[0055] In the following description, numerous specific details are set forth to provide a more thorough understanding of this application. However, it will be apparent to those skilled in the art that embodiments of this application may be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described to avoid confusion with embodiments of this application.

Moreover, for example, the term “first component” does not imply the existence of a “second component”, and the term “second component” does not imply the existence of a “first component”.

[0057] In this article, terms such as "up," "down," "front," "back," "left," and "right" are used only to indicate the relative positional relationship between related parts, rather than to define the absolute position of these related parts.

[0058] In this document, terms such as “equal” and “same” are not strict mathematical and / or geometric limitations, but also include errors that are understandable to those skilled in the art and permissible in manufacturing or use.

[0059] Unless otherwise stated, the numerical ranges in this document include not only the entire range within its two endpoints, but also the subranges contained therein.

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

[0061] Combination Figure 2 and Figure 3 As shown, the tilting and lifting mechanism 130 includes a flap 131 and a lifting pin 132. The lifting pin 132 passes through the base frame 100 and through the elongated slot 121 to the first side panel assembly 120. 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 about a first pivot axis AX1 parallel to the axis of the lifting pin 132.

[0062] Reference Figure 7 and Figure 9 During the process of the base plate 110 being attached to at least a portion of the first side plate assembly 120, the flap 131 lifts the lifting pin 132 in the vertical direction D1.

[0063] Combination Figure 10 As shown, according to the modular six-wheeled trolley of this application, the base plate 110 is attached to the first side panel assembly 120, causing the flip plate 131 to lift the lifting pin 132, which moves along the long groove 121. This causes the end of the base frame 100 near the first side panel assembly 120 to be lifted relative to the first side panel assembly 120, thereby allowing the six-wheeled trolley to move laterally and stack together, saving storage space. Furthermore, in combination with... Figure 11 As shown, after the base plate 110 is attached to the first side plate assembly 120, the first side plate assembly 120 can be folded by rotating the entire assembly around the lifting pin 132, which also helps to save storage space for the six-wheeled trolley.

[0064] Reference Figure 1 The six-wheeled trolley also includes a second side panel assembly 140. Along the length direction D2 of the six-wheeled trolley, the first side panel assembly 120 and the second side panel assembly 140 are respectively arranged at both ends of the base frame 100. A first wheel set 103 is arranged in the middle of the base frame 100. The first side panel assembly 120 includes a second wheel set 122, and the second side panel assembly 140 includes a third wheel set 141. The first wheel set 103 is a fixed wheel set and has a braking device. The second wheel set 122 and the third wheel set 141 are both swivel wheel sets.

[0065] When the base frame 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, during normal use of the six-wheeled trolley, the first wheel set 103 is in contact with the ground, and the base frame 100 has a slight tilt angle, allowing either the second wheel set 122 or the third wheel set 141 to contact the ground. At this time, two wheel sets (a total of four wheels) support the base frame 100 and the base plate 110, thus facilitating the user's transportation of goods. Since the first wheel set 103 has a braking device, the six-wheeled trolley can be braked and controlled.

[0066] Reference Figure 7 and Figure 9 When the base plate 110 is attached to the first side panel assembly 120, the flip plate 131 lifts the lifting pin 132 and raises it in the vertical direction D1, causing the end of the base frame 100 near the first side panel assembly 120 to move upward relative to the second wheel set 122, thereby causing the first wheel set 103 to lift 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 stacked with another six-wheeled trolley (see reference). Figure 10 This saves 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 located at one end of the main beam 101 near the first side panel assembly 120, while the second side panel assembly 140 is located at the 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 plate assembly 120 also 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 assembly 122.

[0069] Specifically, the connection between the base frame 100 and the first side panel assembly 120 is described. The vertical square tube 102 is disposed within the first column 124 and slides in cooperation with the first column 124, as shown in the reference. Figure 3 The side wall of the vertical square tube 102 is provided with a insertion hole 106, through which the lifting pin 132 passes to the vertical square tube 102, and the long groove 121 is provided on the side wall of the first column 124. Figure 2 As shown, the two ends of the lifting pin 132 extend to the outside of the first column 124 through the long groove 121, so that the vertical square tube 102 is movably arranged relative to the first column 124 in the vertical direction D1.

[0070] Optionally, refer to Figure 1 and Figure 2 The tilting and lifting mechanism 130 also includes two cotter pins 133 and two washers 134. Along the width direction D3, the two washers 134 are fitted onto the lifting pin 132 and arranged on both sides of the first column 124. The cotter pins 133 pass through the lifting pin 132 and are arranged on the side of the washers 134 away from the first column 124, thereby limiting the lifting pin 132 and realizing the detachable installation of the lifting pin 132, so as to ensure a stable connection between the vertical square tube 102 and the first column 124.

[0071] Optionally, refer to Figure 1 and Figure 7According to this embodiment, the second side plate assembly 140 further includes a second side plate frame 142 and a second column 143. The upper end of the second column 143 is connected to the second side plate frame 142, and the lower end of the second column 143 is connected to the third wheel assembly 141. The second column 143 is also connected to the end of the main beam 101 away from the vertical square tube 102. Further, a mounting square tube 107 is provided at the end of the main beam 101 away from the vertical square tube 102. The mounting square tube 107 is fixed to the main beam 101, and the lower end of the mounting square tube 107 is connected to the third wheel assembly 141. The second column 143 extends from the upper end of the mounting square tube 107 through the mounting square tube 107 and is fixed to the mounting square tube 107 by fasteners 111 such as bolts or pins. This allows the second side plate frame 142 to be folded onto the base frame 100 (e.g., ...). Figure 11 (As shown).

[0072] Alternatively, the second side panel assembly 140 can also be configured to have the same structure as the first side panel assembly 120. Correspondingly, the main beam 101 is connected to the second side panel assembly 140 via another vertical square tube 102 and a tilting and lifting mechanism 130, thereby allowing both the first side panel assembly 120 and the second side panel assembly 140 at both ends of the six-wheeled trolley to be folded (e.g., Figure 11 (As shown in the first side panel assembly 120), further saving storage space for the six-wheeled trolley.

[0073] For folding the first side panel assembly 120, refer to Figure 9 and Figure 11 The first side panel assembly 120 is about the axis of the lifting pin 132 (i.e. Figure 2 The second pivot axis AX2 is pivotable relative to the vertical square tube 102 between a vertical and a horizontal position. When the first side panel assembly 120 is in the horizontal position, the base plate 110 and the first side panel frame 123 are both horizontally positioned and folded onto the base frame 100, and then the second side panel frame 142 is folded onto the first side panel frame 123, thereby reducing the vertical dimension D1 of the six-wheeled trolley and further saving storage space for the six-wheeled trolley.

[0074] Reference Figure 5 and Figure 6 The first column 124 is provided with a through-hole 125, which allows the upper end of the vertical square tube 102 to pass through when the first side panel assembly 120 is in a horizontal position, thereby enabling the first column 124 to pivot to a horizontal position and preventing interference between the vertical square tube 102 and the first column 124. (Refer to...) 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 are detachably installed, while the lower tube 105 is fixed to the main beam 101. Therefore, when the first side panel assembly 120 is as follows... Figure 11When the vehicle is in the folded state, the upper tube 104 can be removed so that the vertical square tube 102 will not protrude from the first side panel frame 123 and the second side panel frame 142 in the vertical direction D1, making the top of the folded six-wheeled trolley flatter and facilitating the transportation of the six-wheeled trolley.

[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. During the process of the flip plate 131 lifting the lifting pin 132, the lifting pin 132 is located between the base plate 110 and the first pivot axis AX1, which helps to prevent the lifting pin 132 from disengaging from the flip plate 131, making the transmission of the flipping lifting mechanism 130 more stable.

[0076] Furthermore, refer to Figure 8 The flap 131 includes a first connecting part 135, an abutting part 137, and a second connecting part 136, which are combined with Figure 3 As shown, the first connecting part 135 is connected to the bottom surface of the base plate 110 and fixed to the base plate 110 by fasteners 111. The second connecting part 136 is connected to the side of the first column 124 away from the base plate 110. Specifically, the second connecting part 136 is hinged to the side wall of the first column 124 away from the base plate 110. The abutting part 137 is connected to the first connecting part 135 and the second connecting part 136 respectively. During the process of the flip plate 131 lifting the lifting pin 132, the flip plate 131 mainly abuts against the lifting pin 132 through the abutting part 137. The structure of the flip plate 131 is reasonably designed so that the base plate 110 can rotate relative to the first column 124 about the first pivot axis AX1. During the process of the base plate 110 fitting against the first side plate frame 123, the abutting part 137 of the flip plate 131 lifts the lifting pin 132, thereby raising the base frame 100 relative to the first column 124.

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

[0078] Optionally, refer to Figure 5 and Figure 9The first side panel frame 123 is provided with a locking member 126, which is used to lock the base plate 110 attached to the first side panel frame 123, thereby connecting the base plate 110 and the first side panel frame 123 together for easy subsequent overall folding. Furthermore, a protrusion 112 is provided at the end of the base plate 110 away from the flip plate 131. The locking member 126 is pivotally connected to the first side panel frame 123. When the base plate 110 is attached to the first side panel frame 123, rotating the locking member 126 causes it to engage with the protrusion 112 attached to the base plate 110, thereby locking the base plate 110 and the first side panel frame 123 together. This prevents the base plate 110 from shaking during the pivoting of the first side panel frame 123 to a horizontal position, facilitating the folding of the six-wheeled trolley.
