[0052] See also Figure 1 and Figure 2 The present embodiment provides a post-hip replacement car seat, which includes: a seat body 100, a seat chassis 200 and a motion component 300, wherein the motion component 300 is connected to the seat body 100 and the seat chassis 200, and the motion component 300 is used to adjust the posture of the seat body 100 so that the seat body 100 has a first state facing the door 430 and a low posture, a second state facing the front glass window 410 and a high posture, and a third state with a transfer and facing the door 430; wherein the motion component 300 includes: an X-axis moving mechanism 310, a rotating mechanism 320 and a lifting mechanism 330, an X-axis moving mechanism 310 is arranged on the seat chassis 200, and the X-axis moving mechanism 310 is drivingly connected to the seat body 100, and the X-axis moving mechanism 310 is used to drive the seat body 100 to move forward and backward along the X direction, a rotating mechanism 320 is arranged on the X-axis moving mechanism 310, and the rotating mechanism 320 is drivingly connected to the seat body 100, and the rotating mechanism 320 is used to drive the seat body 100 to rotate, and a lifting mechanism 330 is arranged on the rotating mechanism 320, and the seat body 100 is provided on the lifting mechanism 330, and the lifting mechanism 330 is used to drive the seat body 100 to move up and down.
[0053] In the prior art, during the use of traditional car seats, patients who have undergone hip replacement surgery are required to try their best to move to the center of the seat. However, patients who have undergone surgery are often physically exhausted, or have pain or weak legs. Therefore, patients who have undergone hip replacement surgery have difficulty getting in and out of the car.
[0054] In this embodiment, the motion component 300 is disposed on the seat chassis 200. The motion component 300 can drive the seat body 100 to adjust the posture of the seat body 100, thereby assisting patients after hip replacement surgery to get on or off the vehicle to solve the problem of difficulty in getting on and off the vehicle.
[0055] See also Figure 3 and Figure 4 , the first state of the seat body 100 can be used for the patient to get on the vehicle. For example, when getting on the vehicle, the motion component 300 can drive the seat body 100 to move forward for a distance, and then the motion component 300 can drive the seat body 100 to rotate so that the seat body 100 faces the vehicle door 430. According to the height of the patient, the motion component 300 can drive the seat body 100 to rise and fall, so that the patient can directly sit sideways on the seat body 100 outside the vehicle. For example, the motion component 300 can drive the seat body 100 to descend a certain height, and then the patient can directly sit sideways on the seat body 100 outside the vehicle, so that the patient does not need to move to the inside of the vehicle 400 and then sit down.
[0056] The second state of the seat body 100 can be used when the patient is sitting in the car. For example, after the patient gets in the car, that is, after the patient sits on the seat body 100 outside the car, the motion component 300 can drive the seat body 100 to rise, together with the patient, and then the motion component 300 can drive the seat body 100 to rotate so that the seat body 100 faces the front glass window 410, and then the motion component 300 can drive the seat body 100 to move backwards, and after moving backwards, the seat body 100 can be tilted back as much as possible to ensure that the lower limbs have sufficient space for extension to avoid the hip joint flexion angle exceeding 90 degrees.
[0057] The third state of the seat body 100 can be used for the patient to get off the vehicle. For example, when the patient needs to get off the vehicle, the motion assembly 300 can drive the seat body 100 to move forward, and then the motion assembly 300 can drive the seat body 100 to rotate so that the seat body 100 faces the vehicle door 430, and then the motion assembly 300 can drive the seat body 100 to descend to a certain height, and then the patient can directly get off the seat to the ground, so that the patient does not need to move from the seat to the vehicle and then get off the vehicle.
[0058] In this embodiment, the patient should try to avoid internal rotation, abduction or excessive flexion of the hip joint when getting on and off the vehicle. For example, when getting on the vehicle, the patient can face the seat with his back, use the upper limbs to support the body and slowly sit down, while keeping the lower limb on the operated side straight forward, and after getting into the seat, he can then enter the vehicle by synchronously rotating both legs to avoid joint instability caused by single-leg rotation.
[0059] Among them, see Figure 5 The motion assembly 300 includes: an X-axis moving mechanism 310, a rotating mechanism 320, and a lifting mechanism 330. The X-axis moving mechanism 310 is used to drive the seat body 100 to move forward and backward, the rotating mechanism 320 is used to drive the seat body 100 to rotate, and the lifting mechanism 330 is used to drive the seat body 100 to move up and down. Through the coordination between the X-axis moving mechanism 310, the rotating mechanism 320, and the lifting mechanism 330, the first state, the second state, and the third state of the seat body 100 are realized, thereby solving the problem of difficulty in getting on and off the vehicle for patients. For example, the lifting mechanism 330 can drive the seat body 100 to rise to a certain height, so that the height of the seat body 100 is higher than the length of the patient's calf.
[0060] Therefore, the present application adjusts the posture of the seat body 100 through the motion component 300 to assist patients who have undergone hip replacement surgery to use the car seat and solve the problem of patients having difficulty getting in and out of the car.
[0061] Specifically, see Figure 1 and Figure 3When the seat body 100 is in the first state, the X-axis moving mechanism 310 drives the seat body 100 to move forward so that the seat body 100 is exposed on the vehicle body side 420, and the lifting mechanism 330 drives the seat body 100 to descend and the rotating mechanism 320 drives the seat body 100 to rotate, so that the seat body 100 faces outside the vehicle and descends for sitting.
[0062] In this embodiment, the first state can be used for the patient to get on the vehicle. At this time, the seat body 100 is driven by the X-axis moving mechanism 310 to move forward a certain distance. Thereafter, the seat body 100 is driven by the rotating mechanism 320 to face the vehicle door 430 and the seat body 100 is exposed at the side wall 420 of the vehicle body to avoid the vehicle body interfering with the seat body 100. The lifting mechanism 330 drives the seat body 100 to descend, which can lower the height of the seat body 100. The patient can turn his back to the seat, use his upper limbs to support the body and sit down slowly, while keeping the lower limb on the operated side stretched forward. After entering the seat, the rotating mechanism 320 can be used to drive the seat body 100 and the patient to rotate together to enter the vehicle, thereby avoiding the problem of joint instability caused by single-leg rotation.
[0063] Specifically, see Figure 2 and Figure 4 When the seat body 100 is in the second state, the lifting mechanism 330 drives the seat body 100 to rise, and the rotating mechanism 320 drives the seat body 100 to rotate and move toward the front side of the vehicle body, and the X-axis moving mechanism 310 drives the seat body 100 to move backward, so that the seat body 100 is adjusted into the vehicle body to avoid excessive flexion of the hip joint.
[0064] In this embodiment, the second state can be used when the patient is sitting in the car. When the patient sits down with his back to the seat, the lifting mechanism 330 can drive the seat body 100 to rise to a certain height to avoid interference between the body and the patient's lower limbs, and can rotate into the car during subsequent rotation. Then, the rotating mechanism 320 can drive the seat body 100 to rotate, and the rotating mechanism 320 drives the seat body 100 and the patient to rotate into the car together. After the rotation, the X-axis moving mechanism 310 can drive the seat body 100 to move backward, and the seat body 100 can be tilted back appropriately to ensure that the lower limbs have sufficient stretching space to avoid the hip joint flexion angle exceeding 90 degrees.
[0065] Specifically, see Figure 1 and Figure 4 When the seat body 100 is in the third state, the X-axis moving mechanism 310 drives the seat body 100 to move forward so that the seat body 100 is exposed to the vehicle body side 420, and the rotating mechanism 320 drives the seat body 100 to rotate so that the seat body 100 faces the outside of the vehicle, and the lifting mechanism 330 drives the seat body 100 to descend so that the seat body 100 descends to wait for the seat to be lifted up.
[0066] In this embodiment, the third state can be used for the patient to get off the vehicle. In the third state, the patient can use the upper limbs to support the body to slowly get up, and then directly get down from the seat body 100 to the ground. For example, the X-axis moving mechanism 310 drives the seat body 100 to move forward for a distance, and then the rotating mechanism 320 drives the seat body 100 to rotate so that the seat body 100 faces outside the vehicle, that is, the seat body 100 drives the patient toward the door 430, and then the lifting mechanism 330 drives the seat body 100 to descend a certain height, and the patient can use the upper limbs to support the body to slowly get up from the seat body 100, and then get down from the seat body 100 to the ground.
[0067] See also Figure 5 The X-axis moving mechanism 310 includes: a first driving source 311, a first sliding group 312 and a first moving base 315. The first driving source 311 is arranged on the seat chassis 200. The first driving source 311 is used to drive the seat body 100 to move along the X direction. The first sliding group 312 is connected to the first driving source 311. The first sliding group 312 is used to realize the first driving source 311 driving the seat body 100 to slide. The first moving base 315 is connected to the first sliding group 312 and the seat body 100. The first moving base 315 is used to install the seat body 100.
[0068] In this embodiment, the seat body 100 is mounted on the first movable base 315, the first driving source 311 can drive the first sliding group 312 to move along the X direction, and the first sliding group 312 can drive the first movable base 315 to move in a directional manner, thereby enabling the first driving source 311 to drive the seat body 100 to move in a directional manner along the X direction. For example, the first driving source 311 can use a ball screw, which can include a screw, a ball, and a nut. When the screw rotates, the ball rolls in the raceway between the screw and the nut, converting the rotational motion of the screw into the linear motion of the nut, thereby driving the first sliding group 312 to move in a directional manner along the X direction.
[0069] Specifically, see Figure 6 The first sliding group 312 includes: a group of first sliding rails 313 and a first slider 314, the first sliding rail 313 is arranged on the seat chassis 200 along the X direction, the first slider 314 is slidably connected to the first sliding rail 313, and the first slider 314 is connected to the first driving source 311 and the first movable base 315.
[0070] In this embodiment, the first slide rail 313 is slidably connected to the first slider 314 , and the first driving source 311 can drive the first slider 314 to move along the first slide rail 313 in a directional manner to maintain the stability and accuracy of the linear motion.
[0071] Specifically, see Figure 7The rotating mechanism 320 includes: a second rotating base 321, a second driving source 322 and a second rotating shaft 323. The second rotating base 321 is arranged on the first movable base 315 of the X-axis moving mechanism 310, the second driving source 322 is arranged on the second rotating base 321, the second rotating shaft 323 is transmission-connected with the second driving source 322, and the second rotating shaft 323 is connected to the lifting mechanism 330.
[0072] In this embodiment, the second rotating base 321 is installed on the first moving base, that is, the X-axis moving mechanism 310 can drive the rotating mechanism 320 to move in a directional manner along the X direction, thereby driving the movement together. The second rotating base 321 is provided with a second driving source 322, and the second driving source 322 is drivingly connected to the second rotating shaft 323, and the second rotating shaft 323 is connected to the lifting mechanism 330. The second driving source 322 can drive the second rotating shaft 323 to rotate, thereby causing the lifting mechanism 330 to rotate together with the seat body 100. The structure is simple and easy to implement. For example, the second driving source 322 can be a rotating motor, that is, the rotating motor can drive the second rotating shaft 323 to rotate, so as to realize driving the seat body 100 to rotate together.
[0073] Specifically, see Figure 8 The second rotating shaft 323 includes: a rotating shaft body 324 and a group of axial shaft keys 325. The rotating shaft body 324 is connected to the second driving source 322 and the lifting mechanism 330. The axial shaft key 325 is arranged on the rotating shaft body 324. The axial shaft key 325 is embedded in the lifting mechanism 330 and is slidably connected to the lifting mechanism 330. The axial shaft key 325 is used to drive the lifting mechanism 330 to rotate.
[0074] In this embodiment, the rotating shaft body 324 is connected to the lifting mechanism 330 through the axial shaft key 325. When the second driving source 322 drives the rotating shaft body 324 to rotate, the rotating shaft body 324 can transmit torque with the help of the axial shaft key 325, thereby driving the lifting mechanism 330 to rotate together, and when the lifting mechanism 330 is lifted and moved, the lifting mechanism 330 can slide in a directional manner along the axial shaft key 325. The axial shaft key 325 also has the function of maintaining the stability and accuracy of the linear motion.
[0075] Specifically, see Figure 7The lifting mechanism 330 includes: a third lifting base 331, a third driving source 332, a driving gear 333 and a third lifting tube 334. The third lifting base 331 is arranged on the second rotating base 321 of the rotating mechanism 320, the third driving source 332 is arranged on the third lifting base 331, the driving gear 333 is transmission-connected with the third driving source 332, a rack ring 337 is provided on the third lifting tube 334, the rack ring 337 is transmission-connected with the driving gear 333, and the third lifting tube 334 is connected to the second rotating shaft 323 of the rotating mechanism 320 and the seat body 100.
[0076] In this embodiment, the third lifting base 331 can be fixed on the second rotating base 321, wherein the third lifting base 331 is installed with a third driving source 332, a driving gear 333 and a third lifting tube 334, the third driving source 332 is drivingly connected to the driving gear 333, and the third lifting tube 334 is provided with a rack ring 337, which is meshed and transmission-connected with the driving gear 333, that is, when the third driving source 332 drives the driving gear 333 to rotate, the driving gear 333 can drive the third lifting tube 334 to move up and down, so as to realize the lifting and moving of the seat body 100. For example, the third driving source 332 can be a rotating motor, that is, the rotating motor can drive the driving gear 333 to rotate, and the driving gear 333 can drive the third lifting tube 334 to move up and down, so as to realize the lifting and moving of the seat body 100.
[0077] Specifically, see Fig. 9 The third lifting tube 334 includes: a lifting tube body 335 and an axial key groove 336. The lifting tube body 335 is provided with a rack ring. The axial key groove 336 is opened on the inner wall of the lifting tube body 335. The axial key groove 336 is used to cooperate and connect with the axial shaft key 325 of the second rotating shaft 323.
[0078] In this embodiment, the inner wall of the lifting tube body 335 is provided with an axial keyway 336 that cooperates with the axial shaft key 325, wherein the axial shaft key 325 is slidably connected to the axial keyway 336. When the third driving source 332 drives the third lifting tube 334 to move up and down, the axial keyway 336 can move in a directional manner along the axial shaft key 325. When the second driving source 322 drives the second rotating shaft 323 to rotate, at this time, the axial shaft key 325 abuts against the axial keyway 336, and the second rotating shaft 323 can drive the lifting tube body 335 to rotate, and the rack ring slides horizontally along the driving gear 333, that is, when the rack ring rotates, the driving gear 333 can remain stationary.
[0079] In this embodiment, the chair body 100 includes a backrest and a backrest rotation mechanism 320, and the backrest rotation mechanism 320 is used to drive the backrest to rotate forward or tilt backward, wherein the chair body 100 may also include a locking mechanism, which is connected to the backrest, and the locking mechanism is used to stop the backrest from rotating to prevent the backrest from tilting forward at an angle lower than 90°.
