Abstract

The utility model provides a dome camera. The dome camera comprises a hemispherical bottom shell, a hemispherical cover plate and a camera module set which are arranged on the hemispherical bottom shell, wherein the hemispherical cover plate and the hemispherical bottom shell jointly form a closed space, and the camera module set is accommodated in the closed space. The dome camera also comprises a heat conduction component which is arranged in the closed space; the heat conduction component includes a plate body, two extending parts and fixing parts; two sides of the plate body are bent and extend downwards so as to form the two extending parts; tail ends of the extending parts extend towards another direction so as to form the fixing parts; the fixing parts are fixed to the hemispherical bottom shell; the camera module set is arranged on the plate body; and the hemispherical bottom shell is an aluminum alloy bottom shell. According to the dome camera of the utility model, heat generated by a chip of the camera module set can be transferred to the hemispherical bottom shell of the camera through the heat conduction component and is dissipated to the outside through the hemispherical bottom shell, and therefore, the heat generated by the chip of the camera module set can be dissipated excellently, and the service life of the chip will not be shortened because of a poor heat dissipation effect.

Description

Dome type camera

Technical field

The utility model relates to a kind of image collecting device, refers to especially a kind of dome type camera.

Background technology

Dome type camera has been widely used in various safety-security areas, and some critical positions of public arena are monitored.

In existing dome type camera, because its inner space is narrow and small, and adopt hermetic mechanism, make the chip of video camera module adopt passive heat radiation, thereby radiating effect undesirable serviceable life that can shorten chip also can affect the stability of whole system.

Utility model content

The utility model proposes a kind of dome type camera, solved the interior not good problem of radiating effect of dome type camera in the past.

The technical solution of the utility model is achieved in that

A kind of dome type camera, comprise hemisphere drain pan, be located at hemisphere cover plate and video camera module on this hemisphere drain pan, the common enclosure space that forms of described hemisphere cover plate and hemisphere drain pan, described video camera module is contained in this enclosure space, this dome type camera also comprises the heat-conducting piece of being located in this enclosure space, this heat-conducting piece comprises a plate body, by the both sides of plate body two extensions that bending extends to form downwards and the fixed part that extended to form to the direction of another extension by the end of each extension, described fixed part and described hemisphere drain pan fix, described video camera module is located on plate body, described hemisphere drain pan is aluminium alloy drain pan.

Preferred version is that described heat-conducting piece is an elastic plate.

Preferred version is to maintain a certain distance between the end of described two fixed parts.

Preferred version is that described hemisphere drain pan is provided with the heat-conduction medium being connected with the fixed part of heat-conducting piece.

Preferred version is to be provided with heat-conduction medium between described plate body and video camera module.

Preferred version is that described hemisphere drain pan has a plane and by upwardly extending arcwall face around plane, described fixed part is located in plane.

The beneficial effects of the utility model are:

The heat that the chip of the module of video camera described in the utility model produces, by heat-conducting piece, conduct to the hemisphere drain pan of video camera, by this hemisphere drain pan, outwards distribute again, thereby the heat that the chip that makes video camera module produces well distributes, prevent that radiating effect is undesirable and shorten serviceable life of chip.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is the structural representation of the utility model dome type camera one preferred embodiment.

In figure:

10, hemisphere drain pan; 11, plane; 13, arcwall face; 20, heat-conducting piece; 21, plate body; 23, extension; 25, fixed part; 50, video camera module; 60, hemisphere lid; 70, heat-conduction medium.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.

As shown in Figure 1, the dome type camera of the present embodiment, it comprises a hemisphere drain pan 10, be located at a heat-conducting piece 20 in this hemisphere drain pan 10, be located at a video camera module 50 and a hemisphere cover body 60 on heat-conducting piece 20.

Described hemisphere drain pan 10 is aluminium alloy drain pan, and it has a plane 11 and by plane 11 upwardly extending arcwall face 13 around.This plane 11 is provided with the heat-conduction medium 70 for being connected with heat-conducting piece 20, and this heat-conduction medium 70 can be the heat-conducting creams such as silica gel.

Described heat-conducting piece 20 comprises a plate body 21, by the both sides of plate body 21 two extensions 23 that bending extends to form downwards and the fixed part 25 that extended to form to the direction of another extension 23 by the end of each extension 23.

Described plate body 21 is the sheet metal that copper coin, aluminium sheet or aluminium alloy plate etc. have better heat-conductive characteristic.In addition, in order further to strengthen the heat-conductive characteristic between described plate body 21 and video camera module 50, also can between described plate body 21 and the bottom of video camera module 50, be coated with described heat-conduction medium 70.

Described extension 23 is extended downward vertically by the both sides of plate body.Each fixed part 25 is vertically extended to the direction of another extension 23 by the end of extension 23.Between the end of described two fixed parts 25, maintain a certain distance.Described extension 23, fixed part 25 can be one-body molded with described plate body 21, and the common elastic plate that forms of three.During assembling, described fixed part 25 can move to the inside according to the bottom of the radian size adjustment extension 23 of hemisphere drain pan 10, until the integral body of heat-conducting piece 20 can enter in this hemisphere drain pan 10 smoothly, its fixed part 25 is contacted with the heat-conduction medium 70 in hemisphere drain pan 10, then fix by fixtures such as screws.The shape setting of this heat-conducting piece 20 adapts to the installation of different scale hemisphere drain pan 10, strengthens its versatility.

Described hemisphere lid 60 matches with described hemisphere drain pan 10, and the enclosure space of video camera module 50 and heat-conducting piece 20 is accommodated in common assembling formation one.

During use, the heat of described video camera module 50 is by the hemisphere drain pan 10 that conducts to video camera of heat-conducting piece 20, by this hemisphere drain pan 10, outwards distribute again, thereby the heat that the chip that makes video camera module 50 produces well distributes, prevent that radiating effect is undesirable and shorten serviceable life of chip, and then affect the stability of whole system.
