[0011] Generally, a wheel is structured such that a tire is installed on the outer circumference of the wheel as a rim, a wheel axle, bearings, and a hub are installed in the center of the wheel, and spokes are installed between the hub and the rim.

[0012] Recently, electric bicycles equipped with hubless wheels that do not have a wheel axle, bearing, or hub inside the rim are being proposed.

[0013] FIG. 1 is an example diagram showing a hubless wheel for an electric bicycle with an advertising function according to the prior art.

[0014] As shown in FIG. 1, an advertising board (30) combining letters, numbers, and arbitrary shapes is installed inside the hubless wheel (20) of an electric bicycle (10) to provide an advertising effect.

[0015] The hubless wheel (20) is configured to include an outer rim (22) configured to rotate in place on the outer circumference of an inner rim (21) and a tire (23) installed on the outer rim (22).

[0016] This hubless wheel (20) has a simple overall configuration, and an advertising board (30) is installed in the space where there is no fork or hub.

[0017] The advertising board (30) is installed so that it is fixedly installed on the hubless wheel (20) by installing a mounting bracket (11).

[0018] However, advertising boards on hubless wheels according to conventional technology are configured to simply create and provide advertising content using text, numbers, and shapes. Since they cannot be changed to advertising information other than that installed once, there is a problem in that it is difficult to provide diverse advertising information.

[0019] In addition, while advertising boards on hubless wheels according to conventional technology can identify advertising content at night or in dark places using LEDs, there is a problem in that impacts generated during movement are directly transmitted to the LEDs, causing them to be easily damaged.

[0020] To solve these problems, the present invention aims to provide a hubless wheel display device that provides real-time advertising information by equipping a hubless wheel of an electric mobility vehicle with a display device for image output, and outputs advertising information through the display device based on the location of the electric mobility vehicle, and a location-based advertising system using the same.

[0021] To achieve the above objective, one embodiment of the present invention is a hubless wheel display device comprising: a display unit installed on a hubless wheel to output any advertising information; and a damper unit installed along the perimeter of the display unit to absorb shock transmitted from the hubless wheel.

[0030] In addition, the display device according to the above embodiment is characterized by transmitting GPS location information received through the GPS sensor unit to the management terminal via the electric mobility.

[0031] In addition, the management terminal according to the above embodiment is characterized by controlling the display device to output the optimal matching advertising information by comparing the current location analyzed based on the GPS location information with the location information-based advertising information received from the advertiser terminal.

[0032] In addition, the management terminal according to the above embodiment analyzes whether any advertising target store requested through an advertiser terminal is detected within a certain radius range based on current location information, and if one or more advertising target stores are detected, controls the display device to output advertising information linked to the advertising target stores, wherein the management terminal controls the display device to output the advertising information sequentially by ranking it based on preset conditions.

[0033] In addition, the electric mobility according to the above embodiment transmits image information captured using a camera to the management terminal, performs display and arbitrary operation control corresponding to guidance information and control information received from the management terminal, and the management terminal classifies the captured image information into one of a sidewalk, a bicycle path, or a roadway using an image processing program, generates guidance information and control information corresponding to the classification result, and transmits it to the electric mobility.

[0057] As shown in FIGS. 2 to 8, a hubless wheel display device (100) according to one embodiment of the present invention is configured to be installed on a hubless wheel (210) of an electric mobility (200) and to output any advertising information, and may be configured to include a housing (110), a display unit (120), a damper unit (130), a light-emitting unit (140), and a control module unit (150).

[0058] The display device (100) may be installed on a hubless wheel (210) having an inner rim (211), an outer rim (212) rotatably installed on the outer circumference of the inner rim (211), and a tire (213) installed on the outer rim (212).

[0059] That is, a pair of display devices (100, 100') may be installed facing each other with respect to the inner rim (211), a display unit (120, 120'), a damper unit (130, 130'), and a light-emitting unit (140, 140') may be installed on one side with respect to the housing (110, 110'), and a control module unit (150, 150') may be installed on the other side of the housing (110, 110').

[0060] The housing (110) is a disc-shaped member installed on the hubless wheel (210) and can be fixed to the inner rim (211) of the hubless wheel (210).

[0061] Additionally, the housing (110) may be configured with a groove (111) so that a part of the handle fork (202) connected to the handle (201) at the top is inserted.

[0062] Additionally, the housing (110) may have a plurality of flanges (112, 113) installed on one side so as to accommodate and mount a display unit (120).

[0063] The flanges (112, 113) can be configured to be spaced apart from the display unit (120) at a certain distance so that a damper unit (130) can be installed between them and the display unit (120).

[0064] The display unit (120) is configured to be installed on the flange (112) of the housing (110) to output advertising information, and can be configured as any one of an Electronic Paper Display (EPD), a Liquid Crystal Display (LCD), or an Organic Light Emitting Diodes (OLED), and preferably can be configured as an Electronic Paper Display.

[0065] The damper unit (130) is configured to absorb shock transmitted from the hubless wheel (210) by installing one or more between the housing (110) and the display unit (120), and may be configured to include a vibration damping unit (131), a spring (132), and a damping adjustment unit (133).

[0066] The anti-vibration part (131) is a plate-shaped member that blocks vibrations and shocks transmitted through the hubless wheel (210) and the spring (132), and may be composed of anti-vibration rubber or an anti-vibration pad, and may be installed between the display part (120) and the spring (132) along the outer surface perimeter of the display part (120).

[0067] The spring (132) is configured to absorb vibrations and shocks transmitted from the hubless wheel (210) to the display unit (120) by being installed between the housing (110) and the vibration damping unit (131), and may be configured as a coil-shaped spring.

[0068] The damping control unit (133) is installed between the outer surface of the display unit (120) and the vibration damping unit (131) to vary the range of movement of the spring (132) so that the vibration damping ability by the spring (132) can be adjusted.

[0069] That is, the damping control unit (133) operates according to a damping control operation control signal input from the control module unit (150) so that it is compressed or extended within a certain range, thereby allowing the movement range of the spring (132) to be varied, and can be configured as an actuator using hydraulics or gas, etc.

[0070] The damping control unit (133) adjusts the vibration damping ability of the damper unit (130) according to the magnitude of the impact, thereby enabling effective absorption and blocking of vibrations and shocks transmitted to the display unit (120) through the hubless wheel (210).

[0071] The light-transmitting part (140) is configured to protect the display part (120) and transmit display information output from the display part (120) to the outside, and can be composed of materials such as glass, silicon, and PC.

[0072] Additionally, the light-transmitting part (140) may have an anti-reflection coating formed on one side to improve transmittance and reduce reflectance, thereby maximizing visibility, and it is preferable that it be composed of a material with a relatively lower refractive index than the material forming the light-transmitting plate (140).

[0073] Additionally, the light-emitting part (140) is configured to maintain airtightness with the housing (110) through the sealing part (141).

[0074] The control module (150) is configured to output an operation control signal to the display unit (120) and can be installed on the other side of the housing (110), and can be configured to include a data communication unit (151), a control unit (152), an impact detection sensor unit (153), a GPS sensor unit (154), and an acceleration sensor unit (155).

[0076] The control unit (152) can output an operation control signal so that advertising information received through the data communication unit (151) or pre-stored advertising information is output to the display unit (120).

[0077] Additionally, when the control unit (152) receives an impact detection signal from the impact detection sensor unit (153), it compares the impact value corresponding to the impact detection signal with a preset reference value for damping control, and if the impact value is greater than or equal to the reference value as a result of the comparison, it can output an operation control signal for damping control to the damping adjustment unit (133).

[0078] That is, the control unit (152) maintains the damping control unit (133) in an extended state in a normal state so that the range of movement of the spring (132) is limited, and when an impact is detected, it compresses the damping control unit (133) to expand the range of movement of the spring (132), thereby controlling the damping ability to absorb vibration and impact of the spring (132) to be increased.

[0079] The shock detection sensor unit (153) is configured to detect physical shocks occurring on the hubless wheel (210). It may be configured as an acceleration sensor that outputs a shock detection signal based on a change in acceleration when a shock occurs, but is not limited thereto and may be configured using a spring mass system that operates in response to the shock.

[0080] The GPS sensor unit (154) can receive GPS coordinate information, that is, a GPS signal, at the current location where the display device (100) is moving, and calculate GPS location coordinate information.

[0081] Additionally, the GPS sensor unit (154) may be configured to further include a gyroscope sensor (not shown) that detects information on the direction of movement of the display device (100), and may output the calculated GPS position coordinate values ​​and the direction of movement information together.

[0095] The camera unit (230) is installed in the electric mobility (200) and outputs an image of the front side of the driving direction.

[0096] The mobility control unit (240) is configured to control the overall operation of the electric mobility (200), and can transmit advertising information to the display device (100) to be output, and can receive GPS location information received from the display device (100) and transmit it to the management terminal (300).

[0097] Additionally, the mobility control unit (240) can transmit an image captured through the camera unit (230) and any input information received through the interface unit (250) to the management terminal (300), display guidance information received from the management terminal (300) through the interface unit (250), or perform control of the operation of the mobility drive unit (260), such as on / off control and speed limiting, according to control information received from the management terminal (300).

[0098] The interface unit (250) can receive arbitrary input information, such as login information and payment information, from a user using the electric mobility (200), and operates to display information regarding the use, operation, and guidance of the electric mobility (200), and can be configured with an input / output means such as a touch screen.

[0099] The mobility drive unit (260) is configured to provide driving force so that the electric mobility (200) can drive, and may include a motor and a battery.

[0100] The management terminal (300) is connected to the electric mobility (200) via a network and can control the display device (100) to output the optimal matching advertising information by comparing the current location analyzed based on GPS location information received by the electric mobility (200) with the advertising information based on location information received from the advertiser terminal (400).

[0108] Artificial intelligence-based analysis models can perform classification of sidewalks, bicycle paths, and roadways using a deep learning model based on a Convolutional Neural Network (CNN).

[0109] Here, artificial intelligence-based analysis models can be seen as a type of analysis model created through a method called deep learning among machine learning.

[0110] Therefore, an artificial intelligence-based analysis model may also be used as a deep learning model or a deep learning analysis model.

[0111] Furthermore, machine learning is an application of artificial intelligence that enables complex systems to automatically learn and improve from experience without being explicitly programmed.

[0112] In addition, the accuracy and validity of machine learning models can partially depend on the data used to train them.

[0113] The mobility management unit (350) can search for location-based advertising information corresponding to the current location based on location information based on map data, classify the optimal matching advertising information, and control the classified advertising information to be output through the display device (100).

[0114] Additionally, the mobility management unit (350) may control the display device (100) to output advertising information linked to the advertising target store (e.g., "OO Snack Bar") when any advertising target store requested through the advertiser terminal (400) is detected within a certain radius range (e.g., 500m from the electric mobility (200)) based on the received current location information.

[0116] Additionally, the mobility management unit (350) can generate guidance information and control information corresponding to the result classified as one of a sidewalk, a bicycle path, or a roadway, and transmit it to the electric mobility (200).

[0117] Here, if classified as a sidewalk, the mobility management unit (350) can generate guidance information including display information and alarm signals guiding the prohibition of sidewalk passage and transmit it to the electric mobility (200).

[0118] Additionally, if classified as a bicycle path, the mobility management unit (350) can generate guidance information including display information and alarm signals to guide safe driving and then transmit it to the electric mobility (200).
