Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0041] An embodiment of the present utility model provides a lifting platform for simulating the sea take-off and landing of an unmanned helicopter. Refer to Figures 1 to 4 , Figure 1 which is a schematic structural diagram of the lifting platform for simulating the sea take-off and landing of an unmanned helicopter. The lifting platform for simulating the sea take-off and landing of an unmanned helicopter includes: an upper table surface 1, a lower table surface 2, a first support frame 3, a second support frame 4, a first rotating assembly 5, a second rotating assembly 6, and a lifting mechanism 7;

[0042] Both the first support frame 3 and the second support frame 4 are arranged on the same side of the upper end surface of the lower table surface 2;

[0043] The lower end surface of the upper table surface 1 is connected to the top of the first support frame 3 through the first rotating assembly 5, and the second rotating assembly 6 is connected to the top of the second support frame 4. The upper table surface 1 is used for the unmanned helicopter;

[0044] The lifting mechanism 7 is arranged between the upper table surface 1 and the lower table surface 2 and is used to drive the upper table surface 1 to rotate around the first support frame 3 and the second support frame 4 to adjust the inclination of the upper table surface 1.

[0045] It should be noted that since the lifting mechanism 7 can drive the upper table surface 1 to rotate around the first support frame 3 and the second support frame 4, thereby adjusting the inclination of the upper table surface 1, that is, adjusting the head of the upper table surface 1 to be lower than the tail of the upper table surface 1 (as shown in Figure 2 ), or the head of the upper table surface 1 to be higher than the tail of the upper table surface 1 (as shown in Figure 3 ), the lifting mechanism 7 repeatedly drives the tail of the upper table surface 1 to rise and fall, and thus can simulate the undulating working conditions caused by sea waves.

[0046] It is worth noting that through the first support frame 3, the second support frame 4, and the lifting mechanism 7 of the present application, the support for the upper table surface 1 can be ensured.

[0047] It should also be noted that the second rotating assembly 6 is not shown in the figure.

[0048] In the embodiment of the present utility model, the first support frame 3 and the second support frame 4 are both arranged on the same side of the upper end surface of the lower table surface 2, and the lower end surface of the upper table surface 1 is connected to the top of the first support frame 3 through the first rotating assembly 5, and the second rotating assembly 6 is connected to the top of the second support frame 4. The upper table surface 1 is used for an unmanned helicopter, and the lifting mechanism 7 is arranged between the upper table surface 1 and the lower table surface 2 and drives the upper table surface 1 to rotate around the first support frame 3 and the second support frame 4 to adjust the inclination of the upper table surface 1. Through the above disclosed lifting platform for simulating the sea takeoff and landing of an unmanned helicopter, since the present application can repeatedly adjust the inclination angle of the upper table surface 1 through the lifting mechanism 7, therefore, the present application can simulate the undulating working conditions of a sea takeoff and landing platform.

[0049] Specifically, the first support frame 3 and / or the second support frame 4 are made of structural steel.

[0050] It should be noted that the first support frame 3 and the second support frame 4 can be made of structural steel or other materials (such as metal or non-metal materials), and those skilled in the art can select according to requirements.

[0051] Furthermore, both the first rotating assembly 5 and the second rotating assembly 6 include: a bearing seat, a bearing and a shaft;

[0052] The bearing is installed in the bearing seat;

[0053] One end of the shaft is fixed to the lower end surface of the upper table surface 1, and the other end of the shaft is arranged in the bearing hole of the bearing.

[0054] It should be noted that by installing the bearing in the bearing seat, fixing one end of the shaft to the lower end surface of the upper table surface 1, and arranging the other end of the shaft in the bearing hole of the bearing, the friction during the rotation of the upper table surface 1 can be reduced when the inclination of the upper table surface 1 is adjusted.

[0055] Specifically, the number of the lifting mechanisms 7 is multiple, and the multiple lifting mechanisms 7 are arranged on the other side of the upper end surface opposite to the first support frame 3 and the second support frame 4.

[0056] It should be noted that by setting the number of the lifting mechanisms 7 to be multiple and arranging the multiple lifting mechanisms 7 on the other side of the upper end surface opposite to the first support frame 3 and the second support frame 4, the upper table surface 1 can be driven to rotate simultaneously by the multiple lifting mechanisms 7 to adjust the inclination of the upper table surface 1.

[0057] Specifically, the lifting mechanism 7 is a thrust rod.

[0058] It should be noted that the lifting mechanism 7 can be a thrust rod or other lifting mechanisms 7 that can drive the upper table surface 1 to lift, and those skilled in the art can select according to requirements.

[0059] Further, the thrust rod can be any one of hydraulic type, electric push type, and pneumatic type.

[0060] It should be noted that the thrust rod can be of hydraulic type, can also be of electric push type, or can be of pneumatic type, and those skilled in the art can select according to requirements.

[0061] Specifically, the lifting platform for simulating the sea takeoff and landing of an unmanned helicopter further includes: a sliding assembly 8 and a limiting assembly;

[0062] The sliding assembly 8 is arranged on the upper end surface of the lower table surface 2;

[0063] The lower end of the thrust rod is arranged on the sliding assembly 8, and the upper end is hinged to the upper table surface 1;

[0064] The limiting assembly is used to limit the sliding of the sliding assembly 8 driving the thrust rod.

[0065] It should be noted that by setting the sliding assembly 8 and the limiting assembly, arranging the sliding assembly 8 on the upper end surface of the lower table surface 2, arranging the lower end of the thrust rod on the sliding assembly 8, hinging the upper end of the thrust rod to the upper table surface 1, and limiting the sliding of the sliding assembly 8 driving the thrust rod through the limiting assembly, the position of the lower end of the thrust rod can be adjusted through the sliding assembly 8, and further the inclination angle of the upper table surface 1 when the thrust rod shrinks to the shortest position and the inclination angle of the upper table surface 1 when the thrust rod extends to the longest can be adjusted to simulate different working conditions on different seas.

[0066] Specifically, the sliding assembly 8 includes: a first slider 81, a second slider 82, and a sliding shaft 83;

[0067] The first slider 81 and the second slider 82 are arranged in parallel;

[0068] A first sliding groove 811 is formed in the side of the first slider 81;

[0069] A second sliding groove 821 is formed in the side of the second slider 82;

[0070] The first end of the sliding shaft 83 is slidably arranged in the first sliding groove 811, and the second end is slidably arranged in the second sliding groove 821;

[0071] The limiting assembly is used to limit the sliding of the first end of the sliding shaft 83 in the first sliding groove 811 and limit the sliding of the second end of the sliding shaft 83 in the second sliding groove 821;

[0072] The lower end of the thrust rod is located between the first slider 81 and the second slider 82 and is connected to the sliding shaft 83.

[0073] It should be noted that the first slider 81 and the second slider 82 are arranged in parallel. A first sliding groove 811 is formed in the side of the first slider 81, and a second sliding groove 821 is formed in the side of the second slider 82. The first end of the sliding shaft 83 is slidably arranged in the first sliding groove 811, and the second end is slidably arranged in the second sliding groove 821. The limiting component restricts the first end of the sliding shaft 83 from sliding in the first sliding groove 811 and restricts the second end of the sliding shaft 83 from sliding in the second sliding groove 821. The lower end of the thrust rod is located between the first slider 81 and the second slider 82 and is connected to the sliding shaft 83. Through the above solution, not only can the sliding shaft 83 be prevented from disengaging from the first sliding groove 811 and the second sliding groove 821, but when it is necessary to move the lower end position of the thrust rod, the restrictions on both ends of the sliding shaft 83 can be released by the limiting component, so that the lower end of the thrust rod moves. After the thrust rod moves to the target position, the sliding shaft 83 is limited by the limiting component, so that the lower end of the thrust rod is fixed. Furthermore, when the thrust rod expands and contracts, the inclination angle of the corresponding upper table 1 is changed to simulate different sea wave conditions.

[0074] Specifically, the limiting component further includes: a first limiting pin 91 and a second limiting pin 92;

[0075] A plurality of first through holes 812 for inserting the first limiting pin 91 are formed in the top of the first slider 81 along the length direction. Among them, the first through holes 812 are communicated with the first sliding groove 811;

[0076] A plurality of second through holes 822 for inserting the second limiting pin 92 are formed in the top of the second slider 82 along the length direction. Among them, the second through holes 822 are communicated with the second sliding groove 821;

[0077] A first mating hole for mating with the first limiting pin 91 is formed at the first end of the sliding shaft 83, and a second mating hole for mating with the second limiting pin 92 is formed at the second end.

[0078] It should be noted that a plurality of first through holes 812 for inserting the first limit pin 91 are formed in the top of the first slider 81 along the length direction. Among them, the first through holes 812 communicate with the first chute 811. And a plurality of second through holes 822 for inserting the second limit pin 92 are formed in the top of the second slider 82 along the length direction. Among them, the second through holes 822 communicate with the second chute 821. In addition, a first mating hole cooperating with the first limit pin 91 is formed at the first end of the sliding shaft 83, and a second mating hole cooperating with the second limit pin 92 is formed at the second end. Since the first through holes 812 communicate with the first chute 811, and the second through holes 822 communicate with the second chute 821, therefore, when the first limit pin 91 is inserted from the first through holes 812, if the first through holes 812 are aligned with the first mating hole at the first end of the sliding shaft 83 at this time, the first limit pin 91 can be inserted into the first mating hole. And when the second limit pin 92 is inserted from the second through holes 822, if the second through holes 822 are aligned with the second mating hole at the second end of the sliding shaft 83 at this time, the second limit pin 92 can be inserted into the second mating hole, thereby preventing the sliding shaft 83 from sliding in the first chute 811 and the second chute 821.

[0079] It should be noted that in order to ensure that the first limit pin 91 can quickly pass through the first through holes 812 and be inserted into the first mating hole, and the second limit pin 92 can quickly pass through the second through holes 822 and be inserted into the second mating hole, generally, the diameter of the first mating hole is set to be larger than that of the first through holes 812, and generally, the diameter of the second mating hole is set to be larger than that of the second through holes 822.

[0080] Further, a plurality of first through holes 812 are formed in the top of the first slider 81 at a preset interval;

[0081] A plurality of second through holes 822 are formed in the top of the second slider 82 at a preset interval.

[0082] It should be noted that a plurality of first through holes 812 are formed in the top of the first slider 81 at a preset interval, and a plurality of second through holes 822 are formed in the top of the second slider 82 at a preset interval, enabling the staff to move the position of the sliding shaft 83 in the first chute 811 and the second chute 821 according to requirements, thereby facilitating the staff to adjust the lower end position of the thrust rod.

[0083] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention.
