Description

Technical Field

[0001] This utility model relates to the field of camera technology, and in particular to a camera with an externally mounted circuit board. Background Technology

[0002] Dome cameras, also known as PTZ cameras, are widely used in security monitoring due to their omnidirectional rotation and zoom capabilities. To achieve flexible angle adjustment, PTZ cameras integrate a sophisticated drive structure. In existing technologies, PTZ cameras are typically mounted using external brackets. Their core image processing and power control circuit boards, along with the drive structure and camera module, are encapsulated within a sealed dome-shaped housing. For a detailed description of their structure, refer to the highly practical intelligent surveillance camera disclosed in Chinese Patent Publication No. CN212137788U.

[0003] However, when the internal circuit board malfunctions, maintenance personnel must disassemble the entire PTZ camera from its bracket and open its precision-encapsulated housing to perform testing or replacement. This process is cumbersome, requires advanced maintenance skills, and is highly susceptible to damage to the delicate internal drive mechanism or cables during disassembly and assembly, potentially causing secondary malfunctions. Furthermore, the prolonged downtime for maintenance severely impacts the continuity and reliability of the monitoring system.

[0004] Therefore, in order to improve the ease of maintenance of the circuit board of existing PTZ cameras, we propose a camera with an external circuit board. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the cumbersome process of removing the entire PTZ camera from its support and opening its precision-encapsulated casing when the internal circuit board malfunctions, in order to perform testing or replacement. This invention proposes a camera with an externally mounted circuit board.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design an externally mounted camera on a circuit board, including:

[0008] Mounting frame and main unit mounted on the mounting frame;

[0009] The mounting bracket has a mounting cavity and a wiring cavity formed inside. A circuit board is fixedly mounted inside the mounting cavity, and the signal lines of the circuit board enter the host computer through the wiring cavity.

[0010] A wire clamping assembly is also provided inside the mounting cavity.

[0011] Furthermore, the wire pressing assembly includes a lifting plate, and a pressing part is formed below the lifting plate and placed in the wire routing cavity;

[0012] A flexible component is fixedly installed at the bottom of the clamping part.

[0013] Furthermore, guide grooves are provided on both sides of the lifting plate, and wedge-shaped portions are formed on both sides of the lifting plate located in the guide grooves.

[0014] An adjusting bolt is threaded inside the mounting cavity, and a driving block is movably connected to the outside of the adjusting bolt. The bottom of the driving block has a driving slope that matches the wedge-shaped portion.

[0015] Furthermore, a guide block is formed at the bottom of the drive block, and the guide block is slidably connected between the two wedge-shaped portions.

[0016] Furthermore, the bottom of the mounting bracket has a recessed area, in which a clearance opening is provided to avoid the interfaces and switches on the circuit board.

[0017] Furthermore, a cover plate is fixedly installed on the back end fastener of the mounting bracket, and the cover plate covers the outside of the mounting cavity.

[0018] The present invention proposes an externally mounted camera with the following advantages: By placing the internal circuit board of the camera inside the mounting bracket, when the circuit board needs to be repaired or replaced, there is no need to disassemble the camera body; the operation can be performed directly at the mounting bracket, which greatly simplifies the maintenance process and reduces maintenance costs and time.

[0019] In addition, the design of the wire clamping assembly can firmly clamp the signal line, effectively preventing the cable from loosening and ensuring the long-term stability and safety of signal transmission. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figure 1-6 As one embodiment of this utility model, it discloses an externally mounted camera. Specifically, the camera includes a mounting bracket 1 and a host 2 mounted on the mounting bracket 1. In this embodiment, the host 2 is preferably configured as a spherical camera, and its internal structure is prior art, which will not be described in detail here.

[0029] Specifically, in this embodiment, a mounting cavity 11 and a wiring cavity 12 are formed inside the mounting frame 1. A circuit board 13 is fixedly mounted inside the mounting cavity 11, and the signal lines of the circuit board 13 enter the host 2 along the wiring cavity 12.

[0030] In this embodiment, the circuit board 13 inside the camera is placed inside the mounting bracket 1. This design allows for convenient inspection and maintenance of the circuit board 13. When the circuit board 13 is damaged, the camera does not need to be disassembled, thus improving the convenience of maintenance. Of course, a cable inlet should also be opened at the bottom of the host 2. This cable inlet is connected to the cable routing cavity 12 to ensure that the signal can enter the host 2 through the cable routing cavity 12 to connect to various electrical components.

[0031] Of course, since this application only makes an adaptive change to the mounting position of the circuit board 13, without changing its circuit structure and principle, its specific structure and principle can be referred to the prior art, and will not be elaborated here.

[0032] Inside the mounting cavity 11, a wire clamping assembly 3 is provided to clamp and fix the signal wire, thereby ensuring the stability of the internal wiring and preventing the signal wire from shaking inside the mounting cavity 11 and the wiring cavity 12.

[0033] In some embodiments, the wire pressing assembly 3 of the present invention includes a lifting plate 31, and a pressing part 32 is formed below the lifting plate 31 and placed in the wiring cavity 12. By placing the pressing part 32 at the front opening of the wiring cavity 12, when the lifting plate 31 moves downward, the pressing part 32 can press and fix the signal line entering the wiring cavity 12, thereby achieving the purpose of fixing the signal line.

[0034] The bottom of the pressing part 32 is fixedly installed with a flexible part 33. Preferably, the flexible part 33 in this embodiment can be a rubber pad. The rubber pad is connected and fixed to the pressing part 32 by an adhesive method. The rubber pad design is used to improve the pressing protection of the signal line and avoid damage to the signal line caused by hard contact.

[0035] Based on the above embodiments, in this embodiment, guide grooves 34 are provided on both sides of the lifting plate 31, and wedge-shaped portions 35 are formed on both sides of the lifting plate 31 located in the guide grooves 34. The wedge-shaped portions 35 are protruding structures with an inclined surface.

[0036] An adjusting bolt 36 is threaded inside the mounting cavity 11, and a driving block 37 is movably connected to the outside of the adjusting bolt 36. The bottom of the driving block 37 has a driving inclined surface 38 that is adapted to the wedge-shaped part 35.

[0037] In other words, during the specific connection, the signal line inside the host 2 can first be routed along the wiring cavity 12 into the mounting cavity 11 and electrically connected to the circuit board 13. The specific connection method can be contact soldering or PIN pin socket connection.

[0038] After the connection is completed, by rotating the aforementioned adjusting bolt 36, since the adjusting bolt 36 is threadedly connected to the mounting cavity 11, its head end will abut against the driving block 37 and move downward. When the driving block 37 moves downward, it uses the inclined surface of the driving ramp 38 at its bottom and the inclined surface of the wedge 35 to drive the entire lifting plate 31 to move downward. In this way, the signal line at the wiring cavity 12 can be pressed and fixed by the flexible part 33. Preferably, in order to reduce the frictional force of the driving ramp 38 against the wedge 35, ball bearings can be embedded in the driving ramp 38. In this way, the stability of the ramp drive can be improved when pressing down.

[0039] Furthermore, in order to improve the movement stability of the drive block 37, the bottom of the drive block 37 in this embodiment is formed with a guide block 39, which is slidably connected between the two wedge-shaped portions 35. That is, in this embodiment, by slidably connecting the guide block 39 between the two wedge-shaped portions 35, its circumferential rotation is avoided, thereby improving the stability of the drive.

[0040] In some embodiments, the bottom of the mounting bracket 1 in this utility model has a recess 14, and the recess 14 has a clearance opening to avoid the interface and switch on the circuit board 13. That is, through the design of the recess 14, the power supply interface and toggle switch on the circuit board 13 can be exposed, and the power cord plug can be connected to the power supply socket during actual connection.

[0041] It should be noted that in this embodiment, a cover plate 15 is fixedly installed on the back end fastener of the mounting bracket 1. The cover plate 15 covers the outside of the mounting cavity 11. Of course, the fastener described in this embodiment can be a bolt. During maintenance, the cover plate 15 is first removed, and then the circuit board 13 is inspected.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
