Description

Technical Field

[0001] The invention belongs to the technical field of bathing assistance, and in particular relates to a split-type docking device for a bathing assistance bathtub and a transfer vehicle. Background Art

[0002] Bathing assistance is a service for the elderly. Bathing assistants carry professional bathing assistance equipment and provide a complete set of bathing assistance services to the elderly in need. Bathing assistants mainly serve the elderly and disabled people, providing deep cleaning effects.

[0003] At present, bathing assistance equipment generally includes a bathing assistance bathtub and a transfer cart (or bathing assistance chair). The bathing assistance bathtub can be flipped and unfolded to form a bathing entrance, and then the transfer cart is pushed in from the bathing entrance and the bathtub door is closed, so that the elderly and disabled people can bathe in the bathtub and sit on the transfer cart.

[0004] However, ordinary transfer carts cannot separate the seat and the walking chassis. Therefore, the whole vehicle occupies a large space after entering the bathtub and has a high center of gravity. If you want to take a bath, you need a larger bathtub and more bath liquid. In addition, the walking chassis will also cause bath liquid contamination, resulting in a poor bathing service experience and difficult operation for the bathing assistant. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an improved split-type docking device for a bathing-assisting bathtub and a transfer vehicle.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] The invention discloses a split-type docking device for a bathing-assisting bathtub and a shifting vehicle. The bathing-assisting bathtub comprises a cylinder body whose door can be turned over to open or close a bathing inlet. The shifting vehicle comprises a bathing-assisting seat capable of adjusting a sitting posture and a walking chassis which is separately installed at the bottom of the bathing-assisting seat through a self-locking component. In particular, the self-locking component comprises a lock seat installed on the walking chassis and a lock head which is rotatably arranged at the bottom of the bathing-assisting seat and cooperates with the lock seat. The docking device comprises a docking part which is installed in the cylinder body and forms a motion guide along the length direction of the cylinder body, a positioning part which is installed at the bottom of the cylinder body, and a matching part which is installed on the walking chassis and cooperates with the lock head. When the shifting vehicle enters from the bathing inlet and triggers the lock head to rotate, the lock head is separated from the lock seat to separate the bathing-assisting seat from the walking chassis, and the matching part is linked and interlocked with the positioning part. When the shifting vehicle exits from the bathing inlet and the lock head is rotated and reset, the lock head and the lock seat are self-locked to combine the bathing-assisting seat with the walking chassis, and the matching part is linked and separated from the positioning part.

[0008] Preferably, the docking portion includes a slide rail extending along the direction of entering and exiting the tub body, and a pulley installed at the bottom of the bathing-assisting seat, wherein the pulley slides on the slide rail. Based on the cooperation of the slide rail and the pulley, the bathing-assisting seat can be smoothly delivered into the bathtub.

[0009] In some specific embodiments, there are two slide rails, which are correspondingly distributed on both sides of the width direction of the cylinder body; the pulleys are divided into two groups, which are respectively located on opposite sides of the bottom of the bathing seat. In this way, the horizontal push is more stable and safe, and at least two pulleys are used, so the support effect is best.

[0010] According to a specific implementation and preferred aspect of the present invention, the alignment part and the matching part are interlocked by hooking, and the matching part is installed on the walking chassis with an upward movement tendency. Based on the interlocking of the alignment part and the matching part, the walking chassis and the cylinder body after separation are relatively locked; conversely, when the bathing seat is withdrawn, the alignment part and the matching part can be separated to realize the combination of the shifting vehicle.

[0011] Preferably, the matching part is a locking hook, and the aligning part is a locking module matched with the locking hook, wherein the locking module is hook-shaped, block-shaped or rod-shaped. The hooking method makes the docking of the two more stable.

[0012] According to another specific implementation and preferred aspect of the present invention, the lock is installed on the bottom of the bath-assisting seat by a torsion spring that maintains a downward movement tendency. Here, the lock is automatically reset based on the torsion spring. A pressure rod is also provided on the lock, wherein the pressure rod can be pressed on the matching part to form a linkage. When the pressure rod is separated from the matching part, the matching part is reset and interlocked with the alignment part. That is, the self-locking or unlocking is linked with the matching part state by the triggering or disengagement of the pressure rod, so that when combined, the matching part and the alignment part are separated; when separated, the matching part and the alignment part are interlocked. A roller is also provided on the lock, and when the lock is triggered and rotated, the roller fits the cylinder body or the docking part slides in the cylinder body. The rolling energy formed by the roller can avoid the lock from causing movement damage to the cylinder body.

[0013] Preferably, the lock seat comprises a seat body having a platform portion and a slope foot portion, and when self-locking is formed, the lock head abuts against the junction of the platform portion and the slope foot portion, and the relative movement of the lock head is limited based on the blocking formed by the slope foot portion and the torsion force of the torsion spring itself.

[0014] Furthermore, a conflicting limit module is provided at the bottom of the cylinder body, and a movable lock hook is provided on the lock seat to keep the lock head hooked to the foot of the slope, wherein during the split operation, the movable lock hook is resisted by the conflicting limit module to drive the movable lock hook to detach from the lock head. In some specific embodiments, the movable lock hook is slidably arranged along the length direction of the seat body, and a positioning seat and a tension spring are also provided on the walking chassis, wherein the two ends of the tension spring are respectively installed on the positioning seat and the movable lock hook to maintain the tensioning hooking trend to form the self-locking of the lock head and the lock seat; further, a trigger rod is provided on the movable lock hook, wherein the conflicting limit module and the trigger rod conflict to drive the movable lock hook to slide and unhook. Here, the movement of the movable lock hook is not only linked with the combined and split movements, so as to further improve the stability and safety of the self-locking of the lock head and the lock seat, but also can further enhance the self-locking performance of the lock head and the lock seat based on the hooking.

[0015] In addition, the docking device also includes a receiving ramp portion provided at the bathing port of the cylinder body, wherein the receiving ramp portion gradually slopes downward from the inside to the outside. Based on the setting of the receiving ramp portion, it is convenient for the separated bathing seat to enter and exit the cylinder body from the bathing port, reducing collision damage, and at the same time meeting the position alignment requirements required for separation and combination.

[0016] At the same time, the docking device also includes a guide channel provided at the bottom of the cylinder body, wherein the walking chassis enters the bottom of the cylinder body along the guide channel. That is, the movement guidance of the walking chassis is achieved by the setting of the guide channel. It is convenient to cause the collision between the walking chassis and the cylinder body, and can meet the position alignment requirements required for separation and combination.

[0017] Due to the implementation of the above technical solution, the present invention has the following advantages compared with the prior art:

[0018] In the existing bathing assistance, the shifting cart cannot separate the seat and the walking chassis. Therefore, the whole vehicle occupies a large space after entering the bathtub and has a high center of gravity. If bathing is to be carried out, the required bathtub is larger and more bath liquid is required. In addition, the walking chassis will also cause bath liquid pollution, resulting in a poor bathing service experience and difficult operation for the bathing assistant, etc. The present invention cleverly solves various deficiencies of the existing structure by overall design of the split docking device of the bathing assistance bathtub and the shifting cart. After adopting the split docking device of the bathing-assisting bathtub and the shifting vehicle, the door is opened to form a bathing entrance, the shifting vehicle is aligned with it, and then the self-service bathing seat of the shifting vehicle enters the cylinder body, and the self-propelled chassis enters the bottom of the cylinder body, until the cylinder body triggers the lock to rotate, the lock head and the lock seat are disengaged to separate the bathing-assisting seat from the walking chassis, and at the same time the matching part is linked and interlocked with the alignment part to relatively position the walking chassis and the bottom of the cylinder body, the bathing-assisting seat enters the cylinder body along the guided docking part, and then the door is closed to enable the user to bathe on the bathing-assisting seat. Therefore, the present invention On the one hand, based on the touch, locking and linkage formed by the docking device, the shifting cart and the cylinder body, the precise alignment of the bathing separate part and the bathing combined part of the shifting cart can be achieved, so that the bathing assistance seat can enter and exit the bathtub; on the other hand, there is no need for the entire shifting cart to enter and exit the cylinder body, which effectively lowers the center of gravity of the bathing assistance seat, that is, it not only reduces the risk of bathing, but also facilitates the operation of the bathing assistant. At the same time, there is no need to change the volume of the cylinder body, and the angle adjustment of the bathing assistance seat allows the user to bathe in a comfortable posture, which greatly increases the user's physical sensation. In addition, it can also prevent the walking chassis from entering and causing contamination of the bath fluid. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] like Figures 1 to 6 As shown, the bathing assistance equipment involved in this embodiment includes a bathing assistance bathtub 1, a shifting vehicle 2 and a docking device 3.

[0035] Specifically, the bathing-assisted bathtub 1 includes a cylinder body 10 with a door 100 that can be flipped to open or close a bathing inlet, wherein the door 100 is flipped from one side around the up and down direction and connected to the cylinder body 10, and the door 100 and the cylinder body 10 can be sealed, docked and locked.

[0036] The shifting vehicle 2 includes a bathing-assisting seat 20 capable of adjusting the sitting posture, and a walking chassis 22 separately installed at the bottom of the bathing-assisting seat 20 through a self-locking component 21, wherein the self-locking component 21 includes a lock seat 210 installed on the walking chassis 22, and a lock head 211 rotatably set at the bottom of the bathing-assisting seat 20 and cooperating with the lock seat 210.

[0037] The docking device 3 includes a docking portion 30 installed in the cylinder body 10 and forming a motion guide along the length direction of the cylinder body 10, a positioning portion 31 installed at the bottom of the cylinder body 10, and a matching portion 32 installed on the walking chassis 22 and cooperating with the lock head 211.

[0038] In some specific embodiments, the docking portion 30 includes a slide rail 300 extending along the direction of entering and exiting the cylinder body 10, and a pulley 301 installed at the bottom of the bathing seat 20, wherein the pulley 301 slides on the slide rail 300. Based on the cooperation of the slide rail and the pulley, the bathing seat can be smoothly sent into the bathtub. In this example, there are two slide rails 300, which are correspondingly distributed on both sides of the width direction of the cylinder body 10; the pulley 301 is divided into two groups, and is respectively located on the opposite sides of the bottom of the bathing seat 20. In this way, the horizontal push is more stable and safe, and at the same time, at least two pulleys are used, and the support effect formed is the best. The alignment portion 31 and the matching portion 32 are interlocked by hooking, and the matching portion 32 is installed on the walking chassis 22 to maintain the upward movement trend, and the matching portion 32 is a lock hook, and the alignment portion 31 is a locking module matched with the lock hook, wherein the locking module is hook-shaped or block-shaped or rod-shaped. The hooking method is adopted to make the docking of the two more stable. At the same time, based on the interlocking of the alignment part 31 and the matching part 32, the separated walking chassis 22 and the cylinder body 10 are relatively locked; conversely, when the bathing seat 20 is withdrawn, the alignment part 31 and the matching part 32 can be separated to realize the combination of the shifting vehicle 2.

[0039] In this example, the lock seat 210 includes a seat body T having a platform portion a and a slope foot portion b. When self-locking is formed, the lock head 211 contacts the junction of the platform portion a and the slope foot portion b. The relative movement of the lock head 211 is limited by the blocking formed by the slope foot portion b and the torsion force of the torsion spring itself. The lock head 211 is installed at the bottom of the bathing seat 20 by a torsion spring that maintains a downward movement trend. Here, the automatic reset of the lock head is achieved based on the torsion spring. A pressure rod g1 is also provided on the lock head 211, wherein the pressure rod g1 can be pressed on the matching portion 32 to form a linkage. When the pressure rod g1 is separated from the matching portion 32, the matching portion 32 is reset and interlocked with the alignment portion 31. That is, the self-locking or unlocking is linked to the matching portion 32 state by the triggering or disengagement of the pressure rod g1, so that when the body is combined, the matching portion 32 is separated from the alignment portion 31; when the body is separated, the matching portion 32 is interlocked with the alignment portion 31. The lock head 211 is also provided with a roller g2. When the lock head 211 is triggered and rotated, the roller g2 slides in the cylinder body 10 by fitting the cylinder body 10 or the docking portion 31. The rolling energy formed by the roller can prevent the lock head from causing movement damage to the cylinder body. At the same time, a resistance limit module 212 is provided at the bottom of the cylinder body 10, and a movable lock hook 213 is provided on the lock seat 210 to keep the lock head 211 hooked to the slope foot b. When the split operation is performed, the movable lock hook 213 is resisted by the resistance limit module 212 and drives the movable lock hook 213 to separate from the lock head 211.

[0040] In some specific embodiments, the movable locking hook 213 is slidably arranged along the length direction of the seat body T, and a positioning seat 214 and a tension spring 215 are also provided on the walking chassis 22, wherein the two ends of the tension spring 215 are respectively installed on the positioning seat 214 and the movable locking hook 213 to maintain the tensioning hooking trend to form self-locking of the locking head 211 and the locking seat 210.

[0041] In this example, a trigger rod g3 is provided on the movable lock hook 213, wherein the contact limit module 212 and the trigger rod g3 contact to drive the movable lock hook 213 to slide and unhook. Here, the equivalent movement of the movable lock hook 213 and the combined and separated movement also form a linkage to further improve the stability and safety of the self-locking of the lock head and the lock seat.

[0042] In addition, the docking device 3 also includes a receiving channel 33 arranged at the bottom of the cylinder body 10 and a receiving ramp portion 34 arranged at the bathing port of the cylinder body 10, wherein the walking chassis 22 enters the bottom of the cylinder body 10 along the receiving channel 33, that is, the movement guidance of the walking chassis is realized by the setting of the receiving channel; the receiving ramp portion 34 gradually tilts downward from the inside to the outside. Based on the setting of the receiving ramp portion 34, it is convenient for the separated bathing seat 20 to enter and exit the cylinder body 10 from the bathing port, reduce collision damage, and at the same time meet the requirements of the position alignment required for separation and combination.

[0043] In summary, the bathing process of this embodiment is as follows:

Then, the self-service bathing seat 20 of the shift cart 2 enters the cylinder body 10, and the self-propelled chassis 22 enters the bottom of the cylinder body 10, until the cylinder body 10 triggers the lock 211 to rotate, the lock 211 is disengaged from the lock seat 210 to separate the bathing seat 20 from the walking chassis 22, and at the same time, the matching part 32 is linked and interlocked with the alignment part 31 to relatively position the walking chassis 22 and the bottom of the cylinder body 10, the bathing seat 20 enters the cylinder body 10 along the guiding docking part 30, and then the door 100 is closed to enable the user to bathe on the bathing seat 20.

[0045] The bathing process of this embodiment is as follows:

[0046] After opening the door 100, the bath-assisting seat 20 is moved outward from the outer cylinder body 10. When the lock head 211 realizes the restriction and rotates downward to the aligned lock seat 210 under the reset of the torsion spring, the pressure rod g1 contacts the matching part 32 to unlock the matching part 32 and the aligned part 31. At the same time, the trigger rod g3 disengages from the interference limit module 212, and the movable lock hook 213 is hooked on the lock head 211 under the pull of the tension spring 215. The lock head 211 is in contact with the junction of the platform part a and the slope foot part b and forms a self-locking with the lock seat 210 to complete the relative combination of the bath-assisting seat 20 and the walking chassis 22.

[0047] Therefore, after adopting the split docking device of the bathing-assisting bathtub and the shifting cart, the door is opened to form a bathing entrance, the shifting cart is aligned with it, and then the self-service bathing seat of the shifting cart enters the cylinder body, and the self-propelled chassis enters the bottom of the cylinder body, until the cylinder body triggers the lock to rotate, the lock and the lock seat are disengaged to separate the bathing-assisting seat from the walking chassis, and at the same time the matching part is linked and interlocked with the alignment part to relatively position the walking chassis and the bottom of the cylinder body, the bathing-assisting seat enters the cylinder body along the guided docking part, and then the door is closed to enable the user to bathe on the bathing-assisting seat.
