[0028] See also Figures 1 to 4 The present invention provides a speaker 100 bracket combination structure arranged in a car water trough 10, comprising a main bracket 1 and a sub-bracket 2; the main bracket 1 is provided with a first main mounting surface 11 connected to the water trough 10 and a second main mounting surface 12 connected to the speaker 100, and the second main mounting surface 12 is provided with a positioning hole 121 of the main bracket 1 and a first mounting hole 122 and a second mounting hole 123 of the speaker 100; the sub-bracket 2 is provided with a first sub-mounting surface 21 connected to the water trough 10 and a second sub-mounting surface 22 connected to the speaker 100, and the second sub-mounting surface 22 is provided with a third mounting hole 221 of the speaker 100; wherein the first mounting hole 122 and the second mounting hole 123 are respectively provided at two ends of the second main mounting surface 12, and cooperate with the third mounting hole 221 to form three points for connecting the speaker 100.

[0029] In this embodiment, the main bracket 1 is connected and fixed to the water trough 10 through its own first main mounting surface 11 and second main mounting surface 12, and provides a fulcrum for the installation and fixation of the speaker 100. The sub-bracket 2 is fixed to the water trough 10 and provides a fulcrum for the installation and fixation of the speaker 100 through its first sub-mounting surface 21 and second sub-mounting surface 22. The speaker 100 forms a three-point connection arrangement according to the first mounting hole 122, the second mounting hole 123 and the third mounting hole 221 on the main bracket 1 and the sub-bracket 2 to avoid occupying a large space. By combining the main bracket 1 and the sub-bracket 2, the space is fully and effectively utilized to ensure that the boundary between the main bracket 1 and the sub-bracket 2 is small enough, thereby achieving the requirement of lightweight.

[0030] It should be noted that in the original structure of the water trough 10, the space occupied by mechanisms such as the wiper, wiper arm and wiper motor is arranged on the left side, and the space occupied by the air-conditioning outlet is arranged on the middle right. Therefore, only the space for installing the speaker 100 is left on the rightmost side of the water trough 10.

[0031] See also Figure 2 In one embodiment, the first main mounting surface 11 includes a side mounting surface 111 and a bottom mounting surface 112. The side mounting surface 111 is connected to the side wall of the water trough 10 and is adjacent to one side of the second main mounting surface 12; the bottom mounting surface 112 is connected to the bottom wall of the water trough 10 and is adjacent to the other side of the second main mounting surface 12.

[0032] Furthermore, a groove 1110 is provided on the side of the side mounting surface 111 away from the second main mounting surface 12, and a serrated cutting edge is formed on the side mounting surface 111; a convex structure is provided on the side of the bottom mounting surface 112 away from the second main mounting surface 12, and a serrated cutting edge is formed on the bottom mounting surface 112.

[0033] The side mounting surface 111 and the bottom mounting surface 112 of the main bracket 1 are welded to the side wall and the bottom wall of the water trough 10 respectively, so that the main bracket 1 can be fixed on the water trough 10 at two different angles and cooperate with the shape structure of the main bracket 1 itself to ensure the stability of the main bracket 1. At the same time, by opening a serrated cutting edge on the outer side of the side mounting surface 111 and the bottom mounting surface 112 of the main bracket 1, the weight of the parts is further reduced to meet the lightweight requirements.

[0034] See also Figure 2 In one embodiment, the bottom mounting surface 112 is provided with at least two, which are respectively located on one side of the first mounting hole 122 and the second mounting hole 123 on the second main mounting surface 12. A flange 120 is provided at the portion where the second main mounting surface 12 connects to the bottom mounting surface 112, so as to form a height difference between the second main mounting surface 12 and the bottom mounting surface 112, and the main bracket 1 forms a "bridge-type" structure through the flange 120 of the second main mounting surface 12.

[0035] On the one hand, the main bracket 1 is connected to the water trough 10 through the bottom mounting surface 112 and the side mounting surface 111 respectively, thereby enhancing the firmness of its own structure. On the other hand, by providing at least two bottom mounting surfaces 112, and arranging the two bottom mounting surfaces 112 on one side of the first mounting hole 122 and the second mounting hole 123 on the main bracket 1, the weight of the installed speaker 100 is directly transferred to the bottom mounting surface 112 through the two mounting holes, and is directly loaded by the water trough 10 mechanism, thereby ensuring the effective function of the force transmission path of the main bracket 1. At the same time, a flange 120 is provided on the second main mounting surface 12 to connect the bottom mounting surface 112. On the one hand, a "bridge-type" structure is formed between the bottom mounting surface 112, so that the bottom mounting surface 112 is respectively placed at both ends of the "bridge-type" structure to respectively load the weight of the installed speaker 100. On the other hand, the height difference formed by the flange 120 is used to adapt to the height parameters required for installing the speaker 100 in the water trough 10 structure.

[0036] Furthermore, a reinforcing rib 1201 is provided on the flange 120 of the second main mounting surface 12, and the two ends of the reinforcing rib 1201 are respectively facing the bottom mounting surface 112 and the second main mounting surface 12. The reinforcing rib 1201 is provided on the flange 120 connecting the bottom mounting surface 112 and the second main mounting surface 12, thereby increasing the support of the bracket assembly structure in the Z direction (i.e., in the gravity direction of the bracket assembly structure) and reducing the rebound of the parts, thereby ensuring the stiffness requirement (≥600N / mm) of the woofer 100.

[0037] See also Figure 2 In one embodiment, the first sub-mounting surface 21 is provided with at least two bottom walls connected to the water trough 10 and respectively located on different sides of the second sub-mounting surface 22. A flange 220 is provided at the portion where the second sub-mounting surface 22 is connected to the first sub-mounting surface 21 to form a height difference between the second sub-mounting surface 22 and the first sub-mounting surface 21, so as to form a "bridge-type" structure of the sub-bracket 2 through the flange 220 of the second sub-mounting surface 22. Similarly, a flange 220 and a "bridge-type" structure are also provided on the sub-bracket 2, and their functions are the same as those of the main bracket 1, and are not described in detail here. The "bridge-type" structure with flanges 120 / 220 on the main bracket 1 and the sub-bracket 2 ensures the dynamic stiffness requirements (≥600N / mm) of the woofer 100.

[0038] See also Figure 2 In one embodiment, the positioning hole 121 includes a main positioning hole 1211 close to the first mounting hole 122 and a secondary positioning hole 1212 close to the second mounting hole 123. The main positioning hole 1211 and the secondary positioning hole 1212 are configured as the limiting hole 101 for mounting the speaker 100.

[0039] The main positioning hole 1211 and the auxiliary positioning hole 1212 opened on the second main mounting surface 12 can provide positioning for the main bracket 1 to be installed on the water trough 10, and can also be used as the limiting hole 101 for installing the speaker 100. The self-positioning pin on the speaker 100 cooperates with the main positioning hole 1211 and / or the auxiliary positioning hole 1212, so as to facilitate the stability and convenience of its installation and disassembly.

[0040] In the process of installing the speaker 100 on the water trough 10 structure, the main bracket 1 and the auxiliary bracket 2 are first positioned in the corresponding positions on the water trough 10 in sequence by using a clamp to cooperate with the main positioning hole 1211 and the auxiliary positioning hole 1212 on the main bracket 1, and then fixed to the water trough 10 by welding. The speaker 100 is installed by using the positioning hole 121 of the main bracket 1 as the limit hole 101 of the speaker 100 through its self-positioning pin, and then the position is fine-tuned and the bolts are tightened to connect to the three mounting holes of the main bracket 1 and the auxiliary bracket 2.

[0041] In summary, the present invention provides a speaker 100 bracket combination structure arranged in a car water trough 10, which is combined by a main bracket 1 and a sub-bracket 2 to fully utilize the space of the water trough 10, meet the requirements of the speaker 100 being arranged at three points, and ensure that the boundaries of the main and sub-brackets 2 are made small enough to achieve the requirement of lightweight; by arranging a "bridge-type" structure with a flange 120 / 220 on the main bracket 1 and the sub-bracket 2, the structural strength of the main bracket 1 and the sub-bracket 2 is increased, thereby ensuring the dynamic stiffness requirements of the installation of the speaker 100.

[0042] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
