At present, most of the power amplifier brackets in the industry only have mounting holes for power amplifier modules and fixing holes for matching vehicle bodies. The power amplifier bracket is generally matched with the power amplifier as a 01-level part, and then matched with the vehicle as an assembly. However, the shapes of power amplifiers with different configurations are different. Therefore, the power amplifier bracket needs to be adjusted according to the power amplifier module, and then matched with the vehicle body structure, which may cause the diversification of the power amplifier bracket and waste development costs.

[0006] According to the mounting bracket of the present application, the plurality of mounting areas arranged at intervals provide a plurality of mounting positions, which facilitates the selection according to the actual type of power amplifier, thereby adapting to power amplifiers of different specifications. The plurality of mounting part groups 200 can install power amplifiers of multiple different specifications, thereby improving the adaptability of the mounting bracket to power amplifiers of different types.

[0014] The bracket body is provided with a first protruding part, and the first protruding part is used for fixing to the vehicle body, and along the thickness direction of the bracket body, the first protruding part protrudes from the first side surface.

[0015] In the above scheme, the first protruding part is used for fixing to the vehicle body, so that the mounting bracket is more closely attached to the vehicle body panel surface, helping to reduce shock and abnormal noise, reduce the influence of external vibration on the power amplifier, thereby improving the sound quality to a certain extent, and at the same time, a gap is formed between the first protruding part and the first side surface, which can provide heat dissipation space for the power amplifier, helping to ensure the performance of the power amplifier, prolong the service life of the power amplifier and improve the system stability of the power amplifier; in addition, the power amplifier is arranged on the second side surface, and since a gap is formed between the first protruding part and the first side surface, the power amplifier can be spaced apart from the area of the vehicle body where the mounting bracket is arranged, thereby reducing the influence of vehicle vibration on the power amplifier.

[0038] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0039] Unless otherwise defined, all the technical and scientific terms used in the present application have the same meanings as those commonly understood by those skilled in the art to which the present application belongs; the terms used in the specification of the present application are only for the purpose of describing the specific embodiments of the present application, and are not intended to limit the present application; the terms "include" and "have" and any variations thereof in the specification and claims of the present application and the above description of drawings are intended to cover the non-exclusive inclusion. The terms "first", "second" and the like in the specification and claims of the present application or the above description of drawings are used to distinguish different objects, and are not intended to describe a specific order or primary and secondary relationship.

[0040] Reference to an "example" in this application means that a particular feature, structure, or characteristic described in connection with the example can be included in at least one example of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same example, nor are they necessarily mutually exclusive or alternative examples to one another. It is expressly understood that the examples described in this application can be combined with each other in their various permutations.

[0041] In the description of the application, it is necessary to point out that, unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting", "attaching" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0042] The term "and / or" in this application is only a description of the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B can mean that A exists alone, A and B exist together, and B exists alone. In addition, the character " / " in this application generally represents that the front and rear associated objects have an "or" relationship.

[0043] "Multiple" appearing in this application means more than two (including two), and similarly, "multiple groups" means more than two groups (including two groups), and "multiple pieces" means more than two pieces (including two pieces).

[0044] As an important part of the sound system, the stability and safety of the power amplifier are crucial to the normal operation of the entire system. Proper installation of the support design helps to improve the heat dissipation performance of the power amplifier and ensure its stable operation at an appropriate temperature. The stability and shock absorption effect of the power amplifier mounting bracket also have a certain influence on the sound quality. Stable installation can reduce the interference of external vibration on the power amplifier, thereby improving the sound quality performance to a certain extent.

[0045] At present, most of the power amplifier brackets in the industry only have the mounting hole of the power amplifier module and the fixing hole matching the vehicle body mechanism. The power amplifier bracket is generally matched with the power amplifier as a 01 level part, and then matched with the whole vehicle as an assembly part. The shapes of power amplifiers from different suppliers and with different configurations are different. The power amplifier bracket generally follows the change of the power amplifier module and is adjusted to match the vehicle body structure, which will cause the diversification of the power amplifier bracket and waste the development cost.

[0046] In addition, the color of the power amplifier is generally quite different from the interior trim of the whole vehicle. Considering the heat dissipation characteristics of the power amplifier, the power amplifier cannot be directly covered with a carpet, and a power amplifier decorative cover that matches the interior trim of the whole vehicle and meets the heat dissipation conditions of the power amplifier is matched above the power amplifier. At present, most of the decorative covers need to provide fixing structures on the vehicle body or other positions, which will also affect the platformization of the whole vehicle parts and cause cost waste.

[0047] Therefore, in order to improve the adaptability of the mounting bracket, the mounting bracket for mounting the power amplifier of the vehicle can adapt to power amplifiers of different specifications, please refer to Figure 1 , which comprises a bracket body 100 and a plurality of mounting groups 200. It can be understood that the plurality of mounting groups 200 can fix the power amplifier, and the plurality of mounting groups 200 can provide a plurality of mounting sites for the bracket body 100, which helps the bracket body 100 to adapt to power amplifiers of different specifications.

[0048] Along the circumference of the bracket body 100, the bracket body 100 has a plurality of spaced mounting areas 110; it can be understood that the plurality of spaced mounting areas 110 provides a plurality of mounting positions, which expands the selection range of the mounting positions when mounting power amplifiers of different specifications, thereby facilitating the adaptation to more specifications of power amplifiers, while ensuring the stress dispersion effect of the bracket body 100 at each mounting area 110, reducing the probability of stress concentration of each mounting area 110.

[0049] Each mounting group 200 comprises a plurality of mounting portions, it can be understood that the plurality of mounting portions can fix the power amplifier, and the plurality of mounting portions can further provide more mounting sites for the bracket body 100, which helps to adapt to power amplifiers of different specifications.

[0050] As an example, the fixing mode of the mounting portion and the power amplifier can be buckle fixing, bolt fixing or adhesive fixing, which is not limited by the present application, and the mounting portion can be integrally formed with the bracket body 100, bolted or clamped, which is not limited by the present application.

[0051] The plurality of mounting portions in each mounting group 200 correspond to the plurality of mounting areas 110 one by one, the mounting portions in each mounting group 200 are arranged in the corresponding mounting areas 110, and the plurality of mounting portions in each mounting group 200 are used to fix the corresponding type of power amplifier.

[0052] In the above scheme, the plurality of mounting portion groups 200 can mount power amplifiers of multiple different specifications, thereby improving the adaptability of the mounting support to different types of power amplifiers, and multiple different specifications or types of power amplifiers can use the same set of mounting supports, thereby reducing design and production costs.

[0053] In other embodiments, the plurality of mounting portion groups 200 includes a first mounting portion group 210 and a second mounting portion group 220, and it can be understood that the first mounting portion group 210 and the second mounting portion group 220 can respectively serve to mount power amplifiers, and the first mounting portion group 210 and the second mounting portion group 220 can be respectively used to mount different types of power amplifiers, thereby improving the applicability of the mounting support.

[0054] The plurality of mounting portions in the first mounting portion group 210 are configured as a plurality of first mounting portions 211, the plurality of mounting portions in the second mounting portion group 220 are configured as a plurality of first mounting portions 211, and each mounting area 110 is provided with a corresponding first mounting portion 211 and a corresponding first mounting portion 211.

[0056] In other embodiments, the first mounting portion 211 is configured as a first mounting hole 211a, and it can be understood that the power amplifier can be fixed to the mounting support through the first mounting hole 211a, and the first mounting hole 211a can penetrate the mounting support along the thickness direction of the mounting support, thereby improving the firmness between the power amplifier and the mounting support.

[0057] The first mounting portion 211 is configured as a second mounting hole 221a, and it can be understood that the power amplifier can be fixed to the mounting support through the second mounting hole 221a, and the second mounting hole 221a can penetrate the mounting support along the thickness direction of the mounting support, thereby improving the firmness between the power amplifier and the mounting support.

[0058] The first mounting hole 211a and the second mounting hole 221a of each mounting area 110 are arranged in a spaced manner, and it can be understood that the first mounting hole 211a and the second mounting hole 221a are arranged in a spaced manner, improving the compactness of the layout of the mounting area 110, facilitating the arrangement of more mounting points on the mounting support, thereby helping to improve the adaptability to different types of power amplifiers.

[0059] In addition, the first mounting hole 211a and the second mounting hole 221a arranged at intervals can more effectively disperse the pressure of the power amplifier on the mounting bracket, and improve the stability and reliability of the mounting bracket when fixing different types of power amplifiers.

[0060] In the above scheme, the first mounting hole 211a and the second mounting hole 221a arranged at intervals are arranged in each mounting area 110, so that each mounting area 110 can provide a mounting site for power amplifiers of different specifications, thereby helping to improve the applicability of the mounting bracket.

[0061] In other embodiments, the bracket body 100 is configured as a polygonal plate 101, and the corner regions of the polygonal plate 101 are configured as the mounting areas 110.

[0062] It can be understood that the corner regions of the polygonal plate 101 as the mounting areas 110 have a certain interval between the mounting areas 110, thereby surrounding a larger area for accommodating the power amplifier, facilitating the adaptation to power amplifiers of different sizes. At the same time, the corner regions as the mounting areas 110 can provide more arrangement space for the plurality of mounting portions in the mounting areas 110, thereby helping to improve the adaptability of the mounting bracket.

[0063] In addition, the corner regions of the polygonal plate 101 as the mounting areas 110 can more effectively disperse the pressure to the entire bracket structure, reduce the probability of stress concentration of the mounting areas 110, and thereby improve the overall stability of the bracket.

[0064] In other embodiments, please refer to Figure 2 , along the thickness direction of the bracket body 100, the bracket body 100 has a first side surface 120 and a second side surface 130 arranged oppositely. It can be understood that the second side surface 130 can serve as a support for the power amplifier, thereby helping to improve the stability of the power amplifier.

[0065] The bracket body 100 is provided with a first protruding portion 140, and the first protruding portion 140 is used for fixing to the vehicle body. Along the thickness direction of the bracket body 100, the first protruding portion 140 protrudes from the first side surface 120.

[0066] It can be understood that the first protruding portion 140 is used for fixing to the vehicle body, so that the bracket is more closely attached to the vehicle body panel, thereby helping to reduce vibration and abnormal sound, reduce the influence of external vibration on the power amplifier, and thereby improve the sound quality to a certain extent.

[0067] Meanwhile, a gap is formed between the first protruding part 140 and the first side surface 120, which can provide a heat dissipation space for the power amplifier, help ensure the performance of the power amplifier, prolong the service life of the power amplifier, and improve the system stability of the power amplifier. In addition, the power amplifier is arranged on the second side surface 130. Since the gap is formed between the first protruding part 140 and the first side surface 120, the power amplifier can be spaced apart from the area on the vehicle body where the mounting bracket is arranged, thereby reducing the influence of vehicle vibration on the power amplifier.

[0068] In some other embodiments, the polygonal plate 101 has a plurality of edge regions 101a, which refers to a region with a predetermined width extending inward from the outer edge of the polygonal plate 101. For example, the edge region refers to a region with a width of 30-50 mm extending inward from the corresponding edge.

[0069] At least part of the plurality of edge regions 101a is provided with the first protruding part 140.

[0070] It can be understood that the plurality of first protruding parts 140 further increases the contact area between the mounting bracket and the vehicle body, thereby improving the firmness and stability of the connection between the mounting bracket and the vehicle body, so that the mounting bracket can more evenly bear the force from the vehicle body or other components, reducing the risk of loosening or damage caused by vibration or external force.

[0071] Optionally, the bracket body 100 is provided with a second protruding part 150 for fixing the decorative plate. The second protruding part 150 protrudes from the second side surface 130 in the thickness direction of the bracket body 100.

[0073] In addition, the second protruding part 150 can serve as a positioning point to help the installer quickly and accurately find the installation position of the decorative plate, reducing the probability of power amplifier decoration cover repair due to installation direction error.

[0074] In some other embodiments, each mounting region 110 is provided with a second protruding part 150.

[0075] It can be understood that the mounting bracket can be connected to the decorative plate through the plurality of mounting regions 110, which can more effectively disperse the stress borne by the mounting bracket, avoid deformation or damage caused by excessive local stress, help improve the overall structural strength of the bracket, and help improve the installation strength for different types of power amplifiers.

[0076] Meanwhile, since the installation areas 110 are arranged at intervals, the plurality of second protruding portions 150 are arranged at intervals, so as to provide more installation space for different types of decorative plates, so as to facilitate installation of corresponding decorative plates when power amplifiers of different specifications are installed.

[0077] Optionally, the bracket body 100 is provided with a lightening hole 300, which penetrates the bracket body 100 along the thickness direction of the bracket body 100.
