In the figure: 1. a silica gel pad; 2. a metal base plate; 3. a convex strip; 4. a cylindrical boss; 5. a closed convex ring; 6. and positioning the through hole.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1 to 2, the present invention provides a technical solution: a controller rear cover device is generally used for an electric bicycle controller, but may also be used for a product having a rear cover and a cushion. The whole rear cover device comprises a metal bottom plate and a silica gel pad matched with the metal bottom plate, wherein the silica gel pad is aligned with the metal bottom plate and fixedly arranged on the metal bottom plate, and the silica gel pad is fixed on the metal bottom plate in advance and serves as an inseparable part; the silica gel pad is used for filling gaps among the metal plate, the circuit board and the upper cover, and has the functions of supporting the circuit board, pressing the power device, insulating, preventing water, preventing dust and the like;
the surface of one side, back to the metal base plate, of the silica gel pad is provided with a convex strip and a columnar boss, the position of the convex strip is arranged corresponding to a power device on the circuit board, the convex strip is a rectangular hollow convex strip, and the convex height of the convex strip is 3mm and is used for compressing the power device;
the cylindrical bosses are provided with a plurality of cylindrical bosses, the end faces of the cylindrical bosses respectively correspond to the surface of the circuit board or abut against the plug-in units connected with the circuit board, the cylindrical bosses are cylindrical solid bosses, and the number of the cylindrical bosses is 16, and the cylindrical bosses are used for supporting the circuit board and the plug-in units.
The silica gel pad is located the positioning hole inboard and encircles and be provided with sealed bulge loop in a side surface edge of metal soleplate dorsad, seals the setting of bulge loop, can make silica gel pad and box body cooperation later stage gap edge seal, plays waterproof effect.
The surface edge of the metal bottom plate and the silica gel pad which are matched with each other is provided with a plurality of positioning through holes in a surrounding mode, the number of the positioning through holes is evenly 8, and the positioning through holes are used for fixing the rear cover and the upper cover through positioning screws.
