Description

Technical Field

[0001] The present application relates to the technical field of refrigerators, and in particular to a fixing device and a refrigerator installation structure. Background Art

[0002] In order to prevent the refrigerator from moving relative to the environmental component due to unexpected force after it is installed in the designated position, it is necessary to set a fixing device between the refrigerator and the environmental component. The fixing device acts on the refrigerator wall and the environmental component, thereby forming a support between the refrigerator and the environmental component. For example, for a built-in refrigerator, the fixing device acts horizontally between the rear wall of the built-in refrigerator and the inner wall of the cabinet to prevent the built-in refrigerator from moving toward the inside of the cabinet after it is installed. The relevant structure requires customized fixing devices of different specifications for cabinets of different depths and refrigerators of different sizes, resulting in poor versatility of the fixing device. Alternatively, although the fixing device is configured to be adjustable in size, the user needs to manually adjust the mechanical connection structure of the fixing device, which is more cumbersome to use and requires the user to adjust the fixing device multiple times to adjust it to the required size, resulting in low efficiency.

[0024] Please refer to Figures 1 to 2 , this application provides a fixing device 100, which acts between the refrigerator wall surface and the environmental component. The fixing device 100 includes a bracket 10, an electric push rod 20 and a sensor. The bracket 10 is used to be fixed to the refrigerator wall surface. The electric push rod 20 is installed on the bracket 10. The electric push rod 20 includes a motor 21 and a telescopic rod 22. One end of the telescopic rod 22 is drivingly connected to the motor 21, and the other end is configured as an adjustment end 221 for cooperating with the environmental component. The sensor is installed on the adjustment end 221 and is used to collect the acting force between the adjustment end 221 and the environmental component for the motor 21 to perform corresponding actions. Among them, the environmental component includes but is not limited to the inner wall of a cabinet, a wall, etc. When actually using the fixing device 100, the corresponding actions of the motor 21 include actions such as driving the telescopic rod 22 to extend or retract, turning on, turning off, etc. mentioned below. When the fixing device 100 is in use, first fix the bracket 10 to the refrigerator wall surface, and then make the motor 21 drive the electric push rod 20 to extend or shorten according to the needs, so as to increase or decrease the length of the fixing device 100, so that the size of the fixing device 100 matches the actual distance between the refrigerator wall surface and the environmental component. And, by collecting the acting force between the adjustment end 221 and the environmental component through the sensor, it can assist in judging whether the adjustment end 221 has moved in place, which is beneficial to improving the accuracy of the size adjustment of the fixing device 100 and improving the adjustment efficiency. That is to say, the fixing device 100 provided by this application not only has high versatility, but also is relatively simple to operate and has high adjustment efficiency. Among them, the sensor is configured as a pressure sensor.

[0025] The fixing device 100 further includes a control switch, which is connected to the motor 21 by wire or wireless remote control and provides at least an opening signal to the motor 21. The user can also control the motor 21 to turn off through the control switch.

[0026] The fixing device 100 further includes a controller. The sensor and the motor 21 are both connected to the controller circuit. The controller is configured to receive the pressure signal from the sensor and send a closing signal to the motor 21 when the pressure signal reaches a threshold value. When the pressure signal reaches the threshold value, it indicates that the adjustment end 221 has moved into place on the surface of the environmental component. At this time, the motor 21 is turned off, the telescopic rod 22 remains in the extended state, and the fixing device 100 forms a stable support between the refrigerator wall and the environmental component. If the pressure signal does not reach the threshold value, the motor 21 continues to drive the telescopic rod 22 to extend.

[0027] The bracket 10 includes a base 11 and a support arm 12. The electric push rod 20 is installed on the base 11. The support arms 12 are configured in multiple numbers. One end of each support arm 12 is connected to the base 11, and the other end of each support arm 12 extends outward in an expanded shape and is used to connect to the refrigerator wall. In this way, the force between the base 11 and the refrigerator is dispersed to different positions on the refrigerator wall through the multiple support arms 12, so that the stress concentration can be avoided, and it is also beneficial for the fixing device 100 to support the refrigerator more stably. Among them, each support arm 12 is connected to the base 11 by snap connection or fixed connection by screws.

[0028] Further, a connecting seat 13 is respectively provided at one end of each support arm 12 away from the base 11, and the connecting seat 13 is used to connect to the refrigerator wall. The connecting seat 13 is used to increase the contact area between the support arm 12 and the refrigerator wall.

[0029] Optionally, the connecting seat 13 has a surface that fits the refrigerator wall, and the connecting seat 13 is fixed to the refrigerator wall by screws or directly bonded and fixed to the refrigerator wall.

[0030] The base 11 is provided with an installation groove 111, and at least a part of the motor 21 is located in the installation groove 111. In this way, at least a part of the motor 21 is embedded in the installation groove 111 of the base 11, making the structure of the fixing device 100 more compact. Further, fasteners such as screws can be added to fix the motor 21 to the base 11.

[0031] Specifically, the base 11 has a first side wall 112 and a second side wall 113 arranged oppositely. One ends of all the support arms 12 are gathered together and connected to the first side wall 112. The installation groove 111 is opened on the second side wall 113. The extending direction of the telescopic rod 22 is perpendicular to the second side wall 113. That is, the installation groove 111 and the support arm 12 are arranged away from each other.

[0032] Furthermore, the number of the support arms 12 is configured to be two, and the two support arms 12 are symmetrically arranged with respect to the extending direction of the telescopic rod 22. Of course, the number of the support arms 12 can also be set to three, four, five, etc., which is specifically set according to actual requirements.

[0033] The motor 21 includes a main shaft 211 and a commutation transmission assembly 212. The extending direction of the main shaft 211 is perpendicular to the extending direction of the telescopic rod 22, and the main shaft 211 and the telescopic rod 22 are linked through the commutation transmission assembly 212; the installation groove 111 includes a first installation area 111a and a second installation area 111b that communicate with each other. The first installation area 111a is used to accommodate the main shaft 211, and the second installation area 111b is used to accommodate the commutation transmission assembly 212. Among them, the linkage between the main shaft 211 and the telescopic rod 22 through the commutation transmission assembly 212 is a conventional technique in the art and will not be elaborated here.

[0034] Furthermore, along the direction of gravity, the first installation area 111a is relatively located below the second installation area 111b. The center of gravity of the motor 21 is usually at the position of the main shaft 211. By setting that along the direction of gravity, the first installation area 111a is relatively located below the second installation area 111b, the motor 21 is installed in the installation groove 111 at an angle with the center of gravity downward, so that the motor 21 can be firmly embedded in the installation groove 111 under its own gravity.

[0035] The present application also provides a refrigerator installation structure, which includes a cabinet and the fixing device 100 described in any one of the above embodiments. The cabinet serves as an environmental component, and the cabinet has a receiving area. The refrigerator is located in the receiving area. The refrigerator has a rear side facing the inner wall of the receiving area, and the fixing device 100 acts between the rear side of the refrigerator and the cabinet.

[0036] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brief description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0037] The above-described embodiments only express several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
