Detailed Implementation

[0020] The present invention will be further explained below with reference to the accompanying drawings.

[0021] This utility model discloses a car wheel hub light, including a lamp housing and an LED light panel for lighting. The lamp housing is installed on the car wheel hub, and the LED light panel for lighting is installed inside the lamp housing to illuminate the lamp housing. The lamp housing is provided with a projection device for generating a projected pattern on the ground.

[0022] The projection device is either a film lens type projection device or a microlens array projection device. Among them, the film lens type projection device is an existing structure and will not be described in detail here.

[0023] The microlens array projection device used in this invention includes a pattern projection array 4, a light source, and a controller. The light source includes a projection LED light panel 7 and collimating lenses 5. The projection LED light panel 7 is equipped with multiple LEDs. The number of collimating lenses 5 is the same as the number of LEDs and they correspond one-to-one. They are used to collimate the light emitted by the LEDs. The controller is connected to both the projection LED light panel 7 and the illumination LED light panel 3 to generate LED driving current. The pattern projection array 4 is illuminated by the LEDs, thereby producing a projected pattern on the ground. The pattern projection array 4 is an existing structure, such as the optical projection device array disclosed in CN105209294A.

[0024] like Figures 1 to 3As shown, the lamp housing includes a cover 1 and a fixing clip 11. The lower end of the fixing clip 11 is fixed to the wheel hub cover 14 of the car wheel hub through a buckle structure. The upper end of the fixing clip 11 is threadedly connected to the lower end of the cover 1. The side of the cover 1 is provided with a projection lamp mounting slot 2 for mounting a projection device.

[0025] like Figure 3 and 4 As shown, the buckle structure includes a snap-fit ​​part 12 spaced apart at the lower end of the fixing clip 11, an elastic clip 13, and a mounting hole 15 located at the center of the wheel hub cover plate 14. The fixing clip is inserted into the mounting hole 15 of the wheel hub cover plate 14 from top to bottom. The snap-fit ​​part abuts against the outer side of the wheel hub cover plate, and the elastic clip abuts against the inner side of the wheel hub cover plate.

[0026] During installation, the elastic buckle 13 needs to be squeezed. When the elastic buckle 13 is compressed, the lower end of the fixing clip 11 can be inserted from top to bottom into the mounting hole 15 of the wheel hub cover plate 14 until the locking part 12 at the lower end of the fixing clip 11 abuts against the outside of the wheel hub cover plate 14. Then, the elastic buckle 13 is released. When the elastic buckle 13 rebounds and abuts against the inside of the wheel hub cover plate 14, the wheel hub cover plate 14 is clamped from both sides by the locking part 12 at the lower end of the fixing clip 11 and the elastic buckle 13, thereby fixing the lamp housing to the wheel hub cover plate. When removing the lamp housing, a tool is inserted into the gap between the lower end of the fixing clip 11 and the mounting hole 15 of the wheel hub cover plate 14 and the elastic buckle 13 is squeezed to remove the lamp housing.

[0027] In addition, the lamp housing contains a lithium battery 8, a heat dissipation base 9, and a counterweight 10. The lithium battery 8 is connected to the projection LED panel 7 and the lighting LED panel 3, providing them with power. The top of the heat dissipation base 9 is attached to the lower side of the projection LED panel 7 and the lighting LED panel 3, allowing the heat generated by the LED panels during operation to be conducted to the lower side of the lamp housing through the heat dissipation base 9. A counterweight is installed on the lower side of the heat dissipation base to maintain the dynamic balance of the car wheel hub.

[0028] To facilitate the installation and positioning of the pattern projection array 4, a lens bracket 6 is provided on the side of the collimating lens 5. The lens bracket 6 is embedded in the projection lamp mounting slot 2. A groove is provided on the upper side of the lens bracket 6. The pattern projection array 4 is embedded in the groove for fixation. The lower side of the lens bracket 6 abuts against the projection lamp plate and the lower side of the lens bracket 6 abuts against the projection LED lamp plate 7.

[0029] The controller is wirelessly connected to the projection LED panel 7 and the lighting LED panel 3 via Bluetooth or Wi-Fi. The controller is either the car's main control computer or a mobile phone, allowing for convenient control of the projection LED panel 7 and the lighting LED panel 3 for the car's wheel hub lights. When the vehicle speed reaches the set value, the projection LED panel 7 and the lighting LED panel 3 automatically light up, or are directly illuminated by the controller.

[0030] In one embodiment of this invention, the pattern projection array structure in a microlens array projection device comprises N pattern projection arrays, where N is greater than or equal to 1. When N equals 1, the pattern projection array includes multiple different partitions, each of which can be illuminated by at least one LED light, thereby generating a projected pattern on the ground. The projected patterns generated by different partitions of the pattern projection array are identical and overlap with each other. When N is greater than 1, different pattern projection arrays can be illuminated by at least one LED light, thereby generating projected patterns on the ground. The projected patterns generated by different pattern projection arrays are identical and overlap with each other. In this embodiment, the microlens array projection device can generate static pattern projections.

[0031] In another embodiment of this invention, the number of pattern projection arrays is N, where N is greater than or equal to 1. When N equals 1, the pattern projection array contains multiple different partitions, each of which can be illuminated by at least one LED light, thereby producing a projected pattern on the ground. Different partitions of the pattern projection array produce different parts of the projected pattern, and these different parts combine to form a complete projected pattern. When N is greater than 1, different pattern projection arrays can be illuminated by at least one LED light, thereby producing a projected pattern on the ground. Different pattern projection arrays produce different parts of the projected pattern, and these different parts combine to form a complete projected pattern. In this embodiment, the microlens array projection device can produce static pattern projections.

[0032] In another embodiment of this utility model, the number of pattern projection arrays is N, where N is greater than or equal to 1. When N equals 1, the pattern projection array contains multiple different partitions, each of which can be illuminated by at least one LED light, thereby producing a projected pattern on the ground. The projected patterns produced by different partitions of the pattern projection array are different. When N is greater than 1, different pattern projection arrays can be illuminated by at least one LED light, thereby producing a projected pattern on the ground. The projected patterns produced by different pattern projection arrays are different. Furthermore, the different projected patterns contain a common repeating part, specifically, the repeating part is the point, line, or surface of the projected pattern. In this embodiment, the microlens array projection device can produce dynamic pattern projection. When the car wheel hub light is working, the controller controls the on / off of multiple LED lights. At the same time, the light intensity of different projected patterns is different. The display effect of different projected patterns produced by multiple different partitions of the pattern projection array or the combination of different projected patterns produced by different pattern projection arrays is different at different times. The combination of patterns at different times is projected onto the ground in a chronological order, giving the observer the illusion of dynamic changes in the pattern content, that is, producing dynamic pattern projection.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
