[0043] The backrest pin hole 1011 is arranged on the bed frame 101, and the insertion tube insertion hole 1013 is arranged on one side of the bed frame 101. A support structure 102 is installed at the lower part of the bed frame 101 for supporting the entire bed frame 101. The support structure 102 includes legs 1021 and a crossbeam 1022.

[0044] A bed board 103 is placed on the bed frame 101. In order to prevent the movement of the bed board 103 during driving on the road from causing safety hazards to the patient, a groove is provided on the bed frame 101, and the bed board 103 is embedded in the groove and cannot be easily moved. A cushion is provided on the bed board 103, which, on the one hand, improves the comfort of the patient when sitting or lying down, and on the other hand, can also play a buffering role during transportation. Safety belts are provided on the inner and outer sides of the bed frame 101, respectively, which can restrain the patient to the bed when the patient lies on the bed to ensure the patient's safety.

[0045] Protective devices are installed at both ends of the bed frame 101, and the protective devices include guard plates 104 and guardrails 105. When the bed is used as a seat, the guard plates 104 and guardrails 105 are in a vertical state to protect the patient from sliding out of the seat. When the bed is used as a bed, the guard plates 104 and guardrails 105 need to be folded to avoid touching the patient's legs, and the patient's legs and feet can be straightened to improve the patient's comfort.

[0046] The guardrail 105 is an arched circular tube. In order to enable the guardrail 105 and the guard plate 104 to be unfolded and folded at the same time, connecting plates 1051 are provided on both sides of the guard plate 104. The connecting plates 1051 are used to connect with the guardrail 105.

[0047] Furthermore, a protective device lifting structure is also provided. Figure 3 As shown, the protective device lifting structure includes a fixed plate, a first rotating shaft 1052 and a second rotating shaft 1053. The fixed plate 1012 is installed on both sides below the guard plate 104, and two grooves are sequentially arranged on the upper and lower sides of the fixed plate 1012, namely the first groove and the second groove. Two rotating shafts are arranged at corresponding positions at the lower part of the guardrail 105, namely the first rotating shaft 1052 and the second rotating shaft 1053. The first rotating shaft 1052 is arranged in the first groove, and the first rotating shaft 1052 can rotate in the first groove; the second rotating shaft 1053 is arranged in the second groove, and the second rotating shaft 1053 can rotate in the second groove.

[0048] When the guard plate 104 and the guardrail 105 need to be lowered, the guard plate 104 and the guardrail 105 are rotated outward to be parallel to the support legs 1021; when the guard plate 104 and the guardrail 105 need to be raised, the guard plate 104 and the guardrail 105 are rotated inward to be perpendicular to the bed frame 101 and maintained in a vertical state.

[0049] The guard plate 104 and the guardrail 105 need to be locked when they are in a vertical state to prevent the guard plate 104 and the guardrail 105 from rotating and falling. A limiting structure is provided at the second rotating shaft 1053. A limiting piece 1054 is provided between the end of the second rotating shaft 1053 and the guardrail 105, and threaded through holes are provided at the corresponding positions of the lower part of the limiting piece 1054 and the fixed plate 1012. When it is necessary to lock the guard plate 104 and the guardrail 105 in a vertical state, a limiting bolt is inserted into the threaded through hole of the limiting piece 1054 and the fixed plate 1012, so that the first rotating shaft 1052 and the second rotating shaft 1053 cannot rotate, and the guard plate 104 and the guardrail 105 are locked in a vertical state. When it is necessary to drop the guard plate 104 and the guardrail 105, the bolt is removed to release the lock, and the first rotating shaft 1052 and the second rotating shaft 1053 can be rotated outward and folded.

[0050] Compared with the prior art, in order to ensure that the guardrail 105 and the guard plate 104 can be raised and lowered synchronously, the present embodiment provides a connecting plate 1051 to fix the guardrail 105 and the guard plate 104 together. A rotating shaft and a groove are provided, and the rotating shaft rotates in the groove to drive the rotation of the guardrail 105 and the guard plate 104 to achieve lifting and lowering. The structure of the present embodiment is simple and easy to operate, and the switching efficiency of the raising and lowering of the protective device is high. A limiting plate 1054 is provided, and the limiting plate 1054 is installed on the rotating shaft, and a limiting bolt is provided between the limiting plate 1054 and the guardrail 105 to lock the raised state, thereby improving the reliability of the guardrail 105 when it is raised and making the bed safer to use.

[0051] In order to make full use of the space, there is a large space under the seat to place equipment and instruments during the transportation of the cabin. At the same time, in order to meet the needs of different patients and increase the comfort of patients, bed frame lifting mechanisms 107 are set at the four corners of the bed frame 101, which can lift or lower the bed as needed. Figure 4 As shown, the bed frame lifting mechanism 107 includes a lifting motor 1071, a bearing assembly 1072, a nut 1073 and a lead screw 1074. Driven by the lifting motor 1071, the nut 1073 is lifted and lowered along the lead screw 1074, driving the lifting and lowering of the bed frame 101. In order to make the four corners of the bed frame 101 rise and fall synchronously and smoothly, the four bed frame lifting mechanism 107 motors 1081 are aggregated to the central control module 106, and the central control module 106 uniformly adjusts the speed.

[0052] Considering that during the transfer, the patient needs to lie down to rest or be examined. Figure 5 and Figure 6 As shown, the bed board 103 is configured to be able to be lifted. Specifically, the bed board 103 includes a fixed bed board 1031 and a movable bed board 1032. The fixed bed board 1031 and the movable bed board 1032 are rotatably connected, and a bed board hinge shaft is provided between the fixed bed board 1031 and the movable bed board 1032, and the movable bed board 1032 can be rotated and lifted around the bed board hinge shaft.

[0053] Furthermore, a bed board lifting mechanism 108 is provided below the fixed bed board 1031 and the movable bed board 1032. The bed board lifting mechanism 108 includes a motor 1081 and a connecting rod 1082. One end of the motor 1081 is mounted on a motor fixing block 1083 fixed to the bottom of the bed board 103, and a push rod at the other end is connected to the connecting rod 1082 through a rotating shaft. The connecting rod 1082 is an L-shaped rod. One end of the connecting rod 1082 is connected to the push rod of the motor 1081, and the other end is hinged to the movable bed board 1032. A connecting rod rotating shaft 10821 is provided at the inflection point of the connecting rod 1082, and the connecting rod rotating shaft 10821 is fixed to the bottom frame of the fixed bed board 1031. The motor 1081, the connecting rod 1082 and the movable bed board 1032 are combined to form a connecting rod mechanism. The motor fixing block 1083 is provided with an elliptical groove, and the motor 1081 is provided with a limit pin, which can move in the elliptical groove so that the motor 1081 can adjust the angle more conveniently through movement, and also limits the movement of the motor 1081. Figure 6 As shown in (a), when the limit pin moves to the end of the elliptical groove away from the movable bed board 1032, the movable bed board 1032 and the fixed bed board 1031 are in the same plane, and the bed can be used as a seat; Figure 6 As shown in (b), when the limit pin moves toward one end of the elliptical slot close to the movable bed board 1032, the movable bed board 1032 rises, and the rising angle is maximum when reaching the end of the slot, so that the patient can rest more comfortably or the doctor can examine more conveniently.

[0054] When it is necessary to lift the movable bed board 1032, the motor 1081 extends the push rod, and the push rod drives the end of the connected connecting rod 1082 to rotate toward the side away from the bed board 103, and the end of the connecting rod 1082 hinged to the movable bed board 1032 rotates toward the bed board 103, pushing the movable bed board 1032 to be lifted; when it is necessary to lower the movable bed board 1032, the motor 1081 retracts the push rod, and the electric push rod pulls the end of the connected connecting rod 1082 to rotate toward the bed board 103, and the end of the connecting rod 1082 hinged to the movable bed board 1032 rotates toward the side away from the bed board 103, pushing the movable bed board 1032 to be lowered.

[0055] Compared with the prior art, in the limited space of the cabin, this embodiment uses the motor 1081 and the connecting rod 1082 structure to lift the bed board 103, and the structure is stable and reliable. By setting the bed board 103 in the seat as a structure that can be lifted, the seat is transformed into a reclining bed without placing another bed. On the one hand, it can improve the comfort of the patient, and on the other hand, it can achieve a variety of posture changes in a limited space, which can meet the different needs of patients.

[0056] The backrest unit 2 is used for the patient to lean on when sitting, and is arranged on one side of the bed unit 1.

The backrest inserting tube 202 is arranged at the lower part of the backrest. There is a backrest inserting tube 202 on each side of the backrest, which is used to be inserted into the inserting tube insertion hole 1013 in the bed frame 101.

[0057] Furthermore, in order to make the hospital bed more firmly fixed in the cabin, when the bed frame 101 is raised or lowered, the backrest unit 2 can also be raised or lowered together with the bed frame 101. A slide rail is provided on the side wall of the cabin, and a slider is provided on the back of the backrest unit 2. The slide rail is in a vertical direction, and the backrest unit 2 can slide up and down along the slide rail through the slider.

[0058] In order to allow the patient to rest his hands, an armrest 203 is provided between the backrests. Figure 8 As shown, the armrest 203 is mounted on an armrest mounting plate 2031 of the backrest frame 201, and the armrest 203 can be switched between an unfolded state and a folded state.

[0059] The armrest 203 is a long plate with a U-shaped structure, and has a groove at one end near the armrest mounting plate 2031. The armrest mounting plate 2031 is a U-shaped plate, and the armrest 203 is hinged on both sides of the armrest mounting plate 2031, and can rotate around the hinge axis toward one side of the top of the backrest frame 201. When the armrest 203 is unfolded, since the groove at one end of the armrest 203 can clamp the outer side of the armrest mounting plate 2031, the armrest 203 rotates downward around the hinge axis until the length direction of the armrest 203 is perpendicular to the direction of the backrest frame 201 and stops. At this time, the plane of the armrest 203 faces upward, and the two ends of the U shape face the seat. When the armrest 203 is stored, the armrest 203 is rotated upward until it fits with the side of the backrest frame 201. A locking bolt 2032 is provided at the position of the top of the backrest frame 201 corresponding to the armrest 203. When the armrest 203 is in contact with the side of the backrest frame 201 , the locking bolt 2032 is rotated downward until the rod of the locking bolt 2032 blocks the armrest 203 and stops rotating downward, and the armrest 203 is fixed.

[0060] In this embodiment, an armrest 203 and an armrest mounting plate 2031 are provided, and a locking bolt 2032 is used to fix the armrest 203 after it is folded, so that the armrest 203 no longer rotates downward, has a simple structure, is easy to adjust, and reduces space occupation.

[0061] The backrest pad 205 can be tilted according to the patient's needs. A PU hand strap 206 is provided at the lower part of the backrest pad 205. The backrest can be pulled up and adjusted to a desired tilt angle through the PU hand strap 206. After adjustment, the backrest adjustment rod 204 is self-locking.

[0062] The backrest adjustment rod 204 includes a first rod 2041 and a second rod 2042. The end of the first rod 2041 is connected to the side of the backrest cushion 205 through a rotating shaft; the second rod 2042 is connected to the backrest frame 201 through a rotating shaft. The second rod 2042 is hollow inside, and the first rod 2041 can slide inside the second rod 2042. A fixing pin 2043 is fixed on the first rod 2041, and a sawtooth groove is provided on both sides of the second rod 2042. After the PU hand strap 206 pulls up the backrest cushion 205, the first rod 2041 slides inside the second rod 2042, and the fixing pin 2043 can be stuck in the sawtooth groove to complete the locking of the backrest cushion 205. When the angle of the backrest cushion 205 still needs to be adjusted, the backrest cushion 205 is pulled up again, so that the fixing pin 2043 is disengaged from the sawtooth groove, and the first rod 2041 slides inside the second rod 2042 again, and the locking is completed again, and the angle adjustment of the backrest cushion 205 can be completed.

[0063] A quick-insert safety belt is provided on the backrest unit 2 to protect the safety of the patient during transportation.

[0065] Furthermore, in order to ensure the safety of the patient during transfer and prevent the bed from sliding in the transfer cabin, a fixing unit 4 is also provided. The fixing unit 4 is used to lock the bed to the floor of the cabin. The fixing unit 4 is a spring pin structure, which is arranged on the crossbeam 1022 of the bed frame 101, and includes a pin body and a spring. The bottom end of the pin body is a T-shaped structure. A fixing seat is provided on the floor of the cabin, and a straight groove is provided on the upper surface of the fixing seat, and the interior is hollow. During installation, the spring is installed between the head of the pin body and the crossbeam 1022. In the free state, the fixing unit 4 is in a vertical state; when the device needs to be fixed to the floor of the cabin, the T-shaped end at the bottom of the pin body is pressed into the straight groove of the fixing seat, and then rotated so that the part of the T-shaped end inserted into the fixing seat is stuck by the upper surface of the fixing seat to complete the fixation. When moving again, just rotate the T-shaped end, align the T-shaped end with the straight groove to get out of the fixing seat, and the bed can be moved.

[0066] Compared with the prior art, this embodiment uses a spring pin to fix the bed. The cabin floor is installed with a fixing seat 403, and the spring pin is installed at the bottom of the bed. The T-shaped end of the bottom of the spring pin can be inserted into the slot of the fixing seat 403 and fixed after rotation. This structure is quick and convenient to disassemble, simple and firm in structure, high in safety performance, and small in size after disassembly, which is easy to store.

[0067] In order to ensure that the patient's treatment is not delayed during transportation, infusion holes are respectively provided at the four corners of the seat for inserting the infusion unit 5.
