Description

Technical Field

[0001] The utility model belongs to the technical field of lifting devices, and in particular relates to a lifting drive device. Background Art

[0002] Nowadays, people's demands for home living are becoming increasingly demanding, and renovations must consider not only aesthetics but also practicality. For bathroom furniture, such as cabinets and mirrors, the traditional installation method involves fixing them to the wall at a standard height. This height is suitable for people of standard height, but for those with disabilities, such as the elderly, the weak, or the disabled, this height becomes an obstacle. Whether in public or at home, bathroom furniture is used by a diverse demographic, representing a one-to-many product. Because the height of bathroom furniture cannot be adjusted after installation, the traditional installation height inevitably restricts its use for these individuals.

[0003] Therefore, some liftable bathroom furniture has emerged in the prior art to meet the needs of different groups of people. For example, prior art CN217827212U discloses a hidden, electrically liftable mirror cabinet, which belongs to the field of mirror cabinets and includes a bottomless mirror cabinet body. Two center panels are connected between the top of the inner wall and the rear end surface of the inner wall of the bottomless mirror cabinet. The two center panels are connected to the opposite sides of the inner wall of the bottomless mirror cabinet. The two horizontal panels are respectively connected to the two sides of the inner wall of the bottomless mirror cabinet. Two sliding mechanisms are provided at the lower part of the rear end surface of the inner wall of the bottomless mirror cabinet. The bottomless mirror cabinet body has no bottom panel design, and a lifting space is reserved for a lifting drawer. When the lifter is opened, the lifting drawer is vertically lifted to adjust the storage height. Then, multiple acrylic storage pieces are pushed according to usage needs, so that the positions of the multiple acrylic storage pieces can also be adjusted horizontally according to usage needs, thereby allowing the storage height of the mirror cabinet to be adjusted, thereby improving the practicality and flexibility of the mirror cabinet and facilitating its use by users.

[0004] However, existing bathroom furniture lifting devices typically utilize a lever that moves up and down or telescopically. This approach is difficult to apply to applications requiring a large travel distance and a low height. Furthermore, the lifting device must be stored, and in many cases, there is insufficient space to accommodate it. As a skilled artisan, improvements are necessary. Utility Model Content

DETAILED DESCRIPTION

[0023] like Figure 1-Figure 4 As shown, this embodiment provides a lifting drive device, which is mainly used in smart homes to realize the lifting function of smart homes. The lifting drive device includes a support base 1, a rigid chain 2, and a drive mechanism. The support base 1 is provided with an active channel adapted to the rigid chain 2. The support base 1 is provided with an output port for the lifting and lowering movement of the rigid chain 2. For lifting objects that need to be lifted upward, the output port is provided at the top of the support base 1; for lifting objects that need to be lifted downward, the output port is provided at the bottom of the support base 1. One end of the rigid chain 2 is the lifting end, and the other end of the rigid chain 2 is the horizontal end. The lifting end of the rigid chain 2 passes through the output port and is connected to the lifting object. The lifting object is driven to perform lifting and lowering movements by the movement of the rigid chain 2 in the active channel.

[0024] A drive sprocket 3, which meshes with the rigid chain 2 and rotates within the support base 1, is in transmission connection with the drive mechanism. A guide is provided on one side of the drive sprocket 3. A curved guide bar 4 is provided on the side of the guide bar near the drive sprocket 3. The curved guide bar 4 is used to guide the lifting end of the rigid chain 2 as it moves up and down at the output port. The drive mechanism rotates the drive sprocket 3, which in turn drives the rigid chain 2 to move. With the cooperation of the guide, the lifting end of the rigid chain 2 moves up and down, carrying the object being lifted.

[0025] This utility model innovatively adopts a chain transmission structure in smart homes, which has significant advantages such as compact structure, small size, light weight, smooth lifting, stable structure, and long stroke. It can multiply the lifting range of the lifted object and is particularly suitable for use in some occasions where the lifting stroke requirements are large and the installation height space is small.

[0026] Specifically, the driving mechanism includes a driving member and a transmission assembly, and the driving member is connected to the driving sprocket 3 through the transmission assembly.

[0030] like Figure 2 As shown, in one embodiment, the lifting drive device further includes a protective cover 14, which is sleeved onto the outside of the support base 1. The protective cover 14 has a rectangular structure, and components such as the support base 1, the driving gear 5, the transmission gear 6, and the driven gear 7 are concealed within the protective cover 14. Preferably, the protective cover 14 is provided with a positioning seat 15 adapted to the mounting head 13. When the lifting drive device is lowered to the lowest point, the mounting head 13 contacts the positioning seat 15, improving the stability of the lifted object.

[0031] The rigid chain is a special chain that has the flexibility of an ordinary chain and the rigidity of a jack. The utility model utilizes a driving mechanism to drive the driving sprocket 3 to rotate, and the teeth of the driving sprocket 3 engage with the pin of the rigid chain, pushing the chain units of the rigid chain to move upward one by one. When each chain unit enters a vertical position, it engages with the chain unit of the previous section to form a chain column with a certain rigidity, which pushes the lifted objects to rise and acts as a jack; when the driving sprocket 3 rotates in the opposite direction, the rigid chain moves in the opposite direction, and the chain units of the rigid chain move downward one by one, and the lifted objects descend.
