[0022] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the drawings, not the entire structure.

[0023] In the description of this disclosure, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0024] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0025] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0026] In related technologies, the folded edge design around the cabin increases the size of the visible overhead light, affecting its refinement.

[0027] Embodiments of this disclosure provide a dome light mounting structure to reduce the size of the dome light and improve its aesthetics. Embodiments of this disclosure also provide a headliner assembly including the dome light mounting structure, and a vehicle including the headliner assembly.

[0028] As shown in Figures 1 and 2, the ceiling light mounting structure 2 includes a mounting member 21, wherein the mounting member 21 has a ceiling light receiving groove 211 with one end open, and a light-passing hole is provided in the bottom wall of the ceiling light receiving groove 211. The mounting member 21 is provided with a limiting part 23 and a snap-fit ​​part 22 at the end of the ceiling light receiving groove 211 with the opening, and the snap-fit ​​part 22 and the limiting part 23 are arranged along the circumference of the mounting member 21.

[0029] The ceiling assembly also includes a ceiling 3 and a ceiling light body 1. The ceiling 3 is provided with mounting holes, and the mounting part 21 passes through the mounting holes. One end of the ceiling light body 1 passes through the ceiling light receiving groove 211 and presses against the bottom wall of the ceiling light receiving groove 211. The ceiling light body 1 is fixed to the top wall of the ceiling 3. The snap-fit ​​part 22 snaps into the ceiling 3. The ceiling 3 is limited to the limiting part 23 and the snap-fit ​​part 22 along the axial direction of the mounting hole.

[0030] When installing the dome light onto the ceiling 3, first, the mounting part 21 is inserted through the mounting hole, and the snap-fit ​​part 22 is snapped onto the ceiling 3. The ceiling 3 is then axially confined between the limiting part 23 and the snap-fit ​​part 22 along the mounting hole, thereby installing the dome light mounting structure 2 onto the ceiling 3. Next, one end of the dome light body 1 is inserted into the dome light receiving groove 211 and pressed against the bottom wall of the groove 211. Finally, the dome light body 1 is fixed to the top wall of the ceiling 3, thus completing the installation and fixing of the dome light body 1. By using the above-described dome light mounting structure 2 to install the dome light body 1 onto the ceiling 3, no flange is needed at the end of the dome light mounting structure 2 near the bottom wall of the ceiling 3 or on the dome light body 1. This eliminates the existing overlapping structure, which helps to reduce the exposed size of the dome light and improve its refinement. It should be noted that the exposed size of the dome light refers to the size of the dome light that can be observed by passengers inside the vehicle after it is put into use.

[0031] The main body 1 of the ceiling light is installed on the ceiling light mounting structure 2. After the main body 1 of the ceiling light is lit, the light emitted by the main body 1 of the ceiling light can radiate downward through the light-passing hole.

[0032] The ceiling assembly uses the aforementioned ceiling light mounting structure 2 to install the ceiling light body 1 onto the ceiling 3, eliminating the existing overlapping structure and improving the overall aesthetics of the ceiling 3.

[0033] The use of the aforementioned roof assembly in some of the vehicles helps to improve the overall aesthetics of the interior.

[0034] In some embodiments, as shown in FIG2, at least two snap-fit ​​portions 22 are provided and are arranged at intervals along the circumference of the mounting member 21; a limiting portion 23 is provided between at least two adjacent snap-fit ​​portions 22. This arrangement is beneficial to improving the connection stability between the ceiling light mounting structure 2 and the ceiling 3.

[0035] In some embodiments, as shown in FIG1, the mounting member 21 is generally a rectangular frame, and correspondingly, the mounting hole is a rectangular hole that mates with the mounting member 21. The inner peripheral wall of the mounting hole and the outer peripheral wall of the mounting member 21 fit together, which can restrict the circumferential rotation of the mounting member 21 by utilizing the fit between the mounting hole and the mounting member 21; and it is also beneficial to reduce the size of the mounting member 21 along the length and width directions of the mounting hole, as well as the size of the ceiling light body 1 along the length and width directions of the mounting hole. To improve aesthetics, any adjacent two side walls of the rectangular frame are smoothly connected by a rounded chamfer structure. The rectangular frame includes two first side walls arranged opposite each other along its own length, and two second side walls arranged opposite each other along its own width direction. Both the first and second side walls are provided with a snap-fit ​​part 22, wherein the first side wall is provided with at least one snap-fit ​​part 22, and the second side wall is provided with at least two snap-fit ​​parts 22. This arrangement is beneficial to improving the connection stability between the ceiling light mounting structure 2 and the ceiling 3. For example, the first sidewall has a centrally located snap-fit ​​portion 22, and the second sidewall has three snap-fit ​​portions 22, which are spaced apart along the length of the rectangular frame.

[0036] For example, one end of the rectangular frame is folded inward to form an inner flange, and the hole enclosed by the inner flange is the aforementioned light-passing hole. The end face of the inner flange located inside the rectangular frame forms the bottom wall of the aforementioned top light receiving groove 211.

[0037] In some embodiments, as shown in FIG2, the latching portion 22 includes a connecting arm 221, one end of which is connected to the mounting member 21, and the other end is provided with a latching protrusion 222. At least one of the connecting arm 221 and the latching protrusion 222 is capable of elastic deformation. Exemplarily, the connecting arm 221 is capable of elastic deformation. As an alternative, the latching protrusion 222 may also be configured to be capable of elastic deformation, or both the connecting arm 221 and the latching protrusion 222 may be configured to be capable of elastic deformation.

[0038] When installing the ceiling light mounting structure 2 onto the ceiling 3, the upper end of the mounting part 21 is inserted into the mounting hole from bottom to top. The inner circumferential wall of the mounting hole presses against the protrusion 222, causing the connecting arm 221 to undergo elastic deformation, making it easier to insert the snap-fit ​​part 22 into the mounting hole.

[0039] For example, the locking protrusion 222 protrudes from the side of the connecting arm 221 opposite to the central axis of the mounting hole. The locking portion 22 passes through the mounting hole, and one end of the locking portion 22 protrudes from the mounting hole and presses against the top wall of the canopy 3 along the second direction. The second direction is the axial direction of the mounting hole.

[0040] When the ceiling light mounting structure 2 is installed on the ceiling 3, the upper end of the mounting part 21 is inserted into the mounting hole from bottom to top. The inner peripheral wall of the mounting hole presses against the latch 222, causing the connecting arm 221 to undergo elastic deformation. After the latch 222 passes through the mounting hole, it loses the pressing force of the inner peripheral wall of the mounting hole, and the connecting arm 221 recovers its deformation, so that the latch 222 presses against the top wall of the ceiling 3 in the second direction, thereby locking the latching part 22 onto the ceiling 3.

[0041] In some embodiments, as shown in FIG2, a stop portion 332 protrudes from the inner wall of the mounting hole, and the limiting portion 23 abuts against the stop portion 332 along a first direction. The first direction is the axial direction of the mounting hole and is opposite to the second direction.

[0042] When installing the ceiling light mounting structure 2 onto the ceiling 3, the upper end of the mounting piece 21 is pushed into the mounting hole from bottom to top until it can no longer be pushed. This indicates that the limiting part 23 is pressing against the stop part 332 in the first direction, and the ceiling light mounting structure 2 is in place. At this time, the latching protrusion 222 just passes through the mounting hole and presses against the top wall of the ceiling 3 in the second direction. Since the first and second directions are opposite, the stop part 332 and the latching protrusion 222 cooperate to limit the ceiling 3 along the axial direction of the mounting hole, indirectly limiting the ceiling light mounting structure 2 along the axial direction of the mounting hole, preventing the ceiling light mounting structure 2 from shaking along the axial direction of the mounting hole, and improving the connection stability between the ceiling light mounting structure 2 and the ceiling 3.

[0043] In some embodiments, as shown in FIG2, the roof 3 includes a fabric layer 31, a substrate layer 32, and a reinforcing bracket 33 stacked sequentially along its thickness direction. The fabric layer 31 serves to improve aesthetics and provide sound insulation and noise reduction. The substrate layer 32 provides sound insulation and noise reduction and has a certain structural strength, which helps the entire roof 3 maintain its shape. The reinforcing bracket 33 serves to improve the overall structural strength of the roof 3 and to install the roof 3 into the vehicle's sunroof system.

[0044] For example, the fabric layer 31 adopts a PET-coated PU layer structure, where PET refers to polyethylene terephthalate and PU refers to polyurethane. The substrate layer 32 adopts a PU and glass fiber layer structure, and the reinforcing bracket 33 adopts a plastic reinforcing structure to improve the structural strength of the entire ceiling 3.

[0045] It should be noted that the three-layered canopy 3, including the fabric layer 31, the substrate layer 32, and the reinforcing bracket 33, can be implemented using relevant technologies in the field, and will not be described in detail here.

[0046] In some embodiments, as shown in FIG2, a through hole is provided on the substrate layer 32, and the fabric layer 31 includes a first covering portion 311 disposed within the through hole, the inner peripheral wall of the first covering portion 311 forming the aforementioned mounting hole. By using the fabric layer 31 to cover the substrate layer 32, not only can the substrate layer 32 be prevented from being exposed, but also the edges caused by the opening in the fabric layer 31 can be prevented from being exposed.

[0047] In some embodiments, as shown in FIG2, the reinforcing bracket 33 includes a second covering portion 333, which covers the inner peripheral wall of the through hole, and a first covering portion 311 covers the inner peripheral wall of the second covering portion 333.

[0048] By using the second covering portion 333 to cover the substrate layer 32, not only is it possible to prevent the substrate layer 32 from being exposed due to the installation hole, but it also improves the structural strength of the roof 3 around the installation hole, enhances the stability of the mounting member 21 when it passes through the installation hole, and prevents the mounting member 21 from swaying in the horizontal direction. In addition, since the second covering portion 333 covers the inner peripheral wall of the through hole, it can also position the entire reinforcing bracket 33, making it easier to install the roof 3 onto the vehicle's sunroof system via the reinforcing bracket 33. By using the first covering portion 311 to cover the end of the second covering portion 333 near the bottom wall of the roof 3, the aesthetic performance can be improved.

[0049] In some embodiments, the second covering portion 333 protrudes with a stop portion 332 located within the mounting hole, and the limiting portion 23 abuts against the stop portion 332 along the axial direction of the mounting hole. By placing the stop portion 332 on the reinforcing bracket 33 with high structural strength, it is ensured that the stop portion 332 can always abut against the limiting portion 23, thereby improving the connection stability between the ceiling light mounting structure 2 and the ceiling 3.

[0050] In some embodiments, the stop portion 332 is located on one side of the first covering portion 311 along the axial direction of the mounting hole, and the stop portion 332 does not need to penetrate the first covering portion 311, simplifying the processing.

[0051] In some embodiments, as shown in FIG2, the limiting part 23 protrudes from the end face of the mounting member 21 at one end of the opening of the top light receiving groove 211, which reduces the processing requirements of the top light mounting structure 2, saves materials, and reduces costs; moreover, since the limiting part 23 is located at one end of the mounting member 21 along the axial direction of the mounting hole, the limiting part 23 is not protruding from the outer peripheral wall of the mounting member 21. Therefore, the setting of the limiting part 23 will not increase the size of the top light mounting structure 2 along the length and width directions of the rectangular frame, and will not affect the fit between the outer peripheral wall of the mounting member 21 and the inner peripheral wall of the mounting hole.

[0052] As an alternative, a limiting part 23 can be formed on the end face of the mounting member 21 located between two adjacent snap-fit ​​parts 22.

[0053] In some embodiments, as shown in FIG2, the end face of the mounting member 21 at one end of the opening of the ceiling light receiving groove 211 is provided with a deformation groove, and the snap-fit ​​part 22 is provided with deformation grooves on both sides of the mounting member 21 in the circumferential direction and at the contact position of the mounting member 21. This arrangement makes it easy for the connecting arm 221 to elastically deform during the installation of the ceiling light mounting structure 2 onto the ceiling 3, so that the snap-fit ​​protrusion 222 can pass through the mounting hole and press against the top wall of the ceiling 3 in the second direction. Exemplarily, the snap-fit ​​part 22 protrudes from the end face of the mounting member 21 at one end of the opening of the ceiling light receiving groove 211.

[0054] Among them, deformation grooves are provided on both sides of the mounting part 21 in the circumferential direction at the contact position between the snap-fit ​​part 22 and the mounting part 21.

[0055] As an alternative, a groove can be made on the end face of the mounting part 21 at one end of the opening of the top light receiving groove 211, and the snap-fit ​​part 22 can be protruded from the bottom wall of the groove. The groove penetrates the side wall of the rectangular frame in the horizontal direction. The opposite side walls of the groove and the snap-fit ​​part 22 are spaced apart, so that a deformation groove is formed between the snap-fit ​​part 22 and any one of the opposite side walls of the groove distributed in the circumference of the rectangular frame.

[0056] In some embodiments, as shown in FIG2, the ceiling light mounting structure 2 is a one-piece molded structure. This configuration simplifies the processing of the ceiling light mounting structure 2, reduces processing costs, and improves processing efficiency. Exemplarily, the ceiling light mounting structure 2 is a one-piece injection molded structure.

[0057] In some embodiments, as shown in FIG2, an annular protrusion 24 protrudes from the outer wall of the end of the mounting member 21 away from the opening of the dome light receiving slot 211. In other words, the annular protrusion 24 protrudes from the outer wall of the end of the mounting member 21 near the bottom wall of the roof 3. The inner peripheral wall of the mounting hole and the bottom wall of the roof 3 are connected by a chamfered surface, and the annular protrusion 24 abuts against the chamfered surface. This arrangement can prevent the gap between the inner peripheral wall of the mounting hole and the outer peripheral wall of the mounting member 21 from being exposed, thus avoiding affecting the aesthetic performance, and can also prevent small particles in the vehicle cabin from entering the gap between the inner peripheral wall of the mounting hole and the outer peripheral wall of the mounting member 21. Exemplarily, the chamfered surface is a rounded chamfered surface, and the surface of the annular protrusion 24 abutting against the chamfered surface is a curved surface that can fit with the rounded chamfered surface.

[0058] In some embodiments, as shown in FIG2, the end face of the mounting member 21 away from the opening of the dome light receiving groove 211 is flush with the bottom wall of the roof 3. In other words, the lowest point of the end face of the mounting member 21 away from the opening of the dome light receiving groove 211 is flush with the bottom wall of the roof 3. The end of the dome light body 1 near the bottom wall of the roof 3 is flush with the end face of the mounting member 21 away from the opening of the dome light receiving groove 211. In other words, the lowest point of the end of the dome light body 1 near the bottom wall of the roof 3 is flush with the lowest point of the end face of the mounting member 21 away from the opening of the dome light receiving groove 211. This arrangement not only avoids the dome light mounting structure 2 and the dome light body 1 occupying the space below the bottom wall of the roof 3, but also helps to ensure the flatness of the interior roof 3 and improve the overall aesthetics of the vehicle interior.

[0059] In some embodiments, as shown in FIG2, the top wall of the ceiling 3 is provided with a mounting protrusion 331, and the ceiling light body 1 is connected to the mounting protrusion 331 by fasteners 4. This arrangement facilitates placing one end of the ceiling light body 1 in the ceiling light receiving groove 211, which abuts against the bottom wall of the groove 211, thereby improving the installation stability of the ceiling light. Exemplarily, the mounting protrusion 331 protrudes from the side surface of the reinforcing bracket 33 facing away from the substrate layer 32. The mounting protrusion 331 is integrally formed into the reinforcing bracket 33, ensuring the structural strength of the mounting protrusion 331, simplifying the processing of the mounting protrusion 331, and reducing processing costs.

[0060] In some embodiments, multiple fasteners 4 are provided, and the multiple fasteners 4 are arranged at circumferential intervals along the ceiling light body 1 to improve the connection strength between the ceiling 3 and the ceiling light body 1. Exemplarily, three fasteners 4 are provided.

[0061] This disclosure has at least the following beneficial effects:

[0062] The ceiling light mounting structure disclosed herein, when installing the ceiling light onto the ceiling, first inserts the mounting component through the mounting hole, and then engages the snap-fit ​​part with the ceiling. The ceiling is then axially confined between the limiting part and the snap-fit ​​part along the mounting hole, thereby installing the ceiling light mounting structure onto the ceiling. Next, one end of the ceiling light body is inserted into the ceiling light receiving groove and pressed against the bottom wall of the groove. Finally, the ceiling light body is fixed to the top wall of the ceiling, thus completing the installation and fixing of the ceiling light body. By using the above-described ceiling light mounting structure to install the ceiling light body onto the ceiling, no flange is required at the end of the ceiling light mounting structure near the bottom wall or on the ceiling light body, eliminating the overlapping structure in related technologies. This helps to reduce the exposed size of the ceiling light and improve its overall refinement.

[0063] The ceiling assembly disclosed herein uses the aforementioned ceiling light mounting structure to install the main body of the ceiling light onto the ceiling, eliminating the overlapping structure in related technologies, which helps to improve the overall aesthetic performance of the ceiling.

[0064] The vehicle disclosed herein uses the aforementioned roof assembly, which helps to improve the overall aesthetics of the vehicle interior.

[0065] Furthermore, the above description is merely a preferred embodiment and the technical principles employed in this disclosure. Those skilled in the art will understand that this disclosure is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of this disclosure. Therefore, although this disclosure has been described in detail through the above embodiments, this disclosure is not limited to the above embodiments. Many other equivalent embodiments may be included without departing from the concept of this disclosure, and the scope of this disclosure is determined by the scope of the appended claims.
