Description

Technical Field

[0001] The invention relates to a luggage case, and in particular to an intelligent electric luggage case suitable for boarding an aircraft. Background Art

[0002] A carry-on bag is a luggage specifically for boarders to carry with them and can be carried into the aircraft passenger cabin. According to the boarding regulations for air transport, the sum of the three dimensions (length, width, and height) of a carry-on bag is usually no more than 115 cm. Boarders usually use a 20-22 inch suitcase as a carry-on bag. The length, width, and height of the suitcase used for boarding are 36-42 cm, 22-26 cm, and 50-56 cm, respectively. These three dimensions are the outline dimensions of the suitcase, that is, the maximum dimensions of the three sides (including the size of the wheels). In practice, even if the sum of the three sides of the suitcase is slightly larger than 115 cm, it will not affect the boarder's ability to carry the suitcase into the aircraft passenger cabin. If the sum of the three dimensions of the suitcase carried by the boarder exceeds 125 cm, it needs to be checked in through the aircraft's cargo hold.

[0003] The electric luggage case includes a case body, power wheels, a battery, a motor for driving the power wheels to rotate, a motor control device connected to the motor signal, and a controller connected to the motor control device signal. The user sits on the case body and can easily move the electric luggage case by operating the controller to save physical effort. There are two power wheels, and the steering of the electric luggage case can be achieved through the speed difference of the two power wheels.

[0004] When manufacturers apply the driving structure of electric luggage to boarding luggage and assemble it into electric boarding luggage, they need to consider the installation structure of the two power wheels and the requirement that the sum of the three side dimensions does not exceed 125cm. Among them: if the wheelbase of the two power wheels is too narrow, when the boarder turns the electric boarding luggage, it is easy to cause the gravity to be too concentrated and biased to one side of the power wheel, so that the friction between the power wheel on the other side and the ground is too small, and then the power wheel on the other side is easy to slip, affecting the steering of the electric boarding luggage. In severe cases, the electric boarding luggage loses lateral stability and tilts to the left or right; if the wheelbase of the two power wheels is too wide, although the lateral stability of the electric boarding luggage is increased, it is easy to increase the turning radius and reduce the turning flexibility, and it is bound to reduce the length and / or height of the box; if the length of the box is too short, the longitudinal stability of the box will be reduced, causing the box to tip forward or backward; if the height of the box is too short, it will affect the bending comfort of the legs. In addition, if the height of the box is too high, the height of the center of gravity will increase and reduce the operating stability of the electric suitcase.

[0005] Therefore, during the research and development process, the manufacturer still needs to improve the installation structure of the two power wheels of the electric cabin case to enhance the user experience. Summary of the invention

[0031] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings, but does not limit the scope of protection of the present invention. The terms "front", "rear", "left", "right", "upper", "lower" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention.

[0032] See also Figure 1 and Figure 2 In this embodiment, a smart electric suitcase is provided, the length L+width W+height H of which is ≤1250mm, and can meet the maximum boarding size requirement. The boarder can not only ride on the smart electric suitcase, but also carry the smart electric suitcase to the passenger cabin of the aircraft, which is convenient for carrying with them.

[0033] In this embodiment, the smart electric luggage includes a box body 1 for users to ride on, a power wheel 2 installed on the box body, a control system for controlling the rotation of the power wheel 2, and a battery detachably connected to the box body 1. The battery is a rechargeable battery or a dry cell. The battery is electrically connected to the power wheel 2, the control system and other electronic devices on the box body and provides working power. The battery with a detachable structure is convenient for the smart electric luggage to be disassembled at any time during boarding security inspection to pass the security inspection smoothly. The control system includes a controller and an information processor. The controller signal is connected to the information processor, and the information processor is connected to the power wheel 2. The power wheel 2 is a wheel hub motor. Of course, in other embodiments, the power wheel 2 can also be a structure in which a reduction motor is connected to a wheel. The user sits on the box body and controls the controller by hand, and the operation instruction is processed by the information processor and converted into an electrical signal to drive the power wheel to rotate. The user can save physical energy and improve the user experience when riding on the smart electric luggage.

[0034] See also Figures 1 to 3In this embodiment, the outer wall of the box body 1 is recessed with a pedal part 4 for the user to step on. The pedal part 4 supports the user's feet, which improves the comfort of the user when riding. The structure is simple and easy to make. The pedal part 4 is molded and cast at one time by a mold when making the box body 1, so that the pedal part 4 and the box body 1 structure are integrated without splicing, which improves the firmness of the box body 1 structure. Specifically, the pedal part 4 is a groove structure recessed inward from the end surface of the outer wall. The pedal part 4 approaches the bottom end of the box body to provide a comfortable placement posture for the legs. There are two pedal parts 4, one of which (the left pedal part) is arranged at the edge junction of the left side wall and the front side wall of the box body 1, and the other pedal part 4 (the right pedal part) is arranged at the edge junction of the right side wall and the front side wall of the box body 1. The pedal part 4 has a pedal support surface 41 for the user to step on, which is convenient for the user to step on. The footrest support surface 41 extends obliquely from the rear to the front and lower side to meet the natural placement of the feet when the human body is sitting. The footrest support surface 41 is convexly provided with anti-skid patterns (not shown in the figure) to increase the friction between the user's feet and the footrest portion 4. When the user sits on the box 1, the two feet are placed on the left footrest portion and the right footrest portion respectively. The left footrest portion and the right footrest portion are symmetrical arc-shaped groove structures. The groove structure of the arc-shaped groove is equivalent to the rib plate component supporting the box 1. The rib plate component is combined with the edge structure of the box 1, which can further increase the structural firmness of the box 1. Each footrest portion 4 at least supports part of the user's foot, such as: the front part, the middle part of the foot or the heel, so that the footrest portion 4 can not only support the user's feet, but also relatively increase the storage space of the box 1. Of course, in other embodiments, the size of the groove can also be increased to increase the contact area between the footrest portion 4 and the foot.

[0035] In another embodiment, there is one pedal part, which is disposed on the front side wall of the box. The pedal part is a groove structure that is recessed inward from the front side wall of the box. The groove structure runs through the box from left to right. Of course, the groove structure can also be recessed on a part of the end surface of the front side wall. When the user sits on the box, both feet are placed on the pedal part.

[0036] In another embodiment, there are two pedals, which are respectively arranged on the left and right sides of the front side wall of the box. Each pedal is a groove structure that is recessed inward from the front side wall of the box, and the groove structure is recessed on a part of the end surface of the front side wall. The two groove structures are arranged side by side. When the user sits on the box, the two feet are placed on the two pedals accordingly.

[0037] In another embodiment, there are two pedals, which are respectively arranged on the left and right walls of the box. The two pedals are respectively a left pedal and a right pedal. The left pedal is a groove structure that is recessed inward from the left wall of the box, and the right pedal is a groove structure that is recessed inward from the right wall of the box, and the two groove structures are symmetrically arranged. When the user straddles the box, the two feet are placed on the left pedal and the right pedal respectively.

[0038] See also Figure 1 , Figure 2 and Figure 4 In this embodiment, there are two power wheels 2, and both power wheels 2 are mounted on the rear side of the case 1 and are arranged side by side on the left and right sides of the case. The left power wheel and the right power wheel are located on the same axis. The smart electric suitcase also includes a universal wheel 3 mounted on the front side of the case, and the universal wheel 3 rotates driven by the power wheel 2. The number of universal wheels 3 can be one or two. The smart electric suitcase achieves steering through the speed difference between the two power wheels 2. In addition, the power wheels 2 are mounted on the rear side of the case and the universal wheels 3 are mounted on the front side of the case. When the smart electric suitcase moves, the case will not swing, thereby increasing the directional stability of the smart electric suitcase during operation.

[0039] See also Figure 2 and Figure 4 In this embodiment, the width d of each power wheel 2 is 50-60 mm. Of course, the width of the power wheel 2 can also be 20 mm, 30 mm, 40 mm, 70 mm, etc. according to the design requirements of the smart electric luggage. The wheelbase B of the two power wheels is 175-245 mm. This wheelbase B is designed according to the three-dimensional dimensions of the boarding luggage, avoiding the defects caused by too narrow or too wide wheelbase. When the boarder turns while sitting on the smart electric luggage, the boarder's gravity can be evenly distributed on the two power wheels 2, avoiding any power wheel 2 from slipping on the ground, which is conducive to the steering of the smart electric luggage, has better steering performance, and also increases the lateral stability of the smart electric luggage. When the three-dimensional dimensions of the smart electric luggage for boarding increase, the wheelbase B will also increase accordingly; similarly, when the three-dimensional dimensions decrease, the wheelbase B will also decrease accordingly. Conversely, when the wheelbase B changes, the three-dimensional dimensions of the smart electric luggage will also change accordingly. Of course, when assembling the smart electric suitcase, you can also choose power wheels of different widths according to different wheel bases to maximize the wheel base.

[0040] The distance D between the two end faces of the two power wheels 2 = wheelbase B + + . The length L + width W + height H of the smart electric suitcase ≤ 1250 mm. The length L of the smart electric suitcase is the maximum length of the smart electric suitcase in the front-to-back direction. The width W of the smart electric suitcase is the maximum width of the smart electric suitcase in the left-to-right direction. Wherein: the width W of the smart electric suitcase depends on one of the distance D between the two end faces of the two power wheels 2 and the width W' of the box body 1. When the distance D between the two end faces of the two power wheels 2 is less than or equal to the width W' of the box body 1, the width W of the smart electric suitcase is the width W' of the box body 1; when the distance D between the two end faces of the two power wheels 2 is greater than the width W' of the box body 1, the width W of the smart electric suitcase is the distance D between the two end faces of the two power wheels 2. The height H of the smart electric suitcase is the maximum height of the smart electric suitcase in the up and down direction (including the height of the power wheels 2).

[0041] In this embodiment, the smart electric luggage suitable for boarding can meet the maximum boarding size requirements. When the wheelbase B of the two power wheels 2 changes, the length L, width W and height H of the smart electric luggage will also change accordingly, as shown in the following table. The unit of the values ​​in the table is millimeter (mm).

[0042]

[0043] It should be noted that the above-mentioned attached table lists the corresponding length L, width W, and height H of the smart electric luggage when the wheelbase B is 175mm, 185mm, 195mm, 205mm, 215mm, 225mm, 235mm, and 245mm. The reference values ​​are not restrictions on the three-sided dimensions of the smart electric luggage. The values ​​of the above-mentioned wheelbase B are representative wheelbase values ​​between 175 and 245mm. When the wheelbase B is 178mm, 183mm, 198mm, 207mm, 238mm, etc., the length L, width W, and height H of the smart electric luggage will also change accordingly. At the same time, the problem of the smart electric luggage being too long, too high, or too low in height is overcome; when the corresponding width of the smart electric luggage is increased, the defects caused by the wheelbase being too narrow or too wide are also avoided.

[0044] In addition, the present invention takes into account the different transportation regulations of different airlines in the world and the regulations of IATA (International Air Transport Association). In order to further meet the boarding size regulations of the smart electric suitcase, the length L+width W+height H of the smart electric suitcase is ≤1150mm, and the wheelbase B of the two power wheels is 175-225mm, so as to cope with different transportation regulations when riding on airplanes of different airlines and meet boarding requirements, thereby improving the boarder's experience of using the smart electric suitcase.

[0045] In this embodiment, the controller is held in the hand of the user. The controller is connected to the information processor by wired signals. The controller is provided with control buttons for moving forward, moving backward, turning left, turning right, accelerating and decelerating.
