[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] In the description of the present invention, terms such as "up", "down", "left" and "right" indicating orientation, position and order are based on the orientation shown in the drawings, or are only for simplifying the description, and do not indicate or imply that the present invention must have a specific orientation, position and order.

[0021] like Figure 1 to Figure 3 As shown, this embodiment includes a support platform 1, a pitch-flip mechanism 2 and a pitch-flip locking mechanism 3, and a square cabin 4 located on both sides of the pitch-flip platform 1. A pitch frame 41 welded with square steel pipes is fixed on one side of the square cabin 4 and adjacent to both sides of the support platform 1. The top two corners of the pitch frame 41 are fixedly welded together by connecting beams 411 made of square steel pipes, so that the two square cabins 4 are connected into an integral structure, and synchronous pitch-flip can be achieved. The bottom shape of the square cabin 4 is the same as the bottom shape of the pitch frame 41, both of which are inverted trapezoids, which facilitates the rotation of the square cabin 4. A roller mechanism 42 is provided at the bottom center of the pitch frame 41, a roller 421 of the roller mechanism 42 is supported on a roller shaft 422, both ends of the roller shaft 422 are fixed on both sides of a roller seat 423, the bottom of the roller seat 423 is fixed at the bottom center of one side of the pitch frame 41, and the roller 421 abuts against an arc-shaped guide plate 43, which is respectively fixed on the lower part of both sides of the square cabin 4. The roller mechanism 42 makes the two square cabins 4 rotate more smoothly to avoid shaking.

[0022] The upper centers of both sides of the support platform 1 are respectively provided with hinge shafts 11 extending horizontally outward, and the hinge shafts 11 are respectively hinged to the hinge seats 44 at the centers of the corresponding sides of the cabin 4. The bottom of the support platform 1 is fixed to the bottom center of the vehicle platform 10 through four pressure plates 12.

[0023] The pitching and flipping mechanism 2 is arranged on a corner of the top of the support platform 1, and includes a screw rod 21, a reduction box 22, a drive motor 23 and a reduction box support seat 24. A flange 231 at one end of the drive motor 23 is fixed on the support platform 1. Figure 2 and Figure 3 The upper right end of the reduction box 22 shown in the figure, the horizontal hinge shafts 222 at the lower ends of both sides of the box body 221 are respectively hinged to the two ends of the reduction box support seat 24, and the bottom of the reduction box support seat 24 is fixed to the top corner of the support platform 1. The middle part of the screw rod 21 is screwed with the internal thread of the center of the final transmission gear in the reduction box 22, and the ball head 211 at one end of the screw rod 21 is hinged to the ball head seat 212, and the ball head seat 212 is fixed to one end of the cross bar 412 made of channel steel that vertically connects the two pitch frames 41. The drive motor 23 is a servo motor, which has the advantages of precise speed control, very hard torque speed characteristics, simple control principle and easy use, and can accurately control the flip angle of the cabin 4.

[0024] like Figure 3 As shown, the reduction box 22 includes a box body 221, a driving gear 222, a primary reduction transmission gear 223 and a secondary reduction transmission gear 224. The box body 221 is small at the top and large at the bottom. The drive motor shaft 232 extends into the upper end of the box body 221 and is fixedly connected to the driving gear 222 located in the upper end of the box body 221. The primary reduction transmission gear 223 is located in the middle of the box body 221. The primary reduction transmission gear 223 is supported on the mandrel 226 through the middle sleeve 225. The two ends of the mandrel 226 are fixedly connected to the box body 221 through the pressing plate 27 and the fastening screw 271 respectively. The two ends of the secondary reduction transmission gear 224 are supported on both sides of the lower end of the box body 221 through the lower sleeve 28 respectively. The middle of the screw rod 21 is screwed with the internal thread 29 at the center of the secondary reduction transmission gear 224. The ratio of the thickness B of the secondary reduction transmission gear 224 to the thickness B1 of the primary reduction transmission gear 223 is: B / B1=4.25, so that the internal thread 29 at the center of the secondary reduction transmission gear 224 has a sufficient screwing length with the screw rod 21, and the screw rod 21 is reliably supported.

[0025] like Figure 3 and Figure 4 As shown, the ball head 211 at one end of the screw rod 21 is hinged to one end of a transverse pin 213 which crosses both sides of the ball head seat 212, and the other end of the transverse pin 213 is riveted and fixed on both sides of the ball head seat 212.

[0026] like Figure 2 , Figure 3 and Figure 5As shown, the pitch and flip locking mechanism 3 is arranged on one side of the reduction gearbox support seat 24, including a locking pin 31, a locking seat 32, a locking plate 33 and a planar groove 214 in the middle of the screw rod 21, the locking plate 33 is in an inverted Z shape, the locking seat 32 is fixed on one side of the reduction gearbox support seat 24, the right end of the locking pin 31 abuts against the planar groove 214 in the middle of the screw rod 21, the middle part of the locking pin 31 is supported on the locking seat 32, the left end of the locking pin 31 abuts against the middle part of the locking plate 33, and the bottom of the locking plate 33 is fixed to one side of the pitch frame 41 by a fastening screw 34.

[0027] When the cabin 4 is pitched and flipped, the locking pin 31 first disengages from the plane groove 214 in the middle of the screw rod 21, and the screw rod 21 is released from the constraint. Then the drive motor 23 is powered on, and the drive motor shaft 232 drives the active gear 222 to rotate, and the active gear 222 drives the secondary reduction transmission gear 224 to rotate through the primary reduction transmission gear 223, so that the screw rod 21 moves to the right, and the cross bar 412 is pushed through the ball head 211 and the ball head seat 212, so that the two pitch frames 41 synchronously push the connected cabins 4 to rotate around the center of the hinge shaft 11 on both sides of the support platform 1, and the maximum rotation angle is ±28°. After the cabin 4 rotates to the required angle, push the locking pin 31 so that its end rests on the plane groove 214 in the middle of the screw rod 21, and then fix the locking plate 33 to limit the movement of the locking pin 31, so that the screw rod 21 cannot move, thereby locking the cabin 4 in a tilted state of use.

[0028] In addition to the above embodiments, the present invention may also have other implementation modes. Any technical solutions formed by equivalent replacement or equivalent transformation shall fall within the protection scope required by the present invention.
