The term "and / or" used in the specification of this application includes any and all combinations of one or more related listed items.

[0029] See also Figures 1 to 7 The present application provides a push rod assembly 100, which is installed on the lower base 200 of the refrigerator. The push rod assembly 100 includes a positioning member 20 and a connecting member 30, which are located at two opposite ends of the push rod assembly 100. The lower base 200 is provided with a positioning groove 210 and a connecting position 220, and the positioning groove 210 and the connecting position 220 are arranged at intervals along a first direction X. Among them, the positioning member 20 can be inserted into the positioning groove 210 along the first direction X, and the connecting member 30 can be detachably connected to the connecting position 220 from the first direction X. In the process of actually installing the push rod assembly 100, the first direction X is configured as a horizontal direction, the positioning member 20 of the push rod assembly 100 is first inserted horizontally into the positioning groove 210, and then the connecting member 30 is connected to the connecting position 220 from the horizontal direction, so that the push rod assembly 100 is firmly connected to the lower base 200. In this way, the push rod assembly 100 can be installed horizontally, which is more convenient to operate. In addition, the positioning member 20 cooperates with the positioning groove 210 to play a role in positioning and pre-installation, and can quickly guide the push rod assembly 100 to be placed in the desired position, thereby helping to improve the installation efficiency of the push rod assembly 100.

[0030] like Figure 6 As shown, the push rod assembly 100 also includes a main shell 10, a motor 40 and a push rod 50, wherein the positioning member 20 and the connecting member 30 are respectively located at two ends of the main shell 10, the motor 40 is located on the side of the main shell 10, one end of the push rod 50 is connected to the motor 40, and the other end is movably arranged in the main shell 10, and the motor 40 can drive the push rod 50 to extend in a direction away from the main shell 10 so as to push open the door of the refrigerator.

[0031] See also Figure 4 The positioning member 20 has a first surface 21 and a second surface 22, and the first surface 21 and the second surface 22 are respectively used to fit the groove wall of the positioning groove 210, and the first surface 21 is parallel to the first direction X, and the second surface 22 is inclined relative to the first direction X. It can be understood that, by the first surface 21 and the second surface 22 respectively fitting the groove wall of the positioning groove 210, the positioning member 20 can only be inserted into the positioning groove 210 at a specific angle, and cannot be inserted into the positioning groove 210 along other angles.

[0032] Optionally, in one embodiment, along the second direction Y, the second surface 22 is located below the first surface 21, and the second surface 22 and the first surface 21 form a triangular structure, wherein the second direction Y is perpendicular to the first direction X. In this way, the positioning member 20 can only be installed in the positioning groove 210 at an angle with the second surface 22 facing downward.

[0033] In another embodiment, the second surface 22 may be located above the first surface 21 along the second direction Y. Alternatively, in another embodiment, the second surface 22 may be located on the left or right side of the first surface 21 along the second direction Y.

[0034] For example, in one embodiment, Figure 6 As shown, the positioning member 20 includes an L-shaped plate 23 and a triangular support plate 24, one end plate of the L-shaped plate 23 is connected to the main housing 10, the other end plate forms the first surface 21, the triangular support plate 24 is connected between the two end plates of the L-shaped plate 23, and the outer end surface of the triangular support plate 24 forms the second surface 22. It should be noted that the "outer end surface of the triangular support plate 24" refers to the surface of the two end plates of the triangular support plate 24 away from the L-shaped plate 23. In this embodiment, the triangular support plate 24 is not only used to form the second surface 22, but also can support the L-shaped plate 23, thereby improving the structural strength of the positioning member 20.

[0035] Specifically, the L-shaped plate 23 is connected to the main housing 10 by screw threads. The number of the triangular support plates 24 is configured to be multiple, and the multiple triangular support plates 24 are arranged between the two end plates of the L-shaped plate 23 at intervals.

[0036] See also Figure 5 and Figure 6 The connecting member 30 includes a mounting portion 31 and a plurality of connecting portions 32. The mounting portion 31 is sleeved on the outer circumference of the main housing 10. The connecting portion 32 is used to connect to the connecting position 220, and the plurality of connecting portions 32 are distributed at intervals along the circumference of the mounting portion 31. In this way, the connecting member 30 and the main housing 10 are easily assembled, and the connecting member 30 and the connecting position 220 are firmly connected.

[0037] Furthermore, the connection portion 32 is used to fit the connection position 220 along the first direction X, and each connection portion 32 is provided with a mounting hole 321, and the mounting hole 321 is used for fasteners to pass through. Specifically, the fasteners can be configured as screws, the connection portion 32 and the connection position 220 are arranged vertically, and the connection portion 32 and the connection position 220 are fitted together along the horizontal direction, and the screws pass through the mounting hole 321 horizontally and thread the connection portion 32 to the connection position 220.

[0038] Please refer again Figures 1 to 7 The present application also provides a push rod assembly installation structure 1, which includes a lower base 200, an air duct 300 and the push rod assembly 100 described in any one of the above embodiments. The lower base 200 and the air duct 300 enclose an assembly cavity 400, and the positioning groove 210 and the connecting position 220 are arranged on the side of the lower base 200 close to the assembly cavity 400. The assembly cavity 400 has an opening 410, and the push rod assembly 100 can be installed in the assembly cavity 400 along the first direction X through the opening 410. Among them, the lower base 200 is a supporting structure at the bottom of the refrigerator, and the air duct 300 is used for heat dissipation at the bottom of the refrigerator. By installing the push rod assembly 100 in the assembly cavity 400 formed by the lower base 200 and the air duct 300, there is no need to set an additional installation box outside the push rod assembly 100, which is conducive to saving material costs.

[0039] Specifically, a protrusion 240 is disposed on the side of the lower base 200 close to the assembly cavity 400 , the positioning groove 210 is opened on the protrusion 240 , and the connection position 220 is configured as a stud.

[0040] The push rod assembly mounting structure 1 further includes a cover plate 500, which is detachably mounted on the opening 410. The cover plate 500 is used to shield and decorate the opening 410.

[0041] Optionally, in one embodiment, if Figure 1 and Figure 7 As shown, the cover plate 500 is provided with a plurality of buckles 510, and the lower base 200 is provided with a slot 230 corresponding to the buckles 510, and the buckles 510 are engaged with the slot 230. Of course, in other embodiments, the cover plate 500 can also be connected to the lower base 200 by screws.

[0042] The present application also provides a refrigerator, which includes the push rod assembly mounting structure 1 described in any one of the above embodiments.
