[0035] Clearly and completely describe the technical scheme in the embodiments of the utility model with reference to the drawings in the embodiments of the utility model, obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor belong to the scope of the utility model protection.

[0036] The core of the utility model provides a kind of capsule endoscope, can improve the assembly efficiency of capsule endoscope.

[0037] The specific embodiment one of the capsule endoscope provided by the utility model, please refer to Figures 1 to 12 , including capsule shell 1, capsule core 2 and lamp panel cover 3.Capsule core 2 and lamp panel cover 3 are fixed in capsule shell 1.

[0038] As shown in Figure 1 , capsule shell 1 includes capsule rear shell 11 and optical front cover 12.Capsule rear shell 11 is open 111 in axial one end, the other end is closed end 112, optical front cover 12 is covered in opening 111, and capsule core 2 and lamp panel cover 3 are fixed in the inner cavity formed by capsule rear shell 11 and optical front cover 12.

[0039] As shown in Figure 3 And Figure 4 , the inner wall of capsule rear shell 11 is provided with first rotation limiting structure, which starts from opening 111 and extends to closed end 112 along the axial direction.A plurality of axial limiting blocks 114 are sequentially arranged on the inner wall of capsule rear shell 11 in the circumferential direction, and the number of axial limiting blocks 114 can be set as required, for example, two or three or other number.

[0040] It should be noted that the plurality of axial limiting blocks 114 are sequentially arranged in the circumferential direction, which means that the angle relative to the axial line of the capsule rear shell 11 (usually also the axial line of the capsule endoscope, parallel to Z axis) is different, and in the axial direction, according to the shape of the capsule core 2, the distance from the opening 111 can be the same or different, as long as each axial limiting block 114 can be matched with the capsule core 2 along the axial direction.

[0041] As shown in Figure 2 , the outer circumferential surface of capsule core 2 is provided with second rotation limiting structure, and capsule core 2 is inserted into capsule rear shell 11 along the axial direction through opening 111. Among them, the first rotation limiting structure is rotation limiting rib 113, and the second rotation limiting structure is rotation limiting groove 271 inserted and matched with rotation limiting rib 113 along the axial direction, so as to avoid the rotation of capsule core 2 in capsule rear shell 11 by the insertion and matching of rotation limiting rib 113 and rotation limiting groove 271. In other embodiments, the first rotation limiting structure can also be set as rotation limiting groove, and the second rotation limiting structure is set as rotation limiting rib inserted and matched with the rotation limiting groove.

[0042] As shown in Figure 1 , the lamp cover 3 is arranged at the opening 111, and the lamp cover 3 cooperates with the axial limiting block 114 to limit the capsule core 2 on both sides in the axial direction.

[0043] In the assembly, the capsule core 2 is first installed in the capsule rear shell 11. Since the limiting rotation rib 113 can be seen from the opening 111 of the capsule rear shell 11, the alignment of the limiting rotation groove 271 on the capsule core 2 and the limiting rotation rib 113 of the capsule rear shell 11 is facilitated, and the capsule core 2 can also be prevented from rotating in the capsule shell 1. Since the inner wall of the capsule rear shell 11 is provided with a plurality of circumferentially arranged axial limiting blocks 114, the depth of the capsule core 2 axially entering the capsule shell 1 can be limited, the impact damage of the capsule core 2 with the inner wall of the capsule rear shell 11 can be avoided, and the stability of the capsule core 2 placed in the capsule rear shell 11 can be ensured by the cooperation of the plurality of axial limiting blocks 114 supporting the capsule core 2. Then, the lamp cover 3 is installed on the opening 111 of the capsule rear shell 11, and the optical front cover 12 is closed, and the assembly is completed. The lamp cover 3 can cooperate with the axial limiting block 114 to limit the capsule core 2 axially, so as to prevent the capsule core 2 from moving axially in the capsule shell 1. Based on the limiting effect of the capsule rear shell 11, the capsule endoscope is easy to assemble, the assembly efficiency can be improved, and the assembly precision and the finished product rate of part forming can be improved.

[0044] In order to further improve the assembly efficiency, as shown in Figure 2 and Figure 3 , the limiting rotation rib 113 and the limiting rotation groove 271 are each provided with one, compared with providing a plurality of limiting rotation ribs 113 or limiting rotation grooves 271, the capsule core 2 in the capsule rear shell 11 only has one installation angle, which has a foolproof effect.

[0045] Among them, as shown in Figure 2 , Figure 3 and Figure 5 , in the direction (negative direction of Z axis) of the axial direction pointing to the closed end 112, the circumferential width of the limiting rotation rib 113 and the limiting rotation groove 271 increases continuously, at this time, the limiting rotation rib 113 and the limiting rotation groove 271 are conical structures, which can play a guiding role in the assembly process of the capsule core 2. Of course, in the embodiment in which the first limiting rotation structure is the limiting rotation groove and the second limiting rotation structure is the limiting rotation rib, the circumferential width of the limiting rotation rib 113 and the limiting rotation groove 271 gradually increases in the direction away from the closed end 112 in the axial direction.

[0046] Among them, as shown in Figure 3As shown, the limit rotation rib 113 and the limit rotation groove 271 are formed in the radial direction to limit the radial movement of the capsule core 2 relative to the capsule rear shell 11. Specifically, the limit rotation groove 271 is at least partially tapered in the axial direction, the outer surface of the limit rotation rib 113 includes a first side surface 1131 and two opposite second side surfaces 1132, the first side surface 1131 is connected to the inner wall of the capsule rear shell 11 at both ends in the circumferential direction through the two second side surfaces 1132 respectively, and the two second side surfaces 1132 are gradually close to each other in the axial direction along the direction away from the first side surface 1131, cooperating with the tapered part of the limit rotation groove 271 to achieve the radial anti-disengagement between the limit rotation groove 271 and the limit rotation rib 113. At this time, even if there is extra space in the radial direction in the capsule rear shell 11, the radial movement of the capsule core 2 can be avoided due to the radial limiting effect of the limit rotation groove 271 and the limit rotation rib 113.

[0047] For the structural arrangement of the capsule core 2, as shown, Figures 5 to 11 the lamp panel 21, the first PCB board 22, the battery 24 and the second PCB board 25 are arranged in the direction (negative direction of Z axis) of the closed end 112 of the capsule rear shell 11 in sequence in the axial direction.

[0048] Between the lamp panel 21 and the first PCB board 22, as shown, Figure 7 the side surface of the lamp panel 21 is electrically connected to the lamp panel 21 through the first FPC 28. The camera 221 is arranged on the first PCB board 22, specifically on the axial end surface of the first PCB board 22 away from the closed end 112. Specifically, as shown, Figure 6 the camera 221 includes a lens barrel 2211, and the axial direction of the lens barrel 2211 is parallel to the axial line of the capsule rear shell 11.

[0049] Among them, for the assembly of the camera 221, as shown, Figure 6 and Figure 9 the lamp panel cover 3 is provided with a lamp panel cover through hole 31, and the lamp panel 21 is provided with a lamp panel hole 211, and the camera 221 enters the lamp panel cover through hole 31 in the axial direction through the lamp panel hole. Specifically, the lens barrel 2211 of the camera 221 enters the lamp panel cover through hole 31 in the axial direction through the lamp panel hole.

[0050] Among them, as shown, Figure 6 the camera 221 is in interference fit with the hole wall of the lamp panel cover through hole 31. At this time, the lamp panel cover through hole 31 is in non-clearance fit with the camera 221, and after the lamp panel cover 3 is matched with the camera 221, the lamp panel 21 will not be flipped or popped up under the action of the first FPC 28, thereby fixing the lamp panel 21 to the first PCB board 22. Specifically, the lamp panel cover through hole 31 is a circular hole, and the diameter of the part of the camera 221 extending into the lamp panel cover through hole 31 is the same as the diameter of the lamp panel cover through hole 31.

[0051] Among them, asFigure 6 As shown, the camera 221 extends axially from the end near the closed end 112 through the lamp cover through hole 31 on the lamp cover 3. In other embodiments, the camera 221 may also be configured such that the axial end face of the camera 221 away from the closed end 112 is flush with the axial end face of the lamp cover through hole 31 away from the closed end 112. That is, in the positive Z-axis direction, the height of the light-shielding ring 32 of the lamp cover 3 is less than or equal to the top surface of the camera 221 to avoid affecting the imaging of the camera 221.

[0052] Among them, such as Figure 5 and Figure 9 As shown, the light plate 21 is provided with an elliptical light plate hole 211. The lens barrel 2211 of the camera 221 enters the light plate cover through hole 31 along the axial direction through the light plate hole 211. The accommodating space in the light plate hole 211 is larger than the assembly requirements of the lens barrel 2211, which makes it easier for the light plate 21 to be folded onto the camera 221, thus facilitating assembly.

[0053] Between the first PCB board 22, the battery 24, and the second PCB board 25, such as Figures 6 to 8 As shown, the first PCB board 22 is electrically connected to the second PCB board 25 via the second FPC 29. The first FPC 28 and the second FPC 29 are FPC flexible flat cables. The first PCB board 22, the second PCB board 25, and the battery 24 are respectively connected by springs 26, and an insulating gasket 23 is sandwiched between the first PCB board 22 and the battery 24. Specifically, the insulating gasket 23 has through holes to avoid the springs 26 between the first PCB board 22 and the battery 24.

[0054] In a conventional capsule endoscope, electronic components are mounted on the two axial ends of a second PCB board 25, while the first PCB board 22 has electronic components mounted on its axial end face away from the closed end 112, and its other axial end face directly contacts the battery 24. If the solder mask on the first PCB board 22 is damaged or not properly covered, the first PCB board 22 may come into direct contact with the battery 24, causing a short circuit. This embodiment improves the safety of capsule endoscope use by adding an insulating gasket 23 for isolation. Simultaneously, the insulating gasket 23 can also be used to provide balance for the spring 26.

[0055] Among them, such as Figure 5As shown, the capsule core further comprises a support 27 arranged outside the battery 24. The first PCB board 22 and the second PCB board 25 are mounted at two ends of the support 27 in the axial direction, for example, can be abutted at two ends of the support 27. At this time, the support 27 provides a carrier for the first PCB board 22, the second PCB board 25 and the battery 24, and the support 27 can be fixedly connected with the first PCB board 22 and the second PCB board 25, so that the first PCB board 22, the second PCB board 25 and the battery 24 become an integral whole, and the electronic devices between the first PCB board 22 and the second PCB board 25 are hollowed out, so that the electronic devices are not in direct contact and extrusion with the battery 24, and the electronic devices can be protected.

[0056] As shown in FIG. 6, the support 27 is arranged on the outer circumferential surface of the capsule core 2. Figure 5 As shown in FIG. 6, the support 27 is arranged on the outer circumferential surface of the capsule core 2.

[0057] As shown in FIG. 6, the support 27 is arranged on the outer circumferential surface of the capsule core 2. Figure 5 As shown in FIG. 6, the support 27 is arranged on the outer circumferential surface of the capsule core 2.

[0058] As shown in FIG. 6, the support 27 is arranged on the outer circumferential surface of the capsule core 2. Figure 4 and Figure 5 As shown in FIG. 6, the support 27 is arranged on the outer circumferential surface of the capsule core 2.

[0059] As shown in FIG. 6, the support 27 is arranged on the outer circumferential surface of the capsule core 2. Figure 5 As shown in FIG. 6, the support 27 is arranged on the outer circumferential surface of the capsule core 2.

[0060] As shown in FIG. 6, the support 27 is arranged on the outer circumferential surface of the capsule core 2. Figure 12As shown, corresponding edges can be provided on the capsule rear shell 11 and the optical front cover 12, so that the lamp cover 3 is axially fixed by the clamping of the capsule rear shell 11 and the optical front cover 12. At this time, the distance between the lens in the capsule core 2 and the optical front cover 12 can be limited, which has the function of fixing the focal length.

[0061] Among them, the lamp cover 3 is provided with a marking structure 34 on the surface facing the optical front cover 12. The position and style of the marking structure 34 can be set as needed. The marking structure 34 can correspond to the position or angle of the selected electronic device in the capsule core, so as to know the relative position of the device in the capsule core 2 and the capsule back shell 11 after the capsule core 2 is assembled into the capsule back shell 11, which facilitates the power-off control of the capsule endoscope.

[0062] Among them, such as Figure 12 As shown, the lamp cover 3 includes a light-shielding ring 32 and an outer ring plate 33 fixed to the outer circumferential surface of the light-shielding ring 32 and near the closed end 112. The inner hole of the light-shielding ring 32 is a through hole 31 for the lamp cover. The marking structure 34 is provided on the axial end face of the outer ring plate 33 away from the closed end. In addition, an illumination lamp 212 can be provided on the lamp plate 21, and a lamp hole is provided on the outer ring plate 33. The diameter of the light-shielding ring 32 is designed according to the position, size, and luminous intensity of the illumination lamp 212 of the capsule core 2. At this time, the lamp cover 3 can cover at least part of the lamp plate 21.

[0063] Specifically, for the axial fixation of the capsule core 2, the capsule core 2 is limited and fixed in the negative Z-axis direction by the axial limiting block 114, and in the positive Z-axis direction by the outer ring plate 33.
