Referring to fig. 1 to 5, a description will now be given of a horizontal overturning testing device for an attitude acquisition module provided by the present utility model. The gesture acquisition module horizontal overturning testing device comprises a base 10 and a supporting block 20; the base 10 is used for supporting on an operation platform or the ground, and the top surface of the base 10 is provided with a horizontal receiving area 101; the supporting block 20 comprises a mounting plane 204 for attaching and fixing the module 50 to be tested, a first supporting surface 201 opposite to the mounting plane 204 and distributed in parallel, and a second supporting surface 202 and a third supporting surface 203; the first supporting surface 201, the second supporting surface 202 and the third supporting surface 203 are perpendicular to each other; the support block 20 has a Z-axis test state in which the first support surface 201 is placed on the horizontal receiving area 101, a Y-axis test state in which the second support surface 202 is placed on the horizontal receiving area 101, and an X-axis test state in which the third support surface 203 is placed on the horizontal receiving area 101.

It should be understood that the horizontal receiving area 101 on the base 10 in this embodiment can be actually understood as an area with flatness meeting the requirement of fitting with the module 50 to be tested, and then adjusted to obtain the horizontal state based on the supporting state of the base 10 relative to the supporting surface, i.e. the working platform or the ground.

On the basis of ensuring that the horizontal receiving area 101 is in a horizontal state, when the first supporting surface 201 is attached to the horizontal receiving area 101, the horizontal state (namely, the vertical state of a Z axis) of the module 50 to be tested can be ensured, after the Z axis test is completed, the Y axis vertical state of the module 50 to be tested can be ensured by turning over the supporting block 20 until the second supporting surface 202 is attached to the horizontal receiving area 101, and likewise, after the Y axis test is completed, the X axis vertical state of the module 50 to be tested can be ensured by turning over the supporting block 20 until the third supporting surface 203 is attached to the horizontal receiving area 101; that is, the horizontal flip test operation of the module 50 to be tested can be completed by flipping the supporting block 20 twice.

Specifically, in this embodiment, the supporting block 20 may be a regular hexahedral structure or a square structure, or four planes may be machined on the sphere to be respectively used as the mounting plane 204 and the three supporting surfaces, or may be a block structure with other shapes, and it is only required to satisfy a block structure having two planes parallel at intervals as the mounting plane 204 and the first supporting surface 201, and two planes perpendicular to each other and perpendicular to the first supporting surface 201 as the second supporting surface 202 and the third supporting surface 203.

Compared with the prior art, the horizontal overturning testing device for the gesture collection module provided by the embodiment uses the horizontal bearing area 101 on the top surface of the base 10 to directly stick the supporting block 20 to the horizontal bearing area 101 by the first supporting surface 201 or the second supporting surface 202 or the third supporting surface 203, so that the Z-axis numerical testing or Y-axis numerical testing or X-axis numerical testing can be performed on the module 50 to be tested fixed on the mounting plane 204, and the three supporting surfaces are perpendicular to each other, and the mounting plane 204 is parallel to the first supporting surface 201, so that the testing result precision of the Z-axis, the Y-axis and the X-axis of the module 50 to be tested can be ensured, the manual testing error is reduced, the switching of each testing state can be performed only by overturning the supporting block 20, the operation is simple and efficient, the testing process does not need an operator to support the module 50 to be tested, the device is suitable for single testing operation, the whole structure is simple, the cost is low, the carrying and the transferring is convenient, and the flexibility of the testing operation can be improved.

Specifically, the internal thread fastener 22 may directly adopt a nut, and a counter bore suitable for embedding the internal thread fastener 22 is formed on the mounting plane 204, and meanwhile, in order to avoid the falling-off of the internal thread fastener 22, the counter bore and/or the internal thread fastener 22 may be coated with a glue for bonding when embedded, so that the detachable connection of the positioning column 21 may be realized by using the threaded engagement of the internal thread fastener 22 and the positioning column 21, and thus, the corresponding positioning column 21 may be replaced according to the differences of the mounting holes 501 of different modules 50 to be tested, thereby improving flexibility and versatility.
