Description

Technical Field

[0001] This manual relates to the field of fitness equipment, and in particular to a training mode switching device and switching method for fitness equipment. Background Technology

[0002] While fitness equipment meets people's needs for improved health and fitness, it is also constantly evolving and innovating. Fitness equipment primarily focused on strength training mainly uses a rotating motor system for power. Aerobic and strength training are achieved by adjusting the motor speed, but this cannot replicate the inertial feel of traditional aerobic training. Fitness equipment primarily focused on aerobic training (such as rowing machines and ski machines) primarily uses a linear rebound mechanism in its aerobic mode, with the power system continuously generating inertia. However, users often switch between strength and aerobic training modes simultaneously, making it impossible to achieve two different specialized training modes within a single machine.

[0003] Therefore, it is desirable to provide a training mode switching device for fitness equipment that can realize two different professional training modes in one piece of equipment. Summary of the Invention

[0030] A training mode switching device (hereinafter referred to as the switching device) for fitness equipment can switch states. In some embodiments, such as Figures 1a-1c As shown, the switching device includes a switching mechanism 100, a first connecting mechanism 200, and a second connecting mechanism 300 (see [reference]). Figure 4The switching mechanism 100 is used to switch the training mode of the fitness equipment by switching states. The switching mechanism 100 is operatively connected to either the first connecting mechanism 200 or the second connecting mechanism 300. In some embodiments, the first connecting mechanism 200 is connected to the switching mechanism 100 such that the fitness equipment is connected to the resistance module 500 (see...). Figure 6 The transmission connection is established, and the switching device is in the first state; the second connection mechanism 300 is connected to the switching mechanism 100 so that the fitness equipment and the resistance module 500 are connected by transmission, and the switching device is in the second state.

[0031] In some embodiments, the switching mechanism 100 is operably connected to the first connecting mechanism 200 or the second connecting mechanism 300 by manually moving the switching mechanism 100 to achieve this connection. In some embodiments, the switching mechanism 100 is operably connected to the first connecting mechanism 200 or the second connecting mechanism 300 by driving the switching mechanism 100 to achieve this connection via an electric device. The transmission connection can include various feasible forms, such as gear meshing transmission, linkage transmission, etc. Further details regarding transmission connections can be found in the description below.

[0032] Fitness equipment includes equipment for strength training and equipment for aerobic training. A resistance module 500 provides training resistance and may include a motor, power supply, and other devices. In some embodiments, the first state of the switching device corresponds to the strength training mode of the fitness equipment, where the resistance module 500 provides high resistance, requiring the user to resist greater resistance during exercise, resulting in high training intensity. The second state of the switching device corresponds to the aerobic training mode of the fitness equipment, where the resistance module 500 provides low resistance, requiring the user to resist less resistance during exercise, resulting in low training intensity. As described herein, high resistance means resistance greater than a first threshold; low resistance means resistance less than a second threshold. For the same fitness equipment, the first threshold is greater than or equal to the second threshold. For different fitness equipment, the first threshold and the second threshold may be different or the same. In some embodiments, for the same fitness equipment, the first threshold and / or the second threshold can be set according to user needs.

[0033] The first connecting mechanism 200 and / or the second connecting mechanism 300 may include a worm gear, a gear set, etc. In some embodiments, the first connecting mechanism 200 and the second connecting mechanism 300 may be different transmission mechanisms. In some embodiments, the first connecting mechanism 200 and the second connecting mechanism 300 may be the same transmission mechanism. In some embodiments, the first connecting mechanism 200 and the second connecting mechanism 300 may be transmission mechanisms with different output parameters. For example, the first connecting mechanism 200 and the second connecting mechanism 300 may be transmission mechanisms with different output torques and / or speeds. Further, for example, the first connecting mechanism 200 and the second connecting mechanism 300 may be worm gears with different transmission ratios and output torques. Further, for example, the first connecting mechanism 200 and the second connecting mechanism 300 may be gear sets with different transmission ratios and output torques. Yet another example is that the first connecting mechanism 200 is a worm gear and the second connecting mechanism 300 is a gear set. Different training modes can be achieved through different structural configurations of the first connecting mechanism 200 and the second connecting mechanism 300. More information about training modes can be found in the description below.

[0034] Figure 3a This is an exemplary structural diagram of a toggle assembly shown according to some embodiments of this specification. Figure 3b This is another exemplary structural diagram of the toggle assembly shown in some embodiments of this specification. Figure 3c This is an exemplary exploded view of the toggle assembly shown in some embodiments of this specification.

[0035] In some embodiments, such as Figures 3a-3c As shown, the switching mechanism 100 includes at least one toggle assembly 101. The at least one toggle assembly 101 includes a bracket 110 and a toggle member 120 slidably disposed on the bracket 110. The toggle member 120 is pulsatingly connected to the first connecting mechanism 200 or the second connecting mechanism 300 via the bracket 110. For details on the specific arrangement of the toggle member 120, please refer to the description below.

[0036] In some embodiments, the switching mechanism 100 may include two sets of symmetrically arranged toggle components 101, for example, such as Figures 1a-1c As shown, the switching mechanism 100 may include a first toggle assembly 101-1 and a second toggle assembly 101-2. The switching device may include a set of first connecting mechanisms and a set of second connecting mechanisms that are drivenly connected to the first toggle assembly 101-1, and another set of first connecting mechanisms and another set of second connecting mechanisms that are drivenly connected to the second toggle assembly 101-2.

[0037] In some embodiments, such as Figures 3a-3cAs shown, the bracket 110 may include a positioning shaft, which is fixedly mounted on the bracket 110. The positioning shaft may include a rod-like structure. The rod-like structure may be cylindrical, cuboid, or similar in shape. In some embodiments, the positioning shaft includes a first positioning shaft 111 and a second positioning shaft 112, which are spaced apart in the x-axis direction and in the y-axis direction. As described herein, "spaced apart in the x-axis direction" means that the first positioning shaft 111 and the second positioning shaft 112 are perpendicular to the x-axis; "spaced apart in the y-axis direction" means that the first positioning shaft 111 and the second positioning shaft 112 are perpendicular to the y-axis. In some embodiments, the first positioning shaft 111 and the second positioning shaft 112 are perpendicular to the plane formed by the x and y axes. The spacing between the first positioning shaft 111 and the second positioning shaft 112 in the x-axis and y-axis directions can be set as needed.

[0038] In some embodiments, the first positioning axis 111 includes a pair of first sub-positioning axes coaxially arranged in the z-axis direction, and the second positioning axis 112 includes a pair of second sub-positioning axes coaxially arranged in the z-axis direction. As described herein, coaxial arrangement in the z-axis direction means that the first positioning axis 111 and the second positioning axis 112 are arranged parallel to the z-axis.

[0039] In some embodiments, such as Figures 3a-3c As shown, the bracket 110 includes a first crossbar 110-1 and a second crossbar 110-2 arranged parallel to the x-axis, and the first crossbar 110-1 and the second crossbar 110-2 are spaced apart in the z-axis direction. Two first sub-positioning shafts of the first positioning shaft 111 can be respectively disposed on the lower surface of the first crossbar 110-1 and the upper surface of the second crossbar 110-2, and the two first sub-positioning shafts are coaxial in the z-axis direction. Two second sub-positioning shafts of the second positioning shaft 112 can be respectively disposed on the side surfaces of the first crossbar 110-1 and the second crossbar 110-2 (e.g., ...). Figures 3a-3c The middle side faces outward from the paper, and the two second sub-positioning axes are coaxial in the z-axis direction.

[0040] In some embodiments, the actuating member 120 may be slidably connected to the first positioning shaft 111 and the second positioning shaft 112. In some embodiments, when the actuating member 120 slides along at least one of the first positioning shaft 111 and the second positioning shaft 112, the actuating member 120 moves simultaneously in both the x-axis direction and the y-axis direction.

[0041] In some embodiments, the actuating member 120 includes a movable sleeve 121 and a connecting member. The movable sleeve 121 enables the actuating member 120 to move relative to the positioning shaft, and the connecting member enables the actuating member 120 to connect to the first connecting mechanism 200 or the second connecting mechanism 300. In some embodiments, the actuating member 120 may only include the movable sleeve 121, which has the connecting function of the connecting member, that is, while the actuating member 120 moves relative to the positioning shaft, the movable sleeve 121 also enables the actuating member 120 to connect to the first connecting mechanism 200 or the second connecting mechanism 300. In some embodiments, the movable sleeve 121 is provided with a Z-shaped groove 122, in which the first positioning shaft 111 and the second positioning shaft 112 are slidably disposed, and the Z-shaped groove 122 has a guiding function relative to the first positioning shaft 111 and the second positioning shaft 112. For example, the first positioning shaft 111 and the second positioning shaft 112 are respectively provided with protrusions that match the Z-shaped groove 122, and can be embedded in the Z-shaped groove 122. When the movable sleeve 121 moves, the protrusions move relative to the Z-shaped groove 122 within the Z-shaped groove 122. In some embodiments, the Z-shaped groove 122 can be any other feasible shape, as long as the two ends of the groove are spaced apart in the y-axis direction. For example, the Z-shaped groove 122 can be oblique. As another example, the Z-shaped groove 122 may include a straight line segment and an oblique line segment parallel to the x-axis direction.

[0042] For example, the Z-groove 122 may include a first straight segment, a diagonal segment, and a second straight segment. The first and second straight segments are parallel to the x-axis and are spaced apart in the y-axis direction (i.e., the first and second straight segments are at different positions in the y-axis direction). The diagonal segment connects the first and second straight segments. When the actuator 120 is moved in the x-direction, the Z-groove 122 slides relative to at least one of the first and second positioning shafts 111 and 112. When the first straight segment of the Z-groove 122 slides to the second straight segment (or the second straight segment slides to the first straight segment), the actuator 120 simultaneously moves in the y-axis direction under the action of the relatively fixed positioning shaft in conjunction with the Z-groove 122.

[0043] In some embodiments, such as Figure 3a As shown, when the actuating member 120 moves to the point where both the first positioning shaft 111 and the second positioning shaft 112 are located in the Z-shaped groove 122, the connecting member can be connected to the first connecting mechanism 200 in a transmission manner, and the switching device is in the first state.

[0044] In some embodiments, such as Figure 3b As shown, when the actuating member 120 moves to the point where only the second positioning shaft 112 is located in the Z-groove 122, the connecting member can be connected to the second connecting mechanism 300 in a transmission manner, and the switching device is in the second state.

[0045] In some embodiments, the connection between the connector and the first connecting mechanism 200 or the second connecting mechanism 300 can be a connection in the y-axis direction, that is, power transmission is realized in the y-axis direction. For example, such as Figures 1a-1c As shown, the connecting member can achieve a gear-meshing connection with the first connecting mechanism 200 or the second connecting mechanism 300 in the y-axis direction, thereby enabling power transmission. Further explanation of the transmission connection between the connecting member and the first connecting mechanism 200 or the second connecting mechanism 300 is provided below. When moving the actuating member 120, only a force in the x-axis direction needs to be applied to the actuating member 120 to achieve power transmission in the y-axis direction. Therefore, the direction of state switching (x-axis direction) of moving the actuating member 120 is different from the direction of transmission connection (y-axis direction), ensuring that they do not interfere with each other, resulting in a more stable connection and better power transmission effect.

[0046] In some embodiments, the switching mechanism 100 may include a plurality of toggle components 101, and the toggle members 120 of the plurality of toggle components 101 may move synchronously. For example, as Figure 1b The actuating element 120 of the first actuating assembly 101-1 and the actuating element 120 of the second actuating assembly 101-2 shown can be connected by a connecting rod 125, thereby ensuring that the two actuating elements 120 move synchronously and increasing the stability of the entire device.

[0047] In some embodiments of this specification, the toggle mechanism is designed to move simultaneously in both the x-axis and y-axis directions. By converting the user's operation on the toggle mechanism in the x-axis direction into movement of the toggle mechanism in the y-axis direction, the switching device can switch between two states with stable transmission.

[0048] In some embodiments, the bracket 110 may include a guide structure, such as a guide groove, and the actuating member may be provided with a guide element that matches the guide structure, such as an embedded protrusion, and the embedded protrusion of the actuating member 120 may move along the guide groove.

[0049] In some embodiments, the switching device may include a positioning structure, which may be a positioning post. The positioning post can extend in the moving direction of the toggle member 120 when the toggle member 120 moves to a set position (for example, when the toggle member 120 is connected to the first connecting mechanism 200 or the second connecting mechanism 300 in a transmission connection), thereby blocking the movement of the toggle member 120 and limiting the toggle member 120 so that the toggle member 120 is stably connected to the first connecting mechanism 200 or the second connecting mechanism 300 in a transmission connection.

[0050] In some embodiments, the positioning post may be connected to a micro motor, which can control the extension and retraction of the positioning post. In some embodiments, the actuating member 120 may include two independent parts, one part of which is movable to be driven to the first connecting mechanism 200, and the other part of which is movable to be driven to the second connecting mechanism 300. By controlling the movement of the two parts respectively, the switching mechanism 100 can be driven to the first connecting mechanism 200 or the second connecting mechanism 300.

[0051] In some embodiments, the switching mechanism 100 may also have any other feasible structure, as long as it can be operably connected to the first connecting mechanism 200 or the second connecting mechanism 300.

[0052] Figure 4 This is based on some embodiments shown in this specification. Figure 1c An exemplary partial structural diagram. Figure 5 This is an exemplary structural diagram of the central gear assembly shown in some embodiments of this specification.

[0053] In some embodiments, such as Figures 1a to 5 As shown, the first connecting mechanism 200 includes a central gear assembly 210 and a bevel gear 220, and the central gear assembly 210 includes a fixed gear 211. When the actuating member 120 slides to the first position, it drives the bevel gear 220 through the connecting member until the bevel gear 220 meshes with the fixed gear 211, and the switching device is in the first state.

[0054] In some embodiments, such as Figure 5 As shown, the central gear assembly 210 also includes a central locating pin 212. The fitness equipment may include a pulley assembly 460 and a drive shaft 470. The central gear assembly 210 is fixed to the drive shaft 470 by the central locating pin 212, and the rotation axis of the fixed gear 211 is perpendicular to the axis (y-axis direction) of the drive shaft 470. The drive shaft 470 is used to connect to the resistance module 500 to provide resistance to the fitness equipment.

[0055] In some embodiments, such as Figure 4 As shown, a bevel gear 220 is disposed on the side of the actuating member 120 near the pulley assembly 460, and the bevel gear 220 is connected to the pulley assembly 460. When the actuating member 120 moves along the negative y-axis, the connecting member of the actuating member 120 can drive the bevel gear 220 to move together along the negative y-axis. In some embodiments, the connecting member of the actuating member 120 can be any feasible structure, or the actuating member 120 may not have a connecting member, as long as the actuating member 120 can drive the bevel gear 220 to move along the negative y-axis.

[0056] In some embodiments, such as Figure 3a and Figure 4As shown, the first position refers to the maximum position of the toggle member 120 in the negative direction of the y-axis. At this time, the first positioning shaft 111 and the second positioning shaft 112 are both located in the Z-shaped groove 122, the bevel gear 220 meshes with the fixed gear 211, and the switching device is in the first state.

[0057] For example, such as Figure 2 As shown, the fitness equipment includes a pull rope 440 and an elastic band 350. The user trains by pulling the pull rope 440. When the user pulls the pull rope 440 and the elastic band 450, it drives the pull wheel assembly 460 to rotate. The rotation of the pull wheel assembly 460 drives the central gear assembly 210 to rotate. The resistance module 500 provides resistance (i.e., a force opposite to the force applied by the user) to the central gear assembly 210 through the drive shaft 470. When the user releases the force applied to the pull rope 440, the resistance module 500 also provides resistance to the drive shaft 470 and the pull wheel assembly 460. The pulled-out pull rope 440 rewraps around the pull wheel assembly 460, and the elastic band 450 returns to its original position along with the pull wheel assembly 460. Because the bevel gear 220 meshes with the central gear assembly 210, torque can be transmitted in both forward and reverse directions. The pull rope is subjected to the resistance provided by the resistance module 500 during both pulling out and retracting, and the fitness equipment is in a high-resistance, high-intensity strength training mode (i.e., mode one).

[0058] In some embodiments, such as Figure 4 As shown, the second connecting mechanism 300 includes a one-way wheel assembly 310, which includes a one-way gear 311. In some embodiments, when the actuating member 120 slides to the second position, it drives the connecting member to mesh with the one-way gear 311, and the switching device is in the second state. The pull wheel assembly 460 is connected to the one-way wheel assembly 310. In some embodiments, the one-way gear 311 meshes unidirectionally with the drive shaft 470. When the drive shaft 470 rotates forward, the one-way wheel assembly 310 rotates accordingly. When the drive shaft 470 rotates in reverse, the one-way gear 311 no longer meshes with the drive shaft 470, and the one-way gear 311 can rotate freely without transmitting torque. In some embodiments, the one-way wheel assembly 310 can be a gear assembly with one-way teeth on its end face.

[0059] In some embodiments, such as Figure 3b and Figure 4As shown, the second position refers to the maximum position of the actuating member 120 in the positive y-axis direction. At this time, only the second positioning shaft 112 is located in the Z-groove 122, and the one-way gear 311 meshes with the connecting member. In some embodiments, the connecting member may include internal teeth 123. The actuating member 120 moves along the positive y-axis direction, driving the internal teeth 123 to move together in the positive y-axis direction until the internal teeth 123 mesh with the one-way gear 311. At this time, the central gear assembly 210 and the bevel gear 220 are in a separated state. When the user pulls the pull rope 440 and the elastic rope 450, it drives the pull wheel assembly 460 to rotate. The rotation of the pull wheel assembly 460 drives the one-way wheel group 310 to rotate. The one-way wheel group 310 transmits torque, and the user is subjected to resistance provided by the resistance module 500 while pulling out the pull rope 440. When the user releases the force applied to the pull rope 440, the rebound force of the elastic rope 350 will cause the pull wheel assembly 460 to reverse, rewinding the pulled rope 440 back onto the pull wheel assembly 460. Since the one-way wheel assembly 310 does not transmit force or torque when reversed, the resistance module 500 provides no resistance. In this situation, the pull rope 440 experiences resistance when pulled out and has no resistance when retracted, and the fitness equipment is in a low-resistance, low-intensity aerobic training mode (i.e., mode two).

[0060] In some embodiments of this specification, the toggle assembly can switch between two connection methods: connecting the pull wheel assembly to the center gear assembly and connecting the pull wheel assembly to the unidirectional wheel set. This allows the fitness equipment to switch between strength training mode and aerobic training mode via the switching device, enabling users to easily obtain training modes using a single piece of equipment.

[0061] Figure 6 These are exemplary structural diagrams of fitness equipment shown in some embodiments of this specification.

[0062] Some embodiments of this specification also provide a fitness device, which includes a training mode switching device according to any embodiment of this specification. When the switching device is in a first state, the fitness device is in a first mode; when the switching device is in a second state, the fitness device is in a second mode. For example, as shown... Figure 6 As shown, the fitness equipment is a strength training station. The first mode corresponds to strength training, and the second mode corresponds to aerobic training. For details regarding the switching device status and the fitness equipment modes, please refer to the previous explanation; it will not be repeated here.

[0063] In some embodiments, such as Figure 6 As shown, the fitness equipment also includes a resistance module 500 and a pulley assembly 460 (see...). Figure 4In the first state, the switching device is drivenly connected to the resistance module 500 and the pulley assembly 460 via the first connecting mechanism 200; in the second state, the resistance module 500 and the pulley assembly 460 are drivenly connected via the second connecting mechanism 300. In some embodiments, the resistance module 500 includes an output shaft, which can be connected to the drive shaft 470 (see...). Figure 4 The resistance module 500 is connected to the pulley assembly 460 to transmit resistance to the fitness equipment. For details regarding the transmission connection between the resistance module 500 and the pulley assembly 460, please refer to the previous explanation; it will not be repeated here.

[0064] In some embodiments, such as Figure 2 As shown, the fitness equipment also includes a first housing 420, a second housing 430, a pull rope 440, and an elastic band 450. The first housing 420 and the second housing 430 are used to mount the fitness equipment components. The bracket 110 of the actuation assembly 101 can be mounted in the first housing 420 via a mounting member 410. The actuation assembly 101 can be connected to an operating member, which is movably disposed outside the first housing 420 for convenient user operation. For details regarding the pull rope 440 and the elastic band 450, please refer to the preceding description; they will not be repeated here.

[0065] In some embodiments, the fitness equipment further includes a physiological monitoring device, a motion monitoring device, and a controller. The controller is configured to control mode switching of the fitness equipment by controlling the state switching of a switching device.

[0066] A physiological monitoring device is a device used to monitor a user's physiological data (such as heart rate, blood pressure, blood oxygen, etc.). Physiological monitoring devices can be installed at points where the user comes into contact with the fitness equipment. A motion monitoring device is a device used to acquire a user's motion data (such as pulling force, speed, repetitions, etc.). For example, a motion monitoring device may include displacement sensors, speed sensors, and tension sensors mounted on a resistance band or elastic cord to monitor the movement and tension of the resistance band. These sensors can determine a complete resistance band movement by measuring the speed, displacement, or tension changes of the resistance band, thereby calculating the number of pulls.

[0067] In some embodiments, the switching device may further include a drive motor, which may be connected to the switching mechanism 100, for example, to the toggle member 120, so as to control the state switching of the switching device.

[0068] Some embodiments of this specification also provide a method for switching training modes of fitness equipment. The switching method includes: extracting the user's movement characteristics based on movement data acquired by a motion monitoring device; determining the user's movement state based on physiological monitoring data and movement characteristics acquired by a physiological monitoring device; and determining whether to switch the training mode of the fitness equipment based on the movement state.

[0069] In some embodiments, motion data may include a sequence of pulling force / velocity during training. Motion characteristics include a sequence consisting of the frequency of the target behavior per unit time, the duration of the target behavior, and the stability of the target behavior. The target behavior refers to a pre-set target exercise behavior, which is related to the type of fitness equipment. For example, if the fitness equipment uses ropes to complete different postures or movements, the target behavior is pulling the rope, regardless of the specific action of pulling the rope. The controller can extract the number of cycles of pulling force / velocity changes per unit time based on the pulling force / velocity sequence during training, and determine the number of cycles as the frequency of the target behavior per unit time. For example, the frequency of the target behavior per unit time could be the number of times the rope is pulled per minute. The duration of the target behavior refers to the time it takes for the user to complete the previous complete target behavior. The duration of the target behavior can be obtained by querying historical records. The stability of the target behavior is used to characterize the stability of the user's strength or speed during training. The stability of the target behavior can be obtained through statistical analysis. For example, the stability of the pulling force of the target behavior can refer to the standard deviation of multiple pulling force values ​​when completing the target behavior.

[0070] In some embodiments, a user's motion state can be represented by the degree of motion. In some embodiments, the more tired the user is, the lower the value of the degree of motion. In some embodiments, the controller can determine the degree of motion. The controller can compare physiological monitoring data with reference physiological data to calculate a first similarity; compare motion features with reference motion features to calculate a second similarity; the current user's degree of motion = a × first similarity + b × second similarity, where a and b are preset weights.

[0071] In some embodiments, reference physiological data can be obtained by acquiring physiological monitoring data of users during time periods T1-T2 when multiple consecutive target behaviors are completed, and using the mean of each indicator of the physiological monitoring data of users during T1-T2 as the value of each indicator in the reference physiological data. In some embodiments, reference motion features can be obtained by acquiring motion data of users during time periods T1-T2 when multiple consecutive target behaviors are completed, extracting motion features, and using the mean of each indicator of the motion features of users during T1-T2 as the value of each indicator in the reference motion features. For example, the motion feature could be the time taken for the target behavior; after a preset time since the start of training, the time taken to complete multiple consecutive target behaviors is acquired, and the average time taken for each target behavior is calculated, with the mean used as the reference motion feature.

[0072] In some embodiments, the controller can determine whether to switch the training mode of the fitness equipment based on the level of exercise. For example, in strength training mode, if the user's exercise level is less than a first threshold, the strength training mode is switched to aerobic training mode; in aerobic training mode, if the user's exercise level is greater than a second threshold, the aerobic training mode is switched to strength training mode. Wherein, the first threshold is less than the second threshold. In strength training mode, a lower current exercise level indicates that the user may be fatigued, and resistance should be reduced for relaxation, thus switching from strength training mode to aerobic training mode. Conversely, in aerobic training mode, if the current exercise level is relatively easy for the user, it can be appropriately increased, thus switching from aerobic training mode to strength training mode. The first and second thresholds can be manually set values ​​based on experience.

[0073] In some embodiments, users can set the switching time between the two modes. The switching time can be directly determined based on the user-input training goal according to a preset relationship. The user-input training goal can be pre-set in the system and selected by the user, such as muscle gain or weight loss; or it can be a specific target value input by the user, such as exercise duration or muscle gain weight. The preset relationship can be a pre-set correspondence between training goals, exercise modes, and exercise time in the system. In some embodiments, users can pre-set the switching frequency between strength training mode and aerobic training mode. In some embodiments, users can input the mode through software connected to the fitness equipment. In some embodiments, users can switch modes through buttons, interactive screens, or voice acquisition systems on the fitness equipment.

[0074] In some embodiments, the controller may adjust the resistance module of the fitness equipment in response to the exercise state not meeting preset conditions. Adjusting the resistance module can involve increasing or decreasing the resistance. In some embodiments, the resistance adjustment of the resistance module is related to mode switching. For example, increasing resistance in aerobic training mode, then switching to strength training mode, and further increasing resistance in strength training mode, etc.

[0075] In some embodiments, during strength training mode, after a preset time has elapsed, if the preset condition is a first threshold < the user's level of exercise < a third threshold, the controller controls the resistance module to reduce the resistance, indicating that the conditions for mode switching have not been met, but the user is still quite tired, so the resistance needs to be reduced; if the preset condition is the user's level of exercise > the third threshold, the controller controls the resistance module to increase the resistance, indicating that the conditions for switching have not been met, and the user is in a relatively relaxed state, so the resistance needs to be increased.

[0076] In some embodiments, during aerobic training mode, after a preset time has elapsed, if the preset condition is a fourth threshold < the user's exercise ease level < a second threshold, the controller increases the resistance of the resistance module, indicating that the switching condition has not been met and the user is relatively relaxed, thus requiring increased resistance. If the preset condition is 0 < the user's exercise ease level < a fourth threshold, the controller decreases the resistance of the resistance module, indicating that the user is somewhat tired, thus requiring decreased resistance. Wherein: first threshold < second threshold < third threshold < fourth threshold. The third and fourth thresholds can be manually set based on experience. The resistance adjustment of the resistance module can be obtained through a preset correspondence between the user's exercise intensity and the amount of resistance adjustment. This correspondence can be manually set based on experience.

[0077] Some embodiments in this manual allow the fitness equipment to switch modes and change the resistance of the resistance module based on the intensity of the user's training. This enables the current exercise intensity of the equipment to adapt to the user's current state, meet the customer's exercise needs, prevent the user from being overly fatigued, reduce the risk of injury, and improve the user's exercise experience.
