Abstract

The invention discloses a circuit board protection device used for a child toy automobile. The circuit board protection device comprises a bottom box, a box cover, a locating ring and a fixing column. The bottom box is covered with the box cover. A circuit board containing cavity is formed in the bottom box. Line incoming holes are formed in the lower portion of the bottom box. An annular clamping ring is arranged at the top end of the upper portion of the bottom box. An annular ring is arranged at the lower portion of the box cover. An annular clamping groove of a hollow structure is formed in the annular ring and clamps the annular clamping ring at the top end of the upper portion of the bottom box, so that the box cover is clamped on the bottom box. Heat dissipation holes are formed in the box cover. The circuit board protection device has the beneficial effects of being reasonable in structural design and convenient to connect and fix.

Description

technical field [0001] The present invention relates to an accessory for children's toy car, specifically a circuit board protection device for children's toy car. The children's toy car of the present invention refers to a children's toy car that can be used by children to sit on and drive. A toy car that children under the age of 10 can sit on and drive. Background technique [0002] Some products used for circuit board protection in the existing market have unreasonable structural design, inconvenient connection and fixing, and are not suitable for use on electric strollers.
