Description

Technical Field

[0001] The present invention relates to an apparatus including an antenna according to claim 1. Summary of the Invention

[0002] The purpose of this invention is to provide a device in which at least the antenna, more preferably the entire sensor, can be easily disassembled / assembled and can be configured to a certain angular orientation.

[0003] This objective is achieved by the features of claim 1.

[0004] Advantageous embodiments of the invention are described in the dependent claims.

[0005] The device according to the invention includes a mounting bracket for connection to an external component. The external component may be a wall, a post next to a barrier gate, or a housing for operating a connecting lifting rod, etc.

[0006] The device includes an antenna housing to house the antenna, particularly a radar antenna. In addition to the antenna, the housing can also house the entire door sensor for controlling automatic doors or automatic barriers.

[0007] According to the present invention, the antenna housing is detachably connected to the mounting bracket, allowing it to rotate relative to the mounting bracket to achieve orientation of the antenna relative to the mounting bracket and external components connected to the mounting bracket.

[0008] According to the present invention, both the mounting bracket and the antenna housing include upper and lower guide structures that are arc-shaped around a central axis, thus forming part of a circumference.

[0009] The upper and lower guide structures are spaced apart from each other along the axial direction on the mounting bracket. The upper and lower guide structures of the mounting bracket are arranged coaxially with respect to their corresponding central axes. According to this arrangement, the central axes of the upper and lower guide structures define a common central axis, thereby defining the rotation axis of the mounting bracket.

[0010] Furthermore, the upper and lower guide structures of the antenna housing are arranged coaxially with respect to their corresponding central axes.

[0011] In the assembled state, the antenna housing is connected to the mounting bracket, and the upper guide structure of the antenna housing is interconnected with the upper guide structure of the mounting bracket, causing them to overlap in the axial and circumferential directions, thus forming a corresponding upper arc-shaped bearing. The upper guide structure of the antenna housing is guided by the upper guide structure of the mounting bracket, allowing the antenna housing to rotate around the rotation axis of the mounting bracket.

[0012] In the assembled state, the lower guide structure of the antenna housing is connected to the lower guide structure of the mounting bracket, causing them to partially overlap in the axial and circumferential directions, thus forming a corresponding lower arc-shaped bearing. The lower guide structure of the antenna housing is guided by the lower guide structure of the mounting bracket, allowing the antenna housing to rotate around the rotation axis of the mounting bracket.

[0013] Each guide structure, namely the lower guide structure of the antenna housing, the lower guide structure of the mounting bracket, the upper guide structure of the antenna housing, and the upper guide structure of the mounting bracket, is arranged to allow the antenna housing to be inserted into and separated from the mounting bracket, and once inserted, the antenna housing can be rotated relative to the mounting bracket about a rotation axis in a simple manner.

[0014] This can be achieved when the upper guide structure overlaps axially to a certain extent, causing the lower guide structure to enter an interlocking state. In the assembled state, as the antenna housing moves downwards, this axial overlap of the upper guide structure decreases, thereby increasing the axial overlap of the lower guide structure.

[0015] According to another embodiment, at least one upper guide structure and at least one lower guide structure extend at an angle of less than 180°, especially the lower guide structure extends at an angle of less than 90°.

[0016] By limiting the extension of the lower guide structure to a small angle, particularly less than 90°, and by using a significantly larger radius for the lower arc-shaped guide structure than for the upper arc-shaped guide structure, the mounting bracket can have a very shallow depth. Due to this bearing in the antenna housing, the mounting bracket can be constructed in a very compact manner.

[0017] The radius of the lower arc-shaped guide structure depends on the dimensions of the antenna housing. Preferably, the antenna housing may include a flange to partially increase the radial range of the antenna housing, thereby providing a larger lower bearing radius.

[0018] Furthermore, due to the use of different upper and lower bearing radii, there is a space between the lower end of the antenna housing and the mounting bracket. This space can be advantageously used for purposes other than supporting the antenna housing, such as for connecting electrical connectors.

[0019] According to another advantageous embodiment, the radius of the upper arc-shaped guide structure is smaller than the radius of the lower arc-shaped guide structure. This allows for a smaller distance between the upper end and the rear wall of the mounting plate, which serves as the mounting bracket. This has a positive impact on the forward orientation of the mounting portion.

[0020] Specifically, the upper and lower guide structures of the antenna housing can extend axially in opposite directions. The same applies to the upper and lower guide structures of the mounting bracket.

[0021] In another advantageous embodiment, the lower guide structure of the antenna housing includes an inner surface having an inner radius relative to the central axis, and the lower guide structure of the mounting bracket includes an outer surface having an outer radius. In the assembled state, the inner surface is in close contact with the outer surface. The inner radius is smaller than the outer radius, preferably less than 20%, more preferably less than 10%. According to the most preferred embodiment, the outer radius is less than 5% smaller than the inner radius or even equal to the inner radius.

[0022] In another advantageous embodiment, the upper guide structure of the antenna housing includes an outer surface having an outer radius relative to the central axis, and the upper guide structure of the mounting bracket includes an inner surface having an inner radius. In the assembled state, the inner surface is close to the outer surface. The inner radius is smaller than the outer radius, preferably less than 20%, more preferably less than 10%. According to the most preferred embodiment, the inner radius is less than 5% smaller than the outer radius. According to another embodiment, the inner radius is even equal to or almost equal to the outer radius.

[0023] Preferably, the upper and lower guide structures of the mounting bracket and the upper and lower guide structures of the antenna housing are arranged around the rotation axis in opposite sectors. This allows the antenna housing to be inserted into the mounting bracket by tilting. Furthermore, this also allows for flexible application of different sectors.

[0024] In a highly preferred embodiment, the mounting bracket and / or antenna housing includes a spring element that applies a preload in the axial direction between the antenna housing and the mounting bracket; this spring element is hereinafter referred to as the axial spring element. Due to the preload, the antenna housing compresses the mounting bracket, reducing the gap between the mounting bracket and the antenna housing in the lower bearing.

[0025] According to another improved embodiment of the invention, the mounting bracket and / or antenna housing includes a spring element that applies a preload force between the antenna housing and the mounting bracket in a radial direction perpendicular to the axis of rotation of the antenna housing. This spring element is hereinafter referred to as a radial spring element. Therefore, the spring force is preferably guided radially along the upper and lower guide structures of the mounting bracket, thus acting perpendicular to the axis of rotation on the antenna housing. Due to this spring effect, the radial clearance is reduced because the upper and lower guide structures of the antenna housing compress the corresponding upper and lower guide structures of the mounting bracket. Due to the preload force between the mounting bracket and the antenna housing, the antenna housing is securely locked, thus preventing wobbling.

[0026] In order to attach the antenna housing to the mounting bracket, the antenna housing is inserted into the mounting bracket against the preload force of the radial spring element.

[0027] The radial spring element can be a flexible component of the mounting bracket, particularly a bent finger that acts as a spring finger. Preferably, the radial spring element acts on the portion of the antenna housing to which axial force is applied. This increases friction on the corresponding guide structure, particularly the upper bearing, thereby facilitating the installation process by temporarily fixing the insertion position.

[0028] According to another embodiment, the mounting bracket and antenna housing include axially interacting support structures that form several angular displacement support positions due to a positive locking mechanism between the support structures.

[0029] The angular azimuth of the antenna housing relative to the mounting bracket can be changed by removing the antenna housing from the interacting support structure. Preferably, this direction of movement is opposite to the preload of the axial spring element, particularly in the axial direction. Therefore, the angular azimuth is fixed not only by gravity but also by the preload, thus reliably preventing further rotation under the preload.

[0030] According to the present invention, the designations of "upper" and "lower" are not necessarily related to the direction of gravity. However, in the preferred installation position, the axial spring element acts in the direction of gravity.

[0031] According to another embodiment, the support structure includes a pin on a mounting bracket and a plurality of angled compartments on the antenna housing. The pin on the mounting bracket can be inserted axially into a compartment of the antenna housing such that once the pin is in the compartment, the antenna housing interlocks with the mounting bracket circumferentially. Because multiple compartments are distributed circumferentially, multiple different angular positions can be determined. Therefore, the antenna housing can easily orient its angular position relative to the mounting bracket. Specifically, the compartments allow angular positions of -20°, -10°, 0°, +10°, and +20°.

[0032] According to another embodiment, the device includes a cover frame detachably connected to a mounting bracket. In the assembled state, the cover frame prevents relative movement between the antenna housing and the mounting bracket along the axial insertion direction of the pin, preferably opposite to the axial preload. By connecting the cover frame to the mounting bracket, the antenna housing can no longer rotate due to the positive locking mechanism of the cover frame preventing necessary axial movement.

[0033] According to another embodiment, the antenna housing includes an electrical connector located on the opposite side of the guide structure on the antenna housing.

[0034] Another aspect of the invention relates to a boom gate, also known as a boom barrier, to which the device of the invention is connected. The device includes a radar sensor enclosed within an antenna housing for controlling the boom. According to the invention, the antenna housing can be easily installed or replaced in a mounting bracket, which may already be partially connected to the boom. Depending on the desired application, the antenna housing can be easily oriented to its angular position relative to the mounting bracket and / or the boom. Attached Figure Description

Detailed Implementation

[0036] Figure 1 and Figure 2 The two parts of the device 10 according to the invention are shown in the separated state. Figure 1 The mounting bracket 12 of the device 10 according to the present invention includes an upper guide structure 14. Specifically, the upper guide structure 14 is a nearly semi-circular wall centered on the central axis CA12, with an inner radius of R12_1. The upper guide structure 14 and the lower guide structure 16 are spaced apart by an axial distance. The lower guide structure 16 is specifically a short arc-shaped wall centered on the central axis CA12 of the mounting bracket 12, with an outer radius of R12_2.

[0037] The lower guide structure 16 is built into the groove of the mounting bracket 12. For example... Figure 2 As shown, the flange 45 of the antenna housing 30 can partially pass through the mounting bracket 12. (As indicated...) Figure 1 As shown, both the upper guide structure 14 and the lower guide structure 16 include a common central axis CA12.

[0038] Therefore, the central axis CA12 of the guide structures 14 and 16 also defines the rotation axis RA around which the antenna housing 30 can rotate.

[0039] Mounting bracket 12 includes at least one radially acting spring element, which in this embodiment is specifically a spring finger 20. The spring finger 20 is integrally formed with the rear wall of mounting bracket 12 and is bent to apply a spring force substantially perpendicular to the rear wall. This spring force will hereafter be referred to as the positive force FF.

[0040] Furthermore, a spring element 80 acting axially relative to the mounting bracket 12 is positioned close to the upper guide structure 14. The axially acting spring element 80 applies an axial force to the antenna housing. This axial force is subsequently referred to as the downward pressure.

[0041] Figure 2 A perspective view of the antenna housing 30 is shown. The antenna housing 30 includes two parts: a front cover 34 and a rear cover 36. The antenna housing 30 accommodates the antenna 32 (in...). Figure 4 (Illustrative illustration). The purpose of this invention is to provide a detachable technical solution that facilitates the angular orientation of the antenna housing 30 relative to the mounting bracket 12, thereby allowing for flexible orientation of the housed antenna 32 and its radiation direction.

[0042] The antenna housing 30 includes an upper guide structure 40, which includes an arcuate front wall 42 and an arcuate rear wall 44, wherein the rear wall 44 of the upper guide structure 40 is specifically the periphery of a pin-like structure. The arcuate rear wall 44 includes an outer wall with an outer radius of R30_1. This outer radius R30_1 is slightly larger than the inner radius R12_1 of the upper guide structure 14 of the mounting bracket 12, and specifically less than 5% larger than the inner radius R12_1. The upper bearing radius can be defined as the inner radius R12_1. A groove is formed between the arcuate rear wall 44 and the arcuate front wall 42, which extends around the same common central axis CA30 as the rear wall 44. The size of the groove corresponds to the upper guide structure 14 of the mounting bracket 12.

[0043] In the illustrated embodiment, the upper guide structure 14 of the mounting bracket 12 is specifically an arcuate wall, guiding between the arcuate front wall 42 and the arcuate rear wall 44. The corresponding central axes of the arcuate front wall 42, the arcuate rear wall 44, and the lower guide structure 46 are arranged coaxially with each other relative to the central axis CA30, which thereby defines the rotation axis RA of the antenna housing 30. The upper bearing radius is relatively small, allowing sufficient free space for the axially acting spring element 80 between the upper guide structure 14 and the rear wall of the mounting bracket 12. Therefore, sufficient space is provided even when the antenna housing 30 is positioned at its maximum rotational position of +20° or -20°.

[0044] Figure 3 It is along Figure 2 The image shown is a bottom perspective view of the antenna housing 30 as observed by DV in the direction of view. In this view, the lower guide structure 46 of the flange 45 of the antenna housing 30 can be seen. This lower guide structure 46 includes a rear wall 50 with an inner radius of R30_2 and a front wall 48. (As shown...) Figure 1As shown, the outer radius R12_2 of the lower guide structure 16 of the mounting bracket 12 is slightly larger than the inner radius R30_2 of the rear wall 50. Specifically, the outer radius R12_2 is less than 5% larger than the inner radius R30_2. The lower guide structure 16 of the mounting bracket 12 is guided in a groove formed between the rear wall 50 and the front wall 48. The corresponding central axes of the arcuate front wall 48 and the arcuate rear wall 50 are coaxially aligned with each other. Because these central axes are coaxial with the central axes of the arcuate front wall 42 and the arcuate rear wall 44 of the upper guide structure 40, these central axes are located at the center of the antenna housing 30 and define the rotation axis RA of the antenna housing 30.

[0045] The front wall 48 includes recesses 62a-62e, which form a compartment into which a pin 18 can be inserted, such as Figure 6 As shown, the pin 18 is located on the lower guide structure 16 of the mounting bracket 12. Each compartment 62a, ..., 62e corresponds to a different angular position of the antenna housing 30 relative to the mounting bracket 12.

[0046] Figure 4 A cross-sectional view of the assembled device 10 according to the present invention is shown. The device 10 includes a mounting bracket 12 and an antenna housing 30. The antenna housing 30 is an assembly of a front cover 34 and a rear cover 36, with a gasket 38 disposed between the front cover 34 and the rear cover 36 to increase the waterproof performance of the antenna housing 30.

[0047] To achieve the assembled state, the antenna housing 30 is inserted into the mounting bracket 12 at an angle, pressing the upper spring finger 20 and the axially acting spring element 80.

[0048] In this embodiment, the upper guide structure 14 of the mounting bracket 12 is specifically a semi-circular wall, which is inserted into the upper guide structure 40 of the antenna housing 30. The upper guide structure 40 of the antenna housing 30 provides an arcuate groove defined by an arcuate front wall 42 and an arcuate rear wall 44. The upper guide structure 14 of the mounting bracket 12 and the upper guide structure 40 of the antenna housing 30 form an arcuate upper bearing.

[0049] The lower guide structure 16 is housed within a recess in the mounting bracket 12, while the lower guide structure 46 of the antenna housing 30 provides a recess formed between the rear wall 50 and the front wall 48 of the lower guide structure 46. The lower guide structure 16 of the mounting bracket 12 is guided within the recess between the rear wall 50 and the front wall 48. The lower guide structure 46 of the antenna housing 30 is specifically a flange 45 extending beyond the main body of the antenna housing 30. During assembly of the device 10, the flange 45 extends into or partially through the mounting bracket 12.

[0050] The spring finger 20, integral with the rear wall of the mounting bracket 12, applies a spring force perpendicular to the rear wall, i.e., a positive force FF acting on the antenna housing 30. Due to the positive force FF applied by the spring finger 20, the rear wall 50 of the lower guide structure 46 of the antenna housing 30 presses against the lower guide structure 16 of the mounting bracket 12. Due to the positive force FF, the rear wall 44 of the upper guide structure 46 of the antenna housing 30 presses against the upper guide structure 14 of the mounting bracket 12. This reduces the radial clearance between the upper and lower arc bearings.

[0051] Since the rear wall 44 of the upper guide structure 40 and the rear wall 50 of the lower guide structure 46 are both part of the rear cover 36, the positive force FF acts only on the rear cover 36. According to this configuration, the front cover 34 is not subjected to the positive force FF, therefore there is no stress at the interface between the front cover 34 and the rear cover 36, which is sealed by the gasket 38.

[0052] Furthermore, the mounting bracket 12 includes an axially acting spring element 80 that applies a spring force parallel to the rotation axis RA to the antenna housing 30. This spring force is referred to as the downforce DF, and it preloads the antenna housing 30 onto the lower guide structure 16 of the mounting bracket 12.

[0053] As described above, the front wall 48 includes recesses 62a-62e into which a pin 18 can be inserted. Due to the downward pressure DF, the pin 18 and the recesses 62a-62e are pressed against each other. Therefore, due to the preload of the axially acting spring element 80, the angular position of the antenna housing 30 is fixed relative to the mounting bracket 12.

[0054] Therefore, the change of position can only occur by moving the antenna housing 30 axially against the axially acting spring element 80 before rotating the antenna housing 30 to a new angular position, that is, moving another groove to the latch 18.

[0055] According to the present invention, the antenna housing 30 can be easily inserted into the mounting bracket 12, can be rotated, and can be reliably fixed at a certain angle relative to the mounting bracket 12.

[0056] Figure 5 Show Figure 4 A cross-sectional view VV shows the upper guide structures 14 and 40 passing through a 10° rotation angle. Due to the positive force FF, the rear wall 44 of the antenna housing 30 compresses the guide structure 14. From Figure 4It can be seen that the rear wall 44 is part of the rear cover 36 of the antenna housing 30. The front wall 42 is part of the front cover 34, wherein the front wall 42 is not subject to preload but improves the guiding effect during the rotation of the antenna housing 30. To precisely define the rotation axis RA, the inner radius R12_1 of the upper guide structure 14 of the mounting bracket 12 is slightly larger than the outer radius R30_1 of the rear wall 44. The bearing radius of the upper bearing is determined by the inner radius R12_1 of the upper guide structure 14 of the mounting bracket 12.

[0057] Figure 6 Show Figure 4 Cross-sectional views VI-VI show the lower guide structures 16 and 46 passing through the center. In this view, the angle is set to 0° when the pin 18 is inserted into the centrally located compartment 62c. This view shows that the rear wall 50 presses against the lower guide structure 16 of the mounting bracket 12 due to the positive force FF. The inner radius R30_2 of the rear wall 50 is slightly smaller than the outer radius R12_2 of the lower guide structure 16. Slightly smaller means R12_2 / R30_2 > 0.95. In this embodiment, the lower bearing radius is determined by the outer radius R12_2.

[0058] These two structures provide basic guidance. However, there is also the front wall 48, which allows for a slight clearance in the lower bearing. The rear wall 50 is also part of the rear cover 36. Therefore, the axial and radial preload of the device 10 in the assembled state acts only between the rear cover 36 and the mounting bracket 12. This makes the front cover 34 immune to external forces.

[0059] Figure 7 This diagram shows the circumferential distribution of the upper guide structure 14 and lower guide structure 16 of the mounting bracket 12, and the upper guide structure 40 and lower guide structure 46 of the antenna housing 3015. According to this embodiment, the upper guide structures 14, 40 and the lower guide structures 16, 46 are respectively oriented towards two opposite axial ends of the device 10. The upper guide structures 14, 40 have a smaller bearing radius and face forward, away from external components that the device 10 may connect to, while the lower guide structures 16, 46 have a larger radius and face backward, i.e., towards external components that the device 10 may connect to.

[0060] The upper guide structures 14 and 40 extend at an angle of almost 180°, while the lower guide structures 16 and 46 extend at an angle of only 30°. The arc-shaped guide structure 40, especially the rear wall 44, can extend at an angle of more than 180° to reduce the gap between it and the upper guide structure 14, which extends at an angle of less than or equal to 180°, especially at the maximum angle position.

[0061] Figure 8 for Figure 7 A cross-sectional functional diagram, basically showing the relationship with Figure 2Similarly, the device 10 also includes a cover 70 connected to the mounting bracket 12. This cover 70 extends between the upper part of the mounting bracket 12 and the antenna housing 30, thereby preventing axial movement of the antenna housing 30. Therefore, once the cover 70 is connected to the mounting bracket 12, the angular position of the antenna housing 30 relative to the mounting bracket 12 cannot be changed. The cover 70 also protects the antenna housing 30 from rain.

[0062] Figure 9 An automatic lifting boom 100, also known as a barrier gate, is shown. The lifting boom 100 includes a boom 120 rotatably connected to a housing 110 containing a lifting actuator. A device 10 according to the invention is connected to the housing 110 containing the lifting actuator.

[0063] Preferably, the device 10 according to the invention includes a sensor for providing an input signal for controlling the lifting rod 100.
