[0035] Although the terms first, second, etc. may be used herein to describe multiple elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms may only be used to distinguish one element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates otherwise, terms such as "first", "second" and other numerical terms do not imply a sequence or order when used herein. In addition, in the description of this application, unless otherwise clearly specified and limited, the terms "set" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium.

[0037] The following combination Figures 1 to 11 An embodiment of a vehicle stand is described in detail.

[0038] Reference Figures 1 to 5 The present application provides a vehicle test stand 100, which includes a frame 110 and a head portion 120. The head portion 120 is arranged at the front of the frame 110, and the head portion 120 includes a head movable frame 121 and a head fixed frame 122 arranged on the left and right sides thereof. The front sides of the head movable frame 121 and the head fixed frame 122 constitute a head component mounting surface S1; the head movable frame 121 can move forward and backward and can be locked between a first position and a second position. When the head movable frame 121 moves forward to the first position, the curvature of the head component mounting surface S1 is K1. When the head movable frame 121 moves backward to the second position, the curvature of the head component mounting surface S1 is K2, wherein K2<K1.

[0039] In this embodiment, the front part 120 is set to move forward and backward through the front movable frame 121, thereby forming a front component mounting surface S1 with adjustable curvature with the front fixed frames 122 on its left and right sides. The front movable frame 121 can be arbitrarily locked between the first position and the second position in the front and rear directions, so that the front part 120 can flexibly adapt to any front component with a curvature between K2 and K1, improving the problems of rigid test stand structure and poor versatility, saving the manufacturing cost of multiple test stands, shortening the testing cycle of front components with different curvatures, and bringing great convenience to the research and development of actual vehicles and their components.

[0040] It should be noted that the front component mounting surface S1 is a virtual curved surface provided directly by the front movable frame 121 and the front fixed frame 122 or indirectly through the front load bracket B2 thereon.
