Technical Field

[0001] This utility model relates to the field of lens module technology, and specifically discloses a magnetically replaceable lens module. Background Technology

[0002] A lens module is a component that integrates an optical lens and a light source adapter structure. It is widely used in the field of automotive lighting. Its core function is to focus, diffuse, or shape the light emitted by the light source through the lens to form a specific light pattern, thereby precisely controlling the illumination range, intensity, and uniformity to ensure that the lighting effect meets the needs of the application scenario.

[0003] In existing technologies, lens modules are typically fixed to housings using screws or other fasteners. The module is secured inside the housing with screws, and the lampshade is then fastened to the front of the housing with fasteners for protection. However, this method has significant drawbacks: when replacing the lens module, the lampshade must be removed first, and then the fasteners securing the module must be unscrewed one by one to remove the module. The entire process is cumbersome, time-consuming, and inefficient, severely impacting ease of use.

[0004] Therefore, a magnetically replaceable lens module is needed to solve the above problems. Utility Model Content

[0005] This invention proposes a magnetically replaceable lens module, which facilitates the disassembly and replacement of a disc integrating multiple lenses. It is simple to operate, quick to use, and highly efficient, effectively improving ease of use.

[0006] This utility model is implemented as follows: a magnetic replaceable lens module includes a housing, a circuit board installed inside the housing, multiple LED chips arranged on the left side of the circuit board, two wires arranged on the right side of the circuit board, a disc inserted inside the housing, and multiple cylinders fixedly connected through the outer wall of the disc, with lenses arranged inside each of the multiple cylinders. A magnetic attraction mechanism is provided on the outer side of the disk. The magnetic attraction mechanism includes multiple positioning grooves opened on the inner wall of the housing. Positioning blocks that are fixedly connected to the disk are inserted into the interior of each of the multiple positioning grooves. Permanent magnets are fixedly connected to the right end of the inner wall of each of the multiple positioning grooves. A magnetic conductive substrate that is in contact with the permanent magnet is fixedly connected to the right end of each of the multiple positioning blocks. A limiting mechanism is provided on the outer side of the disk. The limiting mechanism includes a threaded cover that is threaded to the outer wall of the housing. The left ends of the plurality of positioning blocks are fixedly connected to limiting rods, and the plurality of limiting rods are in contact with the left end of the inner wall of the threaded cover.

[0007] As a preferred embodiment of the magnetic replaceable lens module of this utility model, the right end of the housing has two through holes, and the two wires pass through the interior of the two through holes respectively. The inner walls of the two through holes are provided with sealing rings that abut against the two wires respectively through grooves.

[0008] As a preferred embodiment of the magnetic replaceable lens module of this utility model, a fixing ring is fixedly connected to the outer wall of the housing, and a sealing gasket is embedded in the left side of the fixing ring through a groove, which abuts against the right end of the threaded cover.

[0009] As a preferred embodiment of the magnetic replaceable lens module of this utility model, the left end of the threaded cover is provided with a mounting groove, and a light-transmitting plate is fixedly connected inside the mounting groove.

[0010] In a preferred embodiment of the magnetic replaceable lens module of this utility model, the plurality of lenses correspond to the positions of the plurality of LED chips, and the plurality of LED chips are located inside the plurality of cylinders.

[0011] In a preferred embodiment of the magnetic replaceable lens module of this utility model, the plurality of limiting rods extend to the outside of the housing.

[0012] The beneficial effects of this utility model are: When installing a disc integrating multiple lenses, the disc is first positioned and fixed within the housing by the attraction between the permanent magnet and the magnetic substrate, ensuring precise alignment of the lenses and LED chips. Then, the disc is secured by tightening the threaded cover to prevent the magnetic components from detaching. Disassembly simply requires loosening the threaded cover to overcome the magnetic force and pull the disc out.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0017] Please see Figures 1-5 A magnetic replaceable lens module includes a housing 1, a circuit board 2 installed inside the housing 1, multiple LED chips 3 arranged on the left side of the circuit board 2, two wires 4 arranged on the right side of the circuit board 2, a disc 7 inserted inside the housing 1, multiple cylinders 8 fixedly connected through the outer wall of the disc 7, and lenses 9 arranged inside the multiple cylinders 8. A magnetic attraction mechanism is provided on the outer side of the disk 7. The magnetic attraction mechanism includes multiple positioning grooves 10 opened on the inner wall of the housing 1. Positioning blocks 11 that are fixedly connected to the disk 7 are inserted into the interior of each of the multiple positioning grooves 10. Permanent magnets 12 are fixedly connected to the right end of the inner wall of each of the multiple positioning grooves 10. A magnetic conductive substrate 13 that is in contact with the permanent magnet 12 is fixedly connected to the right end of each of the multiple positioning blocks 11. A limiting mechanism is provided on the outer side of the disc 7. The limiting mechanism includes a threaded cover 15 that is threaded to the outer wall of the housing 1. The left ends of multiple positioning blocks 11 are fixedly connected to limiting rods 14, and the multiple limiting rods 14 are in contact with the left end of the inner wall of the threaded cover 15.

[0018] In this embodiment: when installing the disk 7 with multiple lenses 9, firstly, multiple positioning blocks 11 on the outer wall of the disk 7 are inserted into multiple positioning grooves 10 on the inner wall of the housing 1, and the magnetic substrate 13 on the right end of the positioning block 11 is attached to the permanent magnet 12 on the right end of the inner wall of the positioning groove 10. By using the attraction force between the permanent magnet 12 and the magnetic substrate 13, the disk 7 is initially positioned and fixed inside the housing 1, ensuring that the multiple lenses 9 are accurately aligned with the multiple LED chips 3 respectively.

[0019] After the initial fixing is completed, the threaded cover 15 is threaded onto the outer wall of the housing 1. When the threaded cover 15 is tightened, the left end of the inner wall of the threaded cover 15 will fit against the left end of the multiple limiting rods 14, thereby limiting the disk 7 and preventing the permanent magnet 12 from separating from the magnetic substrate 13.

[0020] When it is necessary to replace the disc 7 with lenses 9, simply loosen the threaded cover 15 in the reverse direction to separate it from the limiting rod 14, thereby releasing the restriction on the positioning block 11. Then, the attraction force between the permanent magnet 12 and the magnetic substrate 13 can be overcome, and the disc 7 and positioning block 11 can be pulled out of the positioning groove 10 through the limiting rod 14, completing the disassembly. The entire process does not require the removal of multiple fasteners, making it easy to disassemble and replace the disc 7 with multiple lenses 9. The operation is simple, time-saving, and efficient, effectively improving the ease of use.

[0021] During normal use, after the circuit board 2 is connected to the power supply through the two wires 4 on the right side, the current is transmitted to the circuit board 2 through the wires 4, driving the multiple LED chips 3 on the left side of the circuit board 2 to emit light. Since the multiple LED chips 3 are located inside the multiple cylinders 8 respectively, and correspond one-to-one with the position of the lens 9 inside the cylinder 8, the light emitted by the LED chip 3 will first enter the corresponding cylinder 8, and after being focused, refracted or shaped by the lens 9, it will pass through the light-transmitting plate 19 in the mounting groove 18 at the left end of the threaded cover 15 and be emitted outward, forming a light pattern that meets the usage requirements.

[0022] As a technical optimization of this utility model, two through holes 5 are provided at the right end of the housing 1. Two wires 4 pass through the interior of the two through holes 5 respectively. The inner walls of the two through holes 5 are provided with sealing rings 6 that abut against the two wires 4 respectively through grooves.

[0023] In this embodiment: the two wire holes 5 on the right end of the housing 1 allow the two wires 4 of the circuit board 2 to pass through. The sealing ring 6 in the groove of the inner wall of the wire hole 5 abuts against the wire 4, which can seal the gap between the wire 4 and the wire hole 5, and prevent dust and moisture from entering the interior of the housing 1 through the wire hole 5.

[0024] As a technical optimization of this utility model, a fixing ring 16 is fixedly connected to the outer wall of the housing 1, and a sealing gasket 17 is embedded in the left side of the fixing ring 16 through a groove, which abuts against the right end of the threaded cover 15.

[0025] In this embodiment: the sealing gasket 17 in the groove of the fixing ring 16 abuts against the right end of the threaded cover 15. When the threaded cover 15 is tightened, the sealing gasket 17 is squeezed and deformed, further preventing external impurities from entering.

[0026] As a technical optimization of this utility model, the left end of the threaded cover 15 is provided with a mounting groove 18, and a light-transmitting plate 19 is fixedly connected inside the mounting groove 18.

[0027] In this embodiment, the light-transmitting plate 19 can both allow the light emitted from the lens 9 to pass through to achieve the illumination function and cover the opening of the threaded cover 15, providing physical protection for the disk 7, lens 9 and other components inside the housing 1.

[0028] As a technical optimization of this utility model, multiple lenses 9 correspond to the positions of multiple LED chips 3, and the multiple LED chips 3 are located inside multiple cylinders 8.

[0029] In this embodiment, multiple lenses 9 correspond one-to-one with multiple LED chips 3, and the LED chips 3 are located inside the cylinder 8, so that the light emitted by the LED chips 3 can accurately enter the corresponding cylinder 8.

[0030] As a technical optimization of this utility model, multiple limiting rods 14 extend to the outside of the housing 1.

[0031] In this embodiment, multiple limiting rods 14 extend to the outside of the housing 1, and the limiting rods 14 can be pulled from the outside of the housing 1 to facilitate the removal of the disc 7 and the positioning block 11 from the positioning groove 10.

[0032] The working principle and usage process of this utility model are as follows: When installing the disc 7 with multiple lenses 9, firstly, multiple positioning blocks 11 on the outer wall of the disc 7 are inserted into multiple positioning grooves 10 on the inner wall of the housing 1, and the magnetic substrate 13 on the right end of the positioning block 11 is attached to the permanent magnet 12 on the right end of the inner wall of the positioning groove 10. By using the attraction force between the permanent magnet 12 and the magnetic substrate 13, the disc 7 is initially positioned and fixed inside the housing 1, ensuring that the multiple lenses 9 are accurately aligned with the multiple LED chips 3.

[0033] After initial fixing, the threaded cover 15 is threaded onto the outer wall of the housing 1. When the threaded cover 15 is tightened, the left end of the inner wall of the threaded cover 15 will abut against the left ends of the multiple limiting rods 14, thereby limiting the disk 7 and preventing the permanent magnet 12 from detaching from the magnetic substrate 13. At this time, the sealing gasket 17 on the left side of the fixing ring 16 will abut against the right end of the threaded cover 15, and since the sealing rings 6 inside the two wire holes 5 abut against the two wires 4 respectively, dust and moisture are prevented from entering the housing 1 and affecting the operation of the components.

[0034] When it is necessary to replace the disc 7 with lenses 9, simply loosen the threaded cover 15 in the reverse direction to separate it from the limiting rod 14, thereby releasing the restriction on the positioning block 11. Then, the attraction force between the permanent magnet 12 and the magnetic substrate 13 can be overcome, and the disc 7 and positioning block 11 can be pulled out of the positioning groove 10 through the limiting rod 14, completing the disassembly. The entire process does not require the removal of multiple fasteners, making it easy to disassemble and replace the disc 7 with multiple lenses 9. The operation is simple, time-saving, and efficient, effectively improving the ease of use.

[0035] During normal use, after the circuit board 2 is connected to the power supply through the two wires 4 on the right side, the current is transmitted to the circuit board 2 through the wires 4, driving the multiple LED chips 3 on the left side of the circuit board 2 to emit light. Since the multiple LED chips 3 are located inside the multiple cylinders 8 respectively, and correspond one-to-one with the position of the lens 9 inside the cylinder 8, the light emitted by the LED chip 3 will first enter the corresponding cylinder 8, and after being focused, refracted or shaped by the lens 9, it will pass through the light-transmitting plate 19 in the mounting groove 18 at the left end of the threaded cover 15 and be emitted outward, forming a light pattern that meets the usage requirements.
