[0002] An amplifier is a power amplifier used to amplify various sound signals played from an audio source to drive speakers to produce sound. With consumers' increasing pursuit of higher quality car audio systems, the demand for car amplifiers is growing year by year. Existing car amplifiers consist of a radiator cover, a printed circuit board, and a lower cover. The radiator cover includes three or four horizontally extending mounting angles. These angles, combined with the connection structure on the vehicle body, allow for a fixed installation of the amplifier. However, this type of amplifier is only suitable for installation on large flat surfaces. For locations such as side pillars or corners of the vehicle body, the complex shape of the connection structure and the fact that the mounting surfaces on the connection structure are not on the same plane prevent the existing mounting angles from fully fitting into the connection structure, leading to unreliable connections or even installation failure.

[0007] In this embodiment of the utility model, the first foot, the second foot, and the third foot are respectively disposed on the three sides of the second cover, and the remaining side of the second cover is provided with an interface for the power amplifier device.

The main board can be assembled with the first cover to form an installation space. The connecting side plate protrudes outward to form a first leg and a second leg.

[0010] In this embodiment of the utility model, the splicing motherboard is designed to protrude outward on the connecting side plate to form a clearance space, which is used to accommodate the electronic components of the power amplifier device.

The first cover and the second cover are joined together to form an installation space for accommodating the amplifier device. The second cover protrudes outward to form a first leg and a second leg that are spaced apart. According to the arrangement requirements of the vehicle-mounted amplifier device, connection structures are provided on the underside of the seat, the rear side panel, the rear floor, and other locations of the vehicle body. Due to the limited space in the vehicle body and the need to meet the installation requirements of other vehicle-mounted devices, these connection structures do not have a large flat surface for the vehicle-mounted amplifier device to be laid flat. Instead, different installation surfaces are formed at different locations. The first leg and the second leg are correspondingly formed with first and second connecting surfaces that fit and connect with different locations of the connection structure to achieve the stability of the vehicle-mounted amplifier device installed on the vehicle body. Compared with the existing vehicle-mounted amplifier structure, it is more suitable for installation on complex connection structures.

[0036] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0037] The following description of the vehicle-mounted power amplifier device and automobile of this utility model is based on the accompanying drawings.

[0038] like Figures 1 to 3 As shown, this utility model provides a vehicle-mounted power amplifier device, wherein the vehicle-mounted power amplifier device includes:

[0039] First cover 1;

[0040] The second cover 2 is assembled with the first cover 1 to form an installation space for accommodating the power amplifier device. The second cover 2 protrudes outward to form a first leg 21 and a second leg 22 that are spaced apart. The first leg 21 and the second leg 22 are respectively formed with a first connecting surface 211 and a second connecting surface 221 that are attached to different positions of the connecting structure. The first connecting surface 211 and the second connecting surface 221 are located on different planes.

[0041] The vehicle-mounted amplifier unit includes a first cover 1 and a second cover 2. The first cover 1 and the second cover 2 are joined together to form an installation space for accommodating the amplifier device. The second cover 2 protrudes outward to form a first support 21 and a second support 22 spaced apart. Depending on the arrangement requirements of the vehicle-mounted amplifier unit, connecting structures are provided under the seats, on the rear side panels, and on the rear floor of the vehicle body. Due to limited vehicle space and the need to accommodate the installation of other vehicle-mounted devices, these connecting structures do not have a large flat surface for the vehicle-mounted amplifier unit to lie flat. Instead, different installation surfaces are formed at different locations. The first support 21 and the second support 22 correspondingly form a first connecting surface 211 and a second connecting surface 221 that fit and connect with different locations on the connecting structures, thus ensuring the stability of the vehicle-mounted amplifier unit on the vehicle body. Compared to existing vehicle-mounted amplifier structures, this design is more suitable for installation on complex connecting structures. Furthermore, the second cover 2 integrates the functions of the vehicle-mounted amplifier's cover plate and bracket, eliminating the need for a separate bracket, reducing the number of parts, and lowering the overall cost.

[0042] like Figure 3 As shown in the embodiment of this utility model, the raised height of the first leg 21 is greater than the raised height of the second leg 22, and the first connecting surface 211 and the second connecting surface 221 are inclined to each other so that the first connecting surface 211 and the second connecting surface 221 are respectively assembled with different mounting surfaces of the mounting structure.

[0043] Specifically, the first connecting surface 211 can be fitted and connected to the horizontal mounting surface of the connecting structure, and the second connecting surface 221 is set at an angle to the first connecting surface 211 so that the second connecting surface 221 can be fitted and connected to the first angled mounting surface of the connecting structure. On the one hand, the first support 21 and the second support 22 at different heights can be aligned with planes at different heights on the connecting structure respectively; on the other hand, when installing the vehicle amplifier device, the first support 21 can be used as a positioning reference to first fit and connect with the horizontal mounting surface of the connecting structure, and then the vehicle amplifier device can be finely adjusted so that the second connecting surface 221 fits and connects with the first angled mounting surface of the connecting structure. The first connecting surface 211 is set horizontally, which makes it easy for the operator to align and fit it with the horizontal mounting surface of the connecting structure, thereby improving installation efficiency. It should be noted that the above-mentioned horizontal mounting surface and angled mounting surface only indicate the relative position of the two mounting surfaces on the connecting structure, and do not limit the specific angle of the mounting surfaces. Of course, this utility model is not limited to this. The first leg 21 and the second leg 22 can also be set at the same height, and the first connecting surface 211 and the second connecting surface 221 can be inclined to each other; or the first leg 21 is higher than the second leg 22, and the first connecting surface 211 and the second connecting surface 221 are parallel to each other.

[0044] like Figure 1 and Figure 2 As shown in the embodiment of this utility model, the second cover 2 also protrudes outward to form a third support leg 23. The third support leg 23 forms a third connecting surface 231. The third connecting surface 231 is set to be inclined to the first connecting surface 211 and / or the second connecting surface 221, so that the third connecting surface 231 is in close contact with the other mounting surfaces of the connecting structure.

[0045] Specifically, the first support leg 21, the second support leg 22, and the third support leg 23 are correspondingly located on the three sides of the second cover 2, while the remaining side of the second cover 2 has an interface for the power amplifier device. The three supports are arranged in a triangle, defining a plane through three connection points, thus improving the stability of the vehicle-mounted power amplifier installation. Of course, to ensure the stability of the vehicle-mounted power amplifier device, the number of supports can be increased based on the specific shape of the connection structure. Specifically, the specific height of each support leg and the tilt angle of each connection surface are designed according to the specific shape of the connection structure. Figure 3 In one specific embodiment, the first leg 21 and the second leg 22 are respectively disposed on the left and right sides of the second cover 2. The first connecting surface 211 of the first leg 21 is horizontally arranged, and the second leg 22 and the third leg 23 are at the same height. The second connecting surface 221 is inclined to the left, and the third connecting surface 231 is inclined to the right. In other specific embodiments, the raised height of the first leg 21 can be the second highest, the lowest, or the same for all three legs. The second connecting surface 221 and the third connecting surface 231 can be horizontal or inclined.

[0046] In this embodiment of the invention, the first leg 21, the second leg 22, and the third leg 23 all have a first connecting hole 201 formed through them, and the central axis of the first connecting hole 201 is perpendicular to the connecting surface of the corresponding leg. The first connecting hole 201 is used for fasteners to pass through. Specifically, the fastener is a bolt or screw, and a threaded hole is correspondingly provided on the connecting structure of the vehicle body. The vehicle amplifier bracket is fixed by a threaded connection, which facilitates disassembly and maintenance. Furthermore, when the first connecting hole 201 is formed, it is ensured that the central axis of the first connecting hole 201 is perpendicular to the connecting surface of the corresponding leg, thereby pressing the leg vertically to the connecting structure of the vehicle body and avoiding axial shearing force on the fastener.

[0047] Of course, this utility model is not limited to this. The above-mentioned support legs can also be spliced ​​with the connecting structure by adhesive, in which case the opening of the first connecting hole 201 can be eliminated.

[0048] In this embodiment of the invention, the second cover 2 includes a main board 24 and a connecting side plate 25 surrounding the main board. The main board 24 can be assembled with the first cover 1 to form an installation space. The connecting side plate 25 protrudes outward to form a first leg 21 and a second leg 22. By setting the connecting side plate 25 extending outward from the main board 24, the first leg 21 and the second leg 22 are both located on the outer circumferential side of the first cover 1. The first cover 1 will not block the first connecting hole 201 on the leg, which facilitates the overall assembly and disassembly of the vehicle amplifier device by the operator. Specifically, the third leg 23 also adopts the same arrangement as the above-mentioned legs, which will not be described in detail here.

[0049] In this embodiment of the invention, the main board 24 is designed to protrude outward on the connecting side plate 25 to form a clearance space 241, which is used to accommodate the electronic components of the power amplifier device. The power amplifier device is a combination of a circuit board and various electronic components. Considering the limited mounting area of ​​the circuit board itself, electronic components are provided on both the upper and lower sides of the circuit board. The electronic components on the upper side are placed inside the first cover 1, while the electronic components on the lower side are placed inside the clearance space 241 of the second cover 2 to avoid interference between the electronic components and the second cover 2.

[0050] In this embodiment of the invention, a connecting portion 242 is formed inwardly protruding on the inner wall of the main board 24. The top end of the connecting portion 242 is used to abut against the power amplifier device, and a second connecting hole 202 for fasteners to pass through is provided at the top end of the connecting portion 242. During the driving process of the car, the vibration of the vehicle body will also be transmitted to the vehicle power amplifier device. In order to minimize the vibration of the power amplifier device relative to the first cover 1 and the second cover 2, fasteners need to be inserted at different positions of the power amplifier device, including the edge position and the center position of the power amplifier device. Due to the setting of the clearance space 241, the power amplifier device and the main board 24 do not directly contact each other. If the pre-tightening force of the fastener is too large, it is easy to cause deformation of the circuit board of the power amplifier device or the main board 24. The setting of the connecting portion 242 realizes the contact between the main board 24 and the circuit board at the connection position, which can avoid interference between the electronic components and the second cover 2 while avoiding deformation. Of course, the specific location of the connector 242 needs to be determined based on the location of the electronic components on the circuit board to avoid interference between the connector 242 and the electronic components.

[0051] Specifically, three connecting parts 242 are formed on the assembled motherboard 24, and the three connecting parts 242 are arranged in a triangle.

[0052] In this embodiment of the invention, a reinforcing rib 243 is also protruding on the inner wall of the assembled main board 24 to improve the structural strength of the assembled main board 24. Specifically, the reinforcing rib 243 includes three reinforcing rib segments arranged in an I-shape. Further, three connecting portions 242 are located between two parallel reinforcing rib segments, and the middle reinforcing rib segment has one connecting portion 242 on one side and two connecting portions 242 on the other side.

[0053] In this embodiment of the invention, a positioning post 13 is provided on the side of the first cover 1 facing the second cover 2, and a positioning hole 205 corresponding to the positioning post 13 is formed on the second cover 2. During the assembly of the vehicle-mounted amplifier device, the operator places the second cover 2 on top of the first cover 1, allowing the positioning post 13 to pass through the positioning hole 205, thereby quickly aligning the holes on the first cover 1 and the second cover 2 and improving assembly efficiency. Furthermore, the number of positioning posts 13 and positioning holes 205 is set to two. The two positioning posts 13 can limit the position of the second cover 2, ensuring that the position of the second cover 2 does not shift during the tightening of screws. Even further, through holes corresponding to the positioning posts 13 are also formed on the circuit board of the amplifier device.

[0054] like Figure 1 and 4As shown, in this embodiment of the present invention, the first cover 1 includes a top cover portion 11 and a side plate portion 12 surrounding the top cover portion 11. The top cover portion 11, facing away from the second cover 2, also has multiple parallel heat sinks 111 for quickly dissipating heat from the power amplifier device. The top cover portion 11, facing the second cover 2, has multiple grooves corresponding to the shape of the electronic components of the power amplifier device, allowing the electronic components to extend into the grooves and directly contact the top cover portion 11, thereby further improving heat dissipation efficiency. The side plate portion 12 is used to connect with the second cover 2. See [reference needed]. Figure 2 and Figure 4 The second cover 2 has a third connecting hole 203 and a fourth connecting hole 204. The third connecting hole 203 is provided corresponding to the top cover 11. Fasteners pass through the third connecting hole 203 and connect the second cover 2, the circuit board and the top cover 11 in sequence to ensure the connection strength of the first cover 1, the power amplifier device and the second cover 2. The fourth connecting hole 204 is provided corresponding to the side plate 12. Fasteners pass through the fourth connecting hole 204 and connect the second cover 2 and the side plate 12 in sequence, so that the first cover 1 and the second cover 2 are directly connected to further reduce the relative vibration between the two and ensure the stable output of the vehicle power amplifier device during vehicle vibration.

[0055] In this embodiment of the invention, the second cover 2 is integrally stamped to reduce the processing steps. Specifically, the three legs are all located on the outermost side of the connecting side plate 25, and the three legs are stamped into an open shape on the side away from the main board 24 to reduce material usage and lower production costs. Of course, in other embodiments of the invention, the three legs of the second cover 2 can also be set as independent components and then assembled with the connecting side plate 25 by welding or bolting.
