Description

Technical Field

[0001] This utility model relates to the field of rail power supply technology, and in particular to a rail-type power supply device. Background Technology

[0002] In fields such as industrial automation, logistics transportation, and smart warehousing, a large number of electrical devices require stable power supply during movement. Traditional power supply methods face numerous technical bottlenecks. For example, using dragged cables is prone to cable tangling, wear, and even breakage, which not only shortens the cable's lifespan but also poses a short-circuit risk, affecting equipment operational safety. While sliding contact line power supply systems can achieve mobile power supply, the contact line is usually exposed to the external environment, making it susceptible to dust and moisture corrosion, leading to decreased conductivity. Furthermore, its conductive structure lacks effective insulation measures, posing a risk of leakage. In addition, existing track-mounted power supply devices mostly use a single conductive track or a simple contact conductive design, which is insufficient to meet the stable power supply requirements of electrical devices in high-frequency movement and vibration environments. At the same time, the mechanical wear between the conductive components and the track is severe, resulting in high maintenance costs. Therefore, there is an urgent need for a track-mounted power supply device that is structurally reliable, provides stable power supply, and has safe insulation to solve the above-mentioned problems in existing technologies. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a rail-mounted power supply device that can reliably and stably supply power.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A track-mounted power supply device includes a track and a mounting bracket for installing electrical equipment. The track has a groove at its bottom for the mounting bracket to slide. A positive conductive area, insulated from the track, is located on the top of the inner wall of the groove along the sliding direction. A negative conductive area, also insulated from the track, is located on the bottom of the track along the sliding direction. A positive conductive element, electrically connected to the positive conductive area, is located on the top of the mounting bracket. A negative conductive element, electrically connected to the negative conductive area, is located on the lower side wall of the mounting bracket. A first power connection port, electrically connected to an external power source, is located at the end of the track and is electrically connected to both the positive and negative conductive areas.

[0006] Furthermore, both the positive and negative conductive regions include an insulating layer and a conductive copper strip. The conductive copper strip is connected to the track through the insulating layer, and the insulating layer covers the sidewall of the conductive copper strip.

[0007] Furthermore, both the positive and negative conductive regions include an insulating layer and a conductive coating, with the insulating layer disposed between the conductive coating and the track.

[0008] Furthermore, the insulating layer is made of plastic, and its thickness ranges from 0.5mm to 2mm.

[0009] Furthermore, the positive conductive element is a spring-loaded conductive needle, and the negative conductive element is a conductive brush.

[0010] Furthermore, the conductive brush includes a fixing rod connected to the side wall of the fixing frame, and a concave roller mounted on the outer wall of the negative electrode conductive component is installed at the free end of the fixing rod. The inner wall of the concave roller is provided with a conductive brush.

[0011] Furthermore, the spring conductive needle includes a sleeve with an opening at its end, and the sleeve is mounted on the top of the fixing frame. A conductive needle is slidably connected through the opening of the sleeve. A spring is connected between the conductive needle and the bottom of the inner cavity of the sleeve. The conductive needle is electrically connected to the positive terminal of the second power connection port.

[0012] Furthermore, the top of the conductive needle has a rounded structure, and the positive conductive area has a limiting groove that cooperates with the spring conductive needle.

[0013] Furthermore, the cross-sectional shape of the groove is a convex shape with the protrusion facing downwards.

[0014] Furthermore, the mounting bracket is provided with a second power connection port that is electrically connected to the positive and negative conductive components.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention features mutually insulated positive and negative conductive areas along the sliding direction of the track. Corresponding positive and negative conductive components are then installed on the mounting frame. This allows the mounting frame to generate power when in contact with the track, supplying it to the electrical equipment and ensuring uninterrupted power supply during movement. This solves the problems of tangling and wear caused by traditional cable dragging. Furthermore, the insulation of both the positive and negative conductive areas from the track, along with the separation of the positive and negative electrodes, prevents direct contact and short circuits, thus improving power supply safety.

[0023] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0024] Please refer to Figures 1 to 4 The technical solution adopted by this utility model is as follows:

[0025] A track-mounted power supply device includes a track and a mounting bracket for installing electrical equipment. The track has a groove at its bottom for the mounting bracket to slide. A positive conductive area, insulated from the track, is located on the top of the inner wall of the groove along the sliding direction. A negative conductive area, also insulated from the track, is located on the bottom of the track along the sliding direction. A positive conductive element, electrically connected to the positive conductive area, is located on the top of the mounting bracket. A negative conductive element, electrically connected to the negative conductive area, is located on the lower side wall of the mounting bracket. A first power connection port, electrically connected to an external power source, is located at the end of the track and is electrically connected to both the positive and negative conductive areas.

[0026] As can be seen from the above description, the beneficial effects of this utility model are as follows:

[0027] This invention features mutually insulated positive and negative conductive areas along the sliding direction of the track. Corresponding positive and negative conductive components are then installed on the mounting frame. This allows the mounting frame to generate power when in contact with the track, supplying it to the electrical equipment and ensuring uninterrupted power supply during movement. This solves the problems of tangling and wear caused by traditional cable dragging. Furthermore, the insulation of both the positive and negative conductive areas from the track, along with the separation of the positive and negative electrodes, prevents direct contact and short circuits, thus improving power supply safety.

[0028] Furthermore, both the positive and negative conductive regions include an insulating layer and a conductive copper strip. The conductive copper strip is connected to the track through the insulating layer, and the insulating layer covers the sidewall of the conductive copper strip.

[0029] As can be seen from the above description, using copper strips for conductivity can make the conductivity more stable and is suitable for high current scenarios.

[0030] Furthermore, both the positive and negative conductive regions include an insulating layer and a conductive coating, with the insulating layer disposed between the conductive coating and the track.

[0031] As can be seen from the above description, the use of conductive coatings can reduce the production cost of equipment and make the equipment structure compact, making it suitable for lightweight design.

[0032] Furthermore, the insulating layer is made of plastic, and its thickness ranges from 0.5mm to 2mm.

[0033] As can be seen from the above description, the conductive area is isolated from the main track to prevent leakage, while also withstanding the high-temperature environment during equipment operation, thus improving safety and durability.

[0034] Furthermore, the positive conductive element is a spring conductive needle, and the spring conductive needle includes a sleeve with an opening at the end, and the sleeve is installed on the top of the fixing frame. The conductive needle is slidably connected through the opening of the sleeve, and a spring is connected between the conductive needle and the bottom of the inner cavity of the sleeve. The conductive needle is electrically connected to the positive terminal of the second power connection port. The negative conductive element is a conductive brush, and the conductive brush includes a fixing rod connected to the side wall of the fixing frame. A concave roller is installed at the free end of the fixing rod and rests on the outer wall of the negative conductive element. A conductive brush is provided on the inner wall of the concave roller.

[0035] As can be seen from the above description, the elasticity of the spring conductive needle allows it to press against the positive conductive area, ensuring that the electrical connection is maintained throughout the sliding process and adapting to vibration or displacement scenarios. Meanwhile, the conductive brush, with its concave rollers, can fit against the negative conductive area and reduce wear through rolling friction, extending the life of the conductive components and ensuring stable conductivity.

[0036] Furthermore, the top of the conductive needle has a rounded structure, and the positive conductive area has a limiting groove that cooperates with the spring conductive needle.

[0037] As can be seen from the above description, the round head structure can reduce the friction between the conductive needle and the positive conductive area, while the setting of the limiting groove ensures that the conductive needle will not tilt.

[0038] Furthermore, the cross-sectional shape of the groove is a convex shape with the protrusion facing downwards.

[0039] As can be seen from the above description, the fixed frame can slide along the track while limiting its lateral displacement, ensuring the stability of the electrical equipment when it moves, which is suitable for scenarios that require dynamic power supply.

[0040] Furthermore, the mounting bracket is provided with a second power connection port that is electrically connected to the positive and negative conductive components.

[0041] As can be seen from the above description, the first power connection port at the end of the track is directly connected to an external power source, and the second power connection port on the mounting bracket is connected to the electrical equipment, forming a complete circuit, simplifying the wiring process, and facilitating quick installation and maintenance.

[0042] Please refer to Figures 1 to 4 As shown, Embodiment 1 of this utility model is as follows:

[0043] Please refer to Figure 1 A track-mounted power supply device includes a track 1 and a mounting bracket 2 for mounting electrical equipment. The bottom of the track 1 has a groove 3 for the mounting bracket 2 to slide. The top of the inner wall of the groove 3 is provided with a positive conductive area 4 that is insulated from the track 1 along the sliding direction. The bottom of the track 1 is provided with a negative conductive area 5 that is insulated from the track 1 along the sliding direction. The top of the mounting bracket 2 is provided with a positive conductive element 6 that is electrically connected to the positive conductive area 4. The lower side wall of the mounting bracket 2 is provided with a negative conductive element 7 that is electrically connected to the negative conductive area 5. The end of the track 1 is provided with a first power connection port 8 that is electrically connected to an external power source, and the first power connection port 8 is electrically connected to both the positive conductive area 4 and the negative conductive area 5.

[0044] Please refer to Figure 1 and Figure 2 In this embodiment, both the positive conductive region 4 and the negative conductive region 5 include an insulating layer and a conductive copper strip. The conductive copper strip is connected to the track 1 through the insulating layer, and the insulating layer covers the sidewall of the conductive copper strip.

[0045] Please refer to Figure 1 and Figure 2 In this embodiment, both the positive conductive region 4 and the negative conductive region 5 include an insulating layer and a conductive coating, and the insulating layer is disposed between the conductive coating and the track 1. In this embodiment, the insulating layer is made of a high-temperature resistant and high-insulation plastic material, and the thickness of the insulating layer ranges from 0.5 to 2 mm.

[0046] Please refer to Figure 3 and Figure 4In this embodiment, the positive conductive element 6 is a spring 63 and a conductive needle 62, and the spring 63 and conductive needle 62 include a sleeve 61 with an opening at the end, and the sleeve 61 is installed on the top of the fixing frame 2. The conductive needle 62 is slidably connected through the opening of the sleeve 61. A spring 63 is connected between the conductive needle 62 and the bottom of the inner cavity of the sleeve 61. The conductive needle 62 is electrically connected to the positive terminal of the second power connection port. The top of the conductive needle 62 has a round head structure. The positive conductive area 4 has a limiting groove that cooperates with the spring 63 and conductive needle 62. The negative conductive element 7 is a conductive brush. The conductive brush includes a fixing rod 71 connected to the side wall of the fixing frame 2. A concave roller 72 is installed at the free end of the fixing rod 71 and rests on the outer wall of the negative conductive element 7. A conductive brush 73 is provided on the inner wall of the concave roller 72.

[0047] Please refer to Figure 2 In this embodiment, the cross-sectional shape of the groove 3 is a convex shape with the protrusion facing downwards.

[0048] Please refer to Figure 4 In this embodiment, the fixing frame 2 is provided with a second power connection port that is electrically connected to the positive conductive element 6 and the negative conductive element 7.

[0049] In this embodiment, the electrical equipment is installed on the mounting bracket 2 by means of bolts or clips.

[0050] In this embodiment, the first power connection port 8 is electrically connected to both the positive conductive area and the negative conductive area via a line, and the second power connection port is electrically connected to both the positive conductive component and the negative conductive component via a line.

[0051] The working process of the aforementioned power supply track 1 is as follows:

[0052] When using this power supply track 1, the electrical equipment is installed at the bottom of the mounting bracket 2 (using bolts or clips for installation and fixation). Then, the power cord of the electrical equipment is inserted into the second power connection port, and the external power supply is turned on. The external power supply supplies power to the positive conductive area 4 and the negative conductive area 5 in the track 1 through the first power connection port 8. The positive conductive area 4 supplies power to the electrical equipment through the conductive pin 62, and the negative conductive area 5 supplies power to the electrical equipment through the conductive brush, so that the electrical equipment achieves circuit conduction and forms a complete circuit for the use of the electrical equipment.

[0053] If vibration occurs during the sliding of the fixed block, the spring 63 at the bottom of the conductive needle 62 can keep the conductive needle 62 pressed against the positive conductive area 4, while the conductive brush 73 of the conductive brush can also keep pressed against the negative conductive area 5 due to the material. At the same time, the concave roller 72 can make the conductive brush 73 fully contact the negative conductive area 5, ensuring the stable power supply of the electrical equipment during the sliding process.

[0054] In summary, the track-type power supply device provided by this utility model, by setting mutually insulated positive and negative conductive areas on the track in the sliding direction, and then setting corresponding positive and negative conductive components on the fixing frame, enables the fixing frame to generate power when in contact with the track and supply power to the electrical equipment, ensuring uninterrupted power supply to the equipment during movement. This solves the problems of entanglement and wear caused by traditional cable dragging. At the same time, both the positive and negative conductive areas are insulated from the track, and the separation of positive and negative electrodes avoids short circuits caused by direct contact between the positive and negative electrodes, improving power supply safety. Furthermore, the track-type design can be extended or spliced ​​as needed to adapt to different lengths of working areas, and the fixing frame can carry multiple electrical devices, improving system flexibility. The insulation layer and the separate conductive area design reduce the risk of short circuits, and the spring and roller structure reduces mechanical wear, making it suitable for high-frequency application scenarios such as industrial automation and logistics transportation.
