Description
Technical Field
[0001] This utility model belongs to the field of loudspeaker technology, specifically relating to a fixing device for the U-shaped iron and frame of an automotive loudspeaker. Background Technology
[0002] Car speaker U-shaped irons are typically made of iron or other magnetic materials. They work together with the speaker's magnets to create a magnetic field, which in turn affects the speaker's diaphragm (paper cone), thus producing sound. The design and structure of the U-shaped iron have a significant impact on the speaker's performance, including its sensitivity and frequency response.
[0003] Authorized announcement number CN217770350U discloses a fixing mechanism for a speaker U-shaped iron and a speaker frame, including a speaker frame and a U-shaped iron. The U-shaped iron is sleeved on the speaker frame. It also includes a fixing component installed on the speaker frame or the U-shaped iron. The fixing block in the fixing component abuts against the speaker frame or the U-shaped iron and is inserted into both the speaker frame and the U-shaped iron. The upper end of the speaker frame has a first heat dissipation hole and a second heat dissipation hole, both of which are connected to the inner wall of the upper end of the speaker frame. The lower end of the speaker frame has a third heat dissipation hole, a fourth heat dissipation hole, and a fifth heat dissipation hole. The beneficial effects of this utility model are: by setting a fixing component, the insertion post on the fixing block in the fixing component is inserted into the speaker frame, thereby achieving the fixing between the speaker frame and the U-shaped iron. The fixing method is simple to operate, easy to quickly disassemble and assemble, and convenient for later maintenance and repair.
[0004] The aforementioned patent fixes the U-shaped iron and the basin frame by adding a lead screw inside the U-shaped iron. However, since the U-shaped iron and the basin frame are relatively small, adding a lead screw to such delicate components would be somewhat awkward and the installation would be relatively difficult. Furthermore, the lead screw needs to rotate in conjunction with a bearing, and the vibration generated when the car is moving can easily cause the bearing to loosen, thus affecting the reliability of the fixation between the U-shaped iron and the basin frame.

The U-shaped iron body 1 and the frame body 2 are fixedly connected by a U-shaped iron and frame fixing assembly 3, and a U-shaped iron and frame connection sealing assembly 7 is provided at the connection between the U-shaped iron body 1 and the frame body 2.
[0024] Specifically, the U-shaped iron and basin frame fixing assembly 3 includes a fixing hole 31, an insertion hole 34, a fixing rod 35, a mounting block 37, a spring 39, and a sliding plate 310. The lower inner wall of the basin frame body 2 is provided with a mounting block 37, and a spring 39 is installed inside the mounting block 37. The other end of the spring 39 is provided with a sliding plate 310, and the other end of the sliding plate 310 is provided with a fixing rod 35. The lower side of the basin frame body 2 has an insertion hole 34 corresponding to the fixing rod 35, and the side of the U-shaped iron body 1 has a fixing hole 31 corresponding to the fixing rod 35.
[0025] By adopting the above technical solution, when connecting and fixing the U-shaped iron body 1 and the basin frame body 2, first press the fixing rod 35, the fixing rod 35 compresses the sliding plate 310 and the spring 39, and makes the fixing rod 35 embedded in the mounting block 37. Then insert the basin frame body 2 into the U-shaped iron body 1, and then rotate the basin frame body 2. When the insertion hole 34 is aligned with the fixing hole 31, the spring 39 rebounds, thereby driving the fixing rod 35 to be inserted into the fixing hole 31, so as to achieve the fixing of the basin frame body 2 and the U-shaped iron body 1.
[0026] Specifically, the U-shaped iron and basin stand fixing assembly 3 also includes fastening screws 32 and ear plates 33. The ear plates 33 are provided at the side edge of the mounting block 37, and the ear plates 33 are fixedly connected to the inner wall of the basin stand body 2 by fastening screws 32.
[0027] By adopting the above technical solution, the ear plate 33 is fixed to the inner wall of the basin frame body 2 by fastening screw 32, so as to fix the mounting block 37.
[0028] Specifically, the U-shaped iron and basin stand fixing assembly 3 also includes an adjusting block 36 and an adjusting groove 38. The upper end of the sliding plate 310 is provided with the adjusting block 36, and the upper end of the mounting block 37 is provided with an adjusting groove 38 corresponding to the adjusting block 36.
[0029] By adopting the above technical solution, when disassembling the basin frame body 2 and the U-shaped iron body 1, the adjusting block 36 inside the sliding adjustment groove 38 drives the sliding plate 310 to slide, and the sliding plate 310 drives the fixing rod 35 to slide out from the inside of the fixing hole 31, thereby disassembling and separating the basin frame body 2 and the U-shaped iron body 1.
[0030] In this embodiment, the ear plate 33 is fixed to the inner wall of the basin frame body 2 by the fastening screw 32 to fix the mounting block 37. When connecting and fixing the U-shaped iron body 1 and the basin frame body 2, first press the fixing rod 35. The fixing rod 35 compresses the sliding plate 310 and the spring 39, so that the fixing rod 35 is embedded in the mounting block 37. Then insert the basin frame body 2 into the U-shaped iron body 1. Then rotate the basin frame body 2. When the insertion hole 34 is aligned with the fixing hole 31, the spring 39 rebounds, thereby driving the fixing rod 35 to be inserted into the fixing hole 31, so as to fix the basin frame body 2 and the U-shaped iron body 1. When disassembling the basin frame body 2 and the U-shaped iron body 1, slide the adjusting block 36 inside the adjusting groove 38. The adjusting block 36 drives the sliding plate 310 to slide. The sliding plate 310 drives the fixing rod 35 to slide out from the fixing hole 31, so that the basin frame body 2 and the U-shaped iron body 1 can be disassembled and separated.
[0031] Example 2
[0032] The difference between this embodiment and Embodiment 1 is that the sealing assembly 7 connecting the U-shaped iron and the basin frame includes an annular embedding groove 71, an annular embedding groove 72, and a sealing ring 73. A sealing ring 73 is provided between the lower end of the basin frame body 2 and the U-shaped iron body 1. An annular embedding groove 71 corresponding to the sealing ring 73 is provided at the lower edge of the U-shaped iron body 1, and an annular embedding groove 72 corresponding to the sealing ring 73 is provided at the lower end of the basin frame body 2.
[0033] By adopting the above technical solution, when the basin frame body 2 is connected to the U-shaped iron body 1, the sealing ring 73 is first embedded in the annular embedding groove 71. After the basin frame body 2 is fixed, the upper end face of the sealing ring 73 will be stuck in the annular embedding groove 72, thereby improving the connection sealing between the basin frame body 2 and the U-shaped iron body 1.
[0034] Specifically, after the U-shaped iron body 1 is connected and fixed to the frame body 2, the lower end face of the sealing ring 73 is located inside the annular embedding groove 71, and the upper end face of the sealing ring 73 is located inside the annular embedding groove 72.
[0035] By adopting the above technical solution, the structure can facilitate the installation of the sealing ring 73.
[0036] In this embodiment, when the basin frame body 2 is connected to the U-shaped iron body 1, the sealing ring 73 is first embedded in the annular embedding groove 71. After the basin frame body 2 is fixed, the upper end of the sealing ring 73 will be stuck in the annular embedding groove 72, thereby improving the connection sealing between the basin frame body 2 and the U-shaped iron body 1.
[0037] The working principle and usage process of this utility model are as follows: In use, the ear plate 33 is fixed to the inner wall of the basin frame body 2 by the fastening screw 32 to fix the mounting block 37. When connecting and fixing the U-shaped iron body 1 to the basin frame body 2, first press the fixing rod 35. The fixing rod 35 compresses the sliding plate 310 and the spring 39, causing the fixing rod 35 to embed into the mounting block 37. Then, insert the basin frame body 2 into the U-shaped iron body 1. Then rotate the basin frame body 2. When the insertion hole 34 aligns with the fixing hole 31, the spring 39 rebounds, thereby driving the fixing rod 35 to insert into the fixing hole 31, thus achieving the connection of the basin frame body 1 and the mounting block 37. The frame body 2 and the U-shaped iron body 1 are fixed together. When the frame body 2 and the U-shaped iron body 1 are disassembled, the adjusting block 36 inside the sliding adjusting groove 38 is slidable. The adjusting block 36 drives the sliding plate 310 to slide. The sliding plate 310 drives the fixing rod 35 to slide out from the inside of the fixing hole 31, so that the frame body 2 and the U-shaped iron body 1 can be disassembled and separated. When the frame body 2 and the U-shaped iron body 1 are connected, the sealing ring 73 is first embedded in the annular embedding groove 1 71. After the frame body 2 is fixed, the upper end face of the sealing ring 73 will be stuck in the annular embedding groove 2 72, thereby improving the connection sealing between the frame body 2 and the U-shaped iron body 1.
