Description

DESCRIPTION Smart Express Delivery Vehicle Technical Field The present invention relates to the technical field of logistics distribution, in particular to a smart express delivery vehicle.

Background At present, most of the domestic express delivery vehicles used for distribution are modified from electric tricycles plus open cargo boxes. Such express delivery carriages are not only inconvenient for the loading, unloading and distribution of items, but also pose a great threat to the safety of express delivery during transportation. Moreover, the internal structure of the traditional carriage is single, and most express items are piled up in the carriage, which is difficult for couriers to find the items in a short time.

Places such as campus and central business district have the problem of large volumes of items. However, the method adopted by most couriers is to spread all the express items on the ground in advance, which seems to solve the problem of taking too long to fetch the express items, but the hidden safety hazards cannot be ignored. In addition, it is more likely to cause confusion when people fetch their express items at the same time, thus prolonging the time of distributing the express items. Moreover, the fetching of wrong express items and the loss of express items also occur from time to time. When it rains and snows, if all the express items are put on the ground, the express items will be damaged.

Finding the express items one by one from a small compartment will increase the labor of the courier, and people to fetch their express items have to pay more waiting time.

The present invention provides a smart express delivery vehicle, which is used to solve the problems that the existing express delivery vehicle is single in structure and is time-consuming and labor-intensive in distribution of express items.

As shown in Fig. 1-3, an embodiment of the present invention provides a smart express delivery vehicle, comprising a bottom frame 1. An express item box 2 is arranged at one end of the bottom frame 1, and a horizontal moving mechanism 3 is arranged at the other end of the bottom frame 1 and provided with a longitudinal moving mechanism 4 thereon; the longitudinal moving mechanism 4 is provided with a mechanical arm 5; and the top end of the mechanical arm 5 is connected to a mechanical gripper 6 which is used for loading an express item into the express item box 2 or taking the express items out of the express item box 2.

? LU102439 In the present embodiment, in order to realize the horizontal movement of the horizontal moving mechanism 3, the horizontal moving mechanism 3 comprises a horizontal guide rail 3-1 and a horizontal slider 3-2. The horizontal guide rail 3-1 is provided with a horizontal slider 3-2. The horizontal slider 3-2 moves horizontally relative to the horizontal guide rail 3-1, and the horizontal slider 3-2 is provided with a longitudinal moving mechanism 4. In addition, the horizontal moving mechanism 3 is connected to a horizontal driving mechanism, and the horizontal driving mechanism comprises a horizontal motor 7, a horizontal ball screw 8 and a horizontal screw nut (not shown in the figure); the horizontal motor 7 is connected to the horizontal ball screw 8, the horizontal ball screw 8 is matched with and connected to the horizontal screw nut, and the horizontal screw nut is fixedly connected to the horizontal slider 3-2.

According to the smart express delivery vehicle of the present invention, the horizontal motor 7 drives the horizontal ball screw 8 to rotate. Through the cooperation of the horizontal ball screw 8 and the horizontal screw nut, the horizontal linear movement of the horizontal screw nut is realized, thereby driving the horizontal slider 3-2 to move horizontally on the horizontal guide rail 1.

In the present embodiment, in order to realize the longitudinal movement of the longitudinal moving mechanism 4, the longitudinal moving mechanism 4 comprises a longitudinal guide rail 4-1 and a longitudinal slider 4-2. The longitudinal guide rail 4-1 is provided with a longitudinal slider 4-2. The longitudinal block 4-2 moves longitudinally relative to the longitudinal guide rail 4-

1, and the longitudinal slider 4-2 is provided with a mechanical arm 5. In addition, the longitudinal moving mechanism 4 is connected to a longitudinal driving mechanism, and the longitudinal driving mechanism comprises a longitudinal motor 9, a longitudinal ball screw 10 and a longitudinal screw nut (not shown in the figure). The longitudinal motor 9 is connected to the longitudinal ball screw 10, the longitudinal ball screw 10 is matched with and connected to the longitudinal screw nut, and the longitudinal screw nut is fixedly connected to the longitudinal slider 4-2. It is understandable that the longitudinal guide rail 4-1 is arranged on the horizontal slider 3-2. Driven by the horizontal ball screw 8, the longitudinal guide rail 4-1 and the horizontal slide block 3-2 move along the horizontal guide rail 3-1 horizontally at the same time.

According to the smart express delivery vehicle of the present invention, the longitudinal motor 9 drives the longitudinal ball screw 10 to rotate. Through the cooperation of the longitudinal ball screw 10 and the longitudinal screw nut, the longitudinal linear movement of the longitudinal screw nut is realized, thereby driving the longitudinal slider 4-2 to move horizontally on the longitudinai guide rail 4-1.

The smart express delivery vehicle of the present invention converts a rotary motion into a linear motion with the ball screw, and has the characteristics of high precision, reversibility and high efficiency. The control mechanism controls both the horizontal and vertical directions, which may realize movement of two dimensions, that is, up and down and left and right.

I LU102439 In the present embodiment, in order to realize the telescopic action of the mechanical arm 5, the mechanical arm 5 comprises a mechanical main arm 5-1, a mechanical auxiliary arm 5-2 and an arm support 5-3 provided on the longitudinal moving mechanism; one end of the mechanical main arm 5-1 is hinged with the arm support 5-3, and the other end of the mechanical main arm 5-1 is hinged with the mechanical auxiliary arm 5-2; the top end of the mechanical auxiliary arm 5-2 is connected to the mechanical gripper 6. In addition, the mechanical arm 5 is connected to the mechanical arm driving mechanism, and the mechanical arm driving mechanism is a steering gear 11. It is understandable that the arm support 5-3 is provided on the longitudinal slider 4-2. Driven by the longitudinal ball screw 10, the mechanical main arm 5-1 and the mechanical auxiliary arm 5-2 on the arm support 5-3 move longitudinally along the longitudinal guide rai! 4-1 along with the longitudinal slider 4-2.

According to the smart express delivery vehicle of the present invention, the steering gear 11 is installed on joint parts of the mechanical arm 5, that is, the joint between the mechanical main arm 5-1 and the mechanical auxiliary arm 5- 2, the joint between the mechanical main arm 5-1 and the arm support 5-3, and the joint between the mechanical auxiliary arm 5-2 and the mechanical gripper 6. The joint parts of the mechanical arm 5 are also equipped with high-precision potentiometers. Under the control of the control mechanism, the steering gear 11 may drive the mechanical arm 5.

in the present embodiment, in order to realize the pick-and-place action of the mechanical gripper 6 on an express item, the mechanical gripper 6 comprises a bracket 6-1, inclined plates 6-2 and splints 6-3. One end of the bracket 6-1 is connected to the top end of the mechanical arm 5, and the other end of the bracket 6-1 is rotatably connected to two inclined plates 6-2 arranged symmetrically; and the top end of each inclined plate 6-2 is connected to the splint 6-3. In addition, the mechanical gripper 6 is connected to the mechanical gripper driving mechanism, and the mechanical gripper driving mechanism is a steering gear 12. The steering gears 12 are arranged at both ends of the bracket 6-1 and connected to the inclined plate 6-2. It may be understood that the top end of the mechanical auxiliary arm 5-2 is connected to the bracket 6-1, and the telescopic action of the mechanical arm 5 is realized by the rotation of the mechanical auxiliary arm 5-2 relative to the mechanical main arm 5-1.

According to the smart express delivery vehicle of the present invention, the steering gears 12 are installed at both ends of the bracket 6-1. Under the control of the control mechanism, the steering gear 12 drives the inclined plate 6-2 to rotate in the horizontal direction relative to the bracket 6-1, thereby changing the distance between two splints 6-3, and realizing the pick-and-place action on the express item. The inclined plate 6-2 rotates inward in the horizontal direction to reduce the distance between the two splints 6-3 and to grasp the express item.

Further, the inclined plate 6-2 is rotatably connected to the splint 6-3. Under the control of the control mechanism, the inclined plate 6-2 rotates in the horizontal direction relative to the bracket 6-1, and there is a relative rotation between the inclined plate 6-2 and the splint 6-3, so that when the two inclined plates 6-2 are rotating relative to the bracket 6-1, the two splints 6-3 are always kept relatively parallel to ensure a stable movement and stably clamp the express item.

The smart express delivery vehicle of the present invention is suitable for cities with high population density in China. The vehicle is an upgrade and transformation of the existing express delivery vehicles, and is more cost- effective in terms of environmental protection and economics. The vehicle improves the intelligence and automation of the carriage, and will thus improve the loading and unloading efficiency and reduce the distribution time, thereby reducing the work intensity of couriers.

The new generation STC15F2K60S2 is used as the main control chip in the control mechanism of the present invention. Compared with STM32, AVR and other single-chip microcomputers, the processing capacity of the STC15 may fully meet the needs of this design, and the STC15 is low in price and easy to use. Therefore, the TC15F2K60S2 is selected as the main control chip.

The whole chip is connected to scanners, card readers or fingerprint recognition equipment through multiple serial interfaces provided in the single- chip microcomputer, which may realize the replacement of corresponding modules when customer needs are different, so as to meet customer needs, thereby improving the intelligence and facilitation of this design.

Each 1/0 port of the single-chip microcomputer has only two states, that is high level or low level, may only provide mA-level current and cannot be used by the motor. Therefore, we use a relay to control the rotation of the motor. The motor of the whole design may be divided into 4 groups: X, Y, Z and step-up, and each group independently controls the forward and reverse rotation. Each group of motors uses two l/Os, with one controlling the forward rotation of the motor and the other controlling the reverse rotation of the motor. At the same time, two relays are used. The common contacts of the two relays are respectively connected to the two poles of the motor, with a normally closed pole being connected to the negative pole of a power supply, and a normally open pole being connected to the positive pole of the power supply. When the two relays are not triggered, both poles of the motor are connected to the negative pole of the power supply, and then the motor stops. When one of the relays is triggered, the two poles are a positive pole and a negative pole, and then the motor starts to rotate. The triggering of different relays will cause the motor to rotate in different directions. Under normal circumstances, the two relays will not be triggered at the same time. If they are triggered at the same time in case of an accident, the two poles of the motor are positive, the motor will not rotate or generate current to burn the motor since there is no voltage.

The embodiments above are only preferred embodiments of the present invention, and are not meant to limit the present invention. Any modification, equivalent replacement and improvement made within the spirit and principle of the present invention should fall within the protection scope of the present invention.
