Description

Technical Field

[0001] This invention belongs to the field of medical transport beds, specifically a multifunctional electric medical transport bed with obstacle avoidance function. Background Technology

[0002] A multi-functional electric medical transport bed with obstacle avoidance is an advanced medical device used for transporting patients within hospitals. This multi-functional electric medical transport bed with obstacle avoidance has ultrasonic detectors, infrared sensors, or lidar installed at the front end of the bed frame to detect the distance between the frame and obstacles in the surrounding environment in real time. These ranging modules can form a certain range of detection area in various directions. When an obstacle is detected to be less than the set safe distance, the system will immediately issue an alarm.

[0003] Existing multi-functional electric medical transport beds with obstacle avoidance functions generally install the obstacle avoidance device in a fixed position. The angle of the fixed-installation obstacle avoidance device may have a detection blind spot. For example, when there are low obstacles below or diagonally in front of the bed, it cannot be adjusted in time, which may lead to damage to the obstacle avoidance device and failure to sound an alarm in time when an obstacle occurs.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] like Figures 1 to 10As shown in the embodiment of the present invention, a multifunctional electric medical transport bed with obstacle avoidance function includes a base plate 1. Movable mechanisms 2 are fixedly installed at the four corners of the bottom surface of the base plate 1 for stable movement. Each movable mechanism 2 includes support legs 21 fixedly installed at the four corners of the bottom surface of the base plate 1. Mounting seats 22 are fixedly installed at the bottom ends of each support leg 21, and universal wheels 23 are installed inside each mounting seat 22. An obstacle avoidance adjustment mechanism 7 is fixedly installed on the lower surface of the base plate 1 for adjusting the detection orientation to adapt to obstacle recognition needs in different scenarios. A height adjustment mechanism 3 is provided on the upper surface of the base plate 1 for adjusting to a suitable height. A mounting box 4 is fixedly installed at the upper end of the height adjustment mechanism 3 for mounting... The box 4 is equipped with a linkage mechanism 5, and the box 4 is equipped with a reciprocating translation mechanism 6, which is used to drive the linkage mechanism 5 to achieve reciprocating motion. The reciprocating translation mechanism 6 is adapted to the linkage mechanism 5. A storage mechanism 8 is fixedly installed on one side of the box 4 for storing first aid supplies. A position adjustment mechanism 9 is fixedly installed on the upper surface of the storage mechanism 8. A third mounting plate 11 is fixedly installed on the upper surface of the position adjustment mechanism 9. A mounting mechanism 10 is fixedly installed on the upper surface of the third mounting plate 11 for multi-dimensional fixation and position adaptation of the first aid equipment. A second telescopic rod 13 is fixedly installed on one side of the mounting mechanism 10. A water hanger 14 is fixedly installed on the upper end of the second telescopic rod 13.

[0022] Specifically, the moving mechanisms 2 at the four corners of the bottom surface of the base plate 1, with the cooperation of the support legs 21, mounting base 22, and casters 23, provide stable movement for the transport bed, facilitating medical staff to move the transport bed to transfer patients in different areas. The obstacle avoidance adjustment mechanism 7 on the lower surface of the base plate 1, through the linkage of the second servo motor 72, the third servo motor 73 driving the third gear 75, the fourth gear 76, the first bearing 77, the fifth gear 78, the sixth gear 79, the second bearing 710, the first bevel gear 711, and the second bevel gear 712, can drive the obstacle avoidance body 715 to flexibly adjust the detection position. By changing the angle of the obstacle avoidance body 715, it can adapt to... To meet the obstacle recognition needs in different scenarios such as wards and corridors, the system accurately detects the distance between the transport bed and obstacles in the surrounding environment, ensuring safe transport. The height adjustment mechanism 3 on the upper surface of the base plate 1 is activated by the first servo motor 31, which drives the first bidirectional lead screw 32 to rotate. This rotation, via the first sprocket 36, the first chain 38, and the second sprocket 37, causes the second bidirectional lead screw 33 to rotate synchronously. The first slider 34 and the second slider 35 on the first and second bidirectional lead screws 32 and 33 move, coordinating with the first support 39, the first crank 311, the second support 310, and the first telescopic rod 312 to achieve flexible height adjustment of the mounting box 4. To accommodate the needs of medical staff of different heights and the connection of different beds, the linkage mechanism 5, with the help of components such as the first drive shaft 51, the third sprocket 53, the second chain 55, the fourth sprocket 54, and the second drive shaft 52 within the turntable 63, enables the first gear 57 to mesh with the rack 58, driving the first mounting plate 59 to slide along the through groove of the mounting box 4. This, along with the connecting block 510, allows the transport bed 511 to move horizontally. In conjunction with the reciprocating translation mechanism 6, it completes actions such as patient transfer. The storage mechanism 8 on one side of the mounting box 4, the storage box 81, allows for convenient storage and retrieval of emergency supplies such as the first aid kit 82 via hinges 83, a door 84, and a handle 85. The storage box 81 has a... The adjustment mechanism 9, with the cooperation of the mounting cylinder 91, the shock-absorbing damping spring 92, the first gear plate 94, the second gear plate 95, and the second guide post 93, adjusts the position of the third mounting plate 11. The mounting mechanism 10 on the third mounting plate 11, the second mounting bracket 101, the third guide post 103, the pull plate 102, the return spring 104, and the rubber pad 105 work together to fix and adapt the emergency instruments such as the detector 106 in multiple dimensions. To meet different testing needs, the second telescopic rod 13 on one side of the mounting mechanism 10 can be flexibly adjusted in height. The water hanger 14 at the upper end of the second telescopic rod 13 is used to suspend infusion equipment and provide support for infusion therapy.

[0023] like Figures 2 to 4As shown, the obstacle avoidance adjustment mechanism 7 includes a second mounting plate 71 fixedly mounted on the lower surface of the base plate 1. A second servo motor 72 is fixedly mounted on one side of the second mounting plate 71. A fifth gear 78 is fixedly mounted on the output end surface of the second servo motor 72, passing through the second mounting plate 71. A second bearing 710 is sleeved at the output end of the second servo motor 72. A sixth gear 79 is fixedly mounted on the surface of the second bearing 710. A third gear 75 is meshed with one side of the fifth gear 78. A second rotating shaft 74 is fixedly mounted inside the third gear 75, and the second rotating shaft 74 is fixedly mounted on the second mounting plate 71. A first bearing 77 is sleeved at the end of the second rotating shaft 74. A fourth gear 76 is fixedly mounted on the surface, and the fourth gear 76 meshes with the sixth gear 79. A first bevel tooth 711 is fixedly mounted on the end of the first bearing 77. A fixed shaft 713 is fixedly mounted on the end of the second rotating shaft 74. A second bevel tooth 712 is fixedly mounted on the surface of the fixed shaft 713. The first bevel tooth 711 and the second bevel tooth 712 mesh with each other. A first mounting bracket 714 is fixedly mounted on both ends of the fixed shaft 713. A third servo motor 73 is fixedly mounted on one side of the first mounting bracket 714, and the output end of the third servo motor 73 is fixedly connected to the fixed shaft 713. An obstacle avoidance body 715 is provided on the mounting bracket for detecting the distance between the medical transport bed and obstacles in the surrounding environment.

[0024] Specifically, the second mounting plate 71 provides fixed support for the overall structure. When the orientation of the obstacle avoidance body 715 needs to be adjusted, the second servo motor 72 is activated. The output end of the second servo motor 72 drives the fifth gear 78 fixed on the surface to rotate. The fifth gear 78 meshes with the third gear 75, thereby driving the third gear 75 to rotate. Since the third gear 75 has a second rotating shaft 74 fixed inside, and the second rotating shaft 74 is rotatably mounted on the second mounting plate 71, the rotation of the third gear 75 will drive the second rotating shaft 74 to rotate synchronously. When the second rotating shaft 74 rotates, it drives the first mounting frame 714 to rotate through the fixed shaft 713 at the end of the second rotating shaft 74, so that the obstacle avoidance body 715 on the first mounting frame 714 can achieve angle adjustment. During this process, the first bevel tooth 711 and the fourth gear 76 are connected through the first... Bearing 77 is mounted on the second rotating shaft 74, which can maintain smooth rotation during angle adjustment. The fourth gear 76 simultaneously drives the sixth gear 79, which meshes with it, to rotate. Since the sixth gear 79 is mounted on the output end of the second servo motor 72 through the second bearing 710, the transmission stability is further improved. When the orientation needs to be adjusted, the third servo motor 73 is started. The output end of the third servo motor 73 drives the fixed shaft 713 to rotate. The second bevel tooth 712 on the surface of the fixed shaft 713 rotates synchronously. The second bevel tooth 712 meshes with the first bevel tooth 711, driving the first bevel tooth 711 to rotate, thereby realizing the orientation adjustment of the obstacle avoidance body 715. Through such coordinated transmission, the obstacle avoidance body 715 can flexibly adjust its orientation and angle to adapt to scenarios such as wards and corridors, accurately detect the distance to obstacles, and ensure safe transportation.

[0025] like Figures 2 to 4 As shown, the height adjustment mechanism 3 includes a first servo motor 31 fixedly installed on one side of the base plate 1. A slide groove is provided in the base plate 1. A first bidirectional lead screw 32 is fixedly connected to the output end of the first servo motor 31, and the first bidirectional lead screw 32 is rotatably installed in the slide groove. A first sprocket 36 is fixedly installed at the end of the first bidirectional lead screw 32. A first chain 38 is meshed on the first sprocket 36. A second sprocket 37 is meshed at the end of the first chain 38 away from the first sprocket 36. A second bidirectional lead screw 33 is fixedly installed inside the second sprocket 37, and the second bidirectional lead screw 33 is rotatably installed in the slide groove. The surface of the first bidirectional lead screw 32 is threaded with two sets of second sliders 35, and the surface of the second bidirectional lead screw 33 is threaded with two sets of first sliders 34. The upper surfaces of the two sets of first sliders 34 and the two sets of second sliders 35 are all fixedly mounted with first supports 39. The first supports 39 are all fixedly mounted with first cranks 311 by pins. The first cranks 311 are all fixedly mounted with second supports 310 at one end. The bottom end of the second supports 310 is fixedly connected to the mounting box 4. The upper surface of the base plate 1 is fixedly mounted with a first telescopic rod 312, and one end of the first telescopic rod 312 is fixedly connected to the mounting box 4.

[0026] Specifically, the base plate 1 serves as the foundation support, and the internal groove of the base plate 1 provides installation space for the transmission components. After the first servo motor 31 is started, the output end of the first servo motor 31 drives the first bidirectional lead screw 32 to rotate in the groove. The first sprocket 36 at the end of the first bidirectional lead screw 32 rotates synchronously, driving the second sprocket 37 and the internal second bidirectional lead screw 33 to rotate synchronously through the first chain 38. At this time, the two sets of second sliders 35 on the first bidirectional lead screw 32 and the two sets of first sliders 34 on the second bidirectional lead screw 33 slide towards or in opposite directions along the axial direction of the first bidirectional lead screw 32 and the second bidirectional lead screw 33. The first supports 39 on the two sets of second sliders 35 and the two sets of first sliders 34 drive the first crank 3 through the pin. When crank 311 rotates, the first crank 311 pushes the mounting box 4 up and down through the second support 310. At the same time, the first telescopic rod 312 on the base plate 1 extends and retracts synchronously with the mounting box 4 to help maintain stability. Through the synchronous transmission of the first bidirectional lead screw 32 and the second bidirectional lead screw 33 with the first chain 38, the second sprocket 37 and the first sprocket 36, the movement of the two sets of second sliders 35 and the two sets of first sliders 34 is ensured to be consistent, improving the stability of height adjustment. The linkage structure of the first crank 311, together with the first telescopic rod 312, can accurately control the height of the mounting box 4, adapting to different bed docking or operation needs. The overall transmission structure is compact, and the first servo motor 31 drives it efficiently, which can quickly complete the height adjustment and reduce the waiting time for patient transfer.

[0027] like Figures 6 to 7As shown, the reciprocating translation mechanism 6 includes a first drive motor 68 fixedly installed on one side of the mounting box 4. The output end of the first drive motor 68 is fixedly connected to a transmission rod 69. The transmission rod 69 is movably connected to a first rotating shaft 67 via a pin. Two sets of second fixing plates 64 are fixedly installed on the inner wall of the mounting box 4. First guide posts 65 are fixedly installed at equal intervals on the two sets of second fixing plates 64. A third slider 66 is slidably sleeved on the surface of the first guide post 65. The third slider 66 is movably connected to the first rotating shaft 67 via a pin. A second gear 61 is fixedly installed at the end of the first rotating shaft 67. An arc-shaped internal gear ring 62 is meshed on the surface of the second gear 61. A turntable 63 is fixedly installed on one side of the arc-shaped internal gear ring 62. One side of the turntable 63 is fixedly connected to the linkage mechanism 5. The linkage mechanism 5 includes a first drive shaft 51 fixedly installed inside the turntable 63. A third sprocket 53 is fixedly installed at the middle end of the first drive shaft 51. A second chain 55 is meshed on the third sprocket 53. A fourth sprocket 54 is meshed at the end of the second chain 55 away from the third sprocket 53. A second drive shaft 52 is fixedly installed inside the fourth sprocket 54. A first fixing plate 56 is equidistantly arranged on the surfaces of the second drive shaft 52 and the first drive shaft 51. The first fixing plate 56 is fixedly installed on the inner wall of the mounting box 4. A first gear 57 is fixedly installed at the ends of both the second drive shaft 52 and the first drive shaft 51. A rack 58 is meshed on one side of the first gear 57. A first mounting plate 59 is fixedly installed at the top of the rack 58. A through groove is opened on one side of the mounting box 4. The first mounting plate 59 is slidably installed in the through groove. A connecting block 510 is fixedly installed at the top of the first mounting plate 59. A transport bed 511 is fixedly installed at the top of the connecting block 510.

[0028] Specifically, when the transport bed 511 needs to be driven to reciprocate, when the first drive motor 68 is started, the output end of the first drive motor 68 drives the transmission rod 69 to rotate. The transmission rod 69 pulls the first rotating shaft 67 to move through the pin. At this time, the first rotating shaft 67 is constrained by the internal structure of the mounting box 4. The third slider 66 is sleeved on the first guide post 65 between the two sets of second fixed plates 64, so that the third slider 66 can only slide back and forth along the direction of the first guide post 65. At the same time, the first rotating shaft 67 rotates synchronously. As the first rotating shaft 67 slides, the second gear 61 fixed at the end of the first rotating shaft 67 moves synchronously. The second gear 61 at the end of the first rotating shaft 67 continuously meshes with the arc-shaped internal gear ring 62. Due to the meshing relationship between the two, when the first rotating shaft 67 rotates, the second gear 61 drives the arc-shaped internal gear ring 62 to rotate periodically, thereby causing the turntable 63 fixed with the arc-shaped internal gear ring 62 to rotate eccentrically synchronously. When the turntable 63 rotates, it drives the internally fixed first drive shaft 51 to rotate. The third sprocket 53 at the middle end of the first drive shaft 51 rotates accordingly. Through the second chain 55, it links the fourth sprocket 54, causing the second drive shaft 52 to rotate synchronously with the first drive shaft 51. The first fixing plates 56, which are equidistantly arranged on the surfaces of the second drive shaft 52 and the first drive shaft 51, are fixed to the inner wall of the mounting box 4, providing stable support and ensuring smooth transmission. Finally, the first gear 57 at the ends of the second drive shaft 52 and the first drive shaft 51 rotate synchronously and mesh with the rack 58, converting the rotational motion into the linear reciprocating motion of the rack 58. The first mounting plate 59 at the top of the rack 58 slides along the side groove of the mounting box 4 and drives the transport bed 511 to complete the reciprocating translation via the connecting block 510. This completes the process from the first drive motor 68 driving the transport bed 511 to move, meeting the needs of patient transfer in medical scenarios.

[0029] like Figure 8 As shown, the storage mechanism 8 includes a storage box 81 fixedly installed on one side of the mounting box 4. A hinge 83 is provided on one side of the storage box 81. A door 84 is welded to the storage box 81 through the hinge 83. A handle 85 is fixedly installed on the surface of the door 84. A first aid kit 82 is provided inside the storage box 81 for emergency first aid. The top of the storage box 81 is fixedly connected to the position adjustment mechanism 9.

[0030] Specifically, an independent storage space is constructed by fixing a storage box 81 to one side of the installation box 4. Utilizing the connection characteristics of the hinge 83, the box door 84 can rotate flexibly around the hinge 83 to open and close the storage box 81. The handle 85 provides a force point for opening and closing the box door 84, making it convenient for medical personnel to operate. The storage box 81 is used to store a first aid kit 82. In case of emergency, the box door 84 can be opened quickly to retrieve the first aid kit for emergency treatment. At the same time, the top of the storage box 81 is fixed to the position adjustment mechanism 9. With the help of the position adjustment mechanism 9, it can adapt to the retrieval needs of medical personnel in different scenarios, making the storage and retrieval of the first aid kit 82 more convenient and efficient, and providing basic and practical material storage for medical emergency operations.

[0031] like Figures 8 to 10 As shown, the position adjustment mechanism 9 includes a mounting cylinder 91 fixedly installed at the top of the storage box 81. A shock-absorbing damping spring 92 is fixedly installed on the inner wall of the bottom end of the mounting cylinder 91. A first gear 94 is fixedly installed at one end of the shock-absorbing damping spring 92, and the first gear 94 is slidably installed inside the mounting cylinder 91. A second gear 95 is meshed with one end of the first gear 94. The second gear 95 is fixedly installed on the inner wall of the top end of the mounting cylinder 91. A second guide post 93 is fixedly installed inside the first gear 94. The second guide post 93 is slidably installed inside the mounting cylinder 91, and the top end of the second guide post 93 is fixedly connected to the third mounting plate 11. Next, the installation mechanism 10 includes a second mounting bracket 101 fixedly mounted on the upper surface of the third mounting plate 11. Two sets of third guide posts 103 are symmetrically slidably mounted in the second mounting bracket 101 along the horizontal direction. A pull plate 102 is fixedly mounted on one end of each set of third guide posts 103. A rubber pad 105 is fixedly mounted on the end of each set of third guide posts 103 away from the pull plate 102. A return spring 104 is sleeved on the surface of each set of third guide posts 103, and one end of the return spring 104 is fixedly mounted on the pull plate 102. A detector 106 is in contact with one side of the rubber pad 105 for detecting the patient.

[0032] Specifically, in the position adjustment mechanism 9, the mounting cylinder 91 is fixed to the top of the storage box 81, providing support for the whole. When the position of the third mounting plate 11 needs to be adjusted, an external force is applied to the second guide post 93, causing the second guide post 93 to slide inside the mounting cylinder 91. The second guide post 93 drives the first gear plate 94 to move synchronously. When the first gear plate 94 slides, it compresses the shock-absorbing damping spring 92 and simultaneously disengages from the second gear plate 95. After adjusting to the appropriate position, the external force is removed, the shock-absorbing damping spring 92 returns to its original position, and pushes the first gear plate 94 to re-engage with the second gear plate 95, thus fixing the position. The shock-absorbing damping spring 92 can also buffer vibrations. To ensure the stability of the third mounting plate 11 at the top of the second guide post 93, when the mounting mechanism 10 is working, the pull plate 102 is pulled, and the pull plate 102 drives the two sets of third guide posts 103 to slide within the second mounting frame 101. The return spring 104 is compressed. After the detector 106 is placed between the two sets of rubber pads 105, the pull plate 102 is released, the return spring 104 rebounds, and pushes the third guide post 103 to reset. The rubber pads 105 tightly adhere to the detector 106, completing the fixation. The rubber pads 105 can prevent the detector 106 from being pinched and damaged, and at the same time enhance the friction, ensuring the stability of the instrument during the detection process and facilitating the detection of patients.

[0033] Working principle: The moving mechanisms 2 at the four corners of the bottom surface of the base plate 1, with the cooperation of the support legs 21, mounting bases 22, and casters 23, provide stable movement for the transport bed, facilitating medical staff to move the transport bed to different areas for patients. The obstacle avoidance adjustment mechanism 7 on the lower surface of the base plate 1, through the linkage of the second servo motor 72, the third servo motor 73 driving the third gear 75, the fourth gear 76, the first bearing 77, the fifth gear 78, the sixth gear 79, the second bearing 710, the first bevel gear 711, and the second bevel gear 712, can drive the obstacle avoidance body 715 to flexibly adjust the detection position. By changing the angle of the obstacle avoidance body 715, it can be adapted to the ward, To meet obstacle recognition needs in various scenarios such as corridors, the system accurately detects the distance between the transfer bed and surrounding obstacles, ensuring safe transfer. The height adjustment mechanism 3 on the upper surface of the base plate 1 utilizes a first servo motor 31. The first servo motor 31 drives the first bidirectional lead screw 32 to rotate, which, via the first sprocket 36, first chain 38, and second sprocket 37, causes the second bidirectional lead screw 33 to rotate synchronously. The first slider 34 and the second slider 35 on the first and second bidirectional lead screws 32 and 33 move, coordinating with the first support 39, first crank 311, second support 310, and first telescopic rod 312 to achieve flexible height adjustment of the mounting box 4. To accommodate the needs of medical staff of different heights and for connecting different beds, the linkage mechanism 5 utilizes components such as the first drive shaft 51, third sprocket 53, second chain 55, fourth sprocket 54, and second drive shaft 52 within the turntable 63 to engage the first gear 57 with the rack 58, driving the first mounting plate 59 to slide along the through groove of the mounting box 4. This, along with the connecting block 510, enables the translation of the transport bed 511. In conjunction with the reciprocating translation mechanism 6, it facilitates patient transfer and other actions. The storage mechanism 8 on one side of the mounting box 4, the storage box 81, allows for convenient storage and retrieval of emergency supplies such as the first aid kit 82 via hinges 83, a door 84, and a handle 85. The storage box 81 has various positions... The adjustment mechanism 9, through the cooperation of the mounting cylinder 91, the shock-absorbing damping spring 92, the first gear plate 94, the second gear plate 95, and the second guide post 93, adjusts the position of the third mounting plate 11. The mounting mechanism 10 on the third mounting plate 11, the second mounting bracket 101, the third guide post 103, the pull plate 102, the return spring 104, and the rubber pad 105 work together to fix and adapt the emergency instruments such as the detector 106 in multiple dimensions. To meet different testing needs, the second telescopic rod 13 on one side of the mounting mechanism 10 can be flexibly adjusted in height. The water hanger 14 at the upper end of the second telescopic rod 13 is used to suspend infusion equipment and provide support for infusion therapy.
