Description

Technical Field

[0001] This application belongs to the field of security monitoring technology, specifically relating to a housing structure and monitoring equipment. Background Technology

[0002] With the development of technology, cameras have been widely used in daily life and industry applications. Outdoor monitoring equipment, in particular, faces harsh working environments, operating under conditions such as rain, snow, sandstorms, humidity, high temperatures, and low temperatures. At the same time, the increasing richness of functions has led to increased internal power consumption in cameras, and the heat dissipation power consumption of components has repeatedly reached new highs.

[0003] The mainstream heat dissipation method for surveillance equipment on the market is air cooling. Specifically, cool air is filtered through a dust filter before entering the camera's interior. A cooling fan then carries away the hot air, completing heat exchange and lowering the temperature of the camera's internal components. However, air cooling requires a cooling fan and a corresponding control module, resulting in higher costs for surveillance equipment. Utility Model Content

[0004] The technical problem this application aims to solve is that existing monitoring equipment with active heat dissipation is costly. To solve this problem, this application provides a housing structure and monitoring equipment that can reduce costs and achieve heat dissipation.

[0005] The technical solution proposed in this application is as follows: A shell structure, comprising: The outer casing has a heat dissipation cavity and an opening communicating with the heat dissipation cavity, and a plurality of first vent holes. The opening is located on the side wall of the outer casing, and the first vent holes are located on the side wall of the outer casing opposite to the side where the opening is located. An inner shell is disposed within the heat dissipation cavity, and the inner shell can form a heat dissipation gap with the inner wall of the heat dissipation cavity. The first vent hole communicates with the heat dissipation gap. The inner shell has an installation cavity and a camera hole communicating with the installation cavity. A camera can be installed in the installation cavity. The camera hole is located on the side of the inner shell facing the opening. A transparent component is sealed to the camera hole of the inner shell to seal the mounting cavity.

[0006] By employing the aforementioned housing structure, the camera is mounted within the inner housing's mounting cavity, and the cavity is sealed with a transparent component, reducing the impact of the external environment on the camera. Furthermore, the inner housing is located within a heat dissipation cavity, and a first vent hole communicating with the heat dissipation gap is provided on the side wall of the outer housing. This prevents direct sunlight from reaching the inner housing while utilizing natural airflow for heat dissipation, eliminating the need for an active cooling structure and effectively reducing costs.

[0007] Furthermore, the bottom wall of the outer casing is provided with a plurality of second vent holes, which are connected to the heat dissipation gap.

[0008] Furthermore, the end of the inner shell containing the camera hole is flush with the end of the outer shell containing the opening; The housing structure also includes a front panel, which is connected to the inner shell and / or the outer shell. The front panel can close the opening and press the transparent part to the inner shell. The front panel also has a light-transmitting hole, which corresponds to the transparent part.

[0009] Furthermore, it also includes a heating coil, which is disposed on the side of the transparent component facing the inner shell, for heating the transparent component.

[0010] Furthermore, the outer surface of the outer casing is provided with a reflective layer.

[0011] Furthermore, the reflective layer is located on the top and side surfaces of the outer casing.

[0012] Furthermore, it also includes shock-absorbing pads; The shock-absorbing pad is disposed on the outer side of the inner shell and abuts against the inner wall of the heat dissipation cavity; or the shock-absorbing pad is disposed on the inner wall of the heat dissipation cavity and abuts against the outer side of the inner shell.

[0013] Furthermore, heat dissipation grooves are provided on the sidewalls and bottom surface of the outer side of the inner shell.

[0014] Furthermore, it also includes a cleaning component, which is at least partially located on the outside of the housing and is used to clean the side of the transparent component opposite to the inner housing.

[0015] A monitoring device includes a camera and the aforementioned housing structure, wherein the camera's image sensor is connected to the image sensor hole of the inner housing.

[0016] In summary, the housing structure and monitoring equipment provided in this application have at least the following advantages: 1. The outer shell is placed outside the inner shell, forming a heat dissipation gap between them. The side walls and bottom of the outer shell are also provided with vents that communicate with the heat dissipation gap. This prevents direct sunlight from hitting the inner shell while creating airflow at the heat dissipation gap to dissipate heat from the inner shell. There is no need to install a cooling fan for active cooling, resulting in lower costs.

[0017] 2. The outer casing has a reflective layer to reduce the absorption of sunlight and further lower the internal temperature, so that the temperature of the top surface of the inner casing is lower than the internal temperature, ensuring that the heat of internal components such as cameras can be dissipated.

[0018] 3. A heating coil is provided at the transparent part, which can heat the transparent part to achieve defogging, and a temperature measuring element is installed inside the heating coil to realize the automatic start and stop of the defogging action.

[0030] On the one hand, this application provides a housing structure that can be applied to monitoring equipment. The monitoring equipment using this housing structure can dissipate heat from the heat-generating components of the monitoring equipment without the need for an active cooling structure with a fan, thereby reducing the cost of the monitoring equipment.

[0031] like Figure 1 and Figure 2 As shown, in one embodiment, the housing structure includes an outer shell 110 and an inner shell 120. The outer shell 110 has a heat dissipation cavity, an opening communicating with the heat dissipation cavity, and a plurality of first vent holes 111. The opening and the first vent holes 111 are all located on the sidewall of the outer shell 110, and the first vent holes 111 are located on the sidewall of the outer shell 110 opposite to the side where the opening is located. For example Figure 3 As shown, except for the side where the opening is located, the other side walls of the outer shell 110 are provided with first vent holes 111. The inner shell 120 is disposed in the heat dissipation cavity, and the inner shell 120 can form a heat dissipation gap 112 with the inner wall of the heat dissipation cavity. The first vent holes 111 are connected to the heat dissipation gap 112.

[0032] Further, please refer to Figure 4 and Figure 5 The inner shell 120 has a mounting cavity 121 and a camera hole 122 communicating with the mounting cavity 121. A camera 200 can be mounted in the mounting cavity 121. The camera hole 122 is located at the end of the inner shell 120 facing the opening, allowing the camera 200 to capture images of the outside through the camera hole 122 and the opening. Furthermore, the shell structure also includes a transparent element 130, which is sealed to the camera hole 122 of the inner shell 120 to seal the mounting cavity 121, preventing external impurities from entering the mounting cavity 121 and affecting the use of the camera 200. At the same time, the transparent element 130 also reduces the impact on the shooting effect of the camera 200.

[0033] It should be noted that if components such as the camera 200 inside the mounting cavity 121 need to be wired, the wiring can be done through a sealed connector to ensure the sealing of the inner shell 120.

[0034] By employing the aforementioned housing structure, the camera 200 is installed within the mounting cavity 121 of the inner housing 120, and the mounting cavity 121 is sealed by the transparent element 130, thereby reducing the impact of the external environment on the camera 200. Furthermore, the inner housing 120 is located within a heat dissipation cavity, and the side wall of the outer housing 110 has a first vent 111 communicating with the heat dissipation gap 112. This prevents direct sunlight from hitting the inner housing 120 while utilizing natural airflow to dissipate heat, eliminating the need for an active cooling structure and effectively reducing costs.

[0035] It is understandable that the aforementioned heat dissipation for the inner shell 120 is actually for dissipating heat from the camera 200 and other heat-generating components within the mounting cavity 121. Additionally, it should be noted that the transparent element 130 is made of glass, and the camera end of the camera 200 is connected to the camera hole 122 of the inner shell 120. The camera end can be open, and the transparent element 130 can also be used to close the camera end of the camera 200.

[0036] Please see Figure 3 In one embodiment, the bottom wall of the outer shell 110 is further provided with a plurality of second vent holes 113, which communicate with the heat dissipation gap 112, thereby further improving gas flow and thus further improving the heat dissipation effect on the inner shell 120. Furthermore, the outer sidewalls and bottom surface of the inner shell 120 are provided with multiple heat dissipation grooves, thereby increasing the surface area of ​​the sidewalls and bottom surface, increasing the heat dissipation area of ​​the inner shell 120, and improving the heat dissipation effect of the inner shell 120.

[0037] In practical applications, the outer casing 110 includes an upper casing 114 and a bottom plate 115. The bottom of the upper casing 114 is connected to the bottom plate 115 to form the aforementioned heat dissipation cavity. A first vent 111 is provided on the side wall of the upper casing 114, and a second vent 113 is provided on the bottom plate 115. Specifically... Figure 3 In the middle, a connecting protrusion is formed inward at the bottom of the upper housing 114, and the bottom plate 115 is connected to the connecting protrusion.

[0038] In one embodiment, a reflective layer is provided on the outer surface of the housing 110, which can be formed by spraying reflective paint. By providing a reflective layer, most of the sunlight is reflected away, reducing the heat from the sunlight and preventing the heating element in the inner housing 120 from overheating. In practical applications, the reflective layer is located on the top and sides of the housing 110.

[0039] Please see Figure 1In one embodiment, the housing structure further includes a shock-absorbing pad 140. The shock-absorbing pad 140 is disposed between the outer shell 110 and the inner shell 120, specifically within the heat dissipation gap 112, to ensure a heat dissipation gap 112 is formed between the outer shell 110 and the inner shell 120 while preventing collision between the inner shell 120 and the outer shell 110 when the housing structure vibrates. It should be noted that the inner shell 120 can be fixedly connected to the outer shell 110 by bolts. During bolt tightening, the outer shell 110 and the inner shell 120 clamp the shock-absorbing pad 140, thereby securing the outer shell 110 and the inner shell 120 together. Optionally, the shock-absorbing pad 140 can be made of rubber and can be disposed on the outer side of the inner shell 120, abutting against the inner wall of the heat dissipation cavity; alternatively, it can be disposed on the inner wall of the heat dissipation cavity, abutting against the outer side of the inner shell 120. Furthermore, the shock-absorbing pad 140 can be first glued to the inner shell 120 or the outer shell 110.

[0040] Please see Figure 4 and Figure 5 In one embodiment, the end of the inner shell 120 containing the camera hole 122 is flush with the end of the outer shell 110 containing the opening. The shell structure also includes a front panel 150, which is connected to the inner shell 120 and / or the outer shell 110 (the following description uses the example of the front panel 150 being connected to both the inner shell 120 and the outer shell 110). The front panel 150 can close the opening, i.e., the front panel 150 is connected to both the end of the inner shell 120 containing the camera hole 122 and the end of the outer shell 110 containing the opening. Furthermore, when the front panel 150 is connected to both the inner shell 120 and the outer shell 110, the front panel 150 can also press and fix the transparent element 130 to the inner shell 120.

[0041] Furthermore, the front panel 150 also has a light-transmitting hole 151, which corresponds to the transparent component 130, allowing the camera 200 to capture images of the outside world through the transparent component 130 and the light-transmitting hole 151. It should be noted that the diameter of the light-transmitting hole 151 is slightly smaller than that of the transparent component 130, so that the edge of the light-transmitting hole 151 abuts against the edge of the transparent component 130, pressing and fixing the transparent component 130 to the camera hole 122 of the inner shell 120. Additionally, the edge of the light-transmitting hole 151 abutting against the transparent component 130 is chamfered, so that while pressing and fixing the transparent component 130, the side of the transparent component 130 away from the camera 200 is flush with the side of the front panel 150 away from the inner shell 120.

[0042] In one embodiment, the housing structure further includes a heating coil 160. The heating coil 160 is disposed on the side of the transparent element 130 facing the inner housing 120, i.e., the side facing the camera 200, and is used to heat the transparent element 130 to defog it when fogging occurs. Additionally, a temperature sensor may be built into the heating coil 160 to automatically start and stop the defogging operation.

[0043] In one embodiment, the housing structure further includes a cleaning assembly 170. The cleaning assembly 170 is at least partially located on the outside of the housing 110, and is used to clean the side of the transparent component 130 facing away from the inner housing 120, i.e., away from the camera 200, to prevent contamination of the outer surface of the transparent component 130 from affecting the camera 200's recording. Specifically, the cleaning assembly 170 may include a cleaning drive and a cleaning brush. The cleaning drive is disposed within the mounting cavity 121, and its drive end extends to the side of the front panel 150 facing away from the inner housing 120. The cleaning brush is connected to the drive end and reciprocates under the drive of the drive, thus cleaning the transparent component 130 during the oscillation. It is understood that the outer surface of the transparent component 130 is flush with the surface of the front panel 150 facing away from the inner housing 120, ensuring that the cleaning brush can clean the outer surface of the transparent component 130 during its oscillation.

[0044] It should be noted that the driving end is a drive shaft, which passes through the inner shell 120 and the front panel 150. A shaft seal structure can be provided between the drive shaft and the inner shell 120 or between the drive shaft and the front panel 150 to ensure the sealing of the mounting cavity 121. In addition, in this embodiment, the cleaning component 170 is added to clean the transparent part 130, which is different from the cooling fan used for active heat dissipation mentioned above. That is to say, with the cleaning component 170, the cost of using a cooling fan for active heat dissipation is higher than the cost of the shell structure provided in this application.

[0045] In one embodiment, a drying module is also provided inside the mounting cavity 121. The drying module can absorb moisture inside the mounting cavity 121, keeping the mounting cavity 121 dry and extending the service life of the components inside the mounting cavity 121. In practical applications, the drying module may include a packaging box and a desiccant. The packaging box is disposed inside the mounting cavity 121 and has multiple drying holes. The desiccant is disposed inside the packaging box.

[0046] Based on the aforementioned housing structure, this application also provides a monitoring device, which includes the housing structure described in the above embodiments and a camera 200. The camera 200 is installed in the mounting cavity 121, and its camera end is connected to the camera hole 122 of the inner housing 120. This connection can be achieved through glue or other means. Furthermore, in this embodiment, there are two cameras 200, corresponding to two camera holes 122 in the inner housing 120 and two light-transmitting holes 151 in the front panel 150.

[0047] To demonstrate the advantages of the housing structure and monitoring equipment provided in this application compared with the prior art, embodiments and comparative examples are provided herein for illustration; The monitoring device in this embodiment adopts the structure described in this application. The monitoring device in the comparative example adopts a structure similar in shape to the inner shell 120 in the above embodiment but without the outer shell 110. Furthermore, the outer shell 110 and inner shell 120 in this embodiment, as well as the shell of the monitoring device in the comparative example, are all made of aluminum alloy. Modeling and simulation were performed using Flotherm XT software. The simulation conditions were: location in Beijing (39.9°N, 116.4°E), time of noon in summer, ambient temperature of 55°C, power settings for the two cameras 200 in the monitoring device set to 20W and 5W respectively, and power setting for the main control board set to 15W. Additionally, the radiation absorption rate of the aluminum alloy surface can be set according to requirements; for example, the absorption rate of an untreated surface is 0.2~0.4, the absorption rate of a black anodized surface is 0.8~0.9, the absorption rate of a dark-coated surface is 0.8~0.95, and the absorption rate of a polished surface is 0.1~0.2.

[0048] In the embodiment, the initial temperature is 55°C, the final internal temperature is 68.892°C, and the temperature rises by 13.892°C. The final temperature of the outer top surface of the inner shell 120 is 67.221°C, and the temperature rises by 12.221°C. In the comparative example, the initial temperature is 55°C, the final internal temperature is 85.857°C, and the temperature rises by 30.857°C. The temperature of the outer top surface of the equipment housing is 92.445°C, and the temperature rises by 37.445°C.

[0049] In summary, the housing structure and monitoring equipment provided in this application have at least the following advantages: 1. The outer shell 110 covers the outer side of the inner shell 120 and forms a heat dissipation gap 112 between them. The side wall and bottom surface of the outer shell 110 are also provided with ventilation holes that communicate with the heat dissipation gap 112. This allows for airflow at the heat dissipation gap 112 to dissipate heat from the inner shell 120 while preventing direct sunlight from shining on it. This eliminates the need for a cooling fan for active cooling and reduces costs.

[0050] 2. The outer casing 110 is equipped with a reflective layer to reduce the absorption of sunlight and further reduce the internal temperature, so that the temperature of the top surface of the inner casing 120 is lower than the internal temperature, ensuring that the heat of internal components such as the camera 200 is dissipated.

[0051] 3. A heating coil 160 is provided at the transparent part 130, which can heat the transparent part 130 to achieve defogging, and a temperature measuring element is provided inside the heating coil 160 to realize the automatic start and stop of the defogging action.

[0052] 4. The cleaning component 170 can scrub the outer surface of the transparent part 130, improving the reliability of use.

[0053] 5. The inner shell 120 has heat dissipation grooves on its side walls and bottom surface, which can further improve the heat dissipation effect.

[0054] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
