AI Technical Summary
The existing method of pre-fixing the charging box with magnets is cumbersome and causes the quick-drying adhesive to turn white, resulting in inconvenience in operation and poor performance.
The charging case is designed with a groove, and the inner sidewall of the groove has a protrusion to achieve an interference fit with the magnet, simplifying the pre-fixing process of the magnet.
The raised design on the inner wall of the groove enables rapid pre-fixation of the magnet, simplifies the operation, improves installation efficiency, and avoids the whitening of the quick-drying adhesive.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to a charging box technical field especially relates to a magnet pre -fixing structure of charging box. BACKGROUND
[0002] The magnet of the prior art charging box is generally fixed by yellow glue at the periphery, but the yellow glue needs to be dried for 6-8 hours, in order to prevent the magnet from rebounding during the drying process and causing poor performance, the magnet needs to be pre-fixed, usually by the following two ways:
[0003] 1. First, pre-fix the magnet to the inner lower shell by fast-drying glue at the bottom of the magnet, and then fix it by yellow glue around the upper surface of the magnet.
[0004] 2. First, pre-fix the magnet to the inner lower shell by UV glue at two points around the magnet, and then fix it by yellow glue around the magnet.
[0005] However, the fast-drying glue pre-fixing and UV glue pre-fixing processes are relatively complicated, and the surface of the fast-drying glue will appear white after drying. INVENTION CONTENTS
[0006] The utility model solves the technical problem of providing a magnet pre-fixing structure of a charging box, which is simple to operate and can quickly pre-fix the magnet.
[0007] In order to solve the above technical problems, the utility model discloses a magnet pre-fixing structure of a charging box, which comprises a groove provided in the charging box, and the groove is used for placing a magnet; a protrusion is provided on the inner side wall of the groove, and the protrusion is used for making the groove and the magnet to be placed in interference fit.
[0008] As an optional embodiment, the protrusion is in the shape of a strip.
[0009] As another optional embodiment, the protrusion is in the shape of a triangular prism, and one side of the protrusion is fixed to the inner side wall of the groove.
[0010] As another optional embodiment, the height of the protrusion is 0.01-0.5mm.
[0011] As another optional embodiment, the base length of the triangular cross section of the triangular prism is 0.1-1mm.
[0012] As another optional embodiment, the size of the protrusion and the groove is designed to make the groove and the magnet to be placed in interference fit, and the size tolerance of the interference fit is 0.04-0.06mm.
[0013] As a further alternative embodiment, a fixing adhesive is also included, which is arranged at the edge of the surface of the magnet that has been placed in the groove.
[0014] Compared with the prior art, the embodiments of the utility model have the following beneficial effects:
[0015] The utility model discloses embodiments through the design of the protrusion in the inner wall of the recess, make magnet can pre-clamping in the recess, compared with the mode of operation of the fixed point more simple, can improve installation efficiency. BRIEF DESCRIPTION OF DRAWINGS
