Description

Technical Field

[0001] This utility model belongs to the field of rehabilitation equipment technology, specifically relating to an angled treadmill and walking and balance rehabilitation equipment. Background Technology

[0002] Patients with walking and balance disorders often require rehabilitation equipment for rehabilitation training. With the advancement and development of technology, rehabilitation equipment that combines treadmills and six-degree-of-freedom platforms has been widely used because it can provide complex and varied movement paths and patterns. It can not only simulate basic reciprocating movements, but also precisely control the position and orientation of the equipment in three-dimensional Cartesian space, thereby better adapting to and supporting the specific rehabilitation needs of patients.

[0003] However, in existing technologies, the treadmills used in six-degree-of-freedom running platforms employ traditional structures, such as... Figure 1 As shown, the treadmill's drive unit is located at the front end of the running belt. A drive motor drives the running belt, with the drive wheel on the motor and the driven wheel on the treadmill positioned one behind the other, protected by a front cover. This design results in a relatively long overall structure for the treadmill, significantly limiting its use in space-constrained rehabilitation equipment. Furthermore, a large gap exists between the front cover and the running belt, posing a potential risk of foot pinching when performing backward movements on the treadmill, a safety hazard particularly for rehabilitation patients.

[0004] Therefore, there is an urgent need to design a treadmill that can save space and eliminate the risk of foot pinching. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides an angled treadmill and a walking and balance rehabilitation device. By setting the drive motor of the treadmill and the drive roller of the running belt vertically, the length dimension of the treadmill is greatly reduced, thereby saving treadmill space. Furthermore, by setting the running belt plane to be higher than the baffle of the treadmill, the risk of foot pinching is eliminated, thus solving the existing technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an angled treadmill, comprising a frame body, an active roller, a driven roller, a running belt, and a drive motor. The active roller and the driven roller are respectively disposed at both ends of the frame body. The running belt is pre-tensioned and frictionally driven connected to the active roller and the driven roller, and the running belt tightly wraps around the surfaces of the active roller and the driven roller. A driven pulley is provided on the end face of the active roller, and an active pulley is provided on the output shaft of the drive motor. The active pulley is disposed directly below the driven pulley, and the active pulley and the driven pulley are connected by a synchronous belt.

[0007] Furthermore, the active roller or driven roller has a gap with the corresponding end of the frame body in the running forward direction, and the gap is covered by a baffle set on the frame body, and the running belt plane is higher than the baffle plane.

[0008] Furthermore, both ends of the driving roller and the driven roller are tapered structures, and the frame body is provided with an anti-deviation tensioning structure, which is symmetrically arranged on the left and right sides of the lower surface of the belt.

[0009] Furthermore, force sensors are installed at both ends of the bottom of the main frame.

[0010] Furthermore, a motor mounting bracket is provided on the side of the main frame near the drive roller, and a motor mounting plate is provided on the motor mounting bracket, on which the drive motor is mounted.

[0011] Furthermore, the drive motor is a servo motor.

[0012] Furthermore, the drive motor is equipped with a protective cover, which is fixedly mounted on the bottom of the main frame body.

[0013] Furthermore, the running belt includes a left running belt and a right running belt, which are driven by independent drive rollers, driven rollers and drive motors, respectively.

[0014] This utility model also provides a walking and balance rehabilitation device, including a six-degree-of-freedom platform and the aforementioned angled treadmill, wherein the angled treadmill is mounted on the six-degree-of-freedom platform.

[0015] Furthermore, the six-degree-of-freedom platform is either a push rod type six-degree-of-freedom platform or a pendulum type six-degree-of-freedom platform.

[0016] Compared with the prior art, the beneficial effects of this utility model are: This utility model of an angled treadmill reduces the treadmill's length by vertically aligning the drive wheel of the motor with the drive roller of the running belt, thus saving space and significantly reducing the requirements for the work area. Furthermore, by setting the running belt plane higher than the treadmill's side rails, the risk of feet getting caught in the treadmill during forward or backward movements is eliminated. In addition, a large-angle bearing anti-deviation structure further limits the lateral offset of the running belt, allowing the left and right running belts to come closer together, greatly reducing the gap between them and improving training comfort and safety.

Detailed Implementation Example 1

[0025] Combination Figure 2-6 The folding treadmill of this embodiment includes a frame body 10, an active roller 21, a driven roller 22, a running belt 30, and a drive motor 40. The active roller 21 and the driven roller 22 are respectively disposed at both ends of the frame body 10. The running belt 30 is pre-tensioned and frictionally driven connected to the active roller 21 and the driven roller 22. The running belt 30 tightly wraps around the surfaces of the active roller 21 and the driven roller 22. The end face of the active roller 21 is provided with a driven pulley 52. ​​The output shaft of the drive motor 40 is provided with an active pulley 51. The active pulley 51 is disposed directly below the driven pulley 52. ​​The active pulley 51 and the driven pulley 52 are connected by a synchronous belt 60.

[0026] In a preferred embodiment, the running belt 30 includes a left running belt 31 and a right running belt 32, which are driven by independent drive rollers 21 and 22, and a drive motor 40, respectively. Specifically, the left running belt 31 is pre-tensioned and friction-driven connected to the drive rollers 21 and 22, tightly wrapping around their surfaces, and is driven by the drive motor 40. The right running belt 32 is also pre-tensioned and friction-driven connected to the other drive rollers 21 and 22, tightly wrapping around their surfaces, and is driven by the drive motor 40.

[0027] In this preferred embodiment, the active roller 21 or driven roller 22 has a gap with the corresponding end of the frame body 10 in the running direction. This gap is covered by a baffle 13 on the frame body 10, and the plane of the running belt 30 is higher than the plane of the baffle 13. Since the baffles 13 at both ends of the treadmill are lower than the plane of the running belt 30, the risk of the treadmill pinching the feet during forward or backward movement is effectively eliminated.

[0028] In this preferred embodiment, both ends of the active roller 21 and the driven roller 22 are tapered structures. The tapered structure prevents the running belt 30 from deviating. The frame body 10 is provided with an anti-deviation tensioning structure 70, which is symmetrically arranged on both sides of the lower surface of the running belt 30. The lower surface of the running belt 30 refers to the surface of the running belt 30 that is relatively downward when it is in a ring-shaped state during the frictional drive of the active roller 21 and the driven roller 22. Specifically, in this embodiment, four anti-deviation tensioning structures 70 are provided, one set at each end near the active roller 21 and the driven roller 22. This embodiment adds a large-angle bearing anti-deviation structure to the tapered anti-deviation structure of the active roller 21 and the driven roller 22, further limiting the lateral deviation distance of the running belt during movement. For a dual-track treadmill, this allows the left running belt 31 and the right running belt 32 to be closer together, greatly reducing the gap between them and improving training comfort and safety.

[0029] In this preferred embodiment, force sensors 80 are provided at both ends of the bottom of the frame body 10. Specifically, two force sensors 80 are respectively provided at the front and rear ends of both sides of the bottom of the treadmill, with the two force sensors 80 on the same side and at the same end placed side by side. That is, for a dual-belt treadmill, force sensors 80 are respectively provided at the bottom positions corresponding to the left running belt 31 and the right running belt 32. The force sensors 80 can accurately measure the ground reaction force on the left and right feet of the patient during walking, providing reliable data support for rehabilitation assessment.

[0030] In a preferred embodiment, the frame body 10 has a motor mounting bracket 11 facing downward on the side near the drive roller 21, and a motor mounting plate 12 is provided on the motor mounting bracket 11, and the drive motor 40 is mounted on the motor mounting plate 12.

[0031] In this preferred embodiment, the drive motor 40 is a servo motor. Due to its ultra-precise speed and position control capabilities, the servo motor perfectly matches the stringent requirements of rehabilitation training for "stability, controllability, and dynamic response," and is particularly suitable for scenarios requiring fine adjustment, such as nerve injury and postoperative gait correction, thus being more beneficial to patient rehabilitation.

[0032] In a preferred embodiment, the drive motor 40 is provided with a protective cover 41, which is fixedly installed at the bottom of the frame body 10.

[0033] In this embodiment of the angled treadmill, the driving pulley 51 on the output shaft of the drive motor 40 and the driven pulley 52 on the driving roller 21 of the running belt 30 are positioned above and below each other and connected by a synchronous belt 60. This reduces the length of the treadmill, making it suitable for more confined spaces. Simultaneously, the design of the running belt 30 extending above the baffle 13 effectively eliminates the risk of foot pinching during forward or backward movement. Example 2

[0034] The walking and balance rehabilitation equipment in this embodiment includes a six-degree-of-freedom platform and the angled treadmill from Embodiment 1, wherein the angled treadmill is mounted on the six-degree-of-freedom platform. Compared to existing treadmills, the angled treadmill used in this embodiment has a significantly reduced dimension in the treadmill's length direction, reducing space requirements and the space requirements for the installation site of the rehabilitation equipment, thus improving its applicability.

[0035] Preferably, in this embodiment, the six-degree-of-freedom platform is a pushrod-type six-degree-of-freedom platform or a pendulum-type six-degree-of-freedom platform. Specifically, in this embodiment, the pushrod-type six-degree-of-freedom platform, due to its low height, can achieve an even lower initial height by embedding the treadmill into it, saving space in both length and height, further reducing the space requirements for rehabilitation equipment, and the low height is convenient for patients with limited mobility or special physical conditions.
