Abstract

A running wheel. A circuit board (5) of a remote control (200) of the running wheel is fixed within a housing of the remote control (200) via a screw. Because the circuit board (5) of the remote control (200) of the running wheel is fixed within the housing of the remote control (200) via the screw, and the screw is firmly fixed, the circuit board (5) can be firmly fixed within the housing of the remote control (200) and does not move or sway easily, thus ensuring that buttons on the remote control (200) can fit normally with the circuit board (5); also, fixing with the screw allows for easy disassembly, thus facilitating inspection when a fault arises.

Description

a mad round

[Technical Field]

The present invention relates to the field of toys and, more particularly, to a mad wheel. 【Background technique】

Some toy cars such as toy cars and crazy running wheels generally have two types of automatic control and wireless control. The wireless control is generally controlled by an infrared remote control. The remote control of a toy car such as a toy car or a mad running wheel has a built-in battery for power supply. Once the battery in the remote control is used up, it needs to be replaced, so you need to replace the battery frequently, which is more expensive.

I designed a crazy running wheel, including a vehicle body and a remote controller for controlling the vehicle body. The remote controller includes a USB connector fixed in a placing box, a casing provided with a sliding slot for sliding the placing box, and A control member for controlling the sliding of the placement box. The circuit board of the remote controller is fixed on the upper part of the usb connector, and the housing is provided with a support plate for supporting the circuit board. The housing includes an upper case and a lower case fixed by screws, and the circuit board is fixed by fixing the upper case and the lower case. . This program is not public. However, the circuit board fixed by the upper and lower casings is not strong enough, and it is easy to contact poorly when the keys for controlling the vehicle body are matched on the circuit board and the remote controller.

Connecting the first support plate and the lower case screw hole column not only increases the strength of the lower case screw hole column, but also greatly increases the strength of the support plate.

Preferably, the top of the first supporting plate is provided with a limiting post, and the circuit board is provided with a limiting hole for placing the limiting post. The limiting hole on the circuit board cooperates with the limiting post on the housing, and the circuit board is used to limit the position before the circuit board is fixed, thereby preventing the circuit board from moving or shaking, thereby facilitating the screwing, thereby enabling The fixing is firmer.

Preferably, the first supporting plate is located at one side of one end of the housing, and the supporting plate further comprises a second supporting plate disposed on the other side of one end of the housing. By providing two support plates on both sides of one end of the housing for supporting the circuit board, the support effect is good, the circuit board is placed stably, and the circuit board is conveniently fixed.

Preferably, a reinforcing plate is disposed on the side wall of the screw hole column. Set the stiffener to increase the strength of the screw post.

Preferably, a top of the reinforcing plate is provided with a limiting post, and the circuit board is provided with a limiting hole for placing the limiting post. There is a certain distance between the limiting post and the side wall of the screw hole post, so that the screw and the screw hole and the screw hole post are conveniently fixed. Before the screw is fixed, the limiting post is first inserted into the limiting hole on the circuit board. In this way, the board is first limited, which not only makes it difficult to move, but also facilitates screw fixing. This also makes the screws more secure.

The invention fixes the circuit board of the remote controller of the mad wheel to the casing of the remote controller by screws The screws are fixed firmly, so that the circuit board can be firmly fixed in the casing of the remote control, making it difficult to move and shake, ensuring that the keys on the remote control can be properly matched with the circuit board; and the screws are easily removed, and problems occur. It can be taken apart for inspection.
