[0021] Referring to Figures 1 - 4, A four-way shuttle car, including a vehicle body 1. The vehicle body 1 is a four-way shuttle car in the prior art, mainly used for transporting goods by logistics companies. It can greatly utilize space and transportation efficiency, and improve the transportation of goods. The double tires 2 are in the prior art. By means of an auxiliary shaft body, two tires are assembled into one tire, mainly to improve the bearing effect of the vehicle body 1 and reduce the phenomenon that the tires of the vehicle body 1 cannot bear due to the overweight of the goods and burst. The motor shaft is in the prior art, mainly used for hanging the double tires 2 and enabling them to rotate. The motor shaft is adjusted by an external control power supply. The inner groove 3 is a groove on the top surface of the vehicle body 1, mainly provided with a structure for buffering goods.

[0022] A plurality of first compression springs 4 for improving the buffering of goods are provided on the inner groove 3. The first compression springs 4 are the main buffering components. The weight of the goods is transmitted to the vehicle body 1 through the first compression springs 4, and then the vehicle body 1 transmits it to the double tires 2. The first compression springs 4 are fixedly connected to the inner groove 3 by welding. The first compression springs 4 are fixed on the inner groove 3 through ring-shaped fasteners and rivets, fixing buttons, which is mainly convenient for later maintenance. At the same time, the cost of the first compression springs 4 is low and will not directly affect logistics. A support surface 5 for contacting the goods is provided on the first compression springs 4. The support surface 5 is the contact material for the first compression springs 4 to transmit the pressure of the goods, and at the same time, it can increase the contact surface for buffering the goods.

[0023] Trigger shafts 7 for contacting the bottom of the goods are symmetrically provided on the inner groove 3. The trigger shafts 7 are components for feedback of the goods weight, and according to the size of the goods weight, they determine the reaction components on both sides of the vehicle body 1. Pressers 6 are symmetrically provided on the inner groove 3. The pressers 6 are in the prior art. The pressers 6 mainly squeeze the elastic striker inside through external pressure, so that the elastic striker collides with other components, thereby causing other components to produce lifting and supporting actions. A two-way trigger rod is provided inside the presser 6. The two-way trigger rod is the striker in the prior art. The trigger shafts 7 are slidably connected to the pressers 6 through fasteners. The fasteners can fix the trigger shafts 7 on the pressers 6. When the trigger shafts 7 are under pressure, they will transmit the force to the elastic striker.

[0024] Limit rods 9 for restricting both sides of the goods are provided on the vehicle body 1. The limit rods 9 are linearly arranged on the lifting plates 8, and they are used to intercept both sides of the goods and restrict the goods above the vehicle body 1. And both sides of the limit rods 9 are the main driving directions of the vehicle body 1. Lifting plates 8 are symmetrically provided on the vehicle body 1. The lifting plates 8 are components for automatically adjusting the height and are in the prior art. The lifting plates 8 are fixedly connected to one end of the two-way trigger rod. A trigger ejection mechanism is provided at the bottom of the lifting plates 8. Through the impact of the two-way trigger rod, the ejection mechanism is lifted upward. The limit rods 9 are fixedly connected to the lifting plates 8 through fasteners, and the fasteners can improve the stability of the limit rods 9 on the lifting plates 8.

[0025] A telescopic shaft 10 is provided on the trigger shaft 7. The telescopic shaft 10 is a prior art component that produces a telescopic action when subjected to force and transmits the force. A middle hole is provided on the vehicle body 1, and the middle hole is a square hole in the middle of the vehicle body 1. The telescopic shaft 10 is provided on the side wall of the presser 6. One end of the telescopic shaft 10 is fixed to the presser 6, and the telescopic shaft 10 penetrates through the middle hole. The telescopic shaft 10 passes through the middle hole and extends to the center of the square hole. The telescopic shaft 10 is adapted to one end of the bidirectional trigger rod and can be activated by an external pressure. A second compression spring 11 for absorbing impact is provided on the telescopic shaft 10. The second compression spring 11 mainly absorbs the excess impact force on the telescopic shaft 10. A middle member 12 is provided on the telescopic shaft 10, and the middle member 12 is a fixed component.

[0026] A support plate 14 for lifting the goods is provided on the telescopic shaft 10. The support plate 14 is used to lift the bottom of the goods and provide support for the goods inside the packaging box, reducing the phenomenon of goods damage during transportation of the packaging box. A hole is provided on the middle member 12, and the support plate 14 is fixedly connected to the hole through an elastic shaft 13. The hole is mainly used to place the elastic shaft 13. The bottom of the elastic shaft 13 is connected to the middle member 12. The telescopic shaft 10 transmits the force to the middle member 12, and the elastic shaft 13 ejects the support plate 14 by the force received, so as to abut against the bottom of the goods. The elastic shaft 13 is slidably connected to the hole through a fastener, and the fastener can provide maintenance for the elastic shaft 13.

[0027] The working principle of the present utility model is as follows: Place the goods on the vehicle body 1. The trigger shaft 7 will be pressed down according to the weight of the goods. The trigger shaft 7 transmits the downward pressure received to the presser 6. The presser 6 then transmits the force to the lifting plate 8 and the telescopic shaft 10 through the bidirectional trigger rod. The lifting plate 8 drives the limiting rod 9 to lift upward to limit both sides of the goods, reducing the tilting effect caused by the movement of the vehicle body 1. The telescopic shaft 10 transmits the force to the middle member 12, and the elastic shaft 13 inside the middle member 12 is directly ejected by the force, making the support plate 14 abut against the bottom of the goods.
