Description
Technical Field
[0001] This application relates to the technical field of vehicle-mounted medical beds, and in particular to a vehicle-mounted multifunctional medical bed. Background Technology
[0002] The rescue vehicle is equipped with a medical bed. Placing the patient on the medical bed during the transfer process can minimize changes in the patient's condition.
[0003] When transporting patients, they need to be transferred to a medical bed in the rescue vehicle using a stretcher. However, the space inside the rescue vehicle is limited, and there is not enough space to place the stretcher and medical bed horizontally. The only option is to move the medical bed out of the rescue vehicle, place the patient on the medical bed, and then move the medical bed back into the rescue vehicle. The transfer process is time-consuming and laborious, resulting in low efficiency in patient transport. Summary of the Invention
[0004] To improve transport efficiency, this application provides a vehicle-mounted multifunctional medical bed.
[0005] The vehicle-mounted multifunctional medical bed provided in this application adopts the following technical solution:
[0006] A vehicle-mounted multifunctional medical bed includes:
[0007] The frame has mounting bases fixedly connected to it.
[0008] The bed frame includes an adjustable section and a mounting section. There are two adjustable sections, which are connected to both ends of the mounting section. Connecting plates are fixedly connected to both sides of the mounting section, and the connecting plates are fixed to the mounting base by bolts.
[0009] The transformation assembly includes a limit seat and a limit rod. Multiple limit rods are provided, and the limit rods are rotatably connected to the limit seat. The side walls of the adjustable part and the mounting part are provided with limit holes that are threadedly connected to the limit rods.
[0010] By adopting the above technical solution, the mounting part and the mounting base are detachably connected, allowing the bed to be removed from the frame. After the limiting rod is screwed into the limiting hole, the adjustable part and the mounting plate are aligned in a straight line using the limiting plate. With this structure, the bed can be detached and used as a stretcher when transporting patients. The bed is then fixed back to the frame, simplifying the transfer process and improving efficiency.
[0011] Optionally, the mounting plate is provided with a rotating shaft at each end, and the rotating shaft is a hollow tubular structure;
[0012] The adjustable part is rotatably connected to the mounting part via a rotating shaft. A first drive motor is mounted on the mounting base. The output shaft of the first drive motor is slidably connected to a linkage shaft that is compatible with the rotating shaft. A linkage block is fixedly connected to the outer wall of the linkage shaft. A linkage groove that is compatible with the linkage block is opened on the inner wall of the rotating shaft. A limiting component is provided on one side of the mounting part to keep the linkage shaft inserted into the rotating shaft.
[0013] Using the above technical solution, the linkage shaft is inserted into the rotating shaft through the limiting component. At this time, the linkage block is in the linkage groove. When the first drive motor rotates, the first drive motor drives the rotating shaft to rotate through the linkage shaft and the linkage block, thereby adjusting the angle between the adjustable part and the mounting part.
[0014] Optionally, a limiting groove is formed on the surface of the mounting base;
[0015] The limiting assembly includes a trigger seat and a limiting screw. The limiting screw is rotatably connected in the limiting groove. The limiting screw is a bidirectional screw. There are two trigger seats, both of which are sleeved on the limiting screw. The trigger seats are threadedly connected to the limiting screw. One side of the trigger seat extends out of the limiting groove. The side of the trigger seat extending out of the limiting groove is used to squeeze the linkage shaft into the rotating shaft.
[0016] The mounting base is equipped with a second drive motor for rotating the limit screw.
[0017] Using the above technical solution, when the second drive motor rotates, the limit screw rotates to make the two trigger seats move closer or further apart. When the two trigger seats move closer together, the trigger seats insert the linkage shaft into the rotating shaft; when the two trigger seats move further apart, the trigger seats no longer obstruct the linkage shaft from being pulled out of the rotating shaft, at which point the bed can be removed from the mounting base.
[0018] Optionally, the surface of the mounting base is provided with a drive groove, and a drive roller is rotatably connected to the mounting base in the drive groove. Both ends of the drive roller extend into the limiting groove and are fixedly connected to the limiting screw. A driven bevel gear is fixedly connected to the drive roller.
[0019] The output shaft of the second drive motor is fixedly connected to a driving bevel gear that meshes with the driven bevel gear.
[0020] Using the above technical solution, after the second drive motor starts, it causes the drive roller to rotate through the active bevel gear and the driven bevel gear, thereby causing the two limit screws on the same side to rotate simultaneously. This allows the two linkage shafts on the same side to be inserted into the two rotating shafts respectively, improving the installation efficiency of the bed.
[0021] Optionally, the trigger seat includes a connecting part and a pressing part, the connecting part and the pressing part are fixed together, and the pressing part is semi-circular;
[0022] The rotating shaft is ball-jointed to the side facing the extrusion section.
[0023] Using the above technical solution, after the first drive motor starts, it drives the linkage shaft to rotate. The linkage shaft causes the balls to slide in the groove, replacing the sliding friction between the linkage shaft and the trigger seat with rolling friction, thereby reducing the friction between the linkage shaft and the trigger seat.
[0024] Optionally, the extrusion section has an inclined surface on the side near the linkage shaft, and the extrusion section extrudes the linkage shaft through the inclined surface.
[0025] The above technical solution facilitates the pressing of the trigger seat and the linkage shaft by using the inclined surface.
[0026] Optionally, the adjustable part has a storage groove on the side away from the mounting part, and the adjustable part has a fixed rod fixedly connected to both ends in the storage groove. A movable rod is sleeved on the fixed rod and the two are slidably adapted to each other. A snap-fit assembly is provided between the fixed rod and the movable rod to fix the two together.
[0027] A handle is fixedly connected between the two movable rods within the same storage slot.
[0028] Using the above technical solution, after detaching the bed from the mounting base, pulling the handle causes the moving rod to slide along the fixed rod until the handle is pulled out of the storage slot. At this point, the fixed rod and the moving rod are fixed together by a snap-fit assembly. With this structure, when the bed is used as a stretcher, lifting the bed with the handle facilitates the transfer of patients.
[0029] Optionally, the outer wall of the fixing rod is provided with a sliding groove, and the snap-fit assembly is disposed in the sliding groove;
[0030] The snap-fit assembly includes a snap-fit block and a snap-fit spring. The snap-fit block is slidably adapted to the slide groove. The inner wall of the moving rod has a slot adapted to snap-fit the snap-fit block. The two ends of the snap-fit spring are fixedly connected to the snap-fit block and the fixed rod, respectively.
[0031] Using the above technical solution, when the moving rod slides, after the slide groove aligns with the slot, the locking spring releases its elastic force to insert the locking block into the slot. At this time, there is no longer any relative movement between the moving rod and the fixed rod. When it is necessary to retract the handle into the storage slot, press the locking block to retract it into the locking slot. At this time, there is relative movement between the moving rod and the fixed rod.
[0032] Optionally, the frame includes a load-bearing base and a support frame;
[0033] The surface of the load-bearing seat is provided with a sliding cavity, and a lifting platform is slidably connected in the sliding cavity. The lifting platform is fixedly connected to the mounting seat. A telescopic cylinder is installed in the sliding cavity of the load-bearing seat, and the piston rod end of the telescopic cylinder is fixedly connected to the lifting platform.
[0034] The support frame is a portal frame, and the bottom of the support frame is equipped with self-locking casters.
[0035] Using the above technical solution, after the telescopic cylinder is started, the height of the mounting base is adjusted by the lifting platform, thereby adjusting the height of the bed; during the movement of the rescue vehicle, the self-locking of the casters makes the frame difficult to move, thus improving stability.
[0036] Optionally, the surface of the adjustable part is covered with a first mattress, and a first mounting block is fixedly connected to the side of the first mattress facing the adjustable part. The surface of the adjustable part is provided with a first mounting groove that is adapted to be inserted into the first mounting block, and the first mounting block and the first mounting groove are interference fit.
[0037] The surface of the mounting part is covered with a second mattress, and a second mounting block is fixedly connected to the side of the second mattress facing the mounting part. A second mounting groove is opened on the surface of the mounting part to be inserted and adapted to the second mounting block, and the second mounting block and the second mounting groove are interference fit.
[0038] Using the above technical solution, the first and second mattresses are connected to the bed frame through an interlocking and interference fit, making installation and disassembly very convenient.
[0039] In summary, this application includes at least one of the following beneficial technical effects:
[0040] 1. The mounting section and mounting base are designed with a detachable connection, allowing the bed to be removed from the frame and adjusted into a straight line via a limiting component. This enables the bed to be used as a stretcher during patient transport. A retractable handle is located at the end of the adjustable section for easy handling during bed transport. This simplifies patient transfer and improves transport efficiency.
[0041] 2. The rotation of the second drive motor drives the limit screw to rotate through the drive roller, thereby causing the two trigger seats to move closer to each other, and thus the trigger seats insert the linkage shaft into the rotating shaft; the rotation of the first drive motor causes the rotating shaft to rotate through the linkage shaft and the linkage block, thereby adjusting the angle between the adjustable part and the mounting part.

[0053] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.
[0054] This application discloses a vehicle-mounted multifunctional medical bed.
[0055] refer to Figure 1 A vehicle-mounted multifunctional medical bed includes a frame 1, which includes a frame 11, a load-bearing seat 12, and a support frame 13. The load-bearing seat 12 is fixedly installed inside the frame 11. Covers 10 are fixedly connected to both sides of the frame 11. Guardrails 124 are installed on both sides of the load-bearing seat 12. The support frame 13 is a portal frame, and there are two support frames 13. The two support frames 13 are respectively located at both ends below the load-bearing seat 12. The top of the support frame 13 is fixedly connected to the bottom wall of the load-bearing seat 12. The bottom of the support frame 13 is equipped with self-locking casters 131. A mounting seat 2 is provided above the load-bearing seat 12, and a bed frame 3 is detachably connected to the mounting seat 2.
[0056] When transporting patients, the bed 3 can be detached from the mounting base 2. After the patient is transported to the rescue vehicle, the bed 3 is then fixed back to the mounting base 2. The guardrail 124 reduces the possibility of patients falling off the bed 3, while the self-locking of the casters 131 improves the stability of the medical bed.
[0057] refer to Figure 2 The upper surface of the load-bearing seat 12 is provided with a sliding cavity 121. A telescopic cylinder 123 is installed in the sliding cavity 121. A lifting platform 122 is slidably connected in the sliding cavity 121. The piston rod end of the telescopic cylinder 123 is fixedly connected to the lifting platform 122, and the upper surface of the lifting platform 122 is fixedly connected to the bottom wall of the mounting seat 2.
[0058] When the telescopic cylinder 123 is activated, it drives the lifting platform 122 to move up or down in the sliding cavity 121, thereby driving the mounting base 2 to move up or down, and thus the mounting base 2 drives the bed 3 to move up or down.
[0059] refer to Figure 2 The bed frame 3 includes a mounting part 32, the upper surface of which is covered with a second mattress 9. A second mounting groove 323 is provided on the upper surface of the mounting part 32. A second mounting block 91 is fixed on the surface of the second mattress 9 facing the mounting part 32, which is compatible with the second mounting groove 323. The second mounting block 91 and the second mounting groove 323 are interference fit.
[0060] refer to Figure 3 Two connecting pieces 321 are fixedly connected to both sides of the mounting part 32. The two connecting pieces 321 on the same side are respectively set at both ends of the mounting part 32. The connecting pieces 321 are fixed to the mounting base 2 by bolts.
[0061] refer to Figure 2 and Figure 3The mounting part 32 has a rotating shaft 322 at both ends. The rotating shaft 322 is a hollow tubular structure. The bed body 3 also includes two adjustable parts 31. The two adjustable parts 31 are rotatably connected to the two ends of the mounting part 32 through the two rotating shafts 322 respectively. The upper surface of the adjustable part 31 is covered with a first mattress 8. The upper surface of the adjustable part 31 is provided with a first mounting groove 313. The surface of the first mattress 8 facing the adjustable part 31 is fixed with a first mounting block 81 that is compatible with the first mounting groove 313. The first mounting block 81 and the first mounting groove 313 are interference fit.
[0062] When the first mattress 8 and the second mattress 9 need to be disinfected and replaced, simply pull the first mounting block 81 and the second mounting block 91 out of the first mounting groove 313 and the second mounting groove 323 respectively; when disassembling the bed frame 3, simply unscrew the bolts from the mounting base 2.
[0063] refer to Figure 4 and Figure 5 The inner wall of the rotating shaft 322 is provided with a linkage groove 3221. Each rotating shaft 322 has four linkage grooves 3221. The four linkage grooves 3221 are evenly spaced around the central axis of the rotating shaft 322. Multiple balls 3222 are spherically hinged to the end faces of both ends of the rotating shaft 322.
[0064] refer to Figure 4 and Figure 5 A first drive motor 21 is installed at each of the four corners of the mounting base 2. A linkage shaft 211 is sleeved on the output shaft of the first drive motor 21. A linkage block 2111 that is compatible with the linkage groove 3221 is fixedly connected to the outer wall of the linkage shaft 211. A guide block 2112 is fixedly connected to the inner wall of the linkage shaft 211. There are four guide blocks 2112. The four guide blocks 2112 are evenly spaced around the central axis of the linkage shaft 211. A guide groove 212 that is compatible with the sliding of the guide block 2112 is opened on the outer wall of the output shaft of the first drive motor 21.
[0065] refer to Figure 4 Limiting grooves 22 are provided at the four corners of the mounting base 2. Limiting components 6 are provided in the limiting grooves 22. The limiting components 6 include limiting screws 62. The limiting screws 62 are bidirectional screws, and the two ends of the bidirectional screws are provided with threads with opposite directions of rotation.
[0066] refer to Figure 4 and Figure 5 The limiting component 6 also includes two trigger seats 61. Each trigger seat 61 includes a connecting part 611 and a pressing part 612. The connecting part 611 is square and the pressing part 612 is semi-circular. The bottom of the pressing part 612 is fixedly connected to the upper surface of the connecting part 611.
[0067] refer to Figure 4 and Figure 5The bottom of the connecting part 611 is set in the limiting groove 22 and the two slide and adapt to each other. The bottom of the connecting part 611 is sleeved on the limiting screw 62 and the two are threadedly connected. The two connecting parts 611 in the same limiting groove 22 are respectively set on the two threads of the limiting screw 62 with opposite rotation directions. The pressing part 612 is set outside the limiting groove 22. The pressing part 612 has an inclined surface 6121 on the side facing the rotating shaft 322. The pressing part 612 presses the linkage shaft 211 through the inclined surface 6121.
[0068] refer to Figure 4 , Figure 6 and Figure 7 Both sides of the upper surface of the mounting base 2 are provided with drive grooves 24. The mounting base 2 is rotatably connected to a drive roller 25 in the drive groove 24. The two ends of the drive roller 25 extend into two limit grooves 22 on the same side and are fixedly connected to the limit screw 62. A driven bevel gear 251 is sleeved in the middle position of the drive roller 25. The driven bevel gear 251 is fixedly connected to the drive roller 25. The mounting base 2 is equipped with a second drive motor 23 in the drive groove 24. The output shaft end of the second drive motor 23 is fixedly connected to an active bevel gear 231 that meshes with the driven bevel gear 251.
[0069] The second drive motor 23 starts and drives the active bevel gear 231 to rotate. The active bevel gear 231 drives the driven bevel gear 251 to rotate, which in turn drives the drive roller 25 to rotate. The drive roller 25 drives the limiting screw 62 to rotate, which in turn drives the two connecting parts 611 to move closer together. As a result, the two pressing parts 612 move closer together, and the pressing parts 612 insert the linkage shaft 211 into the rotating shaft 322 through the inclined surface 6121. During the movement of the linkage shaft 211, the linkage shaft 211 drives the guide block 2112 to slide within the guide groove 212.
[0070] When the angle between the adjustable part 31 and the mounting part 32 needs to be changed, the first drive motor 21 is started. The first drive motor 21 drives the linkage shaft 211 to rotate through the guide block. The linkage shaft 211 drives the rotating shaft 322 to rotate through the linkage block 2111, thereby adjusting the angle between the adjustable part 31 and the mounting part 32. During the rotation of the linkage shaft 211, the linkage shaft 211 drives the ball 3222 to roll on the side wall of the extrusion part 612.
[0071] refer to Figure 8 The mounting part 32 has two storage cavities 324 on both sides of its sidewalls. The mounting part 32 has a door panel 325 hinged to the storage cavity 324. The storage cavity 324 contains the conversion component 4.
[0072] refer to Figure 2 and Figure 9The conversion component 4 includes a limiting seat 41 and a limiting rod 42. The limiting seat 41 has a driving cavity 411. Multiple limiting rods 42 are provided. In this embodiment, four limiting rods 42 are provided. The limiting rods 42 are rotatably connected to the limiting seat 41. One end of the limiting rod 42 extends into the driving cavity 411. A driven gear 421 is fixedly connected to the end of the limiting rod 42 that extends into the driving cavity 411. The other end of the limiting rod 42 extends to the outside of the limiting seat 41. The side walls of the mounting part 32 and the adjustable part 31 are provided with limiting holes 5 that are threadedly adapted to the limiting rods 42.
[0073] refer to Figure 9 The conversion assembly 4 also includes a trigger rod 43, which is rotatably connected to the limiting seat 41. One end of the trigger rod 43 extends into the drive cavity 411. The end of the trigger rod 43 extending into the drive cavity 411 is fixedly connected to the drive gear 431 that meshes with the driven gear 421. The other end of the trigger rod 43 extends to the outside of the limiting seat 41. The end of the trigger rod 43 extending out of the limiting seat 41 is fixedly connected to a knob 432. The trigger rod 43 and the limiting rod 42 extend out of the limiting seat 41 on opposite sides.
[0074] refer to Figure 8 and Figure 10 The adjustable part 31 has a storage groove 311 on the end face away from the mounting part 32. Both ends of the adjustable part 31 in the storage groove 311 are fixedly connected to a fixing rod 312. The end of the fixing rod 312 has a sliding groove 3123. A snap-fit component 7 is provided in the sliding groove 3123. The fixing rod 312 is fitted with a moving rod 3121. The moving rod 3121 is a hollow tubular structure. The inner wall of the moving rod 3121 has a slot 31211. A handle 3122 is fixedly connected between the two moving rods 3121 in the same storage groove 311.
[0075] refer to Figure 10 The snap-fit assembly 7 includes a snap-fit block 71 and a snap-fit spring 72. The snap-fit block 71 is slidably adapted to the slide groove 3123 and is also inserted into the slot 31211. The two ends of the snap-fit spring 72 are respectively fixedly connected to the snap-fit block 71 and the fixing rod 312 at the inner wall of the slide groove 3123.
[0076] When a stretcher is needed, the bed frame 3 is removed from the mounting base 2, and the door panel 325 is flipped open to open the storage cavity 324, allowing the conversion component 4 to be removed from the storage cavity 324. After the bed frame 3 is aligned, the limiting seat 41 is moved to align the limiting rod 42 with the limiting hole 5. Then, the knob 432 is turned to rotate the trigger rod 43, which in turn rotates the drive gear 431. The drive gear 431 then rotates the driven gear 421, thereby screwing the limiting rod 42 into the limiting hole 5, thus fixing the adjustable part 31 and the mounting part 32 into a straight line. After the bed frame 3 is aligned, the moving rod 3121 is slid on the fixed rod 312 by pulling the handle 3122 until the slide groove 3123 and the slot 31211 are aligned. At this point, the locking spring 72 releases its elasticity, inserting the locking block 71 into the slot 31211, thus facilitating the movement of the bed frame 3 via the handle 3122.
[0077] The implementation principle of a vehicle-mounted multifunctional medical bed according to this application embodiment is as follows: When a stretcher is needed, the second drive motor 23 is started, which drives the limit screw 62 to rotate via the drive roller 25, thereby moving the two trigger seats 61 away from each other, thus allowing the linkage shaft 211 to be pulled out from the rotating shaft 322; then the bolt is unscrewed from the mounting seat 2, thereby separating the mounting part 32 from the mounting seat 2. After the bed body 3 is disassembled and aligned in a straight line, the limit rod 42 is aligned with the limit hole 5, and the knob 432 is rotated to drive the trigger rod 43 to rotate. The trigger rod 43 drives the limit rod 42 to rotate via the drive gear 431 and the driven gear 421, thereby screwing the limit rod 42 into the limit hole 5. Through the above structure, the efficiency of patient transport is improved.
[0078] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
