[0001] The present invention relates to the technical field of balance monitoring, and in particular to a balance monitoring device for a refrigerator. Background Art

[0002] With the improvement of people's living standards, the maintenance of various equipment has become increasingly important. For the safety of refrigerators, balance detection technology has been widely used. Therefore, it is very necessary to strengthen the research on balance detection technology. There are means and equipment for balance detection and matters that need to be paid attention to in balance detection, which are not very popular in the market; balance equipment is mainly divided into two categories: soft support balance and hard support balance. It is mainly used for dynamic balance detection and adjustment. There are not many devices for cabinet balance monitoring on the market. The Chinese invention patent application with publication number CN104062073A discloses a dynamic balance detection device. This prior art uses a large number of sensors to measure comprehensive data; however, this prior art cannot realize the automatic docking of refrigerators and automatic balance detection of refrigerators, and its versatility is not strong. Summary of the invention

[0006] Furthermore, the docking mechanism includes a rear frame rotatably mounted on the base frame, a long connecting rod rotatably mounted on the rear frame, the long connecting rod and the transverse connecting rod are rotatably mounted, a middle sliding column is slidably mounted on the rear frame, a connecting frame is fixedly mounted on the middle sliding column, a return spring is arranged between the rear frame and the base frame, a lower clamping block is fixedly mounted on the middle sliding column, a side sliding column is fixedly mounted on the lower clamping block, the side sliding column and the rear frame are slidably mounted, and a side spring is arranged between the lower clamping block and the rear frame.

[0007] The rotation of the travel motor drives the motor bevel gear to rotate, thereby driving the wheel bevel gear and the travel wheel to rotate, so that the base frame moves diagonally toward the refrigerator, and the lower clamping block contacts the two outer walls of the refrigerator that are at right angles to each other. When the contact angle between the lower clamping block and the refrigerator is not correct, the lower clamping block will drive the rear frame to rotate, thereby driving the long connecting rod to rotate, thereby driving the horizontal connecting rod and the rotating wheel frame to rotate, thereby changing the forward direction of the base frame, so that the outer wall of the refrigerator is in contact with the lower clamping block. When the two lower clamping blocks are in contact with the two adjacent outer walls of the refrigerator, the travel wheel continues to move forward, which will drive the lower clamping block to slide toward the rear frame, and the side spring is compressed, thereby driving the connecting frame to slide inward.

[0008] Furthermore, the supporting device includes a lifting motor fixedly mounted on the vertical frame, a vertical screw rod fixedly mounted on the output shaft of the lifting motor, a lifting bevel gear fixedly mounted on the vertical screw rod, a side shaft rotatably mounted on the vertical frame, a side bevel gear and a docking bevel gear fixedly mounted on the side shaft, the side bevel gear is meshed with the lifting bevel gear, a supporting foot is slidably mounted on the vertical frame, the supporting foot and the vertical screw rod form a threaded transmission, and an outward push mechanism is arranged on the base frame.

[0011] Then the lifting motor rotates to drive the vertical screw rod to rotate, thereby driving the support foot to descend along the vertical frame, so that the support foot contacts the ground to provide support for the device. At the same time, the rotation of the vertical screw rod will drive the side bevel gear to rotate through the lifting bevel gear, thereby driving the docking bevel gear to rotate through the side shaft.

[0014] The rotation of the docking bevel gear will drive the docking gear to rotate, thereby driving the screw shaft to rotate, thereby driving the outer slide to slide outward along the connecting plate through the rope slide, the middle slide and the lower slide, thereby driving the upper extrusion plate and the lower extrusion plate to contact and adhere to the outer wall of the refrigerator, and then detecting the balance state of the refrigerator through the position between the sensor and the induction plate. When the refrigerator tilts, the upper extrusion plate will rotate relative to the outer slide or the lower extrusion plate will rotate relative to the outer slide, so that the distance between the induction plate and the sensor will change, and the sensor reading indicates that the refrigerator is in an unbalanced state.

[0015] Compared with the prior art, the present invention has the following advantages: (1) the moving device provided in the present invention can automatically move toward the refrigerator, and after the initial docking, if there is an angle deviation with the outer wall of the refrigerator, it will automatically make fine adjustments to the steering so that the lower clamping block fits with the outer wall of the refrigerator, with high docking accuracy and high intelligence; (2) the supporting device provided in the present invention will be unlocked only after the lower clamping block fits with the outer wall of the refrigerator and is pressed tightly.

[0028] The mobile device is used to approach the refrigerator, the supporting device is used to complete the docking with the refrigerator, and the cabinet clamping device is used to monitor the balance state of the refrigerator.

[0031] The rotation of the travel motor 114 drives the motor bevel gear 115 to rotate, thereby driving the wheel bevel gear 116 and the travel wheel 118 to rotate, so that the base frame 101 moves diagonally toward the refrigerator, and the lower clamping block 104 contacts the two outer walls of the refrigerator that are at right angles to each other. When the contact angle of the lower clamping block 104 and the refrigerator is not correct, the lower clamping block 104 will drive the rear frame 108 to rotate, thereby driving the long connecting rod 111 to rotate, thereby driving the horizontal connecting rod 112 and the rotating wheel frame 113 to rotate, thereby changing the forward direction of the base frame 101, so that the outer wall of the refrigerator is fitted with the lower clamping block 104. When the two lower clamping blocks 104 are fitted with the two adjacent outer walls of the refrigerator, the travel wheel 118 continues to move forward, which will drive the lower clamping block 104 to slide toward the rear frame 108, and the side spring 105 is compressed, thereby driving the connecting frame 110 to slide inward.

[0032] like Figure 5 , Figure 6 As shown, the supporting device includes a lifting motor 201 fixedly mounted on the vertical frame 102, a vertical screw rod 206 is fixedly mounted on the output shaft of the lifting motor 201, a lifting bevel gear 202 is fixedly mounted on the vertical screw rod 206, a side shaft 204 is rotatably mounted on the vertical frame 102, a side bevel gear 203 and a docking bevel gear 205 are fixedly mounted on the side shaft 204, the side bevel gear 203 is meshed with the lifting bevel gear 202, a supporting foot 207 is slidably mounted on the vertical frame 102, the supporting foot 207 and the vertical screw rod 206 form a threaded transmission, and an outward push mechanism is arranged on the base frame 101.

[0033] like Figure 5 , Figure 6 As shown, the push-out mechanism includes a sliding link 209 slidably mounted on the base frame 101, a connecting link 208 is rotatably mounted on the sliding link 209, the connecting link 208 is rotatably mounted with the connecting frame 110, a pulling link 210 is rotatably mounted on the sliding link 209, a sliding frame 211 is rotatably mounted on the pulling link 210, the sliding frame 211 is slidably mounted with the base frame 101, a blocking column 212 is fixedly mounted on the sliding frame 211, the blocking column 212 is slidably mounted with the vertical frame 102, and a tension spring 213 is arranged between the vertical frame 102 and the sliding frame 211.

[0034] The inward sliding of the connecting frame 110 will drive the connecting link 208 to rotate, thereby driving the sliding link 209 to slide on the base frame 101, thereby driving the pulling link 210 to rotate, thereby driving the sliding frame 211 to slide on the base frame 101, thereby driving the blocking column 212 to slide along the vertical frame 102, and the tension spring 213 is stretched, so that the blocking column 212 leaves the bottom of the supporting foot 207, and at this time the lower clamp 104 is just pressed.

[0035] Subsequently, the lifting motor 201 rotates to drive the vertical screw rod 206 to rotate, thereby driving the support leg 207 to descend along the vertical frame 102, so that the support leg 207 contacts the ground to provide support for the device. At the same time, the rotation of the vertical screw rod 206 will drive the side bevel gear 203 to rotate through the lifting bevel gear 202, thereby driving the docking bevel gear 205 to rotate through the side shaft 204.

[0036] like Figure 7-Figure 9 As shown, the clamping cabinet device includes a connecting plate 301 fixedly mounted on the vertical frame 102, a rope slide 302, a middle slide 304 and a lower slide 305 are slidably mounted on the connecting plate 301, an outer slide 303 is fixedly mounted on the rope slide 302, the middle slide 304 and the lower slide 305, a screw shaft 307 is threadedly rotatably mounted on the outer slide 303, a docking gear 306 is fixedly mounted on the screw shaft 307, the docking gear 306 is meshed with the docking bevel gear 205, an upper base plate 308 and a lower base plate 310 are fixedly mounted on the outer slide 303, and an upper extrusion plate 309 and a lower extrusion plate 311 are rotatably mounted on the outer slide 303.

[0037] like Figure 7-Figure 9 As shown, a lower column 312 is slidably installed on the outer slide plate 303, an upper rotating block 314 is fixedly installed on the lower column 312, a lower spring 313 is arranged between the upper rotating block 314 and the outer slide plate 303, a waist hole plate 316 is arranged on the upper extrusion plate 309 and the lower extrusion plate 311, a convex column 315 is fixedly installed on the upper rotating block 314, the convex column 315 slides in the waist hole of the waist hole plate 316, an induction sheet 317 is arranged on the upper extrusion plate 309 and the lower extrusion plate 311, and a sensor 318 is arranged on the upper bottom plate 308 and the lower bottom plate 310.

[0038] The rotation of the docking bevel gear 205 will drive the docking gear 306 to rotate, thereby driving the screw shaft 307 to rotate, thereby driving the outer slide 303 to slide outward along the connecting plate 301 through the rope slide 302, the middle slide 304 and the lower slide 305, thereby driving the upper extrusion plate 309 and the lower extrusion plate 311 to contact and adhere to the outer wall of the refrigerator, and then detect the balance state of the refrigerator through the position between the sensor 318 and the induction plate 317. When the refrigerator is tilted, the upper extrusion plate 309 will rotate relative to the outer slide 303 or the lower extrusion plate 311 will rotate relative to the outer slide 303, so that the distance between the induction plate 317 and the sensor 318 will change, and the reading by the sensor 318 indicates that the refrigerator is in an unbalanced state.

[0039] The working principle of a balance monitoring device for a refrigerator disclosed in the present invention is as follows: the motor bevel gear 115 is driven to rotate by rotating the travel motor 114, thereby driving the bevel gear 116 and the travel wheel 118 to rotate, so that the base frame 101 moves diagonally toward the refrigerator, and the lower clamping block 104 contacts the two outer walls of the refrigerator that are at right angles to each other. When the contact angle between the lower clamping block 104 and the refrigerator is not correct, the lower clamping block 104 will drive the rear frame 108 to rotate, thereby driving the long connecting rod 111 to rotate, thereby driving the horizontal connecting rod 112 and the rotating wheel frame 113 to rotate, thereby changing the forward direction of the base frame 101, so that the outer wall of the refrigerator is fitted with the lower clamping block 104. When the two lower clamping blocks 104 are fitted with the two adjacent outer walls of the refrigerator, the travel wheel 118 continues to move forward, which will drive the lower clamping block 104 to slide toward the rear frame 108, and the side spring 105 is compressed, thereby driving the connecting frame 110 to slide inward. The inward sliding of the connecting frame 110 drives the connecting rod 208 to rotate, thereby driving the sliding rod 209 to slide on the bottom frame 101, thereby driving the pulling rod 210 to rotate, thereby driving the sliding frame 211 to slide on the bottom frame 101, thereby driving the blocking column 212 to slide along the vertical frame 102, and the tension spring 213 is stretched, so that the blocking column 212 leaves the bottom of the support foot 207, and at this time, the lower clamping block 104 is just pressed. Then the lifting motor 201 rotates to drive the vertical screw rod 206 to rotate, thereby driving the support foot 207 to descend along the vertical frame 102, so that the support foot 207 contacts the ground to provide support for the device, and at the same time, the vertical screw rod 206 rotates to drive the side bevel gear 203 to rotate through the lifting bevel gear 202, thereby driving the docking bevel gear 205 to rotate through the side shaft 204. The rotation of the docking bevel gear 205 will simultaneously drive the docking gear 306 to rotate, thereby driving the screw shaft 307 to rotate, thereby driving the outer slide 303 to slide outward along the connecting plate 301 through the rope slide 302, the middle slide 304 and the lower slide 305, thereby driving the upper extrusion plate 309 and the lower extrusion plate 311 to contact and adhere to the outer wall of the refrigerator, and then detect the balance state of the refrigerator through the position between the sensor 318 and the induction plate 317. When the refrigerator is tilted, the upper extrusion plate 309 will rotate relative to the outer slide 303 or the lower extrusion plate 311 will rotate relative to the outer slide 303, so that the distance between the induction plate 317 and the sensor 318 will change, and the reading by the sensor 318 indicates that the refrigerator is in an unbalanced state.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope of the present invention, which should be covered by the protection scope of the present invention.
