Description

[0001] This application claims priority to U.S. Provisional Patent Application 63 / 703,562, filed October 4, 2024, the entirety of which is hereby incorporated by reference herein. TECHNICAL FIELD

[0002] The present disclosure relates to bicycle components, and more particularly to position detection devices for bicycles. BACKGROUND

[0003] Bicycles are known to have movable components. Movable components include brakes, suspensions, height adjustable seat posts, and the like. Measurements of these components can provide useful feedback about how the components are working. Brake components can move between various positions corresponding to lever travel, brake pad position, brake force, and the like. Suspension components can move between various positions corresponding to axle position, wheel travel, and the like. To provide feedback for adjustment and control, accurate position detection of bicycle components is desirable.

[0004] Accordingly, there is a need for bicycle components that facilitate position detection in various modes of operation. SUMMARY

[0005] It is an object of the present disclosure to describe various position detection devices for bicycles. Position detection devices can be used to provide data to riders and adjusters. For example, a position detection device can be provided to determine the position of a brake component during operation, generating position information related to brake operation. Such brake position information can be used for brake adjustment purposes, control of other components such as suspensions, and / or control of drive motors as in electrically assisted bicycles or e-bikes. Position data can be generated at time intervals close enough to determine useful speed data of position changes. For example, a height adjustable seat post can be measured to determine if an extension speed indicates a need for maintenance. Detailed position data can be used to map positions, speeds, accelerations, or more parameters of various components, and the like. For example, a suspension component can be mapped relative to average position, minimum position, maximum position, minimum speed, maximum speed, minimum acceleration, maximum acceleration, and various other aspects. Accurate and rapid position detection of bicycle components described herein serve as a basis for bicycle setup guidance and confirmation, and can also be used to provide useful ride data to a rider or even a wider group of riders selected by the rider.

[0006] One aspect provides a position detection apparatus for a bicycle, the position detection apparatus comprising: a bicycle component defining an interior and an exterior; a detectable element disposed in the interior of the bicycle component, the detectable element movable relative to the bicycle component; at least one detection element disposed in the exterior of the bicycle component, the at least one detection element operable to detect: a first position of the detectable element relative to the bicycle component, and a second position of the detectable element relative to the bicycle component, wherein the second position is different than the first position.

[0007] Another aspect provides a position detection apparatus for a bicycle, the position detection apparatus comprising: a bicycle component defining an interior and an exterior; a field generating element disposed on the interior of the bicycle component and generating a field detectable in the exterior of the bicycle component; and at least one detection element disposed in the exterior of the bicycle component, the at least one detection element operable to detect the field generated by the field generating element.

[0008] Yet another aspect provides a position detection apparatus for a bicycle, the position detection apparatus comprising: a first component; a detectable element disposed on the first component; a second component movable relative to the first component along an axis through a range of travel; a first detection element disposed on the second component, the first detection element operable to detect the detectable element during a first portion of the range of travel; and a second detection element disposed on the second component, the second detection element operable to detect the detectable element during a second portion of the range of travel, the second portion of the range of travel distinct from the first portion of the range of travel.

[0009] Yet another aspect provides a suspension component for a bicycle, the suspension component comprising: a first tube defining a first tube volume; a second tube at least partially disposed within the first tube volume, the second tube defining a second tube volume; a detectable element fixed relative to the second tube and at least partially disposed within the first tube volume; and at least one detection element disposed outside of the first tube volume and the second tube volume.

[0010] Yet another aspect provides a method for detecting a position of a bicycle component, the method comprising: moving a detectable element along a travel path between a first position and a second position; generating, with a first detection element, a first output based on movement of the detectable element from the first position to the second position; generating, with a second detection element, a second output different than the first output based on movement of the detectable element from the first position to the second position; and determining, with a processor, position data based on the first output and the second output.

[0042] The drawings can not be to scale. Instead, the dimensions of the various layers or regions can be exaggerated in the drawings for clarity. Generally, the same reference numbers can be used to refer to like or similar components throughout the drawings and the following written description.

[0043] Other aspects and advantages of the embodiments disclosed herein will become apparent from consideration of the following detailed description, taken in conjunction with the accompanying drawings, where like reference numerals designate like elements in the figures. DETAILED DESCRIPTION

[0044] Reference will now be made in detail to implementations of the present application, one or more examples of which are illustrated in the drawings. The detailed description uses numerical and letter designations to refer to features in the drawings. Like or similar designations in the drawings and description have been used to refer to like or similar parts of the application.

[0045] As used herein, the word "exemplary" is used to mean "serving as an example, instance, or illustration." Any implementation described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other implementations.

[0046] ​​​Descriptors used herein, including the terms“first,”“second,”“third,” and the like, can be used interchangeably to distinguish one component from another and are not intended to signify location or importance of the individual components. Unless based on context or understanding of the usage of such descriptors, such descriptors are not intended to imply any priority or chronological order of one component over another, but are used as labels for ease of discernment of the individual elements or components so as to facilitate the understanding of the disclosed examples. In some examples, the descriptor“first” can be used in the detailed description to refer to a certain element, while in the claims, the same element can be referred to using a different descriptor (such as“second” or“third”). In such instances, it should be understood that such descriptors are used merely for ease of reference to the multiple elements or components.

[0047] The terms“coupled,”“fixed,”“attached to,” and the like, mean either a direct coupling, fixation, or attachment or an indirect coupling, fixation or attachment via one or more intermediary components or features, unless specifically stated to the contrary.

[0048] The singular forms“a,”“an,” and“the” include plural referents unless the context clearly dictates otherwise.

[0049] Approximating language as used herein with respect to a quantitative representation of a value is applied to modify a quantitative representation which can vary without resulting in a change in the basic function to which it is related. Accordingly, a value modified by a term or terms, such as“about,”“approximately,” and“substantially,” are not limited to the precise value specified. In at least some instances, the approximating language can correspond to the precision of an instrument for measuring the value or the precision of the methods or machines for constructing or manufacturing the components and / or systems. For example, the approximating language can refer to being within 1%, 2%, 4%, 10%, 15%, or 20% of the specified value.

[0050] As used herein, and throughout the specification, range limitations can be combined and interchanged, such ranges being identified and include all the sub-ranges contained therein unless context or language indicates otherwise. For example, all ranges disclosed herein are inclusive of the endpoints and operate as "open-ended" ranges in conjunction with the "approximate" language as used herein.

[0051] Various suspension components can be provided with reference to the following disclosure. For example, front suspension forks, rear suspension shock absorbers, seat posts, and various other suspension components are contemplated in connection with the following features. Continuing with the example of the front suspension of a bicycle, a front fork generally includes a crown, an upright tube extending upwardly from the crown, and two fork legs extending downwardly from the crown. Each fork leg has an upper tube connected to the crown and a lower tube to be connected to a front wheel. The upper and lower tubes are arranged in telescoping relation. In some cases, a shock absorber is provided in one of the fork legs, and a spring (e.g., air spring, coil spring) is provided in the other fork leg. When a rider traverses a bump or obstacle, the spring can compress or collapse the front fork, thereby reducing the impact and vibration transmitted to the rider, and then return the front fork to an extended state after the compression force is removed. In air springs, there can be danger if the pressure contained within the suspension component is suddenly released.

[0052] Suspension components on bicycles can employ position detection devices. The position detection devices described herein can operate to measure the travel position of various suspension components. Such travel measurements can be performed once (e.g., for assistance in pre-ride setup), periodically (e.g., for confirmation of measurements throughout a ride), or continuously (e.g., for tracking and reporting travel derivatives such as suspension velocity and acceleration). It is desirable to implement position detection without interfering with suspension operation. For example, it can be advantageous to provide position detection devices to detect the position of a suspension component wirelessly.

[0053] Example suspension components with position detection devices are disclosed herein. In various examples, the position detection devices described herein can operate to measure the travel of a suspension component. The position detection devices can be implemented wirelessly, for example, to communicate across one or more elements of the suspension component. Generally, the position detection devices can detect, store, and transmit suspension position data as described herein.

[0054] Referring now to the drawings, Figure 1 One example of a human-powered vehicle is illustrated, on which the example front fork disclosed herein can be implemented. In this example, the vehicle is a type of bicycle 100, such as a mountain bike. In the illustrated example, the bicycle 100 includes a frame 102 and a front wheel 104 and a rear wheel 106 rotatably coupled to the frame 102. In the illustrated example, the front wheel 104 is coupled to a front end of the frame 102 via a front fork 108. The forward / front riding direction or orientation of the bicycle 100 is indicated by the direction of arrow A in Figure 1 In the illustrated example, the front fork 108 includes a crown 110, an upright tube 112 extending upwardly from the crown 110, and two fork legs 114 extending downwardly from the crown 110. Each fork leg 114 has an upper tube 116 connected to the crown 110 and a lower tube 118 to be connected to the front wheel 104. The upper and lower tubes 116, 118 are arranged in telescoping relation. In the illustrated example, a shock absorber 120 is provided in one of the fork legs 114, and a spring 122 (e.g., air spring, coil spring) is provided in the other fork leg 114. When a rider traverses a bump or obstacle, the spring 122 can compress or collapse the front fork 108, thereby reducing the impact and vibration transmitted to the rider, and then return the front fork 108 to an extended state after the compression force is removed. In air springs, there can be danger if the pressure contained within the suspension component is suddenly released.

[0055] In Figure 1In the illustrated example, the bicycle 100 includes a seat 110 coupled to the frame 102 (e.g., near the rear end of the frame 102 relative to the forward direction A) via a seat post 112. The bicycle 100 also includes handlebars 114 coupled to the front fork 108 (e.g., near the front end of the frame 102 relative to the forward direction A) for steering the bicycle 100. The bicycle 100 is shown on a riding surface 116. The riding surface 116 can be any riding surface, such as the ground (e.g., dirt road, sidewalk, street, etc.), a man-made structure above the ground (e.g., a wooden ramp), and / or any other surface.

[0056] In the illustrated example, the bicycle 100 has a drivetrain 118 that includes a crank assembly 120. The crank assembly 120 is operably coupled to a sprocket assembly 124 mounted on a hub 126 of the rear wheel 106 via a chain 122. The crank assembly 120 includes at least one (typically two) crank arm 128 and a pedal 130, as well as at least one front sprocket (or cassette) 132. A rear derailleur 134, such as a derailleur, is provided at the rear wheel 106 to move the chain 122 between different sprockets of the sprocket assembly 124. Additionally or alternatively, the bicycle 100 can include a front derailleur (not shown) to move the chain 122 between different gears of the cassette 132.

[0057] The example bicycle 100 includes a suspension system having one or more suspension components. The front fork 108 is or is integrated with a shock absorber that includes a spring and a damper, which are disclosed in greater detail herein. In addition, in the illustrated example, the bicycle 100 includes a rear suspension component 136 that is a shock absorber, referred to herein as a rear shock 136. The rear shock 136 is coupled between two portions of the frame 102 (including a rear triangle, also referred to herein as an arm 138) that is coupled to the rear wheel 106. The front fork 108 and the rear shock 136 absorb impacts and vibrations when the bicycle 100 is ridden (e.g., when ridden over rough terrain). In other implementations, the front fork 108 and / or the rear shock 136 can be integrated into the bicycle 100 in other configurations or arrangements.

[0058] Still referring to Figure 1The illustrated bicycle 100 can implement at least one position detection device. In the illustrated embodiment, a front position detection device 140 and a rear position detection device 142 are implemented. The front position detection device 140 is mounted to be connected to the front fork 108. At least a portion of the front position detection device 140 can be integrated with the front fork 108. For example, the front position detection device 140 may include an internal portion (not shown) disposed inside the front fork 108. The front position detection device 140 may further include an external portion (not shown) disposed outside the front fork 108. The front position detection device 140 may have one or more elements disposed on or integrated with the front fork 108 in a front position detection housing (not shown). As described in more detail below, the front position detection device 140 can be operated to detect the position of the front fork 108.

[0059] Figure 1 The rear position detection device 142 shown is mounted to connect with the rear suspension component 136. Although Figure 1 The rear position detection device 142 is configured to directly measure the position of the rear suspension component 136, but it should also be understood that the rear position detection device 142 can be implemented to detect the position of another component (e.g., rocker arm 138). The rear position detection device 142 may have one or more elements integrated with the rear suspension component 136. For example, the rear position detection device 142 may include an internal portion (not shown) disposed within the rear suspension component 136. The rear position detection device 142 may further include an external portion (not shown) disposed on or integrated with the rear suspension component 136. For example, the rear position detection device 142 may have one or more elements disposed in a rear position detection housing (not shown) disposed on or integrated with the rear suspension component 136.

[0060] As described above, the front position detection device 140 and / or the rear position detection device 142 can operate to detect the position of the corresponding suspension components. The front position detection device 140 and the rear position detection device 142 can detect, store, and transmit data indicating the position of the corresponding suspension components. Position detection can be performed during the suspension setup phase before riding or during riding. The position information generated using the front position detection device 140 and / or the rear position detection device 142 can be reported to provide information related to suspension travel, sinking, bottoming out, or more. For example, the collected position data can be used to generate average, median, or weighted average suspension positions over a sampling period (which can be a portion or the entire ride).

[0061] Position data collected with the front position detection device 140 and / or the rear position detection device 142 can be used for various downstream purposes related to suspension performance. For example, position data can be used to indicate maintenance recommendations based on total suspension travel distance or number of cycles. Riding and / or rider characterization can be further provided based on collected position data. For example, widely varying position data can indicate a rough or aggressive ride, while tightly constrained position data can indicate a smooth or easy ride.

[0062] Position data can be compared between multiple position detection devices. For example, data from the front position detection device 140 can be compared to data from the rear position detection device 142 to provide position balance data. Such position balance data can be used to indicate suspension balance, for example, relative to an average or recommended suspension balance. Suspension balance data can be used to provide rider characterization, for example, showing a more aggressive rider style where the range of travel detected by the front position detection device 140 is wider compared to the narrower range of travel detected by the rear position detection device 142.

[0063] Position data can be reported in real-time to one or more other components on the bicycle and / or to another device, such as a mobile device. Position data can be analyzed in real-time and / or reported in a post-ride report. Real-time data can be used in operations such as adjustment operations of the suspension or other components. For example, position data can be analyzed, which in turn can result in adjustments to suspension damping control, spring control, gear control, adjustable seat post control, or various other adjustable characteristics of the bicycle components. Post-ride reported position data can be used to track performance across multiple rides and / or to characterize ride data. For example, position data can be used in conjunction with GPS data and known locations such as trails to provide information about those trails. In various embodiments, position data matching a given trail can be used to characterize the trail in terms of roughness or difficulty and to suggest similar trails that the rider can enjoy or wish to avoid. It will be appreciated that a rider's position data can be compiled to provide a database of the rider's own suspension performance, or such data can be aggregated with other riders' position data to compare suspension performance and / or to generate average data indicative of a trail that can then be reported to other riders to aid in route planning.

[0064] Further processing of the position data collected by the front position detection device 140 and / or the rear position detection device 142 can generate further rider characteristic descriptions. For example, the rider can be provided with an objective post-ride "score" to indicate various riding characteristics, such as total air time, maximum compression, average ride height, number of compressions above a certain position threshold, etc. The post-ride "score" can be used to indicate an overall level of riding technicality and provide a benchmark for the rider, as well as to engage in social competition on various online platforms if the rider chooses.

[0065] Although Figure 1 A suspension arrangement is depicted, but in other implementations, in addition to or as an alternative to the front fork 108 and the rear shock 136, the suspension system can employ only one suspension component (e.g., only the front fork 108) or more than two suspension components (e.g., an additional suspension component on the seat post 112). Generally, the suspension components herein can include a first suspension element and a second suspension element that is movable relative to the first suspension element. A pressure chamber or other spring is provided to bias the first suspension element and the second suspension element, e.g., along a suspension axis. One of the first suspension element or the second suspension element is connected or connectable to a non-suspended portion of the bicycle 100 (i.e., a portion that is not suspended), while the other is connected or connectable to a suspended portion of the bicycle 100 (i.e., a portion that is supported by the suspension).

[0066] While Figure 1 The example bicycle 100 depicted in FIG. 1 is a mountain bike, but the example front fork (and / or lower housing or housing) disclosed herein can be implemented on other types of bicycles. For example, the disclosed front fork can be used on road bikes, as well as bicycles having mechanical (e.g., cable, hydraulic, pneumatic, etc.) and non-mechanical (e.g., wired, wireless) drive systems. The disclosed front fork can also be implemented on other types of two-, three-, and four-wheeled human-powered vehicles. Further, the example front fork can be used on other types of vehicles, such as motorized vehicles (e.g., motorcycles, automobiles, trucks, etc.).

[0067] Turning now Figure 2 A schematic view of the position detection device 200 is provided. Figure 2 The position detection device 200 of FIG. 2 can generally be implemented as Figure 1front position detection device 140 and / or rear position detection device 142, or as any other position detection device described elsewhere herein. Generally, the position detection device 200 includes at least one of the detectable elements 216 that can be detected by the first detection element 220 and the second detection element 222. The first detection element 220 and the second detection element 222 can be used to determine position data with the detectable elements 216. For example, the first detection element 220 and the second detection element 222 can be used to determine a position (e.g., an extension position) of a bicycle component by detecting the detectable elements 216.

[0068] As shown in Figure 2 , a first extension component 202 is provided. A second extension component 204 is also provided that is movable along an axis T. In various embodiments, the first extension component 202 and the second extension component can be referred to as extension suspension components, extension brake components, or with other suitable modifiers. The second extension component 204 is movable relative to the first extension component 202 along the axis T. The first extension component 202 and the second extension component 204 can each be configured as various components, including brake components or suspension components. As described herein, reference will be made to suspension components, but it will be understood that similar features and arrangements can be employed with reference to brake components, for example as described below with reference to Figure 14 .

[0069] Still referring to Figure 2 , an internal volume 206 can be defined between the first extension component 202 and the second extension component 204. The internal volume 206 shown is sealed from the external environment 208 by a sealing element 210. The sealing element 210 is shown schematically in Figure 2 , but can be provided as any dynamic sealing arrangement that allows for relative motion between the first extension component 202 and the second extension component 204 while maintaining a seal. For example, the sealing element 210 can include one or more of an O-ring, a quad lip seal, a labyrinth seal, or a lip seal. The sealing element 210 can also include or cooperate with lubrication features (not shown), such as a foam element that retains lubricant.

[0070] Figure 2Embodiments also illustrate various alignment features. A first alignment feature 212 is disposed proximate to the seal element 210. A second alignment feature 214 is disposed spaced apart from the first alignment feature. The first and second alignment features 212, 214 can be spaced apart along the axis T as needed for alignment, for example to resist relative motion between the first and second telescoping members 202, 204 caused by a force component perpendicular to the axis T. The first and second alignment features 212, 214 can be configured with bearing surfaces to facilitate telescoping motion between the first and second telescoping members 202, 204. In embodiments, the first and second alignment features 212, 214 are configured as bushings fixed to the first telescoping member 202 and slidable relative to the second telescoping member 204. One or more lubrication retention features (not shown) can be provided in the first and / or second alignment features 212, 214.

[0071] Still referring to Figure 2 A detectable element 216 is disposed in the interior volume 206. As shown, the detectable element 216 is fixed relative to the second telescoping member 204 in a detectable element housing 218. The detectable element housing 218 can be formed as a recess in the second telescoping member 204, or can be a separate element that holds the detectable element 216 in position relative to the second telescoping member 204. In various embodiments, a detectable element fixation 219 can be provided to hold the detectable element housing 218 relative to the second telescoping member 204. The detectable element 216 is arranged to travel along the axis T with the second telescoping member 204, and can be used to indicate the position of the second telescoping member 204. The detectable element 216 can be a magnet, such as an electromagnet or a permanent magnet. In other embodiments, the detectable element 216 can be an active signal transmitter such as a wireless radio.

[0072] As noted above, the detectable element 216 can be a permanent magnet. For example, a single permanent magnet embodiment of the detectable element 216 can produce a single magnetic field. As described in more detail below, a single permanent magnet or a permanent magnet with a non-repeating magnetic field can be used to consistently determine the position of the first telescoping member 202 relative to the second telescoping member 204. For example, one or more detection elements as described in more detail below can be configured to provide a variable output based on the relative position of the detectable element 216.

[0073] Figure 2The detectable element 216 in the implement defines a field F that makes the detectable element 216 detectable. It should be understood that the field F is determined in part by the detectable element 216 and in part by the associated detector or detection element as described in more detail below. The field F can represent a magnetic field, for example in the case of a permanent magnet implementation of the detectable element 216. The field F can be adjustable, for example between at least two axes. In the illustrated implementation, the field F has a first field axis Fl and a second field axis F2 that is orthogonal to the first field axis Fl. In implementations, the first field axis Fl and the second field axis F2 each represent a field strength and can describe magnetic field lines, for example magnetic field lines of a strength suitable for detection. The first field axis Fl is illustrated as having a greater strength than the second field axis F2. The detectable element 216 can be configured to adjust the magnetic field to achieve a desired strength of the first field axis Fl and the second field axis F2. For example, a plurality of permanent magnets, ferromagnetic elements, and / or non-magnetic elements can be arranged to shape the magnetic field of a permanent magnet implementation of the detectable element 216. It should be understood that other implementations of the detectable element 216 can achieve a desired relationship between the first field axis Fl and the second field axis F2. For example, a wireless radio implementation of the detectable element 216 can be oriented to have a greater range in the first field axis Fl than in the second field axis F2. Further, in some implementations, the second field axis F2 can have a greater strength than the first field axis Fl. In such implementations, the greater strength is aligned with the axial direction relative to the axis T.

[0074] As described above, the detectable element 216 is positionally fixed relative to the second telescoping component 204 and the second telescoping component 204 is movable within the first telescoping component 202. One or more detectors can operate to detect the detectable element 216, for example by detecting the field F, as the second telescoping component 204 moves within the first telescoping component 202 along the axis T. In some implementations, the one or more detectors can be positioned on the first telescoping component 202. In some implementations, the one or more detectors can be positioned on the second telescoping component 204. In some implementations, the one or more detectors can be positioned on the first telescoping component 202 and the second telescoping component 204. In some implementations, the one or more detectors can be positioned on the first telescoping component 202 and the second telescoping component 204 and on the first telescoping component 202 and the second telescoping component 204, respectively. Figure 2In implementations, the first detection element 220 is disposed with the first telescoping member 202. The first detection element 220 can operate to wirelessly detect a position of the detectable element 216. For example, the first detection element 220 can be a magnetometer, a Hall effect sensor, or other sensor configured to generate an output corresponding to a strength of the field F of the detectable element 216. As the detectable element 216 moves relative to the first detection element 220, the corresponding output of the first detection element 220 changes in a predictable manner, which can be continuously measured. Thus, the first detection element 220 can produce an output indicative of the field strength of the field F and the relative position of the detectable element 216 to the first detection element 220. Since the first detection element 220 is fixed in position relative to the first telescoping member 202, and the detectable element 216 is fixed in position relative to the second telescoping member 204, the output of the first detection element 220 can be used to wirelessly indicate the relative position of the first telescoping member 202 to the second telescoping member 204. In some implementations, this relative position can be referred to as a stroke, for example, within a range between a minimum stroke and a maximum stroke.

[0075] Still referring to Figure 2 , the first detection element 220 and any other detection elements can operate to detect the detectable element 216 across one or more other members. For example, the first detection element 220 can be configured to detect the detectable element across the second telescoping member 204. The first detection element 220 is adjustable such that the output generated by the movement of the detectable element 216 on the opposite side of the second telescoping member 204 or any other member disposed therebetween is representative of the relative position of the detectable element 216 to the first detection element 220.

[0076] As described above, the first detection element 220 can be operable to detect the detectable element 216 across a range of relative positions. This range of relative positions of the detectable element 216 to the first detection element 220 can be described with reference to a field reach R. Herein, the field reach R is measured as the detectable range of the field F at a detection plane P. The detection plane P used herein represents a position of the first detection element 220 that is parallel to an axis T along which the first and second elongate members 202, 204 travel relative to one another. The first detection element 220 defines a first detection axis PI that extends from the detection plane P. The illustrated first detection axis PI is orthogonal to the detection plane P and the axis T. However, it will be appreciated that the first detection element 220 can be operable to detect along various axes. In embodiments, the first detection element 220 can be operable to detect along the first detection axis PI and along an orthogonal first detection axis that is parallel to and represented by the detection plane P. In such embodiments, the first detection element 220 can generate an output based on a combination of the detections along the first detection axis PI and along the detection plane P or the orthogonal first detection axis, for example as a vector indicative of an angle. As the detectable element 216 travels relative to the first detection element 220 along the axis T, the resolution along one of the first detection axis PI or the detection plane P can decrease (i.e. the change in detected intensity relative to the change in travel of the detectable element 216 along the axis T can be less). In this example, the output based on a combination of the detections along the first detection axis PI and the detection plane P can ensure that an output indicative of an accurate travel position of the detectable element 216 along the axis T is generated. Although described herein as being generally orthogonal to and parallel to the travel axis T, it will be appreciated that the detection can be performed along any axis at any relative angle to the travel axis T or other detection performed.

[0077] The first detection element 220 can be used to wirelessly detect the position of the detectable element 216 as described above. For example, Figure 2 The first detection element 220 illustrated in FIG. 2B can be operable to detect the position of the detectable element 216 that corresponds to the overlap range of the field reach FR relative to the first detection axis PI. Although the first detection element 220 can still generate an output in response to a position of the detectable element 216 outside of this overlap range of the field reach FR, the resolution can be reduced. It will be appreciated that the strength and shape of the field F and the detection capabilities of the first detection element 220 are adjustable features and can be adjusted to achieve a desired range and resolution. However, as described below, additional detection elements can also be provided.

[0078] Referring still to Figure 2The first detection element 220 may be adjustable to detect the detectable element 216. For example, in some embodiments, the detectable element 216 may provide a peak magnetic field strength of + / -5, 10, 15, or 20 millitalas (mT). Therefore, the first detection element 220 and any additional detection elements may be adjusted to have a sensitivity range of + / -5 mT, + / -25 mT, or + / -50 mT.

[0079] Turn now Figure 3 , Figure 2 A schematic diagram of the position detection device 200 in the second position is shown. Figure 3 The second position depicted in the image represents the first telescopic member 202 relative to the second telescopic member 204 from... Figure 2 The compression movement occurs at the first position shown. When the second telescopic member 204 moves along the stroke axis T in the compression direction C, the detectable element 216 also moves relative to the first detectable element 220. (As shown) Figure 3 As shown, when the field range FR of the detectable element 216 overlaps with the first detection axis P1 of the first detection element 220, the field range FR of the detectable element 216 also overlaps with the second detection axis of the second detection element 222. The second detection element 222 is spaced apart from the first detection element 220. As shown, the second detection element 222 is spaced apart from the first detection element 220 by a first distance D1 along the detection plane P. In this embodiment, the first distance D1 is adjusted to provide a larger range than a single detection element while ensuring that at least one detection element can always operate to generate an output indicating the position of the detectable element 216 based on sensor data. In this embodiment, the first distance D1 is less than the field range FR. In such an embodiment, the effective travel measurement range can be expressed as the first distance D1 plus twice the field range FR, because the detectable element 216 can be detected by at least one of the first detection element 220 or the second detection element 222 throughout this range.

[0080] It should be appreciated that the field of action range FR is an adjustable feature to achieve various objectives. For example, the field of action range FR can be adjusted by increasing the field strength (e.g., by providing a stronger permanent magnet). The field of action range FR can also be adjusted by adjusting the field strength (e.g., by arranging the permanent magnets to increase the first field axis Fl and decrease the second field axis F2). The field of action range FR can also be adjusted by adjusting the detection capabilities of one or more detection elements, such as the first detection element 220. In one example, the field of action range FR is adjusted so that the detectable element 216 is detectable by each of the first detection element 220 and the second detection element 222 in at least one travel position. As noted above, the first distance Dl can be adjusted in accordance with the field of action range FR (e.g., to be less than or equal to the field of action range FR). In various examples, the first distance Dl is at least twenty millimeters (20 mm), thirty millimeters (30 mm), forty millimeters (40 mm), fifty millimeters (50 mm), sixty millimeters (60 mm), seventy millimeters (70 mm), or eighty millimeters (80 mm).

[0081] In the illustrated implementation, the first detection element 220 can be adjusted to detect one position or a range of positions of the detectable element 216, and the second detection element 222 can be adjusted to detect one position or a range of positions of the detectable element 216. As Figure 2 illustrated, the first detection element 220 can be adjusted to detect the illustrated first position of the detectable element 216. The second detection element 222 can be adjusted to detect the second position of the detectable element 216 illustrated in the middle. Figure 3 As noted above, the first detection element 220 can have a range of detection fidelity. For example, the first detection element 220 can have a continuous range of detection fidelity defined by its overlap with the field of action range FR. In another example, the first detection element 220 can have a discontinuous range, e.g., defined by its overlap with the field of action range FR, but excluding a central range where the first field axis Fl overlaps the first detection element 220. In this example, the output from the first detection element 220 can be supplemented or replaced by another detection element, such as the second detection element 222. As Figure 3As shown, at certain positions of the detectable element 216, the first and second detection elements 220, 222 can have the same or similar overlap with the field of action range FR. In this example, a comparison to an expected value can be used to select an output for position determination. For example, a first lookup table can be used to compare expected output values from the first detection element 220, and a second lookup table can be used to compare expected output values from the second detection element 222. It will be appreciated that based on these comparisons, data from one or both of the first and second detection elements 220, 222 can be used for position determination of the detectable element 216.

[0082] Still referring to Figure 3 , the position of the second telescoping component 204 relative to the first telescoping component 202 can also be referred to as an intermediate position. As Figure 3 shown, the detectable element 216 is disposed between the first and second detection elements 220, 222 along the axis T and the detection plane P. In this intermediate position, the detectable element 216 can be detected by each of the first and second detection elements 220, 222. For example, the first and second detection elements 220, 222 can be adjusted to detect this intermediate position of the detectable element 216.

[0083] Now turning to Figure 4 , a schematic view of the position detection apparatus 200 in a third position in Figure 2 and Figure 3 is shown. As Figure 4 shown, the field of action range FR overlaps with a third detection axis P3 of a third detection element 224. As Figure 4 shown, the third detection element 224 is spaced apart from the second detection element 222 along the detection plane P by a second distance D2. In this embodiment, the second distance D2 is adjusted to provide a greater range than the combination of only the first and second detection elements 220, 222 while ensuring that at least one detection element can always operate to generate an output indicative of the position of the detectable element 216 based on sensor data. In embodiments, the second distance D2 is less than the field of action range FR. As shown, the second distance D2 can be similar or equal to the first distance D1 described above. In such embodiments, the effective range of travel measurement can be represented as the first distance D1 plus the second distance D2 plus twice the field of action range FR, as the detectable element 216 can be detected by at least one of the first, second, or third detection elements 220, 222, 224 throughout this range.

[0084] Still referring to Figure 4The third distance D3 is defined between the first detection axis PI of the first detection element 220 and the third detection axis P3 of the third detection element 224. The third distance D3 can be used to define a total detection range. For example, the total detection range can be defined as the third distance D3 plus twice the field range FR, as the detectable element 216 can be detected by at least one of the first detection element 216, the second detection element 222, or the third detection element 224 throughout this range. As noted above, the third distance D3 encompasses the first distance D1 and the second distance D2. In one example, the third distance D3 can be equal to twice the first distance D1 or twice the second distance D2. However, the third distance D3 can be greater than twice the first distance D1 or greater than twice the second distance D1, for example in the case where the first distance D1 and the second distance D2 are not equal.

[0085] As shown in the third position, Figure 4 one or more features can be provided to control the travel of the second telescoping component 204 relative to the first telescoping component 202. For example, a first travel stop 234 can be provided with the first telescoping component 202, and a second travel stop 236 can be provided with the second telescoping component 204. In the example of Figure 4 the first travel stop 234 is configured to physically interface with the second travel stop 236. The first travel stop 234 can be configured as a spring (e.g., a resilient element) in order to control the stop range. The second travel stop 234 can be an end face or other feature provided with the second telescoping component 204, and can be resilient or substantially incompressible. In one example, the resilient implementation of the first travel stop 234 provides a progressively increasing resistance to travel of the second telescoping component 204 as the second telescoping component 204 travels in the compression direction C. Thus, the interaction between the first travel stop 234 and the second travel stop 236 can be used to dampen the compression force or bottoming out force between the first telescoping component 202 and the second telescoping component 204, for example in the suspension implementation of the schematic example of Figures 2 to 4 .

[0086] As noted above with reference to Figure 3 , the first distance D1 can be at least 20 mm, 30 mm, 40 mm, 50 mm, 60 mm, 70 mm, or 80 mm. It will be appreciated that various other sizes of the first distance D1 can also be considered. For example, Figures 2 to 4 in the braking implementation of the schematic, the first distance can be in the range of 2 millimeters (2 mm) to 10 millimeters (10 mm). In Figures 2 to 4In the illustrated embodiment of the schematic view, the second distance can be at least 20 mm, 30 mm, 40 mm, 50 mm, 60 mm, 70 mm, or 80 mm. In this example, the third distance D3 can thus be at least twice these values. Based on the ranges described above (including the twice field range FR), a total detectable range can be described. In embodiments including only the first detection element 220, a range of twice the field range FR can be detected. This range can be at least 40 millimeters (40 mm), 60 millimeters (60 mm), 80 millimeters (80 mm), 100 millimeters (100 mm), 120 millimeters (120 mm), 140 millimeters (140 mm), or 160 millimeters (160 mm) in size. Including additional detection elements can be used to increase the detection range. For example, including the second detection element 222 with the first detection element 220 can increase this range by the size of the first distance D1. Including the third detection element 224 with the first detection element 220 and the second detection element 222 can increase the size of this range by the size of the second distance D2.

[0087] Referring again to Figure 4 , the communication interface 232 is configured to communicate with the first detection element 220. The communication interface 232 can be operable to send a signal in response to a detection by the first detection element 220. In the illustrated example, the communication interface 232 is configured to communicate with the first detection element 220, the second detection element 222, and the third detection element 224. The communication interface 232 can communicate directly with the first detection element 220 or the additional detection elements, or there can be one or more other features between them that communicate. For example, as shown in Figure 4 , the first detection element 220, the second detection element 222, and the third detection element 224 can each be in communication with the processor 228. The processor 228 is configured to process the output from the detection elements 220, 222, 224. The processor 228 in this example is also configured to send an output to the communication interface 232. The output of the processor 228 can be representative of various outputs of the detection elements 220, 222, 224. For example, the processor 228 can generate an output indicative of a location of the detectable element 216 based on an output of at least one of the detection elements 220, 222, 224.

[0088] The processor 228 can also send an output to the detection elements 220, 222, 224. For example, the processor 228 can send an output to at least one of the detection elements 220, 222, 224 to adjust a detection quality and / or power. In embodiments, the processor 228 sends an output to at least one of the detection elements 220, 222, 224 to increase a detection power based on a detected noise level or a flag output from at least one of the detection elements 220, 222, 224.

[0089] The processor 228 can be configured in various ways to communicate between at least one of the detection elements 220, 222, 224 and the communication interface 232. In some examples, the communication interface 232 can be integrated with the processor 228, for example on the same printed circuit board. For example, the processor 228 can be a system-on-a-chip processor. Thus, the processor 228 and the communication interface 232 can be configured to process output from at least one of the detection elements 220, 222, 224 and send the output to another device, such as a portable device, a head unit, or another bicycle component. In various implementations, the processor 228 can be one of the nRF series of processors from Nordic Semiconductor®. For example, the processor 228 can be one of the nRF52833, nRF52840, or nRF54L15 from Nordic Semiconductor®.

[0090] The communication interface 232 can be wired or wireless. As noted above, the communication interface 232 can be connected to the processor 228 by wire or otherwise integrated with the processor 228. The communication interface 232 can also be connected to at least one of the detection elements 220, 222, 224 by wire. Additionally or alternatively, the communication interface 232 can include a wireless radio. For example, the communication interface 232 can include at least one of a Bluetooth®, mesh network, Thread, LoRa, NFC, ANT, 802.15.4, 2.4 GHz, or Zigbee compatible radio for transmitting and / or receiving signals. It will be appreciated that the communication interface 232 and / or the processor 228 can be configured to transmit encrypted signals and can employ a count value or rolling code to further secure communications.

[0091] Still referring to Figure 4 The power source 226 is disposed in communication with at least one of the detection elements 220, 222, 224. As shown, the power source 226 is in communication with and provides power to the processor 228, the communication interface 232, the first detection element 220, the second detection element 222, and the third detection element 224. The power source 226 can be replaceable and / or rechargeable. In one example, the power source 226 is at least one button cell or coin cell battery. For example, the power source 226 can be a CR1620, CR1632, CR2032, CR1025, or CR2477 button cell battery. The power source 226 can be removable, for example without tools. As shown, the power source 226 is disposed in the housing 202. In other examples, the power source 226 can be disposed in another location, for example in the handlebar stem 104, the handlebar 102, or the head unit 106. Figure 4As shown, power supply 226 can be housed in one or more structures. For example, the illustrated embodiment provides a detection housing 230 for housing power supply 226. In this example, the detection housing 230 houses processor 228, communication interface 232, first detection element 220, second detection element 222, and third detection element 224.

[0092] As described above, one or more electrical components may be disposed within the detection housing 230. For example, the power supply 226 may be disposed removably or non-removably within the detection housing 230. The power supply 226 may also be disposed outside the detection housing 230. For example, the power supply 226 may be removably attached to the outside of the detection housing 230.

[0093] Turn now Figure 5 An example is shown. Figures 2 to 4 The graph shows the output of the position detection device 200. Figure 5 The graph depicts various trajectories measured along the x-axis 580 and y-axis 590. The x-axis 580 represents the travel position of the second telescopic member 204 relative to the first telescopic member 202. For example, the x-axis 580 could be a linear scale in millimeters. The y-axis 590 represents the detector output, as shown in the reference above. Figures 2 to 4 The outputs from the first detection element 220 and the second detection element 222 are described. Therefore, the y-axis can represent the magnetometer reading, for example, in millitalas (mT).

[0094] exist Figure 5 The graph shows a first trajectory 510, a second trajectory 520, a third trajectory 530, and a fourth trajectory 540. The first trajectory 510 represents a first output from the first detection element, and the second trajectory 520 represents a second output from the first detection element. (Refer to...) Figure 5 The first detection element described can be any detection element; the above reference will be used below. Figures 2 to 4 The first detection element 220 is described as an example. Figure 5 As shown in the graph, the first trajectory 510 describes the maximum output 502 of the first trajectory, which can be an absolute maximum output or a local maximum output. (Referring to the above...) Figures 2 to 4 In the example of the magnetometer described, Figure 5 The maximum output of 502 for the first trajectory represents the maximum magnetometer reading.

[0095] Still refer to Figure 5 The second trajectory 520 describes the maximum output 503 of the second trajectory, which can be an absolute maximum output or a local maximum output. Using the above... Figures 2 to 4In the example, the maximum output 503 of the second track represents the maximum magnetometer reading. The maximum output 502 of the first track and the maximum output 503 of the second track can represent different maximum outputs of the same magnetometer. For example, a multi-axis magnetometer can be used, where the first track 510 represents the output of the first axis of the multi-axis magnetometer, and the second track 520 represents the output of the second axis of the multi-axis magnetometer. The first and second axes can have any angular relationship, but in this example, they will be described as having an orthogonal relationship (specifically, a perpendicular relationship). For example, the first track 510 can represent an axial magnetometer reading (i.e., parallel to...). Figures 2 to 4 The detection plane P), and the second trajectory 520 can represent the radial magnetometer reading (i.e., perpendicular to the detection plane P, for example along the detection plane P). Figures 2 to 4 The first detection axis P1 in the middle.

[0096] Figure 5 The second trajectory 520 also describes the second trajectory minimum output 501. Continuing with the above multi-axis magnetometer example, the second trajectory minimum output 501 represents the above reference... Figures 2 to 4 The description refers to the local minimum or absolute minimum of the radial magnetometer reading of the first detection element 220. Therefore, the second trajectory 520 describes both the minimum output 501 and the maximum output 503 of the second trajectory. From Figure 5 As can be seen from the graph, the second trajectory 520 can be described as having a first peak output corresponding to the minimum output 501 of the second trajectory, and a second peak output corresponding to the maximum output 503 of the second trajectory; while the first trajectory 510 can be described as having a single peak output corresponding to the maximum output 502 of the first trajectory. As described above, in the example of axial magnetometer readings, the peak output of the second trajectory 520 represents parallel to... Figures 2 to 4 The peak magnetometer output is measured on the detection plane P; while in the example of the radial magnetometer, the peak output of the first trajectory 510 represents the peak output along the plane P. Figures 2 to 4 The peak magnetometer output is measured on the first detection axis P1.

[0097] exist Figure 5 In this process, the first peak-to-peak distance D7 is measured between the minimum output 501 of the second trajectory and the maximum output 502 of the first trajectory. The second peak-to-peak distance D8 is measured between the maximum output 502 of the first trajectory and the maximum output 503 of the second trajectory. The combination of the first peak-to-peak distance D7 and the second peak-to-peak distance D8 can be collectively referred to as the central region of the first magnetometer. Within the entire range of the combination of the first peak-to-peak distance D7 and the second peak-to-peak distance D8, the axial and radial components of the first magnetometer cooperate to provide reliable data based on relatively strong magnetic field readings. Near each peak, for a given travel along the x-axis 580, there is a high rate of change along the y-axis 590. This will be referred to below. Figure 6In more detail, the first trajectory 510 and the second trajectory 520 can be combined (e.g., to represent angles) to provide a relatively consistent rate of change along the y-axis 590 over the entire range of the first peak-to-peak distance D7 and the second peak-to-peak distance D8. Thus, the first peak-to-peak distance D7 and the second peak-to-peak distance D8 can represent a first magnetometer (such as the referenced above). Figures 2 to 4 The high-fidelity magnetometer reading area of ​​the first detection element 220 described.

[0098] Still refer to Figure 5 The third trajectory 530 and the fourth trajectory 540 can together describe the axial and radial magnetometer readings, for example, as described above. Figures 2 to 4 As described in the second detection element 222. Figure 5 As shown in the graph, the third trajectory 520 describes the maximum output 505 of the third trajectory, which can be an absolute maximum output or a local maximum output. (Referring to the above...) Figures 2 to 4 In the example of the magnetometer described, Figure 5 The third track maximum output 505 represents the maximum magnetometer reading. The fourth track 540 describes the fourth track maximum output 506, which can be an absolute maximum output or a local maximum output. Using the above... Figures 2 to 4 In the example, the maximum output 506 of the fourth track represents the maximum magnetometer reading. The maximum output 505 of the third track and the maximum output 506 of the fourth track can represent different maximum outputs of the same magnetometer. For example, a multi-axis magnetometer can be used, where the third track 530 represents the output of the first axis of the multi-axis magnetometer, and the fourth track 540 represents the output of the second axis of the multi-axis magnetometer. The first and second axes can have any angular relationship, but in this example, they will be described as having an orthogonal relationship (specifically, a perpendicular relationship). For example, the third track 530 can represent an axial magnetometer reading (i.e., parallel to...). Figures 2 to 4 The detection plane P), and the fourth trajectory 540 can represent the radial magnetometer reading (i.e., perpendicular to the detection plane P, for example along the detection plane P). Figures 2 to 4 The second detection axis P2 in the middle.

[0099] Figure 5 The fourth trajectory 540 also describes the minimum output 504 of the fourth trajectory. Continuing with the above multi-axis magnetometer example, the minimum output 504 of the fourth trajectory represents the aforementioned reference... Figures 2 to 4 The local minimum or absolute minimum value of the radial magnetometer reading of the second detection element 222 is described. Therefore, the fourth trajectory 540 describes both the minimum output 504 and the maximum output 506 of the fourth trajectory. From Figure 5As can be seen in the plot of FIG. 5, the fourth trace 540 can be described as having a first peak output corresponding to the fourth trace minimum output 504, and a second peak output corresponding to the fourth trace maximum output 506; while the third trace 530 can be described as having a single peak output corresponding to the third trace maximum output 505. As described above, in the example of axial magnetometer readings, the peak output of the fourth trace 540 represents a peak magnetometer output measured parallel to the detection plane P; while in the example of a radial magnetometer, the peak output of the third trace 530 represents a peak magnetometer output measured along the second detection axis P2. Figures 2 to 4 Figures 2 to 4 In the example of an axial magnetometer, the peak output of the third trace 530 represents a peak magnetometer output measured parallel to the detection plane P; while in the example of a radial magnetometer, the peak output of the fourth trace 540 represents a peak magnetometer output measured along the second detection axis P2.

[0100] In the example of an axial magnetometer, the peak output of the third trace 530 represents a peak magnetometer output measured parallel to the detection plane P; while in the example of a radial magnetometer, the peak output of the fourth trace 540 represents a peak magnetometer output measured along the second detection axis P2. Figure 5 In the example of an axial magnetometer, the peak output of the third trace 530 represents a peak magnetometer output measured parallel to the detection plane P; while in the example of a radial magnetometer, the peak output of the fourth trace 540 represents a peak magnetometer output measured along the second detection axis P2. Figure 6 As will be described in greater detail below with respect to FIG. 6, the third trace 530 and the fourth trace 540 can combine (e.g., to represent an angle) to provide a relatively consistent rate of change along the y-axis 590 throughout the range of the third peak-to-peak distance D9 and the fourth peak-to-peak distance D10. Thus, the third peak-to-peak distance D9 and the fourth peak-to-peak distance D10 can together represent a high-fidelity magnetometer reading region of the second magnetometer (such as the second detection element 222 described above with respect to FIG. 2). Figures 2 to 4

[0101] Still referring to FIG. 5, the first magnetometer center region defined by the first peak-to-peak distance D7 and the second peak-to-peak distance D8 can be spaced apart from the second magnetometer center region defined by the third peak-to-peak distance D9 and the fourth peak-to-peak distance D10. This spacing can represent the spacing of the first magnetometer and the second magnetometer, for example in the example described above with respect to FIG. 2. Figure 5 Figures 2 to 4 ​​​In the case of the first detection element 220 and the second detection element 222 described, the first spacing D4 can be defined between the maximum output of the first trajectory 502 and the maximum output of the third trajectory 505. The second spacing D5 can be defined between the maximum output of the second trajectory 503 and the maximum output of the fourth trajectory 506. The third spacing D6 can be defined between the minimum output of the second trajectory 501 and the minimum output of the fourth trajectory 504. The magnitudes of each of the first spacing D4, the second spacing D5, and the third spacing D6 can be equal, for example, when the magnitudes of the first peak-to-peak distance D7, the second peak-to-peak distance D8, the third peak-to-peak distance D9, and the fourth peak-to-peak distance D10 are equal. It should also be understood that these relative distances can be adjusted based on sensor arrangement and / or sensitivity.

[0102] The first spacing D4, the second spacing D5, and the third spacing D6 together define the magnetometer overlap region, in which the outputs of the first and second magnetometers can be combined. Specifically, the region defined between the maximum output 503 of the second trajectory and the minimum output 504 of the fourth trajectory can be used to define the distance between the most recent peak outputs of the individual magnetometers, which can be spaced out as shown or can overlap. In one example, this distance between the most recent peak outputs can be adjusted to maximize the distance between the individual magnetometers while ensuring reliable position data throughout this range.

[0103] exist Figure 5 In the example, the range between the origin at y-axis 590 and the maximum travel 509 represents the total travel range along x-axis 580. Within this range, each magnetometer can have a defined effective range. For example, magnetometer data may be particularly useful in the range near its peak. As shown, the first magnetometer data represented by the first track 510 and the second track 520 can define a first magnetometer range D11, which lies between the origin at y-axis 590 and the first magnetometer transition point 508. The first magnetometer transition point 508 does not necessarily represent a point where the first magnetometer reading is no longer used or preferred, but can represent a point beyond which only the second magnetometer reading is used. The second magnetometer data represented by the third track 530 and the fourth track 540 can define a second magnetometer range D12, which lies between the second magnetometer transition point 507 and the maximum travel 509. The second magnetometer transition point 507 does not necessarily represent a point where the second magnetometer reading is no longer used or preferred, but rather a point beyond which only the first magnetometer reading is used. It should be understood that the described range is adjustable and can overlap to any desired degree.

[0104] exist Figure 5In this context, an overlap range D13 is defined between the second magnetometer transition point 507 and the first magnetometer transition point 508. The overlap range D13 indicates a range within which each of the first and second magnetometers (e.g., ...) Figures 2 to 4 Both the first detection element 220 and the second detection element 222 can provide useful position data. It should be understood that the example can be adjusted so that all travel is achieved within the overlapping range D13, or as... Figure 5 As shown, useful readings can be easily obtained even outside the overlapping range D13 by using data from the first and second magnetometers individually.

[0105] Turn now Figure 6 Another example is shown. Figures 2 to 4 The graph shows the output of the position detection device. Figure 6 The description of the curve will continue as described above. Figure 5 The example graph shown is illustrated. Specifically, a reference of the same size along the axis shown can be used. Figures 2 to 4 The implementation method. However, it should be understood that, Figure 6 The graph can represent various values ​​and sizes, which represent other examples considered in this article. Figure 6 The graph includes an x-axis of 680 and a y-axis of 690. The x-axis of 680 represents the travel position of the second telescopic component 204 relative to the first telescopic component 202, and the y-axis of 690 represents the detector output.

[0106] exist Figure 6 The diagram illustrates a fifth track 615 and a sixth track 635. The fifth track 615 represents first magnetometer data, and the sixth track 635 represents second magnetometer data. For example, the fifth track 615 can describe... Figure 5 The relationship between the first trajectory 510 and the second trajectory 520 is, for example, an angular relationship. Referring to the multi-axis magnetometer example above, the fifth trajectory 615 represents an angle calculated based on orthogonal components (e.g., axial and radial components). In this example, Figure 6 The sixth trajectory 635 can describe Figure 5 The relationship between the third trajectory 530 and the fourth trajectory shown is, for example, an angular relationship. Referring again to the multi-axis magnetometer example above, the sixth trajectory 635 represents an angle calculated based on orthogonal components (e.g., axial and radial components).

[0107] from Figure 6As can be seen, the fifth trajectory 615 provides smooth and reliable position data at least between the origin at y-axis 690 and the first magnetometer transition point 508. Between the first magnetometer transition point 508 and the maximum travel 509, the fifth trajectory 615 may provide relatively unpredictable position data. In this example, data from the sixth trajectory 635 provides smooth and reliable position data within this range. The sixth trajectory 635 provides smooth and reliable data at least between the second magnetometer transition point 507 and the maximum travel 509. Between the origin at y-axis 690 and the second magnetometer transition point 507, the sixth trajectory 635 may provide relatively unpredictable position data. As mentioned above, the fifth trajectory 615 provides smooth and reliable position data within this range. Therefore, smooth and reliable position data can be ensured throughout the entire range from the origin at y-axis 690 to the maximum travel 509.

[0108] Turn now Figure 7 A perspective view of the front fork 700 is provided. The front fork 700 can be used with position detection devices described elsewhere in this document, such as those mentioned above. Figures 2 to 4 The position detection device 200 is described. Figure 7 The fork 700 shown typically includes a seat tube 702, which is used to attach to the bicycle frame (e.g., Figure 1 The frame 102). The seat tube 702 is connected to the fork crown assembly 704. The fork crown assembly 704 transmits force to the seat tube between other suspension components. For example, the fork crown assembly 704 transmits steering torque input from the rider to the wheel connected to the wheel mount 710 (i.e., the wheel). Figure 1 The front wheel 104 is connected to the fork crown assembly 704, and the suspension forces are transmitted to the rider via the seat tube 702. The upper assembly 706 is connected to the crown assembly 704. The upper assembly 706 may include one or more top tubes, such as... Figure 7 The fork is provided with a dual upper tube structure. In other examples, a single tube structure may be provided. It should also be understood that although the upper component 706 and the crown assembly 704 are shown as separate parts, they may be formed at least partially integrally. For example, an inverted or overturned fork configuration may have an integral crown and upper component (not shown). The lower component 708 is movable relative to the upper component 706. Each of the lower component 708 and the upper component 706 may be individually referred to as a suspension element. The relative movement of the lower component 708 and the upper component 706 is used to provide the suspension function of the fork 700. This relative movement of the lower component 708 and the upper component 706 may be along... Figure 7 The tube-in-tube structure shown can proceed along an axis, or it can follow different paths, for example, by using various linkages to control movement. Although Figure 7The example shows the upper component 706 housed within the lower component 708, but it should also be understood that, as in the case of a reverse fork, the lower component 708 can also be housed within the upper component 706.

[0109] Still refer to Figure 7 The fork 700 also includes a damper portion 712 and a spring portion 714. The spring portion 714 may be an air spring, a metal coil spring, or other spring construction and is configured to support the rider's weight. The damper portion 712 is configured to control the movement of the spring portion 714 and is adjustable in various aspects. Although the damper portion 712 and the spring portion 714 are shown in different legs of the fork 700, it should be understood that the damper portion 712 and the spring portion 714 may also be combined in the same leg of the fork 700, whether in a single leg or in two legs. A brake mounting portion 716 is also provided for accommodating a brake (such as a mechanical or hydraulic brake caliper (not shown)) to act on a brake rotor (not shown). The brake mounting portion 716 may be provided on a single leg as shown, located to one side of the damper portion 712 or the spring portion 714. A second brake mounting portion (not shown) may also be provided on opposite legs of the fork 700.

[0110] Figure 7 A first position detection housing 718 and a second position detection housing 720 are also depicted. The position detection housings 718 and 720 can be configured as other examples as described herein, such as those referenced. Figures 2 to 4 Examples of those and position detection devices 200. Figure 7 The section lines 8-8, 10-10, 11-11, and 12-12 shown schematically depict a portion of the fork, which will be discussed below. Figures 8 to 13 Various implementations of this section are described.

[0111] Turn now Figure 8 Provided along Figure 7 A first example of a cross-sectional view of the position detection device 800 intercepted by section line 8-8 in the schematic diagram. (Refer to...) Figure 8 The described position detection device 800 includes a first fork 802 and a second fork 804. As shown in the figure, the first fork 802 can be a lower fork, for example, refer to Figure 7 The lower component 708 is described as part of the lower component. The second fork 804 can be the upper fork, for example, see reference. Figure 7 This is part of the upper component 706 as described. Figure 8 The portion depicted in the diagram can generally be referred to as the overlapping region, in which the first fork 802 and the second fork overlap axially relative to the damper axis Q. Figure 8The first prong 802 and the second prong 804 in the example are each generally tubular in configuration. The first prong 802, also referred to as a first tube, defines a first prong volume or a first tube volume. The second prong 804, also referred to as a second tube, defines a second prong volume or a second tube volume. As shown, the second prong 804 is at least partially disposed within the volume defined by the first prong 802. As described above with respect to the first telescoping member 202 and the second telescoping member 204 of Figures 2 to 4 , the second prong 804 is configured to telescopically translate relative to the first prong 802. For example, as shown in Figure 8 , the second prong 804 can translate relative to the first prong 802 along a damper axis Q. The damper axis Q can generally describe the axis of translation, for example as described with respect to the axis T described in Figures 2 to 4 .

[0112] Still referring to Figure 8 , a detectable element 816 is provided. As described elsewhere herein, the detectable element 816 can have various configurations, including a permanent magnet configuration that generates a magnetic field. The detectable element 816 can also be referred to as a field generating element. The detectable element 816 can be at least partially disposed in the volume defined by the first prong 802. For example, Figure 8 , the detectable element 816 is disposed in the volume defined by the first prong 802 and in the volume defined by the second prong 804.

[0113] The detectable element 816 can be secured relative to the second prong 804 by various configurations. For example, Figure 8 , the detectable element 816 is disposed in a detectable element housing 818 and is secured at least by a detectable element securing device 819. The detectable element securing device 819 can be a resilient element, a resilient retaining ring, an adhesive, or various other securing devices. In the present example, a detectable element retainer 838 can also partially retain the detectable element 816 relative to the second prong 804. The detectable element retainer 838 can be a resilient element or a relatively rigid element, and can be further configured to provide alignment. For example, the detectable element retainer 838 shown can limit movement of the second prong 804 relative to the detectable element housing 818 in a radial direction.

[0114] As Figure 8As shown, the detectable element 816 can also be fixed relative to the body 842. The body 842 can also be referred to as a damper body that at least partially controls the damping fluid. The body 842 is fixed relative to the second fork leg 804, and thus is able to move with the second fork leg 804 along the damper axis Q. The rod 840 is at least partially movable within the body 842. For example, the rod 840 can move through the damping fluid within the body 842 to control the relative movement of the first fork leg 802 and the second fork leg 804. The rod 840 is fixed relative to the first fork leg 802.

[0115] At least one detector can be provided for detecting the magnetic field of the detectable element 816. For example, as shown, a first detection element 820 and a second detection element 822 are provided. The first detection element 820 and the second detection element 822 can be provided external to the volume defined by the first fork leg 802 and the volume defined by the second fork leg 804. For example, the first detection element 820 and the second detection element 822 shown are provided in a detection housing 830. The detection housing shown is provided on the outside of the first fork leg 802. It is also contemplated that the detection housing can be integrated into the first fork leg 802, for example in a detection housing cavity (not shown) of the first fork leg 802. As shown, the first detection element 820 and the second detection element 822 can generally be described as being provided externally, while the detectable element can generally be described as being provided internally. Figure 8 Figure 8 As shown, the first detection element 820 and the second detection element 822 can generally be described as being provided externally, while the detectable element can generally be described as being provided internally.

[0116] Still referring to the example of Figure 8 , the first detection element 820 and / or the second detection element 822 are shown to be located on a side of one or more of the elements opposite the detectable element 816. For example, the first detection element 820 and the second detection element 822 can each be described as being located on a side of the first fork leg 802 opposite the detectable element 816. The first detection element 820 and the second detection element 822 can each also be described as being located on a side of the second fork leg 804 opposite the detectable element 816. It should be understood that the first detection element 820 and / or the second detection element 822 can be provided in a separate detection housing 830, or integrated with one or more of the elements, and still be able to detect the detectable element 816 across one or more of the elements. For example, the first detection element 820 and / or the second detection element 820 can be integrally housed with the first fork leg 802, and can be operable to detect the position of the detectable element 816 across the second fork leg 804.

[0117] ​The first detection element 820 and the second detection element 822 communicate with the processor 828 and the communication interface 832, and receive power from the power supply 826. It should be understood that the configuration of the first detection element 820, the second detection element 822, and related elements can generally be described with reference to related elements in other examples described herein. For example, the configuration of the first detection element 820, the second detection element 822, and related elements can generally be described with reference to... Figures 2 to 4 The first detection element 220 and the second detection element 222 are described in this way, and these descriptions can also be applied to the following references. Figures 9 to 14 Other embodiments described. Although Figure 8 The embodiment shown has a first detection element 820 and a second detection element 822, but it should be understood that any number of detection elements can be provided. For example, only the first detection element 820 can be provided, or a third detection element (not shown) or more detection elements (not shown) can be provided.

[0118] Turn now Figure 9 Provided along Figure 7 An example of a cross-sectional view of the detectable element assembly 900, taken by section line 8-8 in the schematic diagram. The detectable element assembly 900 can generally be used with other examples provided herein, such as with reference to Figure 8 Used together with the described position detection device 800. Figure 9 The example provides a detectable element 916, which is housed in a detectable element housing 918 and secured at least partially by at least one detectable element retaining device. As shown, a plurality of detectable element retaining devices 919 are provided. The plurality of detectable element retaining devices 919 can be threaded fasteners. For example, the clamshell construction of the detectable element housing 918 can be held together by the plurality of detectable element retaining devices 919.

[0119] Figure 9 The detectable element 916 is fixed relative to the body 942. For example, the detectable element 916 may be held between the body 942 and the detectable element housing 918. The body 942 may be configured as described above. Figure 8 The damper body is described. For example... Figure 9 As shown, the body 942 includes a body opening 943, for example, for receiving a rod or other damping member (e.g., see reference 943). Figure 8 The described rod is 840. Figure 9 The body 942 depicted also includes a body attachment interface 941. The body attachment interface 941 can be used to position various other components. For example, the body attachment interface can interface with a rod sealing assembly (not shown) to seal one or more damper components.

[0120] Turn now Figure 10, providing for position detection along Figure 7 A second example of a cross-sectional view of a position detection device 1000 taken along the cut line 10-10 of the schematic view is provided. It should be understood that the position detection device 1000 can generally apply any of the features or relationships described elsewhere herein with reference to other example position detection devices and related elements. The position detection device 1000 can generally be configured to be coupled with an air spring that is translatable along a spring axis S. The spring axis S can generally represent an axis along which components of the position detection device 1000 are relatively translatable, and can generally conform to the description provided with reference to the spring axis T in Figures 2 to 4 Figure 10 As shown, the position detection device 1000 can include a piston 1044 with a piston seal 1046 for sealing an air spring. For example, the piston seal 1046 can interface with an inner surface of the second fork leg 1004 to seal the air spring therein. The second fork leg 1004 can be movable relative to the first fork leg 1002 along the spring axis S to compress or extend the air spring.

[0121] Figure 10 A detectable element 1016 is also provided that is secured within the second fork leg 1004. The illustrated detectable element 1016 is disposed in a detectable element housing 1018 with a detectable element securing device 1019. The detectable element housing 1018 can generally contain the detectable element 1016. The detectable element securing device 1019 can be a resilient element. For example, the detectable element securing device 1019 can be configured to cushion or absorb impacts to the detectable element 1016.

[0122] A body 1042 is also provided to at least partially retain Figure 10 the detectable element 1016. The body 1042 can be referred to as a spacer. The illustrated body 1042 maintains the detectable element 1016 spaced apart from an end of the second fork leg 1004 in the compression direction C. Thus, the body 1042 can be used to achieve a desired position of the detectable element and / or to isolate the detectable element 1016 from any bottoming out impacts. The body 1042 is retained in the second fork leg 1004 by a detectable element retainer 1038. The illustrated detectable element retainer 1038 can be a resilient snap ring or other suitable retaining element to retain the body 1042, the detectable element 1016, and other related elements.

[0123] Figure 10 The illustrated example also includes a rod 1040 attached to the piston 1044. The rod 1040 can move with the first fork leg 1002 relative to the detectable element 1016 and the second fork leg 1004. Thus, movement of the detectable element 1016 relative to the first fork leg 1002 can be used to determine movement of the piston 1044 relative to the second fork leg 1004, and in turn, compression and extension of the air spring.​

[0124] One or more detection elements can be set to detect the position of the detectable element 1016. For example, Figure 10 A first detection element 1020 and a second detection element 1022 are provided, which communicate with the processor 1028 and the communication interface 1032, and receive power from the power supply 1026. The first detection element 1020 and the second detection element 1022 are typically disposed outside the air spring surrounded by the first fork 1002 and the second fork 1004. Figure 10 As shown in the example, the first detection element 1020 and the second detection element 1022 are enclosed in a detection housing 1030 disposed on the first fork 1002. The first detection element 1020 and the second detection element are operable to detect the position of the detectable element across the detection housing 1030, the first fork 1002 and the second fork 1004.

[0125] Turn now Figure 11 Provided along Figure 7 The schematic diagram shows a third example of a cross-sectional view of the position detection device 1100, taken by section line 11-11. It should be understood that the position detection device 1100 can generally apply any features or relationships described elsewhere in this document with reference to other example position detection devices and related elements. Figure 11 As shown, the position detection device 1100 is provided with a braking and detection combination housing 1130. The braking and detection combination housing 1130 is configured to be fixed relative to the first fork 1102 and movable relative to the second fork 1104. Although the braking and detection combination housing 1130 in this example is configured to be connected to an air spring and at least partially translatable along the spring axis S, it should be understood that this example can also be used in damper implementations of the position detection device.

[0126] Figure 11The example provides a detectable element 1116 located within a detectable element housing 1118. As shown, the detectable element 1118 is attached to a body 1142, which in turn is positioned relative to a second fork 1104. The detectable element 1116 is enclosed within the detectable element housing 1118, which is at least partially positioned by a detectable element retaining device 1119. The size and shape of the detectable element retaining device 1119 may be configured to secure the detectable element housing 1118 relative to the second fork 1102, for example, by an interference fit. The detectable element retaining device 1119 may be resilient to allow for an interference fit and / or cushioning of the detectable element 1116 against vibration. A detectable element limiter 1138, also referred to as a spacer, is provided, which may operate as described in other air spring examples herein. For example, the detectable element limiter 1138 may be... Figure 11 The bottoming limiter 1148 shown in the example interacts to define the bottoming position of the position detection device 1100.

[0127] Still refer to Figure 11 The rod 1140 is connected to the first fork 1102. The rod 1140 may be rigidly connected to the first fork 1102, or at least partially isolated from it. For example, the rod 1140 may be vibrationally isolated from the first fork 1102 by one or more isolation features. In this example, the first isolator 1150 is positioned below the rod 1140 in the compression direction C, and the second isolator 1152 is positioned above the rod 1140 in the compression direction C. The first isolator 1150 and the second isolator 1152 may cooperate to dampen or otherwise control energy input from the suspension before it is transferred to the rod 1140. It should be understood that relative movement of the first fork 1102 and the second fork 1104 along the spring axis S will still occur regardless of the input to the first isolator 1150 and the second isolator 1152. Therefore, the position detection device 1100 described herein can be operated to measure the positional change of the second fork 1104 relative to the first fork 1102 under the action of the first isolator 1150 and / or the second isolator 1152.

[0128] Despite Figure 11 While not visible in the view, various other components of the position detection device 1100 can be housed there. For example, the braking and detection combination housing 1130 described above can accommodate various detectors and related components. In one example, the braking and detection combination housing 1130 typically houses components similar to those described above. Figures 2 to 4 The described component arrangement structure is as shown in the detection housing 230. For example... Figure 11As shown, the first detection axis P1 and the second detection axis P2 extending from the detection plane P indicate a detection element (not shown) operable to measure the position of the detectable element 1116.

[0129] Turn now Figure 12 Provided along Figure 7 The fourth example of a cross-sectional view of the position detection device 1200, taken by section line 12-12 in the schematic diagram. It should be understood that the position detection device 1200 can generally apply any features or relationships described elsewhere in this document with reference to other example position detection devices and related elements. For example... Figure 12 As shown, the various components of the position detection device 1200 can be translated along the damper axis Q. For example, the first fork 1202 can move relative to the second fork 1204 along the damper axis Q. The second fork 1204 can be translated relative to the first fork 1202 in the compression direction C within a certain stroke range until the stroke is stopped by the bottoming limiter 1248.

[0130] exist Figure 12 In the example, the detectable element 1216 is fixed in position relative to the second fork 1204. The detectable element 1216 can be directly attached to the second fork 1204, for example, by adhesive. Alternatively, as Figure 12 As shown in the example, the detectable element 1216 may be disposed within the detectable element housing 1218. The detectable element housing 1218 is then attached to the second fork 1204. In this example, a detectable element retaining device 1219 is provided for securing the detectable element housing 1218 relative to the second fork 1204. The detectable element retaining device 1219 may be an integral part of the second fork 1204, for example, axially projecting inward relative to the damper axis Q. The detectable element retaining device 1219 may also be configured as a removable element, such as a resilient retaining ring or an O-ring.

[0131] In this example, the second fork 1204 is movable along the damping axis Q relative to the rod 1240 attached to the first fork 1202. The rod 1240 can move at least partially through a body 1242, which may also be referred to as an air spring body. The rod 1240 can be at least partially isolated from the first fork 1202. For example, the rod 1240 can be elastically supported and / or damped relative to the first fork 1202. Figure 12 As shown in the example, isolator 1252 can be configured to isolate rod 1240 from impacts or other forces applied to first fork 1202. As illustrated, isolator 1252 can operate to absorb forces on first fork 1202 along the compression direction C and in the opposite direction of compression C in the force transmission path to rod 1240. Isolator 1252 can be configured as multiple elements, such as... Figure 11The first isolator 1150 and the second isolator 1152 are shown in the diagram. Figure 12 In the example, isolator 1252 is configured as a single component that at least partially retains rod 1240 to control its movement in the compression direction C and in the direction opposite to the compression direction C.

[0132] Still refer to Figure 12 A detection housing 1230 is disposed outside the first fork 1202. The detection housing 1230 typically houses one or more detectors for detecting the position of a detectable element 1216 inside the first fork 1202. In this example, the detection housing 1230 houses a first detection element 1220 and a second detection element 1222, each communicating with a processor 1228, a power supply 1226, and a communication interface 1232. The communication interface 1232 can be wired or wireless and can be used to transmit data and / or command signals. For example, the communication interface 1232 can be used to transmit data indicating position and / or to transmit command signals from processed position data, which can be operated to command changes in suspension damping control, suspension spring control, or control of one or more other bicycle components.

[0133] Turn now Figure 13 Provided Figure 12 A partial exploded view of the detectable element assembly 1299 of the mid-position detection device 1200. The detectable element assembly 1299 can generally be described as the detectable element 1216 and related elements fixed relative to the detectable element 1216. For example... Figure 13 As shown, the detectable element 1216 can be assembled together with the detectable element housing 1218 along the assembly axis G. The detectable element housing 1218 has a detectable element cavity 1254, the size and shape of which are configured to accommodate the detectable element 1216. The detectable element gap 1256 can be configured as a feature corresponding to the detectable element 1216. In this example, the detectable element gap 1256 is disposed in the second fork 1204. The detectable element gap 1256 can cooperate with the detectable element housing 1218 to accommodate the detectable element 1216. The detectable element gap 1256 can also be used to reduce the wall thickness of the second fork 1204, for example, to facilitate the transmission of the field of the detectable element 1216 across the second fork 1204. In one example, the detectable element gap 1256 can be a broaching feature in the second fork 1204.

[0134] Still refer to Figure 13 The second fork 1204 is provided with a limiter groove 1239. The limiter groove 1239 can be used to control the impact force. For example, the limiter groove 1239 can be configured to... (The sentence is incomplete and requires further context to be translated accurately.) Figure 12The described bottoming limiter 1248 deflects or otherwise absorbs bottoming force upon contact. The shape and size of the limiter recess 1239 are configured to accommodate the detectable element limiter 1238. The detectable element limiter 1238 can be any suitable feature for holding the detectable element 1216 relative to the second fork 1204. Figure 13 As shown, the detectable element limiter 1238 may be a resilient retaining ring that can be removed for easy disassembly or maintenance.

[0135] Turn now Figure 14 A perspective view of the position detection device 1400 is provided. The position detection device 1400 can be used in various bicycle parts, such as... Figure 7 700 front fork Figure 1 108 or Figure 1 Rear suspension component 136. Figure 14 Position detection devices typically include features described in relation to other embodiments, such as those referenced above. Figures 2 to 4 Features of the described position detection device 200. For example... Figure 14 As shown, the position detection device 1400 includes a detection housing 1430. The detection housing 1430 can be used to define the internal space of the position detection device 1400; for example, components can be housed within the internal space of the detection housing 1430. As shown, the detection housing 1430 is provided independently of any other bicycle component, but it should be understood that the detection housing 1430 can be used with various bicycle components (e.g., ...). Figure 7 700 front fork Figure 1 108 or Figure 1 The rear suspension components 136 are integrated.

[0136] Still refer to Figure 14 The position detection device 1400 also includes a housing mount 1431. The housing mount 1431 is fixed to the detection housing 1430, for example, by one or more fasteners (not shown) and / or adhesives. The housing mount 1431 may cooperate with the detection housing 1430 to seal the internal space defined by the detection housing 1430. It should be understood that in some embodiments, the housing mount 1431 may be integrated with the detection housing 1430, for example, as a single integral component.

[0137] Figure 14 The position detection device 1400 can be configured to be mounted on one or more parts of the bicycle. For example, the size and shape of the position detection device 1400 can be configured to complement one or more parts. As described above, the position detection device 1400 may include... Figure 14housing mount 1431. The illustrated housing mount 1431 includes a mounting element 1472. The mounting element 1472 is shown as a complementary profile to a bicycle component. However, it should be understood that the mounting element 1472 can be provided as a fastener, adhesive, or other element for securing the position detection device 1400 to a bicycle component. As Figure 15 shown, the mounting element 1472 includes a mounting surface 1474. The mounting surface 1474 is sized and shaped to mount to a bicycle component. In Figure 14 and Figure 15 examples, the mounting surface 1474 is configured to mount on a generally tubular component or portion. For example, the mounting surface 1474 can be sized and shaped to conform to a profile of a bicycle fork (e.g., the fork 700 of Figure 7 or the fork 108 of Figure 1 ).

[0138] Turning to Figure 15 , a perspective view of the position detection device 1400 is provided. As Figure 14 and Figure 14 shown, at least one alignment element can be provided. For example, a first alignment element 1476 can be provided to define or assist in alignment of the position detection device 1400. In embodiments, the first alignment element 1476 cooperates with a complementary alignment element (not shown) on a bicycle component to assist in alignment during mounting. The first alignment element 1476 can be used for visual assistance in alignment, and / or can physically interfere with misaligned positions. Turning to Figure 15 , a second alignment element 1477 can be provided. The second alignment element 1477 can cooperate with a complementary alignment element (not shown) on a bicycle component. Additionally or alternatively, the first and second alignment elements 1476, 1477 can cooperate with each other, and / or with an alignment tool (not shown), to assist in alignment visually and / or physically. Figure 15 Referring to

[0139] , the position detection device 1400 includes a cover element 1435. The cover element 1435 can be provided for user access, for example to access the interior of the battery housing 1433. In embodiments (e.g., where the detection housing 1430 is a unitary structure with the housing mount 1431), the cover element 1435 can be the only access to the interior of the detection housing 1430. It should also be understood that the position detection device 1400 can also be provided as a sealed unit, with no access for maintenance. However, as Figure 14 shown, the cover element 1435 is removably coupled to the detection housing 1430, for example by one or more fasteners 1437. Figure 14

[0140] Turning now to Figure 16 , a perspective view of the position detection device 1400 is provided. As​ Figure 14 A cross-sectional view of the position detection device 1400 taken along the section line 16-16. The position detection device 1400 can include one or more detection elements, such as the detection elements described above with reference to Figures 2 to 4 FIG. 1. In the example shown, a first detection element 1420, a second detection element 1422, and a third detection element 1424 are provided. As described above (e.g., with reference to Figure 14 FIG. 1), the first detection element 1420, the second detection element 1422, and the third detection element 1424 can generally be configured to provide position data for a remotely detectable element (not shown), such as an element housed in a distinct bicycle component. Figures 2 to 4

[0141] Still referring to FIG. 14, the first detection element 1420, the second detection element 1422, and the third detection element 1424 are each in communication with a processor 1428. The processor 1428 is configured to process data from the first detection element 1420, the second detection element 1422, and the third detection element 1424, such as for determining the position of a bicycle component described elsewhere herein. A communication interface 1432 is provided in communication with the processor 1428. In the example shown, the processor 1428 includes a radio in communication with the communication interface 1432, which is provided as an antenna. Figure 16

[0142] The first detection element 1420, the second detection element 1422, and the third detection element 1424 can be positioned apart from, or otherwise isolated from, various other components. For example, the first detection element 1420, the second detection element 1422, and / or the third detection element 1424 can be isolated from components that can generate electromagnetic interference. As Figure 16 ​​As shown, the communication interface 1432 is located on the side of the printed circuit board (PCB) 1482 opposite to the first detection element 1420, the second detection element 1422, and the third detection element 1424. The power supply 1426 is also located on the side of the PCB 1482 opposite to the first detection element 1420, the second detection element 1422, and the third detection element 1424. The power supply 1426 can be a battery, such as the button cell battery or coin cell battery shown. The PCB 1482 inherently provides electromagnetic isolation to prevent the power supply 1426 and / or the communication interface 1432 from interfering with the first detection element 1420, the second detection element 1422, and the third detection element 1424. In one example, the PCB 1482 is configured to isolate the first detection element 1420, the second detection element 1422, and / or the third detection element 1424 from electromagnetic interference, for example, through metal shielding. It should also be understood that additional shielding elements may be provided. In this embodiment, the first detection element 1420, the second detection element 1422, and the third detection element 1424 can be located away from electromagnetic interference elements.

[0143] Still refer to Figure 16 A light-emitting element 1478 may be provided. The light-emitting element 1478 can be used as a visual indicator for the user, for example, to confirm status. In various examples, the light-emitting element 1478 can be operated to confirm working status, mating status, and / or error status. In this example, a lens 1480 may be provided together with the light-emitting element 1478. The lens 1480 can be any light-transmitting element provided together with the detection housing 1430. For example, the detection housing 1430 or a portion thereof may be transparent or translucent. The lens 1480 may also be provided together with the light-emitting element 1478 and / or the detection housing 1430 (or a portion thereof, e.g., Figure 14 The cover element 1435 shown is integrated. The lens 1480 can be configured to seal with the detection housing 1430 to provide light transmission while maintaining weather resistance, thereby protecting the components inside the detection housing 1430.

[0144] Turn now Figure 17 This provides another example of a position detection device 1700. The position detection device 1700 described herein is configured to connect to a braking system. The detectable element 1716 can be fixed relative to various braking elements. For example, such as... Figure 17 As shown, the detectable element 1716 is attached to a braking element (e.g., master cylinder piston 1768). The master cylinder piston 1768 is translatable along the cylinder axis M through the master cylinder 1762. Therefore, the detectable element 1716 (also referred to as a field generating element) can move together with the master cylinder piston 1768. Detection can be performed relative to the detection plane P by a first detection element 1720 or other detection elements (not shown). For example, it can be referred to above... Figures 2 to 4As illustrated in the example, the detection is performed parallel to and / or perpendicular to the detection plane P. The cylinder axis M can be aligned relative to the detection plane P. For example, as... Figure 17 As shown, the cylinder axis M can be parallel to the detection plane P.

[0145] Figure 17 The example includes a brake body 1758 and a brake lever 1760 pivotally attached to the brake body 1758, the brake lever 1760 being operable to control a master cylinder piston 1768. The master cylinder piston 1768 includes a first cylinder seal 1764 and a second cylinder seal 1766, each sealing between the master cylinder piston 1768 and the master cylinder 1762. Figure 17 As shown in the example, the detectable element is positioned along the cylinder axis M between the first cylinder seal 1764 and the second cylinder seal 1766. The main cylinder 1762 can maintain normal fluid communication or selective fluid communication with the reservoir 1770. Figure 17 In the example, master cylinder 1762 maintains selective fluid communication with the reservoir, controlled by a first cylinder seal 1764 and a second cylinder seal 1766. It should be understood that the detectable element 1716 may be adapted to contact with brake fluid. For example, the detectable element 1716 may be made of a material selected to have a non-corrosive interaction with the brake fluid. It should also be understood that the detectable element 1716 may be sealed to avoid contact with the brake fluid.

[0146] As described above, the detectable element 1716 can be detected by at least the first detection element 1720. The first detection element 1720 may be configured to be connected to, for example, integrated into or housed within, the brake body 1758. Figure 17 In this example, the first detection element 1720 is housed within a detection housing 1730 outside the master cylinder 1762. The detection housing 1730 may be at least partially integrated with the brake body 1758. In this example, the detection housing 1730 may be directly mounted onto the brake body 1758. The first detection element 1720 communicates with a processor 1728, a power supply 1726, and a communication interface 1732, the respective configurations of which can be referred to in related examples described elsewhere herein.

[0147] The position detection device 1700 can be mounted on the handlebars (not shown) around the handlebar axis H, for example... Figure 1 The handlebars are 114. The handlebar axis H can be parallel to the detection plane P. Alternatively, the handlebar axis H can be at a certain angle relative to the detection plane P, such as... Figure 17from the handlebar axis H generates a force that actuates the brake lever 1760, which is operable to move hydraulic fluid through the master cylinder piston 1768 to generate a braking force. Movement of the master cylinder piston 1768 in the compression direction C or in a direction opposite the compression direction C can be detected by the first detection element 1720 detecting the detectable element 1716. Subsequently, a signal indicative of the position of the detectable element 1716 can be transmitted through the communication interface 1732 to provide data regarding the braking operation.

[0148] Turning now to Figure 18 , a rear view of a front fork 1900 is provided. The front fork 1900 can generally be used with any of the individual position detection devices described herein or any combination thereof. As shown in Figure 18 , the front fork 1900 includes a riser tube 1902 connected to a crown assembly 1904. The crown assembly 1904 is in turn connected to an upper assembly 1906, which is in turn connected to a lower assembly 1908. The lower assembly 1908 includes a wheel mounting portion 1910 and a brake mounting portion 1916 for controlling a front wheel (not shown).

[0149] Figure 18 The lower assembly 1908 and the upper assembly 1906 together define a damper portion 1912 and a spring portion 1914 in Figure 18 . For example, as shown in , the spring portion 1914 can be disposed on one leg of the front fork 1900 and the damper portion 1912 can be disposed on the other leg of the front fork 1900. However, it should be understood that the spring portion 1914 and the damper portion 1912 can be combined in a single leg.

[0150] Figure 18 Figure 18 Examples of the front fork 1900 also provide a position detection housing 1918. The position detection housing 1918 can be sized and shaped to contain any number of position detection elements and related components that will be described in greater detail below. The position detection housing 1918 can be at least partially made of a radio frequency transparent material. For example, the position detection housing 1918 can contain a polymeric element, such as a nylon element, to facilitate wireless transmission between the interior and exterior of the position detection housing 1918. As shown in Examples of the front fork 1900, a user interface 1927 can also be provided on the position detection housing 1918, such as for facilitating a user to turn power on, turn power off, initiate pairing, or otherwise command operation of the position detection devices housed therein. The user interface 1927 can be configured to maintain a sealed environment of the position detection housing 1918. For example, the position detection housing 1918 can be sealed relative to the lower assembly 1908 and the user interface 1927 can be a sealed button that communicates with the interior of the position detection housing by mechanical or electrical means.

[0151] Turning now to Figure 19A side view of the fork 1900 is provided. As shown Figure 19 The power source 1926 can be disposed externally of the position detection housing 1918. For example, the power source 1926 can be a removable battery that is detachably attached to the position detection housing 1918. The power source 1926 and / or the position detection housing 1918 can include one or more sealing features to generally maintain a sealed environment of the position detection housing 1918 and / or the fork 1900.

[0152] As shown in the example of Figure 19 The position detection housing 1918 can be disposed rearward of the fork 1900 relative to the riding direction A. This mounting position can help protect the position detection housing 1918 from obstacles and / or debris. Additionally or alternatively, this position can facilitate communication with other electronic components on the bicycle and / or provide aerodynamic advantages. As shown in the example of Figure 19 The power source 1926 can extend rearward from the position detection housing 1918 in a direction opposite the riding direction A. This positioning of the power source 1926 can achieve similar advantages as the positioning of the position detection housing 1918. Further, in this position, the power source 1926 can be easily removed and replaced.

[0153] Turning now to Figure 20 A cross-sectional view of the fork 1900 taken along the cut line 20-20 in Figure 18 is provided. Figure 20 This cross-sectional view further provides details of the damper portion 1912. As shown in the example of Figure 20 The damper portion 1912 includes a damper shaft 1961 that at least partially controls a compression assembly 1960 and extends between the upper assembly 1906 and the lower assembly 1908. The compression assembly 1960 generally controls the restriction of fluid when the fork 1900 is compressed in the compression direction C, and can be adjusted according to user needs and preferences. It should also be understood that the compression assembly 1960 can be configured to additionally or alternatively control the rebound force in a direction opposite the compression direction C.

[0154] Still referring to Figure 20 The damper shaft 1961 is fixed relative to the upper assembly 1906 and is movable relative to the lower assembly 1908. However, it should be understood that the opposite configuration can also be provided, for example, repositioning the position detection housing 1918 and related components onto the upper assembly 1906. But in the present example of Figure 20 The floating piston 1958 is housed in the lower assembly 1908, the position detection housing 1918 is arranged to detect movement of the floating piston 1958, which will be described in greater detail below.

[0155] Figure 21 is a magnified cross-sectional view of the fork 1900 (as Figure 20 (As indicated by label 21 in the text). Figure 21 As shown in more detail, the floating piston 1958 is movably housed within the damper body 1957. In some examples, the portion of the damper body 1957 that houses the floating piston 1958 may be referred to as the IFP housing, where "IFP" is an abbreviation for "internal floating piston," another name for the floating piston 1958. The floating piston 1958 can move in response to the compression and rebound of the fork 1900, for example by... Figure 20 The movement of the damper shaft 1961 shown is realized. (As...) Figure 21 As shown, fluid from the first oil chamber 1962 is movable (e.g., flowing through the rebound assembly 1959) into the second oil chamber 1963. The rebound assembly 1959 may be a laminated assembly structure as shown, or may be provided in other forms. When fluid (e.g., suspension oil) is displaced into the second oil chamber 1963, the floating piston 1958 must also move. The floating piston 1958 is freely movable downward (e.g., along the damper axis Q) by the fluid in the compressed air chamber 1964. The air chamber 1964 is pressurized to ensure that the floating piston 1958 controls the fluid behavior in the damper section 1912 (e.g., to prevent cavitation), while still allowing the floating piston 1958 to move proportionally to the compression and rebound of the fork 1900.

[0156] As described in the example above, the floating piston 1958 can be configured to move proportionally to the movement of the fork 1900. More specifically, the amount of movement of the floating piston 1958 can be proportional to the relative movement between the upper assembly 1906 and the lower assembly 1908. That is, there is a constant or near-constant ratio between the amount of movement of the upper assembly 1906 relative to the lower assembly 1908, the amount of movement of the floating piston 1958, and the amount of movement of the damper body 1957. In some examples, this ratio can be approximately 10:1 for the suspension movement to the IFP movement. Therefore, the position measurement of the floating piston 1958 can generally be correlated with the position of the fork 1900 along the compression direction C. It should also be understood that detecting the floating piston 1958 can have independent value, for example, for determining whether the fork 1900 is operating outside a threshold range, or for determining whether it is in an operational state (rather than in a transport or movement state).

[0157] Still refer to Figure 21One or more detection elements and detectable elements as described elsewhere herein can be provided. As shown, a detectable element 1965 is provided in the floating piston 1958. The detectable element 1965 is held relative to the floating piston 1958 with a detectable element retainer 1966. As shown, the detectable element retainer 1966 is a resilient collar, but can be any retaining feature, including an adhesive or a magnetic retaining feature. The detectable element 1965 can be a permanent magnet, or other suitable detectable configuration selected according to the type of detection element implemented.

[0158] Figure 21 In the example shown, the first detection element 1920 is spaced apart from the second detection element 1922. However, it should be appreciated that only the first detection element 1920 can be employed, for example, when the amount of movement of the floating piston 1958 along the damper axis Q is relatively short (compared to the relatively long amount of movement of the fork 1900) and sufficient detection range and resolution can be achieved with only one detection element. In the present example, the first detection element 1920 and the second detection element 1922 are each provided on a PCB 1982. The PCB 1982 can be configured with any number of elements as described elsewhere herein. As shown, the PCB 1982 includes a processor 1928 and a communication interface 1932. The communication interface 1932 can be a wireless radio, for example, for receiving and transmitting wireless signals with an external device.

[0159] As shown in Figure 21 , the power source 1926 can be removably held relative to the fork 1900. For example, the power source 1926 can be removably attached to the position detection housing 1918 with a battery latch 1937. The present example provides a rotatable configuration of the battery latch 1937 that is mounted to the position detection housing 1918 with a latch pin 1933. A first end of the power source 1926 is selectively engaged by rotation of the battery latch 1937, while an opposite end of the power source 1926 is engaged with the position detection housing 1918 with a power source positioning feature (shown as a battery tab in the figures). It should be appreciated that in the present example and other examples, the power source 1926 can be used interchangeably with one or more power sources on other components of the bicycle (e.g., a derailleur, a suspension controller, a seat post, a power meter, or any other bicycle electronic component).

[0160] Turning now to Figure 22 , another cross-sectional view of the fork 1900 taken along the cross-sectional line 22-22 in Figure 19 is provided. Figure 22The view more clearly illustrates the spring portion 1914 of the fork 1900. It should be appreciated that other examples described herein can be combined with the example of the present fork 1900. For example, one or more detection elements and detectable elements can be added to the fork 1900. In such examples, data representative of the fork travel (i.e., the travel of the upper assembly 1906 relative to the lower assembly 1908) and data representative of the IFP travel (i.e., the travel of the floating piston 1958 relative to the damper body 1957) can be collected. Since these data are expected to remain in a fixed and predictable relationship, any deviation can be used to indicate a fault condition, such as a fluid leak within the damper portion 1912.

[0161] Turning now to Figure 23 , a side view of a shock absorber 2000 is provided, which can employ any of the position detection devices described herein. Figure 24 is a second side view of the shock absorber 2000 and will be described in conjunction with Figure 23 . The shock absorber 2000 generally includes a first mounting portion 2010 and a second mounting portion 2011. As shown, the first mounting portion 2010 and the second mounting portion 2011 each have a lug configuration, but can be mounted to any type of bicycle frame element in other ways as well. Movement of the first mounting portion 2010 relative to the second mounting portion 2011 along an axis T can provide suspension for a bicycle to which the shock absorber 2000 is attached.

[0162] In the present example, the first mounting portion 2010 is connected with a cap assembly 2004, which is part of an outer assembly 2006. The second mounting portion 2011 is connected with a damper body 2057, which is part of an inner assembly 2008. The inner assembly 2008 can move telescopically within the outer assembly 2006 along the axis T. Each of the inner assembly 2008 and the outer assembly 2006 can be individually referred to as a suspension element. The outer assembly 2006 includes an air canister 2002 in which the damper body 2057 can be housed. A spring portion 2014 is provided within the outer assembly 2006, which is tuned to resist compression of the shock absorber 2000. Although the spring portion 2014 shown and described herein is of an air spring configuration, it should be appreciated that a coil spring can also be employed in the present example. Further, a damper portion 2012 is also provided, and is tuned to control compression and extension of the shock absorber 2000.

[0163] Figure 23 and Figure 24The example shown also depicts a position detection housing 2018. Position detection housing 2018 can typically be configured as any other position detection housing described herein. As shown, position detection housing 2018 is positioned on outer assembly 2006 near damper body 2057. This example location of the position detection housing, as will be described in more detail below, contributes to a compact package and reliable position detection.

[0164] Turn now Figure 25 2000 shock absorbers were provided. Figure 24 A sectional view taken along the central section line 25-25. (See figure.) Figure 25 As shown, a damper shaft 2061 is provided to partially control the flow of fluid between a first oil chamber 2062 and a second oil chamber 2063. When fluid enters the second oil chamber 2063 from the first oil chamber 2062 across the laminate assembly 2059, the compressible fluid in the air chamber 2064 expands, moving the floating piston 2058 such that the total volume between the first oil chamber 2062 and the second oil chamber 2063 remains constant when the damper shaft 2061 retracts from the combined volume. The damper shaft 2061 is sealed by an inner seal 2045 of the sealing head.

[0165] exist Figure 25 In the example, a sealing head assembly 2044 is provided to hold an inner sealing head seal 2045 and an outer sealing head seal 2046. The inner sealing head seal 2045 sealably isolates the second oil chamber 2063 from the spring portion 2014 (shown as an air spring). The outer sealing head seal 2046 sealably isolates the positive spring volume from the negative spring volume in the spring portion 2014. The inner and outer sealing head seals 2045 and 2046 cooperate to allow the spring portion to compress air and function as a suspension spring.

[0166] like Figure 25 As shown, a detectable element 2065 is provided on the sealing head assembly 2046. The detectable element 2065 may be a permanent magnet or any other suitable detectable element described elsewhere herein. The detectable element 2065 is fixed relative to the sealing head by a detectable element limiter 2066, which may be a resilient retaining ring or any other suitable fixing element described herein. The detectable element 2065 may also be integrally formed with the sealing head assembly 2044, for example, co-molded with the sealing head assembly 2044.

[0167] Various position detection housings and their internal components are described elsewhere in this document, and these position detection housings and their internal components can be applied to... Figure 25of the first detection element 2020 and the second detection element 2022 are powered by an internal power source 2026. Also provided on the PCB 2082 inside the position detection housing 2018 are a communication interface 2032 and a processor 2028. In Figure 25 In the example of FIG. 20, the first detection element 2020 can be operable to detect a position of the detectable element 2065 across at least one of the outer assembly 2006 and the inner assembly 2008.

[0168] Turning now to Figure 26 , a side view of a shock absorber 2100 is provided, which can employ any of the position detection apparatuses described herein. Figure 27 is a second side view of the shock absorber 2100 and will be described in conjunction with Figure 26 . The spring and damper component configuration of the example of FIG. 21 can generally be the same as the shock absorber 2000 described previously. As shown in Figure 26 and Figure 27 , the shock absorber 2100 can be mounted using a first mounting portion 2110 and a second mounting portion 2111. The first mounting portion 2110 is connected with an outer assembly 2106, which includes a cover assembly 2104, a gas canister 2102, and a spring portion 2114. The second mounting portion 2111 is connected with an inner assembly, which includes a damper body 2157 and a damper portion 2112.

[0169] Figure 26 The example of FIG. 21 also provides a reservoir body 2183, sometimes also referred to as an external reservoir or a backpack reservoir. The reservoir body 2183 in the example of FIG. 21 is configured to house an IFP as described elsewhere herein, and more particularly, the IFP of the example of FIG. 21 will be described in conjunction with Figure 28 and Figure 29 below. As shown, the reservoir body 2183 is connected with a first position detection housing 2118 adjacent to a power source 2126. As will be described below, one or more additional or alternative position detection housings can be provided, for example, that are connected with the power source 2126 and adjacent to the reservoir body 2183.

[0170] Turning now to Figure 28 , a cross-sectional view of the shock absorber 2100 is provided taken along the cut line 28-28 in Figure 26 . Figure 29 is an enlarged cross-sectional view corresponding to the reference 29 in Figure 28 and will be described in conjunction with Figure 28 . Figure 28 and Figure 29The view shows that the reservoir body 2183 houses a floating piston 2158. The floating piston 2158 moves relative to the increase or decrease of the fluid volume of the first oil chamber 2162 and is pressure-supported by the air pressure in the air chamber 2164. The movement of oil across the lamination assembly 2159 and in and out of the first oil chamber 2162 represents the compression of the shock absorber 2100. Thus, the floating piston 2158 can act as a “proxy” for the shock absorber 2100 to move as a whole in a manner similar to that described above with reference to the fork 1900.

[0171] Still refer to Figure 29 The detectable element is connected to the floating piston 2158, as shown in the figure, and is held by a detectable element limiter 2166. A first detection element 2120 is disposed on a PCB 2182 within a first position detection housing 2118. Additionally, a processor 2128, a user interface 2127, and a communication interface 2132 are provided, as described elsewhere herein. The first detection element 2120 shown in this view has a first detection axis P1 that overlaps with but is not concentric with the reservoir axis R representing the stroke of the floating piston 2158. Therefore, the first detection axis P1 can be parallel to the stroke of the floating piston 2158 along the reservoir axis R.

[0172] Turn now Figure 30 It provides shock absorbers 2100 along Figure 27 Another sectional view taken along the central section line 30-30. (See example...) Figure 30 As shown, a second position detection housing 2119 can be provided. The second position detection housing 2119 can be used as a supplement to or alternative to the first position detection housing 2118. In the example, the first position detection housing 2118 uses its first detection element 2120, and the second position detection housing 2119 uses its second detection element 2122, to collaboratively measure the position of the detectable element 2165. It should be noted in this example that the first detection axis P1 of the first detection element 2120 and the second detection axis P2 of the second detection element 2122 are angularly offset (e.g., orthogonally offset).

[0173] If the first detection element 2120 and the second detection element 2122 are used together, they may share other components such as the power supply 2126, the communication interface 2132, and / or the processor 2128. Alternatively, replicas of these components may also be provided for the second detection element 2122. Figure 30 As shown, the power supply is secured to a position adjacent to the second detection element 2122 by a battery latch 2137, latch pin 2133 and power supply positioning feature 2131, which are similar to those described above with reference to the fork 1900.

[0174] exist Figure 30In partial cross-sectional view, a portion of the seal head assembly 2144 is visible and includes a seal head outer seal 2146. This construction can generally be similar to that described above with reference to the shock absorber 2000. For example, the present example includes a second oil cavity 2163 that is partially sealed by the seal head assembly 2144 to move across the stack assembly 2159 into the first oil cavity 2162 as the shock absorber 2100 is compressed. Still referring to Figure 30 A coil spring 2145 is provided as a negative spring. It should be understood that a coil negative spring can be employed in place of, or in addition to, the air negative spring, just as a coil and air positive spring can be interchanged.

[0175] Turning now to Figure 31 A flowchart describing a method of position detection is provided. It should be understood that the example methods described herein can be applied to any of the position detection devices 200, 800, 1000, 1100, 1200, 1400, 1700 described above. In step 1801, a mobile detectable element 216, 816, 916, 1016, 1116, 1216, 1716 is moved. For example, the detectable element can be moved along a travel path over a range of travel, such as translated along an axis G, M, Q, S, T relative to one or more other elements. This movement can define an infinite number of positions. In examples, the detectable element 216, 816, 916, 1016, 1116, 1216, 1716 can be moved between a first position and a second position.

[0176] Still referring to Figure 31 the method, in step 1802, a first output is generated. The first output can be generated by a first detection element 220, 820, 1020, 1220, 1420, 1720. The first output is indicative of movement of the detectable element from the first position to the second position. In step 1803, a second output is generated. The second output can be generated by a second detection element 222, 822, 1022, 1222, 1422. The second output is different than the first output, such as indicative of a measurement from a different position. The second output is indicative of movement of the detectable element 216, 816, 916, 1016, 1116, 1216, 1716 from the first position to the second position.

[0177] Figure 31The method continues to step 1804, determining position data based on the first output and the second output. This determination can be performed by the processor 228, 828, 1028, 1228, 1428, 1728. The method can also continue to transmit the processor output representative of the position data. For example, the processor 228, 828, 1028, 1228, 1428, 1728 can transmit the output to a portable device, cloud storage, or various components of the bicycle using the communication interface 232, 832, 1032, 1232, 1432, 1732 for analysis or control as described elsewhere herein.
