According to the LED assembly angle adjusting structure and the portable power source lighting device, the mounting seat and the LED module are hinged through the rotating shaft and the rotating shaft groove, when the lighting angle needs to be adjusted, the rotating angle of the LED module relative to the mounting seat can be adjusted through the relative rotation between the rotating shaft and the rotating shaft groove, and when the proper angle gear is adjusted, the rotating shaft clamping groove can be clamped through the elastic buckle on the rotating shaft groove, so that the LED module is hovered and fixed. The problem that the illumination angle of the LED module is not adjustable is solved.

Example 1

The embodiment provides an angle adjusting structure 100 of an LED assembly, the LED assembly comprises a mounting seat 20 arranged on a power supply shell 30 and an LED module 10 hinged with the mounting seat 20, the adjusting structure comprises a rotating shaft groove 21 and a rotating shaft 11 arranged in the rotating shaft groove 21;

the rotating shaft groove 21 is arranged on the mounting seat 20, and the rotating shaft 11 is arranged on the LED module 10;

an elastic buckle 211 is arranged in the rotating shaft groove 21;

a plurality of clamping grooves 111 are annularly distributed on the rotating shaft 11 along the axis;

the elastic buckle 211 is rotatably clamped with any clamping groove 111.

In the prior art, the LED assembly may generally consist of a power supply housing 30, an LED module 10, and a mount 20. The LED module 10 may be a square circuit board with a circuit structure such as an LED lamp and the like inside, for providing an illumination light source, while the mounting base 20 may be a square cover plate with a groove adapted to the shape of the LED module 10, for placing the LED module 10, and the power supply housing 30 is a cover plate with a substantially L-shape, and is connected with the mounting base 20, so as to fix the LED assemblies. Meanwhile, a through hole matched with the LED module 10 is formed in one surface close to the LED module 10 so as to avoid shielding the illumination light source provided by the LED module 10. However, the above connection structure has no means to adjust the rotation angle of the LED module 10 with respect to the mounting base 20, resulting in limited illumination area and failure to meet the illumination requirements of the multi-angle illumination working environment.

Referring to fig. 1 to 5, in the present embodiment, an adjusting structure is installed in the LED assembly, and can be used to adjust the rotation angle of the LED module 10 relative to the mounting base 20, hover at a desired angle, and connect the LED module 10 with the mounting base 20. Specifically, the adjusting structure may be composed of a rotating shaft groove 21 and a rotating shaft 11. The rotating shaft 11 may be located at two sides of one end of the LED module 10, and the rotating shaft groove 21 is located at two sides of one end of the groove in the mounting seat 20, and is an arc-shaped groove body. In other embodiments, the setting positions of the rotating shaft 11 and the rotating shaft groove 21 can be changed appropriately, but it should be ensured that the rotating shaft 11 is disposed on the LED module 10, the rotating shaft groove 21 is disposed on the mounting base 20, and if the rotating shaft groove 21 is disposed on the LED module 10, the inward groove may affect the arrangement of the circuit structures in the LED module 10, so as to affect the normal use of the LED module 10.

In one embodiment, the elastic buckle 211 is disposed inside the rotating shaft groove 21, specifically, a square through hole is disposed in the inner bottom of the rotating shaft groove 21, and one end of the through hole extends inward, and the extending portion does not contact with the other inner walls except the connecting portion in the through hole, so as to form the elastic buckle 211.

Specifically, the rotating shaft 11 is provided with a plurality of clamping grooves 111. In this embodiment, a section of arc corresponding to an angle of approximately 300 ° of the axis may be taken out of the rotating shaft 11, eight evenly distributed clamping grooves 111 are provided in the section of arc, and the section of arc provided with the clamping grooves 111 may be toothed. When the LED module 10 rotates, the elastic buckle 211 on the mounting seat 20 is deformed under force and is disengaged from the clamping groove 111 on the rotating shaft 11, so that the rotating shaft 11 can rotate freely, and the angle is adjusted; when the gear is adjusted to a proper angle, the elastic buckle 211 clamps the clamping groove 111 of the rotating shaft 11, so that the LED module 10 is hovered and fixed.

Based on the above structure, the LED module 10 and the mounting seat 20 are connected and matched with the rotating shaft groove 21 through the rotating shaft 11, when the angle is adjusted, the rotating shaft 11 rotates in the rotating shaft groove 21 to change the included angle between the mounting seat 20 and the LED module 10, after the angle adjustment is completed, the elastic buckle 211 is clamped into the clamping groove 111 in the rotating shaft 11 through the elastic force, so that the angle adjustment and hovering function between the LED components are realized, and the problem that the LED module 10 cannot illuminate at multiple angles is solved.

Preferably, the elastic clasp 211 and the shaft slot 21 are integrally formed.

Referring to fig. 5, in the present embodiment, the elastic buckle 211 and the shaft slot 21 are made of elastic materials, such as plastic and other elastic materials. The elastic buckle 211 and the rotating shaft groove 21 may be formed by one-time processing, such as shaping by a specific mold, which is not limited herein.

Based on the above structure, since the elastic buckle 211 and the rotating shaft groove 21 have no spliced portion, breakage between the elastic buckle 211 and the rotating shaft groove 21 is not easy to occur, and stability of the structure is improved.

Example two

In the LED assembly angle adjusting structure 100 of the present embodiment, the elastic buckle 211 is a hook-shaped spring arm, and the end of the spring arm is rotationally clamped with the plurality of clamping grooves 111. The portion is provided with a hook 212.

Referring to fig. 1 and 5, in the present embodiment, the elastic buckle 211 is a hook-shaped spring arm, and a section of hook 212 bent into the slot 111 is disposed at one end far away from the connection of the elastic buckle 211. Specifically, the hook 212 is bent towards the axial direction of the rotating shaft 11, and the shape of the hook is adapted to the slot 111, so that the hook 212 can be smoothly clamped into the slot 111 during the clamping and matching. Meanwhile, the clamping hook 212 cannot shake in the clamping groove 111, so that hovering is more stable.

When adjusting the angle, it can be regarded that the mounting base 20 and the elastic buckle 211 disposed thereon are stationary, and the LED module 10 rotates relative to the mounting base 20 and drives the clamping groove 111 to rotate together, the clamping groove 111 generates a trend of separating from the matching position with the elastic buckle 211, at this time, the one end surface of the clamping hook 212 facing the rotation direction is elastically deformed by the pushing force exerted by the clamping groove 111 to slide to the top 1112 of the clamping groove 111 along the surface of the clamping groove 111, the pushing force disappears, the elastic buckle 211 returns by elastic deformation, and the clamping hook 212 slides to the next clamping groove 111 along the surface of the clamping groove 111.

After the angle of the LED module 10 is adjusted, the hook 212 slides into the bottom of one of the clamping grooves 111 along the outer surface of the rotating shaft 11 under the elastic action of the elastic buckle 211, so that the situation that the rotating shaft 11 slides automatically after the angle is adjusted is avoided.

Example III

In the LED module angle adjusting structure 100 of the present embodiment, both sides of the groove bottom 1111 and the groove top 1112 of the clamping groove 111 and/or the ends of the spring arms are rounded.

Referring to fig. 5, in the present embodiment, the clamping groove 111 may be in a shape of an elliptical groove body, one end close to the axis is closed, one end close to the outer side of the rotating shaft 11 is provided with an opening, the closed end is a groove bottom 1111, and a portion between the openings of adjacent clamping grooves 111 is a groove top 1112. The groove bottom 1111 and both side surfaces of the groove bottom 1111 are smooth arc surfaces.

Based on the above structure, when the rotating shaft 11 is in surface contact with the rotating shaft groove 21 during the angle adjustment process, the rotating shaft 11 is in surface contact, not in line contact, so that the friction loss between the rotating shaft 11 and the rotating shaft groove 21 is reduced, and the service life of the LED assembly angle adjustment structure 100 is prolonged. Meanwhile, the chamfer of the clamping groove 111 can enable the clamping hook 212 of the elastic clamp 211 to be easier when sliding out of the clamping groove 111, so that labor is saved when the LED module 10 is adjusted.

Example IV

The angle adjusting structure 100 of the LED assembly of this embodiment further has a lamp slot 22 for accommodating the LED module on the mounting base 20,

the rotating shaft groove 21 is positioned at two sides of one end of the lamp groove;

two elastic clips 211 are respectively provided in the two spindle grooves 21.

Referring to fig. 1 to 4, in the present embodiment, the lamp socket 22 may be a rectangular recess on a surface of the mounting base 20 near the LED module 10, for placing the LED module 10. Meanwhile, two sides of the lamp slot 22, which are close to one end of the rotating shaft 11, are respectively provided with an arc-shaped groove, which is used as the rotating shaft slot 21, and the inner sides of the grooves are respectively provided with an elastic buckle 211.

Specifically, one end of the lamp slot 22, which is close to the rotating shaft slot 21, is connected with the outside, the distance between two sides is larger than that between two sides of the LED module 10, and the slot length of the lamp slot 22 should be larger than that between two ends of the LED module 10.

Based on the above structure, after the portable power lighting device is used, the LED module 10 can be received in the lamp slot 22, so as to reduce the occupied space of the LED assembly angle adjusting structure 100 and improve portability.

Example five

The angle adjusting structure 100 of the LED assembly of the present embodiment, the rotating shaft groove 21 is provided with an opening for assembling the rotating shaft 11;

the size of the opening is smaller than the diameter of the rotating shaft.

Referring to fig. 1 and 4, in the present embodiment, an opening is provided on the shaft groove 21 to facilitate the installation of the shaft 11 into the shaft groove 21. The size of the opening is smaller than the diameter of the rotating shaft 11, so that the rotating shaft 11 is prevented from being separated from the rotating shaft groove 21 after being installed.

The pivot 11 is installed into in the pivot groove 21 from the opening part, and during the installation, the opening part takes place deformation, and the opening grow, holds pivot 11 and passes through from the opening part, installs the entry, and opening part deformation resumes, and the opening grow is little, avoids the pivot 11 after loading into to deviate from the opening part.

Preferably, the size of the opening is smaller than the diameter of the rotating shaft 11 and larger than the radius of the rotating shaft 11, so that the gap between the opening and the rotating shaft 11 is avoided, and when the opening of the rotating shaft 11 is deformed, the opening is deformed, and the rotating shaft groove 21 is broken.

Example six

The angle adjusting structure 100 of the LED assembly of the present embodiment, the rotation shaft groove 21 is elastically deformable.

In this embodiment, the shaft groove 21 can be elastically deformed, so that the shaft 11 can be conveniently installed. When the rotary shaft is assembled, the external force is applied to deform the rotary shaft groove 21, the rotary shaft 11 is assembled into the rotary shaft groove 21, after the rotary shaft is rotated, the external force is removed, the deformation of the rotary shaft groove 21 is recovered, and the rotary shaft 11 is prevented from being separated.

Based on the above structure, when the LED module 10 needs to be mounted or dismounted, an external force to the opening of the rotating shaft groove 21 can be applied to the rotating shaft 11, and the opening of the rotating shaft groove 21 is elastically deformed due to the extrusion of the rotating shaft 11, so that the distance between the openings can be larger than the diameter of the rotating shaft 11, and the rotating shaft 11 can enter the rotating shaft groove 21. After the rotary shaft 11 is installed, the external force is removed, and the opening of the rotary shaft groove 21 is restored, so that the opening can play a role in limiting the rotary shaft 11 from being separated from the rotary shaft groove 21. When the disassembly is needed, an external force is applied to the rotating shaft 11 to the opening of the rotating shaft groove 21, and the opening of the rotating shaft groove 21 is elastically deformed due to the extrusion of the rotating shaft 11, so that the distance between the openings can be larger than the diameter of the rotating shaft 11, and the rotating shaft 11 can be separated from the rotating shaft groove 21. After the rotating shaft 11 is separated, the external force is removed, and the opening of the rotating shaft groove 21 is restored, so that the opening can also play a role in facilitating the disassembly of the rotating shaft 11.
