[0002] The hip joint assisted walking device is a device for hip joint recovery. When used on patients after THR, it can effectively reduce the pain of patients during recovery exercises, relieve patients' negative emotions, and further promote the recovery of hip joint function.

[0003] In the existing technology, when patients use hip joint assisted walking devices, the continuous assistance provided by the device can greatly reduce the gravitational load borne by the hip joint. However, long-term reliance on this assistance can easily lead to dependence on the device, resulting in reduced demand for active muscle force and delayed recovery process. When the physiological structure of the hip joint recovers, patients lack independent weight-bearing training and find it difficult to quickly adapt to the unassisted state, resulting in problems such as unstable gait and abnormal gait, which hinders the rehabilitation effect and the recovery of daily living ability. For this reason, we propose a hip joint assisted walking device. Summary of the Invention

The design of the fixing belt 27 is to fix the positioning frame 5 at the thigh. The front side of the waist frame 1 is fixedly connected with a fixing belt 6. The design of the fixing belt 6 is to facilitate fixing the waist frame 1 to the patient's waist. The rear end of the waist frame 1 is provided with a starting switch 8. The design of the starting switch 8 is to unlock the oscillator 3 and put the power-assisted walking device in the on state. The rear end of the waist frame 1 is fixedly connected with a mounting seat 9. The design of the mounting seat 9 is to facilitate the installation of other internal structures. The interior of the mounting seat 9 is provided with a detection mechanism 10 for starting the power-assisted walking device. The front side of the waist frame 1 is fixedly connected with a backboard 18. The design of the backboard 18 is to facilitate supporting the patient's back.

[0018] The detection mechanism 10 includes a start button 1001 installed at the bottom end of the mounting seat 9. When the start button 1001 is pressed, the swing seat 2 will drive the swing arm 3, allowing the swing arm 3 to assist the moving patient. The mounting seat 9 is internally fixedly connected to a mounting column 1002. The mounting column 1002 is designed to facilitate the installation of a rotating piece 1003. The mounting column 1002 is internally rotatably connected to a rotating piece 1003. The rotating piece 1003 is designed to press the start button 1001 under the drive of the counterweight ball 1005 and the pull rope 1006.

[0019] The inner top of the mounting seat 9 is fixedly connected to a tilting chamber 1004, which is designed to facilitate the installation of a counterweight ball 1005. The inner part of the tilting chamber 1004 is slidably connected to a counterweight ball 1005, which is designed to pull the pulling rope 1006 when the tilting chamber 1004 tilts, thereby pulling one end of the rotating piece 1003, thereby pressing the other end of the rotating piece 1003 down.

[0020] A pulling rope 1006 is fixedly connected to the outside of the counterweight ball 1005 . The pulling rope 1006 is designed to connect the counterweight ball 1005 and the rotating piece 1003 . The bottom end of the pulling rope 1006 is rotatably connected to the inside of the rotating piece 1003 .

[0021] The inner bottom end of the mounting base 9 is fixedly connected with a support column 1007, which is designed to support a push spring 1008. A push spring 1008 is sleeved on the outer side of the support column 1007, which is designed to push the rotating piece 1003. A sliding groove 1009 is provided inside the rotating piece 1003. The sliding groove 1009 is designed to facilitate the sliding of the support column 1007. The outer side of the support column 1007 is slidably connected to the inside of the sliding groove 1009.

[0022] The interior of the mounting seat 9 is slidably connected with a connecting rod 11, which is designed to connect the pressing piece 12 and the card seat 13, and is also designed to facilitate the installation of the push spring 2 14 and the push piece 15. One end of the connecting rod 11 is fixedly connected to the pressing piece 12, and the pressing piece 12 itself is oval. The other end of the connecting rod 11 is fixedly connected to the card seat 13, and the card seat 13 is designed to engage with the positioning groove 16 to fix the pressing piece 12. The power-assisted walking device has two modes. The first mode is that when the start switch 8 is pressed, the power-assisted walking device It will be started normally. At this time, the patient is wearing a walking assist device, but the walking assist device does not assist the patient. If the patient tilts while walking, or the body leans forward, it means that the patient needs assistance. At this time, the counterweight ball 1005 in the tilt chamber 1004 will pull the pulling rope 1006 due to the tilt of the tilt chamber 1004, thereby driving one end of the rotating piece 1003, thereby pressing the other end of the rotating piece 1003. The rotating piece 1003 with the other end pressed down will squeeze the start button 1001. At this time, the start button 1001 will enable the patient to walk with assistance. The device normally assists the patient's lower limbs for a period of time. The second mode is when the power-assisted walking device is required to assist the patient normally. Pull the pulling ring 17 by hand to pull the holder 13 out of the positioning groove 16. At this time, rotate the holder 13 again, thereby driving the connecting rod 11 and the pressing piece 12 to rotate. After the holder 13 is rotated to ninety degrees, it is engaged with the inside of the positioning groove 16 again. At this time, the pressing piece 12 will squeeze the rotating piece 1003, thereby pressing the start button 1001. At this time, the power-assisted walking device will continue to assist the patient's thigh. When the holder When 13 is engaged with the positioning groove 16, the push spring 14 will push the push piece 15, thereby driving the connecting rod 11, and the connecting rod 11 drives the holder 13, so that the holder 13 is firmly engaged with the positioning groove 16. By controlling whether the power-assisted walking device provides assistance according to the patient's walking situation, the patient's dependence on the hip joint power-assisted walking device is reduced, which can stimulate the muscles to actively exert force, shorten the rehabilitation process, and adapt to the unassisted state more quickly to avoid problems such as unstable walking and abnormal gait after recovery, thereby improving the rehabilitation effect and the recovery of daily living ability.

[0023] Example 2 In the second embodiment, other structures remain unchanged. The difference from the first embodiment is that a push spring 2 14 is provided on the outer side of the connecting rod 11. The push spring 2 14 is designed to push the push piece 15, thereby pushing the connecting rod 11. One end of the push spring 2 14 is fixedly connected to the push piece 15. The push piece 15 is designed to push the connecting rod 11 under the push of the push spring 2 14. The inner side of the push piece 15 is slidably connected to the outer side of the connecting rod 11.

[0024] A positioning groove 16 is provided on the outer side of the mounting base 9. The positioning groove 16 is designed to facilitate the engagement of the card base 13. The outer side of the card base 13 is slidably connected to the inside of the positioning groove 16. A pulling ring 17 is fixedly connected to the outer side of the card base 13. The pulling ring 17 is designed to facilitate pulling the card base 13 to separate the card base 13 from the positioning groove 16.
