The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0025] Figure 1 is a schematic diagram of a wing 1100 of an opening and closing power device according to an embodiment of the present application, Figure 2 It is a schematic diagram of an opening and closing power device 1000 according to an embodiment of the present application.
[0026] refer to Figure 1 and Figure 2 , the opening and closing power device 1000 includes: a worm gear bearing seat 1300, a worm wheel 1400, a worm 1500, a transition shaft 1600 and a wing 1100. Among them, the worm wheel 1400 is slidably sleeved on the worm gear bearing seat 1300; the worm wheel 1400 is meshedly connected with the worm 1500, and the worm 1500 has a spiral tooth surface; one end of the transition shaft 1600 is fixedly connected with the worm wheel 1400; the wing 1100 is fixedly connected with the other end of the transition shaft 1600. Specifically, the meshing connection between the worm wheel 1400 and the worm 1500 is a mechanism for realizing staggered transmission of two axes through a spiral tooth surface. In this mechanism, the motion trajectory of the worm 1500 is presented as a continuous spiral line, thereby ensuring that the worm wheel 1400 meshedly connected thereto can operate stably. Compared with the gear connection, this structure exhibits higher stability.
[0027] Figure 3 It is a schematic diagram of the first worm gear bearing 1800 of the opening and closing power device 1000 according to an embodiment of the present application.
[0028] refer to Figure 2 and Figure 3 The opening and closing power device 1000 further includes a driving device 1700, and the driving device 1700 is slidably connected to one end of the worm 1500. Optionally, the driving device 1700 may be a motor. Alternatively, the driving device 1700 may also be a cylinder.
[0029] Specifically, under the drive of the driving device 1700, the worm 1500 can rotate clockwise or counterclockwise. When the worm 1500 rotates clockwise, the spiral tooth surface of the worm 1500 drives the worm wheel 1400 to rotate clockwise synchronously, thereby driving the wing 1100 to open. At the same time, when the helix angle of the worm 1500 is set to be small, the worm 1500 and the worm wheel 1400 can form a self-locking structure, in which the worm 1500 can only drive the worm wheel 1400 to transmit, and the worm wheel 1400 cannot drive the worm 1500 to rotate. Therefore, the self-locking structure formed by the worm wheel 1400 and the worm 1500 can prevent the worm 1500 from easily reversing due to the external force when the wing 1100 is subjected to the external force, thereby ensuring the stable opening state of the wing 1100. The helix angle can be determined according to the friction between the worm wheel 1400 and the worm 1500. This self-locking structure not only avoids the need for the drive device 1700 to continuously provide power to maintain the open state of the wing 1100, thereby achieving energy conservation, but also reduces the wear between the gears, which is beneficial to the maintenance of the device. When the wing 1100 needs to be folded, the worm 1500 will rotate counterclockwise. At this time, the spiral tooth surface of the worm 1500 will drive the worm wheel 1400 to rotate counterclockwise, thereby driving the wing 1100 to close in an orderly manner. Similarly, the self-locking structure ensures that during the closing process of the wing 1100, the worm 1500 will not accidentally reverse due to external force.
[0030] Figure 4 It is a schematic cross-sectional view of the second worm gear bearing 1900 of the opening and closing power device 1000 according to the embodiment of the present application.
[0031] refer to Figure 3 and Figure 4 The opening and closing power device 1000 also includes a first worm gear bearing 1800, wherein the first worm gear bearing 1800 includes an inner ring 1801 and an outer ring 1802 that are slidably sleeved with each other, the inner ring 1801 of the first worm gear bearing is fixedly sleeved on the worm gear bearing seat 1300, and the outer ring 1802 of the first worm gear bearing is fixedly connected to the worm gear 1400. The connection structure between the first worm gear bearing 1800 and the worm gear 1400 ensures the stable rotation of the worm gear 1400 and reduces the friction loss during the movement. At the same time, the structure of the first worm gear bearing 1800 can effectively withstand the huge radial force and axial force generated when the worm gear 1400 is driven, ensure the rotation accuracy of the worm gear 1400 when it is driven, and enhance its bearing capacity.
[0032] refer to Figure 4 The opening and closing power device 1000 also includes a second worm gear bearing 1900 , wherein the second worm gear bearing 1900 includes an inner ring 1901 and an outer ring 1902 slidably sleeved with each other, and the inner ring 1901 of the second worm gear bearing is fixedly sleeved on the transition shaft 1600 .
[0033] refer to Figure 1 and Figure 4 , the opening and closing power device 1000 also includes a support plate 1200, and the outer ring 1902 of the second worm gear bearing is fixedly connected to the support plate 1200. Specifically, the inner side of the support plate 1200 has a machined countersunk hole (not shown), and the machined countersunk hole matches the size of the outer ring 1902 of the second worm gear bearing. This can prevent the second worm gear bearing 1900 from offsetting or shaking during movement, thereby ensuring the stability of the transition shaft 1600. When the support plate 1200 can effectively fix the outer ring 1902 of the second worm gear bearing, the transition shaft 1600 can maintain its stable position and state, thereby ensuring that the power transmission of the worm gear 1400 is more stable.
[0034] refer to Figure 2 The opening and closing power device 1000 also includes a fixing plate 1200 , a worm gear bearing seat 1300 is fixed on the fixing plate 1200 , and a driving device 1700 is fixed on the fixing plate 1200 .
[0035] refer to Figure 3 The opening and closing power device 1000 also includes a first worm bearing seat 1510 and a second worm bearing seat 1520, and the first worm bearing seat 1510 and the second worm bearing seat 1520 are fixed on the fixed plate 1200, wherein: the first worm bearing seat 1510 is slidably connected to one end of the worm 1500; the second worm bearing seat 1520 is slidably connected to the other end of the worm 1500. Specifically, the first worm bearing seat 1510 and the second worm bearing seat 1520 are fixed on the fixed plate 1200, ensuring the straightness and stability of the worm 1500. If the worm 1500 needs to be repaired or replaced, it is only necessary to disassemble the corresponding bearing seat, without the need to disassemble the entire opening and closing power device 1000 on a large scale, which is convenient for the maintenance of the opening and closing power device 1000.
[0036] refer to Figure 3 The opening and closing power device 1000 also includes a first worm bearing 1511 and a second worm bearing 1521 having an inner ring (not shown) and an outer ring (not shown) that are slidably connected to each other, wherein: the outer ring of the first worm bearing 1511 is fixedly connected to the first worm wheel bearing seat 1510, and one end of the worm 1500 is fixedly connected to the inner ring of the first worm bearing 1511; the outer ring of the second worm bearing 1521 is fixedly connected to the second worm wheel bearing seat 1520, and the other end of the worm 1500 is fixedly connected to the inner ring of the second worm bearing 1521.
[0037] Specifically, the inner and outer ring sliding sleeve design of the first worm bearing 1511 and the second worm bearing 1521 not only ensures the stable rotation of the worm 1500, but also allows the worm 1500 to have a certain space for movement, which enables the worm 1500 to have a certain degree of freedom for adjustment under the influence of vibration or external force, thereby protecting the power transmission structure of the worm 1500 and enhancing stability and durability.
[0038] The transmission ratio of the worm wheel 1400 and the worm 1500 is 40: 1 to 60: 1. This transmission ratio design enables the transmission structure of the worm wheel 1400 and the worm 1500 to have a significant deceleration function, and is suitable for the opening and closing power device 1000 that requires high-precision control and torque transmission.
[0039] The module of the worm 1500 is 1.5 to 3. The design of the module of 1.5 to 3 enables the opening and closing power device 1000 to withstand a large load.
[0040] The above description is only an implementation method of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of protection involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the technical concept.
