Description

Technical Field

[0001] This application relates to the field of intelligent parking management, and in particular to a parking space detector. Background Technology

[0002] In the field of intelligent parking management, parking space detectors are key devices for real-time monitoring of parking space status. Their ease of installation, operational stability, and detection accuracy directly affect management efficiency. However, existing parking space detectors have several limitations in practical applications: First, the installation process is complex, often requiring cumbersome fixing steps, which is time-consuming and labor-intensive. Furthermore, disassembly operations are inconvenient for subsequent maintenance or component replacement, increasing labor costs. Second, the connection stability between the device and the installation foundation is insufficient; after long-term use or exposure to vibration, it is prone to loosening or even displacement, affecting detection accuracy. Third, the detection range is limited; a single device cannot cover multiple parking spaces, requiring the deployment of a large number of devices, increasing system costs. Utility Model Content

[0003] Therefore, it is necessary to provide a parking space detector that can accurately detect the status of parking spaces, is easy to install and has a stable structure, and meets the needs of intelligent parking management.

[0004] This utility model provides a parking space detector, comprising:

[0005] Mounting plate;

[0006] The base is detachably mounted on the mounting plate and can move relative to the mounting plate in a preset direction to a locked position;

[0007] The fixing component includes a first fixing member and a second fixing member. One of the first fixing member and the second fixing member is located on the side of the mounting plate facing the base, and the other is located on the side of the base facing the mounting plate. In the locked position, the first fixing member can be fixedly engaged with the second fixing member to limit the displacement of the base in the reverse direction along the preset direction and the displacement in the thickness direction of the mounting plate, thereby preventing the base from moving and unlocking.

[0008] The circuit board is located on the side of the base away from the mounting plate;

[0009] A wide-angle lens is positioned on the side of the circuit board away from the base; and,

[0010] The light-emitting component is mounted on the circuit board and located on the outer periphery of the wide-angle lens.

[0011] This configuration provides a stable mounting base for the parking space detector. The detachable and movable design of the base allows installers to quickly align and lock the base with the mounting plate, improving installation efficiency. It also facilitates easy disassembly for maintenance or component replacement. The first and second fixing components of the fixing assembly work together to effectively limit the base's displacement in the preset direction and the mounting plate's thickness direction when locked, preventing the base from loosening due to external forces or vibrations and thus disengaging from the locked position. The circuit board, as the carrier of the core components, provides a stable platform for the installation and connection of electronic components. The wide-angle lens's positioning ensures maximum coverage of the parking space area, enabling simultaneous monitoring of multiple parking spaces through wide-area imaging. The light-emitting components surrounding the wide-angle lens provide information and guide parking.

[0012] In one embodiment, the mounting plate has mounting holes with interconnected insertion and engagement holes along a preset direction. A protrusion is provided on one side of the base facing the mounting plate. The protrusion can be inserted through the insertion hole and slide along the preset direction to the engagement hole, thereby moving the base relative to the mounting plate to a locked position.

[0013] This design, with its insertion and engagement holes, provides precise guidance and positioning for the base installation, ensuring that the base can slide smoothly into the mounting plate in the correct direction and lock in place.

[0014] In one embodiment, a first fastener is disposed on the side of the mounting plate facing the base and includes an elastic protrusion, and a second fastener is disposed on the side of the base facing the mounting plate and has a groove.

[0015] In the locked position, the elastic protrusion is embedded in the groove.

[0016] This design, with the elastic protrusions and grooves working together, provides a reliable locking mechanism for the base and mounting plate, ensuring that the base will not loosen due to external forces or vibrations after installation.

[0017] In one embodiment, the second fastener further includes a guide ramp connected to the edge of the groove, and when the base moves to the locking position in a preset direction, the elastic protrusion is embedded in the groove along the guide ramp.

[0018] With this configuration, by setting a guide ramp along the edge of the groove, when the elastic protrusion approaches the groove, the guide ramp can guide the elastic protrusion to slide smoothly into the groove.

[0019] In one embodiment, the wide-angle lens is a fisheye lens, and the optical axis of the fisheye lens is perpendicular to the mounting plate.

[0020] This setup, using a fisheye lens as a wide-angle lens, provides an ultra-wide field of view, enabling monitoring of a larger area. Positioning the fisheye lens's optical axis perpendicular to the mounting plate means the lens can capture images vertically downwards or upwards. Combined with its ultra-wide-angle characteristics, this allows a single parking space detector to cover multiple parking spaces.

[0021] In one embodiment, the parking space detector further includes a housing, which includes a cover and a lampshade. The two ends of the lampshade are respectively connected to a base and a seat to form an accommodating space. The cover has a lens hole, and the circuit board and light-emitting components are disposed in the accommodating space. At least part of the wide-angle lens extends out of the lens hole.

[0022] This design provides comprehensive protection for the precision components inside the parking space detector, preventing dust, moisture, and physical impacts from damaging the circuit board, wide-angle lens, and light-emitting components. The cover and lampshade are connected to the base together, forming an enclosure space. The light is evenly distributed through the light transmittance of the lampshade. The wide-angle lens extends through the lens hole to prevent the field of view from being obstructed.

[0023] In one embodiment, the light-emitting component includes a plurality of LEDs, which are respectively disposed on both sides of the circuit board and arranged at intervals along the circumference of the circuit board.

[0024] This configuration ensures that the light-emitting components can emit light evenly into the lampshade from multiple directions.

[0025] In one embodiment, the distance D between any two adjacent LEDs is less than or equal to the distance L from the LED to the outer side of the housing.

[0026] With this configuration, the distance D between adjacent LEDs is small, which ensures that the light is evenly distributed in the area between adjacent LEDs and avoids obvious dark areas or discontinuous light. The distance L between the LED and the housing is large, which ensures that there is enough space for the light to diffuse and be uniform during its propagation through the housing.

[0027] In one embodiment, the parking space detector further includes a speaker assembly disposed within an accommodating space, and the cover has a speaker hole corresponding to the speaker assembly; and / or,

[0028] The parking space detector also includes a sound receiving component installed in the accommodating space, and the cover has a sound receiving hole corresponding to the sound receiving component.

[0029] This configuration, by integrating a speaker component inside the parking space detector and correspondingly opening a speaker hole on the cover, enables the device to have audio output capability; by integrating a receiver component inside the parking space detector and correspondingly opening a receiver hole on the cover, enables the device to have audio input capability.

[0030] In one embodiment, the housing also includes a lens cover that covers the lens aperture.

[0031] This design, by placing a separate lens hood at the lens hole of the housing, provides additional protection for the wide-angle lens. Attached Figure Description

[0047] In the field of intelligent parking management, parking space detectors are key devices for real-time monitoring of parking space status. Their ease of installation, operational stability, and detection accuracy directly affect management efficiency. However, existing parking space detectors have several limitations in practical applications: First, the installation process is complex, often requiring cumbersome fixing steps, which is time-consuming and labor-intensive. Furthermore, disassembly operations are inconvenient for subsequent maintenance or component replacement, increasing labor costs. Second, the connection stability between the device and the installation foundation is insufficient; after long-term use or exposure to vibration, it is prone to loosening or even displacement, affecting detection accuracy. Third, the detection range is limited; a single device cannot cover multiple parking spaces, requiring the deployment of a large number of devices, increasing system costs.

[0048] To solve the above problems, such as Figures 1 to 8 As shown, this utility model discloses a parking space detector that can accurately detect the status of parking spaces, is easy to install and has a stable structure, and meets the needs of intelligent parking lot management.

[0049] like Figure 1 and Figure 3 As shown, this application provides a parking space detector, including a mounting plate 1, a base 2, a fixing component 3, a circuit board 4, a wide-angle lens 5, and a light-emitting component 6. The base 2 is detachably mounted on the mounting plate 1 and can move relative to the mounting plate 1 in a preset direction to a locked position. The fixing component 3 includes a first fixing member 31 and a second fixing member 32. One of the first fixing member 31 and the second fixing member 32 is located on the side of the mounting plate 1 facing the base 2, and the other is located on the side of the base 2 facing the mounting plate 1. In the locked position, the first fixing member 31 can be fixedly engaged with the second fixing member 32 to limit the displacement of the base 2 in the reverse direction along the preset direction and in the thickness direction of the mounting plate 1, preventing the base 2 from unlocking. The circuit board 4 is located on the side of the base 2 away from the mounting plate 1. The wide-angle lens 5 is located on the side of the circuit board 4 away from the base 2. The light-emitting component 6 is located on the circuit board 4 and on the outer periphery of the wide-angle lens 5. Both the wide-angle lens 5 and the light-emitting component 6 are electrically connected to the circuit board 4.

[0050] This design allows the mounting plate 1 to be installed onto external structures such as the ceiling using screws and bolts, providing a stable installation base for the parking space detector and ensuring long-term stable operation in parking lot environments. During installation, the mounting plate 1 is first fixed to the ceiling using bolts or screws. Then, the base 2, attached to the mounting plate 1, is moved along the preset direction to the locking position, completing the installation. Simultaneously, the fixing component 3 locks the device in place. For future maintenance, the device can be easily removed by moving the base 2 out of the locking position. This quick-release design simplifies installation and removal, reducing labor costs. The detachable and movable design of the base 2 allows construction personnel to quickly align and lock the base 2 with the mounting plate 1, improving installation efficiency. Simultaneously, the base 2 can be easily disassembled for maintenance or component replacement. The first fixing member 31 and the second fixing member 32 of the fixing assembly 3 cooperate to effectively limit the displacement of the base 2 in the preset direction and the thickness direction of the mounting plate 1 when locked, preventing the base 2 from loosening due to external force or vibration and thus disengaging from the locked position. This ensures the stability of the parking space detector during operation and prevents damage or safety hazards caused by equipment displacement or falling. The circuit board 4, as the carrier of the core components, provides a stable installation and connection platform for electronic components, ensuring the normal operation of the intelligent functions of the parking space detector. The positioning design of the wide-angle lens 5 ensures that it can cover the parking space area to the maximum extent, achieving simultaneous monitoring of multiple parking spaces through wide-area imaging, improving detection efficiency. The light-emitting component 6 is arranged around the wide-angle lens 5, providing prompts and guiding parking, while also providing uniform illumination in low light conditions, ensuring that the wide-angle lens 5 can clearly capture parking space images, improving the accuracy and reliability of parking space detection.

[0051] like Figures 3 to 4 As shown, in one embodiment, the mounting plate 1 has mounting holes 11. Along a preset direction, the mounting holes 11 have interconnected insertion holes 111 and engagement holes 112. The base 2 has a protrusion 21 on one side facing the mounting plate 1. The protrusion 21 can be inserted through the insertion hole 111 and slide along the preset direction to the engagement hole 112, so that the base 2 moves relative to the mounting plate 1 to a locked position. This design, with its gourd-like insertion hole 111 and engagement hole 112, provides precise guidance and positioning for the installation of the base 2, ensuring that the base 2 can smoothly slide into and lock onto the mounting plate 1 in the correct direction. This design simplifies the installation process, allowing installers to quickly and accurately complete the installation of the base 2, while ensuring a tight fit between the base 2 and the mounting plate 1, preventing the base 2 from loosening or shifting during use, and ensuring the stable operation of the parking space detector.

[0052] Specifically, the protrusion 21 includes a large-diameter section and a small-diameter section. The small-diameter section protrudes from the base 2, and the large-diameter section is located at the end of the small-diameter section away from the base 2. The size of the insertion hole 111 is equal to or slightly larger than the size of the large-diameter section, allowing the protrusion 21 to be inserted into or disengaged from the insertion hole 111. The size of the engaging hole 112 is equal to or slightly larger than the size of the small-diameter section and smaller than the size of the large-diameter section, preventing the protrusion 21 from directly disengaging from the engaging hole 112 in the locked position. The size and shape of the insertion hole 111 and the engaging hole 112 can be optimized based on the size and shape of the protrusion 21 to ensure smooth insertion and tight engagement, reducing installation errors.

[0053] exist Figure 3 In this implementation, the preset direction is a counterclockwise rotation direction.

[0054] In another implementation, the preset direction can be designed as a clockwise rotation direction or a linear sliding direction, depending on the actual installation requirements.

[0055] In the illustrated embodiment, three sets of mounting holes 11 and protrusions 21 are evenly distributed. Of course, the number of mounting holes 11 and protrusions 21 can also be 1, 2, 4 or more. The specific number and arrangement of mounting holes 11 and protrusions 21 can be adjusted according to design requirements. This embodiment of the present invention does not impose specific limitations here.

[0056] In another embodiment, the mounting hole 11 can be designed as a T-shaped groove, an L-shaped groove, or other irregular grooves to accommodate different shaped protrusions 21 for insertion and sliding, increasing design flexibility.

[0057] like Figure 3 As shown, in one embodiment, a first fixing member 31 is disposed on the side of the mounting plate 1 facing the base 2 and includes an elastic protrusion 311. A second fixing member 32 is disposed on the side of the base 2 facing the mounting plate 1 and has a groove 321. In the locked position, the elastic protrusion 311 is embedded in the groove 321. This arrangement provides a reliable locking mechanism between the base 2 and the mounting plate 1, ensuring that the base 2 will not loosen due to external force or vibration after installation. The elastic properties of the elastic protrusion 311 allow it to deform during the installation of the base 2, so that it can smoothly enter the groove 321 during installation. When the base 2 reaches the locked position, the elastic protrusion 311 returns to its original shape and is tightly embedded in the groove 321, forming a stable connection. Simultaneously, when disassembly is required, simply applying force in the opposite direction along the groove 321 will disengage the elastic protrusion 311 and the groove 321 to unlock the device. This design not only improves the connection strength between the base 2 and the mounting plate 1, but also allows for a certain degree of installation error because the elastic protrusion 311 can automatically adjust its position within a certain range to adapt to the groove 321, making the installation process simpler and faster.

[0058] The elastic protrusion 311 can be designed in various shapes, such as hemispherical, cylindrical, square or conical, to adapt to different shaped grooves 321. The depth and opening size of the groove 321 can be adjusted according to the size and elastic characteristics of the elastic protrusion 311 to ensure that the elastic protrusion 311 can be firmly embedded and maintain a stable connection.

[0059] In another embodiment, the second fixing member 32 is disposed on the side of the mounting plate 1 facing the base 2, and the second fixing member 32 is provided with a groove 321. The first fixing member 31 is disposed on the side of the base 2 facing the mounting plate 1 and includes an elastic protrusion 311. In the locked position, the elastic protrusion 311 is embedded in the groove 321.

[0060] like Figures 3 to 5 As shown, in one embodiment, the elastic protrusion 311 includes a spring piece 3111 and a protrusion 3112. One end of the spring piece 3111 is connected to the side of the mounting plate 1 facing the base 2, and the protrusion 3112 is disposed on the side of the spring piece 3111 facing the base 2. With this configuration, the spring piece 3111 can provide elastic support for the protrusion 3112. When the base 2 moves in a preset direction and the protrusion 3112 is compressed, the spring piece 3111 can elastically deform, allowing the protrusion 3112 to smoothly embed into the groove 321 on the second fixing member 32. When the base 2 needs to be unlocked, the spring piece 3111 can return to its elastic deformation, allowing the protrusion 3112 to disengage from the groove 321, achieving convenient unlocking between the base 2 and the mounting plate 1. This design makes the fixing and unlocking operations between the base 2 and the mounting plate 1 simple and efficient, without the need for additional tools or complex operating procedures, reducing the difficulty and cost of installation and maintenance.

[0061] The length, width, and thickness of the spring 3111 can be designed according to the required elastic force and deformation range to meet different locking requirements and service life. The spring 3111 can adopt different shapes and structures, such as straight, curved, wavy, or multi-segment combination shapes, to meet different elastic requirements and spatial layout needs; the shape of the protrusion 3112 can also be adjusted according to the shape of the groove 321, such as being designed as circular, square, triangular, or polygonal, to ensure that the protrusion 3112 can precisely fit with the groove 321.

[0062] In another embodiment, the elastic protrusion 311 may be designed as a structure capable of extending and retracting along the direction of the groove 321.

[0063] like Figures 3 to 6As shown, in one embodiment, the second fixing member 32 further includes a guide slope 322 connected to the edge of the groove 321. When the base 2 moves to the locking position in a preset direction, the elastic protrusion 311 is embedded into the groove 321 along the guide slope 322. With this configuration, by providing a guide slope 322 along the edge of the groove 321, when the elastic protrusion 311 approaches the groove 321, the guide slope 322 can guide the elastic protrusion 311 to smoothly slide into the groove 321. This design avoids possible jamming or impact during the insertion process of the elastic protrusion 311, making the sliding and locking process of the base 2 smoother, reducing wear between components, and improving the installation experience and service life of the equipment, especially in scenarios with frequent installation and disassembly.

[0064] The angle and length of the guide ramp 322 can be optimized according to the shape and size of the elastic protrusion 311 to ensure that the elastic protrusion 311 can slide into the groove 321 along the guide ramp 322 with minimal resistance. The guide ramp 322 can be designed as a straight line, a curve, or a multi-segment combination to adapt to different installation spaces and movement trajectory requirements.

[0065] In one embodiment, the wide-angle lens 5 is a fisheye lens, with its optical axis perpendicular to the mounting plate 1. Specifically, the field of view of a fisheye lens is typically between 100 and 180 degrees, and can exceed 180 degrees with special design. This configuration, using a fisheye lens as the wide-angle lens 5, provides an ultra-wide field of view, enabling monitoring of a larger area. Positioning the fisheye lens perpendicular to the mounting plate 1 means the lens can capture images vertically downwards or upwards. Combined with its ultra-wide-angle characteristics, a single parking space detector can cover multiple parking spaces, significantly improving the monitoring efficiency and coverage of a single device, reducing the number of devices required, and thus lowering deployment costs and installation complexity. In the illustrated embodiment, one parking space detector can monitor 12 parking spaces.

[0066] In another embodiment, the wide-angle lens 5 can also have a field of view smaller than that of the fisheye lens, and can be connected to the circuit board 4 through an adjustable adapter. The adapter can adjust the angle of the fisheye lens within a certain range, so that the optical axis of the fisheye lens can be finely adjusted to the vertical angle deviation with the mounting plate 1 according to the actual installation environment and testing requirements, so as to obtain the best shooting effect.

[0067] like Figure 1 and Figure 7As shown, in one embodiment, the parking space detector further includes a housing 7, which includes a cover 71 and a lampshade 72. The two ends of the lampshade 72 are connected to the base 2 and the cover 71 respectively to form an accommodating space. The cover 71 has a lens aperture 713. The circuit board 4 and the light-emitting component 6 are both located within the accommodating space, with at least a portion of the wide-angle lens 5 extending out of the lens aperture 713. This design of the housing 7 provides comprehensive protection for the internal precision components of the parking space detector, preventing damage to the circuit board 4, wide-angle lens 5, and light-emitting component 6 from dust, moisture, and physical impact, ensuring long-term stable operation of the equipment. The cover 71 and the lampshade 72 are connected to the base 2 to form an accommodating space, which not only constitutes the appearance of the equipment but also cleverly encloses the light-emitting component 6 internally. The light transmittance of the lampshade 72 achieves uniform light distribution, avoiding discomfort to the eyes from direct light. The wide-angle lens 5 extends through the lens aperture 713, preventing obstruction of the field of view and allowing the parking space detection and monitoring functions to be fully utilized.

[0068] The cover 71 and the lampshade 72 can be connected by a snap-fit ​​method. Matching snaps and slots are provided at the connection points of the cover 71 and the lampshade 72. They can be directly snapped together during installation, and are easy to disassemble, making it convenient to maintain and replace the internal components.

[0069] In another embodiment, the cover 71 and the lampshade 72 can also be connected by screws, adhesive or other means.

[0070] In one embodiment, the lampshade 72 has a thickness of 3mm. This design is based on optimized considerations for light uniformity and appearance. The 3mm thickness effectively diffuses the light emitted by the light-emitting component 6, resulting in uniform brightness on the outer light-emitting surface of the lampshade 72. This avoids the graininess or localized dark areas caused by the point light source of the LED beads 61, improving visual effect and clarity of indication. The 3mm thickness also provides the lampshade 72 with sufficient structural strength and durability, making it less prone to damage during daily use and ensuring long-term reliability.

[0071] In another embodiment, the thickness of the lampshade 72 can be finely adjusted according to the desired light transmittance and light diffusion effect. For example, when a lower light transmittance is required, the thickness of the lampshade 72 can be greater than 3 mm; when a stronger light diffusion effect is required, the thickness of the lampshade 72 can be less than 3 mm.

[0072] In another embodiment, different areas of the lampshade 72 are designed with different thicknesses. For example, the area directly above the light-emitting component 6 is thinner to improve the light transmittance in that area; while the thickness is appropriately increased in the edge and corner areas of the lampshade 72 to enhance the strength and protection of these impact-prone areas.

[0073] like Figure 1 and Figure 8 As shown, in one embodiment, the housing 7 further includes a lens hood 73, which covers the lens aperture 713. Specifically, the housing 7 also includes a pressure cap 74, which presses and secures the lens hood 73 to the cover 71. This arrangement, by providing a separate lens hood 73 at the lens aperture 713 of the housing 7 and securing it to the housing 7 with the pressure cap 74, provides additional protection for the wide-angle lens 5. The lens hood 73 effectively blocks dust, moisture, and physical impacts, protecting the wide-angle lens 5 from damage and ensuring its image quality and lifespan. The pressure cap 74 ensures a secure installation of the lens hood 73, preventing it from loosening or falling off, while also facilitating cleaning or replacement of the lens hood 73. This split design provides both excellent protection and ease of maintenance, extending the lifespan of the device.

[0074] In another embodiment, the lens cover 73 can also be fixed to the cover 71 by means of screws, snap-fit, adhesive, etc.

[0075] like Figure 1 As shown, in one embodiment, the light-emitting component 6 can switch between three colors via circuit control of the circuit board 4. This configuration allows for precise circuit control of the light-emitting component 6 via the circuit board 4, enabling it to switch between displaying three different colors, such as red, yellow, and green. This multi-color indicator function can intuitively and quickly convey parking space status information to parking users; for example, red indicates that the parking space is full or faulty, green indicates that there is an available space, and yellow indicates that it is reserved or in a special condition. This visual guidance method greatly improves parking efficiency and user experience, reducing the time and hassle of searching for parking spaces.

[0076] In another implementation, the light-emitting component 6 can achieve more color switching, such as RGB full-color display, to provide richer indication information and personalized settings.

[0077] In another implementation, depending on actual needs, the light-emitting component 6 can also be designed to switch between two colors or display in monochrome.

[0078] like Figure 2 and Figure 8As shown, in one embodiment, the light-emitting component 6 includes a plurality of LED beads 61, which are respectively disposed on both sides of the circuit board 4 and arranged at intervals along the circumference of the circuit board 4. This arrangement, by uniformly arranging the LED beads 61 on both sides of the circuit board 4 at intervals along its circumference, ensures that the light-emitting component 6 can emit light uniformly into the lampshade 72 from multiple directions. This surrounding light source distribution, combined with the thickness design of the lampshade 72, further enhances the uniform diffusion effect of light, making the brightness of the entire light-emitting surface of the lampshade 72 consistent, avoiding areas that are too bright or too dark. This provides clear parking instructions for vehicles approaching from all directions, offering a clear, soft, and grain-free visual effect for parking space status indication, and improving the accuracy of information transmission.

[0079] In the illustrated embodiment, a total of 44 LED beads 61 are arranged on the edge of the circuit board 4, with 22 beads arranged on each side at a uniform spacing.

[0080] In another implementation, the multiple LED beads 61 can be arranged in different ways. For example, the LED beads 61 can be arranged in a spiral on both sides of the circuit board 4. This arrangement allows for a more uniform distribution of light within the shooting area, reducing blind spots. Furthermore, the LED beads 61 can also be arranged in a matrix. By adjusting the spacing and density of the matrix, precise control of the light distribution can be achieved to meet the shooting needs of different scenarios.

[0081] In another implementation, depending on actual needs, the LED 61 may be arranged only on one side of the circuit board 4.

[0082] like Figure 2 and Figure 8 As shown, in one embodiment, the distance D between any two adjacent LED beads 61 is less than or equal to the distance L from the LED bead 61 to the outer surface of the housing 7, i.e., D / L≤1. This configuration ensures that the distance D between adjacent LED beads 61 is small, guaranteeing uniform light distribution within the area between them and preventing obvious dark areas or discontinuous light. The larger distance L from the LED bead 61 to the housing 7 ensures sufficient space for light diffusion and homogenization during propagation through the housing 7, resulting in a uniform brightness across the entire luminous surface of the housing 7. This improves the indicating effect and lighting quality of the parking space detector. This design not only provides clearer and more uniform illumination at night or in low-light environments, making it impossible to see obvious pixelation or other dark areas on the outer surface of the housing 7, thus helping drivers accurately judge the location and status of parking spaces, but also enhances the aesthetics of the parking space detector, making it more eye-catching in parking lots and easier for drivers to quickly spot and identify.

[0083] In another embodiment, the distance D between two adjacent LED beads 61 can be optimized based on the luminous intensity and emission angle of the LED beads 61 and the optical characteristics of the housing 7 to achieve the best uniform light distribution. For example, for LED beads 61 with high luminous intensity and a large emission angle, the distance D can be appropriately increased to avoid excessive light overlap leading to localized overexposure; for LED beads 61 with low luminous intensity and a small emission angle, the distance D can be appropriately decreased to ensure that the light can cover the entire shooting area; the distance L from the LED beads 61 to the housing 7 can be adjusted based on the material and structure of the housing 7. If the housing 7 is made of a material with good light transmittance, the distance L can be appropriately decreased to fully utilize the light scattering effect of the housing 7, making the light more evenly distributed in the shooting area; if the housing 7 is made of a material with poor light transmittance, the distance L needs to be appropriately increased to reduce the obstruction of light by the housing 7 and ensure that sufficient light can reach the shooting area.

[0084] In one embodiment, the LED 61 is a 120° LED. This configuration, with its wide light emission angle, ensures that the light covers the inner surface of the lampshade 72 more extensively, increasing the area and intensity of light overlap, thereby achieving more efficient and uniform light diffusion within a limited space.

[0085] In another embodiment, the LED 61 can adopt other light emission angles, such as 90° or 150°, to adapt to different light distribution requirements and the shape of the lampshade 72.

[0086] In another implementation, LEDs 61 with different light-emitting angles can be used in combination, for example, LEDs 61 with a narrower angle can be used in the central area and LEDs 61 with a wider angle can be used in the edge area to achieve more precise light control.

[0087] In another embodiment, the light-emitting component 6 can be designed as a light strip.

[0088] like Figure 1 and Figure 7 As shown, in one embodiment, the parking space detector further includes a speaker component 8 disposed within the accommodating space, and a speaker hole 711 corresponding to the speaker component 8 is provided on the cover 71. The speaker component 8 is disposed on the cover 71 or the circuit board 4 and is electrically connected to the circuit board 4. This configuration, by integrating the speaker component 8 inside the parking space detector and correspondingly providing a speaker hole 711 on the cover 71, expands the audio output capability while providing visual indication functionality. The speaker component 8 can be used to play voice prompts, guidance information, or warning sounds, such as issuing an alarm when a parking space is occupied or an abnormal situation occurs, or providing a welcome message and parking guidance when a user approaches. This design increases the interactivity and practicality of the device, improves the user experience, and enhances the intelligent management level of the parking lot.

[0089] Among them, the speaker assembly 8 can be a full-range speaker, a bone conduction speaker, or a piezoelectric speaker to adapt to different sound quality, size, and installation requirements.

[0090] like Figure 1 and Figure 7 As shown, in one embodiment, the parking space detector further includes a sound-receiving component 9 disposed within the accommodating space, and a sound-receiving hole 712 corresponding to the sound-receiving component 9 is provided on the cover 71. The sound-receiving component 9 is disposed on the cover 71 or the circuit board 4 and electrically connected to the circuit board 4. This configuration, by integrating the sound-receiving component 9 inside the parking space detector and correspondingly providing a sound-receiving hole 712 on the cover 71, enables the device to have audio input capability; the sound-receiving component 9 can pick up ambient sounds, such as the sound of vehicles entering and exiting, to assist in judging the parking space status; it also enables two-way communication with parking personnel, for example, in an emergency, parking personnel can communicate with the management center via voice to seek assistance. This integrated design greatly improves the intelligence level and emergency response capability of the device, solving the problem of traditional parking space detection devices lacking two-way communication functionality.

[0091] The microphone assembly 9 can use a single microphone, a dual microphone array, or a multi-microphone array to achieve better noise reduction and sound source localization, thereby improving speech clarity.

[0092] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application.
