[0032] The utility model is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Combination Figures 1-9 This embodiment discloses an automatic lifting boat awning, which is easy to operate in extending, propping up, and folding and storing, and has a compact driving structure.

[0034] Specifically, the automatic lifting awning includes a bracket 1, a awning cloth 3, a mounting seat 2, a driving member 4, a supporting member 5 and a positioning member 6.

[0035] Among them, the bracket 1 is composed of three "n"-shaped support frames, and the tops of the support frames are connected to the same tarpaulin 3 to form a flip linkage mechanism, that is, when one of the support frames performs a flipping activity, with the help of the pulling effect of the tarpaulin 3, the remaining support frames will also perform a flipping activity.

[0036] Furthermore, combined with Figure 2 As shown, the bracket 1 includes a first support frame 11, a second support frame 12 and a third support frame 13. The bottom of the first support frame 11 and the second support frame 12 are hinged to the mounting seat 2, and after extension, they form a "V"-shaped frame; the bottom of the third support frame 13 is hinged to the middle of the second support frame 12, and after extension, it forms a "y"-shaped frame with the second support frame 12. The three are in an "n"-shaped structure as a whole, which enhances the stability and bearing capacity of the structure.

[0037] A mounting seat 2 is provided below the bracket 1, and the bottom of the bracket 1 is hinged to the top of the mounting groove 23. The hinged connection enables the upper bracket 1 to be stably flipped and folded to one side of the hull a after being flipped and stored.

[0038] Further, such as Figure 3 As shown, the bottom of the mounting seat 2 is connected to the side b of the hull a, and the bottom of the mounting seat 2 is provided with an abutting portion 21 that abuts against the side b. The abutting portion 21 forms an "n"-shaped notch at the bottom, and the notch faces the metal square tube of the side b. The notch is tightly fitted to the side b through an appropriate width to ensure stable contact between the bottom of the mounting seat 2 and the side b. In addition, during installation, the notch can slide flexibly along the top path of the side b, which is convenient for flexible adjustment of its installation position. The connection between the mounting seat 2 and the side b is achieved by installing screws c. The installing screws c are specifically self-locking screws, which are first driven in from the bottom of the side b, pass through the entire side b and are inserted into the mounting seat 2 to achieve a fixed connection. In actual application, this is easy to operate and has a flexible installation position.

[0039] refer to Figure 4 and 5, a driving member 4 is provided at the bottom of the hinge between the mounting base 2 and the bracket 1. The driving member 4 is located inside the mounting base 2 and includes an integrated motor 43, a lead screw 44 transmission assembly, a rack 41, and a gear 42, and can drive the bracket 1 to automatically turn over. Specifically, vertical side plates 22 are provided on the left and right sides of the top of the mounting base 2, and an installation groove 23 for accommodating the driving member 4 is formed between the side plates 22. A circular inner cavity is provided directly below the mounting base 2 in the installation groove 23. The motor 43 is installed in the circular inner cavity. A T-shaped groove 411 is provided on one side of the rack 41 close to the motor 43. A nut 45 is movably clamped inside the T-shaped groove 411. The nut 45 is meshed with the lead screw 44 to form the lead screw 44 transmission assembly. A plug-in groove 412 is provided at the bottom of the rack 41, and a plug-in member 46 is detachably provided in the plug-in groove 412. The bottom of the plug-in member 46 is movably connected to the inner side wall of the circular inner cavity, which is convenient for maintaining and replacing components.

[0040] Further, in order to enhance the stability of the rack 41 during installation, a plug-in groove 412 is provided at the bottom of the rack 41, and a plug-in member 46 is detachably connected in the plug-in groove 412. The bottom of the plug-in member 46 is a horizontal abutting and sliding end face. In this embodiment, the plug-in member 46 is made of hard plastic. The top of the plug-in member 46 is inserted into the plug-in groove 412, and the bottom of the plug-in member 46 is partially exposed outside the bottom of the rack 41, forming an extended abutting structure at the bottom of the rack 41. During use, the bottom of the plug-in member 46 contacts the external structure (the bottom of the circular inner cavity). First, it can have better smoothness after friction of the plastic itself to improve the sliding smoothness. Second, it can be used as a wear part, and after long-term use, it can reduce costs for component replacement and maintenance. Third, using plastic as the abutting structure is beneficial to preventing the rack 41 from having excessive rigid contact with the external structure during lateral movement, improving the sound insulation and protecting the structure effect.

[0041] Further, the output end of the motor 43 is connected with a reducer, and an outer bushing is provided on the reducer. The bottom of the outer bushing is fixedly connected to the installation groove 23 through bolts.

[0042] The working principle of the driving member 4 is: the motor 43 drives the rack 41 to reciprocate horizontally through the lead screw 44 transmission assembly. The rack 41 is meshed with the gear 42 (the bottom of the gear 42 passes through the through hole at the bottom of the installation groove 23 and enters the top of the circular inner cavity inside the mounting base 2 and forms a meshing connection structure with the rack 41). The axial center line of the gear 42 is hinged to the mounting base 2 through a rotating shaft, thereby driving the first support frame 11 to turn over, and then driving the second support frame 12 and the third support frame 13 to turn over. When the rack 41 moves away from the motor 43, the bracket 1 turns outwards to unfold the tarpaulin 3; when the rack 41 moves close to the motor 43, the bracket 1 turns inwards to store the tarpaulin 3.

[0043] Combined with Figure 1 and Figure 6, a supporting member 5 and a positioning member 6 corresponding to the downward turning position of the bracket 1 are provided on the ship's side b. The supporting member 5 is located at the top of the ship's side b, and a supporting groove for accommodating the bracket 1 is provided at the top, which is used to support the bracket 1 after being stored. As Figure 9 shown, the side view profile of the supporting member 5 is in an "H" shape structure. A buffer structure is provided in the supporting groove at the top to reduce the impact and noise when the bracket 1 is stored. The buffer structure is specifically a buffer pad 53. A first locking hole 51 is provided at the bottom of the supporting groove, and a second locking hole 52 is provided on the side wall of the supporting member 5. The first locking hole 51 and the second locking hole 52 are used to install self-locking screws to fix it on the ship's side b.

[0044] In addition, as shown in Figure 2 , a leg 15 corresponding to the positioning member 6 is provided on the bracket 1. It should be noted that 2 connecting seats 14 are installed in the middle of the second support frame 12. The 2 connecting seats 14 are arranged vertically in alignment. The side view profile of the connecting seat 14 is in an "H" shape structure. A perforation is provided on the side of the connecting seat 14 and is connected and fixed to the side wall of the second support frame 12 by bolts. A third support frame 13 is pivotally connected to the upper connecting seat 14. The height of the third support frame 13 is less than the heights of the first support frame 11 and the second support frame 12. The third support frame 13 is in an "n" shape structure located above the second support frame 12 and forms a "y" shape frame with the second support frame 12 after extension, further improving the support strength and stability. A leg 15 is connected to the bottom of the lower connecting seat 14, and the leg 15 is located below the second support frame 12. In the folded and stored state, the bottom of the leg 15 can abut against the hull a to form a support structure for the bracket 1, which is convenient for storage and fixation. The middle of the bottom of the leg 15 is a counterbore structure. After the bracket 1 is turned down and stored, the two legs 15 can form a clamping and limiting structure with the positioning member 6 to ensure that the bracket 1 is stable and does not shake.

[0045] Furthermore, as shown in Figure 7 and Figure 8 , the positioning member 6 includes a base 61 connected to the ship's side b. An activity groove 612 with an inverted "T" shaped longitudinal profile is provided at the top of the base 61. A slider 62 is slidably clamped in the activity groove 612, and a positioning block 63 is connected to the top of the slider 62. The top of the positioning block 63 is a tapered hopper structure with a narrow top and a wide bottom, which is convenient for docking with the leg 15. A bolt locking structure is formed between the bottom of the positioning block 63 and the slider 62. When the positioning block 63 is locked, the slider 62 is locked in the activity groove 612. After the positioning block 63 is loosened, the slider 62 can reciprocally slide in the activity groove 612 for position adjustment to ensure accurate positioning. Connecting holes 611 are provided on both sides of the activity groove 612 of the base 61. The connecting holes 611 longitudinally penetrate the base 61 and are used to cooperate with self-locking screws to fixedly install the base 61 on the ship's side b.
