CONNECTING DEVICE FOR DETACHABLY CONNECTING TWO COMPONENTS

Description

[0001] The invention relates to an electronic device with a connecting device.

[0002] A connecting device has a closure module that can be fastened to a first of the assemblies and has a vacuum element that can be connected in an attachment direction to an attachment component of the other, second of the assemblies for connecting the assemblies and, in a connected position, interacts with the attachment component such that when the closure module and the attachment component are loaded relative to one another counter to the attachment direction, the vacuum element and the attachment component are held together due to a vacuum effect between the vacuum element and the attachment component.

[0003] In the present case, a connecting device is intended to be able to serve, in particular, for attaching an electronic device to an associated assembly. For example, the connecting device can enable the attachment of a camera to a helmet (e.g., a ski helmet or a bicycle helmet) or the attachment of a mobile phone or other electronic device in a vehicle, e.g., to the windshield or dashboard of a vehicle.

[0004] If a camera is attached to a helmet, such as a ski helmet or a bicycle helmet, or a mobile phone is attached to a vehicle dashboard or the handlebars of a bicycle, impulsive impact forces may occur during use. These must be absorbed and dissipated and, in particular, should not cause the camera or mobile phone to become detached. A connecting device for attaching an electronic device, such as a camera or a mobile phone, should therefore be particularly capable of absorbing short-term, impulsive impact forces.

[0005] For attaching very different assemblies to one another, for example, for attaching an electronic device in the form of a mobile phone or navigation device in a vehicle, connecting devices that provide a mount using negative pressure are known. For example, US 2013 / 0313388 A1 discloses a connecting device that uses a negative pressure element in the form of a suction cup to secure a mobile phone to the windshield of a vehicle. For this purpose, the suction cup is placed on the windshield, with a magnetic element arranged on the suction cup that can interact with a magnetic element on the windshield side to improve the hold on the windshield.

[0006] In a connecting device known from US 5,192,043 for attaching an alarm device to a metal surface, a magnetic rubber surface is applied to a metal surface, whereby a vacuum is created when the connection is made, so that the alarm device is held to the metal surface by the magnetic effect between the rubber surface and the metal surface as well as by negative pressure forces.

[0007] A connecting device known from EP 0 689 966 B1 has a magnetic contact plate on which a suction cup is arranged. Using the connecting device, a ski rack can be attached to the roof of a vehicle.

[0008] Such connecting devices should, on the one hand, be easy to close to establish a connection between the associated components. However, it is also desirable that such connecting devices be easy to open, in particular to prevent sudden tearing while overcoming a negative pressure and, if necessary, a magnetic connection.

[0009] US 5,076,527 describes a device for releasably connecting an object to a flat surface, for example, a mailbox or a lamp to an associated surface. The device has a vacuum element in the form of a suction cup, via which an attachment can be established.

[0010] From US 2016 / 0376065A1 an anchoring device for attaching a device, for example a liquid container, to a surface is known.

[0011] The object of the present invention is to provide a connecting device which is easy to use, in particular easy to close, but also easy to open again, with an advantageous connection of the associated components even under shock load.

[0012] This object is achieved by an article having the features of claim 1.

[0013] Preferred features are defined in claim 2.

[0014] An electronic device, in particular a camera or a mobile phone, has a connecting device for detachably connecting the electronic device to another assembly. The connecting device comprises a closure module with a vacuum element that can be connected in an attachment direction to an attachment component for connecting the electronic device to the other assembly and, in a connected position, interacts with the attachment component such that, when the closure module and the attachment component are loaded relative to one another counter to the attachment direction, the vacuum element and the attachment component are held together due to a vacuum effect between the vacuum element and the attachment component. The closure module is provided with a first magnetic element for magnetically supporting the connection of the electronic device to the other assembly.

[0015] The first magnetic element is attached to the vacuum element or to a component of the closure module connected to the vacuum element. Additionally, a second magnetic element is attached to the attachment component and interacts with the first magnetic element in such a way that magnetic attraction assists the attachment of the closure module to the attachment component.

[0016] The electronic device thus comprises a connecting device that enables a simple yet resilient connection of the electronic device to another assembly (for example, a helmet, in particular a sports helmet such as a ski helmet, or a vehicle, for example, a bicycle or a motor vehicle, for example, a dashboard in the interior of a motor vehicle). The electronic device is connected to the other assembly via the connecting device, the locking module of which interacts with the attachment component through both negative pressure and magnetic interaction, and is thus held in the connected position on the attachment component.

[0017] Due to the vacuum effect, shock loads, in particular, can be advantageously absorbed and dissipated, preventing the electronic device from becoming detached from the rest of the assembly. The magnetic interaction allows the connecting device to be easily closed, automatically creating a vacuum effect between the vacuum element and the attachment component.

[0018] The vacuum element has a cup element that is at least partially elastically designed or is formed by such a cup element. The vacuum element can thus be elastically deformed when the closure module is attached to the attachment component, which promotes a negative pressure effect between the vacuum element and the attachment component for a firm hold.

[0019] In one embodiment, the closure module has one or more electrical contact elements that serve to make electrical contact with one or more mating contact elements assigned to the attachment component when the closure module is attached to the attachment component with the connecting device closed. An electrical connection can thus also be established via the connecting device—in addition to a mechanical connection for holding the electronic device to an associated assembly. For example, currents for an electrical supply, for example, for charging the electronic device, can be transmitted via one or more electrical contact elements, or a data connection can be provided for exchanging data signals.

[0020] The closure module has, for example, an adjusting element which is adjustable relative to the vacuum element and which is movable relative to the vacuum element in order to release the vacuum element from the attachment component and to which the first of the assemblies is connectable in such a way that a relative movement between the first of the assemblies and the second of the assemblies causes a movement of the adjusting element.

[0021] The connecting device thus comprises an adjusting element that is arranged on the closure module and is adjustable relative to the vacuum element. The adjusting element enables the vacuum element to be released from the attachment component by operatively connecting the first assembly associated with the closure module to the adjusting element in such a way that movement of the first assembly relative to the second assembly results in movement of the adjusting element.

[0022] The first assembly can be implemented, for example, by an electronic device such as a camera or a mobile phone. The first assembly can be connected directly or indirectly to the adjustment element in such a way that a user can engage the first assembly, for example, the camera or mobile phone, to release the connecting device, thereby also moving the adjustment element and thus releasing the closure module from the associated attachment component.

[0023] With the connecting device, a connection is established between the assemblies to be fastened together by attaching the closure module connected to a first of the assemblies to an attachment component of the other, second of the assemblies (or vice versa, the attachment component to the closure module). During attachment, a sealed space is created between the vacuum element and the attachment component, so that the assemblies are held together by a vacuum effect. Such a connection can be particularly resilient to impact, so that impact forces can be absorbed and dissipated via the connecting device.

[0024] By means of the connecting device, for example, a camera can be attached to a helmet or a mobile phone can be attached to a vehicle, for example to a windshield or dashboard.

[0025] In the connected position of the connecting device, the vacuum element and the attachment component can, for example, lie flat against one another so that there is effectively no space between the vacuum element and the attachment component. However, when the assemblies are loaded relative to one another, a force can act on the closure module relative to the attachment component that acts to enlarge or create a space between the vacuum element and the attachment component, causing a vacuum between the vacuum element and the attachment component and thus generating holding forces that hold the vacuum element to the attachment component and tend to increase the greater the load on the closure module relative to the attachment component. The closure module is thus held to the attachment component due to the vacuum effect when the closure module is attached to the attachment component.

[0026] The closure module can have a flow opening that can be opened by moving the adjusting element relative to the vacuum element to allow air to flow into a space between the vacuum element and the attachment component. For example, in the connected position of the connecting device, the adjusting element can assume a first position relative to the vacuum element in which the flow opening is closed (viewed from the direction of a space between the vacuum element and the attachment component), preventing air from flowing into the space. From this first position, the adjusting element can be moved into a second position to open the flow opening and allow air to flow into a space formed between the vacuum element and the attachment component.Due to the inflow through the flow opening, there is no longer any negative pressure effect between the vacuum element and the attachment component, so that the closure module can be removed from the attachment component without any negative pressure effect.

[0027] In an advantageous embodiment, the adjusting element is spring-loaded toward its first position. The adjusting element thus automatically assumes its first position when not otherwise actuated and thus closes the flow opening, particularly in the connected position of the connecting device, so that a negative pressure effect can arise between the negative pressure element and the attachment component.

[0028] For this purpose, the locking module preferably has an elastic preload element that serves to preload the adjustment element toward the first position. During adjustment, the adjustment element is moved counter to the preloading effect of the preload element, so that after the end of the actuation, the adjustment element is automatically returned to its first position.

[0029] The vacuum element is formed by a cup element that is elastic at least in sections, and the attachment component is formed by an attachment surface formed on the second assembly, with which the vacuum element can be brought into contact to connect the assemblies and provide a vacuum effect. The vacuum element thus implements a component in the manner of an elastic suction cup that can be arranged on a surface of the associated second assembly to form a vacuum between the vacuum element and the surface under elastic deformation, thereby providing holding forces for holding the assemblies together.

[0030] The adjusting element can, for example, be moved to open a flow opening in the form of a valve, thus enabling air flow into a space between the vacuum element and the attachment component. Alternatively, it is also conceivable and possible that, by moving the adjusting element, the vacuum element in the form of a cup element is lifted from the surface, for example, in a direction perpendicular to the surface. Force-deflecting elements, for example, can create a separating force between the closure module and the attachment component.

[0031] In one embodiment, the adjustment element is guided on the vacuum element or on an element firmly connected to the vacuum element. The movement of the adjustment element relative to the vacuum element can occur along a straight or curved guideway, for example, a circular arc. The guided movement can, for example, open a flow opening to allow air flow between the vacuum element and the attachment component, thus eliminating a negative pressure effect between the vacuum element and the attachment component.

[0032] In principle, the adjusting element can be rotatable, displaceable, and / or tiltable relative to the vacuum element. For example, the adjusting element can be pivotally mounted on the vacuum element or on a component connected to the vacuum element as a flap element or a lever element. It can be pivoted relative to the vacuum element to expose a flow opening and thus eliminate a negative pressure effect between the vacuum element and the attachment component.

[0033] The first assembly is directly or indirectly connected to the adjustment element, so that a movement of the first assembly also leads to a movement of the adjustment element, in particular to the release of the closure module from the attachment component. If the first assembly is arranged directly on the adjustment element, the first assembly is firmly connected to the adjustment element, for example, by a screw connection. If the first assembly is indirectly connected to the adjustment element, the first assembly can, for example, be arranged on an actuating element that is operatively connected to the adjustment element in such a way that the adjustment element is also moved when the actuating element is actuated.The actuating element can, for example, be designed as a lever which, when pivoted, acts on the adjusting element and moves it so that, for example, a flow opening is released to cancel a negative pressure effect between the negative pressure element and the attachment component.

[0034] In a specific embodiment, the closure module has a cylinder part that is firmly connected to the vacuum element and guides the adjusting element. For example, the adjusting element can be located with a head section (with a circular cross-section) in a cylindrical cavity (with a circular cross-section) of the cylinder part and can be slidably adjusted along an inner surface of the cylinder part surrounding the cylindrical cavity. The adjusting element thus acts like a piston in the cylindrical cavity of the cylinder part, so that by adjusting the adjusting element in the cylindrical cavity of the cylinder part, the volume of the space between the vacuum element and the attachment component can be increased. During adjustment, the adjusting element is thus moved within the cylinder part and thereby slides within the cavity of the cylinder part.

[0035] In one embodiment, the adjusting element is guided relative to the cylinder part on a guideway extending along a section of a helix. The guideway can, for example, be formed on a guide part that has a circumferential surface extending around the cylinder part and is thus arranged radially outside the cylinder part. The guideway can be formed into the surface like a slotted guide, with a guide element of a housing part connected to the adjusting element being guided in the guideway, for example.

[0036] In this context, it is conceivable and possible to provide a single guideway along which the adjustment element is guided. However, it is also conceivable and possible to provide several circumferentially offset guideways, each of which engages a guide element of a housing part connected to the adjustment element, thus providing smooth, defined guidance of the adjustment element relative to the cylinder part, preventing any jamming between the adjustment element and the cylinder part.

[0037] The guideway extends along a section of a helix. Guided by the guideway, the adjustment element can be gradually moved axially during adjustment, along a helical line provided by the helix. A twisting movement of the adjustment element is thus translated into an axial movement along the cylinder axis of the cylinder part, allowing the adjustment element to be smoothly adjusted by screwing.

[0038] The adjustment element can preferably be sealed fluid-tight against the inner surface of the cylinder part via the head section located in the cavity of the cylinder part. For this purpose, the head section fits so precisely in the cavity of the cylinder part that air cannot flow past the head section. Thus, no air can flow past the head section into the space formed between the vacuum element and the attachment component, so that—without adjusting the adjustment element—the negative pressure in the space is maintained, reliably holding the assemblies together.

[0039] The head section can fit snugly into the cavity of the cylinder part. However, it is also conceivable and possible to provide a circumferential seal on the head section, for example, to seal the transition between the head section and the inner surface of the cylinder part.

[0040] In one embodiment, the flow opening is formed on the cylinder part. The flow opening is released when the adjusting element is adjusted from the first position, so that an air flow can flow between the vacuum element and the attachment component, thus canceling any negative pressure effect between the vacuum element and the attachment component. The flow opening functions as a valve that is closed when the vacuum element is attached to the attachment component, so that a negative pressure effect exists between the vacuum element and the attachment component. To open the connecting device, the flow opening can be opened by adjusting the adjusting element, so that an air flow from outside can flow between the vacuum element and the attachment component.This eliminates the holding forces of the connecting device, so that the assemblies connected to one another via the connecting device can be easily separated from one another.

[0041] The flow opening can be formed on the cylinder wall of the cylinder part at an axially recessed position, i.e., at a position arranged such that, when the vacuum element is attached to the attachment component, the head portion of the adjusting element lies between the flow opening and the attachment component, thus closing a flow path between the flow opening and a space between the attachment component and the vacuum element. Upon adjustment, the adjusting element slides within the cavity of the cylinder part and sweeps over the flow opening, opening a flow path between the vacuum element and the attachment component, allowing air to flow in.

[0042] In one embodiment, the locking module has an elastic preload element that serves to preload the adjustment element toward the first position. The adjustment element is thus held in the first position by a spring, for example, by a compression spring acting between the adjustment element and the cylinder part. During adjustment, the adjustment element is moved against the preloading effect of the preload element, so that after the end of the actuation, the adjustment element is automatically returned to its first position.

[0043] In one embodiment, an attachment assembly can be attached to the attachment component of the second assembly, for example in the form of a flat attachment surface. This attachment assembly has an attachment part with which the closure module can interact to connect the assemblies. The attachment assembly can improve the hold of the connecting device and, in particular, ensure a defined position between the closure module and the attachment component, in particular also to support transverse forces acting between the closure module and the attachment component.

[0044] For example, the adjustment element can have a first form-fitting section, and the attachment part can have a second form-fitting section. When the closure module and the attachment part are attached to one another, the form-fitting sections engage with one another in a form-fitting manner, preventing transverse movement between the closure module and the attachment component. The form-fitting sections can thus, in particular, prevent movement transverse to an attachment direction along which the closure module and the attachment component are attached to one another, so that forces acting in the transverse direction (i.e., forces acting in the plane of the attachment surface) can be absorbed and supported.

[0045] Additionally or alternatively, the locking module can also be secured in its rotational position via this attachment assembly, so that torsional forces can also be absorbed and supported. For this purpose, the vacuum element or an element connected to the vacuum element, for example, the cylinder part, can have a first engagement section, while the attachment part (on the other, second assembly) has a second engagement section. When the locking module and the attachment part are attached to one another, the engagement sections engage with each other in a locking manner, thus preventing any rotational movement of the vacuum element relative to the attachment part.

[0046] The engagement sections can be formed, for example, by a toothing (preferably running around a circular edge section) on the vacuum element or the element connected to the vacuum element on the one hand and the attachment part on the other hand.

[0047] In one embodiment, the closure module has a first magnetic element for magnetically supporting the connection of the assemblies to one another. This first magnetic element can, for example, be arranged on the adjustment element and is thus moved together with the adjustment element. Alternatively or additionally, a magnetic element can also be provided on the vacuum element or an element connected to the vacuum element, for example, the cylinder part.

[0048] A second magnetic element, in contrast, can be attached to the attachment component. Such a second magnetic element can, for example, be arranged on the attachment part and arranged together with the attachment part on the attachment component. The magnetic elements of the closure module, on the one hand, and of the attachment component, on the other hand, serve to provide a magnetic attraction force when the closure module and the attachment component are attached to one another, so that the negative pressure is created in a magnetically assisted manner (preferably automatically). During attachment, the closure module and the attachment component are magnetically attracted to one another due to the magnetic interaction, so that a (near) vacuum is created between the negative pressure element and the attachment component, for example by pressing the negative pressure element, designed as an elastic cup element, against the attachment component, designed as an attachment surface.

[0049] If the first magnetic element is arranged on the adjustment element, the first magnetic element moves along with the adjustment element when the adjustment element is adjusted. This allows it to be moved away from the second magnetic element on the side of the attachment component, thus weakening the magnetic attraction forces. Adjusting the adjustment element also at least weakens the magnetic holding forces, which can contribute to a simple, smooth, and pleasant-to-the-touch opening process.

[0050] The first magnetic element and the second magnetic element can each be formed by a permanent magnet or an arrangement of several permanent magnets and, to close the connecting device, interact in a magnetically attractive manner by facing each other with opposite magnetic poles. However, it is also conceivable for one magnetic element to be formed by a permanent magnet or an arrangement of several permanent magnets, while the other magnetic element is formed by a magnetic armature made of a ferromagnetic material.

[0051] In one embodiment, the closure module has one or more electrical contact elements which serve to make electrical contact with one or more mating contact elements assigned to the attachment component when the closure module is attached to the attachment component with the connecting device closed. An electrical connection can thus also be established via the connecting device - in addition to a mechanical connection for holding assemblies together - which can be particularly advantageous if, for example, an electronic device is to be attached to an assigned assembly via the connecting device. In this case, currents for an electrical supply, for example for charging the electronic device, can be transmitted via one or more electrical contact elements, or a data connection for exchanging data signals can be provided.

[0052] 12 The connecting device is designed to attach an electronic device to an associated assembly. For example, the connecting device can be used to attach a camera to a helmet, such as a ski helmet or a bicycle helmet. In another embodiment, the connecting device can also be used to attach a mobile phone or a navigation device or another electronic communication or information device in a vehicle, for example, to a windshield or a dashboard.

[0054] Fig. 1A , 1B bis 6A-6C show a first embodiment of a connecting device 1, which—in the illustrated embodiment—serves to attach an electronic device in the form of a camera 4 to a helmet 5 (e.g., a ski or bicycle helmet). The camera 4 can be detachably connected to an attachment surface 50 of the helmet 5 via the connecting device 1, so that, for example, video recordings can be made while the helmet 5 is in use.

[0055] The connecting device 1 has a closure module 2 that can be attached to an attachment assembly 3 on the side of the helmet 5. The closure module 2 consists of a plurality of interacting parts and is attached to the camera 4. The connection of the closure module 2 to the camera 4 can (likewise) be detachable, for example, to enable the connecting device 1 to be used on different electronic devices.

[0056] The closure module 2 has a housing part 20 which is cylindrically shaped and is firmly connected via fastening points 201 to an adjusting element 23 which is received centrally in the housing part 20.

[0057] The adjusting element 23 has a shaft 230 and a fastening point 231 arranged thereon, via which the adjusting element 23 is fixed to the housing part 20. At an end facing away from the bottom of the housing part 20, the adjusting element 23 has a head portion 232 that projects radially outward beyond the shaft 230.

[0058] The housing part 20 and the adjustment element 23, which is connected to the housing part 20 in a rotationally fixed manner, are firmly connected to the camera 4.

[0059] For example, the section view according to Fig. 2C can be removed, the adjusting element 23 lies in a cylindrical cavity 253 of a cylinder part 25 such that the head section 232 is slidably guided on an inner surface 250 of the cylinder part 25. The cylinder part 25, which is cylindrical with a circular cross-section, is fixedly connected to a guide part 21 which has an opening 212 through which the adjusting element 23 engages with its shaft 230. A collar 213 projects axially from a base of the guide part 21 facing the base of the housing part 20, into which collar the cylinder part 25 engages and via which the cylinder part 25 is fixedly connected to the guide part 21 (for example by welding or gluing).

[0060] The guide part 21 also has a cylindrical basic shape, with a cylindrical outer surface 210 that extends circumferentially around the cylinder part 25 accommodated within the guide part 21 and is thus arranged radially outside the cylinder part 25. A plurality of circumferentially offset, parallel, helical guideways 211 are formed on the outer surface 210. These guideways are formed as slotted guides in the outer surface 210 and engage with guide elements 202 in the form of pins on the housing part 20 (projecting radially inward from a outer surface 200 of the housing part 20).Due to the engagement of the guide elements 202 of the housing part 20 in the guide tracks 211 of the guide part 21, the housing part 20 (and above it also the adjusting element 23) is positively guided on the guide part 21 about a rotation axis R, so that when the housing part 20 is rotated about the rotation axis R, the structural unit formed from the housing part 20 and the adjusting element 23 follows the helical guide tracks 211 and thereby the adjusting element 23 is moved axially within the cylinder part 25.

[0061] The cylinder part 25 is firmly connected to a vacuum element 27 in the form of an elastic cup element 27, in that the cylinder part 25 engages in a collar 270 of the vacuum element 27 and is clamped to the vacuum element 27 via a circumferential tension spring 26. The vacuum element 27 is thus firmly connected, in particular also fluid-tight, to the cylinder part 20.

[0062] The adjusting element 23 is pre-tensioned relative to the guide part 21 and thus relative to the cylinder part 25 by means of a pre-tensioning element in the form of a compression spring 22 which surrounds the shaft 230, in the direction of the Fig. 2C shown starting position. In the starting position, the head portion 232 of the adjusting element 23 thus lies at an end of the cylinder part 25 that faces away from the guide part 21. In this position, the guide part 21 is retracted to its maximum extent into the housing part 20.

[0063] The attachment surface 50 on the helmet 5 serves for attaching the vacuum element 27 in the form of a cup element. The attachment assembly 3 with an attachment part 30 and a magnetic element 31 received in a receiving opening 302 of the attachment part 30 is arranged on the attachment surface 50 of the helmet 5. The shutter module 2 for connecting the camera 4 to the helmet 5 is attached to this attachment assembly 3.

[0064] The closure module 2 has a magnetic element 24, which is received in a receiving opening 234 of the adjustment element 23 and which, when the closure module 2 is attached to the attachment surface 50, interacts with the magnetic element 31 of the attachment assembly 3 in a magnetically attractive manner, so that the closure module 2 (with the camera 4 arranged thereon) is magnetically attracted to the attachment assembly 3 of the helmet 5. On the adjustment element 23, on the side of the head section 232 facing away from the housing part 20, a form-fitting section 233 in the form of a conical recess is formed, which, when the closure module 2 is attached, engages with an associated form-fitting section 300 in the form of a conical elevation on the attachment part 30, so that the closure module 2 is attached to the attachment assembly 3 of the helmet 5 in a defined manner.

[0065] The positive locking between the positive locking sections 233, 300 serves to advantageously absorb transverse forces in the plane of the attachment surface 50 when the connecting device 1 is closed. Furthermore, the closure module 2 engages the attachment assembly 3 in a centered manner via the positive locking.

[0066] When the closure module 2 is attached to the attachment surface 50, as can be seen from the transition from Fig. 2A-2C towards Fig. 3A-3C As can be seen, the vacuum element 27 is elastically deformed at a cup-shaped edge portion 272 projecting radially beyond the cylinder part 25, whereby air escapes from a space B formed between the vacuum element 27 and the attachment surface 50, and thus, when the closure module 2 is loaded, a suction vacuum acts between the vacuum element 27 and the attachment surface 50. In this way, impulsive impact forces can be absorbed and dissipated at the connecting device 1 when the helmet 5 is in use, so that the camera 4 is held securely and reliably on the helmet 5 even under impact loads.

[0067] On a circumferential edge of the cylinder part 25 facing the attachment part 30, an engagement section 252 in the form of a toothing is formed, which, when the closure module 2 is attached to the attachment assembly 3, engages positively with a circumferential engagement section 301 in the form of a toothing on the attachment part 30, as can be seen from a synopsis of Fig. 2C and 3C and Fig. 1A and 1B can be seen. In this way, the cylinder part 25 and, above it, the guide part 21 and the vacuum element 27 are fixed in a rotationally fixed manner to the attachment assembly 3 and thus to the helmet 5, so that torsional forces acting on the vacuum element 27 can also be effectively absorbed and dissipated.

[0068] In the connected position, the camera 4 is thus rigidly attached to the helmet 5 via the connecting device 1.

[0069] To open the connecting device 1, as shown in Fig. 4A bis 4C shown, the camera 4 and above it also the housing part 20 and the adjustment element 23 connected thereto are rotated in a direction of rotation D about the rotation axis R relative to the cylinder part 25. Due to the engagement of the engagement sections 252, 301 on the side of the cylinder part 25 and the attachment part 30, it is ensured that the cylinder part 23 cannot rotate during this rotational movement and thus the adjustment element 23 is moved within the cylindrical cavity 253 of the cylinder part 25.

[0070] By rotating the housing part 20 and by guiding the housing part 20 on the guide part 21, the adjusting element 23 is adjusted axially along the rotation axis R within the cylinder part 25 and thus, as can be seen from Fig. 4C visible, from the attachment part 30. This causes, on the one hand, that the magnetic elements 24, 31 are moved away from each other, so that the magnetic attraction between the magnetic elements 24, 31 is weakened. And, on the other hand, this causes the head section 232 to slide within the cavity 253 and to sweep over a flow opening 251 in the wall of the cylinder part 25, so that an air flow F can flow into the space B through the flow opening 251 and a negative pressure in the space B is thus equalized. The holding force caused by the negative pressure element 27 is thus canceled out, so that - as in Fig. 5A bis 5C shown - the edge section 272 of the vacuum element 27 is lifted from the attachment surface 50 and - as in Fig. 6A bis 6C shown - the shutter module 2 together with the camera 4 can be removed from the attachment surface 50.

[0071] The helical guide of the housing part 20 on the guide part 21 allows for easy adjustment of the adjustment element 23. Releasing the connecting device 1 can thus be haptically pleasant and comfortable for a user, while the connecting device 1 can withstand high loads in the connected position.

[0072] Once the closure module 2 has been separated from the attachment assembly 3, the adjustment element 23 returns to its original position due to the preloading effect of the preloading element 22 in the form of a compression spring, rotating the cylinder part 25 and the adjustment element 23 relative to each other. The closure module 2 can thus be reattached to the attachment assembly 3 if desired.

[0073] When the connecting device 1 is connected, a fluid-tight separation is created between the flow opening 251 and the space B formed between the vacuum element 27 and the attachment surface 50 via the head section 232, which lies (largely) fluid-tight in the cavity 253 of the cylinder part 25. By adjusting the adjusting element 23 within the cavity 253, this flow opening 251 comes into flow connection with the space B, so that air can flow into the space B and the connecting device 1 can thus be separated.

[0074] A negative pressure between the vacuum element 27 and the contact surface 50 is particularly effective in the case of sudden, short-term loads. When the closure module 2 is subjected to a load (e.g., tensile load), a force acts in the direction of enlarging the space B, which leads to a negative pressure in this space B. The vacuum element 27, which forms a flat seal against the contact surface 50, can thus effectively absorb particularly sudden loads.

[0075] Additionally, a hold is provided by the magnetic elements 24, 31, so that the closure module 2 is also held magnetically to the attachment assembly 3. The magnetic elements 24, 31 additionally support the attachment of the closure module 2 and the attachment assembly 3 to each other, pressing the vacuum element 27 against the attachment surface 50.

[0076] Because the negative pressure created between the vacuum element 27 and the attachment surface 50 is particularly effective during impact loads, the connecting device 1 can also ensure emergency detachment under larger, longer-lasting loads. For example, if a (predetermined) limit force is exceeded, the camera 4 can be torn off the helmet 5, releasing the vacuum element 27 from the attachment surface 50. For this purpose, the vacuum element 27 and the vacuum force applied to the vacuum element 27 can be dimensioned accordingly.

[0077] In another embodiment, shown in Fig. 7A bis 7C , the connecting device 1 serves to attach a mobile phone 5 or another electronic device (for example, a navigation device), for example, in a vehicle, for example on the dashboard or on the windshield of the vehicle. In this case, the attachment assembly 3 is arranged according to the invention on a housing surface of the mobile phone 5 or the other electronic device serving as an attachment surface 50, while the closure module 2 can be arranged on the vehicle, for example by at least partially integrating the closure module 2 into a dashboard and thus recessing it.

[0078] Otherwise, the embodiment is as per Fig. 7A bis 7C identical to that described above, so reference should be made to the above explanations in full.

[0079] In a Fig. 8A , 8B bis 10A-10C In the illustrated embodiment of a connecting device 1, a closure module 2 is to be attached to an attachment component 50 in the form of an attachment surface on an electronic device 5 or another assembly.

[0080] The closure module 2 has a vacuum element 27, which has a flexible edge portion 272 and is to be connected to the attachment component 50 in the form of the attachment surface on the assembly 5 by means of the flexible edge portion 272, subjected to elastic deformation to provide a vacuum effect. The flexible edge portion 272 extends circumferentially as a cup element around a body 273, on which a flow opening 274 is formed and on which an adjustment element 23 in the form of a flap element is articulated via bearing elements 275 and an axle element 276.

[0081] Additionally, an actuating element 28 is arranged on the axle element 276, which interacts with the adjusting element 23 in the form of the flap element in order to actuate the adjusting element 23 to release the closure module 2 from the attachment component 50.

[0082] For example, Fig. 9A und Fig. 9C As can be seen, the actuating element 28 is guided by a spring element 280 in the form of a tension spring in the direction of Fig. 9A-9C In addition, the adjusting element 23 is spring-loaded into the position shown in Fig. 9A-9C shown closed position is spring-loaded, in which the adjusting element 23 closes the flow opening 274 in the body 273 of the vacuum element 27 in a fluid-tight manner with a closing element 235 in the form of a pin engaging in the flow opening 274, so that in particular no air can flow through the flow opening 274 between the vacuum element 27 and the attachment component 50.

[0083] In the Fig. 9A-9C In the position shown, in which the closure module 2 is attached to the attachment component 50 of the assembly 5, there is a negative pressure effect between the negative pressure element 27 and the attachment component 50. Due to this negative pressure effect, the closure module 2 is held on the attachment component 50, so that the closure module 2 cannot be easily removed from the attachment component 50, at least not without removing the negative pressure effect.

[0084] Fastening points 283, for example, in the form of screw holes, are provided on the actuating element 28, via which the actuating element 28 can be connected to an associated, further assembly. For example, the actuating element 28 can be secured to a vehicle, for example to a dashboard of a motor vehicle, in order to (removably) secure an assembly 5, for example, an electronic device in the form of a mobile phone or the like, to the vehicle.

[0085] To release the closure module 2 from the attachment component 50, the adjustment element 23 is adjusted by actuating the actuating element 28, so that the flow opening 274 is released and an air flow can flow through the flow opening 274 between the vacuum element 27 and the attachment component 50, as shown in Fig. 10A-10C is shown. A negative pressure effect between the negative pressure element 27 and the attachment component 50 is thus eliminated, so that no holding forces act between the closure module 2 and the attachment component 50 (anymore).

[0086] For actuation, the actuating element 28 is tilted about the axis element 276 relative to the vacuum element 27, as can be seen from Fig. 10A-10C can be seen. As a result, the actuating element 28 acts on the adjusting element 23 with a section 281 remote from the head end 282 and also pivots the adjusting element 23 about the axis element 276. The adjusting element 23 is thus moved—indirectly via the actuating element 28—out of its closed position and releases the flow opening 274, so that the closure module 2 can be released from the attachment component 50.

[0087] When the actuating element 28 is actuated, the spring element 280 is tensioned, as can be seen from Fig. 10A-10C can be seen. In addition, the pre-tensioning element 22 is tensioned under pressure. After the actuation is completed, the actuating element 28 and the adjusting element 23 return to their respective starting positions due to the spring action, shown in Fig. 9A-9C , so that when the actuating element 28 is not actuated, the flow opening 274 is closed and the vacuum element 27 can thus be attached to an attachment component 50 to reconnect the closure module 2.

[0088] In the embodiment according to Fig. 8A , 8B bis 10A-10C Magnetic elements can be arranged on the one hand on the closure module 2 and on the other hand on the attachment component 50 to magnetically support the attachment of the closure module 2 to the attachment component 50. However, this is not mandatory. The connecting device 1 can also be non-magnetic and hold the closure module 2 to the attachment component 50 solely due to the negative pressure effect.

[0089] In a Fig. 11A , 11B bis 13A-13C illustrated embodiment is, in contrast to the embodiment according to Fig. 8A , 8B bis 10A-10C , an adjusting element 23 is slidably arranged on a vacuum element 27 of a closure module 2 of a connecting device 1. The vacuum element 27 in turn has a flexible, elastically deformable edge section 272 in the form of a cup element, with which the vacuum element 27 can be attached to a flat attachment component 50 of an assembly 5 in order to be in the attached position ( Fig. 12A-12C ) to hold the closure module 2 on the attachment component 50 due to a negative pressure effect.

[0090] In this embodiment, an adjusting element 23 is guided on a body 273 of the vacuum element 27 so as to be displaceable along a guide direction extending transversely to an attachment direction A, in that the adjusting element 23 engages with a guide piece 236 in an associated guide device 277 on the body 273 of the vacuum element 27.

[0091] In a starting position, shown in Fig. 12A-12C , the adjusting element 23 closes a flow opening 274 in the body 273 with a closing element 235 in the form of a pin, so that a negative pressure effect exists between the negative pressure element 27 and the attachment component 50 for holding the closure module 2 to the attachment component 50 when the closure module 2 is attached to the attachment component 50. In particular, when the flow opening 274 is closed, an inflow of air between the negative pressure element 27 and the attachment component 50 via the flow opening 274 is prevented.

[0092] To release the closure module 2 from the attachment component 50, the adjustment element 23 can be moved transversely to the attachment direction A on the body 273 of the vacuum element 27, as shown in Fig. 13A-13C As a result, a preloading element in the form of a compression spring acting between the adjusting element 23 and the vacuum element 27 is subjected to pressure, and the flow opening 274 is released, so that an air flow can flow between the vacuum element 27 and the attachment component 50, thus canceling out any vacuum effect between the vacuum element 27 and the attachment component 50.

[0093] After the actuation has been completed, the adjusting element 23 is automatically returned to the starting position according to the pressure effect of the pre-tensioning element 22. Fig. 12A-12C reset, so that in the initial position when the adjusting element 23 is not actuated, the flow opening 274 is again closed and the closure module 2 can thus be attached again to an associated attachment component 50 of an assembly 5.

[0094] The adjustment element 23 has fastening points 283, via which an associated assembly can be attached to the adjustment element 23. The adjustment element 23 is thus actuated by a relative movement between the assembly connected to the adjustment element 23 and the assembly 5 to which the closure module 2 is attached. For example, a user can grasp the assembly 5 in order to move the adjustment element 23 toward the vacuum element 27 and thus detach the assembly 5 from the closure module 2.

[0095] The assembly 5 can, for example, be an electronic device in the form of a mobile phone or the like. The adjustment element 23, on the other hand, can be fixed to a vehicle, for example, to a dashboard of a motor vehicle, so that the assembly 5 can be releasably attached to the vehicle via the connecting device 1.

[0096] In the embodiments described so far, the vacuum element is designed as an elastic cup element. However, this is not mandatory. In principle, rigid, non-elastic elements can also cooperate to create a vacuum and thus provide a holding force, although this is not within the scope of the present invention.

[0097] This is exemplified in a schematic representation of an embodiment in Fig. 14 shown.

[0098] The connecting device 1 has a closure module 2 that can be attached to an assembly 5. Thus, the closure module 2 of the connecting device 1, which is rigid and inelastic, can, for example, be precisely inserted into an attachment component 50 in the form of an opening 500 formed in the assembly 5, so that the cylinder part 23 is received in a substantially fluid-tight manner within the opening 500. When the closure module 2 is loaded, a negative pressure is created between the cylinder part 25 and the walls of the opening 500, so that the closure module 2 is secured to the assembly 5.An adjusting element 23 adjustable within the cylinder part 25 can be adjusted in a manner analogous to that described above in order to release the connecting device 1 by opening a flow path between a flow opening 251 in the cylinder part 25 and a space formed between the cylinder part 25 and the walls of the opening 500, so that air can flow into the space and the cylinder part 25 can thus be removed from the opening 500.

[0099] The cylinder part 25 can be inserted precisely into the opening 500, thus creating a fluid-tight transition between the cylinder part 25 and the walls of the opening 500. The outer shape of the cylinder part 25 can be circular-cylindrical, although the cylinder part 25 can also have a different outer shape, for example, a polygonal outer shape or any other cross-sectional shape.

[0100] In addition, it is also conceivable and possible, for example, to provide one or more circumferential sealing rings in the form of sealing lips or the like on the outside of the cylinder part 25, which seal the transition between the cylinder part 25 and the walls of the opening 500 in a fluid-tight manner.

[0101] Fig. 15A , 15B bis 19A-19C show an embodiment of a container in the form of a drinking bottle, in which a container body 51 of an assembly 5 can be connected to a lid 29 in order to close the container body 51. The lid 29 is part of a closure module 2 of a connecting device 1, via which the lid 29 can be firmly but detachably connected to the container body 51.

[0102] The connecting device 1 is formed by the closure module 2, of which the lid 29 is a component, and an attachment assembly 3 with an attachment part 30, which is to be connected to the container body 51 via a thread 501. The attachment part 30 has a form-fitting section 300 in the form of a protruding pin piece, which has a central opening through which a user can drink from the drinking bottle, for example, when the lid 29 is removed.

[0103] The cover 29 of the closure module 2 forms, together with a flexible, circumferential edge section 272, a vacuum element 27 which can be attached to the attachment part 30 of the attachment assembly 3 in an attachment direction A and in the attached position ( Fig. 17A-17C ) is held on the attachment part 30 under negative pressure. On the inside of the lid 29, an engagement opening 256 is formed, into which the form-fitting section 300 of the attachment part 30 engages when the closure module 2 is attached. A seal 254 in the form of an O-ring is arranged on the inner surface of the engagement opening 256, which seals off a transition between the lid 29 and the form-fitting section 300 in a fluid-tight, in particular moisture-tight, manner, so that liquid cannot penetrate out of the container 50 when the lid 29 is attached to the container body 51.

[0104] On a surface 304 facing the cover 21, the attachment part 30 has receiving openings 302 into which magnetic elements 31 are inserted and connected to the attachment part 30. Likewise, receiving openings 255 are formed on the inside of the cover 29, into which magnetic elements 24 are inserted and thus held on the cover 29.

[0105] The magnetic elements 31 on the attachment part 30, on the one hand, and the magnetic elements 24 on the cover 29, on the other hand, are evenly distributed and alternately polarized, viewed circumferentially around the attachment direction A. A magnetic element 31 of the attachment part 30 thus points with a north pole N toward the cover 29, while adjacent magnetic elements 31 each point with a south pole S toward the cover 29 and then again follow north poles N. Likewise, a magnetic element 24 of the cover 29 points with a south pole S toward the attachment part 30, while adjacent magnetic elements 24 each point with a north pole N toward the attachment part 30 and then again follow south poles S.

[0106] When the lid 29 is placed on the attachment part 30 to close the drinking bottle, unlike poles of the magnetic elements 24, 31 attract each other, so that the lid 29 is pulled towards the attachment part 30, the form-fitting section 300 engages with the engagement opening 256 and, with elastic deformation of the flexible edge section 272, a negative pressure effect is provided between the lid 29 and the attachment part 30 (see the transition from Fig. 16A-16C towards the position set out in Fig. 17A-17C ). In the attached position ( Fig. 17A-17C ), the cover 29 is thus held on the attachment part 30 on the one hand due to the magnetic attraction between the magnetic elements 24, 31 and also due to the negative pressure effect.

[0107] To release the lid 29 from the attachment part 30 and thus from the container body 51, the lid 29 can be rotated along an opening direction O, along which the lid 29 is rotatable about a rotation axis R defined by the engagement of the form-fitting section 300 in the engagement opening 256 relative to the attachment part 30, whereby the magnetic elements 24, 31 with like-like poles are brought closer together and thus a magnetic repulsion is created between the magnetic elements 24, 31. This magnetic repulsion can weaken or even exceed the negative pressure effect between the lid 29 and the attachment part 30, so that the lid 29 can be easily released from the attachment part 30 in the opposite direction to the attachment direction A, and the drinking bottle can thus be opened. This is in the transition from Fig. 18A-18C towards Fig. 19A-19C This rotation can also open a flow opening.

[0108] A connection of a lid 29 with a container 5 of the type described is not only conceivable and possible with a drinking bottle, for example for use on a bicycle, but can also be used with completely different, arbitrary containers that can be closed with a lid.

[0109] Fig. 20A-20C and 21A-21C show an embodiment of a connecting device 1 having a closure module 2 with a vacuum element 27, which can be attached in an attachment direction A to an attachment part 30 of an attachment assembly 3 connected to an assembly 5. A further assembly can be connected to the vacuum element 27, so that the assembly 5, for example an electronic device in the form of a mobile phone, can be arranged on the further assembly via the connecting device 1.

[0110] The vacuum element 27 has a flexible edge section 272 in the form of a cup element. Furthermore, a magnetic element 24 is arranged on a body 273, which magnetically interacts with a magnetic element 31 on the attachment part 30 of the attachment assembly 3 when the closure module 2 is attached to the attachment assembly 3, thus magnetically supporting the attachment of the closure module 2 to the attachment assembly 3.

[0111] In attached position ( Fig. 21A-21C ) there is a negative pressure effect between the negative pressure element 27 of the closure module 2 and an attachment component 50 of the assembly 5, on which the attachment assembly 3 is arranged, due to elastic deformation of the flexible edge section 272 and creation of a (near) vacuum between the negative pressure element 27 and the attachment component 50.

[0112] In this embodiment, the closure module 2 is released from the attachment assembly 3 by pulling or tilting the vacuum element 27.

[0113] In the illustrated embodiment, electrical contact elements 6 are arranged on the closure module 2, which, when the closure module 2 is attached to the attachment assembly 3, make electrical contact with associated counter-contact elements 7 on the side of the attachment assembly 3, as can be seen from Fig. 20C in conjunction with Fig. 21C can be seen. Via the contact elements 6 and the counter-contact elements 7, an electrical connection can thus be established between the assembly 5 assigned to the attachment assembly 30 and an assembly assigned to the closure module 2, for example in order to provide an electrical supply or a data connection.

[0114] In the illustrated embodiment, the electrical contact elements 6 have contact pins 61, which are elastically supported on the body 273 of the vacuum element 27 via spring elements 62 and are connected to electrical lines 60. The counter-contact elements 7, on the other hand, can be designed, for example, as contact pads or the like on an upper side of the attachment part 30 facing the vacuum element 27, so that in a position where the closure module 2 ( Fig. 21A-21C ) the contact elements 6 make electrical contact with the mating contact elements 7.

[0115] One in Fig. 22A-22C bis 24A-24C The illustrated embodiment is identical to that shown in Fig. 1A , 1B bis 6A-6C described embodiment, wherein additionally on the closure module 2 on the one hand and on the attachment assembly 3 on the other hand electrical contact elements 6 are arranged, which when the closure module ( Fig. 24A-24C ) can electrically contact one another and thus establish an electrical connection between the modules assigned to the connecting device 1, for example for an electrical supply of a module 5, for example an electronic device in the form of a mobile phone, or for providing a data connection.

[0116] Otherwise, the example should be as per Fig. 22A-22C bis 24A-24C to the example according to Fig. 1A , 1B bis 6A-6C Executed are referred to. Bezugszeichenliste
