[0030] Please refer to Figures 1 - 6, the present utility model provides a refrigerator 100, which includes a box body 10, a box door, a push rod assembly 20 and a cover 30. The box body 10 includes a main body 11 and a bottom plate 12. The bottom plate 12 is connected to the bottom end of the main body 11. The bottom plate 12 and the main body 11 cooperate to form a chamber. An installation groove 121 is formed on the bottom plate 12; the box door is connected to the box body 10, and the front side of the box body 10 where the box body 10 is connected to the box door is the front side. A through hole 122 is opened on the front side of the bottom plate 12; the push rod assembly 20 is arranged in the installation groove 121, and a part of the push rod assembly 20 can extend out from the through hole 122; the cover 30 covers the notch of the installation groove 121 and separates the installation groove 121 from the chamber. In this way, since the push rod assembly 20 is arranged in the installation groove 121 on the bottom plate 12 and can extend out from the through hole 122 opened on the front side of the box body 10, the push rod assembly 20 can push the box door to realize the function of automatic door opening. The cover 30 covers the notch of the installation groove 121 and cooperates with the groove wall of the installation groove 121 to form a sealed space. Therefore, it can protect the push rod assembly 20 installed therein. When the foaming process is carried out in the chamber, it is ensured that the foaming material will not affect the push rod assembly 20 to ensure the stable operation of the push rod assembly 20.

[0031] Further, the bottom plate 12 is recessed along the direction away from the chamber to form the installation groove 121. Therefore, the installation groove 121 is formed by the bottom plate 12 through processes such as bending or stamping, without the need to additionally add other structures, saving material costs and simplifying the processing steps.

[0032] Of course, in other embodiments, the installation groove 121 can also be directly opened on the bottom plate 12 instead of being formed by its bending. Or, a through groove is opened on the bottom plate 12, and then a bottom groove structure is welded, which can also realize the above-mentioned installation groove 121 structure.

[0033] The push rod assembly 20 includes a push rod 21 and a driving source 22. The push rod 21 is connected to the driving source 22, and the axis of the push rod 21 and the axis of the driving source 22 are arranged at an angle. In this way, the driving source 22 is used to provide the driving force for the push rod 21 to extend. The push rod 21 can extend or retract along its axial direction, so as to realize the opening and closing of the box door. And because the thickness space in the front and rear directions of the box body 10 is limited, the push rod 21 and the driving source 22 are arranged at an angle, which can reduce the space occupied by the two in the horizontal direction in the front and rear of the box body 10, so that there is more space inside the refrigerator 100 to arrange other components.

[0034] Further, the push rod assembly 20 further includes a first fixing member 23 and a second fixing member 24. The first fixing member 23 and the second fixing member 24 are respectively connected to two ends of the push rod 21 in the axial direction, and both the first fixing member 23 and the second fixing member 24 are connected to the bottom of the installation groove 121. In this way, the push rod assembly 20 is fixedly connected to the bottom plate 12 through the first fixing member 23 and the second fixing member 24, ensuring that it will not shift in position during the process of extending or retracting. The first fixing member 23 and the second fixing member 24 are arranged at both ends thereof, and the two ends in its length direction can also be subjected to a limiting force, further ensuring the connection strength between it and the bottom plate 12 (i.e., the bottom of the installation groove 121).

[0035] It can be understood that in other embodiments, the push rod assembly 20 can also be directly welded or bonded to the bottom of the installation groove 121, and is not limited to being installed and fixed through the first fixing member 23 and the second fixing member 24.

[0036] Furthermore, the first fixing member 23 includes a first fixing portion 231 and a first connecting portion 232. A first installation opening (not shown in the figure) is provided on the first fixing portion 231, and the push rod 21 passes through the first installation opening. The first connecting portion 232 has two and is respectively connected to the radial two sides of the fixing portion, and both the two first connecting portions 232 are connected to the bottom of the installation groove 121. In this way, the first installation opening on the first fixing portion 231 and the push rod 21 form a circumferential limiting abutment, thereby improving the connection strength between the first fixing portion 231 and the push rod 21, and the two first connecting portions 232 improve the connection strength between the first fixing portion 231 and the bottom of the installation groove 121. The two force application points are arranged at intervals, making the force on the first fixing portion 231 and the bottom of the installation groove 121 more balanced.

[0037] Furthermore, two first installation seats 123 are arranged in the installation groove 121. The two first installation seats 123 are connected to the bottom of the installation groove 121, and both the two first installation seats 123 protrude towards the push rod assembly 20 with first installation columns 1231. Two first installation holes 2321 are provided on the first connecting portion 232, and the first installation columns 1231 and the first installation holes 2321 are correspondingly clamped. In this way, the first connecting portion 232 and the first installation seat 123 achieve plug-in cooperation, which is more convenient for disassembly and assembly and has a good limiting effect.

[0038] Specifically, the first installation seat 123 further includes an installation base 1232. The installation base 1232 is connected to the first installation column 1231, and the diameter of the installation base 1232 is larger than that of the first installation column 1231. In this way, the connection area between the installation base 1232 and the bottom of the installation groove 121 is large, and the connection strength it can provide to the first installation seat 123 is higher. The first installation column 1231 is connected to the side of the installation base 1232 facing away from the bottom of the installation groove 121 to achieve connection with the first connecting portion 232.

[0039] The second fixing member 24 includes a second fixing portion 241 and a second connecting portion 242. The second fixing portion 241 is connected to the second connecting portion 242, and the second fixing portion 241 is connected to the end of the push rod 21 away from the first fixing member 23. In this way, the second fixing member 24 fixes the end of the push rod 21 away from the first fixing member 23 to the bottom of the mounting groove 121. The second fixing portion 241 is specifically used to connect with the push rod 21 and, as a transition member, realizes fixed limit through the second connecting portion 242.

[0040] A second mounting seat 124 is arranged in the mounting groove 121. The second mounting seat 124 is connected to the bottom of the mounting groove 121, and the second mounting seat 124 protrudes a second mounting post 1241 towards the push rod assembly 20. A second mounting hole 2421 is formed in the second connecting portion 242, and the second mounting post 1241 and the second mounting hole 2421 are correspondingly clamped. In this way, the assembly and disassembly of the second mounting seat 124 and the second connecting portion 242 are more convenient, and the circumferential abutting connection method can provide higher connection strength.

[0041] Specifically, in this embodiment, a fixing groove 2411 is further formed in the second fixing portion 241, and the second connecting portion 242 is embedded in the fixing groove 2411. And the edge of the opening of the fixing groove 2411 in the horizontal direction is converged, so that the second connecting portion 242 is stably arranged in the fixing groove 2411 to ensure that the second connecting portion 242 will not escape from the fixing groove 2411.

[0042] The refrigerator 100 further includes a base 40. The base 40 is connected to the bottom plate 12, and an avoidance hole 41 coaxial with the through hole 122 is formed in the front side of the base 40, so that the push rod 21 can smoothly extend out and abut against the door. An avoidance groove 42 is formed in the base 40, and the position of the avoidance groove 42 corresponds to the position of the mounting groove 121 in the vertical direction, making the arrangement of the push rod assembly 20 more convenient. After the avoidance groove 42 sinks, the distance between it and the bottom of the mounting groove 121 increases, thus providing a higher foaming space.

[0043] The base 40 and the bottom plate 12 are arranged at intervals, and a foaming space is formed between them. Foaming between the base 40 and the bottom plate 12 can further improve the heat preservation effect of the refrigerator 100.

[0044] Preferably, the distance between the lowest point of the bottom plate 12 close to the base 40 and the bottom of the avoidance groove 42 is at least 53 mm. Thereby ensuring the foaming thickness and the heat preservation effect at this position. At the same time, the depth of the avoidance groove 42 is set to be more than 12 mm, which is beneficial to the heat dissipation at the bottom of the refrigerator 100.

[0045] In addition, a wire outlet hole is formed in the groove wall of the installation groove 121 for the circuit wiring of the push rod assembly 20. Before foaming, in this embodiment, the driving source 22 is a motor. The motor terminal is inserted and stuffed into the installation groove 121 through this wire outlet. The outside is sealed with tape or aluminum foil to prevent the foaming agent from infiltrating, while protecting and sealing the motor terminal, eliminating the terminal fixing before foaming and the avoidance design of the foaming mold.

[0046] Compared with the prior art, in the present utility model, the installation groove 121 is formed by the downward depression of the bottom plate 12. The push rod assembly 20 for automatically opening and closing the door of the refrigerator 100 is arranged in the installation groove 121, and the push rod assembly 20 installed therein is protected by the protective cover 30. When the foaming process is carried out in the chamber, it is ensured that the foaming material will not affect the push rod assembly 20 to ensure the stable operation of the push rod assembly 20.

[0047] The technical features of the above-described embodiments can be combined arbitrarily.
