[0025] Example 1

[0026] Reference Figures 1-6 This is the first embodiment of the present invention. This embodiment provides an automatic lifting frame for assault boats. The automatic lifting frame for assault boats includes a support component 100 and a tilting component 200. The two components work together to facilitate the loading and unloading of assault boats.

[0027] The support assembly 100 includes a fixed plate 101, a telescopic frame 102, a fixed frame 103, and a telescopic component 104. The telescopic frame 102 is disposed on the top of the fixed plate 101, the fixed frame 103 is fixed to the top of the telescopic frame 102, and the telescopic component 104 is located inside the telescopic frame 102.

[0028] The fixed plate 101 is fixed to the top of the carriage with screws. The telescopic frame 102 is a telescopic frame. The fixed frame 103 is fixed to the telescopic end of the telescopic frame 102. The fixed frame 103 is used to place the assault boat and tie the assault boat to the fixed frame 103 to prevent the assault boat from falling during transportation. The telescopic component 104 is used to drive the telescopic frame 102 to extend and retract, so that the telescopic frame 102 can drive the fixed frame 103 and the assault boat to move.

[0029] The flipping assembly 200 is mounted on the support assembly 100 and includes a movable component 201, a rotating frame 202, a rotating plate 203, a positioning plate 204, a protrusion 205, and a connecting plate 206. The movable component 201 is rotatably connected to one side of the fixed plate 101, the rotating frame 202 is rotatably connected to one side of the fixed plate 101, the rotating plate 203 is rotatably connected to one side of the fixed plate 101, the positioning plate 204 is fixed to one side of the rotating frame 202, one side of the protrusion 205 is fixed to the positioning plate 204, and the connecting plate 206 is fixed to one side of the telescopic frame 102.

[0030] The movable component 201 is used to drive the telescopic frame 102 to move horizontally, thereby enabling the telescopic frame 102 to move the assault boat on the top of the vehicle, thus facilitating the loading and unloading of the assault boat. The rotating plate 203 is rotatably connected to the fixed plate 101 via a rotating shaft, and the rotating plate 203 is slidably connected to the telescopic frame 102 via a pulley and a sliding groove. The upper part of the positioning plate 204 is connected to the telescopic frame 102 via a pulley and a sliding groove. The connecting plate 206 is higher on one side near the end of the telescopic frame 102 and lower on the other side. When the telescopic frame 102 moves a certain distance, it will drive the connecting plate 206 to contact the positioning plate 204, and the protrusion 205 will contact the transition groove Z. At this time, the protrusion 205 will move upward along the transition groove Z, driving the positioning plate 204 and the rotating frame 202 to move upward. When the positioning plate 204 gradually rotates upward, it will cause the protrusion 205 to engage with the slot X. At this time, the positioning plate 204 and the connecting plate 206 can be connected by the cooperation of the two. During continuous movement, the telescopic frame 102, through the cooperation of the connecting plate 206 and the positioning plate 204, drives the rotating frame 202 to rotate upward. The rotating frame 202 rotates the side of the telescopic frame 102 located on the top of the carriage upward, thereby allowing the telescopic frame 102 to flip over. This allows the telescopic frame 102 to rotate the side of the fixed frame 103 to the ground, enabling the loading and unloading of the assault boat. When the assault boat is loaded and needs to be placed on the top of the carriage, the moving part 201 drives the telescopic frame 102 to move upward at an inclined angle. During the movement, the telescopic frame 102 drives the rotating frame 202 to rotate downward, gradually rotating the rotating frame 202 to a horizontal state. At the same time, as the telescopic frame 102 continues to move, the protrusion 205 separates from the slot X and moves downward along the transition groove Z until it separates from the transition groove Z. At this point, the telescopic frame 102 can continue to move to the initial position.

[0031] Example 2

[0032] Reference Figures 1-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0033] Specifically, the connecting plate 206 has a transition groove Z corresponding to the protrusion 205, and the connecting plate 206 has a slot X, which engages with the protrusion 205.

[0034] Specifically, the telescopic component 104 includes a first motor 104a, a sprocket 104b, a chain 104c, and a connecting frame 104d. The first motor 104a is located inside the telescopic frame 102, the sprocket 104b is located inside the telescopic frame 102, the chain 104c is located outside the sprocket 104b, and the connecting frame 104d is fixed inside the telescopic frame 102.

[0035] A mounting bracket is provided on the fixed plate 101. The first motor 104a, sprocket 104b, and chain 104c are all mounted on the mounting bracket. There are two sprockets 104b, one located at the end of the mounting bracket and the other fixed to the output shaft of the first motor 104a. The center of the connecting bracket 104d is connected to the chain 104c, and both ends are fixed to the inner wall of the telescopic frame 102. The two sprockets 104b are connected by the chain 104c. When the first motor 104a drives the sprocket 104b to rotate, the sprocket 104b can drive the chain 104c to move, thereby enabling the chain 104c to drive the connecting bracket 104d to move, and thus enabling the connecting bracket 104d to drive the telescopic frame 102 to extend and retract.

[0036] Specifically, the moving part 201 includes a second motor 201a, a gear 201b, and a rack 201c. The second motor 201a is disposed inside the fixed plate 101, the gear 201b is fixed to the output end of the second motor 201a, and the rack 201c is fixed to the bottom of the telescopic frame 102.

[0037] Gear 201b meshes with rack 201c. When the second motor 201a drives gear 201b to rotate, it can drive rack 201c to move, thereby enabling the rack 201c telescopic frame 102 to move as a whole.

[0038] Example 3

[0039] Reference Figures 1-6 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0040] Specifically, the support assembly 100 also includes a telescopic rod 105, which is mounted on the fixed plate 101.

[0041] There are four telescopic rods 105, arranged in two groups on both sides of the fixed plate 101. One of the two telescopic rods 105 on one side of the fixed plate 101 is rotatably connected at one end to the fixed plate 101 and at the other end to the rotating plate 203. The other telescopic rod 105 is rotatably connected at one end to the fixed plate 101 and at the other end to the rotating frame 202. The two work together to support the telescopic frame 102 when it rotates, preventing it from shifting during rotation.

[0042] Specifically, the support assembly 100 also includes a buffer 106, which is disposed on one side of the fixing plate 101.

[0043] When the telescopic frame 102 is equipped with an assault boat, and the telescopic frame 102 gradually rotates to a horizontal position on the top of the carriage, it can be buffered by the buffer 106 to avoid vibration when the telescopic frame 102 is placed horizontally.

[0044] Specifically, the support assembly 100 also includes a support frame 107, which is located on one side of the fixed plate 101.

[0045] The support frame 107 is fixed to the top of the carriage with bolts. When the telescopic frame 102 is in a horizontal state, it is supported by the support frame 107 to prevent the telescopic frame 102 from shaking. The telescopic frame 102 is connected to the support frame 107 through the cooperation of pulleys and slides.

[0046] When loading the assault boat, the mounting bracket 103 is located on top of the vehicle. First, the mounting bracket 103 needs to be lowered. Then, the second motor 201a is started, driving the gear 201b to rotate. This gear 201b then moves the rack 201c, causing the rack 201c and telescopic frame 102 to move as a whole. After the telescopic frame 102 has moved a certain distance, it will cause the connecting plate 206 to contact the positioning plate 204, and the protrusion 205 to contact the transition groove Z. The protrusion 205 will then move upwards along the transition groove Z, causing the positioning plate 204 and the rotating frame 202 to move upwards. As the positioning plate 204 gradually rotates upwards, the protrusion 205 will engage with the slot X. Through this interaction, the positioning plate 204 and the connecting plate can be connected. Connect 206. During continuous movement, the telescopic frame 102 will rotate upward through the cooperation of the connecting plate 206 and the positioning plate 204. The rotating frame 202 will rotate the side of the telescopic frame 102 located on the top of the carriage upward, thereby allowing the telescopic frame 102 to flip. This will allow the telescopic frame 102 to rotate the fixed frame 103 to the ground. At the same time, the first motor 104a will be started to drive the sprocket 104b to rotate. The sprocket 104b will drive the chain 104c to move, which will drive the connecting frame 104d to move. This will allow the connecting frame 104d to drive the telescopic frame 102 to extend outward, thereby bringing the fixed frame 103 closer to the ground. Then, the assault boat will be placed on top of the fixed frame 103 and secured.

[0047] Once the inflatable boat is secured and placed on top of the vehicle, the second motor 201a is restarted to drive the gear 201b to rotate. This gear 201b then drives the rack 201c to move, which in turn moves the entire telescopic frame 102. During this movement, the telescopic frame 102 causes the rotating frame 202 to rotate downwards, gradually reaching a horizontal position. Simultaneously, as the telescopic frame 102 continues to move, the protrusion 205 separates from the slot X and moves downwards along the transition groove Z until it separates from the transition groove Z. At this point, the telescopic frame 102 can continue to move to its initial position. At the same time, the first motor 104a is started to drive the sprocket 104b to rotate. This sprocket 104b drives the chain 104c to move, which in turn moves the connecting frame 104d. This causes the connecting frame 104d to retract the telescopic frame 102 until it enters the support frame 107.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
