Description

Technical Field

[0001] This application relates to the field of camera technology, and in particular to a metal housing for a surveillance camera. Background Technology

[0002] In recent years, with the rapid development of my country's economy, people's demand for security in modern society has been increasing, and the security industry has emerged as a result. The three major products of security equipment include surveillance cameras, access control and burglar alarm equipment, among which surveillance cameras are still the most important component.

[0003] Surveillance cameras are semiconductor imaging devices with advantages such as high sensitivity, resistance to strong light, low distortion, small size, long lifespan, and vibration resistance. However, cameras are susceptible to the effects of low temperatures. In regions like Xinjiang, Tibet, and Qinghai in my country, the temperature difference between day and night is extremely large in summer, often exceeding 20°C. Low temperatures can affect surveillance cameras, potentially impacting their efficiency, slowing down recording speed, affecting image quality, and even completely damaging the camera.

[0004] In related technologies, protective housings are typically used to reduce the impact of temperature changes on surveillance cameras, thereby ensuring their normal operation. However, the surveillance cameras in these technologies are difficult to adapt to the temperature differences between day and night in some parts of my country during the summer, which seriously affects their working efficiency. Summary of the Invention

[0005] To address the problem that surveillance cameras in related technologies are unable to adapt to the changes in day-night temperature differences in some parts of my country during summer, which seriously affects the working efficiency of surveillance cameras, this application provides a metal casing for a surveillance camera.

[0006] The technical solution for a metal casing of a surveillance camera provided in this application is as follows: A metal housing for a surveillance camera, for mounting outside the camera body, comprising: Mounting base, one end of which is fixedly connected to the camera body, and the other end of which is detachably connected to a metal wing plate. The metal wing plate is made of flexible metal material, and a heat insulation layer is provided on the side of the metal wing plate close to the camera body. The heat insulation layer is used to keep the camera body warm. A connector, one end of which is fixedly connected to the camera body, and the other end of which is fixedly connected to the end of the metal wing plate near the camera body. Two connectors are provided, and the two connectors are symmetrically arranged along the central axis of the long side of the camera body. The two connectors symmetrically arranged along the central axis of the long side of the camera body form a support group.

[0007] By adopting the above technical solution, the mounting base is installed outside the camera body. After the mounting base is installed, the metal wing plate is also in place. At this time, one end of the connector is fixedly connected to the camera body, and the other end of the connector is connected to the metal wing plate. The support group composed of the two connectors can effectively support the metal wing plate. At this time, the support group plays a role in tying and supporting the metal wing plate. The side of the metal wing plate close to the camera body is provided with a heat insulation layer. The heat insulation layer provides a heat insulation effect for the camera body, so that the camera can work normally even in low temperature environments. This application solves to a certain extent the problem in the related technology that the surveillance camera is difficult to adapt to the changes in day and night temperature in some parts of my country in summer, which seriously affects the working efficiency of the surveillance camera.

[0008] Optionally, multiple sets of support groups are provided, and the multiple sets of support groups are evenly distributed along the long side of the camera body.

[0009] By adopting the above technical solution, the support group is set into multiple groups, which are evenly distributed along the long side of the camera body. This allows the metal wing plate to be more stably wrapped around the camera body, and the insulation layer can better insulate the camera body, thereby improving the working stability of the camera body in low-temperature environments to a certain extent.

[0010] Optionally, the connector is a shape memory metal component, which is bent and can straighten from a bent shape due to temperature.

[0011] By adopting the above technical solution, the connector is made of shape memory metal, and the shape memory metal is made to be curved. This allows the shape memory metal to bend and straighten when the camera body is located in a region of my country with large temperature differences between day and night. When the temperature is high during the day, the shape memory metal is in a straight state, and the metal wing plate is in an unfolded state, which can effectively dissipate heat from the camera body. When the temperature is low at night, the shape memory metal will slowly return to a curved state. At this time, the curved shape memory metal will drive the metal wing plate to retract, that is, drive the metal wing plate to wrap around the camera body. This allows the camera body to be protected by the heat insulation layer at low temperatures at night, which reduces the possibility of the camera body becoming inefficient or damaged due to temperature changes to a certain extent.

[0012] Optionally, the plane formed when the shape memory metal part is bent is parallel to the lens plane of the camera body.

[0013] By adopting the above technical solution, when the plane formed by the bending shape of the memory metal part is parallel to the lens of the camera body, the metal wing can be expanded to the maximum extent when the memory metal part changes from a bent state to a straight state, thereby enabling the camera body to dissipate heat as efficiently as possible during the day.

[0014] Optionally, a solar photovoltaic panel is provided on the outer surface of the metal wing plate.

[0015] By adopting the above technical solution, a solar photovoltaic panel is set on the outer surface of the metal wing plate, so that when the metal wing plate is in the unfolded state during the day, the metal wing plate can also collect electrical energy, and the stored electricity can be used as the power energy of the camera body.

[0016] Optionally, a heat preservation base is detachably connected to the side wall of the camera body, and the heat preservation base is used to keep the end of the camera body away from the metal wing plate warm.

[0017] By adopting the above technical solution, the setting of the heat preservation base ensures that the end of the camera body away from the metal wing plate can also be effectively insulated.

[0018] Optionally, the heat preservation base is provided with a refractive inclined surface, which extends from the heat preservation base in a direction away from the camera body, and a lens is provided on the refractive inclined surface.

[0019] By adopting the above technical solution, the mirror can effectively reflect sunlight onto the side of the metal wing panel closest to the camera body during the day, further enhancing the photovoltaic panel's ability to convert solar energy into electrical energy.

[0020] Optionally, a non-powered fan is rotatably connected to the end of the camera body away from the mirror surface. The non-powered fan is used to dissipate heat and clean dust from the camera body.

[0021] By adopting the above technical solution, the fanless design can effectively dissipate heat and clean dust from the camera body, and can also immediately clean dust from the mirror surface. This allows the mirror to effectively reflect sunlight onto the lower surface of the metal wing plate during the day, thereby further improving the photovoltaic panel's ability to convert solar energy into electricity.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By using a mounting base, metal wing plate, and connectors, in regions of my country where day and night temperatures vary greatly in summer, the mounting base can be installed on the outside of the camera body first. After the mounting base is in place, the metal wing plate will also be in place. At this time, one end of the connector is fixedly connected to the camera body, and the other end of the connector is connected to the metal wing plate. The support group composed of the two connectors can effectively support the metal wing plate. The support group plays a role in tying and supporting the metal wing plate. An insulation layer is provided on the side of the metal wing plate close to the camera body. The insulation layer provides insulation for the camera body, so that the camera can work normally even in low-temperature environments. This application solves to some extent the problem in related technologies that surveillance cameras are difficult to adapt to the changes in day and night temperature in some parts of my country in summer, which seriously affects the working efficiency of surveillance cameras. 2. By using a memory metal connector, the camera body can bend and straighten when located in regions with large day-night temperature differences. During the day when the temperature is high, the memory metal connector is straight, and the metal wing plate is unfolded, allowing the camera body to effectively dissipate heat. At night when the temperature is low, the memory metal connector slowly returns to its bent shape. This bending motion causes the metal wing plate to retract, effectively enveloping the camera body. This provides insulation protection for the camera body at low nighttime temperatures, reducing the likelihood of inefficiency or damage caused by temperature fluctuations. 3. By setting solar photovoltaic panels on the outer surface of the metal wing, the metal wing is in the deployed state during the day. At this time, the metal wing can also collect electrical energy, and the stored electricity can be used as the power source for the camera body. Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0028] This application discloses a metal casing for a surveillance camera.

[0029] It should be noted that, in the description of this invention, the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this invention.

[0030] Reference Figure 1 A metal casing for a surveillance camera, used for mounting on the outside of the camera body 1, includes a mounting base 2 and a connector 4. One end of the mounting base 2 is fixedly connected to the camera body 1, and the other end of the mounting base 2 is detachably connected to a metal wing plate 3. The metal wing plate 3 is made of flexible metal material, and a heat insulation layer is provided on the side of the metal wing plate 3 near the camera body 1 to insulate the camera body 1. One end of the connector 4 is fixedly connected to the camera body 1, and the other end of the connector 4 is fixedly connected to the end of the metal wing plate 3 near the camera body 1. There are two connectors 4, which are symmetrically arranged along the central axis of the long side of the camera body 1. The two connectors 4 arranged symmetrically along the central axis of the long side of the camera body 1 form a support group 5.

[0031] In this embodiment, the main function of the mounting base 2 is to connect the middle part of the metal wing plate 3. The mounting base 2 can be welded to the camera body 1. In other embodiments, the mounting base 2 can also be connected to the camera body 1 using other mechanical connection methods.

[0032] In this embodiment, the mounting base 2 and the metal wing plate 3 are detachably connected by a plug-in method. Since this plug-in method is quite conventional, it is not shown in the accompanying drawings. In other embodiments, the mounting base and the metal wing plate 3 can also be installed and removed by means of mutual attraction using magnets.

[0033] After mounting the base 2 on the outside of the camera body 1, the metal wing plate 3 is also in place. At this time, one end of the connector 4 is fixedly connected to the camera body 1, and the other end of the connector 4 is connected to the metal wing plate 3. The support group 5 composed of the two connectors 4 can effectively support the metal wing plate 3. At this time, the support group 5 plays a role in supporting the metal wing plate 3. The side of the metal wing plate 3 close to the camera body 1 is provided with a heat insulation layer. The heat insulation layer provides a heat insulation effect for the camera body 1, so that the camera can work normally even when it is in a low temperature environment. This application solves to a certain extent the problem that the surveillance camera in the related technology is difficult to adapt to the changes in day and night temperature in some parts of my country in summer, which seriously affects the working efficiency of the surveillance camera.

[0034] It should be noted that in this embodiment, the metal wing plate 3 is a flexible composite metal plate, and the insulation layer is located inside the metal plate. The metal wing plate 3 needs to be manufactured before installation.

[0035] Referring to the figure, a solar photovoltaic panel is provided on the outer surface of the metal wing plate 3.

[0036] A solar photovoltaic panel is installed on the outer surface of the metal wing plate 3, so that when the metal wing plate 3 is in the unfolded state during the day, the metal wing plate 3 can also collect electrical energy, and the stored electricity can be used as the power energy of the camera body 1.

[0037] It should be noted that, in the accompanying drawings of the embodiments of this application, since setting up solar photovoltaic panels and installing corresponding batteries for storing electrical energy are conventional technical means in the field, and only adaptive changes need to be made to the metal wing plate 3 and the camera body 1 to achieve reasonable and effective installation, the solar photovoltaic panels and batteries for storing electrical energy are not shown in the accompanying drawings of the embodiments of this application.

[0038] In this embodiment, the metal wing plate 3 is not completely attached to the camera body 1. However, since the metal wing plate 3 has an insulation layer inside, it can still insulate the camera body 1 even without direct contact. In other embodiments, the insulation layer can be installed on the lower surface of the metal wing plate 3, and the insulation layer is made of a flexible material, such as sponge. When the connector 4 is connected to the camera body 1, the insulation layer is attached to the camera body 1.

[0039] Referring to the figures, in this embodiment of the application, multiple sets of support groups 5 are provided, and the multiple sets of support groups 5 are evenly distributed along the long side of the camera body 1.

[0040] The support group 5 is set into multiple groups, and the multiple support groups 5 are evenly distributed along the long side of the camera body 1, so that the metal wing plate 3 can be more stably wrapped around the camera body 1. In other words, the heat insulation layer can better insulate the camera body 1, thereby improving the working stability of the camera body 1 in low temperature environment to a certain extent.

[0041] In other embodiments, the support group 5 can be set as one group or as multiple groups that are unevenly distributed, which is also feasible.

[0042] Referring to the figure, connector 4 is a shape memory metal component, which is bent and can straighten under temperature influence. Shape memory metal is a special metallic material that undergoes plastic deformation within a certain temperature range and then recovers its original macroscopic shape within another temperature range; it first appeared in the 1970s. Therefore, using shape memory metal as connector 4 in this embodiment is effective.

[0043] The connector 4 is made of shape memory metal and is curved. This allows the shape memory metal to bend and straighten when the camera body 1 is located in a region with large temperature differences between day and night. During the day when the temperature is high, the shape memory metal is in a straight state, and the metal wing plate 3 is in an unfolded state, which allows the camera body 1 to effectively dissipate heat. At night when the temperature is low, the shape memory metal will slowly return to a curved state. At this time, the curved shape memory metal will drive the metal wing plate 3 to retract, which will cause the metal wing plate 3 to wrap around the camera body 1. This allows the camera body 1 to be protected by the insulation layer at low temperatures at night, which reduces the possibility of the camera body 1 becoming inefficient or damaged due to temperature changes.

[0044] Referring to the figure, the plane formed when the shape memory metal part is bent is parallel to the lens plane of the camera body 1. In this configuration, the shape memory metal can maximize the expansion of the metal wings.

[0045] When the plane formed by the bent shape of the memory metal part is parallel to the lens of the camera body 1, the metal wing plate 3 can be expanded to the maximum extent when the memory metal part changes from a bent state to a straight state, so that the camera body 1 can dissipate heat as efficiently as possible during the day.

[0046] In other embodiments, the connector 4 can be configured as an electric telescopic rod. If the connector 4 is configured as an electric telescopic rod, the operator needs to extend and retract the electric telescopic rod at regular intervals, or a corresponding program can be set for the electric telescopic rod to extend and retract at regular intervals.

[0047] Referring to the figure, a heat preservation base 6 is detachably connected to the side wall of the camera body 1. The heat preservation base 6 is used to keep the end of the camera body 1 away from the metal wing plate 3 warm.

[0048] The heat-insulating base 6 ensures that the end of the camera body 1 away from the metal wing plate 3 can also be effectively insulated.

[0049] Referring to the figures, in this embodiment of the application, a refractive inclined surface 7 is provided on the heat preservation base 6. The refractive inclined surface 7 extends from the heat preservation base 6 in a direction away from the camera body 1, and a lens 8 is provided on the refractive inclined surface 7. In other embodiments, it is also possible to configure the refractive inclined surface 7 into other shapes that can refract sunlight, such as a trapezoidal shape.

[0050] The mirror design allows sunlight to be effectively reflected onto the side of the metal wing panel 3 closest to the camera body 1 during the day, further enhancing the photovoltaic panel's ability to convert solar energy into electricity.

[0051] Referring to the figure, a non-powered fan 9 is rotatably connected to the end of the camera body 1 away from the mirror surface. The non-powered fan 9 is used for heat dissipation and dust removal of the camera body 1. In other embodiments, it is also a preferred embodiment of this application to adaptively install a fan powered by solar energy converted from solar photovoltaic panels.

[0052] The non-powered fan 9 serves two purposes: firstly, it effectively dissipates heat and cleans dust from the camera body 1; secondly, it immediately cleans dust from the mirror surface, allowing the mirror to effectively reflect sunlight onto the lower surface of the metal wing plate 3 during the day, thereby further improving the photovoltaic panel's ability to convert solar energy into electrical energy.

[0053] The implementation principle of the metal casing of a surveillance camera in this application embodiment is as follows: When installing a camera in areas of my country with large temperature differences between day and night, the mounting base 2 is installed on the outside of the camera body 1. After the mounting base 2 is installed, the metal wing plate 3 is also in place. At this time, one end of the connector 4 is fixedly connected to the camera body 1, and the other end of the connector 4 is connected to the metal wing plate 3. The support group 5 composed of the two connectors 4 can effectively support the metal wing plate 3. At this time, the support group 5 plays a role in tying and supporting the metal wing plate 3. The side of the metal wing plate 3 close to the camera body 1 is provided with a heat insulation layer. The heat insulation layer provides a heat insulation effect for the camera body 1, so that the camera can work normally even in a low temperature environment. This application solves to a certain extent the problem that surveillance cameras in related technologies are difficult to adapt to the changes in temperature differences between day and night in some parts of my country in summer, which seriously affects the working efficiency of surveillance cameras.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
