Definitions

  • the invention relates to a rear-view mirror for motor vehicles with a foldable mirror plane to prevent glare.
  • a rearview mirror equipped with a foldable mirror level in which the movements of the mirror level are carried out by an electric motor controlled by the incidence of light, has found considerable interest in the professional world.
  • the previous constructive implementation could not yet meet all requirements.
  • the automatically foldable mirror produced in this way is not sufficiently immune to interference.
  • the mirror is also relatively loud when performing the folding movements. In addition, it could not be manufactured at competitive prices.
  • the object of the present invention is therefore to improve the rear view mirror of the type mentioned in such a way that it is reliable, inexpensive to manufacture and relatively quiet when performing folding movements.
  • This object is achieved in that a drive controlled by a light-sensitive cell is provided for folding the mirror plane, with which the mirror plane is pivotally connected, and in that the light-sensitive cell lies in a light beam which emanates from at least one headlamp of a subsequent motor vehicle .
  • the locking level is folded down before a driver of the motor vehicle is blinded by the light beam of the following motor vehicle.
  • the mirror performs a smooth folding movement that does not affect the handlebars when driving the vehicle.
  • the mirror plane folds back into its original position without the driver having to remove his hands from the steering wheel of the motor vehicle once. He can therefore devote his entire attention to driving the motor vehicle and is therefore able to concentrate his physical and mental strength on mastering the dangerous situation, particularly in critical moments when there is a risk of glare.
  • the rearview mirror is equipped with a drive which is designed as an electric motor which executes all pivoting movements of the mirror plane in the same direction of rotation.
  • a drive which is designed as an electric motor which executes all pivoting movements of the mirror plane in the same direction of rotation.
  • All drive parts remain constantly engaged in the same direction of rotation, so that shocks within the drive are largely avoided.
  • resetting the mirror plane with the help of the force of a prestressed spring is saved.
  • the electric motor does not have to pretension a return spring at the same time as the mirror plane is folded. In this way, the electric motor can be made relatively small. In this way, it is relatively cheap and small in size.

  • Fig. 7 a cross section through an attachment according to the section line VII-VII in Figure 5 and Fig. 8: a plan view of a ver ver with cam gear.
  • a rearview mirror essentially consists of a pivotable mirror housing 1, a support arm 2 and a drive 3. With the aid of the support arm 2, the rearview mirror is fastened in a motor vehicle, not shown.
  • the support arm 2 projects with a bearing 4 into the mirror housing 1.
  • the bearing 4 represents a fixed point in the movably mounted mirror housing 1, around which the mirror housing 1 can be pivoted for the purpose of bending.
  • a large-area contact plate 5 is fastened on the bearing 4. This attachment takes place at various points 6, 7 in order to firmly connect the contact plate 5 to the bearing 4 against the forces required for pivoting the mirror housing 1.
  • the contact plate 5 is provided with drivers 8, 9 which protrude from it in the direction of the drive 3.
  • a free space 10 is provided between the drivers 8, 9, the height of which corresponds to the desired pivoting angle of the mirror housing 1.
  • a gearwheel 11 projects into the free space 10 and, in addition to an electric motor 12 and a threaded spindle 13, belongs to the drive 3. This gear 11 is in engagement with the threaded spindle 13 via corresponding teeth 14 which are attached on its circumference.
  • the gearwheel 11 has two flanks 15, 16 which run plane-parallel to one another.
  • a switching cam 17, 18 is attached to each of the two flanks 15, 16. The two switching cams 17, 18 are offset from one another by an angle of rotation of 180.
  • the teeth 14 are adapted to a thread 19 formed on the threaded spindle 13.
  • the threaded spindle 13 is fastened on a motor shaft 20 which protrudes from the electric motor 12 on the driven side.
  • the electric motor 12 is connected to a voltage source 23 via lines 21, 22.
  • This voltage source 23 can be the vehicle electrical system.
  • the two lines 21, 22 represent the two phases with which the electric motor 12 is connected to the voltage source 23.
  • One of the two phases is divided into two mutually parallel branches 24, 25, one branch 24 of which flows through with the current sen is when the mirror housing 1 is to be pivoted in one direction while the other branch 25 is traversed by the current, when the mirror housing 1 is to perform a pivoting movement in the other direction.
  • the two branches 24, 25 can be connected to the line 22 at one of their ends 27 using a switch 26, while the branches 24, 25 are connected via a relay 29 at an end 28 opposite the end 27. Both the switch 26 and the relay 29 connect the line 22 to the one branch 25 in one switching position, while they connect the line 22 to the branch 24 in the other switching position.
  • the switch 26 is firmly connected to the mirror housing 1. It can be designed as a microswitch, the switching processes of which are triggered by a cam 30.
  • This cam 30 is acted upon by a driver 31 which is firmly connected to the contact plate 5.
  • This driver 31 acts on the cam 30 in one pivot position of the mirror housing 1, while it relieves the cam 30 in the other pivot position of the mirror housing 1.
  • the relay 29 is connected via a feed line 32 to a light-sensitive cell 33 which emits an electrical voltage when a light beam strikes it. As soon as this voltage excites the relay 29, this connects the one branch 24 to the line 22. When the light on the photosensitive cell 33 ceases, the relay 29 drops out, so that the other branch 25 is now connected to the line 22.
  • the photosensitive cell 33 is fastened in an extension 34 which is connected to a lower edge 35 of the mirror housing 1 opposite the support arm 2.
  • a light channel 36 is formed, the longitudinal axis of which extends in the direction of the light beam dazzling the motor vehicle driver. This light beam falls through an aperture 37 into the light channel 36, at the end of which is opposite the aperture 37, the photosensitive cell 33 is arranged.
  • the aperture 37 can be closed with the aid of a cover cap 40.
  • This cap 40 is slidably mounted on a housing 41 forming the extension 34.
  • the housing 41 can be designed in the form of a cylinder, on the lateral surface of which the cover cap 40, which is likewise cylindrical, is slidably mounted.
  • This cover cap 40 has an inlet opening 42 corresponding to the diaphragm opening 37, which lies in a predetermined swivel position directly above the diaphragm opening 37.
  • the cover cap 40 With the aid of a handle 43, the cover cap 40 can be displaced with respect to the housing 41, so that the aperture opening 37 now lies below the cover cap 40 which defines the aperture opening 37 sealed light-tight.
  • This cover of the aperture 37 can be used in particular during the day to prevent daylight from entering the photosensitive cell 33.
  • the coupling 39 can expediently be connected to the support arm 2. In this way it is ensured that regardless of the respective setting of the mirror housing 1, the central axis of the light channel 36 always runs in a predetermined direction with respect to the longitudinal axis of the motor vehicle. This direction is predetermined by the direction of a light beam, which is emitted by a subsequent vehicle in the direction of the mirror housing 1.
  • the extension 34 it is possible to couple the extension 34 to a power switch.
  • the switch can be actuated by exerting pressure on the attachment 34 and the electric motor 12 can be switched on with the aid thereof.
  • displays 44, 45 can be mounted in the extension 34, which indicate the respective switching position of the mirror housing 1 to the driver of the motor vehicle.
  • These displays 44, 45 can be designed as light or sound indicators.
  • One of these two displays 44, 45 is located on one side of the diaphragm opening 37 in a transverse axis of the extension 34 extending parallel to the lower edge 35.
  • the entire electrical circuit necessary for controlling the electric motor 12 can also be accommodated in the attachment 34. It is particularly important to remember to design this circuit as a hybrid circuit.
  • Such a concentration of the circuit in the approach 34 also has the advantage that the approach 34 can be designed as an exchange part.
  • the extension 34 can also be replaced by inexperienced personnel at relatively low cost and the functionality of the rearview mirror can be restored.
  • the electrical circuit is spatially larger, so that it may not find any space in the approach.
  • the switch 26 is recently actuated, which cuts off the power supply via the branch 24 and creates a new connection between the line 22 and the branch 25.
  • the cam 18 remains in engagement with the driver 8, so that the Spiegelge housing 1 is held in its starting position as long as no further light beam falls on the photosensitive cell 33. Only when this is exposed again, the contact between the line 22 and the branch 25 is closed again by the relay 29, so that the electric motor 12 is now live and the mirror housing 1 can pivot via the drive 3.
  • the light channel 36 is closed with the cover cap 40. After dusk, the cover cap 40 is moved so that the aperture 37 is open for the incidence of a light beam.
  • the function of the electric motor 12 can also be triggered by the driver of the motor vehicle exerting pressure on the extension 34 designed as a switch. He thereby operates the switch so that the electric motor 12 is supplied with current.
