A card holder is fixedly installed on the inside of the top shell, and the card holder cooperates with the bottom shell. A plurality of positioning bolts are threadedly installed on the top of the top shell, and a plurality of screw sleeves are fixedly installed on the inside of the bottom shell. The plurality of positioning bolts correspond to the screw sleeves one by one and are threadedly connected with the corresponding screw sleeves. A turntable is rotatably installed on the inside of the top shell, and a mounting frame is fixedly installed on the bottom of the turntable. A plurality of RF connectors are fixedly installed on the bottom of the mounting frame, and a plurality of RF connector arrays are distributed on the mounting frame. The utility model is very simple to operate, and the receiving direction of the array RF connector can be quickly changed.

[0004] In the prior art such as the above-mentioned patent, although installing the array antenna in a shell can effectively protect the antenna, the shell also carries multiple antennas, and the shell is also provided with components for limiting the array antenna. At the same time, connectors are installed on the shell, which can enable the shell to be installed on other devices. The components with different functions on the shell make the shell relatively large, which makes the shell for housing the antenna inconvenient to store or carry. Utility Model Content

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] See also Figure 1-6 An antenna unit array provided by an embodiment of the utility model includes a accommodating box 1 and a driving component. A conical connecting box 2 and a carrier plate 3 are slidably connected along the same straight path in the accommodating box 1. The driving component is used to drive the connecting box 2 and the carrier plate 3 to slide in the opposite direction relative to the accommodating box 1. The connecting box 2 and the carrier plate 3 slide and unfold relative to the accommodating box 1 at the same time, which can save the user's time in unfolding the device and also save storage time.

[0025] Among them, the accommodating box 1 includes a first bottom shell 11 and a first top plate 12, and the first bottom shell 11 and the first top plate 12 are detachably connected. The connecting box 2 includes a second bottom shell 21 and a second top plate 22, and the second bottom shell 21 and the second top plate 22 are detachably connected. By disassembling the first bottom shell 11 and the first top plate 12, the second bottom shell 21 and the second top plate 22 are disassembled, so that the components inside the device can be inspected and repaired conveniently.

[0026] A first slide groove 13 and a second slide groove 14 are provided in the accommodating box 1, and a first slider 5 is slidably connected to the first slide groove 13, and the first slider 5 is fixedly connected to the connecting box 2, and a second slider 6 is slidably connected to the second slide groove 14, and the second slider 6 is fixedly connected to the carrier plate 3. The connecting box 2 can slide on the accommodating box 1 through the sliding of the first slider 5 and the first slide groove 13, and the first slide groove 13 can limit the sliding of the connecting box 2 to prevent the connecting box 2 from sliding out of the accommodating box 1, and the carrier plate 3 can slide on the accommodating box 1 through the sliding of the second slider 6 and the second slide groove 14, and the second slide groove 14 can limit the sliding of the carrier plate 3 to prevent the carrier plate 3 from sliding out of the accommodating box 1.

[0027] Among them, a plurality of ridge plates 31 arranged in parallel are fixedly connected to the carrier plate 3, and an antenna 32 is respectively arranged between each adjacent ridge plate 31. This device has two states, the first being the unfolded state: the connection box 2 and the carrier plate 3 are slid out of the receiving box 1 and fixed, and then the device is fixed to other devices through the screw holes on the connection box 2 to play a role. The ridge plate 31 can make multiple antennas 32 installed and arranged neatly for maintenance. The second is the storage state: after removing this device from other devices, the connection box 2 and the carrier plate 3 are slid so that the connection box 2 and the carrier plate 3 are stored in the receiving box 1. At this time, the volume of the device is significantly reduced compared to the unfolded state, which is more convenient to carry; here, the sliding fixation of the connection box 2 and the carrier plate 3 on the receiving box 1 can be the effect of damping force, or the driving component can stop driving the connection box 2 and the carrier plate 3 to slide and fix them in the desired position.

[0028] The utility model connects the connection box 2 and the carrier plate 3 to the accommodating box 1 by sliding. When the device is to be used, the connection box 2 and the carrier plate 3 can be unfolded from the accommodating box 1 so that the device can be normally connected to other devices to work. When the device is not needed or transported, the connection box 2 and the carrier plate 3 can be slid into the accommodating box 1 so that the space occupied by the device is reduced, the storage space is reduced, and the reduction in volume also makes it convenient for users to transport and carry.

[0029] Among them, the driving component includes a shell 4, a gear 41, a first rack 42, a second rack 43 and a power unit. The shell 4 is fixedly connected to the accommodating box 1, and the gear 41 is rotatably connected to the shell 4. The first rack 42 is fixedly connected to the end of the connecting box 2 away from the accommodating plate, and the second rack 43 is fixedly connected to the end of the carrier plate 3 away from the accommodating box 1. The first rack 42 and the second rack 43 are simultaneously meshed with the gear 41 in a manner in which the tooth surfaces are opposite. The power unit can drive the gear 41 to rotate, and the driving component drives the gear 41 to rotate. The rotation of the gear 41 can make the first rack 42 and the second rack 43 move in reverse at the same time, so that the connecting box 2 and the carrier plate 3 can be unfolded at the same time, and the reverse driving gear 41 can make the connecting box 2 and the carrier plate 3 be stored in the accommodating box 1 at the same time.

[0030] The power unit includes a servo motor 44 and a hydraulic cylinder 45. The servo motor 44 is fixedly mounted on the housing 4. The rotating shaft of the servo motor 44 is coaxially and fixedly connected to the gear 41. The servo motor 44 drives the gear 41 to rotate. When the connecting box 2 and the carrier plate 3 are fully unfolded or stored, the servo motor 44 can self-lock so that the connecting box 2 and the carrier plate 3 stop sliding and are fixed on the accommodating box 1.

[0031] The cylinder seat of the hydraulic cylinder 45 is fixedly installed on the housing 4, and the hydraulic rod of the hydraulic cylinder 45 is fixedly connected to the first rack 42 or the second rack 43. The first rack 42 or the second rack 43 is driven to move by the extension and retraction of the hydraulic rod of the hydraulic cylinder 45. The movement of the first rack 42 or the second rack 43 drives the gear 41 to rotate, and the rotation of the gear 41 causes the other rack to move, thereby achieving the simultaneous expansion or storage of the connection box 2 and the carrier plate 3.

[0032] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
