Although the camera body 1 and the cover assembly 2 made of metal affect the transmission of the antenna signal, the transparent cover 3 made of plastic does not affect the transmission of the antenna signal.
In the present embodiment, the antenna assembly 5 is disposed in the longitudinal cavity and the first cavity enclosed by the camera body 1, the upper cover assembly 2, and the transparent cover 3 by the first bracket assembly 4, and at least a part of it is disposed in the first cavity, so that the antenna signal can be transmitted to the outside of the housing through the transparent cover 3.

The part of the antenna support 51 in the first cavity is an effective functional area of the antenna support, which is visible from the transparent cover 3 after the assembly is completed, and in order to avoid the antenna pattern affecting the appearance of the camera, the antenna may be preferably formed on the inner surface of the antenna support 51, i.e. a side surface thereof facing the first support assembly 4, but not a side surface thereof facing the transparent cover 3.

Wherein the arc base 511 is used for being fixed to the first bracket component 4 through a fastening structure such as a screw, and the antenna bracket side wall 512 extends longitudinally from the arc base 511 to extend from the longitudinal cavity to the circular cavity to form an effective functional area of the antenna bracket, so as to be able to transmit signals through the transparent cover. The antenna holder side wall 512 also has an arc shape that matches the circumferential shape of the first holder side wall 42 and the spherical shape of the transparent cover, so as to be able to be disposed in the gap between the first holder assembly 4 and the upper cover assembly 2 and in the gap between the first holder assembly 4 and the transparent cover 3 as shown in fig. 1.
As shown in fig. 4, the antenna is formed on the inner surface of the antenna holder sidewall 512, and the inner surface of the antenna holder sidewall 512 is further provided with a cable 513 connected to the antenna.
As shown in fig. 5, a cable 513 is inserted through the center hole of the first frame member 4 to be connected to the main board of the camera body 1, and a video signal generated by the main board is transmitted to the antenna via the cable 513 and is transmitted out via the transparent cover 3.
The mainboard sets up in camera main part 1, consequently, first bracket component 4 adopts the shape of ring, and its centre bore is used for being located vertical cavity and the cable in the first cavity to wear to establish to camera main part 1.
As shown in fig. 5, in order to fix the position of the cable 513 passing through the central hole, the edge of the first bracket sidewall 42 further includes:

Fig. 6 is an exploded view of a third embodiment of the camera with built-in antenna assembly of the present invention. Fig. 7 is an enlarged view of a portion of the first bracket assembly of fig. 6.
As shown in fig. 6, the camera of the present embodiment further includes:
the lens assembly 6 is pivotally fixed on the first support assembly 4, a pivot axis of the lens assembly 6 is parallel to a diameter direction of the first support assembly 4, so that the lens assembly 6 has a freedom degree of a pitch angle relative to the first support assembly 4, wherein two ends of the diameter of the lens assembly 6 are provided with pivot points 61, and a connecting line between the two pivot points 61 is the pivot axis of the lens assembly 6.

That is, the first bracket sidewall 42 may be arcuate less than a semicircle. Preferably, the arc angle of the arc base 511 is less than 180 °, i.e. it is an arc less than a semicircle, so as to avoid the shooting area of the lens assembly 6.
As can be seen from fig. 1, in the present embodiment, the lens assembly 6 is disposed in the first cavity through the first frame assembly 4, the antenna frame side wall 512 and the first frame side wall 42 are disposed in the gap between the lens assembly 6 and the transparent cover 1, and the antenna frame side wall 512 and the first frame side wall 42 partially wrap the lens assembly 6.
In a preferred embodiment, the thickness of the gap between the lens assembly 6 and the transparent cover 3 is at least twice the thickness of the antenna mount sidewall 512. For example, the minimum gap between the transparent cover 3 and the lens assembly 6 is 3.5mm, the antenna bracket 51 is a common plastic piece, the average wall thickness is 1.5mm, and the thickness of the laser-etched antenna is small and can be ignored. The gap between the transparent cover 3 and the lens assembly 6 and the first carrier assembly 4 is therefore sufficient to set down the entire antenna carrier assembly. And the size and the shape of the antenna support do not have special requirements, and from the performance of the antenna, the performance of the antenna is in direct proportion to the area of the antenna subjected to laser etching, so that the larger the effective area capable of being used for the laser etching is, the better the performance of the antenna is. Therefore, the effective area of the antenna support needs to be maximized in the limited gap between the transparent cover 3 and the lens assembly 6, and in this embodiment, the sidewall 512 of the antenna support for the laser-etched antenna is a spherical surface imitating the transparent cover, which is an optimal solution in the gap.

Therefore, the first frame component 4 is fixed to the second frame component 7, and the axes of the first frame component and the second frame component coincide with each other, so that the lens component 6 has a rotational degree of freedom in the circumferential direction by bringing the first frame component 4.
In order to avoid displacement of the antenna support assembly during rotation, in the present embodiment, in addition to the antenna support assembly being coupled to the first support assembly through the circular arc base 511, the antenna support side wall 512 is also in contact with the first support side wall 42 through a snap structure.

In the present embodiment, since the first chassis assembly 4 can have a rotational degree of freedom in the circumferential direction, the snap structure between the antenna chassis side wall 512 and the first chassis side wall 42 provides a circumferential direction limit in addition to a radial direction limit, and thus, the abutment of the antenna chassis side wall 512 and the first chassis side wall 42 in the radial direction can be ensured, and circumferential displacement occurring at the time of circumferential rotation can be prevented.
Through two ascending spacing connections of side, antenna bracket component 5 is unchangeable with first bracket component 4's relative position is fixed, also further guarantees with the relative position of second bracket component 7 is fixed unchangeable, then it is thick to carry out the angle modulation of circumference direction through second bracket component 7, antenna bracket component 5 is unchangeable with the regional relative position of translucent cover formation of image, can not influence the formation of image of camera.
