Description

Automatic walking skis

This application claims priority from chinese patent application No. 201910345131.6 entitled "self-walking snowboard" filed on 26.4.2019, which is incorporated herein by reference in its entirety.

Technical Field

The present invention relates to snowboards, and more particularly to snowboards having a travel drive assembly.

Background

Skiing is a very popular winter sport where the skier relies on the ski to quickly slide off a mountain, thereby providing a feeling of excitement. However, before starting skiing, in a ski field, a skier needs to ride a cable car to reach a high position of a ski slope and, when enjoying a stimulus of skiing and sliding to a lower end of the ski slope, needs to ride the cable car again and again. In addition, in the field where the cable car is not installed, if a user wants to ski, the user needs to climb to a high place with the ski to start skiing, and the skiing is a very labor-consuming and physical-energy-consuming process, so that the user cannot fully enjoy the fun of skiing.

Even in the case of a cable car, the parking lot is generally spaced apart from the lower end of the ski run and the cable car station by a certain distance, and thus, there is also a problem of great effort and complication in carrying a ski to board the cable car. In addition, boarding the cable car requires a certain cost, which causes inconvenience in skiing.

Disclosure of Invention

According to the present invention, there is provided a self-walking ski whereby a skier can ride the self-walking ski to a high place of a snow road or a mountain without riding a cable car or climbing as usual.

The invention provides a self-walking snowboard, which comprises a snowboard body and a driving mechanism or a driving assembly arranged on the snowboard body. The drive mechanism comprises, for example, tracks or wheels, and is preferably a track. The drive assembly is operable in response to receipt of a command from the skier when the skier needs to reach the high or top of the snow track from the bottom or bottom of the snow track, the operation of the drive mechanism enabling the ski to walk and preferably to carry the skier to walk to the top or top of the snow track while the skier is standing on the ski.

According to the present invention, there is provided a self-walking ski including skis and at least one driving assembly provided on each ski, the driving assembly being switchable between a drive-walking state in which the driving assembly is provided at a lower side of the ski to drive the ski to travel and a skiing state in which the driving assembly is provided at an upper side of the ski to allow a skier to perform skiing motions using the ski.

Wherein there may further be included a universal wheel or snow foil, optionally arranged on the snowboard together with the drive assembly, such that in the driveable walking state the universal wheel or snow foil is arranged on the underside of each snowboard at a distance from the drive assembly along the length of the snowboard, and preferably the snow foil or universal wheel is arranged near the longitudinal front end of the snowboard, while in the drive assembly arrangement near the longitudinal rear end of the snowboard, and in the skiing state the universal wheel or snow foil is arranged on the upper side of the snowboard at a distance from the drive assembly along the length of the snowboard.

Alternatively, each ski is provided with two drive assemblies, which in the drive-walking state are arranged at a distance along the length of the ski on the lower side of the ski, and in the skiing state are arranged at a distance along the length of the ski on the upper side of the ski.

Thus, by providing a combination of a plurality of accessories such as universal wheels, snow deflectors, drive units, etc., the skier can freely select an appropriate arrangement according to the road surface conditions, so that the ski according to the present invention can cope with various road surface conditions. For example, the arrangement of universal wheels plus drive assemblies may be suitable for use in road mode, the arrangement of snow horns plus drive assemblies may be suitable for wet road surfaces such as snow and ice, and the four-wheel drive mode with two drive assemblies per snowboard may be suitable for more severe road conditions.

The drive assembly, the universal wheel and the snow guide plate respectively comprise a clamping mechanism, and the drive assembly, the universal wheel and the snow guide plate are clamped on the snowboard through the clamping mechanism. Thus, the drive unit, the universal wheels and the snowboard can be easily clamped to the lower side of the snowboard to be in a driving state, and can be easily disassembled from the snowboard to be clamped to the upper side of the snowboard to be in a skiing state.

The snowboard further includes a binding provided on an upper side of the snowboard for holding a boot of a snowman, and storage frames respectively fixed to front and rear ends of the binding of the snowboard, so that the driving assembly, the universal wheels or the snow guide plate is clamped to the storage frames by the clamping mechanism in the skiing state, thereby being brought into the skiing state.

Preferably, the drive assembly includes a track, a drive motor assembly that drives the track, and a controller that controls operation of the drive motor assembly.

The controller is configured to receive instructions from a remote control to control the drive motor assembly to drive the tracks, thereby driving the self-walking snowboard to travel.

Preferably, the remote control is formed integrally with the handle of the ski pole of the skier; or the remote control may be a separate remote control.

In the case of two-board skiing, two skis may be included, and at least one interconnection link interconnecting the two skis in the drive-walking state.

The controllers of the snowboard driving assemblies are configured to receive control commands from the two controllers respectively so as to control the driving assembly of each snowboard individually; alternatively, only one remote controller can be provided, so that the driving components under the left snowboard and the right snowboard are controlled to be synchronously driven, and the directional control of turning, turning around and the like is realized.

The controller is configured to receive instructions from the ground base station to control operation of the drive assembly in accordance with the instructions. Preferably, when a danger signal from a safety control system of the base station is received and a danger control is performed, for example, a skier may be in an expected track of an uncontrolled skier or a hill top rock, the controller is configured to perform avoidance operations such as a whistle warning, taking over steering, braking, and the like according to the danger signal, so as to actively avoid the dangerous uncontrolled skier or the hill top rock.

The invention adopts a modular design, can freely combine with any snowboard at present for climbing mountains and sliding down, and can select various accessories according to requirements to realize various configurations such as two-wheel drive, four-wheel drive, range extension and the like. In addition, the driving mode for climbing the mountain and the mode for sliding down are freely switched, and the switching can be easily finished within tens of seconds;

the automatic walking skis can be controlled to steer in time through actions, ski poles or a single remote controller respectively, or the actions, the ski poles and the single remote controller are combined to control steering. All manipulations are basically consistent with the past skiing habits;

under the driving mode, the system can be linked with a ground base station to realize collision early warning, active avoidance, braking and the like.

The invention also brings the following benefits compared to prior art snowboards:

not only does not change any structure of the prior snowboard, completely keeps the whole performance of the traditional snowboard, but also is the same as the common snowboard in the aspect of operation, therefore, the snowboard can be easily used by skiers without special skills.

Under the driving walking (climbing) state, a larger pressure area, a larger driving force or a longer endurance mileage can be obtained by freely combining different driving components. Even in the open-air snowfield without rolling and under the load, even on the steep slope, the snow is unobstructed.

The mode can be changed into the downhill mode, namely the skiing state, through simple combination of dozens of seconds.

The standby power supply supporting long-endurance backpack type can be configured, so that driving at a longer distance is realized.

According to the invention, the cable car is not used for taking or climbing, the physical strength or the cost of a skier is saved, and the skiing experience is further improved.

Detailed Description

Hereinafter, a self-walking snowboard according to the present invention will be described in detail with reference to the accompanying drawings. It is noted that in the following description, the present invention is explained and explained in detail by taking a two-board snowboard as an example, but those skilled in the art will appreciate that the present invention is not limited thereto but can be applied to a one-board snowboard or the like.

In the following description, directional terms such as "front", "rear", "upper" and "lower" are used for convenience of understanding, and the present invention should not be limited thereto. Generally speaking, "front" is described with reference to the direction of a snowboard, in the case of normal skiing, the tip of the snowboard that tips up is pointed in a forward or forward direction, and "rear" is the direction along the length of the snowboard opposite to that indicated by "front", lower in describing the part being closer to the ground or snow track, and upper in the direction opposite to "lower".

Fig. 1 and 2 show operational state diagrams of one configuration of a self-walking snowboard according to the present invention, in which fig. 1 shows a state of the snowboard in a walking driving mode, and fig. 2 shows a state of sliding the snowboard in a skiing state.

As shown in fig. 1, the self-walking snowboard 100 according to the present invention is a snowboard for two-board skiing, including two snowboards. Since the structures of the two skis are mirror images, one of the skis will be described in detail below, and the structure of the ski can be equally applied to the other ski. The snowboard includes a snowboard main body 110, the snowboard main body 110 being the same as a general snowboard, including a board body 111 and a binding 112 provided at a substantially middle position on an upper surface of the board body 111, and a snowboard boot (not shown) may be caught on the binding 112 when skiing.

As further shown in fig. 1, in the walking drive mode, each snowboard further includes a driving assembly 200 mounted on the underside of the board body 111 at the rear end of the board body 111 (the detailed structure of the driving assembly 200 will be described later); a universal wheel 300 fitted on the lower side of the plate body 111 in the vicinity of the front end of the plate body 111 (the structure of the universal wheel 300 will be described in detail later); and receiving racks 400 fastened to the front and rear ends of the holder 112, respectively.

The drive assembly 200 includes a track drive mechanism (described below) and may be controlled, for example, by a remote control. In the state shown in fig. 1, a skier (not shown) can stand on the snowboard by fastening a ski boot (not shown) to the binding 112 of the snowboard and control the driving assembly 200 to drive through a remote controller, thereby advancing and retreating. And, steering is achieved by controlling the speed of the drive assemblies 200 of both skis or by tilting the body.

To facilitate control and to improve stability, as shown in FIG. 1, a plurality of interconnecting links 500 may be included, the interconnecting links 500 interconnecting two skis together (the specific operation described below), thereby improving stability throughout the drive process. It is to be understood, however, that the interconnecting link 500 is not necessary and that it is possible for a skilled skier to omit the interconnecting link 500 and control both skis with good coordination ability.

Thus, the skier can step on the ski 100 to the designated location under the drive of the drive assembly. After reaching the specification, the skier can take the driving assembly 200 and the universal wheels 300 off the board body 111 of the ski and fit onto the upper surface of the board body 111 of the ski by means of the aforementioned storage bracket 400, i.e., place the ski in a skiing state and open the interlinking rod 500 using the interlinking rod 500, whereby the skier can ski using the ski as in a general ski.

To accommodate different ground conditions, the self-walking snowboard according to the present invention provides a variety of configurations. For example, the arrangement of fig. 1 and 2 (also referred to as a castor arrangement) is suitable for travel on relatively flat and hard surfaces, while the present invention provides a variety of arrangements for skiers to choose from on icy or snowy or soft, rugged, steep, etc. surfaces.

For example, fig. 3 and 4 show views of a self-walking snowboard according to the present invention adapted to be driven on a slippery road surface such as ice and snow, wherein fig. 3 shows the snowboard in a state of being driven and fig. 4 shows the snowboard in a state of being snowed.

In contrast to fig. 1 and 2, in the configuration of fig. 3 and 4 (also referred to as snow board configuration), the universal wheel 300 of the snowboard front end attachment is replaced by a snow board 600, and the snow board 600 may be similarly mounted on the lower side of the board body 111 of the snowboard in the driving state (as shown in fig. 3) and on the upper side of the board body 111 of the snowboard in the skiing state (as shown in fig. 4), thereby achieving switching between the two states.

In this way, for example, a skier can drive up to the apex of the snow way with the snow guide plate 600 and the driving assembly 200 assembled on the lower side of the snowboard's plate body 111, and after reaching the apex of the snow way, can remove the snow guide plate 600 and the driving assembly 200 from the lower side of the plate body 111 and clamp on the upper side of the plate body 111, thereby performing a skiing exercise like a general snowboard.

Similarly, between the two skis, the two skis may optionally be interconnected using an interconnecting link 500, thereby improving stability while walking.

Fig. 5 and 6 show the configuration adopted on difficult paths such as rough, soft, steep, etc., also called the four-wheel drive configuration, where fig. 5 shows the snowboard in the driving walking state and fig. 6 shows the snowboard in the skiing state.

As shown in fig. 5, it is different from fig. 1 and 3 in that driving units 200 are mounted on the lower side of the plate body 111 of each snowboard near the front end and near the rear end, respectively, so that each snowboard can be driven simultaneously by two driving units 200, and the other snowboard is also driven simultaneously by two driving units 200, whereby the entire self-walking snowboard can be driven by four driving units 200 to act, providing greater driving ability, so that it can cope with various difficult road conditions.

As shown in fig. 6, after reaching a skiing start point such as a mountain top, a skier may mount the driving assembly 200 on the upper side of the plate body 111, thereby freely skiing like a general snowboard.

In addition, as shown in FIG. 6, since two drive assemblies 200 are provided in front and rear of each snowboard, a plurality of interconnection links 500 are provided at their connection points, so that the interconnection links 500 can be connected with a greater span as shown in FIG. 6, providing greater stability.

Hereinafter, the structures of the respective components employed in the self-walking snowboard according to the present invention will be described in detail with reference to the accompanying drawings.

The universal wheel 300:

the universal wheel 300 fitted near the front end of the plate body 111 will be described in detail with reference to fig. 7.

As shown in fig. 7, the universal wheel 300 includes a bracket 301, a wheel frame 310 swingable along a vertical axis 309, a wheel 301 rotatably mounted to the wheel frame 310 by means of a shaft (not numbered), and a chucking mechanism provided on the bracket 301.

The catch mechanism comprises catches 303 and 303' secured to laterally opposite sides of the bracket 301, each catch 303 being secured at one end to the bracket 301, for example by riveting, and projecting upwardly at the other end to catch on both side edges of the ski body 111, the projecting ends being bendable towards each other, for example by approximately 10 to 15 degrees, in order to facilitate catching of the ski body.

The bracket 302 is made of, for example, a metal material, and has a certain elasticity. The catch mechanism also includes a load binder that spans laterally between the two jaws 303 and 303 ' to pull the jaws 303 and 303 ' toward each other or to push the jaws 303 and 303 ' away from each other. The locker includes a first lock lever 305, a second lock lever 308, and a lock handle 304 pivotably coupled to the first and second lock levers, respectively. As shown in fig. 7, the first locking lever 305 is connected to the first jaw 303, for example, by a link 310, the second locking lever 308 is connected to the second jaw 303 ', the first locking lever 305 is pivotally connected to the locking handle 304 at a first pivot point 306, and the second locking lever 308 is pivotally connected to the locking handle 304 at a second pivot point 307, and the first pivot point 306 and the second pivot point 307 are spaced apart from each other, whereby, when the locking handle 304 is rotated, for example, in a counterclockwise direction (the direction indicated by the arrow a in fig. 7) in fig. 7, the locking handle 304 pushes the two jaws 303 and 303' outward, respectively, whereby the universal wheel 300 can be fastened to or removed from the opposite outer edges of the snowboard's board body 111, and then by rotating the locking handle 304 in a direction opposite to the direction indicated by the arrow a, the locking handle 304 pulls the two jaws 303 and 303' inward, respectively, through the first and second pivot points 306 and 307, respectively, thereby clamping the universal wheel 300 to the opposite outer edges of the plate body 111. Meanwhile, the lower surface of the plate body 111 may abut on the upper edge of the bracket 302 to stably support the plate body 111 of the snowboard through the universal wheel 300.

Thus, the universal wheel 300 can be conveniently clamped to the snowboard by the clamping mechanism as described above, and when a desired place is reached, the clamping mechanism can be easily released by the locking handle 304, the universal wheel 300 is removed from the board body 111 of the snowboard and left on the upper side of the board body 111 of the snowboard (see fig. 2), and the locking handle 304 is locked, whereby the universal wheel 300 can be clamped on the upper side of the board body 111 without hindering the snowboarder from performing a skiing exercise. The caster wheel 300 is generally suitable for use on relatively hard surfaces, such as hard asphalt or hard sand, gravel, and may be used to carry skiers from a parking lot to a cableway station, for example.

Snow guide plate 600:

as shown in fig. 3 and 4, the universal wheel 300 may be replaced with a snow guard 600 on a wet road surface such as ice and snow.

Fig. 8 shows a perspective view of the snow deflector 600. As shown in fig. 8, the snow horn 600 includes a snow horn body 605, the snow horn body 605 having a smooth bottom surface and a front end slightly raised like the front portion of the plate body 111 of the snowboard to facilitate traveling on the ice and snow road surface. In addition, in order to reinforce the main body 605, a reinforcing rib 606 may be formed on the upper surface of the snow guide plate main body 605 along the longitudinal direction (longitudinal direction).

Two brackets, including a front bracket 601 and a rear bracket 602, are respectively provided on the upper side of the snow guide plate body 605, and the two

brackets

601 and 602 are substantially in the shape of a groove and are formed by bending, for example, a metal plate material.

A stepped portion 6012 is formed at the top ends of the two branches of the front bracket 601 to provide support for the snowboard 600 when it is clamped on the snowboard's plate body 111. The claws 6011 extend upward from the step portion 6012, and the claws 6011 may be inclined inward (facing each other), for example, 10 to 15 degrees, so as to be caught on the opposite side edges of the plate body of the snowboard. A locker 603 is disposed between the two branches of the bracket 601, and the structure of the locker 603 is the same as that of the locker of the universal wheel 300 described above, and thus, the description thereof is omitted. Wherein, the locker is in a locked state.

By means of the elasticity of the two branches of the front bracket 601, the locker can tighten the two branches and thus the jaws 6011 so that the snow guiding plate 600 can be clamped near the front end of the snowboard, and in addition, by rotating the locking handle of the locker in reverse, the two jaws 6011 of the front bracket 601 can be opened, so that the snow guiding plate 600 can be easily released from the body of the snowboard.

The rear bracket 602 is similar in structure to the front bracket 601, includes a similar groove shape, and includes a locker 604, wherein the locker 604 is in an open state. And therefore, the same parts will not be described in detail herein.

The difference from the front bracket 601 is that the rear bracket 602 is further provided with a roller 607 between the two branches, the roller 607 is rotatably provided between the two branches by a shaft (not labeled), and the snow guide plate main body 605 is provided with an opening 608 at a position corresponding to the roller 607 so that the roller 607 can protrude below the snow guide plate main body 605 through the opening 608. Therefore, the roller 607 is arranged on the snow guide plate 600, the snow guide plate 600 can get over small bumps, bulges or pits, the passing capacity of the snow guide plate 600 is improved, and the snow guide plate can replace universal wheels to be used for multiple purposes on a flat road surface. However, the roller 607 is not essential and may be omitted so that the snow horn 600 may be equally well slid on the ice and snow road surface.

The driving assembly 200:

as shown in fig. 1 to 6, the plate body 111 of each snowboard may be provided with at least one driving assembly 200, and the driving assembly 200 may be disposed on the lower side of the plate body 111 in a walking driving state to drive the snowboard to advance, and further, the driving assembly 200 may be disposed on the upper side of the body 111 in a skiing state so that the snowboard can be used as a general snowboard.

Referring now to fig. 9 to 12, the structure of the drive assembly 200 will be described in detail, wherein fig. 9 shows a perspective view of the drive assembly 200, and fig. 10 shows a perspective view of the drive assembly 200 from another angle; FIG. 11 shows a side view of the drive assembly with the housing removed to see the structure of the inner plate of the drive assembly; and figure 12 shows an exploded perspective view of the drive assembly.

As shown in fig. 9 to 12, the driving assembly 200 includes a housing 201, and as shown in fig. 12, the housing 201 may be split by two

housing halves

2011 and 2012, and opened at a lower side to expose the track 270. As shown, the split drive assembly 200 is approximately the same width as the snowboard plate 111.

Within the housing 201, near one end of the housing, for example near the rear end, there is provided a drive wheel 210, the outer periphery of which wheel 210 is toothed to engage with the inner surface of the track 270, thereby driving the track 270 in an endless motion. Further, in the housing 201, near the front end of the housing, a guide wheel 220 is provided, and the guide wheel 220 guides the endless movement of the crawler 270. On the bottom of the middle portion of the housing 201, a plurality of load-bearing wheels 230 are provided, the load-bearing wheels 230 being rotatably fixed to both side plates of the housing by means of shafts 231, thereby supporting the weight of the entire drive assembly and the snowboard. In addition, the diameter of the driving wheel 210 is substantially equal to the height of the housing 201, and also plays a role of bearing weight.

Also disposed within the housing 201 is a motor assembly 240 for driving the driving wheel 210 to rotate, the motor assembly 240 including a motor 242, a heat sink 241 fitted around the motor 242 to dissipate heat generated by the motor, and a reducer 245 for transmitting the rotational output of the motor 242 to the driving wheel.

In addition, the driving wheel 210 may be divided into two wheels, which are respectively provided at both sides of the decelerator 245. In order to guide the movement of the track 270, a guide bracket 244 is provided between the two driving wheels 210 at one end of the decelerator 245, and the guide bracket 244 is provided with a plurality of small rollers 246 at the side contacting the track 270, the small rollers 246 being rotatably mounted on the guide bracket 244 by means of the shafts 245, thereby guiding the movement of the track 270 and reducing friction and wear of the track 270.

The guide wheels 220 are mounted to the side plates of the housing 201 by mounting brackets 222, and the mounting brackets 222 include long holes (not labeled) into which shafts of the guide wheels 220 are inserted, so that the positions of the guide wheels 220 can be adjusted along the long holes, thereby adjusting the tension of the crawler 270. A set screw 223 is also provided which can fix the shaft of the guide wheel 220 in the adjusted position.

Thus, the track 270 is pulled over and tensioned by the drive wheel 210, the idler wheel 220, and the plurality of bogie wheels 230. As the drive wheels 210 are driven by the motor assembly 240, the drive wheels 210 may drive the tracks 270 in a circular motion, thereby driving the entire snowboard in motion.

In the space between the motor assembly 240 and the guide wheel 220, a battery compartment 250 is provided in the housing 201, into which compartment 250 a rechargeable battery (not shown) can be inserted, thereby giving the motor assembly 240 a function. On one side of the battery compartment 250, for example, on the side facing the guide wheels 220, a controller 280 is provided, and the controller 280 may control the movement of the entire drive assembly 200.

As described above, the housing 201 is formed by splicing the two

half shells

2011 and 2012, and the two

half shells

2011 and 2012 can be respectively formed by bending a metal plate. In the side and top plates of the case 201, a plurality of openings may be formed to reduce the weight of the entire case and improve heat dissipation conditions. In addition, in the side plates of the housing 201, for example, near the rear ends of the side plates of the half shell 2011, a grip 2013 is formed, and in the opposite position of the half shell 2012, a grip 2014 is formed, the two

grips

2013 and 2014 being opposed to each other and spaced apart by a distance substantially equal to the width of the snowboard. The clamping

portions

2013 and 2014 may be formed by cutting slits in the side plates such that the clamping

portions

2013 and 2014 have a certain elasticity. The top ends of the two clamping

portions

2013 and 2014 respectively form clamping jaws which are inclined towards the middle, the inclination angle is about 10 degrees to 15 degrees, and a locker 260 is arranged between the two clamping

portions

2013 and 2014, the structure of the locker 260 is the same as that of the locker described above, and therefore, the details are not repeated.

At approximately the middle front positions of the opposite side plates of the housing 201,

clamp pieces

2015 and 2016 are respectively provided, the lower ends of the

clamp pieces

2015 and 2016 are fixed to the side plates by riveting, for example, and the upper ends are inclined toward the middle to form a jaw, and the angle of the inclination is approximately 10 to 15 degrees. And between the two

opposite clamp pieces

2015 and 2016, a locker (not labeled) is provided, which has the same structure as the above-mentioned locker, and thus, the description thereof is omitted.

Thus, referring to fig. 1 to 6 and 9 and 10, the entire driving assembly 200 may be clamped to both side edges of the snowboard by the clamping part and the clamping pieces of the driving assembly 200, and thus the driving assembly 200 is disposed at the lower side of the snowboard, and thus the entire snowboard is driven to move by the driving assembly 200.

Storage rack 400:

a storage rack 400 provided on the upper side of the snowboard for storing the drive assembly and the universal wheels or snowboard is described below with reference to fig. 13 to 15. The storage frame 400 is used to fix the above-described driving assembly 200, universal wheels 300, and snow guide plate 600 on the upper side of the plate body 111 of the snowboard, whereby a skier can ski using the snowboard according to the present invention like a general snowboard.

As shown in fig. 1 to 6, two front and rear storage racks 400 are included in the snowboard, and the front and rear storage racks have the same structure, so that only one storage rack 400 is described below.

As shown in fig. 13 to 15, the receiving rack 400 integrally includes two parts, i.e., a holder catching part 410 and a clamping part 420. As can be seen in the sectional view of fig. 14, the holder engaging part 410 includes a guide groove 411 into which the slide rail of the holder 112 can be inserted, and the holder engaging part 410 further includes a locking lever 412 having a circular head 414 at one end and a U-shaped bend 415 formed at the other end to protrude into the guide groove 411, and a spring 413 is further provided between the circular head 414 and the body of the holder engaging part 410 to bias the circular head such that the bent end 415 is biased toward the inside of the guide groove 411 such that the bent end 415 presses against the slide rail when the slide rail of the holder 112 is inserted into the guide groove 411 of the holder engaging part 410 and is in place, thereby holding the receiving frame 400 on the holder 112. To enhance the securing action, the bent end 415 may have a pointed tip. By pressing on the rounded head 414, the end 415 can be retracted so that the storage rack 400 can be removed from the snowboard binding 112.

The clamping part 420 is formed of two

parts

421 and 422 which are slidably fitted on the end surface of the holder buckling part 410 by a tenon 430 and can be fitted and slid along the tenon so that the first part 421 and the second part 422 can be moved toward and away from each other. On the sides of the

first parts

421 and 422 facing away from each other, inwardly inclined clamping surfaces 423 are provided, on which clamping surfaces 423 the above-described clamping jaws can be clamped, in order to clamp the drive assembly, the castor wheel or the snow deflector on the receiving rack 400. Further, through-going long grooves 422 (only one is indicated) are provided in the first and

second portions

412 and 422, respectively, and the long grooves 422 extend in the sliding direction. A bolt 424 is also included which is threaded through the slot 422 and onto the retainer snap 410 to fix the position of the first and second portions so that the width between the two clamping surfaces 423 of the first and second portions can be adjusted to fit different universal wheels, snow horns and drive assemblies by adjusting the position at which the first and second portions fit along the dovetail.

In order to fix the positions of the first and second parts, serrations are further provided on the respective opposite surfaces of the first and second parts and the holder fastening part 410, so that the positions of the first and second parts can be more firmly fixed by the bolts 424.

The interconnecting link 500:

to improve stability of the snowboards in the drive-walking state, an interlink 500 may be provided between the two snowboards, and as shown in fig. 1, 3 and 5, the interlink 500 may include two types of interlinks, a short interlink 510 and a long interlink 520 (see fig. 5).

Short interconnecting rod 510 has a right angle bent insertion end 511 at one end and a loop 512 at the other end to fit over a grommet 2017 (fig. 17) on the outside of the housing of the drive assembly. The insertion end 511 may be inserted into an insertion ring also formed at the outer side of the case of the driving assembly 200, the insertion ring including a grommet 2018 and a spring housing 2019 fixed to the lower side of the grommet, whereby, when the insertion end 511 of the short interconnecting bar 510 is inserted into the insertion ring of the driving assembly 200 of another snowboard, a certain amount of swing may be provided to the interconnecting bar 510 while keeping the interconnecting bar 510 interconnecting the two snowboards by the elasticity of the spring housing 2019, thereby providing a certain amount of movement to the two snowboards when the snowboards turn or the ground where the two snowboards are located is uneven.

The long interconnecting rod 520 has insertion ends (not identified) formed at both ends thereof to be inserted into the selected insertion ring. In addition, the spring 521 is included in the middle of the long interconnecting rod 520, and a certain flexibility is provided for the long interconnecting rod 520 through the spring 521, so that the speed difference or the position deviation of two snowboards can be accommodated under the condition that the two snowboards have speed difference, steering and the like.

On the outer side wall of the drive assembly 200, there are also provided a plurality of catches 2020 (only one labeled) for catching the insertion ends of the interconnecting rods, whereby in a state where two skis do not need to be interconnected, for example, in a skiing state, the interconnecting rods can be caught on the outer side wall of the drive assembly 200, thereby not hindering a skier from skiing.

Controller 280 and remote control 700:

as described with reference to fig. 12, the controller 280 may be disposed on one side of the battery compartment and may include circuitry to control the operation of the motor assembly 240. In addition, the controller 280 includes a signal receiving part to receive a signal from the remote controller 700.

As shown in FIG. 18, the remote control 700 is, for example, in the form of a handle 710 of a ski pole, the remainder of which is not shown in FIG. 18. The remote control 700 is held by the skier and includes a control button 720 at the top of the handle 710, the control button 720 being toggled back and forth to control the speed and direction of the drive assembly 200. The remote controller 700 may communicate with the controller 280 and provide control signals to the remote controller 280 in various manners, such as infrared, ultrasonic, microwave, radio, etc., and the present invention is not limited thereto.

For example, when the control button 720 is pushed in the direction indicated by arrow A, the remote control 700 sends a control signal to the controller 280, and the controller 280 receives the control signal and activates the motor assembly 240, thereby driving the entire snowboard to move. The further forward the control button 720 is pushed in the forward-backward direction of arrow a, the faster the motor assembly 240 is operated, and the faster the entire snowboard is moved.

For example, the control button 720 may be pushed in the opposite direction, thereby causing the motor assembly 240 to reverse direction, however, this function may be omitted.

Alternatively, a single remote control may be used to control the snowboard drive assemblies, in which case the remote control 700 may be toggled back and forth and left and right (as indicated by arrows a and B), thereby controlling the snowboard drive assemblies in combination to achieve forward, reverse and left and right steering.

The controller 280 may include a central processing unit, memory and associated I/O interfaces, and the central processing unit may execute programs stored in the memory to control the motor assembly 240 to drive via the I/O interfaces. In addition, the controller 280 may also communicate with and receive signals from or issue commands to other components of the drive assembly via the I/O interface. The controller 280 may be implemented by a general purpose processor or a special purpose processor, or may be implemented by discrete component circuitry, to which the invention is not limited.

The controller 280 may also include a communication module (not shown) that can communicate with other equipment worn by the skier and thus can work with these assemblies. For example, the ski wear in the PCT/CN2017/105381 application is used in conjunction to sense the status of the ski wear and automatically stop driving or send a warning message when the ski wear is triggered by the detection of a dangerous state of the skier.

In addition, it is also possible to communicate with the ski boots disclosed in PCT/CN2018/102522 by the present applicant to sense vital signs or attitude information of the skier to control or change the driving state of the motor assembly 240. For example, in the case where a fall of a skier is sensed, the driving of the motor assembly 240 is automatically stopped.

In addition, the system can also communicate with a base station arranged in a ski field as disclosed in PCT/CN2020/081725 by the applicant, so as to realize functions of collision warning, active avoidance, braking and the like when receiving the condition that an obstacle exists nearby or a runaway skier occurs nearby. In this embodiment, for example, a base station in a ski resort in an arrangement receives a trigger signal from a runaway skier and signals a danger to skiers within a predetermined range from the runaway skier. The danger signal may be received by the snowboard controller 280 of the snowboarders within the predetermined range, the danger signal may contain instructions to control the operation of the drive assembly, and the controller may be configured to interpret the danger signal and control the operation of the drive assembly 200 according to the instructions contained in the danger signal, e.g., control the drive assembly 200 to brake or control the snowboard to steer to avoid the danger. Alternatively, the base station may monitor rockfall or other dangerous conditions on the hill and send a danger signal to a potentially threatening skier when such dangerous conditions occur, and the skier's ski controller 280 may receive the danger signal and interpret the danger signal to perform braking or avoidance (steering).

In addition, the controller 280 may further include a geographical location information sensor, such as a sensor of GPS, beidou, galileo positioning system, to determine the location of the snowboard, and the controller 280 may communicate with a mobile terminal of the skier, such as a cell phone, through its communication module to transmit the location of the snowboard to the cell phone. In the case where the controller 280 includes a geographic position information sensor, the controller 280 may receive the danger signal and calculate whether or not the current skier is within the danger range according to a program stored in the controller 280, and thus perform a countermeasure operation such as braking or avoidance.

In a further embodiment, the controller 280 may receive a route planned by the skier, for example, through an APP within the mobile terminal, to automatically drive or make route corrections based on the location determined by the geographic location sensor and map information stored in memory.

Thus, with the self-walking snowboard according to the present invention, a skier can avoid boarding a cable car to the snow start point, but can control the snowboard to walk to the snow start point by himself or herself. In addition, for different road conditions, the skiers can select different configuration modes, for example, in rugged or steep mountains, the four-wheel drive configuration can be adopted, so that the skis can reach the tops of the mountains, and the difficulty in climbing is avoided. After reaching the origin of the snow track or the top of a hill, the skier can very easily detach and snap the drive assembly or the like onto the upper side of the ski, so that the ski can be used like a normal ski, enjoying the fun of skiing.

In addition, the self-walking snowboard according to the present invention can be quickly transformed into a vehicle by interconnecting rods in addition to carrying the snowboarder itself, can carry a load such as an injured snowboarder or skiing equipment, and can carry the load to a designated place by remote control.

In addition, according to the invention, a charging backpack can be additionally matched, so that additional electric power is provided for the snowboard, and the travel can be further extended.

Under the driving walking (climbing) mode, a larger pressure area, a larger driving force or a longer endurance mileage can be obtained by freely combining different driving components. Even if the snow falls on the ground without rolling and bears a load, even if the snow rises on a steep slope, the snow is smooth and unobstructed.

Although the self-walking snowboard according to the present invention has been described in detail with reference to the specific embodiments, it will be understood by those skilled in the art that the following description is only a preferred embodiment of the self-walking snowboard according to the present invention and the present invention should not be limited thereto but the scope of the present invention is defined only by the appended claims and equivalents thereof.
