Description

 The technical solution of the glove compartment of the instrument panel with a backlight switching device that can be used in the automotive industry is claimed.

 Known design of the inner glove box of a car, described in the application of the UK N 2013141 (publ. 08.08.79.). The glove box is installed on the dashboard and is made in the form of a box with a lid mounted on the axis and equipped with a rotation limiter.

 The disadvantage of this technical solution is the lack of illumination of the inner cavity of the glove box.

 From the literature it is known the technical solution of the glove box of the instrument panel of the car with the backlight device of the internal cavity. The glove box is made in the form of a box with a lid equipped with turn limiters installed on the vehicle dashboard. In addition, the glove box contains a backlight switch made in the form of an end contact switch located in the upper corner, the push rod of which is spring-loaded outward from the box cavity and interacts with the lid when it is closed.

 In the glove box examined, such a switch installation leads to a skew of the lid, which reduces the consumer properties of the structure as a whole.

 The closest is the technical solution of the glove compartment of the instrument panel with the backlight switching device described in the utility model of the Russian Federation N 4945 (published on September 16, 1997), taken as a prototype.

 The indicated glove compartment of the instrument panel is made in the form of a box with a lid mounted on an axis and equipped with a rotation limiter, one end of which is rigidly connected to the lid, and the other extends into the panel. The backlight switching device is made in the form of a magnetically sensitive switch with normally closed contacts, located opposite the trajectory of the rotation limiter, and a permanent magnet located on the rotation limiter. The switch is installed by means of a cylindrical case in the hole of the wall of the instrument panel adjacent to the outer side of the side wall of the glove box, and the magnet, also by means of a cylindrical case, is in the through hole of the rotation limiter, with the end flanges of the cases facing each other.

 The disadvantage of the prototype is the complexity of the design of the instrument panel, in which an additional wall is formed for installing a magnetically sensitive switch. In addition, the reliability of turning on the backlight is insufficient, since even a slight deformation of the rotation limiter of the cover, an elongated element, can lead to the withdrawal of the magnet from the switch.

 The objective of the invention is to simplify the design of the instrument panel and increase the reliability of the inclusion of illumination of the glove box.

 The specified task in the glove compartment of the instrument panel with the backlight switching device, made in the form of a box with a lid mounted on an axis, in which the backlight turning device is formed by a magnetosensitive switch located opposite the permanent magnet associated with the lid, is solved by the fact that the magnetosensitive switch is installed in the wall a box of a glove box facing the inner surface of the lid provided with an end protrusion in which a magnet and at least one loop extending extend I to the axis associated with the instrument panel.

 The cover is made with the possibility of movement on the axis, and the plane in which the trajectory of the magnet is located passes, as a rule, through the magnetically sensitive switch. The magnetosensitive switch and magnet are installed mainly by means of cylindrical bodies with end flanges facing each other, while the contacts of the switch are made normally closed.

 The magnetosensitive switch can be made in the form of a reed switch.

 The above set of features in comparison with the prior art allows us to conclude that the claimed technical solution meets the condition of "novelty." At the same time, the combination of distinctive features, leading to the solution of the problem, does not explicitly follow from the prior art, therefore, the claimed technical solution meets the condition of "inventive step".

 Figure 1 shows a longitudinal section of a glove box dashboard at the installation site of the switch.

 The glove box 1 of the panel 2 of the devices is made in the form of a box with a lid 3 installed with the possibility of movement on the axis 4, connected with the panel 2 of the devices. The glove box 1 contains a backlight switching device, made in the form of a magnetically sensitive switch 5, for example, a reed switch, with normally closed contacts, located in the plane of the path of movement of the permanent magnet 6, located on the end protrusion 7 of the inner surface of the cover 3. The switch 5 is installed by means of a cylindrical housing the opening of the wall 8 of the box of the glove box 1 facing the inner surface of the cover 3. The magnet 6 is installed in the protrusion 7 of the cover 3 also by means of a cylindrical housing, while the end flanges of the housings are facing each other. In addition, in the protrusion 7 is installed at least one loop 9, extending from the cover 3 to the axis 4 and fixed on it.

 In the closed state of the glove box 1, the permanent magnet 6 is located opposite the reed switch 5, the contacts of which are open under the influence of a magnetic field. When opening the cover 3, the magnet 6 moves away from the reed switch 5. The magnetic flux density decreases, the contacts of the switch 5 are closed, including the lamp of the ceiling light 10 of the interior of the glove box 1.
