[0040] Figure 1 It is a structural schematic diagram of a parking space detection device provided by an embodiment of the utility model; Figure 2 is an axonometric cross-sectional view of a parking space detection device provided by an embodiment of the utility model; Figure 3 It is a cross-sectional view of a parking space detection device provided in an embodiment of the utility model.

[0041] See also Figures 1 to 3 The embodiment of the utility model provides a parking space detection device, which includes a base 10, a cover 20, a lampshade 30 and a reflective component 40. The lampshade 30 is located between the base 10 and the cover 20, and is respectively connected to the base 10 and the cover 20 to enclose and form an accommodating space. The reflective component 40 is arranged in the accommodating space and divides the accommodating space into a first area A and a second area B. The first area A is located at the periphery of the second area B. A light source 50 is arranged in the first area A, and a lens assembly 60 is arranged in the second area B. The lens assembly 60 extends out of the cover 20.

[0042] It is equivalent to that the reflective component 40 divides the accommodating space into a first area A and a second area B which are independent of each other, and the two areas are independent of each other and do not interfere with each other. The light source 50 is arranged in the first area A so that the first area A forms a light-emitting area, and other devices such as the lens assembly 60 are arranged in the second area B so that the second area B forms a device installation area. When the light source 50 emits light, part of the light is blocked by the reflective component 40 after being incident on the reflective component 40 and reflected to the position of the lampshade 30 to provide an indication effect, thereby ensuring that the indication effect of the parking space detection device is obvious. In this process, the light emitted by the light source 50 will not enter the area where the lens assembly 60 is located, which can avoid affecting the image acquisition effect of the lens assembly 60.

[0043] It can be understood that the parking space detection device provided by the embodiment of the utility model is provided with a reflective component 40 in the accommodation space formed by the base 10, the cover 20 and the lampshade 30. The reflective component 40 divides the accommodation space into a first area A and a second area B that are independent of each other. The first area A is located at the periphery of the second area B, which is equivalent to the first area A enveloping the second area B. A light source 50 is provided in the first area A, and a lens assembly 60 that can extend out of the cover 20 is provided in the second area B. Such a setting not only improves the light emitting effect of the light source 50, which can ensure that the indication effect of the parking space detection device is obvious, but also prevents the residual light of the light source 50 from entering the position where the lens assembly 60 is located to affect the image acquisition of the lens assembly 60, thereby improving the image acquisition effect of the lens assembly 60.

[0044] Moreover, with such an arrangement, the lampshade 30 is located in the thickness direction of the parking space detection device, and the proportion of the lampshade 30 in the parking space detection device is increased, that is, the lampshade 30 is larger in size, more conspicuous in structure, better in indication effect, and easier to be found by the user.

[0045] Continue reading Figures 1 to 3 In some embodiments of the present invention, the parking space detection device further includes a control board 70. The control board 70 is also the main board or integrated circuit board of the parking space detection device, and is the control center of the parking space detection device.

[0046] The control panel 70 is fixedly connected to the cover 20 by fasteners such as screws, that is, the control panel 70 is screwed to the cover 20. One end of the reflective component 40 is connected to the base 10, and the other end of the reflective component 40 abuts against the upper surface of the control panel 70. The light source 50 is arranged in a circular array near the edge of the control panel 70. Exemplarily, the light source 50 is arranged on both the upper and lower surfaces of the control panel 70 near the edge, which can increase the light output effect.

[0047] The light source 50 may be a lamp bead or a light strip. When the light source 50 is a lamp bead, the light source 50 is arranged in an array around the central circumference of the control panel 70. The lamp bead can display a variety of colors and can display different colors according to the use status of the parking space, so that the user can choose a suitable parking area according to the displayed color and the number of people queuing for parking. For example, the lamp bead is an RGB three-color lamp bead, and the lamp bead can display red, green or blue in real time, wherein a red light indicates that there is a car, a green light indicates that there is no car, and a blue light indicates a reserved parking space.

[0048] Figure 4 It is a partial structural sectional view of the parking space detection device provided in an embodiment of the utility model.

[0049] Continue reading Figure 3 , and also see Figure 4 In some embodiments of the utility model, the reflective component 40 includes a reflective body 41 and a bending portion 42. The reflective body 41 and the bending portion 42 are arranged at an angle to each other. The bending portion 42 is fixed to the inner wall of the base 10 by gluing, and one end of the reflective body 41 away from the bending portion 42 abuts against the upper surface of the control panel 70.

[0050] In other words, the reflective body 41 and the bent portion 42 are both made of opaque material. For example, the reflective body 41 and the bent portion 42 are made of PET material with a smooth surface, which has a good reflective effect. After the light emitted by the lamp bead is reflected by the reflective body 41, it can be transformed from a point light source to a surface light source. After the reflected light passes through the lampshade 30, the indication light emitted by the parking space detection device is more uniform and the indication effect is better.

[0051] Among them, the reflective body 41 can be a cylindrical structure, and the reflective body 41 and the bending portion 42 can be integrally formed, that is, the bending portion 42 is formed by bending one end of the reflective body 41, or a flange is provided along the edge of one end of the reflective body 41 to form the bending portion 42, and adhesive parts such as adhesive are provided on the bending portion 42. The reflective body 41 is adhered to the die-cast base through the adhesive provided on the bending portion 42, and correspondingly, a pasting space or pasting surface is reserved on the base corresponding to the position of the bending portion 42.

[0052] Of course, the reflective body 41 and the bending portion 42 can also be set separately, that is, the reflective body 41 and the bending portion 42 are set as independent parts, and then the reflective body 41 and the bending portion 42 are fixed into an integrated structure by welding or bonding. The specific setting can be selected according to actual usage requirements.

[0053] It should be noted that the inclination angle of the reflective body 41, that is, the reflection angle of the reflective body 41 can be adaptively adjusted according to the structural shape of the lampshade 30 to reflect as much light as possible to the lampshade 30, thereby making the indicator light of the parking space detection device brighter, more uniform, and having a better indication effect.

[0054] Continue reading Figures 2 to 4 In some embodiments of the present invention, a light blocking portion 21 is extended from one side of the cover 20 toward the control board 70 , and the control board 70 abuts against the light blocking portion 21 .

[0055] The light-blocking portion 21 is a cylindrical structure, the interior of the light-blocking portion 21 forms an installation space for installing devices and wiring harnesses, and the outer wall of the light-blocking portion 21 forms a positioning surface or an installation surface.

[0056] The light blocking portion 21 can be integrally formed with the cover body 20 , that is, the cover body 20 can be made of plastic material, and the light blocking portion 21 can be a part of the cover body 20 . The reflective surface of the light blocking portion 21 is mirror-polished to improve the reflection efficiency.

[0057] The light blocking portion 21 is similar to the above-mentioned reflective body 41, both of which are made of opaque material and have a good reflective effect. When the light emitted by the lamp bead is reflected by the reflective body 41, it changes from a point light source to a surface light source. After the reflected light passes through the lampshade 30, the indication light emitted by the parking space detection device is more uniform, so that the indication effect of the parking space detection device is better.

[0058] In addition, by providing a light-blocking portion 21 in cooperation with the reflective body 41 to separate the accommodating space into a first area A and a second area B that are independent of each other, the components and the tail wires of the components in the second area B can be restricted in the second area B by the light-blocking portion 21 to prevent the shadows of the components and the tail wires of the components from affecting the lighting effect of the light source 50. At the same time, the light emitted by the light source 50 can be prevented from entering the lens assembly 60 from the inside of the parking space detection device to affect the image acquisition effect of the lens assembly 60.

[0059] In the embodiment of the utility model, it can be understood that the reflective body 41 reflects the light emitted by the lamp beads located above the control board 70 to the middle and upper part of the lampshade 30 to improve the brightness of the middle and upper part of the lampshade 30. The light blocking portion 21 reflects the light emitted by the lamp beads located below the control board 70 to the middle and lower part of the lampshade 30 to improve the brightness of the middle and lower part of the lampshade 30. Equivalently, the light emitted by the light source 50 can be emitted from one side of the light source 50 after being reflected by the reflective body 41 and the light blocking portion 21, so as to make up for the problem of the light emitting angle of the light source 50 (lamp beads) and the limited number of lamp beads.

[0060] In addition, the angles of the reflective body 41 and the light blocking portion 21 can be adjusted to adjust the direction and incident angle of the incident light, so that the light is directed to the area where the brightness needs to be enhanced, so that the brightness of the entire lampshade 30 area can be enhanced.

[0061] Continue reading Figures 2 to 4 In some embodiments of the present invention, a shading member 71 is provided on one side of the control panel 70 facing the light blocking portion 21, and the light blocking portion 21 abuts against the shading member 71, and the shading member 71 is made of a shading material, such as a rubber pad.

[0062] After the control board 70 is locked, the shading member 71 is pressed against the light blocking portion 21, and the shading member 71 is elastically deformed to make the contact between the shading member 71 and the control board 70 closer, thereby preventing the light emitted by the light source 50 from entering the lens assembly 60 from the inside of the parking space detection device, so as to affect the lens assembly 60 from collecting image information.

[0063] Furthermore, in order to improve the tightness of the connection between the control panel 70 and the light blocking portion 21, a limiting groove 72 is provided on the light blocking member 71, and the light blocking portion 21 is embedded in the limiting groove 72. The limiting groove 72 limits the position of the light blocking portion 21, which can not only provide a positioning function for the connection between the control panel 70 and the cover body 20, but also can further improve the light blocking effect and prevent light from passing through the gap between the control panel 70 and the light blocking portion 21.

[0064] Figure 5 It is a partial structural sectional view of another part of the parking space detection device provided in an embodiment of the utility model.

[0065] Continue reading Figure 2 and Figure 3 , and also see Figure 5 In some embodiments of the present invention, a positioning portion 22 is provided on one of the lampshade 30 and the cover body 20 , and a matching portion 33 that cooperates with the positioning portion 22 for positioning is provided on the other of the lampshade 30 and the cover body 20 .

[0066] The positioning portion 22 may be a positioning protrusion or a positioning column, and the matching portion 33 may be a positioning hole or a positioning groove.

[0067] For example, a positioning protrusion or a positioning column can be provided on the cover 20, and a positioning hole that cooperates with the positioning protrusion or the positioning column for positioning can be provided on the lampshade 30, which can facilitate the installation between the lampshade 30 and the cover 20 and improve the assembly efficiency of the parking space detection device. A positioning protrusion or a positioning column can also be provided on the lampshade 30, and a positioning hole that cooperates with the positioning protrusion or the positioning column for positioning can be provided on the cover 20.

[0068] In addition, a sealing ring is provided between the lampshade 30 and the cover body 20 . A sealing groove may be provided on at least one of the lampshade 30 or the cover body 20 , and the sealing ring is embedded in the sealing groove to achieve sealing between the lampshade 30 and the cover body 20 .

[0069] In addition, the parking position detection device further includes a pressing plate 80 , which is pressed on the lampshade 30 to connect the lampshade 30 with the cover body 20 .

[0070] When assembling the lampshade 30 and the cover body 20, first put the sealing ring into the sealing groove, then align the positioning holes on the lampshade 30 with the positioning posts on the cover body 20, and install the lampshade 30 on the cover body 20. Finally, align the positioning holes on the pressing plate 80 with the positioning posts on the cover body 20, install the pressing plate 80 on the cover body 20, and press the pressing plate 80, the lampshade 30, the sealing ring and the cover body 20 together with screws to achieve sealing.

[0071] Continue reading Figures 2 to 5 In some embodiments of the utility model, the lampshade 30 includes a cover body 31 and an arc portion 32 connected to each other, and one end of the cover body 31 away from the arc portion 32 is connected to the base body 10; the arc portion 32 is connected to the cover body 20, and there is an arc transition between the arc portion 32 and the cover body 20.

[0072] This is equivalent to providing a transition fillet for the lampshade 30 to extend the lighting area of ​​the parking detection device from the side to the bottom, that is, further increasing the structural size of the lampshade 30, expanding the lighting area of ​​the parking detection device, and making the light prompt more eye-catching, so as to improve the recognizability of the parking detection device. In addition, by providing a transition fillet for the lampshade 30, it is also possible to prevent the residual light of the light source 50 from entering the field of view of the lens assembly 60, so as to affect the effect of the lens assembly 60 in collecting images.

[0073] During use, the light blocking portion 21 reflects a portion of light to the area where the transition fillet of the lampshade 30 is located with a thicker wall thickness, so as to enhance the brightness of the thicker area on the wall lampshade 30 and improve the lighting effect.

[0074] It should be noted that the light-blocking portion 21 can adjust its inclination angle according to the shape of the lampshade 30 and the transition radius provided on the lampshade 30, that is, the reflection angle of the light-blocking portion 21 can be adaptively adjusted according to the structural shape of the lampshade 30, so that as much light as possible can be reflected to the lampshade 30, thereby making the indicator light of the parking space detection device brighter, emitting light more evenly, and having a better indication effect.

[0075] It should also be noted that the light-blocking portion 21 and the reflective component 40 may also be integrally formed to form a combined component for blocking and reflecting light; the light-blocking portion 21 may also extend to the base body 10 to omit the provision of the reflective component 40; similarly, the reflective component 40 may also extend to the cover body 20 to omit the provision of the light-blocking portion 21. Any combination of the light-blocking portion 21 is acceptable as long as the functions of blocking and reflecting light can be achieved and the internal space of the parking space detection device can be divided into two independently provided spaces.

[0076] Figure 6 It is a schematic diagram of the structural decomposition of the parking space detection device provided in an embodiment of the utility model.

[0077] See also Figures 1 to 5 , and see Figure 6 In some embodiments of the present invention, a speaker 90 and a microphone 100 are further provided on the cover 20 of the parking space detection device, and the speaker 90 and the microphone 100 are located on the periphery of the lens assembly 60 .

[0078] The lens assembly 60 includes a lens 61 and a lens cover 62, the lens cover 62 is connected to the cover body 20, and the lens 61 is installed in the lens cover 62. The lens 61 is a fisheye lens 61, and the structure of the fisheye lens 61 is simple and fixed, and occupies a small space inside the whole machine. In this embodiment, the field of view of the fisheye lens 61 is greater than 180°, for example, the field of view of the fisheye lens 61 is 186°, which enables the parking space detection device to use a lens 61 to provide a 360° recognition range for the parking space detection device, realize multi-directional and multi-parking space detection, and then realize that one parking space detection device corresponds to multiple parking spaces for detection.

[0079] Finally, it should be noted that in the embodiment of the utility model, the lampshade 30 is a light-transmitting material with a light-evening effect, the cover 20, the base 10 and the reflective component 40 are all made of opaque materials, and the area where the lampshade 30 is located is the lighting area.

[0080] Continue reading Figure 6 When assembling the parking space detection device provided by the embodiment of the utility model, the light-emitting component is first glued and fixed on the base body 10 to form a first assembly, and then the lampshade 30 and the control board 70 are fixed on the cover body 20 to form a second assembly. Finally, the first assembly and the second assembly are fixed with screws to complete the assembly, which has higher assembly efficiency.

[0081] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it.
