[0002] With the development of the automotive industry and the increasing demands of consumers for in-car entertainment experiences, car audio systems have become an important part of car interiors. Car lift-up audio systems, as a distinctive product, not only meet consumers' pursuit of high-quality sound but also add a unique sense of technology and ceremony to the car interior.

[0003] Car audio systems utilize a lift bracket, which typically includes a lifting platform, a drive unit, and a guide component. The audio system is fixed to the lifting platform, and the guide component generally employs a guide rod and a guide hole, with the guide rod positioned within the guide hole. However, this structure, using a guide rod and guide hole, has two drawbacks. First, the guidance is not precise enough, easily leading to shaking and noise. Second, because the guide rod and guide hole are made of different materials, thermal expansion and contraction or manufacturing errors can easily cause the guide rod to jam, resulting in poor performance.

Guide sleeves 5 are symmetrically installed on the drive seat 2, and the guide rods 4 pass through the corresponding guide sleeves 5, which can slide relative to the guide rods 4. The guide rods 4 and guide sleeves 5 are both made of metal, while the drive seat 2 is made of plastic.

[0037] See Figure 2 and Figure 5 A receiving groove 201 is provided through the drive seat 2. The guide sleeve 5 is placed in the receiving groove 201, and a gap 202 is formed between the guide sleeve 5 and the inner wall of the receiving groove 201. An elastic component is sleeved on the guide sleeve 5, and the elastic component abuts against the inner wall of the receiving groove 201 under the action of elastic force. The elastic component includes a plurality of rubber rings 6 arranged at intervals along the axis of the guide sleeve 5. A plurality of annular mounting grooves 501 are provided on the outer circumferential wall of the guide sleeve 5, and the rubber rings 6 are placed in the corresponding annular mounting grooves 501. In this embodiment, there are two rubber rings 6 arranged at intervals. The addition of the guide sleeve 5 and the guide rod 4 can ensure the accuracy of the movement and prevent the guide rod from shaking and making noise. With the addition of the receiving groove 201 and the rubber rings 6, the rubber rings 6 abut against the inner wall of the receiving groove 201 under the action of elastic force. When the material undergoes thermal expansion and contraction or processing errors, the elasticity of the rubber rings 6 can eliminate the influence, preventing the guide rod from getting stuck and ensuring the stability and reliability of the structure.

[0038] In some embodiments, such as Figure 4 and Figure 5 As shown, elastic locking heads 203 are symmetrically arranged on the upper side of the receiving groove 201. The elastic locking heads 203 and the drive seat 2 are integral plastic parts. The upper end of the guide sleeve 5 is provided with a locking groove 502 that engages with the elastic locking head 203. An upper limit flange 503 is formed on the upper side of the locking groove 502. The upper limit flange 503 abuts against the elastic locking head 203, thereby limiting the guide sleeve 5. A limiting groove 204 is provided on the lower side of the receiving groove 201. The lower end of the guide sleeve 5 is provided with a lower limiting flange 504 that matches the limiting groove 204. The lower limiting flange 504 is placed in the limiting groove 204, thereby limiting the guide sleeve 5.

[0039] In some embodiments, such as Figure 2 , Figure 8 and Figure 9 As shown, a drive wheel 7 and a lead screw 8 are installed inside the housing 1. The drive wheel 7 is a worm gear, and the lead screw 8 is vertically arranged and driven by the drive seat 2. The drive seat 2 has a threaded hole adapted to the lead screw 8.
