Description

Technical Field

[0001] The present invention belongs to the field of sports equipment, and in particular relates to a multi-person cooperative sliding device. Background Art

[0002] In recent years, with the prevalence of skiing, skiing has gradually become a mainstream winter outdoor sport, such as the highly novel and entertaining multi-person cooperative skiing. Multi-person cooperative skiing equipment usually includes two skis. When multiple (e.g., two) users use the multi-person cooperative skiing equipment to ski, the users are divided into a leader and a follower, standing on two skis respectively. The user on each ski uses the same or similar control method as a regular single-ski device to control the skiing action of the ski. The follower, who has poor skiing skills, is driven by the action of the ski on the leader's side to follow the skiing. In this case, whether the movement states of the two skis on the leader's side and the follower's side are coordinated determines the overall movement balance of the multi-person cooperative skiing equipment.

[0003] Utility model patent application number 201720065753.X discloses a dynamically balanced multi-person cooperative gliding device. Specifically, the device comprises two skis, a linkage assembly connected between the two skis, and a synchronized stopper assembly. The synchronized stopper assembly, which is configured in the form of a rope, is connected to each of the two skis, allowing the two skis to swing synchronously relative to the linkage assembly. This allows the synchronized stopper assembly to better coordinate the direction and amplitude of movement of the two skis, each carrying a leader and a follower. A drawback of this device is that, because the synchronized stopper assembly is in the form of a rope, the rope's movement is susceptible to significant friction with other components of the device (such as the linkage assembly) during the process of coordinating the movement of the two skis. This friction causes the rope to wear to varying degrees after each use of the device, shortening the device's service life. Furthermore, when the skis are driven by the user, power is lost during transmission to the skis due to this friction, requiring greater driving force to operate the device. Accordingly, there is a need in the art for a new multi-person cooperative gliding device to address the aforementioned issues. Summary of the Invention

[0007] In the preferred technical solution of the above-mentioned multi-person cooperative sliding device, the limiting member is a clamp that is sleeved on the gear belt between the driving gear and the driven gear.

[0011] In the preferred technical solution of the above-mentioned multi-person cooperative sliding device, the first sliding assembly and the second sliding assembly each include a slide plate and a bracket provided on the slide plate, and the driven gear is fixed to the bracket.

[0012] In the preferred technical solution of the above-mentioned multi-person cooperative sliding device, the bracket includes a first rod segment provided on the slide and a second rod segment movably connected to the first rod segment, and the driven gear is fixed to the second rod segment.

[0013] In a preferred technical solution of the above-mentioned multi-person cooperative sliding device, the first rod segment is configured to be rotatable at least relative to the longitudinal axis of the second rod segment.

[0014] In a preferred technical solution of the above-mentioned multi-person cooperative sliding device, the multi-person cooperative sliding device further includes a control handle and a vertical connecting rod connected to the control handle, and the driving gear is fixed to the bottom end of the vertical connecting rod.

[0016] It will be understood by those skilled in the art that, in the preferred technical solution of the multi-person cooperative sliding device of the present invention, the multi-person cooperative sliding device includes a first sliding assembly, a second sliding assembly, and a synchronous transmission assembly.

[0031] See first Figure 1 and Figure 2 , Figure 1 is a schematic diagram of the overall structure of the first embodiment of the multi-person cooperative skiing equipment of the present invention, Figure 2 FIG. 1 is a schematic diagram of the forward structure of the first embodiment of the multi-person cooperative skiing device of the present invention. Figure 1 and Figure 2As shown, the multi-person cooperative skiing device of the present invention includes a main body 1 for carrying users to slide on the snow, a control handle 2, and a synchronous transmission assembly 4 arranged between the main body 1 and the control handle 2. The main body 1 includes a first sliding assembly 11 and a second sliding assembly 12 for carrying users. The synchronous transmission assembly 4 includes an active component, two driven components, and a transmission belt, one of which is fixedly connected to the first sliding assembly 11, and the other is fixed to the second sliding assembly 12. The active component is connected to the two driven components via the transmission belt, so that the active component can drive the two driven components to move synchronously through the transmission belt, thereby achieving synchronous movement of the first sliding assembly 11 and the second sliding assembly 12, and coordinating the sliding states of the first sliding assembly 11 and the second sliding assembly 12. The control handle 2 is connected to the active component via a vertical connecting rod 3, that is, the top end of the vertical connecting rod 3 is connected to the control handle 2, and the bottom end is fixedly connected to the active component, so that the user can control the movement of the active component by manipulating the control handle 2. When multiple (such as two) users stand on the first sliding component 11 and the second sliding component 12 respectively to ski, the users on both sides can hold on to the control handle 2 and manipulate the control handle 2 to transmit power to the first sliding component 11 and the second sliding component 12 through the transmission path of the vertical connecting rod 3-active component-driven component-first sliding component 11 / second sliding component 12, thereby controlling the sliding state of the first sliding component 11 and the second sliding component 12 by manipulating the control handle 2.

[0032] like Figure 2 As shown, the control handle 2 is exemplarily composed of a pair of U-shaped handle structures arranged opposite each other, wherein the two U-shaped handle structures respectively constitute a first grip portion 21 for the leader and a second grip portion 22 for the follower. The vertical connecting rod 3 comprises a first bracket 31 formed by a pair of generally E-shaped structures fixedly connected to each other, and a central rod 32 fixed to the first bracket 31. The ends of the middle and bottom crossbars of the two E-shaped structures, which extend laterally, are fixedly connected to the top and middle portions of the central rod 32 from the front and rear sides, respectively, to enhance the strength of the vertical connecting rod 3. The top crossbars of the two E-shaped structures, which extend laterally, are fixed to a set of opposing surfaces on the outer circumference of the control handle 2 to securely connect the control handle 2 to the vertical connecting rod 3. Of course, the vertical connecting rod 3 is not limited to the above structure. For example, if the vertical connecting rod 3 is sufficiently strong, it can also be a straight rod connected between the control handle 2 and the horizontal connecting rod 41.

[0033] See also Figure 3 、 Figure 4 And continue to read Figure 1 and Figure 2 , Figure 3is a partial structural diagram of a synchronous transmission assembly of a first embodiment of a multi-person cooperative skiing device of the present invention, Figure 4 FIG is a schematic diagram of the overall structure of the synchronous transmission assembly of the first embodiment of the multi-person cooperative skiing equipment of the present invention. Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, as a preferred embodiment, the synchronous transmission assembly 4 further includes a transverse connecting rod 41, the active member is a driving gear 42 pivotally connected to the middle portion of the transverse connecting rod 41 via a pivot connection (such as a pivot shaft), and the two driven members are driven gears 43 pivotally connected to the left and right ends of the transverse connecting rod 41 via pivot shafts, respectively. The transmission belt is a gear belt 44 having a plurality of tooth structures arranged on one side and meshing with the driving gear 42 and the two driven gears 43, respectively. The driving gear 42 is connected to the two driven gears 43 via the gear belt 44.

[0034] As an example, the first sliding assembly 11 and the second sliding assembly 12 each include a slide 13 for sliding on snow and a second bracket 15 for connecting the slide 13 and the driven gear 43. Each slide 13 is also provided with a pair of footrests 14. The bottom end of the second bracket 15 is fixed between the two footrests 14, and the top end is fixedly connected to the driven gear 43.

[0035] See also Figure 5 , Figure 5 Schematic diagram of the motion turning tilt state of the first embodiment of the multi-person cooperative skiing device of the present invention. Figure 5 As shown, when the leader and the following skater stand on the first and second slide assemblies 11 and 12, respectively, by stepping on the footrests 14, the two users support themselves on the first gripping portion 21 and the second gripping portion 22 of the control handle 2 from the left and right sides. The leader pushes the control handle 2 away from them or pulls it toward them, causing the vertical link 3 to swing left or right, causing the driving gear 42 to rotate counterclockwise or clockwise relative to the transverse link 41 as the vertical link 3 swings left and right. In this case, the gear belt 44 moves simultaneously in the clockwise or counterclockwise direction driven by the driving gear 42, so as to drive the two driven gears 43 to rotate simultaneously counterclockwise or clockwise, so that the second bracket 15 arranged between the first sliding component 11 / the second sliding component 12 and the driven gear 43 swings to the right or left at the same time, thereby causing the slides 13 of the first sliding component 11 and the second sliding component 12 to make a rightward or leftward tilted edge action at the same time, so as to realize various sliding states such as simultaneous left and right turning, deceleration and stopping of the first sliding component 11 and the second sliding component 12.

[0036] like Figure 2、 Figure 4 and Figure 5 As shown, due to the large overall load of the multi-person cooperative skiing device and multiple users, it is relatively laborious to rely solely on the user (mainly the leader) manually manipulating the control handle 2 and using their feet to change the tilt direction of the skateboard 13 to control the skiing state of the device. Therefore, the multi-person cooperative skiing device of the present invention can also be equipped with a drive component. The drive component is arranged at the position of the driving gear 42 or the driven gear 43 to drive the driving gear 42 or the driven gear 43 to rotate clockwise or counterclockwise according to the user's control intention, thereby providing power to drive the multi-person cooperative skiing device to slide. As an example, the drive component is a drive motor 47 connected to the driven gear 43.

[0037] Continue reading Figure 3 and Figure 4 To enhance the assembly reliability of the driving gear 42 and the driven gear 43 with the gear belt 44 and prevent the gear belt 44 from partially or completely falling off the driving gear 42 or the driven gear 43, the synchronous transmission assembly 4 preferably further includes a limiting member. This limiting member increases the meshing area between the driving gear 42 and / or the driven gear 43 and the gear belt 44 by constraining the gear belt. Specifically, the limiting member is a cylindrical clamp 45 adapted to the dimensions (such as width and thickness) of the gear belt 44. After the middle portion of the gear belt 44 engages with the upper and lower sides of the driving gear 42, the left and right sides of the gear belt 44 respectively pass through the clamp 45 and then engage with the driven gear 43. This reduces the spacing between the upper and lower bands of the gear belt 44 on either side of the driving gear 42, increases the number of meshing teeth between the upper and lower bands and the upper and lower sides of the driving gear 42, and ensures accurate and reliable power transmission while effectively enhancing the assembly reliability between the gear belt 44 and the driving gear 42.

[0038] like Figure 3 and Figure 4As shown, as a preferred embodiment, the driven gear 43 is pivotally connected to the transverse connecting rod 41 with one side thereof proximate to the transverse connecting rod 41, and is fixedly connected to the second bracket 15 on the other side. Specifically, the driven gear 43 is disposed between the transverse connecting rod 41 and the second bracket 15. The second bracket 15 includes a first rod segment 151 and a second rod segment 152 movably connected to the first rod segment 151. Specifically, the top end of the second rod segment 152 is fixedly connected to the driven gear 43. The first rod segment 151 is a Y-shaped rod, the bifurcated end of which is fixed to the skateboard 13. When the second bracket 15 and the skateboard 13 are fixed, they form a triangular support structure, ensuring a secure connection between the second bracket 15 and the skateboard 13. The other end of the Y-shaped rod is movably connected to the bottom end of the second rod segment 152, such that the first rod segment 151 can rotate at least relative to the longitudinal axis of the second rod segment 152. This allows the movement of the left and right skateboards 13 to remain substantially consistent, while improving the mobility of the multi-person cooperative skiing device. For example, the top end of the first rod segment 151 is pivotally connected to the second rod segment 152 via a spherical joint.

[0039] In this case, as an example, a U-shaped through groove recessed downward is further provided at the top of the second rod segment 152, so that the ends of the driven gear 43 and the cross-link 41 can be connected to the second rod segment 152 by being embedded in the U-shaped through groove. That is, in the assembled state, one side arm of the U-shaped through groove is fixed to one side of the driven gear 43, and the end of the cross-link 41 is pivotally connected to the other side of the driven gear 43, so that at least a portion of the ends of the driven gear 43 and the cross-link 41 (such as the lower half of the lower driven gear 43) are located in the U-shaped through groove, so that the lower meshing position of the gear belt 44 and the driven gear 43 is accommodated in the groove, further improving the assembly reliability of the driven gear 43 and the gear belt 44.

[0040] like Figure 3As shown, to prevent the first and second slide assemblies 11 and 12 from tilting at excessive angles, making it difficult for users to maintain balance in the multi-person skiing device, a preferred embodiment provides blocking members 46 at both driven gears 43. Specifically, blocking members 46 comprise a sector-shaped base plate 461 and cylindrical extensions 462 extending radially outward from the curved surface of base plate 461. Two extensions 462 extend radially from the upper and lower sides of the curved surface of base plate 461, respectively, in the radial direction of the driven gear 43. Limiting posts 411 extend outwardly from both ends of the cross-link 41, proximate to the driven gear 43. In the assembled state, base plate 461 is secured to the side of the second bracket 15 away from the driven gear 43, such that the two extensions 462 extend obliquely along the upper and lower sides of the driven gear 43, with each limiting post 411 positioned between the two extensions 462 of each base plate 461. When the driven gear 43 is driven by the gear belt 44 and rotates to a certain angle in the clockwise direction or counterclockwise direction, the extended end 462 on the upper side or the lower side of the driven gear 43 abuts against the limit post 411 under the drive of the driven gear 43 (the abutting state can be seen). Figure 6 ), thereby preventing the slide 13 from swinging too far by preventing the driven gear 43 from continuing to rotate. Furthermore, the position and extension angle of each extension end 462 on the base plate 461 can be customized based on actual usage requirements to adjust the range of the tilt angles of the first slide assembly 11 and the second slide assembly 12, thereby meeting the safety and protection requirements of users of varying levels of experience.

[0041] It will be understood by those skilled in the art that the structure of the limiting member and the blocking member 46 is not limited to the structural form of the clamp 45, the base plate 461, and the protruding end 462. As long as the limiting member can ensure the meshing reliability between the gear belt 44 and the gears (the driving gear 42 and the driven gear 43), and the blocking member 46 can meet the requirement of preventing the driven gear 43 from continuing to rotate, it will be sufficient. For example, the limiting structure can also be a pair of relatively arranged L-shaped blocks, and the parts of the gear belt 44 located on the upper and lower sides of the driving gear 42 are respectively clamped in the blocks. Furthermore, the structure of the second bracket 15 is not restrictive. For example, in order to facilitate the user to control the skateboard 13 with his feet, the flexibility of the skateboard 13 relative to the driven gear 43 does not need to be too high. In this case, the second bracket 15 can also be a whole connecting rod arranged between the driven gear 43 and the skateboard 13 without a movable connection structure. Changes in the specific structural forms of the above-mentioned components do not exceed the principles and protection scope of the present invention.

[0042] See also Figure 6 and Figure 7 , Figure 62 is a schematic diagram of the overall structure of the synchronous transmission assembly of the second embodiment of the multi-person cooperative skiing equipment of the present invention. Figure 7 It is a partial structural diagram of the synchronous transmission assembly of the second embodiment of the multi-person cooperative skiing equipment of the present invention. As another preferred embodiment, the active component is the active pulley 5 pivotally connected to the middle part of the transverse connecting rod 41. The driven component is the driven pulley 6, which includes a first driven pulley 61 and a second driven pulley 62, and the first driven pulley 61 and the second driven pulley 62 are pivotally connected to the left and right ends of the transverse connecting rod 41 in sequence. The transmission belt is a belt 7 connecting the active pulley 5 and the driven pulley 6, and the belt 7 includes a first belt 71 and a second belt 72. Two belt grooves are provided on the active belt 6, and the first belt 71 and the second belt 72 are respectively embedded in the two belt grooves, so that the active pulley 5 can be connected to the first driven pulley 61 through the first belt 71, and can be connected to the second driven pulley 62 through the second belt 72. And according to Figure 6 In terms of orientation, the first belt 71 is fixed to the middle right side of the driving pulley 5 and the middle left side of the first driven pulley 61, respectively, and the second belt 72 is fixed to the middle left side of the driving pulley 5 and the middle right side of the second driven pulley 62, respectively. That is to say, fixed points are provided between the first belt 71, the second belt 72 and the driving pulley 5 and the first driven pulley 61 and the second driven pulley 62, so that the way of transmitting power between the belts and the pulleys is changed from friction transmission between the driving pulley 5, the (first and second) belts and the (first and second) driven pulleys to rotational transmission by the driving pulley 5 pulling the (first and second) driven pulleys through the (first and second) belts.

[0043] Of course, the position of the fixed points of the belt on each pulley is not limited. Without affecting the rotation angle of the first driven pulley 61 and the second driven pulley 62, the position of each fixed point can also be changed according to actual transmission requirements, such as changing it to the vicinity of the above-mentioned fixed points.

[0044] See also Figure 8 And continue to read Figure 7 , Figure 8 yes Figure 7 A partial enlarged view showing the fixing point between the first belt and the driving pulley of the synchronous transmission assembly. Figure 7 and Figure 8As shown, the specific method of fixing the belt 7 to the driving pulley 5 and the driven pulley 6 is as follows: the synchronous transmission assembly 4 also includes a pressure plate 8, the overall shape of the pressure plate 8 is roughly rectangular, and a protruding structure 81 is provided on one side surface of the pressure plate 8. When the pressure plate 8 abuts against the driving pulley 5 or the driven pulley 6, the protruding structure 81 is embedded in the belt groove of the (driving or driven) pulley and tightly abuts against the belt 7. Through holes are provided on the pressure plate 8 and the belt 7, and threaded holes are provided on the pulley. Screws 9 pass through the pressure plate 8 and the belt 7 in sequence and are screwed to the pulleys to ensure a fixed connection between the belt 7 and the pulleys.

[0045] When the leader pushes the control handle 2 away from or pulls it toward him, the vertical link 3 swings leftward or rightward, driving the driving pulley 5 fixed to its lower end to rotate counterclockwise or clockwise. Taking the counterclockwise rotation of the driving pulley 5 as an example, in this case, the lower portion of the first belt 71 fixedly connected to the driving pulley 5 (i.e., the portion of the first belt 71 located below the driving pulley 5 and the driven pulley 6) is pulled rightward, while the upper portion of the second belt 72 fixedly connected to the driving pulley 5 (i.e., the portion of the second belt 72 located above the driving pulley 5 and the driven pulley 6) is pulled leftward, causing the first and second driven gears 61, 62 to rotate simultaneously counterclockwise, driven by the first and second belts 71, 72. This in turn drives the first and second sliding assemblies 11, 12 fixedly connected to the first and second driven pulleys 61, 62 to simultaneously perform a leftward tilting edge-up motion.

[0046] Regarding the above, it should be noted that although the active component and the driven component are described in combination with gears and pulleys, this is not limiting. The active component and the driven component can also be other disc hub parts besides gears and pulleys, such as sprockets.

[0047] In summary, the multi-person cooperative sliding device of the present invention includes a first sliding assembly 11, a second sliding assembly 12, a control handle 2, and a synchronous transmission assembly 4. The synchronous transmission assembly 4 includes a horizontal connecting rod 41, a driving gear 42 disposed in the middle of the horizontal connecting rod 41, and two driven gears 43 disposed at each end of the horizontal connecting rod 41. The driving gear 42 is meshed with the two driven gears 43 via a gear belt 44. The control handle 2 is fixedly connected to the driving gear 42 via a vertical connecting rod 3. When the leader and the follower are respectively on the first sliding assembly 11 and the second sliding assembly 12 and each supports one side of the control handle 2, the leader can push or pull the control handle 2 to swing the vertical connecting rod 3 left or right, thereby causing the driving gear 42 to rotate clockwise or counterclockwise, and the gear belt 44 simultaneously transmits the rotational force of the driving gear 42 to the two driven gears 43 positions, so that the two driven gears 43 can rotate clockwise / counterclockwise, driving the slides 13 of the first sliding assembly 11 and the second sliding assembly 12 to tilt in the same direction at the same angle, thereby changing the sliding state of the multi-person cooperative skiing device and ensuring the movement coordination of the first sliding assembly 11 and the second sliding assembly 12, while ensuring that the power transmission process will not be affected by the large friction between the parts of the multi-person cooperative skiing device, greatly reducing the wear of the parts of the device (especially the transmission parts) and ensuring the service life of the device.
