如图 1和图 2所示， 本发明电动滑板包括前轮 1、后轮 2、车架 4和站板 3；其中的前轮 1和后轮 2分别设于车架 4的前后两端；站板 3设于车架 4 ±； 站板 3下还设有驱动后轮 2的电机 5，电机 5的输出轴通过传动带带动后轮 2; 该电动滑板还包括一偏摆转向机构； 该车架 4通过该偏摆转向机构与两前轮 1相连。 该车架 4通过后部的轮轴槽与后轮 2的轮轴相连。  As shown in FIG. 1 and FIG. 2, the electric skateboard of the present invention includes a front wheel 1, a rear wheel 2, a frame 4 and a station board 3; the front wheel 1 and the rear wheel 2 are respectively provided at the front and rear ends of the frame 4; The station board 3 is set on the frame 4 ±; there is a motor 5 driving the rear wheel 2 under the station board 3, and the output shaft of the motor 5 drives the rear wheel 2 through a transmission belt; the electric skateboard also includes a yaw steering mechanism; The frame 4 is connected to the two front wheels 1 through the yaw steering mechanism. The frame 4 is connected to the axle of the rear wheel 2 through a rear axle groove.
该偏摆转向机构包括：  The yaw steering mechanism includes:
两个支撑块 8， 其上设有轮轴， 前轮 1固定在该轮轴上， 如图 4所示， 两个支撑块 8与水平方向呈 25度角向后倾斜；  Two support blocks 8 are provided with a wheel axle, and the front wheel 1 is fixed on the wheel axle. As shown in FIG. 4, the two support blocks 8 are inclined rearward at a 25 degree angle from the horizontal direction;
一杆件 9， 通过螺栓和孔 29固定联接两个支撑块 8;  A rod member 9, two bolts 8 are fixedly connected by bolts and holes 29;
一凸板 10位于杆件 9中部， 其上设有一通孔 12;  A convex plate 10 is located in the middle of the rod 9 and is provided with a through hole 12;
一偏摆杆 11， 穿过该凸板 10上的通孔 12，其两端分别通过孔 30与两个 支撑块 8活动连接； 如图 3所示， 在该通孔 12两侧的偏摆杆 11上分设有弹 簧 13;  A deflection lever 11 passes through the through hole 12 on the convex plate 10, and two ends of the deflection lever 11 are movably connected to the two supporting blocks 8 through holes 30 respectively. As shown in FIG. 3, the deflections on both sides of the through hole 12 A spring 13 is provided on the rod 11;
车架 4前端还设有一安装架 7， 安装架 7上连有一连接件 14; 该连接件 14与该偏摆转向机构相连。  The front end of the frame 4 is also provided with a mounting bracket 7, and a connecting member 14 is connected to the mounting bracket 7; the connecting member 14 is connected to the yaw steering mechanism.
该偏摆转向机构的工作原理是： 当人站在站板 3上， 向右施加重力时， 偏摆杆 11往左边滑动， 前轮 1受到向左的压力， 从而达到向右转的效果。 同 时， 由于右边的弹簧 13在偏摆杆 11的螺帽 31与通孔 12之间被压紧， 所以 当停止向右施加重力时， 弹簧 13反弹， 起到回复滑板方向的作用。如需滑板 向左转时， 亦同理。 The working principle of the yaw steering mechanism is: When a person stands on the station board 3 and applies gravity to the right, The yaw lever 11 slides to the left, and the front wheel 1 receives pressure to the left, thereby achieving the effect of turning to the right. At the same time, because the spring 13 on the right is pressed between the nut 31 of the yaw lever 11 and the through hole 12, when the application of gravity to the right is stopped, the spring 13 rebounds and plays a role of restoring the direction of the slide. The same applies when you need to turn the skateboard to the left.
杆件 9与车架 4之间设有减震弹簧 15。  A damping spring 15 is provided between the lever 9 and the frame 4.
站板 3上设有脚支撑 16。 脚支撑 16的外部可以包覆有弹性套筒。  The platform 3 is provided with a foot support 16. The outside of the foot support 16 may be covered with an elastic sleeve.
车架 4后部的固定位 19上安装有上翘并延伸至后轮 2上方的刹车板 17， 刹车板 17与车架 4间安装有支撑刹车板 17的弹性件 21， 该弹性件 21通过 前后孔位和连接件固定于刹车板 17下方， 刹车板 17为塑件， 弹性件 21为刚 性铁皮， 弹性件 21的形状与刹车板 17的形状相似。当人脚踏在刹车板 17上 时，刹车板 17和弹性件 21被压下， 弹性件 21的下部摩擦后轮 2以阻止其转 动。当人脚抬离刹车板 17后，弹性件 21会自动反弹并将刹车板 17顶回原位。  A brake plate 17 which is tilted upward and extends above the rear wheel 2 is installed on a fixed position 19 at the rear of the frame 4. An elastic member 21 for supporting the brake plate 17 is installed between the brake plate 17 and the frame 4. The front and rear holes and the connecting member are fixed below the brake plate 17. The brake plate 17 is a plastic piece, and the elastic member 21 is a rigid iron sheet. The shape of the elastic member 21 is similar to that of the brake plate 17. When a person steps on the brake plate 17, the brake plate 17 and the elastic member 21 are depressed, and the lower portion of the elastic member 21 rubs the rear wheel 2 to prevent it from rotating. When the human foot lifts off the brake plate 17, the elastic member 21 will automatically rebound and push the brake plate 17 back to the original position.
本发明电动滑板还包括一控制器 18， 其位于站板 3下的车架 4上。 控制 器 18可以采用 LB27D型控制器。 控制器 18与电动滑板的电机 5、 蓄电池 6 和电源开关相连， 起着连接整套电路、 调整速度、 保护蓄电池 6和电机 5的 作用， 其工作原理是通过调整脉冲宽度使电机 5转速从零至最大， 通过限制 电流不超过电机 5最大负荷来保护电机 5， 当蓄电池 6电压低于一定值时， 通过电压保护装置使电机 5停止运转， 以达到保护蓄电池 6的目的。  The electric skateboard of the present invention further includes a controller 18 which is located on the frame 4 under the station board 3. The controller 18 may be an LB27D type controller. The controller 18 is connected to the motor 5, the battery 6 and the power switch of the electric skateboard, and plays a role of connecting the entire circuit, adjusting the speed, and protecting the battery 6 and the motor 5. Its working principle is to adjust the speed of the motor 5 from zero to 0 by adjusting the pulse width The maximum value is to protect the motor 5 by limiting the current not exceeding the maximum load of the motor 5. When the voltage of the battery 6 is lower than a certain value, the motor 5 is stopped by a voltage protection device to protect the battery 6.
本发明电动滑板还包括蓄电池 6， 其位于站板 3下的车架 4上， 并与控 制器 18和电机 5相连。  The electric skateboard of the present invention further includes a battery 6, which is located on the frame 4 under the station board 3 and is connected to the controller 18 and the motor 5.
本发明电动滑板的另一个实施例中， 车架 4前端的安装架 7上还可以设 有一可拆卸的扶手。 使用者可以根据需要安装使用该扶手。 该扶手包括手柄 24、 高度调节锁扣 25、 扶手立杆 26和两边折向下方的底板， 该底板顶面和 侧面开有安装孔。 安装该扶手时， 只需使用螺栓 28和销栓 27等连接件通过 该底板上的安装孔以及安装架 7 上的对应的安装孔即可将扶手安装于滑板 上， 反之， 即可将该扶手卸下。 工业实用性  In another embodiment of the electric skateboard of the present invention, the mounting bracket 7 at the front end of the frame 4 may further be provided with a detachable armrest. The user can install and use the armrest as required. The armrest includes a handle 24, a height adjustment lock 25, an armrest post 26, and a bottom plate folded down on both sides. The bottom surface of the bottom plate is provided with mounting holes. When installing the armrest, the armrest can be mounted on the slide board only by using the connecting members such as bolts 28 and bolts 27 through the mounting holes on the bottom plate and the corresponding mounting holes on the mounting bracket 7, otherwise, the armrest can be installed. Remove. Industrial applicability
