In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0028] This embodiment provides a vehicle seat test fixture. Figures 1 to 6 As shown, it includes: a base 10, a mounting seat 20, a heightening pad 30 and a connecting member 40. The mounting seat 20 is connected to the base 10, and a plurality of mounting seats 20 are provided. The plurality of mounting seats 20 are arranged in rows along the x direction and in columns along the y direction, and form a plurality of rows and columns. At least one row of mounting seats 20 located at the edge is movably arranged along the x direction, and at least one row of mounting seats 20 located at the edge is movably arranged along the y direction. The heightening pad 30 is detachably arranged between the base 10 and the mounting seat 20; the connecting member 40 has a connecting surface 41, and the connecting member 40 is rotatably arranged on the mounting seat 20 so that the connecting surface 41 has different inclination angles.

[0029] By applying the vehicle seat test fixture of the present embodiment, at least one row of mounting seats 20 located at the edge is movably arranged along the x direction, so that the size of the vehicle seat test fixture along the x direction can be adjusted, and at least one row of mounting seats 20 located at the edge is movably arranged along the y direction, so that the size of the vehicle seat test fixture along the y direction can be adjusted, and the height of the mounting seat 20 is adjusted by arranging a heightening pad 30, so that the connecting member 40 can be rotatably arranged relative to the mounting seat 20 to adjust the installation angle of the seat, thereby making the vehicle seat test fixture compatible with various types of seats. Therefore, there is no need to redevelop a new fixture for a new type of seat, thereby improving the development efficiency of the seat.

[0030] Furthermore, the vehicle seat test fixture of the present embodiment can be adapted to various types of seats, thereby reducing R&D costs, tooling costs, and storage space for test tooling.

[0031] like Figure 1As shown, in the technical solution of this embodiment, four mounting seats 20 are provided, and the four mounting seats 20 form two rows and two columns. Specifically, two mounting seats 20 are provided in each row, and two mounting seats 20 are provided in each column. One row of mounting seats 20 in the two columns of mounting seats 20 is movably provided along the x direction, and one row of mounting seats 20 in the two rows of mounting seats 20 is movably provided along the y direction.

[0032] Of course, in other alternative embodiments, the number of rows and columns formed by the arrangement of a plurality of mounting seats 20 can be specifically set according to actual needs; further, the number of rows and columns can be the same or different, such as three rows and three columns, three rows and two columns, etc.

[0033] like Figure 1 , Figure 4 and Figure 5 As shown, in the technical solution of this embodiment, the mounting seat 20 includes a first seat body 21 and a second seat body 22, the first seat body 21 is fixedly arranged in the x direction, and the second seat body 22 is provided with a first strip hole 221 along the x direction, and the vehicle seat test fixing device also includes a first fastener, the first fastener passes through the first strip hole 221 and is fastened to the base 10, and the position of the first fastener in the first strip hole 221 is adjustable to adjust the position of the second seat body 22 along the x direction.

[0034] Specifically, Figure 1 As shown, in the technical solution of this embodiment, one row of mounting seats 20 in the two rows of mounting seats 20 is a first seat body 21 , and the other row of mounting seats 20 in the two rows of mounting seats 20 is a second seat body 22 .

[0035] In this way, the row of mounting seats 20 located at the edge can be movably arranged along the x-direction. Of course, in other alternative embodiments, the two rows of mounting seats 20 located at the edge can be movably arranged along the x-direction; further, when the number of rows of mounting seats 20 is greater than or equal to three rows, the row or rows of mounting seats 20 located between the two side edges can be fixed in the x-direction, or can be movably arranged along the x-direction.

[0036] It is worth noting that when the position of the second seat body 22 in the x-direction needs to be adjusted, the first fastener is loosened so that the second seat body 22 can move relative to the base 10, thereby moving the second seat body 22 along the x-direction. At this time, the first fastener moves relatively in the first strip hole 221 along the x-direction. When the second seat body 22 moves to the appropriate position, the first fastener is retightened to fix the second seat body 22 on the base 10.

[0037] like Figure 1 and Figure 2As shown, in the technical scheme of this embodiment, a second strip hole 11 is opened on the base 10 along the y direction, and the second strip holes 11 are opened in at least one row, and at least a row of mounting seats 20 located at the edge is arranged corresponding to a row of second strip holes 11. The vehicle seat test fixing device also includes a second fastener, and the second fastener is arranged corresponding to the first seat body 21 in the row of mounting seats 20 located at the edge. The second fastener passes through the first seat body 21 and is inserted in the second strip hole 11. The position of the second fastener in the second strip hole 11 is adjustable to adjust the position of the first seat body 21 along the y direction. The first fastener corresponding to the second seat body 22 in the row of mounting seats 20 located at the edge is inserted in the second strip hole 11, and the position of the first fastener in the second strip hole 11 is adjustable to adjust the position of the second seat body 22 along the y direction.

[0038] It is worth noting that the first base 21 does not need to move along the x-direction. If the first base 21 needs to move along the y-direction, it is achieved through the second strip hole 11 opened on the base 10. Figure 1 and Figure 5 As shown, the first seat body 21 is provided with a first circular hole 211 for connecting with the base 10 .

[0039] Specifically, Figure 1 As shown, in the technical solution of this embodiment, one row of mounting seats 20 in the two rows of mounting seats 20 is arranged corresponding to the base 10 through a row of second strip holes 11 .

[0040] In this way, the row of mounting seats 20 located at the edge can be movably arranged along the y direction. Of course, in other alternative embodiments, the two rows of mounting seats 20 located at the edge can be movably arranged along the y direction, that is, the second strip-shaped holes 11 are provided with two rows; further, when the number of rows of mounting seats 20 is greater than or equal to three rows, the row or rows of mounting seats 20 located between the two side edges can be fixed in the y direction, or can be movably arranged along the y direction.

[0041] It is worth noting that when the position of the mounting base 20 in the y direction needs to be adjusted, the second fastener on the first base body 21 is loosened or the first fastener on the second base body 22 is loosened, so that the mounting base 20 (which may be the first base body 21 or the second base body 22) can be moved relative to the base 10, thereby moving the mounting base 20 along the y direction. At this time, the second fastener or the first fastener moves along the y direction in the second strip hole 11. When the mounting base 20 moves to the appropriate position, the second fastener or the first fastener is retightened to fix the mounting base 20 on the base 10.

[0042] Specifically, see Figure 1 , for the x direction, along Figure 1In the direction indicated by the middle arrow, the two rows of mounting seats 20 are respectively the first row and the second row, wherein the first row of mounting seats 20 are all first seat bodies 21, and the second row of mounting seats 20 are all second seat bodies 22, that is, the first row of mounting seats 20 are fixedly arranged in the x direction, and the second row of mounting seats 20 are movable along the x direction; for the y direction, along Figure 1 In the direction indicated by the middle arrow, the two rows of mounting seats 20 are respectively the first row and the second row, wherein the mounting seats 20 in the first row are fixedly arranged in the y direction, and the mounting seats 20 in the second row are movably arranged in the y direction. In this arrangement, the mounting seats 20 located in the first column of the first row (this mounting seat 20 is the first seat body 21) are fixed on the base 10, the mounting seats 20 located in the second column of the first row (this mounting seat 20 is the second seat body 22) are movably arranged in the x direction, the mounting seats 20 located in the first column of the second row (this mounting seat 20 is the first seat body 21) are movably arranged in the y direction, and the mounting seats 20 located in the second column of the second row (this mounting seat 20 is the second seat body 22) can move in both the x direction and the y direction.

[0043] Correspondingly, such as Figure 2 As shown, on the base 10 , a row of circular mounting holes 14 is provided corresponding to the first row of mounting seats 20 , and a row of second strip holes 11 is provided corresponding to the second row of mounting seats 20 . The mounting seat 20 located in the first row and the first column is connected to the base 10 through a fourth fastener. Specifically, the fourth fastener penetrates the first circular hole 211 and the circular mounting hole 14 at the same time, and fastens the mounting seat 20 and the base 10 together; the mounting seat 20 located in the first row and the second column is connected to the base 10 through a first fastener. Specifically, the first fastener penetrates the first strip hole 221 and the circular mounting hole 14 at the same time, and is suitable for fastening the mounting seat 20 and the base 10 together; the mounting seat 20 located in the second row and the first column is connected to the base 10 through a second fastener. Specifically, the second fastener penetrates the first circular hole 211 and the second strip hole 11 at the same time, and is suitable for fastening the mounting seat 20 and the base 10 together; the mounting seat 20 located in the second row and the second column is connected to the base 10 through a first fastener. Specifically, the first fastener penetrates the first strip hole 221 and the second strip hole 11 at the same time, and is suitable for fastening the mounting seat 20 and the base 10 together.

[0044] It is understandable that for the mounting seat 20 located at the second row and the second column, that is, the mounting seat 20 that can move in both the x-direction and the y-direction, a person skilled in the art can know how to adjust the position of the mounting seat 20 in the x-direction and the y-direction to ensure that the mounting seat 20 is at a predetermined position in the x-direction and the y-direction. For example, the mounting seat 20 is first adjusted to a desired position in the x-direction, and the mounting seat 20 and the base 10 are pre-fastened by a first fastener (so that the mounting seat 20 will not move at will and can move after an external force is applied), and then a force in the y-direction is applied to the mounting seat 20, so that the mounting seat 20 is adjusted to a predetermined position in the y-direction.

[0045] like Figure 1 as well as Figures 4 to 6 As shown, in the technical solution of this embodiment, an arc-shaped hole 42 is provided on the connecting member 40 and / or the mounting seat 20, and the fixing device for vehicle seat testing also includes a third fastener, which is inserted into the arc-shaped hole 42 and connects the connecting member 40 and the mounting seat 20, and the position of the third fastener in the arc-shaped hole 42 is adjustable to adjust the inclination angle of the connecting surface 41.

[0046] Specifically, Figures 4 to 6 As shown, in the technical solution of this embodiment, a first rotating hole 44 is formed on the connecting member 40, a second rotating hole 25 is formed on the mounting seat 20, and the rotating shaft passes through the first rotating hole 44 and the second rotating hole 25 at the same time, so as to rotatably connect the connecting member 40 and the mounting seat 20. Further, an arc hole 42 is formed on the connecting member 40, a second circular hole 26 is formed on the mounting seat 20, and a third fastener passes through the arc hole 42 and the second circular hole 26 at the same time.

[0047] It should be noted that when the inclination angle of the connecting surface 41 needs to be adjusted, the third fastener is loosened to allow the connecting member 40 to rotate relative to the mounting seat 20. When the connecting member 40 rotates, the third fastener moves relatively in the arc hole 42. When the connecting member 40 rotates to the appropriate position, the third fastener is retightened to fix the connecting member 40 on the mounting seat 20.

[0048] Of course, in other alternative embodiments, the arc hole 42 may be formed on the mounting seat 20 , and correspondingly, the second circular hole 26 may be formed on the connecting member 40 ; or, the arc hole 42 may be formed on both the connecting member 40 and the mounting seat 20 .

[0049] It should be noted that, in the technical solution of this embodiment, the first fastener, the second fastener, the third fastener and the fourth fastener can all be a combination of bolts and nuts.

[0050] like Figure 6As shown, in the technical solution of this embodiment, the connecting member 40 is provided with a fixing hole 43, and the fixing hole 43 is arranged corresponding to the connecting surface 41.

In this way, the connecting member 40 is clamped and limited by the pair of vertical plates 24, thereby improving the stability of the connecting member 40.

[0052] Further, such as Figure 4 and Figure 5 As shown, the vertical plate 24 is vertically connected to the horizontal plate 23 , and a pair of vertical plates 24 is arranged corresponding to the middle position of the horizontal plate 23 , that is, both ends of the horizontal plate 23 extend out of the vertical plates 24 .

[0053] It is worth mentioning that please refer to Figure 4 and Figure 5 The second rotating hole 25 and the second circular hole 26 are both formed on the vertical plate 24. Figure 5 For the first seat body 21, the first circular hole 211 is opened on the horizontal plate 23, and a plurality of first circular holes 211 are opened along the four sides of the horizontal plate 23.
