Description

Technical Field

[0001] This utility model relates to the field of projector technology, and in particular to an image projector for multimedia conferencing. Background Technology

[0002] Conference projectors are visualization devices specifically designed for business meetings. They use optical imaging technology to project electronic content (documents, videos, data, etc.) onto a screen or wall, serving as the core display terminal in modern meeting spaces. Their core value lies in improving information presentation efficiency and optimizing the collaborative experience.

[0003] Existing conference projector lenses protrude, and some lenses are equipped with dust covers. However, the applicant found that dust also adheres to the dust cover itself during use. Since the lens will attract ions during use, the dust on the dust cover will be attracted to the lens, which increases the difficulty of lens protection and care. Utility Model Content

[0004] The purpose of this invention is to provide a DC power supply cabinet with efficient heat dissipation, which has the following advantages.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an image projector for multimedia conferencing, comprising a body and an imaging lens assembly, wherein a lens is disposed on one side of the imaging lens assembly, and further comprising:

[0006] A lens protection mechanism is sleeved around the imaging lens assembly of the device and fixed to the outside of the imaging lens assembly;

[0007] The lens protection mechanism includes a rotating part, a fixed storage part, a driving outward part, and a wrapping part. The fixed storage part is columnar and is fixedly connected to the imaging lens assembly. The fixed storage part is provided with a rotating part. The driving outward part is located in the inner cavity of the fixed storage part. When the rotating part rotates, the driving outward part moves the wrapping part out of the fixed storage part.

[0008] Furthermore, the rotating part includes a rotation drive, which is rotatably connected to the inner wall of the fixed storage part via a bushing.

[0009] Furthermore, the fixed storage part includes a lens cover, which has multiple molding grooves evenly spaced and an inclined guide opening on the outer side of the molding grooves.

[0010] Furthermore, the wrapping portion includes multiple internal first shaping skeletons, each internal first shaping skeleton is made of V-shaped memory metal, and each internal first shaping skeleton has a central expansion skeleton at both ends. Two central expansion skeletons are connected to each other as a whole through an external fitting skeleton. The wrapping portion is petal-shaped, and multiple internal first shaping skeletons are fixedly connected to an annular moving ring.

[0011] Furthermore, the wrapping portion preferably includes a covering film, the covering film comprising an adhesive layer and an outer layer, the adhesive layer being adhered to the surface of the lens.

[0012] Furthermore, the forming groove is a narrow groove, used to compress the packaged portion after it is recycled.

[0013] Furthermore, the drive outward movement portion includes an annular gear ring fixedly connected to the rotary drive, a plurality of first drive gears meshing on the annular gear ring, a second drive gear coaxially connected to the first drive gear, a rack meshing on one side of the second drive gear, and the rack fixedly connected to the annular moving ring.

[0014] Furthermore, the first drive gear and the second drive gear are coaxially connected to the inner wall of the molding groove opened on the lens cover.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] After the projector is used, the rotary drive drives the annular gear ring to rotate synchronously. During the rotation of the annular gear ring, the teeth on the annular gear ring can drive the first drive gear and the second drive gear to rotate synchronously. At this time, the second drive gear drives the rack to move outward axially, and then the multiple wrapped parts on the annular moving ring move outward. After they are released from the compressed state in the forming groove, they move out of the guide port. The guide port can move the wrapped parts towards the surface of the lens, and then the wrapped parts can form a petal-like state to fit the lens. It should be noted that the bonding layer and the outer layer will be attached to the surface of the lens. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1 to 7 The image projector shown in Figure 1 is for multimedia conferencing, comprising a body 1 and an imaging lens assembly 2, wherein a lens 3 is disposed on one side of the imaging lens assembly 2, and further comprising:

[0028] The lens protection mechanism is sleeved around the imaging lens assembly 2 of the device and fixed to the outside of the imaging lens assembly 2;

[0029] The lens protection mechanism includes a rotating part, a fixed storage part, a driving outward part, and a wrapping part. The fixed storage part is cylindrical and is fixedly connected to the imaging lens assembly 2. The fixed storage part is provided with a rotating part. The driving outward part is located in the inner cavity of the fixed storage part. When the rotating part rotates, the driving outward part moves the wrapping part out of the fixed storage part.

[0030] The rotating part includes a rotation drive 5, which is rotatably connected to the inner wall of the fixed storage part via a bushing.

[0031] The fixed storage part includes a lens cover 4, which has multiple molding grooves 6 arranged at equal intervals, and an inclined guide opening 7 is provided on the outside of the molding grooves 6.

[0032] The wrapping part includes multiple internal first shaping skeletons 8, which are V-shaped memory metal. Both ends of the internal first shaping skeletons 8 are provided with central expansion skeletons 9. The two central expansion skeletons 9 are connected into a whole by an external fitting skeleton 10. The wrapping part is petal-shaped, and multiple internal first shaping skeletons 8 are fixedly connected with annular moving rings 18.

[0033] The encapsulation portion includes a cover film 11, which includes an adhesive layer 16 and an outer layer 17. The adhesive layer 16 is bonded to the surface of the lens 3.

[0034] The forming groove 6 is a narrow groove used to compress the wrapped part after it is recycled, so as to ensure that it can be elastically released when it is moved outward and to wrap around the lens 2.

[0035] To ensure that multiple package parts move and are retrieved synchronously, the drive outward part includes an annular gear ring 13 fixedly connected to the rotary drive 5. Multiple first drive gears 12 are meshed on the annular gear ring 13. The first drive gears 12 are coaxially connected to second drive gears 14. A rack 15 is meshed on one side of the second drive gear 14. The rack 15 is fixedly connected to the annular moving ring 18.

[0036] In order to maintain the stability of the rotation of the first drive gear 12 and the second drive gear 14, the first drive gear 12 and the second drive gear 14 are coaxially connected to the inner wall of the molding groove 6 opened on the lens cover 4.

[0037] After the projector is used, the rotary drive 5 is rotated, which drives the annular gear ring 13 to rotate synchronously. During the rotation of the annular gear ring 13, the teeth on the annular gear ring 13 can drive the first drive gear 12 and the second drive gear 14 to rotate synchronously. At this time, the second drive gear 14 drives the rack 15 to move outward axially, and then the multiple wrapped parts on the annular moving ring 18 move outward, and after they are released from the compressed state in the forming groove 6, they move out of the guide port 7. The guide port 7 can move the wrapped parts toward the surface of the lens 3, and then the wrapped parts can form a petal-like state to adhere to the lens 3. It should be noted that the bonding layer 16 and the outer layer 17 will adhere to the surface of the lens 3.

[0038] When the entire encapsulation part is released, a portion of the internal first shaping skeleton 8 is located within the forming groove 6 of the lens cover 4. The forming groove 6 has a space for tightening the encapsulation part, so that both release and retraction can proceed smoothly. The middle expansion skeleton 9 allows the external bonding skeleton 10 to be in a bonded state towards the lens 3 when it is discharged. The middle expansion skeleton 9 is relatively short and located at the tail end of the bonding point of two adjacent encapsulation parts. This also allows the middle expansion skeleton 9 to maintain contact between the two adjacent encapsulation parts through its self-deformation characteristics, thereby ensuring the safety of the lens 3 when it is idle and preventing dust from sticking.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
