[0035] In order to make the technical problems, technical schemes and beneficial effects of the utility model clearer and more apparent, the utility model will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and not to limit the utility model.

[0036] As shown in Figure 1 , 2 The distance adjusting device provided by the utility model can be applied in refrigeration equipment, including but not limited to refrigerators. Specifically, the distance adjusting device comprises a box body 1, a force arm assembly and a power mechanism, the bottom of the box body 1 is provided with a cavity, the force arm assembly is arranged in the cavity at the bottom of the box body 1, the force arm assembly comprises two force arms 2 connected through a hinge, and the power mechanism drives the force arm assembly to unfold or fold.

[0037] When the position of the box body needs to be adjusted, the power mechanism drives the two force arms 2 to unfold to the outside of the box body 1, and the position of the box body 1 is adjusted by controlling the length of the force arms 2 to extend, so as to adapt to different installation environments. When the position of the box body does not need to be adjusted, the power mechanism drives the two force arms 2 to fold to form an air guide baffle, the cavity at the bottom of the box body 1 is divided into two areas by the air guide baffle, the space layout at the bottom of the box body is optimized, especially when the cavity at the bottom of the box body 1 is used as a heat dissipation cavity, the air guide baffle divides the heat dissipation cavity into an air inlet area 11 and an air outlet area 12, air flows from the air inlet area 11 to the air outlet area 12, the air guide baffle separates cold air and hot air, reduces heat exchange between the two, and improves heat dissipation efficiency.

[0038] The utility model adopts the hinge-connected force arm assembly, which can be switched to an unfolded state or a folded state, and in the unfolded state, the force arm assembly extends outside the box body 1, and in the folded state, the force arm assembly forms an air guide baffle, so that the multifunctional design can effectively improve the utilization rate of the distance adjusting device.

[0039] As shown in Figures 3 to 5 In some embodiments, the box body 1 is embedded in the installation area 6, such as the reserved space of a cabinet, to realize seamless connection with the home environment, the front side of the box body 1 is provided with a box door 13, the rear side of the box body 1 is located inside the installation area 6, and the box door 13 faces the outside of the installation area 6, so as to facilitate the user to open or close the box door 13. The two force arms 2 can unfold to the left and right sides of the box body 1, and the end of the force arm 2 abuts against the installation area 6, and the length of the force arm 2 is controlled to push the box body 1 to move left and right until reaching a suitable installation position.

[0040] On this basis, the bottom of the box body 1 is provided with a heat dissipation cavity, the heat dissipation cavity is communicated with the external environment of the mounting area 6, for example, a refrigerator and the like refrigeration equipment, the heat generating components such as compressor, condenser are usually installed at the bottom of the box body 1, the heat dissipation cavity helps the refrigerator to release heat during operation, so that the refrigerator runs stably. The two force arms 2 can be folded to form a guide air baffle perpendicular to the cabinet door 13, which divides the heat dissipation cavity into left and right two areas, which are the air inlet area 11 and the air outlet area 12 respectively, and the guide air baffle is provided with a guide air gap with the rear side of the box body 1 to ensure that the air can flow smoothly. This design cleverly combines the guide air baffle and the heat dissipation cavity, when the refrigerator is working, the external air can flow into the air inlet area 11 to dissipate heat for the heat generating components, the hot air after heat dissipation passes through the guide air gap and is discharged outward from the air outlet area 12, the airflow in the heat dissipation cavity is stable and orderly, the heat dissipation effect is improved, which is helpful for the long-term stable operation of the refrigerator.

[0041] In the preferred embodiment of the utility model, the distance adjusting device further comprises: a distance measuring device and a controller, the distance measuring device is installed on the left and right sides of the box body 1 or the middle position of the force arm assembly, and the function is to detect the distance between the box body and the mounting area 6, and the distance measuring device can use existing distance measuring devices such as laser ranging, ultrasonic ranging or infrared ranging. The controller is the core of the distance adjusting device, which is connected with the distance measuring device and the power mechanism, the distance measuring device sends the detection data to the controller, and the controller receives the detection data and adjusts the working state of the force arm assembly through the power mechanism.

[0042] Specifically, the controller switches the force arm assembly to the unfolded state when the actual distance corresponding to the detection data deviates from the preset distance. In actual use, the technician can calculate the length of the force arm extending out of the box body 1 according to the size of the mounting area 6 and the box body 1, and set the unfolded state of the force arm assembly. When the box body 1 is initially installed, the power mechanism drives the force arm assembly to reach the unfolded state, so that the box body 1 is in a suitable installation position. When the left or right side of the box body 1 deviates, the power mechanism drives the force arm assembly to reach the unfolded state, so that the box body 1 returns to the suitable installation position, ensuring the consistency of the installation gap.

[0043] As shown in Figure 3 During the installation or adjustment of the position of the box body 1, the end of the force arm 2 extends out of the box body 1 and abuts against the side wall of the mounting area 6. Since the cabinet body of the cabinet is usually made of wood or other materials, the end of the force arm 2 may scratch the cabinet body and the friction force is too large when it closely contacts the cabinet body. In order to improve the adjustment quality of the position of the box body, the end of the force arm 2 is provided with a roller 3. After the force arm assembly is unfolded, the roller 3 rolls in contact with the side wall of the mounting area 6, avoiding scratching the wall surface of the mounting area 6, and the box body 1 can move normally, facilitating installation.

[0044] As shown in Figure 3As shown, in some feasible embodiments of the present invention, two force arms 2 are arranged up and down, and the middle position of the two force arms 2 is hingedly connected, which is equivalent to having four force arms that can be unfolded and extended to the outside of the box. After unfolding, a more balanced thrust can be provided, thereby enhancing the stability of the movement of the box 1 and avoiding the deflection of the box 1.

[0045] The power mechanism mentioned above can be designed according to specific needs, and the present invention does not impose any special restrictions on this. For ease of understanding, some feasible solutions are provided below for illustration.

[0046] like Figure 6 、 7 As shown, in some embodiments, the power mechanism includes: a drive assembly, each lever arm 2 is equipped with a drive assembly, the function of the drive assembly is to drive the lever arm 2 to rotate, and in actual use, the drive assemblies of the two lever arms 2 work synchronously, so that the lever arms 2 rotate relative to each other to achieve expansion or closure.

[0047] The drive assembly includes a screw 4, a gear 5, and a motor. Screw 4 is hingedly connected to arm 2 and can move along it. The ends of screw 4 are connected to arm 2 via pins, bearings, and other components, allowing screw 4 to slide on arm 2 while maintaining rotational freedom. A guide structure, such as a track or chute, is provided between the ends of screw 4 and arm 2 to ensure smooth movement. Screw 4 meshes with gear 5. Rotation of gear 5 drives screw 4 linearly, which in turn drives arm 2 to rotate, allowing it to expand or close.

[0048] Specifically, when the electric component drives the gear 5 to rotate, the gear 5 drives the screw 4 to move horizontally. If the screw 4 moves in the direction away from the other lever arm 2, the lever arm 2 follows the screw 4 to rotate in the direction away from the other lever arm 2 until it reaches the expanded state; if the screw 4 moves in the direction close to the other lever arm 2, the lever arm 2 follows the screw 4 to rotate in the direction close to the other lever arm 2 until it reaches the closed state.

[0049] like Figures 3 to 5 As shown, the present invention also provides a refrigerator having the aforementioned distance adjustment device. The refrigerator includes a compressor, a condenser, a throttling device, and an evaporator, which are sequentially connected to form a refrigerant circulation loop. The evaporator supplies cold air to the refrigerator compartment. During cooling operation, the refrigerant discharged from the compressor flows sequentially through the condenser, the throttling device, and the evaporator before returning to the suction side of the compressor.

[0050] In actual use, technicians can calculate the length of the lever arm 2 extending from the box body 1 in advance based on the dimensions of the installation area 6 and the box body 1, and thereby set the expanded state of the lever arm assembly, that is, add an installation mode or a fixed mode to the distance adjustment device used in the refrigerator.

[0051] When the refrigerator is initially installed, the installation mode is started, the force arm assembly is switched to the unfolded state, and the end of the force arm 2 is tightly attached to the side wall of the cabinet during the process of pushing the refrigerator into the cabinet, preventing the refrigerator from shaking left and right when moving, and always maintaining the proper installation position.

[0052] After the refrigerator is installed, the user will apply a left-right horizontal force to the refrigerator while opening the door during use, which will change the gap between the refrigerator and the cabinet over a long period of time, thereby affecting the user's door opening angle and the aesthetic appearance of the embedded refrigerator. When the cabinet 1 is offset to the left or right, the fixed mode is started, the force arm assembly is switched to the unfolded state, and is tightly attached to the cabinet, so that the cabinet 1 returns to the proper installation position, ensuring the consistency of the installation gap.

[0053] In the structure of the refrigerator, the compressor and the condenser are usually installed at the bottom of the refrigerator. The bottom of the cabinet 1 of the refrigerator is provided with a heat dissipation cavity for discharging heat generated during operation of the refrigerator. The air guide partition plate separates the heat dissipation cavity into an air inlet area 11 and an air outlet area 12, effectively optimizing the heat dissipation effect of the refrigerator.

[0054] Specifically, when the condenser fan of the refrigerator is turned on, air will be sucked from the air inlet area 11, pass through the heat generating components such as the compressor and the condenser, absorb the heat released by the heat generating components, and the temperature of the air will rise. Subsequently, these hot air passes through the air guide gap into the air outlet area 12 and is finally discharged to the outside of the refrigerator, thereby completing the entire heat dissipation cycle. Since the air guide partition plate is separated between the air inlet area 11 and the air outlet area 12, the cold air and the hot air are separated, reducing heat exchange between them, and the airflow in the heat dissipation cavity is more stable and orderly, and the heat dissipation effect is better.

[0055] Since the position of the refrigerator usually does not need to be adjusted frequently, after installation is completed, the force arm assembly is in the folded state for a long time, and the two force arms 2 are used as air guide partition plates to improve the heat dissipation performance of the heat dissipation at the bottom of the refrigerator.
