[0026] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0027] like Figure 1 As shown, an embodiment of the present invention provides a floor trolley for transporting automobile floors, the floor trolley comprising:

[0028] A main frame 100, the main frame 100 includes a frame bottom plate 110 and a plurality of frame support portions 120, the plurality of frame support portions 120 pass through the top of the frame bottom plate 110 to the bottom of the frame bottom plate 110 and are connected to the frame bottom plate 110, a plurality of tire assemblies 130 are disposed at the bottom of the frame bottom plate 110, and the plurality of tire assemblies 130 are detachably connected to the bottom of the frame bottom plate 110;

[0029] A plurality of limit assemblies 200 are detachably connected to the top of the frame bottom plate 110, the limit assemblies 200 include a plurality of limit blocks 210 and a limit assembly body 220, the limit blocks 210 are movably connected to the limit assembly body 220, the plurality of limit blocks 210 are sequentially arranged from the top of the limit assembly body 220 to the bottom of the limit assembly body 220, and the plurality of limit assemblies 200 are used to support the vehicle floor.

[0030] Among them, the main frame 100 is the main structure of the floor trolley, bearing the weight of the entire floor trolley and the transported car floor. It is composed of a frame bottom plate 110 and a plurality of frame support parts 120 to form a stable and sturdy support platform. The frame bottom plate 110 and the plurality of frame support parts 120 are fixed together by welding, bolts 230 or other strong connection methods to ensure the stability and load-bearing capacity of the structure. The frame support part 120 passes from the top to the bottom of the frame bottom plate 110, increasing the strength and rigidity of the structure. The frame bottom plate 110 provides a support surface, while the frame support part 120 plays a role in strengthening and stabilizing. The two work together to ensure that the trolley can withstand various forces and vibrations during transportation. The main frame 100 can be made of stainless steel, aluminum alloy or other high-strength, corrosion-resistant materials. The frame support part 120 can be designed in different shapes and sizes to adapt to different transportation needs and working environments.

[0031] The tire assembly 130 is a key component for the floor trolley to move, which enables the floor trolley to move flexibly on different ground surfaces to meet transportation needs. The tire assembly 130 and the bottom of the frame bottom plate 110 can be fixed together by bolts 230, welding or other reliable connection methods. This connection method facilitates the replacement and maintenance of the tire.

[0032] Among them, the limiting assembly 200 and the top of the frame bottom plate 110 can be fixed together by bolt 230 connection, snap connection or other detachable connection methods. This connection method facilitates the replacement and adjustment of the limiting assembly 200. The limiting block 210 is movably connected to the limiting assembly body 220 and can move or rotate along a certain track. When the car floor is placed on the limiting block 210, the limiting block 210 can adjust the position according to the thickness of the floor to ensure that the floor is stably supported. At the same time, multiple limiting blocks 210 are arranged in sequence from the top to the bottom of the limiting assembly body 220 to form a stable support system. The purpose of the longitudinal arrangement of multiple limiting blocks 210 is to divide multiple car floors into layers, and each layer of car floors can be supported by the corresponding limiting blocks 210, and the car floors do not interfere with each other when placed, forming a preset distance, which is the distance between the limiting blocks 210. Due to the existence of the distance, the robot arm on the production line can automatically remove the car floor from the limiting block 210 by adjustment, without relying on manual unloading of the car floor.

[0033] In the embodiment of the present invention, a plurality of limit assemblies 200 are arranged on the main frame 100 of the floor trolley. When the staff places the automobile floor on the floor trolley, the automobile floor can be stacked piece by piece on the limit blocks 210. The plurality of limit blocks 210 not only support the automobile floor but also separate the automobile floor piece by piece, so that the robot on the production line can continuously and automatically take out the automobile floor on the floor trolley without manual operation, thereby significantly improving the production efficiency of the production line.

[0034] like Figure 1 As shown, in an optional embodiment of the present invention, the floor trolley also includes a rotating rod 300, one end of which is movably connected to the frame bottom plate 110, and a plurality of limit rods 310 are provided on one side of the rotating rod 300, and the plurality of limit rods 310 are used to prevent the car floor from popping out.

[0035] Among them, one end of the rotating rod 300 is connected to the frame bottom plate 110 through a movable connection (such as a hinge connection, a bearing connection, etc.). The interaction between the rotating rod 300 and the frame bottom plate 110 is mainly reflected in the rotation function. When the position of the limit rod 310 needs to be adjusted, the worker can change the relative position between the limit rod 310 and the car floor by rotating the rotating rod 300 to ensure that the limit rod 310 always fits closely to the edge of the car floor, thereby effectively fixing the car floor.

[0036] In the embodiment of the present invention, the provision of the rotating rod 300 and the limiting rod 310 ensures the stability of the vehicle floor during transportation.

[0037] like Figure 2As shown in an optional embodiment of the present invention, the spacing between the plurality of limit blocks 210 is equal.

[0038] The main function of the limit blocks 210 is to support the car floor so as to stably transport the car floor. The evenly distributed limit blocks 210 allow the workers to evenly layer the car floors when placing multiple car floors on the floor trolley. The limit blocks 210 serve as natural separators to evenly separate the floors into different upper and lower layers. The natural stratification of multiple car floors allows the robotic arms on the production line to more easily identify and grab the car floors.

[0039] like Figure 2-3 As shown, in an optional embodiment of the present invention, a plurality of the limit blocks 210 are movably connected to the limit assembly body 220 via bolts 230, and the bolts 230 pass through the limit blocks 210, so that the limit blocks 210 can make circular motion around the axis of the bolts 230.

[0040] The bolt 230 passes through the stop block 210 and is fixed to the stop assembly body 220, thereby forming a rotatable axis. The head and tail of the bolt 230 can be fixed with nuts or other fasteners to ensure a stable connection without limiting the rotation of the stop block 210.

[0041] In an optional embodiment of the present invention, the plurality of tire assemblies 130 include at least one steering wheel and at least two load-bearing wheels, wherein the steering wheel is used to control the steering of the floor trolley, and the load-bearing wheels are used to provide a stable supporting force.

[0042] Among them, the steering wheel is the key component for the floor trolley to adjust the direction. By operating the steering wheel, the staff can easily control the direction of the trolley to ensure flexible shuttle in narrow or complex production environments. The load-bearing wheel is the main component of the floor trolley to bear weight.

[0043] In the embodiment of the present invention, the tire assembly 130 is designed with at least one steering wheel and at least two load-bearing wheels, which can improve the maneuverability and stability of the floor trolley.

[0044] In an optional embodiment of the present invention, a height adjustment device is further provided on the limiting component body 220, and the height adjustment device is used to adjust the position of the limiting block 210 according to the thickness of the automobile floor.

[0045] like Figure 2-3As shown, in an optional embodiment of the present invention, the limit block 210 includes a first end 211 and a second end 212, the second end 212 is provided with a restraining member 213, the first end 211 is used to support the vehicle floor, when the vehicle floor contacts the first end 211, the first end 211 rotates downward around the bolt 230, the second end 212 drives the restraining member 213 to rotate upward around the bolt 230, and the limit block 210 stops rotating when the restraining member 213 contacts the limit assembly body 220.

[0046] Among them, the first end 211 is mainly used to support the car floor. When the car floor is placed on the trolley, it will first contact the first end 211, and by providing a stable support surface, it is ensured that the car floor will not slip or be damaged during transportation. The second end 212 is opposite to the first end 211. The second end 212 is provided with a constraint 213, and rotates together with the first end 211 around the bolt 230. The constraint 213 is used to limit the rotation range of the limit block 210, ensuring that the limit block 210 can stop after rotating to a certain position, and the constraint 213 is used to prevent the limit block 210 from over-rotating. In addition, when the robot arm of the production line takes out the car floor, the first end 211 automatically returns to its original state due to the loss of the gravity of the car floor.

[0047] Specifically, when the vehicle floor contacts the first end 211, the first end 211 rotates downward around the bolt 230 due to the weight of the floor. At the same time, the second end 212 drives the constraint 213 to rotate upward around the bolt 230. When the constraint 213 contacts the limiting assembly body 220, the limiting block 210 stops rotating due to the contact force. At this time, the vehicle floor is stably supported on the first end 211 of the limiting block 210, and the second end 212 of the limiting block 210 and the constraint 213 form a stable supporting structure with the limiting assembly body 220.

[0048] In the embodiment of the present invention, the stability of the automobile floor during transportation is ensured by the rotation of the limit block 210 and the limiting effect of the constraint member 213. The staff does not need to manually adjust or fix each piece of the automobile floor, but only needs to place it on the limit block 210 to achieve stable support, which simplifies the operation process and improves work efficiency. When the robot takes out the automobile floor, the limit block 210 returns to its original state due to the loss of the gravity of the automobile floor.

[0049] like Figure 2-3As shown, in an optional embodiment of the present invention, when the second end 212 of the limit block 210 rotates upward, the second end 212 contacts the second end 212 of the other limit blocks 210, and the limit block 210 drives the second end 212 of the other limit blocks 210 to rotate upward, so that the first end 211 of the other limit blocks 210 rotates downward.

[0050] Specifically, when the second end 212 (the portion with the restraint 213) of a stop block 210 rotates upward due to the pressure of the upper automobile floor, this action is not limited to the interior of a single stop block 210, but also affects other adjacent stop blocks 210. When the second end 212 of a stop block 210 rotates upward, it may come into contact with the second end 212 of other stop blocks 210. Once contact occurs, the rotational force or torque will be transmitted from one stop block 210 to another stop block 210, and under the transmitted force, the second end 212 of other stop blocks 210 will also begin to rotate upward. This linkage effect ensures that when a piece of automobile floor is placed, not only the stop block 210 below it will respond, but also the adjacent stop blocks 210 will adjust their positions accordingly to achieve automation.

[0051] In an optional embodiment of the present invention, the main frame 100 is made of stainless steel.

[0052] Among them, stainless steel has excellent corrosion resistance and can effectively resist corrosion under various environmental conditions, such as moisture, salt, chemicals, etc., thereby extending the service life of the main frame 100. The high strength characteristics of stainless steel can ensure that the main frame 100 remains stable when bearing multiple car floors and is not easily deformed or damaged.

[0053] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
