Description

Technical Field

[0001] This invention relates to the field of exercise bike technology, and more specifically, to a balance correction device for exercise equipment. Background Technology

[0002] Exercise bikes, also known as spin bikes, are a popular aerobic exercise equipment in both home and commercial settings. They simulate the outdoor cycling experience, allowing users to control exercise intensity by adjusting magnetic or wind resistance. The seat and handlebars are multi-adjustable to accommodate people of different heights, providing a comfortable and stable riding posture.

[0003] Currently, existing exercise bikes typically only monitor exercise data and cannot identify hidden center of gravity shifts during static sitting postures or dynamic cycling. Long-term use of incorrect postures can easily lead to lumbar muscle strain or scoliosis.

[0004] Therefore, in view of this, we have studied and improved the existing structure to provide a balance correction device for fitness equipment, in order to achieve a more practical purpose. Summary of the Invention

[0005] 1. Technical problems to be solved

[0006] In view of the problems existing in the prior art, the purpose of this invention is to provide a balance correction device for fitness equipment, which can realize the "visualization" and "active intervention" of the body's center of gravity balance during fitness, identify the hidden center of gravity shift in static sitting posture or dynamic cycling, avoid incorrect fitness posture, and significantly improve the safety and scientificity of rehabilitation training and physical exercise.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A balance correction device for fitness equipment, comprising:

[0010] Exercise bike frame: Exercise bike frame is equipped with exercise wheels at both the front and rear. A seat support tube is vertically fixed to the top rear of the exercise bike frame. The upper end of the seat support tube is flexibly fitted with the seat body. The bottom of the seat body is equipped with a guide limit frame. The guide limit frame is U-shaped and its two ends are fixed to the bottom sides of the seat body. The middle part of the guide limit frame is fitted around the outer periphery of the seat support tube.

[0011] Force-bearing seats: including a left force-bearing seat and a right force-bearing seat arranged symmetrically on the left and right sides. Both the left and right force-bearing seats are installed on the side of the exercise wheel at the rear via a crank handle. The left foot pedal is installed on the upper surface of the left force-bearing seat, and the right foot pedal is installed on the upper surface of the right force-bearing seat.

[0012] Balance sensing assembly: includes a left pressure strain gauge group and a right pressure strain gauge group, wherein the left pressure strain gauge group is embedded on the left side of the upper surface of the seat body, and the right pressure strain gauge group is embedded on the right side of the upper surface of the seat body.

[0013] Furthermore, both the left and right force-bearing seats are rectangular aluminum alloy blocks, and both have multiple anti-slip grooves on their upper surfaces, which are arranged parallel to each other in the left-right direction.

[0014] Furthermore, the crank handle end on the side of the exercise wheel is provided with a mounting groove, and the left force seat and the right force seat are respectively embedded in the corresponding mounting groove, and the depth of the mounting groove is greater than the thickness of the left force seat or the right force seat.

[0015] Furthermore, the left pressure strain gauge group includes three strain gauges evenly distributed along the left side of the upper surface of the seat body, and the right pressure strain gauge group includes three strain gauges evenly distributed along the right side of the upper surface of the seat body.

[0016] Furthermore, both sides of the guide limit frame are provided with elongated adjustment holes, and the side wall of the seat support tube is provided with multiple threaded holes. The fastening bolts pass through the adjustment holes and are screwed into the threaded holes.

[0017] Furthermore, both the left and right foot pedals are made of rubber, and their lower surfaces are provided with multiple positioning protrusions.

[0018] The upper surfaces of the left and right force-bearing seats are respectively provided with positioning holes, and the positioning protrusions are inserted into the positioning holes, and the positioning protrusions and positioning holes are magnetically attracted to each other.

[0019] Furthermore, a locking sleeve is fitted onto the top of the seat support tube, and the inner wall of the locking sleeve is threadedly connected to the outer wall of the seat body. Rotating the locking sleeve drives the seat body to move up and down axially along the seat support tube.

[0020] Furthermore, a counterweight base is fixedly connected to the bottom of the exercise bike frame, and the counterweight base is in the shape of a trapezoidal block.

[0021] 3. Beneficial Effects

[0022] Compared with the prior art, the advantages of this invention are:

[0023] This solution enables "visualization" and "active intervention" of the body's center of gravity balance during fitness activities, identifies hidden center of gravity shifts in static sitting postures or dynamic cycling, avoids incorrect fitness postures, and significantly improves the safety and scientific nature of rehabilitation training and physical exercise.

[0024] By directly installing symmetrical pressure strain gauges on the seat, minute changes in the center of gravity are captured from the mechanical source. Combined with the pressure signals received from the foot pedals by the two force-bearing seats, the data is fed back to the exercise bike's built-in display screen in real time. The data can also be transmitted to the corresponding APP. The exercise bike's corresponding system analyzes and processes the data, guiding users to actively correct poor posture. This not only effectively prevents sports injuries but also specifically trains the stability of the core muscle groups. Attached Figure Description

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0039] Example:

[0040] Please see Figure 1 - Figure 4 A balance correction device for fitness equipment, comprising:

[0041] Exercise bike frame 1: Exercise bike frame 1 is equipped with exercise wheels at both the front and rear. A seat support tube 101 is vertically fixed to the top rear of exercise bike frame 1. The upper end of the seat support tube 101 is flexibly fitted with a seat body 102. A guide limit frame 2 is provided at the bottom of the seat body 102. The guide limit frame 2 is U-shaped, and its two ends are fixed to the bottom sides of the seat body 102 respectively. The middle part of the guide limit frame 2 is fitted around the outer periphery of the seat support tube 101 to limit the horizontal displacement of the seat body 102.

[0042] Force-bearing seats: including left force-bearing seat 3 and right force-bearing seat 4 arranged symmetrically on the left and right sides. Both left force-bearing seat 3 and right force-bearing seat 4 are installed on the side of the exercise wheel at the rear via a crank handle. The upper surface of left force-bearing seat 3 is equipped with a left foot pedal 301, and the upper surface of right force-bearing seat 4 is equipped with a right foot pedal 401.

[0043] Balance sensing component 5: includes a left pressure strain gauge group 501 and a right pressure strain gauge group 502. The left pressure strain gauge group 501 is embedded on the left side of the upper surface of the seat body 102, and the right pressure strain gauge group 502 is embedded on the right side of the upper surface of the seat body 102. The left pressure strain gauge group 501 and the right pressure strain gauge group 502 are configured to collect the force data on the left and right sides and feed it back to the user through an external display terminal.

[0044] By using the left force-bearing seat 3, the left pressure strain gauge group 501, the right force-bearing seat 4, and the right pressure strain gauge group 502 arranged symmetrically on the left and right sides, the pressure distribution of the user's left and right buttocks and legs under sitting posture is directly collected, and the body's center of gravity shift is identified from the mechanical root.

[0045] The guide limiter 2, in conjunction with the height-adjustable seat, ensures the stability of the seat installation and adapts to the needs of users of different heights, providing accurate basic mechanical data support for posture correction.

[0046] Specifically, both the left support seat 3 and the right support seat 4 are rectangular aluminum alloy blocks, and both have multiple anti-slip grooves 302 on their upper surfaces, which are arranged parallel to each other in the left and right directions.

[0047] Rectangular aluminum alloy blocks are high in strength and lightweight, and can stably transmit pressure.

[0048] The anti-slip groove 302 increases the friction between the foot pedal and the bearing seat, preventing relative slippage during use and improving the accuracy of data collection.

[0049] Specifically, the crank handle end on the side of the exercise wheel has a mounting groove 104, and the left force seat 3 and the right force seat 4 are respectively embedded in the corresponding mounting groove 104. The depth of the mounting groove 104 is greater than the thickness of the left force seat 3 or the right force seat 4, forming a cavity for accommodating the balance sensing component 5.

[0050] Mounting slot 104 enables the embedded fixing of the left force-bearing seat 3 and the right force-bearing seat 4, resulting in a compact and aesthetically pleasing structure;

[0051] The reserved accommodating cavity provides independent installation space for the left pressure strain gauge group 501 and the right pressure strain gauge group 502, avoiding damage from external compression while ensuring the directness of force transmission.

[0052] Specifically, the left pressure strain gauge group 501 includes three strain gauges evenly distributed along the left side of the upper surface of the seat body 102, and the right pressure strain gauge group 502 includes three strain gauges evenly distributed along the right side of the upper surface of the seat body 102.

[0053] The multi-point distributed strain gauges can collect pressure data at different locations on the seat body 102, effectively distinguishing the pressure difference between the buttocks and thighs, improving the spatial resolution of the force data, and making the balance analysis more precise.

[0054] Specifically, both sides of the guide limit frame 2 are provided with elongated adjustment holes 201, and the side wall of the seat support tube 101 is provided with multiple threaded holes 1011. The fastening bolts pass through the adjustment holes 201 and are screwed into the threaded holes 1011 to achieve height locking of the guide limit frame 2.

[0055] The elongated adjustment hole 201, in conjunction with the multi-position threaded hole 1011, enables flexible adjustment of the guide limit frame height 2, allowing it to be synchronized with the lifting stroke of the seat body 102, thus ensuring the lateral stability of the seat at different heights.

[0056] Specifically, both the left foot pedal 301 and the right foot pedal 401 are made of rubber, and the lower surface is provided with multiple positioning protrusions 3011;

[0057] The upper surfaces of the left force-bearing seat 3 and the right force-bearing seat 4 are respectively provided with positioning holes 303. The positioning protrusion 3011 is inserted into the positioning hole 303, and the positioning protrusion 3011 and the positioning hole 303 are magnetically attracted to each other.

[0058] The rubber foot pedal has good cushioning and anti-slip properties, improving user comfort; the insertion and engagement of the positioning protrusion 3011 and the positioning hole 303 enables quick disassembly and precise positioning of the foot pedal, facilitating later maintenance and replacement.

[0059] Specifically, a locking sleeve 1012 is fitted onto the top of the seat support tube 101. The inner wall of the locking sleeve 1012 is threadedly connected to the outer wall of the seat body 102. Rotating the locking sleeve 1012 drives the seat body 102 to move up and down axially along the seat support tube 101.

[0060] The threaded locking sleeve 1012 has a simple and reliable structure. The seat height can be continuously adjusted by rotation. It is easy to operate and has good self-locking performance, which can prevent the seat from sliding down unexpectedly during use.

[0061] Specifically, a counterweight base 103 is fixed to the bottom of the exercise bike frame 1, and the counterweight base 103 is in the shape of a trapezoidal block.

[0062] The trapezoidal counterweight base 103 lowers the center of gravity of the entire machine, enhances the overall stability of the exercise bike, avoids the risk of the equipment tipping over due to the user's center of gravity shifting, and ensures safe use.

[0063] Working principle:

[0064] When the fitness equipment is in operation with the balance correction device, the user sits on the seat body 102 and steps on the left foot pedal 301 and the right foot pedal 401 with both feet respectively.

[0065] At this time, the left and right pressure strain gauge groups 501 and 502, distributed on the left and right sides of the upper surface of the seat, collect pressure signals from the buttocks and thighs in real time. Because the strain gauges are distributed in a multi-point configuration, they can accurately sense the pressure difference and specific distribution area between the left and right sides. The collected mechanical data is processed and transmitted to an external display terminal for intuitive feedback to the user. Simultaneously, the left and right force-bearing seats 3 and 4 can also detect the force signals of the corresponding footrests. If the user's center of gravity shifts due to improper posture, a significant deviation in the left and right pressure data will occur, and the display terminal will immediately indicate an imbalance.

[0066] Throughout the entire operation of the device, the guide limiter 2 remains fitted around the outer periphery of the seat support tube 101 during seat lifting and lowering, strictly limiting the horizontal swaying of the seat body 102 and ensuring that the mechanical data originates from the user's own posture changes rather than device displacement. Based on real-time feedback, the user actively adjusts their sitting posture or pedaling method until the left and right pressure data tend to be balanced, thereby achieving dynamic balance correction.

[0067] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
