Description

Technical Field

[0001] This utility model relates to the field of security monitoring technology, and in particular to a security monitoring device and its monitoring module. Background Technology

[0002] Security surveillance cameras typically feature daytime monitoring, nighttime monitoring, and motion detection capabilities. Their monitoring modules usually include infrared LEDs (IR LEDs), white LEDs, red and blue indicator lights, PIR (Passive Infrared) sensor components, and microphone (MIC) holes. The large number of optical components necessitates careful structural layout to ensure their performance while preventing interference between them. For example, IR LEDs and white LEDs are generally positioned on the left and right sides of the camera to address vignetting issues. Simultaneously, the light sources need to be kept away from the PIR sensor components, as these are highly susceptible to heat; overheating can lead to false triggering and increased power consumption. Therefore, spatially arranging the numerous optical components is extremely challenging, and they are prone to mutual interference.

[0003] Therefore, it is necessary to provide a monitoring module and security monitoring device that can solve the spatial layout problem and reduce the mutual interference between optical components, so as to solve the above problems. Utility Model Content

[0004] One objective of this invention is to provide a monitoring module that can solve spatial layout problems and reduce mutual interference between optical components.

[0005] Another objective of this invention is to provide a security monitoring device that can solve spatial layout problems and reduce mutual interference between optical components.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: a monitoring module is provided, comprising a first circuit board, a light-shielding component, and a light guide column; wherein, the first circuit board is provided with a plurality of spaced-apart lamps; the light-shielding component is connected to the first circuit board and surrounds each of the lamps; the light guide column has a light-transmitting structure, one end face of the light guide column is provided with a plurality of arc-shaped light-incident surfaces, and the other end face of the light guide column forms an arc-shaped light-outceasing surface; the end of the light guide column with the light-incident surfaces is connected to the light-shielding component, and each light-incident surface corresponds to each of the lamps; the light emitted by each lamp enters the light guide column through the light-incident surface corresponding to that lamp, passes through the light guide column, and exits through the light-outceasing surface.

[0007] Preferably, both the light-incident surface and the light-exit surface are recessed towards the center of the light guide column. The light-exit surface adopts a concave design, which not only increases the light-exit area but also enhances the diffusion effect of the light source. In this way, after the light emitted by any lamp enters the light guide column, it is diffused by the light-incident and light-exit surfaces of the light guide column, making the light emitted from the light-exit surface of the light guide column uniform in brightness and uniform in appearance. Therefore, multiple lamps can share a single light guide column, thereby reducing the number of lamp sources, solving the spatial layout problem, and reducing the mutual influence between the optics of the devices.

[0008] Preferably, the end face of the light guide column away from the light incident surface is provided with multiple light emitting surfaces, each light emitting surface corresponding to each light incident surface, and each light emitting surface is concave towards the center of the light guide column to form an arc-shaped structure. The multiple concave light emitting surfaces not only increase the light emitting area but also enhance the diffusion effect of the light source. As a result, after the light emitted by any lamp enters the light guide column, it is diffused by the light incident and light emitting surfaces of the light guide column, making the light emitted from the light emitting surface of the light guide column uniform in brightness and uniform in appearance radiation. Therefore, multiple lamps can share a single light guide column, thereby reducing the number of lamp sources, solving the spatial layout problem, and reducing the mutual influence between the optical components.

[0009] Preferably, the light-emitting surface has a non-glossy structure, which serves to both cover the light and concentrate it, thereby solving the light spot problem, making the light radiation more uniform, and meeting the optical requirements.

[0010] Preferably, the light-emitting surface is provided with a bubble texture. This serves two purposes: firstly, it acts as a mask, and secondly, the bubble texture has a light-focusing effect, thereby solving the light spot problem, making the light radiation more uniform, and meeting the optical requirements.

[0011] Preferably, the light-emitting surface is provided with a plurality of concave structures, which are arranged in a ring around the center of the light-emitting surface, thereby playing a role in shielding and focusing light, thus solving the problem of light spot, making the light radiation more uniform, and meeting the optical requirements.

[0012] Preferably, the light-shielding member is provided with a first receiving hole, and each of the lamp bodies is located in the first receiving hole. One end of the light guide post with the light-incident surface extends into the first receiving hole, and the light guide post and the light-shielding member are sealed together. The light-incident surface is spaced apart from each of the lamp bodies. The light-shielding member is used to prevent light from leaking to the side from the bottom of the light guide post, thereby avoiding optical interference between the devices.

[0013] Preferably, the first circuit board has two spaced-apart lamp bodies of different types; the end face of the light guide column has two light-incident surfaces, which are respectively arranged opposite to the two lamp bodies, and the light-incident surfaces and the lamp bodies are spaced apart along the light-emitting direction of the light guide column. The light emitted by any lamp body enters the light guide column through its corresponding light-incident surface. After being diffused by the light-incident and light-emitting surfaces of the light guide column, the light emitted from the light-emitting surface of the light guide column has uniform brightness, creating a two-lamp effect and meeting the optical requirements of the device.

[0014] Preferably, the monitoring module further includes a second circuit board, a camera assembly, and a sensor assembly; wherein the second circuit board is spaced apart from the first circuit board and the two are electrically connected; the camera assembly is mounted on the second circuit board and passes through the first circuit board, and the camera assembly is spaced apart from the light guide column; the sensor assembly is mounted on the second circuit board and spaced apart from the camera assembly.

[0015] Preferably, the light-shielding member is further provided with a second receiving hole, and the camera assembly passes through the second receiving hole and is sealed to the light-shielding member.

[0016] Correspondingly, this utility model also provides a security monitoring device, which includes a base and a monitoring module as described above. The base has a hollow structure, and an mounting plate is provided on the outer side of the base. The monitoring module is installed inside the base, and the light guide column passes through the mounting plate and exposes the light-emitting surface of the base.

[0017] Preferably, the security monitoring device further includes a mounting base and a rotating bracket, the rotating bracket being mounted on the mounting base and the base being rotatably connected to the rotating bracket.

[0018] Compared with the prior art, the monitoring module of this utility model is equipped with a light guide column with a light-transmitting structure. One end of the light guide column has multiple light-incident surfaces with an arc structure, and the other end of the light guide column forms a light-emitting surface. Each light-incident surface corresponds to a lamp body. In this way, the light emitted by each lamp body enters the light guide column through the light-incident surface corresponding to that lamp body. After the diffusion effect of the light-incident surface with an arc structure, the light emission angle is increased. Therefore, the light can pass through the entire light guide column and be emitted through the light-emitting surface, making the brightness of the entire light-emitting surface of the light guide column uniform. This ensures that the light emitted through the light guide column meets the optical requirements of the device. Therefore, it is possible to realize a scheme in which multiple lamp bodies share a single light guide column, thereby reducing the number of lamp sources and components. This not only solves the spatial layout problem but also reduces the mutual interference between the optical components.

[0019] Correspondingly, a security monitoring device with the monitoring module of this utility model also has the above-mentioned technical effects. Attached Figure Description

[0032] Combination Figures 1-4 As shown, in one embodiment of this utility model, a security monitoring device 100 is provided. The security monitoring device 100 includes a monitoring module 110, a base 120, a rotating bracket 130, and a mounting base 140. The mounting base 140 is used to install the security monitoring device 100 at the point of use, and its structure is a conventional structure in the art. The rotating bracket 130 is mounted on the mounting base 140 and has two spaced-apart connecting ears 131. The base 120 is rotatably connected to the two connecting ears 131 of the rotating bracket 130; the structure and connection method between the two are both conventional in the art. The monitoring module 110 is mounted on the base 120, and the rotation of the base 120 drives the monitoring module 110 to rotate, thereby achieving monitoring.

[0033] Continue to combine Figures 1-3 As shown, in a preferred embodiment, the base 120 and the two connecting ears 131 are integrally formed into a spherical or hemispherical structure, making the appearance of the security monitoring device 100 simpler and more aesthetically pleasing. Specifically, the two connecting ears 131 of the rotating bracket 130 have an arc-shaped structure, and the protrusion directions of the two connecting ears 131 are opposite. The base 120 is provided with two mounting sides 122, both of which are planar and parallel, and the surface of the base 120 between the two mounting sides 122 has an arc-shaped structure. When the base 120 is connected to the rotating bracket 130, it is pivotally connected to the two connecting ears 131 through its two mounting sides 122. At this time, the edge of each connecting ear 131 aligns with the edge of a mounting side 122, so that the two connecting ears 131 and the arc-shaped surface of the base 120 form a spherical structure, such as... Figure 1-2 As shown. Of course, the structure between the base 120 and the rotating support 130 is not limited to that in this embodiment.

[0034] Combination Figure 2-3 As shown, in this embodiment, the outer side of the base 120 is also provided with a mounting plate 121. The mounting plate 121 is located between the two mounting sides 122, and the surface where the mounting plate 121 is located intersects with the surface where the two mounting sides 122 are located. The mounting plate 121 is used to install the monitoring module 110.

[0035] In one specific embodiment, the base 120 is composed of a detachably connected front shell 120a and a rear shell 120b, and the detachable connection between the two is a conventional method in the art. A mounting plate 121 is disposed on the front shell 120a, while the mounting side 122 is jointly formed by the combined front shell 120a and rear shell 120b. Of course, the structure of the base 120 is not limited to that in this embodiment.

[0036] The following is combined Figures 3-10As shown, in one embodiment of this utility model, the monitoring module 110 includes at least a first circuit board 111, a light-shielding member 112, a lamp body 113, and a light guide column 114. Multiple lamp bodies 113 are mounted on the first circuit board 111 at intervals. The lamp bodies 113 can be of different types or the same type, flexibly configured according to the needs of the monitoring module 110. The light-shielding member 112 is connected to the first circuit board 111 and surrounds each lamp body 113, such as... Figure 9 As shown. The light guide column 114 has a light-transmitting structure, and one end face of the light guide column 114 is provided with multiple light-incident surfaces 1141 in an arc shape, while the other end face of the light guide column 114 forms a light-emitting surface 1142. The end of the light guide column 114 with the light-incident surfaces 1141 is connected to the light-shielding member 112, and each light-incident surface 1141 corresponds to each lamp body 113, while the light-incident surfaces 1141 and each lamp body 113 are spaced apart along the light-emitting direction. In this way, the light emitted by each lamp body 113 enters the light guide column 114 through the light-incident surface 1141 corresponding to that lamp body 113, and after being diffused by the arc-shaped light-incident surface 1141, the light emission angle increases. Therefore, the light can pass through the entire light guide column 114 and exit through the light-emitting surface 1142, as shown. Figure 10 As shown, this ensures uniform brightness across the entire light-emitting surface 1142 of the light guide 114, meeting the optical performance requirements of the device. This allows multiple lamps 113 to share a single light guide 114, thereby reducing the number of lamp sources, solving spatial layout problems, and also resolving the issue of mutual optical interference between devices.

[0037] See below. Figure 11 As shown, in one embodiment of this utility model, the light-emitting surface 1142 is an arc-shaped structure that is concave inward as a whole. That is, both the light-incident surface 1141 and the light-emitting surface 1142 are concave in the middle of the light guide column 114. In this way, the light-incident surface 1141 and the light-emitting surface 1142 of the light guide column 114 form a structure similar to a biconcave lens, thereby enhancing the diffusion effect of light.

[0038] Specifically, it can be combined with Figure 10As shown, when the light emitted by the lamp body 113 is diffused by the light-incident surface 1141, it enters the entire light guide column 114 for transmission, which expands the transmission range of the light and allows the light to exit through the entire light-emitting surface 1142. Then, the concave light-emitting surface 1142 diffuses the light outward again, thereby increasing the light-emitting area and enhancing the diffusion effect of the light source, thus making the brightness of the light-emitting surface 1142 of the entire light guide column 114 uniform. Therefore, after the light emitted by any lamp body 113 enters the light guide column 114, the light emitted through the light guide column 114 has uniform brightness and uniform external radiation. Thus, multiple lamp bodies 113 can share a single light guide column 114, thereby reducing the number of lamp sources while meeting the optical performance requirements of the device, solving the space layout problem, and reducing the mutual influence between the optical components.

[0039] The following is combined Figures 5-8 As shown, in one embodiment of this utility model, the end face of the light guide column 114 away from the light incident surface 1141 is provided with a plurality of light emitting surfaces 1142. Each light emitting surface 1142 is correspondingly arranged with each light incident surface 1141, and each light emitting surface 1142 has an arc-shaped structure that is concave in the middle of the light guide column 114. That is, the light incident surface 1141 and the light emitting surface 1142 are arranged opposite to each other and are all concave in the middle of the light guide column 114, thereby forming a structure similar to a biconcave lens. In a specific embodiment, the light incident surface 1141 and the light emitting surface 1142 are preferably arc-shaped, but this is not a limitation. This structural arrangement also increases the light emitting area and enhances the diffusion effect of the light source.

[0040] Specific combination Figure 10 As shown, the light emitted by any lamp body 113 is diffused through its corresponding light-incident surface 1141 and then enters the entire light guide column 114 for transmission. This expands the transmission range of the light, allowing the light to exit through multiple light-exiting surfaces 1142. Then, the concave light-exiting surface 1142 diffuses the light outward again, thereby increasing the light-exiting area and enhancing the diffusion effect of the light source. This results in uniform brightness of the light-exiting surface 1142 of the entire light guide column 114 and creates the effect of multiple lamp bodies 113 emitting light, resulting in uniform external radiation. This meets the optical requirements of the monitoring module 110. At the same time, by sharing the light guide column 114, the number of light sources is reduced, thus solving the spatial layout problem.

[0041] Recombined Figures 6-8 , Figure 11As shown, in one embodiment of this utility model, the light-emitting surface 1142 has a non-glossy structure. Specifically, the light-emitting surface 1142 can be set as a bubble texture, but it is not limited to this; it can be set as any other structure or texture that can produce a certain light-focusing effect. This structural setting serves two purposes: firstly, it acts as a cover, making the appearance more aesthetically pleasing; secondly, it produces a light-focusing effect, thereby solving the light spot problem, making the light radiation more uniform, and meeting the optical requirements of the device.

[0042] Continue to combine Figures 6-8 , Figure 11 As shown, in one specific embodiment, the light-emitting surface 1142 is provided with a plurality of concave structures 1143, which are arranged in a ring around the center of the light-emitting surface 1142. Specifically, for Figures 6-8 In the embodiment shown, where the light-emitting surface 1142 has an arc-shaped structure, multiple concentric rings of recessed structures 1143 are arranged around the center of the light-emitting surface 1142. That is, each ring of recessed structures 1143 is arranged in a regular pattern. And for... Figure 11 In the embodiment shown where the light-emitting surface 1142 has an elliptical arc structure, multiple concave structures 1143 arranged in an elliptical ring are provided around the center of the light-emitting surface 1142. The concave structures 1143 serve a shielding function, and at the same time, the concave structures 1143 have a light-focusing effect, thereby solving the light spot problem, making the light radiation more uniform, and meeting the optical requirements of the device.

[0043] Understandably, the concave structure 1143 of the light-emitting surface 1142 is not limited to the above-mentioned arrangement, nor is it limited to setting the concave structure 1143; setting other structures is also feasible.

[0044] Continue to combine Figures 6-8 , Figure 11 As shown, in this invention, the light guide post 114 is integrally molded from a transparent material, and the material must be able to transmit infrared light. For example, PC or PMMA material can be selected for molding, but it is not limited to these. In addition, in order to ensure that the light transmittance of the light guide post 114 meets the requirement of being greater than or equal to 90%, and to ensure more uniform light diffusion, about 3% of a diffusing agent can be added to the molding material to further improve the optical uniformity of the light emitted from the light guide post 114.

[0045] The following is combined Figure 4 , Figure 9-10As shown, in one embodiment of this utility model, the lamps 113 of the monitoring module 110 are preferably of different types to meet the optical requirements of the monitoring module 110. In one specific embodiment, the first circuit board 111 is provided with two lamps 113 of different types spaced apart, which are referred to as the first lamp 113 and the second lamp 113 for ease of description. The first lamp 113 is a white LED, and the second lamp 113 is an infrared LED. When the monitoring module 110 is working, the first lamp 113 (white LED) works during the day, and the second lamp 113 (infrared LED) works at night, but this is not limited to this embodiment. Combination Figures 5-8 As shown, in this embodiment, one end face of the light guide post 114 is provided with two light-incident surfaces 1141, and one end face of the light guide post 114 is provided with two light-outceasing surfaces 1142. Both the light-incident surfaces 1141 and 1142 are concave arc-shaped structures in the middle of the light guide post 114 and correspond to each other. After the light guide post 114 is assembled, the two light-incident surfaces 1141 correspond to the first lamp body 113 and the second lamp body 113 respectively and are spaced apart along the light-outceasing direction. Figure 10 As shown, when the first lamp body 113 (white lamp) emits light, the light emitted by it enters the light guide column 114 through its corresponding light-incident surface 1141. After the light-incident surface 1141 diffuses the light, the transmission range of the light entering the entire light guide column 114 is expanded, allowing the light to exit through the two light-out surfaces 1142. Furthermore, the light-out surfaces 1142 diffuse the light again and then disperse it outward, further increasing the light-out area and enhancing the diffusion effect of the light source. This creates the effect of two lamp bodies emitting light, thereby making the brightness of the light-out surfaces 1142 of the entire light guide column 114 uniform, which can meet the optical requirements of the monitoring module 110. At the same time, the first lamp body 113 (white lamp) and the second lamp body 113 (infrared lamp) share a light guide column 114, thereby reducing the number of disassembled parts and solving the space layout problem.

[0046] The following is combined Figure 3-4 , Figure 9 As shown, in one embodiment of this utility model, the light-shielding member 112 is provided with a first receiving hole 1121, the shape of which preferably corresponds to the shape of the light guide post 114. After assembly, one end of the light-shielding member 112 is fixed to the first circuit board 111, and each lamp body 113 is accommodated in the first receiving hole 1121. One end of the light guide post 114 with a light-incident surface 1141 extends into the first receiving hole 1121, and the light guide post 114 and the light-shielding member 112 are sealed together. At the same time, the light-incident surface 1141 and each lamp body 113 are spaced apart along the light-emitting direction. Figure 3 , Figure 9As shown, the light shield 112 is used to prevent light leakage from the bottom of the light guide post 114 to the side, thereby avoiding optical interference between the devices.

[0047] In this embodiment, the light-shielding member 112 is preferably a sealing sleeve, but it is not limited to this, and other materials can also be used for molding.

[0048] Let's combine them again below. Figures 3-4 As shown, in one embodiment of this utility model, the monitoring module 110 further includes a camera assembly 115, a sensor assembly 116, and a second circuit board 117. The second circuit board 117 is spaced apart from the first circuit board 111 and electrically connected to it. Figure 3 As shown. The camera assembly 115 and the sensor assembly 116 are respectively mounted on the second circuit board 117, and the camera assembly 115 passes through the first circuit board 111 and is spaced apart from the light guide post 114. The sensor assembly 116 is spaced apart from the camera assembly 115.

[0049] More specifically, the sensor assembly 116 includes a sensor 1161 and a lampshade 1162. The sensor 1161 is mounted on the second circuit board 117, and the lampshade 1162 is connected to the mounting plate 121 and covers the sensor 1161. Both the sensor 1161 and the lampshade 1162 are conventionally configured in the art.

[0050] Continue to combine Figures 3-4 As shown, in one specific embodiment, the mounting plate 121 has a first through hole 1211, a second through hole 1212, and a third through hole 123 sequentially formed along its height direction. The shape of the first through hole 1211 corresponds to the shape of the light guide post 114, the shape of the second through hole 1212 corresponds to the shape of the camera assembly 115, and the shape of the third through hole 123 is not limited, but its inner diameter is preferably larger than the size of the sensor 1161. When the monitoring module 110 is assembled on the base 120, both the second circuit board 117 and the first circuit board 111 are housed within the base 120, while the light guide post 114 passes through the first through hole 1211 and exits the mounting plate 121, and the camera assembly 115 passes through the second through hole 1212 and exits the mounting plate 121, and both are sealed to the mounting plate 121. Sensor 1161 is mounted corresponding to the third through hole 123. Lamp cover 1162 is sealed to mounting plate 121 and covers the third through hole 123, thereby covering the sensor 1161. The sealing connection between light guide post 114, camera assembly 115, lamp cover 1162 and mounting plate 121 is a conventional method in the art.

[0051] In this specific embodiment, by sharing the light guide pillars 114 and ensuring uniform brightness of the light-emitting surface 1142 of the light guide pillars 114, the optical performance requirements of the device can be met. Therefore, in terms of lamp source layout, it is not necessary to place the lamp sources on the left and right sides of the camera assembly 115 as in the prior art. Instead, the light guide pillars 114 are placed above the camera assembly 115 and corresponding to its center layout, thereby significantly reducing the number of light guide pillars 114, thereby reducing the number of lamp sources, eliminating the stacking layout dilemma, and at the same time meeting the optical requirements.

[0052] In this utility model, the structure and arrangement of the camera assembly 115 and the sensor assembly 116 are conventional and will not be described in detail.

[0053] In summary, the monitoring module 110 of this utility model is provided with a light guide column 114 having a light-transmitting structure. One end face of the light guide column 114 has multiple light-incident surfaces 1141 with an arc-shaped structure, and the other end face of the light guide column 114 forms a light-emitting surface 1142. Each light-incident surface 1141 corresponds to each lamp body 113. In this way, the light emitted by each lamp body 113 enters the light guide column 114 through the light-incident surface 1141 corresponding to that lamp body 113, and passes through the arc-shaped light-incident surface 1141. After the diffusion effect, the light emission angle increases, so the light can pass through the entire light guide 114 and be emitted through the light emission surface 1142, making the brightness of the entire light emission surface 1142 of the light guide 114 uniform. This allows the light emitted through the light guide 114 to meet the optical requirements of the device, thus enabling a scheme in which multiple lamp bodies 113 share a single light guide 114, thereby reducing the number of lamp sources and components. This not only solves the spatial layout problem but also reduces the mutual interference between the optical components.

[0054] Correspondingly, the security monitoring device 100 having the monitoring module 110 of this utility model also has the above-mentioned technical effects.

[0055] The other structures of the security monitoring device 100 involved in this utility model are all conventional structures well known to those skilled in the art, and will not be described in detail here.

[0056] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
