However, during use, due to the upper housing 1 (such as Figure 1 , Figure 2 As shown in the figure, bulging usually occurs, resulting in a poor user experience. Utility Model Content

[0003] The utility model aims to provide a turbocharger regulator and a turbocharger in view of the deficiencies in the prior art.

[0004] To solve the above technical problems, the utility model adopts the following technical solutions: a turbocharger regulator, comprising an upper shell and a lower shell; wherein the upper shell comprises a top wall and a side wall, and a cavity formed between the inner surface of the top wall and the inner surface of the side wall; the top wall comprises a boss, an annular plane portion and an annular curved surface portion fixedly connected in sequence from the center to the edge; the bottom circumferential edge of the boss is fixedly connected to the first circumferential side edge of the annular plane portion; the second circumferential side edge of the annular plane portion opposite to the first circumferential side edge thereof is fixedly connected to the first circumferential side edge of the annular curved surface portion; the second circumferential side edge of the annular curved surface portion opposite to the first circumferential side edge thereof is fixedly connected to the top circumferential edge of the side wall; the annular curved surface portion is arranged to be concave toward the lower shell; or the annular curved surface portion is arranged to be convex away from the lower shell; the bottom circumferential edge of the side wall is fixedly connected to the top circumferential edge of the lower shell.

[0026] The utility model will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0027] Directional terms such as "inner", "outer", "axial", "circumferential", etc. mentioned in the present invention are only used to refer to the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present invention, but not to limit the present invention.

[0028] like Figures 3 to 8 As shown, the turbocharger regulator of the utility model comprises: an upper shell 1 and a lower shell 2.

[0029] in;

[0030] The upper housing 1 includes a top wall 11 and a side wall 12 , and a cavity 13 formed between an inner surface of the top wall 11 and an inner surface of the side wall 12 .

[0031] The top wall 11 includes a boss 111 , an annular flat portion 112 , and an annular curved portion 113 which are fixedly connected in sequence from the center to the edge.

[0032] The bottom circumferential edge of the boss 111 is fixedly connected to the first circumferential side of the annular plane portion 112. The second circumferential side of the annular plane portion 112, which is opposite to the first circumferential side, is fixedly connected to the first circumferential side of the annular curved surface portion 113. The second circumferential side of the annular curved surface portion 113, which is opposite to the first circumferential side, is fixedly connected to the top circumferential edge of the side wall 12. The annular curved surface portion 113 is arranged to be concave toward the lower shell 2. Alternatively, the annular curved surface portion 113 is arranged to be convex away from the lower shell 2.

[0033] The bottom circumferential edge of the side wall 12 is fixedly connected to the top circumferential edge of the lower shell 2 .

[0034] The boss 111 can be used to fix the regulator nozzle 3, and the gas source enters the cavity 13 through the regulator nozzle 3. In addition, the arrangement of the boss 111 can meet the positioning requirements of the spring 4 and the adjusting rod 5. Under the action of the preload force of the spring 4, the annular plane portion 112 can prevent the pressure plate 6 from deforming.

[0035] Among them, the concave or convex shape formed based on the annular curved surface portion 113 decomposes the force acting on the inner surface of the top wall 11 that causes the top wall 11 to deform axially, thereby reducing the axial force on the top wall 11, thereby improving the pressure resistance of the upper shell 1 and preventing bulging. Compared with the prior art, the deformation of the top wall 11 of the upper shell 1 is small under the same pressure, and the pressure resistance is improved. By changing the direction of the force, the top wall 11 of the upper shell 1 can solve the bulging problem of the upper shell 1 caused by excessive axial pressure in the existing turbocharger regulator.

[0036] In a specific embodiment, Figures 3 to 8 As shown, the annular curved surface portion 113 includes a spherical surface or a conical surface, which has a simple structure, is easy to use, and is easy to shape. When the annular curved surface portion 113 is a spherical surface, compared with when the annular curved surface portion 113 is a conical surface, the top wall 11 of the upper shell 1 has better pressure resistance, a simpler structure, is more convenient to use, and is easier to shape.

[0037] In a specific embodiment, Figures 3 to 5 As shown, when the annular curved surface portion 113 is configured to be concave toward the lower shell 2, the height of the second circumferential side edge of the annular curved surface portion 113 is greater than the height of the top of the boss 111, which can further reduce the axial force on the top wall 11 of the upper shell 1 and further improve the pressure resistance of the upper shell 1.

[0038] In a specific embodiment, Figures 6 to 8 As shown, when the annular curved surface portion 113 is configured to protrude away from the lower shell 2, the height of the first circumferential side edge of the annular curved surface portion 113 is greater than the height of the top of the boss 111, which can further reduce the axial force on the top wall 11 of the upper shell 1 and further improve the pressure resistance of the upper shell 1.

[0039] When the turbocharger regulator of the utility model is in use, since the annular curved surface portion 113 is arranged to be concave or convex, the force acting on the inner surface of the top wall 11 causing the axial deformation of the top wall 11 is decomposed, so that the axial force on the top wall 11 is reduced, thereby improving the pressure resistance of the upper shell 1 and preventing the formation of bulges.

[0040] Based on the above embodiments, Fig. 9 As shown, the present application also proposes a turbocharger, including the turbocharger regulator. Among them, the annular curved surface portion 113 of the top wall 11 of the upper shell 1 of the turbocharger regulator is set to be concave or convex, so that the force acting on the inner surface of the top wall 11 causing the axial deformation of the top wall 11 is decomposed, thereby reducing the axial force on the top wall 11, thereby improving the pressure resistance of the upper shell 1 of the turbocharger regulator, preventing bulging, and improving the performance of the turbocharger.

[0041] The protection scope of the present invention is not limited to the above-mentioned embodiments. Obviously, those skilled in the art can make various modifications and variations to the present invention without departing from the scope and spirit of the present invention. If these modifications and variations fall within the scope of the claims of the present invention and their equivalents, the intent of the present invention also includes these modifications and variations.
