AI Technical Summary
In the CPR function, the motor is easily damaged due to the motor rollback too quickly and the descent speed is difficult to control, which may cause secondary injury to the patient.
The combination design of CPR motor, damping spring, hinge and through shaft is adopted. Through appropriate hole distance and connection, the damping spring gradually increases the thrust during the downward plate of the bed, offsets part of the downforce, and achieves flexible landing.
Effectively control the drop speed of the bed back plate, avoid motor damage, reduce patient vibration damage, and ensure safe first aid operations.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of emergency beds, and particularly relates to a slow descent structure of an emergency bed board. Background Technique
[0002] An emergency bed is mainly a special bed for emergency rescue and ambulance work, usually composed of a strong metal structure and a comfortable mattress. In the event of a power grid voltage interruption, the backrest of the hospital electric bed can also be lowered to ensure that the patient can lie flat for emergency rescue during a power outage. However, sometimes manual CPR function is required. To achieve the manual CPR function, a motor with CPR function can be selected and installed.
[0003] All beds on the market do not take any protective measures and directly install the CPR motor on the bed. The disadvantage is that the motor retreats too fast and is easy to damage the motor. Especially in the semi-clutch state, under the action of the gravity of the human body on the back and the self-weight of the bed board, breaking through the resistance brought by the semi-clutch, the backrest of the bed can also be lowered, but it will further damage the motor and affect normal use. Moreover, when the backrest of the bed accelerates downward, even if the caregiver tries to hold up the bed board with force at this time, it is very difficult to avoid finally hitting the bed frame assembly, causing the patient to be strongly shaken and even causing secondary injuries. Content of the Utility Model
[0004] The purpose of the utility model is to provide a slow descent structure of an emergency bed board to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] A slow descent structure of an emergency bed board, comprising:
[0007] A bed board assembly;
[0008] A backrest of the bed, the backrest of the bed is arranged outside the bed board assembly;
[0009] A CPR motor, the CPR motor is installed on the outer side wall of the bed board assembly.
[0010] Preferably, one end of the CPR motor is connected with a damping spring, and the bottom end of the backrest of the bed is connected with a hinge.
[0011] Preferably, one end of the CPR motor is connected with a second through shaft, a first through shaft is arranged above the second through shaft, and one end of the damping spring is rotatably connected with a third through shaft.
[0012] Preferably, the backrest of the bed is rotatably connected to the outside of the bed board assembly through a hinge, and the first through shaft is rotatably connected to the outside of the bed board assembly.
[0013] Preferably, the damping spring is rotatably connected to the outside of the third through-shaft, and the CPR motor is fixedly installed on the outer side wall of the bedplate assembly by screws.
[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0015] By providing the CPR motor, the damping spring, the hinge and the first through-shaft, the present utility model enables the design of an appropriate hole pitch, places the CPR machine and a damping spring side by side, installs the rear mounting hole of the damping spring at an appropriate position on the bed frame assembly using the through-shaft, installs the mounting hole of the front piston rod of the damping spring at an appropriate position on the bed backrest. During the process of lowering the bed backrest, the downward pressure on the bed backrest gradually increases, and during the process of the damping spring actively shortening, its thrust also becomes larger and larger. This thrust can offset part of the downward pressure. At this time, the caregiver only needs to gently push the bed backrest upward to control the lowering speed of the bed backrest and achieve the soft landing of the bed backrest.

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0020] Embodiment 1:
[0021] Please refer to Figure 1 - Figure 2 as shown, a slow descent structure for the bedplate of a first aid bed, comprising:
[0022] Bedplate assembly 1;
[0023] Bed backrest 2, the bed backrest 2 is arranged outside the bedplate assembly 1;
[0024] The CPR motor 3 is installed on the outer wall of the bedplate assembly 1. One end of the CPR motor 3 is connected with a damping spring 4. The bottom end of the headboard 2 is connected with a hinge 5. One end of the CPR motor 3 is connected with a second through shaft 7. Above the second through shaft 7, there is a first through shaft 6. One end of the damping spring 4 is rotatably connected with a third through shaft 8. The headboard 2 is rotatably connected to the outside of the bedplate assembly 1 through the hinge 5. The first through shaft 6 is rotatably connected to the outside of the bedplate assembly 1. The damping spring 4 is rotatably connected to the outside of the third through shaft 8. The CPR motor 3 is fixedly installed on the outer wall of the bedplate assembly 1 by screws.
[0025] Specifically, the first through shaft 6 is adapted to the damping spring 4, the second through shaft 7 is adapted to the CPR motor 3, and the third through shaft 8 is designed with concentric shafts for the CPR motor 3 and the damping spring 4. The CPR motor 3 is based on a conventional motor, with a clutch device added inside that only functions for the motor to retract. A lock is designed on the outside of the motor to connect a steel wire rope, and the other end of the steel wire rope is connected to a handle.
[0026] As can be seen from the above, a damping spring 4 is arranged in parallel with the CPR motor 3. The rear mounting hole of the damping spring 4 is installed at an appropriate position on the bedplate assembly 1 with the first through shaft 6, and the mounting hole of the front piston rod of the damping spring 4 is installed at an appropriate position on the headboard 2 with the first through shaft 6. During the process of the headboard 2 descending, the downward pressure becomes greater and greater, and during the process of the damping spring 4 being passively shortened, its thrust also becomes greater and greater. This thrust offsets part of the downward pressure. At this time, the caregiver only needs to slightly lift the headboard 2 upward to control the descending speed of the headboard 2, thus achieving the soft landing of the headboard 2.
