Specific Embodiment

[0033] The principles and features of the present utility model are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present utility model and are not used to limit the scope of the present utility model. In the following paragraphs, the present utility model is described more specifically by way of example with reference to the accompanying drawings. According to the following description and the claims, the advantages and features of the present utility model will be clearer. It should be noted that the accompanying drawings are all in a very simplified form and use non-precise scales, and are only used to facilitate and clearly assist in explaining the purpose of the embodiments of the present utility model.

[0034] Embodiment 1

[0035] As Figures 1 - 4 shown, this embodiment provides a housing assembly, which is used as the housing of an audio-video signal generating device, and it includes a housing body 1. A heat dissipation window 11 and a display screen 2 are provided on the housing body 1. A hidden handle 12 is also provided on the housing body 1. By providing a hidden handle on the housing body, it makes the audio-video signal generating device convenient to hold and has a beautiful appearance.

[0036] In the above technical solution, the upper end of the casing body 1 is an inclined surface that slopes in the front-rear direction, and the horizontal height of the front upper end of the casing body 1 is lower than the horizontal height of the rear upper end of the casing body 1. The display screen 2 is arranged in the middle of the upper end of the casing body 1, so that the display screen is also inclined along with the upper end surface of the casing body, so that the display screen is displayed forward and upward, facilitating the experimenter to observe the display information on the display screen. Preferably, in this embodiment, the inclination angle of the upper end surface of the casing body is 10-45°, preferably 30°.

[0037] In the above technical solution, heat dissipation ribs 13 are convexly provided on both sides of the upper end of the casing body 1 located on both sides of the display screen 2 and form a friction surface (convex points as small as sesame seeds can be evenly distributed), so that the upper end of the casing body can dissipate heat, and at the same time, it is convenient to carry it after forming the friction surface.

[0038] In the above technical solution, a threaded groove hole 14 is further recessed in the middle of the lower end of the casing body 1. The threaded groove hole 14 is used for detachably connecting with a pan-tilt bracket (such as the pan-tilt bracket used by a camera), so that the audio-visual signal generating device can be installed on the pan-tilt bracket for use, and the position and inclination angle of the audio-visual signal generating device can be adjusted more flexibly.

[0039] In the above technical solution, support feet 3 are respectively arranged at the four corners of the lower end of the casing body 1. Its structure is simple, so that the audio-visual signal generating device can be placed on the experimental table, and its bottom wall is in a suspended state for easy heat dissipation. Specifically, the support feet 3 are rubber columns, and their damping effect is good.

[0040] As Figure 5 and Figure 6 shown, in the above technical solution, heat dissipation windows 11 are arranged on the side walls and the bottom wall on both the left and right sides of the casing body 1, and a heat dissipation fan 4 that blows air outward is arranged at a position corresponding to at least one of the heat dissipation windows 11 inside the casing, and a dust-proof net 5 is covered at a position corresponding to the remaining heat dissipation windows 11 inside the casing body 1, so that the heat dissipation and dust-proof effect of the audio-visual signal generating device is good (so that the air entering the casing body will be filtered by the dust-proof net, and the heat dissipation fan blows out the air inside the casing body to accelerate the air flow inside the casing body, thereby improving the heat dissipation effect).

[0041] See details Figure 5 and Figure 6, in the above technical solution, the hidden handle 12 is arranged in the middle of the front side and / or the rear side of the housing body 1, which is convenient to hold. Specifically, the hidden handle 12 is a groove recessed in the housing body 1 and in the shape of a lying "J", with a simple structure and not easy to fall off when held (when picking up and placing, the palm of the corresponding hand faces upward, and the other four fingers except the thumb extend into the groove, and the four fingers are bent to hook with the hidden handle, so that the housing can be picked up and placed with one hand without lifting).

[0042] The groove wall of the hidden handle 12 in the above technical solution is a friction surface, which can further improve the stability when holding it and prevent the audio-visual signal generating device from falling due to hand slipping.

[0043] As Figure 7 shown, the installation method of the display screen 2 at the upper end of the housing body 1 in this embodiment is as follows. In this embodiment, a mounting hole 15 for mounting the display screen 2 is provided in the middle of the upper end of the housing body 1. An annular mounting ring groove 151 is recessed in the hole wall of the mounting hole 15. A flexible washer 152 (with a ring groove 1521 on the inner hole wall of the flexible washer 152) is arranged in the mounting ring groove 151. The edge of the display screen 2 extends into the ring groove 1521 and is clamped. The flexible washer (which can be a silicone washer) can not only play a sealing role, but also provide a buffering effect on the display screen, so as to improve the shock absorption effect of the display screen on the housing body. In addition, the upper end surface of the display screen is lower than the upper end surface of the housing body, which can further protect the display screen.

[0044] Specifically, the hidden handle is arranged at the middle position of the front upper end of the housing body. A power switch, a power plug interface and a plurality of signal input / output ports are arranged at the rear end of the housing body, which will not be elaborated here.
