Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a reversing buzzer assembly. Background Technology

[0002] A reversing buzzer typically consists of a signal generator, a signal amplifier, and a buzzer horn. Its output is an intermittent single tone. It uses a signal generator to generate a signal, which is amplified by a power amplifier and then released through the buzzer horn to achieve a warning purpose. A search revealed that Chinese Patent Publication No. CN221775763U discloses a reversing buzzer assembly, which relates to the field of automotive parts. It includes a mounting housing, a buzzer body, and a protective cover. The mounting housing has a mounting groove in the middle, and the buzzer body is snapped into the mounting groove. The inner wall of the mounting groove end face is provided with a snap-fit ​​component for fixing the buzzer body. The snap-fit ​​component includes an annular rotating ring, a snap block, and a connecting rod. The protective cover is threaded to the outer wall of the top of the mounting housing.

[0003] While the above-mentioned technical solution facilitates the disassembly and assembly of the buzzer body and enables vibration damping in all directions, during use, the buzzer is mounted on the vehicle frame in a confined space. Therefore, although the above-mentioned technical solution can open the protective cover, the limited space makes it inconvenient to pull out and install the buzzer body, thus affecting maintenance efficiency. Furthermore, it only provides cushioning protection through the inner rubber layer, which has limited cushioning effect. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example:

[0023] like Figures 1 to 6 As shown in the figure, a reversing buzzer assembly includes a base plate 1. Both ends of the base plate 1 are pierced by fixing bolts 2 for mounting the reversing buzzer on the vehicle frame. A fixing ring 3 is fixedly connected to the upper surface of the base plate 1. A housing 4 is inserted into the inside of the fixing ring 3. A fixing mechanism for fixing the housing 4 is installed on the fixing ring 3. A top cover 5 is threadedly connected to the top of the housing 4. The reversing buzzer body 6 is located inside the housing 4. The fixing mechanism includes grooves 10 arranged in a ring array around the outer surface of the fixing ring 3. A rod 7 is slidably connected through the grooves 10. Multiple insertion holes 8 that mate with the rod 7 are provided on the outer surface of the housing 4. A positioning ring 9 is threadedly connected to the outer surface of the fixing ring 3. The internal cross-sectional shape of the positioning ring 9 is trapezoidal. A limiting plate 11 is fixedly connected to the outer surface of the rod 7 and slidably connected to the inner wall of the groove 10. A return spring 12 is provided between the limiting plate 11 and the inner wall of the groove 10. A positioning block 13 is fixedly connected to the upper surface of the base plate 1. A positioning hole that mates with the positioning block 13 is provided at the bottom of the housing 4.

[0024] In use, the base plate 1 and the entire reversing buzzer assembly can be installed on the vehicle frame using the fixing bolts 2 on the base plate 1. In this technical solution, the reversing buzzer body 6 is connected to the vehicle power supply and controller via wires to realize the reminder function. When the reversing buzzer body 6 needs to be repaired or replaced, simply rotate the positioning ring 9. Under the action of the thread, the positioning ring 9 moves and causes one end of the plug rod 7 to lose its restraint. At this time, under the action of the return spring 12, one end of the plug rod 7 can be moved out of the plug hole 8, and then the outer shell 4 and the reversing buzzer body 6 can be removed. Conversely, during installation, simply insert the outer shell 4 into the fixing ring 3, and then rotate the positioning ring 9 to drive the plug rod 7 to move and insert it into the plug hole 8, thereby fixing the outer shell 4 and the reversing buzzer body 6. The operation is convenient and simple.

[0025] like Figure 1 , Figure 5 and Figure 6 As shown, a protective mounting mechanism for fixing the reversing buzzer body 6 is installed inside the outer casing 4. The protective mounting mechanism includes a buffer spring 14 and a damper that are sequentially fixedly connected to the bottom of the inner casing 4. A connecting plate 15 is fixedly connected to the top of the buffer spring 14 and the damper. A rubber pad 16 is fixedly connected to the top of the connecting plate 15. The top of the rubber pad 16 has a slot for placing the reversing buzzer body 6. A rubber sleeve 17 is fixedly connected to the inner wall of the outer casing 4. The connecting plate 15 contacts the inner wall of the rubber sleeve 17. A mounting ring 18 is fixedly connected to the inner wall of the rubber sleeve 17. The mounting ring 18 is sleeved on the outside of the reversing buzzer body 6. Two elastic buckles 19 are symmetrically fixedly connected to the outer surface of the reversing buzzer body 6. The outer surface of the mounting ring 18 has a groove that mates with the elastic buckles 19. The bottom end of the elastic buckle 19 extends to the bottom of the mounting ring 18.

[0026] The reversing buzzer body 6 can be installed in a relatively enclosed space by the outer shell 4 and top cover 5, which can avoid damage from direct impact. The elastic buckle 19 facilitates the fixing and disassembly of the reversing buzzer body 6. When vibration occurs, the buffer spring 14 and damper can buffer and protect the vertical vibration of the reversing buzzer body 6, and the rubber sleeve 17 can buffer and protect the circumferential vibration of the reversing buzzer body 6. Thus, the reversing buzzer body 6 can be fully protected to avoid damage due to vibration and improve its service life.

[0027] A through hole is provided at the center of the top of the top cover 5. A dustproof net and a waterproof membrane are embedded inside the through hole. The dustproof net and waterproof membrane can prevent dust and rainwater from entering, thus improving the protection effect.

[0028] Working principle: During use, the base plate 1 and the entire reversing buzzer assembly can be installed on the vehicle frame using the fixing bolts 2 on the base plate 1. In this technical solution, the reversing buzzer body 6 is connected to the vehicle power supply and controller via wires to realize the reminder function. When the reversing buzzer body 6 needs to be repaired or replaced, simply rotate the positioning ring 9. Under the action of the thread, the positioning ring 9 moves and causes one end of the insertion rod 7 to lose its restraint. At this time, under the action of the return spring 12, one end of the insertion rod 7 can be moved out of the insertion hole 8, and then the outer shell 4 and the reversing buzzer body 6 can be removed. Conversely, during installation, simply insert the outer shell 4 into the fixing ring 3, and then rotate the positioning ring 9 to drive the insertion rod 7 to move and insert it into the insertion hole 8, thereby fixing the outer shell 4 and the reversing buzzer body 6. The operation is convenient and simple.

[0029] The reversing buzzer body 6 can be installed in a relatively enclosed space by the outer shell 4 and top cover 5, which can avoid damage from direct impact. The elastic buckle 19 facilitates the fixing and disassembly of the reversing buzzer body 6. When vibration occurs, the buffer spring 14 and damper can buffer and protect the vertical vibration of the reversing buzzer body 6, and the rubber sleeve 17 can buffer and protect the circumferential vibration of the reversing buzzer body 6. Thus, the reversing buzzer body 6 can be fully protected to avoid damage due to vibration and improve its service life.
