The cradle head of the present invention will be described in detail with reference to the accompanying drawings. The features of the following examples and embodiments may be combined with each other without conflict.

Fig. 1 is a schematic view of the component modules of a head according to an exemplary embodiment of the present invention. The cloud platform in this embodiment is handheld cloud platform, and of course, in other embodiments, also can be other types of cloud platforms, for example, unmanned aerial vehicle cloud platform. As shown in fig. 1, the handheld tripod head may mainly include a handheld portion 200, a tripod portion 400, and an image forming apparatus 600.

The shape of the handheld portion 200 may be a column shape for holding with one hand, or other shapes for holding with two hands, such as a rectangular parallelepiped shape similar to a card camera, a mobile phone, etc. A plurality of components such as a controller 220, a display 240, a control panel 260, and a wireless transmission module 280 may be disposed on or in the handheld portion 200. The control panel 260 is an interface for interaction between a user and the pan/tilt head. A user can send various control instructions to the pan/tilt head through the control panel 260, for example, lift the imaging device 600 upwards to obtain an image at a higher position; some status information of the cradle head can also be obtained through the control panel 260, for example, whether the cradle head is turned on can be easily known through a power signal lamp. The display screen 240 may display real-time images of the scene being captured by the imaging device 600 to the user in real-time, or may allow the user to view images previously stored in the pan/tilt head apparatus. The wireless transmission module 280 may generally include one or more antennas and a transmitter module and/or a receiver module configured to implement data exchange between the cradle head and the outside.

The outermost layer of the handle 200 is a metal shell having an accommodating space therein. Electronic components such as the controller 220 and the transmitter module and/or the receiver module can be arranged in the accommodating space; the display screen 240 and the control panel 260 may be disposed on the metal housing, for example, a hole or a slot may be formed on the metal housing, and the display screen 240 and the control keys or signal lamps related to the control panel 260 may be embedded in the corresponding hole or slot. The metal housing or a portion thereof may serve as an antenna electrically connected to the transmitter module and/or the receiver module.

The cloud deck 400 may be mounted on the hand-held portion 200 and used to carry the image forming apparatus 600. The dock section 400 may include a plurality of pivots to enable rotation of the dock section 400 in a plurality of directions (relative to the handpiece 200). The image forming apparatus 600 can rotate together with the cloud deck 400, thereby achieving adjustment of the position and state thereof. The imaging device 600 may be a camera, a smart phone with a photographing function, or the like.

Fig. 2 to 5 are schematic structural views of a metal shell according to an embodiment of the invention. The metal housing may be applied to various kinds of pan/tilt head devices, for example, may be used in a hand-held pan/tilt head as shown in fig. 1 as a housing of a hand-held portion 200 thereof. Fig. 2 is a schematic perspective view of a metal shell, in which an insulator is provided in a partial region of the metal shell; FIGS. 3 and 4 are schematic sectional views taken along line A-A, C-C in FIG. 2 to clearly illustrate the relative positions of the metal shell and the insulator; fig. 5 is a plan view of the metal shell, in which the insulator is omitted, to show the connection between the metal shells in different regions.

The metal casing 10 has an accommodating space therein for accommodating various components such as a circuit board, a processor, a transmitter module/receiver module, and the like. The metal shell 10 is provided with a gap G filled with the insulator 30. The metal housing 10 is electrically connected to the transmitter module and/or the receiver module, so that at least a portion of the metal housing 10 can operate as an antenna. Since the metal housing 10 has the antenna function, the number of antennas in the accommodating space of the metal housing 10 can be reduced by a proper amount, or the antennas are not provided. In addition, compared with a plastic shell, the shell made of metal materials is more beautiful in appearance, and the strength, the heat dissipation performance and the like of the shell are enhanced.

The metal case 10 may be a metal plate made of metal or alloy, or may be made by coating a metal material on an insulating base material. The material of the insulator 30 may be a non-conductive material such as plastic or ceramic.

The metal shell 10 may be divided into the first metal shell 12 and the second metal shell 14 by a gap G or an insulator 30, and in the embodiment shown in fig. 2 to 5, the gap G does not completely separate the first and

second metal shells

12 and 14, so that the two metal shells are still electrically connected. One of the first and

second metal housings

12 and 14 is electrically connected to the transmitter module and/or the receiver module to serve as a radiating portion of the antenna, and the other is grounded to serve as a grounding portion of the antenna. In the operating state of the cradle head of the present embodiment, the first metal shell 12 faces upward, the second metal shell 14 faces downward, and the first metal shell 12 is closer to the sky than the second metal shell 14, so that the first metal shell 12 is used as a radiation portion, which can achieve better antenna performance.

In addition to the first and

second metal cases

12 and 14, the metal case 10 may further include a conducting portion 13, and two ends of the conducting portion 13 are respectively connected to the first metal case 12 and the second metal case 14, so that the first and

second metal cases

12 and 14 are electrically connected. The first and

second metal cases

12 and 14 may be integrally formed with the conductive portion 13. In addition, the number of the conduction parts 13 may be 1, 2, or more.

The upper side of the conduction part 13 may be covered with an insulator 30 so that all parts of the insulator 30 are connected as a whole, as shown in fig. 4. The sum of the thickness of the vias 13 and the insulator 30 thereabove may be equal to the thickness of the first metal shell 12 and/or the second metal shell 14, as shown in fig. 3, such that the upper surface of the insulator 30 is flush with the upper surfaces of the first metal shell 12 and the second metal shell 14 adjacent thereto. The conducting portion 13 is not exposed, and the insulator 30 is in the form of a long, thin, flat, and ribbon, as shown in fig. 2, which is advantageous for the appearance of the entire housing.

In practical implementation, the width of the gap G (the distance between the first and

second metal housings

12 and 14 in the vertical direction in fig. 5) may be adjusted between 1 millimeter (mm) and 3 millimeters (mm), and the width of the first metal housing 12 may also be adjusted according to actual needs, for example, may be 9.5 millimeters (mm).

Common antennas in the pan/tilt head include a dual-frequency WiFi antenna (2.4GHZ WiFi antenna and 5.8GHZ WiFi antenna), a GPS antenna, a 5.8G audio antenna, and the like. The metal shell 10 shown in fig. 2 to 5 is connected with a transmitter module and a receiver module, and the performance of the antenna in aspects of return loss, isolation and the like is detected in a laboratory, so that the performance requirements of a dual-frequency WiFi antenna, a GPS antenna and a 5.8G audio antenna can be well met.

Illustratively, in other embodiments, the gap between the first and second metal housings may completely isolate the first and second metal housings such that the two are electrically isolated. That is, the conductive portion as described above may not be present between the first and second metal cases. The first metal housing and/or the second metal housing may be used independently as an antenna. For example, one region of the first metal housing may be connected to the transmitter module and/or the receiver module to serve as a radiating portion of the antenna, and another region of the first metal housing may be connected to ground to serve as a ground portion of the antenna. Meanwhile, the second metal case may or may not be used as an antenna.

The receiving space inside the metal housing 10 may be additionally provided with a built-in antenna, and the gap G and the insulator 30 may serve as a passage for the built-in antenna to transmit and/or receive electromagnetic waves. The built-in antenna can work in different frequency bands and provides wireless transmission service for the holder in the frequency band different from that of the metal shell 10; and can also work in the same frequency band as the metal shell 10 as a backup for the metal shell 10.

Fig. 6 and 7 are schematic structural views of a metal shell according to another embodiment of the invention. The metal housing may be applied to various kinds of pan/tilt head devices, for example, may be used in a hand-held pan/tilt head as shown in fig. 1 as a housing of a hand-held portion 200 thereof. Fig. 6 is a front view thereof showing a positional relationship among the first metal shell 12, the second metal shell 14, and the insulator 30, and fig. 7 is a plan view of the first metal shell 12 thereof. The main structure of the metal shell in this embodiment (except for a few details) can be the same as in the previous embodiments, so the following description focuses on its differences, and the structures not described can be referred to in the previous embodiments.

Referring to fig. 6 and 7, the metal shell includes a first metal shell 12 and a second metal shell 14, and the length of the first metal shell 12 in the transverse direction is significantly smaller than that of the second metal shell 14. The pan and tilt head section 400 and the image forming apparatus 600 and the like as shown in fig. 1 may be mounted at the first metal housing 12. In the operating state of the head, the first metal shell 12 faces upwards, the second metal shell 14 faces downwards, and the user can hold the second metal shell 14.

The first metal shell 12 has a "U" shape in transverse section, and thus may be referred to as a "U" shaped portion. The "U" shape is equal in height throughout the longitudinal direction except at the edges. The first metal housing 12 is electrically connected to the transmitter module and/or the receiver module, and serves as a radiation portion of the antenna.

The lateral cross-section of the second metal shell 14 is in a closed shape, such as a rounded rectangle. The second metal case 14 is grounded and serves as a ground for the antenna.

A gap is provided between the first metal shell 12 and the second metal shell 14, and the gap is filled with an insulator 30. The first and

second metal shells

12, 14 are located on different sides of the insulator 30 and are electrically connected through a conducting portion (which may be as shown in the previous embodiments).

The second metal shell 14, which is relatively large and is used for being held and operated by a user, is the visual center of gravity of the user, and the insulator 30 is arranged on the first metal shell 12, which is relatively small and far away from the user, so that the appearance of the tripod head can be further improved.

Fig. 8 is a graph showing the results of the return loss and isolation tests when the metal case of the embodiment shown in fig. 6 and 7 is operated as an antenna. As can be seen from fig. 8, it can well meet the performance requirements of the dual-frequency WiFi antenna, the GPS antenna, and the 5.8G audio antenna. Fig. 9 is a pattern diagram of the embodiment of fig. 6 and 7 when the metal housing is operating as a GPS antenna. It can be seen from fig. 9 that when operating as a GPS antenna, the radiation direction is primarily in the upper half plane, which facilitates its interaction with GPS satellites.

Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
