Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution of the present invention is further described in detail below with reference to the accompanying drawings and the detailed description.
As shown in fig. 1, the sun visor system for a vehicle includes a sun visor 1, aslide rail 2, a motor 3, and a transmission member (not visible).
Theslide rail 2 is mounted on a vehicle ceiling, and may be specifically embedded between an inner panel and an outer panel of the vehicle ceiling. In the figure, twoslide rails 2 are provided, and the twoslide rails 2 are respectively arranged on two sides of the sun visor 1, and in practical implementation, the number of theslide rails 2 is not limited to two. The extending direction of theslide rail 2 is not limited herein, and may extend in the vehicle longitudinal direction, may extend in the vehicle width direction, or may extend in an oblique direction inclined with respect to the vehicle longitudinal direction and the vehicle width direction.
The sun visor 1 has a slide cooperating with theslide rail 2 so as to slide along theslide rail 2. The motor 3 runs by means of electric power, and an output shaft of the motor 3 is in transmission connection with the sun shield 1 through a transmission part so as to drive the sun shield 1 to slide along theslide rail 2. When the motor 3 is operated in the forward direction (i.e. the output shaft of the motor 3 is rotated in the forward direction), the sun visor 1 is driven to slide in the opening direction, and when the motor 3 is operated in the reverse direction (i.e. the output shaft of the motor 3 is rotated in the reverse direction), the sun visor 1 is driven to slide in the closing direction.
Specifically, the transmission component may be a screw nut assembly, the screw is connected to the output shaft of the motor 3, and the nut is connected to the sun visor 1, so as to convert the rotation motion of the output shaft into the linear motion of the sun visor 1.
As shown in fig. 1, the sun visor system further comprises a first controller 5 and a light sensor 4. The light sensor 4 is used for sensing the sunlight intensity. The sunroof has a sunroof glass position sensor (not shown) for sensing the position of the sunroof glass. The first controller 5 is in communication connection with the skylight glass position sensor, the optical sensor 4 and the motor 3, and the first controller 5 automatically controls the motor 3 to run forwards or reversely according to the sensing information of the skylight glass position sensor and the sensing information of the optical sensor 4.
Specifically, the first controller 5 includes a first information obtaining module, a first judging module and a first instruction module. The first information acquisition module is in communication connection with the skylight glass position sensor and the light sensor 4 to acquire the current position and the current sunlight intensity of the skylight glass. The first judgment module is in communication connection with the first information acquisition module to judge whether the skylight glass is opened or closed and whether the current sunlight intensity is equal to or greater than a preset sunlight intensity upper limit value. First instruction module and first judging module and motor 3 communication connection to when skylight glass closed and present sunshine intensity equals or is greater than sunshine intensity upper limit value, send reverse operation instruction to motor 3, make motor 3 drive sunshading board 1 and close, when skylight glass opened, send forward operation instruction to motor 3, make motor 3 drive sunshading board 1 and open.
In detail, an opening position corresponding to when the skylight glass is opened and a closing position corresponding to when the skylight glass is closed may be prestored in the first controller 5, and the opening and closing of the skylight glass may be determined by comparing the current position of the skylight glass with the opening position and the closing position. If the current position of the skylight glass is consistent with the opening position, the skylight glass is opened, and if the current position of the skylight glass is consistent with the closing position, the skylight glass is closed.
As above, this sunshading board system makes first controller 5 according to skylight glass position sensor and optical sensor 4's response information control motor 3 forward direction operation or reverse operation through setting up optical sensor 4 and first controller 5, has realized opening and close sunshading board 1 according to the sunshine intensity automatic according to the difference, and like this, it is more convenient, intelligent to compare manual opening and close sunshading board 1, therefore can promote user experience.
Especially, still predetermine sunshine intensity upper limit value in first controller 5, when present sunshine intensity equals or is greater than sunshine intensity upper limit value, make motor 3 drive sunshading board 1 and close, when present sunshine intensity is less than sunshine intensity upper limit value, make motor 3 drive sunshading board 1 and open, like this, even if the user forgets to close sunshading board 1 when locking the vehicle, sunshading board 1 also can be closed automatically when sunshine intensity is stronger to can prevent that the cabin from being exposed to the sun and the temperature is very high, therefore can promote the user and take the impression.
It should be noted that the upper limit value of the sunlight intensity is pre-stored in the first controller 5, and in actual implementation, the upper limit value of the sunlight intensity may be preset by a manufacturer, or may be set by a user through an input port.
It should be noted that the communication connection described herein may be any connection capable of implementing data transmission, such as a wired connection or a wireless connection.
In the illustrated embodiment, the first controller 5 is connected to the optical sensor 4 and the motor 3 by wires, and in detail, the first controller 5 is connected between the optical sensor 4 and the motor 3 by a wire.

Specifically, a sensing period may be set for the light sensor 4, so that the light sensor 4 uses an average value of the sunlight intensity in one sensing period as the current sunlight intensity, and sends the current sunlight intensity to the first controller 5 once in each sensing period. For example, when the sensing period is set to 30 minutes, the light sensor 4 calculates the current sunlight intensity by dividing the sum of the sunlight intensities for 30 minutes by 30, and transmits the calculated current sunlight intensity to the first controller 5, and since the current sunlight intensity is calculated every 30 minutes, the current sunlight intensity is transmitted every 30 minutes to the first controller 5. Thus, the problem that the sun shield 1 is frequently and automatically opened and closed due to large change of the sunlight intensity in a short time can be avoided.
Specifically, a sunshade plate position sensor can be further arranged to sense the position of the sunshade plate 1, the first controller 5 can control the motor 3 to start and stop according to the position of the sunshade plate, and the specific configuration is as follows: the motor 3 is controlled to be stopped when the sun visor 1 is opened to the fully opened position, or the motor 3 is controlled to be stopped when the sun visor 1 is closed to the fully closed position, or the motor 3 is controlled to be stopped when the sun visor 1 is opened or closed to a preset position between the fully opened position and the fully closed position. In detail, the motor 3 can be controlled to start and stop by controlling the power switch of the motor 3, when the power switch of the motor 3 is switched off, the motor 3 is powered on, so that the motor is started, and when the power switch of the motor 3 is switched on, the motor 3 is powered off, so that the motor is stopped.
