In a further technical solution, a groove wall of the second annular groove 130, which is far away from the light supplement lampshade body 110, is a step-shaped structure, the step-shaped structure may include a first step 131 and a second step 132, the first step 131 abuts against a groove bottom of the first annular groove 230, a fourth gap is provided between the second step 132 and the groove bottom of the first annular groove 230, the first adhesive layer 400 includes a fourth adhesive ring 440, the fourth adhesive ring 440 is provided in the fourth gap, and the fourth adhesive ring 440 is fixedly connected with the second adhesive ring 420.
Referring to fig. 8 again, the length of the second step 132 is d, and the effective explosion-proof bonding length of the first bonding layer 400 is a + b + c + d by adding the fourth bonding ring 440. Under the circumstance, the effective explosion-proof bonding length of the first bonding layer 400 can be further increased by additionally arranging the fourth bonding ring 440, and then the volumes of the light supplement lamp protection cover 100 and the lens protection cover 200 are further reduced on the premise of meeting the explosion-proof requirement of the explosion-proof camera.
In this application, the first adhesive ring 410, the third adhesive ring 430, the second adhesive ring 420, and the fourth adhesive ring 440 are sequentially connected, and the first adhesive layer 400 is hermetically connected to the light compensating lamp protective cover 100 and the lens protective cover 200. The first adhesive ring 410, the third adhesive ring 430, the second adhesive ring 420, and the fourth adhesive ring 440 may be formed by coating an adhesive (e.g., glue) and then solidifying the adhesive, wherein the first adhesive ring, the third adhesive ring, the second adhesive ring, and the fourth adhesive ring are integrated.
In the above scheme, light filling lamp protection casing 100 includes that fixed continuous hinders light zone and light filling printing opacity district, and the mode that forms to hinder light zone and light filling printing opacity district has the multiple, in this application embodiment, light filling lamp protection casing 100 can include fixed continuous printing opacity piece 160 and light-shading piece 170, and light-shading piece 170 cover locates outside printing opacity piece 160, can set up the opening on the lateral wall of light-shading piece 170 to form light filling printing opacity district, the part except the opening of light-shading piece 170 forms light-shading district. The opening sets up with light filling printing opacity district one-to-one, and the quantity in light filling printing opacity district is unanimous with open-ended quantity promptly, and open-ended quantity can be one or more, and this application does not do the restriction to this. Optionally, the light-transmitting member 160 may be made of a transparent PC material, and the light-shielding member 170 may be made of a black PC material.
Alternatively, the light-transmitting member 160 and the light-shielding member 170 may be fixedly coupled by screws. Or, the light-transmitting member 160 and the light-shielding member 170 can be made into an integrated structure through a secondary injection molding process, so that when the inside of the camera explodes, the internal pressure is not easy to make the light-transmitting member 160 and the light-shielding member 170 fall off, and further the light-compensating lamp protective cover 100 has an explosion-proof effect, so that the housing assembly can be used for an explosion-proof camera.
In order to make the light supplement lamp protection cover 100 in the present application be used for an explosion-proof camera, the thickness of the light supplement lamp protection cover 100 needs to meet explosion-proof requirements, the thickness of the light supplement lamp protection cover 100 having an open position is minimum, in order to make the thickness of the light supplement lamp protection cover 100 meet explosion-proof requirements, in an optional embodiment, the thickness of the light-transmitting member 160 can be made to be greater than or equal to the thickness needed to meet explosion-proof requirements. However, the overall thickness of the light supplement lamp protection cover 100 is large due to the structure, and thus the size, weight and cost of the light supplement lamp protection cover 100 are increased.
For this, the light-transmitting member 160 may be provided with a protrusion 161, the protrusion 161 may be inserted into the opening, an outer wall surface of the protrusion 161 may be coplanar with an outer wall surface of the light-shielding member 170, or an outer wall surface of the protrusion 161 may protrude from the outer wall surface of the light-shielding member 170. Under this condition, the thickness stack of light-transmitting member 160 and the two of piece 170 that hides reaches explosion-proof requirement can, for light-transmitting member 160 does not be equipped with the structure of bellying 161, the structure of the light-transmitting member 160 that is equipped with bellying 161 can reduce the whole thickness of light filling lamp protection casing 100, and then reduces the weight and the cost of light filling lamp protection casing 100.
The light supplement lamp shield 100 and the lens shield 200 may be fixedly connected by a first adhesive layer 400. Under this kind of structure, the light that the light filling lamp launches can shine on light-transmitting member 160, partial light can reflect or refract the inside that gets into light-transmitting member 160, and conduct in the inside of light-transmitting member 160, under the condition that first adhesive linkage 400 is light-transmitting structure, the inside partial light of light-transmitting member 160 can see through the inside that first adhesive linkage 400 enters into lens protection casing 200, the inside light that enters into lens protection casing 200 can cause harmful effects to the formation of image of camera, for this reason, in the embodiment of the application, first adhesive linkage 400 can be light-tight structure, avoid the light that the light filling lamp launches to enter into lens protection casing 200 through first adhesive linkage 400, that is to say, the light of light filling lamp can not directly shoot into lens protection casing 200, only make the light in external monitoring area can shoot into lens protection casing 200, lens protection casing 200 can supply outside light to see through, avoid the interference of the light of light filling lamp. Specifically, the first adhesive layer 400 may include a light blocking medium.
The mode of assembling light filling lamp protection casing 100 to the camera has a variety, for example screw connection or bonding, but, screw connection's mode can cause light filling lamp protection casing 100 to be impaired, and the connected mode that bonds needs to carry out some glue to light filling lamp protection casing 100, and in the concrete assembling process of camera, the operation process of carrying out some glue to light filling lamp protection casing 100 is comparatively complicated, and the operation degree of difficulty is higher, is unfavorable for the assembly of camera.
For this reason, in the embodiment of the present application, the chassis assembly may further include an explosion-proof connector 300, and the explosion-proof connector 300 is fixedly connected to an end of the light supplement lamp shield 100 far from the lens shield 200. Optionally, the explosion-proof connector 300 may be made of metal. Under this condition, can assemble the casing subassembly to the camera through explosion-proof connecting piece 300 on, can avoid directly causing the damage to light filling lamp protection casing 100 when assembling light filling lamp protection casing 100 to the camera.
Specifically, the light supplement lamp shield 100 may include a light supplement lamp cover body 110 and a third connecting portion 140 that are fixedly connected, the explosion-proof connecting member 300 may include an explosion-proof connecting member body 310 and a fourth connecting portion 320 that are fixedly connected, and the third connecting portion 140 and the fourth connecting portion 320 may be fixedly connected through the second adhesive layer 500, so that the explosion-proof connecting member 300 is fixedly connected to the light supplement lamp shield 100. The explosion-proof connector 300 may have an explosion-proof engagement surface for explosion-proof engagement with a corresponding connection portion of the camera. Alternatively, the second adhesive layer 500 may use an epoxy adhesive.
