Description

Technical Field

[0001] This invention relates to the field of lighting equipment technology, and more specifically, to a flexible track lighting device. Background Technology

[0002] Flexible track lighting equipment uses flexible silicone or polymer materials as the main body of the track, with built-in conductive copper strips and flexible circuit boards. It is combined with sliding magnetic or snap-on lamp modules to form the core structure. Its working principle is to use the flexible track's bendability to adapt to different installation surfaces. The conductive copper strips provide stable power to the moving lamps. The lamps can be adjusted in position and angle by sliding to achieve precise light control. This equipment is widely used in places where flexible lighting layout is required. It can meet the lighting function while adapting to various spatial shapes, enhancing the visual hierarchy and design aesthetics of the environment.

[0003] For example, Chinese patent CN113390035A discloses a flexible track lighting device, including a track body made of flexible insulating material and several lighting components suspended on the track body. A conductive skeleton made of ferromagnetic material is inserted inside the track body. Each lighting component is provided with a power-taking device that can pierce the outer skin of the track body and contact the conductive skeleton at one end for supplying power to the lighting component. This provides a method of obtaining power by piercing the outer skin of the track body and contacting the conductive skeleton with the power-taking device. Compared with traditional rigid tracks where the conductive sheet is embedded in an open groove, this method reduces the operator's contact with exposed cables during installation. The flexible track can be bent at will to make various shapes, making it more applicable to complex installation scenarios and easier to transport and install.

[0004] The aforementioned patent utilizes conductive copper needles to pierce the outer skin of the track body to extract electricity. However, in actual working scenarios, the conductive copper needles are quite sharp in order to successfully pierce the outer skin of the track body, resulting in high resistance at the contact point between the conductive copper needle and the conductive frame, causing significant heat generation. Moreover, the ends of the conductive copper needles are prone to wear under vibration conditions, leading to poor contact between the conductive copper needles and the conductive frame, which affects the operation of the equipment. Therefore, we propose a flexible track lighting device. Summary of the Invention

[0005] This invention provides a flexible track lighting device that solves the problems mentioned in the background art, which uses conductive copper needles to pierce the outer skin of the track body to extract electricity. However, in actual working scenarios, in order to successfully pierce the outer skin of the track body, the conductive copper needles are relatively sharp, resulting in high resistance at the contact point between the conductive copper needle and the conductive frame, and significant heat generation. Moreover, the ends of the conductive copper needles are prone to wear under vibration, leading to poor contact between the conductive copper needle and the conductive frame, which affects the operation of the device.

[0006] To achieve the above objectives, this solution provides a flexible track lighting device, including a flexible track, on which a movable sleeve for mounting lamps is slidably installed. A conductive sheet is provided inside the flexible track, and a through groove is opened on the flexible track. A vertical rod is slidably installed in the through groove, and the vertical rod is slidably inserted into the movable sleeve. A first telescopic rod is provided at the bottom end of the vertical rod, and a conductive block is installed at the end of the first telescopic rod near the conductive sheet.

[0007] The flexible track has a pair of clamps for fixing the conductive sheet inside. An abutment strip is installed on the clamp at the bottom. The edges of the abutment strip are rounded. An abutment rod is installed at the bottom of the first telescopic rod. When the abutment rod abuts against the abutment strip, the conductive block moves away from the conductive sheet.

[0008] Optionally, a first sleeve is installed at the bottom end of the vertical rod, and the first telescopic rod is slidably installed in the first sleeve. A compression spring is provided inside the first sleeve, and the other end of the compression spring abuts against the first telescopic rod.

[0009] Optionally, the top of the vertical rod is provided with a pressing plate for easy pressing, a return spring is sleeved on the vertical rod, the other end of the return spring is connected to the movable sleeve, and a pair of locking strips are also provided on the vertical rod, the locking strips being slidably engaged with the movable sleeve.

[0010] Optionally, a limiting plate is fixedly installed on the vertical rod. The limiting plate is located inside the movable sleeve, and several rollers are installed on both the limiting plate and the movable sleeve on the side closest to the flexible track.

[0011] Optionally, a horizontal bar is installed on the vertical bar, and a movable rod is provided at the other end of the horizontal bar. Several U-shaped card seats are equidistantly installed on the side of the card plate located above. Under normal conditions, the movable rod is located in the groove of the U-shaped card seat.

[0012] Optionally, a brush plate is installed at the bottom of the movable rod, the brush plate is in contact with the conductive sheet, and a pair of brush plates are provided, with the pair of brush plates located on both sides of the conductive block.

[0013] Optionally, a second sleeve is installed on the crossbar, and a second telescopic rod is slidably installed in the second sleeve. The movable rod is connected to the second telescopic rod, and a buffer spring is provided inside the second sleeve. The other end of the buffer spring is connected to the second telescopic rod.

[0014] Optionally, a hoop is installed on one end of the second telescopic rod near the movable rod, the movable rod is slidably connected to the hoop, a reciprocating spring is sleeved on the movable rod, and the other end of the reciprocating spring is connected to the brush plate.

[0015] Optionally, the bottom end of the U-shaped card holder is provided with a protrusion, and when the movable rod moves horizontally, the top end of the movable rod intermittently abuts against the protrusion.

[0016] Optionally, the bottom of the flexible track is provided with a ash discharge trough for discharging debris, and multiple ash discharge troughs are provided and distributed at equal intervals.

[0017] Through the above technical solution, the flexible track lighting equipment provided by this solution, under normal conditions, uses a compression spring to apply pressure to the No. 1 telescopic rod, so that the conductive block and the conductive sheet are in close contact. When moving the lamp, the pressing plate is pressed down, and the vertical rod moves down, so that the abutting rod on the No. 1 telescopic rod abuts against the abutting strip. When the abutting rod and the abutting strip abut against each other, the conductive block moves away from the conductive sheet. Then the moving sleeve moves. During the movement of the moving sleeve, the conductive block and the conductive sheet do not come into contact, which prevents the conductive block from rubbing against the conductive sheet when it moves, thus increasing the service life of this device.

[0018] When the lamp is in static use, this device uses a U-shaped retainer to limit the movement of the movable rod, preventing movement of the movable rod, vertical rod, moving sleeve, and lamp itself. This helps reduce frictional loss between the conductive block and the conductive sheet. During lamp movement, pressing down on the pressing plate moves the vertical rod downwards, causing the movable rod to move out of the U-shaped retainer, allowing for smooth movement. Furthermore, after the movable rod moves out of the U-shaped retainer, it continuously abuts against the protrusion at the bottom of the retainer. This contact causes the movable rod to move the brush plate downwards and compresses the reciprocating spring. When the movable rod passes the protrusion, the reciprocating spring releases, and the movable rod and the moving brush plate quickly move upwards. Therefore, during lamp movement, the brush plate cleans impurities from the surface of the conductive sheet in front of the conductive block. Simultaneously, the brush plate can move up and down simultaneously while moving horizontally, improving the cleaning effect on the conductive sheet. This ensures a tighter contact between the conductive block and the conductive sheet upon re-contact, reducing the occurrence of poor contact and improving the reliability of the device.

[0019] Other features and advantages of this solution will be described in detail in the following detailed implementation section. Attached Figure Description

[0030] To make the aforementioned objectives, features, and advantages of this solution more apparent and understandable, the specific embodiments of this solution are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this solution. However, this solution can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this solution. Therefore, this solution is not limited to the specific embodiments disclosed below.

[0031] In the description of this solution, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this solution and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this solution. The terms "first" and "second" used are to distinguish one element from another and do not have sequential or importance implications. Furthermore, in the following description, when referring to the accompanying drawings, the same reference numerals in different drawings indicate the same or similar elements, which will not be repeated here.

[0032] In this solution, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this solution based on the specific circumstances.

[0033] According to some embodiments of this solution, a flexible track lighting device is provided, for reference. Figures 1 to 8 As shown, the flexible track lighting device includes a flexible track 101, on which a movable sleeve 102 for mounting lamps is slidably installed. A conductive sheet 105 is provided inside the flexible track 101 and is electrically connected to the lamps. A through groove 103 is provided on the flexible track 101, and a vertical rod 202 is slidably installed in the through groove 103. The vertical rod 202 is slidably inserted into the movable sleeve 102. A first telescopic rod 208 is provided at the bottom of the vertical rod 202. A conductive block 209 is installed at the end of the first telescopic rod 208 near the conductive sheet 105. A pair of clamping plates 106 for fixing the conductive sheet 105 are provided inside the flexible track 101. An abutment strip 211 is installed on the clamping plate 106 at the bottom. The edges of the abutment strip 211 are rounded. An abutment rod 210 is installed at the bottom of the first telescopic rod 208. When the abutment rod 210 abuts against the abutment strip 211, the conductive block 209 moves away from the conductive sheet 105.

[0034] Thus, under normal conditions, the conductive block 209 at the end of the first telescopic rod 208 is in contact with the conductive sheet 105. When it is necessary to move the position of the lamp, press down on the vertical rod 202 so that the abutment rod 210 on the first telescopic rod 208 abuts against the abutment strip 211. When the abutment rod 210 abuts against the abutment strip 211, the conductive block 209 moves away from the conductive sheet 105. Then, the moving sleeve 102 is moved. During the movement of the moving sleeve 102, the conductive block 209 does not contact the conductive sheet 105, preventing friction from the conductive block 209 on the conductive sheet 105 when it moves, thus increasing the service life of the device.

[0035] For details, see Figure 4 A first sleeve 207 is installed at the bottom of the vertical rod 202. A first telescopic rod 208 is slidably installed in the first sleeve 207. A compression spring 212 is installed inside the first sleeve 207. The other end of the compression spring 212 abuts against the first telescopic rod 208. The compression spring 212 applies pressure to the first telescopic rod 208, so that the conductive block 209 and the conductive sheet 105 are in close contact.

[0036] The vertical rod 202 has a pressing plate 201 at its top for easy pressing, and a return spring 203 is sleeved on the vertical rod 202. The other end of the return spring 203 is connected to the movable sleeve 102. The vertical rod 202 is also equipped with a pair of locking strips 204, which are slidably engaged with the movable sleeve 102. Therefore, the vertical rod 202 can only move up and down, preventing the vertical rod 202 from deflecting during the pressing process and ensuring that the first telescopic rod 208 at the bottom of the vertical rod 202 is always aligned with the conductive sheet 105.

[0037] Additionally, see Figure 2 , Figure 3 A limiting plate 206 is fixedly installed on the vertical rod 202. The limiting plate 206 is located inside the movable sleeve 102. Several rollers 205 are installed on both the limiting plate 206 and the side of the movable sleeve 102 closest to the flexible track 101. The setting of the rollers 205 helps to reduce the frictional resistance between the movable sleeve 102 and the flexible track 101, ensuring that the movable sleeve 102 moves smoothly.

[0038] It should be noted that, since the shape of the flexible track 101 can be bent freely, in order to ensure that the moving sleeve 102 can pass smoothly through the bent part of the flexible track 101, an appropriate gap should be left between the moving sleeve 102 and the flexible track 101. In addition, the contact end of the lamp includes a positive pole and a negative pole. Therefore, a pair of conductive blocks 209 and conductive sheets 105 should be provided in this device. The pair of conductive blocks 209 are respectively connected to the positive pole and the negative pole of the lamp, and the pair of conductive blocks 209 and the pair of conductive sheets 105 are respectively provided.

[0039] Through the above technical solution, the flexible track lighting equipment provided by this solution, under normal use, uses the compression spring 212 to apply pressure to the first telescopic rod 208, making the conductive block 209 and the conductive sheet 105 in close contact. When moving the lamp, pressing down the pressing plate 201 causes the vertical rod 202 to move down, causing the abutment rod 210 on the first telescopic rod 208 to abut against the abutment strip 211. When the abutment rod 210 abuts against the abutment strip 211, the conductive block 209 moves away from the conductive sheet 105. Then, the moving sleeve 102 is moved. During the movement of the moving sleeve 102, the conductive block 209 moves away from the conductive sheet 105. The conductive block 209 does not contact the conductive sheet 105 to prevent friction on the conductive sheet 105 when the conductive block 209 moves, thus increasing the service life of the device. Therefore, it solves the problem of existing technology that uses conductive copper needles to pierce the outer skin of the track body to extract electricity. However, in actual working scenarios, in order to successfully pierce the outer skin of the track body, the conductive copper needles are relatively sharp, which results in high resistance at the contact point between the conductive copper needle and the conductive frame, and significant heat generation. Moreover, the ends of the conductive copper needles are prone to wear under vibration, leading to poor contact between the conductive copper needle and the conductive frame, which affects the operation of the equipment.

[0040] In some implementations of this solution, reference is made to Figure 6 , Figure 7 As shown, a horizontal bar 307 is installed on the vertical bar 202, and a movable bar 302 is provided at the other end of the horizontal bar 307. Several U-shaped brackets 304 are equidistantly installed on the side of the upper bracket 106. Under normal conditions, the movable bar 302 is located in the groove of the U-shaped bracket 304. When the lamp is static, the U-shaped bracket 304 is used to limit the movable bar 302 to prevent the movable bar 302, the vertical bar 202, the movable sleeve 102 and the lamp from moving. When the lamp needs to be moved, the pressing plate 201 is pressed down, the vertical bar 202 moves down, and the movable bar 302 moves out of the U-shaped bracket 304, so that it can move smoothly.

[0041] In addition, a brush plate 301 is installed at the bottom of the movable rod 302. The brush plate 301 is in contact with the conductive sheet 105. A pair of brush plates 301 are provided, and the pair of brush plates 301 are located on both sides of the conductive block 209.

[0042] Please refer to Figure 4 A second sleeve 306 is installed on the crossbar 307. A second telescopic rod 308 is slidably installed in the second sleeve 306. The movable rod 302 is connected to the second telescopic rod 308. A buffer spring 309 is installed inside the second sleeve 306. The other end of the buffer spring 309 is connected to the second telescopic rod 308. The second telescopic rod 308 is designed to prevent the device from getting stuck when passing through the bending part of the flexible track 101. Specifically, if the space in front of the second telescopic rod 308 narrows during the movement, the second telescopic rod 308 will retract into the second sleeve 306 to ensure the normal movement of the second telescopic rod 308.

[0043] Among them, the second telescopic rod 308 is equipped with a hoop 303 at one end near the movable rod 302. The movable rod 302 is slidably connected to the hoop 303. A reciprocating spring 310 is sleeved on the movable rod 302. The other end of the reciprocating spring 310 is connected to the brush plate 301.

[0044] Additionally, see Figure 8 The bottom of the U-shaped card holder 304 is provided with a protrusion 305. When the movable rod 302 moves horizontally, the top of the movable rod 302 intermittently contacts the protrusion 305.

[0045] Additionally, please refer to Figure 6 The bottom of the flexible track 101 is provided with a ash discharge trough 104 for discharging debris. Multiple ash discharge troughs 104 are provided and are distributed at equal intervals.

[0046] Therefore, when the lamp is in static use, the U-shaped bracket 304 limits the movement of the movable rod 302, preventing the movable rod 302, the vertical rod 202, the movable sleeve 102, and the lamp from moving. This helps reduce frictional loss between the conductive block 209 and the conductive sheet 105. During the movement of the lamp, pressing down on the pressing plate 201 causes the vertical rod 202 to move downwards, and the movable rod 302 moves out of the U-shaped bracket 304, thus allowing for smooth movement. Furthermore, after the movable rod 302 moves out of the U-shaped bracket 304, it continuously abuts against the protrusion 305 at the bottom of the U-shaped bracket 304. When the movable rod 302 abuts against the protrusion 305, the movable rod... The movable rod 302 drives the brush plate 301 to move downwards, and compresses the reciprocating spring 310. When the movable rod 302 passes the protrusion 305, the reciprocating spring 310 is released, and the movable rod 302 and the movable brush plate 301 move upwards quickly. Therefore, during the movement of the lamp, the brush plate 301 cleans the impurities on the surface of the conductive sheet 105 in front of the conductive block 209. At the same time, the brush plate 301 can move up and down reciprocally while moving horizontally, which improves the cleaning effect of the brush plate 301 on the conductive sheet 105. When the conductive block 209 and the conductive sheet 105 come into contact again, they can make tight contact, reduce the occurrence of poor contact, and improve the reliability of the device.

[0047] The preferred embodiments of this solution have been described in detail above with reference to the accompanying drawings. However, this solution is not limited to the specific details in the above embodiments. Within the scope of the technical concept of this solution, various simple modifications can be made to the technical solution, and these simple modifications all fall within the protection scope of this solution.

[0048] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this solution will not describe the various possible combinations separately.

[0049] Furthermore, various implementations of this solution can be combined in any way, as long as they do not violate the spirit of this solution, they should also be regarded as the content disclosed in this solution.
