[0032] Referring to Figures 1 to 6 , the present utility model provides an automobile loudspeaker that is convenient for disassembly and assembly, including: a fixed bracket 1, the fixed bracket 1 is cylindrical, and a loudspeaker 2 is disposed through the inner wall of the fixed bracket 1; a disassembly and assembly component 3 is arranged outside the loudspeaker 2, the disassembly and assembly component 3 includes a locking pin 31 in an L shape, an insertion hole 101 for the locking pin 31 to slide through is arranged on the side wall of the fixed bracket 1, a guiding inclined surface portion 310 is arranged at the first end of the locking pin 31, and the first end of the locking pin 31 passes through the insertion hole 101 and is clamped to the loudspeaker 2, an elastic member 32 is connected to the side of the second end of the locking pin 31 close to the loudspeaker 2, and the end of the elastic member 32 away from the locking pin 31 is connected to the fixed bracket 1. Wherein, when the locking pin 31 is driven to move in a direction away from the loudspeaker 2 to a preset position, the guiding inclined surface portion 310 completely retracts into the insertion hole 101.

[0033] In the above embodiment, the fixing bracket 1 is cylindrical, with a through middle part, and a part of the platform extends outward from the top. The fixing bracket 1 is used for fixedly installing at a suitable position on the car door or the carriage. When the speaker 2 needs to be disassembled and assembled, the fixing bracket 1 does not need to be disassembled, and the speaker 2 in the fixing bracket 1 can be directly disassembled through the disassembly and assembly component 3. The speaker 2 is installed through the inner wall of the fixing bracket 1. The disassembly and assembly component 3 includes a L-shaped locking pin 31. The long end of the L-shape is parallel to the side wall of the fixing bracket 1. A guiding inclined surface portion 310 is provided on the end surface of the short end of the L-shape. It passes through the insertion hole 101 and is clamped to the speaker 2. An elastic member 32 is provided on the side of the long end of the locking pin 31 close to the speaker 2. This elastic member 32 is preferably a tension spring, which automatically rebounds after being stretched.

[0034] By using the L-shaped locking pin 31 with the guiding inclined surface portion 310, the function of quickly disassembling and assembling the speaker 2 is realized. When the speaker 2 is inserted into the fixing bracket 1 for installation, the locking pin 31 with the guiding inclined surface portion 310 can be automatically slid into the insertion hole 101 under the extrusion of the speaker 2. The cylinder of the fixing bracket 1 allows the speaker 2 to pass through completely. After the speaker 2 is installed in place, the locking pin 31 is reset under the action of the elastic member 32 and reinserted and locked to the speaker 2 to fix the speaker 2. The speaker 2 cannot be pushed out of the fixing bracket 1. When the speaker 2 needs to be disassembled, only the locking pin 31 needs to be pulled out in the direction away from the speaker 2 to further take out the speaker 2, realizing the stable installation and convenient disassembly and assembly of the speaker 2.

[0035] Reference Figures 3 to 5 Referring to, in one embodiment, the disassembly and assembly component 3 further includes a toggle lever 33.

The toggle lever 33 is fixedly connected to the locking pin 31, and the upper end penetrates the top of the fixing bracket 1. A waist-shaped hole 102 for the toggle lever 33 to slide is provided at the top of the fixing bracket 1. The waist-shaped hole 102 provides a certain amount of movement space for the toggle lever 33 and at the same time limits the sliding direction of the toggle lever 33. By toggling the toggle lever 33, the unlocking and locking operations of the locking pin 31 can be easily realized. It not only simplifies the operation steps but also improves the work efficiency, making the disassembly and assembly process smoother and more convenient.

[0037] Reference Figures 2 to 5In one embodiment, the disassembly and assembly component 3 also includes an adjusting ring 34, which is arranged at the top of the fixing bracket 1. The adjusting ring 34 is provided with an arc-shaped hole 341, and the toggle rod 33 is passed through the arc-shaped hole 341. The adjusting ring 34 is rotated so that the arc-shaped hole 341 drives the toggle rod 33 to slide in the waist-shaped hole 102, so that the locking pin 31 slides in the insertion hole 101.

[0038] In the above embodiment, simply rotating the adjustment ring 34 guides the toggle rod 33 through the arcuate hole 341 to slide within the waist-shaped hole 102, thereby precisely moving the locking pin 31 within the insertion hole 101. This eliminates the need for complex tools or tedious steps, significantly improving the convenience and efficiency of assembly and disassembly. Furthermore, the tight fit between the adjustment ring 34 and the fixed bracket 1 ensures the stability and reliability of the assembly 3 during long-term use.

[0046] The combination of the speaker 2 and the fixing bracket 1 is not limited to the abutment of the limiting ring 4. It can further ensure the stability of the speaker 2. An elastic buffer pad is added around the inner edge of the limiting ring 4. The buffer pad is made of a soft and durable material, such as silicone or rubber, which can provide moderate elastic compression during the installation of the speaker 2, effectively reducing the noise transmission caused by vibration or external impact, and protecting the speaker 2 from potential damage. In addition, the buffer pad can also help achieve a seamless connection between the speaker 2 and the fixing bracket 1, improving the overall assembly accuracy.

[0047] In one embodiment, a plurality of guiding protrusions 5 are provided on the inner wall of the fixing bracket 1. The bottom end of the guiding protrusion 5 abuts against the top end of the limiting ring 4, and a guiding groove 6 matching the guiding protrusion 5 is provided on the side wall of the speaker 2.

[0048] In the above embodiment, the guiding protrusions 5 on the inner wall of the fixing bracket 1 can automatically align the position of the speaker 2 during installation. After ensuring the docking of the guiding protrusion 5 and the guiding groove 6, the locking pin 31 of the disassembly and assembly component 3 can be inserted into the prefabricated locking slot hole of the speaker 2 for corresponding matching and clamping fixation, thereby ensuring the accuracy of the connection between the speaker 2 and the disassembly and assembly component 3 in the fixing bracket 1.

[0049] In addition, the guiding protrusions 5 can also ensure that the speaker 2 is evenly stressed during the installation process, avoiding the risk of damage caused by excessive single-point stress. With the close cooperation of the limiting ring 4 and the guiding protrusions 5, the connection tightness between the speaker 2 and the fixing bracket 1 is further improved.
