Description

Technical Field

[0001] The present invention relates to the technical field of medicine cabinet drawers, and in particular to a medicine cabinet drawer with high safety. Background Art

[0002] In the medical field, the storage and management of special medicines is a crucial task, directly related to the patient's treatment effect and life safety. These special medicines often have extremely strict requirements on storage environment conditions such as temperature and humidity. Any slight deviation may affect the stability and effectiveness of the medicine, thereby leading to reduced efficacy or even deterioration, thereby causing serious medical consequences.

[0003] However, traditional drug storage methods mostly rely on manual operations and simple physical facilities, lack intelligent management methods, and find it difficult to accurately count and monitor drug inventory in real time. This not only increases the risk of drug expiration, misuse, or loss, but also poses challenges to the effective allocation of medical resources. Traditional drug storage drawers require manual operation. During the opening and closing process, medical staff may forget to completely close the drawers due to busyness or negligence, which not only causes drugs to be exposed to inappropriate environments, but may also cause a series of safety issues.

[0004] Smart medicine cabinets with electric drives that automatically open and close drawers are already available on the market, but these products also have shortcomings. For example, if a user's hand is accidentally pinched while using a drawer, if the electric drive continues to drive the drawer closed, it will cause further harm to the user. Therefore, how to improve the safety of such products is an urgent problem that needs to be solved. Summary of the Invention

[0005] The purpose of the present invention is to overcome the shortcomings and deficiencies of the prior art and to provide a medicine cabinet drawer with high safety.

[0016] The beneficial effects of the present invention are as follows: The present invention forms a dual protection mechanism through the collaborative design of multi-sensor redundant triggering and mechanical linkage instant unlocking, which completely solves the hidden danger of finger pinching. Specifically, when the anti-pinch plate moves, the sensor and mechanical unlocking are triggered synchronously. Among them, the signal sensor triggers the motor to stop working, mainly to prevent the motor from continuing to work to close the drawer and causing primary injury to the user, while the mechanical unlocking allows the drawer body and the push plate to be directly separated, that is, it can be pulled and pulled like a regular drawer, avoiding secondary injury. At the same time, in scenarios such as motor failure or sensor failure, when the anti-pinch plate is squeezed, the mechanical transmission rod can still directly push the flap to unlock, ensuring safety in extreme situations.

[0025] Regarding the drawings of this application, it should be clearly understood that the drawings are for illustration and description purposes only and are not intended to limit the scope of this specification. It should also be understood that the drawings are not necessarily drawn to scale.

[0026] Traditional smart medicine cabinets use electric drives to automatically open and close drawers. In medical scenarios, medical staff often get their hands pinched by closed medicine cabinet drawers due to urgent medication, hurried operations, or distraction. If the electric drive continues to drive the drawer closed, it will cause further harm to the user. Therefore, how to improve the safety of such products is an urgent problem that needs to be solved.

[0027] Based on the above problems, Figures 1 to 11As shown, the present application provides a high-security medicine cabinet drawer, including a drawer tray 1, a drawer body 2, a drive assembly 3, an anti-pinch assembly 4, a snap assembly 5, a linkage assembly 6, an emergency opening assembly and a controller 7, wherein the drive assembly 3 includes a motor 30, a screw rod 31, a push plate 32 and an electromagnetic coupling 33, wherein the push plate 32 is a vertical plate perpendicular to the screw rod 31, and a threaded hole adapted to the screw rod 31 is provided in the middle thereof, and is sleeved on the screw rod 31 through threaded fitting; two guide rods 34 are provided in parallel on both sides of the screw rod 31, and the two ends of the guide rod 34 are respectively fixed to the front end and the rear end of the drawer tray 1, and sliding holes adapted to the guide rod 34 are provided on both sides of the push plate 32, and the rotational freedom of the push plate 32 is limited by the guide rod 34, so that it slides smoothly along the axial direction of the screw rod 31, and the electromagnetic coupling 33 is arranged between the output shaft of the motor 30 and the screw rod 31. It is a normally closed electromagnetic clutch. When the power is on, it is engaged, transferring the torque of the motor 30 to the screw 31. When the power is off, it is separated, disengaging the screw 31 from the motor 30, allowing manual pushing and pulling of the drawer body 2. Optionally, the electromagnetic coupling 33 can be used in conjunction with the motor 30, or it can be controlled separately by setting a button. The drawer main body 2 is slidingly arranged relative to the drawer tray 1. For example, two groups of drawer slide rails 13 are symmetrically arranged on both sides of the drawer tray 1, and two slide bars 14 are symmetrically arranged on both sides of the drawer main body 2. The slide bars 14 slide and cooperate with the drawer slide rails 13. Specifically, the drawer slide rail 13 is a C-shaped groove structure extending along the opening and closing direction of the drawer, and a ball bearing is provided in the groove. The slide bar 14 is a strip-shaped protrusion adapted to the C-shaped groove, which is embedded in the drawer slide rail 13 and realizes low-friction sliding through the ball bearing.

[0028] To prevent the internal cables from getting entangled when the drawer body 2 slides, a cable trough drag chain 15 is fixed to one side of the drawer tray 1. One end of the cable trough drag chain 15 is fixed to the rear end of the drawer tray 1, and the other end is fixed to the rear end outer wall of the drawer body 2. The internal cables of the drawer body 2 are passed through the cable trough drag chain 15 and extend and retract synchronously with the opening and closing of the drawer.

[0029] The anti-pinch assembly 4 is used to prevent the user from being pinched when the drawer body 2 is closed. The anti-pinch assembly 4 includes a fixed seat 40 arranged on the inner side of the door panel of the drawer body 2, an anti-pinch plate 41 slidingly arranged relative to the fixed seat 40 along the opening and closing direction of the drawer body 2, and a spring 42 arranged therebetween. For example, a plurality of springs 42 are arranged between the fixed seat 40 and the anti-pinch plate 41 to ensure that a certain distance is always maintained between the fixed seat 40 and the anti-pinch plate 41 when there is no external force pushing the anti-pinch plate 41. The anti-pinch plate 41 is slidably mounted with multiple positioning rods 45. A user can press the anti-pinch plate 41 to slide along the positioning rods 45. The positioning rods 45 are threaded at their ends and extend through the mounting base 40, where they are threadedly connected to nuts 46. The abutment between the nuts 46 and the mounting base 40 limits the movement of the anti-pinch plate 41 away from the mounting base 40. A spring 42 can be mounted on the positioning rods 45 and pressed between the mounting base 40 and the anti-pinch plate 41. In its natural state, the elastic force of the spring 42 maintains a certain distance between the anti-pinch plate 41 and the mounting base 40.

[0030] A trigger block 410 is provided on the anti-pinch plate 41, and a signal sensor 43 is provided on the fixing seat 40 corresponding to the trigger block 410, such as a micro switch, a diffuse reflection photoelectric sensor, etc.; the signal sensors 43 are preferably multiple. When the user pushes the trigger block 410 on the anti-pinch plate 41 to trigger the signal sensor 43 due to pinching of the hand, the signal sensor 43 sends an electrical signal to the controller 7, and the controller 7 controls the motor 30 to stop rotating in the first time to avoid pinching the user, thereby improving the safety of this product.

[0031] The snap assembly 5 is used to realize the clutch connection between the push plate 32 and the drawer body 2, and includes a connecting seat 50, a flap 51, a snap member 52, a block 53 and a torsion spring 54. Preferably, the snap assembly 5 is in two groups, which are symmetrically arranged on both sides of the rear side panel of the drawer body 2; the connecting seat 50 is fixed to the outer wall of the rear side panel of the drawer body 2 by bolts; the flap 51 is hinged to the connecting seat 50 by a pin and can rotate around the pin; the torsion spring 54 is sleeved on the pin, one end of which abuts the connecting seat 50 and the other end abuts the flap 51. In the natural state, the elastic force of the torsion spring 54 causes the flap 51 to rotate in the direction close to the push plate 32.

[0032] The latch 52 is a hook-shaped protrusion fixed to the free end of the flap 51, with its hook opening facing the push plate 32; the clamping block 53 is a block-shaped protrusion fixed to both sides of the push plate 32, and a step that matches the hook opening is provided on the side facing the latch 52. Under normal conditions, the hook opening of the latch 52 is locked with the step of the clamping block 53, so that the drawer body 2 moves synchronously with the push plate 32.

[0033] The first inclined surface 530 is provided on the side of the block 53 close to the drawer body 2, and the hook end of the fastener 52 is provided with a second inclined surface 520 adapted to the first inclined surface 530. When the push plate 32 pushes the drawer body 2 to close until the fastener 52 contacts the block 53, the two inclined surfaces cooperate to guide the fastener 52 to slide over the block 53 and automatically buckle.

[0034] The linkage assembly 6 includes a transmission rod 60, a front pull plate 61 and a rear pull rod 62. The front pull plate 61 is arranged at the front end of the transmission rod 60, and the rear pull rod 62 is arranged at the rear end of the transmission rod 60. The transmission rod 60 is slidably arranged on the drawer body 2 along the opening and closing direction of the drawer body 2. The front pull plate 61 and the rear pull rod 62 move synchronously with the transmission rod 60. The front pull plate 61 is located between the anti-pinch plate 41 and the fixed seat 40 and is abutted against the front pull plate 61. Preferably, the rear pull rod 62 is a circular shaft, which is located between the flap 51 and the latch 52 and abuts against the flap 51.

[0035] When the anti-pinch plate 41 moves, the trigger block 410 triggers the signal sensor 43, and the controller 7 controls the motor 30 to stop working and the electromagnetic coupling 33, disconnecting the connection between the motor 30 and the screw rod 31, and at the same time the transmission rod 60 drives the flip plate 51 to rotate, and the latch 52 and the block 53 are separated so that the drawer body 2 can move independently relative to the push plate 32.

[0036] If only the sensor is used to trigger the shutdown, the drawer is still rigidly connected to the drive mechanism after the shutdown. The drawer cannot be opened manually or requires a lot of force to open it, which is likely to cause secondary damage. This application forms a dual protection mechanism through the collaborative design of multi-sensor redundant triggering and mechanical linkage instant unlocking, completely solving the hidden danger of finger pinching. Specifically, when the anti-pinch plate 41 moves, the sensor and mechanical unlocking are triggered synchronously. Among them, the signal sensor 43 triggers the motor 30 to stop working, mainly to prevent the motor from continuing to work to close the drawer and causing primary injury to the user. The mechanical unlocking allows the drawer body 2 and the push plate 32 to be directly separated, that is, it can be pulled and pulled like a regular drawer without driving the push plate 32 to move, avoiding secondary injury. At the same time, in scenarios such as motor failure or sensor failure, when the anti-pinch plate 41 is squeezed, it can still be directly pushed to unlock the flap 51 through the mechanical transmission rod 60, ensuring safety in extreme situations.

[0037] Furthermore, the electromagnetic coupling 33 can ensure that the push plate 32 can be pushed back to the initial position at any position, and the normal opening and closing of the drawer body 2 will not be affected by being stuck due to motor failure.

[0038] It should be understood that the normal stop of the motor 30 will not cause the electromagnetic coupling 33 to be disconnected. This is generally done when the motor 30 stops due to an abnormal shutdown such as the anti-pinch component being triggered or the power being cut off. This allows the drawer to be used normally under special circumstances.

[0039] The emergency opening assembly includes an opening rod 8, an emergency opening port 9, an opening shaft 91 and a lock hole 90. The emergency opening port 9 is arranged on the front panel of the drawer body 2. Two lock holes 90 are symmetrically arranged on both sides of the emergency opening port 9. The opening shaft 91 is arranged at one end of the transmission rod 60 close to the emergency opening port 9. The opening shaft 91 is provided with an opening hole 92 close to the emergency opening port 9. The side wall of the opening hole 92 is provided with a track groove 93. The track groove 93 includes a vertical groove 930 and an arc groove 931. The vertical groove 930 extends along the axial direction of the opening hole 92. The arc groove 931 is connected to the end of the vertical groove 930 and extends along the opening hole 92. The opening rod 8 includes a first rod portion 81, a second rod portion 82 and a third rod portion 83 arranged in sequence. The third rod portion 83 is adapted to the opening hole 92 and is provided with a locking block 84 adapted to the track groove 93. Locking strips 85 adapted to the lock hole 90 are provided on both sides of the second rod portion 82. An operating rod 86 is provided at one end of the first rod portion 81 away from the third rod portion 83. When emergency opening is required, the opening rod 8 is inserted along the emergency opening port 9. The third rod portion 83 is inserted into the opening hole 92, and the locking block 84 slides to the bottom along the vertical slot 930. At this time, the second rod portion 82 just passes through the emergency opening 9. The opening rod 8 is rotated 180 degrees by the operating rod 86. The locking block 84 slides to the end along the arc slot 931. At this time, the locking bar 85 is just aligned with the locking hole 90 again. The opening rod 8 is pulled outward. The transmission rod 60 drives the flap 51 to rotate through the rear pull rod 62, so that the latch 52 and the locking block 53 are separated. When the emergency opening state needs to be maintained, it is generally impossible to quickly complete the troubleshooting, but when normal use is required, in order to avoid repeating the operation of the opening rod 8 each time it is opened, it is only necessary to pull out the opening rod 8 so that the second rod portion 82 exits the emergency opening port 9, and then rotate the opening rod 8 through the operating rod 86 to make the locking bar 85 and the locking hole 90 misaligned. At this time, the locking bar 85 and the edge of the locking hole 90 abut against each other to prevent the transmission rod 60 from returning to its position.

[0040] A plurality of medicine storage boxes 10 are evenly arranged around the inner circumference of the drawer body 2. A gravity sensor 11 connected to the controller 7 is provided at the bottom of each medicine storage box 10. A display 12 is provided at the middle junction of the plurality of medicine storage boxes 10. A weight indication module is configured on the display 12 corresponding to each medicine storage box 10. For example, through the RGB three-color indicator light, different light colors will be displayed in real time when taking more or less medicine, giving the user a more intuitive prompt.

[0041] The front and rear ends of the drawer tray 1 are both provided with positioning sensors 16 connected to the controller 7, and the front and rear ends of the drawer body 2 are both provided with positioning members 17. When the drawer body 2 is fully opened or closed, the positioning members 17 move to the positioning sensors 16, and the controller 7 controls the motor 30 to stop working. In addition, the information from the positioning sensors 16 can also be used to determine whether the drawer body 2 is moving normally.

[0042] A closing button 18 connected to the controller 7 is provided on the front panel of the drawer body 2. When pressed, a signal is sent to the controller 7 to control the motor 30 to reverse and drive the drawer body 2 to close.

[0043] Working principle: Normal opening and closing: After the controller 7 receives the opening signal (such as a signal from a PC or mobile terminal), it controls the motor 30 to rotate forward, drives the push plate 32 to slide forward through the screw rod 31, and the push plate 32 drives the drawer body 2 to move synchronously through the buckle assembly 5; when the drawer body 2 is fully opened, the front positioning member 17 triggers the front positioning sensor 16, and the motor 30 stops; when the close button 18 is pressed, the motor 30 reverses, the drawer body 2 closes, the rear positioning member 17 triggers the rear positioning sensor 16, and the motor 30 stops.

[0044] Anti-pinch protection: During the closing process of the drawer body 2, if the user's hand is pinched between the anti-pinch plate 41 and the external cabinet, the anti-pinch plate 41 moves toward the fixing seat 40 under pressure, and the trigger block 410 triggers the signal sensor 43; after receiving the signal, the controller 7 immediately controls the motor 30 to stop and drives the buckle assembly 5 to unlock through the linkage assembly 6, so that the drawer body 2 is disengaged from the push plate 32, and the user can manually open the drawer to avoid being pinched.

[0045] Emergency opening: When the power is off or the motor fails, use the opening rod 8 to insert the emergency opening port 9, release the snap fit through mechanical transmission, and manually push and pull the drawer body 2.

[0046] The gravity sensor 11 detects the weight of the medicine in the medicine box 10 in real time and displays it through the weight indication module of the display 12. When the weight is lower than the threshold, the warning light is on, prompting to replenish the medicine.
