Description

Technical Field

[0001] This invention belongs to the field of ski equipment technology, specifically an intelligent indoor ski machine that can simulate the slope changes of a real ski resort. Background Technology

[0002] With the call for "300 million people to participate in winter sports," the atmosphere surrounding winter sports continues to heat up. During the off-season, more and more professional skiers and beginners are practicing on indoor ski machines, making skiing less restricted by geographical location and climate. However, existing indoor ski machines mainly adjust the slope angle by adjusting the height of the hydraulic tilt bracket and regulate the speed of the ski mat through a motor system. This fails to simulate the unevenness and undulating slopes of a real ski run, resulting in a poor sense of immersion and a lack of a realistic skiing experience. Furthermore, the skiing modes are relatively limited.

[0003] Therefore, inventing a device that can adjust the slope of a ski mat to simulate a more realistic ski resort environment is of great significance. Summary of the Invention

[0004] This invention provides an intelligent indoor ski machine that can simulate the slope changes of a real ski resort. Its main purpose is to be able to respond quickly to continuous changes in slope, simulate a more realistic ski resort environment, enhance the user's skiing experience, and help skiers better master skiing techniques and advance their skiing skills.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows:

[0006] A smart indoor ski machine that can simulate the slope changes of a real ski resort includes a ski machine steel frame 100, a left slope changing mechanism 200, a right slope changing mechanism 400, a rear roller 800, a ski mat motor 900, a front roller 1000, and a ski mat 1100.

[0007] The left slope changing mechanism 200 and the right slope changing mechanism 400 are located on the inner upper side of the ski machine steel frame 100. They have identical structures and are arranged facing each other. Both slope changing mechanisms consist of a slope changing mechanism motor 201, a coupling 202, a small pulley 203, a slider 204, a guide rail 205, a bevel gear 206, a lead screw 207, a push rod 208, a bearing seat 209, a top rod 210, a profile 211, a connecting rod 212, and a lead screw nut 213. The profile 211 is fixed to the ski machine steel frame 100, forming two rectangular bases; one end of the coupling 202 is connected to the variable slope mechanism motor 201, and the other end is connected to the transmission shaft connected to the small pulley 203 and the bevel gear 206. The small pulley 203 is located between the coupling 202 and the bevel gear 206. The variable slope mechanism motor 201 drives the small pulley 203 and the bevel gear 206 through the coupling, and the bevel gear 206 drives the... The lead screw 207 is fixed in the middle of the profile 211 via the bearing seat 209 and passes through the center of the push rod 208. The lead screw nut 213 is fixedly connected to the push rod 208, and the push rod 208 moves back and forth through the lead screw nut 213. The guide rails 205 are fixed on the left and right profiles 211 respectively. A slider 204 is set above the guide rails 205, which can slide along the guide rails 205. The sliders 204 are fixed on the lower sides of the push rod 208, so the push rod 208 can slide along the guide rails 205 on both sides. One end of the connecting rod 212 is hinged to the upper sides of the push rod 208 via a ball joint, and the other end is hinged to the top rod 210. The reciprocating motion of the push rod 208 will drive the connecting rod 212, which can raise or lower the top rod 210. When the top rod 210 is raised to different heights, the ski mat 1100 will also arch upwards, achieving the effect of locally changing the slope of the ski mat 1100 to create an up-and-down undulating effect.

[0008] The ski mat motor 900 is fixed to the right side of the ski machine steel frame 100. It drives the rear roller 800 to rotate through belt drive and coupling. The rear roller 800 then drives the power to the front roller 1000 through the ski mat 1100.

[0009] Preferably, an auxiliary support mechanism 300 is provided between the left slope changing mechanism 200 and the right slope changing mechanism 400, and the auxiliary support mechanism 300 is fixed on the ski machine steel frame 100; the auxiliary support mechanism 300 mainly consists of an electromagnetic clutch 301, a camshaft 302, a support rod 303, a stroke retainer 304, a large pulley 305, and an auxiliary support mechanism bearing seat 307;

[0010] The auxiliary support mechanism bearing seat 307 is fixedly installed on the ski machine steel frame 100. The large pulley 305 is located inside the auxiliary support mechanism bearing seat 307. The electromagnetic clutch 301 is located inside the large pulley 305. The transmission shaft of the auxiliary support mechanism is connected from the outside to the inside to one end of the auxiliary support mechanism bearing seat 307, the large pulley 305 and the electromagnetic clutch 301. The small pulley 203 drives the large pulley 305 through belt drive. The other end of the electromagnetic clutch 301 is engaged with the camshaft 302.

[0011] The support rod 303 is positioned above and in contact with the camshaft 302. The retainer 304 is fixed to the ski machine steel frame 100. The two ends of the support rod 303 are restricted in the stroke retainer 304. Due to the different radii of curvature of the camshaft 302, the support rod 303 will move up and down linearly under the restriction of the stroke retainer 304 during rotation. The support rod 303 plays an auxiliary support role and fits against the lower side of the ski mat 1100.

[0012] A further preferred embodiment includes a protrusion 306 on the outer contour of the large pulley 305. The limit switch 600 is fixed to the ski machine frame 100 and positioned on the outer edge of the contour of the large pulley 305. The protrusion 306 presses against the limit switch 600, causing the limit switch 600 to be in a closed state. When the large pulley 305 rotates, the protrusion 306 moves away from the limit switch 600, and the limit switch 600 is in an open state. The limit switch 600 controls the on / off state of the electromagnetic clutch 301 through a circuit. When the limit switch 600 is open, the electromagnetic clutch 301 is engaged, and the large pulley 305 drives the camshaft 302 to rotate through the electromagnetic clutch 301.

[0013] Preferably, the present invention can achieve the following by setting the transmission ratio of the large and small pulleys: when the two variable slope mechanisms lift the top rod 210, the support rod 303 in the auxiliary support mechanism 300 will also rise in height according to the set ratio.

[0014] Preferably, a right tensioning mechanism 500 and a left tensioning mechanism 700 are provided on the lower inner side of the ski machine steel frame 100; the left tensioning mechanism 700 includes small spring rods 701 and small rollers 702, with the two small spring rods 701 sleeved at both ends of the small rollers 702; the right tensioning mechanism 500 includes large spring rods 501 and large rollers 502, with the two large spring rods 501 sleeved at both ends of the large rollers 502; both the large rollers 502 and the small rollers 702 are in contact with the ski mat 1100, and both the small spring rods 701 and the large spring rods 501 are in a tensioned state.

[0015] Preferably, a tilt adjustment mechanism is provided below the ski machine frame 100. This mechanism consists of a telescopic rod motor 1300, a telescopic rod 1400, and a drive shaft 1500. The telescopic rod motor 1300 is located on the lower outer side of the ski machine frame 100 and is connected to the drive shaft 1500 via belt drive. Telescopic rods 1400 are fixed at both ends of the drive shaft 1500. One end of the telescopic rod 1400 is connected to the drive shaft 1500, and the other end is connected to the ski machine frame 100 via a hinge. The rotation of the telescopic rod motor 1300 drives the drive shaft 1500, which can change the extension length of the telescopic rod 1400. The left side of the ski machine frame 100 is hinged and fixed to the ground, changing the angle between the ski machine frame 100 and the horizontal plane, thereby adjusting the tilt angle of the overall structure.

[0016] Preferably, a handrail 1200 is installed on the front side of the ski machine steel frame 100, and guardrails are also provided on the left, right and rear sides.

[0017] The advantages of this invention compared to existing technologies are as follows:

[0018] 1. Most indoor ski machines currently only change the tilt angle of the overall structure, while the structural device of this invention can not only change the tilt angle of the overall structure, but also quickly change the slope of the ski mat in a localized area to achieve an up-and-down undulating effect, thereby enhancing the skier's experience.

[0019] 2. The device of the present invention can be set to multiple skiing modes to meet the requirements of skiers at different stages such as beginners and advanced skiers, making it more intelligent. Attached Figure Description

[0028] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0030] like Figure 1-7 The intelligent indoor ski machine shown can simulate the slope changes of a real ski resort, including a ski machine steel frame 100, a left slope changing mechanism 200, a right slope changing mechanism 400, a right tensioning mechanism 500, a left tensioning mechanism 700, a rear roller 800, a ski mat motor 900, a front roller 1000, and a ski mat 1100.

[0031] The left slope adjustment mechanism 200 and the right slope adjustment mechanism 400 are located on the upper inner side of the ski machine steel frame 100. They have the same structure and are arranged facing each other.

[0032] Both variable slope mechanisms consist of a variable slope mechanism motor 201, a coupling 202, a small pulley 203, a slider 204, a guide rail 205, a bevel gear 206, a lead screw 207, a push rod 208, a bearing seat 209, a top rod 210, a profile 211, a connecting rod 212, and a lead screw nut 213;

[0033] The profile 211 is fixed to the ski machine steel frame 100, forming two rectangular bases. One end of the coupling 202 is connected to the variable slope mechanism motor 201, and the other end is connected to the transmission shaft connected to the small pulley 203 and the bevel gear 206. The small pulley 203 is located between the coupling 202 and the bevel gear 206. The variable slope mechanism motor 201 drives the small pulley 203 and the bevel gear 206 through the coupling. The bevel gear 206 drives the lead screw 207 through the bevel gear transmission. The lead screw 207 is fixed in the middle of the profile 211 through the bearing seat 209, and passes through the center of the push rod 208. The lead screw nut 213 is fixedly connected to the push rod 208, and the push rod 208 moves back and forth through the lead screw nut 213. Guide rails 205 are fixed to the left and right profiles 211 respectively. A slider 204 is provided above the guide rails 205, which can slide along the guide rails 205. The sliders 204 are fixed to the lower sides of the push rod 208, so the push rod 208 can slide along the guide rails 205 on both sides. One end of the connecting rod 212 is hinged to the upper sides of the push rod 208 via a ball joint, and the other end is hinged to the top rod 210. The reciprocating motion of the push rod 208 will drive the connecting rod 212, which can raise or lower the top rod 210. When the top rod 210 is raised to different heights, the ski carpet will also arch upwards, achieving the effect of locally changing the slope of the ski carpet and creating an undulating effect.

[0034] The auxiliary support mechanism 300 is located between the left slope changing mechanism 200 and the right slope changing mechanism 400 and is fixed on the ski machine steel frame 100. The auxiliary support mechanism 300 consists of an electromagnetic clutch 301, a camshaft 302, a support rod 303, a stroke retainer 304, a large pulley 305, a protrusion 306 and an auxiliary support mechanism bearing seat 307.

[0035] The auxiliary support mechanism bearing housing 307 is fixedly mounted on the ski machine steel frame 100. A large pulley 305 is located inside the auxiliary support mechanism bearing housing 307, and an electromagnetic clutch 301 is located inside the large pulley 305. The drive shaft of the auxiliary support mechanism connects, from the outside in, one end of the auxiliary support mechanism bearing housing 307, the large pulley 305, and one end of the electromagnetic clutch 301. A small pulley 203 drives the large pulley 305 via belt drive. The other end of the electromagnetic clutch 301 engages with a camshaft 302. A protrusion 306 is located on the outer contour of the large pulley 305. A limit switch 600 is fixed to the ski machine steel frame 100 and located on the outer edge of the large pulley 305's contour. The protrusion 306 presses against the limit switch 600, keeping the limit switch in a closed state. When the large pulley 305 rotates, the protrusion 306 moves away from the limit switch 600, opening the limit switch. The limit switch 600 controls the on / off state of the electromagnetic clutch 301 via a circuit. When the limit switch 600 is disconnected, the electromagnetic clutch 301 is engaged, and the large pulley 305 drives the camshaft 302 to rotate via the electromagnetic clutch 301. The support rod 303 is positioned above and in contact with the camshaft 302, and the retainer 304 is fixed to the ski machine frame 100. Both ends of the support rod 303 are confined within the travel retainer 304. Due to the different radii of curvature of the camshaft 302, during rotation, the support rod 303 will move linearly up and down under the constraint of the travel retainer 304. The support rod 303 provides auxiliary support and rests against the underside of the ski mat 1100.

[0036] While the two slope-changing mechanisms raise the top rod 210, the support rod 303 in the auxiliary support mechanism 300 will also rise to a proportional height. This proportional relationship can be achieved by setting the transmission ratio of the large and small pulleys, so as to realize the linkage between the top rod 210 in the slope-changing mechanism and the support rod 303 in the auxiliary support mechanism 300.

[0037] The right-side tensioning mechanism 500 and the left-side tensioning mechanism 700 are located on the inner side below the ski machine frame 100. The left-side tensioning mechanism 700 includes small spring rods 701 and small rollers 702, with the two small spring rods 701 fitted onto both ends of the small rollers 702. The right-side tensioning mechanism 500 includes large spring rods 501 and large rollers 502, with the two large spring rods 501 fitted onto both ends of the large rollers 502. Both the large rollers 502 and the small rollers 702 are in contact with the ski mat 1100, and both the small spring rods 701 and the large spring rods 501 are in a tensioned state. During the up-and-down movement of the ski mat 1100, the length of the ski mat 1100 above the ski machine frame 100 will increase, causing the large spring rods 701 and the small spring rods 501 to be further compressed. The length of the ski mat 1100 below the ski machine frame 100 will shorten, providing redundancy for the ski mat 1100.

[0038] A tilt adjustment mechanism is provided below the ski machine frame 100. This mechanism consists of a telescopic rod motor 1300, a telescopic rod 1400, and a drive shaft 1500. The telescopic rod motor 1300 is located on the lower outer side of the ski machine frame 100 and is connected to the drive shaft 1500 via belt drive. The telescopic rod 1400 is fixed at both ends of the drive shaft 1500. One end of the telescopic rod 1400 is connected to the drive shaft 1500, and the other end is connected to the ski machine frame 100 via a hinge. The rotation of the telescopic rod motor 1300 drives the drive shaft 1500, which can change the extension length of the telescopic rod 1400. The left side of the ski machine frame 100 is hinged and fixed to the ground. By changing the angle between the ski machine frame 100 and the horizontal plane, the tilt angle of the overall structure can be adjusted.

[0039] The ski mat motor 900 is fixed to the right side of the ski machine steel frame 100. It drives the rear roller 800 to rotate through belt drive and coupling. The rear roller 800 drives the power to the front roller 1000 through the ski belt 1100.

[0040] A handrail 1200 is installed on the front of the ski machine's steel frame 100, and guardrails are also provided on the left, right and rear sides for safety protection.

[0041] One specific application of this embodiment is that, during use, when the user is skiing indoors, after putting on skis and other skiing equipment, they set the corresponding skiing mode. These modes include beginner mode, slope mode, and mountain skiing mode. In beginner mode: the ski mat motor 900 starts, driving the ski mat 1100 to move diagonally upwards. The speed of the ski mat motor 900 is controlled within a stable range, and the speed increases slowly over time. In slope mode: the ski mat motor 900 starts, driving the ski mat 1100 to move diagonally upwards. The user skis in the middle area of ​​the ski mat 1100. The indoor ski machine simulates the user skiing on a slope that first increases and then decreases. The slope is changed by adjusting the telescopic rod motor 1300. The rotation of the telescopic rod motor 1300 can adjust the extension of the telescopic rod 1400 to a certain length, thus changing the tilt angle of the entire ski machine. The telescopic rod 1400 extends first, and after running for a period of time, the motor is adjusted to allow the extension... The telescopic bar shortens to achieve an effect where the slope first increases and then decreases. It also allows adjustment of the ski mat motor to change the ski mat's speed, altering the user's gliding speed. In mountain skiing mode: the user prepares to ski in the area between the two slope-changing mechanisms 200 and 400; the telescopic bar motor 1300 starts, and the telescopic bar 1400 extends to a certain length, at which point the entire ski machine has a tilt angle; after skiing for a period of time, the left slope-changing mechanism motor 201 starts, the push rod 210 rises a certain distance, the limit switch 600 disengages, the electromagnetic clutch 301 engages, and the push rod 303 also rises a certain distance, compressing the right tensioning mechanism 500 and the left tensioning mechanism 700, reducing the slope of the ski mat 1100; similarly, when the right slope-changing mechanism 400 starts, the slope of the ski mat 1100 increases. As time progresses, the frequency of the two slope-changing mechanisms appropriately increases, creating a continuously changing slope on the ski mat 1100.

[0042] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. It can be applied to various fields suitable for the present invention. Other modifications can be readily made by those skilled in the art. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and examples shown and described herein.
