[0042] The following is an introduction to the embodiments of the present application in conjunction with the accompanying drawings:

[0043] refer to Figure 1 and Figure 2 According to the first embodiment of the present application, the film box 100 comprises a box body 110 and a cover body 120, the cover body 120 and the box body 110 are connected, a positioning groove 111 is provided on the box body 110, a first opening 112 is provided on the bottom wall in the positioning groove 111, the positioning groove 111 is used to accommodate a light-transmitting film 130, and the bottom wall of the positioning groove 111 is used to support the edge of the light-transmitting film 130, so as to accommodate the light-transmitting film 130 in the positioning groove 111. It should be noted that a pattern for projection is provided on the light-transmitting film 130, and the edge of the light-transmitting film 130 is a pattern-free area. The edge of the first opening 112 supports the edge of the light-transmitting film 130, which can avoid the pattern on the light-transmitting film 130, avoid the bottom wall of the positioning groove 111 from blocking the pattern on the light-transmitting film 130, ensure the integrity of the projected image, and help improve the projection display effect.

[0044] The cover 120 is provided with a second opening 121 and a positioning protrusion 122. The positioning protrusion 122 is located at the outer peripheral side of the second opening 121, and the positioning protrusion 122 protrudes outward from the inner wall of the cover 120. The film box 100 has a fixed state and a released state. In the fixed state, the cover 120 fits the box body 110, and at least part of the positioning protrusion 122 is located in the positioning groove 111, which is used to abut the light-transmitting film 130 at the outer peripheral side of the first opening 112, so that the light-transmitting film 130 is fixed in the positioning groove 111. The positioning protrusion 122 can prevent the light-transmitting film 130 from wrinkling or moving, which is beneficial to ensure the clarity and integrity of the projected pattern, so as to improve the light and shadow effect. In the released state, the box body 110 and the cover body 120 are separated from each other, and the positioning protrusion 122 loses the abutting relationship with the light-transmitting film 130, so that the light-transmitting film 130 in the positioning groove 111 can be replaced. Different types of light-transmitting films 130 have different patterns. By replacing the light-transmitting film 130 and then adjusting the film box 100 to a fixed state and inserting it into the projector 200, a variety of light and shadow effects can be projected, which is beneficial to meet different photography needs.

[0045] Specifically, when in a fixed state, the position of the positioning protrusion 122 corresponds to the outer peripheral side of the first opening 112 in the positioning groove 111, and the light-transmitting film 130 is located between the positioning protrusion 122 and the positioning groove 111. The positioning protrusion 122 supports the light-transmitting film 130 from one side of the light-transmitting film 130, and the bottom wall of the positioning groove 111 located on the outer peripheral side of the first opening 112 supports the light-transmitting film 130 from the other side of the light-transmitting film 130. The positioning protrusion 122 and the edge of the first opening 112 jointly support the light-transmitting film 130, which is beneficial to more stably fix the light-transmitting film 130, prevent the light-transmitting film 130 from moving relative to the box body 110 during the projection process and generating wrinkles, resulting in changes in the projection pattern, and is beneficial to ensuring the projection effect.

[0046] In some embodiments, the positioning protrusion 122 includes a plurality of positioning posts, and the second opening 121 includes four peripheral walls, and two positioning posts are provided on each side of each peripheral wall. In a fixed state, the eight positioning posts are at least partially located in the positioning groove 111. The light-transmitting film 130 can be fixed in the positioning groove 111 through the eight positioning posts, which is beneficial to prevent the light-transmitting film 130 from moving in the positioning groove 111 and ensure the flatness of the light-transmitting film 130.

[0047] In other embodiments, the positioning protrusion 122 includes a plurality of positioning posts, and the second opening 121 includes four peripheral walls, each peripheral wall having a positioning post on its side. In a fixed state, the four positioning posts are at least partially located in the positioning groove 111, and the four positioning posts can support the edges of the light-transmitting film 130 to fix the light-transmitting film 130.

[0048] In other embodiments, the positioning protrusion 122 includes a plurality of positioning posts, the second opening 121 includes four peripheral walls, and along the axial direction of the rotation axis, two positioning posts are respectively provided at two opposite peripheral walls of the first opening 112. In a fixed state, the four positioning posts are at least partially located in the positioning groove 111, and the four positioning posts can support the edges of the light-transmitting film 130 to fix the light-transmitting film 130.

[0049] In other embodiments, the positioning protrusion 122 includes a plurality of positioning posts, the second opening 121 includes four peripheral walls, and two positioning posts are respectively provided at two opposite peripheral walls of the first opening 112 along a direction perpendicular to the axial direction of the rotation axis. In a fixed state, the four positioning posts are at least partially located in the positioning groove 111, and the four positioning posts can support the edges of the light-transmitting film 130 to fix the light-transmitting film 130.

[0050] In other embodiments, the positioning protrusion 122 includes a plurality of positioning posts, and the second opening 121 includes four peripheral walls. Along the axial direction of the rotating shaft, a positioning post is provided at each of the two opposite peripheral walls of the first opening 112. Along the direction perpendicular to the axial direction of the rotating shaft, two positioning posts are provided at each of the two opposite peripheral walls of the first opening 112. In a fixed state, the six positioning posts are at least partially located in the positioning groove 111, and the six positioning posts can support the edges of the light-transmitting film 130 to fix the light-transmitting film 130.

[0051] It should be noted that other numbers of positioning posts may be provided on the outer peripheral wall of the second opening 121 , and the numbers of positioning posts on different sides may be different.

[0052] refer to Figures 1 to 3 In some embodiments, a connection structure 123 is provided on the cover 120, and the cover 120 is rotatably connected to the box body 110 through the connection structure 123. Compared with the snap connection between the cover 120 and the box body 110, the buckle needs to be deformed and easily cracked during the snap connection. The rotation connection allows the cover 120 to rotate relative to the box body 110 around a rotation axis, and there is no need to disassemble the buckle when switching between the fixed state and the released state. A limiting wall 1231 is provided on the connection structure 123. In the released state, the limiting wall 1231 can abut the box body 110, thereby limiting the opening angle of the cover 120 relative to the box body 110. Compared with no limiting wall 1231, limiting the opening angle of the cover 120 relative to the box body 110 helps to reduce the opening and closing angle of the cover 120 and the box body 110 when replacing the light-transmitting film 130, thereby reducing the wear of the cover 120 and the box body 110 at the connection, which is beneficial to prolonging the service life of the film box 100.

[0053] refer to Figure 2 In some embodiments, a first magnetic portion 113 is further provided on the box body 110, and the first magnetic portion 113 is located on the side of the positioning groove 111 away from the connecting structure 123. A second magnetic portion 124 is provided on the cover body 120. When in a fixed state, the first magnetic portion 113 can absorb the second magnetic portion 124, and the box body 110 and the cover body 120 fit together. Compared with the snap-fit ​​method, it is convenient to open and close the film box 100, which is beneficial to extend the service life of the film box 100.

[0054] Specifically, the first magnetic attraction portion 113 can be a magnet, and the second magnetic attraction portion 124 can be a metal column that is easily attracted by the magnet, or the second magnetic attraction portion 124 can be a magnet and the first magnetic attraction portion 113 can be a metal column that is easily attracted by the magnet, or the first magnetic attraction portion 113 is a magnet and the second magnetic attraction portion 124 can be a magnet with opposite polarity to the first magnetic attraction portion 113, and the two can attract each other, and the positioning groove 111 is located between the connecting structure 123 and the magnetic attraction portion 113. One side of the box body 110 and the cover body 120 is connected by the connecting structure 123, and the other side is connected by the mutual attraction between the first magnetic attraction portion 113 and the second magnetic attraction portion 124. Through the magnetic connection, it is convenient for the film box 100 to switch between the fixed state and the released state, which is beneficial to extend the service life of the film box 100.

[0055] refer to Figures 2 to 4 In some embodiments, the connection structure 123 includes a limiting portion 125, a first connecting portion 126 and a second connecting portion 127. The limiting portion 125 is provided with a limiting wall 1231. The first connecting portion 126 is rotatably connected to the box body 110, and the second connecting portion 127 is also rotatably connected to the box body 110. Along the axial direction of the rotation axis, a first interval 1261 is provided between the first connecting portion 126 and the limiting portion 125, and a second interval 1271 is provided between the second connecting portion 127 and the limiting portion 125. The first interval 1261 is used to provide a deformation space for the first connecting portion 126, and the second interval 127 1 is used to provide deformation space for the second connection part 127. When switching between the fixed state and the released state, the cover body 120 rotates relative to the box body 110 around a rotation axis. Along the axial direction of the rotation axis, the first interval 1261 can provide a buffer space for the elastic deformation of the first connection part 126, and the second interval 1271 can provide a buffer space for the elastic deformation of the second connection part 127. Compared with the rigid connection, the first interval 1261 and the second interval 1271 can provide a buffer along the axial direction of the rotation axis when the cover body 120 and the box body 110 rotate, thereby reducing the impact on the connection structure 123. It is beneficial to extend the service life of the movie box 100.

[0056] refer to Figures 2 to 4 In some embodiments, the positioning groove 111 includes at least two groove walls 1111 arranged opposite to each other, each groove wall 1111 is perpendicular to the bottom wall of the positioning groove 111, and the positioning groove 111 is used to accommodate the light-transmitting film 130. The light-transmitting film 130 is placed in the positioning groove 111. Each groove wall 1111 of the positioning groove 111 abuts against the side edge of the light-transmitting film 130 corresponding to the groove wall 1111, thereby limiting the movement of the light-transmitting film 130 in the positioning groove 111. Each groove wall 1111 can form a good positioning for the light-transmitting film 130. On the basis of setting the positioning protrusion 122, the assembly accuracy of the light-transmitting film 130 can be further improved.

[0057] Specifically, the light-transmitting film 130 can be a rectangle, and the positioning groove 111 can also be set to a rectangle accordingly. The size of the light-transmitting film 130 is the same as the size of the positioning groove 111. A first opening 112 is opened on the bottom wall of the positioning groove 111. The bottom wall of the positioning groove 111 is used to carry the light-transmitting film 130. In addition to the bottom wall of the positioning groove 111, the positioning groove 111 also includes four groove walls 1111, and each groove wall 1111 is perpendicular to the bottom wall of the positioning groove 111. Each groove wall 1111 can correspond to a side edge of the light-transmitting film 130. Each groove wall 1111 can maintain a good fit with the side edge of the light-transmitting film 130 to limit the movement of the light-transmitting film 130 in the positioning groove 111, so that the position where the pattern is provided on the light-transmitting film 130 can correspond to the center of the first opening 112, which is beneficial to improving the projection effect.

[0058] refer to Figure 4 In some embodiments, along the axial direction of the rotation axis, the positioning groove 111 is provided with two opposite groove walls 1111, and the two groove walls 1111 are perpendicular to the bottom wall of the positioning groove 111. The light-transmitting film 130 is placed in the positioning groove 111. Along the axial direction of the rotation axis, one of the groove walls 1111 abuts against one side wall of the light-transmitting film 130, and the other groove wall 1111 abuts against the other side wall opposite to the light-transmitting film 130, thereby fixing the light-transmitting film 130. In the fixed state, at least part of the positioning protrusion 122 is located in the positioning groove 111, and abuts against the light-transmitting film 130 on the outer peripheral side of the first opening 112, thereby further fixing the light-transmitting film 130, which is beneficial to improving the projection effect.

[0059] refer to Figures 1 to 7 In some embodiments, the cover body 120 is provided with a clamping portion 128, which protrudes from the outer wall of the cover body 120. The clamping portion 128 is suitable for clamping with the projection body 211 of the projector 200. The clamping portion 128 is provided with a first inclined wall 1281. Along the direction of inserting the film box 100 into the accommodating cavity 212, the distance between the first inclined wall 1281 and the outer wall of the cover body 120 gradually increases. The first inclined wall 1281 can provide a guide for pulling the film box 100 out of the accommodating cavity 212, ensuring that the film box 100 can be pulled out of the accommodating cavity 212. It should be understood that the clamping portion 128 can be clamped into the clamping groove 213 on the projection body 211, which helps to ensure that the film box 100 is connected to the projection body 211 in place, thereby ensuring the projection imaging effect.

[0060] It should be understood that the clamping portion 128 has elastic deformation capability, so that when the clamping portion 128 is clamped into the clamping slot 213 or detached from the clamping slot 213 , the clamping portion 128 can generate elastic deformation, which facilitates the detachable connection between the film box 100 and the projection body 211 .

[0061] refer to Figure 5According to the projector 200 of the second aspect of the present application, the projector comprises a projection assembly 210 and a film box 100 in any of the above embodiments. The projection assembly 210 comprises a projection body 211, and a receiving cavity 212 is provided on the projection body 211. The projection body 211 is used to connect a lamp. The film box 100 is detachably connected to the receiving cavity 212. A light-transmitting film 130 is fixed in the film box 100, and a pattern is provided on the light-transmitting film 130. The lamp is connected to the projection body 211 and can be used as a light source to illuminate the light-transmitting film 130 in the film box 100 to project the pattern on the light-transmitting film 130. By replacing the light-transmitting film 130 with different patterns, different light and shadow effects can be provided for photography, which is beneficial for obtaining richer pictures.

[0062] refer to Figure 6 and Figure 7 In some embodiments, a snap-in groove 213 is provided in the accommodating cavity 212, and a second inclined wall 2131 is provided in the snap-in groove 213. Along the direction in which the film box 100 is inserted into the accommodating cavity 212, the second inclined wall 2131 gradually approaches the bottom wall of the snap-in groove 213. A snap-in portion 128 is provided on the film box 100, and the snap-in portion 128 protrudes outward from the outer wall of the film box 100. A first inclined wall 1281 is provided on the snap-in portion 128. Along the direction in which the film box 100 is inserted into the accommodating cavity 212, the first inclined wall 1281 gradually moves away from the outer wall of the film box 100. The snap-in portion 128 is used to snap into the snap-in groove 213, and the second inclined wall 2131 abuts against the first inclined wall 1281. The angle between the inclined wall 1281 and the outer wall of the film box 100 can be the same as the angle between the second inclined wall 2131 and the bottom wall of the clamping groove 213, that is, the first inclined wall 1281 and the second inclined wall 2131 can have the same inclination angle. The first inclined wall 1281 and the second inclined wall 2131 can provide a guide for the film box 100 to be pulled out of the accommodating cavity 212. When the film box 100 is pulled out of the accommodating cavity 212, the clamping portion 128 can slide out of the clamping groove 213 along the inclination direction of the first inclined wall 1281, which is beneficial to ensure the detachable connection between the film box 100 and the accommodating cavity 212, and is convenient for replacing the film box 100 with a light-transmitting film 130 with different patterns.

[0063] refer to Figures 5 to 8In some embodiments, the projection assembly 210 further includes an adapter seat 214 and a first fixing member 215, the first fixing member 215 is connected to the projection body 211, an adapter portion 2141 is provided on the adapter seat 214, a first protrusion 2151 is provided on the first fixing member 215, and a second protrusion 2111 is provided on the projection body 211. Along the projection direction, the adapter portion 2141 is located between the first protrusion 2151 and the second protrusion 2111, and the first protrusion 2151 is abutted against one side of the adapter portion 2141, and the second protrusion 2111 is abutted against the other side opposite to the adapter portion 2141. The first protrusion 2151 and the second protrusion 2111 jointly abut the adapter portion 2141 to limit the separation of the adapter seat 214 from the projection body 211.

[0064] It should be noted that the first protrusion 2151 and the second protrusion 2111 jointly abut the adapter 2141, and can generate friction between the adapter 2141. The user can overcome the friction to make the adapter 214 rotate relative to the projection body 211 with the projection direction as the rotation axis, and in the absence of external force, the friction can limit the adapter 2141 and the projection body 211 from rotating with the projection direction as the rotation axis. The accommodating cavity 212 of the projection body 211 contains a film box 100, and a light-transmitting film 130 is fixed in the film box 100. A certain projection pattern is preset on the light-transmitting film 130. The adapter 214 is used to connect the lamp. Applying external force to make the adapter 2141 rotate relative to the projection body 211 can make the projection pattern rotate relative to the lamp with the projection direction as the rotation axis, which is convenient for adjusting the circumferential angle of the pattern with the projection direction as the rotation axis, and avoiding rotating the entire projector 200, which is beneficial to obtain richer projection effects.

[0065] refer to Figure 8 and Fig. 9 The adapter 2141 is provided with a supporting wall 2142 facing the first fixing member 215, and the first fixing member 215 is provided with a fixed wall 2152 facing the supporting wall 2142. The fixed wall 2152 is provided with a supporting portion 2153, which protrudes from the fixed wall 2152 and is used to elastically support the supporting wall 2142. When the adapter 2141 rotates relative to the projection body 211 with the projection direction as the rotation axis, the supporting portion 2153 can generate elastic deformation to ensure the rotation of the adapter 2141 relative to the projection body 211. When the adapter 2141 and the projection body 211 are relatively stationary, the supporting portion elastically supports the supporting wall 2142 to keep the adapter 2141 and the first fixing member 215 relatively stationary in the absence of external force, which is beneficial to improving the stability of the projection picture.

[0066] refer to Fig.10In some embodiments, the adapter 214 is further provided with a mounting groove 2143 and a locking mechanism 2144. The mounting groove 2143 is used to accommodate the protrusion on the lamp to ensure the relative stillness of the lamp and the adapter 214. The locking mechanism 2144 is slidably connected to the adapter 214. The locking mechanism 2144 can move toward the direction of the mounting groove 2143 to support or release the lamp, thereby realizing quick disassembly and assembly between the lamp and the mounting base.

[0067] Specifically, the locking mechanism 2144 moves toward the direction close to the mounting groove 2143, and the lamp can be fixed on the adapter 214. At the same time, the protrusion on the lamp is placed in the mounting groove 2143, which can further improve the stability of the installation of the lamp and the adapter 214. Alternatively, the locking mechanism 2144 can move toward the direction away from the mounting groove 2143, so that the protrusion on the lamp can be disengaged from the mounting groove 2143, and the lamp and the adapter 214 can be disassembled.

[0068] refer to Figure 5 and Figure 6 In some embodiments, the projector 200 further includes a light color component 220, which includes a connecting seat 221, a light-transmitting member 222 and a second fixing member 223. The connecting seat 221 is connected to the projection body 211. Along the projection direction, the second fixing member 223 is located on the side of the connecting seat 221 away from the projection body 211. The light-transmitting member 222 is located between the connecting seat 221 and the second fixing member 223. The second fixing member 223 is detachably connected to the connecting seat 221. The connection between the second fixing member 223 and the connecting seat 221 can fix the light-transmitting member 222. The separation of the second fixing seat from the connecting seat 221 can ensure the disassembly of the light-transmitting member 222 to replace or maintain the light-transmitting film. The light-transmitting member 222 is used to receive light transmitted through the light-transmitting film 130 and can change the color of the light. Without replacing the film box 100, the projector 200 can project patterns of multiple different colors.

[0069] Specifically, the light-transmitting member 222 is a colored lens, and the second fixing member 223 and the connecting seat 221 can be connected by magnetic attraction, which is helpful for conveniently replacing different light-transmitting sheets. It should be understood that when taking photos, in order to ensure that the captured images are richer, a variety of light effects of different colors are usually required to fill in the shooting area. The connection between the second fixing member 223 and the connecting seat 221 can realize the convenient replacement of the light-transmitting member 222, which is beneficial to better meet the shooting needs.

[0070] refer to Figure 5 and Figure 6In some embodiments, the projector 200 further includes a zoom assembly 230, which is connected to the projection body 211. Along the projection direction, the film box 100 is used to accommodate the light-transmitting film 130. The zoom assembly 230 is used to receive the light passing through the light-transmitting film 130 and change the focal length of the light. Without changing the shooting distance, setting the zoom assembly 230 can change the projection range of the pattern, which is beneficial to better meet the shooting needs.
