TECHNICAL FIELD
[0001] The utility model relates to a kind of training equipment, specifically a lower limb training mechanism of training equipment. BACKGROUND
[0002] In the existing training equipment, most training actions require users to lift weights, however, the human body will exert a force against gravity on the lower limbs when lifting weights, thereby potentially causing harm to the user's body. Isometric exercise refers to a form of exercise in which the length of the muscle remains unchanged during contraction, without joint movement. This exercise mode mainly resists fixed resistance by increasing muscle tension, and the muscle fiber does not shorten during muscle contraction, thereby increasing muscle tension without changing muscle length. Given the characteristics of isometric exercise, a training device can be designed that greatly reduces the risk of injury to the user's lower limbs. SUMMARY
[0003] The purpose of the utility model is to overcome the deficiencies of the prior art, and to provide a lower limb training mechanism of training equipment. When the lower limb training mechanism is applied, the user always controls the force exerted by and required to be borne by the lower limbs, thereby avoiding potential harm to the lower limbs.
[0004] The purpose of the utility model is achieved as follows:
[0005] A lower limb training mechanism of training equipment includes a device base, a lower limb training support suitable for a user to sit on, and a force sensor for collecting force data. The lower limb training support is movably arranged on the device base, and the force sensor is arranged between the lower limb training support and the device base. The data output end of the force sensor is communicatively connected to a data analysis and processing module. When the user's lower limbs act on the lower limb training support relative to the device base, the force of the user's lower limbs acts on the force sensor, and the force sensor collects the force data of the user's lower limbs.
[0006] As a specific solution, one end of the lower limb training support is hinged to the device base. When the lower limb training support swings relative to the device base, the force sensor is subjected to a force in the stretching direction or the compression direction.

The support assembly includes a first adapter component and a second adapter component. One end of the force sensor is hinged to the lower limb training support through the first adapter component, and the other end is hinged to the device base through the second adapter component. The first adapter component and the second adapter component are coaxially connected.
[0008] As another specific solution, a fall-preventing support is provided on the device base. The fall-preventing support controls the movement of the lower limb training support within a set range. When the lower limb training support exceeds the set movement range, the fall-preventing support supports the lower limb training support.
[0009] As a further specific solution, a limiting slot is arranged on the anti-falling support, and a limiting rod is arranged on the lower limb training support and arranged in the limiting slot; the limiting rod moves in the limiting slot along with the movement of the lower limb training support.
[0010] As a further specific solution, the limiting slot extends horizontally, and the two extending ends and the front end are respectively arranged with openings; the limiting rod extends horizontally, and the two extending ends respectively pass through the two extending ends of the limiting slot.
[0011] As a further specific solution, a foot pedal is arranged on the lower limb training support, and the foot pedal is resettable relative to the lower limb training support.
[0012] As a further specific solution, a handrail is arranged on the lower limb training support for the user to hold.
