[0025] The following description, with reference to the accompanying drawings, describes a magnetic tail-type multi-functional flashlight according to an embodiment of the present invention.
[0026] See Figures 1 to 6 A magnetic tail-type multi-functional flashlight according to an embodiment of the present invention includes a lamp head assembly 1, a tube body 2, and a battery 3. The lamp head assembly 1 includes a housing 4, a front lamp assembly, a side lamp assembly, a protective ring 5, a connector 6, a switch 7, and a control circuit 8. Operating the switch 7 can transmit a control signal to the control circuit 8, thereby controlling the operation of the front lamp assembly and the side lamp assembly.
[0027] The outer periphery of the cross-section at both ends of the housing 4 is an arc-shaped triangle, and the connecting member 6 is fixed to the rear end of the housing 4. The outer periphery of the cross-section at the front end of the cylindrical body 2 is also an arc-shaped triangle, and the front end of the cylindrical body 2 is fitted onto the connecting member 6 and abuts against the rear end of the housing 4. In this embodiment, the outer periphery of the cross-section of the cylindrical body 2 gradually changes from an arc-shaped triangle at the front end to a circle at the rear end. Both the outer shell and the cylindrical body 2 adopt an irregular shape design, which can improve grip stability and prevent rolling.
[0028] A magnet 9 is provided at the tail of the cylinder 2. The battery 3 is installed in the space surrounded by the cylinder 2 and the shell 4. In scenarios such as mechanical repair, industrial maintenance, and automobile maintenance, the magnet 9 can be used to attach the magnetic tail-type multi-functional flashlight to the iron parts of mechanical equipment.
[0029] The headlight assembly includes an LED chip 10, a Fresnel lens 11, and a lens 22 fixing assembly. The Fresnel lens 11 includes a circumferential wall 12 that gradually tapers towards the direction of the LED chip 10, as shown in the figure. Figure 3From a viewing angle, the circumferential wall 12 gradually tapers from top to bottom, with a wide diameter at the front end and a narrow diameter at the rear end. The lens 22 fixing assembly includes an outer fixing cylinder 13, a first sealing ring 14, a tail top ring 15, and a lamp holder 16. The circumferential edge at the front end of the outer fixing cylinder 13 extends inward to form an inner retaining ring portion 17 and extends outward to form an outer retaining ring portion 18. The Fresnel lens 11 is arranged inside the outer fixing cylinder 13, and the circumferential edge at the wide diameter front end of its circumferential wall 12 abuts against the inner retaining ring portion 17. The first sealing ring 14 is sleeved on the circumferential wall 12 of the Fresnel lens 11 and is pressed against by the tail top ring 15, so that it simultaneously abuts against the circumferential wall 12 of the Fresnel lens 11 and the inner circumferential wall of the outer fixing cylinder 13. Specifically, the outer peripheral wall of the tail top ring 15 is formed with an external thread, and the inner peripheral wall of the outer fixing cylinder 13 is formed with an internal thread that mates with the external thread. During assembly, rotating the tail top ring 15 can move the tail top ring 15 toward the inner retaining ring 17 until the tail top ring 15 abuts against the first sealing ring 14 and simultaneously presses against the circumferential wall 12 of the Fresnel lens 11 and the inner peripheral wall of the outer fixing cylinder 13.
[0030] The LED beads 10 are arranged inside the lamp holder 16. The lamp holder 16 forms an installation space to accommodate the outer fixing cylinder 13. The outer peripheral wall of the outer fixing cylinder 13 has an external thread, and the inner peripheral wall of the installation space of the lamp holder 16 has an internal thread that mates with the external thread. During assembly, the outer fixing cylinder 13 can be installed in the installation space of the lamp holder 16 by rotating it.
[0031] The protective ring 5 has an arc-shaped triangular cross-section. An annular ring 19 extends inward from the center of the inner wall of the protective ring 5, and the outer retaining ring 18 abuts against the annular ring 19, causing the circumferential edge of the rear end of the protective ring 5 to abut against the circumferential edge of the front end of the housing 4. The outer fixing cylinder 13 is fitted with a second sealing ring 20, which is pressed against the circumferential edge of the lamp holder 16 near the outer retaining ring 18, thus simultaneously abutting against the inner side of the annular ring 19 and the outer retaining ring 18.
[0032] The lamp holder 16 is fixedly installed inside the housing 4. Specifically, the lamp holder 16 is fixedly installed inside the housing 4 by bolts.
[0033] The side light assembly includes an LED light source 21 installed inside the housing 4 and a lens 22 fixed to an opening on the periphery of the housing 4. The LED light source 21 can be an SMD LED (surface mount LED). In this embodiment, the housing 4 has a clamping portion 23 formed on the side facing away from the lens 22, and the clamping portion 23 extends towards the barrel 2. Adding the clamping portion 23 allows the magnetic tail multi-functional flashlight to be clipped to a pocket or collar of clothing, making it more flexible, especially in applications where the side light assembly provides light. (See reference...) Figure 5From the perspective, the switch 7 is positioned below the lens 22.
[0034] The connector 6 is fitted with a third sealing ring 24 and a fourth sealing ring 25. The third sealing ring 24 abuts against the inner wall of the rear end of the housing 4, and the fourth sealing ring 25 abuts against the inner wall of the front end of the cylindrical body 2. In this embodiment, the connector 6 is generally cylindrical, and the battery 3 extends into the connector 6.
[0035] When the magnetic tail-type multi-functional flashlight of this embodiment is applied to scenarios such as mechanical repair, industrial maintenance, and automobile maintenance, the magnet at its tail can be used to attach the magnetic tail-type multi-functional flashlight to the iron material surface of the mechanical equipment, freeing up the hands and enabling precise lighting.
