DETAILED DESCRIPTION

[0014] In order to enable those skilled in the art to understand the present disclosure more clearly, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present disclosure.

[0015] Smart interactive displays and illuminated grilles are representative of products utilizing electronics and software.

Upon receiving a signal, the illuminated grille can display a variety of patterns, allowing the driver to communicate with the outside world. With increasing customer demand for personalized features, more options are needed, a feature currently unavailable on grilles.

[0016] To this end, the present disclosure provides a light-emitting grille and a vehicle, which can, to a certain extent, solve the technical problem that the light-emitting grille only has a light-emitting effect and a single function.

[0017] FIG1 is a schematic diagram of the structure of a light-emitting grille according to one or more embodiments of the present disclosure, FIG2 is a rear view of the light-emitting grille of FIG1 , and FIG3 is a cross-sectional view of the light-emitting grille of FIG1 with a speaker. As shown in FIG1 , FIG2 and FIG3 , a first aspect of the present disclosure provides a light-emitting grille. The light-emitting grille 100 includes a rear housing 110, a light-transmitting mask 120, a light-emitting assembly 130, and a speaker 140. In some embodiments, the light-transmitting mask 120 is connected to the rear housing 110, and the light-transmitting mask 120 and the rear housing 110 together form a receiving cavity 150; the light-emitting assembly 130 is connected to the rear housing 110 and is located in the receiving cavity 150; and the speaker 140 is mounted on the light-transmitting mask 120 and is located on the same side of the light-transmitting mask 120 as the rear housing 110.

[0018] As shown in FIG3 , the back shell 110 is connected to the light-transmitting mask 120 by bonding. In order to ensure the connection strength between the back shell 110 and the light-transmitting mask 120, in some embodiments, the back shell 110 and the light-transmitting mask 120 are sealed and fixed using a two-component adhesive, for example, the two-component adhesive can be a two-component polyurethane adhesive. By sealing and fixing the back shell 110 and the light-transmitting mask 120 with a two-component adhesive, the sealing of the interior of the accommodating cavity 150 enclosed by the back shell 110 and the light-transmitting mask 120 is ensured, so that the interior of the accommodating cavity 150 enclosed by the back shell 110 and the light-transmitting mask 120 has dustproof and waterproof functions, which can prevent dust or water from entering the accommodating cavity 150 and damaging the light-emitting component 130. In addition, the light-emitting component 130 is connected to the back shell 110, and the back shell 110 provides a mounting base for the light-emitting component 130, thereby ensuring the overall strength of the light-emitting component 130.

[0019] In some embodiments, as shown in Figure 3, the light-emitting component 130 may include a light diffuser 131 and a PCB board 132. The light diffuser 131 and the PCB board 132 are arranged in the accommodating cavity 150, and the light diffuser 131 is arranged between the translucent mask 120 and the PCB board 132; the light diffuser 131 and the back shell 110 can be connected by screws; in other embodiments, the light diffuser 131 can be made of light-diffusing PC, which is also called polycarbonate light diffuser. It is a light-transmitting but opaque light-diffusing material with transparent PC plastic as the base material, PC is polycarbonate, and a certain proportion of light diffuser and other additives are added through a special process to polymerize. The light diffuser 131 mainly diffuses the light source evenly to ensure the uniformity of the brightness of the light-emitting surface. The light diffuser 131 can ensure that the light can be evenly dispersed on the translucent mask 120.

[0020] In other embodiments, as shown in FIG3 , the PCB 132 and the rear housing 110 can be connected by welding. In some embodiments, the PCB 132 can be provided with a plurality of bumps, and the PCB 132 and the rear housing 110 can be connected by spot welding. The light-transmitting mask 120 and the rear housing 110 together form a receiving cavity 150, in which the PCB 132 is located. The rear housing 110 provides a mounting base for the light-emitting assembly 130, ensuring the overall strength of the light-emitting assembly 130 while also ensuring the dust and water resistance of the PCB 132.

[0021] The speaker 140 can receive an audio signal and play the music or audio corresponding to the received audio signal. In some embodiments, as shown in Figures 2 and 3, the speaker 140 can play the music or audio corresponding to the received audio signal more clearly. In some embodiments, the played music or audio has lossless sound quality and good sound quality. In some embodiments, the speaker 140 is connected to the light-transmitting mask 120. In some embodiments, the speaker 140 can be connected and fixed to the light-transmitting mask 120 by double-sided tape or single-component tape. For example, the single-component tape can be a single-component epoxy tape. The light-transmitting mask 120 can serve as a mask for the speaker 140, which can ensure both overall strength and the sound quality of the speaker 140.

[0022] In some embodiments, as shown in Figures 2 and 3, the light-emitting grille 100 may further include a controller. In some embodiments, the speaker 140 and the light-emitting assembly 130 may be electrically connected via the controller. When the controller receives an audio signal, the signal may be transmitted to the speaker 140 and the light-emitting assembly 130. In some embodiments, the speaker 140 may be used to transmit music or audio signals, while the light-emitting assembly 130 may be used to transmit optical signals. That is, the speaker 140 and the light-emitting assembly 130 may simultaneously transmit audio and optical signals by receiving signals, thereby realizing an integrated audio and optical light-emitting grille 100 and increasing the overall entertainment value of the light-emitting grille 100. The controller may control the audio and optical signals to be consistent, thereby achieving a music and light show effect. For example, when a vehicle is unlocked or closed, a prompt may be provided via audio and optical signals. When a vehicle is driving, a reminder may be provided via audio and optical signals while crossing a zebra crossing or waiting at a traffic light.

[0023] Therefore, the accommodating cavity 150 surrounded by the rear shell 110 and the translucent mask 120 ensures the sealing of the interior of the accommodating cavity 150 surrounded by the rear shell 110 and the translucent mask 120, so that the interior of the accommodating cavity 150 surrounded by the rear shell 110 and the translucent mask 120 has dustproof and waterproof functions, and provides a mounting base for the light-emitting component 130; in addition, the speaker 140 provided on the translucent mask 120 enriches the function of the light-emitting grille 100; the rhythm of the audio and the changing frequency of the light-emitting effect of the light-emitting grille 100 can be kept consistent, that is, the sound and optoelectronic integrated signal transmission can be carried out simultaneously by receiving signals, realizing the audio and optoelectronic integrated light-emitting grille 100, and increasing the overall entertainment attributes of the light-emitting grille 100.

[0024] In some embodiments, as shown in Figure 1, the translucent mask 120 may include a light-emitting area 121 and a non-light-emitting area 122, the speaker 140 is installed in the non-light-emitting area 122, and the speaker 140 is located in the middle of the light-emitting mask 120; the position of the light-emitting component 130 corresponds to the position of the light-emitting area 121, which can ensure that the light emitted by the light-emitting component 130 can be emitted from the light-emitting area 121.

[0025] In some embodiments, as shown in FIG1 , the luminous area 121 is located in the middle of the non-luminous area 122. In some embodiments, the non-luminous area 122 is annular, with the luminous area 121 located in the middle of the annular structure. In some embodiments, the non-luminous area 122 can also be a non-annular structure, that is, the non-luminous area 122 can be partially surrounded by the luminous area 121. Specifically, the non-luminous area 122 primarily houses the speaker 140 and the rear housing 110, while the central luminous area 121 is used for light emitted by the light-emitting assembly 130 to be emitted from the luminous area 121.

[0026] To facilitate connection of the speaker 140 and the rear housing 110 to the light-transmitting mask 120, in some embodiments, as shown in Figures 1 and 3, the non-luminous area 122 may include a mounting portion 1221 and a connecting portion 1222. In some embodiments, the mounting portion 1221 is connected to the rear housing 110, and the speaker 140 is connected to the connecting portion 1222.

[0027] In some embodiments, as shown in Figures 1 and 3, mounting portion 1221 is located outside light-emitting area 121; the center of light-emitting area 121 is recessed to form a clearance zone, and connecting portion 1222 is located within the clearance zone. In this case, speaker 140 is located within the recessed center of light-emitting area 121, forming a clearance zone. This facilitates mounting speaker 140 on translucent mask 120 and prevents interference between speaker 140 and light-emitting area 121.

[0028] In some embodiments, as shown in Figures 1 and 3, the non-luminous area 122 can have a double-layer structure, while the luminous area 121 has a single-layer structure. The double-layered non-luminous area 122 can be used to connect the rear housing 110 and the speaker 140 to improve the connection strength. The single-layered luminous area 121 is mainly used to allow light emitted by the light-emitting component 130 to be emitted through the luminous area 121.

[0029] In some embodiments, the light-transmitting mask 120 is made of a light-transmitting PP material. In some embodiments, the PP material is polypropylene, which has a relatively low density. In some embodiments, the light-transmitting mask 120 is an integral injection-molded structure, ensuring that the light-transmitting mask 120 has a smooth shape.

[0030] In some embodiments, the translucent mask 120 is provided with a plurality of light-transmitting areas 123 arranged in an array; a PCB 132 is provided with a dot matrix light source, with each of the light beads in the dot matrix light source corresponding one-to-one with the light-transmitting areas 123 arranged in the array. In other embodiments, the PCB 132 can arrange LEDs according to set requirements, and by receiving upper-layer control signals, control the illumination of different LEDs, transmitting light through the light-transmitting areas 123 of the translucent mask 120, thereby achieving different patterns and / or different frequency-varying light effects.

[0031] In some embodiments, as shown in FIG1 , the light-transmitting area 123 may be shaped like at least one of a car logo, text, letters, and numbers. In some embodiments, the light-transmitting area 123 may be shaped like a car logo, and when the light-emitting grid 100 is illuminated, the light-transmitting area 123 may present several illuminated car logos.

[0032] In some embodiments, the translucent mask 120 can be painted with translucent body paint on the front and opaque primer on the back, then laser engraved with a translucent pattern, and then sprayed with protective paint to ensure overall performance. Laser engraving is a surface treatment process that uses optical principles.

[0033] In some embodiments, as shown in Figures 2 and 3, the rear housing 110 and the mounting portion 1221 are connected by adhesive bonding. In some embodiments, the rear housing 110 and the mounting portion 1221 of the light-transmitting mask 120 are sealed and fixed using a two-component adhesive, such as a two-component polyurethane adhesive. By sealing the rear housing 110 and the light-transmitting mask 120 with the two-component adhesive, the sealing of the interior of the accommodating cavity 150 enclosed by the rear housing 110 and the light-transmitting mask 120 is ensured, making the interior of the accommodating cavity 150 enclosed by the rear housing 110 and the light-transmitting mask 120 dustproof and waterproof, thereby preventing dust or water from entering the accommodating cavity 150 and damaging the light-emitting component 130. Furthermore, the light-emitting component 130 is connected to the rear housing 110, and the rear housing 110 provides a mounting base for the light-emitting component 130, ensuring the overall strength of the light-emitting component 130. In some embodiments, the mounting portion 1221 is a double-layer structure, which improves the strength of the connection between the rear housing 110 and the light-transmitting mask 120.

[0034] In some embodiments, as shown in FIG3 , the speaker 140 can be attached to the connection portion 1222 by adhesive bonding. In some embodiments, the speaker 140 can be attached to the connection portion 1222 of the light-transmitting mask 120 using double-sided tape or a single-component adhesive. For example, the single-component adhesive can be a single-component epoxy adhesive. The light-transmitting mask 120 can serve as a mask for the speaker 140, ensuring both overall strength and the sound quality of the speaker 140. In some embodiments, the connection portion 1222 is a double-layer structure to enhance the strength of the connection between the speaker 140 and the light-transmitting mask 120.

[0035] In some embodiments, the wall thickness of the light-transmitting mask 120 can be 2.8 to 3.6 mm. In some embodiments, the thickness of the light-transmitting mask 120 can be 2.8 mm, 2.9 mm, 3.05 mm, 3.12 mm, 3.4 mm, 3.5 mm, or 3.6 mm. In some embodiments, the non-luminous area 122 of the light-transmitting mask 120 is a double-layer structure, and the luminous area 121 is a single-layer structure. The wall thickness of both the single-layer structure and the double-layer structure ranges from 2.8 to 3.6 mm. In some embodiments, the thickness of the double-layer structure is greater than that of the single-layer structure. The non-luminous area 122 of the double-layer structure is mainly used to mount the rear housing 110 and the speaker 140. By connecting the rear housing 110 and the speaker 140 to the double-layer structure, the overall mounting strength is improved.
