Description

[Technical Field]

[0001] The present invention relates to a cabin and a vehicle including the same. [Background technology]

[0002] Recently, various types of mobile vehicles have been developed to replace human labor. In particular, with the growth of the delivery industry, unmanned mobile vehicles capable of delivering food and other goods have been developed.

[0003] Such a moving body is formed by combining a cabin having a storage space for storing food, goods, etc., with a moving part that is connected to the cabin and moves the cabin. The cabin is provided with a tray on which the goods stored in the storage space are placed and a door that selectively opens and closes the storage space.

[0004] In the past, items were moved in and out of the storage space by the user directly pulling items from the tray out of the storage space or by pulling the items into the storage space. However, when the user directly pulled the items out of the storage space, there was a problem that the user's arm would come into contact with the door or the user's center of gravity would shift forward, causing the item to fall. In addition, the user had to bend down to check the storage space inside the cabin, which reduced convenience and made it difficult for users with weak joints to use.

FIG. DETAILED DESCRIPTION OF THE INVENTION

[0023] Some embodiments of the present invention will be described in detail below with reference to the accompanying drawings. When assigning reference numerals to components in each drawing, it should be noted that the same components are assigned the same numerals as much as possible even if they are displayed in different drawings. Furthermore, when describing the embodiments of the present invention, if it is determined that a detailed description of related known structures or functions would hinder understanding of the embodiments of the present invention, such a detailed description will be omitted.

[0024] A moving body 1 according to the present invention will be described below with reference to the drawings.

[0025] FIG. 1 is a perspective view of a moving body when a door is in a closed state according to an embodiment of the present invention.

[0026] 1, a moving body 1 refers to various structures that can move via moving parts such as wheels, propellers, etc. For example, such a moving body 1 may be provided as a vehicle, a drone, etc. Such a moving body 1 may include a cabin 10, a moving part 20, and a display part 30.

[0027] FIG. 2 is a bottom view of the cabin when the door is in a closed position according to one embodiment of the present invention.

[0028] 2, the cabin 10 can accommodate items and can store or transport the accommodated items. The cabin 10 can be selectively attached to a moving part 20. Such a cabin 10 includes a housing 100, a tray 200, a door 300, a motor 400, a power providing part 500, and a power transmission part 600.

[0029] The housing 100 forms the exterior of the cabin 10. For example, the housing 100 has a shape in which the horizontal width narrows toward the top. The housing 100 has an accommodating space 101, a door guide hole 102, and a tray guide hole 103 formed therein.

[0030] The receiving space 101 is formed inside the housing 100. Items (for example, parcels, food, etc.) are received in the receiving space 101. The door guide hole 102 is formed to penetrate the lower part of the housing 100 in the vertical direction H. The door guide hole 102 guides the movement of the door 300 relative to the housing 100. The door guide hole 102 may have a horseshoe shape, for example.

[0031] A plurality of door guide holes 102 are provided. The plurality of door guide holes 102 are arranged to be spaced apart in the left-right direction. For example, the plurality of door guide holes 102 may have a symmetrical shape with respect to a reference plane, which is an imaginary plane that passes through the center of the housing 100 and is perpendicular to the left-right direction. Each of the door guide holes 102 includes an inner section 102-1 and an outer section 102-2.

[0032] FIG. 3 is a diagram showing the power supply unit when the door is in a closed state according to one embodiment of the present invention, FIG. 4 is a diagram showing the power supply unit when the door is converted from a closed state to an open state according to one embodiment of the present invention, and FIG. 5 is a diagram showing the power supply unit when the door is in an open state according to one embodiment of the present invention.

[0033] 3 to 5, the inner section 102-1 is located radially inward of the first curve. The first curve is defined as a virtual curve extending along a guide region 514, which will be described later. The radially inward direction is defined as the direction of the first curve toward the center of curvature of the first curve. The radially outward direction is defined as the opposite direction to the radially inward direction. The inner section 102-1 may include a first inner section 102-11 and a second inner section 102-12.

[0034] The first inner section 102-11 forms one end of the door guide hole 102. The second inner section 102-12 forms the other end of the door guide hole 102. The first inner section 102-11 and the second inner section 102-12 are spaced apart from each other along the direction in which the first curve extends.

[0035] The outer section 102-2 forms the remaining portion of the door guide hole 102 other than the inner section 102-1. The outer section 102-2 may be located radially outward of the first curve. Both side ends of the outer section 102-2 are connected to the first inner section 102-11 and the second inner section 102-12, respectively. In addition, the outer section 102-2, the first inner section 102-11, and the second inner section 102-12 may be integrally formed, for example.

[0036] The tray guide hole 103 is formed to penetrate the lower part of the housing 100 in the up-down direction H. The tray guide hole 103 guides the movement of the tray 200. The tray guide hole 103 extends in the front-rear direction. A plurality of tray guide holes 103 are provided. The plurality of tray guide holes 103 are spaced apart in the left-right direction.

[0037] FIG. 6 is a perspective view of a cabin when the door is in an open state according to one embodiment of the present invention, and FIG. 7 is a bottom view of the cabin when the door is in an open state according to one embodiment of the present invention.

[0038] 6 and 7 , items stored in the storage space 101 are placed on the tray 200. The tray 200 moves relative to the housing 100 so as to be pulled out from the storage space 101 or pulled into the storage space 101. The direction in which the tray 200 is pulled out from the storage space 101 may be referred to as the pulling direction, and the direction opposite to the pulling direction may be referred to as the pulling direction. For example, the pulling direction may be forward, and the pulling direction may be backward. In other words, the tray 200 is provided to be movable in the front-to-rear direction relative to the housing 100.

[0039] The door 300 opens or closes the storage space 101 to the outside of the cabin 10. Such a door 300 is provided to be movable relative to the housing 100. A state in which the door 300 opens the storage space 101 to the outside is referred to as an open state. Also, a state in which the door 300 closes the storage space 101 to the outside is referred to as a closed state. Such a door 300 can move relative to the housing 100 between the open state and the closed state.

[0040] For example, the door 300 may be made of a transparent material so that the accommodating space 101 can be easily seen from the outside. A plurality of such doors 300 may be provided. The plurality of doors 300 may include a first door 310 and a second door 320.

[0041] The first door 310 is rotatably connected to one side (for example, the right side) of the housing 100 in the left-right direction. The second door 320 is rotatably connected to the other side (for example, the left side) of the housing 100 in the left-right direction. The first door 310 and the second door 320 are disposed symmetrically with respect to a reference plane. The first door 310 and the second door 320 move symmetrically with respect to the reference plane. For example, the path along which the first door 310 moves relative to the housing 100 and the path along which the second door 320 moves relative to the housing 100 are formed symmetrically with respect to the reference plane.

[0042] The motor 400 generates rotational power. For example, the motor 400 refers to a rotary motor including a rotor, a stator, a shaft, and a housing. Such a motor 400 may be fixed to the lower part of the housing 100. For example, a single motor 400 may be provided. As a detailed example, the cabin 10 according to an embodiment of the present invention is configured so that multiple components (for example, the tray 200, the door 300, the power supply unit 500, and the power transmission unit 600) are moved by the rotational power generated by the single motor 400. However, the present invention is not limited to this example, and multiple motors 400 may be provided.

[0043] The power providing unit 500 receives rotational power generated by the motor 400 from the motor 400. The power providing unit 500 can provide the received rotational power to the door 300 and the tray 200. For example, the door 300 can perform an opening and closing operation when power is provided from the power providing unit 500. Also, the tray 200 can perform an operation of moving in and out of the storage space when power is provided from the power providing unit 500. The power providing unit 500 is disposed at the bottom of the housing 100. The power providing unit 500 includes a door driving unit 510, a power converting unit 520, and a tray driving unit 530.

[0044] 2 , the door driver 510 can provide power to the door 300. For example, the door driver 510 transmits a first rotational power, which is a portion of the rotational power generated by the motor 400, to the door 300. The door driver 510 connects the motor 400 and the door 300 to each other. The door driver 510 includes a first region 511, a second region 512, a third region 513, and a guide region 514.

[0045] Referring again to FIG. 3, one end of the first region 511 rotates around a first rotation axis X1. The other end of the first region 511 revolves around the first rotation axis X1. The first rotation axis X1 is defined as an imaginary line that passes through one end of the first region 511 and extends in a first direction. For example, the first direction may be the up-down direction H. For example, the first region 511 is fixed to a first gear 610 (described later) and may rotate together with the first gear 610. This first region 511 is referred to as a first link.

[0046] The second region 512 is fixed to the first region 511. The second region 512 receives power from the first region 511. For example, the second region 512 is configured to move together with the first region 511. The second region 512 extends in a second direction. The second direction is defined as a direction intersecting the direction in which one end and the other end of the first region 511 move toward each other. In addition, the second direction is, for example, perpendicular to the up-down direction H.

[0047] For example, the second region 512 has a rail shape and guides the movement of the third region 513 in the second direction.

[0048] One end of the third region 513 is fixed to the door 300. The other end of the third region 513 is connected to the second region 512 so as to be movable in the second direction. The third region 513 receives power from the second region 512. For example, the third region 513 rotates about the first rotation axis X1 and moves linearly in the second direction due to the movement of the second region 512. The third region 513 includes a 3-1 region 513-1 and a 3-2 region 513-2.

[0049] The 3-1 region 513-1 forms one end of the third region 513. The 3-1 region 513-1 extends parallel to the second direction. The door 300 is fixed to one end of the 3-1 region 513-1, and the other end of the 3-1 region 513-1 is connected to one end of the 3-2 region 513-2.

[0050] The 3-2 region 513-2 extends from the other end of the 3-1 region 513-1 in a third direction. The third direction is defined as a direction intersecting the second direction and the direction of the first rotation axis X1. For example, the third direction is perpendicular to the second direction and the up-down direction H.

[0051] The other end of the 3-2 region 513-2 is disposed so as to face the second region 512. The other end of this 3-2 region 513-2 movably engages with the second region 512. The other end of this 3-2 region 513-2 extends in the second direction so as to be movable in the second direction relative to the second region 512. In addition, the 3-1 region 513-1 and the 3-2 region 513-2 are formed integrally, as an example.

[0052] The guide region 514 guides the movement of the other end of the first region 511. The guide region 514 may have an arc shape extending along a first curve. For example, the guide region 514 may have a rail shape that engages with the other end of the first region 511. The guide region 514 may be fixed to the lower part of the housing 100.

[0053] The power converting unit 520 converts the second rotational power, which is another part of the rotational power, into linear power. The power converting unit 520 is connected to the motor 400. One end of the power converting unit 520 can rotate about a first rotation axis X1. The other end of the power converting unit 520 can revolve about the first rotation axis X1.

[0054] For example, one end of the power conversion unit 520 is fixed to the first gear 610. For example, one end of the first region 511, the power transmission unit 600, and the first gear 610 are connected to each other along the vertical direction H.

[0055] The power conversion unit 520 has a long hole 520a formed therein, which penetrates in the up-down direction H and extends in a direction (long hole direction) where both ends of the power conversion unit 520 face each other. The long hole direction is defined as a direction intersecting the first direction and the front-rear direction. For example, the long hole direction is perpendicular to the up-down direction H. A tray protrusion 532 formed on the tray driver 530 is inserted into the long hole 520a.

[0056] The tray protrusion 532 is a protrusion having a shape that protrudes in a first direction (for example, downward). The tray protrusion 532 is inserted into the tray guide hole 103. When inserted into the long hole 520a, the tray protrusion 532 is provided so as to be movable relative to the power conversion unit 520 along the direction in which the long hole 520a extends. In other words, the tray protrusion 532 is inserted into both the tray guide hole 103 and the long hole 520a.

[0057] For example, the power conversion unit 520 has a link shape that connects the first gear 610 and the tray driving unit 530. The power conversion unit 520 is called a power conversion link.

[0058] When one end of the power conversion unit 520 rotates about the first rotation axis X1, the power conversion unit 520 can provide linear power to the tray driver 530, which is power for moving the tray driver 530 forward or backward. When the tray driver 530 moves forward or backward, the tray protrusion 532 can move relative to the power conversion unit 520 in the direction in which the long hole 520a extends.

[0059] 2 and 7, the distance between one end of the power conversion unit 520 and the rear end of the tray guide hole 103 in the front-rear direction is referred to as a first distance L1, and the distance between one end of the power transmission unit 600 and the front end of the tray guide hole 103 in the front-rear direction is referred to as a second distance L2. The first distance L1 and the second distance L2 are different from each other. For example, the second distance L2 is greater than the first distance L1.

[0060] As described above, since the first distance L1 and the second distance L2 are configured to be different from each other, the linear movement speed of the tray driving unit 530 may not be constant while the power conversion unit 520 moves at a predetermined angular velocity.

[0061] For example, the greater the angle that the power converting unit 520 forms with an imaginary line extending in the left-right direction, the greater the movement amount of the tray driving unit 530 relative to the rotation amount of the power converting unit 520. As a detailed example, when the power converting unit 520 rotates forward from a state in which the power converting unit 520 is oriented parallel to the left-right direction, the movement amount of the tray driving unit 530 relative to the rotation amount of the power converting unit 520 gradually increases.

[0062] The tray driver 530 moves the tray 200 in the front-rear direction relative to the housing 100. The tray driver 530 may be fixed to the tray 200 (for example, fixed to the bottom of the tray 200). The tray driver 530 may move in the front-rear direction while inserted into the tray guide hole 103.

[0063] A plurality of power providing units 500 are provided. The plurality of power providing units 500 include a first power providing unit 501 and a second power providing unit 502 that are arranged symmetrically with respect to a reference plane. For example, the first power providing unit 501 is arranged relatively to the left, and the second power providing unit 502 is arranged relatively to the right.

[0064] For example, the rotational power generated by the single motor 400 is transmitted to only one of the first power providing unit 501 and the second power providing unit 502. For example, when the rotational power generated by the motor 400 is transmitted to the first power providing unit 501, the remaining power other than the first rotational power and the second rotational power is transmitted to the power transmitting unit 600 and the second power providing unit 502. In the following description, it is assumed that the rotational power generated by the motor 400 is transmitted to the first power providing unit 501.

[0065] The power transmission unit 600 transmits the rotational power received from the first power supply unit 501 to the second power supply unit 502. The power transmission unit 600 includes a first gear 610, a second gear 620, and a medium gear 630.

[0066] The first gear 610 receives rotational power from the motor 400. The first gear 610 is installed to rotate around a first rotation axis X1. The first gear 610 can rotate the first region 511 of the first power providing unit 501 and the power converting unit 520 around the first rotation axis X1.

[0067] The second gear 620 receives rotational power from the intermediate gear 630. The second gear 620 rotates about a second rotation axis, which is defined as an imaginary straight line extending in the up-down direction H and spaced apart from the first rotation axis X1 in the left-right direction.

[0068] The second gear 620 rotates the first region 511 of the second power providing unit 502 and the power converting unit 520 around the second rotation axis. For example, the first region 511 of the second power providing unit 502 and the power converting unit 520 are each fixed to the second gear 620.

[0069] The intermediate gear 630 is disposed between the first gear 610 and the second gear 620. The intermediate gear 630 receives rotational power from the first gear 610 and transmits the received rotational power to the second gear 620. A plurality of such intermediate gears 630 are provided.

[0070] The plurality of medium gears 630 include a first medium gear and a second medium gear. The first medium gear is a gear that meshes with the first gear 610 and the second medium gear. The first medium gear is disposed between the first gear 610 and the second medium gear in the left-right direction. The gear ratio between the first medium gear and the first gear 610 is the same as the gear ratio between the first medium gear and the second medium gear.

[0071] The second medium gear is a gear that meshes with the first medium gear and the second gear 620. The second medium gear is disposed between the second medium gear and the second gear 620 in the left-right direction. The gear ratio between the second medium gear and the second gear 620 is the same as the gear ratio between the first medium gear and the first gear 610.

[0072] The path along which the rotational power generated by the motor 400 is transmitted will be described in detail below.

[0073] The rotational power generated by the motor 400 is transmitted to the first gear 610. The first gear 610 transmits a portion of the received rotational power to the first power providing unit 501 and the remaining portion to the first medium gear.

[0074] Fig. 8 is a cross-sectional view illustrating the coupling structure between the tray, tray driver, and housing according to an embodiment of the present invention, showing the state before the tray driver moves forward. Fig. 9 is a cross-sectional view illustrating the coupling structure between the tray, tray driver, and housing according to an embodiment of the present invention, showing the state after the tray driver has moved forward.

[0075] Meanwhile, the moving body according to the present invention further includes a feature for making the distance that the tray 200 moves in the front-back direction greater than the distance that the tray driving unit 530 moves in the front-back direction, which has the advantage that the tray 200 can move in the front-back direction at a faster speed.

[0076] To achieve the above object, the tray driving unit 530 according to the present invention further includes a belt member 534 having a cross-sectional shape of a closed curve, and a rotating member 536 that is rotatably provided in close contact with the belt member 534. More specifically, as shown in Figures 8 and 9, the belt member 534 is provided to extend along the front-rear direction of the moving body, and has a bent shape with two rotating members 536 that are spaced apart from each other in the front-rear direction.

[0077] Here, one side of the belt member 534 may be fixed to the housing 100, and the other side of the belt member 534 may be fixed to the tray 200. For example, the housing 100 may include a lower plate 110 that is provided in a lower region of the vehicle and cabin and is provided to face the tray 200 in the vertical direction, and the one side of the belt member 534 is fixed to the lower plate 110. Meanwhile, the above-mentioned door guide hole 102 and tray guide hole 103 are formed in the lower plate 110. FIGS. 8 and 9 show a state in which the lower plate 110 is provided below the tray 200 and the tray driver 530 and is provided to face the tray 200 in the vertical direction with the tray driver 530 interposed therebetween. In this case, the one side of the belt member 534 may be formed in an upper region based on the rotating member 536, and the other side of the belt member 534 may be formed in a lower region based on the rotating member 536.

[0078] 8, when the tray driver 530 moves forward as the motor is driven after the tray driver 530 is installed at the rear (i.e., after the tray is in a state before moving forward), the tray driver 530 must move forward while the portion of the belt member 534 fixed to the lower plate 110 does not move in the front-to-rear direction. Therefore, the tray 200 can move forward by a distance equal to the sum of the distance the tray driver 530 moves forward and the distance the upper region of the belt member 534 moves forward.
