As shown in fig. 1, the adjustable vehicle body 100 includes a mounting and positioning floor 10 and a vehicle body frame positioned and mounted on the floor 10. The vehicle body frame can be composed of components such as aluminum round tubes, aluminum square tubes, aluminum plates, aluminum plate welding parts and connecting parts. The vehicle body frame includes front uprights 11a and 11b standing on the floor panel 10, rear uprights 21a and 21b, a front upper connecting rod 12 connecting upper portions (particularly, tops) of the front uprights 11a and 11b, a rear upper connecting rod 22 connecting upper portions (particularly, tops) of the rear uprights 21a and 21b, a side upper connecting rod 23a connecting upper portions (particularly, tops) of the front upright 11a and the rear upright 21a, and a side upper connecting rod 23b connecting upper portions (particularly, tops) of the front upright 11b and the rear upright 21 b. The distance between the front upper connecting rod 12 and the rear upper connecting rod 22 may determine an upper length (particularly, a roof length) of the vehicle body frame, and the distance between the side upper connecting rods 23a and 23b may determine an upper width (particularly, a roof width) of the vehicle body frame. In some embodiments, the bottom plate may be an aluminum plate, and the uprights and connecting rods may be aluminum round tubes or aluminum square tubes, for example.

The upright stanchion and the upper connecting rod and the crossed upper connecting rods are respectively connected, namely, the upright stanchion and the upper connecting rods and the crossed upper connecting rods are respectively connected by adopting a first connecting part and a second connecting part which are mutually independent. In some embodiments, a fixed connection may be used between the uprights and the upper connecting rods, and a movable connection may be used between intersecting upper connecting rods, so that the upper length and/or width of the body frame may be adjusted. As shown in fig. 1, the front uprights 11a and 11b are connected to both ends of the front upper connecting rod 12 by first connecting portions 27a and 27b, respectively, the rear uprights 21a and 21b are connected to the rear upper connecting rod 22 by first connecting portions 27c and 27d, respectively, and the first connecting portions 27a, 27b, 27c and 27d may be fixedly connected. The front upper connecting rod 12 and the side upper connecting rods 23a and 23b are connected by second connecting portions 24a and 24b, respectively, the rear upper connecting rod 22 and the side upper connecting rods 23a and 23b are connected by second connecting portions 24c and 24d, respectively, the second connecting portions 24a, 24b, 24c and 24d may be movably connected, taking the second connecting portion 24c as an example, as shown in the enlarged portion of the upper right corner of fig. 1, the ends of the rear upper connecting rod 22 and the side upper connecting rod 23a are respectively inserted into two through holes of the second connecting portion 24c and the rear upper connecting rod 22 may pass through the through hole, so that the second connecting portion 24c may move along the rear upper connecting rod 22 to the inside or the outside, thereby driving the rear portions of the side upper connecting rods 23a to move to the inside or the outside to adjust the upper width of the vehicle body frame. The connecting portions 24a, 24b, 24d may also have the same or similar structure as 24c, with the connecting portion 24d being movable inboard or outboard along the rear upper connecting rod 22 to thereby move the rear portion of the side upper connecting rod 23b inboard or outboard, and the connecting portions 24a, 24b being movable inboard or outboard respectively along the front upper connecting rod 12 to thereby move the front portions of the side upper connecting rods 23a, 23b inboard or outboard respectively. In the illustrated embodiment, the connection portions 24a, 24b are disposed on the inner sides of the connection portions 27a, 27b, respectively, and the connection portions 24c, 24d are disposed on the outer sides of the connection portions 27c, 27d, respectively.

In some embodiments, the uprights 11a, 11b, 21a and 21b are substantially perpendicular to the floor 10, and the body frame further comprises support bars 13a, 13b, 13c and 13d which connect the lower or middle portion of each of said uprights obliquely to the floor 10, respectively, to provide a stable triangular support for each of said uprights. For example, the support bar 13a is used as an example, and forms a triangular connection with the upright 11a and the bottom plate 10 to provide a stable triangular support for the upright 11 a. In some embodiments, the body frame further comprises: an inclined support bar 15a forming a triangular connection with the upright 11a and the front upper connecting rod 12, an inclined support bar 15b forming a triangular connection with the upright 11b and the front upper connecting rod 12, an inclined support bar 28a forming a triangular connection with the upright 21a and the rear upper connecting rod 22, and an inclined support bar 28b forming a triangular connection with the upright 21b and the rear upper connecting rod 22. In some embodiments, the body frame further comprises: a connecting rod 14 connecting the middle portions of the front uprights 11a and 11b, two connecting rods 26 and 29 connecting the middle portions of the rear uprights 21a and 21b, and two middle upper connecting rods 16 and 20 connecting the middle portions of the side upper connecting rods 23a and 23b, wherein the connecting rods 26 and 29 are parallel and the connecting rod 26 is closer to the rear upper connecting rod 22 and the connecting rod 29 is closer to the bottom plate 10, the connecting rods 16 and 20 are parallel and the connecting rod 16 is closer to the front upper connecting rod 12 and the connecting rod 20 is closer to the rear upper connecting rod 22.

As shown in fig. 2 and 5, the adjustable vehicle body 100 further includes a pedal assembly mounted on the floor 10, which includes an accelerator pedal 30, a driver foot pedal 31, and a passenger pedal 32. The three pedals are described below by taking the accelerator pedal 30 as an example. As shown in fig. 5, the position of the accelerator pedal 30 can be adjusted in the longitudinal direction (also referred to as the X-axis direction or the front-rear direction) through the waist-shaped hole 301, so as to meet the sitting posture requirements of different types of dummy of different vehicle models. The adjustable vehicle body 100 also includes position adjustable seat mounts 40a and 40b that allow the position of the simulated seat secured thereto to be adjusted relative to the floor 10. Taking the seat anchor 40a as an example, the X-axis direction hole slot 401a and the Y-axis direction hole slot 402a can adjust the position of the seat anchor 40a, and thus the seat fixed thereto, in the X-axis direction and the Y-axis direction. A sub dash mount 41 for simulating the fixing of the sub dash is provided beside the seat mount 40 b.

As shown in FIG. 2, the adjustable body 100 further includes position adjustable A-pillars 36a and 36b on either side of the body frame. The base 361a of the a-pillar 36a and the base 361b of the a-pillar 36b are respectively fitted with lateral grooves (only the lateral groove 37a corresponding to the base 361a is indicated) on the bottom plate 10 or on an a-pillar mounting portion fixed to the bottom plate 10, so as to be mounted on the bottom plate 10 movably in the lateral direction (which may also be referred to as the Y-axis direction, the lateral direction, or the left-right direction). In the illustrated embodiment, two transverse slots 37a are provided, spaced apart and parallel to each other, with the base of the a-pillar cooperating with the two transverse slots 37a to effect the transverse movement. The upper part 362a of the a-pillar 36a connects the base 361a and the side upper connecting rod 23a, and is rotatable about the base 361a and/or the side upper connecting rod 23 a. For example, in some embodiments, the upper portion 362a can rotate about the base 361a and also about the lateral upper connecting rod 23 a. Similarly, the upper portion 362b of the a-pillar 36b connects the base 361b and the lateral upper connecting rod 23b and is rotatable about the base 361b and/or the lateral upper connecting rod 23b, e.g., in some embodiments, the upper portion 362b is rotatable about the base 361b and also rotatable about the lateral upper connecting rod 23 b.

The adjustable vehicle body 100 further includes position adjustable B-pillars 33a and 33B on both sides of the body frame, respectively. The B-pillars 33a and 33B are closer to the rear of the vehicle body than the a-pillars 36a and 36B. The base portion 34a of the B-pillar 33a and the base portion 34B of the B-pillar 33B are mounted on the bottom plate 10 via B-pillar mounting portions (only the B-pillar mounting portion 38a corresponding to the base portion 34a is visible in the drawing), respectively. The B-pillar mounting portion 38a, which is visible in the drawings, will be described in detail below by way of example, and the mounting portion, which is not visible on the other side, may also have the same structure and function. The B-pillar mounting portion 38a is formed with a transverse slot 381a to allow the B-pillar base to move transversely relative to the B-pillar mounting portion 38a along the transverse slot 381 a. In the illustrated embodiment, the mounting portion 38a has three spaced apart and parallel transverse slots 381a with which the base of the B-pillar cooperates to effect lateral position adjustment. The upper portion 35a of the B-pillar 33a connects the base 34a and the side upper connecting rod 23a and is rotatable about the base 34a and/or the side upper connecting rod 23a, e.g., about the base 34a and also about the side upper connecting rod 23 a. Similarly, the upper portion 35B of the B-pillar 33B connects the base 34B and the side upper connecting rod 23B and is rotatable about the base 34B and/or the side upper connecting rod 23B, e.g., rotatable about the base 34B and also rotatable about the side upper connecting rod 23B. The A column and the B column move transversely through the base parts and drive the upper parts of the A column and the B column, and the distance between the A columns on two sides of the vehicle body frame and the distance between the B columns on two sides of the vehicle body frame can be adjusted to be suitable for different vehicle widths.

As shown in fig. 2 and 3, the B-pillar mounting portion 38a further defines one or more longitudinal elongated through slots (kidney-shaped holes) 382a, and the bottom plate 10 defines a row of two or more fixing holes 101a (only one of which is visible) corresponding to the through slots 382a, so as to allow a fastener to pass through the through slots 382a to be engaged with the corresponding fixing holes 101a of the bottom plate 10 after the B-pillar mounting portion 38a is adjusted in position in the longitudinal direction with respect to the bottom plate 10. The installation part can drive the B column installed on the installation part to move longitudinally relative to the bottom plate 10, and the test requirements of different wheelbases can be met. Other configurations described herein with a slotted hole may also be position adjusted in a similar manner. In some embodiments, the B-pillar upper portions 35a and 35B are also movable along the side upper connecting rods 23a and 23B, respectively, e.g., the connection between the B-pillar upper portion 35a and the side upper connecting rod 23a is slidable along the side upper connecting rod 23a in the loosened state, and the connection between the B-pillar upper portion 35B and the side upper connecting rod 23B is slidable along the side upper connecting rod 23B in the loosened state. It can be seen that in the illustrated embodiment, the position-adjustable B-pillars 33a and 33B are movable in both the X-axis direction and the Y-axis direction, so that the test requirements of different vehicle widths and different wheel bases can be met. In addition, the adjustable body 100 may further include connecting portions 39a and 39b for connecting with other components.

As shown in FIG. 4, adjustable vehicle body 100 also includes an adjustable windshield that includes a windshield 43 and a windshield frame 44 that mounts and secures windshield 43. One side edge of the windshield frame 44 is connected to the side upper connecting rod 23a through a rotatable connecting piece 42a (the connecting piece 42a can rotate around the side upper connecting rod 23 a), the other side edge is connected to the side upper connecting rod 23b through a rotatable connecting piece 42b, the rear edge is connected to the connecting rod 16 through rotatable connecting pieces 42c and 42d, the front edge is respectively connected to the body frame parts on both sides through a movable connecting piece 42e (only one side connecting piece 42e is visible in the figure), and the length of the connecting piece 42e can be adjusted to adjust the horizontal inclination angle of the windshield to meet the requirements of different vehicle types. The position (e.g., height) and/or angular relationship of the windshield 43 to the instrument panel (not shown) may be adjusted by the cooperation of the rotatable links 42a-42d and the adjustable length link 42e to meet the adjustment requirements of the instrument panel and windshield from car to SUV for various platforms. The positional relationship and/or the angular relationship between the windshield and the instrument panel greatly affect the deployment of the passenger side airbag, and are very important in a restraint system trolley simulation test. There is also a reserved location at the windshield frame 44 and connecting rod 42c where an overhead airbag can be installed, providing strong support for future development of new vehicle models and matching of overhead airbags on existing vehicle models. In addition, the adjustable vehicle body 100 further includes lifting points 45a, 45b, and 45c for traveling, an instrument panel support rod 46 for mounting an instrument panel, and an instrument panel positioning point 47 for positioning the instrument panel. The hoisting points 45a, 45b and 45c are respectively provided on the base plate 10. An instrument panel support rod 46 is mounted to the connecting rod 14, and an instrument panel positioning point 47 is mounted on the support rod 46.

The adjustable vehicle body in the embodiment of the invention is suitable for matching and optimizing a multi-project multi-platform early-stage constraint system, and can confirm collision waveforms and constraint system selection in advance, thereby shortening the project development period. The use of the adjustable body in the embodiment of the invention enables the adjustment test efficiency of the restraint system of the lifting trolley to be nearly 35%, and saves one body-in-white and the processing cost of the reinforced body for each project. When the test sample positioning device is used, the test sample positioning device can realize coordinate system conversion with a multi-project vehicle platform, accurately position the mounting hole position of a test sample of the multi-project vehicle platform, and the error between the mounting hole position and the mounting hole in a digital-analog model of a specific test project vehicle model is less than 3 mm. The positions of the A column, the B column and the windshield can be properly adjusted for vehicles with larger differences.

The above specific embodiments are provided so that the present disclosure will be thorough and complete, and the present invention is not limited to these specific embodiments. It will be understood by those skilled in the art that various changes, substitutions of equivalents, and alterations can be made herein without departing from the spirit of the invention and are intended to be within the scope of the invention.
