Lateral fingerprint recognition apparatus for electronic device

An electronic device, wherein the electronic device comprises:

• a middle frame connected to a first function button, wherein
• a fingerprint hole is arranged on the middle frame, a fingerprint recognition apparatus passing through the fingerprint hole, wherein the fingerprint recognition apparatus is in contact with the first function button, wherein the fingerprint recognition apparatus comprises an accommodating structure, a fingerprint recognition assembly, a flexible circuit board, and a reinforcement component, wherein the flexible circuit board is arranged between the fingerprint recognition assembly and the reinforcement component, and wherein in a first direction, a size of the reinforcement component is smaller than a size of the fingerprint recognition assembly, so that the fingerprint recognition assembly is assembled from the outside of the middle frame to the inside of the middle frame;
• and
• a stopping assembly arranged on a side of the fingerprint hole close to the first function button, and is connected to the middle frame, wherein the stopping assembly comprises a retaining wall structure, and the retaining wall structure is partly inserted into the accommodating structure;
• and wherein
• in the first direction, a size of a partial area is smaller than a size of movement space, and the movement space comprises space of the accommodating structure on the side of the fingerprint hole close to the first function button;
• and
• in a second direction of a first plane and/or a third direction of the first plane, a size of the retaining wall structure is greater than a size of the fingerprint hole, wherein the first direction is perpendicular to the side surface of the middle frame, the first plane is parallel to the side surface of the middle frame, the second direction is a thickness direction of the middle frame, and the third direction is perpendicular to the second direction.
