[0002] In the related art, transferring elderly people with limited mobility between beds, chairs, wheelchairs, etc. is a huge project, sometimes requiring two or three people to help at the same time, which requires a lot of manpower and can easily cause secondary injuries during the movement process. However, there are not many people in general families who can take care of the elderly, especially those living alone. Therefore, the needs of caring for elderly people with limited mobility cannot be met. In addition, a more traditional locking mechanism is usually used for manual locking to complete the transition of the nursing machine from the wheelchair to the bed. However, the traditional locking mechanism makes the operation more complicated and creates certain obstacles for elderly people with limited mobility. In particular, the complex locking mechanism is very troublesome if the elderly person is unable to operate it due to physical reasons. Moreover, the nursing machines commonly found in the domestic market have single functions and are inconvenient to use, and cannot meet the various needs of the elderly. Summary of the Invention

[0043] Below, refer to Figure 1 A self-locking mechanism according to an embodiment of the present invention is described.

[0044] like Figure 1 As shown, the self-locking mechanism according to an embodiment of the present invention includes:

[0045] The fixing component 100 is fixedly arranged;

[0046] The rotating mechanism 200 includes a self-locking rod 210 and a first rotating component 220. The self-locking rod 210 is rotatably connected to the fixed component 100. One end of the self-locking rod 210 is connected to the first rotating component 220. The other end of the self-locking rod 210 can be forced to rotate toward the bottom of the fixed component 100 and enable the first rotating component 220 to be engaged with the external connecting piece.

[0047] By setting a self-locking rod 210 and rotatably connecting the self-locking rod 210 to the fixed component 100, the self-locking rod 210 can rotate around the fixed component 200 as the axis, and a first rotating component 220 is set at one end of the self-locking rod 210. When the other end of the self-locking rod 210 is rotated toward the bottom of the fixed component 100 by an external force, the first rotating component 220 will rotate toward the top of the fixed component 100 and engage with the external connecting member. Therefore, the self-locking mechanism can be engaged with the external connecting member without manual operation, which is convenient and quick. In addition, the self-locking mechanism has a simple structure, is easy to implement, and is easy to disassemble and assemble.

[0048] It is understandable that if Figure 2 As shown, the first rotating assembly 220 includes a first clamping member 221 and a second clamping member 222. The first clamping member 221 and the second clamping member 222 form a clamping slot 223, which is clamped to the external connecting member. The provision of the clamping slot 223 facilitates the clamping connection with the external connecting member and has a simple structure and is easy to implement.

[0049] Specifically, if Figure 3 As shown, the first clamping member 221 includes a second sleeve 2211 and a first clamping block 2212, and the second clamping member 222 includes a connecting block 2221 and a second clamping block 2222. The first clamping block 2212 is detachably connected to the second sleeve 2211, one end of the self-locking rod 210 is detachably connected to the second sleeve 2211, the connecting block 2221 is detachably connected to the second sleeve 2211, and the connecting block 2221 is detachably connected to the second clamping block 2222. The structure is simple and easy to assemble and disassemble.

[0050] Furthermore, if Figure 3 As shown, the second sleeve 2211 is provided with a first through hole 2211a and a first connecting hole 2211b. One end of the self-locking rod 210 is inserted into one end of the first through hole 2211a and is detachably connected to the second sleeve 2211. The connecting block 2221 is inserted into the other end of the first through hole 2211a and is detachably connected to the second sleeve 2211. The first clamping block 2212 is inserted into the first connecting hole 2211b and is detachably connected to the second sleeve 2211. The connecting block 2221 is provided with a second connecting hole 2221a. The second clamping block 2222 is inserted into the second connecting hole 2221a and is detachably connected to the connecting block 2221. The first clamping block 2212 and the second clamping block 2222 further increase the depth of the card slot 223, making it easier to clamp the external connector when docking with the external connector. The structure is simple and convenient for assembly and disassembly.

[0051] It is understandable that if Figure 2 As shown, the rotating mechanism 200 further includes a second rotating assembly 230, which is connected to the other end of the self-locking rod 210. The second rotating assembly 230 can increase the force-bearing area of the other end of the self-locking rod 210, ensuring that the self-locking mechanism can sense the force in time and operate stably.

[0052] It is understandable that if Figure 4 and Figure 5 As shown, the second rotating assembly 230 includes a pressure-bearing member 231 and a connecting assembly 232. The pressure-bearing member 231 is detachably connected to the connecting assembly 232, and the connecting assembly 232 is detachably connected to the other end of the self-locking rod 210. The structure is simple and easy to assemble and disassemble. It is understandable that, as Figure 4As shown, the pressure member 231 is rectangular, which is used to expand the contact area and ensure that the self-locking mechanism can receive force in a timely manner and operate stably. It is understood that the pressure member 231 can also be square, circular, or elliptical. To save material, the pressure member 231 can also be in a grid shape, with the mesh of the grid being rectangular, square, circular, or elliptical. For long-term durability, the pressure member 231 is made of acrylic.

[0053] It is understandable that if Figure 5 As shown, the connecting assembly 232 includes a first sleeve 2321, a connecting rod 2322, and a connecting sleeve 2323. The first sleeve 2321 is detachably connected to the other end of the self-locking rod 210, the connecting rod 2322 is detachably connected to the first sleeve 2321, the connecting sleeve 2323 is sleeved on the connecting rod 2322, and the connecting sleeve 2323 is detachably connected to the pressure-bearing member 231. The structure is simple and easy to assemble and disassemble.

[0054] Specifically, if Figure 4 and Figure 5 As shown, the first sleeve 2321 is provided with a second through hole 2321a and a third connecting hole 2321b. The other end of the self-locking rod 210 is inserted into the second through hole 2321a and is removably connected to the first sleeve 2321. The connecting rod 2322 is inserted into the third connecting hole 2321b and is removably connected to the first sleeve 2321. The connecting sleeve 2323 is provided with multiple mounting holes 2323a. Screws are inserted through the mounting holes 2323a to removably connect the connecting sleeve 2323 to the pressure-bearing member 231. The connecting assembly 232 is convenient for disassembly and installation, and it is also easy to replace defective parts. Furthermore, screws are inserted through the mounting holes 2323a to thread the connecting sleeve 2323 to the pressure-bearing member 231. The connection is stable and facilitates the rotation of the pressure-bearing member 231. The threaded connection also facilitates disassembly and assembly.

[0055] It is understandable that if Figure 6 and Figure 7 As shown, the fixing assembly 100 includes a fixing sleeve 110, a fixing rod 120, and a bracket 130. The fixing sleeve 110 is detachably connected to one end of the fixing rod 120, and the other end of the fixing rod 120 is detachably connected to the bracket 130. Specifically, the fixing sleeve 110 is provided with a third through hole 111 and a fourth connecting hole 112. The self-locking rod 210 is inserted into the third through hole 111 and is detachably connected to the fixing sleeve 110. One end of the fixing rod 120 is inserted into the fourth connecting hole 112 and is rotatably connected to the fixing sleeve 110. The self-locking rod 210 is inserted into the fixing sleeve 110 and the fixing sleeve 110 is rotatable, so that the self-locking rod 210 and the fixing sleeve 110 can rotate about the fixing rod 120. This structure is flexible and easy to implement. It is understandable that there are two fixing rods 120, one on each side of the fixing sleeve 110.

[0056] Below, refer to Figure 8 A care machine according to an embodiment of the present invention is described.

[0057] like Figure 8 As shown, the nursing machine according to an embodiment of the present invention includes:

[0058] Bed 300;

[0059] Like the self-locking mechanism mentioned above, the self-locking mechanism is connected to the bed 300;

[0060] Wheelchair 400, wheelchair 400 includes a base 410 and a supporting assembly 420, the external connecting part is the base 410, the base 410 is provided with a plurality of electric push rod devices 411, one end of the electric push rod device 411 is fixedly set on the base 410, and the other end of the electric push rod device 411 is connected to the supporting assembly 420, and the supporting assembly 420 can make the rotating mechanism 200 rotate and engage with the base 410.

[0061] By adopting a self-locking mechanism and using a coordinated bed 300 and wheelchair 400, when the wheelchair 400 needs to be combined with the bed 300, first, the electric push rod device 411 adjusts the support assembly 420 to switch the wheelchair 400 from a standing or sitting position to a lying position, and then the wheelchair 400 is brought close to the bed 300 for connection. Finally, in the process of the wheelchair 400 approaching the bed 300, the support assembly 420 causes the first rotating assembly 220 and the second rotating assembly 230 in the self-locking mechanism to rotate around the fixed assembly 100. After the first rotating assembly 220 rotates and engages with the base 410, the wheelchair 400 and the bed 300 can be automatically connected. At this time, before the wheelchair 400 is released from the lying position and the pressure exerted by the wheelchair 400 on the self-locking structure disappears, the self-locking structure will always keep the wheelchair 400 and the bed 300 locked, with good stability and high safety. When the wheelchair 400 needs to be separated from the bed 300, the wheelchair 400 only needs to be moved away from the bed 300, and the self-locking mechanism can quickly separate the wheelchair 400 from the bed 300. The electric push rod device 411 can then be used to adjust the wheelchair 400 to a sitting or standing position as needed. The entire operation is convenient and fast, and the overall structure of the nursing machine is stable and has no shaking, and is safe and reliable. Therefore, the nursing machine can assist the elderly to complete the docking of the wheelchair 400 with the bed 300, and can also assist the elderly to independently complete basic actions required for daily life such as changing from lying to sitting, from sitting to standing, etc., so that people with limited mobility can regain the ability to live independently, and it has diverse functions and is easy to operate.

[0062] It is understandable that if Figure 8 As shown, the bed 300 is provided with a groove 310, and the self-locking mechanism is arranged in the groove 310, and the wheelchair 400 is engaged with the bed 300 through the groove 310. The arrangement of the groove 310 makes it easy to engage the bed 300 and the wheelchair 400, and can make the overall structure of the nursing machine more stable.

[0063] It is understandable that if Figure 9 As shown, the support assembly 420 includes a back pad 421, a first stopper 422, and a second stopper 423. The first stopper 422 is used to push the pressure-bearing member 231 when the wheelchair 400 is unfastened, and the second stopper 423 is used to abut the pressure-bearing member 231 when the wheelchair 400 is engaged. The back pad 421 is used to cooperate with the first stopper 422 to push the pressure-bearing member 231 or the second stopper 423 to abut the pressure-bearing member 231. The base 410 includes a third latch 412, which is used to engage with the latch slot 223. The structure is simple and easy to implement.

[0064] It is understandable that if Figure 9 As shown, the first stopper 422 and the second stopper 423 are located at the bottom of the back pad 421 and abut against the back pad 421, and the third latch 412 is located at the bottom of the back pad 421 and outside the base 410. The first stopper 422 and the second stopper 423 are located at the bottom of the back pad 421 and abut against the back pad 421, allowing the three to cooperate smoothly and be firmly connected. When engaged, the position of the third latch 412 is precisely sufficient to engage the first rotating assembly 220, further facilitating disassembly and installation.

[0065] Specifically, if Figure 9 and Figure 10 As shown, the wheelchair 400 is arranged from the smallest to the largest distance from the bed 300 when connected, and are arranged in order of the first stopper 422, the second stopper 423, and the third stopper 412. By providing the first stopper 422, the second stopper 423, and the third stopper 412, when connected, the back pad 421 pushes the second rotating assembly 230 to rotate about the fixed assembly 100 at the bottom of the fixed assembly 100, thereby driving the first rotating assembly 220 to engage with the third stopper 412. The second stopper 423 can resist the second rotating assembly 230, acting as a thrust. When separated, the first stopper 422 pushes the second rotating assembly 230 to rotate about the fixed assembly 100 at the top of the fixed assembly 100, causing the first rotating assembly 220 to separate from the third stopper 412. The back pad 421 assists in this process. The entire process does not require manual operation and has a simple structure, making it convenient and quick.

[0066] It is understandable that if Figure 8 and Figure 9As shown, there are two electric push rods 411, and the support assembly 420 also includes a seat cushion 424 and a fixing member. One end of one electric push rod 411 is detachably connected to a second stopper 423 located at the bottom of the back cushion 421, while one end of the other electric push rod 411 is detachably connected to a fixing member located at the bottom of the seat cushion 424. By manipulating the extension and retraction of the electric push rods 411, the wheelchair 400 can be adjusted between sitting, lying, and standing positions, thereby assisting the user in completing basic functions such as travel, changing postures, and transferring between different devices. It is understood that the support assembly 420 also includes foot pads 425 for protecting the calves.

[0067] As will be appreciated, four pulleys 413 are provided at the bottom of the base 410. The base 410 is also equipped with two drive motors 414. These drive motors 414 are located at the bottom of the back pad 421 and drive the two pulleys 413 on the side closest to the back pad 421. The two pulleys 413 further away from the back pad 421 are universal pulleys. This motor-driven operation facilitates operation. Furthermore, the two pulleys 413 closer to the back pad 421 are larger than the two further away from the back pad 421, making driving more labor-efficient.

[0068] It is understandable that if Figure 8 As shown, the length of the pressure member 231 is smaller than the width of the wheelchair 400. The length of the pressure member 231 along the width direction of the wheelchair 400 is smaller than the width of the wheelchair 400, which facilitates the rotation of the rotating mechanism 200 and the engagement of the bed 300 with the wheelchair 400.

[0069] like Figure 8 and Figure 10As shown, during operation, the wheelchair 400 is first positioned outside the bed 300 from a standing or sitting position to a lying position. The side of the wheelchair 400 containing the back cushion 421 is then positioned to preferentially enter the groove 310 of the bed, and the wheelchair 400 begins docking with the bed 300. Once the back cushion 421 of the wheelchair 400 contacts the pressure member 231, the back cushion 421 and the second stopper 423 continuously push against the pressure member 231 during the engagement process. This movement of the pressure member 231 causes the self-locking lever 210 and the first rotating assembly 220, which is secured to one end of the self-locking lever 210, to rotate about the fixed rod 120. When the back cushion 421 of the wheelchair 400 contacts the bed 300, the locking groove 223 of the first rotating assembly 220 pivots to the position of the third locking member 412 on the wheelchair's base 410, locking the third locking member 412 in place. At the same time, the second stopper 423 abuts against the pressure-bearing member 231. The second stopper 423 and the third clamping member 412 cooperate with each other to respectively restrict the movement of the pressure-bearing member 231 and the first rotating assembly 220 when the bed 300 and the wheelchair 400 are docked, so that the rotating mechanism 200 cannot rotate freely when the self-locking is completed. At the same time, the rotating mechanism 200 also firmly clamps the third clamping member 412 of the base 410 of the wheelchair 400, achieving the self-locking purpose and completing the reset and self-locking of the wheelchair 400.

[0070] It is understandable that if Figure 8 As shown, the bed 300 includes a bed frame 320 at the bottom, and the nursing machine also includes a crutch 500, which is placed in the bed frame 320. The crutch 500 is placed at the bottom of the bed 300, which can effectively save space. In addition, when it is necessary to stand up, the crutch 500 can be directly taken out from the bottom of the bed 300, which is convenient to operate.
