[0045] A fixed structure is provided on the free surface 6 of the vehicle body 1, and the first free end of the movable rod 4 passes through the fixed structure, wherein the first free end is an end of the movable rod 4 movably connected to the vehicle body 1; and the movable rod 4 can rotate. Specifically, a protrusion is provided above the first free end of the movable rod 4, and the fixed structure includes a first limiting groove and a second limiting groove, and the protrusion can be located in the first limiting groove or the second limiting groove by rotation; when the protrusion is located in the first limiting groove, the vehicle body 1 is in a state where the test board 7 can be placed, that is, the free surface 6 of the vehicle body 1 is in an open state; when the protrusion is located in the second limiting groove, it is a limiting state of the free surface 6 of the vehicle body 1, that is, the movable rods 4 on both sides of the vehicle body 1 are located on the free surface 6, and form an obstacle to the movement of the test board 7. Furthermore, when the protrusion is located in the first limiting groove, the operator can place the test board 7 into the first placement area 3 on the free surface 6; after the test board 7 is placed in the first placement area 3, the movable rod 4 is rotated to make the protrusion located in the second limiting groove and limit the free surface 6 so that the test board 7 cannot fall from one side of the free surface 6.

[0046] The roller 2 is disposed at the bottom of the vehicle body 1 and is used to drive the vehicle body 1 to move. In one specific embodiment, four rollers 2 are provided and are located at four corners of the bottom of the vehicle body 1. In another specific implementation, the roller 2 is a universal wheel that can drive the vehicle body 1 to move in multiple directions. In another specific embodiment, the roller 2 is cylindrical and has a larger contact area with the ground, which can be transported more smoothly.

[0047] like Figure 2 As shown, specifically, the resettable device 5 is arranged in the groove structure 13 and is arranged opposite to the free surface 6; if the free surface 6 is located on the side of the vehicle body 1 where the movable rod 4 is provided, the resettable device 5 is arranged on the other side of the vehicle body 1. More specifically, if the free surface 6 is provided on the front side of the vehicle body 1, the resettable device 5 is provided on the rear side of the vehicle body 1. The free surface 6 is limited by the movable rod 4, and the resettable device 5 limits the side of the test plate 7 relative to the free surface 6; after the test plate 7 is placed on the vehicle body 1, the movable rod 4 and the resettable device 5 together limit the test plate 7 on the vehicle body 1, so as to prevent the test plate 7 from sliding off the vehicle body 1 when encountering an uneven road surface or moving too fast. As shown Figure 3 As shown, the resettable device 5 includes a reset member 51 and a movable structure 52. In a specific embodiment, the reset member 51 is a torsion spring and is elastic; the movable structure 52 is in the shape of a sheet, which can reduce the space occupied in the first placement area 3. The reset member 51 is fixed in the first placement area 3 and is fixed to the movable structure 52. The movable structure 52 rotates in the first placement area 3 under the action of force. At this time, the reset member 51 is squeezed by the action of the movable structure 52 and then deformed. When the movable structure 52 is in the initial position, that is, it is arranged in the first placement area 3, it blocks the movement of the test plate 7, thereby limiting the test plate 7.

[0048] like Figure 2 As shown, specifically, a plurality of groove structures 13 are respectively arranged on both sides of the interior of the vehicle body 1; the groove openings 131 of the plurality of groove structures 13 correspond to each other, and the corresponding groove openings 131 constitute a first placement area 3, and the test board 7 is respectively placed in the groove openings 131, and the groove openings 131 support the test board 7. The length of the groove structure 13 is greater than the length of the test board 7, so that the test board 7 can have a movable space in the groove structure 13. In a specific embodiment, the operator places the left and right sides of the test board 7 in the groove openings 131, and then pushes the test board 7 to slide in the groove structure 13. The groove structure 13 is provided to facilitate the sliding of the test board 7 and the pushing out of the test board 7 for testing.

[0049] In one embodiment, a box body 8 is further included, and the box body 8 is provided with a slot 81 for placing the test board 7.

[0050] like Figure 4As shown, specifically, the operator pushes the vehicle body 1 to the box body 8, and the side provided with the resettable device 5 is close to the box body 8. After the vehicle body 1 is aligned and placed with the box body 8, the test board 7 is pushed so that the test board 7 presses the resettable device 5, and the resettable device 5 rotates toward one side of the box body 8, and then the test board 7 is pushed further until it slides into the slot 81 provided in the box body 8, so that the test board 7 can be tested.

[0051] like Figure 3 As shown, in one embodiment, the groove structure 13 includes a chamber 53, one end of the reset member 51 is fixed in the chamber 53, and the other end is fixedly connected to the movable structure 52; Figure 6 and Figure 7 As shown, fixing holes 11 and fixing columns 12 are respectively provided on both sides of the chamber 53, and the fixing holes 11 and the fixing columns 12 are arranged on the side close to the free surface 6, and the mounting columns 12 respectively penetrate the fixing holes 11 and move in the fixing holes 11; the mounting columns 511 are provided with a deformation portion 513, and the deformation portion 513 is sleeved on the outside of the fixing columns 12; the deformation portion 513 is provided with a protrusion, and the movable structure 52 is provided with a slot, and the protrusion is engaged in the slot; the protrusion and the movable structure 52 are respectively provided with through holes, and the movable structure 52 is provided with a fixing pin 522 corresponding to the through hole, and the fixing pin 522 is embedded in the through hole.

[0052] Specifically, Figure 3 As shown, the groove structure 13 is provided with a chamber 53, which is used to prevent the movable structure 52 from abutting against the groove structure 13 after rotation, causing wear. The inner wall of the chamber 53 is provided with a fixing hole 11 and a fixing column 12 on both sides, and is arranged on the side close to the free surface 6, so that after the test plate 7 is pushed, the test plate 7 can push the movable structure 52 into the chamber 53; the installation column 511 provided on the reset member 51 is respectively inserted into the fixing hole 11 provided in the chamber 53, so that the reset member 51 is fixed to the vehicle body 1; the installation column 511 can rotate in the fixing hole 11; while installing the reset member 51, it is also necessary to make the deformation part 513 provided on the reset member 51 be sleeved on the outer side of the fixing column 12 provided in the chamber 53, so as to further fix the reset member 51. The deformation part 513 is also provided with a protrusion, and can be moved by squeezing the deformation part 513. In a specific embodiment, there are two deformation parts 513, and the protrusion is fixed in the middle position of the two deformation parts 513. The movable structure 52 is provided with a slot, and the protrusion provided on the reset member 51 is inserted into the slot, and the movable structure 52 and the reset member 51 are further installed and fixed by the fixing pin 522.

[0053] More specifically, if Figure 3 and Figure 7As shown, the reset member 51 is provided with a first through hole 512, and the movable structure 52 is provided with a second through hole 521 and a fixing pin 522. During installation, the installation columns 511 are respectively inserted into the fixing holes 11, and the deformation portion 513 is sleeved on the outside of the fixing column 12, the protrusion of the reset member 51 is inserted into the slot provided in the movable structure 52, and the second through hole 521 provided in the movable structure 52 is aligned with the first through hole 512 provided in the reset member 51, and finally the fixing pin 522 is inserted into the first through hole 512 and the second through hole 521, so that the movable structure 52 is fixed on the reset member 51.

[0054] In one embodiment, when the movable structure 52 is in the groove structure 13 and is located in the first position, it is used to limit the test board 7; when the movable structure 52 is in the groove structure 13 and is located in the second position, the movable structure 52 is located in the chamber 53, and the free end of the movable structure 52 faces the side of the box 8, which is used to allow the test board 7 to pass.

[0055] Specifically, Figure 3 As shown, at this time, the movable structure 52 is located at the first position. In practical applications, the first position is that the movable structure 52 is vertically arranged on the groove structure 13 and limits the position of the test board 7 to prevent the test board 7 from falling out. Figure 8 As shown, the movable structure 52 is located in the second position, and the second position is a position to ensure that the test board 7 can pass through the groove structure 13. After being pushed by the test board 7, the free end of the movable structure 52 will rotate in the direction of the chamber 53. At this time, the test board 7 and the movable structure 52 are in contact. The reset member 51 will be deformed and rotated under the drive of the movable structure 52 until the movable structure 52 is located in the chamber 53. The test board 7 can pass between the movable structure 52 and the groove structure 13. At this time, the restriction of the test board 7 by the movable structure 52 is released. After the test board 7 is pushed out, the reset member 51 will reset and drive the movable structure 52 to reset. At this time, the free end of the movable structure 52 will rotate in the opposite direction of the chamber 53 until it returns to the first position and restricts the test board 7 again.

[0056] In one embodiment, the process of the movable structure 52 moving from the first position to the second position in the groove structure 13 includes: applying a propulsion force to the test board 7, the test board 7 moves toward one side of the box 8, and the test board 7 drives the movable structure 52 to rotate to the second position.

[0057] Specifically, Figure 3As shown, the movable structure 52 is vertically arranged in the groove structure 13 and is located in the first position. When the vehicle body 1 is moving, when the test plate 7 slides in the groove structure 13 until it contacts the movable structure 52, the movable structure 52 will generate resistance to the test plate 7, so that the test plate 7 will not pass through the movable structure 52, thereby limiting the test plate 7, and the resistance is greater than the propulsion force generated by the test plate 7 moving toward the movable structure 52 during the normal movement of the vehicle body 1, thereby preventing the test plate 7 from falling during the normal movement; and the magnitude of the resistance can be set by the reset member 51. When the reset member 51 is a torsion spring, the resistance can be adjusted by the material, spring wire diameter, number of turns, preload, etc., and adjusted to be greater than the moving force generated during the normal movement of the test plate 7. When the operator applies a propulsion force greater than the resistance of the active structure 52 to the test board 7, the test board 7 will contact the active structure 52 and move together with the active structure 52 toward the box 8 until the active structure 52 is in the chamber 53. The test board 7 can slide out of the groove structure 13 to the box 8. At this time, the active structure 52 rotates from the first position to the second position. During this period, the active structure 52 continuously presses the reset member 51 until the active structure 52 reaches the chamber 53 and the test board 7 can pass between the active structure 52 and the groove structure 13.

[0058] In one embodiment, the groove structure 13 also includes: a top plate 132, the top plate 132 is located on the inner wall of the groove structure 13, and a first preset distance is set between the top plate 132 and the first surface of the inner wall of the groove structure 13; a second preset distance is set between the top plate 132 and the second surface of the inner wall to form a second placement area 135; a limiting plate 133, the limiting plate 133 is located in the second placement area 135, the limiting plate 133 can be movable in the second placement area 135, and the limiting plate 133 is used to push the movable structure 52 to the second position.

[0059] Specifically, Figure 8 As shown, a first preset distance is set between the top plate 132 and the first surface of the groove structure 13, the first surface is the lower surface of the inner wall of the groove structure 13, and the distance between the lower surface of the top plate 132 and the lower surface of the inner wall of the groove structure 13 is the first preset distance, so as to form a first placement area 3; the first preset distance is set to ensure that the test board 7 can be placed in the groove structure 13 and can pass smoothly in the first placement area 3. A second preset distance is set between the upper surface of the top plate 132 and the second surface of the groove structure 13 to form a second placement area 135; wherein the second surface is the upper surface of the inner wall of the groove structure 13, and the second preset distance is the distance between the upper surface of the groove structure 13 and the top plate 132; the second preset distance forms the second placement area 135 in the groove structure 13, so as to ensure that the limiting plate 133 can pass smoothly in the second placement area 135.

[0060] In a specific embodiment, the limit plate 133 is disposed above the top plate 132 and is located in the second placement area 135, and the limit plate 133 can move in the second placement area 135. When taking out the tested test board 7, the operator pushes the limit plate 133 toward the side with the resettable device 5, so that the limit plate 133 moves on the top plate 132 and abuts against the movable structure 52, and then applies a thrust to the movable structure 52. After the movable structure 52 is pushed by the limit plate 133, its free end will rotate toward the direction of the chamber 53, and the rotation angle is greater than the rotation angle when the test board 7 pushes the movable structure 52. The reset member 51 will be deformed under the drive of the movable structure 52 until the movable structure 52 is pushed to the chamber 53 and above the limit plate 133. The test board 7 can slide from the box 8 to the vehicle body 1. At this time, the movable structure 52 is in the second position. After the test board 7 is placed on the vehicle body 1 , the limit plate 133 is moved toward the free surface 6 . At this time, the reset member 51 is reset, and the free end of the movable structure 52 rotates in the opposite direction of the chamber 53 until it returns to the first position and limits the test board 7 again.

[0061] In one embodiment, a limiting block 134 for limiting the limiting plate 133 is disposed in the groove structure 13 ; the limiting block 134 is disposed on a side facing the box body 8 ; and the limiting block 134 is used to limit the limiting plate 133 .

[0062] Specifically, Figure 8 As shown, the limit block 134 is arranged on the sliding track of the limit plate 133 and is close to one side of the box body 8; the limit plate 133 can be pushed toward one side of the box body 8 and abut against the limit block 134, and at this time, the movable structure 52 is located above the limit plate 133. The limit block 134 can limit the moving distance of the limit plate 133 to prevent the movable structure 52 from not being completely above the limit plate 133 after being pushed by the limit plate 133, and from generating friction with the test board 7, thereby causing damage to the test board 7.
