Technical Field
[0001] This invention relates to the field of monitoring equipment installation technology, specifically to a track-mounted camera that is easy to power and operate. Background Technology
[0002] Patent application CN214756563U includes a magnetic rail for mounting on a wall or ceiling. The magnetic rail has a sliding groove containing a continuous conductor connected to an electrical grid. A magnetic rail box is detachably connected to the sliding groove and can slide within it. The magnetic rail box has contacts that conduct electricity to the conductor, allowing it to connect to the electrical grid. A camera module is connected to the magnetic rail box, and the magnetic rail box and camera module are electrically connected to provide power to the camera module. The advantages are: it overcomes the shortcomings of existing technologies and provides a track-mounted movable camera that can be flexibly adjusted in position and is easy to use.
[0003] Existing surveillance cameras installed on rail lighting systems operate as follows: a continuous conductive body (usually a copper strip) is placed inside the rail, and an adapter connects to the rail via magnetic attraction or plug-in connection. The brush contacts on the adapter form an electrical path with the conductive body, introducing the current supplied by the rail into the adapter's internal circuit. After voltage conversion, the current powers the camera. Users can manually slide the adapter along the rail to adjust the monitoring position. Some improved solutions use motor-driven wheels for automatic sliding and utilize wireless power supply technology to power the camera through electromagnetic induction between the power output coil and the receiving coil, avoiding the dragging of power cords. Another integrated solution mounts the camera and lighting fixtures together on the same rail system, enabling simultaneous lighting dimming and video monitoring functions through a control panel. The images acquired by the camera are transmitted to a display or storage device via a data processor.
[0004] While most existing technologies, including the aforementioned patents, simplify the installation process to some extent, they still have several significant shortcomings in practical applications: Most existing track camera adapters use a fixed brush structure. After the adapter is inserted into the guide rail, the brush maintains continuous contact with the conductive strip. When the camera position needs to be adjusted according to monitoring requirements, the adapter must be slid along the track while energized, resulting in sliding friction between the brush and the conductive strip. Long-term use can easily lead to scratches on the conductive strip surface and wear on the brush, which in turn can cause increased contact resistance, unstable power supply, or even power failure. If the power is cut off before moving the camera to protect the conductive strip, it is necessary to reposition and re-energize it, which is cumbersome and cannot achieve real-time flexible adjustment of the monitoring angle. As a power supply conductor that is exposed for a long time, the guide rail is prone to accumulating dust and other contaminants on its surface. Existing technologies lack an effective automatic cleaning mechanism. Contaminants adhere to the surface of the conductive strip as the usage time increases. When the brush comes into contact with it, a contamination layer is easily formed at the contact interface, leading to poor contact, local heating, or even signal interruption, which seriously affects the operational reliability and service life of the camera. Summary of the Invention
[0005] The problem this invention aims to solve is that existing surveillance cameras installed based on guide rail lighting systems are prone to wear due to continuous friction between the brushes and conductive strips during movement and adjustment, and the lack of a cleaning mechanism for dust accumulation on the guide rail surface can easily lead to poor contact.
[0006] To solve the above-mentioned technical problems, the technical solution of the present invention is: a track-mounted camera that is easy to operate with power supply, including a track bar, an adapter housing and a camera. The adapter housing is inserted into the track bar, and a fixing seat is fixedly connected to the top of the adapter housing. The fixing seat is fixedly connected to the base of the camera by bolts.

The blowing mechanism consists of a piston assembly and a first moving assembly, and the suction mechanism consists of a piston assembly and a second moving assembly. The piston assembly includes a piston housing and a piston plate. The piston plate slides up and down inside the piston housing. The first moving assembly and the second moving assembly are both located on the top of the piston housing.
[0007] Preferably, the tops of the two brushes are adapted to the slots in the groove at the bottom center of the fixing plate, the bottoms of the two brushes are adapted to the inclined surface at the top of the limiting block, and the L-shaped rod can move laterally within the sliding hole of the fixing plate.
[0008] Preferably, the fixing block penetrates the side wall of the adapter housing, and the two inner side walls of the track are provided with fixing grooves, and the fixing block is adapted to the fixing grooves.
[0009] Preferably, the bottoms of the two brushes are smooth and adhere to the two conductive strips.
[0010] Preferably, the push block is slidably connected to the slide groove on the top plate of the adapter housing. Circular grooves are provided on both sides of the slide groove. A limiting component is provided in the circular groove. The limiting component includes a limiting post with a circular head at its front end. The limiting post is inserted into the circular groove. A spring is sleeved on the outside of the limiting post. The two ends of the spring are fixedly connected to the rear end of the circular head and one end of the circular groove, respectively. A groove that matches the circular head of the limiting post is provided in the middle of both ends of the push block.
[0011] Preferably, the movable component one includes a telescopic component and two movable blocks one. The telescopic component includes two movable columns. One end of each movable column movably passes through the top of the piston housing and is fixedly connected to the top of the piston plate. A limiting seat is sleeved on the outside of the movable column. The bottom of the limiting seat is fixedly connected to the top of the piston housing. A spring two is sleeved on the outside of the movable column. The two ends of the spring two are fixedly connected to the top of the limiting seat and the bottom of the top ring of the movable column, respectively. A rotatable roller is installed on the top of the movable column.
[0012] Preferably, the first movable block is an inverted trapezoid, the first movable block movably penetrates the side wall of the adapter housing, a third spring is provided on one side of the top of the first movable block, one end of the third spring is fixedly connected to the protrusion on the top of the first movable block, the other end of the third spring is fixedly connected to the inner side wall of the adapter housing, and the inclined side of the first movable block inside the adapter housing is in contact with the roller.
[0013] Preferably, the second movable component includes a telescopic component and two second movable blocks. The second movable block is a parallelogram and movably penetrates the side wall of the adapter housing. A third spring is provided at the bottom of the second movable block, and the two ends of the third spring are fixedly connected to a protrusion at one end of the bottom of the second movable block and the side wall of the adapter housing, respectively. The bottom ends of the two movable columns inside the telescopic component are connected by a connecting rod. The connecting rod is movably connected to the bottom wall of the top plate of the adapter housing through two connecting columns. Two cylinders are fixedly connected to the bottom of the connecting rod. The cylinders movably penetrate the top of the piston box and are fixedly connected to the piston plate. The inclined side of the second movable block inside the adapter housing is in contact with the roller.
[0014] Preferably, a first air guide plate and a second air guide plate are fixedly connected to both sides of the bottom end of the piston box, and the top of the first air guide plate and the second air guide plate have an inclined surface, which forms an angle of 30°-60° with the horizontal plane.
[0015] Preferably, the inclination directions of the first and second air guide plates of the suction mechanism are opposite to those of the first and second air guide plates of the blowing mechanism. The blowing mechanism guides the airflow generated by the piston assembly to the surface of the conductive strip of the track bar, and the suction mechanism sucks in the air blown out by the piston assembly of the blowing mechanism as well as the dust.
[0016] Compared with the prior art, the technical solution of the present invention has the following advantages: (1) By setting up a power-on fixing component, an air blowing mechanism, and an air suction mechanism, the camera can be quickly powered and the conductive strip and brush can be effectively protected from wear during the camera movement. At the same time, the surface of the conductive strip is automatically cleaned during the insertion of the adapter into the track, effectively preventing poor contact caused by dust accumulation. The magnet built into the bottom of the adapter housing and the magnetic material of the track generate magnetic attraction, so that the adapter housing is initially attracted to the track to achieve rapid pre-positioning. At this time, the brush is in the retracted state and detached from the conductive strip, and the fixing block is also in the retracted state and not engaged with the fixing groove. Therefore The adapter housing can slide freely on the track, allowing users to slide the camera to any position according to their monitoring needs. Throughout the sliding process, the brush remains separated from the conductive strip, completely avoiding scratches and wear caused by friction between the brush and the conductive strip during the adjustment of traditional track cameras. After the user determines the position, they push the push block, and the L-shaped rod drives the brush to descend along the inclined surface of the limit block and extend to fit tightly against the conductive strip to complete the power supply connection. At the same time, the fixing block extends and inserts into the fixing groove of the track to achieve mechanical locking. This effectively solves the pain points of existing track cameras that cannot be adjusted after installation or require power disconnection during adjustment and are prone to wear on the conductive strip. (2) When the adapter housing is inserted into the track bar, the edge of the track bar pushes the moving block one and the moving block two to retract inward. The inclined side of the moving block one pushes the roller to make the piston move downward. Compressed air is blown onto the surface of the conductive strip at an angle of 30°-60° through the air guide plate, forming a directional blowing airflow, which effectively removes the dust and particles accumulated on the surface of the conductive strip. At the same time, the moving block two drives another piston assembly to work through the connecting rod. Its air guide plate forms a negative pressure area, which sucks the dust raised by the blowing mechanism and the residual dust on the surface of the conductive strip into the piston box for temporary storage. This is completed before the brush contacts the conductive strip, ensuring the cleanliness of the contact surface and greatly reducing the risk of failure such as poor contact, overheating or power failure caused by dust accumulation.

[0021] like Figures 1 to 9 As shown, the present invention provides a track-mounted camera that is easy to operate with power supply, including a track bar 1, an adapter housing 2, and a camera 4. The adapter housing 2 is inserted into the track bar 1. The magnet (not shown in the figure) built into the bottom of the adapter housing 2 generates a magnetic attraction force with the magnetic material of the track bar 1, so that the adapter housing 2 is initially attracted to the track bar 1. The top of the adapter housing 2 is fixedly connected to the fixing base 3. The fixing base 3 is fixedly connected to the base of the camera 4 by bolts to realize the stable installation of the camera 4, thereby fixing the adapter housing 2 and the camera 4. The inner bottom wall of the track bar 1 is provided with two conductive strips 101, which serve as positive and negative power supply conductors, respectively. The middle of the interior of the adapter housing 2 is provided with an internal box 202. Both sides of the internal box 202 are provided with power-conducting fixing components. The power-on fixing assembly includes a push block 5 and an L-shaped rod 501. The bottom of the push block 5 is fixedly connected to one end of the L-shaped rod 501, and a brush 503 is movably connected to the other end of the L-shaped rod 501. A fixing plate 204 is fixedly connected to the inner bottom of the adapter housing 2. The L-shaped rod 501 passes through a sliding hole in the fixing plate 204. A limit block 504 is fixedly connected to the bottom of the fixing plate 204. Fixing blocks 502 are fixedly connected to both ends of the top horizontal bar of the L-shaped rod 501. A circuit board is provided inside the inner box 202, and a power converter is integrated on the circuit board. The replacement module and overcurrent protection module are installed in the built-in box 202, which is electrically connected to the brushes 503 on both sides through internal wires. When the brushes 503 contact the conductive strip 101, the track current is introduced into the circuit board of the built-in box 202 through the brushes 503, L-shaped rod 501 and internal wires. After voltage conversion and regulation, it is transmitted to the output interface at the bottom of the fixed base 3 through a flexible cable. The bottom of the fixed base 3 is provided with electrical contacts or standard power interfaces that are compatible with the base of the camera 4. After the camera 4 is installed, it is connected to the output interface, realizing immediate use. Built-in Box 202 has Built-in Box 1 201 and Built-in Box 3 203 on its two sides respectively. Built-in Box 1 (201) can be equipped with a wireless communication module, energy storage unit or environmental sensor. Built-in Box 3 (203) can be equipped with a PoE power supply module, audio processing module or status indicator light drive circuit. Built-in Box 1 (201) and Built-in Box 3 (203) are electrically connected to Built-in Box 2 (202) through internal wiring to realize power supply and data interaction. An air blowing mechanism is provided between Built-in Box 1 201 and Built-in Box 2 202. An air suction mechanism is provided between Built-in Box 3 203 and Built-in Box 2 202. The blowing mechanism consists of a piston assembly and a first moving assembly, and the suction mechanism consists of a piston assembly and a second moving assembly. The piston assembly includes a piston housing 6 and a piston plate 601. The piston plate 601 slides up and down inside the piston housing 6. The first and second moving assemblies are both located on the top of the piston housing 6. The blowing and suction mechanisms serve as pneumatic cleaning units to automatically remove dust from the surface of the conductive strip 101 during the insertion of the adapter housing 2 into the track strip 1, ensuring good contact between the brush 503 and the conductive strip 101.
[0022] In one embodiment of the present invention, the tops of the two brushes 503 are adapted to the slots in the grooves in the middle of the bottom of the fixing plate 204, and the bottoms of the two brushes 503 are adapted to the inclined surface of the top of the limiting block 504. The L-shaped rod 501 can move laterally in the sliding hole of the fixing plate 204. The fixing block 502 penetrates the side wall of the adapter housing 2. The two inner side walls of the track bar 1 are provided with fixing grooves 102. The fixing block 502 is adapted to the fixing grooves 102. The bottoms of the two brushes 503 are smooth and fit against the two conductive strips 101. When the L-shaped rod 501 moves laterally, the brushes 503 move along the inclined surface of the limiting block 504 to achieve lifting and lowering. In the initial state, the brush 503 is in the retracted position and disengaged from the conductive strip 101. When the push block 5 is pushed, the L-shaped rod 501 drives the brush 503 to move laterally. The bottom of the brush 503 descends along the inclined surface of the limiting block 504 and moves down along the bottom end of the L-shaped rod 501, causing the top of the brush 503 to disengage from the slot of the fixing plate 204. At the same time, the bottom of the brush 503 extends out and fits against the conductive strip 101, completing the power supply connection. Meanwhile, the fixing block 502 at the top of the L-shaped rod 501 extends out of the side wall of the adapter housing 2 and inserts into the fixing groove 102 of the track 1, realizing the mechanical locking between the adapter housing 2 and the track 1, preventing the adapter from falling off due to vibration or external force during use. The smooth bottom design of the two brushes 503 ensures good contact when they fit against the conductive strip 101, reducing contact resistance.
[0023] In one embodiment of the present invention, the push block 5 is slidably connected to the slide groove opened on the top plate of the adapter housing 2. Circular grooves are opened on both sides of the slide groove. A limiting component is provided in the circular groove. The limiting component includes a limiting post 505. The front end of the limiting post 505 is a circular head. The limiting post 505 is inserted into the circular groove. A spring 506 is sleeved on the outside of the limiting post 505. The two ends of the spring 506 are fixedly connected to the rear end of the circular head and one end of the circular groove, respectively. The middle of both ends of the push block 5 is provided with a groove that matches the circular head of the limiting post 505. When the push block 5 moves to the designated position, the circular head of the limiting post 505 is engaged in the groove of the push block 5 under the action of the spring 506, providing a clear sense of positioning and keeping the position of the push block 5 stable, preventing the push block 5 from retracting due to vibration.
[0024] In one embodiment of the present invention, the movable component 1 includes a telescopic component and two movable blocks 8. The telescopic component includes two movable columns 7. One end of the movable column 7 movably passes through the top of the piston housing 6 and is fixedly connected to the top of the piston plate 601. A limiting seat 703 is sleeved on the outside of the movable column 7. The bottom of the limiting seat 703 is fixedly connected to the top of the piston housing 6. A second spring 701 is sleeved on the outside of the movable column 7. The two ends of the second spring 701 are fixedly connected to the top of the limiting seat 703 and the bottom of the top ring of the movable column 7, respectively. A rotatable roller 702 is installed on the top of the movable column 7.
[0025] In one embodiment of the present invention, the movable block 8 is an inverted trapezoid and moves through the side wall of the adapter housing 2. A spring 801 is provided on one side of the top of the movable block 8. One end of the spring 801 is fixedly connected to the protrusion on the top of the movable block 8, and the other end of the spring 801 is fixedly connected to the inner side wall of the adapter housing 2. The inclined side of the movable block 8 inside the adapter housing 2 is in contact with the roller 702.
[0026] In one embodiment of the present invention, the second movable component includes a telescopic component and two second movable blocks 802. The second movable block 802 is a parallelogram and movably penetrates the side wall of the adapter housing 2. A third spring 801 is provided at the bottom of the second movable block 802. The two ends of the third spring 801 are respectively fixedly connected to a protrusion at one end of the bottom of the second movable block 802 and the side wall of the adapter housing 2. The bottom ends of the two movable columns 7 inside the telescopic component are connected by a connecting rod. The connecting rod is movably connected to the bottom wall of the top plate of the adapter housing 2 through two connecting columns. Two cylinders are fixedly connected to the bottom of the connecting rod. The cylinders movably penetrate the top of the piston box 6 and are fixedly connected to the piston plate 601. The inclined side of the second movable block 802 inside the adapter housing 2 is in contact with the roller 702. When the adapter housing 2 is inserted into the track bar 1, the edge of the track bar 1 first contacts and pushes the first movable block 8 and the second movable block 802 to retract inward. When the first moving block 8 moves inward, its inclined side pushes the roller 702, causing the moving column 7 to move downward against the force of the second spring 701. This drives the piston plate 601 to move downward in the piston box 6, compressing the air inside the piston box 6. The compressed air is discharged through the outlet at the bottom of the piston box 6, forming a purging airflow. At the same time, the second moving block 802 is also pushed inward to retract. Its inclined side pushes the corresponding roller 702, which drives another piston assembly to work through the connecting rod, causing the piston plate 601 of the other piston assembly to move upward. The coordinated work of the first and second moving components realizes both blowing and sucking functions.
[0027] In one embodiment of the present invention, a first air guide plate 602 and a second air guide plate 603 are fixedly connected to both sides of the bottom end of the piston housing 6, respectively. The top of the first air guide plate 602 and the second air guide plate 603 have an inclined surface, which forms an angle of 30°-60° with the horizontal plane. The inclination direction of the first air guide plate 602 and the second air guide plate 603 of the suction mechanism is opposite to the inclination direction of the first air guide plate 602 and the second air guide plate 603 of the blowing mechanism. The blowing mechanism guides the airflow generated by the piston assembly to the surface of the conductive strip 101 of the track strip 1. A directional airflow is formed to effectively remove dust from the surface of the conductive strip 101. The suction mechanism draws in the air and dust blown out by the piston assembly of the blowing mechanism. When the piston assembly is reset, the air guide plate of the suction mechanism creates a negative pressure, which draws the dust raised by the blowing mechanism and the residual dust on the surface of the conductive strip 101 into the piston housing 6 for temporary storage, preventing secondary contamination of the conductive strip 101 by dust. This "blow first, then suck" cleaning method ensures that the contact surface between the brush 503 and the conductive strip 101 is clean, greatly reducing the risk of poor contact.
[0028] The working principle and usage process of this invention: When the external power supply is connected, the conductive strip 101 inside the track 1 is energized. First, according to the installation position requirements, the adapter housing 2 is brought close to the track 1. The magnet (not shown in the figure) built into the bottom of the adapter housing 2 generates a magnetic attraction with the magnetic material of the track 1, so that the adapter housing 2 is initially attracted to the track 1, achieving rapid pre-positioning. At this time, the brush 503 is in a retracted state and is detached from the conductive strip 101. The fixing block 502 is also in a retracted state and is not engaged with the fixing groove 102. Therefore, the adapter housing 2 can slide freely on the track 1. The user can slide the camera 4 to a suitable position according to the monitoring requirements without causing friction damage to the conductive strip 101 and the brush 503. When the adapter housing 2 is inserted into the track bar 1, the edge of the track bar 1 first contacts and pushes the moving block 8 and the moving block 802 to retract inward. When the moving block 8 moves inward, its inclined side pushes the roller 702, causing the moving column 7 to move downward against the force of the spring 701, driving the piston plate 601 to move downward in the piston box 6, compressing the air in the piston box 6. The compressed air is guided by the air guide plate 602 and the air guide plate 603 and blown at an angle of 30°-60° onto the surface of the conductive strip 101, forming a directional blowing airflow that effectively cleans the surface of the conductive strip 101. Accumulated dust and particulate matter are simultaneously pushed inward by the moving block 802, which pushes the corresponding roller 702 through its inclined side. This drives another piston assembly to work via a connecting rod, causing the piston plate 601 of the piston assembly to move upward. Its air guide plate forms a negative pressure area, sucking the dust raised by the blowing mechanism and the residual dust on the surface of the conductive strip 101 into the piston box 6 for temporary storage. This "blow first, then suck" cleaning process is completed before the brush 503 contacts the conductive strip 101, ensuring the cleanliness of the contact surface, greatly reducing the risk of poor contact, and laying the foundation for stable power supply. After cleaning, the user pushes the push block 5 to move laterally along the slide. The push block 5 drives the L-shaped rod 501 to move laterally. The L-shaped rod 501 pushes the brush 503 down along the inclined surface of the limit block 504 and down along the bottom end of the L-shaped rod 501, so that the top of the brush 503 is disengaged from the slot of the fixing plate 204. At the same time, the bottom of the brush 503 extends out and is tightly attached to the conductive strip 101 to complete the power supply connection. At this time, the current in the track bar 1 is introduced into the circuit board of the built-in box 202 through the conductive strip 101, the brush 503 and the internal wires. After voltage conversion and stabilization, it is transmitted to the output interface at the bottom of the fixing seat 3 through the flexible cable, and then conducted to the camera 4 through the line to realize the stable power supply of the camera 4. At the same time, the fixing block 502 at the top of the L-shaped rod 501 extends out of the side wall of the adapter housing 2 and inserts into the fixing groove 102 of the track bar 1 to realize the mechanical locking between the adapter housing 2 and the track bar 1, preventing the adapter from falling off due to vibration or external force during use. When the push block 5 moves to the designated position, the limiting component works. The round head of the limiting post 505 is engaged in the groove of the push block 5 under the action of the spring 506, giving a clear feeling of being in place. This keeps the position of the push block 5 stable and prevents the push block 5 from retracting due to vibration, thereby ensuring that the brush 503 always maintains good contact with the conductive strip 101 and the fixing block 502 always maintains reliable engagement with the fixing groove 102. When the position of camera 4 needs to be adjusted, the user pushes the push block 5 in the opposite direction, causing the circular head of the limiting post 505 to disengage from the groove of the push block 5. The L-shaped rod 501 moves in the opposite direction, and the brush 503 rises along the inclined surface of the limiting block 504, retracts to the initial position, and disengages from the conductive strip 101. At the same time, the fixing block 502 retracts and exits from the fixing groove 102, releasing the mechanical lock. At this time, the adapter housing 2 can slide freely on the track 1 again. After moving to the new position, the above operation of pushing the push block 5 is repeated to complete the repositioning and locking. Throughout the entire usage process, each time the adapter housing 2 is inserted into the track bar 1, the blowing and suction mechanisms will automatically perform a cleaning cycle to ensure that the surface of the conductive strip 101 remains clean. This effectively prevents malfunctions such as poor contact, overheating, or power failure caused by dust accumulation, and greatly improves the long-term operational reliability of the system.
