Description

[0001] The invention relates to a fixing system for a modular antenna according to the preamble of claim 1, a method for assembling a fixing system for a modular antenna according to the preamble of claim 7, a modular antenna according to the preamble of claim 13 and a vehicle according to the preamble of claim 15.

[0002] Various antenna devices are known from the prior art. For example, WO 2010 / 109459 A1 shows a rotating antenna.

[0003] WO 2006 / 136221 A1 discloses a top antenna having a worm gear, by means of which the antenna can be fixed.

[0004] DE 200 18 834 U1 describes a combination of a roof antenna and a signal light for a vehicle.

[0005] A cross-shaped rotating device for locking a top antenna is also known from DE 10 2012 207 438 A1.

[0006] DE 10 2005 044 618 A1 shows a clamping element with which a roof antenna of a vehicle can be fastened.

[0007] Finally, DE 600 20 769 T2 discloses an antenna which can be adjusted by means of an electric motor.

[0008] In the field of roof antennas for vehicles, it is generally known to position the radio unit on the outside of the support structure, while the control unit should be arranged inside or behind the support structure in order to protect it from external influences. Therefore, for this purpose, the support structure must be assembled from both sides. This is accompanied by increased operating complexity, because the mechanical and electrical components of the radio unit and the control unit must be coupled through the support structure.

[0009] The object of the present invention is to find a technical solution with which an antenna can be fastened to a supporting structure from both sides, wherein the assembly effort should be as low as possible.

[0010] This object is achieved by the technical solutions of independent claims 1, 7, 13 and 15. Further preferred embodiments of the invention result from the remaining features mentioned in the dependent claims.

[0011] A first aspect of the present invention relates to a fixing system for a modular antenna, comprising:

[0012] - a load-bearing structure having through holes; and

[0013] - A modular antenna comprising:

[0014] - an upper module having a radio unit with a control plug;

[0015] a lower module having a control unit with a complementary control plug;

[0016] The upper module can be placed against the support structure above the through-opening and the lower module can be placed against the support structure below the through-opening, wherein a control plug and a complementary control plug can be engaged through the through-opening.

[0017] According to the present invention, the upper module also includes an external thread arranged concentrically with the control plug, and the lower module includes a nut arranged concentrically with a complementary control plug and having an external toothing, and a planetary pinion is supported in the lower module, the planetary pinion meshes with the external toothing of the nut, and the planetary pinion can clamp or clamp the upper module and the lower module on the supporting structure via the nut and the external thread.

[0018] The fixing system of the invention enables particularly simple assembly, since the combination of nut and external thread for clamping is arranged concentrically with the control plug. Since the nut must be positioned relative to the external thread on the one hand and the control plug must be positioned relative to the complementary control plug on the other hand, the spatially concentrated arrangement of the components significantly simplifies assembly and makes it easier to compensate for tolerances. This is particularly applicable in the case where the plug connector includes a plurality of plug contacts and the complementary plug connector includes a plurality of complementary plug contacts, which must contact each other, for example must be inserted into each other. A concentric arrangement of the nut and the control plug can be achieved, since the planetary pinion is arranged on the outer periphery of the nut or arranged next to the nut and meshes with the nut and does not take up structural space in the center of the arrangement. As a result, the planetary pinion can also be particularly well accessible for actuation.

[0019] The term "concentric" also includes the case where the external thread extends at least partially around the control plug. Correspondingly, for the nut, the term includes the case where the nut extends at least partially around the complementary control plug. The external thread can be arranged on the outer surface of the control plug or also on other parts of the upper module.

[0020] The load-bearing structure may, for example, comprise a plate having holes.The load-bearing structure preferably comprises a vehicle roof.

[0021] The modular antenna preferably comprises a top antenna (or a roof antenna).

[0022] The control plug and the complementary control plug are preferably adapted to each other so that the antenna and the control unit can be coupled in terms of data and / or energy technology. In addition, the term "plug" should be understood in a broad sense in terms of structure. It is important that a preferably detachable contact can be established by performing a feed movement.

[0023] In a preferred design of the fixing system of the present invention, it is provided that the upper module includes a clip-on connector and the lower module includes a complementary clip-on connector, by means of which the lower module and the upper module can be preassembled to each other, wherein a nut can be placed against a flange of the external thread.

[0024] The clip connector and the complementary clip connector are preferably adapted to each other in such a way that the lower module can be clipped onto the upper module from below and the lower module is oriented parallel or horizontally relative to the upper module. For this purpose, the clip connectors that are clipped together can preferably absorb tilting moments. In addition, the clip connectors that are clipped together can preferably absorb torques when the nuts are tightened. Accordingly, preferably at least two clip connectors and complementary clip connectors are provided in each case. The clip connector is preferably arranged concentrically with the control plug on the upper module, and the complementary clip connector is arranged concentrically with the complementary control plug on the lower module.

[0025] In other words, “concentrically” in this context includes that the clip connector and the complementary clip connector are arranged radially spaced apart from the control plug or the complementary control plug and are distributed around the control plug or the complementary control plug, for example, in the circumferential direction.

[0026] All this significantly simplifies screwing the nut onto the external thread via the planetary pinion. On the one hand, the nut finds the flange on the external thread more easily, since the clamping connection makes it easier to position the lower module. On the other hand, the lower module is securely hung below the upper module via the clamping connection and does not have to be fixed separately while the nut is being clamped.

[0027] Preferably, the lower module comprises a housing. The housing may preferably comprise an upper part and a lower part. Thus, the remaining parts of the lower module can be preassembled simply.

[0028] Preferably, the planetary pinion comprises a tool attachment, which can be accessed from the outside, preferably from below, on the housing.After the lower module is clamped to the upper module for preassembly, the main assembly can be simply performed from the outside by tightening the nut through the tool attachment.

[0029] In a further preferred embodiment of the fastening system according to the invention, it is provided that the nut can be displaced in the longitudinal direction of the complementary control plug by means of a resilient bearing.

[0030] This significantly simplifies the pairing of the nut and the flange of the external thread, since, due to the flexibility in the spring support, smaller tolerances in the coaxial orientation of the nut and the external thread are quickly compensated.

[0031] In a further preferred embodiment of the fastening system according to the invention, it is provided that the tooth length of the planetary pinion is greater than the adjustment travel of the nut in the longitudinal direction.

[0032] This ensures that, regardless of how the nut is displaced in the longitudinal direction, the nut and the planetary pinion always mesh reliably.

[0033] In a further preferred embodiment of the fastening system according to the invention, it is provided that the nut bears sectionally against the inner wall of the lower module under the prestressing of the elastic bearing when the nut does not bear against the outer thread of the upper module.

[0034] For preassembly, the nut is therefore always in a defined home position.

[0035] In a further preferred embodiment of the fastening system according to the invention, it is provided that when the nut comes into contact with the collar of the external thread, the nut is moved away from the inner wall under further prestressing of the elastic bearing.

[0036] This provides tactile feedback during assembly and makes it easier for the nut to find the flange of the external thread. In addition, in the case of the above-mentioned pre-assembly of the lower module on the upper module, a preload is generated by the clip connection so that the lower module is hung on the upper module with low vibration.

[0037] Another aspect of the invention relates to a method for assembling a fixing system for a modular antenna, comprising the steps of:

[0038] a) providing a supporting structure with a through hole and a modular antenna, the modular antenna comprising:

[0039] - an upper module having a radio unit with a control plug;

[0040] a lower module having a control unit with a complementary control plug;

[0041] b) Placing the upper module over the through-opening, wherein the upper module rests on the supporting structure and the lower module is placed under the through-opening, wherein a control plug and a complementary control plug engage through the through-opening.

[0042] According to the present invention, the method further comprises the following steps:

[0043] c) driving a planetary pinion which is supported in the lower module and meshes with an external toothing of a nut, wherein the nut is arranged concentrically with a complementary control plug in the lower module so that the nut is screwed onto an external thread which is arranged concentrically with the control plug in the upper module, thereby clamping the upper module and the lower module against the supporting structure.

[0044] By pressing the lower module onto the support structure, the lower module can be placed against the support structure before the planetary pinion is driven. However, the lower module can also be preassembled first as described further below.

[0045] In a preferred embodiment of the method according to the invention, it is provided that a fastening system according to the invention as described above is used.

[0046] In a more preferred embodiment of the method according to the invention, it is provided that in a further step b') which is carried out before step c), the lower module and the upper module are pre-assembled on one another by clamping at least one clip connector of the upper module with at least one complementary clip connector of the lower module, wherein the nut rests on a flange of the external thread.

[0047] In other words, the lower module can be plugged on from below in a simple manner and thus be held autonomously for further assembly.

[0048] In a more preferred design of the method of the present invention, it is provided that the nut can be moved along the longitudinal direction of the complementary control plug by means of an elastic support, and in step b'), the nut first rests sectionally against the inner wall of the lower module under the preload of the elastic support, and then when the nut rests against the flange of the external thread, the nut is moved away from the inner wall under further preload of the elastic support.

[0049] In a further preferred embodiment of the method according to the invention, it is provided that the nut bears against the collar of the external thread before the clip connector and the complementary clip connector are clipped together.

[0050] In this way, before the nut is tightened in step c) by the planetary pinion, a preload is applied to the nut against the external thread, which makes it easier for the nut to find the correct mounting position on the external thread. If this is done, the clip connector can be clamped together so that the nut can no longer lose its mounting on the external thread.

[0051] In a further preferred embodiment of the method according to the invention, provision is made for the assembly to be carried out by driving the planetary pinion after preassembly in step c), thereby bringing the lower module into contact with the support structure and clamping the lower module with the upper module against the support structure.

[0052] Another aspect of the present invention relates to a modular antenna, comprising:

[0053] - an upper module having a radio unit with a control plug;

[0054] a lower module having a control unit with a complementary control plug;

[0055] The upper module and the lower module can be brought into contact with one another, wherein a control plug and a complementary control plug can engage.

[0056] According to the present invention, the upper module also includes an external thread arranged concentrically with the control plug, and the lower module includes a nut arranged concentrically with the complementary control plug and having an external tooth portion, and a planetary pinion is supported in the lower module, the planetary pinion meshes with the external tooth portion of the nut, and the planetary pinion can clamp the upper module and the lower module against each other through the nut and the external thread.

[0057] In a further preferred embodiment of the modular antenna according to the invention, it is provided that the modular antenna for the fastening system according to the invention is designed as described above and / or is designed for use in the method according to the invention as described above.

[0058] The supporting structure can be arranged accordingly between the upper module and the lower module in a position in which the upper module and the lower module can be brought into contact with each other and clamped against each other.

[0059] A further aspect of the invention relates to a vehicle comprising a fastening system according to the invention as described above and / or a modular antenna according to the invention as described above.

[0060] In other words, to summarize again, the invention relates to a fastening concept for a roof antenna, wherein the plug connection between the roof antenna and the control unit is arranged in the center of the fastening concept and the mechanical connection components are arranged around the plug connection.

[0061] Unless otherwise indicated in individual cases, the various embodiments of the invention mentioned in this application can be advantageously combined with one another.

[0062] The present invention will be described in the following embodiments with reference to the accompanying drawings. In the accompanying drawings:

[0063] Figure 1 Shows a fixing system according to the invention for a modular antenna according to the invention;

[0064] Figure 2 The lower module of the fixing system according to the present invention is shown;

[0065] Figure 3 The lower module is shown in cross-section;

[0068] Figure 6 A further view shows a fastening system according to the invention with an open lower module; and

[0069] Figure 7 A vehicle according to the invention is shown.

[0070] Figure 1 The fastening system 10 according to the invention for a modular antenna 12 according to the invention is shown in an isometric view.

[0071] The fastening system 10 comprises a load-bearing structure 14. In the present case, the load-bearing structure 14 exemplarily comprises a vehicle 16 (see Figure 7 ) is shown in section at the top of the panel. Figure 1 The angle in FIG. 1 is from obliquely below, ie, from the interior of the vehicle 16 toward the top.

[0072] The support structure 14 includes a through hole 18 (see, for example, Figure 6 ), which is hidden in this view and is therefore only shown as a dot-dash line.

[0073] The fixing system 10 also comprises a modular antenna 12 according to the invention, which has an upper module 20 and a lower module 22. The upper module 20 has a radio unit 24. The lower module 22 comprises a control unit 26.

[0074] Figure 1 The fastening system 10 is shown in an assembled state.

[0075] Here, the upper module 20 rests on the support structure 14 above the through-opening 18, and the lower module 22 rests on the support structure 14 below the through-opening 18. Here, as will be explained further below, the upper module 20 and the lower module 22 are clamped against the support structure 14 and are in contact with each other in terms of energy and data (more on this later) via a control plug 40 on the upper module 20 and a complementary control plug 38 on the lower module 38 through the through-opening 18.

[0076] The following references Figure 2 , which are described separately in more detail Figure 1 The lower module 22 of the fixing system 10 is provided. For this purpose, the lower module 22 is removed from its Figure 1 The side that is covered in the figure is shown isometrically, ie, from obliquely above.

[0077] exist Figure 2 The control unit 26 arranged in the housing 28 of the lower module 22 can be better seen in FIG. The housing 28 comprises an upper part 30 and a lower part 32.

[0078] An opening 34 is provided in the upper part 32. Figure 1 As shown, the opening 34 is oriented approximately concentrically with the through-opening 18 in the assembled state. Figure 1 The lower module 22 in the embodiment of the present invention lies against the supporting structure 14 in the region of the opening 34 .

[0079] Reference again Figure 2 The control unit 26 comprises a circuit board 36 on which the complementary control plug 38 is applied. The complementary control plug 38 matches the control plug 40 of the radio unit 24 of the upper module 20 and is in the assembled state ( Figure 1 ) is engaged with the control plug.

[0080] The control plug 40 of the radio unit 24 is Figure 6 The hidden parts are indicated by dot-dash lines. Figure 6 From the corresponding Figure 1 The lower module 22 is shown in FIG. 1 , but wherein, for the purpose of illustrating components further inside, shielding components such as the circuit board 36 and the housing 28 as well as some other components that will be described later are hidden.

[0081] At this point, the Figure 6 Firstly, it will be described how the control plug 40 and the complementary control plug 38 engage through the through-opening 18 when the fastening system 10 is assembled.

[0082] Figure 3 The lower module 22 is shown separately in the unassembled state in the two sectional views AA and BB. The inner structure of the lower module 22 according to the section line B is shown in the sectional view BB, and the inner structure of the lower module according to the section line A is shown in the sectional view AA.

[0083] In the sectional view BB, the complementary control plug 38 mounted on the circuit board 36 is shown in the center.

[0084] A nut 42 is arranged around the complementary control plug 38 or concentrically therewith. The nut 42 is provided with an external toothing 44 and meshes with a planetary pinion 46 via the external toothing. The nut 42 and the planetary pinion 46 are supported in the lower module 22. The planetary pinion 46 is mounted in the upper part 30 and the lower part 32 of the housing 28. The planetary pinion 46 extends through the lower part 32 with a tool attachment 54, by which the planetary pinion can be driven from the outside (see also Figure 1 ).

[0085] As combined Figure 3 As can be clearly seen in the sectional view AA and the isometric view in FIG. , the nut 42 rests on the inner wall 50 of the housing 28 at a shoulder 48 of the housing 28 and is guided in the radial direction by a circumferential surface 52 of the housing 28 .

[0086] In this arrangement, a rotation of the planet pinion 46 leads via the external toothing 44 to a rotation of the nut 42 .

[0087] Now refer to it again Figure 6 , it can be seen that the upper module 20 is provided with an external thread 56, which is arranged concentrically with the control plug 40. Figure 1 Assembled as shown, the external thread 56 also engages with the nut 42 (at Figure 6 (not shown) are arranged concentrically.

[0088] For the relative arrangement of the nut 42, please refer to Figure 5 , wherein the nut 42 and the planetary pinion 46 are in contact with Figure 6 The corresponding views are shown.

[0089] The nut 42 can clamp the upper module 20 and the lower module 22 against the supporting structure 14 through the external thread 56 by operating the planetary pinion 46 to screw the nut onto the external thread 56 and to tighten the housing 28 of the lower module 22 (at Figure 5 and Figure 6 The upper module 22 (not shown) is pressed against the supporting structure 14 and, in the process, the upper module 22 is pulled from above against the supporting structure 14.

[0090] exist Figure 3 It can also be seen that the nut 42 can be moved by the elastic support member 58. The elastic support member 58 (also shown in Figure 5 and Figure 6 In this case, the control plug 38 includes a plurality of brush springs arranged between the circuit board 36 and the nut 42. The nut 42 can be moved along the longitudinal direction 60 of the complementary control plug 38 by means of the brush springs under the constant prestressing of the elastic bearing 58.

[0091] In order that the planet pinion 46 and the nut 42 are nevertheless always in meshing engagement, the tooth length 62 of the planet pinion 46 is selected to be greater than the adjustment travel 64 of the nut 42 in the longitudinal direction 60 .

[0092] exist Figure 3In the state shown in which the upper module 20 and the lower module 22 are not assembled to each other, the nut 42 rests against the inner wall 50 of the lower module 22 in sections below the shoulder 48 under the preload of the elastic bearing 58, and the nut 42 is accessible to the outer thread 56 of the upper module 20 through the opening 34 in the housing 28. However, in this unassembled state, the nut 42 and the outer thread 56 of the upper module 20 are not yet in contact.

[0093] If the lower module 20 is now mounted on the upper module 22 and for this purpose the control plug 40 and the complementary control plug 38 are positioned relative to each other and moved toward each other, the nut 42 first rests on the collar 66 of the external thread 56 through the opening 34 and is then screwed onto the external thread 56 by actuating the planetary pinion 46. This is done in Figure 5 Thus, the nut 42 is first moved away from the inner wall 50 of the housing 28 (see Figure 3 ) and again come into contact with the inner wall 50 when the lower module 20 and the upper module 22 are clamped against the supporting structure 14.

[0094] exist Figure 4 4 illustrates how the nut 42 presses the upper part 30 of the housing 28 from below against the support structure 14 and thus pulls the upper module 20 from above against the support structure 14 .

[0095] To make the assembly of the fixing system 10 easier, the upper module 20 includes a clip-on connector 68. The lower module 22 includes a complementary clip-on connector 70 that matches the clip-on connector. Figure 5 and Figure 6 The clip connector 68 can be seen well in FIG. Figure 1 2 shows how the clip connector 68 extends from the upper module 20 through the lower module 22 and engages with a complementary clip connector 70. The clip connector 68 and the complementary clip connector 70 are used to first clip the lower module 22 onto the upper module 20 from below and thus pre-assemble it.

[0096] The pre-assembly and final assembly are explained again in steps below according to the method according to the invention for assembling the fastening system 10 for a modular antenna 12:

[0097] First, in step a), a carrier structure 14 with a through-opening 18 is provided, and a modular antenna 12 is provided. In this case, the modular antenna 12 is still present as a separate lower module 22 and upper module 20 .

[0098] In a further step b), the upper module 20 is placed on the support structure 14 above the through-opening 18, wherein the upper module rests on the support structure 14. In this case, the control plug 40 extends through the through-opening 18. Furthermore, the lower module 22 is placed below the through-opening 18, wherein the control plug 40 and the complementary control plug 38 engage.

[0099] In a further step b'), the lower module 22 and the upper module 20 are preassembled to one another by clipping the clip connector 68 of the upper module 20 to the complementary clip connector 70 of the lower module 22. This can be done during the engagement of the control plug 40 and the complementary control plug 38 or also after the control plug and the complementary control plug have been at least partially engaged.

[0100] At the same time, the nut 42 is still under the preload formed by the elastic bearing 58 and rests in sections against the inner wall 50 of the lower module 22 .

[0101] During preassembly, the nut 42 comes into contact with the flange 66 of the external thread 56 at a specific (design-related) point in time. This point in time depends on the specific kinematics of the fastening system 10 and is between the point in time when the control plug 40 first contacts the complementary control plug 38 and the point in time when the clip connector 68 is clamped with the complementary clip connector 70.

[0102] As the lower module 22 approaches the upper module 20 further, the nut 42 , which now presses against the collar 66 , is displaced over its adjustment travel 64 in the longitudinal direction 60 of the complementary control plug 38 away from the inner wall 50 due to the increased prestressing of the elastic bearing 58 .

[0103] After the clip connector 68 and the complementary clip connector 70 have been clipped together, the lower module 22 is pre-positioned relative to the upper module 20 under the preload formed by the elastic bearing 58 and is held autonomously by the clip connectors 68, 70. The control plug 40 and the complementary control plug 38 are already fully engaged, so they can no longer slip out.

[0104] The assembly is then completed by driving the planetary pinion 46 in step c), thereby screwing the nut 42 onto the external thread 56 and clamping the upper module 20 and the lower module 22 against the support structure 14. The drive can be carried out via the tool attachment 54. Reaction forces and torques are taken up and compensated by the clamping connectors 68, 70.

[0105] Figure 7 A vehicle 16 according to the invention is shown. The load-bearing structure 14 comprises the roof of the vehicle 16.

[0106] The modular antenna 12 according to the invention is designed as a top antenna. The upper module 20 is visible from the outside, while the lower module 22 is indicated internally by a dot-dash line.
