[0029] Specifically, Figure 3 As shown, the fixing hook mechanism 5 can be two groups, which are respectively arranged at the two ends of the swing plate 2 along the Y-axis direction. The two groups of fixing hook mechanisms 5 are connected to the transition plate 9 at the same time, further improving the stability of the connection between the swing plate 2 and the transport warehouse transition plate 9; the size of the telescopic ladder 4 along the Y-axis direction can correspond to the width of the car wheel. By setting the telescopic ladder 4 as two, the two telescopic ladders 4 are arranged along the Y-axis direction, corresponding to the two wheels of the car in the width direction respectively, and the car can drive in or out of the inclined bracket 3 through the two telescopic ladders 4. In this way, the size of the telescopic ladder 4 can be reduced, which is convenient for driving the telescopic ladder 4 to slide and rotate relative to the inclined bracket 3, while saving materials.

[0030] Alternatively, if Figure 4As shown, a limiting groove 22 is provided on the front end surface of the swing plate 2, and the limiting groove 22 and the fixing groove 515 are used to be plugged and matched with the front and rear ends of the transition plate 9 respectively.

[0031] In this embodiment, by opening a limit groove 22 at the front end of the swing plate 2, the limit groove 22 can penetrate the two end surfaces of the swing plate 2 along the width direction of the vehicle body 1, and penetrate the lower surface of the swing plate 2 downward, so that the entire front end surface of the swing plate 2 is an inverted step surface; when the hook plate 514 is clamped on the transition plate 9 through the fixing groove 515, the telescopic rod 52 continues to drive the fixing hook 51 to slide toward the rear end of the transition plate 9, so that the rear end of the transition plate 9 is embedded in the limit groove 22, and the front and rear ends of the transition plate 9 are clamped by the hook plate 514 and the swing plate 2 respectively, thereby improving the stability of the connection between the transition plate 9 and the fixing hook 51 and the swing plate 2.

[0032] Alternatively, if Figure 4 As shown, the fixed hook 51 includes a hook body 511 and an adjustment seat 512, the hook body 511 is rotatably connected to the adjustment seat 512 in a vertical plane, the long hole 513 is opened on the adjustment seat 512, the telescopic rod 52 is drivingly connected to the adjustment seat 512, and the hook plate 514 is connected to the hook body 511.

[0034] Alternatively, if Figure 1 As shown, the telescopic platform vehicle further includes a lifting rod 23, one end of which is hinged on the upper surface of the front end of the vehicle body 1, and the other end is hinged on the lower surface of the swing plate 2. The lifting rod 23 is used to extend and retract along its length direction.

[0035] In this embodiment, a lifting rod 23 is arranged between the front end of the vehicle body 1 and the swing plate 2, and the two ends of the lifting rod 23 are respectively hinged to the upper surface of the vehicle body 1 and the lower surface of the swing plate 2. When the lifting rod 23 is extended and retracted along its length direction, the swing plate 2 can be driven to rotate around the Y-axis relative to the inclined bracket 3, so that the fixed hook 51 can hook the transition plate 9.

[0036] Alternatively, if Figure 3As shown, the telescopic platform vehicle further includes a movable plate 61, which is rotatably connected to the rear end of the telescopic ladder 4 in a vertical plane, and the movable plate 61 is used to overlap on the ground.

[0037] In this embodiment, a movable plate 61 is provided at the rear end of the telescopic ladder 4. The movable plate 61 can rotate around the Y-axis relative to the telescopic ladder 4. When the telescopic ladder 4 slides in the negative direction of the X-axis and the negative direction of the Y-axis, the movable plate 61 rotates clockwise until it overlaps the ground. The movable plate 61 plays a transitional role between the telescopic ladder 4 and the ground. When a car passes through the movable plate 61 and drives towards the telescopic ladder 4, the climbing angle of the car gradually increases, which makes it easier for the car to drive onto the telescopic ladder 4. When not working, the movable plate 61 rotates counterclockwise until it is folded on the surface of the telescopic ladder 4 to save space.

[0043] In this embodiment, since the telescopic ladder 4 is located above the inclined bracket 3, the front end surface of the telescopic ladder 4 and the upper surface of the inclined bracket 3 will form a step structure. The step structure can be filled by providing a right-angled triangle bracket 41 at the front end of the telescopic ladder 4. Specifically, the two right-angled surfaces of the right-angled triangle bracket 41 are respectively connected to the upper surface of the inclined bracket 3 and the front end surface of the telescopic ladder 4, so that the inclined surface of the right-angled triangle bracket 41 faces upward and is connected with the upper surface of the inclined bracket 3 and the upper surface of the telescopic ladder 4 respectively, so that a smooth transition between the upper surface of the inclined bracket 3 and the upper surface of the telescopic ladder 4 can be achieved. Furthermore, when the car moves between the telescopic ladder 4, the inclined bracket 3 and the swing plate 2, it can be supported by the inclined surface of the right-angled triangle bracket 41, so that the car can run more smoothly and less damage to the platform car caused by the bumps of the car is caused.

Guide wheels 71 are provided on the upper surface, lower surface and side wall of the C-shaped groove. The guide wheels 71 on the upper surface, lower surface and side wall are in rolling contact with the telescopic ladder 4. When the telescopic ladder 4 slides relative to the inclined bracket 3, the guide wheels 71 on the upper surface and lower surface limit the telescopic ladder 4 in the Z-axis direction, and the guide wheels 71 on the side wall limit the telescopic ladder 4 in the Y-axis direction, so that the telescopic ladder 4 can slide relative to the inclined bracket 3 along its length direction.

[0046] Specifically, a plurality of sets of relative C-shaped guide mechanisms 7 may be provided at both ends of the tilt bracket 3 along the Y-axis direction, so that the telescopic ladder 4 can slide relative to the tilt bracket 3 along its length direction.
