Referring to fig. 1 to 4, the present invention provides a driving apparatus 100 for an automatic door, including a motor assembly 10, a sensor 20 electrically connected to an external controller (not shown), and a connecting assembly 30 fixedly connected to the automatic door (not shown); the motor assembly 10 comprises a motor 11 and a speed reducer 12 fixedly connected with the motor 11, a rotating shaft 121 is arranged on the speed reducer 12, a circular gear 122 is arranged on the rotating shaft 121, and a plurality of first teeth 1221 are formed on the surface of the outer ring of the gear 122 in a protruding mode.

One end of the connecting assembly 30 close to the motor assembly 10 is fixedly connected with an oval-shaped matching cover 40, a first abutting part 41 and a second abutting part 42 which is opposite to the first abutting part 41 in interval are convexly formed on the outer wall of the matching cover 40, and the first abutting part 41 and the second abutting part 42 are distributed along the long axis of the matching cover 40; a plurality of second teeth 43 corresponding to the plurality of first teeth 1221 are formed to protrude from an inner wall of the fitting cover 40, and the plurality of second teeth 43 are located between the first abutting portion 41 and the second abutting portion 42.

The sensor 20 is mounted on the speed reducer 12 of the motor assembly 10 and is spaced from the gear 122; the mating cover 40 covers the gear 122, the first abutting portion 41 is disposed near the sensor 20, and the first teeth 1221 of the gear 122 are engaged with the second teeth 43 of the mating cover 40. In the present embodiment, the sensor 20 is a piezoresistive sensor; the connection assembly 30 is made of steel.

When the motor 11 of the motor assembly 10 is started and drives the rotating shaft 121 of the speed reducer 12 to rotate along the first direction, the gear 122 on the rotating shaft 121 rotates along with the rotating shaft 121 and drives the matching cover 40 and the connecting assembly 30 on the connecting assembly 30 to rotate along the first direction by 15 degrees to 90 degrees (because the matching cover 40 is oval, the gear 122 is circular), the speed reducer 12 can reduce the driving force of the motor 11 so that the first teeth 1221 of the gear 122 can be gradually separated from the second teeth 43 of the matching cover 40, the first abutting part 41 gradually keeps away from the sensor 20 along with the rotation of the matching cover 40, and the gear 122 drives the matching cover 40 and the connecting assembly 30 to rotate so as to enable the automatic door to be in an open state (namely, the rotating angle range of the automatic door is 15 degrees to 90 degrees). When the first teeth 1221 of the gear 122 are disengaged from the second teeth 43 of the mating cover 40, the mating cover 40 cannot rotate with the gear 122 (in this case, the rotating shaft 121 and the gear 122 are in a state of rotating).

When the motor 11 of the motor assembly 10 is started and drives the rotating shaft 121 of the speed reducer 12 to rotate along the second direction, the gear 122 on the rotating shaft 121 rotates along with the rotating shaft 121 and drives the matching cover 40 and the connecting assembly 30 on the connecting assembly 30 to rotate along the second direction by 15 degrees to 90 degrees, the speed reducer 12 reduces the driving force of the motor 11 so that the first teeth 1221 of the gear 122 are gradually re-meshed with the second teeth 43 of the matching cover 40, the first abutting part 41 is gradually close to the sensor 20 along with the rotation of the matching cover 40 and abuts against the sensor 20, and the automatic door is in a closed state by rotating the matching cover 40 and the connecting assembly 30. When the first abutting portion 41 abuts against the sensor 20 along with the rotation of the mating cover 40, the sensor 20 sends an electrical signal to an external controller, and the external controller receives the electrical signal and sends a command to stop the operation of the motor 11 of the motor assembly 10, so that the gear 122 stops rotating.

Therefore, the rotating shaft 121 drives the gear 122 to rotate, so that the gear 122 drives the matching cover 40 to rotate, the connecting assembly 30 rotates along with the matching cover 40 and drives the automatic door to rotate, and the connecting assembly 30 is made of steel, so that the connecting assembly has enough strength, can bear larger acting force and is not easy to damage; the automatic door is stopped at a preset position by the mutual engagement and disengagement of the first teeth 1221 of the gear 122 and the second teeth 43 of the matching cover 40, so that the situation that the automatic door is not closed is avoided; it is also possible to control the start and stop of the motor 11 by the first abutment 41 of the cooperating cap 40 coming into contact with the sensor 20.

It should be noted that, the first direction is a clockwise direction, and the second direction is a counterclockwise direction; the end surfaces of the first tooth 1221 and the second tooth 43 are both arc-shaped.

In one embodiment, the rotating shaft 121 is cylindrical and passes through the middle of the gear 122, and the rotating shaft 121 and the gear 122 are arranged in a concentric circle.

In one embodiment, the sensor 20 includes a main body 21 having a rectangular parallelepiped shape, a contact spring piece 211 is disposed on a side of the main body 21 close to the gear 122, and the first abutting portion 41 can abut against the contact spring piece 211 of the main body 21 along with the rotation of the mating cover 40. When the contact spring piece 211 of the sensor 20 is deformed by an external force, the resistance value of the sensor 20 changes and sends an electrical signal to an external controller, and the external controller receives the electrical signal and sends an instruction to stop the operation of the motor 11 of the motor assembly 10.

In one embodiment, a plurality of pins 212 are further disposed on a side of the body 21 of the sensor 20 away from the gear 122, and the sensor 20 is electrically connected to an external controller through the plurality of pins 212.

In one embodiment, the main body 21 includes a mounting surface 210, the contact spring piece 211 is "V" shaped and includes a first section 2111 fixed on the mounting surface 210 of the main body 21 and a second section 2112 connected to the first section 2111, and the second section 2112 is inclined relative to the mounting surface 210 to form an included angle a.

When the gear 122 drives the matching cover 40 and the connecting rod 31 to rotate, the fixed base plate 32 rotates along with the connecting rod 31, so that the automatic door installed on the fixed base plate 32 rotates along with the fixed base plate 32, and the automatic door is opened or closed. Specifically, the connecting rod 31, the fixing base plate 32 and the matching cover 40 of the connecting assembly 30 are all made of steel, so that the connecting rod 31, the fixing base plate 32 and the matching cover 40 have enough strength, can bear large acting force and are not easy to damage.

In one embodiment, the fixed bottom plate 32 is sleeved on the outer wall of the connecting rod 31.

In one embodiment, a notch 401 is formed on a side of the mating shell 40 away from the motor 11 of the motor assembly 10; the first abutting portion 41 gradually moves away from the sensor 20 with the rotation of the mating cap 40, and the first tooth 1221 of the gear 122 gradually disengages from the second tooth 43 on the side of the mating cap 40 away from the notch 401; the first abutting portion 41 gradually abuts against the contact spring piece 211 of the sensor 20 along with the rotation of the mating cover 40, and the first tooth 1221 of the gear 122 gradually engages with the second tooth 43 on the side of the mating cover 40 away from the notch 401. In this way, the movement state of the gear 122 can be observed through the notch 401, and lubricating oil can be added to the gear 122 through the notch 401, so that the possibility that the first tooth 1221 of the gear 122 and the second tooth 43 of the mating cover are abraded is reduced.

In one embodiment, the driving device 100 further includes a mounting plate 50 mounted on the speed reducer 12 of the motor assembly 10, and the sensor 20 is mounted on the mounting plate 50.

In one embodiment, the mounting plate 50 defines an opening 51 for mounting the sensor 20, and the sensor 20 is mounted in the opening 51. In this way, the contact area between the sensor 20 and the mounting plate 50 can be increased, and the sensor 20 can be securely mounted in the opening 51 of the mounting plate 50, thereby preventing the sensor 20 from being displaced.
