Description

Technical Field

[0001] The present technical solution relates to the technical field of intelligent cabinets, and particularly refers to an anti-pinch intelligent cabinet. Background Art

[0002] An intelligent vending cabinet is an automated sales device integrating advanced technologies. Through technical means such as the Internet of Things, sensors, and surveillance cameras, it realizes functions such as product display, storage, fast sales, and automatic payment.

[0003] For example, in Chinese Patent CN211177564U, this patent discloses an intelligent freezer, which includes a cabinet body. A refrigerated box is arranged inside the cabinet body. A heat preservation layer is arranged on the outer side of the refrigerated box. A display screen is arranged above the cover plate. A control board is arranged on the front end face of the cabinet body. A temperature sensor is arranged on the inner side face of the refrigerated box. A refrigeration system is arranged on the lower end face of the heat preservation layer. A temperature increase device is arranged on one side of the refrigeration system. A connection hole is arranged on one side of the cabinet body. A drain pipe is arranged on one side of the temperature increase device. The cover plate is movably connected to the upper end face of the cabinet body, and two groups of cover plates are provided in total.

[0004] In actual use of the existing intelligent freezer, users frequently open and close the cover plate to put in and take out items for self-service shopping. To reduce the operation burden of users and prevent users from forgetting to close the cover plate, which may affect the refrigeration and heat preservation effects, an automatic door opening and closing system is usually added. However, the existing automatic door opening and closing action has too fast a response and lacks sufficient safety buffer, which may accidentally pinch the user's hand and cause injury, and the safety performance is poor and needs to be improved. Summary of the Invention

[0005] The present technical solution provides an anti-pinch intelligent cabinet to improve the poor safety performance of the automatic door opening and closing system during actual use.

[0006] The purpose of the present technical solution is achieved as follows:

[0007] An anti-pinch intelligent cabinet includes a cabinet body, and a receiving cavity is formed on its upper end face;

[0008] A cabinet door, which is arranged at the opening of the receiving cavity and is slidably connected to the cabinet body;

[0009] A front panel, which is fixed to the rear side of the upper end face of the cabinet body, and the front panel is provided with an induction device for detection;

[0010] A driving device, which is installed inside the front panel and is used to drive the cabinet door to move between an open position and a closed position;

[0011] The induction device includes a plurality of ultrasonic ranging components. The detection end of the ultrasonic ranging component faces the receiving cavity, and the ultrasonic ranging component controls the operation of the driving device through a control main board.

[0012] With the above technical solution, when the anti-pinch intelligent cabinet is in normal use, items are stored in the accommodation cavity of the cabinet body. The left cabinet door and the right cabinet door are arranged vertically staggered at the opening of the accommodation cavity, enabling horizontal movement towards each other to open or close a single cabinet door. Users can send commands to the control main board by scanning a code, and the driving device will respond immediately, running and controlling the cabinet door to open and close automatically. When the cabinet door is opened, the opening of the accommodation cavity is wide open, and users can obtain items through the opening. When shopping, they need to reach into the cabinet body. At this time, they enter the detection distance range preset by the induction device. The ultrasonic ranging component continuously emits ultrasonic waves. When the ultrasonic waves touch an obstacle, they will be reflected and accurately received by the acoustic ranging component. After processing, the distance of the obstacle is fed back to achieve ranging.

[0013] When the measured distance is less than the set value, the control main board ensures that the driving device is in the closed state, and the cabinet door will not close automatically, triggering the anti-pinch function. After shopping, when the limb leaves the cabinet body, it will be out of the detection range. When the measured distance meets the set value, the cabinet door will automatically close after a short wait. If a hand enters the induction area again during the closing process, the cabinet door will stop closing and run in the reverse direction to reopen until there is no object within the induction range, and then it will continue to close after a short wait. Throughout the process, ultrasonic detection is combined with an immediate response mechanism to optimize the user experience, effectively prevent pinching, ensure the smoothness and convenience of operation, and improve the safety of use.

[0014] Preferably, the ultrasonic ranging component includes a mounting base, a signal output part and a signal induction part arranged in the mounting base;

[0015] The mounting base is fixed on the front panel, and it is provided with a mounting groove. Both the signal output part and the signal induction part are installed in the mounting groove;

[0016] The receiving end of the signal induction part is used to receive the signal output by the output end of the signal output part.

[0017] With the above technical solution, the signal output part and the signal induction part are installed in the mounting groove of the mounting base. The mounting base serves as the mounting foundation and is fixedly connected to the front panel. The signal output part is responsible for generating and sending ultrasonic signals, making the signal output by the output end accurately directed to the target area. The distance parameter for triggering anti-pinching by ultrasonic ranging is set on the main control, and this trigger distance is set as the edge of the freezer (obstacle). At this time, the working ends of both the signal output part and the signal induction part face the accommodation cavity, enabling the ultrasonic waves to touch the edge of the freezer and be reflected. The receiving end of the signal induction part just receives the reflected wave signal, and the control main board calculates the distance and judges, thereby realizing the normal operation of the anti-pinching function.

[0018] Preferably, the conical angle at which the ultrasonic ranging component emits ultrasonic waves towards the front side edge of the cabinet body is 12° - 18°.

[0019] Through the above technical solution, a conical angle is formed between the emission path and the reflection path, and the included angle is set within a range value of 12°-18°. Based on the comprehensive acoustic principle and actual application requirements, it is ensured that the ultrasonic wave output from the output end of the signal output part is received by the receiving end of the signal receiving part after touching the reflection, thereby improving the detection accuracy.

[0020] Preferably, at least two groups of combinations of the signal output part and the signal induction part are provided on the mounting base, and they are respectively arranged at both ends of the mounting base along the length direction.

[0021] Through the above technical solution, a combination of a signal output part and a signal induction part realizes the emission and reception of signals. By increasing the number of combinations and distributing them at both ends of the mounting base, the emission and reception range of ultrasonic signals is significantly expanded, the area that can be covered by the anti-pinch distance measurement is further expanded, the detection blind area is reduced, and the safety is further improved.

[0022] Preferably, there are two cabinet doors, and several ultrasonic distance measurement components are arranged along the sliding direction of the corresponding cabinet door.

[0023] Through the above technical solution, multiple ultrasonic distance measurement components cooperate to form a detection network, effectively covering the area in front of the two cabinet doors.

[0024] Preferably, a cabinet opening frame is formed around the opening of the accommodation cavity at the upper end of the cabinet body, and a mounting frame is provided on the cabinet opening frame, and the driving device is arranged on the mounting frame;

[0025] The driving device includes a driving member, two belt pulleys and a transmission belt tensioned between the two belt pulleys;

[0026] A connecting member is provided on the transmission belt, a connecting plate is fixed to the cabinet door, the connecting plate is connected to the connecting member, and the driving member drives the transmission belt through the cooperation of the two belt pulleys to drive the cabinet door.

[0027] Through the above technical solution, both the mounting frame and the front panel are installed on the annular frame, so that it is located at the rear side above the cabinet door. The mounting frame is used for the fixed installation of the driving device. The two belt pulleys are arranged at both ends of the mounting frame along the sliding direction of the cabinet door. One of the belt pulleys is arranged on the output shaft of the driving member, and the driving member drives the belt pulley to rotate. Based on the transmission belt being tensioned between the two belt pulleys, a stable transmission system is formed. Through the belt drive of the transmission belt, a closed-loop circular motion is formed between the two belt pulleys to ensure the stability of synchronous rotation. The connecting member is fixed to the transmission belt and connected to the connecting plate, and the two cooperate to realize the transmission belt driving the connecting plate. Based on the connection between the connecting plate and the cabinet door, the movement of the cabinet door is further realized.

[0028] Preferably, the driving device is provided with a transmission bearing, which is located between the mounting bracket and the driving member, and the transmission bearing is arranged on the output shaft of the driving member.

[0029] Through the above technical solution, the output shaft of the driving member is relatively long. The transmission bearing is sleeved on the output shaft of the driving member to provide accurate and stable guidance for the rotation of the output shaft, improve the smoothness of rotation, avoid the bending of the output shaft of the driving member affected by external resistance, and ensure the coaxiality of the output shaft.

[0030] Preferably, the mounting bracket is provided with a first proximity switch and a second proximity switch, and the first proximity switch and the second proximity switch are arranged on the mounting bracket and distributed along the sliding direction of the cabinet door;

[0031] The connecting plate has a trigger piece, and the connecting plate drives the trigger piece to slide;

[0032] When the first proximity switch is triggered, the driving device stops so that the cabinet door is in the closed state. When the second proximity switch is triggered, the driving device can stop to make the cabinet door in the open state.

[0033] Through the above technical solution, both the first proximity switch and the second proximity switch can be triggered by the trigger piece. When the trigger piece moves to the position of the first proximity switch and triggers it, the system detects that the cabinet door has reached the closed position. After receiving the signal from the first proximity switch, the driving device stops running to ensure that the cabinet door will not continue to move excessively closed. On the contrary, when the trigger piece moves to the position of the second proximity switch and triggers it, the system detects that the cabinet door has reached the open position, and the driving device stops running again to ensure that the cabinet door will not continue to move excessively open, prevent damage caused by collision, improve the accuracy and safety of opening and closing the cabinet door, and improve the reliability of operation.

[0034] Preferably, the front panel is provided with a control button, and the control button is connected to the control main board to control the operation of the driving member.

[0035] Through the above technical solution, the control button on the front panel is connected to the control main board. It is set as a button switch for closing the door. After taking goods from the accommodation cavity, the control button can be directly pressed to operate the control main board in advance to close the cabinet door, providing an active closing method for the cabinet door, without waiting for it to close automatically, thereby optimizing the use experience and improving the flexibility of use.

[0036] Preferably, the front panel is provided with external cameras. There are several external cameras, and the lens ends of the corresponding external cameras are inclined downward towards the corresponding cabinet doors for recording items.

[0037] Through the above technical solution, the camera can obtain an overview of the entire item retrieval area. When the user takes out an item from the accommodation cavity, the camera transmits the captured image data to the control system or the central processing unit to confirm the customer's operation and the purchase process, thereby realizing automatic settlement and improving the usage efficiency.

[0038] Preferably, the front panel is further provided with an inner camera, which is fixed on the inner side of the front panel away from the outer camera, and the lens end of the inner camera is inclined downward towards the accommodation cavity.

[0039] Through the above technical solution, the inner camera records the storage of items and records item information. It is used in conjunction with the outer camera to ensure that any angle of taking or replenishing goods can be clearly recorded and distinguished, which helps to further reduce blind spots and further improve the accuracy and comprehensiveness of image capture.

[0040] The prominent and beneficial technical effects of this technical solution compared with the prior art are:

[0041] 1. In this technical solution, an induction device for detection is provided on the front panel. The induction device includes a number of ultrasonic ranging components, and their detection ends all face the accommodation cavity. The ultrasonic ranging components measure distances through ultrasonic waves and are connected to the control main board to control the operation of the driving device. According to the distance measurement comparison, it is judged whether automatic door closing is required to prevent pinching and ensure the smoothness and convenience of operation and improve safety;

[0042] 2. In this technical solution, the ultrasonic ranging components are inclined towards the cabinet door edge at an inclination angle of 12° - 18°, ensuring that both the output end of the signal output part and the receiving end of the signal receiving part face the cabinet edge obliquely, so that the ultrasonic waves output by the signal output part can touch the obstacle, and the signal receiving part can correspondingly cooperate to receive, thereby improving the accuracy and comprehensiveness of detection.

Detailed Embodiment

[0049] The following further elaborates on the detailed embodiments of the present technical solution in conjunction with the accompanying drawings.

[0050] Embodiment:

[0051] Refer to Figure 1 , an anti-pinch intelligent cabinet, including a cabinet body 1. The cabinet body 1 is in the form of a cuboid horizontal cabinet structure and can be stably placed on the ground. An accommodation cavity 2 is correspondingly opened inside the cabinet body 1, and its opening is located on the upper end face of the cabinet body 1. Items can be stored and taken out of the accommodation cavity 2 through the opening. A cabinet opening frame 9 is formed around the opening of the accommodation cavity 2 at the upper end of the cabinet body 1, and it is arranged at the edge of the cabinet body 1. The cabinet body 1 is provided with a cabinet door 3. The cabinet door 3 is made of transparent glass material. In this embodiment, there are two cabinet doors 3, specifically including the left cabinet door 3 and the right cabinet door 3. Both cabinet doors 3 are located inside the cabinet opening frame 9 and can completely cover the opening of the accommodation cavity 2. Each cabinet door 3 is slidably connected to the cabinet body 1. By arranging the two cabinet doors 3 to stagger up and down, the sliding paths are staggered from each other, and they can be independently opened or closed unilaterally, reducing interference.

[0052] Refer to Figure 2 , the cabinet body 1 is provided with a front panel 4, which is located at the rear side above the cabinet body 1 and is erected on the cabinet door 3, and both of its ends are fixed to the corresponding cabinet opening frame 9. In this embodiment, a screen is equipped on the front side of the front panel 4 shown, and it is preferably a 21.5-inch advertising screen for setting information display.

[0053] A driving device 5 is installed inside the front panel 4, and a mounting rack 10 is also fixed on the cabinet opening frame 9. The driving device 5 is specifically fixedly installed on the upper end face of the mounting rack 10. There are two driving devices 5, and the two driving devices 5 are arranged in one-to-one correspondence with the two cabinet doors 3, respectively driving the corresponding cabinet doors 3 to move and switch between the open position and the closed position; there are also two control main boards 7 on the mounting rack 10, which are respectively connected to the two driving devices 5 in one-to-one correspondence. In this example, it is shown that the front panel 4 is provided with a QR code, and the user scans the QR code to transmit the information instruction for opening the cabinet door 3 to the control main board 7, so that the control main board 7 correspondingly controls the driving device 5 to open the cabinet door 3 for shopping use.

[0054] See Figure 5 Figure 5 , each driving device 5 includes a driving member 51, two belt pulleys 52 and a transmission belt 53. The driving member 51 is preferably a motor. In this example, the driving member 51 has a worm and worm gear structure. After the driving member 51 is installed, the driving device 5 is further provided with a transmission bearing 13. The transmission bearing 13 is located between the driving member 51 and the mounting bracket 10. The output shaft of the driving member 51 passes downward through the mounting bracket 10. The transmission bearing 13 is arranged on the output shaft of the driving member 51. Both belt pulleys 52 are located below the mounting bracket 10. One of the belt pulleys 52 is arranged on the output shaft of the driving member 51 and is coaxially arranged with the transmission bearing 13 to ensure coaxiality and guide the rotation of the output shaft, realizing rotation around the output shaft. The two belt pulleys 52 are arranged at intervals along the length direction of the mounting bracket 10. The position of the other belt pulley 52 is in the middle of the mounting bracket 10. The rotation axes of the two belt pulleys 52 are parallel to each other. The transmission belt 53 is tensioned between the two belt pulleys 52. The driving member 51 drives one of the belt pulleys 52 to rotate, so that the power is transmitted through the transmission belt 53 to drive the other belt pulley 52 to cooperate.

[0055] A connecting member 11 is provided on each transmission belt 53. The connecting member 11 is fixed to the transmission belt 53 by fastening screws, so as to move along with the transmission belt 53. Two connecting plates 12 are fixed to the two cabinet doors 3. The two connecting plates 12 and the two connecting members 11 are arranged in one-to-one correspondence. The lower end of the corresponding connecting member 11 is bolt-fixed to the corresponding connecting plate 12. Based on the fact that the connecting plate 12 is fixed to the cabinet door 3, the transmission belt 53 is thus driven to drive the cabinet door 3 to slide.

[0056] The mounting bracket 10 is provided with a first proximity switch 17 and a second proximity switch 18. In this embodiment, two sets of the first proximity switch 17 and the second proximity switch 18 are provided corresponding to the two cabinet doors 3 respectively. Each proximity switch is installed on the upper end face of the mounting bracket 10 and is connected to the control panel. The two proximity switches in each group are distributed at both ends along the sliding direction of the corresponding cabinet door 3, corresponding to the open position and the closed position of the cabinet door 3 respectively.

[0057] Each connecting plate 12 has a trigger piece 19. The trigger piece 19 extends downward toward the position of the proximity switch. In this example, it shows the situation that the trigger will be triggered when the distance between the trigger piece 19 and the corresponding proximity switch is less than 4 mm. When the trigger piece 19 moves close to the first proximity switch 17, the first proximity switch 17 is triggered, and the control panel correspondingly controls the driving member 51 in the driving device 5 to stop. At this time, the cabinet door 3 is exactly in the fully closed state. When the trigger piece 19 moves close to the second proximity switch 18, the second proximity switch 18 is triggered, and the control panel correspondingly controls the driving member 51 in the driving device 5 to stop. At this time, the cabinet door 3 is in the open state.

[0058] See Figure 3 andFigure 4 The front panel 4 is provided with a sensing device. The sensing device includes a plurality of ultrasonic ranging components 6. There are four of them. Every two ultrasonic ranging components 6 correspond to one cabinet door 3. The two ultrasonic ranging components 6 are arranged along the sliding direction of the corresponding cabinet door 3. Each ultrasonic ranging component 6 is fixed to the inner wall on the front side of the front panel 4.

[0059] Each ultrasonic ranging component 6 includes a mounting base 61, a signal output part 62 and a signal sensing part 63. Among them, one signal output part 62 needs to be combined with one signal sensing part 63 for cooperative use. There are at least two groups of combinations of the signal output part 62 and the signal sensing part 63 arranged on the mounting base 61. In this embodiment, the case of two groups is shown. And the two groups of combinations of the signal output part 62 and the signal sensing part 63 are respectively arranged at both ends of the mounting base 61 along the length direction. The mounting base 61 is bolted to the inner wall of the front panel 4. The mounting base 61 is provided with a mounting groove 8, and the mounting groove 8 is opened on the side of the mounting base 61 facing away from the inner wall of the front panel 4. The signal output part 62 and the signal sensing part 63 are both installed in the mounting groove 8. The output end of the signal output part 62 and the receiving end of the signal sensing part 63 both pass through the through holes of the mounting base 61 and the through holes of the front panel 4 and face above the cabinet door 3.

[0060] The output end of the signal output part 62 can continuously emit ultrasonic waves into the conical surface of the included angle. The ultrasonic ranging trigger anti-pinch distance can be set on the main control, and the trigger distance is set as the distance to the edge of the cabinet body 1 to eliminate the error caused by installation. When its emission path can just make the ultrasonic wave touch the edge of the cabinet body 1, the ultrasonic wave rebounds after hitting the obstacle (the edge of the cabinet body 1) and is reflected along another path to the receiving end of the corresponding signal sensing part 63, as Figure 1 shown. The emission path and the reflection path form a conical surface included angle with an angle of α, α = 12° - 18°, preferably 15°. After processing, the distance of the obstacle is fed back to realize the ranging function. The ultrasonic ranging component 6 is connected to the controller to control the operation of the driving device 5. When the ranging value is less than the set value, the control main board 7 ensures that the driving device 5 is in the closed state, and the cabinet door 3 will not automatically close, triggering the anti-pinch function. After the limb leaves the cabinet body 1, it gets out of the detection range. When the ranging conforms to the set value, the cabinet door 3 automatically closes after a short wait.

[0061] The front panel 4 is also provided with two control buttons 14. The two control buttons 14 are respectively connected to two control panels. Each control button 14 is fixed on the front end face of the front panel 4. By pressing the corresponding control button 14, the corresponding cabinet door 3 can be controlled to close, realizing the active closing of the cabinet door 3.

[0062] The front panel 4 is provided with a plurality of external cameras 15. There are two external cameras 15, and the two external cameras 15 correspond to the two cabinet doors 3 one by one. The two external cameras 15 are both fixed on the front inner wall of the front panel 4, and the lenses of the external cameras 15 are both inclined downward towards the positions of the corresponding cabinet doors 3, for videotaping the removal of items in the corresponding accommodation cavity 2. The front panel 4 is provided with a plurality of internal cameras 16. There are two internal cameras 16, which are arranged corresponding to the two cabinet doors 3 one by one. The two internal cameras 16 are both fixed on the rear inner wall of the front panel 4, and the lenses of the internal cameras 16 are both inclined downward towards the corresponding accommodation cavity 2. The corresponding internal camera 16 cooperates with the corresponding external camera 15, and the shooting ranges are mutually compensated and coordinated to improve the shooting coverage range.

[0063] The specific working process of this solution is as follows:

[0064] In this technical solution, the left cabinet door 3 and the right cabinet door 3 are arranged in a staggered manner up and down at the opening of the accommodation cavity 2, and the single cabinet door 3 is opened or closed by moving horizontally towards each other. When in use, an instruction is sent to the control main board 7, and the driving device 5 immediately responds and drives the cabinet door 3 to open and close automatically. When the cabinet door 3 is opened, the accommodation cavity 2 is opened to facilitate the user to obtain items through the opening. The user needs to reach into the cabinet body 1 to pick up the goods. At this time, it enters the detection distance range preset by the induction device. The signal output part 62 continuously emits ultrasonic waves. The ultrasonic waves will be reflected when touching an obstacle and are accurately received by the signal induction part 63. After processing, the distance of the obstacle is fed back to achieve distance measurement. When the measured distance is less than the set value, the control main board 7 ensures that the driving device 5 is in a closed state, and the cabinet door 3 will not automatically close, realizing the function of preventing pinching hands. After shopping, when the limb leaves the cabinet body 1 and makes it out of the detection range, when the measured distance meets the set value, the cabinet door 3 will automatically close after a short wait. If a hand enters the induction area again during the closing process, the cabinet door 3 will stop closing and run in the reverse direction to reopen until there is no object within the induction range, and then it will continue to close, effectively preventing pinching hand incidents and ensuring the smoothness and convenience of the operation and improving the safety of use.
