[0046] The following is for reference. Figures 1-6 This application describes a door lock 100 and a vehicle refrigerator 1000 according to embodiments thereof.

[0047] like Figure 1 and Figure 2 As shown, according to the first aspect embodiment of the present application, the door lock 100 includes: a housing 10, a bolt 20, an unlocking member 30, and a reset assembly 40.

[0048] The shell 10 is arranged in a cabinet 200 of a refrigerator, and has a receiving cavity 100a, and a door body 300 of the refrigerator has a lock slot 300a; the lock tongue 20 is movably arranged in the receiving cavity 100a, and is adapted to cooperate with the lock slot 300a; the unlocking piece 30 has a first arm 31 and a second arm 32, the first arm 31 and the second arm 32 have an included angle, a first end 31a of the first arm 31 is pivotally connected with the shell 10, the second arm 32 is adapted to rotate around the first end 31a of the first arm 31 in a first direction, and to push the lock tongue 20 to realize unlocking; the reset assembly 40 comprises a driving part 41 and a connecting rod 42, one end of the connecting rod 42 is connected with the driving part 41, the other end of the connecting rod 42 is connected to a connecting region of the first arm 31 and the second arm 32, the driving part 41 is adapted to drive the connecting rod 42, and to drive the second arm 32 to rotate around the first end 31a of the first arm 31 in a second direction, and to push the lock tongue 20 to realize locking, one of the first direction and the second direction is a clockwise direction, and the other is a counterclockwise direction.

[0049] Specifically, the shell 10 can be fixed on the cabinet 200 of the refrigerator to realize the installation and layout of the whole door lock 100. The shell 10 is formed with a receiving cavity 100a, which can accommodate part of other components (such as the lock tongue 20) of the door lock 100. The shell 10 can provide a mounting position for part of other components of the door lock 100 and play a supporting, fixing and protecting role on part of other components of the door lock 100. The lock tongue 20 is movably arranged in the receiving cavity 100a, and the door body 300 of the refrigerator is provided with a lock slot 300a for cooperating with the lock tongue 20. When the lock tongue 20 extends into the lock slot 300a, the door body 300 of the refrigerator can be locked with the cabinet 200 to improve the connection stability and reliability between the door body 300 and the cabinet 200, thereby improving the overall stability of the refrigerator. When the lock tongue 20 is separated from the lock slot 300a, the door body 300 and the cabinet 200 can be unlocked to allow the user to open the door body 300 for normal access to the goods. The unlocking piece 30 has a first arm 31 and a second arm 32, and a certain included angle is formed between the two arms, so that the unlocking piece 30 can rotate more flexibly when subjected to external force (such as manual operation of the handle, knob, etc.). The first end 31a of the first arm 31 is pivotally connected with the shell 10, so that the unlocking piece 30 can rotate relative to the shell 10 about the pivot point. The second arm 32 can rotate about the first end 31a of the first arm 31 in the first direction to physically contact and push the lock tongue 20, so that the lock tongue 20 exits from the lock slot 300a, thereby realizing the unlocking action. The reset assembly 40 can be used to realize the automatic locking function of the door lock 100. The reset assembly 40 includes a driving part 41 and a connecting rod 42. The other end of the connecting rod 42 is connected to the connection area of the first arm 31 and the second arm 32. The driving part 41 is used to drive the connecting rod 42 to push the connecting rod 42 to move, thereby driving the second arm 32 of the unlocking piece 30 to rotate about the first end 31a of the first arm 31 in the second direction to push the lock tongue 20 back to the locking position.

[0050] It should be noted that the first direction (i.e. the unlocking direction) and the second direction (i.e. the locking direction) are opposite. If the first direction is clockwise, the second direction is counterclockwise. If the first direction is counterclockwise, the second direction is clockwise.

[0051] According to the door lock 100 of the present application, the pure mechanical unlocking and locking of the door lock 100 can be realized through the cooperation of the latch 20, the unlocking member 30, the reset assembly 40 and the like, so that the door lock 100 does not need to rely on the power system or electronic components, and the unlocking failure caused by power failure or electronic control unit failure can be avoided, and the unlocking and locking reliability of the door lock 100 on the refrigerator can be effectively improved, and the user experience is improved. In addition, the electric unlocking system in the related art often has the problems of complex structure, high cost and high maintenance difficulty, while the door lock 100 of the present application has relatively few components, and the structure is compact and occupies small space, so that the material cost can be saved, the space utilization rate is optimized, and the installation and maintenance convenience of the door lock 100 is improved.

[0052] In some embodiments, by controlling the length of the latch 20 extending into the lock slot 300a, the unlocking speed can be adjusted to further improve the user experience.

[0053] In addition, in some specific embodiments of the present application, as shown in Figure 3 and Figure 4 , the first end 31a of the first arm 31 has a first shaft hole penetrating in the width direction, the shell 10 has a second shaft hole, the first shaft hole and the second shaft hole are sleeved on the same first shaft 62 to realize the pivotable connection between the first end 31a of the first arm 31 and the shell 10; the connection area of the first arm 31 and the second arm 32 has a third shaft hole penetrating in the width direction, the other end of the connecting rod 42 has a fourth shaft hole, the third shaft hole and the fourth shaft hole are sleeved on the same second shaft 63 to realize the pivotable connection between the other end of the connecting rod 42 and the unlocking member 30. The cooperation of the first shaft 62 and the first shaft hole and the second shaft hole, and the cooperation of the second shaft 63 and the third shaft hole and the fourth shaft hole, can improve the connection stability between the unlocking member 30 and the shell 10, and improve the connection and transmission stability between the connecting rod 42 and the unlocking member 30, thereby improving the locking and unlocking reliability and stability of the door lock 100.

[0054] As shown in Figure 4 , according to some embodiments of the present application, the moving direction of the latch 20 is configured as the third direction, and the driving part 41 includes a reset spring 411 movably arranged in the shell 10 along the third direction and connected with one end of the connecting rod 42, and the reset spring 411 is adapted to drive the connecting rod 42 and push the latch 20 to realize the locking.

[0055] Specifically, the return spring 411 is movably disposed in the housing 10 and connected to one end of the connecting rod 42. This can be understood as the return spring 411 being disposed between the housing 10 and the connecting rod 42. When the unlocking member 30 is subjected to external force, during the process of the second arm 32 rotating around the first end 31a of the first arm 31 in a first direction to unlock the latch 20, the unlocking member 30 can drive the connecting rod 42 to move, causing one end of the connecting rod 42 to move upwards in a third direction and compress the return spring 411. When the unlocking member 30 is free of external force, the compressed return spring 411, under its own elastic restoring force, can apply elastic force in a third direction, pushing the connecting rod 42 to move. This causes the other end of the connecting rod 42 to drive the second arm 32 of the unlocking member 30 to rotate around the first end 31a of the first arm 31 in a second direction, ultimately causing the latch 20 to extend into the lock groove 300a of the refrigerator door 300 in a third direction, thereby completing the locking action.

[0056] In this embodiment, a return spring 411 is provided. Utilizing the elastic properties of the return spring 411, precise control of the bolt 20's movement can be achieved, improving the stability and reliability of the locking and unlocking process. Furthermore, the door lock 100 automatically locks via the return spring 411, effectively improving locking efficiency, convenience, and automation, further enhancing the user experience. In addition, the return spring 411 has advantages in durability and low cost; therefore, using the return spring 411 also helps extend the service life of the door lock 100 and save costs.

[0057] In addition, in some embodiments, the specifications of the return spring 411 (such as the elastic coefficient or preload) can be set according to different refrigerators to flexibly adjust the moving speed and locking force of the latch 20 to meet the needs of different application scenarios. In this way, the adaptability and versatility of the door lock 100 to different refrigerators can be improved.

[0058] like Figure 3 and Figure 5 As shown, according to some embodiments of this application, one end of the connecting rod 42 is provided with a protrusion 421 protruding in the width direction of the connecting rod 42, and the driving part 41 further includes: a slider 412, the slider 412 is sleeved on at least a portion of the outer periphery of the protrusion 421, and the slider 412 is connected to the return spring 411 on the third direction side.

[0059] Specifically, one end of the connecting rod 42 is provided with a protruding portion 421 protruding in the width direction thereof, which is used to be sleeved with the sliding block 412 to realize the connection between the sliding block 412 and the connecting rod 42, so as to ensure that the sliding block 412 can be stably matched with the connecting rod 42. Wherein, the sliding block 412 is connected with the reset spring 411 on one side in the third direction, in the unlocking process, the connecting rod 42 can push the sliding block 412 to move in the third direction and compress the spring, in the locking process, the restoring force of the reset spring 411 pushes the sliding block 412 to move in the third direction, so as to drive the connecting rod 42 to move, and then drive the unlocking piece 30 to rotate and push the lock tongue 20 to realize the locking. By arranging the sliding block 412 between the connecting rod 42 and the reset spring 411, on the one hand, the connection area can be increased, the transmission stability between the connecting rod 42 and the reset spring 411 can be enhanced, and the smoothness of the locking and unlocking of the door lock 100 can be improved; on the other hand, the sliding block 412 can also play a good guiding role, so as to improve the movement accuracy of the reset spring 411 and one end of the connecting rod 42 in the third direction, which is conducive to improving the efficiency of the whole transmission system of the door lock 100.

[0060] As shown in Figure 3 According to some embodiments of the present application, the shell 10 comprises: a first shell plate body 11 and a second shell plate body 12.

[0061] Wherein, the first shell plate body 11 and the second shell plate body 12 are oppositely arranged and at least partially spaced apart, and define a receiving cavity 100a, the inner wall of the side of the first shell plate body 11 opposite to the second shell plate body 12 has a groove 11a protruding away from the second shell plate body 12, and the groove 11a extends in the third direction, the reset spring 411 and the sliding block 412 are accommodated in the groove 11a, and at least part of the inner wall of the groove 11a abuts against the two sides of the sliding block 412 in the width direction.

[0062] Specifically, the shell 10 is composed of a first shell plate body 11 and a second shell plate body 12, at least part of the first shell plate body 11 and the second shell plate body 12 are spaced apart and jointly define a receiving cavity 100a, the split of the first shell plate body 11 and the second shell plate body 12 facilitates assembly and disassembly maintenance, and also facilitates providing sufficient space for internal components of the door lock 100. The inner wall of the first shell plate body 11 opposite to the second shell plate body 12 has a groove 11a, the groove 11a protrudes towards the direction away from the second shell plate body 12 and extends along the third direction. The reset spring 411 and the sliding block 412 are accommodated in the groove 11a, and the end of the reset spring 411 away from the sliding block 412 can be fixed to the bottom of the groove 11a, and the groove 11a can provide sufficient installation space for the reset spring 411 and the sliding block 412 to ensure smooth installation of the reset spring 411 and the sliding block 412. At least part of the inner wall of the groove 11a can abut the two sides of the sliding block 412 in the width direction of the sliding block 412, so that the groove 11a can play a good guiding and positioning role on the sliding block 412, and the movement accuracy and stability of the sliding block 412 can be improved to further improve the transmission stability and reliability of unlocking and locking of the door lock 100.

[0063] As shown in Figure 2 , Figure 3 and Figure 6 , according to some embodiments of the present application, the second shell plate body 12 has two opposite side walls in the width direction, and the two side walls are each provided with a first sliding rail part 121 extending along the third direction, and the latch 20 is provided with a protruding second sliding rail part 21 on both sides in the width direction, and the second sliding rail part 21 is adapted to abut the first sliding rail part 121.

[0070] As shown in the drawings, Figure 5 According to some embodiments of the present application, the second arm 32 of the unlocking member 30 is provided with a slide column 321 at one end away from the first arm 31, and the lock tongue 20 is provided with a slide groove 20a cooperating with the slide column 321.

[0071] Specifically, the second arm 32 can be provided with a slide column 321 at one end away from the first arm 31 in the extension direction, and the slide column 321 can be a convex cylindrical body, a prismatic body or a similar structure; the lock tongue 20 is provided with a slide groove 20a extending in the direction opposite to the first shell plate body 11 and the second shell plate body 12, and the slide groove 20a is used to cooperate with the slide column 321, and the shape and size thereof are matched with the slide column 321 to ensure that the slide column 321 can smoothly slide therein. During the unlocking process, when the unlocking member 30 is triggered (i.e. the user presses the button 50), the second arm 32 rotates in the first direction around the first end 31a of the first arm 31, and at the same time, the slide column 321 on the second arm 32 slides in the slide groove 20a, and the first end 31a of the first arm 31 is pivotally connected to the shell 10, so that through the cooperation of the slide groove 20a and the slide column 321, the slide column 321 can smoothly drive the lock tongue 20 to move in the third direction during the rotation of the unlocking member 30 around the first end 31a, ensuring that the lock tongue 20 accurately moves from the locking position to the unlocking position. Similarly, during the locking process, when the driving part 41 of the reset assembly 40 is triggered (driven by the elastic restoring force of the reset spring 411), the connecting rod 42 drives the second arm 32 to rotate in the second direction around the first end 31a of the first arm 31, and at the same time, the slide column 321 on the second arm 32 slides in the slide groove 20a to smoothly drive the lock tongue 20 to move in the third direction, so that the lock tongue 20 can accurately move from the unlocking position to the locking position. Through the cooperation of the slide column 321 and the slide groove 20a, the moving accuracy and reliability of the lock tongue 20 can be improved, and the overall mechanical efficiency and stability of the door lock 100 can also be improved.

[0072] As shown in the drawings, Figures 1-4 According to some embodiments of the present application, the door lock 100 further comprises a button 50, which comprises a body 51 and a connecting part 52. The body 51 is pressingly arranged outside the shell 10, and the connecting part 52 is arranged on one side of the body 51 in the thickness direction. The connecting part 52 penetrates the shell 10 and extends into the accommodating cavity 100a, and pushes against the connection area of the first arm 31 and the second arm 32 to selectively drive the second arm 32 to rotate in the first direction around the first end 31a of the first arm 31.

[0073] Specifically, the button 50 includes a body 51 and a connecting part 52. The body 51 is pressable and located outside the housing 10 so that the user can directly contact it to trigger the unlocking action, making the unlocking operation of the door lock 100 simple, intuitive, and easy to operate. The connecting part 52 can be located on the side of the body 51 closer to the housing 10 in the thickness direction. The connecting part 52 passes through the housing 10 and extends into the receiving cavity 100a. The end of the connecting part 52 away from the body 51 in the extending direction can abut against the connection area between the first arm 31 and the second arm 32. When unlocking is required, the user only needs to press the body 51. The body 51 moves and drives the connecting part 52 to move. The connecting part 52 then pushes the second arm 32 to rotate around the first end 31a of the first arm 31 in a first direction, thereby moving the bolt 20 to separate the bolt 20 from the lock groove 300a, thus successfully completing the unlocking.

[0074] Furthermore, in some specific embodiments of this application, the button 50 also includes a cover 54, which covers the side of the body 51 facing away from the housing 10 in the thickness direction. The cover 54, covering one side of the body 51, helps protect the body 51 and components such as the connecting part 52 from damage by the external environment. For example, the cover 54 can prevent dust, moisture, or other contaminants from entering the button 50 and the interior of the housing 10, thereby helping to maintain the cleanliness and good working condition of the components inside the button 50 and the housing 10, and improving the reliability and lifespan of the components. At the same time, the cover 54 can also provide a consistent appearance and texture for the door lock 100, enhancing the overall design and user experience.

[0075] In some other specific embodiments of this application, the connecting part 52 is provided with a headless screw 65 on the third-direction side, and the headless screw 65 is located in the receiving cavity 100a and abuts against the inner wall of the housing 10 to prevent the end of the connecting part 52 away from the body 51 from coming out of the receiving cavity 100a.

[0076] like Figure 3 and Figure 4 As shown, according to some embodiments of this application, an elastic element 53 is provided between the body 51 and the housing 10 on one side in the thickness direction.

[0077] Specifically, the elastic member 53 can be arranged between the body 51 of the button 50 and the shell 10 in the thickness direction. The elastic member 53 can be a spring, a rubber pad, or other materials with elasticity. The good elasticity of the elastic member 53 can provide a restoring force after the user presses the button 50, so that the button 50 can automatically return to the initial position. When the user presses the button 50, the body 51 of the button 50 moves towards the shell 10 under the action of external force, overcoming the resistance of the elastic member 53, and the connecting part 52 pushes the unlocking member 30 to rotate to unlock the lock tongue 20. Once the user releases the button 50, the elastic member 53 can release the energy stored in the unlocking process and push the body 51 and the connecting part 52 back to the initial position, and the door lock 100 automatically returns to the locked state under the cooperation of the reset assembly 40. By arranging the elastic member 53, the automatic reset function of the button 50 can be realized, the locking convenience is improved, and the elastic resistance provided by the elastic member 53 can also provide clear operation feedback to the user, so that the process of pressing the button 50 is comfortable and intuitive, and the user operation feeling and use experience are optimized.

[0078] In some embodiments of the present application, the second shell plate body 12 is provided with a limiting column 123 on the side away from the accommodating cavity 100a, and the body 51 is provided with a limiting hole matched with the limiting column 123. The limiting column 123 and the limiting hole can be matched to connect, position and limit between the body 51 and the second shell plate body 12, which helps to improve the assembly and positioning accuracy of the button 50 and the shell 10, and improve the assembly stability.

[0079] Further, in some embodiments of the present application, the limiting hole is configured as two limiting holes arranged in the extension direction of the body 51, the limiting column 123 is configured as two limiting columns corresponding to the limiting holes one by one, and the elastic member 53 is configured as two elastic members arranged in the extension direction of the body 51, and the two elastic members 53 are located between the two limiting columns 123 and the two limiting holes. By arranging two limiting holes, two limiting columns 123 and two elastic members 53, the structure stability and pressing stability of the button 50 can be improved.
