Technical Field

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

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 the high position of a ski slope, and when the skier slides to the lower end of the ski slope, the skier needs to ride the cable car again and again. In addition, in case of field alpine skiing, a cable car is not usually erected, a skier needs to climb to a high place to start skiing with a ski, and the climbing is a very labor-consuming and physical-consuming process, so that the skier cannot fully enjoy the fun of skiing.

Even in the case of a cable car, the lower end of the ski run is usually spaced a certain distance from the cable car station, and thus, carrying a ski to ride the cable car also has a problem of being laborious and cumbersome. 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.

According to one aspect of the present invention, there is provided a self-walking snowboard, which includes a snowboard body and a driving mechanism provided on the snowboard body, the driving mechanism including a driver, a running gear driven by the driver, the running gear including, for example, a track or a wheel, and the driver being openable by receiving an instruction of a skier to drive the running gear, thereby driving the snowboard to run.

By using the invention, a skier can be carried to the high place of a snow road or the high place of a snow mountain by the skis, so that the requirement that the skier carries the skis to ride a cable car or climb by oneself can be avoided, and the skier can fully enjoy the freedom and the fun brought by the skiing.

In addition, according to the snowboard of the present invention, it is possible to convert the movement of the snowboard into electricity, i.e., to perform reverse charging using energy for deceleration (braking) by snow scraping in the original snowboard movement, for the recovery of braking energy.

Detailed Description

The present invention provides a self-walking snowboard, which includes a snowboard body and a driving mechanism provided on the snowboard body, the driving mechanism includes a driver, which may be constituted by a motor/generator, and an output shaft of the driver is connected with a walking device, thereby driving the driving mechanism to operate. The drive mechanism comprises, for example, tracks or wheels, and is preferably a track. When the skier needs to reach the high or top of the snow road from the bottom or bottom of the snow road, the driver may drive the operation of the running gear according to the received command of the skier, the operation of the running gear enables the skier to run, and preferably the skier can be carried to run to the top or top of the snow road with the skier standing on the ski.

According to the invention, the requirements of taking a cable car or climbing are saved, and the physical strength or cost of a skier is saved, so that the skiing experience is further improved.

Hereinafter, a self-walking snowboard according to the present invention will be described in detail with reference to the accompanying drawings, and 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 only defined by the appended claims and equivalents thereof.

FIG. 1 is a perspective view showing a self-walking snowboard according to a preferred embodiment of the present invention, and FIG. 2 is a schematic view showing a snowshoe mounting bracket; FIG. 3 is a partial view of the self-walking snowboard of FIG. 1 showing an adjustable drive motor mounting arrangement; and FIGS. 4A to 4C are side views of the snowboard showing the drive mechanism in different positions, respectively.

As shown in fig. 1, the self-walking snowboard according to the preferred embodiment of the present invention is a snowboard for snowboarding, but the present invention is not limited thereto and can be applied to a snowboard for snowboarding with two boards. As shown in fig. 1, the snowboard includes a snowboard main body 1, on which two snowshoe supports 2 are provided spaced apart in a longitudinal direction on the snowboard main body 1. The snowshoe stand 2 includes a plurality of snowboard mounting apertures 21 and a plurality of snowshoe mounting apertures 22. The snowboard binding holes 21 are used to bind the snowshoe binding 2 to a snowboard, and the snowshoe binding holes 22 are used to connect with a snowboard boot. The skier's ski boot (not shown) may be detachably secured to the snowshoe support 2, for example by screw fastening or by clips or the like. Where the ski boot is a detachable ski boot as disclosed in PCT/CN2017.076921 or PCT/CN2018/102522 by the present applicant, an outer boot or shell, which may be a ski boot, is secured to the ski boot support 2.

In the middle of the snowshoe support 2, two sensors 23 are provided, said two sensors 23 protruding slightly from the snowshoe support 2, for example by about 1mm, whereby the inclination of the skier can be sensed. The two sensors 23 are, for example, micro-switches, whereby when the skier's foot is moved or forced in different directions, the respective micro-switch is closed, thereby providing a signal to the controller. Based on the signal, the controller may sense the movement of the foot of the skier.

As an alternative embodiment, other forms of snowshoe stands (not shown) may be used, for example, the snowshoe stand may include a support plate that is supported on the snowboard, for example, by struts. The support plate is formed of a material having a certain elasticity, such as a spring steel sheet, so that in the case where a skier stands on a ski, the skier's feet can move or exert force in a certain range and direction, for example, upward or rotational in the front, rear, left, and right directions. In case of detecting the movement or exertion of a specific foot of the skier, a sensing device may be provided on the support plate to sense the movement of the skier. As an example, for example, a stress sensor is attached to the lower surface of the support plate, the stress sensor may be in a radial shape and spaced apart in the circumferential direction, whereby deformation of the support plate may be sensed by the stress sensor, the deformation being transmitted to the controller in the form of an electrical signal, and the controller receives the output of the stress sensor to determine the movement of the skier. Additionally, stress sensors may additionally or alternatively be provided on the support plate in a spiral pattern to sense rotation of the skier's body simultaneously or separately.

The sensing means is not limited to a stress sensor and alternatively micro switches may be provided at a plurality of positions below the support plate, whereby deformation of the support plate triggers the micro switches, the switch state of which micro switches may be received by the controller, and the controller determines the activity of the skier in dependence on the state of each micro switch. However, the present invention is not limited thereto, and the sensing means may also employ a magnetic or optical sensor to detect the movement of the support plate or the skier.

A drive mechanism 3 is further provided on the snowboard main body 1, and the drive mechanism 3 will be described in detail below with reference to fig. 1, 3 to 4C. In the width direction of the snowboard, two driving mechanisms 3 are arranged side by side, and the driving mechanisms 3 are preferably arranged near the side of the snowboard main body 1 so as not to interfere with the movement of the skier. Since the two drive mechanisms 3 are identical, only one drive mechanism 3 will be described below, and the description applies equally to the other drive mechanism 3.

The drive mechanism 3 comprises two drivers 31 and 32 arranged spaced apart in the longitudinal direction of the snowboard, which drivers 31 and 32 may comprise a motor and a drive wheel, and in a preferred construction the motor and the drive wheel are formed in one piece, and the outer peripheral surfaces of the drive wheels 31 and 32 are formed with teeth for driving the endless track 33. The drive wheel is, for example, an in-wheel direct current motor, the stator of which is provided integrally with the wheel shaft of the drive wheel and the rotor is provided integrally with the wheel rim of the drive wheel, whereby the wheel rim rotates around the wheel shaft when energized; when the wheel edge of the drive wheel is driven by the track, the drive wheel constitutes a generator for charging the battery. Thus, in the present description and in the claims, the drive wheel and the drive can be used interchangeably.

The crawler belt 33 is wound annularly around the two drive wheels 31 and 32, and is driven by the above-described drive wheels 31 and 32 as described above.

The snowboard main body 1 is formed with a through opening at a corresponding position so that the crawler belt 33 and the driving wheels 32 can pass under the snowboard main body 1, whereby, as shown in fig. 1, the crawler belt 33 goes under the snowboard main body 1 bypassing the driving wheels 32 and the opening and passes over the snowboard main body 1 from the opening provided near the other end, thereby forming an annular track structure.

Fig. 3 shows a mounting structure of one of the driving wheels 31 and 32, and since the driving wheels 31 and 32 are in a mirror image relationship, only the mounting structure of one of the driving wheels 32 will be described in detail below.

Mounting structures for the drive wheels 32 are provided near both longitudinal ends of the snowboard main body 1. The mounting structure comprises a bracket 39, which bracket 39 is fixed to the ski body 1, and an adjustment handle 35 is pivotally mounted on the bracket 39, e.g. by means of a shaft 39, which adjustment handle 35 is fixed to a fixed part of the drive wheel 32, e.g. by means of a pin 38, whereby the height of the drive wheel 32 relative to the ski body 1 can be adjusted as the adjustment handle 35 is pivoted about the shaft 39. Also provided on the snowboard body 1 is a fixed adjustment mount 34, the fixed adjustment mount 34 comprising two spaced apart and parallel extending arcuate limb portions 342 and 343 forming an arcuate opening therebetween so that a front end rail portion of the adjustment handle 35 can be inserted into and moved within the arcuate opening. A plurality of blocking portions, for example, three blocking portions 341, are provided at the inner circumference of one of the branch portions to fix the adjustment handle 35 at a corresponding position, thereby maintaining the driving wheel 32 at a specific height with respect to the snowboard main body 1.

As shown in fig. 3, the snowboard's two-sided drive mechanisms share the adjustment handle 35 in a set of drive wheel mounting structures, i.e. the adjustment handle 35 can simultaneously adjust the height of the drive wheels of the snowboard's two-sided drive mechanisms relative to the snowboard's main body, and in this case, also only one fixed adjustment seat 34 needs to be provided to determine the position of the adjustment handle 35 for both the left and right drive mechanisms. However, the present invention is not limited thereto, and a set of the mounting structure and the position adjusting structure may be provided separately for the driving mechanism of each side.

Fig. 4A, 4B and 4C show another alternative drive wheel mounting arrangement. As shown in fig. 4A and 4B, the drive wheel 32 is provided on an adjustment handle 35 ', which, like the adjustment handle 35, 35' may be pivotally mounted to the snowboard body 1 via a bracket (not shown in fig. 4A and 4B). The fixed adjustment mount 34 ' includes two arcuate branch portions 342 ' and 343 ' spaced apart and parallel to each other, forming an opening therebetween into which a ledge portion (not numbered) of the adjustment handle 35 ' is inserted and moves as the adjustment handle 35 ' is pivoted. A positioning pin 344 'is provided on a crosspiece portion of the adjustment handle 35'. An adjustment slide in the form of a slot is formed in the outer arcuate limb portion 342 'of the fixed adjustment mount 34', through which slot a pin 344 'passes and through a through hole provided in the crosspiece portion of the adjustment handle 35', and which pin can be biased, for example by a spring, in the direction of the adjustment handle. In the other arcuate limb portion 342 ' of the fixed adjustment mount 34 ', at a plurality of spaced locations along its arcuate shape, there are provided detent holes (not shown) through which the pins 344 ' can extend through the rail portion into the detent holes when the detent holes are aligned with the through holes in the rail portion, thereby securing the rail portion of the adjustment handle and thus the adjustment handle in that position (see fig. 4B).

In addition, as can be seen from fig. 1, in order to facilitate the track 33 to be driven more smoothly, pinch rollers 37 may be further provided at the rotational axis of the bracket 39 to press and guide the track 33.

Fig. 5A to 5C show side views of the driving wheels 32 in different height positions, respectively, wherein fig. 5A is a lifting position in which the driving wheels 32 are fully lifted to the upper part of the ski body 1, so that the lower side of the ski is substantially flush with the lower part of the tracks; figure 5B shows the drive wheel 32 in a neutral position in which the drive wheel 32 and the track 33 protrude from the underside of the ski by a distance of, for example, 2-3 mm. The location is mainly for snow tracks in ski fields or snow tracks where the snow is not very thick; figure 5C shows the lowest position in which the drive wheels 32 and the tracks 33 protrude a large distance, for example 5-6mm, from the underside of the snowboard, mainly for relatively loose or thick snow.

In addition, a battery and controller module 4 is also provided on the snowboard body 1, the battery and controller module 4 including a battery that supplies power to the driving wheels and a controller that controls the operation of the entire automated walking snowboard.

The operation of the self-walking snowboard of the present invention will now be briefly described.

When the skier needs to travel to the high of the snow road, he/she can set the driving wheels 32 at a proper position, for example, a middle position, in which the crawler belts 33 will be protruded under the lower side of the ski, using the adjustment handles 32 according to the situation of the snow road, in which case the skier stands on the ski and inclines his/her body to a specific side. The controller senses the inclination of the skier's body through sensors provided on the snowshoe support 2, and thus activates the drive wheels 32 according to a preset program, at which time the batteries supply power to the drive wheels 32, whereby the drive wheels 32 drive the tracks 33 to move in a circular motion, thereby driving the snowboard to travel high on the snow road.

In the event that the ski has traveled high on the snow track, the skier may return the body to an upright or other position, whereby the sensors in the snowshoe mounts sense changes in the skier's body position, and signal the controller, which upon receiving this signal, stops the drive to the drive wheels 32. The skier can then perform the skiing movement as with a normal ski, i.e. riding the ski to slide down from the high level of the snow track at a high speed, during which the tracks 33 will passively rotate by means of friction between the tracks 33 and the surface of the snow track, whereby the rotation of the tracks 33 will drive the driving wheels 32 to rotate, at which point the driving wheels 32 can act as generators, charging the batteries, thereby converting the energy of the movement of the ski into electrical energy.

In the case where the skier skis in the field where the snow is thick or loose, the skier can set the driving wheel 32 to the lowest position where the driving wheel 32 and the crawler 33 maximally protrude downward from the lower side of the ski, whereby more attachment ability can be provided to climb up with the skier.

In case of reaching a snow road or a mountain peak, the skier can also adjust the driving wheels 32 and the crawler belts 33 to the lifting position according to his own preference, in which case the crawler belts 33 will be driven to rotate with little or no help of friction, whereby the driving wheels 32 generate less power, but in which case the performance of the ski is substantially the same as that of a normal ski.

While preferred embodiments in accordance with the invention have been described above, it will be appreciated by those skilled in the art that a variety of different embodiments may be provided to achieve the same functionality based on the teachings of the present invention.

In the embodiment described above, the activation of the drive wheel 32 is based on the sensors in the snowshoe support sensing the physical action of the skier, however, other means may be employed. For example, the snowshoe support is simply a support plate fixed to the snowboard, and no sensor is provided therein, and the activation of the drive wheel 32 is controlled by a remote control held by the skier or built into the ski wear, gloves, pole, etc., in which case the controller receives the command and controls the drive wheel 32 to start or stop in accordance with the command issued by the skier. The remote control may also be implemented by an application in the skier's smart phone.

In the above embodiment, the case where the snowboard includes two drive mechanisms each including the two drive wheels 31 and 32 has been described, but it is also possible to include only one drive wheel 31 in each drive mechanism, with the other drive wheel 32 being a driven wheel, functioning as the guide track 33; alternatively, a plurality of drive wheels may be provided in each drive mechanism, for example, a third drive wheel may be added in the middle of the two drive wheels 31 and 32, the addition of which may increase the driving ability of the snowboard.

In the above-described embodiment, the form of the drive wheel plus the crawler is adopted, but it is also possible to include only the drive wheel, and omit the crawler, and the drive wheel may be provided as the drive wheel, including a rough outer peripheral surface, thereby improving the adhesion capability with the snow road surface. In this case, a plurality of drive wheels may be provided, for example, three or more drive wheels may be provided on each side.

As an alternative, the adjustment handle 35 of the driving wheel 32 may also be adjusted in an automatic manner, for example by providing a biasing means on the mounting arm of the driving wheel 32 to bias the driving wheel 32 towards the underside of the snowboard, whereby the driving wheel 32 may be extended from the underside of the snowboard a suitable distance, adaptive to the thickness of the snow cover of the snow track, by suitably setting the magnitude of the biasing force of the biasing means.

As an alternative embodiment, the driving wheel 32 may also be adjusted electrically, for example, in case of a remote control, for example, in case the remote control is an application in a smartphone, an option or menu for setting the position of the driving wheel 32 in the application may be provided, whereby the distance the driving wheel 32 extends downwards is automatically adjusted by the skier selecting the corresponding position option in the application.

In addition, the controller may also be provided with a transmission module that can transmit the data of the snowboard to an application, such as a smartphone, for the skier to check. The data may include the remaining charge of the battery, the distance the snowboard has traveled, the geographical location of the snowboard, etc.

In addition, in the above embodiments, a single-board snowboard is described as an example, but it is conceivable for those skilled in the art that the present invention can also be applied to a snowboard for two-board skiing.

Snowboards for two-board skiing typically comprise two snowboards, only one of which is shown in fig. 6, and it will be understood by those skilled in the art that the other may be the same as shown in fig. 6.

As shown in fig. 6, the snowboard includes a snowboard main body 1, driving mechanisms 3 provided near both ends of the snowboard main body 1 in the longitudinal direction, respectively, and a position for attaching a snowshoe binding provided at a substantially middle position of the snowboard main body 1.

Figure 7 shows an enlarged perspective view of one of the drive mechanisms 3. the drive mechanism 3 may adopt the structure shown above with reference to figure 3 or figures 4A-4C, except that the span of the drive mechanism 3 is not the length of the entire ski body, but only a part near one end of the ski body, whereas the other drive mechanism 3 is provided near the other end of the ski body. However, this is not essential, and only one drive mechanism may be provided. Thus, for the sake of brevity, the description above with reference to fig. 3 and 4A-4C may be equally applicable to the drive mechanism herein and will not be repeated here.

It is further noted that since in snowboarding the skiers 'snowshoes are fixed to the ski bindings, the skiers' instructions can be issued via a remote control, which can be built into any of the skiers 'ski poles, ski wear, ski gloves, goggles, helmets, etc., or alternatively, the remote control can be implemented using an application in the skiers' smart phone.
