Description

Technical Field

[0001] This application relates to the technical field of rehabilitation training walking equipment, and more particularly to a sliding device for a ceiling track system. Background Technology

[0002] In the fields of neurorehabilitation and orthopedic rehabilitation, overhead track systems are widely used in patients' walking training to provide safe and controlled weight-reduction support. This system typically consists of a network of tracks mounted on the ceiling or a dedicated support frame, trolleys that slide along the tracks, safety harnesses connecting the trolleys to the patient's torso, and a weight-reduction control system. With an overhead track system, patients can train to stand and walk in a near-normal gait pattern while avoiding secondary injuries from falls. Especially for patients with motor dysfunction such as stroke sequelae, spinal cord injuries, and Parkinson's disease, overhead track systems can effectively improve their balance, muscle strength, and walking endurance, and have become an indispensable piece of equipment in modern rehabilitation medicine.

[0003] In existing overhead track systems, the H-rail sliding device is a common track structure. Its cross-section is H-shaped, consisting of two parallel fixed rails and a moving rail slidably installed between them. The two fixed rails form two symmetrical grooves on the left and right sides. The trolley device can be slidably embedded into the groove of the moving rail using rollers or sliders, achieving smooth sliding along the track direction of the fixed rails. This structure has advantages such as high load-bearing capacity, good guidance, and simple installation and maintenance, and is widely used in hospital rehabilitation centers and professional training facilities. Some high-end systems also integrate electric drive, position sensing, or remote control modules to further improve training efficiency and user experience.

[0004] However, most H-rail sliding devices currently on the market still lack effective braking or locking mechanisms. During rehabilitation training, if a patient suddenly loses balance, experiences spasms, or becomes physically exhausted, the trolley may continue to slide due to inertia and fail to stop in time, increasing the risk of falls or collisions. This safety hazard is particularly prominent on inclined tracks or in scenarios where multiple people share the track. Although some systems attempt to achieve deceleration through external ropes or electromagnetic devices, these solutions are often structurally complex, have delayed responses, and rely on braking directly from the source of sliding motion on the fixed track, making it difficult to meet the clinical need for immediate and reliable braking. Therefore, there is an urgent need for an H-rail sliding device with built-in braking function to significantly improve the safety and reliability of ceiling-mounted rehabilitation systems. Utility Model Content

[0005] This application provides a sliding device for a ceiling track system, which solves the technical problem that existing ceiling track systems' heavy H-rail sliding devices lack effective braking or locking mechanisms.

[0009] In one embodiment, the braking mechanism further includes a drive assembly mounted on the first mounting plate and connected to the slider drive for driving the slider to slide along the third slide rail.

[0010] In one embodiment, a first guide through hole is provided on the first mounting plate, the first guide through hole being located on one side of the third slide rail; the drive assembly includes: a drive motor, mounted on the side of the first mounting plate opposite to the third slide rail, and the output shaft of the drive motor is configured to extend along a first direction; a transmission member, having an angled configuration, having a first connecting part and a second connecting part that are interconnected; the first connecting part passes through the first guide through hole and is provided with a bushing, the bushing being threadedly engaged with the output shaft of the drive motor; the second connecting part is connected to the slider; When the output shaft of the drive motor rotates, it drives the slider to slide along the third slide rail through the transmission component.

[0011] In one embodiment, the second mounting plate is provided with a clearance groove and a mounting groove; the opening of the clearance groove faces the first mounting plate and accommodates the slide assembly; the opening of the mounting groove faces away from the first mounting plate and accommodates the first hinge seat; the second mounting plate is also provided with a second guide through hole on the side of the mounting groove near the first mounting plate, the second guide through hole extends in a third direction, and the first hinge seat slides in the mounting groove in a third direction under the support of the connecting rod.

[0012] In one embodiment, the braking mechanism further includes: a first rolling assembly disposed on the second mounting plate and embedded inside the first slide rail, for rolling contact with the inner wall of the first slide rail so that the braking mechanism can slide along the first slide rail; the first rolling assembly includes: four first pulleys, which are rotatably connected to the second mounting plate in pairs along a first direction and located on both sides of the braking assembly, and each first pulley is rolledly supported on the bottom inner wall of the first slide rail.

[0013] In one embodiment, the sliding connector is T-shaped and has a first mounting portion and a second mounting portion that are perpendicularly connected to each other; the first mounting portion is connected to the braking mechanism, and a third mounting plate is provided on the first mounting portion, the third mounting plate extending into the interior of the corresponding first slide rail; the second mounting portion is locked to the second slide rail by fasteners; the sliding device of the ceiling rail system further includes: a second rolling component, which is disposed on the third mounting plate and embedded in the interior of the first slide rail, for rolling contact with the inner wall of the first slide rail, so that the sliding connector can slide along the first slide rail.

[0015] Compared with existing technologies, the sliding device of the ceiling track system proposed in the above technical solution significantly improves the safety and reliability of rehabilitation training by introducing a braking mechanism on the basis of the traditional H-rail sliding device. Firstly, the sliding device adopts an H-shaped structure design composed of two parallel, spaced-apart first and second slide rails. This not only maintains the advantages of the original H-rail system, such as strong load-bearing capacity and good guidance, but also increases the flexibility of the structure, allowing the suspension host to be adjusted along the first and second directions to better adapt to the gait training needs of different patients. Furthermore, the core innovation of this application lies in the braking mechanism connected to the sliding connector. This braking mechanism can apply frictional resistance to the first slide rail when needed, achieving active buffering or complete braking of the second slide rail's movement. Compared with existing sliding devices that lack effective braking function, this design greatly enhances the safety of patients during rehabilitation training. Especially in emergency situations, such as when the patient loses balance, experiences spasm, or becomes physically exhausted, it can respond quickly and stop sliding in time, preventing the risk of falls or collisions caused by continued sliding due to inertia. Furthermore, compared to external ropes or electromagnetic deceleration devices, this built-in braking mechanism features a simpler overall structure and faster response speed, ensuring immediate braking effectiveness in emergency situations. Therefore, this application not only solves the safety issues existing in the prior art but also provides users with the opportunity and time to readjust their posture, improving overall training efficiency and experience while ensuring the continuity of the training process.

[0016] In summary, the sliding device of the ceiling track system proposed in this application is particularly suitable for use in the fields of neurological rehabilitation and orthopedic rehabilitation. It is of great significance for improving patients' balance, muscle strength and walking endurance, and provides a safer and more reliable solution for rehabilitation treatment.

[0021] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0022] Reference Figure 1As shown in the embodiments of this application, a sliding device for a ceiling track system is proposed. The sliding device may include: two first slide rails 1, arranged parallel and spaced apart and extending along a first direction, for installation on the ceiling; two sliding connectors 2, slidably installed on the two first slide rails 1 respectively; a second slide rail 3, with its two ends respectively connected to the two sliding connectors 2 and located between the two first slide rails 1, and the second slide rail 3 extending along a second direction perpendicular to the first direction, for installation of the suspension host; and two braking mechanisms 4, disposed on the two first slide rails 1, the braking mechanisms 4 being connected to the corresponding sliding connectors 2, for selectively engaging with the first slide rails 1 through friction to brake or buffer the movement of the second slide rail 3 along the first direction.

[0023] Specifically, in the technical solution adopted in this application, the two ends of the second slide rail 3 are slidably mounted on two parallel and spaced-apart first slide rails 1 via independent sliding connectors 2, forming an H-shaped sliding structure. The two first slide rails 1 extend along a first direction, which can be a front-to-back direction, i.e., the walking direction; the second slide rail 3 extends along a second direction perpendicular to the first direction, which can be a left-to-right direction, i.e., the attitude adjustment direction of the suspension unit. The suspension unit is slidably mounted on the second slide rail 3, facilitating user adjustment of walking posture.

[0024] The core of this solution lies in the braking mechanism 4, which is connected to the sliding connector 2 on both first slide rails 1. This braking mechanism 4 can apply frictional resistance to the first slide rail 1 when needed, thereby actively buffering or completely braking the movement of the second slide rail 3 along the first direction. This design is particularly suitable for rehabilitation training scenarios: during normal walking training, the suspension unit can slide freely along the first slide rail 1 to match the user's gait; in case of an emergency or when immediate stopping is required, since the user's control ability may not have fully recovered, the braking mechanism 4 can be activated to gradually slow down the sliding of the second slide rail 3 until it is completely braked on the first slide rail 1. This ensures the safety of the training process and provides the user with an opportunity to readjust their posture or reposition themselves on the second slide rail 3 via the suspension unit, effectively avoiding the risk of accidents caused by the inability to brake in time.

[0025] Furthermore, refer to Figure 2 and Figure 3 As shown, in some embodiments, the braking mechanism 4 includes: a first mounting plate 401 connected to a corresponding sliding connector 2; a second mounting plate 402 erected on the first mounting plate 401 and extending into the interior of a corresponding first slide rail 1; a slide assembly mounted on the first mounting plate 401; a brake assembly movably disposed on the second mounting plate 402; and a connecting rod 408 having a first end 408a and a second end 408b, the first end 408a being hinged to the slide assembly and the second end 408b being hinged to the brake assembly. The sliding of the slide assembly can drive the brake assembly to move relative to the second mounting plate 402 via the connecting rod 408, so that the brake assembly contacts or disengages from the inner wall of the first slide rail 1.

[0026] Specifically, in the technical solution adopted in this application, the first mounting plate 401 serves as the mounting base for the slide assembly, and the second mounting plate 402 serves as the mounting base for the brake assembly, allowing the brake assembly to be installed inside the first slide rail 1. When the brake assembly contacts the inner wall of the first slide rail 1, frictional resistance is generated between the brake assembly and the first slide rail 1, thereby achieving braking of the sliding motion. The two ends of the connecting rod 408 are respectively hinged to the slide assembly and the brake assembly, forming a linkage structure. When the slide assembly moves along its sliding direction, it will cause the first end 408a of the connecting rod 408 to change position, and then drive the brake assembly to move relative to the second mounting plate 402 through the transmission of the connecting rod 408. Thus, the brake assembly can perform the action of contacting or disengaging from the inner wall of the first slide rail 1 according to the position change of the slide assembly: when in contact, it achieves braking or buffering of the second slide rail 3 moving along the first direction; when disengaged, it releases the brake, allowing the second slide rail 3 to slide freely along the first slide rail 1.

[0027] Furthermore, refer to Figure 2 and Figure 3 As shown, in some embodiments, the brake assembly includes: a first hinge seat 409, slidably mounted on a second mounting plate 402 and hinged to the second end 408b of a connecting rod 408, the first hinge seat 409 being slidably limited along a third direction perpendicular to the first mounting plate 401; a support seat 411, mounted on the first hinge seat 409 via an elastic element 410, the elastic element 410 being compressible by elastic force along a third direction; and a brake pad 412, detachably mounted on the side of the support seat 411 opposite to the first hinge seat 409, for contacting the inner wall of the first slide rail 1 to generate braking friction.

[0028] Specifically, in the technical solution adopted in this application, a first hinge shaft 413 is provided on the first hinge seat 409, and the second end 408b of the connecting rod 408 is hinged to the first hinge seat 409 through the first hinge shaft 413. Under the transmission action of the connecting rod 408, the first hinge seat 409 can slide on the second mounting plate 402 in a direction away from or close to the first mounting plate 401, i.e., in a third direction. The support seat 411 is installed on the side of the first hinge seat 409 away from the first mounting plate 401 by means of an elastic element 410, and the brake pad 412 is detachably installed on the support seat 411. The elastic element 410 can be a compression spring. When the brake pad 412 contacts the inner wall of the first slide rail 1, the elastic element 410 is compressed between the support seat 411 and the first hinge seat 409, so that a flexible contact is formed between the braking mechanism 4 and the first slide rail 1. This design effectively mitigates potential shocks and jerks during braking, providing users with a smoother braking process and ample reaction and adaptation time, thereby avoiding the risk of increased imbalance in the first direction due to braking operations. In actual use, when the first hinge seat 409 moves away from the first mounting plate 401 in a third direction, the brake pad 412, supported by the elastic element 410, flexibly engages with the inner wall of the first slide rail 1, generating sufficient frictional resistance, thus effectively braking the sliding motion in the first direction.

[0029] Furthermore, refer to Figure 2 and Figure 3 As shown, in some embodiments, the slide assembly includes: a third slide rail 405, fixed to a first mounting plate 401 and extending in a first direction; a slider 406, slidably mounted on the third slide rail 405; and a second hinge seat 407, fixed to the slider 406 and hinged to the first end 408a of the connecting rod 408. The slider 406 drives the second hinge seat 407 to slide, forming a first work station and a second work station. When the second hinge seat 407 is in the first work station, the connecting rod 408 is inclined relative to the first mounting plate 401. When the second hinge seat 407 is in the second work station, the connecting rod 408 is vertical relative to the first mounting plate 401.

[0030] Specifically, in the technical solution adopted in this application, the third slide rail 405 is fixed to the first mounting plate 401 as a guide reference, and its extension direction is parallel to the first slide rail 1, thereby defining the motion axis of the slide assembly. The slider 406 and the third slide rail 405 form a linear motion pair to ensure that its sliding trajectory is accurate and stable. The second hinge seat 407 fixed on the slider 406 serves as the driving end of the connecting rod 408. A second hinge shaft 414 is provided on the second hinge seat 407 to hinge with the first end 408a of the connecting rod 408, so as to convert the horizontal linear motion of the slider 406 into the swing of the connecting rod 408. When the slider 406 is driven to slide, so that the second hinge seat 407 is in the second position, the connecting rod 408 turns to a vertical state. At this time, its axial component pushes the brake assembly to perform the braking action. When the second hinge seat 407 moves to the first position, the connecting rod 408 is in an inclined state, and its axial thrust on the brake assembly is released, and the brake is released accordingly. This "tilt-vertical" position change of the linkage 408 is the core technical principle for achieving the "contact-disengagement" state switching of the brake assembly.

[0031] Furthermore, refer to Figure 2 and Figure 3 As shown, in some embodiments, the braking mechanism 4 further includes a drive assembly mounted on the first mounting plate 401 and drivenly connected to the slider 406 for driving the slider 406 to slide along the third slide rail 405.

[0032] Furthermore, in some embodiments, a first guide through hole 401a is provided on the first mounting plate 401, and the first guide through hole 401a is located on one side of the third slide rail 405. The drive assembly includes: a drive motor 403, mounted on the side of the first mounting plate 401 opposite to the third slide rail 405, with the output shaft of the drive motor 403 extending along a first direction; a transmission member 404, which has an angled configuration and has a first connecting part 404a and a second connecting part 404b that are connected to each other; the first connecting part 404a passes through a first guide hole 401a and is provided with a bushing 404c, which is threadedly engaged with the output shaft of the drive motor 403; and the second connecting part 404b is connected to the slider 406. When the output shaft of the drive motor 403 rotates, it drives the slider 406 to slide along the third slide rail 405 through the transmission component 404.

[0033] Specifically, in the technical solution adopted in this application, the drive assembly provides the power source for the automatic operation of the slide assembly. Its installation layout makes full use of space. Specifically, the drive motor 403 is placed below the first mounting plate 401, with its output shaft direction aligned with the sliding direction, resulting in a compact structure. The angled configuration of the transmission component 404 is crucial; it is connected between the drive motor 403 and the slide assembly via a first guide passing through the first mounting plate 401. The bushing 404c on its first connecting part 404a forms a threaded transmission pair with the motor output shaft. When the drive motor 403 starts, its output shaft rotates, driving the transmission component 404 to generate precise linear displacement along its axial direction (i.e., the first direction) through the threaded engagement. This linear displacement is directly transmitted to the slider 406 through the second connecting part 404b, thereby converting it into stable sliding of the slider 406 along the third slide rail 405. The entire transmission process efficiently and precisely converts the rotational motion of the drive motor 403 into the linear motion required by the slide.

[0034] In some embodiments, in order to limit the maximum displacement distance of the transmission member 404 on the output shaft of the drive motor 403, two sensing components 416 connected to the drive motor 403 can be provided at the bottom of the first mounting plate 401. The two sensing components 416 are located on opposite sides of the first guide hole 401a along the first direction. When the transmission member 404 moves into the sensing area of ​​one of the sensing components 416, the sensing component 416 sends an electrical signal to the drive motor 403 indicating that the target position has been reached. After receiving the electrical signal, the drive motor 403 stops the rotation of its output shaft.

[0035] Furthermore, refer to Figure 3 As shown, in some embodiments, the second mounting plate 402 is provided with a clearance groove 402a and a mounting groove 402b; the opening of the clearance groove 402a faces the first mounting plate 401 and accommodates the slide assembly; the opening of the mounting groove 402b faces away from the first mounting plate 401 and accommodates the first hinge seat 409; the second mounting plate 402 is also provided with a second guide through hole 402c on the side of the mounting groove 402b near the first mounting plate 401, the second guide through hole 402c extends in a third direction, and the first hinge seat 409 slides in the mounting groove 402b in a hinged manner with the second guide through hole 402c, so that the first hinge seat 409 slides in the mounting groove 402b in a third direction under the support of the connecting rod 408.

[0036] Specifically, in the technical solution adopted in this application, the second mounting plate 402 achieves structural integration and precise guidance of movement by opening grooves with different functions. The clearance groove 402a is open at the top, providing a space for the slide assembly, allowing the slide assembly to be positioned directly below the brake assembly, avoiding motion interference. The mounting groove 402b is open at the bottom, used to accommodate and constrain the first hinge seat 409 of the brake assembly. Specifically, in the non-braking state, the brake assembly can be arranged overlapping in the second mounting plate 402 through the mounting groove 402b without increasing the thickness of the second mounting plate 402, avoiding motion interference of the braking mechanism 4 in the non-braking state. In particular, a second guide through hole 402c extending in a third direction is provided in the second mounting plate 402 below the mounting groove 402b, so that the first hinge seat 409 and the second mounting plate 402 form a sliding fit. The second guide through hole 402c serves as a sliding guide for the first hinge seat 409, ensuring that it can only move in a strictly vertical (third) direction, eliminating sway. Specifically, this can be achieved by the second guide through hole 402c also cooperating with the first hinge shaft 413, that is, the first hinge shaft 413 passes through the second guide through hole 402c. Therefore, the swing of the connecting rod 408 can be converted into the pure vertical sliding of the first hinge seat 409 along the second guide through hole 402c in the mounting groove 402b, which is ingenious in structure and provides precise guidance.

[0037] Furthermore, refer to Figure 3 As shown, in some embodiments, the braking mechanism 4 further includes: a first rolling assembly disposed on the second mounting plate 402 and embedded inside the first slide rail 1, for rolling contact with the inner wall of the first slide rail 1, so that the braking mechanism 4 can slide along the first slide rail 1; The first rolling assembly includes four first pulleys 415, which are rotatably connected to the second mounting plate 402 in pairs along the first direction and are located on both sides of the brake assembly. Each first pulley 415 is rolled and supported on the bottom inner wall of the first slide rail 1.

[0038] Specifically, in the technical solution adopted in this application, the first rolling assembly ensures the smooth movement of the braking mechanism 4 within the first slide rail 1. Four first pulleys 415 are divided into two groups and symmetrically arranged on both sides of the braking assembly. This arrangement forms stable support points at both ends of the second mounting plate 402, ensuring the balance of the braking mechanism 4 during suspension and movement. Each first pulley 415 forms rolling contact with the bottom inner wall of the first slide rail 1, converting sliding friction into rolling friction, greatly reducing movement resistance. All first pulleys 415 collectively constrain the position of the second mounting plate 402 in the vertical plane, while allowing it to roll freely in the first direction, thus enabling the entire braking mechanism 4 to easily move with the sliding connector 2, and quickly establish a relatively fixed friction point when braking is required.

[0039] Furthermore, refer to Figure 1 and Figure 4 As shown, in some embodiments, the sliding connector 2 is T-shaped and has a first mounting portion 2a and a second mounting portion 2b that are perpendicularly connected to each other; the first mounting portion 2a is connected to the braking mechanism 4, and a vertical third mounting plate 5 is provided on the first mounting portion 2a, the third mounting plate 5 extending into the interior of the corresponding first slide rail 1; the second mounting portion 2b is locked to the second slide rail 3 by fasteners. The sliding device of the ceiling track system also includes a second rolling component, which is disposed on the third mounting plate 5 and embedded inside the first slide rail 1, for rolling contact with the inner wall of the first slide rail 1 so that the sliding connector 2 can slide along the first slide rail 1.

[0040] Specifically, in the technical solution adopted in this application, the sliding connector 2 adopts a T-shaped structure, realizing functional integration and force transmission in two directions. Its first mounting part 2a, used to connect the braking mechanism 4 and located below the first slide rail 1, is a key component for bearing and transmitting horizontal braking force. The third mounting plate 5 on it serves as the base for mounting the second rolling assembly. The second mounting part 2b is rigidly locked to the second slide rail 3 via fasteners (such as bolts), ensuring no relative movement between the second slide rail 3 and the sliding connector 2, allowing the braking force generated by the braking mechanism 4 to be effectively and losslessly transmitted to the second slide rail 3. Integrating the load and braking force of the second slide rail 3 and the reaction force of the first slide rail 1 into the entire sliding connector 2, it is the core load-bearing and force-transmitting component connecting the sliding system and the braking system.

[0041] Furthermore, refer to Figure 4 As shown, in some embodiments, the second rolling assembly includes: four second pulleys 6, rotatably connected to the third mounting plate 5 in pairs along the first direction, with the two sets of second pulleys 6 rollingly supported on the inner walls of both sides of the first slide rail 1; four third pulleys 7, rotatably connected to the third mounting plate 5 in pairs along the first direction, with the two sets of third pulleys 7 located between the two sets of second pulleys 6, and rollingly supported on the bottom inner wall of the first slide rail 1; and four fourth pulleys 8, rotatably connected to the third mounting plate 5 in pairs along the first direction, with the two sets of fourth pulleys 8 located between the two sets of third pulleys 7, and rollingly supported on the top inner wall of the first slide rail 1.

[0042] Specifically, in the technical solution adopted in this application, the second rolling component uses multiple sets of pulleys to form a clamping rolling contact with the inner wall of the first slide rail 1 from multiple directions, constituting an efficient and stable guiding and bearing system for the sliding connector 2. Four second pulleys 6 press against the left and right inner walls of the first slide rail 1, mainly providing horizontal guidance to prevent the connector from swaying left and right. Four third pulleys 7 are supported on the bottom inner wall of the slide rail, mainly bearing the vertical load and transferring the weight of the second slide rail 3 and the suspension host to the first slide rail 1. Four fourth pulleys 8 press against the top inner wall of the slide rail, cooperating with the third pulleys 7 to jointly prevent the connector from tipping over or jumping in the vertical plane. This all-round rolling constraint design of "both sides-bottom-top" ensures that the sliding connector 2 can slide smoothly along the first direction while maximally suppressing undesirable movements in the other five degrees of freedom, ensuring that the entire sliding device operates smoothly and without jamming.
