Description

[Technical Field]

[0001] This invention relates to the technical field of toggle components and projection lamps having toggle components, and particularly to a toggle component for changing the position of a projection sheet. [Background Technology]

[0002] An existing projection lamp includes a housing, a light source assembly fixed to the housing, a tray member located above the light source assembly, a focusing lens located above the tray member, and a motor driving the tray member. The housing includes an outwardly extending slot, the tray member includes a tray and a projection disk mounted on the tray, the projection disk including a film, the tray being movably insertable into the slot, the motor driving the projection disk, and light emitted by the light source assembly passing through the film and projecting outwards.

[0003] Since the aforementioned projection lamp only creates a single rotating projection pattern without changing the content within the pattern, the projection effect is monotonous and cannot meet user needs. [Summary of the Invention]

[0004] In view of the problems faced by the prior art, the present invention provides a projection lamp with a gradually changing projection pattern.

[0005] To achieve the above objectives, the present invention employs the following technical means:

[0006] A toggle assembly, pivotally connected to a base, includes: a main body, a projection film mounted on the main body, a pivot extending from the main body, and an elastic member sleeved on the pivot. The pivot is mounted on the base, and the elastic member drives the projection film to move and reset, so that the projection film leaves the projection opening of the base.

[0007] Furthermore, 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 engaged upwards with the base, and the second end is engaged with the main body.

[0008] Furthermore, the first end protrudes upward into the slot of the base, and the second end protrudes downward into the recess of the main body, thereby moving the projection film.

[0009] Furthermore, during the insertion of a pushing component into the slot of the base, the toggle component is pushed from the first position to the second position, and the projection film is located above the projection port of the base.

[0010] A projection lamp includes: a base including a rearward through-hole; a light source assembly mounted on the base; a pushing assembly movably insertable into the slot and located above the light source assembly, the pushing assembly including a projection film; and a toggle assembly including a main body, the projection film mounted on the main body, a pivot extending from the main body, and an elastic member sleeved on the pivot, the pivot being pivotally connected to the base; when the pushing assembly is inserted forward into the slot, the pushing assembly pushes the toggle assembly from a first position to a second position, the projection film being located above the projection film; when the pushing assembly is withdrawn from the slot, the elastic member causes the toggle assembly to return to the first position, the projection film being moved away from the projection opening of the base.

[0011] Furthermore, the base includes a first seat and a second seat forming the slot, the second seat including a pivot groove that is vertically connected to the slot, and the pivot protruding into the pivot groove.

[0012] Furthermore, 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 engaged upwards with the first seat, and the second end is engaged with the main body.

[0013] Furthermore, the pushing component includes a base and an active part that protrudes upward relative to the base, the projection sheet is mounted on the base, and the actuating component includes a driven part that faces the pushing component, the active part driving the driven part to move.

[0014] Furthermore, the base includes an upward through-hole projection port, which is vertically connected to the slot. As the toggle component moves from the first position to the second position, the area of ​​the projection film covering the projection port continuously increases.

[0015] Furthermore, when the toggle is in the first position, the projection film is closer to the rear end of the slot relative to the projection port; when the toggle is in the second position, the projection film is located directly above the projection port.

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

[0017] A light source assembly is mounted on the base; a pushing assembly is movably inserted into a slot in the base and is located above the light source assembly, the pushing assembly including a projection sheet; a toggle assembly including a main body, the 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 pivotally connected to the base; when the pushing assembly is inserted forward into the slot, the pushing assembly pushes the toggle assembly from a first position to a second position, the projection sheet being located above the projection sheet; when the pushing assembly is withdrawn from the slot, the elastic member drives the toggle assembly to return to the first position, the projection sheet being away from the projection opening of the base, the toggle assembly can be used to block the projection pattern at different positions of the projection sheet, thereby continuously changing the projection pattern presented by the pushing assembly, enhancing the dynamic effect; in addition, different pushing assemblies can be replaced to push or not push the projection sheet, meeting the needs of diverse projection effects.

Detailed Implementation Methods

[0028] To facilitate a better understanding of the purpose, structure, features, and effects of this invention, the invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0029] like Figures 1 to 8 As shown, the projection lamp 100 of the present invention includes a housing 1, a base 2 mounted on the housing 1, a light source assembly 3 mounted on the base 2, a pushing assembly 4, a toggle assembly 5, a motor 6, and a projection lens 7.

[0030] like Figure 1 and Figure 2 As shown, the outer shell 1 includes an upper shell 11 and a lower shell 12 that are fixed to each other, a receiving cavity 13 formed by the upper shell 11 and the lower shell 12, and an insertion port 14 that communicates with the receiving cavity 13.

[0031] like Figure 2 , Figure 4 and Figure 5 As shown, the base 2 is housed within the receiving cavity 13. The base 2 includes a first seat 21, a second seat 22, and a slot 23 formed by the first seat 21 and the second seat 22, which are fixed to each other. 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 a plurality of fixing parts 214 arranged 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, a plurality of fixing posts 222 arranged around the projection opening 221, a pivot groove 223 extending upward, and a slot 224. The slot 224 is connected to the pivot groove 223 in the upper direction. The light-transmitting hole 212 is vertically aligned with the projection opening 221. The slot 23 is aligned with the insertion port 14 in the front-back direction. The projection opening 221 is vertically connected to the slot 23. Multiple fixing posts 222 are fixed to the fixing part 214 one-to-one. The light source assembly 3 is located directly below the light-transmitting hole 212, which is vertically connected to the slot 23. The pivot groove 223 is vertically connected to the slot 23.

[0032] like Figure 4 , Figure 5 and Figure 8As shown, the pushing component 4 is movably inserted into the slot 23 and protrudes rearward from the insertion port 14. The pushing component 4 includes a insertion plate 41 and a projection plate 42 mounted on the insertion plate 41. The insertion plate 41 includes a receiving groove 411 recessed downward from its top surface, and the projection plate 42 is mounted in the receiving groove 411. The projection plate 42 includes a base 421, a projection sheet 422 mounted on the base 421, and an active part 423 extending upward from the base 421, i.e., the active part 423 is positioned higher than the base 421. The active part 423 is located in front of the projection sheet 422, and in this embodiment, the active part 423 is arranged around the projection sheet 422. The motor 6 is mounted in the mounting hole 213 and has a gear protruding into the slot 23, the gear engaging with the gear ring of the projection plate 42.

[0033] like Figure 4 , Figure 5 , Figure 6 and Figure 8As shown, the actuating component 5 is connected to the base 2. The actuating component 5 is mounted on the second seat 22 and located above the pushing component 4. In this embodiment, the actuating component 5 is pivotally connected to the second seat 22. The actuating component 5 includes a main body 51, a driven part 52 extending downward from the main body 51, a projection film 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. That is, the driven part 52 is disposed downward toward the actuating component 5. The base 2 has a relief groove corresponding to the main body 51, that is, the main body 51 is at least partially exposed outward from the base 2. The main body 51 includes a recess 511 formed by recessing downward from its top surface, and the driven part 52 is located in front of the projection film 53. The projection lens 7 is located above the projection film 53 and is exposed upward through the projection port 221. The pattern of the projection sheet 422 is different from that of the projection film 53. The pivot 54 includes an upwardly penetrating shaft hole 541 and a stepped portion 542 surrounding the shaft hole 541. The pivot 54 protrudes into the pivot groove 223 and is positioned in the shaft hole 541 by a screw. The nut of the screw restricts the downward movement of the pivot 54. The pivot groove 223 has a first limiting portion that restricts the upward movement of the first stepped portion 542 and a second stepped portion that restricts the upward movement of the elastic member 55. The elastic member 55 includes a base 551, a first end portion 532 and a second end portion 533 extending from the base 551 in opposite directions. The first end portion 532 and the second end portion 533 are subjected to opposite forces. The base portion 551 is sleeved on the pivot 54, and the main body portion 51 restricts the downward movement of the base portion 551. The first end 532 engages upward with the slot 224, and the second end 533 engages downward with the recess 511, thereby moving and resetting the projection film 53. During the process of the pushing component 4 being inserted forward into the slot 23, the active part 423 first contacts the driven part 52, and the active part 423 pushes the driven part 52 forward, moving the actuating component 5 from a first position to a second position. The first position of the actuating component 5 is the state when the pushing component 4 is withdrawn from the slot 23, and the second position of the actuating component 5 is the state when the pushing component 4 is inserted into the slot 23. The angle of the actuating component 5 swinging from back to front is less than 90°, and the contact area between the active part 423 and the driven part 52 gradually increases from small to large, or the contact area between the active part 423 and the driven part 52 remains constant. When the pushing component 4 is in the first position, the projection of the pushing component 4 and the light-transmitting hole 212 in the vertical direction does not coincide.As the actuating component 5 moves from the first position to the second position, the area of ​​the projection film 53 blocking the projection opening 221 continuously increases until the projection sheet 422 and the projection film 53 overlap vertically. That is, when the pushing component 4 is in the second position, the central axis of the projection sheet 422 and the projection film 53 both coincide with the central axis of the light-transmitting hole 212. The actuating component 5 is located above the pushing component 4, and the motor 6 drives the pushing component 4 to rotate. Because the projection film 53 has irregular black light-blocking parts, as the pushing component 4 rotates, the actuating component 5 blocks different positions of the pushing component 4, thereby continuously changing the projection pattern presented by the pushing component 4. In other embodiments, the pushing component 4 and the actuating component 5 can cooperate to project a gradient moon projection effect. The projection sheet 422 has a light-transmitting area representing a full moon, and the projection film 53 has multiple light-blocking patterns, including multiple crescent moons of different structures and at least one full moon, all arranged along the moving trajectory of the full moon pattern on the projection sheet 422. As the projection sheet 422 rotates, the light-blocking patterns on the projection film 53 gradually block the patterns on the projection sheet 422 until the center of the full moon pattern on the projection sheet 422 coincides with the center of the light-blocking pattern of the full moon on the projection film 53, thus projecting the effect of a lunar eclipse.

[0034] In summary, the projection lamp of the present invention has the following beneficial effects:

[0035] (1) The push component 4 is movable and insertable into the slot 23 of the base 2 and is located above the light source component 3. The push component 4 includes a projection sheet 422. The toggle component 5 is movably connected to the base 2 and protrudes into the slot 23. The toggle component 5 includes a projection film 53. When the push component 4 is inserted forward into the slot 23, the push component 4 pushes the toggle component 5 from the first position to the second position. At this time, the projection film is located above the projection sheet. A motor 6 drives the push component 4 to rotate. As the push component 4 rotates, the toggle component 5 blocks different positions of the push component 4, thereby continuously changing the projection pattern presented by the push component 4. The dynamic sense of the projection image of the projection sheet is enhanced on the basis of rotation. In addition, the push component 4 can be replaced with a structure that does not trigger the movement of the toggle component 5 to realize the function of multiple projection effects sharing the same structure and improve the product utilization rate.
