Description

Technical Field

[0001] The invention relates to the field of vehicle lamp defoggers, and in particular to a defogger vehicle lamp and a vehicle having the same. Background Art

[0002] Vehicle lamps have light sources inside, which generate heat. Heat causes the air pressure inside the lamp to increase, so the lamps must have a breathable structure, otherwise the lamps will crack due to excessive internal air pressure. Because the lamps are not completely sealed, fog may be generated.

[0003] The invention patent with application number 201210272592.3 discloses a headlight defog system and a car with the headlight defog system. The headlight defog system is installed in the whole vehicle, and the whole vehicle includes a headlight and an air inlet slot and an exhaust hole set on the headlight; the headlight defog system includes a ventilation grid, a cooling fan, a defog duct and a guide area inside the headlight; the ventilation grid and the cooling fan are both installed on the whole vehicle, and the cooling fan faces the ventilation grid; the guide area inside the headlight is a cavity formed between the air inlet slot and the exhaust hole in the front area of ​​the headlight; the two ends of the defog duct are respectively connected to the cooling fan and the air inlet slot. The invention patent has the following defects: 1. The fan is placed inside the lamp to accelerate the air circulation inside the lamp, resulting in an increase in the power of the lamp. At the same time, when there is no fog in the lamp, the fan is still running, resulting in power waste; 2. This scheme cannot allow members to choose the opening and closing of the fan inside the lamp by themselves, and cannot realize the information interaction between members and the headlight.

[0004] The invention patent with application number 202110787076.3 discloses a new type of headlight defogger structure, including a headlight mask and a headlight housing. The headlight mask and the headlight housing are encapsulated as one. The headlight housing is provided with an internal air pressure balance device, a protective structure for the internal air pressure balance device, an external air pressure balance device and a protective structure for the external air pressure balance device. The internal air pressure balance device and the external air pressure balance device both adopt a telescopic tube structure with a sealing effect, which can shrink with the change of air pressure, change the volume inside the lamp to achieve air pressure balance, and the headlight structure adopts a fully enclosed package. This invention patent has the following defects: 1. A desiccant is placed in the lamp, and the defogger has a time limit, which can be as long as half a year or as short as half a month, and is greatly affected by the environment; 2. After the desiccant is saturated with moisture, its size will become larger, requiring a larger internal space for the headlight; 3. In most cases, the desiccant cannot be replaced, and only the headlight assembly can be replaced.

[0005] In addition, there is also anti-fog paint sprayed on the inner surface of the lampshade. The lampshade is sprayed with anti-fog paint, but the anti-fog paint becomes ineffective when exposed to high temperatures. This solution is limited by the process. For example, the glue-coated headlights can be sprayed with anti-fog paint, but the hot plate welding of the taillights cannot be sprayed with anti-fog paint, because during hot plate welding, the hot plate mold will heat the lampshade to a high temperature, which will cause the anti-fog paint to fail.

For those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted. The positional relationship described in the drawings is only for exemplary description and cannot be understood as a limitation on this patent.

[0040] Reference Figure 1-11 The present invention discloses a defogger lamp and a vehicle having the same.

[0041] For details, please refer to Figure 1-5 :

[0042] The defogger lamp comprises a lamp housing 1, an outer cover 2, a lining frame 3, an inner cover 4, a light-emitting module 5 and an opening and closing mechanism 8; wherein, after the lamp housing 1 and the outer cover 2 are assembled, an accommodating cavity is formed inside, the lining frame 3 is arranged in the accommodating cavity and divides it into an outer chamber 6 and an inner chamber 7, the outer chamber 6 is a space formed between the outer cover 2 and the lining frame 3, and the inner chamber 7 is a space formed between the lining frame 3 and the lamp housing 1; gaps connecting the outer chamber 6 and the inner chamber 7 are left on both the left and right outer sides of the lining frame 3, an inner cover 4 and a light-emitting module 5 corresponding to the inner cover 4 are arranged on the lining frame 3, and an air inlet and outlet 11 is arranged on the lamp housing 1 corresponding to the inner chamber 7; a breathing hole 31 connecting the outer chamber 6 and the inner chamber 7 is arranged on the lining frame 3, and the defogger lamp also comprises an opening and closing mechanism 8 for opening and closing the breathing hole 31.

[0043] The space of the inner chamber 7 near the light emitting module 5 is set as a hot zone 71 , and the space of the inner chamber 7 away from the light emitting module 5 is set as a cold zone 72 .

[0044] In one embodiment:

[0045] The opening and closing mechanism 8 includes a breathing cover 81 and a driving assembly. The breathing cover 81 is adapted to the breathing hole 31. The driving assembly can drive the breathing cover 81 to rotate relative to the breathing hole 31 to open and close the breathing hole 31. The breathing cover 81 is rotatably connected to the breathing hole 31 through a pin or other connection method. The driving assembly can use a motor or other driving mechanism to drive the breathing cover 81 to rotate relative to the breathing hole 31, thereby realizing the opening and closing of the breathing hole 31.

[0046] See also Figure 2-4 , in one embodiment:

[0047] The opening and closing mechanism 8 includes a breathing cover 81 and a driving assembly, the driving assembly includes a travel push rod 82 and a travel power mechanism 83, the breathing cover 81 is clearance-matched with the breathing hole 31, the breathing cover 81 is fixedly connected to the travel push rod 82, the other end of the travel push rod 82 is fixedly connected to the output end of the travel power mechanism 83, and the travel power mechanism 83 can push the breathing cover 81 to move linearly through the travel push rod 82 to open and close the breathing hole 31.

[0048] Under normal conditions, the size of the gap between the breathing hole 31 and the breathing cover 81 (including the fourth gap 94 and the fifth gap 95) is designed to be 0.5 mm, which will not affect the appearance of the car lamp; in the defog state, the size of the gap between the breathing hole 31 and the breathing cover 81 (including the sixth gap 96 and the seventh gap 97) is designed to be 15 mm, which can increase the air circulation between the outer chamber 6 and the inner chamber 7.

[0049] The travel power mechanism 83 is fixed on the inner wall of the lamp housing 1. The travel power mechanism 83 can be a telescopic power cylinder or a telescopic motor. The output ends of the telescopic power cylinder or the telescopic motor are fixedly connected to the travel push rod 82. The telescopic power cylinder can be a hydraulic cylinder, a pneumatic cylinder or other forms. The breathing cover 81 can be single or multiple, and the shape can also be circular, rectangular or other shapes, without limitation. The breathing cover 81 is fastened to the travel push rod 82 by screws 84.

[0050] It can be seen from the above mechanism design that in the defogger state, starting the travel power mechanism 83 can drive the breathing cover 81 forward or backward away from the breathing hole 31 through the travel push rod 82 to open the breathing hole 31, thereby increasing the ventilation volume and enhancing the defogger effect.

[0051] See also Figure 4-7 , in one embodiment:

[0052] A first gap 91 connecting the outer chamber 6 and the inner chamber 7 is left on the left outer side of the lining frame 3, and a second gap 92 connecting the outer chamber 6 and the inner chamber 7 is left on the right outer side; the width of the outer chamber 6 is set to a third gap 93; under normal conditions, the gaps between the breathing hole 31 and the breathing cover 81 are a fourth gap 94 and a fifth gap 95, and under the defog state, the gaps between the breathing hole 31 and the breathing cover 81 are a sixth gap 96 and a seventh gap 97.

[0053] The light-emitting module 5 is arranged adjacent to the first gap 91, the breathing hole 31 is located between the inner mask 4 and the second gap 92, and the air inlet and outlet 11 is located on the side of the breathing hole 31 away from the inner mask 4 in the horizontal direction; the air inlet and outlet 11 is arranged on the back side of the lamp housing 1 opposite to the inner mask 4, and a breathable membrane 12 is laid on the air inlet and outlet 11.

[0054] The design dimensions of the gaps between the internal parts of the lamp are described in detail as follows: the design dimensions of the first gap 91 and the second gap 92 are usually 1.5mm-2mm. If the design is too large, the parts inside the lamp will be visible and the appearance will be poor; the design dimension of the third gap 93 is usually >10mm. If it is too small, it will result in a poor appearance of the lamp and poor airflow inside the lamp; the gap between the inner mask 4 and the liner frame 3 of the present invention is 0mm, because the two are double-shot injection molding and zero sticking; the design dimensions of the fourth gap 94 and the fifth gap 95 are generally 0.5mm, and the design dimensions of the sixth gap 96 and the seventh gap 97 are 15mm.

[0055] From the above mechanism design, it can be seen that if Figure 7 As shown, under normal conditions, since the light-emitting module 5 is arranged close to the first gap 91, the hot airflow generated by its operation, airflow 1 flows directly from the hot zone 71 to the cold zone 72, and then flows out of the lamp from the air inlet and outlet 11; airflow 2 flows into the outer chamber 6 through the first gap 91, and then flows into the cold zone 72 from the second gap 92, and finally flows out of the lamp from the air inlet and outlet 11. However, because the first gap 91 and the second gap 92 are relatively small in size, the circulation of airflow 1 and airflow 2 is not smooth, resulting in slow exchange of circulation inside and outside the lamp, and the speed of mist dissipation is very slow.

[0056] like Figure 8As shown, in the defog state, the opening and closing mechanism 8 is started to open the breathing hole 31, and the gap between the breathing cover 81 and the breathing hole 31 is increased, that is, the fourth gap 94 and the fifth gap 95 are respectively changed into the sixth gap 96 and the seventh gap 97, thereby strengthening the flow of air in the lamp. At this time, the airflow 3 flows directly from the hot zone 71 to the cold zone 72, and then flows out of the lamp from the air inlet and outlet 11; the airflow 4 flows into the outer chamber 6 through the first gap 91, and then flows into the cold zone 72 from the second gap 92, and finally flows out of the lamp from the air inlet and outlet 11; the airflow 5 and the airflow 6 flow into the outer chamber 6 through the sixth gap 96 and the seventh gap 97 and merge with the airflow 4, and then flow into the cold zone 72 from the second gap 92, and finally flow out of the lamp from the air inlet and outlet 11; and the air inlet and outlet 11 is set on the side of the breathing hole 31 away from the inner mask 4, so as to avoid the hot airflow from the second gap 92 to the air inlet and outlet 11. Interference with the airflow 5 and the airflow 6 flowing to the breathing hole 31. As time goes by, the mist on the outer cover 2 gradually dissipates. Figure 8-11 shown.

[0057] In one embodiment:

[0058] A vehicle comprises a defogger lamp and a voice interaction device, wherein the voice interaction device comprises a voice collection module, a recognition module, a command sending module and a control module.

[0059] The voice collection module is used to obtain the user's voice information collected by the vehicle microphone when entering the monitoring mode;

[0060] The recognition module is used to recognize the voice information and determine whether there is a microphone trigger instruction corresponding to the recognition result of the voice information from the pre-acquired microphone state library according to the recognition result of the voice information; wherein the microphone trigger instruction includes the permission to open the breathing hole 31 and the permission to close the breathing hole 31;

[0061] The instruction sending module is used to send the microphone trigger instruction to the control module when there is a corresponding microphone trigger instruction, so as to control the opening and closing mechanism 8 to perform the operation of opening the breathing hole 31 authority or closing the breathing hole 31 authority.

[0062] From the above design, it can be seen that the occupants can directly give voice commands for defogger. After the defogger mode of the lamp is turned on, the travel power mechanism 83 inside the lamp will transmit power to the travel push rod 82, thereby pushing out the breathing cover 81, increasing the gap between the breathing cover 81 and the breathing hole 31, and thereby enhancing the flow of air in the lamp. When the fog in the lamp has dissipated, the defogger can be turned off by voice, and the travel power mechanism 83 will transmit power to the travel push rod 82, thereby retracting the breathing cover 81 to its initial position.

[0063] The specific structure, working principle and possible control methods of the voice acquisition module, recognition module, instruction sending module and control module described in the present invention can be selected conventionally in the art and should not be regarded as the innovative point of the present invention. It is understandable to those skilled in the art and the present invention will not be further elaborated.

[0064] According to the description and drawings of the present invention, those skilled in the art can easily manufacture or use a defogger lamp and a vehicle having the same of the present invention, and can produce the positive effects described in the present invention.
