[0042] This disclosure provides a housing assembly including a housing body 1, a door 2, a movable bushing 6, a hinge plate 5, and an unlocking handle 4. The door 2 is disposed on the housing body 1, and a fixed bushing 201 is provided on the pivot side of the door 2. The movable bushing 6 is slidably disposed within the fixed bushing 201, and a first limiting groove 601 is provided on the inner side of the movable bushing 6. The hinge plate 5 includes a mounting plate 501 and a rotating shaft 502 inserted into the movable bushing 6, and a first limiting protrusion 503 is provided at the position corresponding to the first limiting groove 601 on the rotating shaft 502. The unlocking handle 4 is rotatably disposed on the door 2 and connected to the movable bushing 6 via a drive rod 3. When the door 2 is closed, the first limiting protrusion 503 engages with the first limiting groove 601, locking the door 2; the unlocking handle 4 rotates and drives the movable bushing 6 to slide downward through the drive rod 3, so that the first limiting protrusion 503 disengages from the first limiting groove 601, unlocking the door 2.
[0043] Specifically, when the housing assembly is in the locked state, the unlocking handle 4 lifts the movable bushing 6 via the drive rod 3, so that the first limiting groove 601 of the movable bushing 6 engages with the first limiting protrusion 503 of the rotating shaft 502. Rotating the unlocking handle 4 causes the drive rod 3 to move downward, so that the movable bushing 6 slides downward and disengages from the rotating shaft 502, thereby unlocking the housing assembly.
[0044] The length of the first limiting protrusion 503 is less than the sliding distance of the movable bushing 6. This ensures that when the movable bushing 6 slides upward to the locked position, the first limiting protrusion 503 engages with the first limiting groove 601 to lock the housing assembly; when the movable bushing 6 slides downward to the unlocked position, the first limiting protrusion 503 disengages from the first limiting groove 601 to unlock the housing assembly.
[0045] In some embodiments, the rotating shaft 502 is provided with multiple sets of first limiting protrusions 503, and the movable bushing 6 is provided with multiple sets of first limiting grooves 601.
[0046] Specifically, the rotating shaft 502 is provided with two sets of first limiting protrusions 503, and the two sets of first limiting protrusions 503 are symmetrically arranged with the axis of the rotating shaft 502 as the center line. The movable bushing 6 is provided with two sets of first limiting grooves 601, which correspond to the positions of the first limiting protrusions 503. This arrangement can increase the stability of the engagement between the movable bushing 6 and the rotating shaft 502 when the housing assembly is in the locked state.
[0047] In some embodiments, the fixed bushing 201 is provided with a second limiting groove 2011, and the movable bushing 6 is provided with a second limiting protrusion 602 at a position corresponding to the second limiting groove 2011. The second limiting protrusion 602 can be engaged with the second limiting groove 2011 so that the movable bushing 6 slides along a predetermined trajectory within the fixed bushing 201.
[0048] Specifically, the height of the movable bushing 6 is less than the height of the fixed bushing 201, so that the movable bushing 6 can slide up and down within the fixed bushing 201. For example, the height of the movable bushing 6 can be 4 / 5, 3 / 4, or 2 / 3 of the height of the fixed bushing 201.
[0049] In some embodiments, the movable bushing 6 is provided with multiple sets of second limiting protrusions 602, and the fixed bushing 201 is provided with multiple sets of second limiting grooves 2011.
[0050] Specifically, the movable bushing 6 is provided with two sets of second limiting protrusions 602, and the two sets of second limiting protrusions 602 are symmetrically arranged with the axis of the movable bushing 6 as the center line. The fixed bushing 201 is provided with two sets of second limiting grooves 2011, and the positions correspond to the second limiting protrusions 602. This arrangement ensures that the movable bushing 6 slides within the fixed bushing 201 along a preset trajectory, preventing the movable bushing 6 from disengaging from the fixed bushing 201.
[0051] In some embodiments, the drive lever 3 includes a first segment 301 and a second segment 302. The first segment 301 abuts against the lower end face of the movable bushing 6, and the second segment 302 abuts against the unlocking handle 4. The included angle between the first segment 301 and the second segment 302 is a first included angle θ.
[0052] Specifically, the first rod segment 301 is located at the upper end of the door body 2, and the second rod segment 302 is located at the side end of the door body 2, wherein the upper end and the side end are adjacent. By arranging the drive rod 3 along the edge of the door body 2, it is possible to connect the unlocking handle 4 and the movable bushing 6 without affecting the aesthetics of the door body 2 or the wiring layout. Preferably, the first included angle θ is 90°.
[0053] In some embodiments, the unlocking handle 4 includes a latch 401 and an abutment end 402 that is bent and connected to the latch 401. The unlocking handle 4 is rotatable about the connection between the latch 401 and the abutment end 402.
[0054] Specifically, a handle mounting groove is provided at the side end of the door body 2 for installing the unlocking handle 4 and for providing space for the unlocking handle 4 to rotate. The handle mounting groove extends through the door body 2. The abutting end 402 of the unlocking handle 4 abuts against the second rod segment 302 of the drive rod 3. When the handle 401 is subjected to force, the unlocking handle 4 can rotate around the connection between the handle 401 and the abutting end 402, thereby causing the abutting end 402 to drive the drive rod 3 to move, so as to unlock or lock the box assembly.
[0055] In some embodiments, the included angle between the handle 401 and the abutment end 402 is less than 90°.
[0056] Specifically, the angle between the handle 401 and the abutment end 402 is less than 90°, which can reduce the installation space of the handle 401 while ensuring that the unlocking handle 4 rotates and drives the drive rod 3. For example, the angle between the handle 401 and the abutment end 402 can be 70°, 60°, 50° or 40°.
[0057] In some embodiments, the housing assembly further includes an elastic element 8. The elastic element 8 is disposed at the handle 401 for resetting the unlocking handle 4.
[0058] Specifically, the first end of the elastic element 8 is connected to the handle 401, and the second end is connected to the door body 2. When the door body 2 is locked, the handle 401 is forced to rotate the unlocking handle 4 and squeeze the elastic element 8, causing the drive rod 3 to drive the movable sleeve 6 downward to unlock the door body 2. When the force on the handle 401 is released, the elastic element 8 squeezes the handle 401, causing the unlocking handle 4 to rotate, which in turn drives the movable sleeve 6 upward through the drive rod 3 to lock the door body 2.
[0059] In some embodiments, the door body 2 further includes a door handle 7. The door handle 7 is disposed on the outside of the unlocking handle 4. The first end of the elastic element 8 abuts against the door handle 7, and the other end abuts against the unlocking handle 4.
[0060] Specifically, the door handle 7 is located on the outside of the unlock handle 4 and is fixedly connected to the door 2. The door 2 can be opened or closed by means of the door handle 7. This arrangement also allows the user to apply force to both the unlock handle 4 and the door handle 7 simultaneously when opening the door 2, thereby unlocking and opening the door 2, which improves the user experience.
[0061] In some embodiments, the door handle 7 is further provided with a rotating protrusion 701. The unlocking handle 4 is rotatably disposed on the rotating protrusion 701.
[0062] Specifically, the rotating protrusion 701 is positioned at the location corresponding to the handle mounting groove of the door handle 7, and the connection between the handle 401 and the abutment end 402 is rotatably located on the rotating protrusion 701. When the handle 401 is subjected to force, the unlocking handle 4 can rotate around the rotating protrusion 701.
[0063] In some embodiments, the door handle 7 includes a grip portion and a connecting portion for connecting the grip portion and the door body 2. The connecting portion is disposed at both ends of the grip portion, and a preset distance L1 exists between the grip portion and the door body 2.
[0064] Specifically, the preset distance L1 between the handle and the door 2 is greater than or equal to 2cm. For example, the preset distance L1 can be 2cm, 2.5cm, or 3cm. This setting makes it more convenient for users to use the unlocking handle 4 located inside the door handle 7.
[0065] In some embodiments, a rotating protrusion 701 is disposed between the handle portion of the door handle 7 and the door body 2.
[0066] Specifically, by placing the rotating protrusion 701 between the grip of the door handle 7 and the door 2, the clearance space for the unlocking handle 4 can be increased, allowing the unlocking handle 4 to rotate at a larger angle, thereby improving the user experience and avoiding the situation where the door 2 cannot be unlocked due to the unlocking handle 4 not rotating in place.
[0067] In some embodiments, the hinge plate 5 is disposed on the left or right side of the opening of the housing body 1.
[0068] Specifically, the mounting plate 501 of the hinge plate 5 is fixedly disposed on the left side of the opening of the housing body 1, the movable bushing 6 is disposed on the left side of the door body 2, and the door handle 7 and the unlocking handle 4 are disposed on the right side of the door body 2, so that when the right side of the door body 2 is subjected to force, it can rotate around the hinge plate 5 on the left side to open the opening of the housing body 1. Similarly, the mounting plate 501 of the hinge plate 5 is fixedly disposed on the right side of the opening of the housing body 1, the movable bushing 6 is disposed on the right side of the door body 2, and the door handle 7 and the unlocking handle 4 are disposed on the left side of the door body 2, so that when the left side of the door body 2 is subjected to force, it can rotate around the hinge plate 5 on the right side to open the opening of the housing body 1.
[0069] The above "left side" and "right side" are based on Figure 1 The description of the positional relationship between the hinge plate 5, the box body 1, and the door 2 is provided to facilitate the understanding of this application by those skilled in the art and does not constitute a limitation on this application.
[0070] In some embodiments, the door 2 includes a main door 202 and a secondary door 203. The main door 202 is located at the opening of the housing body 1, and the secondary door 203 is located outside the main door 202. A fixed bushing 201 and a drive rod 3 are located on the secondary door 203. The hinge plate 5 includes a main door 202 hinge plate 5 and a secondary door 203 hinge plate 5. The main door 202 hinge plate 5 connects the main door 202 and the housing body 1, and the secondary door 203 hinge plate 5 connects the secondary door 203 and the main door 202. A pivot 502 is located on the secondary door 203 hinge plate 5.
[0071] Specifically, the elastic element 8 presses the unlocking handle 4, causing the unlocking handle 4 to rotate and drive the movable bushing 6 upward via the drive rod 3. This causes the first limiting groove 601 to engage with the first limiting protrusion 503, locking the secondary door 203 to the main door 202. At this time, the door handle 7 can simultaneously drive the main door 202 and the secondary door 203 to rotate synchronously. When the unlocking handle 4 is forced to rotate, it presses the elastic element 8, causing the drive rod 3 to drive the movable bushing 6 downward. This causes the first limiting groove 601 to disengage from the first limiting protrusion 503, unlocking the secondary door 203 to the main door 202. At this time, the door handle 7 can drive the secondary door 203 to rotate without driving the main door 202 to rotate.
[0072] This disclosure also provides a refrigeration device, including the aforementioned housing assembly.
[0073] Preferably, the aforementioned refrigeration equipment is a door-in-door refrigerator.
