Description

1269747 玫,发明说明: [Technical Field] The present invention overcomes the problem of controlling gear movement in a bicycle and has been developed and applied to competition (4) treadmills. In any case, the application of this possibility, in particular the application of the early use of the race, should not be construed as limiting the possible fields of the invention. [Prior Art] In the past few years, many developments have been made in the field of bicycles. Related features of the bicycle sensor, Shaw to obtain a lot of information about the use of the device, the action, its purpose can be intervened by the actuator, modified according to certain rules, and in a automatic manner and specific instructions issued by the user You have a role in the use/action characteristics of the device set by i. In particular, the present invention has been developed with particular reference to a servo system that positions the drive chain of the bicycle in a position equivalent to the front and rear derailleurs. In the drive gear set mounted on a more sophisticated bicycle, it is assumed that the crankshaft and the sprocket toothed by the transmission do not define the same teeth. Conversely, the teeth are arranged in groups in an orderly manner, and the teeth contained in each group have a sequence of differential geometries to promote the movement of the chain, as described above, in a relatively toothed shape, point or region, The movement of the chain is promoted. This point or area is simply referred to as "伲 " κ进部分".

If an instruction to move the chain position is issued without dropping A 乂 *, the correct positioning of the chain can be temporarily suspended, delayed and delayed. 3 1269747 It has become the most troublesome thing in a bicycle, where = is controlled by an automatic actuator, and the actuator is controlled by an electronic control system. This system is usually constructed as an improved interface for the combination of the bicycle and the bicycle itself (in accordance with the use of the _, ^ ^ 7 and fully automatic), so that the bicycle 'and more usually the bicycle, so that The performance of the user system can be optimized. For example, in addition to the non-opening/T stop when the command is actuated, a problem that occurs long is that the actuator is activated after the command stops π丨τ. Time (and thus energy), so the actuator itself is enthusiasm to determine if the action should proceed. During this period, the actuator absorbs energy (generally a battery) from the supply power supplied to the bicycle. This installation absorbs energy and is totally wasted without any useful results. SUMMARY OF THE INVENTION It is an object of the present invention to provide a solution that overcomes the above disadvantages. In accordance with the present invention, this object is achieved by a program having the specific features described in the scope of the following claims. The invention also relates to corresponding systems, as well as elements that can be used in the above systems and, or in the above described procedures. Basically, the solution of the present invention is to use a thought that leads to the usability of the control system available on the bicycle, especially on the racing bicycle, "the purpose of obtaining information can be used to optimize the energy supply and avoid the use of the system. The waste of energy, which proves to prevent the bicycle from being cumbersome and/or too heavy, so that the battery must be in the preferred embodiment, the hair can be broken into a crankshaft type converter with a bicycle, which can be used for testing - The movement of the transmission components of the bicycle - driven by the crankshaft axis (or "phase"); and the pedal rhythm. This message can be at least partially conditional from the source of the power supply, such as the movement of the foot actuator. This is especially applied in the introduction section on the movement at the most favorable moment. "The promotion department in this respect must mention the movement of the piece, only the component itself is moved to cause energy waste and mechanical components. However, a direction that simply and simply moves in the opposite direction to the desired direction is in the opposite direction. Therefore, the solution of the present invention generally moves and the direction is the same in the desired direction, and is known in one direction. In the angular position (according to the application of heavy load. The scheme includes using the converter, it "" alignment. This is preferably a potential calculation, such as: (can be a chain or belt); the corresponding tooth angle of the gear The position 'used in the action of the bicycle component is the sum of the energy extracted by the battery on the treadmill itself' or the operation of the rear derailleur as the 'when the chain is corresponding to the copy.' It is generated appropriately for the movement of the element of motion; otherwise, there is a risk of undesired stress. The signal is not enough, if the chain is moving (ie Along with the pedals, the pedals will again produce undesired results. Including, according to the chain itself, it is confirmed (that is, whether the gear involved in the movement of the gear before the bicycle is along with the pedal is equivalent to The operation of gear shifting is performed corresponding to the chain position in the position of one of the 1269747 parts of the above-mentioned promotion unit. [Embodiment] In the drawings, the symbol 1 is a bicycle as a whole, such as a bicycle for racing. The structural and structural features are considered to be identical and therefore need not be described in detail herein. In this regard, it is known to those skilled in the art that the possibilities of using the inventive arrangements are not limited to the illustrated pedaling model. In the presently preferred embodiment of the invention, a sensor 2 is used in a position corresponding to the crankshaft axis C1. In embodiments in which the invention is considered to be less used, a second sense can be used. The detector 3 (which can be used together with the sensor 2 or replaces the sensor 2) is mounted at a position corresponding to the chain tensioner. In the first and second figures, the sensors 2 and 3 coexist, only for Make this article too The system additionally includes two actuators 4 and 5, each designed to control the front and rear derailleur of the bicycle. Sensors 2 and/or 3, and actuators 4 and/or 5, individually connected The line (not visible in the figure 'but in the conventional form) is connected to the program unit 6 which is preferably at least partially located near the handle of the bicycle. In terms of procedures and systems, the invention relates to a form which is in accordance with the bicycle transmission ratio. In another aspect, the invention relates to a preferred solution for obtaining sensors 2 and 3. 6 1269747 In any case, at least in terms of procedures and systems, the inventive solution and sensor 2 The specific features of 3 are independent of the specific features of the actuators 4 and 5. Moving to the detailed configuration of the reference sensor 2 (Fig. 3), it can be noted that it basically comprises a stator element 10 which contains a A small disc made of a resistive material is placed at a position fixed to the skeleton of the bicycle 1. In particular, the stator element 10 has a central opening 12 which allows the crankpin 1 of the crankshaft axis C1 of the bicycle to pass. Mounted on the stator element 10 are concentric circular channels each on the outer and inner strips 14 and 16, both of which are electrically conductive, and at least one of which (e.g., strip 1 4 in the legend) is Made of a resistor material. The ends of the strips 14 are terminated by two end pins 1 40 and 14 1 , respectively, which are connected to: - a power supply source V (which can be used in a power supply battery mounted on a bicycle in a conventional manner) One), and a ground terminal G. The connection of the pin 1 40 to the power supply source V is preferably the power outlet switch 150, the function of which will be described in more detail below. The inner strip 16 should here be only one strap, made of a metallic material, which is connected to another pin 1 42, and then connected to the program unit 6. At the same time, another pin 1 43 is connected to the program unit 6, and is then connected to a mat 1 8 made of electrically conductive material. The mat is placed between the strips 24 and 16 corresponding to the end of the strip 1 4 itself. One of the values in the point. The combination of the above elements basically forms a resistive voltage divider, in which the voltage level can be detected on the pin 1 42 once the value of the supply voltage V applied to the pin 144 is set in 7 1269747, basically The position of the upper view brush 20 depends on the angular position and thus on the angular position of the crank pin H1. When the brush 20 slides over both of the strips 14 and 16 , it will be in the strip 14 (here formed as a split ring, the ends of which are connected to pins 140 and 141 which are close to each other but not connected to each other) ) Establish an electrical connection with pin ι6 (here assumed to have a continuous circular unfolding 'and made of electrically conductive material).

Each time the crank pin H1 of the bottom bracket rotates one turn, the pad U and the pin 143 connected thereto are short-circuited to, for example, the pin 141 and/or the connected strip 14, thereby forcing the pin 143 to become a ground voltage. The output signal of the sensor 2 is basically a mineral toothed letterhead, which is located in a corner room of the sputum pin Η1, 饮0 0 Λ month position which is equivalent to the brush 2 〇 in the channel corresponding to the pin ΐ 4 At the end of position 14, the maximum value is reached, and at crankshaft d, the system 20 is confined to the opposite end of the passage 14, i.e., at the point corresponding to (6) 141, the minimum (final, zero) is reached.

The above-mentioned ore-like signal has a sharply rising peak or an obliquely downward acute angle. Under the same mounting position of the sensor 2, the crankshaft axis is clearly transmitted all the way, and thus depends on the direction of rotation of the chain κ. In any case, the appropriate setting of the limit setting (directly performed on the analog signal on pin 142, or by the analogy of the transmission/acquisition phase-to-digital conversion) The connected gear (in this embodiment two: "ground identification, ~ moving" 'is in the opposite position located in a promotion: 疋 self-axis axis, that is, in the tooth section: Position: At the beginning, it can promote the transmission of the 3-8 to the zipper to identify the movement of the inner conductor strip 14 by the conductive 1269747 chain K. In addition, the appropriate operation of the above limit setting is again observed. When the output signal of the sensor 2 is proved to change with time, the corresponding gear and the chain K are moving. Finally, the detection of the slope (angle factor) of the front and/or the back end is made, so that the single button K itself The direction of movement (forward or backward). The combination of the above elements can be made into a mechanical mechanical component similar to a conventional rotary potentiometer, with a housing that can be inserted into the housing or, in any case, inserted into a protective structure; So-called "planting "Middle", even in a harsh environment, when it is mounted at the position equivalent to the crankshaft axis of the bicycle, on the other hand, it is known to those skilled in the art that many variations can be made in this embodiment (the preferred embodiment). For example, the roles of strips 1 4 and 16 are reversed (ie, the strips 16 are made of a resistive material); the corners of the brush 20 and at least two of the strips 14 and 16 are opposite, ie, The brush 20 is mounted in a static position and the strip rotates with the crankpin H1 of the crankshaft axis; or the mat 18 is clamped at a position corresponding to the pin 140; A, the brush 2 passes mat! 8 is no longer forced to ground t, -θ ^, 夂 ground voltage, but battery voltage V. Further variations of the embodiment are also known to those skilled in the art, in which a 4 4 β σ potentiometer type sensor can be used, which can be used.

142, in the icon meeting #,1, ^士^J 例 例)) supply a first signal, ^ 匕 匕 'unit 6 shows that the cell 6 in its discussion can be confirmed, the basic components to a t Medium (for example, correct operation. When made in the current f material, the two of the dynamic phases are ^1 4 end parts into the pin 143 to understand the range red out point (in the excellent 1269747 to confirm the crankshaft axis of the crankpin Η 1 At the current angular position, a reference signal can be generated to indicate that the crank pin 1 passes the predetermined angular position, and a signal can confirm the movement and movement direction of the chain 。. However, the sensor 3 is made to be loaded. In a position equivalent to a chain tensioner, the tensioner is usually mounted at a position corresponding to the rear end of the bicycle chain. The chain tensioner in question usually consists of a pair of oscillating arms or half cages 22, half cage 22 Each of the upper ends 24 is designed to be connected together to two points which correspond to cage bends or pivots 26 which allow the half cage 22 to be mounted on the bicycle 1 frame and which can be carried around the cabinet axis 26 extending in the horizontal direction. Oscillation. The top pulley or roller 25, typically having a hyperbolic lens profile, is mounted between the upper ends to 'rotate it about its own axis Χ 25. The arms are half-cage 2 2 and then each bottom end 28 is designed The cabinet shafts 3 are connected together, and a bottom pulley or spoke wheel 32 (generally having a hyperbolic lens shape) is mounted thereon and rotated about its own axis X 3 2. The bicycle chain K is installed. Formed at the top and bottom rollers 2 5 and 32, thus forming a generally S-shaped path. The resilience movement of the vibrating arm 22 about the axis X26 causes the corresponding movement of the bottom pulley or roller 32, The latter allows the chain κ to be in tension, thereby absorbing and compensating for changes in the path of movement of the chain K, which are produced by the chain itself engaging at different positions of the sprocket corresponding to the bicycle drive train. 10 1269747 In any case, the set of parts as described above and the corresponding operating rules; equivalent to the conventional solutions, and therefore need not be described in detail here, but also because they are not related to the application and understanding of the present invention. The configuration of the present invention causes at least one of the rollers 25, 32 (in the illustrated embodiment, the roller 3 2) to function as a rotor portion of the sensor, the stator portion of which is generally indicated at 34, and is mounted on the oscillating arm Or one of the half cages 22. The magnetic material element 36 (such as plastic ferrite) is applied at the point of the roller 3 2 (which may be formed integrally in the manufacturing process, such as common mode formation), as shown in the figure As shown therein, it has a C-shape that is generally coincident with a predetermined angle, such as an angular extension of 180. The stator portion 34 of the sensor preferably includes a two-end device or pick-up member 35, such as a Hall effect. The sensors, or reed switches, are mounted on the corresponding oscillating arms or half cages 22 at an angular position of 90° to each other with the axis of rotation X32 of the roller 32 interlaced. Figure 5 shows that in one of its two parts groups, one above the other, as indicated by a) and b), the possible sequence of rotation of the element 36 as the roller 32 makes one revolution is in accordance with the roller 3 2 in question. (See in Figure 5) Whether it is moving in the clockwise direction (Fig. 5a) or counterclockwise (Fig. 5b). Referring to the moving direction of the chain K engaged with the roller 3 2, the above two directions of rotation can be broken to correspond to the forward movement and the backward movement of the chain K itself. Recall that in this context, the term "forward" means that the direction of movement of the chain corresponds to the direction of movement of the bicycle when the crankshaft axis of the bicycle is driven along the direction in which the bicycle itself is propelled. 11 1269747 Similarly, the two parts a) and b) of Fig. 6 represent two time-history diagrams of the actions corresponding to the output signals of the two-terminal device or the L-receiving device 35, the two signals being 3 5 2 λ S ± _ ' indicates that it can be regarded as the second signal as the chain κ moves to just after (signal 352, 352 of Figure 6a) and backward (signal 352, 352 of Figure 6b). The above signal is substantially a logic signal (ie, the signal appears as a high logic level or a low logic level, according to the front end of each of the two ends of the device or the pickup member 3 5 through the magnetic material, or a distance from it And set). The logical combination of signals 352 and 352 produced by the two ends of the device or pickup 35 provides an excellent indication of whether the movement of the roller 32 (and thus the chain κ) is produced in one direction or the other. All of these occur in accordance with conventional rules (for example, from the technique of the so-called r optical encoder), and need not be described again here. The sensor 2 can also be applied to the sensor 3 as before. Those skilled in the art will be able to define functionally the same as those just described, in light of the foregoing teachings. In particular, the above sensing effect can be performed by using the roller 2 5 instead of the roller 3 2, or using a different sensor or pickup member than the foregoing, or again, using two sensors, one of which is connected Go to one roller and the other to another. However, the 'must indicate' is mainly from a technical point of view (connected to the roller 3 2 of the magnetic material element 36), and the scheme just described proves to be particularly excellent, in which it can obtain a simple and reliable sensing. The combination of the devices, in addition to providing low power consumption, and proper operation even under harsh environments, 12 1269747 is used, for example, on bicycle transmissions. ~ Again on the power consumption, it has been mentioned that a component 5 g is connected to the sense of 2, 70 pieces of 150 power switch function, when the corresponding sensing function does not need to be 'can cut off The connection of sensor 2 to voltage source v. In particular, although the switch 150 is in the open position, the resistive element of the strip 14 is not connected to the voltage source v and thus does not absorb electrical energy. Switch 1 50 is preferably connected to unit 6 by individual wires i 5 such that sensor 2 itself is actually activated only when signal 6 is deemed to be available. This typically occurs when unit 6 is available (because it can receive a forward command from the outside bicycle user, or because of the special conditions of unit 6 itself operating in accordance with the bicycle) to obtain a change in the bicycle transmission ratio. In the sensor 3, a similar configuration is also provided, that is, the switch 152, which only activates the two-terminal device or the pickup member 35 when the corresponding actuation signal is received from the unit 6. The form of the action of the front derailleur will be described with reference to the presently preferred embodiment of the present invention, i.e., assuming that only the sensor 2 is present, it can supply the signal processed by the unit 6 to confirm the crankshaft of the bicycle. The angular position of the heart, thus the angular position of the gear driven by the latter, and the direction of movement and movement of the chain K. When the need to change the ratio of the front transmission gear ratio occurs, the unit 6 acts as a dynamic actuator 2 (e.g., by a switch 150, typically an electronic switch, such as a transistor) to a closed position to actuate the sensor 2 itself. The 13 1269747, which is picked up on the pin 142, corresponds to the output signal, so that the unit 6 can confirm the angular position reached by the crankshaft pin 1 of the crankshaft axis in an excellent manner, and the corresponding gear, and thus the movement and movement direction of the chain K. The above purpose is to enable the unit 6 to make the corresponding actuator (in the illustrated embodiment, the actuator 4 is connected to the front derailleur) to be properly advanced to properly move the chain as required, while It has also been detected that the chain Κ moves forward, thus preventing any attempted gear movement when the chain is stationary or when the chain is moved backwards.

This mode of operation is shown schematically in the flow chart of Figure 7. Here, starting from the initial step 100, step 101 confirms that the unit 6 receives (or, in any case, processes) a chain positioning command, i.e., a request for gear movement. The next step 102 is where unit 6 actuates sensor 2 to have a corresponding signal available.

At selection step 103 (its function will be shown below, and it is assumed here to have an output NO), the signal from sensor 2 is verified in step 104 if the chain is actually moving. The output NO of step 1 04 indicates that the chain K is not moving. In these cases, unit 6 returns to step 103. However, the output YES of step 104 indicates that the chain K is moving, and then in the next step 105, unit 6 verifies whether the signal from the sensor 2 indicates that the chain chain is moving forward. The output NO from step 105 is caused to return to step 103. If YES is output from step 106, unit 6 verifies in the next step 106 whether the sensed signal value of 14 1269747 2 indicates that the chain is in one of the positions corresponding to the movement facilitating portion. Also in this case, if NO is output, unit 6 returns to step 103. On the other hand, if YES is output, unit 6 sends a command to move the gear (step 107) to actuator 4, which also stops the sensor. Then move to a catch step 1 0 8.

If, based on a number of the aforementioned specific reasons (the chain is stationary or moving backwards, at a position that does not correspond to the facilitating portion), unit 6 returns to step 103 where unit 6 verifies whether or not processing gear movement is received from unit 6 itself. The elapsed time of the instruction is longer than the predetermined limit value of T. If the time period is shorter than the threshold value (from the output NO of step 103), the unit 6 repeats the sequence of the foregoing steps to simultaneously verify whether the user has activated the foot pedal again, thereby causing the chain K to move forward, especially The chain is brought into a position equivalent to one of the facilitating portions to establish an indication that the gear movement is advantageous.

However, if the condition is not conducive to the movement of the chain for a certain period of time (YES from step 103), unit 6 moves to step 109, thereby interpreting the received or processed gear movement command as an unexecutable command, possibly because it has been mistaken. The mode is issued and thus a reset is performed to clear the gear movement command; then it moves to a final step 110. Under these conditions, for example, unit 6 can send a signal to the user (e.g., an audible and/or optical signal) for the purpose of indicating that even if the user has issued a gear movement command, his action cannot be synchronized with the command issued. Anastomosis (for example, because he does not step on the pedal, or he steps back). 15 1269747 It should be understood that the above-described operational rules can be performed in a sub-optimal manner, operating only in accordance with the signal of the movement and movement direction of the chain K, which is performed under the condition that the gear movement is excellent in the forward movement of the chain K. In this case, the message of the gear angle positioning is clearly marked and the positioning information of the chain κ to the movement promoting portion is not obtained. It is a matter of course that the details of the construction and the embodiments may be varied widely and varied from those shown and described herein without departing from the scope of the invention. This applies in particular to the application of the aforementioned operational rules to the gears of the crankshaft axis (and thus to the corresponding transmission) and to the rear gearbox only. In principle, the position of the chain κ can also be sensed, in particular by a salt detector such as the sensor 3 connected to the chain tensioner, and sensing the position of the #-toothed shape moved by the crankshaft axis Furthermore, another variant embodiment also uses the sensor 2 to generate the angular position signal of the tooth dry and the signal used by the sensor 3 to generate the direction of movement and movement of the chain κ. This solution is based on the use of the sensor 2 alone, which is particularly excellent in terms of system accuracy and operational reliability.
