[0014] Secondly, embodiments of this application provide a method for calibrating the position of an electrical appliance, applied to the position calibration device described above. The method includes: obtaining the distances S1, S2, S3, and S4 between four calibration rods and the inner walls of their respective cabinets, and the distance S0 between any calibration rod and the inner wall of the corresponding cabinet when the electrical appliance is centered in the cabinet, wherein S1 and S4 are the distances between the two calibration rods on the left and the inner walls of their respective cabinets, and S2 and S3 are the distances between the two calibration rods on the right and the inner walls of their respective cabinets; controlling the drive device to rotate, causing a pair of moving components to move in opposite directions along the axial direction of the screw, thereby pushing the four calibration rods to move along the axial direction of their respective slide rods, so that S1=S2=S3=S4=S0.

[0015] In a possible implementation, the driving device includes a driving motor and a transmission mechanism. The position correction method includes: if S1 > S4 ≠ S0, detect the magnitude relationship between S2 and S4; if S2 < S4, control the driving motor to operate at a first speed and a first power so that the right correction rod runs S2 to reach the right support point; based on the right support point, control the driving motor to operate at a second speed and a second power until S1 = S4 ≠ S0; if S1 > S2, control the driving motor to operate at a first speed and a first power so that the right correction rod runs S2 to reach the right support point; based on the right support point, control the driving motor to operate at a second speed and a second power until S1 = S4 = S0, the second speed is less than the first speed and the rotation direction is opposite, and the second power is less than the first power.

[0016] In a possible implementation, the position correction method further includes: if S1 = S4 and S1 < S2, control the driving motor to operate at a first speed and a first power so that the left correction rod runs S1 to reach the left support point; based on the left support point, control the driving motor to operate at a second speed and a second power until S1 = S2 = S0.

[0017] In a possible implementation, the position correction method further includes: if S1 < S4 ≠ S0, detect the magnitude relationship between S3 and S1; if S3 < S1, control the driving motor to operate at a first speed and a first power so that the right correction rod runs S3 to reach the right support point; based on the right support point, control the driving motor to operate at a second speed and a second power until S1 = S4 ≠ S0; if S1 > S2, control the driving motor to operate at a first speed and a first power so that the right correction rod runs S2 to reach the right support point; based on the right support point, control the driving motor to operate at a second speed and a second power until S1 = S4 = S0, the second speed is less than the first speed and the rotation direction is opposite, and the second power is less than the first power.

The pair of screws with opposite rotation directions are coaxially arranged between the pair of slide rods and rotatably connected to their respective slide rods. One end of the moving component is threadedly connected to its corresponding screw, and the other end of the moving component is connected to the correction rod. The driving device is connected to the fixed rods and is used to drive the pair of screws to rotate, thereby causing the pair of moving components to move in opposite directions along the axial direction of the screws, so as to push the four correction rods to move along the axial direction of their respective slide rods, so that the distance between the four correction rods and the inner wall of their respective cabinets is the same. Therefore, by connecting a pair of screws with opposite directions of rotation to a pair of moving components, the rotational motion of the screws can be converted into linear motion in opposite directions, and push the four correction rods to move along the axial direction of the corresponding slide rods respectively. This allows electrical equipment to be placed in the center quickly, avoiding the impact of heat dissipation problems on its normal operation. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] like Figure 1 and Figure 2 As shown, this application embodiment provides a position correction device for an electrical appliance. The electrical appliance E is embedded in a cabinet C, and the position correction device 100 is disposed at the bottom of the electrical appliance E. The electrical appliance can be various household appliances such as refrigerators and washing machines. The position correction device 100 includes: a frame 1, four correction rods 2, a pair of screws 3 with opposite rotation directions, a pair of moving components 4, and a drive device 5.

[0030] The frame 1 includes a pair of sliding rods 11 arranged opposite each other and spaced apart, and a pair of fixed rods 12 connected between the pair of sliding rods 11 and spaced apart; each correction rod 2 is movably connected to one end of a sliding rod 11. Each end of each sliding rod 11 is connected to a correction rod 2, and the four correction rods 2 correspond one-to-one with the four ends of the pair of sliding rods 11 and are movably connected.

[0031] A pair of screws 3 with opposite directions of rotation are coaxially arranged between a pair of slide rods 11 and are rotatably connected to their respective slide rods 11. One end of the moving component 4 is threadedly connected to the corresponding screw 3, and the other end of the moving component 4 is connected to the correction rod 2. One of the pair of screws 3 is a left-handed screw, and the other is a right-handed screw.

[0032] The drive device 5 is connected to the fixed rod 12. The drive device 5 is used to drive a pair of screws 3 to rotate, thereby driving a pair of moving components 4 to move in opposite directions along the axis of the screws 3, so as to push the four correction rods 2 to move along the axis of the corresponding slide rods 11 respectively, so that the distance between the four correction rods 2 and the inner wall of the corresponding cabinet is the same.

[0033] Since one end of the moving component 4 is threadedly connected to the corresponding screw 3, and the other end of the moving component 4 is connected to the correcting rod 2, and the correcting rod 2 is movably connected to one end of the slide rod 11, the moving component 4 can be restricted from rotating with the screw 3, thereby causing the moving component 4 to move linearly along the axis of the screw 3. Simultaneously, because the screws 3 rotate in opposite directions, the moving components 4 each move linearly in opposite directions along the axis of the screw 3, pushing the four correcting rods 2 to move separately along the axis of their corresponding slide rods 11. When the distance between the four correcting rods 2 and the inner wall of their respective cabinets C is equal, it indicates that the electrical appliance has been centered inside the cabinet.

[0034] The position correction device 100 for electrical equipment provided in this application includes: a frame 1, four correction rods 2, a pair of screws 3 with opposite rotation directions, a pair of moving components 4, and a drive device 5; the frame 1 includes a pair of sliding rods 11 that are opposite to each other and spaced apart, and a pair of fixed rods 12 that are connected between the pair of sliding rods 11 and spaced apart; each correction rod 2 is movably connected to one end of a sliding rod 11; the pair of screws 3 with opposite rotation directions are coaxially arranged between the pair of sliding rods 11 and are rotatably connected to their respective sliding rods 11; one end of the moving component 4 is threadedly connected to the corresponding screw 3, and the other end of the moving component 4 is connected to the correction rod 2; the drive device 5 is connected to the fixed rods 12, and the drive device 5 is used to drive the pair of screws 3 to rotate, thereby causing the pair of moving components 4 to move in opposite directions along the axial direction of the screws 3, so as to push the four correction rods 2 to move along the axial direction of their respective sliding rods 11, so that the distance between the four correction rods 2 and the inner wall of the corresponding cabinet is the same. Therefore, by connecting a pair of screws 3 with opposite directions of rotation to a pair of moving components 4, the rotational motion of the screws 3 can be converted into linear motion in opposite directions, and push the four correction rods 2 to move along the axial direction of the corresponding slide rods 11 and abut against the inner wall of the cabinet C. This allows the electrical appliances to be placed in the center quickly, avoiding the impact of heat dissipation problems on their normal operation.

[0035] In some embodiments, the moving component 4 includes a moving block 41 and a push rod 42 rotatably connected to the moving block 41. The moving block 41 is threadedly connected to a corresponding screw 3, and the end of the push rod 42 away from the moving block 41 is rotatably connected to the correction rod 2.

[0036] like Figure 2 and Figure 3As shown, since the screws 3 rotate in opposite directions, the two moving blocks 41 also rotate in opposite directions. The moving blocks 41 are rotatably connected to the push rod 42, while the end of the push rod 42 furthest from the moving blocks 41 is rotatably connected to the correction rod 2. This restricts the rotation of the moving blocks 41 around the central axis of the screws 3, thereby allowing the moving blocks 41 to drive the push rod 42 to move axially along the screws 3. Furthermore, since one end of the push rod 42 is rotatably connected to the moving blocks 41, and the end of the push rod 42 furthest from the moving blocks 41 is rotatably connected to the correction rod 2, the push rod 42 can smoothly drive the correction rod 2 to move axially along the slide rod 11 without jamming or other problems during its axial movement along the screws 3.

[0037] In some embodiments, the slide rod 11 is provided with a slide groove extending axially, and the correction rod 2 is provided with a through hole corresponding to the slide groove. The correction rod 2 and one end of the slide rod 11 are movably connected by a fastening assembly passing through the through hole and the slide groove.

[0038] The fastening assembly includes screws and nuts. The screws pass through the through holes and the slide grooves and are tightened with the nuts to fix the alignment rod 2 and the slide rod 11 in place. During the position calibration process, the screws and nuts can be loosened to adjust the position of the alignment rod 2 according to the rotation of the screw 3. After the electrical equipment is placed in the center inside the cabinet, the screws and nuts are tightened again to prevent the fastening assembly from falling off. This method is also inexpensive.

[0039] In some embodiments, either the slide rod 11 or the correction rod 2 is provided with a slide rail, and the other slide rod 11 or the correction rod 2 is provided with a slider that is slidably connected to the slide rail.

[0040] Optionally, the slide bar 11 is provided with a slide rail, and the correction rod 2 is provided with a slider that is slidably connected to the slide rail. This allows the correction rod 2 to move back and forth axially relative to the slide bar 11 without tightening or loosening screws, thereby improving correction efficiency and ease of operation.

[0041] In some embodiments, the correction rod 2 includes a first rod portion 21 and a second rod portion 22 arranged in a T-shape. The first rod portion 21 is movably connected to the slide rod 11, and the second rod portion 22 is used to contact the inner wall of the cabinet C.

[0042] Optionally, the correction rod 2 is made of plastic to prevent it from contacting and scratching the inner wall of the cabinet C.

[0043] In some embodiments, the drive device 5 includes a drive motor 51 and a transmission mechanism 52. The drive motor 51 is connected to the fixed rod 12, one end of the transmission mechanism 52 is connected to the output shaft of the drive motor 51, and the other end of the transmission mechanism 52 is connected to a pair of screws 3.

[0044] The transmission mechanism 52 can be a speed reducer, or it can be used only for transmission without speed reduction. The transmission mechanism 52 can be a pulley assembly, a sprocket assembly, or a gear reducer, etc.

[0045] In some embodiments, the transmission mechanism 52 includes a conveyor belt 521 and a drive pulley (not shown) and a driven pulley 523 connected to the conveyor belt 521. The drive pulley is connected to the output shaft of the drive motor 51, and the driven pulley 523 is connected to a pair of screws 3.

[0046] like Figure 2 and Figure 3 As shown, the driving pulley is connected to the output shaft of the drive motor 51, and the driven pulley 523 is connected to a pair of screws 3. When the driven pulley 523 rotates in one direction, it can drive the pair of screws 3 to rotate in the same direction, thereby causing the two moving components 4 to move in opposite directions, thus driving the four correction rods 2 to move to the left and right respectively.

[0047] In some embodiments, the transmission mechanism 52 includes a transmission chain and a drive sprocket and a driven sprocket connected to the transmission chain. The drive sprocket is connected to the output shaft of the drive motor 51, and the driven sprocket is connected to a pair of screws 3.

[0048] The working principle of the sprocket assembly is the same as that of the pulley assembly, so it will not be described again.

[0049] In some embodiments, the position correction device further includes multiple distance sensors disposed on the side of the correction rod 2 facing the inner wall of the cabinet C. The distance sensors can be infrared sensors or photoelectric sensors, etc., and are not limited thereto. The distance sensors can provide feedback on the distance between the correction rod 2 and the inner wall of the cabinet C, facilitating the adjustment of the position of the electrical equipment.

[0050] In some embodiments, the bottom of the electrical appliance E is provided with rollers W, and the maximum height of the position correction device is less than or equal to the height of the rollers W. Optionally, the height of the frame 1 is the maximum height of the position correction device, which is less than or equal to the height of the rollers W. When the correction rod 2 abuts against the inner wall of the cabinet C, the electrical appliance can be moved by the rollers W.

[0051] like Figure 4 As shown in the figure, this application embodiment also provides a position correction method for electrical equipment, which is applied to the position correction device for electrical equipment as described above. The position correction method includes the following steps S1-S2.

[0052] Step S1: Obtain the distances S1, S2, S3, and S4 between the four calibration rods 2 and the inner walls of their respective cabinets C, and the distance S0 between any one of the calibration rods 2 and the corresponding inner wall of the cabinet C when the electrical device E is centered in the cabinet C. Among them, S1 and S4 are the distances between the two calibration rods 2 on the left side and the corresponding inner walls of the cabinet C, and S2 and S3 are the distances between the two calibration rods 2 on the right side and the corresponding inner walls of the cabinet C.

[0053] Step S2: Control the driving device 5 to rotate, driving a pair of moving components 4 to move in opposite linear motions along the axial direction of the screw rod 3 respectively, so as to push the four calibration rods 2 to move along the axial direction of the corresponding slide rod 11 respectively, so that S1 = S2 = S3 = S4 = S0.

[0054] In this embodiment, as Figure 2 shown, the driving device 5 includes a driving motor 51 and a transmission mechanism 52. The position correction method includes: first setting the electrical device parallel to the inner wall of the cabinet, and then adjusting the distance between the electrical device and each inner wall.

[0055] Specifically, the position correction method includes the following steps:

[0056] Step S21: If S1 > S4 ≠ S0, detect the magnitude relationship between S2 and S4; at this time, the electrical device is not parallel to the inner wall of the cabinet, that is, the electrical device is tilted to the right, and it is necessary to judge whether the electrical device is tilted to the left or right when tilted to the right.

[0057] Step S22: If S2 < S4, control the driving motor 51 to operate at the first speed and the first power, so that the right calibration rod 2 runs S2 to reach the right support point; at this time, the electrical device is tilted to the right and placed on the right, and it needs to be moved to the left.

[0058] Step S23: Based on the right support point, control the driving motor 51 to operate at the second speed and the second power until S1 = S4 ≠ S0; at this time, the electrical device is set parallel to the inner wall of the cabinet, and it is necessary to move the electrical device as a whole parallel to the left or right again.

[0059] Step S24: If S1 > S2, control the driving motor 51 to operate at the first speed and the first power, so that the right calibration rod 2 runs S2 to reach the right support point; at this time, the electrical device is parallel to the inner wall of the cabinet and it is necessary to move the electrical device as a whole parallel to the left again.

[0060] Step S25: Based on the right support point, control the drive motor 51 to operate at a second speed and a second power until S1 = S4 = S0. The second speed is less than the first speed and the rotation direction is opposite, and the second power is less than the first power. That is, first quickly abut the calibration rod 2 against the inner wall of the cabinet C at the faster first speed with the minimum distance, so that the electrical equipment is parallel to the inner wall of the cabinet C, and then slowly adjust the left and right positions of the electrical equipment at the slower second speed to place it in the center.

[0061] Further, the position calibration method further includes:

[0062] Step S26: If S1 = S4 and S1 < S2, control the drive motor 51 to operate at the first speed and the first power so that the left calibration rod 2 runs S1 to reach the left support point; at this time, the electrical equipment is arranged parallel to the inner wall of the cabinet and the electrical equipment needs to be moved parallel to the right as a whole.

[0063] Step S27: Based on the left support point, control the drive motor 51 to operate at a second speed and a second power until S1 = S2 = S0. At this time, the electrical equipment is placed in the center of the cabinet.

[0064] In some embodiments, the position calibration method further includes:

[0065] Step S21': If S1 < S4 ≠ S0, then detect the magnitude relationship between S3 and S1; at this time, the electrical equipment is not parallel to the inner wall of the cabinet, that is, the electrical equipment tilts to the left, and it is necessary to judge whether the electrical equipment tilts to the left and leans to the left or tilts to the left and leans to the right.

[0066] Step S22': If S3 < S1, control the drive motor 51 to operate at the first speed and the first power so that the right calibration rod 2 runs S3 to reach the right support point; at this time, the electrical equipment tilts to the left and leans to the right, and it needs to be moved to the left.

[0067] Step S23': Based on the right support point, control the drive motor 51 to operate at a second speed and a second power until S1 = S4 ≠ S0; at this time, the electrical equipment is arranged parallel to the inner wall of the cabinet, and the electrical equipment needs to be moved parallel to the left or right as a whole.

[0068] Step S24': If S1 > S2, control the drive motor 51 to operate at the first speed and the first power so that the right calibration rod 2 runs S2 to reach the right support point; at this time, the electrical equipment is parallel to the inner wall of the cabinet and the electrical equipment needs to be moved parallel to the left as a whole.

[0069] Step S25': Based on the right support point, control the drive motor 51 to operate at a second speed and a second power until S1 = S4 = S0, where the second speed is less than the first speed and the rotation direction is opposite, and the second power is less than the first power. That is to say, first quickly abut the correction rod 2 against the inner wall of the cabinet C at the fastest first speed with the minimum distance to keep the electrical equipment parallel to the inner wall of the cabinet C, and then slowly adjust the left and right positions of the electrical equipment at the slower second speed to place it in the middle.

[0070] Further, the position correction method further includes:

[0071] Step S26': If S1 = S4 and S1 < S2, control the drive motor 51 to operate at the first speed and the first power so that the left correction rod 2 runs S1 to reach the left support point; at this time, the electrical equipment is arranged parallel to the inner wall of the cabinet and needs to move the whole electrical equipment parallel to the right again.

[0072] Step S27': Based on the left support point, control the drive motor 51 to operate at a second speed and a second power until S1 = S4 = S0. At this time, the electrical equipment is placed in the middle of the cabinet.

[0073] Further, if S1 = S4 = S0, it means that the electrical equipment is parallel to the inner wall of the cabinet and placed in the middle, and the drive motor 51 does not need to be started.

[0074] Thus, the position correction method of the electrical equipment provided by the embodiment of the present application detects the distances S1, S2, S3, and S4 between the four correction rods 2 and the inner walls of the respective corresponding cabinets C. The position of the electrical equipment in the cabinet can be judged by the size of the distances, including six position models: the electrical equipment is parallel to the cabinet and靠左, the electrical equipment is parallel to the cabinet and靠右, the electrical equipment is left-tilted and靠左, the electrical equipment is left-tilted and靠右, the electrical equipment is right-tilted and靠左, and the electrical equipment is right-tilted and靠右. Different correction methods are adopted for different position models, so as to achieve the fast, energy-saving, permanent, accurate, and automatic centering placement of the embedded electrical equipment, greatly improving the heat dissipation efficiency of the electrical equipment and making the placement of the embedded electrical equipment more beautiful.
