Description

[0001] The invention relates to a building closure or fence closure drive device, in particular a door or gate drive device.

[0002] From EP 1 025 328 B1, a so-called sliding drive for operating a garage door leaf is known. The sliding drive comprises a motor drive unit and a guide rail connected to it. A carriage, which is movable in the guide rail, is connected to a door leaf. Such a sliding drive can also be controlled by means of a wired connection or a wireless remote control device.

[0003] From EP 1 297 235 B1, a drive device for entrance gates and the like is also known. The drive device comprises a drive unit for operating a building or perimeter gate. Such a drive device can also be wirelessly remotely controlled.

[0004] From DE 10 2008 034 497 A1 a hand transmitter for a gate drive system comprising at least one gate drive is known, wherein the hand transmitter is equipped with an acceleration, motion and tilt sensor such that different signals can be sent from the hand transmitter by different hand movements.

[0005] DE 10 2011 090 139 A1 discloses a transmitter arrangement for a radio station for an access system for a portable radio key for locking and unlocking motor vehicles. The transmitter arrangement comprises an antenna structure with a conductor structure designed as a flat, sheet metal stamping.

[0006] EP 2 348 575 A1 discloses a radio transmitter arrangement for control elements of a home installation arrangement, wherein the radio transmitter arrangement has an antenna which is designed as a conductor track on a printed circuit board.

[0007] EP 0 913 979 A2 discloses a method for operating a mobile phone, wherein the mobile phone is operated as a remote control for a garage door and the mobile phone is switched to an operating state in which no connection to a station of the mobile network is established.

[0008] The drives described above are similar to those in the Fig. 1, Fig. 2 to Fig. Figure 3 shows a drive device 10, which comprises a motor drive unit (not shown) and a receiver 12 for receiving radio signals from a remote control device. The receiver 12 is equipped with a wire antenna 14, also called a throw antenna. The receiver 12 can be part of a transceiver 16.

[0009] The wire antenna 14 must be precisely dimensioned. Furthermore, its assembly requires a complex and error-prone manual process. In particular, wire bending, alignment, and the potential for the wire antenna 14 to become pinched are critical. Correct alignment of the wire antenna 14 may require several tests and adjustments. An additional cover 17 and an end cap 18 protect the wire antenna 14 from unintentional contact with other components of the drive unit 10.

[0010] Previously, the wire antenna 14 in such building closure or fence closure drive devices 10 was manually cut to length, installed, and aligned. The manufacture of these building closure or fence closure drive devices 10 is therefore prone to errors, complex, and expensive.

[0011] The invention aims to improve building closure or fence closure drive devices, in particular in such a way that their manufacture is less complex and less prone to errors.

[0012] The problem is solved by a building closure or fence closure drive device according to claim 1. Advantageous further developments of the drive device are the subject of claims 2 to 15.

[0020] It is preferred that the antenna is attached to a support element of the receiving device with at least one of its connection areas.

[0021] It is preferred that the receiving device or the transmitting receiver comprises a circuit board having a first side populated with components and a second side without components, wherein a) the antenna is arranged on the first side and in particular runs essentially orthogonally to the plane of the circuit board or b) the antenna is located on the second side and, in particular, runs essentially in the plane of the circuit board.

[0022] It is preferred that the antenna has a coating selected from the following material group: a) paint b) electrically insulating varnish c) Tin.

[0025] It is preferred that the second transmitting device be part of a second transceiver designed for bidirectional communication.

[0026] It is preferred that the second antenna is designed in a bow shape and has a first connection area designed for tapping and / or feeding in a radio signal, a second connection area designed as a ground connection and a connection area that electrically connects the two connection areas to each other.

[0027] It is preferred that the second antenna is designed to receive and / or transmit radio signals with different carrier frequencies.

[0028] It is preferred that the second antenna has a third connection area designed for setting the carrier frequency, which is electrically connected to the connection area.

[0029] It is preferred that, in the second antenna, the first connection area is arranged between the second and third connection areas.

[0030] It is preferred that the connection area of ​​the second antenna has a first section arranged between the first connection area and the second connection area and a second section arranged between the first connection area and the third connection area. wherein the second section in one dimension has an extent that is between 2 times and 20 times, in particular 2.5 times and 10 times, the extent of the corresponding dimension of the first section.

[0035] Such a building termination or fence termination drive device offers several advantages, including the following: The antenna, formed from a sheet metal element or a section of conductive track, can be easily populated like other components (capacitors, resistors, ICs, etc.). There is no need for complex adjustments to wire dimensions to match the corresponding radio frequencies. Assembly errors are virtually eliminated thanks to the robust construction and simple bracket design. Subsequent adjustment or alignment of the antenna is also unnecessary. The use of inexpensive sheet metal or conductive track material further reduces manufacturing costs. Using air as the dielectric reduces transmission and / or reception losses. Another advantage is that adapting to different carrier frequencies does not require the fabrication and installation of a new antenna.Instead, adjusting the frequency-determining components of the receiving device, such as capacitors or inductors, is usually sufficient to set the carrier frequency. This makes the building termination or fence termination drive device, according to the present invention, less complex and less prone to errors in its manufacture.

[0036] Exemplary embodiments of the invention are explained in more detail below with reference to the accompanying drawings. These show: Fig. 1 an interior view of a drive device according to the state of the art; Fig. 2 an enlarged interior view of the drive device Fig. 1; Fig. 3 a state-of-the-art transceiver; Fig. 4 an embodiment of a building closure or fence closure drive device; Fig. 5 an interior view of the building closure or fence closure drive device Fig. 4; Fig. 6 an enlarged view of the building closure or fence closure drive device Fig. 5; Fig. 7 a detailed view of the building closure or fence closure drive device Fig. 6; Fig. 8 a perspective view of an exemplary embodiment of an antenna; Fig. 9 a top view of the antenna from Fig. 8; Fig. 10 a side view of the antenna from Fig. 8; Fig. 11 an embodiment of a remote control device; Fig. 12 another embodiment of a remote control device; Fig. 13 another embodiment of a remote control device; and Fig. 14 the underside of the remote control device Fig. 13.

[0037] The following will refer to the Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9 to Fig. 10. A building closure or fence closure drive device 20, hereinafter simply referred to as drive device 20, comprises a motor drive unit (not shown) and a receiver 22. The motor drive unit and the receiver 22 are generally arranged in a housing 24. The drive device 20 can, in particular, be a door drive device or a gate drive device.

[0038] The drive device 20 may also include a lighting device 26 and a display control device 28. The lighting device 26 is controlled depending on user input and / or environmental conditions.

[0039] The display control unit 28 has a display 30 for indicating an operating status of the drive device 20 and several control buttons 32 for operating, programming and controlling the drive device 20.

[0040] The receiving device 22 is designed to receive radio signals from a remote control device (which will be described later). The receiving device 22 has, for example, an antenna 36 formed from a sheet metal element 34.

[0041] The receiving device 22 can be part of a transceiver 38. The transceiver 38 is designed for bidirectional communication between the transceiver 38 and a remote control device. A current state of the building closure or fence closure drive device 20 can thus be transmitted to a remote control device, allowing a user to check the current operating status.

[0042] In this embodiment, the antenna 36 is shaped like a bow. Any other common type of magnetic antenna, such as circular, square, and the like, is equally possible.

[0043] The antenna 36 preferably comprises a first connection area 40 and a second connection area 42. The first connection area 40 and the second connection area 42 are electrically connected to each other by means of a connecting area 44.

[0044] The first connection area 40 can, for example, be used to tap and / or feed in a radio signal, whereas the second connection area 42 can be a ground connection 46.

[0045] The antenna 36 is preferably formed from a sheet metal part. For example, the sheet metal element 34 is punched out of the sheet metal. The antenna 36 can be provided with a coating 48. The coating 48 can, for example, comprise a layer of lacquer 50. The lacquer is preferably electrically insulating.

[0046] The coating 48 can alternatively or additionally be made of a metal, such as tin. This provides sufficient corrosion protection for the antenna 36.

[0047] The antenna 36 is preferably arranged on a circuit board 52, on which the receiving device 22 may also be provided. The antenna 36 can be attached to the circuit board 52, for example, by soldering or clipping.

[0048] The antenna 36 can also be configured to transmit and / or receive radio signals with different carrier frequencies. For this purpose, a third connection area 54 is preferably provided. The first connection area 40 is arranged between the second connection area 42 and the first connection area 54.

[0049] The third connection area 54 is provided in particular with different distances to the first connection area 40 and the second connection area 42 and is electrically conductively connected to the connection area 44.

[0050] The third connection area 54 includes a frequency-determining component that significantly determines the matching of the antenna 36 to a carrier frequency. The frequency-determining component can, for example, be a capacitor with a fixed or adjustable capacitance.

[0051] The first connection area 40 and the second connection area 42 define a first recess 56 and a first section 57 of the connection area 44. The first connection area 40 and the third connection area 54 define a second recess 58 and a second section 59 of the connection area 44. The second section 59 is typically 4 to 15 times the length of the first section 57.

[0052] The first recess 56 and the second recess 58 are each filled with a dielectric 60. In this example, the dielectric 60 is formed by air.

[0053] The antenna 36 preferably has a chamfer 62 at the transition areas between the first connection area 40 and the connection area 44, as well as between the second connection area 42 and the connection area 44. The chamfer 62 preferably runs at an angle of 45° to the two connection areas 40, 42 and / or to the connection area 44.

[0054] The second and third connection areas 42, 54 preferably have a length L between 7.0 mm and 17.0 mm and a width B between 1.0 mm and 5.0 mm. The first connection area 40 preferably has a length L1 between 8.0 mm and 17.0 mm and a width B1 between 1.0 mm and 2.5 mm. The sheet metal element 34 forming the antenna 36 preferably has a thickness D between 0.5 mm and 1.0 mm and an overall length L A between 21.0 mm and 35.0 mm and an overall width B A between 13.0 mm and 17.0 mm.

[0055] Examples of remote control devices are described below with reference to the Fig. 11, Fig. 12, Fig. 13 to Fig. 14 explained. The antenna 36 described above can also be used with remote control devices. The antennas described below can also be used with the receiving device 22 or the transceiver 38.

[0056] The drive device 20 can include a mobile remote control unit 64. The mobile remote control unit 64 has a transmitter 66 for transmitting radio signals. The second transmitter 66 includes a second antenna 68. The second antenna 68 is preferably formed from a conductor track section 70.

[0057] As in Fig. As shown in Figure 11, the second antenna 68 is arranged on a second circuit board 72. The second circuit board 72 has a first side 74 and a second side 76. The first side 74 and the second side 76 are populated with components 78.

[0058] The second antenna 68 is preferably arranged on the first side 74. In particular, the second antenna 68 is arranged at a corner of the second circuit board 72. The second antenna 68 is almost square and has chamfered corners 80. The second antenna 68 comprises a first connection area 82, a second connection area 84, and a connecting area 86 that electrically connects the first connection area 82 and the second connection area 84.

[0059] The connection areas 82 and 84 each have the same function as the connection areas 40 and 42. The connection areas 80 and 82 and the connecting area 84 define a circuit board area 88, which acts as a dielectric 90. The dielectric 90 is therefore formed from the circuit board material. The circuit board material is particularly suitable for high-frequency applications. Examples of suitable materials are RO 4003, glass fiber, ceramic, Al₂O₃, or Teflon. Furthermore, the second antenna 68 is preferably provided with an electrically insulating lacquer layer 92.

[0060] Fig. Figure 12 shows a further embodiment of a mobile remote control device 94. The mobile remote control device 94 comprises a transmitter 96 and a second circuit board 98. The transmitter 96 can be part of a transceiver 100. The second circuit board 98 has a first side 102 and a second side 104. The first side 102 is populated with components 106. The second side 104 has no components except for connection components 108.

[0061] The transceiver 98 has a second antenna 110. The second antenna 110 is preferably arranged on the first side 102 and runs along a circumferential section 112 of the second circuit board 98. The second antenna 110 is also formed from a conductor track section 114. Preferably, the conductor track section 114 is provided with an electrically insulating varnish layer 116.

[0062] The second antenna 110 is essentially L-shaped. The second antenna 110 is further configured for transmitting and / or receiving different carrier frequencies. The second antenna 110 comprises a first connection section 118, a second connection section 120, a third connection section 122, and a connecting section 124.

[0063] The first and second connection areas 118, 120 define a first section 121. The first and third connection areas 118, 122 define a second section 123. The second section 123 has 2 to 4 times the length of the first section 121.

[0064] The first connection area 118 is used for injecting and / or tapping a radio signal. The second connection area 120 is a ground connection 126. The third connection area 122 comprises a frequency-determining component 128, which significantly determines the matching of the second antenna 110 to a carrier frequency. The frequency-determining component 128 can, for example, be a capacitor with a fixed or adjustable capacitance.

[0065] A circuit board area 130, located between the conductor track section 114 and the transceiver 100, forms a dielectric 132. The circuit board area 130 is provided with recesses 134. The dielectric 132 is therefore formed from a combination of air and circuit board material.

[0066] The following refers to the Fig. 13 and Fig. Reference is made to Figure 14. A remote control device 136 comprises a transmitter 138 and a second circuit board 140. The second circuit board 140 has a first side 142 and a second side 144. The first side 142 is populated with components 146, whereas the second side 144 has no components. The second side 144 instead has a ground area 148.

[0067] The transmitting device 138 is arranged on the first side 142, whereas a second antenna 152, formed from a conductor track section 150, is arranged on the second side 144. The second antenna 152 is electrically connected to the transmitting device 138 by means of so-called vias 154.

[0068] How in particular Fig. As can be seen from Figure 13, the second antenna 152 runs essentially along almost the entire circumference of the second circuit board 140. The second antenna 152 surrounds the ground area 148 except for a recess 156.

[0069] The second antenna 152 comprises a first connection area 158 and a second connection area 160. The first connection area 158 is used for feeding in and / or tapping a radio signal; the second connection area 160 serves as a ground connection 162. The connection areas 158 and 160 are electrically connected by a connecting area 164.

[0070] The second antenna 152 can, for example, be provided with a metal coating 166. The metal coating 166 can in turn be coated with an electrically insulating lacquer layer 168.

[0071] The receiving and transmitting devices described herein include so-called magnetic or loop antennas. Loop antennas, such as those described above, do have a directional characteristic. However, in the predominant installation situations in the fields of door and gate technology and home automation, the antenna's positioning is not primarily determined by its directional properties. Rather, the aim is to achieve good results in as many installation situations as possible. Especially with handheld transmitters, the antenna's positioning is not truly predictable. Therefore, the antenna's directional characteristic plays only a minor role in the embodiments presented here.

[0072] The loop antenna can be formed by a conductive trace (copper, gold-plated copper, etc.) or by a U-shaped sheet metal element. Compared to circuit board material, air is preferred as a dielectric. However, antennas with air as the dielectric generally require more space, so depending on the application, this minor disadvantage can be accepted to make the transmitting and receiving equipment more compact. For further improvement, the circuit board material can be milled out to increase the proportion of air in the dielectric.

[0073] Compared to a wire antenna, a loop antenna has, among other things, the following advantages: • The loop antenna can be automatically assembled like a conventional component. • There is a lower risk of assembly errors during final assembly. • No subsequent alignment and / or adjustment is required. • The antenna material is inexpensive, stamped sheet metal. • The dielectric contains mostly air instead of circuit board material FR4, which reduces the loss factor (tangent of the loss angle). • By accepting a slightly higher loss factor, the antenna and the associated transmitting or receiving equipment can be further reduced in size. • To adapt to different carrier frequencies, it is sufficient to change one component, for example a frequency-determining capacitor.
