Description

Technical Field

[0001] This application relates to the field of storage equipment technology, such as a door lock assembly and a cabinet device. Background Technology

[0002] A door lock is a type of lock installed on a door. In daily life, door locks can be installed on the doors of furniture such as refrigerators, wardrobes, and cabinets to secure them. For example, if a refrigerator has been used for a long time, the seal may wear or deform, causing the door to not close properly. A loose door can lead to poor refrigeration, increased energy consumption, and frost buildup inside the refrigerator. Furthermore, if children are present in the home and the refrigerator door is not locked, they can easily open it and consume cold food.

[0003] Modern refrigerators typically have door locks installed on the door to prevent accidental opening and to keep the door locked inside the refrigerator.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] For refrigerators with locks on the secondary door, users need to unlock the door before opening it. This is inconvenient if the user has other items in their hands, thus reducing the user experience.

[0006] It should be noted that the information disclosed in the background section above is only for enhancing the understanding of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0008] This disclosure provides a door lock assembly and a housing device. Rotating the handle drives the push rod to move and press the bolt through the linkage assembly, thereby unlocking the door lock assembly. This solves the problem of inconvenience for users in unlocking the door and improves the user experience.

[0009] This disclosure provides a door lock assembly including a drive push rod, a latch, a fixed push rod, and a positioning device. The drive push rod is connected to a handle via a linkage assembly. The latch includes a first abutment surface that abuts against the drive push rod, and a second abutment surface corresponding to the first abutment surface. The fixed push rod includes a first insertion portion inserted into the drive push rod, and a first abutment portion that abuts against the second abutment surface of the latch. The positioning device includes a first elastic element for pushing the fixed push rod. The positioning device and the drive push rod are disposed opposite each other on opposite sides of the fixed push rod. When the door lock assembly is in the locked state, the latch abuts against the fixed push rod. The handle can drive the drive push rod to move via the linkage assembly and press the first abutment surface of the latch, causing the latch to move and disengage from the fixed push rod. Simultaneously, the positioning device pushes the fixed push rod, thus unlocking the door lock assembly.

[0010] In some embodiments, the handle includes a cam that abuts against the linkage assembly. When the handle is rotated, the linkage assembly can be moved via the cam.

[0011] In some embodiments, the linkage assembly includes a main linkage and a secondary linkage. The main linkage includes a first end that abuts against a cam of the handle, and a second end disposed opposite to the first end. One end of the secondary linkage is rotatably connected to the second end of the main linkage, and the other end is rotatably connected to a drive push rod. The first end of the main linkage is located below the second end.

[0012] In some embodiments, the angle between the axis of the secondary link and the axis of the drive push rod is a first angle θ. When the door lock assembly is in the locked state, the first angle θ is less than or equal to 45°.

[0013] In some embodiments, the main connecting rod is vertically arranged, and the drive push rod is horizontally arranged. When the door lock assembly is in the locked state, the handle is rotated, and the cam drives the main connecting rod to move vertically upwards, which in turn drives the drive push rod to move horizontally to press the latch.

[0014] In some embodiments, the door lock assembly further includes a second elastic element. One end of the second elastic element abuts against a drive push rod, and the other end abuts against a fixed push rod.

[0015] In some embodiments, two sets of locking tongues are symmetrically arranged vertically.

[0016] In some embodiments, the latch is further provided with a third elastic element, which can drive the latch to reset when the drive push rod disengages from the latch.

[0017] This disclosure also provides a cabinet device including a cabinet and a door disposed at the opening of the cabinet, and further including the aforementioned door lock assembly.

[0018] In some embodiments, the positioning device and the locking tongue are disposed within the housing. The drive push rod and the linkage assembly are disposed within the door body.

[0019] In some embodiments, the door body is provided with a first mounting groove for mounting the main connecting rod, and the first mounting groove is provided with a guide structure for guiding the movement of the main connecting rod.

[0020] In some embodiments, the door body is further provided with a second mounting groove, and the drive push rod is slidably disposed in the second mounting groove.

[0021] The door lock assembly and enclosure device provided in this disclosure can achieve the following technical effects:

[0022] This disclosure provides a door lock assembly including a drive push rod, a latch, a fixed push rod, and a positioning device. The drive push rod is connected to a handle via a linkage assembly. The latch includes a first abutment surface that abuts against the drive push rod and a second abutment surface corresponding to the first abutment surface. The fixed push rod includes a first insertion portion inserted into the drive push rod and a first abutment portion that abuts against the second abutment surface of the latch. The positioning device includes a first elastic element that abuts against the fixed push rod. When the user turns the handle, the handle can drive the drive push rod to move via the linkage assembly and press the latch, disengaging the latch from the fixed push rod, thus unlocking the door lock assembly. This makes it easier for the user to unlock the door lock assembly and improves the user experience.

[0042] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0043] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0044] This disclosure provides a door lock assembly and a housing device. Rotating the handle drives the push rod to move and press the bolt through the linkage assembly, thereby unlocking the door lock assembly. This solves the problem of inconvenience for users in unlocking the door and improves the user experience.

[0045] like Figures 1 to 7 As shown, this embodiment of the present disclosure provides a door lock assembly including a drive push rod 1, a latch 3, a fixed push rod 2, and a positioning device 5. The drive push rod 1 is connected to the handle 6 via a connecting rod assembly 4, and the drive push rod 1 is provided with a sliding groove 101, such as... Figure 5As shown. The locking tongue 3 includes a first abutting surface 3011 that can abut against the drive push rod 1, and a second abutting surface 3012 corresponding to the first abutting surface 3011. The fixed push rod 2 includes a first insertion part 201 inserted into the drive push rod 1, and a first abutting part 202 that can abut against the second abutting surface 3012 of the locking tongue 3, as shown. Figure 4 As shown. The positioning device 5 includes a first elastic element 501 for pushing the fixed push rod 2. The positioning device 5 and the driving push rod 1 are disposed opposite each other on both sides of the fixed push rod 2, as shown. Figure 2 As shown, when the door lock assembly is in the locked state, the bolt 3 abuts against the fixed push rod 2. The handle 6 can drive the drive push rod 1 to move and press the first abutment surface 3011 of the bolt 3 through the linkage assembly 4, so that the bolt 3 moves and disengages from the fixed push rod 2. At the same time, the positioning device 5 pushes the fixed push rod 2 to put the door lock assembly in the unlocked state. Figure 3 As shown.

[0046] It is understandable that the first abutting surface 3011 of the latch 3 is set as an inclined surface. In this way, when the drive push rod 1 or the fixed push rod 2 moves horizontally and presses the first abutting surface 3011 of the latch 3, the latch 3 can move vertically to make room, thereby unlocking or locking the door lock assembly.

[0047] Specifically, the first insertion part 201 of the fixed push rod 2 is inserted into the sliding groove 101 of the drive push rod 1, and the first insertion part 201 can slide back and forth within the sliding groove 101. Simultaneously, a limiting structure is provided within the sliding groove 101, and a limiting protrusion is provided at the position corresponding to the limiting structure on the first insertion part 201. When the first insertion part 201 slides outward to its maximum position, the limiting structure can stop the limiting protrusion to prevent the first insertion part 201 from disengaging from the sliding groove 101. Figure 2 As shown, when the door lock assembly is in the locked state, the drive push rod 1 disengages from the latch 3, and the fixed push rod 2 is in the locked position and abuts against the second contact surface 3012 of the latch 3. Turning the handle 6 allows the linkage assembly 4 to drive the drive push rod 1 horizontally towards the fixed push rod 2, pressing the first contact surface 3011 of the latch 3, causing the latch 3 to move vertically and disengage from the fixed push rod 2. At this time, the first elastic element 501 of the positioning device 5 pushes the fixed push rod 2, causing it to move horizontally towards the drive push rod 1 and slide to the unlocked position, thus unlocking the door lock assembly. Figure 3 As shown.

[0048] When the door lock assembly is in the unlocked state, pushing the handle 6 causes the drive push rod 1 and the fixed push rod 2 to move horizontally towards the bolt 3 via the linkage assembly 4, pressing the first abutment surface 3011 of the bolt 3, so that the bolt 3 moves vertically to make room. When the fixed push rod 2 moves to the locked position, the bolt 3 falls, and the fixed push rod 2 abuts against the second abutment surface 3012 of the bolt 3, so that the door lock assembly is in the locked state.

[0049] like Figure 1 As shown, in some embodiments, the handle 6 includes a cam that abuts against the linkage assembly 4. When the handle 6 is rotated, the linkage assembly 4 can be moved via the cam.

[0050] Specifically, the handle 6 includes a cam and a latch directly connected to the cam. The latch includes a first end connected to the cam, and the first end of the latch is provided with a pivot. The user can rotate the handle 6 around the pivot via the latch, thereby driving the linkage assembly 4 to move via the cam.

[0051] like Figure 2 As shown, in some embodiments, the linkage assembly 4 includes a main linkage 401 and a secondary linkage 402. The main linkage 401 includes a first end that abuts against the cam of the handle 6, and a second end disposed opposite to the first end. One end of the secondary linkage 402 is rotatably connected to the second end of the main linkage 401, and the other end is rotatably connected to the drive push rod 1. The first end of the main linkage 401 is disposed below the second end.

[0052] Specifically, the main connecting rod 401 and the drive push rod 1 are arranged perpendicularly to each other, and the auxiliary connecting rod 402 is used to connect the main connecting rod 401 and the drive push rod 1. When the door lock assembly is in the locked state, the main connecting rod 401 and the auxiliary connecting rod 402 are in the locked position. The handle 6 is rotated and the cam lifts the main connecting rod 401, which in turn drives the drive push rod 1 to move through the auxiliary connecting rod 402.

[0053] It is understandable that since the secondary connecting rod 402 is rotatably connected to the main connecting rod 401 and the drive push rod 1, when the main connecting rod 401 drives the drive push rod 1 to move through the secondary connecting rod 402, the drive push rod 1 can be guaranteed to move along a predetermined trajectory. For example, the drive push rod 1 can be made to move in a direction perpendicular to the direction of movement of the main connecting rod 401.

[0054] like Figure 2 As shown, in some embodiments, the angle between the secondary connecting rod 402 and the axis of the drive push rod 1 is a first angle θ. When the door lock assembly is in the locked state, the first angle θ is less than or equal to 45°.

[0055] Specifically, the first included angle θ is less than or equal to 45°. For example, it can be 40°, 35°, or 30°. This setting is more conducive to the main connecting rod 401 driving the drive push rod 1 to move in a direction perpendicular to the direction of movement of the main connecting rod 401.

[0056] Furthermore, when the door lock assembly is in the locked state, the first included angle θ is at its maximum, such as... Figure 2 As shown. The handle 6 rotates and, through the cam, lifts the main connecting rod 401, which in turn drives the push rod 1 via the secondary connecting rod 402. At this time, the door lock assembly is in the unlocked state, and the first included angle θ is at its minimum, as shown. Figure 3 As shown.

[0057] like Figure 2 As shown, in some embodiments, the main connecting rod 401 is vertically arranged, and the drive push rod 1 is horizontally arranged. When the door lock assembly is in the locked state, the handle 6 rotates, and the cam drives the main connecting rod 401 to move vertically upward, which in turn drives the drive push rod 1 to move horizontally through the auxiliary connecting rod 402 to press the latch 3.

[0058] Specifically, when the door lock is in the locked state, the drive push rod 1 is in the unlocked position, and the main connecting rod 401 abuts against the cam of the handle 6 and is at its lowest point. When the handle 6 is rotated, the cam pushes the main connecting rod 401 up, and through the secondary connecting rod 402, drives the drive push rod 1 to move horizontally towards the fixed push rod 2. The drive push rod 1 presses against the first abutment surface 3011 of the latch 3, causing the latch 3 to move vertically to make room.

[0059] like Figure 1 As shown, in some embodiments, the door lock assembly further includes a second elastic element 7. One end of the second elastic element 7 abuts against the drive push rod 1, and the other end abuts against the fixed push rod 2.

[0060] Specifically, when the door lock assembly is in the unlocked state, pushing the handle 6 causes the drive push rod 1 and the fixed push rod 2 to move horizontally towards the latch 3 via the linkage assembly 4, pressing the first abutment surface 3011 of the latch 3, so that the latch 3 moves vertically to make room. When the fixed push rod 2 moves to the locked position, the second elastic element 7 pushes the fixed push rod 2, so that the first insertion part 201 slides outward to the maximum position in the sliding groove 101. At the same time, the latch 3 resets, and the fixed push rod 2 abuts against the second abutment surface 3012 of the latch 3, so that the door lock assembly is in the locked state.

[0061] In some embodiments, the locking tongue 3 is provided in two sets symmetrically arranged vertically.

[0062] Understandably, symmetrically arranging two sets of latches 3 is beneficial to the stability of the door lock assembly when it is locked. At the same time, this arrangement can distribute the force on each individual latch 3, which helps to improve the durability of the door lock assembly.

[0063] like Figure 7As shown, in some embodiments, the latch 3 is also provided with a third elastic element 303. When the drive push rod 1 disengages from the latch 3, the third elastic element 303 can drive the latch 3 to reset.

[0064] Specifically, when the fixed push rod 2 moves to the locked position, the second elastic element 7 pushes the fixed push rod 2 so that the first insertion part 201 slides outward to the maximum position in the sliding groove 101. At the same time, the third elastic element 303 pushes the latch 3 to reset, and the fixed push rod 2 abuts against the second abutment surface 3012 of the latch 3 so that the door lock assembly is in the locked state.

[0065] like Figure 7 As shown, in some embodiments, the latch 3 includes a second insertion portion 302 and a second abutment portion 301 corresponding to the second insertion portion 302. The second abutment portion 301 includes a first abutment surface 3011 and a second abutment surface 3012.

[0066] Specifically, the second insertion portion 302 of the locking tongue 3 is inserted into the sliding sleeve 304, and the locking tongue 3 can slide within the sliding sleeve 304. A stop member 305 is provided at the end of the second insertion portion 302 opposite to the second abutment portion 301. The stop member 305 abuts against the sliding sleeve 304 to prevent the locking tongue 3 from disengaging from the sliding sleeve 304. Simultaneously, the first end of the third elastic element 303 abuts against the second abutment portion 301, and the second end abuts against the sliding sleeve 304.

[0067] like Figure 6 As shown, in some embodiments, the positioning device 5 includes a positioning end 502 and a fixed end 503 opposite to the positioning end 502. The first end of the first elastic element 501 is connected to the fixed end 503, and the second end is connected to the positioning end 502.

[0068] Specifically, the positioning end 502 of the positioning device 5 can abut against the first abutment portion 202 of the fixed push rod 2. When the drive push rod 1 moves and presses the bolt 3 to move, the fixed push rod 2 disengages from the second abutment surface 3012 of the bolt 3. At this time, the first elastic element 501 presses the positioning end 502 of the positioning device 5, so that the positioning end 502 pushes the fixed push rod 2 to move, thereby putting the door lock assembly in the unlocked state.

[0069] like Figure 8 and Figure 9 As shown, this embodiment of the disclosure also provides a box device including a box 8 and a door 9 disposed at the opening of the box 8, and also includes the aforementioned door lock assembly.

[0070] Specifically, the enclosure can be a refrigerator, a cabinet, etc.

[0071] like Figure 8As shown, in some embodiments, the positioning device 5 and the locking tongue 3 are disposed inside the housing 8. The drive push rod 1 and the connecting rod assembly 4 are disposed inside the door body 9.

[0072] Specifically, the housing 8 is provided with a fixing groove that can accommodate the locking tongue 3, and the locking tongue 3 is slidably disposed in the fixing groove. Among them, a bushing fixing structure is provided in the fixing groove, and the sliding bushing 304 is fixedly disposed in the bushing fixing structure.

[0073] like Figure 9 As shown, in some embodiments, the door body 9 is provided with a first mounting groove 901 for mounting the main connecting rod 401, and the first mounting groove 901 is provided with a guide structure 9011 for guiding the movement of the main connecting rod 401.

[0074] Specifically, the guide structure 9011 is a protrusion, and the guide structure 9011 fits against the main connecting rod 401 so that the main connecting rod 401 moves along a predetermined trajectory. When the handle 6 drives the main connecting rod 401 to move vertically in the first mounting groove 901, the guide structure 9011 can prevent the main connecting rod 401 from moving horizontally.

[0075] In some embodiments, the door body 9 is further provided with a second mounting groove 902, and the drive push rod 1 is slidably disposed in the second mounting groove 902.

[0076] Specifically, the second mounting groove 902 is perpendicular to the first mounting groove 901 so that the movement direction of the drive push rod 1 is perpendicular to the movement direction of the main connecting rod 401.

[0077] The foregoing description and accompanying drawings fully illustrate embodiments of the present disclosure to enable those skilled in the art to practice them. Other embodiments may include structural and other changes. The embodiments represent only possible variations. Individual components and functions are optional unless explicitly required, and the order of operation may vary. Parts and features of some embodiments may be included or substituted for parts and features of other embodiments.
