Description

Technical Field

[0001] This utility model relates to a mobile body. Background Technology

[0002] Previously, a rechargeable mobile device was known, consisting of a main body supported by multiple legs and moving through the walking motion of the legs. In such devices, to avoid interference with the legs as they move around the main body, the charging port is typically located on the upper surface or side of the main body. However, this structure requires the charging port to be located on the upper or side of the main body to avoid interference, thus necessitating a large installation space during charging. Consequently, designing an automatic charging or storage layout within a limited space may result in reduced space utilization efficiency. Utility Model Content

[0003] One objective of this invention is to provide a mobile device that can reduce the installation space required for charging, improve storage capacity, and achieve stable charging operation.

[0004] The first technical solution is a mobile body, characterized in that it includes multiple legs, a main body supported by the multiple legs, and a charging port disposed on the lower surface of the main body on the inner side of the multiple legs. The multiple legs are composed of four legs arranged in a point-symmetric manner with respect to the center point of the main body in a plan view. By folding the four legs, the main body can be made into a standby posture with a low position. When in the standby posture, the charging port opens from between the legs toward the lower part of the main body.

[0005] This reduces the installation space required for charging and improves storage capacity.

[0006] The second technical solution is based on the first technical solution, wherein the charging port is configured as a charging connection part that can be connected to an external charging device from below.

[0007] Therefore, because the charging port is designed as a connector that can be connected to an external charging device from below, the charging connector can be automatically or easily connected while the mobile body is in a low standby position. This significantly improves workability during charging, making it particularly suitable for automated docking charging systems in unmanned or autonomous mobile robots. Furthermore, the lower connection structure helps to suppress the exposure of external cables, contributing to improved appearance and dust and water resistance.

[0008] The third technical solution is based on the first technical solution, where, when the main body is in a standby posture by folding the four legs, the charging port is located within the space enclosed by the legs.

[0009] Therefore, when the main body is in a standby position by folding down its four legs, the charging port is located within the space enclosed by the legs, effectively preventing damage from external contact or impact during charging. This improves the protection of the charging port and enhances its long-term reliability. Furthermore, by placing the charging port within the protective space inside the legs, both design aesthetics and safety are achieved while maintaining an overall aesthetic appearance.

[0016] The following combination Figures 1 to 6 This document details one embodiment of the seated movable body 10 disclosed herein. Figure 1 A perspective view showing the overall structure of the movable body 10 with a seat is shown. Figure 2 A perspective view showing the standby posture of the mounted mobile body 10.

[0017] In the diagram, arrow FR indicates the front of the seat, arrow UP indicates the top of the seat, and arrow LH indicates the left side of the seat. Unless otherwise specified, front-back, up-down, and left-right directions refer to the front-back direction of the seat, the up-down direction of the seat, and the left-right direction of the moving body with the seat, respectively. Unless otherwise stated, each element is not limited to a single element and may consist of multiple elements. Identical or substantially identical elements in the diagram are marked with the same symbol, and repeated descriptions are omitted.

[0018] like Figure 1As shown, the seated mobile body 10 is a personal mobile device that can move in a seated position. It mainly consists of a main body 20 supported by multiple legs 40 as a moving mechanism and a seat 30 mounted on the upper part of the main body 20.

[0019] The main body 20 has a built-in drive source and control device, which coordinates the drive of each leg 40, enabling the entire mobile body to move forward, backward, left, right, and up and down. Each part is described below.

[0020] The main body 20 has a housing forming an outer shell, which houses the drive power supply (battery), drive circuits for each motor, and control unit 12. Multiple legs 40 are mounted on the sides of the main body 20, and the upper part supports the seat 30.

[0021] like Figure 2 and Figure 3 As shown, the lower surface of the main body 20 is provided with a charging port 22 for connecting to an external power source, which can provide power when no one is riding in the vehicle or when the vehicle is in standby mode.

[0022] The seat part 30 is used to support the occupant in a seated position, and includes a seat surface 32 and a seat support part 34.

[0023] The seat surface 32 is installed at the upper center of the main body 20. In plan view, it is a trapezoid with slightly rounded corners. The seat surface is provided with cushioning material so that the occupant can sit comfortably for a long time.

[0024] The seat support 34 is a support structure surrounding the outer periphery of the seat surface 32, used to support the upper body (back and sides of the waist) of the occupant. Figure 4 As shown, the seat support 34 can rotate about a first pivot axis 36 in the seat width direction provided on the main body 20, thus allowing it to... Figure 4 It rotates between the vertical position shown by the solid line and the inclined position shown by the two-point chain line.

[0025] When in the upright position, the rear of the seat support 34 stands diagonally upward relative to the seat surface 32, which can wrap around the occupant from the back to the waist and side to maintain a stable sitting posture.

[0026] When in the tilted position, the rear of the seat support 34 tilts backward relative to the upright position. At this time, the seat surface and the backrest are basically horizontal, which can reduce the overall height of the seat and improve the storage capacity and standby space efficiency when no one is sitting.

[0027] In addition, the seat support 34 is ring-shaped and surrounds the entire circumference of the seat surface 32, so as to stably support the occupant's torso from all directions. The overall shape is curved, with a smooth appearance and good design aesthetics.

[0028] In this embodiment, the seat support 34 and the seat surface 32 can rotate separately or as a single unit. A ring-shaped structure is not mandatory; it is sufficient as long as it can surround at least a portion of the outer periphery of the seat surface 32 from the outside. For example, an arc-shaped structure is also acceptable.

[0029] The front of the seat support 34 is provided with an operating part 38 for operating the seated movable body 10 to move.

[0030] The control unit 38 consists of input devices such as buttons, touch sensors or joysticks. The occupant can operate the control unit while keeping their upper body stable by placing their hands on the seat support 34, thereby suppressing upper body swaying during operation and achieving stable and safe driving.

[0031] like Figure 3 As shown, the main body 20 is supported by four legs 40. The four legs 40 are arranged symmetrically with respect to the center point C of the main body 20 in the plan view.

[0032] like Figure 5 As shown, the leg 40 has a multi-joint structure formed by connecting multiple segments via joints, which both supports the main body 20 of the seated moving body 10 and enables movement through walking.

[0033] Each leg 40 is composed of a first segment 41, a second segment 42, and a third segment 43, which are connected by a first joint 51, a second joint 52, and a third joint 53, respectively.

[0034] In detail, the leg 40 extends from the main body 20 and is sequentially connected to the first segment 41, the second segment 42, and the third segment 43. A first joint 51 is provided between the main body 20 and the first segment 41, a second joint 52 is provided between the first segment 41 and the second segment 42, and a third joint 53 is provided between the second segment 42 and the third segment 43. Each joint is driven to rotate by multiple motors.

[0035] The first joint 51 is located between the main body 20 and the first segment 41, and can rotate about a first direction R1 axis by the rotational power of the first motor 61. The first direction R1 is perpendicular to the extension direction of the first segment 41 and corresponds to the up and down movement of the first segment 41. For example, it rotates about the output shaft of the first motor 61.

[0036] The second joint 52 is located between the first joint 41 and the second joint 42, and can rotate around a second direction R2 axis by the rotational power of the second motor 62. This second direction R2 is perpendicular to the first direction R1 and corresponds to the forward and backward, left and right movements of the second joint 42. For example, it can rotate around the output shaft of the second motor 62.

[0037] The third joint 53 is located between the second section 42 and the third section 43, and can rotate around a third direction R3 axis via the rotational power of the third motor 63. This third direction R3 is parallel to the first direction R1 and corresponds to the up-and-down movement of the third section 43. For example, the third motor 63 is mounted above the second section 42 and drives the third joint 53 via a pulley 64, thereby allowing the second section 42, which is closer to the ground, to be designed to be thinner, achieving space-saving movement.

[0038] The motors 61, 62, and 63 are driven independently and in coordination according to the control signal from the control unit 12, which includes the operation input from the operation unit 38.

[0039] Through this multi-joint structure, the legs 40 can move smoothly up and down and forward and backward, achieving a space-saving and highly stable walking motion. The number of legs is not limited to four; as long as there is at least one pair of legs, it is acceptable.

[0040] like Figure 4 As shown, a footrest 70 is mounted on the lower part of the main body 20. The footrest 70 includes an arm 74 extending from the lower part of the main body and a foot pedal 72 disposed at its end. The arm 74 can rotate about a second pivot 76 in the seat width direction disposed on the main body 20, thereby allowing for... Figure 4 Rotate between the usage position shown by the solid line and the storage position shown by the two-point chain line.

[0041] When in use, the footrest 72 is located between a pair of legs 40 connected to the front of the main body 20, allowing the occupant to place their feet on the seat surface 32 to restrict lower limb abduction. In this way, the occupant's lower limbs are kept between the pair of legs 40, preventing the legs from contacting the occupant's lower limbs during walking and ensuring a safe and comfortable riding posture.

[0042] When folded up, the footrest 72 passes between the pair of legs 40 connected to the front of the main body 20, protruding forward. At this time, the armrest 74 extends almost horizontally, reducing the space occupied by the seat in the vertical direction.

[0043] In addition, such as Figure 1 As shown, the seat width dimension L2 of the footrest 72 is set to be less than half of the ground contact distance L1 between the pair of legs 40. Therefore, the occupant's feet can be fixed in a position that maintains a sufficient distance from the pair of legs 40, further ensuring a safe, comfortable, and stable seating posture.

[0044] The following describes an example of the riding action of the seated mobile body 10.

[0045] When the occupant sits on the seat surface 32, the seat support 34 remains in an upright position, wrapping around the occupant from the back to the sides of the waist. Through the operation unit 38, the control unit 12 drives the legs 40, causing the seated moving body 10 to move by walking.

[0046] Next, an example of the standby posture and charging structure when no one is riding in the vehicle will be provided.

[0047] When no one is riding, the overall height can be lowered by tilting the seat support 34 backward and moving the footrest 70 to the storage position, which can save space along the vertical direction of the seat when in standby.

[0048] like Figure 2 and Figure 6 As shown, the seated mobile body 10 is in a standby posture when no one is riding in it or when it is charging. At this time, the legs 40 are folded, and the main body 20 is in a low standby posture. Furthermore, the charging port located on the lower surface of the main body 20 opens downward from between the folded legs 40.

[0049] like Figure 6 The following diagram illustrates an example of a charging structure inside vehicle 100. The seat-mounted mobile body 10 can autonomously move to a charging position inside vehicle 100. At this position, the charging port 22 located on the lower surface of the main body 20 is vertically aligned with the charging connection portion 106 on the floor 102 of vehicle 100. Thus, when the seat-mounted mobile body 10 enters a standby state, the charging port 22 automatically connects to the charging connection portion 106 on the vehicle 100 side, initiating power supply from the vehicle 100's battery 104 to the main body 20. With this structure, the seat-mounted mobile body 10 can be used as a seat in vehicle 100, achieving space-saving and efficient power management when stored inside the vehicle. Furthermore, the seat-mounted mobile body 10 can automatically adjust the seat support portion 34 to a tilted position during charging.

[0050] Therefore, this disclosure stabilizes the posture of the carrier 10 during charging by symmetrically arranging the four legs 40 relative to the center point C of the main body 20 in a plan view and folding these legs 40 so that the main body 20 is in a low-position standby. Simultaneously, the charging port 22 is located near the center of the lower surface of the main body 20 and opens downwards between the legs 40 in the standby posture, allowing for connection to an external charging device in a space-saving and efficient manner. This reduces the installation space required for charging, improves storage capacity, and enables stable charging operation.

[0051] Furthermore, since the charging port 22 is configured to connect to the charging connector 106 of an external charging device from below, the charging connector 106 can be automatically or easily connected even when the mobile body 10 is in a low-position standby posture, thereby significantly improving charging operability. This is particularly beneficial for the application of automatic docking charging systems in unmanned or autonomous mobile robots. Simultaneously, the lower connection structure helps to suppress external cable exposure, improving appearance and enhancing dust and water resistance.

[0052] Furthermore, when the main body 20 is folded into a standby position by the four legs 40, the charging port 22 is located within the space enclosed by the legs 40. Therefore, it can effectively prevent damage caused by external contact or impact during charging, thereby improving the protection and long-term reliability of the charging port 22. At the same time, by placing the charging port 22 in the protective space inside the legs, both design and safety can be considered while maintaining the overall appearance.
