Description

Technical Field

[0001] The utility model relates to the technical field of projection, in particular to a rotational projection imaging device. Background Art

[0002] This utility model patent application is an iterative update of the technical solutions of the patented technology of the Chinese invention patent, authorization announcement number: CN118197177B and the Chinese utility model patent application, application number: 202422711125.7, especially focusing on the protection of the technical innovation of the above two technical solutions in the shell.

[0003] The above invention patent technology and utility model patent application scheme both mention the housing of the imaging device, which can be roughly described as follows: the upper housing and the lower housing are assembled and connected to form a semi-enclosed spherical housing, and both the upper housing and the lower housing are hemispherical structures. Therefore, it can be seen that:

[0004] The aforementioned imaging device is generally spherical in shape. While it can achieve a rotating projection imaging effect, it is primarily suspended from buildings or landscape trees. This spherical shape inevitably occupies a large space and is not conducive to presenting large-scale or complete dynamic images to viewers. Furthermore, the threaded sealing connection between the upper and lower housings of the aforementioned imaging device creates difficulties during assembly, hindering efficient manufacturing.

[0005] Therefore, it is necessary to propose a rotational projection imaging device that overcomes the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0038] like Figures 1 to 3 As shown, in one embodiment of the present application, a rotational projection imaging device includes a transparent upper shell 1, an intermediate shell 2, a lower shell 3 and a neck shell 4. The upper shell 1, the intermediate shell 2, the lower shell 3 and the neck shell 4 are assembled and connected to form a closed shell 5. The upper shell 1 is provided with a neck shell 4 at the end away from the intermediate shell 2. The neck shell 4 and the upper shell 1 are integrally formed, and the intermediate shell 2 and the lower shell 3 are integrally formed. The end of the upper shell 1 away from the neck shell 4 is clamped and sealed with the intermediate shell 2. A fixing seat 11 is installed on the inner top surface of the upper shell 1, and a rotating mechanism 12 and an imaging mechanism 14 are installed on the fixing seat 11. The rotating mechanism 12 is connected to a rotating bracket 13 that is compatible with the intermediate shell 2 and the lower shell 3. A strip-shaped light-emitting body 131 is provided on the outer peripheral surface of the rotating bracket 13. The strip-shaped light-emitting body 131 is electrically connected to the imaging mechanism 14. The upper shell 1 and the lower shell 3 are both hollow hemispherical structures, and the intermediate shell 2 is a hollow cylindrical structure.

[0039] On the one hand, in this embodiment, the upper shell, the middle shell, the lower shell and the neck shell are assembled and connected to form a closed shell. The neck shell and the upper shell are integrally formed, and the middle shell and the lower shell are integrally formed. In addition, the upper shell and the middle shell are snap-fitted and sealed. Since the middle shell and the lower shell are integrally formed, and the upper shell and the middle shell are snap-fitted and sealed, the structure of the entire closed shell has better stability and sealing. At the same time, it is convenient for workshop personnel to snap-fit ​​and assemble the upper shell and the middle shell, thereby improving the efficiency of shell assembly.

[0040] On the other hand, in this embodiment, the middle shell is designed as a hollow cylindrical structure, and the upper shell and the lower shell are both designed as hollow hemispherical structures, making the imaging device appear more slender. Unlike spherical imaging devices, it does not occupy a large space and is convenient for suspension in narrow spaces such as buildings or landscape trees.

[0041] In addition, the connection and assembly form between the hemispherical upper and lower shells and the cylindrical middle shell of this embodiment, such as: an integrated molding connection method, a sealed snap-on assembly method, can make the imaging surface of the imaging device as a whole appear in the form of a slender strip structure, which is conducive to projecting dynamic images in a large format or completely and fully in front of the viewer.

[0042] like Figures 4 to 7 As shown, in the above embodiment, optionally, the end of the upper shell 1 away from the neck shell 4 is snap-fitted with the middle shell 2, and a UV sealing curing glue 7 is applied between the snaps of the upper shell 1 and the middle shell 2. The UV sealing curing glue 7 is transparent.

[0043] In this embodiment, the upper shell and the middle shell are assembled by snap-fitting, and UV sealing curing glue is applied at the snap-fitting position, so that the upper shell and the middle shell are sealed. This not only strengthens the connection firmness between the two shells, but also achieves the airtightness of the connection between the shells. The effect is better and the assembly is easy to achieve. The UV sealing curing glue is made of transparent material, which can improve the transparency of the connection between the upper shell and the middle shell without affecting the penetration of the light beam.

[0044] like Figures 1 to 3 、 Figure 8 and Figure 9 As shown, in the above embodiment, optionally, a bearing base 31 is provided on the inner bottom surface of the lower shell 3, and the bearing base 31 is provided with a receiving groove 32. The receiving groove 32 can accommodate a rolling bearing (not shown in the figure), and the bearing base 31 is in contact with the outer surface of the rolling bearing. A threading channel 41 for accommodating the threading of a cable is provided in the neck shell 4, and a waterproof connector 42 is provided in the threading channel 41. A sealant 43 is filled between the waterproof connector 42, the threading channel 41 and the cable to enable the neck shell 4 to be sealed. The sealant 43 is transparent.

[0045] In this embodiment, a bearing base is provided on the inner bottom surface of the lower shell, and a receiving groove is opened in the bearing base to provide a structural basis for the rotation of the rotating bracket connected to the rotating mechanism. In addition, transparent sealant is filled between the waterproof joint, the wire threading channel and the cable, which can not only achieve a waterproof sealing effect, but also does not hinder the light beam from penetrating the shell.

[0046] like Figures 1 to 3 As shown, in the above embodiment, optionally, a suspension bracket 6 is connected to the neck shell 4, and the suspension bracket 6 is designed in a "J"-shaped structure;

[0047] In this embodiment, the hanging bracket adopts a "J"-shaped structure design, which is convenient for lifting and easier for threading and hanging, and is an option of conventional technical means.

[0048] like Figures 1 to 3As shown, in the above embodiment, optionally, the diameters of the upper shell 1, the middle shell 2 and the lower shell 3 are all 50 to 500 mm;

[0049] In this embodiment, in order to cater to the market's considerations on the structural aesthetics of the product, the structural bearing capacity of the shell device itself, and the relative stability of the structure, reasonable parameters are selected for the diameter of the spherical shell to improve the structural performance, aesthetics, and market acceptance of the shell device.

[0050] like Figures 1 to 3 As shown, in the above embodiment, optionally, the end of the neck shell 4 close to the upper shell 1 is designed as a trumpet-shaped structure, and the neck shell 4, the upper shell 1, the middle shell 2 and the lower shell 3 are smoothly connected;

[0051] In this embodiment, the neck shell adopts a trumpet-shaped structural design, so that the neck shell can have a structural basis for smooth connection with the upper shell. This is a conventional technical means. Through the smooth connection design between the shells, the overall aesthetics of the outer shell device can be improved. In addition, the smooth surface of the connection can improve the light transmittance efficiency of the light beam, and the light beam is more concentrated.

[0052] like Figures 1 to 3 As shown, in the above embodiment, further optionally, the upper shell 1, the middle shell 2, the lower shell 3 and the neck shell 4 are all made of transparent plastic material;

[0053] In this embodiment, the upper shell, the middle shell, the lower shell and the neck shell are made of transparent plastic material, which can improve the overall light transmittance of the housing device.

[0054] like Figures 1 to 3 As shown, in the above embodiment, further optionally, the rolling bearing is provided at one end of the rotating bracket 13 away from the fixed seat 11;

[0055] In this embodiment, a rolling bearing is arranged at one end of the rotating bracket. When the rotating bracket rotates, the rolling bearing on its end is accommodated in the accommodating groove of the bearing base. The rolling bearing is in contact and connected with the bearing base, thereby limiting the swing amplitude generated by the rotating bracket during the rotation process and improving the rotation stability of the rotating bracket.

[0056] like Figures 1 to 3 As shown, in the above embodiment, the imaging mechanism 14 optionally includes a driving control board 141 capable of controlling the rotation of the rotating mechanism 12 and controlling the imaging display of the imaging mechanism 14, and the driving control board 141 is electrically connected to the strip-shaped light-emitting body 131;

[0057] In this embodiment, the rotation mechanism, imaging mechanism and strip light-emitting body are controlled by the driving control board, so that the strip light-emitting body on the rotating bracket can rotate along with the rotating bracket under the drive of the rotation mechanism, providing driving force and imaging light source.

[0058] like Figures 4 to 7 As shown, in the above embodiment, further optionally, a male buckle 15 is provided on the outer periphery of one end of the upper shell 1 away from the neck shell 4, and a female buckle 21 is provided on the outer periphery of one end of the intermediate shell 2 close to the upper shell 1. The male buckle 15 and the female buckle 21 are matched and plugged together, and the clamping portion between the male buckle 15 and the female buckle 21 is coated with UV sealing curing glue 7;

[0059] In this embodiment, the male buckle of the upper shell and the female buckle of the middle shell are matched and plugged in, and UV sealant is applied at the joint. This not only improves the relative structural stability and sealing between the upper shell and the middle shell, but also facilitates the workshop personnel to snap together the upper shell and the middle shell, thereby improving the shell assembly efficiency.

[0060] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure made using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
