Description

The invention relates to an electromechanical switch, in particular for actuating an electric parking brake in a motor vehicle, comprising a housing, a movably held on this control element, which can be transferred from a non-actuated position in at least one actuation position, at least one operatively connected to the operating element actuating element and at least an arranged in the housing electrical switching element.

Such an electromechanical switch, which is used for actuating an electric parking brake in a motor vehicle, is a safety-relevant component that must be able to withstand a very high number of actuations (typically 50,000 to 100,000) without damage. This far exceeds the number of actual operations of the switch during the average life of the motor vehicle. For this reason, the individual components of the switch are sufficiently large and robust designed to also perform the minimum number of required operations can. Conventional electromechanical switches therefore have a not inconsiderable size. This is especially true when components are provided to make a user the switching operation of the at least one switching element on the control haptic detectable, d. H. provide haptic feedback to the user on the control. The integration of such haptic components leads to a relatively complicated construction of the switch.

Electromechanical switches with switching elements and haptic components are for example in the DE 10 2005 053 931 A1 and in the US 5,957,273 described.

The DE 10 2013 108 756 A1 describes an electromechanical switch, in particular for an electric parking brake of a motor vehicle, in which a simple construction and a robust construction can be achieved in that the operating element is designed as a rocker switch and provided with a pivot arm, which can be pivoted against a magnetic return device. In the space between the magnetic return means and the rocker switching elements are arranged, whereby a compact design is achieved, which is favored by a relatively large lever of the return device on the switching arm. As a result of the magnetic return means, the switch is also relatively quiet, which is particularly desirable in higher-value vehicles, in which electronic parking brakes are used.

The WO 2012/010226 A1 describes a switch for an electric parking brake, which can be acted upon by a control element on a rocker switch, which is pivotable about two spaced apart axes for actuating two microswitches.

Object of the present invention is to provide an electromechanical switch, in which a reliable function can be achieved by a structurally simple structure.

This object is achieved by an electromechanical switch according to the invention, which is provided in particular for actuating an electric parking brake in a motor vehicle, comprising a housing, a movably held on this control element which can be transferred from a non-actuation position in at least one actuation position, at least one with the control operatively connected actuating element and at least one arranged in the housing electrical switching element, wherein the at least one actuating element is moved by moving the operating element in the at least one actuation position in the housing for transferring the at least one switching element from a first switching state to a second switching state and to cooperate with at least a Haptikelement to make a user the switching process haptically detectable, wherein the at least one haptic element in the housing spatially separated from at least a switching element is arranged.

In the switch according to the invention, a simple construction can be achieved in that the at least one accommodated and displaceable in the housing actuator is provided. When you press the control, the actuator is moved. This makes it possible to convert the cooperating with the actuating element switching element from a first to a second switching state. The at least one actuating element also cooperates with the at least one haptic element which is activated by the displacement of the actuating element in order to provide a haptic feedback to a user on the operating element. Separate components of the switch for interacting with the at least one switching element on the one hand and the at least one haptic element on the other hand can be saved by providing the actuating element, which allows both functions. In addition to the simple structure, a reliable function of the switch can be ensured because the number of moving components can be kept as low as possible.

It proves to be favorable when the at least one actuating element comprises a between the at least one switching element and the at least one haptic arranged and cooperating with these operating portion which is displaced upon actuation of the operating element from at least one switching element in the direction of the at least one haptic. This allows a compact and simple construction of the switch. The actuating portion is displaced away from the switching element, whereby this is transferred from the first to the second switching state. At the same time, the actuating portion is displaced in the direction of the at least one haptic and can cooperate with this. A haptic feedback is detected by the operating section and can be transmitted via the actuating element to the operating element. In the present embodiment, the at least one switching element, the actuating portion and the at least one haptic element can be positioned in particular below one another and arranged below the operating element. The switch can thereby have a slim, space-saving design.

The at least one switching element is preferably arranged between an actuating portion of the at least one actuating element contacting it and the operating element. In particular, the at least one switching element is positioned below the operating element and above the operating portion.

Position and orientation information such as "below", "above" or the like are presently considered as an installation of the switch such that the user faces the operating element (top side), "bottom side" designates a side facing away from the user of the switch.

It proves to be advantageous, in particular in combination with the two last-mentioned advantageous embodiments of the switch, when the first switching state is an activated state of the switching element and the second state is a deactivated state of the switching element. For example, the at least one actuating element holds the at least one switching element when the control element is not actuated, when it assumes the non-actuated position, in the activated state. The switching element can be permanently activated. When operating the operating element, the actuating element and in particular its actuating portion is displaced away from the switching element, and the switching element can assume the deactivated state. At the same time, the operating portion can be moved in the direction of the haptic. An electrical switching arrangement of the switch can interpret the activated state of the switching element as a non-actuated state of the switch and the deactivated state of the switching element as the operating state of the switch.

It proves to be advantageous if the switch comprises a printed circuit board accommodated in the housing, on which the at least one switching element is fixed. The circuit board may be provided, for example, for supporting a plurality of switching elements of the switch. Furthermore, the circuit board electrical light elements for illuminating the switch, in particular the control element record. Electrical contact members for contacting the switch in the installed state can be provided.

At least one light-emitting element is preferably arranged on a side facing the operating element. By resulting in this way proximity to the control element light guide elements for coupling the light can be simplified or even saved.

A sealing element, for example a sealing mat, can be arranged between the printed circuit board and the operating element in order to protect the printed circuit board from the ingress of moisture. The sealing element may be at least partially optically transparent to light of the luminous element.

It is advantageous if the at least one actuating element is displaceably guided on the housing. By guiding and in particular displaceable storage tilting of the at least one actuating element is avoided and ensures reliable operation of the switch. For example, the at least one actuating element is guided on the inside on at least one housing wall.

It may be provided that a guide groove for the at least one actuating element is provided in a housing wall, for example a housing side wall, and that the at least one switching element and / or a circuit board holding this the switch housing wall and engaging in the guide groove at least one actuator housing inside covered. For example, the at least one actuating element engages with a bearing section in the guide groove. The circuit board or the at least one switching element covers the actuating element and in particular the bearing portion at least partially, so that this or this secured in the guide groove and the switch is thereby formed even more reliable. In order not to interfere with the movement of the actuator, some play may be provided between the circuit board or the switching element and the actuator.

In an advantageous implementation of the switch, it proves to be advantageous if the at least one actuating element comprises a cooperating with the at least one switching element and the at least one haptic actuating portion and two spaced-apart and interconnected via the operating portion leg, which are guided displaceably on the housing. The actuating element can thereby in particular have a U-shaped form. The legs can each form a bearing portion, which is displaceably guided on the housing, in particular in a guide groove of the housing. The legs are preferably guided by opposite housing side walls of the housing. By providing the two legs guided on the housing, tilting and / or tilting of the actuating element can be avoided.

Conveniently, the at least one switching element is positioned between the legs. The switching element can be encompassed in this way by the legs and the operating portion of three sides. The legs can extend laterally past the switching element along a housing wall and be acted upon by the operating element with an actuating force.

It can advantageously be provided that a circuit board holding the at least one switching element is at least partially positioned between the legs. The legs can also be guided laterally past the circuit board along housing walls.

The operating element preferably comprises contact members which contact a respective leg on a side facing away from the actuating portion and transmit a movement of the operating element to the legs. The tongue-like contact members, for example, can rest permanently or temporarily against a respective limb when the operating element is transferred from the non-actuation position into the at least one actuation position. On the legs an actuating force acts to move the at least one actuating element. The rotational movement of the operating element can be converted into a particular straight-line displacement movement of the actuating element.

In an advantageous implementation of the switch, in particular for an electric parking brake, the operating element is a rocker pivotable about a pivot axis or comprises such a rocker. The rocker may comprise at least one contact member for contacting the at least one actuating element. The contact member is pivoted upon actuation of the rocker and is at least temporarily and preferably permanently on the actuating element, for example, at least one leg of the same to move the actuating element.

The operating element can be transferred by contact with the actuating element again from the operating position to the non-actuating position.

It is particularly favorable if the at least one haptic element comprises or forms the at least one restoring element. Separate reset elements can be omitted. Not only a haptic feedback to the user can be done via the haptic, but the actuator can be moved back to the starting position after the operation of the switch.

It proves to be favorable, in particular in combination with the last-mentioned advantageous embodiment of the switch, if the at least one haptic element is designed to be elastically deformable and in particular reversibly deformable. When deforming the haptic, a user is provided with a haptic perception about the switching process. By a reversible recovery deformation, the actuator can be moved back to the starting position as mentioned above.

It is advantageous if the at least one haptic element is or comprises a haptic dome which is compressed by the at least one actuating element when actuated, preferably that the haptic dome can be erected when the operation is omitted and acts as a restoring element for the at least one actuating element. At the Compression of the haptic dome, for example by the operating portion, its height or volume can be reduced. About the force required for this purpose, the user learns a haptic feedback on the control. The haptic dome, for example, bell-shaped or at least partially frusto-conical shape. Preferably, a wall of Haptikdoms is formed such that a defined pressure point can be achieved by the Haptikdom can collapse at a defined operating force. Such a haptic dome is, for example, a snap-action element, which preferably snaps back into the initial state when the actuating force is lost due to reshaping and acts as a return element for the at least one actuating element.

The at least one actuating element may preferably be associated with two or more haptic elements, which are preferably configured identically.

The switch preferably includes a haptic mat that includes or forms the two or more haptics. The two or more haptic elements are preferably formed integrally with the haptic mat. This greatly facilitates the manufacture and assembly of the switch. For example, the haptic mat is inserted during assembly in the housing interior, so that a plurality of haptic elements can be mounted in a simple manner.

In an advantageous implementation of the switch, it is advantageous if the switch comprises two switching elements, two actuators and at least two Haptikelemente and if the control element from the non-actuated position in two operating positions can be converted, in which a respective actuating element is moved to transfer the respective switching element of a first switching state in a second switching state and for cooperation with the respective haptic. Depending on the operating position in which the operating element is transferred, the first switching element or the second switching element is effective by the first actuating element or the second actuating element is displaced. Starting from the non-actuation position, the operating element for transferring into the corresponding actuating position, for example, to move in two opposite directions and in particular to pivot.

For a compact design of the switch, it is advantageous if the switching elements and / or the actuating elements are each positioned laterally side by side in the housing.

The desk 10 includes an electrical circuit arrangement 72 holding a circuit board 74 includes. In addition, the switching arrangement comprises 72 two electrical switching elements 76 on the circuit board 74 are fixed and are contacted via this electrically.

The circuit board 74 is in the housing interior 28 taken and for example parallel to one of the housing bottom 36 aligned level. The circuit board 74 in the present case extends over the second space area 32 to the first room area 30 , In the first room area 30 can, for example, on the circuit board 74 fixed contact members may be arranged (not shown), via which an electrical contact of the switch 10 with a wiring harness or the like is possible. For holding the circuit board 74 shows the case 12 Retaining projections, of which exemplified in 3 retaining projections 78 inside the housing side walls 18 . 20 are shown. At the switch 10 is the circuit board 74 on the retaining projections 78 and any other retaining projections, but it could also by force and / or positive connection, such as a press fit in the housing 12 be held.

At the rocker 56 facing side of the circuit board 74 is at least one electric light element 80 arranged with the the seesaw 56 can be backlit. Due to the small distance of the luminous element 80 from the ceiling wall 62 can be made a favorable Lichtauskopplung, advantageously without light-guiding elements.

The present case identically designed switching elements 76 are at the seesaw 56 opposite side on the circuit board 74 fixed, ie in this case down toward the housing bottom 36 , Inadvertently penetrates a liquid into the housing 12 a, are the switching elements 76 thus better protected against damage or malfunction.

The switching elements 76 are side by side in the second room area 32 arranged and with respect to each other in the transverse direction of the switch 10 aligned rotated by 180 °. A respective switching element 76 includes a switching element 82 that goes down towards the case back 36 projects. 2 shows for one of the switching elements 76 dashes the contour of the switching element arranged thereon 82 , The switching elements 76 are parallel to the pivot axis 50 (in the transverse direction of the housing 12 ) are dimensioned so that respective gaps to the housing side walls 18 . 20 available.

Laterally next to the switching elements 76 are on the housing side walls 18 . 20 respective adjacent guide grooves 84 formed, each switching element 76 on each side wall of the housing 18 . 20 a guide groove 84 assigned. Overall, therefore, four guide grooves 84 available. Between guide grooves 84 a housing side wall 18 . 20 is a respective rib 86 arranged, for example, a retaining projection 78 having.

For actuating the switching elements 76 includes the switch 10 two actuators 88 where each actuator 88 a switching element 76 assigned. The actuators 88 are identically designed and side by side in the second space area 32 arranged.

Each actuator 88 is substantially U-shaped with two spaced apart legs 90 and an operating portion connecting them 92 acting as a bridge between the thighs 90 serves. Starting from the operating section 92 have the thighs 90 in the direction of the seesaw 56 ,

The actuators 88 are sized so that the thighs 90 positively between the housing side walls 18 . 20 are arranged. A respective leg 90 engages in a guide groove 84 one. The actuator 88 This is due to the housing 12 slidably guided and stored, so that the actuating element 88 on the housing 12 down towards the case back 36 or in the opposite direction upwards in the direction of the rocker 56 can be moved.

A respective switching element 76 is between the thighs 90 of the associated actuating element 88 positioned. Also the circuit board 74 is in sections between the respective thighs 90 the actuators 88 positioned. The thigh 90 are laterally on the switching elements 76 and the circuit board 74 passed and can the contact members 70 the seesaw 56 to contact. In a non-actuated position of the rocker 56 lie the contact members 70 on the thighs 90 both actuators 88 at ( 2 ).

stop members 94 , here configured as shoulders on the thighs 90 , limit the displacement of the actuators 88 towards the seesaw 56 , The stop members 94 are on the thighs 90 at her the circuit board 74 arranged facing side and can limit the movement of the actuators 88 interact with this.

The operating sections 92 further comprise projections in the direction of the housing bottom 36 wherein each actuation section 92 two projections 96 having.

The desk 10 has a haptic arrangement 98 on. The haptic arrangement 98 comprises a haptic mat made of an elastically deformable and in particular reversibly moldable material, for example a silicone material.

The haptic mat 100 includes several identically designed haptic elements 102 , each in the form of a haptic dome 104 , From a base of the haptic mat 100 stand the haptic domes 104 in the direction of the circuit board 74 from. Every haptic dome 104 includes a lower, frusto-conical region and an upper (circular) cylindrical area. Each actuator 88 , in particular its operating section 92 , are two haptic domes 104 associated with each haptic dome 104 with a lead 96 interacts.

The haptic dome 104 are such that they are elastic under pressure and in particular reversibly deformable. In this case, a respective pressure point is defined such that the haptic dome 104 is compressed with a snap action when the operating section 92 is moved. Conversely, the haptic dome 104 upright on recovery and a restoring force on the operating section 92 exercise. The haptic dome 104 set in this way a respective return element for the actuators 88 ready.

From what has been said that the operating section 92 between the haptic domes arranged below 104 and the above arranged switching element 76 is positioned. The haptic dome 104 are spatially separated from the switching elements 76 in the case 12 arranged.

Below is the function of the switch 10 received.

When the seesaw 56 is not subjected to a tensile or compressive force by a user, it assumes a non-actuated position. Without actuation force of the user act on the haptic dome 104 the actuators 88 with one on the seesaw 56 directed force. The actuators 88 lie over the stop members 94 on the circuit board 74 at. The thigh 90 are sized to fit the contact members 70 issue.

For a switching operation, the rocker 56 be converted into two operating positions, characterized in that the rocker 56 by a downward pressure force or by a pulling force upward about the pivot axis 50 is pivoted. This is not shown in the drawing. When pivoting is a pair of contact members 70 on the respective thighs 90 an actuating element 88 at. The rotary motion of the rocker 56 is in a shift of the corresponding actuator 88 transformed. The actuator 88 will be in the case 12 moved down and is doing in the Führungsnuten 84 guided. The other actuator 88 remains in his position.

The operating section 92 gets away from the switching element 82 towards the actuator 88 associated Haptikdome 104 postponed. The switching element 76 is thereby transferred from a first switching state to a second switching state. The haptic dome 104 be from the operating section 92 about its projections 96 reversibly deformable compressed. The resulting snapping movement of the haptic dome 104 provides a user with haptic feedback about the switching process.

Does not the actuating force on the rocker 56 , the haptic domes can 104 erect as mentioned and act as return elements for the actuators 88 , The haptic dome 104 snap back into their initial configuration, causing the actuators 88 towards the seesaw 56 be moved. The operating section 92 contacts the switching element 82 , and the switching element 76 is transferred from the second switching state back to the first switching state. About the thighs 90 becomes the seesaw 56 pivoted back into the non-actuated position.

In the non-actuated position, the operating sections act 92 with the switching elements 82 together, wherein the respective switching element 76 assumes a permanently activated state. In the operation operation, when the operation section 92 from the switching element 82 is moved away, takes the respective switching element 76 a deactivated state. The interconnection of the circuit board 74 is such that the activated state of the switching element 76 as non-actuated state of the switch 10 is considered and the non-activated state of the switching element 76 as the operating state of the switch 10 ,

The desk 10 is characterized by a structurally simple design at the same time compact design. The actuators 88 serve two functions. First, they can be used to the switching elements 76 to transfer from the first to the second switching state and vice versa. On the other hand, the actuators act 88 on the haptic order 98 to haptic feedback on the rocker during the switching process 56 provide. By the displacement of the actuators 88 , in particular their operating sections 92 between the haptic domes 104 and the switching elements 76 is a small adjustment and thus a low height for the switch 10 achieved. Electrically contacted safety mats, such as provided with conductive contacts Haptikdome 104 as in the prior art, can be omitted. The use of separate switching elements 76 therefore also allows reliable operation of the switch 10 ,

The desk 10 is also designed for easy installation. For this purpose, for example, the circuit board 74 , then the actuators 88 and finally the haptic mat 100 over the first housing opening 34 in the housing part 14 be used. The second housing part 16 can with the first housing part 14 to close the case 12 be locked. Due to the planar contact surface 44 is the correct fit of the haptic mat 100 in a closed housing 12 ensured. At the beginning of the assembly or at its completion, the rocker can 56 with the housing part 14 be locked.

Between the circuit board 74 and the seesaw 56 For example, a sealing element, for example a sealing mat, can be arranged. For example, the sealing mat is on the circuit board 74 on. The sealing element protects the circuit board 74 from penetrating moisture, eg. B. due to capillary action. Preferably, the sealing element for coupling the light of the luminous element 80 at least partially transparent.
