Abstract

This invention discloses an ankle joint training device. A maze disc is connected to a base via a vertical rod mechanism. The vertical rod mechanism includes a foot pedal and several vertical rods. One end of each vertical rod is hinged to the maze disc, and the other end passes through the foot pedal and is mounted on the base. Each vertical rod is hinged to the foot pedal, which is also hinged to the base. Several adjustable damping mechanisms are mounted on the base, with the working end of each mechanism abutting against the foot pedal. The foot pedal supports the user's foot. The user drives the foot pedal to overcome the damping force of the adjustable damping mechanisms through ankle movement, and changes the angle of the maze disc via the vertical rods, thereby causing the training ball to roll along the track within the maze disc under the influence of gravity. This invention focuses on ankle joint movement during training, avoiding unnecessary extra movement, improving stability, reducing the risk of tipping over, and enhancing the training effect of the ankle joint. Simultaneously, it reduces the device's requirements for the user's reaction speed and rehabilitation conditions.

Description

Technical Field

[0001] This invention belongs to the field of ankle joint training technology, and specifically relates to an ankle joint training device. Background Technology

[0002] Ankle training devices can effectively improve ankle joint health and achieve comprehensive rehabilitation. Currently, there are many types of ankle training devices, but most lack fun and subjective engagement, and a few with software are expensive. Some existing training devices (such as CN 220002898 U) have a relatively fixed connection between the vertical support and the base. During use, in addition to ankle movement, there is also horizontal leg movement, resulting in a large range of motion for the maze disc, posing a risk of tipping over and creating safety hazards. This also affects the training effect on the ankle joint. Furthermore, because the movement of the maze disc relies entirely on the user's leg and ankle strength control, it places high demands on the user's reaction speed and rehabilitation conditions, limiting its applicability and hindering its widespread adoption. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides an ankle joint training device that focuses on ankle joint movement during training, avoiding unnecessary extra movement, improving stability, reducing the risk of tipping over, and enhancing the training effect of the ankle joint.

[0021] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0022] like Figures 1-4 As shown, an ankle joint training device includes: a base 1, a vertical rod mechanism, and a maze disk 4. The maze disk 4 is connected to the base 1 via the vertical rod mechanism. A training ball is placed inside the maze disk 4 and rolls along a track within the maze disk 4. The vertical rod mechanism includes a foot pedal 2 and several vertical rods 3. One end of each vertical rod 3 is hinged to the maze disk 4, and the other end passes through the foot pedal 2 and is mounted on the base 1. Each vertical rod 3 is hinged to the foot pedal 2. The foot pedal 2 is hinged to the base 1. Several adjustable damping mechanisms are installed on the base 1, and the working end of each adjustable damping mechanism abuts against the foot pedal 2. The foot pedal 2 is used to support the user's foot. The user drives the foot pedal 2 to overcome the damping force of the adjustable damping mechanism through the movement of the ankle, and changes the angle of the maze disk 4 through the vertical rods 3, thereby causing the training ball to roll along the track within the maze disk 4 under the action of gravity.

[0023] The chassis 1 includes a lower cover plate 11, a fixed plate 12 and an upper cover plate 18; one side of the fixed plate 12 is connected to the lower cover plate 11 and the other side is connected to the upper cover plate 18; the fixed plate 12, the lower cover plate 11 and the upper cover plate 18 form a receiving cavity.

[0024] The foot pedal 2 is hinged to the chassis 1 via a universal support column 19 or a ball joint.

[0025] The adjustable damping mechanism includes an adjustable damping spring 16, which is located in the receiving cavity. The adjusting end of the adjustable damping spring 16 is mounted on the lower cover plate 11, and the working end of the adjustable damping spring 16 passes through the first through hole on the upper cover plate 18 and abuts against the foot pedal 2.

[0026] The adjustable damping mechanism also includes an adjustment knob 13, which is located in the receiving cavity. The working end of the adjustment knob 13 is mounted on the lower cover plate 11, and the operating end of the adjustment knob 13 passes through the second through hole on the upper cover plate 18 and is located between the upper cover plate 18 and the foot pedal 2. The working end of the adjustment knob 13 is equipped with a track wheel 14, which is connected to the track wheel 2 mounted on the adjusting end of the adjustable damping spring 16 via the track 15.

[0027] In this invention, four adjustable damping springs 16 are placed vertically, with their heads (working ends) pressing against the foot pedal 2. The cylinder body is fixed to the lower cover plate 11, and the tail adjustment part (adjustment end) is equipped with a second track wheel. The second track wheel is connected to the first track wheel 14 installed at the working end of the adjustment knob 13 via a track 15, so that the resistance of the adjustable damping springs 16 can be controlled by the operation end of the adjustment knob 13.

[0028] The cylinder of the adjustable damping spring 16 is fixed to the lower cover plate 11 by a nut; the head of the adjustable damping spring 16 presses against the foot pedal 2. When the foot pedal 2 is tilted by the user's ankle movement, the adjustable damping spring 16 is compressed to generate resistance; the rear gear adjustment part of the adjustable damping spring 16 is equipped with a track wheel 2, which is connected to the track wheel 1 below the adjustment knob 13 through the track 15, so that the adjustment knob 13 controls the resistance of the adjustable damping spring 16; the four adjustable damping springs 16 are evenly distributed (one in front, one in the back, one in the left, and one in the right), and the resistance can be adjusted independently. The user can freely adjust the damping force of the adjustable damping spring 16 according to his own situation and the degree of ankle recovery.

[0029] The cross guide rail slider assembly 17 is located in the receiving cavity and is mounted on the lower cover plate 11. The vertical rod 3 passes through the third through hole on the upper cover plate 18 and is connected to the cross guide rail slider assembly 17.

[0030] In this invention, four cross-shaped guide rail slider assemblies 17 are respectively fixed on the lower cover plate 11, always remaining horizontal, and can slide independently forward, backward, left, and right; the vertical rod 3 passes through the fisheye bearing on the foot pedal 2 and is vertically installed on the four cross-shaped guide rail slider assemblies 17. The upper end of the vertical rod 3 is connected to a universal ball bearing and installed on the outer ring of the maze disk 4.

[0031] In this invention, the vertical rod 3 has a multi-segment structure, with a nylon sleeve 32 and an adjusting buckle 31 defining the relative position between adjacent segments. The vertical rod 3 has three segments: one segment between the chassis 1 and the foot pedal 2, with one end connected to the cross guide slider assembly 17 and the other end connected to the fisheye bearing on the foot pedal 2; and a clip between the upper two segments between the foot pedal 2 and the labyrinth disc 4, allowing for height adjustment; simultaneously, a nylon sleeve 32 is used to reduce friction and noise.

[0032] In this invention, the maze disk 4 can be quickly replaced, and there are at least three types of maze disks: linear maze disks, rotating maze disks, and omnidirectional maze disks, such as... Figure 5 As shown, users can freely choose the type of maze disc according to their own situation and the degree of ankle recovery, which can improve the training effect, enhance entertainment, and improve the user experience.

[0033] This invention employs a synchronized top-bottom structure, ensuring the maze disc remains directly above the foot pedal and that the two planes remain parallel. Therefore, the user can control the foot pedal angle via their ankle, thereby controlling the maze disc angle and the ball within it. Users can adjust the resistance and maze disc height according to their individual needs. The cross-rail slider combination reduces the horizontal range of motion of the user's legs, ensuring that the force controlling the foot pedal is primarily controlled by ankle movement. This design reduces the risk of tipping and improves ankle training effectiveness. Placing the maze disc in front of the trainee enhances visibility and provides a better user experience. An adjustable damping mechanism allows users to freely adjust the damping force of the damping spring according to their own conditions (such as reaction speed and ankle recovery level), further improving ankle training effectiveness and enhancing the user's experience.

[0034] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
