Description

Technical Field

[0001] This utility model relates to the field of projection equipment, specifically to a projection lamp. Background Technology

[0002] As a core component of modern projection technology, the principle of a projection lamp is to emit a light beam through a light source, which is then modulated by an optical system to make an image printed on a projection film or film into a projection disk. The image is then magnified by optical projection and projected onto a wall, screen, or ceiling, thus being widely used in various occasions such as interior decoration, advertising projection, and event promotion.

[0003] To facilitate changing the projected content, existing projector lamps generally have a pluggable projection disc. For example, Chinese utility model patent application number CN202421548726.4 discloses a non-transparent lampshade dynamic projection lamp. It has a plug disc on which a projection turntable is rotatably supported. The mounting groove of the plug disc has a notch. The projection turntable includes a gear disk and a projection sheet. When the plug disc is slidably inserted into the socket, the drive gear is located in the notch and meshes with the gear disk. The motor drives the drive gear to rotate, which in turn drives the gear disk to rotate, and finally drives the projection sheet to rotate, forming a dynamic projection. When it is necessary to change the projected pattern, the plug disc can be directly pulled out to replace the projection sheet. However, in the aforementioned projection lamp, the drive gear is located directly in front of the insertion / removal direction of the insert plate. When the insert plate is inserted into the socket, the tip of the drive gear may abut against the tip of the gear plate, preventing the insert plate from being inserted into the preset position and the drive gear from meshing with the gear plate, thus affecting the transmission and preventing the projection sheet from rotating and dynamically projecting. In addition, such a design also restricts the position and layout of the notch, drive gear, motor, and other structures, thereby limiting the product's shape and making it difficult to expand the product's appearance design in different product forms.

[0004] Therefore, it is necessary to develop a projection lamp that can effectively ensure proper engagement and has a more flexible layout. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model proposes a projection lamp that can effectively ensure proper engagement and has a more flexible layout.

[0006] The technical solution of this utility model is implemented as follows:

[0007] A projection lamp, comprising:

[0008] A pull-out positioning component, wherein an imaging lens module and an illumination lens module are respectively provided on both sides of the pull-out positioning component, and a light source is provided on the side of the illumination lens module away from the pull-out positioning component.

[0009] A pull-out tray, wherein the pull-out tray is engaged with a pull-out positioning component, and a gear disk is rotatably mounted on the pull-out tray, and a projection disk is mounted on the gear disk;

[0010] The gear power device, when the pull-out disc is inserted into the pull-out positioning member, the output wheel of the gear power device meshes with the gear disc, and the output wheel of the gear power device is located on the oblique side of the gear disc.

[0011] Furthermore, when the gear power device meshes with the gear disk, the line connecting the meshing point of the two to the center of the gear disk has a non-zero angle with the insertion / removal direction of the pull-out disk.

[0012] Furthermore, the gear power device includes a drive motor and a transmission gear, wherein the input end of the transmission gear is connected to the output shaft of the drive motor and the output end of the transmission gear meshes with a gear disk.

[0013] Furthermore, the transmission gear includes a driving gear, which is fixedly connected to the output shaft of the drive motor, and the driving gear meshes with a gear disk through at least one driven gear.

[0014] Furthermore, the pull-out plate includes a pull-out plate groove, a pull-out handle is provided on one side of the pull-out plate groove and a notch is provided on the other side of the pull-out plate groove. The notch is located on the oblique side of the pull-out plate groove. When the pull-out plate is inserted into the pull-out positioning member, a part of the output end of the transmission gear is located in the notch and meshes with the gear disk. In addition, a light-transmitting hole is provided in the center of the pull-out plate groove.

[0015] Furthermore, the pull-out positioning component includes a tray, both sides of which are provided with retaining edges and a central through hole. The tray also has at least one locking protrusion, which engages with the pull-out tray when the gear power device meshes with the gear disk.

[0016] Furthermore, the projection disk includes a projection disk shell, which is fitted inside the gear disk. A projection film is sandwiched inside the projection disk shell, and light-transmitting openings are provided on both the upper and lower sides of the projection disk shell. The two light-transmitting openings and the projection film are coaxial.

[0017] Furthermore, the projection disk housing has a notch along its edge, and the gear disk has a protrusion along its inner edge. When the projection disk is placed inside the gear disk, the notch and the protrusion engage.

[0018] Furthermore, the projection disc housing includes an upper shell and a lower shell, wherein a pin is provided on the bottom surface of the upper shell and a pin hole is provided on the lower shell. When the pin is inserted into the pin hole, the upper shell and the lower shell cooperate to form a cavity for accommodating and fixing the projection film.

[0019] Furthermore, it also includes a lamp housing, in which the pull-out positioning component, imaging lens module, illumination lens module, light source, and gear power device are all housed. Additionally, a socket is provided on one side of the lamp housing, which is connected to the pull-out positioning component.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] This invention, by setting a pull-out plate and a pull-out positioning component, allows the gear disk and projection disk on the pull-out plate to simultaneously enter the pull-out positioning component when the pull-out plate is inserted into the pull-out positioning component, until the output wheel of the gear power device meshes with the gear disk. During this process, since the output wheel of the gear power device is located on the oblique side of the gear disk, when the teeth on the output wheel of the gear power device contact the teeth on the gear disk, they will rotate, thereby avoiding the situation where the tooth tips of the two abut each other, effectively ensuring that the output wheel of the gear power device and the gear disk are properly meshed. In addition, setting the output wheel of the gear power device on the oblique side of the gear disk also frees the output wheel of the gear power device from the traditional constraint that it must be located directly in front of the pull-out plate's forward direction, making the layout more flexible and allowing for more choices in product form design.

[0034] Reference Figures 1-6

[0035] A projection lamp, comprising:

[0036] A pull-out positioning component 3 is provided with an imaging lens module 1 and an illumination lens module 2 respectively on both sides of the pull-out positioning component 3. A light source 4 is provided on the side of the illumination lens module 2 away from the pull-out positioning component 3.

[0037] A pull-out tray 5 is engaged with a pull-out positioning component 3, and a gear disk 6 is rotatably mounted on the pull-out tray 5, with a projection disk 7 mounted on the gear disk 6.

[0038] When the pull-out disc 5 is inserted into the pull-out positioning member 3, the output wheel of the gear power device 8 meshes with the gear disk 6, and the output wheel of the gear power device 8 is located on the oblique side of the gear disk 6.

[0039] When the pull-out plate 5 is inserted into the pull-out positioning piece 3, the gear plate 6 and the projection plate 7 set on the pull-out plate 5 enter the pull-out positioning piece 3 simultaneously until the output wheel of the gear power device 8 meshes with the gear plate 6. The light emitted by the light source 4 will pass through the illumination lens module 2, the pull-out positioning piece 3, the pull-out plate 5, the gear plate 6, the projection plate 7, and the imaging lens module 1 in sequence, and finally project the image printed on the projection plate 7 onto a flat surface such as a wall, screen, or ceiling.

[0040] During the process of the gear disk 6 moving to mesh with the output wheel of the gear power device 8, since the output wheel of the gear power device 8 is located on the oblique side of the gear disk 6, that is, when the gear power device 8 and the gear disk 6 mesh, the line connecting the meshing point of the two to the center of the gear disk 6 has a non-zero angle with the insertion and removal direction of the pull-out plate 5. When the teeth on the output wheel of the gear power device 8 contact the teeth on the gear disk 6, they will rotate, thereby avoiding the situation where the tooth tips of the two abut each other, effectively ensuring that the output wheel of the gear power device 8 and the gear disk 6 are properly meshed. In addition, setting the output wheel of the gear power device 8 on the oblique side of the gear disk 6 also frees the output wheel of the gear power device 8 from the traditional constraint that it must be located directly in front of the forward direction of the pull-out plate 5, making the layout more flexible and allowing for more choices in product form design.

[0041] In some preferred embodiments, the non-zero included angle is an acute angle.

[0042] like Figure 3 and Figure 4 As shown, the gear power device 8 includes a drive motor 81 and a transmission gear 82. The input end of the transmission gear 82 is connected to the output shaft of the drive motor 81, and the output end of the transmission gear 82 meshes with the gear disk 6.

[0043] In one embodiment, the transmission gear 82 is a gear. In this case, the transmission gear 82 receives the power input from the drive motor 81 and outputs the power to the gear disk 6, driving the gear disk 6 to rotate.

[0044] In another embodiment, the transmission gear 82 includes a drive gear 821, which is fixedly connected to the output shaft of the drive motor 81. The drive gear 821 meshes with the gear disk 6 through at least one driven gear 822. The number of teeth on the drive gear 821 and the driven gear 822 are not equal, thereby achieving the effect of deceleration or acceleration. This allows the projection speed to be unrestricted by the output speed of the drive motor 81, thus enabling the use of different types of motors. Furthermore, in this embodiment, the driven gear 822 meshing with the gear disk 6 is the output wheel of the gear power device 8 and is located on the oblique side of the gear disk 6. This allows for a more flexible layout of the drive gear 821 and the driven gear 822. Especially when multiple driven gears 822 are used for speed change, the drive gear 821 and the multiple driven gears 822 do not need to be arranged in a straight line along the insertion and removal direction of the gear disk 6, which can effectively save space, make the structure more compact and concentrated, reduce the limitations on the subsequent projection lamp product form design, and is more conducive to the expansion of product appearance design.

[0045] like Figure 5 As shown, the pull-out plate 5 includes a pull-out plate groove 51, and the gear disk 6 is positioned in the pull-out plate groove 51, so that the gear disk 6 can rotate within the pull-out plate groove 51. When the pull-out plate 5 is inserted or removed, it can drive the gear disk 6 and the projection disk 7 to move synchronously. A pull-out handle 53 is provided on one side of the pull-out plate groove 51, and a notch 52 is provided on the other side of the pull-out plate groove 51. The notch 52 is located on the oblique side of the pull-out plate groove 51. When the pull-out plate 5 is inserted into the pull-out positioning member 3, a portion of the output end of the transmission gear 82 is located in the notch 52 and meshes with the gear disk 6, thereby driving the gear disk 6 to rotate axially within the pull-out plate groove 51. Furthermore, a light-transmitting hole 54 is provided in the center of the pull-out plate groove 51, and light can enter the gear disk 6 and the projection disk 7 through the central through hole 34.

[0046] like Figure 3 and Figure 4 As shown, the pull-out positioning component 3 includes a tray 31. Both sides of the tray 31 are provided with retaining edges 33, and the tray 31 has a central through hole 34. Furthermore, the tray 31 is provided with at least one latching protrusion 32. When the gear power device 8 meshes with the gear disk 6, the latching protrusion 32 engages with the pull-out disk 5, thereby effectively fixing the pull-out disk 5 to the pull-out positioning component 3 and preventing the pull-out disk 5 from unplanned detachment from the pull-out positioning component 3. Forceful outward pulling can cause the latching protrusion 32 to undergo elastic deformation, thereby separating the latching protrusion 32 from the pull-out disk 5. When the latching protrusion 32 engages with the pull-out disk 5, the central through hole 34 and the light-transmitting hole 54 are coaxial, allowing light to sequentially pass through the central through hole 34 and the light-transmitting hole 54 into the gear disk 6 and the projection disk 7.

[0047] In this specific embodiment, the two baffles 33 are symmetrically arranged on both sides of the tray 31, and the two baffles 33 are located on both sides of the insertion and removal direction of the pull-out tray 5, thereby restricting the degree of freedom of movement of the pull-out tray 5 and ensuring that when the pull-out tray 5 is inserted, the pull-out tray 5 moves in a straight line toward the gear power device 8.

[0048] like Figure 5 As shown, the gear disk 6 has a central hole for light to pass through; the outer wall of the gear disk 6 is surrounded by multiple toothed protrusions, so that the gear disk 6 can mesh with the output wheel of the gear power device 8 to realize transmission.

[0049] like Figure 5 As shown, the projection disk 7 includes a projection disk shell 71, which is fitted inside the gear disk 6. When the gear power device 8 drives the gear disk 6 to rotate axially, it will drive the projection disk shell 71 to rotate synchronously. Furthermore, a projection film 72 is sandwiched inside the projection disk shell 71, and light-transmitting holes 73 are opened on both the upper and lower sides of the projection disk shell 71. The two light-transmitting holes 73 and the projection film 72 are coaxial, so that light can pass through the light-transmitting holes 73 and project the image on the projection film 72 onto a flat surface such as a wall, screen, or ceiling.

[0050] Combination Figure 5 and 6 The projection disk housing 71 has a notch 715 on its edge, and the gear disk 6 has a protrusion 61 on its inner edge. When the projection disk 7 is placed inside the gear disk 6, the notch 715 and the protrusion 61 fit together, which can prevent the projection disk 7 and the gear disk 6 from rotating relative to each other. Thus, when the gear power device 8 drives the gear disk 6 to rotate axially, the projection disk 7 and the gear disk 6 rotate synchronously, achieving the effect of dynamic projection.

[0051] In this specific embodiment, there are three notches 715 and three protrusions 61, which are distributed in a ring at equal intervals. It can be understood that the number of notches 715 and protrusions 61 may be more or less.

[0052] like Figure 6 As shown, the projection disc housing 71 includes an upper housing 711 and a lower housing 712. The bottom surface of the upper housing 711 is provided with a pin 713, and the lower housing 712 is provided with a pin hole 714. When the pin 713 is inserted into the pin hole 714, the upper housing 711 and the lower housing 712 cooperate to form a cavity for accommodating and fixing the projection film 72.

[0053] In this specific embodiment, there are two of each of the pins 713 and pin holes 714, which are symmetrically arranged on both sides of the projection disc housing 71, making the upper housing 711 and the lower housing 712 more stable after they are attached. Furthermore, by prying open the cavity, the upper housing 711 and the lower housing 712 can be separated, allowing for the replacement of different projection films 72.

[0054] In this specific embodiment, the two light-transmitting openings 73 are respectively located in the center of the upper shell 711 and the lower shell 712.

[0055] like Figure 1 and Figure 2 As shown, this embodiment also includes a lamp housing 9. The pull-out positioning component 3, imaging lens module 1, illumination lens module 2, light source 4, and gear power device 8 are all disposed inside the lamp housing 9. Furthermore, a socket 91 is provided on one side of the lamp housing 9. The socket 91 is connected to the pull-out positioning component 3, so that the pull-out plate 5 is inserted into the pull-out positioning component 3 through the socket 91 until the gear plate 6 meshes with the output wheel of the gear power device 8. At this time, the light source 4, illumination lens module 2, central through hole 34 of pull-out positioning component 3, light-transmitting hole 54 of pull-out plate 5, central hole of gear plate 6, light-transmitting opening 73 of lower shell 712, projection film 72, light-transmitting opening 73 of upper shell 711, and imaging lens module 1 are all coaxial, so that the image printed on the projection film 72 can be projected onto a flat surface such as a wall, screen, or ceiling.

[0056] Working principle:

[0057] In use, hold the pull handle 53 and insert the pull plate 5 into the pull positioning piece 3 through the insertion port 91 until the latch 32 locks the bottom surface of the pull plate 5. At this time, the light emitted by the light source 4 can pass through the illumination lens module 2, the central through hole 34 of the pull positioning piece 3, the light-transmitting hole 54 of the pull plate 5, the central hole of the gear plate 6, the light-transmitting opening 73 of the lower shell 712, the projection film 72, the light-transmitting opening 73 of the upper shell 711, and the imaging lens module 1 in sequence, and finally project the image on the projection film 72 onto a flat surface such as a wall, screen or ceiling. At this time, the gear plate 6 meshes with the transmission gear 82 or the driven wheel 822, and starts the drive motor 81. The power provided by the drive motor 81 will be transmitted to the gear plate 6 through the transmission gear 82 or in sequence through the driving wheel 821 and the driven wheel 822, driving the gear plate 6 to rotate axially in the pull plate groove 51, and drive the projection plate 7 to rotate synchronously through the recess 715 and the protrusion 61, so as to achieve the effect of dynamic projection.

[0058] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
