In the description of this invention, “plural” means at least two, such as two or three, unless explicitly and specifically limited otherwise.

For example, a process, method, system, product, or device comprising a series of steps or units is not limited to the listed steps or units, but optionally includes unlisted steps or units, or optionally includes other steps or units unique to the process, method, product, or device.

[0018] Referring to FIGS. 1 to 4, a first embodiment of the braking device (10) of the present invention comprises a shaft body (100); a housing (200); and a magnetic induction member (310); The housing (200) is sleeved to the shaft body (100) and arranged coaxially with the shaft body (100), and the housing (200) is provided with a plurality of magnets spaced apart along the circumferential direction of the shaft body (100). Here, one of the magnetic induction member (310) and the magnet assembly (320) is connected to the shaft body (100) and the other is connected to the housing (200). When the housing (200) rotates relative to the shaft body (100), the coil (311) cuts the magnetic field formed by the magnet assembly (320) to generate resistance opposite to the rotational direction of the housing (200) or the shaft body (100), and can perform a braking function for the braking device (10). Furthermore, since the braking force is related to the rotation of the housing (200) or the shaft body (100) rather than friction braking, it does not generate an emergency stop effect, has high safety, and reduces wear. It can extend the service life of the braking device (10), while its structure is simple and easy to manufacture.

[0019] In this embodiment, the braking device (10) may further be equipped with a tire (400), and the tire (400) may be sleeved to the housing (200) to serve as a shock absorber.

[0020] Specifically, referring to FIG. 5, the magnet may include a first magnet (321) and a second magnet (322), and in this embodiment, the first magnet (321) and the second magnet (322) are described as examples. The magnet assembly (320) is rotated counterclockwise in FIG. 5 at speed v, and the magnetic induction member (310) is stationary, and the magnetic field strengths generated by the first magnet (321) and the second magnet (322) are B1 and B2, respectively, and the magnetic pole of the first magnet (321) facing the magnetic induction member (310) is the North Pole, and the magnetic pole of the second magnet (322) facing the magnetic induction member (310) is the South Pole, and the parts cutting the magnetic induction line of the coil (311) are the c-side part and the d-side part, and the length of the projection in the direction of cutting the magnetic induction line of the coil (311) (i.e., the circumferential direction of the shaft body (100)) (i.e., the length of the c-side part or the d-side part along the axial direction of the shaft body (100)) is set to L, and the direction of the induced current generated in the c-side part is set to the forward direction shown in FIG. 5, and the direction of the induced current generated in the d-side part is set to the reverse direction shown in FIG. 5, then c The ampere force generated by the side part is Fc = nB1Lv and the ampere force generated by the d side part is Fd = nB2Lv, where n is the number of turns of the coil (311) and since the direction of the ampere forces of both is clockwise, the resultant force of both is F sum = nB1Lv + nB2Lv and the magnetic field strength generated by the first magnet (321) and the second magnet (322) is equal, that is, B1 = B2 = B, so F sum = 2 * nBLv.

[0021] In this embodiment, the resistance is in a forward relationship with the rotational speed of the housing (200) or shaft body (100), and can also be obtained from F sum = 2 * nBLv, that is, the greater the rotational speed of the housing (200), the greater the resistance opposite to the rotational direction of the housing (200) that occurs when the coil (311) cuts the magnetic field formed by the magnet assembly (320). Therefore, stability is improved because a constant braking force can be applied when the rotational speed of the braking device (10) does not change, while safety is improved because a large braking force can be applied when the rotational speed of the braking device (10) increases, thereby preventing the movement speed of the braking device (10) from becoming excessively fast.

[0022] In this embodiment, the number of magnets is even, and since the plurality of magnets are arranged symmetrically with respect to the axis of the shaft body (100), the distribution of the magnetic field formed by the magnet assembly (320) can be made uniform, and furthermore, the resistance generated by the coil (311) cutting the magnetic field formed by the magnet assembly (320) can be stabilized.

[0023] In this embodiment, the magnetic poles of two magnets symmetrical with respect to the axis (100) are set in the same direction, and the magnetic poles of two adjacent magnets are set in opposite directions. Here, if the installation direction of the magnetic poles of the magnets is defined as the direction toward the axis of the shaft body (100) and the direction oriented toward the axis of the shaft body (100), then if the magnetic poles of two magnets are in the same direction, both magnetic poles of two magnets are oriented toward the axis or oriented toward the axis, and if the magnetic poles of two magnets are in opposite directions, one of the two magnets is oriented toward the axis of the shaft body (100) and the other is oriented toward the axis of the shaft body (100). By the above-described setting of the magnets, the distribution of the magnetic field formed by the magnet assembly (320) can be made uniform, and furthermore, the resistance generated by the coil (311) cutting the magnetic field formed by the magnet assembly (320) can be stabilized.

[0024] In this embodiment, the magnetic induction member (310) is provided with a main body (312) and a plurality of mounting parts (313) installed at intervals along the outer circumference of the main body (312), and since the coil (311) is wound on the mounting part (313), the relative position of the coil (311) and the magnetic induction member (310) can be stabilized.

[0025] In this embodiment, the mounting part (313) can be installed in an "I" shape, which facilitates the winding of the coil (311) and, at the same time, limits the position of the coil (311), thereby preventing the coil (311) from falling off the mounting part (313) in a direction away from the shaft body (100) and stabilizing the overall structure of the coil (311) and the magnetic induction member (310).

[0026] In other embodiments, the mounting portion (313) may be installed in a straight line for winding the coil (311), but is not limited thereto.

[0027] In this embodiment, the maximum width of the coil (311) on the mounting portion (313) along the circumferential direction of the shaft body (100) is equal to the width of the magnet along the circumferential direction of the shaft body (100), and the maximum length of the coil (311) on the mounting portion (313) along the axial direction of the shaft body (100) is greater than or equal to the length of the magnet along the axial direction of the shaft body (100). Therefore, the coil (311) can continuously cut the magnetic field formed by the magnet assembly (320) during the process of moving relative to the magnet, and thereby continuously generate resistance to improve the stability of the resistance.

[0028] In other embodiments, the maximum width of the coil (311) on the mounting portion (313) along the circumferential direction of the shaft body (100) may be greater than the width of the magnet along the circumferential direction of the shaft body (100), but is not limited thereto.

[0029] In this embodiment, the difference between the maximum width of the coil (311) on the mounting portion (313) along the circumferential direction of the shaft body (100) and the width of the magnet along the circumferential direction of the shaft body (100) is a, and the width of the magnet along the circumferential direction of the shaft body (100) is b, where the ratio of a to b is 10% or less, for example, 10%, 8%, or 5%. When a is 0, the coil (311) can continuously cut the magnetic field formed by the magnet assembly (320) during the process of moving relative to the magnet, and when a is greater than 0, both sides of the coil (311) exist in the region corresponding to the same magnetic pole simultaneously for a certain period of time, the current generated in the coil (311) is 0, and the resistance is interrupted.

[0030] In this embodiment, the number of magnets is greater than the number of mounting parts (313), and the difference between the number of magnets and the number of mounting parts (313) is a positive integer. Since the role of the coil (311) of the magnetic field generated by the magnets is continuous and not interrupted, resistance can be continuously generated to improve the stability of the resistance.

[0031] In this embodiment, all coils (311) on a plurality of mounting parts (313) form a closed loop together. Specifically, all coils (311) may be short-circuited and not connected to other devices. In other embodiments, devices such as switches and resistors may be connected externally, but the closed loop of this embodiment does not include devices such as drivers, that is, the current generated by the coils (311) of this embodiment is used only to generate ampere power, or is mainly used to generate ampere power.

[0032] In other embodiments, the coil (311) on each of the plurality of mounting parts (313) may form a closed loop, or the coil (311) on at least two of the plurality of mounting parts (313) may form a closed loop together, but is not limited thereto.

[0033] In this embodiment, a receiving space is formed in the housing (200), and an opening (not shown) is formed on one side of the housing (200) in the receiving space, and a magnetic induction member (310) and a magnet assembly (320) are installed within the receiving space. The braking device (10) further comprises a cover plate (510), and the cover plate (510) covers the opening and serves to protect parts such as the magnetic induction member (310) and the magnet assembly (320), while also forming the exterior of the braking device (10) more regularly.

[0034] In this embodiment, the cover plate (510) and the shaft body (100) and the cover plate (510) and the housing (200) may be fixedly connected by screws, respectively. In other embodiments, the cover plate (510) and the housing (200) may be connected by snapping, welding, or attachment, etc., but are not limited thereto.

[0035] In the present embodiment, the braking device (10) may further be provided with a first bearing (520) and a second bearing (530), the first bearing (520) is installed between the shaft body (100) and the housing (200), and the second bearing (530) is installed between the shaft body (100) and the cover plate (510). By installing the first bearing (520) and the second bearing (530), wear between the shaft body (100) and the housing (200) and between the shaft body (100) and the cover plate (510) can be reduced, and the shaft body (100) can also be supported, and the service life of the shaft body (100), housing (200), and cover plate (510) can be extended.

[0036] Referring to FIGS. 1, 6 and 7, a second embodiment of the braking device (10) of the present invention comprises a shaft body (100); a housing (200); a magnetic induction mechanism (300); and a control mechanism (610). The magnetic induction mechanism (300) is installed within the housing (200) and is used to generate resistance opposite to the rotational direction of the housing with respect to the housing (200) or to generate resistance opposite to the rotational direction of the shaft body (100) with respect to the shaft body (100) through a magnetic field response when the housing (200) is rotated. The control mechanism (610) is connected to the magnetic induction mechanism (300) and used to control the magnitude of the resistance, wherein the magnetic induction mechanism (300) is equipped with a magnetic induction member (310) and a magnet assembly (320), and the structure of the shaft body (100), housing (200), magnetic induction member (310), and magnet assembly (320) can be described by referring to the first embodiment of the braking device (10), so it is not described further here. By installing the control mechanism (610), the resistance can be automatically controlled to expand the application range of the braking device (10) and simultaneously make it intelligent.

[0037] Referring to FIGS. 8 to 12 together, in this embodiment, the control mechanism (610) is equipped with a control member (611) and at least one resistor (612), and the control member (611) is electrically connected to the magnetic induction mechanism (300) and has a first connection part (6111) formed therein. At least two second connection parts (6121) are installed at each end of the at least one resistor (612), and the control member (611) is movable relative to the resistor (612). Accordingly, the first connection part (6111) can be electrically connected to one of the at least two second connection parts (6121) to connect the magnetic induction mechanism (300) to a load having other resistance, thereby enabling the control of resistance.

[0038] In the present embodiment, the braking device (10) may further comprise a first support tube (613), at least one resistor (612) is installed in the first support tube (613), and the regulating member (611) is installed in a ring shape and can rotate relative to the first support tube (613), and the first connecting part (6111) is formed in a groove on the outer circumference of the regulating member (611), and the outer surface of the regulating member (611) is insulated except for the groove, and the groove is conductive. The second connecting part (6121) includes a contact member (6122) and a first elastic member (6123), and the contact member (6122) is electrically connected to the resistor (612). The first elastic member (6123) is used to impart elastic force to the contact member (6122) so that the contact member (6122) contacts the outer circumference of the adjustment member (611), and when the first connection part (6111) rotates to face the second connection part (6121), the contact member (6122) can contact the first connection part (6111), and the contact member (6122) can be electrically connected to the first connection part (6111).

[0039] In this embodiment, an annular groove (6112) is formed on the outer circumference of the adjusting member (611), and the first connecting part (6111) is formed concavely with respect to the annular groove (6112). The end of the contact member (6122) is installed to protrude in an arc shape, so that at least a portion of the contact member (6122) is embedded in the annular groove (6112), and the limit of the contact member (6122) on the axial direction of the first supporting tube (613) can be realized, and the contact member (6122) is prevented from detaching from the adjusting member (611), thereby improving the reliability of the braking device (10).

[0040] In this embodiment, the braking device (10) may be provided with a second support tube (614) and a knob (615) connected to the second support tube (614). The second support tube (614) may be installed in a manner that is sleeved to the first support tube (613), and the adjustment member (611) may be installed on the second support tube (614). Accordingly, the adjustment member (611) may rotate together with the knob (615), and the knob (615) may rotate by receiving force. Furthermore, adjustment may be achieved by driving the adjustment member (611) to rotate it. By installing the knob (615), adjustment of the adjustment mechanism (610) is realized, and adjustment operation can be made convenient. The space occupied by the knob (615) is small, and the overall structure of the adjustment mechanism (610) becomes compact.

[0041] Referring together with FIG. 13, in this embodiment, the braking device (10) may further be provided with a casing (616), and a regulating member (611) and a resistor (612) are installed within the casing (616). An opening (6161) is formed at one end of the casing (616) away from the knob (165), and the opening (6161) is installed in a polygonal shape. A limit member (6141) and a second elastic member (6142) are installed at one end of the second support tube (614) away from the knob (615), and the second elastic member (6142) is used to impart elastic force to the limit member (6141) so that the limit member (6141) contacts the casing (616) during the rotation process of the second support tube (614).

[0042] Specifically, in this embodiment, the opening (6161) includes a plurality of receiving holes (6162) spaced apart along the circumferential direction of the first support tube (613), and when the limit member (6141) is rotated to the receiving hole (6162), the compression distance of the second elastic member (6142) becomes zero, thereby causing the limit member (6141) to be separated from the casing (616), or the limit member (6141) contacts the casing (616) but the force acting on the casing (616) becomes zero, and at this time, one of the first connecting parts (6111) contacts the second connecting part (6121). When the limit member (6141) is rotated between the two receiving holes (6162), the limit member (6141) contacts the casing (616), but the force acting on the casing (616) becomes greater than zero, and at this time, the first connecting part (6111) does not contact even one of the second connecting parts (6121), so that the user can detect whether the knob (615) has been rotated to a predetermined gear during the process of the knob (615) being rotated.

[0043] In other embodiments, the adjusting member (611) may be installed in a straight or arc shape and may be a slide body, and the adjusting member (611) may electrically connect the second connecting part (6121) to the first connecting part (6111) by sliding against the resistor (612).

[0044] In this embodiment, the number of resistors (612) is multiple, and the multiple resistors (612) form multiple resistor groups, each resistor group includes at least one resistor (612), and the multiple resistor groups are installed spaced apart along the axial direction of the first support tube (613), and the number of adjustment members (611) is multiple and equal to the number of resistor groups, and the multiple adjustment members (611) are installed spaced apart along the axial direction of the first support tube (613) and correspond one-to-one with each resistor group, so by connecting the magnetic induction mechanism (300) to a load having other resistance, the adjustment of resistance becomes flexible, the range is wide, and the adaptability is better.

[0045] Referring together with FIG. 14, for example, in this embodiment, the number of resistor groups is three and is used to connect to each of the three wires of the magnetic induction mechanism (300), each resistor group includes four resistors (612), the four resistors (612) are located in the same plane perpendicular to the axial direction of the first support tube (613), four resistors (612) among each resistor group are connected in series, one end of three resistor groups is connected to each other, and a second connection part (6121) corresponding to a plurality of gears is provided between each resistor (612) and in each resistor group. For example, three resistors (612) may be connected to the first speed gear, and six resistors (612) may be connected to the second speed gear.

[0046] In other embodiments, the magnetic induction mechanism (300) may directly draw out two wires and connect them to the control mechanism (610), or the magnetic induction mechanism (300) may draw out two or three wires and connect them to the control mechanism (610) through two wires after passing through a rectifier mechanism (not shown), and is not limited thereto.

[0052] Referring to FIG. 18 and FIG. 19 together, in this embodiment, the adjustment mechanism (620) may further include an elastic return assembly, and the elastic return assembly acts on at least two keys (621) respectively, and when one of the at least two keys (621) is pressed, the other key (621) may spring back up, and accordingly, the number of connected resistors (622) corresponds to the gears, so that no interference occurs between each gear and the circuit is difficult to short-circuit, thus providing high reliability and safety.

[0053] In the present embodiment, the key (621) includes a key body (6212) and a button (6213) installed at one end of the key body (6212), and the conduction part (6211) is installed at the other end of the key body (6212). The elastic return assembly may include a carrier plate (623) and a first limit plate (624). The first limit plate (624) has a first limit slot (6241) formed in an inverted "L" shape or similar to an inverted "L" shape. The first limit plate (624) includes a limit part (6242) corresponding to the first limit slot (6241). A first elastic member (6244) is provided between the carrier plate (623) and the first limit plate (624). The key body (6212) is further provided with a first limit block (6214). A second elastic member (6215) is sleeved on the main body (6212). Specifically, when the key (621) is not pressed, the limit block (6214) is positioned above the limit portion (6242), and during the process of pressing the key (621), the second elastic member (6215) is compressed and deformed, and the limit block (6214) acts on the limit portion (6242) to cause deformation in the first elastic member (6244), and the first limit plate (624) slides relative to the carrier plate (623) (e.g., sliding to the left in FIG. 23) so that the limit block (6214) can enter the first limit slot (6241), and after the first limit plate (624) reaches the bottom surface of the first limit slot (6241), the first limit plate (624) is relative to the carrier plate (623) under the action of the first elastic member (6244). By sliding (e.g., sliding to the right in Fig. 23), the limit block (6214) is restricted to the lower side of the limit portion (6242).When the other key (621) is pressed, the first limit plate (624) slides again against the carrier plate (623) (e.g., sliding to the left in FIG. 23), so that the limit block (6214) of the limit-locked key (621) is separated from the corresponding limit part (6242), and the key (621) can spring back under the action of the second elastic member (6215).

[0054] In this embodiment, the first limit plate (624) is provided with an inclined surface (6243) corresponding to the first limit slot (6241), and the inclined surface (6243) can be used to guide the limit block (6214), making it easier for the limit block (6214) to slide down along the inclined surface (6243) and get caught in the first limit slot (6241), and making the process of pressing the key (621) smooth.

[0055] In this embodiment, a receiving groove (6245) is further formed in the first limit plate (624), and a contact column (6231) is installed in the carrier plate (623). Both the first elastic member (6244) and the contact column (6231) are received within the receiving groove (6245), and since the contact column (6231) is used to contact the first elastic member (6244), the structure and position of the first elastic member (6244) are stable during the compression process.

[0056] Referring to FIG. 20, in a specific other embodiment, the first elastic member (6246) is also installed at one end of the first limit plate (624) and can simultaneously come into contact with the inner wall of the carrier plate (623), thereby imparting elastic force to the first limit plate (624), making the structure simple and facilitating manufacturing.

[0057] In this embodiment, a second limit slot (6232) may be further formed in the carrier plate (623), and a limit block (6214) may be accommodated within the second limit slot (6232) and used to implement a limit for the corresponding key (621) in a plane perpendicular to the pressing direction of the key (621) (a horizontal plane shown in FIG. 20). For example, the second limit slot (6232) may implement a limit for the key (621) in the extension direction of the carrier plate (623) (a left-right direction shown in FIG. 20).

[0058] In this embodiment, the key body (6212) is installed in a cylindrical shape, and the second limit slot (6232) can further restrict the rotation of the key body (6212), thereby preventing the limit block (6214) from being misaligned with the corresponding first limit slot (6241) due to the rotation of the key body (6212), and furthermore, the limit block (6214) is not pressed into the first limit slot (6241), thereby improving the reliability of the elastic return assembly.

[0059] In other embodiments, a corresponding limit slot and a limit projection (not shown) may be installed in the key housing (626) that holds the key body (6212) and in the key body (6212), respectively, thereby realizing a limit for the key (621) in a plane perpendicular to the pressing direction.

[0060] In other embodiments, to prevent rotation of the key body (6212), the key body (6212) may be directly installed as a rectangular column or a column of another shape, but is not limited thereto.

[0061] Referring to FIG. 20, in a specific other embodiment, the elastic return assembly may further include a plurality of second limit plates (625), and the plurality of second limit plates (625) are arranged sequentially along the extension direction of the first limit plate (624), and a third limit slot (6251) may be formed between two adjacent second limit plates (625), thereby implementing a limit for the key (621) in a plane perpendicular to the pressing direction. Specifically, after the key (621) is pressed, the limit block (6214) acts on two adjacent second limit plates (625), thereby extruding the two adjacent second limit plates (625) to both sides of the limit block (6214), and the other second limit plates (625) come into close contact with each other, thereby forming a third limit slot (6251) to accommodate the limit block (6214) and realizing a limit for the limit block (6214).

[0062] In this embodiment, an inclined surface (6252) may be further formed on the second limit plate (625), and the inclined surface (6252) may be used to guide the limit block (6214), facilitating the limit block (6214) to slide down along the inclined surface (6252) and get caught in the third limit slot (6251), and making the process of pressing the key (621) smooth.
