Description

Technical Field

[0001] The utility model relates to the technical field of camera modules, and specifically relates to a high-definition and high-dynamic-range camera module. Background Technique

[0002] A high-definition and high-dynamic-range camera module is a modular product integrating components such as a high-definition camera, an image sensor, and a digital signal processor. Among them, multiple sensor components are installed and fixed on a circuit board, and the circuit board is arranged behind the high-definition camera. The characteristic of this module is that it can provide images with high resolution and high dynamic range, so that clear and detailed pictures can be captured under various light conditions. Therefore, high-definition and high-dynamic-range camera modules are often used to shoot wild animals outdoors;

[0003] On a traditional high-definition and high-dynamic-range camera module, it is generally connected to the camera through a circuit board. Because multiple auxiliary shooting sensors need to be installed on a single circuit board, the size of the circuit board is designed to be relatively large, resulting in a relatively large overall volume of the high-definition and high-dynamic-range camera module for outdoor shooting, which is not convenient for hidden shooting. And sometimes when an animal discovers the camera, it will touch the lens of the camera, and it is easy for stains to adhere to the outside of the lens, affecting high-definition shooting. Content of the Utility Model

[0004] The purpose of the utility model is to provide a high-definition and high-dynamic-range camera module to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution:

[0006] A high-definition and high-dynamic-range camera module includes a housing. One end of the housing is detachably fixed with a panel. A high-definition camera is detachably inserted and fixed in the middle of the panel. A plurality of lens components are arranged outside the lens of the high-definition camera. A lead screw for driving the lens components to move is rotatably connected inside the panel. Two circuit boards are detachably installed and fixed at one end of the high-definition camera away from the lens components. A flexible circuit board is detachably electrically connected between the two circuit boards. There is a gap between the two circuit boards. Longitudinal holes for heat dissipation at the gap position are opened inside both sides of the housing.

[0007] Furthermore: A transverse hole one communicating with the gap position is opened at the top of the longitudinal hole. A transverse hole two communicating with the outside is opened at the bottom of the longitudinal hole. A filter screen is detachably installed and fixed outside the transverse hole two.

[0008] Furthermore: A card slot is arranged outside one of the circuit boards. An SD card is detachably inserted into the card slot. A socket is fixed on the top of the circuit board. Plugs that are movably inserted into the socket are fixed at both ends of the flexible circuit board.

[0009] Furthermore, two first mounting blocks are fixed to both the inner top and inner bottom of the housing, two second mounting blocks are fixed to both the inner top and inner bottom of the housing, and a baffle cover is detachably fixed to the open end of the housing.

[0010] Furthermore, one end of the high-definition camera is fixed with a mounting plate, fixing seats are fixed to both ends of the mounting plate, and the fixing seats are detachably fixedly connected to the circuit board by screws.

[0011] Furthermore, the lens assembly includes an annular frame, a glass plate is fixed inside the annular frame, the lead screw is screwed to a plurality of annular frames, and an arc plate is fixed to the outside of the panel.

[0012] Furthermore, a motor for driving the lead screw to rotate is fixed to the inner side of the panel, a limiting shaft is fixed inside the panel, and the limiting shaft is slidably connected to a plurality of annular frames.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. By setting the single circuit board on the traditional camera module into two circuit boards electrically connected by a flexible circuit board, and separately installing different electronic components and sensor components in the prior art on the two circuit boards, it is beneficial to reduce the overall volume of the camera module, facilitate hiding the camera module for installation in outdoor tree or stone crevices to photograph wild animals, and leave a gap between the two circuit boards, so that external air can enter the longitudinal hole through the second transverse hole and then be transported to the gap position through the first transverse hole, which is convenient for dissipating heat from the circuit board.

[0015] 2. After an animal attacks the housing and causes damage to the camera module, the baffle cover can be removed first, then the flexible circuit board can be taken off, and finally the circuit boards at different positions can be separately disassembled, which is convenient for targeted repair of the electronic components or sensor components on a certain position circuit board.

[0016] 3. The motor drives the lead screw to rotate, so that the annular frame screwed to it drives the glass plate to move away from the motor, so that a plurality of lens assemblies outside the high-definition camera lens can sequentially disengage from the high-definition camera lens. When the glass plate of the outermost lens assembly is dirty, the dirty glass plate can be automatically disassembled by rotating the lead screw, and the clean glass plate behind the dirty glass plate can be moved out, which is beneficial to keeping the high-definition camera for high-definition shooting.

Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment 1. Please refer to Figures 1-5 , in the embodiment of the present utility model, a high-definition and high-dynamic camera module includes an outer shell 100. One end of the outer shell 100 is detachably fixed with a panel 110. A high-definition camera 200 is detachably inserted and fixed in the middle of the panel 110. A plurality of lens assemblies 300 are arranged outside the lens of the high-definition camera 200. A lead screw 111 for driving the movement of the lens assembly 300 is rotatably connected inside the panel 110. Two circuit boards 400 are detachably installed and fixed at one end of the high-definition camera 200 away from the lens assembly 300. A flexible circuit board 410 is detachably electrically connected between the two circuit boards 400. There is a gap between the two circuit boards 400. Longitudinal holes 120 for dissipating heat at the gap position are opened in both internal sides of the outer shell 100.

[0025] Specifically, by configuring the single large-sized circuit board 400 on the traditional high-definition and high-dynamic camera module into two smaller-sized circuit boards 400, and separately installing different electronic parts and sensor components on the two circuit boards 400, it is helpful to reduce the overall volume of the camera module, and convenient to hide the camera module to shoot wild animals. By arranging multiple lens assemblies 300 in front of the lens of the high-definition camera 200, the glass plate 320 on the dirty lens assembly 300 can be detached from the lens of the high-definition camera 200 by rotating the screw 111, so that the spare clean glass plate 320 is blocked in front of the lens, which is helpful to ensure that the front side of the lens is clean and tidy, and prevent the dirty lens from affecting the high-definition recording of the high-definition camera 200.

[0026] like Figure 1 and Figure 5 As shown, in this embodiment, the top of the longitudinal hole 120 is connected to a transverse hole 121 connected to the gap position, and the bottom of the longitudinal hole 120 is connected to a transverse hole 2 122 connected to the outside, and a filter 130 is detachably installed and fixed on the outer side of the transverse hole 2 122.

[0027] In this embodiment, outside air can enter the gap between the two circuit boards 400 through the second transverse hole 122, the longitudinal hole 120 and the first transverse hole 121 in sequence, which is beneficial to the heat dissipation of the circuit board 400. The filter 130 prevents foreign matter from entering the interior of the housing 100, and the first transverse hole 121 and the second transverse hole 122 are staggered to prevent rainwater from entering the first transverse hole 121 from the second transverse hole 122.

[0028] like Figure 3 As shown, in this embodiment, a card slot 420 is provided on the outer side of a circuit board 400, and an SD card 421 is removably inserted inside the card slot 420. A socket 430 is fixed on the top of the circuit board 400, and plugs that are movably connected to the socket 430 are fixed at both ends of the flexible circuit board 410.

[0029] In this embodiment, an SD card 421 is installed on the circuit board 400 for temporarily caching video data or saving key frames when power is off. When the camera system suddenly loses power or a power failure occurs, this function can ensure that the system captures and saves key frames or key information in the video before losing power.

[0030] like Figure 2 As shown, in this embodiment, two mounting blocks 150 are fixed to the inner top and inner bottom of the shell 100, two mounting blocks 160 are fixed to the inner top and inner bottom of the shell 100, and a baffle cover 140 is detachably fixed to the open end of the shell 100.

[0031] In this embodiment, the first mounting block 150 and the second mounting block 160 are used to limit the positions of the two circuit boards 400 inside the housing 100, facilitating the installation and fixation of the circuit boards 400 at predetermined positions. Among them, the first mounting block 150 is arranged between the two circuit boards 400.

[0032] As Figure 3 shown, in this embodiment, a mounting plate 210 is fixed to one end of the high-definition camera 200. Fixing seats 211 are fixed to both ends of the mounting plate 210. The fixing seats 211 are detachably and fixedly connected to the circuit board 400 by screws.

[0033] In this embodiment, when it is necessary to disassemble the high-definition camera 200, the panel 110 can be disassembled first, and then the screws on the fixing seat 211 can be disassembled with a screwdriver from the position of the panel 110, so that the mounting plate 210 can be detached from the circuit board 400 together with the high-definition camera 200.

[0034] Embodiment 2, on the basis of Embodiment 1, in order to keep the front side of the lens of the high-definition camera 200 clean and tidy.

[0035] As Figure 1 and Figure 4 shown, in this embodiment, the lens assembly 300 includes an annular frame 310. A glass plate 320 is fixed inside the annular frame 310. The lead screw 111 is threadedly connected to a plurality of annular frames 310. An arc plate 114 is fixed to the outside of the panel 110. A motor 112 for driving the lead screw 111 to rotate is fixed to the inside of the panel 110. A limiting shaft 113 is fixed inside the panel 110. The limiting shaft 113 is slidably connected to a plurality of annular frames 310.

[0036] Specifically, when it is necessary to replace the dirty glass plate 320 at the forefront of the lens, the motor 112 drives the lead screw 111 to rotate, so that the annular frame 310 threadedly connected to it drives the glass plate 320 to slide along the limiting shaft 113. When the annular frame 310 disengages from the limiting shaft 113, it will fall off, so that the dirty glass plate 320 on the outermost side of the lens is disassembled, and the clean glass plate 320 behind the dirty glass plate 320 is exposed to block the front side of the lens. Thus, the front side of the lens is always kept clean and tidy, which is beneficial to the high-definition camera 200 for high-definition video recording. The arc plate 114 blocks above the plurality of lens assemblies 300 to prevent rainwater from dripping between adjacent glass plates 320 from above.

[0037] In the present utility model, the high-definition camera 200 cooperates with various electronic components and sensor components on the circuit board 400 for high-definition and high-dynamic video recording, which is prior art, and the specific video recording principle will not be elaborated here; when installing this high-definition and high-dynamic camera module, a battery block can be synchronously installed at a hidden position to supply power to the camera module. Of course, other different power supply methods can also be adopted according to actual working needs.

[0038] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.

[0039] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
