Description

Technical Field

[0001] This utility model relates to the field of vehicle component technology, and in particular to a speaker assembly, a roof structure, and a vehicle. Background Technology

[0002] To meet the audio requirements of vehicle cabins, some models have speakers installed in the headliner. Currently, the common installation structure for this type of design is a combination of speaker and cover. During installation, the speaker is first installed on the cover, and then the cover is snapped into the speaker mounting holes in the headliner. However, when using this structure to install speakers, during the deployment of side curtain airbags, the speaker and cover are easily pushed out and detached. If this headliner structure is used for side curtain airbag deployment tests, it will significantly increase the testing cost. Utility Model Content

[0003] The main purpose of this utility model is to propose a speaker assembly, a roof structure, and a vehicle, which aims to solve the technical problem that speakers installed on the roof are prone to falling off during the side curtain air blast.

[0004] To achieve the above objectives, this utility model proposes a speaker assembly, installed on the headliner of a vehicle, comprising:

[0005] The bracket includes a mounting hole and an overlapping part, the overlapping part enclosing the mounting hole, the ceiling liner having a receiving hole corresponding to the mounting hole, the overlapping part being installed on the ceiling liner, and the bottom surface of the overlapping part being in contact with the top surface of the ceiling liner;

[0006] A loudspeaker, the loudspeaker including at least two mounting plates, the bracket including at least two connecting portions connected to the mounting portions, the mounting plates being connected to the connecting portions, and the bottom surface of the mounting plates being in contact with the top surface of the connecting portions, the loudspeaker being supported on the connecting portions by the mounting plates, and the loudspeaker passing through the mounting hole and the receiving hole.

[0007] In one embodiment, the length of the receiving hole is defined as L, and the overlap between the overlapping portion and the ceiling liner is defined as L1.

[0008] Then, L and L1 satisfy: L1≥0.1L.

[0009] In one embodiment, the connecting portion has a first fixing hole, the loudspeaker further includes a fixing member, an outer frame and a sound-emitting member mounted on the outer frame, at least two mounting plates are installed at intervals on the outer periphery of the outer frame, the mounting plates have a second fixing hole, the second fixing hole is provided in a one-to-one correspondence with the first fixing hole, and the fixing member passes through the first fixing hole and the second fixing hole.

[0010] In one embodiment, the speaker assembly further includes a decorative cover mounted on the overlap portion and covering the receiving hole on the side away from the overlap portion.

[0011] In one embodiment, the decorative cover includes a cover body, a limiting part, and a buckle, wherein the limiting part and the buckle are both installed on the side of the cover body facing the receiving hole;

[0012] The bracket also includes a limiting piece and a snap-fit ​​protrusion. The limiting piece is installed on the overlapping part and has a limiting hole. The limiting part passes through the limiting hole. The snap-fit ​​protrusion protrudes from the inner wall of the mounting hole and snaps into the snap-fit ​​protrusion.

[0013] In one embodiment, there are at least two buckles and at least two snap-fit ​​protrusions. At least two buckles are installed at intervals on the side of the cover facing the receiving hole, and at least two snap-fit ​​protrusions are disposed at intervals on the inner wall of the mounting hole. The snap-fit ​​protrusions correspond one-to-one with the buckles.

[0014] In one embodiment, the cover includes a plurality of sound outlets, which are disposed corresponding to the diaphragm of the loudspeaker.

[0015] In one embodiment, the bracket is a one-piece molded part.

[0016] This utility model also proposes a ceiling structure, including the speaker assembly described in any of the above embodiments.

[0017] This utility model also proposes a vehicle including the roof structure described in the previous embodiment.

[0018] According to the technical solution of this utility model, a speaker assembly is installed on the headliner of a vehicle. It includes a bracket and a speaker. The bracket includes a mounting hole and an overlapping portion, the overlapping portion forming the mounting hole. The headliner has a receiving hole corresponding to the mounting hole. The overlapping portion is installed on the headliner, and its bottom surface is flush with the top surface of the headliner. The speaker includes at least two mounting plates, and the bracket also includes at least two connecting portions connected to the overlapping portion for connecting with the mounting plates. The bottom surface of the mounting plate is flush with the top surface of the connecting portion. The speaker can be supported by the mounting plates on the connecting portions. The speaker passes through the mounting hole and the receiving hole. This arrangement allows the bracket to be installed between the headliner and the headliner sheet metal, and the overlapping portion of the bracket can be flush with the top surface of the headliner. Thus, during the deployment of the side curtain airbag, even if the side curtain airbag applies an impact force to the speaker assembly, the impact force will be dispersed to the headliner through the speaker and the overlapping portion. The overlapping section fits snugly against the ceiling lining around the receiving hole, making the planar area of ​​the bracket larger than the area of ​​the receiving hole. This prevents the bracket from being squeezed out of the receiving hole and falling due to the side air curtain. Similarly, by attaching the speaker to the bracket via the overlapping plate, it also prevents the speaker itself from being squeezed out of the mounting hole and falling due to the side air curtain. Therefore, through this design, the probability of the speaker assembly being squeezed out of the ceiling lining and falling off during the side air curtain burst is reduced, thus solving the problem of the speaker assembly easily detaching due to the pressure of the side air curtain.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0038] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0039] In the automotive industry, the sound quality within a vehicle's cabin has become a crucial indicator of overall vehicle quality. To meet consumer demand for high-quality audio, some models install speakers in the headliner to enhance the in-car sound experience. Currently, the mainstream installation method involves combining the speaker with a trim cover. The specific installation process is as follows: first, the speaker is installed inside the trim cover, ensuring a tight connection; then, the trim cover with the speaker is snapped into the pre-drilled speaker mounting holes in the headliner, completing the final assembly. This design ensures both excellent sound output and aesthetic appeal and practicality of the interior.

[0040] However, in practical applications, this speaker and trim combination also presents certain problems. For example, in the critical moment when a vehicle collision occurs and the side curtain airbags need to deploy to protect occupants, the insufficient rigidity of the roof material in some models makes them prone to deformation under external impact. This deformation, under the powerful force of the side curtain airbag deployment, often causes the speakers and trim, originally securely mounted on the roof, to be pushed out and detach. This not only affects the normal deployment of the side curtain airbags, reducing their protective effect on occupants, but also inevitably increases the failure rate and number of repetitions of the test if this potentially problematic roof structure is used for side curtain airbag deployment tests, significantly increasing test costs and causing unnecessary economic losses for automakers.

[0041] In view of this, the present invention proposes a loudspeaker assembly to solve or at least alleviate the above-mentioned problems.

[0042] In one embodiment of this utility model, please refer to Figure 2 The speaker assembly 100 is mounted on the vehicle's headliner 200 and includes a bracket 1 and a speaker 2, wherein, please refer to... Figure 1 , Figure 3 and Figure 4The bracket 1 includes a mounting hole 11 and an overlapping portion 12. The overlapping portion 12 surrounds and forms the mounting hole 11. The ceiling liner 200 has a receiving hole 210, which corresponds to the mounting hole 11. The overlapping portion 12 is installed on the ceiling liner 200, and the bottom surface of the overlapping portion 12 is in contact with the top surface of the ceiling liner 200. Please refer to [link / reference]. Figures 4 to 8 The speaker 2 includes at least two mounting plates 21, and the bracket 1 also includes at least two connecting parts 13 connected to the mounting plate 21. The bottom surface of the mounting plate 21 is in contact with the top surface of the connecting part 13. The speaker 2 can be supported on the connecting part 13 through the mounting plate 21. The speaker 2 passes through the mounting hole 11 and the receiving hole 210.

[0043] Specifically, the ceiling liner 200 is installed on the inner side of the ceiling sheet metal, that is, the side of the ceiling sheet metal facing the interior of the cabin. There is a certain gap between the ceiling liner 200 and the ceiling sheet metal to accommodate the installation of side air curtains, wiring, reading lights, and speaker assemblies 100, etc. In this embodiment, the circumferential dimensions of the mounting holes 11 are all overlapping portions 12, and the shape of the mounting holes 11 needs to be adapted to the external contour of the speaker 2 mounted thereon. During installation, the mounting plate 21 of the speaker 2 overlaps the top surface of the connecting part 13, and the mounting plate 21 is fixed to the connecting part 13. The fixing method includes either threaded connection or adhesive bonding. After the speaker 2 is fixed to the connecting part 13, the overlapping part 12 overlaps a portion of the circumferential area of ​​the receiving hole 210 of the ceiling liner 200, so that the overlapping part 12 overlaps with the ceiling liner 200. Then, glue is injected between the bottom surface of the overlapping part 12 and the top surface of the ceiling liner 200 through the glue injection hole opened in the overlapping part 12 to fix the overlapping part 12 to the ceiling liner 200. In this way, even if the ceiling liner 200 is deformed due to external force, the bracket 1 will not fall off towards the cabin interior. In this embodiment, the bracket 1 is made of rigid plastic, such as polyamide or polycarbonate, which has a certain rigidity and will not cause large deformation of the mounting hole 11 when subjected to external force, thereby reducing the probability of the speaker 2 falling off from the mounting hole 11 into the cabin interior.

[0044] According to the technical solution of this embodiment, the bracket 1 is installed between the ceiling liner 200 and the ceiling sheet metal, and the overlapping part 12 of the bracket 1 can fit against the top surface of the ceiling liner 200. In this way, during the explosion of the side air curtain, even if the side air curtain applies an impact force to the speaker assembly 100 when it unfolds, the impact force will be distributed to the ceiling liner 200 through the transmission of the speaker 2 and the overlapping part 12, avoiding the concentration of force on the ceiling liner 200, which helps to reduce the deformation of the ceiling liner 200, thereby preventing excessive deformation of the receiving hole 210. The overlapping part 12 fits against the ceiling liner 200 around the receiving hole 210, making the plane area of ​​the bracket 1 larger than the area of ​​the receiving hole 210, thereby preventing the bracket 1 from being squeezed out of the receiving hole 210 by the side air curtain and falling off. By overlapping the speaker 2 with the bracket 1 through the overlapping plate 21, it is also possible to prevent the speaker 2 itself from being squeezed out of the mounting hole 11 by the side air curtain and falling off. Therefore, by setting up this solution, the probability of the speaker assembly 100 being squeezed out of the ceiling liner 200 during the side air curtain explosion is reduced, thereby solving the problem that the speaker assembly 100 is easily detached due to the compression of the side air curtain.

[0045] In one embodiment of this utility model, the length of the receiving hole 210 is defined as L, and the overlap between the overlapping portion 12 and the ceiling liner 200 is defined as L1; then, L and L1 satisfy: L1 ≥ 0.1L. For example, in this embodiment, please refer to... Figure 1 Since the planar shape of the receiving hole 210 is roughly rectangular, the minimum length of the overlap portion 12 should be calculated based on the length of this type of rectangle. Furthermore, the length of the overlap portion 12 around the mounting hole 11 should be greater than or equal to this minimum value. When determining the specific length of the overlap portion 12, the venting path of the side air curtain at the top of the ceiling liner 200 and the positions of various wiring lines should also be considered. This arrangement ensures the overlap length between the overlap portion 12 and the ceiling liner 200, thereby helping to prevent the bracket 1 from detaching from the receiving hole 210.

[0046] In one embodiment of this utility model, please refer to Figure 4 , Figure 8 and Figure 9The connecting part 13 has a first fixing hole 131. The speaker 2 also includes a fixing member 24, an outer frame 22, and a sound-emitting element 23 mounted on the outer frame 22. At least two mounting plates 21 are spaced apart and installed on the outer periphery of the outer frame 22. The mounting plates 21 have a second fixing hole 211, which corresponds to the first fixing hole 131. The fixing member 24 passes through the first fixing hole 131 and the second fixing hole 211. The fixing member 24 includes either a screw or a bolt. The sound-emitting element 23 is snapped onto the outer frame 22. Four mounting plates 21 are circumferentially connected to the outer frame 22, and all four mounting plates 21 are in the same plane. The mounting plates 21 are connected to the connecting part 13 by the fixing member 24 passing through the first fixing hole 131 and the second fixing hole 211. The use of screws or bolts ensures a stable connection between the mounting plates 21 and the connecting part 13, and also improves the convenience of subsequent disassembly and maintenance of the speaker 2.

[0047] In one embodiment of this utility model, please refer to Figures 4 to 8 The speaker assembly 100 also includes a decorative cover 3, which is mounted on the overlap 12 and covers the side of the receiving hole 210 away from the overlap 12. The decorative cover 3 is directly visible to the occupants inside the cabin, enhancing the cabin's aesthetics. Furthermore, the bottom surface of the decorative cover 3 is flush with the bottom surface of the ceiling liner 200, thus avoiding encroachment on cabin space.

[0048] In one embodiment of this utility model, please refer to Figure 3 , Figure 4 and Figure 9 The decorative cover 3 includes a cover body 31, a limiting part 32, and a buckle 33. Both the limiting part 32 and the buckle 33 are installed on the side of the cover body 31 facing the receiving hole 210. The bracket 1 also includes a limiting piece 14 and a snap-fit ​​protrusion 15. The limiting piece 14 is installed on the overlapping part 12 and has a limiting hole 141. The limiting part 32 passes through the limiting hole 141. The snap-fit ​​protrusion 15 protrudes from the inner wall of the mounting hole 11, and the buckle 33 snaps into the snap-fit ​​protrusion 15. The limiting part 32 is groove-shaped, and its side abuts against the inner wall of the limiting hole 141 to restrict the movement of the cover body 31. Furthermore, the length of the limiting part 32 is greater than the length of the buckle 33. During installation of the decorative cover 3, the limiting part 32 first extends into the limiting hole 141 to provide guidance, thereby improving the installation efficiency of the decorative cover 3. The top of the buckle 33 is provided with a reverse buckle structure, which cooperates with the snap-fit ​​protrusion 15 to complete the snap-fit ​​between the decorative cover 3 and the bracket 1. Since the decorative cover 3 is directly exposed in the vehicle's cabin, it is a vulnerable and easily scratched part. Therefore, snapping it with the bracket 1 helps to improve the convenience of disassembling and replacing the decorative cover 3.

[0049] In one embodiment of this utility model, there are at least two buckles 33 and at least two latching protrusions 15. At least two buckles 33 are spaced apart on the side of the cover 31 facing the receiving hole 210, and at least two latching protrusions 15 are spaced apart on the inner wall of the mounting hole 11. Each latching protrusion 15 corresponds to one buckle 33. This creates a multi-point latching structure between the decorative cover 3 and the bracket 1. Multiple sets of buckles 33 and latching protrusions 15 work together to effectively prevent the decorative cover 3 from loosening or accidentally falling off. Even if one buckle 33 yields and loses its latching function, the remaining buckles 33 can still latch the decorative cover 3 to the bracket 1, thus allowing the decorative cover 3 to still perform its basic function. Furthermore, the multi-point latching arrangement disperses the stress in the cover 31 and the bracket 1, avoiding stress concentration, which helps improve durability and reduces the risk of damage to a single buckle 33.

[0050] In one embodiment of this utility model, please refer to Figure 5 The enclosure 31 includes multiple sound outlets 311, which are correspondingly arranged with the diaphragm of the speaker 2. The sound outlets 311 connect the cockpit to the receiving hole 210. Multiple sound outlets 311 allow for more even sound wave diffusion, reducing sound concentration in a specific direction and thus improving the listening experience. Furthermore, the multiple sound outlets 311 can be arranged in different shapes, providing a degree of visual distinctiveness to the enclosure 31's appearance and enhancing the overall quality of the cockpit.

[0051] In one embodiment of this utility model, the bracket 1 is a one-piece molded part. The bracket 1 is integrally molded by injection molding, and its material includes one of polyamide, polycarbonate, etc.
