Background Art

[0002] Cabins or vans can be used for field operations and combat. They are special equipment used in geological exploration, communication engineering, water conservancy engineering, construction engineering and military fields. The equipment or instruments installed in the cabin or van sometimes need to be pulled out of the cabin for operation. It is necessary to set a retractable platform on one side of the cabin or van to support the equipment or instruments operating outside the cabin. However, the volume of such an outside cabin operation platform after storage is large, occupying precious cabin space. In addition, although the existing boarding ladder can be folded and stored in the cabin, it also has the problem of occupying a large space in the cabin, and it cannot be used as a workbench outside the vehicle except for boarding. Summary of the invention

[0003] In order to overcome the defect that the working platform or the boarding ladder of the existing square cabin or van occupies a large volume of the cabin space after being stored, the present invention provides a vehicle flip ladder platform to reduce the cabin space occupied by the ladder platform.

[0004] The present invention is achieved through the following technical solutions:

[0005] A vehicle flip step platform comprises an upper pedal, a lower pedal, and a limit rod assembly, a gas spring, a connecting rod and a storage locking device arranged in pairs, wherein one corner at both ends of the upper pedal is hinged to the upper ends of the vertical rear sides of the straight rods on both sides of the vehicle side compartment frame through a hinge seat, and the hinge rods at one corner at both ends of the lower pedal are hinged to the lower ends of the vertical inner sides of the straight rods on both sides of the vehicle side compartment frame; one end of the inclined gas spring is hinged to the middle parts of the two ends of the upper pedal, and the other end of the gas spring is hinged to the other corners at the two ends of the lower pedal; one end of the limit rod assembly is hinged to the middle parts of the two ends of the upper pedal close to the hinge seat, and the other end of the limit rod assembly is hinged to the middle parts of the two ends of the lower pedal; one end of the connecting rod is hinged to a corner at both ends of the upper pedal away from the hinge seat, and the other end of the connecting rod is hinged to the middle parts of the two ends of the lower pedal, and the hinge point of the other end of the connecting rod is adjacent to the hinge point of the other end of the limit rod; the storage locking device is respectively arranged on the two vertical inner sides of the vehicle side compartment frame and at both ends of the lower pedal away from the hinge rod.

[0006] The purpose of the present invention can be further achieved by the following technical measures.

[0007] Furthermore, the limit rod assembly includes an upper limit rod and a lower limit rod hinged at adjacent ends, one end of the upper limit rod is hinged to the middle of both ends of the upper pedal near the hinge seat, and one end of the lower limit rod is hinged to the middle of both ends of the lower pedal.

[0008] Furthermore, the connecting rod is L-shaped, and the long side ends of the L-shape are respectively hinged to a corner of the upper pedal away from the hinge seat, and the short side ends of the L-shape are respectively hinged to the middle of the two ends of the lower pedal, and the hinge point is adjacent to the hinge point of the other end of the limit rod combination.

[0009] Furthermore, the storage locking device includes a locking block and a locking strip, the locking block includes a mounting plate and a locking column, one end of the mounting plate is vertically fixedly connected to one end of the locking column, and a V-shaped groove matching the locking column is opened in the middle of the locking strip; the other end of the mounting plate is respectively fixed to the upper part of the vertical inner side surface of the straight rods on both sides of the vehicle side compartment frame, and the locking strips are respectively fixed to a corner of the end surface of the lower pedal away from the hinge rod; when the vehicle flip step ladder platform is stored and locked in the vehicle side compartment frame, the other end of the locking column is respectively embedded in the V-shaped groove corresponding to the lower pedal.

[0010] Furthermore, both the upper pedal and the lower pedal are structures that cover the upper side of a rectangular frame with a patterned steel plate, the width C of the lower pedal is greater than the width B of the upper pedal, the side compartment cover is fixed on the lower side of the rectangular frame of the lower pedal, and the buckle lock is set on the center of one side of the side compartment cover away from the hinged rod.

[0011] The present invention forms a four-bar hinge mechanism between the upper and lower pedals through a limit rod combination and a connecting rod. The two ends of the upper and lower pedals can be respectively rotated 90° clockwise around their corresponding hinge seats and hinge rods to unfold into a horizontal use state separated from each other. At this time, the limit rod combination and the connecting rod are supported in a triangle between the upper and lower pedals, ensuring the stability of the upper and lower pedals when unfolded. The upper and lower pedals can also be rotated 90° counterclockwise around their respective hinge seats and hinge centers of the hinge rods by the elastic force of the gas spring reset to be stored in the vehicle side compartment, making the closing of the vehicle side compartment more labor-saving; at the same time, the elastic force provided by the gas spring also keeps the upper and lower pedals in a superimposed state against each other, so that the thickness of the superimposed upper and lower pedals when stored is smaller. The present invention has a compact structure, is labor-saving and convenient to use. In addition to being convenient for people to board the vehicle, the upper pedal can also be used as an external workbench, which expands the scope of use and improves work efficiency.

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] like Figure 1 to Figure 4 As shown, the present invention comprises an upper pedal 1, a lower pedal 2, and a limit rod assembly 3, a gas spring 4, a connecting rod 5 and a storage locking device 6 arranged in pairs. The two ends of the upper pedal 1 and the two ends of the lower pedal 2 of the present invention are respectively Figure 1 The left and right ends of the upper pedal 1 and the left and right ends of the lower pedal 2. Figure 2 The left corners of the middle upper pedal 1 are respectively hinged to the upper ends of the vertical rear sides of the straight rods 101 on both sides of the vehicle side compartment frame through the hinge seats 7, and the hinge rods 21 at the left corners of the lower pedal 2 are respectively hinged to the lower ends of the vertical inner sides of the straight rods 101 on both sides of the vehicle side compartment frame. Figure 2 The upper pedal 1 at the middle upper side is hinged at both ends, and the lower ends of the gas springs 4 are respectively connected to Figure 2 The lower left corners of the two ends of the lower pedal 2 at the lower side are hinged. The gas spring 4 assists the vertical stacking of the upper pedal 1 and the lower pedal 2, thereby making it easier to close the vehicle side compartment.

[0019] Figure 2 The limit rod assembly 3 in the embodiment includes an upper limit rod 31 and a lower limit rod 32 which are hinged at adjacent ends. The upper end of the upper limit rod 31 is hinged to the middle of both ends of the upper pedal 1 near the hinge seat 7, and the lower end of the lower limit rod 32 is hinged to the middle of both ends of the lower pedal 2. Figure 4 As shown, when the limit rod assembly 3 with a central hinged structure is stored in the side compartment of the vehicle, the upper limit rod 31 and the lower limit rod 32 are rotated nearly 180° around the hinge and overlap each other, so that the thickness of the upper and lower pedals after storage is smaller and the space occupied by the vehicle is smaller.

[0020] like Figure 4 As shown, the connecting rod 5 is L-shaped, and the ends of the long sides 51 of the L-shaped are respectively hinged to a corner of the upper pedal 1 away from the hinge seat 7 at both ends, and the ends of the short sides 52 of the L-shaped are respectively hinged to the middle of the two ends of the lower pedal 2. Figure 2 As shown, the hinge point is Figure 2 The hinge points at the lower ends of the middle limit rod assembly 3 are adjacent to each other and are located on the right side of the hinge point at the lower ends of the limit rod assembly 3 .

[0021] like Figure 2 and Figure 3As shown, the storage locking device 6 includes a locking block 61 and a locking strip 62. The locking block 61 includes a mounting plate 611 and a locking column 612. One end of the mounting plate 611 is vertically fixedly connected to one end of the locking column 612. A V-shaped groove 621 matching the locking column 611 is opened in the middle of the locking strip 62. The other end of the mounting plate 611 is respectively fixed to the upper part of the vertical inner side surface of the straight rod 101 on both sides of the vehicle side compartment frame, and the locking strip 62 is respectively fixed to a corner of the end surface of the lower pedal 2 away from the hinge rod 21. When the vehicle flip step ladder platform is stored and locked in the vehicle side compartment frame, the other end of the locking column 611 is respectively embedded in the V-shaped groove 621 corresponding to the locking strip 62 at the upper end of the lower pedal 2, thereby improving the reliability of the locking state of the present invention.

[0022] like Figure 1 and Figure 2 As shown, both the upper pedal 1 and the lower pedal 2 are structures in which the upper side of the rectangular frame 11 is covered with a patterned steel plate 111, the width C of the lower pedal is greater than the width B of the upper pedal, the side hatch cover 22 is fixed on the lower side of the rectangular frame 11 of the lower pedal 2, and the buckle lock 8 is arranged on the center of one side of the side hatch cover 22 away from the hinge rod 21. The width of the upper pedal 1 of the present invention is much greater than the width of the general boarding ladder pedal, and can be used as a workbench in addition to boarding.

[0023] like Figure 2 and Figure 4 As shown, when the present invention needs to be opened, press the hand lock 8 on the side cabin cover 22 and pull the lower pedal 2 outward. Under the combined effect of the pulling force of the operator and the gravity of the present invention, the upper pedal 1 and the lower pedal 2 overcome the elastic force of the gas spring 4, and rotate clockwise around the center of the hinge seat 7 and the center of the hinge rod 21 to unfold into a horizontal use state separated from each other. The limit rod combination 3 and the connecting rod 5 are supported in a triangle between the upper pedal 1 and the lower pedal 2, ensuring the stability of the upper pedal 1 and the lower pedal 2 when unfolded, which is convenient for people to get on the vehicle and for pulling the equipment in the cabin or van onto the upper pedal 1.

[0024] When the present invention needs to be closed, the lower pedal 2 is pushed upward, and the upper pedal 1 and the lower pedal 2 rotate counterclockwise around the center of the hinge seat 7 and the center of the hinge rod 21 respectively under the help of the restoring force of the gas spring 4, and the upper limit rod 31 and the lower limit rod 32 rotate around the center of the hinge and overlap each other. At this time, the other ends of the locking columns 611 on the straight rods 101 on both sides of the vehicle side compartment 10 are respectively embedded in the V-shaped grooves 621 corresponding to the locking strips 62 on the upper end of the lower pedal 2, thereby locking the present invention. At the same time, the latch of the hand lock 8 buckles the upper side of the vehicle side compartment 10, thereby locking the present invention in the vehicle side compartment 10.

[0025] 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.
