Description

Technical Field

[0001] The utility model belongs to the technical field of spoilers and relates to a Y-direction unfolding mechanism for a rear spoiler. Background Art

[0002] In an environment where driving safety and driving economy are increasing, car owners often have the need to increase vehicle body stability and reduce fuel consumption on highways to avoid unsafe phenomena such as body shaking and insufficient grip at high speeds. Having better grip and less air resistance is the development direction of the automotive industry.

[0003] The rear spoiler is an important and effective component for increasing the rear grip of the car and reducing the air resistance of the car, and is generally used in hatchbacks and SUV models. At present, the rear spoilers on the market are basically fixed, and cannot change their position according to the dynamic working conditions of the vehicle, and cannot achieve the optimal body stability and air resistance coefficient. A few flippable spoilers can only increase the stability of the vehicle body by adjusting the angle, but while increasing the body stability, it will increase the wind resistance and increase energy consumption, which is not conducive to increasing the vehicle's cruising range.

[0026] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0027] like Figures 1A-5B As shown, a Y-direction unfolding mechanism for a rear spoiler comprises: a driving unit 100, the driving unit 100 is equipped with a rotatable driving block 110; at least one unfolding unit, the unfolding unit comprises a force transmission element 200, an articulated seat 300, an active hinge 400, a driven hinge 500 and a side trim 600, one end of the active hinge 400 is articulated to the articulated seat 300 and the other end is articulated to the side trim 600, one end of the driven hinge 500 is articulated to the articulated seat 300 and the other end is articulated to the side trim 600, one end of the force transmission element 200 is articulated to the driving block 110 and the other end is articulated to the active hinge 400; the driving unit 100 can drive the side trim 600 to extend or retract, and the extension amount of the side trim 600 is determined by the angle of the driving block 110.

[0028] Both the driving unit 100 and the unfolding unit can be installed on the mounting seat. The driving unit 100 can drive the unfolding unit to move so that the side trim panel 600 can be unfolded or retracted. The hinge seat 300, the active hinge 400, the driven hinge 500 and the side trim panel 600 in the unfolding unit constitute a planar four-link 230 structure; when the driving unit 100 rotates, it can drive the driving block 110 to rotate. When the driving block 110 rotates, it transmits torque and movement to the active hinge 400 through the force transmission element 200. The active hinge 400 and the driven hinge 500 can drive the side trim panel 600 to unfold in the Y direction, so that the vehicle body stability and air resistance reach the optimal position.

[0029] It should be pointed out here that the Y direction actually refers to the length direction of the spoiler assembly. When the spoiler assembly is installed at the rear of the vehicle, the Y direction is reflected as the two sides of the vehicle. The Y-direction deployment mechanism can steplessly adjust the Y-direction length of the rear spoiler. When the Y-direction deployment mechanism drives the side trim 600 to deploy, it can increase the wind guide area and windward area of ​​the rear spoiler, that is, provide an additional Y-direction area increase effect, improve the vehicle body stability, thereby reducing the vehicle's driving loss, and improving fuel economy and cruising range.

[0030] The deployment mechanism can continuously adjust the Y-direction length of the rear spoiler, and has the function of increasing the wind guide area and the windward area, thereby increasing vehicle stability and reducing air resistance, which is beneficial to increasing the vehicle's cruising range.

[0031] As Figure 1A-4 As shown, in the above embodiment, there are two unfolding units, and the force transmission elements 200 of the two unfolding units are both hinged to the driving block 110 so that the two unfolding units move synchronously. The driving unit 100 is linked to the two unfolding units through the two force transmission elements 200, so the driving unit 100 can drive the two unfolding units to move synchronously, so that the two side trims 600 are extended or retracted at the same time.

[0032] In the above embodiment, the two unfolding units are respectively located on both sides of the driving unit 100, and the two unfolding units are arranged in a mirror-symmetrical manner.

[0033] like Figures 1A-5B As shown, in the above embodiment, the force transmission element 200 includes a rotating shaft 210, a rotating block 220 and a connecting rod 230. The rotating block 220 is hinged to the driving block 110 through the rotating shaft 210. The rotating block 220 is hinged to one end of the connecting rod 230 through the hinge shaft 240 to form a linkage structure. The other end of the connecting rod 230 is hinged to the active hinge 400. The rotating block 220 has a first degree of freedom of rotation relative to the connecting rod 230, and the linkage structure has a second degree of freedom of rotation relative to the rotating shaft 210.

[0034] In the above embodiment, one end of the rotating shaft 210 is rotatably connected to the driving block 110 and the other end is rotatably connected to the rotating block 220 .

[0035] The force transmission element 200 is a connecting member with two rotational degrees of freedom. The driving element can push or pull the hinge mechanism through the force transmission element 200 to move the hinge mechanism; in the actual structure, the middle part of the driving block 110 is connected to the driving unit 100, the end of the driving block 110 is connected to one end of the rotating shaft 210, and the other end of the rotating shaft 210 is connected to the rotating block 220. The rotating block 220 is hinged to one end of the connecting rod 230 through the hinge shaft 240, and the other end of the connecting rod 230 is hinged to the active hinge 400. There is an angle between the axis of the hinge shaft 240 and the axis of the rotating shaft 210 (in the actual structure, the axis of the hinge shaft 240 is perpendicular to the axis of the rotating shaft 210), so that the rotating block 220 can rotate relative to the rotating shaft 210 and relative to the hinge shaft 240, so that the force transmission element 200 has two degrees of freedom, so that there is no interference when transmitting torque.

[0036] like Figure 2-4 As shown, in the above embodiment, the driving unit 100 is an actuator, the actuator has an output shaft 120, the driving block 110 is connected to the output shaft 120, and the actuator can rotate the driving block 110. The actuator can achieve a stepless adjustment effect, so the side trim 600 can be moved to any position, and finally the rear spoiler can be extended steplessly in the Y direction.

[0037] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0038] In addition, in the present invention, the descriptions of "first", "second", "one", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.
