Description

Technical Field

[0001] This utility model relates to the field of LED strip technology, and in particular to a magnetic LED strip docking mechanism and lighting device. Background Technology

[0002] As a flexible and extendable lighting device, LED strips are commonly used in indoor and outdoor decoration, architectural outline lighting, and landscape lighting. The strip itself is usually long and can be up to two meters long.

[0003] Currently, LED strip lights are typically connected to a socket during use. This method requires a complex socket and plug structure between the LED strip and the power source. When installing or removing the LED strip, due to its physical properties and fragility, it is often difficult for a person to hold the strip with one hand and mechanically plug and unplug it. Usually, one person needs to hold the strip while another performs the mechanical plugging and unplugging to ensure safe power control. Therefore, manual plugging and unplugging is inconvenient and hinders the application of LED strip lights in scenarios requiring rapid installation and maintenance. Utility Model Content

[0011] In some embodiments, a first spring and a second spring are further included, which are disposed inside the groove and abut against the magnetic male seat body; the first spring is sleeved on the first vertical portion, and the second spring is sleeved on the second vertical portion.

[0012] In some embodiments, a third connecting hole and a fourth connecting hole are provided on opposite sides of the first end face of the fixing base; the third connecting hole is directly opposite the first connecting hole, and the fourth connecting hole is directly opposite the second connecting hole.

[0013] In some embodiments, the connecting component includes a first connector and a second connector; the first connector passes through the first connecting hole and the third connecting hole in sequence, and the second connector passes through the second connecting hole and the fourth connecting hole in sequence.

[0015] Compared with the prior art, the magnetic LED strip docking mechanism and lighting device of this utility model have the following advantages: In this embodiment of the invention, a first wire is pre-laid on the light strip, and the first wire is electrically connected to a first metal protrusion on the magnetic male connector body located at the bottom of the light strip.

Its structure is simple, disassembly is convenient, and the convenience of using the light strip is improved. Attached Figure Description

Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature, and in this description of the utility model, "at least" means one or more, unless otherwise explicitly specified.

[0021] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] See again Figures 1 to 5 This utility model provides a magnetic LED strip docking mechanism, comprising: an LED strip 100 with a first conductor on it; a magnetic male connector body 200 disposed at the bottom of the LED strip 100, the magnetic male connector body 200 having a first metal protrusion 210 electrically connected to the first conductor; and a magnetic female connector body 300 disposed on the end face of the magnetic male connector body 200 facing away from the LED strip 100 and magnetically attracted to the magnetic male connector body 200, the magnetic female connector body 300 having a first through hole 310 on the end face facing away from the magnetic male connector body 200, the magnetic female connector body 300 having a second metal protrusion 320 electrically connected to a power source on the end face of the magnetic female connector body 300 facing away from the magnetic male connector body 200, the inner wall of the first through hole 310 having a conductive layer electrically connected to the second metal protrusion 320, and the first metal protrusion 210 being inserted into the first through hole 310 and contacting the conductive layer.

[0023] In this embodiment, the first conductor (not shown in the figure) serves as a current transmission path and is electrically connected to the light strip 100, thereby transmitting the current passing through the first metal protrusion 210 to the light strip 100 through the first conductor. The magnetic male connector body 200 is provided with the first metal protrusion 210, wherein the first metal protrusion 210 (first upper cylinder 211) located on the first end face of the magnetic male connector body 200 is connected to the bottom of the light strip 100 through the first conductor. The magnetic female connector body 300 has a first through hole 310 and a second metal protrusion 320 electrically connected to a power source on opposite side end faces, and the second metal protrusion 320 is electrically connected to the conductive layer (not shown in the figure) on the inner wall of the first through hole 310.

[0024] When the magnetic male connector body 200 and the magnetic female connector body 300 are magnetically connected, the first metal protrusion 210 (specifically the first lower cylinder 212) on the second end face of the magnetic male connector body 200 is inserted into the first through hole 310 and contacts the conductive layer. At this time, the current transmitted from the second metal protrusion 320 is transmitted through the conductive layer on the first through hole 310 to the first metal protrusion 210, and then through the first metal protrusion 210 to the first wire electrically connected to it, and then through the first wire to the light strip 100, thereby energizing the light strip 100 and making it light up. That is, when the magnetic female connector body 300 and the magnetic male connector body 200 are magnetically connected, the current circuit of the light strip 100 is connected, and the light strip 100 is energized.

[0025] When the magnetic male connector body 200 and the magnetic female connector body 300 are not magnetically connected (i.e., not directly in contact in space), the first metal protrusion 210 (specifically the first lower cylinder 212) on the second end face of the magnetic male connector body 200 does not pass through the first through hole 310 and does not contact the conductive layer. At this time, the current transmitted from the second metal protrusion 320 cannot be transmitted through the conductive layer to the first metal protrusion 210, nor can it be transmitted through the first metal protrusion 210 to the first wire. As a result, no current flows through the LED strip 100, and the LED strip 100 cannot be powered on and illuminated. That is, when the magnetic female connector body 300 and the magnetic male connector body 200 are not magnetically connected, the current circuit of the LED strip 100 is not connected, and the LED strip 100 is not powered on and does not illuminate. In this way, when installing and removing the LED strip 100, users do not need to perform manual mechanical plugging and unplugging operations. They can simply connect and disconnect the electrical components using magnetic attraction. Its simple structure and easy disassembly improve the convenience of using the LED strip 100.

[0026] It should be noted that the first end face of the magnetic male connector body 200 is opposite to the second end face of the magnetic male connector body 200, and the first end face of the magnetic male connector body 200 is the end face facing the bottom of the light strip 100.

[0027] Specifically, the light strip 100 includes a flexible light strip body and multiple light-emitting diode (LED) light-emitting units spaced apart within the light strip body. Each LED light-emitting unit is electrically connected in sequence via a first wire. The two ends of the first wire extend to the ends of the flexible light strip body and are electrically connected to a first metal protrusion 210 on the magnetic male connector body 200 (specifically, the first wire can be fixed to the first metal protrusion 210 by welding), ensuring that the current flowing through the first metal protrusion 210 can be stably transmitted to the LED light-emitting unit through the first wire.

[0028] The number of light strips 100 can be set according to actual needs. If more than one light strip 100 is set, the multiple light strips 100 are connected by a first wire, thereby realizing the circuit connection of the light-emitting units in each light strip 100.

[0029] Both the magnetic male connector body 200 and the magnetic female connector body 300 can be made of insulating material. At least one first magnet (such as a neodymium iron boron magnet) is embedded in the end face of the magnetic male connector body 200 facing the magnetic female connector body 300. Correspondingly, at least one second magnet (such as a neodymium iron boron magnet) is embedded in the end face of the magnetic female connector body 300 facing the magnetic male connector body 200. The first and second magnets are positioned opposite each other and have opposite polarities, allowing the magnetic male connector body 200 and the magnetic female connector body 300 to be magnetically attracted and fixed together.

[0030] Both the first metal protrusion 210 and the second metal protrusion 320 can be configured as cylindrical structures. They can be made of metals with good electrical conductivity (such as brass or phosphor bronze) by turning or stamping, and their surfaces can be plated with gold or tin to enhance corrosion resistance and electrical conductivity.

[0031] The diameter and height of the first metal protrusion 210 and the second metal protrusion 320 can be set according to actual needs. For example, the diameter can be set to 2 to 3 millimeters (mm), and the height to 5 to 8 millimeters. The number of first metal protrusions 210 is consistent with the number of cores of the first conductor, so that the electrical path is complete and the current path is complete. For example, if the first conductor is a three-core conductor, then three first metal protrusions 210 are set to correspond to the three cores of the first conductor, respectively. The three cores can be live wire, neutral wire, and ground wire, or positive terminal, negative terminal, and control signal line, depending on the power supply and control method of the light strip 100.

[0032] The ratio of the number of the second metal protrusion 320, the first through hole 310, and the first metal protrusion 210 is 1:1:1. This allows for a one-to-one correspondence of circuit channels, ensuring the integrity and safety of electrical functions while avoiding interference or short circuits between multiple channels. It also simplifies structural design and assembly, improving the reliability and versatility of the device. Furthermore, the second metal protrusion 320, the first through hole 310, and the first metal protrusion 210 are coaxially arranged in the vertical direction. This facilitates the smooth insertion of the first metal protrusion 210 into the first through hole 310 during magnetic attraction, ensuring reliable contact with the conductive layer within the first through hole 310 and guaranteeing stable current transmission. Moreover, this coaxial structure prevents misalignment or jamming during insertion, increasing the success rate of magnetic assembly and making the fit between the male and female connectors more compact, reducing the structural space occupancy.

[0033] The first metal protrusion 210 can be connected to the first wire by welding or crimping, and is used to introduce the electrical signal of the conductive layer on the first through hole 310 into the first wire. The diameter of the first through hole 310 can be 0.1-0.2 mm larger than the diameter of the first metal protrusion 210, so that the first metal protrusion 210 can be smoothly inserted into the first through hole 310 during magnetic attraction. The depth of the first through hole 310 matches the height of the first lower cylinder 212.

[0034] In one embodiment, if both the magnetic male connector body 200 and the magnetic female connector body 300 are made of insulating material, a conductive layer (such as nickel plating / gold plating) can be provided on the inner wall of the first through hole 310 in order to make the circuit connected during magnetic insertion. The conductive layer is electrically connected to the second metal protrusion 320 through the solder joint / wire at the bottom or side wall of the first through hole 310, so that the first metal protrusion 210 contacts the conductive layer and conducts electricity upon insertion.

[0035] Specifically, when power is required, the magnetic male connector body 200 and the magnetic female connector body 300 are aligned and tightly attracted under magnetic force. At this time, the first lower cylinder 212 in the first metal protrusion 210 is fully inserted into the first through hole 310 and contacts the conductive metal layer on the inner wall of the through hole, forming a conductive path. External power is transmitted to the LED light-emitting unit of the light strip 100 through the second metal protrusion 320, the conductive layer, the first metal protrusion 210, and the first wire, so that the light strip 100 is lit. When power is cut off, a pulling force greater than the magnetic attraction force is applied to separate the two. The first lower cylinder 212 in the first metal protrusion 210 disengages from the first through hole 310, the conductive path is broken, and the LED light-emitting unit stops working.

[0036] In another embodiment, if the magnetic male connector body 200 and the magnetic female connector body 300 are made of insulating material, a conductive spring contact or a conductive sleeve or other conductive wire or component can be embedded in the first through hole 310 to ensure circuit continuity during magnetic insertion. Taking the conductive sleeve as an example, the inner end of the conductive sleeve (that is, the end embedded inside the magnetic female connector body 300) is electrically connected to the second metal protrusion 320 (specifically, it can be a solder joint, a crimping joint, or direct contact with the second metal protrusion 320), and the outer end (that is, the end facing the first lower cylinder 212) is compressed and contacted when the first lower cylinder 212 in the first metal protrusion 210 is inserted, thereby achieving reliable circuit continuity.

[0037] Specifically, the second metal protrusion 320 serves as a power input terminal, which is electrically connected to the conductive component at the first through hole 310 via an internal conductive line. When the magnetic male connector body 200 and the magnetic female connector body 300 are aligned and magnetically attracted to each other, the first lower cylinder 212 in the first metal protrusion 210 inserts into the corresponding first through hole 310 and forms electrical contact with the conductive component inside the first through hole 310, thereby establishing a conductive path from the second metal protrusion 320 through the internal conductive line or conductive component of the magnetic female connector body 300, the first metal protrusion 210 to the light strip 100, causing the light strip 100 to be energized and emit light. When an external force is applied to separate the magnetic male connector body 200 from the magnetic female connector body 300, the first lower cylinder 212 in the first metal protrusion 210 exits from the first through hole 310, the electrical connection is broken, and the light strip 100 is immediately de-energized.

[0038] In one embodiment, such as Figure 2As shown, the first metal protrusion 210 includes a first upper cylinder 211 and a first lower cylinder 212 coaxial with the first upper cylinder 211 in the vertical direction; the first upper cylinder 211 is located on the end face of the magnetic male base body 200 facing the light strip 100, and the first upper cylinder 211 is electrically connected to the first wire; the first lower cylinder 212 is inserted into the first through hole 310 and contacts the conductive layer.

[0039] In this embodiment, the first metal protrusion 210 provided on the magnetic male connector body 200 serves as a complete (or integrally formed) conductive component, comprising a first upper cylinder 211 located on the side facing the light strip 100 and a first lower cylinder 212 located on the side facing away from the light strip 100, both maintaining a coaxial structure in the vertical direction. Specifically, during the injection molding of the magnetic male connector body 200, the conductive component can be pre-embedded in the corresponding position of the injection mold (the corresponding position is, for example, the middle of the magnetic male connector body 200), so that the injection-molded magnetic male connector body 200 reliably covers and fixes the conductive component.

[0040] More specifically, the first upper cylinder 211 can be configured as a cylindrical structure, located on the end face of the magnetic male base body 200 facing the light strip 100. A wire welding groove is provided at the top of the first upper cylinder 211. The width of the groove matches the diameter of the first wire core. After stripping, the first wire core is inserted into the welding groove, and electrical connection is achieved through soldering. The surface of the welding point needs to be covered with insulating heat-shrink tubing. One end of the heat-shrink tubing is tightly fitted to the root of the first upper cylinder 211, and the other end extends into the wire insulation layer inside the light strip 100 to ensure insulation of the welding point.

[0041] The first lower cylinder 212 can also be a cylindrical structure, located on the end face of the magnetic male connector body 200 facing away from the light strip 100, integrally formed with the first upper cylinder 211 and coaxial. The outer surface of the first lower cylinder 212 is tin-plated to improve conductivity and oxidation resistance. The top of the first lower cylinder 212 can be set as a rounded corner structure to improve the smoothness of insertion with the first through hole 310.

[0042] In this way, the first upper cylinder 211 achieves a stable connection with the first wire on the light strip 100, while the first lower cylinder 212 achieves a reliable insertion with the magnetic female connector body 300. Since the first upper cylinder 211 and the first lower cylinder 212 are coaxially arranged in the vertical direction, the smoothness and stability of the insertion process are ensured, avoiding problems such as misalignment and loose connections. This structure, while ensuring electrical reliability, also simplifies the assembly process and reduces production costs.

[0043] It should be noted that if the first lower cylinder 212 is set as a cylindrical structure, then the first through hole 310 is set as a cylindrical structure that matches it, so that the second metal protrusion 320 can be smoothly inserted into the first through hole 310.

[0044] In one embodiment, such as Figure 2 and Figure 3 As shown, the length between the two ends of the magnetic female seat body 300 in the horizontal direction is the first length, and the length between the two ends of the magnetic male seat body 200 in the horizontal direction is the second length. The ratio of the first length to the second length is 1:1.

[0045] In this embodiment, the length between the two opposite ends of the magnetic female base body 300 in the horizontal direction is the first length, so as to... Figure 3 Taking the shown perspective as an example, the first length can be the length and / or width of the magnetic female base body 300. Figure 3 L1, as shown, represents the first length of the magnetic female connector body 300 (this first length represents the length). Similarly, the length between the two ends of the magnetic male connector body 200 in the horizontal direction is the second length. Figure 2 Taking the perspective shown as an example, the second length can be the length and / or width of the magnetic male base body 200. Figure 2 The L2 shown represents the second length of the magnetic male connector body 200 (this second length represents the length). The ratio of the first length to the second length is 1:1, that is, the magnetic female connector body 300 and the magnetic male connector body 200 are of equal length and / or equal width. The magnetic female connector body 300 and the magnetic male connector body 200 are respectively located at... Figure 3 and Figure 2 The dimensions are kept consistent in the horizontal direction from the perspective shown. This allows for full contact between surfaces or edges during magnetic attraction, thereby improving the stability of magnetic attraction and preventing shaking or displacement. On the other hand, the size matching makes it easier for the first metal protrusion 210 and the first through hole 310 to achieve coaxial docking in the vertical direction, reducing the risk of displacement during insertion, improving the docking reliability of conductive contacts and the convenience of circuit connection of the light strip 100.

[0046] In one embodiment, such as Figure 1 , Figure 4 and Figure 5As shown, it also includes a fixing base 400, a light strip fixing assembly 500, and a fixing sheet metal 600; the magnetic male base body 200 is connected to the groove 410 opened in the first end face of the fixing base 400, the light strip 100 is connected to the first end face of the fixing base 400 through the light strip fixing assembly 500, the top of the fixing sheet metal 600 is connected to the second end face of the fixing base 400 through the magnetic female base body 300, and the first end face of the fixing base 400 and the second end face of the fixing base 400 are opposite to each other.

[0047] In this embodiment, taking the fixing base 400 as the reference component, the light strip 100 is connected to the first end face of the fixing base 400 through the light strip fixing assembly 500, and the fixing sheet metal 600 is magnetically connected to the second end face of the fixing base 400 through magnetic components (magnetic male body 200 and magnetic female body 300) (specifically, the magnetic female body 300 disposed on the top of the fixing sheet metal 600 is magnetically connected to the magnetic male body 200 disposed inside the fixing base 400). The two opposite end faces of the fixing base 400 are the first end face and the second end face, respectively. The first end face is the end face facing the light strip 100, and the second end face is the end face away from the light strip 100. It can also be understood that the second end face is the end face facing the fixing sheet metal 600.

[0048] A through hole is provided on one side wall of the mounting base 400, making the side wall U-shaped. This through hole provides a connection path for the first wire that is electrically connected to the first metal protrusion 210 on the magnetic male base body 200. That is, when the light strip fixing assembly 500 is connected to the first end face of the mounting base 400, the first wire can pass through the through hole and connect smoothly to the first metal protrusion 210.

[0049] The mounting base 400 has a groove 410 for placing the magnetic male connector body 200. The shape and size of the groove 410 are adapted to the magnetic male connector body 200. The opening of the groove 410 facing the first end face is called the first end face opening, and the opening of the groove 410 facing the second end face is called the second end face opening. The diameter of the first end face opening is larger than the diameter of the second end face opening, so that the light strip fixing assembly 500 can press the magnetic male connector body 200 into the groove 410 from above and abut against the bottom of the groove 410 while fixing the light strip 100, thereby achieving positioning and limiting. In this way, on the one hand, the magnetic male connector body 200 is prevented from popping out of the second end face opening under pressure. On the other hand, the unclosed groove 410 allows the first lower cylinder 212 on the magnetic male connector body 200 to be smoothly inserted into the first through hole 310 on the magnetic female connector body 300 during magnetic attraction.

[0050] The mounting base 400, serving as a container for the magnetic male base body 200, can be made of different materials depending on the application scenario of the light strip 100. For example, for applications where load-bearing strength requirements are not high but electrical safety and cost control are necessary, lightweight engineering plastics with good insulation properties and easy processing can be used. Examples of engineering plastics include polycarbonate (PC), acrylonitrile-butadiene-styrene copolymer (ABS), and polybutylene terephthalate (PBT). Furthermore, for lighting equipment requiring safety certifications (such as UL94 V0 level), flame-retardant engineering plastics with good flame-retardant and electrical insulation properties can be used. Examples of flame-retardant engineering plastics include flame-retardant polycarbonate (flame-retardant PC).

[0051] The top of the fixed sheet metal 600 (or the end face of the fixed sheet metal 600 facing the fixed base 400) has a groove 410 for fixing the magnetic female base body 300. After the magnetic female base body 300 is inserted into the groove 410, it can obtain support and limitation from the wall of the groove 410, and the magnetic male base body 200 is pressed into and abuts against the groove 410 on the fixed base 400 by the light strip fixing assembly 500. After assembly in this way, the operator only needs to align the second end face of the fixed base 400 with the top of the fixed sheet metal 600, and the magnetic male base body 200 and the magnetic female base body 300 can be automatically aligned and reliably attracted by the magnetic attraction between them, avoiding the tedious operation of repeated manual alignment; during disassembly, the operator only needs to hold the fixed sheet metal 600 and the fixed base 400 respectively, and use external force to overcome the magnetic attraction to achieve quick separation, which significantly improves the convenience of assembly and disassembly, and reduces the dependence on the precision of manual operation.

[0052] Specifically, when the magnetic female connector body 300 is fixed on the fixed sheet metal 600, and the magnetic male connector body 200 is disposed inside the groove 410 of the fixed base 400, the magnetic female connector body 300 and the magnetic male connector body 200 can be made of conductive metal alloy material (e.g., iron, cobalt, nickel, and other strongly magnetic alloy materials). This eliminates the need for separate conductive components, allowing electrical connection to be achieved through the magnetic female connector body 300 and the magnetic male connector body 200 themselves acting as a conductive circuit. More specifically, when the magnetic female connector body 300 is a conductive metal structure, the inner wall of the first through hole 310 is the inner wall of this metal body (magnetic female connector body 300), and the second metal protrusion 320 is electrically connected to the inner wall of the first through hole 310 through the magnetic female connector body 300. When the magnetic male connector body 200 and the magnetic female connector body 300 are magnetically attracted, the first lower cylinder 212 in the first metal protrusion 210 on the magnetic male connector body 200 is inserted into the first through hole 310 to achieve electrical contact, and at this time, the circuit is connected.

[0053] It can be understood that the magnetic male connector body 200 and magnetic female connector body 300 in this embodiment are different from the magnetic male connector body 200 and magnetic female connector body 300 in the previous example only in terms of their own materials. As for the first metal protrusion 210 on the magnetic male connector body 200 and the second metal protrusion 320 on the magnetic female connector body 300, they can refer to the previous example and adopt the same setting method as in the previous example, as long as it is ensured that the circuit can be connected when magnetically attracted.

[0054] In one embodiment, such as Figure 1 and Figure 4 As shown, the light strip fixing assembly 500 includes a pressure plate sheet metal 510, a connecting assembly 520, and a light strip fixing bracket 530 disposed on the side wall of the light strip 100; the light strip fixing bracket 530 is connected to the top of the pressure plate sheet metal 510; the pressure plate sheet metal 510 is connected to the first end face of the fixing base 400 through the connecting assembly 520.

[0055] In this embodiment, the LED strip mounting bracket 530 can be a strip-shaped structure, injection molded from plastic (such as PC, ABS, or flame-retardant PC material). The LED strip mounting bracket 530 is fixed to the side wall of the LED strip 100 by clips or screws to provide a stable mounting point. The LED strip mounting bracket 530 is connected to the side wall of the pressure plate sheet metal 510, and the connection method can be specifically configured according to actual needs. For example, it can be fixed by screws. A threaded hole or through hole is pre-set in the side wall of the pressure plate sheet metal 510, and a corresponding mounting hole is provided in the side wall of the LED strip mounting bracket 530. A metal screw is passed through the mounting hole of the bracket and screwed into the threaded hole of the pressure plate sheet metal 510, so that the bracket and the pressure plate sheet metal 510 are firmly connected. Alternatively, it can be connected by adhesive or hot melt bonding. Structural adhesive or hot melt adhesive is applied to the side wall of the pressure plate sheet metal 510, and the side wall of the LED strip mounting bracket 530 is pressed onto the adhesive layer. After curing, it is fixed.

[0056] The horizontal portion 513 of the pressure plate sheet metal 510 has a slot or mounting hole for connection with the top of the fixing base 400. The connecting assembly 520 can be a screw, nut, rivet, or clip for fixing the pressure plate sheet metal 510 to the first end face of the fixing base 400. The first end face of the fixing base 400 has a corresponding screw hole or insertion slot. The connecting assembly 520 achieves a reliable connection between the pressure plate sheet metal 510 and the fixing base 400 through the above structure.

[0057] In one embodiment, such as Figure 4 As shown, the pressure plate sheet metal 510 includes a first vertical portion 511 and a second vertical portion 512 located inside the groove 410, and a horizontal portion 513 parallel to the first end face of the fixing base 400; the first vertical portion 511 and the second vertical portion 512 are spaced apart and perpendicular to the end face of the horizontal portion 513 facing the fixing base 400; a first connecting hole 5131 and a second connecting hole 5132 are provided on opposite sides of the end of the horizontal portion 513. A third connecting hole 420 and a fourth connecting hole 430 are provided on opposite sides of the first end face of the fixing base 400; the third connecting hole 420 is directly opposite the first connecting hole 5131, and the fourth connecting hole 430 is directly opposite the second connecting hole 5132.

[0058] In this embodiment, the horizontal portion 513 is parallel to the first end face of the fixing base 400, forming a mounting reference surface. The horizontal portion 513 has a first connecting hole 5131 and a second connecting hole 5132 near its two ends for engaging with connecting components 520 (such as screws, rivets, or clips). A first vertical portion 511 and a second vertical portion 512 are spaced apart and vertically disposed on the end face of the horizontal portion 513 facing away from the light strip 100. When the pressure plate sheet metal 510 is assembled with the fixing base 400, the first vertical portion 511 and the second vertical portion 512 pass through the first end face opening of the fixing base 400 from top to bottom into the groove 410 and abut against the magnetic male base body 200 inside the groove 410.

[0059] The first end face of the fixing base 400 is provided with a third connecting hole 420 and a fourth connecting hole 430, which correspond to the first connecting hole 5131 and the second connecting hole 5132, respectively. During assembly, the first connecting hole 5131 and the third connecting hole 420 are aligned, and the second connecting hole 5132 and the fourth connecting hole 430 are aligned. Then, a connecting component 520 (such as a screw) is passed through these connecting holes to fix the pressure plate sheet metal 510 to the first end face of the fixing base 400.

[0060] In one embodiment, such as Figure 1As shown, it also includes a first spring 540 and a second spring 550 disposed inside the groove 410 and abutting against the magnetic male seat body 200; the first spring 540 is sleeved on the first vertical part 511, and the second spring 550 is sleeved on the second vertical part 512.

[0061] In this embodiment, a first spring 540 is sleeved on the first vertical portion 511, and a second spring 550 is sleeved on the second vertical portion 512. The elastic parameters of the first spring 540 and the second spring 550 are the same or similar. Preferably, both the first spring 540 and the second spring 550 are compression springs, and their free length is greater than the height of the first vertical portion 511 and the second vertical portion 512, so that when the magnetic male base body 200 is installed into the groove 410, the spring can form an abutment with the magnetic male base body 200 under compression. Further, the length and width of the groove 410 are slightly larger than the length and width of the magnetic male base body 200 by 0.5 to 2 mm, so that after the magnetic male base body 200 is installed into the groove 410, it retains a preset movement space within the groove 410, so that the magnetic male base body 200 can generate a small displacement during adsorption and disassembly.

[0062] When the light strip 100 is assembled with the mounting base 400, the magnetic male connector body 200 is pressed into the groove 410 and abuts against the first spring 540 and the second spring 550, so that the springs provide a continuous elastic force to the magnetic male connector body 200 after being compressed. Thus, during assembly, the first spring 540 and the second spring 550 can provide a certain elastic buffering effect, which helps to avoid structural damage caused by rigid collisions. When the mounting base 400 is disassembled from the mounting sheet metal 600, the mounting base 400 is manually separated from the mounting sheet metal 600, and the elastic potential energy stored in the first spring 540 and the second spring 550 is released, causing the magnetic male connector body 200 to automatically spring back to its initial position, thereby preventing the magnetic male connector body 200 from wearing due to excessive friction. Through the above structure, the first spring 540 and the second spring 550 not only play a supporting and buffering role, but also improve the reliability and durability of the magnetic male connector body 200 during assembly and disassembly.

[0063] Specifically, during assembly, firstly, the first spring 540 is fitted onto the first vertical portion 511 of the pressure plate sheet metal 510, allowing the first spring 540 to slide axially along the first vertical portion 511. Then, the second spring 550 is fitted onto the pressure plate sheet metal 510, allowing the second spring 550 to slide axially along the second vertical portion 512. Next, the first vertical portion 511 and the second vertical portion 512, each fitted with a spring, are inserted into the groove 410 of the fixing base 400. During insertion, the first spring 540 and the second spring 550 are positioned within the internal space of the groove 410 and abut against the magnetic male base body 200, providing elastic support and cushioning. Then, the position of the horizontal portion 513 of the pressure plate sheet metal 510 is adjusted so that the first connecting hole 5131 and the second connecting hole 5132 are aligned with the threaded holes on the fixing base 400. Screws can then be used to fix the pressure plate sheet metal 510 to the first end face of the fixing base 400. At this time, the spring remains compressed and applies elastic force to the magnetic male connector body 200, thereby ensuring that the magnetic male connector body 200 has stable adsorption and rebound performance during connection. Align the mounting position of the light strip holder 530 with the horizontal portion 513 of the pressure plate sheet metal 510, and install the light strip holder 530 onto the horizontal portion 513 of the pressure plate sheet metal 510 using screws, rivets, or clips. Finally, insert the side wall of the light strip 100 into the slot or limiting structure of the light strip holder 530; the clamping action of the slot achieves stable positioning of the light strip 100. In one embodiment, such as Figure 1 As shown, the connecting component 520 includes a first connector 521 and a second connector 522; the first connector 521 is sequentially inserted through the first connecting hole 5131 and the third connecting hole 420, and the second connector 522 is sequentially inserted through the second connecting hole 5132 and the fourth connecting hole 430.

[0064] In this embodiment, the first connector 521 and the second connector 522 may be made of the same component or different components. For example, both the first connector 521 and the second connector 522 may use screws or locating pins of the same specification.

[0065] Specifically, the pressure plate sheet metal 510 and the fixing seat 400 are positioned relative to each other, aligning the first connecting hole 5131 with the third connecting hole 420, and the second connecting hole 5132 with the fourth connecting hole 430, respectively. This ensures the precise positional relationship between the pressure plate sheet metal 510 and the fixing seat 400, preventing assembly misalignment and guaranteeing the stability of the overall structure. Then, the first connecting piece 521 is sequentially inserted through the first connecting hole 5131 and the third connecting hole 420, initially assembling and fixing the pressure plate sheet metal 510 and the fixing seat 400 together. Simultaneously, the second connecting piece 522 is sequentially inserted through the second connecting hole 5132 and the fourth connecting hole 430, completely assembling and fixing the pressure plate sheet metal 510 and the fixing seat 400 together. This fixing method using connecting pieces allows for easy separation of the pressure plate sheet metal 510 and the fixing seat 400 simply by disassembling the connecting pieces when replacing the light strip 100 or performing maintenance, improving maintenance efficiency and reducing labor costs.

[0066] like Figure 1 As shown, this utility model embodiment provides a lighting device, which is applied to the magnetic LED strip docking mechanism in any of the foregoing embodiments, and further includes a lamp body 700 and a lamp cover 800 connected to the top of the lamp body 700; the magnetic LED strip docking mechanism is disposed in the inner cavity formed after the lamp cover 800 and the lamp body 700 are connected.

[0067] In this embodiment, the lamp body 700 is preferably made of aluminum alloy profile, and its top has a mounting groove extending along the length of the lamp body 700. A wiring channel is reserved inside the lamp body 700 to accommodate the power cord (not shown in the figure), ensuring the neatness and safety of the wiring. The second metal protrusion 320 on the magnetic female connector body 300 is electrically connected to the power cord, thereby achieving electrical connection with the power source. The lamp cover 800 can be made of PC or acrylic material with good light transmittance, and its bottom has a snap-fit ​​part that matches the mounting groove on the top of the lamp body 700. Both the lamp cover 800 and the lamp body 700 can be designed as an open hollow structure. When the lamp cover 800 and the lamp body 700 are detachably connected to form an integral structure via a snap-fit ​​method, the internal space of this integral structure is the cavity formed after the lamp cover 800 and the lamp body 700 are connected, and the magnetic LED strip docking mechanism is located in this cavity.

[0068] Specifically, a fixed sheet metal 600, equipped with a magnetic female connector body 300, is vertically positioned on the inner wall of the lamp body 700, while the LED strip 100 is housed inside the lamp cover 800. The LED strip 100 is connected to the first end face of a fixed base 400 containing a magnetic male connector body 200 via an LED strip fixing assembly 500, and the second end face of the fixed base 400 is aligned with the top of the fixed sheet metal 600. Thus, when the lamp cover 800 and the lamp body 700 are assembled, the magnetic male connector body 200 within the fixed base 400 and the magnetic female connector body 300 on the top of the fixed sheet metal 600 are precisely aligned and magnetically connected, thereby achieving automatic circuit connection. This method not only simplifies the electrical connection operation between the LED strip 100 and the lamp body 700 but also ensures the stability and reliability of the connection process through magnetic positioning, reducing potential contact problems caused by manual insertion and removal.

[0069] Furthermore, when the lamp cover 800 separates from the lamp body 700, the second end face of the fixing base 400 separates from the top of the fixing sheet metal 600, the magnetic male connector body 200 and the magnetic female connector body 300 disengage from the magnetic state, and the circuit is automatically disconnected. This structure achieves electrical separation while avoiding mechanical wear caused by frequent operation in traditional plug-in structures, thus improving overall service life and ease of maintenance. Therefore, this embodiment not only achieves magnetic connection and disconnection of the circuit but also improves assembly efficiency and safety of use.

[0070] In this embodiment, at least two magnetic strip connection mechanisms can be spaced apart along the extension direction of the strip 100, according to the actual length of the strip 100, in the lamp cover 800 and the lamp body 700. Through multi-point magnetic connection, on the one hand, the force on the strip 100 can be effectively distributed, preventing a single connection point from bearing the entire connection force and causing local loosening or failure, thus improving the structural stability; on the other hand, the electrical parallel design of multiple connection mechanisms ensures that the circuit remains connected even if poor contact occurs at individual connection points, thereby improving the reliability of the lighting device. Furthermore, the spaced arrangement allows for smoother and more stable installation and removal of the strip 100, preventing bending, twisting, or damage caused by excessive length, further extending the service life of the strip 100.

[0071] The working process of this utility model is as follows: In this embodiment, a first wire is pre-laid on the light strip 100, and the first wire is electrically connected to a first metal protrusion 210 on the magnetic male connector body 200 located at the bottom of the light strip 100. The magnetic female connector body 300 is located on the end face of the magnetic male connector body 200 facing away from the light strip 100. A first through hole 310 adapted to the first metal protrusion 210 is opened on the side facing the magnetic male connector body 200, and a second metal protrusion 320 electrically connected to the power supply is provided on the side facing away from the magnetic male connector body 200. The inner wall of the first through hole 310 is provided with a conductive layer electrically connected to the second metal protrusion 320. When the magnetic male connector body 200 and the magnetic female connector body 300 are magnetically attracted to each other, the first metal protrusion 210 inserts into the first through hole 310 and contacts the conductive layer. Power is then conducted through the second metal protrusion 320 on the magnetic female connector body 300, through the conductive layer on the first through hole 310, to the first metal protrusion 210 on the magnetic male connector body 200, and then input to the LED strip 100 via the first wire electrically connected to the first metal protrusion 210, illuminating the LED strip 100. Conversely, when the magnetic male connector and the magnetic female connector are separated, the first metal protrusion 210 loses contact with the first through hole 310, the circuit is broken, and the LED strip 100 immediately turns off. Thus, this embodiment of the invention achieves power supply to the LED strip 100 through the magnetic connection between the magnetic male connector body 200 and the magnetic female connector body 300. Its structure is simple, disassembly is convenient, and the ease of using the LED strip 100 is improved.

[0072] In summary, this utility model embodiment provides a magnetic LED strip docking mechanism, which includes an LED strip 100 with a first conductor on it; a magnetic male connector body 200 disposed at the bottom of the LED strip 100, with a first metal protrusion 210 electrically connected to the first conductor on the magnetic male connector body 200; and a magnetic female connector body 300 disposed on the end face of the magnetic male connector body 200 facing away from the LED strip 100 and magnetically attracted to the magnetic male connector body 200. The end face of the magnetic female connector body 300 facing the magnetic male connector body 200 has a first through hole 310, and the end face of the magnetic female connector body 300 facing away from the magnetic male connector body 200 has a second metal protrusion 320 electrically connected to a power source. The inner wall of the first through hole 310 is provided with a conductive layer electrically connected to the second metal protrusion 320, and the first metal protrusion 210 is inserted into the first through hole 310 and contacts the conductive layer. This embodiment of the utility model achieves power supply to the LED strip 100 through a magnetic connection between the magnetic male base body 200 and the magnetic female base body 300. Its structure is simple, and it is easy to disassemble, which improves the convenience of using the LED strip 100.

[0073] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
