DETAILED DESCRIPTION

[0019] The utility model will be further described below in combination with the drawings and specific embodiments.

[0020] Embodiment 1

[0021] The sunshade machine in this example comprises a shell 1, a power mechanism 2, a speed reducer 8, a screw nut mechanism 3, and an electric control box 7. Figure 1 、 Figure 2 As shown in the configuration, the shell 1 comprises a rectangular frame 10 and a guide rod 11 connected to the frame 10. The power mechanism 2, the speed reducer 8, and the screw nut mechanism 3 are installed in the cavity of the frame 10. The power mechanism 2 is a driving motor, for example. The speed reducer can be selected from the market according to requirements. The output end of the power mechanism 2 is connected to the input end of the speed reducer 8. The output end of the speed reducer 8 is connected to the bottom end of the screw rod 31 in the screw nut mechanism 3. The output end of the speed reducer 8 is fixed to the bottom end of the screw rod 31 through a flange or the like. Of course, the guide rod can be omitted. The two ends of the connecting plate are slidably connected to the sliding grooves of the frame through sliding blocks.

[0022] The guide rod 11 is fixed in the cavity of the frame 10 at the two sides of the screw rod 31. The cylindrical guide sleeve 12 is slidably connected to the guide rod 11. The guide sleeve 12 is fixed to the end of the flat connecting plate 4. The other end of the connecting plate 4 is fixed to the nut 32 in the screw nut mechanism 3. The connecting plate 4 connects the guide sleeve 12 and the nut 32. The guide sleeve 12 cooperates with the guide rod 11 to move the nut 32 along the length direction of the screw rod 31.

[0023] Limit switches 6 are installed at intervals in the moving direction of the connecting plate 4. In this example, the upper and lower positions of the connecting plate are determined according to the measured extension state of the sunshade. Limit switches 6 are installed at the positions adjacent to the upper and lower positions. The position of the connecting plate is detected by the limit switches 6. The electric control box 7 is connected to the limit switches 6 and the power mechanism 2.

[0024] In use, the top end of the screw rod is connected to the crank 15, which is connected to the driving hook of the sunshade. The electric control box controls the output of the power mechanism. The screw rod and the crank rotate synchronously to drive the sunshade to extend. The connecting plate moves upward to a predetermined position above the connecting plate under the transmission of the screw nut. The predetermined position is within the detection range of the limit switch. After the limit switch detects the connecting plate, it feeds back a signal to the electric control box. The electric control box drives the power mechanism to reverse. The screw rod reversely rotates synchronously to drive the crank to reverse. The sunshade is retracted. The connecting plate moves downward to a predetermined position below the connecting plate. The predetermined position is within the detection range of the limit switch. After the limit switch detects the connecting plate, it feeds back a signal to the electric control box. The electric control box drives the power mechanism to reverse again. The cycle can be repeated. The durability of the sunshade can be intuitively reflected by the number of cycles.

[0025] For the electric control box, such as the electric control box 7 is fixed on the frame 10 top wall above the power mechanism 2. A counter 9 can also be installed on the electric control box 7, which measures the number of cycles of the connecting plate 4 between the upper and lower limit switches, and the number of cycles of the connecting plate corresponds to the number of extension and retraction of the awning, giving a more intuitive experience. Of course, the counter can also be omitted, and the required time for one cycle of the connecting plate can be directly calculated.

[0026] To facilitate the docking with the ratchet handle, a shaft coupling 13 is installed at the top end of the lead screw 31 in the lead screw nut mechanism 3 in this example, so that the shaft coupling can be docked with the ratchet handle and the like. Preferably, a connecting rod assembly 5 is added, which includes a connecting cylinder 52, a connecting rod 51, and a clamping seat 53. The connecting rod 51 is rotationally connected to the box body 14 at the top surface of the frame, and the shaft coupling 13 is located in the cavity of the box body 14. The bottom end of the connecting rod 51 is connected to the shaft coupling 13, and the top end is connected to the connecting cylinder 52. The clamping seat 53 is fixed at the top end of the connecting cylinder 52. The clamping seat is columnar, and has a slot at the top surface. In use, the bottom end of the ratchet handle can be directly inserted into the slot. Of course, a notch can also be added to the opposite slot wall of the slot. The clamping seat is made of plastic or other materials. Under the action of the notch, the aperture of the slot can be easily changed, and can accommodate ratchet handles of various sizes.

[0027] For the fixation of the clamping seat and the connecting cylinder, the bottom end of the clamping seat 53 is inserted into the top end cylinder cavity of the connecting cylinder 52. A bolt is used as a fastener one, which is screwed into the threaded hole at the bottom end of the clamping seat from the radial wall of the connecting cylinder to fix it as a whole. A sliding groove 54 can also be formed on the cylinder body of the connecting cylinder 52 in the axial direction. The top end of the connecting rod 51 is inserted into the cylinder cavity. A bolt is used as a fastener two, which is screwed into the threaded hole at the top end of the connecting rod from the sliding groove to fix it as a whole. Through the sliding groove, the size of the connecting rod inserted into the cylinder cavity can be adjusted, thereby adapting to ratchet handles of different lengths.

[0028] The above is only a preferred embodiment of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiments. Any technical solutions falling within the scope of the present application should be considered within the protection scope of the present application. It should be noted that for ordinary technical personnel in the technical field, some improvements and refinements without departing from the principles of the present application should also be considered within the protection scope of the present application.
