Although many cabinet doors and control panels of furniture, kitchen utensils and household appliances can be opened and turned up and are convenient for users to operate. However, the reliability of the overturning structure is relatively poor, and the overturning structure is easily damaged after long-term use, and the cabinet door or the control panel needs to be manually turned up and reset. Therefore, if the cabinet doors and control panels of furniture, kitchen utensils, and household appliances can be pushed out and turned up to a certain angle, the user can directly operate while standing, and the user experience is better. At present, there is no mechanism in the domestic market that can realize furniture, kitchen utensils and home appliance cabinet doors and control panels to automatically push up and reset functions. However, with the intelligent development of furniture, kitchen utensils and home appliances, the operation interface of the control panel needs to carry more functions. , and future high-end smart models, the operation interface will inevitably integrate audio-visual Internet access and other functions. Therefore, in order to improve the convenience and comfort of the product, it is valuable to realize the functions of automatically pushing out and turning up and automatically resetting the cabinet door and the control panel.

As shown in Fig. 1, Fig. 2 and Fig. 3, an automatic push-out and upturn reset mechanism includes a support frame 6, a drive mechanism, a transmission shaft 7, an idler wheel 14, a transmission mechanism one and a transmission mechanism two; the drive mechanism includes a drive motor 13. Motor bracket 12 and driving gear 10; the base of driving motor 13 is fixed on motor bracket 12 by bolts, and motor bracket 12 is fixed on support frame 6; driving gear 10 is fixed on the output shaft of driving motor 13; driving motor 13 It has the functions of forward rotation, reverse rotation and self-locking; the idler 14 and the supporting frame 6 constitute a revolving pair, and the structure of the idler 14 and the driving gear 10 is completely consistent, coaxially arranged and separately arranged at the two ends of the supporting frame 6; the transmission mechanism one and The structure of the second transmission mechanism is exactly the same, the first transmission mechanism is located at the end where the support frame 6 is connected to the motor bracket 12, and the second transmission mechanism is located at the end where the support frame 6 is connected to the idler gear 14; both the first transmission mechanism and the second transmission mechanism include driven gears 19. Driven gear 2 11, rack 8, first connecting rod 5, second connecting rod 4 and third connecting rod 3; second connecting rod 4 is Z-shaped, including integrally formed top side rod, middle Rod and bottom side bar; Driven gear one 9 and support frame 6 constitute revolving pair; One end of first connecting rod 5 is fixed with driven gear one 9, and the pin shaft that is hinged at the other end of first connecting rod 5 and the middle rod offer The chute forms a rolling friction pair; the bottom side bar and the slide rail fixed on the support frame 6 form a sliding pair; the third connecting rod 3 is located below the top side bar, and one end is hinged with the rack 8; one side of the driven gear 11 is connected to the The rack 8 meshes; the slideway of the rack 8 and the support frame 6 constitutes a sliding pair; the other side of the driven gear 11 of the transmission mechanism 1 and the side of the driven gear 1 9 are respectively meshed with the two sides of the driving gear 10; the transmission mechanism Two driven gear two 11 other sides and driven gear one 9 one side and idler gear 14 both sides mesh respectively. The driven gear 2 11 of the transmission mechanism 1 and the transmission mechanism 2 is fixed on the two ends of the transmission shaft 7, and the transmission shaft 7 is supported on the support frame 6 through bearings.

The number of teeth of driving gear 10 and idler gear 14 is identical, and is all less than the number of teeth of driven gear two 11, and the number of teeth of driven gear two 11 is less than the number of teeth of driven gear one 9.

The rack 8, the top side bar and the bottom side bar are all set horizontally; the middle bar is vertically set, and the chute of the middle bar is also vertically set.

As shown in Figure 1, Figure 2 and Figure 4, the working principle of the automatic push-out and flip-up reset mechanism is as follows:

The support frame is connected with the inside of the furniture box 2 by bolts, the top side bars of the second connecting rod 4 in the transmission mechanism 1 and the transmission mechanism 2 are all hinged with the control panel 1, and the third connecting rod 3 of the transmission mechanism 1 and the transmission mechanism 2 The other ends are all hinged with the control panel 1; the hinge center position of the third link 3 and the control panel 1 is lower than the hinge center of the top side bar and the control panel 1; the first link, the second link, the third link, The rack and the control panel together form a five-bar mechanism. The driving motor 13 forwardly rotates to drive the driving gear 10 to rotate, the driven gear 1 9 and the driven gear 2 11 of the transmission mechanism 1 are all meshed with the driving gear 10 for transmission, and the driven gear 2 11 of the transmission mechanism 1 drives the transmission mechanism through the transmission shaft 7 The second driven gear 2 rotates; in the transmission mechanism 1 or transmission mechanism 2, the driven gear 1 9 rotates to drive the first connecting rod 5 to slide upward in the chute of the second connecting rod 4 so as to drive the second connecting rod 4 to the furniture The outside of the box is promoted, and the driven gear 2 11 rotates to drive the rack 8 to drive outside the furniture box, and the rack 8 drives the third connecting rod 3 to push together to the outside of the furniture box. When the first connecting rod 5 moves to the horizontal limit position, the driving motor 13 is self-locking; at this time, because the top side bar of the second connecting rod 4 is hinged with the upper part of the control panel 1, the third connecting rod 3 is hinged with the lower part of the control panel 1 , and the second connecting rod 4 is equal to the rod length of the first connecting rod 5 relative to the outward moving distance of the furniture box, and the outer moving distance of the tooth bar 8 relative to the furniture box (equal to the pitch curve displacement of the driven gear-9, also can be from The pitch curve total displacement of moving gear 2 11) is greater than the bar length of the first connecting rod 5, and finally the third connecting rod 3 realizes the rolling-out movement of the control panel 1, and the control panel 1 is fixed at the turning angle at this moment to facilitate user operation. To reset the control panel 1, it is only necessary to reverse the drive motor 13, which is the reverse process of the upward movement of the control panel 1; when the control panel 1 is reset, the drive motor 13 is self-locked again, and the first connecting rod 5 moves to the vertical Straight to the bottom limit position. Since the utility model adopts gear transmission, the opening and closing action of the control panel 1 is stable, reliable, and noiseless, thereby improving customer experience and comfort.

In Fig. 4, after the control panel 1 is overturned, the hinge center position of the top side bar of the second link 4 and the control panel 1 is point A, the hinge center position of the third link 3 and the control panel 1 is point B, and the third The hinge center position of the connecting rod 3 and the rack 8 is point C, and the hinge center position of the first connecting rod 5 and the pin shaft is point D; The hinge center position of the third link 3 and the control panel 1 is point B', the hinge center position of the third link 3 and the rack 8 is point C', the first link 5 The hinged center position with the pin is point D'.
