[0001] The utility model relates to the field of automotive parts, and particularly to an automotive foamed rubber block. Background Art

[0002] In the process of automobile production and manufacturing, foamed rubber blocks are often arranged between the sheet metal parts of the automobile as sound insulation components. The foamed rubber block is a foamed object made of polyurethane or other materials, and it has good sound insulation performance.

[0003] The existing automotive foamed rubber block is composed of a binding frame and foamed rubber material. Corresponding slots are opened in the binding frame for placing the foamed rubber material. According to the shape of the automotive sheet metal parts, the shapes of the binding frame and the slots are mostly irregular. The existing foamed rubber material and the slots of the binding frame are combined by adhesion. When the foamed rubber material ages and needs to be replaced, when removing the glue in the binding frame, the glue at the adhesion part is not easy to remove and is easy to have residues. In this way, when filling the subsequent glue material, it is not easy to combine with the binding frame. Therefore, an automotive foamed rubber block is proposed. Summary of the Utility Model

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] The present invention provides a Figures 1-4 shown automotive foaming rubber block, including a binding frame 1. Multiple foaming rubber materials 2 are arranged in the middle of the binding frame 1. Multiple liquid passing holes 101 are opened in the middle of the binding frame 1. Multiple fixing holes 102 are circumferentially opened on the side of the binding frame 1. Through the designer of the fixing holes 102, the binding frame 1 can be fixed inside the automotive sheet metal parts, so that it is stably arranged inside the automotive sheet metal parts.

[0024] Specifically, multiple placing openings 103 are opened in the middle of the binding frame 1 and around the liquid passing holes 101, and the foaming rubber materials 2 are arranged in the placing openings 103.

[0025] It should be noted that the foaming rubber materials 2 can be polyurethane foaming rubber and rubber foaming rubber. Their shapes fit the placing openings 103, and the specific shapes are determined according to the internal structure of the sheet metal parts in the area where the vehicle needs to be installed. After the foaming rubber materials 2 are prepared into rubber blocks, they can effectively block external noises, thereby improving the quietness inside the vehicle. At the same time, they also have moisture-proof performance, reduce the moisture inside the vehicle, and prevent the growth of mold.

[0026] It also includes:

[0027] A clamping structure. Multiple groups of clamping structures are respectively arranged around the side of the connection between the binding frame 1 and the foaming rubber material 2. The clamping structure is used for pressing and fixing the foaming rubber material 2 in the binding frame 1;

[0028] Specifically, multiple connecting grooves 104 are opened on the inner walls at both ends of the multiple placing openings 103. The connecting grooves 104 are used to connect the clamping structure.

[0029] Furthermore, the clamping structure includes a clamping piece 4. One end of the clamping piece 4 is inserted and connected into the connecting groove 104, and the other end of the clamping piece 4 is suspended at the placing opening 103 to limit the foaming rubber material 2.

[0030] It should be noted that in the setting of this solution, the connecting groove 104 is set to be oval, and one end of the clamping piece 4 connected to the connecting groove 104 fits the shape of the connecting groove 104, while the end of the clamping piece 4 away from the connecting groove 104 is set to be semi-circular. Such a structural setting enables the semi-circular structure to cover the placing opening 103. Under this covering and blocking, the foaming rubber material 2 can be clamped by the oppositely arranged clamping pieces 4, thereby completing the restraint and limitation of the foaming rubber material 2 in the placing opening 103.

[0031] Furthermore, a plurality of threaded grooves 105 are formed in the inner wall of the connecting groove 104. A fixing screw 401 is inserted through the side of the clamping piece 4 away from the restraint frame 1, and the threaded end of the fixing screw 401 is threadedly inserted into the inner wall of the threaded groove 105.

[0032] It should be noted that through the threaded fit between the fixing screw 401 and the threaded groove 105, the fixing screw 401 squeezes the clamping piece 4 to make it close to the restraint frame 1, so that the clamping piece 4 can closely adhere to the foaming rubber material 2 for restraint and limitation. At the same time, due to the design of the fixing screw 401, the clamping piece 4 can also be disassembled flexibly, which is convenient for replacing the foaming rubber material 2.

[0033] A plurality of baffles 3 are arranged at the port of the placing opening 103 and on the side close to the liquid passing hole 101. The plurality of baffles 3 are used to cooperate with the clamping piece 4 to block and limit the foaming rubber material 2 in the placing opening 103.

[0034] It should be noted that through the cooperation of the baffles 3, the foaming rubber material 2 can find the placing position in the placing opening 103, and at the same time, it also cooperates with the clamping piece 4 to squeeze the foaming rubber material 2.

[0035] An elastic connecting piece is arranged on the outer wall of the restraint frame 1 and is used for connecting the restraint frame 1 in the automotive sheet metal part.

[0036] Specifically, the elastic connecting piece includes a first elastic clamping block 5 and a second elastic clamping block 6. The first elastic clamping block 5 and the second elastic clamping block 6 are symmetrically arranged along the center on the outer wall of the restraint frame 1, and the ends of the first elastic clamping block 5 and the second elastic clamping block 6 away from the restraint frame 1 are provided with clamping mouths.

[0037] It should be noted that both the first elastic clamping block 5 and the second elastic clamping block 6 are made of polyurethane material. Since the polyurethane material has good elasticity, wear resistance and chemical resistance, the first elastic clamping block 5 and the second elastic clamping block 6 prepared therefrom have good deformation recovery ability. At the same time, blocking branches are provided on the opposite sides of the first elastic clamping block 5 and the second elastic clamping block 6. Through such a structural setting, the structure clamped between the opposite sides of the first elastic clamping block 5 and the second elastic clamping block 6 is blocked and restricted, so that the present foaming rubber block can be arranged at the automotive sheet metal part.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
