[0001] The present application relates to the technical field of bathtubs, and in particular to an intelligent transfer device for a bathtub. Background Art
[0002] Bathtubs are a type of plumbing device that is usually installed in home bathrooms for bathing or showering. In the early days, users were required to enter the bathtub by themselves, which was difficult for users with limited mobility. Therefore, smart bathtubs that can move users in or out have emerged.
[0003] Traditional smart bathtubs are usually equipped with seats. When the seat is used to put the user in or out of the bathtub, it is necessary to move the seat horizontally and lift it up and down. Smart bathtubs are usually installed in the bathroom. Due to the limited space in the bathroom, the seat's movable space is also smaller. When the bathroom space is seriously insufficient or the user is large, the seat's movable space is further limited. When the seat is used to transport the user, the user's calf is difficult to be higher than the edge of the bathtub. At this time, traditional horizontal movement and lifting operations make it difficult to easily put the user in or out of the smart bathtub.
[0004] Improvements are urgently needed to address the above issues. Utility Model Content

At this time, the first lifting arm does not need to rise to an excessively high height to enable the seat to send the user into or out of the bathtub; when the user enters or moves out of the bathtub, the output end of the electric push rod retracts to drive the swing rod to rotate, and the seat leaves the reclining state as the swing rod rotates. At this time, the user's back leaves the reclining state and the height of the calf naturally decreases, achieving a comfortable sitting posture.The large and fixed length space of the bathtub is fully utilized to make up for the lack of indoor height space, so that even when the space is small, the user can achieve convenient transfer; a slide groove is opened in the middle of the bracket along the height direction, and a slider is slidably connected to the slide groove, and one end of the slider close to the electric push rod is hinged to the output end of the electric push rod, and one end of the slider close to the swing rod is hinged to the end of the swing rod away from the seat. Through the arrangement of the above structure, a more accurate adjustment effect is provided for the inclination angle of the seat, and by observing the specific sliding position of the slider in the slide groove, the electric push rod is controlled to reach a more accurate output length, so that the swing rod is rotated to the target position, so that the seat reaches a reasonable and accurate inclination angle, thereby ensuring that the user sitting on the seat is at a reasonable and accurate inclination angle, so that the height of the calf is more reasonably and accurately raised within the limited height space range, so that the user's calf can be easily and smoothly higher than the height of the bathtub within the limited height space, which is convenient for the user to get in and out of the bathtub with the seat, and thus even when the space is small, the user can achieve convenient transfer; There are two electric push rods and two swing rods, which are symmetrically arranged on both sides of the bracket along the width direction of the bathtub. One end of each swing rod is hinged to the output end of the electric push rod on the same side, and the other end of each swing rod is connected to the top of the seat on the same side. Through the arrangement of the above structure, while facilitating the control of the seat to adjust the tilt angle, the seat also has more sufficient stability during the process of adjusting the tilt angle, preventing the seat from shaking or unbalanced center of gravity, ensuring the connection stability between the various components, and thus ensuring that the user can perform convenient and safe transfer operations with the seat; the two swing rods are connected to a reinforcing rod on the side facing each other, and the axial position of the reinforcing rod corresponds to the rotation center position of the swing rod. Through the arrangement of the above structure, during the rotation of the swing rod, the reinforcing rod provides an axial outward supporting force for the two swing rods, preventing the swing rod from being dislocated or loosened, and ensuring the stability and safety of the seat during the process of adjusting the tilt angle, so that when the space is small, the user can conveniently transfer in and out of the bathtub.

[0034] Specifically, a traditional smart bathtub is usually provided with a seat 5, and the seat 5 needs to be moved horizontally and lifted when the user is put in or out of the bathtub. The smart bathtub is usually installed in the bathroom. Due to the limited space in the bathroom, the activity space of the seat 5 is also smaller. When the space in the bathroom is seriously insufficient or the user is large, the activity space of the seat 5 is further limited. When the user is transported by the seat 5, the user's calf is difficult to be higher than the edge of the bathtub. At this time, the traditional horizontal movement and lifting operations cannot easily put the user in or out of the smart bathtub. Therefore, in order to solve the above problems, the intelligent transfer device for the bathtub provided in the present application includes a base 1 arranged on the outside of the bathtub, and the base 1 is provided with a first guide rail 101 along the width direction of the bathtub, which is used to provide the seat 5 with stroke adjustment along the width direction of the bathtub, and a first lifting arm 102 is slidably arranged on the first guide rail 101, which is used to provide the seat 5 with stroke adjustment along the height direction of the bathtub, and the top of the first lifting arm 102 is connected with a bracket 2 toward the bathtub, which is used to provide an installation and support basis for the seat 5; it also includes an electric push rod 3, a rocker arm 4, and a seat 5, the top of the bracket 2 is hinged to the fixed end of the electric push rod 3, the bottom of the bracket 2 is hinged to the middle part of the rocker arm 4, one end of the rocker arm 4 is hinged to the output end of the electric push rod 3, and the other end of the rocker arm 4 is connected to the top of the seat 5. Through the above-mentioned structure, when the user sitting on the seat 5 needs to enter or exit the bathtub, the output end of the electric push rod 3 pushes out to drive the swing rod 4 to rotate, and the seat 5 is tilted back with the rotation of the swing rod 4. At this time, as the seat 5 is tilted back, the user's back is tilted back and the height of the calf is increased, so that the user can easily and smoothly exceed the height of the bathtub in a limited height space, which is convenient for entering and exiting the bathtub with the seat 5. At this time, the first lifting arm 102 does not need to rise to an excessively high height to realize that the seat 5 can send the user into or out of the bathtub; when the user enters or moves out of the bathtub, the output end of the electric push rod 3 retracts to drive the swing rod 4 to rotate, and the seat 5 is out of the tilted state with the rotation of the swing rod 4. At this time, the user's back is out of the tilted state and the height of the calf is naturally reduced, achieving a comfortable sitting posture. In this way, the larger and fixed length space of the bathtub is fully utilized to make up for the lack of indoor height space, so that even when the space is small, the user can be conveniently transferred.
[0035] In some preferred embodiments, a slide groove 201 is opened in the middle of the bracket 2 along the height direction, and the slide groove 201 is slidably connected with a slider 6. One end of the slider 6 close to the electric push rod 3 is hinged to the output end of the electric push rod 3, and one end of the slider 6 close to the rocker arm 4 is hinged to the end of the rocker arm 4 away from the seat 5.
[0036] Specifically, a slide groove 201 is provided in the middle part of the bracket 2 along the height direction, and a slider 6 is slidably connected to the slide groove 201. The end of the slider 6 close to the electric push rod 3 is hinged to the output end of the electric push rod 3, and the end of the slider 6 close to the swing rod 4 is hinged to the end of the swing rod 4 away from the seat 5. Through the arrangement of the above structure, a more accurate adjustment effect is provided for the inclination angle of the seat 5. By observing the specific sliding position of the slider 6 in the slide groove 201, the electric push rod 3 is controlled to achieve a more accurate output length, so that the swing rod 4 is rotated to the target position, and the seat 5 reaches a reasonable and accurate inclination angle, thereby ensuring that the user sitting on the seat 5 is at a reasonable and accurate inclination angle, so that the height of the calf can be more reasonably and accurately raised within the limited height space, so that the user's calf can be easily and smoothly higher than the height of the bathtub within the limited height space, which is convenient for the user to enter and exit the bathtub with the seat 5, and thus even when the space is small, the user's convenient transfer can be achieved.
[0037] In some preferred embodiments, there are two electric push rods 3 and two rocker arms 4, and the two electric push rods 3 are symmetrically arranged on both sides of the bracket 2 along the width direction of the bathtub. One end of each rocker arm 4 is hinged to the output end of the electric push rod 3 on the same side, and the other end of each rocker arm 4 is connected to the top of the seat 5 on the same side.
[0038] Specifically, there are two electric push rods 3 and two rocker arms 4, which are symmetrically arranged on both sides of the bracket 2 along the width of the bathtub. One end of each rocker arm 4 is hinged to the output end of the electric push rod 3 on the same side, and the other end of each rocker arm 4 is connected to the top of the seat 5 on the same side. Through the arrangement of the above structure, while it is convenient to control the seat 5 to adjust the tilt angle, the seat 5 also has more sufficient stability during the process of adjusting the tilt angle, preventing the seat 5 from shaking or unbalancing the center of gravity, ensuring the connection stability between the components, and thus ensuring that the user can perform convenient and safe transfer operations with the seat 5.
[0039] In some preferred embodiments, the two swing arms 4 are connected with a reinforcing rod 7 on the sides facing each other, and the axial position of the reinforcing rod 7 corresponds to the rotation center position of the swing arm 4 .
[0040] Specifically, the two rocker arms 4 are connected with a reinforcing rod 7 on the sides facing each other, and the axial position of the reinforcing rod 7 corresponds to the rotation center position of the rocker arms 4. Through the arrangement of the above structure, during the rotation of the rocker arms 4, the reinforcing rod 7 provides an axial outward supporting force for the two rocker arms 4, thereby preventing the rocker arms 4 from being misplaced or loosened, thereby ensuring the stability and safety of the seat 5 during the process of adjusting the tilt angle, so that the user can conveniently transfer in and out of the bathtub even when the space is small.
[0041] In some preferred embodiments, a hook 8 is provided on the top of the seat 5 and is bent obliquely downward. The hook 8 is hung on the radial outer wall of the reinforcing rod 7. A limiting wheel 9 is extended outward on one side of the seat 5 close to the free end of the bottom of the rocker arm 4. The limiting wheel 9 abuts against the outer wall of the free end of the bottom of the rocker arm 4.
[0042] Specifically, during daily use, the seat 5 often needs to be disassembled or repaired. In order to realize convenient transfer for the user and convenient disassembly of the seat 5, in the present embodiment, a hook 8 is provided on the top of the seat 5 bent obliquely downward, and the hook 8 is hung on the radial outer wall of the reinforcing rod 7. A limiting wheel 9 is extended outward on one side of the seat 5 close to the free end of the bottom of the swing rod 4, and the limiting wheel 9 abuts against the outer wall of the free end of the bottom of the swing rod 4. Through the arrangement of the above structure, the hook 8 and the radial outer wall of the reinforcing rod 7 form a convenient and stable hanging structure to realize quick connection and connection. For stable use after use, the limiting wheel 9 plays a limiting role and realizes abutment with the outer wall of the free end at the bottom of the swing rod 4. Under the action of the gravity of the seat 5 and the user, the seat 5 is connected with the radial outer wall of the reinforcing rod 7 through the hook 8, and the limiting wheel 9 is in abutment with the outer wall of the free end at the bottom of the swing rod 4, so as to realize a stable matching connection with the swing rod 4. When the swing rod 4 rotates, the seat 5 rotates synchronously with the swing rod 4 to achieve the target tilt angle, ensuring that the user is higher than the height of the bathtub within a limited height space, making it convenient for the user to enter and exit the bathtub synchronously with the seat 5, and realizing convenient transfer operation.
[0043] In some preferred embodiments, the hook 8 is provided with an arc-shaped opening, and the size of the arc-shaped opening is adapted to the size of the radial outer wall of the reinforcing rod 7 .
[0044] Specifically, on the one hand, the seat 5 forms a stable connection structure with the radial outer wall of the hook 8 and the reinforcing rod 7. On the other hand, the seat 5 uses the connection between the hook 8 and the radial outer wall of the reinforcing rod 7 as the rotation center, so that the limiting wheel 9 rotates to the target position and forms a stable abutment with the outer wall of the free end at the bottom of the swing rod 4. In order to make the connection between the seat 5 and the reinforcing rod 7 more stable and firm, and at the same time facilitate the rotation of the seat 5 to the target position, so that the limiting wheel 9 and the outer wall of the free end at the bottom of the swing rod 4 form a stable abutment structure, in this embodiment, the hook 8 is provided with an arc-shaped opening, and the size of the arc-shaped opening is adapted to the size of the radial outer wall of the reinforcing rod 7. Thus, a tight and stable rotation connection structure is formed between the hook 8 and the reinforcing rod 7, thereby realizing a stable connection between the seat 5 and the reinforcing rod 7, and at the same time facilitating the rotation of the seat 5 to the target position, realizing the stable abutment between the limiting wheel 9 and the outer wall of the free end at the bottom of the swing rod 4, thereby realizing the convenient operation of the user entering and exiting the bathtub with the seat 5.
[0045] In some preferred embodiments, the bottom surface of the seat 5 is provided with guide wheels 10 along the width direction of the bathtub.
[0046] Specifically, under the hooking of the hook 8 and the reinforcing rod 7, and the abutting action of the limiting wheel 9 and the rocker arm 4, the seat 5, the reinforcing rod 7, and the rocker arm 4 achieve a convenient disassembly and connection effect. In order to further improve the convenience of the seat 5 for the user during the transfer and transportation process, in the present embodiment, the bottom surface of the seat 5 is provided with a guide wheel 10 along the width direction of the bathtub. Through the guide wheel 10, the seat 5 is conveniently moved, and the seat 5 is conveniently moved to the designated position to form a stable connection structure with the reinforcing rod 7 and the rocker arm 4. At the same time, the transfer operation before and after disassembly and assembly becomes more convenient, thereby facilitating the subsequent convenient transfer of users in a small space.

[0048] Specifically, when the user sits on the seat 5, due to the different personal needs of the user, the seat 5 also needs to adjust its own angle to meet the user's sitting angle needs. Therefore, in the present embodiment, the seat 5 includes a backrest portion 501 and a seat plate portion 502. A first adjustment plate 5011 is provided at the bottom of the backrest portion 501. The first adjustment plate 5011 is sequentially provided with a plurality of first adjustment holes along the radial edge. A second adjustment plate 5021 is provided on one side of the seat plate portion 502. The second adjustment plate 5021 is sequentially provided with a plurality of second adjustment holes along the radial edge. One of the first adjustment holes is connected to one of the second adjustment holes. The node holes are spliced correspondingly and connected by adjusting bolts. Through the setting of the above-mentioned structure, the first adjustment plate 5011 and the second adjustment plate 5021 can rotate relative to each other. When reaching the target position, one of the first adjustment holes and one of the second adjustment holes are spliced correspondingly and connected by adjusting bolts, thereby completing the adjustment and locking of the specific angle, so that the backrest part 501 and the seat plate part 502 of the seat 5 can reach the user's required angle, ensuring that the user has sufficient riding comfort while transferring with the seat 5, and can also get a good comfortable experience when the user leans back with the seat 5 in and out of the bathtub.
[0049] In some preferred embodiments, the backrest portion 501 includes a first frame 511 and a second frame 512 which are arranged from top to bottom, and the first frame 511 and the second frame 512 are connected via a first telescopic rod 11 .

[0053] Through the above technical scheme, the intelligent transfer device for the bathtub provided in the present application includes a base 1 arranged on the outside of the bathtub, and the base 1 is provided with a first guide rail 101 along the width direction of the bathtub, which is used to provide the seat 5 with stroke adjustment along the width direction of the bathtub, and a first lifting arm 102 is slidably arranged on the first guide rail 101, which is used to provide the seat 5 with stroke adjustment along the height direction of the bathtub, and the top of the first lifting arm 102 is connected with a bracket 2 toward the bathtub, which is used to provide an installation and support basis for the seat 5; it also includes an electric push rod 3, a rocker arm 4, and a seat 5, the top of the bracket 2 is hinged to the fixed end of the electric push rod 3, the bottom of the bracket 2 is hinged to the middle part of the rocker arm 4, one end of the rocker arm 4 is hinged to the output end of the electric push rod 3, and the other end of the rocker arm 4 is connected to the top of the seat 5. By setting the above structure, when the user sitting on the seat 5 needs to enter or exit the bathtub, the output end of the electric push rod 3 pushes out to drive the swing rod 4 to rotate, and the seat 5 is tilted back as the swing rod 4 rotates. At this time, as the seat 5 tilts back, the user's back tilts back and the height of the calf increases, so that the user can easily and smoothly exceed the height of the bathtub in a limited height space, which is convenient for entering and exiting the bathtub with the seat 5. At this time, the first lifting arm 102 does not need to rise to an excessively high height to enable the seat 5 to send the user into or out of the bathtub; when the user enters or moves out of the bathtub, the output end of the electric push rod 3 retracts to drive the swing rod 4 to rotate, and the seat 5 leaves the tilted back state as the swing rod 4 rotates. At this time, the user's back leaves the tilted back state and the height of the calf naturally decreases, achieving a comfortable sitting posture.In this way, the large and fixed length space of the bathtub is fully utilized to make up for the lack of indoor height space, so that even when the space is small, the user's convenient transfer can be achieved; a slide groove 201 is opened in the middle of the bracket 2 along the height direction, and a slider 6 is slidably connected to the slide groove 201. The end of the slider 6 close to the electric push rod 3 is hinged to the output end of the electric push rod 3, and the end of the slider 6 close to the swing rod 4 is hinged to the end of the swing rod 4 away from the seat 5. Through the arrangement of the above structure, a more accurate adjustment effect is provided for the inclination angle of the seat 5. By observing the specific sliding position of the slider 6 in the slide groove 201, the electric push rod 3 is controlled to achieve a more accurate output length, so that the swing rod 4 is rotated to the target position, so that the seat 5 reaches a reasonable and accurate inclination angle, thereby ensuring that the user sitting on the seat 5 is at a reasonable and accurate inclination angle, so that the height of the calf is more reasonably and accurately raised within the limited height space range, so that the user's calf can be easily and smoothly higher than the bathtub height within the limited height space, which is convenient for the user to enter and exit the bathtub with the seat 5, thereby even when the space is small, the user's convenient transfer can be achieved. Shift; the number of electric push rods 3 and swing rods 4 are both two, and the two electric push rods 3 are symmetrically arranged on both sides of the bracket 2 along the width direction of the bathtub. One end of each swing rod 4 is hinged to the output end of the electric push rod 3 on the same side, and the other end of each swing rod 4 is connected to the top of the same side of the seat 5. Through the arrangement of the above structure, while facilitating the control of the seat 5 to adjust the tilt angle, the seat 5 also has more sufficient stability during the adjustment of the tilt angle, preventing the seat 5 from shaking or imbalance of the center of gravity, ensuring the connection stability between the components, and thus ensuring that the user can perform convenient and safe transfer operations with the seat 5; the two swing rods 4 are connected to a reinforcing rod 7 on the side facing each other, and the axial position of the reinforcing rod 7 is kept corresponding to the rotation center position of the swing rod 4. Through the arrangement of the above structure, during the rotation of the swing rod 4, the reinforcing rod 7 provides an axial outward supporting force for the two swing rods 4, preventing the swing rod 4 from being dislocated or loosened, and ensuring the stability and safety of the seat 5 during the adjustment of the tilt angle, so that when the space is small, the user can also conveniently realize the transfer of the user in and out of the bathtub.
