[0016] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0017] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. Conversely, when an element is said to be "directly on" another element, there is no intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0019] like Figures 1 to 2 As shown, a pedestrian crossing alarm device for a passenger vehicle is characterized by comprising a housing, the housing including a front cover 1 and a rear cover 2, a PCBA board 3 disposed between the front cover 1 and the rear cover 2, the PCBA board 3 being connected to the vehicle's CAN bus, the PCBA board 3 being provided with a plurality of indicator lights 4, the indicator lights 4 being RGB LED lights, the front cover 1 being provided with through holes 11 corresponding to the indicator lights 4, and a cover plate 5 being provided on the outer side of the front cover 1, the cover plate 5 being provided with an indication pattern.

[0020] At this time, the PCBA board 3 has a built-in instruction set. When the vehicle's sensor detects a person approaching, the host sends an instruction, and the indicator light 4 emits the corresponding color according to the instruction, thereby displaying the prompt pattern on the cover plate 5 and forming a corresponding alarm. At this time, RGB LED lights are used, which have multiple colors and can form different alarm prompts. At the same time, RGB LED lights are low in cost, have a long lifespan, and are not easily damaged, thereby extending the overall service life of the alarm device.

[0021] The prompt patterns on the cover plate 5 are designed according to actual needs. In this embodiment, since the main purpose is to detect pedestrians crossing, vehicle patterns are provided. Pedestrian prompt patterns are provided on the left, right and top sides of the vehicle pattern to indicate that pedestrians are crossing on the left, right and front sides of the vehicle. At the same time, fault alarm, maintenance and other patterns are provided below the above patterns to form more prompts.

[0022] After setting the prompt pattern, the RGB LED light can be projected onto the outer side through the pattern at the corresponding position. When viewed from the outside of the cover plate 5, the corresponding pattern will be displayed.

[0023] In order to better observe the effect of the indicator light 4 after it is lit from the outside of the cover plate 5, in this embodiment, the cover plate 5 is a semi-transparent PC board. With the cover plate 5 made of a semi-transparent PC board, if the corresponding RGB LED light emits a specific color, in addition to the corresponding pattern being brighter, the cover plate 5 as a whole also has a certain brightness, thus achieving a better indication effect.

[0024] At this point, the cover plate 5, the front cover 1, and the rear cover 2 need to be fixed together. Specifically, the front cover 1 and the rear cover 2 are fixed together with fasteners, and the cover plate 5 is fixed to the outside of the front cover 1 with adhesive. The front cover 1 and the rear cover 2 are fixed together with fasteners, and the PCBA board 3 is snapped on or fastened through, so that the PCBA board 3 is fixed in the middle position of the front cover 1 and the rear cover 2, thereby forming the main body of the alarm device. Then, the cover plate 5 is fixed to the outside of the front cover 1 with adhesive. The overall structure is simple and the production cost is low.

[0025] At this time, when fixing the cover plate 5 to the front cover 1, in order to ensure the accuracy of their position after fixing, in this embodiment, the outer side of the front cover 1 is provided with a groove 12 that matches the shape of the cover plate 5, and the cover plate 5 is fixed in the groove 12. After the cover plate 5 is fixed in the groove 12, the prompt pattern on the cover plate 5 corresponds to the through hole 11 of the front cover 1, so that the RGB LED light passes through the through hole 11 and illuminates the prompt pattern position, ensuring that the corresponding prompt pattern can be better displayed.

[0026] As for the main body of the alarm device, it also needs to be fixed in the parking space. Therefore, in this embodiment, the outer side of the rear cover 2 is provided with a fixing structure for fixing the alarm device inside the vehicle.

[0027] Specifically, the fixing structure includes a first annular tooth 61 located on the outside of the back cover 2, a rotating part 62 is provided on the outside of the first annular tooth 61, the rotating part 62 is provided with a second annular tooth 63 corresponding to the first annular tooth 61, the rotating part 62 and the back cover 2 are provided with a rotating shaft 64, and when the rotating part 62 and the back cover 2 rotate, the first annular tooth 61 and the second annular tooth 63 are engaged in different positions. The rotating part 62 and the rear cover 2 are connected together by a rotating shaft 64, allowing relative rotation between them. Specifically, the rotating shaft 64 is located on the outer side of the rear cover 2, and a rotating hole is provided in the middle of the rotating part 62. The rotating part 62 is sleeved on the outer side of the rotating shaft 64 through the rotating hole. The outer side of the rotating part 62 is connected to the rotating shaft 64 by screws. At this point, it is necessary to allow relative rotation between the rotating part 62 and the rotating shaft 64. The screws are only used to restrict the separation of the rotating part 62 and the rotating shaft 64. After the rotating part 62 rotates, in order to fix the rotating part 62 and the rear cover 2 after rotation... The rotating part 62 is positioned at the angle after rotation. At this time, the outer side of the back cover 2 is provided with a first ring tooth 61, and the rotating part 62 is provided with a second ring tooth 63 corresponding to the first ring tooth 61. In this way, when the rotating part 62 rotates to any angle position, the first ring tooth 61 and the second ring tooth 63 will be used to make the position of the rotating part 62 and the back cover 2 determined. That is, after rotating to any angle position, the rotating part 62 and the back cover 2 will not have the problem of "slipping" (an external force is required to make the rotating part and the back cover rotate; when no external force is applied, the rotating part and the back cover are relatively fixed and will not rotate due to the interlocking action of the first ring tooth 61 and the second ring tooth 63).

[0028] Furthermore, to secure the alarm device body inside the vehicle and adjust its angle, in this embodiment, a fixing part 65 is provided on the outer side of the rotating part 62. The fixing part 65 is rotatably connected to the rotating part 62 via a hinge, and the fixing part 65 is provided with a fixing hole 66. The fixing part 65 is fixed to the vehicle body through the fixing hole 66 and simultaneously fixed to the rotating part 62 via the hinge rotation structure. In this way, the fixing part 65 and the rotating part 62 can be adjusted to a specific angle position, thereby facilitating user observation.

[0029] In another embodiment, a vehicle employs the aforementioned passenger vehicle pedestrian crossing alarm device.

[0030] 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. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0031] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
