[0054] 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.

[0055] In this document, ordinal numbers such as “first” and “second” used in this application are merely identifiers and do not have any other meaning, such as a specific order. 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”.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] Figures 1 to 9 A standardized transport vehicle according to this application is shown. The standardized transport vehicle includes a chassis 100 and a first side panel assembly 120. The chassis 100 includes a main beam 101 and a vertical rod 102. The vertical rod 102 is disposed at the end of the main beam 101 and includes a fixing rod 105 and a disassembly rod 104. The fixing rod 105 is connected to the main beam 101, and the disassembly rod 104 is detachably connected to the fixing rod 105.

[0060] The first side panel assembly 120 is movably connected to the vertical rod 102 between the extended position and the retracted position. The first side panel assembly 120 is provided with a through-hole 125 for passing through the vertical rod 102 when in the retracted position.

[0061] The fixing rod 105 does not protrude from the first side plate assembly 120 in the retracted position along the vertical direction D1.

[0062] According to the standardized transport vehicle of this application, when the first side panel assembly 120 is in the retracted position, the vertical rod 102 passes through the opening 125 of the first side panel assembly 120 and the disassembly rod 104 of the vertical rod 102 is removed. At this time, the fixing rod 105 does not protrude from the first side panel assembly 120 in the vertical direction D1, thus facilitating the stacking of standardized transport vehicles, improving space utilization, and benefiting the storage and transportation of transport vehicles.

[0063] The standardized transport vehicle also includes a tilting and lifting mechanism 130 and a base plate 110. The base plate 110, the underframe 100, and the first side panel assembly 120 can switch between various configurations through the tilting and lifting mechanism 130. For example... Figure 1To standardize the working state of the transport vehicle, the first side panel assembly 120 is in the unfolded position and extends along the vertical direction D1. For example... Figure 2 The base plate 110 is flipped toward the first side plate assembly 120 by the flipping and lifting mechanism 130 until it is as shown. Figure 3 As shown, the base plate 110 is attached to the first side panel assembly 120, at which point the standardized transport vehicle can be moved laterally and stacked. For example... Figure 4 The base plate 110 is attached to the first side panel assembly 120 and flipped to the retracted position along with the first side panel assembly 120, thereby enabling the stacking of standardized transport vehicles.

[0064] Reference Figure 1 and Figure 2 The standardized transport vehicle also includes a second side panel assembly 140. The first side panel assembly 120 and the second side panel assembly 140 are respectively arranged at both ends of the base frame 100 along the length direction D2. The first side panel assembly 120 includes a first wheel set 122. A second wheel set 103 is arranged in the middle of the base frame 100. The second side panel assembly 140 includes a third wheel set 141. The second wheel set 103 is a fixed wheel set and has a braking device. Both the second wheel set 103 and the third wheel set 141 are omnidirectional wheel sets.

[0065] When the base frame 100 is in a horizontal position (e.g.) Figure 1 As shown, the second wheel set 103 is lower than the first wheel set 122 and the third wheel set 141. Therefore, when the standardized transport vehicle is in normal use, the second wheel set 103 is in contact with the ground, and the underframe 100 will have a slight tilt angle, allowing either the first 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 underframe 100 and the base plate 110, thus facilitating the transport of goods, etc. Since the second wheel set 103 has a braking device, the standardized transport vehicle can be braked and controlled.

[0066] When the base plate 110 flips and attaches to the first side plate assembly 120, the vertical rod 102 is lifted relative to the first side plate assembly 120 under the action of the flipping and lifting mechanism 130, thereby causing the second wheel set 103 to leave the ground. At this time, the standardized transport vehicle moves through the first wheel set 122 and the third wheel set 141 and can be stacked laterally with another standardized transport vehicle, thereby saving storage space.

[0067] To be more specific, consider the structure of standardized transport vehicles. (Refer to...) Figure 2The first side panel assembly 120 also includes a first side plate frame 123 and a first column 124. Along the vertical direction D1, 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 first wheel assembly 122. The first column 124 is connected to a vertical rod 102, and a through-hole 125 is provided on the first column 124. When the first side panel assembly 120 is in the retracted position, the vertical rod 102 passes through the through-hole 125 to the first column 124, thus providing a limiting distance between the first side panel assembly 120 and the base frame 100, making the first side panel assembly 120 more stable in the retracted position.

[0068] Combination Figure 5 and Figure 3 As shown, the base frame 100 also includes a mounting square tube 155, which is disposed at the end of the main beam 101 away from the first side panel assembly 120 and fixed to the main beam 101. The lower end of the mounting square tube 155 is connected to the third wheel assembly 141. The second side panel assembly 140 also includes a second side plate frame 142 and a second column 143. Along the vertical direction D1, 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 passes through the upper end of the mounting square tube 155 into the mounting square tube 155 and is fixed to the mounting square tube 155 by fasteners 111 (not shown in the figure) such as pins or bolts, so that when the standardized transport vehicle is in a folded state (see reference...), Figure 4 The second column 143 can be removed from the mounting square tube 155, so that the second column 143 and the second side plate frame 142 are horizontally stacked on top of the first side plate assembly 120, which reduces the height dimension of the standardized transport vehicle in the vertical direction D1 and facilitates transportation.

[0069] Reference Figure 5 and Figure 6 The fixing rod 105 is in the shape of a square tube, and the side wall of the fixing rod 105 is fixedly connected to one end of the main beam 101 near the first side piece assembly 120.

[0070] Reference Figure 7 The disassembly rod 104 includes a protrusion 106 and a through part 107. The through part 107 is connected to the protrusion 106 and passes through the fixing rod 105, thereby making the connection between the disassembly rod 104 and the fixing rod 105 more stable.

[0071] In detail, the protrusion 106 is in the shape of a square tube, and the through-hole 107 includes two side panels 150, a connecting plate 154, and a bottom panel 151. Both the side panels 150 and the connecting plate 154 extend in the vertical direction D1. The two side panels 150 are spaced apart along the width direction D3 of the standardized transport vehicle and are respectively connected to the two vertical sides of the connecting plate 154. The bottom panel 151 is disposed at the lower end of the side panels 150 and the connecting plate 154, and is fixedly connected to both the side panels 150 and the connecting plate 154. Furthermore, the upper ends of the connecting plate 154 and the side panels 150 are connected to the bottom surface of the protrusion 106. When the disassembly rod 104 and the fixing rod 105 are fixed, the through part 107 passes through the fixing rod 105 until the bottom panel 151 contacts the inner bottom surface of the fixing rod 105, and the bottom surface of the protrusion 106 abuts against the upper end of the fixing rod 105. This ensures that the disassembly rod 104 and the fixing rod 105 have good integrity after being connected together, which is beneficial for the assembly of the vertical rod 102 and the first column 124. In addition, the vertical rod 102 has a larger dimension along the vertical direction D1, which can better cooperate with the first column 124 (especially in vertical relative movement).

[0072] Optionally, the projection of the protrusion 106 along the vertical direction D1 coincides with the projection of the fixing rod 105 along the vertical direction D1, so that the side wall of the vertical rod 102 formed after the disassembly rod 104 and the fixing rod 105 are smooth, which further enhances the integrity of the disassembly rod 104 and the fixing rod 105 and facilitates the assembly of the vertical rod 102 and the first column 124.

[0073] Optionally, a nut 109 is provided inside the through-hole 107, and the through-hole 107 is provided with a first mounting hole (not shown in the figure). The fixing rod 105 is provided with a second mounting hole 108. The vertical rod 102 also includes a fastener 111, which passes through the second mounting hole 108 and the first mounting hole and is threadedly engaged with the nut 109, thereby fixing the disassembly rod 104 and the fixing rod 105 together. This achieves the detachable installation of the disassembly rod 104 and the fixing rod 105, making it easy to remove the disassembly rod 104 after the standardized transport vehicle is folded.

[0074] Specifically, such as Figure 6 and Figure 7As shown, a first mounting hole and nut 109 are provided on the bottom panel 151, and a second mounting hole 108 is provided on the bottom surface of the fixing rod 105. When the through-hole 107 of the disassembly rod 104 is inserted into the fixing rod 105, the bottom panel 151 of the through-hole 107 contacts the inner bottom surface of the fixing rod 105, and the first mounting hole and the second mounting hole 108 are aligned, thus facilitating the installation of fasteners 111 from the bottom of the fixing rod 105, connecting the disassembly rod 104 and the fixing rod 105 together. Furthermore, when the standardized transport vehicle is folded, there are no structural obstructions on the bottom surface of the fixing rod 105, making it easy for workers to remove the fasteners 111 from the bottom surface of the fixing rod 105, thereby removing the disassembly rod 104.

[0075] Specifically, the structure of the tilting and lifting mechanism 130 and the base plate 110.

[0076] like Figure 8 and Figure 9 As shown, the first column 124 is provided with a long slot 121, and the flipping and lifting mechanism 130 includes a flap 131 and a lifting pin 132. The lifting pin 132 passes through the fixed rod 105 and through the long slot 121 to the first column 124, so that the vertical rod 102 is movable relative to the first column 124 in the vertical direction D1 and can be pivotally set around the second pivot axis AX2 (i.e. the axis of the lifting pin 132).

[0077] Specifically, refer to Figure 6 The side wall of the fixing rod 105 is provided with a first insertion hole 152, as shown in the reference. Figure 7 Correspondingly, the side wall of the side panel 150 is provided with a second insertion hole 153. When the disassembly rod 104 is fixed with the fixing rod 105, the first insertion hole 152 and the second insertion hole 153 are aligned for the lifting pin 132 to pass through, so that the connection between the lifting pin 132 and the vertical rod 102 is more stable.

[0078] Optionally, combined Figure 8 As shown, 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 rod 102 and the first column 124.

[0079] Combination Figure 3 As shown, the first end of the flap 131 is connected to the base plate 110 via fastener 111, refer to Figure 8 and Figure 9The second end of the flap 131 is pivotally connected to the first column 124 about a first pivot axis AX1 parallel to the axis of the lifting pin 132. During the process of the base plate 110 being attached to at least a portion of the first side plate frame 123, the flap 131 lifts the lifting pin 132 in the vertical direction D1, causing the lifting pin 132 to move along the long groove 121, thereby causing the vertical rod 102 to rise in the vertical direction D1 relative to the first column 124, thereby causing the end of the base frame 100 near the first side plate assembly 120 to rise, allowing the second wheel set 103 to be lifted off the ground, and thus enabling the standardized transport vehicle to move laterally by means of the first wheel set 122 and the third wheel set 141, facilitating the stacking of standardized transport vehicles.

[0080] Optionally, refer to Figure 9 The flap 131 can be a plate-like structure with two bends, so that when the base plate 110 moves the flap 131 upward, the lifting pin 132 is guided to the inclined surface in the middle of the flap 131. When the lifting pin 132 is at the top of the long groove 121, the lifting pin 132 is located at the clamping position of the bend of the flap 131 and the top of the long groove 121, which facilitates the stable pivoting of the first side plate frame 123 and the base plate 110 around the second pivot axis AX2.

[0081] Optionally, the first side panel frame 123 is provided with a locking member 126, which is used to lock the bottom plate 110 attached to the first side panel frame 123, thereby connecting the bottom plate 110 and the first side panel frame 123 together, which facilitates subsequent overall folding.

[0082] 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 plate frame 123. When the base plate 110 is attached to the first side plate frame 123, the locking member 126 is rotated so that the locking member 126 is fitted onto the protrusion 112 attached to the base plate 110, thereby locking the base plate 110 and the first side plate frame 123 together, preventing the base plate 110 from shaking during the process of the first side plate frame 123 pivoting to the horizontal position, and facilitating the folding of the standardized transport vehicle.
