Description

Technical Field

[0001] This utility model relates to the field of food delivery vehicle technology, specifically to an insulated food delivery vehicle that facilitates the picking up and placing of meals. Background Technology

[0002] Food delivery vehicles are mostly used in restaurants and hotels. When banquets are held, food delivery vehicles can be used to deliver food from the kitchen to the banquet hall in a timely manner. In winter or when the delivery distance is far, insulated food delivery vehicles will be used.

[0003] The utility model patent application with publication number "CN222171584U" discloses an insulated food delivery cart that is easy to pick up and put down. It mainly consists of an insulated box, a push-pull handle, a rotating side door, a slide bar, a food tray assembly, and a drive assembly. The technical solution uses a drive motor to drive the drive gear to rotate, which in turn drives the driven gear to rotate synchronously. The moving plate can move up and down with the steel wire belt. The pins on the side of the moving plate are inserted into the pin holes on the side of the food tray. In this way, the moving plate can drive the food tray assembly to move up and down along the linear direction of the slide bar, reducing the need for people to repeatedly squat down to pick up food and making it more convenient to pick up food.

[0004] The insulated food delivery cart disclosed in the aforementioned document has the following defects: the insulated food delivery cart is moved by bottom casters, but when it encounters uneven ground, it is easy to generate overall vibration during the pushing process. This vibration may cause liquid dishes such as soup and porridge in the cart to splash out from the edge of the plate, which will not only contaminate other dishes, but also dirty the inner wall of the insulated box. Utility Model Content

[0005] The purpose of this utility model is to provide an insulated food delivery cart that is easy to pick up and put down, and to solve the problem that when the ground is uneven, the food inside is prone to vibration during the pushing process.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to an insulated food delivery cart for easy loading and unloading of meals, comprising an insulated box, universal wheels mounted on the lower surface of the insulated box, a cover hinged to the upper surface of the insulated box, a door hinged to the outer surface of the insulated box, a buffer and shock-absorbing structure and a placement structure provided at the inner bottom of the insulated box, a lifting structure provided at one end of the buffer and shock-absorbing structure, and the placement structure located at the upper end of the buffer and shock-absorbing structure, the buffer and shock-absorbing structure comprising an outer shell, a buffer assembly and a damping telescopic rod provided inside the outer shell, the buffer assembly being configured in two sets, the buffer assembly comprising four connecting seats, a connecting rod being installed between each two adjacent connecting seats, and a slider being slidably connected to the outer surface of the connecting rod.

[0008] Furthermore, a spring is sleeved on the outer surface of the connecting rod, one end of the spring is installed on the outer surface of one of the connecting seats, the other end of the spring is installed on the outer surface of the slider, a support rod is hinged to the upper surface of the slider, a support plate is provided inside the housing, a support rod is hinged to the lower surface of the support plate, the placement structure includes two placement plates, a vertical rod is installed between the two placement plates, and one of the placement plates is installed on the upper surface of the support plate and the damping telescopic rod.

[0009] Furthermore, both of the placement plates have mounting grooves on their upper surfaces, and anti-slip pads are provided inside the mounting grooves.

[0010] Furthermore, the lifting structure includes a one-way screw, and two side plates are installed on the inner surface of the insulation box. The one-way screw is rotatably connected to the lower surface of one side plate. One end of the one-way screw passes through the insulation box and is equipped with a driven gear. A guide rod is installed on the lower surface of the other side plate. The other end of the guide rod is installed at the inner bottom of the insulation box. A drive motor is installed on the outer surface of the insulation box through a fixing component. A drive gear is installed at the output end of the drive motor. The drive gear meshes with the driven gear.

[0011] Furthermore, connecting blocks are installed at both ends of the outer shell. One connecting block is threaded to the outer surface of the one-way screw, and the other connecting block is slidably connected to the outer surface of the guide rod. A protective shell is installed on the outer surface of the insulation box, and the drive motor, the driving gear, and the driven gear are all located inside the protective shell.

[0012] Furthermore, the upper surface of the insulated box is provided with a baffle, a first magnetic block is installed on one side of the baffle, and a second magnetic block is installed on the outer surface of the cover plate, with the first magnetic block and the second magnetic block being magnetically connected.

[0013] This utility model has the following beneficial effects:

[0014] (1) The present invention, through the buffer structure, allows the placement structure and the support plate to move into the outer shell when the placement structure vibrates, and pushes the slider through the support rod, so that the slider moves axially on the connecting rod and gradually compresses the spring, so that the spring deforms and converts kinetic energy into elastic potential energy, thus buffering the impact force brought by the placement structure. When the placement structure moves into the outer shell, the output end of the damping telescopic rod contracts. When the placement structure slides upward and resets in the outer shell, the output end of the damping telescopic rod is stretched, thereby suppressing the spring rebound speed and avoiding vibration when the placement structure resets, thus achieving the effect of shock reduction.

[0015] (2) By turning on the drive motor, the output end of the drive motor drives the active gear to rotate. The active gear meshes with the driven gear, and when the active gear rotates, it drives the driven gear and the one-way screw to rotate. Since one end of the outer shell is connected to the one-way screw through the connecting block, the outer shell moves along the axial direction of the one-way screw when the one-way screw rotates. The other end of the outer shell slides along the guide rod through the connecting block, ensuring that the lifting process is smooth and does not deviate. When the outer shell is lifted, it drives the internal support plate and the placement plate to move up and down synchronously. When the placement plate rises, the height of the plate increases, making it easier for users to pick up and put down.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 As shown, this utility model is an insulated food delivery cart that facilitates the loading and unloading of meals. It includes an insulated box 1, with casters 2 installed on the lower surface of the insulated box 1, a cover plate 3 hinged to the upper surface of the insulated box 1, and a door 4 hinged to the outer surface of the insulated box 1. The inner bottom of the insulated box 1 is provided with a buffer and shock absorption structure 5 and a placement structure 6. One end of the buffer and shock absorption structure 5 is provided with a lifting structure 7. The placement structure 6 is located at the upper end of the buffer and shock absorption structure 5. The buffer and shock absorption structure 5 includes a shell 501. Inside the shell 501, there is a buffer assembly and a damping telescopic rod 503. The buffer assembly is set in two sets. The buffer assembly includes four connecting seats 50201. A connecting rod 50202 is installed between each two adjacent connecting seats 50201. A slider 50203 is slidably connected to the outer surface of the connecting rod 50202.

[0026] A spring 50204 is sleeved on the outer surface of the connecting rod 50202. One end of the spring 50204 is installed on the outer surface of one of the connecting seats 50201, and the other end of the spring 50204 is installed on the outer surface of the slider 50203. A support rod 504 is hinged to the upper surface of the slider 50203. A support plate 505 is provided inside the housing 501. The support rod 504 is hinged to the lower surface of the support plate 505. The placement structure 6 includes two placement plates 601. A vertical rod 602 is installed between the two placement plates 601. One of the placement plates 601 is installed on the upper surface of the support plate 505 and the damping telescopic rod 503.

[0027] In use, by pushing the handle on one side of the insulated box 1, the insulated box 1 is moved by the casters 2. When the insulated box 1 vibrates, the vibration is transmitted to the placement plate 601 inside the insulated box 1 and the food on the placement plate 601. When the placement plate 601 vibrates, the placement plate 601 and the support plate 505 move into the outer shell 501 and push the slider 50203 through the support rod 504. The slider 50203 moves axially on the connecting rod 50202 and gradually compresses the spring 50204, causing the spring 50204 to deform and convert kinetic energy into elastic potential energy, thus buffering the impact force from the placement plate 601. When the placement plate 601 moves into the outer shell 501, the output end of the damping telescopic rod 503 retracts. When the placement plate 601 slides upward and resets in the outer shell 501, the output end of the damping telescopic rod 503 is stretched, thereby suppressing the rebound speed of the spring 50204 and preventing vibration when the placement plate 601 resets, thus achieving the effect of shock absorption.

[0028] The upper surfaces of both placement plates 601 are provided with mounting grooves, and anti-slip pads 603 are provided inside the mounting grooves;

[0029] The anti-slip mat 603 is made of flexible rubber and has stripes on its outer surface, which can increase the friction between the placement plate 601 and the plate, ensuring that the plate is placed stably.

[0030] The lifting structure 7 includes a one-way screw 701. Two side plates 8 are installed on the inner surface of the insulation box 1. The one-way screw 701 is rotatably connected to the lower surface of one of the side plates 8. One end of the one-way screw 701 passes through the insulation box 1 and is equipped with a driven gear 702. A guide rod 703 is installed on the lower surface of the other side plate 8. The other end of the guide rod 703 is installed at the inner bottom of the insulation box 1. A drive motor 704 is installed on the outer surface of the insulation box 1 through a fastener 9. A drive gear 705 is installed at the output end of the drive motor 704. The drive gear 705 meshes with the driven gear 702.

[0031] Both ends of the outer shell 501 are equipped with connecting blocks 706. One connecting block 706 is threaded to the outer surface of the one-way screw 701, and the other connecting block 706 is slidably connected to the outer surface of the guide rod 703. The outer surface of the heat preservation box 1 is equipped with a protective shell 10. The drive motor 704, the drive gear 705 and the driven gear 702 are all located inside the protective shell 10.

[0032] When food needs to be taken out or placed, the cover plate 3 is pulled outward, causing it to rotate axially outward about the hinge point with the insulated box 1, exposing the food opening of the insulated box 1. Then, the drive motor 704 is activated, causing its output to rotate the drive gear 705. The drive gear 705 meshes with the driven gear 702, causing the driven gear 702 and the one-way screw 701 to rotate as the drive gear 705 rotates. Since one end of the outer casing 501 is connected to the one-way screw 701 via the connecting block 706... The mechanism works in such a way that when the one-way screw 701 rotates, the outer shell 501 moves axially along the one-way screw 701. The other end of the outer shell 501 slides along the guide rod 703 via the connecting block 706, ensuring a smooth lifting process without deviation. When the outer shell 501 lifts, it drives the internal support plate 505 and the placement plate 601 to move up and down synchronously. When the placement plate 601 rises, the height of the plate increases. When the placement plate 601 reaches the appropriate height, the drive motor 704 is turned off, and the lifting process stops. At this point, the food on the placement plate 601 can be picked up and placed.

[0033] The upper surface of the insulated box 1 is provided with a baffle 101, a first magnetic block 11 is installed on one side of the baffle 101, and a second magnetic block 12 is installed on the outer surface of the cover plate 3. The first magnetic block 11 and the second magnetic block 12 are magnetically connected.

[0034] When the cover 3 is rotated 90° to open, the first magnetic block 11 and the second magnetic block 12 automatically attract each other, forming a stable magnetic connection to prevent the cover 3 from tipping over during food retrieval.

[0035] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
