Description

Technical Field

[0001] The invention relates to the technical field of cameras, in particular to a heat dissipation aluminum plate for a rear shell of a camera. Background Art

[0002] There are many types of cameras, and their basic working principles are the same: converting optical image signals into electrical signals for storage or transmission. When we shoot an object, the light reflected from the object is collected by the camera lens and focused on the light-receiving surface of the camera device (such as the target surface of the camera tube). The camera device then converts the light into electrical energy, which is a "video signal". The photoelectric signal is very weak and needs to be amplified by a pre-amplifier circuit, and then processed and adjusted by various circuits. The final standard signal can be sent to a recording medium such as a video recorder for recording, or transmitted through a transmission system or sent to a monitor for display.

[0003] During long-term use of the camera, its internal electronic components will generate a lot of heat. If the heat cannot be dissipated quickly, it will affect the normal operation of the camera. Some cameras will have a cooling fan installed inside to help the camera dissipate heat quickly. However, when the cooling fan needs to be maintained or replaced during use, a large number of screws need to be removed, which is inconvenient and affects the efficiency of maintenance and replacement.

[0004] In order to solve the above technical problems, many related patents have been proposed in the prior art, such as a Chinese patent with application number 2019222232151.0, authorization announcement number CN210839767U, and name of a high-efficiency heat dissipation camera. The above patent discloses a high-efficiency heat dissipation camera, including a camera body, an opening is opened on the side of the camera body away from the camera head, and two positioning plates are symmetrically fixedly connected at the opening, a same heat dissipation box is clamped between the two positioning plates, and the side of the heat dissipation box facing the camera body is an opening structure, and the heat dissipation box is equidistantly opened on the two side walls opposite to the two positioning plates of the heat dissipation box, and a thrust spring is arranged in the cylindrical groove, one end of the thrust spring is fixedly connected to the inner wall of the cylindrical groove, and the other end of the thrust spring is fixedly connected to a limit rod, and a limit hole corresponding to the limit rod is opened on the side wall of the positioning plate, and a heat dissipation fan is fixedly arranged on the inner wall of the heat dissipation box, and a plurality of heat dissipation rods are evenly fixedly connected to the heating area in the camera body, and a plurality of heat dissipation rods are fixedly connected to the same heat dissipation plate at one end away from the camera body.

[0005] In the above patent, the camera body can quickly conduct the heat generated by the heating area in the camera body out of the camera body through the heat dissipation rod and the heat dissipation plate, so as to dissipate the heat of the camera body well. When the heat dissipation fan is started, the heat dissipation fan further dissipates the heat in the camera body quickly. As is known, heat dissipation holes are usually opened on the camera housing in the prior art to facilitate the heat dissipation operation of the camera.

[0006] However, the heat dissipation holes in the prior art cannot adjust the state of the heat dissipation holes according to work needs. For example, when the camera is performing a video recording operation, the heat dissipation holes are in an on state. When the camera is not needed, the heat dissipation holes need to be closed to prevent dust and impurities from the outside from entering the camera and affecting the normal use of the camera. There are certain deficiencies. Summary of the invention

[0014] Furthermore, an adjustment mechanism is also provided on the shell. When the shell is mounted on the camera body, the state of the shielding portion is adjusted by the adjustment mechanism to realize the opening and closing of the heat dissipation hole.

[0015] Furthermore, the adjustment mechanism is slidably connected to an adjustment block on the mounting tube, an adjustment screw is rotatably connected to the shell, a threaded groove is provided on the adjustment block, and the adjustment screw is rotatably connected to the adjustment block through the threaded groove; when the adjustment screw rotates, the adjustment block is driven to slide inside the mounting tube to reduce the distance between the adjustment block and the limit rod.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: the heat dissipation aluminum plate of the camera rear shell, through the cooperation between the shell, the heat dissipation holes, the shielding parts, the trigger mechanism, etc., when the heat dissipation holes need to be used for heat dissipation, the shell is first installed on the camera body, and during the installation of the shell, the driving plate is driven to slide through the trigger mechanism. When the driving plate slides, since the multiple groups of shielding parts are fixedly connected to the driving plate, when the driving plate slides, it will drive the multiple groups of shielding parts to slide inside the heat dissipation holes, so that the heat dissipation state can be opened to facilitate the heat dissipation operation of the camera body, thereby greatly improving the heat dissipation efficiency of the camera body.

[0019] When the housing is not removed from the camera body and the heat dissipation hole needs to be closed, the adjusting screw is driven to rotate.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-11 The present invention provides a technical solution: a camera rear shell heat dissipation aluminum plate, comprising a camera body 1, a shell 2 is installed on the camera body 1, a plurality of heat dissipation holes 3 are provided on the shell 2, each heat dissipation hole 3 is slidably connected with a shielding portion 5; the plurality of shielding portions 5 are fixedly connected by a driving plate 4; the shell 2 is provided with a trigger mechanism, and the trigger mechanism is transmission-connected with the driving plate 4; when the shell 2 is installed on the camera body 1, the driving plate 4 is driven to slide inside the shell 2 by the trigger mechanism, so that the heat dissipation holes 3 are in a conducting state.

[0035] Specifically, the heat dissipation aluminum plate on the back shell of the camera includes a camera body 1. There are many types of cameras, and the basic principle of its brand cameras is the same: converting optical image signals into electrical signals for storage or transmission. When we shoot an object, the light reflected from the object is collected by the camera lens, so that it is focused on the light-receiving surface of the camera device (such as the target surface of the camera tube), and then the camera device converts the light into electrical energy, that is, a "video signal" is obtained. The photoelectric signal is very weak and needs to be amplified by a pre-amplifier circuit, and then processed and adjusted by various circuits. The standard signal finally obtained can be sent to a recording medium such as a video recorder for recording, or transmitted through a transmission system or sent to a monitor for display. A shell 2 is installed on the camera body 1. Specifically, the shell 2 is made of aluminum. Aluminum is preferred because it is corrosion-resistant. Aluminum can naturally form a dense aluminum oxide protective film in the air, which gives it good corrosion resistance and increases the service life of the camera body 1. At the same time, aluminum has good thermal conductivity and electrical conductivity, and can better dissipate heat inside the camera body 1. Furthermore, aluminum has good plasticity and ductility, and can be easily processed into products of various shapes and specifications by rolling, extrusion, stretching, casting, etc., so as to be better processed.

[0036] There are multiple groups of heat dissipation holes 3 on the shell 2. By providing multiple groups of heat dissipation holes 3, the camera body 1 can be better cooled. Each heat dissipation hole 3 is slidably connected with a shielding part 5. When the inside of the camera body 1 needs to be cooled, the shielding part 5 is opened. When heat dissipation is not required, the shielding part 5 needs to close the heat dissipation hole 3 to prevent external dust and impurities from entering the inside of the camera body 1, thereby further improving the service life of the camera body 1 and achieving better use effect. At the same time, multiple groups of shielding parts 5 are fixedly connected by a driving plate 4. Therefore, when the driving plate 4 slides, it will drive the multiple groups of shielding parts 5 to adjust the state of the heat dissipation holes 3, greatly improving the practicality of the camera body 1.

[0037] As is known, a snap-fit ​​mechanism is usually provided between the housing 2 and the camera body 1. When the housing 2 is installed on the camera body 1, the housing 2 is fixed on the camera body 1 by the snap-fit ​​mechanism, thereby improving the stability of the housing 2 during installation and meeting the working requirements. A trigger mechanism is provided in the housing 2, and the trigger mechanism is in transmission connection with the drive plate 4. The state of the drive plate 4 can be adjusted by the trigger mechanism, and then the state of the shielding portion 5 can be adjusted. Specifically, in actual use, when the housing 2 is installed on the camera body 1, the drive plate 4 is driven to slide inside the housing 2 by the trigger mechanism, so that the heat dissipation hole 3 is in a conducting state. When it is necessary to use the heat dissipation holes 3 for heat dissipation, the shell 2 is first installed on the camera body 1. During the installation of the shell 2, the driving plate 4 is driven to slide by the trigger mechanism. When the driving plate 4 slides, since the multiple groups of shielding parts 5 are fixedly connected to the driving plate 4, when the driving plate 4 slides, it will drive the multiple groups of shielding parts 5 to slide inside the heat dissipation holes 3, so that the heat dissipation state can be opened to facilitate the heat dissipation operation of the camera body 1, thereby greatly improving the heat dissipation efficiency of the camera body 1 and achieving better use effect.

[0038] In the embodiment provided by the present invention, the trigger mechanism includes a mounting tube 19, a trigger tube 11 is slidably connected to the mounting tube 19, a pressure plate 7 is fixedly connected to the trigger tube 11, a wedge plate 8 is fixedly connected to the pressure plate 7, a wedge groove is provided at the bottom of the wedge plate 8; and an inclined groove is provided on the driving plate 4, when the housing 2 is mounted on the camera body 1, the wedge groove abuts against the inclined groove, so as to drive the driving plate 4 to drive the shielding part 5 to slide. When the housing 2 is mounted on the camera body 1, the pressure plate 7 is driven to slide by the trigger tube 11, and the pressure plate 7 drives multiple groups of wedge plates 8 to slide during the sliding stroke, and when the housing 2 is mounted on the camera body 1, the wedge groove abuts against the inclined groove, so that when the driving plate 4 slides, it drives multiple groups of shielding parts 5 to slide inside the heat dissipation hole 3, so that the heat dissipation state can be opened to facilitate the heat dissipation operation of the camera body 1.

[0039] In the embodiment provided by the present invention, a limiting rod 14 is fixedly connected to the bottom of the pressure plate 7, a limiting groove 15 adapted to the limiting rod 14 is opened inside the mounting cylinder 19, and the limiting rod 14 is slidably connected to the limiting groove 15, thereby further improving the stability of the pressure plate 7 when sliding.

[0040] In the embodiment provided by the present invention, a compression spring 16 is further arranged between the pressure plate 7 and the limiting groove 15. The elastic force of the compression spring 16 drives the pressure plate 7 away from the mounting tube 19. When there is no external force to compress the pressure plate 7, the compression spring 16 drives the pressure plate 7 to slide in the opposite direction during the process of restoring the elastic deformation.

[0041] In the embodiment provided by the present invention, a trigger portion 12 is further provided on the trigger tube 11, and the trigger portion 12 includes a trigger plate, a connecting rod is fixedly connected to the trigger plate, a vertical groove is provided inside the trigger tube 11, the connecting rod is slidably connected inside the vertical groove, and a positioning spring 13 is provided between the connecting rod and the vertical groove, and the elastic force of the positioning spring 13 drives the trigger plate away from the trigger tube 11. By providing the trigger portion 12, the application range of the housing 2 can be further improved.

[0042] In the embodiment provided by the present invention, the housing 2 is further provided with an adjustment mechanism, and when the housing 2 is mounted on the camera body 1, the state of the shielding portion 5 is adjusted by the adjustment mechanism to realize the opening and closing of the heat dissipation hole 3. That is, during use, when the housing 2 is not removed from the camera body 1 and the heat dissipation hole 3 needs to be closed, the shielding portion 5 inside the heat dissipation hole 3 is adjusted by using the adjustment mechanism to realize the closing of the heat dissipation hole 3 and protect the camera body 1.

[0043] In the embodiment provided by the present invention, the adjustment mechanism is slidably connected to the adjustment block 17 on the mounting tube 19, and the housing 2 is rotatably connected to an adjustment screw 18, and the adjustment block 17 is provided with a thread groove, and the adjustment screw 18 is rotatably connected to the adjustment block 17 through the thread groove; when the adjustment screw 18 rotates, the adjustment block 17 is driven to slide inside the mounting tube 19 to reduce the distance between the adjustment block 17 and the limit rod 14. Therefore, during use, when the housing 2 is not disassembled from the camera body 1 and the heat dissipation hole 3 needs to be closed, the adjustment screw 18 is driven to rotate. Since the adjustment block 17 is threadedly connected to the adjustment screw 18, when the adjustment screw 18 rotates, the adjustment block 17 is driven to slide inside the mounting tube 19. When the adjustment block 17 slides to abut against the limit rod 14 and continues to drive the adjustment block 17 to squeeze the limit rod 14, the limit rod 14 is squeezed at this moment and the positioning spring 13 is squeezed. At this moment, the pressure plate 7 will slide away from the driving plate 4 under the pressure of the limiting rod 14. At this moment, the driving plate 4 will drive the shielding part 5 to close the heat dissipation hole 3 during the process of restoring its elastic deformation, thereby protecting the camera body 1 and achieving better use effect.

Therefore, when the pressure plate 7 is away from the driving plate 4, that is, when the pressure plate 7 does not drive the driving plate 4 to slide through the wedge plate 8, at this moment, the reset spring 10 drives the shielding part 5 to reset in the process of restoring the elastic deformation, meeting the working requirements.
