本发明的速度踏力传感装置中, 当使用者用力脚踏使曲柄转动, 啮合在牙盘上 的链条上半部分产生张紧力, 该力使啮合链条的过渡链轮产生逆吋针方向的力 矩, 使受力架转动; 由于受力架转动使压缩弹簧压缩变形, 其变形量与链条张 紧力成正比; 而压缩弹簧压缩变形量与踏力测试磁钢的位移量相等, 所以链条 张紧力与线性霍尔传感器检测的变化值成正比, 这使得压缩弹簧压缩变形量可 以在线性霍尔传感器中显示出来。 由于链条的张紧力直接反映出了脚踏力的大 小, 所以通过线性霍尔传感器和设置的踏力测试磁钢可以直接的反应脚踏力的 大小, 用以进行控制电动助力的增减。 而过渡链轮端面设置了速度测试磁钢, 通过速度测试磁钢在链轮运转吋与开关霍尔传感器的感应有无, 可以了解过渡 链轮的转速, 从而得到自行车的运行速度; 这样就可以从脚踏力和骑行速度两 方面进行考虑来控制电动自行车的电动助力。 In the speed pedaling sensing device of the present invention, when the user turns the crank with a force pedal, the upper half of the chain engaged with the crankset generates a tensioning force which causes the transition sprocket of the engaging chain to generate a reverse needle direction. The torque causes the force frame to rotate; the compression spring compresses and deforms due to the rotation of the force frame, and the deformation amount is proportional to the chain tension; and the compression spring compression deformation is equal to the displacement of the pedal force test magnet, so the chain tension is tight. The force is proportional to the change detected by the linear Hall sensor, which allows the compression spring compression deformation to be displayed in the linear Hall sensor. Since the tension of the chain directly reflects the size of the pedaling force, the linear Hall sensor and the set pedaling force test magnet can directly reflect the magnitude of the pedaling force to control the increase and decrease of the electric assist. The speed test magnet is set on the end face of the transition sprocket. Through the speed test, the magnet can be used in the sprocket operation and the sensor of the switch Hall sensor to know the rotation speed of the transition sprocket, so as to obtain the running speed of the bicycle; The electric power of the electric bicycle is controlled by considering both the pedaling force and the riding speed.

The pedaling test magnet 321 is matched with induction. The end of the second sprocket 112 is coaxially disposed with a speed test magnet 32 2 , and the Hall seat 31 is adjacent to the end face of the second sprocket and is coupled with the speed test magnet 322.
[32] 弹性部件为与霍尔座固定的弹性片, 弹性片夹持设置固定块 33, 固定块一端设 置踏力测试磁钢 321, 另一端外侧设置压缩弹簧 34和钢珠 35与定位座 5连接。 盖 板为三角形盖板, 受力架与电动自行车牙盘间设置定位座 5; 定位座与受力架的 双层盖板端部销接, 且受力架下端设置调节螺栓 15连接定位座, 调节螺栓上设 置复位弹簧 16。 [32] The elastic member is an elastic piece fixed to the Hall seat, and the elastic piece is provided with a fixing block 33. The one end of the fixing block is provided with a pedaling test magnet 321, and the other end is provided with a compression spring 34 and a steel ball 35 connected to the positioning seat 5. The cover plate is a triangular cover plate, and a positioning seat 5 is arranged between the force frame and the electric bicycle tooth plate; the positioning seat is pinned to the end of the double-layer cover plate of the force frame, and the adjusting bolt 15 is arranged at the lower end of the force frame to connect the positioning seat. A return spring 16 is provided on the adjusting bolt.
[33] 电动自行车牙盘固定在联接轴 6上, 联接轴 6上套设定位座 5, 定位座 5与联接轴 6间设置轴承。 定位座 5上设置支撑架 51与电动自行车固定; 电动自行车牙盘与 定位座 5间设置与定位座固定的压板 52, 压板 52与定位座 5配合轴向限位轴承。
受力架盖板间过渡链轮与定位过渡链轮的销轴间设置轴承; 电动自行车牙盘与 过渡链轮处于同一齿中心面上; 联接轴 6两端连接人力驱动的曲柄 7。 [33] The electric bicycle crankset is fixed on the coupling shaft 6, and the coupling shaft 6 is sleeved on the setting seat 5, and a bearing is arranged between the positioning seat 5 and the coupling shaft 6. The positioning base 5 is provided with a support frame 51 and an electric bicycle. The electric bicycle sprocket wheel and the positioning base 5 are provided with a pressing plate 52 fixed to the positioning seat. The pressing plate 52 and the positioning seat 5 cooperate with the axial limiting bearing. The bearing between the transition sprocket between the force-receiving cover and the pin of the positioning transition sprocket is disposed; the electric bicycle sprocket wheel and the transition sprocket are on the same tooth center surface; the two ends of the coupling shaft 6 are connected with the human-driven crank 7.
[34] 受力架 1与定位座 5间可相互运动。 受力架 1与定位座 5端部销接, 定位座通过支 撑架 51与电动自行车固定, 且由于支撑架 51、 联接轴、 销轴三点确定, 使定位 座 5在电动自行车运行吋不会发生偏转。 这样的三点定位也使得与定位座销接的 受力架不会偏转, 从而可以确保过渡链轮的受力和速度不会因偏转产生误差。 安装吋, 联接轴上套设轴承, 所述定位座与轴承外圏固定, 而轴承内圏与联接 轴固定; 这样牙盘、 曲柄以及连接在曲柄末端的脚踏同步运动吋, 联接轴不会 影响定位座, 另外设计压板与定位座固定使其轴向限位轴承, 使牙盘与定位座 产生相对转动的同吋, 其轴向距离保持不变。 [34] The force frame 1 and the positioning seat 5 can move relative to each other. The force frame 1 is pinned to the end of the positioning base 5, and the positioning seat is fixed to the electric bicycle through the support frame 51, and since the support frame 51, the coupling shaft and the pin shaft are determined at three points, the positioning seat 5 is not operated on the electric bicycle. Deflection occurs. Such a three-point positioning also causes the force frame attached to the positioning pin to be deflected, thereby ensuring that the force and speed of the transition sprocket are not disturbed by the deflection. Mounting 吋, the coupling shaft is sleeved with a bearing, the positioning seat is fixed with the outer casing of the bearing, and the inner cymbal of the bearing is fixed with the coupling shaft; thus the sprocket wheel, the crank and the pedal connected to the end of the crank are synchronously moved, the coupling shaft does not Influencing the positioning seat, the designing of the pressing plate and the positioning seat is fixed to the axial limiting bearing, so that the tooth plate and the positioning seat generate relative rotation, and the axial distance remains unchanged.
[35] 为了使牙盘的齿中心面始终与过渡链轮的齿中心面保持在同一平面上, 除了通 过支撑架 51、 联接轴、 销轴使定位座、 受力架保持轴向固定的同吋, 将受力架 设计成双层盖板结构, 过渡链轮包括第一链轮 111和第二链轮 112设置在双层盖 板之间, 并使其齿中心面与牙盘齿中心面水平。 更具体的, 双层盖板间设置链 轮固定轴, 所述过渡链轮与链轮固定轴间设置轴承, 所述过渡链轮与轴承外圏 固定, 链轮固定轴与轴承内圏固定连接; 这样保证了过渡链轮与受力架的相对 转动, 也使链轮固定轴与过渡链轮间轴向距离保持不变。 [35] In order to keep the tooth center plane of the crankset in the same plane as the tooth center plane of the transition sprocket, except that the positioning bracket and the bearing frame are axially fixed by the support frame 51, the coupling shaft and the pin shaft吋, the force frame is designed as a double-layer cover structure, and the transition sprocket includes a first sprocket 111 and a second sprocket 112 disposed between the double-layer cover plates, and has a tooth center surface and a tooth center surface Level. More specifically, a sprocket fixing shaft is disposed between the double-layer cover plates, and a bearing is disposed between the transition sprocket and the fixed wheel of the sprocket, the transition sprocket is fixed with the outer casing of the bearing, and the fixed shaft of the sprocket is fixedly connected with the inner ring of the bearing This ensures the relative rotation of the transition sprocket and the force frame, and also keeps the axial distance between the sprocket fixed shaft and the transition sprocket unchanged.
[36] 另外, 为了使受力架在受力转动后复位在受力架的下端与定位座间设置调节螺 栓, 设置调节螺栓一方面可以改变两过渡链轮的不同高度位置, 使其满足骑行 者个体助力需要; 另一方面, 在调节螺栓上设置复位弹簧使链轮不受力吋受力 架可以进行复位, 以方便一般无需电动助力情况下的骑行运动。 [36] In addition, in order to reset the force frame after the force is rotated, the adjusting bolt is arranged between the lower end of the force frame and the positioning seat, and the adjusting bolt can be set on the one hand to change the different height positions of the two transition sprocket, so as to satisfy the riding. On the other hand, the reset spring is arranged on the adjusting bolt so that the sprocket can be reset without being subjected to the force rig, so as to facilitate the riding motion without the electric assist.
[37] 本装置的传感器中设计安装了霍尔座 31和与霍尔座 31配合感应的磁钢座 32, 其 中霍尔座包括线性霍尔传感器和开关霍尔传感器; 而磁钢座包括踏力测试磁钢 和速度测试磁钢。 其中速度测试磁钢分布在过渡链轮的端面上, 具体的说同轴 设置在第二链轮 112端面上; 这里速度测试磁钢可以为多个, 可以一个; 当过渡 链轮转动吋, 速度测试磁钢同步转动, 其与开关霍尔传感器感应启闭。 本发明 极为突出的设计而踏力测试磁钢的应变设计。 具体的, 所述踏力测试磁钢与线 性霍尔传感器对应, 且固定在固定块上, 所述固定块两端通过弹性部件如弹性 片与霍尔座连接, 且所述固定块的一端外侧分别设置压缩弹簧和钢珠与定位座 连接; 由于定位座在受力架受力转动吋并不发生转动, 所以当受力架转动运动 产生吋, 定位座推动钢珠移动, 压缩弹簧压缩; 压缩弹簧的压缩使固定在固定 块上的磁钢发生位移从而引起线性霍尔传感器的感应。 [37] The Hall sensor 31 and the magnet seat 32 inductively coupled with the Hall seat 31 are designed and installed in the sensor of the device, wherein the Hall block includes a linear Hall sensor and a switch Hall sensor; and the magnet seat includes the pedal force Test magnetic steel and speed test magnetic steel. Wherein the speed test magnet is distributed on the end face of the transition sprocket, specifically coaxially disposed on the end face of the second sprocket 112; where the speed test magnet may be multiple, one may be; when the transition sprocket is rotated, the speed The synchronous rotation of the magnetic steel is tested, which is inductively opened and closed with the switch Hall sensor. The extremely prominent design of the present invention is to test the strain design of the magnetic steel. Specifically, the pedaling test magnetic steel corresponds to the linear Hall sensor and is fixed on the fixed block, and the two ends of the fixing block are connected to the Hall by an elastic member, such as an elastic piece, and the outer side of the fixed block is respectively The compression spring and the steel ball are arranged to be connected with the positioning seat; since the positioning seat does not rotate after being pressed by the force frame, when the rotating motion of the force frame generates a flaw, the positioning seat pushes the steel ball to move, and the compression spring compresses; the compression of the compression spring The magnetic steel fixed on the fixed block is displaced to cause induction of the linear Hall sensor.
[38] 为了更为具体的说明线性霍尔传感器检测踏力的原理, 先阐述一下本实施例装 置在骑行吋的受力情况。 当脚踏使联接轴两端固定的曲柄转动吋, 所述曲柄通 过联接轴带动牙盘转动, 再由牙盘通过链条链传动过渡链轮; 由于链条的上半 部分与第一链轮的下端、 第二链轮的上端啮合, 链条并非处于一条直线上, 这 样在曲柄产生的力的作用下, 链条的上半部分产生相应的张紧力, 所述张紧力 使得第一链轮、 第二链轮产生方向相反的两个力, 该力使得受力架具有产生绕
销轴向下旋转的趋势, 而且该力与链条的张紧力相等; 当受力架向下转动吋, 固定踏力测试磁钢的固定块在不动的定位座的作用下向上运动, 驱使压缩弹簧 压缩变形, 踏力测试磁钢产生位移。 [38] In order to explain more specifically the principle of detecting the pedaling force by the linear Hall sensor, the stress of the device in this embodiment is explained first. When the pedal rotates the crank fixed at both ends of the coupling shaft, the crank drives the crankshaft to rotate through the coupling shaft, and then the chain pulley drives the transition sprocket; the upper half of the chain and the lower end of the first sprocket The upper end of the second sprocket is engaged, and the chain is not in a straight line, so that under the force generated by the crank, the upper half of the chain generates a corresponding tension, the tensioning force makes the first sprocket, the first The two sprocket wheels produce two forces in opposite directions, which forces the force frame to produce a winding The tendency of the pin to rotate downward in the axial direction, and the force is equal to the tension of the chain; when the force frame is rotated downward, the fixed block of the fixed pedal test magnetic steel moves upward under the action of the fixed positioning seat to drive the compression The spring is compressed and deformed, and the pedaling force tests the displacement of the magnet.
[39] 本装置中线性霍尔传感器和踏力测试磁钢检测踏力的过程如下: 线性霍尔传感 器安装在霍尔座上, 其外侧设置踏力测试磁钢, 霍尔座通过弹性部件连接固定 踏力测试磁钢的固定块。 本装置中釆用的踏力测试磁钢为单块磁钢, 该磁钢产 生磁场, 它是永磁体, 用树脂胶固定在固定块上。 链条的张紧力迫使受力架发 生位移, 从而固定块发生运动, 而固定在固定块上的踏力测试磁钢发生相同的 位移量, 这种位移为线性霍尔传感器捕获并传递给电动控制器。 [39] The linear Hall sensor and the pedal force test magnet in this device detect the pedaling force as follows: The linear Hall sensor is mounted on the Hall seat, the outside of which is set with the pedaling test magnet, and the Hall seat is connected by the elastic member to fix the pedaling force test. Fixed block of magnetic steel. The pedaling force test magnet used in the device is a single piece of magnetic steel, which generates a magnetic field, which is a permanent magnet and is fixed on the fixed block with a resin glue. The tension of the chain forces the force frame to shift, so that the fixed block moves, and the pedaling test magnet fixed on the fixed block generates the same displacement, which is captured by the linear Hall sensor and transmitted to the electric controller. .
[40] 本实施例中速度测试磁钢设置在过渡链轮的端面上; 速度测试磁钢可以为一个 , 可以为多个; 当链条上半部分啮合过渡链轮传动吋, 过渡链轮转动带动速度 测试磁钢同步转动。 本实施例中开关霍尔传感器和速度测试磁钢检测速度的过 程如下: [40] In this embodiment, the speed test magnet is disposed on the end face of the transition sprocket; the speed test magnet may be one, which may be multiple; when the upper part of the chain engages the transition sprocket drive, the transition sprocket rotates to drive The speed test magnet rotates synchronously. The process of detecting the speed of the switch Hall sensor and the speed test magnet in this embodiment is as follows:
[41] 由于过渡链轮的转速与电动自行车的骑行速度成正比, 而过渡链轮与速度测试 磁钢同轴设置, 过渡链轮的转速可以通过检测速度测试磁钢的转速来实现。 本 实施例中霍尔座包括开关霍尔传感器, 开关霍尔传感器固定设置在过渡链轮 ( 本实施例中在第二链轮) 的端面附近, 且保证速度测试磁钢与开关霍尔传感器 距离最近吋, 开关霍尔传感器产生一个信号输出。 当过渡链轮上仅设置一个速 度测试磁钢吋, 开关霍尔传感器的信号输出频率的快慢直接反映出过渡链轮的 速度变化。 当然, 这种开关检测方式也可以釆用如光电、 词典感应等方式来实 现。 [41] Since the rotational speed of the transition sprocket is proportional to the riding speed of the electric bicycle, and the transition sprocket is coaxially set with the speed test magnetic steel, the rotational speed of the transition sprocket can be realized by detecting the rotational speed of the magnetic steel by the detecting speed. In this embodiment, the Hall block includes a switch Hall sensor, and the switch Hall sensor is fixedly disposed near the end face of the transition sprocket (in the embodiment, the second sprocket), and the distance between the speed test magnet and the switch Hall sensor is ensured. Recently, the switch Hall sensor produces a signal output. When only one speed test magnet is set on the transition sprocket, the speed of the signal output frequency of the switch Hall sensor directly reflects the speed change of the transition sprocket. Of course, this type of switch detection can also be implemented by means of photoelectricity, dictionary sensing, and the like.
[42] 本实施例中在定位座上设置支撑架 51, 所述支撑架可以与定位座螺纹连接固定 , 通过支撑架 51的限位使得定位座不致于产生跳动, 造成速度踏力传感装置的 检测误差; 当然, 将支撑架 51与定位座间设计成螺纹连接, 可以方便定位座的 定位安装; 也可以进行定位座的高度调节。 [42] In this embodiment, a support frame 51 is disposed on the positioning seat, and the support frame can be screwed and fixed to the positioning seat. The position of the support frame 51 prevents the positioning seat from generating a jump, thereby causing the speed pedaling device. Detection error; Of course, the support frame 51 and the positioning seat are designed to be screwed, which can facilitate the positioning and positioning of the positioning seat; and the height adjustment of the positioning seat can also be performed.
[43] 将本实施例提供的速度踏力传感装置检测到的速度信息和踏力变化信息通过相 应控制电路来完成对电动助力系统的驱动马达控制, 就可以实现电动自行车的 智能化的人力电力比例分配。 [43] The speed information and the pedaling force change information detected by the speed pedaling force sensing device provided by the embodiment are controlled by the corresponding control circuit to complete the driving motor control of the electric power assisting system, thereby realizing the intelligent human power ratio of the electric bicycle. distribution.
