[0021] Example 1: Please refer to Figure 1-Figure 6 The present invention provides a technical solution: a shuttle vehicle with anti-collision protection, comprising: The vehicle body 1 has a placing plate 2 mounted thereon in a swinging manner, and the placing plate 2 is used for placing and bearing objects; it also includes: a hydraulic component 3, which is located at the front and rear sides of the placing plate 2 on the vehicle body 1, wherein a connecting block 4 is fixed to the output shaft end of the hydraulic component 3, and a push rod 5 is installed through the middle of the connecting block 4, and the ends of the push rod 5 are squeezed and positioned with the connecting pieces 6 on the front and rear outer walls of the placing plate 2; a tightening adjustment component is arranged at the penetration point between the push rod 5 and the connecting block 4, and adjusts the positioning stability strength of the push rod 5 on the connecting piece 6; a rotating shaft rod 201 is arranged at the bottom center of the placing plate 2, and the rotating shaft rod 201 and the vehicle body 1 are rotatably connected by bearings, and at the same time, spring positioners are arranged between the front and rear side edges of the bottom of the placing plate 2 and the vehicle body 1.

[0022] In the above technical solution, if Figure 1 , Figure 2 and Figure 6As shown, the auxiliary installation setting of the spring positioner is utilized so that the placement plate 2 can naturally maintain a horizontal state when it is not loaded, so that it is also convenient to push the adjustment push rod 5 to vertically position the connecting member 6 under the action of the fastening adjustment component, so as to maintain the horizontal state of the placement plate 2 when it is loaded, and realize the normal state. The object basket is placed on the placement plate 2 and the placement and stable transportation of the objects are maintained; wherein, partition members 202 are detachably installed on the front and rear side outer walls of the placement plate 2, and a through hole is provided at the connection between the placement plate 2 and the partition member 202; the setting of the partition member 202 can isolate the objects when the height of the objects placed on the placement plate 2 is relatively high, and the objects will not fall to the front and rear front parts of the vehicle body 1 and cause impact damage.

[0023] At the same time, in the technical scheme, the push rod 5 and the connecting block 4 are a through-going relative telescopic structure, wherein the connecting end of the push rod 5 and the connecting member 6 is set to an arc shape, and the connecting member 6 is provided with an inner groove for horizontally limiting the push rod 5; the fastening and adjusting assembly includes an elastic member 501 at the telescopic position through which the push rod 5 and the connecting block 4 are connected, wherein an electromagnet 502 and a permanent magnet are fixed on the outer wall of the connecting block 4 and the outer wall of the middle section of the push rod 5, respectively; wherein the electromagnet 502 and the permanent magnet are located on the inner side of the elastic member 501 as a whole, and the electromagnet 502 and the permanent magnet are coaxially distributed laterally, and the electromagnet 502 and the hydraulic assembly 3 are driven by the speed sensor and the integrated circuit on the vehicle body 1; the components of the hydraulic assembly 3, the push rod 5 and the connecting member 6 are symmetrically distributed on the front and rear sides of the placement plate 2, wherein the placement plate 2 is arranged in a "U" shape, and an active area is reserved between the outer wall of the placement plate 2 and the vehicle body 1; Use Figure 3-Figure 5In the technical solution shown, the placement plate 2 on the vehicle body 1 is adjusted to a horizontal state by components such as a hydraulic component 3, a push rod 5, a connecting piece 6, and a fastening and adjusting component. Under the monitoring of the speed sensor and the integrated circuit assembly, when the vehicle body 1 makes an emergency stop, an emergency brake, accelerates, or collides during driving, causing the driving speed of the vehicle body 1 to change rapidly in a short time, and when the change value exceeds its preset threshold, the corresponding hydraulic component 3 and the fastening and adjusting component are activated. Specifically, when the vehicle body 1 stops suddenly, the objects placed on the placement plate 2 have a tendency to fall forward due to inertia. At this time, the hydraulic component 3 in front of the vehicle body 1 contracts to drive the push rod 5 at its output end to move upward, and at the same time, the electromagnet 5 on the corresponding connecting block 4 02 generates a magnetic repulsive force on the permanent magnet on the push rod 5, so that the push rod 5 extends outward and pushes the connecting piece 6 to cause the front side of the placement plate 2 to tilt upward. At the same time, the hydraulic component 3 at the rear of the vehicle body 1 extends outward to drive the push rod 5 at its output end to move downward. At the same time, the electromagnet 502 on the corresponding connecting block 4 generates a magnetic repulsive force on the permanent magnet on the push rod 5, so that the push rod 5 extends outward and pushes the connecting piece 6 to cause the rear side of the placement plate 2 to be pressed downward; in summary, the angle of the placement plate 2 changes, so that when the vehicle body 1 is braked or the speed changes suddenly, the goods placed on the placement plate 2 have a reduced tilting tendency and movement trajectory due to its angle adjustment, thereby achieving the protection effect of the objects on the placement plate 2 to prevent them from scattering or colliding due to impact and inertia.

[0024] In addition to the above-mentioned electromagnetic control drive, the tightening and adjusting component can also be set with hydraulic drive control to drive the telescopic movement of the push rod 5; at the same time, for larger shuttle vehicles and placement plates 2, multiple components such as hydraulic components 3, push rods 5, connecting parts 6 and tightening and adjusting components can also be placed horizontally, and multiple components drive the angle deflection of the same placement plate 2 to improve overall efficiency and stability.

At the same time, the partition 12 separates the inner cavity of the vertical water tank 7. Under the action of the inner cavity and water of the vertical water tank 7, when the vehicle body 1 has a sudden change in speed such as collision or sudden braking during use, the movement of the water inside the vertical water tank 7 has the effect of releasing energy. At the same time, the separated inner cavity of the vertical water tank 7 can reduce the impact force of the water movement on the inner wall of the vertical water tank 7, thereby preventing the adverse effects caused by secondary impact.

[0026] Further, in the technical solution, a positioning cylinder 8 is fixed on the front and rear side outer walls of the vertical water tank 7, and a vertical cylinder 9 is installed in the positioning cylinder 8 in a lifting and movable manner, wherein the upper end of the vertical cylinder 9 is provided with a radar and a smoke sensor; a nozzle 10 is also installed in a through-type manner on the top of the outer wall of the vertical cylinder 9, wherein a water pump 11 is also provided at the bottom of the vertical water tank 7, and the water outlet of the water pump 11 is connected to the inside of the positioning cylinder 8 through a pipeline; wherein the lower end of the vertical cylinder 9 inside the positioning cylinder 8 is provided with a sealing sleeve, and the vertical cylinder 9 and the positioning cylinder 8 are internally through-set in a sliding connection; The relative lifting installation of the vertical cylinder 9 and the positioning cylinder 8 can adjust the installation position of the radar and smoke sensor on the top of the vertical cylinder 9. When an object that is too high is placed on the vehicle body 1, the radar and smoke sensor can be effectively used under the height adjustment function to reduce the obstruction of the object itself. At the same time, the setting of the smoke sensor, when the vehicle body 1 or the object thereon spontaneously combusts or ignites to cause smoke during use, it can start the water pump 11 through circuit application, thereby providing automatic and timely flame retardant protection.
