[0044] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0045] A mobile intelligent fresh food delivery cabinet, such as Figure 1 , 2 , 6, comprises an insulation cabinet 101, a storage unit 110 and an automatic retrieval module, wherein the outer wall of the insulation cabinet 101 is made of insulation composite material, the inner cavity of the insulation cabinet 101 is separated from the cold storage chamber by an insulation partition 102, and the storage unit 110 is installed in the cold storage chamber; an insulation door 103 which can be opened or closed is provided on one side of the insulation cabinet 101, and preferably, the top of the insulation door 103 is hinged on the insulation cabinet 101, and the insulation door 103 is driven to rotate by hydraulic telescopic rods arranged on both sides of the insulation cabinet 101, thereby realizing the opening or closing of the insulation door 103. The insulation door 103 is provided with a take-out window 107, through which the articles in the inner cavity of the insulation cabinet 101 can be taken out. The take-out window 107 is also provided with a take-out partition door for closing the take-out window 107. Preferably, the take-out partition door is driven by the second electric push rod 137 to slide up and down along the plane of the insulation door 103. When the second electric push rod 137 drives the take-out partition door to move and completely covers the take-out window 107, the closure of the take-out window 107 is completed, so that the cold air overflows and the articles are difficult to obtain a good refrigeration environment. A group of proximity sensors are also provided on the top of the take-out window 107, so that it can detect whether the take-out partition door of the take-out window is closed. The outside of the insulation door 103 is also provided with an input-output and display module, which includes a touch display screen 105, a barcode scanner 106 and a surveillance camera 108.

[0046] like Figure 7As shown, the storage unit 110 is composed of a plurality of storage compartments 111 arranged in parallel, and the storage compartments 111 of the same storage unit 110 are all in the same plane. Each storage unit 110 has a unique code, each storage compartment 111 has a unique sub-code, and the storage unit 110 is provided with a storage chip for storing detailed information of the storage unit 110. The four walls of the storage compartment 111 are fixed, and the top of the storage compartment 111 is open, which is convenient for placing items in the distribution center. A conveyor belt 109 is arranged under the storage unit 110. Because when the storage unit 110 is placed in the insulation cabinet 101, the top of the storage compartment 111 is close to the conveyor belt 109 or the inner top wall of the insulation cabinet 101, so the open top of the storage compartment 111 will not affect the transportation of the items. A storage compartment door 112 is provided at the bottom of the storage compartment 111. The two sides of the storage compartment door 112 and the two side walls of the storage compartment 111 are rotatably connected by a telescopic rod. Under the drive of the telescopic rod, the storage compartment door 112 hinged to the storage unit 110 can be automatically opened or closed. The opening or closing of the storage compartment door 112 is controlled by a control system, and the opening direction of the storage compartment door 112 is consistent with the transmission direction of the conveyor belt 109. In this way, when the storage compartment door 112 is opened, the objects placed in the storage compartment 111 slide along the opened storage compartment door 112 toward the conveyor belt 109, and after the objects slide onto the conveyor belt 109, they are smoothly transported out along the transmission direction of the conveyor belt 109. Of course, when the storage compartment door 112 is fully opened, the tail end of the storage compartment door 112 does not contact the conveyor belt 109; the storage compartment door 112 will automatically close after being opened for a system-set time. The telescopic rod for driving the storage compartment door 112 to open and close may be an electric push rod or a pneumatic cylinder.

[0047] like Figure 3 , 8As shown, the end of the storage unit 110 is provided with an elastic connector male seat 113, and a partition 102 is provided in the insulation cabinet 101. The partition 102 divides the inner cavity of the insulation cabinet 101 into a cold storage room and an installation room. An elastic connector female seat 115 compatible with the elastic connector male seat 113 is provided on the partition 102 on one side of the cold storage room. A positioning guide column 114 is also provided at the end of the storage unit 110, and a positioning hole is provided on the inner wall of the cold storage room. A retractable locking tongue 116 is provided on the inner wall of the cold storage room, and a locking hole compatible therewith is provided on the storage unit 110, and the locking tongue 116 can be pushed by an electric push rod. The positioning hole on the partition 102 is chamfered to facilitate the insertion of the positioning guide column 110 with a chamfered end into the positioning hole. The locking tongue 116 is used to lock the storage unit 110. The elastic connector male socket 113 is connected to the elastic connection female socket 115 of the insulation cabinet 101 for reading and writing data; the connection method of the elastic connection socket allows successful connection within a certain error range. When the storage unit 110 is successfully electrically connected to the insulation cabinet 101, a group of electric push rods set on the insulation cabinet 101 push the lock tongue 116 into the lock hole on the storage unit 110, which plays a role in fixing the storage unit 110.

[0048] like Figure 2 , 6As shown, the automatic retrieval module includes a plurality of conveyor belts 109 uniformly arranged along the height direction of the heat preservation cabinet 101, a tray 134, a guide rail 135 for the tray 134 to slide up and down, a first motor 133, a gear and a rack 139, a proximity sensor 136 for positioning, and a detection camera 138. The conveyor belt 109 is located below the storage unit 110 and has a certain distance from the storage unit 110 to facilitate the opening of the storage compartment door 112; the transmission direction of the conveyor belt 109 is toward the tray 134. The tray 134 is located in the middle area between the heat preservation door 103 and the conveyor belt 109 of the heat preservation cabinet 101. The tray 134 is provided with a certain slope on the side close to the conveyor belt 109, so that the items can slide onto the tray 134 smoothly and safely. The tray 134 is also provided with a raised stop bar on the side close to the heat preservation door 103 to prevent the items from sliding out of the tray 134. The four corners of the tray 134 are slidably connected to the guide rails 135. The tray 134 is always in a horizontal state during the up and down movement, ensuring that the items can be stably placed on the plane of the tray 134. The first motor 133 is provided on the tray 134, the gear is installed on the rotating shaft of the first motor 133, and the rack 139 is fixed to the inner wall of the heat preservation cabinet 101. When the first motor 133 rotates, it drives the meshing of the gear and the rack 139. The tray 134 can slide up and down along the guide rail 135 under the drive of the driving motor 1. Of course, in order to ensure that the tray 134 can be stably maintained at a fixed height when the first motor 133 is not in a working state, the first motor 133 is a locking motor, that is, when the first motor 133 stops running, the rotating shaft of the first motor 133 will not rotate, so the gear and the rack 139 are meshed, and the tray 134 can be stably maintained at a certain height. Of course, the selection of the first motor 133 is not limited to the selection of the locking motor. Any motor that can achieve the purpose of this application can be implemented in the scope of this application. The proximity sensor 136 is mainly used to sense the position of the tray 134. It is arranged near the end of the conveyor belt 109 and is located on the inner wall of the insulation cabinet 101. The number of proximity sensors 136 is adapted to the number of conveyor belts 109.

[0049] When an item at a certain height needs to be retrieved, the storage compartment door 112 of the corresponding storage compartment 111 is opened, and the item slides onto the corresponding conveyor belt 109, and the tray 134 is driven by the first motor 133 and slides toward the height of the conveyor belt 109. When the tray 134 slides to the position of the proximity sensor 136 corresponding to the conveyor belt 109, the proximity sensor 136 sends a signal to the control system, and the control system controls the first motor 133 to brake, and the tray 134 can be parked at a specified position. A detection camera 138 is also provided on the top of the inner side of the thermal insulation cabinet 101, and the detection camera 138 is facing the tray 134. The control system can compare the image taken by the detection camera 138 to determine whether there is an item on the tray 134.

[0050] During use, when the user inputs the pickup code through the touch display screen 105 or through the barcode scanner 106, the control system sends a command to the storage compartment 111 with the relevant code according to the information of the storage unit chip, opens the corresponding storage compartment door 112, and the items placed in the storage compartment 111 slide along the opened door to the conveyor belt 109. The tray 134 reaches the designated position under the control of the control system, and the conveyor belt 109 drives and transports the items to the tray 134. After reaching the end of the conveyor belt 109, the items slide into the tray 134. The control system compares the images taken by the detection camera 138, and after determining that there are items on the tray 134, the conveyor belt 109 stops; at this time, the tray 134 slides to the back of the access window 107 of the thermal insulation door 103 under the drive of the first motor 133, and the control system controls the access door of the access window 107 to open, and the user takes the items from the access window 107. The control system compares the images taken by the detection camera 138, and after determining that the items on the tray 134 have been taken away, the system controls the access door of the access window 107 to close. The system can also set the opening time of the access door of the access window 107, and the access door automatically closes after the setting time.

By adjusting the telescopic length of the supporting cylinder 130, the supporting height of the insulation cabinet 101 can be adjusted. In order to facilitate the stability of the insulation cabinet 101 during movement, auxiliary wheels 142 are also provided on both sides of the bottom of the insulation cabinet 101. The moving wheels 132 and the auxiliary wheels 142 on each side of the bottom of the insulation cabinet 101 are located on the same center line; in order to ensure that the insulation cabinet 101 can be in a horizontal state when it is on the ground, a distance sensor is also provided at the bottom of the insulation cabinet 101 at the position corresponding to the above-mentioned moving wheels 132. The control system detects its distance from the ground based on the distance sensor, and controls each supporting cylinder 130 to adjust the telescopic amount separately after analysis and calculation to adapt to the uneven ground, thereby ensuring the horizontal placement of the distribution cabinet.

[0054] The present invention also discloses a transport vehicle loaded with the above-mentioned distribution cabinet 1, wherein a fixed connecting frame 2 is provided in the compartment of the transport vehicle. Figure 3 , 4 As shown in Figures 9-17, the fixed connecting frame 2 includes a frame, and both sides of the bottom of the frame are provided with limiting guide rails 201 for cooperating with the moving wheels 132 and the auxiliary wheels 142 to facilitate the sliding in and out of the delivery cabinet 1; because when the delivery cabinet 1 starts to enter the fixed connecting frame 2, it is difficult for the delivery cabinet 1 to be in good cooperation with the fixed connecting frame 2, and there is often a certain deviation angle between the delivery cabinet 1 and the fixed connecting frame 2, so preferably, the limiting guide rail 201 is a U-shaped guide rail, and the U-shaped groove spacing of the limiting guide rail 201 is larger than the width of the moving wheel 132. The U-shaped guide rail can correct the deviation angle between the delivery cabinet 1 and the fixed connecting frame 2, and finally make the delivery cabinet 1 and the fixed connecting frame 2 keep the same direction. A rubber guide rail 202 that cooperates with the rubber wheel 141 is provided in the middle position of the bottom of the frame, so that the rubber wheel 141 can achieve good friction during rotation, thereby ensuring the smooth movement of the delivery cabinet 1; in addition, since it is difficult for the delivery cabinet 1 to be in good cooperation with the fixed connecting frame 2 when the delivery cabinet 1 begins to enter the fixed connecting frame 2, the use of the rubber wheel 141 and the rubber guide rail 202 in cooperation with each other can also avoid the problem of difficulty in meshing between the gear and the rack due to gear rack transmission, thereby ensuring the overall stability of the delivery cabinet 1 in moving out of or into the fixed connecting frame 2.

[0055] like Figure 9-11As shown, L-shaped fixing blocks 203 are arranged on the top of both sides of the frame of the fixed connecting frame 2. The L-shaped fixing blocks 203 are driven to move by another telescopic rod. The L-shaped fixing blocks 203 cooperate with the card slots arranged on the top of both sides of the thermal insulation cabinet 101. Due to the setting of the L-shaped fixing blocks 203 and the L-shaped card slots, the five degrees of freedom of the thermal insulation cabinet 101, namely, up, left, right, front and back, can be limited, thereby playing the role of fixing the thermal insulation cabinet 101. An interface module B204 is provided on one side of the frame of the fixed connecting frame 2, and the interface module B204 includes an elastic connecting female seat 2043 and two front end chamfered positioning guide holes 2041 arranged on the elastic connecting female seat 2043, as well as a charging interface 2042 and a signal interface. The bottom of the elastic connecting female seat 2043 is fixed to the fixed connecting frame 2 through an elastic support seat 2044; since the interface module B204 of the fixed connecting frame 2 is set as an elastic connection, it is convenient to connect with the interface module A120 extending outward from the side wall of the insulation cabinet 101 within a certain error range. In addition, a sensing point 206 is provided on the fixed connecting frame 2 next to the interface module B204. The sensing point 206 cooperates with the positioning sensor embedded next to the interface module A120 on the outer wall of the insulation cabinet 101. When the positioning sensor senses the signal of the sensing point, the insulation cabinet 101 is in the final fixed position. At this time, the control system controls the first electric push rod 119 to move the interface module A120 to the interface module B204 to complete the docking; and the control system also controls the telescopic rod and extends the L-shaped fixing block 203 into the card slot to complete the fixation and connection between the distribution cabinet 1 and the fixed connecting frame 2.

[0056] like Figure 10-11 As shown, the fixed connection frame 2 is equipped with a positioning camera 205 in the middle of the crossbeam near the cab end of the transport vehicle, and laser rangefinders 207 are provided on both sides of the fixed connection frame 2. The positioning camera 205 and the laser rangefinder 207 can be set to perform video-assisted direction correction when the delivery cabinet 1 moves into the carriage. A laser rangefinder is provided on both sides of the crossbeam of the fixed connection frame 2 near the carriage door, which is used to perform accurate distance measurement when the transport vehicle and the delivery cabinet 1 are docked. When the distance values ​​of the delivery cabinet 1 measured by the laser rangefinders on both sides are within the allowable error range, it means that the directions of the fixed connection frame 2 and the delivery cabinet 1 are basically consistent, and the delivery cabinet 1 can be moved into the fixed connection frame 2.

[0057] In the specific work process, such as Figure 12-14As shown, when the delivery cabinet 1 is to be moved out of the fixed connection frame 2, the first electric push rod 119 of the interface module A120 is retracted, the interface module A120 is separated from the interface module B204, and the fixed block 203 of the fixed connection frame 2 is driven by the telescopic rod to leave the card slot of the insulation cabinet 101, and the second motor 140 starts to start, and the delivery cabinet 1 is partially moved out of the fixed connection frame 2. After the distance sensor of the support cylinder at the end of the delivery cabinet 1 that has left the fixed connection frame 2 detects the distance change, the second motor 140 is paused, and the support cylinder with the moving wheel 132 that has left the fixed connection frame 2 is extended to the ground. , the second motor 140 resumes operation, and the delivery cabinet 1 continues to move out of the fixed connecting frame 2 until the distance sensor of the supporting cylinder at the other end of the delivery cabinet 1 detects a change in distance, and the supporting cylinder at the other end of the delivery cabinet 1 also moves out of the fixed connecting frame 2, the second motor 140 pauses, and the supporting cylinder at the other end extends to the ground, and the second motor 140 resumes operation until the delivery cabinet 1 is completely moved out of the fixed connecting frame 2, the second motor 140 stops, and the two supporting cylinders with support plates 131 at the bottom in the middle of the delivery cabinet 1 extend to the ground, and the support plates 131 are used to fasten the delivery cabinet 1.

[0058] When the delivery cabinet 1 is to be moved into the fixed connecting frame 2, the vehicle equipped with the fixed connecting frame 2 uses the alignment camera 205 and the laser rangefinder 207 of the fixed connecting frame 2 for auxiliary adjustment. When the directions of the fixed connecting frame 2 and the delivery cabinet 1 are basically the same, the vehicle moves toward the delivery cabinet 1, and the end of the delivery cabinet 1 enters the fixed connecting frame 2. The rubber wheel 141 of the second motor 140 contacts the rubber guide rail 202 of the fixed connecting frame 2, and the supporting cylinder of the delivery cabinet 1 close to the fixed connecting frame 2 retracts, the second motor 140 starts to start, and the delivery cabinet 1 moves toward the fixed connecting frame 2. When the moving wheel 132 of the supporting cylinder entering the fixed connecting frame 2 contacts the limiting guide rail 201, the distance sensor of the supporting cylinder detects the change in distance, the second motor 140 pauses, the two supporting cylinders with the supporting plates 131 at the bottom in the middle of the delivery cabinet 1 retract, and the second motor 140 resumes operation. At this time, the limiting guide rail 201 of the fixed connecting frame 2 and the moving wheel 132 of the supporting cylinder of the delivery cabinet 1 cooperate with each other to fine-tune the direction of the delivery cabinet 1 so that the direction of the delivery cabinet 1 is consistent with that of the fixed connecting frame 2. Driven by the second motor 140, the delivery cabinet 1 continues to move into the fixed connecting frame 2 until the distance sensor of the supporting cylinder at the other end of the delivery cabinet 1 detects the change in distance, the second motor 140 pauses, the supporting cylinder at the other end of the delivery cabinet 1 retracts, and the second motor 140 resumes operation until the delivery cabinet 1 is completely moved into the fixed connecting frame 2. When the sensor embedded in the outer wall of the delivery cabinet 1 senses the signal of the sensing point 206 of the fixed connecting frame 2, the second motor 140 stops rotating. The first electric push rod 119 of the interface module A120 of the delivery cabinet 1 is started, and the interface module A120 is docked with the interface module B204. When the interface module A120 is successfully docked with the interface module B204, the fixed block 203 of the fixed connecting frame 2 is driven by the telescopic rod to press the card slots set on the top of both sides of the delivery cabinet 1, and the delivery cabinet 1 is fixed on the fixed connecting frame 2.

[0059] Wherein, the transport vehicle is a large truck 3 or a van 4.

[0060] It should be noted that the modules and components that require power drive in the above-mentioned distribution cabinet 1 and the fixed connection frame 2 are all electrically connected to the control system. In addition, the control system is also connected to the cloud service center through remote communication, and the distribution center data, storage unit and storage grid data, transport vehicle data, mobile distribution cabinet data, etc. are all connected to the cloud service center through remote communication, and the data is shared in real time.

[0061] The present invention also provides a mobile intelligent fresh food delivery system, which includes a delivery cabinet 1, a truck 3 and a van 4. The truck 3 and the van 4 are both provided with the above-mentioned fixed connection frame 2, and the delivery cabinet 1 can smoothly slide into the fixed connection frame 2 in the truck 3 and the van 4. At the same time, the truck 3 is provided with a flip-up lifting tailgate 31. During the docking process, Fig.17As shown, the delivery cabinet 1 in the truck 3 is driven by the second motor 140 to move out of the truck 3 to the reversible lifting tailgate 31. The reversible lifting tailgate 31 adjusts its height to match the height of the van 4 compartment. After the van 4 is aligned with the delivery cabinet 1, the van 4 is moved to an appropriate position, and the second motor 140 is started to move the delivery cabinet 1 into the fixed connection frame of the van 4. The specific movement and installation method of the delivery cabinet 1 refers to the specific working process of the delivery cabinet 1 in the above-mentioned transport vehicle, which will not be described here. Therefore, the present invention can provide a safe and hygienic refrigerated distribution service for fresh food, and can efficiently transport it from the distribution center to the distribution point by a large truck. At the distribution point, the delivery cabinet can be moved out of the compartment by itself, and transition to the van or van through the reversible lifting tailgate 31 with a guide rail on the truck, and then distributed to each community by the van or van, avoiding the situation where trucks are restricted on urban roads and cannot be distributed, and taking into account the efficiency and convenience of distribution.
