Description

Striker drive unit for car door lock mechanism or the like

The present invention relates to a striker drive unit (Schliesskeil-Antriebsbaugruppe) for a door lock mechanism or the like of an automobile, having the features of the higher concept of claim 1.

The door lock mechanism or the like of a motor vehicle has been known from the past, which is provided with a motor aiding device for enhancing the operation comfort. Motor visibility aids are also widespread in locks for rear covers and rear doors, and motor sight aids are increasingly being used in the side doors of automobiles.

In a first kind of door lock mechanism or the like of a motor vehicle, a motor aiding device is arranged in a latch, and a striker is fixedly arranged in a structural member, for example, a B column or a C column, which is located opposite to the vehicle body side. It works as a support.

The motor aiding apparatus of this kind is excellent, but structurally has operational technical problems. In order to solve these problems, a second kind of automobile door lock mechanism or the like is known, in which the motor aiding device is arranged on the striker and not already on the latch. This gives the striker drive unit a suitable structural member of the vehicle body, for example column B or column C. The non-moving structural member of the vehicle body, for example the striker drive unit in column B, has several advantages. The operating mechanism and the centralized locking mechanism in the door lock mechanism or the like in the door of the vehicle are independent from the drive of the visual aid. The driving device of the visual aid is fixed to the vehicle body and does not lose high acceleration when the door of the vehicle is closed. The structural bypass of the drive motor of the drive, which is necessary for the safety of the door opening in an emergency, is naturally realized, and the control mechanism for manual operation of the latch is still effective, and the striker is moved to the striker position moved by the drive. Regardless, they are exactly the same.

The teachings of the present invention start from a striker drive unit having a striker support arranged in a linearly movable manner (US Pat. No. 4,707,007; 49,984). This striker drive unit can be used as a side door, a rear door, a rear cover, a trunk cover, an engine hood or the like.

In the known striker drive unit, the striker is first detachable to the striker support and is attached interchangeably. The striker is ie screwed to the striker support. Thus, the striker support can be used for all-purposes, such as those suitable for each type of automobile, for example, a desired striker is attached to the striker support, for example, a wedge shaped striker, a striker configured as a curved member, a striker configured as a pin, and the like. Because you can.

In the known striker drive unit, the striker support is movably disposed in the casing, and the casing and the drive are fixedly coupled. The drive device includes an electric drive motor and a reduction device configured as a gear device. Alternatively, other drive motors (hydraulic, pneumatic), other electric gears (warm gear devices), and direct drive devices (hydraulic cylinders with racks) are mentioned. In this way, the unit itself which consists of a casing and a drive device is provided with the fixing means for fixing to the desired vehicle body structure part. This fastening means is a fastening screw in the known art, i.e., the unit is fixed to the vehicle body like the previous pure striker without the drive unit.

In the known striker drive unit, the striker supporter can be driven via the eccentric member, and the eccentric member is coupled into the receiving portion of the striker supporter. A force transmission surface is formed at the edge of the receiving portion in the striker support, on which the eccentric member abuts the transmission force with slight friction. The numerical value of the receiving portion is adapted to the dimension of the eccentric member, so that the striker support follows the angular motion of the eccentric member.

In the above-mentioned known striker drive unit having a striker support arranged in a linearly movable manner, which is the starting point of the present invention, the striker cannot be escaped even when the vehicle door is closed with a strong force and the eccentric member is loaded. . When the eccentric member is in the open position (front position) and the drive fails, the striker is blocked in the open position (front position). In this case, the door of the car is not limited to the prerast position, which may be allowed for a certain time in safety technology, but it is not comfortable.

The behavior of the striker drive unit must also correspond sufficiently to the behavior of a striker without a drive device, which is fixedly screwed to the vehicle body structure, excluding the linear mobility of the striker support.

The problem of the present invention is that a striker drive unit having a striker support unit arranged to be movable in the above known linear shape can be reliably fixed in an automobile door even in the event of a drive failure, and the entire striker drive unit is as fixed as possible. It is configured to behave like a striker attached to and developed.

The said subject is solved by having the characteristic of the characteristic part of Claim 1 in the striker drive unit which has the characteristic of the higher concept of Claim 1.

According to the present invention, the striker supporter follows the drive motion of the drive member, but some of the motion of the striker support body introduced from the striker is constituted by a structure which does not act on the drive member. Therefore, when the drive member, in particular the eccentric member, is in the open position (front position), the door of the vehicle can be closed without directly applying force to the drive member, in particular the eccentric member.

The configuration of the drive member as the eccentric member is excellent in the embodiment according to claim 2, and shows a particularly simple implementation of one-sided free rolling between the eccentric member and the striker support.

It is particularly advantageous that the striker support according to claim 3 has a spring member which loads the striker support in the open direction with spring force. This is also because this obtains a certain position of the striker support realized by the spring force relative to the drive member, and the force upon closing the door to the striker support is (partly) absorbed by the spring member.

Also of particular importance is the configuration of claim 4. By means of a manual adjustment in combination with an unobstructed striker support, the striker support is moved from the start with the striker to the correct position (mainly correct position) in the event of an emergency, i.e. in the event of a failure of the drive, which is also achieved here do. Soon the door is simply relatively strong and must be closed under force because it lacks a motor aid to move the striker support. However, when the door is closed with great force, the door finally reaches the corrective device (mainly correct position) as in normal time. Thus, the striker is replaced by a floating striker that cannot be moved by the motor by the action of a manual control device in an emergency.

Excellent configuration and development for this embodiment is the subject of claims 5-7.

Claims 8 and 9 are important for the reception of forces and for optimum mobility of the striker support.

It has now been described that the emergency behavior of the striker drive unit corresponds to a fixedly arranged striker. This behavior is improved with respect to certain areas in other ways by the present invention. According to Claim 10, the adjustability of the support part of a striker support body makes the striker itself float as much as possible in a door-locking state, and as a result, the noise on the run is reduced as much as possible. Embodiments of this control are the subject matter of claims 11-13.

The striker drive unit as a whole would also have to be statically adjustable with respect to the locks in the car door, in principle like a normal, fixedly arranged striker. This is described in claim 14.

Embodiment of the Invention

The teachings of the present invention are directed to a striker drive for an automobile door lock mechanism or other mechanism in a structural member of a vehicle body, for example a rear door, a rear plate, a trunk cover, an engine hood, a lock behind a chair or the like. It is about.

1, 2 and 3 should be considered together with respect to the first embodiment.

The drive motor 1 is shown. The drive motor is usually an electric drive motor. As described in all of the specification, basically, a pneumatic or hydraulic drive motor is also contemplated. The transmission device 2 is connected after the drive motor 1, which together form the drive devices 1, 2. The transmission device 2 drives the striker support 3 and drives with a linear movement. The linear motion is shown by two arrows in FIG. In this example, since the striker 4 of the striker support 3 is in the gazing-correcting position, the striker can move the inside of the long hole 5 shown from this position to the left-right exhibition position, and a return arrow is shown. .

The fixing screw 6 of the striker 4 of FIG. 1 shows that the striker 4 is detachable and replaceably attached to the striker support 3. This importance is described in detail in the general description section of the specification. The striker 4 can be replaced by loosening the set screw 6. The striker drive can be used all-round, ie in combination with the striker 4 of all kinds.

The shown embodiment of the striker drive unit shows a particularly high assembly degree, which allows for flexible attachment to other places or to other bodywork structures. Therefore, the striker support body 3 is arrange | positioned so that a movement is possible in the casing 7, the drive motor 1 is fixedly coupled with a casing, and the unit which consists of this casing 7 and a drive motor is a desired vehicle body location, or Fixing means (8) for fixing to the vehicle body structure portion is provided. The retaining clip 9 is confirmed well from FIGS. 1 and 2. The drive motor 1 is fixed to the casing 7 for the transmission 2 and the striker support 3 with this retaining clip. The fixing means 8 are four spring holes at the corners, through which the casing 7 can be fixed to the vehicle body structure portion, and further, the unit.

3 and 4 show a particular embodiment which moves advantageously without tilting. Instead of the sliding support of the striker support 3, in this example the striker support 3 is considered to be supported on the rotating roller 10 in the casing 7. Four rotating rollers 10 are shown. 3 and 4, the stopper cushion 11 for the striker support 3 is disposed in the casing 7. The stopper cushion 11 is elastomer plastic in this example, which reduces the impact sound when the door is closed. The stopper cushions 11 on the mutually opposing sides also prevent particularly loud noises when opening the door.

The illustrated embodiment is particularly advantageous and is excellent in the structure of the transmission 2 which increases the assembly degree of the drive unit. In this example the striker support 3 is advantageously considered to be driveable via an eccentric member 13 with a rotating roller 12. It is confirmed that the striker support body 3 has a receiving portion 14, and the eccentric member 13 engages from the transmission 2 into the receiving portion. This receptacle 14 is at the center of the striker support 3 constructed in the shape of a plate and is thus closed entirely. However, in this configuration, the receiving portion 14 may be opened on one side. It is important that the force transmission surface 15 is formed at the edge of the receiving portion 14, and the eccentric member 13 abuts on the force transmission surface 15 under the transmission force. The force transmission surface 15 is visible on the inner surface of the receiving portion 14 on the right side of FIG. 3. It is also confirmed that the eccentric member 13 in FIG. 4 is reached by turning the eccentric member 13 to the right from the exhibition fixed position (open position) of FIG. 3. The stroke is several mm, and in the illustrated embodiment it is about 6 mm. By the movement of the eccentric member 13, the striker supporter 3 is pressed against the right stopper cushion 11 in the casing 7. This is the gaze position. By the dead center position of the eccentric member 13 in FIG. 4, the force acting in the opening direction does not act on the eccentric member 13 via the lever arm, and is directly drawn into the axis.

The transmission 2 is configured as a worm transmission. The eccentric member 13 is on the worm wheel 17 of the worm transmission.

1 to 4 are characterized in that the striker support 3 comprises a spring force member 18 which loads the striker support in the open direction (preset position) with spring force. The spring member is present in other examples, but is not shown.

In the illustrated embodiment, the striker support 3 is not obstructed by the drive member, that is, in the illustrated embodiment, is not disturbed by the eccentric member 13 and the correct position (main visibility) from the open direction (preset position). Position) to be mechanically moved. In this regard, the importance is described in the general description of the specification. When the impact from left to right in FIG. 3 is applied to the striker 4, thus the striker support 3, the striker support 3 is not disturbed by the eccentric member 13 and is not difficult to spring the spring member 18. Reach to the gaze position (position shown in FIG. 4) against. In FIG. 4 a strongly compressed spring member 18 is shown. In FIG. 3, the receiving portion 14 of the striker support 3 is widened on the left side so that the eccentric member 14 does not reach the edge of the opposite position of the receiving portion 14. The free space for the eccentric member 13 is such that the eccentric member rotates by 90 ° between the open position and the correct position, but the dimension in the receiving portion 14 is slightly larger than the outer diameter of the movement path of the striker support 3. Is realized. As a result, the eccentric member can perform a full circular motion in the receiving portion 14, and can rotate 270 ° in the co-rotation direction from the locked position in FIG. 4 to the open position in FIG. This allows the use of a drive motor 1 that does not reversibly operate, which in some cases gives an advantage.

The corrective process and the open process are described with respect to the embodiment of FIGS.

In the locking of the automobile door, the door is closed, the latch abuts on the striker 4, and is latched in the main latch position (Hauptrast) by the latch. The impact from the closing of the door causes the striker 4 together with the striker support 3 to stopper cushion 11 from the position shown in FIG. 3 to the position shown in FIG. 4 against the spring force of the spring member 18. Move to the contact. Therefore, the collision noise of the horn is suppressed.

For example, the switching pulse is triggered by the latch reaching the main stop position (Hauptrast stellung), and the drive motor 1 is connected. Due to this, the door returned from the stopper cushion 11 first under the cooperation of the spring member is moved like the eccentric member 13 from the exhibition position in FIG. 3 to the gaze position in FIG. Move to the watched position. The drive motor 1 is cut off. The door of the car is corrected.

According to a function provided by the vehicle, the door grip is pulled or a control pulse is triggered to open the vehicle door. In both cases, the drive motor 1 is controlled, and as a result, the eccentric member 13 is returned from the watched position in FIG. 4 to the display corrected position in FIG. 3, and at the same time or staggered in time. The ratchet opens the latch from the main latching position. When the door is opened the striker support 3 again takes the action position of FIG. 3 together with the striker 4.

Control of the electric drive motor 1 can be carried out via a switch or a block circuit, it is possible to adjust the right turn and left turn of the electric drive motor (1). The spatial position of the striker drive unit according to the present invention is arbitrary, and longitudinal, lateral or hanging arrangements are possible.

When the eccentric member 13 is in the open position (front position), the striker support 3 can be moved to the correct position (main position) even when the drive motor 1 has failed. The above description illustrates this.

5 and 6 together make it clear that the movement to the locking position (main locking position) can also be effected mechanically by the manual adjustment device 20. The importance of this manual control device 20 for emergencies has been described in the general description, and so is pointed out.

5 shows the manual adjustment device 20 in the free position. In this example, the striker support 3 is driven by a motor only. On the other hand, in FIG. 6 of the side view corresponding to FIG. 5, the manual adjustment apparatus 20 is moved to fix a function position. Here, the striker support body 3 is fixed at the locking position (main locking position). Thereby the striker 4 acts as a floating striker, and the motor sighting aid loses its function.

FIG. 5 shows a transfer arm 23 having a casing 7, ie a manual adjustment lever 22 supported on a support plate 21, and a support roller 24 fixed thereto. The structure of the manual adjustment apparatus 20 provided with the force transmission surface 25 of 3), and the adjustment slider 26 of the vehicle body panel upper surface used for operation is shown by comparison with FIG.

If the motor drive unit does not function for some reason, the vehicle door is opened, and the adjustment slider 26 is moved to the fixing in Fig. 6, whereby the striker support 3 is moved to the correct position (main visibility). Position), where it is fixed. The dead center pass-through structure (Uebertotpunk-Konstruktion) of the manual adjustment device 20 ensures that the striker support 3 cannot be released by vibration.

The advantage of the structure according to the invention lies in the reliable door visibility even in an emergency. The difficult point in an emergency is to close the door of the car more strongly. This is because the opposite pressure of the seal rubber and in some cases the opposite pressure of the opening spring must be overcome, which otherwise the motor sighting aid handles in normal operation.

Fig. 7 is another modification, which corresponds to the embodiment inside. In this example the casing 7 has an additional receiving pocket 19, which is fixed to the receiving pocket via the fastening means 8. The receiving pocket 19 itself is then fixed to the vehicle body structure 16 by welding or other fixing method.

8 is an exploded view of another embodiment of the striker drive unit according to the present invention. Relational granting based on the above configuration is facilitated by the use of the codes already used above. The description is omitted.

In the embodiment shown in FIG. 8, as in the case of the embodiment shown in FIGS. 5 and 6, the receiving portion 14 in the striker support 3 has the eccentric member 13 in the moving direction of the striker support 3. It has dimensions within equivalent to the outer diameter of the track. This allows the eccentric member 13 to perform a 180 ° movement between the open position and the correct position, ie both positions are at their dead points. Both dead centers are shown in FIGS. 5 and 6.

The embodiment shown in FIG. 8 shows a striker support 3 supported on a rotating roller 10 in a casing 7, furthermore the rotating roller 10 is a spring-shaped guide on the upper and lower sides of the striker support 3. Arranged in the casing 7 on both sides of the 30, the guide is thus accommodated between the rotary rollers 10. This support of the striker support 3 is adjustable. That is, the support member 1 is installed at least on one side of the striker support 3 for adjustment in each support, and the support member itself is adjustable in a direction perpendicular to the moving direction of the striker support 3. The support member 31 is confirmed on the right side of FIG. In this case, two rotary rollers 10 are each accommodated in the support shell 32 (FIG. 9). The adjustable mobility of the support member 31 is in the embodiment shown two insertion bolts screwed into the casing 7. The support member 31 is shown in FIG. 9 as being configured as a wedge guide at the rear in the illustrated embodiment, and cooperates with the corresponding wedge surface of the casing 7. The support member 31 is moved in the direction of movement of the striker support 3 itself by the rotation of the insertion bolt 33 shown in FIG. 9, thereby simultaneously moving the striker support 3 by the wedge action of the wedge guide. It is moved vertically with respect to the direction and is thus in contact with the guide 30. As a result, the play at this location can be eliminated for the purpose. The door lock mechanism of the vehicle is sufficiently silent.

Finally, by means of the proper shape of the fixing point, the striker drive unit is provided with fixing means 8 for fixing it as a whole to the desired body structure 16, but slightly adjustable relative to the body structure in the fixed state, It is achievable that it can be fixed at each adjustment shift position. This can be done using an appropriately sized through hole or basket corner in the transmission casing. Basically, this technique corresponds to the adjustable mobility of the striker for the adjustment of the door lock, which is otherwise fixed in the floating body structure.
