Description

Technical field to which the utility model belongs

The utility model relates to the equipment of vehicles and concerns a product intended for protection from sunlight, mainly for a vehicle window.

State of the art

It is known from the state of the art:

1. A shutter mechanism for a vehicle window [1] in which a curtain panel is attached to the drum and this drum is installed between the decorative linings of the window pillars.

2. A light-shielding device for a vehicle window [2] containing a movement mechanism that includes a base with a pair of drums installed on it, in which curtain curtains are fixed with one of their edges, to the second edge of which transverse strips are attached, and the curtains with transverse strips are installed with the possibility of plane-parallel movement along the guides fixed on the vehicle body skin.

3. Known roller shutters that are installed on vehicles [3]

A significant drawback of solutions from sources [1] and [2] is that they are used inside the vehicle, which puts restrictions on the installation of additional equipment in the vehicle, which must be located or uses the vehicle window. When installing additional equipment that is located near the glass of the vehicle, for example, a mobile display [4, 5], a flexible mobile display [6] together with a mobile information system [7], it is impossible to arrange the proposed solutions, since the surface of the canvas is located directly at the window surface from inside the passenger compartment and the window is covered by a mobile display or other device. In addition, these solutions cannot be automated and involve manual control of the shutter opening and closing.

A significant disadvantage of the solution from the source [3] is the massive structure and the inability to install it on the glass of the vehicle. In addition, this solution is intended for installation on flat surfaces, which puts a limitation on the use of this solution in conjunction with vehicle glasses that have a non-planar shape (the glass is curved with a certain or variable radius on one or more sides).

Disclosure of the essence of the invention

The technical problem to be solved by the claimed utility model is the development of a product capable of protecting the vehicle interior, devices located under the glass in the vehicle interior from exposure to direct sunlight and excessive heating, while the product must be able to be remotely controlled for opening and closing curtains.

This task is essential, since, for example, if one of the variants of the mobile display [4, 5, 6] is used, installed from the passenger compartment on the glass of the vehicle, its overheating will lead to the failure of its components, for example, a liquid crystal matrix, whose operating temperature is not must exceed 50 ° C. If the temperature exceeds the operating temperature of the device installed under the glass of the vehicle, a signal is sent to the light protection device to close the shutter. After the device has cooled down, a signal is given to open the shutter.

The technical result obtained when installing a product made according to the claimed utility model is to reduce the temperature of the vehicle interior.

The problem is solved due to the fact that fasteners are installed on the vehicle glass from the outside, the main shaft is installed on the fasteners, which contains an electric motor with a controller and rollers. The mountings must be of such a height that the shaft and other elements do not touch after installation of the vehicle glass. A shutter is fixed to the shaft with its edge, two leashes are attached to the shutter, which play the role of tensioners and guides that pass through the rollers of the leash and are wound on the shaft on both sides.

Implementation of the product:

The light-shielding device for the exterior vehicle window (1) is installed on the vehicle (2) outside on the glass (3), as indicated in Figures 1 to 8. Figures 1 to 4 show an installation option in which the main elements of the device (1a) are located on the upper part of the glass of the vehicle, respectively, the curtain goes down and rises from the upper (Fig. 3,4) part of the glass. The main elements of the device (1a) are the shaft, the electric motor, the gearbox, the body - the fairing. The location of the main elements of the device is possible in the lower part of the glass. Figures 5 - 8 show an installation variant in which the main elements of the device (1a) are located on the left side of the vehicle glass (3) and the shutter (4) moves from left to right (Figs. 7, 8). The location of the main elements of the device is possible on the right side of the glass.

To install the product on the glass of the vehicle (3), the shaft mounts (10) and the drive roller mounts (11) are provided in advance, mounted on the glass from the outside by means of an adhesive joint (12), as indicated in FIG. 9. Adhesive bonding can be done with UV glue or other method. The light protection device itself for the vehicle glass of external design consists of a shaft (5), at the ends of which the shaft supports (5a) are installed, intended for installation on the shaft mounts (10) and two carrier roller supports (9a), containing the leash rollers (9) and installed on the carrier roller mounts (11). A curtain (4) is fixed on the shaft (5) with its edge (4), which contains leashes (8), playing the role of tensioners and guides that pass through the rollers of the leashes (9) and is wound on the shaft (5) so that the leashes do not intersect with the curtain ( 4). A dense material that does not transmit visible light, films that do not transmit infrared radiation can be used as a curtain. The levers (8) and the shutter (4) are connected through a hole in the shutter (8) using a knot or otherwise. The leash can be a metal or nylon cable. The electric motor (6) is installed inside the shaft (5) and has attachments to the shaft support (5a), this electric motor (6) transmits the torque through the planetary gearbox (7) to the shaft (5). This electric motor is controlled by a controller (6a), which can receive a signal to turn the electric motor on or off remotely either via a wired interface (UART, SPI, I2C), or via a wireless data interface (WiFi, BlueTooth). To protect the device, a housing is used - a fairing (13), which protects the mechanical and electrical parts of the device from the external environment.

Let us consider the principle of operation of a light-shielding device for glass of an external vehicle, if the curtain is wound on a shaft and the glass of the vehicle is open and it is necessary to close the glass with a cloth to reduce the temperature of the device located outside the window or the interior of the vehicle. When the signal to turn on the device is remotely sent to the controller (6a), the electric motor (6) is turned on, which rotates the shaft (5) through the gearbox (7).). The levers (8), winding on the shaft (5), pull the shutter (4) towards themselves, unwinding it from the shaft (5). If it is necessary to open the vehicle window, a signal is sent to the controller to turn off the device and the shutter (4), winding on the shaft (5), pulls the leashes (8).
