Description

Auxiliary actuator, housing and rotary locking device

for a motor vehicle

The present invention relates to an auxiliary operating device according to the preamble of claim 1. Furthermore, the invention relates to a housing according to the preamble of claim 1 1 and a rotational locking device according to the preamble of claim 16.

Twist locking arrangements are widely used in motor vehicles, e.g. as a steering wheel lock, door lock, fuel tank lock, etc. Other applications are currently available in electrically powered vehicles, e.g. in electric cars or those with hybrid drive. Locking devices or closure devices of the present type are used in such motor vehicles in particular for locking the necessary batteries for the drive batteries or accumulators in the vehicle and thus ensure their tight fit. In such a lock, which usually with a rotation of a bolt by 90 ° relative to associated with a housing, it is desirable to receive feedback about a lock being made to ensure that a battery is properly held and locked and thus operational. This is ensured by a switch operated in the course of locking.

The rotary locking devices of the prior art are disadvantageous in that the display of a lock or the output of a corresponding signal is not regularly reliable, since the bolt of the rotary locking device, which dips into a housing to be locked with this, sometimes inaccurately immersed, namely in the direction of all three axes (X, Y, Z). Upon rotation of the bolt for the purpose of locking relative to the housing, as a result of which the switch is to be actuated, it may happen that the switch is not triggered because the bolt is, for example, twisted or immersed in a Z-direction (vertical) is. In some cases, it may happen that the bolt locked by 90 ° as prescribed, but due to the twisting and moving in the Z direction, not the switch actuated. So an error would be detected that does not exist or vice versa. In order to minimize such problems, it is known in the art to provide a housing having a movable X- and Y-directional plate, which tolerances in the X and Y direction (eg horizontally) compensate

can. On the plate there is a switch, which should detect the complete latching. However, this arrangement has drawbacks in that the items are complex and expensive. Further, the switch is mounted on the movable plate, so that the associated wire harness must also be arranged to be movable or trackable, e.g. as described in DE 10 2006 0172 48 B4. The lock housing is therefore complicated only with high handling costs costly seal.

Proceeding from this, the present invention has the object to overcome the above-described problems and to provide an arrangement for rotational locking available, in which a lock despite the large tolerances or inaccuracies occurring is reliably detected.

This object is achieved with respect to the additional actuating device by the features of claim 1, with respect to the housing by claim 1 1, as well as with respect to the rotary locking device by claim 1 6.

In this case, the device is able to filter out only the rotation about the Z axis from the four degrees of freedom (linear movement in X, Y, Z axes and rotation about the Z axis) and to detect their exact angular position. The movements in three other axes are selected and ignored.

An auxiliary actuating device is proposed for a rotary locking device in a motor vehicle, which has a base element with a receiving device arranged thereon, wherein the receiving device is formed with a receptacle for abutment against opposite regions of a male corresponding bolt element. For engagement with the bolt element, the receptacle has at least one pressure element. Furthermore, the additional actuating device comprises at least one contact surface for rotatably supporting the auxiliary operating device in a guide and an actuating element. ment for actuating a corresponding or cooperating actuator in a lock.

In one embodiment according to the invention, the pressure element has at least one prestressed element, in particular a spring-elastic element or a slide element.

In a further embodiment of the invention, the receiving device is formed integrally with the base member.

According to yet another embodiment of the invention, the abutment surface is formed on the base element, in particular in an edge region of the base element. The contact surface may be formed as a sliding surface.

The auxiliary operating device has in one embodiment an actuating element, which is designed to actuate a switch. The actuating element is arranged, for example, on an edge region of the additional actuating device and / or on an edge region of the basic element. It can be designed as a nose and / or as a projection. The actuator protrudes in an embodiment in the outer circumferential direction of the auxiliary operating device, in particular of the base element, forth.

In one embodiment of the invention, the receptacle has a substantially V- or U-shaped cross-section.

Also proposed is a housing for a rotary locking device for a motor vehicle, comprising a housing bottom with a passage opening for a bolt element, and at least one wall element projecting from the housing base and at least partially around the passage opening. In this case, a guide is formed on the at least one wall element for rotatably guiding or supporting the at least one contact surface of an additional actuating device according to the invention. In one embodiment, the guide has a support surface for the at least one contact surface. The guide and / or the bearing surface may be formed on a side facing away from the housing bottom end side of the at least one wall element. The guide and / or the support surface are at least partially formed annular in one embodiment.

In yet another embodiment of the invention, the housing has a receptacle for the arrangement of an actuating device, which cooperates with the actuating element of the additional actuating device.

According to the invention, a rotary locking device for locking a battery in a motor vehicle, in particular a motor vehicle with electric drive, is proposed, wherein in the guide of a housing according to the invention an additional actuating device according to the invention is rotatably guided.

In one embodiment, the actuating element cooperates with the actuating device rotatably. The actuating element can be arranged such that upon locking of the rotary locking device, the actuating device is actuated by the actuating element. In this case, the actuating device can generate an electrical signal in one embodiment.

It is also proposed the use of the rotary locking device according to the invention for locking a battery assembly in a motor vehicle, in particular in an electrically powered motor vehicle.

In the following description and the drawings, the same reference numerals correspond to elements of the same or comparable function.

Fig. 1 shows an additional actuating device 1 according to the invention and a housing 2 according to the invention, in which the additional actuating device 1 can be received in a rotationally movable manner. The auxiliary actuating device 1 and the housing 2 are used, for example, to form a rotary locking arrangement or rotary locking device 3 according to the invention. The auxiliary operating device 1 is used to provide a signal in the event of a successful locking. to provide casual and thus represents an additional device for actuating eg a switch.

The additional device for actuation or additional actuating device 1 consists in the embodiment of Fig. 1 of a plate-like base member 4 with partially open bottom 5. In the opening of the bottom 5 is at least one pressure element 6, e.g. a spring element 7 in e.g. Formed a W-shaped bent spring, such that the outer legs 7a, 7b of the W-shaped bent spring element 7 are supported on an edge of the open bottom 5 of the base member 4. The spring element 7 is in this case pretensioned with respect to the opened bottom 5, e.g. by clamping on this. In order to prevent the legs 7a, 7b from slipping relative to the base element 4, these may be e.g. be suitably trapped, e.g. be by clamping, also integrally formed or otherwise secured by form, force or cohesive types of connection.

An inner region or middle region of the W-shaped bent spring element 7 or of the pressure element 6 is designed in the form of a receptacle 8 for a bolt element 9, such that the pressure element 6 is engaged or abutted on two opposite regions of the bolt element 9 can, so that a clamping of the bolt member 9 is possible. The receptacle 8 has, for example, a V-shaped or U-shaped cross section through which ramp surfaces 8a, 8b are provided for guiding a penetrating or submerging pin element 9. The spring element 7 that is supported on the open bottom (edge) forms a receiving device 10 for a corresponding bolt element 9, into which such a head, eg with a correspondingly formed head 11, can at least partially submerge. In order to be able to catch the immersed bolt element 9 in the best possible way, the receptacle 8 preferably has a cross-section adapted to the bolt element 9 to be caught or accommodated. Dips the bolt member 9 at an angle or with rotation in the receptacle 8, the pressure element can exert a compressive force against the bolt member 9 due to its bias, for example against diametrically opposite ends or along a length thereof. If the bolt element 9 does not dive as intended or not with the desired length, rotation of the same may occur nevertheless cause a rotation of the receptacle 8 and thus the associated additional actuating device 1.

The auxiliary operating device 1 has a e.g. Edge area 12, e.g. an edge region 12 in the form of a plate edge, within which a bearing or support surface 13 is formed. The abutment surface 13 is e.g. formed on the base 4, e.g. in an edge region 12 of the base element 4. The contact surface 13 is z. B. on a bottom 5 facing side of the edge region 12 is formed. The contact surface 13 serves to support or abut against a housing 2 according to the invention, in particular on a contact surface formed thereon. The abutment surface 13 preferably has a closed ring shape, but may also be segmented, e.g. be formed with wing elements or otherwise. The contact surface 13 is adapted to the rotational mobility on a support surface, in particular in an at least partially annular guide, e.g. a corresponding circular guide of a housing 2 according to the invention, to ensure. The abutment surface 13 is e.g. designed as a sliding surface, in order to have the least possible resistance in a rotational movement of the auxiliary operating device, e.g. by coating with Teflon, in the form of a polished or smooth surface, etc. Within a circumference of the contact surface 13, for example, the receiving device 10 is arranged, which for example extends beyond a lower end 14 of the contact surface 13 and the base member 4 addition.

The additional actuating device 1 has an actuating element 15, for example in the form of a nose protruding in the outer circumferential direction (eg, X, Y direction) from, for example, the base element 4 or, for example, a projection 1 6. The actuating element 15 is connected to a (outer ) Edge region or a peripheral edge of the base member 4 is arranged. It is also conceivable, for example, to arrange the actuating element 15 on the receiving device 10. The actuating element 15 cooperates with a corresponding actuating device of a housing 2 according to the invention. The actuating device of the housing 2 is, for example, a switch and, for example, emits an electrical signal to an evaluation unit when an actuation has taken place by the actuating element 15 as a result of a rotational movement of the additional actuating device 1 as a result of a Verriegeins. The actuating element 15 is suitable, for example, for exerting pressure on a switching element of the actuating device as a result of locking and thus triggering a switching operation (FIG. 5). The actuating element 15 may be formed integrally with the additional actuating device 1, for example the base element 4, or otherwise attached thereto, eg glued, screwed, etc.

FIG. 2 shows a further embodiment of an additional actuating device 1 according to the invention, in which the base element 4 is substantially disk-shaped. The receiving device 10 in this case has two spring elements 7c, 7d formed integrally with the base element 4 as pressure elements 6, each of which is e.g. V-shaped and cooperate upon receiving a pin member 9, in particular biased against a male pin member 9 are arranged on the base member 4. The inwardly opposed legs of the spring elements 7c, 7d are at a distance a from each other, whose width is e.g. is adapted to a male pin member 9, in particular to a desired for the desired locking head 1 1 of a bolt member 9 and corresponds to this. The two spring elements 7c, 7d form, as well as the W-shape of the previously described embodiment, a tapered in cross-section receptacle 8 of the receiving device 10, which also favors a dipping of a bolt member 9 by ramp surfaces 8a, 8b or guide supports.

In one embodiment, not shown, the base member 4 comprises, for example, a slider element which on both sides of a receptacle 8 (in the form of a recess, an opening, etc.) for the male pin member 9 is displaceable, e.g. having spring-loaded jaws or elements, so that an interposed bolt element 9 can be pressurized. The slider element may e.g. include a slide, which is designed as a backdrop.

The auxiliary actuating device 1 interacts with a housing 2 according to the invention, with which a bolt element 9 is intended to lock when rotated relative to one another. The housing 2 has a housing bottom 17, within whose one example, passage opening 18 for a bolt element 9, in particular for a head 1 1 of a bolt member 9, is formed. A bolt element 9, together with the housing bottom 17, can rotate in rotation with, for example, removal of the bolt element 9 from the passage opening 18, by projecting a head piece 11 of the bolt element 9, which projects laterally, ie transversely to the passage direction D, through a handle element 19 of the bolt element 9 (ie, eg T-shape or upside-down L-shape), passed through the passage opening 18 and the bolt member 9 is rotated after passage of the head piece 1 1 relative to the housing bottom 17. In this case, the passage opening 18, for example, a slot, the head piece 1 1, for example, of substantially rectangular cross-section. If the rectangular cross section is rotated after passing through the corresponding slot around an axis A, the bolt member 9 can not be retracted without re-rotation, so there is a lock. The dimensions of the head must be suitable in so far as to surmount after rotation of the head at least one edge of the passage opening 18, ie a width of the passage opening 18. Preferably, the head piece 1 1 bevelled areas or areas, eg ramp surfaces 1 1 a, the one Assist immersion in the recording 8. An in the direction of passage D front part of the head 1 1 has in this respect the shape of a roof, for example a saddle roof or a hipped roof.

The housing 2 has a wall element 20 which is arranged around the passage opening or the recess 18, e.g. essentially circular. The wall element 20 protrudes from the housing bottom 17, for example in the direction of passage D of the bolt element 9, from the housing bottom 17 and is, for example, annular, for example hollow-cylindrical or in the manner of a pipe section. The wall element 20 may be multi-piece, e.g. in the form of several column elements, or be formed in one piece or, for example, have different cross-sections, for example, from the housing bottom 17 in the direction of passage D tapered cross-sections.

The wall element 20 has a guide 21, for example, with a distance b from the housing bottom 17, on which an additional actuating device 1 according to the invention can be supported or guided in a rotationally movable manner. Between additional operating Device 1 and housing bottom 17 is formed by the wall element 20 insofar as a cavity in which a locking bolt element 9 can be accommodated. The distance b is set, for example, by selecting a corresponding height of the wall element 20, in particular such that a bolt element 9 with the intended immersion depth can dip into the guided in the guide 21 auxiliary actuating device 1.

The guide 21 of the housing 2 is formed for example in the form of a groove 22, for example as an annular groove on an end face of the wall element 20 (in the direction of passage D), which is opposite the housing bottom 17. The groove 22, e.g. with the cross section of a semi-open rectangular groove, for example, forms a support surface 23 for vertical support (Z direction), and an edge 24 for horizontal support (X, Y direction) of a recorded in the guide 21 additional actuating device. 1 The bearing surface 23, like the abutment surface 21, may be formed as a sliding surface in order to have the least possible resistance in a rotational movement of the auxiliary actuating device, e.g. by coating with teflon, by a polished surface, etc.

In order to secure the auxiliary operating device 1 from falling out of the guide 21 and exert a counterpressure on a dipping bolt element 9, the housing 2 can be closed with a cover (not shown) or abutted against a closing element such as e.g. Mounting wall, a fastening device, etc. are urged. For this purpose, the housing 2 can, for example, have mounting flanges, with which it can be attached to such e.g. permanently releasably attached. The guide 21 can also be arranged within the longitudinal extent (Z-direction) of a wall element 20, that is, between the housing bottom 17 and end face, so that falling out is avoided by the guide 21, which is for example slot-shaped or rectangular.

The housing 2 has, for example, a recess or a receptacle 26 for an actuating device 27, which is formed, for example, in the wall element 20. The receptacle 26 is equipped, for example, with engagement elements 26a, which, for the purpose of mounting with engagement elements 27a of the male actuator, are tion device 27 correspond, for example by suitable fits. The actuator 27 may be mounted in the receptacle 26 in other ways, for example by press fit, gluing, screwing or known force, form or cohesive method. To receive the actuating device 27, the wall element 20 can be material-reinforced in the region of the receptacle in order, for example, to create a larger support surface and / or to form the engagement elements 26a.

The housing bottom 17 may have an edge region 28, which projects laterally beyond the dimensions of the wall element 20 in order to provide additional support surface for the objects to be locked with the bolt element 9, for example in an electrically driven motor vehicle to be locked accumulators or batteries of a battery pack , The housing bottom 17 may additionally have a fitting area 29, e.g. in the form of a cap, which is adapted to the shape of the object to be fixed in order to ensure a support in the vertical and horizontal directions (Fig. 6).

The housing 2 according to the invention and the additional actuating device 1 are, in particular together with the actuating device 27, arranged to form a locking arrangement according to the invention, in particular a rotary locking device 3 for a motor vehicle, or used in such. In particular, with the rotary locking device 3 according to the invention, e.g. Batteries locked in a motor vehicle, the batteries to the drive of the e.g. serve electrically powered vehicle. For example, a bolt element 9 is arranged on the batteries, which is intended to lock with a housing 2 according to the invention, wherein the housing 2 is fixedly connected, for example, to a body element of the motor vehicle. The body element can simultaneously form a housing cover for the housing 2.

To form the rotary locking device 3 according to the invention (FIG. 3), an actuating device 27 is arranged in the receptacle 26 and the additional actuating device 1 according to the invention in the housing 2 according to the invention, for example inserted into the guide 21 thereof. In this case, the contact surface 13 the additional actuating device 1 in the guide 21 of the housing 2 brought to rest or guided, for example by abutment on the curved or annular bearing surface 23. Thus, a rotational mobility of the auxiliary operating device 1 in the housing 2 is ensured.

When locking a bolt element 9 is guided with its head 1 1 in the direction of passage D through the housing bottom 17 of the housing 2 and rotated in a closing direction (arrow Fig. 5). When passing, the bolt element 9 according to the invention (with, for example, its head 11) plunges into the receptacle 8 of the receiving device 10 of the auxiliary operating device 1 accommodated in the housing 2, such that the at least one pressure element 6 of the receptacle 8 corresponding to the bolt element 9 is connected to e.g. the ramp surfaces 8a, 8b on the bolt member 9, in particular on the head 1 1 of the bolt member 9 comes to rest. The V-shape of the arrangement of the spring elements 7 and 7c, 7d of the pressure element 6 can support the guidance of the bolt member 9 during immersion.

Due to the immersion of the bolt member 9 in the receiving device 10, a compressive force is exerted by the pressure element 6 of the receptacle 8 on the bolt member 9, in particular by the bias of the respective pressure element 6. Between the bolt element and additional operating device, a quasi-rigid connection in e.g. Achieved a form of clamping. During a rotation for the purpose of locking, the bolt element 9 caught in the receiving device 10 now rotates the additional actuating device 1 in the guide 21. In contrast to the prior art, a switching operation is triggered by the auxiliary operating device 1, not by the toleranced bolt element. 9

The advantages according to the invention arise in particular when the bolt element 9 is inserted into the housing 2 with high inaccuracy. The tolerances can be several millimeters and include both deviations in X and Y direction (horizontal) and in Z direction (vertical). Due to the rotatable mounting of the auxiliary operating device 1 such tolerances are compensated. If the bolt element 9 dives into the receptacle 8 in such a way that the respective corresponding cross sections thereof are aligned with one another, the at least one pressure element 6 can rest along the bolt element 9. As soon as a rotation of the bolt element 9 takes place, the additional actuating device 1 thus rotates together with the bolt element 9 and reliably triggers the actuating device 27 by means of the actuating element 15 when the locking position is reached (for example after approximately 90 degrees).

If the bolt element does not penetrate far enough into the receptacle 8 (Z direction), a compressive force against the bolt element 9 will be exerted only if it bears against the at least one pressure element 6 in the form of the spring elements 7, 7c, 7d of the receptacle 8 a rotation is urged. Further rotation of the bolt element 9 then causes the receptacle 8 to rotate together with the bolt element 9, whereupon in turn a signal is reliably output as soon as the actuating element 15 actuates the actuating device 27. A deviation of the bolt member 9 from a target position in the Z direction is thus compensated and is irrelevant to the intended reliable operation of a switch.

If the bolt element 9 dips diagonally or twisted (X, Y direction) into the receptacle 8, it rotates together with the additional actuating device 1 first in its guide 21 until immersion to minimum resistance of the resilient spring elements of the at least one pressure element 6 meets, which now exert a pressing force on the bolt member 9, or clamp this. Again, a signal is reliably generated as soon as the auxiliary operating device 1 with its actuating element 15 has actuated the actuating device 27 on the housing 2 as a result of a rotation. Tolerances of the inaccurately introduced into the housing 2 bolt member 9 in the X and Y directions or inaccuracies are compensated.

If the pin with horizontal inaccuracy or offset to the receptacle 8 (in the X direction, for example) enters the receptacle 8, for example, the at least one pressure element 6 (in the form of, for example, the spring element 7 or 7c, 7d) correspondingly follows. A reliable signal generation is guaranteed in this case. The same applies to inaccuracy or offset, in the Y direction, wherein the pressurization of the bolt member 9 by the pressure element 6 allows a quasi-rotatable connection with a partially submerged or received bolt element 9.
