Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a capsule core and a capsule endoscope. Background Art

[0002] An important part of the capsule core is the light board. During the installation process, the light board will be electrically connected to the lens base plate using an FPC flexible flat cable. At the same time, because the light board is installed at the front end of the capsule endoscope, it is also necessary to fold the light board onto the lens base plate. At this time, the light board will rebound and warp up under the memory of the FPC flexible flat cable if it is not fixed. After the rebound, it will bring inconvenience to production and assembly, and affect the assembly accuracy and efficiency. In the prior art, some manufacturers use bonding to fix the light board on the lens base, and then install the light board cover to control the rebound of the light board. However, this method uses a long FPC flexible flat cable, which will interfere with the side wall of the light board cover, making assembly inconvenient and possibly causing damage to parts.

[0003] Therefore, those skilled in the art are committed to developing a light board fixing structure and a capsule endoscope in which the FPC flexible flat cable does not interfere with the light board cover. Utility Model Content

[0004] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is to provide a capsule core and a capsule endoscope which are easy to assemble and in which the FPC flexible flat cable does not interfere with the light board cover.

[0005] To achieve the above-mentioned purpose, the present invention provides a capsule core, comprising a mirror base plate and a lamp board connected by an FPC, the lamp board is provided with an inner hole, the mirror base plate is provided with a lens, the lens passes through the inner hole, and the base of the lens is provided with a fixing device that cooperates with the lamp board and is used to install the lamp board on the base of the lens. The present invention fixes the lamp board on the lens base by the fixing device, which can prevent the lamp board from rebounding and warping.

[0006] Preferably, the fixing device is a connecting seat arranged on the surface of the lens base.

[0007] Preferably, the connecting seat and the base of the lens are an integrated structure.

[0008] Preferably, the connecting seat and the base of the lens are fixedly connected via a connecting device.

[0009] Preferably, the inner side of the connecting seat is close to the lens side, and the outer side surface of the connecting seat is used to cooperate with the inner hole to limit and fix the light board.

[0010] Preferably, the inner hole length L is greater than the maximum outer diameter D of the lens. With such a design, when the light board is folded toward the lens, the lens can still pass through the inner hole smoothly without interfering with the lens. At the same time, the length of the FPC flexible cable can be reduced, and the light board cover and the FPC flexible cable will not interfere with each other.

[0011] Preferably, the inner hole is elliptical, and the length L of the major axis of the inner hole is greater than the maximum outer diameter D of the lens.

[0012] Preferably, the inner hole and the connecting seat are interference fit, and the height of the connecting seat is lower than the lens.

[0013] Preferably, it further comprises a lamp board cover, wherein the middle lens hole of the lamp board cover is interference fit with the lens, and the bottom surface of the lamp board cover covers the lamp board.

[0014] The present invention also provides a capsule endoscope, comprising the capsule core as described above.

[0015] The beneficial effects of the present invention are: the present invention can effectively prevent the light board from rebounding, does not need to use adhesives or other connection structures, has a simple structure, can improve production efficiency and assembly accuracy, and is relatively convenient for repair. At the same time, the light board can be smoothly folded and the light board cover does not interfere with the FPC flexible cable. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that in the description of the present invention, the directions or positional relationships indicated by the terms "upper", "lower", "left", "right", "inside", "outside", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific manner, and therefore cannot be understood as a limitation on the present invention.

[0021] like Figures 1 to 4As shown, a capsule core comprises a lens base plate 1 and a light board 2 connected by an FPC 3, the light board 2 is provided with an inner hole 21, the lens base plate 1 is provided with a lens 13, the lens 13 passes through the inner hole 21, and the base of the lens 13 is provided with a fixing device that cooperates with the light board 2 and is used to install the light board 2 on the base of the lens 13. Figure 4 As shown, in this embodiment, the fixing device is a connecting seat 11 arranged on the surface of the base of the lens 13. The connecting seat 11 and the base of the lens 13 can be an integral structure, or they can be fixedly connected by a connecting device, such as by screws or adhesive. The inner side of the connecting seat 11 is close to the side of the lens 13, that is, the inner side of the connecting seat 11 is conformally matched with the side of the lens, and the outer side of the connecting seat 11 is used to cooperate with the inner hole 21 to limit and fix the light board 2. In this embodiment, the light board 2 is fixed to the base of the lens 13 by the interference fit between the inner hole 21 and the connecting seat 11, without the use of other devices. At the same time, the height of the connecting seat 11 is lower than the lens 13, which is convenient for the light board to pass through the lens and be fixed to the connecting seat. It can also reduce the length of the FPC 3 and prevent the FPC from interfering with the light board cover 22.

[0022] like Figure 3 As shown, the length L of the inner hole 21 is greater than the maximum outer diameter D of the lens 13. In this embodiment, the inner hole 21 is elliptical, and the length of the inner hole 21 is that the major axis length L is greater than the outer diameter D of the lens 13. This arrangement can reduce the length of the FPC 3, and when the light board 2 is folded toward the lens direction, the lens 13 can still pass through the inner hole 21 smoothly, so that the inner hole 21 and the lens 13 will not interfere with each other, and the light board cover 22 and the FPC 3 will not interfere with each other. Figure 3 As shown in A in the middle.

[0023] The utility model further comprises a lamp board cover 22 , which can further prevent the lamp board 2 from rebounding. The middle lens hole of the lamp board cover 22 is interference-fitted with the lens 13 , and the bottom surface of the lamp board cover 22 covers the lamp board 2 .

[0024] The utility model also provides a capsule endoscope, comprising a capsule core with the above light board fixing structure.

[0025] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
