Description

Circuit board protection device for children's toy car and using method thereof

technical field

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

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. Generally, screws are used to fix the protection device, which is inconvenient to disassemble. The fixing of the toy car is also inconvenient.

Contents of the invention

The invention provides a circuit board protection device for a children's toy car.

The purpose of the present invention is to solve the problems of unreasonable structural design, inconvenient connection and fixation, and unsuitability for use on electric baby carriages in some existing products used for circuit board protection, that is, what this patent solves is toys in the technical field The circuit board of the car, the circuit board refers to the circuit assembly of a toy car, it can also be the main controller board, or other circuit boards on the toy car, as long as the circuit board needs external protection can be used.

The technical solution adopted by the present invention to solve the technical problem is: a circuit board protection device for children's toy cars, including a bottom box, a box cover, a positioning ring, and a fixing post, the box cover is covered on the bottom box, and the The inside of the bottom box is a circuit board placement cavity, the bottom of the bottom box is provided with an inlet hole, the upper top of the bottom box is provided with a ring collar, the bottom of the box cover is provided with a ring ring, and the ring The ring is provided with a ring-shaped slot with a hollow structure, and the ring-shaped slot is stuck on the ring-shaped ring on the upper top of the bottom box, so that the box cover is stuck on the bottom box, and the box cover is provided with cooling holes.

There are three wire inlet holes, namely the first wire inlet hole, the second wire inlet hole and the third wire inlet hole. Narrow and wide structure.

There are three heat dissipation holes, namely the first heat dissipation hole, the second heat dissipation hole and the third heat dissipation hole.

The bottom box and the annular collar are integrally formed.

The interior of the positioning ring is a hollow structure, and the transverse diameter of the hollow structure inside the positioning ring is a trumpet structure with a large top and a small bottom, that is, an inverted trapezoidal structure that gradually becomes smaller from top to bottom.

One side of the positioning ring is provided with an inner screw hole in the positioning ring, and the two ends of the fixing column are provided with external threads, which are respectively the first external thread and the second external thread, and the fixed column passes through the first external thread. Cooperate with the inner screw hole of the positioning ring to be fixed on the positioning ring, and the second external thread at the lower part of the fixing column is fixed to the corresponding position of the children's toy car.

The inner wall of the hollow structure is provided with a first concave-convex structure.

A second concave-convex structure is provided on the inner wall of the annular locking groove.

The bottom box, the box cover, the positioning ring and the fixing column are made of non-metallic materials.

The bottom box, the box cover, the positioning ring and the fixing column are made of plastic materials.

A method for using a circuit board protection device for a children's toy car, which is characterized in that the required circuit board is placed in the circuit board placement cavity, and then connected to the corresponding mechanism of the toy car through the wire inlet hole set at the bottom, and the connection is completed. Finally, as long as the ring slot of the box cover is stuck on the ring ring at the top of the bottom box, the protection device is combined, and then the protection device is placed in the positioning ring, because the positioning ring is fixed on the children's toy through the fixing column. It is in the corresponding position of the car, so the protection device does not need any external device to fix it, and it is easy to disassemble and use. If you need to overhaul or replace the circuit board, just take off the box cover that is stuck on the ring collar on the upper top of the bottom box. Can.

The invention has the following advantages: 1. The structure is simple, as long as the annular clip groove of the box cover is clamped on the annular collar at the upper top of the bottom box, the combination can be carried out; 2, heat dissipation holes are provided, and the heat dissipation effect is good; The wire inlet, instead of being set on the side arm of the bottom box, increases the strength of the bottom box, because the bottom box is connected to the corresponding position of the stroller frame/body in the children's toy car through the positioning ring, and even if it is opened in the bottom box side arm, then the wire inlet hole will be blocked by the positioning ring, which is hindered when we wire the electric car, and the wiring is inconvenient; 3. It is easy for users to use. Children's toy cars are for children to play. Due to the necessary safety settings, For the sake of safety, some circuit breakers will be installed under certain circumstances. Therefore, when consumers use it in the later stage, they will need to open the circuit board protection device many times to connect the circuit, etc.; according to different incoming and outgoing directions. We choose to set the wire inlet holes in all aspects of different junction boxes. We set the wire inlet holes at the bottom to increase the strength of the bottom box. Because the present invention designs the positioning ring as a trumpet structure with a large top and a small bottom, it is relatively easy to put it in, and there is also a first concave-convex structure. Due to the effect of friction, the bottom box is not easy to shake in the hollow structure.

At the same time, a second concave-convex structure is provided on the inner wall of the annular clamping groove. After the annular collar is inserted into the annular card slot, the connection is more precise, and it is not easy to loosen and fall off.
