Description

Technical Field

[0001] The present disclosure relates to skateboards and, more particularly, to skateboard frames for improving stability and maneuverability. Background Art

[0002] Skateboarding originated in California in the 1940s as an offshoot of surfing ("asphalt surfers"). Since then, the shape and handling of the skateboard have changed only slightly. The kicktail was added in the 1960s. Urethane wheels were added in the 1970s. The 1970s also saw subtle changes in the shape of the skateboard, such as increased width and concavity. More recently, skateboards have been equipped with electric motors and wireless hand-held throttle remote transmitters. Skateboards are no longer just toys, but are often used by people to travel longer distances at higher sustained speeds.

[0003] There are three key components to a skateboard, the deck or board, the wheels, and the truck. The “truck” refers to the part that connects the wheels to the deck. One of the early truck designs was the Traditional Kingpin, which combined a base plate with a kingpin and a pivot cup (the part of the base that fits the suspension fulcrum on the pivot cup, which facilitates turning and shock absorption) and a hanger suspended between the kingpin and the pivot cup, so that the wheel axis is located between the kingpin and the pivot cup. Another design is the reverse kingpin, which uses similar components, but the kingpin is located between the wheel axis and the pivot cup. In addition, the double kingpin uses a traditional kingpin configuration, extending from the stacked orientation of the second set of kingpins and pivot cups.

[0004] It is generally understood in the art that a bushing or a pair of bushings is used to secure the axle and the spike, and that the bushing secures the spiked portion of the axle within the pivot cup. The bushing can flex and compress to allow the axle to move relative to the base. Thus, applying pressure to different parts of the deck will cause the bushing to flex or compress and further movement of the axle. The movement of the axle causes the wheel axis to twist slightly relative to the deck, allowing the skateboard to turn.

[0005] Three link trucks have a different design than the ones previously described, but they still rely on bushings to connect the base plate to the wheel axis.

[0006] While the above designs have been in common use for many years, they also present challenges to skateboard users during operation. Existing designs can be very unstable when traveling at high speeds, both when the skateboard is traveling in a straight line and when turning, because the bushings and other components tend to wear quickly. Existing designs are also prone to sudden and violent speedwobbles, which can cause the skateboard to lose control during use, resulting in a collision and / or serious personal injury to the user. This is especially true when skateboards with electric motors reach higher speeds. Existing designs may also have poor design, poor component quality, insufficient testing, and other performance-related issues. Skateboards with electric motors are able to reach higher speeds, but they also have battery issues, speed control issues, and complex motor drive systems that can lead to excessive failures and premature failures.

[0007] Therefore, there is a need for improved bracket design to increase safety and reliability during skateboard operation. Summary of the invention

[0008] A skateboard comprises a deck, one or more wheels and a bracket connected to the deck and to the one or more wheels, the bracket having a base connected to the deck, a wheel axle connected to the one or more wheels, a shaft extending from the base to the wheel axle, the shaft being capable of rotating relative to the base around a first axis, the wheel axle being capable of rotating relative to the shaft around a second axis that is not parallel to the first axis, and one or more linkages extending from the base toward the wheel axle to cause the wheel axle to rotate as the base tilts.

[0009] A skateboard frame connected to a deck and one or more wheels, the frame comprising a base connected to the deck, a wheel axle connected to the one or more wheels, an axle extending from the base to the wheel axle, the axle being capable of rotating relative to the base around a first axis, the wheel axle being capable of rotating relative to the axle around a second axis that is not parallel to the first axis, and one or more connecting rod mechanisms extending from the base toward the wheel axle to cause the wheel axle to rotate as the base tilts.

[0021] The following disclosure may include methods and apparatus for a skateboard stand. The skateboard stand described in the present disclosure improves stability and handling during use, thereby improving performance and safety. The skateboard stand can be used to connect one or more wheels to the board so that the wheels can be turned by changing the pitch of the board and sudden and rapid swaying can be avoided.

[0022] A skateboard may include a deck and one or more wheels (e.g., four wheels), and may also include one or more brackets for connecting the one or more wheels to the deck (e.g., two brackets, each bracket connecting two wheels). The one or more brackets may be connected at different positions along the length of the deck (e.g., at a front position, at a rear position). The first bracket may be connected at a front position (e.g., at the front of the deck). The second bracket may be connected at a rear position (e.g., at the rear of the bracket, or at a position opposite to the first bracket). The positioning of the first and second brackets may optimize the handling performance of the skateboard during use.

[0023] Each of the one or more brackets may include some or all of the features set forth in the disclosure of the present invention. The bracket may include a base configured to be connected to the deck. The base may be connected to the bottom of the deck. The base may extend from below the deck and / or outward (e.g., forward, rearward).

[0024] The shaft can be connected to the base. The shaft can extend outward from the base. The shaft can extend downward, forward and / or backward from the base. The shaft can be configured to rotate relative to the base about an axis of the shaft (e.g., an axis extending longitudinally through the length dimension of the shaft). The axis can be vertical or horizontal. Rotational movement can be provided by fixing the shaft to the base using one or more bearings while allowing the shaft to rotate. One end of the shaft (e.g., the end opposite the base) includes an eye.

[0025] The axle can extend through the eye of the shaft. The approximate center point of the axle can be located at the eye of the shaft so that about half of the axle can extend from the eye in a first direction and about half of the axle can extend from the eye in a direction opposite to the first direction. The axle can be pinned in place (e.g., by a pin extending through the eye of the axle and the shaft, by a heim rod end, or by other connections that enable full rotation and normal function). The axle can be configured to rotate relative to the shaft about a pin axis (e.g., a pin axis extending longitudinally through the length dimension of the pin). The pin axis can be horizontal. The pin axis can deviate from horizontal. The shaft axis can be orthogonal to the pin axis.

[0026] One or more linkages may extend from the base to the axle. The linkage may include a component (e.g., a fisheye rod end) that enables spherical rotation at each end of the linkage to enable rotational fixation with the base and the axle. Each linkage may be directly fixed to the base. Each linkage may be indirectly fixed to the axle (e.g., fixed to a sleeve around the axle that fixes its connection point along the length of the axle but still allows the axle to rotate within the sleeve). One or more linkages may include two linkages for each axle. The linkages may extend outward from the base, or away from each other to the axle (e.g., the connection point on the base may be relatively close, while the connection point on the axle may be relatively far away). The linkages may extend inward from the base, or toward each other toward the axle (e.g., the connection point on the base may be relatively far away, while the connection point on the axle may be relatively close). The linkages and the axle may form a shape that approximates a triangle together.

[0027] The connecting rod is adjustable and affects the rotation of the wheel axle relative to the base plate and can cause the skateboard to rotate. Changing the angle between the connecting rods relative to each other will affect the turning radius, turning sensitivity and high-speed stability of the skateboard. Increasing the relative angle of the connecting rods will increase the turning radius, increase sensitivity and reduce stability. Reducing the relative angle of the connecting rods will reduce the turning radius, reduce sensitivity and improve stability. When the skateboard has two brackets (e.g., a front bracket and a rear bracket) and each bracket has a pair of connecting rods to achieve steering, the relative angle of a pair of connecting rods in the front bracket may be different from the relative angle of a pair of connecting rods in the rear bracket. The relative angle of the connecting rods in the front pair of connecting rods may be greater than the relative angle of the connecting rods in the rear pair of connecting rods. The relative angle of the connecting rods in the front pair of connecting rods can be about 1 to 5 times the relative angle of the connecting rods in the rear pair of connecting rods. In the present embodiment, the relative angle of the connecting rods in the front pair of connecting rods is about 3 times the relative angle of the connecting rods in the rear pair of connecting rods.

[0028] Figure 1 A front view of a skateboard 100 is shown, which has a deck 110, one or more wheels 120, and at least one bracket 130. The deck 110, one or more wheels 120, and the bracket 130 can be made of one or more of metal, wood, plastic, or a composite material. In the figure, the bracket 130 extends below the deck 110, but other orientations are possible. Typically, the bracket 130 can secure the wheels 120 to the deck 110. The bracket 130 can also provide steering for the skateboard 100.

[0029] Bracket 130 may include base 131. Base 131 may be secured to the bottom side of deck 110, although other orientations are possible. In certain embodiments, base 131 may also be secured to top plate 132. Top plate 132 may be located on the top side of deck 110. Top plate 132 and base 131 may be secured to each other via deck 110 (e.g., via bolts extending through deck 110). Base 131 may be configured to receive shaft 133.

[0030] The shaft 133 may be fixed to the base 131 for rotational movement (e.g., around a vertical axis). The shaft 133 may extend from below the base 131 to the axle 140. The shaft 133 may have two opposing ends. The first end of the shaft 133 may be configured to interconnect with the base 131, and the second end of the shaft 133 may be configured to interconnect with the axle 140. One end of the shaft 133 may be formed as a hollow ring (e.g., an eye) for receiving the axle 140 therethrough.

[0031] The axle 140 can extend through the hollow ring of the shaft 133 (e.g., to a central point along the length of the shaft 140). The pin 135 can extend through the hollow ring portion of the shaft 133 and can further extend through the axle 140. The axle 140 can be configured for rotational movement relative to the shaft 133 about a horizontal axis (e.g., a horizontal axle extends along the length of the pin and passes through the pin).

[0032] The relative movement of the axle 140 and the shaft 133 can be dampened by one or more bushings 137. The bushings 137 can be located around the axle 140 on either side of the shaft 133, or can be located on both sides of the shaft 133. Each bushing 137 can be secured in place by securing rings 139 (e.g., threaded nuts, threaded lock-nuts) extending around the axle 140. The bushings 137 can be compressed against the shaft 133 by the securing rings 139 on each side of the assembly (e.g., one on the right and one on the left). The securing of the bushings 137 by the securing rings 139 can bias the shaft 133 to an orthogonal position relative to the axle 140. Applying a force to the shaft 133 and / or the axle 140 can cause the shaft 133 to move to some other angle relative to the axle 140 (e.g., less than or greater than ninety degrees).

[0033] One or more connecting rods 134 may extend from the base to the axle. At each end of the connecting rod 134, a ball joint (e.g., a fish eye rod end) allows the connecting rod 134 to rotate spherically relative to the component to which it is connected (e.g., the base 131 and / or the axle 140). The connecting rod 134 may be fixed in direct contact with the base 131 (e.g., by bolting through the fish eye and fixing it to the base 131). The connecting rod 134 can be fixed without direct contact with the axle 140. The connecting rod 134 can be fixed in direct contact with the sleeve 136 (e.g., by bolting through the fish eye and fixing the connecting rod 134 to the sleeve 136).

[0034] The sleeve 136 may extend around the axle 140. The sleeve 136 may be fixed to the axle 140. The sleeve 136 may not rotate around the axle 140, but may be tightly clamped to the axle 140. Therefore, the link 134 may be fixed at both ends, where one end may be pinned to the base 131 and the other end may be pinned to the axle 140 (e.g., pinned at discrete locations along the length of the axle 140). When two links 134 are connected between the base 131 and the axle 140, each link 134 may have a corresponding sleeve 136 so that each link 134 can move independently of the other link.

[0035] A spacer 138 may be connected to the axle 140. The spacer 138 may surround the axle 140. The spacer 138 may protect the axle 140 from impacts during use of the skateboard 100 (eg, impacts caused by rough terrain).

[0036] Figure 2 A method for connecting a slide plate (e.g., Figure 1 1 and 10. The side view of the bracket 230 of the wheel 220 and the board 210 of the skateboard 100 in FIG. The bracket 230 may include a base 231. The base 231 may be fixed to the board 210. The shaft 233 may be connected to the base 231. The shaft 233 may extend from the base 231 to the wheel axle (e.g., Figure 1 The axle 140 in FIG. 1 ). The axle can extend through the shaft 233 and / or be interconnected with the shaft 233. The sleeve 236 can extend around the axle and / or be fixed to the axle.

[0037] The link 234 (shown in dashed lines) may extend from the base 231 to the sleeve 236. The link 234 may be connected to the base 231 at any one of one or more connection points 291 (e.g., 4 connection points, indicated by numerical indicators 1, 2, 3, and 4). The link 234 may be connected to the sleeve 236 at any one of one or more connection points 292 (e.g., 3 connection points, indicated by letter indicators A, B, and C). Selecting different connection point combinations when securing the link 234 to the base 231 and the sleeve 236 may affect the angle of the link 234 relative to the wheel axle. The angle of the link 234 relative to the wheel axle may affect mechanical properties related to the rotation of the skateboard (e.g., changing the turning radius of the skateboard, adjusting sensitivity, and / or changing stability during rotation).

[0038] Figure 3 A cross-sectional view of a bracket 330 for connecting the wheels and deck of a skateboard assembly is shown. The bracket 330 may include a base 331, a shaft 333, and an axle 340. The shaft 333 may rotate about an axis 351 of the shaft. The shaft 333 may be fixed to the base 331 and configured to rotate using one or more bearings 353. The axle 340 may be fixed to the shaft 333. The axle 340 may extend through a hole 355 in the shaft 333. The axle 340 may be pinned to the shaft 333 (e.g., by a pin 371). The axle 340 may rotate about the pin axis (e.g., as shown in FIG. 35). Figure 4 shown).

[0039] The links 334A, 334B may extend from the base 331 to the axle 340 (the entire span is not fully shown due to the cross-sectional nature of the figure). The shaft 333 and the links 334A, 334B are connected together with the base 331 and the axle 340 combination and work together to produce very precise mechanical movement. The shaft 333 and the base 331 may tilt to the right or left during operation, which represents a rotation about the pin axis. The tilting movement also causes movement of the links 334A, 334B, which can push and / or pull the axle 340. Pushing and / or pulling the axle 340 can cause the axle 340 to rotate relative to the base 331. The rotation of the axle 340 relative to the base 331 can cause the shaft 333 to rotate relative to the base 331 (for example, through the bearing 353).

[0040] In one specific example, when the shaft 333 and the base 331 are tilted to the left (e.g., due to a force applied by a user), the vertical direction of the shaft 333 and the axle 340 may become an acute angle direction (e.g., the 90 degree angle is reduced). When the shaft 333 and the base 331 are tilted to the left, the first link 334A may be pushed, while the second link 334B may be pulled. The first link 334A may be pushed because the tilt to the left may cause the base 331 to try to move toward the connection point between the first link 334A and the axle 340 (e.g., if the first link 334A is removed, the base 331 may move toward the connection point between the first link 334A and the axle 340). However, due to the presence of the first link 334A, the axle 340 may be pushed back by the first link 334A (e.g., away from the page).

[0041] The opposite movement may occur with second link 334B, as the leftward tilt may cause base 331 to attempt to move away from the point at which second link 334B connects to axle 340. Thus, the presence of second link 334B may cause axle 340 to be pulled forward (e.g., into the page). In this case, the push of link 334A and the pull of link 334B may cause axle 340 to rotate about axis 351, and shaft 333 to rotate about axis 351 (e.g., counterclockwise about axis 351 when viewed from above, corresponding to a left turn of the skateboard).

[0042] In another specific example, tilting the base 331 to the right may produce the opposite result as tilting to the left (eg, clockwise rotation about the axis 351 when viewed from above, corresponding to a rightward turn of the skateboard).

[0043] Figure 4 A front view of a skateboard 400 is shown, which has a deck 410, one or more wheels 420, and a bracket 430. Typically, the bracket 430 can secure the wheels 420 to the deck 410. The bracket 430 can also provide steering for the skateboard 400. During operation, a user of the skateboard 400 can apply weight (e.g., force) to the deck 410. When the weight is evenly distributed, the deck can be biased toward a horizontal position (e.g., as shown in FIG. 1 ). Figure 1 137). When the weight distribution is uneven (e.g., shifted laterally to both sides of the skateboard 400), the deck 410 may tilt laterally (e.g., as Figure 2 shown).

[0044] The bracket 430 may include a base 431 fixed to the lower side of the panel 410. The bracket 430 may include a shaft 433 fixed to the base 431. The bracket 430 may include an axle 440 fixed to the shaft 433. The bracket 430 may include a first connecting rod 434A fixed to the base 431 and fixed to the axle 440 on one side of the assembly. The bracket 430 may include a second connecting rod 434B fixed to the base 431 and fixed to the axle 440 on the other side of the assembly. The bracket 430 may include a bushing 437 fixed to the axle 440 on both sides of the shaft 433 and extending around the axle 440.

[0045] The tilt of the deck 410 due to uneven weight distribution may cause the base 431 and / or the shaft 433 to tilt in the same direction (e.g., as shown in FIG. Figure 4 When the base 431 is tilted, the first link 434A and the second link 434B may be pushed and / or pulled (e.g., the first link 434A may be pushed back into the page, and the second link 434B may be pulled forward out of the page). The pushing and / or pulling of the first and second links 434A, 434B may cause the axle 440 to rotate (e.g., the left side wheel 420 moves back into the page, and the right side wheel 420 moves forward out of the page).

[0046] The bushing 437 can provide some resistance to the rotation of the shaft 433 relative to the axle 440 (eg, corresponding to the tilt of the deck 410 ). However, the bushing 437 can conform and / or deflect in response to the rotation of the shaft 433 .

[0047] Figure 5 A method for connecting a slide assembly (e.g., Figure 1 1 and 10. A side view of a support 530 of a wheel 520 and a deck 510 of a skateboard 100 (see FIG. 1 ). The support 530 may have a shock absorber 560 extending from a support element 561 to the wheel axle 540. The support element 561 may be connected to the base 531 (e.g., fixed in a rigid relationship with the deck 510).

[0048] The axle 540 can be coupled to the base 531 or an equivalent structure in a manner that allows the axle 540 to move (e.g., allow rotation). The axle 540 can extend through a ring at one end of the base 531, as described in the present disclosure. The axle 540 can extend through a ring at one end of a shaft (e.g., configured to rotate about a vertically extending pin axis), and the shaft can be configured to rotate relative to the base 531 (e.g., configured to rotate about a horizontally extending axis). The axle 540 can be fixed to the base 531 via a ball joint 543 (e.g., allowing rotational movement about multiple axes and / or rotational movement about a center point of a sphere). The connection between the axle 540 and the base 531 can provide a precise rolling center for the deck 510.

[0049] One or more wheels 520 may be rotatably coupled to axle 540 to allow the skateboard to travel on ground 599. One or more links 534 may extend from base 531 to axle 540 to assist axle 540 in maintaining stability and steering when deck 510 tilts and / or rolls.

[0050] Shock absorber 560 can bias axle 540 to a normal position (e.g., axle 540 extends perpendicular to base 531). In the previous embodiment, axle 540 can be normalized by using one or more bushings located at the connection point of the axle to the shaft, such as Figure 3 and 4 As shown. Figure 5 In the embodiment of the present invention, a bushing is no longer required because the shock absorber 560 can provide a biasing force to normalize the axle 540 relative to the base 531.

[0051] However, the operability of the skateboard assembly is similar. When the board 510 is tilted to the right or left, the axle 540 can rotate relative to the base 531. The rotational motion can be damped, controlled and / or stabilized by the shock absorber 560, the connecting rod 534, or both. This arrangement adds precise compression and rebound adjustability, allowing the user of the skateboard assembly to optimize the tilt and / or board tilt to achieve a very smooth, stable and controlled turn, and be confident that no sudden and rapid shaking will occur.

[0052] Figure 6 A front view of a bracket 630 for connecting wheels 620A, 620B to a deck 610 of a skateboard is shown. The bracket 630 can have shock absorbers 660A, 660B extending from a support element 661 to an axle 640. The support element 661 can be fixed in a rigid relationship with the deck 610 and / or a base 631 extending from the deck 610. The axle 640 can be connected to the support element 661 in a manner that allows the axle 640 to move (e.g., allow rotational movement). The axle 640 can extend through a ring at one end of the base 631. The axle 640 can extend through a ring at one end of a shaft (e.g., configured to rotate about a pin axis), and the shaft can be configured to rotate relative to the base 631 (e.g., configured to rotate about a shaft axis). The axis of the pin and the axis of the shaft can be orthogonal to each other. Axle 640 may be secured to base 631 via a ball joint (eg, allowing rotational movement about multiple axes and / or rotational movement about a center point that provides a precise rolling center).

[0053] One or more wheels 620A, 620B are rotatably connected to the axle 640 to allow the skateboard to travel on the surface. One or more links 634 can extend from the base 631 to the axle 640 to assist the axle 640 in maintaining stability and steering when the board 610 is tipped, tilted and / or swayed.

[0054] The first shock absorber 660A may extend downward and / or laterally from the support element 661 to a position on the axle 640 relatively close to the first wheel 620A. The second shock absorber 660B may extend downward and / or laterally from the support element 661 to a position on the axle 640 relatively close to the second wheel 620B (e.g., the second shock absorber 660B is disposed on opposite sides of the axle 640 relative to the first shock absorber 660A). The shock absorbers 660A, 660B may be fixed to the support element 661 relatively close, and may be fixed to the axle 640 relatively far away. The shock absorbers 660A, 660B and the axle 640 may generally form a triangle.

[0055] Shock absorbers 660A, 660B can bias axle 640 to a normal and / or normal position (e.g., axle 640 extends perpendicular to base 531 and / or extends relative to the length of deck 610). Shock absorbers 660A, 660B can provide the biasing force required to normalize axle 640 relative to base 631 and / or deck 610. When deck 610 tilts or tilts to the right or left, axle 640 can rotate relative to base 631.

[0056] The rotational motion can be dampened, controlled and / or stabilized by the shock absorbers 660A, 660B, the link 534, or all of the shock absorbers, and high-speed rotation can be provided without the use of bushings anywhere in the assembly. This arrangement adds precise compression and rebound adjustability, allowing the user of the skateboard assembly to optimize the tilt and / or board tilt to achieve very smooth, stable and controlled turns. This arrangement can improve stability and maximize the mechanical properties of the shock absorption, minimize and / or eliminate any sudden onset of rapid shaking felt by the skateboard user during use (e.g., racing), thereby maximizing confidence in the performance and maneuverability of the skateboard without having to worry about collisions or personal injury.

Link 734 can have a first eyelet 745 that can be configured to be connected to a first structural element of the skateboard (e.g., connected to Figure 8 The connecting rod 734 can have a second eyelet 746, which can be configured to be connected to a second structural element of the slide (e.g., connected to Figure 8 One or both of the first eyelet 745 and the second eyelet 746 may be capable of spherical rotational movement relative to the structural element to which it is connected (e.g., using a fisheye rod end).

[0058] The piston 747 can extend from one of the first hole 745 and the second hole 746. Figure 7 In FIG. 7 , the piston 747 is illustrated as extending from the first hole 745. The piston cylinder 748 may extend from the other of the first hole 745 and the second hole 746. Figure 7 In the figure, the piston cylinder 748 is illustrated as extending from the second eyelet 746. The piston 747 and the piston cylinder 748 can be coupled to the corresponding eyelets by any means known in the art (e.g., threaded insertion, where the threaded portion of the corresponding eyelet is interconnected with the threaded portion of the piston 747 or the piston cylinder 748). Figure 7 In the embodiment, the piston 747 and the piston cylinder 748 are illustrated as being inserted into the first eyelet 745 and the second eyelet 746, respectively, although other configurations are also contemplated by the present disclosure. The piston 747 can be coupled to the corresponding eyelet at its first end. The piston cylinder 748 can be connected to the corresponding eyelet at the first end of the piston cylinder.

[0059] The first retainer 751 can be connected to the piston 747 (e.g., threadedly connected). The first retainer 751 can be positioned to connect to the eyelet (e.g., the first eyelet 745) connected to the piston 747. In the case where the first retainer 751 and the first eyelet 745 are threadedly connected to the piston 747 (e.g., as Figure 7 ), the first retainer 751 can be threadedly tightened until the surface of the first retainer 751 contacts (e.g., forms a frictional engagement with) the surface of the first eyelet 745. The frictional engagement of the first retainer 751 and the first eyelet 745 (when both are threadedly connected to the piston 747) can fix the piston 747 and prevent relative movement of the piston 747 relative to the first eyelet 745.

[0060] The second retainer 752 can be indirectly coupled to the piston cylinder 748 (e.g., forming a frictional engagement). The second retainer 752 can be positioned to interface with the piston cylinder 748, wherein the second retainer 752 and the piston cylinder 748 are coupled to corresponding holes (e.g., the second hole 746). Figure 7 In the case of the second retainer 752 being threaded and tightened, the second retainer 752 can be threadedly tightened until the surface of the second retainer 752 abuts against the surface of the piston cylinder 748 (e.g., forming a frictional engagement). When the second retainer 752 and the piston cylinder 748 are both threadedly engaged to the second eyelet 746, the frictional engagement of the second retainer 752 and the piston cylinder 748 can fix the piston cylinder 748 and prevent relative movement of the piston cylinder 748 relative to the second eyelet 746.

[0061] The piston cylinder 748 may have an open interior for receiving the piston 747 (e.g., a hole 749 extending into the piston cylinder 748 at the second end of the piston cylinder 748) for receiving the piston 747. The piston 747 may have an opening (e.g., a hole 753 extending through the second end of the piston 747). The piston cylinder 748 may have an opening (e.g., a hole 754 extending through the second end of the piston cylinder 748). The holes 753, 754 may extend orthogonally to the hole 749. The second end of the piston 747 may be inserted into the hole 749 (e.g., until the hole 753 of the piston 747 is aligned with the hole 754 of the piston cylinder 748). The piston pin 755 may be inserted into the hole 754 of the piston cylinder 748 and / or the hole 753 of the piston 747 (e.g., during the alignment of the holes 753, 754) to fix the piston 747 in the piston cylinder 748.

[0062] The piston pin 755 may be sized and dimensioned to fit snugly within the bore 753. The piston pin 755 may be secured within the bore 753 by a dowel pin, screw, pin, friction engagement, or other fastening means (e.g., a third retainer 759). The piston pin 755 may be sized and dimensioned to extend outwardly from the bore 753 and through a bore 754 of the piston cylinder 748 (e.g., at one or both ends of the piston pin 755). The bore 754 may be sized and dimensioned to be slotted and / or substantially larger than the piston pin 755. The clearance between the size of the piston pin 755 and the size of the bore 754 may enable the piston 747 to move relative to the piston cylinder 748 (e.g., the piston 747 may translate and / or linearly move relative to the piston cylinder 748) as the piston pin 755 moves within the bore 754 of the piston cylinder 748.

[0063] The piston 747 and the piston cylinder 748 can be biased to a first position (e.g., Figure 7 756). The bias may be provided by a biasing device (e.g., a spring 756 may be positioned to bias the piston 747 and the piston cylinder 748 to the first position). The spring 756 may be held between the first holder 751 and the piston cylinder 748. The first holder 751 may have a fixing surface 757 shaped and dimensioned to receive and / or align the spring 756. The piston cylinder 748 may have a fixing surface 758 shaped and dimensioned to receive and / or align the spring 756. The spring 756 may be fixed and / or aligned between the fixing surface 757 of the first holder 751 and the fixing surface 758 of the piston cylinder 748. The shape and / or size of the fixing surfaces 757, 758 may include one or more of a lip extending around its periphery, a lip extending around its inner periphery, and a groove extending into its surface for receiving the spring 756.

[0064] The spring 756 can move the fixing surfaces 757, 758 away from each other. The spring 756 can bias the first fixture 751, the piston 747 and / or the first eyelet 745 in a direction opposite to the second fixture 752, the piston cylinder 748 and / or the second eyelet 746. When the connecting rod 734 is mounted on the skateboard, the tilting of the board surface and / or the rotation of the axis can cause the force on the connecting rod 734 to change (e.g., compress). If the force applied to the connecting rod 734 exceeds the biasing force of the spring 756, the spring 756 can be deformed (e.g., compressed) so that the piston 747 can move relative to the piston cylinder 748 (e.g., move to the second position).

[0065] During deformation of the spring 756, the piston 747 may move into or out of the bore 749 of the piston cylinder 748 or out of the bore 749. The piston 747 may move between a first position and a second position, or between any intermediate positions between the first position and the second position. The first position may correspond to a piston pin 755 disposed on one side of the bore 754, while the second position may correspond to a piston pin 755 disposed on the other side of the bore 754. The first position may correspond to a specified distance between the fixing surfaces 757, 758, while the second position may correspond to a different distance (e.g., a larger distance) between the fixing surfaces 757, 758. The first position may correspond to a specified distance between the first and second eyelets 745, 746, while the second position may correspond to a different distance (e.g., a larger distance) between the first and second eyelets 745, 746.

[0066] Figure 8 A perspective view of a bracket 830 for connecting wheels 820 and a deck 810 of a skateboard 800 is shown. The bracket 830 may include a base 831. The base 831 may be fixed to the bottom side of the deck 810, but other orientations are also possible. An axle 840 may be disposed below the base 831. As described in the present disclosure, the axle 840 may be interconnected with the base 831, such as by a rotation axis (e.g., Figure 1 The axle 840 may be configured to rotate relative to the base 831 (eg, about a horizontal axis).

[0067] The axle 840 may also be connected by one or more connecting rods 834 (e.g., similar to Figure 7 The connecting rod 834 can be interconnected with the base 831. The first end of the connecting rod 834 can be fixed to the base 831. The second end of the connecting rod 834 can be fixed to the axle 840 (for example, fixed to the sleeve 836, and the sleeve 836 is fixed to the axle 840). One or more connecting rods 834 can stabilize the movement of the axle 840 relative to the base 831 and / or the skateboard 800.

[0068] When the connecting rod 834 is mounted on a skateboard, tilting of the skateboard deck and / or rotation of the axle may cause a change in the force applied to the connecting rod 834 (e.g., compression). The axle 840 may rotate to the right (e.g., the right wheel moves backward relative to the skateboard deck 810 and the left wheel moves forward) may cause a change in the force applied to the connecting rod 834. The connecting rod 834 may be compressed. The piston (e.g., Figure 7 The piston 747 in the piston may be pushed into the piston cylinder (e.g., Figure 7 The piston cylinder 748 in the piston cylinder 748 makes the spring (for example, Figure 7 The spring 756 in the slide 810 may be compressed. The leftward rotation of the axle 840 (e.g., the right wheel moves forward relative to the skateboard deck 810 and the left wheel moves backward) may cause a change in the force applied to the connecting rod 834. The connecting rod 834 may be stretched. The piston (e.g., Figure 7 The piston 747 in the piston cylinder (eg, Figure 7 The piston cylinder 748 in the cylinder is pulled open, so that the spring (e.g., Figure 7 The spring 756 in the slide 800 may expand. In this way, the link 834 (e.g., spring 756) may bias the axle 840 in a direction orthogonal to the length of the deck 810. The user of the skateboard 800 tilting the deck 810 may cause the axle 840 to rotate as described in the present disclosure (e.g., rotating about a vertical axis). The tilting of the deck 810 may further generate a force that opposes the bias caused by one or more links 834 and may further stabilize the axle 840 and improve maneuverability during use.

[0069] Fig. 9 A rear isometric view of an electric skateboard assembly 900 is shown. The skateboard 900 may have features similar to those shown in the present disclosure. In addition, the skateboard 900 may include a wheel hub (e.g., Figure 8 One or more wheels 920 are provided on opposite sides of the axle 840 of the vehicle. One or more motion sensors 981 (e.g., gears, camshafts, sprockets, and / or pulleys) can be fixed to the axle and configured to rotate with the one or more wheels 920. The one or more wheels 920 can be fixed to rotation with each other, or can rotate independently of each other. Thus, the assembly can include a motion sensor 981 for each wheel 920, and the rotation of each motion sensor 981 can be fixed to and / or correspond to a particular wheel 920.

[0070] One or more motor mounts 982 may be secured to the axle (e.g., to a spacer such as Figure 1 The motor bracket 982 may be fixed to prevent rotation and may remain stationary relative to the axle and / or one or more motion sensors 981. The motor bracket 982 may be mounted adjacent to each motion sensor 981.

[0071] The motor 983 may be fixed to each motor bracket 982. The motor 983 may have a frame that accommodates the electric components. The motor 983 may be an electric motor, but the present disclosure contemplates the use of various types of motors. The motor 983 may include a rotor that rotates and moves during the operation of the motor 983. The rotor may extend outward from the frame. A motion sensor (e.g., a gear, a camshaft, a sprocket and / or a pulley) may be fixed to the rotor, which extends from the frame. The motor 983 may be fixed to the motor bracket 982 so that the motion sensor of the motor 983 is aligned or substantially aligned with the motion sensor 981.

[0072] Motion sensor 981 may directly contact the motion sensor of motor 983. Motion sensor 981 may be spaced apart from the motion sensor of motor 983, and a ring 984 (e.g., a belt, chain, or other interconnection device) may extend from motion sensor 981 to the motion sensor of motor 983 to create an interconnection. Motor 983 may provide power to rotate wheel 920. When activated, the rotor of motor 983 may rotate. This rotation may be transmitted to the motion sensor of motor 983 (e.g., rotating the motion sensor). The rotational motion of the motion sensor may be transmitted directly to motion sensor 981 or indirectly transmitted through ring 984 (e.g., rotating motion sensor 981). When the relative rotation of wheel 920 and motion sensor 981 is fixed, the rotation of motion sensor 981 may cause wheel 920 to rotate accordingly.

[0073] By using different sizes of motion transmission devices (e.g., using a gearbox), the rotation generated by motor 983 can be accelerated and / or decelerated. The motion transmission device of motor 983 may be relatively small, while motion transmission device 981 may be relatively large. Therefore, one complete rotation of the rotor of motor 983 may correspond to less than one complete rotation of wheel 920 (e.g., reducing the rotation speed). Other configurations are contemplated by this disclosure.

[0074] One or more stabilizers 985 may be used to further stabilize and prevent relative movement of the motor 983 and / or motor bracket 982. The stabilizer 985 is illustrated as extending between a first motor bracket 982 and a second motor bracket (not numbered), but other configurations may be used to achieve greater stability of the motor 983 and / or motor bracket 982.

[0075] One or more batteries may be secured to the skateboard 900. One or more batteries may be secured to the panel 910 of the skateboard 900 (e.g., the bottom surface of the panel 910). Wires may be used to electrically couple the one or more motors 983 to the one or more batteries 986 to provide electrical energy to power the one or more motors 983.

Therefore, this specification and the embodiments shown are only for example.
