Accordingly, when the handle 230 is introduced into the body 110 , the surface of the body 110 on which the handle 230 part is disposed does not protrude and the handle 230 part may maintain a flat surface.

According to one embodiment, the car-shaped children's travel trolley can identify the real-time location of the occupant and operate in a danger mode when a part of the occupant's body is in the danger zone out of the safe zone. Specifically, the children's travel trolley may include a camera that identifies the body of the occupant in real time. The camera may be installed on the body or the handle, and may be disposed toward the occupant. The camera may photograph the occupant, and may transmit the captured image to the controller. The controller may identify the real-time location of the occupant's body, such as the occupant's head, body, arms, and legs, by using the occupant's image captured by the camera.

When a part of the occupant's body is in the safe area, the controller may operate the plurality of wheels in a normal mode to rotate them normally. The safety area is a space adjacent to the boarding part, and may be an upper area of the boarding part closest to the body. When the occupant sits on the boarding part, a portion of the upper body of the occupant may be exposed to the upper region of the boarding part without overlapping the body. As such, the upper region of the boarding part in which a part of the upper body of the passenger is exposed may be a safety area. When the body of the occupant is in the safe area, the control unit may determine that the occupant is safe, and the child travel trolley may be operated in a normal mode. In the normal mode, the plurality of wheels may be rotated by the controller or the user, and thus, the children's travel trolley may move normally.

Alternatively, when a part of the occupant's body is in the danger zone, the controller may operate the plurality of wheels in the danger mode. The danger zone is an area where it is determined that the safety of the occupant is not guaranteed when a part of the occupant's body is in the danger zone. For example, the danger area may include an upper area of the safety area, a side area of the body adjacent to the ground, and an area adjacent to the plurality of wheels.

Specifically, when the occupant stands up without being seated in the seat of the passenger, a part of the occupant's body may be located in the upper region of the safety area. An occupant who stands up from a moving children's travel trolley may face a fall risk. Accordingly, the upper area of the safe area may be included in the hazardous area.

In addition, the occupant can touch the ground with their hands along the side of the body by stretching their arms. A risk of injury may exist if the child's travel trolley is in motion and touching the ground with hands. Accordingly, the side area of the body adjacent to the ground may be included in the danger area.

In addition, the occupant may touch the wheel with his/her hand by stretching his/her arm. If you touch the wheels on a moving children's travel trolley, there may be a risk of getting your hands caught in the rotating wheels. Accordingly, an area adjacent to the plurality of wheels may be included in the hazardous area.

The control unit may operate the children's travel trolley in a danger mode when a part of the occupant's body is located in the danger zone. Specifically, when the body of the travel trolley for children is moving, the control unit may gradually decelerate the body in the danger mode. For example, the body may be moving at a specific speed, and when the danger mode is activated, the speed may be decelerated with an acceleration less than or equal to a preset acceleration. As such, if the body is not decelerated slowly but rapidly decelerated, such as to a sudden stop, an occupant located in a dangerous area may lose his/her center of gravity and may have an accident outside the boarding part. Accordingly, the control unit may decelerate the body of the children's travel trolley moving in the danger mode below a preset acceleration, and the children's travel trolley may gradually stop. In this case, the preset acceleration may be changed by the user.

When the body of the travel trolley for children is stationary, the control unit may maintain the stationary state of the body in the danger mode. For example, the occupant may place a part of the body in the danger zone, such as when the child travel trolley is stationary and the occupant stands up. In such a state, when the travel trolley for children abruptly moves, an accident such as a occupant detaching from the boarding unit and falling may occur. Therefore, when the body is stopped, the control unit may maintain the state in which the rotation of the plurality of wheels is stopped as a dangerous mode to maintain the body in a stopped state.

According to an embodiment, the travel trolley for children may generate a warning sound or emit a warning light in the danger mode. Specifically, the travel trolley for children may generate a warning sound when a part of the occupant's body is located in the danger zone.

In addition, when a part of the occupant's body is located in the danger area, the travel trolley for children may emit a warning light corresponding to the danger area in which the body part is located. For example, when a part of the occupant's body is located in a danger area that is an upper area of the safety area, a warning light installed on the handle may be lighted. In addition, when a part of the occupant's body is located in the side area of the body adjacent to the ground, a warning light installed in the side area of the body may be lighted. In addition, when a part of the occupant's body is located in a danger area adjacent to the plurality of wheels, warning lights installed on the plurality of wheels may be lighted.

However, the present invention is not limited thereto, and only the warning light located on the handle may be lit in the danger mode.

According to an embodiment, the safety area may be changed according to the occupant. A length of a portion of the occupant's upper body exposed to the upper portion of the boarding unit when the occupant is seated may be different depending on the length of the occupant's upper body. Accordingly, the user may input information on the height of the occupant in the travel trolley for children by using the input unit, and based on this, the controller may calculate the height of the safety area according to the height of the occupant.

In addition, the children's travel trolley may further include a storage unit, and the storage unit may store information on the height of the occupant and the height of the safety area. For example, the storage unit may store information about the height of the first occupant and the height of the safe area, and may store information about the height of the second occupant different from the first occupant and the height of the safe area. Accordingly, the storage unit may store information on the height of each of the plurality of passengers and the height of the safety area.

The children's travel trolley may receive an input from the user that the passenger riding on the child travel trolley is a first passenger among the plurality of passengers. Correspondingly, the control unit of the travel trolley for children may change the information on the safety area to information on the safety area of the first occupant stored in the storage unit. Accordingly, the safe area may be changed to the safe area of the first occupant.

According to an embodiment, the camera may photograph the occupant riding in the boarding unit, and the controller may calculate a safety area tailored to the occupant by using the image of the occupant captured by the camera. Specifically, the camera may generate an image of the occupant by photographing the occupant sitting on the boarding unit, and may transmit the image to the control unit. The controller may calculate the position of the uppermost portion of the head of the occupant in a state in which the occupant is seated in a chair of the occupant by using the image of the occupant. In addition, the controller may calculate the height of the safety area based on the position of the uppermost end of the head of the occupant. The control unit may distinguish the safe area from the dangerous area based on the height of the safe area fitted to the occupant. Accordingly, a safe area and a dangerous area may be automatically calculated according to the height of the occupant.

According to an embodiment, when the storage space is opened, the controller may stop the movement of the children's travel trolley and maintain a stationary state. The storage space disposed on the front or rear portion of the body may be opened by the user. When the storage space is opened, the control unit may maintain a state in which the rotation of the plurality of wheels is stopped, and thus the movement of the body may be stopped. Accordingly, a user who opens the storage space to put or remove an object may not be exposed to a risk as the children's travel trolley moves.

According to an embodiment, the travel trolley for children may further include a temperature controller for controlling the temperature of the boarding part. The temperature control unit includes a heating wire installed in a chair that can increase the surface temperature of the seat of the passenger, a hot air fan that can increase the temperature of the inner space of the passenger, an air conditioner that can lower the temperature of the inner space of the passenger, and It may include at least one of an air circulator for air circulation.

The temperature controller may control the temperature of the boarding part in response to the user's temperature control input. Specifically, the user may input a desired temperature using an input unit installed on the handle or select an execution intensity of the temperature control unit, and the temperature control unit may adjust the temperature of the boarding unit in response thereto.

According to an embodiment, the temperature controller may control the temperature of the boarding unit based on information about the passenger stored in the storage unit. Specifically, information about the preferred temperature of a specific passenger, for example, the first passenger may be stored in a storage unit of the children's travel trolley. The first occupant may board the boarding part of the children's travel trolley and use the temperature control unit, and the temperature control unit may be operated to a specific temperature. The storage unit may store information on a specific temperature set when the first occupant uses the temperature controller as a preferred temperature of the first occupant. Thereafter, when the first occupant boards the boarding unit again, the storage unit may transmit the stored information on the preferred temperature of the first occupant to the temperature controller. The temperature controller may adjust the temperature of the boarding part in response to the preferred temperature of the first passenger.

According to an embodiment, the travel trolley for children may further include an external temperature measurement unit in addition to the temperature control unit. The external temperature measuring unit is a component that measures the temperature outside the children's travel trolley. The external temperature measuring unit may measure the external temperature of the travel trolley for children, and transmit information about the external temperature to the temperature control unit.

The temperature controller may adjust the temperature of the boarding part by using the information on the external temperature received from the external temperature measuring part. Specifically, when the external temperature is equal to or higher than a preset temperature, the temperature control unit may ask the user whether to execute the function for lowering the temperature of the passenger compartment, and receive an input from the user as to whether the function for lowering the temperature of the passenger compartment is executed. For example, a display that provides various information to the user may be installed on the handle, and the display may display information that the external temperature is above a preset temperature, and information on whether a function for lowering the temperature of the boarding part is executed. . The user may input an execution of a function for lowering the temperature of the passenger compartment using the display, and in response, the temperature controller may execute a function for lowering the temperature of the passenger compartment.

On the other hand, when the external temperature is below another preset temperature, the temperature control unit asks the user whether to execute the function to increase the temperature of the boarding part, and receives an input from the user on whether to execute the function to increase the temperature of the boarding part. . For example, the display installed on the handle may display information that the external temperature is equal to or higher than a preset temperature, and information on whether a function to increase the temperature of the boarding part is executed. The user may input an execution of a function to increase the temperature of the boarding part using the display, and the temperature controller may execute a function to increase the temperature of the boarding part in response thereto.

According to an exemplary embodiment, the temperature controller may recognize a occupant riding in the boarding part and control the temperature of the boarding part in response to both the recognized occupant and the external temperature. Specifically, the storage unit may store information about a specific passenger who boarded the boarding unit, for example, the first passenger. The storage unit includes identification information of the first occupant, information on a plurality of external temperatures when the first occupant is boarded, and information on the temperature of the boarding part set in response to each of the plurality of external temperatures when the first occupant boards can be saved. That is, the first occupant may board the boarding unit and use the children's travel trolley, and may move to a plurality of places having different external temperatures while riding the children's travel trolley. In each of the plurality of external temperatures, the boarding unit may maintain the temperature of the plurality of boarding parts in response to each of the plurality of external temperatures. Information on the temperature of the plurality of boarding units corresponding to each of the plurality of external temperatures may be stored in the storage unit.

The children's travel trolley may recognize that the first occupant boards the boarding unit, and the storage unit may transmit information about the temperature of the plurality of boarding units corresponding to each of the plurality of external temperatures stored in the temperature control unit.

And, when the left part of the long bar-shaped driving button is pressed, the control unit may control the plurality of wheels so that the plurality of wheels are directed in a direction in which the children's travel trolley rotates to the right and moves forward, for example, , it is possible to control the direction in which the front wheel of one pair of the plurality of wheels faces toward the direction in which the children's travel trolley can rotate to the right and move forward.

In addition, the controller may control the rotational force of the plurality of wheels and the direction in which the plurality of wheels are directed in response to an area in which the long bar-shaped driving button is pressed and the intensity of the pressing force. A direction in which the plurality of wheels are directed, that is, a direction in which the children's travel trolley travels, may be determined in response to a pressing area of the travel button as described above. And, the rotational strength of the plurality of wheels, that is, the rotational force of the plurality of wheels may be determined by the strength of pressing the travel button. For example, when the central region of the travel button is pressed, the controller may provide a driving force in a direction in which the travel trolley for children moves forward in proportion to the strength of pressing the central region of the driving button. When the right region of the driving button is pressed, the control unit may provide a driving force in a direction in which the travel trolley for children moves forward in proportion to the strength of pressing the right region of the driving button. In addition, when the left area of the travel button is pressed, the control unit may provide a driving force in a direction in which the children's travel trolley rotates to the right and moves forward in proportion to the strength of pressing the left area of the travel button.

According to an embodiment, the controller may provide a driving force to the travel trolley for children by providing a rotational force to the plurality of wheels in proportion to the strength of the force pressing the travel button.
