Description

Technical Field

[0001] This utility model relates to the field of lightweight food cart technology, and more specifically, to a convenient flip-over food cart. Background Technology

[0002] Light-duty food carts are typically equipped with a flip-top structure for storing or displaying goods. However, traditional flip-top structures face many problems in daily use: traditional ordinary hinges lack a power assist mechanism, and the flipping relies entirely on manual support. Especially after adding additional modules such as insulation layers, the weight increases, typically by 5-15 kg, making operation strenuous and easily tiring for users; most food cart flip-tops cannot be fixed at a fixed angle after opening, and are prone to accidental closure in wind or bumps, posing safety hazards such as pinching fingers or damaging items inside the cart; electric power assist solutions are costly and dependent on power sources, while mechanical counterweight solutions are bulky, neither of which is suitable for light-duty mobile food carts. Utility Model Content

[0003] The purpose of this utility model is to provide a lightweight food cart that can be easily flipped over, so as to solve the problems of difficult operation, difficulty in fixing the hovering angle, and low safety of current lightweight food carts.

[0004] To address the aforementioned problems, this utility model first provides a lightweight food cart that can be easily flipped, comprising: a food cart body and a foldable and flip-up platform on it, wherein the flip-up platform and the food cart body are hinged at the flip-up point on the upper surface; at least one of the adjacent opposite sides of the flip-up platform and the food cart body is equipped with a power-assisted drive assembly; the power-assisted drive assembly includes a nitrogen spring and piston rods and mounting ends located at their respective ends, wherein the outer end of the piston rod is connected to the side plate of the flip-up platform, and the mounting end is connected to the side plate of the food cart body, wherein the piston rod extends and retracts when the flip-up platform is flipped.

[0005] This design, with a power-assisted drive assembly installed between the tilting platform and the main body of the food cart, utilizes a nitrogen spring to generate a constant reaction force when the sealed nitrogen inside is pressurized. This counteracts the weight of the tilting platform during tilting, allowing only a small external force to drive the tilting platform to open and close. This greatly reduces the burden of traditional manual operation. Furthermore, the combination of the nitrogen spring and piston rod provides a balanced assist torque, enabling effortless opening and closing as well as hovering at any angle. The hovering support is stable during operation, ensuring good safety and solving the problem of items being damaged or people being injured due to external forces during the tilting and opening process.

[0006] Furthermore, the tilting platform can tilt at an angle of 0-180° relative to the food cart body, and can hover at any angle within the tilting angle range.

[0007] Furthermore, the mounting height of the mounting end is lower than the mounting height of the piston rod. When the tilting platform is tilted to 180° relative to the food cart body, a triangular structure is formed between the power-assisted drive assembly, the tilting platform, and the food cart body.

[0008] Furthermore, a first mounting base is provided on the side plate of the tilting table, and a connector is provided at the outer end of the piston rod, the connector being detachably connected to the first mounting base.

[0009] Furthermore, the side plate of the tilting platform is provided with a plurality of first mounting bases, and the connector can be detachably connected to any of the first mounting bases.

[0010] Furthermore, a second mounting base is provided on the side panel of the food cart body, and the mounting end is detachably connected to the second mounting base.

[0011] Furthermore, the tilting platform is hinged to the food cart body via a hinge made of stainless steel. Attached Figure Description

[0021] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0022] To address the problems of cumbersome flip-top operation, difficulty in maintaining a fixed hovering angle, and low safety in current lightweight food carts, this embodiment provides a lightweight food cart that can be easily flipped over, such as... Figure 1 As shown, the food cart body has a flip-up platform that can be folded and flipped relative to each other, and the two are hinged at the flip-up point on the upper surface. Figure 3 As shown in the schematic diagram of a relative 180° rotation, the light-duty dining cart has a power-assisted drive component installed on at least one of its two opposite sides, preferably on both sides.

[0023] Specifically, such as Figure 4 As shown, the power steering assembly includes a nitrogen spring and piston rods and mounting ends located at its two ends, wherein, combined with Figure 2 As shown, the outer end of the piston rod is connected to the side plate of the tilting platform, and the mounting end is connected to the side plate of the food cart body. When the tilting platform tilts, it drives the piston rod to extend and retract. The nitrogen spring is sealed with nitrogen, which generates a constant reaction force when compressed, offsetting the weight of the tilting platform during tilting. This allows only a small external force to drive the tilting platform to open and close, greatly reducing the burden of traditional manual operation, making operation easier and opening and closing more convenient.

[0024] In this embodiment, the tilting angle of the tilting platform relative to the food cart body is 0-180° to prevent the lid from opening excessively. If it exceeds 190°, it may cause structural damage or user error. Figure 3 The nitrogen spring and piston rod combination provides a balanced assist torque for the maximum flipping angle and allows for hovering at any angle within the flipping range without additional support. This allows users to easily adjust the opening and closing angle to suit different usage scenarios. The specific principle will not be elaborated further, as those skilled in the art will understand. This design ensures stable hovering support and good safety during operation, solving the problem of damage to items or injury to personnel due to external forces during the flipping and opening process.

[0025] Preferably, the mounting height of the mounting end is lower than the mounting height of the piston rod, such as... Figure 3 As shown, when the tilting platform is tilted to 180° relative to the food cart body, a stable triangular structure is formed between the power-assisted drive component, the tilting platform, and the food cart body.

[0026] like Figure 1As shown, a first mounting base is provided on the front side plate of the tilting platform, and a connector is provided at the outer end of the piston rod. The connector is detachably connected to the first mounting base. Similarly, a second mounting base is provided on the front side plate of the food cart body, and the mounting end is detachably connected to the second mounting base. The detachable connection methods include threaded connection and magnetic connection. In this embodiment, the connector is a bolt.

[0027] Preferably, multiple first mounting bases can be provided on the side plate of the tilting table, and the connector can be detachably connected to any of the first mounting bases. This allows the installation position of the piston rod to be adjusted according to the weight and size of the tilting table, i.e., the pointing of the nitrogen spring can be adjusted. This facilitates matching different weights without the need to replace the power assist drive components, enhances adaptability, and makes it easy to be compatible with tilting tables of different sizes and materials. It is suitable for various light-duty food carts, such as snack carts, coffee carts, and beverage carts.

[0028] Preferably, the tilting table and the food cart body are connected by a hinge. The hinge is made of stainless steel, which effectively resists outdoor humidity, salt spray and other corrosive environments. It can work stably in environments from -20℃ to 60℃, making it suitable for use in all seasons in both the north and south.

[0029] Furthermore, the nitrogen spring and piston rod, key structural components in this embodiment, utilize standardized interfaces, allowing for quick replacement and convenient maintenance, making them more suitable for small and medium-sized food cart manufacturers and individual operators. This embodiment also features a compact and lightweight design, employing a laterally folding nitrogen spring layout to reduce the space occupied by the mechanism and ensure the portability of the food cart.
