Currently, these devices are being used in major automotive production bases and logistics hubs, effectively improving the convenience and efficiency of car transfers by replacing traditional manual securing methods with automated locking operations.

[0003] Existing automatic locking devices for car transfer pallets typically use a metal pallet as the load-bearing base and are equipped with a power source, transmission mechanism, and locking components. The power source drives the transmission mechanism, which in turn drives the locking components to clamp and secure the car's tires or chassis, completing the locking action.

[0004] However, existing devices have significant drawbacks. First, the fixing effect is poor, and the device is prone to loosening during transportation due to road conditions, leading to vehicle shaking, collisions, and economic losses such as vehicle damage. Second, the device has poor storage efficiency, occupying a large amount of space when idle or transporting empty pallets, increasing transportation costs. Therefore, an automatic locking device for automobile transfer pallets is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3This utility model provides an embodiment of an automatic locking device for a car transfer pallet, comprising a pallet 5, with a housing 3 fixedly connected to the four corners of the top of the pallet 5. A snap fastener 15 is slidably connected through the housing 3, and a bevel gear 12 is fixedly connected to the outside of the snap fastener 15. Fixing plates 11 are fixedly connected to the inside of the left and right sides of the pallet 5, and a rotating rod 21 is rotatably connected inside the fixing plate 11. Bevel gears 13 are fixedly connected to both ends of the rotating rod 21, meshing with bevel gears 12. A bevel gear 14 is fixedly connected to the outside of the rotating rod 21. A motor 10 is fixedly connected to the inner wall of the right side of the pallet 5, and a bevel gear 22 is fixedly connected to the output end of the motor 10. The bevel gear 22... The bevel gear 14 meshes with the fixed plate 11, which is fixedly connected to the middle of the inside of the pallet 5. The fixed plate 11 is rotatably connected to the transmission rod 9. Both ends of the transmission rod 9 are fixedly connected to the bevel gear 8. The bevel gear 8 meshes with the bevel gear 14. After the car is loaded, the pallet 5 can be installed on the transport vehicle with the torsion lock groove by a crane. The operator uses a remote control to make the button 15 rotate automatically, so that it is firmly fixed to the transport vehicle. The motor 10 drives the bevel gear 22 to rotate, thereby driving the bevel gear 8 and the bevel gear 14 to rotate. The rotational force is transmitted through the rotating rod 21 and the transmission rod 9, driving the bevel gear 12 to rotate, thereby completing the automatic locking effect of the button 15.

[0033] Reference Figure 1 and Figure 4 A ramp 2 is provided on the right side of the tray 5. Connecting rods 1 are fixedly connected to both the front and rear sides of the ramp 2. Pin housings 7 are fixedly connected to both the front and rear sides of the tray 5. A pin 6 is slidably connected inside the pin housing 7. A spring 18 is sleeved on the outside of the pin 6. A blocking plate 19 is fixedly connected to the outside of the pin 6. When installing the ramp 2, the worker only needs to pull the pin 6 to insert the pin 6 into the groove of the connecting rod 1 to fix the ramp 2 on the tray. When disassembling the ramp 2, simply pull the pin 6 again to pull the pin 6 out of the groove of the connecting rod 1 to remove the ramp 2. The blocking block 20 is used to prevent the blocking plate 19 from detaching from the pin housing 7 under the reaction force of the spring 18, which would affect the appearance and reduce the service life of the spring 18.

[0034] Reference Figure 4 One end of the spring 18 is fixedly connected to the inner wall of the top of the pin housing 7, and the other end of the spring 18 is fixedly connected to the outer wall of the baffle plate 19. The elasticity of the spring 18 provides a continuous force to push or pull the baffle plate 19, thereby realizing the automatic reset or flexible extension and retraction of the pin 6, enhancing the stability and responsiveness of the component linkage, simplifying the mechanical operation process, and improving the reliability of the overall structure.

[0035] Reference Figure 1 and Figure 4 The bottom four corners of the pin housing 7 are fixedly connected with stop blocks 20, and the blocking plate 19 abuts against the stop blocks 20.

[0036] Reference Figure 1 and Figure 4 The baffle plate 19 is slidably connected to the inner wall of the pin housing 7. The blocks 20 at the four corners of the bottom of the pin housing 7 abut against the baffle plate 19, which can effectively limit the displacement range of the baffle plate 19, prevent it from moving out of the preset trajectory due to the force of the spring 18 or external force, ensure the stability of the pin 6 structure operation, and avoid component misalignment affecting the overall function.

[0037] Reference Figure 1 The pin 6 is inserted into the inside of the connecting rod 1, forming a stable connection structure, which can enhance the linkage and integrity between the two and ensure the effective transmission of force.

[0038] Reference Figure 1 and Figure 2 A second disc 17 is fixedly connected to the middle of the outer side of the button 15, and a first disc 16 is fixedly connected to the middle of the outer side of the button 15. The first disc 16 abuts against the top of the second bevel gear 12. The abutting between the first disc 16 and the second bevel gear 12 can ensure stable transmission. The two discs can enhance the structural strength of the button 15 and improve the stability and durability of the locking component.

[0039] Reference Figure 1 Two support plates 4 are fixedly connected to the front and rear sides of the top of the pallet 5. The support plates 4 flatten the groove between the two outer shells 3, so that the car can be parked smoothly on the pallet 5.

[0040] Working principle: After the truck is loaded, the pallet 5 is installed onto the transport vehicle with the torsion lock groove by a crane. The remote control controls the automatic rotation of the toggle 15, and the motor 10 drives the five bevel gears 22 to rotate, which in turn drives the first bevel gear 8 and the fourth bevel gear 14 to rotate. The rotational force is transmitted through the rotating rod 21 and the transmission rod 9, driving the second bevel gear 12 to rotate, thus realizing the automatic locking of the toggle 15 with the transport vehicle. When installing the inclined plate 2, pull the pin 6 to make it engage with the groove of the connecting rod 1 to fix the inclined plate 2; when disassembling, pull the pin 6 again to disengage it from the groove to remove the inclined plate 2. The bottom stop 20 of the pin housing 7 abuts against the blocking plate 19, which can prevent the blocking plate 19 from disengaging from the pin housing 7 when the spring 18 is subjected to the reaction force, thus avoiding affecting the appearance and shortening the life of the spring 18. At the same time, the spring 18 connects the pin housing 7 and the blocking plate 19 to ensure that the pin 6 can be flexibly reset.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
