The present invention proposes a connector assembly 50, which is applied to a fan oscillating mechanism 100.
Referring to fig. 1 to 3 and fig. 6, in an embodiment of the fan oscillating mechanism 100 of the present invention, the connector assembly 50 includes:
a connector 51, wherein the connector 51 is provided with a plurality of positioning grooves 511;
the positioning sleeve 53 is rotatably connected with the connector 51, one end of the positioning sleeve 53 is inserted into the connector 51, and the positioning sleeve 53 is provided with a positioning protrusion 531 which is matched with the positioning groove 511 and used for preventing the connector 51 and the positioning sleeve 53 from freely rotating;
the positioning sleeve 53 rotates relative to the connector 51, and the positioning protrusion 531 is sequentially retained in each positioning groove 511.
The fan oscillating mechanism 100 comprises a head assembly 10, a transmission assembly 30 and a connector assembly 50, wherein the head assembly 10 is rotatably arranged on the connector assembly 50, the transmission assembly 30 comprises a connecting rod 31 and a crank 33, one end of the connecting rod 31 is connected with a positioning sleeve 53 in the connector assembly 50, and the other end of the connecting rod is connected with an output shaft of an oscillating driving motor 11 in the head assembly 10 through the crank 33. When the head shaking driving motor 11 operates, the four-bar linkage formed by the head assembly 10, the transmission assembly 30 and the connector assembly 50 starts to move, and at this time, the head assembly 10 rotates relative to the connector assembly 50 under the driving of the transmission assembly 30, so as to realize the head shaking function.
In this embodiment, the positioning sleeve 53 is a cylindrical structure with two open ends, and extends in the vertical direction. The oscillating rotation shaft 13 of the head assembly 10 is also extended in the vertical direction, is inserted into the positioning sleeve 53, and is rotatable relative to the positioning sleeve 53. At this time, the lower end of the positioning sleeve 53 is inserted into the connector 51 and is rotatable relative to the connector 51.
Further, the positioning grooves 511 on the connecting head 51 are arranged along an arc, and the center of the arc is located on the rotation center of the positioning sleeve 53, in other words, the positioning grooves 511 on the connecting head 51 are arranged along the circumferential direction of the positioning sleeve 53. Specifically, when the head assembly 10 rotates relative to the connector assembly 50, the oscillating shaft 13 in the head assembly 10 rotates relative to the positioning sleeve 53 in the positioning sleeve 53, and at this time, the positioning protrusion 531 on the positioning sleeve 53 is accommodated and clamped in the positioning groove 511, so as to fix the positioning sleeve 53 circumferentially, and make the positioning sleeve 53 stationary (not rotate) relative to the connector 51, and the positioning sleeve 53 plays a supporting role on the head assembly 10. When the head shaking angle of the head assembly 10 needs to be adjusted, the fan head shaking mechanism 100 stops running, and an external force acts on the positioning sleeve 53 to rotate relative to the connector 51, at this time, the positioning protrusion 531 on the positioning sleeve 53 also rotates along with the positioning sleeve 53, and the positioning protrusion 531 passes over the barrier between two adjacent positioning grooves 511, slides from one positioning groove 511 to the other positioning groove 511 and is clamped in the positioning groove 511, so that the positioning sleeve 53 rotates at a certain angle. That is, compared with the positioning protrusion 531 being received and retained in the upper positioning groove 511, at this time, the positioning sleeve 53 rotates at a certain angle relative to the connector 51, the connecting rod connection point on the positioning sleeve 53 also rotates at a certain angle relative to the connector 51, and the related included angle in the four-bar structure also changes at a certain angle, so as to adjust the oscillating angle of the fan. Moreover, it should be noted that the positioning grooves 511 may enable the fan to have a plurality of selectable oscillating angles, so as to better meet the use requirements of users.
Therefore, it can be understood that in the technical solution of the present invention, by providing the positioning groove 511 on the connector 51, providing the positioning protrusion 531 on the positioning sleeve 53, and when the positioning sleeve 53 rotates relative to the connector 51, the positioning protrusion 531 is sequentially clamped in each positioning groove 511, so that positioning and fixing when the positioning sleeve 53 rotates to different positions can be achieved, and adjustment of different positions of the connecting rod connection on the positioning sleeve 53 can be achieved, and selection of multiple oscillating angles of the fan can be achieved. Compared with the existing structure, the fan oscillating mechanism has the advantages that the use of parts such as springs and positioning nails is avoided, the number of parts of the fan oscillating mechanism 100 is reduced, the assembly difficulty is reduced, the assembly efficiency is improved, and meanwhile, the material cost is reduced. Moreover, it can be appreciated that the positioning protrusion 531 and the positioning grooves 511 are matched, and the modular pre-assembly can be performed during the assembly, so that the manpower resources are saved, the manpower cost is reduced, and the practicability is improved.
Referring to fig. 4, a receiving groove 513 is formed on a surface of the connecting head 51 facing the positioning sleeve 53, and a plurality of positioning grooves 511 are formed on a sidewall of the receiving groove 513. Thus, the engagement of the positioning protrusion 531 with the positioning grooves 511 can be performed and completed in the accommodating groove 513. On one hand, the accommodating groove 513 can protect the positioning protrusion 531 and the positioning grooves 511, so that the matching of the positioning protrusion 531 and the positioning grooves 511 is prevented from being interfered by the outside, and the normal and effective matching of the positioning protrusions 531 and the positioning grooves 511 is ensured; on the other hand, the positioning protrusion 531 and the positioning grooves 511 are disposed in the accommodating groove 513, so that the height of the connector assembly 50 can be effectively reduced, and the stability of the connector assembly in cooperation with other assemblies can be improved.
As shown in fig. 4, the side wall of the accommodating groove 513 further has at least one stop portion 515 protruding therefrom, the stop portion 515 is disposed along the arrangement direction of the positioning groove 511, and the stop portion 515 is disposed outside the positioning groove 511.
In this embodiment, the connector 51 includes two stopping portions 515, and the two stopping portions 515 clamp the positioning grooves 511, i.e. the positioning grooves 511 are located between the two stopping portions 515. It can be appreciated that the setting of the stop portion 515 can effectively limit the rotation angle of the positioning protrusion 531, prevent the positioning protrusion 531 from separating from the positioning grooves 511, and avoid the damage of the related structure caused by the large-angle rotation of the positioning sleeve 53, thereby effectively ensuring the structural integrity of the fan oscillating mechanism 100, ensuring the cooperation of the positioning protrusion 531 and the positioning grooves 511, and ensuring that the oscillating angle of the fan can be effectively adjusted.
As shown in fig. 4, the connector 51 is provided with a sleeve 517 toward the positioning sleeve 53, and an end of the positioning sleeve 53 toward the connector 51 is rotatably inserted into the sleeve 517.
In this embodiment, the sleeve 517 is disposed in the accommodating groove 513 and extends in a vertical direction, and the inner wall of the sleeve 517 is substantially cylindrical, at this time, the positioning grooves 511 are arranged along an arc, and the center of the arc is located on the axis of the sleeve 517, in other words, the positioning grooves 511 on the connector 51 are arranged along the circumferential direction of the sleeve 517. The lower end of the positioning sleeve 53 is also substantially cylindrical and is inserted into the sleeve 517 and rotatable relative to the sleeve 517. Thus, the positioning sleeve 53 and the connector 51 can be rotationally connected, the structure is simple, the assembly is convenient, and the material is saved.
Referring to fig. 5, the positioning sleeve 53 further has a holding groove 533 facing the sleeve 517, and a portion of the sidewall of the sleeve 517 is received in the holding groove 533.
Specifically, the outer side of the side wall at the lower end of the positioning sleeve 53 is further provided with a clamping wall 535, the clamping wall 535 and the side wall at the lower end of the positioning sleeve 53 are arranged at intervals, the clamping wall 535 extends along the circumference of the lower end of the positioning sleeve 53 and forms an arc-shaped clamping groove 533 together with the side wall at the lower end of the positioning sleeve 53, and when the lower end of the positioning sleeve 53 is inserted into the sleeve 517, part of the side wall of the sleeve 517 is accommodated and clamped in the arc-shaped clamping groove 533, so that the connection stability of the positioning sleeve 53 and the connector 51 is effectively enhanced.
As shown in fig. 5, the positioning sleeve 53 is provided with an elastic member 537 facing one of the positioning grooves 511, and the free end of the elastic member 537 is provided with the positioning protrusion 531.
In this embodiment, the elastic member 537 has two opposite ends, one of which is fixed to the holding wall 535, and the other of which is far away from the holding wall 535 and faces the positioning groove 511, and one end (free end) of the elastic member 537 far away from the holding wall 535 faces the positioning groove 511 and is further provided with a positioning protrusion 531 protruding toward the positioning groove 511, and the positioning protrusion 531 is accommodated in and held by the positioning groove 511.
It will be appreciated that during rotation of the positioning sleeve 53, the positioning protrusion 531 will slide from one positioning groove 511 to another positioning groove 511 across the barrier between adjacent positioning grooves 511. At this time, the elastic piece 537 can effectively buffer the extrusion between the positioning protrusion 531 and the barrier, and avoid the deformation of the positioning protrusion 531 and the positioning groove 511, thereby ensuring the cooperation of the positioning protrusion 531 and the positioning grooves 511, ensuring the effective adjustment of the oscillating angle of the fan, and prolonging the service life of the structure. Meanwhile, when the positioning protrusion 531 is accommodated and clamped in the positioning groove 511, the elastic member 537 can provide sufficient supporting force for the positioning protrusion 531, so that the stability of the positioning protrusion 531 clamped in the positioning groove 511 is effectively improved, the positioning fixing effect of the connector 51 on the circumferential direction of the positioning sleeve 53 is more stable, and adverse effects on related structures caused by accidental rotation of the positioning sleeve 53 are avoided.
Specifically, the elastic member 537 is a U-shaped elastic member, one end of the U-shaped elastic member is fixed, and the other end thereof is provided with the positioning protrusion 531. Therefore, the structure is simple, reliable and effective, the manufacture is convenient and fast, the assembly efficiency is high,
