[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 The control member for controlling the sliding of the placement box and the button for controlling the vehicle body are fixed to the housing by screws. This program is not public. Since the button is often pressed, the screw may be loosened, which may affect the stability of the button fixing.

[Summary of the Invention]

The technical problem to be solved by the present invention is to provide a mad running wheel with a fixed button on the remote controller.

The object of the present invention is achieved by the following technical solutions: a mad wheel, the control button on the remote control of the mad wheel is fixed on a button frame provided with a fixing hole, and the casing of the remote controller is provided with And a fixing column inserted into the fixing hole.

Preferably, after the fixing post is inserted into the fixing hole, the top of the fixing column is hot-melted, and the top of the heat-fixed fixing column is larger than the fixing hole. The fuser is securely fastened and stable to limit the button holder to the fixed post.

Preferably, there are two fixing posts, which are respectively located at two sides of the button frame. This is to set the specific structure and position of the fixed column, and set two opposite fixed columns; the corresponding fixed holes are also two. The fixing post and the fixing hole cooperate to make the limit and fixing effect on the button frame better.

Preferably, the fixing column has a cylindrical structure. The fixed column of the cylindrical structure has a single structure and is easy to produce. The corresponding fixed hole structure is a circular structure, and the fixing hole and the fixed column are matched to facilitate the fixing.

Preferably, after the fixing post is inserted into the fixing hole, the fixing post and the key frame are fixed together by heat fusion. The hot melt fixes the fixing column and the key frame together, and the heat fusion is firmly fixed and is not easy to loose.

Preferably, after the fixing post is inserted into the fixing hole, the button frame is fixed on the fixing post by glue bonding. The glue is firmly bonded and easy to produce.

Preferably, the button comprises a forward, backward, left turn, right turn and stop button. This is the specific button on the remote control that controls the mad wheel body. These buttons make it easy to control the body of the mad wheel.

Preferably, a through hole edge of the housing of the remote controller for placing the control button is provided with a limiting flange for limiting the control key. Setting the limit flange prevents the button from coming off the button holder, which prevents the button from being damaged and causing poor contact.

【detailed description】

The invention will now be further described with reference to the drawings and preferred embodiments.

The invention discloses a mad running wheel. As shown in FIG. 1 to FIG. 7 , a vehicle body 100 and a remote controller 200 for controlling the vehicle body 100 are provided. The control button 7 on the remote controller 200 is fixed to the fixing hole 72. On the button frame 71, the housing of the remote controller 200 is provided with a fixing post 11 for inserting the fixing hole 72. In the present invention, the control button 7 on the remote controller 200 of the mad wheel is fixed on the button frame 71. The button frame 71 is provided with a fixing hole 72. The housing of the remote controller 200 is provided with a fixing column 11 matched with the fixing hole 72. Inserting the fixing post 11 into the fixing hole 72 fixes the key frame 71 together with the control member 7 on the housing; by the cooperation of the fixing post 11 and the fixing hole 71, the screw loosening does not occur when the control member 7 is pressed. The situation is, in turn, firm and stable.

As shown in FIG. 1 and FIG. 2, the remote end of the remote control 200 is provided with a USB connector 4 for connecting to a computer. The USB connector 4 is fixed inside the casing through a placement box 3, and the USB connector 4 is glued by glue.
