Description

Technical Field

[0001] This invention belongs to the field of loudspeaker installation technology, and more specifically, relates to a loudspeaker installation assembly and a vehicle. Background Technology

[0002] Currently, vehicle entertainment features are increasingly favored by OEMs and passengers. Among these features, music performance is a crucial factor in evaluating a vehicle's capabilities. As the power of subwoofers continues to increase, the demands on the mounting structure and the rigidity of the mounting points also rise. Existing mounting structures often fail to meet the current requirements for speaker installation, particularly the static and dynamic rigidity of the mounting points, thus affecting the speaker's sound quality and consequently the passenger's driving experience. Summary of the Invention

[0003] The purpose of this invention is to provide a speaker mounting assembly and vehicle that can effectively improve the static and dynamic stiffness of the speaker mounting point, improve the sound quality of the speaker, and enhance the passenger's driving experience.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a speaker mounting assembly is provided, including an inner door panel and a mounting portion disposed on the inner door panel. The mounting portion is located at the lower front part of the inner door panel, and the mounting portion is provided with mounting holes for mounting speakers. The mounting portion protrudes from the inner door panel from top to bottom toward the central axis of the vehicle body.

[0005] In this embodiment, the inner door panel serves as the main carrier, providing mounting points for speakers and other accessories. The effective installation of speakers is achieved by setting a mounting part on the inner door panel. The mounting part is located in the lower front area of ​​the inner door panel, which meets the positional installation requirements of the speakers and also meets the rigidity requirements of the mounting point.

[0006] The inner door panel can be designed with concave and convex structures in different positions as needed. The mounting part is integrally formed with the inner door panel. On the one hand, this helps to improve the structural rigidity of the speaker mounting position, meet the installation requirements of the speaker, and thus improve the sound quality during the use of the speaker. On the other hand, it also facilitates the processing and manufacturing of the structure, thereby reducing the product manufacturing cost and assembly difficulty.

[0007] Specifically, a curved structure that is recessed from top to bottom away from the center axis of the vehicle body can be set on the inner door panel, and the panel surface of the mounting part extends in the vertical direction, so that the lower part of the mounting part gradually protrudes from the inner door panel, and the upper part of the mounting part is embedded relative to the inner door panel. The connection and transition between the two is natural and the overall integrity is strong.

[0008] As a parallel embodiment, the inner door panel can also be configured as a panel extending in the vertical direction, with the mounting part gradually protruding from the inner door panel from top to bottom, which can also achieve the effect of the above-mentioned embedded design, satisfy the overall requirements of the mounting part and the inner door panel, and thus facilitate the installation requirements of the speaker.

[0009] The aforementioned structural design of the mounting section and the inner door panel, without affecting the overall structure of the inner door panel, utilizes parametric and standardized structures to create a complete unit between the inner door panel and the mounting section. This facilitates speaker installation through mounting holes, allows force to be transmitted in different directions through the structure, resulting in a more even distribution of force channels and a more regular structural design. It meets the static and dynamic stiffness requirements of the mounting points, contributing to the assembly requirements of the speakers. This structure can serve as a universal design across multiple vehicle models, providing stability to the vehicle design.

[0010] When installing loudspeakers, the following points should be noted. First, ensure the loudspeakers are securely installed to prevent resonance and noise caused by misalignment during use, thus ensuring optimal sound quality. Flexible pads or other components should be used at the contact points between the loudspeakers and the mounting surface to provide cushioning and vibration isolation. Furthermore, for loudspeakers requiring sealing, appropriate sealing materials should be used.

[0011] In addition, the speaker's own wiring should be considered. When connecting the wires, pay attention to the correspondence of positive and negative terminals to ensure correct and secure wiring. Wiring harness clips or other components can be used to limit and fix the wiring harness at different positions, preventing vibrations and short circuits caused by collisions between the wires and the door panel. Furthermore, the wiring connections should be properly wrapped with insulating tape to prevent poor contact or short circuits.

[0012] In addition, the speaker installation location should be waterproofed. The area inside the door panel where the speaker is located should be properly waterproofed. This can be achieved by installing drainage channels or waterproof membranes to prevent rainwater or water from entering during car washes, thus avoiding short circuits or speaker damage. After speaker installation, sound testing should be performed. A trial run should be conducted to check if the speaker is working properly and if the sound quality meets expectations. If any abnormalities are found, the problem should be investigated promptly, examining both the installation structure and the speaker itself for possible causes, and then addressing them accordingly.

[0013] The speaker mounting location is set in the lower front area of ​​the door inner panel, near the door stop. The mounting holes of the mounting part form an embedded mounting for the speaker. Combined with the structure of the mounting part being embedded in the door inner panel, the structure is further strengthened, improving the reliability of the installation.

[0014] The speaker can form a more reliable connection structure with the inner door panel during installation. When the two are connected, the force is more easily transmitted to different directions through the mounting part, making the force distribution more even. The above-mentioned structural design is relatively regular and applicable to different models. It can meet various needs such as installation and force, and is easy and quick to operate. The connection performance is reliable and can meet the assembly requirements of the speaker, making it easy to ensure the sound quality of the speaker during use and improve the comfort of passengers.

[0015] The speaker mounting structure adopts a standardized design, which allows for a shorter design cycle and ensures that the vehicle project is completed on schedule or ahead of schedule, thus guaranteeing a smooth market launch and a rapid capture of market share. At the same time, this standardized design also contributes to the stability of the vehicle design, resulting in a mature and stable design structure that ensures good durability and superior performance.

[0016] In the above structure, the mounting part is located in the lower front part of the inner door panel, and tends to gradually protrude outward from the inner door panel from bottom to top, forming a structure that is approximately embedded in the inner door panel. This facilitates the integrity of the mounting part and the inner door panel, helps to improve the dynamic and static stiffness of the mounting part, thereby meeting the overall stiffness requirements of the structure, ensuring the reliable installation of the speaker, improving the sound quality of the speaker, and enhancing the passenger's driving experience.

[0017] In one possible implementation, the inner panel of the door has a recessed portion that gradually curves downwards toward the central axis of the vehicle body, and the mounting portion is integrally formed on the recessed portion, with the panel surface of the mounting portion extending in the vertical direction.

[0018] In this embodiment, the recessed portion on the inner panel of the door can provide more space for the interior of the vehicle and facilitate the design of the mounting portion. The mounting portion can adopt a plate structure along the vertical direction, which can form an effect of gradually protruding from the surface of the recessed portion from top to bottom, thereby making the upper part of the mounting portion gradually embedded into the inner panel of the door.

[0019] Specifically, an acute angle is formed between the X-axis projection of the recess and the X-axis projection of the mounting part, defined as δ. The value of δ ranges from 5° to 10°. Specifically, different angle values ​​such as 5°, 6°, 7°, 8°, 9°, and 10° can be selected. The selection of the above angle values ​​can not only meet the needs of embedded design, but also avoid excessive space occupation caused by the mounting part protruding too much from the surface of the recess, ensuring a reliable connection between the mounting part and the recess, improving the integrity between the inner panel of the door and the mounting part, and significantly improving the overall rigidity of the mounting part.

[0020] In some embodiments, the outer periphery of the mounting portion is provided with a transition portion that connects with the recessed portion, and the transition portion and the mounting portion have an included angle α, 40°≤α≤50°.

[0021] In this embodiment, a recessed portion is provided on the inner door panel. This recessed portion gradually extends downwards and outwards towards the outer side of the vehicle body, forming a structure where the mounting portion is embedded in the inner door panel. A transition portion connects the mounting portion and the recessed portion. As the transition portion extends towards the recessed portion, it gradually tilts away from the central axis of the mounting hole, making the transition between the mounting portion and the recessed portion more natural and the connection smoother, thus meeting the integrity requirements of the mounting portion and the inner door panel.

[0022] The angle formed between the transition section and the mounting section is α, which is the angle between the extension line of the Y-direction section of the transition section and the Y-direction section of the mounting section. α is 40° to 50°, and different angle values ​​such as 40°, 42°, 44°, 45°, 46°, 48°, and 50° can be selected. This helps to effectively distribute the force on the mounting section, ensure the effectiveness of the mounting section's embedding relative to the inner door panel, and make the force in each direction relatively balanced. This prevents the situation where the stiffness is high in some areas and weak in others, and avoids structural deformation of the mounting section, which would affect the reliable installation of the speaker. At the same time, the selection of the above angle also helps to simplify the processing technology and facilitates the integral stamping of the inner door panel and the mounting section.

[0023] To facilitate speaker installation and ensure smooth insertion into the mounting holes, the mounting portion protrudes outward from the inner door panel. Furthermore, the mounting portion gradually protrudes outward from the inner door panel from top to bottom, creating an embedded effect on the inner side of the door panel. This ensures effective connection between the mounting portion and the inner door panel, avoiding localized stress points caused by cylindrical boss structures, and also contributes to improving the aesthetics of the vehicle's interior.

[0024] To achieve an effective connection between the mounting section and the inner door panel, the outer periphery of the mounting section is connected to the inner door panel via a transition section. This transition section is formed by an inclined, extended peripheral wall, with an angle of 40° to 50° to allow the speaker mounting structure to be fully embedded in the mounting holes. The transition section can also be set at a 45° angle to facilitate a gradual connection between the transition section and the inner door panel. This allows for the overall sheet metal forming of the inner door panel and the mounting section, improving processing convenience and ensuring that the force on the mounting section 2 is effectively distributed to the inner door panel through the transition section, preventing excessive localized stress that could cause significant deformation and damage.

[0025] In one possible implementation, the mounting part is provided with a reinforcing flange connected to the circumferential edge of the mounting hole. The reinforcing flange bends and extends outward from the vehicle body. The X-direction projection of the reinforcing flange has an included angle β with the central axis of the mounting hole, where 3°≤β≤5°.

[0026] In this embodiment, the mounting hole is used to allow the speaker to be embedded in the door cavity formed by the mounting part, the transition part, and the inner door panel, avoiding the problem of excessive space occupation caused by the speaker being completely exposed in the mounting part, and helping to improve the overall aesthetics of the speaker mounting structure.

[0027] Specifically, the mounting hole is circular, consistent with the external structure of the speaker, which helps to achieve uniform force distribution. A reinforcing flange is provided at the edge of the mounting hole, extending away from the vehicle's central axis and gradually tilting towards the axis of the mounting hole. This effectively improves the structural strength at the edge of the mounting hole and prevents the strength of the mounting part from being weakened due to the opening of the mounting hole.

[0028] Based on this, the angle β formed between the X-axis projection of the flange and the central axis of the mounting hole is strengthened. β is selected from 3° to 5°, and different angle values ​​such as 3°, 3.5°, 4°, 4.5°, and 5° can be selected. This can effectively ensure the performance requirements of the speaker in the Y-axis during installation, improve the overall rigidity of the structure, avoid deformation and other problems, ensure the reliability of the installation, and thus help to ensure the sound quality of the speaker.

[0029] In one possible implementation, the mounting part is connected to the speaker via a connector. The mounting part has four connecting holes located on the outer periphery of the mounting hole for mounting the connector, which are arranged in a square.

[0030] In this embodiment, the speaker is connected to the mounting part via a connector. The connector extends through holes at the corners of the speaker into the connection hole, forming a reliable connection with the mounting part. Specifically, the connector can be a threaded connection or a riveted connection using bolts, screws, or anchors. To facilitate assembly, a projection-welded nut can be pre-installed in the connection hole, and the speaker is fixed to the mounting part by the cooperation of the threaded connector and the projection-welded nut.

[0031] Specifically, four connection holes are provided on the outer periphery of the mounting hole, with adjacent connection holes spaced at a 90-degree angle, forming a square distribution. This allows for effective connection between the speaker and the connecting part at different circumferential positions, ensuring reliable speaker installation. For locations with connection holes, the edge of the mounting part can be appropriately extended outwards to facilitate the placement of the connection holes and ensure the reliability of subsequent speaker installation.

[0032] In the above structure, the mounting holes are circular and the connecting holes are arranged in a square. The combination of these two different shapes makes the structure more stable and regular. The parameters can be adjusted according to different vehicle models and speaker sizes to ensure reliable installation.

[0033] In some embodiments, the mounting part is also provided with two positioning holes, each positioning hole being located between two adjacent connecting holes. The line connecting the two positioning holes is defined as L1, and the line connecting the two adjacent connecting holes is defined as L2. An included angle γ is formed between L1 and L2, where 40°≤γ≤50°.

[0034] In this embodiment, the angle and distance between adjacent mounting holes are equal, which can ensure reliable and stable force at different positions around the mounting part, making the speaker installation stable and firm, and avoiding the sound quality effect during speaker use due to loose installation.

[0035] Based on this, in order to ensure that the installation of the speaker is more convenient and reliable, and thus improve the assembly efficiency, a positioning hole is designed in the mounting part. It is located on the outer periphery of the mounting hole and between two adjacent connection holes. It can cooperate with the positioning plug on the speaker to improve the convenience of assembly.

[0036] Specifically, there are two positioning holes, which are arranged circumferentially at intervals around the outer periphery of the mounting hole. Connecting the two positioning holes yields line L1, and connecting the two connecting holes yields line L2. The included angle γ between L1 and L2 ranges from 40° to 50°. This arrangement, while satisfying speaker positioning and installation requirements, also enhances the stability of the mounting structure and provides better rigidity to the mounting component.

[0037] In one possible implementation, the mounting part is provided with a drainage groove for drainage, which is located below the mounting hole and connected to the mounting hole.

[0038] In this embodiment, a drainage groove is provided at the lower part of the mounting part, that is, at the lowest point below the mounting hole. When water flows, the water can be easily discharged through the drainage groove at the lowest point, avoiding water leakage caused by rainwater accumulation.

[0039] Specifically, the drainage channel can be a long strip structure extending in the vertical direction, or it can be different shapes such as round, rectangular, elliptical or polygonal, all of which can meet the drainage requirements of water flow and have good waterproof performance.

[0040] In one possible implementation, the inner door panel is provided with several reinforcing platforms located on the outer periphery of the mounting section. The reinforcing platforms protrude towards the central axis of the vehicle body, and the center of the reinforcing platform is provided with interior trim clip mounting holes for installing interior trim clips. In this embodiment, multiple interior trim clip mounting holes are provided around the mounting part. The interior trim clip mounting holes are arranged in a ring around the outer periphery of the mounting part. The distance between two adjacent interior trim clip mounting holes should not be too small to avoid positional interference between adjacent interior trim parts, and also to avoid affecting the embedding relationship between the mounting part and the inner door panel, thus ensuring the structural rigidity of the surrounding area of ​​the mounting part.

[0041] Based on the above structure, in order to avoid the impact of the interior trim clip mounting holes on the structural rigidity of the surrounding area of ​​the mounting part, an additional reinforcing platform is set at the location where the structural rigidity of the surrounding area of ​​the mounting part needs to be set. The reinforcing platform is used to compensate for the structural attenuation caused by the interior trim clip mounting holes, thus fully ensuring the structural rigidity of the outer periphery of the mounting part and meeting the installation requirements of the speaker.

[0042] In one possible implementation, the inner door panel has a stop mating surface located near its front edge and extending in the vertical direction, and the mounting part is arranged adjacent to the stop mating surface; a lower hinge mounting hole is provided at the lower front of the inner door panel, and the mounting hole is set higher than the lower hinge mounting hole.

[0043] In this embodiment, the stop-fit ​​surface provided on the inner panel of the door can be used as a reference surface for arranging the speaker. The speaker should be placed close to the stop-fit ​​surface to help the mounting part achieve good rigidity and improve the rationality of the structural layout. Based on the extension direction and specific dimensions of the stop-fit ​​surface, the mounting part's location and design parameters are selected to meet the rigidity requirements during speaker installation.

[0044] Based on this, the area with the lower hinge mounting hole at the lower front of the inner door panel should be avoided as much as possible from the speaker mounting area, that is, the mounting position should be avoided as much as possible. The two should be staggered in the vertical direction to avoid the force that would affect the mounting position after the hinge is installed in this position, thereby avoiding affecting the reliable installation of the speaker.

[0045] Compared with the prior art, the speaker mounting assembly provided in this application embodiment has a mounting part located in the lower front part of the inner door panel, which tends to gradually protrude outward from the inner door panel from bottom to top, forming a structure that is approximately embedded in the inner door panel. This facilitates the integrity of the mounting part and the inner door panel, helps to improve the dynamic and static stiffness of the mounting part, thereby meeting the overall stiffness requirements of the structure, ensuring reliable installation of the speaker, improving the sound quality of the speaker, and enhancing the passenger's driving experience.

[0046] The present invention also provides a vehicle including a speaker mounting assembly. The vehicle uses a mounting portion to mount a speaker, the mounting portion being located in the lower front part of the inner door panel, and having a tendency to gradually protrude outward from the inner door panel from bottom to top, forming a structure that is approximately embedded in the inner door panel. This facilitates ensuring the integrity of the mounting portion and the inner door panel, helps improve the dynamic and static stiffness of the mounting portion, thereby meeting the overall structural stiffness requirements, ensuring reliable speaker installation, improving speaker sound quality, and enhancing the passenger's driving experience.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

They 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, and therefore should not be construed as limiting the specific scope of protection of this invention.

[0052] Please refer to the following: Figures 1 to 6 The speaker mounting assembly and vehicle provided by the present invention will now be described. The speaker mounting assembly includes a door inner panel 1 and a mounting part 2 disposed on the door inner panel 1. The mounting part 2 is located at the lower front part of the door inner panel 1. The mounting part 2 is provided with mounting holes 21 for mounting a speaker. The mounting part 2 protrudes from the door inner panel 1 from top to bottom toward the central axis of the vehicle body.

[0053] Compared with the prior art, the speaker mounting assembly provided in this embodiment has a mounting part 2 located in the lower front part of the inner door panel 1, which tends to gradually protrude outward from the inner door panel 1 from bottom to top, forming a structure that is approximately embedded in the inner door panel 1. This facilitates the integrity of the mounting part 2 and the inner door panel 1, helps to improve the dynamic and static stiffness of the mounting part 2, thereby meeting the overall stiffness requirements of the structure, ensuring reliable installation of the speaker, improving the sound quality of the speaker, and enhancing the passenger's driving experience.

[0054] In this embodiment, the inner door panel 1 serves as the main carrier to provide mounting points for speakers and other accessories. The effective installation of speakers is achieved by setting mounting parts 2 on the inner door panel 1. The mounting parts 2 are located in the lower front area of ​​the inner door panel 1, which meets the positional installation requirements of the speakers and also meets the rigidity requirements of the mounting points.

[0055] The inner door panel 1 can be provided with concave and convex structures at different positions as needed. The mounting part 2 is integrally formed with the inner door panel 1. On the one hand, it helps to improve the structural rigidity of the speaker mounting position, meet the installation requirements of the speaker, and thus improve the sound quality during the use of the speaker. On the other hand, it also facilitates the processing and manufacturing of the structure, thereby reducing the production cost and assembly difficulty of the product.

[0056] Before installing other components, in order to ensure the structural strength of the inner door panel 1 itself, other reinforcing structures can be added to the inner door panel 1, such as reinforcing ribs, reinforcing strips or reinforcing bosses in local positions of the inner door panel 1, to ensure the strength and rigidity of the inner door panel 1, to achieve effective distribution of force channels, to facilitate the overall force on the disperser, to reduce structural deformation or even damage caused by excessive local force, and thus to ensure that the inner door panel 1 can cooperate with the outer door panel to form the entire door assembly.

[0057] Specifically, a curved surface structure that is recessed from top to bottom away from the central axis of the vehicle body can be provided on the inner door panel 1. The panel surface of the mounting part 2 extends in the vertical direction, so that the lower part of the mounting part 2 gradually protrudes from the inner door panel 1, and the upper part of the mounting part 2 is embedded relative to the inner door panel 1. The connection and transition between the two is natural and the overall integrity is strong.

[0058] As a parallel embodiment, the inner door panel 1 can also be configured as a panel extending in the vertical direction, with the mounting part 2 gradually protruding from the inner door panel 1 from top to bottom, which can also achieve the effect of the above-mentioned embedded design, satisfy the overall requirements of the mounting part 2 and the inner door panel 1, and thus facilitate the installation requirements of the speaker.

[0059] The structural design of the mounting part 2 and the inner door panel 1, without affecting the overall structure of the inner door panel 1, utilizes parametric and regularized structures to make the inner door panel 1 and the mounting part 2 form a complete unit. This facilitates the installation of the speaker through the mounting hole 21, allows forces to be transmitted in different directions through the structure, resulting in a more even distribution of force channels and a more regular structural design. This meets the static and dynamic stiffness requirements of the mounting point and helps to meet the assembly requirements of the speaker. This structure can serve as a universal design for multiple different vehicle models, bringing stability to the vehicle design.

[0060] Several issues need to be considered when installing loudspeakers. First, ensure the loudspeakers are securely installed to prevent resonance and noise caused by misalignment during use, thus ensuring optimal sound quality. Flexible pads or other components should be used to cushion and isolate the area where the loudspeaker contacts the mounting bracket. Furthermore, for loudspeakers requiring sealing, appropriate sealing materials should be used.

[0061] In addition, the speaker's own wiring should be considered. When connecting the wires, pay attention to the correspondence of positive and negative terminals to ensure correct and secure wiring. Wiring harness clips or other components can be used to limit and fix the wiring harness at different positions, preventing vibration and short circuits caused by collisions between the wiring and the inner door panel. Furthermore, the wiring connections should be properly wrapped with insulating tape to prevent poor contact or short circuits.

[0062] In addition, the speaker installation location should be waterproofed. The area on the inner door panel 1 where the speaker is located should be properly waterproofed. This can be achieved by installing drainage channels or waterproof membranes to prevent rainwater or water from entering during car washes, thus avoiding short circuits or speaker damage. After speaker installation, sound testing should be performed. A trial listening should be conducted to check if the speaker is working properly and if the sound quality meets expectations. If any abnormalities are found, the problem should be investigated promptly, examining both the installation structure and the speaker itself for possible causes, and then addressing them accordingly.

[0063] The speaker is mounted on the lower front part of the inner door panel 1, which is near the door stop. The mounting holes 21 of the mounting part 2 are used to form an embedded mounting for the speaker. The structure of the mounting part 2 being embedded into the inner door panel 1 further strengthens the structure and improves the reliability of the installation.

[0064] When the speaker is installed, it can form a more reliable connection structure with the inner door panel 1. When the two are connected, the force is more easily transmitted to different directions through the mounting part 2, making the force distribution more uniform. The above-mentioned structural design is relatively regular and applicable to different models. It can meet various needs such as installation and force, and is easy and quick to operate. The connection performance is reliable and can meet the assembly requirements of the speaker, making it easy to ensure the sound quality when the speaker is used and improve the comfort of passengers.

[0065] The speaker mounting structure adopts a standardized design, which allows for a shorter design cycle and ensures that the vehicle project is completed on schedule or ahead of schedule, thus guaranteeing a smooth market launch and a rapid capture of market share. At the same time, this standardized design also contributes to the stability of the vehicle design, resulting in a mature and stable design structure that ensures good durability and superior performance.

[0066] In some possible implementations, the aforementioned feature door inner panel 1 adopts, for example... Figure 1 , Figure 2 and Figure 5 The structure shown. See also Figure 1 , Figure 2 and Figure 5 The inner panel 1 of the door is provided with a recessed part 11 that gradually recesses from top to bottom toward the central axis side away from the vehicle body. The mounting part 2 is integrally formed on the recessed part 11, and the panel surface of the mounting part 2 extends in the vertical direction.

[0067] In this embodiment, the recessed portion 11 on the inner panel 1 of the car door can provide more space for the interior of the car and facilitate the design of the mounting portion 2. The mounting portion 2 can adopt a plate structure along the vertical direction, which can form an effect of gradually protruding from the surface of the recessed portion 11 from top to bottom, thereby making the upper part of the mounting portion 2 gradually embedded into the inner panel 1 of the car door.

[0068] Specifically, an acute angle is formed between the X-direction projection of the recessed portion 11 and the X-direction projection of the mounting portion 2. This angle is defined as δ, and the value of δ ranges from 5° to 10°. Specifically, different angle values ​​such as 5°, 6°, 7°, 8°, 9°, and 10° can be selected. The selection of the above angle values ​​can not only meet the requirements of the embedded design, but also avoid excessive space occupation caused by the mounting portion 2 protruding too much from the surface of the recessed portion 11. This ensures a reliable connection between the mounting portion 2 and the recessed portion 11, improves the integrity between the inner door panel 1 and the mounting portion 2, and has a significant effect on improving the overall rigidity of the mounting portion 2.

[0069] In some embodiments, the feature mounting portion 2 described above may adopt the following form: Figure 1 , Figure 2 and Figure 6 The structure shown. See also Figure 1 , Figure 2 and Figure 6 The outer periphery of the mounting part 2 is provided with a transition part 22 that connects with the recessed part 11. The transition part 22 and the mounting part 2 have an included angle α, where 40°≤α≤50°.

[0070] In this embodiment, a recessed portion 11 is provided on the inner door panel 1. The recessed portion 11 gradually extends downward and outward from the vehicle body, so that the mounting portion 2 is fitted into the inner door panel 1. A transition portion 22 is used to connect the mounting portion 2 and the recessed portion 11. As the transition portion 22 extends towards the recessed portion 11, it gradually tilts away from the central axis of the mounting hole 21, thereby making the transition between the mounting portion 2 and the recessed portion 11 more natural and the connection smoother, thus meeting the integrity requirements of the mounting portion 2 and the inner door panel 1.

[0071] The angle formed between the transition part 22 and the mounting part 2 is α, which is the angle between the extension line of the Y-direction section of the transition part 22 and the Y-direction section of the mounting part 2. α is 40° to 50°, and different angle values ​​such as 40°, 42°, 44°, 45°, 46°, 48°, and 50° can be selected. This helps to effectively distribute the force on the mounting part 2, ensure the effectiveness of the mounting part 2 in embedding relative to the inner door panel 1, and make the force in each direction relatively balanced. This prevents the situation where the stiffness is high in some places and weak in others, and avoids structural deformation of the mounting part 2, which would affect the reliable installation of the speaker. At the same time, the selection of the above angle also helps to simplify the processing technology and facilitates the integral stamping of the inner door panel 1 and the mounting part 2.

[0072] To facilitate speaker installation and allow the speaker to be easily inserted into the mounting hole 21, the mounting part 2 protrudes outward from the inner door panel 1. Furthermore, the mounting part 2 gradually protrudes outward from the inner door panel 1 from top to bottom, creating an embedded effect on the inner side of the inner door panel 1. This ensures effective connection between the mounting part 2 and the inner door panel 1, avoiding localized stress points caused by a cylindrical boss structure, and also helps improve the aesthetics of the vehicle's interior.

[0073] To achieve effective connection between the mounting part 2 and the inner door panel 1, the outer periphery of the mounting part 2 is connected to the inner door panel 1 via a transition part 22, that is, connected to the inner door panel 1 via an inclined extended peripheral wall. The transition part 22 adopts a 40° to 50° angle to meet the requirement that the entire speaker mounting structure can be embedded in the mounting hole 21. The transition part 22 can be set to a 45° angle to achieve a gradual connection between the transition part 22 and the inner door panel 1, which facilitates the overall sheet metal forming of the inner door panel 1 and the mounting part 2, improves the convenience of processing, and ensures that the force on the subsequent mounting part 2 can be effectively distributed to the inner door panel 1 through the transition part 22, avoiding excessive local stress that could cause high deformation and damage.

[0074] In some possible implementations, the aforementioned feature mounting part 2 adopts, for example... Figure 1 , Figure 2 and Figure 4 The structure shown. See also Figure 1 , Figure 2 and Figure 4 The mounting part 2 is provided with a reinforcing flange 23 connected to the circumferential edge of the mounting hole 21. The reinforcing flange 23 bends and extends outward from the vehicle body. The X-direction projection of the reinforcing flange 23 has an included angle β with the central axis of the mounting hole 21, where 3°≤β≤5°.

[0075] In this embodiment, the mounting hole 21 is used to allow the speaker to be embedded in the inner cavity of the door formed by the mounting part 2, the transition part 22 and the inner door panel 1, so as to avoid the problem of excessive space occupation caused by the speaker being completely exposed in the mounting part 2, and to help improve the overall aesthetics of the speaker mounting structure.

[0076] Specifically, the mounting hole 21 is a circular hole, consistent with the external structure of the speaker, which helps to achieve uniform force distribution. A reinforcing flange 23 is provided at the edge of the mounting hole 21. The reinforcing flange 23 extends away from the central axis of the vehicle body and gradually tilts towards the axis of the mounting hole 21, which can effectively improve the structural strength at the edge of the mounting hole 21 and avoid the strength reduction of the mounting part 2 caused by the opening of the mounting hole 21.

[0077] Based on this, the angle β formed between the X-direction projection of the flange 23 and the central axis of the mounting hole 21 is strengthened. β is selected from 3° to 5°, and different angle values ​​such as 3°, 3.5°, 4°, 4.5°, and 5° can be selected. This can effectively ensure the performance requirements of the speaker in the Y-direction during installation, improve the overall rigidity of the structure, avoid deformation and other problems, ensure the reliability of the installation, and thus help to ensure the sound quality of the speaker.

[0078] The reinforcing flange 23 extends in a complete circle along the circumferential edge of the mounting hole 21. The aforementioned included angle β is the draft angle of the reinforcing flange 23. The cross-section of the reinforcing flange 23 has an included angle of 3° to 5° with the central axis of the mounting hole 21, which not only facilitates forming and processing but also does not affect the operation of installing the speaker into the mounting hole 21. Therefore, by selecting the above draft angle, the support performance of the mounting part 2 in the Y direction is ensured, the overall rigidity of the mounting part 2 is improved, the reliability of the speaker installation is guaranteed, and the positional displacement of the speaker is avoided due to deformation of the mounting part 2 structure.

[0079] At the same time, the enhanced flange 23 can also guide the water flow on the outside of the inner door panel 1, preventing water from flowing into the inner door panel 1 on the side near the central axis of the vehicle body, thereby improving the waterproof performance around the speaker and ensuring the normal use of the speaker.

[0080] In some possible implementations, the aforementioned feature mounting part 2 adopts, for example... Figures 1 to 3 The structure shown. See also Figures 1 to 3 The mounting part 2 is connected to the speaker via a connector. The mounting part 2 is provided with a connecting hole 24 located on the outer periphery of the mounting hole 21 for mounting the connector. There are four connecting holes 24, which are distributed in a square.

[0081] In this embodiment, the speaker is connected to the mounting part 2 via a connector. The connector extends through holes at the corners of the speaker into the connecting hole 24, forming a reliable connection with the mounting part. Specifically, the connector can be a threaded connection or a riveted connection using bolts, screws, or anchors. To facilitate assembly, a weld nut can be pre-installed in the connecting hole 24, and the speaker is fixed to the mounting part 2 by the cooperation of the threaded connector and the weld nut.

[0082] Specifically, four connection holes 24 are provided on the outer periphery of the mounting hole 21. Adjacent connection holes 24 are arranged at a 90-degree angle, forming a square distribution. This allows for effective connection between the speaker and the connecting part at different circumferential positions, ensuring reliable speaker installation. For locations with connection holes 24, the edge of the mounting part 2 can be appropriately extended outwards to facilitate the arrangement of the connection holes 24 and ensure the reliability of subsequent speaker installation.

[0083] In the above structure, the mounting hole 21 is circular and the connecting hole 24 is arranged in a square shape. The combination of these two different shapes makes the structure more stable and regular. The parameters can be adjusted according to different vehicle models and different speaker sizes to ensure installation reliability.

[0084] In some embodiments, the feature mounting portion 2 described above may adopt the following form: Figures 1 to 6 The structure shown. See also Figures 1 to 6 The mounting part 2 is also provided with two positioning holes 25. Each positioning hole 25 is located between two adjacent connecting holes 24. The line connecting the two positioning holes 25 is defined as L1, and the line connecting the two adjacent connecting holes 24 is defined as L2. An included angle γ is formed between L1 and L2, where 40°≤γ≤50°.

[0085] In this embodiment, the angle and distance between adjacent mounting holes 21 are equal, which can ensure the reliable stability of the mounting part 2 under different forces in different circumferential positions, making the speaker installation stable and firm, and avoiding the sound quality effect during speaker use due to improper installation.

[0086] Based on this, in order to ensure that the installation of the speaker is more convenient and reliable, and thus improve the assembly efficiency, a positioning hole 25 is designed in the mounting part 2. It is located on the outer periphery of the mounting hole 21 and between two adjacent connecting holes 24. It can cooperate with the positioning plug on the speaker to improve the convenience of assembly.

[0087] Specifically, two positioning holes 25 are provided, and the positioning holes 25 and the connecting holes 24 are arranged circumferentially at intervals around the outer periphery of the mounting hole 21. A line L1 is formed by connecting the two positioning holes 25, and a line L2 is formed by connecting the two connecting holes 24. The included angle γ between L1 and L2 ranges from 40° to 50°. This arrangement, while satisfying the positioning and installation of the speaker, can also improve the stability of the mounting structure and give the mounting part 2 better rigidity performance.

[0088] There are four connecting holes 24 arranged in a square structure, with adjacent connecting holes 24 spaced at a 90° angle. These four connecting parts can be used to connect and fix different points on the speaker. The positioning holes 25 on the mounting part 2 should not overlap with or be too close to the connecting holes 24 to avoid mutual interference during the installation of positioning or connecting parts, thus improving operational convenience.

[0089] The line connecting the two positioning holes 25 is set at a 45° angle with the line connecting the two adjacent mounting holes 21, which effectively increases the distance between the positioning parts and the connecting parts, making it convenient to perform positioning operations before connection. While ensuring positioning accuracy, it can also effectively improve the stability of the structural connection and ensure reliable installation of the speaker.

[0090] In some possible implementations, the aforementioned feature mounting part 2 adopts, for example... Figures 1 to 3 The structure shown. See also Figures 1 to 3 The mounting part 2 is provided with a drainage groove 26 for drainage. The drainage groove 26 is located below the mounting hole 21 and is connected to the mounting hole 21.

[0091] In this embodiment, a drainage groove 26 is provided at the lower part of the mounting part 2, that is, at the lowest point below the mounting hole 21. When there is water flow, the water can be easily discharged through the drainage groove 26 located at the lowest point, avoiding water leakage caused by rainwater accumulation.

[0092] Specifically, the drainage channel 26 can be a long strip structure extending in the vertical direction, or it can be a different shape such as round, rectangular, elliptical or polygonal, all of which can meet the drainage requirements of water flow and provide good waterproof performance.

[0093] In some possible implementations, the aforementioned feature door inner panel 1 adopts, for example... Figures 1 to 3 The structure shown. See also Figures 1 to 3 The inner panel 1 of the door is provided with several reinforcing platforms 28 located on the outer periphery of the mounting part 2. The reinforcing platforms 28 are protruding towards the central axis side of the vehicle body. The center of the reinforcing platform 28 is provided with interior trim clip mounting holes 27 for installing interior trim clips.

[0094] In this embodiment, a plurality of interior trim clip mounting holes 27 are provided around the mounting part 2. The interior trim clip mounting holes 27 are arranged in a ring around the outer periphery of the mounting part 2. The gap between two adjacent interior trim clip mounting holes 27 should not be too small to avoid positional interference between adjacent interior trim parts, and also to avoid affecting the embedding relationship between the mounting part 2 and the inner door panel 1, thus ensuring the structural rigidity of the periphery of the mounting part 2.

[0095] Based on the above structure, in order to avoid the impact of the interior trim clip mounting holes 27 on the structural rigidity of the surrounding area of ​​the mounting part 2, an additional reinforcing platform 28 is provided at the location where the structural rigidity of the surrounding area of ​​the mounting part 2 needs to be set. The reinforcing platform 28 is used to compensate for the structural attenuation caused by the interior trim clip mounting holes 27, thus fully ensuring the structural rigidity of the outer periphery of the mounting part 2 and meeting the installation requirements of the speaker.

[0096] In some possible implementations, the aforementioned feature door inner panel 1 adopts, for example... Figure 1 and Figure 3 The structure shown. See also Figure 1 and Figure 3 The inner door panel 1 is provided with a stop mating surface 12 that is located near its front edge and extends in the vertical direction. The mounting part 2 is arranged adjacent to the stop mating surface 12. The lower front of the inner door panel 1 is provided with a lower hinge mounting hole 13, and the mounting hole 21 is set higher than the lower hinge mounting hole 13.

[0097] In this embodiment, the stop-fit ​​surface 12 provided on the inner panel 1 of the door can be used as a reference surface for arranging the speaker. The speaker should be placed close to the mating surface. This mating surface helps the mounting part 2 to form good rigidity performance and improves the rationality of the structural layout. According to the extension direction and specific dimensions of the stop-fit ​​surface 12, the setting position and design parameters of the mounting part 2 are selected accordingly to meet the rigidity requirements during speaker installation.

[0098] Based on this, the area where the lower hinge mounting hole 13 is located at the lower front of the inner door panel 1 should be avoided as much as possible from the speaker mounting area, that is, the mounting part 2 should be avoided as much as possible. The two should be staggered in the vertical direction to avoid the force that would affect the mounting part 2 after the hinge is installed in this position, thereby avoiding affecting the reliable installation of the speaker.

[0099] The mounting part 2 of the aforementioned speaker mounting assembly is located in the lower front part of the inner door panel 1. It tends to protrude outward from the inner door panel 1 from bottom to top, forming a structure that is approximately embedded in the inner door panel 1. This facilitates the integrity of the mounting part 2 and the inner door panel 1, helps to improve the dynamic and static rigidity of the mounting part 2, thereby meeting the overall rigidity requirements of the structure, ensuring reliable installation of the speaker, improving the sound quality of the speaker, and enhancing the passenger's driving experience.

[0100] Based on the same inventive concept, this application also provides a vehicle, which includes a speaker mounting assembly. The vehicle uses a mounting part 2 to mount a speaker. The mounting part 2 is located in the lower front part of the inner door panel 1 and tends to gradually protrude outwards from the inner door panel 1 from bottom to top, forming a structure that is approximately embedded in the inner door panel 1. This facilitates ensuring the integrity of the mounting part 2 and the inner door panel 1, helps improve the dynamic and static stiffness of the mounting part 2, thereby meeting the overall structural stiffness requirements, ensuring reliable speaker installation, improving speaker sound quality, and enhancing the passenger's driving experience.

[0101] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
