For example, ordinary manual flatbed pallet trucks rely mainly on manual operation and can only move goods horizontally, making them unsuitable for complex terrains, such as climbing stairs. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this utility model provides a multi-functional transport vehicle with various forms and the ability to meet transport needs in various situations, thus solving the aforementioned technical problems.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional transport vehicle, including a frame, a pallet fixedly connected to one end of the frame, and a side plate fixedly connected to the lower surface of the frame. An axle is rotatably connected inside the side plate, and a mounting plate is fixedly connected to the side wall of the side plate. A reduction motor is mounted on the outer surface of the mounting plate. Angle plates are fixedly connected to both ends of the axle, and three casters are rotatably connected to the inner side of the angle plates. A push-pull rod is rotatably connected to the inner side of the frame via an axle. The frame has bent grooves running through both sides. A limit rod is slidably connected inside the bent groove. A pin is fixedly connected to both ends of the limit rod. A tension spring is hooked to the outer surface of the pin. Pins are fixedly connected to both sides of the frame. Two sleeves and four side ears are fixedly connected to the lower surface of the frame near the side. A handle is rotatably connected inside the sleeve. A guide rod is slidably connected inside the side ears. A spring is sleeved on the outer surface of the guide rod. A lever is connected to one end of the guide rod by a screw.
[0008] Preferably, one end of the tension spring is connected to pin one, and the other end of the tension spring is connected to pin two.
[0009] Preferably, the outer wall of the sleeve has an insertion hole, and the outer wall of the handle has two limiting holes. The two limiting holes are at a 90-degree angle around the axis of the sleeve, and the diameter of the two limiting holes is the same as that of the insertion hole. The end of the guide rod away from the paddle has an insertion rod, which is inserted into the insertion hole.
[0010] Preferably, a limiting ring is fixedly connected to the outer wall of the guide rod, one end of the spring abuts against the limiting ring, and the other end of the spring abuts against the side lug.
[0011] Preferably, three movable wheels are arranged in a circumferential array around the axle on the inner side of the corner plate, and two omnidirectional wheels are installed on the lower surface of the frame.
[0012] Preferably, the output shaft of the geared motor is fixedly connected to a bevel gear, and the outer circumferential surface of the shaft is fixedly connected to a bevel gear, the two bevel gears meshing with each other, and a battery pack is installed on the outer surface of the mounting plate.
[0013] Compared with the prior art, the present invention provides a multi-functional transport vehicle with the following advantages:
[0014] 1. When the limit rod is pressed down to make the push-pull rod stand upright and is fixed by the tension spring in conjunction with the limit rod, this utility model can be used as a flatbed cart on a flat ground; after folding the push-pull rod, rotating the handle and fixing it by the guide rod and spring can make one end of the frame tilt up to change its shape, meet the transportation needs of different scenarios, and improve the flexibility of use.
[0015] 2. This utility model has a mechanical power-assisted stair climbing function.

[0021] 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.
[0022] Please see Figures 1-4 A multi-functional transport vehicle includes a frame 1, a pallet 2 fixedly connected to one end of the frame 1, a side plate 3 fixedly connected to the lower surface of the frame 1, a shaft 4 rotatably connected inside the side plate 3, a mounting plate 5 fixedly connected to the side wall of the side plate 3, a reduction motor 6 mounted on the outer surface of the mounting plate 5, corner plates 7 fixedly connected to both ends of the shaft 4, three casters 8 rotatably connected to the inner side of the corner plates 7, a push-pull rod 9 rotatably connected to the inner side of the frame 1 via a shaft, and bent sliding grooves 10 extending through both sides of the frame 1. The curved slide 10 has a sliding connection to a limit rod 11. The two ends of the limit rod 11 are fixedly connected to pins 12. The outer surface of pins 12 is hooked with a tension spring 13. Pins 14 are fixedly connected to both sides of the frame 1. Two sleeves 15 and four side ears 16 are fixedly connected to the lower surface of the frame 1 near the side. A handle 17 is rotatably connected inside the sleeve 15. A guide rod 18 is slidably connected inside the side ears 16. A spring 19 is sleeved on the outer surface of the guide rod 18. One end of the guide rod 18 is connected to a paddle 20 by a screw.
[0023] Specifically, one end of the tension spring 13 is hooked to pin 12, and the other end of the tension spring 13 is hooked to pin 24.
[0024] The advantage is that by pressing down on the limiting rod 11, the pins 12 at both ends slide within the bent groove 10. At this time, the pins 12 pull the tension spring 13 and the limiting rod 11 no longer abuts against the bottom of the push-pull rod 9. When the push-pull rod 9 is erected, the tension spring 13 will drive the pins 12, which in turn will drive the limiting rod 11 to reset. At this time, the limiting rod 11 abuts against the side wall of the push-pull rod 9. Since the frame 1 is connected by multiple galvanized square tubes, one of the galvanized square tubes also abuts against the push-pull rod 9. At this time, the frame 1 can be moved by holding the push-pull rod 9. The transport vehicle in this state can be used as a flatbed truck and can move on a flat surface.
[0025] Specifically, a socket is provided on the outer wall of the sleeve 15, and two limiting holes are provided on the outer wall of the handle 17. The two limiting holes are at a 90-degree angle around the axis of the sleeve 15, and the diameter of the two limiting holes is the same as that of the socket. The end of the guide rod 18 away from the paddle 20 has a plug rod, which is inserted into the socket.
[0026] Specifically, a limiting ring 21 is fixedly connected to the outer wall of the guide rod 18, one end of the spring 19 abuts against the limiting ring 21, and the other end of the spring 19 abuts against the side ear 16.
[0027] The advantage is that when the push-pull rod 9 is folded up, the guide rod 18 can be moved by flicking the lever 20 with a finger. The guide rod 18 drives the limiting ring 21 to overcome the pressure of the spring 19, and the insertion rod at one end of the guide rod 18 is pulled out from the insertion hole on the outer wall of the sleeve 15. At this time, the handle 17 can be rotated to rotate inside the sleeve 15. After rotating 90 degrees, the two limiting holes on the outer wall of the handle 17 also rotate, so that one of the limiting holes is aligned with the insertion hole on the outer wall of the sleeve 15. At this time, under the action of the spring 19, the insertion rod of the guide rod 18 will be driven to insert into the limiting hole. In this way, the handle 17 is flipped over, making it easier to hold manually. One end of the frame 1 can be tilted up by the handle 17 (e.g., Figure 2 As shown in the figure, the transport vehicle can change shape at this time.
[0028] Specifically, three movable wheels 8 are arranged in a circumferential direction around the axle 4 on the inner side of the corner plate 7, and two omnidirectional wheels 22 are installed on the lower surface of the frame 1.
[0029] The advantage is that when switching to flatbed mode (such as...) Figure 1 As shown), at this time, two of the three movable wheels 8 connected to the inner side of the corner plate 7 will be in contact with the ground, and the caster wheel 22 will also be in contact with the ground. At this time, the entire transport vehicle can be moved by pushing and pulling the rod 9.
[0030] Specifically, the output shaft of the geared motor 6 is fixedly connected to a bevel gear, and the outer circumferential surface of the shaft 4 is fixedly connected to a bevel gear. The two bevel gears mesh with each other, and a battery pack is installed on the outer surface of the mounting plate 5.
[0031] The advantage is that when the transport vehicle is switched to such Figure 2 After reaching its current configuration, pallet 2 is used to lift goods. When climbing stairs, the reduction motor 6 is activated to drive the bevel gear to rotate, which in turn drives another bevel gear to rotate. At this time, the two bevel gears work together to drive the shaft 4 to rotate, which in turn drives the corner plate 7 to rotate. The corner plate 7 then drives the three moving wheels 8 to rotate around the shaft 4.
[0032] When the transport vehicle switches to such Figure 2 After the pallet 2 lifts the goods, the reduction motor 6 is activated when climbing the stairs. The bevel gear on the output shaft drives the bevel gear on the outer circumference of the shaft 4 to rotate, thereby causing the shaft 4 to drive the corner plate 7 to rotate. The three moving wheels 8 arranged in an array around the inner side of the corner plate 7 rotate around the shaft 4. In this way, the rotating moving wheels 8 can contact the stair steps and generate an upward driving force, enabling the transport vehicle to climb the stairs with the help of mechanical power. This greatly improves the adaptability and transport efficiency of the transport vehicle in different scenarios, making the transport of goods in the stairwell environment easier and more convenient.
[0033] In use, first, press down on the limiting rod 11, causing it to slide the pins 12 at both ends within the bent groove 10, pulling the tension spring 13 and preventing the limiting rod 11 from contacting the bottom of the push-pull rod 9. After the push-pull rod 9 is erected, the tension spring 13 will cause the pins 12 and the limiting rod 11 to return to their original positions, and the limiting rod 11 will contact the side wall of the push-pull rod 9. At this time, you can hold the push-pull rod 9 by hand to move the transport vehicle as a flatbed on a flat surface. After folding the push-pull rod 9, move the lever 20 to move the guide rod 18, pull out one end of the guide rod 18, and turn the handle 17 ninety degrees so that the limiting hole on the outer wall of the handle 17 aligns with the insertion hole on the outer wall of the sleeve 15. The spring 19 pushes the insert rod into the limiting hole, and the handle 17 flips over for easy gripping. One end of the frame 1 can be tilted up to change its shape. When the transport vehicle is in flatbed mode, two of the three moving wheels 8 on the inner side of the corner plate 7 are in contact with the ground, and the universal wheels 22 are also in contact with the ground. The transport vehicle can be moved by pushing and pulling the rod 9. After switching to the mode of the pallet 2 lifting goods, the reduction motor 6 is started when climbing stairs. Its output shaft bevel gear drives the outer bevel gear of the shaft 4 to rotate, which in turn drives the shaft 4 to rotate the corner plate 7. The three moving wheels 8 on the inner side of the corner plate 7 rotate around the shaft 4 and contact the stair steps to generate an upward driving force, realizing the climbing action.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
