Description

Technical Field

[0001] The present application relates to the field of monitoring technology, and in particular to a gun-type camera. Background Art

[0002] In the related art, in order to avoid the influence of humid environment on optical devices, the body of the gun-type camera usually adopts a sealed design. However, during the on-site installation of the gun-type camera, sometimes the body needs to be opened in order to insert the external cables into the body for wiring operations. This will cause the external humid air to enter the body, which may have an adverse effect on the optical devices inside the body. Especially when the on-site installation is carried out in a humid or salt spray environment, the impact on the optical devices of the gun-type camera is extremely serious. For example, moisture itself will affect the imaging effect of the camera module and will also corrode the optical devices; and the salt or acidic substances in the salt spray environment will precipitate on the surface of the optical devices, thereby corroding or even destroying the optical devices.

[0003] Therefore, there is an urgent need for a gun-type camera with better moisture-proof effect to avoid the problem of optical devices coming into contact with humid air during on-site installation. Summary of the invention

In addition, the threading port of the external cable is arranged on the side wall of the second compartment, and during the on-site installation of the gun-type camera, in order to facilitate the insertion of the external cable for wiring operations, the second compartment can be opened for threading. Since the second compartment is isolated from the first compartment, the process of inserting the external cable and wiring will not destroy the sealing of the first compartment, thereby ensuring that the optical device group will never come into contact with the external space. In this way, even if the installation site is in a humid environment or a salt spray environment, it can be ensured that the on-site installation process will not cause the optical device group to come into contact with humid air, thereby providing good protection for the optical device group.

[0039] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field based on the present application belong to the scope of protection of the present application.

[0040] like Figures 1 to 5As shown, an embodiment of the present application proposes a gun-type camera 100. The gun-type camera 100 includes a body 110, a partition component, and an optical device group. The partition component is arranged inside the body 110, and the partition component divides the internal space of the body 110 into a first cabin 101 and a second cabin 102 located behind the first cabin 101. The first cabin 101 is a closed cabin, and a threading hole for inserting external cables is arranged on the side wall of the second cabin 102. The optical device group is arranged in the first cabin 101. In the present application, for the gun-type camera 100, during the process of shooting, the side where the external light enters is the "front" side, and the direction opposite to the "front" is the "rear".

[0041] According to the gun-type camera 100 of the embodiment of the present application, the internal space of its body 110 is divided into a first compartment 101 and a second compartment 102 by a partition component, wherein the first compartment 101 is a sealed compartment with a sealed design, and the optical device group is arranged in the first compartment 101, thereby the optical device group can be well isolated from the external air. In addition, the threading port of the external cable is arranged on the side wall of the second compartment 102. During the on-site installation of the gun-type camera 100, in order to facilitate the insertion of the external cable for wiring operation, the second compartment 102 can be opened for threading. Since the second compartment 102 and the first compartment 101 are isolated, the process of inserting the external cable and wiring will not destroy the sealing of the first compartment 101, thereby ensuring that the optical device group will never come into contact with the external space. In this way, even if the installation site is in a humid environment or a salt spray environment, it can be ensured that the on-site installation process will not cause the optical device group to come into contact with humid air, thereby being able to play a good protective role for the optical device group.

[0042] In the prior art, for cameras with pigtails, when the interface on the pigtail is connected to an external cable, a waterproof junction box needs to be configured separately to ensure that the interface on the external cable will not be invaded by rainwater. In contrast, the second compartment 102 of the gun-type camera 100 of the embodiment of the present application can play the role of a waterproof junction box, so there is no need to set up a separate waterproof junction box, which is conducive to cost saving.

[0043] In some embodiments of the present application, Figure 2As shown, the fuselage 110 includes a fuselage main shell 111, a front frame 112, a front frame sealing ring 113 and a rear cover 114, wherein the partition component is arranged inside the fuselage main shell 111, the front frame 112 is connected to the front side of the fuselage main shell 111, the front frame 112, the fuselage main shell 111 and the partition component together form a first cabin 101, the front frame sealing ring 113 is arranged at the connection between the front frame 112 and the fuselage main shell 111, the rear cover 114 is connected to the rear side of the fuselage 110 body, and the partition component, the fuselage main shell 111 and the rear cover 114 together form a second cabin 102. Thus, the components form a first cabin 101 and a second cabin 102 located inside the fuselage 110. Among them, the rear cover 114 is connected to the fuselage main shell 111 in an open and disassembled manner, and the second cabin 102 can be opened by disassembling the rear cover 114, so as to facilitate the operation of inserting external cables and wiring.

[0044] Furthermore, the fuselage 110 may further include a rear cover sealing ring 115, which is disposed at the connection between the rear cover 114 and the fuselage main housing 111. The provision of the rear cover sealing ring 115 is conducive to improving the sealing performance of the second compartment 102.

[0045] In some embodiments of the present application, Figures 3 to 5 As shown, the partition component is a circuit board 120 disposed inside the body 110, that is, the circuit board 120 of the gun-type camera 100 also serves as a partition component, and the circuit board 120 is provided with a wiring port for connecting with an external cable. The gun-type camera 100 also includes a circuit board sealing ring 125 disposed at the connection between the circuit board 120 and the body main shell 111. In this embodiment, the circuit board 120 is used as a partition component, and the external cable can be directly connected to the wiring port of the circuit board 120, which makes the connection of the external cable more convenient. On the other hand, the circuit board 120 is used as a partition component, so that there is no need to set up other partition structures, which is conducive to simplifying the structure of the gun-type camera 100 and saving manufacturing costs.

[0046] In some embodiments of the present application, a water retaining bar 1121 is provided on the top of the front frame 112. In most cases, the body 110 of the gun-type camera 100 is tilted forward and downward. In this posture, the water retaining bar 1121 can block the rainwater flowing forward from the rear of the top of the body 110, so that the rainwater flows down from both sides of the body 110 and does not flow to the front side of the front frame 112. In this way, it is possible to avoid the problem that the dust on the top of the body 110 carried by the rainwater flows through the front side of the front frame 112, leaving stains on the lens glass on the front side of the front frame 112, thereby avoiding the problem that the stains will cause the shooting effect of the gun-type camera 100 to deteriorate.

[0047] In some embodiments of the present application, the optical device group may include a camera module 130, wherein the camera module 130 includes a lens and an image sensor. Further, the optical device group may also include a light board module 140, which is used to generate illumination light to increase the brightness of the environment, thereby facilitating improved shooting effects.

[0048] In some embodiments of the present application, Figure 6 As shown, the gun-type camera 100 further includes a mounting plate 150, a mounting tube 160 and a driving device 170, wherein the mounting tube 160 is rotatably connected to the mounting plate 150, the camera module 130 is mounted on the mounting tube 160, and the driving device 170 is connected to the mounting tube 160, and the driving device 170 is configured to drive the mounting tube 160 to rotate relative to the mounting plate 150. In the related art, the gun-type camera 100 has a conventional monitoring mode and a channel monitoring mode. In the conventional monitoring mode, the image sensor is in a horizontal placement state, and in the channel monitoring mode, the image sensor is in a longitudinal placement state. In the embodiment of the present application, the driving device 170 can drive the mounting tube 160 to rotate relative to the mounting plate 150, and the camera module 130 and the mounting tube 160 rotate synchronously, thereby, the angle of the image sensor can be adjusted, so that the gun-type camera 100 can realize the conversion between the conventional monitoring mode and the channel monitoring mode.

[0049] Furthermore, a limiting boss 161 is provided on the mounting tube 160, and the gun-type camera 100 further includes a first micro switch 181 and a second micro switch 182 provided on the mounting plate 150, and the first micro switch 181 and the second micro switch 182 are both electrically connected to the driving device 170, and the first micro switch 181 and the second micro switch 182 jointly define the rotation angle range of the mounting tube 160 relative to the mounting plate 150. Specifically, there may be an angle interval of 90° between the first micro switch 181 and the second micro switch 182, and when the limiting boss 161 on the mounting tube 160 contacts the corresponding micro switch, the micro switch controls the driving device 170 to stop running. In this way, the gun-type camera 100 can accurately control the rotation angle of the image sensor when switching between the normal monitoring mode and the channel monitoring mode.

[0050] Further, the driving device 170 may include a motor 171, a first gear 172, and a second gear 173, wherein the motor 171 is mounted on the mounting plate 150, the first gear 172 is disposed on the rotating shaft of the motor 171, the second gear 173 is fixed to the mounting cylinder 160, and the first gear 172 and the second gear 173 are meshed. When the motor 171 is working, the first gear 172 and the second gear 173 can drive the mounting cylinder 160 to move. Specifically, the motor 171 may be a micro variable speed motor 171, which has the advantages of small size and light weight.

[0051] In some embodiments of the present application, the gun-type camera 100 further includes a sunshade 191 disposed on the top of the body 110. The sunshade 191 can suppress the interference of sunlight on the lens to improve the clarity of the image and the degree of color reproduction. In addition, the sunshade 191 can also play a role in rain and sun protection.

[0052] In some embodiments of the present application, the gun-type camera 100 further includes an ugliness-obstructing cover 192 connected to the front side of the body 110 . The ugliness-obstructing cover 192 can cover the mounting holes on the front side of the body 110 , etc., thereby improving the aesthetics of the gun-type camera 100 .

[0053] In some embodiments of the present application, the threading opening includes a first threading opening 1021 disposed at the top of the second compartment 102 and a second threading opening 1022 disposed at the bottom of the second compartment 102. When installing the gun-type camera 100, a suitable threading opening can be selected according to the installation method. Specifically, when the camera bracket 200 is connected to the bottom of the body 110, the gun-type camera 100 can be suitable for support installation (please refer to Fig.13 ) and wall mounting (please refer to Fig.14 ) and other installation methods, in this case, the external cable is inserted from the second threading port 1022, and at the same time, the first threading port 1021 can be closed by the external thread plug 300. In this case, since the second threading port 1022 is in a downward state, it can prevent rainwater from entering the second compartment 102. When the camera bracket 200 is connected to the top of the fuselage 110, the gun-type camera 100 can be applied to indoor ceiling installation (please refer to Fig.15 ) installation method, at this time, the external cable is inserted from the first threading port 1021, and at the same time, the second threading port 1022 can be closed using the external thread plug 300.

[0054] In some embodiments of the present application, the gun-type camera 100 also includes an SD card holder arranged in the second compartment 102, that is, the SD card holder can be arranged in the second compartment 102, so that it is convenient to insert an SD card to expand the storage space of the gun-type camera 100.

[0055] In some embodiments of the present application, the gun-type camera 100 further includes a control button for controlling the zoom of the lens disposed in the second compartment 102. When the gun-type camera 100 is installed on site, it is usually necessary to adjust the focal length of the lens so that the focal length of the lens is within a desired range. Therefore, the control button for controlling the zoom of the lens can be disposed in the second compartment 102 for easy operation.

[0056] It is understandable that a reset button for controlling the gun-type camera 100 to restore factory settings, a control button for controlling the rotation of the camera module 130 , etc. may also be disposed in the second compartment 102 .

[0057] In some embodiments of the present application, Figure 1 , Figures 7 to 10 As shown, the gun-type camera 100 further includes a camera bracket 200. The camera bracket 200 includes a mounting base 210, a first bracket 220, a cross-axis component 230 and a second bracket 240, wherein a mounting opening 211 is provided on the mounting base 210, the first bracket 220 is mounted on the mounting opening 211, a first wire-passing hole 221 is formed on the first bracket 220, the cross-axis component 230 has a first mounting portion 231 and a second mounting portion 232, the first mounting portion 231 is connected to the first bracket 220 in a manner that it can rotate around a first axis L1, a second wire-passing hole 233 is formed on the cross-axis component 230, the second mounting portion 232 is connected to the second bracket 240 in a manner that it can rotate around a second axis L2, the second axis L2 and the first axis L1 are in a spatially vertical relationship, and a third wire-passing hole 241 is formed on the second bracket 240. The camera bracket 200 in this embodiment is an external camera bracket, which can be used to be installed with the gun-type camera 100. Specifically, it can be installed at the bottom or top of the fuselage 110 according to the installation method. In addition, the setting of the cross-axis component 230 ensures that the attitude angle of the gun-type camera 100 can be adjusted in various installation methods. In addition, after the gun-type camera 100 is assembled with the camera bracket 200, the external cable can be sequentially passed through the first wire hole 241 on the first bracket 220, the second wire control 233 on the cross-axis component 230, and the third wire hole 241 on the second bracket 240, and finally the external cable is passed through the first wire threading port or the second wire threading port and introduced into the second cabin 102, thereby ensuring that the external cable can pass through the inside of the camera bracket 200, so that the camera bracket 200 can protect the camera tail line.

[0058] In some embodiments of the present application, the camera bracket 200 further includes an outer sleeve 250, which is disposed between the first bracket 220 and the second bracket 240, and is sleeved on the outside of the cross-axis member 230. The outer sleeve 250 can block ultraviolet rays from irradiating the external cable, thereby preventing the cable sheath of the external cable from aging due to long-term exposure to ultraviolet rays.

[0059] In some embodiments of the present application, Fig.11 As shown, the first bracket 220 includes a first chassis 222, a first cylinder 223 and a first connecting arm 224. The first chassis 222 is rotatably arranged at the mounting mouth 211. The mounting mouth 211 is also provided with a first adjusting screw 260 for locking the first chassis 222 to the mounting mouth 211. A through hole communicating with the internal space of the first cylinder 223 is provided on the first chassis 222. The first connecting arm 224 is provided at one end of the first cylinder 223 away from the first chassis 222. The first connecting arm 224 is used to connect to the first mounting portion 231. In this embodiment, the first chassis 222 is rotatably arranged at the mounting mouth 211. The mounting mouth 211 is provided with a first adjusting screw 260 for locking the first chassis 222 to the mounting mouth 211. When the first adjusting screw 260 is loosened, the first chassis 222 can rotate relative to the mounting opening 211, and the rotation angle of the first bracket 220 around the central axis of the mounting base 210 can be adjusted. After the adjustment is completed, the first adjusting screw 260 can be tightened to maintain the adjusted angle. It can be seen that the central axis of the mounting base 210 constitutes the third axis L3, and combined with the first axis L1 and the second axis L2, the camera bracket 200 has three adjustable rotation axes, so that the posture angle of the gun-type camera 100 can be adjusted more flexibly.

[0060] Furthermore, an annular dovetail groove 2221 may be provided on the edge of the first chassis 222 , and accordingly, the mounting opening 211 of the mounting base 210 fits into the annular dovetail groove 2221 , thereby realizing a rotatable connection between the first chassis 222 and the mounting opening 211 .

[0061] In some embodiments of the present application, Fig. 9 , Fig.11As shown, a first threaded hole 2241 is provided on the first connecting arm 224, and a first shaft hole 2311 is provided on the first mounting portion 231. The first connecting arm 224 and the first mounting portion 231 are connected by a second adjusting screw 270 that penetrates the first shaft hole 2311 and fits in the first threaded hole 2241. When the second adjusting screw 270 is loosened, the first connecting arm 224 of the first bracket 220 and the first mounting portion 231 of the cross shaft member 230 can rotate freely around the first axis L1, and when the second adjusting screw 270 is tightened, the angle between the first connecting arm 224 and the first mounting portion 231 can be fixed, thereby making the rotation angle between the cross shaft member 230 and the first bracket 220 adjustable.

[0062] In some embodiments of the present application, the first connecting arm 224 is further provided with a first annular bevel gear 2242 arranged around the first threaded hole 2241, and the first mounting portion 231 is further provided with a second annular bevel gear 2312 arranged around the first shaft hole 2311, and the second annular bevel gear 2312 is meshed with the first annular bevel gear 2242. In this embodiment, the first annular bevel gear 2242 on the first connecting arm 224 is meshed with the second annular bevel gear 2312 on the first mounting portion 231, so that unexpected relative rotation between the first connecting arm 224 and the first mounting portion 231 can be avoided, thereby facilitating the maintenance of the relative angle between the cross shaft component 230 and the first bracket 220.

[0063] In some embodiments of the present application, a first annular positioning groove 2222 is provided on one side of the first chassis 222 close to the cross-axis member 230, and one end of the outer sleeve 250 close to the first bracket 220 is limited in the first annular positioning groove 2222. The first annular positioning groove 2222 has a limiting effect on one end of the outer sleeve 250, which is conducive to ensuring the position stability of the outer sleeve 250. In addition, since one end of the outer sleeve 250 extends into the first annular positioning groove 2222, it is also conducive to avoiding a light-transmitting gap between the outer sleeve 250 and the first bracket 220, so as to better block ultraviolet rays.

[0064] In some embodiments of the present application, Figure 8 , Fig. 9 and Fig.12As shown, the second bracket 240 includes a second chassis 242, a second cylinder 243 and a second connecting arm 244. A through hole communicating with the internal space of the second cylinder 243 is provided on the second chassis 242. The second connecting arm 244 is provided at one end of the second cylinder 243 away from the second chassis 242. The second connecting arm 244 is used to connect with the second mounting portion 232. Specifically, a second threaded hole 2441 is provided on the second connecting arm 244, and a second shaft hole 2321 is provided on the second mounting portion 232. The second connecting arm 244 and the second mounting portion 232 are connected by a third adjusting screw 280 penetrating the second shaft hole 2321 and matched with the second threaded hole 2441. When the third adjusting screw 280 is loosened, the second connecting arm 244 of the second bracket 240 and the second mounting portion 232 of the cross-axis component 230 can rotate freely around the second axis L2, and when the third adjusting screw 280 is tightened, the angle between the second connecting arm 244 and the second mounting portion 232 can be fixed, thereby making the rotation angle between the cross-axis component 230 and the second bracket 240 adjustable.

[0065] In some embodiments of the present application, a third annular bevel gear 2442 arranged around the second threaded hole 2441 is further provided on the second connecting arm 244, and a fourth annular bevel gear 2322 arranged around the second shaft hole 2321 is further provided on the second mounting portion 232, and the fourth annular bevel gear 2322 is meshed with the third annular bevel gear 2442. In this embodiment, the third annular bevel gear 2442 on the second connecting arm 244 is meshed with the fourth annular bevel gear 2322 on the second mounting portion 232, so that unexpected relative rotation between the second connecting arm 244 and the second mounting portion 232 can be avoided, thereby facilitating the maintenance of the relative angle between the cross shaft component 230 and the second bracket 240.

[0066] In some embodiments of the present application, a second annular positioning groove 2421 is provided on one side of the second chassis 242 close to the cross-axis member 230, and one end of the outer sleeve 250 close to the second bracket 240 is limited in the second annular positioning groove 2421. The second annular positioning groove 2421 has a limiting effect on one end of the outer sleeve 250, which is conducive to ensuring the position stability of the outer sleeve 250. In addition, since one end of the outer sleeve 250 extends into the second annular positioning groove 2421, it is also conducive to avoiding a light-transmitting gap between the outer sleeve 250 and the second bracket 240, so as to better block ultraviolet rays.

[0067] In some embodiments of the present application, the outer sleeve 250 is a bellows, which is retractable. Therefore, when the second adjusting screw 270 and / or the third adjusting screw 280 need to be adjusted, the bellows can be compressed in its length direction, so that the second adjusting screw 270 and / or the third adjusting screw 280 are exposed, so that the installer can make corresponding angle adjustments. After the adjustment is completed, the bellows can be expanded in its length direction, so that the bellows can maximize the role of blocking ultraviolet rays. In addition, based on the outer sleeve 250 being a retractable bellows, when the bellows is expanded, its two ends are respectively tightened in the first annular positioning groove 2222 and the second annular positioning groove 2421, so that the structural stability of the bellows can be ensured.
