Abstract
Description
A DOOR HANDLE DEVICETechnical Field
[0001] The invention relates to a door handle device of a vehicle door, e.g. an electric door handle for a vehicle door.Background
[0002] Vehicle doors are equipped with door handle devices having a grip handle in order to comfortably open and close the vehicle doors. Electric door handle devices typically comprise a grip handle (= hand grip) , which can be gripped by the hand of the user. Typically, the grip handle may also be equipped with an unlocking function, such that the vehicle door can be unlocked for subsequent opening when an unlocking movement is performed. It is also known that door handles of this kind may be designed as electric door handles, i.e. they can be moved back and forth between an initial position or retracted position and a deployed position or an extended gripping position by means of an electric drive, in particular.
[0003] A disadvantage of the known solutions, in particular electric door handle devices, is that they are difficult to grip in the event of icing. This is in particular due to the fact that, when moving the electric handle out of the initial position and into the deployed position, a higher force is required in order to be able to blast away a crust of ice on the grip handle in the form of a layer of ice. To make this possible, the grip handle or the entire electric grip handle must be designed in an extremely solid and mechanically stable manner.Summary of the Invention
[0004] It is an object of the present invention to provide an improved door handle device of a vehicle door.
[0005] The object is achieved by a door handle device according to claim 1.
[0006] Preferred embodiments of the invention are given in the dependent claims.
[0007] The door handle device comprises at least a grip handle (also called operating handle) connected to a handle base so as to be able to move at least from an initial position to a deployed position. In the initial position, the grip handle is for example flush with the door. In the deployed position or gripping position, the grip handle protrudes from the door and can be gripped by the hand of a user of the door handle to unlock a door lock and / or open the door. The door handle device further comprises a link mechanism to actuate the grip handle, wherein the link mechanism comprises at least a first adjusting arm, a second adjusting arm, a coupling arm and an auxiliary arm, wherein the first adjusting arm and the second adjusting arm are rotatably connected to the grip handle, wherein the first adjusting arm is operatively coupled with a drive device and via the auxiliary arm with the coupling arm and the second adjusting arm is directly coupled with the coupling arm, and wherein the first adjusting arm, the second adjusting arm, the coupling arm and the auxiliary arm are configured and operatively coupled (also called effectively coupled) so that when the first adjusting arm is operated by the drive device the first adjusting arm operates the auxiliary arm and the auxiliary arm operates the coupling arm to operate the second adjusting arm so as to move the grip handle from the initial position into the deployed position.
[0008] According to the invention, in order to provide a simple adjusting movement in combination with a compact design of the door handle device as a compact assembling module, an auxiliary arm is provided to perform an effective functional adjustment movement and force transmission as well as to separate an opening movement and a closing movement of the grip handle. This should be understood to mean that the grip handle is moved back and forth in an alternating manner, i.e. multiple times, between at least two different functional positions, in particular between the initial position as one of an end positions and the deployed position as one of an intermediate position.
[0009] The core idea of the invention is therefore that the auxiliary mechanism provided, e.g. by the auxiliary arm and / or a reset arm, generates different adjusting movements of the grip handle to move forwards and backwards to provide e.g. a de-icing-mechanisms as well as a reset mechanism. Because, according to the invention, only a single connection is required between the drive device and the link mechanism (also called adjusting mechanism) , the door handle device is compact and simplified and can be easily adapted to different transmission forces.
[0010] According to an embodiment, the first adjusting arm, the second adjusting arm, the coupling arm and the auxiliary arm are configured and operatively joint-coupled so that the grip handle is linearly movable from the initial position into the deployed position with respect to a handle base, e.g. a housing or a carrier.
[0011] In the deployed position in which the first adjusting arm is stationary, the grip handle can be manually pivotable around a first pivot axis of the first adjusting arm from the deployed position into an opening position of the grip handle. In this opening position, the grip handle can be manually operated to unlock the door lock and / or to open the door.
[0012] According to another embodiment, the drive device comprises at least an actuator and an eccentric drive member driven by the actuator. For instance, the eccentric drive member comprises an outer eccentric cam. The eccentric drive member, in particular the outer eccentric cam, allows converting a rotation or rotary movement of the actuator into a linear movement of the grip handle.
[0013] In particular, the first adjusting device comprises at least one roller which is operatively coupled to the outer eccentric cam of the eccentric drive to operate the first adjusting device to linearly move the grip handle from the initial position to the deployed position.
[0014] Furthermore, a reset mechanism may be provided and configured as a de-icing mechanism (also called ice breakage mechanism) and / or retraction mechanism. The reset mechanism may comprise at least a reset rod and / or a return spring. The reset rod may be configured as an eccentric rod (also called eccentric connecting rod) . In particular, the eccentric rod may be rotationally connected to the eccentric drive. In a possible embodiment, the reset rod is coupled to the coupling arm and the drive device. Additionally, the centre of rotation of the eccentric rod may be offset eccentrically to the centre of rotation of the eccentric drive.
[0015] In a further embodiment, the reset rod may comprise a clearance. For example, the clearance is a long hole which extends along a longitudinal axis of the reset rod.
[0016] Furthermore, the auxiliary arm or the coupling arm may comprise a connecting element which is placed in the clearance of the reset rod to be contacted with an end of the clearance to pull the auxiliary arm or the coupling arm to reset the link mechanism. The connecting element may be configured as a convex part or a pin or bolt, e.g. a cylindrical bolt / pin.
[0017] Additionally, the grip handle may comprise a hole and the second adjusting arm comprises a connecting pin which is movably articulated within the hole of the grip handle.
[0018] Further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.Brief Description of the Drawings

[0037] Detailed Description of Preferred Embodiments
[0038] Figure 1 shows a schematic perspective view of a front side of a first embodiment of a door handle device 1 with a grip handle 2 in a hidden position or initial position 200.
[0039] The door handle device 1 comprises at least the grip handle 2 (also called operating handle) , a link mechanism 4 to actuate the grip handle 2 and a handle base 6, e.g. a housing or a carrier.
[0040] The handle base 6, e.g. the housing, of the door handle device 1 may be configured to be oriented, in particular arranged and possibly fastened, on a vehicle body outer part of a vehicle body (not shown) . The vehicle body outer part forms a part of the visible outer surface of the vehicle body. The vehicle can be, for example, a passenger car or a truck.
[0041] In the case of a vehicle such as a passenger car, three axes are as a rule defined in relation to the vehicle. The x-axis corresponds to the horizontal longitudinal direction of the vehicle, the y-axis corresponds to the horizontal transverse axis of the vehicle which lies perpendicularly with respect to the x-axis, and the z-axis corresponds to the vertical axis. In this way, an orthogonal three-dimensional coordinate system is defined by way of the x-axis, the y-axis and the z-axis. Apart from its movability between the initial position 200 (also called rest position, retracted position or first position) and a deployed position 202 (shown in figure 6, also called actuating position, extended gripping position or second position) , the grip handle 2 can be mounted on the handle base 6 in a play-free and positionally precise manner, in particular in the x-direction and the z-direction.
[0042] The door handle device 1 may be configured as an electric door handle device. The grip handle 2 (also called hand grip or operating handle) can be gripped by the hand of the user in the case, that the grip handle 2 has been moved into the deployed position 202 (shown in figure 6) . The grip handle 2 may also be equipped with an unlocking function, such that the vehicle door can be unlocked for subsequent opening when an unlocking movement is performed. The grip handle 2 is further designed to be electric, i.e. to be moved back and forth between the initial position 200 and the deployed position 202 by means of a drive device 8, e.g. an electric drive.
[0043] The handle base 6 comprises a number of mounting points 10 for attaching the door handle device 1 to the vehicle body (not shown) .
[0044] Figure 2 shows a schematic perspective view of a rear / inner side of the first embodiment of the door handle device 1.
[0045] The grip handle 2 is connected to the handle base 6 so as to be able to move at least from the initial position 200 (shown in figure 1) to the deployed position 202 (shown in figure 6) .
[0046] In the initial position 200, the grip handle 2 is for example flush with the door, in particular with the door body and / or the vehicle body. In the deployed position 202, the grip handle 2 protrudes from the door and can be gripped by the hand of a user of the door handle to unlock a door lock and / or open the door.
[0047] The door handle device 1 further comprises the link mechanism 4 to actuate the grip handle 2.
[0048] For example, the link mechanism 4 may comprise at least a first adjusting arm 4.1, a second adjusting arm 4.2, at least one coupling arm 4.3 and an auxiliary arm 4.4.
[0049] The first adjusting arm 4.1 and the second adjusting arm 4.2 are rotatably connected with the grip handle 2.
[0050] The first adjusting arm 4.1 is operatively coupled to the drive device 8 and via the auxiliary arm 4.4 to the coupling arm 4.3. The first adjusting arm 4.1 is also called drive arm. The second adjusting arm 4.2 is directly coupled with the coupling arm 4.3.
[0051] The first adjusting arm 4.1, the second adjusting arm 4.2, the coupling arm 4.3 and the auxiliary arm 4.4 are configured and operatively coupled so that when the first adjusting arm 4.1 is operated by the drive device 8 the first adjusting arm 4.1 operates the auxiliary arm 4.4 and the coupling arm 4.3 to operate the second adjusting arm 4.2 so as to move the gripe handle 2 from the initial position 200 into the deployed position 202.
[0052] Figure 3 shows a schematic perspective view of the rear side of the first embodiment with the grip handle 2 in the initial position 200.
[0053] The drive device 8 may comprise at least an actuator 8.1, e.g. an electric motor.
[0054] The drive device 8 may further comprise an eccentric drive member 8.2 driven by the actuator 8.1. For instance, the eccentric drive member 8.2 comprises an outer eccentric cam 8.21 (better shown in figure 6 or 11) .
[0055] Additionally, the first adjusting device 4.1 comprises at least one roller 4.11 (better shown in figure 6) which is operatively coupled to the outer eccentric cam 8.21 of the eccentric drive member 8.2 to operate the first adjusting device 4.1 to linearly move the grip handle 2 from the initial position 200 to the deployed position 202.
[0056] Furthermore, a reset mechanism 10 is provided and configured as a de-icing mechanism (also called ice breakage mechanism) and / or retraction mechanism. The reset mechanism 10 may comprise at least a reset rod 10.1 and / or a return spring (not shown) . The reset rod 10.1 may be configured as an eccentric rod 10.2 (also called eccentric connecting rod) .
[0057] In particular, the eccentric rod 10.2 may be rotationally connected to the eccentric drive member 8.2. In a possible embodiment, the reset rod 10.1, e.g. the eccentric rod 10.2, is coupled with the coupling arm 4.3 and the drive device 8, in particular with the eccentric drive member 8.2. Additionally, the centre of rotation of the eccentric rod 10.2 may be offset eccentrically to the centre of rotation of the eccentric drive member 8.2.
[0058] In the present embodiment, the door handle device 1 comprises two coupling arms 4.3.
[0059] The first adjusting arm 4.1 is indirectly coupled to at least one of the coupling arms 4.3 via the auxiliary arm 4.4. The other coupling arm 4.3 is directly coupled to the reset rod 10.1 in a first articulation point 300. The second adjusting arm 4.2 is directly coupled, in particular articulated, to at least one of the coupling arms 4.3 or to both of the coupling arms 4.3 in a second articulation point 302.
[0060] The auxiliary arm 4.4 is directly coupled, e.g. articulated, to one of the coupling arms 4.3 in a third articulation point 303.
[0061] Each of the coupling arms 4.3 is directly connected, e.g. articulated, with the grip handle 2 in corresponding fourth articulation points 304.
[0062] Figure 4 shows a schematic side view of the first embodiment with the grip handle 2 in the hidden or initial position 200. Figure 5 shows a schematic reverse side view of the first embodiment of the door handle device 1 according to figure 4.
[0063] The eccentric drive member 8.2, in particular the outer eccentric cam 8.21, allows converting a rotation or rotary movement 204 of the actuator 8.1 into a linear movement 206 of the grip handle 2.
[0064] In particular, the auxiliary arm 4.4 is coaxially disposed on the first adjusting arm 4.1 (shown in detail in figure 10) . The auxiliary arm 4.4 is immediately adjacent to the first adjusting arm 4.1.
[0065] The reset mechanism 10 may be connected to the auxiliary arm 4.4 and / or at least one of the coupling arms 4.3. The eccentric rod 10.2 is rotationally connected to the drive device 8, e.g. to the actuator 8.1 and / or the eccentric drive member 8.2, e.g. by a drive link 10.3. A first centre of the rotation 305 of the eccentric rod 10.2 is eccentrically offset to a second centre of rotation 306 of the eccentric drive member 8.2.
[0066] The eccentric rod 10.2 (also called eccentric linkage) may be provided between the eccentric drive member 8.2 and the auxiliary arm 4.4
[0067] During a reset process, in particular controlled and driven by the eccentric drive member 8.2, the eccentric rod 10.2 pulls the auxiliary arm 4.4 and drives the at least one of the coupling arms 4.3 to reset.
[0068] Additionally, the reset mechanism 10 may comprise at least one reset spring 14, e.g. a reset torsion spring, to provide a rotational connection of the first adjusting arm 4.1 and the second adjusting arm 4.2 with respect to the handle base 6 (shown in figure 1) .
[0069] In particular, during the reset process, the reset rod 10.1 and the reset spring / s 14 jointly and / or separately drive the grip handle 2 back to the deployed position 202 and / or the initial position 200. For instance, reset rod 10.1 and the reset spring / s 14 jointly set the grip handle 2 back to the deployed position 202. Subsequently, the reset spring / s 14 separately set the grip handle 2 back to the initial position 200.
[0070] Furthermore, the reset rod 10.1, in particular the eccentric rod 10.2, may comprise a clearance 10.4. For example, the clearance 10.4 is a long hole which extends along a longitudinal axis of the reset rod 10.1.
[0071] The auxiliary arm 4.4 or at least one of the coupling arms 4.3 may comprise a connecting element 12 which is placed in the clearance 10.4 of the reset rod 10.1 to be contacted with an end of the clearance 10.4 to pull the auxiliary arm 4.4 or the coupling arm 4.3 to reset the link mechanism 4. The connecting element 12 may be configured as a convex part or a pin or bolt, e.g. a cylindrical bolt / pin, of the auxiliary arm 4.4 or the coupling arm 4.3 concerned.
[0072] Figure 6 shows a schematic side view of the first embodiment with the grip handle 2 in the deployed position 202. Figure 7 shows a schematic reverse side view of the door handle device 1 according to figure 6.
[0073] The drive device 8 comprises the actuator 8.1, e.g. an electric motor, and the eccentric drive member 8.2., e.g. a cam disc. The eccentric drive member 8.2 may be connected to an output end of actuator 8.1, e.g. to a drive pinion of the actuator 8.1. The eccentric drive member 8.2 may be synchronously rotated by the actuator 8.1.
[0074] The first adjusting arm 4.1 comprises the roller 4.11. The roller 4.11 is rotationally mounted at the first adjusting arm 4.1, e.g. by a rotation bearing. The eccentric drive member 8.2 is operatively coupled to the roller 4.11.
[0075] During a drive process, the eccentric drive member 8.2 touches and pushes the first adjusting arm 4.1 to pivot according to the rotational movement 204 to linearly move the grip handle 2 according to the linear movement 206 from the initial position 200 (shown in figures 1 and 5) to the deployed position 202. In particular, the first adjusting arm 4.1 is operated by the drive device 8. The first adjusting arm 4.1 operates the auxiliary arm 4.4. The auxiliary arm 4.4 subsequently operates the coupling arm 4.3 to operate the second adjusting arm 4.2 so as to move the gripe handle 2 from the initial position 200 into the deployed position 202.
[0076] Figure 8 shows a schematic side view of the first embodiment with the grip handle 2 in an opening position 203. Figure 9 shows a schematic reverse side view of the first embodiment according to figure 8.
[0077] In the deployed position 202 (shown in figures 6 and 7) the first adjusting arm 4.1 may be fixed stationary, the grip handle 2 may then be manually pivotable around a first pivot axis 307 of the first adjusting arm 4.1 from the deployed position 202 into the opening position 203 (manual operation) according to a pivot movement 208. During this opening process manually operated by the hand of a user, the second adjusting arm 4.2 is being pulled outwards.
[0078] The eccentric drive member 8.2 further comprises a drive pin 8.24, e.g. a wheel, to operatively connect it to the output end of the actuator 8.1.
[0079] Figure 10 shows a schematic perspective view of the first adjusting arm 4.1 and the auxiliary arm 4.4 which is coaxially coupled to the first adjusting arm 4.1 at an auxiliary articulated point 301. The first adjusting arm 4.1 may be L-shaped or J-shaped. On an opposite end of the first adjusting arm 4.1, the first adjusting arm 4.1 comprises a respective bearing for the fourth articulated point 304 to jointly couple it to the grip handle 2.
[0080] The auxiliary arm 4.4 comprises a respective bearing to coaxially couple to at least one of the coupling arms 4.1 at the third articulated point 303. The auxiliary arm 4.4 may be I-shaped or U-shaped.
[0081] Figure 11 shows a schematic perspective view of an eccentric drive member 8.2.
[0082] The eccentric drive member 8.2 comprises the eccentric cam 8.21. The eccentric cam 8.21 comprises for example a flat surface 8.22 and a cam surface 8.23. The flat surface 8.22 is in contact with the roller 4.11 (shown in figure 7) when the grip handle 2 is in the initial position 200 (shown in figure 1) . During the deploy movement, in particular rotational movement 204, the cam surface 8.23 is in contact with the roller 4.11 to move the first adjusting arm 4.1 outwards, in particular to rotate it. The eccentric cam 8.21 may comprise a transition surface, in particular a smooth transition surface, between the flat surface 8.22 and the cam surface 8.23.
[0083] On an opposite end to the drive pin 8.24, the drive link 10.3 may be coupled to the eccentric drive member 8.2. The eccentric drive member 8.2 and the eccentric rod 10.2 of the reset mechanism 10 (shown in figure 4) may be operatively connected with each other by this drive link 10.3.
[0084] Figure 12 shows a schematic sectional view of the door handle device 1 in a coupling area of the second adjusting arm 4.2 and the grip handle 2 at their respective fourth articulated point 304. Additionally, the grip handle 2 may comprise a hole 2.1 at this fourth articulated point 304. The second adjusting arm 4.2 comprises a connecting pin 4.21 which is movably articulated within the hole 2.1 of the grip handle 2 to provide some play.
[0085] Figure 13 shows a schematic diagram of the different positions of the grip handle 2, e.g. the initial position 200, the deployed position 202 and the opening position 203 and the respective linear movement 206 from the initial position 200 to the deployed position 202 operated by the drive device 8 and the manual pivot movement 208 from the deployed position 202 to the opening position 203 operated by the hand of a user.
[0086] Figure 14 shows a schematic side view of a second embodiment of a door handle device 100 with a grip handle 102 in the initial position 200. The door handle device 100 differs only in an alternative auxiliary arm 104.4.
[0087] The door handle device 100 shows a simple link mechanism 104 which comprises as the auxiliary arm 104.4 a lever which is directly articulated on at least one of the coupling rods 104.3. The first adjusting arm 104.1 operates the auxiliary arm 104.4. A transmission force between the first adjusting arm 104.1 and the auxiliary arm 104.4 may be limited by the length of the auxiliary arm 104.4.
[0088] Figure 15 shows a schematic side view of the door handle device 100 with the grip handle 102 in the deployed position 202 after the linear movement 206 of the grip handle 102 due to the rotational movement 204 of the first adjusting arm 104.1. The first adjusting arm 104.1 comprises the roller 104.11 to get in an operative connection with the drive device 8 to rotate as described above for the first embodiment.
[0089] Figure 16 shows a schematic side view of the second embodiment of the door handle device 100 with some play for the auxiliary arm 104.4 to manually move the grip handle 102 into the opening position 203 according to the pivot movement 208 as shown in figure 16.
