Description

Protective housing and cell-phone shell The utility model claims priority from chinese patent application No. 2024218190565 filed on 29 th year 2024, month 07, entitled "one kind of mobile phone case with sound Kong Quanbao and scratch resistance", which is incorporated herein by reference in its entirety. Technical Field The application relates to the technical field of electronic product accessories, in particular to a protective shell and a mobile phone shell. Background In the related art, in order to improve the convenience of protective housing and electronic product dismouting, cut on the lower curb plate of protective housing generally for the lower curb plate is interrupted to set up, in order to reduce the hardness of protective housing, but can lead to the curb plate of protective housing not enough intact, the protection dynamics weakens, and the edge of the intermittent part of curb plate very easily scratches user's operation hand etc. that uses experience relatively poor. Disclosure of utility model In order to solve the technical problems, the application provides a protective shell and a mobile phone shell, which are used for improving the protective effect of the protective shell, improving the convenience of disassembly and assembly of the protective shell and solving the problem of scraping of an avoidance groove on a user operator. The application provides a protective shell which comprises a back plate and a frame formed by bending and extending the edge of the back plate towards one side, wherein the frame at least comprises an upper side plate and a lower side plate, an avoidance groove which extends towards the back plate and penetrates through the inner surface to the outer surface of the upper side plate or the lower side plate is formed in one end face, away from the back plate, of the upper side plate or the lower side plate, and the depth of the avoidance groove is smaller than the dimension of the upper side plate or the lower side plate, provided with the avoidance groove, along the depth direction of the avoidance groove. The application provides a mobile phone shell which comprises a rectangular backboard and a frame formed by bending and extending the edge of the backboard towards one side, wherein the frame comprises an upper side plate, a left side plate, a lower side plate and a right side plate which are connected end to end in sequence, a charging port avoiding groove and at least one sound-emitting Kong Birang hole are formed in the lower side plate, the distance between the charging port avoiding groove and the backboard ranges from 0.2mm to 1mm, a second round corner structure is arranged at the corner of the charging port avoiding groove, and the radius of the second round corner structure ranges from 2mm to 3mm. The protective shell has the beneficial effects that the protective shell comprises a back plate and a frame formed by bending and extending the edge of the back plate towards one side, the frame at least comprises an upper side plate and a lower side plate, an avoidance groove which extends towards the back plate and penetrates from the inner surface to the outer surface of the upper side plate or the lower side plate is formed in one end face of the upper side plate or the lower side plate, which faces away from the back plate, and the depth of the avoidance groove is smaller than the dimension of the upper side plate or the lower side plate, which is provided with the avoidance groove, along the depth direction of the avoidance groove. Through the mode, the depth of the avoidance groove is smaller than the dimension of the upper side plate or the lower side plate provided with the avoidance groove along the depth direction, and the avoidance groove is formed in an end face, deviating from the back plate, of the upper side plate or the lower side plate, so that the avoidance groove does not penetrate through the upper side plate or the lower side plate along the depth direction. On one hand, the part of the upper side plate or the lower side plate which is not penetrated can increase the protection effect of the protective shell and the capability of fixing the mobile phone, on the other hand, the arrangement of the avoidance groove can improve the convenience of dismounting the protective shell, on the other hand, the avoidance groove does not penetrate the upper side plate or the lower side plate along the depth direction, so that the upper side plate or the lower side plate is uninterruptedly arranged, the problem of scratching of the avoidance groove on a user manipulator can be solved, and the use experience is improved.
