Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0043] The core of the present utility model is to provide a capsule core device, which can fix the planar mounting position of the first circuit board relative to the second circuit board, and prevent the second circuit board from warping relative to the first circuit board through the tab.

[0044] Another core of the present utility model is to provide a capsule endoscope including the above-mentioned capsule core device.

[0045] This specific embodiment discloses a capsule core device, which includes a power supply member 100, a first circuit board 200, and a second circuit board 300; a first tab 110 is provided at one axial end of the power supply member 100; the first circuit board 200 is mounted at one axial end of the power supply member 100; the second circuit board 300 is disposed on the side of the first circuit board 200 away from the power supply member 100 and is connected to the first circuit board 200 through an FPC flexible cable 400; components protruding are provided on the surface of the first circuit board 200 facing the second circuit board 300, and the second circuit board 300 is provided with a limiting member for limiting the position of the components to limit the planar mounting position of the first circuit board 200 relative to the second circuit board 300; a first connection position and a second connection position are provided along the extending direction of the first tab 110, the first circuit board 200 is fixedly connected to the first connection position, and the second circuit board 300 is fixedly connected to the second connection position.

[0046] It should be noted that the limiting member mentioned in this specific embodiment is mainly used to limit the mounting position of the second circuit board 300 relative to the first circuit board 200 in the plane where the first circuit board 200 is located, to prevent the second circuit board 300 from displacing relative to the first circuit board 200 in the plane where the first circuit board 200 is located; the bonding and fixing member is mainly used to limit the mounting position of the second circuit board 300 relative to the first circuit board 200 perpendicular to the plane where the first circuit board 200 is located, so as to limit the distance between the second circuit board 300 and the first circuit board 200 in the direction perpendicular to the plane where the first circuit board 200 is located.

[0047] The component mentioned in this specific embodiment may be a CPU chip 220, or other structures that meet the requirements, which is specifically determined according to the actual situation and will not be elaborated here.

[0048] In the process of using the capsule core device provided by this specific embodiment, during the installation of the first circuit board 200 and the second circuit board 300 connected by the FPC flexible cable 400, first, the first circuit board 200 needs to be fixed to one end of the power supply member 100 where the first tab 110 is installed, and the first connection position of the first tab 110 is fixedly connected to the first circuit board 200; then the second circuit board 300 is installed. During the installation of the second circuit board 300, the positions of the components are limited by the limiting member. Since the components are fixed to the first circuit board 200, the planar installation position of the second circuit board 300 relative to the first circuit board 200 is limited; the planar installation position mentioned here refers to the installation positions of the second circuit board 300 relative to the first circuit board 200 in the x-direction and the y-direction, where the x-direction and the y-direction are two mutually perpendicular directions in the plane where the first circuit board 200 is located.

The Z-direction here is the direction perpendicular to the plane where the x-direction and the y-direction are located, so as to prevent the second circuit board 300 from tilting relative to the first circuit board 200.

[0049] Compared with the prior art, the capsule core device provided by this specific embodiment can fix the first circuit board 200 relative to the second circuit board 300 in the planar installation position and the vertical installation position, and can prevent the first circuit board 200 from tilting relative to the second circuit board 300.

And because the end of the first tab 110 is provided with a first bending section 1201, during actual use, the first bending section 1201 is pressed against the surface of the second circuit board 300 facing away from the first circuit board 200, which can effectively prevent the second circuit board 300 from tilting relative to the first circuit board 200.

[0054] Furthermore, a first limiting bend and a second limiting bend can be provided on the first tab 110.

As Figure 3 shown, the first limiting protrusion 320, the second limiting protrusion 330, the third limiting protrusion 340, and the fourth limiting protrusion 350 are all electrical components installed on the second circuit board 300. Among them, the first limiting surface of the first limiting protrusion 320, the second limiting surface of the second limiting protrusion 330, the third limiting surface of the third limiting protrusion 340, and the fourth limiting surface of the fourth limiting protrusion 350 are respectively in contact with the four side surfaces of the CPU chip 220 to limit the installation position of the CPU chip 220, thereby limiting the planar installation position of the second circuit board 300 relative to the first circuit board 200.

[0061] Furthermore, guide inclined surfaces can be provided at one ends of the first limiting protrusion 320, the second limiting protrusion 330, the third limiting protrusion 340, and the fourth limiting protrusion 350 facing the first circuit board 200, so that the component enters the space surrounded by the first limiting protrusion 320, the second limiting protrusion 330, the third limiting protrusion 340, and the fourth limiting protrusion 350, and the assembly efficiency of the first circuit board 200 and the second circuit board 300 is improved.
