Description

Technical Field

[0001] This utility model relates to the field of logistics transportation technology, and in particular to a parcel locker. Background Technology

[0002] With the further development of the low-altitude economy, technologies such as drone-based rapid delivery of parcels have achieved significant progress. Currently, parcel lockers often use rack and pinion drives for door opening and closing. However, rack and pinion drives have a drawback: the locker door cannot be locked after closing, meaning it can still be opened. If power is interrupted, this further compromises the security of the parcels. Other methods use cylinders to open the doors, which, while fast, are more expensive. Therefore, reducing the cost of parcel lockers while improving cargo security is a pressing issue. Utility Model Content

[0003] This utility model provides a parcel locker to overcome the shortcomings of the prior art, solving the problems of high manufacturing cost and poor security effect, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] A parcel locker includes a locker body with a roof at the top. One side of the locker body has a hinged door for easy access and maintenance of its internal structure. An exit is located at the front of the locker, with an exit door to protect goods inside. An entrance is located on the roof, with an entrance door also hinged to it. This design facilitates drone landings and cargo delivery. The entrance and exit are connected by a passageway to allow goods to move from the entrance to the exit, preventing disruption to parcel delivery.

[0006] Furthermore, a display screen is installed on one side of the cabinet, located above the exit, to facilitate human-computer interaction.

[0007] Furthermore, the lower wall of the inlet door is fixed with a first hinge seat by screws. A first telescopic electric cylinder is hinged to the first hinge seat. The other end of the first telescopic electric cylinder is hinged to a second hinge seat. The second hinge seat is fixed to the cabinet by screws. The inlet door is opened by the first telescopic electric cylinder. The opening and closing operation is performed by the first telescopic electric cylinder. Firstly, it is easy to operate. Secondly, it has the ability to reverse lock after power failure, thereby improving the security effect.

[0008] Furthermore, the inner wall of the exit door is equipped with rollers at both the upper and lower ends, each roller containing a shaft. The inner end of the shaft is welded to the inner wall of the exit door. Guide rails are located on the lower side of the rollers at the same height. The rollers reduce the flexibility of the exit door when opening or closing. The guide rails are mounted on the cabinet via multiple mounting plates. One end of the inner frame is connected to a second telescopic electric cylinder, and the other end of the second telescopic electric cylinder is hinged to a third hinge seat. The third hinge seat is mounted on the cabinet with screws. This design prevents the exit door from opening or closing when the second telescopic electric cylinder is powered off or in a closed state.

[0009] Furthermore, the guide rails have an L-shaped or concave structure, which prevents the rollers from being exposed inside the cabinet and causing lubricating oil to drip onto the packages when they roll.

[0010] Furthermore, the inner wall of the exit door is provided with an inner frame, and an inner crossbar is welded inside the inner frame. Rollers are welded to the inner wall of the inner frame. The inner frame can improve the structural strength of the exit door.

[0011] Furthermore, in order to avoid forcibly opening the exit door from the outside and to improve the security effect after the exit door is closed, a fourth hinge seat is hinged to the movable end of the second telescopic electric cylinder. A connecting rod is passed through the fourth hinge seat, and an inner ring is fixed on the connecting rod by a pin. The inner ring is located inside the fourth hinge seat, and a locking nut is threaded onto the connecting rod. The locking nut is pressed against the fourth hinge seat.

[0012] One end of the inner frame is fitted with a base plate by screws. Side plates are bent on the upper and lower sides of the base plate. A locking rod is inserted through the side plate. The outer end of the locking rod is inserted through the guide rail. The inner end of the locking rod is connected to a movable block by threads. A support plate is welded on the movable block. An oblique hole is opened on the support plate. The oblique hole is located at one end of the movable block and extends inward at an angle. An actuating rod is inserted through the oblique hole. The outer end of the actuating rod is connected to a movable plate by threads. A protruding plate is welded on the movable plate. A connecting rod is connected to the protruding plate by threads. An end plate is bent on the base plate. A connecting rod is inserted through the end plate. A spring is sleeved on the connecting rod. The spring is located between the inner ring and the end plate.

[0013] The advantages of the above technical solution are:

[0014] This utility model firstly improves the security of each opening and closing door by using a first telescopic electric cylinder and a second telescopic electric cylinder, mainly by improving the security after a power outage, and secondly by reducing the cost of the express delivery locker.

[0020] Figure 5 A magnified view of point A is shown. Detailed Implementation

[0021] like Figures 1-5 As shown, a parcel locker includes a locker body 1, a canopy 9 at the top of the locker body 1, an opening and closing door 10 connected to one side of the locker body 1 by a hinge, an exit 12 at the front of the locker body 1, an exit opening and closing door 4 at the exit 12, an entrance on the canopy 9, an entrance opening and closing door 20 connected to the entrance by a hinge, and a connecting channel 3 connecting the entrance and the exit 12 to allow goods to move from the entrance to the exit 12. A display screen 11 is provided on one side of the locker body 1, and the display screen 11 is located above the exit 12.

[0022] The lower wall of the imported door 20 is fixed with a first hinge seat by screws. A first telescopic electric cylinder 21 is hinged to the first hinge seat. The other end of the first telescopic electric cylinder 21 is hinged to a second hinge seat. The second hinge seat is fixed to the cabinet 1 by screws.

[0023] The inner wall of the exit door 4 is equipped with rollers 45 at both the upper and lower ends, each roller 45 containing a roller shaft. The inner end of the roller shaft is welded to the inner wall of the exit door 4. Optionally, the inner wall of the exit door 4 is equipped with an inner frame 43, with an inner crossbar welded inside the inner frame 43. The roller shaft is welded to the inner wall of the inner frame 43. A guide rail 41 is located below the rollers 45 at the same height. The guide rail 41 has an L-shaped structure and is mounted on the cabinet 1 via multiple mounting plates 40. One end of the inner frame 43 is connected to a second telescopic electric cylinder 47, and the other end of the second telescopic electric cylinder 47 is hinged to a third hinge seat 46. The third hinge seat 46 is mounted on the cabinet 1 with screws.

[0024] The first telescopic electric cylinder 21 and the second telescopic electric cylinder 47 both include a cylinder body. A motor mounting base is installed at one end of the cylinder body, and a motor is installed on the motor mounting base. The motor is a servo motor. A drive gear is connected to the output shaft of the motor. The drive gear meshes with a driven gear. The driven gear is rotatably located at the end of the cylinder body. A lead screw is connected to the driven gear. A telescopic rod is threadedly connected to the lead screw. A disc is provided at the root of the telescopic rod. Multiple locking strips are provided on the inner wall of the cylinder body. The locking strips are locked at the notches of the disc. When the lead screw rotates, it will drive the telescopic rod to move telescopically under the guidance of the locking strips. With this design structure, when the lead screw does not rotate, the telescopic rod cannot be moved by thrust or other reasons, thus giving it the ability to lock in the reverse direction.

[0025] When the package is delivered, the first telescopic electric cylinder 21 will cause the inlet opening and closing door 20 to flip downward, thereby opening the inlet. Then the drone will deliver the package to the inlet, and the package will move along the connecting channel 3 to the outlet 12. Then it will wait for the instruction to retrieve the package. When it is retrieved, the second telescopic electric cylinder 47 will cause the outlet opening and closing door 4 to move, thereby opening the outlet 12, and then the package will be retrieved.

[0026] In some embodiments, to prevent damage to the second telescopic electric cylinder 47 and other components caused by external force opening the exit door 4, a fourth hinge seat 61 is hinged to the movable end of the second telescopic electric cylinder 47. A connecting rod 58 is passed through the fourth hinge seat 61, and an inner ring 59 is fixed to the connecting rod 58 by a pin. The inner ring 59 is located inside the fourth hinge seat 61, and a locking nut is threaded onto the connecting rod 58. The locking nut is pressed against the fourth hinge seat 61. One end of the inner frame 43 is fitted with a base plate 48 by screws. Side plates 49 are bent on the upper and lower sides of the base plate 48. A locking rod 50 is threaded through the side plates 49. The outer end of the locking rod 50 is threaded through the guide rail 41. The inner end of the locking rod 50 is threaded through a movable block 52. A support plate 53 is welded onto the movable block 52. An oblique hole 54 is opened on the support plate 53. The oblique hole 54 is located at one end of the movable block 52 and extends inward. An action rod 55 is threaded through the oblique hole 54. The outer end of the action rod 55 is threaded through a movable plate 56. A protruding plate 57 is welded onto the movable plate 56. A connecting rod 58 is threaded through the protruding plate 57. An end plate 51 is bent on the base plate 48. The connecting rod 58 is threaded through the end plate 51. A spring 60 is sleeved on the connecting rod 58. The spring 60 is located between the inner ring 59 and the end plate 51.

[0027] In this embodiment, when the second telescopic electric cylinder 47 drives the outlet opening and closing door 4 to close, since the resistance of the outlet opening and closing door 4 during movement is less than the resistance of the spring 60 deformation, the outlet opening and closing door 4 will close under the drive of the second telescopic electric cylinder 47. When the outlet opening and closing door 4 contacts the closing vertical rod on the cabinet 1, the outlet opening and closing door 4 will stop moving. At this time, the telescopic rod on the second telescopic electric cylinder 47 will continue to move forward. During the movement, it will push the fourth hinge seat 61 and the movable plate 56 to move forward. The movement of the movable plate 56 will drive the action rod 55 on it to move. And through the action rod 55, it will act on the inclined hole 54, thereby causing the expansion plate 53 to move outward. As the expansion plate 53 moves, the interlocking rod 50 will pass through the guide rail 41, thereby achieving the purpose of locking the position of the outlet opening and closing door 4 through the interlocking rod 50.

[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
