[0025] Reference Figure 1-4 The figure shows a preferred embodiment of the present invention.
[0026] A push rod structure for adjusting the steering direction of a solar panel includes an outer tube 10 and a tube base 20. One end of the tube base 20 is threadedly connected to the outer tube 10. A screw 60 is provided in the outer tube 10. The screw 60 and the tube base 20 are connected via a thrust ball bearing 61. A sheet metal seat 50 made of metal is installed on the other end of the tube base 20. A shell 30 made of plastic is provided on the outer side of the sheet metal seat 50. The shell 30 encapsulates the sheet metal seat 50 and the tube base 20. A rotating shaft 70 connected to an external device is provided on the sheet metal seat 50. A driving bevel gear 71 is installed on the rotating shaft 70. A driven bevel gear 62 is installed on the screw 60. The driven bevel gear 62 is meshed with the driving bevel gear 71.
[0027] A tail end cover 40 made of plastic material is installed on the shell 30, and a tube plate 54 is provided on the sheet metal seat 50. The tube plate 54 is located in the tail end cover 40, and a tube hole 55 is provided on the tube plate 54. The tube hole 55 passes through the tail end cover 40 and the tube plate 54.
[0028] The push rod structure provided above for adjusting the steering direction of the solar panel, when the screw 60 is subjected to tension, since the screw 60 is connected to the thrust ball bearing 61, after the tension is transmitted to the thrust ball bearing 61, the tube seat 20 is subjected to a tension to the left. Since the tube seat 20 is connected to the sheet metal seat 50 with screws, the sheet metal seat 50 and the tube plate 54 are fixed in the tube hole 55 and other fixing devices. According to Newton's third law, the sheet metal seat 50 and the tube plate 54 are subjected to a tension to the right; when the push rod is subjected to pressure, the force it receives is opposite to the direction of the tension. It can be seen that the sheet metal seat 50 is the main force-bearing component, and its tensile and compressive resistance directly determines whether the push rod can work normally under load; it not only ensures that the push rod can work normally under increased rated load, but also greatly reduces the cost of the push rod and stabilizes the force strength; it solves the problem of unstable force during the driving process of the photovoltaic push rod.
[0029] The sheet metal seat 50 and the tube seat 20 are encapsulated and wrapped on the outer tube 10 by the outer shell 30 and the tail end cover 40 , thereby improving the waterproofness of the sheet metal seat 50 , the tube seat 20 and the outer tube 10 .
[0030] The external device drives the rotating shaft 70 to rotate, and the circular motion is converted into linear motion of the push rod through the transmission of the active bevel gear 71 and the driven bevel gear 62 and the spiral transmission of the screw 60, thereby realizing the push-pull function; when the push rod is subjected to pressure, the force it receives is opposite to the direction of the pulling force. It can be seen that the sheet metal seat 50 is the main force-bearing component, and its tensile and compressive resistance directly determines whether the push rod can work normally under load; and the use of the sheet metal seat 50 and its plastic shell 30, the materials used are compared with most aluminum die-casting materials on the market, which not only ensures that the push rod can work normally under increased rated load, but also greatly reduces the cost of the push rod.
[0031] In this embodiment, the sheet metal seat 50 has a vertical plate 51 on both ends that is bent and extended upward. The vertical plate 51 is provided with a side hole 52 for the rotating shaft 70 to pass through. One end of the rotating shaft 70 passes through the side holes 52 on the two vertical plates 51, and the two sides of the outer shell 30 are respectively penetrated with side holes 52.
[0032] The sheet metal seat 50 increases the force stability of the rotating shaft 70 through the vertical plate 51 , and the vertical plate 51 is installed by the common rotating shaft 70 through the side hole 52 .
[0033] In this embodiment, the bottom of the vertical plate 51 is docked on the sheet metal seat 50 , and a horizontal plate 53 is arranged between the tops of the two vertical plates 51 and extends toward each other in a curved manner. The tail cover 40 is sealed on the horizontal plate 53 .
[0034] The vertical plate 51 increases the stability of the housing 30 and the tail end cover 40 during installation using the horizontal plate 53 , and increases the bearing capacity of the tube plate 54 .
[0035] In this embodiment, two vertical plates 51 spaced apart from each other, two horizontal plates 53 at the same horizontal position, and the sheet metal base 50 enclose a linkage cavity 56, and the driving bevel gear 71 and the driven bevel gear 62 are respectively located in the linkage cavity 56. This facilitates the driving bevel gear 71 and the driven bevel gear 62 to have a linkage position.
[0036] In this embodiment, the two horizontal plates 53 are arranged relatively spaced apart, the inner ends of the horizontal plates 53 are docked on the top of the vertical plates 51, and the outer ends of the horizontal plates 53 are docked on the bottom of the tube plates 54. The tube plates 54 and the horizontal plates 53 are arranged relatively vertically.
[0037] The tube sheet 54 is fixed to other fixing devices through the tube holes 55 , and the tube sheet 54 uses the horizontal plate 53 to increase its own bearing capacity and tensile force.
[0038] The sheet metal base 50, the vertical plate 51, the horizontal plate 53 and the tube plate 54 are connected in sequence to form an integrated structure, thereby increasing the overall bearing capacity and overall stability of the sheet metal base 50.
[0039] In this embodiment, the sheet metal seat 50 has a bottom hole 57 for the screw 60 to pass through. The bottom hole 57 passes through the middle of the sheet metal seat 50 from top to bottom. The bottom hole 57 is connected to the side hole 52 through a linkage cavity 56.
[0040] The sheet metal seat 50 can allow the screw 60 to pass through the bottom hole 57 , so that the screw 60 can be connected to the driving bevel gear 71 through the driven bevel gear 62 .
[0041] In this embodiment, the thrust ball bearing 61 is connected to the screw 60 via a guide sleeve 63 .
[0042] The screw 60 is threadedly connected to the inner end of the inner tube 65 through the nut sleeve 64. The inner end of the inner tube 65 is inserted into the outer tube 10. The inner end of the inner tube 65 and the outer tube 10 are slidingly fitted, and the outer end of the inner tube 65 is exposed outside the outer tube 10.
[0043] Deep groove ball bearings 72 are mounted on both sides of the rotating shaft 70. The deep groove ball bearings 72 are mounted on the side holes 52 of the vertical plate 51 via fixed sleeves 73. The fixed sleeves 73 seal the side holes 52 of the housing 30. In this way, the deep groove ball bearings 72 can be sealed against the side holes 52 by the fixed sleeves 73, thereby preventing water and vibration.
[0044] The external device drives the rotating shaft 70 to rotate, and through the transmission of the active bevel gear 71 and the driven bevel gear 62 and the spiral transmission of the screw 60, the circular motion is converted into the linear motion of the push rod, thereby realizing the push-pull function;
[0045] When the inner tube 65 is subjected to tension, the tension is transmitted to the screw 60 through the nut sleeve 64. Since the screw 60 is connected to the nut, the tension is transmitted to the thrust ball bearing 61, and the tube seat 20 is subjected to a tension to the left. Since the tube seat 20 is connected to the sheet metal seat 50 with screws, the sheet metal seat 50 and the tube plate 54 are fixed to the tube hole 55 and other fixing devices. According to Newton's third law, the sheet metal seat 50 and the tube plate 54 are subjected to a tension to the right.
[0046] When the push rod is subjected to pressure, the force it receives is in the opposite direction to the pulling force. It can be seen that the sheet metal seat 50 is the main force-bearing component, and its tensile and compressive resistance directly determines whether the push rod can work normally under load. The use of the sheet metal seat 50 and its plastic shell 30, compared with most aluminum die-cast materials on the market, not only ensures that the push rod can work normally under increased rated load, but also greatly reduces the cost of the push rod.
[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
