Description

Technical Field

[0001] This utility model relates to the field of monitoring equipment technology, and in particular to a camera for the driver's cab of a rail transit locomotive. Background Technology

[0002] With the continuous development of electronic surveillance technology and technological advancements, cameras are used in various locations to protect people's safety and interests. Cameras are the most common type of camera, typically mounted on walls and ceilings, and their monitoring angle is adjustable.

[0003] Currently, some rail transit locomotive driver's cab cameras are modularized, mainly consisting of a spherical transparent cover, a spherical light shield, a base, a camera assembly, and an angle adjustment bracket. The camera assembly is mounted on the base via the angle adjustment bracket, which allows adjustment of the camera assembly's monitoring angle. A spherical light shield is used to conceal the internal components of the camera and to block light from other directions. The spherical light shield has an opening to expose the camera assembly. The spherical transparent cover and the spherical light shield are generally screwed onto the base. However, when the camera assembly angle is adjusted, the spherical transparent cover and the spherical light shield are difficult to match the camera assembly angle, and the spherical light shield is also difficult to handle the influence of external light through fine adjustments, which needs improvement. Utility Model Content

[0004] The purpose of this utility model is to provide a camera for the driver's cab of a rail transit locomotive, which is not only easy to install and disassemble, but also makes it easier to adjust the monitoring angle and fine-tune the spherical light shield.

[0005] This utility model is implemented as follows: a camera for the driver's cab of a rail transit locomotive includes a spherical transparent cover, a spherical light shield, a middle shell, a base, a sealing ring, an external threaded fixing ring, a camera assembly, and an angle adjustment bracket. The camera assembly is mounted on the base via the angle adjustment bracket, and the spherical light shield has an opening for exposing the camera assembly.

[0006] The middle shell extends inward to form a positioning flange at one end that mates with the spherical transparent cover. The inner wall of the middle shell inside the positioning flange is also provided with an internal thread. The external thread fixing ring is screwed into the internal thread of the middle shell. The sealing ring, the spherical transparent cover and the spherical light shield are pressed between the positioning flange and the external thread fixing ring from the outside to the inside.

[0007] The base has a boss on its inner side and an annular groove on its side. The middle shell is fitted onto the boss, and the bottom surface of the middle shell abuts against the inner surface of the base. The middle shell has a positioning hole at a position corresponding to the annular groove on its side. A set screw is provided at the positioning hole, and the inner side of the set screw extends into the annular groove to fix the middle shell on the base.

[0008] The base is also equipped with a microphone, which is electrically connected to the camera assembly via a cable.

[0009] The camera assembly is also fitted with a fill light plate, which is equipped with a fill light and a light sensor.

[0010] The external thread retaining ring has two grooves for engaging with a tightening tool.

[0011] The annular groove on the side of the boss has an inclined surface on one side, and the set screw abuts against the inclined surface to press the middle shell against the base.

[0012] The outer wall of the base is also provided with a ring of strip teeth.

[0013] The beneficial effects of this utility model are as follows: The camera in the driver's cab of the rail transit locomotive of this application adds a middle shell, on which the spherical transparent cover and the spherical light shield are fixed. A sealing ring is set to ensure the sealing effect and prevent dust and flying insects from entering. Then the whole is fitted onto the base. Since there is an annular groove on the side of the inner boss of the base and a positioning hole on the side of the middle shell, the set screw extends into the annular groove to fix the middle shell on the base. The camera is easy to disassemble and assemble. After disassembly, the monitoring angle can be adjusted. Before the set screw is locked, the middle shell, the spherical transparent cover and the spherical light shield can rotate around the axis as a whole, so it is very convenient to make fine adjustments to the spherical light shield.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] As an embodiment of the rail transit locomotive driver's cab camera described in this utility model, such as Figures 1 to 7 As shown, it includes a spherical transparent cover 1, a spherical light shield 2, a middle shell 3, a base 4, a sealing ring 5, an external threaded fixing ring 6, a camera assembly 7, and an angle adjustment bracket 8. The camera assembly 7 is mounted on the base 4 via the angle adjustment bracket 8. The spherical light shield 2 has an opening 21 for exposing the camera assembly 7.

[0024] The middle shell 3, which mates with the spherical transparent cover 1, extends inward to form a positioning flange 31. The inner wall of the middle shell 3 inside the positioning flange 31 is also provided with an internal thread. The external thread fixing ring 6 is screwed onto the internal thread of the middle shell 3. The sealing ring 5, the spherical transparent cover 1, and the spherical light shield 2 are pressed between the positioning flange 31 and the external thread fixing ring 6 from the outside to the inside.

[0025] The base 4 has a boss 41 on its inner side, and an annular groove 42 on the side of the boss 41. The middle shell 3 is fitted onto the boss 41, and the bottom surface of the middle shell 3 abuts against the inner surface of the base 4. A positioning hole 32 is provided on the side of the middle shell 3 at a position corresponding to the annular groove 42. A set screw 9 is provided at the positioning hole 32, and the inner side of the set screw 9 extends into the annular groove 42 to fix the middle shell 3 on the base 4. In this embodiment, there are two set screws 9, arranged symmetrically.

[0026] This application for a rail transit locomotive driver's cab camera adds a middle shell 3, on which the spherical transparent cover 1 and the spherical light shield 2 are fixed. A sealing ring 5 is set to ensure a sealing effect and prevent dust and flying insects from entering. Then, the whole unit is fitted onto the base 4. Since there is an annular groove 42 on the side of the inner boss 41 of the base 4, and a positioning hole 32 on the side of the middle shell 3, the set screw 9 extends into the annular groove 42 to fix the middle shell 3 to the base 4. The rail transit locomotive driver's cab camera is easy to assemble and disassemble. After disassembly, the monitoring angle can be adjusted. Before the set screw 9 is locked, the middle shell 3, the spherical transparent cover 1 and the spherical light shield 2 can rotate around the axis as a whole, so it is very convenient to make fine adjustments to the spherical light shield 2.

[0027] In this embodiment, refer to Figure 1 The base 4 is also equipped with a microphone 10 for picking up ambient sounds. The microphone 10 is electrically connected to the camera assembly 7 via a cable.

[0028] In this embodiment, refer to Figure 6 The camera assembly 7 is also fitted with a fill light plate 11, which is equipped with a fill light 111 and a light sensor 112. The light sensor 112 senses the intensity of ambient light. When the light is insufficient, the fill light 111 will be turned on to provide supplementary light, so as to ensure a good monitoring effect at night and on cloudy days.

[0029] In this embodiment, refer to Figure 7 The external thread retaining ring 6 is provided with two grooves 61 for cooperating with a tightening tool. The external thread retaining ring 6 can be rotated using a special tool to tighten the threads.
