Description

Technical Field

[0001] This application belongs to the field of cargo transportation technology, and in particular relates to a foldable supermarket shopping cart. Background Technology

[0002] Traditional shopping cart designs typically employ a rigid frame and wheels, resulting in a fixed size that prevents folding. When not in use, consumers often need to find a designated storage space for their carts, creating additional inconvenience. This is especially problematic in space-constrained environments like homes or offices.

[0003] Furthermore, for situations where carrying a shopping cart is necessary, such as shopping in another city or country, the fixed size of traditional shopping carts makes them very difficult and impractical to carry. Therefore, the non-foldable nature of traditional shopping carts limits their convenience and flexibility of use.

[0004] To address this issue, some shopping cart designs have adopted a foldable design. However, these designs typically focus only on the foldability of the wheels, neglecting the folding of the cart body. Such designs still suffer from inconvenience because the cart body still occupies a significant amount of space.

[0005] Therefore, how to reduce the space occupied by the shopping cart when it is not in use is a problem that needs to be solved by those skilled in the art. Utility Model Content

Detailed Implementation

[0040] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0041] It should be noted that when a component is referred to as being "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0042] It should be understood that the terms "length", "width", "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0043] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0044] As described in the background section, traditional shopping cart designs typically employ a rigid frame and wheels, resulting in a fixed size and inability to fold. When not in use, consumers often need to find a fixed storage space for their shopping carts, causing additional inconvenience. This is especially problematic in space-constrained environments such as homes or offices.

[0045] Furthermore, for situations requiring the transport of shopping carts, such as shopping in another city or country, the fixed size of traditional shopping carts makes them very difficult and impractical to carry. Therefore, the non-foldable nature of traditional shopping carts limits their convenience and flexibility. To address this issue, some shopping cart designs have adopted foldable designs. However, these designs typically focus only on the foldability of the wheels, neglecting the folding of the cart body. Such designs still suffer from inconvenience because the cart body still occupies a significant amount of space.

[0046] Based on this, this application improves the relevant shopping cart structure.

[0047] Please refer to the following: Figures 1 to 2 and Figure 5 , Figure 1 This embodiment shows a schematic diagram of the shopping cart in its normal state. Figure 2 This diagram illustrates the shopping cart in its folded state as provided in this embodiment. Figure 5 A partial structural schematic diagram of the shopping cart provided in this embodiment is shown. In the foldable shopping cart of this embodiment, the cart body 100 includes a front panel 140, a left side panel 110, a right side panel 130, a rear panel 120, and a bottom panel 150.

[0048] The front panel 140, left side panel 110, right side panel 130, rear panel 120, and bottom panel 150 enclose a cavity with one open end and a vehicle body 100. In one easily understood embodiment, the vehicle body 100 is a hexahedral structure with one end.

[0049] Compared to existing shopping carts, the shopping cart in this application also has the following structure:

[0050] The front panel 140 is rotatably connected to one side of the left panel 110 and the right panel 130 on both sides respectively; the other side of the left panel 110 and the right panel 130 is rotatably connected to both sides of the rear panel 120; one end of the bottom panel 150 is rotatably connected to the lower end of the rear panel 120, and the other end is supported by the lower end of the front panel 140, the lower end of the left panel 110, or the lower end of the right panel 130; the other end of the bottom panel 150 is a movable end.

[0051] Furthermore, the left panel 110 has a first folded state folded along the first crease line 111, and the right panel 130 has a second folded state folded along the second crease line 131; that is, the left panel 110 and the right panel 130 themselves can be folded up; before folding, the left panel 110 and the right panel 130 are perpendicular to the front panel 140 and the rear panel 120, and the front panel 140 and the rear panel 120 are separated from each other to form a storage space; after the left panel 110 and the right panel 130 themselves are folded up, they become parallel to the front panel 140 and the rear panel 120, and the front panel 140 and the rear panel 120 can be close together; greatly reducing the volume of the entire shopping cart.

[0052] When folding, first rotate the movable end of the bottom panel 150 so that the bottom panel 150 is parallel to the rear panel 120, then push the front panel 140 and the rear panel 120 together. The left panel 110 is folded along the first crease line 111, and the right panel 130 is folded along the second crease line 131, so that the front panel 140 and the rear panel 120 are together. When the shopping cart needs to be stored, rotate the bottom panel 150 upwards to be parallel to the rear panel 120, and the shopping cart can be folded directly. When the goods need to be transported, put down the bottom panel 150, which serves to support the cart body.

[0053] See Figure 1 , Figure 3 and Figure 4 In this embodiment, the left side panel 110 includes a front left side panel 1112 and a rear left side panel 1111 that are rotatably connected to each other. The other side of the front left side panel 1112 is rotatably connected to the front panel 140; the other side of the rear left side panel 1111 is rotatably connected to the rear panel 120; a first crease line 111 is formed between the front left side panel 1112 and the rear left side panel 1111; when folded, the front left side panel 1112 and the rear left side panel 1111 rotate relative to each other, from an unfolded state on the same plane to a state forming an angle along the first crease 111, and then rotate until their surfaces are in contact with each other. When the front left side panel 1112 and the rear left side panel 1111 form a certain angle, the entire left side panel 110 is concave into the shopping cart body.

[0054] Similarly, the right side panel 130 includes a front right side panel 1312 and a rear right side panel 1311 that are rotatably connected to each other. The other side of the front right side panel 1312 is rotatably connected to the front panel 140; the other side of the rear right side panel 1311 is rotatably connected to the rear panel 120; a second crease line 131 is formed between the front right side panel 1312 and the rear right side panel 1311; when folded, the front right side panel 1312 and the rear right side panel 1311 rotate relative to each other, from an unfolded state on the same plane to a state where they form an angle 131 along the second crease, and then rotate until their surfaces are in contact with each other. When the front right side panel 1312 and the rear right side panel 1311 form a certain angle, the entire right side panel 130 is concave towards the shopping cart.

[0055] See Figure 3 and Figure 4 The front left side panel 1112 has a rotating shaft 1114 at its edge, and both ends of the rotating shaft are connected to the front left side panel 1112 via connectors 1115, creating a gap between the rotating shaft 1114 and the edge of the front left side panel 1112. The rear left side panel 1111 has a mounting buckle 1113 at its edge, with one end connected to the rear left side panel 1111 and the other end extending outward away from the rear left side panel 1111 to form a semi-cylindrical groove. The other end of the mounting buckle 1113 extends into the gap between the rotating shaft 1114 and the edge of the front left side panel 1112. The rotating shaft 1114 is inserted into the semi-cylindrical mounting groove of the mounting buckle 1113, forming a structure in which the front left panel 1112 rotates relative to the rear left panel 1111. When the front left panel 1112 and the rear left panel 1111 rotate relative to each other, the rotating shaft 1114 rotates within the semi-cylindrical mounting groove of the mounting buckle 1113. Since the other end of the mounting buckle 1113 extends into the gap between the rotating shaft 1114 and the edge of the front left panel 1112, the rotating shaft 1114 can be effectively restricted from sliding out of the mounting groove. Preferably, the opening of the semi-cylindrical mounting groove is less than 90 degrees.

[0056] In this embodiment, there can be multiple rotating shafts 1114 and mounting buckles 1113, distributed along the first crease line 111. The structure of the right side panel 130 can be the same as that of the left side panel 110.

[0057] In this embodiment, the first crease line 111 and the second crease line 131 are co-located in a first plane, which is parallel to the rear panel 120 and / or the front panel 140; the bottom panel 150 is configured such that when the left side panel 110 is in a first folded state and the rear panel 120 is in a second folded state, the bottom panel 150 is at least disengaged from the contact state with the rear panel 120 and / or the front panel 140.

[0058] Please refer to the embodiments described in this application. Figure 1 In this embodiment, the first crease line 111 is located at the midline of the left panel 110 along the length of the first direction; and / or, the second crease line 131 is located at the midline of the right panel 130 along the length of the first direction; wherein, the first direction is the position on the left panel 110 from the rear panel 120 to the front panel 140. That is to say, the width of the left panel 110 and the right panel 130 after folding can be reduced.

[0059] In this embodiment, a handle 400 is also provided on the rear panel 120 to facilitate pushing the shopping cart.

[0060] In this embodiment, the rotation structure between the front panel 140, the left side panel 110, the rear side panel 120, and the right side panel 130 should not be limited to the structure shown in the accompanying drawings. Other rotation structures commonly found in the art should also fall within the protection scope of this application.

[0061] Please refer to the embodiments described in this application. Figure 1 And see Figure 6 , Figure 6 An exploded view of a portion of the structure of the shopping cart provided in this embodiment is shown. The cart body 100 of this embodiment also includes a first support rod 200, which is detachably disposed on the side of the left panel 110 opposite to the bottom panel 150. One end of the first support rod 200 extends to the rear panel 120 and is detachably connected to the rear panel 120, and the other end extends to the front panel 140 and is detachably connected to the front panel 140. And / or, the cart body 100 also includes a second support rod 300, which is detachably disposed on the side of the right panel 130 opposite to the bottom panel 150. One end of the second support rod 300 extends to the rear panel 120 and is detachably connected to the rear panel 120, and the other end extends to the front panel 140 and is detachably connected to the front panel 140.

[0062] In other words, since the vehicle body 100 is a foldable structure, in the unfolded state, relying solely on the bottom panel 150 to support the front panel 140 and rear panel 120 may result in structural instability of the vehicle body 100. The first support rod 200 and / or the second support rod 300 can support the structure of the left panel 110 and / or the right panel 130 when the vehicle body 100 is in the unfolded state, and can also enhance the connection stability between the left panel 110 / right panel 130 and the rear panel 120 and the front panel 140.

[0063] In particular, due to the design of the first crease line 111 and the second crease line 131, if the front left side panel 1112 and the rear left side panel 1111 are not fixedly connected by a support rod, the stability of the entire vehicle body 100 will be greatly reduced. Preferably, in addition to connecting the left side panel 1112 and the rear left side panel 1111, the length of the first support rod 200 should also be sufficient to connect the rear panel 120 and the front panel 140. That is to say, the first support rod 200 connects the rear panel 120, the front panel 140, and the left side panel 110 at the same time. The structure of the first support rod 300 can be the same as that of the first support rod 200, which will not be described in detail here.

[0064] Preferably, when the overall height of the vehicle body 100 is not less than 350mm, the design of the first support rod 200 and the second support rod 300 is indispensable.

[0065] In some embodiments of this application, please refer to Figure 6 and Figure 7 In this embodiment, the first support rod 200 is provided with a first groove 240, and the left side panel 110, at least a portion of the rear panel 120, and at least a portion of the front panel 140 are adapted to be inserted into the first groove 240; and / or, the second support rod 300 is provided with a second groove, and the right side panel 130, at least a portion of the rear panel 120, and at least a portion of the front panel 140 are adapted to be inserted into the second groove. This is beneficial to improving the connection stability between the first support rod 200 and the left side panel 110, rear panel 120, and front panel 140, and also beneficial to improving the connection stability between the second support rod 300 and the right side panel 130, rear panel 120, and front panel 140.

[0066] In some embodiments of this application, Figure 7A schematic diagram of the structure of the first support rod 200 provided in this embodiment is shown. The first support rod 200 of this embodiment is provided with a first fastening part 220, and the left side panel 110 is provided with a first fastening groove 112. After the left side panel 110 is adapted to be inserted into the first groove 240, the first fastening groove 112 and the first fastening part 220 are properly fastened, further fixing the first support rod 200 and the left side panel 110. And / or, the second support rod 300 is provided with a second fastening part, and the right side panel 130 is provided with a second fastening groove, the second fastening groove and the second fastening part being adapted to fix the second support rod 300 and the right side panel 130. This is beneficial to improving the connection stability between the first support rod 200 and the left side panel 110, and also beneficial to improving the connection stability between the second support rod 300 and the right side panel 130.

[0067] In actual use, the first support rod 200 and the second support rod 300 play an important role in stabilizing the cart body when unfolded. When folding the shopping cart, the first support rod 200 and the second support rod 300 need to be removed, and then the bottom panel 150 needs to be rotated to be parallel with the rear panel 120. Finally, the front panel 140 and the rear panel 120 need to be pushed together to complete the folding of the cart body 100. However, this also means that when folding, the first support rod 200 and the second support rod 300 are independent of the cart body. During the folding process and when storing the shopping cart after folding, the first support rod 200 and the second support rod 300 are easy to lose and become unusable next time.

[0068] To further address the above issues, please refer to [link / reference needed]. Figure 1 , Figure 2 and see Figure 6 , Figure 6 A schematic diagram of the shopping cart structure provided in this embodiment is shown. At least two first insertion portions 230 are spaced apart on the first support rod 200, and at least two first insertion holes 1201 are correspondingly spaced apart on the rear panel 120. The first insertion portions 230 and second insertion holes 1201 are inserted and adapted to each other. And / or, at least two second insertion portions are spaced apart on the second support rod 300, and at least two second insertion holes are correspondingly spaced apart on the rear panel 120. The second insertion portions and second insertion holes are inserted and adapted to each other. After folding the cart body 100, the first support rod 200 and the second support rod 300 can still be folded and stored together with the cart body 100, effectively preventing the first support rod 200 and the second support rod 300 from being lost.

[0069] It should be noted that the first insertion part 230 and the first buckle groove 112 are located on different sides of the first support rod 200, so that the first insertion part 230 does not affect the normal connection between the first support rod 200 and the left side panel 110.

[0070] In some embodiments of this application, the structure of the first plug-in portion 230 is the same as that of the second plug-in portion, and the structure of the first plug-in hole 1201 is the same as that of the second plug-in hole.

[0071] See Figure 9 To further prevent the first support rod 200 and the second support rod 300 from being lost, the first support rod 200 in this embodiment is provided with a first fixing rope 210. One end of the first fixing rope 210 is connected to the first support rod 200, and the other end is connected to the rear panel 120. The first fixing rope 210 has a certain length, which is sufficient to ensure that the first support rod 200 will not be broken when it moves from the position connected to the left side panel 110 to the position connected to the rear panel 120. Similarly, the second support rod 300 can also be provided with a second fixing rope 310, and the second fixing rope 310 can have the same length as the first fixing rope 210.

[0072] The first fixing rope 210 ensures that during the folding process, after the first support rod 200 is removed from the left side panel 110 and is not yet connected to the rear panel 120, it remains connected to the vehicle body, preventing the first support rod 200 from being lost during the folding process due to carelessly discarding it.

[0073] In this embodiment, a support portion 1410 extends from the lower end of the front panel 140, the left side panel 110, or the right side panel 130 in a direction parallel to the bottom panel 150. The support portion 1410 is used to support the bottom panel 150 and its movable end. When using the shopping cart, the bottom panel 150 itself is used to open the front panel 140 and the rear panel 120. At the same time, the support portion 1410 is used to provide an upward force to the bottom panel 150. When items are placed in the shopping cart, the support portion 1410 restricts the bottom panel 150 from rotating downward, thereby forming a stable accommodating space.

[0074] In a preferred embodiment, the support part 1410 is provided with a positioning hole 1412, and the bottom panel 150 is provided with a protruding positioning block 1511 on the side near the support part; when the support part 1410 supports the bottom panel 150, the positioning block 1511 is inserted into the positioning hole 1412; this further prevents the bottom panel 150 from shifting in other directions during use; the overall shopping cart is more stable and reliable during use.
