Detailed Implementation

[0028] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort are within the scope of protection of the present application.

[0029] Please see Figure 1 This application provides a projector module 100, a projector holder 400 configured with the projector module 100, and a projection device 1000 configured with the projector holder 400. In this embodiment, the projection device 1000 is a device for projecting light onto a projection object to produce light effects or form images. As an example, the projection device 1000 can project light onto a screen to form pictures or text on the screen; as another example, the projection device 1000 can project light onto a wall to form light effects such as water ripples or starry sky-like light spots.

[0030] In this embodiment, the projection device 1000 may include a housing 900, a projection lens 700, and a light source module 800. The housing 900 generally defines the external structure of the projection device 1000. The housing 900 is hollow inside to accommodate other components, such as the light source module 800, which is disposed inside the housing 900. The light source module 800 is used to emit light or laser light. Placing the light source module 800 inside the housing 900 reduces light divergence loss and avoids light leakage problems in the projection device 1000. In this embodiment, the light source module 800 may include light-emitting structures such as LED beads and laser lights. In this embodiment, the projection lens 700 is mounted on the housing 900 and is located in the optical path of the light source module 800. The light from the light source module 800 can be transmitted through the projection lens 700 to the outside of the housing 900.

[0031] Please see Figure 1 and Figure 2 In this embodiment, a projection sheet assembly 10 is provided between the projection lens 700 and the light source module 800. Light from the light source module 800 passes through the projection sheet assembly 10 and the projection lens 700 in sequence. In this embodiment, the projection sheet assembly 10 displays an image, which may include people, landscapes, text, patterns, etc. After passing through the projection sheet assembly 10, the light is projected onto the object to form an image. In other embodiments, a light effect forming layer may be provided on the surface of the projection sheet assembly 10, including water ripples, star patterns, etc. In this embodiment, the projection sheet assembly 10 may include a film 11 and two protective layers 12, which cover opposite sides of the film 11 to protect it. In this embodiment, the protective layer 12 is a transparent structure, such as glass or acrylic sheet. In other embodiments, other optical elements may be provided in the optical path between the projection lens 700 and the light source module 800, such as convex (concave) lenses, filters, gratings, and reflectors (prisms).

[0032] Please see Figure 1 and Figure 3 In this embodiment, the projection sheet assembly 10 is mounted on the projection device 1000 via a projection sheet holder 400 and is located between the light source module 800 and the projection lens 700. Specifically, the projection sheet holder 400 includes a mounting bracket 300, to which the projection sheet assembly 10 is connected. The housing 900 is provided with a mounting channel 910 communicating with its interior and exterior. The mounting bracket 300 uses the mounting channel 910 to mount the projection sheet assembly 10 into the housing 900 or to remove the projection sheet from the housing 900. When the mounting bracket 300 is mounted on the housing 900, the mounting bracket 300 passes through the mounting channel 910 and extends into the interior of the housing 900. The projection sheet assembly 10 is connected to the mounting bracket 300 and is located in the optical path of the light source module 800.

[0033] In this embodiment, the slide holder 400 further includes a connector 200, which is connected to the mounting bracket 300. The slide assembly 10 is connected to the connector 200, and both opposite sides of the slide assembly 10 are exposed through the connector 200, allowing light to pass through the slide assembly 10 and be transmitted to the projection lens 700. In this embodiment, the connector 200 is rotatably mounted on the mounting bracket 300, and the slide assembly 10 rotates with the connector 200, so that the projection device 1000 can create dynamic light effects on the projected object, such as continuously displaying multiple images to create a carousel effect or a slideshow effect, or creating a continuously moving starry sky effect, making the projection effect of the projection device 1000 more vivid and interesting.

[0034] In this embodiment, the projection device 1000 further includes a driving component (not shown in the figure), which is disposed inside the housing 900 and is connected to the connector 200 for transmission. In this embodiment, the driving component may include a motor, which may be directly connected to the connector 200 to drive the connector 200, or indirectly driven by a transmission structure such as a transmission belt, gear, or rack. The outer periphery of the connector 200 may be provided with teeth or other structures to cooperate with the transmission structure. In some other embodiments, the connector 200 and the mounting bracket 300 may be in a relatively stationary state. In some other embodiments, the projection sheet assembly 10 may be directly mounted on the mounting bracket 300.

[0035] In this embodiment, the projection device 1000 may include multiple projection sheet assemblies 10, each of which forms a different image after being illuminated by light from the light source module 800. In this embodiment, each projection sheet assembly 10 is combined with other structures to form a projection sheet module 100. Therefore, the projection device 1000 in this embodiment includes multiple projection sheet modules 100, each of which is a single integral structure. The projection sheet module 100 is detachably connected to the connector 200, and the corresponding projection sheet module 100 can be selected according to projection requirements. In this embodiment, replacing individual projection sheet modules 100 achieves the replacement of individual projection sheet assemblies 10, making the replacement of projection sheet modules 100 simple and convenient, facilitating user operation, and improving the user experience of the projection device 1000.

[0036] Please see Figure 3 , Figure 4 and Figure 5 In this embodiment, the projection panel module 100 includes a projection panel assembly 10 and a mounting member 20. The mounting member 20 includes a mounting portion 21, and the projection panel assembly 10 is mounted on the mounting portion 21 and forms an integral structure with the mounting portion 21. Specifically, the mounting portion 21 is provided with a light-transmitting hole 213, and the projection panel assembly 10 is mounted in the light-transmitting hole 213. The light-transmitting hole 213 has two ports 2131 in its axial direction, and the opposite sides of the projection panel assembly 10 are exposed through the two ports 2131, so that light can pass through the projection panel assembly 10 and be conducted to the projection lens 700. In this embodiment, the mounting member 20 may also include at least one connecting portion 22, which is connected to the mounting portion 21.

[0037] Please see Figure 5 , Figure 6 and Figure 7In this embodiment, the connector 200 is provided with at least one mating part 230, and each connector 22 has a corresponding mating part 230. The connector 22 and the mating part 230 are detachably connected to realize the connection between the projector module 100 and the connector 200, thereby realizing the detachable connection between the projector module 100 and the mounting bracket 300 of the projector holder 400. In this embodiment, the process of assembling the projector assembly 10 and the mounting part 20 can be completed during the production process. Users do not need to assemble the projector assembly 10 and the mounting part 20 themselves, reducing the number of operation steps when using the projection device 1000. Users can replace the projector assembly 10 by disassembling and assembling the projector module 100, which is simple to operate.

[0038] In summary, this application provides a projection panel module 100, which includes a projection panel assembly 10 and a mounting component 20. The mounting component 20 includes a mounting portion 21 and a connecting portion 22 connected to each other. The mounting portion 21 has a light-transmitting hole 213, in which the projection panel assembly 10 is installed. The opposite sides of the projection panel assembly 10 are exposed through the light-transmitting hole 213. The connecting portion 22 is detachably connected to the connecting component 200 of the projection panel bracket 400, so that the projection panel module 100 can be detachably installed on the mounting bracket 300. In this embodiment, the separate projection panel assembly 10 and the mounting component 20 are integrated into a single integral structure. The user can replace the projection panel assembly 10 by disassembling and assembling the mounting component 20 and the mounting bracket 300, which reduces the number of steps required to replace the projection panel assembly 10, simplifies the use of the projection device 1000, and improves the user experience.

[0039] Please see Figure 4 , Figure 6 and Figure 7 In this embodiment, the mounting component 20 has a cylindrical or frame-like structure. The mounting component 20 defines a light-transmitting hole 213 through its own structure, resulting in high structural utilization and a small volume, facilitating the cooperation between the projection module 100 and the connector 200, mounting bracket 300, and other structures. Please refer to... Figure 5 In this embodiment, the connecting portion 22 is disposed on the outer periphery of the mounting member 20, so that the connecting portion 22 avoids the port 2131 of the light-transmitting hole 213, preventing the connecting portion 22 from being located in the light path and from appearing in the image or light effect formed by the projection device 1000, thereby improving the projection effect of the projection device 1000. In this embodiment, multiple connecting portions 22 are provided, and the multiple connecting portions 22 are arranged sequentially at intervals along the circumference of the mounting portion 21.

[0040] In this embodiment, the connector 200 is provided with a plurality of mating portions 230, which are arranged around the outer periphery of the slide module 100. A plurality of connecting portions 22 correspond one-to-one with the plurality of mating portions 230, and each connecting portion 22 is detachably connected to its corresponding mating portion 230. In this embodiment, the plurality of connecting portions 22 are arranged around the outer periphery of the mounting portion 21, allowing the slide module 100 to connect to the connector 200 at multiple positions in its circumferential direction, thus making the connection between the mounting portion 20 and the connector 200 relatively stable.

[0041] In this embodiment, the connector 200 is provided with a mounting groove 210 and a light-emitting hole 220. The mounting groove 210 and the light-emitting hole 220 are connected, and the opening of the mounting groove 210 and the light-emitting hole 220 are located on opposite sides of the mounting groove 210. In this embodiment, the mounting groove 210 has an abutment wall 240, which is located on the bottom wall of the mounting groove 210 and faces the opening of the mounting groove 210. The light-emitting hole 220 passes through the abutment wall 240. When at least a part of the structure of the projection panel module 100 is embedded in the mounting groove 210, the abutment wall 240 abuts against the mounting member 20 to limit the projection panel module 100 within the mounting groove 210. In this embodiment, the light-emitting hole 220 is connected to the light-transmitting hole 213, so that the opposite sides of the projection panel assembly 10 are exposed. In this embodiment, the inner sidewall of the mounting groove 210 is provided with a plurality of mating parts 230, and each mating part 230 is detachably connected to a corresponding connecting part 22.

[0042] In this embodiment, the detachable connection between the connecting part 22 and the mating part 230 can be in various ways. As an example, such as... Figure 5 and Figure 7 As shown, the connecting portion 22 includes a connecting block, and the mating portion 230 has a groove-like structure, with the connecting portion 22 detachably embedded in the mating portion 230. As another example, the connecting portion 22 includes a connecting slot, and the mating portion 230 has a protrusion-like structure, with the mating portion 230 detachably embedded in the connecting portion 22. As yet another example, the connecting portion 22 includes a connecting magnet, and the mating portion 230 may include a magnetic structure or a metal structure, with the connecting portion 22 and the mating portion 230 magnetically connected.

[0043] It should be noted that the embodiments of this application do not limit the specific shape of the mounting part 20, the number of connecting parts 22, the position and distribution of the connecting parts 22 on the mounting part 21, the detachable connection method between the connecting parts 22 and the mating part 230, etc. In other embodiments, the above features can be implemented in other ways as long as they can meet the requirements of exposing the projection sheet assembly 10, detachable connecting mounting part 20 and connecting part 200.

[0044] Please see Figure 6 , Figure 8 and Figure 9In this embodiment, the mounting part 21 has two opposing end faces (not shown in the figure), which are approximately located at the two ends of the light-transmitting through hole 213 along the axial direction. The outer periphery of the mounting part 21 is located between the two end faces. To facilitate the distinction between the two end faces, this embodiment defines the two end faces as a front face 2141 and a back face 2142, respectively. In one case where the slide module 100 is mounted in the mounting groove 210, the front face 2141 of the mounting part 21 faces the abutment wall 240, and the front face 2141 is opposite to and in contact with the abutment wall 240 (referring to abutment, fit, etc.). In this embodiment, the back face 2142 of the mounting part 21 can also contact the abutment wall 240. The slide module 100 is rotated 180° so that the back face 2142 faces the abutment wall 240, and then the slide module 100 is installed into the mounting groove 210. When the assembly is complete, the back face 2142 of the mounting part 21 contacts the abutment wall 240.

[0045] It should be noted that, in this embodiment, the end face can be a surface with a large area on the mounting part 21. For example, the front surface 2141 of the mounting part 21 is one side surface of the mounting part 21, and the light-transmitting hole 213 passes through the front surface 2141. In this embodiment, the end face can be a plane defined by a part of the structure of the mounting part 21. For example, the side of the mounting part 21 away from the front surface 2141 has multiple protruding structures (such as protrusions, ribs, etc.). When the mounting part 21 is installed in the mounting groove 210 and the front surface 2141 is located on the mounting part 21 away from the abutment wall 240, the multiple protruding structures respectively make point contact, line contact, or planar contact (small contact area) with the abutment wall 240. Then, the plane defined by the multiple points, multiple lines, or multiple small planes on the mounting part 21 that contact the abutment wall 240 is the end face, that is, the back surface 2142 of the mounting part 21. In some cases, the portion of the protruding structure on the side of the mounting portion 21 away from the front face 2141 does not contact the abutment wall 240. For example, this portion of the protruding structure extends into or out of the light transmission hole 220, or is spaced apart from the abutment wall 240. Such protruding structures do not participate in defining the end face (back face 2142) of the mounting portion 21.

[0046] Please see Figure 8 and Figure 9In this embodiment, the connecting portion 22 is disposed on the outer periphery of the mounting portion 21. The distance between the connecting portion 22 and the two end faces is the same. When the front side 2141 of the mounting portion 21 contacts the abutment wall 240, the connecting portion 22 can be detachably connected to the mating portion 230. When the back side 2142 of the mounting portion 21 contacts the abutment wall 240, the connecting portion 22 can still be detachably connected to the mating portion 230. In this embodiment, the connecting portion 22 has a certain size, and the distance between the connecting portion 22 and the end face can be selected as the distance between the structural center point of the connecting portion 22 and the end face. In this embodiment, when the content recorded on the slide assembly 10 is projected without needing to distinguish between the front and back, the user does not need to distinguish between the front and back of the slide module 100 when installing or replacing the slide module 100, which is convenient for the user. In some other embodiments, if it is necessary to distinguish between the front and back when the content recorded on the slide assembly 10 is projected, the distance between the connecting part 22 and the two end faces can be set differently; or it can be set the same, so that if the slide module 100 is installed backwards, it can be corrected or compensated by other optical elements (reflectors, etc.).

[0047] In embodiments where the distance between the connecting portion 22 and the two end faces is the same, the connecting portion 22 can be detachably fitted and connected to the mating portion 230. For example, one of the connecting portion 22 and the mating portion 230 may be a connecting block, and the other may be a connecting slot; or one of the connecting portion 22 and the mating portion 230 may be a pin structure, and the other may be a pin hole. In some embodiments, the connecting portion 22 can be magnetically connected to the mating portion 230. For example, the connecting portion 22 may include a connecting magnet, and the mating portion 230 may include a magnetic structure or a metal structure, and the connecting portion 22 and the mating portion 230 are magnetically connected; or the connecting portion 22 may include a magnetic structure or a metal structure, and the mating portion 230 may include a connecting magnet, and the connecting portion 22 and the mating portion 230 are magnetically connected.

[0048] Please see Figure 10In this embodiment, the mounting member 20 further includes at least one elastic limiting part 23, which is connected to the mounting part 21. At least a portion of the structure of the elastic limiting part 23 is located at one port 2131 of the light-transmitting hole 213, thereby partially covering the port 2131 of the light-transmitting hole 213. The elastic limiting part 23 can restrict the projection sheet assembly 10 from detaching from the light-transmitting hole 213. In this embodiment, the elastic limiting part 23 is an elastically deformable structure. Under the action of external force, the projection sheet assembly 10 is pressed against the elastic limiting part 23, causing the elastic limiting part 23 to bend and move away from the port 2131 of the light-transmitting hole 213, so that the port 2131 of the light-transmitting hole 213 is substantially completely exposed, so as to facilitate the installation of the projection sheet assembly 10. In this embodiment, the elastic limiting part 23 allows the mounting part 20 to be detachably connected to the slide assembly 10. Users can separate the mounting part 20 from the slide assembly 10 to replace different slide assemblies 10, or replace aged or damaged slide assemblies 10. The mounting part 20 can be recycled, which is environmentally friendly and economical, and reduces the user's operating costs.

[0049] In this embodiment, the mounting portion 21 includes a support portion 211, which is located at one end of the light-transmitting hole 213. The light-transmitting hole 213 passes through the support portion 211, and portions of the support portion 211 and the elastic limiting portion 23 are located at opposite ends of the light-transmitting hole 213. In a practical application scenario, the projection sheet assembly 10 is mounted on the light-transmitting hole 213 and abuts against the support portion 211. At least a portion of the elastic limiting portion 23 is located at the end of the light-transmitting hole 213 away from the support portion 211, thereby partially covering the port 2131 of the light-transmitting hole 213. This portion of the elastic limiting portion 23 is located on the side of the projection sheet assembly 10 opposite to the support portion 211. In this embodiment, the slide assembly 10 is located between the support portion 211 and the elastic limiting portion 23 to limit the scattered slide assembly 10 within the light-transmitting hole 213, thereby integrating the mounting member 20 and the slide assembly 10 into a single independent slide module 100, so as to facilitate the user to disassemble or replace the slide module 100.

[0050] In this embodiment, the mounting part 21 further includes a retaining part 212, which is connected to one side of the supporting part 211. The retaining part 212 is arranged around at least a portion of the outer periphery of the supporting part 211, and the supporting part 211 and the retaining part 212 together define a light-transmitting hole 213. It should be noted that the light-transmitting hole 213 referred to in this embodiment is a through hole with two ports 2131 that can transmit light. The light-transmitting hole 213 may have multiple segments with different radii in its axial direction, and the shape of each segment is not limited to a circle, but may also be a quadrilateral, a polygon, etc. In this embodiment, the outline of the inner wall of the enclosure 212 facing the light-transmitting hole 213 is approximately the same as the peripheral outline of the projection sheet assembly 10. When the projection sheet assembly 10 is installed in the light-transmitting hole 213, the peripheral edge of the projection sheet assembly 10 contacts the inner peripheral side of the enclosure 212 to limit the projection sheet assembly 10 from shaking significantly within the light-transmitting hole 213 and prevent the projection sheet assembly 10 from moving and affecting the projection effect.

[0051] In this embodiment, both the blocking portion 212 and the elastic limiting portion 23 are connected to the supporting portion 211. The blocking portion 212 and the elastic limiting portion 23 are connected to the outer periphery of the supporting portion 211 at intervals. Part of the structure of the elastic limiting portion 23 is movable relative to the supporting portion 211 and the blocking portion 212. In this embodiment, the connecting portion 22 is disposed on the side of the blocking portion 212 opposite to the light-transmitting hole 213. Referring to the above, the blocking portion 212 is located between the two end faces of the mounting portion 21, and the side of the blocking portion 212 (and the elastic limiting portion 23) opposite to the light-transmitting hole 213 defines the outer periphery of the mounting portion 21. In this embodiment, the blocking portion 212 includes a plurality of surrounding plates 2121, which are sequentially and at intervals connected to the outer periphery of the supporting portion 211. The plurality of surrounding plates 2121 are arranged around the outer periphery of the projection sheet assembly 10 to better restrict the movement of the projection sheet assembly 10. In this embodiment, at least one enclosure 2121 has a connecting portion 22 on the side opposite to the light-transmitting hole 213. In some other embodiments, an elastic limiting portion 23 may be connected to the enclosure portion 212, and at least a portion of the structure of the elastic limiting portion 23 is bent relative to the enclosure portion 212 and located on the side of the projection panel assembly 10 opposite to the support portion 211.

[0052] In this embodiment, the protrusion height of the elastic limiting part 23 relative to the supporting part 211 is greater than the protrusion height of the blocking part 212 relative to the supporting part 211. The elastic limiting part 23 is the plurality of protruding structures on the side of the mounting part 21 away from the front face 2141 mentioned above. The elastic limiting part 23 defines the back face 2142 of the mounting part 21. When the slide module 100 is mounted in the mounting groove 210 and the back face 2142 is in contact with the abutment wall 240, the elastic limiting part 23 abuts against the abutment wall. In some other embodiments, the protrusion height of the elastic limiting part 23 relative to the supporting part 211 is the same as the protrusion height of the blocking part 212 relative to the supporting part 211. In this case, the elastic limiting part 23 and the blocking part 212 together define the back face 2142 of the mounting part 21.

[0053] Please see Figure 10 In this embodiment, there are multiple elastic limiting parts 23, each located between two adjacent surrounding plates 2121. These multiple elastic limiting parts 23 are arranged around the outer periphery of the projection sheet assembly 10 to effectively confine the projection sheet assembly 10 within the light-transmitting hole 213, thus making the structure of the projection sheet module 100 more stable. In this embodiment, the number of elastic limiting parts 23 is the same as the number of surrounding plates 2121, and the multiple elastic limiting parts 23 and the multiple surrounding plates 2121 are arranged alternately. In some other embodiments, two or more elastic limiting parts 23 can be provided between two adjacent surrounding plates 2121 to improve the structural stability of the projection sheet module 100. In some other embodiments, the number of elastic limiting parts 23 can be reduced according to actual limiting requirements, resulting in a situation where no elastic limiting parts 23 are provided between two adjacent surrounding plates 2121.

[0054] In this embodiment, each elastic limiting portion 23 includes an elastic portion 231 and a blocking portion 232. The elastic portion 231 is connected to the support portion 211 and protrudes relative to the support portion 211. The blocking portion 232 is connected to the side of the elastic portion 231 away from the support portion 211. The blocking portion 232 and the support portion 211 are spaced apart from each other. The slide assembly 10 is located between the blocking portion 232 and the support portion 211 to be stably installed on the mounting member 20. In this embodiment, the elastic portion 231 is made of a non-elastic material and has an elongated or flat structure to be elastic. In some other embodiments, the elastic portion 231 may be a structure made of an elastic material to be elastic. In this embodiment, there are a large number of elastic limiting portions 23. The blocking portion 232 of the elastic limiting portion 23 has a protruding structure, and multiple blocking portions 232 are arranged sequentially and spaced apart along the periphery of the slide assembly 10. In some other embodiments, the number of elastic limiting portions 23 is small, such as one or two. In such embodiments, the size of the blocking portion 232 can be set to be large. The blocking portion 232 may include a baffle extending along the periphery of the slide assembly 10 so that the blocking portion 232 can effectively restrict the slide assembly 10 from exiting the light-transmitting through-hole 213.

[0055] This application provides a projection panel module 100, which includes a projection panel assembly 10 and a mounting component 20. The mounting component 20 includes a mounting portion 21 and a connecting portion 22 connected to each other. The mounting portion 21 has a light-transmitting hole 213, in which the projection panel assembly 10 is installed. The opposite sides of the projection panel assembly 10 are exposed through the light-transmitting hole 213. The connecting portion 22 is detachably connected to the connecting component 200 of the projection panel bracket 400, so that the projection panel module 100 can be detachably installed on the mounting bracket 300. In this embodiment, the separate projection panel assembly 10 and the mounting component 20 are integrated into a single integral structure. The user can replace the projection panel assembly 10 by disassembling and assembling the mounting component 20 and the mounting bracket 300, which reduces the number of steps required to replace the projection panel assembly 10, simplifies the use of the projection device 1000, and improves the user experience.
