Detailed implementation mode

[0022] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the specific embodiments cited are not intended to limit the present utility model.

[0023] This embodiment provides an automatic door opening and closing actuator, which is installed on the door body, can meet the compound track-changing movement requirements for opening the door body, can provide a large torque during the pushing and pulling process, making the opening and closing of the door more convenient, and the actuator of the present utility model can also seamlessly switch between manual operation and automatic operation, making it more convenient to use.

[0024] Combined with Figures 1 to 3 As shown, the automatic door opening and closing actuator of this embodiment includes a hinge part 10 and a driving part 20. The hinge part 10 is installed on the door body, and the driving part 20 drives the hinge part 10 to achieve automatic or manual opening of the door body.

[0025] In this embodiment, the automatic door opening and closing actuator further includes a base 30 and an angle measurement part 40. The driving part 20 is arranged in the base 30, and the angle measurement part 40 monitors the opening angle of the door body in real time.

[0026] Combined with Figure 1 And Figure 2 As shown, the hinge part 10 of this embodiment includes a first hinge bracket 11 and a second hinge bracket 12. The first hinge bracket 11 rotates relative to the second hinge bracket 12. The first hinge bracket 11 is located at the rotating end of the door body, and the second hinge bracket 12 is located at the fixed end of the door body. When opening the door body, the first hinge bracket 11 rotates relative to the second hinge bracket 12 to drive the rotating end of the door body to rotate, realizing the opening of the door body.

[0027] In this embodiment, the first hinge bracket 11 and the second hinge bracket 12 are hinged, so the first hinge bracket 11 can rotate relative to the second hinge bracket 12 to drive the door body to open.

[0028] Such as Figure 1As shown in the figure, the driving part 20 of this embodiment includes a driver 21, a transmission structure 22, and a driving lead screw 23. The driver 21 drives the driving lead screw 23 to rotate through the transmission structure 22. The driving lead screw 23 penetrates through the first hinge bracket 11 and is hinged to the fixed end of the door body. When the driving lead screw 23 rotates, the driving part 20 rotates synchronously with the first hinge bracket 11. In this embodiment, the driver 21 is a motor, and this motor is installed in the base 30. When driving the door body, the driver 21 drives the driving lead screw 23 through the transmission structure 22 to make the driving lead screw 23 rotate. During the rotation of the driving lead screw 23, since one end is hinged to the fixed end of the door body, the driving lead screw 23 will rotate synchronously with the first hinge bracket 11, driving the rotating end of the door body to rotate.

[0029] In this embodiment, a clutch 31 is arranged in the base 30. The transmission structure 22 includes a first-stage gear set 221 and a second-stage gear set 222. The first-stage gear set 221 connects the driver 21 and the clutch 31, and the second-stage gear set 222 connects the driving lead screw 23 and the clutch 31. Under the combined action of the first-stage gear set 221 and the second-stage gear set 222, the clutch 31 realizes the clutch function, which can provide torque protection for the actuator and avoid product damage caused by the user's rough operation.

[0030] Further, a hinge seat 50 is arranged at one end of the driving lead screw 23, and the driving lead screw 23 is hinged to the fixed end of the door body through the hinge seat 50.

[0031] Combined Figure 1 with Figure 3 As shown in the figure, the angle measurement part 40 of this embodiment is installed on the first hinge bracket 11 to measure the deflection angle of the first hinge bracket 11. The angle measurement part 40 includes a synchronous gear 41, a transmission gear 42, and an angle sensor 43. The synchronous gear 41 is fixedly connected to the first hinge bracket 11 and rotates synchronously with the first hinge bracket 11. The transmission gear 42 meshes with the synchronous gear 41 to drive the transmission gear 42 to rotate. The angle sensor 43 is fixedly installed on the transmission gear 42 to monitor the rotation angle of the transmission gear 42. During the rotation of the first hinge bracket 11, under the meshing action of the synchronous gear 41 and the transmission gear 42, the angle sensor 43 realizes real-time monitoring of the rotation angle of the first hinge bracket 11.

[0032] In this embodiment, when the driving part 20 is not started, the user can manually rotate the rotating end of the door body, realizing seamless switching between manual operation and automatic operation, which is more convenient to use.

[0033] Obviously, the above embodiments are merely examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the creation of the present utility model.
