Description

Technical Field

[0001] This application relates to the technical field of limb rehabilitation training equipment, and more particularly to a lumbar protection device and a gait training device. Background Technology

[0002] Gait rehabilitation training equipment is a medical assistive device specifically designed to help patients restore lower limb motor function. It is widely used in neurological and orthopedic rehabilitation. Common gait rehabilitation training equipment mainly includes walking treadmills and training devices with foot pedals. These devices assist patients in repetitive, rhythmic gait training by simulating natural walking patterns, thereby promoting neuroplasticity and muscle function recovery. This type of equipment is primarily used for patients with gait disorders caused by neurological diseases such as stroke, spinal cord injury, cerebral palsy, and Parkinson's disease, or musculoskeletal disorders, helping them rebuild gait patterns, enhance muscle strength and balance, and improve their daily living activities.

[0003] To ensure patient safety when using gait rehabilitation training equipment, existing technologies commonly employ a protective measure: having the patient wear a specialized safety vest. This vest is typically connected to an upper support structure via straps, providing upward traction to prevent falls or injuries should the patient lose balance. This protective method improves training safety to some extent, allowing patients to perform gait training in a more stable environment while also reducing the therapist's workload.

[0004] However, existing vest-style protective methods still have many shortcomings. First, the vest structure is too cumbersome to put on, which is not only time-consuming but also increases the workload of medical staff. Second, the vest mainly provides overall upward traction protection but cannot provide effective support for the patient's lower back, which can easily lead to lower back collapse or poor posture during training, thus affecting the training effect and even causing secondary injuries. Therefore, there is an urgent need to propose a more reasonable and efficient protective structure to improve the support for the lower back in gait rehabilitation training equipment and to improve convenience by reducing the difficulty of wearing the protective structure.

[0049] 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.

[0050] Reference Figure 1 and Figure 2 As shown, an embodiment of this application proposes a lumbar support device, which may include: a support bracket 1, which has a U-shaped structure and an opening for the user to enter and exit; a flip-up frame tube 2, which is disposed at the opening of the support bracket 1 and has a first connecting end 21 and a second connecting end 22; a rotating mechanism 3, which connects the support bracket 1 and the first connecting end 21, and flips the frame tube 2 at the opening of the support bracket 1 through the rotating mechanism 3; a first protective mechanism 5, which is disposed on the flip-up frame tube 2 and located between the first connecting end 21 and the second connecting end 22, for supporting the user's lower back; a second protective mechanism 6, which is disposed on the support bracket 1 and is arranged opposite to the opening on the support bracket 1, for supporting the user's abdomen; and a locking mechanism 4, which has a first state and a second state; when the locking mechanism 4 is in the first state, the support bracket 1 and the second connecting end 22 are connected through the locking mechanism 4; when the locking mechanism 4 is in the second state, the support bracket 1 and the second connecting end 22 are separated through the locking mechanism 4.

[0051] Specifically, in the technical solution adopted in this application, the flip-frame tube 2 is installed at the opening of the U-shaped support bracket 1 via a rotating mechanism 3 to form a ring frame, preferably a rectangular frame. The flip-frame tube 2 can be flipped on the support bracket 1 based on the first connecting end 21 via the rotating mechanism 3 to open and close the opening on the support bracket 1. The second connecting end 22 of the flip-frame tube 2, away from the rotating mechanism 3, is connected to the support bracket 1 via a locking mechanism 4. When the locking mechanism 4 connects the flip-frame tube 2 and the support bracket 1, it restricts the flip-frame tube 2 from flipping on the support bracket 1 based on the rotating mechanism 3, so that the flip-frame tube 2 can be closed on the opening of the support bracket 1, which is the first state mentioned above. When it is necessary for the flip-frame tube 2 to flip and open the opening of the support bracket 1, the locking mechanism is used to open the opening. The fixing mechanism 4 disconnects the connection between the flip frame tube 2 and the support bracket 1, which is the second state described above. In this application, the first protective mechanism 5 is disposed on the flip frame tube 2, located between the first connecting end 21 and the second connecting end 22, while the second protective mechanism 6 is disposed on the support bracket 1. When the flip frame tube 2 is closed at the opening of the support bracket 1, the first protective mechanism 5 and the second protective mechanism 6 are arranged opposite to each other, so that the first protective mechanism 5 can support the user's lower back, and the second protective mechanism 6 can support the user's abdomen, thereby providing support force to the user in a front and back support manner. When in use, the user needs to move into the support bracket 1. The connection between the flip frame tube 2 and the support bracket 1 can be released by the locking mechanism 4, and the flip frame tube 2 can be rotated to flip on the support bracket 1 through the rotating mechanism 3 to open the opening on the support bracket 1. The user can then enter the support bracket 1 through the opening. At this time, the second protective mechanism 6 can face the user's abdomen. Rotate the flip frame tube 2 back to its original position, and the flip frame tube 2 is connected to the support bracket 1 through the locking mechanism 4 so that the first protective mechanism 5 can face the user's waist and back.

[0052] Furthermore, refer to Figure 1 and Figure 2 As shown, in some embodiments, the support bracket 1 includes: a mounting bracket tube 11, a second protective mechanism 6 disposed on the mounting bracket tube 11; a first connecting bracket tube 12 connected to one end of the mounting bracket tube 11, the first connecting end 21 being connected to the first connecting bracket tube 12 via a rotating mechanism 3; and a second connecting bracket tube 13 connected to the other end of the mounting bracket tube 11, the second connecting end 22 being connected to the second connecting bracket tube 13 via a locking mechanism 4.

[0053] Specifically, in the technical solution adopted in this application, the support bracket 1 may include: a mounting bracket tube 11 and a first connecting bracket tube 12 and a second connecting bracket tube 13 respectively connecting the two ends of the mounting bracket tube 11, so that the support bracket 1 can form the rectangular frame with an opening mentioned in the above embodiment. The opening of the support bracket 1 is located between the ends of the first connecting frame tube 12 and the second connecting frame tube 13 that are away from the mounting frame tube 11. In conjunction with the flipping frame tube 2 in the above embodiment, the first connecting end 21 can be connected to the first connecting frame tube 12 through the rotating mechanism 3, and the second connecting end 22 can be connected to the second connecting frame tube 13 through the locking mechanism 4. Thus, when the second connecting end 22 is separated from the second connecting frame tube 13 through the locking mechanism 4, the flipping frame tube 2 can rotate on the first connecting frame tube 12 with the first connecting end 21 as the center of rotation through the rotating mechanism 3 to open the opening on the support bracket 1. When the second connecting end 22 is connected to the second connecting frame tube 13 through the locking mechanism 4, the rotation of the flipping frame tube 2 on the first connecting frame tube 12 can be restricted to close the opening on the support bracket 1.

[0054] Furthermore, refer to Figure 3 As shown, in some embodiments, the rotating mechanism 3 includes: a first sliding seat 31, which is sleeved on the first connecting frame tube 12 and can slide on the first connecting frame tube 12; and a rotating shaft 32, which is rotatably mounted on the first sliding seat 31 and connected to the first connecting end 21, so that the flipping frame tube 2 can be flipped based on the first sliding seat 31 through the rotating shaft 32.

[0055] Specifically, in the technical solution adopted in this application, in order to enable the rotating mechanism 3 to provide a flipping mechanism to the flipping frame tube 2, in some embodiments, the rotating mechanism 3 may include: a first sliding seat 31 and a rotating shaft 32; the first sliding seat 31 is sleeved on the first connecting frame tube 12, and the rotating shaft 32 is rotatably disposed on the top of the first sliding seat 31, and the first connecting end 21 of the flipping frame tube 2 is connected to the rotating shaft 32, so that the flipping frame tube 2 can rotate on the first sliding seat 31 through the rotating shaft 32. Specifically, the flipping frame tube 2 flips outward based on the opening of the support bracket 1, thereby opening the opening of the support bracket 1, so that the user can smoothly enter the interior of the support bracket 1.

[0056] Furthermore, refer to Figure 3 As shown, in some embodiments, the rotating mechanism 3 further includes: a first locking pin 33, which is configured on the first sliding seat 31 in a plug-in connection manner; the first connecting frame tube 12 has a plurality of first locking holes 120 along its length direction, and the first locking pin 33 can be inserted into the corresponding first locking hole 120 to limit and fix the first sliding seat 31 on the first connecting frame tube 12.

[0057] Specifically, in the technical solution adopted in this application, in order to achieve an adjustable configuration of the first sliding seat 31 on the first connecting frame tube 12, the first sliding seat 31 can be slidably sleeved on the first connecting frame tube 12. In one embodiment, the first sliding seat 31 is provided with a first locking pin 33 in a plug-in connection manner, and the first connecting frame tube 12 has a plurality of first locking holes 120 arranged along its length direction. In use, after pulling out the first locking pin 33 from one of the first locking holes 120, the first sliding seat 31 can be slidably adjusted on the first connecting frame tube 12. When the first sliding seat 31 is displaced to the target position, the first locking pin 33 is inserted into the corresponding first locking hole 120, thereby limiting and fixing the first sliding seat 31 on the first connecting frame tube 12.

[0058] Furthermore, refer to Figure 2 and Figure 4 As shown, in some embodiments, the locking mechanism 4 includes: a second sliding seat 41, sleeved on the second connecting frame tube 13 and capable of sliding on the second connecting frame tube 13, the second sliding seat 41 having a locking groove 411, and a through hole 412 formed in the groove wall of the locking groove 411; a locking block 42, connected to the second connecting end 22, which can be driven into the locking groove 411 by rotating the flipping frame tube 2; and a third locking pin 44, for inserting into the through hole 412.

[0059] When the lock block 42 is displaced into the lock groove 411, the third lock pin 44 is inserted into the through hole 412 so as to limit and fix the lock block 42 in the lock groove 411.

[0060] Specifically, in the technical solution adopted in this application, in order to realize that the locking mechanism 4 can provide a locking and unlocking mechanism for controlling the flipping frame tube 2, in some embodiments, the locking mechanism 4 may include: a second sliding seat 41, a locking block 42, and a third locking pin 44 that cooperates with the second sliding seat 41 and the locking block 42; the second sliding seat 41 is sleeved on the second connecting frame tube 13, and a locking groove 411 is provided on the side of the second sliding seat 41 facing the opening of the support bracket 1, and a through hole 412 is opened on the groove wall of the locking groove 411. The locking block 42 is fixedly installed on the second connecting end 22 of the flipping frame tube 2. When the flipping frame tube 2 is rotated by the rotating mechanism 3, the locking block 42 can be driven into the locking groove 411, and the third locking pin 44 can be inserted into the through hole 412, so that the third locking pin 44 stands upright at the opening of the locking groove 411, thereby limiting and fixing the locking block 42 in the locking groove 411 on the second sliding seat 41. When it is necessary to rotate and flip the tube rack, simply pull the third locking pin 44 out of the through hole 412.

[0061] Furthermore, refer to Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, the locking mechanism 4 further includes: a second locking pin 43, which is configured on the second sliding seat 41 in a plug-in connection manner; the second connecting frame tube 13 has a plurality of second locking holes 130 along its length direction, and the second locking pin 43 can be inserted into the corresponding second locking hole 130 to limit and fix the second sliding seat 41 on the second connecting frame tube 13.

[0062] Specifically, in the technical solution adopted in this application, in order to adjustably configure the second sliding seat 41 on the second connecting frame tube 13, the second sliding seat 41 can be slidably sleeved on the second connecting frame tube 13. In one embodiment, the second sliding seat 41 is provided with a second locking pin 43 in a plug-in connection manner, and the second connecting frame tube 13 has several second locking holes 130 with different length directions of flue gas. In use, after pulling out the second locking pin 43 from one of the second locking holes 130, the second sliding seat 41 can be slidably adjusted on the second connecting frame tube 13. When the second sliding seat 41 is displaced to the target position, the second sliding seat is inserted into the corresponding second locking hole 130, thereby limiting and fixing the second sliding seat 41 on the second connecting frame tube 13.

[0063] Furthermore, refer to Figure 5 and Figure 6 As shown, in some embodiments, the first protective mechanism 5 includes: a first mounting base 51, sleeved on the tilting frame tube 2, with a first lead screw sleeve 511 extending in a first direction disposed on the first mounting base 51; a first lead screw 52, ​​threadedly installed in the first lead screw sleeve 511; and a second mounting base 53, slidably mounted on one side of the first mounting base 51 in the first direction, and connected to the end of the first lead screw 52 via a first bearing, with a second lead screw sleeve 531 disposed on the second mounting base 53. The second direction extends perpendicular to the first direction; the sliding sleeve 54 is slidably fitted onto the second mounting base 53 along the second direction; the second lead screw 55 is mounted on the sliding sleeve 54 via the second bearing and is threadedly installed in the second lead screw sleeve 531, and rotating the second lead screw 55 can drive the sliding sleeve 54 to slide on the second mounting base 53; the first back plate 56 is mounted on the side of the sliding sleeve 54 away from the first mounting base 51; the first support member 57 is mounted on the sliding sleeve 54 via the first back plate 56 and is used to support the user's waist and back.

[0064] Specifically, in the technical solution adopted in this application, the first mounting base 51 is fixed to the tilting frame tube 2 by a sleeve, and a first screw sleeve 511 is configured in the first mounting base 51. When the tilting frame tube 2 is closed at the opening of the bearing bracket 1, the first screw sleeve 511 extends toward the second protective mechanism 6, and a first screw member 52 is installed in the first screw sleeve 511 by a threaded engagement; the second mounting base 53 can be connected to one side of the first mounting base 51 by a first limiting sliding rod 58, based on the tilting mechanism. The rotation mechanism of the frame tube 2 is such that the second mounting seat 53 is located on the side of the first mounting seat 51 near the support bracket 1; the first lead screw 52 and the second mounting seat 53 are connected by the first bearing. When the first lead screw 52 is rotated to cooperate with the first lead screw sleeve 511, the second mounting seat 53 can slide based on the first mounting seat 51 by supporting the first lead screw 52. When the flip frame tube 2 is closed at the opening of the support bracket 1, the second mounting seat 53 can slide closer to or further away from the second protective mechanism 6, which is the first direction. In this embodiment, a second lead screw sleeve 531 extending along a second direction is disposed on the second mounting base 53. The second direction is the height direction of the waist protection device and is perpendicular to the first direction. A sliding sleeve 54 is sleeved on the second mounting base 53 and can slide along the second direction on the second mounting base 53. A second lead screw member 55 is rotatably disposed on the sliding sleeve 54 through a second bearing member, and the second lead screw member 55 is threadedly installed in the second lead screw sleeve 531. When the second lead screw member 55 is rotated to engage with the second lead screw sleeve 531, the sliding sleeve 54 can be slid based on the second mounting base 53 by supporting the second lead screw member 55, so as to adjust the position of the sliding sleeve 54 on the second mounting base 53 based on the second direction. A first support member 57 is mounted on the side of the sliding sleeve 54 away from the first mounting base 51 via the first back plate 56. One side of the first support member 57 adopts a flat surface that matches the first back plate 56, while the other side is provided with a first relief groove to adapt to the user's lower back, so that the user's lower back is more comfortable when it contacts the first support member 57 and provides more stable support.

[0065] Furthermore, refer to Figure 7 and Figure 8As shown, in some embodiments, the second protective mechanism 6 includes: a third mounting base 61, sleeved on the mounting bracket tube 11, with a third lead screw sleeve 611 disposed on the third mounting base 61, the third lead screw sleeve 611 extending in the second direction; a third lead screw 62, threadedly installed in the third lead screw sleeve 611; and a fourth mounting base 63, mounted on the third lead screw 62 via a third bearing, wherein rotating the third lead screw 62 can drive the fourth mounting base 63 to move along the second direction on the third mounting base 61, and a fourth lead screw sleeve is disposed on the fourth mounting base 63. 631, the fourth lead screw sleeve 631 extends in a first direction perpendicular to the second direction; the fourth lead screw member 64 is installed in the fourth lead screw sleeve 631 by a threaded engagement; the second back plate 65 is slidably installed on one side of the fourth mounting base 63 along the first direction and is connected to the end of the fourth lead screw member 64 through a fourth bearing member, and the second back plate 65 can be driven to move on the fourth mounting base 63 along the first direction by rotating the fourth lead screw member 64; the second support member 66 is installed on the side of the second back plate 65 away from the fourth mounting base 63 and is used to support the user's abdomen.

[0066] Specifically, in the technical solution adopted in this application, the third mounting base 61 is fixed to the mounting bracket tube 11 by a sleeve, and a third screw sleeve 611 is configured on the third mounting base 61. The third screw sleeve 611 extends toward the second direction, which is the height direction of the waist protection device. A third screw member 62 is installed in the third screw sleeve 611 by a threaded engagement. The end of the third screw member 62 is connected to the fourth mounting base 63 through a third bearing member. The fourth mounting base 63 can be connected to one side of the third mounting base 61 by a second limiting sliding rod 601. The fourth mounting base 63 slides along the second direction based on the third mounting base 61 through the second limiting sliding rod 601, so that the third screw member 62 can rotate in the third screw sleeve 611 based on the fourth mounting base 63. Thus, the support of the third screw member 62 can drive the fourth mounting base 63 to slide in the second direction. In this embodiment, a fourth lead screw sleeve 631 extending along a first direction is disposed on the fourth mounting base 63, and a fourth lead screw member 64 is installed in the fourth lead screw sleeve 631 by means of threaded engagement.
