[0059] Unless otherwise stated, the numerical ranges herein include not only the entire range within its two endpoints but also include several sub-ranges contained therein.

[0060] Figures 1 to 11 A modular six-wheeled trolley according to the present application is shown, and the modular six-wheeled trolley includes a base frame 100, a bottom plate 110, a first side panel assembly 120, and a flip lifting mechanism 130, wherein the bottom plate 110 is disposed above the base frame 100. The first side panel assembly 120 is disposed at an end of the base frame 100, and the first side panel assembly 120 is provided with a long slot 121.

[0061] Combination Figure 2 and Figure 3 As shown, the flip lifting mechanism 130 includes a flap 131 and a lifting pin 132, and the lifting pin 132 is penetrated to the base frame 100 and penetrated to the first side panel assembly 120 through the long slot 121. The first end of the flap 131 is connected to the base plate 110, and the second end of the flap 131 is pivotally connected to the first side panel assembly 120 around a first pivot axis AX1 parallel to the axis of the lifting pin 132.

[0062] Reference Figure 7 and Fig. 9 During the process of attaching the bottom panel 110 to at least a portion of the first side panel assembly 120 , the flap 131 lifts the lifting pin 132 along the vertical direction D1 .

[0063] Combination Fig.10 As shown, according to the modular six-wheeled trolley of the present application, the bottom plate 110 is attached to the first side panel assembly 120, so that the flap 131 lifts the lifting pin 132, so that the lifting pin 132 moves along the long slot 121, so that the end of the bottom frame 100 close to the first side panel assembly 120 is lifted relative to the first side panel assembly 120, so that the six-wheeled trolley can be moved horizontally and stacked together, which is conducive to saving storage space for the six-wheeled trolley. Fig.11 As shown, after the bottom plate 110 is attached to the first side panel assembly 120, the first side panel assembly 120 is rotated around the lifting pin 132 as a whole, so that the first side panel assembly 120 can be folded, which is also helpful to save the storage space of the six-wheeled trolley.

[0064] Reference Figure 1 The six-wheeled vehicle further includes a second side panel assembly 140. Along the length direction D2 of the six-wheeled vehicle, the first side panel assembly 120 and the second side panel assembly 140 are respectively arranged at both ends of the bottom frame 100. A first wheel assembly 103 is arranged in the middle of the bottom frame 100. The first side panel assembly 120 includes a second wheel assembly 122, and the second side panel assembly 140 includes a third wheel assembly 141. The first wheel assembly 103 is a fixed wheel assembly and has a brake device, and the second wheel assembly 122 and the third wheel assembly 141 are both universal wheel assemblies.

[0065] When the chassis 100 is in a horizontal position, the first wheel set 103 is lower than the second wheel set 122 and the third wheel set 141. Therefore, when the six-wheeled trolley is in normal use, the first wheel set 103 contacts the ground, and the chassis 100 has a slight tilt angle, so that the second wheel set 122 or the third wheel set 141 contacts the ground. At this time, there are two wheel sets (four wheels in total) supporting the chassis 100 and the bottom plate 110, so that the user can transport goods, etc. Since the first wheel set 103 has a brake device, the six-wheeled trolley can be braked and controlled.

[0066] Reference Figure 7 and Fig. 9 When the bottom plate 110 is attached to the first side panel assembly 120, the flap 131 lifts the lifting pin 132 and rises in the vertical direction D1, so that the end of the bottom frame 100 close to the first side panel assembly 120 moves upward relative to the second wheel set 122, so that the first wheel set 103 is off the ground. At this time, the six-wheeled trolley moves through the second wheel set 122 and the third wheel set 141, and can be laterally overlapped with another six-wheeled trolley (refer to Fig.10 ), thus saving storage space.

[0067] Reference Figure 1 and Figure 3The base frame 100 includes a main beam 101 and a vertical square tube 102. The main beam 101 extends along the length direction D2. The vertical square tube 102 is arranged at one end of the main beam 101 close to the first side panel assembly 120, and the second side panel assembly 140 is arranged at one end of the main beam 101 away from the vertical square tube 102.

[0068] Combination Figure 5 and Figure 6 As shown, the first side panel assembly 120 further includes a first side plate frame 123 and a first column 124 . The upper end of the first column 124 is connected to the first side plate frame 123 , and the lower end of the first column 124 is connected to the second wheel set 122 .

[0069] Specifically, the connection between the bottom frame 100 and the first side panel assembly 120. The vertical square tube 102 is disposed in the first column 124 and slides with the first column 124. Figure 3 The side wall of the vertical square tube 102 is provided with a plug hole 106, the lifting pin 132 is inserted into the vertical square tube 102 through the plug hole 106, and the long groove 121 is provided on the side wall of the first column 124. Figure 2 As shown, both ends of the lifting pin 132 extend to the outside of the first column 124 through the long slot 121 , so that the vertical square tube 102 is movably arranged relative to the first column 124 along the vertical direction D1.

[0070] Optionally, refer to Figure 1 and Figure 2 The flip lifting mechanism 130 further includes two split pins 133 and two washers 134. Along the width direction D3, the two washers 134 are sleeved on the lifting pin 132 and arranged on both sides of the first column 124. The split pin 133 passes through the lifting pin 132 and is arranged on the side of the washers 134 away from the first column 124, thereby limiting the lifting pin 132, realizing the detachable installation of the lifting pin 132, and making the vertical square tube 102 and the first column 124 stably connected.

[0071] Optionally, refer to Figure 1 and Figure 7According to the present embodiment, the second side panel assembly 140 further includes a second side panel frame 142 and a second column 143. The upper end of the second column 143 is connected to the second side panel frame 142, the lower end of the second column 143 is connected to the third wheel set 141, and the second column 143 is connected to the end of the main beam 101 away from the vertical square tube 102. Further, the end of the main beam 101 away from the vertical square tube 102 is provided with a mounting square tube 107, the mounting square tube 107 is fixed to the main beam 101, the lower end of the mounting square tube 107 is connected to the third wheel set 141, and the second column 143 is passed through the upper end of the mounting square tube 107 to the mounting square tube 107 and is fixed to the mounting square tube 107 by fasteners 111 such as bolts or latches, so that the second side panel frame 142 can be folded on the bottom frame 100 (such as Fig.11 shown).

[0072] In addition, as one of the alternatives, the second side panel assembly 140 can also be configured to be consistent with the structure of the first side panel assembly 120. Correspondingly, the main beam 101 is connected to the second side panel assembly 140 through another vertical square tube 102 and the flip lifting mechanism 130, so that the first side panel assembly 120 and the second side panel assembly 140 at both ends of the six-wheeled trolley can be folded (such as Fig.11 The first side panel assembly 120 is shown in the figure), thereby further saving the storage space of the six-wheeled trolley.

[0073] To fold the first side panel component 120, refer to Fig. 9 and Fig.11 The first side panel assembly 120 is rotated about the axis of the lifting pin 132 (ie Figure 2 The second pivot axis AX2 in the vertical square tube 102 can be pivoted between a vertical position and a horizontal position relative to the vertical square tube 102. When the first side panel assembly 120 is in a horizontal position, the bottom plate 110 and the first side panel frame 123 are both horizontally arranged and folded onto the bottom frame 100, and then the second side panel frame 142 is folded onto the first side panel frame 123, thereby reducing the size of the six-wheeled dolly along the vertical direction D1, further saving the storage space of the six-wheeled dolly.

[0074] Reference Figure 5 and Figure 6 The first column 124 is provided with a through hole 125, which is used to pass the upper end of the vertical square tube 102 when the first side panel assembly 120 is in a horizontal position, so that the first column 124 can be pivoted to a horizontal position to prevent the vertical square tube 102 and the first column 124 from interfering with each other. Figure 4 The vertical square tube 102 includes a lower tube 105 and an upper tube 104. The upper tube 104 and the lower tube 105 can be detachably installed, while the lower tube 105 is fixed to the main beam 101. Therefore, when the first side panel assembly 120 is as shown in FIG. Fig.11When in the folded state as shown, the upper tube 104 can be removed so that the vertical square tube 102 does not protrude from the first side frame 123 and the second side frame 142 along the vertical direction D1, making the top of the folded six-wheeled trolley flatter and easier to transport.

[0075] Optionally, refer to Figure 2 and Figure 8 The first pivot axis AX1 is located on the side of the lifting pin 132 away from the base plate 110. When the flap 131 lifts the lifting pin 132, the lifting pin 132 is located between the base plate 110 and the first pivot axis AX1, which helps prevent the lifting pin 132 from detaching from the flap 131, making the transmission of the flip lifting mechanism 130 more stable.

[0076] Further, see Figure 8 The flap 131 includes a first connecting portion 135, an abutting portion 137 and a second connecting portion 136, Figure 3 As shown, the first connection portion 135 is connected to the bottom surface of the bottom plate 110 and is fixed to the bottom plate 110 by the fastener 111. The second connection portion 136 is connected to the side of the first column 124 away from the bottom plate 110. Specifically, the second connection portion 136 is hinged to the side wall of the first column 124 away from the bottom plate 110. The abutment portion 137 is respectively connected to the first connection portion 135 and the second connection portion 136. In the process of the flap 131 lifting the lifting pin 132, the flap 131 is mainly abutted to the lifting pin 132 through the abutment portion 137. The structural design of the flap 131 is reasonable, so that the bottom plate 110 can rotate around the first pivot axis AX1 relative to the first column 124, and in the process of the bottom plate 110 being attached to the first side frame 123, the abutment portion 137 of the flap 131 lifts the lifting pin 132, so that the bottom frame 100 is lifted relative to the first column 124.

[0077] Furthermore, the abutment portion 137 and the second connection portion 136 are arranged at an angle, so that when the flap 131 lifts the lifting pin 132 to the highest position, the angle between the abutment portion 137 and the second connection portion 136 cooperates with the inner wall of the long slot 121, allowing the lifting pin 132 to pivot stably. Optionally, the abutment portion 137 and the first connection portion 135 are arranged at an angle, so that during the pivoting process of the flap 131, the first connection portion 135 can guide the lifting pin 132 to the abutment portion 137.

[0078] Optionally, refer to Figure 5 and Fig. 9The first side frame 123 is provided with a locking member 126, which is used to lock the bottom plate 110 attached to the first side frame 123, so that the bottom plate 110 and the first side frame 123 can be connected together, which is convenient for subsequent overall folding. Further, a protrusion 112 is provided at one end of the bottom plate 110 away from the flap 131, and the locking member 126 is pivotally connected to the first side frame 123. When the bottom plate 110 is attached to the first side frame 123, the locking member 126 is rotated so that the locking member 126 is sleeved on the protrusion 112 attached to the bottom plate 110, so that the bottom plate 110 and the first side frame 123 are locked together, preventing the bottom plate 110 from shaking during the process of the first side frame 123 pivoting to the horizontal position, which is convenient for folding the six-wheeled dolly.
