[0040] The following combination Figures 1 to 6 A holographic projection system for a vehicle according to an embodiment of the present invention is described.

[0041] like Figure 1 and Figure 2 As shown, the holographic projection system for a vehicle according to the embodiment of the present invention includes: an exhaust pipe 100 , a controller 200 , a water tank 300 , a cooling pipe 400 , an atomizing assembly 500 and a holographic projection assembly 600 .

[0042] The water tank 300 is located inside the rear bumper. One end of the cooling pipe 400 is connected to the exhaust pipe 100, and the other end of the cooling pipe 400 is connected to the water tank 300. The cooling pipe 400 can cool the exhaust gas from the exhaust pipe 100, condensing the water vapor in the exhaust gas into liquid water, which is then discharged into the water tank 300.

[0043] The atomization assembly 500 includes an atomizer 501 and a nozzle 502. The atomizer 501 is connected to the bottom of the water tank 300, and the nozzle 502 extends from the rear bumper. The atomizer 501 is electrically connected to the controller 200 and performs an atomization operation under the control of the controller 200 to atomize the liquid water in the water tank 300 into water mist, and spray the water mist to the outside of the rear bumper through the nozzle 502.

[0044] The holographic projection assembly 600 is disposed in the inner space of the rear bumper and is electrically connected to the controller 200 . The holographic projection assembly 600 includes a transmitting device 601 , which extends out of the rear bumper.

[0045] Here, under the control of the controller 200 , the holographic projection assembly 600 can generate different light rays, and project the different light rays onto the water mist outside the rear bumper through the emitting device 601 to generate different patterns.

[0046] This embodiment of the utility model incorporates a water tank 300, an atomizer assembly 500, and a holographic projection assembly 600 on the vehicle's rear bumper. This liquefies the water vapor in the exhaust gas from the exhaust pipe 100 and collects it in the water tank 300. This vapor then forms a mist with the atomizer assembly 500, which serves as the projection medium. This eliminates the need for a rooftop water tank and eliminates reliance on weather conditions, allowing for continuous replenishment of the water tank. Compared to rainwater collection solutions, the water tank no longer contains impurities found in rainwater, reducing the need for cleaning the water tank 300. Furthermore, the nozzle 502 and emitter 601 are only located on the exterior of the rear bumper, which does not affect the vehicle's overall appearance.

[0047] The controller 200 and the onboard computer may be independent of each other and disposed on the vehicle body, or the controller 200 may be integrated into the onboard computer.

[0048] In an exemplary embodiment, Figure 3A As shown, the cooling pipe 400 includes a cooling pipe body 401 and a coolant pipe 402 .

[0049] One end of the cooling pipe body 401 is connected to the exhaust pipe 100 , and the other end of the cooling pipe body 401 is connected to the water tank 300 . A portion of the exhaust gas from the exhaust pipe 100 flows through the cooling pipe body 401 .

[0050] The coolant pipe 402 is disposed inside the cooling pipe body 401 . The coolant pipe 402 contains coolant, which can cool the water vapor in the exhaust gas in the cooling pipe body, so that the water vapor is condensed into liquid water.

[0051] Figure 3A This is just an example of one form of the cooling pipe 400 . The type of the cooling pipe 400 is not limited thereto and can be any form in the prior art as long as it can achieve the above functions.

[0052] In the embodiment of the present invention, the heat exchange process of the coolant in the coolant pipe 402 of the cooling pipe 400 is a conventional process and will not be described in detail here. The coolant circulates in the cooling pipe.

[0053] In an exemplary embodiment, Figure 3B As shown, the cooling pipe 400 is divided into an ascending pipe 403 and a descending pipe 404 in its length direction. One end of the ascending pipe 403 is connected to the upper surface of the exhaust pipe 100, and one end of the descending pipe 404 is connected to the water tank 300. The position where the ascending pipe 403 and the descending pipe 404 are connected is the highest point 405, and the height of the highest point 405 is higher than the height of the part of the descending pipe 404 close to the water tank 300.

[0054] The exhaust gas temperature is high, and it will automatically rise and diffuse into the rising pipe 403 of the cooling pipe 400 and enter the descending pipe 404. Only a part of the exhaust gas in the exhaust pipe 100 enters the cooling pipe 400 to ensure that the drainage efficiency of the vehicle itself is not affected.

[0055] Furthermore, the cooling pipe 400 cools the exhaust gas only in the downcomer 404 , so that the water vapor in the exhaust gas condenses into liquid water only in the downcomer 404 , and the liquid water flows into the water tank along the downcomer 404 without flowing back into the exhaust pipe 100 .

[0056] In an exemplary embodiment, the upper portion of the side wall or top wall of the water tank 300 has a through hole to connect the internal space of the water tank 300 to the external environment, and the water vapor in the exhaust gas entering the cooling pipe 400 is condensed into liquid water, while other components in the exhaust gas enter the water tank 300 through the cooling pipe 400 and are located above the liquid water, and can be discharged to the external environment through the through hole.

[0057] In an exemplary embodiment, Figure 1 As shown, the atomizing assembly 500 further includes a connecting pipe 503 and a water pump (not shown in the figure). The water pump is arranged in the water tank 300. One end of the connecting pipe 503 is connected to the atomizer 501, and the other end of the connecting pipe 503 is connected to the water pump. Specifically, the water pump is arranged at the bottom of the internal space of the water tank 300.

[0058] The water pump pumps the water in the water tank 300 to the atomizer 501 , and the atomizer 501 atomizes the water and sprays the water to the outside of the rear bumper through the nozzle 502 .

[0059] In an exemplary embodiment, a plurality of spray heads 502 are provided.

[0060] In one embodiment, Figure 4A As shown, multiple nozzles 502 are arranged in a circumferential direction with the emitting device 601 as the center.

[0061] In another embodiment, Figure 4B As shown, the nozzle 502 is arranged above the emitting device 601.

[0062] In one embodiment, Figure 5A As shown, the nozzle 502 and the emitting device 601 are arranged on the left side of the rear bumper to generate a holographic projection on the left side of the vehicle.

[0063] In another embodiment, Figure 5B As shown, the nozzle 502 and the emitting device 601 are arranged on the right side of the rear bumper to generate a holographic projection on the right side of the vehicle.

[0064] In yet another embodiment, Figure 5C As shown, the nozzle 502 and the emitting device 601 are arranged on the rear side of the rear bumper to generate a holographic projection on the rear side of the vehicle.

[0065] The manufacturer can adjust the position of the nozzle 502 and the emitting device 601 to adjust the position of the generated holographic projection. For example, the nozzle 502 and the emitting device 601 can be set simultaneously on the left side, right side and rear side of the rear bumper.

[0066] The holographic projection component 600 may include any suitable projection device known in the art that can project images in the air using holographic projection technology, such as a water mist projector.

[0067] The emitting device 601 of the holographic projection assembly 600 projects light onto the water mist to generate an image on the water mist. The image can be an image of a vehicle logo, a triangular warning sign, or other custom image. In one embodiment, the image of the vehicle logo can be generated on the left side of the vehicle, while the triangular warning sign can be generated on the right side of the vehicle.

[0068] In an exemplary embodiment, Figure 2 As shown, the holographic projection system for a vehicle of the utility model embodiment further includes a display 800, which is electrically connected to the controller 200. The display 800 can display image options, which are used to prompt the user to select an image. The displayed image options can include an image of the vehicle's logo, a triangular warning sign, or other customized images. The display 800 can also receive a user's selection operation and generate a first trigger signal based on the received selection operation. The display 800 can send the first trigger signal to the controller 200, and the controller 200 can generate a first control signal and a second control signal based on the first trigger signal, and send the first control signal to the holographic projection component 600, and send the second control signal to the atomization component 500.

[0069] The atomizing assembly 500 can generate and spray water mist according to the second control signal, and the holographic projection assembly 600 can generate corresponding light according to the first control signal to generate a corresponding pattern on the water mist. Specifically, the user can click on the triangular warning sign among the multiple image options on the display 800, and the holographic projection assembly 600 will form a triangular warning sign pattern on the water mist.

[0070] In an exemplary embodiment, Figure 2As shown, the holographic projection system for a vehicle according to an embodiment of the present invention further includes a liquid level sensor 700, which is arranged inside the water tank 300 and electrically connected to the controller 200. The liquid level sensor 700 can sense whether the water level inside the water tank 300 is lower than a preset threshold, and generates a second trigger signal when sensing that the water level is lower than the preset threshold, and sends the second trigger signal to the controller 200.

[0071] The controller 200 can generate a third control signal according to the second trigger signal, and can send the third control signal to the display 800 .

[0072] The display 800 can generate prompt information according to the third control signal, and the prompt information is used to prompt the user to replenish the water in the water tank by starting the engine.

[0073] The present invention also provides a vehicle equipped with the aforementioned holographic projection system for a vehicle. Other components and functions of the vehicle of the present invention are well known to those skilled in the art and will not be described in detail to reduce redundancy.

[0074] The vehicle can be a fuel vehicle, a hydrogen vehicle or other vehicle that can generate exhaust gas.

[0075] Figure 6 The flowchart of the control method of the holographic projection system for a vehicle according to the embodiment of the present invention is shown.

[0076] In step S910, the display 800 receives a user's selection operation to obtain the projection function selected by the user. Specifically, the display 800 receives the user's selection operation (e.g., the user selects the triangular warning sign) and generates a first trigger signal based on the received selection operation. The display 800 sends the first trigger signal to the controller 200.

[0077] In step S920 , the liquid level sensor 700 determines whether the water level inside the water tank 300 is lower than a preset threshold.

[0078] As a result of step S920, if the water volume is greater than or equal to the preset threshold, in step S930, corresponding light is generated according to the projection function. The controller 200 generates a first control signal based on the first trigger signal and sends the first control signal to the holographic projection assembly 600. The holographic projection assembly 600 generates corresponding light according to the first control signal.

[0079] As a result of step S920, if the water volume is greater than or equal to the preset threshold, water mist is generated and sprayed out in step S940. Specifically, the controller 200 generates a second control signal based on the first trigger signal and sends the second control signal to the atomizing assembly 500. The atomizing assembly 500 generates water mist and sprays the water mist out according to the second control signal.

[0080] In step S950, the holographic projection assembly 600 generates corresponding light to generate corresponding patterns on the water mist (eg Figure 1 (with a symbolic triangle warning sign).

[0081] As a result of step S920, if the water level is less than the preset threshold, the display 800 prompts the user to start the engine in step S960. Specifically, when the water level in the water tank 300 is less than the preset threshold, the liquid level sensor 700 generates a second trigger signal and sends the second trigger signal to the controller 200. The controller 200 generates a third control signal based on the second trigger signal and sends the third control signal to the display 800. The display 800 generates a prompt message based on the third control signal, prompting the user to start the engine to replenish the water in the water tank.

[0082] In step S970 , the user starts the engine, replenishes water in the water tank 300 , and executes steps S930 , S940 , and S950 .
