New description: [New technical field] This creation is about a crank torque sensing device, especially one that can convert the force applied to the crank into an angular displacement and generate a torque sensing signal for auxiliary electric Sensing technology based on force output. [Prior Art] According to the fact that the power-assisted bicycle is light and flexible, many of the world's cannabis are actively being developed. The torque sensing device required for the electric assisted bicycle plays a role as a fine key. With the rise of environmental awareness, electric-assisted bicycles are gradually favored by consumers in the market. They not only enjoy the riding test of bicycles, but also the requirements of power. Because of the thief exhaust, in the short-distance commuting of emerging cities, there are also Gradually replacing the trend of fuel locomotives. Most of the electric assist bicycles drive the crank H through the human power. When the driving force reaches the preset value, the motor can be started to turn the auxiliary power to drive the electric bicycle to operate, thereby achieving the purpose of riding and labor saving. At present, there are many torsion forces, such as torsion sensing, etc.). Vehicles that are cut by electric power wires (such as bicycles, wheelchairs or scooters) have different dynamic mechanical structures. The design will also be different because of the technology of the power machine. Using torque to sense its structure Π 2 胄) 胄 F wire bicycle torque ❹ 』 』 patent, its structure is her paste, _ she, plum _ strain gauge, M430429 for direct measurement of the force of the sleeve to transform into a strain, The strain signal is transmitted by the strain sensor to sense the crank torque state. The Republic of China No. M417321 "Motorcycle Power Control Device" patent, which includes the sleeve, the driven member, the driven member, the shape variable of the drive member, and the torque calculation unit, the torque calculation unit The deformation (4) produced when the follower is rotated is used to achieve the purpose of torque sensing. It mainly measures the deformation of the follower and the effect of sensing the torque. The patent of the Republic of China No. M410012 "Crankshaft Combination with Torque Sensing Function" includes a crank unit, a surface acoustic wave unit, a strain gauge and a working unit. The crank unit includes a crank shaft and a connecting ring. The surface acoustic wave unit is configured to generate a first electric wave and a second electric wave. The strain gauge is electrically connected to form a loop and affect the second electric wave. The working unit calculates the torque value based on the difference between the first electric wave and the second electric wave. It is mainly a surface acoustic wave unit with a strain gauge and a torque sensing effect, but its structure is complicated and the cost is high. The patent of the "Crank Torque Sensing Device" of the No. 396253 of the Republic of China, mainly relies on the reaction force of the large toothed disc to drive the chain when pedaling the pedal, and generates a pulling force at the pivot point of the five-way shaft, and measures the magnitude of the pulling force to know the pedaling pedal. Torque value, and the tension of the five-way shaft is measured by the principle of the spring crushing scale to measure the displacement of the five-way shaft, and then the torque sensing and the deformation calculation are used to achieve the purpose of the torque sensing. However, it is only applicable to the structural design of the five-way pipe and cannot be widely applied. Combining the above various conventional techniques, although it can be applied to a power-assisted electric bicycle, thereby sensing the torque state of the electric bicycle when rotating, the sensing device is disposed on the rotating mechanism (such as a five-way shaft), The sense signal output is a large M430429 problem. If the sense signal is transmitted by the wire, it may cause the wire to be broken due to the continuous rotation of the rotating device; if the rotary brush mechanism is used When the signal is transmitted, it is easy to install because the installation cost is high, and after a long period of electrical friction, it is easy to cause the electric structure to be deformed, so that there is a conductive contact failure, which causes the signal transmission. The interruption of the failure to start the motor occurs, resulting in inconvenience in use and great trouble. In view of the above-mentioned lack of various torsion sensing devices, the creator has actively worked hard to study, and finally experimented and implemented, and finally produced the results of the creation. [New Content] The purpose of this creation is to provide a torque sensing simplification, stability and strength, easy assembly, low cost and good sensing effect, mainly to convert the force applied to the crank into an angle. The amount of displacement, which in turn is converted into a torque sensing signal, allows the user to reach the county in the long distance or New Zealand road conditions to achieve maximum exercise break. The technical means for achieving this purpose include a shaft, a crank, a moving force transmitting member, a rotating member, a connecting seat, a moving member, a spiral torsion, a magnetic element, and a magnetic sensing element. The two ends of the torsion spring respectively position the connecting seat and the rotating member, and when a torque is generated between the crank and the power transmitting member to overcome the elastic force of the torsion, the connecting seat rotates from the first angle to the second angle with respect to the rotating member, and the moving member The guided structure is pushed obliquely by the guiding structure and is displaced from the first position to the second position along the + central axis. When the torsion does not overcome the elastic force of the torsion spring, the elastic force of the torsion spring causes the connecting seat to rotate to The first angle and the shifting scale are moved to the first position, and the force applied by the rider to the _ can be converted into the displacement amount first, and converted into the torque sense M430429 test signal as the basis for driving the motor. The second object of the present invention is to provide a torsion sensing device that does not require the use of a _-type brush mechanism to transmit sensing signals, thereby improving the quality of sensing and transmission of signals. The technical means for achieving this purpose include a shaft, a crank, a power transmission member, a rotating member, a connecting seat, a (four) member, a job force _, a magnetic component, and a magnetic sensing component. The two ends of the torsion spring respectively position the connecting seat and the rotating member, and when the crank generates a torsion force against the elastic force of the torsion spring, the connecting seat rotates from the first angle to the second angle with respect to the rotating member, and the moving member is The guided structure is obliquely pushed by the guiding structure and displaced from the first position to the second position along the central axis. When the torsion does not overcome the elastic force of the torsion spring, the return spring of the torsion spring causes the connecting seat to rotate to the first position. Angle and moving the moving member to the first position, wherein the magnetic sensing element is a Hall element, and the device is capable of sensing the magnetic state of the magnetic element at the position where the frame can sense the magnetic state of the magnetic element The force of the crank is first converted into an angular displacement, which is then converted into a torque sensing signal as the basis for driving the motor.

As the basis for driving the motor. 2· 2 The specific architecture is shown in FIG. 2 and FIG. 4 . In a specific embodiment, the guiding structure 21 and the guided structure 41 are divided into two parts, and are equally spaced. Rotating member 20 and moving member 40. Specifically, the guiding structure 21 shown in FIG. 2 and FIG. 4 is the guiding groove 21a', and the guiding structure 41 is the protruding column 41a, and the protruding column can be used to enclose the guiding groove 21a in the guiding groove 21a. The end is a closed end and the other end is an open end. The specific structure of the rotating member 2 includes a circular body 22 and a ring wall 23 surrounding the end edge of the body 22. The (f) end of the guiding groove 21a is located at one side of the ring wall 23, and the body 22 The center is provided with a round hole 220, and the ring wall 23 is provided with a plurality of guide grooves 21a. The connecting seat 30 includes a ring body 31 having a first ring wall 310 extending toward the edge of the round opening 22, and a recessed inner edge of the first ring wall 310. A circular groove 311 is formed at the top of the crank 12, and a shaft is provided through the inner edge of the circular groove 311. A through hole 312, the opposite side of the ring body 31 is provided with a second ring wall, and the moving member 40 has a circular hole 42 through which the second ring wall 313 extends. In addition, the moving member 4 is disposed with a plurality of guide posts 43 facing one surface of the connecting base 30. The connecting block 3 is provided with a plurality of guiding holes 32 for the displacement of the guiding post 43. When the second angle is rotated from the first angle to the second angle, the moving member 4 is axially displaceable relative to the connecting seat 3 . Referring to FIG. 5 and FIG. 6 , in order to limit the relative angular displacement angle of the rotating member 2〇 and the connecting seat 3〇, a positioning plate 7〇 is fixed to the connecting base 30, and the power transmission 9 M430429 is transmitted. The center of the 13 is provided with an i-shaped port (10), and the mouth of the port (10) is equidistantly arranged with a plurality of circular arc extensions _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The card edge 71 is located in the card slot 131. The width of the card slot (3) is greater than the width of the card edge 71. When the connector block 3 is rotated relative to the rotating member 2 from the first angle to the second angle The card edge 71 is moved from the end of the card slot 131 to the other end to form a carding state, and the difference between the first angle and the second angle is not more than 10 degrees. The positioning plate 7 is different from A baffle 80 is disposed on one of the connecting seats 3 〇. Not only that, the present embodiment is provided with a technical feature including a control unit, a motor, and a battery pack on the frame body 1 , because the control unit, the motor, and the battery pack are not part of the county. Mark the assignment. When the magnetic sensing component 61 senses the position of the side of the miscellaneous element, the control unit inspects the battery pack to supply power to the motor, so that the motor operates to drive at least one wheel of the frame body 1 . For the specific operation of the present creation, please refer to FIG. 1 and FIG. 4 to FIG. 6 , when the user rides the electric assist bicycle, only the pedal 15 is required to perform the reciprocating stepping force to input the power to the crank 12 due to the crank 12 . They are respectively connected to the two ends of the rotating shaft 11, so that the power can be received and rotated relative to the frame body 1, and the connecting seat 30 is fixed to the crank 12, so that the crank 12 can be synchronously rotated. When the user wants to accelerate or climb the hill, the user only needs to apply a large pedaling force to the pedal 15, since the two ends of the torsion spring 50 are respectively positioned between the connecting seat 3〇 and the rotating member 20, so the power The transmission member 13 (ie, the toothed disc) can be subjected to a large torque, M430429. In turn, a torque that causes a relative angular displacement between the coupling seat 30 and the rotating member 2〇, when the torsional force can overcome the elastic force of the torsion spring 50, The connecting seat 30 is rotatable from the first angle to the second angle with respect to the rotating member 2, and the guided structure 41 and the magnetic member 60 on the moving member 4 are tilted by the guiding structure 21 along the rotating shaft. The central axis direction is displaced from the first position to the second position. On the other hand, the magnetic sensing element 61 senses the magnetic field change of the magnetic element 60 (ie, is weakly converted) and converts the magnetic field change signal. For the corresponding electrical signal (ie, the sensing signal), and after the control unit converts the processing and solution #, a control signal is generated into the driving circuit, and then the driving circuit starts the motor to output the motor to assist the rotation of the bicycle wheel. move So you can not make enough physical effort of the user easier when riding over long distances or uphill section. Moreover, when the user rides on a generally flat road and there is no need for acceleration, the user only needs to apply a normal pedaling force to the crank 12 through the pedal 15, and the power transmission member 13 (ie, the toothed disc) can be subjected to a comparison. The small torque acts to drive a relatively small torque between the connecting seat and the rotating member 20. Since the torque cannot overcome the elastic force of the torsion spring 50, the return spring of the torsion spring 5 turns the connecting seat 30 to the original position. The first angle 'At this time, the moving member 40 and the magnetic member 60 are still in the first position. On the other hand, the magnetic sensing element 61 senses the weak magnetic field of the magnetic member 60 and converts the magnetic signal into a corresponding one. The electrical signal (that is, the sensing signal) is converted and processed by the control unit. Since the magnetic field strength represented by the sensing signal fails to exceed the preset value, the control unit does not start the motor operation, so the rider must Its own pedaling force allows the electric assisted bicycle to move forward. Therefore, with the above-mentioned structure setting, 'this creation does have the following characteristics: 11 M430429 1. This creation not only has the characteristics of obviousness, stability and strength, is easy to assemble, low in cost and good in feelings, etc. Converting the power of the sci-fi machine into an angular displacement, and then converting it into a torsion _ position, let the (four) people take a long ride or climb the road to 'free ride, to achieve the maximum sports break. 2. This creation does not require the setting of the rotary brush mechanism, so it can avoid the lack of signal products caused by the brush mechanism transmitting the sensing signal, thereby improving the sensing and transmission quality of the signal.
