Example 1

Referring to fig. 1 to 6, a motor mounting assembly of a motorized window treatment includes a driving part 1 and a transmitting part 2, wherein the driving part 1 includes a motor 11 and an end cover 12 provided at an axial end of the motor 11, and the motor 11 has an output shaft 111. The transmission part 2 comprises a transmission case 21 and a transmission wheel 22, the transmission wheel 22 being in transmission connection with the output shaft 111, so that the torque of the output shaft 111 can be transmitted to an external load.

The end cover 12 includes a cover body 121 and a first connection portion 122 formed on the cover body 121, and the transmission case 21 includes a case body 211 and a second connection portion 212 formed on the case body 211, and detachable connection is achieved between the cover body 121 and the case body 211 through the first connection portion 122 and the second connection portion 212 described above. The cover 121 is provided with a connecting hole 123, the connecting hole 123 is preferably cylindrical, the first connecting portion 122 is configured as a first rotating fixture block formed on an inner peripheral wall of the connecting hole 123, and the first connecting portion 122 is arc-shaped. The output shaft 111 described above penetrates into the connection hole 123 and is located radially inward of the first connection portion 122. The second connecting portion 212 is configured as a second rotating block protruding from the side of the case 211 facing the driving portion 1, and the second connecting portion 212 is also arc-shaped. The housing 211 is hollow, and the driving wheel 22 extends partially out of the housing 211 to be connected with the output shaft 111, and partially can be positioned in the housing 211.

When the drive unit 1 and the transmission unit 2 are connected, the first connection unit 122 and the second connection unit 212 are aligned, and are displaced in both the axial direction (the axial direction of the motor 11) and the circumferential direction (the circumferential direction of the motor 11), and the drive unit 1 or the transmission unit 2 is rotated around the axial direction of the motor 11, so that the first connection unit 122 and the second connection unit 212 overlap at least partially in the circumferential direction, and at this time, engagement is enabled due to the axial displacement of the two connection units, thereby defining the axial positions of the drive unit 1 and the transmission unit 2. A positioning boss 124 may be provided at one circumferential end of the first connection portion 122 or the second connection portion 212 to limit the rotation angle required for the two connection portions to rotate in place. Taking the example of providing the positioning boss 124 on the first connecting portion 122, in the initial state where the two connecting portions are completely displaced in the circumferential direction, the positioning boss 124 is located at one end of the first connecting portion 122 away from the second connecting portion 212 in the circumferential direction. The two connection parts are turned from the fully displaced initial state to the turned-in position, preferably by 90 °. Alternatively, the first connecting portion 122 may be provided at any position so long as the first connecting portion 122 and the second connecting portion 212 can be rotatably engaged. The connection structure of the first connection portion 121 and the second connection portion 122 is the same as that of the prior art, and will not be described herein.

However, even if the positioning boss 124 is provided, positioning cannot be completed, that is, one of the driving part 1 and the transmitting part 2 is rotated in the reverse direction, so that the first connecting part 122 and the second connecting part 212 are disengaged. Therefore, a locking structure is also required.

The locking structure includes a pressing plate 213 provided on one of the cover 121 and the case 211 and a locking groove 125 provided on the other of the cover 121 and the case 211, so that the driving part 1 and the transmitting part 2 are locked in the circumferential direction by the locking of the pressing plate 213 and the locking groove 125. Wherein the pressing plate 213 is provided as a first member, in this embodiment a housing 211, and the locking groove 125 (and the transition groove 126 hereinafter) is provided as a second member, in this embodiment a cover 121.

The pressing plate 213 is provided on a side of the case 211 facing the driving part 1, and includes a plate 2131, a button 2132 provided on the plate 2131, and a lock block 2133 provided on the plate 2131, and both the button 2132 and the lock block 2133 protrude toward the driving part 1. The plate 2131 and the case 211 are integrally formed, and the plate 2131 is formed by grooving the case 211 toward the driving unit 1 (the outer periphery of the plate 2131 surrounds the groove, and a portion of the plate 2131 is connected to the case 211). Thus, the case 211 can be integrally molded by injection molding, and the operation of the pressing plate 213 can be realized by utilizing the elasticity of the plastic material itself without providing an additional operating mechanism.

The locking groove 125 is preferably provided at a position near the edge of the cover 121, and the button 2132 corresponds to the outside of the cover 121, i.e., the projection of the button 2132 in the radial direction of the motor 11 falls outside the projection of the cover 121 in the radial direction of the motor 11, and the button 2132 is not subjected to the force of the cover 121 after the installation process or installation is completed. A transition groove 126 may be provided in the cover 121, which may receive the locking block 2133 in an initial state. The locking groove 125 and the transition groove 126 are each formed by recessing the cover 121 toward the case 211 and away from the case 211.

The lock block 2133 has two surfaces facing each other in the circumferential direction, namely a lock surface 2134 extending in the axial direction of the motor 11 and a transition surface 2135 extending obliquely in the axial direction of the motor 11, and the transition surface 2135 is gradually inclined toward the lock surface 2134 from the pressing plate 2131 toward the end cover 12. When the lock block 2133 is in the transition groove 126, its transition face 2135 faces the lock groove 125.

The plate body 2131 of the pressing plate 213 is provided with a reinforcing rib 2136 on the side facing the inside of the case 211 to avoid breakage of the pressing plate 213. The locking blocks 2133 and the reinforcing ribs 2136 are provided on opposite sides of the plate 2131, respectively.

When the driving unit 1 and the transmission unit 2 are in the initial state, the end face of the cover 121 and the end face of the case 211 are bonded, and the lock block 2133 is accommodated in the transition groove 126. When the driving portion 1 and the transmission portion 2 rotate relatively, the first connecting portion 121 and the second connecting portion 212 gradually overlap and are engaged, and due to the arrangement of the transition surface 2135, the locking block 2133 can be easily separated from the transition groove 126, and the locking block 2133 corresponds to the solid portion of the cover 121 between the locking groove 125 and the transition groove 126, so that the cover is squeezed, and the pressing plate 213 deforms and is integrally pressed into the box 211. When the driving part 1 and the transmission part 2 are rotated in place, the locking block 2133 is rotated to a position aligned with the locking groove 125, and is thereby elastically returned by the pressing plate 213 itself to be automatically inserted into the locking groove 125, thereby locking is completed, and the locking surface 2134 is an axially vertical surface, so that the driving part 1 and the transmission part 2 can be further prevented from being reversely rotated.

When the driving unit 1 and the transmitting unit 2 are to be detached, the driving unit 1 or the transmitting unit 2 may be reversely rotated by pressing the button 2132 to disengage the lock block 2133 from the lock groove 125.

With this structure of the present embodiment, the pressing plate 213 for locking is provided on the transmission case 21, reducing the structural complexity of the driving part 1, making the assembly of the driving part 1 simpler. Compared with the traditional complex locking structure requiring elastic components, locking blocks, operation parts and the like, the pressing plate 213 only needs to be integrally formed by the transmission case 21, and the structure is simpler, the assembly is not needed, and the cost is lower by utilizing the elasticity of plastic materials.

Example two

Referring to fig. 7 and 8, in the present embodiment, the difference from the first embodiment described above is that the transition groove 126 is not provided, and the shape of the locking groove 125 is adapted to the shape of the locking block 2133, i.e., the bottom surface (the surface away from the locking block 2133) of the locking groove 125 is an inclined surface adapted to the transition surface 2135 of the locking block 2133. The locking block 2133 may be similarly arc-shaped, and its central angle is the same as the rotation angle of the driving part 1 and the transmission part 2.

In the initial state of installation, the end cap 12 needs to be attached to the transmission case 21 with force, so that the lock block 2133 is pressed by the cover 121 and deformed into the case 211. The rotational connection is then in the same way as in the first embodiment.

Example III

Referring to fig. 9 and 10, in the present embodiment, the difference from the first embodiment described above is that the positions of the locking structures are interchanged, i.e., the locking groove 125 and the transition groove 126 are opened at the side of the case 211 (second member) facing the driving part 1, and the pressing plate 213 is formed at the side of the cover 121 (first member) facing the transmitting part 2. Since the case 211 is generally faced to the side of the cover 121 to cover the side of the cover 121 facing to the case 211, in order to facilitate the operation of the button 2132, the button 2132 extends to the outside in the circumferential direction of the cover 121 and is spaced from the case 211 by a distance greater than the distance between the side of the cover 121 facing to the case 211 and the case 211 so that a finger can be inserted between the button 2132 and the case 211 for a pressing operation.

Likewise, the positions of the locking structures in the second embodiment are also interchangeable.
