[0042] FIG. 1 is a perspective view of a vehicle storage cart capable of autonomous driving according to the present invention.

[0043] Referring to FIG. 1, a vehicle storage cart (100) capable of autonomous driving according to a preferred embodiment of the present invention may include a main body (110), a driving unit (120), a sensing unit (130), and a control unit (not shown).

[0044] The configuration of the present invention is described in detail as follows.

[0045]

[0046] First, the main body (110) forms the main body of the cart (100), and the main body (110) may have a receiving space (S) provided on its upper surface so that items can be stored. Additionally, a plurality of wheels (111) may be provided on the lower surface of the main body (110) so that the cart (100) can move.

[0047] Specifically, a plurality of partitions (113) may be provided on the upper edge of the main body (110) so that a receiving space (S) with an open upper side may be provided.

[0048] Referring to FIG. 2, the bulkhead (113) can be connected by a hinge (113a) so as to be foldable and unfoldable, and can be operated to automatically pivot at a predetermined angle by receiving power from an actuator. For convenience of explanation, the configuration of the actuator is omitted from the drawings in the present invention.

[0049] In addition, the wheels (111) may be installed at each corner of the bottom surface of the main body (110). Preferably, the main body (110) is formed in a rectangular shape when viewed in a planar view, and the wheels (111) are installed at each of the four corners of the bottom surface of the main body (110) to form a stable support structure.

[0050] Referring to FIG. 3, the wheel (111) can be foldably coupled toward the bottom surface of the main body (110) via at least one link (112).

[0051] In another embodiment, as shown in FIGS. 4a to 4c, at least two links (112) are connected in succession, each connected to receive power from a motor (not shown) so as to be pivotable, thereby allowing the height of the main body (110) to be adjusted.

[0052] Specifically, the link (112) may include a first link (112a) having one end rotatably coupled to the bottom surface of the main body (110) and the other end coupled to a wheel (111), and a second link (112b) having one end rotatably coupled to the other end of the first link (112a) and another wheel (111') coupled to the other end. Accordingly, either of the two wheels (111, 111') can be used depending on the rotation angle of the first link (112a) and the second link (112b) (see FIG. 4b).

[0053] Referring to FIG. 5, the main body (110) can have its volume minimized to that of a rectangular plate of a predetermined thickness when all of the plurality of partitions (113) and wheels (111, 111') are folded. Accordingly, when the cart (100) is not in use, it can be stored in a folded state in a dedicated storage groove (10) provided in the lower part of the vehicle (1) (see FIG. 6).

[0054] Meanwhile, the above main body (110) may be equipped with a battery module (not shown) so that it can be automatically charged using the power of the vehicle (1) when stored in the dedicated storage groove (10).

[0055] The above battery module is equipped with a smart battery system capable of bidirectional power exchange between the vehicle (1) and the cart (100), and can be used as a power source to operate the vehicle cart (100). In addition, the battery module can be used as an auxiliary battery to charge various devices, including the user's mobile phone.

[0056]

[0057] Referring again to FIG. 1, the driving unit (120) may be equipped with a motor (121) that supplies power to a plurality of wheels (111) so that the main body (110) can move. In the drawings of the present invention, the configuration of the motor is shown minimally for convenience of explanation.

[0058]

[0059] The above detection unit (130) may be equipped with a plurality of sensors (131) so that the main body (110) can follow behind the user or drive autonomously toward a predetermined destination.

[0060] Specifically, a plurality of sensors (131) constituting the detection unit (130) may be provided with a front or rear side in the direction in which the main body (110) moves.

[0061] In this case, the plurality of sensors (131) may selectively include at least one or more of LiDAR, cameras, radar, and ultrasonic sensors so as to recognize information including the shape, distance, and height of a user or surrounding objects. Since the configuration enabling autonomous driving via these plurality of sensors (131) can utilize previously known configurations, the specific operating principle thereof is omitted in the present invention.

[0062] In addition, the above-mentioned sensing unit (130) can measure the weight of an item stored in the receiving space (S) and can use the measured weight as data to determine whether it exceeds a reference value.

[0063]

[0064] The above control unit can control each of the above-mentioned components based on data measured by the sensing unit (130) and artificial intelligence (AI).

[0065] That is, the control unit stores the cart (100) in a dedicated storage groove (10) (see FIG. 6) at the bottom of the vehicle (1) when not in use, and can automatically pull out and operate the stored cart (100) so that the user can use it during various outdoor activities where shopping or transporting goods is required.

[0066] Specifically, referring to FIG. 7, the control unit can rotate the wheels (111, 111') to move the cart (100) outward for withdrawal from the dedicated storage groove (10). The withdrawn cart (100) can be used in various modes desired by the user, and can perform tasks such as tracking the user and following them through a tracking function, or driving autonomously to a predetermined target point depending on the situation.

[0067] Meanwhile, the vehicle cart (100) may have a tripod or a warning light (115) installed on its main body (110). Accordingly, in the event of an emergency situation, including an accident involving the vehicle (1), the tripod or warning light (115) can be activated after moving a certain distance from the vehicle (1) to warn other vehicles near the road of the accident situation, thereby preventing a secondary accident. In this case, the tripod is normally installed embedded within the main body (110) so as not to interfere with the storage of items, and can operate by receiving power and rotating out in an emergency.

[0068]

[0069] The vehicle storage type cart (100) capable of autonomous driving according to the present invention, having the above configuration, has a partition (113) and a wheel (111) of the main body (110) configured to be foldable so that it can be automatically stored in a dedicated storage groove (10) of the vehicle (1) with a minimal volume when not in use.

[0070] In addition, when using the above cart (100), autonomous driving is possible, so the process of transporting goods can be easily performed automatically in shopping or various situations.

[0071]
