[0002] At present, more and more door products on the market have cancelled the traditional door handle design for the sake of panel aesthetics, so that users cannot open the door with the door handle. Instead, an automatic door push structure is introduced to push the door open to a certain angle to facilitate users to open the door. However, for household cabinets and other furniture, their volume is often large. For aesthetics and storage convenience, the automatic door push device is usually installed on the top of the cabinet. In this way, how to trigger the automatic door push device to achieve the purpose of user opening the door has become a difficult problem. Summary of the invention

[0027] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0028] Embodiment 1

[0029] like Figures 1 to 4 As shown, this embodiment provides an automatic door-pushing device, which includes a door-body sensing mechanism disposed on the cabinet door 2 and a cabinet-body 1 driving control mechanism disposed on the cabinet body 1 .

[0030] like Figure 1 , 2 As shown, the door body sensing mechanism includes a knock sensing area 21 and a sensor 3, both of which are arranged in the middle right area of ​​the cabinet door 2 to facilitate the user to knock. The knock sensing area 21 is arranged on the front of the cabinet door 2, and the knock sensing area 21 is used for the user to knock. The sensor 3 is arranged on the back of the cabinet door 2 and corresponds to the knock sensing area 21, and the sensor 3 is used to sense the user's knocking signal.

[0031] like Figure 1 , 2 As shown, the cabinet 1 driving control mechanism includes a control module 6 and a door-pushing assembly 7. The sensor 3 sends a knocking signal to the control module 6 via wireless communication. The door-pushing assembly 7 is used to drive the cabinet door 2 to move. The control module 6 is used to control the extension and retraction of the door-pushing assembly 7 according to the knocking signal.

[0032] When the user wants to open the cabinet door 2, he knocks on the knock sensing area 21 on the front of the cabinet door 2, and the sensor 3 on the back of the cabinet door 2 senses the vibration signal, and transmits the vibration signal to the control module 6 on the cabinet body 1 through wireless transmission. Figure 4As shown, the door push assembly 7 is controlled to push the cabinet door 2 a certain distance, and even if the cabinet door 2 has no handle, the user can easily open the cabinet door 2. If the user taps the cabinet door 2 to push it open for a period of time, but does not manually open the cabinet door 2, the cabinet door 2 will automatically close under the action of the hinge as the door push assembly 7 is retracted.

[0033] like Figure 1 , 2 As shown, the automatic door pushing device of this embodiment also includes a door body charging mechanism 5, which is arranged on the back of the cabinet door 2, and the door body charging mechanism 5 is arranged on the top of the back of the cabinet door 2. The control module 6 is arranged on the top of the cabinet 1. When the cabinet door 2 is closed, the control module 6 supplies power to the sensor 3 through the door body charging mechanism 5.

[0034] like Figure 1 , 2 As shown in Figure 3, the control module 6 of this embodiment includes a charging contact device 61 and a main circuit board. The charging contact device 61 is electrically connected to the main circuit board, and the main circuit board is electrically connected to the door push assembly 7. When the cabinet door 2 is closed, the charging contact device 61 transmits electrical energy to the door charging mechanism 5 to power the sensor 3. When the cabinet door 2 is opened, the charging contact device 61 is separated from the door charging mechanism 5, and the sensor 3 cannot be powered by wireless charging or contact charging. In this case, the module cannot sense knocking when the power is off, thus avoiding user error triggering. Figure 8 As shown, the main circuit board of this embodiment includes an MCU module, a wireless communication module, a motor control module and a power supply module. The charging contact device 61, the wireless communication module and the motor control module are all connected to the MCU module. The MCU module controls the extension and retraction of the sliding door assembly 7 through the motor control module, and the external 220V AC power is used to power the main board and the charging contact device 61 through the power supply module.

[0035] like Figure 1 As shown, the back of the cabinet door 2 of this embodiment is provided with an installation slot, and the sensor 3 is arranged in the installation slot. The sensor 3 includes a sensing circuit board, on which a vibration sensing sensor is arranged. The vibration sensing sensor of this embodiment adopts a piezoelectric vibration sensor, which is used to collect the knocking signal of the user. The sensing circuit board communicates wirelessly with the main circuit board. Fig. 9As shown, the sensing circuit board of this embodiment also includes an MCU module, a power module and a wireless communication module. The door body charging mechanism 5 supplies power to the sensing circuit board through the power module. The vibration sensing sensor and the wireless communication module are both connected to the MCU module. The MCU module receives the user knocking signal collected by the vibration sensing sensor, and then communicates wirelessly with the wireless communication module on the main circuit board through the wireless communication module. The wireless communication module of this embodiment is preferably a Bluetooth module. After receiving the user knocking signal, the MCU module on the main circuit board controls the door pushing assembly 7.

[0036] like Figure 1 , 3 As shown, the door charging mechanism 5 of this embodiment is a receiving coil, which is electrically connected to the inductor 3; the charging contact device 61 is a charging coil, which is arranged at the top of the back of the cabinet door 2, and the charging coil is arranged at the top of the cabinet body 1. When the cabinet door 2 is closed, the charging coil generates current in the receiving coil by wireless charging. The inductor 3 on the back of the cabinet door 2 is electrically connected to the receiving coil through the cable 4. When the cabinet door 2 is closed, the receiving coil fits with the charging coil on the cabinet body 1, so that the control module 6 can generate current in the receiving coil by wireless charging, thereby powering the inductor 3 and ensuring that the inductor 3 can work normally. When the cabinet door 2 is opened, the receiving coil and the charging coil are separated, and the power supply of the inductor 3 is disconnected.

[0037] like Figure 7 As shown, the door push assembly 7 of this embodiment includes a motor 71, a worm 72, a worm wheel 73, a gear pair 74 and a rack push rod 75. The worm 72 is arranged on the shaft of the motor 71, and the worm 72 is meshed with the worm wheel 73. When the motor 71 rotates, the coaxial gear at the bottom of the worm wheel 73 drives the rack push rod 75 to extend and retract through the gear pair 74.

[0038] Embodiment 2

[0039] like Figure 5 , 6 As shown, this embodiment provides another implementation of the door charging mechanism 5 and the charging contact device 61. In this embodiment, the door charging mechanism 5 is a receiving probe, and the receiving probe is electrically connected to the sensor 3. The charging contact device 61 is a charging probe, and the receiving probe is arranged at the top of the back of the cabinet door 2, and the charging probe is arranged at the top of the cabinet 1. When the cabinet door 2 is closed, the charging probe is electrically connected to the receiving probe. The sensor 3 module on the back of the cabinet door 2 is connected to the receiving probe through a cable 4. When the cabinet door 2 is closed, the receiving probe is attached to the charging probe on the cabinet 1 to complete the electrical connection, so that the control module 6 can supply power to the sensor 3 to ensure that the sensor 3 can work normally. When the cabinet door 2 is opened, the receiving probe and the charging probe are separated, and the power supply of the sensor 3 is disconnected.
