Description

Technical Field

[0001] This utility model relates to the field of automotive electronic equipment installation structure technology, and in particular to a height-adjustable vehicle power amplifier. Background Technology

[0002] Car amplifiers are one of the core components of a car audio system. Their function is to amplify audio signals and drive speakers to reproduce high-quality sound. With the development of automotive electronics technology and the increasing demands of consumers for sound quality, car amplifiers have gradually evolved from integrated designs to independent and professional designs, incorporating technologies such as digital signal processing and multi-channel output to meet users' needs for personalized sound effects and immersive listening experiences.

[0003] Currently, most car amplifiers on the market use a fixed installation method, with common installation locations including under the driver or passenger seat and in the spare tire storage area of ​​the trunk. This type of design uses metal brackets or plastic clips to directly fix the device to the vehicle body structure, resulting in a tight fit between the device and the bottom of the car or trunk floor. While some high-end models use vibration-damping materials in the amplifier housing, their installation method is still primarily rigid, and the installation location is limited by the available space inside the vehicle, lacking flexibility.

[0004] The existing installation methods for car amplifiers have significant defects. Rigid fixing causes the device to directly transmit vibrations to the car body. Long-term use can easily affect the stability of internal electronic components due to resonance. The device is tightly attached to the car body floor or trunk floor without leaving buffer gaps or heat dissipation space, making it difficult to effectively dissipate the heat generated during operation, accelerating component aging and reducing the life of the device. The height is not adjustable after installation, which cannot meet the personalized needs of different car models or users for amplifier placement. Utility Model Content

[0005] To overcome the drawbacks of rigid fixation and limited heat dissipation, this invention provides a height-adjustable vehicle power amplifier, aiming to solve the aforementioned shortcomings.

[0006] A height-adjustable car amplifier includes a car amplifier, a mounting bracket, and a connecting bracket. The mounting bracket is fixed inside the vehicle. A guide rod is fixedly connected to one side of the mounting bracket, and a lead screw is rotatably connected to the other side. The connecting bracket is slidably connected inside the mounting bracket. One connecting bracket is slidably connected to the guide rod, and the other is threadedly connected to the lead screw. The car amplifier is mounted on two connecting brackets. A fixed seat is connected to the top of the mounting bracket. An adjusting column is rotatably connected to the top of the fixed seat. The adjusting column is located at the top of the lead screw, and a locking plate is connected to the top of the adjusting column. The locking plate has two limiting holes. A conversion component for controlling the rotation direction of the lead screw is provided inside the fixed seat.

[0007] Furthermore, the conversion assembly includes a conversion ring frame, a bolt guide block, a wedge frame, and a first return spring. The conversion ring frame is slidably connected to the adjusting column. A block passing through the adjusting column is provided at the top of the conversion ring frame. The bolt passes through the block and is slidably connected to the limiting hole. The bolt is interference-fitted with the locking plate. Several mating parts are connected around the inner side of the conversion ring frame. A bidirectional misaligned ratchet is connected to the top of the lead screw. A limiting ring is connected to the middle of the bidirectional misaligned ratchet. Both guide blocks are provided with extension plates that are slidably connected to the limiting ring. The guide blocks are vertically slidably connected to the mating parts. A wedge frame is slidably connected to the side of the guide block facing the bidirectional misaligned ratchet. The side of the guide block away from the bidirectional misaligned ratchet is slidably connected to the conversion ring frame. The wedge frame engages with the ratchet teeth of the bidirectional misaligned ratchet. A first return spring is sleeved on the wedge frame. One end of the first return spring is connected to the wedge frame, and the other end is connected to the guide block.

[0008] Furthermore, it also includes a compression assembly, which includes a compression ring. The compression ring is slidably connected within the mounting bracket. The compression ring is located on both the front and rear sides of the lead screw. A rubber pad is connected to the side of the compression ring that contacts the lead screw. A second return spring is sleeved on the side of the compression ring that is away from the lead screw. One end of the second return spring is connected to the mounting bracket, and the other end is connected to the compression ring.

[0009] Furthermore, a cover plate is connected to the top of the mounting bracket, and the cover plate closes the top opening of the compression assembly.

[0010] Furthermore, a roller is installed on the side of the guide block that contacts the conversion ring frame, and the roller rolls and rubs against the inner side of the conversion ring frame.

[0011] Furthermore, the card plate is connected to two identification cards, which correspond to the limiting holes.

[0012] Furthermore, the mounting bracket base plate has several heat dissipation holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By cooperating with the bidirectional staggered ratchet in the conversion assembly, the conversion ring frame, and the bolt rod, a unidirectional transmission control is formed, so that the lead screw can only be driven in one direction, avoiding abnormal movement of the equipment due to misoperation, and achieving the purpose of adjusting the height of the vehicle power amplifier and making the operation intuitive.

[0015] 2. By combining the compression ring, rubber pad and second return spring in the compression assembly, an elastic clamping and shockproof function is formed, which limits the rotation of the lead screw caused by vehicle vibration, so as to achieve the purpose of fixing and stabilizing the height of the vehicle power amplifier and resisting vibration interference.

Detailed Implementation

[0024] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0025] Example: A height-adjustable car amplifier, such as Figures 1-6As shown, the system includes a vehicle amplifier 1, a mounting bracket 2, a connecting bracket 3, a lead screw 4, a guide rod 5, a fixed base 6, an adjusting column 7, a clamping plate 8, and a conversion assembly. The mounting bracket 2 is fixed inside the vehicle. On one side of the mounting bracket 2, a guide rod 5 is fixedly connected, and on the other side, a lead screw 4 is rotatably connected. The connecting bracket 3 is slidably connected inside the mounting bracket 2. One connecting bracket 3 is slidably connected to the guide rod 5, and the other is threadedly connected to the lead screw 4. The vehicle amplifier 1 is mounted on two connecting brackets 3. The parallel arrangement of the guide rod 5 and the lead screw 4 ensures that the connecting bracket 3 remains straight during lifting. The combination of sliding and threaded connections separates the guiding and transmission functions, improving adjustment stability. A fixed base 6 is connected to the top of the mounting bracket 2. An adjusting column 7 is rotatably connected to the top of the fixed base 6. The adjusting column 7 is located on top of the lead screw 4, and a clamping plate 8 is connected to the top of the adjusting column 7. The clamping plate 8 has two limiting holes 9. A conversion assembly for controlling the rotation direction of the lead screw 4 is located inside the fixed base 6. Among them, the fixed base 6 serves as a support base, and the rotational connection design between the adjusting column 7 and the clamping plate 8 realizes centralized control of the transmission path. The two limit holes 9 correspond to different adjustment directions to avoid operational confusion.

[0026] like Figures 3-5 As shown, the conversion assembly includes a conversion ring frame 10, a bolt 11, a docking piece 12, a bidirectional misaligned ratchet 13, a limiting ring 1301, a guide block 14, a wedge frame 15, and a first return spring 16. The conversion ring frame 10 is slidably connected to the adjusting column 7. A block passing through the adjusting column 7 is provided at the top of the conversion ring frame 10. The bolt 11 passes through the block and is slidably connected to the limiting hole 9. The bolt 11 is interference-fitted with the locking plate 8. Several docking pieces 12 are connected around the inner side of the conversion ring frame 10. A bidirectional misaligned ratchet 13 is connected to the top of the lead screw 4. A limiting ring 1301 is connected in the middle. Both guide blocks 14 are equipped with extension plates that are slidably connected to the limiting ring 1301. The guide blocks 14 are vertically slidably connected to the docking member 12. A wedge-shaped frame 15 is slidably connected to the side of the guide block 14 facing the bidirectional misaligned ratchet 13. The side of the guide block 14 away from the bidirectional misaligned ratchet 13 is slidably connected to the conversion ring frame 10. The wedge-shaped frame 15 engages with the ratchet teeth of the bidirectional misaligned ratchet 13. A first return spring 16 is fitted onto the wedge-shaped frame 15, with one end connected to the wedge-shaped frame 15 and the other end connected to the guide block 14. The bidirectional misaligned ratchet 13 uses two ratchet teeth with different directions. Clockwise, the ratchet teeth push the wedge-shaped frame 15 directly, while counterclockwise, the ratchet teeth press the wedge-shaped frame 15 back, achieving unidirectional transmission control. The conversion ring frame 10 is slidably connected to the guide block 14 via the docking member 12, supporting rapid switching of transmission direction and improving operational efficiency.

[0027] like Figure 6 and Figure 7As shown, the system also includes a compression assembly 17, which comprises a compression ring 1701, a rubber pad 1702, and a second return spring 1703. The compression ring 1701 is slidably connected within the mounting bracket 2, located on both the front and rear sides of the lead screw 4. The rubber pad 1702 is connected to the side of the compression ring 1701 that contacts the lead screw 4, while the second return spring 1703 is fitted onto the side of the compression ring 1701 that is away from the lead screw 4. One end of the second return spring 1703 is connected to the mounting bracket 2, and the other end is connected to the compression ring 1701. The second return spring 1703 pushes the compression ring 1701 to clamp the lead screw 4, and the elastic deformation of the rubber pad 1702 provides frictional resistance, effectively limiting the rotation of the lead screw 4 caused by vehicle vibration and ensuring a fixed height.

[0028] like Figure 6 As shown, it also includes a cover plate 18, which is connected to the top of the mounting bracket 2. The cover plate 18 closes the top opening of the compression assembly 17. The cover plate 18 covers the opening of the compression assembly 17 to prevent dust and debris from entering and affecting the performance of the second return spring 1703, while also isolating it from a humid environment and extending the service life of the metal parts.

[0029] like Figure 5 As shown, it also includes a roller 19. The roller 19 is installed on the side of the guide block 14 that contacts the conversion ring frame 10, and the roller 19 rolls against the inner side of the conversion ring frame 10. The roller 19 converts sliding friction into rolling friction, reducing the frictional resistance between the guide block 14 and the conversion ring frame 10, and ensuring a smooth and uninterrupted transmission process.

[0030] like Figure 3 As shown, it also includes identification cards 20. Two identification cards 20 are connected to the card plate 8, and the identification cards 20 correspond to the limiting holes 9. The identification cards 20 clearly indicate the adjustment direction corresponding to the limiting holes 9, such as "↑" for raising and "↓" for lowering, to avoid misjudgment by operators and improve ease of use.

[0031] like Figure 2 As shown, it also includes heat dissipation holes 21, and the base plate of the mounting bracket 2 has several heat dissipation holes 21. Among them, the heat dissipation holes 21 form an air convection channel, which accelerates the heat dissipation at the bottom of the vehicle power amplifier 1, avoids local overheating from affecting the performance of electronic components, and extends the service life of the equipment.

[0032] The installer first fixes the vehicle amplifier 1 to the two connecting brackets 3. Then, based on the preset installation position of the vehicle amplifier 1, the installer assesses the interior space and confirms the fixed position of the mounting bracket 2. By manually controlling the longitudinal position of the vehicle amplifier 1 within the mounting bracket 2, and referring to the corresponding relationship of the limiting holes 9 marked on the identification card 20 ("↑" represents lifting and "↓" represents lowering), the installer determines the required adjustment direction. If it is necessary to lift the vehicle amplifier 1, the installer inserts the bolt 11 into the limiting hole 9 corresponding to the "↑" mark. At this time, the conversion ring 10 slides synchronously within the mounting bracket 2, and its inner connecting part 12 completes longitudinal docking with the upper guide block 14, providing a connection basis for subsequent transmission.

[0033] When the screw 4 needs to be rotated clockwise, the installer pulls the conversion ring frame 10 upwards so that its top block aligns with the hole in the adjusting column 7. At this time, the bolt 11 passes through the block of the conversion ring frame 10 and inserts into the upper limiting hole 9. The docking piece 12 docks with the upper guide block 14. Then, the clamping plate 8 is rotated, which drives the adjusting column 7 and the conversion ring frame 10 to rotate clockwise synchronously. The rotational force is transmitted to the upper guide block 14 through the docking piece 12. The wedge frame 15 contacts the straight ratchet teeth of the top ratchet of the bidirectional misaligned ratchet 13, pushing the bidirectional misaligned ratchet 13 to rotate clockwise. The straight surface of the bottom ratchet teeth of the bidirectional misaligned ratchet 13 connects with the bottom wedge frame 15, pushing the bottom wedge frame 15 to rotate clockwise. At the same time, the limiting ring 1301 provides radial support to the guide block 14 to ensure that the bidirectional misaligned ratchet 13 and the wedge frame 15 rotate stably. When the lead screw 4 rotates clockwise, the threaded connecting bracket 3 rises along the axis of the lead screw 4, driving the vehicle amplifier 1 to rise. The other connecting bracket 3 slides along the guide rod 5, maintaining the balance during the lifting process. If the lead screw 4 is rotated counterclockwise, when the upper guide block 14 rotates with the conversion ring frame 10, the inclined ratchet teeth of the bidirectional misaligned ratchet 13 will squeeze the wedge frame 15, forcing the wedge frame 15 to compress the first return spring 16 and retract along the inner side of the guide block 14. It cannot form an effective engagement with the ratchet teeth, so the lead screw 4 cannot be driven counterclockwise. Since there is no connecting part 12 between the bottom guide block 14 and the conversion ring frame 10, the two slide relative to each other, thus preventing counterclockwise rotation and ensuring the unidirectional adjustment of the vehicle amplifier 1.

[0034] When it is necessary to lower the vehicle amplifier 1, the installer first pulls out the bolt 11, lowers the conversion ring 10 to its original position, aligns the square hole with the lower limit hole 9, and reinserts the bolt 11. At this time, the conversion ring 10 is connected with the lower guide block 14. Rotating the clamping plate 8 counterclockwise will drive the lead screw 4 to rotate counterclockwise, and the connecting frame 3 will descend along the axis of the lead screw 4, causing the vehicle amplifier 1 to fall smoothly back down. The other connecting frame 3 slides in the opposite direction along the guide rod 5 to maintain the stability of the lifting and lowering.

[0035] During the rotation of the lead screw 4, the rubber pad 1702 of the compression ring 1701 forms elastic friction with the surface of the lead screw 4. When the adjustment stops, the second return spring 1703 pushes the compression ring 1701 towards the lead screw 4. After being compressed, the rubber pad 1702 generates radial clamping force, restricting the free rotation of the lead screw 4 caused by vehicle vibration, and ensuring that the installation height of the vehicle amplifier 1 is fixed. The cover plate 18 covers the top of the mounting bracket 2, sealing the opening of the compression assembly 17 to prevent dust and debris from entering and affecting the elastic performance of the second return spring 1703, while also preventing internal metal parts from rusting due to moisture. When the guide block 14 slides along the conversion ring frame 10, the roller 19 rolls in contact with the inner side of the conversion ring frame 10, converting sliding friction into rolling friction, reducing transmission resistance, and ensuring a smooth adjustment process. The heat dissipation holes 21 on the bottom plate of the mounting bracket 2 form an air convection channel, accelerating the heat dissipation generated by the vehicle amplifier 1 during operation, and preventing local overheating from affecting the performance of electronic components.
