Description

Technical Field

[0001] This utility model relates to the technical field of refrigerator door structure, and in particular to a magnet mounting structure for a refrigerator door. Background Technology

[0002] Currently, refrigerator doors (such as French door, multi-door, and multi-door refrigerators) typically use magnetic switches to control their opening and closing. To prevent cold air leakage or magnet detachment from the magnet mounting location, traditional solutions usually employ the following two methods:

[0003] Sealing: After the magnet is installed, seal the joint between the magnet and the door cover with sealant to prevent cold air leakage and enhance the fixing effect of the magnet.

[0004] Double-sided tape + aluminum foil application: Apply double-sided tape to the contact surface between the magnet and the door cover for fixation, and apply aluminum foil to the corresponding position on the inside of the door cover to enhance sealing and fixing strength.

[0005] However, the aforementioned existing technology has the following problems:

[0006] Low production efficiency: Applying glue or double-sided tape requires additional manual operation, which affects assembly efficiency, and the glue has a long curing time, which is not conducive to rapid production.

[0007] Insufficient reliability: The glue or double-sided tape may age and fall off after long-term use, causing the magnet to loosen or even fall off, affecting the sealing of the refrigerator door.

[0008] Complex process: It requires an additional aluminum foil pasting process, which not only increases material costs, but may also lead to missed or poorly pasted foil due to improper operation by workers, affecting the quality of the final product.

[0009] Maintenance difficulties: If the magnet falls off during door transportation, the door cover needs to be disassembled and residual glue cleaned, resulting in high repair costs.

[0010] Therefore, there is an urgent need for a refrigerator door magnet mounting structure that is simple in structure, easy to install, and reliable in fixing, in order to overcome the shortcomings of existing technologies. Utility Model Content

[0040] Example 1

[0041] Reference Figures 1-3 The first embodiment of this utility model provides a refrigerator door magnet mounting structure, including a door cover connecting assembly 100 and a magnet fixing assembly 200, as detailed below:

[0042] Door cover connection assembly 100;

[0043] The door cover connecting assembly 100 includes a lower door cover 101 of the refrigerator door body. The lower door cover 101 is an injection-molded part, and a rectangular mounting groove 1011 is formed on its surface. The depth of the mounting groove 1011 is slightly greater than the thickness of the magnetic fixing assembly 200 to ensure that the assembly is flush with the surface of the door cover after installation. The bottom of the mounting groove 1011 has two symmetrically distributed insertion holes 1012 (approximately 3mm in diameter) for engaging with the pins of the magnetic fixing assembly 200 for positioning.

[0044] Magnet fixing assembly 200;

[0045] The magnet fixing assembly 200 includes a mounting box 201 and screws 202. The mounting box 201 is an ABS plastic injection molded part, with a semi-enclosed groove 2011 inside. The shape of the groove matches the magnet 300 (a cuboid neodymium iron boron magnet). An elastic hook 2012 is provided on the open side of the semi-enclosed groove 2011. The root of the hook is integrally formed with the mounting box 201, and the free end bends inwards into the groove to form an arc, which abuts against the outermost sidewall of the magnet 300 (see...). Figure 2 The bottom of the mounting box 201 has two cylindrical pins 2013 (diameter 2.8mm, height 5mm), which are interference-fitted with the insertion holes 1012 of the mounting slot 1011 to achieve pre-positioning.

[0046] The assembly process is as follows:

[0047] Insert the magnet 300 along the opening side of the semi-enclosed groove 2011. The elastic hook 2012 is squeezed and deformed outward. After the magnet is fully inserted, the hook springs back and locks the magnet.

[0048] Align the cylindrical pin 2013 of the mounting box 201 with the insertion hole 1012 of the mounting slot 1011 and press it down to complete the initial fixation;

[0049] Finally, screws 202 are passed through the screw holes of the mounting box 201 and locked to the mounting ribs 1013 of the lower door cover 101.

[0050] This embodiment avoids the glue application process through such a split design. The elastic hook 2012 and screw 202 provide double fixation to prevent the magnet from falling off, and the pin structure improves assembly accuracy.

[0051] Example 2

[0052] Reference Figures 4-5 This is the second embodiment of the present invention, which differs from the first embodiment in that it is further optimized based on embodiment 1:

[0053] 1. Improvements to the installation box 201:

[0054] The mounting box 201 has a flexible cavity 2014 at its bottom, located below the base of the flexible hook 2012, providing space for deformation. The free end of the flexible hook 2012 is designed with a curved shape to ensure tight contact with the sidewall of the magnet 300.

[0055] Two cylindrical pins 2013 are symmetrically distributed on both sides of the bottom of the mounting box 201, and the ends of the pins are designed with chamfers to facilitate insertion into the sockets 1012.

[0056] 2. Anti-fall-off mechanism:

[0057] When the magnet 300 is installed, the elastic hook 2012 unfolds outward, and the stress at its root is released through the elastic movable cavity 2014. After assembly, the rebound force of the hook and the side wall of the magnet 300 form a continuous clamping force, which, together with the mechanical fixation of the screw 202, prevents loosening.

[0058] This embodiment uses the design of the elastic movable cavity 2014 to protect the hook from fatigue fracture, and the double pin structure enhances the anti-torsion ability, making it suitable for transportation vibration scenarios.

[0059] Example 3

[0060] Reference Figure 3 and 4 This is the third embodiment of the present invention, which differs from the first embodiment in that: this embodiment adds an anti-slip and reinforcing structure based on embodiment 2.

[0061] 1. Anti-slip ribs 2015;

[0062] The upper inner wall and the left and right inner walls of the semi-enclosed groove 2011 are provided with anti-slip ribs 2015, with two parallel anti-slip ribs 2015 arranged on each side wall. The anti-slip ribs 2015 form multi-point contact with the side wall of the magnet 300, increasing the friction.

[0063] 2. Install rib 1013;

[0064] The bottom of the mounting slot 1011 of the lower door cover 101 is provided with a cross-shaped mounting rib 1013, and the mounting point of the screw 202 is located at the center of the cross intersection, which improves the local tensile strength.

[0065] In actual use, after the magnet 300 is installed, its top, bottom, left and right sides are limited by the anti-slip ribs 2015, and the outer side is locked by the elastic hooks 2012; when the screw 202 is screwed in, the cross ribs 1013 disperse the stress and prevent the plastic of the door cover from cracking.

[0066] This embodiment uses anti-slip ribs 2015 to prevent the magnet from moving slightly, and cross ribs 1013 to optimize the force distribution, making it suitable for installing large-size magnets.

[0067] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
