DETAILED DESCRIPTION

[0027] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the accompanying drawings, in which typical embodiments of the present invention are shown.

[0028] Embodiment 1:

[0029] like Figure 1 , Figure 2 , Figure 3 As shown, the present embodiment discloses a hidden automatic handle, including a shell 1, a push rod 2, a swing arm 3, a handle 4, and a driving device 5. There are two swing arms 3, and the swing arms 3 are distributed along the length direction of the shell 1. The swing arm 3 includes a first hinge end 31 and a second hinge end 32. The first hinge end 31 is rotatably connected to the shell 1 through a rotating shaft 6. The rotating shaft 6 vertically passes through the shell 1 and the swing arm 3. The swing arm 3 can rotate horizontally around the rotating shaft 6.

[0030] like Figure 2 , Figure 4, Figure 5 As shown, the handle 4 includes a grip plate 42 and two connecting rods 41. The grip plate 42 is located outside the shell 1, and the connecting rods 41 penetrate the shell 1. Each connecting rod 41 is rotatably connected to a second hinge end 32. The connecting rods 41 and the grip plate 42 are vertically arranged. The shell 1 is provided with a hole for the connecting rod 41 to pass through. One end of the connecting rod 41 extending into the shell 1 is hinged to the second hinge end 32 of the swing arm 3. When the swing arm 3 rotates horizontally around the rotating shaft 6, it can drive the connecting rod 41 to move, so that the grip plate 42 can be close to or away from the shell 1, so that the handle 4 has a telescopic function.

[0031] like Figure 4 , Figure 5 As shown, Figure 4 When the handle 4 is retracted, the driving device 5 is installed on the shell 1, and the push rod 2 is located below the two swing arms 3. The push rod 2 extends in the length direction of the shell 1. The push rod 2 is provided with two rollers 22, and each roller 22 is against a swing arm 3. When the handle 4 needs to be extended, the telescopic rod 51 of the driving device 5 pushes the push rod 2 to move along the length direction of the shell 1, and then the roller 22 can push the swing arm 3 to rotate. The roller 22 can reduce the friction force when the push rod 2 pushes the swing arm 3 to prevent contact and jamming between the push rod 2 and the swing arm 3. The rotation of the swing arm 3 can push the connecting rod 41 toward the outside of the shell 1, drive the grip plate 42 away from the shell 1, and extend the handle 4 out of the shell 1.

[0032] like Figure 3 As shown, the shell 1 is provided with at least two waist-shaped holes 11, which are distributed along the length direction of the shell 1. The lower end surface of the push rod 2 is provided with a limiting column 24 corresponding to the waist-shaped hole 11. The diameter of the limiting column 24 is the same as the width of the waist-shaped hole 11. The waist-shaped hole 11 plays a guiding and limiting role for the moving direction of the push rod 2.

[0033] like Figure 4 , Figure 5 , Figure 6 As shown, the rotating shaft 6 is installed with a torsion spring 61, and the torsion spring 61 includes a first end 611 and a second end 612. The shell 1 is provided with a baffle 12, and the first end 611 abuts against the baffle 12, and the second end 612 abuts against the swing arm 3. When the driving device 5 pushes the push rod 2, it can overcome the elastic force of the torsion spring 61 to push the swing arm 3 to rotate. When the driving device 5 removes the thrust on the push rod 2, the torsion spring 61 can restore the position of the swing arm 3 and can make the swing arm 3 always abut against the roller 22.

[0034] like Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, the push rod 2 includes a push plate 21, which is located at one end of the push rod 2 facing the driving device 5. The driving device 5 includes a telescopic rod 51, which can resist the push plate 21. The push plate 21 and the telescopic rod 51 are not fixedly connected to prevent the telescopic rod 51 from being damaged when the handle 4 is pulled. The telescopic rod 51 only resists the push plate 21. Similarly, the torsion spring 61 can apply force to the swing arm 3 to make the swing arm 3 resist the roller 22 and then make the push plate 21 resist the telescopic rod 51.

[0035] like Figure 3 , Figure 6 As shown, more preferably, the torsion spring 61 is located below the swing arm 3, the swing arm 3 is provided with a slot 33, a portion of the torsion spring 61 is located in the slot 33, the second end 612 is located in the slot 33, the second end 612 is against the inner wall of the slot 33, a portion of the torsion spring 61 is embedded in the slot 33, and can be better installed and cooperated with the swing arm 3 to prevent the second end 612 of the torsion spring 61 from detaching from the swing arm 3.

[0036] More preferably, a limit rod 7 is installed on the shell 1, and the limit rod 7 is located on the side of the rotating shaft 6 away from the driving device 5. The swing arm 3 can resist the limit rod 7, and the limit rod 7 can limit the stroke of the swing arm 3. When the user pulls the handle 4, the limit rod 7 will be subjected to force, which can protect the swing arm 3 and the torsion spring 61 and prevent the swing arm 3 and the torsion spring 61 from being damaged due to excessive force when pulling the handle 4.

[0037] like Figure 2 , Figure 4 , Figure 5 As shown, the present embodiment further includes a distance sensor 9, which is electrically connected to the driving device 5. The distance sensor 9 is installed on the inner wall of the shell 1, and the probe of the distance sensor 9 penetrates the shell 1 toward the grip plate 42. The handle 4 can be automatically extended upon receiving the induction. When the door needs to be closed, the user closes the door and separates the hand from the handle 4. The probe of the distance sensor 9 cannot sense the object between the handle 4, and the driving device 5 will be reset. The torsion spring 61 will reset the swing arm 3, and the grip plate 42 can be close to the shell 1, so as to automatically reset the handle 4. The distance sensor 9 can prevent the hand from being pinched when the handle 4 is retracted.

[0038] like Figure 2 , Figure 4 , Figure 5As shown, the present embodiment further includes a reset device 8, which is installed inside the housing 1. The reset device 8 is provided with a reset switch 81, which faces the push rod 2. The push rod 2 is provided with a protrusion 23, which faces the reset device 8. The push rod 2 moves, and the protrusion 23 can toggle the reset switch 81. During the process of the push rod 2 pushing the handle 4 to extend, the protrusion 23 will toggle the reset switch 81 once. The reset device 8 sends a signal to pause the operation of the machine. When the handle 4 is retracted, the swing arm 3 pushes the push rod 2, and the protrusion 23 will toggle the reset switch 81 once again. The reset device 8 sends a signal. At this time, the handle 4 is reset, and the machine can be started, which can prevent the machine from still running and splashing water outward when the door is opened.

[0039] like Figure 3 , Figure 4 As shown, the handle 4 includes a patch 43, which is installed on the side of the grip plate 42 away from the shell 1. The patch 43 can completely cover the grip plate 42. The patch 43 can be replaced according to the material of the installed door panel, so that the patch 43 and the installed door panel use the same material. When the handle 4 is hidden in the door panel, it can be more complete and more beautiful with the door panel.

[0040] Embodiment 2:

[0041] like Figure 7 , Figure 8 As shown, this embodiment discloses a door panel, including a door body 101, a sensor 102 and the hidden automatic handle in Example 1, the shell 1 is installed on the inner wall of the door body 101, the sensor 102 is installed on the inner wall of the door body 101, the sensor 102 is located on one side of the shell 1, when the grip plate 42 is closest to the shell 1, the surface of the handle 4 is flush with the outer surface of the door body 101, the handle 4 is usually retracted into the door body 101 and can be hidden in the door body 101, the whole door is more integrated and more beautiful, the sensor 102 is located near the handle 4, the sensor 102 is electrically connected to the distance sensor 9, the user's hand is close to the bottom of the handle 4 or other positions, the door body 101 is provided with a sensor 102 which can sense the user's hand to trigger the distance sensor 9, send a signal, and the drive device 5 starts to work to extend the handle 4.
