[0016] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] In order to illustrate the technical solution of the present invention, specific embodiments are provided below.

[0018] Example 1

[0019] like Figures 1 to 3As shown, the four-way shuttle vehicle of this embodiment includes a seat 1, two transverse wheel sets 2, two longitudinal wheel sets 3, two lifting plates 4, a lifting motor 5, a cam 6, a driving motor 7, a transverse shaft 8, a longitudinal shaft 9, a direction-changing gear set 10, two gear boxes 11 and two universal joints 12. The longitudinal wheel set 3 is rotatably mounted on the left and right sides of the seat 1, the two lifting plates 4 are vertically slidably mounted on the front and rear sides of the seat 1, the lifting plates 4 are provided with a through slot 41, the two gear boxes 11 are mounted on the seat 1 and driven by a transmission. The shaft 13 is connected for transmission, the cam 6 is installed in the through groove 41 and is connected to the output end of the gear box 11, the lifting motor 5 is installed on the seat 1 and is connected to the input end of the gear box 11, the drive motor 7 is installed on the seat 1 and is connected to the longitudinal wheel set 3 through the transverse shaft 8, the longitudinal shaft 9 is rotatably installed on the seat 1 and is connected to the transverse shaft 8 through the changing gear set 10, and the two ends of the longitudinal shaft 9 are connected to the transverse gear set 2 through the universal joint 12. During operation, the drive motor 7 rotates the transverse shaft 8, which in turn rotates the two longitudinal gear sets 3, achieving forward and backward movement of the four-way shuttle. When lateral movement is required, since the longitudinal shaft 9 is connected to the transverse shaft 8 via the direction-changing gear set 10, the rotation of the transverse shaft 8 also drives the rotation of the longitudinal shaft 9. The rotation of the longitudinal shaft 9 drives the rotation of the transverse gear set 2, which in turn rotates the lifting motor 5. The two gear boxes 11 drive the corresponding cams 6 to rotate. The cams 6 rotate and press into the through slots 41, causing the lifting plate 4 to move downward, causing the transverse wheel set 2 to move downward and contact the ground level, and driving the vehicle seat 1 to move upward, causing the longitudinal wheel set 3 to leave the ground. The transverse wheel set 2 drives the four-way shuttle left and right. Since the transverse wheel set 2 is connected to the longitudinal shaft 3 via the universal coupling 12, the transverse wheel set 2 can maintain a transmission connection with the longitudinal shaft 9 even if it moves downward. The four-way shuttle of this embodiment uses the lifting motor to drive the corresponding cams through the two gear boxes to rotate, causing the transverse gears to rise synchronously, effectively improving the smooth operation of the four-way shuttle.

[0020] In this embodiment, the two gearboxes 11 are arranged in parallel and located between the two lifting plates 4, making the overall structure more balanced. The direction-changing gear set 10 includes a first bevel gear 101 and a second bevel gear 102. The first bevel gear 101 is mounted on the transverse shaft 8. The second bevel gear 102 is mounted on the seat 1 via a rotating shaft 103 and meshes with the first bevel gear 102. The rotating shaft 103 is connected to the longitudinal shaft 9 through a meshing gear set 104. The first bevel gear 101 and the second bevel gear 102 are combined to achieve axial movement between the transverse shaft 8 and the longitudinal shaft 9.

[0021] In this embodiment, slide rails 14 are provided at both ends of the front and rear sides of the seat 1, and sliders 42 are provided at both ends of the lifting plate 4. The sliders 42 are slidably mounted on the slide rails 14. The cooperation between the sliders 42 and the slide rails 14 facilitates the up and down movement of the lifting plate 4 on the support 1. There are two through slots 41, which are symmetrically distributed on the lifting plate 4 and located between the two transverse wheels of the transverse wheel set 2. There are two cams 6, which are respectively arranged in the two through slots 41. The lifting of the lifting plate 4 by the two cams 6 makes the force on the lifting plate 4 more uniform and the lifting more stable. The longitudinal wheel set 3 includes a plurality of longitudinal wheels mounted on the seat 1. The plurality of longitudinal wheels are connected to the transverse shaft 8 through a sprocket structure, so that the rotation speed of the plurality of longitudinal wheels remains consistent, and the movement of the entire vehicle is smooth and stable.

[0022] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
