DETAILED DESCRIPTION

[0041] In order to make the technical problems solved by the utility model, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the utility model are further described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0042] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0044] The main purpose of the parking guidance device is to display the occupancy status of each parking space in the parking lot in real time and provide accurate parking information to car owners, thereby optimizing the parking experience and improving the efficiency of parking lot use.

[0045] Parking guidance equipment is usually installed above each parking space in the parking lot. It uses a display screen or similar display technology to display the vacancy or occupation status of the parking space in real time. Usually green indicates an empty parking space and red indicates an occupied parking space. In this way, car owners can quickly find an empty parking space, reducing the time and inconvenience of searching for a parking space.

[0046] In actual application scenarios, these guidance devices on top of parking spaces are usually connected to the intelligent management system of the parking lot to ensure the accuracy of the display by updating the parking space information in real time. At the same time, they can also be used in conjunction with other parking facilities (such as self-service payment machines, car search and query terminals, etc.) to provide car owners with a more convenient and intelligent parking experience.

[0047] From the background technology, it can be known that in the relevant technologies of parking lot guidance equipment, parking space indicators can detect and indicate the usage status of parking spaces through devices such as sensors and indicator lights. However, due to the relatively small indication range of current parking space indicators, in some parking lots with relatively large areas, it is difficult for car owners who are far away to observe the indicators, and the indicators fail to play a good indicating role, resulting in car owners still needing to drive their vehicles close to the parking spaces to observe the corresponding indication content, making it impossible to properly guide the parking lot traffic, reducing the parking efficiency of car owners, and easily causing congestion in the parking lot.

[0048] In view of this, the present embodiment provides a parking space status detector, which solves the problem of the small indication range of the above-mentioned detector by enlarging the size of the indication hole for the indicator light to emit, and also enlarges the size of the detection port for the parking space sensor to detect the parking space status, thereby solving a series of technical problems such as low detection accuracy and weak versatility of the detector.

[0049] Please refer to the attached Figure 1-Figure 4 The parking space status detector includes a device body 10, which serves as a supporting base of the detector. Its functions in the detector include but are not limited to the following aspects:

[0050] Carrying and protection: A hollow accommodating cavity (not shown) is formed inside the device body 10 so that the circuit elements of the detector can be loaded into the device body 10, playing the role of carrying and protecting the circuit elements to ensure that the relevant circuit elements can operate stably. It should be understood that the circuit elements include but are not limited to sensors, controllers, display screens, etc.

[0051] Fixing and positioning: A mounting position for mounting on a supporting structure is provided on one side of the device body 10. The device body 10 can be fixed beside or above the parking space through a specific installation method (such as ground mounting, wall mounting, etc.) according to the actual application scenario, thereby ensuring the accuracy and reliability of the parking space status detector.

[0052] Continue with the above content and refer to the attached Figure 2 The device body 10 is provided with a detection port 11 near the front side thereof, the detection port 11 is connected to the accommodating cavity, and the detection port 11 is extended from the front side of the device body 10 to the lower side around the horizontal axis, so that the detection port 11 is provided along the surface of the device body 10, and the opposite ends of the detection port 11 in the extension direction are respectively located near the front side and the lower side of the device body 10, thereby providing sufficient adjustment space for the parking space sensor 30 in the pitch direction of the device body 10;

[0053] The device body 10 is provided with an indication port 12 spaced from the detection port 11 near its rear side, and the indication port 12 extends around the vertical axis so that the indication port 12 is opened along the surface of the device body 10, and its two opposite ends in the extension direction are respectively located near the left and right sides of the device body 10. In actual application scenarios, the indication port 12 is located on the side of the device body 10 away from the corresponding parking space, and is used for the emission of light emitted by the indicator light 40. In this way, by expanding its size in the horizontal direction and increasing its proportion on the device body 10, the light emitting area that can be provided by the device body 10 is widened, the indication range of the detector is widened, and the visibility of the detector is enhanced, so that car owners on both sides of the vehicle aisle and at a long distance can observe the parking space status displayed by it, and car owners can quickly find vacant parking spaces, saving time in finding parking spaces, improving parking efficiency and convenience, and effectively achieving the effect of diverting parking lot traffic, improving the overall utilization efficiency of parking lots, and reducing congestion and delays caused by finding empty parking spaces.

[0054] It should be noted that the definition of the transverse axis described herein is an axis parallel to or nearly parallel to the ground (see Appendix 1). Figure 1-Figure 2 The vertical axis described herein is defined as the axis perpendicular to the ground between the device body 10 and the ground (see attached Figure 1-Figure 2 middle L2).

[0055] The definition of the front and rear sides of the parking space status detector is usually based on the installation position of the device body 10, the usage scenario, and the driver's line of sight. The front side of the device body 10 described in this article is defined as the side of the device body 10 close to the corresponding parking space that needs to be detected. In actual application scenarios, the parking space sensor 30 can detect the status of the corresponding parking space through the detection port 11 opened on the front side of the device body 10; and the rear side of the device body 10 described in this article is defined as the side of the device body 10 opposite to the front side, that is, the side of the device body 10 away from the corresponding parking space. The indication port 12 is opened on the rear side of the device body 10 and extends around the vertical axis, which can ensure that other drivers except those in the front direction of the device body 10 can observe the indication content of the device body 10.

[0056] According to the above embodiment, the parking space status detector further includes a parking space sensor 30 and an indicator light 40, wherein the parking space sensor 30 is arranged in the accommodating cavity and exposed to the outside of the device body 10 through the detection port 11, so as to detect the state of the parking space corresponding to the detector through the detection port 11. The detection port 11 can provide the parking space sensor 30 with an adjustment space in the pitch direction through the above arrangement, so that the parking space sensor 30 can adjust the direction and angle of the parking space sensor 30 according to the relative position of the device body 10 and the corresponding parking space and other conditions, so that the detector can meet different application scenarios and improve the versatility of the detector.

[0057] The indicator light 40 is arranged in the accommodating cavity and is exposed to the outside of the device body 10 through the indicator port 12. The light emitted by the indicator light 40 can be emitted to the outside of the device body 10 through the indicator port 12. The indicator port 12 is not only able to expand the light emission range of the indicator light 40 through the above-mentioned setting, but also allows the device body 10 to carry an indicator light 40 of a larger size, so as to improve the brightness of the indicator light 40 and further increase the visibility of the detector.

[0058] Exemplarily, the parking space sensor 30 for detecting the parking space status includes but is not limited to the following sensor types:

[0059] 1. The infrared sensor 17 detects whether there is a vehicle parked in the corresponding parking space through an infrared transceiver. Its working principle is to project infrared rays to the parking space. When a vehicle enters the parking space, the infrared rays are blocked and a corresponding signal is generated. The signal is sent to the control unit 60 of the detector to control the change of the state of the indicator light 40 through the control unit 60 to remind other car owners that the parking space is occupied.

[0060] 2. Ultrasonic sensors use the time difference when an object reflects ultrasonic waves to measure distance. They can provide accurate measurement data in detecting the arrival and departure of vehicles in parking spaces and the size of the vehicles in the parking spaces. In addition, ultrasonic sensors can also automatically identify the type of vehicles parked in the parking spaces, helping parking space managers to better manage parking space resources.

[0061] In addition, the main function of the indicator light 40 is to display whether there is a vehicle parked in the current parking space so that the driver can quickly find an empty parking space. The indicator usually uses red and green colors to indicate the status of the parking space, red represents that the parking space is occupied, and green represents that the parking space is vacant. In some other embodiments, the indication may also include other colors or flashing modes to provide more detailed information. For example, slow flashing red may indicate that the parking space has been reserved, while fast flashing red may indicate that the parking space is not allowed to be occupied by vehicles.

[0062] The indicator light 40 is usually a high-brightness LED light, which has the characteristics of low light decay, high brightness and strong penetration. The device body 10, as the shell of the detector, can be made of ABS material with good flame retardant properties to ensure that it will not help the fire spread in emergency situations such as fire.

[0063] Please refer to the attached Figure 3 The parking space status detector also includes an adjustment mechanism 20, which is arranged on the top side of the device body 10, and the adjustment mechanism 20 is used to adjust the position of the device body 10 in the height direction and the front-back direction.

[0064] As shown in the figure, the parking space detector has corresponding installation requirements for the distance Y between the device body 10 and the ground and the distance between the device body 10 and the parking space, considering the environmental conditions of the parking lot, the model type of the parking space sensor 30 and other conditions. Figure 3 By setting an adjustment mechanism 20 between the ceiling in the apparatus and the apparatus body 10, the position of the apparatus body 10 can be adjusted accordingly according to the installation requirements during and after the installation of each apparatus body 10, thereby improving the detection accuracy of the detector for the parking space status.

[0065] In one embodiment, the adjustment mechanism 20 includes:

[0066] A fixing rod 21, one end of which is used to be mounted on the ceiling of the garage;

[0067] The telescopic rod 22 is telescopically connected to the other end of the fixed rod 21. When the telescopic rod 22 is connected to the fixed rod 21, the extension directions of the two can be consistent. For example, the fixed rod 21 and the telescopic rod 22 both extend along the vertical axis, so that the movement direction of the telescopic rod 22 relative to the fixed rod 21 is consistent with the direction in which the vertical axis extends, which is used to adjust the distance of the device body 10 from the ground.

[0068] There are many ways to flexibly connect the telescopic rod 22 and the fixed rod 21, including but not limited to flange connection, flange connection, sleeve connection, etc.

[0069] The support component 23 is fixed to the end of the telescopic rod 22 away from the fixed rod 21 and extends in the front-to-back direction to provide a space for the device body 10 to be movably adjusted in the front-to-back direction. The device body 10 can be movably arranged on the support component 23 in the front-to-back direction. By integrating the adjustment structures for adjusting the device body 10 in the up-down direction and the front-to-back direction on the adjustment mechanism 20, the compactness of the adjustment mechanism 20 can be effectively improved, and the space occupied by the adjustment mechanism 20 in the application scenario can be reduced.

[0070] It should be noted that the device body 10 and the supporting component 23 may be connected in the manner of movable connection between the fixing rod 21 and the telescopic rod 22 as exemplified above, but is not limited to the above.

[0071] In addition, in addition to the above-mentioned manual adjustment method between the fixed rod 21 and the telescopic rod 22, and between the support component 23 and the device body 10, an electric control adjustment method can also be used between any two. For example, on the basis of providing a driving device between any two, transmission can be achieved through but not limited to chains, screw pairs, gears and other transmission components, thereby adjusting the relative movement of any two in a preset direction.

[0072] It should be noted that, since the above-mentioned implementation mode is a relatively common technical means in the mechanical field, the specific matching relationship between the fixed rod 21 and the telescopic rod 22, and the specific matching relationship between the supporting component 23 and the device body 10 are no longer described in detail in this implementation mode and the corresponding drawings.

[0073] It is worth mentioning that the adjustment mechanism 20 of this embodiment preferably adopts manual adjustment. The main reason is that after the parking space status detector is installed in place, it is rarely necessary to make a secondary adjustment to the position of the device body 10 in the later stage. Therefore, the manual adjustment method can not only reduce the installation difficulty of the adjustment device, but also effectively reduce the material cost of the mechanism, and correspondingly reduce the overall weight of the device, so that it has a more stable assembly state on the corresponding supporting structure.

[0074] Please continue to refer to the attached Figure 4 In order to further increase the visibility of the parking space status detector, it also includes a guide light board 13, which is rotatably connected to the bottom side of the device body 10 around a vertical axis through a motor 133. Among them, an indication surface is formed on one side of the guide light board 13, and a first indication area 131 and a second indication area 132 surrounding the first indication area 131 are formed on the indication surface.

[0075] In an actual application scenario of the parking space status detector using the above embodiment, the indicating surface of the guide light board 13 can be driven by the motor 133 to rotate between a position facing the corresponding parking space and a position facing the vehicle aisle.

[0076] The motor 133, the guide light board 13, the parking space sensor 30 and the indicator light 40 are all connected to the control unit 60 of the parking space detector. When the parking space sensor 30 detects that the corresponding parking space is in an unoccupied state, the control unit 60 controls the motor 133 to drive the guide light board 13 in the direction of the vehicle aisle according to the signal sent by the parking space sensor 30, and the control unit 60 controls the first indication area 131 to start. Here, the first indication area 131 can be a green light with an arrow pattern to help the owner find the corresponding vacant parking space more easily when approaching the parking space; when the parking space sensor 30 detects that the corresponding parking space is in an unoccupied state, the control unit 60 controls the motor 133 to drive the guide light board 13 in the direction of the vehicle aisle according to the signal sent by the parking space sensor 30. In the occupied state, the control unit 60 controls the motor 133 to drive the guide light sign 13 to face the corresponding parking space according to the signal sent by the parking space sensor 30. In addition, during the vehicle entering the garage, the parking space sensor 30 can collect the position information of the vehicle and compare it with the preset position information, so as to determine whether the parking position of the vehicle is accurate through the control unit 60. At the parking position of the vehicle, the control unit 60 controls the second indication area 132 to start. Here, the second indication area 132 can be green or other colors and have the words "Parked Correctly" to assist the owner in determining whether the parking position of the vehicle meets the garage requirements.

[0077] Please refer to the attached Figure 1-Figure 2 The surface of the device body 10 is an arc surface, so that the device body 10 is roughly a hemispherical structure. On the one hand, such a setting can improve the structural strength of the device body 10 to a certain extent, and on the other hand, it can make the transition of the surface of the device body 10 more natural, so that the edge of the indicator port 12 opened on the surface of the device body 10 is an arc structure, which expands the light output angle of the indicator light 40 and achieves the purpose of improving visibility.

[0078] On the basis of the above embodiment, the indicator port 12 is also covered with an arc-shaped lampshade 15, and the surface of the arc-shaped lampshade 15 is connected with the surface of the device body 10 to ensure the aesthetics of the detector. It also allows the light emitted by the indicator light 40 to be refracted at a larger exit angle, which helps to scatter the light more widely, improve the visibility of the detector, and make it easier for users to identify vacant parking spaces.

[0079] On the basis of the above embodiment, a mounting surface 14 tilted backward from top to bottom is formed on the front side of the device body 10, a mounting portion 141 for accommodating the parking space sensor 30 is convexly provided in the middle of the mounting surface 14, and the detection port 11 is provided in the mounting portion 141. The mounting surface 14 is provided with heat dissipation ports 142 communicating with the accommodating cavity on the left and right sides of the mounting portion 141, and a heat dissipation fan 50 is provided in the accommodating cavity at the heat dissipation ports 142.

[0080] The relatively flat mounting surface 14 can provide a corresponding mounting position for the cooling fan 50, avoiding the influence of the arc surface structure on the mounting of the cooling fan 50. The cooling fan 50 can discharge the air in the receiving cavity, or draw the external air into the receiving cavity. Of course, it can also be configured so that a part of the cooling fan 50 discharges the air in the receiving cavity, and another part of the cooling fan 50 draws the air into the receiving cavity. The mounting portion 141 protruding from the mounting surface 14 can provide a normal installation space for the parking sensor 30. In this embodiment, the parking sensor 30 can be rotatably connected to the side wall of the mounting portion 141 through a rotating shaft, so that the pitch angle can be adjusted by rotating the rotating shaft. The surface of the mounting portion 141 used to open the detection port 11 is the same as the surface of the device body 10 used to open the indication port 12, and also adopts an arc surface structure. The center of the arc surface of the mounting portion 141 is as close to the rotation axis of the parking sensor 30 as possible, thereby ensuring as much as possible that the distance between the sensor head and the detection port 11 is consistent during the pitch angle adjustment process of the parking sensor 30, thereby avoiding the cover plate covering the detection port 11 from affecting the detection accuracy.

[0081] In one embodiment, if Figure 4 As shown, support rods 16 extending in opposite directions are respectively provided on the left and right sides of the device body 10 , and the support rods 16 can provide corresponding accommodation space and installation positions for other components in the detector.

[0082] Specifically, parking sensors 161 are provided on both support rods 16. In actual application scenarios, the parking sensors 161 can be used to collect position information of the above-mentioned vehicle during the storage process. The parking sensor 161 is activated when the parking space sensor 30 detects that a vehicle has entered the parking space, and is used to collect the position information of the vehicle entering the parking space. By comparing the preset parking position with the vehicle position information, it is determined whether the parking position of the vehicle is correct.

[0083] The parking sensors 161 arranged on the support rods 16 on both sides are used to collect the vehicle's position information. Based on the connection between the parking sensors 161 and the control unit 60 of the detector, the accuracy of the detector in collecting the vehicle's position information can be improved. Taking the combination of two parking sensors 161 to form a binocular camera as an example, the binocular camera uses two cameras to simultaneously shoot the same scene (the same parking space) and calculate the parallax between the two images, thereby realizing accurate perception of the object's depth information. This high-precision depth information enables the system to accurately determine whether the vehicle is parked in the correct position, avoiding misjudgment caused by position error.

[0084] In addition, lighting lamps 162 are disposed on both support rods 16 , and the lighting lamps 162 are disposed in a direction away from the device body 10 . When the lighting lamps 162 are turned on, the lighting lamps 162 can provide lighting for the vehicle aisle corresponding to the detector.

[0085] In one embodiment, in an implementation using the illuminating lamp 162 as the lighting device for the vehicle passage, the illuminating lamp 162 is always on, so that the illuminating lamps 162 on multiple detectors can be connected to each other to illuminate the entire vehicle passage;

[0086] In another embodiment, the lighting 162 can also serve to further indicate the status of the parking space. For example, when the parking space is determined to be unoccupied, the control unit 60 of the detector controls the lighting 162 to start up based on the connection with the lighting 162, so that the driver can know the specific location of the vacant parking space more clearly.

[0087] In one embodiment, the parking space sensor 30 is specifically an ultrasonic sensor. As a sensor for detecting the parking space status, the ultrasonic sensor has the following advantages compared with other sensors:

[0088] 1. High precision and accuracy. Ultrasonic signals can accurately measure distances, so ultrasonic sensors can provide high measurement precision and accuracy to ensure accurate judgment of whether a parking space is occupied;

[0089] 2. Fast response speed: Ultrasonic sensors have a fast response speed and can quickly detect changes in parking spaces. This makes ultrasonic sensors perform well in real-time parking space detection systems, and can update parking space status in a timely manner, providing real-time data support for parking lot management.

[0090] 3. Strong anti-interference ability: Ultrasonic sensors have good anti-interference ability against interference factors such as ambient temperature, humidity and noise.

[0091] 4. Low installation and maintenance costs: Ultrasonic sensors have a simple structure, are easy to install, and have low maintenance costs. This makes the application of ultrasonic sensors in places such as parking lots highly economical and reduces overall operating costs.

[0092] 5. Strong adaptability: Ultrasonic sensors are insensitive to the material of the surface of the object being measured and can adapt to parking spaces and vehicle surfaces of different materials. At the same time, they can also adapt to different measurement ranges and distances to meet the needs of various application scenarios.

[0093] Furthermore, an infrared sensor 17 is also disposed at the bottom of the device body 10 .

[0094] The infrared sensor 17 can cooperate with the ultrasonic sensor to detect the corresponding parking space status. For example, when the detection area of ​​the infrared sensor 17 is the vehicle channel corresponding to the fleet, the infrared sensor 17 can first detect the presence of the vehicle, so that the control unit 60 can wake up the corresponding device in advance, so that the subsequent control can respond in time;

[0095] In the case where the detector is provided with a guide light board 13 , the infrared sensor 17 is provided at the bottom of the guide light board 13 .

[0097] In the case where the adjustment mechanism 20 is disposed on the top side of the device body 10 , the device body 10 is mounted on the adjustment mechanism 20 via the mounting base 70 .

[0098] Furthermore, an opening is provided on one side of the device body 10 for placing each circuit element into the receiving cavity, and the mounting base 70 is covered at the opening. A threading hole 71 connected to the receiving cavity is penetrated through the middle of the mounting base 70, so that the wires of the circuit elements located in the receiving cavity can pass through the threading hole to achieve connection with an external power supply and a control terminal.

[0099] In addition, the mounting base 70 is also penetrated by a plurality of mounting holes 72 arranged at intervals around the threading holes 71 , and each mounting hole 72 is a waist-shaped hole.

[0100] Attach Figure 5Taking the example of setting waist-shaped holes on the front and back and left and right sides of the mounting base 70, the directions in which the two opposite waist-shaped holes on the left and right extend are parallel to each other, while the directions in which the two opposite waist-shaped holes on the front and back extend are parallel to each other, and the directions in which the left and right waist-shaped holes and the front and back waist-shaped holes extend are perpendicular to each other, so as to reduce the difficulty of installing the detector.

[0101] Please refer to the attached Figure 6 In summary, the detector of this embodiment is connected to the parking space sensor 30, the indicator light 40, the guide light sign 13, the motor 133, the cooling fan 50, the parking sensor 161, the lighting lamp 162 and the infrared sensor 17 through the control unit 60, and the control logic provided by the above embodiment is used to achieve the effect of improving the visibility of the detector, thereby greatly improving the guidance efficiency of the parking lot.
