[0031] Refer to Figures 1 to 8, an installation structure of a translation stroke control component, including a guide rail base 1, a translation stroke control component, and a drawer 8 that is slidably connected to the front and back of the guide rail base 1. The translation stroke control component is used to control the front and back translation of the drawer 8. An installation area 10 is provided on the guide rail base 1, and the translation stroke control component is installed on the installation area 10. A limiting block is provided on the installation area 10, and a shaft hole 13 is provided on the limiting block. A notch 131 is provided on the side wall of the shaft hole 13. A rotating shaft 412 adapted to the shaft hole 13 is fixedly provided on the translation stroke control component. The rotating shaft 412 is pressed into the shaft hole 13 through the notch 131, and the rotating shaft 412 can rotate in the shaft hole 13. A first locking hook 11 is provided at the front end of the installation area 10, and a second locking hook 411 is provided at the front end of the translation stroke control component. When the rotating shaft 412 rotates in the shaft hole 13, the second locking hook 411 is latched with the first locking hook 11 from top to bottom. During installation, first, the rotating shaft 412 is snapped into the shaft hole 13 through the notch 131. Then, by rotating the translation stroke control component, the front end of the translation stroke control component moves downward, and the second locking hook 411 is caught below the first locking hook 11, thereby completing the installation of the translation stroke control component. The installation is convenient, without the need for screw fastening, and high-efficiency production and manufacturing can be carried out.

[0032] In a preferred embodiment, the limiting block includes a left rear limiting block 14 and a right rear limiting block 15. The left rear limiting block 14 and the right rear limiting block 15 are respectively arranged on the left and right sides of the rear end of the installation area 10. The rotating shafts 412 are provided on both the left and right sides of the translation stroke control component, and the translation stroke control component is arranged between the left rear limiting block 14 and the right rear limiting block 15. The degrees of freedom on both the left and right sides of the translation stroke control component are reduced. The length of the notch 131 is less than the diameter of the rotating shaft 412, and the limiting block has a certain elasticity.

[0033] In a preferred embodiment, a first inclined surface 111 is provided at the upper end of the first locking hook 11, and a second inclined surface 4111 corresponding to the first inclined surface 111 is provided at the lower end of the second locking hook 411. After the translation stroke control component rotates a certain angle, the second inclined surface 4111 comes into contact with the first inclined surface 111. After the second inclined surface 4111 comes into contact with the first inclined surface 111, the first locking hook 11 and the second locking hook 411 are forced to open to the left and right sides respectively, so that the second locking hook 411 can fall below the first locking hook 11. By setting the inclined surface, it is convenient to assemble the translation stroke control component.

[0034] In a preferred embodiment, the first locking hook 11 is disposed on the left side of the front end of the installation area 10, and a right front limiting block 17 is disposed on the right side of the front end of the installation area 10. The translation stroke control assembly is clamped between the first locking hook 11 and the right front limiting block 17, further reducing the degrees of freedom on both the left and right sides of the translation stroke control assembly.

[0035] In a preferred embodiment, a controller (not shown) is further included. Both the guide rail base 1 and the drawer 8 are strip-shaped and arranged in the front-back direction. The drawer 8 is slidably connected to the guide rail base 1 in the front-back direction. A roller 2 is installed on the guide rail base 1. The roller 2 is electrically connected to the controller. The top of the roller 2 abuts against the bottom of the drawer 8. When the drawer 8 is translated, the roller 2 can be driven to roll. A magnet 3 is embedded in the roller 2. The magnet 3 is a circular magnet with radial magnetization and a single N / S pole. The magnet 3 rotates synchronously with the roller 2, and the magnetic field direction changes according to the rotation direction of the magnet 3. A translation stroke control assembly is installed on the guide rail base 1. The translation stroke control assembly includes a linear Hall sensor for detecting the magnetic field change of the magnet 3 and converting the magnetic field change into an electrical signal and transmitting it to the controller. By installing a linear Hall sensor and a roller 2 containing a magnet 3 on the guide rail base 1, the roller 2 abuts against the bottom of the drawer 8, and the linear Hall sensor is electrically connected to the controller. The linear Hall sensor detects the rolling direction of the magnet 3 in real time and outputs a corresponding electrical signal to the controller. When the drawer 8 is pushed or pulled, the roller 2 and the magnet 3 roll forward or backward. The linear Hall sensor detects the rolling direction of the magnet 3 and outputs a corresponding signal to the controller. When the controller receives the corresponding push / pull signal, it will control the refrigerator drawer 8 to close completely or open completely, realizing that when the drawer 8 is opened to any stroke and stopped, when the user subconsciously pushes the drawer 8, it will automatically close, and when pulling the drawer 8, it will automatically close, which conforms to the user's usage habit and improves the user's usage experience.

[0036] In a preferred embodiment, the translation travel control assembly further includes a housing 41, which is fixedly connected to the outside of the linear Hall sensor. The roller 2 is rotatably connected to the housing 41, and the position of the roller 2 is relatively fixed with respect to the linear Hall sensor assembly.

A vertical portion 16 is integrally provided on the guide rail base 1, and the first locking hook 11 is integrally provided at the upper end of the vertical portion 16. The vertical portion 16 has a certain height, and the second locking hook 411 can move up and down below the first locking hook 11 (rotate with the rotating shaft 412, and the up and down movement trajectory will have a certain arc). A compression spring 6 is further included. The two ends of the compression spring 6 respectively abut against the lower front part of the housing 41 and the guide rail base 1. Under the elastic force of the compression spring 6, the front end of the translation travel control assembly has a tendency to rotate upward. Thereby driving the roller 2 to tightly adhere to the bottom of the drawer 8 upward, increasing the static friction between the roller 2 and the drawer 8, and enabling better transmission between the roller 2 and the drawer 8.

[0037] In a preferred embodiment, the roller 2 includes a main body 21 and a fixing ring 22 fixed to the outer ring of the main body 21. The main body 21 is made of POM material, and the fixing ring 22 is made of rubber material. The POM material is hard and wear-resistant, ensuring a long service life. The fixing ring 22 is made of rubber material, which can effectively absorb collision noise, and at the same time increase the contact area with the drawer 8, ensuring relative rolling and avoiding sliding friction, further increasing the static friction between the roller 2 and the drawer 8, and enabling better transmission between the roller 2 and the drawer 8.

[0038] In a preferred embodiment, a baffle 5 is installed on the right side of the housing 41. There is a hollow between the baffle 5 and the right side surface of the housing 41 to form a through hole 7, and the roller 2 is installed in the through hole 7. By setting the baffle 5, the freedom degree of the roller 2 in the left and right directions is reduced.

[0039] In a preferred embodiment, the baffle 5 is snap-fitted onto the outer shell 41, which facilitates the installation of the baffle 5. Without the need for screw fastening, efficient production and manufacturing can be carried out. Specifically, a first mounting hole 414 is provided on the right side surface of the outer shell 41, and a second mounting hole 51 corresponding to the first mounting hole 414 is provided on the baffle 5.

In a possible implementation manner, bearings are installed between the extension portions and the mounting holes. Third locking hooks 415 and positioning holes 416 are provided on both the front and rear sides of the outer shell 41, and fourth locking hooks 52 and positioning posts 53 are provided on both the front and rear sides of the baffle 5. The third locking hook 415 and the fourth locking hook 52 are latched in the left-right direction, and the positioning post 53 is inserted into the positioning hole 416. The baffle 5 is installed on the outer shell 41 by means of snap-fastening, which is convenient for installation and improves the assembly efficiency.

[0040] In a preferred embodiment, a snap-in groove with a downward opening is provided at the front end of the bottom of the outer shell 41, and the upper end of the compression spring 6 is snap-fitted in the snap-in groove. By providing a snap-in groove with a downward opening at the front end of the bottom of the outer shell 41, the upper end of the compression spring 6 is snap-fitted in the snap-in groove, which facilitates the installation of the compression spring 6.
