In addition, the existing bracket is usually fixed to the outside of the valve body by bolts and other components. Although the bracket can be fixed, the bolts are prone to loosening during vibration, thereby affecting the transmission efficiency of the linkage. Utility Model Content

DETAILED DESCRIPTION

[0021] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0022] See also Figure 1-5 The utility model provides an embodiment: an automobile exhaust pipe valve, comprising a valve body 1, a bracket 5 integrally formed with the valve body 1, and an actuator assembly 2 installed below the bracket 5; the actuator assembly 2 comprises a driving member 6 and a driving shaft 7 arranged on the driving member 6; wherein the driving shaft 7 is connected to a valve disc shaft 8 on the valve body 1 through a linkage member 3; the actuator assembly 2 also comprises a heat insulating member 9 covering the outside of the driving member 6, and an airflow channel 4 for facilitating airflow is formed between the facing surfaces of the heat insulating member 9 and the bracket 5.

[0023] To summarize, since the bracket 5 and the valve body 1 are an integral structure, for example, the bracket is welded to the valve body by welding or they are molded together, the problem of looseness between the bracket 5 and the valve body 1 due to vibration during use can be effectively solved; at the same time, the heat insulation member 9 is used to cover the outside of the driving member, and the air flow is guided by the air flow channel 4, thereby reducing the heat radiation of the valve body 1 to the driving member 6, which may easily cause the driving member 6 to be scorched; in addition, the heat insulation member 9 is located below the bracket 5 and cooperates with the heat insulation member 9, so while blocking the heat radiation, the space on the side of the valve body 1 can be fully utilized to make the overall structure of the valve body 1 more compact.

[0024] Furthermore, since an air inlet 10 is provided on one side of the thermal insulation member 9 and an exhaust port 11 is provided on the other side of the thermal insulation member 9, the heat source entering the thermal insulation member 9 can be quickly discharged under the action of the air inlet 10 and the exhaust port 11, thereby further improving the thermal insulation capacity of the equipment.

[0025] In order to prevent the heat source from being directly transferred to the driving member 6 through the bracket 5, a connecting plate 12 is further provided on the upper end surface of the thermal insulation member 9, and the connecting plate 12 is fitted to the lower surface of the bracket 5. Therefore, the connecting plate 12 can be used to cut off the direct connection between the bracket 5 and the driving member 6, thereby reducing the influence of heat on the driving member 6.

[0026] At the same time, the fastener is passed through the bracket 5 and the connecting plate 12 and connected to the driving member 6, so that the assembly of the driving member 6 is simple and convenient. Among them, the heat insulating member 9 is processed by sheet metal technology, so that the heat insulating member 9 has the advantage of being easy to process.

[0027] On the basis of the above solution, since a limiting column 13 is further provided between the bracket 5 and the valve flap shaft 8, the limiting column is used to limit the movement stroke of the linkage member 3 to prevent the linkage member 3 from moving excessively, thereby preventing the valve flap from being loosely closed or too tightly closed. In particular, the limiting column 13 is provided between the bracket 5 and the valve flap shaft 8, thereby further optimizing the structure of the valve body 1 and making it more compact.

[0028] Specifically, the linkage member 3 includes a linkage rod 30; one end of the linkage rod 30 is connected to the drive shaft 7 via a provided driving arm 31, and the other end of the linkage rod 30 is connected to the valve flap shaft 8 via a provided operating arm 33. Therefore, when the driving member 6 prompts the linkage member 3 to move to the left, the operating arm 33 abuts against the limit column 13 to prevent the linkage member 3 from continuing to move, so as to avoid the problem of excessive closing or loose closing of the valve flap.

[0029] In addition, since the driving arm 31 passes through the linkage rod 30 and is connected to the nut 32, and the driving arm 31 is fixedly mounted on the driving arm 31, the integrated driving arm 31 can improve the structural strength of the driving arm 31.

[0030] Furthermore, since the driving arm 31 and the operating arm 33 are both provided with a polygonal hole 35 at one end away from the linkage rod 30, for example, the polygonal hole 35 on the driving arm 31 is a waist-shaped hole, and the polygonal hole 35 on the operating arm 33 is a rectangular hole; since the polygonal hole is connected to the corresponding shaft, the problem of the valve flap shaft 8 or the driving shaft 7 being easily broken during use due to the two ends of the linkage part 3 being welded to the driving shaft 7 and the valve flap shaft 8 is solved; at the same time, the above structure also has the advantages of simple structure, easy manufacturing and installation, and easy assembly.

[0031] The above is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
