Description

Technical Field

[0001] This patent belongs to the field of shopping carts, and specifically relates to a shopping cart. Background Technology

[0002] In the current technology, shopping carts are a commonly used auxiliary tool for consumers when shopping, helping them to carry large or heavy items back to their vehicles or homes. Their usage is widespread. Users have raised higher demands for the portability and storage of shopping carts, leading to the development of folding shopping carts. The folding design allows users to easily carry and store them without taking up much space, and they are also compact and space-saving when placed at home.

[0003] In addition, to ensure the stability of items placed in the shopping cart, a top cover is added to the top of the cart, which is slidably mounted on the side wall of the main body. However, a common structure involves setting a pin on the side wall and a corresponding track on the top cover, with the track fitting to the pin, allowing the top cover to slide relative to the pin and thus move horizontally; or a connector is set on the side wall, fitting to the track and extending into it, with the track sliding relative to the connector to move or rotate the top cover. However, the above-mentioned connection structures are exposed on the outside and are prone to wear and tear, and the connections between them are easily detached, making them unstable.

[0009] The above settings allow you to hide the connector in your shopping cart.

[0010] Preferably, a first opening is provided on the side wall of the groove, and a first protrusion is provided at the first end of the connector. The first protrusion is embedded in the first opening, and the two are rotatably connected.

[0011] The above configuration enables a pivotal connection between the sidewall and the connector.

[0012] Preferably, the upper cover is provided with a baffle perpendicular to the upper cover, the upper cover and the baffle form a second space, the track is arranged in the second space, the width of the second space is greater than the width of the track, the track is arranged in the middle position of the second space, a gap is formed between the track and the baffle, and the connector enters the first space through the gap.

[0013] Preferably, the track includes a first plate perpendicular to the plane of the upper cover and a second plate parallel to the plane of the upper cover. The first plate and the second plate are connected, and the distance between the first plate and its adjacent baffle is greater than the distance between the edge of the second plate and its adjacent baffle, forming a first space.

[0014] The above configuration allows the space for the connector to move to be hidden between the top cover and the second plate.

[0015] Preferably, the connector includes a first connecting portion, the first connecting portion including a connecting rod and a second protrusion disposed on the connecting rod, the extending direction of the connecting rod intersecting the extending direction of the second protrusion; the connecting rod is adapted to the gap, the second protrusion is adapted to the first space, when the upper cover slides as the connector, the connecting rod slides along the extending direction of the gap, and the second protrusion slides along the extending direction of the first space.

[0016] The above settings enable the top cover to slide while ensuring stability during the sliding process.

[0017] Preferably, a bracket with the same extension direction as the track is provided on the bottom wall of the upper cover in the second space, and protrusions protruding from the bracket are provided on both sides of the extension direction of the bracket, the protrusions being parallel to the surface of the upper cover; a stop block is provided on the first plate, the stop block being parallel to the second plate and adapted to the protrusions, the protrusions being disposed between the stop block and the second plate, and the protrusions and the stop block at least partially covering each other to lock the track relatively to the bracket.

[0018] The above settings are used to connect the track and the top cover.

[0019] Preferably, the connector further includes a platform adapted to the opening, wherein when the top cover is in the second state, the platform covers the opening to form a plane.

[0020] The above design prevents dust from entering the shopping cart through the opening and ensures a flat surface to prevent bumps and knocks.

The platform and the first connecting part are connected by a bent connecting part, and the two ends of the bent connecting part are provided with first protrusions.

[0022] Preferably, a second opening is provided at the position corresponding to the stop block on the second plate to observe the insertion position of the protrusion.

[0023] The above settings are designed to facilitate viewing the connection between the top cover and the track.

[0024] Compared with the prior art, this patent hides at least part of the connector inside the main body and the remaining part inside the top cover, that is, completely hidden inside the shopping cart with no exposed area to prevent the influence of the external environment. In addition, the second end of the connector is adapted to the first space between the top cover and the track, which indirectly improves the strength of the space it occupies during movement, making the movement more stable.

[0040] Throughout the text, the terms “top,” “bottom,” “above,” “below,” and “on top” refer to the relative positions of components of the device, such as the relative positions of the top and bottom substrates within the device. It is understood that the device is multifunctional and independent of its spatial orientation.

[0041] To facilitate understanding of the embodiments of this patent, the following will provide further explanation and description with reference to the accompanying drawings and specific embodiments. These embodiments do not constitute a limitation on the embodiments of this patent.

[0042] This embodiment provides a shopping cart, such as Figures 1-10 As shown.

[0043] The shopping cart includes a main body 1, a top cover 2, and a connector 3 that connects the main body 1 and the top cover 2.

[0044] The main body 1 includes four adjacent side walls 4 and a bottom wall located below the side walls 4. The side walls 4 and the bottom wall are connected to form a receiving space, which is used to hold items.

[0045] like Figure 1 As shown, the upper cover 2 covers the upper opening 18 of the main body 1.

[0046] like Figure 6 As shown, a baffle 5 perpendicular to the upper cover 2 is provided on the bottom side of the upper cover 2. Multiple baffles 5 are arranged around and connected in sequence, forming a second space with the upper cover 2.

[0047] The second space is provided with a bracket 6 connected to the upper cover 2. The bracket 6 is located in the middle of the second space and extends in the same direction as the second space. The bracket 6 has protrusions 7 on both sides, which are parallel to the surface of the upper cover 2.

[0048] like Figure 7 As shown, a track 8 is provided in the second space. The track 8 covers the support 6 and is connected to the support 6. The width of the second space is greater than the width of the track 8. The track 8 is located in the middle of the second space. The two sides of the track 8 form gaps with the baffles 5 adjacent to the track 8.

[0049] like Figure 8 and Figure 9 As shown, the track 8 includes a first plate 9 and a second plate 10 connected to each other. The first plate 9 is arranged perpendicular to the upper cover 2 and connected to the bottom side of the upper cover 2. The second plate 10 is arranged parallel to the upper cover 2. The distance between the first plate 9 and the adjacent baffle 5 is greater than the distance between the edge of the second plate 10 and the adjacent baffle 5. The gap formed therein forms a first space with the upper cover 2, thereby providing space and freedom for the movement of the connector 3.

[0050] A stop 11 is provided on the first plate 9, extending in a direction parallel to the second plate. The stop 11 is adapted to the protrusion 7, which is inserted between the second plate 10 and the second part 13 to lock the track 8 within the second space. Furthermore, to determine the relative position of the bracket 6 and the track 8 during assembly, a second opening 14 is provided at the position corresponding to the stop 11 on the first plate 9 to observe the insertion position of the protrusion 7.

[0051] The upper cover 2 is connected to the main body 1 via a connector 3. The connector 3 is pivotally connected to the main body 1 to drive the upper cover 2 to rotate relative to the main body 1, thereby achieving rotational opening and rotational closing. Specifically, as follows... Figure 4 As shown, the connector 3 is connected to one of the side walls 4 forming the main body 1. The corresponding side wall 4 includes a vertical portion 15 and a horizontal portion 16. The vertical portion 15 extends vertically, that is, perpendicular to the plane of the top cover 2. A groove 17 is provided on the vertical portion 15 near the interior of the shopping cart and near the top cover 2. The groove 17 is adapted to the connector 3, so that the connector 3 is at least partially placed in the groove 17. The horizontal portion 16 extends horizontally, that is, parallel to the plane of the top cover 2. An opening 18 is provided on the horizontal portion 16 corresponding to the groove 17. The opening 18 is adapted to the connector 3, so that the connector 3 can extend out of the opening 18, while providing rotational space for the pivoting of the connector 3. Through the above arrangement, the connector 3 is at least partially hidden inside the main body 1.

[0052] like Figure 3 As shown, the connector 3 includes a first connecting part 19, a bent connecting part 20, and a platform 21.

[0053] The bent connecting portion 20 is located in the middle of the connector 3, serving as the first end of the connector 3. First protrusions 22 are provided on both sides of the bent connecting portion 20. Correspondingly, first openings 23 are provided on the side walls 4 of the groove 17. The first protrusions 22 are embedded in the first openings 23. The first openings 23 and the first protrusions 22 are circular, allowing them to rotate relative to each other. This arrangement allows the upper cover 2 to rotate relative to the side walls 4 of the main body 1, enabling the upper cover 2 to be opened by rotation.

[0054] The first connecting portion 19 serves as the second end of the connector 3, entering the first space through the gap. The first connecting portion 19 includes a connecting rod 25 and a second protrusion 26 disposed on the connecting rod 25. The extending direction of the connecting rod 25 intersects the extending direction of the second protrusion 26. There are two connecting rods 25, adapted to the two gaps formed by the track 8 in the second space. The two second protrusions 26 on the two connecting rods 25 are arranged opposite each other to adapt to the first space. When the upper cover 2 slides relative to the connector 3, the connecting rod slides along the extending direction of the gap, and the second protrusion 26 slides along the extending direction of the first space. This arrangement allows the upper cover 2 to translate relative to the connector 3, that is, to move within the plane of the upper cover 2, thus realizing the translational opening of the upper cover 2.

[0055] Platform 21 extends in the same direction as the first connecting portion 19, and the two lie on two non-intersecting planes. Platform 21 and the first connecting portion 19 are connected by a bent connecting portion 20. Figure 5 and Figure 10 As shown, when the top cover 2 is rotated to its limit position of rotation that allows it to be opened, the platform 21 covers the opening 18 to form a plane.

[0056] like Figure 1 and Figure 10 As shown, the above settings enable the upper cover 2 to rotate and open and close relative to the main body 1, as well as to slide and open and close. That is, the upper cover 2 has a first state and a second state. When the upper cover 2 is in the first state, the upper cover 2 covers the main body 1 and closes the opening 18 of the receiving space. When the upper cover 2 is in the second state, the upper cover 2 opens to expose the receiving space and covers the side wall 4 connected to the connector 3.

[0057] Therefore, when the top cover 2 is in the closed state and needs to be opened, the top cover 2 can be pushed until it moves so that the connecting piece 3 abuts against the other end of the track 8 and flips downward so that it is in a position parallel to the connecting side plate; or it can be rotated until it is parallel to the connecting side and then pushed down to slide until the second state is reached; rotation and sliding can be performed simultaneously.

[0058] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this patent. It should be understood that the above description is only a specific embodiment of this patent and is not intended to limit the scope of protection of this patent. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this patent should be included within the scope of protection of this patent.
