Description

Technical Field

[0001] This utility model relates to the field of transport vehicle technology, specifically to an auxiliary support structure for an electric transport vehicle. Background Technology

[0002] In numerous fields such as logistics and warehousing management, electric pallet trucks have become indispensable equipment in cargo handling due to their high efficiency, flexibility, and environmental friendliness. They can quickly and accurately transfer goods from one location to another, greatly improving operational efficiency and reducing labor costs. However, in practical applications, electric pallet trucks face many complex working environments and operational challenges. Especially under complex road conditions or heavy-duty conditions, their stability issues are becoming increasingly prominent, becoming a key factor restricting their further development and widespread application.

[0003] In complex road conditions, warehouse floors may have potholes, slopes, or obstacles, while factory workshop floors may have narrow spaces and poor passage due to equipment placement and stacked goods. When electric pallet trucks travel in these conditions or when the center of gravity of goods is unevenly distributed during loading and unloading, the stability of the truck will be severely affected. In such cases, the truck is prone to swaying and tilting. If the tilt angle is too large, the pallet truck is highly likely to overturn. Overturning not only damages goods and causes economic losses, but also poses a serious threat to the personal safety of operators. According to relevant statistics, accidents caused by pallet truck overturning account for a significant proportion of accidents in the logistics and warehousing industry, causing huge losses and injuries to companies and employees. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary support structure for electric pallet trucks to solve the problem mentioned in the background art that electric pallet trucks are prone to tipping over in complex road conditions or during loading and unloading of goods.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary support structure for an electric pallet truck, comprising a pallet truck body, a handrail installed on one side of the pallet truck body, an adjustable handle provided on the handrail, support components symmetrically installed on the side of the pallet truck body near the handrail, the support components being used to prevent the pallet truck body from tipping over, and a locking component provided inside the pallet truck body, the locking component being used to install the support components.

[0006] Preferably, a mounting base is installed on the side of the transport vehicle body near the handrail, a control panel is installed on one side of the mounting base, a battery is installed on the side of the mounting base away from the handrail, and a handle is fixedly installed on the side of the battery.

[0007] Preferably, the support assembly includes a plurality of mounting columns installed on both sides of the transport vehicle body, a support arm rotatably mounted between two mounting columns on the same side, a caster wheel installed at one end of the support arm, a sliding groove provided on one side of the support arm, hydraulic cylinders symmetrically mounted on both sides of the transport vehicle body, a sliding block installed at the output end of the hydraulic cylinder, and the sliding block slidably mounted in the sliding groove.

[0008] Preferably, a support groove is provided on one side of the mounting column, a slider is slidably installed in the support groove, a connecting shaft is fixedly installed between two adjacent sliders, and one end of the support arm away from the universal wheel is rotatably installed on the connecting shaft.

[0009] Preferably, a pressure spring is fixedly installed on one side of the slider, and the other end of the pressure spring is fixedly installed on one side of the support groove.

[0010] Preferably, a slot is provided on one side of the mounting base, and the slot engages with the hydraulic cylinder.

[0011] Preferably, the locking assembly includes a connecting plate mounted on one side of the mounting post, the connecting plate having a plurality of locking holes, the mounting base having a mounting cavity, the mounting cavity having a control box, telescopic arms symmetrically mounted on both sides of the control box, a locking block fixedly mounted on one side of the telescopic arm, the locking block having a locking groove, a plurality of locking teeth fixedly mounted on one side of the locking groove, the locking teeth being adapted to the locking holes.

[0012] Preferably, the width of the mounting cavity is equal to the length of the long side of the locking block.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The auxiliary support structure of the electric pallet truck is equipped with support components. Through the symmetrically arranged support arms and casters, a stable support surface can be quickly formed when the vehicle body is tilted, effectively preventing the pallet truck from tipping over and significantly improving operational safety; the hydraulic cylinder-driven automatic deployment mechanism, combined with the buffering effect of the pressure spring, ensures both rapid response of the support components and reduces impact when in contact with the ground, protecting the structural integrity of the equipment; the cooperation between the sliding block and the sliding groove, as well as the guiding effect of the connecting shaft, makes the movement trajectory of the support arm precisely controllable, ensuring optimal support angle; the preload of the pressure spring... The design provides cushioning during support and assists in resetting, enabling smooth deployment and retraction of the support components. The engaging structure of the slots and hydraulic cylinders ensures the components are firmly fixed when not in operation, preventing accidental deployment during travel. The entire support system is intelligently controlled via a control panel, automatically activating when a tilt risk is detected and automatically resetting after tilt correction, ensuring both operational safety and maintaining the maneuverability of the transport vehicle. The coordinated work of all components significantly enhances the vehicle's anti-tipping ability without affecting normal handling operations, making it particularly suitable for use in complex road conditions or heavy-duty conditions, demonstrating high practical value and promising market prospects.

[0014] Equipped with a locking component, the telescopic arm controlled by the control box works in conjunction with the locking block with locking teeth to achieve one-click quick installation and removal of the support component, significantly improving loading and unloading efficiency. The meshing design of the locking teeth and locking holes forms a reliable mechanical interlock, which, together with the locking groove, clamps and fixes the connecting plate, ensuring that the support component will not loosen or shift during vehicle operation. The equal width design of the mounting cavity and the long side of the locking block ensures a smooth and precise push-out process, avoiding alignment deviations during installation. The drive mechanism built into the control box maintains a constant locking force, ensuring that the locking teeth and locking holes are always in optimal meshing, guaranteeing connection strength while avoiding wear caused by excessive tightness. The overall structure adopts a symmetrical layout, with simultaneous locking on both sides to ensure balanced force distribution and effectively disperse the working load of the support component. This locking component is simple and reliable to operate, requiring no additional tools for installation and removal. It not only meets the safety requirements for rapid deployment of the support component but also facilitates daily maintenance, significantly improving the practicality and service life of the equipment.

[0024] Example 1

[0025] Please see Figures 1-5This utility model provides an embodiment of an auxiliary support structure for an electric pallet truck, comprising a pallet truck body 1, a handrail 2 installed on one side of the pallet truck body 1, an adjustable handle 3 provided on the handrail 2, and support components symmetrically installed on the side of the pallet truck body 1 near the handrail 2 to prevent the pallet truck body 1 from tipping over. A locking component is provided inside the pallet truck body 1 for installing the support components. A mounting base 4 is installed on the side of the pallet truck body 1 near the handrail 2, a control panel 25 is installed on one side of the mounting base 4, a battery 6 is installed on the side of the mounting base 4 away from the handrail 2, and a handle 5 is fixedly installed on one side of the battery 6.

[0026] When using this electric pallet truck, the operator presses the adjustment handle 3 to release the internal limiting device, allowing the handrail 2 to slide smoothly within the guide groove. The handrail 2 can then be pulled out to the desired position as needed. When the adjustment handle 3 is released, the limiting device automatically resets, and the handrail 2 is securely locked in its current position. This ensures that the operator can freely adjust the length of the handrail 2 according to their height and operating habits, achieving optimal ergonomic control and improving work comfort and safety. During the operation of the pallet truck body 1, the tilt sensor built into the mounting base 4 monitors the tilt angle of the pallet truck body 1 in real time. If the tilt angle of the pallet truck body 1 exceeds the set safety threshold due to uneven ground, load shift, or other factors, the control panel 25 will immediately issue a control command to activate the support components installed on both sides of the pallet truck body 1. The support components quickly unfold under the action of the electric drive unit until they are in contact with the ground. The surface contact forms a stable and reliable support surface, effectively distributing the load on the tilted side of the transport vehicle body 1, enhancing the lateral support capacity of the entire vehicle, thereby preventing rollover accidents caused by center of gravity shift, and ensuring the safety of equipment and operators. In addition, the locking component is installed inside the transport vehicle body 1, adopting a quick locking and releasing structure, which facilitates the installation and disassembly of the support component. When the support component wears out due to long-term use, or when the support component is not needed according to the actual operation scenario, the operator can quickly disassemble or replace the support component by manipulating the locking component, greatly improving the maintenance convenience and usage flexibility of the equipment. The battery 6 cooperates with the handle 5 through the fixing structure on the mounting base 4, ensuring that the battery 6 has good convenience and safety when used, maintained or replaced. The overall structural layout is reasonable and the functions are efficiently coordinated, effectively improving the safety, stability and user operation experience of the electric transport vehicle.

[0027] Please see Figure 2 and Figure 3The support assembly includes several mounting posts 9 installed on both sides of the transport vehicle body 1. A support arm 11 is rotatably mounted between two mounting posts 9 on the same side. One end of the support arm 11 is equipped with a caster wheel 16. A sliding groove 15 is opened on one side of the support arm 11. Hydraulic cylinders 17 are symmetrically mounted on both sides of the transport vehicle body 1. A sliding block 18 is installed at the output end of the hydraulic cylinder 17 and is slidably mounted in the sliding groove 15. A support groove 10 is opened on one side of the mounting post 9. A slider 13 is slidably mounted in the support groove 10. A connecting shaft 14 is fixedly mounted between two adjacent sliders 13. The end of the support arm 11 away from the caster wheel 16 is rotatably mounted on the connecting shaft 14. A pressure spring 12 is fixedly mounted on one side of the slider 13 and the other end of the pressure spring 12 is fixedly mounted on one side of the support groove 10. A slot 7 is opened on one side of the mounting base 4 and engages with the hydraulic cylinder 17.

[0028] When the transport vehicle body 1 is at risk of tilting during operation, the tilt sensor built into the mounting base 4 will monitor the tilt angle of the vehicle body in real time. Once the tilt angle exceeds the preset safety threshold, the control panel 25 will immediately activate the support assembly. At this time, the hydraulic cylinders 17 symmetrically installed on both sides of the transport vehicle body 1 will work synchronously, and their output ends will extend and push the sliding block 18 to slide in the sliding groove 15 of the support arm 11. This action will cause the support arm 11 to rotate downwards and unfold around the connecting shaft 14. During the rotation of the support arm 11, the slider 13 will slide in the support groove 10 of the mounting column 9 through the connecting shaft 14, while the compression spring 12 will accumulate elastic potential energy. As the support arm 11 continues to rotate, the universal wheels 16 installed at its ends will gradually contact the ground to form auxiliary support. During this process, the elastic force of the pressure spring 12 can effectively buffer the impact and maintain the stability of the support. When the sensor in the mounting seat 4 detects that the tilt angle of the vehicle body has been corrected to a safe range, the hydraulic cylinder 17 stops moving. At this time, the position of the sliding block 18 in the sliding groove 15 is fixed, so that the support arm 11 is kept in the optimal support position at the tilt angle. The engaging structure between the slot 7 and the hydraulic cylinder 17 ensures that the support assembly is firmly fixed in the non-working state, preventing accidental unfolding. When the transport vehicle body 1 is completely restored to balance, the output end of the hydraulic cylinder 17 retracts, driving the sliding block 18 to move in the opposite direction. The support arm 11 is retracted upward under the reset action of the pressure spring 12, the caster wheel 16 is lifted off the ground, and the entire support assembly returns to the initial storage state, ensuring that the normal driving of the transport vehicle is not affected.

[0029] Please see Figures 4-5The locking assembly includes a connecting plate 26 installed on one side of the mounting post 9, with several locking holes 24 on the connecting plate 26. The mounting base 4 has a mounting cavity 8, and a control box 19 is installed in the mounting cavity 8. Telescopic arms 20 are symmetrically installed on both sides of the control box 19. A locking block 21 is fixedly installed on one side of the telescopic arm 20. A locking groove 23 is opened in the locking block 21. Several locking teeth 22 are fixedly installed on one side of the locking groove 23. The locking teeth 22 are adapted to the locking holes 24. The width of the mounting cavity 8 is equal to the length of the long side of the locking block 21.

[0030] Work steps

[0031] When the support assembly needs to be installed, the operator issues a command through the control panel 25. Upon receiving the signal, the control box 19 drives the symmetrically mounted telescopic arms 20 on both sides to extend outward, causing the locking block 21 to be smoothly pushed out of the mounting cavity 8. At this time, the design that the width of the mounting cavity 8 is equal to the length of the long side of the locking block 21 ensures that the pushing process is stable and does not deviate. The operator accurately places the connecting plate 26 into the locking groove 23 of the locking block 21 and adjusts the position so that the locking hole 24 on the connecting plate 26 is completely aligned with the locking tooth 22 in the locking block 21. Then, the telescopic arms 20 are retracted and reset through the control panel 25. During the reset process, the locking tooth 22 is precisely inserted into the locking hole 24 to form a mechanical interlock. Simultaneously, under the pulling force of the telescopic arm 20, the locking block 21 firmly clamps the connecting plate 26 into the locking groove 23. After locking, the control box 19 maintains a constant pressure on the telescopic arm 20 to ensure that the locking teeth 22 and the locking hole 24 are always tightly engaged, preventing the support assembly from loosening during the operation of the transport vehicle. When it is necessary to disassemble the support assembly, the telescopic arm 20 is extended again through the control panel 25, so that the locking teeth 22 exit from the locking hole 24, and the connecting plate 26 can be removed from the locking groove 23, completing the quick disassembly of the support assembly. The entire locking process is carried out by one-button operation, which not only ensures the firmness of the support assembly installation, but also greatly simplifies the installation and disassembly process.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
