Description

Technical Field

[0001] This utility model belongs to the field of shopping cart technology, specifically relating to a foldable power-assisted shopping cart. Background Technology

[0002] With the fast pace of modern life and the arrival of an aging society, shopping carts have been widely used in family shopping, supermarket shopping, and the transportation of everyday items.

[0003] However, existing shopping carts still have many shortcomings in actual use. Traditional shopping carts are mostly fixed frames with a lack of flexible folding design, resulting in a large size that is inconvenient for home storage or carrying when going out.

[0004] Most shopping carts have limitations in terms of load-bearing capacity and stability. When carrying heavy items or with the help of users, they are prone to shaking or even tipping over, posing a safety hazard.

[0005] Existing shopping carts generally lack seating designs suitable for people with mobility impairments, making it difficult for users to sit down comfortably during long shopping trips or breaks. They also lack safety support structures such as handrails and safety belts, resulting in a poor user experience.

[0006] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Utility Model Content

Detailed Implementation

[0024] like Figures 1 to 5 As shown, a power-assisted shopping cart includes a cart body 1. A front frame 10 and a rear frame 20 are respectively provided on both sides of the cart body 1. The upper ends of the front frame 10 and the rear frame 20 are foldably connected. A lower crossbar 30 is movably connected between the front frame 10 and the rear frame 20, providing lateral support and limiting function when the cart body is unfolded. A seat cushion bracket 40 is movably installed at the upper end of the cart body 1. An upper pull rod 41 is movably connected to the middle side of the seat cushion bracket 40. A rear pull rod 21 is movably connected to the lower side of the rear frame 20. The upper pull rod 41, the lower crossbar 30, and the rear pull rod 21 are hinged together by fasteners, forming a stable triangular mechanical structure. When in use, the front frame 10 and rear frame 20 are in the unfolded state, with the lower crossbar 30 providing support and limiting, ensuring the overall stability of the cart. The seat support 40 opens to form a seat, allowing users with mobility issues to sit and rest temporarily. The upper pull rod 41 and rear pull rod 21 work together to further enhance the cart's structural stability, preventing deformation when carrying a user. When folding for storage, the user simply folds the upper pull rod 41, rear pull rod 21, and lower crossbar 30 in sequence, while simultaneously folding the front frame 10 and rear frame 20 inwards. This results in a significantly reduced cart size, making it easy for users to carry and store at home.

[0025] In practice, the upper part of the front frame 10 is equipped with a frame connecting seat 11, and the top of the rear frame 20 is provided with a connecting through part 22. The connecting through part 22 is connected to the frame connecting seat 11 and is hinged to the frame connecting seat 11 by fasteners passing through the connecting through part 22. In use, the front frame 10 and the rear frame 20 maintain a movable connection through the frame connecting seat 11 and the connecting through part 22, so that the shopping cart body 1 can form a stable support frame when unfolded. When folding is required, the connecting through part 22 rotates within the frame connecting seat 11, thereby driving the front frame 10 and the rear frame 20 to close inward, achieving overall folding.

[0026] In practical implementation, the front frame 10 has support connecting frames 12 on both sides, and the front sides of the seat cushion support 40 have symmetrical support through parts 42. The support through parts 42 correspond to the support connecting frames 12 and are hinged to the support connecting frames 12 by fasteners passing through the support through parts 42. In use, the seat cushion support 40 can rotate around the hinge point between the support through parts 41 and the support connecting frames 12. When a seat is needed for the user, the seat cushion support 40 can be flipped and unfolded to form a stable seat structure. When not in use, the seat cushion support 40 can be folded and attached to the shopping cart body 1 to save space and facilitate the folding and storage of the shopping cart.

[0027] In specific implementation, the lower side of the front frame 10 is provided with a first crossbar connection position 13, and the upper side of the rear frame 20 is provided with a second crossbar connection position 23. One end of the lower crossbar 30 is hinged to the first crossbar connection position 13 by fasteners, and the other end of the lower crossbar 30 is hinged to the second crossbar connection position 14 by fasteners, so that the lower crossbar 30 plays the role of lateral support and limitation when the vehicle body is unfolded.

[0028] In practical implementation, the seat cushion bracket 40 has a first pull rod connection position 43 on its side center. The upper end of the upper pull rod 41 is hinged to the first pull rod connection position 43 by fasteners. The lower side of the rear frame 20 has a second pull rod connection position 24. The lower end of the rear pull rod 21 is hinged to the second pull rod connection position 24 by fasteners. The lower crossbar 30 has a pull rod through hole 31 in its middle. The lower end of the upper pull rod 41 is correspondingly located on one side of the pull rod through hole 31. The upper end of the rear pull rod 21 is correspondingly located on the other side of the pull rod through hole 31, and is hinged to the upper pull rod 41, the pull rod through hole 31 and the rear pull rod 21 by fasteners passing through them. Through this structure, a stable triangular support structure is formed between the upper pull rod 41, the rear pull rod 21 and the lower crossbar 30. When in use, this structure can effectively improve the stress stability and load-bearing capacity of the overall frame. At the same time, it can be quickly folded up when folded, ensuring a balance between strength and portability of the walking aid.

[0029] In practical implementation, a seat cushion 44 is installed on the seat support 40, and handles 14 are symmetrically arranged on both sides of the top of the front frame 10. Each handle 14 has a handrail 15 at its front end. When in use, the user can hold the handrail 15 for support, thereby obtaining good stability when standing, walking or resting. When the user needs to rest, he / she can sit on the seat cushion 44 and use the handles 14 and handrail 15 to assist in getting up or sitting down, thus improving the convenience and comfort of using the walking aid.

[0030] In practice, the front frame 10 is equipped with swivel front wheels 16 on both sides of its bottom, and the rear frame 20 is equipped with movable rear wheels 25 on both sides of its bottom. When in use, the swivel front wheels 16 can rotate 360 ​​degrees, allowing the shopping cart to turn flexibly during movement and making it easy to operate in narrow spaces. The movable rear wheels 25 provide stable support and bear the main load during pushing, thereby ensuring the overall balance and safety of the shopping cart.

[0031] In practice, a front guard strap 17 is installed on the upper front part of the front frame 10. The front guard strap 17 is positioned above the seat cushion 44. When in use, the front guard strap 17 can effectively prevent the user from leaning forward when sitting on the seat cushion 44, thereby improving the safety and stability of the ride. At the same time, the front guard strap 17, together with the armrest 15 and the seat cushion 44, forms a support and protection area, providing reliable riding and support for users with mobility impairments.

[0032] In summary, the design of this utility model helps the shopping cart to have good structural stability and load-bearing capacity. The front frame 10, rear frame 20, lower crossbar 30, upper pull rod 41, and rear pull rod 21 form a multi-point hinged support, making the cart body stable and reliable during use. The seat support 40, together with the seat 44, armrest 15, and front guard strap 17, provides a comfortable seat and safety support for users with mobility impairments, making it easy to sit down or get up. The hinged folding structure allows the shopping cart to be quickly folded up, and the folded size is small, making it easy to carry and store.
