Description

Technical Field

[0001] This invention relates to the field of electric bed technology, and more specifically to a multifunctional electric bed. Background Technology

[0002] An electric bed is a single bed with an electric lifting function, and it is usually set up in places such as massage parlors. Electric beds also have a liftable backrest, so that users can lie half-reclined on the electric bed.

[0003] Chinese patent CN219680162U discloses an electric bed. It includes a fixed plate, a first bed board, a second bed board, and a third bed board. The first, second, and third bed boards are hinged together and located at the top of the fixed plate. The existing electric bed features hinged connections between the first, second, and third bed boards, driven by a first motor. Through the cooperation of the components, the bed can be transformed into a chair with adjustable range, making it more ergonomic and comfortable. A second motor drives and adjusts the support rods and support base, allowing for height adjustment to facilitate use by children or the elderly and prevent falls. Internal springs in the support rods provide cushioning, further enhancing comfort. Casters at the bottom of the support base provide support when the bed is placed low, facilitating transport.

[0004] However, in some massage parlors or bathhouses, customers will raise the backrest to make it easier to watch movies, etc. But when customers lie on an electric bed with the backrest raised, their center of gravity is raised, and their upper body may tilt against the backrest. If customers try not to tilt, they need to exert force, which is not comfortable and reduces the customer's experience. Summary of the Invention

[0011] Preferably, the pulling assembly includes a second pull rope, a winding section, and an acceleration assembly; the acceleration assembly consists of two gears, which are respectively connected to the tilting bed and the electric assembly, and the two gears mesh; the winding section is mounted on the gear of the electric assembly; when the tilting bed rotates, it drives the gear on the tilting bed to rotate, which in turn drives the gear on the electric assembly to rotate faster, thereby driving the winding section to rotate faster; the two ends of the second pull rope are respectively connected to the winding section and the support plate.

[0012] Preferably, the stabilizing mechanism includes a piston cylinder, a piston shaft, a circular tube, a switch assembly, and an adsorption assembly; the piston cylinder is mounted on a support frame; the large end of the piston shaft is sleeved inside the piston cylinder, and its small end is connected to the electric assembly; the two ends of the circular tube are connected to the switch assembly and the piston cylinder; the adsorption assembly is mounted at the bottom of the support frame and is connected to the switch assembly.

[0013] Preferably, the switching assembly includes a cylinder, a pull rope three, a blocking part, and a circular tube two; the two ends of the pull rope three are respectively connected to the tilting bed and the blocking part; the bottom and middle part of the cylinder are respectively connected to the circular tube one and the circular tube two; the blocking part is elastically connected inside the cylinder; the two ends of the circular tube two are respectively connected to the cylinder and the adsorption assembly; and a circular hole is opened at the top of the cylinder.

[0016] Compared with the prior art, the above-mentioned technical solution of the present invention has the following beneficial technical effects: When the second drive unit is activated, causing the tilting bed to rotate around the bed frame, one end of the pull rope is fixed to the bed frame, while the other end pulls the lifting part towards the rising part. The lifting part pushes the rising part upward, thereby causing the support plate to move upward via the lifting rod, separating the locking part from the tilting bed. Then, the elasticity of the lifting elastic element causes the support plate to move towards the center of the tilting bed. As the support plate moves, it pushes the support part upward. When the support plate contacts the sides of the customer's arms, the movement stops. At this point, due to the separation of the push rod and the locking plate, the elasticity of the second elastic element... The locking plate moves towards the support plate, while the L-rod pushes the push plate. Due to the contact between the push plate and the damping part, the moving speed of the locking plate slows down. When the support plate stops moving, its position is fully adaptive and adjusted according to the customer's body shape. Then, the locking plate moves to the locking part and locks it in place, thus positioning the adjusted support plate. This ensures that when the flip bed is raised, the support plate adaptively supports both sides of the customer, preventing a decrease in comfort due to lack of support when the flip bed is raised.

[0017] When the drive unit is activated and the bed is raised, the piston shaft rises within the piston cylinder, pushing the cavity inside the piston cylinder into the cylinder. If the bed is in a flipped-over state at this time, the pull rope three moves the blocking part upward, blocking the circular hole at the top of the cylinder. At this time, the cavity inside the piston cylinder enters the piston cylinder along the cylinder and the circular tube, causing the piston shaft to descend. The piston shaft descends and the circular plate blocks the connection between the vent and the negative pressure adsorption part, causing the negative pressure adsorption part to compress and contract towards the ground. At this time, the air inside the negative pressure adsorption part is discharged from the gap between the support frame and the bottom of the negative pressure adsorption part. Because the negative pressure adsorption part and the ground are in a negative pressure state, the negative pressure adsorption part cannot move without venting, thus preventing the support frame from moving. This strengthens the stability of the support frame when the bed is raised and the center of gravity of the flipped bed is at its highest, preventing the support frame from slipping on wet surfaces such as bathhouses, which could cause customers on the bed to lose their stability.

[0020] Example 1, as Figures 1-10 As shown, the present invention proposes a multifunctional electric bed, including a support frame 1, an electric component, and a tilting bed 7; the electric component is mounted on the support frame 1, the tilting bed 7 is mounted on the electric component, and is raised, lowered, and rotated by the electric component; it also includes: a limiting mechanism mounted on the tilting bed 7; and a stabilizing mechanism mounted on the support frame 1 to prevent the support frame 1 from moving; the limiting mechanism includes a blocking component, a limiting component, a lifting component, a positioning component, and a pulling component; the blocking component is mounted on the tilting bed 7; the limiting component is mounted inside the tilting bed 7 and lifts the blocking component during use; the lifting component is mounted inside the tilting bed 7 and lifts the limiting component; the positioning component is mounted inside the tilting bed 7 and positions the moved limiting component; the pulling component is mounted outside the tilting bed 7 and pulls the limiting component back to its original position; when the tilting bed 7 rotates, the limiting component is lifted upward by the lifting component and stops moving towards the center after being blocked, and the positioning component positions the moved limiting component.

[0021] The shielding assembly includes a spring sleeve 8, a rotating cylinder 9, and a support part 10. The rotating cylinder 9 is installed outside the tilting bed 7, and the support part 10 is installed on the rotating shaft of the rotating cylinder 9. The spring sleeve 8 is installed outside the rotating cylinder 9 and connected to the rotating shaft of the rotating cylinder 9 at its center. A rotating shaft is installed in the middle of the rotating cylinder 9. There are two rotating cylinders 9, which are respectively connected to the two sides of the tilting bed 7. The two sides of the support part 10 are respectively connected to the rotating shafts of the two rotating cylinders 9. A coil spring is installed in the middle of the spring sleeve 8, and the rotating shaft in the middle of the rotating cylinder 9 passes through the rotating cylinder 9 and the spring sleeve 8 and is connected to the coil spring. A support block is installed in the middle of the inner cavity of the tilting bed 7. The support block is fixedly connected to the middle of the support part 10, so that when the customer is placed on the support part 10, he / she can be supported by the support block.

[0022] The limiting assembly includes a guide groove 3, a lifting elastic element 11, a support plate 12, and a locking part 19. The guide groove 3 is formed on the inner wall of the tilting bed 7. The two sides of the lifting elastic element 11 are slidably connected to the guide groove 3 and the support plate 12, respectively. The locking part 19 is installed on the support plate 12 and inserted into the tilting bed 7. The lifting elastic element 11 is connected by an elastic element four and a sliding plate. The two ends of the elastic element four are connected to the sliding plate and the support plate 12, respectively. The sliding plate is slidably connected in the guide groove 3. A through hole is provided at the bottom of the tilting bed 7, and the locking part 19 is inserted into the through hole to limit the support plate 12.

[0023] The lifting assembly includes a lifting section 13, an elastic element 14, a lifting rod 15, a raising section 16, a pull rope 17, and a push rod 20. The two ends of the pull rope 17 are connected to an electric assembly and the lifting section 13, respectively. The two ends of the elastic element 14 are connected to a support frame 1 and the lifting section 13, respectively. The lifting rod 15 is slidably connected within a guide groove 3. The raising section 16 is mounted on the lifting rod 15 and located on the movement path of the lifting section 13. A support plate 12 is sleeved on the lifting rod 15. The push rod 20 is mounted on the lifting section 16. The part 13 is used to push the positioning component; when the tilting bed 7 is in a horizontal state, the push rod 20 pushes the snap plate 22, and the elastic element 21 is squeezed and contracted to store force; when the tilting bed 7 is tilted, the pull rope 17 pulls the lifting part 13 to move towards the lifting part 16, thereby lifting the lifting part 16 upward, and then the lifting part 16 drives the lifting rod 15 to rise; there are multiple guide grooves 3, and multiple guide grooves 3 are opened on the inner wall of the tilting bed 7, and the lifting rod 15 is slidably connected in two of the guide grooves 3.

[0024] The positioning assembly includes a second elastic element 21, a snap-fit ​​plate 22, an L-rod 23, a third elastic element 24, a push plate 25, and a damping part 26. The two ends of the second elastic element 21 are connected to the tilting bed 7 and the snap-fit ​​plate 22, respectively. The L-rod 23 is mounted on the snap-fit ​​plate 22. The two ends of the third elastic element 24 are connected to the tilting bed 7 and the push plate 25, respectively. The L-rod 23 pushes the push plate 25 as the snap-fit ​​plate 22 moves towards the center of the tilting bed 7. The damping part 26 is installed inside the tilting bed 7 and fits against the push plate 25. When the snap-fit ​​plate 22 is pushed towards the second elastic element 21, the second elastic element 21 is in a compressed, stored state. When the snap-fit ​​plate 22 moves towards the lifting part 13, it drives the L-rod 24... Rod 23 pushes push plate 25. At this time, elastic element 24 positions and guides push plate 25. Through the contact between push plate 25 and damping part 26, damping part 26 dampes push plate 25, slowing down the movement speed of locking plate 22. After support plate 12 moves to a position, locking plate 22 engages with locking part 19, limiting the position of support plate 12. When lifting part 13 drives push rod 20 to push locking plate 22 toward elastic element 21, rod 23 separates from push plate 25. Therefore, when locking plate 22 is pushed back to its original position, the movement speed is not slowed down by the damping between push plate 25 and damping part 26.

[0025] The pulling assembly includes a second pull rope 18, a winding rope section 27, and an acceleration assembly 41. The acceleration assembly 41 consists of two gears, which are respectively connected to the tilting bed 7 and the electric assembly, and the two gears mesh. The winding rope section 27 is mounted on the gear of the electric assembly. When the tilting bed 7 rotates, it drives the gear on the tilting bed 7 to rotate, which in turn drives the gear on the electric assembly to rotate faster, thus accelerating the rotation of the winding rope section 27. The two ends of the second pull rope 18 are respectively connected to the winding rope section 27 and the support plate 12. When the tilting bed 7 tilts upward, the large gear mounted on the tilting bed 7 drives the small gear mounted on the bed body 5, thereby causing the large gear to drive the small gear to rotate faster, and the small gear to drive the winding rope section 27 to rotate faster, thereby pulling the second pull rope 18. The second pull rope 18 is released into a loose state, and then the support plate 12 can move towards the middle of the tilting bed 7. When the tilting bed 7 tilts downward to reset, the winding rope section 27 rotates in the opposite direction, thereby causing the winding rope section 27 to pull the second pull rope 18 to retract and return to the rope section 27, thus pulling the support plate 12 to reset.

[0026] Example 2, as Figures 1-5 As shown, the multifunctional electric bed proposed in this invention, compared with Embodiment 1, has a stabilizing mechanism including a piston cylinder 28, a piston shaft 29, a circular tube 30, a switch assembly, and an adsorption assembly; the piston cylinder 28 is mounted on the support frame 1; the large end of the piston shaft 29 is sleeved inside the piston cylinder 28, and its small end is connected to the electric assembly; the two ends of the circular tube 30 are connected to the switch assembly and the piston cylinder 28 respectively; the adsorption assembly is mounted at the bottom of the support frame 1 and is connected to the switch assembly; when the support frame 1 rises, it drives the piston shaft 29 to rise inside the piston cylinder 28, pushing the air in the inner cavity of the piston shaft 29 into the circular tube 31.

[0027] The switching assembly includes a cylinder 31, a pull rope 32, a blocking part 33, and a circular tube 34. The two ends of the pull rope 32 are connected to the tilting bed 7 and the blocking part 33, respectively. The bottom and middle part of the cylinder 31 are connected to the circular tube 30 and the circular tube 34, respectively. The blocking part 33 is elastically connected inside the cylinder 31. The two ends of the circular tube 34 are connected to the cylinder 31 and the adsorption assembly, respectively. A circular hole is opened at the top of the cylinder 31. In the initial state, the pull rope 32 is in a loose state. When the support frame 1 rises, the pull rope 32 is tightened, and the blocking part 33 is also located at the bottom of the inner cavity of the cylinder 31. At this time, the air entering the cylinder 31 from the piston cylinder 28 will be discharged from the circular hole at the top of the cylinder 31. When the tilting bed 7 tilts upward, the pull rope 32 will be pulled to the circular hole by the tilting bed 7 and block the circular hole. At this time, the cylinder 31 is closed, and the air in the piston cylinder 28 will enter the piston cylinder 35 along the circular tube 34.

[0028] The adsorption assembly includes piston cylinder 2 35, spring 1 36, piston shaft 2 37, circular plate 38, negative pressure adsorption part 39, and ventilation cylinder 40; piston cylinder 2 35 is mounted on support frame 1 and its top end is connected to circular tube 2 34; the two ends of spring 1 36 are respectively connected to piston cylinder 2 35 and piston shaft 2 37; the bottom end of piston shaft 2 37 passes through piston cylinder 2 35 and connects to circular plate 38; ventilation cylinder 40 is sleeved on circular plate 38; negative pressure adsorption part 39 is installed at the bottom of ventilation cylinder 40 and is connected to ventilation cylinder 40; elastic element 1 14, elastic element 2 21, elastic element 3 24, and elastic element 4 are all composed of telescopic rod and spring 2, with spring 2 sleeved on the outer periphery of telescopic rod; and other forms of elastic elements can also be selected for elastic element 1 14, elastic element 2 21, elastic element 3 24, and elastic element 4.

[0029] The electric assembly includes drive device 1 2, rectangular frame 4, bed 5 and drive device 2 6; drive device 1 2 is installed at the bottom of support frame 1; the output shaft of drive device 1 2 is connected to rectangular frame 4; bed 5 is installed on rectangular frame 4; the two ends of drive device 2 6 are respectively connected to rectangular frame 4 and tilting bed 7; the two ends of pull rope 17 are respectively connected to bed 5 and lifting part 13; drive device 1 2 and drive device 2 6 are cylinders, but other drive devices can also be selected.

[0030] In summary, in this invention, when a customer lies on the bed frame 5 and the flip-up bed 7, the bed frame 5 can be raised by activating drive device 2 to adjust the customer's height for convenient service. Drive device 6 can be activated to flip the flip-up bed 7 upwards, allowing the customer to recline comfortably. When the flip-up bed 7 flips upwards, since the end of the pull rope 17 connected to the bed frame 5 is fixed, the pull rope 17 pulls the lifting part 13 towards the rising part 16, lifting the rising part 16 upwards. At this time, the lifting rod 15 lifts the support plate 12 upwards, simultaneously pushing the support part 10 upwards. However, since the middle of the support part 10 is connected to the support block inside the flip-up bed 7, only the two sides of the support part 10 are pushed upwards. When the support plate 12 moves the locking part 19 upwards, the locking part 19... After leaving the flipping bed 7, the limit on the support plate 12 is released. Then, the elasticity of the lifting elastic element 11 drives the support plate 12 to move towards the center of the flipping bed 7, so that the support plate 12 fits against the sides of the customer's arm after the support part 10 protrudes, and then stops moving. At this time, due to the elasticity of the separation elastic element 21 between the push rod 20 and the locking plate 22, the locking plate 22 moves towards the lifting part 16. At this time, due to the setting of the push plate 25, the L rod 23 will push the push plate 25 to move. Due to the damping of the push plate 25 and the damping part 26, the movement speed of the locking plate 22 is slow. After the support plate 12 is adjusted to the correct position, the locking plate 22 engages with the locking part 19, limiting and locking the position of the locking part 19, thereby limiting and locking the support plate 12 after it is adjusted to the correct position.

[0031] As the support frame 1 is raised, the tilting bed 7 tilts, and the pull rope 32 pulls the blocking part 33 to rise to the top of the cylinder 31, blocking the circular hole on the cylinder 31. Then, the bed body 5 rises, causing the piston shaft 29 to rise inside the piston cylinder 28, compressing the air inside the piston cylinder 28 into the piston cylinder 35, thereby causing the piston shaft 37 to descend. This, in turn, causes the circular plate 38 to seal the connection between the vent 40 and the negative pressure adsorption part 39, and presses the negative pressure adsorption part 39 down to the ground. After the negative pressure adsorption part 39 contacts the ground, it is continuously pressed down, and then the air inside the negative pressure adsorption part 39 is drawn out from the negative pressure adsorption part. Air is discharged through the gap between the attachment 39 and the ground, creating a negative pressure state between the negative pressure adsorption part 39 and the ground, thereby preventing the support frame 1 from moving. When the bed 5 descends, the air in the piston cylinder 2 35 is drawn back into the piston cylinder 1 28, or the tilting bed 7 is tilted downwards to reset, causing the round hole of the cylinder 31 to leak out, and the air in the piston cylinder 2 35 to be discharged. The elasticity of the spring 1 36 drives the piston shaft 2 37 to rise, thereby driving the circular plate 38 to the connection between the ventilation cylinder 40 and the negative pressure adsorption part 39, so that the air in the negative pressure adsorption part 39 is discharged from the connection between the ventilation cylinder 40 and the negative pressure adsorption part 39, thereby relieving the negative pressure state of the negative pressure adsorption part 39.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
