Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a rear spoiler device mounted on the rear end of an automobile.

``Prior Art'' Recently, a spoiler has been installed on the rear end of commercially available automobiles in an attempt to improve driving performance. Coupled with the trend of loosening the legal system, the number of cases is gradually increasing.

Conventional rear spoiler installations d include those that are attached to the vehicle body from the beginning, or those that are retrofitted as a spoiler device that is separate from the vehicle body.

In the former case, it is difficult to construct a large-scale structure due to the nature of commercially available vehicles, and it is generally fixed to a predetermined position. Even in the latter case, it was common to attach the device to the vehicle body, and once it was installed, it could be used as is.

Further, as a conventional example of a spoiler fin integrally provided on the body of an automobile, there is one disclosed in Japanese Unexamined Utility Model Publication No. 63-23191.

According to the same publication, a spoiler fin is provided to form the rear end of the car body, the entire spoiler fin is rotatable, and a signal indicator is provided on the surface facing rearward when the spoiler fin is turned. A vehicle has been disclosed that when the fin is raised, a signal indicator is made visible to those following the vehicle to alert them.

``What the invention is trying to solve, however,
In such conventional rear spoiler devices, the usage state of the spoiler fin during high-speed driving is fixed, and it is difficult to make it have an appropriate rectification function depending on the driving condition, and it is difficult to set it effectively for high-speed driving. There was a problem that if it was left in place, it would increase the resistance when driving at low speeds or get in the way when parking, and if it was not made to be an obstacle at low speeds or when parking, it might not be able to demonstrate its full performance at high speeds.

Furthermore, the device disclosed in the above publication does not adjust the rectification function, but rotates the entire spoiler fin, which not only makes the device bulky, but also causes the spoiler fin to collapse. The problem is that the signal indicators are visible outside even when the lights are on, so they are easily soiled and damaged, and their appearance is not good.

The present invention was made by focusing on these conventional problems, and allows the rectification function to be adjusted when used at high speeds.Also, it is normally hidden and protected, and is effective when necessary. The object of the present invention is to provide a rear spoiler device equipped with a brake lamp that issues a warning when the vehicle is running.

"Means for Solving the Problems" What is the gist of the present invention to achieve these objects?

l A rear spoiler device attached to the rear end of an automobile, in which a spoiler fin is held at the tip of a support leg erected from the vehicle body, and a flap that can be raised and lowered in response to brake operation is provided on the spoiler fin. A rear spoiler device is provided at a rear edge, and is equipped with a brake lamp at a portion that is hidden when the flap is down and appears when the flap is upright.

2. A rear spoiler device that is attached to the rear end of an automobile and can be changed depending on the storage position and usage position.

A guide rail having a sliding guide part in the longitudinal direction is fixed to a base part fixed to the vehicle body, and a movable shoe is moved back and forth between a storage position and a use position, and the sliding guide of the guide rail is fixed in fixed rotation. A spoiler fin is held at the tip of a support leg part that is fitted and held in the movable shoe, and the spoiler fin is equipped with a flap that can be raised and lowered in response to a brake operation at the rear edge.

A rear spoiler characterized by being equipped with a brake light at the part that appears when the flap is erected? It is located at

``Function'' The flap is located at the trailing edge of the spoiler fin and can be raised or lowered depending on the driving condition, complementing the spoiler fin's rectifying function.

In other words, the flap rises and falls according to the brake operation,
When you apply the brakes, the flaps stand up, and when the flaps are up, parts that are normally hidden are revealed, and the brake light installed there lights up.
It issues a high-level warning so that following vehicles can be notified quickly and appropriately.

Spoiler fins cut the air during high-speed driving, reducing air resistance and preventing the vehicle from lifting. During high-speed driving, the flaps are generally integrated with the spoiler fins and laid down, or raised or lowered depending on the situation. For example, when the brakes are applied, the flaps are raised to increase running resistance. Even if you are driving at high speed, you can generate braking force by keeping it upright when you release the accelerator and decelerate.

If the spoiler fin is convertible between the storage position and the use position, when the spoiler fin is in the use position at the rear end of the sliding guide of the moving shoe or guide rail, the spoiler fin shall be erected from the base fixed to the vehicle body. It is held at a suitable distance from the surface of the vehicle body by the supporting legs.

If the spoiler fin gets in the way when you are driving at low speeds, move it forward along the sliding guide section of the movable guide rail, move the support legs forward, and move the spoiler fin to the storage position. Convert.

In the stowed position, the spoiler fin is in a position where it does not protrude significantly from the surface or outer periphery of the vehicle, so it does not disturb airflow, does not get in the way when parking, or creates resistance when driving at low speeds.
