This application claims priority to German Application No. DE 10 2022 109 075.2, filed on Apr. 13, 2022, the entirety of which is incorporated herein by reference.
The present disclosure relates to a memory module for use with an actuator of a rear view device for a vehicle. Furthermore, the present disclosure refers to an actuator with such a memory module, a rear view device with such an actuator, a vehicle with such a rear view device as well as a method for manufacturing such memory module.
A rear view device, such as an external mirror of a vehicle, may provide the driver with a lateral or rear view of the vehicle. In a specific situation during driving, for example, a situation such as parking, a driver needs to secure a view not only in the lateral or rear direction of the vehicle but also in the downward direction of the vehicle. In addition, it is necessary to provide various viewing angles depending on the driver.
In order to provide a view of the vehicle in various directions, a rear view element (e.g. a mirror element, a display unit or a camera device) attached to the rear view device may be pivoted. The rear view device may comprise an actuator that operates to pivot the rear view element.
The driving mechanism for driving the actuator may comprise a driving motor and a gear structure operated by receiving power from the driving motor.
After the pivoting, in order to return the rear view of the rear view device to the original state, the actuator may comprise a memory module for obtaining, storing, providing and controlling an angle of inclination of the rear view element. In order to be connected to the driving mechanism, the memory module is generally configured with small parts. Thus, manufacturing such small memory modules is complex and at the same time the complexity of memory modules increase their size and lowers the efficiency of the manufacturing process.
In view of the aforementioned drawbacks and other inherent in the existing state of the art, it is an object of the present disclosure to further develop the memory modules to overcome at least some of these drawbacks. In particular it is an object to provide a miniaturized memory module, an actuator with such a memory module and a method for manufacturing the same.
This object is accomplished according to the present disclosure by the features set forth in the claims.

The pivot angle can be determined by any value identifying the pivot angle (e.g. a position of a gear) and thus, can be determined directly or indirectly by e.g. sensing the status of a gear element. In some situation two pivot angles may have to be determined e.g. for the left/right and up/down direction. Furthermore, several pivot angles may be stored in accordance to driving situation or stored configurations e.g. relating to specific drivers.
In an embodiment, the memory module may be further adapted to control the actuator for adjusting the pivot position of the rear view device and/or the at least one rear view element; read-out the at least one stored pivot angle; and/or transmit the at least one stored pivot angle, preferably to a control unit controlling the actuator. In a further embodiment, at least one pivot angle may be transmitted to a control unit controlling the actuator. The controlling function may be implemented via an electric motor.

For example, the circuit board 206 may be arranged on the support member 204, and the memory gear 202 may be adapted to cover at least a part of the circuit board 206.
In an embodiment of the present disclosure, the support member 204 may comprise an insertion part 205 and a forming part 232. The insertion part 205 may protrude from at least a part of the support member 204 and may be adapted to pass through at least a part of the circuit board 206 and the memory gear 202. The forming part 232 may be formed in an edge region of the insertion part 205. The forming part 232 may be formed by welding. The forming part 232 may be formed to have a larger diameter than the first hole 211, thereby preventing the insertion part 205 from being separated from the first hole 211. For example, in a state in which the insertion part 205 is inserted into the first hole 211, the end of the insertion part 205 made of metal or polymer material is processed at high temperature and the forming part 232 may be formed. The forming part 232 may rotate under the support area 216. In an embodiment of the present disclosure, the width of the forming part 232 may be greater than the width of the insertion part 205.
