Description

Technical Field

[0001] This application belongs to the technical field of camera design, and particularly relates to an audio-visual device. Background Art

[0002] In the petrochemical field, in order to monitor whether there is any phenomenon of leakage in the operation site, it is usually necessary to use an audio-visual device (such as a camera) that can collect both sound and images to conduct on-site monitoring. This audio-visual device generally includes an acoustic component and a camera component disposed in the installation cavity of the audio-visual device, and the acoustic component is used to collect sound, while the camera component is used to collect images.

[0003] Since this audio-visual device is applied in dangerous scenarios such as petrochemical industries where flammable and explosive substances exist, this audio-visual device usually needs to meet explosion-proof requirements. However, due to the generally low power of the acoustic component and the generally high power of the camera component, the total power of the devices installed in the installation cavity is relatively large, and thus the generated thermal effect is relatively large, that is, more heat is released. This easily affects the normal operation of the acoustic component and the camera component, that is, it easily affects the normal operation of this audio-visual device. At the same time, it also easily affects the explosion-proof ability of this audio-visual device.

[0004] In summary, the audio-visual device related to the related technology has problems of relatively low explosion-proof ability and easy occurrence of abnormal operation. Utility Model Content

[0005] This application discloses an audio-visual device to solve the problems of relatively low explosion-proof ability and easy occurrence of abnormal operation existing in the audio-visual device related to the related technology.

[0006] To solve the above technical problems, this application adopts the following technical solutions:

[0007] An audio-visual device includes a first housing, a second housing, an acoustic component, and a camera component.

[0008] The first housing is provided with a viewing window hole and a sound pickup hole at intervals. The first housing and the second housing are connected to enclose a first cavity. The acoustic component is disposed in the first cavity, and the acoustic component is disposed opposite to the sound pickup hole.

[0009] One side of the second housing facing the viewing window hole protrudes with a mounting post. The end face of the mounting post abuts against the inner wall of the first housing, and the acoustic component is sleeved on the mounting post. The mounting post is provided with a mounting hole, and the mounting hole is disposed opposite to the viewing window hole. The camera component is disposed in the mounting hole so that the camera component faces the viewing window hole.

[0010] The technical solutions adopted by this application can achieve the following beneficial effects:

[0011] In this application, since the acoustic component is disposed in the first cavity and the imaging component is disposed in the mounting hole, that is, the acoustic component and the imaging component are disposed in two relatively independent spaces. This makes the power of the devices installed in each space relatively small, and thus the thermal effect generated is relatively small, that is, the heat released is less. This can avoid affecting the normal operation of the acoustic component and the imaging component, that is, avoid affecting the normal operation of the audio-video device. At the same time, this can improve the explosion-proof ability of the audio-video device to a certain extent. Therefore, the audio-video device disclosed in this application can solve the problems of relatively low explosion-proof ability and easy abnormal operation existing in the audio-video device related to the related art.

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application.

[0029] The following will, in conjunction with the accompanying drawings, elaborate in detail on the audio - visual device disclosed in the embodiments of this application through specific embodiments and their application scenarios.

[0030] Please refer to Figures 1 to 12 , this application discloses an audio - visual device. The disclosed audio - visual device includes a first housing 100, a second housing 200, an acoustic component 300, and a camera component.

[0031] The first housing 100 and the second housing 200 are the peripheral structures of the audio - visual device, which can protect other components of the audio - visual device. For example, they can protect the acoustic component 300 and the camera component provided inside the audio - visual device. The camera component is used to collect images, and the acoustic component 300 is used to collect sounds, so that the audio - visual device has the functions of both shooting and recording at the same time. Specifically, the acoustic component 300 includes a pickup 330. The pickup 330 is equivalent to a microphone, and the pickup 330 can achieve the effect of the acoustic component 300 collecting sounds.

[0032] The first housing 100 is provided with a window hole 110 and a sound pickup hole 120 at intervals. The window hole 110 facilitates the imaging of the imaging component, and the sound pickup hole 120 facilitates the acoustic component 300 to collect sound. The first housing 100 and the second housing 200 are connected to enclose a first cavity 130. The acoustic component 300 is arranged in the first cavity 130, and the acoustic component 300 is arranged opposite to the sound pickup hole 120. Specifically, the sound pickup 330 is arranged opposite to the sound pickup hole 120 to facilitate the sound pickup 330 to collect sound better.

[0033] To prevent water vapor from entering the first cavity 130 through the sound pickup hole 120 and thus corrode the acoustic component 300, the audio-visual device may further include a fourth seal 740 and a waterproof film 750. The waterproof film 750 covers the sound pickup hole 120 to prevent water vapor from entering the first cavity 130 through the sound pickup hole 120. At the same time, the fourth seal 740 is arranged around the sound pickup hole 120, and the fourth seal 740 is in sealing cooperation with both the inner wall of the first housing 100 and the acoustic component 300 to further prevent water vapor from entering the first cavity 130 through the sound pickup hole 120, thereby preventing the corrosion of the acoustic component 300.

[0034] Optionally, the number of the sound pickup holes 120 may be multiple, and the number of the sound pickups 330 may also be multiple. Each of the sound pickup holes 120 may be arranged at intervals around the window hole 110, and each of the sound pickup holes 120 may correspond to each of the sound pickups 330 one by one, or each sound pickup 330 corresponds to multiple sound pickup holes 120 to facilitate the acoustic component 300 to collect clearer sound.

[0035] Optionally, a third connection hole 150 may be formed in the first housing 100, and a fourth connection hole 291 may be formed in the second housing 200. The audio-visual device may further include a second connector 820. One end of the second connector 820 passes through the third connection hole 150 and is detachably connected to the fourth connection hole 291 to detachably connect the first housing 100 and the second housing 200. Of course, the first housing 100 and the second housing 200 may also be adhesively connected.

[0036] Optionally, a first guiding structure may be provided between the first housing 100 and the second housing 200. During the process of specifically connecting the first housing 100 and the second housing 200, the first guiding structure can play a guiding and positioning role to make it easier to connect the first housing 100 and the second housing 200.

[0037] An installation post 210 protrudes from the side of the second housing 200 facing the window hole 110. The end face of the installation post 210 abuts against the inner wall of the first housing 100, that is, the installation post 210 abuts against and is relatively sealed with the inner wall of the first housing 100. Optionally, the installation post 210 and the first housing 100 may be connected by a first threaded connector, and the installation post 210 may be a cylindrical structure.

[0038] The acoustic component 300 can be sleeved on the mounting post 210, that is, the acoustic component 300 is arranged around the mounting post 210. The mounting post 210 can play a role in limiting the acoustic component 300. At the same time, a mounting hole 220 is formed on the mounting post 210. The mounting hole 220 is arranged opposite to the window hole 110, and the mounting hole 220 is relatively independent and sealed from the first cavity 130. The imaging component is arranged in the mounting hole 220 so that the imaging component faces the window hole 110, facilitating the imaging component to capture the external environment through the window hole 110.

[0039] In this application, since the acoustic component 300 is arranged in the first cavity 130 and the imaging component is arranged in the mounting hole 220, that is, the acoustic component 300 and the imaging component are arranged in two relatively independent spaces. This makes the power of the devices installed in each space relatively small, and thus the thermal effect generated is relatively small, that is, less heat is released. This can avoid affecting the normal operation of the acoustic component 300 and the imaging component, that is, avoid affecting the normal operation of the audio-visual device. At the same time, this can improve the explosion-proof ability of the audio-visual device to a certain extent. Therefore, the audio-visual device disclosed in this application can solve the problems of relatively low explosion-proof ability and easy abnormal operation existing in the audio-visual device involved in the related art.

[0040] Optionally, the window hole 110 can be a square hole, and the sound pickup hole 120 can be a circular hole. Of course, the embodiments of this application do not make specific limitations on this.

[0041] Optionally, the imaging component can only include a transparent window 410 and a camera 430. The mounting hole 220 has a first end close to the window hole 110. The transparent window 410 is arranged at the first end. The transparent window 410 can be specifically adhered to the first end by an adhesive material to ensure the sealing performance. The camera 430 is arranged in the mounting hole 220, and the camera 430 is arranged facing the transparent window 410.

[0042] In another embodiment, the imaging component can further include a pressing plate 420. The pressing plate 420 is arranged in the mounting hole 220. In the shooting direction of the imaging component, the pressing plate 420 can press the transparent window 410, that is, the pressing plate 420 can apply a pressing force to the transparent window 410 to ensure the setting stability of the transparent window 410 and the sealing performance between the transparent window 410 and the mounting hole 220. At the same time, a part of the camera 430 can pass through the pressing plate 420 and is arranged facing the transparent window 410, that is, the pressing plate 420 can limit the camera 430 so that the camera 430 is arranged more stably facing the transparent window 410.

[0043] Optionally, please refer to Figure 2 and Figure 3, the mounting hole 220 may include a first mounting hole 221 and a second mounting hole 222 that are connected and communicate with each other. The cross-sectional area of the first mounting hole 221 may be smaller than that of the second mounting hole 222. The transparent window 410 may be disposed in the first mounting hole 221, that is, among the first mounting hole 221 and the second mounting hole 222, the first mounting hole 221 is closer to the window hole 110. And the second mounting hole 222 has a stepped surface 223 close to the first mounting hole 221. The stepped surface 223 extends in a direction perpendicular to the shooting direction of the imaging assembly. The pressing plate 420 may be mounted on the stepped surface 223, and the transparent window 410 abuts against the pressing plate 420. That is, at this time, the contact area between the pressing plate 420 and the stepped surface 223 is relatively large. Furthermore, the installation between the pressing plate 420 and the stepped surface 223 is relatively stable. Furthermore, the pressing force applied by the pressing plate 420 to the transparent window 410 is relatively balanced and stable. Of course, the cross-sectional areas of each part of the mounting hole 220 may also be equal.

[0044] Optionally, the pressing plate 420 and the stepped surface 223 may be connected by a second threaded connector. At the same time, to facilitate the connection between the pressing plate 420 and the stepped surface 223, a second guiding structure may be provided between the pressing plate 420 and the stepped surface 223. During the specific process of connecting the pressing plate 420 and the stepped surface 223, the second guiding structure can play a role in guiding and positioning, so that the pressing plate 420 and the stepped surface 223 are more easily connected.

[0045] Optionally, the camera 430 may include a connected lens 431 and a mounting assembly 432. Components such as a heat dissipation component and a photosensitive chip may be provided on the mounting assembly 432. The pressing plate 420 may be provided with a through hole 421. The lens 431 passes through the through hole 421 and is disposed toward the transparent window 410. The mounting assembly 432 is connected to the pressing plate 420, that is, the pressing plate 420 can serve as the mounting base of the camera 430, thereby ensuring the setting stability of the camera 430. Of course, the camera 430 and the pressing plate 420 may only have a sleeved relationship.

[0046] Optionally, the mounting assembly 432 and the pressing plate 420 may be connected by a third threaded connector. At the same time, to facilitate the connection between the mounting assembly 432 and the pressing plate 420, a third guiding structure may be provided between the mounting assembly 432 and the pressing plate 420. During the specific process of connecting the mounting assembly 432 and the pressing plate 420, the third guiding structure can play a role in guiding and positioning, so that the mounting assembly 432 and the pressing plate 420 are more easily connected.

[0047] Optionally, the audio-visual device may further include a circuit board assembly 500. The second housing 200 has a second cavity 230. The second cavity 230 communicates with the mounting hole 220. The circuit board assembly 500 is disposed in the second cavity 230. That is, the imaging assembly and the circuit board assembly 500 are installed in the same space, and the imaging assembly is electrically connected to the circuit board assembly 500. That is, the circuit board assembly 500 can supply power to the imaging assembly to ensure that the imaging assembly can work properly.

[0048] The second housing 200 is provided with a first wire passing hole 240. The first wire passing hole 240 can communicate the first cavity 130 and the second cavity 230. At this time, one end of the first cable 310 of the acoustic assembly 300 can pass through the first wire passing hole 240 and is electrically connected to the circuit board assembly 500, so that the circuit board assembly 500 can supply power to the acoustic assembly 300 through the first cable 310 to ensure that the acoustic assembly 300 can work properly. It can be seen that the acoustic assembly 300 and the imaging assembly in this application are powered by the same circuit board assembly 500, which can simplify the structural complexity of the audio-visual device. Of course, the acoustic assembly 300 and the imaging assembly can also be powered by different circuit board assemblies 500, that is, different circuit board assemblies 500 can be provided in both the first cavity 130 and the second cavity 230.

[0049] Optionally, the first cable 310 and the first wire passing hole 240 are in sealed cooperation to prevent the water vapor entering the first cavity 130 from entering the second cavity 230 and the mounting hole 220 through the first wire passing hole 240 at the same time, that is, to prevent the water vapor from adhering to the inner surface of the transparent window 410 described above, thereby avoiding affecting the imaging effect of the imaging assembly. Of course, the first cable 310 and the first wire passing hole 240 may not be in sealed cooperation. At this time, as long as it is ensured that the first cavity 130 is sealed relative to the external environment.

[0050] Optionally, the inner wall of the second cavity 230 and the circuit board assembly 500 can be connected by a fourth threaded connector. At the same time, for the convenience of connecting and installing the circuit board assembly 500, a fourth guiding structure can be provided between the inner wall of the second cavity 230 and the circuit board assembly 500. During the specific process of connecting the inner wall of the second cavity 230 and the circuit board assembly 500, the fourth guiding structure can play a guiding and positioning role to make it easier for the inner wall of the second cavity 230 and the circuit board assembly 500 to be connected.

[0051] Optionally, please refer to Figure 12, the circuit board assembly 500 may specifically include a first circuit board 510 and a second circuit board 520 that are electrically connected. The first circuit board 510 may be respectively connected to the acoustic component 300 and the camera component. The first circuit board 510 may control the operation of the acoustic component 300 and the camera component, and the first circuit board 510 may be connected to the inner wall of the second cavity 230 through the above-mentioned fourth threaded connector. The second circuit board 520 may be connected to an external cable to supply power to the acoustic component 300 and the camera component.

[0052] Optionally, the first circuit board 510 and the second circuit board 520 may be connected through a third connector 830. Specifically, the first circuit board 510 and the second circuit board 520 may be respectively connected to both ends of the third connector 830. Since the third connector 830 has a certain length, this enables a certain spacing between the first circuit board 510 and the second circuit board 520 to prevent the heat generated during the operation of the first circuit board 510 and the second circuit board 520 from not dissipating in time, thereby avoiding mutual influence.

[0053] Optionally, to enable the audio-visual device to implement a communication function, the audio-visual device may further include an antenna and an antenna cover 600. The antenna cover 600 is connected to the outer surface of the second housing 200 to enclose an antenna cavity 610, and the antenna is disposed in the antenna cavity 610 and may be specifically fixed in the antenna cavity 610. The second housing 200 is further provided with a third wire passing hole communicating the second cavity 230 and the antenna cavity 610. One end of the second cable of the antenna may pass through the third wire passing hole and be electrically connected to the circuit board assembly 500.

[0054] In another embodiment, since the power of the devices in the first cavity 130 is relatively small, that is, the first cavity 130 can be considered an intrinsically safe cavity, and the power of the antenna is usually also small, therefore, the antenna cavity 610 can also be considered an intrinsically safe cavity. To ensure the explosion-proof ability of the audio-visual device, the second housing 200 is further provided with a second wire passing hole 250 communicating the first cavity 130 and the antenna cavity 610, that is, the antenna cavity 610 is connected to the first cavity 130 through the second wire passing hole 250. At this time, one end of the second cable of the antenna may sequentially pass through the second wire passing hole 250 and the first wire passing hole 240 and be electrically connected to the circuit board assembly 500, and both the first cable 310 and the second cable are in sealing fit with the first wire passing hole 240.

[0055] In this embodiment, one end of the second cable of the antenna can be connected to the circuit board assembly 500 by passing through the first wire passing hole 240, that is, the first wire passing hole 240 is reused in the embodiment of the present application to improve the utilization rate of the first wire passing hole 240. Of course, in other embodiments, one end of the second cable of the antenna may pass through an additional third wire passing hole provided on the second housing 200 and be connected to the circuit board assembly 500.

[0056] Optionally, the radome 600 and the second housing 200 may be connected by a fifth threaded connector. At the same time, to facilitate the connection between the radome 600 and the second housing 200, a fifth guiding structure may be provided between the radome 600 and the second housing 200. During the specific process of connecting the radome 600 and the second housing 200, the fifth guiding structure can play a role in guiding and positioning, making it easier to connect the radome 600 and the second housing 200.

[0057] Optionally, the number of the first wire passing holes 240 may be one.

[0058] In another embodiment, since the number of the first cables 310 of the acoustic component 300 is usually large, for example, 128, to avoid an overly large aperture of the first wire passing hole 240, the number of the first wire passing holes 240 may be at least two. That is, at least two first wire passing holes 240 may be spaced apart on the second housing 200, and at least one first cable 310 is provided in each first wire passing hole 240. That is, multiple first cables 310 may be separately arranged in different first wire passing holes 240. After such an arrangement, the aperture of each first wire passing hole 240 is relatively small, and thus it is easier to make a sealing arrangement with the first cables 310.

[0059] Optionally, the number of the first wire passing holes 240 may be four, and the first wire passing holes 240 are arranged at intervals around the mounting post 210. The four first wire passing holes 240 can meet the design requirements of this application. Of course, the number of the first wire passing holes 240 may also be less or more.

[0060] Optionally, the second housing 200 may include a first sub - housing 260 and a second sub - housing 270. The first sub - housing 260 is provided with a mounting post 210 and a first wire passing hole 240. The first sub - housing 260 and the second sub - housing 270 are connected to enclose the second cavity 230. Specifically, the first sub - housing 260 and the second sub - housing 270 may be detachably connected by a sixth threaded connector, and an avoidance space may be provided on the second sub - housing 270. When the sixth threaded connector connects the first sub - housing 260 and the second sub - housing 270, the end of the sixth threaded connector may be arranged in the avoidance space.

[0061] The first sub - housing 260 has an annular mating surface 261 extending in a first direction, which is the direction in which the first sub - housing 260 faces away from the first housing 100. The second sub - housing 270 can be sleeved on the annular mating surface 261, and the mating gap between the second sub - housing 270 and the annular mating surface 261 is less than or equal to a preset mating gap. Optionally, the preset mating gap can be 1.5 millimeters. At this time, since the annular mating surface 261 has a certain dimension in the first direction and the mating gap between the second sub - housing 270 and the annular mating surface 261 is small, the annular mating surface 261 is equivalent to an explosion - proof surface. That is, the second cavity 230 formed by connecting the first sub - housing 260 and the second sub - housing 270 is equivalent to an explosion - proof cavity, which can further improve the explosion - proof ability of the audio - visual device. Of course, the first sub - housing 260 may not have an annular mating surface 261 extending in the first direction. That is, at this time, the first sub - housing 260 and the second sub - housing 270 can be directly detachably connected by a sixth threaded connector.

[0062] Optionally, a guide post 262 can be protrudingly provided on the first sub - housing 260. Correspondingly, a guide hole can be provided on the second sub - housing 270. During the process of specifically connecting the first sub - housing 260 and the second sub - housing 270, the guide post 262 and the guide hole are in guiding cooperation, that is, the guide post 262 and the guide hole can play an auxiliary installation role to make it easier for the first sub - housing 260 and the second sub - housing 270 to be connected.

[0063] Optionally, please refer to Figure 2 and Figure 3 , to ensure the sealing performance of the second cavity 230, a third seal 730 can be provided between the first sub - housing 260 and the second sub - housing 270. The third seal 730 is in sealing cooperation with both the first sub - housing 260 and the second sub - housing 270, thereby ensuring the sealing performance of the second cavity 230.

[0064] Optionally, please refer to Figure 5 , the audio - visual device can further include a first seal 710. At least one of the first housing 100 and the second housing 200 is provided with a first groove 280. At least a part of the first seal 710 is disposed in the first groove 280 to limit the first seal 710, and the first seal 710 is in sealing cooperation with both the first housing 100 and the second housing 200, which enables the first cavity 130 to be sealed relative to the external environment to protect the acoustic component 300. Of course, the audio - visual device may not include the first seal 710.

[0065] Optionally, please refer to Figure 5, the audio-visual device may further include a second seal 720. A second groove 211 is formed in at least one of the end face of the mounting post 210 and the first housing 100. At least a part of the second seal 720 is disposed in the second groove 211 to limit the second seal 720, and the second seal 720 is in sealing cooperation with both the first housing 100 and the mounting post 210, so that the mounting hole 220 can be sealed relative to the external environment and the first cavity 130 to protect the imaging component. Of course, the audio-visual device may not include the second seal 720.

[0066] Optionally, the acoustic component 300 may not be connected to the first housing 100. To ensure the setting stability of the acoustic component 300, the acoustic component 300 can be limited by the limiting structure in the first cavity 130 and the mounting post 210.

[0067] In another embodiment, the audio-visual device may further include a first connecting member 810. The first connecting member 810 may be a threaded connecting member. A first connecting hole 320 may be formed in the acoustic component 300, and a second connecting hole 140 may be formed in the inner wall of the first housing 100. The second connecting hole 140 may be a blind hole with a threaded structure.
