Description

Technical Field

[0001] The utility model relates to the technical field of catering vehicles, in particular to an airborne mobile catering service vehicle. Background Art

[0002] Passenger aircraft are often equipped with mobile catering service carts. These carts are primarily used to transport food and other items to passengers during long-haul flights, allowing flight attendants to provide meals and drinks to passengers. A search revealed that existing technologies for functional improvements to mobile catering service carts on passenger aircraft primarily focus on the following aspects:

[0003] 1. The catering service vehicle itself does not have a heating function, and it is inconvenient to take heated food on the plane, such as the utility model patent named "A passenger aircraft catering vehicle (patent number: 201921007016)".

[0004] 2. The foot brake structure used in traditional technology is not conducive to the operation of the aircraft in a turbulent state. For example, the utility model patent "A handbrake-type passenger aircraft catering cart (patent number: 201820523136.4)" and the invention patent "A passenger aircraft catering cart (patent number: 201510370654.8)" use handbrake technology instead.

[0005] 3. Catering service vehicles are prone to colliding with passengers in bumpy conditions or when passengers are moving around. For example, the utility model patents "A civil aviation passenger aircraft dining vehicle with anti-accidental collision and protective function (patent number: 201820196854.5)" and "A passenger aircraft meal delivery component (patent number: 201621039778.4)" solve the anti-collision problem.

[0006] The above existing technologies have contributed to the improvement of mobile catering service vehicles and provided high reference value. From the perspective of the problems solved and the technical measures taken, the inventor believes that the following problems can be better solved and optimized:

[0007] 1. During the flight of a passenger plane, flight attendants must bend over or squat when taking items from the catering cart. This action may cause the flight attendants to lose their center of balance if the plane suddenly experiences turbulence.

[0008] 2. A large number of paper cups are used on airplanes, especially during catering services. A large number of paper cups need to be carried to mobile catering carts. However, in the existing technology, paper cups are placed randomly on the catering carts. This method may cause the paper cups to fall and scatter on the ground during the turbulence of the aircraft, and it is inconvenient for flight attendants to pick up the paper cups.

[0009] 3. During catering service, flight attendants need to push catering carts down the aisle to provide drinks and food to passengers. Beverages, such as Sprite and Coke, often come in tall bottles. The current method involves placing these bottles directly on the top of the catering cart. However, if the aircraft encounters turbulence and the bottle caps are not properly secured, the bottles can tip over, potentially causing the drinks to spill. This is especially true for beverages in glass bottles, which can easily break if dropped, causing even greater trouble.

[0010] Based on the above analysis, in order to solve the problems existing in the above practical process, the inventor team, after a long period of discussion and research, combined with the consultation and suggestions of relevant manufacturers, proposed an airborne mobile catering service vehicle to effectively make up for the above shortcomings.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings of the present invention specification to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] Example 1

[0040] refer to Figure 1-9 The technical solution of the embodiment provided by the present invention is as follows: an onboard mobile catering service vehicle, comprising a vehicle body 1 with an upper opening, with four universal wheels installed at the bottom. A sliding cover 11 is installed at the upper opening of the vehicle body 1 in a sliding connection with the inner wall of the vehicle body 1, and meals, drinks or storage boxes can be placed directly on the sliding cover 11; a beverage tray 2 is installed below the sliding cover 11 in a sliding connection with the inner wall of the vehicle body 1, and the length of the beverage tray 2 is shorter than the sliding cover 11; that is, the sliding cover 11 and the beverage tray 2 can both slide, and the sliding cover 11 and the beverage tray 2 can be slid to one side at the same time, and then the necessary items inside the vehicle body can be taken directly from the upper opening of the vehicle body 1, especially on an airplane, which has certain advantages over squatting to take items inside the vehicle body from the side. In addition, the above sliding connection can be made by installing a slide rail on the inner wall of the vehicle body 1, and then opening an adaptive groove on the side of the sliding cover 11 and the beverage tray 2.

[0041] The beverage tray 2 has a paper cup opening 21 and multiple beverage bottle openings 22. A paper cup holder 3 is detachably connected below the paper cup opening 21, with two symmetrical locking devices 5 mounted on its outer surface. A beverage bottle holder 4 is fixedly connected below the beverage bottle opening 22, equipped with a self-locking device 6 that securely holds the beverage bottles. This technical solution allows paper cups to be securely stored and retrieved as needed, effectively preventing them from being scattered and potentially tipping over. Furthermore, each beverage bottle is locked in place by a self-locking mechanism, effectively preventing accidental tipping during aircraft turbulence.

[0042] According to a preferred technical solution, the diameters of the plurality of beverage bottle openings 22 are set to be different to accommodate different beverage bottles, such as canned Sprite, bottled Coke, and the like.

[0043] Reference Attachment Figure 9 The preferred embodiment includes a temporary trash can 7 in the form of a horizontal triangular prism, wherein the trash can 7 has a hinge plate 71 , and one side of the hinge plate 71 is rotatably connected to the inner wall of the vehicle body 1 .

[0044] Example 2

[0045] Based on Example 1, refer to the attached Figure 3-5 In a preferred embodiment, the paper cup holder 3 includes a hollow paper cup tube 31, a first spring 32, and an inverted hollow support tube 33; one end of the first spring 32 is fixedly connected to the bottom surface of the paper cup tube 31, and the other end is fixedly connected to the top surface of the support tube 33.

[0046] In a preferred embodiment, the locking device 5 includes a shell 51 having a cavity 511, a second spring 52, a conductive rod 53, and a paddle 54 movably connected to the inner wall of the paper cup holder 3; one end of the second spring 52 is fixedly connected to the inner wall of the cavity 511, and the other end is fixedly connected to one end of the conductive rod 53, and the other end of the conductive rod 53 is in movably contact with the paddle 54.

[0047] In a preferred embodiment, the paper cup holder 3 is connected to the bottom of the paper cup opening 21 via threads.

[0048] The principle behind the above technical solution is as follows: To load paper cups, unscrew the paper cup holder 3 from under the paper cup opening 21, stack multiple cups, and place them into the paper cup holder 31. At this point, the force transmitted from the second spring 52 to the conductive rod 53 at one end of the pick 54 locks the cup. To remove a paper cup, lift the top cup upwards. The pick 54 instantly moves toward the inner wall of the support tube 33, compressing the second spring 52. Once the top cup is released, the pick 54 automatically returns to its original position due to the rebound force of the second spring 52. The first spring 32 then pushes the stacked cups upward, allowing the pick 54 to lock the top cup again. Paper cups are essential on airplanes and are used in large quantities. This technical solution effectively stores and removes paper cups, preventing them from scattering during aircraft vibrations. The force conditions at various locations in this technical solution are within the scope of understanding and mastery for those skilled in the art and will not be detailed here.

[0049] Example 3

[0050] Based on Example 1, please refer to the attached Figure 6-8 , preferably, the self-locking device 6 includes a clamping mechanism 61, a transmission mechanism 62, and a third spring 63; the clamping mechanism 61 is movably connected to the transmission mechanism 62, and one end of the third spring 63 is fixedly connected to the inner bottom surface of the beverage bottle rack 4, and the other end is fixedly connected to the bottom surface of the transmission mechanism 62.

[0051] In a preferred embodiment, the clamping mechanism 61 includes an anti-slip arc plate 611, a hollow guide sleeve 612, a connecting rod 613, a fourth spring 614 and a first wedge-shaped block 615 located inside the beverage bottle rack 4; one end of the guide sleeve 612 is fixedly mounted on the bottle wall of the beverage bottle rack 4; the connecting rod 613 passes through the guide sleeve 612, one end of which passes through the side wall of the beverage bottle rack 4 and is fixedly connected to the anti-slip arc plate 611, and the other end is fixedly connected to the first wedge-shaped block 615; one end of the fourth spring 614 is fixedly connected to the inner wall of the guide sleeve 612, and the other end is fixedly connected to the outer surface of the connecting rod 613.

[0052] In a preferred embodiment, the transmission mechanism 62 includes a force-bearing circular plate 621 and a vertical moving plate 622; the force-bearing circular plate 621 has connecting handles 6211 on both symmetrical sides; the upper end of the vertical moving plate 622 has a second wedge block 6221; the connecting handles 6211 on both sides are vertically fixedly connected to the lower end of the vertical moving plate 622; the second wedge block 6221 and the first wedge block 615 match each other and are movably contacted and connected to each other.

[0053] In a preferred embodiment, hollow conductive columns 41 are symmetrically provided on both sides of the beverage bottle rack 4 , and a movable opening 42 is provided near the bottom thereof to communicate with the interior of the conductive column 41 ; the connecting handle 6211 passes through the movable opening 42 and is fixedly connected to the vertical movable plate 622 .

[0054] The principle of the above technical solution is: when a beverage bottle filled with beverage is placed in the beverage bottle rack 4, the force-bearing circular plate 621 presses the third spring 63 downward by the gravity of the beverage bottle, and the force-bearing circular plate 621 moves downward. The connecting handle 6211 on the force-bearing circular plate 621 drives the vertical moving plate 622 to move downward, and the second wedge-shaped block 6221 on the vertical moving plate 622 presses the first wedge-shaped block 615 downward. The first wedge-shaped block 615 presses the anti-slip arc plate 611 toward the center position of the beverage bottle rack 4 through the connecting rod 613 (at this time the fourth spring 614 is in a stretched state), thereby locking the outer wall of the beverage bottle. Conversely, when the beverage bottle is lifted, the force of the third spring 63 causes the force-bearing circular plate 621 to move upward, and the connecting handle 6211 drives the second wedge-shaped block 6221 on the vertically movable plate 622 to move upward. At this time, the connecting rod 613 receives the force of the fourth spring 614, causing the anti-slip arc plate 611 and the first wedge-shaped block 615 to return to their original positions. This technical solution can utilize the gravity of the beverage and the beverage bottle, converting it into pressure on the outer wall of the beverage bottle, thereby firmly locking the beverage bottle in place and preventing it from tipping over during aircraft shaking. The force conditions in various locations of this technical solution are within the scope of those skilled in the art to understand and master during specific implementation and are not described here.

[0055] The above shows and describes the basic principles and main features of the present invention, as well as the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, from all perspectives, the embodiments should be regarded as illustrative and non-restrictive.
