Description

Technical Field

[0001] This invention relates to the field of emergency rescue equipment, and more particularly to an anti-vibration bed. Background Technology

[0002] Existing research indicates that an earthquake-resistant bed device can effectively cope with earthquake disasters and protect the lives of people in the earthquake zone. The core elements of this device are threefold: first, accurate and timely detection of earthquake signals; second, efficient and safe execution of actions to protect the human body; and third, a safe space with sufficient strength and rigidity, as well as sufficient short-term rescue supplies.

[0003] The transmission structure and movement that protect the human body are very important for the device and are important factors affecting its performance. Most existing transmission structures and methods involve flipping the bed board to allow the human body to roll into the safety space, or installing a protective structure above the bed board so that it falls from a height to a certain distance from the human body surface during an earthquake. However, these two methods are still insufficient in terms of protection efficiency and safety. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a shockproof bed with high protection efficiency and safety.

[0005] This invention provides a shock-absorbing bed, comprising: a bed box, a stabilizing frame, a split transmission mechanism, and a cushioning pad;

[0006] The upper part of the bed box is provided with a bed board, which includes a left bed board, a right bed board, and a middle bed board.

[0007] The lower part of the intermediate bed board is connected to two sets of symmetrical stabilizing frames;

[0008] The bed frame is lined with a cushioning pad.

[0009] A set of split transmission mechanisms is arranged at the head and tail of the bed box.

[0010] The split transmission mechanism includes: a DC motor, a reducer, a left support base, a right support base, a left-hand screw nut, a right-hand screw nut, and a screw rod;

[0011] The DC motor is connected to a reducer, and the reducer is connected to a lead screw.

[0012] The lead screw is supported and fixed at both ends by a left support seat and a right support seat;

[0013] Left-hand and right-hand screw nuts mate with the screw rod.

[0014] The left-handed nut is connected to the split left bed plate, and the right-handed nut is connected to the split right bed plate;

[0015] Both ends of the split left bed board are equipped with axles and support brackets, and drive rollers are installed on the axles;

[0016] The lower surface of the supporting angle member is in contact with the driven wheel on the bed box;

[0017] The structure of the split right bed board is the same as that of the split left bed board.

[0018] In one specific embodiment of the present invention, the bed box is a frame-type combined structure, including a base frame, a foot frame, a right side frame, a head frame, and a left side frame;

[0019] The various parts are positioned together by bosses and then fastened together with bolts.

[0020] The headboard and footboard are equipped with driven wheels.

[0021] In one specific embodiment of the present invention, the intermediate bed plate includes: a surface steel plate, and a square tube is provided at the bottom of the steel plate for reinforcement;

[0022] Conical base plates are provided on both the left and right sides of the surface steel plate.

[0023] Ear plates are provided on the bottom surface of the front and rear ends of the surface steel plate.

[0024] In one specific embodiment of the present invention, a toothed boss is provided on the connecting side of the split left bed board and the middle bed board.

[0025] The toothed boss has a conical surface machined on it, which fits against the conical surface on one side of the intermediate bed plate;

[0026] A toothed boss is provided on the connecting side of the split right bed board and the middle bed board.

[0027] The toothed boss has a conical surface machined on it, which fits against the conical surface on the other side of the intermediate bed plate;

[0028] In normal use, the left and right split-opening bed boards, together with the middle bed board, form the entire bed surface.

[0029] In a specific embodiment of the present invention, the split-opening transmission mechanism is controlled by an electrical system to operate synchronously. The split-opening transmission mechanism is connected to the split-opening bed board and is used to control the lateral translation of the split-opening bed board to realize the split-opening bed board opening to the outside and closing to the inside.

[0030] The electronic control system's detection module operates 24 / 7, detecting the instantaneous acceleration, vibration, and changes in vibration of objects during an earthquake in real time. In addition, it integrates a wireless communication module to receive and analyze earthquake information released by the authorities. The conclusions from both are combined to ensure the safety and accuracy of the detection signals.

[0031] The microcontroller of the electronic control system processes the signals collected in real time from the detection module, controls the actuator motor to move, and triggers optical, acoustic and electrical distress signals as well as other distress signals.

[0032] In one specific embodiment of the present invention, a headboard is also included, which is disposed at the front end of the bed frame.

[0033] The electronic control system is located inside the headboard.

[0034] In one specific embodiment of the present invention, the electronic control system is normally powered by a household 220V power supply, and automatically switches to a storage battery to power the device in an emergency, ensuring 3 days of life-saving power supply.

[0035] In one specific embodiment of the present invention, the inner sidewalls of the bed box are wrapped with anti-collision foam.

[0036] In one specific embodiment of the present invention, all components of the bed box are welded together using high-strength profiles and plates.

[0037] In one specific embodiment of the present invention, decorative shells are provided on the left and right sides of the bed box, and louvers and an escape door are provided at the rear; the bed box is equipped with a storage cabinet, which contains a battery and life-saving equipment.

[0038] Compared with existing technologies, the earthquake-resistant bed of this invention achieves emergency safety by integrating two linked degrees of freedom: horizontal opening and closing, and vertical lowering. A DC motor controls the rotation of the lead screw via a reducer, with left-hand and right-hand lead screws transmitting power to control the synchronous horizontal mirror movement of the split bed panels. The vertical lowering of the middle bed panel is linked to the horizontal movement of the split bed panels, enabling rapid and efficient entry and safety for the human body. Furthermore, the structural angle between the split bed panels and the middle bed panel ensures a horizontally centered descent, making the process smoother and safer. The entire transmission system is rationally designed, highly efficient, and safe. Attached Figure Description

Detailed Implementation

[0045] To further understand the present invention, embodiments of the present invention are described below in conjunction with examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of the present invention, and not for limiting the present invention.

[0046] An embodiment of the present invention discloses a shock-absorbing bed, such as Figure 1 As shown, it includes: bed box 2, split transmission mechanism 1, stabilizer 6 and cushioning pad 7;

[0047] The upper part of the bed box 2 is provided with a bed board.

[0048] The bed frame 2 is a frame-type modular structure, including a base frame, a foot frame, a right side frame, a head frame, and a left side frame;

[0049] The various parts are positioned together by bosses and then fastened together with bolts.

[0050] The headboard and footboard are equipped with driven wheels.

[0051] like Figure 2 As shown, the bed board includes a left split bed board 3, a right split bed board 5, and a middle bed board 4 located in the middle.

[0052] The connecting side of the split left bed board 3 and the middle bed board 4 is provided with a toothed boss 18.

[0053] The toothed boss 18 has a conical surface machined on it, which fits against the conical surface on one side of the intermediate bed plate 4;

[0054] A toothed boss 18 is provided on the connecting side of the split right bed board 5 and the middle bed board 4.

[0055] The toothed boss 18 has a conical surface machined on it, which fits against the conical surface on the other side of the intermediate bed plate 4;

[0056] The conical surface on the toothed boss 18 fits against the conical surface of the intermediate bed plate 4, ensuring that the intermediate bed plate 4 is centered and stable during the falling process;

[0057] In normal conditions, the left split bed board 3, the right split bed board 5, and the middle bed board 4 together form the entire bed surface.

[0058] The lower part of the intermediate bed board 4 is connected to two sets of symmetrical stabilizing frames 6, preferably with a hinged connection; the purpose of setting two sets of stabilizing frames is to ensure that the bed board falls horizontally and centered as much as possible.

[0059] like Figure 3 As shown, the intermediate bed board 4 includes: a surface steel plate 19, and a square tube 20 is provided at the bottom of the steel plate for reinforcement;

[0060] Conical base plates 22 are provided on the left and right sides of the surface steel plate 19.

[0061] Ear plates 21 are provided on the bottom surface of the front and rear ends of the surface steel plate 19.

[0062] The bed box 2 is lined with a cushioning pad 7;

[0063] Specifically, the cushioning pad 7 is laid on the base frame to reduce the impact on the human body during a fall;

[0064] The inner sidewalls of the bed box 2 are covered with anti-collision foam 8.

[0065] The cushioning pad 7 and the anti-collision sponge 8 ensure that personnel are protected from collision injuries when falling.

[0066] A set of split transmission mechanisms 1 is arranged at the head and tail of the bed box 2.

[0067] like Figure 4 As shown, the split transmission mechanism 1 includes: a DC motor 9, a reducer 10, a left support base 11, a right support base 15, a left-hand screw nut 12, a right-hand screw nut 14, and a screw 13.

[0068] The DC motor 9 is connected to the reducer 10, and the reducer 10 is connected to the lead screw 13.

[0069] The lead screw 13 is supported and fixed at both ends by the left support seat 11 and the right support seat 15;

[0070] Left-handed nut 12 and right-handed nut 14 are fitted with lead screw 13.

[0071] Left-handed nut 12 is connected to the split left bed plate 3, and right-handed nut 14 is connected to the split right bed plate 5;

[0072] Both ends of the split left bed board 3 are equipped with axles 17 and support angles 16, and drive rollers are installed on the axles 17.

[0073] The lower surface of the supporting angle member 16 is in contact with the driven wheel on the bed box 2;

[0074] The structure of the split right bed board 5 is the same as that of the split left bed board 3.

[0075] In the event of an earthquake, after the left split bed board 3 and the right split bed board 5 are pulled apart by a certain distance, the toothed boss 18 and the lower conical bottom plate 22 of the middle bed board 4 are completely separated. At this time, under the gravity of the human body and the middle bed board 4, the human body falls into the bed box 2. After the human body falls into the bed box 2, the lead screw in the split transmission mechanism 1 begins to rotate in the opposite direction, thereby driving the left split bed board 3 and the right split bed board 5 to move in opposite directions until they contact and close, forming a protective barrier.

[0076] The split-opening transmission mechanism 1 is controlled by the electrical system to operate synchronously. The split-opening transmission mechanism is connected to the split-opening bed board and is used to control the lateral translation of the split-opening bed board to realize the split-opening bed board opening to the outside and closing to the inside.

[0077] The electronic control system's detection module operates 24 / 7, detecting the instantaneous acceleration, vibration, and changes in vibration of objects during an earthquake in real time. In addition, it integrates a wireless communication module to receive and analyze earthquake information released by the authorities. The conclusions from both are combined to ensure the safety and accuracy of the detection signals.

[0078] The microcontroller of the electronic control system processes the signals collected in real time from the detection module, controls the actuator motor to move, and triggers optical, acoustic and electrical distress signals as well as other distress signals.

[0079] The electrical control system is normally powered by a household 220V power supply, but in an emergency it automatically switches to a battery to power the device and ensures 3 days of life-saving power.

[0080] It also includes a headboard, which is located at the front end of the bed frame.

[0081] The electronic control system is located inside the headboard.

[0082] All components of the bed frame 2 are welded from high-strength profiles and plates.

[0083] The bed box 2 has decorative shells on its left and right sides, and louvers and an escape door at its rear. The bed box is equipped with a storage cabinet, which contains batteries and life-saving equipment.

[0084] When the anti-vibration bed detects an earthquake source signal, the electronic control system issues a command to control the DC motor to rotate, which drives the lead screw in the transmission mechanism 1 to rotate. The left-hand lead screw and the right-hand lead screw move synchronously in mirror image, and the active roller rolls along with it, thereby driving the split left bed board 3 and the split right bed board 5 to move away from each other.

[0085] The shock-absorbing bed of the present invention has the following functions:

[0086] 1) This device can withstand the impact of a falling floor slab while the interior of the bed remains undamaged;

[0087] 2) This device can detect seismic signals through sensors and can also acquire seismic information data in a timely manner through a wireless communication system;

[0088] 3) The time it takes for the bed to fall into the bed box shall not exceed 1 second, and the time for the double-leaf bed panels to open and close shall not exceed 6 seconds;

[0089] 4) The container contains essential survival supplies and rescue equipment for 3 days per person;

[0090] 5) The execution of protective actions is safe and efficient.

[0091] The above description of the embodiments is only for the purpose of helping to understand the method and core ideas of the present invention. It should be noted that those skilled in the art can make several improvements and modifications to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.

[0092] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
