Referring to fig. 1-3, one embodiment of a lamp assembly, at least, has a longer life. The lamp assembly comprises an angle adjusting structure 10 and a lamp source, wherein the angle adjusting structure 10 is used for installing the lamp source, and the lamp source is used for lighting, decorating and/or warning.
Referring to fig. 1 to 6, an angle adjustment structure 10 in an embodiment includes an outer frame 100 and an inner frame 200. The outer frame 100 is formed with a shaft hole 110, and the outer frame 100 is formed with outer teeth 120. The inner frame 200 includes a mounting frame 210 and a rotating shaft 220 disposed on the mounting frame 210, inner teeth 211 engaged with the outer teeth 120 are formed on the mounting frame 210, and the rotating shaft 220 is inserted into the shaft hole 110. Wherein the tooth grooves of the outer teeth 120 or the inner teeth 211 open in the axial direction of the rotating shaft 220.
During adjustment, external force is applied to rotate the rotating shaft 220 in the shaft hole 110, the mounting bracket 210, the internal teeth 211 formed on the mounting bracket 210 and the lamp source mounted on the mounting bracket 210 rotate together with the rotating shaft 220, and since the internal teeth 211 are meshed with the external teeth 120, the rotating angle of the lamp source can be accurately controlled by controlling the number of the rotating teeth, so that the irradiation area of the lamp source can be accurately controlled. Because the tooth space opening of the outer teeth 120 or the inner teeth 211 faces the axial direction of the rotating shaft 220, the outer teeth 120 do not need to bear the gravity of the lamp source, on one hand, the inner teeth 211 and the outer teeth 120 can rotate relatively by applying a small external force, and on the other hand, the outer teeth 120 are not easy to wear due to small stress on the outer teeth 120, so that the service life of the angle adjusting structure 10 is long.
In the embodiment, since the light source is mounted on the mounting frame 210, and the rotating shaft 220 disposed on the mounting frame 210 is inserted into the shaft hole 110, the gravity of the light source can be mainly borne by the wall of the shaft hole 110. The hole wall of the shaft hole 110 is relatively strong in bearing force and not easy to be damaged compared with the outer teeth 120.
The outer size of the end of the rotating shaft 220 far away from the mounting frame 210 is smaller than the outer size of the end of the rotating shaft 220 near the mounting frame 210. On the one hand, the outer contour dimension of the one end that the mounting bracket 210 was kept away from to pivot 220 is less relatively, and the ease that axle hole 110 was worn to establish to multiplicable pivot 220, and on the other hand, the outer contour dimension that pivot 220 is close to the one end of mounting bracket 210 is great relatively, can avoid pivot 220 excessively to penetrate in the axle hole 110 to avoid offering the face contact with axle hole 110 between the mounting bracket 210, prevent that mounting bracket 210 from being worn and torn. The end surface of the rotating shaft 220 is provided with lightening holes 221 penetrating through the rotating shaft 220 to lighten the load of the hole wall of the shaft hole 110. Of course, in other embodiments, the lightening holes 221 may be omitted. Alternatively, the lightening hole 221 does not penetrate the rotating shaft 220.
The number of teeth of internal tooth 211 is greater than or is less than the number of teeth of external tooth 120, and the number of teeth of a relatively less number of teeth in reducible internal tooth 211 and external tooth 120 to the preparation degree of difficulty and the cost of manufacture of a relatively less number of teeth in reduction internal tooth 211 and external tooth 120. In the present embodiment, the number of teeth of the internal teeth 211 is smaller than that of the external teeth 120, and the number of teeth of the internal teeth 211 may be one or at least two. In another embodiment, the number of teeth of the inner teeth 211 is greater than the number of teeth of the outer teeth 120, and the number of teeth of the outer teeth 120 may be one or at least two. Of course, in other embodiments, the number of teeth of the inner teeth 211 may be equal to the number of teeth of the outer teeth 120.
The outer frame 100 and/or the mounting frame 210 are annular frames, wherein the annular frames may be square annular frames, oval annular frames, or the like. When the outer frame 100 is a ring frame, it is convenient to place the mounting frame 210 in the space enclosed by the outer frame 100, so as to protect the mounting frame 210 to a certain extent. When the mounting frame 210 is an annular frame, the lamp can be conveniently placed in a space surrounded by the mounting frame 210, on one hand, the lamp can adapt to a cylindrical lamp source at a mounting position, and on the other hand, the lamp can be protected to a certain extent. In this embodiment, the outer frame 100 and the mounting frame 210 are both circular ring-shaped frame outer frames 100 and/or mounting frames 210. Of course, in other embodiments, only the outer frame 100 or only the mounting frame 210 may be an annular frame. Alternatively, the outer frame 100 and/or the mounting frame 210 are not annular frames, which can be flexibly designed according to practical situations.
Referring to fig. 7 to 9, when the outer frame 100 is a ring frame, the shaft hole 110 and the outer teeth 120 are distributed along the width direction of the outer frame 100, so that the mounting frame 210 can rotate from the initial position in opposite directions in one direction, the rotation angles in the two directions are substantially the same, and the lamp can extend out of the outer frame 100 along the outer frame 100. In this embodiment, the width direction of the outer frame 100 is the same as the length direction of the center line of the outer frame 100, when the mounting bracket 210 is at the starting position, the center line of the mounting bracket 210 is collinear with the center line of the outer frame 10, the rotation range of the mounting bracket 210 is 60 degrees, and the mounting bracket 210 can rotate at most 30 degrees clockwise and 30 degrees counterclockwise from the starting position. Of course, in other embodiments, the rotation range of the mounting bracket 210 can be flexibly adjusted, such as 50 degrees or 70 degrees, and the maximum angle of clockwise rotation of the mounting bracket 210 from the starting position may not coincide with the maximum angle of counterclockwise rotation of the mounting bracket 210 from the starting position.
Referring to fig. 4 to 6, the outer frame 100 further has a first stopper 130 and a second stopper 140 located at the periphery of the shaft hole 110, the mounting frame 210 has a protrusion 212 formed thereon, the protrusion 212 is located between the first stopper 130 and the second stopper 140, and the protrusion 212 can abut against the sidewall of the first stopper 130 and also abut against the sidewall of the second stopper 140. When the mounting bracket 210 rotates counterclockwise from the starting position to the maximum angle, the protrusion 212 can abut against the sidewall of the first stopper 130 to prevent the mounting bracket 210 from rotating counterclockwise. When the mounting bracket 210 rotates clockwise from the starting position to the maximum angle, the protrusion 212 can abut against the sidewall of the second stopper 140 to prevent the mounting bracket 210 from rotating clockwise. The rotation range of the mounting bracket 210 can be limited by the existence of the first stopper 130 and the second stopper 140.
In this embodiment, the protrusion 212 is rectangular, the protrusion 212 includes a first abutting surface 213 and a second abutting surface 214 that are disposed opposite to each other at an interval, the first abutting surface 213 is used for abutting against the first stopper 130, and the second abutting surface 214 is used for abutting against the second stopper 140. The first stopper 130 and the second stopper 140 are in the shape of long bar. Of course, in other embodiments, the shapes of the protrusion 212, the first stopper 130 and the second stopper 140 can be designed flexibly according to practical situations.
In this embodiment, the rotating shaft 220 is disposed on the protrusion 212, on one hand, the strength of the root portion of the rotating shaft 220 can be enhanced, and on the other hand, on the premise that the distance between the mounting frame 210 and the outer frame 100 is not changed, the length of the rotating shaft 220 can be reduced, thereby preventing the rotating shaft 220 from being easily broken due to the overlong rotating shaft 220 to a certain extent. The lightening holes 221 penetrate the protrusions 212 to lighten the overall weight of the angle adjusting structure 10. Of course, in other embodiments, the position of the rotation shaft 220 may be changed, such as above, below, left, or right of the protrusion 212. The lightening holes 221 may not extend through the protrusions 212.
In the axial direction of the rotating shaft 220, the meshing surface of the external teeth 120 is convex or concave relative to the opening surface of the shaft hole 110. This design allows the meshing surface of the external teeth 120 and the opening surface of the shaft hole 110 to be displaced in the axial direction of the rotary shaft 220, preventing damage to the meshing surface of the teeth or the opening surface of the shaft hole 110 during demolding. In the present embodiment, the meshing surface of the external teeth 120 is recessed with respect to the opening surface of the shaft hole 110 along the axial direction of the rotating shaft 220, and the opening surface of the shaft hole 110 is located between the meshing surface of the external teeth 120 and the mounting bracket 210.
The number of the shaft hole 110, the outer teeth 120, the rotation shaft 220, and the inner teeth 211 is two to improve the structural stability of the angle adjusting structure 10. In this embodiment, the two shaft holes 110 are coaxially disposed, the two rotating shafts 220 are respectively located at two opposite sides of the mounting frame 210, and are coaxially disposed, the two outer teeth 120 are respectively close to the two shaft holes 110, and the two inner teeth 211 are respectively engaged with the two outer teeth 120. Of course, in other embodiments, the number of the shaft hole 110, the outer teeth 120, the rotation shaft 220, or the inner teeth 211 may be one.
The lamp assembly and the angle adjustment structure 10 in the present embodiment have at least the following advantages:
(1) the use of elements such as screws, motors and the like can be avoided, and the cost is lower;
(2) the orientation of the light emitting surface of the light source can be accurately adjusted by designing the corresponding rotating angle of each tooth, so that the irradiation area of the light source can be accurately adjusted.
The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
