Technical Field

[0001] The present invention relates to the technical field of cargo transportation devices, and in particular to a convenient delivery system for building exterior walls. Background Art

[0002] The express delivery and food delivery industries are booming. Smaller deliveries to high-rise buildings require delivery drivers to walk up stairs or take elevators. This wastes time and energy in buildings without walk-ups, making it particularly inconvenient for those with mobility issues. Taking elevators also takes a long time and is inefficient during peak hours, such as rush hour.

[0003] In the prior art, Chinese invention patent application CN111099481A discloses a small-sized automatic high-rise freight elevator, comprising a wire traction machine, a high-rise building, a freight elevator housing, a balcony, a second touch screen, an electric lift door, an exit, a first proximity sensor, a first touch screen, a freight elevator door, a cylindrical rod, a cargo box, a horizontal conveyor, a freight elevator floor, a lifting lug, a second proximity sensor, and a third proximity sensor. The wire traction machine is mounted on the high-rise building at the top of the freight elevator housing. The freight elevator housing is provided with a plurality of exits, each corresponding to the number of balconies, facing each other. The electric lift door is mounted at each exit. This invention enables automated transportation of goods from downstairs to upstairs, and similarly, from upstairs to downstairs. It offers numerous advantages, significantly improving the convenience of freight transportation for residents and also greatly facilitating the express delivery and takeout industries.

[0004] However, the above-mentioned transport elevator is based on the existing elevator with reduced size and increased functions. It still occupies a large amount of outdoor space and has a great impact on the building facade. At the same time, its elevator goes directly to the residents' balcony. Although it improves convenience, there are certain safety and privacy issues. Summary of the Invention

[0005] The technical problem to be solved by this invention is to provide a convenient delivery system for building exterior walls. Through the cooperation of vertical tracks and a transport trolley, cargo can be automatically transported from the lower floor to a designated floor, eliminating the need for manual stair climbing or waiting for an elevator. The vertical tracks are arranged along the building's exterior wall, minimizing the use of outdoor space. The cargo is delivered to a storage location near a window by a conveyor mechanism, achieving both convenience and safety.

[0006] In response to the above technical problems, the technical solution provided by the present invention is a convenient delivery system for the exterior wall of a building, including a vertical track, a conveying trolley, a driving mechanism, a placement position and a control panel. The vertical track is used to be set on the exterior wall of the building where windows are provided. The conveying trolley is set on the vertical track along a vertical sliding motion. The driving mechanism drives the conveying trolley to move on the vertical track. The conveying trolley is provided with a placement position, which is used to place goods. The placement position is used to be set on the side of the exterior wall of the building close to the window. The placement position corresponds one-to-one to the resident. The conveying trolley is also provided with a conveying mechanism, which is used to transport the goods in the placement position to the placement position. The control panel controls the conveying trolley to move to the designated floor according to the goods information, and controls the conveying mechanism to transport the goods to the designated placement position.

[0007] Furthermore, a sliding groove extending vertically is provided in the vertical track, and a sliding mechanism is provided on the side of the conveying trolley facing the vertical track, and the sliding mechanism is slidably provided in the sliding groove.

[0008] Furthermore, the slot of the sliding slot is symmetrically provided with two slot plates, and an opening is formed between the two slot plates. The sliding mechanism includes a connecting plate and a sliding wheel. The connecting plate is provided on the inner side of the conveying trolley and passes through the opening and extends into the sliding slot. Two sets of sliding wheels are symmetrically provided along the left and right directions on one side of the connecting plate that extends into the sliding slot. The sliding wheels roll vertically on the slot plates on the corresponding sides.

[0009] Furthermore, baffles extending inwards are provided on opposite sides of the two slot plates, and the two baffles are located between the two groups of sliding wheels.

[0010] Furthermore, the driving mechanism includes a driving gear, a driving tooth groove and a driving motor. The driving gear is symmetrically arranged on the left and right sides of the conveying trolley, and its axis extends in the left and right directions. The driving motor drives the driving gear to rotate. The driving tooth grooves are arranged on the groove plate at equal intervals along the vertical direction. The position of the driving tooth groove corresponds to the position of the driving gear, and the interval between adjacent driving tooth grooves is adapted to the interval between adjacent teeth of the driving gear.

[0011] Furthermore, a placement plate extending vertically is provided on the side of the conveying trolley facing away from the vertical track, and a plurality of placement hooks are respectively provided on the left and right sides of the placement plate, and the placement hooks constitute the placement position.

[0012] Furthermore, the conveying mechanism includes a multi-degree-of-freedom robotic arm arranged on the conveying trolley, and a robotic arm is arranged on the multi-degree-of-freedom robotic arm. The multi-degree-of-freedom robotic arm drives the robotic arm to grab the goods and place them in the placement position.

[0013] Furthermore, the placement location includes a placement hook, and the placement hook is arranged near the resident's window.

[0014] Furthermore, a sun and rain protection plate is provided above the placement position.

[0015] Furthermore, a support plate is provided at the lower end of the vertical track, and a reinforcement plate is provided at the lower end of the support plate. The support plate and the reinforcement plate are fixedly installed on the outer wall of the building. The lower end of the vertical track is supported on the support plate, and a damping spring is provided at the upper end of the support plate corresponding to the position of the conveying trolley.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The coordination of vertical tracks and transport trolleys enables the automated transport of goods from the lower floor to the designated floor, eliminating the need for manual stair climbing or elevator waiting. This solves the time-consuming delivery issues of buildings without walk-ups and elevator congestion during peak hours, improving delivery efficiency. The vertical tracks are arranged along the building's exterior walls, minimizing the need for outdoor space and minimizing the impact on the building's facade. Goods are delivered to a "retention area" near a window via a conveyor mechanism, rather than directly onto a balcony. This reduces the risk of outsiders accessing residents' private spaces through the delivery system, ensuring a balanced approach to convenience and safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application: Specific embodiment 1:

[0030] In this embodiment, if Figure 1 As shown, the left and right directions are the horizontal spacing directions of the two sunscreen and rainscreen panels 72 .

[0031] refer to Figures 1 to 9 The present invention provides a convenient delivery system for building exterior walls, comprising a vertical track 4, a transport trolley 5, a drive mechanism 6, a placement position 7, and a control panel 8. The vertical track 4 is used to be installed on the exterior wall 2 of a building 1 having windows 3, and is fixed to the exterior wall 2 by means of fixed anchor bolts 11. The transport trolley 5 is vertically slidably installed on the vertical track 4, and the drive mechanism 6 drives the transport trolley 5 to move on the vertical track 4. The transport trolley 5 is provided with a placement position 55 for placing goods, and the placement position 7 is used to be installed on the side of the exterior wall 2 of the building 1 near the window 3. The number and position of the placement positions 7 correspond one-to-one to the windows 3 on the exterior wall 2 of each resident, and each resident is provided with a set of placement positions 7 at their window 3.

[0032] The transport trolley 5 is also provided with a transport mechanism 51, which is used to transport the goods from the placement position 55 to the placement position 7. The control panel 8 controls the transport trolley 5 to move to the designated floor according to the goods information, and controls the transport mechanism 51 to transport the goods to the designated placement position 7. After the goods are delivered to the placement position 7, the resident takes the goods from the window 3 into the house, completing the delivery operation of the goods.

[0033] With such a setting, through the cooperation of the vertical track 4 and the conveying trolley 5, the automatic transportation of goods from downstairs to the designated floor is realized, eliminating the need for manual climbing of stairs or waiting for the elevator, solving the problems of time-consuming delivery in buildings without elevators and elevator congestion during peak hours, and improving the delivery efficiency. The vertical track 4 is arranged along the outer wall 2 of the building 1, reducing the occupation of outdoor space and minimizing the impact on the building facade. The goods are sent to the "placement position 7" near the window 3 through the conveying mechanism 51 instead of directly entering the balcony, avoiding the risk that external personnel can access the private space of the residents through the delivery system, and taking into account both convenience and safety.

[0034] Preferably, in this embodiment, as Figure 1 , 2 , shown in Figures 3, 4, and 5, a sliding groove 41 extending vertically is provided in the vertical track 4, and a sliding mechanism 56 is provided on one side of the conveying trolley 5 facing the vertical track 4. The sliding mechanism 56 is slidably arranged in the sliding groove 41. Specifically, two groove plates 42 are symmetrically arranged at the notch of the sliding groove 41, and an opening 44 is formed between the two groove plates 42.

[0035] The sliding mechanism 56 includes a connecting plate 57 and sliding wheels 59. The connecting plate 57 is arranged inside the conveying trolley 5 and penetrates through the opening 44 and extends deep into the sliding groove 41. On one side of the connecting plate 57 extending deep into the sliding groove 41, two groups of sliding wheels 59 are symmetrically arranged in the left-right direction, and the sliding wheels 59 roll vertically on the corresponding groove plate 42.

[0036] [[ID=1十三]]Preferably, as Figure 5 , 7 shown, in this embodiment, baffle plates 43 extending inward are provided on the opposite sides of the two groove plates 42. The cross-section of the entire sliding groove 41 is "concave"-shaped. In the left-right direction, the two baffle plates 43 are located between the two groups of sliding wheels 59. The baffle plates 43 are used to limit the sliding wheels 59 in the left-right direction, preventing the sliding wheels 59 from slipping out and ensuring stable sliding.

[0037] Specifically, in this embodiment, as Figure 8 shown, the connecting plate 57 is a "卜"-shaped plate. As Figure 7 shown, a connecting shaft 58 is provided on each of the upper and lower sides of the inner end of the connecting plate 57. The connecting shafts 58 are symmetrically arranged in the left-right direction through the connecting plate 57. A group of sliding wheels 59 are respectively rotatably arranged at the left and right ends of the connecting shaft 58. The two sliding wheels 59 on the same side in the left-right direction form a group of sliding wheels 59. Four sliding wheels 59 are used to increase stability.

[0038] Specifically, in this embodiment, a large-diameter section 510 is further provided on the connecting shaft 58 at a position between the connecting plate 57 and the corresponding baffle plate 43. The baffle plate 43 is clamped between the large-diameter section 510 and the sliding wheel 59 for left-right limiting to maintain the stable movement of the conveying trolley 5.

[0039] In this embodiment, preferably, the driving mechanism 6 includes a driving gear 61, a driving tooth groove 62 and a driving motor, wherein Figure 7 、 8 As shown, a set of driving gears 61 are rotatably provided on the left and right sides of the conveying trolley 5 , and the two driving gears 61 are symmetrically arranged in the left-right direction, and the rotation axes of the two driving gears 61 extend along the left-right direction.

[0040] The drive motor (not shown in the figure) is arranged inside the conveying trolley 5. Specifically, the two drive gears 61 are connected by a drive shaft (not shown in the figure). The drive shaft is arranged inside the conveying trolley 5 and extends laterally. Specifically, the two ends of the drive shaft respectively pass through the left and right side walls of the conveying trolley 5, and the position where the drive shaft contacts the conveying trolley 5 rotates with the side walls of the conveying trolley 5. The two drive gears 61 are respectively fixed at both ends of the drive shaft. Inside the conveying trolley 5, a first gear (not shown in the figure) and a second gear (not shown in the figure) are arranged between the drive shaft and the drive motor. The first gear is fixed on the motor shaft of the drive motor, and the second gear is fixed on the drive shaft. The first gear and the second gear are meshed and transmitted. The drive motor drives the first gear to rotate, the first gear drives the second gear to rotate, and then drives the drive shaft to rotate, thereby driving the two drive gears 61 to rotate.

[0041] The driving tooth grooves 62 are arranged at equal intervals along the vertical direction on the groove plate 42. The positions of the driving tooth grooves 62 correspond to the positions of the driving gears 61, and the intervals between adjacent driving tooth grooves 62 are adapted to the intervals between adjacent teeth of the driving gear 61. When the driving gear 61 rotates, it is sequentially engaged in the driving tooth grooves 62 to drive the conveying trolley 5 to move.

[0042] In this embodiment, the driving gear 61 is disposed between two sliding wheels 59 spaced apart in the vertical direction. In the left-right direction, the sliding wheel 59 is disposed between the driving gear 61 and the baffle 43 to avoid motion interference.

[0043] In this embodiment, preferably, Figure 7 、 8 As shown, a vertically extending placement plate 54 is provided on the side of the transport trolley 5 facing away from the vertical track 4. Multiple placement hooks are provided on the left and right sides of the placement plate 54, forming placement positions 55. Items to be delivered are hooked onto the placement hooks for transport. Using multiple placement positions 55, multiple items can be delivered simultaneously.

[0044] Specifically, such as Figure 6As shown, the conveying mechanism 51 includes a multi-degree-of-freedom robotic arm 52 provided on the conveying trolley 5. In this embodiment, the multi-degree-of-freedom robotic arm 52 is rotatably provided on the top of the conveying trolley 5. A manipulator 53 is provided at one end of the multi-degree-of-freedom robotic arm 52 facing away from the conveying trolley 5. The multi-degree-of-freedom robotic arm 52 drives the manipulator 53 to grab the goods in the placement position 55 and place them in the placement position 7. The specific multi-degree-of-freedom robotic arm 52 and the manipulator 53 that can be opened and closed for grabbing are common knowledge well known to those skilled in the art, and their structure and working principle will not be described in detail here. In this embodiment, the conveying trolley 5 can be powered by a cable or a power battery. When powered by a power battery, a battery compartment is provided on the conveying trolley 5, and a detachable battery is provided in the battery compartment. The battery can be quickly replaced to ensure power supply. The multi-degree-of-freedom robotic arm 52 is connected to the control panel 8 by signal, receives instructions from the control panel 8 and executes them.

[0045] In this embodiment, if Figure 1 、 9 As shown, placement position 7 includes a hook 71, located near a resident's window 3. A sunscreen 72 is installed above placement position 7. During delivery, the multi-degree-of-freedom robotic arm 52 controls the manipulator 53 to remove the cargo hooked on placement position 55 and reattach it to placement position 7, completing the delivery. The placement of hook 71 near window 3 allows residents to reach for their cargo without leaving the house. The sunscreen 72 protects the cargo from exposure to the sun or moisture, ensuring its integrity.

[0046] In this embodiment, a support plate 9 is provided at the lower end of the vertical track 4, and a reinforcing plate 10 is provided at the lower end of the support plate 9. The support plate 9 and the reinforcing plate 10 are fixedly installed on the outer wall 2 of the building 1. The lower end of the vertical track 4 is supported on the support plate 9, and a damping spring 12 is provided at the upper end of the support plate 9 corresponding to the position of the conveying trolley 5. On the one hand, it prevents the conveying trolley 5 from escaping from the lower end of the vertical track 4, and on the other hand, it prevents the conveying trolley 5 from having hard contact with the support plate 9, thereby improving safety.

[0047] Working process of this application:

[0048] In this embodiment, the control panel 8 is set with three control commands, namely, delivering, picking up, and changing.

[0049] The delivery process is as follows: place the item on the hook - select delivery - select room number - select OK.

[0050] Specifically, in this embodiment, the number and location of placement positions 55 correspond to room numbers. The placement positions 55 (i.e., placement hooks) are numbered, and these numbers correspond to room numbers. The control panel 8 selects the room number to be delivered and hooks the cargo onto the corresponding placement hook. After placing the cargo onto the placement position 55, the delivery button is clicked, and the drive motor drives the transport trolley 5 vertically along the vertical track 4. When the transport trolley 5 reaches the designated floor, the multi-degree-of-freedom robotic arm 52 drives the manipulator 53 to grab the cargo from the corresponding placement hook and hook it onto the placement hook 71 next to the window 3 of the room number on the corresponding floor, completing the delivery. After the delivery is complete, the system returns to standby.

[0051] The retrieval process: Select "retrieve item" - Select "room" - Select "confirm." Specifically, the drive mechanism 6 drives the transport cart 5 to the window 3 of the corresponding room number. The multi-degree-of-freedom robotic arm 52 controls the manipulator 53 to grab the item from the placement hook 71 of the room's placement position 7 and place it on the corresponding hook. The transport cart 5 then moves down along the vertical track 4 to its initial position, where a person below removes the item from placement position 55.

[0052] Change process: When an operation error is found, the change process can be used, that is, select Change - select Room 1 - select Room 2 - select Confirm, and the multi-degree-of-freedom robotic arm 52 will automatically go to the placement hook 71 of Room 1 to grab the item and put it down at the placement hook 71 of Room 2.

[0053] Of course, in other embodiments, the room numbers and the placement hook numbers may not correspond one-to-one. In this case, in the control panel 8 system, when delivering goods, the room number is first selected, and then the placement hook number is selected. The room number and the placement hook number are matched, and the goods are then hooked on the placement hook for delivery. When picking up goods, the drive mechanism 6 first drives the transport trolley 5 to the window 3 of the corresponding room number. The multi-degree-of-freedom robot arm 52 controls the robot arm 53 to grab the goods from the placement hook 71 and place the goods on an unattached placement hook. Simultaneously, the placement hook number corresponding to the room number is updated on the control panel 8, allowing the recipient to accurately pick up the goods.

[0054] In summary, the convenient delivery system for building exterior walls of the present invention has a small overall size, occupies only a small portion of the outdoor space, is light in overall weight, and imposes an additional load on the building that is less than the service load. It can be known without evaluation that it is suitable for most building exterior walls 1 2.

[0055] Example 2: This example provides a different vertical track. Unlike Example 1, in this example, the vertical track can be a track with an I-shaped cross-section. The left and right sides of the I-shaped track constitute vertical slide grooves. The conveying trolley is clamped on the I-shaped track, and sliding wheels are provided between the conveying trolley and the slide groove of the I-shaped track to reduce friction. At the same time, limiting is performed to prevent the conveying trolley from falling off. A pulling mechanism is provided at the position corresponding to the vertical track at the upper end of the building. The pulling mechanism includes a winch and a traction rope. The two ends of the traction rope are respectively connected to the winch and the conveying trolley. The winch is used to drive the conveying trolley to move on the vertical track.

[0056] Example 3: This example provides a different driving mechanism. Unlike Example 1, in this example, a driving rack is used to drive the driving tooth groove. Specifically, a driving rack extending vertically is provided on the side of the groove plate facing the conveying trolley. The driving gear is adapted to the driving rack, and the two are engaged for transmission. The driving motor drives the driving gear to rotate and move along the driving rack to drive the conveying trolley to move on the vertical track.

[0057] Example 4: This example provides a different conveyor trolley. Unlike Example 1, in this example, the placement position includes a conveyor plate extending in the left-right direction, and the conveying mechanism includes a conveyor belt arranged on the conveyor plate and conveying in the left-right direction. Guardrails are provided on the conveyor plate on both sides of the width direction of the conveyor belt. The placement position is an L-shaped plate corresponding to the conveyor belt. In the left-right direction, the side of the conveyor plate facing away from the conveyor trolley corresponds to the placement position. When delivering goods, the goods are first placed on the conveyor belt. When the conveyor trolley moves to the designated floor position, the conveyor plate docks with the L-shaped plate, and the conveyor belt drives the goods to move onto the L-shaped plate. The vertical section of the L-shaped plate is arranged with its back to the outer wall of the building, and its vertical section is used to block the goods from falling. At the same time, the vertical section docks with the sun and rain protection plate above, forming a barrel-shaped structure to protect the goods. At the same time, during the entire transportation process, the goods are shielded and protected to prevent them from falling.

[0058] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various modifications and variations of the present application are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
