Description

Technical Field

[0001] This invention relates to the field of displacement device technology, and specifically to a multi-scenario intelligent displacement device for the elderly. Background Technology

[0002] With the increasing aging of society, the care of disabled or semi-disabled elderly people is becoming increasingly prominent. Among these challenges, safely and effortlessly assisting the elderly to move from their beds to wheelchairs, sofas, commodes, or other locations is one of the most common and labor-intensive aspects of daily care. Assistive mobility devices are important medical devices designed to address this problem.

[0003] Currently, mainstream elderly mobility aids on the market typically include a chassis with casters, a support column, a lifting mechanism, and a boom or sling to support the user. Their operation generally involves the caregiver pushing the mobility aid to the bedside, then pushing the entire or most of the chassis structure under the bed to bring the support column as close to the user's body as possible. The lifting mechanism then lifts the user in the sling for further movement. This design relies on the space under the bed to provide sufficient stabilizing torque to prevent tipping over due to a forward shift in the center of gravity when lifting the user.

[0004] Because of the current popular bed designs such as box beds, floor beds, and storage beds, the space under the bed frame is often closed or nearly closed, leaving no room for the transfer device chassis to extend. Therefore, the existing design principle of "must extend under the bed" has many inherent defects, which seriously limits its application scenarios and user experience.

[0005] To address the aforementioned issues, there is an urgent need in this field for a new type of elderly mobility aid that can completely eliminate reliance on the space under the bed or other furniture, achieving true "ready to use immediately upon contact with the bed and applicable to multiple scenarios," while ensuring safety, stability, and efficiency during operation.

[0030] The tire mechanism 30 includes a drive wheel 31 and a driven wheel 32.

[0031] The drive wheel 31 is located at the bottom center of the U-shaped chassis 10 and is used to drive the multi-scenario intelligent elderly assistive relocation device 1 to move.

[0032] Driven wheel 32 is located at the bottom of the end of the U-shaped arm to support the movement of the multi-scenario intelligent elderly assistive relocation device 1.

[0033] Figure 2 This is a schematic diagram of the U-shaped chassis of the multi-scenario intelligent elderly-assisting relocation device in an embodiment of the present invention.

[0034] like Figure 2 As shown, the U-shaped chassis 10 includes a left chassis 14, a right chassis 12, a slide rail 11, a slider 15, and a battery 16.

[0035] The left chassis 14 and the right chassis 12 are respectively provided with two set screw holes at the ends of the U-shaped arms. The driven wheel 32 is connected to the U-shaped chassis 10 through the set screws to support the multi-scenario intelligent elderly assistive relocation device 1 and assist the multi-scenario intelligent elderly assistive relocation device 1 in turning.

[0036] The left chassis 14 is provided with a strip-shaped groove and a set screw mounting hole, and the right chassis 12 is provided with a strip-shaped protrusion that matches the strip-shaped groove. By inserting the strip-shaped protrusion into the strip-shaped groove and tightening the set screw into the set screw mounting hole, the left chassis 14 and the right chassis 12 are fixed.

[0037] Both the left chassis 14 and the right chassis 12 have integrated racks on their U-shaped arms. The ends of the left chassis 14 and the right chassis 12 are equipped with limit blocks to prevent the double-sided lifting mechanism 40 from detaching beyond the limit.

[0038] The bottom of the left chassis 14 also houses the battery 16, and the bottom of the right chassis 12 also has a large square space for installing the lithium battery 16. The power cable of the lithium battery 16 enters the central follow-up control box 70 through the cable channel at the bottom of the U-shaped arm of the right chassis 12 to power the PCB board. The power cable uses an XT60 interface, which meets the power supply safety standard.

[0039] The slide rail 11 is connected to the double-sided lifting mechanism 40 to support the double-sided lifting mechanism 40 and prevent displacement and deformation.

[0040] The slider 15 is mounted on the slide rail 11 and is used to guide the forward and backward movement of the dual-sided lifting mechanism 40.

[0041] The dual-sided lifting mechanism 40 is mounted on the guide rail via the slider 15 and is used to drive the upper mechanism such as the seat plate 33 to rise and fall.

[0042] Figure 3 This is a schematic diagram of the structure of the dual-side lifting mechanism of the multi-scenario intelligent elderly-assisting relocation device in an embodiment of the present invention.

[0043] like Figure 3 As shown, the double-sided lifting mechanism 40 in this embodiment includes: an L-shaped lifting arm 41, a seat plate drive gear 42, a seat plate bearing washer 43, a seat plate bearing 44, a seat plate fixing block 45, a guide rod fixing block 47, a guide rod 48, a lead screw 49, a lifting support shell 50, a locking pin 51, a lower lifting fixing block 52, a lifting driven bevel gear 53, a lifting drive bevel gear 54, a drive spur gear 55, and a lifting support cover 56.

[0044] The drive spur gear 55 has a round hole at the rear, which is connected to the drive shaft 72 in the central follow-up control box 70. The two are interference-fitted and fixed by a set screw, which is used to drive the double-sided lifting mechanism 40 to move back and forth.

[0045] The lifting drive bevel gear 54 has a round hole at its rear, which is connected to the transmission shaft 72 in the central follow-up control box 70. The two are interference-fitted and fixed by a set screw, and are used to drive the lifting driven bevel gear 53. The lifting driven bevel gear 53 has a round hole at its rear, which is connected to the lead screw 49. The two are interference-fitted and fixed by a set screw, and are used to drive the double-sided lifting mechanism 40 to rise and fall. The lower half of the lead screw 49 is smooth and fitted with a bearing, which is locked onto the lower lifting fixing block 52. The lower lifting fixing block 52 is locked onto the lifting support shell 50 and the lifting support cover 56. The lifting support shell 50 and the lifting support cover 56 have grooves that are adapted to the lower lifting fixing block 52 and are interference-fitted. When the lifting support cover 56 and the lifting support shell 50 are installed, the lower lifting fixing block 52 is completely fixed.

[0046] A guide rod 48 is mounted on the lifting support housing 50. The lifting support housing 50 has a circular hole matching the size of the guide rod 48, and the two are interference-fitted. This guide rod guides the L-shaped lifting arm 41 up and down, preventing the L-shaped lifting arm 41 from rotating around the lead screw 49. A guide rod fixing block 47 is mounted above the guide rod 48. The lifting support housing 50 has a groove that matches the guide rod fixing block 47, and the two are interference-fitted. The guide rod fixing block 47 has a through hole matching the size of the guide rod 48, and the two are interference-fitted. The guide rod fixing block 47 has a set screw hole. The upper part of the lifting support housing 50 has a lifting support housing groove that matches the size of the guide rod fixing block 47. By inserting the guide rod fixing block 47 into the lifting support housing groove and tightening the set screw into the set screw mounting hole, the guide rod fixing block 47 and the lifting support housing 50 are fixed.

[0047] The lifting support housing 50 has a protruding limiter on its upper part to prevent the L-shaped lifting arm 41 from detaching beyond its limit. The L-shaped lifting arm 41 is installed inside the lifting support housing 50 and the lifting support cover 56, and is fitted with a lead screw 49 and a guide rod 48. After the lifting support housing 50 and the lifting support cover 56 are installed, the L-shaped lifting arm 41 and the lifting support part are fitted with a clearance fit. The lifting support housing 50 has a set screw hole for screw connection with the lifting support cover 56, and a dovetail pin is provided on the rear side for installing a retaining pin 51 to further strengthen the connection between the two.

By inserting the dovetail pin into the strip-shaped dovetail groove and tightening the set screw into the set screw mounting hole, the lifting support shell 50 and the lower lifting fixing block 52 are fixed.

[0049] The mounting block 45 on the base plate has two grooves. One groove is adapted to the size of the base plate bearing 44, and the two are interference-fitted to fix the base plate bearing 44. The other groove is adapted to the size of the drive motor that controls the opening and closing of the base plate 33, and the two are interference-fitted to fix the drive motor.

[0050] The upper part of the L-shaped lifting arm 41 is provided with a groove that is compatible with the fixing block 45 on the seat plate. The two are interference-fitted, and the fixing block 45 on the seat plate and its internal components can be inserted together into the groove on the upper part of the L-shaped lifting arm 41. The rear side of the L-shaped lifting arm 41 is provided with 14 through holes for installing driven pulleys. When the L-shaped lifting arm 41 is lowered onto the bed, the bed provides sufficient support force to the driven pulleys to prevent the multi-scenario intelligent elderly assistive transfer device 1 from tilting backward.

[0051] The rear of the seat plate drive gear 42 has a round hole, which is connected to the output shaft of the drive motor that controls the opening and closing of the seat plate 33. The two are interference-fitted and fixed by a set screw, which is used for the opening and closing of the seat plate 33.

[0052] The centrally located follow-up control box 70 is positioned between the two lifting mechanisms 40. It contains a PCB board, a voice module 35, a dual-output shaft geared motor 74, and other modules for receiving, processing, and outputting control commands. The central position also prevents the two lifting mechanisms 40 from tilting inward, thus improving structural rigidity.

[0053] Figure 4 This is a schematic diagram of the structure of the centrally located follow-up control box of the multi-scenario intelligent elderly assistive relocation device in an embodiment of the present invention.

[0054] like Figure 4 As shown, the centrally located follow-up control box 70 in this embodiment includes: control box bottom 71, transmission shaft 72, lower coupling 73, dual output shaft geared motor 74, main control board 75, control box cover 76, and motor bracket 80.

[0055] The control box bottom 71 is placed in the middle of the double-sided lifting mechanism 40 to support the double-sided lifting mechanism 40 and prevent it from tilting inward.

[0056] The bottom right side of the control box 71 has a square hole for power cable access; the sides have square holes for leading the power and communication cables of the modules on the PCB board, including the main control board 75, out to the central follow-up control box 70; the edge of the control box 71 has a long barb for installing the control box cover 76; the sides also have several through holes for connecting the set screws to the double-sided lifting mechanism 40, and also for the drive shaft 72 to output power; the control box 71 has a recessed groove in the middle, the shape of which is the same as that of the motor bracket 80, and the two are interference fit, and the groove has four through holes for bolt connection between the motor bracket 80 and the control box 71;

[0057] The motor bracket 80 is divided into a symmetrical right motor bracket 81 and a left motor bracket 82. The left and right motor brackets 80 have protrusions that can securely fix the dual-output shaft geared motor 74. The left and right motor brackets 80 have concentric through stepped holes. After the motor is installed in the motor bracket 80, bolts are used to tighten the mounting holes to clamp the dual-output shaft geared motor 74. Then, bolts are used to fix the motor bracket 80 in the recessed groove at the bottom of the control box 71. The lower part of the motor bracket 80 has holes through which the power cord of the dual-output shaft geared motor 74 is connected to the PCB board.

[0058] The dual-output shaft geared motor 74 is a high-speed motor that outputs power to both sides at low speeds via a gear set.

[0059] The output shaft of the dual-output shaft geared motor 74 is connected to the transmission shaft 72 via the lower coupling 73. The transmission shaft 72 is made of high-strength steel and has strong torsional resistance.

[0060] After the motor bracket 80 is installed to the bottom 71 of the control box, there is a large gap between the front side of the motor bracket 80 and the control box cover 76, which is just enough to install the voice module 35. The control box cover 76 has honeycomb-shaped holes at the corresponding position of the voice module 35 for sound diffusion and propagation, and also has a slot for the voice module 35 to lock the voice module 35 and prevent the voice module 35 from shaking violently during operation.

[0061] The curved handrail assist mechanism 100 is located on the outside of the double-sided lifting mechanism 40 and is used to drive the handrail 110 to be lifted in a curved manner. The handrail 110 has ratchet folding and adjustment functions to meet the needs of users of different body types.

[0062] Figure 5 This is a schematic diagram of the outer side of the curved handrail assist mechanism of the multi-scenario intelligent elderly assist shifter in an embodiment of the present invention. Figure 6 This is a schematic diagram of the inner structure of the curved handrail assist mechanism of the multi-scenario intelligent elderly assist device in an embodiment of the present invention.

The handrail 110 also includes a grip 113, an elbow rest 111, a handrail connecting rod 112, a handrail support rod 117, a handrail rotating ratchet 119, a handrail rotating spring 114, a handrail rotating bearing 120, a handrail rotating bearing plug 116, a handrail storage ratchet head 118, and a handrail lead screw 133.

[0064] The handrail motor housing 134 has several through holes on its rear side, and the L-shaped lifting arm 41 has corresponding set screw holes. The two are fixed together by set screws, so that the entire curved handrail assist mechanism 100 is installed on the L-shaped lifting arm 41. The handrail motor housing 134 and the handrail motor cover 136 have protrusions that are adapted to the straight-output shaft reduction motor 132. After the handrail motor housing 134 and the handrail motor cover 136 are installed, the straight-output shaft reduction motor 132 can be completely fixed.
