However, known push-button devices consist of various separate functional components. Disclosure of the invention

[0002] The invention relates to a push-button device for an electronic device, comprising an operating unit, comprising at least one actuating element with a touch surface for receiving an actuating movement of a user, at least one triggering element with a trigger surface for interacting with a, in particular tactile, switching mechanism of the electronic device, at least one reset element for deflecting at least the actuating element back after an actuating movement of the user, and at least one light guide element for transmitting a light signal from a light source of the electronic device to the touch surface of the actuating element.

[0003] It is proposed that the actuating element, the triggering element, the reset element, and the light guide element be formed by a single, one-piece, preferably monolithic, push-button component. This advantageously allows for cost-effective manufacturing, simplified assembly, and / or a reduction in the number of components. Potential sources of error can be advantageously eliminated, thus achieving high reliability and / or a long service life.

[0004] The push button device is, in particular, at least one functional component of a push button. Alternatively, the push button device can also constitute a push button in its entirety. A push button is, in particular, a button that can be actuated by manual pressing. Specifically, the push button is a switching element that serves to (temporarily) establish or break an electrical contact by manual pressing or actuation. Unlike a switch, which remains in a specific set position after being actuated, the push button preferably returns automatically to its initial position after being released. The push button can be a normally open (NO) push button, a normally closed (NC) push button, or a changeover (RS) push button.The electronic device differs in particular from a doorbell, a keyboard / computer keyboard, a light switch, a kitchen appliance, a vehicle, a personal computer, and / or a game console. Preferably, the electronic device is an internet gateway and / or radio module for remote control and / or remote monitoring of heating systems, preferably building heating systems. The control unit is in particular an assembly comprising the components of a push button required to receive an actuation movement and transmit it to a tactile switching mechanism of the electronic device. The tactile surface is in particular a surface of the actuation element of the control unit that is provided to the user for manual operation.Preferably, the touch surface is raised relative to its surroundings, in particular relative to a base element of the control unit and / or relative to a housing part surrounding the actuating element when mounted in the electronic device. The touch surface can be flat and smooth or have a surface roughness / pattern. The touch surface can have a label or print with one or more symbols, one or more colors, or the like.

[0005] The release element is preferably spatially separated from the actuating element. The release surface is preferably located inside the electronic device when installed. The tactile switching mechanism of the electronic device can, for example, be arranged on a printed circuit board or be electronically connected to a printed circuit board. The reset element is preferably spatially separated from the actuating element and / or the release element. The reset element is preferably located inside the electronic device when installed. The interior of the electronic device is preferably surrounded by a housing unit of the electronic device that includes the housing part. The light guide element is preferably spatially separated from the reset element and / or the release element.The light guide element is preferably arranged partially overlapping with the actuating element. The light guide element is preferably arranged partially spatially separated from the actuating element. The light guide element preferably extends from a surface located inside the electronic device to an externally visible surface of the electronic device / control unit, in particular to the touch surface. The control unit, in particular, includes the base element.Preferably, the actuating element, the triggering element, the resetting element and the light guide element are formed integrally, preferably monolithically, with the base element, wherein in particular the actuating element, the triggering element and the resetting element are spatially separated from the base element, but integrally, preferably monolithically, connected to the base element, and wherein in particular the light guide element is partially spatially overlapped with / formed through the base element.

[0006] If the push-button component is made of a plastic, preferably polycarbonate, cost-effectiveness, ease of manufacture, and / or a translucent appearance can be advantageously achieved. With a polycarbonate design, a monolithic integration of the light-guiding element with other parts of the control unit is advantageously possible. In this case, the control unit, particularly the actuating element itself, can advantageously possess light-guiding properties.

[0007] Furthermore, if the button component is made of a plastic that is at least partially transparent, preferably translucent, it is advantageous to integrate the light guide element monolithically with other parts of the control unit. A translucent material allows light to pass through partially, but is not completely transparent, so objects behind the material are only visible as blurred or indistinct shapes, if at all. The plastic of the button component is preferably translucent white or a single color. However, a two- or multi-colored design is also conceivable.

[0008] Furthermore, it is proposed that the trigger area and / or a designated light coupling area of ​​the light guide element be arranged on a side of the operating unit opposite the touch surface. This advantageously allows for a high degree of compactness and / or the most direct possible transmission of light and / or actuation movement. In particular, an advantageous design can be achieved. The light coupling area is specifically formed by a surface of the light guide element / button component which, when installed in the electronic device, is designed to be illuminated by a light source, so that a portion of the light from the light source enters the interior of the light guide element / button component and is propagated there (towards the touch surface).In particular, the (mean) surface normals of the sensing surface and the triggering surface point in directions that are at least substantially opposite to each other and preferably at least substantially parallel to each other. Specifically, the (mean) surface normals of the sensing surface and the surface of the light coupling area of ​​the light guide element point in directions that are at least substantially opposite to each other and preferably at least substantially parallel to each other. "Substantially parallel" here refers in particular to an alignment of a direction relative to a reference direction, especially in a plane, wherein the direction has a deviation from the reference direction of, in particular, less than 8°, advantageously less than 5°, and most advantageously less than 2°.The light is preferably generated by a light source, preferably an LED, located below the light coupling area / inside the electronic device. "Provided for" is understood to mean specifically programmed, designed, and / or equipped. The fact that an object is intended for a specific function is understood to mean, in particular, that the object fulfills and / or performs this specific function in at least one application and / or operating state.

[0009] Furthermore, it is proposed that the trigger area and / or the intended light coupling area of ​​the light guide element in the control unit be arranged laterally offset from the push button. This allows for design advantages. In particular, a low-profile design of the push button and / or the electronic device can be achieved, and / or space can be created / reserved for a component of the electronic device with a fixed minimum size, for example, an antenna of the electronic device. Additionally, an advantageous design of the circuit board of the electronic device can be achieved, and / or the integration of as many different components as possible into a single circuit board can be enabled. Specifically, the trigger area and the intended light coupling area are located next to each other, preferably at the same height relative to the base element.In particular, the trigger surface is located further out than the intended light coupling area. In particular, the trigger surface and the intended light coupling area are at least substantially parallel to each other. In particular, the trigger surface and the intended light coupling area are located on the same side of the operating unit when viewed relative to its center. In particular, the trigger surface and the intended light coupling area are located on a side opposite a support element of the operating unit when viewed relative to its center. In particular, the trigger surface and / or the intended light coupling area of ​​the light guide element are laterally offset from the touch surface when viewed from a normal direction of the touch surface, in particular on a plane of the operating unit other than a touch surface plane.

[0010] Furthermore, it is proposed that the operating unit has at least one support element for support against an edge and / or surface of the electronic device, in particular a housing part of the electronic device, which is arranged on a side of the operating unit opposite the trigger element, so that, in particular, the operating unit can perform a cantilever movement as a result of the actuation movement, at least pivoting the trigger element, preferably in a state mounted in the electronic device. This advantageously ensures simple assembly and / or reliable operation. The support element is formed integrally, in particular monolithically, with the remaining components of the push-button assembly.Preferably, the actuating element, the triggering element, the resetting element, the light guiding element and the base element are formed integrally, preferably monolithically, with the support element, wherein in particular the actuating element, the triggering element, the resetting element and the light guiding element are spatially separated from the base element, but integrally, preferably monolithically, connected to the base element, and wherein in particular the base element can partially overlap spatially with the support element / can be formed by the base element.

[0011] In this context, it is proposed that the support element be designed as a recess in the base element of the control unit, into which the edge and / or surface of the electronic device, in particular the housing part of the electronic device, which is designed as a tilting lug, can engage when mounted in the electronic device. This advantageously facilitates simple assembly. Furthermore, it advantageously simplifies precise assembly. It also advantageously reduces the risk of the control unit slipping or tilting due to an (incorrect) actuation movement. The recess forming the support element is bounded by the base element on at least two (opposite) sides, preferably at least three or exactly three sides, and preferably at least four or exactly four sides.The recess forming the support element has a shape corresponding to the outer shape of the tilting nose of the electronic device.

[0012] Furthermore, if the reset element is arranged on a side of the control unit opposite the support element and can generate a spring-elastic support of the control unit against the pivoting cantilever movement on a side of the control unit opposite the actuating element, preferably in the state when mounted in the electronic device, a reliable reset of the push button can advantageously be achieved. In particular, the reset element is arranged and designed such that it counteracts a pivoting of the control unit about the support element as a result of the actuating movement being applied to the button surface.

[0013] Additionally, it is proposed that the return element have a U-shape or C-shape, open in a direction parallel to a main extension direction of the control unit, particularly the base element. This allows for a simple design and / or reliable generation of the return force. The return element can be provided for support, when installed in the electronic device, against the circuit board of the electronic device, which is fixedly mounted within the device, or against a housing part of the electronic device. The return element can be pre-tensioned or mounted in a rest position within the electronic device. Preferably, it is mounted with a slight pre-tension. The U-shape resembles the capital letter U (e.g., in Arial font). The C-shape resembles the capital letter C (e.g., in Arial font).The term "principal extension direction" of an object is understood to mean, in particular, a direction that runs parallel to the longest edge of the smallest geometric cuboid that just completely encloses the object. The reset element is arranged, in particular, on a lateral side of the base element that is at least substantially perpendicular to the touch surface and follows an approximately 180° curve, so that its end is again aligned parallel to the principal extension direction of the control unit / base element. The term "substantially perpendicular" here is intended to define, in particular, an orientation of a direction relative to a reference direction, wherein the direction and the reference direction, especially when viewed in a projection plane, enclose an angle of 90° and the angle has a maximum deviation of, in particular, less than 8°, advantageously less than 5°, and most advantageously less than 2°.

[0014] Furthermore, it is proposed that the actuating element protrude from a base element of the operating unit, on which at least the reset element and the trigger element are also arranged, preferably at least substantially vertically, and have a circumferential receiving groove for a sealing element, particularly in a plane that runs at least substantially parallel to the tactile surface. This advantageously achieves basic water tightness of the electronic device at the location of the push button. Advantageously, a push button with IPX1 protection can be achieved. Advantageously, a secure hold of the sealing element in its intended position can be achieved.

[0015] Furthermore, it is proposed that the push-button device includes a sealing element made of a flexible-elastic material, e.g., rubber, which is designed to be compressed by a spring force of the return element when mounted in the electronic device. This advantageously allows IPX1 protection to be achieved. The sealing element is preferably compressed by the spring force of the return element, which is preferably pre-tensioned.

[0016] If the sealing element, when installed in the electronic device, is positioned between the base element of the control unit and a housing part of the electronic device, and is particularly compressed, water ingress via the push button can be advantageously prevented or made more difficult. The restoring force of the return element preferably squeezes the sealing element between the base element and the housing part.

[0017] Furthermore, it is proposed that the receiving groove and / or the sealing element have a circumferential contour in the shape of a superellipse or a square with rounded corners. This advantageously ensures a good seal. A close fit of the sealing element to the operating unit is also advantageously guaranteed. In particular, the shapes of the receiving groove and the sealing element correspond to each other.

[0018] Additionally, it is proposed that the trigger element and the reset element be arranged on the same side of a base element of the control unit and / or extend in directions parallel to each other. This allows for a high degree of compactness in the control unit. Advantageously, the reset element and the trigger element are arranged side by side and / or connected to the base element at adjacent locations. In particular, the main directions of extension of the reset element and the trigger element are at least substantially parallel to each other.

[0019] Furthermore, an electronic device, in particular an internet gateway and / or a radio module for remote control and / or remote monitoring of heating systems, preferably building heating systems, with one or more push-button devices, is proposed. This advantageously results in a more cost-effective and easier-to-install electronic device, especially with high reliability and / or service life.

[0020] The push-button device and the electronic device according to the invention are not to be limited to the application and embodiment described above. In particular, the push-button device and the electronic device according to the invention may, to fulfill a function described herein, have a different number of individual elements, components, and units than the number specified herein.

When mounted in the electronic device 10, the sealing element 46 is compressed / squeezed between the base element 38 of the control unit 12 and the housing part 36 of the electronic device 10.

[0028] The Fig. Figure 3 schematically shows a sectional view of a longitudinal section of the electronic device 10 running centrally through the actuating element 14.

[0034] The Fig. Figures 6a to 6c schematically show in three steps the assembly of the push button device 52 into the electronic device 10. First, the operating unit 12 is inserted from the side (along the arrow 64) into the housing part 36 of the electronic device 10 until the support element 34 engages with the tilting lug 40 (see Figure 6a to 6c). Fig. 6a). The operating unit 12 is then pivoted around the tilting nose 40 (along the arrow 66) so that the actuating element 14 enters the opening 56 of the housing part 36 (see figure). Fig. 6b). In this process, the sealing element 46, which has already been inserted into the receiving groove 44, is clamped between the housing part 36 and the base element 38 (see Fig. 6c).
