Description

Technical Field

[0001] This invention relates to a car racing system.

[0002] In particular, this invention allows players to enjoy a car racing game on the track with a control device (remote control) that is comparable to the atmosphere of real car racing, and can cause the car in front to leave the lane when the car accelerates and approaches the car in front during the race. Background Technology

[0003] Korean Patent Publication No. 10-1999-0068385 discloses a racing game system. On a track designed and manufactured with a specific shape and length, a knob is finely adjusted according to the degree to which the player pulls the trigger using a control device. The finely adjusted knob is converted into a digital pulse value, which is input to an analog-to-digital (AD) converter and an electronic gearbox, supplying appropriate direct current (DC) power. This supplies appropriate power to a drivable car connected to the track, thereby controlling the car's movement to the same degree as a real driver's fine-tuning. When the trigger is released, a powerful braking function is executed by supplying a momentary reverse current, thus providing a realistic and exciting car racing game experience.

[0004] Furthermore, the system can enhance the enjoyment of the game by installing components such as a first-place display component and a top speed measuring component. It can also ensure smooth competition even when different players participate consecutively by installing components such as a component for returning the car to its original position after the game ends. In addition, the system's durability can be improved, thereby reducing the failure rate of the device and extending its service life.

[0005] However, as mentioned above, the existing racing systems are simply technologies related to racing and cannot reproduce situations such as car accidents or damage that occur during actual racing. Therefore, there is a need to develop more exciting games. Summary of the Invention

[0043] [First Embodiment]

[0044] like Figure 1 , Figure 5 as well as Figure 7As shown, the car racing system of the present invention includes a lane 100, a car 200 and a remote controller 300. It is a system that allows multiple cars 200 traveling on the lane 100 to race against each other and repeatedly executes the process of multiple cars 200 leaving the lane 100 under specific conditions, thereby determining the car that is left on the lane 100 at the end as the winner.

[0045] The detachment of the vehicle 200 from the lane 100 can occur when the first locking device 225, which is located on the lower part of the vehicle 200, or more precisely on the second part 220, is unlocked under certain conditions and thus loses its center of gravity. This configuration, as described above, will be explained later.

[0046] The system of the present invention, as described above, includes a lane 100, a car (racing vehicle) 200, and a remote control 300.

[0047] like Figure 1 As shown, the lane 100 is configured with a specific curved shape and is configured in an optimal state for the vehicle 200 to drive in.

[0048] Guide rails 110 and 120, respectively, are provided on both sides of the lane 100 at a specific height from the bottom surface to ensure that the vehicle 200 does not detach during driving. However, the height of the guide rails 110 and 120 in the lane 100 needs to be set so that the vehicle can easily detach from the lane when overtaken by a vehicle behind. That is, it needs to be designed such that, for example, when the first locking device located under the vehicle is deployed to a specific angle, its height exceeds the height of the guide rails 110 and 120, thereby easily detaching from the lane 100.

[0049] The car 200 is designed so that it does not exceed the width and height of the guide rails 110 and 120 of the lane 100, and as Figure 2 As shown, the vehicle body can be divided into a first part 210, a second part 220, and a third part 230. The above-described configuration is for the purpose of explaining the locking device and the principle by which a vehicle traveling on lane 100 disengages from lane 100 due to the operation of the locking device.

[0050] The first part 210 is the front part of the car 200, and a first magnet 211 is provided on its lower surface.

[0051] The first magnet 211 is configured to induce the operation of the first and second locking devices equipped in other vehicles by reacting with the second magnets equipped in other vehicles. The reaction with the second magnets of other vehicles can be exemplified by attraction due to opposite polarities.

[0052] The first magnet 211 can be secured to the space formed in the lower part of the first portion 210 by a suitable coupling assembly. The coupling assembly is not limited to a specific type such as tape or screw.

[0053] The second part 220 is the middle part of the car 200 and is equipped with the first locking device 225.

[0054] The first locking device 225 is mounted on the bottom surface of the vehicle body. When it is locked by the first magnet 211 of the other vehicle while it is pressed against the bottom surface of the vehicle body, it will elastically move at a specific angle and cause the vehicle body to lift upward and lose its center, thereby causing the vehicle to detach from the lane 100.

[0055] That is, such as Figure 1 As shown, in order to achieve elastic movement, the first locking device 225 can be attached to a specific part of the bottom surface of the vehicle body via a spring hinge P. That is, when the first locking device 225 is released from its elastic attachment to a specific lower part of the second part 220 via the spring hinge P, the first locking device 225 will unfold to a right angle (rotational movement) and the vehicle body will be lifted a specific height from the lane 100. The vehicle body traveling at a specific speed will lose its center of gravity, tilt, and detach from the lane 100.

[0056] The spring hinge P is just one example and can be applied without limitation to any component that can elastically connect the first locking device 225 to the bottom surface of the second part 220 and unfold to a right angle when unlocked.

[0057] The first locking device 225 is configured to be no larger than the width (left and right width) of the vehicle 200, and is equipped with a first locking part 226, which is generally "┓" shaped and is engaged or disengaged from the second locking device 235 described later.

[0058] The third part 230 is the rear part of the vehicle body of the car 200, and is equipped with a second locking device 235.

[0059] like Figure 3 as well as Figure 4 As shown, the second locking device 235 is mounted on the main body 236, which is constructed at a specific distance from the bottom of the lane 100 upwards in order to avoid affecting the driving of the vehicle.

[0060] A specific space for accommodating the second locking device 235 is formed in the main body 236, a portion of which may be located between the two rear wheels 251. In the case described above, it is preferable to form a through hole through which the shaft 237 connecting the two rear wheels 251 can pass.

[0061] That is, the shaft 237 that connects the two rear wheels 251 can be connected through the through hole of the main body 236, so as not to affect the rotation drive of the wheels.

[0062] The second locking device 235 moves via a shaft 237 provided on the main body 236, and is provided at one end with a second locking part 238 that engages or disengages with the first locking part 226 of the first locking device 225, and at the other end with a second magnet 239 that reacts with the first magnet 211 provided on other vehicles.

[0063] The second locking part 238 is securely fixed (locked) to the first locking part 226 when a car traveling behind is not within a certain distance. When a car traveling behind approaches within a certain distance, the lock can be easily released by the reaction of the first magnet 211 and the second magnet 239.

[0064] That is, the second locking part 238 is configured with a specific curved surface to facilitate easy unlocking from the first locking part 226, and the corresponding first locking part 226 is also configured to allow the second locking part 238 to be easily unlocked. Therefore, as... Figure 3 As shown, a curved surface 227 needs to be formed in the first locking part 226.

[0065] like Figure 5 As shown, in addition to the aforementioned configuration, the vehicle 200 may also include a control box C, which controls the vehicle 200's driving, acceleration, and driving status display by receiving control signals transmitted from the remote controller 300.

[0066] In addition, such as Figure 8 As shown, the system may include: a control unit 254, which processes signals from the remote controller 300 to increase the rotational speed of the motor 257 and performs overall control of the car's racing; a receiving unit 255, which receives car start-up signals, light flashing signals, and car acceleration signals transmitted from the remote controller 300 and inputs them to the control unit 254; a power supply unit 256, which, while enabling the control device of the present invention to operate by supplying power, increases the speed of the motor 257 by a specific amount by supplying additional power; the motor 257, which is driven to rotate for driving on the lane 100; a display unit 258, which displays the driving status of the car; and a switch 259, which sets the car driving status displayed by the display unit 258.

[0067] The motor 257 is connected to a plurality of wheels 251 that are driven and rotated in conjunction with the motor 257.

[0068] The motor 257 is driven to rotate at a certain speed according to the signal initially received from the remote controller 300, and when it receives the signal again from the remote controller 300, it increases the speed to rotate and catch up with the vehicle in front.

[0069] The wheel 251 is equipped with the first locking device 225 and the second locking device 235 in a manner that does not affect the driving of the vehicle, and is configured in a size that allows the vehicle body to maintain a certain height from the bottom surface of the lane 100.

[0070] By employing the aforementioned configuration, for example, a specific amount of the first portion 210 of another vehicle traveling behind can be brought under the vehicle traveling in front. That is, by setting the heights of the first portion 210, the second portion 220, and the third portion 230, the first portion 210 can be brought almost into the second portion 220.

[0071] like Figure 6 As shown, the power supply unit 256 is a DC battery, which can basically be composed of two batteries and an LR44 boost battery for acceleration.

[0072] When the second switch 320 equipped on the remote control 300 is pressed for the first time, the two batteries provide driving power to the motor 257 so that the car starts to move. At this time, the car 200 will travel along the lane 100 at a predetermined speed. When the second switch 320 is pressed again, the boost power supply provides acceleration power to the motor 257 so that the car 200 travels along the lane 100 at a specific speed and catches up with the car in front to within a certain distance.

[0073] The signal transmitted from the remote controller 300 can be as follows: Figure 8 The control system shown processes the data, thereby causing the car 200 to start moving.

[0074] When the control unit 254 receives and inputs a signal from the remote controller 300 via the receiving unit 255, it processes the signal and increases the speed of the motor 257, thereby enabling the car 200 to move quickly. That is, the speed can be increased over a certain period. For this purpose, the control unit 254 and the remote controller 300 can be configured to use the same frequency, etc.

[0075] Furthermore, a timer is provided in the control unit 254 to prevent the acceleration signal received from the remote controller 300 from being repeatedly applied within a certain period. That is, it ensures that the speed can only be increased after a certain period has elapsed.

[0076] Remote controller 300 is used to transmit signals to the operating unit of vehicle 200 to drive the vehicle 200 in lane 100, such as... Figure 9As shown, it may include a first switch 310, a second switch 320, a lamp 330, a transmitter 340, and a control unit 350.

[0077] The first switch 310 is used to set the flashing frequency (mode) of the remote control light 330, and is set to be the same as the flashing frequency of the light (display unit) 255 using the switch 259 provided in the vehicle 200. That is, by setting the same number of presses for the first switch 310 and the vehicle's switch 259, the flashing frequency of the remote control light 330 and the control device display unit 258 can be made the same.

[0078] The second switch 320 is used to perform the operation of starting the vehicle 200 to drive and the operation of accelerating the vehicle 200. That is, when the second switch 320 is operated for the first time, the vehicle 200 will start to drive in lane 100, and when operated again, the vehicle 200 will accelerate for a certain period of time.

[0079] The operation described above can be achieved through programs stored in the control unit 254 of the control device and the control unit 350 of the remote controller 300. As described above, even when the second switch 320 is continuously operated, the control unit 254 will not accelerate again for a certain period of time after it is pressed for acceleration; acceleration will only occur when it is operated again after a certain period of time has elapsed.

[0080] Next, please refer to Figure 10 The overall workflow of the car racing system of the present invention, which can also be configured as described above, will be explained. Both cars and racing cars will be used interchangeably.

[0081] First, in step S10, it is determined whether initialization has been completed.

[0082] After initialization is determined to be complete in step S10, step S30 determines whether vehicle driving settings have been completed. The above-described operation can be achieved through methods such as... Figure 8 as well as Figure 9 The configuration shown is implemented as follows. That is, the player operates the first switch 310 equipped on the remote control 300 and the switch 259 equipped on the car 200, thereby making the flashing action of the light 330 on the remote control 300 and the display 258 on the car 200 tend to be consistent.

[0083] If it is determined in step S30 that the vehicle driving settings have not been completed, the process will continue to wait.

[0084] Conversely, when it is determined in step S30 that the car driving settings have been completed, the player operates the second switch 320 of the remote control 300 to transmit the car driving start signal to the control device of the car 200 through the transmitter 340.

[0085] In this way, the control device of the car 200 receives the car driving start signal from the receiving unit 255 and inputs it to the control unit 254, and the control unit 254 controls the motor 257 to rotate at a specific speed, so that the car 200 drives on the lane 100. That is, in step S110, the race car starts racing.

[0086] When the player operates the second switch 320 of the remote control 300 again in the state described above, the operation signal will be transmitted to the control device of the car 200 through the transmitter 340.

[0087] In step S130, when the vehicle's control unit receives a signal transmitted from the remote controller 300 through the receiver 255, the control unit 254 determines that the signal is a vehicle acceleration signal and applies power from the acceleration battery in the power supply unit 256 to the motor 257.

[0088] Next, in step S150, the speed of the motor 257 is increased to a certain speed and the race car will travel on lane 100 and catch up with the race car traveling in front, and the first part 210 enters the second part 220 through the third part 230 of the race car in front.

[0089] Next, the first magnet 211 of the race car traveling behind will act on the second magnet 239 of the race car traveling in front (the second magnet is attracted by the first magnet), thereby unlocking the second locking device 245 from the first locking device 255. That is, in step S170, the second magnet 239 will be attracted by the first magnet 211, thereby causing the second locking device 235 to move and thereby unlocking the second locking part 238 from the first locking part 226.

[0090] Next, as the second locking device 235 of the race car traveling behind releases the first locking device 225 of the race car traveling in front, the first locking device 225 will be released from its state of being elastically engaged to a specific part of the bottom of the car by means of the spring hinge S and unfold to a right angle.

[0091] In step S190, because the first locking device 225 extends to a right angle under the vehicle, the sweeper will lose its center of gravity and detach from the lane 100.

[0092] Next, in step S210, the car race continues.

[0093] [Second Embodiment]

[0094] Figure 11 This is a configuration diagram of a locking device according to a second embodiment of the present invention, and is a schematic diagram illustrating the locked state. Figure 12This is a configuration diagram of a locking device according to a second embodiment of the present invention, and is a schematic diagram illustrating the unlocked state. Figure 13 This is a schematic diagram illustrating the state of the third locking device by means of elastic rotation when the locking device according to the second embodiment of the present invention is unlocked. Figure 14 This is a schematic diagram illustrating a spring component that causes the third locking device to rotate when the locking device according to the second embodiment of the present invention is unlocked.

[0095] The locking device in the second embodiment can be understood as having a similar configuration to that of removing the magnet in the first embodiment.

[0096] The third locking device 500 is provided on the bottom surface of the second part 220 of the vehicle body. When it is locked by the fourth locking device 600 of the other vehicle while it is pressed against the bottom surface of the vehicle body, it will move elastically (rotate) and thereby lift the vehicle body upward and lose its center, thereby causing the vehicle to leave the lane 100.

[0097] That is, such as Figure 14 As shown, to achieve elastic movement, the third locking device 500 can be coupled to a specific part of the bottom surface of the vehicle body via a spring hinge 700. The spring hinge 700 can be considered as... Figure 1 It has the same structure as the spring hinge P in the example.

[0098] When the third locking device 500 is released from its state of being elastically engaged with a specific lower part of the second part 220 by means of the spring hinge 700, the third locking device 500 will unfold to a right angle (rotate) and the vehicle body will be lifted from the lane 100 to a specific height. The vehicle body traveling at a specific speed will lose its center of gravity, tilt, and detach from the lane 100.

[0099] The spring hinge 700 is merely a simple example of a general structure and can be applied without limitation to any component that can elastically connect the first locking device 500 to the bottom surface of the second part 220 and unfold to a specific angle when unlocked.

[0100] For example, on one side of the third locking device 500, i.e. the part equipped with the spring hinge, a general hinge for opening and closing doors is provided. By fixing and attaching a spring component with a specific elasticity at a position adjacent to the hinge, the spring is in a compressed state when the third locking part 520 and the second locking part 620 are engaged with each other. When the third locking part 520 and the fourth locking part 620 are unlocked, the spring can be expanded to a specific angle such as 90° by means of the spring's expansion force, thereby causing the car to rise upward and detach from the lane.

[0101] The third locking device 500 is configured to be no larger than the width (left and right width) of the vehicle 200, and a third locking part 520 with a specific shape is formed in a specific part to engage or disengage with the fourth locking device 600 described later.

[0102] The fourth locking device 600 is provided on the bottom surface of the third part 230 and moves via a shaft 610 provided on the bottom surface of the vehicle body. At one end, it is provided with a fourth locking part 620 that engages or disengages with the third locking part 2226 of the third locking device 500, and at the other end, it is provided with a pressure part 630 that is pressurized by the front end 215 of the first part 210 of the vehicle body.

[0103] The fourth locking device 600 is as follows Figure 12 The shape shown allows the shaft to rotate clockwise around the axis 610 when pressure is applied to the front end 215 of the pressure section 630, thereby allowing the third locking section 520 and the fourth locking section 620 to be easily unlocked. The axis 610 has a similar structure to the axis 237 in the first embodiment, and can be configured such that a component for fixing one end of the axis is provided on a part of the bottom surface of the vehicle body and attached to the component.

[0104] The fourth locking part 620 is securely fixed (locked) to the third locking part 520 under normal conditions, that is, when a car traveling behind is not close to it, but is easily unlocked when the front end 215 of the first part of the car traveling behind applies an impact to the pressure part 630.

[0105] That is, the fourth locking part 620 is configured with a specific curved surface shape so that it can be easily unlocked from the third locking part 520, and the corresponding third locking part 520 can also be formed in a way that allows the fourth locking part 620 to be easily unlocked. For this purpose, the third locking part 520 and the fourth locking part 620 can be formed with the same or similar structure as the first locking part 226, the second locking part 238 and the curved part 227 in the first embodiment.
