The motor drives the projection disc to rotate, and a film is disposed on the projection disc, with the focusing lens located above the film. The tray is movably insertable and removable in the slot, and the motor drives the projection disc.

[0003] Since the above-mentioned projection lamp only forms a single projection pattern that rotates continuously, but cannot change the content of the projection pattern, the projection effect is single and cannot meet user needs. [Utility Model Content]

[0004] In response to the problems faced by the background technology, the utility model provides a projection lamp with a gradually changing projection pattern.

[0005] In order to achieve the above purpose, the utility model adopts the following technical means:

[0006] A projection lamp comprises: a housing including a receiving cavity and a socket connected to the receiving cavity; a base mounted in the receiving cavity and including a slot extending outwardly therethrough; a light source assembly mounted on the base; a first projection assembly movably pluggable in the slot and located above the light source assembly, the first projection assembly including a first projection sheet; a second projection assembly connected to the base and protruding into the slot, the second projection assembly including a second projection sheet, the first projection sheet and the second projection sheet having different patterns, and when the first projection assembly is inserted forward into the slot, the second projection sheet is located above the first projection sheet, a motor drives the first projection assembly to rotate, and as the first projection assembly rotates, the second projection sheet blocks different positions of the first projection sheet, thereby continuously changing the projection pattern presented by the first projection sheet.

[0007] Furthermore, when the first projection assembly is inserted forward into the slot, the first projection assembly pushes the second projection assembly from the first position to the second position. At this time, the second projection assembly is located above the first projection assembly.

[0008] Furthermore, the first projection assembly includes a base and an active portion protruding upward relative to the base, the first projection sheet is installed on the base, and the second projection assembly includes a driven portion arranged toward the first projection assembly, and the active portion drives the driven portion to move.

[0009] Furthermore, the active part pushes the driven part to move forward, and when the second projection assembly moves from the first position to the second position, the contact area between the active part and the driven part gradually increases from small to large or the contact area remains unchanged.

[0010] Furthermore, the base includes an upwardly penetrating projection port, which is connected to the slot in vertical communication. When the second projection assembly moves from the first position to the second position, the area of ​​the projection port blocked by the second projection sheet continuously increases.

[0011] Furthermore, the second projection assembly is pivotally connected to the base. When the first projection assembly is inserted into the slot, the second projection assembly swings from back to front at an angle less than 90°.

[0012] Furthermore, the second projection assembly includes a main body, the second projection sheet mounted on the main body, a pivot extending from the main body, and an elastic member sleeved on the pivot, the pivot being mounted on the base, and the elastic member driving the second projection sheet to reset.

[0013] Furthermore, the base includes a first seat and a second seat forming the slot, the second seat includes a pivot groove connected to the slot up and down, the pivot protrudes into the pivot groove, the elastic member includes a base and a first end and a second end extending from the base in opposite directions, the first end and the second end are subjected to opposite forces, the first end is upwardly clamped to the first seat, and the second end is clamped to the main body.

[0014] Furthermore, the first end protrudes upward into the slot of the first seat, the slot is communicated with the pivoting slot, and the second end protrudes downward into the recess of the main body to drive the second slide to move.

[0015] Furthermore, the base includes a light-transmitting hole extending vertically therethrough, the light-transmitting hole being connected to the slot. When the first projection assembly is in the first position, projections of the first projection assembly and the light-transmitting hole in the vertical direction do not overlap.

[0016] Compared with the prior art, the projection lamp of the present invention has the following beneficial effects:

[0017] The first projection assembly can be movably inserted and removed from the slot of the base and is located above the light source assembly. The first projection assembly includes a first projection sheet; the second projection assembly is connected to the base and protrudes into the slot. The second projection assembly includes a second projection sheet. The patterns of the first projection sheet and the second projection sheet are different. When the first projection assembly is inserted forward into the slot, the second projection sheet is located above the first projection sheet. A motor drives the first projection assembly to rotate. As the first projection assembly rotates, the second projection sheet blocks different positions of the first projection sheet, thereby continuously changing the projection pattern presented by the first projection sheet, enhancing the dynamic sense of the projection picture of the first projection sheet on the basis of only rotation, changing the light and dark positions of the projection, or changing the projection picture.

[0028] [Specific implementation method]

[0029] In order to facilitate a better understanding of the purpose, structure, features and effects of the present invention, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods.

[0030] like Figures 1 to 8 As shown, the projection lamp 100 of the present invention includes a housing 1, a base 2 installed on the housing 1, a light source assembly 3 installed on the base 2, a first projection assembly 4, a second projection assembly 5, a motor 6 and a projection lens 7.

[0031] like Figure 1 and Figure 2 As shown, the housing 1 includes an upper shell 11 and a lower shell 12 fixed to each other, a receiving cavity 13 formed by the upper shell 11 and the lower shell 12 , and a socket 14 communicating with the receiving cavity 13 .

[0032] like Figure 2 、 Figure 4 and Figure 5 As shown, the base 2 is housed in the housing cavity 13. The base 2 includes a first seat 21 and a second seat 22 fixed to each other, and a slot 23 formed by the first and second seats 21 and 22. The first seat 21 includes a groove 211 formed downward from its top surface, a light-transmitting hole 212 extending upward through the bottom wall of the groove 211, a mounting hole 213, and multiple fixing portions 214 disposed around the groove 211. The mounting hole 213 is located in front of the light-transmitting hole 212. The second seat 22 includes a projection opening 221 extending vertically through the base 221, multiple fixing posts 222 disposed around the projection opening 221, a pivoting slot 223 extending upward through the base 221, and a latching slot 224. The latching slot 224 is connected to the pivoting slot 223 in the forward direction. The light-transmitting hole 212 is aligned vertically with the projection opening 221. The slot 23 is aligned front-to-back with the socket 14. The projection opening 221 is connected vertically to the slot 23. The plurality of fixing posts 222 are fixed to the fixing portion 214 in a one-to-one correspondence. The light source assembly 3 is located directly below the light-transmitting hole 212, which is vertically connected to the slot 23. The pivoting slot 223 is vertically connected to the slot 23.

[0033] like Figure 4 、 Figure 5 and Figure 8As shown, the first projection assembly 4 can be movably inserted and removed from the slot 23 and protrudes rearwardly from the socket 14. The first projection assembly 4 includes an insertion tray 41 and a projection tray 42 mounted on the insertion tray 41. The insertion tray 41 includes a receiving groove 411 formed by a downward recess from its top surface, and the projection tray 42 is mounted in the receiving groove 411. The projection tray 42 includes a base 421, a first projection sheet 422 mounted on the base 421, and an active portion 423 extending upward from the base 421, that is, the active portion 423 is arranged higher than the base 421. The active portion 423 is located in front of the first projection sheet 422. In this embodiment, the active portion 423 is arranged around the first projection sheet 422. The motor 6 is mounted in the mounting hole 213 and is provided with a gear that protrudes into the slot 23. The gear cooperates with the ring gear of the projection tray 42.

[0034] like Figure 4 、 Figure 5 、 Figure 6 and Figure 8As shown, the second projection assembly 5 is connected to the base 2. The second projection assembly 5 is mounted on the second seat 22 and located above the first projection assembly 4. In this embodiment, the second projection assembly 5 is pivotally connected to the second seat 22. The second projection assembly 5 includes a main body 51, a follower portion 52 extending downward from the main body 51, a second projection sheet 53 mounted on the main body 51, a pivot 54 extending upward from the main body 51, and an elastic member 55 sleeved on the pivot 54. In other words, the follower portion 52 is positioned downward toward the second projection assembly 5. The base 2 has a recess corresponding to the main body 51, allowing the main body 51 to at least partially protrude from the base 2. The main body 51 includes a recess 511 recessed downward from its top surface. The follower portion 52 is located in front of the second projection sheet 53. The projection lens 7 is located above the second projection sheet 53 and protrudes upward from the projection opening 221. The first projection sheet 422 and the second projection sheet 53 have different patterns. The pivot 54 includes an upwardly extending axial hole 541 and a stepped portion 542 surrounding the axial hole 541. The pivot 54 protrudes into the pivot slot 223 and is secured to the axial hole 541 by a screw. The screw's nut restricts downward movement of the pivot 54. The pivot slot 223 is provided with a first stopper to restrict upward movement of the first stepped portion 542, and a second step to restrict upward movement of the elastic member 55. The elastic member 55 includes a base 551, a first end 532 and a second end 533 extending in opposite directions from the base 551. The first end 532 and the second end 533 are subjected to opposite forces. The base 551 is sleeved around the pivot 54, and the main body 51 restricts downward movement of the base 551. The first end 532 engages upwardly with the engaging slot 224, while the second end 533 engages downwardly with the recess 511, thereby driving the second slide 53 to move and return to its original position. During the forward insertion of the first projection assembly 4 into the slot 23, the active portion 423 first contacts the passive portion 52. The active portion 423 pushes the passive portion 52 forward, moving the second projection assembly 5 from a first position to a second position. The first position of the second projection assembly 5 corresponds to the state when the first projection assembly 4 is removed from the slot 23, while the second position corresponds to the state when the first projection assembly 4 is inserted into the slot 23. The angle of the second projection assembly 5 swinging from back to front is less than 90°, and the contact area between the active portion 423 and the passive portion 52 gradually increases or remains constant. When the first projection assembly 4 is in the first position, the vertical projection of the first projection assembly 4 and the light-transmitting aperture 212 do not overlap.As the second projection assembly 5 moves from the first position to the second position, the area of ​​the projection opening 221 obscured by the second projection sheet 53 continuously increases until the first projection sheet 422 and the second projection sheet 53 vertically overlap. Specifically, when the first projection assembly 4 is in the second position, the central axes of the first projection sheet 422 and the second projection sheet 53 both overlap with the central axis of the light-transmitting hole 212. The second projection assembly 5 is positioned above the first projection assembly 4. The motor 6 drives the first projection assembly 4 to rotate. Because the second projection sheet 53 is provided with irregular black light-blocking portions, as the first projection assembly 4 rotates, the second projection assembly 5 blocks different portions of the first projection assembly 4, thereby continuously changing the projection pattern presented by the first projection assembly 4. In other embodiments, the first projection assembly 4 and the second projection assembly 5 can cooperate to project a gradually changing moon projection effect. The first projection sheet 422 is provided with a light-transmitting area of ​​a full moon, and the second projection sheet 53 is provided with multiple light-shielding patterns. The patterns include multiple crescent moons of different structures and at least one full moon, all of which are arranged along the moving trajectory of the full moon pattern on the first projection sheet 422. During the rotation of the first projection sheet 422, the light-shielding pattern on the second projection sheet 53 gradually blocks the pattern on the first projection sheet 422 until the full moon pattern on the first projection sheet 422 and the light-shielding pattern of the full moon on the second projection sheet 53 coincide with the center, thereby projecting the effect of a lunar eclipse.

[0035] In summary, the projection lamp of the present invention has the following beneficial effects:

[0036] (1) A first projection assembly can be movably inserted into a slot of the base and is located above the light source assembly, the first projection assembly includes a first projection sheet; a second projection assembly is connected to the base and protrudes into the slot, the second projection assembly includes a second projection sheet, the patterns of the first projection sheet and the second projection sheet are different, when the first projection assembly is inserted forward into the slot, the second projection sheet is located above the first projection sheet, a motor drives the first projection assembly to rotate, as the first projection assembly rotates, the second projection sheet blocks different positions of the first projection sheet, thereby continuously changing the projection pattern presented by the first projection sheet, enhancing the dynamic sense of the projection picture of the first projection sheet on the basis of only rotation, changing the light and dark position of the projection, or changing the projection picture.
