DETAILED DESCRIPTION

[0027] Embodiments of the present application are described below in detail, examples of which are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and cannot be understood as limiting the present application.

[0028] The present application relates to a cylinder spotlight, comprising a cylinder seat 100, a light source member 200, a support member 300 and a turning member 400.

[0029] As Figure 1 , Figure 3 and Figure 4As shown, the lamp source member 200, the support member 300 and the turning member 400 can be installed inside the barrel base 100. The inside of the support member 300 is hollow in a spherical shape, and the inner wall of the support member 300 forms an inner spherical surface 310. The outer wall of the support member 300 is not limited in shape, and can be set in a corresponding spherical shape, or in a cylindrical shape or other shapes. The support member 300 can be a separate component, and is fixed in the barrel base 100 by means of screws, glue, clamping or other means, or can be integrally formed in the barrel base 100. The outer contour of the turning member 400 is spherical, and the outer wall of the turning member 400 is an outer spherical surface 410. The turning member 400 is installed in the support base, and the sphere center of the outer spherical surface 410 coincides or nearly coincides with the sphere center of the inner spherical surface 310. The turning member 400 can rotate relative to the support member 300, and the rotation mode is universal rotation. Exemplarily, taking one axis A of the inner spherical surface 310 passing through the sphere center thereof and one axis B of the outer spherical surface 410 passing through the sphere center thereof as examples, as shown in FIG. 2, the axis A and the axis B are in a coinciding position, and the turning member 400 can rotate coaxially around the axis A / B; as shown in FIG. 3, the axis A and the axis B are in a non-coinciding position, and the turning member 400 can rotate around the axis A / B in a non-coaxial mode. Figure 1 As shown, the axis A and the axis B are in a coinciding position, and the turning member 400 can rotate coaxially around the axis A / B; as shown in FIG. 3, the axis A and the axis B are in a non-coinciding position, and the turning member 400 can rotate around the axis A / B in a non-coaxial mode. Figure 2As shown, the turning piece 400 can be deflected in the direction gradually deviating from the axis A to the axis B, and then rotated around the axis A. The turning piece 400 can be provided in a hollow structure or a hollowed structure. The light source piece 200 can be a lamp panel integrated with a lamp bead. The light source piece 200 can be fixed in the cylinder seat 100 or fixed on the turning piece 400. The light source piece 200 projects light outward through the turning piece 400. One of the outer spherical surface 410 and the inner spherical surface 310 is provided with a plurality of clamping grooves 510, and the other is provided with a clamping convex 520. That is, the plurality of clamping grooves 510 can be provided on the outer spherical surface 410, and the clamping convex 520 can be provided on the inner spherical surface 310; or the plurality of clamping grooves 510 can be provided on the inner spherical surface 310, and the clamping convex 520 can be provided on the outer spherical surface 410. The clamping convex 520 can be integrally formed on the inner spherical surface 310 / outer spherical surface 410 or mounted on the inner spherical surface 310 / outer spherical surface 410 as a separate component. The clamping convex 520 can be provided in a cylindrical structure or a spherical structure. The clamping convex 520 is configured to slide or switch into different clamping grooves 510 according to the rotation direction of the turning piece 400 relative to the support piece 300. For example, when the turning piece 400 rotates around the axis A, the clamping convex 520 is clamped in one of the clamping grooves 510 and slides in the clamping groove 510. When the turning piece 400 is deflected in the direction gradually deviating from the axis A to the axis B, the clamping convex 520 slides out of the current clamping groove 510 and switches into another clamping groove 510, that is, the clamping convex 520 switches into different clamping grooves 510 according to the deflection position of the turning piece 400. Similarly, when the turning piece 400 is deflected in the direction gradually deviating from the axis A to the axis B, the clamping convex 520 is clamped in one of the clamping grooves 510 and slides in the clamping groove 510 according to the rotation of the turning piece 400. When the turning piece 400 rotates around the axis A, the clamping convex 520 slides out of the current clamping groove 510 and switches into another clamping groove 510, that is, the clamping convex 520 switches into different clamping grooves 510 according to the deflection position of the turning piece 400. The movement of the clamping convex 520 relative to the clamping groove 510 is determined according to the setting direction and distribution position of the clamping grooves 510 on the inner spherical surface 310 or the outer spherical surface 410. By changing the position of the turning piece 400, the projection range and angle of the light source piece 200 can be changed. By using the cooperation of the clamping convex 520 and the clamping groove 510, the multi-angle position transformation of the turning piece 400 is realized, and the movement of the turning piece 400 is guided and limited, that is, the turning piece 400 can be stably positioned in the current clamping groove 510 even if it is shaken.

[0030] In an embodiment, as shown in FIG. 1, Figure 3 and Figure 4As shown, the protrusion 520 is disposed on the outer spherical surface 410. When the protrusion 520 switches positions between different slots 510, it can elastically move relative to the outer spherical surface 410. It can be understood that the protrusion 520 can be configured to achieve elastic movement relative to the outer spherical surface 410 through its own material properties. For example, the protrusion 520 may be made of silicone or rubber and disposed on the outer spherical surface 410. The protrusion 520 itself has a certain elastic deformation capability, and when switching positions between different slots 510, it undergoes elastic deformation due to the resistance of the slots 510. Alternatively, the entire outer spherical surface 410 or a local area where the protrusion 520 is located can undergo elastic deformation when subjected to external force, thereby causing the protrusion 520 to elastically move along with a local area of ​​the outer spherical surface 410 when subjected to external force. This can prevent excessive resistance when the protrusion 520 switches between different slots 510, thus avoiding increased wear.

[0031] Based on the previous embodiment, such as Figure 4 As shown, the steering component 400 has a spherical shell wall 420. That is, the interior of the steering component 400 is also a spherical cavity. The outer surface of the shell wall 420 forms an outer spherical surface 410. Two through slots 421 are formed on the shell wall 420. The shell wall 420 between the two through slots 421 forms an elastic wall 422. A locking protrusion 520 is provided on the elastic wall 422. It can be understood that the elastic wall 422 bulges outward in an arc-shaped plate on the steering component 400. When the locking protrusion 520 switches between different locking slots 510, the locking protrusion 520 is subjected to external force, and the elastic wall 422 elastically deforms towards the interior of the steering component 400, thereby realizing the movement of the locking protrusion 520 relative to the outer spherical surface 410. When the locking protrusion 520 enters the locking slot 510, the elastic wall 422 elastically returns to its original position, while keeping the locking protrusion 520 locked in the current locking slot 510. Furthermore, multiple elastic walls 422 can be provided on the shell wall 420, and each elastic wall 422 has a locking protrusion 520. The stability of the steering component 400 is further improved by the cooperation of multiple locking protrusions 520 with the locking groove 510. The locking protrusions 520 can be randomly distributed on the outer spherical surface 410. Alternatively, the locking protrusions 520 can be located on the same circumference of the cross-section passing through the center of the outer spherical surface 410.

[0032] Based on any of the above embodiments, the inner spherical surface 310 or the outer spherical surface 410 is provided with a plurality of convex ribs 320 arranged in a circular ring shape around the same central axis and sequentially and spacedly arranged, and a clamping groove 510 is formed between two adjacent convex ribs 320. In this embodiment, the clamping convex 520 is arranged on the outer spherical surface 410, and the clamping groove 510 is arranged on the inner spherical surface 310. A plurality of convex ribs 320 are arranged on the inner spherical surface 310, and each convex rib 320 is arranged around the axis A, that is, each clamping groove 510 is formed around the axis A. When the steering member 400 rotates around the axis A, each clamping convex 520 slides along the currently aligned clamping groove 510. When the steering member 400 rotates in a direction gradually deviated from the axis A with respect to the axis B, the clamping convex 520 slides out of the current clamping groove 510 and slides into the adjacent clamping groove 510 after passing through the convex rib 320.

[0033] Based on any of the above embodiments, as shown in Figure 1 、 Figure 2 and Figure 4 , the inside of the steering member 400 is hollow to form a light guide cavity 430. The light guide cavity 430 is provided with a first through port 431 and a second through port 432. The first through port 431 and the second through port 432 are coaxially arranged. In this embodiment, the central axis of the first through port 431 and the second through port 432 is the axis B. The light source member 200 emits light from the first through port 431 to the second through port 432. By changing the position of the steering member 400, the projection direction of the second through port 432 is changed.

[0034] Based on the above embodiment, as shown in Figure 1 、 Figure 3 、 Figure 4 and Figure 5As shown, the support member 300 has a third through-hole 330 and a fourth through-hole 340. The third through-hole 330 and the fourth through-hole 340 are coaxially arranged. In this embodiment, the central axis of the third through-hole 330 and the fourth through-hole 340 is axis A. In the direction shown in the figure, the first through-hole 431 is located above the second through-hole 432, and the third through-hole 330 is located above the fourth through-hole 340. The outer side of the first through-hole 431 extends a first extension wall 440 radially toward the inner spherical surface 310 along the outer spherical surface 410. The inner side of the third through-hole 330 extends a second extension wall 350 radially toward the outer spherical surface 410 along the inner spherical surface 310. When the rotating member rotates to the position where the first through-hole 431 and the third through-hole 330 coincide with the central axis, that is, when axis A coincides with axis B, a first gap 610 is formed between the first extension wall 440 and the second extension wall 350. The outer edge of the first extension wall 440 has a first side 441 and a second side 442, with the second side 442 being closer to the second opening 432 than the first side 441, i.e., the first side 441 is located above the second side 442 in the illustrated direction. The outer edge of the second extension wall 350 has a third side 351 and a fourth side 352, with the fourth side 352 being closer to the fourth opening 340 than the third side 351, i.e., the third side 351 is located above the fourth side 352 in the illustrated direction. The diameter of the circumference containing the second side 442 is larger than the diameter of the circumference containing the third side 351. It can be understood that when axis A coincides with axis B, the first side 441 is opposite to the third side 351, and the second side 442 is opposite to the fourth side 352, forming a first gap 610 between the first extension wall 440 and the second extension wall 350. When the steering component 400 is moved upward relative to the support component 300 along axis A, the third side 351 will restrict the upward movement of the second side 442. That is, the second extension wall 350 restricts the first extension wall 440, preventing the first opening 431 from completely dislodging upward from the third opening 330. When the rotating component rotates from the position where axis A coincides with axis B to the direction of axis B deviating from axis A, a relatively large external force is applied to the rotating component, which allows a portion of the first extension wall 440 to pass upward over the second extension wall 350, thus causing a portion of the first opening 431 to extend upward out of the third opening 330, thereby deflecting the rotating component.

[0035] Furthermore, such as Figure 5 As shown, a second gap 620 is formed between the inner spherical surface 310 and the outer spherical surface 410. The minimum spacing dimension of the second gap 620 is greater than the spacing dimension of the first gap 610. The minimum spacing dimension of the second gap 620 is the spacing dimension between the rib 320 and the outer spherical surface 410. When the rotating member deflects relative to the support member 300, the rib 320 will not interfere with the first extension wall 440.

[0036] In one embodiment, such as Figure 1 and Figure 2As shown, the second through hole 432 is provided with a lens 700. The barrel 100 is provided with a boss 110. The light source 200 can be fixedly installed on the boss 110 by means of adhesive, screw locking or the like. The boss 110 extends into the turning piece 400, that is, the light source 200 is located in the inner cavity of the turning piece 400. By selecting different lenses 700 and changing the position of the turning piece 400, the range, angle or brightness of light projection can be changed to meet different lighting needs of users.
