Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to an automotive horn bracket mounting structure. Background Technology

[0002] In automotive acoustic system design, the installation location and connection method of tweeters directly affect the overall vehicle sound quality, assembly efficiency, and ease of maintenance. Traditional tweeters are mostly installed on the door trim panels, but due to limitations in sound field directivity and spatial layout, achieving ideal acoustic effects is difficult. With the increasing demand for high-quality audio systems in new car models, placing tweeters on the B-pillar trim panels has become an effective solution for optimizing acoustic performance. However, in existing structures, removing the tweeter bracket from the B-pillar trim panel requires damaging either the bracket or the panel, resulting in poor maintainability and severely restricting the maintainability and engineering application of this placement scheme. Utility Model Content

[0003] The main purpose of this invention is to propose a car horn bracket mounting structure, which aims to solve the problem of poor maintainability of horn brackets.

[0004] To achieve the above objectives, this utility model proposes a car horn bracket mounting structure, which includes:

[0005] A speaker bracket, comprising a frame body and a connector, wherein the connector is connected to the frame body and the frame body is used for detachable connection with a speaker;

[0006] B-pillar trim;

[0007] fastener;

[0008] A reinforcing bracket is located between the speaker bracket and the B-pillar trim panel. The reinforcing bracket includes a base plate and a connecting plate that are connected to each other. The base plate has a receiving groove on the side facing the speaker bracket, which is used to receive the bracket body. The connecting plate has a first connecting part and a second connecting part. The first connecting part is fixedly connected to the B-pillar trim panel, and the connecting part is detachably connected to the second connecting part through the fastener.

[0009] In one embodiment, the second connecting portion extends toward the connector to form a protrusion, the protrusion having a threaded hole, the connector having a through hole, and the fastener including a screw that passes through the through hole and is threadedly engaged with the threaded hole to restrict movement of the connector relative to the protrusion.

[0010] In one embodiment, the connector includes a connecting arm and a connecting ear. One end of the connecting arm is connected to the side of the frame body away from the B-pillar trim panel, and the other end of the connecting arm extends out of the receiving groove and connects to the connecting ear. The connecting ear is provided with the through hole.

[0011] In one embodiment, the first connecting portion extends toward the B-pillar trim panel to form a boss, and the boss is fixedly connected to the B-pillar trim panel.

[0012] In one embodiment, the boss is provided with a flat surface, which is welded to the B-pillar trim panel.

[0013] In one embodiment, the number of the bosses is multiple, and the multiple bosses are arranged at intervals along the circumference of the base plate.

[0014] In one embodiment, the B-pillar trim panel is provided with a first positioning member and a second positioning member on the side facing the connecting plate. The connecting plate is also provided with a first positioning hole and a second positioning hole, wherein the first positioning hole is for the first positioning member to pass through and the second positioning hole is for the second positioning member to pass through.

[0015] In one embodiment, the base plate is further provided with a sound-permeable panel, which is positioned facing the sound outlet of the speaker. The sound-permeable panel is provided with a plurality of sound holes, each of which is connected to the receiving groove. The B-pillar trim panel is provided with a trim panel sound window, which is positioned facing the sound-permeable panel.

[0016] In one embodiment, the frame body is provided with a mounting opening and a snap-fit ​​groove, the mounting opening is used to accommodate at least a portion of the structure of the speaker, and the snap-fit ​​groove is used to engage with the clips on the speaker.

[0017] And / or,

[0018] The connecting plate is also provided with a buckle, which is used to connect with the rib reinforcement.

[0019] In one embodiment, there are multiple connectors, which are arranged at intervals along the circumference of the frame body. The number of second connecting parts is the same as the number of connectors and they are set in a one-to-one correspondence. The number of fasteners is the same as the number of connectors and they are set in a one-to-one correspondence.

[0020] In this embodiment of the invention, the car horn bracket mounting structure uses a reinforcing bracket as an intermediate transition piece, which is fixed to the B-pillar trim panel. The horn bracket is then installed onto the reinforcing bracket using fasteners, fundamentally solving the problems of poor maintainability and high production costs caused by traditional hot-melt welding processes. Specifically, the reinforcing bracket is located between the horn bracket and the B-pillar trim panel. Its base plate has a receiving groove on the side facing the horn bracket, which can effectively position and limit the frame body of the horn bracket, improving assembly accuracy and enhancing connection stability. The reinforcing bracket is fixedly connected to the B-pillar trim panel through a first connecting part, forming a solid load-bearing foundation. On this basis, the second connecting part on the connecting plate and the connecting piece of the horn bracket are detachably connected by screws and other fasteners. This design abandons the traditional integrated connection method that relies on high-temperature melting and molding, allowing the horn bracket to be disassembled and assembled without damaging the bracket body or the B-pillar trim panel. It completely solves the problem in the prior art where hot-melt welding requires cutting or prying during maintenance, resulting in parts that cannot be reused, significantly improving maintenance convenience and after-sales maintenance efficiency. Meanwhile, this detachable connection method features a simple structure and convenient operation, eliminating the need for specialized hot-melt welding equipment, precision fixtures, and complex process parameter control. This significantly reduces equipment investment, energy consumption, and production cycle time, effectively saving on production line construction and operating costs. The overall structure not only enables component reuse and reduces resource waste but also balances high reliability and assembly flexibility, achieving a comprehensive technical effect of simple structure, easy installation and disassembly, good maintainability, and cost savings. This fully aligns with modern automotive design trends towards low cost, modularity, and high maintainability. This embodiment of the invention uses a reinforcing bracket as an intermediate connector and fasteners to achieve a detachable connection between the horn bracket and the reinforcing bracket, completely abandoning the traditional hot-melt welding process. This not only solves the poor maintainability problem caused by integrated connections but also enables non-destructive disassembly and reassembly of the bracket and trim panel, significantly improving maintenance convenience. Simultaneously, it eliminates the need for specialized welding equipment and complex processes, reducing equipment investment and production costs. The overall structure is simple, assembly and disassembly are convenient, and it combines high reliability and low cost, effectively meeting the design requirements of modularity, easy maintenance, and cost reduction and efficiency improvement for automotive parts.

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 scope of protection of the present utility model.

[0035] In automotive acoustic system design, the installation location and connection method of tweeters directly affect the overall vehicle sound quality, assembly efficiency, and ease of maintenance. Traditional tweeters are mostly installed on the door trim panels, but due to limitations in sound field directivity and spatial layout, achieving ideal acoustic effects is difficult. With the increasing demand for high-quality audio systems in new car models, placing tweeters on the B-pillar trim panels has become an effective solution for optimizing acoustic performance. However, in existing structures, removing the tweeter bracket from the B-pillar trim panel requires damaging either the bracket or the panel, resulting in poor maintainability and severely restricting the maintainability and engineering application of this placement scheme.

[0036] After careful study, the applicant discovered that in existing technologies, horn brackets are typically fixed directly to the B-pillar trim panel via thermal fusion. This process involves locally melting the material at high temperatures and then cooling it to form an integrated connection structure. While this method ensures initial installation strength, it prevents non-destructive disassembly after connection. If replacement or repair of the horn is needed, destructive methods such as cutting and prying must be employed, rendering the bracket and trim panel unusable and significantly reducing maintenance convenience. Furthermore, this process relies on specialized welding equipment, precision positioning fixtures, and stable parameter control, resulting in high equipment investment, high energy consumption, and long cycle times, increasing production line construction and operating costs and failing to meet the design trends of modern automobiles towards low cost, modularity, and ease of maintenance.

[0037] Please see Figures 1 to 3In one embodiment of this utility model, the car horn bracket mounting structure 100 includes a horn bracket 1, a B-pillar trim panel 2, a reinforcing bracket 3, and fasteners 4. The horn bracket 1 includes a frame body 11 and a connector 12. The connector 12 is connected to the frame body 11, and the frame body 11 is used for detachable connection with the horn. The reinforcing bracket 3 is located between the horn bracket 1 and the B-pillar trim panel 2. The reinforcing bracket 3 includes a base plate 31 and a connecting plate 32 connected to each other. The base plate 31 is provided with a receiving groove 311 on the side facing the horn bracket 1. The receiving groove 311 is used to receive the frame body 11. The connecting plate 32 is provided with a first connecting part 321 and a second connecting part 322. The first connecting part 321 is fixedly connected to the B-pillar trim panel 2, and the connector 12 is detachably connected to the second connecting part 322 through the fasteners 4.

[0038] In this embodiment of the utility model, the car horn bracket mounting structure 100 uses a reinforcing bracket 3 as an intermediate transition piece to fix it to the B-pillar trim panel 2, and then the horn bracket 1 is installed on the reinforcing bracket 3 using fasteners 4. This fundamentally solves the problems of poor maintainability and high production costs caused by traditional hot-melt welding processes. Specifically, the reinforcing bracket 3 is located between the horn bracket 1 and the B-pillar trim panel 2. Its base plate 31 has a receiving groove 311 on the side facing the horn bracket 1, which can effectively position and limit the frame body 11 of the horn bracket 1, improving assembly accuracy and enhancing connection stability. The reinforcing bracket 3 is fixedly connected to the B-pillar trim panel 2 through the first connecting part 321, forming a solid load-bearing foundation. On this basis, the second connecting part 322 on the connecting plate 32 is detachably connected to the connecting piece 12 of the horn bracket 1 using fasteners 4. This design abandons the traditional integrated connection method that relies on high-temperature melting and molding, allowing the speaker bracket 1 to be disassembled and reassembled without damaging the bracket body 11 or the B-pillar trim panel 2. This completely solves the problem in existing technologies where heat fusion requires cutting or prying during repairs, resulting in parts that cannot be reused, significantly improving repair convenience and after-sales maintenance efficiency. Simultaneously, this detachable connection method is simple in structure and easy to operate, eliminating the need for specialized heat fusion equipment, precision fixtures, and complex process parameter control, greatly reducing equipment investment, energy consumption, and production cycle time, effectively saving on production line construction and operating costs. The overall structure not only enables the reuse of parts and reduces resource waste, but also balances high reliability and assembly flexibility, truly achieving a comprehensive technical effect of simple structure, easy installation and disassembly, good maintainability, and cost savings, fully conforming to the modern automotive design trend of low cost, modularity, and high maintainability.

[0039] The technical solution of this utility model adopts a reinforcing bracket 3 as an intermediate connecting part 12, and uses fasteners 4 to achieve a detachable connection between the speaker bracket 1 and the reinforcing bracket 3. This completely eliminates the traditional hot-melt welding process, not only solving the problem of poor maintainability caused by integrated connection, but also enabling non-destructive disassembly and assembly of the bracket and trim panel and reuse of parts, significantly improving maintenance convenience; at the same time, it eliminates the need for special welding equipment and complex processes, reducing equipment investment and production costs. The overall structure is simple, assembly and disassembly are convenient, and it has the advantages of high reliability and low cost, effectively meeting the design requirements of modularization, easy maintenance, and cost reduction and efficiency improvement of automotive parts.

[0040] Please see Figures 2 to 4 In one embodiment, the second connecting portion 322 extends towards the connector 12 to form a protrusion 3221. The protrusion 3221 has a threaded hole 32211, and the connector 12 has a through hole 1221. The fastener 4 includes a screw 41, which passes through the through hole 1221 and is threaded into the threaded hole 32211 to restrict the movement of the connector 12 relative to the protrusion 3221. Specifically, this structure uses a screw 41 as the fastener 4, which has the advantages of small size and compact structure. It can effectively adapt to the narrow installation environment of the B-pillar area, minimizing interference with surrounding wiring harnesses, trim structures, and speakers, and facilitating highly integrated modular design. Simultaneously, the screw 41 has high connection strength and good vibration resistance. The reliability and consistency of the connection can be ensured by controlling the tightening torque, avoiding abnormal noise or functional failure due to loosening. Furthermore, screw 41 is a standard part, which is low in cost and has a stable supply. The disassembly and assembly process can be completed with only conventional tools, making the operation simple. It supports non-destructive disassembly and reuse of parts, significantly improving maintenance convenience and after-sales efficiency. This solution, while ensuring a highly reliable connection, also takes into account space utilization, cost control, and maintainability, making it the preferred technical path for achieving detachable installation of the speaker bracket 1.

[0041] According to one embodiment of the present invention, the fastener 4 may be a bolt and nut or a quick-release pin, thereby realizing a detachable connection between the connector 12 and the second connecting part 322.

[0042] Please see Figures 2 to 4In one embodiment, the connector 12 includes a connecting arm 121 and a connecting ear 122. One end of the connecting arm 121 is connected to the side of the frame body 11 away from the B-pillar trim 2, and the other end of the connecting arm 121 extends out of the receiving groove 311 and connects to the connecting ear 122. The connecting ear 122 is provided with a through hole 1221. Specifically, this structure, through the extended design of the connecting arm 121, allows the connecting ear 122 to be located outside the reinforcing bracket 3 for easy assembly, avoiding blind installation within the space-constrained receiving groove 311, and significantly improving assembly convenience. At the same time, the cantilever structure formed by the connecting arm 121 and the connecting ear 122 effectively transmits and distributes the connection load, enhancing the overall connection stability and vibration resistance. When the speaker needs to be repaired or replaced, the speaker bracket 1 can be removed entirely by simply removing the screws 41, without damaging the B-pillar trim 2 or the reinforcing bracket 3, achieving non-destructive disassembly and reusability of parts, greatly improving maintainability and reducing maintenance costs. This design is reasonable, simple, and reliable, which is conducive to the modular installation and efficient maintenance of the car audio system.

[0043] Please see Figure 2 , Figure 3 and Figure 5 In one embodiment, the first connecting portion 321 extends towards the B-pillar trim 2 to form a boss 3211, which is fixedly connected to the B-pillar trim 2. Specifically, this structural design has significant process advantages: First, as a locally protruding structure, the boss 3211 can clearly and intuitively define the position of the welding area, making it easy for welding equipment or operators to identify and position during assembly, effectively avoiding welding deviation or misalignment, and improving welding accuracy and consistency. Second, the boss 3211 concentrates the welding area in a specific small area, and only the flatness and dimensional accuracy of the surface of the boss 3211 need to be controlled to ensure welding quality, greatly reducing the difficulty of process control and manufacturing costs. In contrast, if the entire plane of the connecting plate 32 is directly welded to the B-pillar trim 2, the flatness, parallelism, and surface quality of the connecting plate 32 must be strictly controlled, which not only increases the cost of mold processing and inspection, but also makes it more susceptible to factors such as injection molding deformation and temperature changes due to the large area, resulting in unstable welding quality. Therefore, by setting the boss 3211, a firm connection between the reinforcing bracket 3 and the B-pillar trim panel 2 is achieved, the welding process is optimized, the assembly efficiency and product consistency are improved, and it is conducive to achieving high reliability and low cost mass production.

[0044] Please see Figure 2 , Figure 3 and Figure 5In one embodiment, the boss 3211 is provided with a flat surface 32111, which is welded to the B-pillar trim panel 2. Specifically, the flat surface 32111 is a flat contact surface with a certain area, used to form surface contact with the B-pillar trim panel 2, rather than point contact or line contact. This surface contact structure can significantly increase the bonding area of ​​the connection region, making the pressure and heat distribution during the welding process more uniform, effectively improving welding strength, sealing performance and fatigue resistance, and avoiding cracking or desoldering problems caused by local stress concentration. At the same time, surface contact has better tolerance for assembly errors, which helps to improve the stability and consistency of the welding process. More importantly, welding reliability can be guaranteed by only controlling the dimensional accuracy and surface quality of the local flat surface 32111, without the need for high-precision control of the entire connecting plate 32 or a large area of ​​the trim panel, thereby reducing the difficulty of mold manufacturing and production costs. This design not only strengthens the connection durability between the reinforcing bracket 3 and the B-pillar trim panel 2, but also optimizes the process feasibility, which is conducive to achieving high-quality, large-scale stable assembly. The boss 3211 can be fixedly connected to the B-pillar trim panel 2 by ultrasonic welding, thereby improving the reliability of the connection.

[0045] Please see Figure 2 and Figure 3 In one embodiment, there are multiple bosses 3211, which are arranged at intervals along the circumference of the base plate 31. Specifically, in this embodiment, there are five bosses 3211. This multi-point distribution structure can evenly distribute the connection load between the reinforcing bracket 3 and the B-pillar trim 2 to multiple positions, effectively improving the stability and overall rigidity of the connection and avoiding deformation, cracking, or welding failure caused by local stress concentration. At the same time, the multiple bosses 3211 are arranged at intervals along the circumference to form a ring-shaped fixed layout, which significantly enhances the torsional and shear resistance of the reinforcing bracket 3 under complex working conditions such as vibration and impact, ensuring that it maintains a reliable connection during long-term vehicle use. In addition, the multi-point interval arrangement is conducive to balancing the stress distribution during the assembly process, improving the melting uniformity during ultrasonic welding or hot fusion, and improving the consistency of welding quality. Compared with single-point or few-point connections, this design significantly optimizes structural durability and process reliability without significantly increasing material costs, providing a more stable installation foundation for the speaker bracket 1. The layout of each boss 3211 can be reasonably adjusted according to the outer contour of the frame body 11, and its number, position and arrangement are not limited in this embodiment.

[0046] Please see Figure 2 , Figure 3 and Figure 6In one embodiment, a first positioning member 21 and a second positioning member 22 are provided on the side of the B-pillar trim panel 2 facing the connecting plate 32. The connecting plate 32 is also provided with a first positioning hole 323 and a second positioning hole 324. The first positioning hole 323 is used for the first positioning member 21 to pass through, and the second positioning hole 324 is used for the second positioning member 22 to pass through. Specifically, this dual positioning structure achieves precise positioning and error-proof assembly between the reinforcing bracket 3 and the B-pillar trim panel 2 through the cooperation of two spatially distributed positioning members and positioning holes. The cooperation of the first positioning member 21 and the first positioning hole 323 is used to determine the initial installation position of the connecting plate 32, while the cooperation of the second positioning member 22 and the second positioning hole 324 further restricts its circumferential or lateral degrees of freedom, effectively preventing rotation or offset during assembly, ensuring that the reinforcing bracket 3 maintains the correct posture during welding or fixing. This not only improves assembly accuracy and consistency but also reduces reliance on manual operation experience, which is conducive to improving the efficiency and yield of automated assembly. Meanwhile, the insertion of the positioning component and the positioning hole can be completed before welding, providing temporary fixation and preventing connection failure due to displacement during welding. This positioning structure is simple and reliable, achieving high-precision assembly without additional tooling, and providing a stable foundation for the subsequent modular installation of the speaker bracket 1. The specific shapes of the positioning component and the positioning hole can be cylindrical, conical, or irregular; this embodiment does not limit their specific structure.

[0047] Please see Figure 2 and Figure 3In one embodiment, a sound-permeable panel 312 is also provided on the base plate 31, the sound-permeable panel 312 is positioned facing the sound outlet of the speaker, and a plurality of sound holes 3121 are provided on the sound-permeable panel 3121, each of the sound holes 3121 being connected to the receiving groove 311; a panel sound window 23 is provided on the B-pillar trim panel 2, the panel sound window 23 being positioned facing the sound-permeable panel 312; specifically, the sound-permeable panel 312 is positioned facing the sound outlet of the speaker, and a plurality of sound holes 3121 are distributed on it, each of the sound holes 3121 being connected to the receiving groove 311 to form a sound propagation channel, and a panel sound window 23 is provided on the B-pillar trim panel 2 at a position corresponding to the sound-permeable panel 312, so that sound waves can be smoothly transmitted through the receiving groove 311, the sound holes 3121 and the panel sound window 23 in sequence. This structure integrates a sound-permeable panel 312 and sound holes 3121 onto the reinforcing bracket 3, achieving a rational guidance of the speaker's sound output path and effectively avoiding acoustic attenuation or sound quality distortion problems caused by bracket obstruction in traditional structures. Multiple sound holes 3121 are evenly distributed on the sound-permeable panel 312, maintaining structural strength while ensuring sufficient sound-permeable area, balancing acoustic performance and mechanical reliability. The sound-permeable panel 312 is connected to the receiving groove 311, ensuring that the sound emitted by the speaker can be transmitted directly without detours, reducing acoustic impedance and improving high-frequency clarity. The trim panel sound window 23 and the sound-permeable panel 312 are positioned opposite each other, forming a continuous acoustic channel, preventing misalignment or obstruction from affecting the sound output effect. This design incorporates acoustic considerations into the structural layout, eliminating the need for additional sound-guiding components, resulting in a compact and low-cost structure that does not affect the load-bearing function of the reinforcing bracket 3. It achieves synergistic optimization of structural reinforcement and acoustic performance, enhancing the listening experience of the in-vehicle audio system. The shape, number, and arrangement of the sound holes 3121, as well as the size and position of the sound windows 23 on the decorative panel, can be adjusted according to actual acoustic requirements. This embodiment does not limit these aspects.

[0048] Please see Figure 2 , Figure 3 and Figure 5In one embodiment, the frame body 11 is provided with a mounting opening 111 and a snap-fit ​​groove 112. The mounting opening 111 is used to accommodate at least part of the speaker structure, and the snap-fit ​​groove 112 is used to engage with the clips on the speaker. And / or, the connecting plate 32 is also provided with a buckle 325, which is used to connect with the rib 200. Specifically, the mounting opening 111 accommodates at least part of the speaker structure, allowing the speaker and the speaker bracket 1 to form axial limiting and radial fit, improving installation stability. The snap-fit ​​groove 112 engages with the clips on the speaker, realizing quick connection and axial fixation between the speaker and the frame body 11. Pre-positioning can be completed without additional fastening mechanisms, significantly improving assembly efficiency. This snap-fit ​​structure is easy to operate, reliable in connection, and supports non-destructive disassembly, facilitating later inspection or replacement and effectively improving maintenance convenience. The connecting plate 32 is also equipped with a buckle 325 that engages with the rib 200 to provide auxiliary positioning and circumferential limiting during the installation of the reinforcing bracket 3, preventing it from rotating or shifting, ensuring accurate welding or fixing of the first connecting part 321 and the B-pillar trim 2, and improving assembly accuracy and process stability.

[0049] Please see Figure 2 and Figure 3 In one embodiment, there are multiple connectors 12, which are arranged at intervals along the circumference of the frame body 11. The number of second connecting parts 322 is the same as the number of connectors 12 and they are set one-to-one. The number of fasteners 4 is the same as the number of connectors 12 and they are set one-to-one. Specifically, in this embodiment, there are three connectors 12. This multi-point symmetrical connection structure makes the force between the speaker bracket 1 and the reinforcing bracket 3 more uniform, effectively dispersing the assembly stress and vibration load during driving, significantly improving the stability and fatigue resistance of the connection, and avoiding deformation or loosening due to excessive local stress. The multiple connectors 12 are distributed circumferentially to form a ring-shaped fixed layout, which enhances the rigidity and torsional resistance of the overall structure, ensuring that the speaker can maintain a precise installation posture under complex working conditions, which is conducive to maintaining the stability of acoustic performance. At the same time, each connector 12 is detachably connected to the corresponding second connecting part 322 through an independent fastener 4. The force is evenly distributed during disassembly and assembly, which is convenient for operation and will not cause the bracket to tilt or be damaged due to loosening on one side first or uneven force. This design ensures high reliability while also considering assembly efficiency and ease of maintenance, supporting non-destructive disassembly and reuse of parts. The number, location, and arrangement of connection points can be flexibly adjusted according to the structural shape and strength requirements of the frame body 11. The second connection part 322 and the fastener 4 are correspondingly set. In this embodiment, their specific number and layout are not limited.

[0050] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
