[0025] In order to make the purpose, technical solution and beneficial effects of the utility model more clear, the technical solution of the utility model is further described below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0026] In the embodiment of the present utility model, Figure 1-Figure 4 As shown, the car speaker basin structure includes: a top ring 1, a base 2 and a positioning assembly; the base 2 is coaxially arranged with the top ring 1, the base 2 has an upper end face and an outer end face, and its outer end face is connected to the top ring 1 through a plurality of support arms 3; the positioning assembly includes an annular groove 201 formed on the upper end face of the base 2, and a positioning pressure ring 4 placed in the annular groove 201, the positioning pressure ring 4 is detachably arranged on the base 2, and a plurality of first positioning blocks 5 are arranged along its circumference, the first positioning blocks 5 penetrate the base 2 and are detachably connected to the outer end face of the base 2; wherein, an installation cavity is formed between the positioning pressure ring 4 and the annular groove 201 for installing a spring.

[0027] Specifically, in the embodiment of the utility model, the top ring 1, the support arm 3 and the base 2 are connected in sequence to form the main frame of the basin frame, and the main frame is nearly trumpet-shaped to install corresponding components; for example, multiple step surfaces are set at the top ring 1 for installing drum paper. Since the base 2 needs to install magnetic conductive components, etc., a groove is set on the surface of the base 2, and a through hole is opened at the bottom of the groove. The top of the above groove is defined as the upper end surface of the base 2, and the peripheral surface of the base 2 is its outer end surface, and the support arm 3 is fixed at the outer end surface to increase the accommodating area of ​​the above groove and reduce obstruction.

[0028] In the embodiment of the utility model, an annular groove 201 is provided on the upper end surface of the base 2, and the annular groove 201 is arranged around the above-mentioned groove for installing the wave damper. Of course, in order to avoid installation wrinkles of the wave damper at the annular groove 201, as shown in FIG. Figure 2 , Figure 3 As shown, the side of the annular groove 201 close to the groove is open to communicate with the groove; or the connection between the two can be rounded. On the other hand, in order to fix the spring to the annular groove 201, this embodiment is provided with a positioning pressure ring 4, which is placed above the annular groove 201 and is arranged in a conformal manner with the annular groove 201, so that the positioning pressure ring 4 can press the spring to the annular groove 201.

[0029] Specifically, since the spring and the positioning pressure ring 4 need to be installed in sequence, the positioning pressure ring 4 is detachably arranged at the base 2; when the spring is installed in place, the positioning pressure ring 4 is placed on the upper surface of the spring; on the other hand, in order to fix the positioning pressure ring 4 at the base 2 so as to limit the spring in the installation cavity formed between the positioning pressure ring 4 and the annular sink 201, a first positioning block 5 (such as Figure 4 As shown, this embodiment takes two first positioning blocks 5 arranged opposite to each other as an example. After the positioning pressure ring 4 is in place, the first positioning block 5 can penetrate the base 2 and extend out of the outer end surface of the base 2, and at the same time, it can be detachably connected to the outer end surface of the base 2, so that the positioning pressure ring 4 and the base 2 and the elastic wave can be relatively fixed by fixing the first positioning block 5 to the base 2. At the same time, since the first positioning block 5 is a through-type, the stability of the positioning pressure ring 4 can be improved, and the positioning pressure ring 4 can be limited in the axial and radial directions to prevent the elastic piece from shifting or falling off. Of course, this basin frame is a plastic product, so the first positioning block 5 can penetrate the base 2 under the elasticity of the plastic itself.

[0030] In this embodiment, the spring wave can be initially positioned at the base 2 by setting the annular groove 201, and the spring wave can be fixed therein by the cooperation between the positioning pressure ring 4 and the annular groove 201; and the detachable positioning pressure ring 4 is easy to install and disassemble, avoiding irreversible installation caused by bonding.

[0031] In one embodiment, the base 2 is provided with a plurality of avoidance openings for avoiding each of the first positioning blocks 5. The avoidance openings allow the corresponding first positioning blocks 5 to pass through and limit the first positioning blocks 5, thereby limiting the axial or radial movement of the positioning pressing ring 4.

[0032] like Figure 2 As shown, in one embodiment, the outer end surface of the base 2 is provided with a plurality of second positioning blocks 6 protruding outward, and the plurality of first positioning blocks 5 and the plurality of second positioning blocks 6 are arranged one by one, and any group of the first positioning blocks 5 and the second positioning blocks 6 are detachably connected. Specifically, in order to facilitate the detachable installation of the first mounting block on the outer surface of the base 2, the present embodiment fixes the second positioning blocks 6 on the outer surface of the base 2, and the number of the second positioning blocks 6 should be equal to the number of the first positioning blocks 5, and the positions are the same; at the same time, the second positioning blocks 6 are extended in the direction in which the first positioning blocks 5 extend, that is, the second positioning blocks 6 protrude from the outer end surface of the base 2, and are extended in the direction away from the outer end surface thereof; preferably, the first positioning blocks 5 and the second positioning blocks 6 are both provided with threaded holes for screwing in screws.

[0033] like Figure 4As shown, in one embodiment, the upper surface and / or the lower surface of the positioning pressure ring 4 are provided with a plurality of deformation openings 401, and the deformation openings 401 are located between two adjacent first positioning blocks 5. Specifically, in order to allow the first positioning block 5 to pass through the base 2, this embodiment takes the arrangement of two deformation openings 401 on the upper surface of the positioning pressure ring 4 as an example, and the deformation openings 401 weaken the upper surface of the positioning pressure ring 4 and allow the positioning pressure ring 4 to bend to a certain extent, and the bending point is located at the deformation openings 401, so as to facilitate the insertion of the first positioning block 5 into the avoidance opening. In other embodiments, the positioning pressure ring 4 can also be divided into left and right parts through the deformation openings 401, and the connection between the two parts is connected by plug-in, which can also facilitate the installation of the first positioning block 5 in place.

[0034] like Figure 2 As shown, in one embodiment, a glue sinking groove 202 is provided at the bottom of the annular sinking groove 201. Specifically, in order to facilitate the preliminary positioning of the elastic wave at the annular sinking groove 201, a small amount of glue can be dripped at intervals at the annular sinking groove 201 to fix the elastic wave; and in order to avoid glue overflow when pressing down the elastic wave, this embodiment sets a glue sinking groove 202 at the bottom of the annular sinking groove 201. The glue sinking groove 202 can be multiple and spaced, or it can be an annular through groove, which is used to collect excess glue to avoid glue overflow from the elastic wave; preferably, the cross-section of the glue sinking groove 202 can be V-shaped or U-shaped. At the same time, the double fixing method can also make the elastic wave fixed at the base 2 for a long time.

[0035] like Figure 3 As shown, in one embodiment, the top ring 1 protrudes outward to form a plurality of mounting protrusions 7, each of which is provided with a mounting hole, and two adjacent mounting protrusions 7 are connected by a reinforcing rib 8. Specifically, in order to fix the basin rack to the sheet metal of the automobile, the present embodiment provides four mounting protrusions 7 on the circumference of the top ring 1, and two adjacent mounting protrusions 7 are connected by a reinforcing rib 8, so as to strengthen the connection strength between the two adjacent mounting protrusions 7 and the mounting protrusion 7 and the top ring 1; and a mounting hole is provided at each mounting protrusion 7, so as to realize the rapid installation or removal of the basin rack.

[0036] like Figure 1-Figure 3 As shown, in one embodiment, the support arm 3 is divided by a notch to form a first support portion and a second support portion, and the first support portion and / or the second support portion are in an arc-shaped structure. Specifically, in order to improve the overall structural strength of the basin stand, the present embodiment divides the support arm 3 into a first support portion and a second support portion, the middle portions of the two support portions are separated by a notch, and the two ends of the two support portions converge to the top ring 1 and the base 2, respectively, and both are in an arc-shaped structure, so as to improve the connection strength between the top ring 1 and the base 2 and prevent the basin stand from deformation.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
