracket 110, the restoring force of the elastic expansion device 130 is obliquely directed in a direction away from the bracket 110. At this time, the restoring force of the elastic expansion device 130 can support the weight of the skirt panel 140, so that the skirt panel 140 is maintained in the open state, and the position is stable, and a special locking mechanism is not required to be provided to lock the position of the skirt panel 140 in the open state, thereby facilitating the maintenance work below the vehicle body 10.

In the deflector 100, one end of the skirt panel 140 is hinged to the vehicle body 10, and the other end is a movable end, so that the skirt panel 140 can be switched between the open state and the closed state by rotating relative to the vehicle body 10. The skirt panels 140 can play a role in guiding flow when closed, and can conveniently enter the lower part of the vehicle body 10 for maintenance when opened. One end of the elastic expansion device 130 is hinged with the bracket 110, and the other end is hinged with the skirt 140. When the skirt panel 140 is in the closed state, the skirt panel 140 abuts against the bracket 110 by the restoring force of the elastic expansion device 130, so that the skirt panel 140 may be maintained in the closed state. When the skirt panels 140 are in the open state, the restoring force of the elastic expansion and contraction means 130 supports the weight of the skirt panels 140 so that the skirt panels 140 can be maintained in the open state.

In one embodiment, deflector device 100 further includes a second mounting portion 150 and a resilient plunger 160. The elastic plunger 160 is coupled to the bracket 110 through the second mounting portion 150. One end of the second mounting portion 150 is fixedly connected to the bracket 110, and the elastic plunger 160 is mounted to the other end of the second mounting portion 150.

Specifically, the second mounting portion 150 is a plunger mount. The material used for the resilient plunger 160 may be rubber. One end of the second mounting portion 150 is fixedly coupled to the bracket 110, and the other end is provided with a plunger mounting hole (not shown). One end of the resilient plunger 160 is disposed in the plunger mounting hole, and the other end of the resilient plunger 160 extends out of the plunger mounting hole.

Specifically, the outer wall of the resilient plunger 160 is provided with a snap groove (not shown), and the second mounting portion 150 has a protrusion protruding from the sidewall of the plunger mounting hole, the protrusion being located in the snap groove, thereby allowing the resilient plunger 160 to be snapped into the plunger mounting hole.

When apron 140 is in the closed state, the return force of elastic expansion device 130 causes apron 140 to abut against elastic plunger 160. Since the elastic plungers 160 have good elasticity, when the skirt 140 is switched from the open state to the closed state, the skirt 140 collides with the elastic plungers 160, and the elastic plungers 160 can play a role of buffering, so that vibration and noise of the skirt 140 can be reduced.

In one embodiment, one end of the elastic expansion device 130 is hinged to the second mounting portion 150. Specifically, the lower end of the elastic expansion device 130 is hinged to the second mounting portion 150, which facilitates the connection of the elastic expansion device 130 to the bracket 110.

In one embodiment, deflector device 100 further includes a hinge structure 170. The hinge structure 170 includes a rubber strip (not shown), a first connection portion (not shown), and a second connection portion (not shown). The rubber strip can be made of rubber. The first connecting portion is used for fixed connection with the vehicle body 10. The first connecting part is provided with a first hook part which hooks one end of the rubber strip. The adhesive tape can rotate relative to the first hook part. The second connecting portion is fixedly connected to the skirt panel 140. The first connecting part is provided with a second hook part. The second hook part hooks the other end of the rubber strip. The second hook part and the rubber strip can rotate relatively.

Specifically, because the adhesive tape can be for first portion of colluding rotates, the second portion of colluding can rotate with the adhesive tape relatively, and the both ends of adhesive tape are respectively colluded by first portion of colluding and second portion of colluding to the second connecting portion can rotate relative to first connecting portion, second connecting portion and first connecting portion form hinge structure. Because second connecting portion and first connecting portion pass through the adhesive tape relative rotation to noise when can reduce or even avoid second connecting portion and first connecting portion relative rotation, and then noise when can reduce or even avoid skirtboard 140 to open and close.

Another embodiment of the present application provides a van-type trailer. The van trailer comprises a vehicle body 10, wheels and the deflector device 100 in any of the above embodiments. The skirt 140 is hinged to the vehicle body 10 and is located between the vehicle body 10 and the wheel.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
