To make the objectives, technical solutions, and advantages of this application more clear, the following will further describe the implementation methods of this application in detail with reference to the accompanying drawings.

[0038] In order to solve the problem that the lighting effects of building block toys are relatively simple, this application provides a building block projection lamp. Figures 1 to 10 The building block projection lamp includes a shell 1, a light source 2, a condenser lens 3, a projection film 4 and a projection lens 5, wherein the light source 2, the condenser lens 3, the projection film 4 and the projection lens 5 are arranged in sequence inside the shell 1 along the length direction of the shell 1, and the end of the shell 1 close to the projection lens 5 serves as the projection output surface of the building block projection lamp of the present application, and the other end away from the projection lens 5 is used to connect with other building block structures, so as to construct a projection lamp structure that can be installed on building blocks with different lighting effects through the light source 2, the condenser lens 3, the projection film 4 and the projection lens 5, so as to enrich the usage needs of the building block set toy.

[0039] Specifically, the condenser 3 and the projection lens 5 of the present application both adopt convex lenses, and the light source 2 is set at the focus of the condenser 3, so that the light emitted by the light source 2 passes through the convex lens serving as the condenser 3 and is refracted into light parallel to the main optical axis of the convex lens, and then emitted onto the projection film 4. The content on the projection film 4 is projected onto the convex lens serving as the projection lens 5 under the illumination of light. The projection lens 5 enlarges the content of the projected projection film 4 and then projects it onto the projection display area (such as a projection screen, etc.), thereby realizing diversified lighting play of the building block set toy. The projection content of the building block projection lamp is the same as the content on the projection film 4.

[0040] In addition, the magnification of the projection film 4 by the projection lens 5 is related to the distance between the two. Therefore, the relative distance between the projection film 4 and the projection lens 5 within the housing 1 of the present application is adjustable, thereby adjusting the size of the projected image. In this embodiment, the distance between the projection film 4 and the projection lens 5 is adjustable within a range between one and two focal lengths of the convex lens. The closer the distance is to one focal length, the larger the image size of the projection lens 5. Conversely, the farther the distance between the projection film 4 and the projection lens 5 is, the smaller the image size of the projection lens 5 is. Therefore, by adjusting the distance between the projection film 4 and the projection lens 5 in the present application, the size of the projected image can be adjusted.

[0041] In this embodiment, the housing 1 includes a first barrel 11 and a second barrel 12. The first barrel 11 is inserted into the second barrel 12, and the first barrel 11 and the second barrel 12 are capable of relative axial displacement. The light source 2, condenser lens 3, and projection film 4 are mounted within the first barrel 11, and the projection lens 5 is mounted within the second barrel 12. By axially displacing the first barrel 11 relative to the second barrel 12, the projection film 4 can be moved closer to or further away from the projection lens 5, thereby adjusting the distance between the projection film 4 and the projection lens 5.

[0042] In this embodiment, the outer wall of the first cylindrical body 11 is provided with a first helical structure 111 extending along its length, and the inner wall of the second cylindrical body 12 is provided with a second helical structure 121 that nests and mates with the first helical structure 111. The pitch of the first helical structure 111 is equal to the pitch of the second helical structure 121. Thus, by causing the first cylindrical body 11 and the second cylindrical body 12 to rotate relative to each other, the axial relative displacement between them is adjusted, thereby adjusting the distance between the projection film 4 and the projection lens 5. Preferably, in this embodiment, the first helical structure 111 is configured as a helical groove, and the second helical structure 121 is configured as a helical protrusion that fits within and helically mates with the groove. Alternatively, the same technical effect can be achieved by configuring the first helical structure 111 as a helical protrusion and the second helical structure 121 as a helical groove that mates with the protrusion. The first cylindrical body 11 and the second cylindrical body 12 are maintained in relative stillness by friction between the first helical structure 111 and the second helical structure 121.

[0043] To further enhance the stability of the relative static state of the first barrel 11 and the second barrel 12, this embodiment provides an elastic member between the first helical structure 111 and the second helical structure 121. This elastic member increases the friction between the first helical structure 111 and the second helical structure 121, thereby enhancing the relative static stability of the first barrel 11 and the second barrel 12, and thereby enhancing the stability of the image projected by the projection lamp. The elastic member in this embodiment can be an elastic pad or an elastic ball made of an elastic material such as rubber, silicone, or sponge. In this embodiment, an elastic ball is preferably used, as it has good rolling properties, facilitating the rotation of the second barrel 12 relative to the first barrel 11, and significantly reducing production costs.

[0044] In addition, in other embodiments, a guide groove 115 extending along the length direction of the first cylinder 11 may be provided on the outer side wall of the first cylinder 11, and a guide block 123 extending along the length direction of the second cylinder 12 and insertable into the guide groove 115 may be provided on the inner side wall of the second cylinder 12. The guide block 123 cooperates with the guide groove 115 to realize axial linear movement of the second cylinder 12 relative to the first cylinder 11, so as to achieve the purpose of adjusting the distance between the projection mirror 5 and the projection film 4.

[0045] In this embodiment, in order to further improve the stability of the relative static state of the first cylinder 11 and the second cylinder 12, a locking piece (not shown in the figure) can be further provided on the second cylinder 12. The second cylinder 12 is provided with a locking hole at its end away from the projection lens 5. The locking piece includes a tightening block that is passed through the locking hole and abuts against the first cylinder 11. The tightening block is used to increase the friction between the first cylinder 11 and the second cylinder 12, thereby improving the stability between the first cylinder 11 and the second cylinder 12.

[0046] Because the image projected by the projection lamp is related to the projection film 4, the projection film 4 is detachably connected to the first barrel 11 of the present application. Therefore, different projection images can be achieved by replacing different projection films 4. Specifically, a slot 112 is provided on the side wall of the first barrel 11 for inserting the projection film 4 into the interior of the first barrel 11. A mounting groove 113 for inserting the projection film 4 is provided on the inner side wall of the first barrel 11 at a position corresponding to the slot 112. The projection film 4 is stably placed in the first barrel 11 by being inserted into the mounting groove 113.

[0047] Furthermore, the projection film 4 is provided with a first positioning structure 41, and the first cylindrical body 11 is provided with a second positioning structure 114 within its mounting groove 113, which cooperates with the first positioning structure 41. The cooperation between the first positioning structure 41 and the second positioning structure 114 can position the projection film 4, thereby improving the installation stability of the projection film 4. In this embodiment, the first positioning structure 41 and the second positioning structure 114 can cooperate by means of a snap-fit ​​connection, or can also be fixed by magnetic attraction.

[0048] It should be noted that when the projection film 4 of the present application is installed in the first cylinder 11, the projection film 4 needs to completely cover the internal cross-section of the first cylinder 11 to prevent the light from the light source 2 passing through the condenser 3 from passing through the gap between the projection film 4 and the first cylinder 11, thereby affecting the final imaging effect of the projection film 4.

[0049] The first barrel 11 of the present application is inserted into the second barrel 12. To facilitate insertion of the projection film 4 into the first barrel 11, a placement slot 122 is provided on the sidewall of the first barrel 11. When the second barrel 12 is rotated to a preset position relative to the first barrel 11, the placement slot 122 is connected to the slot 112, thereby allowing the projection film 4 to be inserted into the slot 112 through the placement slot 122 from the outside of the second barrel 12 to complete the installation of the projection film 4. This allows users to easily replace projection films 4 with different contents to meet different usage needs. The preset position of this embodiment is when the axial displacement of the second barrel 12 relative to the first barrel 11 is minimized.

[0050] The second barrel 12 is further provided with a blocking block 123 at the placement groove 122 for blocking the placement groove 122 , thereby improving the stability of the projection film 4 installed in the first barrel 11 and preventing light leakage at the placement groove 122 from affecting the projection effect.

[0051] Please combine Figures 8 to 10 The building block projection lamp of the present application can be installed on different building block structures. A connecting structure 6 for connecting to other building block structures is provided at the end of the shell 1 away from the projection lens 5. That is, in this embodiment, a building block connecting hole 13 is provided at the end of the first cylinder 11 extending out of the second cylinder 12. The connecting structure 6 includes round particle parts, clamping parts or ball shaft parts that can be inserted into the building block connecting hole 13, so that a suitable connecting structure 6 can be selected according to different connection methods with other building block structures, thereby improving the installation application range of the building block projection lamp of the present application.

[0052] In summary, the building block projection lamp of the present application utilizes the imaging principle of a convex lens to project the contents of the projection film 4 onto the projection surface, thereby enriching the lighting effects of the building blocks to meet the needs of diverse lighting effects of the building blocks and improving the fun of the building block set toys. In addition, two convex lenses are used for projection in this embodiment, which can obtain a clearer projection picture.

[0053] The building block projection lamp of the present application adjusts the axial distance between its projection film 4 and projection lens 5 by adjusting the relative axial displacement of the first cylinder 11 and the second cylinder 12, thereby being able to change the size of the projected image to meet different projection image requirements.

[0054] The projection film 4 of the present application is detachably connected to the first cylinder 11, so that it is convenient to replace the projection film 4 with different contents to obtain different projection images and meet the different usage needs of users.

[0055] The present application also relates to a building block set, which includes building blocks and the building block projection lamp as described above. The building block projection lamp is detachably connected to the building blocks, so that the building block projection lamp can be easily installed on different building blocks and can be reused. In addition, the building block projection lamp of the present application has a simple structure, a small size, and is easy to carry and move. Users can place it in any position as needed and obtain different projection effects by adjusting the distance from the projection surface to meet the lighting effect requirements in different scenes.

[0056] The above description is only part of the implementation methods of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
