Description

Technical Field

[0001] The invention relates to the technical field of communication auxiliary equipment, in particular to an antenna rotating and lodging mechanism for a cabin. Background Art

[0002] As a carrier environment for equipment and personnel, shelters have good mobility and environmental adaptability and are widely used in various emergency support and field operations, especially as a carrier of mobile electronic information systems. The antenna on the shelter is a key component in the information transmission link, which requires it to be able to flexibly receive or transmit information.

[0003] Most of the existing antenna retraction mechanisms only have the retraction function:

[0004] For example, the utility model with the authorization publication number CN206774658U discloses a manual antenna folding mechanism, including a fixed mount fixed on the roof, a rotating body arranged in the fixed mount and a locking device for limiting the rotation of the rotating body, an antenna pillar is fixed on the rotating body, a rotating shaft is arranged in the fixed mount, the rotating body is rotatably connected with the rotating shaft, and the top surface of the fixed mount also has a bayonet that cooperates with the antenna column, so that the antenna column is stuck in the bayonet when it is in a vertical direction. This utility model solution can only horizontally lay down the antenna or stand it up at 90 degrees, and cannot accurately position it between 0 degrees and 90 degrees, and does not have the function of horizontal rotation.

[0005] Another example is the utility model with the authorization publication number CN211295351U, which belongs to the technical field of horizontal rotation adjustment and inversion control of vehicle-mounted antennas. It relates to an electric inversion mechanism with antenna horizontal rotation function, including a base fixedly mounted on the top of the vehicle from bottom to top, an inversion rotating frame that inverts and rotates relative to the base, a horizontal rotation adjustment device, an antenna support rod, and an antenna mounted on the antenna support rod. The horizontal rotation adjustment device includes a rotating platform bottom plate fixedly mounted on the top of the inversion rotating frame, a rotating bearing seat fixedly mounted on the rotating platform bottom plate, a rotating intermediate shaft rotatably mounted in the rotating bearing seat, a motor reducer connected to the rotating intermediate shaft, and a rotating motor that drives the motor reducer to rotate, which solves the problem that the existing antenna inversion mechanism does not have the antenna horizontal rotation adjustment function and is not convenient to adjust the antenna orientation angle. Although this utility model has a horizontal rotation function, it has the problems of only being able to rotate electrically and not being able to be manually controlled, not being able to work when the power is off, and having a complex structural design, inconvenient installation and maintenance, and high cost.

[0047] like Figure 1-5As shown in the embodiment, a rotating and lodging mechanism for an antenna for a cabin is disclosed, which mainly includes an antenna frame 10, a rotating assembly, and a lodging assembly. Among them, at least one mounting structure 101 is provided on the antenna frame 10 for mounting an antenna 102 for a cabin; the antenna frame 10 is provided on the lodging assembly, and the antenna frame 10 has a rotation stroke around a horizontal axis on the lodging assembly, so as to drive the antenna 102 on the antenna frame 10 to lodging; the lodging assembly is provided on the rotating assembly, and the lodging assembly has a rotation stroke around a vertical axis on the rotating assembly, so as to drive the lodging assembly to rotate on a horizontal plane, and then drive the antenna 102 on the antenna frame 10 to rotate, that is, through the rotating assembly and the lodging assembly, the antenna 102 of the antenna frame 10 can have the functions of lodging and rotating at the same time.

[0048] In this embodiment, the inverted assembly includes a first input shaft 20, a first output shaft 30, a first transmission structure and a hollow first shell 40. One end of the first input shaft 20 is provided with a first driving member 201 and is located outside the first shell 40, and the other end is located inside the first shell 40 after passing through the first shell 40, the middle part of the first output shaft 30 is located inside the first shell 40, and at least one end of the first output shaft 30 is located outside the first shell 40 after passing through the first shell 40. The first input shaft 20 and the first output shaft 30 are both connected to the first shell 40 in a horizontal direction through a bearing 301, and the first input shaft 20 and the first output shaft 30 are connected in transmission by the first transmission structure in the first shell 40.

[0049] A connecting structure is provided on the end of the first output shaft 30 outside the first housing 40, and the antenna frame 10 is fixedly connected to the first output shaft 30 through the connecting structure. In the specific implementation process, the antenna frame 10 is a rod-shaped structure, and the antenna frame 10 is connected to the first output shaft 30 through the connecting structure. There are two implementation methods, specifically:

[0050] The first embodiment is: the connection structure is a locking nut 302, one end of the first output shaft 30 is located inside the first shell 40, and the other end is located outside the first shell 40. The length direction of the antenna frame 10 is perpendicular to the length direction of the first output shaft 30, and one end of the antenna frame 10 is provided with a mounting structure 101, and the other end is directly fixed to the outer end of the first output shaft 30 through the connection structure. Further preferably, both ends of the first output shaft 30 are located outside the first shell 40, that is, both ends of the first output shaft 30 are connected to an antenna frame 10, and then the first output shaft 30 drives the two antenna frames 10 and the antenna 102 to fall synchronously.

[0051] The second embodiment is: both ends of the antenna frame 10 have a mounting structure 101 and an antenna 102, the connection structure is two L-shaped connecting plates 303 and a locking nut 302, the length direction of the antenna frame 10 is parallel to the length direction of the first output shaft 30, and both ends of the first output shaft 30 are located outside the first shell 40. Among them, one end of the first output shaft 30 is fixedly connected to the antenna frame 10 through an L-shaped connecting plate 303, and the other end of the first output shaft 30 is fixedly connected to the antenna frame 10 through another L-shaped connecting plate 303. Specifically, the horizontal side section of the L-shaped connecting plate 303 is fixedly connected to the end of the first output shaft 30 through a locking nut 302, and the vertical side section of the L-shaped connecting plate 303 is fixedly connected to the antenna frame 10 through a locking nut 302, and finally the two antennas 102 can also be driven to fall synchronously through the first output shaft 30. Preferably, a thickened plate is provided between the L-shaped connecting plate 303 and the antenna frame 10 to prevent damage to the antenna frame 10 after long-term use.

[0052] As a preferred solution of the second embodiment, a locking assembly is further provided on the outer wall of the first housing 40, so as to lock the antenna stand 10 when the antenna 102 is horizontal. Specifically, the locking assembly includes a connecting frame 401 provided on the outer wall of the first housing 40, and a latch 402 is slidably connected to the connecting frame 401, and a latch hole configured with the latch 402 is provided on one of the L-shaped connecting plates 303, and when the antenna 102 on the antenna stand 10 is horizontal, that is, when the inversion angle is 0, the latch hole is located on the sliding path of the latch 402.

[0053] In this embodiment, the first input shaft 20 and the first output shaft 30 are perpendicular to each other, and the part of the shaft body of the first input shaft 20 located in the first housing 40 is a worm structure 202. The first transmission structure includes a worm wheel 501 and a connecting key 502. The worm wheel 501 is fixedly sleeved on the first output shaft 30 through the connecting key 502, and the worm wheel 501 is meshed with the worm structure 202 on the first input shaft 20. The use of a worm gear transmission as the first transmission structure can effectively utilize the self-locking property of the worm gear, so that the antenna 102 can be locked at any time when it is inverted at a required position. When the antenna 102 needs to be inverted, the first driving member 201 drives the worm structure 202 on the first input shaft 20 to rotate forward and reverse, thereby driving the worm wheel to move forward and reverse. Since the inner side of the worm wheel is connected to the first output shaft 30 through the connecting key 502, the first output shaft 30 moves forward and reverse accordingly, and the antenna frame 10 and the output shafts at both ends of the first output shaft 30 are rigidly connected together through the L-shaped connecting plate 303. Therefore, driven by the first output shaft 30, the antenna 102 on the antenna frame 10 makes a inverted movement.

[0054] As a preferred embodiment, a tilting dial 403 is fixed on the outer wall of the first shell 40 by bolts, and the tilting dial 403 surrounds the first output shaft 30, so that the tilting angle of the antenna 102 can be obtained more intuitively.

[0055] In this embodiment, the rotating assembly includes a second input shaft 60, a second output shaft 70, a second transmission structure and a hollow second housing 80, and the top end of the second input shaft 60 and the top end of the second output shaft 70 are both located outside the second housing 80, and the bottom end of the second input shaft 60 and the bottom end of the second output shaft 70 are both located inside the second housing 80 after passing through the second housing 80. The second input shaft 60 and the second output shaft 70 are both connected to the second housing 80 in a vertical rotation manner, and the second input shaft 60 and the second output shaft 70 are connected to each other in the second housing 80 through the second transmission structure, and the top end of the second input shaft 60 is provided with a second driving member 601; the first housing 40 is fixedly connected to the top end of the second output shaft 70.

[0056] Specifically, the second transmission structure includes a first slewing bearing 901, a first connecting member 902, a second slewing bearing 903, and a second connecting member 904, which are arranged inside the second housing 80. The inner ring of the first slewing bearing 901 and the inner ring of the second slewing bearing 903 are both fixedly connected to the inner wall of the second housing 80 by bolts, and the outer ring of the first slewing bearing 901 and the outer ring of the second slewing bearing 903 are gears and mesh with each other; the first connecting member 902 and the second connecting member 904 are both annular plate structures, the bottom end of the second input shaft 60 is fixedly connected to the outer ring of the first slewing bearing 901 through the first connecting member 902, and the bottom end of the second output shaft 70 is fixedly connected to the outer ring of the second slewing bearing 903 through the second connecting member 904. When the antenna 102 needs to rotate, the first connecting member 902 and the outer ring of the first slewing bearing 901 rotate together by rotating the second driving member 601 and the second input shaft 60, thereby driving the outer ring of the second slewing bearing 903 meshing therewith to rotate, and then driving the second connecting member 904 and the second output shaft 70 to rotate. Since the second output shaft 70 is rigidly connected to the first housing 40, the inverted assembly rotates accordingly. This embodiment realizes rotational motion by adopting a pair of slewing bearing outer ring gears meshing with each other, which has the advantages of simple structure, easy installation, easy maintenance, cost saving and greater space saving.

[0057] As a preferred embodiment, a locking unit 801 capable of locking the outer ring of the first slewing bearing 901 is provided on the second housing 80, so that the rotation of the lodging assembly can be locked by the locking unit 801 after the lodging assembly is rotated to a suitable angle. In this embodiment, the locking unit 801 is a plum-shaped hand screw threadedly connected to the second housing 80. When the outer ring of the first slewing bearing 901 needs to be locked, the plum-shaped hand screw is screwed to make it press against the outer ring of the first slewing bearing 901 in the second housing 80.

[0058] As a preferred embodiment, a rotating dial 802 is fixed on the outer wall of the second shell 80 by bolts, and the rotating dial 802 surrounds the second output shaft 70, so that the rotation angle of the antenna 102 can be obtained more intuitively.

[0059] In this embodiment, the second housing 80 includes a bottom plate 803 and a rain cover 804 fixedly connected to the bottom plate 803 by bolts, and the top of the rain cover 804 has two through holes corresponding to the second input shaft 60 and the second output shaft 70. A plurality of mounting holes are provided on the bottom plate 803 for fixing the bottom plate 803 on the shelter. Preferably, a support seat 805 is provided on the second housing 80 for supporting the antenna rack 10 when the antenna rack 10 is inverted at an angle of 0.

[0060] In this embodiment, the first driving member 201 and the second driving member 601 are both hand cranks.

[0061] The working principle of the rotating and lodging mechanism for the cabin antenna in this embodiment is as follows:

[0062] When the antenna 102 is not working, the antenna frame 10 is in a flat state, at which time the bottom of the antenna frame 10 rests on the support seat on the bottom plate 803, and the latch 402 in the locking assembly is inserted into the latch hole on the L-shaped connecting plate 303. When working, first unlock the locking assembly to allow the antenna frame 10 to fall freely, and then shake the first driving member 201 on the falling assembly until the angle between the upper surface of the antenna 102 and the horizontal plane is the required value. If necessary, the second driving member 601 of the rotating assembly can be shaken to rotate the antenna 102 and the falling assembly together 360°. After it is in place, tighten the plum thumb screw to lock the rotation.

[0063] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
