The outer wall of the barrel 205 is provided with a guide strip-shaped protrusion, and the guide strip-shaped protrusion is clamped in a clamping groove on the inner wall of the guide sleeve 201 to slide, and the barrel 205 can only slide but cannot rotate.

The first buffer spring 210 can isolate the ceiling driving system and the telescopic rod group 2, when the screw rod 202 rotates, the screw 204 ascends along the guide sleeve 201 and jacks up the sleeve 205, the sleeve 205 extrudes the first buffer spring 210, the upper end of the first buffer spring 210 extrudes the telescopic rod group 2 and forces the telescopic rod group 2 to ascend, when the pleasure boat is fluctuated along with waves, the suddenly increased or suddenly decreased acting force between the hull and the ceiling is buffered by the first buffer spring 210, and the damage of sudden change of the acceleration in the vertical direction to the ceiling driving system is effectively improved.

When the ceiling device receives horizontal wind force, traditional guide arm or lifter rubs with the guide pin bushing, leads to one or more frictional resistance increase therein, even be equipped with the ball in the uide bushing 201, if the lifter adopts the structure of independent drive formula, the lifter that frictional resistance increases moves slowly, and smooth and easy lifter removes soon, because the general four corners of yacht ceiling sets up the lifter, and the span is great, and the arm length, easily breaks curved lifter or ceiling skeleton, leads to the card to the later repair degree of difficulty is big. The first buffer spring 210 can store driving force for a short time, but when the spring is fully compressed, the driving system still directly acts on some lifting rods to cause bending of the structural members similar to the case of unbalanced load.

Because the four lifter assemblies are driven simultaneously with a single drive, once a lifter assembly is clamped and the first buffer spring 210 is compressed to its limit, the transverse drive shaft 405 and transfer case 4 are clamped, and there is no additional pushing force on the other lifters in addition to the spring retention force, so the four lifters are in balance. When short-term gusts come, a part of rising driving force can be stored by virtue of the buffering of the first buffer spring 210, at the moment, the ceiling device is lifted intermittently, when long gusts come, the driving device is blocked, and the four lifting rods are kept still, so that the structure construction is prevented from being broken.

The ceiling lifting driving motor 407 may be a servo motor, and may set a maximum torque, or may be provided with a torque sensor, and may stop driving when the motor exceeds the maximum set torque when the telescopic rod group 2 is locked, thereby preventing the continuous output of torque to the telescopic rod group 2. Or reversely rotating, descending for a designated height, and then continuing to rotate forward until the target height is reached; namely, the device is reversely rotated to repair or reduce the clamping phenomenon; if the repeated self-adjustment is still stuck, for example, the reverse self-adjustment is performed 3 times, and the amplitude of each reverse adjustment is increased a little (similar to a hill-break), then the manual handling of the fault is prompted.

The intermittent lifting effect can meet daily needs for common yachts, but if gusts occur, the ceiling is intermittently lifted or suspended, so that experience of tourists is definitely greatly reduced.

Therefore, in a preferred solution, the telescopic rod set 2 includes at least three fan-shaped rod pieces 207, the end portions of the fan-shaped rod pieces 207 are sequentially connected to form a cylindrical structure, at least three fan-shaped sliding pieces 206 are further disposed in the sleeve 205, the end portions of the fan-shaped sliding pieces 206 are sequentially connected to form a cylindrical structure, the sleeve 205 and the fan-shaped sliding pieces 206 are slidably connected, one end of each fan-shaped sliding piece 206 is connected to each fan-shaped rod piece 207, the first buffer springs 210 are multiple, two ends of each first buffer spring 210 respectively abut against the sleeve 205 and each fan-shaped sliding piece 206, a conical head 211 is disposed at the upper end of each fan-shaped rod piece 207, a top connecting sleeve 208 is further disposed, the top connecting sleeve 208 is connected to the skeleton frame 102, a plurality of conical holes 212 are disposed in the top connecting sleeve 208, each conical head 211 is sleeved with each conical hole 212, and a counter bore portion 214 is disposed at one end of the top connecting sleeve 208 close to the skeleton frame 102.

The extended side plates 101 are preferably turned over and retracted when the ceiling is lifted, so that the transverse wind resistance is reduced. When the transverse gust occurs, the transverse acting force is transmitted to the telescopic rod group 2 through the ceiling device, the friction force between the telescopic rod group 2 and the guide sleeve 201 is increased, and since the telescopic rod group 2 is composed of three independently lifting fan-shaped rod pieces 207, even if the abutting position of the two fan-shaped rod pieces 207 is too tightly contacted with the guide sleeve 201, that is, the friction force between the two fan-shaped rod pieces 207 and the inner wall of the guide sleeve 201 is increased, at least one fan-shaped rod piece 207 can be ensured to be in a smooth state, at the moment, the sleeve 205 is driven by the ceiling driving system to continuously lift, and since the fan-shaped slide piece 206 is connected with the sleeve 205 through the first buffer spring 210, the two fan-shaped slide pieces 206 are fixed, the first buffer spring 210 is compressed, and the other fan-shaped slide piece 206 is pushed by the first buffer spring 210 to continuously lift. The conical head 211 at the upper end of the fan-shaped rod piece 207 pushes against the conical hole 212, so that the top end connecting sleeve 208 rises, and as the top end connecting sleeve 208 is connected with the fan-shaped rod piece 207 by adopting a conical surface, the other two conical holes 212 are easily separated from the other two conical heads 211, and at the moment of separation, the force of the ceiling device on the fan-shaped rod piece 207 which is clamped originally is eliminated, the force on the fan-shaped rod piece 207 which is smooth originally is suddenly increased, and the fan-shaped rod piece 207 is possibly clamped. However, since the other two fan-shaped pole pieces 207 are in a smooth state, under the action of the acting force of the first buffer spring 210 in the lowered compressed state and the continuous driving force driven by the driving system, the two fan-shaped pole pieces 207 jack the top connecting sleeve 208 through the conical head 211 again, so that the ceiling device continues to rise, and the other conical head 211 is separated from the conical hole 212, and the cycle is alternated, so that the continuous rising of the ceiling device is ensured.

In the preferred scheme, a plurality of limit nails 213 are arranged in the counter bore section 214, each limit nail 213 is connected with the cone head 211, and a gap is arranged between the nail cap of the limit nail 213 and the bottom end of the counter bore section 214.

The upper end of the limiting nail 213 is provided with a big head end, when the conical head 211 is separated from the conical hole 212 by a certain height, the big head end is limited by the big head end, and the depth of the big head end from the bottommost end of the counter bore portion 214 is smaller than the length of the conical head 211, so that the top connecting sleeve 208 cannot be completely separated from the conical head 211, and the whole ceiling 1 is prevented from being lifted and blown away by wind.

In the preferred scheme, telescopic link group 2 is hollow structure, and lead screw 202 lower extreme is connected with the hull, and the lead screw 202 upper end is equipped with the smooth support 209, and smooth support 209 outer wall and telescopic link group 2 inner wall sliding connection.
