Description

Technical Field

[0001] The utility model relates to the technical field of electric drying racks, in particular to a braking structure for a driving assembly of a drying rack and an electric drying rack with a high braking structure. Background Art

[0002] In the existing electric lifting drying racks, the lifting of the drying rod is controlled by a lifting driving assembly. Generally, a braking mechanism is not provided on the dual-axis motor used in the existing driving assembly of the electric drying rack. After the drying rod rises or falls to a certain position, if the clothes on the drying rod are heavy, due to the action of gravity, the drying rod will continue to descend. Therefore, most existing manufacturers will design corresponding locking structures, which lock when the drying rod rises or falls to a certain fixed position. However, such locking structures are complex, with high manufacturing costs, and are prone to jamming during actual use. Moreover, the locked position is fixed and cannot be adjusted flexibly. Summary of the Utility Model

[0003] Aiming at the above problems, the utility model provides a braking structure for a driving assembly of a drying rack and an electric drying rack with a high braking structure, which has a simple structure, low manufacturing cost, and flexible adjustment.

[0004] The utility model is realized by the following technical solutions:

[0005] A braking structure for a driving assembly of a drying rack includes a dual-axis driving motor and a bearing rotatably connected to the output shaft of the dual-axis driving motor. A braking mechanism capable of reducing the rotation speed of the bearing is rotatably connected to the output shaft of the dual-axis driving motor. The braking mechanism includes a braking ring, which is rotatably connected to the output shaft and fixed to the bearing. The friction force between the braking ring and the output shaft is greater than the friction force between the outer ring and the inner ring of the bearing.

[0006] To ensure the braking effect, the braking mechanism further includes a locking member. An annular clamping portion capable of clamping the output shaft is integrally formed on one side end face of the braking ring. The clamping portion has a notch. The locking member is sleeved on the clamping portion and can lock the clamping portion and the output shaft to increase the friction force between the braking ring and the output shaft.

[0007] Preferably, the locking member is a ring-shaped spring connected end to end.

[0008] To facilitate the installation and fixation of the braking ring and the bearing, the other end face of the braking ring away from the clamping portion is fixed to the end face of the bearing with glue.

[0009] In a preferred embodiment of the present utility model, a braking mechanism is provided on one of the bearings on the output shaft of the dual-axis drive motor; and in order to further improve the braking effect, the braking mechanism can also be provided on both bearings.

[0010] The present utility model also provides an electric drying rack, and the above-mentioned braking structure of the drying rack drive assembly is installed on the electric drying rack.

[0011] The beneficial effects of the present utility model are as follows: The braking structure of the drying rack drive assembly and the electric drying rack add a braking mechanism to the original drive assembly. The braking mechanism can provide a certain resistance to the lifting and lowering of the drying rod. After the drying rod is lifted and lowered in place, due to the resistance, the drying rod will not lift and lower again without external force, thus playing a braking role. The lifting and braking position can be adjusted according to the actual situation, which is flexible and convenient. Description of the Drawings
