Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of ski machines, and particularly relates to an indoor intelligent ski machine. BACKGROUND

[0002] With the popularity of ice and snow sports, indoor ski machines have become an important carrier to break the geographical and climatic restrictions. However, the current indoor ski machines on the market have many limitations in structural design and function implementation, which are specifically as follows:

[0003] In terms of mechanical structure, most indoor ski machines adopt a single plane conveyor belt type design. Such ski machines are driven by a motor to operate a conveyor belt, the surface of the conveyor belt is covered with frosted material or simulated snow blanket, and the speed of the conveyor belt is adjusted to simulate the skiing sliding speed. However, this structure has inherent deficiencies. The flat conveyor belt can only provide straight sliding in a single direction, and cannot build three-dimensional terrain changes of real snow tracks. The terrain such as slopes, pits and curves in real snow tracks can allow skiers to experience complex actions such as center of gravity shift and side sliding turning. However, due to the structural limitations, the existing ski machines cannot simulate such scenes, so that skiers can only perform simple straight sliding, and it is difficult to achieve a sports experience comparable to real skiing. In addition, the adjustment mechanism of some ski machines with slope adjustment function is complex and bulky, and the adjustment process is slow. Not only a large amount of space is occupied, but also it is difficult to quickly respond to the needs of skiers for different slopes, further limiting the richness of skiing experience.

[0004] From the perspective of function implementation, the existing indoor ski machines have relatively single functions. The basic equipment can only meet the simple sliding training needs of skiers, and cannot provide diversified sports scenes. Even if some equipment is equipped with a slope adjustment device, the adjustment range is usually between 5-15°, and the adjustment is usually manual or slow, so that steep slopes or wavy snow tracks in high mountain skiing cannot be simulated. At the same time, the existing ski machines generally lack multi-functional integrated design, and cannot be compatible with different use scenes such as skiing teaching and entertainment competition. In addition, the lack of sports state monitoring and analysis function is also a shortcoming. The equipment cannot collect data such as skiing speed, posture angle and motion trajectory of skiers in real time by using sensors, and cannot evaluate and feedback the action standardization and motion consumption of skiers based on these data, so it is difficult to meet the individual training and entertainment needs of users, and greatly limits the improvement of professionalism and interest of indoor skiing sports.

Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0043] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0044] like Figure 1 , Figures 5 to 8 The diagram shown illustrates the structure of an indoor intelligent ski machine according to an embodiment of the present invention, comprising:

[0045] A support beam 800 is provided, the front end of which is connected to the front support electric cylinder assembly 900, and the rear end of which is connected to the rear support base 600, forming a total support frame. The total support frame is based on the lifting and adjusting slope of the front support electric cylinder assembly 900.

[0046] Motor 100 is installed on one side of the main support frame;

[0047] The front roller 200 is installed at the front end of the main support frame and is driven by the output end of the motor 100. A planar support mechanism 300 is provided on one side of the front roller 200.

[0048] The rear roller 500 is installed at the rear end of the main support frame. Tensioning mechanisms 700 are distributed at both ends of the rear roller 500, and another planar support mechanism 300 is provided on one side of the rear roller 500.

[0049] The composite adjustment mechanism 400 is installed on the main support frame and located between the front roller 200 and the rear roller 500;

[0050] The ski mat is mounted on the front roller 200 and the rear roller 500 and operates based on the motor 100, the front roller 200 and the rear roller 500.

[0051] In one embodiment of the present invention, the indoor intelligent ski machine addresses the problems mentioned in the background by providing a front support electric cylinder assembly 900, which is height-adjustable and thus adjusts the slope of the ski machine. By providing a composite adjustment mechanism 400, it can be used to simulate different terrain undulations. Before use, the front support electric cylinder assembly 900 and the composite adjustment mechanism 400 are set as needed to adjust the slope and switch terrain modes. The motor 100 is started, which drives the front roller 200 to rotate, thereby driving the ski mat to run at a set speed.

[0052] Among them, the supporting beam 800 can be made of large square steel with a length of 4500mm, a width of 80mm, a height of 120mm, and a thickness of 3mm, and the material is Q235 steel. It is spliced ​​with high-strength aluminum alloy profiles to form a rectangular frame, which can ensure the load-bearing capacity and effective sliding size.

[0053] Motor 100 can be equipped with an RX57Y2 helical gear reducer motor with a rated power of 1.5kW, a reduction ratio of 1:50, and a rated output speed of 300r / min. It can be driven by helical gear meshing with a transmission efficiency of 92%. Compared with spur gear transmission, the noise is reduced by 15dB (actual value), and the output torque is ≥200N・m, which can meet the high-speed operation requirements of ski mats.

[0054] like Figure 2 As shown, in a preferred embodiment of the present invention, the front support electric cylinder assembly 900 includes:

[0055] Base 901;

[0056] There are three electric cylinders 902, two of which are installed on both sides of the base 901, and one electric cylinder 902 is located on the lower side of the motor 100, and the motor 100 is supported by the motor base 904.

[0057] There are two connecting frames 903, which are installed on two electric cylinders 902 and connected to the supporting beam 800.

[0058] The front support electric cylinder assembly 900 is set at the front of the ski machine. Among them, the electric cylinder 902 can be model LN65-50-R500-ST90.80-750W. By setting three electric cylinders 902, the slope of the ski machine can be adjusted synchronously. The base 901 has a rectangular structure with dimensions of 3480mm (length) × 300mm (width) × 20mm (height). A rectangular weight reduction hole is opened in the middle, and the weight reduction ratio reaches 25%, which reduces the weight of the equipment while ensuring structural rigidity.

[0059] like Figure 3 As shown, in another preferred embodiment of the present invention, the tensioning mechanism 700 includes:

[0060] Fixed bracket 701 is installed on the main support frame;

[0061] The positioning slide 702 is connected to the rear roller 500 and is mounted on the fixed bracket 701 via a slide rail;

[0062] The screw 703 passes through the fixed bracket 701 from one side and contacts the positioning slide 702 to adjust the position of the positioning slide 702. The screw 703 is provided with a nut 704.

[0063] By rotating the screw 703, the positioning slide 702 can be moved between the slide rails, thereby achieving ski carpet tension. This maintains constant ski carpet tension (tension range 800~1200N) and prevents slippage. The screw 703 is locked by the nut 704.

[0064] like Figure 4 As shown, in a preferred embodiment of the present invention, the composite adjustment mechanism 400 includes:

[0065] The electric cylinder assembly 403 is provided in multiple sets and is connected to the main support frame through the upper connecting flange 404 and the lower connecting flange 405.

[0066] The roller bearing housing 402 is connected to the electric cylinder assembly 403, and the roller assembly 401 is installed on the roller bearing housing 402 to simulate terrain undulations.

[0067] The electric cylinder group 403 can be a device with model number 53-40-RX-ST60-400W, with a stroke of 300mm and a rated thrust of 5000N. The roller group 401 is evenly distributed along the length of the ski carpet (spacing ≈ 417mm). Electric cylinder groups 403 are set on both sides of the roller group 401 for driving. The coordinated lifting and lowering of one or both sides of the electric cylinder group 403 simulates the terrain undulation.

[0068] like Figure 8 As shown, in a preferred embodiment of the present invention, the ski machine further includes a fence installed on both sides and the top of the main support frame.

[0069] A fence has been installed to enhance safety.

[0070] like Figure 9 As shown in the preferred embodiment of the present invention, the ski machine further includes a fusion monitoring unit for real-time collection and analysis of skier motion data.

[0071] Specifically, the fusion monitoring unit includes:

[0072] Speed ​​sensors, distributed on both sides of the planar support mechanism 300, are used to collect sliding speed;

[0073] Attitude sensors, located along the edges of the ski mat, are used to collect body tilt angles.

[0074] Pressure sensors, distributed on the composite adjustment mechanism 400, are used to collect data on the center of gravity distribution.

[0075] This ski simulator can also collect skier's motion data in real time by setting up a fusion monitoring unit, providing motion standardization scores and optimization suggestions to improve training professionalism. Specifically, it includes a speed sensor (sampling frequency 100Hz, accuracy ±0.1km / h); an attitude sensor (gyroscope + accelerometer, sampling frequency 200Hz, angle measurement range ±90°, accuracy ±0.5°); and a pressure sensor (sampling frequency 50Hz, accuracy ±10N). The data is separated and analyzed using a data fusion processing module, and then feedback and training reports are output using a motion scoring system.

[0076] The working process of the ski machine is as follows: Figure 10 As shown, it includes the following steps:

[0077] Start the device and perform a system self-test;

[0078] When the user selects a terrain mode (such as slope, wave track, curve), the system calls the preset displacement parameters of electric cylinder group 403.

[0079] The electric cylinder group 403 works in coordination to complete the terrain switching within 3 seconds, while the motor 100 drives the ski carpet to run at a set speed (0~30km / h).

[0080] The integrated monitoring unit collects data in real time and dynamically adjusts terrain parameters (such as fine-tuning the slope based on the skier's center of gravity shift).

[0081] After the exercise ends, the system resets (the terrain returns to level, and the ski mat stops).

[0082] This ski machine, through the collaboration of a 3D terrain simulation support and an electric cylinder, can achieve continuous slope adjustment from 0 to 16° and the reproduction of wavy terrain. The ski carpet speed reaches 30 km / h, accurately simulating the real snow track environment and solving the problem of the single terrain simulation of existing equipment. It integrates a monitoring unit to collect skier's movement data in real time, providing action standardization scores and optimization suggestions to improve training professionalism. The structural design allows for an effective skiing size of 4000mm×2500mm and a load-bearing capacity of ≥500kg, meeting the needs of users of different body types. The modular quick-release structure facilitates ski carpet replacement, improving maintenance efficiency by 50%. Furthermore, the equipment has undergone finite element analysis to verify its strength, ensuring safe and reliable operation.

[0083] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
