The other end of the double-headed motor is connected to the motor shaft, and a reciprocating screw is coaxially connected to the end of the motor shaft. The reciprocating screw and the end of the motor shaft are magnetically adsorbed by magnetic suction cups respectively.

[0012] Preferably, a bracket 2 is extended from the surface of the beam toward the angle disk, a sleeve with an open end is fixed to the surface of the bracket 2 opposite to the angle disk, and a bracket 4 is extended from the surface of the sleeve toward the reciprocating screw rod, and a camera is fixed inside the sleeve.

[0020] The medical bed capable of measuring the adjustable angle of the bed head of the present invention has the following advantages:

[0021] 1. A medical bed with a measurable headboard adjustment angle. When the headboard angle of the medical bed needs to be adjusted, the adjustment is controlled on the display screen, and then the electric push rod is operated. As the electric push rod runs, the output end of the electric push rod can be extended or shortened. After the length of the electric push rod changes, the push rod hinged at one end can be flipped with the connection on the beam as the axis, so that the top of the push rod pushes the headboard, and then the second push rod can move along the length direction of the slide rail to make the headboard complete the corresponding angle adjustment.

[0023] 3. A medical bed capable of measuring the adjustable angle of the headboard. When the double-headed motor is controlled by the processor, the double-headed motor generates vibrations, which are transmitted through the bed frame and can be sensed. At the same time, the reciprocating screw at one end of the double-headed motor rotates together. After the reciprocating screw rotates, the sleeve sleeved on its outer circumference slides to one side. When the sleeve slides, the rack drives the gear to rotate, and then the gear causes the upper meshing baffle 1 to open to one side. At the same time as the rack moves, the connecting rod drives baffle 2, so that baffle 2 and baffle 1 can move in opposite directions. When the eccentric block vibrates, baffle 2 and baffle 1 move open to facilitate the camera to shoot the corresponding angle. The adjusted angle can then be verified.

[0024] 4. A medical bed capable of measuring the adjustable angle of the headboard. When the baffle 2 at the sleeve opening is pushed to one side by the rack, the conductive block 2 on the baffle 2 can move toward the conductive block 1 and finally contact it. After the conductive block 2 and the conductive block 1 are in contact and conductive, the camera takes a picture, and then the image can be transmitted to the display screen, making it convenient for personnel to verify its angle.

DETAILED DESCRIPTION

[0038] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] like Figure 1-Figure 4 As shown, a medical bed capable of measuring and adjusting the headboard angle of the present invention comprises a bed frame 1 and footboards 16 fixedly connected at both ends of the bed frame 1. A footboard 11 and a headboard 12 are connected above the bed frame 1. Each footboard 11 and headboard 12 can be adjusted in angle via electric actuators 2 connected at the bottom. A display screen 161 is fixed to the surface of one of the footboards 16, which displays the adjustment status of the medical bed. The electric actuator 2 of the medical bed can be controlled by a central processing unit within the display screen 161, and the display screen 161 is electrically connected to the electric actuators 2. A base frame 13 is also connected below the headboard 12.

[0040] A crossbeam 14 runs across the inside of the bed frame 1 near the bottom of the headboard 12, and the overall rigidity of the bed frame 1 is fixed by the crossbeam 14. One end of the electric push rod 2 is connected to the bottom surface of the bed frame 1 through a pin, and the other end is connected to the headboard 12 through a push rod 21. The rotating shaft seat 121 fixedly connected on both sides of the bottom surface of the headboard 12 is connected to one end of the push rod 21 through a pin, and the end of the push rod 21 near the bottom is connected to the crossbeam 14 through a pin. Therefore, when the electric push rod 2 is running, one end of the electric push rod 2 pushes the push rod 21, and then the push rod 21 can rotate with the pin on the crossbeam 14 as a fulcrum, so that the top of the push rod 21 pushes the headboard 12 to adjust the angle.

[0041] like Figure 4-Figure 6As shown, brackets 141 are fixed to both sides of the crossbeam 14, forming a cross with the crossbeam 14. A rotating shaft 142 is fixed to the front side of bracket 141, through which one end of a top rod 15 for tilting support passes. A guide rail 144 is fixed above bracket 141. A top rod 122 is fixed to the bottom side of the headstock 12, and the other end of the top rod 122 slides inside the slide rail 144 via a roller. The end of the top rod 122 connected to the bottom side of the headstock 12 is hinged to the end of the top rod 15. When the angle of the headboard of the medical bed needs to be adjusted, the electric push rod 2 is operated. As the electric push rod 2 operates, the output end of the electric push rod 2 can be extended or shortened. After the length of the electric push rod 2 changes, the push rod 21 hinged at one end can be flipped using the connection on the crossbeam 14 as an axis, so that the top of the push rod 21 pushes the headboard 12. Then, the second push rod 122 can move along the length of the slide rail 144 to adjust the angle of the headboard 12. At the same time, the processor inside the display screen 161 controls the operation time of the electric push rod 2 to stop at the desired flip angle of the headboard 12.

[0042] like Figure 6 As shown, an angle disc 151 is fixed to the surface of the push rod 15, which is penetrated by the rotating shaft 142. The surface of the angle disc 151 is also distributed with corresponding scales. A pointer 143 extends downward from the outer circumference of the rotating shaft 142, and the surface of the pointer 143 is in contact with the surface of the angle disc 151. Therefore, when the headboard 12 is tilted and adjusted by the electric push rod 2, one end of the push rod 15 can rotate around the rotating shaft 142 as the center of the circle. As the rotating shaft 142 rotates, the angle disc 151 fixed to its surface can also rotate. Then, the scale on the surface of the angle disc 151 can be pointed by the pointer 143, and the tilt angle of the headboard can be further verified by the angle disc 151.

[0043] like Figure 6-Figure 7 As shown, a feedback mechanism is fixedly connected to one end of the bracket 141, and the feedback mechanism controls the camera 32 located opposite to the front of the angle plate 151 to take photos for verification.

[0044] The feedback mechanism includes a double-headed motor 4 capable of generating vibration. An eccentric weight 41 is fixedly connected to one output end of the double-headed motor 4. After the angle of the electric push rod 2 is adjusted, the processor within the display screen 161 activates the double-headed motor 4, generating vibrations through the eccentric weight 41. The vibrations are transmitted through the bed frame 1 and can be sensed. The operation of the double-headed motor 4 is controlled by the processor within the display screen 161.

[0045] At the same time, the feedback mechanism also includes a strobe light installed above the display screen 161. After the angle adjustment of the electric push rod 2 is completed, the processor inside the display screen 161 can make the strobe light flash, which can be perceived by the operator.

[0046] like Figure 7-11 As shown, bracket 141, located near the angle disc 151, is secured to bracket 145 at one end. Bracket 145 is L-shaped, and its distal end is fixedly connected to the end of the double-headed motor 4. The other end of the double-headed motor 4 is connected to a motor shaft 44. A reciprocating screw 42 is coaxially connected to the end of the motor shaft 44. The reciprocating screw 42 and the end of the motor shaft 44 are magnetically attracted to each other via magnetic cups 43. The opposing surfaces of the two magnetic cups 43 are each provided with a plurality of magnets for magnetic attraction.

[0047] A bracket 2 3 is extended on the surface of the crossbeam 14 toward the angle disk 151, and a sleeve 31 with an open end is fixed on the surface of the bracket 2 3 opposite to the angle disk 151. The opening faces the angle disk 151, making it convenient for the camera 32 to take pictures of it. A bracket 4 333 is extended on the surface of the sleeve 31 toward the reciprocating screw 42, and the reciprocating screw 42 can be supported and suspended by the bracket 4 333, and the camera 32 for taking pictures is fixed in the sleeve 31.

[0048] A second slide groove 37 is provided on the outer surface of the sleeve 31 upward and downward, and a baffle 1 33 and a baffle 2 331 are respectively provided at the opening of the sleeve 31. A slider 38 is fixed near the surface of the baffle 1 33 and the baffle 2 331, and one end of the slider 38 extends to the second slide groove 37, so that the baffle 1 33 and the baffle 2 331 can slide along the second slide groove 37.

[0049] A tooth 332 is fixed at the bottom of the baffle 1 33, and a gear 341 is meshed below the tooth 332. At the same time, a gear frame 34 and a rack frame 39 are extended downward from the bottom surface of the sleeve 31. The shaft extending from the center of the gear 341 passes through the gear frame 34, so that the gear frame 34 can support the gear 341. At the same time, a rack 35 is meshed below the gear 341, and the end of the rack frame 39 extends to the slide groove opened on the surface of the rack 35. One 351, a sleeve 353 is extended toward the reciprocating screw 42 at one end of the rack 35 close to the reciprocating screw 42, and the center of the sleeve 353 is penetrated by the reciprocating screw 42, and an insert is provided on the inner ring wall of the sleeve 353, one end of the insert extends into the path on the surface of the reciprocating screw 42, and the other end is movably connected to the inner ring wall of the sleeve 353, and a connecting rod 352 is connected to the bottom surface of the baffle 2 331 on the upper side of the rack 35. Therefore, when the double-headed motor 4 is controlled by the processor to operate, the double-headed motor 4 generates vibrations when it operates, and the reciprocating screw 42 at one end of the double-headed motor 4 rotates together. After the reciprocating screw 42 rotates, the sleeve 353 sleeved on its outer circumference can slide to one side. When the sleeve 353 slides, the rack 35 drives the gear 341 to rotate, and then the gear 341 causes the upper meshed baffle 1 33 to open to one side. At the same time as the rack 35 moves, the connecting rod 352 drives the baffle 2 331, thereby causing the baffle 2 331 and the baffle 1 33 to move in opposite directions. When the eccentric block 41 vibrates, the baffle 2 331 and the baffle 1 33 move open to facilitate the camera 32 to shoot the corresponding angle. The adjusted angle can then be verified.

[0050] like Figure 10-11 As shown, a bracket 5 36 is fixed to the outer surface of the sleeve 31 near the baffle 2 331. The free end of the bracket 5 36 faces the baffle 2 331. A conductive block 1 361 is fixed to the end of the bracket 5 36. A conductive block 2 334 is fixed to the surface of the baffle 2 331 opposite the conductive block 1 361. Both the conductive block 2 334 and the conductive block 1 361 are electrically connected to the shutter on the camera 32 via wires. When the conductive blocks 2 334 and 1 361 make contact and power, the camera 32 takes a picture. Therefore, when the baffle 2 331 at the opening of the sleeve 31 is pushed to the side by the rack 35, the conductive block 2 334 on the baffle 2 331 moves toward the conductive block 1 361 and eventually makes contact. As the conductive blocks 2 334 and 1 361 make contact and power, the camera 32 takes a picture. The image is then transmitted to the display screen 161, making it convenient for personnel to verify the angle.

[0051] A bedside control method:

[0052] S1: When the angle of the headboard 12 is adjusted, the display screen 161 is controlled and adjusted, and then the processor therein operates the electric push rod 2, and then the electric push rod 2 pushes the headboard 12 to flip through the push rod 21;

[0053] S2: During the turning of the headstock 12, the corresponding mechanical angle can be verified by checking the angle plate 151 and the pointer 143 as the push rod 15 rotates;

[0054] S3: When the headboard 12 reaches the corresponding angle, the processor controls the double-headed motor 4, causing the eccentric block 41 at one end thereof to vibrate, thereby enabling the operator to obtain feedback:

[0055] S4: While the double-headed motor 4 is vibrating and feeding back, the baffle 1 33 and the baffle 2 331 are opened through the reciprocating screw 42 , and then the camera 32 shoots and verifies the angle disk 151 and transmits the image to the display screen 161 .

[0056] The working principle of a medical bed capable of measuring and adjusting the headboard angle is as follows: when the headboard angle of the medical bed needs to be adjusted, the adjustment is controlled on the display screen 161, and then the electric push rod 2 is operated. As the electric push rod 2 operates, the output end of the electric push rod 2 can be extended or shortened. After the length of the electric push rod 2 changes, the push rod 21 hinged to one end thereof can be flipped using the connection on the crossbeam 14 as an axis, so that the top of the push rod 21 pushes the headboard 12, and then the second push rod 122 can move along the length direction of the slide rail 144, so that the headboard 12 completes the corresponding angle adjustment;

[0057] When the headboard 12 is tilted and adjusted by the electric push rod 2, one end of the push rod 15 can rotate around the rotating shaft 142 as the center of the circle. As the rotating shaft 142 rotates, the angle disk 151 fixedly connected to its surface can rotate together. Then, the scale on the surface of the angle disk 151 can be pointed by the pointer 143, and the tilting angle of the headboard can be further verified by the angle disk 151.

[0058] When the double-headed motor 4 is controlled by the processor to operate, the double-headed motor 4 generates vibrations, which are transmitted through the bed frame 1 and can be sensed. At the same time, the reciprocating screw 42 at one end of the double-headed motor 4 rotates together. After the reciprocating screw 42 rotates, the sleeve 353 sleeved on its outer circumference can slide to one side. When the sleeve 353 slides, the rack 35 pushes the gear 341 to rotate, and then the gear 341 causes the upper meshed baffle 1 33 to open to one side. At the same time as the rack 35 moves, the connecting rod 352 drives the baffle 2 331, so that the baffle 2 331 and the baffle 1 33 can move in opposite directions, so that when the eccentric block 41 vibrates, the baffle 2 331 and the baffle 1 33 move open to facilitate the camera 32 to shoot the corresponding angle. The adjusted angle can then be verified.

[0059] Finally, when the baffle 2 331 at the opening of the sleeve 31 is pushed to one side by the rack 35, the conductive block 2 334 on the baffle 2 331 can move toward the conductive block 1 361 and finally contact it. As the conductive block 2 334 and the conductive block 1 361 contact and become conductive, the camera 32 takes a picture, and the image can be transmitted to the display screen 161, making it convenient for personnel to verify its angle.

[0060] It should be noted that the specific models and specifications of the display screen 161, the electric push rod 2, the camera 32, the conductive block 2 334, the conductive block 1 361 and the double-headed motor 4 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be repeated in detail.

[0061] The power supply and principle of the display screen 161, the electric push rod 2, the camera 32, the conductive block 2 334, the conductive block 1 361 and the double-headed motor 4 are clear to those skilled in the art and will not be described in detail here.

[0062] It will be understood that the present invention is described by way of some embodiments, and it will be appreciated by those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are intended to be protected by the present invention.
