Problems solved by technology
[0007] Therefore, there are some problems in the aforementioned electric vehicles for children in the past, such as: the emergency parking of the vehicle or the excessive braking distance lead to the occurrence of safety accidents
[0008] That is to say, when the vehicle is running at a low speed, when the braking device exerts its braking effect, the vehicle is still stopped in an emergency, and the occupant leans forward instantly, which in turn leads to the occurrence of safety accidents such as spinal injuries or contusions; When the vehicle is running at high speed, when the braking device exerts its braking effect, the braking distance is still too long, resulting in hitting obstacles such as walls
[0009] In particular, the main users of the above-mentioned electric vehicles are children with underdeveloped physical ability and unskilled driving operation ability. The risk of safety accidents such as collision with obstacles caused by emergency parking or incomplete braking of the vehicle is undoubtedly greater

Embodiment Construction
[0029] The following will refer to the attached Figure 1 to Figure 7 Related preferred embodiments of the control device and control method of the electric vehicle for children of the present invention will be described.
[0030] as attached figure 1 As shown, the electric vehicle for children according to the embodiment of the present invention is characterized in that it is roughly composed of a driving unit 100 , a speed sensor 200 and a control unit 300 .
[0031] Hereinafter, this will be further described in detail according to its different structures.
[0032] First, the drive unit 100 is a series of structures that receive power from the battery 10 and are driven by a drive motor 110 and a speed reducer 120 .
[0033] At this time, the driving motor 110 is constituted by a DC motor that realizes deceleration and acceleration under the action of adding and subtracting voltage (or current).
[0034] In addition, the speed reducer 120 is a transmission device that de...

The invention relates to an electric vehicle for children and a braking control method thereof. Differential braking control is achieved according to running conditions of the electric vehicle for children, and then the electric vehicle for children and the braking control method of the electric vehicle avoid children safety accidents caused by emergency braking and children safety accidents caused by slow braking. The braking control method of the electric vehicle for children includes: a speed sensing phase that a speed sensor senses vehicle running speed and a control phase that whether braking control or accelerating control is executed is judged according to whether the sensed running speed and braking signals or running signals are disconnected to perform control. According to the electric vehicle for children and the braking control method of the electric vehicle, even if passengers do not implement other braking operation, running speed of a corresponding vehicle can be controlled within a safety speed range, and therefore dangerous conditions can be avoided in advance.
Description
technical field [0001] The present invention relates to an electric vehicle for children, and more particularly relates to a method of realizing differential braking control according to the driving conditions of the electric vehicle for children, so as to prevent the occurrence of child safety accidents caused by emergency braking and those caused by slow braking. A new form of children's electric vehicle and its braking control method for the occurrence of child safety accidents. Background technique [0002] Generally, an electric vehicle for children is a toy that is driven by a battery and a motor and is driven by children directly operating the steering wheel. [0003] Of course, the above-mentioned electric vehicle for children can additionally be equipped with a wireless control device, so that the guardian can also control the operation of the electric vehicle through wireless control, thereby ensuring the safety of children who lack control over external obstacles....
