Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] This utility model provides, for example Figures 1-6 The structure of a car Bluetooth speaker box shown includes a bridge hole lower panel 1 and a Bluetooth speaker box 2 fixedly installed on one side of the bridge hole lower panel 1. The bridge hole lower panel 1 has a placement opening that communicates with the interior of the Bluetooth speaker box 2. A Bluetooth speaker 4 is placed inside the Bluetooth speaker box 2, and the top of the Bluetooth speaker 4 is inside the placement opening. A speaker trim 5 is also installed on the placement opening.

[0028] The Bluetooth speaker box 2 includes a first shell 21 and a second shell 22 that can be spliced ​​together, and a snap-fit ​​assembly that snaps the first shell 21 and the second shell 22 together.

[0029] Specifically, the latching assembly includes a first latch 7, a third latch 9, a second latch 8, and a fourth latch 10 respectively disposed at both ends of the first housing 21 and the second housing 22, with the first latch 7 and the third latch 9 being staggered with the second latch 8 and the fourth latch 10.

[0030] As described above, in use, the first shell 21 and the second shell 22 are first spliced ​​together, and the first shell 21 and the second shell 22 are snapped together by the first buckle 7, the third buckle 9, the second buckle 8 and the fourth buckle 10, so that the first shell 21 and the second shell 22 are assembled together to form the Bluetooth speaker box 2. Then, the Bluetooth speaker box 2 is fixedly installed to the lower panel 1 of the bridge hole by welding. Then, the Bluetooth speaker 4 is put into the Bluetooth speaker box 2 through the placement port, thereby realizing vehicle fixation and facilitating the vehicle use of the Bluetooth speaker 4.

[0031] Secondly, the Bluetooth speaker box 2 is composed of a first shell 21 and a second shell 22, and the opening size and bottom size are the same, ensuring that the gaps around the Bluetooth speaker 4 and the Bluetooth speaker box 2 are uniform. This effectively solves the problem of large opening size and small bottom size of box-type injection molded parts due to demolding. At the same time, the uniform gaps can prevent the Bluetooth speaker 4 from shaking inside the Bluetooth speaker box 2, thus achieving stable placement of the Bluetooth speaker 4.

[0032] Furthermore, to increase storage space and facilitate the storage of personal belongings, such as... Figures 1-3 As shown, a storage box 3 is also installed at one end of the lower panel 1 of the bridge opening, and a slot communicating with the storage box 3 is opened on the lower panel 1 of the bridge opening.

[0033] Meanwhile, in this embodiment, such as Figures 4-6 As shown, the inner wall of the first housing 21 is injection molded with a first soft rubber 211 and a second soft rubber 212 in two colors, and the inner wall of the second housing 22 is injection molded with a fourth soft rubber 222 and two third soft rubbers 221 in two colors.

[0034] When the Bluetooth speaker 4 is placed into the Bluetooth speaker box 2, the first soft rubber 211, the second soft rubber 212, the fourth soft rubber 222 and the two third soft rubbers 221 are interference-fitted with the Bluetooth speaker 4, tightly holding the Bluetooth speaker 4, thereby increasing the stability of the Bluetooth speaker 4 when placed and avoiding NVH and safety issues.

[0035] Additionally, in this embodiment, as Figure 2 As shown, iron blocks 6 are embedded in the bottom of both the first shell 21 and the second shell 22.

[0036] When the Bluetooth speaker 4 is placed into the Bluetooth speaker box 2, the iron block 6 can be attracted to the magnet inside the Bluetooth speaker 4 to magnetically fix the Bluetooth speaker 4, thereby further increasing the stability of the Bluetooth speaker 4 when it is placed and preventing the Bluetooth speaker 4 from flying out during vehicle operation.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
