Detailed Description

Fig. 1 is a schematic structural view of a refrigerator door assembly according to an embodiment of the present invention. Fig. 2 is an exploded schematic view of a refrigerator door assembly according to an embodiment of the present invention. As shown in fig. 1, the present embodiment provides a refrigerator door assembly 100, which may generally include a door liner 10 and a bottle holder 20. The door liner 10 is disposed on an inner side surface of the refrigerator door 200, and includes a first vertical beam 11 and a second vertical beam 12 that extend vertically and are distributed on two lateral sides of the refrigerator door 200. The bottle holder 20 is disposed between the first vertical beam 11 and the second vertical beam 12, and the bottle holder 20 has a first side 21 and a second side 22 facing the first vertical beam 11 and the second vertical beam 12, respectively. As shown in fig. 2, the rotatable gear 30 is disposed on the inner side of each of the first vertical beam 11 and the second vertical beam 12, the first lateral surface 21 and the second lateral surface 22 are respectively provided with a tooth socket 40 matched with the gear 30, and the tooth socket 40 has a plurality of tooth socket teeth 41 vertically distributed and engaged with the gear 30, so that the bottle holder 20 can move in both directions relative to the longitudinal direction of the door liner 10 when the gear 30 rotates in the tooth socket 40.

In the refrigerator door body assembly 100 of the present embodiment, the gear 30 is disposed inside the first vertical beam 11 and the second vertical beam 12 of the door liner 10, the tooth grooves 40 matched with the gear 30 are disposed on both sides of the bottle holder 20, and the bottle holder 20 is driven to move up and down by the rotation of the gear 30 in the tooth grooves 40. This kind of relative motion through 30 tooth's socket 40 of gear realizes the altitude mixture control mode that bottle seat 20 removed, can guarantee that the altitude mixture control of bottle seat 20 both sides is controlled the side step and is transferred unanimously, and the adjustment mode is convenient, swift, simple, can effectively improve user experience.

Further, in the prior art, by means of the height adjustment mode of the groove sliding, sliding friction exists between the bottle seat 20 and the door liner 10, which is easy to cause product loss and affects the service life of the product. Through the connection of the gear 30 tooth grooves 40 of the embodiment, the damage to the product when the bottle seat 20 and the door liner 10 move relatively can be effectively reduced, and the service life is further prolonged.

In one embodiment, as shown in fig. 2, the tooth slot 40 is a long bar shape extending in the vertical direction, and both sides of the tooth slot 40 in the width direction are provided with a plurality of tooth slot teeth 41. In order to achieve the left and right synchronization when the bottle holder 20 moves, the tooth grooves 41 on the tooth grooves 40 on both sides of the bottle holder 20 are usually set to be consistent in specification, and the specifications and initial states of the gears 30 corresponding to both sides of the door liner 10 are also consistent, for example, the tooth pitch and the number of teeth participating in meshing parts are consistent, that is, when the gears 30 rotate, the tooth grooves 40 on both sides can ensure that the rising or falling heights of both sides of the bottle holder are consistent.

Fig. 3 is an enlarged view at a in fig. 2. In another embodiment, as shown in fig. 3, the gear 30 is an under-toothed gear, and a portion of the circumference of the gear 30 is provided with continuous gear teeth 31.

In one embodiment, the gear 30 is configured such that when the gear 30 is engaged with the teeth 41 on one side of the teeth groove 40, the rotation of the gear 30 moves the bottle holder 20 upward, and when the gear 30 is engaged with the teeth 41 on the other side of the teeth groove 40, the rotation of the gear 30 moves the bottle holder 20 downward, so that the rotation of the gear 30 in one direction can move up and down while engaging with the teeth on the different side.

For example, when the gear teeth 31 of the under-toothed gears on both sides of the door liner 10 are engaged with the teeth 41 of the teeth 40 on both sides of the bottle holder 20 on the side close to the refrigerator door 200 in the width direction, the gear 30 moves the bottle holder 20 upward, and when the gear teeth 31 of the under-toothed gears on both sides of the door liner 10 are engaged with the teeth 41 of the teeth 40 on both sides of the bottle holder 20 on the side far from the refrigerator door 200 in the width direction, the gear 30 moves the bottle holder 20 downward. This embodiment is through setting up less tooth gear and tooth's socket 40 ingeniously, can realize the two-way removal of bottle seat 20 through the rotation of less tooth gear along a direction, and operating means is simple, and the effect is better.

In another embodiment, as shown in fig. 2, the refrigerator door assembly 100 further includes a locking structure 50 for positioning the bottle holder 20 when the bottle holder 20 moves to a target height.

Fig. 4 is a schematic structural diagram of a limiting structure according to an embodiment of the invention (positioning groove is not shown). Alternatively, as shown in fig. 4, the locking structure 50 includes a stopper body 51 and a positioning groove 52. The stopper 51 is disposed at the bottle holder 20 and configured to operatively extend or retract at an outer surface of the bottle holder 20. The positioning groove 52 is disposed at the door liner 10 and includes a plurality of vertically distributed notches 521, and when the bottle seat 20 moves to a certain height, the limiting body 51 operatively extends into the notches 521 at the certain height to position the bottle seat 20.

Alternatively, as shown in FIG. 4, the protruding end of the stopper body 51 may be provided in a wedge shape with a gradually decreasing cross-section to be more easily inserted into the notch 521 of the positioning groove 52.

In one embodiment, as shown in FIG. 4, the locking structure 50 further includes an operating lever 53. The operating rod 53 is fixedly connected with the limiting body 51 and is used for providing a force application position for the operation of stretching and contracting the limiting body 51.

In another embodiment, as shown in fig. 4, the locking structure 50 further includes a cartridge seat 54 and a spring 55. The interior of the cartridge seat 54 is provided with a cavity, and the cartridge seat 54 is fixedly connected with the bottle seat 20. One end of the spring 55 is fixedly connected with the box seat 54, and the other end is fixedly connected with the limiting body 51. The spring 55 and at least part of the limiting body 51 are positioned in the cavity, and the operating rod 53 is exposed outside the box seat 54.

When the user moves the bottle seat 20, the operating rod 53 is pulled to enable the limiting body 51 to overcome the acting force of the spring 55 and move to be separated from the positioning groove 52, when the target height required by the user is reached, the operating rod 53 is released, the limiting body 51 is automatically inserted into the positioning groove 52 under the restoring force of the spring 55, then the bottle seat 20 is locked, and the spring 55 is arranged to enable the operation to be simpler and more convenient.

As shown in fig. 4, the operating lever 53 in the above embodiment may be sheet-shaped to facilitate the force application by the user.

Fig. 5 is a schematic structural diagram of a bottle seat and a limiting structure according to an embodiment of the invention. As shown in FIG. 5, in one embodiment, the locking structure 50 is disposed at the bottom of the bottle holder 20. This allows the locking structure 50 to be better hidden, improving the aesthetic appearance of the product. For example, the bottom of the bottle holder 20 may be provided with an opening for placing the cartridge holder 54 so as to hide the cartridge holder and expose only the operating lever 53 (see fig. 5).

As shown in fig. 2, in another embodiment, the refrigerator door assembly 100 includes two sets of locking structures 50, and the stoppers 51 are respectively disposed on two sides of the bottom of the bottle holder 20. Correspondingly, two groups of positioning grooves 52 corresponding to the positions of the limiting bodies 51 are also arranged at the door liner 10. Through setting up two sets of locking structure 50, can make the atress of bottle seat 20 more even, the location is more firm.
