Embodiments of the invention

[0044] In order to enable those skilled in the art to better understand the solutions of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0045] Please refer to FIG. 1 to FIG. 3, FIG. 1 is a schematic structural diagram of a first embodiment of a sliding tool provided by the present invention; FIG. 2 is a partial structural schematic diagram of the sliding tool at another angle shown in FIG. 1; Schematic diagram of the sliding tool shown at another angle.

[0046] It should be noted that the tilt setting described herein does not include the case where the two are perpendicular.

[0047] In this embodiment, the taxiing tool includes a main taxiing portion 70 and a driving device.

[0048] Among them, the driving device includes a moving mechanism 10 and a driving portion 20 connected to the moving mechanism 10; the driving portion 20 has a driving end 20a capable of abutting against ice or snow.

[0049] The movement mechanism 10 can drive the driving end 20a of the driving part to abut against and move on the ice or snow, so as to drive the main taxiing part 70 to taxi.

[0050] It should also be noted that, during the driving process, when the sliding end of the main sliding part 70 and the running track of the driving mechanism 20 driven by the movement mechanism 10 are in a plane or direction inclined or perpendicular to each other, and when the driving end 20a When the angle with the sliding end of the main taxiing portion 70 is inclined, the driving portion 20 taxis on the ice surface in the extending direction of its driving end 20a; the main sliding portion 70 taxis in the extending direction of its sliding end.

[0051] In a specific solution, the driving part 20 is a skateboard structure or an ice skate structure or the driving part 20 is a structure for mounting a roller.

[0052] Among them, the relative position between the moving mechanism 10 and the main sliding portion 70 can be adjusted, so as to adjust the plane or direction of the running track of the driving mechanism 20a driven by the moving mechanism 10 and the sliding end of the main sliding portion 70. Angle;

[0053] At the same time, the relative position between the moving mechanism 10 and the driving member 20 is fixed, so that the plane or direction of the running track where the driving end 20a and the moving mechanism 10 drive the driving portion 20 is in a vertical state or has a set angle of inclination Or the relative position between the moving mechanism 10 and the driving section 20 can be adjusted, and the angle between the plane or direction on which the moving track of the moving mechanism 10 drives the driving section 20 and the driving end 20a can be adjusted to be inclined or vertical. [0054] It can be understood that when the relative position between the movement mechanism 10 and the driving member 20 is fixed, the angular position relationship between the driving end 20a and the plane or direction on which the movement track of the movement mechanism 10 drives the driving portion 20 is fixed and cannot be fixed. It can also be understood that when the relative position between the moving mechanism 10 and the driving member 20 can be adjusted, the plane or direction and driving position of the running trajectory that can move the moving mechanism 10 to drive the driving portion 20 cannot be excluded during the adjustment process. The end 20a is adjusted in a parallel state.

[0055] Preferably, the plane or direction on which the driving end 20a and the running trajectory of the driving part 20 driven by the movement mechanism 10 are perpendicular to each other.

[0056] Preferably, the driving end 20a and the plane or direction on which the moving track of the driving mechanism 20 drives the driving section 20 are perpendicular to each other, and the sliding end of the main sliding part 70 and the plane on which the moving track of the driving mechanism 20 drives the driving section 20 are located. The directions are inclined to each other.

[0057] Preferably, the plane or direction on which the driving end 20a and the running track of the driving mechanism 20 drive the driving unit 20 are inclined with each other, and the sliding end of the main taxiing portion 70 and the plane on which the moving mechanism 10 drives the driving track 20 are located. The directions are perpendicular to each other.

[0058] The taxiing tool provided by the present invention, the taxiing of the main taxiing portion 70 relies on the driving force generated when the driving end 20a moves against the ice or snow, wherein the movement of the driving portion 20 having the driving end 20a is caused by The moving mechanism 10 drives; therefore, the angular position relationship between the driving end 20a and the sliding end of the main sliding part 70 and the plane or direction of the driving track 20 of the driving part 20 driven by the moving mechanism 10 and the driving end 20a and the main sliding The angular position relationship between the taxiing ends of the parts 70 is the main factor affecting the way of sliding of the main taxiing part 70; the relative position between the movement mechanism 10 of the taxiing tool and the main taxiing part 70 can be adjusted, so that during actual taxiing, the Change the angle between the plane or direction where the driving end 20a is driven by the movement mechanism 10 and the sliding end of the main sliding part 70 according to the need for taxiing, and / or, change the distance between the driving end 20a and the sliding end of the main sliding part 70 Angle, thereby changing the gliding mode, so that the gliding tool can better adapt to different working conditions and gliding needs.

[0059] For example, during the same motion cycle that the motion mechanism 10 moves, the driving end 20a moves to drive the main taxiing portion 70 according to the distance of the three (the driving end 20a, the sliding end of the main sliding portion 70, and the motion mechanism 10). The angle of the plane or direction on which the driving part 20 moves is different according to different angles, specifically as follows: During the same motion cycle of the motion mechanism 10, when the relative position between the motion mechanism 10 and the main sliding part 70 is adjusted to The angle between the plane or direction of the driving trajectory of the driving part 20 driven by the moving mechanism 10 and the sliding end of the main sliding part 70 is inclined or vertical. The driving end 20 a and the moving mechanism 10 drive the driving part 20 to move. When the planes or directions on which the running trajectories are located are perpendicular or inclined to each other, the smaller the angle between the driving end 20a and the sliding end of the main sliding part 70 or the more parallel (excluding parallel), the more the sliding distance of the main sliding part 70 long.

[0060] In a specific solution, by adjusting the relative position of the movement mechanism 10 and the main sliding portion 70, the driving end 20a of the driving portion 20 and the sliding end of the main sliding portion 70 can be placed in an inclined state, a vertical state, or a parallel state with each other. Alternatively, the inclination angle between the driving end 20a and the sliding end of the main sliding part 70 is changed.

[0061] Here, the driving coasting state refers to a state in which the motion mechanism 10 drives the driving unit 20 to further drive the main coasting unit 70 to coast. In contrast, when the motion mechanism 10 is not in motion, a coasting state exists.

[0062] In order to achieve the shifting effect, the driving end 20a of the driving portion 20 and the sliding end of the main taxiing portion 70 may be inclined to each other by adjusting. In the driving coasting state, the angle between the two determines the degree of shifting.

[0063] Of course, in practice, the driving end 20a of the driving portion 20 and the sliding end of the main taxiing portion 70 may be parallel to each other. In this state, it can be understood that the driving portion 20 cannot actually drive the main taxiing portion 70. The function of taxiing, however, the entire taxiing tool can rely on inertial taxiing. At this time, the taxiing resistance can be reduced. In addition, from this parallel state, there are two angle directions to choose from to adjust the driving end 20a of the driving section 20 and the main The angle between the taxiing ends of the taxiing portion 70 can play a role of switching the taxiing tool in the forward or reverse driving state (similar to the switching of the forward gear and the reverse gear of the vehicle); The reverse or forward effect of the glide tool.

[0064] In practice, the driving end 20a of the driving unit 20 and the plane or direction on which the driving locus of the driving unit 20 is driven by the movement mechanism 10 may be perpendicular to each other, and the plane on which the driving locus of the driving unit 20 is driven by the movement mechanism 10 is located. Or the directions are parallel to the taxiing ends of the main taxiing portion 70.

[0065] In a specific solution, the movement mechanism 10 may be rotatably connected to the main sliding part 70, and the positional relationship between the two may be adjusted by rotation. Of course, it can be understood that in addition to turning, in practice, other connection methods can also be selected to realize the position adjustment of the two.

[0066] Specifically, the movement mechanism 10 includes a frame 11, and the main sliding portion 70 includes a bracket 71. The frame 11 and the bracket 71 are rotatably connected through a first rotating shaft 95 to realize the rotation connection between the movement mechanism 10 and the main sliding portion 70.

[0067] Specifically, a support frame 94 is fixedly connected to the bracket 71. The first rotation shaft 95 passes through the corresponding mounting hole on the support frame 94 and the frame 11. Both the support frame 94 and the frame 11 are rotatably connected to the first rotation shaft 95.

[0068] In order to conveniently adjust the relative position between the movement mechanism 10 and the main sliding portion 70, the sliding tool may further be provided with a driving member 80 for driving the frame 11 to rotate relative to the bracket 71. [0069] In a specific solution, the driving member 80 includes a handle 81, a first driving wheel 82, a first driven wheel 83, and a belt tensioned on the first driving wheel 82 and the first driven wheel 83. Chain (not shown).

[0070] The handle 81 and the first driving wheel 82 can be fixed by a fixed shaft, and the fixed shaft is rotatably connected to the bracket 71 of the main sliding part 70. That is, when the handle 81 is rotated, the first driving wheel 82 can be driven The bracket 71 rotates relative to the bracket 71. The first driven wheel 83 is fixedly connected to the frame 11 connected to the moving mechanism 10, and the first driven wheel 83 is coaxially disposed with the first rotating shaft ₉₅ .

[0071] In this way, when the handle 81 is rotated, the first driving wheel 82 rotates synchronously, and the second driven wheel 83 is driven to rotate by a belt or a chain transmission, thereby driving the movement mechanism 10 to rotate about the first rotation shaft 95, thereby changing the movement mechanism 10 and the main shaft. The relative positional relationship between the taxiing portion 70 and the driving portion 20 connected to the movement mechanism 10 and the main sliding portion 70 changes the angle between the driving end 20a of the driving portion 20 and the sliding end of the main sliding portion 70, and The angle between the plane or direction on which the driving end 20 a is driven by the movement mechanism 10 and the sliding end of the main sliding part 70.

[0072] It should be noted that, in practice, the handle 81 is not provided, and it is also feasible to directly connect the first driving wheel 82 to the bracket 71, but relatively speaking, the operation is not provided with the handle 81.

[0073] In a specific solution, the driving device further includes a driving source and a transmission component, wherein the transmission component is connected between the driving source and the motion mechanism 10. Specifically, the transmission component includes a second driving wheel (not shown in the figure) connected to the driving source, a second driven wheel 98, a belt or a chain tensioned on the second driving wheel and the second driven wheel 98.

[0074] The transmission component further includes a gear assembly, as shown in FIG. 1 and FIG. 2. In this solution, the gear assembly includes an input gear 91, an intermediate gear 93, and an output gear 92; wherein the input gear 91 and the second gear The driven wheel 98 is fixedly connected, the output-side gear 92 is fixedly connected to the movement mechanism 10, and the input-side gear 91 and the output-side gear 92 are engaged with the intermediate gear 93.

[0075] During operation, the second driving wheel is driven to rotate by the driving source, and the second driven wheel 98 is driven to rotate by the belt or chain transmission. Since the input gear 91 is fixedly connected to the second driven wheel 98, the second driven wheel 98 rotates. The time synchronization drives the input gear 91 to rotate, and the input gear 91 drives the output gear 92 to rotate through the intermediate gear 93, thereby driving the movement mechanism 10 to move.

[0076] In this solution, the movement mechanism 10 is specifically in the form of a link structure, and each link of the movement mechanism 10 moves with each other, and finally drives the driving unit 20 to move.

[0077] As shown in the figure, specifically, the transmission component further includes a support frame 94, the first end of the support frame 94 and the main sliding portion The bracket 71 of 70 is fixedly connected, and the second end is rotatably connected to the frame 11 of the movement mechanism 10.

[0078] Specifically, the second end of the support frame 94 includes an upper ear plate 941 and a lower ear plate 942, and the positions of the two are corresponding to each other. A rotatable first is inserted between the upper ear plate 941 and the lower ear plate 942. The rotating shaft 95, that is, the first rotating shaft 95 can rotate relative to the support frame 94, wherein the intermediate gear 93 is sleeved on the first rotating shaft 95. In specific settings, the intermediate gear 93 can be relatively fixed to the first rotating shaft 95, or can be relatively The first rotating shaft 95 rotates.

[0079] A bending plate 943 is further provided between the upper ear plate 941 and the lower ear plate 942. The bending plate 943 is inserted with a rotatable second rotating shaft 96, one end of the second rotating shaft 96 and the second slave The moving wheel 98 is fixedly connected, and the other end is fixedly connected to the input-side gear 9 1.

[0080] Specifically, the frame 11 of the moving mechanism 10 is inserted with a rotatable third rotating shaft 97. One end of the third rotating shaft 97 is fixedly connected to the input link of the moving mechanism 10, and the other end is fixed to the output gear 92. Pick up.

[0081] Among them, the input-side gear 91, the output-side gear 92, and the intermediate gear 93 are all bevel gears, of course, they can also be other types of gears as long as power transmission can be achieved.

[0082] It can be understood that the foregoing is only a specific embodiment of the transmission component. In practice, the transmission component provided between the driving source and the movement mechanism 10 may have various forms. Based on the above specific embodiment, other components may be made. Transform.

[0083] In this solution, since there is only one intermediate gear 93, the input gear 91 and the output gear 92 are both meshed with the intermediate gear 93H. The input gear 91 and the output gear 92 are each meshed with the intermediate gear 93H. Limitation of the limit of movement of the movement mechanism 10 relative to the main sliding portion 70 constitutes a certain degree of limitation.

[0084] To avoid the above situation, improvements can be made to the above gear assembly. For details, please refer to FIG. 4 and FIG. 4, which are partial structural diagrams of a second embodiment of a taxiing tool provided by the present invention.

[0085] Compared with the foregoing embodiment, the difference of this embodiment is only that the gear assembly is improved, and other basic structures remain unchanged.

[0086] In this embodiment, the gear assembly includes an input gear 91, an output gear 92, and two intermediate gears 93a

, 93b.

[0087] As shown in the figure, two intermediate gears 93a, 93b are fixed on the first rotating shaft 95 up and down, wherein the input gear 91 meshes with the intermediate gear 93a, and the output gear 92 meshes with the intermediate gear 93b, because the two intermediate gears The gears 93 a and 93 b are fixed on the first rotating shaft 95. While the input gear 91 drives the intermediate gear 93 a to rotate, the intermediate gear 93 b and the first rotating shaft 95 also rotate together, thereby driving the output gear 92 to rotate, which in turn drives the exercise machine. Iko 10 moves.

[0088] In this way, the input gear 91 and the output gear 92 are meshed with different intermediate gears, respectively, without interference, and the motion mechanism 10 can rotate with respect to the main sliding part 70 to have a larger action range, so that the sliding tool is More adaptable.

[0089] In addition, the gear assembly of the transmission component of the driving device may further include only two parallel-set intermediate gears 93a, 93b fixed to the first rotating shaft 95, and one of the two intermediate gears 93a is connected to the drive source, The other is drivingly connected to the movement mechanism 10, that is, the driving source directly drives the intermediate gear 93a or 93b to move, and the second driving wheel, the second driven wheel 98, and the belt tensioned therebetween in the foregoing solution can be omitted. Or the chain, and the input gear 91; This arrangement can reduce the number of parts and components, and can make the structure of the driving device more compact.

[0090] It can be understood that, in actual setting, the transmission component of the driving device may only include the output gear 92 mentioned above. If the structural space and the actual situation allow, the driving source may be directly connected to the output gear 92 for transmission.

[0091] In the first embodiment shown in FIG. 1 described above, the movement mechanism 10 and the driving unit 20 are relatively fixed. In actual installation, the movement mechanism 10 and the driving unit 20 may also be configured to be relatively adjustable in position. In this way, the angle between the plane or direction on which the motion mechanism 10 drives the driving end 20a and the driving end 20a can also be adjusted, and / or the angle between the driving end 20a and the sliding end of the main sliding part 70 can be adjusted. angle.

[0092] That is, in order to adjust the angle between the plane or direction on which the motion mechanism 10 drives the driving end 20a and the sliding end of the main sliding part 70, and / or, adjust the driving end 20a and the main sliding part. The angle between the sliding ends of 70 can be adjusted to the relative position between the moving mechanism 10 and the main sliding part 70. The specific form is as described above, and the relative position between the moving mechanism 10 and the driving part 20 can also be set. The position can be adjusted, or the above-mentioned movement mechanism 10 and the main sliding part 70, and both the movement mechanism 10 and the driving part 20 can be adjusted in the angular position.

[0093] The embodiment in which the relative angular position between the moving mechanism 10 and the main sliding portion 70 is adjustable has been described in detail above, and the implementation manner in which the relative position between the moving mechanism 10 and the driving portion 20 is adjustable is described below.

[0094] Please refer to FIG. 18 and FIG. 19. In a specific solution, the driving portion 20 and the moving mechanism 10 are also rotationally connected, and the connecting post 21 of the driving portion 20 is inserted into the connecting pipe 103 of the moving mechanism 10. The relative position between the moving mechanism 10 and the driving part 20 is adjusted by rotating each other, and then the driving end 20a and the main sliding part 70 are adjusted. The angle between the sliding ends; the connection tube 103 and the connection column 21 can be used with a clearance fit, or other fixing methods. For example, a screw hole can be opened in the wall of the connection tube 103, and the connection tube 103 can be fixed by means of a top screw.和连接柱 21。 And connecting column 21.

[0095] In a specific solution, the driving portion 20 is a structure in which a roller is installed, a bottom end of the roller is a driving end 20a, and a rolling direction of the roller is a driving end direction or a driving end extension direction.

[0096] In order to achieve a speed-change effect, when the angle or plane between the plane or direction on which the motion mechanism 10 drives the driving end 20a and the gliding end of the main sliding part 70 is vertical or inclined, the motion mechanism 10 drives the driving end 20a to move. The angle between the plane or direction of the running track and the driving end 20a is vertical or inclined. By adjusting the angle between the driving end 20a of the driving part 20 and the sliding end of the main taxiing part 70, in the driving taxiing state, The angle between the two determines the speed of the shift.

[0097] When the coasting tool relies on inertia, if the angle between the driving end 20a and the coasting end of the main coasting portion 70 is adjusted to a parallel state, the coasting resistance can be reduced.

[0098] Please refer to FIG. 5. FIG. 5 is a schematic structural diagram of a first specific embodiment of a main sliding part of the sliding tool shown in FIG. 1.
