Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted power amplifiers, in particular to an automobile power amplifier heat dissipation device with a warning function. Background Technique

[0002] A vehicle-mounted power amplifier refers to a power amplifier system installed in a vehicle. The most basic condition for the system to be called a power amplifier is that it has the function of playing back sound. Its anti-interference technology is to use a choke coil in series between the power supply and the power amplifier to filter the interference of the power line, so as to reduce external noise interference. For a vehicle-mounted CD power amplifier system, the laser head is the most expensive and vulnerable part in the CD. Taking good care of the power amplifier can effectively extend the service life of the laser head and enable the vehicle-mounted power amplifier system to ensure high-quality music playback for a long time. The vehicle-mounted power amplifier comprehensively integrates multimedia entertainment functions, satellite navigation functions, wireless communication and mobile office systems, auxiliary driving systems, and active safety systems and other vehicle-mounted terminals, and has relevant infinite expandability. With the continuous progress of social technology and the continuous improvement of people's living standards, cars have become popular in people's lives. Now cars have become an essential means of transportation for people. As an important automobile accessory, the vehicle-mounted power amplifier can bring people a pleasant mood and relieve driving fatigue when driving.

[0003] For example, the patent document with the publication number 202222711255.1 discloses a power amplifier heat dissipation device, including a power amplifier box mechanism. An upper cover mechanism is arranged on the upper side of the power amplifier box mechanism. The power amplifier box mechanism includes a power amplifier box. A circuit board is arranged inside the power amplifier box. The power amplifier box includes a power amplifier box body, a plurality of heat dissipation fans and a plurality of dust covers. Support strips are arranged on the front and rear side walls inside the power amplifier box body. A plurality of first threaded rods are arranged on the upper side of a group of support strips. A group of wire holes are opened on the rear side wall inside the power amplifier box body above the support strips. Fixed clamping strips are arranged at the lower ends of the front and rear sides of the power amplifier box body. A group of dust removal grooves are opened at the bottom end inside the power amplifier box body. A group of fan positioning grooves are opened at the left and right ends inside the power amplifier box body. A positioning clamping strip is arranged on one side of the heat dissipation fan.

[0004] The above device can discharge foreign matters entering the inside of the power amplifier box body through a group of dust removal grooves, so as to avoid the situation that it is difficult to remove foreign matters after they enter. Through a group of wire holes, the connection between the outside and the internal wires of the power amplifier box body can be facilitated. After the screw penetrates through the fixed clamping strip, the power amplifier box body can be fixed at a specified position, which is convenient for installation. At present, when the vehicle-mounted power amplifier is in use, the vibration is large and the played sound quality is not good. It not only cannot relieve fatigue, but also has noise and is rather harsh. Therefore, we propose an automobile power amplifier heat dissipation device with a warning function.

[0026] Please refer to Figures 1-4 As shown, this embodiment is an automotive power amplifier heat dissipation device with a warning function, including a mounting plate 1 and a connecting plate 7. A fixing bolt 2 is provided inside the mounting plate 1, a protective cylinder 3 is provided outside the mounting plate 1, a sound outlet hole 4 is opened at the top of the protective cylinder 3, a heat dissipation net 5 is provided inside the protective cylinder 3, a fixture 8 is provided at the top of the connecting plate 7, a power amplifier body 9 is provided at the top of the connecting plate 7, and further includes: a protection mechanism: The protection mechanism includes a sliding groove 13 provided inside the connecting plate 7, a shock absorption component is provided inside the sliding groove 13, and a connecting component is provided at the top of the mounting plate 1.

[0027] As the main body bearing structure, the protection mechanism can increase the protection and shock absorption of the overall structure by being fixedly connected to the whole device.

[0028] The shock absorption component includes a connecting frame 14 provided inside the sliding groove 13, a second shaft rod 15 is provided on the inner side wall of the connecting frame 14, a shock absorption spring 17 is provided on the inner side wall of the sliding groove 13, and a damping spring 6 is provided at the bottom end of the connecting plate 7.

[0029] By providing the shock absorption component, it is convenient to buffer and shock-absorb the connecting plate 7 and protect the power amplifier body 9.

[0031] By providing the connecting component, it is convenient to transmit the vibration on the connecting plate 7 into the shock absorption spring 17 and the damping spring 6 through the rotating plate 16.

[0032] Working principle: When the temperature inside the protective cylinder 3 is too high, the high temperature triggers the temperature alarm 10 to give an alarm. At the same time, the cooling fan is started to dissipate heat through the heat dissipation net 5. When the device receives external pressure vibration, the power amplifier body 9 rotates inside the mounting plate 1 through the connecting plate 7. At the same time, the sliding connecting plate 7 squeezes the rotating plate 16 to rotate through the first shaft rod 12. The rotating first shaft rod 12 pushes the connecting frame 14 to slide through the second shaft rod 15. Thus, the connecting frame 14 slides inside the chute 13. The sliding connecting frame 14 squeezes the shock-absorbing spring 17 to slide. At the same time, the sliding connecting plate 7 squeezes the damping spring 6 for protection and vibration reduction.

[0033] This step can facilitate the alarm when the temperature is too high and facilitate the protection of the power amplifier body 9, increasing the safety of use of the power amplifier body 9 and avoiding damage to the power amplifier body 9 caused by impact.
