DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0034] As shown in the figure, the embodiment discloses a lighting system for handheld and head-mounted use, comprising a mounting base 1, a rotating base 2, an adjusting rod 3 and a lighting device 4. Figures 1 to 10 The mounting base 1 is a plastic or light metal piece, such as an aluminum piece, and is provided with mounting holes 5, which are mounted on the side injection molding piece of the helmet 29 by fasteners. Specifically, the front mounting hole 5 of the mounting base 1 is fixed on the side injection molding piece of the helmet 29 by a bolt 7 and a nut 8, and the rear mounting hole 5 is fixed on the side injection molding piece of the helmet 29 by a stud 9 and a nut 8.

[0035] The rotating base 2 is a plastic or light metal piece, such as an aluminum piece, and has a through hole 10, which is connected with the bolt 7 through the through hole 10 to realize the rotating installation of the rotating base 2 on the mounting base 1.

[0036] The adjusting rod 3 is a plastic or metal piece, which is rotatably installed at the rear of the mounting base 1 and rotates around its axis to adjust the rotating angle of the rotating base 2. That is, the rotating axis of the adjusting rod 3 is not coplanar with and perpendicular to the rotating axis of the rotating base 2. As one adjusting mode, the rear of the rotating base 2 is provided with a plurality of tooth portions 11 distributed along a circular arc line, and the center of the circular arc line is located on the rotating axis of the rotating base 2. The adjusting rod 3 is provided with a worm portion 12, which is meshed and connected with the tooth portions 11. Obviously, the mounting mode of the adjusting rod 3 on the mounting base 1 is a prior art, and there must be a space on the mounting base 1 to install and accommodate the worm portion 12, which also belongs to the prior art, so it is not described in detail. When the adjusting rod 3 is rotated, the meshing of the tooth portions 11 can drive the rotating base 2 to rotate around the axis of the through hole 10. The number of tooth portions 11 is determined according to the rotating angle of the rotating base 2, and as a preferred example, the rotating angle of the rotating base 2 is ±5°, and the number of tooth portions 11 is 13.

[0037] As a preferred example, the rear of the mounting base 1 is provided with a limiting groove 13 with a limiting block 14, and the limiting block 14 is located outside the limiting groove 13, which is used to limit the tooth portions 11 at the rear of the rotating base 2 to prevent lateral deviation.

[0038] As a preferred example, in order to limit the rotating angle of the rotating base 2, the upper surface of the rotating base 2 has a first limiting portion 15 to limit the forward rotation, and the lower surface is provided with a second limiting portion 16 to limit the reverse rotation. The first limiting portion 15 and the second limiting portion 16 can realize the limiting of the rotating base 2 after being in contact with the mounting base 1, respectively.

[0039] As a preferred example, in order to limit the rotating angle of the rotating base 2, the upper surface of the rotating base 2 has a first limiting portion 15 to limit the forward rotation, and the lower surface is provided with a second limiting portion 16 to limit the reverse rotation. The first limiting portion 15 and the second limiting portion 16 can realize the limiting of the rotating base 2 after being in contact with the mounting base 1, respectively.

[0040] The lighting device 4 is magnetically attached to the rotating base 2. As a preferred example, the rotating base 2 is provided with a guide groove structure 17, and the lighting device 4 is provided with a magnetic body 18 matching the guide groove structure 17. The guide groove structure 17 is a metal structure capable of being magnetically attached, and has two vertically symmetrical guide slopes 19. Obviously, the magnetic body 18 also has a magnetic surface 20 matching each guide slope 19. That is, when the lighting device 4 approaches the rotating base 2, the magnetic body 18 and the guide groove structure 17 are magnetically attached, and are positioned by the guide slope 19 and the magnetic surface 20. After positioning, the lighting device 4 can still be moved back and forth along the guide slope 19. Compared with the existing rotating clamping installation mode, this assembly mode has low positioning difficulty, and can be positioned and assembled without visual positioning, and is more convenient and fast to operate.

[0041] As a preferred example, in order to improve the stability of the lighting device 4 and prevent it from falling off when subjected to a large vibration, the lighting device 4 can also be fixedly installed to be completely locked. Specifically, the lighting system further comprises a locking rod 21 which is a plastic or metal part. The locking rod 21 is movably installed on the rotating base 2 and is limited by the limiting bosses 6 at the upper and lower ends. After the lighting device 4 is inserted with the rotating base 2, the axial movement of the locking rod 21 can lock the lighting device 4 and the rotating base 2 to form locking and unlocking.

[0042] More specifically, the lighting device 4 is provided with opposite first and second plugs 23 and 24, and the rotating base 2 has a first plug opening 28 matching the first plug 23. The locking rod 21 has a clamping part 25 matching the second plug 24. After the first plug 23 is inserted with the first plug opening 28, the forward movement of the locking rod 21 can cause the clamping part 25 to be clamped with the second plug 24 to form locking, and the reverse movement of the locking rod 21 can cause the clamping part 25 to be separated from the second plug 24 to release the locking. That is, when the lighting device 4 is assembled, it is first positioned by magnetic attachment, then the first plug 23 at the rear of the lighting device 4 is inserted into the first plug opening 28 by moving the lighting device 4 backward, then the locking rod 21 is pressed down to clamp the second plug 24 with the clamping part 25, so that the lighting device 4 is fixed on the guide groove structure 17. When disassembling, the locking rod 21 is pushed up to separate the clamping part 25 from the second plug 24, and then the lighting device 4 is removed.

[0043] As a preferred example, the lighting system further comprises a reset spring 22 installed on the locking rod 21 and driving the locking rod 21 to have a tendency to keep its locking position. That is, before the lighting device 4 is installed, the locking rod 21 needs to be pressed down first, and then released after positioning and pre-fixing, so that it returns to the locking position under the action of the elastic force.

[0044] As a preferred example, the magnetic body 18 is installed on both sides of the lighting device 4, and the first plug 23 and the second plug 24 are arranged at the end of each magnetic body 18. The first plug 23, the second plug 24 and the magnetic body 18 are integrally connected, that is, the first plug 23 and the second plug 24 also have magnetic force.

[0045] As a preferred example, the lighting device 4 is provided with a hand-held strap 26. The operation of the hand-held strap 26 is that when the operator holds and operates, it can be worn on the outside of the fingers, instead of being held in the traditional way of gripping, which has the advantage of freeing the fingers so that other equipment or tools can be gripped. The hand-held strap 26 can be a strap with buckles or a stretchy strap with elasticity according to the needs.

[0046] As a preferred example, when the lighting device 4 is held in a wearing manner, a conical protrusion 27 can also be arranged on the upper side of the lighting device 4, so as to have a breaking function in special situations.

[0047] As shown in Figures 8 to 10 The lighting system in the present application can be installed on one side of the helmet 29 in a single-sided installation manner, or can be installed on both sides of the helmet 29 in a double-sided installation manner. When installed on both sides, the illumination angle of each lighting device 4 can be changed to expand the illumination range.
