Description

Technical Field

[0001] The utility model relates to a module, in particular to a vehicle-mounted audio chip module, belonging to the technical field of vehicle-mounted chips. Background Art

[0002] The car audio chip is a chip module unit that provides music for the vehicle and provides power amplification and other functions for the car audio. Since the car audio chips that come with the original car central control system are integrated chips with relatively simple functions, when upgrading these audio chips, in order not to change the relevant lines of the original central control, the main form of external car audio chip modules is adopted, which are connected to the original central control motherboard and audio external devices such as car audio through an independent module structure and an audio interface. The independent module structure needs to be placed in the cavity on the rear side of the central control. Since there is no relevant installation position designed in the original car, it is necessary to solve the installation problem of the car audio chip module. At present, the conventional installation is direct placement or bolt installation. Direct placement of the module is easy to move in the central control cavity, causing the interface to loosen or be damaged, and bolt installation requires drilling in the central control cavity, which is cumbersome and easy to damage the original car direct structure.

[0018] In order to elaborate on the technical scheme adopted by the utility model to achieve the predetermined technical purpose, the technical scheme in the embodiment of the utility model will be clearly and completely described in combination with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a partial embodiment of the utility model, not all of the embodiments, and the technical means or technical features in the embodiment of the utility model can be replaced without paying creative labor. The utility model will be described in detail with reference to the drawings and in combination with the embodiments.

[0019] like Figure 1 As shown, a vehicle audio chip module of the utility model comprises an external vehicle audio chip device body 1 and a mounting back plate 2, and a clamp fixing mechanism is arranged at the rear side of the mounting back plate 2. Figure 3 As shown, a plurality of T-shaped sliders 3 are arranged on the rear side of the external vehicle audio chip device body 1, and locking grooves are arranged on the mounting back plate 2 corresponding to the T-shaped sliders 3 on the rear side of the external vehicle audio chip device body 1. Figure 2 As shown, the locking groove includes a wide groove 4, a narrow groove 5 and a locking plate 6. The lower end of the wide groove 4 is connected to the upper end of the narrow groove 5. The locking plate 6 is arranged in the wide groove 4 and one end of the locking plate 6 is fixedly connected to the upper end of the wide groove 4. The lower end of the locking plate 6 is suspended at the upper end of the narrow groove.

[0020] like Figure 3 As shown, four T-shaped sliders 3 are provided, and the four T-shaped sliders 3 are distributed in a rectangular shape on the rear side surface of the external vehicle audio chip device body 1 .

[0021] like Figure 2 As shown, there are four locking slide grooves, which are distributed in a rectangular shape on the mounting back plate 2 and the positions of the four locking slide grooves correspond to the positions of the four T-shaped slide blocks 3. When the external vehicle audio chip device body 1 is installed in the locking slide grooves through the T-shaped slide blocks 3, the rear side of the external vehicle audio chip device body 1 just overlaps with the mounting back plate 2.

[0022] like Figure 2 As shown, the width of the wide groove 4 is slightly greater than or equal to the maximum width of the T-shaped slider 3 (i.e., the width of the T-shaped slider in the horizontal direction), the width of the narrow groove 5 is slightly greater than or equal to the minimum width of the T-shaped slider 3 (i.e., the width of the vertical portion of the T-shaped slider), and the width of the narrow groove 5 is less than the maximum width of the T-shaped slider 3. During installation, the T-shaped slider 3 is first inserted into the wide groove 4 from the front to the back, and then moved vertically downward to slide the T-shaped slide 3 downward into the narrow groove 5.

[0023] The width of the locking piece 6 is equal to that of the narrow groove 5, and the locking piece 6 is located in the middle of the wide groove 4. The length of the locking piece 6 is equal to that of the wide groove 4, and the length of the narrow groove 5 is equal to that of the T-shaped slider 3. In this way, when the T-shaped slider 3 is inserted into the wide groove 4, the locking piece 6 is pressed down, and when the T-shaped slider 3 slides into the narrow groove 5, the locking piece 6 rebounds and resets to lock the upper side of the T-shaped slider 3, preventing the T-shaped slider 3 from sliding upward and falling off in the narrow groove 5. When disassembling, the locking piece 6 only needs to be moved downward to slide the T-shaped slider 3 upward into the wide groove 4 and pull it out.

[0024] like Figure 4 As shown, the clamp fixing mechanism comprises a first clamp sheet 7, a second clamp sheet 8, a bolt 9 and a nut 10, one end of the first clamp sheet 7 is hinged on the rear side of the mounting back plate 2, one end of the second clamp sheet 8 is hinged on the rear side of the mounting back plate 2, and the first clamp sheet 7 and the second clamp sheet 8 are symmetrically arranged at the center of the rear side of the mounting back plate 2, the other ends of the first clamp sheet 7 and the second clamp sheet 8 are provided with screw holes matching the bolt 9, one end of the bolt 9 passes through the screw holes of the first clamp sheet 7 and the second clamp sheet 8 and is locked and fixed by the nut 10. The first clamp sheet 7 and the second clamp sheet 8 are made of metal sheets or polyester sheets with good elasticity, so that the two clamp sheets have a certain deformation amount when installed to adapt to internal structures or wiring harnesses of different thicknesses. The first clamp sheet 7 and the second clamp sheet 8 have a certain distance from the connection position of the mounting back plate 2, so that the width between the two clamp sheets is large enough to be installed on some large-diameter vehicle body structures.

[0025] The main parts of the first clamp sheet 7 and the second clamp sheet 8 are arc-shaped, and the other ends of the first clamp sheet 7 and the second clamp sheet 8 are provided with straight portions, and screw holes are opened on the straight portions of the other ends of the first clamp sheet 7 and the second clamp sheet 8. The ends of the clamp sheets are designed to be in a straight shape, so that it is more convenient to install the bolts 9.

[0026] An aluminum alloy heat sink fin plate 11 is provided on the front side of the external vehicle audio chip device body 1 to facilitate heat dissipation of the audio chip circuit inside the entire external vehicle audio chip device body 1 .

[0027] The utility model provides a vehicle-mounted audio chip module, which has a structural design of an independent mounting back plate. The mounting back plate can be locked on a vehicle body structure or even a central control wiring harness by means of clamps and bolts. Then, an external vehicle-mounted audio chip device body is detachably connected to a locking slide groove structure by means of a T-shaped slider. The locking plate design ensures that the installation is firm, and disassembly and maintenance are also convenient.

[0028] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent replacement and improvement of the above embodiments made according to the technical essence of the present invention, within the spirit and principles of the present invention, without departing from the content of the technical solution of the present invention, still fall within the protection scope of the technical solution of the present invention.
