[0002] Our society has now entered an aging society. Groups such as the elderly or disabled people are unable to stand for long periods of time or even stand at all due to the decline in their physical functions. They are also unable to bathe independently and often need the assistance of one or more people to complete a bath; especially those who are bedridden for a long time, it may be impossible to wash their backs for a long time, thus their quality of life is poor. Utility Model Content

[0003] This utility model provides a smart back-washing bathing bed to solve at least one of the above-mentioned technical problems.

[0004] This utility model provides a smart back-washing bathing bed, comprising:

[0005] outer frame;

[0006] At least four bed board mechanisms, each including a flip-up panel, one side of which is rotatably connected to the outer frame, the flip-up panel being configured to rotate to a horizontal closed position or a vertical open position; and

[0007] A cleaning mechanism is movably disposed within the outer frame, wherein the cleaning mechanism is configured such that when the flip plate is in the vertical open position, the cleaning mechanism moves to a cleaning position corresponding to the flip plate; and when the cleaning mechanism moves to the storage position, the flip plate rotates to a horizontal closed position.

[0008] In one embodiment, the outer frame includes a first beam and a second beam that are parallel to each other. The second beam is located inside the first beam and spaced apart from it. The two ends of the flip plate are rotatably connected to the second beam. The flip plate is configured to rotate upward or downward about the connection between the flip plate and the second beam. When the flip plate rotates upward to a horizontal closed position, the upper surface of the flip plate is flush with the first beam. When the flip plate rotates downward to a vertical open position, the side of the flip plate closer to the first beam rotates above the first beam and the side of the flip plate away from the first beam rotates below the first beam.

[0009] In one embodiment, the bed board mechanism further includes:

[0010] An arc-shaped connecting plate, located between the first beam and the second beam, wherein one end of the arc-shaped connecting plate is rotatably connected to the side of the flip plate closest to the first beam; and

[0011] A flip drive is fixedly installed inside the outer frame and rotatably connected to the other end of the arc-shaped connecting plate;

[0012] The arc-shaped connecting plate is configured to extend from between the first and second beams of the outer frame under the drive of the flipping driver, thereby rotating the flipping plate downward to a vertical open position; or to return from between the first and second beams of the outer frame under the drive of the flipping driver, thereby rotating the flipping plate upward to a horizontal closed position.

[0013] In one embodiment, the arc-shaped connecting plate is configured as an arc-shaped structure that protrudes in a direction away from the second beam, wherein when the arc-shaped connecting plate extends or retracts from between the first beam and the second beam of the outer frame, the outer side of the arc-shaped connecting plate remains in contact with the inner edge of the first beam.

[0014] In one embodiment, one of the flip plates of each of the bed plate mechanisms is in a vertically open position, while the other flip plates are simultaneously in a horizontally closed position.

[0015] In one embodiment, the cleaning mechanism includes a cleaning head and a first drive mechanism connected to the cleaning head. The first drive mechanism is connected to the outer frame and is used to move the cleaning head along the height direction of the outer frame.

[0016] When the flip plate is in the vertical open position, the first driving mechanism causes the cleaning head to move upward along the height direction of the outer frame to the cleaning position corresponding to the flip plate; when the flip plate is in the horizontal closed position, the first driving mechanism causes the cleaning head to move downward along the height direction of the outer frame to the storage position.

[0017] In one embodiment, the first drive mechanism is configured as a push rod mechanism, a hydraulic mechanism, a lead screw mechanism, or a belt drive mechanism.

[0018] In one embodiment, the cleaning mechanism further includes a second drive mechanism and a third drive mechanism, and the cleaning head is connected to the first drive mechanism through the second drive mechanism and the third drive mechanism.

The second drive mechanism is used to move the third drive mechanism and the cleaning head along the width direction of the outer frame, and the third drive mechanism is used to move the cleaning head along the length direction of the outer frame.

[0020] In one embodiment, the second drive mechanism is configured as a belt drive mechanism, a lead screw mechanism, or a gear drive mechanism, and the third drive mechanism is configured as a belt drive mechanism, a lead screw mechanism, or a gear drive mechanism.

[0021] Compared with existing technologies, the advantages of this invention are that the flip-up panels can be in a vertically open position or a horizontally closed position. When one of the flip-up panels is in the vertically open position, the user's back corresponding to that panel is exposed. Therefore, the cleaning mechanism can move to the cleaning position corresponding to that panel, allowing for the cleaning of the corresponding area of ​​the user's back. After cleaning, the other flip-up panels can repeat the flip-up action, thus cleaning the corresponding areas of the user's back (including the entire back, legs, and feet). After cleaning, the cleaning mechanism can be moved to the storage position, and the flip-up panels rotate to the horizontally closed position to continue supporting the user. Therefore, this bath bed can clean the user's back (including the entire back, legs, and feet) without moving the user, significantly improving the user's quality of life.

[0057] The present invention will be further described below with reference to the accompanying drawings.

[0058] like Figures 1-19B As shown, this utility model provides an intelligent back-washing shower bed, including an outer frame 1, at least four bed board mechanisms 2, and a washing mechanism 3. The outer frame 1 serves as the overall support and load-bearing structure for the shower bed.

[0059] The upper surface of the bed board mechanism 2 is used to support the user. Specifically, each bed board mechanism 2 includes a flip-up plate 21, one side of which is rotatably connected to the outer frame 1. The flip-up plate 21 is configured to be able to rotate to a horizontal closed position or a vertical open position.

[0060] like Figure 1 and Figure 2 As shown, an example of a bed board mechanism 2 with a quantity of 4 is illustrated, wherein the flip plates of each bed board mechanism 2 are a first flip plate 21a, a second flip plate 21b, a third flip plate 21c, and a fourth flip plate 21d. Figure 1 The diagram shows the state when all four flip panels are in the horizontal closed position. Specifically, the first flip panel 21a and the second flip panel 21b are positioned along the width of the outer frame 1 (e.g.,...). Figure 1 The two are arranged side by side along the Y-axis (as shown), and they open in a split manner; the third flip plate 21c and the fourth flip plate 21d are arranged in the width direction of the outer frame 1 (as shown). Figure 1 The first flip plate 21a and the fourth flip plate 21d are arranged side by side along the Y-axis direction (as shown), and they open in a split manner; the first flip plate 21a and the fourth flip plate 21d are arranged along the length direction of the outer frame 1 (as shown). Figure 1 The second and third flip plates 21b and 21c are arranged side by side along the X-axis direction (as shown), and they open in the same direction; the second flip plate 21b and the third flip plate 21c are arranged along the length direction of the outer frame 1 (as shown). Figure 1They are arranged side by side along the X-axis (as shown), and they open in the same direction.

[0061] Please combine Figure 6A , Figure 6B and Figure 6C To illustrate the cleaning mechanism 3, all the flip-up plates 21 are rotated to the vertically open position. It should be noted that in actual use, not all the flip-up plates 21 are rotated to the vertically open position. The cleaning mechanism 3 can be moved to the cleaning position (e.g., ...). Figure 9 and Figure 10 As shown), this allows for the washing of the user's back on the bed board mechanism 2, and after washing, it returns to its storage position (as shown). Figure 7 and Figure 8 (As shown). The cleaning mechanism 3 is movably disposed in the outer frame 1. The cleaning mechanism 3 is configured such that when the flip plate 21 is in the vertical open position, the cleaning mechanism 3 moves to the cleaning position corresponding to the flip plate 21; and when the cleaning mechanism 3 moves to the storage position, the flip plate 21 rotates to the horizontal closed position.

[0062] Specifically, the outer frame 1 includes a support frame 10 (such as...) Figure 3 and Figure 5 As shown) and a first beam 11 and a second beam 12 that are parallel to each other, wherein the first beam 11 can be integrated into the support frame 10, that is, the first beam 11 can be used as a support beam of the support frame 10. Figure 2 and Figure 3 As shown, both the first beam 11 and the second beam 12 are along the length direction of the outer frame 1 (i.e., Figure 3 Extending along the X-axis (as shown), the second beam 12 is located inside the first beam 11 and is spaced apart from the first beam 11, that is, there is a gap between the second beam 12 and the first beam 11.

[0063] The two ends of the flip plate 21 are rotatably connected to the second beam 12. The flip plate 21 is configured to rotate upward or downward about the connection between the flip plate 21 and the second beam 12. When the flip plate 21 is rotated upward to the horizontal closed position, the upper surface of the flip plate 21 is flush with the first beam. When the flip plate 21 is rotated downward to the vertical open position, the side of the flip plate 21 closer to the first beam 11 rotates to the top of the first beam 11 and the side of the flip plate 21 away from the first beam 11 rotates to the bottom of the first beam 11.

[0064] Therefore, it can be seen that the second beam 12 can serve as the rotation fulcrum of the flip plate 21.

[0065] like Figure 2 , Figure 4 and Figure 5As shown, the two ends of the first flip plate 21a are rotatably connected to the second beam 12 at pivot axis a1, the two ends of the second flip plate 21b are rotatably connected to the second beam 12 at pivot axis a2 (not shown), the two ends of the third flip plate 21c are rotatably connected to the second beam 12 at pivot axis a3, and the two ends of the fourth flip plate 21d are rotatably connected to the second beam 12 at pivot axis a4. In other words, the first flip plate 21a, the second flip plate 21b, the third flip plate 21c, and the fourth flip plate 21d can rotate about pivot axis a1, pivot axis a2, pivot axis a3, and pivot axis a4, respectively. Figure 4 As shown, the fourth flip plate 21d can be rotated downwards about the pivot axis a4 to reach the vertical open position; as Figure 2 As shown, the fourth flip plate 21d can rotate upwards about the pivot axis a4 to reach the horizontal closed position.

[0066] When one of the flip panels 21 is in the vertical open position, for example Figure 4 As shown, when the fourth flip plate 21d is rotated to the vertical open position, the fourth flip plate 21d no longer supports the user's back. In other words, the area on the user's back corresponding to the fourth flip plate 21d (e.g., the area on the user's back near the buttocks and right leg) can be exposed; or for example... Figure 8 As shown, when the third flip plate 21c is rotated to the vertical open position, it no longer supports the user's back. In other words, the area on the user's back corresponding to the third flip plate 21c (e.g., the area near the buttocks and left leg) is exposed. Therefore, the cleaning mechanism 3 can move to the cleaning position corresponding to the fourth flip plate 21d or the cleaning position corresponding to the third flip plate 21c to clean this area on the user's back. Understandably, at this time, the other three flip plates are in the horizontal closed state, thus still providing support for the user and eliminating the risk of the user tipping over.

[0067] Please continue reading Figure 2 and Figure 4 The bed board mechanism 2 also includes an arc-shaped connecting plate 22 and a tilting actuator 23. The arc-shaped connecting plate 22 is located between the first beam 11 and the second beam 12, and one end of the arc-shaped connecting plate 22 is rotatably connected to the side of the tilting plate 21 near the first beam 11. The tilting actuator 23 is fixedly installed inside the outer frame 1 and is rotatably connected to the other end of the arc-shaped connecting plate 22.

[0068] The arc-shaped connecting plate 22 is configured to extend from between the first beam 11 and the second beam 12 of the outer frame 1 under the drive of the flipping driver 23, thereby causing the flipping plate 21 to rotate downward to a vertical open position; or to return from between the first beam 11 and the second beam 12 of the outer frame 1 under the drive of the flipping driver 23, thereby causing the flipping plate 21 to rotate upward to a horizontal closed position.

[0069] The arc-shaped connecting plate 22 and the flip driver 23 are respectively arranged in a one-to-one correspondence with the flip plate 21, that is, each flip plate 21 is equipped with an arc-shaped connecting plate 22 and a flip driver 23.

[0070] like Figure 8 As shown, for the first flip plate 21a, the upper end of the arc-shaped connecting plate 22 is rotatably connected to the flip plate connecting plate 24 connected to the first flip plate 21a via a pivot a1, and the lower end of the arc-shaped connecting plate 22 is rotatably connected to the flip driver 23 via a pivot b1; as Figure 2 and Figure 4 As shown, for the third flip plate 21c, the upper end of the arc-shaped connecting plate 22 is rotatably connected to the flip plate connecting plate 24 connected to the third flip plate 21c via pivot a3, and the lower end of the arc-shaped connecting plate 22 is rotatably connected to the flip driver 23 via pivot b3; for the fourth flip plate 21d, the upper end of the arc-shaped connecting plate 22 is rotatably connected to the flip plate connecting plate 24 connected to the fourth flip plate 21d via pivot a4, and the lower end of the arc-shaped connecting plate 22 is rotatably connected to the flip driver 23 via pivot b3.

[0071] Therefore, it can be seen that for the second flip plate 21b, the upper end of the arc-shaped connecting plate 22 is rotatably connected to the flip plate connecting plate 24 connected to the second flip plate 21b via the pivot a2 (not shown), and the lower end of the arc-shaped connecting plate 22 is rotatably connected to the flip driver 23 via the pivot b2 (not shown).

[0072] The flipping actuator 23 can be an electric actuator or a hydraulic actuator, which can achieve the rotation of the flipping plate 21 by pushing and pulling the arc-shaped connecting plate 22.

[0073] Specifically, such as Figure 2 and Figure 4 For example, when the fourth flip plate 21d needs to be rotated, the flip driver 23 corresponding to the fourth flip plate 21d extends, thereby pushing the arc-shaped connecting plate 22 connected to it to extend out from between the first beam 11 and the second beam 12. Then, the upper end of the arc-shaped connecting plate 22 and the fourth flip plate 21d rotate relative to each other about the pivot axis c4. At the same time, the fourth flip plate 21d rotates relative to the second beam 12 about the pivot axis a4, that is, the fourth flip plate 21d rotates clockwise from... Figure 2 Rotate to the horizontal closed position shown. Figure 4The vertical opening position is shown. Alternatively, for example, when it is necessary to rotate the third flip plate 21c, the flip driver 23 corresponding to the third flip plate 21c extends, thereby pushing the arc-shaped connecting plate 22 connected to it to extend out from between the first beam 11 and the second beam 12. Then, the upper end of the arc-shaped connecting plate 22 and the third flip plate 21c rotate relative to each other about the pivot axis c3. At the same time, the third flip plate 21c rotates relative to the second beam 12 about the pivot axis a3, that is, the third flip plate 21c rotates counterclockwise from... Figure 2 Rotate to the horizontal closed position shown. Figure 8 The vertical open position is shown. The opening and closing of the first flip plate 21a and the third flip plate 21c are the same, and will not be described again here.

[0074] Please continue reading Figure 2 The arc-shaped connecting plate 22 is constructed as an arc-shaped structure that protrudes in a direction away from the second beam 12. When the arc-shaped connecting plate 22 extends or retracts from between the first beam 11 and the second beam 12 of the outer frame 1, the outer side of the arc-shaped connecting plate 22 remains in contact with the inner edge of the first beam 11.

[0075] As described above, there is a gap between the first beam 11 and the second beam 12, allowing the arc-shaped connecting plate 22 to move within this gap. Therefore, the second beam 12 also serves to constrain the movement trajectory of the arc-shaped connecting plate 22. The arc-shaped connecting plate 22 is constructed in an arc shape, ensuring that its outer side remains in contact with the inner edge of the first beam 11 when extending or retracting, thus guaranteeing a stable movement trajectory. Furthermore, it allows the arc-shaped connecting plate 22 to rotate at a relatively uniform speed, preventing excessively rapid rotation that could injure the user's back.

[0076] In each bed board mechanism 2, one of the flip-up plates 21 is in the vertically open position, while the other flip-up plates are simultaneously in the horizontally closed position. As described above, since the flip-up plate 21 can support the user's back when it is in the horizontally closed position, if all the flip-up plates 21 are rotated to the vertically open position, such as Figure 6A As shown, the user will lose support and fall at this time. Therefore, to avoid this situation, only one flip panel should be in the vertical open position at a time, while the other flip panels are in the horizontal closed position at the same time.

[0077] like Figure 2 As shown, when the third flip plate 21c and the fourth flip plate 21d are in the horizontal closed position, their upper surfaces are flush with the upper surface of the first beam 11; understandably, when the first flip plate 21a and the second flip plate 21b are in the horizontal closed position, their upper surfaces are flush with the upper surface of the first beam 11; thus, the entire surface of the bath bed has no protruding parts to avoid injuring the user.

[0078] like Figure 6C As shown, when the third flip plate 21c is in the vertically open position, since it rotates relative to the second beam 12, and the second beam 12 is located below the first beam 11 in the Z-axis direction, after the third flip plate 21c rotates, the side of the third flip plate 21c closest to the first beam 11 rotates to above the first beam 11, and the side of the third flip plate 21c furthest from the first beam 11 rotates to below the first beam 11. Similarly, when the fourth flip plate 21d is in the vertically open position, since it rotates relative to the second beam 12, and the second beam 12 is located below the first beam 11 in the Z-axis direction, after the fourth flip plate 21d rotates, the side of the fourth flip plate 21d closest to the first beam 11 rotates to above the first beam 11, and the side of the fourth flip plate 21d furthest from the first beam 11 rotates to below the first beam 11. The first flip plate 21a and the second flip plate 21b have similar effects.

[0079] It should be noted that, Figure 6A , Figure 6C and Figure 6C Although all the flip plates 21 are in the vertically open position, this is only for illustrative purposes, to better show the structure of the cleaning mechanism 3. In use, only one flip plate 21 is in the vertically open position, while the other three flip plates 21 are in the horizontally closed position.

[0080] Understandably, the purpose of providing multiple flip-up panels 21 in this invention is that each flip-up panel 21 corresponds to a different area of ​​the user's back. Therefore, by opening different flip-up panels 21 in turn, different areas of the user's back can be exposed respectively, while the flip-up panels 21 that are not opened can continue to provide support. Combined with the mobile washing mechanism 3, the entire back of the user can be washed without moving the user. Therefore, the bathing bed of this invention can greatly assist disabled persons in washing. The user's back in this invention includes the entire back, legs, and feet.

[0081] like Figure 16A and Figure 16B As shown, at this time, the first flip plate 21a rotates to the vertical open position, while the second flip plate 21b, the third flip plate 21c, and the fourth flip plate 21d are all in the horizontal closed position. Therefore, the area on the user's back corresponding to the first flip plate 21a near the right hand and shoulder is exposed, and the cleaning mechanism 3 moves to the cleaning position corresponding to this area, thereby cleaning this area on the user's back.

[0082] like Figure 17A and Figure 17BAs shown, at this time, the second flip plate 21b rotates to the vertical open position, while the first flip plate 21a, the third flip plate 21c, and the fourth flip plate 21d are all in the horizontal closed position. Therefore, the area on the user's back corresponding to the second flip plate 21b near the left hand and shoulder is exposed, and the cleaning mechanism 3 moves to the cleaning position corresponding to this area, thereby cleaning this area on the user's back.

[0083] like Figure 18A and Figure 18B As shown, at this time, the third flip plate 21c rotates to the vertical open position, while the first flip plate 21a, the second flip plate 21b, and the fourth flip plate 21d are all in the horizontal closed position. Therefore, the area on the user's back corresponding to the third flip plate 21c, near the left leg and buttocks, is exposed. The cleaning mechanism 3 moves to the cleaning position corresponding to this area, thereby allowing the cleaning of this area on the user's back.

[0084] like Figure 19A and Figure 19B As shown, at this time, the fourth flip plate 21d rotates to the vertical open position, while the first flip plate 21a, the second flip plate 21b, and the third flip plate 21c are all in the horizontal closed position. Therefore, the area on the user's back corresponding to the fourth flip plate 21d near the right leg and buttocks is exposed, and the cleaning mechanism 3 moves to the cleaning position corresponding to this area, thereby allowing the cleaning of this area on the user's back.

[0085] Therefore, it can be seen that when the first flip plate 21a, the second flip plate 21b, the third flip plate 21c, and the fourth flip plate 21d are rotated to their vertical open positions in sequence, the cleaning mechanism 3 can move to the cleaning position accordingly to perform cleaning. After all the flip plates 21 have performed the action of rotating to their vertical open positions once, the cleaning mechanism 3 can complete the cleaning of the user's entire back. During this process, there is no need to move the user or make them turn to the side or over, which greatly facilitates the cleaning work for disabled people who are bedridden for a long time. In addition, when one of the flip plates 21 is open for cleaning, the other flip plates are still in the closed position, which can still support the user. Since the support area occupied by one flip plate 21 is only 1 / 4, only one flip plate 21 is rotated to open each time, while the other flip plates 21 are in the closed position, which can ensure safe support for the user without worrying about the user falling over.

[0086] Understandably, the number of flip plates 21 can also be 6 or more, and this utility model does not limit this.

[0087] like Figures 9-15As shown, the cleaning mechanism 3 includes a cleaning head 34 and a first drive mechanism 31 connected to the cleaning head 34. The first drive mechanism 31 is connected to the outer frame 1 and is used to drive the cleaning head 34 along the height direction of the outer frame 1 (e.g., ...). Figure 2 The movement is along the Z-axis direction shown. When the flip plate 21 is in the vertical open position, the first drive mechanism 31 causes the cleaning head 34 to move upward along the height direction of the outer frame 1 to the cleaning position corresponding to the flip plate 21; when the flip plate 21 is in the horizontal closed position, the first drive mechanism 31 causes the cleaning head 34 to move downward along the height direction of the outer frame 1 to the storage position.

[0088] The first drive mechanism 31 is constructed as a push rod mechanism, a hydraulic mechanism, a lead screw mechanism, or a belt drive mechanism.

[0089] like Figure 9 As shown, the first driving mechanism 31 is a push rod mechanism as an example for explanation.

[0090] The first drive mechanism 31 includes a lifting push rod 311, a lifting bracket 312, a first slide rail 313, and a first slider 314. A cleaning mechanism bracket 14 is provided at the bottom of the outer frame 1, and the lifting push rod 311 can be fixed on the cleaning mechanism bracket 14.

[0091] The lifting push rod 311 is connected to the lifting bracket 312. Specifically, there can be four lifting push rods 311. The four lifting push rods 311 support the lifting bracket 312 at the four corners at the bottom of the lifting bracket 312. Therefore, when the lifting bracket 312 is raised, it can rise and fall stably.

[0092] In addition, a first slide rail 313 is provided on the outer frame 1, extending along the height direction of the outer frame 1. A first slider 314 is slidably provided on the first slide rail 313, and the first slider 314 is connected to the lifting bracket 312. When the lifting push rod 311 extends, it can push the lifting bracket 312 to move on the first slide rail 313. The first slide rail 313 can ensure the movement trajectory of the lifting push rod 311, so that the lifting push rod 311 can move more stably.

[0093] like Figure 7 As shown, the first drive mechanism 31 is located inside the outer frame 1 and below each flip plate 21, so the washing head 34 above the first drive mechanism 31 will not contact the user's back. Figure 8 As shown, when one of the flip plates 21, such as the first flip plate 21a, rotates to the vertical open position, as... Figure 9 and Figure 10The first drive mechanism 31 can drive the cleaning head 34 to move upward until the cleaning head 34 can contact the user's back, so that the area on the user's back corresponding to the first flip plate 21a can be cleaned.

[0094] like Figure 7 As shown, the first drive mechanism 31 is located inside the outer frame 1 and below each flip plate 21, so the washing head 34 above the first drive mechanism 31 will not contact the user's back. Figure 18B As shown, when one of the flip plates 21, such as the third flip plate 21c, is rotated to the vertical open position, the first drive mechanism 31 can drive the cleaning head 34 to move upward until the cleaning head 34 can contact the user's back, so that the area on the user's back corresponding to the third flip plate 21c can be cleaned.

[0095] Therefore, it can be understood that the first drive mechanism 31 is used to adjust the height of the cleaning head 34, so that it moves upward to a cleaning position that can reach the user, or moves downward to a storage position located below the flip plate 21.

[0096] The cleaning mechanism 3 also includes a second drive mechanism 32 and a third drive mechanism 33. The cleaning head 34 is connected to the first drive mechanism 31 through the second drive mechanism 32 and the third drive mechanism 33. The third drive mechanism 33 is connected to the cleaning head 34, and the second drive mechanism 32 is connected to both the third drive mechanism 33 and the first drive mechanism 31. The second drive mechanism 32 is used to move the third drive mechanism 33 and the cleaning head 34 along the width direction of the outer frame 1, and the third drive mechanism 33 is used to move the cleaning head 34 along the length direction of the outer frame 1.

[0097] The second drive mechanism 32 is constructed as a belt drive mechanism, a lead screw mechanism, or a gear drive mechanism, and the third drive mechanism 33 is constructed as a belt drive mechanism, a lead screw mechanism, or a gear drive mechanism.

[0098] like Figures 11-15 As shown, the second drive mechanism 32 is a lead screw mechanism and the third drive mechanism 33 is a belt drive mechanism, which will be used as examples for explanation.

[0099] like Figure 11 , Figure 14 and Figure 15 As shown, the second drive mechanism 32 includes a slide table, which includes a slide table bracket 321, a second slide rail 322, a second slider 323, a lead screw motor 324, a lead screw 325, and a lead screw nut 326. The slide table 321 is mounted on the lifting bracket 312, so the second drive mechanism 32 can be driven to move up and down together when the lifting bracket 312 is raised and lowered.

[0100] A second slide rail 322 and a lead screw 325 are arranged side by side on the slide table 321. A lead screw nut 326 is threaded through the lead screw 325. The lower side of the lead screw nut 326 is fixedly connected to a second slider 323, and the lower end of the second slider 323 is movably mounted on the second slide rail 322. The lead screw nut 326 at the upper end of the second slider 323 is connected to a third drive mechanism 33. The end of the lead screw 325 is connected to a lead screw motor 324. When the lead screw motor 324 drives the lead screw 325 to rotate, the second slider 323 moves on the lead screw 325, thereby driving the third drive mechanism 33 and the cleaning head 34 to move. The second slide rail 322 can constrain its movement trajectory, thereby ensuring stable movement.

[0101] Since both the second slide rail 322 and the lead screw 325 extend along the width direction of the outer frame 1, when the lead screw 325 is driven to rotate, the lead screw nut 326 on it can drive the third drive mechanism 33 and the cleaning head 34 to move along the extension direction of the lead screw 325, that is, the width direction of the outer frame 1.

[0102] A second limiting device may be provided on the second slide rail 322 or the lead screw 325 to limit the maximum displacement of the lead screw nut 326 (or the second slider 323). When the lead screw nut 326 (or the second slider 323) moves to its maximum displacement, the second limiting device is triggered and sends a signal to the lead screw motor 324. After receiving the signal, the lead screw motor 324 stops rotating, thereby stopping the drive of the lead screw nut 326 (or the second slider 323) to continue moving.

[0103] Therefore, it can be understood that the second drive mechanism 32 is used to adjust the position of the cleaning head 34 in the width direction of the outer frame 1. That is, the second drive mechanism 32 can move the cleaning head 34 from the position corresponding to the first flip plate 21a to the position corresponding to the second flip plate 21b, and vice versa. Therefore, when the first flip plate 21a is rotated to the vertical open position, the second drive mechanism 32 can move the cleaning head 34 to the position corresponding to the first flip plate 21a, thereby cleaning the corresponding area of ​​the user's back; after cleaning, the first flip plate 21a is rotated to the horizontal closed position, and the second flip plate 21b is rotated to the vertical open position, then the second drive mechanism 32 can move the cleaning head 34 to the position corresponding to the second flip plate 21b, thereby cleaning the corresponding area of ​​the user's back.

[0104] Alternatively, the second drive mechanism 32 can move the cleaning head 34 from the position corresponding to the third flip plate 21c to the position corresponding to the fourth flip plate 21d, and vice versa. Therefore, when the third flip plate 21c rotates to the vertical open position, the second drive mechanism 32 can move the cleaning head 34 to the position corresponding to the third flip plate 21c, thereby cleaning the corresponding area on the user's back; after cleaning, the third flip plate 21c rotates to the horizontal closed position, and the fourth flip plate 21d rotates to the vertical open position, then the second drive mechanism 32 can move the cleaning head 34 to the position corresponding to the fourth flip plate 21d, thereby cleaning the corresponding area on the user's back.

[0105] The number of second drive mechanisms 32 can be two or more. For example... Figure 6A As shown, there are two second drive mechanisms 32, which are spaced apart along the length of the outer frame 1 to ensure better support for the third drive mechanism 33.

[0106] like Figure 12 , Figure 13 , Figure 14 and Figure 15 As shown, the third drive mechanism 33 includes a synchronous belt 331, a synchronous pulley 332, a synchronous belt motor 333, a slide table bracket 334, a third slide rail 335, and a third slider 336.

[0107] The synchronous pulleys 332 are respectively disposed at both ends of the synchronous belt 331, and the rotation of the synchronous pulleys 332 can move the synchronous belt 331. More specifically, the synchronous pulleys 332 are gear structures with teeth, and the inner side of the synchronous pulleys 332 has corresponding teeth. Therefore, the synchronous pulleys 332 can mesh with the inner side of the synchronous belt 331, thereby driving it to move.

[0108] The synchronous pulley 332 is supported on the nut 326 of the second drive mechanism 32 by the slide bracket 334, so when the nut 326 moves, it can drive the third drive mechanism 33 to move as a whole.

[0109] There can be two or more third sliders 336, each connected to one side of the timing belt 331, thereby enabling the third slider 336 to move. The third slider 336 is mounted on the third slide rail 335 and can move along the third slide rail 335, which can constrain its movement trajectory. The third slider 336 is connected to the cleaning head 34, so that when it moves along the third slide rail 335, it can drive the cleaning head 34 to move together.

[0110] Understandably, when the timing pulley 332 rotates, the timing belt 331 can drive the third slider 336 and the cleaning head 34 to move in the direction toward the user's head. When the timing pulley 332 rotates in the opposite direction, the timing belt 331 can drive the third slider 336 and the cleaning head 34 to move in the direction toward the user's feet.

[0111] Since the timing pulleys 332 are spaced apart along the length of the outer frame 1, that is, the timing belt 331 extends along the length of the outer frame 1, when the third slider 336 connected to the timing belt 331 moves, it can drive the cleaning head 34 to move along the length of the outer frame 1.

[0112] In addition, a limit device is provided on the synchronous pulley 332. The limit device can be a mechanical limit device or an electronic limit device, which is used to stop the synchronous pulley 332 from rotating when the third slider 336 moves to the limit position, thereby ensuring a safe distance between the third slider 336 and the synchronous pulley 332.

[0113] like Figure 12 As shown, the cleaning head 34 includes a cleaning bracket 341 and a brush head 342. The cleaning bracket 341 is connected to two third sliders 336 respectively. The brush head 342 is positioned above the cleaning bracket 341 and is used to scrub the user's back. The cleaning bracket 341 is connected to the third sliders 336, meaning the cleaning head 34 is supported on the third sliders 336 via the cleaning bracket 341. Therefore, when the third sliders 336 move, they can drive the entire cleaning head 34 to move.

[0114] The cleaning bracket 341 is equipped with at least one brush head 342, such as Figure 13 As shown, the cleaning bracket 341 is equipped with three brush heads 342. Each brush head 342 can be connected to its own motor to drive it to rotate independently, or the three brush heads 342 can be connected to the same motor to drive them to rotate together. Understandably, more brush heads 342 can be installed on the cleaning bracket 341.

[0115] In some alternative embodiments, an infrared sensor may be provided on the brush head 342. When it detects contact with the user's back, it may send a signal to the lifting push rod 311 of the first drive mechanism 31. After receiving the signal, the lifting push rod 311 of the first drive mechanism 31 will stop driving the lifting bracket 312 to rise.

[0116] In some optional embodiments, a first limiting device is provided on the first slide rail 313 or the outer frame 1 to limit the maximum displacement of the first slider 314. Since the brush head 342 is used to clean the user's back, the height at which the brush head 342 moves from the storage position to the cleaning position is constant. Therefore, the first limiting device can be set at the corresponding height position of the first slide rail 313 or the outer frame 1 to ensure the maximum displacement of the first slider 314. When the first slider 314 moves to this position, the first limiting device is triggered, which sends a signal to the lifting push rod 311 of the first drive mechanism 31. After receiving the signal, the lifting push rod 311 of the first drive mechanism 31 will stop driving the lifting bracket 312 to rise.

[0117] In addition, a nozzle can be installed in the brush head 342, through which cleaning water and cleaning solution can be sprayed onto the user for a more thorough cleaning. The nozzle can be connected to a water pump in the outer frame 1, through which the water pump delivers cleaning water and cleaning solution to the nozzle.

[0118] In some alternative embodiments, the cleaning mechanism 3 can move accordingly depending on whether each flip plate 21 is open. In this embodiment, a sensor switch (e.g., a contact switch) can be installed on the second beam 12 at a position corresponding to each flip plate 21. When a flip plate 21 rotates to the vertical open position, the corresponding sensor switch is triggered, sending a signal that the flip plate 21 is open to the cleaning mechanism 3. The first drive mechanism 31, the second drive mechanism 32, and the third drive mechanism 33 in the cleaning mechanism 3 then perform corresponding actions, thereby moving the cleaning mechanism 3 to the position corresponding to the open flip plate 21 to perform the cleaning action. When each flip plate 21 is in the horizontal closed position, the corresponding sensor switch is not triggered, and the cleaning mechanism 3 does not receive a signal that the flip plate 21 is open, thus the cleaning mechanism 3 will not move to the cleaning position.

[0119] Therefore, it is understandable that in this solution, the flip plate 21 at a certain position can be set to open or close as needed, so that the area corresponding to the flip plate 21 can be cleaned in a focused manner.

[0120] In some alternative embodiments, the cleaning mechanism 3 can move along a predetermined path. For example, the cleaning mechanism 3 first moves to the cleaning position corresponding to the first flip plate 21a and performs the cleaning action; then it moves to the cleaning position corresponding to the second flip plate 21b and performs the cleaning action; then it moves to the cleaning position corresponding to the third flip plate 21c and performs the cleaning action; finally it moves to the cleaning position corresponding to the fourth flip plate 21d and performs the cleaning action. After all the cleaning actions at the above four positions are completed, it can return to the storage position.

[0121] Furthermore, the first drive mechanism 31, the second drive mechanism 32, and the third drive mechanism 33 do not operate simultaneously. That is, each drive mechanism adjusts the relative position of the cleaning head 34 and the outer frame 1 separately to ensure safety. Therefore, when the lifting push rod 311 of the first drive mechanism 31 is activated, the lead screw motor 324 of the second drive mechanism 32 and the synchronous pulley 332 of the third drive mechanism 33 are both locked. Similarly, when the lead screw motor 324 of the second drive mechanism 32 or the synchronous pulley 332 of the third drive mechanism 33 is activated, the lifting push rod 311 of the first drive mechanism 31 is locked.

[0122] In addition, such as Figure 2 As shown, one or more casters 13 are provided at the four corners of the bottom of the outer frame 1. The casters 13 can be used to push the outer frame 1 into a room suitable for bathing, so that the user on it can be cleaned.

[0123] The intelligent back-cleaning bathing bed of this utility model includes the following steps:

[0124] 100: One of the flip panels 21 is rotated relative to the outer frame 1 to a vertical open position.

[0125] 200: The cleaning mechanism 3 moves to the cleaning position corresponding to the flip plate 21 and performs the action of cleaning the back.

[0126] 300: Repeat step 100 until the cleaning mechanism 3 has completed the back cleaning action at the cleaning position corresponding to each flip plate 21.

[0127] 400: Cleaning mechanism 3 moves to the storage position.

[0128] 500: All flip panels 21 are rotated relative to the outer frame 1 to the horizontal closed position.

[0129] In one specific implementation, please refer to Figures 16A-19B And please combine Figure 1 and Figure 7 In the initial state, the first flip plate 21a, the second flip plate 21b, the third flip plate 21c, and the fourth flip plate 21d are all in a horizontal closed position. The user lies flat on each flip plate 21, and understandably, the user's back is divided into four areas by each flip plate 21. In the initial state, the cleaning mechanism 3 is located inside the outer frame 1 and is in a stowed position.

[0130] like Figure 16A and Figure 16B As shown, first rotate the first flip plate 21a to the vertical open position. Please refer to... Figure 5The flipping actuator 23 corresponding to the first flipping plate 21a extends, thereby pushing the arc-shaped connecting plate 22 connected to it to extend out from between the first beam 11 and the second beam 12. Then, the upper end of the arc-shaped connecting plate 22 and the first flipping plate 21a rotate relative to each other about the pivot axis c1. At the same time, the first flipping plate 21a rotates relative to the second beam 12 about the pivot axis a1. That is, the first flipping plate 21a can extend from between the first beam 11 and the second beam 12. Figure 1 Rotate to the horizontal closed position shown. Figure 16A and Figure 16B The vertical opening position is shown.

[0131] like Figure 16B As shown, after the first flip plate 21a rotates to the vertical open position, the first drive mechanism 31 is activated. The lifting push rod 311 extends, thereby pushing the lifting bracket 312 to rise. Then, the second drive mechanism 32, the third drive mechanism 33 and the cleaning head 34 on the lifting bracket 312 rise until the brush head 342 of the cleaning head 34 contacts the user's back, so that the user's back can be cleaned.

[0132] During cleaning, the lead screw motor 324 of the second drive mechanism 32 rotates forward or reverse, causing the lead screw nut 326 to drive the third drive mechanism 33 and the cleaning head 34 to move on the second slide rail 322, thereby adjusting the position of the cleaning head 34 in the width direction of the outer frame 1. Furthermore, the forward or reverse rotation of the synchronous pulley 332 of the third drive mechanism 33 causes the third slider 336 to drive the cleaning head 34 to move on the third slide rail 335, thereby adjusting the position of the cleaning head 34 in the length direction of the outer frame 1. This allows the cleaning head 34 to clean various areas of the user's back corresponding to the first flip plate 21a.

[0133] In one embodiment, the storage position of the cleaning mechanism 3 corresponds to the lower part of the first flip plate 21a. Therefore, after the first flip plate 21a is rotated to the vertical open position, the first drive mechanism 31 can first drive the second drive mechanism 32, the third drive mechanism 33 and the cleaning head 34 to rise.

[0134] Understandably, the storage position of the cleaning mechanism 3 can also be in other positions. In this case, the second drive mechanism 32 and / or the third drive mechanism 33 need to drive the cleaning head 34 to move below the opened flip plate 21 first, and then the first drive mechanism 31 drives the second drive mechanism 32, the third drive mechanism 33 and the cleaning head 34 to rise.

[0135] After the area corresponding to the first flip plate 21a is cleaned, rotate the first flip plate 21a to the horizontal closed position. Please refer to... Figure 5The flipping actuator 23 corresponding to the first flipping plate 21a retracts, thereby pushing the arc-shaped connecting plate 22 connected to it back between the first beam 11 and the second beam 12. Then, the upper end of the arc-shaped connecting plate 22 and the first flipping plate 21a rotate relative to each other about the pivot axis c1. At the same time, the first flipping plate 21a rotates relative to the second beam 12 about the pivot axis a1. That is, the first flipping plate 21a can move from... Figure 16A and Figure 16B Rotate the vertical opening position shown to Figure 1 The horizontal closing position is shown.

[0136] like Figure 17A and Figure 17B As shown, after the first flip plate 21a is rotated to the horizontal closed position, the second flip plate 21b is rotated to the vertical open position. Its rotation method is the same as that of the first flip plate 21a, and will not be described again here.

[0137] When the second flip plate 21b rotates to the vertical open position, the lead screw motor 324 of the second drive mechanism 32 rotates, causing the lead screw nut 326 to drive the third drive mechanism 33 and the cleaning head 34 to move on the second slide rail 322. The cleaning head 34 can then move from the cleaning position corresponding to the first flip plate 21a to the cleaning position corresponding to the second flip plate 21b and perform the cleaning action.

[0138] During cleaning, the position of the cleaning head 34 in the width and length directions of the outer frame 1 is adjusted by the second drive mechanism 32 and the third drive mechanism 33, so that the cleaning head 34 can clean various parts of the user's back area corresponding to the second flip plate 21b.

[0139] After the area corresponding to the second flip plate 21b is cleaned, rotate the second flip plate 21b to the horizontal closed position.

[0140] like Figure 18A and Figure 18B As shown, after the second flip plate 21b is rotated to the horizontal closed position, the third flip plate 21c is rotated to the vertical open position. Its rotation method is the same as that of the first flip plate 21a, and will not be described again here.

[0141] When the third flip plate 21c rotates to the vertical open position, the synchronous pulley 332 of the third drive mechanism 33 rotates, causing the third slider 336 to drive the cleaning head 34 to move. The cleaning head 34 can then move from the cleaning position corresponding to the second flip plate 21b to the cleaning position corresponding to the third flip plate 21c and perform the cleaning action.

[0142] During cleaning, the position of the cleaning head 34 in the width and length directions of the outer frame 1 is adjusted by the second drive mechanism 32 and the third drive mechanism 33, so that the cleaning head 34 can clean various parts of the user's back area corresponding to the third flip plate 21c.

[0143] After the area corresponding to the third flip plate 21c is cleaned, rotate the third flip plate 21c to the horizontal closed position.

[0144] like Figure 19A and Figure 19B As shown, after the third flip plate 21c is rotated to the horizontal closed position, the fourth flip plate 21d is rotated to the vertical open position. Its rotation method is the same as that of the first flip plate 21a, and will not be described again here.

[0145] When the fourth flip plate 21d rotates to the vertical open position, the lead screw motor 324 of the second drive mechanism 32 rotates, causing the lead screw nut 326 to drive the third drive mechanism 33 and the cleaning head 34 to move on the second slide rail 322. Then the cleaning head 34 can move from the cleaning position corresponding to the third flip plate 21c to the cleaning position corresponding to the fourth flip plate 21d and perform the cleaning action.

[0146] During cleaning, the position of the cleaning head 34 in the width and length directions of the outer frame 1 is adjusted by the second drive mechanism 32 and the third drive mechanism 33, so that the cleaning head 34 can clean various parts of the user's back area corresponding to the fourth flip plate 21d.

[0147] After the cleaning head 34 cleans the back areas of the user corresponding to the four flip plates 21, the first drive mechanism 31 can drive the second drive mechanism 32, the third drive mechanism 33 and the cleaning head 34 to descend. The second drive mechanism 32 and the third drive mechanism 33 adjust the position of the cleaning head 34 in the width and length directions of the outer frame 1, so that it returns to the storage position below the first flip plate 21a, thereby ending the cleaning work.

[0148] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
