Description

Technical Field

[0001] The utility model relates to the technical field of logistics vehicle management, in particular to a logistics vehicle management device based on the Internet of Things. Background Technique

[0002] Logistics is the whole process of planning, implementing and managing the movement of raw materials, semi-finished products, finished products and related information from the place of production of goods to the place of consumption of goods in order to meet the needs of customers at the lowest cost through transportation, storage, distribution, etc. In reality, the transportation of goods basically relies on trucks. In order to facilitate the real-time management of transport trucks, positioning devices are installed on the trucks, and the real-time position of the goods is managed based on the Internet of Things in cooperation with the positioning devices on the trucks.

[0003] In order to improve the stability of logistics vehicle management, the prior art has made many improvements to the positioning devices of logistics vehicles. For example, the patent with the publication number CN218463569U discloses a vehicle positioning device for logistics transportation management, including a bottom plate. A vertical groove is fixedly connected to the side of the bottom plate. A push plate is fitted and movably connected to the inner wall of the vertical groove. A concave platform is fixedly connected to the lower end surface of the push plate. Circular threaded holes are opened on both sides of the bottom plate. Screws are threadedly connected to the inner walls of the circular threaded holes. Anti-loosening gaskets and nuts are sequentially threadedly connected to the outer surface of the middle part of the screws from top to bottom. A main body is fixedly connected to the upper end of the vertical groove. Ventilation holes are opened on the front and rear end surfaces of the main body. When the locator is installed and fixed inside the main body, through the ventilation holes opened on the front and rear end surfaces of the main body, the heat dissipation function of the locator inside the main body can be achieved. By pushing the dust-proof cover that is fitted and movably connected to the inner wall of the sliding channel, the dust-proof cover covers the upper end surface of the main body, thereby playing a dust-proof role and avoiding the influence of excessive dust in the use environment entering the locator and affecting the use accuracy of the locator.

[0004] The above patent has obvious beneficial effects, but there are still the following deficiencies in actual operation:

[0005] In the above comparative document, the locator is clamped between two top plates, and spring pins are provided on the back of the two top plates for shock absorption. However, the other two side walls inside the main body are in hard contact with the locator. When the logistics vehicle passes through a bumpy road surface, there is still a possibility of impact between the locator and the other two side walls inside the main body. If the size of the locator is smaller than the internal space size of the main body, the possibility of the locator being impacted will increase accordingly, so the service life of the locator will be reduced. Therefore, it is urgent in this field to improve the logistics vehicle management device based on the Internet of Things to solve the defects of the prior art. Content of the Utility Model

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0029] Please refer to Figures 1-6, An Internet of Things-based logistics vehicle management device, including a positioning unit 1 and a fixed substrate 2 provided inside the logistics vehicle. The upper surface of the fixed substrate 2 is fixedly installed with a bearing substrate 3 by screws. Above the bearing substrate 3, there is an installation substrate 4 adapted to the positioning unit 1. On the installation substrate 4, there is a clamping plate 5 that slides and fixes the positioning unit 1. On the installation substrate 4, there is a driving unit that moves and fixes the clamping plate 5. The lower surface of the installation substrate 4 is fixedly connected with several fixing plates 6. Between the fixing plates 6 and the bearing substrate 3, there is a first elastic member 7 fixedly connected. On the bearing substrate 3, there are several sliding rods 9. Symmetrical sliding plates 10 slide on the sides of the sliding rods 9. Between the two sliding plates 10, there is a second elastic member 11 sleeved on the side of the sliding rod 9. The driving unit includes a sliding groove 12 opened on the upper surface of the bearing substrate 3 and communicating with the outside. Between the two end side walls in the sliding groove 12, there is a bidirectional lead screw 13 rotatably connected. The lower side surface of the clamping plate 5 is fixedly connected with a sliding block 14 adapted to the sliding groove 12. One end of the bidirectional lead screw 13 penetrates the bearing substrate 3 and extends to the outside. When the bidirectional lead screw 13 rotates, the two sliding blocks 14 move towards or away from each other;

[0030] When it is necessary to install the positioning unit 1, the bearing substrate 3 is installed at the position of the fixed substrate 2 by screws. The positioning unit 1 is placed on the upper surface of the installation substrate 4. The positioning unit 1 is located between the two clamping plates 5. Rotate the bidirectional lead screw 13. When the bidirectional lead screw 13 rotates, it moves the two sliding blocks 14 towards each other. The sliding blocks 14 drive the clamping plate 5 to clamp and fix the positioning unit 1. When the logistics vehicle is jolted, the first elastic member 7 is compressed or stretched. At the same time, the second elastic member 11 plays a role in stretching or supporting the installation substrate 4. When the first elastic member 7 is stretched, the second elastic member 11 generates a pulling force on the installation substrate 4. When the first elastic member 7 is compressed, the second elastic member 11 plays a supporting role for the installation substrate 4, reducing the shaking of the installation substrate 4 and improving the service life of the positioning unit 1.

[0031] On the opposite surfaces of the two clamping plates 5, there are fixedly connected first fixing blocks 15. The first fixing blocks 15 are located on three sides of the positioning unit 1. A first sliding rod 16 penetrates through the first fixing blocks 15. One end of the first sliding rod 16 is fixedly connected with a pressing plate 28. Between the pressing plate 28 and the first fixing blocks 15, there is a third elastic member 17 sleeved on the side of the first sliding rod 16. The tension of the third elastic member 17 pushes the pressing plate 28. The pressing plate 28 presses against multiple sides of the positioning unit 1, improving the stability after fixing the positioning unit 1.

[0032] One end of the bidirectional lead screw 13 located outside the sliding groove 12 is fixedly connected to a rotating plate 18. A limiting unit for limiting and fixing the bidirectional lead screw 13 is provided on one side of the rotating plate 18 and the side of the mounting substrate 4. The limiting unit includes a limiting ring 19 fixedly connected to the side of the mounting substrate 4 and sleeved on the side of the bidirectional lead screw 13. A plurality of limiting grooves 20 with right-angled triangular cavities are formed on the side of the limiting ring 19. Two symmetric second fixing blocks 21 are fixedly connected to one side of the rotating plate 18. A second sliding rod 22 passes through the second fixing blocks 21. One end of the second sliding rod 22 is fixedly connected to a clamping block 23 adapted to the limiting groove 20. A fourth elastic member 24 sleeved on the side of the second sliding rod 22 is fixedly connected between the clamping block 23 and the second fixing blocks 21;

[0033] When the rotating plate 18 rotates the bidirectional lead screw 13 and the bidirectional lead screw 13 drives the sliding blocks 14 to move towards each other, the clamping block 23 slides around the side of the limiting ring 19. When the clamping plate 5 clamps and fastens the positioning unit 1, due to the clamping of the right-angled triangular clamping block 23 and the limiting groove 20, and at the same time the tension of the fourth elastic member 24 pushes the clamping block 23 to limit the rotating plate 18, thereby fixing the bidirectional lead screw 13. When it is necessary to reverse the bidirectional lead screw 13, pull the second sliding rod 22, and the clamping block 23 disengages from the limiting groove 20 to reverse the rotating plate 18.

[0034] The lower surface of the fixing plate 6 is fixedly connected to a first connecting column 25, and the upper surface of the bearing substrate 3 is fixedly connected to a second connecting column 26. The lower end of the first connecting column 25 is sleeved on the upper end of the second connecting column 26; when the bearing substrate 3 is jolted, the first connecting column 25 moves up and down outside the second connecting column 26 to prevent the first elastic member 7 from deforming.

[0035] An electromagnetic induction device 27 for sensing the positioning unit 1 is installed on the clamping plate 5. The positioning unit 1 is provided with a GPS positioning module, a processing module, an alarm module, a signal receiving module and a signal output module. The positioning unit 1 is connected to a remote monitoring end. The above-mentioned electromagnetic induction device 27 is used to sense the positioning unit 1. After the positioning unit 1 is installed, the electromagnetic induction device 27 is started to sense the positioning unit 1. The electromagnetic induction device 27 is remotely connected to the remote monitoring end through a remote control. When someone privately disassembles the positioning unit 1, the electromagnetic induction device 27 alarms through the alarm module, and at the same time the remote monitoring end alarms. Among them, the GPS positioning module is used for position positioning, the signal receiving module and the signal output module are used for signal transmission, and the processing module is used for signal processing.

[0036] Installation steps in this embodiment: The load-bearing substrate 3 is installed at the position of the fixed substrate 2 with screws. The positioning unit 1 is placed on the upper surface of the mounting substrate 4. The rotating plate 18 rotates the bidirectional lead screw 13, and the clamping plates 5 are driven by the bidirectional lead screw 13 to move towards each other to clamp the positioning unit 1. At the same time, the pressing plate 28 limits the other sides of the positioning unit 1. Meanwhile, the bidirectional lead screw 13 is limited and fixed through the cooperation of the clamping block 23 and the limiting groove 20. The electromagnetic induction device 27 is started to monitor the anti-disassembly of the positioning unit 1. Through the mutually offset forces between the first elastic member 7 and the second elastic member 11, the damage suffered by the positioning unit 1 when the mounting substrate 4 bumps on the logistics vehicle is reduced, and the service life of the positioning unit 1 is prolonged.
