[0028] According to an embodiment of the present invention, an electric multifunctional oral opening device is provided.

[0029] Example 1

[0030] like Figure 1-6 As shown, an electric multifunctional oral opener according to an embodiment of the present invention includes a main body shell 1, which is divided into a front area and a rear area; an upper support plate 2 is provided on the top of the outer side of the front area, a lower support plate 3 is slidably provided on the middle and lower part of the outer side of the front area, and slide rails 15 for installing a slide rod 16 are provided on both sides of the inner side of the front area, and the lower support plate 3 can be detachably installed on the slide rod 16; a motor 6 is installed in the middle of the rear area, a fixing frame 7 is built into the rear area, and a through hole is provided in the middle of the fixing frame 7 for the transmission shaft of the motor 6 to pass through, and the fixing frame 7 has a fixed portion. The frame 7 is provided with several transmission wheels 11 around the through hole; several transmission wheels 11 are provided with gear rings 9 on the outside, and a cross bracket 8 is provided on the gear ring 9, and the cross bracket 8 is movably connected to the slide rod 16 through a block 12; a driving wheel 10 that engages with the transmission wheel 11 is fixedly provided on the transmission shaft of the motor 6, and the motor 6 is electrically connected to a battery provided in the rear area of the main shell 1, and a control system is provided between the motor 6 and the battery, and the control system includes a power button 18, a lower movement button 19, an upper movement button 20 and a control circuit.

[0031] The power design in the present invention is relatively simple, and the conventional motor forward and reverse design is not drawn separately. In the control system, when the power button 18 is turned off, the control system is not powered, the upper movement button 20 and the lower movement button 19 are invalid, the motor 6 is not powered, and the motor 6 is self-locking and fixed. When the power button 18 is turned on, the control system is powered, the upper movement button 20 and the lower movement button 19 are valid, but the motor 6 is not powered, and the motor 6 is self-locking and fixed. When the power button 18 is turned on, when the upper movement button 20 is pressed, the motor 6 is powered, and the rotation of the motor 6 drives the transmission wheel 11 to rotate through the driving wheel 10, and then drives the ring gear 9 to rotate, and the ring gear 9 synchronously drives the cross bracket 8 to rotate, so that the block 12 installed in the block mounting hole 23 moves, because the block 12 is located in the block motion track 17 in the slide bar 16, and the slide bar 16 is located in the slide rail, and then the upper curvature motion of the block 12 drives the slide bar 16 to move upward, further driving the lower support plate 3 to move upward. When the power button 18 is turned on and the movement button 20 is pressed, the motor 6 is energized, and the motor 6 rotates through the drive wheel 10, driving the transmission wheel 11 to rotate, thereby driving the ring gear 9 to rotate. The ring gear 9 synchronously drives the cross bracket 8 to rotate, causing the block 12 installed in the block mounting hole 23 to move. Because the block 12 is located in the block movement track 17 inside the slide bar 16, and the slide bar 16 is located in the slide rail, the downward arc movement of the block 12 drives the slide bar 16 to move downward, further driving the lower support plate 3 to move downward. The motor 6 is a low-speed motor, or a motor reducer can be installed according to actual needs.

[0032] Example 2

[0033] On the basis of embodiment 1, the upper support plate 2 is detachably connected to the main housing 1 via a support plate connector 5. The connection may be to the main housing 1 or to a fixing frame.

[0034] Example 3

[0035] On the basis of Example 1, a slider 13 is provided on the slide rod 16, and the lower support plate 3 is fixedly connected to the slider 13 through the support plate connector 5; the slider is a slider that moves along the slide groove 22, and the slider 13 is driven to move by the slide rod 16. A strip-shaped block motion track 17 is provided in the middle of the slide rod 16, and the block motion track 17 is used for the movement of the block 12.

[0036] Example 4

[0037] On the basis of Example 1, the support plate connecting member 5 is a movable connecting member, and the support plate connecting member 5 includes a snap-on connection, a pin connection and a threaded connection.

[0038] Example 5

[0039] Based on Example 1, a lower support plate motion guide surface 4 is provided at the lower middle portion of the front outer side of the main housing 1. A slide groove 22 is provided together with the lower support plate motion guide surface 4 and the upper middle portion of the front outer side of the main housing 1. The lower support plate motion guide surface 4 is designed to mimic the arc of the opening and closing of the mouth.

[0040] Example 6

[0041] On the basis of Example 1, the lower support plate motion guide surface 4 is designed to imitate the opening and closing arcs of the oral cavity. The lower support plate motion guide surface 4 is bionic in design.

[0042] Example 7

[0043] Based on Example 1, the cross bracket 8 is provided with 1-4 stopper mounting holes 23, and the stopper 12 for limiting the movement of the slide bar 16 is mounted on the stopper mounting holes 23. Different installation positions of the stopper 12 result in different movement ranges of the lower support plate 3, that is, different opening ranges of the opener, making it more applicable.

[0044] Example 8

[0045] Based on Example 1, the number of the transmission wheels 11 is 2-4. In order to maintain the movement of the ring gear 9, the number cannot be less than 2, and 3 to 4 are most appropriate. Too many will increase its weight.

[0046] Example 9

[0047] On the basis of Example 1, the motor 6 is fixed to the rear area of the main housing 1 and is assisted in fixing by a rear cover 14 installed at the rear area of the main housing 1 .
