Definitions
- This invention relates to vehicle mirror assemblies, vehicle mirror actuators and in particular to vehicle mirror actuators powered by small electric motors.
- One particular application where the torque initially required is high is in power foldable vehicle mirror heads.
- wing mirrors External rear view mirrors (wing mirrors) fitted to modern cars (automobiles) often form the widest part of the vehicle.
- the heads of these mirrors are usually designed to rotate about a substantially vertical pivot both forwards and backwards.
- a detent mechanism is provided to hold the mirror head in its operable position.
- Some vehicles are fitted with "power fold” or “park” mechanisms which fold the wing mirrors from their deployed position inwards to a folded position when the vehicle is parked. This effectively reduces the width of the vehicle and reduces the risk of impact or interference from passing pedestrians or other vehicles.
- Park mechanisms within wing mirrors generally include small 12 volt DC electric motors which drive the mirror head through a reduction gear train.
- the designer in selecting the appropriate motor and gear train for park mechanism, the designer must size the motor such that a sufficient torque is produced at 9 volts to overcome the resistance of the detent mechanism and ice or other accretions that may act to resist movement.
- the motor must also be able to survive a constant 16 volts.
- the designer is limited in the reduction ratio by both the reduction in angular speed (caused by high ratios) and hence the time taken to park with the mirror mechanism and practical issues such as fitting a drive train with a high gear reduction within a small space within the mirror assembly.
- Park mechanism motors are usually required to operated from the vehicle's electrical system having a supply voltage that can range from 9.0 to 16.0 volts. Such a wide voltage range , if supplied directly to drive motors, will result in a wide variation of shaft output torques and speeds.
- a vehicle external mirror assembly comprising: a base mountable to a vehicle; a head pivotally mounted to the base, the head supporting a mirror; and a park mechanism for rotating the head with respect to the base from a deployed position to a parked position in which the outermost portion of the head is positioned closer to the vehicle, the park mechanism comprising a motor having an output shaft connected to a reduction gear train, characterised in that the park mechanism is located within the base.
- the motor is a DC motor and the assembly further comprises a controller for controlling the voltage supplied to the motor, wherein the controller supplies power to the motor at a voltage above its nominal continuous voltage rating for short time periods so as to produce high torque without damage to the motor over the park mechanism's design life.
- the gear train has a variable gearing ratio, whereby when the motor drives the output shaft at a substantially constant angular velocity, the angular velocity of the head with respect to the base varies.
- the gear train comprises a variable ratio epicyclic gear assembly.
- the epicyclic gear assembly comprises: a sun gear having a central axis of rotation; a planetary gear engaged by the sun gear; a ring gear engaged by the planetary gear; a carrier mounted for rotation about a carrier axis substantially co-axial with the axis of the sun gear; and a means for connecting the planetary gear to the carrier at a location on the planetary gear offset from the geometric center of the planetary gear, so as to allow the planetary gear to rotate with respect to the carrier, wherein, in use, the ratio of angular velocity of the sun gear to the angular velocity of the carrier varies with the angular position of the carrier.
- an epicyclic gear assembly comprising: a sun gear having a central axis of rotation; a planetary gear engaged by the sun gear; a ring gear engaged by the planetary gear; a carrier mounted for rotation about a carrier axis substantially co-axial with the axis of the sun gear; and a means for connecting the planetary gear to the carrier at a location on the planetary gear offset from the geometric center of the planetary gear, so as to allow the planetary gear to rotate with respect to the carrier, wherein, in use, the ratio of angular velocity of the sun gear to the angular velocity of the carrier varies with the angular position of the carrier.
- a method of supplying power to a drive motor for a vehicle mirror comprising the steps of: supplying a first voltage to the drive motor for a first time period; and supplying a second voltage to the motor for a second time period, subsequent to the first time period, the second voltage being lower than the first voltage.
- Embodiments of the invention according the second aspect of the invention provide a gear train in which as the sun gear rotates, the shaft of the planet gear moves in and out relative to the center of the sun gear. This changes the effective gear ratio of the gear train (the ratio of the sun gear to the carrier). The level of change is governed by the degree of eccentricity of the planet shaft with respect to its geometric center and the ratio of the number of teeth on the ring gear to the number of teeth on the planet gear. With this varied gear ratio the output speed and torque at particular angular positions is varied and can be tailored to suit a particular application.

- Figures 10 and 11 show the vehicle external mirror of Figures 7 and 8 respectively with an alternative mounting of the epicyclic gear train shown in Figures 2, 3, 4 and 6;
- Figure 12 shows a schematic block diagram of a motor controller according to the invention
- Figure 13 shows a schematic block diagram of an alternative motor controller.
- a vehicle external mirror assembly is shown.
- the assembly comprises a base 9 mounted to a vehicle (not shown), a head 8, pivotally mounted to the base and a park mechanism 100 of reduced size for rotating the head 9 with respect to the base 8 from a deployed position to a parked position in which the outer most portion of the head 9 is positioned closer to the vehicle.
- the park mechanism 100 comprises a motor 90 having an output shaft 92 connected to a reduction gear train 95.
- the reduction gear train includes a worm gear 96.
- the park mechanism 100 can be used to replace much of the structure of the base 20 thereby reducing the weight of the mirror assembly 10 and simplifying its design. Having the park mechanism 100 located within the base 20, as opposed to within the head 30, moves the center of gravity of the mirror assembly inwards. Also the pivot 50 no longer carries the load of the park mechanism 100.
- the park mechanism 100 is of reduced size because of the use of a voltage controller in association with an undersized motor 90. The reduced size of the park mechanism 100 allows it to be located in the mirror base 8.
- the undersized motor 90 within the first embodiment of the invention is a 2.0 nominal continuous rated voltage DC electric motor (for instance a Mabuchi RF- 4LO WA-13185 D/V5.9 DD450X13 motor).
- the 12 volt power supply 130 from the vehicle supplies power to 4.0 volt and 7.0 volt power supplies 132 and 134.
- a voltage selection switch 136 supplies power to the motor 90 within park mechanism 100 at either 7.0 volts or 4.0 volts.
- Switch 140 is actuated by the vehicle driver to operate park mechanism 100. Once the switch 140 has been actuated, the timer 138 starts and sends an initial signal to the voltage selection switch allowing 7.0 volts to be supplied and then after a fixed time, (for instance 0.6 seconds) has elapsed, the timer switches the voltage to 4.0 volts.
- FIG. 13 An alternative assembly is shown in Figure 13. With this assembly, the 4.0 volt power supply 132, the 7.0 volt power supply 134 and the voltage selection switch 136 are replaced by a single motor driver 137.
- the motor driver 137 drives the motor within park mechanism 100 at differing voltages depending on the signal from the micro controller 139. Different average voltages are achieved, using pulse width modulation.
- the motor is initially supplied with a voltage Ni of 7.0 volts for approximately 0.6 of a second. At this stage no over current protection is provided. After 0.6 seconds have elapsed, a second voltage N 2 of 4.0 volts is provided at the same time as over current protection.
- the over current protection switches the supply voltage off when the current exceeds 220mA. Arrow 120 on Figure 4 shows the voltage dropping as the over current protection comes into effect.
- the above described method results in the motor providing a high torque initially to overcome the resistance of the detent mechanism and ice or other accretions that may act to resist movement of the mirror head with respect to the mirror bracket.
- the voltage is reduced. This is appropriate since less torque is required after the initial rotation to continue to rotate the mirror head through to its parked position.
- the current will increase due to the motor stalling and the over current protection switches the supply voltage off.
- the polarity of the voltage applied to the motor is reversed, again with an initial voltage of 7.0 volts.
- This provides high torque to overcome park detents and any accretions that may have built up.
- the voltage against time may be the same as that described above (with reference to Figure 12 or 13) for mirror head parking (except the voltage is reversed). Alternatively a different voltage against time regime may be applied for redeployment.
- the method of the invention allows manufacture of very small park mechanisms and therefore allows the mechanism to be fitted into a vehicle mirror bracket (as opposed to a mirror head).
- Application of the invention can provide other advantages such as reduced weight, less conductors required to supply the mirror head, increased styling freedom, the ability to move weight closer to the vehicle reducing vibration problems and reduced power requirements.
- use of the first embodiment of the invention simplifies the motor and gear train selection and design by providing known voltages and removing the usual variability in voltages supplied through the vehicle's electrical system.
- the park mechanism 100 is of reduced size because of the use of a variable ratio gear train within the park mechanism.
- the use of a variable ratio gear train allows a smaller motor 90 to be used than would otherwise be the case.
- variable ratio gear train the form of a epicyclic gear train is shown.
- the epicyclic gear train shown comprises a central sun gear 15, three planetary gears 20 each engaged by the sun gear, a ring gear 50 engaged by the planetary gears and a carrier 60 (shown in Figure 4) mounted for rotation about an axis substantially coaxial with the axis of the sun gear.
- Each planet gear 20 has a shaft 21 extending from an area on the surface of the planetary gear 20 at a location off set from its geometric center.
- the carrier 60 has three radial slots 62 as shown in Figure 3. These slots 62 connect the planetary gears 20 to the carrier 60.
- Each planet shaft 21 is free to rotate but is compelled to oscillate in a radial direction with respect to the sun gear by its corresponding radial slot 62 within the carrier 60.
- the shafts 21 of the planet gears 20 move in and out relative to the center of the sun gear 15. This changes the effective gear ratio between the sun gear and the carrier.
- the level of change is governed by the degree of eccentricity of the planet shafts 21 with respect to the geometric centers of their corresponding planet gears.
- the output speed and torque is also varied and can be tailored to suit a particular application.
- Figure 4 shows only one carrier 60, however two carrier discs may be used, one above and one below the assembled sun gear, planetary gears and ring gear.
- a slider having a bearing surface adapted to reciprocate within slot 62 and a bearing to allow free rotation of shafts 21, will be provided.
- the means for connecting a planetary gear to the carrier includes an arm 65' having a proximal end 66' pivotally mounted to the carrier 60' and a distal end 67' rotatably mounted to its planetary gear 20' at a location on the surface of planetary gear 20' off set from its geometric center.
- the sun gear 15' rotates, the planetary gear shafts 21' move in and out with respect to the center of the sun gear changing the effect gear ratio.
- the level of change is governed by the degree of eccentricity of the planets shafts 21'.
- FIG. 6 shows a modified planetary gear 20 having upper and lower bearing surfaces 23 and 24 separated by the gear teeth region 25. These bearing surfaces, in conjunction with similar surfaces on the sun and ring gears, limit the radial movement of the gears with respect to each other.
- Figures 7 and 8 the epicyclic gear train of Figures 2, 3 and 4 is shown mounted within a vehicle external mirror.
- Figures 7 and 8 both show a mirror head 8 pivotally mounted with respect to a mirror base 9 and an epicyclic gear assembly 10 mounted within the mirror base 9 and mirror head 8.
- the mirror head 8 is shown moving away from its deployed (in use) position. Arrow 7 indicates the direction of movement from the deployed position to a "parked" position shown in Figure 8.
- the extent of angular rotation of the mirror head 8 about the sun gear 15 required in particular applications will vary. Typically for a drivers side mirror, the degree of rotation required will be around 70° and on the passenger side mirror will be around 60°.
- the mirror head 8 shown in Figures 7 and 8 contains a motor (such as the motor shown in Figure la) which drives the sun gear 15 through a conventional worm reduction gear train (with a reduction ratio of approximately 700:1). Also fixed with respect to the head is the ring gear 50.
- the carrier 60 (for clarity, not shown in Figure 7 and 8) is mounted to the base 9. Hence the planetary gear shafts 21 are constrained with respect to the base 9 (although some movement is allowed within the constraints of slot 62 of the carrier 60). Therefore as the sun gear 15 rotates in an anticlockwise direction, as shown in Figure 7, the mirror head 8 moves in a clockwise direction.
- Position indicators 16 (showing the angular position of the sun gear) and 51 (showing the angular position of the ring gear 50) are marked on Figures 7 and 8 to show respective positions of these gears from the deployed position of Figure 7 to the parked position of Figure 8.
- Figure 9 shows graphically the change in the ratio of angular movement of the sun gear with respect of the angular movement of the carrier (and hence the mirror head) as the carrier angular position varies.
- This graph clearly shows that there is a substantial variation in gear ratios from the mirror head position shown in Figure 7 and the mirror head position shown in Figure 8.
- the solid squares within the graph of Figure 9 represent data points for the "slot" arrangement shown in Figures 2 to 4 whereas the hollow diamonds within the graph represent data points for the "radial arm” arrangement shown in Figure 5.
- the maximum reduction ratio (sun to carrier) is at the position shown at 81. At this particular angular position, a reduction ratio of approximately 5.3 is achieved. This ratio will be appropriate for the angular position at which the mirror head 8 is in its deployed position. Because of the high reduction ratio at this point, maximum torque is developed to allow the head 8 to rotate through a detent mechanism and to breakaway any ice that may have formed between the mirror head 8 and the mirror base 9. As the mirror head 8 rotates in the direction shown by arrow 7 in Figure 7, the torque gradually reduces while the speed increases to a point shown on the graph of Figure 9 marked 85. At this point 85, torque is at a minimum, the reduction ratio having fallen to approximately 1.5, and the speed is at a maximum.
- an angular delay zone can be introduced between the carrier and the head in combination with a velocity ratio that provides a non-integer phase, such as a half-phase or a five-thirds phase, so that angular movement always starts at maximum torque (minimum velocity) and ends at minimum torque (maximum velocity).
- a velocity ratio that provides a non-integer phase, such as a half-phase or a five-thirds phase, so that angular movement always starts at maximum torque (minimum velocity) and ends at minimum torque (maximum velocity).
- Figures 10 and 11 show an alternative arrangement to that shown in Figures 7 and 8 in which the carrier 60 is mounted to the mirror head 8 and the ring gear 50 is mounted to the base 9.
- the sun gear 15 rotates in an anti- clockwise direction, as shown in Figure 10, the mirror head 8 moves in a clockwise direction.
- Position indicators 16 (showing the angular position of the sun gear) and 61 (showing the angular position of the carrier 60) are marked on Figures 10 and 11 to show respective positions of these components from the deployed position of Figure 10 to the parked position of Figure 11.
- the second embodiment of the invention allows "optimising" of the torque and speed at particular angles of the output shaft.
- An advantage of this is that it enables the selection of a lower power motor (and hence smaller motor) than would usually be required for a mirror parking motor-gearbox assembly.
- the park mechanism 100 can be used to replace much of the structure of the base 20 thereby reducing the weight of the mirror assembly 10 and simplifying its design. Having the park mechanism 100 located within the base 20, as opposed to within the head 30, moves the center of gravity of the mirror assembly inwards. Also the pivot 50 no longer carries the load of the park mechanism 100.
- mirror base mounting bracket

- electronic sensors such as proximity sensors to determine if the vehicle mirror is close to an obstruction

- Other various electronic equipment may be incorporated into the mirror base (mounting bracket) such as lights used to light the area around the vehicle, or lights that may be controlled from within the vehicle that enable the light to be moved so as to provide directional lighting.
