That is, in this embodiment, the unlocking member 40 is indirectly driven to rotate the first handle 20 to realize the electric brake release.

In this manner, the end of the second handle 60 near the unlocking element 40 may be correspondingly provided with a column member (i.e. the action bar 90 in the foregoing description), so that the second driving element of the unlocking element 40 may drive the column member to rotate the second handle 60, thereby driving the first handle 20 to rotate.

In this embodiment, the principle of the electric opening and closing of the transmission mechanism is as follows:

electric closing: the motor 11 drives the gear set 12 to rotate, the first sector tooth 121 of the gear set 12 drives the second sector tooth 21 of the first handle 20 to rotate, and the first handle 20 drives the contact mechanism 30 to move through the second connecting rod 82, so that the contact mechanism 30 is connected, as shown in fig. 2 and 3;

electric brake separating: when the contact mechanism 30 is in the connection state (as shown in fig. 3), at this time, the motor 11 drives the gear set 12 to rotate (the rotation direction is the same as the rotation direction during closing), the shift lever 13 on the gear set 12 rotates synchronously, the shift lever 13 can push the first driving lever 42 of the unlocking member 40 to rotate, so that the first driving lever 42 drives the second driving lever 43 to rotate simultaneously through the body 41, at this time, the bending part of the second driving lever 43 can shift the action lever 90 of the second handle 60 to rotate the second handle 60, at this time, the second handle 60 drives the first handle 20 to rotate through the first connecting rod 81, and thus, the first handle 20 drives the contact mechanism 30 to disconnect through the second connecting rod 82.

When the lever 13 drives the first driving lever 42 to rotate, the second driving lever 43 may drive the second handle 60 to indirectly drive the first handle 20 to rotate, or may directly drive the first handle 20 to rotate. The above manner of indirectly driving the first handle 20 by driving the second handle 60 is only one example given in the present application, and is not a limitation of the present application, and a person skilled in the art may select an appropriate manner according to the need.

For example, when the lever 13 drives the first driving lever 42 to rotate, the second driving lever 43 may directly drive the first handle 20 to rotate.

At this time, as shown in fig. 7 to 10, the trip member 40 may alternatively include a body 41 rotatably coupled to the housing 70 and a first driving lever 42 and/or a second driving lever 43 fixedly coupled to the body 41, respectively; the electric assembly 10 further comprises a deflector rod 13, the deflector rod 13 and the first sector gear 121 are arranged in a stacked mode, one end of the deflector rod 13 is fixedly connected with the rotation center of the first sector gear 121 of the electric assembly 10, and the other end of the deflector rod is used for pushing the first driving rod 42 to rotate; the first handle 20 is provided with a convex column 22; when the contact mechanism 30 is in the connected state, the shift lever 13 pushes the first driving lever 42 to rotate, and the second driving lever 43 can push the convex column 22 to rotate so as to drive the first handle 20 to rotate, so that the contact mechanism 30 is disconnected.

In this manner, the boss 22 is provided on the first handle 20, so that when the contact mechanism 30 is in the connected state, the driving lever 13 pushes the first driving lever 42 to rotate, and the second driving lever 43 can push the boss 22 to rotate to drive the first handle 20 to rotate, so that the contact mechanism 30 is disconnected.

In this embodiment, when the lever 13 pushes the first driving lever 42 to rotate, the second driving lever 43 can directly act on the boss 22 on the first handle 20 (in this embodiment, the boss 22 and the first handle 20 may be an integral part), so that the first handle 20 rotates to drive the contact mechanism 30 to disconnect, as shown in fig. 8 and 9. This is a simpler transmission than the indirect driving of the first handle 20 by driving the second handle 60 as described above.

In this embodiment, the principle of the electric opening and closing of the transmission mechanism is as follows:

electric closing: the motor 11 drives the gear set 12 to rotate, the first sector tooth 121 of the gear set 12 drives the second sector tooth 21 of the first handle 20 to rotate, and the first handle 20 drives the contact mechanism 30 to move through the second connecting rod 82, so that the contact mechanism 30 is connected, as shown in fig. 7 and 8;

electric brake separating: when the contact mechanism 30 is in the connection state (as shown in fig. 8), at this time, the motor 11 drives the gear set 12 to rotate (the rotation direction is the same as that of the switch-on), the shift lever 13 on the gear set 12 rotates synchronously, and the shift lever 13 can push the first driving lever 42 of the unlocking member 40 to rotate, so that the first driving lever 42 drives the second driving lever 43 to rotate simultaneously through the body 41, at this time, the second driving lever 43 drives the first handle 20 to rotate by pulling the boss 22 on the first handle 20 (as shown in fig. 9), and thus, the first handle 20 drives the contact mechanism 30 to disconnect through the second connecting rod 82, as shown in fig. 7.

Referring to fig. 7, 8 and 10, the transmission mechanism optionally further includes a first limiting member 71 fixed on the housing 70 (specifically, the lower housing), where the first limiting member 71 is located on a side of the second driving rod 43 away from the first driving rod 42 and is used for limiting the second driving rod 43.

The first limiting piece 71 is arranged to limit the rotation angle of the unlocking piece 40 within a certain range, so that the situation that the shift lever 13 cannot act on the first driving lever 42 when the first limiting piece 71 deflects at the position before opening the brake is avoided.

It should be noted that, the setting position of the first limiting member 71 should be based on the fact that when the motor 11 drives the lever 13 to rotate through the gear set 12, the sweeping area of the lever 13 can act on the first driving lever 42 of the unlocking member 40.

It should be noted that, when the lever 13 drives the first driving lever 42, the unlocking member 40 may enable the second driving lever 43 to act on the second handle 60 or the boss 22.

Optionally, the transmission mechanism may further include a second limiting member 72 disposed on the housing 70 (specifically, the upper housing), where the second limiting member 72 and the orthographic projection of the first limiting member 71 on the housing 70 are disposed at intervals, and the second limiting member 72 is located on a side of the second driving rod 43 away from the first driving rod 42 and is used for limiting the second driving rod 43.

The arrangement position and arrangement requirement of the second stopper 72 are the same as those of the first stopper 71, and the description thereof will not be repeated here.

In this embodiment, the housing 70 includes an upper housing and a lower housing that are fastened to each other, and the first limiting member 71 is disposed on the lower housing and extends toward the upper housing; and the second limiting member 72 is disposed on the upper housing and extends toward the lower housing.

In this embodiment, the orthographic projections of the first stopper 71 and the second stopper 72 on the housing 70 (specifically, the upper housing or the lower housing) are disposed at intervals, so that the two stoppers can cooperate with each other, thereby improving the reliability of the stoppers.
