[0057] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0058] Embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Reference will now be made in detail to preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numerals will be used throughout the drawings to represent the same or similar parts.

[0059] Furthermore, although the terms used in the present invention are selected from well-known and commonly used terms, some terms mentioned in the present specification may be selected by the applicant at his or her discretion, and their detailed meanings are explained in the relevant parts of the description herein.

[0060] Furthermore, it is required that the present invention be understood not only by the actual terms used but also by the meanings lying behind each term.

[0061] like Figures 1 to 4 As shown, the present invention discloses a camera guide rail device, which includes: an upper support plate 10, a guide rod 20, a support rail 30, a drag chain support plate 40, at least one running device 50 and at least one camera 60. Among them, the upper support plate 10, the guide rod 20, the support rail 30 and the drag chain support plate 40 are arranged in parallel with each other from top to bottom. The camera 60 is mounted on the corresponding running device 50, and the running device 50 is mounted on the guide rod 20 and slides along the support rail 30, thereby driving the camera 60 to move. The camera 60 is connected to an external mechanism via a drag chain 70, which is arranged on the drag chain support plate 40.

[0062] Preferably, the upper support plate 10, the guide rod 20, and the supporting rail 30 are connected at both ends by guide rod baffles 80, that is, the upper support plate 10 and the supporting rail 30 are connected by the guide rod baffles 80 on both sides. For example, the upper support plate 10 and the supporting rail 30 are respectively located at the upper and lower ends of the guide rod baffles 80, and the guide rod 20 is located in the middle of the guide rail baffles 80. The guide rod 20 here is preferably elongated or curved.

[0063] When the camera guide rail device needs to be fixed in the monitoring area, the various components are modularly assembled through the guide rod baffle 80 and the drag chain support plate 40.

[0064] Preferably, the walking device 50 includes a block-shaped body 51, a driven wheel 52, a driving wheel 53, a transmission module 54, and a motor 55. A guide rod hole 56 is provided in the block-shaped body 51, through which the walking device 50 is inserted into the guide rod 20. The walking device 50 is inserted into the guide rod 20 using the guide rod hole 56 and is driven by a motor 55 (e.g., a DC servo motor) to control the speed and direction of movement. The motor 55 is connected to the driving wheel 53 via a gear in the transmission module 54. When the motor 55 rotates, it drives the driving wheel 53, which cooperates with the driven wheel 52 to maintain the stability of the reciprocating motion of the walking device 50.

[0065] The driven wheel 52 and the driving wheel 53 are installed at the bottom of the block body 51, and the driven wheel 52 and the driving wheel 53 are installed in the slide groove 31 supporting the slide rail 30. The motor 55 and the transmission module 54 are installed on the block body 51 and connected to the driving wheel 53.

[0066] Furthermore, both ends of the drag chain support plate 40 are connected to the lower end of the guide rod baffle 80 through the first drag chain support plate bracket 41. A through hole 43 is provided on the drag chain support plate 40, and the drag chain 70 is passed through the through hole 43.

[0067] In addition, a second drag chain support plate bracket 42 is connected between the drag chain support plate 40 and the support rail 30 , that is, the support rail 30 and the drag chain support plate 40 are connected via the second drag chain support plate bracket 42 .

[0068] Multiple mounting blocks 90 are mounted on the upper support plate 10 and the drag chain support plate 40. A cable slider 32 is mounted on the support rail 30. One end of the cable 100 is connected to the cable slider 32 and connected to the drag chain 70. A connector 61 is mounted on the bottom of the camera 60, and the other end of the cable 100 is connected to the connector 61.

[0069] The cable slider 32 is mounted on the T-shaped structure of the support rail 30 and is used to fix the cable routing of the running gear 50. The cable of the running gear 50 is wrapped in a drag chain, one end of which is fixed to the cable slider 32 and the other end is fixed to the through hole of the drag chain support plate 40. This ensures that the short drag chain is always located in the U-shaped drag chain support plate 40 when the running gear 50 moves.

[0070] The camera 60 is mounted on a connector 61 on the travel device 50. The travel device 50 extends through the guide rod 20 and is structurally supported by a drive wheel 53 and a driving wheel 52, which are embedded in a U-shaped chute. A motor 55 (e.g., a DC servo motor) is fixed to the cable slider 32. The DC servo motor connection is distributed through the connector 61 in the connecting cable. The gears of the DC servo motor mesh with the gears of the drive wheel 53 through the gear structure in the transmission module 54. When the motor 55 is running, it drives the drive wheel 53 to move on the U-shaped chute, thereby enabling the camera 60 to move back and forth along the guide rod 20 on the guide rail assembly.

[0071] After the motor 55 (such as a DC servo motor) control cable 100 is routed from the walking device, it is combined with the camera 60 control cable into one cable through the connector 61. After being wrapped by the drag chain, it is connected to the central control room through the through hole 43 on the drag chain support plate 40, without the need for additional power supply to the guide rail device.

[0072] The components of the camera rail device are made of metal materials and are designed to be bilaterally symmetrical with the through hole 43 on the drag chain support plate 40 as the center. They are fixed in position by welding multiple mounting blocks 90 on the upper support plate 10 and the drag chain support plate 40 or by bolt holes on the mounting plate.

[0073] Based on the structural description above, in the camera rail device of the present invention, the upper support plate 10, support rail 30, and drag chain support plate 40 are preferably U-shaped, effectively enhancing the support plate strength. The widths of the upper support plate 10 and support rail 30 are preferably identical, and the width of the drag chain support plate 40 is consistent with the height of the guide bar baffle 80. The support rail 30 includes a central groove for the movement of the drive wheel 53 and driven wheel 52 of the traveling device 50.

[0074] The cables of the traveling device 50 are wrapped in a drag chain, with the ends fixed to the cable sliders 32. This ensures that the cables are not pulled by excessive traction when the traveling device 50 moves, and prevents the drag chain from escaping the U-shaped groove of the drag chain support plate 40 when the traveling device 50 moves back and forth. The cable sliders 32 are mounted on the T-shaped structure of the support rails 30 and are used to fix the cable routing of the traveling device 50.

[0075] The camera guide rail device of the present invention is suitable for a guide rail device for a surveillance camera to move back and forth in a straight line or arc, which can effectively improve the application range of the surveillance camera, so that the surveillance camera can not only be used for monitoring a fixed environment, but also can be moved to a relatively far place for monitoring through the surveillance camera guide rail device, and the video data captured by the surveillance camera can be transmitted to the central control room through the video surveillance network, so that the central control room can timely grasp the situation within the monitoring range.

[0076] In addition, the movement of the walking device on the camera rail device and the transmission of the light, pan / tilt, and video signals on the camera are all achieved through one cable, avoiding the situation where there is no additional power supply for the track device at the monitoring site, and simplifying the cable layout.

[0077] In summary, the camera rail device of the present invention has the following advantages:

[0078] 1. The surveillance camera can move back and forth along the guide rod on the track under the movement of the walking device, which increases the monitoring range of the camera;

[0079] 2. After the DC servo motor control cable is routed from the walking device, it is combined with the camera control cable into one cable through a connector, eliminating the need for additional power supply to the guide rail device.

[0080] 3. The connecting cables between the motor and camera on the guide rail device are placed in the drag chain support plate through the drag chain, eliminating the risk of cable entanglement when the surveillance camera moves back and forth;

[0081] 4. The limited connection mode ensures reliable control of the guide rail device and stable transmission of camera video images;

[0082] 5. Different from the previous solution of using a motor to drive a lead screw to move the camera, this structure in which the camera travel device is driven separately can ensure that the camera can be moved on long tracks or curved tracks. As long as the length is designed according to different environments, there is no distance limitation.
