Description

Technical Field

[0001] This utility model belongs to the technical field of automotive amplifier components, specifically an automotive amplifier mounting bracket. Background Technology

[0002] A car amplifier, also known as a vehicle amplifier, selects and preprocesses the audio input signal, amplifies it, and enables the electrical signal to drive the speakers. Car amplifiers differ slightly from those in home theaters. Because many car head units integrate power amplification, acting as a pre-amplifier, car amplifiers are sometimes called power amplifiers, meaning they can connect to pre-amplified high-level inputs.

[0003] Car amplifiers require a mounting bracket during installation and use. For example, Chinese patent CN205611122U discloses a mounting bracket for attaching the amplifier tightly to a radiator and vertically mounting it onto a printed circuit board. The mounting bracket includes a flat plate, a pair of legs extending forward from the flat plate and perpendicular to it, a pair of snap-fit ​​structures bent backward from both sides of the flat plate and arranged opposite each other, a pair of blocking parts extending backward from the top of the flat plate, and an elastic arm located in the middle of the flat plate. The mounting bracket limits and positions the amplifier, ensuring it is tightly attached to the radiator. This design saves significant labor and fixture costs during manufacturing, simplifies production steps, and greatly reduces production costs. While this patent saves considerable labor and fixture costs during manufacturing, it does not provide complete fixation for the car amplifier, leading to wobbling during use and affecting normal operation. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a car amplifier mounting bracket that is easy to use and solves the problem of inconvenient use of car amplifier mounting brackets.

[0005] This utility model provides the following technical solution: a car amplifier mounting bracket, comprising:

[0006] support plate;

[0007] Upper and lower fixing mechanisms are provided on both sides of the front of the support plate;

[0008] The transmission mechanism includes a forward and reverse threaded rod, which is disposed on the left side of the support plate. Both sides of the surface of the forward and reverse threaded rod are threaded with threaded hole plates. The top and bottom of the threaded hole plates are fixedly connected with sliding sleeves. The front and back of the sliding sleeves are fixedly connected with sliders. The side of the slider away from the slider passes through the support plate and extends to the outside of the support plate. The inside of the sliding sleeve is slidably connected with a smooth rod, and the two ends of the smooth rod are fixedly connected to the two sides of the inner wall of the support plate, respectively.

[0009] The beneficial effects of this utility model are as follows:

[0010] 1. This utility model, by setting a transmission mechanism, can transmit power to the upper and lower fixing mechanisms and the radiator connecting mechanism, so that the upper and lower fixing mechanisms clamp the two sides of the car amplifier, and then the protective plates of the upper and lower fixing mechanisms fix the top and bottom of the car amplifier, and then the radiator connecting mechanism fixes the radiator. The car amplifier will not shake during use.

[0011] 2. This utility model can fix the top and bottom of the car amplifier by setting up an upper and lower fixing mechanism. The bolt is installed inside the protective plate through the fixing bearing, and then the bolt is inserted into the inside of the clamping plate, so that the clamping plate fixes the protective plate through the bolt and the fixing bearing. Then, the bolt is rotated, and the bolt drives the protective plate to move closer to the car amplifier through the fixing bearing, thus clamping the top and bottom of the car amplifier.

[0012] 3. This utility model can dissipate heat from the car amplifier on the bracket plate by setting up a heat sink. The fan housing is installed inside the frame, and the fan blades are installed inside the fan housing. The fan housing drives the fan blades through the power source to rotate the fan blades. The rotation of the fan blades blows out air, which is blown into the car amplifier through the through hole and the heat dissipation hole on the back of the car amplifier to dissipate heat from the car amplifier.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figures 1 to 6 As shown, the car amplifier mounting bracket in this embodiment includes a bracket plate 1, upper and lower fixing mechanisms 2, and a transmission mechanism 3. The bracket plate 1 is made of anti-slip rubber. The upper and lower fixing mechanisms 2 are located on both sides of the front of the bracket plate 1. The transmission mechanism 3 includes a positive and negative threaded rod 31, which is located on the left side of the bracket plate 1.

The side of the sliders 34 away from the sliders 34 penetrates the bracket plate 1 and extends to the outside of the bracket plate 1. The inside of the sliding sleeves 33 is slidably connected with a smooth rod 35. The two ends of the smooth rod 35 are fixedly connected to the two sides of the inner wall of the bracket plate 1, respectively. The two sides of the smooth rod 35 are fixedly connected with reinforcing sleeves to increase the connection area between the smooth rod 35 and the inner wall of the bracket plate 1.

[0021] refer to Figure 2 The upper and lower fixing mechanism 2 includes a clamping plate 21. The front of the slider 34 is fixedly connected to the back of the clamping plate 21. The top and bottom of the clamping plate 21 are provided with protective plates 22. The outer side of the protective plate 22 is provided with bolts 23. The inner side of the bolts 23 penetrates the protective plate 22 and extends into the interior of the clamping plate 21.

[0022] In this embodiment, by setting up upper and lower fixing mechanisms 2, the top and bottom of the car amplifier 6 can be fixed. The bolt 23 is installed inside the protective plate 22 through the fixing bearing 7, and then the bolt 23 is inserted into the clamping plate 21, so that the clamping plate 21 fixes the protective plate 22 through the bolt 23 and the fixing bearing 7. Then, the bolt 23 is rotated, and the bolt 23 drives the protective plate 22 to move closer to the car amplifier 6 through the fixing bearing 7, thus clamping the top and bottom of the car amplifier 6.

[0023] refer to Figure 6 A radiator 4 is provided on the back of the support plate 1. The radiator 4 includes a frame 41. A fan housing 42 is provided on the front of the frame 41. A fan blade 43 is movably installed inside the fan housing 42. A power source is installed inside the fan housing 42. The output end of the power source is fixedly connected to the fan blade 43.

[0024] In this embodiment, by setting up a heat sink 4, the car amplifier 6 on the bracket plate 1 can be cooled. The fan housing 42 is installed inside the frame 41, and the fan blades 43 are installed inside the fan housing 42. The fan housing 42 drives the fan blades 43 through a power source, causing the fan blades 43 to rotate. The rotation of the fan blades 43 blows out air, which is blown into the car amplifier 6 through the through hole 9 and the heat dissipation hole on the back of the car amplifier 6 to cool the car amplifier 6.

[0025] refer to Figure 5 Both sides of the back of the support plate 1 are provided with heat sink connection mechanisms 5. The heat sink connection mechanism 5 includes a connecting rod 51. The front of the connecting rod 51 is fixedly connected to the back of the slider 34. A fixing plate 52 is fixedly connected to the side of the connecting rod 51 away from the slider 34. A transmission screw 53 is provided on the outer side of the fixing plate 52. The inner side of the transmission screw 53 passes through the fixing plate 52 and extends to the inner side of the fixing plate 52, where a fixing bearing 54 is fixedly connected. A clamping plate 55 is fixedly connected to the inner side of the outer ring of the fixing bearing 54. The inner side of the clamping plate 55 contacts the frame 41. The transmission screw 53 is threadedly connected to the inside of the fixing plate 52.

[0026] In this embodiment, the radiator 4 can be fixed by setting the radiator connection mechanism 5. Rotating the transmission screw 53 will cause the transmission screw 53 to move closer to the radiator 4 because the transmission screw 53 is threadedly connected to the fixing plate 52. The transmission screw 53 will drive the fixing bearing 54 to move closer to the radiator 4, and the fixing bearing 54 will drive the clamping plate 55 to move closer to the radiator 4 to fix both sides of the radiator 4.

[0027] refer to Figure 1 An automotive amplifier 6 is provided on the inner side of the bracket plate 1. The automotive amplifier 6 includes a housing 61. A cable connector 62 is fixedly connected to the top of the housing 61, and a base 63 is fixedly connected to the bottom of the housing 61. The surface of the housing 61 is in contact with the inner side of the clamping plate 21.

[0028] In this embodiment, by setting up the car amplifier 6, it can be connected to an external connection cable. The housing 61 is installed on the top of the base 63, and then the cable connector 62 is installed on the top of the housing 61. After completion, the connection cable is installed on the top of the cable connector 62, and then the housing 61 transmits data to the inside of the connection cable through the cable connector 62.

[0029] refer to Figure 2 A fixed bearing 7 is fixedly connected to the surface of bolt 23, and the surface of the outer ring of the fixed bearing 7 is fixedly connected to the inner wall of the protective plate 22.

[0030] In this embodiment, by setting a fixed bearing 7, the bolt 23 can be fixed so that the bolt 23 is connected to the protective plate 22.

[0031] refer to Figure 3 Both sides of the surface of the positive and negative threaded rod 31 are fixedly connected to a sealing structure 8. The surface of the outer ring of the sealing structure 8 is fixedly connected to the inner wall of the support plate 1. The sealing structure 8 is a sealed bearing.

[0032] In this embodiment, by setting a sealing structure 8, the gap between the positive and negative threaded rod 31 and the support plate 1 can be sealed to prevent air inside the support plate 1 from leaking out from the gap between the positive and negative threaded rod 31 and the support plate 1.

[0033] refer to Figure 1 The front of the support plate 1 has a through hole 9, and the back of the through hole 9 is connected to the fan casing 42.

[0034] In this embodiment, by providing a through hole 9, the air blown out by the rotation of the fan blade 42 can be guided, so that the air enters the interior of the car amplifier 6 from the front of the through hole 9 and the heat dissipation hole on the back of the car amplifier 6.

[0035] refer to Figure 3 The top and bottom of the front and back sides of the support plate 1 are provided with sliding grooves 10, and the interior of the sliding grooves 10 is slidably connected to the surface of the slider 34.

[0036] In this embodiment, by setting the sliding groove 10, the slider 34 can be guided to prevent the slider 34 from wobbling up and down inside the support plate 1.

[0037] Place the car amplifier 6 on the front of the bracket plate 1, then rotate the positive and negative threaded screw 31. The positive and negative threaded screw 31 drives the screw hole plate 32 to move inward, the screw hole plate 32 drives the sliding sleeve 33 to move inward, the sliding sleeve 33 drives the slider 34 to move inward on the surface of the smooth rod 35, and the slider 34 drives the clamping plate 21 in the upper and lower fixing mechanism 2 to move towards the side of the car amplifier 6, clamping the car amplifier 6 through the clamping plate 21. After completion, rotate the bolt 23, the bolt 23 drives the protective plate 22 to move towards the side of the car amplifier 6, limiting the top and bottom of the car amplifier 6 through the protective plate 22. Then install the radiator 4. Installed on the back of bracket plate 1, the transmission screw 53 is rotated. Since the transmission screw 53 is threadedly connected to the fixing plate 52, the rotation of the transmission screw 53 will move it closer to the radiator 4. The transmission screw 53 drives the fixing bearing 54 to move closer to the radiator 4. The fixing bearing 54 drives the clamping plate 55 to move closer to the radiator 4 to fix both sides of the radiator 4. The fan housing 42 drives the fan blade 43 to rotate, and the rotation of the fan blade 43 blows out air. The air is blown into the interior of the car amplifier 6 through the through hole 9 and the heat dissipation hole on the back of the car amplifier 6 to dissipate heat from the car amplifier 6.
