Description

Technology Field

[0001] The present invention relates to a parking stopper that prevents damage caused by a vehicle and allows visual confirmation of the contact state. More specifically, the invention relates to a parking stopper that prevents damage caused by contact with a wheel and allows the driver to visually confirm the position of the stopper and stop the vehicle before contact, thereby preventing damage caused by a vehicle and allowing visual confirmation of the contact state. Background Technology

[0002] Generally, parking lots in parking garages and large buildings establish parking lines to ensure safe parking, and parking stoppers are fixed to the floor behind the lines as a supplementary measure to prevent vehicles from veering out of the designated spaces.

[0003] A parking stopper installed at the edge of a parking area to prevent a vehicle from moving out of the parking area when parking has a function intended to provide convenience for parking by allowing the vehicle to feel the sensation of hitting the parking stopper as it moves slowly forward or backward in the partitioned parking lot without accurate distance measurement.

[0004] Conventional parking stoppers are made of rubber or synthetic resin, and to secure the parking stopper for vehicle parking, multiple anchor bolts are fixed to the ground and the parking stopper is fastened to the anchor bolts with fastening nuts; however, the parking stopper is composed of a rectangular prism with a trapezoidal cross-section.

[0005] However, with the parking stopper described above, the driver senses whether they have reached the parking stopper due to the impact or vibration generated by contact with the vehicle's wheels, and this contact applies a load to the main body of the parking stopper.

[0006] Therefore, as time passes, the parking stopper is gradually subjected to load and impact by vehicles, causing damage to the outer surface of the parking stopper. Since it is impossible to partially separate only the damaged part, the entire damaged parking stopper must be replaced, resulting in continuous costs.

[0007] In addition, there was a problem where, if the parking stopper was damaged, the anchor embedded in the ground was exposed, and the vehicle was damaged as the wheel came into contact with the exposed anchor. Prior art literature

[0009] The objective of the present invention to solve the above-mentioned problems is to provide a parking stopper that allows the driver to stop the vehicle before the wheel contacts the main body of the parking stopper fixed to the ground, thereby preventing damage caused by the vehicle and allowing the driver to visually check the contact state.

[0010] In addition, another objective of the present invention is to provide a parking stopper that has a replaceable pad formed on the parking stopper protruding outwardly to absorb and disperse the impact of a parked vehicle, prevent damage to the parking stopper, and allow visual confirmation of the contact state.

[0011] In addition, another objective of the present invention is to provide a parking stopper that prevents damage caused by a vehicle and allows visual confirmation of the contact status, wherein visual information is output from the parking stopper according to the vehicle's entry state, enabling the driver to check the gap between the vehicle's wheels and the parking stopper. means of solving the problem

[0012] The parking stopper of the present invention, which prevents damage by a vehicle and allows visual confirmation of the contact state to solve the above problem, is characterized by comprising: a housing formed to be fixed to the ground with an anchor and having a detachment prevention groove on the front; a shock absorption part formed to be inserted into and fixed to the detachment prevention groove and absorbing shock transmitted to the housing by contacting the wheel of a parked vehicle; a lighting part formed on the outer surface of the housing and emitting light according to the approach state of the vehicle so that the driver can recognize it; and a sensor part formed on the outer surface of the housing and controlling the lighting part by detecting the approach state of the vehicle and the contact state of the wheel.

[0013] In addition, the shock-absorbing portion of the parking stopper of the present invention, which prevents damage by a vehicle and allows visual confirmation of the contact state, is formed of a flexible material and is characterized by comprising a contact pad, one end of which protrudes toward the front of the housing and absorbs shock by being compressed when the wheel comes into contact, and a dispersion pad having a honeycomb structure that supports the other end of the contact pad inside the anti-detachment groove and disperses the shock transmitted from the contact pad.

[0014] In addition, the shock absorbing part of the parking stopper of the present invention, which prevents damage by a vehicle and allows visual confirmation of the contact state, is characterized by further including a shape-restoring member formed at regular intervals inside, wherein the member is restored to its original shape when compression deformation or shape deformation occurs due to contact with the wheel.

[0015] In addition, the lighting unit of the parking stopper of the present invention, which prevents damage by a vehicle and allows visual confirmation of the contact state, is characterized by including a plurality of LEDs formed on the outer surface of the housing, which output different lights depending on the distance the wheel approaches the housing so that the driver can recognize them.

[0016] In addition, the lighting unit of the parking stopper of the present invention, which prevents damage by a vehicle and allows visual confirmation of the contact state, is characterized by including a laser module that outputs a guideline to guide a stopping position to the side of the housing using a laser and changes the color of the boundary line according to the distance the wheel approaches the housing.

Effects of the invention

[0018] As described above, according to the present invention, a parking stopper that prevents damage by a vehicle and allows visual confirmation of the contact state can be confirmed when a vehicle enters a parking space, thereby enabling the driver to stop the vehicle before the wheel contacts the main body of the parking stopper fixed to the ground.

[0019] In addition, according to the parking stopper of the present invention, which prevents damage caused by a vehicle and allows visual confirmation of the contact state, a pad formed to be replaceable on the parking stopper protrudes outwardly, thereby absorbing and dispersing the impact of a parked vehicle and preventing damage to the parking stopper.

Specific details for implementing the invention

[0022] The specific features and advantages of the present invention will be described in detail below with reference to the accompanying drawings. Prior to this, if it is determined that a detailed description of the functions and configurations related to the present invention may unnecessarily obscure the essence of the invention, such detailed description will be omitted.

[0023] The present invention relates to a parking stopper that prevents damage caused by a vehicle and allows visual confirmation of the contact state. More specifically, the invention relates to a parking stopper that prevents damage caused by contact with a wheel and allows the driver to visually confirm the position of the stopper and stop the vehicle before contact, thereby preventing damage caused by a vehicle and allowing visual confirmation of the contact state.

[0024] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0025] FIG. 1 is a configuration diagram showing the structure of a parking stopper that can visually confirm the contact state and prevent damage caused by a vehicle according to the present invention; FIG. 2 is an example diagram showing the use of a parking stopper that can visually confirm the contact state and prevent damage caused by a vehicle according to the present invention; FIG. 3 is a perspective view showing the exterior of a parking stopper that can visually confirm the contact state and prevent damage caused by a vehicle according to the present invention; and FIG. 4 is an exploded view showing the internal structure of a parking stopper that can visually confirm the contact state and prevent damage caused by a vehicle according to the present invention.

[0026] As illustrated in FIGS. 1 to 4, the parking stopper according to the present invention, which can visually confirm the contact state and prevent damage caused by a vehicle (C), is characterized by comprising: a housing (100) formed to be fixed to the ground with an anchor and having a detachment prevention groove (110) provided on the front; a shock absorption part (300) formed to be inserted into and fixed to the detachment prevention groove (110) and absorbing shock transmitted to the housing (100) by contacting the wheel of the parked vehicle (C); a lighting part (200) formed on the outer surface of the housing (100) and emitting light according to the approach state of the vehicle (C) so that the driver can recognize it; and a sensor part (400) formed on the outer surface of the housing (100) and controlling the lighting part (200) by detecting the approach state of the vehicle (C) and the contact state of the wheel.

[0027] Additionally, it is characterized by further including a cover (500) formed on the outer surface of the housing (100) to allow the shock absorbing part (300), the lighting part (200), and the sensor part (400) to be exposed to the outside, and to close both sides of the anti-detachment groove (110) formed in the housing (100) to prevent the shock absorbing part (300) from detaching.

[0028] The housing (100) is formed inside a marked parking space where a vehicle (C) can be parked, and the upper surface of the housing (100) has a plurality of fixing holes formed at regular intervals so that a plurality of anchors can be inserted.

[0029] The anchor can be fixed to the housing (100) while being inserted into a fixed hole (not shown) and driven into the ground, and the fixed hole into which the anchor is inserted can be configured so as not to be exposed to the outside by a separate cap (not shown).

[0030] In addition, a drainage channel is formed in the fixed hole to discharge water toward the bottom or outer surface of the housing (100), and if rainwater flows in between the caps, the rainwater is discharged through the drainage channel, thereby preventing the anchor from rusting.

[0031] At this time, it is preferable that the fixing holes be formed on both edges of the upper surface of the housing (100), avoiding the LED (210) formed in the lighting unit (200).

[0032] The housing (100) is provided with a detachment prevention groove (110) formed to allow the shock absorber (300) to be mounted or detached, and the detachment prevention groove (110) opens the front of the housing (100) so that when the shock absorber (300) is mounted on the housing (100), one end of the shock absorber (300) can protrude toward the front of the housing (100).

[0033] The anti-detachment groove (110) is formed inwardly from the front of the housing (100) and extends from one side of the front of the housing (100) to the other side, so that when the housing (100) is viewed from the side, the anti-detachment groove (110) has a shape that is penetrated.

[0034] At this time, the anti-detachment groove (110) is configured such that a height difference occurs by forming protruding ends (111) that protrude outwardly at the upper and lower front sides of the housing (100), respectively, and when the shock absorbing part (300) is inserted into the anti-detachment groove (110), it can be prevented from moving in the front direction by the protruding ends (111).

[0035] Therefore, in order to mount or detach the shock absorber (300) in the anti-detachment groove (110), it is preferable to insert and slide the shock absorber (300) from the side direction of the housing (100), and the shock absorber (300) inserted in the anti-detachment groove (110) is prevented from moving in the front direction of the housing (100) and can absorb shock by being compressed or restored by contact with the wheel.

[0036] The shock absorber (300) is protruded from the front of the housing (100) and is used to prevent the outer surface of the housing (100) from coming into direct contact with the wheel when the vehicle (C) moves toward the housing (100) for parking, and to reduce the load and external force caused by impact transmitted to the housing (100) by the wheel, thereby preventing the housing (100) from being damaged.

[0037] At this time, when the shock absorber (300) is compressed and damaged by the wheel, it can be separated from the housing (100) through the anti-detachment groove (110) and replaced. Compared to the housing (100) which must be fixed to the ground with an anchor when replaced, it has the advantage of being easier to install and cheaper to replace.

[0038] The lighting unit (200) is used to emit light from the housing (100) so that the driver can recognize when the vehicle (C) approaches, and outputs the state where the vehicle (C) is not in the parking space, the state where the vehicle (C) is attempting to park in the parking space, and the state where the vehicle (C) is parked in the parking space in different colors.

[0039] The driver can visually confirm the position of the housing (100) according to the color emitted by the lighting unit (200), and can complete parking without contacting the housing (100) by the lighting unit (200).

[0040] The sensor unit (400) is formed in the housing (100) and is used to detect the approach state of the vehicle (C) and the contact state of the wheel, and the lighting unit (200) is formed so that the color can be varied by being controlled by the operation of the sensor unit (400).

[0041] Additionally, the housing (100) may be configured to have a battery (120) formed inside to supply power for the operation of the lighting unit (200) and the sensor unit (400), and to charge the battery (120) through self-generation using a solar panel (130).

[0042] Depending on the needs, the housing (100) may be formed to receive external power, and if external power supply is possible, it may be used without a battery (120) installed inside, and if a battery (120) is installed, it may be configured to be used in an emergency when the external power is cut off.

[0043] The cover (500) is used to cover the outer surface of the housing (100) to prevent external impact or contamination, and to prevent the shock absorbing part (300) inserted into the anti-detachment groove (110) from being separated from the housing (100).

[0044] At this time, it is preferable that the cover (500) be open so that the location where the shock absorber (300), lighting unit (200), sensor unit (400), and solar panel (130) are formed is exposed to the outside, and the cover (500) must be able to wrap around both sides of the housing (100) and secure the shock absorber (300) which is inserted from the side and mounted or detached.

[0045] When the cover (500) surrounds and protects the housing (100), the shock absorber (300) is prevented from moving to either side of the housing (100) by the cover (500), and a third party cannot arbitrarily separate the shock absorber (300) by the cover (500).

[0046] In addition, it is preferable that a locking device, such as a lock, be formed on the rear surface of the housing (100) to prevent the cover (500) attached to the outer surface from being arbitrarily separated, and the cover (500) can be prevented from being arbitrarily separated through the locking device.

[0047] Additionally, the shock absorbing part (300) is formed of a flexible material and is characterized by comprising a contact pad (310) that is formed and protrudes from the front of the housing (100) and absorbs shock by being compressed when a wheel comes into contact, and a dispersion pad (320) that has a honeycomb structure, supports the other end of the contact pad (310) inside the anti-detachment groove (110), and disperses the shock transmitted from the contact pad (310).

[0048] The contact pad (310) is used to absorb shock transmitted from the wheel by making prior contact with the wheel of a vehicle (C) moving for parking while protruding from the front of the housing (100), and to prevent the wheel from directly contacting the housing (100).

[0049] The contact pad (310) is formed so that it protrudes toward the front of the housing (100) at one end to come into contact with the wheel, and the other end is formed so that it can be inserted into and fixed in the anti-detachment groove (110) formed in the housing (100).

[0050] At this time, the thickness of one end of the contact pad (310) is formed to be smaller than that of the other end, so that the cross-section of the contact pad (310) is formed in a T-shape, and one end of the contact pad (310) is positioned between the protruding ends (111) and can protrude to the front outside of the housing (100).

[0051] In addition, the other end, which is formed to be thicker than the first end of the contact pad (310), is positioned inside the anti-detachment groove (110) and is in a state where it cannot move toward the front of the housing (100) by means of the protruding end (111).

[0052] At this time, the other end of the contact pad (310) is supported by a protruding end (111) formed in the anti-detachment groove (110), so that the contact pad (310) can be prevented from moving toward the front direction of the housing (100).

[0053] In addition, the upper part of the contact pad (310) has a slope formed thereon to prevent the corner from being worn or damaged by the wheel when the wheel comes into contact, and to increase the contact area with the wheel so that the outer surface of the wheel remains in stable contact.

[0054] The dispersion pad (320) is formed at the other end of the contact pad (310) and is used to prevent stress concentration by dispersing the impact and load transmitted through the contact pad (310) on the inner side of the anti-detachment groove (110).

[0055] The dispersion pad (320) is formed in a plate shape and can maintain contact with the other end of the contact pad (310) and the inner surface of the anti-detachment groove (110). When the contact pad (310) absorbs the impact in the first stage while being compressed, the dispersion pad (320) is compressed in the second stage and disperses the impact to the housing (100).

[0056] In order for the dispersion pad (320) to effectively disperse the impact transmitted from the contact pad (310), it is preferable that the dispersion pad (320) have a hexagonal honeycomb pattern, and honeycomb grooves or honeycomb ribs are formed at regular intervals on both one side and the other side of the dispersion pad (320).

[0057] The honeycomb structure can absorb up to 80% of the impact energy received by an object during a head-on collision, and since cushioning can also be applied, stable impact absorption can be expected.

[0058] The contact pad (310) and the dispersion pad (320) are formed of a synthetic resin material capable of absorbing shock by compression. The contact pad (310) is formed of a material with high elasticity so that it can absorb shock by being compressed by the wheel, and the dispersion pad (320) is formed of a material with lower elasticity than the contact pad (310).

[0059] The contact pad (310) has high elasticity and can absorb shock by being compressed by the load of the vehicle (C) when the wheel contacts it, and the dispersion pad (320) can disperse the transmitted shock into the housing (100) while being compressed relatively less than the contact pad (310).

[0060] Additionally, the shock absorbing member (300) is characterized by further including a shape-restoring member (330) formed at regular intervals inside, which restores the original shape when a wheel comes into contact and causes compression deformation or shape deformation.

[0061] When the contact pad (310) comes into contact with the wheel, its shape changes downward along the rotational direction of the wheel, and as the wheel moves toward the housing (100), the contact pad (310) is compressed to absorb the shock.

[0062] The contact pad (310) has its own elasticity, so even if compression deformation or shape deformation occurs due to the wheel, the contact pad (310) can be restored to its original shape when the vehicle (C) moves and the external force applied by the wheel is removed.

[0063] However, if deformation occurs beyond the elastic limit of the contact pad (310), it remains in a deformed state and the elasticity of the contact pad (310) itself may be reduced overall, so it cannot properly absorb the shock generated when in contact with the wheel.

[0064] In severe cases, one end of the contact pad (310) may break, causing the wheel to come into direct contact with the front of the housing (100), which may cause damage to the housing (100).

[0065] In order for the contact pad (310) to have stable elasticity, a shape-restoring member (330) is formed inside the contact pad (310), and the shape-restoring member (330) can support one end of the contact pad (310) when the contact pad (310) is compressed or its shape is deformed.

[0066] The shape restoration member (330) is formed as a coil spring so that when one end of the contact pad (310) is compressed by a wheel, the internal coil spring is also compressed, and when one end of the contact pad (310) is bent downward, the internal coil spring is also bent.

[0067] Through this, the coil spring, which is deformed in the same way as the compression or shape deformation of the contact pad (310) by the force of the wheel, is restored to its original state when the external force is removed, thereby restoring the contact pad (310), so that the contact pad (310) can be restored to its original state even with more compression or deformation.

[0068] It is preferable that a plurality of shape restoration members (330) are formed at regular intervals inside the contact pad (310), and if necessary, the contact pad (310) and the shape restoration members (330) may be formed in a physically separated state.

[0069] When the contact pad (310) and the shape restoration member (330) are physically separated, only the contact pad (310) damaged by the external force of the wheel can be replaced and used, thereby improving productivity and reducing replacement costs.

[0070] To this end, an opening is provided at the center of the other end of the contact pad (310) so that a shape-restoring member (330) can be inserted, and the shape-restoring member (330) can be formed at regular intervals on the outer surface of the dispersion pad (320) and configured so that the shape-restoring member (330) is inserted into the opening when the contact pad (310) and the dispersion pad (320) are combined.

[0071] Additionally, the lighting unit (200) is characterized by including a plurality of LEDs (210) formed on the outer surface of the housing (100) to output different lights depending on the distance the wheel approaches the housing (100) so that the driver can recognize them.

[0072] The lighting unit (200) is used to provide visual information so that when a driver attempts to park, the wheels can be seen close to the housing (100) to check if the parking is being done using light.

[0073] At this time, the lighting unit (200) uses a plurality of LEDs (210) formed on the outer surface of the housing (100) to output light of different colors depending on the state in which the vehicle (C) attempts to park, thereby enabling the driver to determine the parking state through the color of the light.

[0074] As shown in FIG. 3, the LED (210) is depicted as being located on the upper surface of the housing (100), but it is preferable that the LED (210) also be formed on the side of the housing (100) so that when the vehicle (C) is parked and the housing (100) is located on the lower part of the vehicle (C), the driver can see the light emitted from the side of the housing (100).

[0075] The LED (210) outputs different colors when there is no vehicle (C) in the parking space, when the vehicle (C) attempts to park in the parking space, and when the vehicle (C) is parked in the parking space.

[0076] When there is no vehicle (C) in the parking space, the LED (210) formed on the upper surface of the housing (100) is formed to emit a green light, and when a vehicle (C) is parked in the parking space, it is formed to emit a red light.

[0077] The user can check from a distance whether there is a parking area through the green light of the LED (210) emitting from the outer surface of the housing (100), and can recognize that a vehicle (C) is present in the parking area through the red light.

[0078] When a driver enters the parking space and attempts to park, the lighting unit (200) recognizes the state in which the vehicle (C) attempts to park by means of the sensor unit (400), and outputs the color of the LED (210) by gradually varying it from orange to red according to the distance from the wheel, thereby allowing the driver to recognize the distance from the housing (100) through the color.

[0079] When a driver attempts to park by bringing the vehicle (C) into the parking space, the sensor unit (400) formed in the housing (100) detects the wheel formed on the vehicle (C), recognizes that parking is being attempted, and outputs an orange light.

[0080] At this time, the driver can check the color of the light of the LED (210) formed on the upper surface or side of the housing (100) through the rear camera or side mirror.

[0081] When the wheel moves slowly toward the front of the housing (100), the sensor unit (400) measures the distance to the wheel of the vehicle (C) moving toward the housing (100) and can control the color output from the lighting unit (200) to vary.

[0082] At this time, the sensor unit (400) can detect the wheels of the vehicle (C) at a distance of at least 1 meter to a maximum of 3 meters, and when the detection distance is less than 1 meter, the recognition is improved because the wheels are aligned, but because the distance is short, it is difficult for the driver to adjust the distance by looking at the color of the LED (210).

[0083] If the distance exceeds 3 meters, the bumper or frame of the vehicle body is recognized first before the wheels are aligned, so the color of the LED (210) changes even while the vehicle (C) is moving to align the wheels to the housing (100), which can confuse the driver.

[0084] Therefore, it is desirable to set the detection distance of the sensor unit (400) to be 1 meter or more and less than 3 meters, and when the wheel approaches the distance, the LED (210) outputs an orange color.

[0085] The driver can gradually enter while checking the color of the output LED (210) through the rear camera or side mirror, and when the wheel contacts the contact pad (310), the color of the LED (210) is output as red.

[0086] At this time, it is desirable that the LED (210) gradually change color from orange to red depending on the distance the wheel approaches, and when the wheel comes into contact with the contact pad (310), the LED (210) flashes to warn the driver not to reverse.

[0087] When the parking of the vehicle (C) is completed and the sensor unit (400) recognizes that the position of the wheel is at the same distance for a certain period of time, the LED (210) can stop flashing and remain in a state where it is lit in red.

[0088] Additionally, as needed, a speaker is formed inside the housing (100) to output an alert sound along with an LED (210) according to the distance the wheel of the vehicle (C) approaches, thereby providing auditory information and preventing the wheel from coming into contact with the housing (100).

[0089] Additionally, the lighting unit (200) is characterized by including a laser module (220) that outputs a guideline to guide a stop position to the side of the housing (100) and changes the color of the boundary line according to the distance the wheel approaches the housing (100).

[0090] The laser module (220) is formed on the side of the housing (100) and is used to emit a laser at the edge of the parking space line to output distance information required when the vehicle (C) is parked.

[0091] At this time, the laser module (220) outputs a guideline around the parking space line using a laser, with the state in which the wheel is in contact with the contact pad (310) by the sensor unit (400) as a reference point, including the distance value between the wheel and the contact pad (310), the location where the contact pad (310) is formed, and the location of the wheel.

[0092] The guideline indicates the location where the contact pad (310) is formed with a red line, the position of the wheel of the entering vehicle (C) with a blue line, and the distance value is formed to gradually vary from orange to red depending on the distance between the wheel and the contact pad (310).

[0093] At this time, the distance value is displayed in red when the contact pad (310) and the wheel are in contact, and in orange when the sensor unit (400) can recognize the wheel at the initial position.

[0094] Additionally, the laser module (220) can output text to indicate entry, slowing down, and stopping on the floor, and the sensor unit (400) can indicate entry when the distance between the wheel and the contact pad (310) is 2 meters or more, slowing down when the distance between the wheel and the contact pad (310) is within 1 meter, and stopping when the distance between the wheel and the contact pad (310) is 10 centimeters.

[0095] In addition, the wheel position formed in the guideline moves toward the position where the contact pad (310) is formed as the vehicle (C) moves, allowing the user to move the vehicle (C) only to the position where the wheel contacts the contact pad (310) based on the information formed on the floor through the side mirror.

[0096] Additionally, the sensor unit (400) is characterized by including a sensing sensor (410) formed on the front of the housing (100) to detect the position and distance of the wheel, and a load cell (420) formed inside the anti-detachment groove (110) to detect the load transmitted by the shock absorbing unit (300) and determine the contact state of the wheel.

[0097] A detection sensor (410) is formed on the front of the housing (100) and is used to detect the wheels of the vehicle (C), measure the distance between the wheels and the contact pad (310), and calculate distance information.

[0098] The detection sensor (410) can use a laser or ultrasonic wave, and can measure the distance from the contact pad (310) to the wheel in real time with one end of the contact pad (310) as the origin, thereby allowing the color of the lighting unit (200) to be varied according to the distance value.

[0099] In the case of the detection sensor (410), since malfunction may occur due to external foreign matter, a load cell (420) for determining the contact state of the wheel is formed inside the anti-detachment groove (110) so that the contact state with the contact pad (310) can be checked more accurately.

[0100] A load cell (420) is used to determine whether the wheel is in contact with the contact pad (310) by measuring the load or strain that occurs when the contact pad (310) is compressed or deformed while in contact with the wheel.

[0101] When the wheel is in contact with one end of the contact pad (310), an electrical signal is generated by the load cell (420), and the lighting unit (200) changes the color of the light emitted by the load cell (420) so that the driver can be induced to stop the vehicle (C).

[0102] Additionally, it is preferable that multiple load cells (420) be distributed within the anti-detachment groove (110) to check the load or strain at the location where the wheel contacts.

[0103] In addition, a communication module is built into the housing (100) so that the damage to the housing (100) can be checked remotely, and when the load or strain measured by the load cell (420) is at a level where the impact applied to the housing (100) causes damage, the communication module can wirelessly transmit the impact information to the parking manager's smartphone.

[0104] Therefore, the parking attendant may warn the driver of the parked vehicle (C) or claim damages for the damaged housing (100).

[0105] FIGS. 5 to 7 are exemplary diagrams showing a deformed state of the shock-absorbing part (300) of a parking stopper that can visually confirm the prevention of damage and contact state caused by a vehicle (C) according to the present invention.

[0106] As illustrated in FIGS. 5 to 7, the shape of the contact pad (310) of the parking stopper, which prevents damage by the vehicle (C) according to the present invention and allows visual confirmation of the contact state, can be formed in an arc shape rather than an inclined surface.

[0107] As shown in Fig. 5, when one end of the contact pad (310) is formed in a circular shape, the corner can be prevented from being damaged or worn out by friction of the wheel due to the arc shape when a rotating wheel enters.

[0108] As shown in FIG. 6, the thickness of one end of the contact pad (310) is formed to be the same as the thickness of the other end, and the thickness of the middle portion fixed by the protruding end (111) is formed thinly, so that the impact generated when a wheel contacts the contact pad (310) can be dispersed and transmitted to the one end and the other end, respectively.

[0109] That is, one end of the contact pad (310) is in contact with the front surface of the housing (100) to absorb and disperse the impact, and the other end is able to absorb and disperse the impact through the anti-detachment groove (110) inside the housing (100).

[0110] As shown in FIG. 7, the inner surface of the anti-detachment groove (110) of the housing (100) can be formed in a circular shape, and the shape of the dispersion pad (320) can also be formed in a circular shape, thereby increasing the contact area between the housing (100) and the dispersion pad (320).

[0111] As the contact area of ​​the dispersion pad (320) with the housing (100) increases, the impact transmitted from the contact pad (310) can be spread and dispersed over a wide area where the dispersion pad (320) is in contact, thereby preventing the concentration of stress in one area due to the impact applied inside the housing (100).

[0112] As described above, according to the present invention, a parking stopper capable of preventing damage by a vehicle and visually confirming the contact state allows the driver to stop the vehicle before the wheels come into contact with the main body of the parking stopper fixed to the ground by confirming the state of approaching the parking stopper when the vehicle enters the parking space line. Additionally, a pad formed to be replaceable on the parking stopper protrudes outwardly, which absorbs and disperses the impact of the parked vehicle and prevents damage to the parking stopper. Furthermore, visual information is output from the parking stopper according to the vehicle's entry state, allowing the driver to check the distance between the vehicle's wheels and the parking stopper.

[0113] As described above, although the present invention has been explained with reference to preferred embodiments, those skilled in the art may implement the present invention with various modifications or variations without departing from the technical spirit and scope described in the claims of the present invention. Accordingly, the scope of the present invention should be interpreted by the claims described to include such many variations. Explanation of the symbols
