Description

M274934 4. Creation Description (1) [Technical Field to which the New Type belongs] This creation relates to a steering control device for electric vehicles. It refers to a control device for electric vehicles that has automatic switching between straight high speed and low steering speed. [Previous technology] 'Press. Generally, electric vehicles use motor-driven driving power. Therefore, driving control is not as easy as that of gasoline-powered vehicles. In addition, users of electric vehicles are fragile and respond slowly. Most people with disabilities or elderly people may not be able to operate properly at the right time to achieve their effectiveness, even if the mechanism is equipped with a brake, especially in steering control. Because electric vehicles are accelerating or driving fast when driving straight, When turning to the left or right-steering operation, it is necessary to slow down properly, otherwise, the vehicle body will turn too fast during steering, resulting in an unbalanced slippage or overturning due to the car's center of gravity deflection, which is an existing electric vehicle. A big hidden danger in driving operation. In addition, there may be improved ones, such as the conventional steering gear shift structure of the electric vehicle shown in the first and second figures, the steering gear shift structure 1 0 0 ′ includes at least a pair of sensing elements 10 and 2 0, It is installed at the appropriate position on the directional control faucet 200 of the front of the electric vehicle and the front fork 300 of the front wheel respectively, and the sensing element 20 includes a pair of contacts 2 1 and 2 2 to generate a relative path ( ON) or disconnection (OFF) control state or electrical signal, and connected to the electric vehicle's operation control circuit through wires 2 3 and 24 respectively. Among them, the electric motor 400 is connected in series with the battery 500. A resistor R is connected in parallel, and the above-mentioned connection of the sensing element 20 is connected.

M274934 4. Creation instructions (2) The wires 2 3 and 24 of points 2 1 and 2 2 are connected in parallel to the two ends of this resistor R. Therefore, in the case where the sensing elements 10 and 20 are in a linear excitation action, The contacts 2 1 and 22 are in the ON state. At this time, the motor 4 0 0 obtains the maximum current (as indicated by the arrow direction in the second figure), and adopts high speed and running to make the electric vehicle at high speed. Of the state. And when the direction control faucet 2 0—when the steering operation is performed to the right or left ~, the relative right or left position shift occurs between the sensing element 10 and 20, as shown in the third figure ( As shown in (A) and (B), the sensing elements 10 and 20 are not in a mutually exciting relationship, so that the contacts 2 1 and 22 of the sensing element 20 are separated from each other, and the circuit is in an OFF state. At this time, the current flowing through the motor 40 is small, so the motor 400 is switched to low speed operation, so that the electric vehicle automatically decelerates when turning to the right or left to avoid excessive speed and production. Accident; however, when the electric vehicle turns to the right or left, because the right and left wheels are driven by the motor 400 at the same time, the speeds of the right and left wheels are the same, and there is also the possibility of overturning or slipping. [New content] The main purpose of the creation of the "electric vehicle steering control device" is to provide an electric vehicle steering control device that can control the rotation speed of the corresponding motor in the electric vehicle and automatically switch the steering of the electric vehicle. The control device makes the electric vehicle operate Convenient and safe driving. In order to achieve the above purpose, the electric vehicle of this creation includes a direction control faucet, a front fork, two pairs of sensing elements and a sensed element of the electric vehicle, among which the sensing element and the sensed element are respectively provided on the direction control faucet. And front fork,

Page 6 M274934 IV. Creation instructions (3) The sensing element and the sensed element act in correspondence with each other. When the direction control faucet and the front fork correspond to the straight position, the sensed element controls the left and right motors of the electric vehicle at high speed. The path signal of the operation; and when the direction control faucet and the front fork are shifted to the left or right, the sensing element generates a disconnection signal that controls the left or right motor of the electric vehicle to decelerate or stop rotating, thereby causing the left wheel or The speed of the right wheel is reduced or stopped to achieve the effect of turning. [Implementation] In order to enable your review committee to work, we have created the "Basic structure of the electric vehicle turning device such as the control device 1 0 0 including 2 ', which is not limited in type and can be used for sensing such as switches. Switching elements. The first embodiment shown in Figures 5 and 6. In this embodiment, a switch is used as an example, that is, when magnetizing, the path (ON) or disconnection of the sensing element 2 0 ′ (J through the wire 2 3 And the operation control circuit of 24. The above two pairs of sensing elements are set on the direction controller of the electric vehicle, and the structure composition of this creation is explained, as well as the overall description as follows: Directional control device ", its electric vehicle steering control As shown in the seventh figure, a pair of reed switches, photoelectric switches, or micro-motions of the electric vehicle steering pair sensing element 10 and the sensed element 20 are shown as normal open (normal open) of the electric vehicle steering control device 100. ) The magnetic hours of the contacts are closed (c 1 〇se), so it includes a pair of contacts to generate a relative OFF) control state or electrical signal, and is connected to the left and right motors on the two sides of the electric vehicle. Piece 1 0 and the sensing element 2 0 ’are installed on the leading 2 0 0 and the front fork 3 0 0

Page 7 M274934 Fourth, the appropriate position of the creative description (4), as shown in the sixth figure, using a fixed 2 1 0 and a fixed frame 3 1 0 to make the sensing element 10 and the sensed element 2 0 ′ By approaching each other, the sensing element 10 and the sensing element 20 ′ can be magnetized correspondingly in a state where the directional control faucet 2 0 0 and the front fork 3 0 0 are both going straight. . The pair of reed switch type sensing element 10 and the sensed element 2 0 ′, because one is the role of an exciting magnet and the other is the role of an excited switch. The difference in the gap length, that is, the position change between the two, adjusts the sensitivity of the sensing action. When the magnetic gap is small, the display sensitivity between the display elements 10 and 20 ′ is low; otherwise, the magnetic When larger, the display sensitivity between the sensing element 10 and the sensed element 20 ′ is relatively better. In the state where the direction control faucet 2 0 0 and the front fork 3 0 0 are straight or the rotation vector is not large and nearly straight, the sensing element 10 and the sensed element 2 0 ′ are linearly corresponding to the control circuit operation of the excitation. Among them, after the left and right motors of the electric vehicle are connected in series with the battery, the wires 2 3 and 24 connected to the contact point of the sensed element 20 ′ are connected in series at both ends of the motor and the battery. When the sensing element 2 0 ′ is in a linear excitation operation, the contacts of the sensing element 2 0 ′ are connected to the ON state. At this time, the left and right motors obtain the maximum current and the left and right wheels adopt high speed. Run to make the electric vehicle run at a high speed. ^ When the direction control faucet 200 is steered to the right or left, the mutual excitation relationship is generated between the sensing element 10 and the sensed element 2 0 ′, resulting in the contact point of the sensed element 2 0 ′. In order to be separated from each other, they are in an OFF state. At this time, the current flowing through the left or right motor of the electric vehicle will be higher than the straight state.

Page 8 M274934 IV. The current when creating the description (5) is small, so the left or right motor is switched to low speed operation, so that the electric vehicle will automatically decelerate or stop working when turning to the right or left to avoid excessive speed. Accidents of skidding or rollover occur; the specific process is as follows: when the direction control faucet 2 0 0 and the front fork 3 0 0 need to be shifted to the left, the position of the sensed element 2 0 ′ and the sensed element 10 shifts accordingly. An OFF signal generated when the contacts of the sensed element 20 'are disengaged from each other, decelerating or stopping the left motor, and turning the right motor to control the electric vehicle to automatically switch to the left; in the direction When the control faucet 2 0 0 and the front fork 3 0 0 need to be turned to the right, the positions of the sensed element 2 0 ′ and the sensed element 10 0 are shifted accordingly, and the contact between the sensed element 2 0 ′ is generated. The signal of open circuit (OFF) or path (0 N) makes the motor on the right decelerate or stop, and controls the electric vehicle to automatically switch to the right. The sensing element on the left side of the steering control device 1 0 • and the sensing element 2 0 'The position is unchanged, and the left motor rotates, which can realize the electric vehicle's Turned; Further, the back main frame provided an electric vehicle after a 'wheel 600 (as shown in FIG. IV), while the rear wheels are lifted 600 make contact with the electric vehicle is traveling straight. The seventh figure shows another embodiment of the electric vehicle steering control device 100. The steering control device 100 of this embodiment also includes a sensing element 10 and a sensed element 20 ′, and the sensing element 20 ′ is externally connected to a wire 23 on an operation control circuit of an electric vehicle and 24, the sensing element 1 0 • It is the sensing element 2 0 ′, which is respectively installed at the appropriate position on the directional control head 2 0 of the electric vehicle and the front fork 3 0 0 of the front wheel, and then the fixing plate 2 1 is used respectively. 0 and the fixed frame 3 1 0 to make the sensing element 10 and the sensed element 2 0 ′ approach each other. However, the sensing element 10 and the sensed element in this embodiment

The contact portion is provided with a fixed block for the elastic contact rod to fall into the spring. On, the fixing plate 2 1 0 also changes in shape with the change of the sensing element 10 and the sensed element 2 0 ′.
